                               PROSPECTUS SUMMARY

     The following summary contains a general discussion of our businesses,  the
exchange offer and summary financial information.  We encourage you to read this
entire  prospectus  for a more  complete  understanding  of Concentra  Operating
Corporation,  the  subsidiary  guarantors  and  the  exchange  offer.  Concentra
Operating  became a wholly-owned  subsidiary of Concentra  Managed Care, Inc. on
August 17, 1999 as a result of the merger of  Concentra  and Yankee  Acquisition
Corp.

                                   OUR COMPANY

Who We Are

     We are the largest  company  primarily  dedicated to  providing  healthcare
services  relating to workplace  injuries  and  illnesses.  We have  developed a
delivery  model of  integrated  healthcare  services  to  reduce  costs  for our
customers. This model includes three distinct categories of services:

     o   Occupational  healthcare  services  involve the provision of healthcare
         services  to the  employees  of our  local  employer  customers.  These
         services include:

         -        injury care and physical  therapy  services  for  work-related
                  injuries and illnesses,

         -        physical examinations,

         -        substance abuse testing, and

         -        other loss prevention services.

     o   Specialized cost-containment services involve monitoring the timing and
         appropriateness of medical care, as well as the proper pricing for that
         care. These services include:

         -        First report of injury: A computerized reporting service using
                  two centralized  national call centers to which an employer or
                  insurance company adjuster communicates reports of injuries or
                  losses as soon as they occur.  For  injuries,  we then forward
                  the report to the appropriate  state agency,  the employer and
                  the insurance company to assist in the timely  preparation and
                  distribution  of  state-mandated  injury reports and providing
                  our customers with a tool to maximize control over the claim.

         -        Telephonic case  management: A service  using the telephone to
                  manage  workers'   compensation  claims  for  30  to  90  days
                  following the first report of injury. These units accept first
                  reports of injury,  negotiate  discounts  with  hospitals  and
                  other providers,  identify care alternatives and work with the
                  injured employees to minimize lost time on the job.

         -        Utilization  management:  A two-step service consisting of (1)
                  ensuring that medical  procedures  are certified by one of our
                  registered  nurses and/or physicians for medical necessity and
                  appropriateness  of treatment before the medical  procedure is
                  performed and (2) after a treatment plan has been certified, a
                  follow-up call by our employee to evaluate  compliance  and/or
                  discuss alternative treatment plans.

         -        In and  out-of-network  bill  review: A  service  where we use
                  sophisticated  software  programs  to review  and  reduce  our
                  customers medical bills, including hospital bills, both within
                  and  outside of their  healthcare  network,  to either the fee
                  mandated by the state for  workers'  compensation  claims or a
                  percentage of the usual,  customary and reasonable  rates that
                  exist in states that do not mandate  such fees.  In  addition,
                  our  software  also  enables our clients to access the pricing
                  schedules  of  some  preferred  providers  organizations  that
                  represent  additional savings below the state mandated fees or
                  customary rates.

                                       2

<PAGE>


         -        Preferred  provider  organization  network   access: A service
                  where we provide  injured  workers with access to our national
                  network of selected  medical  providers  capable of  providing
                  quality medical care and pre-negotiated volume discounts.

         -        Independent medical exams.

         -        Peer reviews: A service  where we review medical files for the
                  purpose of confirming that the care being provided  appears to
                  be necessary and appropriate.

     o Field-case  management  services involve assisting in the recovery of our
patients and expediting their return to work.

     Currently,  we  provide  initial  treatment  for  approximately  4% of  the
workplace  injuries in the United  States.  We perform  occupational  healthcare
services  for the  employees  of more than 80,000  local  employers  and provide
cost-containment   and  field-case   management  services  to  more  than  2,000
customers. We are the largest provider of out-of-network bill review services to
the group health market.

How and Where We Operate


     We provide  our  healthcare  services  through our network of 201 owned and
managed healthcare centers,  located in 60 markets in 32 states. We design these
centers to efficiently provide quality occupational healthcare services directly
to our  patients.  In addition,  they act as a starting  point for providing our
cost-containment  services.  We  also  employ  approximately  1,000  field  case
managers  nationwide  to work on a one-on-one  basis with injured  employees and
facilitate  communication among the employee's  doctors,  employer and insurance
carrier.


Our Strategy

     Our strategy includes the following elements:

     o   emphasizing early intervention in the provision of healthcare  services
         in order to better  identify cases that have the potential to result in
         significant  expenses for our clients,  particularly  lost work time by
         injured  employees,  administrative  or  legal  expenses,  and to  take
         appropriate measures to reduce these costs before they are incurred.

     o   continuing to acquire and develop  occupational  healthcare centers and
         expand  our  current  healthcare  network  into  both new and  existing
         markets.

     o   expanding our  penetration  of the group health market by offering more
         comprehensive out- of-network bill review services.

     o   continuing  to develop and integrate  our  information  systems to make
         more  effective  use of our  proprietary  knowledge  base  relating  to
         workplace injuries,  treatment protocols, the outcomes of treatment and
         the workers' compensation system's complex web of regulation.

     o   capitalizing on our national  organization and local market presence by
         offering  potential  clients  a  solution  to all of  their  healthcare
         management and cost containment needs.

Suite 400 West  Tower,  Addison,  Texas  75001.  Our  telephone  number is (800)

Risk Factors

     You  should  consider  all of the  information  in this  prospectus  before
tendering  your old notes in the exchange  offer.  The risks of an investment in
our company  include our  substantial  indebtedness,  our ability to make future
acquisitions and manage growth, and the potential for adverse regulatory impact.
See the "Risk Factors"  section of this prospectus for a discussion of these and
other risks involved in an investment in our company.

The Merger with Yankee


     On August 17, 1999,  Concentra  merged with Yankee  Acquisition  Corp. As a
result of the merger,  Concentra's common stock ceased to be publicly traded and
two new groups of equity investors each affiliated with Welsh, Carson,  Anderson
& Stowe VIII,  L.P. or Ferrer Freeman  Thompson & Co., LLC acquired an aggregate
93%  ownership  interest in  Concentra.  Chase  Capital  Partners,  employees of
Donaldson,  Lufkin & Jenrette Securities  Corporation and employees of Concentra
own the  remaining  interest.  We entered in several  financings,  including the
issuance of your old notes to fund the merger.  See "The Transactions and Use of
Proceeds."  Immediately  after  the  merger,  Concentra  contributed  all of its
assets, including all of the shares of its subsidiaries to our company.


     Our structure following each of the transactions related to our merger with
Yankee is reflected in the chart below (please note that  ownership  percentages
do not give effect to the exercise of warrants or options):

                  Operating Subsidiaries


                   SUMMARY OF THE TERMS OF THE EXCHANGE OFFER

     On August 17, 1999,  we completed  the private  offering of $190.0  million
principal  amount of our 13% senior  subordinated  notes due 2009. In connection
with that  offering,  we  agreed,  among  other  things,  to deliver to you this
prospectus  and to use our best efforts to complete  the exchange  offer by June

The Exchange Offer


     We are  offering to exchange  an equal  principal  amount of our 13% senior
subordinated  notes due 2009,  which have been  registered  under the Securities
Act, for our outstanding 13% senior  subordinated notes due 2009. In order to be
exchanged,  you must properly tender your outstanding note to us. You may tender
outstanding notes only in integral multiples of $1,000.



     As of this  date,  there  is  $190.0  million  principal  amount  of  notes
outstanding.  We will complete the exchange  offer  regardless of whether all or
less than all of the outstanding notes are tendered for exchange.

                                       5
<PAGE>

                   SUMMARY OF ABILITY TO RESELL THE NEW NOTES



     We believe that you may offer the new notes issued in this  exchange  offer
for resale,  or otherwise  transfer the new notes  without  compliance  with the
registration and prospectus  delivery provisions of the Securities Act, but only
if:



     o   you acquire the new notes in the ordinary course of business,

     o   you are not  participating,  do not intend to  participate  and have no
         arrangement  or  understanding  with any  person  to  participate  in a
         distribution of the new notes, and

     o   you are not an affiliate of ours,  as the term  affiliate is defined in
         Rule 405 under the  Securities  Act and which may include our executive
         officers  and  directors,   another  person  having  control  over  our
         operations or management or an entity we control.

     By executing and delivering the letter of  transmittal,  you will represent
to us that the above  statements by you are true. If any of these statements are
untrue,  you may not resell your notes unless an exemption from the registration
provisions  of the  Securities  Act is available  for the transfer or you resell
your  notes  in  compliance  with  the  prospectus  delivery  provisions  of the
Securities Act.


     Each  broker-dealer  that is issued new notes in the exchange offer for its
own account in exchange for old notes which were  acquired by the  broker-dealer
as a result of market-making or other trading activities,  must acknowledge that
it will deliver a prospectus  meeting the  requirements of the Securities Act in
connection  with any  resale  of the new  notes.  A  broker-dealer  may use this
prospectus,  as we may amend or supplement it from time to time, for an offer to
resell, resale or similar transfer of the new notes issued to it in the exchange
offer.


                      SUMMARY DESCRIPTION OF THE NEW NOTES

Notes Offered


     We are offering  $190.0 million  aggregate  principal  amount of 13% senior
subordinated  notes due 2009.  The indenture will make the form and terms of the
new notes the same as the form and terms of the old notes except that:


     o   the new notes will bear a different CUSIP number from the old notes,


     o   the   exchange offer  will  register  under  the  Securities  Act  and,
         therefore  the  new  notes,  will  not  bear  legends restricting their
         transfer, and

     o   registration  rights will not apply to the new notes.

     The new notes will  evidence the same debt as the old notes,  the indenture
and will entitle the new notes to the same benfits  governing  the old notes and
will treat the new notes as a single class with the old notes.

Issuer


     The indenture makes Concentra Operating Corporation is liable for repayment
of the new notes.


Maturity

     August 15, 2009.

Interest Payment Dates

     We will pay  interest  on the notes on  February  15 and  August 15 of each
year, beginning February 15, 2000.

                                       6
<PAGE>

Subsidiary Guarantees


     Each of our  subsidiaries,  other than our joint ventures,  is a guarantor.
Each guarantee is for the full amount of the notes and without condition.  If we
cannot make payments on the notes when they are due, the indenture obligates the
guarantor subsidiaries to make them instead.


Ranking


     The indenture  subordinates the notes and the subsidiary  guarantees to all
our  senior  debt,  including  all our debt  under  our  senior  secured  credit
facilities.  The notes rank equally with any senior  subordinated debt, and rank
senior  to all our  subordinated  debt.  The  notes  rank  below  our  guarantor
subsidiaries' current and future indebtedness, other than trade payables, except
indebtedness that expressly provides that it is equal or subordinate in right of
payment to these notes and the subsidiary guarantees.



     On September 30, 1999, the notes ranked junior to $375.6 million of senior
debt under our credit facilities and indebtedness of our subsidiary guarantors.


Optional Redemption

     We may  redeem  any  of the  notes  on or  after  August  15,  2004  at the
redemption  prices set forth in the "Description of the Notes" section under the
heading "Optional Redemption."

     Prior  to  August  15,  2002,  we may  redeem  up to  25% of the  aggregate
principal amount of the then  outstanding  notes with the net proceeds of one or
more equity offerings at 113% of their principal amount, plus accrued and unpaid
interest.

Mandatory Offer to Repurchase

     If we experience specific kinds of changes in control or engage in sales of
specific  assets,  we must offer to  repurchase  any  then-outstanding  notes at
prices  listed  in  the  section   "Description  of  Notes"  under  the  caption
"Repurchase at the Option of Holders."

Covenants

     The indenture  governing the notes  contains  covenants  that,  among other
things, limit our ability and the ability of some of our subsidiaries to:

     o   incur additional debt,

     o   pay dividends on, redeem or repurchase our capital stock,

     o   make investments,

     o   restrict dividend or other payments to us,

     o   enter into transactions with affiliates or related persons,

     o   guarantee indebtedness,

     o   sell assets,

     o   create liens,

     o   engage in a merger, sale or consolidation, and

     o   enter into new lines of business.

     These  covenants are subject to important  exceptions  and  qualifications,
which are described in the section  "Description of the Notes" under the caption
"Certain Covenants" in this prospectus.

          SUMMARY HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL DATA


     Set forth below are our summary historical and pro forma financial data. We
derived the summary historical  consolidated  financial data for the three years
ended December 31, 1998 from, and you should read them in conjunction  with, the
audited  consolidated  financial  statements  of Concentra  and related notes to
those financial statements included elsewhere in this prospectus. We derived the
summary historical  consolidated financial data as of September 30, 1999 and for
the nine month  periods  ended,  September  30, 1998 and 1999 from the unaudited
consolidated  financial  statements of Concentra Operating which, in the opinion
of management,  includes all adjustments,  consisting only of normal,  recurring
adjustments,  necessary for a fair  presentation of our  consolidated  financial
condition and results of operations as of and for those  periods.  The operating
results  for the nine month  periods  ended  September  30, 1998 and 1999 do not
necessarily indicate of results to be expected for the full year.


     The pro forma data as of and for the periods  presented  give effect to the
issuance of $565.0  million of new debt and the  repurchase of $327.9 million of
existing   indebtness  in  connection  with  the  merger  and   recapitalization
transactions  as if  they  were  consummated  at the  beginning  of  the  period
indicated.


     The accompanying  consolidated financial statements as of December 31, 1998
and  September  30, 1999 and for the three and nine months ended  September  30,
1998 and 1999 and related  footnotes  reflect the operating results of Concentra
through  August 17, 1999 and the operating  results of Concentra  Operating from
August  18,  1999  through  September  30,  1999.   Concentra   Operating  is  a
wholly-owned  subsidiary of Concentra and we consider them entities under common
control,  therefore,  combined financial statements have been presented. We have
not  reported  earnings  per  share  for all  periods  presented,  as  Concentra
Operating is a  wholly-owned  subsidiary  of Concentra  and has no publicly held
shares. You should read the summary historical  consolidated  financial data set
forth below  together  with,  and we qualify  that data in its  entirety by, the
"Selected Historical Consolidated Financial Data," "Management's  Discussion and
Analysis of Financial  Condition and Results of Operations" and the consolidated
financial  statements  of  Concentra  and  notes to those  financial  statements
included elsewhere in this prospectus.

</TABLE>

      (a)   The 4.5% convertible subordinated notes were issued in March ($200.0
            million) and April ($30.0  million) of 1998,  as such,  the interest
            expense does not reflect a full year of interest expense.

      (b)   We assume that The  Eurodollar  Rate (E.R.) is 5.4% for the purposes
            of calculating  interest expense. The annual effect of a 1/8% change
            in the interest  rate on the $375.0  million  variable  rate debt is
            $0.5  million for the year ended  December 31, 1998 and $0.4 million
            for the nine months ended September 30, 1999.
      (c)   We are amortizing the deferred  finance  fees  of $18.0 million over
            the weighted average life of the new debt of 8.2 years.

      (d)   Interest  expense  recorded  through   September  30,  1999  on  new
            indebtedness issued in connection with the merger.
      (e)   To  record  the  decrease  in  interest  income  due to  the  use of
            available cash.
      (f)   To record the tax benefit on the pro forma interest adjustments.

(3)  As a result of Concentra going private in the merger transaction, there are
     no longer  publicly held shares  outstanding and we believe that historical
     earnings per share information is not meaningful.

(4)  EBITDA  represents net income before  interest  expense,  interest  income,
     provision for income taxes,  depreciation  and  amortization of intangibles
     and includes  depreciation and amortization of two 50% owned joint ventures
     not  consolidated by Concentra.  Adjusted EBITDA  represents  EBITDA before
     non-recurring charges. EBITDA is a measure commonly used by debt holders in
     assessing a company's leverage.  It provides debt holders with a measure of
     cash flow  available  to meet debt service and  interest  payments.  EBITDA
     calculations  can vary by  company.  We based our calculation   on specific
     provisions  provided  for in  your  note  agreement.  Your  note  agreement
     specifically  provides  that  we add  back  depreciation  and  amortization
     amounts associated with our two 50% owned joint ventures.  We do not intend
     EBITDA  and  Adjusted  EBITDA to  represent  cash flow from  operations  as
     defined by generally accepted accounting principles. We prepare a statement
     of cash flows,  which  measures  changes in working  capital and cash flows
     from operations,  investing activities and financing activities. For a more
     relevant  calculation of the sources and uses of Concentra's cash flows and
     additional  information with respect to our ability to meet our future debt
     service, capital expenditures and working capital requirements, see F-5 and
     F-16 in this prospectus.

(5)  Cash interest expense  represents  interest expense that we recorded during
     the period excluding the amortzation of debt issuance costs.

(6)  We compute the ratio of earnings  to fixed  charges by dividing  the sum of
     net  earnings,  before  deducting  provisions  for  income  taxes and fixed
     charges,  and we  adjust  for the  equity  in  earnings  of  unconsolidated
     subsidiaries  and related  distributions,  by fixed charges.  Fixed charges
     consist of interest on debt, including amortization of debt issuance costs,
     and one-fourth of rent expenses, which management estimates as the interest
     component of such  rentals.  The ratio of earnings to fixed  charges is not
     adequate to cover fixed  charges for the pro forma year ended  December 31,
     1998 and the nine month and pro forma nine month  periods  ended  September
     30, 1999, by $5.2 million, $14.7 million, and $43.2 million, respectively.

     acquired and  subsequently  divested or consolidated  into existing centers
     within a market.

(8)  The decline in field case  management  offices in 1998 is primarily  due to
     the  fourth  quarter  of  1998   reorganization   which  included  facility

                               RECENT DEVELOPMENTS

     Our revenues for the  three-month  period ended December 31, 1999 increased
15% to $175.3  million  from $151.9  million for the  three-month  period  ended
December 31, 1998. Our adjusted EBITDA for the three-month period ended December
31, 1999  increased 9% to $22.5 million from $20.7  million for the  three-month
period ended December 31, 1998. Our operating income for the three-month  period
ended  December 31, 1999  increased to $12.2 million from a loss of $6.3 million
for the  three-month  period  ended  December  31,  1998.  Our net  loss for the
three-month period ended December 31, 1999 decreased to $2.0 million from a loss
of $5.0 million for the three-month period ended December 31, 1998.

     Our revenues for the year ended  December 31, 1999  increased 12% to $681.4
million from $611.1  million for the year ended  December 31, 1998. Our adjusted
EBITDA for the year ended  December 31, 1999 decreased 6% to $104.7 million from
$111.7 million for the year ended  December 31, 1998.  Our operating  income for
the year ended  December 31, 1999  decreased to $14.3 million from $55.2 million
for the year December 31, 1998. Our net income for the three-month  period ended
December 31, 1999  decreased to a loss of $26.5 million from net income of $22.5
million for the three-month period ended December 31, 1998.

     Our net  income  for the full year  ended  December  31,  1999,  includes a
non-recurring  charge of $54.4  million,  $45.9  million on an after-tax  basis,
incurred  in the  third  quarter  of  1999  primarily  for  fees,  expenses  and
restructuring  charges  associated with the merger.  Similarly,  results for the
three-month  period ended December 31, 1999 and the year ended December 31, 1999
include non recurring  charges of $20.5  million,  $12.1 million on an after-tax
basis, and $33.1 million, $21.7 million on an after-tax basis, respectively. The
fourth quarter charge primarily reflects expenses related to severance, facility
closings and consolidation, as well as the write off of some assets. Our results
for the year ended  December  31, 1998  include a charge taken during that year,
which reflected fees,  expenses and restructuring  charges primarily  associated
with its acquisition of Preferred Payment Systems, Inc.

                                  RISK FACTORS

     You should carefully consider the following factors,  and the other factors
described in this  prospectus  before deciding to exchange the old notes for new
notes.  Any of the following  risks could have a material  adverse impact on our
business  financial  condition or results of  operations  or on the value of the
notes.

Risks Applicable to the Notes

If  we  cannot  generate  cash,  then  we  will  not  be  able  to  service  our
indebtedness.

     As of September 30, 1999, our consolidated  indebtedness was  approximately
$566.0 million. This represents  approximately 107% of our total capitalization.
In addition,  our business strategy calls for significant  capital  expenditures
for acquisition and development. The indenture governing the notes and our other
debt instruments  allow us to incur additional  indebtedness,  including secured
indebtedness  and $98.55  million of unused  drawing  capacity  under the senior
credit  facilities.  See  "Management's  Discussion  and  Analysis of  Financial
Condition and Results of Operations--Liquidity and Capital Resources."

     Our  ability  to  make  payments  on and  to  refinance  our  indebtedness,
including the notes, and to fund planned capital expenditures will depend on our
ability to generate cash in the future.  Over the next year, we will be required
to make debt  payments of $3.8  million  and  interest  payments  related to the
Company's debt of approximately $65.0 million.

     We believe  our cash flow from  operations,  available  cash and  available
borrowings  under the senior credit  facilities will be adequate to carry on our
business strategy.  However,  our ability to generate cash is subject to general
economic and industry conditions that are beyond our control.  Therefore,  it is
possible,  that our  business  will  not  generate  sufficient  cash  flow  from
operations  or that  future  borrowings  will not be  available  to us under the
senior  credit  facilities  in an  amount  sufficient  to  enable  us to pay our
indebtedness, including the notes, or to fund our other liquidity needs.

If we go  bankrupt,  liquidate  or  reorganize,  then you may not  receive  full
payment on your notes.


     The indenture does not secure the notes nor the guarantees  with any of our
or the subsidiary guarantors assets. Further, the notes and guarantees will rank
below our senior debt and most of the subsidiary guarantors existing indebtness.
Accordingly,  in the event of a bankruptcy,  liquidation  or  reorganization  or
similar proceeding relating to Concentra Operating or the subsidiary guarantors,
holders of the notes will participate with all other holders of our subordinated
indebtedness and the subsidiary  guarantors in the assets remaining after we and
the subsidiary  guarantors have paid all of the senior debt. As of September 30,
1999, our consolidated  indebtedness was $566.0 million, $376.0 million of which
has ranked  senior to the  notes,  and we had $98.5  million  of unused  drawing
capacity  under the senior credit  facilities.  The subsidiary  guarantors  have
$376.0 million of  indebtedness  ranking senior to the  guarantees.  Because our
senior debt must be paid first, you may receive  proportionately less than trade
creditors  and other senior  creditors in any such  proceeding.  In any of these
cases, we and the subsidiary guarantors may not have sufficient funds to pay all
of our creditors,  therefore, holders of the notes may receive ratably less than
trade creditors.


If our  subsidiaries  cannot  distribute  cash to us, then we may not be able to
repay the notes.


     We depend on the cash flow from our  subsidiaries to meet our  obligations,
including all payments on the notes.  Accordingly,  our ability to make payments
to holders  of the notes  depends on the  receipt of  sufficient  funds from our
subsidiaries. The possible terms of instruments governing future indebtedness of
our  subsidiaries may secure  that  future  indebtedness  with the assets of our
subsidiaries,  and as a result  those  governing  instruments  may  restrict our
ability to receive  funds from our  subsidiaries.  The  indenture  for the notes
permits our subsidiaries to enter into agreements  which restrict  dividends and
distributions  to the obligors under some  circumstances.  See  "Description  of
Notes--Certain   Covenants--Other   Payment  Restrictions  Affecting  Restricted
Subsidiaries."



                                       12
<PAGE>


     Although we can use the cash distributed by our joint ventures to us or our
subsidiaries to make payments on the notes,  our joint ventures do not guarantee
the notes.



Restrictions imposed by the senior credit facilities and the indenture will make
it more difficult for us to take the actions listed below.


     The senior credit facilities and the indenture restrict our ability to:


     o   make investments;


     o   pay dividends and make distributions;

     o   repurchase stock;

     o   incur additional indebtedness;

     o   create liens;

     o   merge or consolidate our company or any of our subsidiaries;

     o   transfer and sell assets;

     o   enter into transactions with our affiliates;

     o   enter into sale and leaseback transactions; and

     o   issue common and preferred stock of our subsidiaries.


     In addition,  we must  maintain  minimum debt service and maximum  leverage
ratios  under the senior  credit  facilities.  We  calculate  these  ratios on a
rolling   four-quarter   basis.  The  debt  service  ratio  and  leverage  ratio
requirements  for the quarter ended December 31, 1999 were 1.75 to 1.00 and 5.50
to 1.00,  respectively.  We were in compliance with these ratios at December 31,
1999,  with a debt service  ratio of  approximately  2.33 to 1.00 and a leverage
ratio of approximately  5.35 to 1.00. The indenture makes our debt service ratio
and leverage ratio requirements or the quarter ended March 31, 2000 2:00 to 1:00
and 5:25 to 1:00,  respectively.  We have  contacted  the agent under our senior
credit  facilities in order to review  whether an amendment to these  compliance
ratios is necessary for future periods. Although we believe that we will succeed
in  these  efforts,  we  cannot  assure  you that the  banks  will  agree to any
amendment  of the  senior  credit  facilities  in the event that we find such an
amendment is necessary.  Furthermore,  these ratios become more  restrictive  in
future  quarters.  Our ability to be in compliance  with these more  restrictive
ratios will be dependent upon our ability to increase our cash flow over current
levels.

     A failure to comply with these restrictions or maintain these ratios in the
future could lead to an event of default  which could result in an  acceleration
of the  related  indebtedness  before the terms of that  indebtedness  otherwise
require us to pay that indebtedness.  Such an acceleration would also constitute
an event of default under the indenture  relating to the notes. See "Description
of Certain  Indebtedness"  and  "Description  of  Notes-Events  of  Default  and
Remedies" and "Management's  Discussion and Analysis of Financial  Condition and
Results of Operations--Liquidity and Capital Resources."


If the  interests of Welsh Carson  diverge from the  interests of the holders of
the notes, you may experience additional risk.

     Welsh  Carson  controls a majority of the voting  power of the  outstanding
common  stock  of  Concentra  and  controls  all of our  affairs  and  policies.
Circumstances  may  occur in which the  interests  of Welsh  Carson  could be in
conflict  with the  interests of the holders of the notes.  In  addition,  Welsh
Carson may have an  interest  in pursuing  acquisitions,  divestitures  or other
transactions  that, in their  judgment,  could enhance their equity  investment,
even though such  transactions  might involve risks to the holders of the notes.
See "Management" and "Certain Relationships and Related Transactions."


                                       13
<PAGE>


If we don't have enough cash or the ability to borrow the  necessary  funds,  we
may not be able to repurchase the notes.


     Upon the occurrence of certain  specific kinds of change of control events,
the indenture  requires us to offer to repurchase all  outstanding  notes.  Upon
such events, the indenture also obligates us to repay the outstanding  principal
amount  under  our  credit  facilities  and the  accreted  value of  Concentra's
discount  debentures.  As of  September  30,  1999,  we had  $375.6  million  in
outstanding  principal amount under our credit  facilities and $110.0 million in
accreted value under Concentra's discounted  debentures.  Of this amount we must
repay the senior credit  facilities  prior to the repurchase of the notes.  As a
result, it is possible that we will not have access sufficient funds at the time
of the change of control to make the required  repurchase of notes.  Further, at
the time such  repurchase is to occur,  it is possible that the  restrictions in
the senior credit facilities will not allow such  repurchases.  See "Description
of Notes--Repurchase at the Option of Holders."

Bankruptcy law would impair your rights to be repaid if a court  determined that
we issued the notes for inadequate  consideration  or with intent to defraud our
creditors.

     Bankruptcy  law would impair our ability to repay the notes and the ability
of our  subsidiary  guarantors to honor the  guarantees if it is determined in a
bankruptcy, insolvency or similar proceeding that:


     o   we issued the notes or the subsidiary  guarantors issued the guarantees
         with the intent to delay or defraud any creditor;

     o   we or the subsidiary guarantors  contemplated  insolvency with a design
         to prefer some creditors to the exclusion of others; or

     o   we issued the notes or the subsidiary  guarantors issued the guarantees
         for less than  reasonably  equivalent  value and were  insolvent at the
         time the notes or guarantees were originally issued.

     At the time of the merger,  Concentra  received  the  opinion of  Valuation
Research, Inc. stating that it was not insolvent following the completion of the
merger and related  financing  transactions.  Although we do not believe  that a
court could find that we were  insolvent  at the time we issued the notes and we
believe that we issued the notes at their  reasonably  equivalent  value,  it is
possible  that we may one day become  insolvent.  In such event,  a court could,
among other things,  void all or a portion of our and the subsidiary  guarantors
obligations  to you.  In this case,  you may not be repaid in full.  A court may
also subordinate these obligations to our other indebtedness to a greater extent
than  would  otherwise  be the case.  In this  case,  other  creditors  would be
entitled to be paid in full before any payment could be made on the notes or the
guarantees.

If an  active  trading  market  does  not  develop,  you may  have  difficulties
reselling the notes.


     Prior to the  offering,  there  was no public  market  for the  notes.  The
initial  purchasers  have  informed  us that  they are  making a market in these
notes.  However,  the initial  purchasers may cease their  market-making  at any
time. In addition,  changes in the overall market for high yield  securities and
changes in our  financial  performance  or  prospects  or in the  prospects  for
companies  in our  industry  generally  may reduce the  liquidity of the trading
market in the notes and the market price quoted for the notes.


If you do not exchange your old notes for new notes, your old notes may trade at
discount because you may not be able to transfer such notes.


     In the event the  exchange  offer is  completed,  the  registration  rights
agreement  will not  require us to register  the old notes under the  Securities
Act. In such event, the new notes would rank equally with the old notes. Holders
of old  notes  seeking  liquidity  in  their  investment  would  have to rely on
exemptions from registration  requirements under the securities laws,  including
the  Securities  Act. A reduction of the aggregate  principal  amount of the old
notes as a result of the completion of the exchange  offer may adversely  effect
the ability of holders of the old notes to transfer such notes.

Risks Applicable to the Business


If we cannot make future acquisitions or enter into joint ventures successfully,
that lack of success may impair our  planned growth.

     Our business strategy requires us to negotiate the purchase of occupational
healthcare  centers  and enter  into  joint  ventures  to  operate  occupational
healthcare  centers.  A strategy of growth by  acquisition or joint venture also
involves the risk of assuming unknown or contingent  liabilities of the acquired
business or joint  venture,  which  could be  material,  individually  or in the
aggregate.  Nevertheless,  we may not be able to find  suitable  acquisition  or
joint venture  candidates,  or, if we do finance or consummate such transactions
on  favorable  terms.  In  addition,  we cannot  assure you we can  successfully
integrate the  operations of any completed  acquisitions  or joint ventures into
our own.


Our  continued  rapid  growth  could cause our  management  to lose focus on all
aspects of our business,  our response  time to customer  inquiries to increase,
our customer service to decline in quality and other similar effects.

     We have  experienced  rapid growth.  Our recent and continued  rapid growth
could place a significant  strain on our  management and other  resources.  This
strain  could  consist  of our  management  not having  enough  time to focus on
managing  all aspects of our  business  and  operations,  our  response  time to
customer  inquiries to increase,  our customer service to decline in quality and
other  similar  effects.  Our rapid  growth  will not affect the quality of care
provided by our affiliated  physician  associations or employees.  We anticipate
that any continued  growth will require us to 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. We
may be unable to slow our  growth  without  increasing  our costs if  management
becomes strained.  Our ability to compete  effectively and to manage current and
any future  growth  will depend on our  ability to  continue  to  implement  and
improve  operational,  financial and management  information systems on a timely
basis and to  expand,  train,  motivate  and  manage  our  workforce.  Should we
continue  to  experience  rapid  growth,  we cannot  assure you that  personnel,
systems,  procedures  and controls will be adequate to support our operations or
that management will adequately anticipate all demands that growth will place on
us. If we are unable to meet  increasing  demand we may lose  customers  and our
revenues may decrease.


If competition increases, our growth and profits may decline.

     The market to provide occupational healthcare services is highly fragmented
and  competitive.  Our  primary  competitors  have  typically  been  independent
physicians,    hospital    emergency    departments   and    hospital-owned   or
hospital-affiliated medical facilities.


     We believe that, as managed care techniques  continue to gain acceptance in
the  occupational  healthcare  marketplace,  our competitors  will  increasingly
consist  of  nationally  focused  workers'  compensation  managed  care  service
companies,  specialized provider groups, insurance companies,  health management
organizations  and other significant  providers of managed care products.  These
organizations  may be  significantly  larger  and  have  greater  financial  and
marketing resources than we do. Accordingly,  competitors may affect our ability
to continue to maintain  our  existing  performance  or our success with any new
products or in any new geographic markets we may enter.


If healthcare reform  intensifies  competition and reduces the costs of workers'
compensation claims, the rates we charge for our services could decrease.

     Legislative  reforms in some states  permit  employers to designate  health
plans  such  as  health   management   organizations   and  preferred   provider
organizations  to cover  workers'  compensation  claimants.  Because many health
plans  have  the  capacity  to  manage  healthcare  for  workers'   compensation
claimants,  that  legislation may intensify  competition in the market we serve.
Within the past few years,  several  states have  experienced  decreases  in the
number of workers'  compensation claims and the total value of claims which have
been reflected in workers'  compensation  insurance  premium rate  reductions in
those states. We believe that declines in workers'  compensation  costs in these
states  are due  principally  to  intensified  efforts  by payors to manage  and
control claim costs, to improved risk management by employers and to legislative
reforms. As these costs decrease,  we may have to reduce the rates we charge for
our services in order to effectively compete.

If suits against us are successful, we may incur significant liabilities.


     Our  affiliated  physician  associations  and  some  of our  employees  are
involved in the delivery of healthcare services to the public. In each case, the
physician makes all decisions  concerning the appropriate  medical treatment for
the patient based on his or her prior medical  experience  and experience in the
treatment of occupational healthcare injuries. We charge our customers for these
services  on a  fee-for-service  basis.  We base  these fees on either the state
mandated fee or the usual and customary rate for such services,  as appropriate.
In providing these services, the physicians,  7 our employees and, consequently,
our company are exposed to the risk of professional  liability claims.  Although
we have not faced any material lawsuits in the past that were not covered by our
insurance,  claims of this nature,  if  successful,  could result in substantial
damage  awards to the  claimants  which may exceed the limits of any  applicable
insurance coverage.  We are indemnified under our management agreements with our
affiliated  physician  associations from claims against them, maintain liability
insurance for ourselves and negotiate  liability insurance for the physicians in
our affiliated physician  associations.  However,  successful malpractice claims
asserted  against us or our affiliated  physician  associations  could result in
significant  liabilities  that  are not  indemnified  by the  physicians  or our
insurance.  Further,  plaintiffs have proposed new types of liabilities  against
managed  care  companies  as well as against  employers  who use managed care in
workers' compensation cases which, if established and successful, may discourage
the use of managed  care in  workers'  compensation  cases and could  reduce the
number of claims referred to us or the rates we charge for our services.

