                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Unaudited)



     The accompanying unaudited consolidated financial statements have been
prepared by Concentra Operating Corporation (the  "Company" or "Concentra
Operating") pursuant to the rules and regulations of the Securities and Exchange
Commission ("SEC"), and contain all adjustments, consisting only of normal,
recurring adjustments, which in the opinion of management, are necessary for a
fair statement of the results for the interim periods presented.  Results for
interim periods should not be considered indicative of results for a full year.
These consolidated financial statements do not include all disclosures
associated with the annual consolidated 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 consolidated
financial statements and footnotes for the year ended December 31, 1999,
included in the Company's 1999 Form 10-K, where certain terms have been defined.
Earnings per share has not been reported for all periods presented, as Concentra
Operating is a wholly-owned subsidiary of Concentra Managed Care, Inc. ("CMC")
and has no publicly held shares.

(1)  Recapitalization Transaction

     On August 17, 1999, CMC merged (the "1999 Merger") with Yankee Acquisition
Corp. ("Yankee").  All CMC shares not held by Yankee were then converted to
cash, and the remaining post-merger shares were acquired by certain investors.
Simultaneous with the right to receive cash for shares, Yankee merged with and
into CMC, the surviving entity, and CMC contributed all of its operating assets,
liabilities, and shares in its subsidiaries, including Concentra Health
Services, Inc. ("Health Services"), Concentra Managed Care Services, Inc., and
Concentra Preferred Systems, Inc., with the exception of $110 million Senior
Discount Debentures and $327.7 million of Convertible Subordinated Notes, to
Concentra Operating in exchange for 1,000 shares of Concentra Operating common
stock.  The 1999 Merger was accounted for as a recapitalization transaction,
with no changes to the basis of assets or liabilities.

(2)  Basis of Presentation

     The accompanying consolidated financial statements as of June 30, 2000, and
December 31, 1999, and for three and six months ended June 30, 2000, and June
30, 1999, and related footnotes reflect the operating results of CMC through
August 17, 1999, and of Concentra Operating thereafter.  CMC and Concentra
Operating are presented together through August 17, 1999, since they represent
the same reporting entity for the periods presented.

(3)  Recent Accounting Pronouncement

     In December 1999, the SEC issued Staff Accounting Bulletin No. 101 ("SAB
101"), "Revenue Recognition in Financial Statements."   SAB 101 is effective for
the first quarter of 2000 and provides additional guidance in applying generally
accepted accounting principles for revenue recognition in financial statements
based on interpretations and practices followed by the SEC.  The Company has
evaluated its revenue recognition practices and has determined that the bulletin
will not have a material impact on the Company's consolidated financial
statements.

                                    ========                 ========
</TABLE>


     The Company's revolving credit borrowings at June 30, 2000, and December
31, 1999, were $10.0 million and $4.0 million, respectively. As of June 30,
2000, and December 31, 1999, accrued interest was $14.7 million and $12.4
million, respectively.

     On March 21, 2000, Concentra and its lenders amended its $475 million
senior secured credit agreement (the "Credit Facility.") Under the terms of the
amended agreement, the financial compliance ratios have been modified to allow
for increased leverage through September 2003 and decreased interest coverage
through September 2004, as compared to the original agreement. In order to
receive these amended ratios, the amended agreement provides for an interest
rate increase of 0.75% on outstanding borrowings under the Credit Facility. As a
part of the amendment, the Company was also required to pay a fee of $1.7
million to lenders approving the amendment. The amendment fee was capitalized as
deferred financing costs and will be amortized over the remaining life of the
Credit Facility. A failure to comply with these and other financial compliance
ratios could cause an event of default under the Credit Facility which could
result in an acceleration of the related indebtedness before the terms of that
indebtedness otherwise require the Company to pay that indebtedness. Such an
acceleration would also constitute an event of default under the indentures
relating to the $190 million 13% Senior Subordinated Notes (the "13%
Subordinated Notes") and could also result in an acceleration of the 13%
Subordinated Notes before the indentures otherwise require the Company to pay
the notes.

