                  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 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.  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, 2000, included in the Company's
2000 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 Inc. ("Concentra Holding") and has no publicly
held shares.

(1)  Recent Accounting Pronouncement

     In July 2001, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. ("FAS") 141, "Business
Combinations" ("FAS 141") and FAS 142, "Goodwill and Other Intangible Assets"
("FAS 142"). FAS 141 addresses the initial recognition and measurement of
goodwill and other intangible assets acquired in a business combination. FAS 142
addresses the initial recognition and measurement of intangible assets acquired
outside of a business combination, whether acquired individually or with a group
of other assets, and the accounting and reporting for goodwill and other
intangibles subsequent to their acquisition. These standards require all future
business combinations to be accounted for using the purchase method of
accounting. Goodwill will no longer be amortized but instead will be subject to
impairment tests at least annually. The Company is required to adopt FAS 141 and
FAS 142 on a prospective basis as of January 1, 2002; however, certain
provisions of these new standards may also apply to any acquisitions concluded
subsequent to June 30, 2001. As a result of implementing these new standards,
the Company will discontinue the amortization of goodwill as of December 31,
2001.

     Management believes the adoption of FAS 142 will have a material impact on
its financial statements in that its income will be increased by an amount equal
to the amortization expenses that would have otherwise been charged to earnings
under current accounting standards, approximately $14.5 million annually.
Additionally, the Company's future earnings may periodically be affected in a
materially adverse manner should particular segments of its goodwill balances
become impaired pursuant to the valuation methodology.

(2)  Revolving Credit Facility and Long-Term Debt
     The Company's long-term debt as of June 30, 2001, and December 31, 2000,
consisted of the following (in thousands):

     The Company had no borrowings under its available $100 million revolving
line of credit at June 30, 2001, or December 31, 2000. As of June 30, 2001, and
December 31, 2000, accrued interest was $13.9 million and $11.6 million,
respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, Continued
                                  (Unaudited)

     The $475 million senior secured credit agreement ("Credit Facility") and
the $190 million 13% Senior Subordinated Notes ("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 2001.
These ratio tests become more restrictive for future periods. The Company's
ability to be in compliance with these more restrictive ratios will be dependent
on its ability to increase its cash flows over current levels. 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
$364.8 million and $333.3 million, as of June 30, 2001 and December 31, 2000,
respectively. The fair value of the Company's 13% Subordinated Notes was $203.3
million and $168.2 million at June 30, 2001 and December 31, 2000, respectively.
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.

(3)  Non-Recurring Charge

     During the six months ended June 30, 2001, we made approximately $0.4
million in cash payments related to the non-recurring charges that occurred in
the second quarter of 1998, fourth quarter of 1998 and third quarter of 1999. At
June 30, 2001 approximately $3.4 million of the non-recurring charges remain for
facility lease obligations and other payments. We anticipate that the majority
of these charges will be used over the next 12 months.

(4)  Changes in Stockholder's Equity

     In addition to the effects of the Company's results of operations which
reduced the retained deficit, the Company's paid in capital increased in 2001 on
a year to date basis due to a $2.9 million contribution of tax benefits
generated by the Company's parent corporation.

(5)  Segment Information

     Operating segments represent components of the Company's business which 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, Network Services and Care Management Services groups.

     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. Health Services
owns all the operating assets of the occupational health care centers, including
leasehold improvements and medical equipment.

     The Network Services segment reflects those businesses that involve the
review and repricing of provider bills and which are routinely compensated based
on the degree to which the Company achieves savings for its clients. This
segment includes our specialized preferred provider organization, provider bill
review, out-of-network bill review and first report of injury services.

     Care Management Services reflects the Company's professional services aimed
at curtailing the cost of workers' compensation and auto claims through field
case management, telephonic case management, independent medical examinations
and utilization management. These services also concentrate on monitoring the
timing and appropriateness of medical care.

Overview

     Concentra Operating Corporation (the "Company") is a leading provider of
healthcare management and cost containment services to the workers'
compensation, auto insurance and disability insurance markets. The Company is
also a leading provider of out-of-network medical claims review to the group
health marketplace and performs non-injury healthcare services. Our
comprehensive services are organized into the following segments: Health
Services, Network Services and Care Management Services.

