     THE FOLLOWING SUMMARY CONTAINS A GENERAL DISCUSSION OF OUR BUSINESSES, THE
EXCHANGE OFFER AND SUMMARY FINANCIAL INFORMATION. WE ENCOURAGE YOU TO READ THIS
ENTIRE PROSPECTUS FOR A MORE COMPLETE UNDERSTANDING OF CONCENTRA OPERATING
CORPORATION, THE SUBSIDIARY GUARANTORS AND THE EXCHANGE OFFER. CONCENTRA
OPERATING BECAME A WHOLLY-OWNED SUBSIDIARY OF CONCENTRA MANAGED CARE, INC. ON
AUGUST 17, 1999 AS A RESULT OF THE MERGER OF CONCENTRA AND YANKEE ACQUISITION
CORP.

                                   THE COMPANY

     We are the largest company dedicated primarily to serving the occupational
healthcare market. We provide initial treatment for approximately 4% of
workplace injuries in the United States and perform non-injury occupational
healthcare services for over 80,000 local employers. We provide specialized cost
containment and field case management services to over 2,000 customers across
the United States and Canada, including most of the major underwriters of
worker's compensation insurance, third-party administrators and self-insured
employers. We are also the largest provider of out-of-network bill review
services to the group health marketplace. We offer a range of healthcare-related
services to employers, insurers and third-party administrators of all sizes and
are compensated for our services on a non-risk-bearing, fee-for-service or
percentage-of-savings basis. Less than 0.5% of our revenues are dependent on
Medicare or Medicaid reimbursement. Each of our services and the general
industries in which we operate are described in more detail below.

     Our services reduce the customer's healthcare costs by:

     o  efficiently managing the application of care and the return-to-work
        process, thereby providing appropriate medical care while reducing the
        non-medical costs associated with a claim; and

     o  using sophisticated cost containment techniques to determine the proper
        pricing of care once it has been administered.

     We believe that by both providing care and offering claims management
services, we are in a unique position to provide a full range of services,
separately or as a bundled group of services, to national or regional accounts
and local employers. In addition to the occupational healthcare and group health
markets, we also provide cost containment services to the auto insurance market
as well as social security disability advocacy services to the long-term
disability insurance market. In 1998, we generated revenues and Adjusted EBITDA,
as described below, of $611.1 million and $111.7 million, respectively.

                                 INDUSTRY REVIEW

OCCUPATIONAL HEALTHCARE

     Occupational healthcare services consist of two primary components:

     o  workers' compensation injury care and related services, and

     o  non-injury occupational healthcare services related to employer needs or
        statutory requirements.

     Workers' compensation is a state-mandated, comprehensive insurance program
that requires employers to fund all medical expenses, lost wages and other costs
resulting from work-related injuries and illnesses with no co-payment from the
employee. Because each state is responsible for implementing and regulating its
own program, workers' compensation regulations can vary widely on a
state-by-state basis and are often highly complex. According to the Workers'
Compensation Monitor data published in the 1998 Workers' Compensation Year Book,
estimated spending for workers' compensation claims increased to approximately
$92.7 billion in 1996 from approximately $66.7 billion in 1991, representing a
6.8% compound annual growth rate. Of that amount, we believe that medical costs
comprise approximately 40% of the total costs of workers' compensation with lost
time wages, administrative


                                       3
<PAGE>


expenses and legal costs making up the remaining 60%. We believe that workers'
compensation costs will continue to rise primarily because of:

     o  broader definitions of work-related injuries and illnesses covered by
        workers' compensation laws;

     o  the shifting of medical costs from health insurance plans to the
        workers' compensation system;

     o  an aging work force;

     o  the continued requirement that employers pay all of an employee's cost
        of medical treatment, without any employee co-payment or deductible, and
        related lost wages and non-medical costs; and

     o  the under-use to date of comprehensive programs to contain costs in the
        workers' compensation system.

     Non-injury occupational healthcare services include employment-related
physical examinations, drug and alcohol testing, functional capacity testing,
and other related programs designed to meet specific employer needs. Non-injury
healthcare services also include programs to assist employers in complying with
a continuously expanding list of federal and state requirements, including
hearing conservation programs, toxic chemical exposure surveillance and
monitoring programs, and Department of Transportation and Federal Aviation
Administration-mandated physical examinations. Federal laws governing health
issues in the workplace, including the Americans with Disabilities Act, have
increased employers' demand for healthcare professionals who are experts in the
delivery of these regulated services.


COST CONTAINMENT

     Cost containment techniques are intended to control the cost of healthcare
services and to measure the performance of providers through intervention and
on-going review of services proposed and actually provided. Managed care
techniques were originally developed to stem the rising costs of group
healthcare. Historically, employers were slow to apply managed care techniques
to workers' compensation costs primarily because the aggregate costs are
relatively small compared to those associated with group health benefits and
because state-by-state regulations related to workers' compensation are more
complex than those related to group health. However, in recent years, employers
and insurance carriers have been increasing their focus on applying managed care
techniques to control their workers' compensation costs.

     Worker's compensation cost containment services include two broad
categories:

     o  specialized cost containment services; and

     o  field case management services.


GROUP HEALTH

     According to the Health Insurance Association of America, private health
insurance claims payments increased to $281.7 billion in 1995 from $208.9
billion in 1990, representing a 6.2% compound annual growth rate. Of that
amount, we believe that approximately 10% are for out-of-network services. All
healthcare payors have out-of-network exposure due to healthcare claims that are
outside their coverage area or network either as a matter of choice on the part
of the insured or as a result of geographic circumstances where the insured does
not have local access to contracted providers. Out-of-network healthcare claims
expose payors to greater incidence of over-use, cost-shifting, omission of
appropriate discounts and possible billing errors. Because these charges are
largely unrestrained by cost containment strategies, we believe they will
continue to increase more quickly than overall group healthcare costs.


                                       4
<PAGE>


                                  OUR SERVICES

     With healthcare costs rising, we believe that payors will seek to increase
the use of cost saving strategies, such as those we offer, to minimize these
costs. Our comprehensive services are comprised of three distinct categories:

     o  occupational healthcare services;

     o  specialized cost containment services; and

     o  field case management services.

     We provide healthcare services through our network of 201 owned and managed
occupational healthcare centers, located in 60 markets in 32 states as of
November 1, 1999. As a primary starting point for the provision of care in the
workers' compensation market, our occupational healthcare centers are designed
to efficiently provide quality care to patients while also providing an entry
point for our other cost containment services. Healthcare services include
injury care and physical therapy services for work-related injuries and
illnesses, physical examinations, substance abuse testing and certain other loss
prevention services. In 1998, revenues from healthcare services represented
approximately 42% of our total revenues.

     Specialized cost containment services are comprised of first report of
injury, telephonic case management, utilization management, both in- and
out-of-network bill review, preferred provider organization network access,
independent medical exams and peer reviews. These specialized cost containment
services are designed to monitor the timing and appropriateness of medical care,
as well as the proper pricing for that care. These services are primarily
provided to the workers' compensation market, except for out-of-network bill
review which we provide to the group health market. We are currently expanding
our out-of-network bill review services to the workers' compensation and auto
insurance markets. In 1998, revenues from specialized cost containment services
represented approximately 30% of our total revenues.

     We provide field case management services to a national customer base using
approximately 1,000 full-time field case managers. Field case management
services involve working on a one-on-one basis with injured employees and aiding
communication among their various healthcare professionals, employers and
insurance company adjusters. Field case management services are designed both to
assist in maximizing medical improvement and, where appropriate, to expedite
return to work. In 1998, revenues from field case management services
represented approximately 28% of our total revenues.

                              OUR BUSINESS STRATEGY

     We intend to take advantage of our national presence by providing a full
range of comprehensive healthcare management and cost containment services. Our
strategy includes the following elements:

     EMPHASIZE EARLY INTERVENTION SERVICES. We intend to increase our emphasis
of early intervention services through increased development and marketing of
our first report of injury, utilization management, telephonic case management,
occupational healthcare center and preferred provider organization services.
Early intervention allows us to promptly identify cases that have the potential
to result in significant expenses, particularly lost time, administrative or
legal expenses, and to take appropriate measures to control these expenses
before they are incurred. In addition, we believe that providing early
intervention services generally results in our obtaining earlier access to
claims files. Such earlier access improves our opportunity to provide the full
range of our healthcare management and cost containment services, which
typically results in a lowering of the total cost of a claim.

     CONTINUE TO ACQUIRE AND DEVELOP OCCUPATIONAL HEALTHCARE CENTERS AND EXPAND
HEALTHCARE NETWORK. Our strategy is to continue to develop clusters of
occupational healthcare centers in new and existing geographic markets through
strategic joint ventures in addition to the acquisition and development of
occupational healthcare centers. In selected markets in which a hospital
management company, hospital system or other healthcare provider has a
significant presence, we may focus our expansion efforts on joint ventures or
management contracts. We intend to continue to organize our occupational
healthcare centers in each market into clusters in order to serve employers,
payors


                                       5
<PAGE>


and workers more effectively. This also serves to leverage management and other
resources and to facilitate the development of networks of affiliated physicians
and other healthcare providers. In addition, through our preferred provider
organization, we intend to continue to expand our networks of specialists,
hospitals and other healthcare providers. These networks together with our
occupational healthcare centers are designed to efficiently provide quality care
to patients while serving as a way to introduce our other cost containment
services.

     INCREASE MARKET PENETRATION OF OUT-OF-NETWORK BILL REVIEW SERVICES. We
intend to further expand our reach into the group health marketplace by offering
customers our comprehensive out-of-network bill review services. We plan to
emphasize on-site personnel and electronic claims screening techniques which in
the past have significantly
increased our access to claims from individual
clients. We believe that we are the market leader in out-of-network bill review
in the group health marketplace and are expanding our services into the workers'
compensation market in states that have not established fee schedules. We
believe that expansion of these services represents a significant opportunity
for us in the future.

     CONTINUE TO INTEGRATE AND ENHANCE INFORMATION SYSTEMS AND TECHNOLOGY. We
intend to continue to develop our information systems to make more effective use
of our extensive proprietary knowledge base relating to workplace injuries,
treatment protocols, outcomes data and the workers' compensation system's
complex web of regulations. We expect that these enhanced information systems
will enable us to improve referrals among our full range of services, streamline
patient care and enhance outcomes reporting. This will make our operations more
efficient while improving our ability to demonstrate the costs savings our
services provide to our clients.

     CAPITALIZE ON NATIONAL ORGANIZATION AND LOCAL MARKET PRESENCE. We believe
that national and regional insurance carriers, third party administrators and
self-insured employers will benefit from our ability to provide a full range of
healthcare management and cost containment services on a nationwide basis. We
offer these large payors a solution to all of their healthcare management and
cost containment needs from a company that is adept at understanding and working
with varied and complex state legislative environments. Our national
organization of local service locations allows us to meet the needs of these
large, national payors while maintaining the local market presence necessary to
monitor changes in state-specific regulations and to facilitate case resolution
through locally provided managed care services. Our national marketing personnel
intend to continue to target these large payors to expand our customer base. In
addition, we believe we are well-positioned to capitalize on the relationship
developed through our national and local marketing efforts by cross-selling our
full range of services to our existing customers.

                                THE TRANSACTIONS

     GENERAL. On August 17, 1999, Yankee Acquisition Corp., a new Delaware
corporation formed by Welsh, Carson, Anderson & Stowe VIII, L.P., merged with
and into Concentra. Immediately after the merger, Concentra contributed all of
its assets, including all of the shares in its subsidiaries, to Concentra
Operating. As a result of the merger, each outstanding share of Concentra common
stock, other than those held by Yankee, were converted into the right to receive
$16.50 in cash.

     The merger was accounted for as a recapitalization in which the historical
basis of our assets and liabilities was not affected and no new goodwill related
to the merger was created. As a result of the merger, existing stockholders of
Concentra at the time of the merger, other than Yankee, received an aggregate of
approximately $677.4 million for all of the outstanding shares of Concentra
common stock. In addition, Concentra repurchased approximately $327.8 million of
its outstanding 4.5% convertible subordinated notes due 2003 and 6.0%
convertible subordinated notes due 2001 for $328.3 million including accrued
interest and refinanced and replaced its existing credit facilities.

     The merger and repurchase of the convertible subordinated notes were
financed by:

     (1)  At Concentra Operating:

          o  $375.0 million of borrowings by us under new term loan facilities
             which, together with our new $100.0 million revolving credit
             facility, replaced Concentra's old senior credit facility; and

          o  the net proceeds from the offering of the old notes;

     (2)  At Concentra:

          o  $110.0 million net proceeds from the issuance by Concentra of
             $216.4 million face value of senior discount debentures due 2010
             with warrants issued by Concentra exercisable for its common
             shares;

          o  an equity investment in Concentra of approximately $362.9 million
             by Welsh Carson and some affiliated investors, including the value,
             on the date of the merger, of shares and convertible notes already
             owned by Welsh Carson;

          o  a cash equity investment in Concentra of approximately $30.6
             million by affiliates of Ferrer Freeman Thompson & Co., LLC; and

          o  an equity investment in Concentra of approximately $30.2 million by
             Chase Capital Partners, DB Capital Partners, some officers and
             employees of Donaldson, Lufkin & Jenrette Securities Corporation
             and some members of Concentra's management, together we refer to
             those persons as the other investors.

                              payments on the notes when they are due, the
                              guarantor subsidiaries will be obligated to make
                              them instead.

Ranking of the Notes.......   These notes and the subsidiary guarantees are
                              senior subordinated debt. They rank behind all of
                              our and our guarantor subsidiaries' current and
                              future indebtedness, other than trade payables,
                              except indebtedness that expressly provides that
                              it is equal or subordinate in right of payment to
                              these notes and the subsidiary guarantees.

                              Assuming we had completed the offering of old
                              notes and the transactions on June 30, 1999, the
                              notes and the subsidiary guarantees would have
                              been subordinated to approximately $375.5 million
                              of senior indebtedness. No debt of ours having an

                              equal ranking with the notes and the subsidiary
                              guarantees or which is subordinate to the notes
                              and the subsidiary guarantees would have been
                              outstanding at such date.

Basic Covenants of
  the Indenture............   The indenture governing the notes places certain
                              limitations on our ability, and the ability of
                              some of our subsidiaries, to:

                              o  make investments;

                              o  pay dividends on stock or repurchase stock;

                              o  borrow money;

                              o  sell certain assets or merge with or into other
                                 companies;

                              o  use assets as security in other transactions;
                                 and

                              o  enter into transactions with affiliates.

                              For more details, see the section "Description of
                              Notes" under the caption "Certain Covenants."

Transfer Restrictions......   The new notes will have been registered under the
                              Securities Act and, therefore, will not bear
                              legends restricting their transfer. We do not
                              intend to list the notes on any securities
                              exchange.

     YOU SHOULD REFER TO THE SECTION ENTITLED "RISK FACTORS" FOR AN EXPLANATION
OF CERTAIN RISKS OF INVESTING IN THE NOTES.

                   SUMMARY OF ABILITY TO RESELL THE NEW NOTES

     We believe that the new notes issued in the exchange offer may be offered
for resale, resold or otherwise transferred by you without compliance with the
registration and prospectus delivery provisions of the Securities Act, but
only
if:

     o  you acquire the new notes in the ordinary course of business,

     o  you are not participating, do not intend to participate and have no
        arrangement or understanding with any person to participate in a
        distribution of the new notes, and

     o  you are not an affiliate of ours, as the term affiliate is defined under
        the Securities Act and which may include our executive officers and
        directors, another person having control over our operations or
        management or an entity we control.

     By executing and delivering the letter of transmittal, you will represent
to us that the above statements by you are true. If any of these statements are
untrue, you may not resell your notes unless an exemption from the registration
provisions of the Securities Act is available for the transfer or you resell
your notes in compliance with the prospectus delivery provisions of the
Securities Act.

     Each broker-dealer that is issued new notes in the exchange offer for its
own account in exchange for old notes which were acquired by the broker-dealer
as a result of market-making or other trading activities, must acknowledge that
it will deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of the new notes. A broker-dealer may use this
prospectus, as it may be amended or supplemented from time to time, for an offer
to resell, resale or similar transfer of the new notes issued to it in the
exchange offer.

          SUMMARY HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL DATA

     Set forth below are our summary historical and pro forma financial data.
The summary historical consolidated financial data for the three years ended
December 31, 1998 was derived from, and should be read in conjunction with, the
audited consolidated financial statements of Concentra and related notes to
those financial statements included elsewhere in this prospectus. The summary
historical consolidated financial data as of September 30, 1999 and for the nine
month periods ended, September 30, 1998 and 1999 were derived from the unaudited
consolidated financial statements of Concentra Operating which, in the opinion
of management, includes all adjustments, consisting only of normal, recurring
adjustments, necessary for a fair presentation of our consolidated financial
condition and results of operations as of and for those periods. The operating
results for the nine month periods ended September 30, 1998 and 1999 are not
necessarily indicative of results to be expected for the full year. The pro
forma data as of and for the periods presented give effect to the transactions
as if they were consummated at the beginning of the period indicated.

     The accompanying consolidated financial statements as of December 31, 1998
and September 30, 1999 and for the three and nine months ended September 30,
1998 and 1999 and related footnotes reflect the operating results of Concentra
through August 17, 1999 and the operating results of Concentra Operating from
August 18, 1999 through September 30, 1999. Concentra Operating is a
wholly-owned subsidiary of Concentra and they are considered entities under
common control, therefore, combined financial statements have been presented.
Earnings per share has not been reported for all periods presented, as Concentra
Operating is a wholly-owned subsidiary of Concentra and has no publicly held
shares. The summary historical consolidated financial data set forth below
should be read together with, and are qualified in their entirety by, the
"Selected Historical Consolidated Financial Data," "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the consolidated
financial statements of Concentra and notes to those financial statements
included elsewhere in this prospectus.

</TABLE>

     (a)  The 4.5% convertible subordinated notes were issued in March ($200.0
          million) and April ($30.0 million) of 1998, as such, the interest
          expense does not reflect a full year of interest expense.

     (b)  The Eurodollar Rate ("E.R.") is assumed to be 5.4% for the
          purposes of calculating interest expense. The annual effect of a 1/8%
          change in the interest rate on the $375.0 million variable rate debt
          is $0.5 million for the year ended December 31, 1998 and $0.4 million
          for the nine months ended September 30, 1999.

     (c)  The deferred finance fees of $18.0 million are being amortized over
          the weighted average life of the new debt of 8.2 years.

     (d)  Interest expense recorded through September 30, 1999 on new
          indebtedness issued in connection with the merger.

     (e)  To record the decrease in interest income due to the use of available
          cash.

     (f)  To record the tax benefit on the pro forma interest adjustments.

(3)  As a result of Concentra going private in the merger transaction, there are
     no longer publicly held shares outstanding and we believe that historical
     earnings per share information is not meaningful.

(4)  EBITDA represents net income before interest expense, interest income,
     provision for income taxes, depreciation and amortization of intangibles
     and includes depreciation and amortization of two 50% owned joint ventures
     not consolidated by Concentra. Adjusted EBITDA represents EBITDA before
     non-recurring charges. While EBITDA and Adjusted EBITDA are not intended to
     represent cash flow from operations as defined by generally accepted
     accounting principles, commonly referred to as GAAP and should not be
     considered as indicators of operating performance or alternatives to cash
     flow, as measured by GAAP, as a measure of liquidity, they are included in
     this prospectus to provide additional information with respect to our
     ability to meet our future debt service, capital expenditure and working
     capital requirements.

(5)  Cash interest expense represents interest expense recorded during the
     period excluding the amortization of debt issuance costs.


                                       15

(6)  The ratio of earnings to fixed charges is computed by dividing the sum of
     net earnings, before deducting provisions for income taxes and fixed
     charges, and adjusted for the equity in earnings of unconsolidated
     subsidiaries and related distributions, by fixed charges. Fixed charges
     consist of interest on debt, including amortization of debt issuance costs,
     and one-fourth of rent expenses, estimated by management to be the interest
     component of such rentals.

(7)  The ratio of adjusted earnings to fixed charges is computed by dividing the
     sum of net earnings, before deducting nonrecurring charges, provisions for
     income taxes and fixed charges, by fixed charges. Fixed charges consist of
     interest on debt, including amortization of debt issuance costs, and
     one-fourth of rent expense, estimated by management to be the interest
     component of such rentals.

(8)  Does not include the assets of occupational healthcare centers which were
     acquired and subsequently divested or consolidated into existing centers
     within a market.

(9)  The decline in field case management offices in 1998 is primarily due to
     the fourth quarter of 1998 reorganization which included facility
     consolidations.

(10) Represents the assets of occupational healthcare centers which were
     acquired during each period presented and not subsequently divested.

(11) Occupational healthcare centers same market revenue growth sets forth the
     aggregate net change from the prior period for all markets in which we have
     operated healthcare centers for longer than one year, excluding revenue
     growth due to acquisitions of additional centers.

                                  RISK FACTORS

     AN INVESTMENT IN THE NOTES IS SUBJECT TO A NUMBER OF RISKS. YOU SHOULD
CAREFULLY CONSIDER THE FOLLOWING FACTORS, AS WELL AS THE MORE DETAILED
DESCRIPTIONS CROSS-REFERENCED TO THE BODY OF THIS PROSPECTUS AND THE OTHER
MATTERS DESCRIBED IN THIS PROSPECTUS BEFORE DECIDING TO EXCHANGE THE OLD NOTES
FOR NEW NOTES.


RISKS APPLICABLE TO THE NOTES

          SUBSTANTIAL LEVERAGE--OUR SUBSTANTIAL INDEBTEDNESS COULD ADVERSELY
          AFFECT OUR FINANCIAL HEALTH AND PREVENT US FROM FULFILLING OUR
          OBLIGATIONS UNDER THE NOTES.

     As of September 30, 1999, our consolidated indebtedness was approximately
$566.0 million, representing approximately 107% of our total capitalization. In
addition, our business strategy calls for significant capital expenditures for
acquisition and development. The indenture governing the notes and our other
debt instruments allow us to incur additional indebtedness, including secured
indebtedness and $100.0 million of unused drawing capacity under the senior
credit facilities. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."

     Our substantial indebtedness could have important consequences to you. For
example, it could:

     o  make it more difficult for us to satisfy our obligations with respect to
        the notes;

     o  increase our vulnerability to general adverse economic and industry
        conditions;

     o  limit our ability to fund future working capital, capital expenditures,
        and other general corporate requirements;

     o  require a substantial portion of our cash flow from operations to be
        used for debt payments;

     o  limit our flexibility to plan for, or react to, changes in our business
        and the industry in which we operate;

     o  place us at a competitive disadvantage compared to our competitors that
        have less debt;

     o  limit our ability to borrow additional funds; and

     o  limit our ability to engage in various transactions such as acquisitions
        and dispositions or to make certain investments.

     Any of the above listed factors could materially adversely affect us. See
"Description of Certain Indebtedness."


         ABILITY TO SERVICE DEBT--TO SERVICE OUR INDEBTEDNESS, WE WILL REQUIRE A
         SIGNIFICANT AMOUNT OF CASH. OUR ABILITY TO GENERATE CASH DEPENDS ON
         MANY FACTORS BEYOND OUR CONTROL.

     Our ability to make payments on and to refinance our indebtedness,
including the notes, and to fund planned capital expenditures will depend on our
ability to generate cash in the future. To a certain extent, our ability to
generate cash is subject to general economic, financial, competitive,
legislative, regulatory and other factors that are beyond our control. We
believe our cash flow from operations, available cash and available borrowings
under the senior credit facilities will be adequate to meet our liquidity needs
for the foreseeable future.

     We cannot assure you, however, that our business will generate sufficient
cash flow from operations or that future borrowings will be available to us
under the senior credit facilities in an amount sufficient to enable us to pay
our indebtedness, including the notes, or to fund our other liquidity needs. We
may need to refinance all or a portion of our indebtedness, including the notes,
on or before maturity. We might not be able to refinance any of our
indebtedness, including the senior credit facilities and the notes, on
commercially reasonable terms or at all.


                                       17
<PAGE>


         SUBORDINATION--YOUR RIGHT TO RECEIVE PAYMENTS ON THESE NOTES IS JUNIOR
         TO MOST OF OUR EXISTING INDEBTEDNESS AND MOST OF OUR FUTURE BORROWINGS.
         FURTHER, THE GUARANTEES OF THESE NOTES ARE JUNIOR TO MOST OF OUR
         SUBSIDIARY GUARANTORS' EXISTING INDEBTEDNESS AND MOST OF THEIR FUTURE
         BORROWINGS.

     The notes and the subsidiary guarantees rank behind all of our and the
subsidiary guarantors' existing indebtedness, other than trade payables, and all
of our and their future borrowings, except any future indebtedness that
expressly provides that it ranks equal with, or subordinated in right of payment
to, the notes and the guarantees.

     We depend on the cash flow from our subsidiaries to meet our obligations,
including all payments on the notes. Accordingly, our ability to make payments
to holders of the notes depends on the receipt of sufficient funds from our
subsidiaries. Because of the possible terms of future indebtedness of our
subsidiaries, which may be secured by the assets of our subsidiaries, we may be
restricted in receiving funds from our subsidiaries. The indenture for the notes
permits our subsidiaries to enter into agreements which restrict dividends and
distributions to the obligors under some circumstances. See "Description of
Notes--Certain Covenants--Other Payment Restrictions Affecting Restricted
Subsidiaries."

     Although the cash distributed by our joint ventures to us or our
subsidiaries can be used to make payments on the notes, our joint ventures do
not guarantee the notes.

     As of September 30, 1999, our consolidated indebtedness was $566.0 million,
$376.0 million of which has ranked senior to the notes, and we had $95.1 million
of unused drawing capacity under the senior credit facilities. The subsidiary
guarantors have $376.0 million of indebtedness ranking senior to the guarantees.
Upon any distribution to our creditors or the creditors of the subsidiary
guarantors in a bankruptcy or similar proceeding relating to us or the
subsidiary guarantors, the holders of senior debt of Concentra Operating and the
subsidiary guarantors will be entitled to be paid in full in cash before any
payment may be made with respect to the notes or the guarantees.

     In addition, all payments on the notes and the guarantees will be blocked
in the event of a payment default on senior debt and may be prohibited for up to
179 days each year in the event of specified nonpayment defaults on senior debt.

     In the event of a bankruptcy, liquidation or reorganization or similar
proceeding relating to Concentra Operating or the subsidiary guarantors, holders
of the notes will participate with all other holders of our subordinated
indebtedness and the subsidiary guarantors in the assets remaining after we and
the subsidiary guarantors have paid all of the senior debt. Because our senior
debt must be paid first, you may receive proportionately less than trade
creditors and other senior creditors in any such proceeding. In any of these
cases, we and the subsidiary guarantors may not have sufficient funds to pay all
of our creditors, therefore, holders of the notes may receive ratably less than
trade creditors.


         RESTRICTIONS--RESTRICTIONS IMPOSED BY THE SENIOR CREDIT FACILITIES AND
         THE INDENTURE WILL MAKE IT MORE DIFFICULT FOR US TO TAKE CERTAIN
         ACTIONS.

     The senior credit facilities and the indenture restrict our ability to:

     o  make certain investments;

     o  pay dividends and make distributions;

     o  repurchase stock;

     o  incur additional indebtedness;

     o  create liens;

     o  merge or consolidate our company or any of our subsidiaries;


                                       18
<PAGE>


     o  transfer and sell assets;

     o  enter into transactions with our affiliates;

     o  enter into sale and leaseback transactions; and

     o  issue common and preferred stock of our subsidiaries.

     In addition, we must maintain minimum debt service and maximum leverage
ratios under the senior credit facilities. A failure to comply with the
restrictions contained in the senior credit facilities could lead to an event of
default which could result in an acceleration of that indebtedness before it is
otherwise due to be paid. Such an acceleration would also constitute an event of
default under the indenture relating to the notes. See "Description of Certain
Indebtedness" and "Description of Notes-Events of Default and Remedies."


         LACK OF SECURITY--BECAUSE THE NOTES ARE UNSECURED, OTHER LENDERS WILL
         HAVE PRIOR CLAIMS TO OUR ASSETS IN THE EVENT WE BECOME INSOLVENT OR ARE
         LIQUIDATED.

     In addition to being subordinate to all of our and the subsidiary
guarantors' senior indebtedness, neither the notes nor the subsidiary guarantees
are secured by any of our or the subsidiary guarantors' assets. Our obligations
under the senior credit facilities are secured by substantially all of our
assets, including assets held by our subsidiaries, other than our joint
ventures. Under the indenture for the notes, we and our subsidiaries are
permitted to incur additional secured indebtedness. If we become insolvent or
are liquidated, or if payment under the senior credit facilities is accelerated,
the lenders under the senior credit facilities would be entitled to exercise the
remedies available to a secured lender under applicable law. Therefore, our bank
lenders will have a claim on our assets before the holders of the notes. Because
the notes are unsecured, there may be no assets remaining for the holders of
notes or any assets may be insufficient to pay off the notes.


         CONTROL BY WELSH CARSON--THE INTERESTS OF WELSH CARSON MAY NOT BE
         ALIGNED WITH THE INTERESTS OF THE HOLDERS OF THE NOTES.

     Welsh Carson controls a majority of the voting power of the outstanding
common stock of Concentra and controls all of our affairs and policies.
Circumstances may occur in which the interests of Welsh Carson could be in
conflict with the interests of the holders of the notes. In addition, Welsh
Carson may have an interest in pursuing acquisitions, divestitures or other
transactions that, in their judgment, could enhance their equity investment,
even though such transactions might involve risks to the holders of the notes.
See "Management" and "Certain Relationships and Related Transactions."


         FINANCING CHANGE OF CONTROL OFFER--WE MAY NOT HAVE THE ABILITY TO RAISE
         THE FUNDS NECESSARY TO FINANCE THE CHANGE OF CONTROL OFFER REQUIRED BY
         THE INDENTURE.

     Upon the occurrence of certain specific kinds of change of control events,
we will be required to offer to repurchase all outstanding notes. However, it is
possible that we will not have sufficient funds at the time of the change of
control to make the required repurchase of notes or that restrictions in the
senior credit facilities will not allow such repurchases. In addition, certain
corporate events, such as a leveraged recapitalization that would increase the
level of our indebtedness, would not necessarily constitute a "change of
control" under the indenture. See "Description of Notes--Repurchase at the
Option of Holders."


         FRAUDULENT CONVEYANCE MATTERS--FEDERAL AND STATE STATUTES ALLOW COURTS,
         UNDER SPECIFIC CIRCUMSTANCES, TO CANCEL THE NOTES, VOID GUARANTEES OR
         SUBORDINATE CLAIMS IN RESPECT OF THE NOTES.

     As described in this prospectus, the net proceeds from the sale of the
notes were distributed to Concentra to partially finance the merger. Under
applicable provisions of the Federal Bankruptcy Code or comparable provisions of
state fraudulent transfer or conveyance law, if we or our subsidiary guarantors
at the time the notes or the guarantees were issued, as the case may be,


                                       19
<PAGE>


     (a)  incurred those obligations with the intent to hinder, delay or defraud
          creditors, or

     (b)  o received less than reasonably equivalent value or fair consideration
            for incurring those obligations and

          o either

               (A)  was insolvent at the time of the incurrence,

               (B)  was rendered insolvent by reason of that incurrence and the
                    application of the proceeds received from that incurrence,

               (C)  was engaged or was about to engage in a business or
                    transaction for which the assets remaining with it
                    constituted unreasonably small capital to carry on its
                    business, or

               (D)  intended to incur, or believed that it would incur, debts
                    beyond its ability to pay those debts as they mature,

then, in each of those cases, a court could avoid, in whole or in part, the
notes or the guarantees, as the case may be. A court may also subordinate the
notes or guarantees to our existing and future indebtedness or that of the
subsidiary guarantors. The avoidance or subordination of all or part of the
notes or guarantees could result in an event of default with respect to other
indebtedness of Concentra Operating, Concentra or the subsidiary guarantors
which could result in acceleration of that indebtedness.

     The measure of insolvency for purposes of the foregoing will vary depending
upon the law applied in that case. Generally, a company would be considered
insolvent if the sum of its debts, including contingent liabilities, was greater
than all of its assets at a fair valuation or if the present fair saleable value
of its assets was less than the amount that would be required to pay the
probable liability on its existing debts, including contingent liabilities, as
they become absolute and matured.


         NO PRIOR MARKET FOR NOTES--YOU CANNOT BE SURE THAT AN ACTIVE TRADING
         MARKET WILL DEVELOP FOR THESE NOTES.

     Prior to the offering, there was no public market for the notes. We have
been informed by the initial purchasers that they are making a market in these
notes. However, the initial purchasers may cease their market-making at any
time. In addition, the liquidity of the trading market in the notes, and the
market price quoted for the notes, may be adversely affected by changes in the
overall market for high yield securities and by changes in our financial
performance or prospects or in the prospects for companies in our industry
generally. As a result, you cannot be sure that an active trading market will
develop for the notes.


         OLD NOTES WILL NOT BE REGISTERED UNDER THE SECURITIES ACT--IF YOU DO
         NOT EXCHANGE YOUR OLD NOTES FOR NEW NOTES, YOUR OLD NOTES MAY TRADE AT
         DISCOUNT BECAUSE YOU MAY NOT BE ABLE TO TRANSFER SUCH NOTES.

     In the event the exchange offer is completed, we will not be required to
register the old notes under the Securities Act. In such event, the new notes
would rank equally with the old notes. Holders of old notes seeking liquidity in
their investment would have to rely on exemptions from registration requirements
under the securities laws, including the Securities Act. A reduction of the
aggregate principal amount of the old notes as a result of the completion of the
exchange offer may have an adverse effect on the ability of holders of the old
notes to transfer such notes.


RISKS APPLICABLE TO THE BUSINESS

         RISKS OF FUTURE ACQUISITIONS AND JOINT VENTURES--OUR ABILITY TO MAKE
         FUTURE ACQUISITIONS, ENTER INTO JOINT VENTURES AND TO INTEGRATE THOSE
         OPERATIONS COULD AFFECT OUR GROWTH AND OPERATIONS.

     We are in various stages of negotiations to acquire businesses and
occupational healthcare centers from a number of possible selling groups or to
enter into joint ventures to operate occupational healthcare centers. We cannot


                                       20
<PAGE>


assure you that further suitable acquisition or joint venture candidates can be
found, that acquisitions or joint ventures can be financed or consummated on
favorable terms or that such acquisitions or joint ventures, if completed, will
be successful. In addition, we cannot assure you we will be able to successfully
integrate the operations of any acquired business or joint venture or institute
company-wide systems and procedures to successfully operate the combined
enterprises. The success of our acquisitions and joint ventures will be
determined by numerous factors, including:

     o  our ability to identify suitable acquisition or joint venture
        candidates;

     o  competition for such acquisitions or joint ventures;

     o  the purchase price;

     o  the financial performance of the acquired businesses or joint ventures
        after acquisition; and

     o  our ability to integrate effectively the operations of acquired
        businesses or joint ventures into our operations.

     A strategy of growth by acquisition or joint venture also involves the risk
of assuming unknown or contingent liabilities of the acquired business or joint
venture, which could be material, individually or in the aggregate.


         MANAGEMENT OF GROWTH--OUR CONTINUED RAPID GROWTH COULD PLACE A
         SIGNIFICANT STRAIN ON OUR MANAGEMENT AND OTHER RESOURCES.

     We have experienced rapid growth. Our recent and continued rapid growth
could place a significant strain on our management and other resources. We
anticipate that any continued growth will require us to continue to recruit,
hire, train and retain a substantial number of new and highly skilled
administrative, information technology, finance, sales and marketing and support
personnel. Our ability to compete effectively and to manage current and any
future growth will depend on our ability to continue to implement and improve
operational, financial and management information systems on a timely basis and
to expand, train, motivate and manage our workforce. Should we continue to
experience rapid growth, we cannot assure you that personnel, systems,
procedures and controls will be adequate to support our operations or that
management will adequately anticipate all demands that growth will place on us.


          COMPETITION--INCREASED COMPETITION COULD ADVERSELY AFFECT OUR GROWTH
          AND OPERATIONS.

     The market to provide occupational healthcare services is highly fragmented
and competitive. Our primary competitors have typically been independent
physicians, hospital emergency departments and hospital-owned or
hospital-affiliated medical facilities.

     We believe that, as managed care techniques continue to gain acceptance in
the occupational healthcare marketplace, our competitors will increasingly
consist of nationally focused workers' compensation managed care service
companies, specialized provider groups, insurance companies, health management
organizations and other significant providers of managed care products.
Legislative reforms in some states permit employers to designate health plans
such as health management organizations and preferred provider organizations to
cover workers' compensation claimants. Because many health plans have the
ability to manage medical costs for workers' compensation claimants, that
legislation may intensify competition in the market we serve. Many of our
current and potential competitors are significantly larger and have greater
financial and marketing resources than ours, and there can be no assurance that
we will continue to maintain our existing performance or be successful with any
new products or in any new geographic markets we may enter.


         UNCERTAINTIES RELATED TO CHANGING HEALTHCARE ENVIRONMENT; CHANGES IN
         MARKET DYNAMICS--CHANGES IN THE HEALTHCARE ENVIRONMENT AND MARKET
         DYNAMICS COULD ADVERSELY AFFECT OUR GROWTH AND OPERATIONS.

     We cannot assure you that state fee schedule changes will not adversely
affect us, that we will prosper in the changing healthcare environment or that
our strategy to develop managed care programs will succeed in meeting


                                       21
<PAGE>


employers' and workers' occupational healthcare needs. The healthcare industry
has experienced substantial changes in recent years. Although managed care has
yet to become a major factor in occupational healthcare, we anticipate that
managed care programs may play an increasing role in the delivery of
occupational healthcare services, and that competition in the occupational
healthcare industry may shift from individual practitioners to specialized
provider groups such as those managed by us, insurance companies, health
management organizations and other significant providers of managed care
products.


         UNCERTAINTIES REGARDING HEALTHCARE REFORM--HEALTHCARE REFORM MAY
         INTENSIFY COMPETITION AND REDUCE THE COSTS OF WORKERS' COMPENSATION
         CLAIMS WHICH COULD ADVERSELY AFFECT OUR BUSINESS AND RESULTS OF
         OPERATIONS.

     Legislative reforms in some states permit employers to designate health
plans such as health management organizations and preferred provider
organizations to cover workers' compensation claimants. Because many health
plans have the capacity to manage healthcare for workers' compensation
claimants, that legislation may intensify competition in the market we serve.
Within the past few years, several states have experienced decreases in the
number of workers' compensation claims and the total value of claims which have
been reflected in workers' compensation insurance premium rate reductions in
those states. We believe that declines in workers' compensation costs in these
states are due principally to intensified efforts by payors to manage and
control claim costs, to improved risk management by employers and to legislative
reforms. If declines in workers' compensation costs occur in many states and
persist over the long-term, they may have an adverse impact on our business,
financial condition and results of operations.


         RISKS INHERENT IN PROVISION OF MEDICAL SERVICES; POSSIBLE LITIGATION
         AND LEGAL LIABILITY--SUITS AGAINST US MAY LEAD TO SIGNIFICANT
         LIABILITIES.

     Our affiliated physician associations and some of our employees are
involved in the delivery of healthcare services to the public and, therefore,
are exposed to the risk of professional liability claims. Claims of this nature,
if successful, could result in substantial damage awards to the claimants which
may exceed the limits of any applicable insurance coverage. We are indemnified
under our management agreements with our affiliated physician associations from
claims against them, maintain liability insurance for ourselves and negotiate
liability insurance for the physicians in our affiliated physician associations.
However, successful malpractice claims asserted against us or our affiliated
physician associations could have a material adverse effect on our business,
financial condition and results of operations. Further, new types of lawsuits
against managed care companies as well as against employers who use managed care
in workers' compensation cases have been proposed which, if established and
successful, may discourage the use of managed care in workers' compensation
cases and could have an adverse affect on our business, financial condition and
results of operations.

     Through our specialized cost containment and field case management
services, we make recommendations about the appropriateness of providers'
proposed medical treatment plans of patients throughout the country, and as a
result we could be subject to charges arising from any adverse medical
consequences. We do not grant or deny claims for payment of benefits and we do
not believe that we engage in the practice of medicine or the delivery of
medical services. We cannot assure you, however, that we will not be subject to
claims or litigation related to the grant or denial of claims for payment of
benefits or allegations that we engage in the practice of medicine or the
delivery of medical services. In addition, we cannot assure you that we will not
be subject to other litigation that may adversely affect our business, financial
condition and results of operations. We maintain errors and omissions insurance
and such other lines of coverage as we believe are reasonable in light of our
experience to date. We cannot assure you, however, that our insurance will be
sufficient or that insurance will be available at reasonable cost to protect us
from liability which might adversely affect our business, financial condition
and results of operations.


         CORPORATE PRACTICE OF MEDICINE AND OTHER LAWS AND REGULATIONS--THESE
         LAWS AND REGULATIONS MAY INCREASE OUR COSTS WHICH WOULD ADVERSELY
         AFFECT OUR ABILITY TO COMPETE.

     State laws relating to our business vary widely from state to state and are
seldom interpreted by courts or regulatory agencies in a way that provides
guidance with respect to our business operations. In addition, many states


                                       22
<PAGE>


have licensing or regulatory programs and our business may be adversely affected
by failure to comply with existing laws and regulations, failure to obtain
necessary licenses and government approvals or failure to adapt to new or
modified regulatory requirements.

     Most states limit the practice of medicine to licensed individuals or
professional organizations comprised of licensed individuals. Many states also
limit the scope of business relationships between business entities like us and
licensed professionals and professional corporations, particularly with respect
to fee-splitting between a physician and another person or entity and
non-physicians exercising control over physicians engaged in the practice of
medicine.

     Laws and regulations relating to the practice of medicine, fee-splitting
and similar issues vary widely from state to state, are often vague, and are
seldom interpreted by courts or regulatory agencies in a manner that provides
guidance with respect to business operations such as ours. Although we attempt
to structure all of our operations so that they comply with the relevant state
statutes and applicable medical practice, fee-splitting and similar laws, we
cannot give any assurances that:

     o  courts or governmental officials with the power to interpret or enforce
        these laws and regulations will not assert that we or certain
        transactions in which we are involved are in violation of such laws and
        regulations; or

     o  future interpretations of such laws and regulations will not require
        structural and organizational modifications of our business.

     Many states, including a number of those in which we transact business,
have licensing and other regulatory requirements applicable to our business.
Approximately half of the states have enacted laws that require licensing of
businesses, such as ours, which provide medical review services. Some of these
laws apply to medical review of care covered by workers' compensation. These
laws typically establish minimum standards for qualifications of personnel,
confidentiality, internal quality control and dispute resolution procedures.
These regulatory programs may result in increased costs of operation for us,
which may have an adverse impact on our ability to compete with other available
alternatives for healthcare cost control. In addition, new laws regulating the
operation of managed care provider networks have been adopted by a number of
states.

     These laws may apply to managed care provider networks having contracts
with us or to provider networks which we have organized and may organize in the
future. To the extent we are governed by these regulations, we may be subject to
additional licensing requirements, financial oversight and procedural standards
for beneficiaries and providers. Regulation in the healthcare and workers'
compensation fields is constantly evolving. We are unable to predict what any
additional government regulations affecting our business may be promulgated in
the future.

     In addition, the automobile insurance industry, like the workers'
compensation industry, is regulated on a state-by-state basis. Although
regulatory approval is not required for us to offer most of our services to the
automobile insurance market, state regulatory approval is required in order to
offer automobile insurers' products that permit them to direct claimants into a
network of medical providers.


          FRAUD AND ABUSE LAWS--CHANGES IN FRAUD AND ABUSE LAWS MAY LEAD TO
          SIGNIFICANT LIABILITIES.

     A federal law, the Anti-Kickback Statute, prohibits the offer, payment,
solicitation or receipt of any form of remuneration to induce or in return for
the referral of Medicare or other governmental health program patients or
patient care opportunities, or in return for the purchase, lease or order of
items or services that are covered by Medicare or other governmental health
programs. Violations of the statute can result in the imposition of substantial
civil and criminal penalties. In addition, as of January 1, 1995, certain
statutory anti-referral provisions, known as the Stark Amendments, prohibit a
physician with a "financial relationship" with an entity from referring a
patient to that entity for the provision of any of eleven "designated health
services," some of which are provided by physician associations affiliated with
us.


                                       23
<PAGE>


     At least seven of the states where we conduct our healthcare services
business--Arizona, California, Florida, Illinois, Maryland, New Jersey and
Texas--have enacted statutes similar in scope and purpose to the Anti-Kickback
Statute, which are applicable to services other than those covered by Medicare
or other governmental health programs. In addition, most states have statutes,
regulations or professional codes that restrict a physician from accepting
various kinds of remuneration in exchange for making referrals. Several states
are considering legislation that would prohibit referrals by a physician to an
entity in which the physician has a specified financial interest. Even in states
that have not enacted that kind of statute, we believe that regulatory
authorities and state courts interpreting these statutes may regard federal law
under the Anti-Kickback Statute as persuasive.

     We believe that our arrangements with our affiliated physician associations
should not violate the Anti-Kickback Statute, the Stark Amendments and
applicable state laws. However, all of these laws are subject to modification
and interpretation and have not often been interpreted by appropriate
authorities in a manner that provides guidance to our business. Moreover these
laws are enforced by authorities vested with broad discretion. We have attempted
to structure all of our operations so that they should not violate any
applicable anti-kickback and anti-referral prohibitions.

     We also continually monitor developments in this area. If these laws are
interpreted in a manner contrary to our interpretation, are reinterpreted or
amended, or if new legislation is enacted with respect to healthcare fraud and
abuse or similar issues, we will seek to restructure any affected operations so
as to maintain compliance with applicable law. We cannot assure you that a
restructuring will be possible, or, if possible, that it will not adversely
affect our business, financial condition and results of operations.


         RELIANCE ON DATA PROCESSING AND LICENSED SOFTWARE--INTERRUPTION OF DATA
         PROCESSING OR THE REVOCATION OF A LICENSE TO USE SOFTWARE COULD
         ADVERSELY AFFECT OUR BUSINESS AND RESULTS OF OPERATIONS.

     Certain aspects of our business are dependent upon our ability to store,
retrieve, process and manage data and to maintain and upgrade our data
processing capabilities. Interruption of data processing capabilities for any
extended length of time, loss of stored data, programming errors or other
computer problem could have a material adverse affect on our business and
results of operations. Certain of the software that we used in our medical bill
review operation is licensed from an independent third party software company
under a nonexclusive license that may be terminated by either party upon 90 days
notice. While we have historically maintained a good relationship with the
licensor, we cannot assure you that this software license will not be terminated
or that the licensor will be able to continue the license on its existing terms.
We are currently negotiating an extension of this software license. Although we
believe that alternative software would be available if the existing license
were terminated, termination could be disruptive and could have a material
adverse effect on our business, financial condition and results of operations.
See "Business-Information Systems and Technology."


          YEAR 2000 ISSUE--WE COULD BE ADVERSELY AFFECTED IF OUR YEAR 2000
          PROBLEMS ARE SIGNIFICANT.

     The Year 2000 issue generally refers to the problems that some software may
have in determining the correct century for the year. For example, software with
date-sensitive functions that is not Year 2000 compliant may not be able to
distinguish whether "00" means 1900 or 2000, which may result in failures or the
creation of erroneous results. Currently, many computer systems and software
products are coded to accept only two-digit entries in the date code field.
These date code fields will need to accept four digit entries to distinguish
between dates before and after January 1, 2000. As a result, many companies'
software and computer systems may need to be upgraded or replaced in order to
comply with these Year 2000 requirements. If we, or third parties with which we
do business, fail to make each of our software systems Year 2000 compliant in a
timely manner, we could be materially adversely impacted. "Management's
Discussion and Analysis of Financial Condition and Results of
Operations-Information Systems-Year 2000" and "Business-Information Systems and
Technology."


          DEPENDENCE UPON KEY PERSONNEL--A LOSS OF KEY PERSONNEL COULD ADVERSELY
          AFFECT US.

     Our success depends in large part on the services of our senior management
team. The loss of any of our key executives could materially adversely affect us
and seriously impair our ability to implement our strategy. Our abil-


                                       24
<PAGE>


ity to manage our anticipated growth will depend on our ability to identify,
hire and retain additional qualified management personnel. We may be
unsuccessful in attracting and retaining personnel and that failure could
materially adversely affect our business, financial condition and results of
operations. See "Management."

                      THE TRANSACTIONS AND USE OF PROCEEDS

     The following is a summary of the structure of, and conditions to the
completion of, the merger and related transactions. This summary is not
complete. For a more complete understanding of the terms of the merger, you
should read the merger agreement, a copy of which has been filed with the
Commission.


STRUCTURE OF THE MERGER

     Under the merger agreement Yankee merged with and into Concentra and
Concentra was the surviving corporation in the merger. At the effective time of
the merger:

     o  the stockholders of Concentra, including option holders, received an
        aggregate of $694.6 million in cash, without interest, for the shares of
        Concentra common stock, other than shares held by Yankee, and "in the
        money" stock options that they own. Shares held by Concentra, its
        subsidiaries, Yankee or its affiliates were cancelled in the merger; and

     o  each outstanding share of common stock of Yankee was converted into one
        share of common stock of the same class of Concentra the surviving
        corporation in the merger.

     As a result of the merger, the Concentra common stock ceased to be publicly
traded. The surviving corporation in the merger continues to operate under the
name "Concentra Managed Care, Inc." Immediately after the merger, Concentra
transferred all of its existing assets, including the shares of its
subsidiaries, to Concentra Operating.

     As a result of the merger, the Welsh Carson investors acquired an ownership
interest of approximately 86% in Concentra and Ferrer Freeman acquired an
ownership interest of approximately 7% in Concentra. The remaining approximate
7% interest is owned by the other investors. The merger was accounted for as a
recapitalization in which the historical basis of our assets and liabilities was
not affected and no new goodwill related to the merger was created.


FINANCING OF THE MERGER

     A total of approximately $1.2 billion was required to:

     o  pay the cash consideration to Concentra stockholders in the merger;

     o  repay indebtedness, including the purchase of Concentra's outstanding
        convertible subordinated notes; and

     o  pay related fees and expenses.

See "Prospectus Summary--The Transactions-Sources and Uses of Funds."

     The sources of funding for the transactions were:

     o  drawings under the senior credit facilities;

     o  net proceeds from the issuance of the discount debentures;

     o  proceeds from the equity contributions; and

     o  net proceeds from the offering of the old notes.


                                       25
<PAGE>


DEBT TENDER OFFERS

     In connection with the merger, Concentra conducted debt tender offers to
acquire all of its outstanding convertible subordinated notes and to eliminate
the interest expense associated with those notes. Concentra bought all but
$190,000 of the 6.0% convertible subordinated notes and bought all but $100,000
of the 4.5% convertible subordinated notes. We completed an offer to repurchase
the outstanding 6.0% convertible subordinated notes and 4.5% convertible
subordinated notes not previously tendered and accepted for payment at $1,000
per $1,000 principal amount plus accrued and unpaid interest. In that offer,
Concentra bought all of the remaining 4.5% convertible subordinated notes and
bought all but $13,000 of the 6.0% convertible subordinated notes. The indenture
governing the notes will permit us to distribute funds to Concentra to pay
interest, principal, any premium and any amounts due upon conversion of the
remaining $13,000 of 6.0% convertible subordinated notes.

                               THE EXCHANGE OFFER

PURPOSE OF THE EXCHANGE OFFER

     The holders of the old notes are currently entitled to registration rights
under a registration rights agreement. Pursuant to the registration rights
agreement, we became obligated to file with the Commission a registration
statement covering the offer by us to the holders of the old notes to exchange
all of the old notes for the new notes. This exchange offer, if completed, will
satisfy our obligations under the registration rights agreement.


TERMS OF THE EXCHANGE OFFER

     Upon the terms and subject to the conditions set forth in this prospectus
and in the accompanying letter of transmittal, we will accept all notes properly
tendered and not withdrawn prior to 5:00 p.m., New York City time, on the
expiration date. We will issue $1,000 principal amount of new notes in exchange
for each $1,000 principal amount of old notes accepted in the exchange offer.
Holders may tender some or all of their notes under the exchange offer.

     Based on an interpretation by the staff of the Commission set forth in
no-action letters issued to third parties, we believe that the new notes issued
pursuant to the exchange offer in exchange for old notes may be offered for
resale, resold and otherwise transferred by the holders other than any such
holder that is our "affiliate" within the meaning of the Securities Act or such
holder that is a broker-dealer, without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such new
notes are acquired in the ordinary course of such holders' business, and such
holders have no arrangement with any person to participate in the distribution
of such new notes. See Morgan Stanley & Co., Inc., Commission No-Action Letter
(available June 5, 1991), Exxon Capital Holdings Corporation, Commission
No-Action Letter (available May 13, 1988), and Shearman & Sterling, Commission
No-Action Letter (available July 2, 1993).

     If you were to be participating in the exchange offer for the purposes of
distributing securities in a manner not permitted by the Commission's
interpretation, you could not rely on the position of the staff of the
Commission in Exxon Capital Holdings Corporation or similar interpretive letters
and could not resell your notes unless an exemption from the registration
provisions of the Securities Act is available for the transfer or you resell
your notes in compliance with the registration and prospectus delivery
requirements of the Securities Act.

     Each broker-dealer that is issued new notes in the exchange offer for its
own account which were acquired by the broker-dealer as a result of
market-making activities or other trading activities, must acknowledge that it
will deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of new notes. The letter of transmittal states that
by so acknowledging and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act. This prospectus, as it may be amended or supplemented from time to time,
may be used by a broker-dealer in connection with resales of new notes. See
"Plan of Distribution."

     Except as described above, this prospectus may not be used for an offer to
resell, resale or other transfer of new notes.


                                       26
<PAGE>


     The exchange offer is not being made to, nor will we accept tenders for
exchange from, holders of old notes in any jurisdiction in which the exchange
offer or the acceptance of it would not be in compliance with the securities or
blue sky laws of that jurisdiction.


TERMS OF THE EXCHANGE OFFER

     As of the date of this prospectus, there was $190.0 million aggregate
principal amount of the notes outstanding. This prospectus, together with the
letter of transmittal, is being sent to all registered holders of old notes as
of the date of this prospectus.

     We will be deemed to have accepted validly tendered notes when, as and if
we have given written notice of acceptance to the exchange agent. The exchange
agent will act as agent for the tendering holders of old notes for the purposes
of receiving the new notes from us and delivering new notes to the tendering
holders.

     If old notes are not tendered, they will remain outstanding and will
continue to accrue interest from their date of issue, August 17, 1999, at a rate
of 13% per annum.

     Except as noted below, in the event the exchange offer is consummated, we
will not be required to register the old notes that are not tendered. In that
event, holders of notes seeking liquidity in their investment would have to rely
on exemptions to registration requirements under the securities laws, including
the Securities Act. See "Risk Factors--Risks Applicable to the Notes." Pursuant
to the registration rights agreement, we are required to file a shelf
registration statement with the Commission if a holder of notes notifies us that
such holder is not allowed to participate in this exchange offer by law.


EXPIRATION DATE; EXTENSIONS

     The term "expiration date" means the expiration date on the cover page of
this prospectus, unless we, in our discretion, extend the exchange offer, in
which case the term "expiration date" means the latest date to which the
exchange offer is extended.

     In order to extend the expiration date, we will notify the exchange agent
of any extension by written notice and will make a public announcement of that
extension, each prior to 9:00 a.m., New York City time, on the next business day
after the previously scheduled expiration date. The announcement may state that
we are extending the exchange offer for a specified period of time.


PROCEDURES FOR TENDERING

     Unless the tender is being made in book-entry form, to tender in the
exchange offer, a holder must complete, sign and date the letter of transmittal,
or a facsimile of it,

     o  have the signatures guaranteed if required by the letter of transmittal;
        and

     o  mail or otherwise deliver the letter of transmittal or the facsimile,
        the old notes and any other required documents, to the exchange agent
        prior to 5:00 p.m., New York City time, on the expiration date.

     The Depository Trust Company is commonly referred to as the DTC. Any
financial institution that is a participant in The Depository Trust Company's
system may make book-entry delivery of the old notes by causing DTC to transfer
the old notes into the exchange agent's account. In connection with the delivery
of old notes through book-entry transfer into the exchange agent's account at
DTC, the letter of transmittal, or facsimile, with any required signature
guarantees and any other required documents or an agent's message, as described
below, must be transmitted to and received or confirmed by the exchange agent at
its addresses set forth under the caption "Exchange Agent," below, prior to 5:00
p.m., New York City time, on the expiration date. Delivery of documents to DTC
in accordance with its procedures does not constitute delivery to the exchange
agent.


                                       27
<PAGE>


     To effectively tender notes through DTC, the financial institution that is
a participant in DTC will electronically transmit its acceptance through the
Automatic Tender Offer Program. DTC will then edit and verify the acceptance and
send an agent's message to the exchange agent for its acceptance. The term
"agent's message" means a message transmitted by DTC, received by the exchange
agent and forming part of the book-entry confirmation, which states that DTC has
received an express acknowledgment from a participant in DTC that is tendering
old notes that are the subject of that book-entry confirmation; that the
participant has received and agrees to be bound by the terms of the applicable
letter of transmittal; and that we may enforce that agreement against that
participant. The exchange agent will make a request to establish an account for
the notes of DTC for the purposes of the exchange offer promptly after the date
of this prospectus.

     The method of delivery of old notes and the letter of transmittal and all
other required documents to the exchange agent is at the election and risk of
the holders. Instead of delivery by mail, we recommend that holders use an
overnight or hand delivery service. In all cases, holders should allow
sufficient time to assure delivery to the exchange agent before the expiration
date. No letter of transmittal of old notes should be sent to us. Holders may
request their respective brokers, dealers, commercial banks, trust companies or
nominees to effect the tenders for those holders.

     Any beneficial owner whose old notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered holder promptly and instruct that
registered holder to tender on behalf of the beneficial owner. If the beneficial
owner wishes to tender on that owner's own behalf, the owner must, prior to
completing and executing the letter of transmittal and delivery of such owner's
old notes, either make appropriate arrangements to register ownership of the old
notes in the owner's name or obtain a properly completed bond power from the
registered holder. The transfer of registered ownership may take considerable
time.

     Signature on a letter of transmittal or a notice of withdrawal, must be
guaranteed, unless the old notes tendered pursuant thereto are tendered:

     o  by a registered holder who has not completed the box entitled "Special
        Issuance Instructions" or "Special Delivery Instructions" on the letter
        of transmittal; or

     o  for the account of an eligible institution, as described below.

     In the event that signatures on a letter of transmittal or a notice of
withdrawal, are required to be guaranteed, that guarantee must be by an eligible
institution.

     An "eligible institution" is a member firm of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.,
a commercial bank or trust company having an office or correspondent in the
United States or an eligible guarantor institution within the meaning of the
Exchange Act, which is a member of the Securities Transfer Agents Medallion
Program or the Stock Exchange Medallion Signature Program.

     If the letter of transmittal is signed by a person other than the
registered holder of any old notes, the old notes must be endorsed by the
registered holder or accompanied by a properly completed bond power signed by
the registered holder.

     If the letter of transmittal or bond powers are signed or endorsed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, those
persons should so indicate when signing, and unless waived by us, submit
evidence satisfactory to us of their authority to act in that capacity with the
letter of transmittal.

GUARANTEED DELIVERY PROCEDURES

     If you desire to accept the exchange offer, and

     o  certificates for the old notes are not immediately available;

     o  time will not permit a letter of transmittal or notes to reach the
        exchange agent before the expiration date; or

     o  the procedure for book-entry transfer cannot be completed on a timely
        basis;

a tender may be effected if the exchange agent has received at its addresses set
forth under the caption "Exchange Agent" below prior to 5:00 p.m., New York City
time, on the expiration date from an eligible institution a properly completed
and duly executed notice of guaranteed delivery, substantially in the form
provided by us, setting forth:

     o  the name and address of the registered holder;

     o  the certificate numbers of the old notes;

     o  the principal amount of the notes to be tendered;

     o  stating that the tender is being made by the notice of guaranteed
        delivery; and

     o  guaranteeing that within five New York Stock Exchange trading days after
        the expiration date, the old notes, in proper form for transfer, or a
        confirmation of book-entry transfer of the notes into the exchange
        agent's account at DTC, will be delivered by that eligible institution
        together with a properly completed and duly executed letter of
        transmittal, and any other required documents, or, if applicable, an
        agent's message instead of the letter of transmittal.

     Unless old notes being tendered by the above-described method are deposited
with the exchange agent within the time period set forth above, accompanied or
preceded by a properly completed letter of transmittal and any other required
documents or, if applicable, an agent's message instead of the letter of
transmittal, we may, at our option, reject the tender.


ACCEPTANCE OF OLD NOTES FOR EXCHANGE

     The tender by a holder of old notes will constitute an agreement between us
and the holder in accordance with the terms and subject to the conditions in
this prospectus and in the letter of transmittal.

     All questions as to the validity, form, eligibility, including time of
receipt and acceptance for exchange of any tender of old notes will be
determined by us, which determination will be final and binding. We reserve the
absolute right to reject any or all tenders not in proper form or the acceptance
for exchange of which may, in the opinion of our counsel, be unlawful. We also
reserve the absolute right to waive any defect or irregularity in the tender of
any old notes. In addition, we reserve the right to waive any of the conditions
of the exchange offer in our reasonable discretion.

     Our interpretation of the terms and conditions of the exchange offer,
including the instructions in the letter of transmittal, will be final and
binding, on all parties. Unless waived, any defects or irregularities in
connection with tenders of old notes must be cured within a time period we will
determine. Although we intend to request the exchange agent to notify holders of
defects or irregularities relating to tenders of old notes, neither we, the
exchange agent nor any other person will have any duty or incur any liability
for failure to give that notification. Tenders of old notes will not be
considered to have been made until those defects or irregularities have been
cured or waived. Any old notes received by the exchange agent that are not
properly tendered and as to which the defects or irregularities have not been
cured or waived will be returned by the exchange agent to the tendering holders,
unless otherwise provided in the letter of transmittal, as soon as practicable
following the expiration date.


                                       29
<PAGE>


     By tendering, you will represent to us that, among other things,

     o  the new notes acquired pursuant to the exchange offer are being obtained
        in the ordinary course of your business;

     o  you have no arrangement with any person to participate in the
        distribution of those new notes;

     o  you are not an "affiliate," as defined under the Securities Act, of us;
        and

     o  if you are a broker or a dealer, as defined in the Exchange Act, that
        you acquired the old notes for your own account as a result of
        market-making activities or other trading activities and that you will
        comply with the registration and prospectus delivery requirements of the
        Securities Act.


WITHDRAWAL OF TENDERS

     Except as otherwise provided in this prospectus, tenders of old notes may
be withdrawn at any time prior to 5:00 p.m., New York City time, on the
expiration date.

     To withdraw a tender of notes in the exchange offer, a written transmission
notice of withdrawal via telegram, telex, facsimile transmission or letter must
be received by the exchange agent at its address set forth under the caption
"Exchange Agent" below prior to 5:00 p.m., New York City time, on the expiration
date. Any notice of withdrawal must:

     o  specify the name of the person having deposited the old notes to be
        withdrawn;

     o  identify the old notes to be withdrawn, including the certificate number
        or numbers and principal amount of those notes, or, in the case of old
        notes transferred by book-entry transfer, the name and number of the
        account at DTC to be credited;

     o  be signed by the person having deposited the old notes to be withdrawn
        in the same manner as the original signature on the letter of
        transmittal by which those notes were tendered, including any required
        signature guarantees, or be accompanied by documents of transfer
        sufficient to have the trustee with respect to the old notes register
        the transfer of such notes into the name of the person having made the
        original tender and withdrawing the tender; and

     o  specify the name in which any notes are to be registered, if different
        from that of the person having deposited the notes to be withdrawn.

     All questions as to the validity, form and eligibility, including time of
receipt, of withdrawal notices will be determined by us, which determination
shall be final and binding on all parties. Any old notes you withdraw will be
deemed not to have been validly tendered for purposes of the exchange offer, and
no new notes will be issued to you with respect to withdrawn old notes unless
the old notes so withdrawn are validly retendered. Any old notes that have been
tendered but that are not accepted for exchange will be returned to you as soon
as practicable after withdrawal, rejection of tender or termination of the
exchange offer. Properly withdrawn old notes may be retendered by following one
of the procedures described above under "Procedures for Tendering" at any time
prior to the expiration date.


CONDITIONS

     The exchange offer is not subject to any conditions other than that the
exchange offer does not violate applicable law or any applicable interpretation
of the staff of the Commission.


                                       30
<PAGE>


ACCOUNTING TREATMENT

     The new notes will be recorded at the same carrying value as the old notes
as reflected in our accounting records on the date of the exchange. Accordingly,
we will not recognize any gain or loss for accounting purposes upon the
completion of the exchange offer. Any expenses of the exchange offer that we
paid will be capitalized and amortized over the term of the new notes.

(1)  Concentra recorded the following non-recurring charges: (a) $38.6 million
     in the third quarter of 1997 primarily related to the formation of
     Concentra by the merger of CRA Managed Care, Inc. and OccuSystems, Inc.;

     (b) $12.6 million in the first quarter of 1998 primarily related to the
     merger with Preferred Payment Systems, Inc.; (c) $20.5 million in the
     fourth quarter of 1998 primarily related to the reorganization of the
     Managed Care Services division and charges related to the recognition of an
     impairment loss on the intangible related to an acquired contract; and (d)
     $54.4 million in the third quarter of 1999 primarily for fees, expenses and
     other non-recurring charges associated with the merger.

(2)  Prior to its recapitalization in March of 1994, CRA had elected to be taxed
     as an "S" corporation. In connection with its recapitalization, CRA was
     required to change from an "S" to a "C" corporation. This change resulted
     in CRA recording an incremental tax provision of $3.8 million in the first
     quarter of 1994. Concentra's pro forma net income for 1994 would have been
     $3.4 million higher had CRA been subject to federal and state income taxes
     during the entire period based upon an effective tax rate indicative of the
     statutory rate in effect during the period.

(3)  As a result of Concentra going private in the merger transaction, there are
     no longer publicly held shares outstanding and we believe that historical
     earnings per share information is not meaningful.

(4)  The ratio of earnings to fixed charges is computed by dividing the sum of
     net earnings, before deducting provisions for income taxes and fixed
     charges, and adjusted for the equity in earnings of unconsolidated
     subsidiaries and related distributions, by fixed charges. Fixed charges
     consist of interest on debt, including amortization of debt issuance costs,
     and one-fourth of rent expenses, estimated by management to be the interest
     component of such rentals.

(5)  The ratio of adjusted earnings to fixed charges is computed by dividing the

     one-fourth of rent expense, estimated by management to be the interest

RECAPITALIZATION TRANSACTION

     On March 2, 1999, Concentra announced that it had signed a definitive
merger agreement to merge with Yankee, a corporation formed by Welsh Carson, a
14.9% stockholder of Concentra. Concentra's board of directors unanimously
approved the transaction based upon the recommendation of its special committee
of the board of directors, which was formed on October 29, 1998 to evaluate
strategic alternatives in response to several unsolicited expressions of
interest regarding the possible acquisition of some or all of Concentra common
stock. On March 24, 1999, Concentra entered into an amended and restated
agreement and plan of merger with Yankee.

     On August 17, 1999, Concentra merged with Yankee. As a result of the
merger, each outstanding share of Concentra common stock was converted into the
right to receive $16.50 in cash. Welsh Carson acquired approximately 86%, funds
managed by Ferrer Freeman acquired approximately 7% and other investors acquired
approximately 7% of the post-merger shares of common stock of Concentra,
Concentra Operating's parent company, for $16.50 per share. Simultaneous with
the right to receive cash for shares, Yankee merged with and into Concentra and
Concentra contributed all of its operating assets and liabilities with the
exception of $110,000,000 of 14% Senior Discount Debentures due 2010 and
$327,750,000 of 6.0% and 4.5% Convertible Subordinated Notes to Concentra
Operating, a wholly-owned subsidiary of Concentra. The 6.0% and 4.5% Convertible
Subordinated Notes were substantially retired during the quarter as a result of
the Merger. The Merger was accounted for as a recapitalization transaction, with
no changes to the basis of assets or liabilities.


     The transaction was valued at approximately $1.2 billion, including the
refinancing of $327.8 million of the 6.0% and 4.5% convertible subordinated
notes that were tendered during the quarter. To finance the acquisition of
Concentra Welsh Carson, Ferrer Freeman and the other investors invested
approximately $423.7 million in equity financing, including the value of shares
already owned by Welsh Carson, and $110.0 million of 14% senior discount
debentures due 2010 with warrants issued by Concentra exercisable for its common
shares. Concentra Operating received from various lenders $375.0 million in term
loans, a $100.0 million revolving credit facility to replace the pre-merger
revolving credit facility and $190.0 million of 13% series A senior subordinated
notes due 2009. Concentra's excess cash balances funded merger and financing
related fees and expenses and related employee stock option exercises and
cancellation payments.

                                       34
<PAGE>

     Concentra incurred $18.0 million of deferred financing fees for the
issuance of the merger related financing and recorded a non-recurring charge of
$54.4 million in the third quarter of 1999 incurred primarily for fees, expenses
and other non-recurring charges associated with the merger. The utilization of
this non-recurring charge through September 30, 1999, was approximately $15.5
million for professional fees and services, $13.5 million for employee related
stock option exercises and cancellations, $10.5 million for a Welsh Carson
transaction fee, $5.5 million in non-cash charges for deferred compensation
expense related to the accelerated vesting and issuance of 210,000 shares of
restricted stock and $1.7 million of other non-recurring charges. At September
30, 1999, approximately $7.8 million of the non-recurring charge remains for
professional fees and services, employee related stock option exercises and
other non-recurring charges.


OVERVIEW

     Concentra 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. Following Concentra's merger
with Yankee, Concentra contributed all of its assets and shares in its
subsidiaries, including Concentra Health Services, Inc. and Concentra Managed
Care Services, Inc., to Concentra Operating, a wholly owned subsidiary of
Concentra.

     Throughout this prospectus, we refer to Concentra Health Services, Inc. as
Health Services and Concentra Managed Care Services, Inc. as Managed Care
Services. The following represents a discussion and analysis of the operations
of Concentra.

     Through Health Services we manage occupational healthcare centers at which
we provide support personnel, marketing, information systems and management
services to our affiliated physicians. Health Services, and the joint ventures
which Health Services controls, own all of the operating assets of our
occupational healthcare centers, including leasehold interests and medical
equipment. At our centers, we generate net patient service revenues primarily
from the diagnosis, treatment and management of work-related injuries and
illnesses and from other occupational healthcare services, such as
employment-related physical examinations, drug and alcohol testing, functional
capacity testing and other related programs. For the nine months ended September
30, 1998 and 1999, Health Services derived 63.2% and 63.7% of its net revenues
from the treatment of work-related injuries and illnesses, respectively, and
36.8% and 36.3% of its net revenues from non-injury related medical services,
respectively. For the years ended December 31, 1996, 1997 and 1998, Health
Services derived 63.8%, 63.5% and 63.1% of its net revenues from the treatment
of work-related injuries and illnesses, respectively and 36.2%, 36.5% and 36.9%
of its net revenues from non-injury related medical services, respectively.

     Physician and physical therapy services are provided at our centers under
management agreements with affiliated physician associations. These associations
or groups are organized professional corporations that hire licensed physicians
and physical therapists to provide medical services to our centers' patients.
Health Services has a nominee shareholder relationship with each group as
defined in EITF 97-2, "Application of APB Opinion No. 16 and FASB Statement No.
94 to Physician Practice Entities", and as a result, the financial statements of
each affiliated physician group are consolidated. Specifically:

     o  Health Services can at all times establish or effect change in the
        nominee shareholder;

     o  Health Services can cause a change in the nominee shareholer an
        unlimited number of times;

     o  Health Services has sole discretion without cause to establish or change
        the nominee shareholder;

     o  Health Services and each physician group would incur no more than a
        nominal cost to cause a change in the nominee shareholder; and

     o  neither Health Services nor the physician groups are subject to any
        significant adverse impact upon a change in the nominee shareholder.

     The management fees we collect from each physician group are calculated as
collected revenue net of compensation, benefits and other expenses incurred by
the groups.

                                       35
<PAGE>

     Through Managed Care Services we provide specialized cost containment and
field case management services designed to reduce costs associated with workers'
compensation, disability and automobile accident coverage. Managed Care Services
earns most of its revenues on a fee-for-service or percentage-of-savings basis.
The specialized cost containment services we provide include our:

     o  first-report-of-injury, utilization management, precertification and
        concurrent review;

     o  retrospective medical bill review;

     o  telephonic case management;

     o  preferred provider organizations, or preferred provider organization
        network access;

     o  independent medical examinations;

     o  peer reviews; and

     o  out-of-network bill review services.

     We have designed each service to reduce the cost of workers' compensation
claims, automobile accident injury claims and group health claims.

     On February 24, 1998, we merged Concentra Subsidiary, Inc. with Preferred
Payment Systems, Inc. in a pooling-of-interests transaction. This merger
significantly expanded our presence in the out-of-network group health bill
review market. Preferred Payment Systems, now operating as Concentra Preferred
Systems, Inc., is a nationwide provider of specialized cost containment and
outsourcing services for healthcare payors. In the first quarter of 1998, we
recorded a non-recurring charge of $12.6 million primarily associated with our
merger with Preferred Payment Systems. Managed Care Services has experienced
significant growth in its specialized cost containment services by virtue of the
acquisitions of:

     o  Focus Healthcare Management, Inc. on April 2, 1996;

     o  Prompt Associates, Inc. on October 29, 1996;

     o  First Notice Systems, Inc. on June 4, 1997;

     o  About Health, Inc. by Preferred Payment Systems in a two-step
        transaction on August 1, 1997 and October 31, 1997; and

     o  other smaller acquisitions.

     Our 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 their return to work. Our field case management
gross profit margins deteriorated in the second half of 1998 and we reorganized
field case management services in the fourth quarter of 1998. The reorganization
was designed to improve efficiency through facility consolidations and related
headcount reductions, and to recognize an impairment loss on the intangibles
related to an acquired contract and costs associated with settling claims on
other expired contracts. Due to our reorganization, we recorded a non-recurring
charge of $20.5 million. We believe that the current size of our field case
management office network is sufficient to serve the needs of our nationwide
customers. As a result, we anticipate opening only a few new field case
management offices per year if client needs in selected regions require it. We
would, however, examine the possibility of acquiring additional field case
management offices or businesses if an appropriate strategic opportunity were to
arise.

RESULTS OF OPERATIONS FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 1998
AND 1999

REVENUES

     Our total revenues increased 12.3% in the third quarter of 1999 to $176.7
million from $157.4 million in the third quarter of 1998. Health Services'
revenues increased 29.1% in the third quarter of 1999 to $89.9 million from
$69.6 million in the third quarter of 1998. Managed Care Services' revenues
decreased 1.1% in the third quarter of 1999 to $86.8 million as specialized cost
containment revenues increased 11.0% for the third quarter of 1999 to $50.7
million from $45.7 million in the third quarter of 1998 and field case
management revenues decreased 14.2% in the third quarter of 1999 to $36.1
million from $42.1 million in the third quarter of 1998.

     Our total revenues increased 10.2% for the nine months of 1999 to $506.2
million from $459.1 million for the nine months of 1998. Health Services'
revenues increased 25.2% for the nine months of 1999 to $242.4 million from
$193.7 million for the nine months of 1998. Managed Care Services' revenues
decreased 0.6% for the nine months of 1999 to $263.7 million as specialized cost
containment revenues increased 10.5% for the nine months of 1999 to $151.6
million from $137.2 million for the nine months of 1998 and field case
management revenues decreased 12.6% for the nine months of 1999 to $112.1
million from $128.3 million for the nine months of 1998.

     Health Services' revenue growth resulted primarily from the acquisition of
practices and an increase of business in existing markets.

     The increase in specialized cost containment revenue growth is largely
attributable to:

     o  our growth in out-of-network bill review services;

     o   preferred provider organization network access fees;

                                       37
<PAGE>

     o   first report of injury; and

     o   telephonic case management services in existing locations.

     The decrease in field case management revenue is primarily attributable to
a reorganization of the division in the fourth quarter of 1998 to improve
efficiency through facility consolidations and related headcount reductions and
the transition of the field case management business to a "task-based" approach
to providing services as opposed to the traditional hourly-billing rate oriented
"full" case management approach. This new approach to field case management
services has had the effect of causing a reduction in the billable hours per
case and has thereby contributed to our decrease in field case management
revenue. Although we anticipate further reductions in billable hours per case
associated with the continued transition to a "task-based" approach, we believe
further decreases in revenue may be somewhat mitigated or overcome by increases
in underlying case volume.

     Our total contractual allowances offset against revenues during the nine
months ended September 30, 1998 and 1999 were $12.2 million and $18.1 million,
respectively.


COST OF SERVICES

     Our total cost of services increased 17.1% in the third quarter of 1999 to
$139.0 million from $118.7 million in the third quarter of 1998. Health
Services' cost of sales increased 39.4% in the third quarter of 1999 to $71.4
million from $51.2 million in the third quarter of 1998 while Managed Care
Services' cost of services increased 0.2% in the third quarter of 1999 to $67.6
million from $67.5 million in the third quarter of 1998.

     Our total cost of services increased 13.8% for the nine months of 1999 to
$392.9 million from $345.2 million for the nine months of 1998. Health Services'
cost of sales increased 32.1% for the nine months of 1999 to $191.8 million from
$145.2 million for the nine months of 1998 while Managed Care Services' cost of
services increased 0.6% for the nine months of 1999 to $201.2 million from
$200.0 million for the nine months of 1998.

     Our total gross profit margin decreased to 21.3% in the third quarter of
1999 compared to 24.6% in the third quarter of 1998. Health Services, gross
profit margin decreased to 20.6% in the third quarter of 1999 compared to 26.4%
in the third quarter of 1998 while Managed Care Services' gross profit margin
decreased to 22.1% in the third quarter of 1999 compared to 23.1% in the third
quarter of 1998.

     Our total gross profit margin decreased to 22.4% for the first nine months
of 1999 compared to 24.8% for the first nine months of 1998. Health Services
gross profit margin decreased to 20.9% for the first nine months of 1999
compared to 25.0% for the first nine months of 1998 while Managed Care Services'
gross profit margin decreased to 23.7% for the first nine months of 1999
compared to 24.7% for the first nine months of 1998.

     Health Services' gross profit margin decreased primarily as a result of:

     o  lower same market rate and visit growth during the quarter and nine
        months ended September 30, 1999 than we have traditionally experienced;

     o  an acceleration in the roll-out of patient tracking and billing systems
        into the medical centers;

     o  increased spending on marketing and facility improvements; and

     o  the impact of lower margins from practices recently acquired and
        developed.

     The decrease in visit growth may be attributable to:

     o  decreases in national injury trends;

     o  weather; and

     o  other operational considerations attributable to the quarter.

                                       38
<PAGE>

     Health Services has also incurred start-up losses during the quarter of
approximately $1.9 million related to the newly established drug screening lab
in Memphis, TN and the acquisition of recently developed medical centers in
several new markets. Historically, as certain functions are consolidated and
other staff-related changes occur, coupled with increased patient volume, the
margins of acquired or developed practices have tended to improve.

     Managed Care Services' gross profit margins decreased in the third quarter
and first nine months of 1999 due primarily to a slowdown in field case
management revenue and a decrease in provider bill review and claims review
gross profit margins partially offset by an increase in specialized cost
containment services revenue which has historically had higher gross profit
margins than field case management.

     Provider bill review gross profit margins decreased due primarily to:

     o  pricing concessions made in the second half of 1998;

     o  a higher level of bad debt provision; and

     o  an increase in software maintenance fees associated with a third party
        software supplier.

     We expect the gross profit margin for provider bill review to continue to
be negatively affected for the remainder of 1999 versus 1998 due to the impact
of pricing concessions made in the second half of 1998 and due to an increase in
software maintenance fees associated with a third party software supplier.


GENERAL AND ADMINISTRATIVE EXPENSES

     General and administrative expenses increased 34.6% in the third quarter of
1999 to $16.0 million from $11.9 million in the third quarter of 1998, or 9.0%
and 7.5% as a percentage of revenue for the third quarter of 1999 and 1998,
respectively. General and administrative expenses increased 40.0% for the first
nine months of 1999 to $47.2 million from $33.7 million for the first nine
months of 1998, or 9.3% and 7.3% as a percentage of revenue for the first nine
months of 1999 and 1998, respectively. The increases in general and
administrative expenses in 1999 was due primarily to the continued investment in
the Information Services and Technology Group and in accounting and
administrative personnel.


AMORTIZATION OF INTANGIBLES

     Amortization of intangibles increased 62.9% in the third quarter of 1999 to
$3.3 million from $2.1 million in the third quarter of 1998, or 1.9% and 1.3% as
a percentage of revenue for the third quarter of 1999 and 1998, respectively.
Amortization of intangibles increased 55.6% for the nine months of 1999 to $9.5
million from $6.1 million for the nine months of 1998, or 1.9% and 1.3% as a
percentage of revenue for the nine months of 1999 and 1998, respectively. The
increase is primarily the result of a prospective change in the amortization
period of goodwill and the amortization of additional intangible assets such as
goodwill, customer lists and assembled workforces primarily associated with
acquisitions by Health Services.

     We have historically amortized goodwill over periods ranging from 30 to 40
years. Effective January 1, 1999, we changed our policy, on a prospective basis,
with respect to the amortization of goodwill. All existing and future goodwill
will be amortized over a period not to exceed 25 years. Had we adopted this
policy at the beginning of 1998, amortization for the three and nine months
ended September 30, 1998 and for the year ended December 31, 1998 would have
increased approximately $0.8 million, $2.4 million and $3.3 million,
respectively. As of September 30, 1999, net intangible assets consisted of the
following (amounts in thousands):

NON-RECURRING CHARGE

     In the first quarter of 1998, we recorded a non-recurring charge of $12.6
million primarily associated with the merger of Preferred Payment Systems. The
utilization of this charge through September 30, 1999, was approximately $5.3
million for professional fees and services, $2.6 million in costs associated
with personnel reductions, $1.1 million in facility consolidations and closings,
$1.6 million associated with the write-off of deferred financing fees on
Preferred Payment Systems indebtedness retired and $1.5 million of other
non-recurring costs. At September 30, 1999, approximately $0.5 million of the
non-recurring charge remains primarily related to remaining facility lease
obligations.

     In the fourth quarter of 1998, we recorded a non-recurring charge of $20.5
million primarily associated with the reorganization of our Managed Care
Services division to improve efficiency through facility consolidations and
related headcount reductions, an impairment loss on the intangible related to an
acquired contract and costs associated with settling claims on other expired
contracts. The use of this charge through September 30, 1999 was approximately
$7.4 million in charges related to an impairment loss on the intangible related
to an acquired contract, $3.9 million in costs associated with personnel
reductions, $0.4 million in costs associated with settling claims on other
expired contracts, $2.8 million in facility consolidations and $0.1 million of
other non-recurring costs. At September 30, 1999, approximately $5.9 million of
the non-recurring charge remains primarily related to remaining facility lease
obligations and costs associated with settling claims on other expired
contracts.

     In the third quarter of 1999, we recorded a non-recurring charge of $54.4
million primarily for fees, expenses and other non-recurring charges associated
with the merger. The utilization of this non-recurring charge through September
30, 1999, was approximately $15.5 million for professional fees and services,
$13.5 million for employee related stock option exercises and cancellations,
$10.5 million for a Welsh Carson transaction fee, $5.5 million in non-cash
charges for deferred compensation expense related to the accelerated vesting and
issuance of 210,000 shares of restricted stock and $1.7 million of other
non-recurring charges. At September 30, 1999, approximately $7.8 million of the
non-recurring charge remains for professional fees and services, employee
related stock option excercises and other non-recurring charges.


INTEREST EXPENSE

     Interest expense increased $5.6 million in the third quarter of 1999 to
$10.2 million from $4.7 million in the third quarter of 1998 and increased $6.5
million for the first nine months of 1999 to $19.6 million from $13.1 million in
the first nine months of 1998 due primarily to increased outstanding borrowings
from the issuance of $565.0 million in merger related financing with annual
interest rates ranging from 8.5% to 13.0% offset by the retirement of
substantially all of the $327.8 million of the 6.0% and 4.5% convertible
subordinated notes.


INTEREST INCOME

     Interest income decreased $0.7 million in the third quarter of 1999 to $0.6
million from $1.3 million in the third quarter of 1998 and decreased $0.2
million for the first nine months of 1999 to $2.7 million from $2.9 million for
the first nine months of 1998 primarily as a result of excess cash being used to
complete the merger transaction and to pay related fees and expenses. The $0.2
million decrease in interest income for the first nine months of 1999 versus the
first nine months of 1998 is partially offset by the increase in our investment
of excess cash as a result of the net proceeds of $223.6 million from the March
and April 1998 issuance of the 4.5% convertible subordinated notes after the
payment of approximately $122.0 million of outstanding borrowings under the
senior credit facility, debt assumed in the merger with Preferred Payment
Systems and the payment to Preferred Payment Systems dissenting shareholders.


OTHER, NET

     Other income increased $0.4 million in the third quarter of 1999 to $0.4
million from $21,000 in the third quarter of 1998 and increased $0.2 million for
the first nine months of 1999 to $0.1 million from other expense of $0.1 million
for the first nine months of 1998. Other income and expense, net primarily
relates to minority interests.

PROVISION FOR INCOME TAXES

     We recorded a tax benefit of $3.2 million in the third quarter of 1999
versus a tax provision of $9.0 million in the third quarter of 1998. The
effective tax rate was 7.0% and 42.0% in the third quarters of 1999 and 1998,
respectively. We recorded a tax provision of $9.8 million for the first nine
months of 1999 versus a tax provision of $23.8 million for the first nine months
of 1998. The effective tax rate was (67.1%) and 46.4% for the first nine months
of 1999 and 1998, respectively. Excluding the tax effects of the non-recurring
charges, the effective tax rate would have been 58.4% and 42.0% for the third
quarters of 1999 and 1998, respectively, and 46.2% and 42.0% for the first nine
months of 1999 and 1998, respectively. The above disparities in the effective
tax rates excluding the tax effects of the non-recurring charges is the result
of the impact of the non-deductibility of certain fees and expenses associated
with the merger in 1999 and the Preferred Payment Systems merger in 1998. We
expect to continue to provide for taxes at an effective tax rate of
approximately 46% for the remainder of the year as the increase in interest
expense and goodwill amortization from the change in the amortization period to
25 years in 1999 versus 30 to 40 years in 1998 results in lower pre-tax earnings
while expense items not deductible for tax, goodwill and non-deductible meals
and entertainment, result in a higher tax provision.


RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1998 AND 1997

REVENUES

     Our total revenues increased 24.9% in 1998 to $611.1 million from $489.3
million in 1997. Health Services' revenues increased 24.9% in 1998 to $259.5
million from $207.7 million in 1997. Managed Care Services' revenues increased
24.8% in 1998 to $351.6 million from $281.6 million in 1997, as our specialized
cost containment revenues increased 28.6% in 1998 to $183.7 million from $142.9
million in 1997 and our field case management revenues increased 21.0% in 1998
to $167.8 million from $138.7 million in 1997.

     Health Services' revenue growth was due to:

     o  our acquisition of 16 occupation healthcare centers;

     o  our management of an additional four occupational healthcare centers
        from Vencor, Inc. in the fourth quarter of 1997;

     o  an increase in business in our existing markets;

     o  development of sites in new markets; and

     o  an increase in our consulting and other ancillary services.

     Managed Care Services' specialized cost containment revenue growth is
largely attributable to:

     o  the growth of Preferred Payment Systems through its acquisition of About
        Health, First Notice Systems and other immaterial entities; and

     o  the growth in retrospective medical bill review, telephonic case
        management and claims reviews services in our existing service
        locations.

     Managed Care Services' field case management revenue growth is primarily
due to the business we generated from two field case management acquisitions and
the continued growth in revenues from our existing service locations.

     Our total contractual allowances offset against revenues during the years
ended December 31, 1998 and 1997 were $16.1 million and $14.7 million,
respectively.


COST OF SERVICES

     Our total cost of services increased 25.9% 1998 to $469.3 million from
$372.6 million in 1997. Health Services' cost of services increased 29.5% in
1998 to $201.2 million from $155.4 million in 1997, while Managed Care Services'
cost of services increased 23.4% in 1998 to $268.1 million from $217.3 million
in 1997.


                                       41
<PAGE>


     Our total gross profit margins decreased slightly to 23.2% in 1998 compared
to 23.8% in 1997. Health Services' gross profit margins decreased to 22.5% in
1998 compared to 25.2% in 1997, while Managed Care Services' gross profit
margins increased to 23.7% in 1998 compared to 22.9% in 1997.

     Health Services' gross profit margins decreased principally because of:

     o  an acceleration in the roll-out of patient tracking and billing systems
        into our occupational healthcare centers;

     o  increased spending on marketing and facility improvements; and

     o  the impact of lower gross profit margins from practices recently
        acquired and developed.

     Historically, as we consolidate certain functions, make other staff-related
changes, plus experience an increase in patient volume, the gross profit margins
of our acquired or developed practices have tended to improve.

     Managed Care Services has seen improvement in gross profit margins
primarily because of a shift in its revenue mix towards specialized cost
containment services, including the services provided by Preferred Payment
Systems, About Health and First Notice Systems. Revenues from these services
have historically had higher gross profit margins than revenues derived from
field case management. Although gross profit margins improved slightly in 1998,
they were negatively affected by a decrease in provider bill review gross profit
margins and a slow down in the growth of field case management revenues and
resulting gross profit margins. The provider bill review gross profit margins
decrease was due primarily to start-up costs, pricing concessions on new
customers and an increase in the level of uncollectible accounts receivable
charges. We expect the gross profit margins for provider bill review to continue
to be affected negatively for the first half of 1999 compared to the first half
of 1998 due to the impact of pricing concessions made in the second half of 1998
and a higher level of bad debt provision.


GENERAL AND ADMINISTRATIVE EXPENSES

     Our general and administrative expenses increased 13.8% in 1998 to $45.3
million from $39.8 million in 1997, or 7.4% and 8.1% as a percentage of revenue
for 1998 and 1997, respectively. The increase in general and administrative
expenses in 1998 were due primarily to the continued investment in our
Information Services and Technology Group and in our accounting and
administrative personnel.


AMORTIZATION OF INTANGIBLES

     Our amortization of intangibles increased 37.4% in 1998 to $8.1 million
from $5.9 million in 1997, or 1.3% and 1.2% as a percentage of revenues for 1998
and 1997, respectively. This increase is the result of amortizing additional
intangible assets such as:

     o  goodwill;

     o  customer lists and assembled workforces primarily associated with the
        purchases of First Notice Systems and About Health by Preferred Payment
        Systems;

     o  certain occupational healthcare centers from Vencor, Inc.; and

     o  various smaller acquisitions by Health Services.


NON-RECURRING CHARGE

     We recorded non-recurring charges for the years ended December 31, 1997 and
1998 of $38.6 million and $33.1 million, respectively.

     In the first quarter of 1998, we recorded a non-recurring charge of $12.6
million because of our merger of Preferred Payment Systems. The utilization of
this charge through December 31, 1998, was approximately:

                                       42
<PAGE>

     o  $5.1 million for professional fees and services;

     o  $2.4 million in costs associated with personnel reductions;

     o  $0.7 million in facility consolidations and closings;

     o  $1.6 million associated with the write-off of deferred financing fees on
        Preferred Payment; and

     o  $1.3 million of other non-recurring costs.

     At December 31, 1998, approximately $1.5 million of the non-recurring
charge remains primarily related to remaining facility lease obligations.

     In the fourth quarter of 1998, we recorded a non-recurring charge of $20.5
million primarily associated with our reorganization of Managed Care Services.
The utilization of this charge through December 31, 1998 was approximately:

     o  $7.4 million in charges related to the recognition of an impairment loss
        on the intangible related to an acquired contract;

     o  $2.5 million in costs associated with personnel reductions; and

     o  $1.1 million in facility consolidations.

     At December 31, 1998, approximately $9.5 million of the non-recurring
charge remains primarily related to remaining facility lease obligations and
costs associated with settling claims on other expired contracts.

     Our reorganization plan for Managed Care Services, including headcount
reductions and facility consolidations, was developed between early September
and the end of October 1998. We carried out the reorganization plan in late
October and early November 1998 with the headcount reductions of 168 employees
completed and most of the facility consolidations completed or underway in the
fourth quarter of 1998. The restructuring plan has not changed significantly
from our original estimate since most of the actions were completed or underway
by December 31, 1998. We are realizing savings of approximately $2.4 million per
quarter in personnel and facility related expenses and have not experienced any
significant interruptions in our operations as a result of the restructuring.

     In the third quarter of 1997, we recorded a non-recurring charge of $38.6
million associated with the merger of CRA and OccuSystems. We finalized our
merger and transition plan during the third quarter of 1997 with much of the
detailed planning occurring in August and September 1997, prior to the end of
the quarter. The merger and transition plan was approved by senior management in
September 1997 and we identified all significant actions to be taken, including
reductions in duplicative personnel. The utilization of this charge through
December 31, 1998, was approximately:

     o  $11.6 million for professional fees and services;

     o  $16.2 million in costs associated with personnel reductions and the
        consolidation of CRA's and OccuSystems' employee benefits;

     o  $5.9 million in facility consolidations and closings;

     o  $2.5 million for the write-off of start-up costs; and

     o  $2.4 million of other charges.

     We expect to expend approximately $8.4 million over the next twelve months
relating to the first quarter of 1998 and the fourth quarter of 1998
non-recurring charges, consisting of approximately:

                                       43
<PAGE>

     o  $1.8 million of severance related costs;

     o  $3.2 million of facility related costs;

     o  $3.0 million of cost associated with setting claims on expired
        contracts; and

     o  $0.4 million of other costs.


INTEREST EXPENSE

     Our interest expense increased $5.4 million in 1998 to $18.0 million from
$12.7 million in 1997 due primarily to our higher outstanding borrowings under
our existing credit facilities to finance acquisitions and the issuance of our
4.5% convertible subordinated notes, offset by the repayment of borrowings under
our existing credit facility and debt assumed in our merger with Preferred
Payment Systems.


INTEREST INCOME

     Our interest income increased $2.4 million in 1998 to $4.7 million from
$2.3 million in 1997 due principally the increase in our investment of excess
cash as a result of the receipt of $223.6 million in net proceeds from the
issuance of our 4.5% convertible subordinated notes after the payment of:

     o  approximately $122.0 million of outstanding borrowings under our
        existing credit facility;

     o  debt assumed in the merger of Preferred Payment Systems; and

     o  the payment to Preferred Payment Systems dissenting shareholders.


OTHER EXPENSE, NET

     Our other expense, net primarily consists of minority investors earnings in
consolidated affiliates of $0.5 million and amortization of start-up costs of
$0.3 million in 1997, partially offset by earnings in unconsolidated affiliates.


PROVISION FOR INCOME TAXES

     Our provision for income taxes in 1998 and 1997 was $19.3 million and $11.1
million, respectively. On a pro forma basis, giving effect to the Preferred
Payment Systems merger, our provision for income taxes in 1998 and 1997 would
have been $19.3 million and $13.9 million, respectively. This would have
resulted in pro forma effective tax rates of 46.2% and 65.9%, respectively.
Excluding the tax effects of our non-recurring charges in the third quarter of
1997, the first quarter of 1998 and the fourth quarter of 1998, the pro forma
effective tax rate would have been 41.0% for 1998 and 39.3% for 1997. We expect
to provide for our taxes at an effective tax rate of approximately 41% to 42%
for 1999.


RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996

REVENUES

     Our total revenues increased 31.3% in 1997 to $489.3 million from $372.7
million in 1996. Health Services' revenues increased 22.1% in 1997 to $207.7
million from $170.0 million in 1996. Managed Care Services' revenues increased
39.0% in 1997 to $281.6 million from $202.6 million in 1996, as specialized cost
containment revenues increased 70.6% in 1997 to $142.9 million from $83.8
million in 1996 and field case management revenues increased 16.7% in 1997 to
$138.7 million from $118.9 million in 1996.

     Health Services' revenue growth resulted from:

     o  the acquisition of 16 occupational healthcare centers;

                                       44
<PAGE>

     o  the management of an additional four occupational healthcare centers
        from Vencor, Inc. in the fourth quarter of 1997;

     o  an increase in business in our existing markets;

     o  development of sites in new markets; and

     o  an increase in consulting and other ancillary services.

     Managed Care Services' specialized cost containment revenue growth is
largely attributable to:

     o  the acquisitions of Focus, Prompt, First Notice Systems and About
        Health; and

     o  the growth in retrospective medical bill review, telephonic case
        management and claims review services in existing service locations and
        the expansion into additional service locations.

     Managed Care Services' field case management revenue growth is primarily
due to growth in revenues from existing service locations, and our opening of 13
offices during 1996 and 1997.

     Our total contractual allowances offset against revenues during the years
ended December 31, 1997 and 1996 were $14.7 million and $3.7 million,
respectively.


COST OF SERVICES

     Our total cost of services increased 28.5% in 1997 to $372.6 million from
$289.9 million in 1996. Health Services' cost of services increased 18.8% in
1997 to $155.4 million from $130.8 million in 1996, while Managed Care Services'
cost of services increased 36.5% in 1997 to $217.3 million from $159.2 million
in 1996.

     Our total gross profit margins increased to 23.8% in 1997 compared to 22.2%
in 1996. Health Services' gross profit margins increased to 25.2% in 1997
compared to 23.1% in 1996, while Managed Care Services' gross profit margins
increased to 22.9% in 1997 compared to 21.5% in 1996.

     Health Services' gross profit margin improvement has resulted from
increased efficiencies and productivity. Managed Care Services has seen
improvement in gross profit margin primarily resulting from a shift in its
revenue mix towards specialized cost containment services, including those
services provided by Focus, Prompt, First Notice Systems and About Health, which
historically have had higher gross profit margins than revenues derived from
field case management.


GENERAL AND ADMINISTRATIVE EXPENSES

     Our general and administrative expenses increased 20.1% in 1997 to $39.8
million from $33.2 million in 1996, or 8.1% and 8.9% as a percentage of revenue
for 1997 and 1996 respectively. This increase in general and administrative
expenses was principally attributable to expenses associated with acquisitions
and our continued investment in the Information Services and Technology Group.


AMORTIZATION OF INTANGIBLES

     Our amortization of intangibles increased 71.6% in 1997 to $5.9 million
from $3.4 million in 1996, or 1.2% and 0.9% as a percentage of revenues for 1997
and 1996, respectively. This increase is the result of amortizing additional
intangible assets such as goodwill, customer lists and assembled workforces
primarily associated with the purchase of:

     o  Focus;

     o  Prompt;

     o  First Notice Systems;

                                       45
<PAGE>

     o  About Health by Preferred Payment Systems;

     o  some occupational healthcare centers from Vencor, Inc.; and

     o  other smaller acquisitions.


NON-RECURRING CHARGE

     We recorded a non-recurring charge of $38.6 million associated with the
1997 merger of CRA and OccuSystems. The charges we incurred were approximately:

     o  $11.6 million for professional fees and services;

     o  $16.2 million in costs associated with personnel reductions and the
        consolidation of CRA's and OccuSystem's employee benefits;

     o  $5.9 million in facility consolidations and closings;

     o  $2.5 million for the write-off of start-up costs; and

     o  $2.4 million of other charges.

     At December 31, 1997, approximately $7.5 million of the non-recurring
charge remains primarily related to personnel-related charges and facility
consolidations and closings.


INTEREST EXPENSE

     Our interest expense increased $8.9 million in 1997 to $12.7 million from
$3.7 million in 1996 due primarily to the issuance of $97.8 million principal
amount of our 6% convertible subordinated notes in December 1996, the issuance
of indebtedness by Preferred Payment Systems in August 1996 and to increased
outstanding credit facility borrowings used to finance certain acquisitions.


INTEREST INCOME

     Our interest income increased $1.4 million in 1997 to $2.3 million from
$0.9 million in 1996 due primarily to the investment of excess cash generated
from the issuance of our 6% convertible subordinated notes until the funds were
utilized to finance certain acquisitions.


OTHER EXPENSE, NET

     Our other expense, net is primarily made up of minority investors' earnings
in consolidated affiliates. These amounts remained consistent between 1996 and
1997 at $0.9 million.


PROVISION FOR INCOME TAXES

     Our provision for income taxes in 1997 and 1996 was $11.1 million and $13.4
million, respectively. On a pro forma basis, giving effect to the Preferred
Payment Systems merger, our provision for income taxes in 1997 and 1996 would
have been $13.9 million and $16.2 million, respectively, resulting in pro forma
effective tax rates of 65.9% and 39.0%, respectively. Excluding the tax effects
of the non-recurring charge, our pro forma effective tax rate would have been
39.3% for 1997.

SEASONALITY

     Our business is seasonal in nature. Patient visits at our Health Services'
medical centers are lower in the first and fourth quarters primarily because of
fewer occupational injuries and illnesses during those time periods due to

                                       46
<PAGE>

plant closings, vacations and holidays. In addition, since employers generally
hire fewer employees in the fourth quarter, the number of pre-placement physical
examinations and drug and alcohol tests conducted at the medical centers during
that quarter is further reduced. Managed Care Services' field case management
revenues have historically been flat in the fourth quarter compared to the third
quarter due to the impact of vacations and holidays. Although our revenue growth
may obscure the effect of seasonality in our financial results, the first and
fourth quarters generally reflect lower revenues when compared to our second and
third quarters.

INFORMATION SYSTEMS--YEAR 2000

     The Year 2000 concern, which is common to most companies, concerns the
inability of information and non-information systems, primarily computer
software programs, to properly recognize and process date sensitive information
as the Year 2000 approaches. System database modifications and/or implementation
modifications will be required to enable such information and non-information
systems to distinguish between 21st and 20th century dates. We have completed a
number of acquisitions in recent years, and the information systems of some of
the acquired operations have not been fully integrated with our information
systems.

     We have formed a Year 2000 Program Office to provide a centralized
management function for our entire organization that will assist in identifying,
addressing and monitoring our Year 2000 readiness and compliance programs. Our
Year 2000 Program Office has organized teams at each division to research Year
2000 compliance status and implement the appropriate solutions. Our Year 2000
Program includes five phases -- awareness, assessment, remediation, testing and
implementation. The awareness and assessment phases are complete and the
remediation, testing and implementation phases are substantially complete.

     Our Year 2000 Program Office engaged an outside consultant to assist in an
inventory and assessment of Year 2000 affected areas, with a primary focus on
information technology systems, third party software and key suppliers and
selected customers. This inventory and assessment was completed in the fourth
quarter of 1998. Our Year 2000 Program Office also engaged an outside consultant
in the first quarter of 1999 to assist in inventory, assessment and remediation
efforts of our information systems infrastructure Year 2000 compliance. The
remediation of our information systems infrastructure was substantially complete
by the third quarter of 1999. We completed in the fourth quarter of 1998 an
internal inventory and assessment of non-information technology systems, e.g.
embedded systems contained in medical equipment. The remediation or replacement
efforts of our information systems infrastructure and non-information technology
systems was substantially complete by the end of the third quarter of 1999.

     Our Year 2000 Program Office has established a vendor management program
protocol for soliciting Year 2000 compliance information from third parties and
requests for compliance information from all key suppliers and selected
customers were sent in the fourth quarter of 1998 and the first quarter of 1999.
We gathered Year 2000 compliance information from third parties and received the
majority of third party responses by the end of the third quarter of 1999. To
the extent responses have not been received, the division Year 2000 sponsors and
coordinators have ranked the third parties by level of importance to their
operations. Our Year 2000 Program Office conducted phone surveys, sent
additional mailings and performed research of public information issued by the
third-party, i.e., "web research." These responses have provided compliancy
status information that enables us to determine the extent to which the Company
may be vulnerable to those third parties' failure to remediate their own Year
2000 issues. The vendor management program provides, on an ongoing basis, the
compliancy response information to the divisions for their evaluation and
determination if any action is required. The vendor management program was
substantially completed by October 31, 1999.

     Our identified Year 2000 projects overlap with our ongoing investments in
information technology, as such, there are presently Year 2000 projects at the
remediation, testing and implementation phases. We believe that we have
identified most "mission critical" issues and have executed or are executing
appropriate action plans which may include software upgrades, replacement of
noncompliant components or referral of problems related to third party-provided
software to the original supplier. We have prepared our plans to have all
"mission critical" projects Year 2000 compliant by the end of the fourth quarter
of 1999. The majority of the "mission critical" projects have been remediated,
tested and deployed as of October 31, 1999. While some non-critical systems may
not be addressed until after December 1999, we believe those systems will not
disrupt our operations in a material manner. Any additional issues that may
arise will be classified as either "mission critical" or non-critical, and

                                       47
<PAGE>

appropriate action plans will be developed and implemented. We will continue to
formulate, evaluate and refine contingency plans deemed necessary in the
fourth quarter of 1999.