     Through  our  specialized   cost  containment  and  field  case  management
services,  we make  recommendations  about  the  appropriateness  of  providers'
proposed medical  treatment plans of patients  throughout the country,  and as a
result  we could  be  subject  to  charges  arising  from  any  adverse  medical
consequences.  We do not grant or deny claims for payment of benefits  and we do
not  believe  that we engage in the  practice  of  medicine  or the  delivery of
medical  services.  Although  plaintiffs  have not subjected us to any claims or
litigation  related to the grant or denial of claims for  payment of benefits or
allegations  that we engage in the  practice  of  medicine  or the  delivery  of
medical  services so far,  we cannot  assure you that  plaintiffs  will not make
those types of claims or litigation.  We maintain errors and omissions insurance
and such other lines of coverage  as we believe are  reasonable  in light of our
experience  to date.  We cannot assure you,  however,  that our  insurance  will
provide  sufficient  coverage or that  insurance  companies  will make insurance
available at reasonable cost to protect us from liability.


If corporate  practice of medicine and other laws and  regulations  increase our
costs, our profits may decline.


     State laws  relating  to our  business  vary widely from state to state and
courts or regulatory agencies seldom interpret those laws in a way that provides
guidance with respect to our business operations.  In addition, many states have
licensing or regulatory  programs and we may incur  significant costs due to the
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.  In addition,  these regulatory programs may
result in increased  costs of operation for us, which may have an adverse impact
on our ability to charge  competitive  rates for our services while  maintaining
profitability.


     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 like us and
licensed professionals and professional corporations,  particularly with respect
to  fee-splitting   between  a  physician  and  another  person  or  entity  and
non-physicians  exercising  control over  physicians  engaged in the practice of
medicine.


     Laws and  regulations  relating to the practice of medicine,  fee-splitting
and similar issues vary widely from state to state,  are often vague, and courts
or regulatory  agencies  seldom  interpret  those laws in a manner that provides
guidance with respect to business  operations such as ours.  Although we attempt
to structure all of our  operations so that they comply with the relevant  state
statutes and applicable  medical  practice,  fee-splitting and similar laws, any
new  interpretation  of these laws  could  significantly  increase  our costs of
operations or result in substantial liabilities.

     In addition,  state agencies  regulate the automobile  insurance  industry,
like the workers'  compensation  industry,  on a state-by-state  basis. Although
regulators  do not require  approval for us to offer most of our services to the
automobile insurance market, State regulators require approval in order to offer
automobile  insurers'  products  that  permit  them to direct  claimants  into a
network of medical  providers.  Changes in these  regulations  may  increase our
costs.

If fraud and abuse laws change, we may incur significant liabilities.

     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
statutory anti-referral  provisions,  known as the Stark Amendments,  prohibit a
physician  with a  "financial  relationship"  with 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 associations  affiliated with
us.

     At least  seven of the states  where we  conduct  our  healthcare  services
business--Arizona,  California,  Florida,  Illinois,  Maryland,  New  Jersey and
Texas--have  enacted statutes similar in scope and purpose to the  Anti-Kickback
Statute,  which are  applicable 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
that  have  not  enacted  that  kind of  statute,  we  believe  that  regulatory
authorities and state courts  interpreting these statutes may regard federal law
under the Anti-Kickback Statute as persuasive.


     We believe that our arrangements with our affiliated physician associations
should  not  violate  the  Anti-Kickback   Statute,  the  Stark  Amendments  and
applicable state laws.  However,  appropriate  authorities  subject all of these
laws to  modification  and  interpretation  and appropriate  authorities  seldom
interpret  these  laws in a  manner  that  provides  guidance  to our  business.
Moreover these laws are enforced by authorities vested with broad discretion. We
have  attempted  to  structure  all of our  operations  so that they  should not
violate any applicable anti-kickback and anti-referral prohibitions.

     We also  continually  monitor  developments  in this area.  If  appropriate
authorities interpret these laws in a manner contrary to our interpretation, are
reinterpreted  or amended,  or if new  legislation  is enacted  with  respect to
healthcare  fraud and abuse or similar  issues,  we will seek to restructure any
affected operations so as to maintain compliance with applicable law.

If our data  processing  is  interrupted  or our  licenses to use  software  are
revoked, that  interruption or revocation may impair our ability to  effectively
operate our business.

     Certain  aspects of our business are  dependent  upon our ability to store,
retrieve,  process  and  manage  data  and to  maintain  and  upgrade  our  data
processing  capabilities.  Interruption of data processing  capabilities for any
extended  length  of time,  loss of  stored  data,  programming  errors or other
computer problem could impair our ability to provide these services.  Certain of
the software that we used in our medical bill review  operation is licensed from
an independent  third party software  company under a nonexclusive  license that
may  be  terminated  by  either  party  upon  90  days  notice.  While  we  have
historically  maintained a good relationship with the licensor, we cannot assure
you that the  licensor  will not  terminate  this  software  license or that the
licensor  will  continue the license on its  existing  terms.  We are  currently
negotiating  an extension  of this  software  license.  Although we believe that
alternative software would be available if the existing license were terminated,
termination  could  disrupt  and could  result in our  inability  to operate our
business,  including  our  ability to  effectively  review  medical  bills.  See
"Business Information Systems and Technology."

If we lose key personnel,  the loss of that personnel will impair our ability to
implement our strategy..


     Our success depends in large part on the services of our senior  management
team. We have employment contracts with all of our key personnel;  however we do
not maintain key man life  insurance  policies.  In any case, the loss of any of
our key executives could materially adversely affect us and seriously impair our
ability to implement our strategy.  Our ability to manage our anticipated growth
will depend on our ability to  identify,  hire and retain  additional  qualified
management personnel. We have recently experienced high employee turnover, which
is typical in our industry,  but our key personnel  have remained with us. While
we are able to offer competitive  compensation to


                                       17
<PAGE>


prospective employees,  we may still be unsuccessful in attracting and retaining
personnel and that failure could result in our growth  declining and  materially
adversely affect our results of operation. See "Management."

               THIS PROSPECTUS INCLUDES FORWARD LOOKING STATEMENTS


     This  prospectus  includes   "forward-looking   statements"  including,  in
particular,  the statements about our plans,  strategies and prospects under the
headings  "Prospectus  Summary,"  "Risk Factors,"  "Management's  Discussion and
Analysis of  Financial  Condition  and Results of  Operations"  and  "Business."
Although we believe that these forward-looking statements reasonably reflect our
plans,  intentions  and  expectations,  we can  give no  assurance  that we will
achieve these plans,  intentions or expectations.  Important  factors that could
cause actual results to differ materially from the forward-looking statements we
make in this  prospectus are in this  prospectus,  including  under the headings
"Prospectus Summary," "Risk Factors,"  "Management's  Discussion and Analysis of
Financial  Condition and Results of Operations"  and  "Business."  These factors
include:


     o   the effects of economic conditions;

     o   the impact of  competitive  services  and  pricing,  including  through
         legislative reform;

     o   changes in accounting  standards and regulations  affecting the workers
         compensation, insurance and healthcare industries in general;

     o   customer demand;

     o   changes in costs; and

     o   opportunities  that others may present to us or that we may pursue, all
         of which are difficult to predict and beyond the control of management.

     All forward-looking  statements attributable to us or persons acting on our
behalf are expressly  qualified in their entirety by the  cautionary  statements
and risk factors contained throughout this prospectus.  In light of these risks,
uncertainties  and assumptions,  the  forward-looking  events we discuss in this
prospectus might not occur.

third  party data or we  derived it from  sources  of  industry  data.  While we
believe that the estimates are  reasonable and reliable,  in certain cases,  the
estimates cannot be verified by information  available from independent sources.
Accordingly, we can give no assurance that the market share data are accurate in
all material respects.

                      THE TRANSACTIONS AND USE OF PROCEEDS

     The  following  is a summary of the  structure  of, and  conditions  to the
completion  of,  the  merger  and  related  transactions.  This  summary  is not
complete.  For a more  complete  understanding  of the terms of the merger,  you
should  read the  merger  agreement,  a copy of which  has been  filed  with the
Commission.

Structure of the Merger

     Under the  merger  agreement  Yankee  merged  with and into  Concentra  and
Concentra was the surviving  corporation in the merger. At the effective time of
the merger:


     o   the stockholders of Concentra,  including  option holders,  received an
         aggregate of $694.6 million in cash,  without interest,  for the shares
         of Concentra  common stock,  other than shares held by Yankee,  and "in
         the money" stock options that they own.  The merger agreement cancelled
         shares held by Concentra,  its subsidiaries,  Yankee or its  affiliates
         in the merger; and



                                       18
<PAGE>



     o   the merger agreement  converted each outstanding  share of common stock
         of Yankee into one share of common stock of the same class of Concentra
         the surviving corporation in the merger.

     As a result of the merger, the Concentra common stock ceased to be publicly
traded.  The surviving  corporation in the merger continues to operate under the
name "Concentra  Managed Care,  Inc."  Immediately  after the merger,  Concentra
transferred   all  of  its  existing   assets,   including  the  shares  of  its
subsidiaries, to Concentra Operating.


     As a result of the merger, the Welsh Carson investors acquired an ownership
interest  of  approximately  86% in  Concentra  and Ferrer  Freeman  acquired an
ownership interest of approximately 7% in Concentra. The other investors own the
remaining   approximate   7%  interest.   We  accounted  for  the  merger  as  a
recapitalization  in which we did not affect the historical  basis of our assets
and liabilities and did not create any new goodwill related to the merger.


Financing of the Merger

     A total of approximately $1.1 billion was required to:

     o   pay the cash consideration to Concentra stockholders in the merger;

     o   repay indebtedness,  including the purchase of Concentra's  outstanding
         convertible subordinated notes; and

     o   pay related fees and expenses.

     The sources of funding for the transactions were:

     o   $80.9 million of cash from Concentra;

     o   drawings of $375.0 million under the senior credit facilities;

     o   net  proceeds  of $110.0  million  from the  issuance  of the  discount
         debentures;

     o   proceeds of $423.7 million from the equity contributions; and

     o   net proceeds of $190.0 million from the offering of the old notes.


Debt Tender Offers

     In connection  with the merger,  Concentra  conducted debt tender offers to
acquire all of its outstanding  convertible  subordinated notes and to eliminate
the  interest  expense  associated  with those notes.  Concentra  bought all but
$190,000 of the 6.0% convertible  subordinated notes and bought all but $100,000
of the 4.5% convertible  subordinated notes. We completed an offer to repurchase
the  outstanding  6.0%  convertible  subordinated  notes  and  4.5%  convertible
subordinated  notes not  previously  tendered and accepted for payment at $1,000
per $1,000  principal  amount plus accrued and unpaid  interest.  In that offer,
Concentra  bought all of the remaining 4.5% convertible  subordinated  notes and
bought all but $13,000 of the 6.0% convertible subordinated notes. The indenture
governing  the notes will  permit us to  distribute  funds to  Concentra  to pay
interest,  principal,  any premium and any  amounts due upon  conversion  of the
remaining $13,000 of 6.0% convertible subordinated notes.

                               THE EXCHANGE OFFER

Purpose of the Exchange Offer


     A registration rights agreement currently entitles the holders of old notes
to registration  rights. The registration  rights agreement obligates us to file
with the  Commission a  registration  statement  covering the offer by us to the
holders  of the old notes to  exchange  all of the old notes for the new  notes.
This  exchange  offer,  if  completed,  will satisfy our  obligations  under the
registration rights agreement.


Terms of the Exchange Offer

     Upon the terms and subject to the conditions  set forth in this  prospectus
and in the accompanying letter of transmittal, we will accept all notes properly
tendered  and not  withdrawn  prior to 5:00  p.m.,  New York City  time,  on the
expiration  date. We will issue $1,000 principal amount of new notes in exchange
for each $1,000  principal  amount of old notes accepted in the exchange  offer.
Holders may tender some or all of their notes under the exchange offer.


     Based on an  interpretation  by the  staff of the  Commission  set forth in
no-action  letters  issued to third  parties,  we believe that you may offer for
resale,  resell and  otherwise  transfer the new notes,  issued  pursuant to the
exchange  offer in exchange  for old notes,  unless you are a holder that is our
"affiliate" within the meaning of the Securities Act or you are a broker-dealer,
without compliance with the registration and prospectus  delivery  provisions of
the  Securities  Act,  provided that such new notes are acquired in the ordinary
course of business,  and you have no arrangement  with any person to participate
in the  distribution  of  such  new  notes.  See  Morgan  Stanley  & Co.,  Inc.,
Commission  No-Action  Letter  (available June 5, 1991),  Exxon Capital Holdings
Corporation,  Commission No-Action Letter (available May 13, 1988), and Shearman
& Sterling, Commission No-Action Letter (available July 2, 1993).

     If you  participate in the exchange offer for the purposes  of distributing
securities in a manner that the Commission  does not permit,  you could not rely
on the  position  of the  staff  of the  Commission  in Exxon  Capital  Holdings
Corporation  or similar  interpretive  letters  and could not resell  your notes
unless an exemption  from the  registration  provisions of the Securities Act is
available  for the  transfer  or you resell  your notes in  compliance  with the
registration and prospectus delivery requirements of the Securities Act.

     A broker-dealer  can only transfer new notes issued to a  broker-dealer  in
the exchange offer for the  broker-dealer's  own account which the broker-dealer
acquired as a result of market-making activities or other trading activities, if
the  broker-dealer  acknowledges  that it will deliver a prospectus  meeting the
requirements  of the Securities Act in connection  with any resale of new notes.
The letter of transmittal  states that by so  acknowledging  and by delivering a
prospectus,  the Commission will not deem a broker-dealer to admit that it is an
"underwriter"  within the meaning of the Securities Act. A broker-dealer may use
this prospectus, as we may amend the broker-dealer or supplement it from time to
time, in connection with resales of new notes. See "Plan of Distribution."

     Except as described  above no one may use this  prospectus  for an offer to
resell, resale or other transfer of new notes.

     We will not make the  exchange  offer to,  nor will we accept  tenders  for
exchange from,  holders of old notes in any  jurisdiction  in which the exchange
offer or the  acceptance of it would not comply with the  securities or blue sky
laws of that jurisdiction.


Terms of the Exchange Offer


     As of the date of this  prospectus,  there  was  $190.0  million  aggregate
principal  amount  of the  notes  outstanding.  We will  send  this  prospectus,
together with the letter of transmittal,  to all registered holders of old notes
as of the date of this prospectus.



                                       20
<PAGE>



     The exchange agent will deem that we accept validly tendered notes when, as
and if we give written notice of acceptance to the exchange agent.  The exchange
agent will act as agent for the tendering  holders of old notes for the purposes
of receiving  the new notes from us and  delivering  new notes to the  tendering
holders.

     If you do not tender your old notes, they will remain  outstanding and will
continue to accrue interest from their date of issue, August 17, 1999, at a rate
of 13% per annum.

     Except as noted below, in the event we consummate the exchange  offer,  the
registration  rights  agreement  will not require us to register  untendered old
notes.  In that event,  holders of notes seeking  liquidity in their  investment
would  have  to  rely on  exemptions  to  registration  requirements  under  the
securities  laws,   including  the  Securities  Act.  See  "Risk  Factors--Risks
Applicable to the Notes." The registration  rights agreement requires us to file
a shelf registration statement with the Commission if a holder of notes notifies
us that such holder is not allowed to participate in this exchange offer by law.


Expiration Date; Extensions


     The term  "expiration  date" means the expiration date on the cover page of
this  prospectus,  unless we, in our  discretion,  extend the exchange offer, in
which case the term  "expiration  date" means the latest date to which we extend
the exchange offer.


     In order to extend the  expiration  date, we will notify the exchange agent
of any extension by written notice and will make a public  announcement  of that
extension, each prior to 9:00 a.m., New York City time, on the next business day
after the previously  scheduled expiration date. The announcement may state that
we are extending the exchange offer for a specified period of time.

Procedures for Tendering


     Unless you make the tender in  book-entry  form,  to tender in the exchange
offer, a holder must  complete,  sign and date the letter of  transmittal,  or a
facsimile of it,

     o   have the signatures guaranteed if the letter of transmittal requires it
         and


     o   mail or otherwise  deliver the letter of  transmittal or the facsimile,
         the old notes and any other required  documents,  to the exchange agent
         prior to 5:00 p.m., New York City time, on the expiration date.


     We  refer  to the  Depository  Trust  Company  as the  DTC.  Any  financial
institution  that is a participant in The Depository  Trust Company's system may
cause DTC to  transfer  the old notes  into the  exchange  agent's  account.  In
connection with the delivery of old notes through  book-entry  transfer into the
exchange agent's account at DTC, you must transmit the letter of transmittal, or
facsimile,  with  any  required  signature  guarantees  and any  other  required
documents or an agent's message,  as described below, to the exchange agent. The
exchange  agent  must  also  receive  or  confirm  delivery  of  the  letter  of
transmittal  and any other  required  documents at its addresses set forth under
the caption "Exchange Agent," below,  prior to 5:00 p.m., New York City time, on
the  expiration  date.  Delivery  of  documents  to DTC in  accordance  with its
procedures does not constitute delivery to the exchange agent.

     To effectively tender notes through DTC, the financial  institution that is
a participant in DTC will  electronically  transmit its  acceptance  through the
Automatic Tender Offer Program. DTC will then edit and verify the acceptance and
send an  agent's  message to the  exchange  agent for its  acceptance.  The term
"agent's  message"  means a message  that DTC  transmits,  and that the exchange
agent  receives  and forms part of the  book-entry  confirmation.  That  message
states  that a  participant  in DTC  expressly  acknowledges  to DTC  that it is
tendering  old  notes  that  DTC  subjects  to  book-entry   confirmation.   The
participant  also  acknowledges  that the participant  received and agrees to be
bound by the  terms of the  applicable  letter of  transmittal;  and that we may
enforce that agreement against that participant.  The exchange agent will make a
request to  establish  an account  for the notes of DTC for the  purposes of the
exchange offer promptly after the date of this prospectus.


                                       21
<PAGE>


     The method of delivery of old notes and the letter of  transmittal  and all
other  required  documents to the exchange  agent is at the election and risk of
the  holders.  Instead of delivery by mail,  we  recommend  that  holders use an
overnight  or  hand  delivery  service.  In  all  cases,  holders  should  allow
sufficient  time to assure  delivery to the exchange agent before the expiration
date. You should not send your letter of transmittal of old notes to us. Holders
may request their respective brokers, dealers, commercial banks, trust companies
or nominees to effect the tenders for those holders.

     If a broker,  dealer,  commercial  bank,  trust  company  or other  nominee
registered your notes in its name and you wish to tender, you should contact the
registered  holder  promptly and instruct  that  registered  holder to tender on
behalf of the beneficial owner. If the beneficial owner wishes to tender on that
owner's own behalf, the owner must, prior to completing and executing the letter
of transmittal and delivery of such owner's old notes,  either make  appropriate
arrangements  to  register  ownership  of the old notes in the  owner's  name or
obtain a properly  completed bond power from the registered holder. The transfer
of registered ownership may take considerable time.

     An  eligible   institution  must guarantee  a  signature  on  a  letter  of
transmittal or a notice of  withdrawal,  unless you tender the old notes and you
are :

     o  a registered  holder who has not  completed  the box  entitled  "Special
        Issuance  Instructions" or "Special Delivery Instructions" on the letter
        of transmittal; or

     o  tendering  for the  account of an  eligible  institution,  as  described
        below.

     In the event  that we  require a  guarantee  of  signatures  on a letter of
transmittal  or a notice of  withdrawal an eligible  institution  must make that
guarantee.


     An  "eligible  institution"  is a  member  firm  of a  registered  national
securities exchange or of the National Association of Securities Dealers,  Inc.,
a commercial  bank or trust  company  having an office or  correspondent  in the
United  States or an eligible  guarantor  institution  within the meaning of the
Exchange Act,  which is a member of the  Securities  Transfer  Agents  Medallion
Program or the Stock Exchange Medallion Signature Program.


     If the  letter  of  transmittal  is  signed  by a  person  other  than  the
registered  holder of any old notes the  registered  holder must endorse the old
notes or a properly  completed bond power signed by the  registered  holder must
accompany the old notes.

     If  trustees,  executors,  administrators,   guardians,  attorneys-in-fact,
officers  of  corporations  or others  acting in a fiduciary  or  representative
capacity sign or endorse the letter of transmittal or bond powers, those persons
should so  indicate  when  signing,  and unless  waived by us,  submit  evidence
satisfactory to us of their authority to act in that capacity with the letter of
transmittal.


Guaranteed Delivery Procedures

     If you desire to accept the exchange offer, and

     o   certificates for the old notes are not immediately available;

     o   time  will not  permit a letter  of  transmittal  or notes to reach the
         exchange agent before the expiration date; or


     o   you cannot complete the procedure for book-entry  transfer  on a timely
         basis;

you may effect a tender if  the exchange agent has received at its addresses set
forth under the caption "Exchange Agent" below prior to 5:00 p.m., New York City
time, on the expiration date from an eligible  institution a properly  completed
and duly  executed  notice of  guaranteed  delivery,  substantially  in the form
provided by us, setting forth:



                                       22
<PAGE>


     o   the name and address of the registered holder;

     o   the certificate numbers of the old notes;

     o   the principal amount of the notes to be tendered;

     o   stating  that you are making the  tender by the  notice  of  guaranteed
         delivery; and

     o   guaranteeing  that  within  five  New York Stock  Exchange  trading the
         eligible  institution  will deliver days after the expiration  date the
         eligible  distribution will deliver,  the old notes, in proper form for
         transfer,  or a confirmation  of book-entry  transfer of the notes into
         the exchange agent's account at DTC, together with a properly completed
         and  duly  executed  letter  of  transmittal,  and any  other  required
         documents, or, if applicable,  an agent's message instead of the letter
         of transmittal.

     Unless you  deposit  old notes  that you  tendered  by the  above-described
method with the exchange  agent  within the time period set forth  above,  along
with a properly completed letter of transmittal and any other required documents
or, if applicable,  an agent's message instead of the letter of transmittal,  we
may, at our option, reject the tender.


Acceptance of Old Notes for Exchange

     The tender by a holder of old notes will constitute an agreement between us
and the holder in  accordance  with the terms and subject to the  conditions  in
this prospectus and in the letter of transmittal.


     We will  determine  all questions as to the  validity,  form,  eligibility,
including  time of receipt  and  acceptance  for  exchange  of any tender of old
notes, which  determination  will be final and binding.  We reserve the absolute
right to reject any or all  tenders  not in proper  form or the  acceptance  for
exchange of which may,  in the  opinion of our  counsel,  be  unlawful.  We also
reserve the absolute right to waive any defect or  irregularity in the tender of
any old notes. In addition,  we reserve the right to waive any of the conditions
of the exchange offer in our reasonable discretion.

     Our  interpretation  of the terms and  conditions  of the  exchange  offer,
including  the  instructions  in the  letter of  transmittal,  will be final and
binding,  on  all  parties.   Unless  waived,  you  must  cure  any  defects  or
irregularities  in connection  with tenders of old notes within a time period we
will  determine.  Although  we intend to request  the  exchange  agent to notify
holders of defects or irregularities  relating to tenders of old notes,  neither
we,  the  exchange  agent nor any other  person  will have any duty or incur any
liability  for  failure to give that  notification.  We will not  consider  your
tender  of old  notes  valid  until  you  cure  or we  waive  those  defects  or
irregularities.  Any old notes  received by the exchange  agent that you did not
properly tender and as to which you did not cure or we did not waive the defects
or  irregularities  will be  returned  by the  exchange  agent to the  tendering
holders,  unless  otherwise  provided in the letter of  transmittal,  as soon as
practicable following the expiration date.


     By tendering, you will represent to us that, among other things,


     o   you will obtain the new notes  acquired  pursuant to the exchange offer
         in the ordinary course of your business;


     o   you  have  no  arrangement  with  any  person  to  participate  in  the
         distribution of those new notes;

     o   you are not an "affiliate," as defined under the Securities Act, of us;
         and

     o   if you are a broker or a dealer,  as defined in the Exchange  Act, that
         you  acquired  the old  notes  for your  own  account  as a  result  of
         market-making  activities or other trading activities and that you will
         comply with the  registration and prospectus  delivery  requirements of
         the Securities Act.

Withdrawal of Tenders


     Except as otherwise  provided in this prospectus,  you may withdraw tenders
of old  notes at any time  prior  to 5:00  p.m.,  New  York  City  time,  on the
expiration date.

     To withdraw a tender of notes in the exchange  offer,  the  exchange  agent
must receive a written  transmission  notice of withdrawal via telegram,  telex,
facsimile  transmission  or letter at its  address  set forth  under the caption
"Exchange Agent" below prior to 5:00 p.m., New York City time, on the expiration
date. Any notice of withdrawal must:


     o   specify  the name of the person  having  deposited  the old notes to be
         withdrawn;


     o   identify the old  notes you are withdrawing, including the  certificate
         number or numbers and principal  amount of those notes, or, in the case
         of old notes transferred by book-entry transfer, the name and number of
         the account at DTC to be credited;


     o   be signed by the person having  deposited the old notes to be withdrawn
         in the  same  manner  as  the  original  signature  on  the  letter  of
         transmittal by which those notes were tendered,  including any required
         signature  guarantees,  or be  accompanied  by  documents  of  transfer
         sufficient  to have the trustee with respect to the old notes  register
         the transfer of such notes into the name of the person  having made the
         original tender and withdrawing the tender; and

     o   specify the name in which any notes are to be registered,  if different
         from that of the person having deposited the notes to be withdrawn.


     We will determine all questions as to the validity,  form and  eligibility,
including time of receipt,  of withdrawal notices which  determination  shall be
final and binding on all parties.  We will deem as not validly  tendered any old
notes you  withdraw  , and we will not issue  new notes to you with  respect  to
withdrawn old notes unless the old notes so withdrawn are validly retendered. We
will  return to you any old notes  that you tender but that we do not accept for
exchange  as soon as  practicable  after  withdrawal,  rejection  of  tender  or
termination of the exchange offer. We may return properly withdrawn old notes by
following one of the procedures described above under "Procedures for Tendering"
at any time prior to the expiration date.


Conditions

     The  exchange  offer is not subject to any  conditions  other than that the
exchange offer does not violate applicable law or any applicable  interpretation
of the staff of the Commission.

Accounting Treatment


     We will record the new notes at the same carrying value as the old notes as
reflected in our accounting records on the date of the exchange. Accordingly, we
will not recognize any gain or loss for accounting  purposes upon the completion
of the exchange  offer. We will capitalize and amortize over the term of the new
notes any expenses of the exchange offer that we paid.


Exchange Agent


     We appointed  United States Trust Company of New York as exchange agent for
the exchange offer.  You should direct questions and requests for assistance and
requests for additional copies of this prospectus or of the letter of transmital
and deliveries of completed  letters of  transmittal  with tendered old notes to
the exchange agent addressed as follows:

                 SELECTED CONSOLIDATED HISTORICAL FINANCIAL DATA

     The table below presents  consolidated  historical financial data that have
been derived from  Concentra's  audited  consolidated  financial  statements and
Concentra Operating's unaudited  consolidated  financial statements.  You should
read the selected  financial data in conjunction  with Concentra's and Concentra
Operating's separate historical consolidated financial statements, related notes
and other financial information found elsewhere in this prospectus.

     The accompanying  consolidated financial statements as of December 31, 1998
and  September  30, 1999 and for the three and nine months ended  September  30,
1998 and 1999 and related  footnotes  reflect the operating results of Concentra
through  August 17, 1999 and the operating  results of Concentra  Operating from
August  18,  1999  through  September  30,  1999.   Concentra   Operating  is  a
wholly-owned  subsidiary of Concentra  and they are  considered  entities  under
common control,  therefore,  combined financial  statements have been presented.
Earnings per share has not been reported for all periods presented, as Concentra
Operating is a  wholly-owned  subsidiary  of Concentra  and has no publicly held
shares.

1)   Concentra recorded the following  non-recurring  charges: (a) $38.6 million
     in the  third  quarter  of  1997  primarily  related  to the  formation  of
     Concentra by the merger of CRA Managed Care,  Inc. and  OccuSystems,  Inc.;
     (b) $12.6  million in the first  quarter of 1998  primarily  related to the
     merger with  Preferred  Payment  Systems,  Inc.;  (c) $20.5  million in the
     fourth  quarter  of 1998  primarily  related to the  reorganization  of the
     Managed Care Services division and charges related to the recognition of an
     impairment loss on the intangible  related to an acquired  contract and (d)
     $54.4 million in the third quarter of 1999 primarily for fees, expenses and
     other non-recurring charges associated with the merger.

(2)  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 $3.8 million in the first
     quarter of 1994.  Concentra's pro forma net income for 1994 would have been
     $3.4 million  higher had CRA 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.

(3)  As a result of Concentra going private in the merger transaction, there are
     no longer  publicly held shares  outstanding and we believe that historical
     earnings per share information is not meaningful.

(4)  The ratio of earnings to fixed  charges is computed by dividing  the sum of
     net  earnings,  before  deducting  provisions  for  income  taxes and fixed
     charges,  and  adjusted  for  the  equity  in  earnings  of  unconsolidated
     subsidiaries  and related  distributions,  by fixed charges.  Fixed charges
     consist of interest on debt, including amortization of debt issuance costs,
     and one-fourth of rent expenses, estimated by management to be the interest
     component of such  rentals.  The ratio of earnings to fixed  charges is not
     adequate to cover fixed  charges for the pro forma year ended  December 31,
     1998 and the nine month and pro forma nine month  periods  ended  September
     30, 1999, by $5.2 million, $14.7 million, and $43.2 million, respectively.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The  following  discussion  should be read  together with the more detailed
information in the historical consolidated financial statements of Concentra and
Concentra Operating, including the related notes thereto, appearing elsewhere in
this prospectus.

Recapitalization Transaction

     On August 17, 1999,  Concentra merged with Yankee, a corporation  formed by
Welsh  Carson,  a 14.9%  stockholder  of  Concentra.  As a result of the merger,
41,056,966  shares of Concentra  common stock were converted to $16.50 per share
in cash. The remaining 6,343,203 shares held by Yankee were not converted. Welsh
Carson  acquired  approximately  86%, funds managed by Ferrer  Freeman  acquired
approximately  7%  and  other  investors   acquired   approximately  7%  of  the
post-merger  shares of common stock of Concentra,  Concentra  Operating's parent
company,  for $16.50 per share.  Simultaneous with the right to receive cash for
shares,  Yankee merged with and into Concentra and Concentra  contributed all of
its operating  assets and liabilities  with the exception of $110,000,000 of 14%
Senior  Discount   Debentures  due  2010  and  $327,750,000  of  6.0%  and  4.5%
Convertible Subordinated Notes to Concentra Operating, a wholly-owned subsidiary
of  Concentra.   The  6.0%  and  4.5%   Convertible   Subordinated   Notes  were
substantially  retired during the quarter as a result of the merger.  The merger
was  accounted  for as a  recapitalization  transaction,  with no changes to the
basis of  assets or  liabilities.  Following  Concentra's  merger  with  Yankee,
Concentra  contributed  all of  its  assets  and  shares  in  its  subsidiaries,
including  Concentra Health Services,  Inc. and Concentra Managed Care Services,
Inc., to Concentra Operating, a wholly owned subsidiary of Concentra.

     The merger transaction was valued at approximately $1.2 billion,  including
the refinancing of $327.8 million of the 6.0% and 4.5% convertible  subordinated
notes that were  tendered  during the  quarter.  To finance the  acquisition  of
Concentra  Welsh  Carson,  Ferrer  Freeman  and  the  other  investors  invested
approximately $423.7 million in equity financing,  including the value of shares
already  owned by Welsh  Carson,  and  $110.0  million  of 14%  senior  discount
debentures due 2010 with warrants issued by Concentra exercisable for its common
shares. Concentra Operating received from various lenders $375.0 million in term
loans,  a $100.0  million  revolving  credit  facility to replace the pre-merger
revolving credit facility and $190.0 million of 13% series A senior subordinated
notes due 2009.  Concentra's  excess cash  balances  funded merger and financing
related fees and  expenses  and related  employee  stock  option  exercises  and
cancellation payments.

     Concentra  incurred  $18.0  million  of  deferred  financing  fees  for the
issuance of the merger related financing and recorded a non-recurring  charge of
$54.4 million in the third quarter of 1999 incurred primarily for fees, expenses
and  other   non-recurring   charges   associated  with  the  merger.   Of  this
non-recurring  charge,  approximately  $16.4 million for  professional  fees and
services,  $13.5  million  for  employee  related  stock  option  exercises  and
cancellations, $10.5 million for a Welsh Carson transaction fee and $2.4 million
of other  non-recurring  charges was paid and  $5.5 million of non-cash  charges
for  deferred  compensation  expense  related  to the  accelerated  vesting  and
issuance of 210,000  shares of restricted  stock was used through  September 30,
1999. At September  30, 1999,  approximately  $6.1 million of the  non-recurring
charge remains for professional fees and services, employee related stock option
exercises and other non-recurring charges.


Overview

     Concentra was formed on August 29, 1997 through the merger of  OccuSystems,
Inc.  and CRA Managed  Care,  Inc.  That  merger was a tax-free  stock for stock
exchange accounted for as a  pooling-of-interests.  Following Concentra's merger
with  Yankee,  Concentra  contributed  all  of  its  assets  and  shares  in its
subsidiaries,  including  Concentra Health Services,  Inc. and Concentra Managed
Care  Services,  Inc.,  to Concentra  Operating,  a wholly owned  subsidiary  of
Concentra.

     Throughout this prospectus,  we refer to Concentra Health Services, Inc. as
Health  Services  and  Concentra  Managed  Care  Services,  Inc. as Managed Care
Services.  The following  represents a discussion and analysis of the operations
of Concentra.

     Through Health Services we manage occupational  healthcare centers at which
we provide  support  personnel,  marketing,  information  systems and management
services to our affiliated  physicians.  Health Services, and the joint ventures
which  Health  Services  controls,  own  all  of  the  operating  assets  of our
occupational  healthcare  centers,  including  leasehold  interests  and medical
equipment.  At our centers,  we generate 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 nine months ended September
30, 1998 and 1999,  Health Services  derived 63.2% and 63.7% of its net revenues
from the treatment of  work-related  injuries and illnesses,  respectively,  and
36.8% and 36.3% of its net revenues from non-injury  related  medical  services,
respectively.  For the years ended  December  31,  1996,  1997 and 1998,  Health
Services  derived 63.8%,  63.5% and 63.1% of its net revenues from the treatment
of work-related injuries and illnesses, respectively, and 36.2%, 36.5% and 36.9%
of its net revenues from non-injury related medical services, respectively.

     Physician and physical  therapy  services are provided at our centers under
management agreements with affiliated physician associations. These associations
or groups are organized professional  corporations that hire licensed physicians
and physical  therapists to provide medical  services to our centers'  patients.
Health  Services  has a nominee  shareholder  relationship  with  each  group as
defined in EITF 97-2,  "Application of APB Opinion No. 16 and FASB Statement No.
94 to Physician Practice Entities", and as a result, the financial statements of
each affiliated physician group are consolidated. Specifically:

     o   Health  Services  can at all times  establish  or effect  change in the
         nominee shareholder;

     o   Health  Services  can  cause a change  in the  nominee  shareholder  an
         unlimited number of times;

     o   Health  Services  has sole  discretion  without  cause to  establish or
         change the nominee shareholder;

     o   Health  Services  and each  physician  group would incur no more than a
         nominal cost to cause a change in the nominee shareholder; and

     o   neither  Health  Services nor the  physician  groups are subject to any
         significant adverse impact upon a change in the nominee shareholder.