     The Credit Facility requires the Company to enter into interest rate swap
agreements for the purpose of reducing the effect of interest rate fluctuations
on a certain portion of the Credit Facility.  On May 17, 2000, the Company
amended its interest rate swap agreement that converts $200 million of certain
variable rate debt to fixed rates.  This agreement expires November 17, 2004.
Under the new agreement, the Company generally pays and receives the three month
LIBOR rate (the "Swap Rate") to and from the counterparty on the notional amount
subject to the following limitations: the minimum rate the Company pays is 6.3%
when the Swap Rate is less than 5.9%; the maximum rate the Company pays is 6.3%,
unless the Swap Rate is greater than 7.5% and less than 8.5%; and, if the Swap
Rate is greater than 8.5%, the Company pays 8.5% until November 17, 2002.  After
November 17, 2002 through the maturity of the agreement, there is no maximum
rate the Company pays if the Swap Rate exceeds 7.5%.

     The Company entered into an additional interest rate swap agreement on May
17, 2000. This agreement converts $100 million of certain variable rate debt to
fixed rates and expires on May 17, 2005. Under the terms of this agreement, the
Company generally pays and receives the Swap Rate to and from the counterparty
on the notional amount subject to the following restrictions: the minimum rate
the Company pays is 7.05% when the Swap Rate is less than 6.0%; the maximum rate
the Company pays is 7.05%, unless the Swap Rate is greater than 8.25%. Through
the maturity of the agreement, there is no maximum rate the Company pays if the
Swap Rate exceeds 8.25%. The impact of these interest rate swap transactions on
our financial position and results of operations is not material.

     The Credit Facility and the 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 was in compliance with its covenants,
including its financial covenant ratio tests, for the second quarter of 2000.
The Company's obligations under the Credit Facility are secured by a pledge of
stock in the Company's subsidiaries and a pledge of the Company's and its
subsidiaries' assets.

     The fair value of the Company's borrowings under the Credit Facility was
$350.8 million, as of June 30, 2000.  The fair value of the Company's 13%
Subordinated Notes was $161.5 million at June 30, 2000.  The fair values of the
financial instruments were determined utilizing available market information.
The use of different market assumptions or estimation methodologies could have a
material effect on the estimated fair value amounts.

(5)  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 is a brief description of these reportable segments:

     Health Services provides specialized injury and occupational healthcare
services to employers through its network of health centers.  Health Services
delivers primary and rehabilitative care, including the diagnosis, treatment and
management of work-related injuries and illnesses.  Health Services also
provides a full complement of non-injury, employment-related health services,
including physical examinations, pre-placement substance abuse testing, job-
specific return to work evaluations and other related programs.

     Specialized Cost Containment services include first report of injury,
utilization management (pre-certification and concurrent review), retrospective
medical bill review, telephonic case management, specialized preferred provider
organization network access, independent medical examinations, 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.

     There has not been a material change in the composition of segment
identifiable assets as of June 30, 2000, as compared to the December 31, 1999
amounts reported in the Company's 1999 Form 10-K.  Revenue from individual
customers, revenue between business segments and revenue, operating profit and
identifiable assets of foreign operations are not significant.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

     This section contains certain forward-looking statements that are based on
management's current views and assumptions regarding future events, future
business conditions and the outlook for the Company based on currently available
information.  Wherever possible, the Company has identified these "forward-
looking statements" (as defined in Section 27A of the Securities Act and Section
21E of the Exchange Act) by words and phrases such as "anticipates", "plans,"
"believes," "estimates," "expects," "will be developed and implemented," and
similar expressions.  Readers are cautioned not to place undue reliance on these
forward-looking statements.  These forward-looking statements are subject to
risks and uncertainties, and future events could cause the Company's actual
results, performance, or achievements to differ materially from those expressed
in, or implied by, these statements. These risks and uncertainties include, but
are not limited to, general industry and economic conditions; shifts in customer
demands; the ability to manage business growth and diversification; the ability
to identify suitable acquisition candidates or joint venture relationships for
expansion and consummating such matters on favorable terms; the ability to
attract and retain qualified professionals and other employees to expand and
complement the Company's services; the effectiveness of the Company's
information systems and controls; the ability to meet the Company's debt,
interest and operating lease payment obligations; possible litigation and legal
liability in the course of operations; fluctuations in interest and tax rates;
strategies pursued by competitors; restrictions imposed by government
regulation; and changes in the industry resulting from changes in workers'
compensation laws, regulations and in the healthcare environment generally.
Further, forward-looking statements are made in the context of information
available as of the date stated, and the Company assumes no obligation to update
or revise publicly any forward-looking statements, whether as a result of new
information, future events, or otherwise.

     Reference is hereby made to the Company's Form 10-K for the year ended
December 31, 1999, filed with the Securities and Exchange Commission, where
certain terms have been defined and for certain considerations that could cause
actual results to differ materially from those contained in this document.