     We currently estimate that the total cost of implementing our Year 2000
Program will be between $5.0 million and $10.0 million. This estimate is based
upon presently available information and will be updated as we continue through
implementation. It is expected these costs will not be significantly different
from our current planned investment for information technology, and therefore,
should not have a material adverse effect on our long-term results of
operations, liquidity or consolidated financial position. We made capital and
noncapital investments in the Information Services and Technology Group of
approximately $32.0 million in 1998 and expect our investment in 1999 to
approximate $40.0 million. Of this investment, our Year 2000 Program Office
incurred expenses of approximately $1.9 million through September 30, 1999
primarily associated with the engagement of outside consultants to assist in the
inventory, assessment and remediation of Year 2000 affected areas.

     Although we do not anticipate any disruption in our operations or financial
reporting as a result of system upgrades or system integrations, we cannot
assure you that such disruption will not occur or that the desired benefits from
the Year 2000 compliance of our information and non-information systems will be
realized. If we do not identify and remediate Year 2000 issues prior to January
1, 2000, our operations could be disrupted which could have a material adverse
effect on our business or operating results or financial condition. In addition,
we place a high degree of reliance on computer systems of third parties, such as
customers, trade suppliers and computer hardware and commercial software
suppliers. Although we are assessing the readiness of these third parties, there
can be no guarantee that the failure of these third parties to modify their
systems in advance of December 31, 1999 would not have a material adverse effect
on us. In addition, our operations could be disrupted if the companies with
which we do business do not identify and correct any Year 2000 issues and such
failure adversely affects their ability to do business with us. If all Year 2000
issues are not identified and all action plans are not completed and contingency
plans become necessary, we may not be Year 2000 compliant which could have a
material adverse effect on our long-term results of operations, liquidity, or
consolidated financial position. The amount of potential liability and lost
revenue has not been estimated.


LIQUIDITY AND CAPITAL RESOURCES

     Cash flows generated from (used for) operations were $34.9 million, ($0.5
million) and $15.6 million for the years ended December 31, 1998, 1997 and 1996,
respectively, and $4.3 million and $30.0 million for the first nine months of
1999 and 1998, respectively. During 1998, working capital used $20.3 million of
cash primarily due to an increase in accounts receivable of $19.8 million,
offset by a decrease in prepaid expenses and income taxes of $1.5 million and an
increase in accounts payable, accrued expenses and income taxes of $0.9 million.
Accounts receivable increased primarily due to continued revenue growth, while
accounts payable, accrued expenses and income taxes increased due to the timing
of payments and the remaining obligations relating to the first quarter and
fourth quarter of 1998 non-recurring charges. During the first nine months of
1999, working capital used $13.0 million of cash due primarily to an increase in
accounts receivable of $23.7 million and prepaid expenses of $1.0 million
partially offset by an increase in accounts payable and accrued expenses of
$11.7 million. Within the next twelve months, it is anticipated that
approximately $11.3 million in cash payments will be made related to the
non-recurring charges that occurred in the first quarter of 1998, fourth quarter
of 1998 and the third quarter of 1999. These expenditures are anticipated to
consist of $5.6 million of fees and other expenses related to the merger, $0.4
million of severance related costs, $3.9 million of facility related costs, $1.4
million of costs associated with settling claims on certain expired contracts.

     We used net cash of $18.1 million in connection with acquisitions, $15.5
million to purchase marketable securities and $34.2 million of cash to purchase
property and equipment during 1998, the majority of which was spent on new
computer hardware and software technology. During the first nine months of 1999,
we used net cash of $43.3 million in connection with acquisitions and $26.0
million to purchase property and equipment, the majority of which was spent on
new computer and software technology, partially offset by $15.5 million provided
by the sale of marketable securities.


                                       48
<PAGE>


     Cash flows provided by financing activities of $121.6 million in 1998 was
due primarily to the issuance of $230.0 million principal amount of our 4.5%
convertible subordinated notes, $223.6 million, net of deferred finance fees. A
portion of the proceeds from the issuance of our 4.5% convertible subordinated
notes was used to:

     o  repay borrowings under our existing credit facility;

     o  repay debt assumed in our merger with Preferred Payment Systems; and

     o  for the payment of $15.0 million to Preferred Payment Systems dissenting
        shareholders.

     Net proceeds from the issuance of common stock under employee stock
purchase and option plans and the related tax benefit was $14.4 million. Cash
flows used by financing activities of $41.1 million in the nine months ended
September 30, 1999 was due primarily to the payment of fees and expenses related
to the merger and deferred finance fees relatd to the merger financing. Our
capital and non-capital investment in the Information Services and Technology
Group was approximately $32.0 million in 1998 and expected to be approximately
$40.0 million in 1999.

     We were in compliance with our covenants, including our financial covenant
ratio tests, in the third quarter of 1999. We had borrowings outstanding under
the revolving credit facility of $1.5 million as of September 30, 1999 and
anticipate borrowings to increase to approximately $20.0 million to $25.0
million as of December 31, 1999 due to Merger related payments of fees and
expenses, capital expenditures and anticipated fourth quarter of 1999
acquisitions.

     We 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 at least the next twelve
months. 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 sure that any future debt or equity financing will be available on
terms favorable to us.


LEGAL PROCEEDINGS

     As of November 1, 1999, we were aware of one consolidated lawsuit that was
originally filed in three suits by alleged stockholders of Concentra relating to
our merger with Yankee. All three lawsuits were filed in the Chancery Court for
New Castle County, Delaware. Each lawsuit named Concentra, its directors and
Yankee as defendants. The plaintiffs in each lawsuit sought to represent a
putative class of all public holders of Concentra common stock.

     The lawsuits alleged, among other things, that Concentra's directors
breached their fiduciary duties to their stockholders by approving our merger.
Specifically, the directors were alleged to have breached their fiduciary duties
of care and loyalty by failing to conduct an impartial auction to determine the
maximum value attainable for the common stock of Concentra. The complaints
alleged that certain relationships between Welsh Carson and Concentra caused
Concentra's directors to favor Welsh Carson throughout the sale of Concentra and
to enter into a merger agreement that had the effect of capping the price of
Concentra's stock. The lawsuits sought among other things, preliminary and
permanent injunctive relief prohibiting consummation of the merger, unspecified
damages, attorneys' fees and other relief.

     We have reached an agreement in principle to settle all outstanding class
action litigation filed in connection with the merger. Under the terms of the
settlement, we agreed to make certain amendments to the proxy statement mailed
to our stockholders with respect to the merger. In return, we, Welsh Carson and
their respective affiliates, officers, directors and other representatives will
be released from all claims of the class. The settlement is conditioned upon the
closing of the merger, the execution of definitive settlement documents and
court approval. Under the terms of the proposed settlement, the defendants
agreed to pay up to $325,000 in court-awarded attorneys' fees and expenses.

                                       49

                                    BUSINESS

      We are the largest company dedicated primarily to serving the occupational
healthcare market. We provide initial treatment for approximately 4% of
workplace injuries in the United States and perform non-injury occupational
healthcare services for over 80,000 local employers. We provide specialized cost
containment and field case management services to over 2,000 customers across
the United States and Canada, including most of the major underwriters of
worker's compensation insurance, third-party administrators and self-insured
employers. We are also the largest provider of out-of-network bill review
services to the group health marketplace. We offer a continuum of
healthcare-related services to employers, insurers and third-party
administrators of all sizes and are compensated for our services on a
non-risk-bearing, fee-for-service or percentage-of-savings basis. Less than 0.5%
of our revenues are dependent on Medicare or Medicaid reimbursement.

      Our services reduce the customer's healthcare costs by:

      o    efficiently managing the application of care and the return-to-work
           process, thereby providing appropriate medical care while reducing
           the non-medical costs associated with a claim; and

      o    using sophisticated cost containment techniques to determine the
           proper pricing of care once it has been administered.

      We believe that by offering both the provision of care and claims
management services, we are in a unique position to provide comprehensive,
integrated services on a bundled or unbundled basis to national or regional
accounts and local employers. In addition to the occupational healthcare and
group health markets, we also provide cost containment services to the auto
insurance market as well as social security disability advocacy services to the
long-term disability insurance market. In 1998, we generated revenues and
Adjusted EBITDA of $611.1 million and $111.7 million, respectively.

      With healthcare costs rising, we believe that payors will seek to increase
the use of cost saving strategies, such as those we offer, to minimize these
costs. Our comprehensive services are comprised of three distinct categories:

      o    healthcare services;

      o    specialized cost containment services; and

      o    field case management services.

      We provide healthcare services through our network of 201 owned and
managed occupational healthcare centers, located in 60 markets in 32 states as
of November 1, 1999. As a primary starting point for the provision of care in
the workers' compensation market, our occupational healthcare centers are
designed to efficiently provide quality care to patients while also providing an
entry point for our other cost containment services. Healthcare services include
injury care and physical therapy services for work-related injuries and
illnesses, physical examinations, substance abuse testing and certain other loss
prevention services. In 1998, revenues from healthcare services represented
approximately 42% of our total revenues.

      Specialized cost containment services consist of first report of injury,
telephonic case management, utilization management, both in- and out-of-network
bill review, preferred provider organization network access, independent medical
exams and peer reviews. These specialized cost containment services are designed
to monitor the timing and appropriateness of medical care, as well as the proper
pricing for that care. These services are primarily provided to the workers'
compensation market, except for out-of-network bill review which we provide to
the group health market. We are currently expanding our out-of-network bill
review services to the workers' compensation and auto insurance markets. In
1998, revenues from specialized cost containment services represented
approximately 30% of our total revenues.

      We provide field case management services to a national customer base
using approximately 1,000 full-time field case managers. Field case management
services involve working on a one-on-one basis with injured employees


                                       50
<PAGE>

and aiding communication among their various healthcare professionals, employers
and insurance  company  adjusters.  Field case management  services are designed
both to assist in maximizing  medical  improvement  and, where  appropriate,  to
expedite return to work. In 1998,  revenues from field case management  services
represented approximately 28% of our total revenues.


INDUSTRY OVERVIEW

OCCUPATIONAL HEALTHCARE

      Occupational healthcare is largely provided by independent physicians, who
have experienced increasing pressures in recent years from growing regulatory
complexity and other factors, as well as hospital emergency departments and
other urgent care providers. We anticipate that competition in the occupational
healthcare market may shift to specialized provider groups, such as groups we
manage. Occupational healthcare services consist of two primary components:

      o    workers' compensation injury care and related services; and

      o    non-injury occupational healthcare services related to employer needs
           or statutory requirements.


      WORKERS' COMPENSATION INJURY CARE

      Workers' compensation is a state-mandated, comprehensive insurance program
that requires employers to fund all medical expenses, lost wages and other costs
resulting from work-related injuries and illnesses with no co-payment from the
employee. Since their introduction in the early 1900s, these programs have been
expanded to all fifty states, the District of Columbia and Canada. In addition,
federal statutes provide workers' compensation benefits for federal employees.
Each state is responsible for implementing and regulating its own program.
Consequently, workers' compensation benefits and arrangements vary on a
state-by-state basis and are often highly complex.

      Workers' compensation legislation generally requires employers, directly
or indirectly through an insurance vehicle, to fund all of an employee's costs
of medical treatment and related lost wages, legal fees and other associated
costs. Typically, work-related injuries are broadly defined, and injured or ill
employees are entitled to extensive benefits. Employers are required, directly
or indirectly, to provide first-dollar coverage with no co-payment or deductible
due from the injured or ill employee for medical treatment and, in many states,
there is no lifetime limit on expenses. However, in exchange for providing this
coverage for employees, employers are not subject to litigation by employees for
benefits in excess of those provided pursuant to the relevant state statute. The
extensive benefits coverage, for both medical costs and lost wages, is provided
through the purchase of commercial insurance from private insurance companies,
participation in state-run insurance funds or employer self-insurance.

      According to the Workers' Compensation Monitor data published in the 1998
Workers' Compensation Year Book, total workers' compensation costs to employers
in the United States were estimated to be approximately $92.7 billion in 1996.
Although the industry as a whole is fragmented with a large number of
competitors in the various sub-segments of workers' compensation services, we
believe that we are the only integrated provider of healthcare management and
cost containment services offering a full range of services on a nationwide
basis.

      The dollar amount of workers' compensation claims has increased
significantly in recent years, resulting in escalating costs to employers. We
believe that workers' compensation costs will continue to rise primarily because
of:

      o    broader definitions of work-related injuries and illnesses covered
           by workers' compensation laws;

      o    the shifting of medical costs from group health plans to the workers'
           compensation system;

      o    an aging work force;

                                       51
<PAGE>




      o    the continued requirement that employers pay all of an employee's
           cost of medical treatment, without any co-payment or deductible, and
           related lost wages and non-medical costs; and

      o    the under-use to date of comprehensive cost containment programs in
           the workers compensation industry.

      As workers' compensation costs increase, we expect that employers will
continue to seek and use strategies and programs to reduce workers' compensation
costs and to improve worker productivity, health and safety. We believe that
clients' use of our healthcare services at the primary care level, focusing on
proactively managing each injury episode and encouraging early return to work,
as appropriate, can result in substantial savings in indemnity and medical
costs.

      Provider reimbursement methods vary on a state-by-state basis. As of March
1998, 40 states have adopted fee schedules under which all healthcare providers
are uniformly reimbursed. The fee schedules are set by each state and generally
prescribe the maximum amounts that may be reimbursed for a designated procedure.
In states without fee schedules, healthcare providers are reimbursed based on
usual, customary and reasonable fees charged in the particular state in which
the services are provided. These usual, customary and reasonable fees are
commonly called UCR. Of the 32 states in which we currently operate occupational
healthcare centers, as of November 1999, 24 have fee schedules.

      Limits on an employee's right to choose a specific healthcare provider
depend on the particular state statute. According to the Workers' Compensation
Research Institute, as of March 1998, 25 states limited the employee's initial
choice of provider, two states prohibited employee change of provider and 37
states and the District of Columbia placed restrictions on all employees
switching providers, including provisions requiring employer approval for any
changes. Generally, the employer will also have the ability to direct the
employee when the employer is self-insured. It has been our experience that our
results of operations and prospects in a particular state do not materially
depend on state statutes regarding direction of care. Consequently, we believe
that employers greatly influence their employees' choices of physicians even in
states in which the employees may select their providers.


      NON-INJURY HEALTHCARE SERVICES

      Non-injury occupational healthcare services include:

      o    employment-related physical examinations;

      o    drug and alcohol testing;

      o    functional capacity testing; and

      o    other related programs designed to meet specific employer needs.

      Non-injury healthcare services also include programs to assist employers
in complying with a continuously expanding list of federal and state
requirements, including hearing conservation programs, toxic chemical exposure
surveillance and monitoring programs, and Department of Transportation and
Federal Aviation Administration-mandated physical examinations. Federal laws
governing health issues in the workplace, including the Americans with
Disabilities Act, have increased employers' demand for healthcare professionals
who are experts in the delivery of these regulated services.


COST CONTAINMENT SERVICES

      Cost containment techniques are intended to control the cost of healthcare
services and to measure the performance of providers of healthcare through
intervention and on-going review of proposed services and services actually
provided. Managed care techniques were originally developed to stem the rising
costs of group healthcare. Historically, employers were slow to apply managed
care techniques to workers' compensation costs primarily because the total costs
are relatively small compared to those associated with group health benefits and
because


                                       52
<PAGE>

state-by-state  regulations  related to workers'  compensation  are more complex
than those related to group  health.  However,  in recent  years,  employers and
insurance  carriers have been  increasing  their focus on applying  managed care
techniques to control their workers' compensation costs.

      A number of states have adopted legislation encouraging the use of
workers' compensation managed care organizations in an effort to allow employers
to control their workers' compensation costs. Managed care organization laws
generally provide employers an opportunity to channel injured employees into
provider networks. In certain states, managed care organization laws require
licensed managed care organizations to offer certain specified services, such as
utilization management, case management, peer review and provider bill review.
Most of the managed care organization laws adopted to date establish a framework
within which a company such as ours can provide its customers a full range of
managed care services for greater cost control.

      Because workers' compensation benefits are mandated by law and are subject
to extensive regulation, payors and employers do not have the same flexibility
to alter benefits as they have with other health benefit programs. In addition,
workers' compensation programs vary from state to state, making it difficult for
payors and multi-state employers to adopt uniform policies to administer, manage
and control the costs of benefits. As a result, managing the cost of workers'
compensation requires approaches that are tailored to the specific state
regulatory environment in which the employer operates.

      Workers' compensation cost containment services include two broad
categories:

      o    specialized cost containment services; and

      o    field case management services.

      Specialized cost containment services are designed to reduce the cost of
workers' compensation claims through a variety of techniques such as:

      o    first report of injury;

      o    telephonic case management;

      o    utilization management;

      o    precertification and concurrent review;

      o    both in- and out-of-network bill review services;

      o    preferred provider organization network access;

      o    independent medical examinations; and

      o    peer reviews.

      Field case management services involve:

      o    working on a one-on-one basis with injured employees; and

      o facilitating communication among their various healthcare professionals,
        employers and insurance company adjusters.

      Field case management services are designed both to assist in maximizing
medical improvement and, where appropriate, to expedite return to work.


                                       53

GROUP HEALTH COST CONTAINMENT SERVICES

      According to the Health Insurance Association of America, private health
insurance claims payments were estimated to be approximately $281.7 billion in
1995. All healthcare payors have out-of-network exposure due to healthcare
claims that are outside their coverage area or network either as a matter of
choice on the part of the insured or as a result of geographic circumstances
where the insured does not have local access to contracted providers.
Out-of-network healthcare claims expose payors to a greater incidence of
over-use, cost-shifting, omission of appropriate discounts and possible billing
errors. Out-of-network bill review service providers produce savings for their
clients by analyzing these out-of-network medical claims and reducing the costs
which otherwise would be payable through a variety of methods, including
professional negotiation, line item analysis, specialized audit and bill review
processes and broad access to preferred provider networks.


OUR SERVICES AND OPERATIONS

      The workers' compensation and group health markets represent a significant
opportunity for the full range of healthcare management and cost containment
services we provide. In each of these markets, insurance companies, self-insured
employers and third party administrators have a need for our services as they
always try to control their rising healthcare costs.


HEALTHCARE SERVICES

      OCCUPATIONAL HEALTHCARE CENTERS

      Our 201 occupational healthcare centers at November 1, 1999 provide
treatment for:

      o    work-related injuries and illnesses;

      o    physical therapy;

      o    preplacement physical examinations and evaluations;

      o    certain diagnostic testing;

      o    drug and alcohol testing; and

      o    various other employer-requested or government-mandated occupational
           health services.

      During 1998, approximately 52% of all patient visits to our centers were
for the treatment of injuries or illnesses and 48% were for substance abuse
testing, physical examinations and other non-injury occupational healthcare
services.

      Each of our centers is staffed with at least one licensed physician who is
an employee of a physician group and at least one licensed physical therapist.
The licensed physicians are generally experienced in occupational medicine or
have emergency, family practice, internal medicine or general medicine
backgrounds. Most centers use a staff of between 10 and 15 full-time persons, or
their part-time equivalents, including licensed physicians, nurses, licensed
physical therapists and administrative support personnel.

      Physician and physical therapy services are provided at our occupational
healthcare centers under agreements with the physician groups, which are
independently organized professional corporations that hire licensed physicians
and physical therapists to provide healthcare services to the centers' patients.
The management agreements between us and our physician groups with respect to
the 346 affiliated physicians as of November 1, 1999 have 40-year terms.
Pursuant to each management agreement, we provide a wide array of business
services to the physician groups, such as:

      o    providing nurses and other medical support personnel;

                                       54
<PAGE>

      o    practice and facilities management;

      o    billing and collection;

      o    accounting;

      o    tax and financial management;

      o    human resource management;

      o    risk management;

      o    marketing and information-based services such as process management
           and outcome analysis.

      As another service to the physician groups, we recruit physicians, nurses,
physical therapists and other healthcare providers. We collect receivables on
behalf of the physician groups and advance funds for payment of each physician
group's expenses, including salaries, shortly after services are rendered to
patients. We receive a management fee based on all services performed at the
centers. The management fee is subject to renegotiation and may be adjusted from
time to time to reflect industry practice, business conditions and actual
expenses for contractual allowances and bad debts. We provide services to the
physician groups as an independent contractor and are responsible only for the
non-medical aspects of the physician groups' practices. The physician groups
retain sole responsibility for all medical decisions, including the hiring of
medical personnel.

      Individual physicians who perform services pursuant to contracts with a
physician group are employees of the physician group. The physicians providing
services for the physician groups do not maintain other practices. The owners of
the physicians group are physicians. It is the responsibility of the owners of
the physician group to hire and manage all physicians associated with the
physician group and to develop operating policies and procedures and
professional standards and controls. Under each management agreement, the
physician group indemnifies us from any loss or expense arising from acts or
omissions of the physician group or our professionals or other personnel,
including claims for malpractice.


      JOINT VENTURES AND MANAGEMENT AGREEMENTS

      Our strategy is to continue to develop clusters of occupational healthcare
centers in new and existing geographic markets through the acquisition and
development of occupational healthcare centers. In selected markets in which a
hospital management company, hospital system or other healthcare provider has a
significant presence, we may focus our expansion efforts on strategic joint
ventures or management contracts. In our joint venture relationships, we
typically acquire a majority ownership interest in the venture and agree to
manage the venture for a management fee based on net revenues. We currently
manage 11 joint ventures through which we operate 29 centers. In addition, we
have entered into three management agreements through which we operate six
centers.


      OTHER ANCILLARY PROGRAMS

      We offer other ancillary programs as described below. It has been our
experience that, by offering a full range of programs to complement our core
healthcare management services, it strengthens our relationships with existing
clients and increases the likelihood of attracting new clients. We anticipate
expanding our ancillary programs as needed to address occupational legislation
and regulations enacted in the future.

      COMPLIANCE WITH THE AMERICANS WITH DISABILITIES ACT. The Americans with
Disabilities Act is a federal statute that generally prohibits employers from
discriminating against qualified disabled individuals in the areas of the job
application process, hiring, discharge, compensation and job training. The
Americans with Disabilities Act now applies to all employers with 15 or more
employees. Through our "ADApt Program," we assist employers with the Americans
with Disabilities Act compliance issues by addressing the Americans with
Disabilities Act requirements relating to job descriptions, pre-placement
physical examinations, analysis and compliance and confidentiality of


                                       55
<PAGE>

applicant/employee  information.  ADApt helps  employers  adapt their hiring and
termination procedures,  job descriptions and injury/illness management programs
in order to comply with Americans with Disabilities Act guidelines.

      RISK ASSESSMENT AND INJURY PREVENTION PROGRAMS. We assist clients in
reducing workplace injuries and illnesses through our on-site risk assessment
and injury prevention programs. These programs include:

      o    identifying workplace hazards;

      o    designing plant-specific safety programs; and

      o    helping clients comply with federal and state occupational health
           regulations.

      We also provide ongoing educational programs for our clients.

      For 1998, revenues from healthcare services represented approximately 42%
of our total revenues.


SPECIALIZED COST CONTAINMENT SERVICES

      We provide a number of specialized services focused directly on helping to
reduce the medical and indemnity costs associated with workers' compensation and
the medical costs associated with group health claims. These specialized cost
containment services include:

      o    first report of injury;

      o    telephonic case management;

      o    utilization management;

      o    precertification and concurrent review;

      o    in- out-of-network bill review services;

      o    preferred provider organization network access;

      o    independent medical examinations;

      o    and peer reviews.

      We are able to offer our services separately or on a bundled basis as a
full-service managed care program, beginning with the first report of injury and
including all specialized cost containment services needed to aggressively
manage the costs associated with a work-related injury. Our comprehensive
approach to managing workers' compensation costs serves the needs of a broad
range of clients, from local adjusters to national accounts. In addition to
providing specialized cost containment services for work-related injuries and
illnesses, we also provide out-of-network bill review services to the group
health market, cost containment services to payors of automobile accident
medical claims and social security disability advocacy services to payors of
long term disability claims.

      We believe that the demand for specialized cost containment services will
continue to increase due to a number of factors, including:

      o    the increasing payor awareness of the availability of these
           techniques for cost containment and case management;

      o    the effectiveness of managed care techniques at reducing costs for
           group health insurance plans;


                                       56
<PAGE>



      o    the verifiable nature of the savings that can be obtained by
           application of specialized cost containment techniques applicable to
           workers' compensation; and

      o    the broad applicability of these techniques to all injured employees,
           not just severely injured employees likely to be absent from work.


      OUT-OF-NETWORK BILL REVIEW

      Through Concentra Preferred Systems, we continue to expand our market
presence in bill review services. We believe that Concentra Preferred Systems is
the market leader in this line of business in the group health market and is
expanding its services into the workers' compensation market in states that have
not established fee schedules and into the auto insurance market where
appropriate. Concentra Preferred Systems uses a variety of techniques to reduce
expenses by repricing hospital and other facilities' bills. Using its services,
Concentra Preferred Systems reduces costs ordinarily payable on medical bills
submitted by healthcare providers and the administrative expense associated with
reviewing and analyzing medical bills. These services include:

      o    professional fee negotiation;

      o    line-item analysis;

      o    other specialized audit and bill review processes; and

      o    access to a nationwide preferred provider organization network.

      Concentra Preferred Systems provides out-of-network bill review services
to healthcare payors in most risk categories:

      o    indemnity;

      o    preferred provider organization;

      o    health maintenance organization;

      o    ERISA self-insured plans;

      o    Taft-Hartley Plans;

      o    reinsurance carriers; and

      o    intermediaries such as administrative services organizations and
           third party administrators.

      Concentra Preferred Systems is the largest provider of these specific
services in the managed care industry and specializes in out-of-area and
non-network cost management services that reduce exposure to:

      o    over-use;

      o    upcoding;

      o    cost shifting;

      o    various forms of revenue enhancement tactics; and

      o    inflated retail charge practices.


                                       57
<PAGE>

      The current technology employed at Concentra Preferred Systems is designed
to:

      o    review most provider bill types;

      o    employ four transmission methods to aid the exchange of bill data;

      o    use various database technologies as part of the bill screening
           process;

      o    score each bill referred based on the individual service requirements
           of each client group; and

      o    route each bill to the most appropriate bill review service included
           in our range of cost containment services.

      Concentra Preferred Systems has packaged this process and markets it as
the Healthcare Bill Management System. The system affords large payor clients
breadth of service and capacity, consolidated and uniform cost management
capability, rigorous due diligence and high quality performance.


      FIRST REPORT OF INJURY

      Through First Notice Systems, we provide a computerized first report of
injury/loss reporting service using two centralized national call centers to
which an individual, employer or insurance company claims adjuster communicates
reports of injuries or losses as soon as they occur. First Notice Systems
provides its services primarily to the auto industry for first notice of loss
reporting and to workers' compensation carriers for first report of injuries
reporting, as well as to property and casualty carriers that write both auto and
workers' compensation insurance. For injuries, each report is electronically
transferred or mailed to the state agency, the employer and the insurance
company. This service assists in the timely preparation and distribution of
state-mandated injury reports, provides us and our customers with an early
intervention tool to maximize control over workers' compensation and auto claims
and also provides us with cross-selling and referral opportunities.


      TELEPHONIC CASE MANAGEMENT

      This service provides for short-duration of 30 to 90 days for telephonic
management of workers' compensation claims. The telephonic case management
units:

      o    accept first reports of injury;

      o    negotiate discounts with hospitals and other providers;

      o    identify care alternatives; and

      o    work with injured employees to minimize lost time on the job.

      Each of the telephonic case management units is overseen by nurses who are
experienced in medical case management. The telephonic case management units
represent an important component of early intervention and act as a referral
source of appropriate cases to our field case management offices.


      UTILIZATION MANAGEMENT: PRECERTIFICATION AND CONCURRENT REVIEW

      Our precertification and concurrent review services are used by clients to
ensure that certain medical procedures are precertified by one of our registered
nurses and/or physicians for medical necessity and appropriateness of treatment
before the medical procedure is performed. Our determinations represent only
recommendations to the customer, the ultimate decision to approve or disapprove
request is made by the claims adjuster. Precertification calls are made by
either the claimant or the provider to one of our national utilization
management reporting units. After a treatment plan has been precertified, one of
our employees performs a follow-up call, concurrent review, at the end of an
approved time period to evaluate compliance and/or discuss alternative plans.


                                       58

      BILL REVIEW

      Through a sophisticated software program, we review and reduce our
customers' medical bills, including hospital bills, to either the various
state-mandated fee schedules for workers' compensation claims or a percentage of
the UCR rates that exist in non-fee schedule states. Additionally, this
automated bill review service enables clients to access certain preferred
provider organization pricing schedules that represent additional savings below
the fee schedules or UCR rates. The savings to our clients as a result of this
service can be significant. Bill review also creates an important historical
database for provider practice patterns and managed care provider compliance
requirements.


      ACCESS TO PREFERRED PROVIDER NETWORKS

      Through Focus, we provide our clients with access to a national preferred
provider organization network. This network provides injured workers with access
to quality medical care at pre-negotiated volume discounts, thereby offering our
clients the ability to influence, or in certain states to direct, their
employees into the preferred provider organization network as a means of
managing their work-related claims. In addition to providing a vehicle for
managing the delivery of appropriate care by qualified providers, the discounts
associated with these preferred provider organization arrangements generate
additional savings through the retrospective bill review program described
above. Focus's national network includes approximately 227,000 individual
providers and over 2,800 hospitals covering 42 states and the District of
Columbia.


      INDEPENDENT MEDICAL EXAMS

      Independent medical examinations are provided to assess the extent and
nature of an employee's injury or illness. We provide our clients with access to
independent physicians who perform the independent medical examinations from 14
of our service locations and, upon completion, prepare reports describing their
findings.


      PEER REVIEWS

      Peer review services are provided by a physician, therapist, chiropractor
or other provider who reviews medical files to confirm that the care being
provided appears to be necessary and appropriate. The reviewer does not meet
with the patient, but merely reviews the file as presented.

      For 1998, revenues from specialized cost containment services represented
approximately 30% of our total revenues.


FIELD CASE MANAGEMENT SERVICES

      We provide field case management services to the workers' compensation
insurance industry through nurse case managers working at the local level on a
one-on-one basis with injured employees and their various healthcare
professionals, employers and insurance company adjusters. Our services are
designed to assist in maximizing medical improvement and, where appropriate, to
expedite employees' return to work through medical management and vocational
rehabilitation services.

      Our field case management services consist of one-on-one management of a
work-related injury by approximately 1,000 full-time field case managers in 89
offices in 49 states, the District of Columbia and Canada. This service
typically involves a case with a significant potential or actual amount of lost
work time or a catastrophic injury that requires detailed management and
therefore is referred out by the local adjuster to our marketer. Our field case
managers specialize in expediting the injured employee's return to work through
both medical management and vocational rehabilitation. Medical management
services provided by our field case managers include coordinating the efforts of
all the healthcare professionals involved and increasing the effectiveness of
the care being provided by encouraging compliance and active participation on
the part of the injured worker. Vocational rehabilitation services include job
analysis, work capacity assessments, labor market assessments, job placement
assistance and return to work coordination.


                                       59
<PAGE>

      We believe that the following factors will contribute to continued growth
of our field case management services:

      o    increased acceptance of field case management techniques due to
           greater exposure to the workers' compensation managed care market;

      o    earlier identification of individuals in need of field case
           management services due to increased utilization of our specialized
           cost containment services, particularly early intervention services;

      o    increased market share at the expense of smaller, undercapitalized
           competitors; and

      o    the ability to access national accounts for use of case management
           services.

      For 1998, revenues from field case management services represented
approximately 28% of our total revenues.


CUSTOMERS

      Our occupational healthcare centers currently serve more than 80,000
employers-including local offices of national companies-ranging from large
corporations to businesses with only a few employees. We serve more than 2,000
specialized cost containment and field case management customers across the
United States and Canada, including most of the major underwriters of workers'
compensation insurance, third party administrators and self-insured employers.

      We are compensated primarily on a fee-for-service or percentage-of-savings
basis. Our largest customer represented less than 6% of our total revenue in
1998. We have not entered into written agreements with most of our healthcare
services customers. Many of our specialized cost containment and field case
management relationships are based on written agreements. However, either we or
the customer can terminate most of these agreements on short notice. We have no
risk-bearing or capitated arrangements. Less than 0.5% of our revenues are
dependent on Medicare or Medicaid reimbursement.


SALES AND MARKETING

      We actively market our services primarily to workers' compensation
insurance companies, third party administrators, employers and employer groups.
We also market to the group health, automobile insurance and disability
insurance markets. Our marketing organization includes over 350 full-time sales
and marketing personnel, or their part-time equivalent.

      We market our services at both the local insurance company adjuster and
employer level. In addition, we market our services at the national and regional
level for large managed care accounts and for self-insured corporations where a
more sophisticated sales presentation is required. We have a dedicated staff of
national accounts salespeople responsible for marketing and coordinating our
full range of services to corporate offices.

      Our local marketing has been a critically important component of our
strategy, because of the decision-making authority that resides at the local
level and the relationship-driven nature of that portion of the business.
However, the expansion of comprehensive managed care legislation, continuing
receptiveness to workers' compensation change and a more comprehensive product
offering by us demand that we continue to focus on marketing to national
headquarters offices of insurance companies and self-insured companies. As part
of our coordinated marketing effort, we periodically distribute follow-up
questionnaires to patients, insurers and employers to monitor satisfaction with
our services.


QUALITY ASSURANCE

      We routinely use internal audits to test the quality of our delivery of
services. We conduct audits of compliance with special instructions, completion
of activities in a timely fashion, quality of reporting identification of
savings, accuracy of billing and professionalism in contacts with healthcare
providers. We conduct audits on a nationwide


                                       60
<PAGE>

basis for  particular  customers or on a local office basis by selecting  random
files for review.  A detailed  report is generated  outlining the audit findings
and providing specific  recommendations for service delivery improvements.  When
appropriate, we conduct follow-up audits to ensure that recommendations from the
initial audit have been implemented.


COMPETITION

HEALTHCARE SERVICES

      The market to provide healthcare services within the workers' compensation
system is highly fragmented and competitive. Our competitors typically have been
independent physicians, hospital emergency departments and other urgent care
providers. We believe that, as integrated networks continue to be developed, our
competitors will increasingly consist of specialized provider groups.

      We believe that we compete effectively because of:

      o    our specialization in the occupational healthcare industry;

      o    or broad knowledge and expertise;

      o    the effectiveness of our services as measured by favorable outcome;

      o    our ability to offer services in multiple markets; and

      o    our information systems.

      We believe that we enjoy a competitive advantage by specializing in and
focusing on occupational healthcare at the primary care provider level, which as
the entry point into the occupational healthcare system is well suited to
controlling the total costs of a claim. We do not believe that any other company
offers the full range of services we provide.

      The recruiting of physicians, physical therapists, nurses and other
healthcare providers can be competitive. However, our recruiting becomes easier
as we grow and become more widely known by healthcare providers.


SPECIALIZED COST CONTAINMENT AND FIELD CASE MANAGEMENT SERVICES

      The managed care services market is fragmented, with a large number of
competitors. We compete with numerous companies, including national managed care
providers, smaller independent providers, and insurance companies. Our primary
competitors are companies that offer one or more workers' compensation managed
care services on a national basis. We also compete with many smaller companies
that generally provide unbundled services on a national basis. We also compete
with many smaller companies that generally provide unbundled services on a local
level where such companies often have a relationship with a local adjuster.
Several large workers' compensation insurance carriers offer managed care
services for their insurance customers either through the insurance carrier's
own personnel or by outsourcing various services to providers such as us. We
believe that this competitive environment will continue into the foreseeable
future.

      We believe that we compete effectively because of:

      o    our specialized knowledge and expertise in the workers' compensation
           managed care services industry;

      o    the effectiveness of our services;

      o    our ability to offer a full range of services in multiple markets;


                                       61
<PAGE>

      o    our information systems; and

      o    the prices at which we offer our services.


INFORMATION SYSTEMS AND TECHNOLOGY

      We maintain a fundamental commitment to the development and implementation
of advanced information technology, with a considerable focus on web-based
applications. We believe that our information systems enable us to improve
referrals among our full range of services, streamline patient care and enhance
outcomes reporting. This makes our operations more efficient while improving our
ability to demonstrate the costs savings our services provide to our clients.

      We have substantially completed the implementation of a wide area network,
or WAN, in each market in which we provide healthcare services. When the
implementation is complete, all occupational healthcare centers in a market will
use a patient administration system, named "OccuSource," which runs on a
client/server architecture allowing each center to access and share a common
database for our market. The database contains employer protocols, patient
records and other information regarding our operations in the market. Creating a
WAN in each market allows the centers in the market to share information and
thereby improve center and physician efficiencies and enhance customer service.
We are linking each market WAN into a nationwide WAN in order to create a
centralized repository of company data to be used, among other things, for
clinical outcomes analysis. We believe that our commitment to continued
development of our healthcare information system provides a unique and
sustainable competitive advantage within the occupational healthcare industry.

      We have developed and, in the future, may license to third parties a new
internet-based first notice of loss reporting system for all lines of insurance,
named FNSNet. The application extends our call center technology through the
internet, enabling users to report first notices of loss, as well as providing
the user with immediate access to customized networks and routing to appropriate
and qualified healthcare providers. FNSNet can be accessed through hyperlinks on
customers' web pages. This application enhances both internal integration and
customer communication and creates an effective platform for our First Notice
subsidiary to handle calls with greater speed and efficiency.

      Our newly-developed Integrated Case Management Software System aids and
speeds up the daily tasks of our field and telephonic case managers, allowing
them to devote more time to consistent delivery of quality service. This
software allows immediate exchange of information among our offices, as well as
among employees in the same office. The Integrated Case Management Software
System is integrated with the FNSNet web-based product. The Integrated Case
Management Software System application enables a clear, precise and immediate
transmission of data from First Notice into the Integrated Case Management
Software System. This pre-population of data eliminates redundant and
duplicative data entry for nurse case managers, thus resulting in greater time
efficiency and cost savings. The development and implementation of the
Integrated Case Management Software System allow for shared data in situations
in which multiple case managers are working on a case. The Integrated Case
Management Software System also creates better customer access to information
and allows us to produce specific, user-friendly reports to demonstrate the
value of our services.

      Finally, our subsidiary, Concentra Preferred Systems, uses our
proprietary, technology-based Healthcare Bill Management System for our
out-of-network medical claims review services. Client bills are accessed and
entered into the Healthcare Bill Management System in a variety of ways,
including electronic bill identification within the client's claim adjudication
system with subsequent EDI transfer to Concentra Preferred Systems, entry of
appropriate bills into a customized, Data Access Point system, on-site bill
entry by a Concentra Preferred Systems employee into the Data Access Point
system, and overnight mail or facsimile of client bills to a Concentra Preferred
Systems service center. These access strategies are designed to increase the
number of appropriate bills that Concentra Preferred Systems receives, while
minimizing the administrative cost to the client. Once a bill is electronically
or manually entered into the Healthcare Bill Management System, the bill is
evaluated against Concentra Preferred Systems licensed and proprietary databases
that are designed to identify instances of cost shifting, improper coding and
utilization and pricing issues. Following analysis of the bill, the bill passes
through Concentra Preferred System's client


                                       62
<PAGE>

preference  profile that is created at the time of Concentra  Preferred  Systems
initial  engagement with the client.  The Healthcare Bill Management System then
evaluates the  compatibility  of the service with the greatest  expected savings
with the service  requirements of the client and  electronically  sends the bill
for  processing  to  the  appropriate   Concentra   Preferred   Systems  service
department.


GOVERNMENT REGULATION

GENERAL

      As a provider of healthcare management and cost containment services, we
are subject to extensive and increasing regulation by a number of governmental
entities at the federal, state and local levels. We are also subject to laws and
regulations relating to business corporations in general. Applicable laws and
regulations are subject to frequent changes.

      Laws and regulations affecting our operations fall into four general
categories:

      o    workers' compensation and other laws that regulate the provision of
           healthcare services or the provision of cost containment services or
           require licensing, certification or other approval of services we
           provide;

      o    laws regarding the provision of healthcare services generally;

      o    laws regulating the operation of managed care provider networks; and

      o    other laws and regulations of general applicability.


WORKERS' COMPENSATION LAWS AND REGULATIONS

      In performing workers' compensation healthcare services and cost
containment services, we must comply with state workers' compensation laws.
Workers' compensation laws require employers to assume financial responsibility
for medical costs, a portion of lost wages and related legal costs of
work-related illnesses and injuries. These laws establish the rights of workers
to receive benefits and to appeal benefit denials. Workers' compensation laws
generally prohibit charging medical co-payments or deductibles to employees. In
addition, certain states restrict employers' rights to select healthcare
providers and establish maximum fee levels for treatment of injured workers.

      Many states are considering or have enacted legislation reforming their
workers' compensation laws. These reforms generally give employers greater
control over who will provide healthcare services to their employees and where
those services will be provided and attempt to contain medical costs associated
with workers' compensation claims. At present, 24 of the states in which we do
business have implemented treatment specific fee schedules that set maximum
reimbursement levels for healthcare services. The District of Columbia and 10
states provide for a "reasonableness" review of medical costs paid or reimbursed
by workers' compensation. When not governed by a fee schedule, we adjust our
charges to the usual, customary and reasonable levels accepted by the payor.

      Many states, including a number of those in which we transact business,
have licensing, and other regulatory requirements that apply to our specialized
cost containment and field case management business. Approximately half of the
states have enacted laws that require licensing of businesses that provide
medical review services, such as ours. Some of these laws apply to medical
review of care covered by workers' compensation. These laws typically establish
minimum standards for qualifications of personnel, confidentiality, internal
quality control and dispute resolution procedures. In addition, new laws
regulating the operation of managed care provider networks have been adopted by
a number of states. These laws may apply to managed care provider networks
having contracts with us or to provider networks that we have organized and may
organize in the future. To the extent that we are governed by these regulations,
we may be subject to additional licensing requirements, financial oversight and
procedural standards for beneficiaries and providers.


                                       63

CORPORATE PRACTICE OF MEDICINE AND OTHER LAWS

      Most states limit the practice of medicine to licensed individuals or
professional organizations comprised of licensed individuals. Many states also
limit the scope of business relationships between business entities such as ours
and licensed professionals and professional corporations, particularly with
respect to fee-splitting between physicians and non-physicians. Laws and
regulations relating to the practice of medicine, fee-splitting and similar
issues vary widely from state to state, are often vague, and are seldom
interpreted by courts or regulatory agencies in a manner that provides guidance
with respect to business operations such as ours. We attempt to structure all of
our healthcare services operations to comply with applicable state statutes
regarding medical practice, fee-splitting and similar issues. However, there can
be no assurance:

      o    that courts or governmental officials with the power to interpret or
           enforce these laws and regulations will not assert that we are in
           violation of such laws and regulations; or

      o    that future interpretations of such laws and regulations will not
           require us to modify the structure and organization of our business.


FRAUD AND ABUSE LAWS

      The Anti-Kickback Statute prohibits the offer, payment, solicitation or
receipt of any form of remuneration to induce or in return for the referral of
Medicare or other governmental health program patients or patient care
opportunities, or in return for the purchase, lease or order of items or
services that are covered by Medicare or other governmental health programs.
Violations of the statute can result in the imposition of substantial civil and
criminal penalties. In addition, as of January 1, 1995, certain anti-referral
provisions, the Stark Amendments, prohibit a physician with a "financial
relationship" with an entity from referring a patient to that entity for the
provision of any of 11 "designated medical services", some of which are provided
by physician groups affiliated with us.

      At least seven of the states where we conduct our healthcare services
business-Arizona, California, Florida, Illinois, Maryland, New Jersey, and
Texas-have enacted statutes similar in scope and purpose to the Anti-Kickback
Statute, with applicability to services other than those covered by Medicare or
other governmental health programs. In addition, most states have statutes,
regulations or professional codes that restrict a physician from accepting
various kinds of remuneration in exchange for making referrals. Even in states
which have not enacted such statutes, we believe that regulatory authorities and
state courts interpreting these statutes may regard federal law under the
Anti-Kickback Statute and the Stark Amendments as persuasive.

      We believe that our arrangements with the physician groups should not
violate the Anti-Kickback Statute, the Stark Amendments and applicable state
laws. However, all of the above laws are subject to modification and
interpretation and have not often been interpreted by appropriate authorities in
a manner applicable to our business. Moreover, these laws are enforced by
authorities vested with broad discretion. We have attempted to structure all of
our operations so that they should not violate any applicable anti-kickback and
anti-referral prohibitions. We also continually monitor developments in this
area. If these laws are interpreted in a manner contrary to our interpretation
or are reinterpreted or amended, or if new legislation is enacted with respect
to healthcare fraud and abuse, illegal remuneration or similar issues, we will
seek to restructure any affected operations to maintain our compliance with
applicable law. We cannot assure you that such restructuring will be possible,
or, if possible, will not adversely affect our business or results of
operations.


SPECIALIZED COST CONTAINMENT SERVICES

      Many of our specialized cost containment services include prospective or
concurrent review of requests for medical care or therapy. Approximately half of
the states have enacted laws that require licensure, certification or other
approval of businesses, such as ours, that provide medical review services. Some
of these laws apply to medical review of care covered by workers' compensation.
These laws typically establish minimum standards for qualifications of
personnel, confidentiality, internal quality control and dispute resolution
procedures. These regulatory


                                       64
<PAGE>

programs  may result in increased  costs of operation  for us, which may have an
adverse impact upon our ability to compete with other available alternatives for
healthcare cost control.


USE OF PROVIDER NETWORKS

      Our ability to provide comprehensive healthcare management and cost
containment services depends in part on our ability to contract with or create
networks of healthcare providers which share our objectives. For some of our
clients, we offer injured workers access to networks of providers who are
selected by us for quality of care and pricing. Laws regulating the operation of
managed care provider networks have been adopted by a number of states. These
laws may apply to managed care provider networks having contracts with us or to
provider networks that we may develop or acquire. To the extent these
regulations apply to us, we may be subject to:

      o    additional licensing;

      o    requirements;

      o    financial oversight; and

      o    procedural standards for beneficiaries and providers.


ERISA

      The provision of goods and services to certain types of employee health
benefit plans is subject to the Employee Retirement Income Security Act of 1974,
or ERISA. ERISA is a complex set of laws and regulations subject to periodic
interpretation by the Internal Revenue Service and the Department of Labor.
ERISA regulates certain aspects of the relationship between our managed care
contracts and employers that maintain employee benefit plans subject to ERISA.
The Department of Labor is engaged in ongoing ERISA enforcement activities that
may result in additional constraints on how ERISA-governed benefit plans conduct
their activities. We cannot assure you that future revisions to ERISA or
judicial or regulatory interpretations of ERISA will not have a material adverse
effect on our business or results of operations.


ENVIRONMENTAL

      We are subject to various federal, state and local laws and regulations
for the protection of human health and environment, including the disposal of
infectious medical waste and other waste generated at our occupational
healthcare centers. If an environmental regulatory agency finds any of our
centers to be in violation of environmental laws, penalties and fines may be
imposed for each day of violation, and the affected facility could be forced to
cease operations. While we believe that our environmental practices, including
waste handling and discharge practices, are in material compliance with
applicable law, future claims or changes in environmental laws could have an
adverse effect on our business.


SEASONALITY

      Our healthcare services business is seasonal in nature. Although our
expansion of services and continuing growth may obscure the effect of
seasonality in our financial results, our first and fourth quarters generally
reflect lower net healthcare services revenues on a same market basis when
compared to the second and third quarters.

      Plant closings, vacations and holidays during the first and fourth
quarters result in fewer patient visits at our occupational healthcare centers,
primarily because of fewer occupational injuries and illnesses during those
periods. In addition, employers generally hire fewer employees during the fourth
quarter, thereby reducing the number of pre-employment physical examinations and
drug and alcohol tests conducted at our centers during that quarter. See
"Management's Discussion and Analysis of Financial Conditions and Results of
Operations--Seasonality."

INSURANCE

      We and our physician groups maintain medical malpractice insurance in the
amount of $1.0 million per incident/$3.0 million annual aggregate per provider,
subject to an annual aggregate limit in the amount of $20.0 million. Pursuant to
the management agreements between us and the physician groups, each physician
group has agreed to indemnify us from certain losses, including medical
malpractice. We maintain an errors and omissions liability insurance policy
covering all aspects of our managed care services. This policy has limits of
$1.0 million per claim/$3.0 million annual aggregate.

      In addition, we maintain $3.0 million of general liability insurance and
an umbrella policy that provides excess insurance coverage for medical
malpractice and for errors and omissions in the amount of $30.0 million per
occurrence and $30.0 million in the aggregate.


EMPLOYEES

      We had approximately 8,800 employees at November 1, 1999. None of our
employees is subject to a collective bargaining agreement. We have experienced
no work stoppages and believe that our employee relations are good. All
physicians, physician assistants and physical therapists providing professional
services in our occupational healthcare centers are either employed by or under
contract with the physician groups.


PROPERTIES

      Our principal corporate office is located in Boston, Massachusetts. We
lease the 11,000 square feet of space in this site pursuant to a lease agreement
expiring in 2003. We make annual rental payments under that lease of $396,000.
Except for 12 properties owned by us, we lease all of our offices located in 49
states, the District of Columbia and Canada. Twelve of our offices are leased
from Colonial Realty Trust, of which Lois E. Silverman, a former director of
Concentra, is a trustee and beneficiary. We believe that our facilities are
adequate for our current needs and that suitable additional space will be
available as required.

THE BOARD OF DIRECTORS

CORPORATE GOVERNANCE

      Pursuant to the Delaware General Corporation Law, as implemented by
Concentra's Certificate of Incorporation and Bylaws, the business, property and
affairs of Concentra are managed under the direction of a board of directors.
Members of this board are kept informed of the Concentra's business through
discussions with the Chairman, the President and other officers, by reviewing
materials provided to them and by participating in meetings of the board and its
committees.

      During 1998, the board of directors held a total of 13 meetings, including
4 regular meetings and 9 special meetings. Each director attended more than 75%
of the aggregate of (1) the total number of meetings held by the board and (2)
the total number of meetings held by all committees of the board on which he
served.


COMMITTEES OF THE BOARD OF DIRECTORS

      During 1998, the board of directors of Concentra had two standing
committees: an Audit Committee, now known as the Audit and Compliance Committee
and an Option and Compensation Committee, now known as the Compensation
Committee.

      The Audit Committee held two meetings in 1998. The Audit Committee reviews
the adequacy of Concentra's system of internal controls and accounting
practices. In addition, the Audit Committee reviews the scope of the annual
audit of Concentra's independent public accountants, Arthur Anderson LLP, prior
to its commencement, and reviews the types of services for which Concentra
retains Arthur Anderson LLP. Commencing in December 1998, the board of directors
designated the Audit Committee as the committee charged with primary oversight
of Concentra's Corporate Integrity Program, currently under development.


                                       68
<PAGE>

      The Option and Compensation Committee held six meetings in 1998. The
functions of the Option and Compensation Committee are to establish annual
salary levels, approve fringe benefits and administer any special compensation
plans or programs for officers of Concentra, review and approve the salary
administration program for Concentra and administer Concentra's incentive and
stock option plans.

     During the fiscal year ended  December 31, 1998, the members of the Audit
Committee were Willis D. Gradison, Jr., Mitchell T. Rabkin, M.D. and Lois E.
Silverman. Currently, D.Scott Mackesy, Steven E. Nelson and John K. Carlyle
serve on the Audit and Compliance Committee.

     During the fiscal year ended  December 31, 1998, the members of the Option
and Compensation  Committee were John K. Carlyle, George H. Conrades and Robert
A. Ortenzio. Currently, John K. Carlyle, Carlos Ferrer, Paul B. Queally and
Andrew M. Paul serve on the Compensation Committee.


COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     Messrs.  Paul and Queally are managing  members of the sole general partner
of Welsh Carson. Because of these affiliations,  Messrs. Paul and Queally may be
deemed to have a material  interest  in the  matters  described  under  "Certain
Relationships and Related Transactions--Equity Investor Agreements."


COMPENSATION OF DIRECTORS

      CONCENTRA OPERATING. None of the directors of Concentra Operating will
receive any remuneration from Concentra Operating for their attendance at board
and committee meetings during 1999.

      CONCENTRA. During 1998, each director who was not also an employee of
Concentra automatically received options for 5,000 shares of Concentra common
stock and restricted stock valued at $15,000 under Concentra's 1997 Long-Term
Incentive Plan to each director who was not an employee on the date of each
annual meeting of Concentra stockholders. During such period, Concentra
directors who were also employees of Concentra received no remuneration for
attendance at board and committee meetings.

      Concentra directors who are not employees receive compensation that is in
accordance with the Welsh Carson's customary practices and consistent with
compensation paid to directors in comparable public companies.

(5)   Excludes payments totaling $1,354,092 paid to Mr. Larson in connection
      with his resignation from Concentra as its Chairman, President and Chief
      Executive Officer in September of 1997 comprised of salary continuation
      payments of $1,150,000, transfer of the cash surrender value of a
      split-dollar life insurance policy of $168,592, consulting fees of $25,000
      and other benefits of $10,500. Concentra is further obligated to pay Mr.
      Larson an additional $125,000 under his consulting agreement in 1999.


OPTION AND RESTRICTED STOCK GRANTS

      The named executive officers and other key executives of Concentra were
granted new options to acquire up to 10.5% of Concentra common stock following
the merger at a price per share equal to $16.50 under Concentra's 1999 Stock
Option and Restricted Stock Purchase Plan. Some of these new options are
non-qualified and vest 20% per year over a five year period; other options vest
upon the achievement of certain performance criteria.

      The following tables set forth certain information concerning grants by
Concentra of stock options and restricted stock to each of the named executive
officers during 1998. In accordance with the rules of the Commission, the
potential realizable values under such options are shown based on assumed rates
of annual compound stock price appreciation of 5% and 10% over the full option
term from the date the option was granted.

EMPLOYMENT AGREEMENTS

      Each of Daniel J. Thomas, Thomas A. Kiraly, James M. Greenwood, Richard A.
Parr II, and W. Tom Fogarty, M.D. have entered into employment agreements
between such individuals and Concentra. The principal terms of these employment
agreements are as follows:

      o    each agreement has a term of two years, subject to automatic renewal
           for additional one-year terms, unless terminated in accordance with
           the agreement's terms;

      o    each agreement provides for compensation consisting of base salary
           amounts, bonuses at the discretion of the board of directors of
           Concentra and participation in any employee benefit plan adopted by
           us for our employees;

      o    each agreement provides for a severance payment in the event of (1)
           termination by Concentra without cause, or (2) resignation by the
           employee for good reason; consisting of two years' base salary for
           Mr. Thomas and one year's base salary for Messrs. Greenwood, Kiraly,
           Parr and Fogarty; provided, however, if termination by Concentra
           occurs on or before August 17, 2000, each agreement provides for a
           severance payment consisting of two and half year's base salary for
           Mr. Thomas and two years' base salary for each of Messrs. Greenwood,
           Kiraly, Parr, and Fogarty.


OFFICERS' AND DIRECTORS' INDEMNIFICATION INSURANCE

      The merger agreement provides that, for a period of six years after the
effective time, Concentra will indemnify the present and former officers,
directors, employees and agents of Concentra and its subsidiaries from
liabilities arising out of actions or omissions in that capacity prior to the
effective time of the merger, to the full extent permitted under Delaware law or
as provided in Concentra's or its subsidiaries' organization documents or any
written indemnification agreements. In addition, the surviving entity will
maintain directors' and officers' insurance coverage for six years after the
effective time on terms no less favorable to such indemnified parties than
existing insurance coverage, but Concentra will not be required to pay an annual
premium in excess of 200% of the last premium paid prior to the date of the
merger agreement.


EMPLOYEE BENEFIT PLANS

1999 LONG-TERM INCENTIVE PLAN


GENERAL

      Concentra's board and stockholders approved its 1999 Stock Option and
Restricted Stock Purchase Plan in August 1999. The purpose of the 1999 Stock
Plan is to promote the interests of Concentra and its subsidiaries and the
interests of our stockholders by providing an opportunity to selected employees
and officers of Concentra and its subsidiaries and to other persons providing
services to Concentra and its subsidiaries to purchase Concentra common stock.
By encouraging such stock ownership, we seek to attract, retain and motivate
such employees and other persons and to encourage such employees and other
persons to devote their best efforts to our business and financial success.
Under the 1999 Stock Plan, we may grant incentive stock options and non
qualified stock options and restricted stock purchase awards to purchase an
aggregate of up to 3,750,000 shares of Concentra common stock. The following
summary describes the principal features of the 1999 Stock Plan and is qualified
in its entirety by reference to the specific provisions of the 1999 Stock Plan,
which is filed as an exhibit to the registration statement of which this
prospectus forms in part.


DESCRIPTION OF 1999 STOCK PLAN

      SHARES AND OPTIONS SUBJECT TO PLAN. The 1999 Stock Plan provides for the
grant of options or awards to purchase an aggregate 3,750,000 shares of common
stock, either in the form of incentive stock options intended to meet the
requirements of Section 422 of the Code or nonqualified stock options or
restricted stock purchase awards. The 1999 Stock Plan includes provisions for
adjustment of the number of shares of common stock available for grant of


                                       73
<PAGE>

award thereunder and in the number of shares of common stock underlying
outstanding options in the event of any stock splits, stock dividends or other
relevant changes in the capitalization of Concentra.

      ELIGIBILITY. Under the 1999 Stock Plan, employees, including officers, are
eligible to receive grants of either incentive stock options structures to
qualify under Section 422 of the Code, or nonqualified stock options and
restricted stock purchase awards, both of which are not intended to meet the
requirements of Code Section 422. Non-employee directors are eligible to be
granted only nonqualified options and awards.

      ADMINISTRATION. Administration of the 1999 Stock Plan has been delegated
to the Compensation Committee, consisting entirely of "Non-Employee Directors"
within the meaning of the Exchange Act, and "outside directors" within the
meaning of the Code. The Compensation Committee, within the parameters of the
1999 Stock Plan, has authority to determine to whom options and awards are
granted. All questions of interpretation or application of the 1999 Stock Plan
are determined by the Compensation Committee, whose decisions are final and
binding upon all participants.

      TERMS OF OPTIONS AND AWARDS. Each option or award granted will be
evidenced by a stock option or restricted stock purchase agreement.

      The Compensation Committee will fix the term and vesting provisions of all
options granted pursuant to the 1999 Stock Plan.

      The exercise price of incentive stock options may not be less than 100% of
the fair market value of the shares of common stock, as determined by the board
or the Compensation Committee, as the case may be, on the date the option is
granted. The exercise price of non-qualified stock options may not be less than
100% of the fair market value of the shares of common stock on the date the
option is granted. In addition, the aggregate fair market value of the shares of
stock with respect to which incentive stock options are exercisable for the
first time by an optionee during any calendar year shall not exceed $100,000. In
addition, no incentive stock option shall be granted to an optionee who owns
more than 10% of the total combined voting power for all classes of stock of
Concentra, unless the exercise price is at least 110% of the fair market value
of the shares of common stock and the exercise period does not exceed 5 years.

      Restricted stock purchase awards granted under the 1999 Stock Plan will be
in such amounts and at such times as determined by the Compensation Committee.
The purchase price, as well as the vesting provisions, of such awards shall be
determined by the Compensation Committee and the purchase price may be equal to,
less than or more than the fair market value of the shares of common stock to be
awarded.

      TERM OF THE 1999 STOCK PLAN. The 1999 Stock Plan will continue in effect
until August 17, 2009 unless terminated prior to such date by the board.


CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE 1999 STOCK PLAN

      The tax consequences of incentive stock options, non-qualified stock
options and restricted stock purchase awards are quite complex. Therefore, the
description of tax consequences set forth below is necessarily general in nature
and does not purport to be complete. Moreover, statutory provisions are subject
to change, as are their interpretations, and their application may vary in
individual circumstances. Finally, the tax consequences under applicable state
and local income tax laws may not be the same as under the federal income tax
laws.

      Incentive stock options granted pursuant to the 1999 Stock Plan are
intended to qualify as "incentive stock options" within the meaning of Section
422 of the Code. If an optionee does not dispose of the shares acquired pursuant
to exercise of an incentive stock option within one year after the transfer of
such shares to the optionee and within two years from grant of the option such
optionee will recognize no taxable income as a result of the grant or exercise
of such option. However, for alternative minimum tax purposes the optionee will
recognize as an item of tax preference the difference between the fair market
value of the shares received upon exercise and the exercise price. Any gain or
loss that is subsequently recognized upon a sale or exchange of the shares may
be treated by the optionee as long-term capital gain or loss, as the case may
be. Concentra will not be entitled to a deduction for fed-


                                       74
<PAGE>

eral income tax purposes with respect to the issuance of an incentive stock
option, the transfer of shares upon exercise of the option of the ultimate
disposition of such shares provided the holding period requirements are
satisfied.

      If shares received upon exercise of an incentive stock option are disposed
or prior to satisfaction of the holding period requirements, the optionee
generally will recognize taxable ordinary income, in the year in which such
disqualifying disposition occurs, in an amount equal to the lesser of (1) the
excess of the fair market value of the shares on the date of exercise over the
exercise price, and (2) the gain recognized on such disposition. Such amount
will ordinarily be deductible by Concentra for federal income tax purposes in
the same year, provided that the company satisfies certain federal income tax
information reporting requirements. In addition, the excess, if any, of the
amount realized by the exercise of the incentive stock option will be treated as
capital gain, long-term or short-term, depending on whether, after exercise of
the option, the shares were held for more than one year.

      Non-qualified stock options may be granted under the 1999 Stock Plan. An
optionee generally will not recognize any taxable income upon grant of a
non-qualified stock option. The optionee will recognize taxable ordinary income,
at the time of exercise of such option, in an amount equal to the excess of the
fair market value of the shares on the date of exercise over the exercise price.
Such amount will ordinary be deductible by Concentra in the same year, provided
that Concentra satisfies certain federal income tax information reporting
requirements. Any gain or loss that is subsequently recognized by the optionee
upon a sale or exchange of the shares will be capital gain or loss, long-term or
short-term, depending on whether, after the exercise of the option, the shares
were held for more than one year prior to such sale or exchange.

      Restricted stock purchase awards may also be granted pursuant to the 1999
Stock Plan. A recipient of a restricted stock purchase award generally will not
recognize taxable income upon the purchase of shares of restricted stock, unless
he or she makes a timely election under Section 83(b) of the Code. Such a
recipient, however, would recognize taxable ordinary income and the holding
period for such shares would commence at the time that such shares become
vested, in amount equal to the excess of the fair market value of the shares at
the time over the purchase price paid for such shares. If, on the other hand,
the recipient makes a timely election under Section 83(b), he or she would
recognize taxable ordinary income and the holding period for such shares would
commence at the time of purchase, in an amount equal to the excess of the fair
market value of the shares at that time, determined without regard to any
transfer restrictions imposed on the shares, vesting provisions or any
restrictions imposes by the securities laws, over the purchase price paid for
such shares. In either case, Concentra should be entitled to a deduction in an
amount equal to the ordinary income recognized by the recipient in the same year
that the recipient recognized such income, provided that the company satisfies
certain federal income tax information reporting requirements. Any gain or loss
that is subsequently recognized by the recipient upon a sale or exchange of the
shares will be capital gain or loss, long-term or short-term, depending on
whether the shares were held for more than one year prior to such sale or
exchange.


 401(K) PLAN

      Concentra has a defined contribution retirement plan which complies with
Section 401(k) of the Internal Revenue Code. Substantially all employees of
Concentra, including certain officers and directors of Concentra, who have
completed six months of service are eligible to participate in the Concentra
Managed Care, Inc. 401(k) Plan. Generally, employees may contribute amounts up
to a maximum of 15% of the employee's compensation. Under the plan, Concentra
has the option of matching up to 50% of the participants' pretax contributions
up to a maximum of 6% of compensation. For fiscal year 1998, Concentra elected
to match 50% of up to 4% of compensation.


EMPLOYEE STOCK PURCHASE PLAN

      Until March 2, 1999, Concentra maintained an Employee Stock Purchase Plan
that permitted substantially all employees to acquire Concentra common stock at
the end of each specified period at a purchase price of 85% of the lower of the
fair market value at the end of the participation period. Periods were
semi-annual and began on January 1 and July 1 of each year. Employees were
allowed to designate up to 15% of their base compensation for the purchase of
common stock. The Option and Compensation Committee administered the Employee
Stock Purchase Plan. On March 2, 1999, Concentra terminated the Employee Stock
Purchase Plan. The final period for which participating employees acquired
shares of Concentra's common stock began on January 1, 1999 and ended March 2,
1999.

EQUITY INVESTOR AGREEMENTS

      PURCHASE AGREEMENT

      In connection with its investment in Yankee, Ferrer Freeman entered into a
subscription agreement to purchase 1,854,545 shares of Yankee's Class A common
stock immediately prior to the merger, representing approximately 7% of Yankee's
outstanding capital stock. The Class A common stock of Yankee is identical in
all respects to Yankee's common stock except that the holders of Class A common
stock are entitled to elect one member to Yankee's board of directors. In the
merger, these shares of Yankee's Class A common stock were converted into an
equal number of shares of Class A common stock of Concentra with the same rights
as Yankee's Class A common stock prior to the merger.

      In connection with their investment in Yankee, the Welsh Carson investors
and the other investors entered into a subscription agreement to purchase
23,821,953 shares of Yankee's common stock immediately prior to the merger,
representing approximately 93% of Yankee's outstanding capital stock. In the
merger, these shares of Yankee's common stock were converted into an equal
number of shares of Concentra common stock with the same rights as Yankee's
common stock prior to the merger.


      STOCKHOLDERS AGREEMENT

      The Welsh Carson investors, the other investors, Ferrer Freeman and
Concentra also entered into a stockholders agreement. The stockholders agreement
does not provide for any agreements with the Welsh Carson investors, the other
investors, and Ferrer Freeman with respect to voting of shares or management of
Concentra. The stockholders agreement provides for:

      o    limitations on the transfer of shares owned by the investors;

      o    tag along rights for Ferrer Freeman, the other investors, and the
           Welsh Carson investors, other than Welsh Carson, to participate in
           proposed dispositions of Concentra common stock by Welsh Carson;

      o    in the event that Welsh Carson receives a third party offer to
           purchase a significant portion of the outstanding Concentra common
           stock, Welsh Carson may require Ferrer Freeman, the Welsh Carson
           investors and the other investors to accept the offer and sell their
           shares of Concentra to the third party; and


                                       78

           basis according to their ownership of Concentra capital stock, in
           equity offerings of Concentra with certain customary exceptions.


      REGISTRATION RIGHTS AGREEMENT

      At the same time they executed the stockholders agreement, the Welsh
Carson investors, the other investors, Ferrer Freeman and Concentra entered into
a registration rights agreement. The registration rights agreement gives the
investors rights to require Concentra to register their shares of Concentra
capital stock under the Securities Act and to include, upon request, their
shares in any other registration of shares by Concentra.

        material provisions of those documents, the guarantees, security
        documents or any related documents to be enforceable and in full force
        and effect;

     o  certain change of control events;

     o  the conduct of Concentra's business; and

     o  the failure of the subordination of the notes and the subsidiary
        guarantees to the right of payment of the lenders under the senior
        credit facilities to be valid.


THE DISCOUNT DEBENTURES

     Concentra raised approximately $110.0 million of the funds necessary to
consummate the transactions through the issuance of the discount debentures in
the private capital markets. The discount debentures were issued with warrants
to purchase 5.85% of Concentra common stock at a nominal exercise price.
Concentra is not required to pay any interest on the discount debentures until
2004. The discount debentures:

     o  mature on August 15, 2010;

     o  are structurally subordinated to the senior credit facilities and the
        notes;


                                       82
<PAGE>


     o  have registration rights;

     o  are redeemable by Concentra after August 15, 2000;

     o  are redeemable by Concentra at the option of the holders upon a change
        of control; and

     o  subject Concentra and its subsidiaries to customary covenants for this
        type of financing, including restrictions on indebtedness, dividends,
        liens, affiliate transactions, stock repurchases, assets sales and
        mergers.

     In addition, the discount debentures bear non-cash interest at a rate of
14% per annum until August 15, 2004. On February 15, 2005, and on subsequent
interest payment dates, Concentra will also pay to the holders of the discount
debentures that amount that is necessary to ensure the current and full tax
deductibility of the accrued discount on the discount debentures. That initial
amount is expected to be approximately $95.0 million. Subsequent amounts are not
expected to be material. The indenture with respect to the notes provides that
all such payments by Concentra will not be payments of cash interest for
purposes of clause (10) of the second paragraph under "Description of
Notes--Certain Covenants--Restricted Payments." If Concentra is unable to make
such payment, there will not be an event of default under the discount
debentures indenture, rather the interest rate on the discount debentures will
increase by 100 basis points until such payment is made. After August 15, 2004,
interest at the rate of 14% per annum will be payable semi-annually in cash on
the discount debentures.

                          DESCRIPTION OF THE NEW NOTES

     The old notes were, and the new notes will be, issued under an indenture
dated August 17, 1999 among Concentra Operating, Health Services and Managed
Care Services, and United States Trust Company of New York, as trustee.

     The new notes are the same as the old notes except that the new notes will:

     o  have a new CUSIP number;

     o  not bear any legends restricting their transfer; and

     o  not contain certain terms providing for an increase in the interest rate
        under the circumstances described in the registration rights agreement.

     The following description is a summary of the material provisions of the
indenture. It does not restate that agreement in its entirety. We urge you to
read the indenture because it, and not this description, define your rights as
holders of these notes.

     In this description of the new notes, we use terms in this section that are
defined under the caption "--Certain Definitions."


BRIEF DESCRIPTION OF THE NOTES AND THE SUBSIDIARY GUARANTEES

     THE NOTES. The notes are:

     o  general unsecured obligations of Concentra Operating;

     o  subordinated in right of payment to all existing and future Senior
        Indebtedness of Concentra Operating;

     o  senior or pari passu in right of payment to all existing and future
        subordinated Indebtedness of Concentra Operating; and

     o  unconditionally guaranteed by the Guarantors.


                                       83
<PAGE>


     THE SUBSIDIARY GUARANTEES. These notes are jointly and severally guaranteed
by each Restricted Subsidiary of Concentra Operating, except the Permitted Joint
Ventures.

     The Subsidiary Guarantees of these notes:

     o  are general unsecured obligations of each Guarantor;

     o  are subordinated in right of payment to all existing and future Senior
        Indebtedness of each Guarantor; and

     o  are senior or PARI PASSU in right of payment to all existing and future
        subordinated Indebtedness of each Guarantor.

     Assuming Concentra Operating had completed the offering of the old notes,
applied the net proceeds as intended and had completed the merger with Yankee
and related transactions as of June 30, 1999, Concentra Operating and the
Guarantors would have had total Senior Indebtedness of approximately $379.0
million. As indicated above and as discussed in detail below under the caption
"--Subordination," payments on the notes and under the Subsidiary Guarantees
will be subordinated to the payment of Senior Indebtedness. The indenture will
permit Concentra Operating and the Guarantors to incur additional Senior
Indebtedness.

     As of August 17, 1999, all of Concentra Operating's Subsidiaries were
"Restricted Subsidiaries." However, under the circumstances described below
under the caption "--Certain Covenants--Designation of Restricted and
Unrestricted Subsidiaries," Concentra Operating will be permitted to designate
certain of Concentra Operating's subsidiaries as "Unrestricted Subsidiaries."
Unrestricted Subsidiaries will not be subject to many of the restrictive
covenants in the indenture. Unrestricted Subsidiaries will not guarantee the
notes.


PRINCIPAL, MATURITY AND INTEREST

     The notes:

     o  will be limited to a maximum aggregate principal amount of $190.0
        million;

     o  will mature on August 15, 2009;

     o  will be issued in denominations of $1,000 and integral multiples of
        $1,000;

     o  will bear interest at the rate of 13% per annum.

     Interest will be paid semi-annually on February 15 and August 15 of each
year, beginning on February 15, 2000, to the holder of record on the immediately
preceding February 1 and August 1.

     Interest will be computed on the basis of a 360-day year comprised of
twelve 30-day months.


METHODS OF RECEIVING PAYMENTS ON THE NOTES

     If a holder has given wire transfer instructions to Concentra Operating,
Concentra Operating will make all principal, premium and interest payments on
the holder's notes in accordance with those instructions. All other payments on
the notes will be made at the office or agency of the paying agent and registrar
within the City and State of New York unless Concentra Operating elects to make
interest payments by check mailed to the holders at their address set forth in
the register of holders.


SUBORDINATION

     The payment of principal of, any premium and interest on the notes will be
subordinated to the prior payment in full of all Concentra Operating's Senior
Indebtedness.


                                       84
<PAGE>


     The holders of Senior Indebtedness will be entitled to receive payment in
full in cash of all amounts due or to become due in respect of Senior
Indebtedness before the holders of notes will be entitled to receive any payment
with respect to the notes, except that holders of notes may receive
Reorganization Securities and payments made from the trust described under the
caption "--Legal Defeasance and Covenant Defeasance," in the event of any
distribution to Concentra Operating's creditors pursuant to any Insolvency or
Liquidation Proceeding with respect to Concentra Operating.

     Upon any such Insolvency or Liquidation Proceeding, any payment or
distribution of assets of Concentra Operating of any kind, other than
Reorganization Securities, will be paid by Concentra Operating or by any
receiver, liquidating trustee or other person making such payment or
distribution, or by the holders of the notes or by the trustee if received by
them, directly to the holders of Senior Indebtedness, or their representative or
representatives, for the payment of the Senior Indebtedness until all such
Senior Indebtedness has been paid in full in cash.

     Concentra Operating also may not make any payment in respect of the notes,
except in Reorganization Securities, if:

     o    a payment default on Designated Senior Indebtedness occurs and is
          continuing; or

     o    the trustee receives a notice from the agent bank under one of
          Concentra Operating's senior credit facilities or the holders or the
          representative of any Designated Senior Indebtedness indicating that a
          default has occurred that permits the holders of that indebtedness to
          accelerate its maturity.

     Payments on the notes may and will be resumed:

     o    in the case of a payment default, upon the date on which such default
          is cured or waived; and

     o    in case of a nonpayment default, the earlier of

          (1)  the date on which such nonpayment default is cured or waived;

          (2)  179 days after the date on which the applicable notice is
               received; or

          (3)  the date on which the trustee receives written notice from the
               agent bank or the representative for such Designated Senior
               Indebtedness, as the case may be, rescinding the applicable
               notice, unless the maturity of any Designated Senior Indebtedness
               has been accelerated.

     No new notice of default may be delivered unless and until 181 days have
elapsed since the effectiveness of the immediately prior notice.

     No event of default that existed or was continuing on the date of delivery
of any such notice to the trustee shall be, or be made, the basis for a
subsequent notice unless such default shall have been cured or waived for a
period of not less than 90 days.

     As a result of the subordination provisions described above, in the event
of a bankruptcy, liquidation or reorganization of Concentra Operating, holders
of these notes may recover less ratably than creditors of Concentra Operating
who are holders of Senior Indebtedness. See "Risk Factors--Risks Applicable to
the Notes--Subordination." Concentra Operating and its Restricted Subsidiaries
will be subject to certain financial tests limiting the amount of additional
Indebtedness, including Senior Indebtedness, that Concentra Operating and its
Restricted Subsidiaries can incur. See "--Certain Covenants--Incurrence of
Indebtedness and Issuance of Preferred Stock."


SUBSIDIARY GUARANTEES

     The Guarantors will jointly and severally guarantee, on a senior
subordinated basis, Concentra Operating's obligations under the notes. Each
Subsidiary Guarantee will be subordinated to the prior payment in full of all


                                       85
<PAGE>


Senior Indebtedness of that Guarantor. The obligations of each Guarantor under
its Subsidiary Guarantee will be limited as necessary to prevent that Subsidiary
Guarantee from constituting a fraudulent conveyance under applicable law. See
"Risk Factors--Fraudulent Conveyance Matters."

     A Guarantor may not sell or otherwise dispose of all or substantially all
of its assets, or consolidate with or merge with or into, whether or not such
Guarantor is the surviving person, another person unless:

     o    immediately after giving effect to that transaction, no Default or
          Event of Default exists; and

     o    either:

          (1)  the person acquiring the property in any such sale or disposition
               or the person formed by or surviving any such consolidation or
               merger assumes all the obligations of that Guarantor pursuant to
               a supplemental indenture satisfactory to the trustee; or

          (2)  the Net Proceeds of such sale or other disposition are applied in
               accordance with the applicable provisions of the indenture.

     The Subsidiary Guarantee of a Guarantor will be released:

     o    in connection with any sale or other disposition of all or
          substantially all of the assets of that Guarantor, including by way of
          merger or consolidation, if Concentra Operating applies the Net
          Proceeds of that sale or other disposition in accordance with the
          applicable provisions of the indenture;

     o    in connection with the sale of all of the Capital Stock of a Guarantor
          if Concentra Operating applies the Net Proceeds of that sale in
          accordance with the applicable provisions of the indenture; or

     o    if Concentra Operating designates any Restricted Subsidiary that is a
          Guarantor as an Unrestricted Subsidiary.

     The Net Proceeds of an Asset Sale may be used by Concentra Operating to
make an offer to holders for the repurchase of notes. See "--Repurchase at the
Option of Holders--Asset Sales."


OPTIONAL REDEMPTION

     GENERAL. After August 15, 2004, Concentra Operating may redeem all or a
part of these notes, upon not less than 30 nor more than 60 days' notice, at the
redemption prices, expressed as percentages of principal amount, set forth below
plus accrued and unpaid interest on the new notes, to the applicable redemption
date, if redeemed during the twelve-month period beginning on August 15 of the
years indicated below:

     YEAR                                                    PERCENTAGE
     ----                                                    ----------
     2004 .................................................   106.500%
     2005 .................................................   104.875%
     2006 .................................................   103.250%
     2007 .................................................   101.625%
     2008 and thereafter ..................................   100.000%

     UPON EQUITY OFFERINGS. At any time prior to August 15, 2002, Concentra
Operating may on one or more occasions redeem up to 25% of the aggregate
principal amount of notes originally issued under the indenture at a redemption
price of 113% of the principal amount of the notes, plus accrued and unpaid
interest to the redemption date, with the net cash proceeds of one or more
Equity Offerings; provided that:

     o    at least 75% of the aggregate principal amount of notes remains
          outstanding immediately after the occurrence of such redemption,
          excluding notes held by Concentra Operating and its Subsidiaries; and


                                       86
<PAGE>


     o    the redemption must occur within 90 days of the date of the closing of
          such Equity Offering.

     Except pursuant to the preceding paragraphs, the notes will not be
redeemable at Concentra Operating's option prior to August 15, 2004.

     SELECTION AND NOTICE. If less than all of the notes are to be redeemed at
any time, the trustee will select notes for redemption as follows:

     o    if the notes are listed, in compliance with the requirements of the
          principal national securities exchange on which the notes are listed;
          or

     o    if the notes are not so listed, on a pro rata basis, by lot or by such
          method as the trustee shall deem fair and appropriate.

     No notes of $1,000 or less shall be redeemed in part. Notices of redemption
shall be mailed by first class mail at least 30 but not more than 60 days before
the redemption date to each holder of notes to be redeemed at its registered
address. Notices of redemption may not be conditional.

     If any note is to be redeemed in part only, the notice of redemption that
relates to that note shall state the portion of the principal amount of new
notes to be redeemed. A new note in principal amount equal to the unredeemed
portion of the original note will be issued in the name of the holder of new
notes upon cancellation of the original note. Notes called for redemption become
due on the date fixed for redemption. On and after the redemption date, interest
ceases to accrue on notes or portions of them called for redemption.


MANDATORY REDEMPTION

      Except as set forth under the caption "--Repurchase at the Option of
Holders," we is not required to make mandatory redemption or sinking fund
payments with respect to the notes.


REPURCHASE AT THE OPTION OF HOLDERS

      CHANGE OF CONTROL. If a Change of Control occurs, each holder of notes
will have the right to require Concentra Operating to repurchase all or any
part, equal to $1,000 or an integral multiple of $1,000, of that holder's notes
pursuant to the Change of Control Offer. In the Change of Control Offer,
Concentra Operating will offer a Change of Control Payment in cash equal to 101%
of the aggregate principal amount of notes repurchased plus any accrued and
unpaid interest on the notes to the date of purchase. Within 60 days following
any Change of Control, Concentra Operating will mail a notice to each holder
describing the transaction or transactions that constitute the Change of Control
and offering to repurchase notes on the Change of Control Payment Date, being no
later than five business days after the termination of the Change of Control
Offer, pursuant to the procedures required by the indenture and described in
such notice. Concentra Operating will comply with the requirements of the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the notes as a result of a Change of Control.

      On the Change of Control Payment Date, Concentra Operating will, to the
extent lawful:

     o    accept for payment all notes or portions of new notes properly
          tendered pursuant to the Change of Control Offer;

     o    deposit with the paying agent an amount equal to the Change of Control
          Payment in respect of all notes or portions of notes so tendered; and

     o    deliver or cause to be delivered to the trustee the notes so accepted
          together with an Officers' Certificate stating the aggregate principal
          amount of notes or portions of notes being purchased by Concentra
          Operating.


                                       87
<PAGE>


     The paying agent will promptly mail to each holder of notes so tendered the
Change of Control Payment for such notes, and the trustee will promptly
authenticate and mail, or cause to be transferred by book entry, to each holder
a new note equal in principal amount to any unpurchased portion of any notes
surrendered; provided that each such new note will be in a principal amount of
$1,000 or an integral multiple of $1,000.

     Prior to complying with any of the provisions of this "--Repurchase at the
Option of Holders--Change of Control" covenant, but in any event within 90 days
following a Change of Control, Concentra Operating will either repay all
outstanding Senior Indebtedness or obtain any requisite consents, under all
agreements governing outstanding Senior Indebtedness to permit the repurchase of
notes required by this covenant. Concentra Operating will publicly announce the
results of the Change of Control Offer on or as soon as practicable after the
Change of Control Payment Date.

     The provisions described above that require Concentra Operating to make a
Change of Control Offer following a Change of Control will be applicable
regardless of whether or not any other provisions of the indenture are
applicable. Except as described above with respect to a Change of Control, the
indenture does not contain provisions that permit the holders of the notes to
require that Concentra Operating repurchase or redeem the notes in the event of
a takeover, recapitalization or similar transaction.

     Concentra Operating's outstanding Senior Indebtedness currently prohibits
Concentra Operating from purchasing any notes, and also provides that certain
change of control events with respect to Concentra and/or Concentra Operating
would constitute a default under the agreements governing the Senior
Indebtedness. Any future credit agreements or other agreements relating to
Senior Indebtedness to which Concentra Operating becomes a party may contain
similar restrictions and provisions. In the event a Change of Control occurs at
a time when Concentra Operating is prohibited from purchasing notes, Concentra
Operating could seek the consent of its senior lenders to the purchase of notes
or could attempt to refinance the borrowings that contain such prohibition. If
Concentra Operating does not obtain such a consent or repay such borrowings,
Concentra Operating will remain prohibited from purchasing notes. In such case,
Concentra Operating's failure to purchase tendered notes would constitute an
Event of Default under the indenture which would, in turn, constitute a default
under such Senior Indebtedness. In such circumstances, the subordination
provisions in the indenture would likely restrict payments to the holders of
notes.

     Concentra Operating will not be required to make a Change of Control Offer
upon a Change of Control if a third party makes the Change of Control Offer in
the manner, at the times and otherwise in compliance with the requirements set
forth in the indenture applicable to a Change of Control Offer made by Concentra
Operating and purchases all notes validly tendered and not withdrawn under such
Change of Control Offer.

     The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the assets of Concentra Operating and its Subsidiaries taken as a whole.
Although there is a limited body of case law interpreting the phrase
"substantially all," there is no precise established definition of the phrase
under applicable law. Accordingly, the ability of a holder of notes to require
Concentra Operating to repurchase such notes as a result of a sale, lease,
transfer, conveyance or other disposition of less than all of the assets of
Concentra Operating and its Subsidiaries taken as a whole to another person or
group may be uncertain.

     ASSET SALES. Concentra Operating will not, and will not permit any of its
Restricted Subsidiaries to, complete an Asset Sale unless:

     (1)  Concentra Operating or the Restricted Subsidiary, as the case may be,
          receives consideration at the time of such Asset Sale at least equal
          to the fair market value of the assets or Equity Interests issued or
          sold or otherwise disposed of;

     (2)  such fair market value is determined by Concentra Operating's board of
          directors and evidenced by a resolution of the board of directors set
          forth in an officers' certificate delivered to the trustee PROVIDED
          that the board of directors' determination must be based on an opinion
          issued by an accounting, appraisal or investment banking firm of
          national standing if such fair market value exceeds $35 million; and


                                       88
<PAGE>


     (3)  at least 75% of the consideration received by Concentra Operating or
          such Restricted Subsidiary is in the form of cash or Cash Equivalents.
          For purposes of this provision, each of the following shall be deemed
          to be cash:

          o    any liabilities, as shown on Concentra Operating's or the
               Restricted Subsidiary's most recent balance sheet, of Concentra
               Operating or any Restricted Subsidiary, other than contingent
               liabilities and liabilities that are by their terms subordinated
               to the notes or any Subsidiary Guarantee, that are assumed by the
               transferee of any such assets pursuant to a customary novation
               agreement that releases Concentra Operating or such Restricted
               Subsidiary from further liability; and

          o    any securities, notes or other obligations received by Concentra
               Operating or any such Restricted Subsidiary from such transferee
               that are contemporaneously, subject to ordinary settlement
               periods, converted by Concentra Operating or such Restricted
               Subsidiary into cash or Cash Equivalents, to the extent of the
               cash received in that conversion.

     The 75% limitation referred to above will not apply to any Asset Sale in
which the cash or Cash Equivalents portion of the consideration received,
determined in accordance with the preceding sentence, is equal to or greater
than what the after-tax proceeds would have been had such Asset Sale complied
with the 75% limitation.

     Within 270 days after the receipt of any Net Proceeds from an Asset Sale,
Concentra Operating or any such Restricted Subsidiary may apply such Net
Proceeds, at its option:

     (1)  to repay or repurchase Senior Indebtedness of Concentra Operating or
          any Restricted Subsidiary;

     (2)  to acquire all or substantially all the assets of, or a majority of
          the Voting Stock of, another Permitted Business;

     (3)  to make a capital expenditure in a Permitted Business;

     (4)  to acquire other assets, other than securities, that are used or
          useful in a Permitted Business; or

     (5)  to make an Asset Sale Offer, treating the Net Proceeds as Excess
          Proceeds for all purposes.

     Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph will constitute excess proceeds. When the
aggregate amount of these excess proceeds exceeds $15 million, Concentra
Operating will be required to make an offer to all holders of notes to purchase
the maximum principal amount of notes that may be purchased out of the excess
proceeds. The offer price in any such offer will be equal to 100% of the
principal amount plus any accrued and unpaid interest to the date of purchase,
and will be payable in cash. Any excess proceeds which remain after consummation
of such an offer, may be used by Concentra Operating for general corporate
purposes. If the aggregate principal amount of notes tendered into such an offer
exceeds the amount of excess proceeds, the trustee shall select the notes to be
purchased on a pro rata basis. Upon completion of each such offer, the amount of
excess proceeds shall be reset at zero.


CERTAIN COVENANTS

     RESTRICTED PAYMENTS. Concentra Operating will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly, make any Restricted
Payment unless, at the time of and after giving effect to such Restricted
Payment:

     (1)  no Default or Event of Default shall have occurred and be continuing
          or would occur as a consequence of such Restricted Payment;


                                       89
<PAGE>


     (2)  Concentra Operating would not be permitted to incur at least $1.00 of
          additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
          test set forth in the first paragraph of the covenant described below
          under the caption "--Certain Covenants--Incurrence of Indebtedness and
          Issuance of Preferred Stock"; and

     (3)  such Restricted Payment, together with the aggregate amount of all
          other Restricted Payments made by Concentra Operating and its
          Restricted Subsidiaries after August 17, 1999, excluding Restricted
          Payments permitted by clauses (1) through (6), (12), (14) and (15) of
          the next succeeding paragraph, is less than the sum, without
          duplication, of:

          (a)  50% of the Consolidated Net Income of Concentra Operating for the
               period, taken as one accounting period, from the beginning of the
               first full fiscal quarter commencing after August 17, 1999 to the
               end of Concentra Operating's most recently ended fiscal quarter
               for which internal financial statements are available at the time
               of such Restricted Payment, or, if such Consolidated Net Income
               for such period is a deficit, less 100% of such deficit; plus

          (b)  100% of the aggregate net proceeds, including the fair-market
               value of property other than cash, received by Concentra
               Operating as a contribution to Concentra Operating's capital or

               Stock or convertible debt securities that have been converted
               into Disqualified Stock; plus

          (c)  to the extent that any Restricted Investment that was made after
               August 17, 1999 is sold for cash or otherwise liquidated or
               repaid for cash, the lesser of

               o    the cash return of capital with respect to such Restricted
                    Investment, less any cost of disposition, and

               o    the initial amount of such Restricted Investment; plus

          (d)  the amount by which Indebtedness of Concentra Operating or its
               Restricted Subsidiaries is reduced on Concentra Operating's
               balance sheet upon the conversion or exchange subsequent to
               August 17, 1999 of any Indebtedness of Concentra Operating
               convertible or exchangeable for Equity Interests, other than
               Disqualified Stock, of Concentra Operating, less the amount of
               any cash, or other property, distributed by Concentra Operating
               or any Restricted Subsidiary upon such conversion or exchange;
               plus

          (e)  if any Unrestricted Subsidiary pays any cash dividends or cash
               distributions to Concentra Operating or any of its Restricted
               Subsidiaries, 100% of any such cash dividends or cash
               distributions made after August 17, 1999.

thereby, the preceding provisions will not prohibit:

     (1)  the payment of any dividend within 60 days after the date of its

          issuance, other than to a subsidiary of Concentra Operating, of, other
          Equity Interests of Concentra Operating, other than Disqualified
          Stock; PROVIDED that the amount of any such net cash proceeds that are
          utilized for such redemption, repurchase, retirement, defeasance or
          other acquisition shall be excluded from clause (3)(b) of the
          preceding paragraph;

          amount of Restricted Payments;

     (10) if immediately before and immediately after giving them effect, no
          Default or Event of Default has occurred and Concentra Operating would
          have been permitted to incur at least $1.00 of additional Indebtedness
          pursuant to the Fixed Charge Coverage Ratio test set forth in the
          first paragraph of the covenant described below under the caption

          Preferred Stock", payments of cash dividends to Concentra in an amount
          sufficient to enable Concentra to make semi-annual payments after
          August 15, 2004 of cash interest not in excess of 14% per annum on the
          principal amount of Concentra Senior Discount Debentures, PROVIDED
          that Concentra is otherwise unable to pay such interest and such
          dividends are applied directly to the payment of such interest; and
          provided further, that the amount of any such payments will be
          included in subsequent calculations of the amount of Restricted

          subordinated notes in accordance with their respective terms in effect

          be included in subsequent calculations of the amount of Restricted
          Payments;

     (12) payments to Concentra in an amount equal to the amount of income tax
          that Concentra Operating and the Restricted Subsidiaries would have
          paid had they filed consolidated tax returns on a separate company
          basis in any given year, less the amount of such taxes paid or to be
          paid directly by Concentra Operating and the Restricted Subsidiaries
          for such years;

     (13) an amount not to exceed $1.0 million in any fiscal year to permit
          Concentra to pay:

          (a)  franchise taxes and other fees required to maintain its legal
               existence; and

          (b)  its corporate overhead expenses incurred in the ordinary course
               of business, its audit expenses, any filing fees required by the

               who perform services for both Concentra and Concentra Operating;

          subsequent calculations of the amount of Restricted Payments;

          will be included in subsequent calculations of the amount of

     The amount of all Restricted Payments, other than cash, shall be the fair
market value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by Concentra Operating or such Subsidiary,
as the case may be, pursuant to the Restricted Payment. The fair market value of
any non-cash Restricted Payment shall be determined in good faith by the board
of directors whose resolution shall be delivered to the trustee. The board of
directors' determination must be based upon an opinion or appraisal issued by an
accounting, appraisal or investment banking firm of national standing if such
fair market value exceeds $20 million. Not later than the date of making any
Restricted Payment, Concentra Operating shall deliver to the trustee an
officers' certificate stating that such Restricted Payment is permitted and
setting forth the basis upon which the calculations required by this "--
Restricted Payments" covenant were computed, together with a copy of any
fairness opinion or appraisal required by the indenture.

     INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK. Concentra
Operating will not, and will not permit any of its Subsidiaries to, directly or
indirectly, Incur any Indebtedness, including Acquired Debt, and Concentra
Operating will not issue any Disqualified Stock or preferred stock and will not
permit any of its Restricted Subsidiaries to issue any Disqualified Stock or
preferred stock.

     Despite the above, Concentra Operating may Incur Indebtedness, including
Acquired Debt, or issue Disqualified Stock or preferred stock and Concentra
Operating's Restricted Subsidiaries may Incur Indebtedness, including Acquired
Debt, and issue Disqualified Stock or preferred stock if the Fixed Charge
Coverage Ratio for Concentra Operating's most recently ended four full fiscal
quarters for which internal financial statements are available immediately
preceding the date on which such additional Indebtedness is Incurred or such
Disqualified Stock or preferred stock is issued:

     (1)  for such dates from August 17, 1999 up to but not including September
          30, 2000, would have been at least 2 to 1;


                                       92
<PAGE>


     (2)  for such dates from September 30, 2000 up to but not including March
          31, 2001, would have been at least 2.25 to 1; and

     (3)  after March 31, 2001 would have been at least 2.50 to 1;

each determined on a pro forma basis, on the assumption that the net proceeds
from the additional Indebtedness had been received, or the Disqualified Stock or
preferred stock had been issued, as the case may be, at the beginning of such
four-quarter period.

     The above will not prohibit the Incurrence of any of the following items of
Indebtedness:

     (l)  Indebtedness and letters of credit of Concentra Operating or any of
          its Restricted Subsidiaries pursuant to our senior credit facilities;
          PROVIDED that the aggregate amount of all Indebtedness of Concentra
          Operating and the Guarantors outstanding under our senior credit
          facilities after giving effect to such incurrence does not exceed an
          amount equal to $475 million at any one time;

     (2)  Existing Indebtedness of Concentra Operating and its Restricted
          Subsidiaries;

     (3)  Indebtedness of Concentra Operating and the Guarantors represented by
          the notes and the Subsidiary Guarantees;

     (4)  Indebtedness of Concentra Operating or any of its Restricted
          Subsidiaries represented by Capital Lease Obligations, mortgage
          financings or purchase money obligations, in each case incurred for
          the purpose of financing all or any part of the purchase price or cost
          of construction or improvement of property, plant or equipment used in
          the business of Concentra Operating or such Restricted Subsidiary,
          whether through the direct purchase of assets or the Capital Stock of
          any person owning such Assets, in an aggregate principal amount or
          accreted value, as applicable, not to exceed $15 million at any time
          outstanding;

     (5)  Permitted Refinancing Indebtedness of Concentra Operating or any of
          its Restricted Subsidiaries in exchange for, or the net proceeds of
          which are used to refund, refinance or replace Indebtedness, other
          than intercompany Indebtedness, that was permitted by the indenture to
          be incurred under the first paragraph of this covenant or clauses (3)
          or (14) of this paragraph;

     (6)  Indebtedness between Concentra Operating and any of its Restricted
          Subsidiaries or between any of its Restricted Subsidiaries; provided,
          however, that:

          (a)  if Concentra Operating or any Guarantor is the obligor on such
               Indebtedness, such Indebtedness must be expressly subordinated to
               the prior payment in full in cash of all Obligations with respect
               to the notes, in the case of Concentra Operating, or the
               Subsidiary Guarantee of such Guarantor, in the case of a
               Guarantor; and

          (b)  o    any subsequent issuance or transfer of Equity Interests that
                    results in any such Indebtedness being held by a person
                    other than Concentra Operating or a wholly-owned Restricted
                    Subsidiary and

               o    any sale or other transfer of any such Indebtedness to a
                    person that is not either Concentra Operating or a
                    wholly-owned Restricted Subsidiary

               shall be deemed, in each case, to constitute an Incurrence of
               such Indebtedness by Concentra Operating or such Restricted
               Subsidiary, as the case may be, that was not permitted by this
               clause (6);

     (7)  Hedging Obligations of Concentra Operating or any of its Restricted
          Subsidiaries that are for the purpose of hedging interest rate risk
          with respect to any Indebtedness that is permitted by the terms of the
          indenture to be outstanding;


                                       93
<PAGE>


     (8)  the Guarantee by Concentra Operating or any of its Restricted
          Subsidiaries of Indebtedness of Concentra Operating or a Restricted
          Subsidiary of Concentra Operating that was permitted by another
          provision of this covenant;

     (9)  Non-Recourse Debt of Concentra Operating's Unrestricted Subsidiaries;
          provided, however, that if any such Indebtedness ceases to be
          Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be
          deemed to constitute an Incurrence of Indebtedness by a Restricted
          Subsidiary of Concentra Operating that was not permitted by this
          clause (9);

     (10) Indebtedness of Concentra Operating or any of its Restricted
          Subsidiaries constituting reimbursement obligations with respect to
          letters of credit issued in the ordinary course of business, including
          without limitation to letters of credit in respect of workers'
          compensation claims or self-insurance, or other Indebtedness with
          respect to reimbursement type obligations regarding workers'
          compensation claims; PROVIDED, HOWEVER, that upon the drawing of such
          letters of credit or the incurrence of such Indebtedness, such
          obligations are reimbursed within 30 days following such drawing or
          incurrence;

     (11) Indebtedness arising from agreements of Concentra Operating or a
          Restricted Subsidiary providing for indemnification, adjustment of
          purchase price or similar obligations, in each case, incurred or
          assumed in connection with the disposition of any business, asset or
          Subsidiary, other than guarantees of Indebtedness incurred by any
          person acquiring all or any portion of such business, assets or
          Subsidiary for the purpose of financing such acquisition; PROVIDED
          that:

          (a)  such Indebtedness is not reflected on the balance sheet of
               Concentra Operating or any Restricted Subsidiary, contingent
               obligations referred to in a footnote or footnotes to financial
               statements and not otherwise reflected on the balance sheet will
               not be deemed to be reflected on such balance sheet for purposes
               of this clause (a); and

          (b)  the maximum aggregate liability in respect of such Indebtedness
               shall at no time exceed the gross proceeds, including non-cash
               proceeds (the fair market value of such non-cash proceeds being
               measured at the time received and without giving effect to any
               such subsequent changes in value) actually received by Concentra
               Operating and/or such Restricted Subsidiary in connection with
               such disposition;

     (12) obligations in respect of performance, surety and similar bonds and
          completion guarantees PROVIDED by Concentra Operating or any
          Restricted Subsidiary in the ordinary course of business;

     (13) Indebtedness arising from the honoring by a bank or other financial
          institution of a check, draft or similar instrument, except in the
          case of daylight overdrafts, drawn against insufficient funding in the
          ordinary course of business, PROVIDED, HOWEVER, that such Indebtedness
          is extinguished within five business days of incurrence; and

     (14) additional Indebtedness of Concentra Operating or any of its
          Restricted Subsidiaries, including Attributable Debt incurred after
          August 17, 1999, in an aggregate principal amount, or accreted value,
          as applicable, at any time outstanding, including all Permitted
          Refinancing Indebtedness incurred to refund, refinance or replace any
          other Indebtedness incurred pursuant to this clause (14), not to
          exceed $25 million.

     For purposes of determining compliance with this "--Certain
Covenants-Incurrence of Indebtedness and Issuance of Preferred Stock" covenant,
in the event that an item of proposed Indebtedness meets the criteria of more
than one of the categories of permitted debt described in clauses (1) through
(14) above or pursuant to the first paragraph of this covenant, Concentra
Operating will be permitted to classify such item of Indebtedness in any manner
that complies with this covenant. In addition, Concentra Operating may, at any
time, change the classification of an item of Indebtedness, or any portion of
Indebtedness, to any other clause or to the first paragraph of this covenant
PROVIDED that Concentra Operating would be permitted to Incur such item of
Indebtedness, or the portion of Indebtedness, pursuant to such other clause or
the first paragraph of this covenant, as the case may be, at such time


                                       94
<PAGE>


of reclassification. Accrual of interest, accretion or amortization of original
issue discount and the accretion of accreted value will not be deemed to be an
Incurrence of Indebtedness for purposes of this covenant.

     LIENS. Concentra Operating will not, and will not permit any of its
Restricted Subsidiaries to Incur or become effective any Lien of any kind
securing trade payables, Attributable Debt or Indebtedness that does not
constitute Senior Indebtedness, other than Permitted Liens, upon any of their
property or assets, now owned or hereafter acquired unless:

     o    in the case of Liens securing Indebtedness that is expressly
          subordinated or junior in right of payment to the notes, the notes are
          secured on a senior basis to the obligations so secured until such
          time as such obligations are no longer secured by a Lien; and

     o    in all other cases, the notes are secured on an equal and ratable
          basis with the obligations so secured until such time as such
          obligations are no longer secured by a Lien.

     DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED SUBSIDIARIES.
Concentra Operating will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any consensual encumbrance or consensual restriction on the ability of
any Restricted Subsidiary to:

     o    pay dividends or make any other distributions to Concentra Operating
          or any of its Restricted Subsidiaries (a) on its Capital Stock or (b)
          with respect to any other interest or participation in, or measured
          by, its profits;

     o    pay any Indebtedness owed to Concentra Operating or any of Concentra
          Operating's Restricted Subsidiaries;

     o    make loans or advances to Concentra Operating or any of Concentra
          Operating's Restricted Subsidiaries; or

     o    transfer any of its properties or assets to Concentra Operating or any
          of Concentra Operating's Restricted Subsidiaries.

     However, the preceding restrictions will not apply to encumbrances or
restrictions existing under or by reason of:

     o    any encumbrance or restriction pursuant to an agreement in effect at
          or entered into on August 17, 1999, including:

          (1)  our senior credit facilities as in effect as of August 17, 1999,
               and any amendments, modifications, restatements, renewals,
               increases, supplements, refundings, replacements or refinancings
               of those credit facilities, PROVIDED that such amendments,
               modifications, restatements, renewals, increases, supplements,
               refundings, replacements or refinancings are no more restrictive,
               taken as a whole, as determined in the good faith judgment of
               Concentra Operating's board of directors, with respect to such
               dividend and other payment restrictions than those contained in
               our senior credit facilities as in effect on August 17, 1999; and

          (2)  the indenture and the notes;

     o    any applicable law, rule, regulation or order;

     o    any instrument governing Indebtedness or Capital Stock of a person
          acquired by Concentra Operating or any of its Restricted Subsidiaries
          as in effect at the time of such acquisition, (except to the extent
          incurred in connection with or in contemplation of such acquisition,
          which encumbrance or restriction is not applicable to any person, or
          the properties or assets of any person, other than the person, or the
          property or


                                       95
<PAGE>


          assets of the person, so acquired, PROVIDED THAT, in the case of
          Indebtedness, such Indebtedness was permitted by the terms of the
          indenture to be incurred;

     o    customary non-assignment provisions in leases entered into in the
          ordinary course of business and consistent with past practices;

     o    any Purchase Money Note or other Indebtedness or contractual
          requirements incurred with respect to a Qualified Receiveables
          Transaction relating exclusively to a Receiveables Entity that, in the
          good faith determination of the board of directors of Concentra
          Operating, are necessary to effect such Qualified Receiveables
          Transaction;

     o    purchase money obligations for property acquired in the ordinary
          course of business that impose restrictions on the property so
          acquired of the nature described in the last clause of the preceding
          paragraph;

     o    restrictions with respect solely to a Restricted Subsidiary of
          Concentra Operating imposed pursuant to a binding agreement which has
          been entered into for the sale or disposition of all or substantially
          all of the Capital Stock or assets of such Restricted Subsidiary,

          assets being sold of such Restricted Subsidiary;

     o    provisions with respect to the disposition or distribution of assets

     o    Permitted Refinancing Indebtedness, PROVIDED that the material
          restrictions contained in the agreements governing such Permitted
          Refinancing Indebtedness are no more restrictive, in the good faith
          judgment of Concentra Operating's board of directors, taken as a
          whole, to the holders of notes than those contained in the agreements
          governing the Indebtedness being refinanced; and

     o    restrictions on cash or other deposits or net worth imposed by
          customers under contracts entered into in the ordinary course of
          business.