                                       29
<PAGE>

     The management  fees we collect from each physician group are calculated as
collected  revenue net of compensation,  benefits and other expenses incurred by
the groups.

     Through Managed Care Services we provide  specialized  cost containment and
field case management services designed to reduce costs associated with workers'
compensation, disability and automobile accident coverage. Managed Care Services
earns most of its revenues on a fee-for-service or percentage-of-savings  basis.
The specialized cost containment services we provide include our:

     o   first-report-of-injury,  utilization  management,  precertification and
         concurrent review;

     o   retrospective medical bill review;

     o   telephonic case management;

     o   preferred provider  organizations,  or preferred provider  organization
         network access;

     o   independent medical examinations;

     o   peer reviews; and

     o   out-of-network bill review services.

     We have designed  each service to reduce the cost of workers'  compensation
claims, automobile accident injury claims and group health claims.

     On February 24, 1998, we merged Concentra  Subsidiary,  Inc. with Preferred
Payment  Systems,  Inc.  in  a  pooling-of-interests  transaction.  This  merger
significantly  expanded  our  presence in the  out-of-network  group health bill
review market.  Preferred Payment Systems,  now operating as Concentra Preferred
Systems,  Inc., is a nationwide  provider of specialized  cost  containment  and
outsourcing  services for  healthcare  payors.  In the first quarter of 1998, we
recorded a non-recurring  charge of $12.6 million primarily  associated with our
merger with Preferred  Payment  Systems.  Managed Care Services has  experienced
significant growth in its specialized cost containment services by virtue of the
acquisitions of:

     o   Focus Healthcare Management, Inc. on April 2, 1996;

     o   Prompt Associates, Inc. on October 29, 1996;

     o   First Notice Systems, Inc. on June 4, 1997;

     o   About  Health,   Inc.  by  Preferred  Payment  Systems  in  a  two-step
         transaction on August 1, 1997 and October 31, 1997; and

     o   other smaller acquisitions.

     Our field case management  services  involve working on a one-on-one  basis
with injured employees and their various healthcare professionals, employers and
insurance  company  adjusters to assist in maximizing  medical  improvement and,
where  appropriate,  to expedite their return to work. Our field case management
gross profit margins  deteriorated in the second half of 1998 and we reorganized
field case management services in the fourth quarter of 1998. The reorganization
was designed to improve efficiency  through facility  consolidations and related
headcount  reductions.  In  connection  with our  reorganization,  we recorded a
non-recurring  charge of $20.5 million related to the  reorganization,  settling
claims on six  expired  contracts  and for the  write-off  of assets,  including
customer lists, the value of the trained workforce and furniture and fixtures we
acquired  from  an  insurance  carrier  associated  with  a  contract  which  we
subsequently determined to be unprofitable.  We believe that the current size of
our field case management office network is sufficient to serve the needs of our
nationwide  customers.  As a result, we anticipate  opening only a few new field
case management offices per year if client needs in selected regions require it.
We would,  however,  examine the possibility of acquiring  additional field case
management offices or businesses if an appropriate strategic opportunity were to
arise.

Results of Operations for the Three and Nine Months Ended September 30, 1998 and
1999

Revenues

     Our total revenues  increased  12.3% in the third quarter of 1999 to $176.7
million  from  $157.4  million in the third  quarter of 1998.  Health  Services'
revenues  increased  29.1% in the third  quarter of 1999 to $89.9  million  from
$69.6  million in the third  quarter of 1998.  Managed Care  Services'  revenues
decreased 1.1% in the third quarter of 1999 to $86.8 million as specialized cost
containment  revenues  increased  11.0% for the third  quarter  of 1999 to $50.7
million  from  $45.7  million  in the  third  quarter  of 1998  and  field  case
management  revenues  decreased  14.2%  in the  third  quarter  of 1999 to $36.1
million from $42.1 million in the third quarter of 1998.

     Our total  revenues  increased  10.2% for the nine months of 1999 to $506.2
million  from  $459.1  million  for the nine  months of 1998.  Health  Services'
revenues  increased  25.2% for the nine  months of 1999 to $242.4  million  from
$193.7  million for the nine months of 1998.  Managed  Care  Services'  revenues
decreased 0.6% for the nine months of 1999 to $263.7 million as specialized cost
containment  revenues  increased  10.5%  for the nine  months  of 1999 to $151.6
million  from  $137.2  million  for the  nine  months  of 1998  and  field  case
management  revenues  decreased  12.6%  for the nine  months  of 1999 to  $112.1
million from $128.3 million for the nine months of 1998.

     Health Services' revenue growth resulted  primarily from the acquisition of
practices and an increase of business in existing markets.

     The increase in  specialized  cost  containment  revenue  growth is largely
attributable to:

     o   our growth in out-of-network bill review services;

     o   preferred provider organization network access fees;


                                       31
<PAGE>


     o   first report of injury; and

     o   telephonic case management services in existing locations.

     The decrease in field case management revenue is primarily  attributable to
a  reorganization  of the  division  in the  fourth  quarter  of 1998 to improve
efficiency through facility  consolidations and related headcount reductions and
the related  transition  of the field case  management  business.  Prior to this
transition,  the field case  management  business  was  handled on a "full" case
management  approach,  where all tasks were bundled as a single  package.  In an
effort to increase  efficiency  and better  service its customer base, the field
case  management  business  converted  to a  "task-based"  approach,  where  the
customer  selects the specific tasks field case  management  performs.  This new
approach has caused a reduction  in the billable  hours per case and has thereby
decreased field case management  revenue.  We anticipate billable hours per case
will  continue to decrease with the  continued  transition  to the  "task-based"
approach,  but that this decrease and its corresponding  decrease in revenue may
be somewhat mitigated or overcome by increases in case volume as demand for this
new approach increases.

     Our total  contractual  allowances,  related  to the  Concentra  Health and
Concentra  Preferred  Business  System,  offset against revenues during the nine
months ended  September 30, 1998 and 1999 were $12.2 million and $18.1  million,
respectively.

Cost of Services

     Our total cost of services  increased 17.1% in the third quarter of 1999 to
$139.0  million  from  $118.7  million  in the  third  quarter  of 1998.  Health
Services'  cost of sales  increased  39.4% in the third quarter of 1999 to $71.4
million  from $51.2  million in the third  quarter  of 1998 while  Managed  Care
Services' cost of services  increased 0.2% in the third quarter of 1999 to $67.6
million from $67.5 million in the third quarter of 1998.

     Our total cost of services  increased  13.8% for the nine months of 1999 to
$392.9 million from $345.2 million for the nine months of 1998. Health Services'
cost of sales increased 32.1% for the nine months of 1999 to $191.8 million from
$145.2  million for the nine months of 1998 while Managed Care Services' cost of
services  increased  0.6% for the nine  months  of 1999 to $201.2  million  from
$200.0 million for the nine months of 1998.

     Our total gross profit  margin  decreased to 21.3% in the third  quarter of
1999  compared to 24.6% in the third  quarter of 1998.  Health  Services'  gross
profit margin  decreased to 20.6% in the third quarter of 1999 compared to 26.4%
in the third  quarter of 1998 while Managed Care  Services'  gross profit margin
decreased to 22.1% in the third  quarter of 1999  compared to 23.1% in the third
quarter of 1998.

     Our total gross profit margin  decreased to 22.4% for the first nine months
of 1999  compared  to 24.8% for the first nine months of 1998.  Health  Services
gross  profit  margin  decreased  to 20.9%  for the  first  nine  months of 1999
compared to 25.0% for the first nine months of 1998 while Managed Care Services'
gross  profit  margin  decreased  to 23.7%  for the  first  nine  months of 1999
compared to 24.7% for the first nine months of 1998.

     Health Services' gross profit margin decreased primarily as a result of:

     o   lower same  market  revenue  growth  during the quarter and nine months
         ended September 30, 1999 than we expected, from 11.5% last year to 8.0%
         this year, due to a decrease in visits for existing locations, or visit
         growth,  while expenses at those locations increased in anticipation of
         traditional increases;

     o   an acceleration in the roll-out of patient tracking and billing systems
         into the medical  centers,  which  resulted in additional  depreciation
         related to those systems this year over last year;

     o   the  impact of lower  margins  from  practices  recently  acquired  and
         developed.

                                       32
<PAGE>


     The decrease in visit growth may be attributable to:

     o   decreases in national injury trends;

     o   weather; and

     o   other operational considerations attributable to the quarter.


     We anticipate  that same market  revenue  growth will  stabilize at current
levels. In addition, we anticipate that same market expense growth will decrease
to the same market revenue growth rate of 8%.


     Health  Services has also  incurred  start-up  losses during the quarter of
approximately  $1.9 million related to the newly  established drug screening lab
in Memphis,  TN and the  acquisition of recently  developed  medical  centers in
several new markets.  Historically,  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' gross profit margins  decreased in the third quarter
and  first  nine  months  of 1999 due  primarily  to a  slowdown  in field  case
management  revenue  and a decrease in  provider  bill review and claims  review
gross  profit  margins  partially  offset by an  increase  in  specialized  cost
containment  services  revenue  which has  historically  had higher gross profit
margins than field case management.


     Provider bill review gross profit margins decreased primarily due to:

     o   pricing concessions made in the second half of 1998;

     o   an  increase  of  approximately  $820,000,  primarily  related  to  the
         provision for billing adjustments as a result of our experience related
         to the billing and collection of revenue; and


     o   an increase in software  maintenance fees associated with a third party
         software supplier.



We expect the gross  profit  margin for  provider  bill review to continue to be
negatively  affected for the  remainder of 1999 versus 1998 due to the impact of
pricing  concessions  made in the second  half of 1998 and due to an increase in
software  maintenance fees associated with a third party software  supplier.  We
continue to review  procedures and systems for provider bill review  services to
identify and resolve  small  variances in customer  payment.  We also  regularly
review the status of accounts  receivable  and adjust our reserves as necessary.
We do not anticipate that these adjustments will have a material negative impact
on future gross profit margins or liquidity.



General and Administrative Expenses

     General and administrative expenses increased 34.6% in the third quarter of
1999 to $16.0  million from $11.9  million in the third quarter of 1998, or 9.0%
and 7.5% as a  percentage  of  revenue  for the third  quarter of 1999 and 1998,
respectively.  General and administrative expenses increased 40.0% for the first
nine  months of 1999 to $47.2  million  from  $33.7  million  for the first nine
months of 1998,  or 9.3% and 7.3% as a percentage  of revenue for the first nine
months  of  1999  and  1998,   respectively.   The   increases  in  general  and
administrative expenses in 1999 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 62.9% in the third quarter of 1999 to
$3.3 million from $2.1 million in the third quarter of 1998, or 1.9% and 1.3% as
a percentage  of revenue for the third  quarter of 1999 and 1998,  respectively.
Amortization of intangibles  increased 55.6% for the nine months of 1999 to $9.5
million  from $6.1  million for the nine  months of 1998,  or 1.9% and 1.3% as a
percentage  of revenue for the nine months of 1999 and 1998,  respectively.  The
increase is primarily  the result of a  prospective  change in the  amortization
period of goodwill and the amortization of additional  intangible assets such as
goodwill,  customer lists and assembled  workforces  primarily  associated  with
acquisitions by Health Services.

                                       33
<PAGE>

     We have historically  amortized goodwill over periods ranging from 30 to 40
years. Effective January 1, 1999, we changed our policy, on a prospective basis,
with respect to the  amortization of goodwill.  All existing and future goodwill
will be  amortized  over a period not to exceed 25 years.  Had we  adopted  this
policy at the  beginning  of 1998,  amortization  for the three and nine  months
ended  September  30, 1998 and for the year ended  December  31, 1998 would have
increased   approximately   $0.8   million,   $2.4  million  and  $3.3  million,
respectively.  As of September 30, 1999, net intangible  assets consisted of the
following (amounts in thousands):

Non-Recurring Charge

     In the first quarter of 1998, we recorded a  non-recurring  charge of $12.6
million  primarily  associated  with the merger of  Preferred  Payment  Systems.
Through  September  30,  1999,  we  had  paid  approximately  $5.3  million  for
professional fees and services,  $2.6 million in costs associated with personnel
reductions,  $1.1 million in facility consolidations and closings,  specifically
the  payment of lease  obligations  related to these  facilities,  $1.6  million
associated  with the write-off of deferred  financing fees on Preferred  Payment
Systems  indebtedness  retired and $1.5 million of other non-recurring costs. At
September  30,  1999,  approximately  $0.5 million of the  non-recurring  charge
remains primarily related to remaining  facility lease  obligations,  with terms
expiring through March 2003.

     In the fourth quarter of 1998, we recorded a non-recurring  charge of $20.5
million  primarily  associated  with  the  reorganization  of our  Managed  Care
Services  division to improve  efficiency  through facility  consolidations  and
related headcount reductions. The charge related to the reorganization, settling
claims on six expired contracts and the write-off of assets,  including customer
lists,  the value of the  trained  work  force and  furniture  and  fixtures  we
acquired  from  an  insurance  carrier  associated  with  a  contract  which  we
subsequently  determined to be unprofitable.  Through  September 30, 1999 we had
incurred  approximately  $7.4  million in charges  for the  write-off  of assets
related to the acquired  contract and paid $3.9 million in costs associated with
personnel  reductions,  $0.4 million in costs associated with settling claims on
other  expired  contracts,  $2.8  million in  facility  consolidations  and $0.1
million of other non-recurring costs. At September 30, 1999,  approximately $5.9
million of the  non-recurring  charge  remains  primarily  related to  remaining
facility lease obligations, with terms expiring through November 2003, and costs
associated with settling claims on other expired contracts.


     In the third quarter of 1999, we recorded a  non-recurring  charge of $54.4
million primarily for fees, expenses and other non-recurring  charges associated
with the merger.  Through  September 30, 1999, we had paid  approximately  $16.4
million for  professional  fees and services,  including  legal,  accounting and
regulatory  fees,  $13.5 million for employee related stock option exercises and
cancellations, $10.5 million for a Welsh Carson transaction fee for advisory and
consulting  services  provided to us in  connection  with the merger and related
financing,  and  $2.4  million  of  other  non-recurring  charges  and  incurred
approximately $5.5 million in non-cash charges for deferred compensation expense
related to the accelerated  vesting and issuance of 210,000 shares of restricted
stock. At September 30, 1999,  approximately  $6.1 million of the  non-recurring
charge remains for professional fees and services, employee related stock option
exercises and other  non-recurring  charges.  We  anticipate  that a significant
majority of this remaining charge will be used over the next 12 months.


Interest Expense

     Interest  expense  increased  $5.6 million in the third  quarter of 1999 to
$10.2 million from $4.7 million in the third quarter of 1998 and increased  $6.5
million for the first nine months of 1999 to $19.6 million from $13.1 million in
the first nine months of 1998 due primarily to increased outstanding  borrowings
from the  issuance of $565.0  million in merger  related  financing  with annual
interest  rates  ranging  from  8.5%  to  13.0%  offset  by  the  retirement  of
substantially  all of the  $327.8  million  of the  6.0%  and  4.5%  convertible
subordinated notes.


                                       34

Interest Income

     Interest income decreased $0.7 million in the third quarter of 1999 to $0.6
million  from $1.3  million  in the third  quarter  of 1998 and  decreased  $0.2
million for the first nine months of 1999 to $2.7  million from $2.9 million for
the first nine months of 1998 primarily as a result of excess cash being used to
complete the merger  transaction and to pay related fees and expenses.  The $0.2
million decrease in interest income for the first nine months of 1999 versus the
first nine months of 1998 is partially  offset by the increase in our investment
of excess cash as a result of the net proceeds of $223.6  million from the March
and April 1998  issuance of the 4.5%  convertible  subordinated  notes after the
payment of  approximately  $122.0  million of outstanding  borrowings  under the
senior  credit  facility,  debt  assumed in the merger  with  Preferred  Payment
Systems and the payment to Preferred Payment Systems dissenting shareholders.

Other, net

     Other income  increased  $0.4 million in the third  quarter of 1999 to $0.4
million from $21,000 in the third quarter of 1998 and increased $0.2 million for
the first nine months of 1999 to $0.1 million from other expense of $0.1 million
for the first nine  months of 1998.  Other  income and  expense,  net  primarily
relates to minority interests.

Provision for Income Taxes

     We  recorded  a tax  benefit of $3.2  million in the third  quarter of 1999
versus a tax  provision  of $9.0  million  in the  third  quarter  of 1998.  The
effective  tax rate was 7.0% and 42.0% in the third  quarters  of 1999 and 1998,
respectively.  We recorded a tax  provision  of $9.8  million for the first nine
months of 1999 versus a tax provision of $23.8 million for the first nine months
of 1998.  The effective tax rate was (67.1%) and 46.4% for the first nine months
of 1999 and 1998,  respectively.  Excluding the tax effects of the non-recurring
charges,  the  effective  tax rate would have been 58.4% and 42.0% for the third
quarters of 1999 and 1998, respectively,  and 46.2% and 42.0% for the first nine
months of 1999 and 1998,  respectively.  The above  disparities in the effective
tax rates excluding the tax effects of the  non-recurring  charges is the result
of the impact of the  non-deductibility  of certain fees and expenses associated
with the merger in 1999 and the  Preferred  Payment  Systems  merger in 1998. We
expect  to  continue  to  provide  for  taxes  at  an  effective   tax  rate  of
approximately  46% for the  remainder  of the year as the  increase  in interest
expense and goodwill  amortization from the change in the amortization period to
25 years in 1999 versus 30 to 40 years in 1998 results in lower pre-tax earnings
while expense items not deductible for tax,  goodwill and  non-deductible  meals
and entertainment, result in a higher tax provision.

Results of Operations for the Years Ended December 31, 1998 and 1997

Revenues

     Our total  revenues  increased  24.9% in 1998 to $611.1 million from $489.3
million in 1997.  Health  Services'  revenues  increased 24.9% in 1998 to $259.5
million from $207.7 million in 1997.  Managed Care Services'  revenues increased
24.8% in 1998 to $351.6 million from $281.6 million in 1997, as our  specialized
cost containment  revenues increased 28.6% in 1998 to $183.7 million from $142.9
million in 1997 and our field case management  revenues  increased 21.0% in 1998
to $167.8 million from $138.7 million in 1997.

     Health Services' revenue growth was due to:

     o   our acquisition of 16 occupational healthcare centers;

     o   our management of an additional four  occupational  healthcare  centers
         pursuant to a  management  contract  acquired in the fourth  quarter of
         1997;

     o   an increase in business in our existing markets;

     o   development of sites in new markets; and

     o   an increase in our consulting and other ancillary services.

                                       35
<PAGE>

     Managed Care  Services'  specialized  cost  containment  revenue  growth is
largely attributable to:

     o   the growth of Preferred  Payment  Systems  through its  acquisition  of
         About Health, First Notice Systems and other immaterial entities; and

     o   the  growth in  retrospective  medical  bill  review,  telephonic  case
         management  and  claims  reviews   services  in  our  existing  service
         locations.

     Managed Care Services'  field case  management  revenue growth is primarily
due to the business we generated from two field case management acquisitions and
the continued growth in revenues from our existing service locations.

     Our total  contractual  allowances offset against revenues during the years
ended  December  31,  1998  and 1997  were  $16.1  million  and  $14.7  million,
respectively.

Cost of Services

     Our total cost of  services  increased  25.9% 1998 to $469.3  million  from
$372.6 million in 1997.  Health  Services' cost of services  increased  29.5% in
1998 to $201.2 million from $155.4 million in 1997, while Managed Care Services'
cost of services  increased  23.4% in 1998 to $268.1 million from $217.3 million
in 1997.

     Our total gross profit margins decreased slightly to 23.2% in 1998 compared
to 23.8% in 1997.  Health  Services' gross profit margins  decreased to 22.5% in
1998  compared to 25.2% 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 principally because of:

     o   an acceleration in the roll-out of patient tracking and billing systems
         into our occupational healthcare centers;

     o   increased spending on marketing and facility improvements; and

     o   the  impact of lower  gross  profit  margins  from  practices  recently
         acquired and developed.

     Historically, as we consolidate certain functions, make other staff-related
changes, plus experience an increase in patient volume, the gross profit margins
of our acquired or developed practices have tended to improve.

     Managed  Care  Services  has  seen  improvement  in  gross  profit  margins
primarily  because  of a shift  in its  revenue  mix  towards  specialized  cost
containment  services,  including  the services  provided by  Preferred  Payment
Systems,  About Health and First Notice  Systems.  Revenues from these  services
have  historically  had higher gross profit  margins than revenues  derived from
field case management.  Although 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  uncollectible  accounts  receivable
charges. We expect the gross profit margins for provider bill review to continue
to be affected  negatively for the first half of 1999 compared to the first half
of 1998 due to the impact of pricing concessions made in the second half of 1998
and a higher level of bad debt provision.

General and Administrative Expenses

     Our general and  administrative  expenses  increased 13.8% in 1998 to $45.3
million from $39.8  million 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  were  due  primarily  to  the  continued  investment  in our
Information   Services  and   Technology   Group  and  in  our   accounting  and
administrative personnel.

Amortization of Intangibles

     Our  amortization  of intangibles  increased  37.4% in 1998 to $8.1 million
from $5.9 million 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:

     o   goodwill;

     o   customer lists and assembled  workforces  primarily associated with the
         purchases of First Notice Systems and About Health by Preferred Payment
         Systems;

     o   certain occupational healthcare centers from Vencor, Inc.; and

     o   various smaller acquisitions by Health Services.


Non-recurring Charge

     We recorded non-recurring charges for the years ended December 31, 1997 and
1998 of $38.6 million and $33.1 million, respectively.

     In the first quarter of 1998, we recorded a  non-recurring  charge of $12.6
million because of our merger of Preferred  Payment Systems.  The utilization of
this charge through December 31, 1998, was approximately:

     o   $5.1 million for professional fees and services;

     o   $2.4 million in costs associated with personnel reductions;

     o   $0.7 million in facility consolidations and closings;

     o   $1.6 million  associated with the write-off of deferred  financing fees
         on Preferred Payment; and

     o   $1.3 million of other non-recurring costs.

     At December  31,  1998,  approximately  $1.5  million of the  non-recurring
charge remains primarily related to remaining facility lease obligations.

     In the fourth quarter of 1998, we recorded a non-recurring  charge of $20.5
million primarily  associated with our  reorganization of Managed Care Services.
The utilization of this charge through December 31, 1998 was approximately:

     o   $7.4 million in charges  related to the  recognition  of an  impairment
         loss on the intangible related to an acquired contract;

     o   $2.5 million in costs associated with personnel reductions; and

     o   $1.1 million in facility consolidations.

     At December  31,  1998,  approximately  $9.5  million of the  non-recurring
charge remains  primarily  related to remaining  facility lease  obligations and
costs associated with settling claims on other expired contracts.

     Our  reorganization  plan for Managed Care  Services,  including  headcount
reductions and facility  consolidations,  was developed  between early September
and the end of October  1998.  We carried  out the  reorganization  plan in late
October and early  November 1998 with the headcount  reductions of 168 employees
completed and most of the facility  consolidations  completed or underway in the
fourth quarter of 1998.  The  restructuring  plan has not changed  significantly
from our original  estimate since most of the actions were completed or underway
by December 31, 1998. We

                                       37
<PAGE>

are realizing savings of approximately $2.4 million per quarter in personnel and
facility related expenses and have not experienced any significant interruptions
in our operations as a result of the restructuring.

     In the third quarter of 1997, we recorded a  non-recurring  charge of $38.6
million  associated  with the merger of CRA and  OccuSystems.  We finalized  our
merger and  transition  plan  during the third  quarter of 1997 with much of the
detailed  planning  occurring in August and September 1997,  prior to the end of
the quarter. The merger and transition plan was approved by senior management in
September 1997 and we identified all significant actions to be taken,  including
reductions in  duplicative  personnel.  The  utilization  of this charge through
December 31, 1998, was approximately:

     o   $11.6 million for professional fees and services;

     o   $16.2 million in costs  associated  with  personnel  reductions and the
         consolidation of CRA's and OccuSystems' employee benefits;

     o   $5.9 million in facility consolidations and closings;

     o   $2.5 million for the write-off of start-up costs; and

     o   $2.4 million of other charges.

     We expect to expend  approximately $8.4 million over the next twelve months
relating  to  the  first  quarter  of  1998  and  the  fourth  quarter  of  1998
non-recurring charges, consisting of approximately:

     o   $1.8 million of severance related costs;

     o   $3.2 million of facility related costs;

     o   $3.0  million  of  cost  associated  with  setting  claims  on  expired
         contracts; and

     o   $0.4 million of other costs.


Interest Expense

     Our interest  expense  increased $5.4 million in 1998 to $18.0 million from
$12.7 million in 1997 due primarily to our higher  outstanding  borrowings under
our existing credit  facilities to finance  acquisitions and the issuance of our
4.5% convertible subordinated notes, offset by the repayment of borrowings under
our  existing  credit  facility  and debt  assumed in our merger with  Preferred
Payment Systems.

Interest Income

     Our  interest  income  increased  $2.4 million in 1998 to $4.7 million from
$2.3 million in 1997 due  principally  the increase in our  investment of excess
cash as a result of the  receipt  of $223.6  million  in net  proceeds  from the
issuance of our 4.5% convertible subordinated notes after the payment of:

     o   approximately  $122.0  million  of  outstanding  borrowings  under  our
         existing credit facility;

     o   debt assumed in the merger of Preferred Payment Systems; and

     o   the payment to Preferred Payment Systems dissenting shareholders.


Other Expense, Net

     Our other expense, net primarily consists of minority investors earnings in
consolidated  affiliates of $0.5 million and  amortization  of start-up costs of
$0.3 million in 1997, partially offset by earnings in unconsolidated affiliates.

                                       38
<PAGE>

Provision for Income Taxes

     Our provision for income taxes in 1998 and 1997 was $19.3 million and $11.1
million,  respectively.  On a pro forma basis,  giving  effect to the  Preferred
Payment  Systems  merger,  our provision for income taxes in 1998 and 1997 would
have been  $19.3  million  and $13.9  million,  respectively.  This  would  have
resulted  in pro forma  effective  tax rates of 46.2% and  65.9%,  respectively.
Excluding the tax effects of our  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. We expect
to provide for our 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

     Our total  revenues  increased  31.3% in 1997 to $489.3 million from $372.7
million in 1996.  Health  Services'  revenues  increased 22.1% in 1997 to $207.7
million from $170.0 million in 1996.  Managed Care Services'  revenues increased
39.0% in 1997 to $281.6 million from $202.6 million in 1996, as specialized cost
containment  revenues  increased  70.6% in 1997 to  $142.9  million  from  $83.8
million in 1996 and field case  management  revenues  increased 16.7% in 1997 to
$138.7 million from $118.9 million in 1996.

     Health Services' revenue growth resulted from:

     o   the acquisition of 16 occupational healthcare centers;

     o   the management of an additional four  occupational  healthcare  centers
         from Vencor, Inc. in the fourth quarter of 1997;

     o   an increase in business in our existing markets;

     o   development of sites in new markets; and

     o   an increase in consulting and other ancillary services.

     Managed Care  Services'  specialized  cost  containment  revenue  growth is
largely attributable to:

     o   the  acquisitions  of Focus,  Prompt,  First  Notice  Systems and About
         Health; and

     o   the  growth in  retrospective  medical  bill  review,  telephonic  case
         management and claims review services in existing service locations and
         the expansion into additional service locations.

     Managed Care Services'  field case  management  revenue growth is primarily
due to growth in revenues from existing service locations, and our opening of 13
offices during 1996 and 1997.

     Our total  contractual  allowances offset against revenues during the years
ended  December  31,  1997  and  1996  were  $14.7  million  and  $3.7  million,
respectively.

Cost of Services

     Our total cost of services  increased  28.5% in 1997 to $372.6 million from
$289.9 million in 1996.  Health  Services' cost of services  increased  18.8% in
1997 to $155.4 million from $130.8 million in 1996, while Managed Care Services'
cost of services  increased  36.5% in 1997 to $217.3 million from $159.2 million
in 1996.

     Our total gross profit margins increased to 23.8% in 1997 compared to 22.2%
in 1996.  Health  Services'  gross  profit  margins  increased  to 25.2% 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.

                                       39
<PAGE>


     Health  Services'  gross  profit  margin   improvement  has  resulted  from
increased  efficiencies  and  productivity.   Managed  Care  Services  has  seen
improvement  in gross  profit  margin  primarily  resulting  from a shift in its
revenue mix towards  specialized  cost  containment  services,  including  those
services provided by Focus, Prompt, First Notice Systems and About Health, which
historically  have had higher gross profit  margins than  revenues  derived from
field case management.

General and Administrative Expenses

     Our general and  administrative  expenses  increased 20.1% in 1997 to $39.8
million from $33.2  million in 1996, or 8.1% and 8.9% as a percentage of revenue
for 1997 and 1996  respectively.  This increase in general and adminis-  trative
expenses was principally  attributable to expenses  associated with acquisitions
and our continued investment in the Information Services and Technology Group.

Amortization of Intangibles

     Our  amortization  of intangibles  increased  71.6% in 1997 to $5.9 million
from $3.4 million 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:

     o   Focus;

     o   Prompt;

     o   First Notice Systems;

     o   About Health by Preferred Payment Systems;

     o   some occupational healthcare centers from Vencor, Inc.; and

     o   other smaller acquisitions.


Non-recurring Charge

     We recorded a  non-recurring  charge of $38.6 million  associated  with the
1997 merger of CRA and OccuSystems. The charges we incurred were approximately:

     o   $11.6 million for professional fees and services;

     o   $16.2 million in costs  associated  with  personnel  reductions and the
         consolidation of CRA's and OccuSystem's employee benefits;

     o   $5.9 million in facility consolidations and closings;

     o   $2.5 million for the write-off of start-up costs; and

     o   $2.4 million of other charges.

     At December  31,  1997,  approximately  $7.5  million of the  non-recurring
charge  remains  primarily  related to  personnel-related  charges and  facility
consolidations and closings.

Interest Expense

     Our interest  expense  increased $8.9 million in 1997 to $12.7 million from
$3.7 million in 1996 due  primarily to the issuance of $97.8  million  principal
amount of our 6% convertible  subordinated  notes in December 1996, the

                                       40
<PAGE>

issuance of  indebtedness  by  Preferred  Payment  Systems in August 1996 and to
increased  outstanding  credit  facility  borrowings  used  to  finance  certain
acquisitions.

Interest Income

     Our  interest  income  increased  $1.4 million in 1997 to $2.3 million from
$0.9 million in 1996 due primarily to the  investment  of excess cash  generated
from the issuance of our 6% convertible  subordinated notes until the funds were
utilized to finance certain acquisitions.

Other Expense, Net

     Our other expense, net is primarily made up of minority investors' earnings
in consolidated  affiliates.  These amounts remained consistent between 1996 and
1997 at $0.9 million.

Provision for Income Taxes

     Our provision for income taxes in 1997 and 1996 was $11.1 million and $13.4
million,  respectively.  On a pro forma basis,  giving  effect to the  Preferred
Payment  Systems  merger,  our provision for income taxes in 1997 and 1996 would
have been $13.9 million and $16.2 million, respectively,  resulting in pro forma
effective tax rates of 65.9% and 39.0%, respectively.  Excluding the tax effects
of the  non-recurring  charge,  our pro forma effective tax rate would have been
39.3% for 1997.

Seasonality

     Our business is seasonal in nature.  Patient visits at our Health Services'
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,  since employers generally hire
fewer  employees in the fourth  quarter,  the number of  pre-placement  physical
examinations  and drug and alcohol tests conducted at the medical centers during
that quarter is further  reduced.  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 our revenue growth
may obscure the effect of  seasonality in our financial  results,  the first and
fourth quarters generally reflect lower revenues when compared to our 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. We have completed a
number of acquisitions in recent years,  and the information  systems of some of
the acquired  operations  have not been fully  integrated  with our  information
systems.

     We have  formed  a Year  2000  Program  Office  to  provide  a  centralized
management function for our entire organization that will assist in identifying,
addressing and monitoring our Year 2000 readiness and compliance  programs.  Our
Year 2000 Program  Office has organized  teams at each division to research Year
2000 compliance  status and implement the appropriate  solutions.  Our Year 2000
Program includes five phases -- awareness, assessment,  remediation, testing and
implementation.  The  awareness  and  assessment  phases  are  complete  and the
remediation, testing and implementation phases are substantially complete.

     Our 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. Our Year 2000 Program Office also engaged an outside consultant
in the first quarter of 1999 to assist in inventory,  assessment and remediation
efforts of our information  systems  infrastructure  Year 2000  compliance.  The
remediation of our information systems infrastructure was substantially complete
by the third  quarter of 1999.  We  completed  in the fourth  quarter of 1998 an
internal inventory and assessment of non-information  technology  systems,  e.g.
embedded systems con-

                                       41
<PAGE>

tained in medical  equipment.  The  remediation  or  replacement  efforts of our
information systems  infrastructure and  non-information  technology systems was
substantially complete by the end of the third quarter of 1999.

     Our Year 2000 Program Office has  established a vendor  management  program
protocol for soliciting Year 2000 compliance  information from third parties and
requests  for  compliance  information  from  all  key  suppliers  and  selected
customers were sent in the fourth quarter of 1998 and the first quarter of 1999.
We gathered Year 2000 compliance information from third parties and received the
majority of third party  responses by the end of the third  quarter of 1999.  To
the extent responses have not been received, the division Year 2000 sponsors and
coordinators  have  ranked  the third  parties by level of  importance  to their
operations. Our Year 2000 Program Office conducted phone

surveys,  sent additional  mailings and performed research of public information
issued by the  third-party,  i.e., "web research." These responses have provided
compliancy  status  information that enables us to determine the extent to which
the Company may be vulnerable to those third parties' failure to remediate their
own Year 2000 issues.  The vendor  management  program  provides,  on an ongoing
basis, the compliancy response information to the divisions for their evaluation
and determination if any action is required.  The vendor management  program was
substantially completed by October 31, 1999.

     Our identified Year 2000 projects  overlap with our ongoing  investments in
information  technology,  as such, there are presently Year 2000 projects at the
remediation,  testing  and  implementation  phases.  We  believe  that  we  have
identified  most  "mission  critical"  issues and have executed or are executing
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.  We have  prepared  our  plans to have all
"mission critical" projects Year 2000 compliant by the end of the fourth quarter
of 1999. The majority of the "mission  critical"  projects have been remediated,
tested and deployed as of October 31, 1999. While some non-critical  systems may
not be addressed  until after  December  1999, we believe those systems will not
disrupt our  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.  We will continue to
formulate,  evaluate and refine contingency plans deemed necessary in the fourth
quarter of 1999.

