                        CONCENTRA OPERATING CORPORATION
                   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, 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., 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

    On August 29, 1997, CMC 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 accompanying consolidated financial statements as of March 31, 2000,
and December 31, 1999, and for three months ended March 31, 2000, and March 31,
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 March 31, 2000, and December
31, 1999, were $24.5 million and $4.0 million, respectively. As of March 31,
2000, and December 31, 1999, accrued interest was $5.5 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.  The
Company currently believes the amended agreement will enable Concentra to meet
the terms of the financial compliance ratios for the foreseeable future. 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 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 first 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
$337.2 million, as of March 31, 2000.  The fair value of the Company's 13%
Subordinated Notes was $138.7 million at March 31, 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 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, 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.

    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 40.5% and 44.9% of total Managed Care Services revenue for the three
months ended March 31, 2000, and 1999, respectively.

    There has not been a material change in the composition of segment
identifiable assets as of March 31, 2000, as compared to the December 31, 1999
amounts reported in the Company's 1999 Form 10-K.  Revenues from individual
customers, revenues between business segments and revenues, 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 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

    CMC 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. 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.

    Concentra Health Services, Inc. ("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 three months ended March 31, 2000 and 1999,
Health Services derived 63.5% and 63.2% of its net revenues from the treatment
of work-related injuries and illnesses, respectively and 36.5% and 36.8% of its
net revenues from non-injury related medical services, respectively.

    Concentra Managed Care Services, Inc. ("Managed Care Services") provides
specialized cost containment and field case management services designed to
reduce costs associated with workers' compensation, automobile accident and
group health claims. Managed Care Services currently derives most of its
revenues on a fee-for-service basis or percentage of savings basis.

    The specialized cost containment services we provide 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 that are
designed to reduce the cost of workers' compensation claims, automobile accident
injury claims and group health claims.

    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 the return to work.

    The following table provides certain information concerning our service

Results of Operations for the Three Months Ended March 31, 2000 and 1999

Revenues

    Our total revenue increased 16.5% in the first quarter of 2000 to $181.1
million from $155.4 million in the first quarter of 1999.  Health Services'
revenue increased 33.5% in the first quarter of 2000 to $94.3 million from $70.6
million in the first quarter of 1999.  Managed Care Services' revenue increased
2.4% in the first quarter of 2000 to $86.8 million from $84.8 million in the
first quarter of 1999 as specialized cost containment revenue increased 10.6% in
the first quarter of 2000 to $51.7 million from $46.7 million in the first
quarter of 1999 and field case management revenue decreased 7.6% in the first
quarter of 2000 to $35.2 million from $38.1 million in the first quarter of
1999.

    Health Services' revenue growth resulted primarily from the acquisition of
practices and an increase of business in existing markets.  The number of visits
to Health Services' centers in the first quarter of 2000 increased 28.5% in
total compared with the first quarter of 1999 and 8.5% on a same-market basis.

    The increase in specialized cost containment revenue growth is largely
attributable to growth in out-of-network bill review and first report of injury
services and preferred provider organization network access fees.   The decrease
in the field case management revenue is attributable to decreases in business
volume resulting primarily from customer uncertainty from our 1998 fourth
quarter reorganization and our competitors' related marketing efforts and, to a
lesser extent, from the recent "task-based" approach to service delivery.  This
new approach, where the customer selects the specific field case management
tasks we perform, has caused a reduction in the billable hours per case.

Cost of Services

    Our total cost of services increased 16.6% in the first quarter of 2000 to
$144.2 million from $123.7 million in the first quarter of 1999.  Health
Services' cost of services increased 33.2% in the first quarter of 2000 to $77.0
million from $57.8 million in the first quarter of 1999.  Managed Care Services'
cost of services increased 2.0% in the first quarter of 2000 to $67.2 million
from $65.9 million in the first quarter of 1999 as specialized cost containment
cost of services increased 7.5% to $35.4 million in the first quarter of 2000
from $32.9 million in the first quarter of 1999 and field case management cost
of services decreased 3.5% to $31.9 million in the first quarter of 2000 from
$33.0 million in the first quarter of 1999.