     MERGER, CONSOLIDATION OR SALE OF ASSETS. Concentra Operating may not:

     o    consolidate or merge with or into another person, whether or not
          Concentra Operating is the surviving corporation; or

     o    sell, assign, transfer, convey or otherwise dispose of all or
          substantially all of its properties or assets, in one or more related
          transactions, to another person unless:

          (1)  either:

               (a)  Concentra Operating is the surviving corporation; or

               (b)  the person formed by or surviving any such consolidation or
                    merger, if other than Concentra Operating, or to which such
                    sale, assignment, transfer, conveyance or other disposition
                    shall have been made is a corporation organized or existing
                    under the laws of the United States, any state of the United
                    States or the District of Columbia;

          (2)  the person formed by or surviving any such consolidation or
               merger, if other than Concentra Operating, or the person to which
               such sale, assignment, transfer, conveyance or other disposition
               shall have been made expressly assumes all the obligations of
               Concentra Operating under the notes and the indenture pursuant to
               a supplemental indenture in a form reasonably satisfactory to the
               trustee;

          (3)  immediately after giving pro forma effect to such transaction no
               Default or Event of Default exists; and


                                       96
<PAGE>


          (4)  Concentra Operating or person formed by or surviving any such
               consolidation or merger, if other than Concentra Operating, or to
               which such sale, assignment, transfer, conveyance or other
               disposition shall have been made;

               (a)  will, after giving pro forma effect to such merger, on the
                    assumption that it had occurred at the beginning of the
                    applicable four-quarter period, be permitted to incur at
                    least $1.00 of additional Indebtedness pursuant to the Fixed
                    Charge Coverage Ratio test set forth in the first paragraph
                    of the covenant described above under the caption "--
                    Certain Covenants --Incurrence of Indebtedness and Issuance
                    of Preferred Stock"; or

               (b)  would, together with its Restricted Subsidiaries, have a
                    higher Fixed Charge Coverage Ratio immediately after such
                    merger, after giving pro forma effect to such merger, on the
                    assumption that it had occurred at the beginning of the
                    applicable four-quarter period, than the Fixed Charge
                    Coverage Ratio of Concentra Operating and its Subsidiaries
                    immediately prior to the transaction.

     The preceding clause (4) will not prohibit:

               (a)  a merger between Concentra Operating and a wholly-owned
                    Subsidiary; or

               (b)  a merger between Concentra Operating and an Affiliate
                    incorporated solely for the purpose of reincorporating
                    Concentra Operating in another state of the United States;

so long as, in each case, the amount of Indebtedness of Concentra Operating and
its Restricted Subsidiaries is not increased thereby.

     In addition, Concentra Operating may not, directly or indirectly, lease all
or substantially all of its properties or assets, in one or more related
transactions, to any other person. This covenant will not be applicable to a
sale, assignment, transfer, conveyance or other disposition of assets between or
among Concentra Operating and any of its wholly-owned Restricted Subsidiaries.

     TRANSACTIONS WITH AFFILIATES. Concentra Operating will not, and will not
permit any of its Restricted Subsidiaries to engage in an Affiliate Transaction
unless:

     (1)  such Affiliate Transaction is on terms that are no less favorable to
          Concentra Operating or the relevant Restricted Subsidiary than those
          that would have been obtained in a comparable transaction by Concentra
          Operating or such Restricted Subsidiary made on an arm's-length basis
          with an unrelated person; and

     (2)  Concentra Operating delivers to the trustee:

          (a)  with respect to any Affiliate Transaction or series of related
               Affiliate Transactions involving aggregate consideration in
               excess of $5 million, a resolution of the board of directors set
               forth in an officers' certificate certifying that such Affiliate
               Transaction complies with clause (1) above and that such
               Affiliate Transaction has been approved by a majority of the
               disinterested members of the board of directors; and

          (b)  with respect to any Affiliate Transaction or series of related
               Affiliate Transactions involving aggregate consideration in
               excess of $15 million, an opinion as to the fairness to the
               holders of such Affiliate Transaction from a financial point of
               view issued by an accounting, appraisal or investment banking
               firm of national standing.

     The following items shall not be deemed to be Affiliate Transactions and,
therefore, will not be subject to the provisions of the prior paragraph:

     (1)  customary directors' fees to persons who are not otherwise Affiliates
          of Concentra Operating;


                                       97
<PAGE>


     (2)  transactions between or among Concentra Operating and/or its
          Restricted Subsidiaries;

     (3)  the payment of Affiliate Management Fees in an amount in any calendar
          year not to exceed the greater of:

          (a)  $1 million; and

          (b)  1% of Consolidated EBITDA;

     (4)  payments by Concentra Operating or any of its Restricted Subsidiaries
          to Welsh Carson, Ferrer Freeman and their respective Affiliates made
          for any:

          (a)  financial advisory, financing, underwriting or placement
               services; or

          (b)  in respect of other investment banking activities, including,
               without limitation, in connection with acquisitions or
               divestitures;

          which payments are approved in good faith by a majority of the board
          of directors of Concentra Operating or a committee of the board of
          directors consisting of disinterested members;

     (5)  loans or advances to employees in accordance with past practice made
          in the ordinary course of business which are approved in good faith by
          a majority of the board of directors of Concentra Operating or a
          committee of the board of directors consisting of disinterested
          members;

     (6)  any agreement as in effect on August 17, 1999 or any amendment to such
          agreement, so long as any such amendment is no less favorable to
          Concentra Operating and its Restricted Subsidiaries;

     (7)  the existence of, or the performance by Concentra Operating or any of
          its Restricted Subsidiaries of its obligations under the terms of, our
          agreement and plan of merger, registration rights agreement or
          purchase agreement related to our merger with Yankee, to which it is a
          party on or after August 17, 1999; PROVIDED, HOWEVER, that the
          existence of, or the performance by Concentra Operating or any of its
          Restricted Subsidiaries of obligations under any future amendment to
          any such existing agreement or under any similar agreement entered
          into after August 17, 1999 shall only be permitted by this clause;

     (8)  the payment of all fees and expenses related to our merger with Yankee
          and related transactions, including fees to Welsh Carson and Ferrer
          Freeman;

     (9)  any payment pursuant to any tax sharing agreement between Concentra
          Operating and Concentra or any other person with which Concentra
          Operating is required or permitted to file a consolidated tax return
          or with which Concentra Operating is or could be part of a
          consolidated, combined or unitary group for tax purposes; PROVIDED
          that in no event shall the amount permitted to be paid pursuant to all
          such agreements exceed the tax liabilities attributable solely to
          Concentra Operating and its Restricted Subsidiaries (whether as a
          consolidated, combined or unitary group);

     (10) Restricted Payments that are permitted by the provisions of the
          indenture described above under the caption "--Certain
          Covenants--Restricted Payments";

     (11) customary fees and compensation paid to, and indemnity provided on
          behalf of, officers, directors, employees or consultants of Concentra
          Operating or any of its Restricted Subsidiaries; and

     (12) any transaction involving ordinary course investment banking, merchant
          banking, commercial banking or related activities.

     Despite the above, the holders of notes will be entitled to receive payment
in full in cash of all amounts due or to become due in respect of the notes
before any payment is made with respect to Affiliate Management Fees in the


                                       98
<PAGE>


event of any distribution to creditors of Concentra Operating in any Insolvency
or Liquidation Proceeding with respect to Concentra Operating. No payments of
Affiliate Management Fees shall be made by Concentra Operating or any of its
Restricted Subsidiaries if the Fixed Charge Coverage Ratio for Concentra
Operating's most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date on which
Affiliate Management Fees are to be paid is less than 1.75 to 1; provided,
however, that such payments due but not paid shall accrue and shall be paid only
after such time as the Fixed Charge Coverage Ratio for a four full fiscal
quarter period is no longer less than or equal to 1.75 to 1.

     DESIGNATION OF RESTRICTED AND UNRESTRICTED SUBSIDIARIES. The board of
directors may designate any Restricted Subsidiary to be an Unrestricted
Subsidiary if that designation would not cause a Default. If a Restricted
Subsidiary is designated as an Unrestricted Subsidiary, all outstanding
Investments owned by Concentra Operating and its Restricted Subsidiaries, except
to the extent repaid in cash, in the Subsidiary so designated will be deemed to
be Restricted Payments at the time of such designation, to the extent not
designated a Permitted Investment, and will reduce the amount available for
Restricted Payments under the first paragraph of the covenant described above
under the caption "--Certain Covenants--Restricted Payments." All such
outstanding Investments will be valued at their fair market value at the time of
such designation, as determined in good faith by the board of directors. That
designation will only be permitted if such Restricted Payment would be permitted
at that time and if such Restricted Subsidiary otherwise meets the definition of
an Unrestricted Subsidiary. The board of directors may redesignate any
Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would
not cause a Default.

     ANTI-LAYERING. Concentra Operating will not, and will not permit any of its
Restricted Subsidiaries to, Incur any Indebtedness that is both:

     (1)  subordinate or junior in right of payment to any Senior Indebtedness;
          and

     (2)  senior in any respect in right of payment to the notes.

     No Guarantor will Incur any Indebtedness that is both:

     (1)  subordinate or junior in right of payment to any Senior Indebtedness
          of such Guarantor; and

     (2)  senior in any respect in right of payment to the Subsidiary
          Guarantees.

     SALE AND LEASEBACK TRANSACTIONS. Concentra Operating will not, and will not
permit any of its Restricted Subsidiaries to, enter into any sale and leaseback
transaction unless:

     (1)  Concentra Operating or such Restricted Subsidiary could have:

          (a)  incurred Indebtedness in an amount equal to the Attributable Debt
               relating to such sale and leaseback transaction under the Fixed
               Charge Coverage Ratio test in the first paragraph of the covenant
               described above under the caption "--Certain
               Covenants--Incurrence of Indebtedness and Issuance of Preferred
               Stock;" and

          (b)  incurred a Lien to secure such Indebtedness pursuant to the
               covenant described above under the caption "--Certain
               Covenants--Liens;"

     (2)  the gross cash proceeds of that sale and leaseback transaction are at
          least equal to the fair market value, as determined in good faith by
          the board of directors and set forth in an officers' certificate
          delivered to the trustee, of the property that is the subject of such
          sale and leaseback transaction; and

     (3)  the transfer of assets in such sale and leaseback transaction is
          permitted by, and Concentra Operating applies the proceeds of such
          transaction in compliance with, the covenant described above under the
          caption "-- Repurchase at the Option of Holders--Asset Sales."


                                       99
<PAGE>


     LIMITATION ON ISSUANCES AND SALES OF EQUITY INTERESTS IN RESTRICTED
SUBSIDIARIES. Concentra Operating will not, and will not permit any of its
Restricted Subsidiaries to, transfer, convey, sell, lease or otherwise dispose
of any Equity Interests in any Restricted Subsidiary or to issue any of its
Equity Interests, other than, if necessary, Equity Interests constituting
directors' qualifying shares, to any person except:

     (1)  to Concentra Operating or a wholly-owned Subsidiary, other than a
          Receivables Entity; or

     (2)  in compliance with the covenant described above under the caption
          "--Repurchase at the Option of Holders--Asset Sales" and immediately
          after giving effect to such issuance or sale, such Restricted
          Subsidiary would continue to be a Restricted Subsidiary.

     Despite the above, Concentra Operating may sell all the Equity Interests of
a Restricted Subsidiary as long as Concentra Operating complies with the terms
of the covenant described under the caption "--Repurchase at the Option of
Holders--Asset Sales."

     LIMITATIONS ON ISSUANCES OF GUARANTEES OF INDEBTEDNESS. Concentra Operating
will not permit any Restricted Subsidiary, directly or indirectly, to Incur
Indebtedness or Guarantee or pledge any assets to secure the payment of any
Indebtedness of Concentra Operating or any Restricted Subsidiary unless either
such Restricted Subsidiary:

     (1)  is a Guarantor; or

     (2)  simultaneously executes and delivers a supplemental indenture to the
          indenture and becomes a Guarantor, which Guarantee shall:

          (a)  with respect to any Guarantee of Senior Indebtedness, be
               subordinated in right of payment on the same terms as the notes
               are subordinated to such Senior Indebtedness; and

          (b)  with respect to any Guarantee of any other Indebtedness, be
               senior to or pari passu with such Restricted Subsidiary's other
               Indebtedness or Guarantee of or pledge to secure such other
               Indebtedness.

     Despite the above, any Subsidiary Guarantee of the notes shall provide by
its terms that it shall be automatically and unconditionally released and
discharged under the circumstances described above under the caption
"--Subsidiary Guarantees." The form of the Guarantee will be attached as an
exhibit to the indenture.

     ADDITIONAL GUARANTEES. If Concentra Operating shall acquire or create a
Restricted Subsidiary after August 17, 1999, or if any Subsidiary of Concentra
Operating becomes a Restricted Subsidiary, then such newly acquired or created
Restricted Subsidiary, other than a Permitted Joint Venture, shall become a
Guarantor and execute a supplemental indenture and deliver an opinion of
counsel, in accordance with the terms of the indenture.

     BUSINESS ACTIVITIES. Concentra Operating will not, and will not permit any
Restricted Subsidiary to, engage in any business other than a Permitted
Business.

     ADVANCES TO SUBSIDIARIES. All advances to Restricted Subsidiaries made by
Concentra Operating after August 17, 1999 will be evidenced by intercompany
notes in favor of Concentra Operating. Each intercompany note will be payable
upon demand and will bear interest at the same rate as the notes. A form of
intercompany note will be attached as an exhibit to the indenture.

     PAYMENTS FOR CONSENTS. Concentra Operating will not, and will not permit
any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any holder of notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of the indenture or the notes unless such consideration is offered to be paid
and is paid to all holders of the notes that consent, waive or agree to amend in
the time frame set forth in the solicitation documents relating to such consent,
waiver or agreement.

      REPORTS. Whether or not required by the Commission, so long as any notes
are outstanding, Concentra Operating will furnish or make available to the
holders of notes, within the time periods specified in the Commission's rules
and regulations:

     (l)  all quarterly and annual financial information that would be required
          to be contained in a filing with the Commission on Forms 10-Q and 10-K
          if Concentra Operating were required to file such Forms, including a
          "Management's Discussion and Analysis of Financial Condition and
          Results of Operations" and, with respect to the annual information
          only, a report on the annual financial statements by Concentra
          Operating's certified independent accountants; and

     (2)  all current reports that would be required to be filed with the
          Commission on Form 8-K if Concentra Operating were required to file
          such reports.

     If Concentra Operating has designated any of its Subsidiaries as
Unrestricted Subsidiaries, then the quarterly and annual financial information
required by the preceding paragraph shall include a reasonably detailed
presentation, either on the face of the financial statements or in the
accompanying footnotes, and in the "Management's Discussion and Analysis of
Financial Condition and Results of Operations" section, of the financial
condition and results of operations of Concentra Operating and its Restricted
Subsidiaries separate from the financial condition and results of operations of
the Unrestricted Subsidiaries of Concentra Operating.

     In addition, following this exchange offer, whether or not required by the
Commission, Concentra Operating will file a copy of all the information and
reports referred to in clauses (1) and (2) above with the Commission for public
availability within the time periods specified in the Commission's rules and
regulations (unless the Commission will not accept such a filing) and make such
information available to securities analysts and prospective investors upon
request. In addition, Concentra Operating has agreed that, for so long as any
notes remain outstanding, it will furnish to the holders and to securities
analysts and prospective investors, upon their request, the information required
to be delivered pursuant to Rule 144A(d) (4) under the Securities Act.


EVENTS OF DEFAULT AND REMEDIES

     Each of the following is an Event of Default under the indenture:

     (1)  default for 30 days in the payment when due of interest on the notes
          whether or not prohibited by the subordination provisions of the
          indenture;

     (2)  default in payment when due of the principal of or any premium on the
          notes, whether or not prohibited by the subordination provisions of
          the indenture;

     (3)  failure by Concentra Operating to comply with the provisions described
          under the captions "--Repurchase at the Option of Holders-Change of
          Control", "--Repurchase at the Option of Holders--Asset Sales",
          "--Certain Covenants-Restricted Payments", "--Certain
          Covenants--Incurrence of Indebtedness and Issuance of Preferred Stock"
          or "--Certain Covenants--Merger, Consolidation or Sale of Assets";

     (4)  failure by Concentra Operating for 60 days after notice from the
          trustee or holders of at least 25% in principal amount of the notes
          then outstanding to comply with any of its other agreements in the
          indenture or the notes;

     (5)  default under any mortgage, indenture or instrument under which there
          may be issued or by which there may be secured or evidenced any
          Indebtedness for borrowed money or Guarantee by Concentra Operating or
          any of its Restricted Subsidiaries, or the payment of which is
          guaranteed by Concentra Operating or any of its Restricted
          Subsidiaries, whether such Indebtedness or Guarantee now exists, or is
          created after August 17, 1999, if that default:


                                      101
<PAGE>


          (a)  is caused by a failure to pay principal of or any premium on such
               Indebtedness prior to the expiration of the grace period provided
               in such Indebtedness on the date of such default; or

          (b)  results in the acceleration of such Indebtedness prior to its
               express maturity;

          and, in each case, the principal amount of any such Indebtedness,
          together with the principal amount of any other such Indebtedness
          under which there has been a payment default or the maturity of which
          has been so accelerated, aggregates $20 million or more;

     (6)  failure by Concentra Operating or any of its Restricted Subsidiaries
          to pay final judgments aggregating in excess of $20 million, which
          judgments are not paid, discharged or stayed for a period of 60 days;

     (7)  except as permitted by the indenture, any Subsidiary Guarantee which
          shall be held in any judicial proceeding to be unenforceable or
          invalid or shall cease for any reason to be in full force and effect
          or any Guarantor, or any person acting on behalf of any Guarantor, who
          shall deny or disaffirm its obligations under its Subsidiary
          Guarantee; and

     (8)  certain events of bankruptcy or insolvency with respect to Concentra
          Operating or any of its Restricted Subsidiaries.

     In the event of a declaration of acceleration of the notes because an Event
of Default has occurred and is continuing as a result of the acceleration of any
Indebtedness described in clause (5) of the preceding paragraph, the declaration
of acceleration of the notes shall be automatically annulled if the holders of
any Indebtedness described in clause (5) of the preceding paragraph have
rescinded the declaration of acceleration in respect of such Indebtedness within
30 days of the date of such declaration and if:

     o    the annulment of the acceleration of notes would not conflict with any
          judgment or decree of a court of competent jurisdiction; and

     o    all existing Events of Default, except nonpayment of principal or
          interest on the notes that became due solely because of the
          acceleration of the notes, have been cured or waived.

     If any Event of Default occurs and is continuing, the trustee or the
holders of at least 25% in principal amount of the outstanding notes may declare
the principal of the notes to be due and payable immediately; provided, that so
long as any Indebtedness permitted to be incurred pursuant to our senior credit
facilities shall be outstanding, such acceleration shall not be effective until
the earlier of:

     o    an acceleration of any such Indebtedness under our senior credit
          facilities; or

     o    five business days after receipt by Concentra Operating and the agent
          bank to our senior credit facilities of written notice of such
          acceleration.

     If payment of the notes is accelerated because of an Event of Default,
Concentra Operating shall promptly notify the holders of the Senior Indebtedness
of the acceleration.

     Despite the above, in the case of an Event of Default arising from certain
events of bankruptcy or insolvency, with respect to Concentra Operating or any
of its Subsidiaries, the principal and any accrued but unpaid interest on all
outstanding notes shall become due and payable immediately without further
action or notice.

     Holders of the notes may not enforce the indenture or the notes except as
provided in the indenture. Subject to certain limitations, holders of a majority
in principal amount of the then outstanding notes may direct the trustee in its
exercise of any trust or power. The trustee may withhold from holders of the
notes notice of any continuing Default or Event of Default, except a Default or
Event of Default relating to the payment of principal or interest, if it
determines that withholding notice is in their interest.


                                      102
<PAGE>


     In the case of any Event of Default occurring on or after August 15, 2004,
by reason of any willful action or inaction taken or not taken by or on behalf
of Concentra Operating with the intention of avoiding payment of the premium
that Concentra Operating would have had to pay if Concentra Operating then had
elected to redeem the notes pursuant to the optional redemption provisions of
the indenture, an equivalent premium shall also become and be immediately due
and payable to the extent permitted by law upon the acceleration of the notes.
If an Event of Default occurs prior to August 15, 2004 by reason of any willful
action, or inaction, taken, or not taken, by or on behalf of Concentra Operating
with the intention of avoiding the prohibition on redemption of the notes prior
to August 15, 2004, then the premium specified in the indenture shall also
become immediately due and payable to the extent permitted by law upon the
acceleration of the notes.

     The holders of a majority in aggregate principal amount of the notes then
outstanding by notice to the trustee may on behalf of the holders of all of the
notes waive any existing Default or Event of Default and its consequences under
the indenture except a continuing Default or Event of Default in the payment of
interest or any premium on, or the principal of, the notes.

     Concentra Operating is required to deliver to the trustee annually a
statement regarding compliance with the indenture. Upon becoming aware of any
Default or Event of Default, Concentra Operating is required to deliver to the
trustee a statement specifying such Default or Event of Default.


NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

     No director, officer, employee, incorporator or stockholder of Concentra
Operating, or any Guarantor, as such, shall have any liability for any
obligations of Concentra Operating or the Guarantors under the notes, the
indenture, the Subsidiary Guarantees or for any claim based on, in respect of,
or by reason of, such obligations or their creation. Each holder of notes by
accepting a note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the notes. The waiver may not be
effective to waive liabilities under the federal securities laws.


LEGAL DEFEASANCE AND COVENANT DEFEASANCE

     Concentra Operating may, at its option, elect to completely defease the
notes. Such defeasance means that all of its obligations with respect to the
outstanding notes and all of the obligations of the Guarantors with respect to
their Subsidiary Guarantees would be discharged, except for:

     o    the rights of holders of outstanding notes to receive payments in
          respect of the principal of, any premium and interest on such notes
          when such payments are due from the trust referred to below;

     o    Concentra Operating's obligations with respect to the notes concerning
          issuing temporary notes, registration of notes, mutilated, destroyed,
          lost or stolen notes and the maintenance of an office or agency for
          payment and money for security payments held in trust;

     o    the rights, powers, trusts, duties and immunities of the trustee, and
          Concentra Operating's obligations in connection with the indenture;
          and

     o    the legal defeasance provisions of the indenture.

     In addition, Concentra Operating may, at its option, elect to defease a
covenant under the indenture and after that defeasance any omission to comply
with its obligations and the obligations of the Guarantors with respect to such
covenant will not constitute a Default or Event of Default. In the event a
covenant is defeased, certain events, not including non-payment, bankruptcy,
receivership, rehabilitation and insolvency events, described under the caption
"--Events of Default and Remedies" will no longer constitute an Event of Default
with respect to the notes.


                                      103
<PAGE>


     In order to exercise a defeasance:

     o    Concentra Operating must irrevocably deposit with the trustee, in
          trust, for the benefit of the holders of the notes, cash in U.S.
          dollars, non-callable Government Securities, or a combination of the
          two, in such amounts as will be sufficient, in the opinion of a
          nationally recognized firm of independent public accountants, to pay
          the principal of, any premium and interest on the outstanding notes on
          the stated maturity or on the applicable redemption date, as the case
          may be, and Concentra Operating must specify whether the notes are
          being defeased to maturity or to a particular redemption date;

     o    in the case of any defeasance, Concentra Operating shall have
          delivered to the trustee an opinion of counsel in the United States
          reasonably acceptable to the trustee confirming that the holders of
          the outstanding notes will not recognize income, gain or loss for
          federal income tax purposes as a result of such defeasance and will be
          subject to federal income tax on the same amounts, in the same manner
          and at the same times as would have been the case if such defeasance
          had not occurred;

     o    no Default or Event of Default shall have occurred and be continuing
          on the date of such deposit, other than a Default or Event of Default
          resulting from the borrowing of funds to be applied to such deposit;

     o    such defeasance will not result in a breach or violation of, or
          constitute a default under, any material agreement or instrument,
          other than the indenture, to which Concentra Operating or any of its
          Subsidiaries is a party or by which Concentra Operating or any of its
          Subsidiaries is bound;

     o    Concentra Operating must deliver to the trustee an officers'
          certificate stating that the deposit was not made by Concentra
          Operating with the intent of preferring the holders of notes over the
          other creditors of Concentra Operating with the intent of defeating,
          hindering, delaying or defrauding creditors of Concentra Operating or
          others;

     o    no event which is, or after notice or lapse of time or both would
          become, an Event of Default with respect to such notes or any other
          notes shall have occurred and be continuing at the time of such
          deposit or, with regard to any such event specified in paragraphs (7)
          and (8) under the above caption "--Events of Default and Remedies", at
          any time on or prior to the 90th day after the date of such deposit,
          it being understood that this condition shall not be deemed satisfied
          until after such 90th day; and

     o    Concentra Operating must deliver to the trustee an officers'
          certificate and an opinion of counsel, which opinion may be subject to
          customary assumptions and exclusions, each stating that all conditions
          precedent relating to the defeasance have been complied with.


AMENDMENT, SUPPLEMENT AND WAIVER

     With the consent of the holders of not less than a majority in principal
amount of the notes at the time outstanding, Concentra Operating and trustee are
permitted to amend or supplement the indenture or any supplemental indenture or
modify the rights of the holders; provided that without the consent of each
holder affected, no amendment, supplement, modification or waiver may:

     o    reduce the principal amount of notes whose holders must consent to an
          amendment, supplement or waiver;

     o    reduce the principal of or change the fixed maturity of any note or
          alter the provisions with respect to the redemption of the notes,
          other than provisions relating to the covenants described above under
          the caption "--Repurchase at the Option of Holders";

     o    reduce the rate of or change the time for payment of interest on any
          note;


                                      104
<PAGE>


     o    waive a Default or Event of Default in the payment of principal of or
          any premium or interest on the notes, except a rescission of
          acceleration of the notes by the holders of at least a majority in
          aggregate principal amount of the notes and a waiver of the payment
          default that resulted from such acceleration;

     o    make any note payable in money other than that stated in the notes;

     o    make any change in the provisions of the indenture relating to waivers
          of past Defaults or the rights of holders of notes to receive payments
          of principal of or any premium or interest on the notes;

     o    waive a redemption payment with respect to any note, other than a
          payment required by one of the covenants described above under the
          caption "--Repurchase at the Option of Holders;"

     o    make any change in the preceding amendment and waiver provisions; or

     o    release any Guarantor from any of its obligations under its Guarantee
          of the notes or the indenture, except in accordance with the terms of
          the indenture.

     In addition, any amendment to, or waiver of the provisions of the indenture
relating to subordination that adversely affects the rights of the holders of
the notes will require the consent of the holders of at least 75% in aggregate
principal amount of the notes then outstanding.

     Despite the above, without the consent of any holder of notes, Concentra
Operating and the trustee may amend or supplement the indenture or the notes:

     o    to cure any ambiguity, defect or inconsistency;

     o    to provide for uncertificated notes in addition to or in place of
          certificated notes;

     o    to provide for the assumption of Concentra Operating's obligations to
          holders of notes in the case of a merger or consolidation or the sale
          of all or substantially all of Concentra Operating's assets;

     o    to make any change that would provide any additional rights or
          benefits to the holders of notes or that does not adversely affect the
          legal rights under the indenture of any such holder;

     o    to comply with requirements of the Commission in order to effect or
          maintain the qualification of the indenture under the Trust Indenture
          Act of 1939, as amended;

     o    to provide for the issuance of additional notes in accordance with the
          limitations set forth in the indenture; or

     o    to allow any Subsidiary to guarantee the notes.


CONCERNING THE TRUSTEE

     If the trustee becomes a creditor of Concentra Operating or any Guarantor,
the indenture limits the trustee's right to obtain payment of claims in certain
cases, or to realize on certain property received in respect of any such claim
as security or otherwise. The trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest it must eliminate
such conflict within 90 days, apply to the Commission for permission to continue
or resign.

     The holders of a majority in principal amount of the then outstanding notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the trustee, subject to
certain exceptions. The indenture provides that in case an Event of Default
shall occur and be continuing, the trustee will be required, in the exercise of
its power, to use the degree of care of a prudent man in the conduct of his own


                                      105
<PAGE>


affairs. Subject to such provisions, the trustee will be under no obligation to
exercise any of its rights or powers under the indenture at the request of any
holder of notes, unless such holder shall have offered to the trustee security
and indemnity satisfactory to it against any loss, liability or expense.

     Anyone who receives this prospectus may obtain a copy of the indenture and
registration rights agreement without charge by writing to Concentra Operating
Corporation, 5080 Spectrum Drive, Suite 400 West Tower, Addison, TX 75001;

BOOK-ENTRY; DELIVERY; FORM AND TRANSFER

     THE GLOBAL NOTE. The certificates representing the old notes were issued,
and the certificates representing the new notes will be issued, in fully
registered form, without coupons. The old notes are represented by one or more
permanent global certificates in definitive, fully registered form without
interest coupons in an aggregate amount of $190 million. Except as described in
the next paragraph, the new notes initially will be represented by one or more
permanent global certificates in definitive, fully registered form and will be
deposited with, or on behalf of, the DTC, and registered in the name of Cede &
Co., as the DTC's nominee or will remain in the custody of the trustee pursuant
to a FAST Balance Certificate Agreement between the DTC and the trustee. If your
interest in old notes is represented by the initial global note and you fail to
tender in the exchange offer, we may issue and deliver to you a separate
certificate representing your old notes in registered form without interest
coupons.

     CERTAIN BOOK-ENTRY PROCEDURES FOR GLOBAL NOTES. The descriptions of the
operations and procedures of DTC that follow are provided solely as a matter of
convenience. These operations and procedures are solely within the control of
the respective settlement systems and are subject to change by them from time to
time. Concentra Operating takes no responsibility for these operations and
procedures and urges investors to contact DTC or its participants directly to
discuss these matters.

     DTC has advised Concentra Operating that: DTC is a limited purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the
Uniform Commercial Code and a "Clearing Agency" registered pursuant to the
provisions of the Exchange Act. DTC was created to hold securities for its
participants and facilitate the clearance and settlement of securities
transactions between participants through electronic book-entry changes in
accounts of its participants, eliminating the need for physical transfer and
delivery of certificates. Participants include securities brokers and dealers,
banks, trust companies and clearing corporations and may include certain other
organizations. Indirect access to the DTC system is available to other entities
such as banks, brokers, dealers and trust companies that clear through or
maintain a custodial relationship with a participant, either directly or
indirectly.

     Under procedures established by DTC:

     (1)  upon the issuance of the initial global certificate, DTC credited, on
          its internal system, the respective principal amount of the individual
          beneficial interests represented by such global notes to the accounts
          with DTC of the participants through which such interests are held;
          and

     (2)  ownership of beneficial interest in the global notes are shown on, and
          the transfer of that ownership is effected only through, records
          maintained by DTC or its nominees, with respect to interest of
          participants, and the records of participants and indirect
          participants, with respect to interests of persons other than
          participants.

     As long as DTC, or its nominee, is the registered holder of a global note,
DTC or such nominee, as the case may be, will be considered the sole owner and
holder of the notes represented by such global note for all purposes under the
indenture and the new notes. Except in the limited circumstances described
below, owners of beneficial interests in a global note will not be entitled to
have any portions of such global note registered in their names, and


                                      106
<PAGE>


will not receive or be entitled to receive physical delivery of notes in
definitive form and will not be considered the owners or holders of the global
note, or any notes represented by the global note, under the indenture or the
notes.

     The laws of some states require that certain persons take physical delivery
in definitive form of securities that they own. The ability to transfer
beneficial interests in a global note to such persons may be limited to that
extent. Because DTC can act only on behalf of its participants, which in turn
act on behalf of indirect participants and certain banks, the ability of a
person having beneficial interests in a global note to pledge such interest to
persons or entities that do not participate in the DTC system, or otherwise take
actions in respect of such interests, may be affected by the lack of a physical
certificate evidencing such interests.

     Payments of the principal of, premium, if any, and interest on global notes
will be made to DTC or its nominee as the registered owner of the global notes.
Neither Concentra Operating, the trustee nor any of their respective agents will
have any responsibility or liability for any aspect of the records relating to
or payments made on account of beneficial ownership interest in the global notes
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

     Concentra Operating expects that DTC or its nominee, upon receipt of any
payment of principal premium or interest in respect of a global note
representing any notes held by it or its nominee, will credit participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such global note for such notes as shown on
the records of DTC or its nominee. Concentra Operating also expects that
payments by participants to owners of beneficial interests in such global note
held through such participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts of
customers registered in "street name." Such payments will be the responsibility
of such participants. None of Concentra Operating or the trustee will be liable
for any delay by DTC or any of its participants in identifying the beneficial
owners of the notes, and Concentra Operating and the trustee may conclusively
rely on and will be protected in relying on instructions from DTC or its nominee
as the registered owner of the notes for all purposes.

     Interests in the global notes will trade in DTC's Same-Day Funds Settlement
System and secondary market trading activity in such interests will therefore
settle in immediately available funds, subject in all cases to the rules and
procedures of DTC and its participants. Transfers between participants in DTC
will be effected in accordance with DTC's procedures, and will be settled in
same-day funds.

     DTC has advised Concentra Operating that it will take any action permitted
to be taken by a holder of notes only at the direction of one or more
participants to whose accounts with DTC interests in the global notes are
credited and only in respect of such portion of the aggregate principal amount
of the notes as to which such participant or participants has or have given such
direction. However, if there is an Event of Default under the notes, DTC
reserves the right to exchange the global notes for notes in certificated form,
and to distribute such notes to its participants. See "--Certificated Notes."

     Although DTC has agreed to the foregoing procedures in order to facilitate
transfer of beneficial ownership interests in the global notes among
participants of DTC, it is under no obligation to perform or continue to perform
such procedures, and such procedures may be discontinued at any time. None of
Concentra Operating, the trustee nor any of their respective agents will have
any responsibility for the performance by DTC or its participants or indirect
participants of their respective obligations under the rules and procedures
governing its operations, including maintaining, supervising or reviewing the
records relating to or payments made on account of, beneficial ownership
interests in global notes.

     CERTIFICATED NOTES. An entire global note may be exchanged for definitive
notes in registered, certificated form without interest coupons if:

     (1)  DTC:

          (a)  notifies Concentra Operating that it is unwilling or unable to
               continue as depositary for the global notes and Concentra
               Operating then fails to appoint a successor depositary within 90
               days; or


                                      107
<PAGE>


          (b)  has ceased to be a clearing agency registered under the Exchange
               Act;

     (2)  Concentra Operating, at its option, notifies the trustee in writing
          that it elects to cause the issuance of certificated notes; or

     (3)  there will have occurred and be continuing a Default or an Event of
          Default with respect to notes.

     In any such case, Concentra Operating will notify the trustee in writing
that, upon surrender by the direct and indirect participants of their interest
in such global note, certificated notes will be issued to each person that such
direct and indirect participants and the DTC identify as being the beneficial
owner of the related notes.

     Beneficial interests in global notes held by any direct or indirect
participant may be exchanged for certificated notes upon request to DTC, by a
direct participant, for itself or on behalf of an indirect participant, to the
trustee in accordance with customary DTC procedures. Certificated notes
delivered in exchange for any beneficial interest in any global note will be
registered in the names, and issued in any approved denominations, requested by
DTC on behalf of such direct or indirect participant, in accordance with DTC's
customary procedures.

                 CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

      The summary below describes the material United States federal income tax
consequences of the exchange of old notes for new notes as of the date of this
prospectus. The discussion below is based upon the provisions of the Internal
Revenue Code of 1986, as amended, and regulations, rulings and judicial
decisions thereunder as of the date hereof, and such authorities may be
repealed, revoked or modified so as to result in federal income tax consequences
different from those discussed below. You should consult your own tax advisors
concerning the federal income tax consequences in light of their particular
situations as well as any consequences arising under the laws of any other
taxing jurisdiction.

      The exchange of old notes for new notes pursuant to the exchange offer
should not be treated as an "exchange" for federal income tax purposes, because
the new notes should not be considered to differ materially in kind or extent
from the old notes. Rather, the new notes received by you should be treated as a
continuation of your old notes. As a result, there should be no federal income
tax consequences to you if you exchange notes for new notes pursuant to the
exchange offer.

                              PLAN OF DISTRIBUTION

      Each broker-dealer that receives new notes for its own account pursuant to
the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of such new notes. This prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of new notes received in exchange for old notes where
such old notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities. We have agreed that, for a period of 90
days after the expiration date of the exchange offer, we will make this
prospectus available to any broker-dealer for use in connection with any such
resale. In addition, for a period of 90 days after the expiration date, all
dealers effecting transactions in the new notes may be required to deliver a
prospectus.

      We will not receive any proceeds from any sale of new notes by
broker-dealers. New notes received by broker-dealers for their own account
pursuant to the exchange offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the new notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or at negotiated prices. Any such resale may be
made directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such new notes. Any broker-dealer
that resells new notes that were received by it for its own account pursuant to
the exchange offer and any broker or dealer that participates in a distribution
of new notes may be deemed to be an "underwriter" within the meaning of the
Securities Act, and any profit on any such resale of new notes and any
commissions or concessions received by any such person may be deemed to be
underwriting compensation under the Securities Act. The letter of transmittal
states that a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act by acknowledging that it
will deliver and by delivering a prospectus. We have no arrangement or
understanding with any broker or dealer to distribute the new notes received in
the exchange offer.

      For a period of 90 days after the expiration date we will promptly send
additional copies of this prospectus and any amendment or supplement to this
prospectus to any broker-dealer that requests such documents in the letter of
transmittal.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

      The accompanying unaudited financial statements have been prepared by
Concentra Operating Corporation (the "Company" or "Concentra"), a wholly-owned
subsidiary of Concentra Managed Care, Inc. (the "Parent Company") pursuant to
the rules and regulations of the Securities and Exchange Commission, 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. These financial statements do not include all
disclosures associated with the annual 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 financial
statements and footnotes for the year ended December 31, 1998 included elsewhere
in this prospectus, where certain terms have been defined.


(1) RECAPITALIZATION TRANSACTION

      On March 2, 1999, Concentra Managed Care, Inc. (the "Parent Company")
announced that it had signed a definitive merger agreement to merge (the
"Merger") with Yankee Acquisition Corp. ("Yankee"), a corporation formed by
Welsh, Carson, Anderson & Stowe ("WCAS"), a 14.9% stockholder of the Company.
Concentra's board of directors unanimously approved the transaction based upon
the recommendation of its special committee of the board of directors, which was
formed on October 29, 1998 to evaluate strategic alternatives in response to
several unsolicited expressions of interest regarding the possible acquisition
of some or all of the Company's common stock. On March 24, 1999, Concentra
entered into an amended and restated agreement and plan of merger with Yankee.

     On August 17, 1999, Concentra Managed Care, Inc. merged with Yankee. As a
result of the Merger, each outstanding share of Concentra Managed Care, Inc.
common stock was converted into the right to receive $16.50 in cash. WCAS
acquired approximately 86%, funds managed by Ferrer Freeman Thompson & Co., LLC
("FFT") acquired approximately 7% and other investors acquired approximately 7%
of the post-merger shares of common stock of Concentra Managed Care, Inc.,
Concentra Operating Corporation's parent company, for $16.50 per share.
Simultaneous with the right to receive cash for shares, Yankee merged with and
into Concentra Managed Care, Inc., the surviving entity, and Concentra Managed
Care, Inc. contributed all of it operating assets and liabilities with the
exception of $110,000,000 of 14% Senior Discount Debentures due 2010 and
$327,750,000 of 6.0% and 4.5% Convertible Subordinated Notes to Concentra
Operating Corporation (the "Company" or "Concentra"), a wholly-owned subsidiary
of Concentra Managed Care, Inc. The 6.0% and 4.5% Convertible Subordinated Notes
were substantially retired during the quarter as a result of the Merger. The
Merger was accounted for as a recapitalization transaction, with no changes to
the basis of assets or liabilities.

      The transaction was valued at approximately $1,100,000,000, including the
refinancing of $327,737,000 of the 6.0% and 4.5% Convertible Subordinated Notes
that were tendered during the quarter. To finance the acquisition of Concentra
Managed Care, Inc., WCAS, FFT and other investors invested approximately
$423,679,000 in equity financing, including the value of shares already owned by
Welsh Carson, and $110,000,000 of 14% Senior Discount Debentures due 2010 with
warrants issued by Concentra Managed Care, Inc. exercisable into its common
shares. Concentra Operating Corporation received from various lenders
$375,000,000 in term loans, a $100,000,000 revolving credit facility to replace
the pre-merger revolving credit facility and $190,000,000 of 13% Series A Senior
Subordinated Notes due 2009. Concentra's excess cash balances funded merger and
financing related fees and expenses and related employee stock option exercises
and cancellation payments.

      Concentra incurred $18,000,000 of deferred financing fees for the issuance
of the Merger related financing and recorded a non-recurring charge of
$54,419,000 in the third quarter of 1999 incurred primarily for fees, expenses
and other non-recurring charges associated with the Merger. The utilization of
this non-recurring charge through September 30, 1999, was approximately
$15,466,000 for professional fees and services, $13,506,000 for employee related
stock option exercises and cancellations, $10,500,000 for a WCAS transaction
fee, $5,493,000 in non-cash charges for deferred compensation expense related to
the accelerated vesting and issuance of 210,000 shares of restricted stock and
$1,666,000 of other non-recurring charges. At September 30, 1999, approximately
$7,788,000 of the non-recurring charge remains for professional fees and
services, employee related stock options and other non-recurring charges.

(2) BASIS OF PRESENTATION

      The accompanying consolidated financial statements as of December 31, 1998
and September 30, 1999 and for the three and nine months ended September 30,
1998 and 1999 and related footnotes reflect the operating results of Concentra
Managed Care, Inc. through August 17, 1999 and the operating results of
Concentra Operating Corporation from August 18, 1999 through September 30, 1999.
Concentra Operating Corporation is a wholly-owned subsidiary of Concentra
Managed Care, Inc. and they are considered entities under common control,
therefore, combined financial statements have been presented. Earnings per share
has not been reported for all periods presented, as Concentra Operating
Corporation is a wholly-owned subsidiary of Concentra Managed Care, Inc. and has
no publicly held shares.

      The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS 130")
effective in the second quarter of 1998. SFAS 130 establishes standards for
reporting comprehensive income and its components in the consolidated financial
statements. The Company's reported net income for the three and nine months
ended September 30, 1998 and 1999 does not differ from comprehensive income as
defined in SFAS 130.


(3) CHANGE IN ESTIMATE

      The Company has historically amortized goodwill over periods ranging from
30 to 40 years. Effective January 1, 1999, the Company changed its policy, on a
prospective basis, with respect to amortization of goodwill. All existing and
future goodwill will be amortized over a period not to exceed 25 years. Had the
Company adopted this policy at the beginning of 1998, amortization for the three
and nine months ended September 30, 1998 and for the year ended December 31,
1998 would have increased approximately $800,000, $2,400,000 and $3,300,000,
respectively. As of September 30, 1999, net intangible assets consisted of the
following:

(4) RECENT ACQUISITIONS AND NON-RECURRING CHARGES

      On February 24, 1998, the Company acquired all of the outstanding common
stock of Preferred Payment Systems, Inc. ("PPS") of Naperville, Illinois, in
exchange for approximately 7,100,000 shares of Concentra common stock, the
assumption of PPS options totaling approximately 580,000 shares of Concentra
common stock, the payment of $15,047,000 in cash to dissenting PPS shareholders,
and the assumption of approximately $49,000,000 of debt which was repaid at the
time of the merger (see Note 5). This transaction was accounted for as a pooling
of interests. PPS, founded in 1990, is a provider of specialized cost
containment and outsourcing services for healthcare payors.

      In the first quarter of 1998, the Company recorded a non-recurring charge
of $12,600,000 primarily associated with the merger of PPS. The utilization of
this charge through September 30, 1999, was approximately $5,261,000 for
professional fees and services, $2,578,000 in costs associated with personnel
reductions, $1,139,000 in facility consolidations and closings, $1,627,000
associated with the write-off of deferred financing fees on PPS indebtedness
retired and $1,520,000 of other non-recurring costs. At September 30, 1999,
approximately $475,000 of the non-recurring charge remains primarily related to
remaining facility lease obligations.

      In the fourth quarter of 1998, the Company recorded a non-recurring charge
of $20,514,000 primarily associated with the reorganization of its Managed Care
Services division to improve efficiency through facility consolidations and
related headcount reductions, an impairment loss on the intangible related to an
acquired contract and costs associated with settling claims on other expired
contracts. The utilization of this charge through September 30, 1999 was
approximately $7,416,000 in charges related to an impairment loss on the
intangible related to an acquired contract, $3,945,000 in costs associated with
personnel reductions, $351,000 in costs associated with settling claims on other
expired contracts and $2,824,000 in facility consolidations and $85,000 of other
non-recurring costs. At September 30, 1999, approximately $5,893,000 of the
non-recurring charge remains primarily related to remaining facility lease
obligations and costs associated with settling claims on certain other expired
contracts.

     In the third quarter of 1999, the Company recorded a non-recurring charge
of $54,419,000 primarily for fees, expenses and other non-recurring charges
associated with the Merger. The utilization of this non-recurring charge through
September 30, 1999, was approximately $15,466,000 for professional fees and
services, $13,506,000 for employee related stock option exercises and
cancellations, $10,500,000 for a WCAS transaction fee, $5,493,000 in non-cash

non-recurring charge remains for professional fees and services, employee
related stock option exercises and other non-recurring charges..

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

     On August 17, 1999, the Company entered into a $475,000,000 Credit
Agreement (the "Credit Facility") with a consortium of banks, providing for
$375,000,000 in term loans and a $100,000,000 revolving credit facility (the
"Revolving Credit Facility"). The $375,000,000 in term loans were issued as a
$250,000,000 term loan (the "Tranche B Term Loan") and a $125,000,000 term loan
(the "Tranche C Term Loan") bearing interest at the Applicable Base Rate, as
defined, plus 2.25% and 2.50%, respectively, or the Eurodollar Rate, as defined,
plus 3.25% and 3.50%, respectively. The Tranche B Term Loan matures on June 30,
2006 and requires quarterly principal payments of $625,000 through June 30, 2005
and $58,750,000 for each of the remaining four quarters. The Tranche C Term Loan
matures on June 30, 2007 and requires quarterly principal payments of $312,500
through June 30, 2006 and $29,062,500 for each of the remaining four quarters.
The $100,000,000 Revolving Credit Facility matures on August 17, 2005.
Borrowings under the Revolving credit facility are payable, at the Company's
option at ABR plus 1.75% or the Eurodollar Rate plus 2.75%. Commitment fees on
the unused revolver borrowings are at 0.5% per annum. The Company had borrowings
outstanding under the Revolving Credit Facility of $1,500,000 at September 30,
1999.

      The $190,000,000 13% Series A Senior Subordinated Notes (the "13%
Subordinated Notes") due August 15, 2009 are general unsecured indebtedness with
semi-annual interest payments due on February 15 and August 15 commencing on
February 15, 2000. The Company can redeem the 13% Subordinated Notes on or after
August 15, 2004 at 106.5% of the principal amount with the redemption premium
decreasing annually to 100.0% of the principal amount on August 15, 2008.

      The Credit Facility and 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's obligations under the Senior Credit Facility are secured by a pledge
of stock in the Company's subsidiaries.

      The Company was in compliance with its covenants, including its financial
covenant ratio tests, in the third quarter of 1999.

      In December 1996, the Company issued $97,750,000 of 6.0% Convertible
Subordinated Notes due 2001. On September 17, 1997, the Company entered into a
$100,000,000 Senior Credit Facility with a syndicate of five banks. On February
23, 1998, the Company signed an amendment to expand the Company's borrowing
capacity under the Senior Credit Facility to $200,000,000 under similar terms
and conditions in order to finance the repayment of debt associated with its
acquisition of PPS. On February 24, 1998, the Company acquired PPS and retired
$49,000,000 of PPS' outstanding indebtedness. PPS' 5.0% Convertible Subordinated
Notes due August 2006 converted into 2,721,904 shares of Concentra Managed Care,
Inc. common stock. In March and April 1998, the Company issued $230,000,000 4.5%
Convertible Subordinated Notes due 2003 and the Senior Credit Facility borrowing
capacity was reduced to the original $100,000,000 amount. On August 17, 1999,
the Senior Credit Facility was replaced with the Revolving Credit Facility and
substantially all of the 6.0% and 4.5% Convertible Subordinated Notes were
retired through debt tender offers during the quarter in connection with the
Merger.


(6) 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 are the reportable segments:

      Health Services manages occupational healthcare centers at which it
provides support personnel, marketing, information systems and management
services to its affiliated physicians. Health Services owns all the operating
assets of the occupational healthcare centers, including leasehold interests and
medical equipment.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

      Specialized Cost Containment services include first report of injury,
utilization management (precertification and concurrent review), retrospective
medical bill review, telephonic case management, specialized preferred provider
organization ("PPO") network access, independent medical examinations ("IMEs"),
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 Field Case Management and Cost Containment 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 41.6% and 42.5% of total Managed Care Services revenue for the three
and nine months ended September 30, 1999, respectively.

      There has not been a material change in the composition of segment
identifiable assets as of September 30, 1999 as compared to December 31, 1998
amounts reported in the Company's financial statements for the year ended
December 31, 1998 included elsewhere in this prospectus. Revenues from
individual customers, revenues between business segments and revenues, operating
profit and identifiable assets of foreign operations are not significant.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders and Board of Directors of
Concentra Managed Care, Inc.:

We have audited the accompanying consolidated balance sheets of Concentra
Managed Care, Inc. (a Delaware corporation) as of December 31, 1997 and 1998,
and the related consolidated statements of operations, cash flows and
stockholders' equity for each of the three years in the period ended December
31, 1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Concentra Managed Care, Inc. as
of December 31, 1997 and 1998, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1998, in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1) BASIS OF PRESENTATION

      On August 29, 1997, Concentra Managed Care, Inc. ("Concentra" or the
"Company"), a Delaware corporation, 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 Company recorded a non-recurring
charge of $38,625,000 in the third quarter of 1997 associated with the 1997
Merger. The utilization of this charge through December 31, 1998, was
approximately $11,569,000 for professional fees and services, $16,216,000 in
costs associated with personnel reductions and the consolidation of CRA's and
OccuSystems' employee benefits, $5,945,000 in facility consolidations and
closings, $2,541,000 for the write-off of start-up costs and $2,354,000 of other
charges. At December 31, 1997, approximately $7,527,000 of the non-recurring
charge remains primarily related to personnel related charges and facility
consolidations and closings.

      On February 24, 1998, the Company acquired all of the outstanding common
stock of Preferred Payment Systems, Inc. ("PPS") of Naperville, Illinois, in
exchange for approximately 7,100,000 shares of Concentra common stock, the
assumption of PPS options totaling approximately 580,000 shares of Concentra
common stock, the payment of approximately $15,047,000 in cash to dissenting PPS
shareholders and the assumption of approximately $49,000,000 of debt which was
repaid at the time of the merger. This merger was accounted for as a pooling of
interests. In the first quarter of 1998, the Company recorded a non-recurring
charge of $12,600,000 primarily associated with the merger of PPS. The
utilization of this charge through December 31, 1998, was approximately
$5,136,000 for professional fees and services, $2,355,000 in costs associated
with personnel reductions, $746,000 in facility consolidations and closings,
$1,627,000 associated with the write-off of deferred financing fees on PPS
indebtedness retired and $1,264,000 of other non-recurring costs. At December
31, 1998, approximately $1,472,000 of the non-recurring charge remains primarily
related to remaining facility lease obligations. PPS, founded in 1990, is a
provider of retrospective bill review services for the group healthcare market.

      In the fourth quarter of 1998, the Company recorded a non-recurring charge
of $20,514,000 primarily associated with the reorganization of its Managed Care
Services division to improve efficiency through facility consolidations and
related headcount reductions, to recognize an impairment loss on the intangible
related to an acquired contract and costs associated with settling claims on
other expired contracts. The utilization of this charge through December 31,
1998, was approximately $7,416,000 in charges related to the recognition of an
impairment loss on the intangible related to an acquired contract, $2,490,000 in
costs associated with personnel reductions and $1,140,000 in facility
consolidations. At December 31, 1998, approximately $9,468,000 of the
nonrecurring charge remains primarily related to remaining facility lease
obligations and costs associated with settling claims on other expired
contracts.

      The financial statements as of December 31, 1997 and for the years ended
December 31, 1996 and 1997 have been restated to reflect the merger of PPS in
accordance with Accounting Principles Board Opinion No. 16, "Business
Combinations" ("APB 16").


(2) SIGNIFICANT ACQUISITIONS

      Managed Care Services has experienced a significant amount of its growth
by virtue of the acquisitions of FOCUS HealthCare Management, Inc. ("FOCUS"),
Prompt Associates, Inc. ("PROMPT"), First Notice Systems, Inc. ("FNS"), About
Health, Inc. ("ABOUT HEALTH") and several other smaller acquisitions. Health
Services has also experienced a significant amount of its growth from the
acquisition of practices, including the acquisition of 16 occupational medical
centers and contracts to manage four additional medical centers from Vencor,
Inc. ("VMC").


                                      F-18
<PAGE>

      On April 2, 1996, the Company purchased FOCUS for $21,000,000 in cash.
FOCUS, based in Brentwood, Tennessee, has built and maintains one of the
nation's largest workers' compensation preferred provider organization ("PPO")
networks and had annual revenues of approximately $9,900,000 for the year ended
December 31, 1995.

      On October 29, 1996, the Company purchased PROMPT for $30,000,000 in cash.
PROMPT, which is based in Salt Lake City, Utah, is one of the leading providers
of hospital bill audit services to the group health payor community for claims
that fall outside of an indemnity carrier's, third-party administrator's ("TPA")
or health maintenance organization's ("HMO") network of hospital or outpatient
facilities and had annual revenues of approximately $10,000,000 for the year
ended December 31, 1995.

      On June 4, 1997, the Company purchased FNS for $40,000,000 in cash. FNS,
based in Boston, Massachusetts, is a leading provider of outsourced call
reporting for first notice of loss/injury to the automobile insurance and
workers' compensation industries and had annual revenues of approximately
$9,000,000 for the year ended December 31, 1996.

      PPS acquired ABOUT HEALTH in a two-step transaction on August 1, 1997 and
October 31, 1997 for $25,800,000 in cash and $9,733,000 in equity. ABOUT HEALTH,
based in Rockville, Maryland, is a provider of specialized cost containment and
outsourcing services for healthcare payors and had annual revenues of
approximately $10,000,000 for the year ended December 31, 1996.

      On September 30, 1997, the Company purchased 16 occupational medical
centers and the management of four additional medical centers from VMC for
approximately $27,000,000 in cash. These medical centers had annual revenues of
approximately $23,000,000 for the year ended December 31, 1996.

      The acquisitions of FOCUS, PROMPT, FNS, ABOUT HEALTH and VMC have been
accounted for by the Company as purchases whereby the basis for accounting for
their assets and liabilities are based upon their fair values at the dates of
acquisition. The excess of the purchase price over fair value of net assets
acquired (goodwill and assembled workforce and customer lists, if applicable)
for the FOCUS, PROMPT, FNS, ABOUT HEALTH and VMC acquisitions was $19,900,000,
$29,550,000, $37,001,000, $34,291,000 and $29,585,000, respectively. None of
these acquisitions were significant in relation to the Company's consolidated
financial statements and, therefore pro forma financial information has not been
presented. Goodwill is being amortized over thirty to forty year periods and
assembled workforce and customer lists are being amortized over five and
seven-year periods, respectively.


(3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a) CONSOLIDATION

      The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. Investments in certain joint ventures with
less than a 51% ownership interest are accounted for on a equity basis and,
accordingly, consolidated income includes the Company's share of their income.
All significant intercompany accounts and transactions are eliminated in
consolidation.

      Physician and physical therapy services are provided at the Health
Services centers under management agreements with affiliated physician
associations (the "Physician Groups"), which are organized professional
corporations that hire licensed physicians and physical therapists to provide
medical services to the centers' patients. Health Services has a nominee
shareholder relationship with the Physician Groups as defined in EITF 97-2,
Application of APB Opinion No. 16 and FASB Statement No. 94 to Physician
Practice Entities, and as a result, the financial statements of the Physician
Groups are consolidated. Specifically:

      o    Health Services can at all times establish or effect change in the
           nominee shareholder;

      o    Health Services can cause a change in the nominee shareholder an
           unlimited number of times;

      o    Health Services has sole discretion as to the choice of a new nominee
           shareholder;

      o    Health Services has sole discretion without cause to establish or
           change the nominee shareholders;


                                      F-19
<PAGE>

      o    Health Services and the Physician Groups would incur no more than a
           nominal cost to cause a change in the nominee shareholder; and,

      o    Neither Health Services nor the Physician Groups are subject to any
           significant adverse impact upon a change in the nominee shareholder.

      The Company's management fees from the Physician Groups are calculated as
collected revenue net of compensation, benefits and other expenses incurred by
the Physician Groups.


(b) CASH AND CASH EQUIVALENTS

      The Company considers all highly liquid debt instruments purchased with
original maturities of three months or less to be cash equivalents. The carrying
amount approximates fair value due to the short maturity of those instruments.


(c) REVENUE RECOGNITION

      The Company recognizes revenue primarily as services have been rendered
based on time and expenses incurred. A certain portion of the Company's revenues
are derived from fee schedule auditing which is based on the number of charges
reviewed and based on a percentage of savings achieved for the Company's
customers. In these circumstances, the customer is obligated to pay the Company
when the services have been rendered and the savings identified. During the fee
schedule audit process (i.e., medical bill review), each bill reviewed and
audited is returned to the customer accompanied by an Explanation of Benefit
("EOB"). The EOB details the total savings with respect to the bill being
reviewed as well as the amount owed to the Company as a percentage of savings
identified and the line charge associated with the bill being reviewed.

      The Company's Health Services division's services consist of two primary
components : (i) workers' compensation injury care and related services; and
(ii) non-injury healthcare services related to employer needs or statutory
requirements. The workers' compensation injury care and related services'
provider reimbursement methods vary on a state-by-state basis. Of the 25 states
in which the Company currently operates occupational healthcare centers, 21 have
fee schedules pursuant to which all healthcare providers are uniformly
reimbursed. The fee schedules are set by each state and generally prescribe the
maximum amounts that may be reimbursed for a designated procedure. In the four
states without fee schedules, healthcare providers are reimbursed based on
usual, customary and reasonable ("UCR") fees charged in the particular state in
which the services are provided. Billing for services in states with fee
schedules are included in revenues net of allowance for estimated differences
between list prices and allowable fee schedule rates. Adjustments to the
allowance based on final payment from the states are recorded upon settlement.
The Company records the net revenue amount as accounts receivable.

      The Company's total contractual allowances offset against revenues during
the years ended December 31, 1998, 1997 and 1996 were $16,095,000, $14,718,000
and $3,680,000, respectively.

      Insurance claims are screened by PPS and PROMPT prior to the insurance
company's internal review procedures to determine if the claims should be
further negotiated or are payable by the insurance company. During the insurance
company's review process, some claims have pre-existing PPO or HMO arrangements,
or other pre-existing conditions and disqualifying situations. When these
situations occur, a refund (chargeback) is requested for the amounts paid
(invoiced) on these claims. PPS and PROMPT's policies are to record a sales
allowance as an offset to revenues and accounts receivable based upon the
historical tracking of discounts and chargebacks at the time the claims are
modeled. A portion of the allowance for doubtful accounts attributable to PPS
and PROMPT is based on historical experience of ineligible claims which are
either charged back or given a negotiated discount. PPS and PROMPT utilize
several methods to project unpresented discounts and chargebacks including a
tracking of the actual experience of contractual discounts. Other factors that
affect collectability and bad debts for each service line are also evaluated and
additional allowance amounts are provided as necessary.

      Accounts receivable at December 31, 1997 and 1998 include $4,500,000 of
unbilled accounts receivable relating to services rendered during the period but
not invoiced until after the period-end. These unbilled accounts


                                      F-20
<PAGE>

receivable relate primarily to field case management services, which are billed
on an hourly basis, whereby the Company has not yet provided a sufficient amount
of services to warrant the generation of an invoice. The customers are obligated
to pay for the services once performed. The Company estimates unbilled accounts
receivable by tracking and monitoring its historical experience.


(d) DEPRECIATION

      The Company provides for depreciation on property and equipment using
straight-line and accelerated methods by charges to operations in amounts that
allocate the cost of depreciable assets over their estimated lives as follows:

ASSET CLASSIFICATION                         ESTIMATED USEFUL LIFE
- ----------------                               ------------------
Furniture and fixtures                              7 Years
Office and computer equipment                      3--7 Years
Buildings and improvements                        30--40 Years
Leasehold improvements           The shorter of the life of lease or asset life


(e) INTANGIBLE ASSETS

      The value of goodwill, assembled workforces and customer lists are
recorded at cost at the date of acquisition. Through December 31, 1998 goodwill,
including any excess arising from earn-out payments, was being amortized on a
straight-line basis over 30 to 40-year periods in accordance with Accounting
Principles Board Opinion No. 17 ("APB No. 17"), "Intangible Assets". Effective
January 1, 1999, the Company changed its policy, on a prospective basis, with
respect to the amortization of goodwill. All existing and future goodwill will
be amortized over a period not to exceed 25 years. Had the Company adopted this
policy at the beginning of 1998, amortization for 1998 would have increased by
approximately $3,300,000 and diluted earnings per share would have been $0.42.
As of December 31, 1998, net intangible assets consisted of goodwill, customer
lists and assembled workforce. The Company believes that the life of the core
businesses acquired and the delivery of occupational healthcare services is
indeterminate and likely to exceed 25 years. The assembled workforces and
customer lists are being amortized over five- and seven-year periods,
respectively. As of December 31, 1997 and 1998, the Company has recorded
accumulated amortization on intangible assets of $29,834,000 and $37,938,000
respectively.

      Subsequent to an acquisition, the Company continually evaluates whether
later events and circumstances have occurred that indicate that the remaining
balance of goodwill may not be recoverable or that the remaining useful life may
warrant revision. When factors indicate that goodwill should be evaluated for
possible impairment, the Company uses an estimate of the related operating
unit's undiscounted cash flows over the remaining life of the goodwill and
compares it to the operating unit's goodwill balance to determine whether the
goodwill is recoverable or if impairment exists, in which case an adjustment is
made to the carrying value of the asset to reduce it to its fair value based
upon the present value of the future cash flows. When an adjustment is required
the Company evaluates the remaining goodwill amortization using the factors
outlined in APB No. 17.


(f) DEFERRED FINANCE COSTS

      The Company has capitalized costs associated primarily with the 6% and
4.5% Convertible Subordinated Notes and the PPS indebtedness (written-off at the
time of the merger and retirement of PPS indebtedness) and is amortizing these
as interest expense over the life of the notes. Included in other assets at
December 31, 1997 and 1998 were deferred finance costs, net of accumulated
amortization, of $4,515,000 and $7,592,000, respectively.

(h) INVESTMENTS IN JOINT VENTURES

      Investments in the net assets of joint ventures accounted for under the
equity method amounted to $3,937,000 and $3,839,000 at December 31, 1997 and
1998, respectively. For the year ending December 31, 1997 and 1998, revenue for
these entities was $4,561,000 and $5,724,000, gross profit was $950,000 and
$919,000 and net income was $287,000 and $338,000, respectively. Total assets
for the joint ventures were $4,277,000 and $4,306,000 as of December 31, 1997
and 1998, respectively.


(i) SELF INSURANCE

      Company is partially insured for workers' compensation, physician medical
malpractice, automobile and certain employee health benefits. The Company's
self-insurance retention liability on a per claim basis ranges from $100,000 to
$250,000. Liabilities in excess of these amounts are the responsibility of the
insurer. The Company's policy is to accrue amounts up to the insurance carriers'
reserve requirements on a claim-by-claim basis and an estimate for claims
incurred but not yet reported.


(j) DEFERRED START-UP COSTS

      Prior to the 1997 Merger, Health Services capitalized the start-up costs
associated with the internal development of its medical centers until
operational and would amortize these costs over a three-year period. The
American Institute of Certified Public Accountants issued Statement of Opinion
98-5, "Accounting for Start Up Costs" in April 1998, to change the accounting
and reporting treatment of start-up costs to require start-up costs to be
expensed as incurred. As a result of this pending change in accounting
principle, the Company wrote-off deferred start-up costs of approximately
$2,541,000 and included this in the third quarter of 1997 non-recurring charge.

(k) FOREIGN CURRENCY TRANSLATION

      All assets and liabilities of the Company's Canadian offices are
translated at the year-end exchange rate, while revenues and expenses are
translated at the average exchange rate for the year. Cumulative translation
adjustments were immaterial for the years ended December 31, 1996, 1997 and
1998.


(l) USE OF ESTIMATES

      The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates.


(m) RECLASSIFICATIONS

      Certain amounts previously reported in CRA's and OccuSystems' 1996
consolidated financial statements and PPS' 1996 and 1997 consolidated financial
statements have been reclassified to conform to the presentation in the 1998
consolidated financial statements.


(n) NEW ACCOUNTING PRONOUNCEMENTS

      In the first quarter of 1998, the Company adopted the provisions of
Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive
Income" ("SFAS 130"). Comprehensive income for the Company includes unrealized
gains on marketable securities in addition to net income as reported in the
Company's Consolidated Statements of Stockholders' Equity and in the
Stockholders' Equity section of the Company's Consolidated Balance Sheets.

      In 1998, the Company adopted the provisions of Statement of Financial
Accounting Standards No. 131, "Disclosures about Segments of an Enterprise and
Related Information" ("SFAS 131"). SFAS 131 requires the reporting of financial
and descriptive information about a company's reportable operating segments.
Operating segments are components of an enterprise's separate financial
information that is evaluated regularly by the chief operating decision maker in
deciding how to allocate resources and in assessing performance of that
component. The statement requires reporting segment profit or loss, certain
specific revenue and expense items, and segment assets. See Note 13--Segment
Information for disclosure


(4) PRO FORMA NET INCOME AND PRO FORMA EARNINGS PER SHARE

      Pro forma net income and basic and diluted pro forma earnings per share
for the years ended December 31, 1996 and 1997 have been calculated as if the
merger of PPS had been subject to federal and state income taxes for the entire
period, based upon an effective tax rate indicative of the statutory rates in
effect. Prior to its merger, PPS elected to be taxed as an S corporation, and
accordingly, was not subject to federal and state income taxes in certain
jurisdictions.

      The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128"), which
supersedes Accounting Principles Board Opinion No. 15. SFAS 128 establishes new
accounting standards for the presentation of earnings per share whereby primary
earnings per share is replaced with "Basic Earnings Per Share" and fully diluted
earnings per share is now called "Diluted Earnings Per Share". In accordance
with SFAS 128, Basic Earnings Per Share has been computed by dividing reported
net income by weighted average common shares outstanding and Diluted Earnings
Per Share has been computed assuming, if dilutive, the conversion of the
Company's convertible notes and the elimination of the related interest expense
and the exercise of stock options, net of their related income tax effect.

- ----------------
(1)   Pro forma net income and basic and diluted pro forma earnings per share
      for the years ended December 31, 1996 and 1997 have been calculated as if
      PPS had been subject to federal and state income taxes for the entire
      period, based upon an effective tax rate indicative of the statutory rates
      in effect. Prior to its merger with the Company, PPS elected to be taxed
      as an S corporation and, accordingly, was not subject to federal and state
      income taxes in certain jurisdictions.

(2)   Excludes common stock equivalents of 3,291,243 shares of Common Stock
      related to the 6% Convertible Subordinated Notes issued in December 1996
      and 5,575,758 shares of Common Stock related to the 4.5% Convertible
      Subordinated Notes issued in March and April 1998 as they are
      anti-dilutive for the applicable years presented.


(5) REVOLVING CREDIT FACILITIES

      On September 17, 1997, the Company entered into the $100,000,000 Senior
Credit Facility with a syndicate of five banks ("Senior Credit Facility"),
replacing the $60,000,000 Managed Care Services Credit Facility, ("MCS Credit
Facility") and the $60,000,000 Health Services Credit Facility, ("HS Credit
Facility"). The Senior Credit Facility matures on September 17, 2002. Interest
on borrowings under the Senior Credit Facility is payable, at the Company's
option, at the higher of the bank's prime rate of interest or the federal funds
rate plus an additional percentage of 0.5%, or LIBOR plus an additional
percentage of up to 1.25%, depending on certain financial criteria. The Company
is required to pay a commitment fee of 0.125% to 0.25% per annum, depending on
certain financial criteria, on the unused portion of the Senior Credit Facility.

      On February 23, 1998, the Company signed an amendment to expand the
Company's borrowing capacity under the Senior Credit Facility to $200,000,000
under similar terms and conditions in order to finance the repayment of
$49,000,000 of PPS outstanding indebtedness (the PPS Credit Facility and 10%
Subordinated Notes). On March 11, 1998, the Senior Credit Facility borrowing
capacity was reduced to the original $100,000,000 amount.


                                      F-24
<PAGE>

      The Senior Credit Facility contains 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 Senior Credit Facility, the Company is also
required to satisfy certain financial covenants, such as cash flow, capital
expenditures and other financial ratio tests including fixed charge coverage
ratios. The Company's obligations under the Senior Credit Facility are secured
by a pledge of stock in the Company's subsidiaries.

      As a result of the fourth quarter 1998 non-recurring charge, the Company
was not in compliance with certain leverage ratio covenants under the Senior
Credit Facility in the fourth quarter of 1998 and the Company expects it will
not be in compliance with those covenants in the first quarter of 1999. The
Company received a waiver on all financial covenants through the first quarter
of 1999. The Company does not have any borrowings outstanding under the Senior
Credit Facility and does not anticipate the need to borrow under the Senior
Credit Facility for the next twelve months.

      At December 31, 1997, the Company had borrowings under the Senior Credit
Facility of $49,000,000, at an average rate of interest of 6.94%. At December
31, 1998, the Company had no borrowings and $3,050,000 of letters of credit
outstanding under the Senior Credit Facility. For the years ended December 31,
1996, 1997 and 1998, the weighted average borrowings under these revolving
credit facilities were $8,184,000, $9,615,000 and $14,205,000, respectively, and
the weighted average interest rates were 6.94%, 7.31% and 7.69%, respectively.

      As of December 31, 1998 and 1997, accrued interest was $3,276,000 and
$867,000 respectively.

      On March 11, 1998, the Company issued a new issue of $200,000,000
aggregate principal amount of 4.5% Convertible Subordinated Notes due March 15,
2003 (the "4.5% Convertible Subordinated Notes"). On April 6, 1998, the
underwriters exercised the $30,000,000 overallotment provision. The 4.5%
Convertible Subordinated Notes will be convertible into 5,575,758 shares of
Common Stock, at the option of the holder, at a conversion price of $41.25 per
share, representing a conversion premium of 25% over the previous day's closing
price. The 4.5% Convertible Subordinated Notes are general unsecured obligations
of the Company ranking equal in right of payment with the 6% Convertible
Subordinated Notes and all other unsecured indebtedness of the Company. In
addition, the Company is a holding company that conducts all of its operations
through subsidiaries, and the 4.5% Convertible Subordinated Notes and the 6%
Convertible Subordinated Notes are structurally subordinate to all obligations
of the Company's subsidiaries. The 4.5% Convertible Subordinated Notes were sold
through a private place-


                                      F-25
<PAGE>

ment under Rule 144A of the Securities Act of 1933, as amended and have similar
terms and conditions as the 6% Convertible Subordinated Notes.

      In December 1996, Health Services issued an aggregate of up to $97,750,000
in principal amount of 6% Convertible Subordinated Notes ("6% Convertible
Subordinated Notes"). The 6% Convertible Subordinated Notes will be convertible
into 3,291,243 shares of Common Stock at the initial conversion price of $29.70
per share (equivalent to a conversion rate of 33.67 shares per $1,000 principal
amount of 6% Convertible Subordinated Notes), subject to adjustment in certain
events. The notes are convertible into Common Stock at the option of the holder
on or after February through December 2001. The 6% Convertible Subordinated
Notes will mature on December 15, 2001 with interest being payable semi-annually
on June 15 and December 15 of each year, commencing on June 15, 1997.

      On August 31, 1996, PPS completed a series of transactions involving funds
managed by a private equity firm and senior officers of PPS (the "1996
Transaction"). In connection with the 1996 Transaction, the private equity firm
invested $17,000,000 to acquire $10,000,000 in 5% Convertible Subordinated Notes
due August 2006 (the "5% Convertible Subordinated Notes") and $7,000,000 of 10%
Subordinated Notes due August 2003 (the "10% Subordinated Notes"). PPS also
entered into a credit facility with a syndicate of two banks, which provided for
$25,000,000 of senior debt, $20,000,000 of which was in the form of a term loan
and $5,000,000 of which was available pursuant to a line of credit. PPS, in
turn, used the net proceeds from these financing transactions to make
distributions to its stockholders in an aggregate amount of approximately
$36,000,000.

      On July 31, 1997, in connection with the acquisition of ABOUT HEALTH (see
Note 2), PPS entered into an amended and restated credit facility (as so amended
and restated, the "PPS Term Loan") to increase the term loan portion by $26.5
million. The Company is obligated to make quarterly principal and interest
payments on the term loan (bearing interest of 8.0% and 7.8% at December 31,
1996 and 1997, respectively) and quarterly interest payments on the line of
credit (bearing interest at 9.25% and 9.0% at December 31, 1996 and 1997,
respectively).

      The 10% Subordinated Notes bear interest at 10% per annum, payable
quarterly. Beginning February 2002, the Company is required to make semiannual
principal payments on the 10% Subordinated Notes of $1.7 million. Under the 10%
Subordinated Loan Agreement, the Company is required to prepay the 10%
Subordinated Notes in whole upon a qualifying public offering, sale of the
Company, or other change in control, as defined.

      The 5% Convertible Subordinated Notes are convertible at any time by the
holder into 10,000 shares of PPS Redeemable Preferred Stock and 10,000 shares of
PPS Convertible Preferred Stock. The 5% Convertible Subordinated Notes mature in
August 2006, subject to the right of the holders to accelerate the maturity of
the 5% Convertible Subordinated Notes upon a public equity offering, a
qualifying sale of the Company, or a merger resulting in a change in majority
ownership of the Company. The 5% Convertible Subordinated Notes bear interest at
5%, 2% being payable quarterly and 3% being deferred and payable upon redemption
or maturity.

      On February 24, 1998, in connection with the merger of PPS, Concentra
repaid $49,000,000 of PPS indebtedness (the PPS Term Loan and 10% Subordinated
Notes) and the 5% Convertible Subordinated Notes were converted into 2,721,904
shares of Concentra Common Stock.


(7) FINANCIAL INSTRUMENTS

      Effective December 31, 1995, the Company adopted Statement of Financial
Accounting Standards No. 107, "Disclosures About Fair Value of Financial
Instruments". This statement requires entities to disclose the fair value of
their financial instruments, both assets and liabilities, and off- balance
sheet, for which it is practicable to estimate fair value. The following
describes the methods and assumptions that were used to estimate the fair value
of each class of financial instruments for which it is practicable to estimate
that value.

      The Company's marketable securities are held as available for sale in
accordance with the provisions of Statement of Financial Accounting Standards
No. 115, "Accounting for Certain Investments in Debt and Equity Securities".

</TABLE>

      The average maturity of the Company's marketable securities as of December
31, 1998 was approximately 20 months.

      Financial instruments that potentially subject the Company to
concentrations of credit risk are accounts receivable and marketable securities.
Mitigating factors related to the Company's accounts receivable are that they
are spread over a large customer base and various product lines the Company
offers. Further, the Company does monitor the financial performance and credit
worthiness of its large customers. Mitigating factors related to the Company's
marketable securities are that they are primarily U.S. government securities and
corporate bonds and notes, with strong credit ratings. The Company limits the
amount of its investment exposure as to institution, maturity and investment
type.

      The carrying amounts of cash and cash equivalents, accounts receivable,
other current assets, accounts payable, and accrued expenses approximate fair
value because of the short maturity of those instruments. The credit facilities
approximate fair value primarily due to the floating interest rates associated
with those debt instruments.

      The fair value of the Company's 6% Convertible Subordinated Notes was
$125,120,000 and $83,088,000 as of December 31, 1997 and 1998 and the Company's
4.5% Convertible Subordinated Notes was $173,650,000 as of December 31, 1998.
The fair market values of the convertible subordinated notes are the average of
the NASDAQ's bid and ask amounts as of the respective year end. As of December
31, 1997, the approximate fair value of the 5% Convertible Subordinated Notes is
$15,700,000. Although the interest rate on the 10% Subordinated Notes is fixed,
the carrying value reasonably approximates the fair value at December 31, 1997.

      PPS' shareholders had elected S Corporation taxing status. Thus, PPS'
taxable income was taxed directly to its shareholders. PPS did pay state taxes
in Illinois, Pennsylvania, California and Utah based on its taxable income.
Effective with the merger with Concentra, PPS' taxable income is included in
Concentra's consolidated income tax returns.


(9) STOCKHOLDERS' EQUITY

(a) PREFERRED STOCK

      The Board of Directors is authorized to issue shares of Preferred Stock,
in one or more series, and to fix for each such series the number of shares
thereof and voting powers and such preferences and relative, participating,
optional or other special rights and such qualifications, limitations or
restrictions as are permitted by the Delaware General Corporation Law. The Board
of Directors could authorize the issuance of shares of Preferred Stock with
terms and conditions that could discourage a takeover or other transaction that
holders of some or a majority of shares of Common Stock might believe to be in
their best interests or in which such holders might receive a pre-

                                      F-28
<PAGE>

mium for their shares of stock over the then market price of such shares. As of
the date hereof, no shares of Preferred Stock are outstanding and the Board of
Directors has no present intention to issue any shares of Preferred Stock. See
Note 14 "Subsequent Events" for related disclosure.


(b) STOCKHOLDER RIGHTS PLAN

      Shortly after the 1997 Merger, on September 17, 1997, the Board of
Directors declared, pursuant to a rights agreement (the "Rights Agreement"), a
dividend distribution of one common share purchase right ("Right") for each
outstanding share of Common Stock. Each Right will entitle the registered holder
to purchase from Concentra one thousandth of a share of Series A Junior
Participating Preferred Stock, par value $.01 per share (the "Junior Preferred
Shares"), of Concentra at a price per share to be determined by the Board of
Directors with the advice of its financial advisor about the long-term prospects
for the Company's value (the "Purchase Price"), subject to adjustment. Each
thousandth of a Junior Preferred Share will be economically equivalent to one
share of Concentra Common Stock. The Purchase Price is expected to be
significantly higher than the trading price of the Common Stock. Therefore, the
dividend will have no initial value and no impact on the consolidated financial
statements of the Company. See Note 14, "Subsequent Events" for related
disclosure.


(c) COMMON STOCK

      At December 31, 1998, the Company has reserved approximately 16,839,000
unissued shares of its Common Stock for possible issuance under the Company's
stock option or stock purchase plans and for the issuance upon possible
conversion of the Company's 6% and 4.5% Convertible Subordinated Notes.

      A wholly-owned subsidiary of Health Services has committed to guarantee
$21,408,000 in senior discount notes, plus interest, issued by four development
corporations (Concentra Development Corporation, Concentra Development
Corporation II, Concentra/Sherrer Development Corporation and Concentra/RDA,
Inc.). The stated principal amount of the notes total $42,768,000, which will be
their accreted value at their stated maturity (two to five years after the date
of issuance of each note). These corporations have been organized and
capitalized by a third party to develop occupational healthcare centers in
selected markets in the United States. Health Services also has the right to
acquire the developed centers at fair market value in the future. Health
Services has entered into a management agreement with the development
corporations to manage the healthcare centers' daily operations.

      The Company is party to certain claims and litigation initiated in the
ordinary course of business. The Company is not involved in any legal proceeding
that it believes will result, individually or in the aggregate, in a material
adverse effect upon its financial condition or results of operations. See Note
14, "Subsequent Events" for further claims and litigation disclosures.


(11) EMPLOYEE BENEFIT PLANS

(a) CONCENTRA 401(K) PLAN

      The Company has a defined contribution plan (the "Concentra 401(k) Plan"),
formerly the Managed Care Services 401(k) Plan (the "MCS Concentra 401(k)
Plan"), pursuant to which employees who are at least 21 years of age and who
have completed at least six months of service are eligible to participate.
Participants in the Concentra 401(k) Plan may not contribute more than the
lesser of a specified statutory amount or 15% of his or her pretax total
compensation. The Concentra 401(k) Plan permits, but does not require,
additional matching contributions of up to 50% of participants' pretax
contributions up to a maximum of 6% of compensation by the Company. Employees
are 100% vested in their own contributions while Company contributions vest 20%
per year with employees being fully vested after five years. For 1998, the
Company is making a matching contribution of 50% of participant's pretax
contributions up to 4% of compensation.


(b) HEALTH SERVICES 401(K) PLAN

      Health Services' defined contribution plan (the "HS 401(k) Plan") merged
into the Concentra 401(k) Plan as of July 1, 1998. The HS 401(k) Plan had
similar terms to those of the Concentra 401(k) Plan. There were no matching
contributions under the plan in 1996, 1997 and 1998.


(c) PPS 401(K) PLAN

      PPS' defined contribution plan (the "PPS 401(k) Plan") merged into the
Concentra 401(k) Plan as of August 1, 1998. The PPS 401(k) Plan had similar
terms to those of the Concentra 401(k) Plan. For the years ended December 31,
1996 and 1997 and the seven-month period in 1998, PPS elected to match 25% of
employee contributions up to 7% of gross earnings.

      The Company has expensed $910,000, $1,053,000 and $1,508,000 for the years
ended December 31, 1996, 1997 and 1998, respectively, for matching contributions
to the Concentra 401(k), the MCS 401(k) and the PPS 401(k) Plans.


(12) STOCK PURCHASE PLAN AND STOCK OPTION PLANS

(a) CONCENTRA 1997 EMPLOYEE STOCK PURCHASE PLAN

      The Concentra 1997 Employee Stock Purchase Plan (the "1997 Purchase Plan")
for employees of the Company authorizes the issuance of up to 500,000 shares of
Common Stock pursuant to the exercise of nontransferable options granted to
participating employees. The 1997 Purchase Plan is administered by the
Compensation Committee of the Board of Directors.

      Under the terms of the 1997 Purchase Plan, an employee must authorize the
Company in writing to deduct an amount (not less than 1% nor more than 15% of a
participant's base compensation and in any event not more than


                                      F-30
<PAGE>

      $25,000) from his or her pay during six month periods commencing on
January 1 and July 1 of each year (each a "Purchase Period"). The exercise price
for shares purchased under the 1997 Purchase Plan for each Purchase Period is
the lesser of 85% of the fair market value of the Common Stock on the first or
last business day of the Purchase Period. The fair market value will be the
closing selling price of the Common Stock as quoted.


(B) MANAGED CARE SERVICES AND HEALTH SERVICES EMPLOYEE STOCK PURCHASE PLANS

      Managed Care Services and Health Services each had employee stock purchase
plans under similar terms and conditions as those under the 1997 Purchase Plan.

      The Company issued the following shares of Common Stock under the employee
stock purchase plans for each of the following purchase periods:

                                                                   WEIGHTED

June 30, 1998 ......................        64,587                   $22.10
December 31, 1998 ..................       160,512                   $ 9.08


(c) CONCENTRA 1997 LONG-TERM INCENTIVE PLAN

      Concentra may grant awards with respect to shares under the Company's
Long-term Incentive Plan (the "Concentra Incentive Plan"). The awards under the
Concentra Incentive Plan include: (i) incentive stock options qualified as such
under U.S. federal income tax laws, (ii) stock options that do not qualify as
incentive stock options, (iii) stock appreciation rights ("SARs"), (iv)
restricted stock awards and (v) performance units.

      The number of shares of Common Stock that may be subject to outstanding
awards under the Concentra Incentive Plan at any one time is equal to ten
percent of the total number of outstanding shares of Concentra Common Stock
(treating as outstanding all shares of Common Stock issuable within 60 days upon
exercise of stock options or conversion or exchange of outstanding,
publicly-traded convertible or exchangeable securities of Concentra) minus the
total number of shares of Common Stock subject to outstanding awards under the
Concentra Incentive Plan and any future stock-based plan for employees or
directors of Company. At December 31, 1998, the Company was authorized to award
grants of approximately 5,019,000 shares under the Concentra Incentive Plan. The
number of shares authorized under the Concentra Incentive Plan and the number of
shares subject to an award under the Concentra Incentive Plan will be adjusted
for stock splits, stock dividends, recapitalizations, mergers and other changes
affecting the capital stock of Concentra.

      During 1997, the Company granted restricted stock for 357,000 shares of
Common Stock under the 1997 Incentive Plan which were valued at approximately
$9,903,000 based upon the market value of the shares at the time of issuance. As
of December 31, 1998, 93,000 shares of the restricted stock granted in 1997,
valued at $2,806,000, have been canceled due to forfeiture. During 1998, the
Company granted restricted stock for 48,000 shares of Common Stock under the
1997 Incentive Plan which were valued at $1,413,000 based upon the market value
of the shares at the time of issuance. The restricted stock grants vest 25% per
year beginning January 1, 2002. If the Company's financial performance exceeds
certain established performance goals, however, the vesting of these shares
could accelerate whereby 33-1/3% of the shares could become vested on January 1,
2000 and each year thereafter. For the years ended December 31, 1997 and 1998,
the Company recorded amortization of $562,000 and $805,000, respectively, in
connection with the deferred compensation associated with the restricted stock
grants. During 1997 and 1998, the Company also granted 2,754 and 3,570 shares of
restricted stock to outside directors that vest over one year.


                                      F-31
<PAGE>

      After the 1997 Merger, no additional awards were made under the former CRA
and OccuSystems stock option plans and only that number of shares of Common
Stock issuable upon exercise of awards granted under the former CRA and
OccuSystems stock option plans as of the 1997 Merger were reserved for issuance
by the Company.

      In connection with the 1996 Transaction, PPS canceled all outstanding
stock options and terminated all existing stock option plans. In return for the
cancellation of outstanding options, PPS made a cash payment to the holders of
these options, which resulted in a compensation charge of approximately
$484,000. Upon the cancellation of the options, PPS adopted the 1996 PPS
Replacement Stock Option Plan and the 1996 PPS Incentive Stock Option Plan for
its key employees. The plan provided for the issuance of up to 325,000 shares of
PPS common stock. The exercise price for the incentive stock options could not
be less than the fair market value of the underlying PPS common stock on the
date of grant. After the merger, no additional awards were made under the former
PPS stock option plans and outstanding PPS options were assumed by the Concentra
Incentive Plan totaling approximately 580,000 shares of Concentra common stock.

      A summary of the status for all outstanding options at December 31, 1996,
1997 and 1998 and changes during the years then ended is presented in the table
below:

compensation cost has been recognized related to stock option grants. Had
compensation cost for these plans been determined consistent with Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123"), the Company's net income, pro forma net income,
earnings per share and pro forma earnings per share would have been reduced to

(1)   Pro forma net income and basic and diluted pro forma earnings per share
      for the years ended December 31, 1996 and 1997 have been calculated as if
      PPS had been subject to federal and state income taxes for the entire
      period, based upon an effective tax rate indicative of the statutory rates
      in effect. Prior to its merger with the Company, PPS elected to be taxed
      as an S corporation, and accordingly, was not subject to federal and state
      income taxes in certain jurisdictions.

      Because the method of accounting under SFAS 123 has not been applied to
options granted prior to January 1, 1995, the resulting pro forma compensation
cost may not be representative of that to be expected in future years.
Additionally, the 1996, 1997 and 1998 pro forma amounts include $229,000,
$396,000 and $509,000, respectively, related to purchase discounts offered on
employee stock purchase plans. The fair value of each option granted is
estimated on the date of grant using the Black-Scholes option pricing model with
the following assumptions used for grants in 1996, 1997 and 1998, respectively:

                                            1996       1997       1998

(13) 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.

      Health Services manages occupational healthcare centers at which it
provides support personnel, marketing, information systems and management
services to its affiliated physicians. Health Services owns all the operating
assets of the occupational healthcare centers, including leasehold interests and
medical equipment.

      Specialized Cost Containment services include first report of injury,
utilization management (precertification and concurrent review) retrospective
medical bill review, telephonic case management, preferred provider organization
("PPO") network access, independent medical examinations ("IMEs"), peer reviews
and hospital bill auditing. These services are designed to reduce the cost of
workers' compensation claims, automobile accident injury claims and group health
claims.


                                      F-33
<PAGE>

      Field Case Management provides services involving case managers and nurses
working on a one-on-one basis with injured employees and their various health
care 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 58.7%, 49.3% and 47.7% of total Managed Care Services revenue for the
years ended December 31, 1996, 1997 and 1998, respectively.

      Revenues from individual customers, revenues between business segments and
revenues, operating profit and identifiable assets of foreign operations are not
significant.

      The Company's Statements of Operations on a segment basis for the years
ended December 31, 1996, 1997 and 1998 were as follows:

(14) SUBSEQUENT EVENTS

      On March 2, 1999, Concentra entered into a definitive agreement to merge
(the "Merger") with Yankee Acquisition Corp. ("Yankee"), a corporation formed by
Welsh, Carson, Anderson & Stowe ("WCAS"), a 14.9% stockholder of the Company.
Concentra's Board of Directors unanimously approved the transaction based upon
the recommendation of its special committee of the Board of Directors, which was
formed on October 29, 1998 to evaluate strategic alternatives in response to
several unsolicited expressions of interest regarding the possible acquisition
of some or all of the Company's Common Stock. On March 24, 1999, Concentra
entered into an Amended and Restated Agreement and Plan of Merger with Yankee
(the "Amended Merger Agreement"). Pursuant to the Amended Merger Agreement, WCAS
will acquire approximately 87%, funds managed by Ferrer Freeman Thompson & Co.
("FFT") will acquire approximately 7% and other investors will acquire
approximately 6% of the post-merger shares of common stock of the Company for
$16.50 per share. As a result of the Merger, each outstanding share of Concentra
Common Stock will be converted into the right to receive $16.50 in cash.

      In connection with the Merger, effective March 2, 1999, Concentra amended
its Rights Agreement. The amendment provides, among other things, that Yankee
and its affiliates will not be deemed an Acquiring Person (as such term is
defined in the Rights Agreement) and that the Rights Agreement will expire
immediately prior to the effective time of the Merger.

      The transaction is valued at approximately $1,100,000,000, including the
refinancing of $327,750,000 of the 6% and 4.5% Convertible Subordinated Notes
which contain change in control provisions in the related indentures. The
transaction is structured to be accounted for as a recapitalization and is
expected to be completed in the third quarter of 1999. The transaction is
conditioned upon, among other things, approval of the shareholders of Concentra,
receipt of financing and certain regulatory approvals.

      To finance the acquisition of the Company, WCAS will invest approximately
$369,432,000 in equity financing, including the value of shares and convertible
notes already owned by WCAS, and up to $110,000,000 in subordinated
indebtedness. Additionally, FFT will invest approximately $30,600,000 and other
investors will invest approximately $23,000,000 in equity. WCAS has also
received commitments from various lenders to provide Yankee with $190,000,000 in
senior subordinated notes, a $375,000,000 term loan and a $100,000,000 revolving
credit facility to replace the Company's existing Senior Credit Facility.
Additionally, Concentra would also utilize excess cash on hand at the time of
the merger to help finance the purchase of the Concentra Common Stock.
Simultaneous with the right to receive cash for shares, Yankee would merge with
Concentra with Concentra surviving.

      As of March 26, 1999, Concentra is aware of three lawsuits that have been
filed by alleged stockholders of Concentra relating to the Merger. All three
lawsuits were filed in the Chancery Court for New Castle County, Delaware. Each
of the lawsuits names Concentra, its directors and Yankee as defendants. The
plaintiff in each lawsuit seeks to represent a putative class of all public
holders of Concentra common stock. The lawsuits allege, among


                                      F-35
<PAGE>

other things, that the directors of Concentra breached their fiduciary duties to
Concentra's stockholders by approving the Merger. The lawsuits seek, among other
things, preliminary and permanent injunctive relief prohibiting consummation of
the Merger, unspecified damages, attorneys' fees and other relief. Concentra
expects that these lawsuits will be consolidated into a single action. The
Company intends to contest these lawsuits vigorously.

(1)   Prior to its recapitalization in March of 1994, CRA had elected to be
      taxed as an S corporation. In connection with its recapitalization, CRA
      was required to change from an S to a C corporation. This change resulted
      in CRA recording an incremental tax provision of $3,772,000 in the first
      quarter of 1994. The Company's pro forma net income for 1994 would have
      been $3,466,000 higher had CRA had been subject to federal and state
      income taxes during the entire period based upon an effective tax rate
      indicative of the statutory rate in effect during the period.

(2)   Pro forma net income and basic and diluted pro forma earnings per share,
      where applicable, for the years ended December 31, 1994, 1995, 1996 and
      1997 have been calculated as if PPS had been subject to federal and state
      income taxes for the entire period, based upon an effective tax rate
      indicative of the statutory rates in effect. Prior to its merger with the
      Company, PPS elected to be taxed as an S corporation, and accordingly, was
      not subject to federal and state income taxes in certain jurisdictions.

(1)   The ratio of earnings to fixed charges is computed by dividing the sum of
      net earnings, before deducting provisions for income taxes and fixed
      charges less equity in earnings of unconsolidated subsidiaries, net of
      related distributions, by fixed charges. Fixed charges consist of interest
      on debt, including amortization of debt issuance costs, and one-fourth of
      rent expenses, estimated by management to be the interest component of
      such rentals.

(2)   The ratio of adjusted earnings to fixed charges is computed by dividing
      the sum of net earnings, before deducting nonrecurring charges, provisions
      for income taxes and fixed charges less equity in earnings of
      unconsolidated subsidiaries, net of related distributions, by fixed
      charges. Fixed charges consist of interest on debt, including amortization
      of debt issuance costs, and one-fourth of rent expense, estimated by
      management to be the interest component of such rentals.

      such rentals.

(2)   The ratio of adjusted earnings to fixed charges is computed by dividing
      the sum of net earnings, before deducting nonrecurring charges, provisions
      for income taxes and fixed charges less equity in earnings of
      unconsolidated subsidiaries, net of related distributions, by fixed
      charges. Fixed charges consist of interest on debt, including amortization
      of debt issuance costs, and one-fourth of rent expense, estimated by
      management to be the interest component of such rentals.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

      Section 78.7502(1) of the General Corporation Law of Nevada (the "NGCL")
provides that a Nevada corporation may indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, except an action by or in the right of the corporation, by reason
of the fact that such person is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses, including attorneys' fees,
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding if he or she
acted in good faith and in a manner which he or she reasonably believed to be in
or not opposed to the best interests of the corporation, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful.

      Section 78.7502(2) of the NGCL provides that a Nevada corporation may
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth in subsection (1), against
expenses, including amounts paid in settlement and attorneys' fees actually and
reasonably incurred by such person in connection with the defense or settlement
of such action or suit if he or she acted under the standards set forth in
subsection (1), except that no indemnification may be made for any claim, issue
or matter as to which such person has been adjudged by a court of competent
jurisdiction, after exhaustion of all appeals therefrom, to be liable to the
corporation or for amounts paid in settlement to the corporation, unless and
only to the extent that the court in which such action or suit was brought or
other court of competent jurisdiction determines upon application that in view
of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses as the court deems proper.

      Section 78.7502(3) of the NGCL provides that to the extent a director,
officer, employee or agent of a corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in
subsections (1) and (2), or in defense of any claim, issue or matter therein,
the corporation shall indemnify such person against expenses, including
attorneys' fees, actually and reasonably incurred by him or her in connection
with the defense.

      Section 78.751(1) of the NGCL provides that any discretionary
indemnification under Section 78.7502, unless ordered by a court or advanced
pursuant to subsection 2 of Section 78.751, may be made by the corporation only
as authorized in the specific case upon determination that indemnification of
such director, officer, employee or agent is proper in the circumstances. The
determination must be made (a) by the stockholders; (b) by the board of
directors by majority vote of quorum consisting of directors who were not
parties to the action, suit or proceeding; (c) if a majority vote of a quorum
consisting of directors who were not parties to the action, suit or proceeding
so orders, by independent legal counsel in a written opinion; or (d) if a quorum
consisting of directors who were not parties to the action, suit or proceeding
cannot be obtained, by independent legal counsel in a written opinion.

      Section 78.751(2) of the NGCL provides that the articles of incorporation,
bylaws or an agreement made by the corporation may provide that the expenses of
officers and directors incurred in defending a civil or criminal action, suit or
proceeding must be paid by the corporation as they are incurred and in advance
of the final disposition of the action, suit or proceeding, upon receipt of an
undertaking by or on behalf of the director or officer to repay the amount if it
is ultimately determined by a court of competent jurisdiction that he or she is
not entitled to be indemnified by the corporation. Such provision does not
affect any rights to advancement of expenses to which corporate personnel other
than directors or officers may be entitled under any contract or otherwise by
law.

      Section 78.752 of the NGCL provides that a Nevada corporation may purchase
and maintain insurance or make other financial arrangements on behalf of any
person who acted in any of the capacities set forth above for any lia-


                                      II-1

bility asserted against such person for any liability asserted against him or
her and liability and expenses incurred by him or her in any such capacity or
arising out of his or her status as such, whether or not the corporation has the
authority to indemnify him or her against such liabilities and expenses.

      The By-Laws of Concentra Operating Corporation ("COC") provide that every
person serving as its directors or officers and every such director or officer
serving at the request of COC as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise shall
be indemnified by COC in accordance with and to the fullest extent permitted by
law for the defense of, in connection with, any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative.

      Concentra Managed Care, Inc. ("CMC"), the parent of COC, has entered into
indemnity agreements with the directors and officers of CMC and its wholly
owned, direct and indirect, subsidiaries, including the Registrants. Pursuant to
such agreements, CMC will, to the extent permitted by applicable law, indemnify
such persons against all expenses, judgments, fines and penalties incurred in

reason of the fact that they were directors or officers of such Registrant or
assumed certain responsibilities at the direction of such Registrant. In
addition, CMC has purchased and maintains insurance to protect persons entitled
to indemnification pursuant to its by-laws or the applicable law against
expenses, judgments, fines and amounts paid in settlement, to the fullest extent
permitted by the Delaware General Corporation Law. Such insurance covers the
directors and officers of the Registrants.

ITEM 22. UNDERTAKINGS

      (a)  The undersigned registrant hereby undertakes:

           (1)  To file, during any period in which offers or sales are being
                made, a post-effective amendment to this registration statement:

                (i)  To include any prospectus required by Section 10(a)(3) of
                     the Securities Act;

                (ii) To reflect in the prospectus any facts or events arising
                     after the effective date of the registration statement (or
                     the most recent post-effective amendment thereof) which,
                     individually or in the aggregate, represent a fundamental
                     change in the information set forth in the registration
                     statement;

                (iii)To include any material information with respect to the
                     plan of distribution not previously disclosed in the
                     registration statement or any material change in such
                     information in the registration statement;

           (2)  That, for the purpose of determining any liability under the
                Securities Act, each such post-effective amendment shall be
                deemed to be a new registration statement relating to the
                securities offered therein, and the offering of such securities
                at the time shall be deemed to be initial bona fide offering
                thereof.

           (3)  To remove from registration by means of a post-effective
                amendment any of the securities being registered which remain
                unsold at the termination of the offering.

      (b)  Insofar as indemnification for liabilities arising under the
           Securities Act may be permitted to directors, officers and
           controlling persons of the registrant pursuant to the foregoing
           provisions, or otherwise, the registrant has been advised that in
           the opinion of the Securities and Exchange Commission such
           indemnification is against public policy as expressed in the Act and
           is, therefore, unenforceable. In the event that a claim for
           indemnification against such liabilities (other than the payment by
           the registrant of expenses incurred or paid by a director, officer
           or controlling person of the registrant in the successful defense of
           any action, suit or proceeding) is asserted by such director,
           officer or controlling person in connection with the securities
           being registered, the registrant will, unless in the opinion of its
           counsel the matter has been settled by controlling precedent, submit
           to a court of appropriate jurisdiction the question whether such
           indemnification by it is against public policy as expressed in the
           Act and will be governed by the final adjudication of such issue.

      (c)  The undersigned registrant hereby undertakes that, for purposes of
           determining any liability under the Securities Act, each filing of
           the registrant's annual report pursuant to Section 13(a) or Section
           15(d) of the Exchange Act (and, where applicable, each filing of an
           employee benefit plan's annual report pursuant to Section 15(d) of
           the Exchange Act) that is incorporated by reference in the
           registration statement shall be deemed to be a new registration
           statement relating to the securities offered therein, and the
           offering of such securities at that time shall be deemed to be the
           initial bona fide offering thereof.

      (d)  The undersigned registrant hereby undertakes to respond to requests
           for information that is incorporated by reference into the prospectus
           pursuant to Items 4, 10(b), 11 or 13 of this form, within one
           business day of receipt of such request, and to send the incorporated
           documents by first class mail or other equally prompt means. This
           includes information contained in documents filed subsequent to the
           effective date of the registration statement through the date of
           responding to the request.

      (e)  The undersigned registrant hereby undertakes to supply by means of a
           post-effective amendment all information concerning a transaction,
           and the company being acquired involved therein, that was not the
           subject of and included in the registration statement when it became
           effective.

         SECTION 1. PLACE OF  MEETINGS.  All meetings of  stockholders  shall be
held at such place or places, within or without the State of Nevada, as may from
time to time be fixed by the Board of Directors, or as shall be specified in the
respective notices, or waivers of notice, thereof.

         SECTION 2. ANNUAL MEETING.  The annual meeting of stockholders  for the
election of Directors and the  transaction  of other  business  shall be held on
such date and at such place as may be designated  by the Board of Directors.  At

to vote shall elect a Board of  Directors  and may  transact  such other  proper
business as may come before the meeting.

         SECTION 3. SPECIAL MEETINGS. A special meeting of the stockholders,  or
of any class  thereof  entitled  to vote,  for any purpose or  purposes,  may be
called at any time by the Chairman of the Board,  if any, or the President or by

Such written  request shall state the purpose or purposes for which such meeting
is to be called.

written  notice of each  meeting of  stockholders,  whether  annual or  special,

to each  stockholder  of record  entitled to vote thereat by delivering a notice
thereof  to him  personally  or by  mailing  such  notice in a  postage  prepaid
envelope  directed  to him at his  address as it  appears on the  records of the
Corporation,  unless he shall have filed with the Secretary of the Corporation a
written request that notices intended for him be directed to another address, in
which case such notice  shall be directed  to him at the address  designated  in
such request.  Notice shall not be required to be given to any  stockholder  who
shall waive such notice in writing,  whether prior to or after such meeting,  or
who shall attend such meeting in person or by proxy  unless such  attendance  is
for the express purpose of objecting,  at the beginning of such meeting,  to the
transactions  of any  business  because  the meeting is not  lawfully  called or
convened.  Every notice of a special  meeting of the  stockholders,  besides the
time and place of the  meeting,  shall  state  briefly  the  objects or purposes
thereof.

         SECTION 5. LIST OF STOCKHOLDERS.  It shall be the duty of the Secretary
or other officer of the Corporation who shall have charge of the stock ledger to
prepare and make, at least ten days before every meeting of the stockholders,  a
complete  list  of the  stockholders  entitled  to  vote  thereat,  arranged  in
alphabetical  order,  and showing the address of each stockholder and the number
of shares  registered in his name. Such list shall be open to the examination of
any  stockholder,  for any  purpose  germane  to the  meeting,  during  ordinary
business hours,  for a period of at least ten days prior to the meeting,  either
at a place within the city where the meeting is to be held, which place shall be
specified in the notice of the meeting,  or, if not so  specified,  at the place
where the meeting is to be held. The list shall be kept and produced at the time
and place of the  meeting  during  the whole  time  thereof  and  subject to the
inspection  of any  stockholder  who may be present.  The  original or duplicate
ledger  shall be the only  evidence as to who are the  stockholders  entitled to
examine  such  list or the books of the  Corporation  or to vote in person or by
proxy at such meeting.

         SECTION 6. QUORUM. At each meeting of the stockholders,  the holders of
record of a  majority  of the issued and  outstanding  stock of the  Corporation
entitled  to vote  at  such  meeting,  present  in  person  or by  proxy,  shall

provided by law, the  Certificate  of  Incorporation  or these  By-laws. In

                                       3

the absence of a quorum, any officer entitled to preside at, or act as Secretary
of, such  meeting  shall have the power to adjourn the meeting from time to time
until a quorum shall be constituted.

         SECTION 7. VOTING.  Every stockholder of record who is entitled to vote
shall at every  meeting of the  stockholders  be  entitled  to one vote for each
share of stock held by him on the record date; EXCEPT,  HOWEVER,  that shares of
its own stock  belonging  to the  Corporation  or to another  corporation,  if a
majority of the shares  entitled to vote in the  election of  directors  of such
other corporation is held by the Corporation,  shall neither be entitled to vote
nor counted for quorum  purposes.  Nothing in this Section shall be construed as
limiting  the right of the  Corporation  to vote its own  stock  held by it in a
fiduciary capacity. At all meetings of the stockholders, a quorum being present,
all matters shall be decided by majority vote of the shares of stock entitled to
vote held by  stockholders  present in person or by proxy,  except as  otherwise
required  by law or the  Certificate  of  Incorporation.  Unless  demanded  by a
stockholder of the  Corporation  present in person or by proxy at any meeting of
the  stockholders and entitled to vote thereat or so directed by the chairman of
the meeting or required by law, the vote thereat on any question  need not be by
written ballot. On a vote by written ballot,  each ballot shall be signed by the
stockholder  voting,  or in his name by his proxy,  if there be such proxy,  and
shall  state the number of shares  voted by him and the number of votes to which
each share is entitled.