     Recapitalization Transaction

     On August 17, 1999, Concentra Managed Care, Inc. ("CMC") merged (the "1999
Merger") with Yankee Acquisition Corp. ("Yankee").  All CMC shares not held by
Yankee were then converted to cash, and the remaining post-merger shares were
acquired by certain investors.  Simultaneous with the right to receive cash for
shares, Yankee merged with and into CMC, the surviving entity, and CMC
contributed all of its operating assets, liabilities, and shares in its
subsidiaries, including Concentra Health Services, Inc., Concentra Managed Care
Services, Inc., and Concentra Preferred Systems, Inc., with the exception of
$110 million Senior Discount Debentures and $327.7 million of Convertible
Subordinated Notes, to Concentra Operating Corporation ("Concentra Operating" or
the "Company") in exchange for 1,000 shares of Concentra Operating common stock.
The 1999 Merger was accounted for as a recapitalization transaction, with no
changes to the basis of assets or liabilities.

     Overview

     The following represents a discussion and analysis of the operations of CMC
through August 17, 1999, and of Concentra Operating thereafter. CMC and
Concentra Operating are presented together through August 17, 1999, since they
represent the same reporting entity for the periods presented.

     Health Services provides specialized injury and occupational healthcare
services to employers through our network of health centers.  Health Services
delivers primary and rehabilitative care, including the diagnosis, treatment and
management of work-related injuries and illnesses.  Health Services also
provides a full complement of non-injury, employment-related health services,
including physical examinations, pre-placement substance abuse testing, job-
specific return to work evaluations and other related programs.  For the six
months ended June 30, 2000 and 1999, Health Services derived 63.7% and 63.1% of
its net revenue from the treatment of work-related injuries and illnesses,
respectively and 36.3% and 36.9% of its net revenue from non-injury related
medical services, respectively.

Results of Operations for the Three and Six Months Ended June 30, 2000 and 1999

Revenue

     Total revenue increased 9.3% in the second quarter of 2000 to $190.3
million from $174.1 million in the second quarter of 1999. Health Services'
revenue increased 25.7% in the second quarter of 2000 to $103.0 million from
$81.9 million in the second quarter of 1999. Specialized Cost Containment's
revenue decreased 5.0% in the second quarter of 2000 to $51.5 million from $54.2
million in the second quarter of 1999. Field Case Management's revenue decreased
5.5% in the second quarter of 2000 to $35.8 million from $37.9 million in the
second quarter of 1999.

     Total revenue for the six months ended June 30, 2000 increased 12.7% to
$371.4 million from $329.5 for the six months ended June 30, 1999. Health
Services' revenue increased 29.3% for the six months ended June 30, 2000 to
$197.3 million from $152.6 million for the same period in the prior year. For
the first six months of 2000, Specialized Cost Containment's revenue increased
2.2% to $103.2 million from $100.9 million. Field Case Management's revenue
decreased 6.6% to $71.0 million for the first half of 2000 from $76.0 million
for the first six months of 1999.

     Health Services' revenue growth resulted primarily from the acquisition of
new centers and an increase in patient visits within existing markets. The
number of visits to Health Services' centers in the second quarter of 2000
increased 25.4% in total compared with the second quarter of 1999 and 11.9% on a
same-market basis. For the six months ended June 30, 2000, visits increased
24.9% in total and 10.2% on a same market basis as compared to the same period
in the prior year. Average revenue per visit declined slightly by 1.2% during
the quarter and remained consistent for the first half of 2000 as compared to
the same respective periods in 1999. The second quarter decrease in average
revenue per visit was due primarily to an increase in the number of non-injury
related visits relative to injury-related visits. The average fees charged for
non-injury visits are generally lower than those charged for injury-related
visits. For the second quarter and for the first six months of 2000, Health
Services' non-injury related visits constituted approximately 52% of its total
visits as compared to approximately 50% in the prior year. We currently
anticipate that this trend of higher visit growth from non-injury visits
relative to visit growth of injury-related visits will continue and that we will
experience an increasing percentage of non-injury visits as compared to total
visits in future periods.