     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, 2001 and 2000, Health Services derived 66.6% and 63.6% of
its net revenue from the treatment of work-related injuries and illnesses,
respectively and 33.4% and 36.4% of its net revenue from non-injury related
medical services, respectively.

     The Network Services segment reflects those businesses that involve the
review and repricing of provider bills and which are routinely compensated based
on the degree to which the Company achieves savings for its clients. This
segment includes our specialized preferred provider organization, provider bill
review, out-of-network bill review and first report of injury services.

     Care Management Services reflects the Company's professional services aimed
at curtailing the cost of workers' compensation and auto claims through field
case management, telephonic case management, independent medical examinations
and utilization management. These services also concentrate on monitoring the
timing and appropriateness of medical care.

Results of Operations for the Three and Six Months Ended June 30, 2001 and 2000

Revenue

     Total revenue increased 11.3% in the second quarter of 2001 to $211.9
million from $190.3 million in the second quarter of 2000 due to growth in all
business segments. The largest portion of this growth came from Health Services,
which increased 9.0% in the second quarter of 2001 to $112.3 million from $103.0
million in the second quarter of 2000. Network Services provided a 16.6%
increase in revenue to $45.3 million in the second quarter of 2001 from $38.9
million in the same quarter of the prior year. Care Management Services also
contributed to the quarter's growth in revenue with an 11.9% increase to $54.3
million as compared to $48.5 million in the second quarter of 2000.

     Total revenue for the six months ended June 30, 2001 increased 10.4% to
$410.0 million from $371.4 for the six months ended June 30, 2000. Health
Services' revenue increased 9.5% for the six months ended June 30, 2001 to
$216.0 million from $197.3 million for the same period in the prior year.
Network Services' revenue increased 9.9% to $87.7 million for the first half of
2001 from $79.8 million for the first six months of 2000. For the first six
months of 2001, Care Management Services' revenue increased 12.6% to $106.3
million from $94.4 million.

     Health Services' revenue growth resulted primarily from the acquisition of
practices and an increase in average revenue per visit. The increased revenue
from new center growth was a result of 11 new occupational health centers
acquired in the first half of 2001. The number of patient visits to Health
Services' centers in the second quarter of 2001 increased 1.3% in total compared
with the second quarter of 2000 and decreased 2.5% on a same-market basis. For
the six months ended June 30, 2001, visits increased 4.1% in total and showed no
change when measured on a same market basis as compared to the same period in
the prior year. During the current year, we are experiencing a decline in the
rate of growth of non-injury related visits as compared to prior years, due
primarily to the decrease in the number of new-hires being made by our clients.
This lower level of new-hire activity has reduced the number of pre-employment
drug screens and physical exams from the levels we experienced when the economy
was stronger. We currently believe our growth in non-injury services will return
once the nationwide economy improves and new-hire activity increases. On a same-
market basis, average revenue per visit increased 7.0% and 5.6% for the quarter
and six months, respectively, as compared to the same respective periods in
2000. A higher relative mix of injury-related visits as compared to non-injury
related visits contributed to this improvement. The average fees charged for
injury visits are generally higher than those charged for non-injury related
visits. Injury-related visits constituted 49.4% and 49.5% of total visits in the
second quarter and first half of 2001, respectively, as compared to 47.8% and
48.4% for the same respective periods in the prior year. We currently anticipate
that the percentage of injury visits will remain relatively stable during the
next several quarters.

                                       10
<PAGE>

     The increase in Network Services revenue is largely attributed to growth in
out-of-network group health medical bill review revenue in the second quarter
and first half of 2001 over the same periods in 2000. This growth is primarily
due to increased bill volume and the rate of savings achieved through our review
of medical charges. Also contributing to this growth was an increase in revenue
from our specialized preferred provider organization network access services and
our retrospective medical bill review services.

     Revenue growth for Care Management Services was due primarily to increases
in case management services and, to a lesser extent, increases in independent
medical examinations. Higher referral rates and average hourly prices in the
second quarter and first half of 2001 as compared to the same periods in 2000
were the primary factors that contributed to our field case management growth.
At this time, we anticipate continuing moderate growth in this business segment.