         SECTION 8. PROXIES.  Each stockholder  entitled to vote at a meeting of
stockholders  or to express  consent to  corporate  action in writing  without a
meeting may authorize another person or persons to act for him by proxy. A proxy
acting for any  stockholder  shall be duly appointed by an instrument in writing
subscribed by such stockholder.  No proxy shall be valid after the expiration of
three years from the date thereof unless the proxy provides for a longer period.

         SECTION 9. ACTION WITHOUT A MEETING. Any action required to be taken at
any annual or special  meeting of  stockholders or any action which may be taken
at any annual or special meeting of stockholders may be taken without a meeting,
without prior notice and without a vote,  if a consent in writing  setting forth
the action so taken shall be signed by the holders of  outstanding  stock having
not less than the minimum  number of votes that would be  necessary to authorize
or take such action at a meeting at which all shares  entitled  to vote  thereon
were  present and voted.  Prompt  notice of the taking of the  corporate  action
without a meeting by less than unanimous written consent shall be given to those
stockholders who have not consented in writing.


                                   ARTICLE III

are elected and qualify,  or until they sooner die,  resign or are  removed.  At
each annual meeting of stockholders,  at which a quorum is present,  the persons
receiving a plurality of the votes cast shall be the  Directors.  Acceptance  of
the office of Director may be expressed orally or in writing,  and attendance at
the organization meeting shall constitute such acceptance.

         SECTION 3.  NUMBER.  The number of  Directors  shall be such  number as
shall be  determined  from time to time by the Board of Directors  and initially
shall be two.

         SECTION 4. QUORUM AND MANNER OF ACTING.  Unless  otherwise  provided by
law, the  presence of 50% of the whole Board of Directors  shall be necessary to
constitute a quorum for the transaction of business. In the absence of a quorum,
a majority of the  Directors  present may adjourn the meeting  from time to time
until a quorum  shall be present.  Notice of any  adjourned  meeting need not be
given. At all meetings of Directors,  a quorum being present,  all matters shall
be  decided by the  affirmative  vote of a majority  of the  Directors  present,
except  as  otherwise  required  by law.  The  Board of  Directors  may hold its
meetings  at such place or places  within or without  the State of Nevada as the
Board of Directors  may from time to time  determine or as shall be specified in
the respective notices, or waivers of notice, thereof.

         SECTION 5. ORGANIZATION MEETING.  Immediately after each annual meeting
of stockholders  for the election of Directors the Board of Directors shall meet
at  the  place  of the  annual  meeting  of  stockholders  for  the  purpose  of
organization,  the election of officers and the  transaction of other  business.
Notice of such meeting  need not be given.  If such meeting is held at any other
time or place, notice thereof must be given as hereinafter  provided for special
meetings of the Board of Directors,  subject to the execution of a waiver of the
notice  thereof  signed by, or the  attendance at such meeting of, all Directors
who may not have received such notice.

         SECTION 6. REGULAR MEETINGS. Regular meetings of the Board of Directors
may be held at such place,  within or without the State of Nevada, as shall from
time to time be determined by the Board of Directors.  After there has been such
determination,  and notice  thereof  has been once  given to each  member of the
Board of  Directors  as  hereinafter  provided  for  special  meetings,  regular
meetings may be held without further notice being given.

         SECTION 7. SPECIAL MEETINGS;  NOTICE.  Special meetings of the Board of
Directors  shall be held whenever  called by the Chairman of the Board,  if any,
the  President  or by a majority of the  Directors.  Notice of each such meeting
shall be mailed to each  Director,  addressed  to him at his  residence or usual
place of business, at least five days before the date on which the meeting is to
be  held,  or shall be sent to him at such  place by telex or  facsimile,  or be
delivered  personally or by telephone,  not later than the day before the day on
which such  meeting is to be held.  Each such  notice  shall  state the time and
place of the meeting and, as may be required,  the

                                       5
<PAGE>

purposes  thereof.  Notice of any meeting of the Board of Directors  need not be
given to any Director if he shall sign a written waiver thereof either before or
after the time stated therein for such meeting, or if he shall be present at the
meeting. Unless limited by law, the Certificate of Incorporation,  these By-laws
or the terms of the notice  thereof,  any and all business may be  transacted at
any meeting  without  the notice  thereof  having  specifically  identified  the
matters to be acted upon.

         SECTION 8.  REMOVAL OF  DIRECTORS.  Any Director or the entire Board of
Directors may be removed,  with or without cause,  at any time, by action of the
holders of record of the  majority  of the issued and  outstanding  stock of the
Corporation  (a)  present  in person or by proxy at a meeting of holders of such
stock and  entitled to vote thereon or (b) by a consent in writing in the manner
contemplated  in Section 9 of Article  II, and the vacancy or  vacancies  in the
Board of Directors  caused by any such removal may be filled by action of such a
majority at such meeting or at any subsequent meeting or by consent.

         SECTION 9. RESIGNATIONS.  Any Director of the Corporation may resign at
any time by giving  written  notice to the  Chairman of the Board,  if any,  the
President,  the  Vice  President  or  the  Secretary  of  the  Corporation.  The
resignation  of any Director shall take effect upon receipt of notice thereof or
at such later time as shall be specified in such notice;  and, unless  otherwise
specified therein,  the acceptance of such resignation shall not be necessary to
make it effective.

         SECTION 10.  VACANCIES.  Any newly created  directorships and vacancies
occurring   in  the  Board  by  reason   of  death,   resignation,   retirement,
disqualification or removal,  with or without cause, may be filled by the action
of the holders of record of the majority of the issued and outstanding  stock of
the  Corporation  (a)  present  in person or by proxy at a meeting of holders of
such stock and  entitled  to vote  thereon or (b) by a consent in writing in the
manner contemplated in Section 9 of Article II. The Director so chosen,  whether
selected to fill a vacancy or elected to a new  directorship,  shall hold office
until the next meeting of  stockholders at which the election of Directors is in
the regular  order of  business,  and until his  successor  has been elected and
qualifies, or until he sooner dies, resigns or is removed.

         SECTION 11.  COMPENSATION OF DIRECTORS.  Directors,  as such, shall not
receive any stated salary for their services, but, by resolution of the Board, a
specific sum fixed by the Board plus  expenses may be allowed for  attendance at
each regular or special meeting of the Board;  PROVIDED,  HOWEVER,  that nothing
herein  contained  shall be construed to preclude any Director  from serving the
Corporation  or any  parent  or  subsidiary  corporation  thereof  in any  other
capacity and receiving compensation therefor.

         SECTION 12. ACTION WITHOUT A MEETING.  Any action required or permitted
to be taken at any  meeting  of the Board of  Directors  may be taken  without a
meeting if a written consent thereto is signed by all members of the Board,  and
such written consent is filed with the minutes or proceedings of the Board.

of Directors  may  participate  in a meeting of the Board by means of conference
telephone  or similar  communications  equipment  by means of which all  persons
participating in the meeting can hear each other, and such  participation  shall
constitute presence in person at such meeting.

         SECTION  1. RIGHT OF  INDEMNIFICATION.  Every  person now or  hereafter
serving as a Director or officer of the  Corporation  and every such Director or
officer  serving  at the  request of the  Corporation  as a  director,  officer,
employee or agent of another corporation,  partnership,  joint venture, trust or
other enterprise, shall be indemnified by the Corporation in accordance with and
to the fullest  extent  permitted  by law for the  defense of, or in  connection

final disposition of such action,  suit or proceeding as authorized by the Board

                                   ARTICLE VI

                            SHARES AND THEIR TRANSFER

         SECTION 1. CERTIFICATE FOR STOCK.  Every stockholder of the Corporation
shall be entitled to a certificate  or  certificates,  to be in such form as the
Board of  Directors  shall  prescribe,  certifying  the  number of shares of the
capital stock of the  Corporation  owned by him. No certificate  shall be issued
for partly paid shares.

         SECTION 2. STOCK CERTIFICATE SIGNATURE. The certificates for such stock
shall be numbered in the order in which they shall be issued and shall be signed
by the Chairman of the Board, if any, or the President or any Vice President and

                                       9
<PAGE>

(2) by a registrar other than the Corporation or its employee, the signatures of
such officers of the Corporation  may be facsimiles.  In case any officer of the
Corporation who has signed,  or whose facsimile  signature has been placed upon,
any  such  certificate  shall  have  ceased  to  be  such  officer  before  such
certificate is issued,  it may be issued by the Corporation with the same effect
as if he were such officer at the date of issue.

         SECTION 3. STOCK LEDGER.  A record shall be kept by the Secretary or by
any other officer, employee or agent designated by the Board of Directors of the
name  of  each  person,  firm  or  corporation  holding  capital  stock  of  the

Corporation for exchange or  registration of transfer shall be canceled,  and no
new  certificate  or  certificates  shall be issued in exchange for any existing

subject to Section 7 of this  Article VI, in cases  provided  for by  applicable
law.

         SECTION  5.  REGISTRATIONS  OF  TRANSFERS  OF STOCK.  Registrations  of
transfers of shares of the capital stock of the Corporation shall be made on the
books of the Corporation by the registered  holder  thereof,  or by his attorney
thereunto  authorized  by power of  attorney  duly  executed  and filed with the
Secretary  of the  Corporation  or with a  transfer  clerk or a  transfer  agent
appointed as in Section 6 of this  Article VI provided,  and on surrender of the
certificate or certificates for such shares properly endorsed and the payment of

of dividends in violation of Section 78.300 of the Nevada Revised Statutes. Any
repeal or modification of this Article VI by the stockholders of the Corporation
shall be prospective only, and shall not adversely affect any limitation on the

omissions prior to such repeal or modification.

                                   ARTICLE VII

representative is or was a director, officer, agent or employee of another
corporation, partnership, joint venture, trust or other enterprise, shall be
indemnified and held harmless to the fullest extent legally permissible under
the laws of the State of Nevada, from time to time existing, against all
expenses, liability and loss (including attorneys' fees, judgments, fines and
amounts paid or to be paid in settlement) reasonably incurred or suffered by
such person in connection therewith. Such right of indemnification shall be a
contract right which may be enforced in any manner desired by such person. Such
right of indemnification shall not be exclusive of any other right which such
director, officer or representative may have or hereafter acquire, and, without
limiting the generality of such statement, such persons shall be entitled to

stockholders, provision of law, or otherwise, as well as their rights under this
Article VII.

     SECTION 7.2 EXPENSES ADVANCED. Expenses of directors and officers incurred
in defending a civil or criminal action, suit or proceeding by reason of any act
or omission of such director or officer acting as a director or officer shall be
paid by the Corporation as such expenses are incurred and in advance of the

serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against such person and incurred in
any such capacity or arising out of such status, to the fullest extent permitted
by the laws of the State of Nevada, whether or not the Corporation would have
the power to indemnify such person against such liability and expenses.

     SECTION 7.4 SURVIVAL. The indemnification and advancement of expenses
provided in this Article VII shall continue for a person who has ceased to be a
director. officer, employee or agent, and inures to the benefit of the heirs,

President or by order of the Board of Directors and shall be called by the
Secretary upon the written request of stockholders holding of record at least
50% of the outstanding shares of stock of the Corporation entitled to vote at
such meeting. Such written request shall state the purpose or purposes for which

               SECTION 4. NOTICE OF MEETINGS. Except as otherwise provided by
law, written notice of each meeting of stockholders, whether annual or special,

thereof to him personally or by mailing such notice in a postage prepaid
envelope directed to him at his address as it appears on the records of the
Corporation, unless he shall have filed with the Secretary of the Corporation a
written request that notices intended for him be directed to another address, in
which case such notice shall be directed to him at the address designated in
such request. Notice shall not be required to be given to any stockholder who
shall waive such notice in writing, whether prior to or after such meeting, or
who shall attend such meeting in person or by proxy unless such attendance is
for the express purpose of objecting, at the beginning of such meeting, to the
transactions of any business because the meeting is not lawfully called or
convened. Every notice of a special meeting of the stockholders, besides the
time and place of the meeting, shall state briefly the objects or purposes
thereof.

               SECTION 5. LIST OF STOCKHOLDERS. It shall be the duty of the
Secretary or other officer of the Corporation who shall have charge of the stock
ledger to prepare and make, at least ten days before every meeting of the
stockholders, a complete list of the stockholders entitled to vote thereat,

examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place within the city where the meeting is to be held, which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place where the meeting is to be held. The list shall be kept and produced at
the time and place of the meeting during the whole time thereof and subject to
the inspection of any stockholder who may be present. The original or duplicate
ledger shall be the only evidence as to who are the stockholders entitled to
examine such list or the books of the Corporation or to vote in person or by
proxy at such meeting.

otherwise provided by law, the Certificate of Incorporation or these By-laws. In
the absence of a quorum, any officer entitled to preside at, or act as Secretary
of, such meeting shall have the power to adjourn the meeting from time to time
until a quorum shall be constituted.

               SECTION 7. VOTING. Every stockholder of record who is entitled to
vote shall at every meeting of the stockholders be entitled to one vote for each
share of stock held by him on the record date; EXCEPT, HOWEVER, that shares of
its own stock belonging to the Corporation or to another corporation, if a
majority of the shares entitled to vote in the election of directors of such
other corporation is held by the Corporation, shall neither be entitled to vote
nor counted for quorum purposes. Nothing in this Section shall be construed as
limiting the right of the Corporation to vote its own stock held by it in a
fiduciary capacity. At all meetings of the stockholders, a quorum being present,
all matters shall be decided by majority vote of the shares of stock entitled to
vote held by stockholders present in person or by proxy, except as otherwise
required by law or the Certificate of Incorporation. Unless demanded by a
stockholder of the Corporation present in person or by proxy at any meeting of
the stockholders and entitled to vote thereat or so directed by the chairman of
the meeting or required by law, the vote thereat on any question need not be by
written ballot. On a vote by written ballot, each ballot shall be signed by the
stockholder voting, or in his name by his proxy, if there be such proxy, and
shall state the number of shares voted by him and the number of votes to which
each share is entitled.

               SECTION 8. PROXIES. Each stockholder entitled to vote at a
meeting of stockholders or to express consent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy. A proxy acting for any stockholder shall be duly appointed by an
instrument in writing subscribed by such stockholder. No proxy shall be valid
after the expiration of three years from the date thereof unless the proxy
provides for a longer period.

               SECTION 9. ACTION WITHOUT A MEETING. Any action required to be
taken at any annual or special meeting of stockholders or any action which may
be taken at any annual or special meeting of stockholders may be taken without a
meeting, without prior notice and without a vote, if a consent in writing
setting forth the action so taken shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted. Prompt notice of the taking of the
corporate action without a meeting by less than unanimous written consent shall
be given to those stockholders who have not consented in writing.


                                   ARTICLE III

removed. At each annual meeting of stockholders, at which a quorum is

                                       4
<PAGE>

present, the persons receiving a plurality of the votes cast shall be the
Directors. Acceptance of the office of Director may be expressed orally or in
writing, and attendance at the organization meeting shall constitute such
acceptance.

               SECTION 3.  NUMBER. The number of Directors shall be such number
as shall be determined from time to time by the Board of Directors and initially
shall be two.

               SECTION 4. QUORUM AND MANNER OF ACTING. Unless otherwise provided
by law, the presence of 50% of the whole Board of Directors shall be necessary
to constitute a quorum for the transaction of business. In the absence of a
quorum, a majority of the Directors present may adjourn the meeting from time to
time until a quorum shall be present. Notice of any adjourned meeting need not
be given. At all meetings of Directors, a quorum being present, all matters
shall be decided by the affirmative vote of a majority of the Directors present,
except as otherwise required by law. The Board of Directors may hold its
meetings at such place or places within or without the State of Nevada as the
Board of Directors may from time to time determine or as shall be specified in
the respective notices, or waivers of notice, thereof.

               SECTION 5. ORGANIZATION MEETING. Immediately after each annual
meeting of stockholders for the election of Directors the Board of Directors
shall meet at the place of the annual meeting of stockholders for the purpose of
organization, the election of officers and the transaction of other business.
Notice of such meeting need not be given. If such meeting is held at any other
time or place, notice thereof must be given as hereinafter provided for special
meetings of the Board of Directors, subject to the execution of a waiver of the
notice thereof signed by, or the attendance at such meeting of, all Directors
who may not have received such notice.

               SECTION 6. REGULAR MEETINGS. Regular meetings of the Board of
Directors may be held at such place, within or without the State of Nevada, as
shall from time to time be determined by the Board of Directors. After there has
been such determination, and notice thereof has been once given to each member
of the Board of Directors as hereinafter provided for special meetings, regular
meetings may be held without further notice being given.

               SECTION 7. SPECIAL MEETINGS; NOTICE. Special meetings of the
Board of Directors shall be held whenever called by the Chairman of the Board,
if any, the President or by a majority of the Directors. Notice of each such
meeting shall be mailed to each Director, addressed to him at his residence or
usual place of business, at least five days before the date on which the meeting
is to be held, or shall be sent to him at such place by telex or facsimile, or
be delivered personally or by telephone, not later than the day before the day
on which such meeting is to be held. Each such notice shall state the time and
place of the meeting and, as may be required, the purposes thereof. Notice of
any meeting of the Board of Directors need not be given to any Director if he
shall sign a written waiver thereof either before or after the time stated
therein for such meeting, or if he shall be present at the meeting. Unless
limited by law, the Certificate of Incorporation, these By-laws or the terms of
the notice thereof, any and all business may be transacted at any meeting

               SECTION 1. CERTIFICATE FOR STOCK. Every stockholder of the
Corporation shall be entitled to a certificate or certificates, to be in such

Corporation for transfer, both the transferor and the transferee request the
Corporation to do so.

               SECTION 6. REGULATIONS. The Board of Directors may make such

other lawful action, the Board of Directors may fix, in advance, a date as a
record date for any such determination of stockholders. Such record date shall

for the express purpose of objecting, at the beginning of such meeting, to the
transactions of any business because the meeting is not lawfully called or
convened. Every notice of a special meeting of the stockholders, besides the
time and place of the meeting, shall state briefly the objects or purposes
thereof.

          SECTION 5. LIST OF STOCKHOLDERS. It shall be the duty of the Secretary
or other officer of the Corporation who shall have charge of the stock ledger to
prepare and make, at least ten days before every meeting of the stockholders, a
complete list of the stockholders entitled to vote thereat, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in his name. Such list shall be open to the examination of
any stockholder, for any purpose germane to the meeting, during ordinary
business hours, for a period of at least ten days prior to the meeting, either
at a place within the city where the meeting is to be held, which place shall be
specified in the notice of the meeting, or, if not so specified, at the place
where the meeting is to be held. The list shall be kept and produced at the time
and place of the meeting during the whole time thereof and subject to the
inspection of any stockholder who may be present. The original or duplicate
ledger shall be the only evidence as to who are the stockholders entitled to
examine such list or the books of the Corporation or to vote in person or by
proxy at such meeting.

          SECTION 6. QUORUM. At each meeting of the stockholders, the holders of
record of a majority of the issued and outstanding stock of the Corporation
entitled to vote at such meeting, present in person or by proxy, shall
constitute a quorum for the transaction of business, except where otherwise
provided by law, the Certificate of Incorporation or these By-laws. In the
absence of a quorum, any officer entitled to preside at, or act as Secretary of,
such meeting

                                       3

shall be constituted.

          SECTION 7. VOTING. Every stockholder of record who is entitled to vote
shall at every meeting of the stockholders be entitled to one vote for each
share of stock held by him on the record date; EXCEPT, HOWEVER, that shares of
its own stock belonging to the Corporation or to another corporation, if a
majority of the shares entitled to vote in the election of directors of such
other corporation is held by the Corporation, shall neither be entitled to vote
nor counted for quorum purposes. Nothing in this Section shall be construed as
limiting the right of the Corporation to vote its own stock held by it in a
fiduciary capacity. At all meetings of the stockholders, a quorum being present,
all matters shall be decided by majority vote of the shares of stock entitled to
vote held by stockholders present in person or by proxy, except as otherwise
required by law or the Certificate of Incorporation. Unless demanded by a
stockholder of the Corporation present in person or by proxy at any meeting of
the stockholders and entitled to vote thereat or so directed by the chairman of
the meeting or required by law, the vote thereat on any question need not be by
written ballot. On a vote by written ballot, each ballot shall be signed by the
stockholder voting, or in his name by his proxy, if there be such proxy, and
shall state the number of shares voted by him and the number of votes to which
each share is entitled.

          SECTION 8. PROXIES. Each stockholder entitled to vote at a meeting of
stockholders or to express consent to corporate action in writing without a
meeting may authorize another person or persons to act for him by proxy. A proxy
acting for any stockholder shall be duly appointed by an instrument in writing
subscribed by such stockholder. No proxy shall be valid after the expiration of
three years from the date thereof unless the proxy provides for a longer period.

          SECTION 9. ACTION WITHOUT A MEETING. Any action required to be taken
at any annual or special meeting of stockholders or any action which may be
taken at any annual or special meeting of stockholders may be taken without a
meeting, without prior notice and without a vote, if a consent in writing
setting forth the action so taken shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted. Prompt notice of the taking of the
corporate action without a meeting by less than unanimous written consent shall
be given to those stockholders who have not consented in writing.

the regular order of business, and until his successor has been elected and
qualifies, or until he sooner dies, resigns or is removed.

                                   ARTICLE II

                  SECTION 1. PLACE OF MEETINGS. All meetings of stockholders
shall be held at such place or places, within or without the State of Delaware,

                  SECTION 3. SPECIAL MEETINGS. A special meeting of the

purposes, may be called at any time by the Chairman of the Board, if any, or the
President or by order of the Board of Directors and shall be called by the
Secretary upon the written request of stockholders holding of record at least
50% of the outstanding shares of stock of the Corporation entitled to vote at
such meeting. Such written request shall state the purpose or purposes for which
such meeting is to be called.

                  SECTION 4. NOTICE OF MEETINGS. Except as otherwise provided by
law, written notice of each meeting of stockholders, whether annual or special,
stating the place, date and hour of the meeting shall be given not less than ten
days or more than sixty days before the date on which the meeting is to be held
to each stockholder of record entitled to vote thereat by delivering a notice
thereof to him personally or by mailing such notice in a postage prepaid
envelope directed to him at his address as it appears on the records of the
Corporation, unless he shall have filed with the Secretary of the Corporation a
written request that notices intended for him be directed to another address, in
which case such notice shall be directed to him at the address designated in
such request. Notice shall not be required to be given to any stockholder who
shall waive such notice in writing, whether prior to or after such meeting, or
who shall attend such meeting in person or by proxy unless such attendance is
for the express purpose of objecting, at the beginning of such meeting, to the
transactions of any business because the meeting is not lawfully called or
convened. Every notice of a special meeting of the stockholders, besides the
time and place of the meeting, shall state briefly the objects or purposes
thereof.

                  SECTION 5. LIST OF STOCKHOLDERS. It shall be the duty of the
Secretary or other officer of the Corporation who shall have charge of the stock
ledger to prepare and make, at least ten days before every meeting of the
stockholders, a complete list of the stockholders entitled to vote thereat,

the number of shares registered in his name. Such list shall be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place within the city where the meeting is to be held, which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place where the meeting is to be held. The list shall be kept and produced at
the time and place of the meeting during the whole time thereof and subject to
the inspection of any stockholder who may be present. The original or duplicate
ledger shall be the only evidence as to who are the stockholders entitled to
examine such list or the books of the Corporation or to vote in person or by

the absence of a quorum, any officer entitled to preside at, or act as Secretary
of, such meeting

                                       3

                  SECTION 7. VOTING. Every stockholder of record who is entitled
to vote shall at every meeting of the stockholders be entitled to one vote for
each share of stock held by him on the record date; EXCEPT, HOWEVER, that shares
of its own stock belonging to the Corporation or to another corporation, if a
majority of the shares entitled to vote in the election of directors of such
other corporation is held by the Corporation, shall neither be entitled to vote
nor counted for quorum purposes. Nothing in this Section shall be construed as
limiting the right of the Corporation to vote its own stock held by it in a
fiduciary capacity. At all meetings of the stockholders, a quorum being present,
all matters shall be decided by majority vote of the shares of stock entitled to
vote held by stockholders present in person or by proxy, except as otherwise
required by law or the Certificate of Incorporation. Unless demanded by a
stockholder of the Corporation present in person or by proxy at any meeting of
the stockholders and entitled to vote thereat or so directed by the chairman of
the meeting or required by law, the vote thereat on any question need not be by
written ballot. On a vote by written ballot, each ballot shall be signed by the
stockholder voting, or in his name by his proxy, if there be such proxy, and
shall state the number of shares voted by him and the number of votes to which
each share is entitled.

                  SECTION 8. PROXIES. Each stockholder entitled to vote at a
meeting of stockholders or to express consent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy. A proxy acting for any stockholder shall be duly appointed by an
instrument in writing subscribed by such stockholder. No proxy shall be valid
after the expiration of three years from the date thereof unless the proxy
provides for a longer period.

                  SECTION 9. ACTION WITHOUT A MEETING. Any action required to be
taken at any annual or special meeting of stockholders or any action which may
be taken at any annual or special meeting of stockholders may be taken without a
meeting, without prior notice and without a vote, if a consent in writing
setting forth the action so taken shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted. Prompt notice of the taking of the
corporate action without a meeting by less than unanimous written consent shall
be given to those stockholders who have not consented in writing.

removed. At each annual meeting of stockholders, at which a quorum is present,
the persons receiving a plurality of the votes cast shall be the Directors.

number as shall be determined from time to time by the Board of Directors and
initially shall be two.

                  SECTION 4. QUORUM AND MANNER OF ACTING. Unless otherwise
provided by law, the presence of 50% of the whole Board of Directors shall be
necessary to constitute a quorum for the transaction of business. In the absence
of a quorum, a majority of the Directors present may adjourn the meeting from
time to time until a quorum shall be present. Notice of any adjourned meeting
need not be given. At all meetings of Directors, a quorum being present, all
matters shall be decided by the affirmative vote of a majority of the Directors
present, except as otherwise required by law. The Board of Directors may hold
its meetings at such place or places within or without the State of Delaware as
the Board of Directors may from time to time determine or as shall be specified

organization, the election of officers and the transaction of other business.
Notice of such meeting need not be given. If such meeting is held at any other
time or place, notice thereof must be given as hereinafter provided for special
meetings of the Board of Directors, subject to the execution of a waiver of the
notice thereof signed by, or the attendance at such meeting of, all Directors
who may not have received such notice.

                  SECTION 6. REGULAR MEETINGS. Regular meetings of the Board of
Directors may be held at such place, within or without the State of Delaware, as
shall from time to time be determined by the Board of Directors. After there has
been such determination, and notice thereof has been once given to each member
of the Board of Directors as hereinafter provided for special meetings, regular
meetings may be held without further notice being given.

                  SECTION 7. SPECIAL MEETINGS; NOTICE. Special meetings of the
Board of Directors shall be held whenever called by the Chairman of the Board,
if any, the President or by a majority of the Directors. Notice of each such
meeting shall be mailed to each Director, addressed to him at his residence or
usual place of business, at least five days before the date on which the meeting
is to be held, or shall be sent to him at such place by telex or facsimile, or
be delivered personally or by telephone, not later than the day before the day
on which such meeting is to be held. Each such notice shall state the time and
place of the meeting and, as may be required, the purposes thereof. Notice of
any meeting of the Board of Directors need not be given to any Director if he
shall sign a written waiver thereof either before or after the time stated
therein for

                                       5

such meeting, or if he shall be present at the meeting. Unless limited by law,
the Certificate of Incorporation, these By-laws or the terms of the notice
thereof, any and all business may be transacted at any meeting without the
notice thereof having specifically identified the matters to be acted upon.

                  SECTION 8. REMOVAL OF DIRECTORS. Any Director or the entire
Board of Directors may be removed, with or without cause, at any time, by action
of the holders of record of the majority of the issued and outstanding stock of
the Corporation (a) present in person or by proxy at a meeting of holders of
such stock and entitled to vote thereon or (b) by a consent in writing in the
manner contemplated in Section 9 of Article II, and the vacancy or vacancies in
the Board of Directors caused by any such removal may be filled by action of
such a majority at such meeting or at any subsequent meeting or by consent.

                  SECTION 9. RESIGNATIONS. Any Director of the Corporation may
resign at any time by giving written notice to the Chairman of the Board, if
any, the President, the Vice President or the Secretary of the Corporation. The
resignation of any Director shall take effect upon receipt of notice thereof or

vacancies occurring in the Board by reason of death, resignation, retirement,
disqualification or removal, with or without cause, may be filled by the action

such stock and entitled to vote thereon or (b) by a consent in writing in the
manner contemplated in Section 9 of Article II. The Director so chosen, whether
selected to fill a vacancy or elected to a new directorship, shall hold office
until the next meeting of stockholders at which the election of Directors is in

shall not receive any stated salary for their services, but, by resolution of
the Board, a specific sum fixed by the Board plus expenses may be allowed for

serving the Corporation or any parent or subsidiary corporation thereof in any
other capacity and receiving compensation therefor.

permitted to be taken at any meeting of the Board of Directors may be taken

                  SECTION 1. RIGHT OF INDEMNIFICATION. Every person now or
hereafter serving as a Director or officer of the Corporation and every such
Director or officer serving at the request of the Corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall be indemnified by the Corporation in accordance
with and to the fullest extent permitted by law for the defense of, or in

proceeding, whether civil, criminal, administrative or investigative.

                  SECTION 2. EXPENSES. Expenses incurred in defending a civil or
criminal action, suit or proceeding may be paid by the Corporation in advance of

Corporation as authorized in this Article V.

                  SECTION 3. OTHER RIGHTS OF INDEMNIFICATION. The right of
indemnification herein provided shall not be deemed exclusive of any other
rights to which any such Director or officer may now or hereafter be entitled
under any by-law, agreement, vote of stockholders or disinterested directors or

                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

                  SECTION 1. PLACE OF MEETINGS. All meetings of stockholders
shall be held at such place or places, within or without the State of Delaware,

business as may come before the meeting.

                  SECTION 3. SPECIAL MEETINGS. A special meeting of the
stockholders, or of any class thereof entitled to vote, for any purpose or
purposes, may be called at any time by the Chairman of the Board, if any, or the
President or by order of the Board of Directors and shall be called by the
Secretary upon the written request of stockholders holding of record at least
50% of the outstanding shares of stock of the Corporation entitled to vote at
such meeting. Such written request shall state the purpose or purposes for which
such meeting is to be called.

                  SECTION 4. NOTICE OF MEETINGS. Except as otherwise provided by
law, written notice of each meeting of stockholders, whether annual or special,
stating the place, date and hour of the meeting shall be given not less than ten
days or more than sixty days before the date on which the meeting is to be held
to each stockholder of record entitled to vote thereat by delivering a notice
thereof to him personally or by mailing such notice in a postage prepaid
envelope directed to him at his address as it appears on the records of the
Corporation, unless he shall have filed with the Secretary of the Corporation a
written request that notices intended for him be directed to another address, in
which case such notice shall be directed to him at the address designated in
such request. Notice shall not be required to be given to any stockholder who
shall waive such notice in writing, whether prior to or after such meeting, or
who shall attend such meeting in person or by proxy unless such attendance is
for the express purpose of objecting, at the beginning of such meeting, to the
transactions of any business because the meeting is not lawfully called or
convened. Every notice of a special meeting of the stockholders, besides the
time and place of the meeting, shall state briefly the objects or purposes
thereof.

                  SECTION 5. LIST OF STOCKHOLDERS. It shall be the duty of the
Secretary or other officer of the Corporation who shall have charge of the stock
ledger to prepare and make, at least ten days before every meeting of the
stockholders, a complete list of the stockholders entitled to vote thereat,
arranged in alphabetical order, and showing the address of each stockholder and
the number of shares registered in his name. Such list shall be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place within the city where the meeting is to be held, which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place where the meeting is to be held. The list shall be kept and produced at
the time and place of the meeting during the whole time thereof and subject to
the inspection of any stockholder who may be present. The original or duplicate
ledger shall be the only evidence as to who are the stockholders entitled to
examine such list or the books of the Corporation or to vote in person or by
proxy at such meeting.

                  SECTION 6. QUORUM. At each meeting of the stockholders, the

otherwise provided by law, the Certificate of Incorporation or these By-laws. In
the absence of a quorum, any officer entitled to preside at, or act as Secretary
of, such meeting

                                       3

                  SECTION 7. VOTING. Every stockholder of record who is entitled
to vote shall at every meeting of the stockholders be entitled to one vote for
each share of stock held by him on the record date; EXCEPT, HOWEVER, that shares
of its own stock belonging to the Corporation or to another corporation, if a
majority of the shares entitled to vote in the election of directors of such
other corporation is held by the Corporation, shall neither be entitled to vote
nor counted for quorum purposes. Nothing in this Section shall be construed as
limiting the right of the Corporation to vote its own stock held by it in a
fiduciary capacity. At all meetings of the stockholders, a quorum being present,
all matters shall be decided by majority vote of the shares of stock entitled to
vote held by stockholders present in person or by proxy, except as otherwise
required by law or the Certificate of Incorporation. Unless demanded by a
stockholder of the Corporation present in person or by proxy at any meeting of
the stockholders and entitled to vote thereat or so directed by the chairman of
the meeting or required by law, the vote thereat on any question need not be by
written ballot. On a vote by written ballot, each ballot shall be signed by the
stockholder voting, or in his name by his proxy, if there be such proxy, and
shall state the number of shares voted by him and the number of votes to which
each share is entitled.

                  SECTION 8. PROXIES. Each stockholder entitled to vote at a
meeting of stockholders or to express consent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy. A proxy acting for any stockholder shall be duly appointed by an
instrument in writing subscribed by such stockholder. No proxy shall be valid
after the expiration of three years from the date thereof unless the proxy
provides for a longer period.

                  SECTION 9. ACTION WITHOUT A MEETING. Any action required to be
taken at any annual or special meeting of stockholders or any action which may
be taken at any annual or special meeting of stockholders may be taken without a
meeting, without prior notice and without a vote, if a consent in writing
setting forth the action so taken shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted. Prompt notice of the taking of the
corporate action without a meeting by less than unanimous written consent shall
be given to those stockholders who have not consented in writing.

removed. At each annual meeting of stockholders, at which a quorum is present,
the persons receiving a plurality of the votes cast shall be the Directors.
Acceptance of the office of Director may be expressed orally or in writing, and

number as shall be determined from time to time by the Board of Directors and
initially shall be two.

                  SECTION 4. QUORUM AND MANNER OF ACTING. Unless otherwise
provided by law, the presence of 50% of the whole Board of Directors shall be
necessary to constitute a quorum for the transaction of business. In the absence
of a quorum, a majority of the Directors present may adjourn the meeting from
time to time until a quorum shall be present. Notice of any adjourned meeting
need not be given. At all meetings of Directors, a quorum being present, all
matters shall be decided by the affirmative vote of a majority of the Directors
present, except as otherwise required by law. The Board of Directors may hold
its meetings at such place or places within or without the State of Delaware as
the Board of Directors may from time to time determine or as shall be specified
in the respective notices, or waivers of notice, thereof.

shall meet at the place of the annual meeting of stockholders for the purpose of
organization, the election of officers and the transaction of other business.
Notice of such meeting need not be given. If such meeting is held at any other
time or place, notice thereof must be given as hereinafter provided for special
meetings of the Board of Directors, subject to the execution of a waiver of the
notice thereof signed by, or the attendance at such meeting of, all Directors
who may not have received such notice.

                  SECTION 6. REGULAR MEETINGS. Regular meetings of the Board of
Directors may be held at such place, within or without the State of Delaware, as
shall from time to time be determined by the Board of Directors. After there has
been such determination, and notice thereof has been once given to each member
of the Board of Directors as hereinafter provided for special meetings, regular
meetings may be held without further notice being given.

                  SECTION 7. SPECIAL MEETINGS; NOTICE. Special meetings of the
Board of Directors shall be held whenever called by the Chairman of the Board,
if any, the President or by a majority of the Directors. Notice of each such
meeting shall be mailed to each Director, addressed to him at his residence or
usual place of business, at least five days before the date on which the meeting
is to be held, or shall be sent to him at such place by telex or facsimile, or
be delivered personally or by telephone, not later than the day before the day
on which such meeting is to be held. Each such notice shall state the time and
place of the meeting and, as may be required, the purposes thereof. Notice of
any meeting of the Board of Directors need not be given to any Director if he
shall sign a written waiver thereof either before or after the time stated
therein for

                                       5

<PAGE>


such meeting, or if he shall be present at the meeting. Unless limited by law,
the Certificate of Incorporation, these By-laws or the terms of the notice
thereof, any and all business may be transacted at any meeting without the
notice thereof having specifically identified the matters to be acted upon.

                  SECTION 8. REMOVAL OF DIRECTORS. Any Director or the entire
Board of Directors may be removed, with or without cause, at any time, by action
of the holders of record of the majority of the issued and outstanding stock of
the Corporation (a) present in person or by proxy at a meeting of holders of
such stock and entitled to vote thereon or (b) by a consent in writing in the
manner contemplated in Section 9 of Article II, and the vacancy or vacancies in
the Board of Directors caused by any such removal may be filled by action of
such a majority at such meeting or at any subsequent meeting or by consent.

                  SECTION 9. RESIGNATIONS. Any Director of the Corporation may
resign at any time by giving written notice to the Chairman of the Board, if
any, the President, the Vice President or the Secretary of the Corporation. The
resignation of any Director shall take effect upon receipt of notice thereof or

specified therein, the acceptance of such resignation shall not be necessary to
make it effective.

                  SECTION 10. VACANCIES. Any newly created directorships and
vacancies occurring in the Board by reason of death, resignation, retirement,
disqualification or removal, with or without cause, may be filled by the action
of the holders of record of the majority of the issued and outstanding stock of

such stock and entitled to vote thereon or (b) by a consent in writing in the
manner contemplated in Section 9 of Article II. The Director so chosen, whether

until the next meeting of stockholders at which the election of Directors is in

shall not receive any stated salary for their services, but, by resolution of
the Board, a specific sum fixed by the Board plus expenses may be allowed for
attendance at each regular or special meeting of the Board; PROVIDED, HOWEVER,

serving the Corporation or any parent or subsidiary corporation thereof in any
other capacity and receiving compensation therefor.

                  SECTION 12. ACTION WITHOUT A MEETING. Any action required or
permitted to be taken at any meeting of the Board of Directors may be taken

persons participating in the meeting can hear each other, and such participation
shall constitute presence in person at such meeting.

indemnification herein provided shall not be deemed exclusive of any other

                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

                  SECTION 1. PLACE OF MEETINGS. All meetings of stockholders
shall be held at such place or places, within or without the State of Tennessee,

President or by order of the Board of Directors and shall be called by the
Secretary upon the written request of stockholders holding of record at least
50% of the outstanding shares of stock of the Corporation entitled to vote at
such meeting. Such written request shall state the purpose or purposes for which
such meeting is to be called.

                  SECTION 4. NOTICE OF MEETINGS. Except as otherwise provided by
law, written notice of each meeting of stockholders, whether annual or special,
stating the place, date and hour of the meeting shall be given not less than ten

Corporation, unless he shall have filed with the Secretary of the Corporation a
written request that notices intended for him be directed to another address, in
which case such notice shall be directed to him at the address designated in
such request. Notice shall not be required to be given to any stockholder who
shall waive such notice in writing, whether prior to or after such meeting, or
who shall attend such meeting in person or by proxy unless such attendance is
for the express purpose of objecting, at the beginning of such meeting, to the
transactions of any business because the meeting is not lawfully called or
convened. Every notice of a special meeting of the stockholders, besides the
time and place of the meeting, shall state briefly the objects or purposes
thereof.

                  SECTION 5. LIST OF STOCKHOLDERS. It shall be the duty of the
Secretary or other officer of the Corporation who shall have charge of the stock
ledger to prepare and make, at least ten days before every meeting of the

ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place within the city where the meeting is to be held, which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place where the meeting is to be held. The list shall be kept and produced at
the time and place of the meeting during the whole time thereof and subject to
the inspection of any stockholder who may be present. The original or duplicate
ledger shall be the only evidence as to who are the stockholders entitled to

each share of stock held by him on the record date; EXCEPT, HOWEVER, that shares
of its own stock belonging to the Corporation or to another corporation, if a
majority of the shares entitled to vote in the election of directors of such
other corporation is held by the Corporation, shall neither be entitled to vote
nor counted for quorum purposes. Nothing in this Section shall be construed as
limiting the right of the Corporation to vote its own stock held by it in a
fiduciary capacity. At all meetings of the stockholders, a quorum being present,
all matters shall be decided by majority vote of the shares of stock entitled to
vote held by stockholders present in person or by proxy, except as otherwise
required by law or the Certificate of Incorporation. Unless demanded by a
stockholder of the Corporation present in person or by proxy at any meeting of
the stockholders and entitled to vote thereat or so directed by the chairman of
the meeting or required by law, the vote thereat on any question need not be by
written ballot. On a vote by written ballot, each ballot shall be signed by the
stockholder voting, or in his name by his proxy, if there be such proxy, and
shall state the number of shares voted by him and the number of votes to which
each share is entitled.

                  SECTION 8. PROXIES. Each stockholder entitled to vote at a
meeting of stockholders or to express consent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy. A proxy acting for any stockholder shall be duly appointed by an

taken at any annual or special meeting of stockholders or any action which may
be taken at any annual or special meeting of stockholders may be taken without a
meeting, without prior notice and without a vote, if a consent in writing
setting forth the action so taken shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted. Prompt notice of the taking of the
corporate action without a meeting by less than unanimous written consent shall
be given to those stockholders who have not consented in writing.

                                   ARTICLE III

removed. At each annual meeting of stockholders, at which a quorum is present,
the persons receiving a plurality of the votes cast shall be the Directors.

number as shall be determined from time to time by the Board of Directors and
initially shall be two.

                  SECTION 4. QUORUM AND MANNER OF ACTING. Unless otherwise
provided by law, the presence of 50% of the whole Board of Directors shall be
necessary to constitute a quorum for the transaction of business. In the absence
of a quorum, a majority of the Directors present may adjourn the meeting from
time to time until a quorum shall be present. Notice of any adjourned meeting
need not be given. At all meetings of Directors, a quorum being present, all
matters shall be decided by the affirmative vote of a majority of the Directors
present, except as otherwise required by law. The Board of Directors may hold
its meetings at such place or places within or without the State of Tennessee as
the Board of Directors may from time to time determine or as shall be specified
in the respective notices, or waivers of notice, thereof.

                  SECTION 5. ORGANIZATION MEETING. Immediately after each annual
meeting of stockholders for the election of Directors the Board of Directors
shall meet at the place of the annual meeting of stockholders for the purpose of
organization, the election of officers and the transaction of other business.
Notice of such meeting need not be given. If such meeting is held at any other
time or place, notice thereof must be given as hereinafter provided for special
meetings of the Board of Directors, subject to the execution of a waiver of the
notice thereof signed by, or the attendance at such meeting of, all Directors
who may not have received such notice.

Directors may be held at such place, within or without the State of Tennessee,
as shall from time to time be determined by the Board of Directors. After there
has been such determination, and notice thereof has been once given to each
member of the Board of Directors as hereinafter provided for special meetings,
regular meetings may be held without further notice being given.

                  SECTION 7. SPECIAL MEETINGS; NOTICE. Special meetings of the
Board of Directors shall be held whenever called by the Chairman of the Board,
if any, the President or by a majority of the Directors. Notice of each such
meeting shall be mailed to each Director, addressed to him at his residence or
usual place of business, at least five days before the date on which the meeting
is to be held, or shall be sent to him at such place by telex or facsimile, or
be delivered personally or by telephone, not later than the day before the day
on which such meeting is to be held. Each such notice shall state the time and
place of the meeting and, as may be required, the purposes thereof. Notice of
any meeting of the Board of Directors need not be given to any Director if he
shall sign a written waiver thereof either before or after the time stated
therein for

                                       5

                  SECTION 8. REMOVAL OF DIRECTORS. Any Director or the entire
Board of Directors may be removed, with or without cause, at any time, by action
of the holders of record of the majority of the issued and outstanding stock of

resign at any time by giving written notice to the Chairman of the Board, if
any, the President, the Vice President or the Secretary of the Corporation. The
resignation of any Director shall take effect upon receipt of notice thereof or
at such later time as shall be specified in such notice; and, unless otherwise
specified therein, the acceptance of such resignation shall not be necessary to
make it effective.

thereof.

                  SECTION 5. LIST OF STOCKHOLDERS. It shall be the duty of the

member of the Board of Directors as hereinafter provided for special meetings,
regular meetings may be held without further notice being given.

                  SECTION 7. SPECIAL MEETINGS; NOTICE. Special meetings of the
Board of Directors shall be held whenever called by the Chairman of the Board,

the Certificate of Incorporation, these By-laws or the terms of the notice
thereof, any and all business may be transacted at any meeting without the
notice thereof having specifically identified the matters to be acted upon.

                  SECTION 8. REMOVAL OF DIRECTORS. Any Director or the entire
Board of Directors may be removed, with or without cause, at any time, by action
of the holders of record of the majority of the issued and outstanding stock of
the Corporation (a) present in person or by proxy at a meeting of holders of
such stock and entitled to vote thereon or (b) by a consent in writing in the
manner contemplated in Section 9 of Article II, and the vacancy or vacancies in
the Board of Directors caused by any such removal may be filled by action of
such a majority at such meeting or at any subsequent meeting or by consent.

                  SECTION 9. RESIGNATIONS. Any Director of the Corporation may
resign at any time by giving written notice to the Chairman of the Board, if
any, the President, the Vice President or the Secretary of the Corporation. The
resignation of any Director shall take effect upon receipt of notice thereof or
at such later time as shall be specified in such notice; and, unless otherwise
specified therein, the acceptance of such resignation shall not be necessary to

such stock and entitled to vote thereon or (b) by a consent in writing in the

selected to fill a vacancy or elected to a new directorship, shall hold office
until the next meeting of stockholders at which the election of Directors is in
the regular order of business, and until his successor has been elected and
qualifies, or until he sooner dies, resigns or is removed.

                  SECTION 11. COMPENSATION OF DIRECTORS. Directors, as such,
shall not receive any stated salary for their services, but, by resolution of
the Board, a specific sum fixed by the Board plus expenses may be allowed for
attendance at each regular or special meeting of the board; PROVIDED, HOWEVER,
that nothing herein contained shall be construed to preclude any Director from
serving the Corporation or any parent or subsidiary corporation thereof in any
other capacity and receiving compensation therefor.

                  SECTION 12. ACTION WITHOUT A MEETING. Any action required or
permitted to be taken at any meeting of the Board of Directors may be taken
without a meeting if a written consent thereto is signed by all members of the
Board, and such written consent is filed with the minutes or proceedings of the
Board.

                  SECTION 13. TELEPHONIC PARTICIPATION IN MEETINGS. Members of

conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other, and such participation
shall constitute presence in person at such meeting.

                    INDEMNIFICATION OF OFFICERS AND DIRECTORS

                  SECTION 1. RIGHT OF INDEMNIFICATION. Every person now or
hereafter serving as a Director or officer of the Corporation and every such
Director or officer serving at the request of the Corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall be indemnified by the Corporation in accordance
with and to the fullest extent permitted by law for the defense of, or in
connection with, any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative.

                  SECTION 2. EXPENSES. Expenses incurred in defending a civil or
criminal action, suit or proceeding may be paid by the Corporation in advance of

                  SECTION 3. OTHER RIGHTS OF INDEMNIFICATION. The right of
indemnification herein provided shall not be deemed exclusive of any other
rights to which any such Director or officer may now or hereafter be entitled

                                   ----------

                                    ARTICLE I

                                     OFFICES

                  The registered office of the Corporation in the State of

                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

                  SECTION 1. PLACE OF MEETINGS. All meetings of stockholders

for the election of Directors and the transaction of other business shall be

                  SECTION 3. SPECIAL MEETINGS. A special meeting of the
stockholders, or of any class thereof entitled to vote, for any purpose or
purposes, may be called at any time by the Chairman of the Board, if any, or the
President or by order of the Board of Directors and shall be called by the
Secretary upon the written request of stockholders holding of record at least
50% of the outstanding shares of stock of the Corporation entitled to vote at
such meeting. Such written request shall state the purpose or purposes for which
such meeting is to be called.

                  SECTION 4. NOTICE OF MEETINGS. Except as otherwise provided by
law, written notice of each meeting of stockholders, whether annual or special,
stating the place, date and hour of the meeting shall be given not less than ten
days or more than sixty days before the date on which the meeting is to be held
to each stockholder of record entitled to vote thereat by delivering a notice
thereof to him personally or by mailing such notice in a postage prepaid
envelope directed to him at his address as it appears on the records of the
Corporation, unless he shall have filed with the Secretary of the Corporation a
written request that notices intended for him be directed to another address, in
which case such notice shall be directed to him at the address designated in
such request. Notice shall not be required to be given to any stockholder who
shall waive such notice in writing, whether prior to or after such meeting, or
who shall attend such meeting in person or by proxy unless such attendance is
for the express purpose of objecting, at the beginning of such meeting, to the
transactions of any business because the meeting is not lawfully called or
convened. Every notice of a special meeting of the stockholders, besides the
time and place of the meeting, shall state briefly the objects or purposes
thereof.

                  SECTION 5. LIST OF STOCKHOLDERS. It shall be the duty of the
Secretary or other officer of the Corporation who shall have charge of the stock
ledger to prepare and make, at least ten days before every meeting of the
stockholders, a complete list of the stockholders entitled to vote thereat,
arranged in alphabetical order, and showing the address of each stockholder and
the number of shares registered in his name. Such list shall be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place within the city where the meeting is to be held, which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place where the meeting is to be held. The list shall be kept and produced at
the time and place of the meeting during the whole time thereof and subject to
the inspection of any stockholder who may be present. The original or duplicate
ledger shall be the only evidence as to who are the stockholders entitled to
examine such list or the books of the Corporation or to vote in person or by
proxy at such meeting.

                  SECTION 6. QUORUM. At each meeting of the stockholders, the

Corporation entitled to vote at such meeting, present in person or by proxy,
shall constitute a quorum for the transaction of business, except where
otherwise provided by law, the Certificate of Incorporation or these By-laws. In
the absence of a quorum, any officer entitled to preside at, or act as Secretary
of, such meeting shall have the power to adjourn the meeting from time to time
until a quorum shall be constituted.

<PAGE>


                  SECTION 7. VOTING. Every stockholder of record who is entitled
to vote shall at every meeting of the stockholders be entitled to one vote for
each share of stock held by him on the record date; EXCEPT, HOWEVER, that shares
of its own stock belonging to the Corporation or to another corporation, if a
majority of the shares entitled to vote in the election of directors of such
other corporation is held by the Corporation, shall neither be entitled to vote
nor counted for quorum purposes. Nothing in this Section shall be construed as
limiting the right of the Corporation to vote its own stock held by it in a
fiduciary capacity. At all meetings of the stockholders, a quorum being present,
all matters shall be decided by majority vote of the shares of stock entitled to
vote held by stockholders present in person or by proxy, except as otherwise
required by law or the Certificate of Incorporation. Unless demanded by a
stockholder of the Corporation present in person or by proxy at any meeting of
the stockholders and entitled to vote thereat or so directed by the chairman of
the meeting or required by law, the vote thereat on any question need not be by
written ballot. On a vote by written ballot, each ballot shall be signed by the
stockholder voting, or in his name by his proxy, if there be such proxy, and
shall state the number of shares voted by him and the number of votes to which
each share is entitled.

                  SECTION 8. PROXIES. Each stockholder entitled to vote at a
meeting of stockholders or to express consent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy. A proxy acting for any stockholder shall be duly appointed by an
instrument in writing subscribed by such stockholder. No proxy shall be valid
after the expiration of three years from the date thereof unless the proxy
provides for a longer period.

                  SECTION 9. ACTION WITHOUT A MEETING. Any action required to be
taken at any annual or special meeting of stockholders or any action which may
be taken at any annual or special meeting of stockholders may be taken without a
meeting, without prior notice and without a vote, if a consent in writing
setting forth the action so taken shall be signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares entitled to
vote thereon were present and voted. Prompt notice of the taking of the
corporate action without a meeting by less than unanimous written consent shall
be given to those stockholders who have not consented in writing.

                                   ARTICLE III

                               BOARD OF DIRECTORS

                  SECTION 1. POWERS. The business and affairs of the Corporation
shall be managed under the direction of the Board of Directors.

                  SECTION 2. ELECTION AND TERM. Except as otherwise provided by
law, Directors shall be elected at the annual meeting of stockholders and shall
hold office until the next annual meeting of stockholders and until their
successors are elected and qualify, or until they sooner die, resign or are
removed. At each annual meeting of stockholders, at which a quorum is

                                       4

<PAGE>


present, the persons receiving a plurality of the votes cast shall be the
Directors. Acceptance of the office of Director may be expressed orally or in
writing, and attendance at the organization meeting shall constitute such
acceptance.

                  SECTION 3. NUMBER. The number of Directors shall be such
number as shall be determined from time to time by the Board of Directors and
initially shall be two.

                  SECTION 4. QUORUM AND MANNER OF ACTING. Unless otherwise
provided by law, the presence of 50% of the whole Board of Directors shall be
necessary to constitute a quorum for the transaction of business. In the absence
of a quorum, a majority of the Directors present may adjourn the meeting from
time to time until a quorum shall be present. Notice of any adjourned meeting
need not be given. At all meetings of Directors, a quorum being present, all
matters shall be decided by the affirmative vote of a majority of the Directors
present, except as otherwise required by law. The Board of Directors may hold
its meetings at such place or places within or without the State of Nevada as
the Board of Directors may from time to time determine or as shall be specified
in the respective notices, or waivers of notice, thereof.

                  SECTION 5. ORGANIZATION MEETING. Immediately after each annual
meeting of stockholders for the election of Directors the Board of Directors
shall meet at the place of the annual meeting of stockholders for the purpose of
organization, the election of officers and the transaction of other business.
Notice of such meeting need not be given. If such meeting is held at any other
time or place, notice thereof must be given as hereinafter provided for special
meetings of the Board of Directors, subject to the execution of a waiver of the
notice thereof signed by, or the attendance at such meeting of, all Directors
who may not have received such notice.

                  SECTION 6. REGULAR MEETINGS. Regular meetings of the Board of
Directors may be held at such place, within or without the State of Nevada, as
shall from time to time be determined by the Board of Directors. After there has
been such determination, and notice thereof has been once given to each member
of the Board of Directors as hereinafter provided for special meetings, regular
meetings may be held without further notice being given.

                  SECTION 7. SPECIAL MEETINGS; NOTICE. Special meetings of the
Board of Directors shall be held whenever called by the Chairman of the Board,
if any, the President or by a majority of the Directors. Notice of each such
meeting shall be mailed to each Director, addressed to him at his residence or
usual place of business, at least five days before the date on which the meeting
is to be held, or shall be sent to him at such place by telex or facsimile, or
be delivered personally or by telephone, not later than the day before the day
on which such meeting is to be held. Each such notice shall state the time and
place of the meeting and, as may be required, the purposes thereof. Notice of
any meeting of the Board of Directors need not be given to any Director if he
shall sign a written waiver thereof either before or after the time stated
therein for such meeting, or if he shall be present at the meeting. Unless
limited by law, the Certificate of Incorporation, these By-laws or the terms of
the notice thereof, any and all business may be transacted at any meeting
without the notice thereof having specifically identified the matters to be
acted upon.

                  SECTION 8. REMOVAL OF DIRECTORS. Any Director or the entire
Board of Directors may be removed, with or without cause, at any time, by action
of the holders of record of the majority of the issued and outstanding stock of
the Corporation (a) present in person or by proxy at a meeting of holders of
such stock and entitled to vote thereon or (b) by a consent in writing in the
manner contemplated in Section 9 of Article II, and the vacancy or vacancies in
the Board of Directors caused by any such removal may be filled by action of
such a majority at such meeting or at any subsequent meeting or by consent.

                  SECTION 9. RESIGNATIONS. Any Director of the Corporation may
resign at any time by giving written notice to the Chairman of the Board, if
any, the President, the Vice President or the Secretary of the Corporation. The
resignation of any Director shall take effect upon receipt of notice thereof or
at such later time as shall be specified in such notice; and, unless otherwise
specified therein, the acceptance of such resignation shall not be necessary to
make it effective.

                  SECTION 10. VACANCIES. Any newly created directorships and

distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a date as a
record date for any such determination of stockholders. Such record date shall
not be more than sixty or less than ten days before the date of such meeting, or

such meeting is to be called.

               SECTION 4. NOTICE OF MEETINGS.  Except as  otherwise  provided by
law, written notice of each meeting of stockholders,  whether annual or special,
stating the place, date and hour of the meeting shall be given not less than ten
days or more than sixty days  before the date on which the meeting is to be held
to each  stockholder  of record  entitled to vote thereat by delivering a notice
thereof  to him  personally  or by  mailing  such  notice in a  postage  prepaid
envelope  directed  to him at his  address as it  appears on the  records of the
Corporation,  unless he shall have filed with the Secretary of the Corporation a
written request that notices intended for him be directed to another address, in
which case such notice  shall be directed  to him at the address  designated  in
such request.  Notice shall not be required to be given to any  stockholder  who
shall waive such notice in writing,  whether prior to or after such meeting,  or
who shall attend such meeting in person or by proxy  unless such  attendance  is
for the express purpose of objecting,  at the beginning of such meeting,  to the
transactions  of any  business  because  the meeting is not  lawfully  called or
convened.  Every notice of a special  meeting of the  stockholders,  besides the
time and place of the  meeting,  shall  state  briefly  the  objects or purposes
thereof.

               SECTION  5.  LIST OF  STOCKHOLDERS.  It  shall be the duty of the
Secretary or other officer of the Corporation who shall have charge of the stock
ledger to  prepare  and make,  at least ten days  before  every  meeting  of the
stockholders,  a complete  list of the  stockholders  entitled to vote  thereat,
arranged in alphabetical  order, and showing the address of each stockholder and
the  number of shares  registered  in his name.  Such list  shall be open to the
examination of any stockholder,  for any purpose germane to the meeting,  during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place  within the city where the meeting is to be held,  which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place  where the meeting is to be held.  The list shall be kept and  produced at
the time and place of the meeting  during the whole time  thereof and subject to
the inspection of any stockholder who may be present.  The original or duplicate
ledger  shall be the only  evidence as to who are the  stockholders  entitled to
examine  such  list or the books of the  Corporation  or to vote in person or by
proxy at such meeting.

               SECTION  6.  QUORUM.  At each  meeting of the  stockholders,  the
holders of record of a  majority  of the  issued  and  outstanding  stock of the
Corporation  entitled  to vote at such  meeting,  present in person or by proxy,
shall  constitute  a  quorum  for the  transaction  of  business,  except  where
otherwise provided by law, the Certificate of Incorporation or these By-laws. In

                                       3
<PAGE>

the absence of a quorum, any officer entitled to preside at, or act as Secretary
of, such  meeting  shall have the power to adjourn the meeting from time to time
until a quorum shall be constituted.

               SECTION 7. VOTING. Every stockholder of record who is entitled to
vote shall at every meeting of the stockholders be entitled to one vote for each
share of stock held by him on the record date; EXCEPT,  HOWEVER,  that shares of
its own stock  belonging  to the  Corporation  or to another  corporation,  if a
majority of the shares  entitled to vote in the  election of  directors  of such
other corporation is held by the Corporation,  shall neither be entitled to vote
nor counted for quorum  purposes.  Nothing in this Section shall be construed as
limiting  the right of the  Corporation  to vote its own  stock  held by it in a
fiduciary capacity. At all meetings of the stockholders, a quorum being present,
all matters shall be decided by majority vote of the shares of stock entitled to
vote held by  stockholders  present in person or by proxy,  except as  otherwise
required  by law or the  Certificate  of  Incorporation.  Unless  demanded  by a
stockholder of the  Corporation  present in person or by proxy at any meeting of
the  stockholders and entitled to vote thereat or so directed by the chairman of
the meeting or required by law, the vote thereat on any question  need not be by
written ballot. On a vote by written ballot,  each ballot shall be signed by the
stockholder  voting,  or in his name by his proxy,  if there be such proxy,  and
shall  state the number of shares  voted by him and the number of votes to which
each share is entitled.

               SECTION  8.  PROXIES.  Each  stockholder  entitled  to  vote at a
meeting of  stockholders  or to express  consent to corporate  action in writing
without a meeting  may  authorize  another  person or  persons to act for him by
proxy.  A proxy  acting  for any  stockholder  shall  be  duly  appointed  by an
instrument in writing  subscribed by such  stockholder.  No proxy shall be valid
after the  expiration  of three  years  from the date  thereof  unless the proxy
provides for a longer period.

               SECTION 9. ACTION  WITHOUT A MEETING.  Any action  required to be
taken at any annual or special  meeting of  stockholders or any action which may
be taken at any annual or special meeting of stockholders may be taken without a
meeting,  without  prior  notice  and  without a vote,  if a consent  in writing
setting forth the action so taken shall be signed by the holders of  outstanding
stock  having not less than the minimum  number of votes that would be necessary
to  authorize  or take such action at a meeting at which all shares  entitled to
vote  thereon  were  present  and  voted.  Prompt  notice  of the  taking of the
corporate action without a meeting by less than unanimous  written consent shall
be given to those stockholders who have not consented in writing.

removed.  At each annual meeting of stockholders,  at which a quorum is present,
the  persons  receiving a  plurality  of the votes cast shall be the  Directors.
Acceptance of the office of Director may be expressed orally or in writing,  and
attendance at the organization meeting shall constitute such acceptance.

               SECTION 3. NUMBER.  The number of Directors  shall be such number
as shall be determined from time to time by the Board of Directors and initially
shall be two.

               SECTION 4. QUORUM AND MANNER OF ACTING. Unless otherwise provided
by law, the  presence of 50% of the whole Board of Directors  shall be necessary
to  constitute a quorum for the  transaction  of  business.  In the absence of a
quorum, a majority of the Directors present may adjourn the meeting from time to
time until a quorum shall be present.  Notice of any adjourned  meeting need not
be given.  At all meetings of  Directors,  a quorum being  present,  all matters
shall be decided by the affirmative vote of a majority of the Directors present,
except  as  otherwise  required  by law.  The  Board of  Directors  may hold its
meetings  at such place or places  within or  without  the State of Texas as the
Board of Directors  may from time to time  determine or as shall be specified in
the respective notices, or waivers of notice, thereof.

               SECTION 5.  ORGANIZATION  MEETING.  Immediately after each annual
meeting of  stockholders  for the election of  Directors  the Board of Directors
shall meet at the place of the annual meeting of stockholders for the purpose of
organization,  the election of officers and the  transaction of other  business.
Notice of such meeting  need not be given.  If such meeting is held at any other
time or place, notice thereof must be given as hereinafter  provided for special
meetings of the Board of Directors,  subject to the execution of a waiver of the
notice  thereof  signed by, or the  attendance at such meeting of, all Directors
who may not have received such notice.

               SECTION 6.  REGULAR  MEETINGS.  Regular  meetings of the Board of
Directors  may be held at such place,  within or without the State of Texas,  as
shall from time to time be determined by the Board of Directors. After there has
been such  determination,  and notice thereof has been once given to each member
of the Board of Directors as hereinafter provided for special meetings,  regular
meetings may be held without further notice being given.

               SECTION 7.  SPECIAL  MEETINGS;  NOTICE.  Special  meetings of the
Board of Directors  shall be held whenever  called by the Chairman of the Board,
if any,  the  President or by a majority of the  Directors.  Notice of each such
meeting shall be mailed to each  Director,  addressed to him at his residence or
usual place of business, at least five days before the date on which the meeting
is to be held, or shall be sent to him at such place by telex or  facsimile,  or
be delivered  personally or by telephone,  not later than the day before the day
on which such  meeting is to be held.  Each such notice shall state the time and
place of the meeting and, as may be required,  the


                                       5
<PAGE>

purposes  thereof.  Notice of any meeting of the Board of Directors  need not be
given to any Director if he shall sign a written waiver thereof either before or
after the time stated therein for such meeting, or if he shall be present at the
meeting. Unless limited by law, the Certificate of Incorporation,  these By-laws
or the terms of the notice  thereof,  any and all business may be  transacted at
any meeting  without  the notice  thereof  having  specifically  identified  the
matters to be acted upon.

               SECTION 8. REMOVAL OF DIRECTORS. Any Director or the entire Board
of Directors may be removed,  with or without  cause,  at any time, by action of
the holders of record of the majority of the issued and outstanding stock of the
Corporation  (a)  present  in person or by proxy at a meeting of holders of such
stock and  entitled to vote thereon or (b) by a consent in writing in the manner
contemplated  in Section 9 of Article  II, and the vacancy or  vacancies  in the
Board of Directors  caused by any such removal may be filled by action of such a
majority at such meeting or at any subsequent meeting or by consent.

               SECTION 9.  RESIGNATIONS.  Any  Director of the  Corporation  may
resign at any time by giving  written  notice to the  Chairman of the Board,  if
any, the President, the Vice President or the Secretary of the Corporation.  The
resignation  of any Director shall take effect upon receipt of notice thereof or
at such later time as shall be specified in such notice;  and, unless  otherwise
specified therein,  the acceptance of such resignation shall not be necessary to
make it effective.

               SECTION  10.  VACANCIES.  Any  newly  created  directorships  and
vacancies  occurring in the Board by reason of death,  resignation,  retirement,
disqualification or removal,  with or without cause, may be filled by the action
of the holders of record of the majority of the issued and outstanding  stock of
the  Corporation  (a)  present  in person or by proxy at a meeting of holders of
such stock and  entitled  to vote  thereon or (b) by a consent in writing in the
manner contemplated in Section 9 of Article II. The Director so chosen,  whether
selected to fill a vacancy or elected to a new  directorship,  shall hold office
until the next meeting of  stockholders at which the election of Directors is in
the regular  order of  business,  and until his  successor  has been elected and
qualifies, or until he sooner dies, resigns or is removed.

               SECTION 11. COMPENSATION OF DIRECTORS.  Directors, as such, shall
not receive any stated  salary for their  services,  but, by  resolution  of the
Board,  a specific  sum fixed by the Board  plus  expenses  may be  allowed  for
attendance at each regular or special meeting of the Board;  PROVIDED,  HOWEVER,
that nothing herein  contained  shall be construed to preclude any Director from
serving the Corporation or any parent or subsidiary  corporation  thereof in any
other capacity and receiving compensation therefor.

               SECTION  12.  ACTION  WITHOUT A MEETING.  Any action  required or
permitted  to be taken at any  meeting  of the Board of  Directors  may be taken
without a meeting if a written  consent  thereto is signed by all members of the
Board,  and such written consent is filed with the minutes or proceedings of the
Board.

Board  of  Directors  may  participate  in a  meeting  of the  Board by means of
conference telephone or similar  communications  equipment by means of which all
persons participating in the meeting can hear each other, and such participation
shall constitute presence in person at such meeting.

               SECTION  1.  RIGHT  OF  INDEMNIFICATION.   Every  person  now  or
hereafter  serving as a Director  or officer of the  Corporation  and every such
Director  or officer  serving at the request of the  Corporation  as a director,
officer, employee or agent of another corporation,  partnership,  joint venture,
trust or other enterprise, shall be indemnified by the Corporation in accordance
with and to the  fullest  extent  permitted  by law for the  defense  of,  or in

                  SECTION 4. NOTICE OF MEETINGS. Except as otherwise provided by
law, written notice of each meeting of stockholders,  whether annual or special,

thereof  to him  personally  or by  mailing  such  notice in a  postage  prepaid
envelope  directed  to him at his  address as it  appears on the  records of the
Corporation,  unless he shall have filed with the Secretary of the Corporation a
written request that notices intended for him be directed to another address, in
which case such notice  shall be directed  to him at the address  designated  in
such request.  Notice shall not be required to be given to any  stockholder  who
shall waive such notice in writing,  whether prior to or after such meeting,  or
who shall attend such meeting in person or by proxy  unless such  attendance  is
for the express purpose of objecting,  at the beginning of such meeting,  to the
transactions  of any  business  because  the meeting is not  lawfully  called or
convened.  Every notice of a special  meeting of the  stockholders,  besides the
time and place of the  meeting,  shall  state  briefly  the  objects or purposes
thereof.

                  SECTION 5. LIST OF  STOCKHOLDERS.  It shall be the duty of the
Secretary or other officer of the Corporation who shall have charge of the stock
ledger to  prepare  and make,  at least ten days  before  every  meeting  of the
stockholders,  a complete  list of the  stockholders  entitled to vote  thereat,
arranged in alphabetical  order, and showing the address of each stockholder and
the  number of shares  registered  in his name.  Such list  shall be open to the
examination of any stockholder,  for any purpose germane to the meeting,  during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place  within the city where the meeting is to be held,  which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place  where the meeting is to be held.  The list shall be kept and  produced at
the time and place of the meeting  during the whole time  thereof and subject to
the inspection of any stockholder who may be present.  The original or duplicate
ledger  shall be the only  evidence as to who are the  stockholders  entitled to
examine  such  list or the books of the  Corporation  or to vote in person or by
proxy at such meeting.

                  SECTION 6. QUORUM.  At each meeting of the  stockholders,  the
holders of record of a  majority  of the  issued  and  outstanding  stock of the
Corporation  entitled  to vote at such  meeting,  present in person or by proxy,
shall  constitute  a  quorum  for the  transaction  of  business,  except  where
otherwise provided by law, the Certificate of Incorporation or these By-laws. In
the absence of a quorum, any officer entitled to preside at, or act as Secretary
of, such  meeting  shall have the power to adjourn the meeting from time to time
until a quorum shall be constituted.

                  SECTION 7. VOTING. Every stockholder of record who is entitled
to vote shall at every meeting of the  stockholders  be entitled to one vote for
each share of stock held by him on the record date; EXCEPT, HOWEVER, that shares
of its own stock  belonging to the Corporation or to another  corporation,  if a
majority of the shares  entitled to vote in the  election of  directors  of such
other corporation is held by the Corporation,  shall neither be entitled to vote
nor counted for quorum  purposes.  Nothing in this Section shall be construed as
limiting  the right of the  Corporation  to vote its own  stock  held by it in a
fiduciary capacity. At all meetings of the stockholders, a quorum being present,
all matters shall be decided by majority vote of the shares of stock entitled to
vote held by  stockholders  present in person or by proxy,  except as  otherwise
required  by law or the  Certificate  of  Incorporation.  Unless  demanded  by a
stockholder of the  Corporation  present in person or by proxy at any meeting of
the  stockholders and entitled to vote thereat or so directed by the chairman of
the meeting or required by law, the vote thereat on any question  need not be by
written ballot. On a vote by written ballot,  each ballot shall be signed by the
stockholder  voting,  or in his name by his proxy,  if there be such proxy,  and
shall  state the number of shares  voted by him and the number of votes to which
each share is entitled.

                  SECTION 8.  PROXIES.  Each  stockholder  entitled to vote at a
meeting of  stockholders  or to express  consent to corporate  action in writing
without a meeting  may  authorize  another  person or  persons to act for him by
proxy.  A proxy  acting  for any  stockholder  shall  be  duly  appointed  by an
instrument in writing  subscribed by such  stockholder.  No proxy shall be valid
after the  expiration  of three  years  from the date  thereof  unless the proxy
provides for a longer period.

                  SECTION 9. ACTION WITHOUT A MEETING. Any action required to be
taken at any annual or special  meeting of  stockholders or any action which may
be taken at any annual or special meeting of stockholders may be taken without a
meeting,  without  prior  notice  and  without a vote,  if a consent  in writing
setting forth the action so taken shall be signed by the holders of  outstanding
stock  having not less than the minimum  number of votes that would be necessary
to  authorize  or take such action at a meeting at which all shares  entitled to
vote  thereon  were  present  and  voted.  Prompt  notice  of the  taking of the
corporate action without a meeting by less than unanimous  written consent shall
be given to those stockholders who have not consented in writing.

present,  the  persons  receiving  a  plurality  of the votes  cast shall be the
Directors.  Acceptance  of the office of Director may be expressed  orally or in
writing,  and  attendance  at the  organization  meeting shall  constitute  such
acceptance.

                  SECTION 3.  NUMBER.  The number  of   Directors  shall be such
number as shall be  determined  from  time to time by the Board of Directors and
initially shall be two.

                  SECTION  4.  QUORUM AND  MANNER OF  ACTING.  Unless  otherwise
provided by law, the  presence of 50% of the whole Board of  Directors  shall be
necessary to constitute a quorum for the transaction of business. In the absence
of a quorum,  a majority of the  Directors  present may adjourn the meeting from
time to time until a quorum shall be present.  Notice of any  adjourned  meeting
need not be given.  At all meetings of Directors,  a quorum being  present,  all
matters shall be decided by the affirmative  vote of a majority of the Directors

for  certificates  which  shall  become  mutilated  or shall be lost,  stolen or
destroyed,  proper evidence of such loss, theft, mutilation or destruction shall
be procured for the Board of Directors, if it so requires.

                  SECTION 8. RECORD DATES.  For the purpose of  determining  the
stockholders  entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or entitled to receive payment of any dividend or other
distribution  or allotment of any rights,  or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful  action,  the Board of Directors  may fix, in advance,  a date as a

Certificate of  Incorporation,  the Board of Directors may, out of funds legally
available therefor, at any regular or special meeting declare dividends upon the
capital  stock  of the  Corporation  as and when  they  deem  expedient.  Before
declaring  any  dividend  there  may  be set  apart  out  of  any  funds  of the
Corporation  available for dividends such sum or sums as the Directors from time
to time in their discretion deem proper for working capital or as a reserve fund
to meet contingencies or for equalizing  dividends or for such other purposes as

                                    ARTICLE I

Corporation's business.


                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

               SECTION 1. PLACE OF MEETINGS.  All meetings of stockholders shall
be held at such place or places,  within or without the State of Nevada,  as may
from time to time be fixed by the Board of  Directors,  or as shall be specified
in the respective notices, or waivers of notice, thereof.

               SECTION 2. ANNUAL MEETING. The annual meeting of stockholders for
the election of Directors and the transaction of other business shall be held on
such date and at such place as may be designated  by the Board of Directors.  At

               SECTION  3.   SPECIAL   MEETINGS.   A  special   meeting  of  the
stockholders,  or of any class  thereof  entitled  to vote,  for any  purpose or
purposes, may be called at any time by the Chairman of the Board, if any, or the
President  or by order of the  Board of  Directors  and  shall be  called by the
Secretary upon the written  request of  stockholders  holding of record at least
50% of the outstanding  shares of stock of the  Corporation  entitled to vote at
such meeting. Such written request shall state the purpose or purposes for which
such meeting is to be called.

               SECTION 4. NOTICE OF MEETINGS.  Except as  otherwise  provided by
law, written notice of each meeting of stockholders,  whether annual or special,
stating the place, date and hour of the meeting shall be given not less than ten
days or more than sixty days  before the date on which the meeting is to be held
to each  stockholder  of record  entitled to vote thereat by delivering a notice
thereof  to him  personally  or by  mailing  such  notice in a  postage  prepaid
envelope  directed  to him at his  address as it  appears on the  records of the
Corporation,  unless he shall have filed with the Secretary of the Corporation a
written request that notices intended for him be directed to another address, in
which case such notice  shall be directed  to him at the address  designated  in
such request.  Notice shall not be required to be given to any  stockholder  who
shall waive such notice in writing,  whether prior to or after such meeting,  or
who shall attend such meeting in person or by proxy  unless such  attendance  is
for the express purpose of objecting,  at the beginning of such meeting,  to the
transactions  of any  business  because  the meeting is not  lawfully  called or
convened.  Every notice of a special  meeting of the  stockholders,  besides the
time and place of the  meeting,  shall  state  briefly  the  objects or purposes
thereof.

               SECTION  5.  LIST OF  STOCKHOLDERS.  It  shall be the duty of the
Secretary or other officer of the Corporation who shall have charge of the stock
ledger to  prepare  and make,  at least ten days  before  every  meeting  of the
stockholders,  a complete  list of the  stockholders  entitled to vote  thereat,
arranged in alphabetical  order, and showing the address of each stockholder and
the  number of shares  registered  in his name.  Such list  shall be open to the
examination of any stockholder,  for any purpose germane to the meeting,  during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place  within the city where the meeting is to be held,  which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place  where the meeting is to be held.  The list shall be kept and  produced at
the time and place of the meeting  during the whole time  thereof and subject to
the inspection of any stockholder who may be present.  The original or duplicate
ledger  shall be the only  evidence as to who are the  stockholders  entitled to
examine  such  list or the books of the  Corporation  or to vote in person or by
proxy at such meeting.

               SECTION  6.  QUORUM.  At each  meeting of the  stockholders,  the
holders of record of a  majority  of the  issued  and  outstanding  stock of the
Corporation  entitled  to vote at such  meeting,  present in person or by proxy,
shall  constitute  a  quorum  for the  transaction  of  business,  except  where
otherwise provided by law, the Certificate of Incorporation or these By-laws. In
the absence of a quorum, any officer entitled to preside at, or act as Secretary
of, such  meeting  shall have the power to adjourn the meeting from time to time
until a quorum shall be constituted.

               SECTION 7. VOTING. Every stockholder of record who is entitled to
vote shall at every meeting of the stockholders be entitled to one vote for each
share of stock held by him on the record date; EXCEPT,  HOWEVER,  that shares of
its own stock  belonging  to the  Corporation  or to another  corporation,  if a
majority of the shares  entitled to vote in the  election of  directors  of such
other corporation is held by the Corporation,  shall neither be entitled to vote
nor counted for quorum  purposes.  Nothing in this Section shall be construed as
limiting  the right of the  Corporation  to vote its own  stock  held by it in a
fiduciary capacity. At all meetings of the stockholders, a quorum being present,
all matters shall be decided by majority vote of the shares of stock entitled to
vote held by  stockholders  present in person or by proxy,  except as  otherwise
required  by law or the  Certificate  of  Incorporation.  Unless  demanded  by a
stockholder of the  Corporation  present in person or by proxy at any meeting of
the  stockholders and entitled to vote thereat or so directed by the chairman of
the meeting or required by law, the vote thereat on any question  need not be by
written ballot. On a vote by written ballot,  each ballot shall be signed by the
stockholder  voting,  or in his name by his proxy,  if there be such proxy,  and
shall  state the number of shares  voted by him and the number of votes to which
each share is entitled.

               SECTION  8.  PROXIES.  Each  stockholder  entitled  to  vote at a
meeting of  stockholders  or to express  consent to corporate  action in writing
without a meeting  may  authorize  another  person or  persons to act for him by
proxy.  A proxy  acting  for any  stockholder  shall  be  duly  appointed  by an
instrument in writing  subscribed by such  stockholder.  No proxy shall be valid
after the  expiration  of three  years  from the date  thereof  unless the proxy
provides for a longer period.

               SECTION 9. ACTION  WITHOUT A MEETING.  Any action  required to be
taken at any annual or special  meeting of  stockholders or any action which may
be taken at any annual or special meeting of stockholders may be taken without a
meeting,  without  prior  notice  and  without a vote,  if a consent  in writing
setting forth the action so taken shall be signed by the holders of  outstanding
stock  having not less than the minimum  number of votes that would be necessary
to  authorize  or take such action at a meeting at which all shares  entitled to
vote  thereon  were  present  and  voted.  Prompt  notice  of the  taking of the
corporate action without a meeting by less than unanimous  written consent shall
be given to those stockholders who have not consented in writing.


                                   ARTICLE III

                               BOARD OF DIRECTORS

shall be managed under the direction of the Board of Directors.

               SECTION 2.  ELECTION AND TERM.  Except as  otherwise  provided by
law,  Directors shall be elected at the annual meeting of stockholders and shall
hold  office  until the next  annual  meeting of  stockholders  and until  their
successors  are elected  and  qualify,  or until they sooner die,  resign or are
removed.  At each annual meeting of stockholders,  at which a quorum is


                                       4
<PAGE>

present,  the  persons  receiving  a  plurality  of the votes  cast shall be the
Directors.  Acceptance  of the office of Director may be expressed  orally or in
writing,  and  attendance  at the  organization  meeting shall  constitute  such
acceptance.

               SECTION 3. NUMBER.  The number of Directors  shall be such number
as shall be determined from time to time by the Board of Directors and initially
shall be two.

               SECTION 4. QUORUM AND MANNER OF ACTING. Unless otherwise provided
by law, the  presence of 50% of the whole Board of Directors  shall be necessary
to  constitute a quorum for the  transaction  of  business.  In the absence of a
quorum, a majority of the Directors present may adjourn the meeting from time to
time until a quorum shall be present.  Notice of any adjourned  meeting need not
be given.  At all meetings of  Directors,  a quorum being  present,  all matters
shall be decided by the affirmative vote of a majority of the Directors present,
except  as  otherwise  required  by law.  The  Board of  Directors  may hold its
meetings  at such place or places  within or without  the State of Nevada as the
Board of Directors  may from time to time  determine or as shall be specified in
the respective notices, or waivers of notice, thereof.

               SECTION 5.  ORGANIZATION  MEETING.  Immediately after each annual
meeting of  stockholders  for the election of  Directors  the Board of Directors
shall meet at the place of the annual meeting of stockholders for the purpose of
organization,  the election of officers and the  transaction of other  business.
Notice of such meeting  need not be given.  If such meeting is held at any other
time or place, notice thereof must be given as hereinafter  provided for special
meetings of the Board of Directors,  subject to the execution of a waiver of the
notice  thereof  signed by, or the  attendance at such meeting of, all Directors
who may not have received such notice.

               SECTION 6.  REGULAR  MEETINGS.  Regular  meetings of the Board of
Directors may be held at such place,  within or without the State of Nevada,  as
shall from time to time be determined by the Board of Directors. After there has
been such  determination,  and notice thereof has been once given to each member
of the Board of Directors as hereinafter provided for special meetings,  regular
meetings may be held without further notice being given.

               SECTION 7.  SPECIAL  MEETINGS;  NOTICE.  Special  meetings of the
Board of Directors  shall be held whenever  called by the Chairman of the Board,
if any,  the  President or by a majority of the  Directors.  Notice of each such
meeting shall be mailed to each  Director,  addressed to him at his residence or
usual place of business, at least five days before the date on which the meeting
is to be held, or shall be sent to him at such place by telex or  facsimile,  or
be delivered  personally or by telephone,  not later than the day before the day
on which such  meeting is to be held.  Each such notice shall state the time and
place of the meeting and, as may be required,  the purposes  thereof.  Notice of
any meeting of the Board of  Directors  need not be given to any  Director if he
shall  sign a written  waiver  thereof  either  before or after the time  stated
therein  for such  meeting,  or if he shall be  present at the  meeting.  Unless
limited by law, the Certificate of Incorporation,  these By-laws or the terms of
the notice  thereof,  any and all  business  may be  transacted  at any  meeting
without the notice  thereof  having  specifically  identified  the matters to be
acted upon.

of Directors may be removed,  with or without  cause,  at any time, by action of
the holders of record of the majority of the issued and outstanding stock of the
Corporation  (a)  present  in person or by proxy at a meeting of holders of such
stock and  entitled to vote thereon or (b) by a consent in writing in the manner
contemplated  in Section 9 of Article  II, and the vacancy or  vacancies  in the
Board of Directors  caused by any such removal may be filled by action of such a
majority at such meeting or at any subsequent meeting or by consent.

               SECTION 9.  RESIGNATIONS.  Any  Director of the  Corporation  may
resign at any time by giving  written  notice to the  Chairman of the Board,  if
any, the President, the Vice President or the Secretary of the Corporation.  The
resignation  of any Director shall take effect upon receipt of notice thereof or
at such later time as shall be specified in such notice;  and, unless  otherwise
specified therein,  the acceptance of such resignation shall not be necessary to
make it effective.

               SECTION  10.  VACANCIES.  Any  newly  created  directorships  and

of the holders of record of the majority of the issued and outstanding  stock of
the  Corporation  (a)  present  in person or by proxy at a meeting of holders of
such stock and  entitled  to vote  thereon or (b) by a consent in writing in the
manner contemplated in Section 9 of Article II. The Director so chosen,  whether
selected to fill a vacancy or elected to a new  directorship,  shall hold office
until the next meeting of  stockholders at which the election of Directors is in
the regular  order of  business,  and until his  successor  has been elected and
qualifies, or until he sooner dies, resigns or is removed.

               SECTION 11. COMPENSATION OF DIRECTORS.  Directors, as such, shall
not receive any stated  salary for their  services,  but, by  resolution  of the
Board,  a specific  sum fixed by the Board  plus  expenses  may be  allowed  for
attendance at each regular or special meeting of the Board;  PROVIDED,  HOWEVER,
that nothing herein  contained  shall be construed to preclude any Director from
serving the Corporation or any parent or subsidiary  corporation  thereof in any
other capacity and receiving compensation therefor.

               SECTION  12.  ACTION  WITHOUT A MEETING.  Any action  required or
permitted  to be taken at any  meeting  of the Board of  Directors  may be taken
without a meeting if a written  consent  thereto is signed by all members of the
Board,  and such written consent is filed with the minutes or proceedings of the
Board.

               SECTION 13. TELEPHONIC PARTICIPATION IN MEETINGS.  Members of the
Board  of  Directors  may  participate  in a  meeting  of the  Board by means of
conference telephone or similar  communications  equipment by means of which all
persons participating in the meeting can hear each other, and such participation
shall constitute presence in person at such meeting.

form as the Board of Directors shall prescribe,  certifying the number of shares
of the capital stock of the  Corporation  owned by him. No certificate  shall be

countersigned  (1)  by a  transfer  agent  other  than  the  Corporation  or its
employee, or, (2) by a registrar other than the Corporation or its employee, the
signatures of such officers of the  Corporation  may be facsimiles.  In case any
officer of the Corporation who has signed, or whose facsimile signature has been

new  certificate  or  certificates  shall be issued in exchange for any existing
certificate until such existing certificate shall have been so canceled, except,
subject to Section 7 of this  Article VI, in cases  provided  for by  applicable
law.

               SECTION 5. REGISTRATIONS OF TRANSFERS OF STOCK.  Registrations of

of the Corporation shall be deemed the owner thereof for all purposes as regards
the Corporation;  PROVIDED,  HOWEVER, that whenever any transfer of shares shall
be made for collateral security, and not absolutely, it shall be so expressed in
the  entry of the  transfer  if,  when the  certificates  are  presented  to the
Corporation  for transfer,  both the transferor  and the transferee  request the

and registration of certificates for shares of the stock of the Corporation.  It
may appoint,  or authorize any principal officer or officers to appoint,  one or
more transfer clerks or one or more transfer agents and one or more  registrars,
and may require all certificates of stock to bear the signature or signatures of
any of them.

               SECTION 7. LOST,  STOLEN,  DESTROYED OR  MUTILATED  CERTIFICATES.
Before any certificates for stock of the Corporation shall be issued in exchange
for  certificates  which  shall  become  mutilated  or shall be lost,  stolen or
destroyed,  proper evidence of such loss, theft, mutilation or destruction shall
be procured for the Board of Directors, if it so requires.

               SECTION 8.  RECORD  DATES.  For the  purpose of  determining  the
stockholders  entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or entitled to receive payment of any dividend or other
distribution  or allotment of any rights,  or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful  action,  the Board of Directors  may fix, in advance,  a date as a

Shareholder for acts committed in the course of conducting the business of the
Trust, other than acts committed in bad faith, such Trustee, officer, agent or

expenses by reason of such liability. The Trust property shall be applied to

Trustees, then of the officers of the Trust, then of the agents of the Trust,
and then of the Shareholders.

their issue now living, unless sooner terminated as hereinafter provided. In the
case of any such termination, the Trustees shall transfer and convey the entire
Trust estate, subject to any leases, mortgages, contracts, or other encumbrances
thereon, to the holders of the then outstanding Shares of Beneficial Interest
hereunder as tenants in common in proportion to their respective interests, or
as otherwise directed in writing by the holders of at least seventy-five percent
(75%) of the then outstanding Shares of Beneficial Interest hereunder. The
Trustees in office at the time of such termination shall continue in office

express written consent of Shareholders holding at least seventy-five percent
(75%) of the Shares of Beneficial Interest then outstanding.

SECTION 15. MERGER.

the General Laws of Massachusetts, as amended from time to time.

SECTION 16. AMENDMENTS.

         Except as otherwise provided by this Section 16, this Agreement and
Declaration of Trust may be amended at any time by an instrument in writing
signed by the Trustees and approved by Shareholders holding at least

                                   INDEMNITY
                                  -----------

     SECTION 7.1 RIGHT TO INDEMNITY. Every person who was or is a party, or is
threatened to be made party to, or is involved in, any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that such person or a person for whom such
person is the legal representative is or was a director, officer, agent or
employee of another corporation, partnership, joint venture, trust or other
enterprise, shall be indemnified and held harmless to the fullest extent legally
permissible under the laws of the State of Nevada, from time to time existing,
against all expenses, liability and loss (including attorneys' fees, judgments,
fines and amounts paid or to be paid in settlement) reasonably incurred or
suffered by such person in connection therewith. Such right to indemnification
shall be a contract right which may be enforced in any manner desired by such
person. Such right of indemnification shall not be exclusive of any other right
which such director, officer or representative may have or hereafter acquire,
and, without limiting the generality of such statement, such persons shall be
entitled to their respective rights of indemnification under any bylaw,
agreement, vote of stockholders, provision of law, or otherwise, as well as
their rights under this Article VII.

     SECTION 7.2 EXPENSES ADVANCED. Expenses of directors and officers incurred
in defending a civil or criminal action, suit or proceeding by reason of any act
or omission of such director of officer acting as a director or officer shall be
paid by the Corporation as such expenses are incurred and in advance of the
final disposition of the action, suit or


                                      -2-

proceeding, upon receipt of any undertaking by a court of competent jurisdiction
that such person is not entitled to be indemnified by the Corporation.

     SECTION 7.3 BYLAWS AND INSURANCE. Without limiting the application of the
foregoing, the board of directors may adopt bylaws from time to time with
respect to indemnification, to provide at all times the fullest indemnification
permitted by the laws of the State of Nevada, and may cause the Corporation to
purchase and maintain insurance or make other financial arrangements on behalf
of any person who is or was a director, officer, employee or agent of the
Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against any liability asserted against such
person and incurred in any such capacity or arising out of such status, to the
fullest extent permitted by the laws of the State of Nevada, whether or not the
Corporation would have the power to indemnify such person against such liability
and expenses.

     SECTION 7.4 SURVIVAL. The indemnification and advancement of expenses
provided in this Article VII shall continue for a person who has ceased to be a
director, officer, employee or agent, and inures to the benefit of the heirs,
executors and administrators of such a person.

Corporation's business.


                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

               SECTION 1. PLACE OF MEETINGS.  All meetings of stockholders shall
be held at such place or places,  within or without the State of Nevada,  as may
from time to time be fixed by the Board of  Directors,  or as shall be specified
in the respective notices, or waivers of notice, thereof.

               SECTION 2. ANNUAL MEETING. The annual meeting of stockholders for
the election of Directors and the transaction of other business shall be held on

               SECTION  3.   SPECIAL   MEETINGS.   A  special   meeting  of  the
stockholders,  or of any class  thereof  entitled  to vote,  for any  purpose or
purposes, may be called at any time by the Chairman of the Board, if any, or the
President  or by order of the  Board of  Directors  and  shall be  called by the
Secretary upon the written  request of  stockholders  holding of record at least
50% of the outstanding  shares of stock of the  Corporation  entitled to vote at
such meeting. Such written request shall state the purpose or purposes for which
such meeting is to be called.

               SECTION 4. NOTICE OF MEETINGS.  Except as  otherwise  provided by
law, written notice of each meeting of stockholders,  whether annual or special,
stating the place, date and hour of the meeting shall be given not less than ten
days or more than sixty days  before the date on which the meeting is to be held
to each  stockholder  of record  entitled to vote thereat by delivering a notice
thereof  to him  personally  or by  mailing  such  notice in a  postage  prepaid
envelope  directed  to him at his  address as it  appears on the  records of the
Corporation,  unless he shall have filed with the Secretary of the Corporation a
written request that notices intended for him be directed to another address, in
which case such notice  shall be directed  to him at the address  designated  in
such request.  Notice shall not be required to be given to any  stockholder  who
shall waive such notice in writing,  whether prior to or after such meeting,  or
who shall attend such meeting in person or by proxy  unless such  attendance  is
for the express purpose of objecting,  at the beginning of such meeting,  to the
transactions  of any  business  because  the meeting is not  lawfully  called or
convened.  Every notice of a special  meeting of the  stockholders,  besides the
time and place of the  meeting,  shall  state  briefly  the  objects or purposes
thereof.

               SECTION  5.  LIST OF  STOCKHOLDERS.  It  shall be the duty of the
Secretary or other officer of the Corporation who shall have charge of the stock
ledger to  prepare  and make,  at least ten days  before  every  meeting  of the
stockholders,  a complete  list of the  stockholders  entitled to vote  thereat,
arranged in alphabetical  order, and showing the address of each stockholder and
the  number of shares  registered  in his name.  Such list  shall be open to the
examination of any stockholder,  for any purpose germane to the meeting,  during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place  within the city where the meeting is to be held,  which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place  where the meeting is to be held.  The list shall be kept and  produced at
the time and place of the meeting  during the whole time  thereof and subject to
the inspection of any stockholder who may be present.  The original or duplicate
ledger  shall be the only  evidence as to who are the  stockholders  entitled to
examine  such  list or the books of the  Corporation  or to vote in person or by
proxy at such meeting.

               SECTION  6.  QUORUM.  At each  meeting of the  stockholders,  the
holders of record of a  majority  of the  issued  and  outstanding  stock of the
Corporation  entitled  to vote at such  meeting,  present in person or by proxy,
shall  constitute  a  quorum  for the  transaction  of  business,  except  where
otherwise provided by law, the Certificate of Incorporation or these By-laws. In
the absence of a quorum, any officer entitled to preside at, or act as Secretary
of, such  meeting  shall have the power to adjourn the meeting from time to time
until a quorum shall be constituted.

               SECTION 7. VOTING. Every stockholder of record who is entitled to
vote shall at every meeting of the stockholders be entitled to one vote for each
share of stock held by him on the record date; EXCEPT,  HOWEVER,  that shares of
its own stock  belonging  to the  Corporation  or to another  corporation,  if a
majority of the shares  entitled to vote in the  election of  directors  of such
other corporation is held by the Corporation,  shall neither be entitled to vote
nor counted for quorum  purposes.  Nothing in this Section shall be construed as
limiting  the right of the  Corporation  to vote its own  stock  held by it in a
fiduciary capacity. At all meetings of the stockholders, a quorum being present,
all matters shall be decided by majority vote of the shares of stock entitled to
vote held by  stockholders  present in person or by proxy,  except as  otherwise
required  by law or the  Certificate  of  Incorporation.  Unless  demanded  by a
stockholder of the  Corporation  present in person or by proxy at any meeting of
the  stockholders and entitled to vote thereat or so directed by the chairman of
the meeting or required by law, the vote thereat on any question  need not be by
written ballot. On a vote by written ballot,  each ballot shall be signed by the
stockholder  voting,  or in his name by his proxy,  if there be such proxy,  and
shall  state the number of shares  voted by him and the number of votes to which
each share is entitled.

               SECTION  8.  PROXIES.  Each  stockholder  entitled  to  vote at a
meeting of  stockholders  or to express  consent to corporate  action in writing
without a meeting  may  authorize  another  person or  persons to act for him by
proxy.  A proxy  acting  for any  stockholder  shall  be  duly  appointed  by an
instrument in writing  subscribed by such  stockholder.  No proxy shall be valid
after the  expiration  of three  years  from the date  thereof  unless the proxy
provides for a longer period.

               SECTION 9. ACTION  WITHOUT A MEETING.  Any action  required to be
taken at any annual or special  meeting of  stockholders or any action which may
be taken at any annual or special meeting of stockholders may be taken without a
meeting,  without  prior  notice  and  without a vote,  if a consent  in writing
setting forth the action so taken shall be signed by the holders of  outstanding
stock  having not less than the minimum  number of votes that would be necessary
to  authorize  or take such action at a meeting at which all shares  entitled to
vote  thereon  were  present  and  voted.  Prompt  notice  of the  taking of the
corporate action without a meeting by less than unanimous  written consent shall
be given to those stockholders who have not consented in writing.


                                   ARTICLE III

shall be managed under the direction of the Board of Directors.

               SECTION 2.  ELECTION AND TERM.  Except as  otherwise  provided by
law,  Directors shall be elected at the annual meeting of stockholders and shall
hold  office  until the next  annual  meeting of  stockholders  and until  their
successors  are elected  and  qualify,  or until they sooner die,  resign or are
removed.  At each annual meeting of stockholders,  at which a quorum is




                                       4
<PAGE>

present,  the  persons  receiving  a  plurality  of the votes  cast shall be the
Directors.  Acceptance  of the office of Director may be expressed  orally or in
writing,  and  attendance  at the  organization  meeting shall  constitute  such
acceptance.

               SECTION 3. NUMBER.  The number of Directors  shall be such number
as shall be determined from time to time by the Board of Directors and initially
shall be two.

               SECTION 4. QUORUM AND MANNER OF ACTING. Unless otherwise provided
by law, the  presence of 50% of the whole Board of Directors  shall be necessary
to  constitute a quorum for the  transaction  of  business.  In the absence of a
quorum, a majority of the Directors present may adjourn the meeting from time to
time until a quorum shall be present.  Notice of any adjourned  meeting need not
be given.  At all meetings of  Directors,  a quorum being  present,  all matters
shall be decided by the affirmative vote of a majority of the Directors present,
except  as  otherwise  required  by law.  The  Board of  Directors  may hold its
meetings  at such place or places  within or without  the State of Nevada as the
Board of Directors  may from time to time  determine or as shall be specified in
the respective notices, or waivers of notice, thereof.

               SECTION 5.  ORGANIZATION  MEETING.  Immediately after each annual
meeting of  stockholders  for the election of  Directors  the Board of Directors
shall meet at the place of the annual meeting of stockholders for the purpose of
organization,  the election of officers and the  transaction of other  business.
Notice of such meeting  need not be given.  If such meeting is held at any other
time or place, notice thereof must be given as hereinafter  provided for special
meetings of the Board of Directors,  subject to the execution of a waiver of the
notice  thereof  signed by, or the  attendance at such meeting of, all Directors
who may not have received such notice.

               SECTION 6.  REGULAR  MEETINGS.  Regular  meetings of the Board of
Directors may be held at such place,  within or without the State of Nevada,  as
shall from time to time be determined by the Board of Directors. After there has
been such  determination,  and notice thereof has been once given to each member
of the Board of Directors as hereinafter provided for special meetings,  regular
meetings may be held without further notice being given.

               SECTION 7.  SPECIAL  MEETINGS;  NOTICE.  Special  meetings of the
Board of Directors  shall be held whenever  called by the Chairman of the Board,
if any,  the  President or by a majority of the  Directors.  Notice of each such
meeting shall be mailed to each  Director,  addressed to him at his residence or
usual place of business, at least five days before the date on which the meeting
is to be held, or shall be sent to him at such place by telex or  facsimile,  or
be delivered  personally or by telephone,  not later than the day before the day
on which such  meeting is to be held.  Each such notice shall state the time and
place of the meeting and, as may be required,  the purposes  thereof.  Notice of
any meeting of the Board of  Directors  need not be given to any  Director if he
shall  sign a written  waiver  thereof  either  before or after the time  stated
therein  for such  meeting,  or if he shall be  present at the  meeting.  Unless
limited by law, the Certificate of Incorporation,  these By-laws or the terms of
the notice  thereof,  any and all  business  may be  transacted  at any  meeting
without the notice  thereof  having  specifically  identified  the matters to be
acted upon.

of Directors may be removed,  with or without  cause,  at any time, by action of
the holders of record of the majority of the issued and outstanding stock of the
Corporation  (a)  present  in person or by proxy at a meeting of holders of such
stock and  entitled to vote thereon or (b) by a consent in writing in the manner
contemplated  in Section 9 of Article  II, and the vacancy or  vacancies  in the
Board of Directors  caused by any such removal may be filled by action of such a
majority at such meeting or at any subsequent meeting or by consent.

               SECTION 9.  RESIGNATIONS.  Any  Director of the  Corporation  may
resign at any time by giving  written  notice to the  Chairman of the Board,  if
any, the President, the Vice President or the Secretary of the Corporation.  The
resignation  of any Director shall take effect upon receipt of notice thereof or
at such later time as shall be specified in such notice;  and, unless  otherwise
specified therein,  the acceptance of such resignation shall not be necessary to
make it effective.

               SECTION  10.  VACANCIES.  Any  newly  created  directorships  and
vacancies  occurring in the Board by reason of death,  resignation,  retirement,
disqualification or removal,  with or without cause, may be filled by the action
of the holders of record of the majority of the issued and outstanding  stock of
the  Corporation  (a)  present  in person or by proxy at a meeting of holders of
such stock and  entitled  to vote  thereon or (b) by a consent in writing in the
manner contemplated in Section 9 of Article II. The Director so chosen,  whether
selected to fill a vacancy or elected to a new  directorship,  shall hold office
until the next meeting of  stockholders at which the election of Directors is in
the regular  order of  business,  and until his  successor  has been elected and
qualifies, or until he sooner dies, resigns or is removed.

               SECTION 11. COMPENSATION OF DIRECTORS.  Directors, as such, shall
not receive any stated  salary for their  services,  but, by  resolution  of the
Board,  a specific  sum fixed by the Board  plus  expenses  may be  allowed  for
attendance at each regular or special meeting of the Board;  PROVIDED,  HOWEVER,
that nothing herein  contained  shall be construed to preclude any Director from
serving the Corporation or any parent or subsidiary  corporation  thereof in any
other capacity and receiving compensation therefor.

               SECTION  12.  ACTION  WITHOUT A MEETING.  Any action  required or
permitted  to be taken at any  meeting  of the Board of  Directors  may be taken
without a meeting if a written  consent  thereto is signed by all members of the
Board,  and such written consent is filed with the minutes or proceedings of the
Board.

               SECTION 13. TELEPHONIC PARTICIPATION IN MEETINGS.  Members of the
Board  of  Directors  may  participate  in a  meeting  of the  Board by means of
conference telephone or similar  communications  equipment by means of which all
persons participating in the meeting can hear each other, and such participation
shall constitute presence in person at such meeting.

with and to the  fullest  extent  permitted  by law for the  defense  of,  or in
connection  with,  any  threatened,   pending  or  completed  action,   suit  or
proceeding, whether civil, criminal, administrative or investigative.

               SECTION 2.  EXPENSES.  Expenses  incurred in defending a civil or
criminal action, suit or proceeding may be paid by the Corporation in advance of
the final  disposition  of such action,  suit or proceeding as authorized by the

Corporation as authorized in this Article V.

               SECTION  3.  OTHER  RIGHTS  OF  INDEMNIFICATION.   The  right  of

rights to which any such  Director or officer may now or  hereafter  be entitled

                            SHARES AND THEIR TRANSFER

               SECTION  1.  CERTIFICATE  FOR  STOCK.  Every  stockholder  of the
Corporation  shall be entitled to a certificate or  certificates,  to be in such
form as the Board of Directors shall prescribe,  certifying the number of shares
of the capital stock of the  Corporation  owned by him. No certificate  shall be
issued for partly paid shares.

               SECTION 2. STOCK CERTIFICATE SIGNATURE. The certificates for such
stock  shall be numbered in the order in which they shall be issued and shall be
signed by the  Chairman  of the  Board,  if any,  or the  President  or any Vice
President and by the Secretary or an Assistant Secretary or the Treasurer of the
Corporation,  and its seal  shall be affixed  thereto.  If such  certificate  is
countersigned  (1)  by a  transfer  agent  other  than  the  Corporation  or its
employee, or, (2) by a registrar other than the Corporation or its employee, the
signatures of such officers of the  Corporation  may be facsimiles.  In case any
officer of the Corporation who has signed, or whose facsimile signature has been
placed upon,  any such  certificate  shall have ceased to be such officer before
such  certificate is issued,  it may be issued by the Corporation  with the same
effect as if he were such officer at the date of issue.

               SECTION 3. STOCK LEDGER.  A record shall be kept by the Secretary
or by any other officer,  employee or agent designated by the Board of Directors
of the name of each person,  firm or  corporation  holding  capital stock of the
Corporation,  the number of shares  represented by, and the respective dates of,
each certificate for such capital stock, and in case of cancellation of any such
certificate, the respective dates of cancellation.

Corporation for exchange or  registration of transfer shall be canceled,  and no
new  certificate  or  certificates  shall be issued in exchange for any existing
certificate until such existing certificate shall have been so canceled, except,
subject to Section 7 of this  Article VI, in cases  provided  for by  applicable
law.

               SECTION 5. REGISTRATIONS OF TRANSFERS OF STOCK.  Registrations of
transfers of shares of the capital stock of the Corporation shall be made on the
books of the Corporation by the registered  holder  thereof,  or by his attorney
thereunto  authorized  by power of  attorney  duly  executed  and filed with the
Secretary  of the  Corporation  or with a  transfer  clerk or a  transfer  agent
appointed as in Section 6 of this  Article VI provided,  and on surrender of the
certificate or certificates for such shares properly endorsed and the payment of
all taxes  thereon.  The person in whose name shares of stock stand on the books
of the Corporation shall be deemed the owner thereof for all purposes as regards
the Corporation;  PROVIDED,  HOWEVER, that whenever any transfer of shares shall
be made for collateral security, and not absolutely, it shall be so expressed in
the  entry of the  transfer  if,  when the  certificates  are  presented  to the
Corporation  for transfer,  both the transferor  and the transferee  request the
Corporation to do so.