     We currently  estimate  that the total cost of  implementing  our Year 2000
Program will be between $5.0 million and $10.0  million.  This estimate is based
upon presently available  information and will be updated as we continue through
implementation.  It is expected these costs will not be significantly  different
from our current planned investment for information  technology,  and therefore,
should  not  have  a  material  adverse  effect  on  our  long-term  results  of
operations,  liquidity or consolidated  financial position.  We made capital and
noncapital  investments  in the  Information  Services and  Technology  Group of
approximately  $32.0  million  in 1998  and  expect  our  investment  in 1999 to
approximate  $40.0  million.  Of this  investment,  our Year 2000 Program Office
incurred  expenses of  approximately  $1.9 million  through  September  30, 1999
primarily associated with the engagement of outside consultants to assist in the
inventory, assessment and remediation of Year 2000 affected areas.

     Although we do not anticipate any disruption in our operations or financial
reporting  as a result of system  upgrades  or  system  integrations,  we cannot
assure you that such disruption will not occur or that the desired benefits from
the Year 2000 compliance of our information and non-information  systems will be
realized.  If we do not identify and remediate Year 2000 issues prior to January
1, 2000, our operations  could be disrupted which could have a material  adverse
effect on our business or operating results or financial condition. In addition,
we place a high degree of reliance on computer systems of third parties, such as
customers,  trade  suppliers  and  computer  hardware  and  commercial  software
suppliers. Although we are 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 us. In addition,  our  operations  could be disrupted if the  companies  with
which we do business do not  identify  and correct any Year 2000 issues and such
failure adversely affects their ability to do business with us. If all Year 2000
issues are not identified and all action plans are not completed and contingency
plans become  necessary,  we may not be Year 2000  compliant  which could have a
material adverse effect on our 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 $34.9 million,  ($0.5
million) and $15.6 million for the years ended December 31, 1998, 1997 and 1996,
respectively,  and $4.3  million and $30.0  million for the first nine months of
1999 and 1998, respectively.  During 1998, working capital used $20.3 million of
cash  primarily  due to an  increase in accounts  receivable  of $19.8  million,
offset by a decrease in prepaid expenses and income taxes of $1.5 million and an
increase in accounts payable, accrued expenses and income taxes of $0.9 million.
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.  During the first nine months of
1999, working capital used $13.0 million of cash due primarily to an increase in
accounts  receivable  of $23.7  million  and prepaid  expenses  of $1.0  million
partially  offset by an  increase in  accounts  payable and accrued  expenses of
$11.7  million.   Within  the  next  twelve  months,   it  is  anticipated  that
approximately  $11.3  million  in cash  payments  will be  made  related  to the
non-recurring charges that occurred in the first quarter of 1998, fourth quarter
of 1998 and the third quarter of 1999.  These  expenditures  are  anticipated to
consist of $5.6 million of fees and other expenses  related to the merger,  $0.4
million of severance related costs, $3.9 million of facility related costs, $1.4
million of costs associated with settling claims on certain expired contracts.

     We used net cash of $18.1 million in connection  with  acquisitions,  $15.5
million to purchase marketable  securities and $34.2 million of cash to purchase
property  and  equipment  during  1998,  the  majority of which was spent on new
computer hardware and software technology. During the first nine months of 1999,
we used net cash of $43.3  million in  connection  with  acquisitions  and $26.0
million to purchase  property and equipment,  the majority of which was spent on
new computer and software technology  partially offset by $15.5 million provided
by the sale of marketable securities.

     Cash flows  provided by financing  activities of $121.6 million in 1998 was
due  primarily to the issuance of $230.0  million  principal  amount of our 4.5%
convertible  subordinated notes, $223.6 million, net of deferred finance fees. A
portion of the proceeds from the issuance of our 4.5%  convertible  subordinated
notes was used to:

     o   repay borrowings under our existing credit facility;

     o   repay debt assumed in our merger with Preferred Payment Systems; and

     o   for  the  payment  of  $15.0  million  to  Preferred   Payment  Systems
         dissenting shareholders.

     Net  proceeds  from the  issuance  of common  stock  under  employee  stock
purchase  and option plans and the related tax benefit was $14.4  million.  Cash
flows used by  financing  activities  of $41.1  million in the nine months ended
September 30, 1999 was due primarily to the payment of fees and expenses related
to the merger and deferred finance fees related to the merger financing.

     Our capital and  non-capital  investment  in the  Information  Services and
Technology  Group was  approximately  $32.0  million in 1998 and  expected to be
approximately  $40.0  million  in 1999.  We incur  capital  expenditures  in the
ordinary  course of  business  for the  purposes  of  information  services  and
technology,  improvements to leased facilities and equipment purchases necessary
to support our growth. We currently  anticipate that total capital  expenditures
over the next 12 months will be consistent  with the past two years.  We also do
not anticipate any unusual  material  expenditure  not already  disclosed in the
Year 2000 concern disclosure.


     We were in compliance with our covenants,  including our financial covenant
ratio tests, in the fourth quarter of 1999. We had borrowings  outstanding under
the revolving  credit  facility of $4.0 million as of December 31, 1999. We have
contacted  the  agent  under our  senior  credit  facilities  in order to review
whether an amendment to our financial  compliance ratios is necessary for future
periods.  Although we believe that we will succeed in these  efforts,  we cannot
assure  you that the banks  will agree to any  amendment  of the  senior  credit
facilities in the event that we find such an amendment is  necessary.  A failure
to comply with these  ratios  could  cause an event of default  under the senior
credit  facilities  which  could  result  in  an  acceleration  of  the  related
indebtedness before the terms of that indebtedness  otherwise requires us to pay
that indebtedness.


                                       43
<PAGE>


Such an  acceleration  would  also  constitute  an event of  default  under  the
indenture  relating  to the notes could also  result in an  acceleration  of the
notes before the indenture otherwise requires us to pay the notes.


     We believe that our cash balances,  the cash flow generated from operations
and  our  borrowing  capacity  under  our  revolving  credit  facility  will  be
sufficient  to  fund  our  working  capital,   occupational   healthcare  center
acquisitions and capital  expenditure  requirements for at least the next twelve
months.  Our  long-term  liquidity  needs will


consist of working capital and capital expenditure requirements,  the funding of
any future acquisitions,  and repayment of borrowings under our revolving credit
facility and the repayment of outstanding indebtedness.  We intend to fund these
long-term  liquidity  needs from the cash generated from  operations,  available
borrowings under our revolving credit facility and, if necessary, future debt or
equity  financing.  However,  we cannot be sure that any  future  debt or equity
financing will be available on terms favorable to us.

Legal Proceedings

     As of November 1, 1999, we were aware of one consolidated  lawsuit that was
originally filed in three suits by alleged stockholders of Concentra relating to
our merger with Yankee.  All three lawsuits were filed in the Chancery Court for
New Castle County,  Delaware.  Each lawsuit named  Concentra,  its directors and
Yankee as  defendants.  The  plaintiffs  in each  lawsuit  sought to represent a
putative class of all public holders of Concentra common stock.

     The  lawsuits  alleged,  among other  things,  that  Concentra's  directors
breached their fiduciary  duties to their  stockholders by approving our merger.
Specifically, the directors were alleged to have breached their fiduciary duties
of care and loyalty by failing to conduct an impartial  auction to determine the
maximum  value  attainable  for the common stock of  Concentra.  The  complaints
alleged that certain  relationships  between Welsh Carson and  Concentra  caused
Concentra's directors to favor Welsh Carson throughout the sale of Concentra and
to enter into a merger  agreement  that had the  effect of capping  the price of
Concentra's  stock.  The lawsuits  sought among other  things,  preliminary  and
permanent injunctive relief prohibiting consummation of the merger,  unspecified
damages, attorneys' fees and other relief.

     We have reached an agreement in principle to settle all  outstanding  class
action  litigation  filed in connection with the merger.  In connection with the
proposed  settlement,  we amended the proxy statement mailed to our stockholders
to disclose the relationship prior to the merger between Concentra, Welsh Carson
and the individuals  affiliated with Welsh Carson.  In return,  we, Welsh Carson
and their respective affiliates,  officers,  directors and other representatives
will  be  released  from  all  claims  of the  class.  As of the  date  of  this
prospectus, the settlement remains conditioned upon the approval of the Delaware
court. Under the terms of the proposed settlement,  the defendants agreed to pay
up to $325,000 in court-awarded attorneys' fees and expenses.

                                       44

                                    BUSINESS

     We are the largest company dedicated  primarily to serving the occupational
healthcare  market.  We  provide  initial  treatment  for  approximately  4%  of
workplace  injuries  in the United  States and perform  non-injury  occupational
healthcare services for over 80,000 local employers. We provide specialized cost
containment  and field case management  services to over 2,000 customers  across
the United  States  and  Canada,  including  most of the major  underwriters  of
worker's  compensation  insurance,  third-party  administrators and self-insured
employers.  We are also the  largest  provider  of  out-of-network  bill  review
services  to  the  group   health   marketplace.   We  offer  a   continuum   of
healthcare-related    services   to   employers,    insurers   and   third-party
administrators  of  all  sizes  and  are  compensated  for  our  services  on  a
non-risk-bearing, fee-for-service or percentage-of-savings basis. Less than 0.5%
of our revenues are dependent on Medicare or Medicaid reimbursement.

     Our services reduce the customer's healthcare costs by:

     o   efficiently  managing the  application  of care and the  return-to-work
         process,  thereby providing appropriate medical care while reducing the
         non-medical costs associated with a claim; and

     o   using sophisticated cost containment techniques to determine the proper
         pricing of care once it has been administered.

     We  believe  that  by  offering  both  the  provision  of care  and  claims
management  services,  we are in a unique  position  to  provide  comprehensive,
integrated  services  on a bundled or  unbundled  basis to  national or regional
accounts and local  employers.  In addition to the  occupational  healthcare and
group health  markets,  we also provide  cost  containment  services to the auto
insurance market as well as social security  disability advocacy services to the
long-term  disability insurance market. In 1998, we generated revenues of $611.1
million.

     With healthcare costs rising,  we believe that payors will seek to increase
the use of cost saving  strategies,  such as those we offer,  to minimize  these
costs. Our comprehensive services are comprised of three distinct categories:

     o   healthcare services;

     o   specialized cost containment services; and

     o   field case management services.

     We provide healthcare services through our network of 201 owned and managed
occupational  healthcare  centers,  located  in 60  markets  in 32  states as of
November 1, 1999. As a primary  starting  point for the provision of care in the
workers'  compensation market, our occupational  healthcare centers are designed
to  efficiently  provide  quality care to patients while also providing an entry
point for our other  cost  containment  services.  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.  In 1998,  revenues from healthcare  services  represented
approximately 42% of our total revenues.

     Specialized  cost  containment  services consist of first report of injury,
telephonic case management,  utilization management, both in- and out-of-network
bill review, preferred provider organization network access, independent medical
exams and peer reviews. These specialized cost containment services are designed
to monitor the timing and appropriateness of medical care, as well as the proper
pricing for that care.  These  services are  primarily  provided to the workers'
compensation  market,  except for out-of-network bill review which we provide to
the group health  market.  We are currently  expanding our  out-of-network  bill
review  services to the workers'  compensation  and auto insurance  markets.  In
1998,   revenues  from  specialized  cost   containment   services   represented
approximately 30% of our total revenues.

     We provide field case management services to a national customer base using
approximately  1,000  full-time  field  case  managers.  Field  case  management
services involve working on a one-on-one basis with injured employees



                                       45
<PAGE>

and aiding 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. In 1998,  revenues from field case management  services
represented approximately 28% of our total revenues.

Industry Overview

Occupational Healthcare

     Occupational healthcare is largely provided by independent physicians,  who
have experienced  increasing  pressures in recent years from growing  regulatory
complexity  and other factors,  as well as hospital  emergency  departments  and
other urgent care providers.  We anticipate that competition in the occupational
healthcare  market may shift to specialized  provider groups,  such as groups we
manage. Occupational healthcare services consist of two primary components:

     o   workers' compensation injury care and related services; and

     o   non-injury  occupational  healthcare services related to employer needs
         or statutory requirements.

     Workers' Compensation Injury Care

     Workers' compensation is a state-mandated,  comprehensive insurance program
that requires employers to fund all medical expenses, lost wages and other costs
resulting from  work-related  injuries and illnesses with no co-payment from the
employee.  Since their introduction in the early 1900s, these programs have been
adopted by 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 related 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. 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 the Workers'  Compensation  Monitor data published in the 1998
Workers'  Compensation Year Book, total workers' compensation costs to employers
in the United States were estimated to be  approximately  $92.7 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,  we
believe that we are the only  integrated  provider of healthcare  management and
cost  containment  services  offering a full range of services  on a  nationwide
basis.

     The  dollar   amount  of  workers'   compensation   claims  has   increased
significantly in recent years,  resulting in escalating  costs to employers.  We
believe that workers' compensation costs will continue to rise primarily because
of:

     o   broader  definitions of work-related  injuries and illnesses covered by
         workers' compensation laws;

     o   the  shifting of medical  costs from group health plans to the workers'
         compensation system;

     o   an aging work force;

                                       46
<PAGE>


     o   the continued  requirement that employers pay all of an employee's cost
         of medical treatment, without any co-payment or deductible, and related
         lost wages and non-medical costs; and

     o   the under-use to date of comprehensive cost containment programs in the
         workers compensation industry.

     As workers'  compensation  costs  increase,  we expect that  employers will
continue to seek and use strategies and programs to reduce workers' compensation
costs and to improve  worker  productivity,  health and safety.  We believe that
clients' use of our 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.

     Provider  reimbursement methods vary on a state-by-state basis. As of March
1998, 40 states have adopted fee schedules under 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  fees charged in the particular  state in which
the services  are  provided.  These usual,  customary  and  reasonable  fees are
commonly called UCR. Of the 32 states in which we currently operate occupational
healthcare centers, as of November 1999, 24 have fee schedules.

     Limits on an  employee's  right to choose a  specific  healthcare  provider
depend on the particular state statute.  According to the Workers'  Compensation
Research  Institute,  as of March 1998, 25 states limited the employee's initial
choice of provider,  two states  prohibited  employee  change of provider and 37
states  and the  District  of  Columbia  placed  restrictions  on all  employees
switching  providers,  including  provisions requiring employer approval for any
changes.  Generally,  the  employer  will also have the  ability  to direct  the
employee when the employer is self-insured.  It has been our experience that our
results of  operations  and  prospects in a particular  state do not  materially
depend on state statutes regarding direction of care.  Consequently,  we believe
that employers greatly influence their employees'  choices of physicians even in
states in which the employees may select their providers.

     Non-Injury Healthcare Services

     Non-injury occupational healthcare services include:

     o   employment-related physical examinations;

     o   drug and alcohol testing;

     o   functional capacity testing; and

     o   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-mandated  physical  examinations.  Federal laws governing  health
issues in the  workplace,  including the Americans with  Disabilities  Act, have
increased employers' demand for healthcare  professionals who are experts in the
delivery of these regulated services.

Cost Containment Services

     Cost containment  techniques are intended to control the cost of healthcare
services  and to measure the  performance  of providers  of  healthcare  through
intervention  and on-going  review of proposed  services  and services  actually
provided.  Healthcare and insurance companies  originally developed managed care
techniques to stem the rising costs of group healthcare. Historically, employers
were slow to apply  managed  care  techniques  to  workers'  compensation  costs
primarily  because  the  total  costs are  relatively  small  compared  to those
associated with group health

                                       47
<PAGE>

benefits and because state-by-state regulations related to workers' compensation
are 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  in an effort to allow  employers  to
control  their  workers'  compensation  costs.  Managed care  organization  laws
generally  provide  employers an opportunity to channel  injured  employees into
provider  networks.  In certain states,  managed care  organization laws require
licensed managed care organizations to offer certain specified services, such as
utilization management,  case management,  peer review and provider bill review.
Most of the managed care organization laws adopted to date establish a framework
within  which a company  such as ours 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   cost  containment   services  include  two  broad
categories:

     o   specialized cost containment services; and

     o   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:

     o   first report of injury;

     o   telephonic case management;

     o   utilization management;

     o   precertification and concurrent review;

     o   both in- and out-of-network bill review services;

     o   preferred provider organization network access;

     o   independent medical examinations; and

     o   peer reviews.

     Field case management services involve:

     o   working on a one-on-one basis with injured employees; and

     o   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

     According to the Health  Insurance  Association of America,  private health
insurance claims payments were estimated to be  approximately  $281.7 billion in
1995.  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 a  greater  incidence  of
over-use, 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.

Our Services and Operations

     The workers'  compensation and group health markets represent a significant
opportunity  for the full range of healthcare  management  and cost  containment
services we provide. In each of these markets, insurance companies, self-insured
employers  and third party  administrators  have a need for our services as they
always try to control their rising healthcare costs.

Healthcare Services

     Occupational Healthcare Centers

     Our 201  occupational  healthcare  centers  at  November  1,  1999  provide
treatment for:

     o   work-related injuries and illnesses;

     o   physical therapy;

     o   preplacement physical examinations and evaluations;

     o   certain diagnostic testing;

     o   drug and alcohol testing; and

     o   various other  employer-requested or  government-mandated  occupational
         health services.

     During 1998,  approximately  52% of all patient  visits to our 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.

     Each of our centers is staffed with at least one licensed  physician who is
an employee of a physician group and at least one licensed  physical  therapist.
The licensed  physicians are generally  experienced in occupational  medicine or
have  emergency,   family  practice,   internal  medicine  or  general  medicine
backgrounds. Most centers use 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 our  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 us and our physician  groups with respect to
the 346  affiliated  physicians  as of  November  1,  1999 have  40-year  terms.
Pursuant  to each  management  agreement,  we provide a wide  array of  business
services to the physician groups, such as:

     o   providing nurses and other medical support personnel;

                                      49
<PAGE>

     o   practice and facilities management;

     o   billing and collection;

     o   accounting;

     o   tax and financial management;

     o   human resource management;

     o   risk management;

     o   marketing and information-based services such as process management and
         outcome analysis.

     As another service to the physician groups, we recruit physicians,  nurses,
physical  therapists and other healthcare  providers.  We collect receivables on
behalf of the physician  groups and advance funds for payment of each  physician
group's  expenses,  including  salaries,  shortly after services are rendered to
patients.  We receive 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.  We provide  services to the
physician  groups as an independent  contractor and are responsible only for the
non-medical  aspects of the physician  groups'  practices.  The physician groups
retain sole  responsibility for all medical  decisions,  including the hiring of
medical personnel.

     The physician groups operate in accordance with annual budgets  established
in consultation with us. The management  agreements between the physician groups
and our company  provide that in no event shall we have any obligation to supply
out of our funds working capital for the physician  groups or their  operations.
Accordingly, we retain sole discretion over the decision to advance funds to the
physician  groups and regarding the amount of any such advances.  Because we own
and  operate  the  occupational  healthcare  centers,  we also  retain  ultimate
authority to determine the type of equipment used in the centers,  the number of
medical  personnel for each center and other fiscal  matters with respect to the
operation of the centers.

     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 physicians group 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.  Under each  management  agreement,  the
physician  group  indemnifies  us from any loss or expense  arising from acts or
omissions  of the  physician  group or our  professionals  or  other  personnel,
including claims for malpractice.

     Joint Ventures and Management Agreements

     Our strategy is to continue to develop clusters of occupational  healthcare
centers in new and  existing  geographic  markets  through the  acquisition  and
development of occupational  healthcare  centers. In selected markets in which a
hospital management company,  hospital system or other healthcare provider has a
significant  presence,  we may focus our  expansion  efforts on strategic  joint
ventures  or  management  contracts.  In our  joint  venture  relationships,  we
typically  acquire a majority  ownership  interest  in the  venture and agree to
manage the venture for a  management  fee based on net  revenues.  We  currently
manage 11 joint ventures  through which we operate 29 centers.  In addition,  we
have  entered  into three  management  agreements  through  which we operate six
centers.

     Other Ancillary Programs

     We offer other  ancillary  programs  as  described  below.  It has been our
experience  that,  by offering a full range of programs to  complement  our core
healthcare management services, it strengthens our relationships with existing

                                       50
<PAGE>

clients and increases the  likelihood of attracting  new clients.  We anticipate
expanding our ancillary programs as needed to address  occupational  legislation
and regulations enacted in the future.

     Compliance  With the Americans  with  Disabilities  Act. The Americans with
Disabilities  Act 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
Americans  with  Disabilities  Act now applies to all employers  with 15 or more
employees.  Through our "ADApt  Program," we assist employers with the Americans
with  Disabilities  Act  compliance  issues by  addressing  the  Americans  with
Disabilities  Act  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 Americans with Disabilities Act guidelines.

     Risk  Assessment  and  Injury  Prevention  Programs.  We assist  clients in
reducing  workplace  injuries and illnesses  through our on-site risk assessment
and injury prevention programs. These programs include:

     o   identifying workplace hazards;

     o   designing plant-specific safety programs; and

     o   helping  clients  comply  with  federal and state  occupational  health
         regulations.

     We also provide ongoing educational programs for our clients.

     For 1998, revenues from healthcare services  represented  approximately 42%
of our total revenues.

Specialized Cost Containment Services

     We provide 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:

     o   first report of injury;

     o   telephonic case management;

     o   utilization management;

     o   precertification and concurrent review;

     o   in and out-of-network bill review services;

     o   preferred provider organization network access;

     o   independent medical examinations;

     o   and peer reviews.

     We are able to offer our  services  separately  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  aggressively
manage  the costs  associated  with a  work-related  injury.  Our  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,  we also  provide  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.

                                       51
<PAGE>

     We believe that the demand for specialized cost  containment  services will
continue to increase due to a number of factors, including:

     o   the increasing  payor awareness of the availability of these techniques
         for cost containment and case management;

     o   the  effectiveness  of managed care  techniques  at reducing  costs for
         group health insurance plans;

     o   the  verifiable   nature  of  the  savings  that  can  be  obtained  by
         application of specialized  cost containment  techniques  applicable to
         workers' compensation; and

     o   the broad  applicability of these techniques to all injured  employees,
         not just severely injured employees likely to be absent from work.

     Out-of-Network Bill Review

     Through  Concentra  Preferred  Systems,  we  continue  to expand our market
presence in bill review services. We believe that Concentra Preferred Systems is
the market  leader in this line of  business in the group  health  market 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.  Concentra Preferred Systems uses a variety of techniques to reduce
expenses by repricing  hospital and other facilities' bills. Using its services,
Concentra  Preferred  Systems 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:

     o   professional fee negotiation;

     o   line-item analysis;

     o   other specialized audit and bill review processes; and

     o   access to a nationwide preferred provider organization network.

     Concentra Preferred Systems provides out-of-network bill review services to
healthcare payors in most risk categories:

     o   indemnity;

     o   preferred provider organization;

     o   health maintenance organization;

     o   ERISA self-insured plans;

     o   Taft-Hartley Plans;

     o   reinsurance carriers; and

     o   intermediaries such as administrative  services organizations and third
         party administrators.

     Concentra  Preferred  Systems 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:

     o   over-use;


                                       52
<PAGE>

     o   upcoding;

     o   cost shifting;

     o   various forms of revenue enhancement tactics; and

     o   inflated retail charge practices.

     The current technology  employed at Concentra Preferred Systems is designed
to:

     o   review most provider bill types;

     o   employ four transmission methods to aid the exchange of bill data;

     o   use  various  database  technologies  as  part  of the  bill  screening
         process;

     o   score each bill referred based on the individual  service  requirements
         of each client group; and

     o   route each bill to the most appropriate bill review service included in
         our range of cost containment services.

     Concentra Preferred Systems has packaged this process and markets it as the
Healthcare  Bill  Management  System.  The system  affords  large payor  clients
breadth of service  and  capacity,  consolidated  and  uniform  cost  management
capability, rigorous due diligence and high quality performance.

     First Report of Injury

     Through First Notice  Systems,  we provide a  computerized  first report of
injury/loss  reporting  service using two  centralized  national call centers to
which an individual,  employer or insurance company claims adjuster communicates
reports  of  injuries  or losses as soon as they  occur.  First  Notice  Systems
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,  provides  us and our  customers  with an early
intervention tool to maximize control over workers' compensation and auto claims
and also provides us with cross-selling and referral opportunities.

     Telephonic Case Management

     This service  provides for  short-duration  of 30 to 90 days for telephonic
management of workers'  compensation  claims.  The  telephonic  case  management
units:

     o   accept first reports of injury;

     o   negotiate discounts with hospitals and other providers;

     o   identify care alternatives; and

     o   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 our field case management offices.



                                       53

     Utilization Management: Precertification and Concurrent Review

     Our  precertification and concurrent review services are used by clients to
ensure that certain medical procedures are precertified by one of our registered
nurses and/or physicians for medical necessity and  appropriateness of treatment
before the medical  procedure is performed.  Our  determinations  represent only
recommendations to the customer,  the ultimate decision to approve or disapprove
request  is made by the  claims  adjuster.  Precertification  calls  are made by
either  the  claimant  or  the  provider  to one  of  our  national  utilization
management reporting units. After a treatment plan has been precertified, one of
our employees  performs a follow-up call,  concurrent  review,  at the end of an
approved time period to evaluate compliance and/or discuss alternative plans.

     Bill Review

     Through  a  sophisticated  software  program,  we  review  and  reduce  our
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  bill  review  service  enables  clients to access  certain  preferred
provider  organization pricing schedules that represent additional savings below
the fee  schedules or UCR rates.  The savings to our clients as a result of this
service can be  significant.  Bill review also creates an  important  historical
database for provider  practice  patterns and managed care  provider  compliance
requirements.

     Access to Preferred Provider Networks

     Through Focus,  we provide our clients with access to a national  preferred
provider organization network. This network provides injured workers with access
to quality medical care at pre-negotiated volume discounts, thereby offering our
clients  the  ability  to  influence,  or in  certain  states to  direct,  their
employees  into  the  preferred  provider  organization  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 preferred  provider  organization  arrangements  generate
additional  savings  through the  retrospective  bill review  program  described
above.  Focus's  national  network  includes  approximately  227,000  individual
providers  and over  2,800  hospitals  covering  42 states and the  District  of
Columbia.

     Independent Medical Exams

     Independent  medical  examinations  are  provided  to assess the extent and
nature of an employee's injury or illness. We provide our clients with access to
independent  physicians who perform the independent medical examinations from 14
of our 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.

     For 1998, revenues from specialized cost containment  services  represented
approximately 30% of our total revenues.

Field Case Management Services

     We provide  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.  Our 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.

                                       54
<PAGE>

     Our field case management  services  consist of one-on-one  management of a
work-related  injury by approximately  1,000 full-time 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 our marketer.  Our 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 our 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.

     We believe that the following  factors will contribute to continued  growth
of our field case management services:

     o   increased acceptance of field case management techniques due to greater
         exposure to the workers' compensation managed care market;

     o   earlier  identification of individuals in need of field case management
         services  due  to  increased   utilization  of  our  specialized   cost
         containment services, particularly early intervention services;

     o   increased  market  share at the  expense of  smaller,  undercapitalized
         competitors; and

     o   the  ability to access  national  accounts  for use of case  management
         services.

     For  1998,  revenues  from  field  case  management  services   represented
approximately 28% of our total revenues.

Customers

     Our  occupational  healthcare  centers  currently  serve  more than  80,000
employers-including  local  offices  of  national  companies-ranging  from large
corporations to businesses  with only a few employees.  We serve more than 2,000
specialized  cost  containment  and field case management  customers  across the
United States and Canada,  including most of the major  underwriters of workers'
compensation insurance, third party administrators and self-insured employers.

     We are compensated primarily on a fee-for-service or  percentage-of-savings
basis.  Our largest  customer  represented  less than 6% of our total revenue in
1998. We have not entered into written  agreements  with most of our  healthcare
services  customers.  Many of our  specialized  cost  containment and field case
management relationships are based on written agreements.  However, either we or
the customer can terminate most of these agreements on short notice.  We have no
risk-bearing  or  capitated  arrangements.  Less than 0.5% of our  revenues  are
dependent on Medicare or Medicaid reimbursement.

Sales and Marketing

     We  actively  market  our  services  primarily  to  workers'   compensation
insurance companies, third party administrators,  employers and employer groups.
We  also  market  to the  group  health,  automobile  insurance  and  disability
insurance markets. Our marketing  organization includes over 350 full-time sales
and marketing personnel, or their part-time equivalent.

     We market our  services at both the local  insurance  company  adjuster and
employer level. In addition, we market our 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.  We have a dedicated staff of
national  accounts  salespeople  responsible for marketing and  coordinating our
full range of services to corporate offices.

     Our  local  marketing  has been a  critically  important  component  of our
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,


                                       55
<PAGE>


     the  expansion  of  comprehensive  managed  care  legislation,   continuing
receptiveness to workers'  compensation change and a more comprehensive  product
offering  by us  demand  that we  continue  to focus on  marketing  to  national
headquarters offices of insurance companies and self-insured  companies. As part
of our  coordinated  marketing  effort,  we  periodically  distribute  follow-up
questionnaires to patients,  insurers and employers to monitor satisfaction with
our services.

Quality Assurance

     We  routinely  use  internal  audits to test the quality of our delivery of
services. We conduct 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.  We conduct 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, we conduct follow-up audits
to ensure that recommendations from the initial audit have been implemented.

Competition

Healthcare Services

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

     We believe that we compete effectively because of:

     o   our specialization in the occupational healthcare industry;

     o   or broad knowledge and expertise;

     o   the effectiveness of our services as measured by favorable outcome;

     o   our ability to offer services in multiple markets; and

     o   our information systems.

     We believe that we enjoy a  competitive  advantage by  specializing  in and
focusing on occupational healthcare at the primary care provider level, which as
the entry  point  into the  occupational  healthcare  system  is well  suited to
controlling the total costs of a claim. We do not believe that any other company
offers the full range of services we provide.

     The  recruiting  of  physicians,  physical  therapists,  nurses  and  other
healthcare providers can be competitive.  However, our recruiting becomes easier
as we grow and become more widely known by healthcare providers.

Specialized Cost Containment and Field Case Management Services

     The managed  care  services  market is  fragmented,  with a large number of
competitors. We compete with numerous companies, including national managed care
providers,  smaller independent providers,  and insurance companies. Our primary
competitors are companies that offer one or more workers'  compensation  managed
care services on a national basis.  We also compete with many smaller  companies
that generally provide  unbundled  services on a national basis. We also compete
with many 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

                                       56
<PAGE>


carrier's own personnel or by outsourcing various services to providers
such as us. We believe that this competitive  environment will continue into the
foreseeable future.

     We believe that we compete effectively because of:

     o   our  specialized  knowledge and expertise in the workers'  compensation
         managed care services industry;

     o   the effectiveness of our services;

     o   our ability to offer a full range of services in multiple markets;

     o   our information systems; and

     o   the prices at which we offer our services.


Information Systems and Technology

     We maintain a fundamental  commitment to the development and implementation
of advanced  information  technology,  with a  considerable  focus on  web-based
applications.  We  believe  that our  information  systems  enable us to improve
referrals among our full range of services,  streamline patient care and enhance
outcomes reporting. This makes our operations more efficient while improving our
ability to demonstrate the costs savings our services provide to our clients.

     We have substantially  completed the implementation of a wide area network,
or WAN,  in each  market  in  which we  provide  healthcare  services.  When the
implementation is complete, all occupational healthcare centers in a market will
use a  patient  administration  system,  named  "OccuSource,"  which  runs  on a
client/server  architecture  allowing  each  center to access and share a common
database  for our market.  The database  contains  employer  protocols,  patient
records and other information regarding our 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.
We are  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.  We  believe  that  our  commitment  to  continued
development  of  our  healthcare   information  system  provides  a  unique  and
sustainable competitive advantage within the occupational healthcare industry.

     We have  developed  and, in the future,  may license to third parties a new
internet-based first notice of loss reporting system for all lines of insurance,
named FNSNet.  The application  extends our 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 our First Notice
subsidiary to handle calls with greater speed and efficiency.

     Our  newly-developed  Integrated Case  Management  Software System aids and
speeds up the daily tasks of our 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 our offices,  as well as
among  employees in the same office.  The Integrated  Case  Management  Software
System is integrated  with the FNSNet  web-based  product.  The Integrated  Case
Management  Software System application  enables a clear,  precise and immediate
transmission  of data from First  Notice  into the  Integrated  Case  Management
Software  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  the
Integrated Case  Management  Software System allow for shared data in situations
in which  multiple  case  managers are working on a case.  The  Integrated  Case
Management  Software  System also creates better  customer access to information
and allows us to produce  specific,  user-friendly  reports to  demonstrate  the
value of our services.

     Finally, our subsidiary, Concentra Preferred Systems, uses our proprietary,
technology-based  Healthcare  Bill  Management  System  for  our  out-of-network
medical claims review  services.  Client bills are accessed and entered into the
Healthcare Bill  Management  System in a variety of ways,  including  electronic
bill   identification   within  the  client's  claim  adjudication  system  with
subsequent  EDI transfer to Concentra  Preferred  Systems,  entry of appropriate
bills into a  customized,  Data Access  Point  system,  on-site  bill entry by a
Concentra  Preferred  Systems  employee into the Data Access Point  system,  and
overnight  mail or facsimile of client  bills to a Concentra  Preferred  Systems
service center.  These access  strategies are designed to increase the number of
appropriate bills that Concentra  Preferred  Systems receives,  while minimizing
the administrative cost to the client. Once a bill is electronically or manually
entered  into the  Healthcare  Bill  Management  System,  the bill is  evaluated
against Concentra Preferred Systems 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
Concentra  Preferred  System's client preference  profile that is created at the
time of Concentra  Preferred  Systems initial  engagement  with the client.  The
Healthcare  Bill  Management  System 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
Concentra Preferred Systems service department.

Government Regulation

General

     As a provider of healthcare  management and cost containment  services,  we
are subject to extensive and increasing  regulation by a number of  governmental
entities at the federal, state and local levels. We are 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  our  operations  fall into  four  general
categories:

     o   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  services we
         provide;

     o   laws regarding the provision of healthcare services generally;

     o   laws regulating the operation of managed care provider networks; and

     o   other laws and regulations of general applicability.


Workers' Compensation Laws and Regulations

     In  performing   workers'   compensation   healthcare   services  and  cost
containment  services,  we 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, 24 of the states in which we do
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,  we adjust our
charges to the usual, customary and reasonable levels accepted by the payor.

     Many  states,  including a number of those in which we  transact  business,
have licensing,  and other regulatory requirements that apply to our specialized
cost containment and field case management business. Approximately half



                                       58
<PAGE>

of the states have  enacted  laws that  require  licensing  of  businesses  that
provide  medical  review  services,  such as ours.  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 us or to provider networks that we have organized
and may  organize  in the future.  To the extent  that we are  governed by these
regulations,  we 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 ours
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 ours. We attempt to structure all of
our  healthcare  services  operations to comply with  applicable  state statutes
regarding medical practice, fee-splitting and similar issues. However, there can
be no assurance:

     o   that courts or  governmental  officials  with the power to interpret or
         enforce  these  laws and  regulations  will not  assert  that we are in
         violation of such laws and regulations; or

     o   that  future  interpretations  of such  laws and  regulations  will not
         require us to modify the structure and organization of our business.

Fraud and Abuse 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,  as of January 1, 1995, certain  anti-referral
provisions,  the  Stark  Amendments,  prohibit  a  physician  with a  "financial
relationship"  with 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 us.