Cost of Services

     Total cost of services increased 9.5% in the second quarter of 2001 to
$161.2 million from $147.2 million in the second quarter of 2000. The largest
portion of this cost of services increase came from Health Services, which grew
8.2% in the second quarter of 2001 to $86.7 million from $80.1 million in the
second quarter of 2000. Cost of services for Care Management Services increased
12.0% to $47.3 million in the second quarter of 2001 from $42.2 million in the
same period of 2000. Network Services growth in cost of services of 9.5% to
$27.3 million in the second quarter of 2001 from $24.9 million in the second
quarter of 2000 also contributed to the increased cost of services.

     For the six months ended June 30, 2001, total cost of services increased
9.2% to $318.2 million from $291.5 million for the same period in the prior
year. Health Services' cost of services increased 9.5% to $172.1 million from
$157.1 million for first six months of 2001 and 2000, respectively. Cost of
services for Care Management Services grew by 10.2% to $92.6 million in the
first half of 2001 from $84.0 million for the first half of 2000. Network
Services' cost of services increased by 6.3% to $53.5 million from $50.4 million
for the six months ended June 30, 2001 and 2000, respectively.

     Total gross profit increased 17.5% to $50.7 million in the second quarter
of 2001 from $43.1 million in the second quarter of 2000. For the first six
months of 2001, the total gross profit margin increased 14.8% to $91.8 million
from $80.0 for the same period of 2000. As a percentage of revenue, gross profit
increased to 23.9% and 22.4% in the second quarter and first half of 2001,
respectively, from 22.7% and 21.5% in the same respective periods of 2000. This
percentage increase is primarily due to Network Services' gross profit increase
to 39.8% and 38.9% in the second quarter and first half of 2001, respectively
from 35.9% and 36.9% in the same respective periods of 2000. Also, Health
Services' gross profit increased to 22.8% in the second quarter of 2001 from
22.2% in the second quarter of 2000 and remained consistent at 20.3% for the
first half of 2001 and 2000. Care Management Services gross profit of 12.9% in
the second quarter of 2001 was consistent with the same prior year period and
increased to 13.0% for the first half of 2001 from 11.0% for the first half of
2000.

     Health Services' slight gross profit increase for the second quarter of
2001 from the same period in 2000 relates primarily to the impact of increased
revenue per visit, expansion in the number of health centers and improved
management of expenses.

     The increase in Network Services' gross profit primarily relates to
increased revenue from our out of network bill review services. The costs of
providing these services are relatively stable irrespective of short-term
revenue changes, which resulted in an increase in the relative gross profit
achieved during the second quarter.

     Care Management Services' gross profit increase for first six months of
2001 over the same prior year period is primarily due to increased revenue from
our independent medical examinations and case management services. At this time,
we anticipate that the margin percentage will continue to remain consistent with
historical levels.

General and Administrative Expenses

     General and administrative expenses increased 22.6% in the second quarter
of 2001 to $19.9 million from $16.2 million in the second quarter of 2000, or
9.4% and 8.5% as a percentage of revenue for the second quarters of 2001 and
2000, respectively. For the first six months of 2001, general and administrative
expenses increased 16.4% to $38.6 million, or 9.4% of revenue, from $33.2
million, or 8.9% of revenue, in the first half of 2000. This increase was

primarily due to our continued investment in support personnel and information
technology in order to support recent and planned growth.

Amortization of Intangibles

     Amortization of intangibles increased 4.2% in the second quarter of 2001 to
$3.8 million from $3.7 million in the second quarter of 2000, or 1.8% and 1.9%
as a percentage of revenue for the second quarters of 2001 and 2000,
respectively. For the six months ended June 30, 2001, amortization of
intangibles increased 3.7% to $7.5 million, or 1.8% of revenue, from $7.2
million, or 1.9% of revenue for the first six months of 2000. The increase is
primarily the result of the amortization of goodwill, associated with
acquisitions by Health Services.

Interest Expense

     Interest expense decreased $0.8 million in the second quarter of 2001 to
$16.8 million from $17.6 million in the second quarter of 2000. For the first
six months of 2001 and 2000, interest expense was $33.7 million. This decrease
in the second quarter of 2001 from the same period in 2000 is due primarily to
lower interest rates in 2001. We currently expect interest expense for 2001 to
be approximately $69.0 million. As of June 30, 2001, approximately 65.9% of our
debt contains floating rates. Although we utilize interest rate hedges to manage
a significant portion of this market exposure, rising interest rates would
negatively impact our results. See "Liquidity and Capital Resources" and "Item
3. Quantitative and Qualitative Disclosures About Market Risk."