    Our total gross profit margin remained at 20.4% in the first quarter of 2000
compared to the first quarter of 1999.   In 1999, Health Services acquired 53
clinics in 20 acquisitions.  For the first quarter of 2000, Health Services
acquired five clinics in three acquisitions.  Historically, gross profit margins
are initially negatively impacted due to lower margins from practices recently
acquired.  However, as we have consolidated certain functions, made other staff-
related changes and increased patient volume, the margins of our acquired
practices have tended to improve.  Health Services' gross profit margin
increased slightly to 18.3% in the first quarter of 2000 compared to 18.2% in
the first quarter of 1999.

    Managed Care Services' gross profit margin increased to 22.6% in the first
quarter of 2000 from 22.2%  in the first quarter of 1999 as a result of a
specialized cost containment gross profit margin increase to 31.5% from 29.6%,
partially offset by a field case management gross profit margin decrease to 9.4%
from 13.2%.  Managed Care Services' gross profit margins increased slightly due
primarily to the success of the first report of injury and out-of-network bill
review services.  This success was partially offset by a decrease in provider
bill review and claims review gross profit margins as a result of an increase in
software maintenance fees associated with a third party software supplier and
the impact of pricing concessions previously made.  In addition, field case
management gross profit margins decreased primarily due to lower revenue
compared to the first quarter of last year. We currently expect the recent
margin decreases to stabilize.  This stabilization, however, will be dependent
on several factors, including the success of the our marketing and
management efforts.

General and Administrative expenses

    Our general and administrative expenses increased 17.3% in the first quarter
of 2000 to $16.9 million from $14.4 million in the first quarter of 1999, or
9.3% as a percentage of revenue for the first quarters of 2000 and 1999.  This
increase was primarily due to our continued investment in support personnel and
information technology.

Amortization of Intangibles

    Our amortization of intangibles increased 17.4% in the first quarter of 2000
to $3.6 million from $3.0 million in the first quarter of 1999, or 2.0% as a
percentage of revenue for the first quarters of 2000 and 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

    Our interest expense increased $11.5 million in the first quarter of 2000 to
$16.2 million from $4.7 million in the first quarter of 1999 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 $67.7 million compared to 1999 interest expense of $12.7
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
recent amendment of our credit facility.  As of March 31, 2000, approximately
68% of our debt contains floating rates. Although we utilize interest rate swaps
to manage a portion of this market exposure, our results of operations would be
negatively impacted by rising interest rates.  See "Liquidity and Capital
Resources".

Interest Income

    Our interest income decreased $1.0 million in the first quarter of 2000 to
$0.1 million from $1.1 million in the first quarter of 1999 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 $0.2 million in the first quarter of 2000
compared with a tax provision of $4.5 million in the first quarter of 1999,
which reflects effective tax rates of 45.5% and 42.5%, respectively.

Year 2000 Disclosure

    We completed our Year 2000 program in the fourth quarter of 1999 by testing
and upgrading (when necessary) our systems.  As a result of those planning and
implementation efforts, we have not experienced, and do not anticipate
experiencing, any significant issues, internally or externally, with respect to
our operations as a result of the Year 2000 issue.  Although we believe we have
completed this program successfully, there can be no assurance that this program
will continue to be successful in remediating the impact of the Year 2000 issue.

                                       13

Liquidity and Capital Resources

    We used $15.0 million in cash for operating activities for the three months
ended March 31, 2000, and generated $7.4 million for the same three month period
last year.    During the first three months of 2000, $24.8 million of cash was
used for working capital purposes, primarily related to an increase in accounts
receivable of $5.3 million and a decrease in accounts payable and accrued
expenses of $19.2 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% Subordinated Notes and payroll-related items.

    During the quarter ended March 31, 2000, we made approximately $1.0 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 $4.0 million in cash
payments will be made related to these non-recurring charges. These expenditures
are anticipated to consist of $1.5 million of fees and other expenses related to
the 1999 Merger, $0.5 million of employee-related costs, $0.6 million of
facility-related costs, $1.3 million of costs associated with settling claims on
certain expired contracts and $0.1 million of other costs.

    For the three months ended March 31, 2000, we used net cash of $2.7 million
in connection with acquisitions and $7.7 million of cash to purchase property
and equipment during the first quarter of 2000, the majority of which was spent
on new computer hardware and software technology.

     Cash flows provided by financing activities of $17.9 million was due
primarily from $20.5 million in additional borrowings under our revolving credit
facilities, partially offset by $1.0 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 first quarter of 2000.  At March 31, 2000, we had borrowings
outstanding under our revolving credit facility of $24.5 million.

     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 5 in the audited consolidated
financial statements of the Company's 1999 Form 10-K.