     At least  seven of the states  where we  conduct  our  healthcare  services
business-Arizona,  California,  Florida,  Illinois,  Maryland,  New Jersey,  and
Texas-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.  Even in states
which have not enacted such statutes, we believe that regulatory authorities and
state  courts  interpreting  these  statutes  may regard  federal  law under the
Anti-Kickback Statute and the Stark Amendments as persuasive.

     We believe  that our  arrangements  with the  physician  groups  should not
violate the  Anti-Kickback  Statute,  the Stark  Amendments and applicable state
laws.  However,   all  of  the  above  laws  are  subject  to  modification  and
interpretation and have not often been interpreted by appropriate authorities in
a manner  applicable  to our  business.  Moreover,  these laws are  enforced  by
authorities vested with broad discretion.  We have attempted to structure all of
our operations so that they should not violate any applicable  anti-kickback and
anti-referral  prohibitions.  We also continually  monitor  developments in this
area. If these laws are interpreted in a manner  contrary to our  interpretation
or are  reinterpreted or amended,  or if new legislation is enacted with respect
to healthcare fraud and abuse,  illegal  remuneration or similar issues, we will
seek to  restructure  any affected  operations to maintain our  compliance  with
applicable law. We cannot assure you that such  restructuring  will be possible,
or,  if  possible,  will  not  adversely  affect  our  business  or  results  of
operations.

Specialized Cost Containment Services

     Many of our 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 ours, 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 us, which may have an adverse  impact upon our ability to compete with other
available alternatives for healthcare cost control.

Use of Provider Networks

     Our  ability  to  provide  comprehensive  healthcare  management  and  cost
containment  services  depends in part on our ability to contract with or create
networks of healthcare  providers  which share our  objectives.  For some of our
clients,  we offer  injured  workers  access to  networks of  providers  who are
selected by us 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 us or to
provider  networks  that  we  may  develop  or  acquire.  To  the  extent  these
regulations apply to us, we may be subject to:

     o   additional licensing;

     o   requirements;

     o   financial oversight; and

     o   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,
or ERISA.  ERISA is a complex  set of laws and  regulations  subject to periodic
interpretation  by the Internal  Revenue  Service and the  Department  of Labor.
ERISA  regulates  certain aspects of the  relationship  between our managed care
contracts and employers that maintain  employee  benefit plans subject to ERISA.
The Department of Labor is engaged in ongoing ERISA enforcement  activities that
may result in additional constraints on how ERISA-governed benefit plans conduct
their  activities.  We  cannot  assure  you that  future  revisions  to ERISA or
judicial or regulatory interpretations of ERISA will not have a material adverse
effect on our business or results of operations.

Environmental

     We are subject to various federal, state and local laws and regulations for
the  protection  of human  health and  environment,  including  the  disposal of
infectious   medical  waste  and  other  waste  generated  at  our  occupational
healthcare  centers.  If an  environmental  regulatory  agency  finds any of our
centers to be in violation of  environmental  laws,  penalties  and fines may be
imposed for each day of violation,  and the affected facility could be forced to
cease operations.  While we believe that our environmental practices,  including
waste  handling  and  discharge  practices,  are  in  material  compliance  with
applicable  law,  future claims or changes in  environmental  laws could have an
adverse effect on our business.

Seasonality

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

                                       60
<PAGE>

     Plant closings, vacations and holidays during the first and fourth quarters
result in fewer patient visits at our 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 our centers during that quarter.  See  "Management's
Discussion    and   Analysis   of   Financial    Conditions   and   Results   of
Operations--Seasonality."

Insurance

     We and our physician groups maintain medical  malpractice  insurance in the
amount of $1.0 million per incident/$3.0  million annual aggregate per provider,
subject to an annual aggregate limit in the amount of $20.0 million. Pursuant to
the management  agreements  between us and the physician groups,  each physician
group  has  agreed  to  indemnify  us from  certain  losses,  including  medical
malpractice.  We maintain an errors and  omissions  liability  insurance  policy
covering  all aspects of our managed  care  services.  This policy has limits of
$1.0 million per claim/$3.0 million annual aggregate.

     In addition, we maintain $3.0 million 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 $30.0 million per  occurrence  and
$30.0 million in the aggregate.

Employees

     We had  approximately  8,800  employees  at November  1, 1999.  None of our
employees is subject to a collective bargaining  agreement.  We have experienced
no work  stoppages  and  believe  that our  employee  relations  are  good.  All
physicians,  physician assistants and physical therapists providing professional
services in our occupational  healthcare centers are either employed by or under
contract with the physician groups.

Properties

     Our  principal  corporate  office is located in Boston,  Massachusetts.  We
lease the 11,000 square feet of space in this site pursuant to a lease agreement
expiring in 2003. We make annual rental  payments  under that lease of $396,000.
Except for 12 properties  owned by us, we lease all of our offices located in 49
states,  the District of Columbia  and Canada.  Twelve of our offices are leased
from Colonial  Realty Trust,  of which Lois E.  Silverman,  a former director of
Concentra,  is a trustee and  beneficiary.  We believe that our  facilities  are
adequate  for our  current  needs and that  suitable  additional  space  will be
available as required.

The Board of Directors

Corporate Governance

     Pursuant  to the  Delaware  General  Corporation  Law,  as  implemented  by
Concentra's Certificate of Incorporation and Bylaws, the business,  property and
affairs of Concentra  are managed  under the  direction of a board of directors.
Members of this board are kept  informed  of the  Concentra'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.

     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 (1) the total number of meetings  held by the board and (2)
the total  number of meetings  held by all  committees  of the board on which he
served.

Committees of the Board of Directors

     During  1998,  the  board  of  directors  of  Concentra  had  two  standing
committees:  an Audit Committee, now known as the Audit and Compliance Committee
and an  Option  and  Compensation  Committee,  now  known  as  the  Compensation
Committee.

     The Audit Committee held two meetings in 1998. The Audit Committee  reviews
the  adequacy  of  Concentra's   system  of  internal  controls  and  accounting
practices.  In  addition,  the Audit  Committee  reviews the scope of the annual
audit of Concentra's independent public accountants,  Arthur Anderson LLP, prior
to its  commencement,  and  reviews the types of  services  for which  Concentra
retains Arthur Anderson LLP. Commencing in December 1998, the board of directors
designated the Audit Committee as the committee  charged with primary  oversight
of Concentra'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  Concentra,  review and approve the salary
administration  program for Concentra and administer  Concentra's  incentive and
stock option plans.

     During the fiscal year ended  December 31,  1998,  the members of the Audit
Committee were Willis D.  Gradison,  Jr.,  Mitchell T. Rabkin,  M.D. and Lois E.
Silverman.  Currently,  D. Scott  Mackesy,  Steven E. Nelson and John K. Carlyle
serve on the Audit and Compliance Committee.

     During the fiscal year ended  December  31,1998,  the members of the Option
and Compensation  Committee were John K. Carlyle,  George H. Conrades and Robert
A. Ortenzio.  Currently,  John K. Carlyle,  Carlos  Ferrer,  Paul B. Queally and
Andrew M. Paul serve on the Compensation Committee.


Compensation Committee Interlocks and Insider Participation

     Messrs.  Paul and Queally are managing  members of the sole general partner
of Welsh Carson. Because of these affiliations,  Messrs. Paul and Queally may be
deemed to have a material  interest  in the  matters  described  under  "Certain
Relationships and Related Transactions--Equity Investor Agreements."

Compensation of Directors

     Concentra  Operating.  None of the  directors of Concentra  Operating  will
receive any remuneration from Concentra  Operating for their attendance at board
and committee meetings during 1999.

     Concentra.  During  1998,  each  director  who was not also an  employee of
Concentra  automatically  received  options for 5,000 shares of Concentra common
stock and restricted  stock valued at $15,000 under  Concentra's  1997 Long-Term
Incentive  Plan to each  director  who was not an  employee  on the date of each
annual  meeting  of  Concentra  stockholders.   During  such  period,  Concentra
directors  who were also  employees of Concentra  received no  remuneration  for
attendance at board and committee meetings.

     Concentra  directors who are not employees receive  compensation that is in
accordance  with the Welsh  Carson's  customary  practices and  consistent  with
compensation paid to directors in comparable public companies.

     Each of Daniel J. Thomas, Thomas A. Kiraly, James M. Greenwood,  Richard A.
Parr II, and W. Tom  Fogarty,  M.D.  have  entered  into  employment  agreements
between such individuals and Concentra.  The principal terms of these employment
agreements are as follows:

     o   each  agreement has a term of two years,  subject to automatic  renewal
         for additional one-year terms, unless terminated in accordance with the
         agreement's terms;

     o   each  agreement  provides for  compensation  consisting  of base salary
         amounts,  bonuses  at the  discretion  of the  board  of  directors  of
         Concentra and  participation in any employee benefit plan adopted by us
         for our employees;

     o   each  agreement  provides  for a severance  payment in the event of (1)
         termination  by Concentra  without  cause,  or (2)  resignation  by the
         employee for good reason;  consisting of two years' base salary for Mr.
         Thomas and one year's base salary for Messrs.  Greenwood,  Kiraly, Parr
         and Fogarty;  provided,  however, if termination by Concentra occurs on
         or before  August 17,  2000,  each  agreement  provides for a severance
         payment  consisting  of two and half year's base salary for Mr.  Thomas
         and two years' base salary for each of Messrs. Greenwood, Kiraly, Parr,
         and Fogarty.

Officers' and Directors' Indemnification Insurance

     The merger  agreement  provides  that,  for a period of six years after the
effective  time,  Concentra  will  indemnify  the present  and former  officers,
directors,   employees  and  agents  of  Concentra  and  its  subsidiaries  from
liabilities  arising out of actions or omissions in that  capacity  prior to the
effective time of the merger, to the full extent permitted under Delaware law or
as provided in Concentra's or its  subsidiaries'  organization  documents or any
written  indemnification  agreements.  In addition,  the  surviving  entity will
maintain  directors'  and officers'  insurance  coverage for six years after the
effective  time on terms no less  favorable  to such  indemnified  parties  than
existing insurance coverage, but Concentra will not be required to pay an annual
premium  in excess  of 200% of the last  premium  paid  prior to the date of the
merger agreement.

Employee Benefit Plans

1999 Long-Term Incentive Plan

General

     Concentra's  board and  stockholders  approved  its 1999  Stock  Option and
Restricted  Stock  Purchase  Plan in August 1999.  The purpose of the 1999 Stock
Plan is to promote the  interests  of  Concentra  and its  subsidiaries  and the
interests of our stockholders by providing an opportunity to selected  employees
and officers of Concentra and its  subsidiaries  and to other persons  providing
services to Concentra and its  subsidiaries to purchase  Concentra common stock.
By encouraging  such stock  ownership,  we seek to attract,  retain and motivate
such  employees  and other  persons and to encourage  such  employees  and other
persons to devote  their best efforts to our  business  and  financial  success.
Under  the 1999  Stock  Plan,  we may  grant  incentive  stock  options  and non
qualified  stock options and  restricted  stock  purchase  awards to purchase an
aggregate of up to 3,750,000  shares of Concentra  common  stock.  The following
summary describes the principal features of the 1999 Stock Plan and is qualified
in its entirety by reference to the specific  provisions of the 1999 Stock Plan,
which  is  filed as an  exhibit  to the  registration  statement  of which  this
prospectus forms in part.

Description of 1999 Stock Plan

     Shares and Options  Subject to Plan.  The 1999 Stock Plan  provides for the
grant of options or awards to purchase an aggregate  3,750,000  shares of common
stock,  either  in the form of  incentive  stock  options  intended  to meet the
requirements  of  Section  422 of the  Code or  nonqualified  stock  options  or
restricted  stock purchase awards.  The 1999 Stock Plan includes  provisions for
adjustment of the number of shares of common stock available for grant of



                                       68
<PAGE>

award  thereunder  and in the  number  of  shares  of  common  stock  underlying
outstanding  options in the event of any stock splits,  stock dividends or other
relevant changes in the capitalization of Concentra.

     Eligibility.  Under the 1999 Stock Plan, employees, including officers, are
eligible to receive  grants of either  incentive  stock  options  structures  to
qualify  under  Section  422 of the Code,  or  nonqualified  stock  options  and
restricted  stock  purchase  awards,  both of which are not intended to meet the
requirements  of Code Section  422.  Non-employee  directors  are eligible to be
granted only nonqualified options and awards.

     Administration. Administration of the 1999 Stock Plan has been delegated to
the Compensation  Committee,  consisting  entirely of  "Non-Employee  Directors"
within the meaning of the  Exchange  Act,  and  "outside  directors"  within the
meaning of the Code. The  Compensation  Committee,  within the parameters of the
1999 Stock Plan,  has  authority  to  determine  to whom  options and awards are
granted.  All questions of  interpretation or application of the 1999 Stock Plan
are  determined by the  Compensation  Committee,  whose  decisions are final and
binding upon all participants.

     Terms of Options and Awards. Each option or award granted will be evidenced
by a stock option or restricted stock purchase agreement.

     The Compensation  Committee will fix the term and vesting provisions of all
options granted pursuant to the 1999 Stock Plan.

     The exercise price of incentive  stock options may not be less than 100% of
the fair market value of the shares of common stock,  as determined by the board
or the  Compensation  Committee,  as the case may be, on the date the  option is
granted.  The exercise price of non-qualified stock options may not be less than
100% of the fair  market  value of the  shares of  common  stock on the date the
option is granted. In addition, the aggregate fair market value of the shares of
stock with respect to which  incentive  stock  options are  exercisable  for the
first time by an optionee during any calendar year shall not exceed $100,000. In
addition,  no  incentive  stock  option shall be granted to an optionee who owns
more than 10% of the total  combined  voting  power for all  classes of stock of
Concentra,  unless the exercise  price is at least 110% of the fair market value
of the shares of common stock and the exercise period does not exceed 5 years.

     Restricted  stock purchase awards granted under the 1999 Stock Plan will be
in such amounts and at such times as determined by the  Compensation  Committee.
The purchase price, as well as the vesting  provisions,  of such awards shall be
determined by the Compensation Committee and the purchase price may be equal to,
less than or more than the fair market value of the shares of common stock to be
awarded.

     Term of the 1999 Stock  Plan.  The 1999 Stock Plan will  continue in effect
until August 17, 2009 unless terminated prior to such date by the board.

Certain Federal Income Tax Consequences of the 1999 Stock Plan

     The tax  consequences  of  incentive  stock  options,  non-qualified  stock
options and restricted stock purchase awards are quite complex.  Therefore,  the
description of tax consequences set forth below is necessarily general in nature
and does not purport to be complete.  Moreover, statutory provisions are subject
to  change,  as are their  interpretations,  and their  application  may vary in
individual  circumstances.  Finally, the tax consequences under applicable state
and local  income tax laws may not be the same as under the  federal  income tax
laws.

     Incentive  stock  options  granted  pursuant  to the  1999  Stock  Plan are
intended to qualify as "incentive  stock options"  within the meaning of Section
422 of the Code. If an optionee does not dispose of the shares acquired pursuant
to exercise of an incentive  stock option  within one year after the transfer of
such shares to the  optionee  and within two years from grant of the option such
optionee will  recognize no taxable  income as a result of the grant or exercise
of such option.  However, for alternative minimum tax purposes the optionee will
recognize as an item of tax preference  the  difference  between the fair market
value of the shares received upon exercise and the exercise  price.  Any gain or
loss that is  subsequently  recognized upon a sale or exchange of the shares may
be treated by the  optionee as long-term  capital gain or loss,  as the case may
be. Concentra will not be entitled to a deduction for fed-

                                       69
<PAGE>


eral income tax purposes  with  respect to the  issuance of an  incentive  stock
option,  the  transfer  of shares upon  exercise  of the option of the  ultimate
disposition  of  such  shares  provided  the  holding  period  requirements  are
satisfied.

     If shares  received upon exercise of an incentive stock option are disposed
or prior to  satisfaction  of the  holding  period  requirements,  the  optionee
generally  will recognize  taxable  ordinary  income,  in the year in which such
disqualifying  disposition  occurs,  in an amount equal to the lesser of (1) the
excess of the fair market  value of the shares on the date of exercise  over the
exercise  price,  and (2) the gain recognized on such  disposition.  Such amount
will  ordinarily be  deductible by Concentra for federal  income tax purposes in
the same year,  provided that the company  satisfies  certain federal income tax
information  reporting  requirements.  In addition,  the excess,  if any, of the
amount realized by the exercise of the incentive stock option will be treated as
capital gain, long-term or short-term,  depending on whether,  after exercise of
the option, the shares were held for more than one year.

     Non-qualified  stock  options may be granted  under the 1999 Stock Plan. An
optionee  generally  will not  recognize  any  taxable  income  upon  grant of a
non-qualified stock option. The optionee will recognize taxable ordinary income,
at the time of exercise of such option,  in an amount equal to the excess of the
fair market value of the shares on the date of exercise over the exercise price.
Such amount will ordinary be deductible by Concentra in the same year,  provided
that  Concentra  satisfies  certain  federal  income tax  information  reporting
requirements.  Any gain or loss that is subsequently  recognized by the optionee
upon a sale or exchange of the shares will be capital gain or loss, long-term or
short-term,  depending on whether,  after the exercise of the option, the shares
were held for more than one year prior to such sale or exchange.

     Restricted  stock purchase awards may also be granted  pursuant to the 1999
Stock Plan. A recipient of a restricted  stock purchase award generally will not
recognize taxable income upon the purchase of shares of restricted stock, unless
he or she  makes a timely  election  under  Section  83(b) of the  Code.  Such a
recipient,  however,  would  recognize  taxable  ordinary income and the holding
period  for such  shares  would  commence  at the time that such  shares  become
vested,  in amount equal to the excess of the fair market value of the shares at
the time over the purchase  price paid for such  shares.  If, on the other hand,
the  recipient  makes a timely  election  under Section  83(b),  he or she would
recognize  taxable  ordinary income and the holding period for such shares would
commence at the time of  purchase,  in an amount equal to the excess of the fair
market  value of the  shares  at that  time,  determined  without  regard to any
transfer  restrictions  imposed  on  the  shares,   vesting  provisions  or  any
restrictions  imposes by the securities  laws,  over the purchase price paid for
such shares.  In either case,  Concentra should be entitled to a deduction in an
amount equal to the ordinary income recognized by the recipient in the same year
that the recipient  recognized such income,  provided that the company satisfies
certain federal income tax information reporting requirements.  Any gain or loss
that is subsequently  recognized by the recipient upon a sale or exchange of the
shares will be capital  gain or loss,  long-term  or  short-term,  depending  on
whether  the  shares  were  held for more  than one year  prior to such  sale or
exchange.

 401(k) Plan

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

Employee Stock Purchase Plan

     Until March 2, 1999,  Concentra  maintained an Employee Stock Purchase Plan
that permitted  substantially all employees to acquire Concentra 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  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,  Concentra  terminated the Employee Stock
Purchase  Plan.  The final  period for which  participating  employees  acquired
shares of  Concentra's  common stock began on January 1, 1999 and ended March 2,
1999.

                             PRINCIPAL STOCKHOLDERS

     After  the  merger  and  related  transactions,   all  of  the  issued  and
outstanding  capital  stock of Concentra  Operating is owned by  Concentra.  The
table  below  contains   information   regarding  the  beneficial  ownership  of
Concentra's common stock as of September 30, 1999 by

     o   each  stockholder  who  owns  beneficially  five  percent  or  more  of
         Concentra's common stock,

     o   each director of Concentra,

     o   each executive officer and

     o   all directors and officers as a group.

     The number of shares  beneficially  owned by each stockholder,  director or
officer  is  determined  according  to the  rules  of the  Commission,  and  the
information is not necessarily  indicative of beneficial ownership for any other
purpose.  Under current rules,  beneficial  ownership  includes any shares as to
which the  individual  or entity has sole or shared  voting power or  investment
power.  As a consequence,  several  persons may be deemed to be the  "beneficial
owners" of the same  shares.  Unless  otherwise  noted in the  footnotes to this
table,  each of the  stockholders  named  in this  table  has  sole  voting  and
investment   power  with  respect  to  the  Concentra  common  shares  shown  as
beneficially  owned. The percentage  ownership of each stockholder is calculated
based on 25,676,498 shares outstanding as of September 30, 1999.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Equity Investor Agreements

     Purchase Agreement

     In connection with its investment in Yankee,  Ferrer Freeman entered into a
subscription  agreement to purchase  1,854,545 shares of Yankee's Class A common
stock immediately prior to the merger, representing approximately 7% of Yankee's
outstanding  capital  stock.  The Class A common stock of Yankee is identical in
all respects to Yankee's  common stock except that the holders of Class A common
stock are entitled to elect one member to Yankee's  board of  directors.  In the
merger,  these shares of Yankee's  Class A common stock were  converted  into an
equal number of shares of Class A common stock of Concentra with the same rights
as Yankee's Class A common stock prior to the merger.

     In connection with their  investment in Yankee,  the Welsh Carson investors
and the other  investors  entered  into a  subscription  agreement  to  purchase
23,821,953  shares of Yankee's  common  stock  immediately  prior to the merger,
representing  approximately  93% of Yankee's  outstanding  capital stock. In the
merger,  these  shares of Yankee's  common  stock were  converted  into an equal
number of shares of  Concentra  common  stock with the same  rights as  Yankee's
common stock prior to the merger.

     Stockholders Agreement

     The  Welsh  Carson  investors,  the other  investors,  Ferrer  Freeman  and
Concentra also entered into a stockholders agreement. The stockholders agreement
does not provide for any agreements with the Welsh Carson  investors,  the other
investors,  and Ferrer Freeman with respect to voting of shares or management of
Concentra. The stockholders agreement provides for:

     o   limitations on the transfer of shares owned by the investors;

     o   tag along rights for Ferrer Freeman, the other investors, and the Welsh
         Carson  investors,  other than Welsh Carson, to participate in proposed
         dispositions of Concentra common stock by Welsh Carson;

     o   in the event that Welsh Carson receives a third party offer to purchase
         a significant portion of the outstanding  Concentra common stock, Welsh
         Carson may require Ferrer Freeman,  the Welsh Carson  investors and the
         other  investors to accept the offer and sell their shares of Concentra
         to the third party; and

     o   preemptive rights to the investors to participate,  on a pro rata basis
         according  to their  ownership of Concentra  capital  stock,  in equity
         offerings of Concentra with certain customary exceptions.

     Registration Rights Agreement

     At the same time they executed the stockholders agreement, the Welsh Carson
investors,  the other  investors,  Ferrer  Freeman and Concentra  entered into a
registration  rights  agreement.  The  registration  rights  agreement gives the
investors  rights to require  Concentra  to register  their  shares of Concentra
capital  stock under the  Securities  Act and to include,  upon  request,  their
shares in any other registration of shares by Concentra.

The Merger and Discount Debentures

     Welsh Carson  controlled  Yankee prior to the merger.  Messrs.  Queally and
Paul, who are members of the general  partner of Welsh Carson,  may be deemed to
have controlled Yankee prior to the merger.  For a description of the merger see
"The Transactions and Use of Proceeds."

     In addition,  WCAS Capital  Partners III,  L.P., an investment  partnership
affiliated  with Welsh  Carson,  bought $83.9  million face amount of 14% senior
discount debentures due 2010 of Concentra and warrants to acquire 619,356 shares
of Concentra  common stock for $42.7 million at the time of the merger.  Messrs.
Queally  and Paul,  who are  members  of the  general  partner  of WCAS  Capital
Partners III, L.P., may be deemed to control WCAS Capital Partners III, L.P. See
"The Transactions and Use of Proceeds."

Other Related Party Transactions

     Lois E.  Silverman,  who was a director of Concentra until August 17, 1999,
is one of the trustees and beneficiaries of Colonial Realty Trust,  which leases
twelve offices to Concentra for an annual  aggregate  consideration of $700,000.
We believe that the rental  rates paid to Colonial  Realty Trust are fair market
rental rates.

     W. Tom Fogarty, M.D., an executive officer of Concentra,  is the President,
a director and a member of Occupational  Health Centers of the Southwest,  P.A.,

$119,091,000  in  management  fees to  Concentra  in 1998  under its  management
agreement.

                       DESCRIPTION OF CERTAIN INDEBTEDNESS

The Senior Credit Facilities

     In connection with the merger,  Concentra Operating entered into the senior
credit  facilities  with a syndicate of financial  institutions  for which Chase
Securities  Inc. and DLJ Capital  Funding,  Inc. acted as Co-Lead  Arrangers and
Joint Book Managers. The Chase Manhattan Bank acted as Administrative Agent. DLJ
Capital Funding, Inc. acted as Syndication Agent. Credit Suisse First Boston and
Fleet National Bank acted as Co-Documentation Agents. The following is a summary
of the material  terms and  conditions  of the senior credit  facilities  and is
subject to the  detailed  provisions  of the senior  credit  facilities  and the
various  related  documents  entered into in  connection  with the senior credit
facilities.

     Borrower.  The borrower  under the senior credit  facilities  was Concentra
Operating.

     Loans; Interest Rates. The senior credit facilities consist of:

     (1) the term loan facilities consisting of:

         o    a 7 year $250.0 million tranche B term loan facility, and

         o    an 8 year $125.0 million tranche C term loan facility, and

     (2) the  revolving  credit  facility of up to $100.0  million,  including a
         letter of credit sub-facility of $25.0 million.

     The borrowings under the term loan facilities,  together with the aggregate
net  proceeds  from the  offering  of old notes  and the  offering  of  discount
debentures,  the equity  contributions and the our remaining cash at the time of
the merger were used to fund the transactions. In addition, the revolving credit
facility  will  provide   financing   for  future   working   capital,   capital
expenditures, acquisitions and other general corporate purposes.

     The revolving  credit facility will be available on a revolving basis until
September  30,  2005.  At  Concentra   Operating's  option,  the  senior  credit
facilities will bear interest at either:

     (1) the greater of (a) The Chase  Manhattan  Bank's  prime rate and (b) the
         Federal Funds Effective Rate plus 0.005% plus an additional:

         o    1.75% for the revolving credit facility,

         o    2.25% for the tranche B term loan facility, and

         o    2.50% for the tranche C term loan facility, or

     (2) the reserve-adjusted Eurodollar rate plus:

         o    2.75% for the revolving credit facility,

         o    3.25% for the tranche B term loan facility, and

         o    3.50% for the tranche C term loan facility;

provided,  that the above rate for the revolving  credit  facility is subject to
adjustment based on changes in Concentra  Operating's  leverage ratios effective
four fiscal  quarters  after the closing of the senior  credit  facilities.  The
default  rate under the senior  credit  facilities  is 2.0% above the  otherwise
applicable rate.

     Maturity of Loans.  The revolving  credit facility will mature on September
30,  2005.  The term loan  facilities  will  amortize  over seven  years for the
tranche  B term  loan  facility  and  eight  years  for the  tranche C term loan
facility.

                                       75
<PAGE>

     The  tranche  B term  loan  facility  will  be  payable  in 24  consecutive
quarterly  installments  of $625,000  beginning on September 30, 1999 until June
30, 2005.  Beginning on September 30, 2005,  Concentra  Operating  will pay four
consecutive  quarterly  installments of $58,750,000 until final maturity on June
30, 2006.

     The  tranche  C term  loan  facility  will  be  payable  in 28  consecutive
quarterly  installments  of $312,500  beginning on September 30, 1999 until June
30, 2006.  Beginning on September 30, 2006,  Concentra  Operating  will pay four
consecutive  quarterly  installments of $29,062,500 until final maturity on June
30, 2007.

     Security. The senior credit facilities are secured by a first-priority lien
on:

     o   100% of the issued and outstanding capital stock of Concentra Operating
         held by Concentra;

     o   100% of the  issued  and  outstanding  capital  stock of the direct and
         indirect  subsidiaries  of  Concentra  Operating,  other than its joint
         ventures; and

     o   all other  present  and  future  assets  and  properties  of  Concentra
         Operating and its subsidiaries, other than its joint ventures.

     Guarantors.  The senior credit  facilities  are guaranteed by Concentra and
each  of  Concentra   Operating's   present  and  future   direct  and  indirect
subsidiaries, other than its joint ventures.

     Prepayments.   In  addition,  the  senior  credit  facilities  provide  for
mandatory repayments,  subject to stated exceptions, of the Term Loan Facilities
and  reductions in the  revolving  credit  facility,  based on certain net asset
sales  outside the ordinary  course of business of Concentra  Operating  and its
subsidiaries,  from the net proceeds of specified debt and equity issuances, and
excess cash flow.  Outstanding  loans  under the senior  credit  facilities  are
voluntarily  pre-payable without penalty;  provided,  however, that we will bear
any Eurodollar rate breakage costs.

     Representations  and  Warranties.  The  senior  credit  facilities  contain
representations and warranties customary for similar credit facilities.

     Affirmative  Covenants.  The senior credit facilities  contain  affirmative
covenants customary for similar credit facilities.

     Negative Covenants. The senior credit facilities contain negative covenants
that limit the ability of  Concentra  Operating  and its  subsidiaries  to among
other things:

     o   incur  additional   indebtedness  or  contingent   obligations,   issue
         guarantees or enter into operating leases;

     o   grant liens or negative pledges;

     o   make  fundamental  changes in their  business,  corporate  structure or
         capital  structure,  including,  among other things,  entering into any
         merger,  consolidation or amalgamation,  or liquidating,  winding up or
         dissolving itself;

     o   sell assets;

     o   make specified restricted payments;

     o   make capital expenditures;

     o   make  investments,  including  the  advancing of loans or extensions of
         credit;  or enter into joint ventures,  or make  acquisitions of assets
         constituting a business unit or the capital stock of another entity;

                                       76
<PAGE>

     o   prepay, redeem or repurchase subordinated  indebtedness,  including the
         notes,  or amend documents  relating to other existing  indebtedness or
         other material documents; and

     o   enter into transactions with affiliates.

     Financial  Covenants.  The senior credit  facilities also contain financial
covenants requiring Concentra Operating to maintain:

     o   a maximum leverage ratio;

     o   a minimum interest coverage ratio; and

     o   a minimum fixed charge coverage ratio.

     Events of Default.  The senior  credit  facilities  also contain  events of
default that are typical of similar  credit  facilities  and  appropriate in the
context of the transactions,  including without  limitation,  subject to certain
exceptions, those related to:

     o   default in payment of principal and interest;

     o   materially incorrect representations or warranties;

     o   default in  observance  or  performance  of any of the  affirmative  or
         negative   covenants   included  in  the  senior   credit   facilities'
         documentation or in the related security documents;

     o   cross-default  in  payment  of other  indebtedness  of more than  $10.0
         million;

     o   specified events of bankruptcy;

     o   specified ERISA events;

     o   specified judgments or decrees involving more than $5.0 million;

     o   the failure of the applicable  senior credit facility  documents or any
         material  provisions  of  those  documents,  the  guarantees,  security
         documents or any related  documents to be enforceable and in full force
         and effect;

     o   certain change of control events;

     o   the conduct of Concentra's business; and

     o   the  failure  of the  subordination  of the  notes  and the  subsidiary
         guarantees  to the right of  payment  of the  lenders  under the senior
         credit facilities to be valid.

The Discount Debentures

     Concentra  raised  approximately  $110.0 million of the funds  necessary to
consummate the transactions  through the issuance of the discount  debentures in
the private capital markets.  The discount  debentures were issued with warrants
to  purchase  5.85% of  Concentra  common  stock at a  nominal  exercise  price.
Concentra is not required to pay any interest on the discount  debentures  until
2004. The discount debentures:

     o   mature on August 15, 2010;

     o   are structurally  subordinated to the senior credit  facilities and the
         notes;

                                       77
<PAGE>

     o   have registration rights;

     o   are redeemable by Concentra after August 15, 2000;

     o   are  redeemable by Concentra at the option of the holders upon a change
         of control; and

     o   subject Concentra and its subsidiaries to customary  covenants for this
         type of financing,  including restrictions on indebtedness,  dividends,
         liens,  affiliate  transactions,  stock  repurchases,  assets sales and
         mergers.

     In addition,  the discount  debentures bear non-cash  interest at a rate of
14% per annum until August 15, 2004.  On February  15, 2005,  and on  subsequent
interest  payment dates,  Concentra will also pay to the holders of the discount
debentures  that  amount  that is  necessary  to ensure the current and full tax
deductibility of the accrued discount on the discount  debentures.  That initial
amount is expected to be approximately $95.0 million. Subsequent amounts are not
expected to be material.  The indenture  with respect to the notes provides that
all such  payments  by  Concentra  will not be  payments  of cash  interest  for
purposes  of  clause  (10)  of  the  second  paragraph  under   "Description  of
Notes--Certain  Covenants--Restricted  Payments." If Concentra is unable to make
such  payment,  there  will  not be an  event  of  default  under  the  discount
debentures  indenture,  rather the interest rate on the discount debentures will
increase by 100 basis points until such payment is made.  After August 15, 2004,
interest at the rate of 14% per annum will be payable  semi-annually  in cash on
the discount debentures.

                          DESCRIPTION OF THE NEW NOTES

     The old notes were,  and the new notes will be,  issued  under an indenture
dated August 17, 1999 among  Concentra  Operating,  Health  Services and Managed
Care Services, and United States Trust Company of New York, as trustee.

     The new notes are the same as the old notes except that the new notes will:

     o   have a new CUSIP number;

     o   not bear any legends restricting their transfer; and

     o   not contain  certain  terms  providing  for an increase in the interest
         rate  under the  circumstances  described  in the  registration  rights
         agreement.

     The following  description  is a summary of the material  provisions of the
indenture.  It does not restate that  agreement in its entirety.  We urge you to
read the indenture because it, and not this  description,  define your rights as
holders of these notes.

     In this description of the new notes, we use terms in this section that are
defined under the caption "--Certain Definitions."

Brief Description of the Notes and the Subsidiary Guarantees

     The Notes. The notes are:

     o   general unsecured obligations of Concentra Operating;

     o   subordinated  in right of payment  to all  existing  and future  Senior
         Indebtedness of Concentra Operating;

     o   senior or pari  passu in right of payment  to all  existing  and future
         subordinated Indebtedness of Concentra Operating; and

     o   unconditionally guaranteed by the Guarantors.

                                       78

     The Subsidiary Guarantees. These notes are jointly and severally guaranteed
by each Restricted Subsidiary of Concentra Operating, except the Permitted Joint
Ventures.

     The Subsidiary Guarantees of these notes:

     o   are general unsecured obligations of each Guarantor;

     o   are  subordinated in right of payment to all existing and future Senior
         Indebtedness of each Guarantor; and

     o   are senior or pari passu in right of payment to all existing and future
         subordinated Indebtedness of each Guarantor.

     Assuming  Concentra  Operating had completed the offering of the old notes,
applied the net  proceeds as intended and had  completed  the merger with Yankee
and  related  transactions  as of June 30,  1999,  Concentra  Operating  and the
Guarantors  would have had total Senior  Indebtedness  of  approximately  $379.0
million.  As indicated  above and as discussed in detail below under the caption
"--Subordination,"  payments  on the notes and under the  Subsidiary  Guarantees
will be subordinated to the payment of Senior  Indebtedness.  The indenture will
permit  Concentra  Operating  and the  Guarantors  to  incur  additional  Senior
Indebtedness.