     The decrease of Specialized Cost Containment revenue for the second quarter
of 2000 is primarily related to a year-over-year decrease in revenue from our
out-of-network bill review business, Concentra Preferred Systems. This decrease
was in large part due to the strong billings by Concentra Preferred Systems in
the second quarter of 1999 for contract compliance related review services that
were not replicated in the current year. To a lesser extent, Concentra Preferred
Systems' growth during the second quarter was adversely affected by a decline in
the average size of invoices reviewed which offset increases in bill volume over
the prior year. We currently anticipate that, due to a maturation of its
traditional service offerings and possible market trends, this business may
continue to experience decreasing bill sizes in future periods as it increases
its bill volumes, and may experience a corresponding reduction in revenue growth
from traditional out-of-network bill review services. To offset this potential
slowing of revenue growth, management is currently pursuing sales of newer
service offerings, including a "quilted" preferred provider organization
offering, contract compliance services and other post-payment review services.
Decreases in year over year revenue growth from our out-of-network bill review
services during the second quarter were partially mitigated by increasing
revenue from our first report of injury services and claims review services. For
the six months ended June 30, 2000, the second quarter decrease in out-of-
network bill review services was more than offset by growth in first report of
injury services, preferred provider organization network access fees, claims
review services and first quarter growth in out-of-network bill review services
as compared to the same period in 1999.

     Although revenue has grown modestly during the past two sequential
quarters, we continue to report year over year declines in revenue from our
Field Case Management business as compared to the same periods in 1999. Revenue
declines have been primarily due to decreases in business volume resulting
mainly from customer uncertainty from our 1998 fourth quarter reorganization of
this line of business, our competitors' related marketing efforts and, to a
lesser extent, the recent "task-based" approach to service delivery. These
trends have lessened during the first and second quarters of 2000. Continued
improvement in revenue trends, however, will be subject to a number of factors,
including the success of our current marketing and management initiatives.

the first six months of 1999.  Health Services' gross profit margin decreased to
22.2% and 20.4% for the three and six months ended June 30, 2000, respectively,
from 23.6% and 21.1% in the same respective periods in the prior year.  In 1999,
Health Services acquired 53 centers in 20 transactions.  For the second quarter
of 2000, Health Services acquired three centers in two transactions, for a total
of eight centers in five transactions for the first six months of 2000.
Historically, consolidated gross profit margins are initially negatively
impacted due to lower margins from centers recently acquired.  However, as we
have consolidated certain functions, made other staff-related changes and
increased patient volume, the margins of our acquired centers have demonstrated
improvements.

     Specialized Cost Containment's gross profit margin declined to 31.2% and
31.3% in the first three and six months of 2000 from 36.0% and 33.0% in the
first three and six months of 1999, respectively. These decreases relate
primarily to the strength of the prior year's out-of-network bill review gross
profit and the continued revenue decline in our traditional bill review product
offerings. The lower margins were partially offset by improved profit margins in
claims review and first report of injury services when compared to the same
periods in the prior year.

     The gross profit margin for Field Case Management decreased to 11.7% and
10.5% for the three and six months ended June 30, 2000, respectively, from 13.2%
for the same periods in 1999. This decrease in profit margin is primarily due to
lower revenue as compared to the same periods last year, offset partially by
lower expenses. We currently expect the recent margin decreases to continue to
stabilize. This stabilization, however, will be dependent on several factors,
including the success of our marketing and management efforts.

General and Administrative Expenses

     General and administrative expenses decreased 3.5% in the second quarter of
2000 to $16.2 million from $16.8 million in the second quarter of 1999, or 8.5%
and 9.7%, respectively, as a percentage of revenue for the second quarters of
2000 and 1999.  This decrease primarily relates to Y2K expenditures made in the
second quarter of 1999 that were not incurred in 2000, as well as the
realization of certain cost reduction initiatives.  For the six months ended
June 30, 2000, general and administrative expenses increased 6.1% to $33.2
million, or 8.9% of revenue, from $31.3 million, or 9.5% of revenue, in the
first half of 1999.  This increase was primarily due to our continued investment
in support personnel and information technology in the first quarter of 2000.

Amortization of Intangibles

     Amortization of intangibles increased 17.4% for the first three and six
months of 2000 to $3.7 million and $7.2 million, respectively, from $3.1 million
and $6.2 million for the same respective periods in 1999. The increase is the
result of the amortization of additional intangible assets such as goodwill,
customer lists and assembled workforces, primarily associated with acquisitions
by Health Services.