               SECTION  6.  REGULATIONS.  The Board of  Directors  may make such
rules  and  regulations  as it may deem  expedient,  not  inconsistent  with the
Certificate of Incorporation or these By- laws,  concerning the issue,  transfer
and registration of certificates for shares of the stock of the Corporation.  It
may appoint,  or authorize any principal officer or officers to appoint,  one or
more transfer clerks or one or more transfer agents and one or more  registrars,
and may require all certificates of stock to bear the signature or signatures of
any of them.

               SECTION 7. LOST,  STOLEN,  DESTROYED OR  MUTILATED  CERTIFICATES.
Before any certificates for stock of the Corporation shall be issued in exchange
for  certificates  which  shall  become  mutilated  or shall be lost,  stolen or
destroyed,  proper evidence of such loss, theft, mutilation or destruction shall
be procured for the Board of Directors, if it so requires.

               SECTION 8.  RECORD  DATES.  For the  purpose of  determining  the
stockholders  entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or entitled to receive payment of any dividend or other
distribution  or allotment of any rights,  or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful  action,  the Board of Directors  may fix, in advance,  a date as a
record date for any such  determination of stockholders.  Such record date shall
not be more than sixty or less than ten days before the date of such meeting, or

Certificate of  Incorporation,  the Board of Directors may, out of funds legally
available therefor, at any regular or special meeting declare dividends upon the
capital  stock  of the  Corporation  as and when  they  deem  expedient.  Before
declaring  any  dividend  there  may  be set  apart  out  of  any  funds  of the
Corporation  available for dividends such sum or sums as the Directors from time
to time in their discretion deem proper for working capital or as a reserve fund
to meet contingencies or for equalizing  dividends or for such other purposes as
the Board of Directors shall deem conducive to the interests of the Corporation.

Corporation's business.


                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

               SECTION 1. PLACE OF MEETINGS.  All meetings of stockholders shall
be held at such place or places,  within or without the State of Nevada,  as may
from time to time be fixed by the Board of  Directors,  or as shall be specified
in the respective notices, or waivers of notice, thereof.

               SECTION 2. ANNUAL MEETING. The annual meeting of stockholders for
the election of Directors and the transaction of other business shall be held on

<PAGE>

               SECTION  3.   SPECIAL   MEETINGS.   A  special   meeting  of  the
stockholders,  or of any class  thereof  entitled  to vote,  for any  purpose or
purposes, may be called at any time by the Chairman of the Board, if any, or the
President  or by order of the  Board of  Directors  and  shall be  called by the
Secretary upon the written  request of  stockholders  holding of record at least
50% of the outstanding  shares of stock of the  Corporation  entitled to vote at
such meeting. Such written request shall state the purpose or purposes for which
such meeting is to be called.

               SECTION 4. NOTICE OF MEETINGS.  Except as  otherwise  provided by
law, written notice of each meeting of stockholders,  whether annual or special,
stating the place, date and hour of the meeting shall be given not less than ten

to each  stockholder  of record  entitled to vote thereat by delivering a notice
thereof  to him  personally  or by  mailing  such  notice in a  postage  prepaid
envelope  directed  to him at his  address as it  appears on the  records of the
Corporation,  unless he shall have filed with the Secretary of the Corporation a
written request that notices intended for him be directed to another address, in
which case such notice  shall be directed  to him at the address  designated  in
such request.  Notice shall not be required to be given to any  stockholder  who
shall waive such notice in writing,  whether prior to or after such meeting,  or
who shall attend such meeting in person or by proxy  unless such  attendance  is
for the express purpose of objecting,  at the beginning of such meeting,  to the
transactions  of any  business  because  the meeting is not  lawfully  called or
convened.  Every notice of a special  meeting of the  stockholders,  besides the
time and place of the  meeting,  shall  state  briefly  the  objects or purposes
thereof.

               SECTION  5.  LIST OF  STOCKHOLDERS.  It  shall be the duty of the
Secretary or other officer of the Corporation who shall have charge of the stock
ledger to  prepare  and make,  at least ten days  before  every  meeting  of the
stockholders,  a complete  list of the  stockholders  entitled to vote  thereat,
arranged in alphabetical  order, and showing the address of each stockholder and
the  number of shares  registered  in his name.  Such list  shall be open to the
examination of any stockholder,  for any purpose germane to the meeting,  during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place  within the city where the meeting is to be held,  which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place  where the meeting is to be held.  The list shall be kept and  produced at
the time and place of the meeting  during the whole time  thereof and subject to
the inspection of any stockholder who may be present.  The original or duplicate
ledger  shall be the only  evidence as to who are the  stockholders  entitled to
examine  such  list or the books of the  Corporation  or to vote in person or by
proxy at such meeting.

               SECTION  6.  QUORUM.  At each  meeting of the  stockholders,  the
holders of record of a  majority  of the  issued  and  outstanding  stock of the
Corporation  entitled  to vote at such  meeting,  present in person or by proxy,
shall  constitute  a  quorum  for the  transaction  of  business,  except  where
otherwise provided by law, the Certificate of Incorporation or these By-laws. In
the absence of a quorum, any officer entitled to preside at, or act as Secretary
of, such  meeting  shall have the power to adjourn the meeting from time to time
until a quorum shall be constituted.

<PAGE>

               SECTION 7. VOTING. Every stockholder of record who is entitled to
vote shall at every meeting of the stockholders be entitled to one vote for each
share of stock held by him on the record date; EXCEPT,  HOWEVER,  that shares of
its own stock  belonging  to the  Corporation  or to another  corporation,  if a
majority of the shares  entitled to vote in the  election of  directors  of such
other corporation is held by the Corporation,  shall neither be entitled to vote
nor counted for quorum  purposes.  Nothing in this Section shall be construed as
limiting  the right of the  Corporation  to vote its own  stock  held by it in a
fiduciary capacity. At all meetings of the stockholders, a quorum being present,
all matters shall be decided by majority vote of the shares of stock entitled to
vote held by  stockholders  present in person or by proxy,  except as  otherwise
required  by law or the  Certificate  of  Incorporation.  Unless  demanded  by a
stockholder of the  Corporation  present in person or by proxy at any meeting of
the  stockholders and entitled to vote thereat or so directed by the chairman of
the meeting or required by law, the vote thereat on any question  need not be by
written ballot. On a vote by written ballot,  each ballot shall be signed by the
stockholder  voting,  or in his name by his proxy,  if there be such proxy,  and
shall  state the number of shares  voted by him and the number of votes to which
each share is entitled.

               SECTION  8.  PROXIES.  Each  stockholder  entitled  to  vote at a
meeting of  stockholders  or to express  consent to corporate  action in writing
without a meeting  may  authorize  another  person or  persons to act for him by
proxy.  A proxy  acting  for any  stockholder  shall  be  duly  appointed  by an
instrument in writing  subscribed by such  stockholder.  No proxy shall be valid
after the  expiration  of three  years  from the date  thereof  unless the proxy
provides for a longer period.

               SECTION 9. ACTION  WITHOUT A MEETING.  Any action  required to be
taken at any annual or special  meeting of  stockholders or any action which may
be taken at any annual or special meeting of stockholders may be taken without a
meeting,  without  prior  notice  and  without a vote,  if a consent  in writing
setting forth the action so taken shall be signed by the holders of  outstanding
stock  having not less than the minimum  number of votes that would be necessary
to  authorize  or take such action at a meeting at which all shares  entitled to
vote  thereon  were  present  and  voted.  Prompt  notice  of the  taking of the
corporate action without a meeting by less than unanimous  written consent shall

present,  the  persons  receiving  a  plurality  of the votes  cast shall be the
Directors.  Acceptance  of the office of Director may be expressed  orally or in
writing,  and  attendance  at the  organization  meeting shall  constitute  such
acceptance.

               SECTION 3. NUMBER.  The number of Directors  shall be such number
as shall be determined from time to time by the Board of Directors and initially

               SECTION 4. QUORUM AND MANNER OF ACTING. Unless otherwise provided
by law, the  presence of 50% of the whole Board of Directors  shall be necessary
to  constitute a quorum for the  transaction  of  business.  In the absence of a
quorum, a majority of the Directors present may adjourn the meeting from time to
time until a quorum shall be present.  Notice of any adjourned  meeting need not
be given.  At all meetings of  Directors,  a quorum being  present,  all matters
shall be decided by the affirmative vote of a majority of the Directors present,
except  as  otherwise  required  by law.  The  Board of  Directors  may hold its
meetings  at such place or places  within or without  the State of Nevada as the
Board of Directors  may from time to time  determine or as shall be specified in
the respective notices, or waivers of notice, thereof.

               SECTION 5.  ORGANIZATION  MEETING.  Immediately after each annual
meeting of  stockholders  for the election of  Directors  the Board of Directors
shall meet at the place of the annual meeting of stockholders for the purpose of
organization,  the election of officers and the  transaction of other  business.
Notice of such meeting  need not be given.  If such meeting is held at any other
time or place, notice thereof must be given as hereinafter  provided for special
meetings of the Board of Directors,  subject to the execution of a waiver of the
notice  thereof  signed by, or the  attendance at such meeting of, all Directors
who may not have received such notice.

Directors may be held at such place,  within or without the State of Nevada,  as
shall from time to time be determined by the Board of Directors. After there has

of the Board of Directors as hereinafter provided for special meetings,  regular
meetings may be held without further notice being given.

               SECTION 7.  SPECIAL  MEETINGS;  NOTICE.  Special  meetings of the

any meeting of the Board of  Directors  need not be given to any  Director if he
shall  sign a written  waiver  thereof  either  before or after the time  stated
therein  for such  meeting,  or if he shall be  present at the  meeting.  Unless
limited by law, the Certificate of Incorporation,  these By-laws or the terms of

without the notice  thereof  having  specifically  identified  the matters to be
acted upon.

Corporation  (a)  present  in person or by proxy at a meeting of holders of such
stock and  entitled to vote thereon or (b) by a consent in writing in the manner
contemplated  in Section 9 of Article  II, and the vacancy or  vacancies  in the

the  Corporation  (a)  present  in person or by proxy at a meeting of holders of
such stock and  entitled  to vote  thereon or (b) by a consent in writing in the
manner contemplated in Section 9 of Article II. The Director so chosen,  whether
selected to fill a vacancy or elected to a new  directorship,  shall hold office
until the next meeting of  stockholders at which the election of Directors is in
the regular  order of  business,  and until his  successor  has been elected and
qualifies, or until he sooner dies, resigns or is removed.

               SECTION 11. COMPENSATION OF DIRECTORS.  Directors, as such, shall
not receive any stated  salary for their  services,  but, by  resolution  of the
Board,  a specific  sum fixed by the Board  plus  expenses  may be  allowed  for
attendance at each regular or special meeting of the Board;  PROVIDED,  HOWEVER,
that nothing herein  contained  shall be construed to preclude any Director from
serving the Corporation or any parent or subsidiary  corporation  thereof in any
other capacity and receiving compensation therefor.

               SECTION  12.  ACTION  WITHOUT A MEETING.  Any action  required or
permitted  to be taken at any  meeting  of the Board of  Directors  may be taken
without a meeting if a written  consent  thereto is signed by all members of the
Board,  and such written consent is filed with the minutes or proceedings of the
Board.

               SECTION 13. TELEPHONIC PARTICIPATION IN MEETINGS.  Members of the
Board  of  Directors  may  participate  in a  meeting  of the  Board by means of
conference telephone or similar  communications  equipment by means of which all

               SECTION  1.  CERTIFICATE  FOR  STOCK.  Every  stockholder  of the
Corporation  shall be entitled to a certificate or  certificates,  to be in such
form as the Board of Directors shall prescribe,  certifying the number of shares
of the capital stock of the  Corporation  owned by him. No certificate  shall be

countersigned  (1)  by a  transfer  agent  other  than  the  Corporation  or its
employee, or, (2) by a registrar other than the Corporation or its employee, the
signatures of such officers of the  Corporation  may be facsimiles.  In case any
officer of the Corporation who has signed, or whose facsimile signature has been

effect as if he were such officer at the date of issue.

new  certificate  or  certificates  shall be issued in exchange for any existing
certificate until such existing certificate shall have been so canceled, except,
subject to Section 7 of this  Article VI, in cases  provided  for by  applicable
law.

               SECTION 5. REGISTRATIONS OF TRANSFERS OF STOCK.  Registrations of
transfers of shares of the capital stock of the Corporation shall be made on the
books of the Corporation by the registered  holder  thereof,  or by his attorney

Secretary  of the  Corporation  or with a  transfer  clerk or a  transfer  agent
appointed as in Section 6 of this  Article VI provided,  and on surrender of the
certificate or certificates for such shares properly endorsed and the payment of
all taxes  thereon.  The person in whose name shares of stock stand on the books
of the Corporation shall be deemed the owner thereof for all purposes as regards
the Corporation;  PROVIDED,  HOWEVER, that whenever any transfer of shares shall
be made for collateral security, and not absolutely, it shall be so expressed in
the  entry of the  transfer  if,  when the  certificates  are  presented  to the
Corporation  for transfer,  both the transferor  and the transferee  request the
Corporation to do so.

               SECTION  6.  REGULATIONS.  The Board of  Directors  may make such
rules  and  regulations  as it may deem  expedient,  not  inconsistent  with the
Certificate of Incorporation or these By- laws,  concerning the issue,  transfer
and registration of certificates for shares of the stock of the Corporation.  It
may appoint,  or authorize any principal officer or officers to appoint,  one or
more transfer clerks or one or more transfer agents and one or more  registrars,
and may require all certificates of stock to bear the signature or signatures of
any of them.

               SECTION 7. LOST,  STOLEN,  DESTROYED OR  MUTILATED  CERTIFICATES.
Before any certificates for stock of the Corporation shall be issued in exchange
for  certificates  which  shall  become  mutilated  or shall be lost,  stolen or
destroyed,  proper evidence of such loss, theft, mutilation or destruction shall
be procured for the Board of Directors, if it so requires.

               SECTION 8.  RECORD  DATES.  For the  purpose of  determining  the
stockholders  entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or entitled to receive payment of any dividend or other
distribution  or allotment of any rights,  or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful  action,  the Board of Directors  may fix, in advance,  a date as a
record date for any such  determination of stockholders.  Such record date shall
not be more than sixty or less than ten days before the date of such meeting, or

               SECTION  3.   DIVIDENDS.   Subject  to  the   provisions  of  the
Certificate of  Incorporation,  the Board of Directors may, out of funds legally
available therefor, at any regular or special meeting declare dividends upon the
capital  stock  of the  Corporation  as and when  they  deem  expedient.  Before
declaring  any  dividend  there  may  be set  apart  out  of  any  funds  of the
Corporation  available for dividends such sum or sums as the Directors from time
to time in their discretion deem proper for working capital or as a reserve fund
to meet contingencies or for equalizing  dividends or for such other purposes as
the Board of Directors shall deem conducive to the interests of the Corporation.

                           obtained at the time from Persons who are not
                           Affiliates of the Company;

Unrestricted Subsidiary shall be evidenced to the Trustee by filing with the
Trustee a certified copy of the Board Resolution giving effect to such
designation and an Officers' Certificate certifying that such designation

PROVIDED THAT such designation shall be deemed to be an incurrence of
Indebtedness by a Restricted Subsidiary of the Company of any outstanding
Indebtedness of such Unrestricted Subsidiary and such designation shall be
permitted only if: (1) such Indebtedness is permitted under Section 1008, and

                                      -41-
<PAGE>

                  Upon any application or request by the Company to the Trustee
to take any action under any provision of this Indenture, the Company shall
furnish to the Trustee such certificates and opinions as it may reasonably
request or as may be required under the Trust Indenture Act. Each such
certificate or opinion shall be given in the form of an Officers' Certificate,
if to be given by an officer of the Company, or an Opinion of Counsel, if to be
given by counsel, and shall comply with the requirements of the Trust Indenture
Act and any other requirement set forth in this Indenture.

                  Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

                  (1) a statement that each individual signing such certificate
         or opinion has read such covenant or condition and the definitions

SECTION 103.      FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

                  In any case where several matters are required to be certified
by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

                  Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

                  Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.

SECTION 104.      ACTS OF HOLDERS; RECORD DATE.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

                  (c) The ownership of Notes shall be proved by the Notes
Register.

                  (d) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Note shall bind every future
Holder of the same Note and the Holder of every Note issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reli-

                                      -44-
<PAGE>

ance thereon, whether or not notation of such action is made upon such Note.

                  (e) The Company may set any day as a record day for the
purpose of determining the Holders of Outstanding Notes entitled to give, make
or take any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given, made or
taken by Holders, PROVIDED THAT the Company may not set a record date for, and
the provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in the next
paragraph. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Notes on such record date, and no other Holders, shall be entitled
to take the relevant action, whether or not such Holders remain Holders after
such record date; PROVIDED THAT no such action shall be effective hereunder
unless taken on or prior to the applicable Expiration Date by Holders of the
requisite principal amount of Outstanding Notes on such record date. Nothing in
this paragraph shall be construed to prevent the Company from setting a record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Notes on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder in the manner set forth in Section 106.

                  The Trustee may set any day as a record date for the purpose
of determining the Holders of Outstanding Notes entitled to join in the giving
or making of (i) any Notice of Default, (ii) any declaration of acceleration
referred to in Section 502, (iii) any request to institute proceedings referred
to in Section 507(2) or (iv) any direction referred to in Section 512. If any
record date is set pursuant to this paragraph, the Holders of Outstanding Notes
on such record date, and no other Holders, shall be entitled to join in such
notice, declaration, request or direction, whether or not such Holders remain
Holders after such record date; PROVIDED THAT no such action shall be effective
hereunder

                                      -45-
<PAGE>

unless taken on or prior to the applicable Expiration Date by Holders of the
requisite principal amount of Outstanding Notes on such record date. Nothing in
this paragraph shall be construed to prevent the Trustee from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding Notes
on the date such action is taken. Promptly after any record date is set pursuant
to this paragraph, the Trustee, at the Company's expense, shall cause notice of
such record date, the proposed action by Holders and the applicable Expiration
Date to be given to the Company in writing and to each Holder in the manner set
forth in Section 106.

                  With respect to any record date set pursuant to this Section,
the party hereto which sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; PROVIDED THAT no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder in the manner set forth in Section 106, on or prior
to the existing Expiration Date. If an Expiration Date is not designated with
respect to any record date set pursuant to this Section, the party hereto which
set such record date shall be deemed to have initially designated the 180th day
after such record date as the Expiration Date with respect thereto, subject to
its right to change the Expiration Date as provided in this paragraph.

                  (f) Without limiting the foregoing, a Holder entitled
hereunder to take any action hereunder with regard to any particular Note may do
so with regard to all or any part of the principal amount of such Note or by one
or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such principal amount.

                  (g) Notwithstanding any provision herein to the contrary, all
Notes issued under this Indenture shall vote and consent together on all matters
(as to which the Holders may vote or consent) as one class and no series of
Notes

                                      -46-
<PAGE>

will have the right to vote or consent as a separate class on any matter.

SECTION 105.      NOTICES, ETC., TO TRUSTEE AND COMPANY.

                  Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office
         at United States Trust Company of New York, 114 West 47th Street, New
         York, New York 10036-1532, Attention: Corporate Trust Administration,
         or

                  (2) the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Company addressed to it at the address of its principal
         office specified in the first paragraph of this instrument or at any
         other address previously furnished in writing to the Trustee by the
         Company.

                  Notice to the Trustee shall not be effective until it is
actually received.

SECTION 106.      NOTICE TO HOLDERS; WAIVER.

                  Where this Indenture provides for notice to Holders of any
event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each Holder affected by such event, at his address as it appears in the Note
Register, not later than the latest date (if any), and not earlier than the
earliest date (if any), prescribed for the giving of such notice. In any case
where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders. Where this
Indenture provides for notice in any manner, such notice may be waived in
writing by the Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice. Waivers of
notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such
waiver.

                  In case by reason of the suspension of regular mail service or
by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

SECTION 107.      CONFLICT WITH TRUST INDENTURE ACT.

                  If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be part
of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.

shall bind its successors and assigns, whether so expressed or not.

SECTION 110.      SEPARABILITY CLAUSE.

                  In case any provision in this Indenture or in the Notes shall
be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired
thereby.

SECTION 111.      BENEFITS OF INDENTURE.

                  Nothing in this Indenture or in the Notes, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder and the Holders, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

SECTION 112.      GOVERNING LAW.

                  THIS INDENTURE, THE NOTES AND THE SUBSIDIARY GUARANTEES SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
YORK WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES THERETO.

                  In any case where any Interest Payment Date, Redemption Date,
Purchase Date or Stated Maturity of any Note shall not be a Business Day, then

(notwithstanding any other provision of this Indenture or of the Notes) payment
of interest or principal (and premium, if any) need not be made on such date,
but may be made on the next succeeding Business Day with the same force and
effect as if made on the Interest Payment Date, Redemption Date or Purchase
Date, or at the Stated Maturity, PROVIDED THAT to the extent such payment is
made on such next succeeding Business Day, no interest shall accrue for the
period from and after such Interest Payment Date, Redemption Date, Purchase Date
or Stated Maturity, as the case may be.

SECTION 114.      NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND
                  STOCKHOLDERS.

                  No director, officer, employee, incorporator or stockholder of
the Company or any Guarantor, as such, shall have any liability for any
obligations of the Company or the Guarantors under the Notes, the Subsidiary
Guarantees, this Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder by accepting a Note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes.

U.S. Person (as defined in Regulation S) or has purchased such interest in a
transaction that is exempt from the registration requirements under the
Securities Act (the "Regulation S Certificate"), and Euroclear or CEDEL, as the
case may be, must provide to the Trustee (or to the Paying Agent if other than
the Trustee) a certificate in the form set forth in Exhibit B prior to (i) the
payment of interest or principal with respect to such holder of beneficial

                           (ii) Except as permitted by the following paragraphs
         (iii), (iv) and (v), each Regulation S Temporary Global Note (and all

         statement under the Securities Act:

                                    (A) in the case of any Transfer Restricted
                  Note, the Note Registrar shall permit the Holder thereof to

                                    (B) any such Transfer Restricted Note
                  represented by a Global Note shall not be subject to the
                  provisions set forth in (i), (ii) or (iii) above (such sales
                  or transfers being subject only to the provisions of Section
                  305(c) hereof); PROVIDED, HOWEVER, that with respect to any
                  request for an exchange of a Transfer Restricted Note that is
                  represented by a Global Note for a Definitive Note that does
                  not bear a legend, which request is made in reliance upon Rule
                  144, the Holder thereof shall certify in writing to the Note
                  Registrar that such request is being made pursuant to Rule 144
                  (such certification to be in substantially the form set forth

Exchange Offer shall not bear the legend set forth in (i), (ii) or (iii) above
and the Trustee shall rescind any restriction on the transfer of such Exchange

                  (h) CANCELLATION AND/OR ADJUSTMENT OF GLOBAL NOTE. At such
time as all beneficial interests in a Global Note have either been exchanged for
Definitive Notes or beneficial interests in other Global Notes, redeemed,
repurchased or canceled, such Global Note shall be returned to or retained and
canceled by the Trustee. At any time prior to such cancellation, if any
beneficial interest in a Global Note is exchanged for Definitive Notes or a
beneficial interest in another Global Note, redeemed, repurchased or canceled,
the principal amount of Notes represented by such Global Note shall be reduced
and an endorsement shall be made on such Global Note, by the Trustee or the
Notes Custodian, at the direction of the Trustee, to reflect such reduction.

                  (i) OBLIGATIONS WITH RESPECT TO TRANSFERS AND EXCHANGES OF
DEFINITIVE NOTES. To permit registrations of transfers and exchanges, the
Company shall execute and the Trustee shall authenticate Definitive Notes and
Global Notes at the Note Registrar's request.

                  (j) GENERAL. No service charge shall be made for any
registration of transfer or exchange of Notes, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any registration of transfer or exchange of

                                      -65-
<PAGE>

Notes, other than exchanges pursuant to Section 304, 906 or 1108 or in
accordance with any Asset Sale Offer or Change of Control Offer pursuant to
Section 1015 or 1014, respectively, not involving any transfer.

                  The Company shall not be required (i) to issue, register the
transfer of or exchange any Note during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Notes selected for redemption under Section 1104 and ending at the close of
business on the day of such mailing, or (ii) to register the transfer of or
exchange any Note so selected for redemption in whole or in part, except the
unredeemed portion of any Note being redeemed in part.

SECTION 306.      MUTILATED, DESTROYED, LOST AND STOLEN NOTES.

                  If any mutilated Note is surrendered to the Trustee, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Note of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

                  If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Note and
(ii) such security or indemnity as may be required by them to save each of them
and any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Note has been acquired by a bona fide
purchaser, the Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen Note, a
new Note of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

                  In case any such mutilated, destroyed, lost or stolen Note has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Note, pay such Note.

                  Upon the issuance of any new Note under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other

                                      -66-
<PAGE>

expenses (including the fees and expenses of the Trustee) connected therewith.

                  Every new Note issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Notes duly issued hereunder.

                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Notes.

SECTION 307.      PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

                  Interest on any Note which is payable, and is punctually paid
or duly provided for, on any Interest Payment Date shall be paid to the Person
in whose name that Note (or one or more Predecessor Notes) is registered at the
close of business on the Regular Record Date immediately preceding such Interest
Payment Date.

                  Any interest on any Note which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Notes (or their respective
         Predecessor Notes) are registered at the close of business on a Special
         Record Date for the payment of such Defaulted Interest, which shall be
         fixed in the following manner. The Company shall notify the Trustee in
         writing of the amount of Defaulted Interest proposed to be paid on each
         Note and the date of the proposed payment, and at the same time the
         Company shall deposit with the Trustee an amount of

                                      -67-
<PAGE>

         money equal to the aggregate amount proposed to be paid in respect of
         such Defaulted Interest or shall make arrangements satisfactory to the
         Trustee for such deposit prior to the date of the proposed payment,
         such money when deposited to be held in trust for the benefit of the
         Persons entitled to such Defaulted Interest as in this clause provided.
         Thereupon the Trustee shall fix a Special Record Date for the payment
         of such Defaulted Interest which shall be not more than 15 days and not
         less than 10 days prior to the date of the proposed payment and not
         less than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Company of such
         Special Record Date and, in the name and at the expense of the Company,
         shall cause notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor to be mailed, first-class postage
         prepaid, to each Holder at his address as it appears in the Note
         Register, not less than 10 days prior to such Special Record Date.
         Notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor having been so mailed, such Defaulted
         Interest shall be paid to the Persons in whose names the Notes (or
         their respective Predecessor Notes) are registered at the close of
         business on such Special Record Date and shall no longer be payable
         pursuant to the following clause (2).

                  (2) The Company may make payment of any Defaulted Interest in
         any other lawful manner not inconsistent with the requirements of any
         securities exchange on which the Notes may be listed, and upon such
         notice as may be required by such exchange, if, after notice given by
         the Company to the Trustee of the proposed payment pursuant to this
         clause, such manner of payment shall be deemed practicable by the
         Trustee.

                  Subject to the foregoing provisions of this Section, each Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Note shall carry the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Note.

than the Trustee, be delivered to the Trustee and shall be promptly canceled by
it. The Company may at any time deliver to the Trustee for cancellation any
Notes previously authenticated and delivered hereunder which the Company may
have acquired in any manner whatsoever, and all Notes so delivered shall be
promptly canceled by the Trustee. No Notes shall be authenticated in lieu of or
in exchange for any Notes canceled as provided in this Section, except as
expressly permitted by this Indenture. All canceled Notes held by the Trustee
shall be disposed of as directed by a Company Order.

SECTION 310.      COMPUTATION OF INTEREST.

360-day year of twelve 30-day months.

                  The Company in issuing Notes may use "CUSIP" and "ISIN"
numbers (if then generally in use) in addition to serial numbers; if so, the
Trustee shall use such "CUSIP" and "ISIN" numbers in addition to serial numbers
in notices

                                      -69-

of redemption and repurchase as a convenience to Holders; PROVIDED THAT any such
notice may state that no representation is made as to the correctness of such
CUSIP and ISIN numbers either as printed on the Notes or as contained in any
notice of a redemption or repurchase and that reliance may be placed only on the
serial or other identification numbers printed on the Notes, and any such
redemption or repurchase shall not be affected by any defect in or omission of
such CUSIP and ISIN numbers.

                  In the event of a declaration of acceleration of the Notes
because an Event of Default has occurred and is continuing as a result of the
acceleration of any Indebtedness described in clause (5) of this Section 501,
the declaration of acceleration of the Notes shall be automatically annulled if
the Holders of any Indebtedness described in clause (5) of this Section 501 have
rescinded the declaration of acceleration in respect of such Indebtedness within
30 days of the date of such declaration and if:

                  (a)      the annulment of the acceleration of Notes would not
                           conflict with any judgment or decree of a court of
                           competent jurisdiction; and

                  (b)      all existing Events of Default, except nonpayment of
                           principal or interest on the Notes that became due

                           been cured or waived.

SECTION 502.      ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

                  If any Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of the Outstanding Notes may
declare the principal of the Notes to be due and payable immediately; provided,
that so long as any Indebtedness permitted to be incurred pursuant to the Senior
Credit Facilities shall be outstanding, such acceleration shall not be effective
until the earlier of:

                                      -75-
<PAGE>

                  (1)      an acceleration of any such Indebtedness under the
                           Senior Credit Facilities, or

                  (2)      five business days after receipt by the Company and
                           the Chase Manhattan Bank as Administrative Agent to
                           the Senior Credit Facilities at The Chase Manhattan
                           Bank, 270 Park Avenue, New York, New York 10017,
                           Attention: Stephen Rochford (or to such other
                           Administrative Agent as the Trustee may hereafter be
                           notified in writing) of written notice of such
                           acceleration (PROVIDED THAT the notification of the
                           replacement Administrative Agent and its address
                           shall be received by the Trustee prior to the
                           issuance of such notice of acceleration).

                  Notwithstanding the preceding paragraph, in the case of an
Event of Default described in clause (8) or (9) of Section 501, with respect to
the Company or any of its Subsidiaries, the principal and any accrued but unpaid
interest on all Outstanding Notes shall become due and payable immediately
without further action or notice.

                  In the case of any Event of Default occurs on or after August
15, 2004 by reason of any willful action or inaction taken or not taken by or on
behalf of the Company with the intention of avoiding payment of the premium that
the Company would have had to pay if the Company then had elected to redeem the
Notes pursuant to Section 1101 hereof, an equivalent premium shall also become
and be immediately due and payable to the extent permitted by law upon the
acceleration of the Notes. If an Event of Default occurs prior to August 15,
2004 by reason of any willful action (or inaction) taken (or not taken) by or on
behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to such date, then, an additional premium shall
also become immediately due and payable to the extent permitted by law upon
acceleration of the Notes in an amount, for each of the years beginning on
August 15 of the years set forth below, as set forth below (such total amount
due is expressed as a percentage of the principal amount of the Notes on the
date of payment that would otherwise be due but for the provisions of this
sentence):

           YEAR                                                       PERCENTAGE

           1999..................................................     113.000%

           2003..................................................     107.800%

                  At any time after such a declaration of acceleration has been
made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article provided, the Holders of
a majority in aggregate principal amount of the Outstanding Notes or the holders
of a supermajority in aggregate principal amount of the Notes with respect to a
default in respect of any provision requiring a supermajority for an amendment
to such provision, as the case may be, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if (1) the
Company has paid or deposited with the Trustee a sum sufficient to pay (A) all
overdue interest on the Notes,(B) the principal of (and premium, if any, on) any
Notes which have become due otherwise than by such declaration of acceleration
(including any Notes required to have been purchased on the Purchase Date
pursuant to an Offer to Purchase made by the Company) and interest thereon at
the rate provided therefor in the Notes,(C) interest upon overdue interest at
the rate provided therefor in the Notes, and(D) all sums paid or advanced by the
Trustee hereunder and the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel and (2) all existing Events of
Default, other than the non-payment of the principal of, premium, if any, and
interest (and Liquidated Damages, if any) on the Notes which have become due
solely by such declaration of acceleration, have been cured or waived as
provided in Section 513.

                  No such rescission shall affect any subsequent Default or
impair any right consequent thereon.

SECTION 503.      COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
                  TRUSTEE.

                  The Company covenants that if

                  (1) default is made in the payment of any interest (and
         Liquidated Damages, if any) on any Note when such interest (and
         Liquidated Damages, if any) becomes due and payable and such default
         continues for a period of 30 days, or

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Note at the Maturity thereof or, with respect
         to any Note required to have been purchased pursuant to an Asset Sale
         Offer or Change of Control Offer made by the Company, at the Purchase
         Date thereof,

the Company shall, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Notes, the whole amount then due and payable on such Notes for
principal (and premium, if any) and interest (and Liquidated Damages, if any),
and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal (and premium, if any) and on any overdue
interest and Liquidated Damages, at the rate provided by the Notes, and, in
addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

                  If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon the Notes and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon the Notes,
wherever situated.

                  If an Event of Default occurs and is continuing, the Trustee
may in its discretion proceed to protect and enforce its rights and the rights
of the Holders by such judicial proceedings as the Trustee shall deem
appropriate,

                                      -78-
<PAGE>

whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

SECTION 504.      TRUSTEE MAY FILE PROOFS OF CLAIM.

                  In case of any judicial proceeding relative to the Company (or
any other obligor upon the Notes), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized and directed by each Holder to make such
payments to the Trustee and, in the event that the Trustee requests the making
of such payments directly to the Holders, is authorized and directed to pay to
the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.

                  No provision of this Indenture shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding,
PROVIDED, HOWEVER, that the Trustee may, on behalf of the Holders, vote for the
election of a Trustee in bankruptcy or similar official and be a member of a
creditors' or other similar committee.

SECTION 505.      TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF NOTES.

                  All rights of action and claims under this Indenture or the
Notes may be prosecuted and enforced by the Trustee without the possession of
any of the Notes or the production thereof in any proceeding relating thereto,
and any such proceeding instituted by the Trustee shall be

                                      -79-
<PAGE>

brought in its own name as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Notes in respect of which such
judgment has been recovered.

SECTION 506.      APPLICATION OF MONEY COLLECTED.

                  Any money collected by the Trustee pursuant to this Article
shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal
(or premium, if any) or interest (or Liquidated Damages, if any), upon
presentation of the Notes and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

                  FIRST: To the payment of all amounts due the Trustee under
         Section 607;

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of (and premium, if any) and interest (and Liquidated
         Damages, if any) on the Notes in respect of which or for the benefit of
         which such money has been collected, ratably, without preference or
         priority of any kind, according to the amounts due and payable on such
         Notes for principal (and premium, if any) and interest (and Liquidated
         Damages, if any), respectively; and

                  THIRD: To the Company or to such party as a court of competent

         the Outstanding Notes shall have made written request to the Trustee to
         institute proceedings in respect of such Event of Default in its own
         name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         indemnity reasonably satisfactory to the Trustee against the costs,
         expenses and liabilities to be incurred in compliance with such
         request;

                  (4) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Notes;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

Holder of any Note shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 307) interest (and Liquidated Damages, if any) on such Note on the
respective Stated Maturities expressed in such Note (or, in the case of
redemption, on the Redemption Date or in the case of an Asset Sale Offer or
Change of Control Offer made by the Company and required to be accepted as to
such Note, on the Purchase Date) and to institute suit for the enforcement of
any such payment, and such rights shall not be impaired without the consent of
such Holder.

SECTION 509.      RESTORATION OF RIGHTS AND REMEDIES.

                  If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

SECTION 510.      RIGHTS AND REMEDIES CUMULATIVE.

                  Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph

Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

SECTION 511.      DELAY OR OMISSION NOT WAIVER.

                  No delay or omission of the Trustee or of any Holder of any
Note to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to the Holders may be exercised from time to time,
and as often as may be deemed expedient, by the Trustee or by the Holders, as
the case may be.

Outstanding Notes shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee, PROVIDED THAT

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture or involve the Trustee in personal
         liability, and

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

                  The Holders of not less than a majority in aggregate principal
amount of the Outstanding Notes may on behalf of the Holders of all the Notes
waive any existing Default hereunder and its consequences, except a default with
respect to any provision requiring a supermajority to amend, which default may
only be waived by such a supermajority, except a Default

                  (1) in the payment of the principal of (or premium, if any) or
         interest (or Liquidated Damages, if any) on any Note (including any
         Note which is required to have been purchased pursuant to an Asset Sale
         Offer or Change of Control Offer which has been made by the Company),
         or

                  (2) in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Note affected.

                  Upon any such waiver, such Default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon.

this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, a court may require any party litigant in
such suit to file an undertaking to pay the costs of such suit, and may assess
costs, including reasonable attorney's fees and expenses, against any such party
litigant, in the manner and to the extent provided in the Trust Indenture Act;
PROVIDED, that neither this Section nor the Trust Indenture Act shall be deemed
to authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Trustee or the Company.

SECTION 515.      WAIVER OF USURY, STAY OR EXTENSION LAWS.

                  The Company covenants (to the extent that it may lawfully do
so) that it shall not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any usury, stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law and covenants that it shall not hinder, delay or
impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law had
been enacted.

     own funds or otherwise incur any financial liability in the performance of
     any of its duties hereunder, or in the exercise of any of its rights or
     powers, if it shall have reasonable grounds for believing that repayment of
     such funds or adequate indemnity against such risk or liability is not
     reasonably assured to it. Whether or not therein expressly so provided,
     every provision of this Indenture relating to the conduct or affecting the
     liability of or affording protection to the Trustee shall be subject to the

         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, the Trustee shall examine the certificates and
         opinions to determine whether or not they conform to the requirements
         of this Indenture.

                  (c) The Trustee shall have no liability except for its own
     negligent action, its own negligent failure to act, or its own willful
     misconduct, except that:

         made in good faith by a Responsible Officer, unless it is proved that
         the Trustee was negligent in ascertaining the pertinent facts.

                  (3) The Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith

Default or Event of Default within 90 days after it occurs. Except in the case
of a Default or Event of Default in payment of principal of, premium, if any, or

board of directors, the executive committee or a committee of its Responsible
Officers in good faith determines that withholding the notice is in the
interests of the Holders.

SECTION 603.      CERTAIN RIGHTS OF TRUSTEE.

                  Subject to the provisions of Section 601:

         inquiry or investigation, it shall be entitled, upon reasonable prior

         personally or by agent or attorney, at such reasonable times as

                  The recitals contained herein and in the Notes, except the

Company of the Notes or the proceeds thereof.

agent of the Company, in its individual or any other capacity, may become the

         the compensation of a trustee of an express trust);

                  (2) except as otherwise expressly provided herein, to
         reimburse the Trustee upon its request for all reasonable expenses,

collected by the Trustee, in its capacity as Trustee, except assets held in
trust to pay principal of or interest on particular Notes.

                  When the Trustee incurs expenses or renders services after an

effective until the acceptance of appointment by the successor Trustee under
Section 611.

Holders of a majority in principal amount of the Outstanding Notes, delivered to

                  (1) the Trustee shall fail to comply with Section 608 after
         written request therefor by the Company or by any Holder who has been a
         bona fide Holder of a Note for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 609
         and shall fail to resign after written request therefor by the Company
         or by any such Holder, or

         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its

Trustee, or (ii) subject to Section 514, any Holder who has been a bona fide
Holder of a Note for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

                  (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, the Company, by a Board Resolution, shall promptly appoint a
successor Trustee. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Notes delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment, become the successor Trustee and supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed
by the Company or the Holders and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Note for at least six
months may, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the appointment of a successor Trustee.

                  (f) The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to all
Holders in the manner provided in Section 106. Each notice shall include the

retiring Trustee shall become effective and such successor Trustee,

                                      -91-
<PAGE>

without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on request of
the Company or the successor Trustee, such retiring Trustee shall, upon payment
of its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder. Upon request of any such successor
Trustee, the Company shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts.

converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all the corporate
trust business of the Trustee, shall be the successor of the Trustee hereunder,

Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Notes shall have been
authenticated, but not delivered, by the Trustee then in office, any successor

                  The Company shall cause each Paying Agent other than the
Trustee to execute and deliver to the Trustee an instrument in which such Paying
Agent shall agree with the Trustee, subject to the provisions of this Section,
that such Paying Agent shall:

                  (1) hold all sums held by it for the payment of the principal
         of (and premium, if any) or interest (and Liquidated Damages, if any)
         on Notes in trust for the benefit of the Persons entitled thereto until
         such sums shall be paid to such Persons or otherwise disposed of as
         herein provided;

                  (2) give the Trustee notice of any Default by the Company (or
         any other obligor upon the Notes) in the making of any payment of
         principal (and premium, if any) or interest (and Liquidated Damages, if
         any); and

                  (3) at any time during the continuance of any such Default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.

                  The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of (and
premium, if any) or interest (and Liquidated Damages, if any) on any Note and
remaining unclaimed for two years after such principal (and premium, if any) or
interest has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Note shall thereafter, as an unsecured general creditor,
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; PROVIDED, HOWEVER, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in The City of New York, notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication, any unclaimed balance of
such money then remaining shall be repaid to the Company.

Restricted Subsidiaries shall do or cause to be done all things necessary to
preserve and keep in full force and effect their existence, rights (charter and
statutory) and franchises; PROVIDED, HOWEVER, that the Company and Restricted
its Subsidiaries shall not be required to preserve any such right or franchise
if the Board of Directors of the Company in good faith shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company or its Restricted Subsidiaries and that the loss thereof is not
disadvantageous in any material respect to the Holders.

SECTION 1005.     MAINTENANCE OF PROPERTIES.

                                      -104-

necessary repairs, renewals, replacements, betterments and improvements thereof,
all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly and advantageously conducted
at all times; PROVIDED, HOWEVER, that nothing in this Section shall prevent the
Company from discontinuing the operation or maintenance of any of such
properties if such discontinuance is, as determined by the Board of Directors of
the Company in good faith, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect to
the Holders.

SECTION 1006.     PAYMENT OF TAXES AND OTHER CLAIMS.

                  The Company shall pay or discharge or cause to be paid or

materials and supplies which, if unpaid, might by law become a lien upon the
property of the Company or any of its Restricted Subsidiaries; PROVIDED,
HOWEVER, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings or where the failure to effect such payment is not adverse in any
material respect to the Holders.

SECTION 1007.     MAINTENANCE OF INSURANCE.

                  The Company shall, and shall cause its Restricted Subsidiaries
to, keep at all times all of their properties which are of an insurable nature
insured against loss or damage with insurers believed by the Company to be
responsible or in the case of insurance coverage, to self insure in each case to
the extent, in the judgment of the Company, to do so comports with good business
practice.

immediately preceding the date on which such additional Indebtedness is incurred
or such Disqualified Stock or preferred stock is issued (i) for such dates from
the Issue Date up to but not including September 30, 2000, would have been at
least 2 to 1; (ii) for such dates from September 30, 2000 up to but not
including March 31, 2001, would have been at least 2.25 to 1; and (iii)

basis (including a PRO FORMA application of the net proceeds therefrom), as if
the additional Indebtedness had been incurred, or the Disqualified Stock or
preferred stock had been issued, as the case may be, at the beginning of such
four-quarter period.

                  As long as no Default shall have occurred and be continuing or
would be caused thereby, the first paragraph of this Section 1008 shall not

                                    to the prior payment in full in cash of all
                                    Obligations with respect to the Notes, in

                  For purposes of determining compliance with this Section 1008,
in the event that an item of proposed Indebtedness meets the criteria of more
than one of the categories of Permitted Debt described in clauses (1) through
(14) above or is entitled to be incurred pursuant to the first paragraph of this
covenant, the Company shall be permitted to classify such item of Indebtedness
in any manner that complies with this covenant. In addition, the Company may, at
any time, change the classification of an item of Indebtedness (or any portion
thereof) to any other clause or to the first paragraph hereof PROVIDED THAT the
Company would be permitted to incur such item of Indebtedness (or the portion
thereof) pursuant to such other clause or the first paragraph hereof, as the
case may be, at such time of reclassification. Accrual of interest, accretion or
amortization of original issue discount and the accretion of accreted value
shall not be deemed to be an incurrence of Indebtedness for purposes of this
covenant.

                           no more restrictive, in the good faith judgment of
                           the Company's Board of Directors, taken as a whole,

                  Notwithstanding the foregoing, neither (a) customary
provisions restricting subletting or assignment of any lease entered into in the
ordinary course of business, consistent with industry practice, nor (b) Liens
permitted under the terms of this Indenture shall in and of themselves be
considered a restriction on the ability of the applicable Restricted Subsidiary
to transfer such agreement or assets, as the case may be.

SECTION 1011.     LIMITATION ON LIENS SECURING INDEBTEDNESS.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer
to exist or become effective any Lien of any kind securing trade payables,
Attributable Debt or Indebtedness that does not constitute Senior Indebtedness
(other than Permitted Liens) upon any of their property or assets, now owned or
hereafter acquired unless:

                  (1)      in the case of Liens securing Indebtedness that is
                           expressly subordinated or junior in right of payment
                           to the Notes, the Notes are secured on a senior basis
                           to the obligations so secured until such time as such
                           obligations are no longer secured by a Lien; and

                  (2)      in all other cases, the Notes are secured on an equal
                           and ratable basis with the obligations so secured
                           until such time as such obligations are no longer
                           secured by a Lien.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets

understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate or any affiliated professional associations or professional
corporations which employ physicians and other professionals who provide
healthcare services for the Company's occupational and health services centers
(each, an "Affiliate Transaction"), unless:

                  (1)      such Affiliate Transaction is on terms that are no
                           less favorable to the Company or the relevant
                           Restricted Subsidiary than those that would have been
                           obtained in a comparable transaction by the Company
                           or such Restricted Subsidiary made on an arm's-length
                           basis with an unrelated Person; and

                  (2)      the Company delivers to the Trustee:

                           (a)      with respect to any Affiliate Transaction or
                                    series of related Affiliate Transactions
                                    involving aggregate consideration in excess
                                    of $5 million, a resolution of the Board of
                                    Directors set forth in an Officers'
                                    Certificate certifying that such Affiliate
                                    Transaction complies with clause (1) above
                                    and that such Affiliate Transaction has been
                                    approved by a majority of the disinterested
                                    members of the Board of Directors of the
                                    Company; and

                           (b)      with respect to any Affiliate Transaction or

                                    of $15 million, an opinion as to the
                                    fairness to the holders of such Affiliate
                                    Transaction from a financial point of view
                                    issued by an accounting, appraisal or
                                    investment banking firm of national

                  The following items shall not be deemed to be Affiliate

available immediately preceding the date on which Affiliate Management Fees are
to be paid is less than 1.75 to 1 PROVIDED, HOWEVER, that such payments due but
not paid shall accrue and shall be paid only after such time as the Fixed Charge

                  (e)      that, unless the Company defaults in the payment of
                           the Change of Control Payment, all Notes accepted for
                           payment pursuant to the Change of Control Offer shall

                           required to surrender the Notes, with the form
                           entitled "Option of Holder to Elect Purchase" on the

                           election if the Paying Agent receives, not later than
                           the close of business on the

                           second Business Day preceding the Purchase Date, a
                           telegram, telex, facsimile transmission or letter

                           election to have the Notes purchased; and

                  (h)      that Holders whose Notes are being purchased only in
                           part shall be issued new Notes equal in principal
                           amount to the unpurchased portion of the Notes
                           surrendered, which unpurchased portion must be equal
                           to $1,000 in principal amount or an integral multiple
                           thereof.

                  The Company shall comply with the requirements of Rule 14e-1
under the Exchange Act and any other securities laws and regulations thereunder
to the extent such laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control.

                  To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Indenture relating to such
Change of Control Offer, the Company shall comply with the applicable securities
laws and regulations and shall not be deemed to have breached its obligations
described in this Indenture by virtue thereof.

                           Offer;

                  (b)      deposit with the Paying Agent an amount equal to the
                           Change of Control Payment in respect of all Notes or

                  (c)      deliver or cause to be delivered to the Trustee the
                           Notes so accepted together with an Officers'
                           Certificate stating the aggregate principal amount of
                           Notes or portions thereof being purchased by the
                           Company.

                  The Paying Agent shall promptly mail to each Holder of Notes
so tendered the Change of Control Payment for such Notes, and the Trustee shall
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Note equal in principal amount to any unpurchased portion of

Interest Payment Date shall be paid to the Person in whose name a Note is
registered at the close of business on such Record Date, and such interest (and
Liquidated Damages, if applicable) shall not be payable to Holders who tender
the Notes pursuant to such Change of Control Offer.

                  (4) Prior to making a Change of Control Offer pursuant to
paragraph (a), but in any event within 90 days following such Change of Control,
the Company shall (i) obtain any required consents, if any, under all agreements
governing outstanding Senior Indebtedness to permit the making of the Change of
Control Offer and the purchase of Notes pursuant to this Section 1014, or (ii)
repay all or a portion of the outstanding Senior Indebtedness to the extent
necessary (including, if necessary, payment in full of such Indebtedness and

                  (5) Notwithstanding anything to the contrary in this Section
1014, the Company shall not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth

SECTION 1015.     REPURCHASE OF NOTES AT THE OPTION OF THE HOLDER UPON AN
                  ASSET SALE.

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, consummate an Asset Sale unless:

                  (1)      the Company (or the Restricted Subsidiary, as the
                           case may be) receives consideration at the time of
                           such Asset Sale at least equal to the fair market
                           value of the assets or Equity Interests issued or
                           sold or otherwise disposed of;

                  (2)      such fair market value is determined by the Company's
                           Board of Directors and evidenced by a resolution of
                           the Board of Directors set forth in an Officers'
                           Certificate delivered to the Trustee PROVIDED THAT
                           the Board of Directors' determination must be based
                           on an opinion or appraisal issued by an accounting,
                           appraisal or investment banking firm of national
                           standing if such fair market value exceeds $35
                           million; and

                  (3)      at least 75% of the consideration therefor received
                           by the Company or such Restricted Subsidiary is in
                           the form of cash or Cash Equivalents. For purposes of
                           this provision, each of the following shall be deemed
                           to be cash:

                           (a)      any liabilities (as shown on the Company's
                                    or the Restricted Subsidiary's most recent
                                    balance sheet) of the Company or any
                                    Restricted Subsidiary (other than contingent
                                    liabilities and liabilities that are by
                                    their terms subordinated to the Notes or any
                                    Subsidiary Guarantee), that are assumed by
                                    the transferee of any such assets pursuant
                                    to a customary novation agreement that
                                    releases the Company or such Restricted
                                    Subsidiary from further liability; and

                           (b)      any securities, notes or other obligations
                                    received by the Company or any such
                                    Restricted Subsidiary from such transferee
                                    that are contemporaneously (subject to
                                    ordinary settlement periods) converted by
                                    the Company or such Restricted Subsidiary
                                    into cash or Cash Equivalents (to the

                                     -126-
<PAGE>

                                    extent of the cash received in that
                                    conversion).

                  The 75% limitation referred to above shall not apply to any
Asset Sale in which the cash or Cash Equivalents portion of the consideration
received therefrom, determined in accordance with the preceding sentence, is
equal to or greater than what the after-tax proceeds would have been had such
Asset Sale complied with the 75% limitation.

                  Within 270 days after the receipt of any Net Proceeds from an
Asset Sale, the Company or any such Restricted Subsidiary may apply such Net
Proceeds, at its option:

                  (1)      to repay or repurchase Senior Indebtedness of the
                           Company or any Restricted Subsidiary;

                  (2)      to acquire all or substantially all the assets of, or
                           a majority of the Voting Stock of, another Permitted
                           Business;

                  (3)      to make a capital expenditure in a Permitted
                           Business;

                  (4)      to acquire other assets (other than securities) that
                           are used or useful in a Permitted Business; or

                  (5)      to make an Asset Sale Offer, treating the Net
                           Proceeds as Excess Proceeds for all purposes.

                  Any Net Proceeds from Asset Sales that are not applied or
invested as provided in the preceding paragraph shall constitute "Excess
Proceeds". When the aggregate amount of Excess Proceeds exceeds $15 million, the
Company shall be required to make an offer to all Holders of Notes (an "Asset
Sale Offer") to purchase the maximum principal amount of Notes that may be
purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer
shall be equal to 100% of the principal amount plus accrued and unpaid interest,
if any, to the Purchase Date, and shall be payable in cash. If any Excess
Proceeds remain after consummation of an Asset Sale Offer, the Company may use
such Excess Proceeds for general corporate purposes. If the aggregate principal
amount of Notes tendered into such Asset

                                     -127-
<PAGE>

Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the
Notes to be purchased on a pro rata basis. Upon completion of each Asset Sale
Offer, the amount of Excess Proceeds shall be reset at zero.

                  To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Indenture relating to such
Asset Sale Offer, the Company shall comply with the applicable securities laws
and regulations and shall not be deemed to have breached its obligations
described in this Indenture by virtue thereof.

SECTION 1016.     INVESTMENT COMPANY.

                  The Company shall not, and shall not permit any of its
Subsidiaries to, be required to register as an "Investment Company" (as that

Guarantee and this Indenture constitute valid, legal, binding and enforceable
obligations of such Person (subject to customary exceptions concerning
creditors' rights and to equitable principles as may be acceptable to the
Trustee).

                           Officers' Certificate delivered to the Trustee, of

                  The Board of Directors of the Company may designate any

not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted
Subsidiary, all outstanding Investments owned by the Company and its Restricted
Subsidiaries (except to the extent repaid in cash) in the Subsidiary so
designated shall be deemed to be Restricted Payments at the time of such
designation (to the extent not designated a Permitted Investment) and shall

Section 1009. All such outstanding Investments shall be valued at their fair
market value at the time of such designation, as determined in good faith by the
Board of Directors of the Company. That designation shall only be permitted if

Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The
Board of Directors of the Company may redesignate any Unrestricted Subsidiary to
be a Restricted Subsidiary if the redesignation would not cause a Default.

Company in the form of Exhibit D. Each intercompany note shall be payable upon
demand and shall bear interest at the same rate as the Notes.

Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any Holder for or as an inducement to any
consent, waiver or amendment of any of the terms or provisions of this Indenture
or the Notes unless such consideration is offered to be paid and is paid to all
Holders that consent, waive or agree to amend in the time frame set forth in the
solicitation documents relating to such consent, waiver or agreement.

SECTION 1026.     STATEMENT BY OFFICERS AS TO
                  DEFAULT; COMPLIANCE CERTIFICATES.

                  (a) The Company shall deliver to the Trustee, within 90 days
after the end of each fiscal year an Officers' Certificate, stating whether or
not to the best knowledge of the signers thereof the Company is in default in
the performance and observance of any of the terms, provisions and conditions of
Section 801 or Sections 1004 to 1025, inclusive, and if the Company shall be in
default, specifying all such Defaults and the nature and status thereof of which
they may have knowledge.

                  (b) The Company shall deliver to the Trustee, as soon as
possible and in any event within 10 days after the Company becomes aware or
should reasonably become aware of the occurrence of a Default or an Event of
Default, an Officers' Certificate setting forth the details of such Default or
Event of Default, and the action which the Company proposes to take with respect
thereto.

Company shall deliver to the Trustee within 90 days after the end of each fiscal
year a written statement by the Company's independent public accountants stating
(A) that their audit examination has included a review of the terms of this
Indenture and the Notes as they relate to accounting matters, and (B) whether,
in connection with their audit examination, any Default has come to their
attention and, if such a Default has come to their attention, specifying the
nature and period of the existence thereof.

SECTION 1027.     WAIVER OF COVENANTS.

                  The Company may omit in any particular instance to comply with
any covenant or condition set forth in Section 801 and Sections 1004 to 1025, if
before the time for such compliance the Holders of at least a majority in
principal amount of the Outstanding Notes shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such covenant or condition shall remain in full
force and effect; PROVIDED, HOWEVER, with respect to any provision requiring a
supermajority approval to waive, such provision may only be waived by such a
supermajority, and with respect to a covenant or provision which cannot be
modified or amended without the consent of the Holder of each outstanding Note
affected, such provision may only be waived by the consent of each and every
Holder of outstanding Note affected.

                  The following shall be the conditions to application of either
Section 1202 or Section 1203 to the then Outstanding Notes:

                  (1) the Company shall irrevocably have deposited or caused to
         be deposited with the Trustee as trust funds in trust for the purpose
         of making the following payments, specifically pledged as security for,
         and dedicated solely to, the benefit of the Holders of such Notes, in
         U.S. dollars, non-callable Government Securities, or a combination
         thereof, in such amounts as shall be sufficient, in the opinion of a
         nationally recognized firm of independent public accountants, to pay
         the principal of, premium, if any, and interest, Liquidated Damages, if
         any, on the Outstanding Notes on the Stated Maturity of the Notes or on
         the applicable Redemption Date, as the case may be, and the Company
         must specify whether the Notes are being defeased to maturity or to a
         particular Redemption Date;

                  (2) in the case of an election of Legal Defeasance under
         Section 1202, the Company shall have delivered to the Trustee an
         Opinion of Counsel in the United States reasonably acceptable to the
         Trustee confirming that (a) the Company has received from, or there has
         been published by, the Internal Revenue Service a ruling or (b) since
         the Issue Date, there has been a change in the applicable federal
         income tax law, in either case to the effect that, and based thereon
         such Opinion of Counsel shall confirm that, subject to customary
         assumptions and exclusions, the Holders of the Outstanding Notes shall
         not recognize income, gain or loss for federal income tax purposes as a
         result of such Legal Defeasance and shall be subject to federal income
         tax on the same amounts, in the same manner and at the same times as
         would have been the case if such Legal Defeasance had not occurred;

                  (3) in the case of an election of Covenant Defeasance under
         Section 1203, the Company shall have delivered to the Trustee an
         Opinion of Counsel in the United States reasonably acceptable to the
         Trustee confirming that, subject to customary assumptions and
         exclusions, the Holders of the Outstanding Notes shall not recognize
         income, gain or loss for federal income tax purposes as a result of
         such Covenant Defeasance and shall be subject to federal income tax on
         the same

                                     -140-
<PAGE>

         amounts, in the same manner and at the same times as would have been
         the case if such Covenant Defeasance had not occurred;

                  (4) no Default or Event of Default shall have occurred and be
         continuing on the date of such deposit (other than a Default or Event
         of Default resulting from the borrowing of funds to be applied to such
         deposit);

                  (5) such Legal Defeasance or Covenant Defeasance shall not
         result in a breach or violation of, or constitute a default under, any
         material agreement or instrument (other than this Indenture) to which
         the Company or any of its Subsidiaries is a party or by which the
         Company or any of its Subsidiaries is bound;

                  (6) the Company must deliver to the Trustee an Officers'
         Certificate stating that the deposit was not made by the Company or
         with the intent of preferring the Holders over the other creditors of
         the Company or with the intent of defeating, hindering, delaying or
         defrauding creditors of the Company or others;

                  (7) no event which is, or after notice or lapse of time or
         both would become, an Event of Default with respect to such Notes or
         any other Notes shall have occurred and be continuing at the time of
         such deposit or, with regard to any such event specified in paragraphs
         (8) or (9) of Section 501, at any time on or prior to the 90th day
         after the date of such deposit (it being understood that this condition
         shall not be deemed satisfied until after such 90th day); and

                  (8) the Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, which opinion may be
         subject to customary assumptions and exclusions, each stating that all
         conditions precedent provided for relating to either the Legal
         Defeasance under Section 1202 or the Covenant Defeasance under Section
         1203 (as the case may be) have been complied with.

SECTION 1205.     DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD
                  IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

                  Subject to the provisions of the last paragraph of Section
1003, all money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee pursuant to Section 1204 in respect of the Notes
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as its own Paying Agent)
as the Trustee may determine, to the Holders of such Notes, of all sums due and
to become due thereon in respect of principal (and premium, if any) and interest
(and Liquidated Damages, if any), but such money need not be segregated from
other funds except to the extent required by law.

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 1204 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of the Outstanding Notes.

                  Anything in this Article Twelve to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to
time upon Company Request any money or U.S. Government Obligations held by it as
provided in Section 1204 which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

SECTION 1206.     REINSTATEMENT.

                                     -142-
<PAGE>

                  If the Trustee or the Paying Agent is unable to apply any
money in accordance with Section 1202 or 1203 by reason of any order or judgment
of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, or if a Default from a bankruptcy or insolvency
event occurs at any time during the period ending on the 91st day after the date
of a deposit by the Company hereunder, then the Company's obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to this Article Twelve until such time as the Trustee or
Paying Agent is permitted to apply all such money in accordance with Section
1202 or 1203; PROVIDED, HOWEVER, that if the Company makes any payment of
principal of (and premium, if any) or interest (and Liquidated Damages, if any)
on any Note following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive such payment
from the money held by the Trustee or the Paying Agent.

                                  Subordination

SECTION 1301.     AGREEMENT TO SUBORDINATE.

                  The Company agrees, and each Holder by accepting a Note
agrees, that the Indebtedness evidenced by the Notes and all Obligations in
respect of the Notes (including but not limited to Liquidated Damages) are
subordinated in right of payment, to the extent and in the manner provided in
this Article Thirteen, to the prior payment in full in cash of all Senior
Indebtedness (whether outstanding on the date hereof or hereafter created,
incurred, assumed or guaranteed), and that the subordination is for the benefit
of the holders of Senior Indebtedness.

SECTION 1302.     LIQUIDATION; DISSOLUTION; BANKRUPTCY.

                  Upon any distribution of assets of the Company upon any
Insolvency or Liquidation Proceeding:

                  (1) the holders of all Senior Indebtedness of the Company
         shall be entitled to receive payment in full in cash or Cash
         Equivalents before the Holders shall be

                                     -143-
<PAGE>

         entitled to receive any payment on account of the principal of,
         premium, if any, and interest on the Notes or any Obligation in respect
         to the Notes (except that Holders may receive (i) Reorganization
         Securities and (ii) payments made from any defeasance trust created
         pursuant to Section 1201 hereof); and

                  (2) any payment or distribution of assets of the Company of
         any kind or character from any source, whether in cash, property or
         securities (other than (i) Reorganization Securities and (ii) payments
         made from any defeasance trust created pursuant to Section 1201
         hereof), to which the Holders or the Trustee on behalf of the Holders
         would be entitled (by set-off or otherwise), except for this Article,
         shall be paid by the Company or by any receiver, trustee in bankruptcy,
         liquidating trustee, agent or other person making such payment or
         distribution, or by the Holders or by the Trustee if received by them,
         directly to the holders of Senior Indebtedness (PRO RATA to such
         holders on the basis of the amounts of Senior Indebtedness held by such
         holders) or their Representative or Representatives, as their interests
         may appear, for application to the payment of the Senior Indebtedness
         remaining unpaid until all such Senior Indebtedness has been paid in
         full in cash, after giving effect to any concurrent payment,
         distribution or provision therefor to or for the holders of Senior
         Indebtedness.

SECTION 1303.     DEFAULT ON SENIOR INDEBTEDNESS.

                  (a) In the event of and during the continuation of any default
in the payment of principal of, interest or premium, if any, on any Senior
Indebtedness, or any Obligation owing from time to time under or in respect of
Senior Indebtedness, or in the event that any event of default (other than a
payment default) with respect to any Senior Indebtedness shall have occurred and
be continuing and shall have resulted in such Senior Indebtedness becoming or
being declared due and payable prior to the date on which it would otherwise
have become due and payable, then no payment shall be made by or on behalf of
the Company on account of principal of, premium, if any, and interest (and
Liquidated Damages, if any) on the Notes (other than payments in the form of
Reorganization Securities), unless and until such default shall have been cured
or waived in writing in accordance with the instruments governing such Senior
Indebtedness or such acceleration shall have been rescinded or annulled;

                  (b) If any event of default other than as described in clause
(a) above with respect to any Designated Senior Indebtedness shall have occurred
and be continuing permitting the holders of such Designated Senior Indebtedness
(or their Representative or Representatives) to declare such Designated Senior
Indebtedness due and payable prior to the date on which it would otherwise have
become due and payable, then no payment shall be made by or on behalf of the
Company on account of the principal of, premium, if any, and interest (and
Liquidated Damages, if any) on the Notes (other than payments in the form of
Reorganization Securities) during the period (a "Payment Blockage Period")
commencing on the date the Company or the Trustee receives written notice (a
"Payment Notice") of such event of default (which notice shall be binding on the
Trustee and the Holders as to the occurrence of such a payment default or
nonpayment event of default) from the Credit Agent (or other holders of
Designated Senior Indebtedness or their Representative or Representatives) and
ending on the earliest of:

                           (A)      179 days after such date;

                           (B)      the date, if any, on which such Designated
                                    Senior Indebtedness to which such default
                                    relates is paid in full in cash or

                                     -145-
<PAGE>

                                    such default is cured or waived in writing
                                    in accordance with the instruments governing
                                    such Designated Senior Indebtedness by the
                                    holders of such Designated Senior
                                    Indebtedness; and

                           (C)      the date on which the Trustee receives
                                    written notice from the Credit Agent (or
                                    other holders of Designated Senior
                                    Indebtedness or their Representative or
                                    Representatives), as the case may be,
                                    terminating the Payment Blockage Period.

                  (c) During any consecutive 360-day period, the aggregate of
all Payment Blockage Periods shall not exceed 179 days and there shall be a
period of at least 181 consecutive days in each consecutive 360-day period when
no Payment Blockage Period is in effect. No event of default which existed or
was continuing with respect to the Senior Indebtedness for which notice
commencing a Payment Blockage Period was given on the date such Payment Blockage
Period commenced shall be or be made the basis for the commencement of any
subsequent Payment Blockage Period unless such event of default is cured or
waived for a period of not less than 90 consecutive days.

SECTION 1304.     ACCELERATION OF NOTES.

                  If payment of the Notes is accelerated because of an Event of
Default, the Company shall promptly notify holders of Senior Indebtedness of the
acceleration.

SECTION 1305.     WHEN DISTRIBUTION MUST BE PAID OVER.

                  In the event that, notwithstanding the other provisions of
this Article Thirteen, the Trustee receives any payment or distribution in
respect of the Notes or of any Obligations with respect to the Notes at a time
when the Trustee has received notice in accordance with Section 1310 that such
payment or distribution is prohibited by Section 1303 hereof, such payment or
distribution shall be held by the Trustee in trust for the benefit of, and shall
be paid forthwith over and delivered, upon written request, to, the holders of
Senior Indebtedness remaining unpaid or unprovided for or their representative
or representatives, or to the trustee or trustees under any indenture pursuant
to which any instruments representing any of such Senior Indebtedness may have
been issued, ratably according to aggregate principal amounts remaining unpaid
on account of such Senior Indebtedness held or represented by each, for
application to the payment of all obligations with respect to Senior
Indebtedness remaining unpaid, to the extent necessary to pay or to provide for
the payment of all such obligations in full in cash or Cash Equivalents in
accordance with their terms, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

                  In the event that, notwithstanding the other provisions of
this Article Thirteen, a Holder receives any payment or distribution of any
Obligations with respect to the Notes at a time when such payment or
distribution is prohibited by Section 1303 hereof, such payment or distribution
shall be paid forthwith over and delivered, upon written request, to, the
holders of Senior Indebtedness remaining unpaid or unprovided for or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments representing any of such Senior
Indebtedness may have been issued, ratably according to aggregate principal
amounts remaining unpaid on account of such Senior Indebtedness held or
represented by such, for application to the payment of all obligations with
respect to Senior Indebtedness remaining unpaid, to the extent necessary to pay
or to provide for the payment of all such obligations in full in cash or Cash
Equivalents in accordance with their terms, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.

                                     -147-
<PAGE>

                  With respect to the holders of Senior Indebtedness, the
Trustee undertakes to perform only such obligations on the part of the Trustee
as are specifically set forth in this Article Thirteen, and no implied covenants
or obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness, and shall not be
liable to any such holders if the Trustee shall pay over or distribute to or on
behalf of Holders or the Company or any other Person money or assets to which
any holders of Senior Indebtedness shall be entitled by virtue of this Article
Thirteen, except if such payment is made as a result of the willful misconduct
or gross negligence of the Trustee.

SECTION 1306.     NOTICE BY COMPANY.

                  The Company shall promptly notify the Trustee and the Paying
Agent of any facts known to the Company that would cause a payment of any
Obligations with respect to the Notes to violate this Article Thirteen, but
failure to give such notice shall not affect the subordination of the Notes to
the Senior Indebtedness as provided in this Article Thirteen.

SECTION 1307.     SUBROGATION.

                  After all Senior Indebtedness is paid in full in cash or Cash
Equivalents and until the Notes are paid in full, Holders shall be subrogated
(equally and ratably with all other Indebtedness PARI PASSU with the Notes) to
the rights of holders of Senior Indebtedness to receive distributions applicable
to Senior Indebtedness to the extent that distributions otherwise payable to the
Holders have been applied to the payment of Senior Indebtedness. A distribution
made under this Article Thirteen to holders of Senior Indebtedness that
otherwise would have been made to Holders is not, as between the Company and
Holders, a payment by the Company on the Notes. No holder of Senior Indebtedness
shall be obligated to create, warrant, preserve or protect any such subrogation
right or shall suffer any loss or diminution of its rights hereunder if for any
reason such right of subrogation is not available to any Holder.

                                     -148-
<PAGE>

SECTION 1308.     RELATIVE RIGHTS.

                  This Article defines the relative rights of Holders and
holders of Senior Indebtedness. Nothing in this Indenture shall:

                  (1) impair, as between the Company and Holders, the obligation
         of the Company, which is absolute and unconditional, to pay principal
         of (and premium, if any) and interest (and Liquidated Damages, if any)
         on the Notes in accordance with their terms;

                  (2) affect the relative rights of Holders and creditors of the
         Company other than their rights in relation to holders of Senior
         Indebtedness; or

                  (3) prevent the Trustee or any Holder from exercising its
         available remedies upon a Default or Event of Default, subject to the
         rights of holders of Senior Indebtedness to receive distributions and
         payments otherwise payable to Holders.

                  If the Company fails because of this Article to pay principal
of (or premium, if any) or interest (or Liquidated Damages, if any) on a Note on
the due date, the failure is still a Default or Event of Default.

SECTION 1309.     SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY.

                  No right of any holder of Senior Indebtedness to enforce the
subordination of the Indebtedness evidenced by the Notes shall be impaired by
any act or failure to act by the Company or any Holder or by the failure of the
Company or any holder of Senior Indebtedness to comply with this Indenture.

                  Without in any way limiting the generality of the foregoing
paragraph, the holders of the Senior Indebtedness may, at any time and from time
to time, without the consent of or notice to the Trustee or Holders, without
incurring responsibility to the Holders and without impairing or releasing the
subordination provided in this Article Thirteen or the obligations hereunder of
the Holders to the holders of Senior Indebtedness, do any one or more of the
following: (a) change the manner, place or terms of payment

                                     -149-
<PAGE>

or extend the time or payment of, or renew or alter, Senior Indebtedness or any
instrument evidencing the same or any agreement under which Senior Indebtedness
is outstanding; PROVIDED, HOWEVER, that any such alteration shall not (i)
increase the amount of Senior Indebtedness outstanding in a manner prohibited by
this Indenture or (ii) otherwise violate Section 1008 hereof; (b) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Indebtedness; (c) release any Person in any manner for
the collection of Senior Indebtedness; and (d) exercise or refrain from
exercising any rights against the Company or any other Person; PROVIDED,
HOWEVER, that in no event shall any such actions limit the right of the Holders
to take any action to accelerate the maturity of the Notes in accordance with
the provisions set forth in Section 502 or to pursue any rights or remedies
against the parties to this Indenture under this Indenture or under applicable
laws if the taking of such action does not otherwise violate the terms of this
Article Thirteen.

SECTION 1310.     RIGHTS OF TRUSTEE AND PAYING AGENT.

                  Notwithstanding the provisions of this Article Thirteen or any
other provision of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts that would prohibit the making of any
payment or distribution by the Trustee, and the Trustee and the Paying Agent may
continue to make payments on the Notes, unless the Trustee shall have received
at its Corporate Trust Office at least five Business Days prior to the date of
such payment written notice of facts that would cause the payment of any
Obligations with respect to the Notes to violate this Article Thirteen. Only the
Company or the Representative may give the notice. Nothing in this Article
Thirteen shall impair the claims of, or payments to, the Trustee under or
pursuant to Section 607 hereof.

                  The Trustee in its individual or any other capacity may hold
Senior Indebtedness with the same rights it would have if it were not Trustee.

                                     -150-
<PAGE>

SECTION 1311.     AUTHORIZATION TO EFFECT SUBORDINATION.

                  Each Holder of a Note by the Holder's acceptance thereof
authorizes and directs the Trustee on the Holder's behalf to take such action as
may be necessary or appropriate to effectuate the subordination as provided in
this Article Thirteen, and appoints the Trustee to act as the Holder's
attorney-in-fact for any and all such purposes. If the Trustee does not file a
proper proof of claim or proof of Indebtedness in the form required in any
proceeding referred to in Section 504 hereof at least 30 days before the
expiration of the time to file such claim, the Representative is hereby
authorized to file an appropriate claim for and on behalf of the Holders.

SECTION 1312.     AMENDMENTS.

                  The provisions of this Article Thirteen or any related
definitions shall not be amended or modified in a manner adverse to the holders
of Senior Indebtedness without the written consent of the holders of all Senior
Indebtedness.

<PAGE>

                  Subject to the provisions of this Article Fourteen, each
Guarantor, jointly and severally, hereby irrevocably and unconditionally fully
guarantees to each Holder of a Note authenticated and delivered by the Trustee
and to the Trustee and its successors and assigns (the "Subsidiary Guarantee"),
that: (a) the principal of, and premium, if any, and interest (and Liquidated
Damages, if any) on the Notes shall be duly and punctually paid in full when
due, whether at maturity, by acceleration or otherwise, and interest on overdue
principal, and premium, if any, and (to the extent permitted by law) interest on
any interest and Liquidated Damages, if any, on the Notes and all other
obligations of the Company to the Holders or the Trustee hereunder or under the
Notes (including fees, expenses or other) shall be promptly paid in full or
performed, all in accordance with the terms hereof; and (b) in case of any
extension of time of payment or renewal of any Notes or any of such other
obligations, the same shall be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at stated
maturity, by acceleration or otherwise. Failing payment when due of any amount
so guaranteed or failing performance of any other obligation of the Company to
the Holders, for whatever reason, each Guarantor shall be obligated to pay, or
to perform or to cause the performance of, the same immediately. An Event of
Default under this Indenture or the Notes shall constitute an event of default
under the Subsidiary Guarantees, and shall entitle the Trustee or the Holders to
accelerate the obligations of each Guarantor hereunder in the same manner and to
the same extent as the obligations of the Company. Each Guarantor hereby agrees
that its obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder
with respect to any thereof, the entry of any judgment against the Company, any
action to enforce the same or any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor. Each
Guarantor hereby waives and relinquishes: (a) any right to require the Trustee,
the Holders or the Company (each, a "Benefitted Party") to proceed against the
Company, the Subsidiaries or any other Person or to proceed against or exhaust
any security held by a Benefitted Party at any time or to pursue any other
remedy in any secured party's power before proceeding against the Subsidiaries;
(b) any defense that may arise by reason of the incapacity, lack of

                                     -152-
<PAGE>

authority, death or disability of any other Person or Persons or the failure of
a Benefitted Party to file or enforce a claim against the estate (in
administration, bankruptcy or any other proceeding) of any other Person or
Persons; (c) demand, protest and notice of any kind (except as expressly
required by this Indenture), including but not limited to notice of the
existence, creation or incurring of any new or additional Indebtedness or
obligation or of any action or non-action on the part of the Guarantors, the
Company, the Subsidiaries, any Benefitted Party, any creditor of the Guarantors,
the Company or the Subsidiaries or on the part of any other Person whomsoever in
connection with any obligations the performance of which are hereby guaranteed;
(d) any defense based upon an election of remedies by a Benefitted Party,
including but not limited to an election to proceed against the Guarantors for
reimbursement; (e) any defense based upon any statute or rule of law which
provides that the obligation of a surety must be neither larger in amount nor in
other respects more burdensome than that of the principal; (f) any defense
arising because of a Benefitted Party's election, in any proceeding instituted
under the Bankruptcy Law, of the application of Section 1111(b)(2) of the
Bankruptcy Code; and (g) any defense based on any borrowing or grant of a
security interest under Section 364 of the Bankruptcy Code. The Guarantors
hereby covenant that the Subsidiary Guarantees shall not be discharged except by
payment in full of all principal, premium, if any, and interest on the Notes and
all other costs provided for under this Indenture, or except as provided in
Sections 1202 and 1404.

                  If any Holder or the Trustee is required by any court or
otherwise to return to either the Company or the Guarantors, or any trustee or
similar official acting in relation to either the Company or the Guarantors, any
amount paid by the Company or the Guarantors to the Trustee or such Holder, the
Subsidiary Guarantees, to the extent theretofore discharged, shall be reinstated
in full force and effect. Each of the Guarantors agrees that it shall not be
entitled to any right of subrogation in relation to the Holders in respect of
any obligations guaranteed hereby until payment in full of all obligations
guaranteed hereby. Each Guarantor agrees that, as between it, on the one hand,
and the Holders and the Trustee, on the other hand, (x) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article Five
hereof for the purposes hereof, notwithstanding any stay, injunction or

                                     -153-
<PAGE>

other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any acceleration of such obligations
as provided in Article Five hereof, such obligations (whether or not due and
payable) shall forthwith become due and payable by such Guarantor for the
purpose of its Subsidiary Guarantee.

SECTION 1402.     EXECUTION AND DELIVERY OF SUBSIDIARY GUARANTEES.

                  To evidence the Subsidiary Guarantees set forth in Section
1401 hereof, each of the Guarantors agrees that a Subsidiary Guarantee
substantially in the form of Exhibit C hereto shall be endorsed on each Note
authenticated and delivered by the Trustee and that this Indenture shall be
executed on behalf of such Guarantor by its Chairman of the Board, its President
or one of its Vice Presidents, and attested to by its Secretary or one of its
Assistant Secretaries.

                  Each of the Guarantors agrees that the Subsidiary Guarantees
set forth in this Article Fourteen shall remain in full force and effect and
apply to all the Notes notwithstanding any failure to endorse on each Note a
notation of the Subsidiary Guarantees.

                  If an individual whose manual or facsimile signature is on a
Note shall have ceased to hold such office prior to the authentication and
delivery of the Note on which the Subsidiary Guarantees are endorsed, the
Subsidiary Guarantees shall be valid nevertheless.

                  The delivery of any Note by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of the
Subsidiary Guarantees endorsed thereon and set forth in this Indenture and shall
bind each Guarantor notwithstanding the fact that a Subsidiary Guarantee does
not bear the signature of such Guarantor. Each of the Guarantors hereby jointly
and severally agrees that its Subsidiary Guarantee set forth in Section 1401 and
in the form of Subsidiary Guarantee established pursuant to Exhibit C shall
remain in full force and effect notwithstanding any failure to endorse a
Subsidiary Guarantee on any Note.

SECTION 1403.     GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.


                                     -154-
<PAGE>

                  (a) Nothing contained in this Indenture or in the Notes shall
         prevent any consolidation or merger of a Guarantor with or into the
         Company or another Guarantor, or shall prevent the transfer of all or
         substantially all of the assets of a Guarantor to the Company or
         another Guarantor. Upon any such consolidation, merger, transfer or
         sale, the Subsidiary Guarantee of such Guarantor shall no longer have
         any force or effect.

                  (b) Except as provided in Section 1403(a), or a transaction
         referred to in Section 1404, no Guarantor shall consolidate with or
         merge with or into (whether or not such Guarantor is the surviving
         corporation) another Person other than the Company or another
         Guarantor, whether in a single transaction or a series of related
         transactions, unless (i) subject to the provisions of Section 1404
         hereof, the Person formed by or surviving any such consolidation or
         merger (if other than such Guarantor) assumes all the obligations of
         such Guarantor in connection with the Subsidiary Guarantees and this
         Indenture pursuant to a supplemental indenture in a form reasonably
         satisfactory to the Trustee, pursuant to which such Person shall
         unconditionally guarantee on a senior subordinated basis all of such
         Guarantor's obligations under such Guarantor's Subsidiary Guarantee and
         this Indenture on the terms set forth in this Indenture; (ii)
         immediately before and immediately after giving effect to such
         transaction on a PRO FORMA basis, no Default or Event of Default shall
         have occurred and be continuing; and (iii) such Guarantor shall have
         delivered to the Trustee an Officers' Certificate and an Opinion of
         Counsel addressed to the Trustee, each stating that such consolidation
         or merger and such supplemental indenture, if any, comply with this
         Indenture and that such supplemental indenture is enforceable. In case
         of any such consolidation or merger and upon the assumption by the
         successor corporation, by supplemental indenture, executed and
         delivered to the Trustee and satisfactory in form to the Trustee, of
         the Subsidiary Guarantees endorsed upon the Notes and the due and
         punctual performance of all of the covenants and conditions of this
         Indenture to be performed by such Guarantor, such successor corporation
         shall succeed to and be substituted for such Guarantor

                                     -155-
<PAGE>

         with the same effect as if it had been named herein as a Guarantor.
         Such successor corporation thereupon may cause to be signed any or all
         of the Subsidiary Guarantees to be endorsed upon all of the Notes
         issuable hereunder which theretofore shall have been signed by the
         Company and delivered to the Trustee. All the Subsidiary Guarantees so
         issued shall in all respects have the same legal rank and benefit under
         this Indenture as the Subsidiary Guarantees theretofore and thereafter
         issued in accordance with the terms of this Indenture as though all of
         such Subsidiary Guarantees had been issued at the date of the execution
         hereof.

                  (c) The Trustee, subject to the provisions of Section 1404
         hereof, shall be entitled to receive an Officers' Certificate and an
         Opinion of Counsel as conclusive evidence that any such consolidation,
         merger, sale or conveyance, and any such assumption of obligations,
         comply with the provisions of this Section 1403.

SECTION 1404.     RELEASES FOLLOWING SALE OF ASSETS.

                  Upon the sale or disposition (whether by merger, stock
purchase, asset sale or otherwise) of a Guarantor (or all or substantially all
of the assets of any such Guarantor or 50% or more of the Equity Interests of
any such Guarantor) to an entity which is not a Guarantor or the designation of
a Subsidiary to become an Unrestricted Subsidiary, which transaction is
otherwise in compliance with this Indenture, including without limitation
Section 1015 hereof, such Guarantor shall be deemed released from its
obligations under its Subsidiary Guarantee. Upon delivery by the Company to the
Trustee of an Officer's Certificate and Opinion of Counsel, to the effect that
such sale or other disposition was made by the Company in accordance with the
provisions of this Indenture, including without limitation Section 1015 hereof,
the Trustee shall execute any documents reasonably required in order to evidence
the release of any such Guarantor from its obligations under its Subsidiary
Guarantee. Any Guarantor not released from its obligations under its Subsidiary
Guarantee shall remain liable for the full amount of principal of and interest
on the Notes and for the other

                                     -156-
<PAGE>

obligations of any Guarantor under this Indenture as provided in this Article
Fourteen.

SECTION 1405.     LIMITATION OF GUARANTOR'S LIABILITY.

                  Each Guarantor, and by its acceptance hereof each Holder,
hereby confirms that it is the intention of all such parties that the guarantee
by such Guarantor pursuant to its Subsidiary Guarantee not constitute a
fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the
Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any
similar federal or state law. To effectuate the foregoing intention, the Holders
and such Guarantor hereby irrevocably agree that the obligations of such
Guarantor under this Article Fourteen shall be limited to the maximum amount as
shall, after giving effect to all other contingent and fixed liabilities of such
Guarantor and after giving effect to any collections from or payments made by or
on behalf of any other Guarantor in respect of the obligations of such other
Guarantor under this Article Fourteen, result in the obligations of such
Guarantor under the Subsidiary Guarantee of such Guarantor not constituting a
fraudulent transfer or conveyance.

SECTION 1406.     APPLICATION OF CERTAIN TERMS AND PROVISIONS TO THE GUARANTORS.

                  (a) For purposes of any provision of this Indenture which
         provides for the delivery by any Guarantor of an Officers' Certificate
         and/or an Opinion of Counsel, the definitions of such terms in Section
         101 shall apply to such Guarantor as if references therein to the
         Company were references to such Guarantor.

                  (b) Any request, demand, authorization, direction, notice,
         consent, waiver or other document which by any provision of this
         Indenture is to be made by any Guarantor, shall be sufficient if
         evidenced as described in Section 105 as if references therein to the
         Company were references to such Guarantor.

                  (c) Any request, demand, authorization, direction, notice,
         consent, waiver or Act of Holders or other document which by any
         provision of this Indenture

                                     -157-
<PAGE>

         is required or permitted to be given or served by the Trustee or by any
         Holder may be given or served as described in Section 105 as if
         references therein to the Company were references to such Guarantor.

                  (d) Upon any application or request by any Guarantor to the
         Trustee to take any action under any provision of this Indenture, such
         Guarantor shall furnish to the Trustee such certificates and opinions
         as are required in Section 102 hereof as if all references therein to
         the Company were references to such Guarantor.

SECTION 1407.     RELEASE OF SUBSIDIARY GUARANTEES.

                  Concurrently with the defeasance of the Notes under Section
1202 hereof, the Guarantors shall be released from all of their obligations
under the Subsidiary Guarantees and this Article Fourteen.

SECTION 1408.     SUBORDINATION OF SUBSIDIARY GUARANTEES.

                  The obligations of each Guarantor under its Subsidiary
Guarantee pursuant to this Article Fourteen is subordinated in right of payment
to the prior payment in full in cash of all Senior Indebtedness of such
Guarantor on the same basis as the Notes are subordinated to Senior Indebtedness
of the Company. For the purposes of the foregoing sentence, the Trustee and the
Holders shall have the right to receive and/or retain payments by any of the
Guarantors only at such times as they may receive and/or retain payments in
respect of Notes pursuant to this Indenture, including Article Thirteen hereof.
In the event that the Trustee receives any Guarantor payment at a time when the
Trustee has received notice in accordance with Section 1310, such Guarantor
payment shall be held by the Trustee in trust for the benefit of, and shall be
paid forthwith over and delivered, upon written request, to, the holders of the
Senior Indebtedness of such Guarantor remaining unpaid or unprovided for, for
application to the payment of all obligations with respect to Senior
Indebtedness of such Guarantor remaining unpaid, to the extent necessary to pay
such Senior Indebtedness of such Guarantor in full in accordance with their
terms, after giving effect to any concurrent payment or distribution to

                                     -158-
<PAGE>

or for the holders of Senior Indebtedness. In the event that a Holder receives
any Guarantor payment at a time when such payment is prohibited by the second
preceding sentence, such Guarantor payment shall be forthwith paid over and
delivered to the holders of the Senior Indebtedness of such Guarantor remaining
unpaid or unprovided for, for application to the payment of all obligations with
respect to Senior Indebtedness of such Guarantor remaining unpaid, to the extent
necessary to pay such Senior Indebtedness in full in accordance with their
terms, after giving effect to any concurrent payment or distribution to or for
the holders of Senior Indebtedness of such Guarantor.

                  Each Holder of a Note by its acceptance thereof (a) agrees to
and shall be bound by the provisions of this Section 1408, (b) authorizes and
directs the Trustee on the Holder's behalf to take such action as may be
necessary and appropriate to effectuate the subordination so provided, and (c)
appoints the Trustee as the Holder's attorney-in-fact for any and all such
purposes.

SECTION 1409.     WAIVER OF SUBROGATION.


                                     -159-
<PAGE>

                  Until this Indenture is discharged and all of the Notes are
discharged and paid in full, each Guarantor hereby irrevocably waives and agrees
not to exercise any claim or other rights which it may now or hereafter acquire
against the Company that arise from the existence, payment, performance or
enforcement of the Company's obligations under the Notes or this Indenture and
each Guarantor's obligations under this Subsidiary Guarantee and this Indenture,
in any such instance including, without limitation, any right of subrogation,
reimbursement, exoneration, contribution, indemnification, and any right to
participate in any claim or remedy of the Holders and the Trustees against the
Company, whether or not such claim, remedy or right arises in equity, or under
contract, statute or common law, including, without limitation, the right to
take or receive from the Company, directly or indirectly, in cash or other
property or by set-off or in any other manner, payment or security on account of
such claim or other rights. If any amount shall be paid to a Guarantor in
violation of the preceding sentence and any amounts owing to the Trustee or the
Holders under the Notes, this Indenture, or any other document or instrument
delivered under or in connection with such agreements or instruments, shall not
have been paid in full, such amount shall have been deemed to have been paid to
such Guarantor for the benefit of, and held in trust for the benefit of, the
Holders and the Trustee and shall forthwith be paid to the Trustee for the
benefit of such Holders to be credited and applied to the obligations in favor
of the Holders, whether matured or unmatured, in accordance with the terms of
this Indenture. Each Guarantor acknowledges that it has received consideration
for providing the Subsidiary Guarantee and that it shall receive direct and
indirect benefits from the financing arrangements contemplated by this Indenture
and that the waiver set forth in this Section 1409 is knowingly made in
contemplation of such benefits.

SECTION 1410.     IMMEDIATE PAYMENT.

                  Each Guarantor agrees to make immediate payment to the Trustee
on behalf of the Holders of all obligations under the Notes and this Indenture
owing or payable to the Holders upon receipt of a demand for payment therefor by
the Trustee to such Guarantor in writing.

                                     -160-
<PAGE>

SECTION 1411.     NO SET-OFF.

                  Each payment to be made by any Guarantor hereunder in respect
of the Notes, the Subsidiary Guarantees or this Indenture shall be payable in
U.S. Dollars and shall be made without set-off, counterclaim, reduction or
diminution of any kind or nature.

SECTION 1412.     OBLIGATIONS ABSOLUTE.

                  The obligations of each Guarantor hereunder are and shall be
absolute and unconditional and any monies or amounts expressed to be owing or
payable by a Guarantor hereunder which may not be recoverable from such
Guarantor on the basis of a guarantee shall be recoverable from such Guarantor
as a primary obligor and principal debtor in respect thereof.

SECTION 1413.     OBLIGATIONS CONTINUING.

                  Subject to Section 1404, the obligations of each Guarantor
hereunder shall be continuing and shall remain in full force and effect until
all the obligations of the Company under the Notes and this Indenture shall have
been paid and satisfied in full.

SECTION 1414.     OBLIGATIONS NOT REDUCED.

                  The obligations of each Guarantor hereunder shall not be
satisfied, reduced or discharged by any intermediate payment or satisfaction of
the whole or any part of the principal, interest, fees and other monies or
amounts which may at any time be or become owing or payable under or by virtue
of or otherwise in connection with the Notes or this Indenture.

SECTION 1415.     OBLIGATIONS REINSTATED.

                  The obligations of each Guarantor hereunder shall continue to
be effective or shall be reinstated, as the case may be, if at any time any
payment which would otherwise have reduced the obligations of a Guarantor
hereunder (whether such payment shall have been made by or on behalf

                                     -161-
<PAGE>

of the Company or by or on behalf of a Guarantor) is rescinded or reclaimed from
the Holders upon the insolvency, bankruptcy, liquidation or reorganization of
the Company or any Guarantor or otherwise, all as though such payment had not
been made. If demand for, or acceleration of the time for, payment by the
Company is stayed upon the insolvency, bankruptcy, liquidation or reorganization
of the Company, all such indebtedness otherwise subject to demand for payment or
acceleration shall nonetheless be payable by each Guarantor as provided herein.

SECTION 1416.     OBLIGATIONS NOT AFFECTED.

                  The obligations of each Guarantor hereunder shall not be
affected, impaired or diminished in any way by any act, omission, matter or
thing whatsoever, occurring before, upon or after any demand for payment
hereunder (and whether or not known or consented to by a Guarantor or the
Holders) which, but for this provision, might constitute a whole or partial
defense to a claim against a Guarantor hereunder or might operate to release or
otherwise exonerate any Guarantor from any of its obligations hereunder or
otherwise affect such obligations, whether occasioned by default of any of the
Holders or otherwise, including, without limitation:

                  (1) any limitation of status or power, disability, incapacity
         or other circumstance relating to the Company or any other person,
         including any insolvency, bankruptcy, liquidation, reorganization,
         readjustment, composition, dissolution, winding-up or other proceeding
         involving or affecting the Company or any other person;

         in respect of any indebtedness or other obligation of the Company or
         any other person under this Indenture, the Notes or any other document
         or instrument;

                  (3) any failure of the Company, whether or not without fault
         on its part, to perform or comply with any of the provisions of this
         Indenture or the Notes, or to give notice thereof to a Guarantor;

                                     -162-

         against the Company or any other person or their respective assets or
         the release or discharge of any such right or remedy;

                  (5) the granting of time, renewals, extensions, compromises,
         concessions, waivers, releases, discharges and other indulgences to the
         Company or any other person;

                  (6) any change in the time, manner or place of payment of, or
         in any other term of, any of the Notes, or any other amendment,
         variation, supplement, replacement or waiver of, or any consent to
         departure from, any of the Notes or this Indenture, including, without
         limitation, any increase or decrease in the principal amount of or
         premium, if any, or interest on any of the Notes;

                  (7) subject to Section 1404, any change in the ownership,
         control, name, objects, businesses, assets, capital structure or
         constitution of the Company or any Guarantor;

                  (8) subject to Section 1404, any merger or amalgamation of the
         Company or a Guarantor with any person or persons;

                  (9) the occurrence of any change in the laws, rules,

         Guarantor under its Subsidiary Guarantee; and

                  (10) any other circumstance (other than by complete,
         irrevocable payment) that might otherwise constitute a legal or
         equitable discharge or defense of the Company under this Indenture or
         the Notes or of a Guarantor in respect of its Subsidiary Guarantee
         hereunder.

Company designated as its 13% [Series A][Series B] Senior Subordinated Notes due

Indenture referred to below) in aggregate principal amount to $190,000,000,

called the "Indenture"), between the Company, the Guarantors named therein and
United States Trust Company of New York, as Trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee, the holders of Senior
Indebtedness and the Holders of the Notes and of the terms upon which the Notes
are, and are to be, authenticated and delivered.

                  The Notes are subject to redemption upon not less than 30 nor
more than 60 days' notice by mail, at any time on or after August 15, 2004, as a
whole or in part, at the election of the Company, at a Redemption Price which,
if during the twelve month period beginning August 15, 2004 is equal to 106.500%
of the principal amount of this Note; if during the twelve month period
beginning August 15, 2005 is equal to 104.875% of the principal amount of this
Note; if during the twelve month period beginning August 15, 2006 is equal to

is on or prior to such Redemption Date will be payable to the Holders of such
Notes, or one or more Predecessor Notes, of record at the close of business on
the relevant Record Dates referred to on the face hereof, all as provided in the
Indenture.

                  At any time prior to August 15, 2002, the Company may on one
or more occasions redeem up to 25% of the

                                       A-9
<PAGE>

aggregate principal amount of Notes originally issued under the Indenture at a
Redemption Price of 113% of the principal amount thereof, plus accrued and
unpaid interest to the Redemption Date, with the Net Cash Proceeds of one or
more Equity Offerings; PROVIDED THAT:

         (a)      at least 75% of the aggregate principal amount of Notes
                  remains outstanding immediately after the occurrence of such
                  redemption (excluding Notes held by the Company and its
                  Subsidiaries); and

         (b)      the redemption must occur within 90 days of the date of the

not be redeemable at the Company's option prior to August 15, 2004.

                  The Notes do not have the benefit of any sinking fund
obligations.

                  In the event of redemption or purchase pursuant to an Asset
Sale Offer or Change of Control Offer of this Note in part only, a new Note or
Notes for the unredeemed portion hereof will be issued in the name of the Holder
hereof upon the cancellation hereof.

                  The indebtedness evidenced by this Note is, to the extent
provided in the Indenture, subordinate and subject in right of payment to the
prior payment in full of all Senior Indebtedness, and this Note is issued
subject to the provisions of the Indenture with respect thereto. Each Holder of
this Note, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
action as may be necessary or appropriate to effectuate the subordination so
provided and (c) appoints the Trustee his attorney-in-fact for any and all such
purposes.

may be declared due and payable the principal amount of the Notes, in the manner
and with the effect provided in the Indenture. Upon any acceleration of maturity
of the Notes, all principal of and accrued interest and Liquidated Damages, if
any, on the Notes shall be due and payable immediately.

specified percentages in aggregate principal amount of the Notes at the time
Outstanding, on behalf of the Holders of all the Notes, to waive compliance by

Holder of this Note shall be conclusive and binding upon such Holder and upon
all future Holders of this Note and of any Note issued upon the registration of
transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Note.

Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of (and premium, if
any) and interest (and Liquidated Damages, if any) on this Note at the times,

Indenture and subject to certain limitations therein set forth, Notes are

                  No service charge will be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

notice, request and offer of indemnity. The foregoing shall not apply to any
suit instituted by the Holder of this Note for the enforcement of any payment of
principal hereof or

                                      A-12

               INDENTURE, dated as of August 17, 1999, between Concentra Managed
Care, Inc., a corporation duly organized and existing under the laws of the
State of Delaware (herein called the "Company"), having its principal office at
312 Union Wharf, Boston, Massachusetts 02109 and United States Trust Company of
New York, a bank and trust company duly organized under the New York Banking
Law, as Trustee (herein called the "Trustee").

               Each party agrees as follows for the benefit of each other and
for the equal and ratable benefit of the Holders of the Company's 14% Senior
Discount Debentures due 2010 (the "Debentures"):


                                   ARTICLE ONE

                        Definitions and Other Provisions
                             of General Application

SECTION 101.   DEFINITIONS.

               For all purposes of this Indenture, except as otherwise expressly
provided or unless the context otherwise requires:

               (1) the terms defined in this Article have the meanings assigned
        to them in this Article and include the plural as well as the singular;

               (2) all other terms used herein which are defined in the Trust
        Indenture Act, either directly or by reference therein, have the
        meanings assigned to them therein;

               (3) all accounting terms not otherwise defined herein have the
        meanings assigned to them in accordance with GAAP;

               (4) unless otherwise specifically set forth herein, all
        calculations or determinations of a Person shall be performed or made on
        a consolidated basis in accordance with GAAP; and

               (5) the words "herein", "hereof" and "hereunder" and other words
        of similar import refer to this Indenture as a whole and not to any
        particular Article, Section or other subdivision.

               Certain terms, used principally in Article Six, are defined in
that Article.

               "Accreted Value" means, as of any date of determination prior to
the Full Accretion Date, with respect to any Debenture, the sum of (a) the
initial offering price based on

<PAGE>

an aggregate initial offering price of $110,000,000 and (b) the aggregate amount
that shall have accreted on such Debenture through such date, such amount to be
so accreted on a daily basis at a rate of 14% per annum of the initial offering
price of such Debenture, compounded semi-annually on each February 15 and August
15 from the date of issuance of the Debenture through the date of determination,
computed on the basis of a 360-day year of twelve 30-day months. On February 15,
2005 and on each subsequent Interest Payment Date, the Accreted Value of the
Debenture shall be reduced by the amount of accrued original issue discount
required to be paid on such Debenture pursuant to Section 301(c) hereof. In the
event of any such payment of accrued original issue discount, the Accreted Value
of the Debenture shall be further reduced as of its maturity date to the extent
necessary to ensure that the yield to maturity on the Debenture (determined as
provided in Section 1272 of the Code and the regulations thereunder and computed
by taking into account any such payment of accrued original issue discount)
shall equal the yield to maturity on such Debenture (computed as though no such
payment of accrued original discount had been paid). At the request of the
Trustee, the Company shall calculate the Accreted Value with respect to any
Debenture and deliver such calculation to the Trustee. The Trustee shall be
entitled to rely conclusively on the Company's calculation.

               "Acquired Debt" means, with respect to any specified Person:

               (1)    Indebtedness of any other Person existing at the time such
                      other Person is merged with or into or became a Subsidiary
                      of such specified Person or assumed in connection with the
                      acquisition of assets from such Person, whether or not
                      such Indebtedness is incurred in connection with, or in
                      contemplation of, such other Person merging with or into,
                      or becoming a Subsidiary of such specified Person or such
                      acquisition, and

               (2)    Indebtedness secured by a Lien encumbering any asset
                      acquired by such specified Person.

               "Act", when used with respect to any Holder, has the meaning
specified in Section 104.

               "Affiliate" of any specified Person means any other Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with such specified Person. For purposes of this definition,
"control," as used with respect to any Person, shall mean the possession,
directly or indirectly, of the power to direct or cause the direction of the
management or policies of such Person, whether through the ownership of voting
securities, by agreement or otherwise, PROVIDED that beneficial ownership of 10%
or more of the Voting Stock of a Person shall be deemed to be control. For
purposes of this definition, the terms "controlling," "controlled by" and "under
common control with" shall have correlative meanings; PROVIDED that any
affiliated professional associations and professional corporations which employ
physicians and other professionals who provide health care services for the
Company's


                                       2
<PAGE>

occupational health services centers shall not be deemed to be an
Affiliate of the Company or any of its Subsidiaries.

               "Affiliate Management Fees" means any management, consulting,
monitoring or advisory fees, and related expenses, payable to Welsh Carson,
Ferrer Freeman or their respective Affiliates.

              "Affiliate Transaction" has the meaning set forth in Section 1012.

              "Asset Sale" means:

               (1)    the sale, lease (other than an operating lease entered
                      into in the ordinary course of business), conveyance or
                      other disposition (a "Disposition") of any assets or
                      rights (other than the licensing of its non-exclusive
                      intellectual property rights) (including, without
                      limitation, by way of a sale and leaseback), provided that
                      the Disposition of all or substantially all of the assets
                      of the Company and its Restricted Subsidiaries taken as a
                      whole shall be governed by Section 1014 and/or by Section
                      801 and not by Section 1015; and

               (2)    the issue or sale by the Company or any of its Restricted
                      Subsidiaries of Equity Interests of any of the Company's
                      Restricted Subsidiaries (other than directors' qualifying
                      shares), that, in the case of either clause (1) or (2) and
                      whether in a single transaction or a series of related
                      transactions:

                      (a)    has a fair market value in excess of $5 million, or

                      (b)    is for net proceeds to the Company and its
                             Restricted Subsidiaries in excess of $5 million.

Notwithstanding the preceding, the following items shall not be deemed to be
Asset Sales:

               (1)    a transfer of assets among the Company, its Wholly Owned
                      Restricted Subsidiaries and its Permitted Joint Ventures;

               (2)    an issuance of Equity Interests by a Wholly Owned

                      shall be excluded, but only to the extent that the
                      obligations giving rise to such Fixed Charges shall not be
                      obligations of the specified Person or any of its
                      Restricted Subsidiaries following the Calculation Date.

               For purposes of this definition, whenever PRO FORMA effect is to
be given to an Investment or an acquisition or disposition of assets, the amount
of income or earnings relating thereto and the amount of Consolidated Interest
Expense associated with any Indebtedness incurred in connection therewith, or
any other calculation under this definition, the PRO FORMA calculations shall be
determined in good faith by a responsible financial or accounting officer of the
Company (including PRO FORMA expense and cost reductions calculated on a basis

bears a floating rate of interest and is being given PRO FORMA effect, the
interest expense on such Indebtedness shall be calculated as if the rate in

period (taking into account any interest rate agreement applicable to such
Indebtedness if such interest rate agreement has a remaining term in excess of
12 months).

                      indirect obligation (a) to subscribe for additional Equity
                      Interests or (b) to maintain or preserve such Person's
                      financial condition or to cause such Person to achieve any
                      specified levels of operating results;

               (4)    has not guaranteed or otherwise directly or indirectly
                      provided credit support for any Indebtedness of the
                      Company or any of its Restricted Subsidiaries; and

               (5)    has at least one director on its board of directors that
                      is not a director or executive officer of the Company or
                      any of its Restricted Subsidiaries and has at least one
                      executive officer that is not a director or executive
                      officer of the Company or any of its Restricted
                      Subsidiaries.

               Any designation of a Subsidiary of the Company as an Unrestricted
Subsidiary shall be evidenced to the Trustee by filing with the Trustee a
certified copy of the Board Resolution giving effect to such designation and an
Officers' Certificate certifying that such designation complied with the
preceding conditions and was permitted by the covenant described in Section
1009. If, at any time, any Unrestricted Subsidiary would fail to meet the
preceding requirements as an Unrestricted Subsidiary, it shall thereafter cease
to be an Unrestricted Subsidiary for purposes of this Indenture and any
Indebtedness of such Subsidiary shall be deemed to be incurred by a Restricted
Subsidiary of the Company as of such date and, if such Indebtedness is not
permitted to be incurred as of such date under Section 1008, the Company shall
be in default of such covenant. The Board of Directors of the Company may at any
time designate any Unrestricted Subsidiary to be a Restricted Subsidiary;
provided that such designation shall be deemed to be an incurrence of
Indebtedness by a Restricted Subsidiary of the Company of any outstanding
Indebtedness of such Unrestricted Subsidiary and such designation shall be
permitted only if: (1) such Indebtedness is permitted under Section 1008, and
(2) no Default or Event of Default would be in existence following such
designation.