     As of August 17,  1999,  all of  Concentra  Operating's  Subsidiaries  were
"Restricted  Subsidiaries."  However,  under the  circumstances  described below
under  the  caption   "--Certain   Covenants--Designation   of  Restricted   and
Unrestricted  Subsidiaries,"  Concentra Operating will be permitted to designate
certain of Concentra  Operating's  subsidiaries as "Unrestricted  Subsidiaries."
Unrestricted  Subsidiaries  will  not be  subject  to  many  of the  restrictive
covenants in the  indenture.  Unrestricted  Subsidiaries  will not guarantee the
notes.

Principal, Maturity and Interest

     The notes:

     o   will be  limited  to a  maximum  aggregate  principal  amount of $190.0
         million;

     o   will mature on August 15, 2009;

     o   will be issued in  denominations  of $1,000 and  integral  multiples of
         $1,000;

     o   will bear interest at the rate of 13% per annum.

     Interest  will be paid  semi-annually  on February 15 and August 15 of each
year, beginning on February 15, 2000, to the holder of record on the immediately
preceding February 1 and August 1.

     Interest  will be  computed  on the basis of a 360-day  year  comprised  of
twelve 30-day months.

Methods of Receiving Payments on the Notes

     If a holder has given wire transfer  instructions  to Concentra  Operating,
Concentra  Operating will make all principal,  premium and interest  payments on
the holder's notes in accordance with those instructions.  All other payments on
the notes will be made at the office or agency of the paying agent and registrar
within the City and State of New York unless Concentra  Operating elects to make
interest  payments by check mailed to the holders at their  address set forth in
the register of holders.

Subordination

     The payment of principal  of, any premium and interest on the notes will be
subordinated  to the prior payment in full of all Concentra  Operating's  Senior
Indebtedness.

                                       79
<PAGE>

     The holders of Senior  Indebtedness  will be entitled to receive payment in
full  in  cash  of  all  amounts  due or to  become  due in  respect  of  Senior
Indebtedness before the holders of notes will be entitled to receive any payment
with   respect  to  the  notes,   except  that  holders  of  notes  may  receive
Reorganization  Securities and payments made from the trust  described under the
caption  "--Legal  Defeasance  and  Covenant  Defeasance,"  in the  event of any
distribution to Concentra  Operating's  creditors  pursuant to any Insolvency or
Liquidation Proceeding with respect to Concentra Operating.

     Upon  any  such  Insolvency  or  Liquidation  Proceeding,  any  payment  or
distribution  of  assets  of  Concentra   Operating  of  any  kind,  other  than
Reorganization  Securities,  will  be  paid  by  Concentra  Operating  or by any
receiver,   liquidating   trustee  or  other  person   making  such  payment  or
distribution,  or by the  holders of the notes or by the  trustee if received by
them, directly to the holders of Senior Indebtedness, or their representative or
representatives,  for the  payment  of the  Senior  Indebtedness  until all such
Senior Indebtedness has been paid in full in cash.

     Concentra  Operating also may not make any payment in respect of the notes,
except in Reorganization Securities, if:

     o   a payment  default  on  Designated  Senior  Indebtedness  occurs and is
         continuing; or

     o   the  trustee  receives  a  notice  from the  agent  bank  under  one of
         Concentra  Operating's  senior credit  facilities or the holders or the
         representative of any Designated Senior Indebtedness  indicating that a
         default has occurred that permits the holders of that  indebtedness  to
         accelerate its maturity.

     Payments on the notes may and will be resumed:

     o   in the case of a payment  default,  upon the date on which such default
         is cured or waived; and

     o   in case of a nonpayment default, the earlier of

         (1)  the date on which such nonpayment default is cured or waived;

         (2)  179  days  after  the  date on  which  the  applicable  notice  is
              received; or

         (3)  the date on which the  trustee  receives  written  notice from the
              agent  bank  or the  representative  for  such  Designated  Senior
              Indebtedness,  as the  case  may  be,  rescinding  the  applicable
              notice,  unless the maturity of any Designated Senior Indebtedness
              has been accelerated.

     No new notice of default  may be  delivered  unless and until 181 days have
elapsed since the effectiveness of the immediately prior notice.

     No event of default that existed or was  continuing on the date of delivery
of any such  notice  to the  trustee  shall  be,  or be made,  the  basis  for a
subsequent  notice  unless  such  default  shall have been cured or waived for a
period of not less than 90 days.

     As a result of the subordination  provisions  described above, in the event
of a bankruptcy,  liquidation or reorganization of Concentra Operating,  holders
of these notes may recover less ratably  than  creditors of Concentra  Operating
who are holders of Senior Indebtedness.  See "Risk Factors--Risks  Applicable to
the  Notes--Subordination."  Concentra Operating and its Restricted Subsidiaries
will be subject to certain  financial  tests  limiting the amount of  additional
Indebtedness,  including Senior  Indebtedness,  that Concentra Operating and its
Restricted  Subsidiaries  can incur.  See  "--Certain  Covenants--Incurrence  of
Indebtedness and Issuance of Preferred Stock."

Subsidiary Guarantees

     The  Guarantors  will  jointly  and  severally   guarantee,   on  a  senior
subordinated  basis,  Concentra  Operating's  obligations  under the notes. Each
Subsidiary Guarantee will be subordinated to the prior payment in full of all

                                       80
<PAGE>


Senior  Indebtedness of that Guarantor.  The obligations of each Guarantor under
its Subsidiary Guarantee will be limited as necessary to prevent that Subsidiary
Guarantee from  constituting a fraudulent  conveyance  under applicable law. See
"Risk Factors--Fraudulent Conveyance Matters."

     A Guarantor may not sell or otherwise  dispose of all or substantially  all
of its assets,  or consolidate  with or merge with or into,  whether or not such
Guarantor is the surviving person, another person unless:

     o   immediately  after  giving  effect to that  transaction,  no Default or
         Event of Default exists; and

     o   either:

         (1)  the person  acquiring the property in any such sale or disposition
              or the person  formed by or surviving  any such  consolidation  or
              merger assumes all the obligations of that Guarantor pursuant to a
              supplemental indenture satisfactory to the trustee; or

         (2)  the Net Proceeds of such sale or other  disposition are applied in
              accordance with the applicable provisions of the indenture.

     The Subsidiary Guarantee of a Guarantor will be released:

     o   in  connection   with  any  sale  or  other   disposition   of  all  or
         substantially all of the assets of that Guarantor,  including by way of
         merger  or  consolidation,  if  Concentra  Operating  applies  the  Net
         Proceeds  of that  sale or other  disposition  in  accordance  with the
         applicable provisions of the indenture;

     o   in connection  with the sale of all of the Capital Stock of a Guarantor
         if  Concentra  Operating  applies  the Net  Proceeds  of  that  sale in
         accordance with the applicable provisions of the indenture; or

     o   if Concentra Operating  designates any Restricted  Subsidiary that is a
         Guarantor as an Unrestricted Subsidiary.

     The Net  Proceeds of an Asset Sale may be used by  Concentra  Operating  to
make an offer to holders for the repurchase of notes.  See  "--Repurchase at the
Option of Holders--Asset Sales."

Optional Redemption

     General.  After August 15, 2004,  Concentra  Operating  may redeem all or a
part of these notes, upon not less than 30 nor more than 60 days' notice, at the
redemption prices, expressed as percentages of principal amount, set forth below
plus accrued and unpaid interest on the new notes, to the applicable  redemption
date, if redeemed during the  twelve-month  period beginning on August 15 of the
years indicated below:

                     Year                                     Percentage
                     ----                                     ----------
                     2004...................................  106.500%
                     2005...................................  104.875%
                     2006...................................  103.250%
                     2007...................................  101.625%
                     2008 and thereafter....................  100.000%

     Upon  Equity  Offerings.  At any time prior to August 15,  2002,  Concentra
Operating  may  on one  or  more  occasions  redeem  up to 25% of the  aggregate
principal amount of notes originally  issued under the indenture at a redemption
price of 113% of the  principal  amount of the notes,  plus  accrued  and unpaid
interest  to the  redemption  date,  with the net cash  proceeds  of one or more
Equity Offerings; provided that:

     o   at  least  75% of the  aggregate  principal  amount  of  notes  remains
         outstanding  immediately  after  the  occurrence  of  such  redemption,
         excluding notes held by Concentra Operating and its Subsidiaries; and

                                       81
<PAGE>


     o   the redemption  must occur within 90 days of the date of the closing of
         such Equity Offering.

     Except  pursuant  to  the  preceding  paragraphs,  the  notes  will  not be
redeemable at Concentra Operating's option prior to August 15, 2004.

     Selection  and Notice.  If less than all of the notes are to be redeemed at
any time, the trustee will select notes for redemption as follows:

     o   if the notes are listed,  in compliance  with the  requirements  of the
         principal national  securities  exchange on which the notes are listed;
         or

     o   if the notes are not so listed,  on a pro rata basis, by lot or by such
         method as the trustee shall deem fair and appropriate.

     No notes of $1,000 or less shall be redeemed in part. Notices of redemption
shall be mailed by first class mail at least 30 but not more than 60 days before
the  redemption  date to each holder of notes to be  redeemed at its  registered
address. Notices of redemption may not be conditional.

     If any note is to be redeemed in part only,  the notice of redemption  that
relates to that note shall  state the  portion  of the  principal  amount of new
notes to be  redeemed.  A new note in principal  amount equal to the  unredeemed
portion  of the  original  note will be issued in the name of the  holder of new
notes upon cancellation of the original note. Notes called for redemption become
due on the date fixed for redemption. On and after the redemption date, interest
ceases to accrue on notes or portions of them called for redemption.

Mandatory Redemption

     Except  as set forth  under  the  caption  "--Repurchase  at the  Option of
Holders,"  we are not  required to make  mandatory  redemption  or sinking  fund
payments with respect to the notes.

Repurchase at the Option of Holders

     Change of Control. If a Change of Control occurs, each holder of notes will
have the right to require  Concentra  Operating to  repurchase  all or any part,
equal to $1,000 or an  integral  multiple  of  $1,000,  of that  holder's  notes
pursuant  to the  Change of  Control  Offer.  In the  Change of  Control  Offer,
Concentra Operating will offer a Change of Control Payment in cash equal to 101%
of the  aggregate  principal  amount of notes  repurchased  plus any accrued and
unpaid  interest on the notes to the date of purchase.  Within 60 days following
any Change of  Control,  Concentra  Operating  will mail a notice to each holder
describing the transaction or transactions that constitute the Change of Control
and offering to repurchase notes on the Change of Control Payment Date, being no
later than five  business  days after the  termination  of the Change of Control
Offer,  pursuant to the  procedures  required by the  indenture and described in
such  notice.  Concentra  Operating  will  comply with the  requirements  of the
Exchange Act and any other  securities  laws and  regulations  thereunder to the
extent  such  laws  and  regulations  are  applicable  in  connection  with  the
repurchase of the notes as a result of a Change of Control.

     On the Change of Control  Payment Date,  Concentra  Operating  will, to the
extent lawful:

     o   accept for payment all notes or portions of new notes properly tendered
         pursuant to the Change of Control Offer;

     o   deposit  with the paying agent an amount equal to the Change of Control
         Payment in respect of all notes or portions of notes so tendered; and

     o   deliver or cause to be  delivered  to the trustee the notes so accepted
         together with an Officers'  Certificate stating the aggregate principal
         amount of notes or  portions  of notes  being  purchased  by  Concentra
         Operating.

                                       82
<PAGE>

     The paying agent will promptly mail to each holder of notes so tendered the
Change  of  Control  Payment  for such  notes,  and the  trustee  will  promptly
authenticate  and mail, or cause to be transferred by book entry, to each holder
a new note equal in  principal  amount to any  unpurchased  portion of any notes
surrendered;  provided that each such new note will be in a principal  amount of
$1,000 or an integral multiple of $1,000.

     Prior to complying with any of the provisions of this  "--Repurchase at the
Option of Holders--Change of Control" covenant,  but in any event within 90 days
following  a Change  of  Control,  Concentra  Operating  will  either  repay all
outstanding  Senior  Indebtedness  or obtain any requisite  consents,  under all
agreements governing outstanding Senior Indebtedness to permit the repurchase of
notes required by this covenant.  Concentra Operating will publicly announce the
results of the Change of Control  Offer on or as soon as  practicable  after the
Change of Control Payment Date.

     The provisions  described above that require Concentra  Operating to make a
Change of  Control  Offer  following  a Change  of  Control  will be  applicable
regardless  of  whether  or  not  any  other  provisions  of the  indenture  are
applicable.  Except as described above with respect to a Change of Control,  the
indenture  does not contain  provisions  that permit the holders of the notes to
require that Concentra Operating  repurchase or redeem the notes in the event of
a takeover, recapitalization or similar transaction.

     Concentra Operating's  outstanding Senior Indebtedness  currently prohibits
Concentra  Operating from  purchasing any notes,  and also provides that certain
change of control events with respect to Concentra  and/or  Concentra  Operating
would   constitute  a  default  under  the   agreements   governing  the  Senior
Indebtedness.  Any future  credit  agreements  or other  agreements  relating to
Senior  Indebtedness  to which Concentra  Operating  becomes a party may contain
similar restrictions and provisions.  In the event a Change of Control occurs at
a time when Concentra  Operating is prohibited from purchasing notes,  Concentra
Operating  could seek the consent of its senior lenders to the purchase of notes
or could attempt to refinance the borrowings that contain such  prohibition.  If
Concentra  Operating  does not obtain  such a consent or repay such  borrowings,
Concentra  Operating will remain prohibited from purchasing notes. In such case,
Concentra  Operating's  failure to purchase  tendered notes would  constitute an
Event of Default under the indenture which would, in turn,  constitute a default
under  such  Senior  Indebtedness.  In  such  circumstances,  the  subordination
provisions in the  indenture  would likely  restrict  payments to the holders of
notes.

     Concentra  Operating will not be required to make a Change of Control Offer
upon a Change of Control if a third party  makes the Change of Control  Offer in
the manner,  at the times and otherwise in compliance with the  requirements set
forth in the indenture applicable to a Change of Control Offer made by Concentra
Operating and purchases all notes validly  tendered and not withdrawn under such
Change of Control Offer.

     The definition of Change of Control includes a phrase relating to the sale,
lease,  transfer,  conveyance or other disposition of "all or substantially all"
of the assets of  Concentra  Operating  and its  Subsidiaries  taken as a whole.
Although  there  is  a  limited  body  of  case  law   interpreting  the  phrase
"substantially  all," there is no precise  established  definition of the phrase
under applicable law.  Accordingly,  the ability of a holder of notes to require
Concentra  Operating  to  repurchase  such  notes as a result of a sale,  lease,
transfer,  conveyance  or other  disposition  of less than all of the  assets of
Concentra  Operating and its Subsidiaries  taken as a whole to another person or
group may be uncertain.

     Asset Sales.  Concentra  Operating will not, and will not permit any of its
Restricted Subsidiaries to, complete an Asset Sale unless:

     (1) Concentra Operating or the Restricted  Subsidiary,  as the case may be,
         receives consideration at the time of such Asset Sale at least equal to
         the fair market value of the assets or Equity  Interests issued or sold
         or otherwise disposed of;

     (2) such fair market value is determined by Concentra  Operating's board of
         directors  and  evidenced by a resolution of the board of directors set
         forth in an officers'  certificate  delivered  to the trustee  provided
         that the board of directors'  determination must be based on an opinion
         issued  by an  accounting,  appraisal  or  investment  banking  firm of
         national standing if such fair market value exceeds $35 million; and



                                       83
<PAGE>

   (3)   at least 75% of the  consideration  received by Concentra  Operating or
         such Restricted  Subsidiary is in the form of cash or Cash Equivalents.
         For purposes of this  provision,  each of the following shall be deemed
         to be cash:

         o    any  liabilities,   as  shown  on  Concentra  Operating's  or  the
              Restricted  Subsidiary's  most recent balance sheet,  of Concentra
              Operating  or any  Restricted  Subsidiary,  other than  contingent
              liabilities and liabilities  that are by their terms  subordinated
              to the notes or any Subsidiary Guarantee,  that are assumed by the
              transferee  of any such assets  pursuant  to a customary  novation
              agreement  that releases  Concentra  Operating or such  Restricted
              Subsidiary from further liability; and

         o    any securities,  notes or other obligations  received by Concentra
              Operating or any such  Restricted  Subsidiary from such transferee
              that  are   contemporaneously,   subject  to  ordinary  settlement
              periods,  converted  by  Concentra  Operating  or such  Restricted
              Subsidiary  into cash or Cash  Equivalents,  to the  extent of the
              cash received in that conversion.

     The 75%  limitation  referred  to above will not apply to any Asset Sale in
which  the  cash or Cash  Equivalents  portion  of the  consideration  received,
determined in accordance  with the  preceding  sentence,  is equal to or greater
than what the  after-tax  proceeds  would have been had such Asset Sale complied
with the 75% limitation.

     Within 270 days after the receipt of any Net  Proceeds  from an Asset Sale,
Concentra  Operating  or any  such  Restricted  Subsidiary  may  apply  such Net
Proceeds, at its option:

     (1) to repay or repurchase  Senior  Indebtedness of Concentra  Operating or
         any Restricted Subsidiary;

     (2) to acquire all or substantially all the assets of, or a majority of the
         Voting Stock of, another Permitted Business;

     (3) to make a capital expenditure in a Permitted Business;

     (4) to acquire other assets, other than securities, that are used or useful
         in a Permitted Business; or

     (5) to make an Asset  Sale  Offer,  treating  the Net  Proceeds  as  Excess
         Proceeds for all purposes.

     Any Net  Proceeds  from Asset  Sales that are not  applied or  invested  as
provided in the preceding  paragraph will constitute  excess proceeds.  When the
aggregate  amount  of these  excess  proceeds  exceeds  $15  million,  Concentra
Operating  will be required to make an offer to all holders of notes to purchase
the maximum  principal  amount of notes that may be purchased  out of the excess
proceeds.  The  offer  price  in any  such  offer  will be  equal to 100% of the
principal  amount plus any accrued and unpaid  interest to the date of purchase,
and will be payable in cash. Any excess proceeds which remain after consummation
of such an offer,  may be used by  Concentra  Operating  for  general  corporate
purposes. If the aggregate principal amount of notes tendered into such an offer
exceeds the amount of excess proceeds,  the trustee shall select the notes to be
purchased on a pro rata basis. Upon completion of each such offer, the amount of
excess proceeds shall be reset at zero.

Certain Covenants

     Restricted Payments.  Concentra Operating will not, and will not permit any
of its Restricted  Subsidiaries to, directly or indirectly,  make any Restricted
Payment  unless,  at the time of and  after  giving  effect  to such  Restricted
Payment:

     (1) no Default or Event of Default shall have occurred and be continuing or
         would occur as a consequence of such Restricted Payment;



                                       84
<PAGE>

     (2) Concentra  Operating  would not be permitted to incur at least $1.00 of
         additional  Indebtedness  pursuant to the Fixed Charge  Coverage  Ratio
         test set forth in the first  paragraph of the covenant  described below
         under the caption "--Certain  Covenants--Incurrence of Indebtedness and
         Issuance of Preferred Stock"; and

     (3) such  Restricted  Payment,  together with the  aggregate  amount of all
         other  Restricted   Payments  made  by  Concentra   Operating  and  its
         Restricted  Subsidiaries  after August 17, 1999,  excluding  Restricted
         Payments  permitted by clauses (1) through (6), (12),  (14) and (15) of
         the  next  succeeding   paragraph,   is  less  than  the  sum,  without
         duplication, of:

         (a)  50% of the Consolidated Net Income of Concentra  Operating for the
              period,  taken as one accounting period, from the beginning of the
              first full fiscal quarter  commencing after August 17, 1999 to the
              end of Concentra  Operating's  most recently  ended fiscal quarter
              for which internal financial  statements are available at the time
              of such Restricted  Payment,  or, if such  Consolidated Net Income
              for such period is a deficit, less 100% of such deficit; plus

         (b)  100% of the  aggregate net  proceeds,  including  the  fair-market
              value of property other than cash, received by Concentra Operating
              as a contribution to Concentra  Operating's capital or received by
              Concentra  Operating  from the issue or sale since August 17, 1999
              of  Equity   Interests   of   Concentra   Operating,   other  than
              Disqualified Stock, or of Disqualified Stock or debt securities of
              Concentra  Operating  that have been  converted  into such  Equity
              Interests,  other than Equity Interests,  or Disqualified Stock or
              debt  securities,  sold to a  Restricted  Subsidiary  of Concentra
              Operating and other than  Disqualified  Stock or convertible  debt
              securities that have been converted into Disqualified Stock; plus

         (c)  to the extent that any Restricted  Investment  that was made after
              August 17, 1999 is sold for cash or otherwise liquidated or repaid
              for cash, the lesser of

              o   the cash  return of capital  with  respect to such  Restricted
                  Investment, less any cost of disposition, and

              o   the initial amount of such Restricted Investment; plus

         (d)  the amount by which  Indebtedness  of  Concentra  Operating or its
              Restricted   Subsidiaries  is  reduced  on  Concentra  Operating's
              balance sheet upon the conversion or exchange subsequent to August
              17, 1999 of any Indebtedness of Concentra Operating convertible or
              exchangeable for Equity Interests,  other than Disqualified Stock,
              of  Concentra  Operating,  less the  amount of any cash,  or other
              property,  distributed  by Concentra  Operating or any  Restricted
              Subsidiary upon such conversion or exchange; plus

         (e)  if any  Unrestricted  Subsidiary  pays any cash  dividends or cash
              distributions  to  Concentra  Operating  or any of its  Restricted
              Subsidiaries,   100%  of  any   such   cash   dividends   or  cash
              distributions made after August 17, 1999.

     So long as no Default has  occurred  and is  continuing  or would be caused
thereby, the preceding provisions will not prohibit:

     (1) the  payment  of any  dividend  within  60 days  after  the date of its
         declaration,  if at said date of  declaration  such payment  would have
         complied with the provisions of the indenture;

     (2) the redemption, repurchase, retirement, defeasance or other acquisition
         of any Indebtedness or Equity  Interests of Concentra  Operating or its

         proceeds of, the substantially  concurrent sale or issuance, other than
         to a subsidiary of Concentra  Operating,  of, other Equity Interests of
         Concentra Operating,  other than Disqualified Stock;  provided that the
         amount  of any such  net  cash  proceeds  that  are  utilized  for such
         redemption,  repurchase,  retirement,  defeasance or other  acquisition
         shall be excluded from clause (3)(b) of the preceding paragraph;

         organizational  documents for, and  agreements  among holders of Equity

         of  such  redemption,   repurchase,  acquisition  or  retirement,  such

         agreements  or other  agreements to  compensate  management  employees;
         provided that such  redemptions or repurchases  pursuant to this clause
         will not exceed $2 million in any calendar year with unused  amounts in
         any calender  year being  carried  over to  succeeding  calendar  years
         subject to a maximum of $10 million in any calendar year; provided that

         Stock of Concentra  Operating or Concentra,  in an aggregate amount not
         to exceed $5 million  at any one time  outstanding;  provided  that the
         amount of any such payments will be included in subsequent calculations
         of the amount of Restricted Payments;

         payments will be included in subsequent  calculations  of the amount of
         Restricted Payments;

    (10) if  immediately  before and  immediately  after giving them effect,  no
         Default or Event of Default has occurred and Concentra  Operating would
         have been permitted to incur at least $1.00 of additional  Indebtedness
         pursuant to the Fixed Charge Coverage Ratio test set forth in the first
         paragraph of the covenant  described below under the caption "--Certain
         Covenants--Incurrence of Indebtedness and Issuance of Preferred Stock",
         payments of cash  dividends  to Concentra  in an amount  sufficient  to
         enable Concentra to make semi-annual  payments after August 15, 2004 of
         cash interest not in excess of 14% per annum on the principal amount of
         Concentra  Senior  Discount  Debentures,  provided  that  Concentra  is
         otherwise  unable to pay such  interest and such  dividends are applied
         directly to the payment of such interest;  and provided  further,  that
         the  amount  of any  such  payments  will  be  included  in  subsequent
         calculations of the amount of Restricted Payments,  see "Description of
         Certain Indebtedness--The Holdco Notes";

    (11) if  immediately  before and  immediately  after giving them effect,  no

         version,  acquisition  or retirement  of our 6.0% and 4.5%  convertible
         subordinated  notes in accordance with their respective terms in effect
         on August 17, 1999;  provided that the amount of any such payments will
         be  included in  subsequent  calculations  of the amount of  Restricted
         Payments;

    (12) payments to  Concentra  in an amount  equal to the amount of income tax
         that  Concentra  Operating and the Restricted  Subsidiaries  would have
         paid had they filed  consolidated  tax  returns  on a separate  company
         basis in any given  year,  less the  amount of such taxes paid or to be
         paid directly by Concentra  Operating and the  Restricted  Subsidiaries
         for such years;

    (13) an amount  not to exceed  $1.0  million  in any  fiscal  year to permit
         Concentra to pay:

         (a)  franchise  taxes and other fees  required  to  maintain  its legal
              existence; and

         (b)  its corporate overhead expenses incurred in the ordinary course of
              business,  its audit  expenses,  any filing  fees  required by the
              Commission and to pay salaries or other  compensation of employees
              who perform services for both Concentra and Concentra Operating;

         provided  that the  amount of any such  payments  will be  included  in
         subsequent calculations of the amount of Restricted Payments;

    (14) Permitted Investments;

    (15) distributions to fund the merger with Yankee and related  transactions;
         and

    (16) other  Restricted  Payments  in an  aggregate  amount  not to exceed $5
         million at any one time;  provided that the amount of any such payments
         will be included in subsequent calculations of the amount of Restricted
         Payments.

     The amount of all Restricted  Payments,  other than cash, shall be the fair
market value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by Concentra  Operating or such Subsidiary,
as the case may be, pursuant to the Restricted Payment. The fair market value of
any non-cash  Restricted  Payment shall be determined in good faith by the board
of directors whose  resolution  shall be delivered to the trustee.  The board of
directors' determination must be based upon an opinion or appraisal issued by an
accounting,  appraisal or investment  banking firm of national  standing if such
fair market  value  exceeds $20  million.  Not later than the date of making any
Restricted  Payment,  Concentra  Operating  shall  deliver  to  the  trustee  an
officers'  certificate  stating that such  Restricted  Payment is permitted  and
setting  forth  the  basis  upon  which the  calculations  required  by this "--
Restricted  Payments"  covenant  were  computed,  together  with a  copy  of any
fairness opinion or appraisal required by the indenture.

     Incurrence  of  Indebtedness  and  Issuance of Preferred  Stock.  Concentra
Operating will not, and will not permit any of its  Subsidiaries to, directly or
indirectly,  Incur any  Indebtedness,  including  Acquired  Debt,  and Concentra
Operating will not issue any Disqualified  Stock or preferred stock and will not
permit any of its Restricted  Subsidiaries  to issue any  Disqualified  Stock or
preferred stock.

     Despite the above,  Concentra Operating may Incur  Indebtedness,  including
Acquired  Debt,  or issue  Disqualified  Stock or preferred  stock and Concentra
Operating's Restricted  Subsidiaries may Incur Indebtedness,  including Acquired
Debt,  and issue  Disqualified  Stock or  preferred  stock if the  Fixed  Charge
Coverage  Ratio for Concentra  Operating's  most recently ended four full fiscal
quarters for which  internal  financial  statements  are  available  immediately
preceding  the date on which such  additional  Indebtedness  is Incurred or such
Disqualified Stock or preferred stock is issued:

     (1) for such dates from August 17, 1999 up to but not  including  September
         30, 2000, would have been at least 2 to 1;

                                       87
<PAGE>


     (2) for such dates from  September 30, 2000 up to but not  including  March
         31, 2001, would have been at least 2.25 to 1; and

     (3) after March 31, 2001 would have been at least 2.50 to 1;

each  determined on a pro forma basis,  on the assumption  that the net proceeds
from the additional Indebtedness had been received, or the Disqualified Stock or
preferred  stock had been issued,  as the case may be, at the  beginning of such
four-quarter period.

     The above will not prohibit the Incurrence of any of the following items of
Indebtedness:

     (l) Indebtedness and letters of credit of Concentra Operating or any of its
         Restricted  Subsidiaries  pursuant  to our  senior  credit  facilities;
         provided that the  aggregate  amount of all  Indebtedness  of Concentra
         Operating  and the  Guarantors  outstanding  under  our  senior  credit
         facilities  after giving effect to such  incurrence  does not exceed an
         amount equal to $475 million at any one time;

     (2) Existing   Indebtedness  of  Concentra  Operating  and  its  Restricted
         Subsidiaries;

     (3) Indebtedness of Concentra  Operating and the Guarantors  represented by
         the notes and the Subsidiary Guarantees;

     (4) Indebtedness   of  Concentra   Operating  or  any  of  its   Restricted
         Subsidiaries   represented  by  Capital  Lease  Obligations,   mortgage
         financings or purchase money obligations, in each case incurred for the
         purpose of financing  all or any part of the purchase  price or cost of
         construction or improvement of property, plant or equipment used in the
         business of Concentra Operating or such Restricted Subsidiary,  whether
         through  the  direct  purchase  of assets or the  Capital  Stock of any
         person owning such Assets, in an aggregate principal amount or accreted
         value,   as  applicable,   not  to  exceed  $15  million  at  any  time
         outstanding;

     (5) Permitted Refinancing Indebtedness of Concentra Operating or any of its
         Restricted  Subsidiaries  in exchange for, or the net proceeds of which
         are used to  refund,  refinance  or  replace  Indebtedness,  other than
         intercompany  Indebtedness,  that was  permitted by the indenture to be
         incurred  under the first  paragraph of this covenant or clauses (3) or
         (14) of this paragraph;

     (6) Indebtedness  between  Concentra  Operating  and any of its  Restricted
         Subsidiaries or between any of its Restricted  Subsidiaries;  provided,
         however, that:

         (a)  if  Concentra  Operating  or any  Guarantor is the obligor on such
              Indebtedness,  such Indebtedness must be expressly subordinated to
              the prior payment in full in cash of all Obligations  with respect
              to  the  notes,  in  the  case  of  Concentra  Operating,  or  the
              Subsidiary  Guarantee  of  such  Guarantor,   in  the  case  of  a
              Guarantor; and

         (b)  o   any subsequent  issuance or transfer of Equity  Interests that
                  results in any such Indebtedness  being held by a person other
                  than  Concentra   Operating  or  a   wholly-owned   Restricted
                  Subsidiary and

              o   any  sale or other  transfer  of any  such  Indebtedness  to a
                  person   that  is  not  either   Concentra   Operating   or  a
                  wholly-owned Restricted Subsidiary

              shall be deemed, in each case, to constitute an Incurrence of such
              Indebtedness by Concentra Operating or such Restricted Subsidiary,
              as the case may be, that was not permitted by this clause (6);

     (7) Hedging  Obligations  of Concentra  Operating or any of its  Restricted
         Subsidiaries  that are for the  purpose of hedging  interest  rate risk
         with respect to any Indebtedness  that is permitted by the terms of the
         indenture to be outstanding;

                                       88
<PAGE>


     (8) the  Guarantee  by  Concentra   Operating  or  any  of  its  Restricted
         Subsidiaries  of  Indebtedness  of Concentra  Operating or a Restricted
         Subsidiary  of  Concentra  Operating  that  was  permitted  by  another
         provision of this covenant;

     (9) Non-Recourse Debt of Concentra Operating's  Unrestricted  Subsidiaries;
         provided,   however,  that  if  any  such  Indebtedness  ceases  to  be
         Non-Recourse  Debt of an Unrestricted  Subsidiary,  such event shall be
         deemed to  constitute an  Incurrence  of  Indebtedness  by a Restricted
         Subsidiary of Concentra Operating that was not permitted by this clause
         (9);

     (10)Indebtedness   of  Concentra   Operating  or  any  of  its   Restricted
         Subsidiaries  constituting  reimbursement  obligations  with respect to
         letters of credit issued in the ordinary course of business,  including
         without  limitation  to  letters  of  credit  in  respect  of  workers'
         compensation  claims  or  self-insurance,  or other  Indebtedness  with
         respect  to   reimbursement   type   obligations   regarding   workers'
         compensation claims;  provided,  however, that upon the drawing of such
         letters  of  credit  or  the  incurrence  of  such  Indebtedness,  such
         obligations  are  reimbursed  within 30 days  following such drawing or
         incurrence;

     (11)Indebtedness  arising  from  agreements  of  Concentra  Operating  or a
         Restricted  Subsidiary  providing  for  indemnification,  adjustment of
         purchase  price or  similar  obligations,  in each  case,  incurred  or
         assumed in connection  with the  disposition of any business,  asset or
         Subsidiary,  other than  guarantees  of  Indebtedness  incurred  by any
         person  acquiring  all or any  portion  of  such  business,  assets  or
         Subsidiary  for the purpose of  financing  such  acquisition;  provided
         that:

         (a)  such  Indebtedness  is not  reflected  on  the  balance  sheet  of
              Concentra  Operating  or  any  Restricted  Subsidiary,  contingent
              obligations  referred to in a footnote or  footnotes  to financial
              statements  and not otherwise  reflected on the balance sheet will
              not be deemed to be reflected  on such balance  sheet for purposes
              of this clause (a); and

         (b)  the maximum  aggregate  liability in respect of such  Indebtedness
              shall at no time  exceed the gross  proceeds,  including  non-cash
              proceeds  (the fair market value of such non-cash  proceeds  being
              measured at the time  received  and without  giving  effect to any
              such subsequent  changes in value) actually  received by Concentra
              Operating  and/or such  Restricted  Subsidiary in connection  with
              such disposition;

     (12)obligations  in respect of  performance,  surety and similar  bonds and
         completion guarantees provided by Concentra Operating or any Restricted
         Subsidiary in the ordinary course of business;

     (13)Indebtedness  arising  from the  honoring by a bank or other  financial
         institution of a check, draft or similar instrument, except in the case
         of  daylight  overdrafts,  drawn  against  insufficient  funding in the
         ordinary course of business,  provided, however, that such Indebtedness
         is extinguished within five business days of incurrence; and

     (14)additional Indebtedness of Concentra Operating or any of its Restricted
         Subsidiaries,  including  Attributable  Debt incurred  after August 17,
         1999,  in  an  aggregate   principal  amount,  or  accreted  value,  as
         applicable,   at  any  time   outstanding,   including   all  Permitted
         Refinancing  Indebtedness incurred to refund,  refinance or replace any
         other Indebtedness incurred pursuant to this clause (14), not to exceed
         $25 million.