Interest Expense

     Interest expense increased $13.2 million in the second quarter of 2000 to
$17.9 million from $4.7 million in the second quarter of 1999 and increased
$24.8 million in the first half of 2000 to $34.1 million from $9.4 million in
the first half of 1999.  These increases are due primarily to increased
outstanding borrowings from the issuance of $565.0 million in merger-related
financing incurred in the third quarter of 1999, partially offset by the
retirement of substantially all of the $327.7 million of existing convertible
subordinated notes during the 1999 Merger.  We expect interest expense for 2000
to be approximately $72.2 million compared to 1999 interest expense of $35.8
million.  This anticipated increase is primarily a result of a full year of
increased borrowing and, to a lesser extent, additional interest related to the
amendment of our credit facility in the first quarter of 2000.  As of June 30,
2000, approximately 67% of our debt contains floating rates. Although we utilize
interest rate swaps to manage a portion of this market exposure, rising interest
rates would negatively impact our results of operations.  See "Item 3.
Quantitative and Qualitative Disclosures About Market Risk."

Interest Income

     Interest income decreased $0.7 million in the second quarter of 2000 to
$0.3 million from $1.0 million in the second quarter of 1999. For the first half
of 2000, interest income declined by $1.7 million to $0.4 million from $2.1
million in the first half of 1999. These decreases are primarily due to excess
cash being used to complete the 1999 Merger transaction and to pay related fees
and expenses.

Provision for Income Taxes

     We recorded a tax provision of $3.2 million and $3.3 million in the first
three and six months of 2000, which reflects effective tax rates of 56.8% and
56.0%, respectively.   For the first three and six months of 1999, we recorded a
tax provision of $8.5 million and $13.0 million, respectively, reflecting an
effective tax rate of 42.5%.  The increase in our effective rate is primarily
due to permanent differences related to nondeductible goodwill.

Liquidity and Capital Resources

     For the six months ended June 30, 2000, cash provided by operating
activities was $9.0 million as compared to $15.9 million provided from operating
activities in the first half of 1999. During the first six months of 2000, $13.5
million of cash was used for working capital purposes, primarily related to an
increase in accounts receivable of $7.2 million and a decrease in accounts
payable and accrued expenses of $6.4 million. Accounts receivable increased
primarily due to continued revenue growth, while accounts payable and accrued
expenses decreased primarily due to the timing of certain payments, including
payment of accrued interest on the Company's 13% Senior Subordinated Notes and
payroll-related items.

     For the six months ended June 30, 2000, we used net cash of $8.3 million in
connection with acquisitions and $14.8 million of cash to purchase property and
equipment during the first half of 2000, primarily consisting of new computer
hardware and software technology as well as leasehold improvements.

     Cash flow provided by financing activities of $2.4 million was due
primarily from $6.0 million in additional borrowings under our revolving credit
facilities, partially offset by $2.0 million in debt repayments and the payment
of $1.7 million of deferred financing costs related to the renegotiation of the
financial covenant ratio tests associated with our credit facility.

     We were in compliance with our covenants, including our financial covenant
ratio tests, in the second quarter of 2000.  At June 30, 2000, we had borrowings
outstanding under our revolving credit facility of $10.0 million.

                                       14
<PAGE>

     During the first half of 2000, we made approximately $1.7 million in cash
payments related to the non-recurring charges that occurred in the first quarter
of 1998, fourth quarter of 1998 and third quarter of 1999.  Within the next
twelve months, it is anticipated that approximately $3.5 million in cash
payments will be made related to these non-recurring charges.  These
expenditures are anticipated to consist of  $1.0 million of fees and other
expenses related to the 1999 Merger, $0.4 million of employee-related costs,
$0.5 million of facility-related costs, $1.5 million of costs associated with
settling claims on certain expired contracts and $0.1 million of other costs.

     We currently 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 the foreseeable future.
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 certain that any future debt or equity financing will be
available on terms favorable to us, or that our long-term cash generated from
operations will be sufficient to meet our long-term obligations.


Item 3.  Quantitative and Qualitative Disclosures About Market Risk

     We have fixed rate and variable rate debt instruments. Our variable rate
debt instruments are subject to market risk from changes in interest rates. In
order to manage this risk under the Credit Facility, we have entered into an
interest rate hedge. We do not hold or issue derivative financial instruments
for trading purposes and are not a party to any leveraged derivative
transactions. Sensitivity analysis is one technique used to measure the impact
of changes in the interest rates on the value of market-risk sensitive financial
instruments. A hypothetical 10% movement in interest rates would not have a
material impact on our future earnings, fair value or cash flows. For more
information on the interest rate hedge, see "Note 4 to the Consolidated
Financial Statements" and Note 5 in the audited consolidated financial
statements of the Company's 1999 Form 10-K.