               Upon any application or request by the Company to the Trustee to
take any action under any provision of this Indenture, the Company shall furnish
to the Trustee such certificates and opinions as it may reasonably request or as
may be required under the Trust Indenture Act. Each such certificate or opinion
shall be given in the form of an Officers' Certificate, if to be given by an
officer of the Company, or an Opinion of Counsel, if to be given by counsel, and
shall comply with the requirements of the Trust Indenture Act and any other
requirement set forth in this Indenture.

                                       34
<PAGE>

               Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

               (1) a statement that each individual signing such certificate or
        opinion has read such covenant or condition and the definitions herein

               (4) a statement as to whether, in the opinion of each such
        individual, such condition or covenant has been complied with.


SECTION 103.   FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

               In any case where several matters are required to be certified
by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

               Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations

erroneous. Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous. An Opinion of Counsel may have qualifications customary
for opinions of the type required and counsel delivering such Opinion of Counsel
may rely on certificates of government or other officials customary for opinions
of the type required.

<PAGE>

               Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

SECTION 104.   ACTS OF HOLDERS; RECORD DATE.

               (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

               (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

               (c) The ownership of Debentures shall be proved by the Debentures
Register.

               (d) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Debenture shall bind every
future Holder of the same Debenture and the Holder of every Debenture issued
upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the
Trustee or the Company in reliance thereon, whether or not notation of such
action is made upon such Debenture.

               (e) The Company may set any day as a record day for the purpose
of determining the Holders of Outstanding Debentures entitled to give, make or
take any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken
by Holders of Debentures, provided that the Company may not set a record date
for, and the provisions of this paragraph shall not apply with respect to, the
giving or making of any notice, declaration, request or direction referred to in
the next


                                       36
<PAGE>

paragraph. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Debentures on such record date, and no other Holders, shall be
entitled to take the relevant action, whether or not such Holders remain Holders
after such record date; provided that no such action shall be effective
hereunder unless taken on or prior to the applicable Expiration Date by Holders
of the requisite principal amount of Outstanding Debentures on such record date.
Nothing in this paragraph shall be construed to prevent the Company from setting
a record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount at maturity of
Outstanding Debentures on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each
Holder in the manner set forth in Section 106.

               The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Debentures entitled to join in the giving
or making of (i) any Notice of Default, (ii) any declaration of acceleration
referred to in Section 502, (iii) any request to institute proceedings referred
to in Section 507(2) or (iv) any direction referred to in Section 512. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Debentures on such record date, and no other Holders, shall be entitled to join
in such notice, declaration, request or direction, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount at maturity of Outstanding
Debentures on such record date. Nothing in this paragraph shall be construed to
prevent the Trustee from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be canceled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount at maturity of Outstanding Debentures on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Trustee,
at the Company's expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be given to the Company
in writing and to each Holder in the manner set forth in Section 106.

               With respect to any record date set pursuant to this Section, the
party hereto which sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder in the manner set forth in Section 106, on or prior
to the existing Expiration Date. If an Expiration Date is not designated with
respect to any record date set pursuant to this Section, the party hereto which
set such record date shall be deemed to have


                                       37
<PAGE>

initially designated the 180th day after such record date as the Expiration Date
with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph.

               (f) Without limiting the foregoing, a Holder entitled hereunder
to take any action hereunder with regard to any particular Debenture may do so
with regard to all or any part of the Accreted Value of such Debenture or by one
or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such Accreted Value.


SECTION 105.   NOTICES, ETC., TO TRUSTEE AND COMPANY.

               Any request, demand, authorization, direction, notice, consent,
waiver or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with,

               (1) the Trustee by any Holder or by the Company shall be
        sufficient for every purpose hereunder if made, given, furnished or
        filed in writing to or with the Trustee at its Corporate Trust Office at
        United States Trust Company of New York, 114 West 47th Street, New York,
        New York 10036-1532, Attention: Corporate Trust Administration, or

               (2) the Company by the Trustee or by any Holder shall be
        sufficient for every purpose hereunder (unless otherwise herein
        expressly provided) if in writing and mailed, first-class postage
        prepaid, to the Company addressed to it at the address of its principal
        office specified in the first paragraph of this instrument or at any
        other address previously furnished in writing to the Trustee by the
        Company.

               Notice to the Trustee shall not be effective until it is actually
received.


                                       38
<PAGE>

SECTION 106.   NOTICE TO HOLDERS; WAIVER.

               Where this Indenture provides for notice to Holders of any event,
such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at his address as it appears in the Debenture Register,
not later than the latest date (if any), and not earlier than the earliest date
(if any), prescribed for the giving of such notice. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

               In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.


SECTION 107.   CONFLICT WITH TRUST INDENTURE ACT.

               If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be part
of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.


SECTION 108.   EFFECT OF HEADINGS AND TABLE OF CONTENTS.

               The Article and Section headings herein and the Table of Contents
are for convenience only and shall not affect the construction hereof.


SECTION 109.   SUCCESSORS AND ASSIGNS.

               All covenants and agreements in this Indenture by the Company
shall bind its successors and assigns, whether so expressed or not.

SECTION 110.   SEPARABILITY CLAUSE.

               In case any provision in this Indenture or in the Debentures
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.


SECTION 111.   BENEFITS OF INDENTURE.

               Nothing in this Indenture or in the Debentures, express or
implied, shall give to any Person, other than the parties hereto and their
successors hereunder and the Holders, any benefit or any legal or equitable
right, remedy or claim under this Indenture.




<PAGE>


SECTION 112.   GOVERNING LAW.

               THIS INDENTURE AND THE DEBENTURES SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO
CONFLICTS OF LAWS PRINCIPLES THERETO.


SECTION 113.   LEGAL HOLIDAYS.

               In any case where any Interest Payment Date, Redemption Date,
Purchase Date or Stated Maturity of any Debenture shall not be a Business Day,
then (notwithstanding any other provision of this Indenture or of the
Debentures) payment of interest or Accreted Value (and premium, if any) need not
be made on such date, but may be made on the next succeeding Business Day with
the same force and effect as if made on the Interest Payment Date, Redemption
Date or Purchase Date, or at the Stated Maturity, PROVIDED that to the extent
such payment is made on such next succeeding Business Day, no interest shall
accrue for the period from and after such Interest Payment Date, Redemption
Date, Purchase Date or Stated Maturity, as the case may be.


SECTION 114.   NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND
STOCKHOLDERS.

               No director, officer, employee, incorporator or stockholder of
the Company, as such, shall have any liability for any obligations of the
Company under the Debentures, this Indenture or for any claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder by
accepting a Debenture waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Debentures.

                                 Debenture Forms

SECTION 201.   FORMS GENERALLY.

               The Debentures (including the Trustee's certificates of
authentication) shall be in substantially the form set forth in Exhibit A with
such appropriate insertions, omissions, substitutions and other variations as
are required or permitted by this Indenture, and may have such letters, numbers
or other marks of identification and such legends or endorsements placed thereon
as may be required to comply with the rules of any securities exchange or as
may, consistently herewith, be determined by the officers executing such
Debentures, as evidenced by their execution of the Debentures.

               The Definitive Debentures endorsed thereon shall be printed,
lithographed or engraved or produced by any combination of these methods on
steel engraved borders or may be produced in any other manner permitted by the
rules of any securities exchange on which the Debentures may be listed, all as
determined by the officers executing such Debentures, as evidenced by their
execution of such Debentures.

               The Debentures shall be initially issued as Definitive Debentures
which are Transfer Restricted Debentures. If in subsequent transfers the
Debentures are offered and sold to QIB's in reliance on Rule 144A or in offshore
transactions in reliance on Regulation S, the purchasers thereof may exchange
such Definitive Debentures for a beneficial interest in a global Debenture in
conformity with the customary requirements of The Depository Trust Company (the
"Depositary") and registered in the name of the Depositary or its nominee, in
each case for credit to an account of a direct or indirect participant in the
Depositary.

               Any such Debenture issued to a QIB shall be represented by one or
more Debentures in registered global form without interest coupons
(collectively, the "Rule 144A Global Debenture") and any such Debenture issued
in connection with offshore transactions in reliance on Regulation S shall, if
such Debentures are subject to the restricted period pursuant to Rule 903 (the
"restricted period"), be represented by one or more temporary Debentures in
registered global form without interest coupons (collectively, the "Regulation S
Temporary Global Debenture") and if not so restricted, by one or more permanent
registered global Debentures without interest coupons (the "Regulation S
Permanent Global Debentures" and together with the Regulation S Temporary Global
Debenture, the "Regulation S Global Debenture"). The Regulation S Global
Debenture shall be deposited on behalf of the subscribers thereof with a
custodian for the Depositary. The Regulation S Global Debenture shall be
registered in the name of a nominee of the Depositary for credit to the
subscribers' respective


                                       41
<PAGE>

accounts at Euroclear System ("Euroclear") and CEDEL Bank, S.A. ("CEDEL").
Beneficial interests in the Regulation S Global Debenture may be held only
through Euroclear or CEDEL.

               If applicable, within a reasonable period of time after the
expiration of the restricted period, the Regulation S Temporary Global Debenture
shall be exchanged for one or more Regulation S Permanent Global Debentures upon
delivery to the Trustee of certification as provided in Section 305(f) hereof.
During the restricted period, beneficial interests in the Regulation S Temporary
Global Debenture may be held only through Euroclear or CEDEL (as indirect
participants in the Depositary), and, pursuant to the Depositary's procedures,
beneficial interests in the Regulation S Temporary Global Debenture may not be
transferred to a Person that takes delivery thereof in the form of an interest
in the Rule 144A Global Debenture. After the restricted period, (i) beneficial
interests in the Regulation S Permanent Global Debentures may be transferred to
a Person that takes delivery in the form of an interest in the Rule 144A Global
Debenture and (ii) beneficial interests in the Rule 144A Global Debenture may be
transferred to a Person that takes delivery in the form of an interest in the
Regulation S Permanent Global Debentures, PROVIDED, that the certification
requirements described in Section 305(e) hereof are complied with.

               Any Debenture transferred pursuant to an effective registration
statement under the Securities Act or pursuant to the exemption from
registration provided by Rule 144 may be exchanged in accordance with Section
305 for Unrestricted Debentures. Unrestricted Debentures initially shall be
represented by one or more Debentures in registered global form without interest
coupons (collectively, the "Unrestricted Global Debentures"). The Unrestricted
Global Debenture shall be deposited with the Trustee as custodian for the
Depository in New York, New York and registered in the name of the Depository or
its nominee, in each case for credit to an account of a direct or indirect
participant in the Depository.

               (a) The aggregate principal amount at maturity of Notes which may
be authenticated and delivered under this Indenture is limited to $216,230,000,
except for Debentures authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, other Debentures pursuant to Section 304,
305, 306, 906 or 1108 or in connection with an Asset Sale Offer or Change of
Control Offer pursuant to Sections 1015 or 1014, respectively.

               The Debentures shall be known and designated as the "14% Senior

August 15, 2010.

                                       42

               The Debentures are general unsecured obligations of the Company
that shall rank PARI PASSU in right of payment to all existing and future Senior
Indebtedness of the Company and senior to all existing and future subordinated
Indebtedness of the Company.

               (b) The Company will pay interest semi-annually in arrears on
each Interest Payment Date, or if any such day is not a Business Day, on the
next succeeding Business Day, commencing on February 15, 2005. The Debentures
will not bear or accrue cash interest until August 15, 2004. Cash interest on
the Debentures will accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from August 15, 2004. The Company shall
make each interest payment to the Holders of record on the immediately preceding
February 1 and August 1 until the principal amount at maturity thereof is paid
or made available for payment, and at the rate of 15% per annum on any overdue

               registration requirements of the Securities Act and with all
               applicable securities laws of the States of the United States, a
               certification from such Holder to that effect (in substantially
               the form set forth on the reverse of the Debenture) and an
               Opinion of Counsel from the Holder reasonably acceptable to the
               Company, the Trustee, and to the Debenture Registrar to the

                             (C)   if such beneficial interest is being

               Registrar to the effect that such transfer is in compliance with
               the Securities Act,

then the Trustee shall cause, or direct the Debentures Custodian to cause, in

maturity of the Global Debenture to be reduced accordingly and, following such

               (j) CANCELLATION AND/OR ADJUSTMENT OF GLOBAL DEBENTURE. At such
time as all beneficial interests in a Global Debenture have either been
exchanged for Definitive Debentures or beneficial interests in other Global
Debentures, redeemed, repurchased or canceled, such Global Debenture shall be
returned to or retained and canceled by the Trustee. At any time prior to such
cancellation, if any beneficial interest in a Global Debenture is exchanged for
Definitive Debentures or a beneficial interest in another Global Debenture,
redeemed, repurchased or canceled, the principal amount at maturity of
Debentures represented by such Global Debenture shall be reduced and an
endorsement shall be made on such Global Debenture, by the Trustee or the
Debentures Custodian, at the direction of the Trustee, to reflect such
reduction.

               (k) OBLIGATIONS WITH RESPECT TO TRANSFERS AND EXCHANGES OF
DEFINITIVE DEBENTURES. To permit registrations of transfers and exchanges, the
Company shall execute and the Trustee shall authenticate Definitive Debentures
and Global Debentures at the Debenture Registrar's request.

               (l) GENERAL. No service charge shall be made for any registration
of transfer or exchange of Debentures, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any registration of transfer or exchange of Debentures, other
than exchanges pursuant to Section 304, 906 or 1108 or in accordance with any
Asset Sale Offer or Change of Control Offer pursuant to Section 1015 or 1014,
respectively, not involving any transfer.

               The Company shall not be required (i) to issue, register the
transfer of or exchange any Debenture during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Debentures selected for redemption under Section 1104 and ending at the close of
business on the day of such mailing, or (ii) to register the transfer of or


                                       53

the unredeemed portion of any Debenture being redeemed in part.


SECTION 306.   MUTILATED, DESTROYED, LOST AND STOLEN DEBENTURES.

               If any mutilated Debenture is surrendered to the Trustee, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Debenture of like tenor and principal amount at maturity and
bearing a number not contemporaneously outstanding.

               If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Debenture and (ii) such security or indemnity as may be required by them to save
each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Debenture has been acquired by a
bona fide purchaser, the Company shall execute and upon its request the Trustee
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Debenture, a new Debenture of like tenor and principal amount at maturity and
bearing a number not contemporaneously outstanding.

               In case any such mutilated, destroyed, lost or stolen Debenture
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Debenture, pay such Debenture.

               Upon the issuance of any new Debenture under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

               Every new Debenture issued pursuant to this Section in lieu of
any mutilated, destroyed, lost or stolen Debenture shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Debenture shall be at any time enforceable by anyone,
and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Debentures duly issued hereunder.

               The provisions of this Section are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Debentures.

SECTION 307.   PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

               Interest on any Debenture which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date shall be paid to the
Person in whose name that Debenture (or one or more Predecessor Debentures) is
registered at the close of business on the Regular Record Date immediately
preceding such Interest Payment Date.

               Any interest on any Debenture which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

               (1) The Company may elect to make payment of any Defaulted
        Interest to the Persons in whose names the Debentures (or their
        respective Predecessor Debentures) are registered at the close of
        business on a Special Record Date for the payment of such Defaulted
        Interest, which shall be fixed in the following manner. The Company
        shall notify the Trustee in writing of the amount of Defaulted Interest
        proposed to be paid on each Debenture and the date of the proposed
        payment, and at the same time the Company shall deposit with the Trustee
        an amount of money equal to the aggregate amount proposed to be paid in
        respect of such Defaulted Interest or shall make arrangements
        satisfactory to the Trustee for such deposit prior to the date of the
        proposed payment, such money when deposited to be held in trust for the
        benefit of the Persons entitled to such Defaulted Interest as in this
        clause provided. Thereupon the Trustee shall fix a Special Record Date
        for the payment of such Defaulted Interest which shall be not more than
        15 days and not less than 10 days prior to the date of the proposed
        payment and not less than 10 days after the receipt by the Trustee of
        the notice of the proposed payment. The Trustee shall promptly notify
        the Company of such Special Record Date and, in the name and at the
        expense of the Company, shall cause notice of the proposed payment of
        such Defaulted Interest and the Special Record Date therefor to be
        mailed, first-class postage prepaid, to each Holder at his address as it
        appears in the Debenture Register, not less than 10 days prior to such
        Special Record Date. Notice of the proposed payment of such Defaulted
        Interest and the Special Record Date therefor having been so mailed,
        such Defaulted Interest shall be paid to the Persons in whose names the
        Debentures (or their respective Predecessor Debentures) are registered
        at the close of business on such Special Record Date and shall no longer
        be payable pursuant to the following clause (2).

               (2) The Company may make payment of any Defaulted Interest in any
        other lawful manner not inconsistent with the requirements of any
        securities exchange on which the Debentures may be listed, and upon such
        notice as may be required by such exchange, if, after notice given by
        the Company to the Trustee of the proposed payment

                                       55
<PAGE>

pursuant to this clause, such manner of payment shall be deemed practicable
by the Trustee.

               Subject to the foregoing provisions of this Section, each
Debenture delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Debenture shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Debenture.


SECTION 308.   PERSONS DEEMED OWNERS.

               Prior to due presentment of a Debenture for registration of

may treat the Person in whose name such Debenture is registered as the owner of
such Debenture for the purpose of receiving payment of Accreted Value of (and
premium, if any) and (subject to Section 307) interest on such Debenture and for
all other purposes whatsoever, whether or not such Debenture be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.


SECTION 309.   CANCELLATION.

               All Debentures surrendered for payment, redemption, registration
of transfer or exchange or any Asset Sale Offer or Change of Control Offer
pursuant to Section 1015 or 1014, respectively shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee and shall be promptly
canceled by it. The Company may at any time deliver to the Trustee for
cancellation any Debentures previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and all Debentures
so delivered shall be promptly canceled by the Trustee. No Debentures shall be
authenticated in lieu of or in exchange for any Debentures canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Debentures held by the Trustee shall be disposed of as directed by a Company
Order.


SECTION 310.   COMPUTATION OF INTEREST.

               Interest on the Debentures shall be computed on the basis of a
360-day year of twelve 30-day months.

                                       56
<PAGE>

               The Company in issuing Debentures may use "CUSIP" and "ISIN"
numbers (if then generally in use) in addition to serial numbers; if so, the
Trustee shall use such "CUSIP" and "ISIN" numbers in addition to serial numbers
in notices of redemption and repurchase as a convenience to Holders; PROVIDED
that any such notice may state that no representation is made as to the
correctness of such CUSIP and ISIN numbers either as printed on the Debentures
or as contained in any notice of a redemption or repurchase and that reliance
may be placed only on the serial or other identification numbers printed on the
Debentures, and any such redemption or repurchase shall not be affected by any
defect in or omission of such CUSIP and ISIN numbers.

                      order for relief or any such other decree or order

                      applicable Federal or State bankruptcy, insolvency,
                      reorganization or other similar law or of any other case
                      or proceeding to be adjudicated a bankrupt or insolvent,

                      Significant Subsidiaries of the Company in an involuntary
                      case or proceeding under any applicable Federal or State

                      seeking reorganization or relief under any applicable

                      such Subsidiary to the filing of such petition or to the

                                       60
<PAGE>

                      Subsidiaries that are Significant Subsidiaries of the
                      Company, or the making by the Company or any of its
                      Restricted Subsidiaries that are Significant
                      Subsidiaries of the Company of an assignment for the
                      benefit of creditors, or the admission by the Company or
                      any such Subsidiary in writing of its inability to pay
                      its debts generally as they become due, or the taking of
                      corporate action by the Company or any such Significant
                      Subsidiary in furtherance of any such action.

               Notwithstanding any provision herein to the contrary, the
nonpayment of any amounts required to be paid by the Company pursuant to Section
301(c) shall not constitute a Default or an Event of Default; PROVIDED HOWEVER
that during any period of any such nonpayment the Debentures shall accrue
interest at the rate borne by the Debentures plus 1% per annum.

               In the event of a declaration of acceleration of the Debentures
because an Event of Default has occurred and is continuing as a result of the
acceleration of any Indebtedness described in clause (5) of this Section 501,
the declaration of acceleration of the Debentures shall be automatically
annulled if the holders of any Indebtedness described in clause (5) of this
Section 501 have rescinded the declaration of acceleration in respect of such
Indebtedness within 30 days of the date of such declaration and if:

               (a)    the annulment of the acceleration of Debentures would not
                      conflict with any judgment or decree of a court of
                      competent jurisdiction; and

               (b)    all existing Events of Default, except nonpayment of
                      Accreted Value or interest on the Debentures that became
                      due solely because of the acceleration of the Debentures,
                      have been cured or waived.


SECTION 502.   ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

               If any Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount at maturity of the Outstanding
Debentures may declare all of the Debentures to be due and payable immediately
in an amount equal to (x) the Accreted Value of the Debentures outstanding on
the date of acceleration, if such declaration is made prior to the Full
Accretion Date or (y) the entire principal amount at maturity of all the
Debentures outstanding on the date of acceleration plus accrued interest, if
any, to the date of acceleration if such declaration is made after the Full
Accretion Date.

               Notwithstanding the preceding paragraph, in the case of an Event
of Default described in clause (7) or (8) of Section 501, with respect to the
Company or any of its


                                       61
<PAGE>

Subsidiaries, all Outstanding Debentures shall become due and payable
immediately without further action or notice in an amount equal to (x) the
Accreted Value of the Debentures outstanding on the date of acceleration, if
such declaration is made prior to the Full Accretion Date or (y) the entire
principal amount at maturity of all the Debentures outstanding on the date of
acceleration plus accrued interest, if any, to the date of acceleration if such
declaration is made after the Full Accretion Date.

               In the case any Event of Default occurs by reason of any willful
action or inaction taken or not taken by or on behalf of the Company with the
intention of avoiding payment of the premium that the Company would have had to
pay if the Company then had elected to redeem the Debentures pursuant to Section
1101 hereof, an equivalent premium shall also become and be immediately due and
payable to the extent permitted by law upon the acceleration of the Debentures.

               At any time after such a declaration of acceleration has been
made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article provided, the Holders of
a majority in aggregate principal amount at maturity of the Outstanding
Debentures, by written notice to the Company and the Trustee, may rescind and
annul such declaration and its consequences if the Company has paid or deposited
with the Trustee a sum sufficient to pay and except on default with respect to
any provision requiring a supermajority approval to amend, which may only be
waived by such supermajority, all existing Events of Default, other than the
non-payment of the Accreted Value of, premium, if any, and interest on the
Debentures which have become due solely by such declaration of acceleration,
have been cured or waived as provided in Section 513.

               No such rescission shall affect any subsequent Default or impair
any right consequent thereon.


SECTION 503.   COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

               Subject to the second paragraph of Section 501, the Company
covenants that if

               (1) default is made in the payment of any interest on any
        Debenture when such interest becomes due and payable and such default
        continues for a period of 30 days, or

               (2) default is made in the payment of the Accreted Value of (or
        premium, if any, on) any Debenture at the Maturity thereof or, with
        respect to any Debenture required to have been purchased pursuant to an
        Asset Sale Offer or Change of Control Offer made by the Company, at the
        Purchase Date thereof,

                                       62
<PAGE>

the Company shall, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Debentures, the whole amount then due and payable on such
Debentures for Accreted Value (and premium, if any) and, if after the Full
Accretion Date, interest, and, to the extent that payment of such interest shall
be legally enforceable, interest on any overdue principal (and premium, if any)
and on any overdue interest, at the rate provided by the Debentures, and, in
addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

               If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon the Debentures
and collect the moneys adjudged or decreed to be payable in the manner provided
by law out of the property of the Company or any other obligor upon the
Debentures, wherever situated.

               If an Event of Default occurs and is continuing, the Trustee may
in its discretion proceed to protect and enforce its rights and the rights of
the Holders by such judicial proceedings as the Trustee shall deem appropriate,
whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

SECTION 504.   TRUSTEE MAY FILE PROOFS OF CLAIM.

               In case of any judicial proceeding relative to the Company (or
any other obligor upon the Debentures), its property or its creditors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized and directed by each Holder to make such
payments to the Trustee and, in the event that the Trustee requests the making
of such payments directly to the Holders, to pay to the Trustee any amount due
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 607.

               No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Debentures or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding, PROVIDED,
HOWEVER, that the Trustee may, on behalf of the Holders, vote for the


                                       63
<PAGE>

election of a Trustee in bankruptcy or similar official and be a member of a
creditors' or other similar committee.


SECTION 505.   TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF DEBENTURES.

               All rights of action and claims under this Indenture or the
Debentures may be prosecuted and enforced by the Trustee without the possession
of any of the Debentures or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Debentures in respect of which such
judgment has been recovered.


SECTION 506.   APPLICATION OF MONEY COLLECTED.

               Any money collected by the Trustee pursuant to this Article shall
be applied in the following order, at the date or dates fixed by the Trustee
and, in case of the distribution of such money on account of Accreted Value (or
premium, if any) or interest, upon presentation of the Debentures and the
notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

               FIRST:  To the payment of all amounts due the Trustee under
Section 607;

               SECOND: To the payment of the amounts then due and unpaid for
        Accreted Value of (and premium, if any) and, if after the Full Accretion
        Date, interest on the Debentures in respect of which or for the benefit
        of which such money has been collected, ratably, without preference or
        priority of any kind, according to the amounts due and payable on such
        Debentures for Accreted Value (and premium, if any) and, if after the
        Full Accretion Date, interest, respectively; and

               THIRD: The balance, if any, to the Company.


SECTION 507.   LIMITATION ON SUITS.

               No Holder of any Debenture shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless

                                       64
<PAGE>

               (1) such Holder has previously given written notice to the
        Trustee of a continuing Event of Default;

               (2) the Holders of not less than 25% in principal amount at
        maturity of the Outstanding Debentures shall have made written request
        to the Trustee to institute proceedings in respect of such Event of
        Default in its own name as Trustee hereunder;

               (3) such Holder or Holders have offered to the Trustee indemnity
        reasonably satisfactory to the Trustee against the costs, expenses and
        liabilities to be incurred in compliance with such request;

               (4) the Trustee for 60 days after its receipt of such notice,
        request and offer of indemnity has failed to institute any such
        proceeding; and

               (5) no direction inconsistent with such written request has been
        given to the Trustee during such 60-day period by the Holders of a
        majority in principal amount at maturity of the Outstanding Debentures;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

SECTION 508.   UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE ACCRETED
                      VALUE, PREMIUM AND INTEREST.

               Notwithstanding any other provision in this Indenture, the Holder
of any Debenture shall have the right, which is absolute and unconditional, to
receive payment of the Accreted Value of (and premium, if any) and (subject to
Section 307) interest on such Debenture on the respective Stated Maturities
expressed in such Debenture (or, in the case of redemption, on the Redemption
Date or in the case of an Asset Sale Offer or Change of Control Offer made by
the Company and required to be accepted as to such Debenture, on the Purchase
Date) and to institute suit for the enforcement of any such payment, and such
rights shall not be impaired without the consent of such Holder.


                                       65
<PAGE>

SECTION 509.   RESTORATION OF RIGHTS AND REMEDIES.

               If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.


SECTION 510.   RIGHTS AND REMEDIES CUMULATIVE.

               Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Debentures in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.


SECTION 511.   DELAY OR OMISSION NOT WAIVER.

               No delay or omission of the Trustee or of any Holder of any
Debenture to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein. Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by the Holders,
as the case may be.


SECTION 512.   CONTROL BY HOLDERS.

               The Holders of a majority in aggregate principal amount at
maturity of the Outstanding Debentures shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee, PROVIDED that

               (1) such direction shall not be in conflict with any rule of law
        or with this Indenture or involve the Trustee in personal liability, and

                                       66
<PAGE>

               (2) the Trustee may take any other action deemed proper by the
        Trustee which is not inconsistent with such direction.


SECTION 513.   WAIVER OF PAST DEFAULTS.

               The Holders of not less than a majority in aggregate principal
amount at maturity of the Outstanding Debentures may on behalf of the Holders of
all the Debentures waive any existing Default hereunder and its consequences,
except a default with respect to any provision requiring a supermajority to
amend, which default may only be waived by such a supermajority, except a
Default

               (1) in the payment of the Accreted Value of (or premium, if any)
        or interest on any Debenture (including any Debenture which is required
        to have been purchased pursuant to an Asset Sale Offer or Change of
        Control Offer which has been made by the Company), or

               (2) in respect of a covenant or provision hereof which under
        Article Nine cannot be modified or amended without the consent of the
        Holder of each Outstanding Debenture affected.

               Upon any such waiver, such Default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or impair any right consequent thereon.

SECTION 514.   UNDERTAKING FOR COSTS.

               In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs,
including reasonable attorney's fees and expenses, against any such party
litigant, in the manner and to the extent provided in the Trust Indenture Act;
PROVIDED, that neither this Section nor the Trust Indenture Act shall be deemed
to authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Trustee or the Company.

SECTION 515.   WAIVER OF USURY, STAY OR EXTENSION LAWS.

               The Company covenants (to the extent that it may lawfully do so)
that it shall not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any usury, stay or extension law
wherever enacted, now or at any time hereafter in force, which may affect the
covenants or the performance of this Indenture; and the Company (to the extent
that it may lawfully do so) hereby expressly waives all benefit or advantage of
any such law and covenants that it shall not hinder, delay or impede the
execution of any power herein granted to the Trustee, but shall suffer and
permit the execution of every such power as though no such law had been enacted.


                                   ARTICLE SIX

                                   The Trustee

SECTION 601.   CERTAIN DUTIES AND RESPONSIBILITIES.

               (a) The duties and responsibilities of the Trustee shall be as
        provided by the Trust Indenture Act. Notwithstanding the foregoing, no
        provision of this Indenture shall require the Trustee to expend or risk
        its own funds or otherwise incur any financial liability in the
        performance of any of its duties hereunder, or in the exercise of any of
        its rights or powers, if it shall have reasonable grounds for believing
        that repayment of such funds or adequate indemnity against such risk or
        liability is not reasonably assured to it. Whether or not therein
        expressly so provided, every provision of this Indenture relating to the
        conduct or affecting the liability of or affording protection to the
        Trustee shall be subject to the provisions of this Section.

               (b) Except during the continuance of a Default or an Event of
Default:

                      (1) The Trustee need undertake to perform only those
                      duties as are specifically set forth in this Indenture and
                      no covenants or obligations shall be implied in this
                      Indenture against the Trustee.

                      (2) In the absence of bad faith on its part, the Trustee
                      may conclusively rely, as to the truth of the statements
                      and the correctness of the opinions expressed therein,
                      upon certificates or opinions furnished to the Trustee and
                      conforming to the requirements of this Indenture. However,
                      the Trustee shall examine the certificates and opinions to
                      determine whether or not they conform to the requirements
                      of this Indenture.

                                       68
<PAGE>

               (c) The Trustee shall have no liability except for its own
        negligent action, its own negligent failure to act, or its own willful
        misconduct, except that:

                      (1) This paragraph does not limit the effect of paragraph
                      (b) of this Section 601.

                      (2) The Trustee shall not be liable for any error of
                      judgment made in good faith by a Responsible Officer,
                      unless it is proved that the Trustee was negligent in
                      ascertaining the pertinent facts.

                      (3) The Trustee shall not be liable with respect to any
                      action it takes or omits to take in good faith in
                      accordance with a direction received by it pursuant to
                      Section 512.


SECTION 602.   NOTICE OF DEFAULTS.

               If a Default or Event of Default occurs and is continuing and if

                      (2) the Trustee shall cease to be eligible under Section
        609 and shall fail to resign after written request therefor by the
        Company or by any such Holder, or

                      (3) the Trustee shall become incapable of acting or shall

               (e) If the Trustee shall resign, be removed or become incapable
of acting, or if a vacancy shall occur in the office of Trustee for any cause,
the Company, by a Board Resolution, shall promptly appoint a successor Trustee.
If, within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount at maturity of the Outstanding
Debentures delivered to the Company and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment,
become the successor Trustee and supersede the successor Trustee appointed by
the Company. If no successor Trustee shall have been so appointed by the Company
or the Holders and accepted appointment in the manner hereinafter provided, any
Holder who has been a bona fide Holder of a Debenture for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee.

accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; but, on request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder. Upon request of any such successor
Trustee, the Company shall execute any and all instruments for more fully and

business of the Trustee, shall be the successor of the Trustee hereunder,

Article, without the execution or filing of any paper or any further act on the

authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Debentures so authenticated with the same
effect as if such successor Trustee had itself authenticated such Debentures.


SECTION 613.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

against the Company (or any such other obligor).

               It shall not be necessary for any Act of Holders under this
Section to approve the particular form of any proposed supplemental indenture,
but it shall be sufficient if such Act shall approve the substance thereof.


SECTION 903.   EXECUTION OF SUPPLEMENTAL INDENTURES.

               In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.


SECTION 904.   EFFECT OF SUPPLEMENTAL INDENTURES.

               Upon the execution of any supplemental indenture under this
Article, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes; and
every Holder theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.


SECTION 905.   CONFORMITY WITH TRUST INDENTURE ACT.

               Every supplemental indenture executed pursuant to this Article
shall conform to the requirements of the Trust Indenture Act.

               Debentures authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Debentures so modified as to conform, in the opinion of the Trustee and the
Company, to any such supplemental indenture may be prepared and executed by the
Company and authenticated and delivered by the Trustee in exchange for
Outstanding Debentures.

SECTION 907.   AMENDMENTS AT THE REQUEST OF HOLDERS.

               Notwithstanding any provision herein to the contrary, if the
Initial Purchasers holding not less than a majority in aggregate principal
amount at maturity of the Outstanding Debentures notify the Company that such
Holders intend to sell or otherwise transfer at least a majority in aggregate
principal amount at maturity of the Outstanding Debentures, the Company will, if
requested by such Holders, negotiate in good faith with such Holders to amend
any provision herein to reflect terms that are contained in similar types of
indebtedness as the Debentures of similarly situated companies being issued at
or about the time of such request.


                                   ARTICLE TEN

                                    Covenants

SECTION 1001.  PAYMENT OF ACCRETED VALUE, PREMIUM AND INTEREST.

               The Company shall duly and punctually pay the Accreted Value of
(and premium, if any) and any interest on the Debentures in accordance with the
terms of the Debentures and this Indenture.


SECTION 1002.  MAINTENANCE OF OFFICE OR AGENCY.

               The Company shall maintain in the Borough of Manhattan, The City
of New York, an office or agency where Debentures may be presented or
surrendered for payment, where Debentures may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company in
respect of the Debentures and this Indenture may be served. The Company shall
give prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee, and the
Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

               The Company may also from time to time designate one or more
other offices or agencies (in or outside the Borough of Manhattan, The City of
New York) where the Debentures may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; PROVIDED,
HOWEVER, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, The City of New York, for such purposes. The Company shall give
prompt written


                                       82
<PAGE>

notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.


SECTION 1003.  MONEY FOR DEBENTURE PAYMENTS TO BE HELD IN TRUST.

               If the Company shall at any time act as its own Paying Agent, it
shall, on or before each due date of the Accreted Value of (and premium, if any)
or interest on any of the Debentures, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum sufficient to pay the Accreted
Value (and premium, if any) or interest so becoming due until such sums shall be
paid to such Persons or otherwise disposed of as herein provided and shall
promptly notify the Trustee of its action or failure so to act.

               Whenever the Company shall have one or more Paying Agents, it
shall, prior to each due date of the Accreted Value of (and premium, if any) or
interest on any Debentures, deposit with a Paying Agent a sum sufficient to pay
the Accreted Value (and premium, if any) or interest so becoming due, such sum
to be held in trust for the benefit of the Persons entitled to such Accreted
Value, premium, interest, and (unless such Paying Agent is the Trustee) the
Company shall promptly notify the Trustee of its action or failure so to act.

               The Company shall cause each Paying Agent other than the Trustee
to execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent shall:

               (1)    hold all sums held by it for the payment of the Accreted
                      Value of (and premium, if any) or interest on Debentures
                      in trust for the benefit of the Persons entitled thereto
                      until such sums shall be paid to such Persons or otherwise
                      disposed of as herein provided;

               (2)    give the Trustee notice of any Default by the Company (or
                      any other obligor upon the Debentures) in the making of
                      any payment of Accreted Value (and premium, if any) or
                      interest; and

               (3)    at any time during the continuance of any such Default,
                      upon the written request of the Trustee, forthwith pay to
                      the Trustee all sums so held in trust by such Paying
                      Agent.

               The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.


                                       83
<PAGE>

               Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the Accreted Value of (and
premium, if any) or interest on any Debenture and remaining unclaimed for two
years after such Accreted Value (and premium, if any) or interest has become due
and payable shall be paid to the Company on Company Request, or (if then held by
the Company) shall be discharged from such trust; and the Holder of such
Debenture shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; PROVIDED, HOWEVER, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in The City of New York, notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money then
remaining shall be repaid to the Company.


SECTION 1004.  EXISTENCE.

               Subject to Article Eight and Section 1015, the Company and its
Restricted Subsidiaries shall do or cause to be done all things necessary to
preserve and keep in full force and effect their existence, rights (charter and
statutory) and franchises; PROVIDED, HOWEVER, that the Company and its
Restricted Subsidiaries shall not be required to preserve any such right or
franchise if the Board of Directors of the Company in good faith shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company or its Restricted Subsidiaries and that the loss thereof
is not disadvantageous in any material respect to the Holders.


SECTION 1005.  MAINTENANCE OF PROPERTIES.

               The Company shall cause all properties used or useful in the
conduct of its business or the business of any Restricted Subsidiary of the
Company to be maintained and kept in good condition, repair and working order
and supplied with all necessary equipment and shall cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof,
all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly and advantageously conducted
at all times; PROVIDED, HOWEVER, that nothing in this Section shall prevent the
Company from discontinuing the operation or maintenance of any of such
properties if such discontinuance is, as determined by the Board of Directors of
the Company in good faith, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect to
the Holders.

                                       84
<PAGE>

SECTION 1006.  PAYMENT OF TAXES AND OTHER CLAIMS.

               The Company shall pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (1) all taxes, assessments
and governmental charges levied or imposed upon the Company or any of its
Restricted Subsidiaries or upon the income, profits or property of the Company
or any of its Restricted Subsidiaries, and (2) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a lien upon the
property of the Company or any of its Restricted Subsidiaries; PROVIDED,
HOWEVER, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings or would not result in a material adverse effect on the Company.


SECTION 1007.  MAINTENANCE OF INSURANCE.

               The Company shall, and shall cause its Restricted Subsidiaries
to, keep at all times all of their properties which are of an insurable nature
insured against loss or damage with insurers believed by the Company to be
responsible or in the case of insurance coverage, to self-insure, in each case
to the extent, in the judgment of the Company, to do so comports with good
business practice.


SECTION 1008.  LIMITATION ON INCURRENCE OF INDEBTEDNESS
               AND ISSUANCE OF PREFERRED STOCK.

               The Company shall not, and shall not permit any of its
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Debt) and the Company shall not issue any Disqualified Stock or preferred stock
and shall not permit any of its Restricted Subsidiaries to issue any
Disqualified Stock or preferred stock, PROVIDED, HOWEVER, that the Company may
incur Indebtedness (including Acquired Debt) or issue Disqualified Stock or
preferred stock and the Company's Restricted Subsidiaries may incur Indebtedness
(including Acquired Debt) and issue Disqualified Stock or preferred stock if the
Fixed Charge Coverage Ratio for the Company's most recently ended four full
fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is incurred
or such Disqualified Stock or preferred stock is issued would have been at least
1.75 to 1, determined on a PRO FORMA basis (including a PRO FORMA application of
the net proceeds therefrom), as if the additional Indebtedness had been
incurred, or the Disqualified Stock or preferred stock had been issued, as the
case may be, at the beginning of such four-quarter period.

(collectively, "Permitted Debt"):

               (l)    the incurrence by the Company or any of its Restricted

                      obligations, in each case incurred for the purpose of
                      financing all or any part of the purchase price or cost of
                      construction or improvement of property, plant or
                      equipment used in the business of the Company or such
                      Restricted Subsidiary (whether through the direct purchase
                      of assets or the Capital Stock of any Person owning such
                      Assets), in an aggregate principal amount or accreted
                      value, as applicable, not to exceed $15 million at any

                      Indenture to be incurred under the first paragraph of this
                      covenant or clauses (14) or (15) of this Section 1008;

               (6)    the incurrence by the Company or any of its Restricted
                      Subsidiaries of intercompany Indebtedness between or among
                      the Company and any of its Restricted Subsidiaries;
                      PROVIDED, HOWEVER, that:

                      (a)    if the Company is the obligor on such Indebtedness,
                             such Indebtedness must be expressly subordinated to
                             the prior payment

                             Company or a Wholly Owned Restricted Subsidiary
                             shall be deemed, in each case, to constitute an
                             incurrence of such Indebtedness by the Company
                             or such Restricted Subsidiary, as the case may
                             be, that was not permitted by this clause (6);

               (7)    the incurrence by the Company or any of its Restricted

               (9)    the incurrence by the Company's Unrestricted Subsidiaries
                      of Non-Recourse Debt; provided, however, that if any such
                      Indebtedness ceases to be Non-Recourse Debt of an
                      Unrestricted Subsidiary, such event shall be deemed to
                      constitute an incurrence of Indebtedness by a Restricted
                      Subsidiary of the Company that was not permitted by this
                      clause (9);

                      Restricted Subsidiary providing for indemnification,

                      disposition of any business, asset or Subsidiary, other
                      than guarantees of Indebtedness incurred by any Person
                      acquiring all or any portion of such business, assets or
                      Subsidiary for the purpose of financing such acquisition;
                      provided that (a) such Indebtedness is not reflected on
                      the balance sheet of the Company or any Restricted
                      Subsidiary (contingent obligations referred to in a
                      footnote or footnotes to financial statements and not
                      otherwise reflected on the balance sheet shall not be
                      deemed to be reflected on such balance sheet for purposes
                      of this clause (a) and (b) the maximum aggregate liability
                      in respect of such Indebtedness shall at no time exceed

                      market value of such non-cash proceeds being measured at
                      the time received and without giving effect to any such
                      subsequent changes in value) actually received by the
                      Company and/or such Restricted Subsidiary in connection

               (13)   Indebtedness arising from the honoring by a bank or other
                      financial institution of a check, draft or similar
                      instrument (except in the case of daylight overdrafts)
                      drawn against insufficient funding in the ordinary course
                      of business, PROVIDED, HOWEVER, that such Indebtedness is

                      Subsidiaries of additional Indebtedness, including
                      Attributable Debt incurred after the Issue Date, in an
                      aggregate principal amount (or accreted value, as
                      applicable) at any time outstanding, including all
                      Permitted Refinancing Indebtedness incurred to refund,
                      refinance or replace any other Indebtedness incurred
                      pursuant to this clause (14), not to exceed $25 million;
                      and

               (15)   the incurrence by the Company of Indebtedness represented
                      by the Debentures.

               For purposes of determining compliance with this Section 1008, in
the event that an item of proposed Indebtedness meets the criteria of more than
one of the categories of Permitted Debt described in clauses (1) through (15)
above or is entitled to be incurred pursuant to the first paragraph of this
covenant, the Company shall be permitted to classify such item of Indebtedness
in any manner that complies with this covenant. In addition, the Company may, at
any time, change the classification of an item of Indebtedness (or any portion
thereof) to any


                                       88

other clause or to the first paragraph hereof provided that the Company would be
permitted to incur such item of Indebtedness (or the portion thereof) pursuant
to such other clause or the first paragraph hereof, as the case may be, at such
time of reclassification. Accrual of interest, accretion or amortization of
original issue discount and the accretion of accreted value shall not be deemed
to be an incurrence of Indebtedness for purposes of this covenant.

               (2)    purchase, redeem or otherwise acquire or retire for value
                      (including without limitation, in connection with any
                      merger or consolidation involving the Company) any Equity
                      Interests of the Company or any direct or indirect parent
                      of the Company or any Restricted Subsidiary of the Company
                      (other than any such Equity Interests owned by the Company
                      or any Restricted Subsidiary of the Company);

               (3)    make any payment on or with respect to, or purchase,
                      redeem, defease or otherwise acquire or retire for value
                      any Indebtedness that is subordinated to the Debentures,
                      except scheduled payments of interest or principal at
                      Stated Maturity thereof; or

               (4)    make any Restricted Investment (all such payments and
                      other actions set forth in clauses (1) through (4) above
                      being collectively referred to as "Restricted Payments"),

unless, at the time of and after giving effect to such Restricted Payment:

               (1)    no Default or Event of Default shall have occurred and be
                      continuing or would occur as a consequence thereof;

               (2)    the Company would, after giving PRO FORMA effect thereto
                      as if such Restricted Payment had been made at the
                      beginning of the applicable four-quarter period, have been
                      permitted to incur at least $1.00 of additional
                      Indebtedness pursuant to the Fixed Charge Coverage Ratio
                      test set forth in the first paragraph of Section 1008; and

               (3)    such Restricted Payment, together with the aggregate
                      amount of all other Restricted Payments made by the
                      Company and its Restricted Subsidiaries after the Issue
                      Date (excluding Restricted Payments permitted by clauses
                      (1) through (6) and (11) and (12) of the next succeeding
                      paragraph), is less than the sum, without duplication, of:

                             quarter commencing after the Issue Date to the end
                             of the Company's most recently ended fiscal
                             quarter for which internal financial statements
                             are available at the time of such Restricted
                             Payment (or, if such Consolidated Net Income for
                             such period is a deficit, less 100% of such
                             deficit); plus

                             to the Company's capital or received by the

                      shall be included in subsequent calculations of the amount
                      of Restricted Payments;

the fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any non-cash Restricted Payment shall be determined in good
faith by the Board of Directors of the Company whose resolution with respect
thereto shall be delivered to the Trustee. The Board of Directors' determination
must be based upon an opinion or appraisal issued by an accounting, appraisal or
investment banking firm of national standing if such fair market value exceeds
$20 million. Not later than the date of making any Restricted Payment, the
Company shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the
calculations required by this Section 1009 were computed, together with a copy
of any fairness opinion or appraisal required by this Indenture.

               RESTRICTED SUBSIDIARIES.

encumbrances or restrictions existing under or by reason of:

                      effect at or entered into on the Issue Date, including:

                             more restrictive, taken as a whole (as determined
                             in the good faith judgment of the Company's Board
                             of Directors), with respect to such dividend and

                      a Person acquired by the Company or any of its Restricted
                      Subsidiaries as in effect at the time of such acquisition
                      (except to the extent incurred in connection with or in
                      contemplation of such acquisition), which encumbrance or
                      restriction is not applicable to any Person, or the
                      properties or assets of any Person, other than the Person,
                      or the property or assets of the Person, so

                      acquired, PROVIDED THAT, in the case of Indebtedness,
                      such Indebtedness was permitted by the terms of this
                      Indenture to be incurred;

               (4)    customary non-assignment provisions in leases entered into
                      in the ordinary course of business and consistent with
                      past practices;

               (5)    any Purchase Money Note or other Indebtedness or
                      contractual requirements incurred with respect to a
                      Qualified Receiveables Transaction relating exclusively to
                      a Receiveables Entity that, in the good faith
                      determination of the Board of Directors of the Company,
                      are necessary to effect such Qualified Receiveables
                      Transaction;

               (6)    purchase money obligations for property acquired in the
                      ordinary course of business that impose restrictions on
                      the property so acquired of the nature described in the
                      last clause of the preceding paragraph;

               (7)    restrictions with respect solely to a Restricted
                      Subsidiary of the Company imposed pursuant to a binding
                      agreement which has been entered into for the sale or
                      disposition of all or substantially all of the Capital
                      Stock or assets of such Restricted Subsidiary, provided
                      that such restrictions apply solely to the Capital Stock
                      or assets being sold of such Restricted Subsidiary;

               (8)    provisions with respect to the disposition or distribution
                      of assets or property in connection with Permitted Joint
                      Ventures entered into in accordance with past practice
                      made in the ordinary course of business;

               (9)    Permitted Refinancing Indebtedness, provided that the
                      material restrictions contained in the agreements
                      governing such Permitted Refinancing Indebtedness are no
                      more restrictive, in the good faith judgment of the
                      Company's Board of Directors, taken as a whole, to the
                      Holders than those contained in the agreements governing
                      the Indebtedness being refinanced; and

               (10)   restrictions on cash or other deposits or net worth

                      ordinary course of business.

               Notwithstanding the foregoing, neither (a) customary provisions
restricting subletting or assignment of any lease entered into in the ordinary
course of business, consistent with industry practice, nor (b) Liens permitted
under the terms of this Indenture shall in and of themselves be considered a
restriction on the ability of the applicable Restricted Subsidiary to transfer
such agreement or assets, as the case may be.

SECTION 1011.  LIMITATION ON LIENS SECURING INDEBTEDNESS.

               The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or
become effective any Lien of any kind securing trade payables, Attributable Debt
or Indebtedness (other than Permitted Liens) upon any of their property or
assets, now owned or hereafter acquired unless:

               (1)    in the case of Liens securing Indebtedness that is
                      expressly subordinated or junior in right of payment to
                      the Debentures, the Debentures are secured on a senior
                      basis to the obligations so secured until such time as
                      such obligations are no longer secured by a Lien; and

               (2)    in all other cases, the Debentures are secured on an equal
                      and ratable basis with the obligations so secured until
                      such time as such obligations are no longer secured by a
                      Lien.


SECTION 1012.  LIMITATION ON TRANSACTIONS WITH AFFILIATES.

               The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate or any affiliated professional associations or professional
corporations which employ physicians and other professionals who provide
healthcare services for the Company's occupational and health services centers
(each, an "Affiliate Transaction"), unless:

               (1)    such Affiliate Transaction is on terms that are no less
                      favorable to the Company or the relevant Restricted
                      Subsidiary than those that would have been obtained in a
                      comparable transaction by the Company or such Restricted
                      Subsidiary made on an arm's-length basis with an unrelated
                      Person; and

               (2)    the Company delivers to the Trustee:

                      (a)    with respect to any Affiliate Transaction or series
                             of related Affiliate Transactions involving
                             aggregate consideration in excess of $5 million, a
                             resolution of the Board of Directors of the
                             Company set forth in an Officers' Certificate
                             certifying that such Affiliate Transaction
                             complies with clause (1) above and that such


                                       96
<PAGE>

                             Affiliate Transaction has been approved by a
                             majority of the disinterested members of the Board
                             of Directors; and

                      (b)    with respect to any Affiliate Transaction or series
                             of related Affiliate Transactions involving
                             aggregate consideration in excess of $15 million,

                             such Affiliate Transaction from a financial point
                             of view issued by an accounting, appraisal or
                             investment banking firm of national standing.

               The following items shall not be deemed to be Affiliate
Transactions and, therefore, shall not be subject to the provisions of the prior
paragraph:

               (1)    customary directors' fees to Persons who are not otherwise
                      Affiliates of the Company;

                      financing, underwriting or placement services or in
                      respect of other investment banking activities, including,

                      a majority of the Board of Directors of the Company or a
                      committee thereof consisting of disinterested members;

               (5)    loans or advances to employees in accordance with past
                      practice made in the ordinary course of business which are
                      approved in good faith by a majority of the Board of
                      Directors of the Company or a committee thereof consisting
                      of disinterested members;

               (6)    any agreement as in effect on the Issue Date or any
                      amendment thereto (so long as any such amendment is no
                      less favorable to the Company and its Restricted
                      Subsidiaries);

               (7)    the existence of, or the performance by the Company or any
                      of its Restricted Subsidiaries of its obligations under
                      the terms of, the Merger Agreement (including any

                      the Issue Date and any similar agreements which it
                      may enter into thereafter; PROVIDED, HOWEVER, that
                      the existence of, or the performance by the Company
                      or any of its Restricted Subsidiaries of obligations
                      under any future amendment to any such existing
                      agreement or under any similar agreement entered into
                      after the Issue Date shall only be permitted by this
                      clause;

               (9)    any payment pursuant to any tax sharing agreement between
                      the Company and any other Person with which the Company is
                      required or permitted to file a consolidated tax return or
                      with which the Company is or could be part of a
                      consolidated, combined or unitary group for tax purposes;
                      PROVIDED that in no event shall the amount permitted to be
                      paid pursuant to all such agreements exceed the tax
                      liabilities attributable solely to the Company and its
                      Restricted Subsidiaries (whether as a consolidated,

                      banking, merchant banking, commercial banking or related
                      activities.

               Notwithstanding the foregoing, the Holders will be entitled to
receive payment in full in cash of all amounts due or to become due in respect
of the Debentures before any payment is made with respect to Affiliate
Management Fees in the event of any distribution to creditors of the Company in
any Insolvency or Liquidation Proceeding with respect to the Company. No
payments of Affiliate Management Fees shall be made by the Company or any of its
Restricted Subsidiaries if the Fixed Charge Coverage Ratio for the Company's
most recently ended four full fiscal quarters for which internal financial
statements are available immediately preceding the date on which Affiliate
Management Fees are to be paid is less than 1.5 to 1; PROVIDED, HOWEVER, that
such payments due but not paid shall accrue and shall be paid only after such
time as the Fixed Charge Coverage Ratio for a four full fiscal quarter period is
no longer less than or equal to 1.5 to 1.

                      a Receivables Entity); or

               (2)    in compliance with Section 1015 and immediately after
                      giving effect to such issuance or sale, such Restricted
                      Subsidiary would continue to be a Restricted Subsidiary.

               Notwithstanding the preceding paragraph, the Company may sell all
the Equity Interests of a Restricted Subsidiary as long as the Company complies
with Section 1015.

SECTION        1014. REPURCHASE OF DEBENTURES AT THE OPTION OF THE HOLDER
               UPON A CHANGE OF CONTROL.

               (1) Upon the occurrence of a Change of Control, each Holder shall
have the right to require the Company to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of such Holder's Debentures pursuant to
the offer described below (the "Change of Control Offer") at an offer price in
cash equal to 101% of the Accreted Value thereof on any Redemption Date plus,
after the Full Accretion Date, accrued and unpaid interest thereon, if any, to
the Purchase Date (the "Change of Control Payment"). Within 60 Business Days
following any Change of Control, the Company shall mail a notice to each Holder
stating:

               (a)    that the Change of Control Offer is being made pursuant to
                      this Section 1014 and that all Debentures tendered shall
                      be accepted for payment;

               (b     that the Change of Control Offer shall remain open for 20
                      Business Days;

               (c)    the Purchase Price and the Purchase Date;

               (d)    that any Debenture not tendered shall continue to accrue
                      interest;

               (e)    that, unless the Company defaults in the payment of the
                      Change of Control Payment, all Debentures accepted for
                      payment pursuant to the Change of Control Offer shall
                      cease to accrue interest after the Purchase Date;

                                       99
<PAGE>

               (f)    that Holders electing to have any Debentures purchased
                      pursuant to a Change of Control Offer shall be required to
                      surrender the Debentures, with the form entitled "Option
                      of Holder to Elect Purchase" on the reverse of the
                      Debentures completed, to the Paying Agent at the address
                      specified in the notice prior to the close of business on
                      the third Business Day preceding the Purchase Date;

               (g)    that Holders shall be entitled to withdraw their election
                      if the Paying Agent receives, not later than the close of
                      business on the second Business Day preceding the Purchase
                      Date, a telegram, telex, facsimile transmission or letter
                      setting forth the name of the Holder, the principal amount
                      at maturity of Debentures delivered for purchase, and a
                      statement that such Holder is withdrawing his election to
                      have the Debentures purchased; and

               (h)    that Holders whose Debentures are being purchased only in
                      part shall be issued new Debentures equal in principal
                      amount at maturity to the unpurchased portion of the
                      Debentures surrendered, which unpurchased portion must be
                      equal to $1,000 in principal amount at maturity or an
                      integral multiple thereof.

               The Company shall comply with the requirements of Rule 14e-1
under the Exchange Act and any other securities laws and regulations thereunder
to the extent such laws and regulations are applicable in connection with the
repurchase of the Debentures as a result of a Change of Control.

               To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Indenture relating to such
Change of Control Offer, the Company shall comply with the applicable securities
laws and regulations and shall not be deemed to have breached its obligations
described in this Indenture by virtue thereof.

               (2) By 12:00 p.m. (noon) Eastern Time on the Purchase Date, the
Company shall, to the extent lawful:

               (a)    accept for payment all Debentures or portions thereof
                      properly tendered pursuant to the Change of Control Offer;

               (b)    deposit with the Paying Agent an amount equal to the
                      Change of Control Payment in respect of all Debentures or
                      portions thereof so tendered; and

               (c)    deliver or cause to be delivered to the Trustee the
                      Debentures so accepted together with an Officers'
                      Certificate stating the aggregate Accreted Value of
                      Debentures or portions thereof being purchased by the
                      Company.

                                      100
<PAGE>

               The Paying Agent shall promptly mail to each Holder of Debentures
so tendered the Change of Control Payment for such Debentures, and the Trustee
shall promptly authenticate and mail (or cause to be transferred by book entry)
to each Holder a new Debenture equal in principal amount at maturity to any
unpurchased portion of the Debentures surrendered, if any; provided that each
such new Debenture shall be in a principal amount at maturity of $1,000 or an
integral multiple thereof. The Company shall publicly announce the results of
the Change of Control Offer on or as soon as practicable after the Purchase
Date.

               (3) Prior to making a Change of Control Offer pursuant to
paragraph (a), but in any event within 90 days following such Change of Control,
the Company shall (i) obtain any required consents, if any, under all agreements
governing outstanding Senior Indebtedness to permit the making of the Change of
Control Offer and the purchase of Debentures pursuant to this Section 1014, or
(ii) repay all or a portion of the outstanding Senior Indebtedness to the extent
necessary (including, if necessary, payment in full of such Senior Indebtedness
and payment of any prepayment premiums, fees, expenses or penalties) to permit
the repurchase of the Notes pursuant to this Section 1015 without such consent.

               (4) Notwithstanding anything to the contrary in this Section
1014, the Company shall not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in this Section 1014 hereof and all other provisions of this Indenture
applicable to a Change of Control Offer made by the Company and purchases all
Debentures validly tendered and not withdrawn under such Change of Control
Offer.


SECTION 1015.  REPURCHASE OF DEBENTURES AT THE OPTION OF THE HOLDER UPON AN
ASSET SALE.

               The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless:

               (1)    the Company (or the Restricted Subsidiary, as the case may
                      be) receives consideration at the time of such Asset Sale
                      at least equal to the fair market value of the assets or
                      Equity Interests issued or sold or otherwise disposed of;

               (2)    such fair market value is determined by the Company's
                      Board of Directors and evidenced by a resolution of the
                      Board of Directors set forth in an Officers' Certificate
                      delivered to the Trustee provided that the Board of
                      Directors' determination must be based on an opinion or
                      appraisal issued by an accounting, appraisal or investment
                      banking firm of national standing if such fair market
                      value exceeds $35 million; and

                                      101
<PAGE>

               (3)    at least 75% of the consideration therefor received by the
                      Company or such Restricted Subsidiary is in the form of
                      cash or Cash Equivalents. For purposes of this provision,
                      each of the following shall be deemed to be cash:

                      (a)    any liabilities (as shown on the Company's or the
                             Restricted Subsidiary's most recent balance sheet)
                             of the Company or any Restricted Subsidiary (other
                             than contingent liabilities and liabilities that
                             are by their terms subordinated to the Debentures,
                             that are assumed by the transferee of any such
                             assets pursuant to a customary novation agreement
                             that releases the Company or such Restricted
                             Subsidiary from further liability; and

                      (b)    any securities, notes or other obligations received
                             by the Company or any such Restricted Subsidiary
                             from such transferee that are contemporaneously
                             (subject to ordinary settlement periods) converted
                             by the Company or such Restricted Subsidiary into
                             cash or Cash Equivalents (to the extent of the cash
                             received in that conversion).

               The 75% limitation referred to above shall not apply to any Asset
Sale in which the cash or Cash Equivalents portion of the consideration received
therefrom, determined in accordance with the preceding sentence, is equal to or
greater than what the after-tax proceeds would have been had such Asset Sale
complied with the 75% limitation.

               Within 270 days after the receipt of any Net Proceeds from an
Asset Sale, the Company or any such Restricted Subsidiary may apply such Net
Proceeds, at its option:

               (1)    to repay or repurchase Senior Indebtedness of the Company
                      or Indebtedness of any Restricted Subsidiary;

               (2)    to acquire all or substantially all the assets of, or a
                      majority of the Voting Stock of, another Permitted
                      Business;

               (3)    to make a capital expenditure in a Permitted Business;

               (4)    to acquire other assets (other than securities) that are
                      used or useful in a Permitted Business; or

               (5)    to make an Asset Sale Offer, treating the Net Proceeds as
                      Excess Proceeds for all purposes.

                                      102
<PAGE>

               Any Net Proceeds from Asset Sales that are not applied or
invested as provided in the preceding paragraph shall constitute "Excess
Proceeds". When the aggregate amount of Excess Proceeds exceeds $15 million, the
Company shall be required to make an offer to all Holders of Debentures (an
"Asset Sale Offer") to purchase the maximum Accreted Value of Debentures that
may be purchased out of the Excess Proceeds. The offer price in any Asset Sale
Offer shall be equal to 100% of the Accreted Value thereof on any Redemption
Date plus, after the Full Accretion Date, accrued and unpaid interest, if any,
to the Purchase Date, and shall be payable in cash. If any Excess Proceeds
remain after consummation of an Asset Sale Offer, the Company may use such
Excess Proceeds for general corporate purposes. If the aggregate Accreted Value
of Debentures tendered into such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Trustee shall select the Debentures to be purchased on a pro rata
basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds
shall be reset at zero.

               To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Indenture relating to such
Asset Sale Offer, the Company shall comply with the applicable securities laws
and regulations and shall not be deemed to have breached its obligations
described in this Indenture by virtue thereof.

SECTION 1016.  INVESTMENT COMPANY.

               The Company shall not, and shall not permit any of its
Subsidiaries to, be required to register as an "Investment Company" (as that
term is defined in the Investment Company Act of 1940, as amended), or otherwise
become subject to registration under the Investment Company Act.


SECTION 1017.  LIMITATION ON LINES OF BUSINESS.

               The Company shall not, and shall not permit any Restricted
Subsidiary to, engage in any business other than a Permitted Business.


SECTION 1018.  SALE AND LEASEBACK TRANSACTIONS.

               The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; provided that
the Company or any Restricted Subsidiary may enter into a sale and leaseback
transaction if:

               (1)    the Company or such Restricted Subsidiary could have (a)
                      incurred Indebtedness in an amount equal to the
                      Attributable Debt relating to such sale and leaseback
                      transaction under the Fixed Charge Coverage Ratio test

                                      103
<PAGE>

                      in the first paragraph of Section 1008 and (b) incurred a
                      Lien to secure such Indebtedness pursuant to Section 1011;

               (2)    the gross cash proceeds of that sale and leaseback
                      transaction are at least equal to the fair market value,
                      as determined in good faith by the Board of Directors of
                      the Company and set forth in an Officers' Certificate
                      delivered to the Trustee, of the property that is the
                      subject of such sale and leaseback transaction; and

               (3)    the transfer of assets in such sale and leaseback
                      transaction is permitted by, and the Company applies the
                      proceeds of such transaction in compliance with Section
                      1015.

SECTION 1019.  DESIGNATION OF RESTRICTED AND UNRESTRICTED SUBSIDIARIES.

               The Board of Directors of the Company may designate any
Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would
not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted
Subsidiary, all outstanding Investments owned by the Company and its Restricted
Subsidiaries (except to the extent repaid in cash) in the Subsidiary so
designated shall be deemed to be Restricted Payments at the time of such
designation (to the extent not designated a Permitted Investment) and shall
reduce the amount available for Restricted Payments under the first paragraph of
Section 1009. All such outstanding Investments shall be valued at their fair
market value at the time of such designation, as determined in good faith by the
Board of Directors of the Company. That designation shall only be permitted if
such Restricted Payment would be permitted at that time and if such Restricted
Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The
Board of Directors of the Company may redesignate any Unrestricted Subsidiary to
be a Restricted Subsidiary if the redesignation would not cause a Default.


SECTION 1020.  ADVANCES OF SUBSIDIARIES.

               All advances to Restricted Subsidiaries made by the Company after
the Issue Date shall be evidenced by intercompany notes in favor of the Company
in the form of Exhibit C. Each intercompany note shall be payable upon demand
and shall bear interest at the same rate as the Debentures.


                                      104
<PAGE>

SECTION 1021.  PAYMENTS FOR CONSENTS.

               The Company shall not, and shall not permit any of its
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any Holder for or as an inducement to any
consent, waiver or amendment of any of the terms or provisions of this Indenture
or the Debentures unless such consideration is offered to be paid and is paid to
all Holders that consent, waive or agree to amend in the time frame set forth in
the solicitation documents relating to such consent, waiver or agreement.


SECTION 1022.  STATEMENT BY OFFICERS AS TO DEFAULT; COMPLIANCE CERTIFICATES.

               (a) The Company shall deliver to the Trustee, within 90 days
after the end of each fiscal year an Officers' Certificate, stating whether or
not to the best knowledge of the signers thereof the Company is in default in
the performance and observance of any of the terms, provisions and conditions of
Section 801 or Sections 1004 to 1021, inclusive, and if the Company shall be in
default, specifying all such Defaults and the nature and status thereof of which
they may have knowledge.

               (b) The Company shall deliver to the Trustee, as soon as possible
and in any event within 10 days after the Company becomes aware or should
reasonably become aware of the occurrence of a Default or an Event of Default,
an Officers' Certificate setting forth the details of such Default or Event of
Default, and the action which the Company proposes to take with respect thereto.

               (c) So long as not contrary to the then current provisions of the
American Institute of Certified Public Accountants, the Company shall deliver to
the Trustee within 90 days after the end of each fiscal year a written statement
by the Company's independent public accountants stating (A) that their audit
examination has included a review of the terms of this Indenture and the
Debentures as they relate to accounting matters, and (B) whether, in connection
with their audit examination, any Default has come to their attention and, if
such a Default has come to their attention, specifying the nature and period of
the existence thereof.

SECTION 1023.  WAIVER OF COVENANTS.

               The Company may omit in any particular instance to comply with
any covenant or condition set forth in Section 801 and Sections 1004 to 1021, if
before the time for such compliance the Holders of at least a majority in
principal amount at maturity of the Outstanding Debentures shall, by Act of such
Holders, either waive such compliance in such instance or generally waive
compliance with such covenant or condition, but no such waiver shall extend to
or affect such covenant or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Company
and the duties of the Trustee in respect of any such covenant or condition shall
remain in full force and effect; PROVIDED, HOWEVER, with respect to any
provision requiring a supermajority approval to waive, such provision may only
be waived by such a supermajority, and with respect to a covenant or provision
which cannot be modified or amended without the consent of the Holder of each
outstanding Debenture affected, such provision may only be waived by the consent
of each and every Holder of outstanding Debenture affected.

                      to be redeemed, and in the case of partial redemption, a
                      statement as the effect that upon surrender of such

                      maturity equal to the unredeemed portion thereof shall be
                      issued upon cancellation of the original Debenture,

               (4)    that on the Redemption Date the Redemption Price shall
                      become due and payable upon each such Debenture to be
                      redeemed, and

               (5)    the place or places where such Debentures are to be
                      surrendered for payment of the Redemption Price.

               Notice of redemption of Debentures to be redeemed at the election
of the Company shall be given by the Company or, at the Company's request, by
the Trustee in the name and at the expense of the Company if the Company gives
notice to the Trustee at least 45 days prior to the Redemption Date.

               Notices of redemption may not be conditional.


SECTION 1106.  DEPOSIT OF REDEMPTION PRICE.

               Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) any applicable accrued interest on, all
the Debentures which are to be redeemed on that date. The Trustee or the Paying
Agent shall promptly return to the Company any money deposited with the Trustee
or the Paying Agent by the Company in excess of the amounts necessary to pay the
Redemption Price of, and any applicable accrued interest on, all Debentures to
be redeemed.


SECTION 1107.  DEBENTURES PAYABLE ON REDEMPTION DATE.

               Notice of redemption having been given as aforesaid, the
Debentures so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date
(unless the Company shall default in the payment of the Redemption Price and any
applicable accrued interest) such Debentures or portions of them called for
redemption shall not bear interest. Upon surrender of any such Debenture for
redemption in accordance with said notice, such Debenture shall be paid by the
Company at the Redemption Price, together with any applicable accrued interest
to the Redemption Date; PROVIDED, HOWEVER, that installments of interest whose
Interest Payment Date is on or prior to the Redemption Date shall be payable to
the Holders of such Debentures, or one or more Predecessor Debentures,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.

               If any Debenture called for redemption shall not be so paid upon
surrender thereof for redemption, the Accreted Value(and premium, if any) shall,
until paid, bear interest, if any, from the Redemption Date at the rate provided
by the Debenture.

SECTION 1108.  DEBENTURES REDEEMED IN PART.

               Any Debenture which is to be redeemed only in part shall be
surrendered at an office or agency of the Company designated for that purpose
pursuant to Section 1002 (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Debenture without service
charge, a new Debenture or Debentures, of any authorized denomination as
requested by such Holder, in aggregate principal amount at maturity equal to and
in exchange for the unredeemed portion of the principal of the Debenture so
surrendered.

SECTION 1201.  COMPANY'S OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT
DEFEASANCE.

               The Company may, at its option and at any time, by Board
Resolution elect to have either Section 1202 or 1203 hereof be applied with
respect to the Outstanding Debentures upon compliance with the conditions set
forth below in this Article Twelve.


SECTION 1202.  LEGAL DEFEASANCE AND DISCHARGE.

               Upon the Company's exercise of the option provided in Section
1201 applicable to this Section, the Company shall be deemed to have been
discharged from its obligations with respect to the Outstanding Debentures on
the date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, such Legal Defeasance means that the Company
shall be deemed to have paid and discharged the entire indebtedness represented
by the Outstanding Debentures and to have satisfied all its other obligations
under such Debentures and this Indenture insofar as such Debentures are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except as to (i) rights of Holders to
receive payments in respect of the Accreted Value of, premium, if any, and
interest on such Debentures when such payments are due from the trust funds;
(ii) the Company's obligations with respect to such Debentures concerning
Sections 304, 305, 306, 1002 and 1003; (iii) the rights, powers, trust, duties,
and immunities of the Trustee, and the Company's


                                      110
<PAGE>

obligations in connection therewith; and (iv) the Legal Defeasance provisions of
this Article Twelve, all of which shall survive until otherwise terminated or
discharged hereunder. Subject to compliance with this Article Twelve, the
Company may exercise its option under this Section 1202 notwithstanding the
prior exercise of its option under Section 1203.

SECTION 1203.  COVENANT DEFEASANCE.

               Upon the Company's exercise of the option provided in Section
1201 applicable to this Section, the Company may, at its option and at any time,
elect to have the obligations of the Company released with respect to its (i)
obligations under Sections 1005 through 1021, inclusive, and clause (4) of
Section 801 and (ii) the occurrence of an event specified in Sections 501(4),
(with respect to any of Sections 1005 through 1021, inclusive), 501(5) and
501(6) shall not be deemed to be a Default, an Event of Default on and after the
date the conditions set forth below are satisfied (hereinafter, "Covenant
Defeasance"). For this purpose, such Covenant Defeasance means that the Company
may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such Section or clause, whether
directly or indirectly by reason of any reference elsewhere herein to any such
Section or clause or by reason of any reference in any such Section or clause to
any other provision herein or in any other document, but the remainder of this
Indenture and such Debentures shall be unaffected thereby.


SECTION 1204.  CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

               The following shall be the conditions to application of either
Section 1202 or Section 1203 to the then Outstanding Debentures:

               (1) The Company shall irrevocably have deposited or caused to be
        deposited with the Trustee as trust funds in trust for the purpose of
        making the following payments, specifically pledged as security for, and
        dedicated solely to, the benefit of the Holders of such Debentures, in
        U.S. dollars, non-callable Government Securities, or a combination
        thereof, in such amounts as shall be sufficient, in the opinion of a
        nationally recognized firm of independent public accountants, to pay the
        Accreted Value of, premium, if any, and interest on the Outstanding
        Debentures on the Stated Maturity or on the applicable Redemption Date,
        as the case may be, and the Company must specify whether the Debentures
        are being defeased to maturity or to a particular Redemption Date;

               (2) In the case of an election of Legal Defeasance under Section
        1202, the Company shall have delivered to the Trustee an Opinion of
        Counsel in the United States reasonably acceptable to the Trustee
        confirming that (a) the Company has received from, or there has been
        published by, the Internal Revenue Service a ruling or (b) since the
        Issue Date, there has been a change in the applicable federal income tax
        law, in either case to the effect that, and based thereon such Opinion
        of Counsel shall confirm that,



                                      111
<PAGE>

       subject to customary assumptions and exclusions, the Holders of the
       Outstanding Debentures shall not recognize income, gain or loss for
       federal income tax purposes as a result of such Legal Defeasance and
       shall be subject to federal income tax on the same amounts, in the same
       manner and at the same times as would have been the case if such Legal
       Defeasance had not occurred;

              (3) In the case of an election of Covenant Defeasance under
       Section 1203, the Company shall have delivered to the Trustee an Opinion
       of Counsel in the United States reasonably acceptable to the Trustee
       confirming that, subject to customary assumptions and exclusions, the
       Holders of the Outstanding Debentures shall not recognize income, gain
       or loss for federal income tax purposes as a result of such Covenant
       Defeasance and shall be subject to federal income tax on the same
       amounts, in the same manner and at the same times as would have been the
       case if such Covenant Defeasance had not occurred;

              (4) no Default or Event of Default shall have occurred and be
       continuing on the date of such deposit (other than a Default or Event of
       Default resulting from the borrowing of funds to be applied to such
       deposit);

              (5) such Legal Defeasance or Covenant Defeasance shall not result
       in a breach or violation of, or constitute a default under, any material
       agreement or instrument (other than this Indenture) to which the Company
       or any of its Subsidiaries is a party or by which the Company or any of
       its Subsidiaries is bound;

              (6) the Company must deliver to the Trustee an Officers'
       Certificate stating that the deposit was not made by the Company with
       the intent of preferring the Holders over the other creditors of the
       Company or with the intent of defeating, hindering, delaying or
       defrauding creditors of the Company or others;

              (7) no event which is, or after notice or lapse of time or both
       would become, an Event of Default with respect to such Debentures or any
       other Debentures shall have occurred and be continuing at the time of
       such deposit or, with regard to any such event specified in paragraphs
       (7) or (8) of Section 501, at any time on or prior to the 90th day after
       the date of such deposit (it being understood that this condition shall
       not be deemed satisfied until after such 90th day); and

              (8) The Company shall have delivered to the Trustee an Officers'
       Certificate and an Opinion of Counsel, which opinion may be subject to
       customary assumptions and exclusions, each stating that all conditions
       precedent provided for relating to either the Legal Defeasance under
       Section 1202 or the Covenant Defeasance under Section 1203 (as the case
       may be) have been complied with.

SECTION 1205.  DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE
                      HELD IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

               Subject to the provisions of the last paragraph of Section 1003,
all money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee (or other qualifying trustee--collectively, for
purposes of this Section 1205, the "Trustee") pursuant to Section 1204 in
respect of the Debentures shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Debentures and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Holders of
such Debentures, of all sums due and to become due thereon in respect of
Accreted Value (and premium, if any) and interest, but such money need not be
segregated from other funds except to the extent required by law.

               The Company shall pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 1204 or the Accreted Value and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the Outstanding
Debentures.

               Anything in this Article Twelve to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1204 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.


SECTION 1206.  REINSTATEMENT.

               If the Trustee or the Paying Agent is unable to apply any money
in accordance with Section 1202 or 1203 by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, or if a Default from a bankruptcy or insolvency
event occurs at any time during the period ending on the 91st day after the date
of a deposit by the Company hereunder, then the Company's obligations under this
Indenture and the Debentures shall be revived and reinstated as though no
deposit had occurred pursuant to this Article Twelve until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with
Section 1202 or 1203; PROVIDED, HOWEVER, that if the Company makes any payment
of Accreted Value of (and premium, if any) or interest on any Debenture
following the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Debentures to receive such payment from the
money held by the Trustee or the Paying Agent.

No.                          $_________(principal amount at maturity)

               Concentra Managed Care, Inc., a corporation duly organized and
existing under the laws of Delaware (herein called the "Company", which term
includes any successor Person under the Indenture hereinafter referred to), for
value received, hereby promises to pay to _________________, or registered
assigns, the principal sum of _______________ million dollars on August 15,
2010, and to pay interest semi-annually in arrears of each Interest Payment
Date, or if any such day is not a Business Day, on the next succeeding Business
Day, commencing on February 15, 2005. The Debentures will not bear or accrue
cash interest until August 15, 2004. Cash interest on the Debentures will accrue
from the most recent date to which interest has been paid or, if no interest has
been paid, from August 15, 2004 at the rate of 14% per annum. The Company shall
make each interest payment to the holders of record on the immediately preceding
February 1 and August 1 until the principal amount at maturity thereof is paid
or made available for payment, and at the rate of 15% per annum on any overdue
principal at maturity and premium, if any, and on any overdue installment of
interest, if any, until paid.

               On any Interest Payment Date after the Full Accretion Date, the
Company shall pay such amount of accrued original discount on the Debentures as
shall be necessary to ensure that the Debenture shall not be considered an
"applicable high yield discount obligation" with the meaning of Section 163(i)
of the Internal Revenue Code of 1986, as amended, or any successor provision. On
February 15, 2005 and on each subsequent Interest Payment Date, the Accreted
Value of the Debenture shall be reduced by the amount of accrued original issue
discount required to be paid on such Debenture pursuant to the immediately
preceding sentence. In the event of any such payment of accrued original issue
discount, the Accreted Value of the Debenture shall be further reduced as of its
maturity date to the extent necessary to ensure that the yield to maturity on
the Debenture (determined as provided in Section 1272 of the Code and the
regulations thereunder and computed by taking into account any such payment of
accrued original issue discount) shall equal the yield to maturity on this
Debenture (computed as though no such payment of accrued original discount had
been paid).

               Payment of the Accreted Value of (and premium, if any) and
interest on this Debenture will be made at the office or agency of the Company
maintained for that purpose in the Borough of Manhattan, The City of New York,
in such coin or currency of the United States of America as at the time of
payment is legal tender for payment of public and private debts; PROVIDED,
HOWEVER, that at the option of the Company payment of interest may be made by

        1      This Table of Contents does not constitute a part of this
               Agreement or have any bearing upon the interpretation of any of
               its terms or provisions.

<PAGE>


               WARRANT AGREEMENT (the "Warrant Agreement" or this "Agreement")
dated as of August 17, 1999 (the "Issue Date") between Concentra Managed Care,
Inc., a Delaware corporation (the "Company"), and the parties named herein
(together with their successors and assigns, the "Holders").

               Terms defined in the Securities Purchase Agreement (the
"Securities Purchase Agreement") dated as of August 17, 1999 between the Company
and the purchasers named therein (the "Initial Purchasers") unless defined
herein are used as therein defined.

               WHEREAS, the Company proposes to issue Warrants, as hereinafter
described (the "Warrants"), to purchase up to 1,595,406 shares of Common Stock
(the "Common Stock") of the Company (the Common Stock issuable on exercise of
the Warrants being referred to herein as the "Warrant Shares"), in connection
with a private placement of an aggregate of $216,230,000 principal amount of the
Company's Senior Discount Debentures due 2010 (the "Debentures") and each
Warrant entitling the Holder thereof to purchase one Warrant Share.

               NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereto agree as follows:

               SECTION 1. WARRANT CERTIFICATES. The certificates evidencing the
Warrants (the "Warrant Certificates") to be delivered pursuant to this Agreement
shall be in registered form only and shall be substantially in the form set
forth in Exhibit A attached hereto.

               SECTION 2. EXECUTION OF WARRANT CERTIFICATES. Warrant
Certificates shall be signed on behalf of the Company by its Chairman of the
Board or its Chief Executive Officer or its President or its Chief Operating
Officer or its Chief Financial Officer or a Vice President and by its Secretary
or an Assistant Secretary under its corporate seal. Each such signature upon the
Warrant Certificates may be in the form of a facsimile signature of the present
or any future Chairman of the Board, Chief Executive Officer, President, Chief
Operating Officer, Chief Financial Officer, Vice President, Secretary or
Assistant Secretary and may be imprinted or otherwise reproduced on the Warrant
Certificates and for that purpose the Company may adopt and use the facsimile
signature of any person who shall have been Chairman of the Board, Chief
Executive Officer, President, Chief Operating Officer, Chief Financial Officer,
Vice President, Secretary or Assistant Secretary, notwithstanding the fact that
at the time the Warrant Certificates shall be delivered or disposed of he shall
have ceased to hold such office. The seal of the Company may be in the form of a
facsimile thereof and may be impressed, affixed, imprinted or otherwise
reproduced on the Warrant Certificates.

               In case any officer of the Company who shall have signed any of
the Warrant Certificates shall cease to be such officer before the Warrant
Certificates so signed shall have been disposed of by the Company, such Warrant
Certificates nevertheless may be delivered or disposed of as though such person
had not ceased to be such officer of the Company; and any Warrant Certificate
may be signed on behalf of the Company by any person who, at the actual

<PAGE>

date of the execution of such Warrant Certificate, shall be a proper officer of
the Company to sign such Warrant Certificate, although at the date of the
execution of this Warrant Agreement any such person was not such an officer.

               SECTION 3. REGISTRATION. The Company shall number and register
the Warrant Certificates in a register as they are issued. The Company may deem
and treat the registered Holder(s) of the Warrant Certificates as the absolute
owner(s) thereof (notwithstanding any notation of ownership or other writing
thereon made by anyone), for all purposes, and shall not be affected by any
notice to the contrary. The Company shall act as the registrar for the Warrants.

               SECTION 4. REGISTRATION OF TRANSFERS AND EXCHANGES. (a) The
Company shall from time to time register the transfer of any outstanding Warrant
Certificates in a Warrant register to be maintained by the Company upon
surrender thereof accompanied by the Assignment Form on the reverse of the
Warrant Certificate, duly executed by the registered Holder or Holders thereof
or by the duly appointed legal representative thereof or by a duly authorized
attorney together with such legal opinions, certificates or other information
required by such Assignment Form. Upon any such registration of transfer, a new
Warrant Certificate shall be issued to the transferee(s) and the surrendered
Warrant Certificate shall be canceled and disposed of by the Company.

               (b) The Holders agree that each Warrant Certificate and any
certificate representing the Warrant Shares will bear the following legend (the
"Private Placement Legend"):

               "THIS SECURITY (OR ITS PREDECESSOR) (AND, IF SUCH SECURITY
EVIDENCES A WARRANT, THE WARRANT SHARES ISSUABLE PURSUANT THERETO) HAS NOT BEEN
REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE
TRANSFERRED WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF,
U.S. PERSONS, EXCEPT AS SET FORTH IN THE NEXT SENTENCE. BY ITS ACQUISITION
HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE HOLDER:

               (1)    AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS
                      SECURITY EXCEPT (A) TO THE COMPANY OR ANY OF ITS
                      SUBSIDIARIES, (B) TO A PERSON WHOM THE SELLER REASONABLY
                      BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED
                      IN RULE 144A UNDER THE SECURITIES ACT) (A "QIB")
                      PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QIB
                      IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A,
                      (C) IN AN OFFSHORE TRANSACTION MEETING THE REQUIREMENTS OF
                      RULE 903 OR 904 OF THE SECURITIES ACT, (D) IN A
                      TRANSACTION MEETING

                                       2
<PAGE>

                      THE REQUIREMENTS OF RULE 144 UNDER THE SECURITIES ACT,
                      (E) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE
                      REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND
                      BASED UPON AN OPINION OF COUNSEL ACCEPTABLE TO THE
                      COMPANY) OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION
                      STATEMENT AND, IN EACH CASE, IN ACCORDANCE WITH THE
                      APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED
                      STATES OR ANY OTHER APPLICABLE JURISDICTION, AND

               (2)    AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS
                      SECURITY OR AN INTEREST HEREIN IS TRANSFERRED A NOTICE
                      SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.

                      AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION" AND
                      "UNITED STATES" HAVE THE MEANINGS GIVEN TO THEM BY RULE
                      902 OF REGULATION S UNDER THE SECURITIES ACT.

               (c) The Holders agree that each Warrant Certificate issued during
the period such Warrants are subject to the restrictions in the Stockholders
Agreement of the Company dated August 17, 1999 (the "Stockholders Agreement")
shall bear the following legend (the "Stockholders Agreement Legend"):

        THE SECURITY REPRESENTED BY THIS CERTIFICATE IS ALSO SUBJECT TO CERTAIN
        RESTRICTIONS ON TRANSFERABILITY CONTAINED IN THE STOCKHOLDERS AGREEMENT
        DATED AS OF AUGUST 17, 1999, A COPY OF WHICH IS ON FILE AT THE COMPANY'S
        PRINCIPAL EXECUTIVE OFFICES.

               (d) Subject to the foregoing provisions, Warrant Certificates may
be exchanged at the option of the Holder(s) thereof, when surrendered to the
Company at its office for another Warrant Certificate or other Warrant
Certificates of like tenor and representing in the aggregate a like number of
Warrants. Upon any sale or transfer of any Warrant Certificate or Warrant Shares
pursuant to an effective registration statement under the Securities Act or
satisfying the condition set forth in clause (1)(D) of the above Private
Placement Legend, the Company shall permit the Holder thereof to exchange such
Warrant Certificate or such Warrant Shares for another Warrant Certificate or
certificate evidencing Warrant Shares, as applicable, that does not bear the
Private Placement Legend set forth above. At any time after the time that the
Warrants are not subject to the restrictions on transfer set forth in the
Stockholders Agreement, the Company shall permit the Holder thereof to exchange
such Warrant Certificate for another Warrant Certificate that does not bear the
Stockholders Agreement Legend. Warrant Certificates surrendered for exchange
shall be canceled and disposed of by the Company.


                                       3
<PAGE>

               (e) Each Holder of a Warrant Certificate, by accepting the same,
consents and agrees with the Company and with each subsequent holder of such
Warrant Certificate that, prior to due presentment of such Warrant Certificate
for registration of transfer, the Company may treat the person in whose name the
Warrant Certificate is registered as the owner thereof for all purposes and as
the person entitled to exercise the rights granted under the Warrants, and
neither the Company nor any agent thereof shall be affected by any notice to the
contrary.

               SECTION 5. WARRANTS; EXERCISE OF WARRANTS. Subject to the terms
of this Agreement, each Holder shall have the right, which may be exercised
commencing at the opening of business on the Exercisability Date and until 5:00
p.m., New York City time on August 15, 2010, to receive from the Company the
number of fully paid and nonassessable Warrant Shares and any other capital
stock of the Company issuable upon exercise of the Warrant as provided for in
Section 10(a) ("Additional Warrant Shares") which the Holder may at the time be
entitled to receive on exercise of such Warrants and payment of the Exercise
Price then in effect for such Warrant Shares; provided, however, that Holders
will be able to exercise their Warrants only if (i) a registration statement
relating to the Warrant Shares is effective or (ii) the exercise of such
Warrants is exempt from the registration requirements of the Securities Act (and
the Company has received such information as the Company may reasonably request
to confirm that such transfer is being made pursuant to an exemption from, or in
a transaction not subject to, the registration requirements of the Securities
Act). Each Warrant not exercised prior to 5:00 p.m., New York City time, on
August 15, 2010 shall become void and all rights thereunder and all rights in
respect thereof under this agreement shall cease as of such time. The
"Exercisability Date" shall be the earlier of (i) the second anniversary of the
Issue Date and (ii) the date following the sale by the Initial Purchasers of
more than 50% of the outstanding Debentures.

               A Warrant may be exercised upon surrender to the Company at its
office designated for such purpose (the address of which is set forth in Section
14 hereof) of the Warrant Certificate or Certificates evidencing the Warrants to
be exercised with the form of election to purchase on the reverse thereof duly
filled in and signed, which signature shall be guaranteed by a bank or trust
company having an office or correspondent in the United States or a broker or
dealer which is a member of a registered securities exchange or the National
Association of Securities Dealers, Inc., and upon payment to the Company of the
exercise price (the "Exercise Price") which is set forth in the form of Warrant
Certificate attached hereto as Exhibit A as adjusted as herein provided, for the
number of Warrant Shares and Additional Warrant Shares, if any, in respect of
which such Warrants are then exercised. Payment of the aggregate Exercise Price
shall be made in cash or by certified or official bank check to the order of the
Company. In lieu of exercising a Warrant by paying in full the Exercise Price
plus transfer taxes (if applicable pursuant to Section 6), if any, the Holder
may, from time to time, convert a Warrant, in whole or in part, into a number of
shares of Common Stock determined by dividing (a) the aggregate current market
price of the number of shares of Common Stock represented by the Warrants
converted, minus the aggregate Exercise Price for such shares of Common Stock,

                                       4
<PAGE>

minus transfer taxes, if any, by (b) the current market price of one share of
Common Stock (a "Cash-Less Exercise"). The current market price shall be
determined pursuant to Section 10(f).

               Subject to the provisions of Section 6 hereof, upon such
surrender of Warrant Certificates and payment of the Exercise Price (if such
exercise is not a Cash-Less Exercise) the Company shall issue and cause to be
delivered with all reasonable dispatch (and in any event within five Business
Days after such receipt) to or upon the written order of the Holder and, subject
to Section 4, in such name or names as the Holder may designate, a certificate
or certificates for the number of full Warrant Shares and Additional Warrant
Shares, if any, issuable upon the exercise of such Warrants together with cash
as provided in Section 11; PROVIDED, HOWEVER, that if any consolidation, merger
or lease or sale of assets is proposed to be effected by the Company as
described in subsection (k) of Section 10 hereof, or a tender offer or an
exchange offer for shares of Common Stock of the Company shall be made, upon
such surrender of Warrant Certificates and payment of the Exercise Price as
aforesaid (if such exercise is not a Cash-Less Exercise), the Company shall, as
soon as possible, but in any event not later than two business days thereafter,
issue and cause to be delivered the full number of Warrant Shares and Additional
Warrant Shares, if any, issuable upon the exercise of such Warrants in the
manner described in this sentence together with cash, if any, as provided in
Section 11. Such certificate or certificates shall be deemed to have been issued
and any person so designated to be named therein shall be deemed to have become
a holder of record of such Warrant Shares and Additional Warrant Shares, if any,
as of the date of the surrender of such Warrant Certificates and payment of the
Exercise Price (if such exercise is not a Cash-Less Exercise).

               Prior to the exercise of the Warrants, except as may be
specifically provided for herein, (i) no Holder of a Warrant Certificate, as
such, shall be entitled to any of the rights of a holder of Common Stock of the
Company, including, without limitation, the right to vote at or to receive any
notice of any meetings of stockholders; (ii) the consent of any such Holder
shall not be required with respect to any action or proceeding of the Company;
(iii) except as provided in Section 10(i), no such Holder, by reason of the
ownership or possession of a Warrant or the Warrant Certificate representing the
same, shall have any right to receive any cash dividends, stock dividends,
allotments or rights or other distributions paid, allotted or distributed or
distributable to the stockholders of the Company prior to, or for which the
relevant record date preceded, the date of the exercise of such Warrant; and
(iv) no such Holder shall have any right not expressly conferred by the Warrant
or Warrant Certificate held by such Holder.

               The Warrants shall be exercisable, at the election of the Holders
thereof, either in full or from time to time in part and, in the event that a
Warrant Certificate is exercised in respect of fewer than all of the Warrant
Shares issuable on such exercise at any time prior to the date of expiration of
the Warrants, a new Warrant Certificate evidencing the remaining Warrant or
Warrants will be issued and delivered pursuant to the provisions of this Section
and of Section 2 hereof.

               All Warrant Certificates surrendered upon exercise of Warrants
shall be canceled and disposed of by the Company. The Company shall keep copies
of this Agreement and any

                                       5
<PAGE>
notices given or received hereunder available for inspection by the Holders
during normal business hours at its office.

               Notwithstanding anything contained herein to the contrary, no
Warrant shall be exercisable by any Regulated Warrantholder and no Warrant
Shares shall be issued to any Regulated Warrantholder if, after giving effect to
such exercise, issuance or action, such Regulated Warrantholder would own more
than 4.99% of any class of voting securities of the Company (other than any
class of voting securities which is (or is made prior to any such exercise,
issuance or action) convertible into a class of non-voting securities which are
otherwise identical to the voting securities and convertible into such voting
securities on terms reasonably acceptable to such Regulated Warrantholder) or
more than 24.99% of the total equity of the Company or more than 24.99% of the
total value of all capital stock and subordinated debt of the Company (in each
case determined by assuming such Regulated Warrantholder (but no other holder)
has exercised, converted or exchanged all of its options, warrants and other
convertible or exchangeable securities). For purposes of this paragraph,
"REGULATED WARRANTHOLDER" shall mean Chase Equity Associates, L.P. or any other
Holder that (i) is subject to the provisions of Regulation Y of the Board of
Governors of the Federal Reserve System, 12 C.F.R. Part 225 (or any successor to
such Regulation), (ii) holds Warrants or shares of Common Stock and (iii) has
provided written notice of the Company of its status as a "Regulated
Stockholder" hereunder.

               SECTION 6. PAYMENT OF TAXES. The Company will pay all documentary
stamp taxes attributable to the initial issuance of Warrant Shares and
Additional Warrant Shares, if any, upon the exercise of Warrants; PROVIDED,
HOWEVER, that the Company shall not be required to pay any tax or taxes which
may be payable in respect of any transfer involved in the issue of any Warrant
Certificates or any certificates for Warrant Shares or Additional Warrant
Shares, if any, in a name other than that of the registered Holder of a Warrant
Certificate surrendered for registration of transfer or upon the exercise of a
Warrant, and the Company shall not be required to issue or deliver such Warrant
Certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to the reasonable satisfaction of the Company that such tax has been
paid.

               SECTION 7. MUTILATED OR MISSING WARRANT CERTIFICATES. In case any
of the Warrant Certificates shall be mutilated, lost, stolen or destroyed, the
Company may in its discretion issue, in exchange and substitution for and upon
cancellation of the mutilated Warrant Certificate, or in lieu of and
substitution for the Warrant Certificate lost, stolen or destroyed, a new
Warrant Certificate of like tenor and representing an equivalent number of
Warrants, but only upon receipt of evidence reasonably satisfactory to the
Company of such loss, theft or destruction of such Warrant Certificate and
indemnity, if requested, also reasonably satisfactory to it. Applicants for such
substitute Warrant Certificates shall also comply with such other reasonable
regulations and pay such other reasonable charges as the Company may prescribe.

               SECTION 8. RESERVATION OF WARRANT SHARES. The Company will at all
times reserve and keep available, free from preemptive rights, out of the
aggregate of its authorized but unissued Common Stock or other capital stock of
the class with respect to Additional Warrant

                                       6
<PAGE>

Shares, if any, or its authorized and issued Common Stock or other capital stock
of the class with respect to Additional Warrant Shares, if any, held in its
treasury, for the purpose of enabling it to satisfy any obligation to issue
Warrant Shares and Additional Warrant Shares, if any, upon exercise of Warrants,
the maximum number of shares of Common Stock and other capital stock with
respect to Additional Warrant Shares, if any, which may then be deliverable upon
the exercise of all outstanding Warrants.

               The Company or, if appointed, the transfer agent for the Common
Stock (the "Transfer Agent") and every subsequent transfer agent for any shares
of the Company's capital stock issuable upon the exercise of any of the rights
of purchase aforesaid will be irrevocably authorized and directed at all times
to reserve such number of authorized shares as shall be required for such
purpose. The Company will keep a copy of this Agreement on file with the
Transfer Agent and with every subsequent transfer agent for any shares of the
Company's capital stock issuable upon the exercise of the rights of purchase
represented by the Warrants. The Company will furnish such Transfer Agent a copy
of all notices of adjustments and certificates related thereto, transmitted to
each Holder pursuant to Section 12 hereof.

               Before taking any action which would cause an adjustment pursuant
to Section 10 hereof to reduce the Exercise Price below the then par value (if
any) of the Warrant Shares, the Company will take any corporate action which
may, in the opinion of its counsel (which may be counsel employed by the
Company), be necessary in order that the Company may validly and legally issue
fully paid and nonassessable Warrant Shares at the Exercise Price as so
adjusted.

               The Company represents and warrants that the initial Warrant
Shares issuable upon conversion of Warrants have been duly authorized and
covenants that all Warrant Shares and Additional Warrant Shares, if any, which
may be issued upon exercise of Warrants will, upon issue, be fully paid,
nonassessable, free of preemptive rights (other than as set forth in the
Stockholders Agreement) and, subject to Section 6, free from all taxes, liens,
charges and security interests with respect to the issue thereof.
`
               SECTION 9. OBTAINING STOCK EXCHANGE LISTINGS. The Company will
from time to time take all action which may be necessary so that the Warrant
Shares and the Additional Warrant Shares, if any, immediately upon their
issuance upon the exercise of Warrants, will be listed on the principal
securities exchanges and markets within the United States of America, if any, on
which other shares of Common Stock or the Additional Warrant Shares, if any, as
the case may be, are then listed.

               SECTION 10. ADJUSTMENT OF NUMBER OF WARRANT SHARES ISSUABLE. The
number of Warrant Shares issuable upon the exercise of each Warrant are subject
to adjustment from time to time upon the occurrence of the events enumerated in
this Section 10. For purposes of this Section 10, "Common Stock" means shares
now or hereafter authorized of any class of common stock of the Company and any
other stock of the Company, however designated, that

                                       7
<PAGE>

has the right (subject to any prior rights of any class or series of preferred
stock) to participate in any distribution of the assets or earnings of the
Company without limit as to per share amount.

               (a)    ADJUSTMENT FOR CHANGE IN CAPITAL STOCK.

               If the Company:

               (1) pays a dividend or makes a distribution on its Common Stock
        in shares of its Common Stock;

               (2) subdivides its outstanding shares of Common Stock into a
        greater number of shares;

               (3) combines its outstanding shares of Common Stock into a
        smaller number of shares;

               (4) makes a distribution on its Common Stock in shares of its
        capital stock other than Common Stock; or

               (5) issues by reclassification of its Common Stock any shares of
        its capital stock;

then the number and kind of shares of its capital stock issuable upon exercise
of any Warrant in effect immediately prior to such action shall be
proportionately adjusted so that the Holder of any Warrant thereafter exercised
may receive the aggregate number and kind of shares of capital stock of the
Company which he or she would have owned immediately following such action if
such Warrant had been exercised immediately prior to such action.

               The adjustment shall become effective immediately after the
record date in the case of a dividend or distribution and immediately after the
effective date in the case of a subdivision, combination or reclassification.

               If, after an adjustment, a Holder of a Warrant upon exercise of
it may receive shares of two or more classes of capital stock of the Company,
the exercise privilege of each class of capital stock shall thereafter be
subject to adjustment on terms comparable to those applicable to Common Stock in
this Section.

               Such adjustment shall be made successively whenever any event
listed above shall occur.

               (b)    ADJUSTMENT FOR RIGHTS ISSUE.

                                       8
<PAGE>

               If the Company distributes any rights, options or warrants to all
holders of its Common Stock entitling them for a period expiring within 45 days
after the record date mentioned below to purchase shares of Common Stock or
securities directly or indirectly convertible into or exchangeable for Common
Stock (or options or rights with respect to such securities) at a price per
share less than the current market price per share on that record date, the
number of Warrant Shares issuable upon exercise of one Warrant shall be adjusted
in accordance with the formula:


                      N' = N x  (O + A)
                              --------------
                                (O + (A x P))
                                          -
                                          M

where:

        N' = the adjusted number of Warrant Shares issuable upon exercise of one
             Warrant.

        N = the current number of Warrant Shares issuable upon exercise of one
            Warrant.

        O = the number of shares of Common Stock outstanding on the record date.

        A = the number of additional shares of Common Stock offered pursuant to
            such rights issuance.

        P = the offering price per share of the additional shares.

        M = the current market price per share of Common Stock on the record
            date.

               The adjustment shall be made successively whenever any such
rights, options or warrants are issued and shall become effective immediately
after the record date for the determination of stockholders entitled to receive
the rights, options or warrants. If at the end of the period during which such
rights, options or warrants are exercisable, not all rights, options or warrants
shall have been exercised, the number of Warrant Shares issuable upon exercise
of the Warrants shall be immediately readjusted to what it would have been if
the shares represented by "A" in the above formula had been the number of shares
actually issued.

               (c)    ADJUSTMENT FOR OTHER DISTRIBUTIONS.

               If the Company distributes to all holders of its Common Stock any
of its assets (including but not limited to cash), debt securities, or any
rights or warrants to purchase debt securities, assets or other securities of
the Company, the number of Warrant Shares issuable upon exercise of one Warrant
shall be adjusted in accordance with the formula:

                                       9
<PAGE>

                      N' = N x  M
                               ----
                                M-F

where:

               N' = the adjusted number of Warrant Shares issuable upon
                    exercise of one Warrant.

               N  = the current number of Warrant Shares issuable upon
                    exercise of one Warrant.

               M  = the current market price per share of Common Stock on
                    the record date mentioned below.

               F  = the fair market value on the record date of the assets,
                    securities, rights or warrants applicable to one share of
                    Common Stock. The Board of Directors shall determine the
                    fair market value in good faith.

               The adjustment shall be made successively whenever any such
distribution is made and shall become effective immediately after the record
date for the determination of stockholders entitled to receive the distribution.

               No adjustment shall be made pursuant to this subsection (c) if
the fair market value on the applicable record date of the assets, securities,
rights or warrants applicable to one share of Common Stock is equal to or
greater than the current market price per share of Common Stock on such record
date.

               This subsection does not apply to rights, options or warrants
referred to in subsection (b) of this Section 10.

               (d)    ADJUSTMENT FOR COMMON STOCK ISSUE.

               If the Company issues shares of Common Stock for a consideration
per share less than the current market price per share on the date the Company
fixes the offering price of such additional shares, the number of Warrant Shares
issuable upon exercise of one Warrant shall be adjusted in accordance with the
formula:

                      N' = N  x  A
                               -----
                               O + P
                                   -
                                   M

where:

        N' = the adjusted number of Warrant Shares issuable upon exercise of one
             Warrant.

                                       10
<PAGE>

        N  = the then current number of Warrant Shares issuable upon
               exercise of one Warrant.

        O  = the number of shares outstanding immediately prior to the
             issuance of such additional shares.

        P  = the aggregate consideration received for the issuance of such
             additional shares.

        M  = the current market price per share on the date of sale of such
             additional shares.

        A  = the number of shares outstanding immediately after the issuance
             of such additional shares.

             The adjustment shall be made successively whenever any such
issuance is made, and shall become effective immediately after such issuance.

             This subsection (d) does not apply to:

             (1)  any of the transactions described in subsections (b) and (c)
        of this Section 10,

             (2) the exercise of Warrants, or the conversion or exchange of
        other securities convertible or exchangeable for Common Stock,

             (3) Common Stock issued upon the exercise of warrants and stock
        options outstanding on the Issue Date, or

             (4) Common Stock issued in a bona fide public offering pursuant
        to a firm commitment underwriting.

             (e)    ADJUSTMENT FOR CONVERTIBLE SECURITIES ISSUE.

             If the Company issues any securities convertible into or
exchangeable for Common Stock (other than securities issued in transactions
described in subsections (b) and (c) of this Section 10) for a consideration per
share of Common Stock initially deliverable upon conversion or exchange of such
securities less than the current market price per share on the date of issuance
of such securities, the number of Warrant Shares issuable upon exercise of one
Warrant shall be adjusted in accordance with this formula:


                      N' = N  x  O + D
                                 -----
                                 O + P
                                     -
                                     M

                                       11
<PAGE>

where:

        N' = the adjusted number of Warrant Shares issuable upon exercise of one
Warrant.

        N  = the then current number of Warrant Shares issuable upon
             exercise of one Warrant.

        O  = the number of shares outstanding immediately prior to the
             issuance of such securities.

        P  = the aggregate consideration received for the issuance of such
             securities.

        M  = the current market price per share on the date of sale of such
             securities.

        D  = the maximum number of shares deliverable upon conversion or in
             exchange for such securities at the initial conversion or
             exchange rate.

             The adjustment shall be made successively whenever any such
issuance is made, and shall become effective immediately after such issuance.

             If all of the Common Stock deliverable upon conversion or
exchange of such securities have not been issued when such securities are no
longer outstanding, then the number of Warrant Shares issuable upon exercise of
one Warrant shall promptly be readjusted to the number of Warrant Shares
issuable upon exercise of one Warrant which would then be in effect had the
adjustment upon the issuance of such securities been made on the basis of the
actual number of shares of Common Stock issued upon conversion or exchange of
such securities.

             This subsection (e) does not apply to convertible securities
issued in a bona fide public offering pursuant to a firm commitment
underwriting.

             (f)    CURRENT MARKET PRICE.