Interest Rate Hedging Arrangements

     We utilize interest rate collars to reduce our exposure to variable
interest rates and, in part, because it is required under our current senior
secured credit agreement. These collars generally provide for certain ceilings
and floors on interest payments as the three-month LIBOR rate increases and
decreases, respectively. The changes in fair value of this combination of
ceilings and floors are recognized each period in earnings. We recorded a gain
of $3.6 million and a loss of $3.1 million in the second quarter and first half
of 2001, respectively, as compared to losses of $2.5 million and $0.9 million
for the same respective periods of the prior year. These gains and losses were
based upon the change in the fair value of our interest rate collar agreements.
This earnings impact and any subsequent changes in our earnings as a result of
the changes in the fair values of the interest rate collars are non-cash charges
or credits and do not impact cash flows from operations or operating income.
There have been, and may continue to be, periods with significant non-cash
increases or decreases to our earnings relating to the change in the fair value
of the interest rate collars. Further, if we hold these collars to maturity
(2004 and 2005), the earnings adjustments will offset each other on a cumulative
basis and will ultimately equal zero.

Provision for Income Taxes

     We recorded a tax provision of $5.8 million and $5.2 million in the second
quarter and first six months of 2001, which reflects effective tax rates of
42.9% and 60.6%, respectively.  For the second quarter and first six months of
2000, we recorded a tax provision of $1.9 million and $2.8 million,
respectively, reflecting effective tax rates of 62.7% and 56.0%, respectively.
The effective rate differs from the statutory rate due to the non-deductibility
of goodwill and certain fees and expenses associated with acquisition costs, and
to a lesser extent, the impact of state income taxes. Due to the Company's
current relationship of taxable book income as compared to net income, its
effective tax rate can vary significantly from one period to the next depending
on relative changes in net income. As such, the Company currently expects
further variation in its effective tax rate during the remainder of 2001.

Liquidity and Capital Resources

     We provided $30.3 million in cash from operating activities for the six
months ended June 30, 2001, and provided $9.0 million for the same six month
period last year. The increase in cash from operating activities in the first
half of 2001 as compared to the same period in 2000 was primarily a result of
increased earnings, improved capital management and better collections on
accounts receivable. During the first half of 2001, $2.8 million of cash was
provided by working capital, primarily related to increases in accounts payable
and accrued expenses of $13.1 million, partially offset by an increase in
accounts receivable of $10.3 million. Accounts receivable increased primarily
due to continued revenue growth, while accounts payable and accrued expenses
increased primarily due to the timing of certain payments, including payment of
accrued interest on the Company's 13% Subordinated Notes and payroll-related
items.

     During the six months ended June 30, 2001, we made approximately $0.4
million in cash payments related to the non-recurring charges that occurred in
the second quarter of 1998, fourth quarter of 1998 and third quarter of 1999. At
June 30, 2001 approximately $3.4 million of the non-recurring charges remain for
facility lease obligations and other payments. We anticipate that the majority
of these charges will be used over the next 12 months.

     For the six months ended June 30, 2001, we used net cash of $17.0 million
in connection with acquisitions and $13.1 million of cash to purchase property
and equipment during the first half of 2001, the majority of which was spent on
new computer hardware and software technology, as well as leasehold
improvements. Cash flows from investing activities also included $0.7 million of
cash received from the sale of internally-developed software. As required by
accounting pronouncements, the proceeds were offset against the amount
capitalized on the balance sheet and were not recognized as revenue. Cash flows
used in financing activities of $2.1 million was due to debt repayments.

     We were in compliance with our covenants, including our financial covenant
ratio tests, in the second quarter of 2001. At June 30, 2001, we had no
borrowings outstanding under our revolving credit facility.

     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 the level or
volatility of interest rates. In order to hedge this risk under our current
credit agreements, we have utilized interest rate collars. 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. However, the same hypothetical 10% movement in interest
rates would change the fair value of our hedging arrangements and pretax
earnings by $2.8 million as of June 30, 2001. For more information on the
interest rate collars, see Note 5 in the audited consolidated financial
statements of the Company's 2000 Form 10-K.