     For   purposes   of   determining    compliance    with   this   "--Certain
Covenants-Incurrence  of Indebtedness and Issuance of Preferred Stock" covenant,
in the event that an item of proposed  Indebtedness  meets the  criteria of more
than one of the  categories of permitted  debt  described in clauses (1) through
(14)  above or  pursuant  to the first  paragraph  of this  covenant,  Concentra
Operating will be permitted to classify such item of  Indebtedness in any manner
that complies with this covenant.  In addition,  Concentra Operating may, at any
time, change the  classification  of an item of Indebtedness,  or any portion of
Indebtedness,  to any other clause or to the first  paragraph  of this  covenant
provided  that  Concentra  Operating  would be  permitted  to Incur such item of
Indebtedness,  or the portion of Indebtedness,  pursuant to such other clause or
the first paragraph of this covenant, as the case may be, at such time

                                       89

of reclassification.  Accrual of interest, accretion or amortization of original
issue  discount and the accretion of accreted  value will not be deemed to be an
Incurrence of Indebtedness for purposes of this covenant.

     Liens.  Concentra  Operating  will  not,  and  will not  permit  any of its
Restricted  Subsidiaries  to  Incur  or  become  effective  any Lien of any kind
securing  trade  payables,  Attributable  Debt or  Indebtedness  that  does  not
constitute  Senior  Indebtedness,  other than Permitted Liens, upon any of their
property or assets, now owned or hereafter acquired unless:

     o   in  the  case  of  Liens  securing   Indebtedness   that  is  expressly
         subordinated or junior in right of payment to the notes,  the notes are
         secured on a senior basis to the obligations so secured until such time
         as such obligations are no longer secured by a Lien; and

     o   in all other cases, the notes are secured on an equal and ratable basis
         with the obligations so secured until such time as such obligations are
         no longer secured by a Lien.

     Dividend and Other Payment Restrictions Affecting Restricted  Subsidiaries.
Concentra  Operating  will  not,  and  will  not  permit  any of its  Restricted
Subsidiaries  to,  directly or  indirectly,  create or permit to exist or become
effective any consensual encumbrance or consensual restriction on the ability of
any Restricted Subsidiary to:

     o   pay dividends or make any other distributions to Concentra Operating or
         any of its Restricted Subsidiaries (a) on its Capital Stock or (b) with
         respect to any other interest or participation  in, or measured by, its
         profits;

     o   pay any  Indebtedness  owed to Concentra  Operating or any of Concentra
         Operating's Restricted Subsidiaries;

     o   make loans or  advances  to  Concentra  Operating  or any of  Concentra
         Operating's Restricted Subsidiaries; or

     o   transfer any of its properties or assets to Concentra  Operating or any
         of Concentra Operating's Restricted Subsidiaries.

     However,  the  preceding  restrictions  will not apply to  encumbrances  or
restrictions existing under or by reason of:

     o   any encumbrance or restriction pursuant to an agreement in effect at or
         entered into on August 17, 1999, including:

         (1)  our senior  credit  facilities as in effect as of August 17, 1999,
              and  any  amendments,   modifications,   restatements,   renewals,
              increases, supplements,  refundings,  replacements or refinancings
              of  those  credit  facilities,   provided  that  such  amendments,
              modifications,  restatements,  renewals,  increases,  supplements,
              refundings,  replacements or refinancings are no more restrictive,
              taken as a whole,  as  determined  in the good faith  judgment  of
              Concentra  Operating's  board of  directors,  with respect to such
              dividend and other payment  restrictions  than those  contained in
              our senior credit facilities as in effect on August 17, 1999; and

         (2)  the indenture and the notes;

     o   any applicable law, rule, regulation or order;

     o   any  instrument  governing  Indebtedness  or Capital  Stock of a person
         acquired by Concentra  Operating or any of its Restricted  Subsidiaries
         as in effect at the time of such  acquisition,  (except  to the  extent
         incurred in connection with or in  contemplation  of such  acquisition,
         which  encumbrance or  restriction is not applicable to any person,  or
         the properties or assets of any person,  other than the person,  or the
         property or



                                       90
<PAGE>

         assets  of the  person,  so  acquired,  provided  that,  in the case of
         Indebtedness,  such  Indebtedness  was  permitted  by the  terms of the
         indenture to be incurred;

     o   customary  non-assignment  provisions  in  leases  entered  into in the
         ordinary course of business and consistent with past practices;

     o   any  Purchase   Money  Note  or  other   Indebtedness   or  contractual
         requirements   incurred  with  respect  to  a  Qualified   Receiveables
         Transaction  relating exclusively to a Receiveables Entity that, in the
         good  faith  determination  of the  board  of  directors  of  Concentra
         Operating,   are  necessary  to  effect  such  Qualified   Receiveables
         Transaction;

     o   purchase money obligations for property acquired in the ordinary course
         of business that impose restrictions on the property so acquired of the
         nature described in the last clause of the preceding paragraph;

     o   restrictions  with  respect  solely  to  a  Restricted   Subsidiary  of
         Concentra  Operating  imposed pursuant to a binding agreement which has
         been entered into for the sale or disposition  of all or  substantially
         all of the  Capital  Stock or  assets  of such  Restricted  Subsidiary,
         provided  that such  restrictions  apply solely to the Capital Stock or
         assets being sold of such Restricted Subsidiary;

     o   provisions with respect to the disposition or distribution of assets or
         property in connection  with Permitted  Joint Ventures  entered into in
         accordance with past practice made in the ordinary course of business;

     o   Permitted   Refinancing   Indebtedness,   provided  that  the  material
         restrictions  contained  in the  agreements  governing  such  Permitted
         Refinancing  Indebtedness  are no more  restrictive,  in the good faith
         judgment of Concentra Operating's board of directors, taken as a whole,
         to the  holders  of  notes  than  those  contained  in  the  agreements
         governing the Indebtedness being refinanced; and

     o   restrictions  on  cash  or  other  deposits  or net  worth  imposed  by
         customers  under  contracts  entered  into in the  ordinary  course  of
         business.

     Merger, Consolidation or Sale of Assets. Concentra Operating may not:

     o   consolidate  or  merge  with or into  another  person,  whether  or not
         Concentra Operating is the surviving corporation; or

     o   sell,  assign,  transfer,   convey  or  otherwise  dispose  of  all  or
         substantially  all of its properties or assets,  in one or more related
         transactions, to another person unless:

         (1)  either:

              (a) Concentra Operating is the surviving corporation; or

              (b) the person  formed by or surviving any such  consolidation  or
                  merger,  if other than Concentra  Operating,  or to which such
                  sale,  assignment,  transfer,  conveyance or other disposition
                  shall have been made is a  corporation  organized  or existing
                  under the laws of the United  States,  any state of the United
                  States or the District of Columbia;

         (2)  the  person  formed  by or  surviving  any such  consolidation  or
              merger, if other than Concentra Operating,  or the person to which
              such sale, assignment,  transfer,  conveyance or other disposition
              shall have been made  expressly  assumes  all the  obligations  of
              Concentra  Operating under the notes and the indenture pursuant to
              a supplemental indenture in a form reasonably  satisfactory to the
              trustee;

         (3)  immediately  after giving pro forma effect to such  transaction no
              Default or Event of Default exists; and


                                       91
<PAGE>


         (4)  Concentra  Operating  or person  formed by or  surviving  any such
              consolidation or merger, if other than Concentra Operating,  or to
              which  such  sale,  assignment,   transfer,  conveyance  or  other
              disposition shall have been made;

              (a) will,  after giving pro forma  effect to such  merger,  on the
                  assumption  that  it  had  occurred  at the  beginning  of the
                  applicable four-quarter period, be permitted to incur at least
                  $1.00 of additional  Indebtedness pursuant to the Fixed Charge
                  Coverage  Ratio test set forth in the first  paragraph  of the
                  covenant   described  above  under  the  caption  "--  Certain
                  Covenants   --Incurrence  of  Indebtedness   and  Issuance  of
                  Preferred Stock"; or

              (b) would,  together  with  its  Restricted  Subsidiaries,  have a
                  higher  Fixed Charge  Coverage  Ratio  immediately  after such
                  merger,  after giving pro forma effect to such merger,  on the
                  assumption  that  it  had  occurred  at the  beginning  of the
                  applicable four-quarter period, than the Fixed Charge Coverage
                  Ratio of Concentra Operating and its Subsidiaries  immediately
                  prior to the transaction.

     The preceding clause (4) will not prohibit:

              (a) a  merger  between  Concentra  Operating  and  a  wholly-owned
                  Subsidiary; or

              (b) a  merger  between   Concentra   Operating  and  an  Affiliate
                  incorporated   solely  for  the  purpose  of   reincorporating
                  Concentra Operating in another state of the United States;

     so long as, in each case, the amount of Indebtedness of Concentra Operating
and its Restricted Subsidiaries is not increased thereby.

     In addition, Concentra Operating may not, directly or indirectly, lease all
or  substantially  all of its  properties  or  assets,  in one or  more  related
transactions,  to any other  person.  This  covenant will not be applicable to a
sale, assignment, transfer, conveyance or other disposition of assets between or
among Concentra Operating and any of its wholly-owned Restricted Subsidiaries.

     Transactions  with Affiliates.  Concentra  Operating will not, and will not
permit any of its Restricted  Subsidiaries to engage in an Affiliate Transaction
unless:

     (1) such  Affiliate  Transaction  is on terms that are no less favorable to
         Concentra  Operating or the relevant  Restricted  Subsidiary than those
         that would have been obtained in a comparable  transaction by Concentra
         Operating or such Restricted  Subsidiary made on an arm's-length  basis
         with an unrelated person; and

     (2) Concentra Operating delivers to the trustee:

         (a)  with  respect to any  Affiliate  Transaction  or series of related
              Affiliate Transactions involving aggregate consideration in excess
              of $5 million, a resolution of the board of directors set forth in
              an   officers'   certificate   certifying   that  such   Affiliate
              Transaction complies with clause (1) above and that such Affiliate
              Transaction  has been approved by a majority of the  disinterested
              members of the board of directors; and

         (b)  with  respect to any  Affiliate  Transaction  or series of related
              Affiliate Transactions involving aggregate consideration in excess
              of $15  million,  an opinion as to the  fairness to the holders of
              such Affiliate  Transaction  from a financial point of view issued
              by an accounting, appraisal or investment banking firm of national
              standing.

     The following items shall not be deemed to be Affiliate  Transactions  and,
therefore, will not be subject to the provisions of the prior paragraph:

     (1) customary  directors' fees to persons who are not otherwise  Affiliates
         of Concentra Operating;



                                       92
<PAGE>

     (2) transactions between or among Concentra Operating and/or its Restricted
         Subsidiaries;

     (3) the payment of Affiliate  Management  Fees in an amount in any calendar
         year not to exceed the greater of:

         (a)  $1 million; and

         (b)  1% of Consolidated EBITDA;

     (4) payments by Concentra  Operating or any of its Restricted  Subsidiaries
         to Welsh Carson,  Ferrer Freeman and their  respective  Affiliates made
         for any:

         (a)  financial advisory, financing, underwriting or placement services;
              or

         (b)  in  respect of other  investment  banking  activities,  including,
              without   limitation,   in   connection   with   acquisitions   or
              divestitures;

         which payments are approved in good faith by a majority of the board of
         directors  of  Concentra  Operating  or a  committee  of the  board  of
         directors consisting of disinterested members;

     (5) loans or advances to employees in accordance with past practice made in
         the ordinary  course of business  which are approved in good faith by a
         majority  of  the  board  of  directors  of  Concentra  Operating  or a
         committee  of  the  board  of  directors  consisting  of  disinterested
         members;

     (6) any  agreement as in effect on August 17, 1999 or any amendment to such
         agreement,  so long as any  such  amendment  is no  less  favorable  to
         Concentra Operating and its Restricted Subsidiaries;

     (7) the existence of, or the  performance by Concentra  Operating or any of
         its Restricted  Subsidiaries of its obligations under the terms of, our
         agreement and plan of merger, registration rights agreement or purchase
         agreement  related to our merger with Yankee, to which it is a party on
         or after August 17, 1999; provided,  however, that the existence of, or
         the  performance  by  Concentra  Operating  or any  of  its  Restricted
         Subsidiaries  of  obligations  under any future  amendment  to any such
         existing  agreement or under any similar  agreement  entered into after
         August 17, 1999 shall only be permitted by this clause;

     (8) the payment of all fees and expenses  related to our merger with Yankee
         and related  transactions,  including  fees to Welsh  Carson and Ferrer
         Freeman;

     (9) any payment  pursuant to any tax sharing  agreement  between  Concentra
         Operating  and  Concentra  or any other  person  with  which  Concentra
         Operating is required or permitted to file a consolidated tax return or
         with which  Concentra  Operating is or could be part of a consolidated,
         combined or unitary group for tax  purposes;  provided that in no event
         shall the amount  permitted to be paid pursuant to all such  agreements
         exceed the tax liabilities  attributable  solely to Concentra Operating
         and its Restricted Subsidiaries (whether as a consolidated, combined or
         unitary group);

     (10)Restricted  Payments  that  are  permitted  by  the  provisions  of the
         indenture    described    above    under   the    caption    "--Certain
         Covenants--Restricted Payments";

     (11)customary  fees and  compensation  paid to, and  indemnity  provided on
         behalf of, officers,  directors,  employees or consultants of Concentra
         Operating or any of its Restricted Subsidiaries; and

     (12)any transaction involving ordinary course investment banking,  merchant
         banking, commercial banking or related activities.

     Despite the above, the holders of notes will be entitled to receive payment
in full in cash of all  amounts  due or to become  due in  respect  of the notes
before any payment is made with respect to Affiliate Management Fees in the



                                       93
<PAGE>

event of any distribution to creditors of Concentra  Operating in any Insolvency
or Liquidation  Proceeding with respect to Concentra  Operating.  No payments of
Affiliate  Management  Fees shall be made by  Concentra  Operating or any of its
Restricted  Subsidiaries  if the  Fixed  Charge  Coverage  Ratio  for  Concentra
Operating's  most recently  ended four full fiscal  quarters for which  internal
financial  statements  are  available  immediately  preceding  the date on which
Affiliate  Management  Fees  are to be paid is less  than  1.75 to 1;  provided,
however, that such payments due but not paid shall accrue and shall be paid only
after  such  time as the Fixed  Charge  Coverage  Ratio  for a four full  fiscal
quarter period is no longer less than or equal to 1.75 to 1.

     Designation  of  Restricted  and  Unrestricted  Subsidiaries.  The board of
directors  may  designate  any  Restricted  Subsidiary  to  be  an  Unrestricted
Subsidiary  if that  designation  would not  cause a  Default.  If a  Restricted
Subsidiary  is  designated  as  an  Unrestricted  Subsidiary,   all  outstanding
Investments owned by Concentra Operating and its Restricted Subsidiaries, except
to the extent repaid in cash, in the Subsidiary so designated  will be deemed to
be  Restricted  Payments  at the time of such  designation,  to the  extent  not
designated  a Permitted  Investment,  and will reduce the amount  available  for
Restricted  Payments under the first  paragraph of the covenant  described above
under  the  caption   "--Certain   Covenants--Restricted   Payments."  All  such
outstanding Investments will be valued at their fair market value at the time of
such  designation,  as determined in good faith by the board of directors.  That
designation will only be permitted if such Restricted Payment would be permitted
at that time and if such Restricted Subsidiary otherwise meets the definition of
an  Unrestricted  Subsidiary.   The  board  of  directors  may  redesignate  any
Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would
not cause a Default.

     Anti-Layering. Concentra Operating will not, and will not permit any of its
Restricted Subsidiaries to, Incur any Indebtedness that is both:

     (1) subordinate or junior in right of payment to any Senior Indebtedness;
         and

     (2) senior in any respect in right of payment to the notes.

     No Guarantor will Incur any Indebtedness that is both:

     (1) subordinate or junior in right of payment to any Senior Indebtedness of
         such Guarantor; and

     (2) senior in any respect in right of payment to the Subsidiary Guarantees.

     Sale and Leaseback Transactions. Concentra Operating will not, and will not
permit any of its Restricted  Subsidiaries to, enter into any sale and leaseback
transaction unless:

     (1) Concentra Operating or such Restricted Subsidiary could have:

         (a)  incurred  Indebtedness in an amount equal to the Attributable Debt
              relating to such sale and  leaseback  transaction  under the Fixed
              Charge  Coverage Ratio test in the first paragraph of the covenant
              described above under the caption "--Certain Covenants--Incurrence
              of Indebtedness and Issuance of Preferred Stock;" and

         (b)  incurred  a Lien  to  secure  such  Indebtedness  pursuant  to the
              covenant    described   above   under   the   caption   "--Certain
              Covenants--Liens;"

     (2) the gross cash proceeds of that sale and leaseback  transaction  are at
         least equal to the fair market  value,  as  determined in good faith by
         the  board  of  directors  and set  forth in an  officers'  certificate
         delivered to the trustee,  of the property  that is the subject of such
         sale and leaseback transaction; and

     (3) the  transfer  of  assets  in such sale and  leaseback  transaction  is
         permitted  by, and  Concentra  Operating  applies the  proceeds of such
         transaction in compliance with, the covenant  described above under the
         caption "-- Repurchase at the Option of Holders--Asset Sales."

                                       94
<PAGE>

     Limitation  on  Issuances  and  Sales of  Equity  Interests  in  Restricted
Subsidiaries.  Concentra  Operating  will not,  and will not  permit  any of its
Restricted  Subsidiaries to, transfer,  convey, sell, lease or otherwise dispose
of any Equity  Interests  in any  Restricted  Subsidiary  or to issue any of its
Equity  Interests,  other than,  if  necessary,  Equity  Interests  constituting
directors' qualifying shares, to any person except:

         (1)  to Concentra Operating or a wholly-owned Subsidiary,  other than a
              Receivables Entity; or

         (2)  in compliance with the covenant  described above under the caption
              "--Repurchase   at  the  Option  of   Holders--Asset   Sales"  and
              immediately  after giving  effect to such  issuance or sale,  such
              Restricted   Subsidiary   would   continue  to  be  a   Restricted
              Subsidiary.

     Despite the above, Concentra Operating may sell all the Equity Interests of
a Restricted  Subsidiary as long as Concentra  Operating complies with the terms
of the  covenant  described  under the  caption  "--Repurchase  at the Option of
Holders--Asset Sales."

     Limitations on Issuances of Guarantees of Indebtedness. Concentra Operating
will not permit any  Restricted  Subsidiary,  directly or  indirectly,  to Incur
Indebtedness  or  Guarantee  or pledge any  assets to secure the  payment of any
Indebtedness of Concentra  Operating or any Restricted  Subsidiary unless either
such Restricted Subsidiary:

     (1) is a Guarantor; or

     (2) simultaneously  executes and delivers a  supplemental  indenture to the
         indenture and becomes a Guarantor, which Guarantee shall:

         (a)  with  respect  to  any  Guarantee  of  Senior   Indebtedness,   be
              subordinated  in right of  payment  on the same terms as the notes
              are subordinated to such Senior Indebtedness; and

         (b)  with respect to any Guarantee of any other Indebtedness, be senior
              to  or  pari  passu  with  such  Restricted   Subsidiary's   other
              Indebtedness  or  Guarantee  of or  pledge to  secure  such  other
              Indebtedness.

     Despite the above,  any Subsidiary  Guarantee of the notes shall provide by
its  terms  that it shall be  automatically  and  unconditionally  released  and
discharged   under  the   circumstances   described   above  under  the  caption
"--Subsidiary  Guarantees."  The form of the  Guarantee  will be  attached as an
exhibit to the indenture.

     Additional  Guarantees.  If Concentra  Operating  shall acquire or create a
Restricted  Subsidiary  after August 17, 1999, or if any Subsidiary of Concentra
Operating becomes a Restricted  Subsidiary,  then such newly acquired or created
Restricted  Subsidiary,  other than a Permitted  Joint  Venture,  shall become a
Guarantor  and  execute a  supplemental  indenture  and  deliver  an  opinion of
counsel, in accordance with the terms of the indenture.

     Business Activities.  Concentra Operating will not, and will not permit any
Restricted  Subsidiary  to,  engage  in any  business  other  than  a  Permitted
Business.

     Advances to Subsidiaries.  All advances to Restricted  Subsidiaries made by
Concentra  Operating  after August 17, 1999 will be  evidenced  by  intercompany
notes in favor of Concentra  Operating.  Each  intercompany note will be payable
upon  demand and will bear  interest  at the same rate as the  notes.  A form of
intercompany note will be attached as an exhibit to the indenture.

     Payments for Consents.  Concentra  Operating  will not, and will not permit
any of its Subsidiaries to, directly or indirectly,  pay or cause to be paid any
consideration  to or  for  the  benefit  of any  holder  of  notes  for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of the  indenture or the notes unless such  consideration  is offered to be paid
and is paid to all holders of the notes that consent, waive or agree to amend in
the time frame set forth in the solicitation documents relating to such consent,
waiver or agreement.

     Reports.  Whether or not required by the  Commission,  so long as any notes
are  outstanding,  Concentra  Operating  will  furnish or make  available to the
holders of notes,  within the time periods  specified in the Commission's  rules
and regulations:

     (l) all quarterly and annual  financial  information that would be required
         to be contained in a filing with the  Commission on Forms 10-Q and 10-K
         if Concentra  Operating  were required to file such Forms,  including a
         "Management's  Discussion  and  Analysis  of  Financial  Condition  and
         Results of  Operations"  and,  with  respect to the annual  information
         only,  a  report  on  the  annual  financial  statements  by  Concentra
         Operating's certified independent accountants; and

     (2) all  current  reports  that  would be  required  to be  filed  with the
         Commission  on Form 8-K if Concentra  Operating  were  required to file
         such reports.

     If  Concentra   Operating  has  designated  any  of  its   Subsidiaries  as
Unrestricted  Subsidiaries,  then the quarterly and annual financial information
required  by  the  preceding  paragraph  shall  include  a  reasonably  detailed
presentation,  either  on  the  face  of  the  financial  statements  or in  the
accompanying  footnotes,  and in the  "Management's  Discussion  and Analysis of
Financial  Condition  and  Results  of  Operations"  section,  of the  financial
condition and results of operations  of Concentra  Operating and its  Restricted
Subsidiaries  separate from the financial condition and results of operations of
the Unrestricted Subsidiaries of Concentra Operating.

     In addition,  following this exchange offer, whether or not required by the
Commission,  Concentra  Operating  will file a copy of all the  information  and
reports  referred to in clauses (1) and (2) above with the Commission for public
availability  within the time periods  specified in the  Commission's  rules and
regulations  (unless the Commission will not accept such a filing) and make such
information  available to securities  analysts and  prospective  investors  upon
request.  In addition,  Concentra  Operating has agreed that, for so long as any
notes  remain  outstanding,  it will  furnish to the holders  and to  securities
analysts and prospective investors, upon their request, the information required
to be delivered pursuant to Rule 144A(d) (4) under the Securities Act.

Events of Default and Remedies

     Each of the following is an Event of Default under the indenture:

     (1) default  for 30 days in the  payment  when due of interest on the notes
         whether  or not  prohibited  by  the  subordination  provisions  of the
         indenture;

     (2) default in payment  when due of the  principal of or any premium on the
         notes, whether or not prohibited by the subordination provisions of the
         indenture;

     (3) failure by Concentra Operating to comply with the provisions  described
         under the captions  "--Repurchase  at the Option of  Holders-Change  of
         Control",   "--Repurchase  at  the  Option  of  Holders--Asset  Sales",
         "--Certain       Covenants-Restricted       Payments",       "--Certain
         Covenants--Incurrence  of Indebtedness and Issuance of Preferred Stock"
         or "--Certain Covenants--Merger, Consolidation or Sale of Assets";

     (4) failure  by  Concentra  Operating  for 60 days  after  notice  from the
         trustee  or holders  of at least 25% in  principal  amount of the notes
         then  outstanding  to comply  with any of its other  agreements  in the
         indenture or the notes;

     (5) default under any mortgage,  indenture or instrument  under which there
         may be  issued  or by which  there  may be  secured  or  evidenced  any
         Indebtedness for borrowed money or Guarantee by Concentra  Operating or
         any  of its  Restricted  Subsidiaries,  or  the  payment  of  which  is
         guaranteed   by   Concentra   Operating   or  any  of  its   Restricted
         Subsidiaries,  whether such Indebtedness or Guarantee now exists, or is
         created after August 17, 1999, if that default:

                                       96
<PAGE>


         (a)  is caused by a failure to pay  principal of or any premium on such
              Indebtedness  prior to the expiration of the grace period provided
              in such Indebtedness on the date of such default; or

         (b)  results  in the  acceleration  of such  Indebtedness  prior to its
              express maturity;

         and,  in each  case,  the  principal  amount of any such  Indebtedness,
         together with the principal amount of any other such Indebtedness under
         which  there has been a payment  default or the  maturity  of which has
         been so accelerated, aggregates $20 million or more;

     (6) failure by Concentra Operating or any of its Restricted Subsidiaries to
         pay  final  judgments  aggregating  in  excess  of $20  million,  which
         judgments are not paid, discharged or stayed for a period of 60 days;

     (7) except as permitted by the indenture,  any Subsidiary  Guarantee  which
         shall be held in any judicial proceeding to be unenforceable or invalid
         or shall  cease for any  reason to be in full  force and  effect or any
         Guarantor,  or any person acting on behalf of any Guarantor,  who shall
         deny or disaffirm its obligations under its Subsidiary Guarantee; and

     (8) certain  events of bankruptcy  or insolvency  with respect to Concentra
         Operating or any of its Restricted Subsidiaries.

     In the event of a declaration of acceleration of the notes because an Event
of Default has occurred and is continuing as a result of the acceleration of any
Indebtedness described in clause (5) of the preceding paragraph, the declaration
of acceleration of the notes shall be  automatically  annulled if the holders of
any  Indebtedness  described  in  clause  (5) of the  preceding  paragraph  have
rescinded the declaration of acceleration in respect of such Indebtedness within
30 days of the date of such declaration and if:

     o   the annulment of the  acceleration of notes would not conflict with any
         judgment or decree of a court of competent jurisdiction; and

     o   all  existing  Events of Default,  except  nonpayment  of  principal or
         interest  on  the  notes  that   became  due  solely   because  of  the
         acceleration of the notes, have been cured or waived.

     If any Event of  Default  occurs  and is  continuing,  the  trustee  or the
holders of at least 25% in principal amount of the outstanding notes may declare
the principal of the notes to be due and payable immediately;  provided, that so
long as any Indebtedness  permitted to be incurred pursuant to our senior credit
facilities shall be outstanding,  such acceleration shall not be effective until
the earlier of:

     o   an  acceleration  of any such  Indebtedness  under  our  senior  credit
         facilities; or

     o   five business  days after receipt by Concentra  Operating and the agent
         bank  to our  senior  credit  facilities  of  written  notice  of  such
         acceleration.

     If payment  of the notes is  accelerated  because  of an Event of  Default,
Concentra Operating shall promptly notify the holders of the Senior Indebtedness
of the acceleration.

     Despite the above,  in the case of an Event of Default arising from certain
events of bankruptcy or insolvency,  with respect to Concentra  Operating or any
of its  Subsidiaries,  the principal and any accrued but unpaid  interest on all
outstanding  notes shall  become due and  payable  immediately  without  further
action or notice.

     Holders of the notes may not enforce the  indenture  or the notes except as
provided in the indenture. Subject to certain limitations, holders of a majority
in principal amount of the then outstanding  notes may direct the trustee in its
exercise of any trust or power.  The trustee may  withhold  from  holders of the
notes notice of any continuing Default or Event of Default,  except a Default or
Event of  Default  relating  to the  payment of  principal  or  interest,  if it
determines that withholding notice is in their interest.

                                       97
<PAGE>

     In the case of any Event of Default  occurring on or after August 15, 2004,
by reason of any willful  action or inaction  taken or not taken by or on behalf
of Concentra  Operating  with the  intention of avoiding  payment of the premium
that Concentra  Operating would have had to pay if Concentra  Operating then had
elected to redeem the notes  pursuant to the optional  redemption  provisions of
the indenture,  an equivalent  premium shall also become and be immediately  due
and payable to the extent  permitted by law upon the  acceleration of the notes.
If an Event of Default  occurs prior to August 15, 2004 by reason of any willful
action, or inaction, taken, or not taken, by or on behalf of Concentra Operating
with the intention of avoiding the  prohibition on redemption of the notes prior
to August 15,  2004,  then the premium  specified  in the  indenture  shall also
become  immediately  due and  payable  to the extent  permitted  by law upon the
acceleration of the notes.

     The holders of a majority in aggregate  principal  amount of the notes then
outstanding  by notice to the trustee may on behalf of the holders of all of the
notes waive any existing Default or Event of Default and its consequences  under
the indenture except a continuing  Default or Event of Default in the payment of
interest or any premium on, or the principal of, the notes.

     Concentra  Operating  is  required  to  deliver to the  trustee  annually a
statement  regarding  compliance with the indenture.  Upon becoming aware of any
Default or Event of Default,  Concentra  Operating is required to deliver to the
trustee a statement specifying such Default or Event of Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

     No director,  officer,  employee,  incorporator or stockholder of Concentra
Operating,  or any  Guarantor,  as  such,  shall  have  any  liability  for  any
obligations  of  Concentra  Operating  or the  Guarantors  under the notes,  the
indenture,  the Subsidiary  Guarantees or for any claim based on, in respect of,
or by reason of, such  obligations  or their  creation.  Each holder of notes by
accepting a note waives and releases all such liability.  The waiver and release
are part of the  consideration  for issuance of the notes. The waiver may not be
effective to waive liabilities under the federal securities laws.

Legal Defeasance and Covenant Defeasance

     Concentra  Operating  may, at its option,  elect to completely  defease the
notes.  Such defeasance  means that all of its  obligations  with respect to the
outstanding  notes and all of the  obligations of the Guarantors with respect to
their Subsidiary Guarantees would be discharged, except for:

     o   the rights of  holders of  outstanding  notes to  receive  payments  in
         respect of the  principal  of, any premium  and  interest on such notes
         when such payments are due from the trust referred to below;

     o   Concentra Operating's  obligations with respect to the notes concerning
         issuing temporary notes,  registration of notes, mutilated,  destroyed,
         lost or stolen  notes and the  maintenance  of an office or agency  for
         payment and money for security payments held in trust;

     o   the rights,  powers,  trusts, duties and immunities of the trustee, and
         Concentra Operating's obligations in connection with the indenture; and

     o   the legal defeasance provisions of the indenture.

     In addition,  Concentra  Operating  may, at its option,  elect to defease a
covenant  under the indenture and after that  defeasance  any omission to comply
with its  obligations and the obligations of the Guarantors with respect to such
covenant  will not  constitute  a Default  or Event of  Default.  In the event a
covenant is defeased,  certain events,  not including  non-payment,  bankruptcy,
receivership,  rehabilitation and insolvency events, described under the caption
"--Events of Default and Remedies" will no longer constitute an Event of Default
with respect to the notes.

                                       98
<PAGE>


     In order to exercise a defeasance:

     o   Concentra  Operating  must  irrevocably  deposit with the  trustee,  in
         trust,  for the  benefit  of the  holders  of the  notes,  cash in U.S.
         dollars,  non-callable  Government Securities,  or a combination of the
         two,  in such  amounts  as  will be  sufficient,  in the  opinion  of a
         nationally  recognized firm of independent public  accountants,  to pay
         the principal of, any premium and interest on the outstanding  notes on
         the stated maturity or on the applicable  redemption  date, as the case
         may be, and  Concentra  Operating  must  specify  whether the notes are
         being defeased to maturity or to a particular redemption date;

     o   in the case of any defeasance, Concentra Operating shall have delivered
         to the  trustee an opinion of counsel in the United  States  reasonably
         acceptable  to  the  trustee   confirming   that  the  holders  of  the
         outstanding notes will not recognize  income,  gain or loss for federal
         income tax purposes as a result of such  defeasance and will be subject
         to federal  income tax on the same  amounts,  in the same manner and at
         the same times as would have been the case if such  defeasance  had not
         occurred;

     o   no Default or Event of Default shall have occurred and be continuing on
         the date of such  deposit,  other  than a Default  or Event of  Default
         resulting from the borrowing of funds to be applied to such deposit;

     o   such  defeasance  will not  result  in a breach  or  violation  of,  or
         constitute a default under, any material agreement or instrument, other
         than  the  indenture,  to  which  Concentra  Operating  or  any  of its
         Subsidiaries is a party or by which  Concentra  Operating or any of its
         Subsidiaries is bound;

     o   Concentra   Operating   must   deliver  to  the  trustee  an  officers'
         certificate  stating  that  the  deposit  was  not  made  by  Concentra
         Operating  with the intent of preferring  the holders of notes over the
         other  creditors of Concentra  Operating  with the intent of defeating,
         hindering,  delaying or defrauding  creditors of Concentra Operating or
         others;

     o   no event  which  is,  or after  notice  or lapse of time or both  would
         become,  an Event of  Default  with  respect to such notes or any other
         notes shall have occurred and be continuing at the time of such deposit
         or, with regard to any such event  specified in paragraphs  (7) and (8)
         under the above caption "--Events of Default and Remedies", at any time
         on or prior to the 90th day  after the date of such  deposit,  it being
         understood  that this  condition  shall not be deemed  satisfied  until
         after such 90th day; and

     o   Concentra   Operating   must   deliver  to  the  trustee  an  officers'
         certificate and an opinion of counsel,  which opinion may be subject to
         customary assumptions and exclusions,  each stating that all conditions
         precedent relating to the defeasance have been complied with.

Amendment, Supplement and Waiver

     With the consent of the  holders of not less than a majority  in  principal
amount of the notes at the time outstanding, Concentra Operating and trustee are
permitted to amend or supplement the indenture or any supplemental  indenture or
modify the rights of the  holders;  provided  that  without  the consent of each
holder affected, no amendment, supplement, modification or waiver may:

     o   reduce the  principal  amount of notes whose holders must consent to an
         amendment, supplement or waiver;

     o   reduce the  principal  of or change the fixed  maturity  of any note or
         alter the provisions with respect to the redemption of the notes, other
         than  provisions  relating to the covenants  described  above under the
         caption "--Repurchase at the Option of Holders";

     o   reduce the rate of or change the time for  payment of  interest  on any
         note;

                                       99
<PAGE>

     o   waive a Default or Event of Default in the payment of  principal  of or
         any  premium  or  interest  on  the  notes,   except  a  rescission  of
         acceleration  of the notes by the  holders  of at least a  majority  in
         aggregate  principal  amount of the  notes and a waiver of the  payment
         default that resulted from such acceleration;

     o   make any note payable in money other than that stated in the notes;

     o   make any change in the provisions of the indenture  relating to waivers
         of past Defaults or the rights of holders of notes to receive  payments
         of principal of or any premium or interest on the notes;

     o   waive a  redemption  payment  with  respect  to any note,  other than a
         payment  required  by one of the  covenants  described  above under the
         caption "--Repurchase at the Option of Holders;"

     o   make any change in the preceding amendment and waiver provisions; or

     o   release any Guarantor from any of its  obligations  under its Guarantee
         of the notes or the indenture,  except in accordance  with the terms of
         the indenture.

     In addition, any amendment to, or waiver of the provisions of the indenture
relating to  subordination  that adversely  affects the rights of the holders of
the notes will  require the consent of the holders of at least 75% in  aggregate
principal amount of the notes then outstanding.