             In Sections 5 and 11 and in subsections (b), (c), (d) and (e) of
this Section 10 the current market price per share of Common Stock on any date
is the average of the Quoted Prices of the Common Stock for 30 consecutive
trading days commencing 45 trading days before the date in question. The "Quoted
Price" of the Common Stock is the last reported sales price of the Common Stock
as reported by NASDAQ, National Market System, or if the Common Stock is listed
on a securities exchange, the last reported sales price of the Common Stock on
such exchange which shall be for consolidated trading if applicable to such
exchange, or if neither so reported or listed, the last reported bid price of
the Common Stock. In the absence of such quotations, the Board of Directors of
the Company shall determine the current market price (i) based on the most
recently completed arm's-length transaction between the Company and a person
other than an Affiliate of the Company and the closing of which occurs on such
date or


                                       12
<PAGE>

shall have occurred within the three months preceding such date or (ii) if no
such transaction shall have occurred on such date or within such three-month
period, the value of the security determined in good faith by (A) the Board of
Directors of the Company, which determination shall be described in a Board
resolution or (B) by an independent nationally recognized investment banking
firm or appraisal firm.

               (g)    CONSIDERATION RECEIVED.

               For purposes of any computation respecting consideration received
pursuant to subsections (d) and (e) of this Section 10, the following shall
apply:

               (1) in the case of the issuance of shares of Common Stock for
        cash, the consideration shall be the amount of such cash, provided that
        in no case shall any deduction be made for any commissions, discounts or
        other expenses incurred by the Company for any underwriting of the issue
        or otherwise in connection therewith;

               (2) in the case of the issuance of shares of Common Stock for a
        consideration in whole or in part other than cash, the consideration
        other than cash shall be deemed to be the fair market value thereof as
        determined in good faith by the Board of Directors (irrespective of the
        accounting treatment thereof), whose determination shall be conclusive,
        absent manifest error, and described in a Board resolution;

               (3) in the case of the issuance of securities convertible into or
        exchangeable for shares, the aggregate consideration received therefor
        shall be deemed to be the consideration received by the Company for the
        issuance of such securities plus the additional minimum consideration,
        if any, to be received by the Company upon the conversion or exchange
        thereof (the consideration in each case to be determined in the same
        manner as provided in clauses (1) and (2) of this subsection).

               (h)    WHEN DE MINIMIS ADJUSTMENT MAY BE DEFERRED.

               No adjustment in the number of Warrant Shares issuable upon
exercise of one Warrant need be made unless the adjustment would require an
increase or decrease of at least 1% in the number of Warrant Shares issuable
upon exercise of one Warrant. Any adjustments that are not made shall be carried
forward and taken into account in any subsequent adjustment.

               All calculations under this Section shall be made to the nearest
1/100th of a share.

               (i)    WHEN NO ADJUSTMENT REQUIRED.

               No adjustment need be made for a transaction referred to in
Section 10(a), (b), (c), (d) or (e), if Holders are to participate (without
being required to exercise their Warrants) in the transaction on a basis and
with notice that the Board of Directors of the Company determines


                                       13
<PAGE>

to be fair and appropriate in light of the basis and notice on which Holders of
Common Stock participate in the transaction.

               No adjustment need be made for rights to purchase Common Stock
pursuant to a Company plan for reinvestment of dividends or interest.

               No adjustment need be made for a change in the par value or no
par value of the Common Stock.

               To the extent the Warrants become convertible into cash, no
adjustment need be made thereafter as to the cash. Interest will not accrue on
the cash.

               (j) NOTICE OF ADJUSTMENT.

               Whenever the number of Warrant Shares issuable upon exercise of
one Warrant is adjusted, the Company shall provide the notices required by
Section 12 hereof.

               (k) REORGANIZATION OF COMPANY.

               If the Company consolidates or merges with or into, or transfers
or leases all or substantially all its assets to, any person, upon consummation
of such transaction the Warrants shall automatically become exercisable for the
kind and amount of securities, cash or other assets which the Holder of a
Warrant would have owned immediately after the consolidation, merger, transfer
or lease if the Holder had exercised the Warrant immediately before the
effective date of the transaction. Concurrently with the consummation of such
transaction, the corporation formed by or surviving any such consolidation or
merger if other than the Company, or the person to which such sale or conveyance
shall have been made, shall enter into a supplemental Warrant Agreement so
providing and further providing for adjustments which shall be as nearly
equivalent as may be practical to the adjustments provided for in this Section.
The successor company shall mail to Holders a notice describing the supplemental
Warrant Agreement as soon as reasonably practicable after the execution of any
such supplemental Warrant Agreement.

               If the issuer of securities deliverable upon exercise of Warrants
under the supplemental Warrant Agreement is an affiliate of the formed,
surviving, transferee or lessee corporation, that issuer shall join in the
supplemental Warrant Agreement.

               If this subsection (k) applies, subsections (a), (b), (c), (d)
and (e) of this Section 10 do not apply.

               (l)    COMPANY DETERMINATION FINAL.

                                       14
<PAGE>

               Any determination that the Company or the Board of Directors must
make pursuant to subsection (a), (b), (c), (d), (e), (f), (g), (h) or (i) of
this Section 10 which is made in good faith shall be conclusive absent manifest
error.

               (m)    WHEN ISSUANCE OR PAYMENT MAY BE DEFERRED.

               In any case in which this Section 10 shall require that an
adjustment in the number of Warrant Shares issuable upon exercise of one Warrant
be made effective as of a record date for a specified event, the Company may
elect to defer until the occurrence of such event (i) issuing to the Holder of
any Warrant exercised after such record date the Warrant Shares and other
capital stock of the Company, if any, issuable upon such exercise over and above
the Warrant Shares and other capital stock of the Company, if any, issuable upon
such exercise on the basis of the current number of Warrant Shares issuable upon
exercise of one Warrant and (ii) paying to such Holder any amount in cash in
lieu of a fractional share pursuant to Section 11; PROVIDED, HOWEVER, that the
Company shall deliver to such Holder a due bill or other appropriate instrument
evidencing such Holder's right to receive such additional Warrant Shares, other
capital stock and cash upon the occurrence of the event requiring such
adjustment.

               (n)    ADJUSTMENT IN EXERCISE PRICE.

               Upon each adjustment of the number of Warrant Shares pursuant to
this Section 10, the Exercise Price for each Warrant outstanding prior to the
making of the adjustment in the number of Warrant Shares shall thereafter be
adjusted to the Exercise Price (calculated to the nearest hundredth of one cent)
obtained from the following formula:

                      E'= E x N
                              -
                              N'

where:

           E' = the adjusted Exercise Price.

           E = the Exercise Price prior to adjustment.

           N' = the adjusted number of Warrant Shares issuable upon exercise of
                a Warrant.

           N  = the number or Warrant Shares previously issuable upon exercise
                of a Warrant prior to adjustment.

               (o) FORM OF WARRANTS.

               Irrespective of any adjustments in the number or kind of shares
purchasable upon the exercise of the Warrants, Warrants theretofore or
thereafter issued may continue to express


                                       15
<PAGE>

the same price and number and kind of shares as are stated in the Warrants
initially issuable pursuant to this Agreement.

               SECTION 11. FRACTIONAL INTERESTS. Any one Warrant may be
exercised only in full and not in part. The Company shall not be required to
issue fractional Warrant Shares on the exercise of Warrants. If more than one
Warrant shall be presented for exercise at the same time by the same Holder, the
number of full Warrant Shares which shall be issuable upon the exercise thereof
shall be computed on the basis of the aggregate number of Warrant Shares
purchasable on exercise of the Warrants so requested to be exercised. If any
fraction of a Warrant Share would, except for the provisions of this Section 11,
be issuable on the exercise of any Warrants (or specified portion thereof), the
Company shall pay an amount in cash equal to the product of (i) such fraction of
a Warrant Share and (ii) the difference between the current market price of a
share of Common Stock and the Exercise Price.

               SECTION 12. NOTICES TO WARRANT HOLDERS. Upon any adjustment of
the Exercise Price or the number of Warrant Shares issuable upon exercise of one
Warrant pursuant to Section 10, the Company shall promptly thereafter (i) cause
to be filed with the Company a certificate which includes the report of a firm
of independent public accountants of recognized standing selected by the Board
of Directors of the Company (who may be the regular auditors of the Company)
setting forth the Exercise Price and the number of Warrant Shares issuable upon
exercise of one Warrant after such adjustment and setting forth in reasonable
detail the method of calculation and the facts upon which such calculations are
based, which certificate shall be conclusive evidence of the correctness of the
matters set forth therein absent manifest error, and (ii) cause to be given to
each of the registered Holders of the Warrant Certificates at his or her address
appearing on the Warrant register written notice of such adjustments by
first-class mail, postage prepaid. Where appropriate, such notice may be given
in advance and included as a part of the notice required to be mailed under the
other provisions of this Section 12.

               In case:

               (a) of any consolidation or merger to which the Company is a
        party and for which approval of any shareholders of the Company is
        required, or of the conveyance or transfer of the properties and assets
        of the Company substantially as an entirety, or of any reclassification
        or change of Common Stock issuable upon exercise of the Warrants (other
        than a change in par value, or from par value to no par value, or from
        no par value to par value, or as a result of a subdivision or
        combination), or a tender offer or exchange offer for shares of Common
        Stock; or

               (b) of the voluntary or involuntary dissolution, liquidation or
        winding up of the Company; or

                                       16
<PAGE>

               (c) the Company proposes to take any action which would require
        an adjustment of the number of Warrant Shares issuable upon exercise of
        one Warrant pursuant to Section 10;

then the Company shall cause to be given to each of the registered Holders of
the Warrant Certificates at his or her address appearing on the Warrant
register, at least 20 days (or 10 days in any case specified in clauses (a) or
(b) above) prior to the applicable record date hereafter specified, or promptly
in the case of events for which there is no record date, by first class mail,
postage prepaid, a written notice stating (i) the date as of which the holders
of record of shares of Common Stock to be entitled to receive any such rights,
options, warrants or distribution are to be determined, or (ii) the initial
expiration date set forth in any tender offer or exchange offer for shares of
Common Stock, or (iii) the date on which any such consolidation, merger,
conveyance, transfer, dissolution, liquidation or winding up is expected to
become effective or consummated, and the date as of which it is expected that
holders of record of shares of Common Stock shall be entitled to exchange such
shares for securities or other property, if any, deliverable upon such
reclassification, consolidation, merger, conveyance, transfer, dissolution,
liquidation or winding up. The failure to give the notice required by this
Section 12 or any defect therein shall not affect the legality or validity of
any distribution, right, option, warrant, consolidation, merger, conveyance,
transfer, dissolution, liquidation or winding up, or the vote upon any action.

               Nothing contained in this Agreement or in any of the Warrant
Certificates shall be construed as conferring upon the Holders thereof the right
to vote or to consent or to receive notice as shareholders in respect of the
meetings of shareholders or the election of Directors of the Company or any
other matter, or any rights whatsoever as shareholders of the Company.

               SECTION 13.   REGISTRATION RIGHTS.

               (a)    PIGGYBACK REGISTRATION.

               If the Company at any time proposes to register any Registrable
Securities under the Securities Act for sale to the public, whether for its own
account or for the account of other securityholders or both (except (x) in
connection with an initial public offering of Common Stock or (x) with respect
to registration statements on Form S-4 or S-8 or another form not available for
registering the Registrable Securities for sale to the public), it will give
written notice at such time to all Holders of outstanding Registrable Securities
of its intention to do so. Upon the written request of any such Holder, given
within 20 days after receipt of any such notice by the Company, to register any
of its Registrable Securities (which request shall state the intended method of
disposition thereof), the Company will use its best efforts to cause the
Registrable Securities, as to which registration shall have been so requested,
to be included in the securities to be covered by the registration statement
proposed to be filed by the Company, all to the extent required to permit the
sale or other disposition by the Holder (in accordance with its written request)
of such Registrable Securities so registered; PROVIDED that nothing herein shall
prevent the Company from abandoning or delaying such registration at any time;
PROVIDED FURTHER

                                       17
<PAGE>

that the only securities the Company shall be required to register pursuant
hereto with respect to a registration statement shall be Registrable Securities
of the same class of securities as proposed by the Company to be registered on
such registration statement (except that the Company shall be required to
register Warrants with respect to a registration statement in connection with
the registration of Common Stock). In the event that any registration pursuant
to this Section 13(a) shall be, in whole or in part, an underwritten public
offering of Registrable Securities, any request by a Holder pursuant to this
Section 13(a) to register Registrable Securities shall specify that either (i)
such Registrable Securities are to be included in the underwriting on the same
terms and conditions as the shares of Registrable Securities otherwise being
sold through underwriters under such registration or (ii) such Registrable
Securities are to be sold in the open market without any underwriting, on terms
and conditions comparable to those normally applicable to offerings of such
securities in reasonably similar circumstances. The number of shares of
Registrable Securities to be included in such an underwriting may be reduced
(PRO RATA among the Holders of Registrable Securities requesting registration
pursuant to this Section 13(a) based on the number of shares of Registrable
Securities owned by any such Holder on the date of such request out of the total
outstanding shares of Registrable Securities on that date) if and to the extent
that the managing underwriter shall be of the opinion that such inclusion would
adversely affect the marketing of the securities to be sold by the Company
therein; PROVIDED, HOWEVER, that such number of shares of Registrable Securities
shall not be reduced if any shares are to be included in such underwriting for
the account of any person other than the Company and the Holders of Registrable
Securities.

               Notwithstanding anything to the contrary contained in this
Section 13(a) hereof, in the event that there is a firm commitment underwritten
public offering of securities of the Company pursuant to a registration covering
Registrable Securities and a Holder of Registrable Securities does not elect to
sell his Registrable Securities to the underwriters of the Company's securities
in connection with such offering, such Holder shall, to the extent required by
such underwriters with respect to all Holders of Registrable Securities, refrain
from selling such Registrable Securities during the period of distribution of
the Company's securities by such underwriters and the period in which the
underwriting syndicate participates in the after market; PROVIDED, HOWEVER, that
such Holder shall, in any event, be entitled to sell its Registrable Securities
commencing on the 120th day after the effective date of such registration
statement.

               (b)    REGISTRATION PROCEDURES.

               If and whenever the Company is required by the provisions of
Section 13(a) hereof to use its best efforts to effect the registration of any
of the Registrable Securities held by Holders under the Securities Act, the
Company will, as expeditiously as possible:

               (i) in accordance with the Securities Act and all applicable
        rules and regulations, prepare (and afford counsel for the selling
        holders reasonable opportunity to review and comment thereon) and file
        with the Commission a registration statement with respect to such
        securities and use its best efforts to cause such registration statement
        to


                                       18
<PAGE>

        become and remain effective for the period of the distribution
        contemplated thereby (determined as hereinafter provided);

               (ii) prepare (and afford counsel for the selling holders
        reasonable opportunity to review and comment thereon) and file with the
        Commission such amendments and supplements to such registration
        statement and the prospectus used in connection therewith and any
        documents incorporated by reference therein and file such other
        documents as may be necessary to keep such registration statement
        effective for the period specified in paragraph (a) above and to comply
        with the provisions of the Securities Act with respect to the
        disposition of all Registrable Securities covered by such registration
        statement in accordance with the sellers' intended method of disposition
        set forth in such registration statement for such period;

               (iii) furnish to each seller and to each underwriter such number
        of copies of the registration statement and the prospectus included
        therein (including each preliminary prospectus), and all amendments,
        supplements, and exhibits thereto, and such other documents as such
        persons may reasonably request in order to facilitate the public sale or
        other disposition of the Registrable Securities covered by such
        registration statement (and the Company hereby consents to the use of
        any such prospectus, together with such supplements and amendments, by
        the sellers and underwriters, if any, in connection with the offer and
        sale covered thereby);

               (iv) use its best efforts to register or qualify the Registrable
        Securities covered by such registration statement under the securities
        or blue sky laws of such jurisdictions as the sellers of Registrable
        Securities or, in the case of an underwritten public offering, the
        managing underwriter, shall reasonably request (provided that the
        Company will not be required to (A) qualify generally to do business in
        any jurisdiction where it would not otherwise be required to qualify but
        for this paragraph (iv), (B) subject itself to taxation in any such
        jurisdiction or (C) consent to general service of process in any
        jurisdiction);

               (v) immediately notify each seller under such registration
        statement and each underwriter, (A) when such registration statement or
        any post-effective amendment or supplement thereto becomes effective or
        a supplement to any prospectus forming a part of such registration
        statement has been filed; (B) of the issuance by the Commission or any
        state securities authority of any stop order, injunction or other order
        or requirement suspending the effectiveness of such registration
        statement (and the Company shall use best efforts to prevent the
        initiation of proceedings for, prevent the entry of and/or remove such
        order or requirement); (C) of the happening of any event as a result of
        which such registration statement, as then in effect, the prospectus
        contained therein or any document incorporated by reference therein
        includes an untrue statement of a material fact or omits to state any
        material fact required to be stated therein or necessary to make the
        statements therein not misleading in the light of the circumstances then
        existing; or (D) of any


                                       19
<PAGE>

        request by the Commission for the amending or supplementing of such
        registration statement or prospectus or for additional information;

               (vi) use its best efforts to furnish, at the request of any
        seller, on the date that Registrable Securities are delivered to the
        underwriters for sale pursuant to such registration statement, if such
        securities are being sold through underwriters, or on the date that the
        registration statement becomes effective, if such securities are not
        being sold through underwriters: (A) an opinion dated such date of
        counsel representing the Company for the purposes of such registration,
        addressed to the underwriters, if any, and to such seller, stating that
        such registration statement has become effective under the Securities
        Act and that (1) to the best knowledge of such counsel, no stop order
        suspending the effectiveness thereof has been issued and no proceedings
        for that purpose have been instituted or are pending or contemplated
        under the Securities Act, (2) the registration statement, the related
        prospectus, and each amendment or supplement thereof, comply as to form
        in all material respects with the requirements of the Securities Act and
        the applicable rules and regulations of the Commission thereunder
        (except that such counsel need express no opinion as to financial
        statements, the notes thereto, and the financial schedules and other
        financial and statistical data contained therein) and (3) to such other
        effects as may reasonably be requested by counsel for the underwriters
        or by such seller or its counsel, and (B) a letter dated such date from
        the independent public accountants retained by the Company, addressed to
        the underwriters, if any, and to such sellers stating that they are
        independent public accountants within the meaning of the Securities Act
        and that, in the opinion of such accountants, the financial statements
        of the Company included in the registration statement or the prospectus,
        or any amendment or supplement thereof, comply as to form in all
        material respects with the applicable accounting requirements of the
        Securities Act, and such letter shall additionally cover such other
        financial matters (including information as to the period ending no more
        than five business days prior to the date of such letter) with respect
        to the registration in respect of which such letter is being given as
        such underwriters or sellers may reasonably request;

               (vii) take such actions as may be necessary or appropriate to
        cause the Registrable Securities so to be registered to be listed on the
        principal securities exchange (or on the NASDAQ National Market System,
        as the case may be) on which shares of Registrable Securities are then
        traded (or, in the case of an initial public offering, on such national
        securities exchange (or on the NASDAQ National Market System) as the
        Company shall elect);

               (viii) use its best efforts to comply with all applicable rules
        and regulations of the Commission, and make available to any Holder of
        Registrable Securities, as soon as reasonably practicable (but not more
        than 15 months) after the effective date of the registration statement,
        an earnings statement which shall satisfy the provisions of Section
        11(a) of the Securities Act and the rules and regulations promulgated
        thereunder; and

                                       20
<PAGE>

               (ix) make available for inspection by each seller, any
        underwriter participating in any distribution pursuant to such
        registration statement, and any attorney, accountant or other agent
        retained by such seller or underwriter, all financial and other records,
        pertinent corporate documents and properties of the Company, and cause
        the Company's officers, directors and employees to supply all
        information reasonably requested by any such seller, underwriter,
        attorney, accountant or agent in connection with such registration
        statement and permit such seller, attorney, accountant or agent to
        participate in the preparation of such registration statement.

For purposes of paragraphs (i) and (ii) above hereof, the period of distribution
of Registrable Securities in a firm commitment underwritten public offering
shall be deemed to extend until each underwriter has completed the distribution
of all securities purchased by it, and the period of distribution of Registrable
Securities in any other registration shall be deemed to extend until the earlier
of the sale of all Registrable Securities covered thereby or six months after
the effective date thereof.

               In connection with each registration hereunder, the selling
Holders of Registrable Securities will furnish to the Company in writing such
information with respect to themselves and the proposed distribution by them as
shall be reasonably necessary in order to assure compliance with federal and
applicable state securities laws.

               In connection with each registration pursuant to Section 13(a)
hereof covering an underwritten public offering, the Company agrees to enter
into a written agreement with the managing underwriter selected in the manner
herein provided in such form and containing such provisions as are customary in
the securities business for such an arrangement between major underwriters and
companies of the Company's size and investment stature; PROVIDED, HOWEVER, that
such agreement shall not contain any such provision applicable to the Company
which is inconsistent with the provisions hereof and PROVIDED, FURTHER, HOWEVER,
that the time and place of the closing under said agreement shall be as mutually
agreed upon among the Company, such managing underwriter and the selling Holders
of Registrable Securities.

               (c)    EXPENSES.

               All expenses incurred by the Company in complying with Section
13(a) hereof, including, without limitation, all registration, listing and
filing fees, printing expenses, fees and disbursements of counsel and
independent public accountants for the Company (including with respect to any
special audit or "cold comfort" letters), fees of the National Association of
Securities Dealers, Inc., transfer taxes and fees of transfer agents and
registrars, as well as reasonable fees and out-of pocket expenses of not more
than one counsel for all the Holders, but excluding any Selling Expenses, are
herein called "REGISTRATION EXPENSES." All underwriting discounts and selling
commissions applicable to the sale of Registrable Securities are herein called
"SELLING EXPENSES."

                                       21
<PAGE>

               The Company will pay all Registration Expenses in connection with
each registration statement filed pursuant to Section 13(a) hereof. All Selling
Expenses in connection with any registration statement filed pursuant to Section
13(a) hereof shall be borne by the participating sellers in proportion to the
number of shares sold by each, or by such persons other than the Company (except
to the extent the Company shall be a seller) as they may agree.

               (d)    INDEMNIFICATION.

               In the event of a registration of any of the Registrable
Securities under the Securities Act pursuant to Section 13(a) hereof, the
Company will indemnify and hold harmless, to the fullest extent permitted by
law, each seller of such Registrable Securities thereunder, each underwriter of
Registrable Securities thereunder, each of their respective affiliates, each of
their and their affiliates' respective directors, officers, fiduciaries,
trustees, agents, employees, stockholders, general and limited partners and
members, and each other person, if any, who controls such seller or underwriter
within the meaning of the Securities Act, against any losses, claims, damages or
liabilities, joint or several, actions or proceedings (whether commenced or
threatened) in respect thereof (all of the foregoing, collectively, "CLAIMS")
and expenses (including fees and expenses of counsel, and amounts paid in any
settlement effected with the Company's consent, which consent shall not be
unreasonably withheld or delayed) to which such indemnified party may become
subject under the Securities Act or otherwise, insofar as such Claims or
expenses arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in any registration statement under
which such Registrable Securities were registered under the Securities Act
pursuant to Section 13(a), any preliminary prospectus, summary or final
prospectus contained therein, or any amendment or supplement of any thereof, or
any documents incorporated by reference therein, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and will reimburse each such indemnified party for any legal or other expenses
incurred by them in connection with investigating or defending any such Claim;
PROVIDED, HOWEVER, that the Company will not be liable to any such indemnified
party if and to the extent that any such Claim or expense arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission so made in conformity with information pertaining to such
indemnified party furnished by such indemnified party in writing specifically
for use in such registration statement or prospectus.

               In the event of a registration of any of the Registrable
Securities under the Securities Act pursuant to Section 13(a) hereof, each
seller of such Registrable Securities thereunder, severally and not jointly,
will indemnify and hold harmless, to the fullest extent permitted by law, the
Company and each person, if any, who controls the Company within the meaning of
the Securities Act, each officer of the Company who signs the registration
statement, each director of the Company, each underwriter and each person who
controls any underwriter within the meaning of the Securities Act, each other
Holder selling Registrable Securities under

                                       22
<PAGE>

such registration statement and each affiliate, officer, director, fiduciary,
trustee, agent, employee, stockholder, general or limited partner or member of
such selling Holder against all Claims and expenses (including fees and expenses
of counsel, and amounts paid in any settlement effected with the indemnifying
party's consent, which consent shall not be unreasonably withheld or delayed) to
which the Company or such officer or director or underwriter or controlling
person may become subject under the Securities Act or otherwise, insofar as such
Claims or expenses arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the registration
statement under which such Registrable Securities were registered under the
Securities Act pursuant to Section 13(a) any preliminary prospectus, summary or
final prospectus contained therein, or any amendment or supplement of any
thereof, or any documents incorporated by reference therein, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse the Company and each such indemnified party for
any legal or other expenses incurred by them in connection with investigating or
defending any such Claim; PROVIDED, HOWEVER, that such seller will be liable
hereunder to any such indemnified party if and only to the extent that any such
Claim or expense arises out of or is based upon an untrue statement or alleged
untrue statement or omission or alleged omission made in reliance upon and in
conformity with information pertaining to such seller, as such, furnished in
writing to the Company by such seller specifically for use in such registration
statement or prospectus; PROVIDED, FURTHER, HOWEVER, that the liability of each
seller hereunder shall be limited to the proceeds (net of underwriting discounts
and commissions) received by such seller from the sale of Registrable Securities
covered by such registration statement.

               Promptly after receipt by an indemnified party hereunder of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to such indemnified party under this Section 13(d) except to the extent such
indemnifying party is materially prejudiced thereby, and in any event will not
relieve such indemnifying party from any liability which it may have to any
indemnified party other than under this Section 13(d). In case any such action
shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate in and, to the extent it shall wish, to assume and
undertake the defense thereof with counsel satisfactory to such indemnified
party, and, after notice from the indemnifying party to such indemnified party
of its election so to assume and undertake the defense thereof, the indemnifying
party shall not be liable to such indemnified party under this Section 13(d) for
any legal expenses subsequently incurred by such indemnified party in connection
with the defense thereof other than reasonable costs of investigation and of
liaison with counsel so selected; PROVIDED, HOWEVER, that, if the defendants in
any such action include both the indemnified party and the indemnifying party
and the indemnified party shall have reasonably concluded that there may be
reasonable defenses available to it which are different from or additional to
those available to the indemnifying party, or if the interests of the

                                       23
<PAGE>

indemnified party reasonably may be deemed to conflict with the interests of the
indemnifying party, or if the indemnifying party shall not diligently continue
such defense in good faith, the indemnified party shall have the right to select
a separate counsel and to assume such legal defenses and otherwise to
participate in the defense of such action, with the expenses and fees of such
separate counsel and other expenses related to such participation to be
reimbursed by the indemnifying party as incurred.

               Notwithstanding the foregoing, any indemnified party shall have
the right to retain its own counsel in any such action, but except as set forth
above the fees and disbursements of such counsel shall be at the expense of such
indemnified party unless (i) the indemnifying party shall have failed to retain
counsel for the indemnified person as aforesaid or (ii) the indemnifying party
and such indemnified party shall have mutually agreed to the retention of such
counsel. It is understood that the indemnifying party shall not, in connection
with any action or related actions in the same jurisdiction, be liable for the
fees and disbursements of more than one firm (together with local counsel) to
act as counsel for the indemnified party. The indemnifying party shall not be
liable for any settlement of any proceeding effected without its written consent
(which shall not be unreasonably withheld or delayed), but if settled with such
consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party from and against any loss or
liability by reason of such settlement or judgment. No indemnifying party shall,
without the written consent of the indemnified party (which shall not be
unreasonably withheld or delayed), effect the settlement or compromise of, or
consent to the entry of any judgment with respect to, any pending or threatened
action in respect of which indemnification may be sought hereunder (whether or
not the indemnified party is an actual or potential party to such action) unless
such settlement, compromise or judgment (i) includes an unconditional release of
such indemnified party from all liability arising out of such action and (ii)
does not include a statement as to or an admission of fault, culpability or a
failure to act by or on behalf of such indemnified party.

               If for any reason the indemnification provided for in the first
two paragraphs of this Section 13(d) is unavailable or insufficient to hold
harmless an indemnified party under such paragraphs in respect of any Claims or
expenses in respect thereof referred to therein, then each indemnifying party
shall in lieu of indemnifying such indemnified party contribute to the amount
paid or payable by such indemnified party as a result of such Claims or expenses
in such proportion as appropriate to reflect the relative fault of the Company,
on the one hand, and the underwriters and the sellers of such Registrable
Securities, on the other, in connection with the statements or omissions which
resulted in such Claims or expenses as well as any other relevant equitable
considerations, including the failure to give any notice under the third
paragraph of this Section 13(d). The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact relates to information supplied by the indemnifying party, on
the one hand, or the indemnified party, on the other, and to the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company and each of you agree that it
would not be just and equitable if contributions pursuant to this paragraph were
determined by PRO RATA allocation (even


                                       24
<PAGE>

if all of the sellers of such Registrable Securities were treated as one entity
for such purpose) or by any other method of allocation which did not take
account of the equitable considerations referred to above in this paragraph. The
amount paid or payable by an indemnified party as a result of the Claims and
expenses in respect thereof, referred to above in this paragraph, shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this paragraph, no seller of such
Registrable Securities or related indemnified party shall be required to
contribute any amount in excess of the amount of proceeds (net of underwriting
discounts and commissions) received by such seller from the sale of Registrable
Securities covered by such registration statement. No person guilty of
fraudulent misrepresentations (within the meaning of Section 11(f) of the
Securities Act), shall be entitled to contribution from any person who is not
guilty of such fraudulent misrepresentation.

               The indemnification of underwriters provided for in this Section
13(d) shall be on such other terms and conditions as are at the time customary
and reasonably required by such underwriters. In that event the indemnification
of the sellers of Registrable Securities in such underwriting shall at the
sellers' request be modified to conform to such terms and conditions.

               The indemnification and contribution agreements contained herein
shall be in addition to any other rights to indemnification and contribution
which any indemnified party may have pursuant to law or contract or otherwise,
shall remain operative and in full force and effect regardless of any
investigation made or omitted by or on behalf of any indemnified party and shall
survive the transfer of Registrable Securities by any such party.

               (e)    CERTAIN DEFINITION.

               The term "Registrable Securities" shall mean the Warrants, the
        Warrant Shares and the Additional Warrant Shares, if any. As to any
        particular Registrable Securities, once issued such securities shall
        cease to be Registrable Securities when (A) a registration statement
        with respect to the sale of such securities shall have become effective
        under the Securities Act and such securities shall have been disposed of
        in accordance with such registration statement, (B) they shall have been
        distributed to the public pursuant to Rule 144 (or any successor
        provision) under the Securities Act, (C) they shall have been otherwise
        transferred, new certificates for them not bearing a legend restricting
        further transfer shall have been delivered by the Company and subsequent
        disposition of them shall not require registration or qualification of
        them under the Securities Act or any similar state law then in force, or
        (D) they shall have ceased to be outstanding.

               SECTION 14. NOTICES TO COMPANY AND WARRANT HOLDER. Any notice or
demand authorized by this Agreement to be given or made by the registered Holder
of any Warrant Certificate to or on the Company shall be sufficiently given or
made when and if deposited in the mail, first class or registered, postage
prepaid, addressed to the office of the Company expressly

                                       25
<PAGE>

designated by the Company at its office for purposes of this Agreement (until
the Holders are otherwise notified in accordance with this Section by the
Company), as follows:

                      Concentra Managed Care, Inc.
                      312 Union Wharf
                      Boston, MA 02109

                      Attention: General Counsel

               Any notice pursuant to this Agreement to be given by the Company
to the registered Holder(s) of any Warrant Certificate shall be sufficiently
given when and if deposited in the mail, first class or registered, postage
prepaid, addressed (until the Company is otherwise notified in accordance with
this Section by such Holder) to such Holder at the address appearing on the
Warrant register of the Company.

               SECTION 15. SUPPLEMENTS AND AMENDMENTS. The Company may from time
to time supplement or amend this Agreement without the approval of any Holders
of Warrant Certificates in order to cure any ambiguity or to correct or
supplement any provision contained herein which may be defective or inconsistent
with any other provision herein, or to make any other provisions in regard to
matters or questions arising hereunder which the Company may deem necessary or
desirable and which shall not in any way adversely affect the interests of the
Holders of Warrant Certificates or discriminate against any Holder of Warrant
Certificates. Any amendment or supplement to this Agreement that has an adverse
effect on the interests of Holders shall require the written consent of
registered Holders of two-thirds of the then outstanding Warrant Shares issued
or issuable upon exercise of the Warrants (excluding Warrant Shares held by the
Company or any of its Affiliates). The consent of each Holder of a Warrant
affected shall be required for any amendment pursuant to which the number of
Warrant Shares purchasable upon exercise of Warrants would be decreased or the
Exercise Price increased (other than in accordance with Section 10 or 11
hereof).

               SECTION 16.  SUCCESSORS.  All the covenants and provisions of
this Agreement by or for the benefit of the Company shall bind and inure to the
benefit of its respective successors and assigns hereunder.

               SECTION 17.  TERMINATION.  This Agreement (except for Section
13(d) and for the restrictions on transfer of Warrant Shares specified in
Section 4) shall terminate at 5:00 p.m., New York City time on August 15, 2010.

               SECTION 18. GOVERNING LAW. THIS AGREEMENT AND EACH WARRANT
CERTIFICATE ISSUED HEREUNDER SHALL BE DEEMED TO BE A CONTRACT MADE UNDER THE
LAWS OF THE STATE OF NEW YORK AND FOR ALL PURPOSES SHALL BE CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF SAID STATE.

                                       26
<PAGE>

               SECTION 19. BENEFITS OF THIS AGREEMENT. Nothing in this Agreement
shall be construed to give to any person or corporation other than the Company
and the registered Holders of the Warrant Certificates or Warrant Shares any
legal or equitable right, remedy or claim under this Agreement; but this
Agreement shall be for the sole and exclusive benefit of the Company and the
registered Holders of the Warrant Certificates and the Warrant Shares. Nothing
herein shall prohibit or limit the Company from entering into an agreement
providing holders of securities which may hereafter be issued by the Company
with such registration rights exercisable at such time or times and in such
manner as the Board of Directors shall deem in the best interests of the Company
so long as the performance by the Company of its obligations under such other
agreement will not cause the Company to breach its obligations hereunder to the
Holders.

               SECTION 20. COUNTERPARTS. This Agreement may be executed in any
number of counterparts and each of such counterparts shall for all purposes be
deemed to be an original, and all such counterparts shall together constitute
but one and the same instrument.

money of the United States of America upon surrender of this Warrant Certificate
and payment of the Exercise Price at the office of the Company designated for
such purpose, but only subject to the conditions set forth herein and in the
Warrant Agreement referred to on the reverse hereof. In lieu of exercising this
Warrant by paying in full the Exercise Price plus transfer taxes (if applicable
pursuant to Section 6 of the Warrant Agreement), if any, the Warrant holder may,
from time to time, convert this Warrant, in whole or in part, into a number of
Warrant Shares determined by dividing (a) the aggregate current market price of
the number of shares of Common Stock represented by the Warrants converted,
minus the aggregate Exercise Price for such shares of Common Stock, minus
transfer taxes, if any, by (b) the current market price of one share of Common
Stock. The current market price shall be determined pursuant to Section 10(f) of
the Warrant Agreement.

               The number of Warrant Shares and Additional Warrant Shares, if
any, issuable upon exercise of the Warrants is subject to adjustment upon the
occurrence of certain events set forth in the Warrant Agreement.

Warrant Certificate set forth on the reverse hereof and such further provisions
shall for all purposes have the same effect as though fully set forth at this

               The Warrants evidenced by this Warrant Certificate are part of a
duly authorized issue of Warrants expiring August 15, 2010, entitling the holder
on exercise to receive shares of Common Stock, $.01 par value, of the Company
(the "Common Stock"), and are issued or to be issued pursuant to a Warrant
Agreement dated as of August 17, 1999 (the "Warrant Agreement"), duly executed
and delivered by the Company, which Warrant Agreement is hereby incorporated by
reference in and made a part of this instrument and is hereby referred to for a
description of the rights, limitation of rights, obligations, duties and
immunities thereunder of the Company and the holders (the words "holders" or
"holder" meaning the registered holders or registered holder) of the Warrants. A
copy of the Warrant Agreement may be obtained by the holder hereof upon written
request to the Company.

               Subject to the terms of the Warrant Agreement, Warrants may be
exercised commencing at the opening of business on the Exercisability Date and
until 5:00 p.m., New York City time, on August 15, 2010. The holder of Warrants
evidenced by this Warrant Certificate may exercise them by surrendering this
Warrant Certificate, with the form of election to purchase set forth hereon
properly completed and executed, together with payment of the Exercise Price in
cash at the office of the Company designated for such purpose. In lieu of
exercising this Warrant by paying in full the Exercise Price plus transfer taxes
(if applicable pursuant to Section 6 of the Warrant Agreement), if any, the
Warrant holder may, from time to time, convert this Warrant, in whole or in
part, into a number of shares of Common Stock determined by dividing (a) the
aggregate current market price of the number of Warrant Shares represented by
the Warrants converted, minus the aggregate Exercise Price for such shares of
Common Stock, minus transfer taxes, if any, by (b) the current market price of
one share of Common Stock. The current market price shall be determined pursuant
to Section 10(f) of the Warrant Agreement. In the event that upon any exercise
of Warrants evidenced hereby the number of Warrants exercised shall be less than
the total number of Warrants evidenced hereby, there shall be issued to the
holder hereof or his assignee a new Warrant Certificate evidencing the number of
Warrants not exercised.

               The Warrant Agreement provides that upon the occurrence of
certain events the number of Warrant Shares issuable upon exercise of one
Warrant set forth on the face hereof and the Exercise Price of a Warrant may,
subject to certain conditions, be adjusted. No fractions of a share of Common
Stock will be issued upon the exercise of any Warrant, but the Company will pay
the cash value thereof determined as provided in the Warrant Agreement.

               The holders of the Warrants are entitled to certain registration
rights with respect to the Common Stock purchasable upon exercise thereof. Said
registration rights are set forth in Section 13 of the Warrant Agreement.

               Warrant Certificates, when surrendered at the office of the
Company by the registered holder thereof in person or by legal representative or
attorney duly authorized in writing, may be exchanged, in the manner and subject
to the limitations provided in the Warrant Agreement, but without payment of any
service charge, for another Warrant Certificate or Warrant Certificates of like
tenor evidencing in the aggregate a like number of Warrants.

               Upon due presentation for registration of transfer of this
Warrant Certificate at the office of the Company a new Warrant Certificate or
Warrant Certificates of like tenor and evidencing in the aggregate a like number
of Warrants shall be issued to the transferee(s) in exchange for this Warrant
Certificate, subject to the limitations provided in the Warrant Agreement,
without charge except for any tax or other governmental charge imposed in
connection therewith.

               The Company may deem and treat the registered holder(s) thereof
as the absolute owner(s) of this Warrant Certificate (notwithstanding any
notation of ownership or other writing hereon made by anyone), for the purpose
of any exercise hereof, of any distribution to the holder(s) hereof, and for all
other purposes, and the Company shall not be affected by any notice to the
contrary. Neither the Warrants nor this Warrant Certificate entities any holder
hereof to any rights of a stockholder of the Company.

SECTION 2.     HOLDERS

         A Person is deemed to be a holder of Transfer Restricted Securities

SECTION 3.     REGISTERED EXCHANGE OFFER

         (a) Unless the Exchange Offer shall not be permitted by applicable
federal law (after the procedures set forth in Section 6(a)(i) below have been
complied with), the Company and the Guarantors shall (i) cause the Exchange
Offer Registration Statement to be filed with the Commission as soon as
practicable after the Closing Date, but in no event later than 90 days after the
Closing Date (such 90th day being the "FILING DEADLINE"), (ii) use its best
efforts to cause such Exchange Offer Registration Statement to become effective
at the earliest possible time, but in no event later than 180 days after the
Closing Date (such 180th day being the "EFFECTIVENESS DEADLINE"), (iii) in
connection with the foregoing, (A) file all pre-effective amendments to such
Exchange Offer Registration Statement as may be necessary in order to cause it
to become effective, (B) file, if applicable, a post-effective amendment to such
Exchange Offer Registration Statement pursuant to Rule 430A under the Act and
(C) cause all necessary filings, if any, in connection with the registration and
qualification of the Series B Notes to be made under the Blue Sky laws of such
jurisdictions as are necessary to permit Consummation of the Exchange Offer, and
(iv) upon the effectiveness of such Exchange Offer Registration Statement,
commence and Consummate the Exchange Offer. The Exchange Offer shall be on the
appropriate form permitting (i) registration of the Series B Notes to be offered
in exchange for the Series A Notes that are Transfer Restricted Securities and
(ii) resales of Series B Notes by Broker-Dealers that tendered into the Exchange
Offer Series A Notes that such Broker-Dealer acquired for its own account as a
result of market making activities or other trading activities (other than
Series A Notes acquired directly from the Company or any of its Affiliates) as
contemplated by Section 3(c) below.

         (b) The Company and the Guarantors shall use their respective best
efforts to cause the Exchange Offer Registration Statement to be effective
continuously, and shall keep the Exchange Offer open for a period of not less
than the minimum period required under applicable federal and state securities
laws to Consummate the Exchange Offer; PROVIDED, HOWEVER, that in no event shall
such period be less than 20 Business Days. The Company and the Guarantors shall
cause the Exchange Offer to comply in all material respects with all applicable
federal and state securities laws. No securities other than the Series B Notes
shall be included in the Exchange Offer Registration Statement. The Company and
the Guarantors shall use their respective best efforts to cause the Exchange
Offer to be Consummated on the earliest practicable date after the Exchange
Offer Registration Statement has become effective, but in no event later than 30
business days thereafter (such 30th day being the "CONSUMMATION DEADLINE").

         (c) The Company shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Transfer Restricted Securities that
were acquired for the account of such Broker-Dealer as a result of market-making

                                       4

<PAGE>

activities or other trading activities (other than Series A Notes acquired
directly from the Company or any Affiliate of the Company), may exchange such
Transfer Restricted Securities pursuant to the Exchange Offer. Such "Plan of
Distribution" section shall also contain all other information with respect to
such sales by such Broker-Dealers that the Commission may require in order to
permit such sales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Transfer Restricted
Securities held by any such Broker-Dealer, except to the extent required by the
Commission as a result of a change in policy, rules or regulations after the
date of this Agreement. See the SHEARMAN & STERLING no-action letter (available
July 2, 1993).

         Because such Broker-Dealer may be deemed to be an "underwriter" within
the meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with its initial sale of any Series B
Notes received by such Broker-Dealer in the Exchange Offer, the Company and the
Guarantors shall permit the use of the Prospectus contained in the Exchange
Offer Registration Statement by such Broker-Dealer to satisfy such prospectus
delivery requirement. To the extent necessary to ensure that the prospectus
contained in the Exchange Offer Registration Statement is available for sales of
Series B Notes by Broker-Dealers, the Company and the Guarantors agree to use
their respective best efforts to keep the Exchange Offer Registration Statement
continuously effective, supplemented, amended and current as required by and
subject to the provisions of Sections 6(a) and (c) hereof and in conformity with
the requirements of this Agreement, the Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period of
one year from the Consummation Deadline or such shorter period as will terminate
when all Transfer Restricted Securities covered by such Registration Statement
have been sold pursuant thereto. The Company and the Guarantors shall provide
sufficient copies of the latest version of such Prospectus to any such
Broker-Dealers from whom the Company has received prior written notice that it
will be such a Broker-Dealer in the Exchange Offer ("PARTICIPATING
BROKER-DEALER"), promptly upon request, and in no event later than one day after
such request, at any time during such period.

SECTION 4.     SHELF REGISTRATION

      (a) SHELF REGISTRATION. If (i) the Exchange Offer is not permitted by
applicable law (after the Company and the Guarantors have complied with the
procedures set forth in Section 6(a)(i) below) or (ii) if any Holder of Transfer
Restricted Securities shall notify the Company within 20 Business Days following
the Consummation Deadline that (A) such Holder was prohibited by law or
Commission policy from participating in the Exchange Offer or (B) such Holder
may not resell the Series B Notes acquired by it in the Exchange Offer to the
public without delivering a prospectus and the Prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales by such Holder or (C) such Holder is a Broker-Dealer and holds Series A
Notes acquired directly from the Company or any of its Affiliates, then the
Company and the Guarantors shall:

      (x) cause to be filed, on or prior to 60 days after the earlier of (i)
the date on which the Company determines that the Exchange Offer Registration
Statement cannot be filed as a result of clause (a)(i) above and (ii) the date
on which the Company receives the notice specified in clause (a)(ii) above,
(such earlier date, the "FILING DEADLINE"), a shelf registration statement
pursuant to Rule 415 under the Act (which may be an amendment to the Exchange
Offer Registration Statement (the "SHELF REGISTRATION STATEMENT")), relating to
all Transfer Restricted Securities, and

      (y) shall use their respective best efforts to cause such Shelf
Registration Statement to become effective on or prior to 180 days after the
Filing Deadline for the Shelf Registration Statement (such 180th day the
"EFFECTIVENESS DEADLINE").

                                       5

<PAGE>

         If, after the Company has filed an Exchange Offer Registration
Statement that satisfies the requirements of Section 3(a) above, the Company is
required to file and make effective a Shelf Registration Statement solely
because the Exchange Offer is not permitted under applicable federal law (i.e.,
clause (a)(i) above), then the filing of the Exchange Offer Registration
Statement shall be deemed to satisfy the requirements of clause (x) above;
PROVIDED that, in such event, the Company shall remain obligated to meet the
Effectiveness Deadline set forth in clause (y).

         To the extent necessary to ensure that the Shelf Registration Statement
is available for sales of Transfer Restricted Securities by the Holders thereof
entitled to the benefit of this Section 4(a) and the other securities required
to be registered therein pursuant to Section 6(b)(ii) hereof, the Company and
the Guarantors shall use their respective best efforts to keep any Shelf
Registration Statement required by this Section 4(a) continuously effective,
supplemented, amended and current as required by and subject to the provisions
of Sections 6(b) and (c) hereof and in conformity with the requirements of this
Agreement, the Act and the policies, rules and regulations of the Commission as
announced from time to time, for a period of at least two years (as extended
pursuant to Section 6(d)) following the Closing Date, or such shorter period as
will terminate when all Transfer Restricted Securities covered by such Shelf
Registration Statement have been sold pursuant thereto.

         (b) PROVISION BY HOLDERS OF CERTAIN INFORMATION IN CONNECTION WITH THE
SHELF REGISTRATION STATEMENT. No Holder of Transfer Restricted Securities may
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein. No Holder of Transfer
Restricted Securities shall be entitled to liquidated damages pursuant to
Section 5 hereof unless and until such Holder shall have provided all such
information. Each selling Holder agrees to promptly furnish additional
information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading.

SECTION 5.      LIQUIDATED DAMAGES

         If (i) any Registration Statement required by this Agreement is not
filed with the Commission on or prior to the applicable Filing Deadline, (ii)
any such Registration Statement has not been declared effective by the
Commission on or prior to the applicable Effectiveness Deadline, (iii) the
Exchange Offer has not been Consummated on or prior to the Consummation Deadline
or (iv) any Registration Statement required by this Agreement is filed and
declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose without being succeeded within 2 days by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself declared effective within 5 days of filing such
post-effective amendment to such Registration Statement (each such event
referred to in clauses (i) through (iv), a "REGISTRATION DEFAULT"), then the
Company and the Guarantors hereby jointly and severally agree to pay to each
Holder of Transfer Restricted Securities affected thereby liquidated damages in
an amount equal to $0.05 per week per $1,000 in principal amount of Transfer
Restricted Securities held by such Holder for each week or portion thereof that
the Registration Default continues for the first 90-day period immediately
following the occurrence of such Registration Default. The amount of the
liquidated damages shall increase by an additional $0.05 per week per $1,000 in
principal amount of Transfer Restricted Securities with respect to each
subsequent 90-day period until all Registration Defaults have been cured, up to
a maximum amount of liquidated damages of $0.50 per week per $1,000 in principal
amount of Transfer Restricted Securities; PROVIDED that the Company and the
Guarantors shall in no event be required to pay liquidated damages for more than
one Registration Default at any given time. Notwithstanding anything to the
contrary set forth herein, (1) upon filing of the Exchange Offer Registration
Statement (and/or, if applicable, the Shelf Registration Statement), in the case
of (i) above, (2) upon the effectiveness of the Exchange Offer Registration
Statement (and/or, if applicable, the Shelf Registration Statement), in the case
of (ii) above, (3) upon Consummation of the Exchange Offer, in the case of (iii)
above, or (4) upon the filing of a post-effective amendment to the Registration
Statement or an additional Registration Statement that causes the Exchange Offer
Registration Statement

                                       6

<PAGE>

(and/or, if applicable, the Shelf Registration Statement) to again be declared
effective or made usable in the case of (iv) above, the liquidated damages
payable with respect to the Transfer Restricted Securities as a result of such
clause (i), (ii), (iii) or (iv), as applicable, shall cease.

         All accrued liquidated damages shall be paid to the Holders entitled
thereto, in the manner provided for the payment of interest in the Indenture, on
each Interest Payment Date, as more fully set forth in the Indenture and the
Notes. Notwithstanding the fact that any securities for which liquidated damages
are due cease to be Transfer Restricted Securities, all obligations of the
Company and the Guarantors to pay liquidated damages with respect to securities
shall survive until such time as such obligations with respect to such
securities shall have been satisfied in full.

SECTION 6.      REGISTRATION PROCEDURES

         (a) EXCHANGE OFFER REGISTRATION STATEMENT. In connection with the
Exchange Offer, the Company and the Guarantors shall (x) comply with all
applicable provisions of Section 6(c) below, (y) use their respective best
efforts to effect such exchange and to permit the resale of Series B Notes by
Broker-Dealers that tendered in the Exchange Offer Series A Notes that such
Broker-Dealer acquired for its own account as a result of its market making
activities or other trading activities (other than Series A Notes acquired
directly from the Company or any of its Affiliates) being sold in accordance
with the intended method or methods of distribution thereof, and (z) comply with
all of the following provisions:

                (i) If, following the date hereof there has been announced a
      change in Commission policy with respect to exchange offers such as the
      Exchange Offer, that in the reasonable opinion of counsel to the Company
      raises a substantial question as to whether the Exchange Offer is
      permitted by applicable federal law, the Company and the Guarantors hereby
      agree to seek a no-action letter or other favorable decision from the
      Commission allowing the Company and the Guarantors to Consummate an
      Exchange Offer for such Transfer Restricted Securities. The Company and
      the Guarantors hereby agree to pursue the issuance of such a decision to
      the Commission staff level but shall not be required to take any
      commercially unreasonable action to effect a change of Commission policy.
      In connection with the foregoing, the Company and the Guarantors hereby
      agree to take all such other commercially reasonable actions as may be
      requested by the Commission or otherwise required in connection with the
      issuance of such decision, including without limitation (A) participate in
      telephonic conferences with the Commission, (B) deliver to the Commission
      staff an analysis prepared by counsel to the Company setting forth the
      legal bases, if any, upon which such counsel has concluded that such an
      Exchange Offer should be permitted and (C) diligently pursue a resolution
      (which need not be favorable) by the Commission staff.

                (ii) As a condition to its participation in the Exchange Offer,
      each Holder of Transfer Restricted Securities (including, without
      limitation, any Holder who is a Broker Dealer) shall furnish, upon the
      request of the Company, prior to the Consummation of the Exchange Offer, a
      written representation to the Company and the Guarantors (which may be
      contained in the letter of transmittal contemplated by the Exchange Offer
      Registration Statement) to the effect that (A) it is not an Affiliate of
      the Company, (B) it is not engaged in, and does not intend to engage in,
      and has no arrangement or understanding with any person to participate in,
      a distribution of the Series B Notes to be issued in the Exchange Offer
      and (C) it is acquiring the Series B Notes in its ordinary course of
      business. As a

                                       7

<PAGE>

      condition to its participation in the Exchange Offer each Holder using the
      Exchange Offer to participate in a distribution of the Series B Notes
      shall acknowledge and agree that, if the resales are of Series B Notes
      obtained by such Holder in exchange for Series A Notes acquired directly
      from the Company or an Affiliate thereof, it (1) could not, under
      Commission policy as in effect on the date of this Agreement, rely on the
      position of the Commission enunciated in MORGAN STANLEY AND CO., INC.
      (available June 5, 1991) and EXXON CAPITAL HOLDINGS CORPORATION (available
      May 13, 1988), as interpreted in the Commission's letter to SHEARMAN &
      STERLING dated July 2, 1993, and similar no-action letters (including, if
      applicable, any no-action letter obtained pursuant to clause (i) above),
      and (2) must comply with the registration and prospectus delivery
      requirements of the Act in connection with a secondary resale transaction
      and that such a secondary resale transaction must be covered by an
      effective registration statement containing the selling security holder
      information required by Item 507 or 508, as applicable, of Regulation S-K.

                (iii) Prior to effectiveness of the Exchange Offer Registration
      Statement, the Company and the Guarantors shall provide a supplemental
      letter to the Commission (A) stating that the Company and the Guarantors
      are registering the Exchange Offer in reliance on the position of the
      Commission enunciated in EXXON CAPITAL HOLDINGS CORPORATION (available May
      13, 1988), MORGAN STANLEY AND CO., INC. (available June 5, 1991) as
      interpreted in the Commission's letter to SHEARMAN & STERLING dated July
      2, 1993, and, if applicable, any no-action letter obtained pursuant to
      clause (i) above, (B) including a representation that neither the Company
      nor any Subsidiary Guarantor has entered into any arrangement or
      understanding with any Person to distribute the Series B Notes to be
      received in the Exchange Offer and that, to the best of the Company's and
      each Subsidiary Guarantor's information and belief, each Holder
      participating in the Exchange Offer is acquiring the Series B Notes in its
      ordinary course of business and has no arrangement or understanding with
      any Person to participate in the distribution of the Series B Notes
      received in the Exchange Offer and (C) any other undertaking or
      representation required by the Commission as set forth in any no-action
      letter obtained pursuant to clause (i) above, if applicable.

           (b) SHELF REGISTRATION STATEMENT. In connection with the Shelf
Registration Statement, the Company and the Guarantors shall:

                (i) comply with all the provisions of Section 6(c) below and use
their respective best efforts to effect such registration to permit the sale of
the Transfer Restricted Securities being sold in accordance with the intended
method or methods of distribution thereof (as indicated in the information
furnished to the Company pursuant to Section 4(b) hereof), and pursuant thereto
the Company and the Guarantors will prepare and file with the Commission a
Registration Statement relating to the registration on any appropriate form
under the Act, which form shall be available for the sale of the Transfer
Restricted Securities in accordance with the intended method or methods of
distribution thereof within the time periods and otherwise in accordance with
the provisions hereof.

                (ii) issue, upon the request of any Holder or purchaser of
Series A Notes covered by any Shelf Registration Statement contemplated by this
Agreement, Series B Notes having an aggregate principal amount equal to the
aggregate principal amount of Series A Notes sold pursuant to the Shelf
Registration Statement and surrendered to the Company for cancellation; the
Company shall register Series B Notes on the Shelf Registration Statement for
this purpose and issue the Series B Notes to the purchaser(s) of securities
subject to the Shelf Registration Statement in the names as such purchaser(s)
shall designate.

           (c) GENERAL PROVISIONS. In connection with any Registration Statement
and any related Prospectus required by this Agreement, the Company and the
Guarantors shall:

                                       8

<PAGE>

                (i) use their respective best efforts to keep such Registration
      Statement continuously effective and provide all requisite financial
      statements for the period specified in Section 3 or 4 of this Agreement,
      as applicable. Upon the occurrence of any event that would cause any such
      Registration Statement or the Prospectus contained therein (A) to contain
      an untrue statement of material fact or omit to state any material fact
      necessary to make the statements therein not misleading or (B) not to be
      effective and usable for resale of Transfer Restricted Securities during
      the period required by this Agreement, the Company and the Guarantors
      shall file promptly an appropriate amendment to such Registration
      Statement curing such defect, and, if Commission review is required, use
      their respective best efforts to cause such amendment to be declared
      effective as soon as practicable.

                (ii) prepare and file with the Commission such amendments and
      post-effective amendments to the applicable Registration Statement as may
      be necessary to keep such Registration Statement effective for the
      applicable period set forth in Section 3 or 4 hereof, as the case may be;
      cause the Prospectus to be supplemented by any required Prospectus
      supplement, and as so supplemented to be filed pursuant to Rule 424 under
      the Act, and to comply fully with Rules 424, 430A and 462, as applicable,
      under the Act in a timely manner; and comply in all material respects with
      the provisions of the Act with respect to the disposition of all
      securities covered by such Registration Statement during the applicable
      period in accordance with the intended method or methods of distribution
      by the sellers thereof set forth in such Registration Statement or
      supplement to the Prospectus;

                (iii) if (1) a Shelf Registration Statement is filed pursuant to
      Section 4 hereof, or (2) a Prospectus contained in an Exchange Offer
      Registration Statement filed pursuant to Section 3 hereof is required to
      be delivered under the Securities Act by any Participating Broker-Dealer
      who seeks to sell Series B Notes that are Transfer Restricted Securities,
      advise each Holder of the Transfer Restricted Securities included within
      the coverage of the Shelf Registration Statement or such Participating
      Broker-Dealer, as the case may be, promptly and, if requested by such
      Holder or Participating Broker-Dealer, as the case may be, confirm such
      advice in writing, (A) when the Prospectus or any Prospectus supplement or
      post-effective amendment has been filed, and, with respect to any
      applicable Registration Statement or any post-effective amendment thereto,
      when the same has become effective, (B) of any request by the Commission
      for amendments to the Registration Statement or amendments or supplements
      to the Prospectus or for additional information relating thereto, (C) of
      the issuance by the Commission of any stop order suspending the
      effectiveness of the Registration Statement under the Act or of the
      suspension by any state securities commission of the qualification of the
      Transfer Restricted Securities for offering or sale in any jurisdiction,
      or the initiation of any proceeding for any of the preceding purposes, and
      (D) during the period such Registration Statement is required to be
      effective as specified in Section 3 or 4 of this Agreement, as applicable,
      of the existence of any fact or the happening of any event that makes any
      statement of a material fact made in the Registration Statement, the
      Prospectus, any amendment or supplement thereto or any document
      incorporated by reference therein untrue, or that requires the making of
      any additions to or changes in the Registration Statement in order to make
      the statements therein not misleading, or that requires the making of any
      additions to or changes in the Prospectus in order to make the statements
      therein, in the light of the circumstances under which they were made, not
      misleading. If at any time the Commission shall issue any stop order
      suspending the effectiveness of the Registration Statement, or any state
      securities commission or other regulatory authority shall issue an order
      suspending the qualification or exemption from qualification of the
      Transfer Restricted Securities under state securities or Blue Sky laws,
      the Company and the Guarantors shall use their respective best efforts to
      obtain the withdrawal or lifting of such order at the earliest possible
      time;

                (iv) subject to Section 6(c)(i), if any fact or event
      contemplated by Section 6(c)(iii)(D) above shall exist or have occurred,
      prepare a supplement or post-effective amendment to the Registration
      Statement or related Prospectus or any document incorporated therein by
      reference or file any other

                                       9

<PAGE>

      required document so that, as thereafter delivered to the purchasers of
      Transfer Restricted Securities, the Prospectus will not contain an untrue
      statement of a material fact or omit to state any material fact necessary
      to make the statements therein, in the light of the circumstances under
      which they were made, not misleading;

                (v) if (1) a Shelf Registration Statement is filed pursuant to
      Section 4 hereof, or (2) a Prospectus contained in an Exchange Offer
      Registration Statement filed pursuant to Section 3 hereof is required to
      be delivered under the Securities Act by any Participating Broker-Dealer
      who seeks to sell Series B Notes that are Transfer Restricted Securities,
      before filing with the Commission copies of any Registration Statement or
      any Prospectus included therein or any amendments or supplements to any
      such Registration Statement or Prospectus (including all documents
      incorporated by reference after the initial filing of such Registration
      Statement), furnish to and offer each Holder of the Transfer Restricted
      Securities included within the coverage of the Shelf Registration
      Statement or such Participating Broker-Dealer, as the case may be, the
      managing underwriters (if any) and their respective counsel a reasonable
      opportunity to review copies and to participate in the preparation of all
      such documents proposed to be filed (including copies of any documents to
      be incorporated by reference thereto and all exhibits thereto) for a
      period of at least five Business Days prior to such filing, and the
      Company will include such information in such document prior to the filing
      thereof as such Holders or Participating Broker-Dealers, as the case may
      be, may reasonably request and will not file any such Registration
      Statement or Prospectus or any amendment or supplement to any such
      Registration Statement or Prospectus (including all such documents
      incorporated by reference) which shall be reasonably disapproved by such
      Holder, Participating Broker-Dealer or managing underwriters within five
      Business Days after the receipt thereof. A Holder, Participating
      Broker-Dealer or managing underwriter shall be deemed to have reasonably
      objected to such filing if such Registration Statement, amendment,
      Prospectus or supplement, as applicable, as proposed to be filed, contains
      an untrue statement of a material fact or omit to state any material fact
      necessary to make the statements therein not misleading or fails to comply
      with the applicable requirements of the Act;

                (vi) if (1) a Shelf Registration Statement is filed pursuant to
      Section 4 hereof, or (2) a Prospectus contained in an Exchange Offer
      Registration Statement filed pursuant to Section 3 hereof is required to
      be delivered under the Securities Act by any Participating Broker-Dealer
      who seeks to sell Series B Notes that are Transfer Restricted Securities,
      the Company shall (i) for a reasonable time period prior to the filing of
      such Registration Statement make reasonably available for inspection by
      the Holders of the Transfer Restricted Securities included within the
      coverage of the Shelf Registration Statement or such Participating
      Broker-Dealers, as the case may be, any underwriter (which term, for
      purpose of this Agreement, shall include a person deemed to be an
      underwriter within Section 2(11) of the Securities Act) participating in
      any disposition pursuant to the Registration Statement and any attorney,
      accountant or other agent retained by such Holders or Participating
      Broker-Dealers, as the case may be, or any such underwriter all relevant
      financial and other records, pertinent corporate documents and properties
      of the Company and the Guarantors and (ii) to cause the Company's and each
      of the Guarantor's officers, directors, employees, accountants and
      auditors to supply all information reasonably requested by such Holders or
      Participating Broker-Dealers, as the case may be, or any such underwriter,
      attorney, accountant or agent in connection with the Registration
      Statement, in each case, as shall be reasonably necessary to enable such
      persons to conduct a reasonable investigation within the meaning of
      Section 11 of the Securities Act, PROVIDED, HOWEVER, that the foregoing
      inspection and information gathering shall be coordinated by Holders and
      Participating Broker-Dealers holding in the aggregate at least 50% in
      aggregate principal amount of the sum of (I) the amount of Transfer
      Restricted Securities not yet sold under the Shelf Registration Statement
      and (II) the Transfer Restricted Securities held by such Participating
      Broker-Dealers on behalf of such parties, and by one counsel designated by
      and on behalf of such parties; and PROVIDED, FURTHER, that the Company may
      require each such parties to agree to maintain in confidence and not to
      disclose to any

                                       10

<PAGE>

      other person any information or records reasonably designated by the
      Company as being confidential, until such time as (A) such information
      becomes a matter of public record (whether by virtue of its inclusion in
      such Registration Statement or otherwise), (B) such person shall be
      required so to disclose such information pursuant to a subpoena or order
      of any court or other governmental agency or body having jurisdiction over
      the matter (subject to the requirements of such order, and only after such
      person shall have given the Company prompt written notice of such
      requirement) or (C) such information is required to be set forth in such
      Registration Statement or the prospectus included therein or in any
      amendment to such prospectus in order that such Registration Statement,
      prospectus, amendment or supplement, as the case may be, complies with
      applicable requirements of the federal securities laws and the rules and
      regulations of the Commission and does not contain an untrue statement of
      a material fact or omit to state therein a material fact required to be
      stated therein or necessary to make the statements therein not misleading
      in light of the circumstances then existing;

                (vii) if (1) a Shelf Registration Statement is filed pursuant to
      Section 4 hereof, or (2) a Prospectus contained in an Exchange Offer
      Registration Statement filed pursuant to Section 3 hereof is required to
      be delivered under the Securities Act by any Participating Broker-Dealer
      who seeks to sell Series B Notes that are Transfer Restricted Securities,
      furnish to each Holder of Transfer Restricted Securities included within
      the coverage of the Shelf Registration Statement or such Participating
      Broker-Dealer, as the case may be, without charge, at least one copy of
      the Registration Statement and of each post-effective amendment thereto
      and, if requested, all documents incorporated by reference therein and all
      exhibits (including exhibits incorporated therein by reference);

                (viii) if (1) a Shelf Registration Statement is filed pursuant
      to Section 4 hereof, or (2) a Prospectus contained in an Exchange Offer
      Registration Statement filed pursuant to Section 3 hereof is required to
      be delivered under the Securities Act by any Participating Broker-Dealer
      who seeks to sell Series B Notes that are Transfer Restricted Securities,
      deliver to each Holder of Transfer Restricted Securities included within
      the coverage of the Shelf Registration Statement or such Participating
      Broker-Dealer, as the case may be, without charge, as many copies of the
      Prospectus (including each preliminary prospectus) or each such Holder or
      such Participating Broker-Dealer, as the case may be, and any amendment or
      supplement thereto as such Persons reasonably may request; the Company and
      the Guarantors hereby consent to the use (in accordance with law) of the
      Prospectus and any amendment or supplement thereto by each such Holder or
      Participating Broker-Dealer, as the case may be, in connection with the
      offering and the sale of the Transfer Restricted Securities covered by the
      Prospectus or any amendment or supplement thereto;

                (ix) in the case of a Shelf Registration Statement, upon the
      request by Holders aggregating at least 20% in aggregate principal amount
      of the Transfer Restricted Securities outstanding, the Trustee or the
      managing underwriters (if any) in connection with such Shelf Registration
      Statement, enter into such agreements (including underwriting agreements)
      and make such representations and warranties and take all such other
      customary actions in connection therewith in order to expedite or
      facilitate the disposition of the Transfer Restricted Securities pursuant
      to such Shelf Registration Statement contemplated by this Agreement. In
      such connection, the Company and the Guarantors shall:

                (A) upon request of by Holders aggregating at least 20% in
           aggregate principal amount of the Transfer Restricted Securities
           outstanding, the Trustee or the managing underwriters (if any),
           furnish (or in the case of paragraphs (2) and (3), use its best
           efforts to cause to be furnished) to each Holder upon the
           effectiveness of the Shelf Registration Statement:

                      (1) a certificate, dated such date, signed on behalf of
                the Company and each Guarantor by (x) the President and (y) the
                Chief Financial Officer of the Company and such Guarantors,
                confirming, as of the date thereof, the matters set forth in
                Sections 9(a), 9(b) and 9(e) (the

                                       11

<PAGE>

                first clause of which may be limited to the Company's knowledge)
                and Section 6(dd) of the Purchase Agreement (except to the
                extent any exception to such matters are disclosed in such
                certificate) and such other similar matters as such Holders may
                reasonably request;

                      (2) an opinion, dated the date of effectiveness of the
                Shelf Registration Statement of counsel for the Company and the
                Guarantors covering matters similar to those set forth in
                paragraphs (f), (g), (h), (i) and (p) of Section 9 of the
                Purchase Agreement and such other matter as such Holder may
                reasonably request, and in any event including a statement to
                the effect that such counsel has participated in conferences
                with officers and other representatives of the Company and the
                Guarantors, representatives of the independent public
                accountants for the Company and the Guarantors and have
                considered the matters required to be stated therein and the
                statements contained therein, although such counsel has not
                independently verified the accuracy, completeness or fairness of
                such statements; and that such counsel advises that, on the
                basis of the foregoing (relying as to materiality to the extent
                such counsel deems appropriate upon the statements of officers
                and other representatives of the Company and the Guarantors and
                without independent check or verification), no facts came to
                such counsel's attention that caused such counsel to believe
                that the applicable Registration Statement, at the time such
                Registration Statement or any post-effective amendment thereto
                became effective, contained an untrue statement of a material
                fact or omitted to state a material fact required to be stated
                therein or necessary to make the statements therein not
                misleading, or that the Prospectus contained in such
                Registration Statement as of its date and contained an untrue
                statement of a material fact or omitted to state a material fact
                necessary in order to make the statements therein, in the light
                of the circumstances under which they were made, not misleading.
                Without limiting the foregoing, such counsel may state further
                that such counsel assumes no responsibility for, and has not
                independently verified, the accuracy, completeness or fairness
                of the financial statements, notes and schedules and other
                financial data included in any Registration Statement
                contemplated by this Agreement or the related Prospectus;

                      (3) a customary comfort letter, dated as of the date of
                effectiveness of the Shelf Registration Statement, from the
                Company's independent accountants, in the customary form and
                covering matters of the type customarily covered in comfort
                letters to underwriters in connection with underwritten
                offerings, and affirming the matters set forth in the comfort
                letters delivered pursuant to Section 9(k) of the Purchase
                Agreement; and

                (B) deliver such other documents and certificates as may be
           reasonably requested by Holders aggregating at least 20% in aggregate
           principal amount of the Transfer Restricted Securities outstanding,
           the Trustee or the managing underwriters (if any) to evidence
           compliance with the matters covered in clause (A) above and with any
           customary conditions contained in any agreement entered into by the
           Company and the Guarantors pursuant to this clause (ix);

                (x) in the case of the Exchange Offer, if requested by any
      Participating Broker-Dealer, the Company shall furnish (or in the case of
      paragraphs (B) and (C), use its best efforts to cause to be furnished) to
      each Participating Broker-Dealer, upon Consummation of the Exchange Offer:

                (A) a certificate, dated the date of Consummation of the
           Exchange Offer, signed on behalf of the Company and each Guarantor by
           (x) the President and (y) the Chief Financial Officer of the Company
           and such Guarantors, confirming, as of the date thereof, the matters
           set forth in Sections 9(a), 9(b) and 9(e) (the first clause of which
           may be limited to the Company's knowledge) and Section 6(dd) of the
           Purchase Agreement (except to the extent any exception to such
           matters are

                                       12

<PAGE>

           disclosed in such certificate) and such other similar matters as such
           Participating Broker-Dealers may reasonably request;

                (B) an opinion, dated the date of Consummation of the Exchange
           Offer, of counsel for the Company and the Guarantors covering matters
           similar to those set forth in paragraphs (f), (g), (h), (i) and (p)
           of Section 9 of the Purchase Agreement with such changes as are
           customary in connection with the preparation of the Registration
           Statement; and

                (C) a customary comfort letter, dated the date of Consummation
           of the Exchange Offer, from the Company's independent accountants, in
           the customary form and covering matters of the type customarily
           covered in comfort letters to underwriters in connection with
           underwritten offerings, and affirming the matters set forth in the
           comfort letters delivered pursuant to Section 9(k) of the Purchase
           Agreement.

                (xi) prior to any public offering of Transfer Restricted
           Securities, cooperate with the selling Holders and their counsel in
           connection with the registration and qualification of the Transfer
           Restricted Securities under the securities or Blue Sky laws of such
           jurisdictions as the selling Holders may request and do any and all
           other acts or things necessary or advisable to enable the disposition
           in such jurisdictions of the Transfer Restricted Securities covered
           by the applicable Registration Statement; PROVIDED, HOWEVER, that
           neither the Company nor any Subsidiary Guarantor shall be required to
           register or qualify as a foreign corporation where it is not now so
           qualified or to take any action that would subject it to the service
           of process in suits or to taxation, other than as to matters and
           transactions relating to the Registration Statement, in any
           jurisdiction where it is not now so subject;

                (xii) in connection with any sale of Transfer Restricted
           Securities that will result in such securities no longer being
           Transfer Restricted Securities, cooperate with the Holders to
           facilitate the timely preparation and delivery of certificates
           representing Transfer Restricted Securities to be sold and not
           bearing any restrictive legends; and to register such Transfer
           Restricted Securities in such denominations and such names as the
           selling Holders may request at least two Business Days prior to such
           sale of Transfer Restricted Securities;

                (xiii) use their respective best efforts to cause the
           disposition of the Transfer Restricted Securities covered by the
           Registration Statement to be registered with or approved by such
           other governmental agencies or authorities as may be necessary to
           enable the seller or sellers thereof to consummate the disposition of
           such Transfer Restricted Securities, subject to the proviso contained
           in clause (xii) above;

                (xiv) provide a CUSIP number for all Transfer Restricted
           Securities not later than the effective date of a Registration
           Statement covering such Transfer Restricted Securities and provide
           the Trustee under the Indenture with printed certificates for the
           Transfer Restricted Securities which are in a form eligible for
           deposit with the Depository Trust Company;

                (xv) otherwise use their respective best efforts to comply in
           all material respects with all applicable rules and regulations of
           the Commission, and make generally available to its security holders
           with regard to any applicable Registration Statement, as soon as
           practicable, a consolidated earnings statement meeting the
           requirements of Rule 158 (which need not be audited) covering a
           twelve-month period beginning after the effective date of the
           Registration Statement (as such term is defined in paragraph (c) of
           Rule 158 under the Act); and

                (xvi) cause the Indenture to be qualified under the TIA not
           later than the effective date of the first Registration Statement
           required by this Agreement and, in connection therewith, cooperate
           with

                                       13
<PAGE>


      the Trustee and the Holders to effect such changes to the Indenture as may
      be required for such Indenture to be so qualified in accordance with the
      terms of the TIA; and execute and use its best efforts to cause the
      Trustee to execute, all documents that may be required to effect such
      changes and all other forms and documents required to be filed with the
      Commission to enable such Indenture to be so qualified in a timely manner.

         (d) RESTRICTIONS ON HOLDERS. Each Holder agrees by acquisition of a
Transfer Restricted Security that, upon receipt of the notice referred to in
Section 6(c)(iii)(C) or any notice from the Company of the existence of any fact
of the kind described in Section 6(c)(iii)(D) hereof (in each case, a
"SUSPENSION NOTICE"), such Holder will forthwith discontinue disposition of
Transfer Restricted Securities pursuant to the applicable Registration Statement
until (i) such Holder has received copies of the supplemented or amended
Prospectus contemplated by Section 6(c)(iv) hereof, or (ii) such Holder is
advised in writing by the Company that the use of the Prospectus may be resumed,
and has received copies of any additional or supplemental filings that are
incorporated by reference in the Prospectus (in each case, the "RECOMMENCEMENT
DATE"). Each Holder receiving a Suspension Notice hereby agrees that it will
either (i) destroy any Prospectuses, other than permanent file copies, then in
such Holder's possession which have been replaced by the Company with more
recently dated Prospectuses or (ii) deliver to the Company (at the Company's
expense) all copies, other than permanent file copies, then in such Holder's
possession of the Prospectus covering such Transfer Restricted Securities that
was current at the time of receipt of the Suspension Notice. The time period
regarding the effectiveness of such Registration Statement set forth in Section
3 or 4 hereof, as applicable, shall be extended by a number of days equal to the
number of days in the period from and including the date of delivery of the
Suspension Notice to the date of delivery of the Recommencement Date.

SECTION 7.      REGISTRATION EXPENSES

         (a) Subject to Section 10, all expenses incident to the Company's and
the Guarantors' performance of or compliance with this Agreement will be borne
by the Company, regardless of whether a Registration Statement becomes
effective, including without limitation: (i) all registration and filing fees
and expenses; (ii) all fees and expenses of compliance with federal securities
and state Blue Sky or securities laws; (iii) all expenses of printing (including
printing certificates for the Series B Notes to be issued in the Exchange Offer
and printing of Prospectuses), messenger and delivery services and telephone;
(iv) all fees and disbursements of counsel for the Company, the Guarantors and
the Holders of Transfer Restricted Securities; (v) all application and filing
fees in connection with listing the Series B Notes on a national securities
exchange or automated quotation system pursuant to the requirements hereof; and
(vi) all fees and disbursements of independent certified public accountants of
the Company and the Guarantors (including the expenses of any special audit and
comfort letters required by or incident to such performance).

         Subject to Section 10, the Company will, in any event, bear its and the
Guarantors' internal expenses (including, without limitation, all salaries and
expenses of its officers and employees performing legal or accounting duties),
the expenses of any annual audit and the fees and expenses of any Person,
including special experts, retained by the Company or the Guarantors.

         (b) In connection with any Registration Statement required by this
Agreement (including, without limitation, the Exchange Offer Registration
Statement and the Shelf Registration Statement), the Company and the Guarantors
will reimburse the Initial Purchasers and the Holders of Transfer Restricted
Securities who are tendering Series A Notes in the Exchange Offer and/or selling
or reselling Series A Notes or Series B Notes pursuant to the "Plan of
Distribution" contained in the Exchange Offer Registration Statement or the
Shelf Registration Statement, as applicable, for the reasonable fees and
disbursements of

                                       14

<PAGE>

not more than one counsel, who shall be Sullivan & Cromwell, unless another firm
shall be chosen by the Holders of a majority in principal amount of the Transfer
Restricted Securities for whose benefit such Registration Statement is being
prepared.

SECTION 8.      INDEMNIFICATION

         (a) The Company and the Guarantors agree, jointly and severally, to
indemnify and hold harmless each Holder, its directors, officers and each
Person, if any, who controls such Holder (within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act), from and against any and all losses,
claims, damages, liabilities, judgments, (including without limitation, any
legal or other expenses incurred in connection with investigating or defending
any matter, including any action that could give rise to any such losses,
claims, damages, liabilities or judgments) caused by any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement, preliminary prospectus or Prospectus (or any amendment or supplement
thereto) provided by the Company to any Holder or any prospective purchaser of
Series B Notes or registered Series A Notes, or caused by any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, except insofar as
such losses, claims, damages, liabilities or judgments are caused by an untrue
statement or omission or alleged untrue statement or omission that is based upon
information relating to any of the Holders furnished in writing to the Company
by any of the Holders; and PROVIDED, that the Company and each Guarantor shall
not be liable to any Holder under the indemnity agreement in this subsection (a)
with respect to any preliminary prospectus to the extent that any such loss,
claim, damage or liability of such Holder results from the fact that such Holder
sold Series A Notes to a person as to whom it shall be established that there
was not sent or given, at or prior to the written confirmation of such sale, a
copy of the prospectus or of the prospectus as then amended or supplemented in
any case where such delivery is required by the Act if the Company or any
Guarantor has previously furnished copies thereof in sufficient quantity to such
Holder and the loss, claim, damage or liability of such Holder results from an
untrue statement or omission of a material fact contained in the preliminary
prospectus which was identified in writing at such time to such Holder and
corrected in the prospectus.

         (b) Each Holder of Transfer Restricted Securities agrees, severally and
not jointly, to indemnify and hold harmless the Company and the Guarantors, and
their respective directors and officers, and each person, if any, who controls
(within the meaning of Section 15 of the Act or Section 20 of the Exchange Act)
the Company, or the Guarantors to the same extent as the foregoing indemnity
from the Company and the Guarantors set forth in Section 8(a) above, but only
with reference to information relating to such Holder furnished in writing to
the Company by such Holder expressly for use in any Registration Statement. In
no event shall any Holder, its directors, officers or any Person who controls
such Holder be liable or responsible for any amount in excess of the amount by
which the total amount received by such Holder with respect to its sale of
Transfer Restricted Securities pursuant to a Registration Statement exceeds (i)
the amount paid by such Holder for such Transfer Restricted Securities and (ii)
the amount of any damages that such Holder, its directors, officers or any
Person who controls such Holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission.

         (c) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"INDEMNIFIED PARTY"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "INDEMNIFYING PERSON") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 8(a) and 8(b), a Holder shall not be required to assume the
defense of such action pursuant to this Section 8(c), but may employ separate
counsel and participate in the defense thereof, but the

                                       15

<PAGE>

fees and expenses of such counsel, except as provided below, shall be at the
expense of the Holder). Any indemnified party shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of the indemnified
party unless (i) the employment of such counsel shall have been specifically
authorized in writing by the indemnifying party, (ii) the indemnifying party
shall have failed to assume the defense of such action or employ counsel
reasonably satisfactory to the indemnified party or (iii) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the indemnifying party, and the indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the indemnified party).
In any such case, the indemnifying party shall not, in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) for all indemnified parties and all such fees and
expenses shall be reimbursed as they are incurred. Such firm shall be designated
in writing by a majority of the Holders, in the case of the parties indemnified
pursuant to Section 8(a), and by the Company and Guarantors, in the case of
parties indemnified pursuant to Section 8(b). The indemnifying party shall
indemnify and hold harmless the indemnified party from and against any and all
losses, claims, damages, liabilities and judgments by reason of any settlement
of any action (i) effected with its written consent or (ii) effected without its
written consent if the settlement is entered into more than twenty business days
after the indemnifying party shall have received a request from the indemnified
party for reimbursement for the fees and expenses of counsel (in any case where
such fees and expenses are at the expense of the indemnifying party) and, prior
to the date of such settlement, the indemnifying party shall have failed to
comply with such reimbursement request. No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement or
compromise of, or consent to the entry of judgment with respect to, any pending
or threatened action in respect of which the indemnified party is or could have
been a party and indemnity or contribution may be or could have been sought
hereunder by the indemnified party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability on claims that are or could have been the subject matter of such
action and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of the indemnified party.

         (d) To the extent that the indemnification provided for in this Section
8 is unavailable to an indemnified party in respect of any losses, claims,
damages, liabilities or judgments referred to therein, then each indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities or judgments (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Guarantors, on the one hand, and the Holders, on the other hand, from their sale
of Transfer Restricted Securities or (ii) if the allocation provided by clause
8(d)(i) is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause 8(d)(i) above
but also the relative fault of the Company and the Guarantors, on the one hand,
and of the Holder, on the other hand, in connection with the statements or
omissions which resulted in such losses, claims, damages, liabilities or
judgments, as well as any other relevant equitable considerations. The relative
fault of the Company and the Guarantors, on the one hand, and of the Holder, on
the other hand, shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or such Subsidiary Guarantor, on the one hand, or by the Holder, on the
other hand, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

         The Company, the Guarantors and each Holder agree that it would not be
just and equitable if contribution pursuant to this Section 8(d) were determined
by pro rata allocation (even if the Holders were

                                       16

<PAGE>

treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to in the
immediately preceding paragraph. The amount paid or payable by an indemnified
party as a result of the losses, claims, damages, liabilities or judgments
referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses incurred
by such indemnified party in connection with investigating or defending any
matter, including any action that could have given rise to such losses, claims,
damages, liabilities or judgments. Notwithstanding the provisions of this
Section 8(d), no Holder, its directors, its officers or any Person, if any, who
controls such Holder shall be required to contribute, in the aggregate, any
amount in excess of the amount by which the total received by such Holder with
respect to the sale of Transfer Restricted Securities pursuant to a Registration
Statement exceeds (i) the amount paid by such Holder for such Transfer
Restricted Securities and (ii) the amount of any damages which such Holder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Holders' obligations to contribute pursuant to this
Section 8(d) are several in proportion to the respective principal amount of
Transfer Restricted Securities held by each Holder hereunder and not joint.

SECTION 9.      RULE 144A and RULE 144

           The Company and each Subsidiary Guarantor agrees with each Holder,
for so long as any Transfer Restricted Securities remain outstanding and during
any period in which the Company or such Subsidiary Guarantor (i) is not subject
to Section 13 or 15(d) of the Exchange Act, to make available, upon request of
any Holder, to such Holder or beneficial owner of Transfer Restricted Securities
in connection with any sale thereof and any prospective purchaser of such
Transfer Restricted Securities designated by such Holder or beneficial owner,
the information required by Rule 144A(d)(4) under the Act in order to permit
resales of such Transfer Restricted Securities pursuant to Rule 144A, and (ii)
is subject to Section 13 or 15 (d) of the Exchange Act, to make all filings
required thereby in a timely manner in order to permit resales of such Transfer
Restricted Securities pursuant to Rule 144.

SECTION 10.     UNDERWRITTEN REGISTRATIONS.

         (a) SELECTION OF UNDERWRITERS. If any of the Transfer Restricted
Securities covered by any Shelf Registration Statement are to be sold in an
underwritten offering, the investment banker or investment bankers and manager
or managers that will administer the offering will be selected by the Holders of
a majority in aggregate principal amount of such Transfer Restricted Securities
included in such offering, provided that such designated managing underwriter or
underwriters is or are reasonably acceptable to the Company.

           (b) PARTICIPATION OF HOLDERS. No person may participate in any
underwritten registration hereunder unless such person (i) agrees to sell such
person's Transfer Restricted Securities on the basis reasonably provided in any
underwriting agreements approved by the persons entitled hereunder to approve
such arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting agreements.

                                       17

SECTION 11.     MISCELLANEOUS

         (a) REMEDIES. The Company and the Guarantors acknowledge and agree that
any failure by the Company and/or the Guarantors to comply with their respective
obligations under Sections 3 and 4 hereof may result in material irreparable
injury to the Initial Purchasers or the Holders for which there is no adequate
remedy at law, that it will not be possible to measure damages for such injuries
precisely and that, in the event of any such failure, the Initial Purchasers or
any Holder may obtain such relief as may be required to specifically enforce the
Company's and the Guarantors' obligations under Sections 3 and 4 hereof. The
Company and the Guarantors further agree to waive the defense in any action for
specific performance that a remedy at law would be adequate.

         (b) NO INCONSISTENT AGREEMENTS. Neither the Company nor any Subsidiary
Guarantor will, on or after the date of this Agreement, enter into any agreement
with respect to its securities that is inconsistent with the rights granted to
the Holders in this Agreement or otherwise conflicts with the provisions hereof.
Neither the Company nor any Subsidiary Guarantor has previously entered into any
agreement granting any registration rights with respect to the Series A Notes to
any Person. The rights granted to the Holders hereunder do not in any way
conflict with and are not inconsistent with the rights granted to the holders of
the Company's and the Guarantors' securities under any agreement in effect on
the date hereof.

         (c) AMENDMENTS AND WAIVERS. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this Section 11(c)(i), the Company has obtained the written consent
of Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Company has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Company or its Affiliates). Notwithstanding the foregoing, a waiver or consent
to departure from the provisions hereof that relates exclusively to the rights
of Holders whose Transfer Restricted Securities are being tendered pursuant to
the Exchange Offer, and that does not affect directly or indirectly the rights
of other Holders whose Transfer Restricted Securities are not being tendered
pursuant to such Exchange Offer, may be given by the Holders of a majority of
the outstanding principal amount of Transfer Restricted Securities subject to
such Exchange Offer.

         (d) THIRD PARTY BENEFICIARY. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent they may
deem such enforcement necessary or advisable to protect its rights or the rights
of Holders hereunder.

         (e) NOTICES. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air
courier guaranteeing overnight delivery:

of and be binding upon the successors and assigns of each of the parties,
including without limitation and without the need for an express assignment,
subsequent Holders; PROVIDED, that nothing herein shall be deemed to permit any
assignment, transfer or other disposition of Transfer Restricted Securities in
violation of the terms hereof or of the Purchase Agreement or the Indenture. If
any transferee of any Holder shall acquire Transfer Restricted Securities in any
manner, whether by operation of law or otherwise, such Transfer Restricted
Securities shall be held subject to all of the terms of this Agreement, and by
taking and holding such Transfer Restricted Securities such Person shall be
conclusively deemed to have agreed to be bound by and to perform all of the
terms and provisions of this Agreement, including the restrictions on resale set
forth in this Agreement and, if applicable, the Purchase Agreement, and such
Person shall be entitled to receive the benefits hereof.

         (g) COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

         (h) HEADINGS. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE
CONFLICT OF LAW RULES THEREOF.

         (j) SEVERABILITY. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

final expression of their agreement and intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein. There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein
with respect to the registration rights granted with respect to the Transfer
Restricted Securities. This Agreement supersedes all prior agreements and
understandings between the parties with respect to such subject matter.

                          REGISTRATION RIGHTS AGREEMENT

          REGISTRATION RIGHTS AGREEMENT, dated as of August 17, 1999, by and
among Concentra Managed Care, Inc., a Delaware corporation (the "COMPANY"), the
several persons named in Schedule I hereto (collectively, the "SCHEDULE I
PURCHASERS") and the person named in Schedule II hereto (the "CHASE PURCHASER"),
each of whom has agreed to purchase the Company's 14% Senior Discount Debentures
due 2010 (the "DEBENTURES") pursuant to the Purchase Agreement (as defined
below). The Schedule I Purchasers and the Chase Purchaser are herein sometimes
referred to collectively as the "PURCHASERS."

          WHEREAS, this Agreement is made pursuant to the Purchase Agreement as
of dated August 17, 1999 (the "PURCHASE AGREEMENT") by and among the Company and
the Purchasers and in order to induce the Purchasers to purchase the Debentures,
the Company has agreed to provide the registration rights set forth in this
Agreement.

          NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements herein contained, the parties hereto hereby agree as
follows:

          1. CERTAIN DEFINITIONS. Capitalized terms used herein and not
otherwise defined shall have the meaning assigned to them in the Indenture,
dated as of August 17, 1999, between the Company and United States Trust Company
of New York, as Trustee, relating to the Debentures (the "INDENTURE"). In

     other federal agency at the time administering the Securities Act.

          "EXCHANGE ACT" shall mean the Securities Exchange Act of 1934 or any

<PAGE>



          2. DEMAND REGISTRATION.

          (a) At any time after the Issue Date, the holders of a majority in
aggregate principal amount at maturity of the outstanding Debentures may request
the Company to register under the Securities Act all or any portion of the
Debentures held by such requesting holder or holders for sale in the manner
specified in such notice. At any time after the third anniversary of the Issue
Date, the Chase Purchaser may make one request to the Company to register under
the Securities Act all of the Debentures held by such requesting holder for sale
in the manner specified in such notice.

          (b) Promptly following receipt of any notice under this Section 2, the
Company shall immediately notify any holders of Debentures from whom notice has
not been received and shall use its best efforts to register as soon as possible
under the Securities Act, for public sale in accordance with the method of
disposition specified in such notice from the original requesting holders, the
principal amount at maturity of the Debentures specified in such notice (and in
any notices received from other holders of Debentures within 20 days after their
receipt of such notice from the Company). The original requesting holders may
choose the managing underwriter (which shall be a nationally recognized
investment banking firm), subject to the consent of the Company (which shall not
be unreasonably withheld). Notwithstanding anything to the contrary contained
herein, the obligation of the Company under this Section 2 shall be deemed
satisfied only when a registration statement covering all of the principal
amount at maturity of the Debentures specified in notices received as aforesaid,
for sale in accordance with the method of disposition specified by the
requesting holder, shall have become effective.

          (c) The Company shall not be obligated to file a registration
statement relating to any registration request under this Section 2:

               (i) if with respect thereto the managing underwriter, the
          Commission, the Securities Act or the rules and regulations
          thereunder, or the form on which the registration statement is to be
          filed, would require the conduct of an audit other than the regular
          audit conducted by the Company at the end of its fiscal year, in which
          case the filing may be delayed until the completion of such audit (and
          the Company shall, upon request of the parties demanding registration
          pursuant to this Section 2, use its reasonable efforts to cause such
          audit to be completed expeditiously and without unreasonable delay);

               (ii) if the Company is in possession of material non-public
          information and the Board determines in good faith that disclosure of
          such information would not be in the best interests of the Company and
          its stockholders, in which case the filing of the registration
          statement may be delayed until the earlier of (i) the second business
          day after such conditions shall have ceased to exist and (ii) the

                                       2

<PAGE>


          90th day after receipt by the Company of the written request from the
          holders specified in paragraph (a) above; or

               (iii) within a period of 180 days (or such lesser period as the
          managing underwriters in an underwritten offering may permit) after
          the effective date of any other registration statement relating to any
          securities of the Company.

          3. REGISTRATION PROCEDURES. If and whenever the Company is required by
the provisions of Section 2 hereof to use its best efforts to effect the
registration of any of the Debentures under the Securities Act, the Company
will, as expeditiously as possible:

          (a) in accordance with the Securities Act and all applicable rules and
     regulations, prepare (and afford counsel for the selling holders reasonable
     opportunity to review and comment thereon) and file with the Commission a
     registration statement with respect to such securities and use its best
     efforts to cause such registration statement to become and remain effective
     for the period of the distribution contemplated thereby (determined as
     hereinafter provided);

          (b) prepare (and afford counsel for the selling holders reasonable
     opportunity to review and comment thereon) and file with the Commission
     such amendments and supplements to such registration statement and the
     prospectus used in connection therewith and any documents incorporated by
     reference therein and file such other documents as may be necessary to keep
     such registration statement effective for the period specified in paragraph
     (a) above and to comply with the provisions of the Securities Act with
     respect to the disposition of all Debentures covered by such registration
     statement in accordance with the sellers' intended method of disposition
     set forth in such registration statement for such period;

          (c) furnish to each seller and to each underwriter such number of
     copies of the registration statement and the prospectus included therein
     (including each preliminary prospectus), and all amendments, supplements,
     and exhibits thereto, and such other documents as such persons may
     reasonably request in order to facilitate the public sale or other
     disposition of the Debentures covered by such registration statement (and
     the Company hereby consents to the use of any such prospectus, together
     with such supplements and amendments, by the sellers and underwriters, if
     any, in connection with the offer and sale covered thereby);

          (d) use its best efforts to register or qualify the Debentures covered
     by such registration statement under the securities or blue sky laws of
     such jurisdictions as the sellers of Debentures or, in the case of an
     underwritten offering, the managing underwriter, shall reasonably request
     (provided that the Company will not be required to (i) qualify generally to
     do business in any jurisdiction where it would not otherwise be

                                       3

<PAGE>


     required to qualify but for this paragraph (d), (ii) subject itself to
     taxation in any such jurisdiction or (iii) consent to general service of
     process in any jurisdiction);

          (e) immediately notify each seller under such registration statement
     and each underwriter, (i) when such registration statement or any
     post-effective amendment or supplement thereto becomes effective or a
     supplement to any prospectus forming a part of such registration statement
     has been filed; (ii) of the issuance by the Commission or any state
     securities authority of any stop order, injunction or other order or
     requirement suspending the effectiveness of such registration statement
     (and the Company shall use best efforts to prevent the initiation of
     proceedings for, prevent the entry of and/or remove such order or
     requirement); (iii) of the happening of any event as a result of which such
     registration statement, as then in effect, the prospectus contained therein
     or any document incorporated by reference therein includes an untrue
     statement of a material fact or omits to state any material fact required
     to be stated therein or necessary to make the statements therein not
     misleading in the light of the circumstances then existing; or (iv) of any
     request by the Commission for the amending or supplementing of such
     registration statement or prospectus or for additional information;

          (f) use its best efforts to furnish, at the request of any seller, on
     the date that Debentures are delivered to the underwriters for sale
     pursuant to such registration, if such securities are being sold through
     underwriters, or on the date that the registration statement becomes
     effective, if such securities are not being sold through underwriters: (i)
     an opinion dated such date of counsel representing the Company for the
     purposes of such registration, addressed to the underwriters, if any, and
     to such seller, stating that such registration statement has become
     effective under the Securities Act and that (A) to the best knowledge of
     such counsel, no stop order suspending the effectiveness thereof has been
     issued and no proceedings for that purpose have been instituted or are
     pending or contemplated under the Securities Act, (B) the registration
     statement, the related prospectus, and each amendment or supplement
     thereof, comply as to form in all material respects with the requirements
     of the Securities Act and the applicable rules and regulations of the
     Commission thereunder (except that such counsel need express no opinion as
     to financial statements, the notes thereto, and the financial schedules and
     other financial and statistical data contained therein) and (C) to such
     other effects as may reasonably be requested by counsel for the
     underwriters or by such seller or its counsel, and (ii) a letter dated such
     date from the independent public accountants retained by the Company,
     addressed to the underwriters, if any, and to such sellers stating that
     they are independent public accountants within the meaning of the
     Securities Act and that, in the opinion of such accountants, the financial
     statements of the Company included in the registration statement or the
     prospectus, or any amendment or supplement thereof, comply as to form in
     all material respects with the applicable accounting requirements of the
     Securities Act, and such letter shall additionally cover such other
     financial matters (including information as to the period ending no more
     than five business days prior to

                                       4

<PAGE>


     the date of such letter) with respect to the registration in respect of
     which such letter is being given as such underwriters or sellers may
     reasonably request;

          (g) take such actions as may be necessary or appropriate to obtain a
     CUSIP number (if none exists) for the Debentures and make all filings and
     secure all approvals required pursuant to the regulations of the National
     Association of Securities Dealers, Inc. in connection with such
     registration;

          (h) use its best efforts to comply with all applicable rules and
     regulations of the Commission, and make available to any holder of
     Debentures as soon as reasonably practicable (but not more than 15 months)
     after the effective date of the registration statement, an earnings
     statement which shall satisfy the provisions of Section 11(a) of the
     Securities Act and the rules and regulations promulgated thereunder; and

          (i) make available for inspection by each seller, any underwriter
     participating in any distribution pursuant to such registration statement,
     and any attorney, accountant or other agent retained by such seller or
     underwriter, all financial and other records, pertinent corporate documents
     and properties of the Company, and cause the Company's officers, directors
     and employees to supply all information reasonably requested by any such
     seller, underwriter, attorney, accountant or agent in connection with such
     registration statement and permit such seller, attorney, accountant or
     agent to participate in the preparation of such registration statement.

For purposes of paragraphs (a) and (b) above and of Section 2(c) hereof, the
period of distribution of Debentures in a firm commitment underwritten public
offering shall be deemed to extend until each underwriter has completed the
distribution of all Debentures purchased by it, and the period of distribution
of Debentures in any other registration shall be deemed to extend until the
earlier of the sale of all Debentures covered thereby or six months after the
effective date thereof.

          In connection with each registration hereunder, the selling holders of
Debentures will furnish to the Company in writing such information with respect
to themselves and the proposed distribution by them as shall be reasonably
necessary in order to assure compliance with federal and applicable state
securities laws.

          In connection with each registration pursuant to Section 2 hereof
covering an underwritten public offering, the Company agrees to enter into a
written agreement with the managing underwriter selected in the manner herein
provided in such form and containing such provisions as are customary in the
securities business for such an arrangement between major underwriters and
companies of the Company's size and investment stature; PROVIDED, HOWEVER, that
such agreement shall not contain any such provision applicable to the Company
which is inconsistent with the provisions hereof and PROVIDED, FURTHER, HOWEVER,
that the time and place of

                                       5

<PAGE>


the closing under said agreement shall be as mutually agreed upon among the
Company, such managing underwriter and the selling holders of Debentures.

          4. EXPENSES. All expenses incurred by the Company in complying with
Section 2 hereof, including, without limitation, all registration, listing and
filing fees, printing expenses, fees and disbursements of counsel and
independent public accountants for the Company (including with respect to any
special audit or "cold comfort" letters), fees of the National Association of
Securities Dealers, Inc., transfer taxes and fees of transfer agents and
registrars, as well as reasonable fees and out-of pocket expenses of not more
than one counsel for all the Purchasers but excluding any Selling Expenses, are
herein called "REGISTRATION EXPENSES." All underwriting discounts and selling
commissions applicable to the sale of Debentures are herein called "SELLING
EXPENSES."

          The Company will pay all Registration Expenses in connection with each
registration statement filed pursuant to Section 2 hereof. All Selling Expenses
in connection with any registration statement filed pursuant to Section 2 hereof
shall be borne by the participating sellers in proportion to the principal
amount at maturity of Debentures sold by each, or by such persons as they may
agree.

          5. INDEMNIFICATION. In the event of a registration of any of the
Debentures under the Securities Act pursuant to Section 2 hereof, the Company
will indemnify and hold harmless, to the fullest extent permitted by law, each
seller of such Debentures thereunder, each underwriter of Debentures thereunder,
each of their respective affiliates, each of their and their affiliates'
respective directors, officers, fiduciaries, trustees, agents, employees,
stockholders, general and limited partners and members, and each other person,
if any, who controls such seller or underwriter within the meaning of the
Securities Act, against any losses, claims, damages or liabilities, joint or
several, actions or proceedings (whether commenced or threatened) in respect
thereof (all of the foregoing, collectively, "CLAIMS") and expenses (including
fees and expenses of counsel, and amounts paid in any settlement effected with
the Company's consent, which consent shall not be unreasonably withheld or
delayed) to which such indemnified party may become subject under the Securities
Act or otherwise, insofar as such Claims or expenses arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any registration statement under which such Debentures were
registered under the Securities Act pursuant to Section 2, any preliminary
prospectus, summary or final prospectus contained therein, or any amendment or
supplement of any thereof, or any documents incorporated by reference therein,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse each such indemnified
party for any legal or other expenses incurred by them in connection with
investigating or defending any such Claim; PROVIDED, HOWEVER, that the Company
will not be liable to any such indemnified party if and to the extent that any
such Claim or expense arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission so made in conformity

                                       6

<PAGE>


with information pertaining to such indemnified party furnished by such
indemnified party in writing specifically for use in such registration statement
or prospectus.

          In the event of a registration of any of the Debentures under the
Securities Act pursuant to Section 2 hereof, each seller of such Debentures
thereunder, severally and not jointly, will indemnify and hold harmless, to the
fullest extent permitted by law, the Company and each person, if any, who
controls the Company within the meaning of the Securities Act, each officer of
the Company who signs the registration statement, each director of the Company,
each underwriter and each person who controls any underwriter within the meaning
of the Securities Act, each other holder selling Debentures under such
registration statement and each affiliate, officer, director, fiduciary,
trustee, agent, employee, stockholder, general or limited partner or member of
such selling holder against all Claims and expenses (including fees and expenses
of counsel, and amounts paid in any settlement effected with the indemnifying
party's consent, which consent shall not be unreasonably withheld or delayed) to
which the Company or such officer or director or underwriter or controlling
person may become subject under the Securities Act or otherwise, insofar as such
Claims or expenses arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the registration
statement under which such Debentures were registered under the Securities Act
pursuant to Section 2, any preliminary prospectus, summary or final prospectus
contained therein, or any amendment or supplement of any thereof, or any
documents incorporated by reference therein, or arise out of or are based upon
the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
will reimburse the Company and each such indemnified party for any legal or
other expenses incurred by them in connection with investigating or defending
any such Claim; PROVIDED, HOWEVER, that such seller will be liable hereunder to
any such indemnified party if and only to the extent that any such Claim or
expense arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in reliance upon and in
conformity with information pertaining to such seller, as such, furnished in
writing to the Company by such seller specifically for use in such registration
statement or prospectus; PROVIDED, FURTHER, HOWEVER, that the liability of each
seller hereunder shall be limited to the proceeds (net of underwriting discounts
and commissions) received by such seller from the sale of Debentures covered by
such registration statement.

          Promptly after receipt by an indemnified party hereunder of notice of
the commencement of any action, such indemnified party shall, if a claim in
respect thereof is to be made against the indemnifying party hereunder, notify
the indemnifying party in writing thereof, but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
such indemnified party under this Section 5 except to the extent such
indemnifying party is materially prejudiced thereby, and in any event will not
relieve such indemnifying party from any liability which it may have to any
indemnified party other than under this Section 5. In case any such action shall
be brought against any indemnified party and it shall notify the indemnifying
party of the commencement thereof, the indemnifying party shall be entitled to
participate in and, to the extent it shall wish, to assume and undertake the
defense thereof with

                                       7

<PAGE>


counsel satisfactory to such indemnified party, and, after notice from the
indemnifying party to such indemnified party of its election so to assume and
undertake the defense thereof, the indemnifying party shall not be liable to
such indemnified party under this Section 5 for any legal expenses subsequently
incurred by such indemnified party in connection with the defense thereof other
than reasonable costs of investigation and of liaison with counsel so selected;
PROVIDED, HOWEVER, that, if the defendants in any such action include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be reasonable defenses available to it
which are different from or additional to those available to the indemnifying
party, or if the interests of the indemnified party reasonably may be deemed to
conflict with the interests of the indemnifying party, or if the indemnifying
party shall not diligently continue such defense in good faith, the indemnified
party shall have the right to select a separate counsel and to assume such legal
defenses and otherwise to participate in the defense of such action, with the
expenses and fees of such separate counsel and other expenses related to such
participation to be reimbursed by the indemnifying party as incurred.

          Notwithstanding the foregoing, any indemnified party shall have the
right to retain its own counsel in any such action, but except as set forth
above the fees and disbursements of such counsel shall be at the expense of such
indemnified party unless (i) the indemnifying party shall have failed to retain
counsel for the indemnified person as aforesaid or (ii) the indemnifying party
and such indemnified party shall have mutually agreed to the retention of such
counsel. It is understood that the indemnifying party shall not, in connection
with any action or related actions in the same jurisdiction, be liable for the
fees and disbursements of more than one firm (together with local counsel) to
act as counsel for the indemnified party. The indemnifying party shall not be
liable for any settlement of any proceeding effected without its written consent
(which shall not be unreasonably withheld or delayed), but if settled with such
consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party from and against any loss or
liability by reason of such settlement or judgment. No indemnifying party shall,
without the written consent of the indemnified party (which shall not be
unreasonably withheld or delayed), effect the settlement or compromise of, or
consent to the entry of any judgment with respect to, any pending or threatened
action in respect of which indemnification may be sought hereunder (whether or
not the indemnified party is an actual or potential party to such action) unless
such settlement, compromise or judgment (i) includes an unconditional release of
such indemnified party from all liability arising out of such action and (ii)
does not include a statement as to or an admission of fault, culpability or a
failure to act by or on behalf of such indemnified party.

