   CONCENTRA OPERATING CORPORATION REPORTS SECOND QUARTER RESULTS

     ADDISON, Texas, August 1, 2000 - Concentra Operating Corporation
("Concentra") today announced financial results for the second quarter and six-
month period ended June 30, 2000.  Revenues for the second quarter rose 9% to
$190,348,000 from $174,088,000 reported in the same period last year.  Operating
income remained essentially unchanged for the second quarter at $23,216,000
versus $23,928,000 in the prior year.  As expected, the impact of higher
interest expense, related to new credit facilities put in place to facilitate
Concentra's August 1999 recapitalization, reduced second quarter net income to
$2,397,000 as compared with $11,526,000 in the comparable period last year.

     For the six months ended June 30, 2000, revenues increased 13% to
$371,444,000 as compared with $329,499,000 reported for the same period last
year.  Operating income increased 4% to $39,585,000 versus $38,144,000 reported
for the first half of 1999.  Higher interest expense was the principal reason
for the Company's lower net income of $2,628,000 for the first six months of
2000 as compared to net income of $17,594,000 for same period in the prior year.

     Earnings before interest, taxes, depreciation and amortization ("EBITDA"),
as computed in a manner consistent with the definition set forth in the
Company's $190 million Series A Senior Subordinated Notes, increased 4% to
$33,478,000 in the second quarter of 2000 versus $32,180,000 reported for the
comparable 1999 period and was up 28% as compared to the first quarter of 2000.
Through the first half of 2000, EBITDA was $59,664,000, representing an increase
of 10% over the $54,215,000 reported for the same period last year.

     Commenting on the results, Daniel J. Thomas, President and Chief Executive
Officer of Concentra, said, "We are pleased to report on the Company's continued
progress.  During the second quarter, Concentra's revenue growth exceeded our
previous expectations, largely reflecting the strength of our Health Services
operations and improving stability in our Field Case Management division.  These
positive trends, together with improved expense control at all levels of the
Company, helped us expand our operating cash flows."

     Thomas explained that Concentra's Health Services division continues to
serve as an important catalyst for the Company's ongoing growth in revenues,
profits and cash flow.  With quarterly revenues topping the $100 million mark
for the first time ever, this division accounted for 54% of Concentra's total
second quarter revenues.  Concentra Health Services, the nation's largest
network of occupational healthcare centers with 215 centers located in 63
markets in 32 states, witnessed strong internal growth during the second quarter
as same-market revenues rose 9.9% as compared to the same period last year.  For
the year-to-date period, same-market revenues increased 8.9%.  Increased visits
are driving this growth, with solid gains for injury-related care but even
faster growth in non-injury visits as clients increasingly look to Concentra to
provide pre-employment related testing, such as physical examinations, substance
abuse testing and other similar services.  This continues a trend that Concentra
has experienced for several quarters, with non-injury care accounting for 52% of
the visits to Concentra's occupational healthcare centers in the second quarter,
up from 50% in the second quarter of last year.

     "While we are encouraged by the continuing momentum of our Health Services
operations, we also recognize that some of our specialized cost containment
services, which have been among the fastest growing services we offer, did not
sustain this rapid pace in the second quarter," Thomas continued.  "As
anticipated, Concentra Preferred Systems produced lower revenues during the
current quarter than it did during the second quarter of 1999, primarily due to
the significant amount of sales from the Company's contract compliance service
offering that were recorded during the prior year.  These strong prior-year
sales make the second quarter of this year difficult to compare to the prior
year.  While we have been continuing to cultivate new sales of contract
compliance and other post-payment service initiatives during 2000, these sales
were not sufficient in the second quarter to replicate the levels we initially
achieved last year at this time with sales to several large clients," Thomas
said.  Thomas also noted that Concentra Preferred Systems' growth strategy
during coming quarters is focused on sales of these new service offerings to
several key clients.  "As we approach 2001, and our traditional service
offerings continue to mature, we see the opportunity for sustaining our
traditional growth rates through a strategic broadening of Concentra Preferred
Systems' service offerings," he said.

     During the second quarter, the amount outstanding under Concentra's $100
million revolving credit facility declined to $10.0 million at June 30, 2000
from $24.5 million at March 31, 2000, primarily as a result of a significant
increase in cash flows from operating activities during the quarter and a
reduction in the Company's cash balances.  Due to seasonal effects on the
Company's accounts receivable, personnel expenditures and interest payments, the
Company currently anticipates an increase in revolver borrowings during the
third quarter.