     Despite the above,  without  the consent of any holder of notes,  Concentra
Operating and the trustee may amend or supplement the indenture or the notes:

     o   to cure any ambiguity, defect or inconsistency;

     o   to  provide  for  uncertificated  notes in  addition  to or in place of
         certificated notes;

     o   to provide for the assumption of Concentra  Operating's  obligations to
         holders of notes in the case of a merger or  consolidation  or the sale
         of all or substantially all of Concentra Operating's assets;

     o   to make any change that would provide any additional rights or benefits
         to the  holders  of notes or that does not  adversely  affect the legal
         rights under the indenture of any such holder;

     o   to comply with  requirements  of the  Commission  in order to effect or
         maintain the  qualification  of the indenture under the Trust Indenture
         Act of 1939, as amended;

     o   to provide for the issuance of additional  notes in accordance with the
         limitations set forth in the indenture; or

     o   to allow any Subsidiary to guarantee the notes.


Concerning the Trustee

     If the trustee becomes a creditor of Concentra  Operating or any Guarantor,
the indenture  limits the trustee's right to obtain payment of claims in certain
cases, or to realize on certain  property  received in respect of any such claim
as  security or  otherwise.  The trustee  will be  permitted  to engage in other
transactions; however, if it acquires any conflicting interest it must eliminate
such conflict within 90 days, apply to the Commission for permission to continue
or resign.

     The holders of a majority in principal amount of the then outstanding notes
will have the  right to direct  the time,  method  and place of  conducting  any
proceeding  for  exercising  any remedy  available  to the  trustee,  subject to
certain  exceptions.  The  indenture  provides  that in case an Event of Default
shall occur and be continuing,  the trustee will be required, in the exercise of
its power, to use the degree of care of a prudent man in the conduct of his own



                                      100
<PAGE>

     affairs.  Subject  to  such  provisions,  the  trustee  will  be  under  no
obligation  to exercise any of its rights or powers  under the  indenture at the
request of any holder of notes,  unless  such holder  shall have  offered to the
trustee security and indemnity satisfactory to it against any loss, liability or
expense.

Book-Entry; Delivery; Form and Transfer

     The Global Note. The  certificates  representing the old notes were issued,
and the  certificates  representing  the new  notes  will be  issued,  in  fully
registered form,  without coupons.  The old notes are represented by one or more
permanent  global  certificates  in definitive,  fully  registered  form without
interest coupons in an aggregate amount of $190 million.  Except as described in
the next  paragraph,  the new notes initially will be represented by one or more
permanent global  certificates in definitive,  fully registered form and will be
deposited  with, or on behalf of, the DTC, and  registered in the name of Cede &
Co., as the DTC's nominee or will remain in the custody of the trustee  pursuant
to a FAST Balance Certificate Agreement between the DTC and the trustee. If your
interest in old notes is  represented by the initial global note and you fail to
tender  in the  exchange  offer,  we may  issue and  deliver  to you a  separate
certificate  representing  your old notes in  registered  form without  interest
coupons.

     Certain  Book-Entry  Procedures for Global Notes.  The  descriptions of the
operations and procedures of DTC that follow are provided  solely as a matter of
convenience.  These  operations  and procedures are solely within the control of
the respective settlement systems and are subject to change by them from time to
time.  Concentra  Operating  takes no  responsibility  for these  operations and
procedures and urges  investors to contact DTC or its  participants  directly to
discuss these matters.

     DTC has advised  Concentra  Operating  that: DTC is a limited purpose trust
company  organized  under  the laws of the  State of New  York,  a member of the
Federal  Reserve  System,  a  "clearing  corporation"  within the meaning of the
Uniform  Commercial  Code and a  "Clearing  Agency"  registered  pursuant to the
provisions  of the  Exchange  Act.  DTC was created to hold  securities  for its
participants   and   facilitate  the  clearance  and  settlement  of  securities
transactions  between  participants  through  electronic  book-entry  changes in
accounts of its  participants,  eliminating  the need for physical  transfer and
delivery of certificates.  Participants  include securities brokers and dealers,
banks,  trust companies and clearing  corporations and may include certain other
organizations.  Indirect access to the DTC system is available to other entities
such as banks,  brokers,  dealers  and trust  companies  that  clear  through or
maintain  a  custodial  relationship  with a  participant,  either  directly  or
indirectly.

     Under procedures established by DTC:

     (1) upon the issuance of the initial global certificate,  DTC credited,  on
         its internal system, the respective  principal amount of the individual
         beneficial  interests  represented by such global notes to the accounts
         with DTC of the participants through which such interests are held; and

     (2) ownership of beneficial  interest in the global notes are shown on, and
         the  transfer of that  ownership  is  effected  only  through,  records
         maintained  by  DTC  or its  nominees,  with  respect  to  interest  of
         participants,   and  the   records   of   participants   and   indirect
         participants,   with  respect  to  interests  of  persons   other  than
         participants.

     As long as DTC, or its nominee,  is the registered holder of a global note,
DTC or such nominee,  as the case may be, will be considered  the sole owner and
holder of the notes  represented  by such global note for all purposes under the
indenture  and the new  notes.  Except in the  limited  circumstances  described
below,  owners of beneficial  interests in a global note will not be entitled to
have any portions of such global note registered in their names, and

                                      101
<PAGE>


will not  receive  or be  entitled  to  receive  physical  delivery  of notes in
definitive  form and will not be considered  the owners or holders of the global
note, or any notes  represented  by the global note,  under the indenture or the
notes.

     The laws of some states require that certain persons take physical delivery
in  definitive  form of  securities  that  they own.  The  ability  to  transfer
beneficial  interests  in a global  note to such  persons may be limited to that
extent.  Because DTC can act only on behalf of its  participants,  which in turn
act on behalf of  indirect  participants  and  certain  banks,  the ability of a
person having  beneficial  interests in a global note to pledge such interest to
persons or entities that do not participate in the DTC system, or otherwise take
actions in respect of such interests,  may be affected by the lack of a physical
certificate evidencing such interests.

     Payments of the principal of, premium, if any, and interest on global notes
will be made to DTC or its nominee as the registered  owner of the global notes.
Neither Concentra Operating, the trustee nor any of their respective agents will
have any  responsibility  or liability for any aspect of the records relating to
or payments made on account of beneficial ownership interest in the global notes
or for  maintaining,  supervising  or  reviewing  any  records  relating to such
beneficial ownership interests.

     Concentra  Operating  expects that DTC or its nominee,  upon receipt of any
payment  of  principal   premium  or  interest  in  respect  of  a  global  note
representing  any notes held by it or its  nominee,  will  credit  participants'
accounts with payments in amounts  proportionate to their respective  beneficial
interests in the principal amount of such global note for such notes as shown on
the  records  of DTC or its  nominee.  Concentra  Operating  also  expects  that
payments by participants  to owners of beneficial  interests in such global note
held through such  participants  will be governed by standing  instructions  and
customary practices, as is now the case with securities held for the accounts of
customers  registered in "street name." Such payments will be the responsibility
of such participants.  None of Concentra Operating or the trustee will be liable
for any delay by DTC or any of its  participants  in identifying  the beneficial
owners of the notes,  and Concentra  Operating and the trustee may  conclusively
rely on and will be protected in relying on instructions from DTC or its nominee
as the registered owner of the notes for all purposes.

     Interests in the global notes will trade in DTC's Same-Day Funds Settlement
System and secondary  market  trading  activity in such interests will therefore
settle in  immediately  available  funds,  subject in all cases to the rules and
procedures of DTC and its participants.  Transfers  between  participants in DTC
will be effected in  accordance  with DTC's  procedures,  and will be settled in
same-day funds.

     DTC has advised Concentra  Operating that it will take any action permitted
to be  taken  by a  holder  of  notes  only  at the  direction  of  one or  more
participants  to whose  accounts  with DTC  interests  in the  global  notes are
credited and only in respect of such portion of the aggregate  principal  amount
of the notes as to which such participant or participants has or have given such
direction.  However,  if there  is an Event of  Default  under  the  notes,  DTC
reserves the right to exchange the global notes for notes in certificated  form,
and to distribute such notes to its participants. See "--Certificated Notes."

     Although DTC has agreed to the foregoing  procedures in order to facilitate
transfer  of   beneficial   ownership   interests  in  the  global  notes  among
participants of DTC, it is under no obligation to perform or continue to perform
such  procedures,  and such  procedures may be discontinued at any time. None of
Concentra  Operating,  the trustee nor any of their respective  agents will have

     (1) DTC:

         (a)  notifies  Concentra  Operating  that it is  unwilling or unable to
              continue  as  depositary   for  the  global  notes  and  Concentra
              Operating then fails to appoint a successor  depositary  within 90

     (3) there will have  occurred  and be  continuing  a Default or an Event of
         Default with respect to notes.

     In any such case,  Concentra  Operating  will notify the trustee in writing

in such global note,  certificated notes will be issued to each person that such
direct and indirect  participants  and the DTC identify as being the  beneficial
owner of the related notes.

     Beneficial  interests  in  global  notes  held by any  direct  or  indirect
participant  may be exchanged for  certificated  notes upon request to DTC, by a

delivered  in exchange  for any  beneficial  interest in any global note will be
registered in the names, and issued in any approved denominations,  requested by
DTC on behalf of such direct or indirect  participant,  in accordance with DTC's
customary procedures.

         will  not  be  obligations  of  the  specified  person  or  any  of its
         Restricted Subsidiaries following the Calculation Date.

     For purposes of this  definition,  whenever pro forma effect is to be given
to an Investment  or an  acquisition  or  disposition  of assets,  the amount of
income or earnings and the amount of Consolidated  Interest  Expense  associated

calculation under this definition, the pro forma calculations will be determined
in good faith by a  responsible  financial  or  accounting  officer of Concentra
Operating, including pro forma expense and cost reductions calculated on a basis
consistent  with  Regulation S-X under the Securities  Act. If any  Indebtedness
bears a floating  rate of  interest  and is being  given pro forma  effect,  the
interest  expense  on such  Indebtedness  will be  calculated  as if the rate in

                 CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

     The summary below  describes the material  United States federal income tax
consequences  of the  exchange of old notes for new notes as of the date of this
prospectus.  The  discussion  below is based upon the provisions of the Internal
Revenue  Code of  1986,  as  amended,  and  regulations,  rulings  and  judicial
decisions  thereunder  as of  the  date  hereof,  and  such  authorities  may be
repealed, revoked or modified so as to result in federal income tax consequences
different from those discussed  below.  You should consult your own tax advisors
concerning  the federal  income tax  consequences  in light of their  particular
situations  as well as any  consequences  arising  under  the laws of any  other
taxing jurisdiction.

     The  exchange  of old notes for new notes  pursuant to the  exchange  offer
should not be treated as an "exchange" for federal income tax purposes,  because
the new notes should not be  considered  to differ  materially in kind or extent
from the old notes. Rather, the new notes received by you should be treated as a
continuation of your old notes.  As a result,  there should be no federal income
tax  consequences  to you if you  exchange  notes for new notes  pursuant to the
exchange offer.

                              PLAN OF DISTRIBUTION

     Each  broker-dealer that receives new notes for its own account pursuant to
the  exchange  offer  must  acknowledge  that it will  deliver a  prospectus  in
connection  with any resale of such new  notes.  This  prospectus,  as it may be
amended or  supplemented  from time to time, may be used by a  broker-dealer  in
connection  with  resales of new notes  received in exchange for old notes where
such old notes were acquired by such  broker-dealer as a result of market-making
activities or other trading activities.  We have agreed that, for a period of 90
days  after  the  expiration  date of the  exchange  offer,  we will  make  this
prospectus  available to any  broker-dealer  for use in connection with any such
resale.  In addition,  for a period of 90 days after the  expiration  date,  all
dealers  effecting  transactions  in the new notes may be  required to deliver a
prospectus.

     We  will  not  receive  any  proceeds   from  any  sale  of  new  notes  by
broker-dealers.  New notes  received  by  broker-dealers  for their own  account
pursuant  to the  exchange  offer  may be sold  from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the  writing  of options on the new notes or a  combination  of such  methods of
resale,  at market prices prevailing at the time of resale, at prices related to
such prevailing  market prices or at negotiated  prices.  Any such resale may be
made directly to purchasers or to or through  brokers or dealers who may receive
compensation   in  the  form  of  commissions  or  concessions   from  any  such
broker-dealer  and/or the  purchasers of any such new notes.  Any  broker-dealer
that resells new notes that were received by it for its own account  pursuant to
the exchange offer and any broker or dealer that  participates in a distribution
of new notes may be deemed to be an  "underwriter"  within  the  meaning  of the
Securities  Act,  and  any  profit  on any  such  resale  of new  notes  and any
commissions  or  concessions  received  by any such  person  may be deemed to be
underwriting  compensation  under the Securities  Act. The letter of transmittal
states  that  a  broker-dealer  will  not  be  deemed  to  admit  that  it is an
"underwriter"  within the meaning of the Securities Act by acknowledging that it
will  deliver  and by  delivering  a  prospectus.  We  have  no  arrangement  or
understanding  with any broker or dealer to distribute the new notes received in
the exchange offer.

     For a period of 90 days after the  expiration  date we will  promptly  send
additional  copies of this  prospectus  and any  amendment or supplement to this
prospectus to any  broker-dealer  that requests such  documents in the letter of
transmittal.

                   Notes to Consolidated Financial Statements
                                  (Unaudited)

     The accompanying unaudited financial statements have been prepared by
Concentra Operating Corporation (the "Company" or "Concentra"), a wholly-owned
subsidiary of Concentra Managed Care, Inc. (the "Parent Company") pursuant to
the rules and regulations of the Securities and Exchange Commission, and reflect
all adjustments (all of which are of a normal recurring nature) which, in the
opinion of management, are necessary for a fair statement of the results of the
interim periods presented. These financial statements do not include all
disclosures associated with the annual financial statements and, accordingly,
should be read in conjunction with the attached Management's Discussion and
Analysis of Financial Condition and Results of Operations and the financial
statements and footnotes for the year ended December 31, 1998 included elsewhere
in this prospectus, where certain terms have been defined. See Note (2)

(1) RECAPITALIZATION TRANSACTION


     On August 17, 1999, Concentra Managed Care, Inc. (the "Parent Company")
merged (the "Merger") with Yankee Acquisition Corp. ("Yankee"), a corporation
formed by Welsh, Carson, Anderson & Stowe ("WCAS"), a 14.9% stockholder of the
company. As a result of the Merger, 41,056,966 outstanding shares of Concentra
Managed Care, Inc. common stock were converted to $16.50 per share in cash. The
remaining 6,343,203 shares held by Yankee were not converted. WCAS acquired
approximately 86%, funds managed by Ferrer Freeman Thompson & Co., LLC ("FFT")
acquired approximately 7% and other investors acquired approximately 7% of the
post-merger shares of common stock of Concentra Managed Care, Inc., Concentra
Operating Corporation's parent company, for $16.50 per share. Simultaneous with
the right to receive cash for shares, Yankee merged with and into Concentra
Managed Care, Inc., the surviving entity, and Concentra Managed Care, Inc.
contributed all of it operating assets and liabilities with the exception of
$110,000,000 of 14% Senior Discount Debentures due 2010 and $327,750,000 of 6.0%
and 4.5% Convertible Subordinated Notes to Concentra Operating Corporation (the
"Company" or "Concentra"), a wholly-owned subsidiary of Concentra Managed Care,
Inc. The net contribution by Concentra Managed Care, Inc. totaled $590,156,000.
The 6.0% and 4.5% Convertible Subordinated Notes were substantially retired
during the quarter as a result of the Merger. The Merger was accounted for as a
recapitalization transaction, with no changes to the basis of assets or
liabilities.

     The transaction was valued at approximately $1.2 billion, including the
refinancing of $327,737,000 of the 6.0% and 4.5% Convertible Subordinated Notes
that were tendered during the quarter. To finance the acquisition of Concentra
Managed Care, Inc., WCAS, FFT and other investors invested approximately
$423,679,000 in equity financing, including the value of shares already owned by
Welsh Carson, and $110,000,000 of 14% Senior Discount Debentures due 2010 with
warrants issued by Concentra Managed Care, Inc. exercisable into its common
shares. This additional debt is not guaranteed by Concentra Operating
Corporation. Concentra Operating Corporation received from various lenders
$375,000,000 in term loans, a $100,000,000 revolving credit facility to replace
the pre-merger revolving credit facility and $190,000,000 of 13% Series A Senior
Subordinated Notes due 2009. Concentra's excess cash balances funded merger and
financing related fees and expenses and related employee stock option exercises
and cancellation payments.


     Concentra incurred $18,000,000 of deferred financing fees for the issuance
of the Merger related financing, consisting primarily of underwriting fees. In
addition, Concentra recorded a non-recurring charge of $54,419,000 in the third
quarter of 1999 incurred for professional fees and services, including legal,
accounting and regulatory fees of $18,834,000, employee related stock option
exercises and cancellations of $14,598,000, a WCAS transaction fee of
$10,500,000, non-cash charges for deferred compensation expense related to the
accelerated vesting and issuance of 210,000 shares of restricted stock of
$5,493,000, and other non-recurring charges of $4,994,000. Through September 30,
1999, we paid approximately $16,385,000 for professional fees and services,
$13,502,000 for employee related stock option exercises and cancellations,
$10,500,000 for a WCAS transaction fee and $2,418,000 of other non-recurring
charges and used $5,493,000 in non-cash charges for deferred compensation
expense.  At September 30, 1999, approximately $6,121,000 of the non-recurring
charge remains for professional fees and services, employee related stock option
exercises and other non-recurring charges.

(2) BASIS OF PRESENTATION

     The accompanying consolidated financial statements as of December 31, 1998
and September 30, 1999 and for the three and nine months ended September 30,
1998 and 1999 and related footnotes reflect the operating results of Concentra
Managed Care, Inc. through August 17, 1999 and the operating results of
Concentra Operating Corporation from August 18, 1999 through September 30, 1999.
On August 17, 1999, Concentra Managed Care, Inc. ("Predecessor Concentra")
merged with Yankee and formed Concentra Managed Care, Inc. (the "Parent
Company"). The Parent Company then contributed all of its assets and shares in
its subsidiaries, including Concentra Health Services, Inc. and Concentra
Managed Care Services, Inc. to Concentra, a wholly owned subsidiary of the
Parent Company. Predecessor Concentra and Concentra are presented together since
they represent the same reporting entity. Earnings per share has not been
reported for all periods presented, as Concentra Operating Corporation is a
wholly-owned subsidiary of the Parent Company and has no publicly held shares.

     The financial statements have been restated to exclude revenue of two 50%
owned joint ventures which totaled $0, $4,561,000 and $5,724,000 for 1996, 1997
and 1998, respectively, and had no impact on net income.

     The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS 130")
effective in the second quarter of 1998. SFAS 130 establishes standards for
reporting comprehensive income and its components in the consolidated financial
statements. The Company's reported net income for the three and nine months
ended September 30, 1998 and 1999 does not differ from comprehensive income as
defined in SFAS 130.

(3) CHANGE IN ESTIMATE

     The Company has historically amortized goodwill over periods ranging from
30 to 40 years. Effective January 1, 1999, the Company changed its policy, on a
prospective basis, with respect to amortization of goodwill. All existing and
future goodwill will be amortized over a period not to exceed 25 years. Had the
Company adopted this policy at the beginning of 1998, amortization for the three
and nine months ended September 30, 1998 and for the year ended December 31,
1998 would have increased approximately $800,000, $2,400,000 and $3,300,000,
respectively. As of September 30, 1999, net intangible assets consisted of the
following:

     Goodwill, amortization period of 25 years...............    $311,707,000
     Customer lists, amortization period of 7 years .........       1,168,000
     Assembled workforce, amortization period of 5 years ....       1,330,000
                                                                  -----------
     Total intangible assets, weighted average amortization
     period of 24.8 years                                        $314,205,000
                                                                 ============

(4) RECENT ACQUISITIONS AND NON-RECURRING CHARGES


     Through September 30, 1999, the Company, through its Health Services
division had acquired 64 clinics in 21 acquisitions. The Company paid
approximately $51.0 million and recorded approximately $45,000,000 of goodwill,
$300,000 for assembled workforce and $34,000 for customer lists. No contingent
consideration exists related to these transactions.


     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 $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 (see Note 5). This transaction was accounted for as a pooling
of interests. PPS, founded in 1990, is a provider of specialized cost
containment and outsourcing services for healthcare payors.

                   Notes to Consolidated Financial Statements
                                  (Unaudited)
     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 September 30, 1999, was approximately $5,261,000 for
professional fees and services, $2,578,000 in costs associated with personnel
reductions, $1,139,000 in facility consolidations and closings, $1,627,000
associated with the write-off of deferred financing fees on PPS indebtedness
retired and $1,520,000 of other non-recurring costs. At September 30, 1999,
approximately $475,000 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, 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 September 30, 1999 was
approximately $7,416,000 in charges related to an impairment loss on the
intangible related to an acquired contract, $3,945,000 in costs associated with
personnel reductions, $351,000 in costs associated with settling claims on other
expired contracts and $2,824,000 in facility consolidations and $85,000 of other
non-recurring costs. At September 30, 1999, approximately $5,893,000 of the
non-recurring charge remains primarily related to remaining facility lease
obligations and costs associated with settling claims on certain other expired
contracts.

     In the third quarter of 1999, the Company recorded a non-recurring charge
of $54,419,000 primarily for fees, expenses and other non-recurring charges
associated with the Merger. Through September 30, 1999, we paid approximately
$16,385,000 for professional fees and services, including legal, accounting and
regulatory fees $13,502,000 for employee related stock option exercises and
cancellations, $10,500,000 for a WCAS transaction fee, and $2,418,000 of other
non-recurring charges, and used $5,493,000 in non-cash charges for deferred
compensation expense related to the accelerated vesting and issuance of 210,000
shares of restricted stock. At September 30, 1999, approximately $6,121,000 of
the non-recurring charge remains for professional fees and services, employee
related stock option exercises and other non-recurring charges.

     The following is a rollforward of the non-recurring charges recorded in
1998 and 1999:

     First quarter of 1998 $12,600,000 non-recurring charge:

                                  (Unaudited)

     On August 17, 1999, the Company entered into a $475,000,000 Credit
Agreement (the "Credit Facility") with a consortium of banks, providing for
$375,000,000 in term loans and a $100,000,000 revolving credit facility (the
"Revolving Credit Facility"). The $375,000,000 in term loans were issued as a
$250,000,000 term loan (the "Tranche B Term Loan") and a $125,000,000 term loan
(the "Tranche C Term Loan") bearing interest at the Applicable Base Rate, as
defined, plus 2.25% and 2.50%, respectively, or the Eurodollar Rate, as defined,
plus 3.25% and 3.50%, respectively. The Tranche B Term Loan matures on June 30,
2006 and requires quarterly principal payments of $625,000 through June 30, 2005
and $58,750,000 for each of the remaining four quarters. The Tranche C Term Loan
matures on June 30, 2007 and requires quarterly principal payments of $312,500
through June 30, 2006 and $29,062,500 for each of the remaining four quarters.
The $100,000,000 Revolving Credit Facility matures on August 17, 2005.
Borrowings under the Revolving credit facility are payable, at the Company's
option at ABR plus 1.75% or the Eurodollar Rate plus 2.75%. Commitment fees on
the unused revolver borrowings are at 0.5% per annum. The Company had borrowings
outstanding under the Revolving Credit Facility of $1,500,000 at September 30,
1999.


     The  $190,000,000  13%  Series  A  Senior   Subordinated  Notes  (the  "13%
Subordinated Notes") due August 15, 2009 are general unsecured indebtedness with
semi-annual  interest  payments due on February 15 and August 15  commencing  on
February 15, 2000. The Company can redeem the 13% Subordinated Notes on or after
August 15, 2004 at 106.5% of the principal  amount with the  redemption  premium
decreasing  annually to 100.0% of the principal  amount on August 15, 2008.  The
13% Subordinated Notes are guaranteed by each and every wholly owned subsidiary,
the results of which are all  consolidated  in the results of the  Company,  the
guarantees  are  full  and  unconditional,  and the  Company  has no  assets  or
operations  separate from the  investments in these  subsidiaries.  As a result,
separate financial statements of the Company's subsidiaries are not provided.


     The Credit Facility and 13% Subordinated Notes contain certain 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 Credit Facility, the Company is
also required to satisfy certain financial covenant ratio tests including
leverage ratios, interest coverage ratios and 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.

     The Company was in compliance with its covenants, including its financial
covenant ratio tests, in the third quarter of 1999.

     In December 1996, the Company issued $97,750,000 of 6.0% Convertible
Subordinated Notes due 2001. On September 17, 1997, the Company entered into a
$100,000,000 Senior Credit Facility with a syndicate of five banks. 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 debt associated with its
acquisition of PPS. On February 24, 1998, the Company acquired PPS and retired
$49,000,000 of PPS' outstanding indebtedness. PPS' 5.0% Convertible Subordinated
Notes due August 2006 converted into 2,721,904 shares of Concentra Managed Care,
Inc. common stock. In March and April 1998, the Company issued $230,000,000 4.5%
Convertible Subordinated Notes due 2003 and the Senior Credit Facility borrowing
capacity was reduced to the original $100,000,000 amount. On August 17, 1999,
the Senior Credit Facility was replaced with the Revolving Credit Facility and
substantially all of the 6.0% and 4.5% Convertible Subordinated Notes were
retired through debt tender offers during the quarter in connection with the
Merger.

(6) 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:

                                      F-9
<PAGE>
                         CONCENTRA OPERATING CORPORATION

                   Notes to Consolidated Financial Statements
                                  (Unaudited)

     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, specialized preferred provider
organization ("PPO") network access, independent medical examinations ("IMEs"),
peer reviews and out-of-network bill review services. These services are
designed to reduce the cost of workers' compensation claims, automobile accident
injury claims and group health claims.

     Field Case Management provides services involving case managers and nurses
working on a one-on-one basis with injured employees and their various
healthcare 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 Field Case Management and Cost Containment 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 Group 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 41.6% and 42.5% of total Managed Care Services revenue for the three
and nine months ended September 30, 1999, respectively.

     There has not been a material change in the composition of segment
identifiable assets as of September 30, 1999 as compared to December 31, 1998
amounts reported in the Company's financial statements for the year ended
December 31, 1998 included elsewhere in this prospectus. Revenues from
individual customers, revenues between business segments and revenues, operating
profit and identifiable assets of foreign operations are not significant.

(1) Prior to 1999, corporate-level general and administrative expenses were
    reported in the Health Services and Managed Care Services groups based on
    where general and administrative activities were budgeted. In addition,
    general and administrative expenses for the Managed Care Groups was not
    separately reported prior to 1999. Therefore, the Company did not make
    allocations of corporate level and managed care level general and
    administrative expenses. Beginning in 1999, the corporate function has been
    separately disclosed.

(2) The third quarter of 1999 non-recurring charge of $54,419,000 for Merger
    related fees and expenses consists of professional fees and services,
    including legal, accounting and regulatory fees of $18,834,000 employee
    related stock option exercises and cancellations of $14,598,000 a WCAS
    transaction fee of $10,500,000, non-cash charges for deferred compensation
    expense related to accelerated vesting and issuance of 210,000 shares of
    restricted stock of $5,493,000, and other non-recurring charges of
    $4,994,000.

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

                          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
nonrecurring 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").

                                      F-18

<PAGE>
     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.

     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. None of
these acquisitions were significant in relation to the Company's consolidated
financial statements and, therefore pro forma financial information has not been
presented. 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.

     Effective January 1, 1999, the Company changed its policy, on a prospective
basis, with respect to the amortization of goodwill. All existing and future
goodwill will be amortized over a period not to exceed 25 years.

(3) Summary of Significant Accounting Policies

(a) Consolidation

     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. Investments in certain joint ventures with
less than a 51% ownership interest are accounted for on a equity basis and,
accordingly, consolidated income includes the Company's share of their income.
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. Health Services has a nominee shareholder relationship with
the Physician Groups as defined in EITF 97-2, Application of APB Opinion No. 16
and FASB Statement No. 94 to Physician Practice Entities, and as a result, the
financial statements of the Physician Groups are consolidated. Specifically:

     o   Health Services can at all times establish or effect change in the
         nominee shareholder;

     o   Health Services can cause a change in the nominee shareholder an
         unlimited number of times;


                                      F-19
<PAGE>
     o   Health Services has sole discretion as to the choice of a new nominee
         shareholder;

     o   Health Services has sole discretion without cause to establish or
         change the nominee shareholders;

     o   Health Services and the Physician Groups would incur no more than a
         nominal cost to cause a change in the nominee shareholder; and,

     o   Neither Health Services nor the Physician Groups are subject to any
         significant adverse impact upon a change in the nominee shareholder.

     The Company's management fees from the Physician Groups are calculated as
collected revenue net of compensation, benefits and other expenses incurred by
the Physician Groups.

(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.

(c) Revenue Recognition


     The Company recognizes revenue primarily as services have been rendered
based on time and expenses incurred or as task based projects are completed and
customers are obligated to pay. 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.


     The Company's Health Services division's 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. The workers' compensation injury care and related services'
provider reimbursement methods vary on a state-by-state basis. Of the 25 states
in which the Company currently operates occupational healthcare centers, 21 have
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 the four
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. Billing for services in states with fee
schedules are included in revenues net of allowance for estimated differences
between list prices and allowable fee schedule rates. Adjustments to the
allowance based on final payment from the states are recorded upon settlement.
The Company records the net revenue amount as accounts receivable.

     The Company's total contractual allowances offset against revenues during
the years ended December 31, 1998, 1997 and 1996 were $16,095,000, $14,718,000
and $3,680,000, respectively.

     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

                                      F-20

<PAGE>

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:

Asset Classification                     Estimated Useful Life
- --------------------                     ---------------------
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


(e) Intangible Assets

     The value of goodwill, assembled workforces and customer lists are recorded
at cost at the date of acquisition. Through December 31, 1998 goodwill,
including any excess arising from earn-out payments, was 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". Effective
January 1, 1999, the Company changed its policy, on a prospective basis, with
respect to the amortization of goodwill. All existing and future goodwill will
be amortized over a period not to exceed 25 years, Had the Company adopted this
policy at the beginning of 1998, amortization for 1998 would have increased by
approximately $3,300,000 and diluted earnings per share would have been $0.42.
As of December 31, 1998, net intangible assets consisted of goodwill, customer
lists and assembled workforce. The Company believes that the life of the core
businesses acquired and the delivery of occupational healthcare services is
indeterminate and likely to exceed 25 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 has recorded
accumulated amortization on intangible assets of $29,834,000 and $37,938,000
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 operating
unit's undiscounted cash flows over the remaining life of the goodwill and
compares it to the operating unit's goodwill balance to determine whether the
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.

     Effective January 1, 1999, the Company changed its policy, on a prospective
basis, with respect to the amortization of goodwill. All existing and future
goodwill will be amortized over a period not to exceed 25 years.

(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.

(h) Investments in Joint Ventures

     Investments in the net assets of joint ventures accounted for under the
equity method amounted to $3,937,000 and $3,839,000 at December 31, 1997 and
1998, respectively. For the year ending December 31, 1997 and 1998, revenue for
these entities was $4,561,000 and $5,724,000, gross profit was $950,000 and
$919,000 and net income was $287,000 and $338,000, respectively. Total assets
for the joint ventures were $4,277,000 and $4,306,000 as of December 31, 1997
and 1998, respectively.

(i) Self Insurance

     Company is partially insured for workers' compensation, physician medical
malpractice, automobile and certain employee health benefits. The Company's
self-insurance retention liability on a per claim basis ranges from $100,000 to
$250,000. Liabilities in excess of these amounts are the responsibility of the
insurer. The Company's policy is to accrue amounts up to the insurance carriers'
reserve requirements on a claim-by-claim basis and an estimate for claims
incurred but not yet reported.

(j) 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

                                      F-22

<PAGE>

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.

(k) 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.

(l) 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.

(m) 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.

(n) 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) Earnings Per Share

     As a result of the Company going private in the merger transaction on
August 17, 1999, there are no longer publicly held shares outstanding.
Therefore, historical earnings per share information is not meaningful.

(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-23
<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.

</TABLE>

     As of December 31, 1998 and 1997, accrued interest was $3,276,000 and $
867,000 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 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, 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 pre-

                                      F-27
<PAGE>


mium 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.

(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-cancellable
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 schedule of rent expense by major category for the years

     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.

(c) 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.


                                      F-29
<PAGE>

     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.

     The Company issued the following shares of Common Stock under the employee
stock purchase plans for each of the following purchase periods:

                                                       Weighted
                                                       Average
                                                        Price
Purchase Periods Ended                 of Shares      Per Share
                                       ---------      ---------
December 31, 1995 ...................    32,682         $10.49
June 30, 1996 .......................    29,089         $10.59
December 31, 1996 ...................    44,606         $22.18
June 30, 1997 .......................    50,056         $21.38
December 31, 1997 ...................    47,245         $24.86
June 30, 1998 .......................    64,587         $22.10
December 31, 1998 ...................   160,512         $ 9.08



(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.

                                      F-30
<PAGE>

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

date of grant. After the merger, no additional awards were made under 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.

(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 and pro forma net income would have been
reduced to the following supplemental pro forma amounts:

<TABLE>

                                                      1996              1997             1998

  Supplemental pro forma (1)..............        $19,825,000           $801,000
</TABLE>

(1)  Pro forma net income 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.

     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.

     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.

                                      F-32
<PAGE>

     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 Group 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:

     where general and administrative activities were budgeted. In addition,
     general and administrative expenses for the Managed Care Groups was not
     separately reported prior to 1999. Therefore, the Company did not make
     allocations of corporate level and managed care level general and
     administrative expenses. Beginning in 1999, the corporate function will be

(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 14.9% 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, WCAS
will acquire approximately 87%, funds managed by Ferrer Freeman Thompson & Co.
("FFT") will acquire approximately 7% and other investors will acquire
approximately 6% 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 in the third 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
$369,432,000 in equity financing, including the value of shares and convertible
notes already owned by WCAS, and up to $110,000,000 in subordinated
indebtedness. Additionally, FFT will invest approximately $30,600,000 and other
investors will invest approximately $23,000,000 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, Concentra would also utilize excess cash on hand at the time of
the merger to help finance the purchase of the Concentra Common Stock.
Simultaneous with the right to receive cash for shares, Yankee would merge with
Concentra with Concentra 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


                                      F-34

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.

(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 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)  The ratio of earnings to fixed charges is computed by dividing the sum of
     net earnings, before deducting provisions for income taxes and fixed
     charges less equity in earnings of unconsolidated subsidiaries, net of
     related distributions, by fixed charges. Fixed charges consist of interest
     on debt, including amortization of debt issuance costs, and one-fourth of
     rent expenses, estimated by management to be the interest component of such
     rentals. The ratio of earnings to fixed charges is not adequate to cover
     fixed charges for the pro forma year ended December 31, 1998 and the pro
     forma nine month period ended September 30, 1999, by $5,207,000, and
     $43,211,000, respectively.
