CONCENTRA OPERATING CORPORATION REPORTS FOURTH QUARTER RESULTS

     ADDISON, Texas, February 13, 2001 - Concentra Operating Corporation
("Concentra") today announced financial results for the fourth quarter and year
ended December 31, 2000.  Due primarily to a strong performance in the Company's
Health Services and Specialized Cost Containment service lines, Concentra
reported $26,532,000 in EBITDA for the fourth quarter, representing an 18%
increase over the same period last year.

     Revenue for the fourth quarter rose 7% to $187,953,000 from $175,255,000
reported in the fourth quarter of 1999.  Operating income increased 28% to
$15,518,000 compared with $12,157,000 for the same period last year.  Revenue
for the year ended December 31, 2000, rose 10% to $752,161,000 from $681,412,000
in 1999.  Operating income for 2000 increased 13% to $77,618,000 compared with
$68,672,000, excluding non-recurring charges, reported last 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 18% to
$26,532,000 in the fourth quarter of 2000 compared with $22,449,000 reported for
the same period last year.  For 2000, EBITDA totaled $119,300,000, representing
an increase of 14% from $104,695,000 in the year-earlier period.

     After reflecting the non-operating effects of adopting new accounting
standards for the valuation of interest rate hedging arrangements and revenue
recognition, the Company reported a net loss for the fourth quarter and year
ended December 31, 2000, totaling $9,568,000 and $6,551,000, respectively.  In
1999, Concentra reported net losses of $2,028,000 for the fourth quarter and
$26,504,000 for the year, with the latter amount including a non-recurring
charge of $54,419,000, or $45,884,000 after tax, related to the Company's re-
capitalization transaction in August 1999.

     At December 31, 2000, Concentra had no borrowings outstanding under its
$100,000,000 revolving credit facility.   During the fourth quarter of 2000, the
Company repaid $19,500,000 borrowed under this facility and ended the year with
approximately $6,549,000 in cash and cash equivalents.

     Commenting on the results, Daniel J. Thomas, President and Chief Executive
Officer, said, "The year 2000 was a defining period for the Company, and we are
very pleased by the overall progress Concentra made during the year.  As has
been the case throughout 2000, Health Services again led our year-over-year
growth in the fourth quarter.  We were also aided by a strong performance in our
Specialized Cost Containment service line."

     Thomas pointed out that Concentra's Health Services business posted solid
growth during the fourth quarter of the year despite the challenges of inclement
weather across many of its markets. Severe weather conditions forced closings
and reduced operating times at many centers in such markets as Chicago, Detroit,
Dallas, and across the Midwest. Additionally, a shortage of flu vaccine reduced
visit counts in November and December. "Clearly, these challenges affected the
level of patient visits we experienced during the fourth quarter and our results
would have been even stronger were it not for these factors," he added.

     Same-market revenue for Health Services rose 6.3% in the fourth quarter and
8.8% for the year to date. These gains primarily related to a higher number of
patient visits. During the fourth quarter, 51% of the total visits to
Concentra's occupational healthcare centers related to non-injury care compared
with 50% in the fourth quarter of 1999. Concentra ended 2000 with 216
occupational health centers located in 64 markets in 32 states.

     Thomas also noted that Concentra's Specialized Cost Containment services
posted solid growth and improved EBITDA for the fourth quarter of 2000.  "We are
pleased with the contributions of our Concentra Preferred Systems, Provider Bill
Review and Medical Exams businesses to our fourth quarter results.  We've made
excellent progress in these business units during 2000," he said.

     Separately, Thomas announced that Concentra's parent company has changed
its name from Concentra Managed Care, Inc. to Concentra, Inc.  "We believe this
name more appropriately reflects the employer and insurance services nature of
our business," said Thomas.

     In the fourth quarter of 2000, Concentra adopted the provisions of
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities," pursuant to which the Company recorded a
non-cash, non-operating charge of $6,822,000 prior to taxes to reflect a
reduction in the fair value of the Company's interest rate hedging arrangements
in accordance with this new standard.   The Company also said it will restate
its first three quarters of operations during 2000 to reflect the periodic
adjustment of its interest rate hedging arrangements to fair value in each of
those periods.   The periodic non-cash increases and decreases in non-operating
income from these valuation adjustments relate to the Company's interest rate
hedging agreements entered into in connection with its variable-rate $475
million Senior Secured Credit Facility.     If the Company holds these interest
rate hedging arrangements to maturity, the cumulative effect of these periodic
earnings adjustments will ultimately equal zero.

     Additionally, Concentra implemented, retroactive to January 1, 2000, the
new Securities and Exchange Commission's Staff Accounting Bulletin No. 101,
"Revenue Recognition in Financial Statements," pursuant to which the Company
recorded a one-time, non-operating charge of $2,817,000 net of tax for the
cumulative effect of the change in accounting for revenue from certain of its
post-payment service offerings.

call can be accessed at www.streetevents.com.  The simulcast will begin at