          If for any reason the indemnification provided for in the first two
paragraphs of this Section 5 is unavailable or insufficient to hold harmless an
indemnified party under such paragraphs in respect of any Claims or expenses in
respect thereof referred to therein, then each indemnifying party shall in lieu
of indemnifying such indemnified party contribute to the amount paid or payable
by such indemnified party as a result of such Claims or expenses in such
proportion as appropriate to reflect the relative fault of the Company, on the
one hand, and the underwriters and the sellers of such Debentures, on the other,
in connection with the statements

                                       8

<PAGE>


or omissions which resulted in such Claims or expenses as well as any other
relevant equitable considerations, including the failure to give any notice
under the third paragraph of this Section 5. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact relates to information supplied by the
indemnifying party, on the one hand, or the indemnified party, on the other, and
to the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
each of you agree that it would not be just and equitable if contributions
pursuant to this paragraph were determined by PRO RATA allocation (even if all
of the sellers of such Debentures were treated as one entity for such purpose)
or by any other method of allocation which did not take account of the equitable
considerations referred to above in this paragraph. The amount paid or payable
by an indemnified party as a result of the Claims and expenses in respect
thereof, referred to above in this paragraph, shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this paragraph, no seller of such Debentures
or related indemnified party shall be required to contribute any amount in
excess of the amount of proceeds (net of underwriting discounts and commissions)
received by such seller from the sale of Debentures covered by such registration
statement. No person guilty of fraudulent misrepresentations (within the meaning
of Section 11(f) of the Securities Act), shall be entitled to contribution from
any person who is not guilty of such fraudulent misrepresentation.

          The indemnification of underwriters provided for in this Section 5
shall be on such other terms and conditions as are at the time customary and
reasonably required by such underwriters. In that event the indemnification of
the sellers of Debentures in such underwriting shall at the sellers' request be
modified to conform to such terms and conditions.

          The indemnification and contribution agreements contained herein shall
be in addition to any other rights to indemnification and contribution which any
indemnified party may have pursuant to law or contract or otherwise, shall
remain operative and in full force and effect regardless of any investigation
made or omitted by or on behalf of any indemnified party and shall survive the
transfer of Debentures by any such party.

          6. MISCELLANEOUS.

          (a) This Agreement shall inure to the benefit of an be binding upon
     the successors and assigns of each of the parties, including without
     limitation and without the need for an express assignment, subsequent

     permit any assignment, transfer or other disposition of Transfer Restricted
     Securities in violation of the terms hereof or of the Purchase Agreement or
     the Indenture. If any transferee of any holder of Debentures shall acquire
     Transfer Restricted Securities in any manner, whether by operation of law
     or otherwise, such Transfer Restricted Securities shall be held subject to
     all of the terms of this Agreement, and by taking and holding such Transfer
     Restricted Securities such Person shall be conclusively

                                       9

     such Person shall be entitled to received the benefits hereof.

          (b) Any notice or other communications required or permitted hereunder
     shall be deemed to be sufficient and received if contained in a written
     instrument delivered in person or by courier or duly sent by first class
     certified mail, postage prepaid, or by facsimile addressed to such party at
     the address or facsimile number set forth below:

     WITH THE LAWS OF THE STATE OF NEW YORK.

          (d) This Agreement constitutes the entire agreement of the parties
     with respect to the subject matter hereof and may not be modified or
     amended except by an instrument in writing signed by the Company and (i)
     the holders of a majority of the principal amount of maturity of the
     Debentures and (ii) if adversely affected thereby, each of the other

     enforcement of such waiver is sought.

          (f) Headings and section reference numbers in this Agreement are for
     reference purposes only and shall not in any way affect the meaning or
     interpretation of this Agreement.

          (g) In the event that any one or more of the provisions set forth

     unenforceability shall not affect any other provision of this Agreement.

          (h) Except for holders of the Debentures and as specifically set forth
     in Section 5 hereof, this Agreement is not intended to confer any rights or
     remedies upon any person other than the parties hereto.

          (i) Each party hereto agrees that a remedy at law for any breach or
     threatened breach by such party of this Agreement would be inadequate and

     performance of this Agreement in addition to any other available rights and
     remedies in case of any such breach or threatened breach.

          (j) EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL
     RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO

Agreement as a sealed instrument, all as of the day and year first above
written.

Ladies and Gentlemen:

                  Concentra Operating Corporation, a Nevada corporation (the
"COMPANY") and a wholly owned subsidiary of Concentra Managed Care, Inc.
("HOLDINGS"), proposes to issue and sell to Donaldson, Lufkin & Jenrette
Securities Corporation ("DLJ"), Chase Securities Inc., Credit Suisse First
Boston Corporation, Deutsche Bank Securities Inc. and Fleet Securities, Inc.
(each an "INITIAL PURCHASER" and, together, the "INITIAL PURCHASERS") an
aggregate of $190,000,000 in principal amount of its 13% Series A Senior
Subordinated Notes due 2009 (the "SERIES A NOTES"), subject to the terms and
conditions set forth herein. The Series A Notes are to be issued pursuant to the
provisions of an indenture (the "INDENTURE"), to be dated as of the Closing Date
(as defined below), between the Company, the Subsidiary Guarantors named therein
and United States Trust Company of New York, as trustee (the "Trustee"). The
Series A Notes and the Series B Notes (as defined below) issuable in exchange
therefor are collectively referred to herein as the "NOTES." The Notes

                                      -2-

<PAGE>


will be guaranteed (the "SUBSIDIARY GUARANTEES") by all existing and future
subsidiaries of the Company (the "SUBSIDIARY GUARANTORS") except Permitted Joint
Ventures, as further provided in the Indenture. Capitalized terms used but not
defined herein shall have the meanings given to such terms in the Offering
Memorandum (as defined herein).

                  1. OFFERING MEMORANDUM. The Series A Notes will be offered and
sold to the Initial Purchasers pursuant to one or more exemptions from the
registration requirements under the Securities Act of 1933, as amended (the
"ACT"). The Company and the Subsidiary Guarantors have prepared a preliminary
offering memorandum, dated July 23, 1999 (the "PRELIMINARY OFFERING
MEMORANDUM"), and a final offering memorandum, dated August 5, 1999 (the
"OFFERING MEMORANDUM"), each relating to the Series A Notes and the Subsidiary
Guarantees.

                  Upon original issuance thereof, and until such time as the
same is no longer required pursuant to the Indenture, the Series A Notes (and
all securities (other than the Series B Notes) issued in exchange therefor or in
substitution thereof) shall bear the following legend:

                  "THIS NOTE (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER
THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED WITHIN
THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS, EXCEPT
AS SET FORTH IN THE NEXT SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL
INTEREST HEREIN, THE HOLDER:

         (1)      REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER"
                  (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) (A "QIB"),
                  OR (B) IT HAS ACQUIRED THIS NOTE IN AN OFFSHORE TRANSACTION IN
                  COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT,

         (2)      AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS NOTE
                  EXCEPT (A) TO THE COMPANY OR ANY OF ITS SUBSIDIARIES, (B) TO A
                  PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QIB PURCHASING
                  FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QIB IN A
                  TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (C) IN AN
                  OFFSHORE TRANSACTION MEETING THE REQUIREMENTS OF

                                      -3-

<PAGE>


                  RULE 903 OR 904 OF THE SECURITIES ACT, (D) IN A TRANSACTION
                  MEETING THE REQUIREMENTS OF RULE 144 UNDER THE SECURITIES ACT,
                  (E) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION
                  REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION
                  OF COUNSEL ACCEPTABLE TO THE COMPANY) OR (F) PURSUANT TO AN
                  EFFECTIVE REGISTRATION STATEMENT AND, IN EACH CASE, IN
                  ACCORDANCE WITH THE APPLICABLE SECURITIES LAWS OF ANY STATE OF
                  THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION, AND

         (3)      AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE
                  OR AN INTEREST HEREIN IS TRANSFERRED A NOTICE SUBSTANTIALLY TO
                  THE EFFECT OF THIS LEGEND.

                  AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION" AND "UNITED
                  STATES" HAVE THE MEANINGS GIVEN TO THEM BY RULE 902 OF
                  REGULATION S UNDER THE SECURITIES ACT. THE INDENTURE CONTAINS
                  A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY
                  TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING."

                  2. AGREEMENTS TO SELL AND PURCHASE. On the basis of the
representations, warranties and covenants contained in this Agreement, and
subject to the terms and conditions contained herein, the Company agrees to
issue and sell to the Initial Purchasers, and each Initial Purchaser severally
agrees to purchase from the Company, the principal amount of Series A Notes set
forth opposite the name of such Initial Purchaser on Schedule A hereto at a
purchase price equal to 97.25% of the principal amount thereof (the "PURCHASE
PRICE").

                  3. TERMS OF OFFERING. The Initial Purchasers have advised the
Company that the Initial Purchasers will make offers (the "EXEMPT RESALES") of
the Series A Notes purchased hereunder on the terms set forth in the Offering
Memorandum, as amended or supplemented, solely to (i) persons whom the Initial
Purchasers reasonably believe to be "qualified institutional buyers" as defined
in Rule 144A under the Act ("QIBS") and (ii) to persons permitted to purchase
the Series A Notes in offshore transactions in reliance upon Regulation S under
the Act (each, a "REGULATION S PURCHASER") (such persons specified in clauses
(i) and (ii) being referred to herein as the "ELIGIBLE PURCHASERS"). The Initial
Purchasers will offer the Series A Notes to Eligible Purchasers initially at the
offering

                                      -4-

<PAGE>


price set forth on the cover of the Offering Memorandum. Such price may be
changed at any time without notice.

                  Holders (including subsequent transferees of the Series A
Notes) will have the registration rights set forth in the registration rights
agreement (the "REGISTRATION RIGHTS AGREEMENT"), to be dated the Closing Date,
substantially as described in the Offering Memorandum and containing other
customary and reasonable provisions. Pursuant to the Registration Rights
Agreement, the Company will agree to file with the Securities and Exchange
Commission (the "COMMISSION"), under the circumstances set forth therein, (i) a
registration statement under the Act (the "EXCHANGE OFFER REGISTRATION
STATEMENT") relating to the Company's 13% Series B Senior Subordinated Notes due
2009 (the "SERIES B NOTES"), to be offered in exchange for the Series A Notes
(such offer to exchange being referred to as the "EXCHANGE OFFER") and/or (ii) a
shelf registration statement pursuant to Rule 415 under the Act (the "SHELF
REGISTRATION STATEMENT" and, together with the Exchange Offer Registration
Statement, the "REGISTRATION STATEMENTS") relating to the resale by certain
holders of the Series A Notes and use its reasonable best efforts to cause such
Registration Statements to be declared and remain effective and usable for the
periods specified in the Registration Rights Agreement and to consummate the
Exchange Offer. This Agreement, the Indenture, the Notes, the Subsidiary
Guarantees, the Registration Rights Agreement, the Contribution Agreement, the
Merger Agreement and the Senior Credit Facilities (each as defined in the
Offering Memorandum) are hereinafter sometimes referred to collectively as the
"OPERATIVE DOCUMENTS."

                  4. DELIVERY AND PAYMENT.

                     (a) Delivery of, and payment of the Purchase Price for, the
Series A Notes shall be made at the offices of Reboul, MacMurray, Hewitt,
Maynard & Kristol or such locations as may be mutually acceptable to the parties
hereto. Such delivery and payment shall be made at 9:00 a.m., New York City
time, on the eighth business day following the date of this Agreement (August
17, 1999) or at such other time as shall be agreed upon by the Initial
Purchasers and the Company. The time and date of such delivery and the payment
are herein called the "CLOSING DATE."

                     (b) One or more of the Series A Notes in the definitive
global form, registered in the name of Cede & Co., as nominee of the Depository
Trust Company ("DTC"), having an aggregate principal amount corresponding to the
aggregate principal amount of the Series A Notes (collectively, the "GLOBAL
NOTE"), shall be delivered by the Company to the Initial Purchasers (or as the
Initial Purchasers direct), in each case with any transfer taxes thereon duly
paid by the Company against payment by the Initial

                                      -5-

                  5. AGREEMENTS OF THE COMPANY. The Company hereby agrees with
each Initial Purchaser as follows:

                     (a) To advise the Initial Purchasers promptly and, if
requested by an Initial Purchaser, confirm such advice in writing, (i) of the
issuance by any state securities commission of any stop order suspending the
qualification or exemption from qualification of any Series A Notes for offering
or sale in any jurisdiction designated by an Initial Purchaser pursuant to
Section 5(e) hereof, or the initiation of any proceeding by any state securities
commission or any other federal or state regulatory authority for such purpose
and (ii) of the happening of any event during the period referred to in Section
5(c) below that makes any statement of a material fact made in the Offering
Memorandum, as then amended or supplemented, untrue or that requires any
additions to or changes in the Offering Memorandum, as then amended or
supplemented, in order to make the statements therein, in light of the
circumstances under which they are made, not misleading. The Company shall use
its reasonable best efforts to prevent the issuance of any stop order or order
suspending the qualification or exemption of any Series A Notes under any state
securities or Blue Sky laws and, if at any time any state securities commission
or other federal or state regulatory authority shall issue an order suspending
the qualification or exemption of any Series A Notes under any state securities
or Blue Sky laws, the Company shall use its reasonable best efforts to obtain
the withdrawal or lifting of such order at the earliest possible time.

                     (b) To furnish the Initial Purchasers and those persons
identified by the Initial Purchasers to the Company, without charge, as many
copies of the Offering Memorandum, and any amendments or supplements thereto, as
the Initial Purchasers may reasonably request. Subject to the Initial
Purchasers' compliance with their representations and warranties and agreements
set forth in Section 7 hereof, the Company consents to the use of the
Preliminary Offering Memorandum (prior to the availability of the Offering
Memorandum) and the Offering Memorandum, and any amendments and supplements
thereto, by the Initial Purchasers in connection with Exempt Resales.

                     (c) During such period as in the opinion of counsel for the
Initial Purchasers an Offering Memorandum is required by law to be delivered in
connection with Exempt Resales by the Initial Purchasers and in connection with
market-making activities of the Initial Purchasers prior to the consummation of
the Exchange Offer (i) not

                                      -6-

<PAGE>


to make any amendment or supplement to the Offering Memorandum of which the
Initial Purchasers shall not previously have been advised or to which the
Initial Purchasers shall reasonably object within a reasonable time after being
so advised and (ii) to prepare promptly upon the Initial Purchasers' reasonable
request, any amendment or supplement to the Offering Memorandum which may be
necessary or advisable in connection with Exempt Resales or such market-making
activities.

                     (d) If, during the period referred to in Section 5(c)
above, any event shall occur as a result of which it becomes necessary to amend
or supplement the Offering Memorandum in order to make the statements therein,
in the light of the circumstances as of the date the Offering Memorandum is
delivered to an Eligible Purchaser, not misleading, or if it is necessary to
amend or supplement the Offering Memorandum to comply with any applicable law,
promptly to prepare an appropriate amendment or supplement to such Offering
Memorandum so that the statements therein, as so amended or supplemented, will
not, in the light of the circumstances when it is so delivered, be misleading,
or so that such Offering Memorandum, as so amended or supplemented, will comply
with applicable law, and to furnish to the Initial Purchasers and such other
persons as the Initial Purchasers may designate such number of copies thereof as
the Initial Purchasers may reasonably request.

                     (e) Prior to the sale of all the Series A Notes pursuant to
Exempt Resales as contemplated hereby, to cooperate with the Initial Purchasers

jurisdictions as the Initial Purchasers may reasonably request and to continue
such qualification in effect so long as required to consummate such Exempt
Resales and to file such consents to service of process or other documents as
may be necessary in order to effect such registration or qualification;
PROVIDED, HOWEVER, that neither the Company nor any Subsidiary Guarantor shall
be required in connection therewith to register or qualify as a foreign
corporation in any jurisdiction in which it is not now so qualified or to take
any action that would subject it to service of process or taxation other than as
to matters and transactions relating to Exempt Resales, in any jurisdiction in
which it is not now so subject.

                     (f) So long as the Notes are outstanding, for a period of
two (2) years after the Closing Date and thereafter so long as an Initial
Purchaser is making a market in the Notes, to furnish to the Initial Purchasers

Initial Purchaser (it being understood that all representations and warranties
herein with respect to the condition, financial or otherwise, or the earnings,
business, management or operations of the Company give effect to the
Transactions as if they had occurred as of the date hereof) that:

                     (a) The Preliminary Offering Memorandum as of its date did
not and the Offering Memorandum as of the date hereof does not, and as of the
Closing Date the Offering Memorandum, as supplemented or amended, will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading,
except that the representations and warranties contained in this paragraph (a)
shall not apply to statements in or omissions from the Preliminary Offering

be deemed to have provided any other information (and therefore are not

agreement with respect to any party other than the Initial Purchasers. No
contract or document that would be required to be described in the Offering
Memorandum if the Offering Memorandum were a prospectus contained in a
registration statement on Form S-1 filed under the Act is not so described. The
agreements listed on SCHEDULE C hereto represent all of the material agreements
of the Company that would be required to be filed as exhibits if the Offering

preventing the use of the Preliminary Offering Memorandum or the Offering

the Company and the Subsidiary Guarantors is duly qualified and is in good
standing as a foreign corporation authorized to do business in each jurisdiction
in which such qualification is required, except where the failure to be so
qualified or in good standing would not (i) have a material adverse effect on
the business, prospects, financial condition or results of operations of the
Company and the Subsidiary Guarantors, taken as a whole, (ii) materially
interfere with or materially adversely affect the issuance or marketability of
the Series A Notes pursuant hereto or (iii) materially adversely affect in any

                     (d) This Agreement has been duly authorized, executed and
delivered by the Company and the Subsidiary Guarantors and, assuming the due

Company, Holdings, each Permitted Joint Venture and each Subsidiary Guarantor is
in compliance with all the terms and conditions of its permits and with the
rules and regulations of the authorities and governing bodies having

notice or elapse of time or both, would allow revocation, suspension or
termination of any such permit, or results or, after notice or lapse of time or
both, would result in any other impairment of the rights of the holder of any
such permit; and such permits contain no restrictions that are unduly burdensome
to the Company, Holdings, such Permitted Joint Venture or such Subsidiary
Guarantor, except, in each case, where such failure to be valid and in full
force and effect or to be in compliance, the occurrence of any such event or the
presence of any such restriction would not, singly or in the aggregate, have a
Material Adverse Effect.

                     (u) Except as would not, singly or in the aggregate, have

knowledge after due inquiry, the use of the Intellectual Property in connection
with the

                                      -19-

business and operations of the Company, Holdings, each Permitted Joint Venture

nor any of the Subsidiary Guarantors (i) has received notice from any insurer or
agent of such insurer that substantial capital improvements or other material
expenditures will have to be made in order to continue such insurance or (ii)
has any reason to believe that it will not be able to renew its existing

relationship, direct or indirect, exists between or among the Company, Holdings,
any of the Permitted Joint Ventures or any of the Subsidiary Guarantors on the
one hand and the directors, officers, stockholders, customers or suppliers of
the Company, Holdings, any of the Permitted Joint Ventures or any of the
Subsidiary Guarantors on the other hand, which would be required by the Act to

opinion of counsel acceptable to the Company) or (VI) pursuant to an effective
registration statement and, in each case, in accordance with the applicable
securities laws of any state of the United States or any other applicable
jurisdiction and (y) they will deliver to each person to whom such Series A
Notes or an interest therein is transferred a notice substantially to the effect
of the foregoing.

                     (e) Such Initial Purchaser and its affiliates or any person
acting on its or their behalf have not engaged or will not engage in any
directed selling efforts within the meaning of Regulation S with respect to the
Series A Notes or the Subsidiary Guarantees.

                     (f) The Series A Notes offered and sold by such Initial
Purchaser pursuant hereto in reliance on Regulation S have been and will be
offered and sold only in offshore transactions.

                     (g) The sale of the Series A Notes offered and sold by such
Initial Purchaser pursuant hereto in reliance on Regulation S is not part of a
plan or scheme to evade the registration provisions of the Act.

                     (h) Such Initial Purchaser agrees that it has not offered
or sold and will not offer or sell the Series A Notes in the United States or
to, or for the benefit or account of, a U.S. Person (other than a distributor),
in each case, as defined in Rule 902 under the Act (i) as part of its
distribution at any time and (ii) otherwise until 40 days after the later of the
commencement of the offering of the Series A Notes pursuant hereto and the
Closing Date, other than in accordance with Regulation S of the Act or another
exemption from the registration requirements of the Act. Such Initial Purchaser
agrees that, during such 40-day restricted period, it will not cause any
advertisement with respect to the Series A Notes (including any "tombstone"
advertisement) to be published in any newspaper or periodical or posted in any
public place and will not issue any circular relating to the Series A Notes,
except such advertisements as are permitted by and include the statements
required by Regulation S.

                     (i) Such Initial Purchaser agrees that, at or prior to
confirmation of a sale of Series A Notes by it to any distributor, dealer or
person receiving a selling concession, fee or other remuneration during the
40-day restricted period referred to in Rule 903(b)(3) under the Act, it will
send to such distributor, dealer or person receiving a selling concession, fee
or other remuneration a confirmation or notice to substantially the following
effect:

         "The Series A Notes covered hereby have not been registered under the
         U.S. Securities Act of 1933, as amended (the "Securities Act"), and may
         not be offered and sold within the United States or to, or for the
         account or benefit of, U.S. persons (i) as part of your distribution at
         any time or (ii) otherwise until 40 days after the later of the
         commencement of the Offering and the Closing Date, except in either
         case in accordance with Regulation S under the Securities Act (or Rule
         144A or to Accredited Institutions in transactions that are exempt from
         the registration requirements of the Securities Act). Terms used above
         have the meanings assigned to them in Regulation S."

              The Initial Purchasers acknowledge that the Company and, for
purposes of the opinions to be delivered to each Initial Purchaser pursuant to
Section 9 hereof, counsel to the Company and counsel to the Initial Purchasers
will rely upon the accuracy and truth of the foregoing representations and the
Initial Purchasers hereby consent to such reliance.

                  8. INDEMNIFICATION.

                     (a) The Company and each Subsidiary Guarantor agree,
jointly and severally, to indemnify and hold harmless the Initial Purchasers,
its directors, its officers and each person, if any, who controls an Initial
Purchaser within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, from and against any and all losses, claims, damages, liabilities
and judgments (including, without limitation, any legal or other expenses
incurred in connection with investigating or defending any matter, including any
action, that could give rise to any such losses, claims, damages, liabilities or
judgments) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Offering Memorandum (or any amendment or
supplement thereto), the Preliminary Offering Memorandum or any Rule 144A
Information provided by the Company, Holdings or any Subsidiary Guarantor to any
holder or prospective purchaser of Series A Notes pursuant to Section 5(h) or
caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as such losses, claims, damages, liabilities or
judgments are caused by any such untrue statement or omission or alleged untrue
statement or omission based upon information relating to an Initial Purchaser
furnished in writing to the Company by such Initial Purchaser; and PROVIDED,
FURTHER, that the Company and each Subsidiary Guarantor shall not be liable to
any Initial Purchaser under the indemnity agreement in this subsection (a) with
respect to any Preliminary Offering Memorandum to the extent that any such loss,
claim, damage or liability of such Initial Purchaser results from the fact that
such Initial Purchaser sold Series A Notes to a person as to whom it shall be
established that there was not sent or given, at or prior to the written
confirmation of such sale, a copy of the Offering Memorandum or of the Offering
Memorandum as then amended or supplemented in any case where such delivery is
required by the Act if the Company or any Subsidiary Guarantor has previously
furnished copies thereof in sufficient quantity to such Initial Purchaser and
the loss, claim, damage or liability of such Initial Purchaser results from an
untrue statement or omission of a material fact contained in the Preliminary
Offering Memorandum which was identified in writing at such time to such Initial
Purchaser and corrected in the Offering Memorandum.

                     (b) Each Initial Purchaser severally and not jointly agrees
to indemnify and hold harmless the Company and the Subsidiary Guarantors, and
their respective directors and officers and each person, if any, who controls
(within the meaning of Section 15 of the Act or Section 20 of the Exchange Act)
the Company or the Subsidiary Guarantors, to the same extent as the foregoing
indemnity from the Company and the Subsidiary Guarantors to the Initial
Purchasers but only with reference to information

                                      -29-

<PAGE>


relating to such Initial Purchaser furnished in writing to the Company by such
Initial Purchaser expressly for use in the Preliminary Offering Memorandum or
the Offering Memorandum (or any supplement or amendment thereto).

                     (c) In case any action shall be commenced involving any
person in respect of which indemnity may be sought pursuant to Section 8(a) or
8(b) (the "INDEMNIFIED PARTY"), the indemnified party shall promptly notify the
person against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in
writing and the indemnifying party shall assume the defense of such action,
including the employment of counsel reasonably satisfactory to the indemnified
party and the payment of all fees and expenses of such counsel, as incurred
(except that in the case of any action in respect of which indemnity may be
sought pursuant to both Sections 8(a) and 8(b), an Initial Purchaser shall not
be required to assume the defense of such action pursuant to this Section 8(c),
but may employ separate counsel and participate in the defense thereof, but the
fees and expenses of such counsel, except as provided below, shall be at the
expense of such Initial Purchaser). Any indemnified party shall have the right
to employ separate counsel in any such action and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
the indemnified party unless (i) the employment of such counsel shall have been
specifically authorized in writing by the indemnifying party, (ii) the
indemnifying party shall have failed to assume the defense of such action or
employ counsel reasonably satisfactory to the indemnified party or (iii) the
named parties to any such action (including any impleaded parties) include both
the indemnified party and the indemnifying party, and the indemnified party
shall have been advised by such counsel that there may be one or more legal
defenses available to it which are different from or additional to those
available to the indemnifying party (in which case the indemnifying party shall
not have the right to assume the defense of such action on behalf of the
indemnified party). In any such case, the indemnifying party shall not, in
connection with any one action or separate but substantially similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the fees and expenses of more than one separate
firm of attorneys (in addition to any local counsel) for all indemnified parties
and all such fees and expenses shall be reimbursed as they are incurred. Such
firm shall be designated in writing by DLJ, in the case of the parties
indemnified pursuant to Section 8(a), and by the Company, in the case of parties
indemnified pursuant to Section 8(b). The indemnifying party shall indemnify and
hold harmless the indemnified party from and against any and all losses, claims,
damages, liabilities and judgments by reason of any settlement of any action (i)
effected with its written consent or (ii) effected without its written consent
if the settlement is entered into more than twenty business days after the
indemnifying party shall have received a request from the indemnified party for
reimbursement for the fees and expenses

                                      -30-

<PAGE>


of counsel (in any case where such fees and expenses are at the expense of the
indemnifying party) and, prior to the date of such settlement, the indemnifying
party shall have failed to comply with such reimbursement request. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement or compromise of, or consent to the entry of
judgment with respect to, any pending or threatened action in respect of which
the indemnified party is or could have been a party and indemnity or
contribution may be or could have been sought hereunder by the indemnified
party, unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability on claims that
are or could have been the subject matter of such action and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of the indemnified party.

                     (d) To the extent the indemnification provided for in this
Section 8 is unavailable to an indemnified party or insufficient in respect of
any losses, claims, damages, liabilities or judgments referred to therein, then
each indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company and the Subsidiary Guarantors, on the one hand, and the Initial
Purchaser, on the other hand, from the offering of the Series A Notes or (ii) if
the allocation provided by clause 8(d)(i) above is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause 8(d)(i) above but also the relative fault of the
Company and the Subsidiary Guarantors, on the one hand, and any Initial
Purchaser, on the other hand, in connection with the statements or omissions
which resulted in such losses, claims, damages, liabilities or judgments, as
well as any other relevant equitable considerations. The relative benefits
received by the Company and the Subsidiary Guarantors, on the one hand, and any
Initial Purchaser, on the other hand, shall be deemed to be in the same
proportion as the total net proceeds from the offering of the Series A Notes
(after underwriting discounts and commissions, but before deducting expenses)
received by the Company, and the total discounts and commissions received by the
Initial Purchasers bear to the total price to investors of the Series A Notes.
The relative fault of the Company and the Subsidiary Guarantors, on the one
hand, and any of the Initial Purchasers, on the other hand, shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to the information supplied by the Company or the
Subsidiary Guarantors, on the one hand, or an Initial Purchaser, on the other
hand, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

                                      -31-

<PAGE>


                  The Company and the Subsidiary Guarantors, and the Initial
Purchasers agree that it would not be just and equitable if contribution
pursuant to this Section 8(d) were determined by pro rata allocation (even if
the Initial Purchasers were treated as one entity for such purpose) or by any
other method of allocation which does not take account of the equitable
considerations referred to in the immediately preceding paragraph. The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages, liabilities or judgments referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses incurred by such indemnified party in
connection with investigating or defending any matter, including any action,
that could have given rise to such losses, claims, damages, liabilities or
judgments. Notwithstanding the provisions of this Section 8, no Initial
Purchaser shall be required to contribute any amount in excess of the amount by
which the total discounts and commissions received by such Initial Purchaser
exceeds the amount of any damages which such Initial Purchaser has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Initial Purchasers' obligations to contribute pursuant to
this Section 8(d) are several in proportion to the respective principal amounts
of Series A Notes purchased by each of the Initial Purchasers hereunder, and not
joint.

                  9. CONDITIONS OF INITIAL PURCHASERS' OBLIGATIONS. The
obligations of the Initial Purchasers to purchase the Series A Notes under this
Agreement are subject to the satisfaction of each of the following conditions:

                     (a) All the representations and warranties of the Company
and the Subsidiary Guarantors contained in this Agreement shall be true and
correct on the date hereof and on the Closing Date with the same force and
effect as if made on and as of the Closing Date.

                     (b) On or after the date hereof, (i) there shall not have
occurred any downgrading, suspension or withdrawal of, nor shall any notice have
been given of any potential or intended downgrading, suspension or withdrawal
of, or of any review (or any potential or intended review) for a possible change
that does not indicate the direction of the possible change in, any rating of
the Company, Holdings or the Subsidiary Guarantors or any securities of the
Company, Holdings or the Subsidiary Guarantors (including, without limitation,
the placing of any of the foregoing ratings on credit watch with negative or
developing implications or under review with an uncertain direction) by any
"nationally recognized statistical rating organization," as such term is defined
for purposes

                                      -32-

<PAGE>


of Rule 436(g)(2) under the Act, (ii) there shall not have occurred any change,
nor shall any notice have been given of any potential or intended change, in the
outlook for any rating of the Company, Holdings or the Subsidiary Guarantors or
any securities of the Company, Holdings or the Subsidiary Guarantors by any such
rating organization and (iii) no such rating organization shall have given
notice that it has assigned (or is considering assigning) a lower rating to the
Notes than that on which the Notes were marketed.

                     (c) The Initial Purchasers shall have received on the
Closing Date a certificate dated the Closing Date, signed by the President and
the Chief Financial Officer of the Company and each of the Subsidiary
Guarantors, confirming, as of the Closing Date, the matters set forth in
paragraphs (a), (b), (e), (q), (r) and (s) (the first clause of which may be
limited to the Company's knowledge) of this Section 9 and, Section 6(dd) and
stating that each of the Company and the Subsidiary Guarantors has complied in
all material respects with all the agreements and conditions herein contained
and required to be complied with and satisfied on or prior to the Closing Date.

                     (d) Since the respective dates as of which information is
given in the Offering Memorandum, other than as set forth in the Offering
Memorandum (including, without limitation, the Transaction and exclusive of any
amendments or supplements thereto subsequent to the date of this Agreement), (i)
there shall not have occurred any change or any development involving a
prospective change in the condition, financial or otherwise, or the earnings,
business, prospects, management or operations of the Company and the Subsidiary
Guarantors, (ii) there shall not have been any change or any development
involving a prospective change in the capital stock or increase in the long-term
debt of the Company or any of the Subsidiary Guarantors and (iii) neither the
Company nor any of the Subsidiary Guarantors shall not have incurred any
material liability or obligation, direct or contingent, the effect of which, in
any such case described in clause 9(d)(i), 9(d)(ii) or 9(d)(iii), in your good
faith judgment, is material and adverse and, in your good faith judgment, makes
it impracticable to market the Series A Notes on the terms and in the manner
contemplated in the Offering Memorandum.

                     (e) No action shall have been taken and no statute, rule,
regulation or order shall have been enacted, adopted or issued by any
governmental agency which would, as of the Closing Date, prevent the issuance or
sale of any of the Notes, prevent the consummation of the Transactions or
otherwise have a Material Adverse Effect; no action, suit or proceeding shall be
pending against or, to the knowledge of the Company and Holdings, threatened
against, the Company, Holdings, any of the Permitted Joint Ventures or any of
the Subsidiary Guarantors before any court or arbitrator or any governmental
body, agency or official which would reasonably be expected to prohibit,
interfere with or

                                      -33-

<PAGE>


adversely affect the issuance or sale of the Notes, the consummation of the
Transactions or otherwise have a Material Adverse Effect; and no stop order,
injunction, restraining order, or order of any nature preventing the use of the
Offering Memorandum, or any amendment or supplement thereto, or any order
asserting that any of the transactions contemplated by this Agreement are
subject to the registration requirements of the Act shall have been issued.

                     (f) On the Closing Date, the Initial Purchasers shall have
received an opinion, dated the Closing Date, of Schreck Morris, special Nevada

                     (4) Each of the Subsidiary Guarantors organized under the
                laws of the state of Nevada (the "NEVADA GUARANTORS") is a

                  (g) On the Closing Date, the Initial Purchasers shall have
received an opinion, dated the Closing Date, of Richard A. Parr II, general
counsel for the Company, Holdings and the Subsidiary Guarantors, substantially
to the effect that:

                     (1) Each of the Subsidiary Guarantors (other than those
                organized under the laws of the State of Nevada and
                Massachusetts) (the "RELEVANT GUARANTORS") has been duly
                organized, is validly existing as a corporation in good standing

                the requisite corporate power and authority to authorize the

                and perform its obligations under each Operative Document to
                which it is a party.

                     (2) Each of the Company, Holdings and the Subsidiary
                Guarantors is duly qualified and is in good standing as a
                foreign corporation authorized to do business in each
                jurisdiction in which such qualification is required, except
                where the failure to be so qualified or in good standing would
                not be reasonably expected to have a Material Adverse Effect.

                     (3) All of the outstanding capital stock of Holdings and
                each Relevant Guarantor (i) has been duly authorized and validly
                issued and (ii) is fully paid, nonassessable and, to such
                counsel's knowledge after due inquiry and other than under the

shall become effective upon the delivery of this Agreement by the parties
hereto.

              This Agreement may be terminated at any time on or prior to the

of the following has occurred: (i) any outbreak or escalation of hostilities or
other national or international calamity or crisis or change in economic
conditions or in the financial markets of the United States or elsewhere that,

declaration of a banking moratorium by either federal or New York State

refuse to purchase the Series A Notes which it has agreed to purchase hereunder
on such date and the aggregate principal amount of the Series A Notes which such
defaulting Initial Purchaser agreed but failed or

                                      -46-

<PAGE>


refused to purchase is not more than one-tenth of the aggregate principal amount
of the Series A Notes to be purchased on such date by all Initial Purchasers,
each non-defaulting Initial Purchaser shall be obligated to purchase the Series
A Notes which such defaulting Initial Purchaser or Initial Purchasers, as the
case may be, agreed but failed or refused to purchase on such date; PROVIDED
that in no event shall the aggregate principal amount of the Series A Notes
which any Initial Purchaser has agreed to purchase pursuant to Section 2 hereof
be increased pursuant to this Section 10 by an amount in excess of one-ninth of
such principal amount of the Series A Notes without the written consent of such
Initial Purchaser. If on the Closing Date any Initial Purchaser or Initial
Purchasers shall fail or refuse to purchase Series A Notes and the aggregate
principal amount of the Series A Notes with respect to which such default occurs
is more than one-tenth of the aggregate principal amount of the Series A Notes
to be purchased by all Initial Purchasers and arrangements satisfactory to the
Initial Purchasers and the Company for purchase of such Series A Notes are not
made within 48 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting Initial Purchaser and the Company
and the Subsidiary Guarantors. In any such case which does not result in
termination of this Agreement, either you or the Company shall have the right to
postpone the Closing Date, but in no event for longer than seven days, in order
that the required changes, if any, to the Offering Memorandum or any other
documents or arrangements may be effected. Any action taken under this paragraph
shall not relieve any defaulting Initial Purchaser from liability in respect of
any default of any such Initial Purchaser under this Agreement. Any notice of
termination pursuant to this Section 10 shall be by telephone, telex, facsimile
or telegraph, confirmed in writing by letter sent within three days thereof.

                  11. MISCELLANEOUS. Notices given pursuant to any provision of

the Subsidiary Guarantors and the Initial Purchasers set forth in or made

              If for any reason the Series A Notes are not delivered by or on
behalf of the Company as provided herein (other than as a result of any
termination of this Agreement pursuant to Section 10), the Company and each
Subsidiary Guarantor, jointly and severally, agrees to reimburse the Initial
Purchasers for all out-of-pocket expenses (including the fees and disbursements
of counsel) reasonably incurred by them. Notwithstanding any termination of this
Agreement, the Company and each Subsidiary Guarantor, jointly and severally,
shall be liable for all expenses which it has agreed to pay pursuant to Section
5(h) hereof. The Company and each Subsidiary Guarantor also agrees to reimburse
the Initial Purchasers, their respective directors and officers and any person
controlling an Initial Purchaser for any and all fees and expenses (including,
without limitation, the fees and disbursements of counsel) reasonably incurred
by them in connection with enforcing their rights under this Agreement.

              Except as otherwise provided, this Agreement has been and is made
solely for the benefit of and shall be binding upon the parties hereto and their
respective successors and the officers and directors and other persons referred
to in Section 8, all as and to the extent provided in this Agreement, and no
other person shall acquire or have any right under or by virtue of this
Agreement. The term "successors and assigns" shall not include a purchaser of
any of the Series A Notes from the Initial Purchasers merely because of such
purchase.

              This Agreement shall be governed and construed in accordance with
the laws of the State of New York.

              This Agreement may be signed in various counterparts which
together shall constitute one and the same instrument.

outstanding which, when added to such Lender's Revolving Percentage of the L/C
Obligations then outstanding, does not exceed the amount of such Lender's

whole or in part, and reborrowing, all in accordance with the terms and
conditions hereof. The Revolving Loans may from time to time be Eurodollar Loans

borrow under the Revolving Commitments during the Revolving Commitment Period on
any Business Day, PROVIDED that the Borrower shall give the Administrative Agent
irrevocable notice (which notice must be received by the Administrative Agent
prior to 12:00 Noon, New York City time, three Business Days prior to the
requested Borrowing Date, in the case of Eurodollar Loans, or prior to 9:00

Closing Date. Each borrowing under the Revolving Commitments shall be in an
amount equal to (x) in the case of ABR Loans, $1,000,000 or a multiple of
$500,000 in excess thereof (or, if the then aggregate Available Revolving
Commitments are less than $1,000,000, such lesser amount) and (y) in the case of
Eurodollar Loans, $2,500,000 or a whole multiple of $500,000 in excess thereof.
Upon receipt of any such notice from the Borrower, the Administrative Agent
shall promptly notify each Revolving Lender thereof. Each

                                                                              29

Revolving Lender will make the amount of its PRO RATA share of each borrowing
available to the Administrative Agent for the account of the Borrower at the
Funding Office prior to 12:00 Noon, New York City time, on the Borrowing Date
requested by the Borrower in funds immediately available to the Administrative
Agent. Such borrowing will then be made available to the Borrower by the
Administrative Agent crediting the account of the Borrower on the books of such
office with the aggregate of the amounts made available to the Administrative
Agent by the Revolving Lenders and in like funds as received by the
Administrative Agent.

               2.6 COMMITMENT FEES, ETC. (a) The Borrower agrees to pay to the
Administrative Agent for the account of each Revolving Lender a commitment fee
for the period from and including the Closing Date to the last day of the
Revolving Commitment Period, computed at the Commitment Fee Rate on the average
daily amount of the Available Revolving Commitment of such Lender during the
period for which payment is made, payable quarterly in arrears on the last day
of each March, June, September and December and on the Scheduled Revolving
Termination Date, commencing on the first of such dates to occur after the date
hereof.

               (b The Borrower agrees to pay to the Administrative Agent and the
Other Representatives the fees in the amounts and on the dates previously agreed
to in writing by the Borrower and the Administrative Agent and the other
Representatives, as the case may be.

               2.7 TERMINATION OR REDUCTION OF REVOLVING COMMITMENTS. The
Borrower shall have the right, upon not less than three Business Days' notice to
the Administrative Agent, to terminate the Revolving Commitments or, from time
to time, to reduce the amount of the Revolving Commitments; PROVIDED that no
such termination or reduction of Revolving Commitments shall be permitted if,
after giving effect thereto and to any prepayments of the Revolving Loans made
on the effective date thereof, the Total Revolving Extensions of Credit would
exceed the Total Revolving Commitments. Any such reduction shall be in an amount
equal to $1,000,000, or a whole multiple thereof, and shall reduce permanently
the Revolving Commitments then in effect.

               2.8 OPTIONAL PREPAYMENTS. The Borrower may at any time and from
time to time prepay the Loans, in whole or in part, without premium or penalty,
upon irrevocable notice delivered to the Administrative Agent at least three
Business Days prior thereto in the case of Eurodollar Loans and at least one
Business Day prior thereto in the case of ABR Loans, which notice shall specify
the date and amount of prepayment and whether the prepayment is of Eurodollar
Loans or ABR Loans; PROVIDED, that if a Eurodollar Loan is prepaid on any day
other than the last day of the Interest Period applicable thereto, the Borrower
shall also pay any amounts owing pursuant to Section 2.18. Upon receipt of any
such notice the Administrative Agent shall promptly notify each relevant Lender
thereof. If any such notice is given, the amount specified in such notice shall
be due and payable on the date specified therein, together with (except in the
case of Revolving Loans that are ABR Loans) accrued interest to such date on the
amount prepaid. Partial prepayments of Term Loans and Revolving Loans shall be
in an aggregate principal amount of $2,500,000 or a whole multiple thereof and
shall be applied as set forth in Sections 2.15(b) or (c), as the case may be.

               2.9 MANDATORY PREPAYMENTS AND COMMITMENT REDUCTIONS. (a) If any
Capital Stock shall be issued by Holdings, the Borrower or any of its
Subsidiaries (other than the Capital Stock issued to (i) directors and employees
of Holdings, the Borrower or any of its Subsidiaries under employee benefit
plans, (ii) sellers as consideration in acquisitions of equity or ownership
interests in, or assets of, other Persons, or (iii) existing stockholders of
Holdings or other investors in private placements of the Capital Stock organized
by the Sponsor in connection with the financing of Permitted Acquisitions) an
amount equal to 50% of the Net Cash Proceeds from the issuance of such Capital
Stock shall be applied on the date of such issuance toward the prepayment of the
Term Loans and the reduction of the Revolving Commitments as set forth in
Section 2.9(d). If any Indebtedness shall be incurred by Holdings, the Borrower
or any of its Subsidiaries (other than the Senior Discount Debentures, the
Senior Subordinated Notes, the Senior Discount Debenture Refinancing and other
Indebtedness permitted in accordance with Section 7.2 as in effect on the date
hereof) an amount equal to 100% of the Net Cash Proceeds from the incurrence of
such Indebtedness shall be applied on the date of such issuance or incurrence
toward the prepayment of the Term Loans and the reduction of the Revolving
Commitments as set forth in Section 2.9(d).

               (b If on any date Holdings, the Borrower or any of its
Subsidiaries shall receive Net Cash Proceeds from any Asset Sale or Recovery
Event then, unless a Reinvestment Notice in respect of any Recovery Event shall
be delivered in respect thereof, such Net Cash Proceeds shall be applied on such
date toward the prepayment of the Term Loans and the reduction of the Revolving
Commitments as set forth in Section 2.9(d); PROVIDED, that, notwithstanding the
foregoing, (i) an aggregate amount not to exceed $5,000,000 of Net Cash Proceeds
from Asset Sales in any fiscal year of the Borrower may be retained by Holdings,
the Borrower or any of its Subsidiaries, as the case may be, and (ii) on each
Reinvestment Prepayment Date, an amount equal to the Reinvestment Prepayment
Amount with respect to the relevant Reinvestment Event shall be applied toward
the prepayment of the Term Loans and the reduction of the Revolving Commitments
as set forth in Section 2.9(d).

               (c) If, for any fiscal year of the Borrower commencing with the
fiscal year ending December 31, 2000, there shall be Excess Cash Flow, the
Borrower shall, on the relevant Excess Cash Flow Application Date, apply the ECF
Percentage of such Excess Cash Flow toward the prepayment of the Term Loans and
the reduction of the Revolving Commitments as set forth in Section 2.9(d). Each
such prepayment and commitment reduction shall be made on a date (an "EXCESS
CASH FLOW APPLICATION DATE") no later than five days after the earlier of (i)
the date on which the financial statements of the Borrower referred to in
Section 6.1(a), for the fiscal year with respect to which such prepayment is
made, are required to be delivered to the Lenders and (ii) the date such
financial statements are actually delivered.

               (d) Amounts to be applied in connection with prepayments and
Commitment reductions made pursuant to this Section 2.9 shall be applied, FIRST,
to the prepayment of the Term Loans and, SECOND, to reduce permanently the
Revolving Commitments. Any such reduction of the Revolving Commitments shall be
accompanied by prepayment of the Revolving Loans to the extent, if any, that the
Total Revolving Extensions of Credit exceed the amount of the Total Revolving
Commitments as so reduced, PROVIDED that if the aggregate principal amount of
Revolving Loans then outstanding is less than the amount of such excess (because
L/C

<PAGE>
                                                                              31

Obligations constitute a portion thereof), the Borrower shall, to the extent
of the balance of such excess, replace outstanding Letters of Credit and/or
deposit an amount in cash in a cash collateral account established with the
Administrative Agent for the benefit of the Lenders on terms and conditions
satisfactory to the Administrative Agent.

               The application of any prepayment pursuant to this Section 2.9
shall be made, first, to ABR Loans and, second, to Eurodollar Loans and shall be
applied as set forth in Sections 2.15(b) or (c), as the case may be. Each
prepayment of the Loans under this Section 2.9 (except in the case of Revolving
Loans that are ABR Loans) shall be accompanied by accrued interest to the date
of such prepayment on the amount prepaid.

               2.10 CONVERSION AND CONTINUATION OPTIONS. (a) The Borrower may
elect from time to time to convert Eurodollar Loans to ABR Loans by giving the
Administrative Agent at least two Business Days' prior irrevocable notice of
such election, PROVIDED that any such conversion of Eurodollar Loans may only be
made on the last day of an Interest Period with respect thereto. The Borrower
may elect from time to time to convert ABR Loans to Eurodollar Loans by giving
the Administrative Agent at least three Business Days' prior irrevocable notice
of such election (which notice shall specify the length of the initial Interest
Period therefor), PROVIDED that no ABR Loan under a particular Facility may be
converted into a Eurodollar Loan when any Event of Default has occurred and is
continuing and, so long as any Event of Default has occurred and is continuing,
the Administrative Agent or the Majority Facility Lenders in respect of such
Facility have determined in its or their sole discretion not to permit such
conversions. Upon receipt of any such notice the Administrative Agent shall
promptly notify each relevant Lender thereof.

               (b) Any Eurodollar Loan may be continued as such upon the
expiration of the then current Interest Period with respect thereto by the
Borrower giving irrevocable notice to the Administrative Agent, in accordance
with the applicable provisions of the term "Interest Period" set forth in
Section 1.1, of the length of the next Interest Period to be applicable to such
Loans, PROVIDED that no Eurodollar Loan under a particular Facility may be
continued as such when any Event of Default has occurred and is continuing and,
so long as any Event of Default has occurred and is continuing, the
Administrative Agent has or the Majority Facility Lenders in respect of such
Facility have determined in its or their sole discretion not to permit such
continuations, and PROVIDED, FURTHER, that if the Borrower shall fail to give
any required notice as described above in this paragraph or if such continuation
is not permitted pursuant to the preceding proviso such Loans shall be
automatically converted to ABR Loans on the last day of such then expiring
Interest Period. Upon receipt of any such notice the Administrative Agent shall
promptly notify each relevant Lender thereof.

               2.11 LIMITATIONS ON EURODOLLAR TRANCHES. Notwithstanding anything
to the contrary in this Agreement, all borrowings, conversions and continuations
of Eurodollar Loans hereunder and all selections of Interest Periods hereunder
shall be in such amounts and be made pursuant to such elections so that, (a)
after giving effect thereto, the aggregate principal amount of the Eurodollar
Loans comprising each Eurodollar Tranche shall be equal to $2,500,000 or a whole
multiple of $500,000 in excess thereof and (b) no more than eight Eurodollar
Tranches shall be outstanding at any one time.

                                                                              32


               2.12 INTEREST RATES AND PAYMENT DATES. (a) Each Eurodollar Loan
shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such day
plus the Applicable Margin.

               (b) Each ABR Loan shall bear interest at a rate per annum equal
to the ABR plus the Applicable Margin.

               (c) (i) If all or a portion of the principal amount of any Loan
or Reimbursement Obligation shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), all outstanding Loans and Reimbursement
Obligations (whether or not overdue) shall bear interest at a rate per annum
equal to (x) in the case of the Loans, the rate that would otherwise be
applicable thereto pursuant to the foregoing provisions of this Section PLUS 2%
or (y) in the case of Reimbursement Obligations, the rate applicable to ABR
Loans under the Revolving Facility PLUS 2%, and (ii) if all or a portion of any
interest payable on any Loan or Reimbursement Obligation or any commitment fee
or other amount payable hereunder shall not be paid when due (whether at the
stated maturity, by acceleration or otherwise), such overdue amount shall bear
interest at a rate per annum equal to the rate then applicable to ABR Loans
under the relevant Facility PLUS 2% (or, in the case of any such other amounts
that do not relate to a particular Facility, the rate then applicable to ABR
Loans under the Revolving Facility PLUS 2%), in each case, with respect to
clauses (i) and (ii) above, from the date of such non-payment until such amount
is paid in full (as well after as before judgment).

               (d) Interest shall be payable in arrears on each Interest Payment
Date, PROVIDED that interest accruing pursuant to paragraph (c) of this Section
shall be payable from time to time on demand.

               2.13 COMPUTATION OF INTEREST AND FEES. (a) Interest and fees
payable pursuant hereto shall be calculated on the basis of a 360-day year for
the actual days elapsed, except that, with respect to ABR Loans the rate of
interest on which is calculated on the basis of the Prime Rate, the interest
thereon shall be calculated on the basis of a 365- (or 366-, as the case may be)
day year for the actual days elapsed. The Administrative Agent shall as soon as
practicable notify the Borrower and the relevant Lenders of each determination
of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a
change in the ABR or the Eurocurrency Reserve Requirements shall become
effective as of the opening of business on the day on which such change becomes
effective. The Administrative Agent shall as soon as practicable notify the
Borrower and the relevant Lenders of the effective date and the amount of each
such change in interest rate.

               (b) Each determination of an interest rate by the Administrative
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on the Borrower and the Lenders in the absence of manifest error. The
Administrative Agent shall, at the request of the Borrower, deliver to the
Borrower a statement showing the quotations used by the Administrative Agent in
determining any interest rate pursuant to Section 2.12(a).

                                                                              33


               2.14 INABILITY TO DETERMINE INTEREST RATE. If prior to the first
day of any Interest Period:

               (a) the Administrative Agent shall have determined in good faith
        (which determination shall be conclusive and binding upon the Borrower)
        that, by reason of circumstances affecting the relevant market, adequate
        and reasonable means do not exist for ascertaining the Eurodollar Rate
        for such Interest Period, or

               (b) the Administrative Agent shall have received notice from the
        Majority Facility Lenders in respect of the relevant Facility that the
        Eurodollar Rate determined or to be determined for such Interest Period
        will not adequately and fairly reflect the cost to such Lenders (as
        conclusively certified by such Lenders) of making or maintaining their
        affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the relevant Lenders as soon as practicable thereafter. If such
notice is given (x) any Eurodollar Loans under the relevant Facility requested
to be made on the first day of such Interest Period shall be made as ABR Loans,
(y) any Loans under the relevant Facility that were to have been converted on
the first day of such Interest Period to Eurodollar Loans shall be continued as
ABR Loans and (z) any outstanding Eurodollar Loans under the relevant Facility
shall be converted, on the last day of the then-current Interest Period, to ABR
Loans. Until such notice has been withdrawn by the Administrative Agent, no
further Eurodollar Loans under the relevant Facility shall be made or continued
as such, nor shall the Borrower have the right to convert Loans under the
relevant Facility to Eurodollar Loans.

               2.15 PRO RATA TREATMENT AND PAYMENTS. (a) Each borrowing by the
Borrower from the Lenders hereunder, each payment by the Borrower on account of
any commitment fee and any reduction of the Commitments of the Lenders shall be
made PRO RATA according to the respective Tranche B Term Percentages, Tranche C
Term Percentages or Revolving Percentages, as the case may be, of the relevant
Lenders.

               (b) Each payment (including each prepayment) by the Borrower on
account of principal of and interest on the Tranche B Term Loans or the Tranche
C Term Loans shall be made PRO RATA according to the respective outstanding
principal amounts of the Tranche B Term Loans or the Tranche C Term Loans, as
the case may be, then held by the Term Lenders. Prepayments of the Term Loans
shall be made PRO RATA according to the respective outstanding principal amounts
thereof. The amount of each such principal prepayment shall be applied to reduce
the then remaining installments of the Tranche B Term Loans and Tranche C Term
Loans, as the case may be, PRO RATA. Amounts prepaid on account of the Term
Loans may not be reborrowed.

               (c) Each payment (including each prepayment) by the Borrower on
account of principal of and interest on the Revolving Loans shall be made PRO
RATA according to the respective outstanding principal amounts of the Revolving
Loans then held by the Revolving Lenders.
<PAGE>
                                                                              34

               (d) All payments (including prepayments) to be made by the
Borrower hereunder, whether on account of principal, interest, fees or
otherwise, shall be made without setoff or counterclaim and shall be made prior
to 12:00 Noon, New York City time, on the due date thereof to the Administrative
Agent, for the account of the Lenders, at the Funding Office, in Dollars and in
immediately available funds. The Administrative Agent shall distribute such
payments to the Lenders promptly upon receipt in like funds as received. If any
payment hereunder (other than payments on the Eurodollar Loans) becomes due and
payable on a day other than a Business Day, such payment shall be extended to
the next succeeding Business Day. If any payment on a Eurodollar Loan becomes
due and payable on a day other than a Business Day, the maturity thereof shall
be extended to the next succeeding Business Day unless the result of such
extension would be to extend such payment into another calendar month, in which
event such payment shall be made on the immediately preceding Business Day. In
the case of any extension of any payment of principal pursuant to the preceding
two sentences, interest thereon shall be payable at the then applicable rate
during such extension.

               (e) Unless the Administrative Agent shall have been notified in
writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its share of such borrowing available to the
Administrative Agent, the Administrative Agent may assume that such Lender is
making such amount available to the Administrative Agent, and the Administrative
Agent may, in reliance upon such assumption, make available to the Borrower a
corresponding amount. If such amount is not made available to the Administrative
Agent by the required time on the Borrowing Date therefor, such Lender shall pay
to the Administrative Agent, on demand, such amount with interest thereon at a
rate equal to the daily average Federal Funds Effective Rate for the period
until such Lender makes such amount immediately available to the Administrative
Agent. A certificate of the Administrative Agent submitted to any Lender with
respect to any amounts owing under this paragraph shall be conclusive in the
absence of manifest error. If such Lender's share of such borrowing is not made
available to the Administrative Agent by such Lender within three Business Days
of such Borrowing Date, the Administrative Agent shall also be entitled to
recover such amount with interest thereon at the rate per annum applicable to
ABR Loans under the relevant Facility, on demand, from the Borrower.

               (f) Unless the Administrative Agent shall have been notified in
writing by the Borrower prior to the date of any payment being made hereunder
that the Borrower will not make such payment to the Administrative Agent, the
Administrative Agent may assume that the Borrower is making such payment, and
the Administrative Agent may, but shall not be required to, in reliance upon
such assumption, make available to the Lenders their respective PRO RATA shares
of a corresponding amount. If such payment is not made to the Administrative
Agent by the Borrower within three Business Days of such required date, the
Administrative Agent shall be entitled to recover, on demand, from each Lender
to which any amount which was made available pursuant to the preceding sentence,
such amount with interest thereon at the rate per annum equal to the daily
average Federal Funds Effective Rate. Nothing herein shall be deemed to limit
the rights of the Administrative Agent or any Lender against the Borrower.

               2.16 REQUIREMENTS OF LAW. (a) If the adoption of or any change in
any Requirement of Law or in the interpretation or application thereof or
compliance by any Lender

<PAGE>
                                                                              35

with any request or directive (whether or not having the force of law) from any
central bank or other Governmental Authority made subsequent to the date hereof:

               (i) shall subject any Lender to any tax of any kind whatsoever
        with respect to this Agreement, any Letter of Credit, any Application or
        any Eurodollar Loan made by it, or change the basis of taxation of
        payments to such Lender in respect thereof (except for Non-Excluded
        Taxes covered by Section 2.17 and changes in the rate of tax on the
        overall net income of such Lender);

               (ii) shall impose, modify or hold applicable any reserve, special
        deposit, compulsory loan or similar requirement against assets held by,
        deposits or other liabilities in or for the account of, advances, loans
        or other extensions of credit by, or any other acquisition of funds by,
        any office of such Lender that is not otherwise included in the
        determination of the Eurodollar Rate hereunder; or

               (iii) shall impose on such Lender any other condition; and the
result of any of the foregoing is to increase the cost to such Lender, by an
amount that such Lender deems in good faith to be material, of making,
converting into, continuing or maintaining Eurodollar Loans or issuing or
participating in Letters of Credit, or to reduce any amount receivable hereunder
in respect thereof, then, in any such case, the Borrower shall promptly pay such
Lender, upon its demand, any additional amounts necessary to compensate such
Lender for such increased cost or reduced amount receivable. If any Lender
becomes entitled to claim any additional amounts pursuant to this paragraph, it
shall promptly notify the Borrower (with a copy to the Administrative Agent) of
the event by reason of which it has become so entitled.

               (b) If any Lender shall have determined that the adoption of or
any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under or in respect of any Letter of
Credit to a level below that which such Lender or such corporation reasonably
believes it could have achieved but for such adoption, change or compliance
(taking into consideration such Lender's or such corporation's policies with
respect to capital adequacy) by an amount deemed by such Lender to be material,
then from time to time, after submission by such Lender to the Borrower (with a
copy to the Administrative Agent) of a written request therefor, the Borrower
shall pay to such Lender such additional amount or amounts as will compensate
such Lender for such reduction; PROVIDED that the Borrower shall not be required
to compensate a Lender pursuant to this paragraph for any amounts incurred more
than six months prior to the date that such Lender notifies the Borrower of such
Lender's intention to claim compensation therefor; and PROVIDED FURTHER that, if
the circumstances giving rise to such claim have a retroactive effect, then such
six-month period shall be extended to include the period of such retroactive
effect.

                                                                              36

               (c) A certificate as to any additional amounts payable pursuant
to this Section submitted by any Lender to the Borrower (with a copy to the
Administrative Agent) shall be conclusive in the absence of manifest error. The
obligations of the Borrower pursuant to this Section shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

               2.17 TAXES. (a) All payments made by the Borrower under this
Agreement shall be made free and clear of, and without deduction or withholding
for or on account of, any present or future income, stamp or other taxes,
levies, imposts, duties, charges, fees, deductions or withholdings, now or
hereafter imposed, levied, collected, withheld or assessed by any Governmental
Authority, excluding net income taxes and franchise taxes (imposed in lieu of
net income taxes) imposed on the Administrative Agent or any Lender as a result
of a present or former connection between the Administrative Agent or such
Lender and the jurisdiction of the Governmental Authority imposing such tax or
any political subdivision or taxing authority thereof or therein (other than any
such connection arising solely from the Administrative Agent or such Lender
having executed, delivered or performed its obligations or received a payment
under, or enforced, this Agreement or any other Loan Document). If any such
non-excluded taxes, levies, imposts, duties, charges, fees, deductions or
withholdings ("NON-EXCLUDED TAXES") or Other Taxes are required to be withheld
from any amounts payable to the Administrative Agent or any Lender hereunder,
the amounts so payable to the Administrative Agent or such Lender shall be
increased to the extent necessary to yield to the Administrative Agent or such
Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any
such other amounts payable hereunder at the rates or in the amounts specified in
this Agreement, PROVIDED, HOWEVER, that the Borrower shall not be required to
increase any such amounts payable to any Lender with respect to any Non-Excluded
Taxes (i) that are attributable to such Lender's failure to comply with the
requirements of paragraph (d) or (e) of this Section or (ii) that are United
States withholding taxes imposed on amounts payable to such Lender at the time
the Lender becomes a party to this Agreement, except to the extent that such
Lender's assignor (if any) was entitled, at the time of assignment, to receive
additional amounts from the Borrower with respect to such Non-Excluded Taxes
pursuant to this paragraph.

               (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

               (c) Whenever any Non-Excluded Taxes or Other Taxes are payable by
the Borrower, as promptly as possible thereafter the Borrower shall send to the
Administrative Agent for its own account or for the account of the relevant
Lender, as the case may be, a certified copy of an original official receipt
received by the Borrower showing payment thereof. If the Borrower fails to pay
any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent the required receipts or
other required documentary evidence, the Borrower shall indemnify the
Administrative Agent and the Lenders for any incremental taxes, interest or
penalties that may become payable by the Administrative Agent or any Lender as a
result of any such failure.

               (d) Each Lender (or Transferee) that is not a citizen or resident
of the United States of America, a corporation, partnership or other entity
created or organized in or under the

<PAGE>
                                                                              37

laws of the United States of America (or any jurisdiction thereof), or any
estate or trust that is subject to federal income taxation regardless of the
source of its income (a "NON-U.S. LENDER") shall deliver to the Borrower and the
Administrative Agent (or, in the case of a Participant or an SPC, to the Lender
from which the related participation shall have been purchased or from which the
related option to make Loans shall have been received) two copies of either U.S.
Internal Revenue Service Form 1001 or Form 4224, or, in the case of a Non-U.S.
Lender claiming exemption from U.S. federal withholding tax under Section 871(h)
or 881(c) of the Code with respect to payments of "portfolio interest", a
statement substantially in the form of Exhibit G and a Form W-8, or any
subsequent versions thereof or successors thereto, properly completed and duly
executed by such Non-U.S. Lender claiming complete exemption from, or a reduced
rate of, U.S. federal withholding tax on all payments by the Borrower under this
Agreement and the other Loan Documents. Such forms shall be delivered by each
Non-U.S. Lender on or before the date it becomes a party to this Agreement (or,
in the case of any Participant or SPC, on or before the date such Participant
purchases the related participation or the date such SPC is granted the option
to provide the Loans obligated to be made hereunder by the Granting Bank (as
hereinafter defined)). In addition, each Non-U.S. Lender shall deliver such
forms promptly upon the obsolescence or invalidity of any form previously
delivered by such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify
the Borrower at any time it determines that it is no longer in a position to
provide any previously delivered certificate to the Borrower (or any other form
of certification adopted by the U.S. taxing authorities for such purpose).
Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall
not be required to deliver any form pursuant to this paragraph that such
Non-U.S. Lender is not legally able to deliver.

               (e) A Lender that is entitled to an exemption from or reduction
of non-U.S. withholding tax under the law of the jurisdiction in which the
Borrower is located, or any treaty to which such jurisdiction is a party, with
respect to payments under this Agreement shall deliver to the Borrower (with a
copy to the Administrative Agent), at the time or times prescribed by applicable
law or reasonably requested by the Borrower, such properly completed and
executed documentation prescribed by applicable law as will permit such payments
to be made without withholding or at a reduced rate, PROVIDED that such Lender
is legally entitled to complete, execute and deliver such documentation and in
such Lender's good faith judgment such completion, execution or submission would
not materially prejudice the legal position of such Lender.

               (f) If the Administrative Agent or any Lender receives a refund
in respect of Non-Excluded Taxes or Other Taxes paid by the Borrower, which in
the sole judgment of such Lender is allocable to such payment, it shall promptly
pay such refund, together with any other amounts paid by the Borrower in
connection with such refunded Taxes or Other Taxes, to the Borrower, net of all
out-of-pocket expenses of such Lender incurred in obtaining such refund,
PROVIDED, HOWEVER, that such Borrower agrees to promptly return such refund to
the Administrative Agent or the applicable Lender, as the case may be, if it
receives notice from the Administrative Agent or applicable Lender that such
Administrative Agent or Lender is required to repay such refund.

               (g) The agreements in this Section shall survive the termination
of this Agreement and the payment of the Loans and all other amounts payable
hereunder.

                                                                              38

               2.18 INDEMNITY. The Borrower agrees to indemnify each Lender and
to hold each Lender harmless from any loss or expense that such Lender may
sustain or incur as a consequence of (a) default by the Borrower in making a
borrowing of, conversion into or continuation of Eurodollar Loans after the
Borrower has given a notice requesting the same in accordance with the
provisions of this Agreement, (b) default by the Borrower in making any
prepayment of or conversion from Eurodollar Loans after the Borrower has given a
notice thereof in accordance with the provisions of this Agreement or (c) the
making of a prepayment of Eurodollar Loans on a day that is not the last day of
an Interest Period with respect thereto. Such indemnification may include an
amount equal to the excess, if any, of (i) the amount of interest that would
have accrued on the amount so prepaid, or not so borrowed, converted or
continued, for the period from the date of such prepayment or of such failure to
borrow, convert or continue to the last day of such Interest Period (or, in the
case of a failure to borrow, convert or continue, the Interest Period that would
have commenced on the date of such failure) in each case at the applicable rate
of interest for such Loans provided for herein (excluding, however, the
Applicable Margin included therein, if any) OVER (ii) the amount of interest (as
reasonably determined by such Lender) that would have accrued to such Lender on
such amount by placing such amount on deposit for a comparable period with
leading banks in the interbank eurodollar market. A certificate as to any
amounts payable pursuant to this Section submitted to the Borrower by any Lender
shall be conclusive in the absence of manifest error. This covenant shall
survive the termination of this Agreement and the payment of the Loans and all
other amounts payable hereunder.

               2.19 CHANGE OF LENDING OFFICE. Each Lender agrees that, upon the
occurrence of any event giving rise to the operation of Section 2.16 or 2.17(a)
with respect to such Lender, it will, if requested by the Borrower, use
reasonable efforts (subject to overall policy considerations of such Lender) to
designate another lending office for any Loans affected by such event with the
object of avoiding the consequences of such event; PROVIDED, that such
designation is made on terms that, in the sole good faith judgment of such
Lender, cause such Lender and its lending office(s) to suffer no economic, legal
or regulatory disadvantage, and PROVIDED, FURTHER, that nothing in this Section
shall affect or postpone any of the obligations of any Borrower or the rights of
any Lender pursuant to Section 2.16 or 2.17(a).

               2.20 REPLACEMENT OF LENDERS. The Borrower shall be permitted to
replace any Lender that (a) requests reimbursement for amounts owing pursuant to
Section 2.16 or 2.17(a) or (b) defaults in its obligation to make Loans
hereunder, with a replacement financial institution; PROVIDED that (i) such
replacement does not conflict with any Requirement of Law, (ii) no Event of
Default shall have occurred and be continuing at the time of such replacement,
(iii) prior to any such replacement, such Lender shall have taken no action
under Section 2.19 so as to eliminate the continued need for payment of amounts
owing pursuant to Section 2.16 or 2.17(a), (iv) the replacement financial
institution shall purchase, at par, all Loans and other amounts owing to such
replaced Lender on or prior to the date of replacement, (v) the Borrower shall
be liable to such replaced Lender under Section 2.18 if any Eurodollar Loan
owing to such replaced Lender shall be purchased other than on the last day of
the Interest Period relating thereto, (vi) the replacement financial
institution, if not already a Lender, shall be reasonably satisfactory to the
Administrative Agent, which determination shall not be unreasonably delayed,
(vii) the replaced Lender shall be obligated to make such replacement in
accordance with the provisions

<PAGE>
                                                                              39

of Section 10.6 (provided that the Borrower shall be obligated to pay the
registration and processing fee referred to therein), (viii) until such time as
such replacement shall be consummated, the Borrower shall pay all additional
amounts (if any) required pursuant to Section 2.16 or 2.17(a), as the case may
be, and (ix) any such replacement shall not be deemed to be a waiver of any
rights that the Borrower, the Administrative Agent or any other Lender shall
have against the replaced Lender.

                          SECTION 3. LETTERS OF CREDIT

               3.1 L/C COMMITMENT. (a) Subject to the terms and conditions
hereof, the Issuing Lender, in reliance on the agreements of the other Revolving
Lenders set forth in Section 3.4(a), agrees to issue letters of credit ("LETTERS
OF CREDIT") for the account of the Borrower on any Business Day during the
Revolving Commitment Period in such form as may be approved from time to time by
the Issuing Lender; PROVIDED that the Issuing Lender shall have no obligation to
issue any Letter of Credit if, after giving effect to such issuance, (i) the L/C
Obligations would exceed the L/C Commitment or (ii) the aggregate amount of the
Available Revolving Commitments would be less than zero. Each Letter of Credit
shall (i) be denominated in Dollars and (ii) have a term until expiry (or, if
such Letter of Credit contemplates time drafts, a term through the maximum time
draft period) ending no later than the earlier of (x) the first anniversary of
its date of issuance (except with the consent of the Majority Facility Lenders
in respect of the Revolving Facility) and (y) the date that is five Business
Days prior to the Scheduled Revolving Termination Date, PROVIDED that any Letter
of Credit may provide for the renewal thereof, with or without notice from the
Issuing Lender, for successive periods of up to one year each (which shall in no
event extend beyond the date referred to in clause (y) above).

               (b) The Issuing Lender shall not at any time be obligated to
issue any Letter of Credit hereunder if such issuance would conflict with, or
cause the Issuing Lender or any L/C Participant to exceed any limits imposed by,
any applicable Requirement of Law.

               3.2 PROCEDURE FOR ISSUANCE OF LETTER OF CREDIT. The Borrower may
from time to time request that the Issuing Lender issue a Letter of Credit by
delivering to the Issuing Lender at its address for notices specified herein an
Application therefor, completed to the reasonable satisfaction of the Issuing
Lender, and such other certificates, documents and other papers and information
as the Issuing Lender may reasonably request. Upon receipt of any Application,
the Issuing Lender will promptly process such Application and the certificates,
documents and other papers and information delivered to it in connection
therewith in accordance with its customary procedures and shall promptly issue
the Letter of Credit requested thereby (but in no event shall the Issuing Lender
be required to issue any Letter of Credit earlier than three Business Days after
its receipt of the Application therefor and all such other certificates,
documents and other papers and information relating thereto) by issuing the
original of such Letter of Credit to the beneficiary thereof or as otherwise may
be agreed to by the Issuing Lender and the Borrower. The Issuing Lender shall
furnish a copy of such Letter of Credit to the Borrower promptly following the
issuance thereof. The Issuing Lender shall promptly furnish to the
Administrative Agent, which shall in turn promptly furnish to the Lenders,
notice of the issuance of each Letter of Credit (including the amount thereof).
<PAGE>
                                                                              40

               3.3 FEES AND OTHER CHARGES. (a) The Borrower will pay a fee on
all outstanding Letters of Credit at a per annum rate equal to the Applicable
Margin then in effect with respect to Eurodollar Loans under the Revolving
Facility, shared ratably among the Revolving Lenders and payable quarterly in
arrears on each L/C Fee Payment Date after the issuance date. In addition, the
Borrower shall pay to the Issuing Lender for its own account a fronting fee of
1/8 of 1% per annum on the average daily undrawn and unexpired amount of each
Letter of Credit, payable quarterly in arrears on each L/C Fee Payment Date
after the Issuance Date.

               (b) In addition to the foregoing fees, the Borrower shall pay or
reimburse the Issuing Lender for such normal and customary costs and expenses as
are incurred or charged by the Issuing Lender in issuing, negotiating, effecting
payment under, amending or otherwise administering any Letter of Credit.

               3.4 L/C PARTICIPATIONS. (a) The Issuing Lender irrevocably agrees
to grant and hereby grants to each L/C Participant, and, to induce the Issuing
Lender to issue Letters of Credit hereunder, each L/C Participant irrevocably
agrees to accept and purchase and hereby accepts and purchases from the Issuing
Lender, on the terms and conditions hereinafter stated, for such L/C
Participant's own account and risk an undivided interest equal to such L/C
Participant's Revolving Percentage in the Issuing Lender's obligations and
rights under each Letter of Credit issued hereunder and the amount of each draft
paid by the Issuing Lender thereunder. Each L/C Participant unconditionally and
irrevocably agrees with the Issuing Lender that, if a draft is paid under any
Letter of Credit for which the Issuing Lender is not reimbursed in full by the
Borrower in accordance with the terms of this Agreement (or, if reimbursed, is
required to be returned to the Borrower), such L/C Participant shall pay to the
Issuing Lender upon demand at the Issuing Lender's address for notices specified
herein an amount equal to such L/C Participant's Revolving Percentage of the
amount of such draft, or any part thereof, that is not so reimbursed (or, if
reimbursed, is required to be returned to the Borrower).

               (b) If any amount required to be paid by any L/C Participant to
the Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed
portion of any payment made by the Issuing Lender under any Letter of Credit is
paid to the Issuing Lender within three Business Days after the date such
payment is due, such L/C Participant shall pay to the Issuing Lender on demand
an amount equal to the product of (i) such amount, times (ii) the daily average
Federal Funds Effective Rate during the period from and including the date such
payment is required to the date on which such payment is immediately available
to the Issuing Lender, times (iii) a fraction the numerator of which is the
number of days that elapse during such period and the denominator of which is
360. If any such amount required to be paid by any L/C Participant pursuant to
Section 3.4(a) is not made available to the Issuing Lender by such L/C
Participant within three Business Days after the date such payment is due, the
Issuing Lender shall be entitled to recover from such L/C Participant, on
demand, such amount with interest thereon calculated from such due date at the
rate per annum applicable to ABR Loans under the Revolving Facility. A
certificate of the Issuing Lender submitted to any L/C Participant with respect
to any amounts owing under this Section shall be conclusive in the absence of
manifest error.
<PAGE>
                                                                              41

               (c) Whenever, at any time after the Issuing Lender has made
payment under any Letter of Credit and has received from any L/C Participant its
PRO RATA share of such payment in accordance with Section 3.4(a), the Issuing
Lender receives any payment related to such Letter of Credit (whether directly
from the Borrower or otherwise, including proceeds of collateral applied thereto
by the Issuing Lender), or any payment of interest on account thereof, the
Issuing Lender will distribute to such L/C Participant its PRO RATA share
thereof; PROVIDED, HOWEVER, that in the event that any such payment received by
the Issuing Lender shall be required to be returned by the Issuing Lender, such
L/C Participant shall return to the Issuing Lender the portion thereof
previously distributed by the Issuing Lender to it.

               3.5 REIMBURSEMENT OBLIGATION OF THE BORROWER. The Borrower agrees
to reimburse the Issuing Lender on the Business Day immediately following the
date on which the Issuing Lender notifies the Borrower of the date and amount of
a draft presented under any Letter of Credit and paid by the Issuing Lender for
the amount of (a) such draft so paid and (b) any taxes, fees, charges or other
costs or expenses incurred by the Issuing Lender in connection with such
payment. Each such payment shall be made to the Issuing Lender at its address
for notices specified herein in lawful money of the United States and in
immediately available funds. Interest shall be payable on any and all amounts
remaining unpaid by the Borrower under this Section from the date such amounts
become payable (whether at stated maturity, by acceleration or otherwise) until
payment in full at the rate set forth in (i) until the second Business Day
following the date of the applicable drawing, Section 2.12(b) and (ii)
thereafter, Section 2.12(c).

               3.6 OBLIGATIONS ABSOLUTE. The Borrower's obligations under this
Section 3 shall be absolute and unconditional under any and all circumstances
and irrespective of any setoff, counterclaim or defense to payment that the
Borrower may have or have had against the Issuing Lender, any beneficiary of a
Letter of Credit or any other Person. The Borrower also agrees with the Issuing
Lender that the Issuing Lender shall not be responsible for, and the Borrower's
Reimbursement Obligations under Section 3.5 shall not be affected by, among
other things, the validity or genuineness of documents or of any endorsements
thereon, even though such documents shall in fact prove to be invalid,
fraudulent or forged, or any dispute between or among the Borrower and any
beneficiary of any Letter of Credit or any other party to which such Letter of
Credit may be transferred or any claims whatsoever of the Borrower against any
beneficiary of such Letter of Credit or any such transferee. The Issuing Lender
shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit, except for errors or
omissions resulting from the gross negligence or willful misconduct of the
Issuing Lender. The Borrower agrees that any action taken or omitted by the
Issuing Lender under or in connection with any Letter of Credit or the related
drafts or documents, if done in the absence of gross negligence or willful
misconduct and in accordance with the standards of care specified in the Uniform
Commercial Code of the State of New York, shall be binding on the Borrower and
shall not result in any liability of the Issuing Lender to the Borrower.

               3.7 LETTER OF CREDIT PAYMENTS. If any draft shall be presented
for payment under any Letter of Credit, the Issuing Lender shall promptly notify
the Borrower of the date and amount thereof. The responsibility of the Issuing
Lender to the Borrower in connection with any draft presented for payment under
any Letter of Credit shall, in addition to any payment

<PAGE>
                                                                              42

obligation expressly provided for in such Letter of Credit, be limited to
determining that the documents (including each draft) delivered under such
Letter of Credit in connection with such presentment are substantially in
conformity with such Letter of Credit.

               3.8 APPLICATIONS. To the extent that any provision of any
Application related to any Letter of Credit is inconsistent with the provisions
of this Section 3, the provisions of this Section 3 shall apply.

                    SECTION 4. REPRESENTATIONS AND WARRANTIES

               To induce the Administrative Agent and the Lenders to enter into
this Agreement and to make the Loans and issue or participate in the Letters of
Credit, Holdings and the Borrower hereby jointly and severally represent and
warrant to the Administrative Agent and each Lender that:

               4.1 FINANCIAL CONDITION. (a) The unaudited PRO FORMA consolidated
balance sheets of Holdings and its consolidated Subsidiaries and the Borrower
and its consolidated Subsidiaries, respectively, as at March 31, 1999 (including
the notes thereto) (the "PRO FORMA BALANCE SHEETS"), copies of which have
heretofore been furnished to each Lender, have been prepared giving effect (as
if such events had occurred on such date) to (i) the consummation of the
Transactions (as hereinafter defined), (ii) the Loans to be made hereunder and
the Senior Discount Debentures and the Senior Subordinated Notes to be issued on
the Closing Date and the use of proceeds thereof and (iii) the payment of fees
and expenses in connection with the foregoing. The Pro Forma Balance Sheets have
been prepared based on the best information available to Holdings or the
Borrower as of the date of delivery thereof, and present fairly on a PRO FORMA
basis the estimated financial position of Holdings and its consolidated
Subsidiaries and the Borrower and its consolidated Subsidiaries, respectively,
as at March 31, 1999, assuming that the events specified in the preceding
sentence had actually occurred at such date.

               (b) The audited consolidated balance sheets of Holdings as at
December 31, 1998, and the related consolidated statements of income and of cash
flows for the fiscal year ended on such date, reported on by and accompanied by
an unqualified report from Arthur Andersen LLP, present fairly the consolidated
financial condition of Holdings as at such date, and the consolidated results of
its operations and its consolidated cash flows for the fiscal year then ended.
The unaudited consolidating statements of income for the fiscal year ending
December 31, 1998 and for the three-month period ending March 31, 1999, as the
case may be, present fairly the financial condition of each business unit of
Holdings. The unaudited consolidated balance sheets of Holdings as at March 31,
1999, and the related unaudited consolidated statements of income and of cash
flows for the three-month period ended on such date, present fairly the
consolidated financial condition of Holdings as at such date, and the
consolidated results of its operations and its consolidated cash flows for the
three-month period then ended (subject to normal year-end audit adjustments).
The unaudited monthly consolidated balance sheets of Holdings as at the end of
each month following March 31, 1999 up to the Closing Date, and the related
unaudited monthly consolidated statements of income and of cash flows for the
respective one-month periods ended on such dates, to the extent such monthly
financial statements are available, present fairly the consolidated financial
condition of Holdings

<PAGE>
                                                                              43

as at such dates, and the consolidated results of its operations and its
consolidated cash flows for the respective one-month periods then ended (subject
to normal year-end audit adjustments). All such financial statements, including
the related schedules and notes thereto, have been prepared in accordance with
GAAP applied consistently throughout the periods involved (except as approved by
the aforementioned firm of accountants and disclosed therein) and comply as to
form in all material respects with the published rules and regulations of the
SEC with respect thereto. Holdings and its Subsidiaries do not have any material
Guarantee Obligations, contingent liabilities and liabilities for taxes, or any
long-term leases or unusual forward or long-term commitments, including any
interest rate or foreign currency swap or exchange transaction or other
obligation in respect of derivatives, that are not reflected in the most recent
financial statements referred to in this paragraph. During the period from March
31, 1999 to and including the date hereof there has been no Disposition by
Holdings of any material part of its business or property.

               4.2 NO CHANGE. Since December 31, 1998 there has been no
development or event that has had or is reasonably expected to have a Material
Adverse Effect.

               4.3 CORPORATE EXISTENCE; COMPLIANCE WITH LAW. Each of Holdings,
the Borrower and its Subsidiaries (a) is duly organized, validly existing and in
good standing under the laws of the jurisdiction of its organization, (b) has
the corporate power and authority, and the legal right, to own and operate its
property, to lease the property it operates as lessee and to conduct the
business in which it is currently engaged, (c) is duly qualified as a foreign
corporation and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of property or the conduct of its business
requires such qualification, except to the extent that the failure to qualify as
a foreign corporation or be in good standing could not reasonably be expected to
have a Material Adverse Effect and (d) is in compliance with all Requirements of
Law except to the extent that the failure to comply therewith could not, in the
aggregate, reasonably be expected to have a Material Adverse Effect.

               4.4 CORPORATE POWER; AUTHORIZATION; ENFORCEABLE OBLIGATIONS. Each
Loan Party has the corporate power and authority, and the legal right, to make,
deliver and perform the Loan Documents to which it is a party and, in the case
of the Borrower, to borrow hereunder. Each Loan Party has taken all necessary
corporate action to authorize the execution, delivery and performance of the
Loan Documents to which it is a party and, in the case of the Borrower, to
authorize the borrowings on the terms and conditions of this Agreement. No
consent or authorization of, filing with, notice to or other act by or in
respect of, any Governmental Authority or any other Person is required in
connection with the Acquisition and the borrowings hereunder or with the
execution, delivery, performance, validity or enforceability of this Agreement
or any of the Loan Documents, except (i) consents, authorizations, filings and
notices described in Schedule 4.4, which consents, authorizations, filings and
notices have been obtained or made and are in full force and effect and (ii) the
filings referred to in Section 4.19. Each Loan Document has been duly executed
and delivered on behalf of each Loan Party party thereto. This Agreement
constitutes, and each other Loan Document upon execution will constitute, a
legal, valid and binding obligation of each Loan Party party thereto,
enforceable against each such Loan Party in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of

<PAGE>
                                                                              44

creditors' rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

               4.5 NO LEGAL BAR. The execution, delivery and performance of this
Agreement and the other Loan Documents, the issuance of Letters of Credit, the
borrowings hereunder and the use of the proceeds thereof will not violate or
conflict with any Requirement of Law or any material Contractual Obligation of
Holdings, the Borrower or any of its Subsidiaries and will not result in, or
require, the creation or imposition of any Lien on any of their respective
properties or revenues pursuant to any Requirement of Law or any such
Contractual Obligation (other than the Liens created by the Security Documents).

               4.6 LITIGATION. No litigation, investigation or proceeding of or
before any arbitrator or Governmental Authority is pending or, to the knowledge
of Holdings or the Borrower, threatened by or against Holdings, the Borrower or
any of its Subsidiaries or against any of their respective properties or
revenues (a) with respect to any of the Loan Documents or any of the
transactions contemplated hereby or thereby, or (b) that is reasonably expected
to have a Material Adverse Effect.

               4.7 NO DEFAULT. Neither Holdings, the Borrower nor its respective
Subsidiaries is in default under or with respect to any of its Contractual
Obligations in any respect that is reasonably expected to have a Material
Adverse Effect. No Default or Event of Default has occurred and is continuing.

               4.8 OWNERSHIP OF PROPERTY; LIENS. Each of Holdings, the Borrower
and its Subsidiaries has title in fee simple to, or a valid leasehold interest
in, all its real property, and good title to, or a valid leasehold interest in,
all its other material property, and none of such property is subject to any
Lien except as permitted by Section 7.3.

               4.9 INTELLECTUAL PROPERTY. Each of Holdings, the Borrower and
each of its Subsidiaries owns, or is licensed to use, all Intellectual Property
material in the conduct of its business as currently conducted. No material
claim has been asserted and is pending by any Person challenging or questioning
the use of any Intellectual Property or the validity or effectiveness of any
Intellectual Property, nor does Holdings or the Borrower know of any valid basis
for any such claim. The use of Intellectual Property by Holdings, the Borrower
and its Subsidiaries does not, to Borrower's knowledge, infringe on the rights
of any Person in any material respect.

               4.10 TAXES. Each of Holdings, the Borrower and each of its
Subsidiaries has filed or caused to be filed all Federal, state and other
material tax returns that are required to be filed and has paid all taxes shown
to be due and payable on said returns or on any assessments made against it or
any of its property and all other taxes, fees or other charges imposed on it or
any of its property by any Governmental Authority (other than any the amount or
validity of that are currently being contested in good faith by appropriate
proceedings and with respect to which reserves in conformity with GAAP have been
provided on the books of Holdings, the Borrower or its Subsidiaries, as the case
may be); no tax Lien has been filed, and, to the knowledge of Holdings or the
Borrower, no claim is being asserted, with respect to any such tax, fee or other

<PAGE>
                                                                              45

charge. Such tax returns accurately reflect in all material respects all
liability for taxes of Holdings, the Borrower and its Subsidiaries for the
periods covered thereby.

               4.11 FEDERAL REGULATIONS. No part of the proceeds of any Loans
will be used for "buying" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulation U in any manner that
violates the provisions of the Regulations of the Board. On the Closing Date,
the Borrower will furnish to the Administrative Agent and each Lender a
statement to the foregoing effect in conformity with the requirements of FR Form
G-3 or FR Form U-1, as applicable, referred to in Regulation U.

               4.12 LABOR MATTERS. Except as, in the aggregate, could not
reasonably be expected to have a Material Adverse Effect: (a) there are no
strikes or other labor disputes against Holdings, the Borrower or any of its
Subsidiaries pending or, to the knowledge of Holdings or the Borrower,
threatened; (b) hours worked by and payment made to employees of Holdings, the
Borrower or any of its Subsidiaries have not been in violation of the Fair Labor
Standards Act or any other applicable Requirement of Law dealing with such
matters; and (c) all payments due from Holdings, the Borrower or any of its
Subsidiaries on account of employee health and welfare insurance have been paid
or accrued as a liability on the books of Holdings, the Borrower or the relevant
Subsidiary.

               4.13 ERISA. Neither a Reportable Event nor an "Accumulated
funding deficiency" (within the meaning of Section 412 of the Code or Section
302 of ERISA) has occurred during the five-year period prior to the date on
which this representation is made or deemed made with respect to any Plan, and
each Plan has complied in all material respects with the applicable provisions
of ERISA and the Code. No termination of a Single Employer Plan has occurred,
and no Lien in favor of the PBGC or a Plan has arisen, during such five-year
period. The present value of all accrued benefits under each Single Employer
Plan (based on those assumptions used to fund such Plans) did not, as of the
last annual valuation date prior to the date on which this representation is
made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits by a material amount. Neither the Borrower nor any
Commonly Controlled Entity has had a complete or partial withdrawal from any
Multiemployer Plan that has resulted or could reasonably be expected to result
in a material liability under ERISA, and neither the Borrower nor any Commonly
Controlled Entity would become subject to any material liability under ERISA if
the Borrower or any such Commonly Controlled Entity were to withdraw completely
from all Multiemployer Plans as of the valuation date most closely preceding the
date on which this representation is made or deemed made. No such Multiemployer
Plan is in Reorganization or Insolvent.

               4.14 INVESTMENT COMPANY ACT; OTHER REGULATIONS. No Loan Party is
an "investment company", or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended. No Loan
Party is subject to regulation under any Requirement of Law (other than
Regulation X of the Board) that limits its ability to incur Indebtedness.

               4.15 SUBSIDIARIES. Except as disclosed to the Administrative
Agent by the Borrower in writing from time to time after the Closing Date, (a)
Schedule 4.15 sets forth the name and jurisdiction of incorporation of each
Subsidiary and, as to each such Subsidiary, the

                                                                              46

percentage of each class of Capital Stock owned by any Loan Party and (b) there
are no outstanding subscriptions, options, warrants, calls, rights or other
agreements or commitments (other than stock options granted to employees or
directors and directors' qualifying shares) of any nature relating to any
Capital Stock of the Borrower or any Subsidiary, except as created by the Loan
Documents.

               4.16 USE OF PROCEEDS. The proceeds of the Term Loans shall be
used to finance a portion of the Transactions and to pay related fees and
expenses. The proceeds of the Revolving Loans, and the Letters of Credit, shall
be used for general corporate purposes, including to finance the working capital
needs of the Borrower and its Subsidiaries and, subject to Section 7.8, their
acquisitions of Capital Stock or ownership interests of, and investments in,
other Persons.

               4.17 ENVIRONMENTAL MATTERS. Except as, in the aggregate, could
not reasonably be expected to have a Material Adverse Effect:

               (a) the facilities and properties owned, leased or operated by
        Holdings, the Borrower or any of its Subsidiaries (the "PROPERTIES") do
        not contain, and have not previously contained, any Materials of
        Environmental Concern in amounts or concentrations or under
        circumstances that constitute or constituted a violation of, or could
        reasonably be expected to give rise to liability under, any
        Environmental Law;

               (b) neither Holdings, the Borrower nor any of its Subsidiaries
        has received or is aware of any notice of violation, alleged violation,
        non-compliance, liability or potential liability regarding environmental
        matters or compliance with Environmental Laws with regard to any of the
        Properties or the business operated by Holdings, the Borrower or any of
        its Subsidiaries (the "BUSINESS"), nor does Holdings or the Borrower
        have knowledge or reason to believe that any such notice will be
        received or is being threatened;

               (c) Materials of Environmental Concern have not been transported
        or disposed of from the Properties in violation of, or in a manner or to
        a location that could reasonably be expected to give rise to liability
        under, any Environmental Law, nor have any Materials of Environmental
        Concern been generated, treated, stored or disposed of at, on or under
        any of the Properties in violation of, or in a manner that could give
        rise to liability under, any applicable Environmental Law;

               (d) no judicial proceeding or governmental or administrative
        action is pending or, to the knowledge of Holdings or the Borrower,
        threatened, under any Environmental Law to which Holdings, the Borrower

        consent decrees or other decrees, consent orders, administrative orders
        or other orders, or other administrative or judicial requirements
        outstanding under any Environmental Law with respect to the Properties
        or the Business;

               (e) there has been no release or threat of release of Materials
        of Environmental Concern at or from the Properties, or arising from or

<PAGE>
                                                                              47


        in connection with the Business, in violation of or in amounts or in a

               4.18 ACCURACY OF INFORMATION, ETC. No statement or information
contained in this Agreement, any other Loan Document, the Confidential
Information Memorandum or any other document, certificate or written statement
furnished by or on behalf of any Loan Party to the Administrative Agent or the
Lenders, or any of them (including, without limitation, the Proxy Statement),
for use in connection with the transactions contemplated by this Agreement or
the other Loan Documents, contained as of the date such statement, information,
document or certificate was so furnished (or, in the case of the Confidential
Information Memorandum and the Proxy Statement, as of the date of this
Agreement), any untrue statement of a material fact or omitted to state a
material fact necessary to make the statements contained herein or therein not
misleading, PROVIDED, that with respect to any statement or information
furnished on behalf of any Loan Party by any other Person that is not a Loan
Party, the representation and warranty set forth in this Section 4.18 is limited
to the such Loan Party's best knowledge. The projections and PRO FORMA financial
information contained in the materials referenced above are based upon good
faith estimates and assumptions believed by management of Holdings and the
Borrower to be reasonable at the time made, it being recognized by the Lenders
that such financial information as it relates to future events is not to be
viewed as fact and that actual results during the period or periods covered by
such financial information may differ from the projected results set forth
therein by a material amount. As of the date hereof, the representations and
warranties contained in the Acquisition Documentation and the Proxy Statement
are true and correct in all material respects. There is no fact known to any
Loan Party that is reasonably expected to have a Material Adverse Effect that
has not been expressly disclosed herein, in the other Loan Documents, in the
Confidential Information Memorandum or in any other documents, certificates and
statements furnished to the Administrative Agent and the Lenders (including,
without limitation, the Proxy Statement) for use in connection with the
transactions contemplated hereby and by the other Loan Documents.

               4.19 SECURITY DOCUMENTS. (a) The Guarantee and Collateral
Agreement is effective to create in favor of the Administrative Agent, for the
benefit of the Lenders, a legal, valid and enforceable security interest in the
Collateral described therein, all rights, title or interest thereto and proceeds
thereof. In the case of the Pledged Stock described in the Guarantee and
Collateral Agreement, when stock certificates representing such Pledged Stock
are delivered to the Administrative Agent, and in the case of the other
Collateral described in the Guarantee and Collateral Agreement, when financing
statements and other filings specified on Schedule 4.19 in appropriate form are
filed in the offices specified on Schedule 4.19, the Guarantee and Collateral
Agreement shall constitute a fully perfected Lien on, and security interest in,
all right,

<PAGE>
                                                                              48

title and interest of the Loan Parties in such Collateral and the proceeds
thereof, as security for the Obligations (as defined in the Guarantee and
Collateral Agreement), in each case prior and superior in right to any other
Person (except, in the case of Collateral other than Pledged Stock, Liens
permitted by Section 7.3).

               (b) Schedule 4.19(b) lists each of the real properties in the
United States owned in fee simple by the Borrower or any of its Subsidiaries on
the Closing Date. No Liens or Mortgages shall be created under this Agreement
on, and no Lenders shall have any security interests in, the real property owned
on the Closing Date by the Borrower or any of its Subsidiaries.

               4.20 SOLVENCY. Each Loan Party is, and after giving effect to the
Acquisition and the incurrence of all Indebtedness and obligations being
incurred in connection herewith and therewith will be and will continue to be,
Solvent.

               4.21 SENIOR INDEBTEDNESS. The Obligations constitute "Senior
Indebtedness" of the Borrower under and as defined in the Senior Subordinated
Note Indenture. The obligations of each Subsidiary Guarantor under the Guarantee
and Collateral Agreement constitute "Guarantor Senior Indebtedness" of such
Subsidiary Guarantor under and as defined in the Senior Subordinated Note
Indenture.

               4.22 YEAR 2000 MATTERS. Any reprogramming required to permit the
proper functioning (but only to the extent that such proper functioning would
otherwise be impaired by the occurrence of the year 2000) in and following the
year 2000 of computer systems and other equipment containing embedded
microchips, in either case owned or operated by Holdings, the Borrower or any of
its Subsidiaries or used or relied upon in the conduct of and material to their
business (including any such systems and other equipment supplied by others or
with which the computer systems of Holdings, the Borrower or any of its
Subsidiaries interface), and the testing of all such systems and other equipment
as so reprogrammed, will be completed by October 31, 1999. The costs to
Holdings, the Borrower and its Subsidiaries that have not been incurred as of
the date hereof for such reprogramming and testing and for the other reasonably
foreseeable consequences to them of any improper functioning of other material
computer systems and equipment containing embedded microchips due to the
occurrence of the year 2000 could not reasonably be expected to result in a
Default or Event of Default or to have a Material Adverse Effect. Except for any
reprogramming referred to above, the computer systems of Holdings, the Borrower
and its Subsidiaries material to each of their respective businesses are and,
with ordinary course upgrading and maintenance, will continue for the term of
this Agreement to be, sufficient for the conduct of their business as currently
conducted.

               4.23 INSURANCE. The insurance maintained by or reserved against
on the books of Holdings, the Borrower and its Subsidiaries is sufficient to
protect Holdings, the Borrower and its Subsidiaries against such risks as are
usually insured against in the same general area by companies engaged in the
same or similar business. None of the Loan Parties or any of their Subsidiaries
is in default under any provisions of any such policy of insurance the result of
which could reasonably be expected to cause a cancellation of such policy of
insurance or to limit or delay the entitlement to any payment thereunder or has
received notice of cancellation of any

<PAGE>
                                                                              49

such insurance (other than in connection with the replacement of any such
policy). None of the Loan Parties or any of their Subsidiaries has made any
material claims under any policy of insurance with respect to which the
insurance carrier has denied liability.

               4.24 CERTAIN DOCUMENTS. The Borrower has delivered to the
Administrative Agent a complete and correct copy of each Acquisition
Documentation, the Senior Subordinated Note Indenture, the Senior Discount
Debenture Purchase Agreement, the Senior Discount Debenture Indenture, the Proxy
Statement and all other documents reasonably requested by the Administrative
Agent, including any amendments, supplements or modifications with respect to
any of the foregoing.

                         SECTION 5. CONDITIONS PRECEDENT

               5.1 CONDITIONS TO INITIAL EXTENSION OF CREDIT. The agreement of
each Lender to make the initial extension of credit requested to be made by it
is subject to the satisfaction, prior to or concurrently with the making of such
extension of credit on the Closing Date, of the following conditions precedent:

               (a) CREDIT AGREEMENT; GUARANTEE AND COLLATERAL AGREEMENT. The
        Administrative Agent shall have received (i) this Agreement, executed
        and delivered by the Administrative Agent, Holdings, the Borrower and
        each Person listed on Schedule 1.1A, (ii) each Note requested by a
        Lender, the Guarantee and Collateral Agreement, executed and delivered
        by Holdings, the Borrower and each Subsidiary Guarantor, (iii) an
        Acknowledgment and Consent in the form attached to the Guarantee and
        Collateral Agreement, executed and delivered by each Issuer (as defined
        therein), if any, that is not a Loan Party, and (iv) in the
        circumstances referred to in Section 5.1(c)(ii), the Escrow Agreement,
        executed and delivered by the Borrower and the Administrative Agent.

                      In the event that this Agreement has not been duly
        executed and delivered by each Person listed on Schedule 1.1A on the
        date scheduled to be the Closing Date, the condition referred to in
        clause (i) above shall nevertheless be deemed satisfied if on such date
        the Borrower and the Administrative Agent shall have designated one or
        more Persons (the "DESIGNATED LENDERS") to assume, in the aggregate, all
        of the Commitments that would have been held by the Persons listed on
        Schedule 1.1A (the "NON-EXECUTING PERSONS") which have not so executed
        and delivered this Agreement (subject to each such Designated Lender's
        consent and its execution and delivery of this Agreement). Schedule 1.1A
        shall automatically be deemed to be amended to reflect the respective
        Commitments of the Designated Lenders and the omission of the
        Non-Executing Persons as Lenders hereunder.

               (b) ACQUISITION, ETC. The following transactions shall have been
        consummated, in each case on terms and conditions reasonably
        satisfactory to the Lenders:

                      (i) The transactions contemplated by the Acquisition
               Documentation shall have been consummated in substantially the
               manner set forth therein, and the Administrative Agent shall have

               its assets, including, without limitation, the stock of its
               Subsidiaries, as consideration for all of the Borrower's Capital
               Stock (the "CONTRIBUTION"), and (B) the Administrative Agent
               shall have received a true and correct copy, certified as to
               authenticity by Holdings and the Borrower, of the documentation
               evidencing such Contribution;

                      (iii) Newco shall have received from (A) the Sponsor at
               least $370,100,000 (in cash and in value as a rollover of
               existing equity interests in Holdings prior to the Acquisition)
               and (B) the Other Investors at least $23,000,000 (in cash and in
               value as a rollover of existing equity interests in Holdings
               prior to the Acquisition) from the proceeds of equity issued by
               it;

                      (iv) the Borrower shall have received at least
               $190,000,000 in gross cash proceeds from the issuance of the
               Senior Subordinated Notes and shall have used all such proceeds
               to consummate the Transactions;

                      (v) Holdings shall have received at least $110,000,000 in
               gross cash proceeds from the issuance of the Senior Discount
               Debentures, the terms of which shall not require any payment of
               interest for at least five years from the Closing Date, and shall
               have used all such proceeds to consummate the Transactions;

                      (vi) FFT shall own approximately seven percent (7%) of the
               Capital Stock of Holdings after the Acquisition with an aggregate
               value of approximately $30,600,000;

                      (vii) the Administrative Agent shall have received
               satisfactory evidence that the fees and expenses to be incurred
               in connection with the Acquisition and the financing thereof
               shall not exceed $45,000,000 in the aggregate; and

                       (viii) The Administrative Agent shall have received
               satisfactory evidence that (A) the $100,000,000 Amended and
               Restated Credit Agreement, dated as of February 20, 1998, among
               Holdings, the lenders therein, First Union National Bank, as
               administrative agent thereunder, and Fleet National Bank, as
               documentation agent thereunder, and (B) all other Indebtedness of
               Holdings and its Subsidiaries (other than amounts outstanding
               under the Convertible Subordinated Notes as permitted hereunder)
               shall have been repaid, redeemed, repurchased or terminated and
               all amounts payable in connection therewith shall have been
               indefeasibly paid in full (the "REFINANCING", together with the
               Acquisition and the Contribution, collectively, the
               "TRANSACTIONS"), and satisfactory arrangements shall have been
               made for the termination of all Liens granted in connection
               therewith.
<PAGE>
                                                                              51

        Immediately after the Closing Date, neither Holdings nor the Borrower
        nor any of their respective Subsidiaries shall have any Indebtedness
        other than (A) the remaining Indebtedness outstanding under the
        Convertible Subordinated Notes after the consummation of the Repurchase
        Offer as set forth herein, (B) the Senior Subordinated Notes, (C) the
        Senior Discount Debentures and (D) the Term Loans.

               (c) CONVERTIBLE SUBORDINATED NOTES. (i) The Lenders shall have
        received satisfactory evidence that (A) Holdings shall have commenced an
        offer to repurchase each of the Convertible Subordinated Notes from the
        holders thereof (the "REPURCHASE OFFER") at a cash price of
        approximately equal to 100% of the principal amount of the respective
        Convertible Subordinated Notes (the "REPURCHASE PRICE"), (B) Holdings
        shall have accepted, or shall have confirmed to the Administrative
        Agent, to its reasonable satisfaction, for the benefit of the Lenders,
        its intention to accept, the tender of the Convertible Subordinated
        Notes by the selling holders of such Convertible Subordinated Notes on
        the Closing Date, and (C) simultaneously with the making of the Term
        Loans by the Lenders on the Closing Date, the Administrative Agent shall
        have received instructions from the Borrower to transfer a portion of
        the proceeds of the Loans made on the Closing Date equal to the amount
        of the maximum possible Repurchase Price, either (x) directly to the
        applicable depositary agent to pay for the Convertible Subordinated
        Notes tendered pursuant to the Repurchase Offer (and, to the extent such
        portion is not used by such depositary agent for such purpose and to the
        extent further contemplated by clause (ii) below, for transfer by such
        depositary agent to the Escrow Account (as defined below)) or (y) to the
        Escrow Account.

               (ii) In the event the aggregate principal amount of the
        Convertible Subordinated Notes not tendered and accepted in the
        Repurchase Offer on the Closing Date exceeds $5,000,000, the Borrower
        shall have given instructions to the depositary agent referred to above,
        in a manner satisfactory to the Administrative Agent, or to the
        Administrative Agent, to deposit into a cash collateral account (the
        "ESCROW ACCOUNT") established with the Escrow Agent and governed by the
        Escrow Agreement, substantially in the form of Exhibit E, a portion of
        the proceeds of the Loans made on the Closing Date equal to such
        aggregate principal amount, which amount may be used as provided in the
        Escrow Agreement to pay interest due and payable under each of the
        Convertible Subordinated Notes and for the repurchase of any Convertible
        Subordinated Notes outstanding in the Repurchase Offer and in an offer
        made upon a "Change of Control" of Holdings (as defined in the
        respective indenture for the Convertible Subordinated Notes) or
        otherwise.

               (d) PRO FORMA BALANCE SHEETS; FINANCIAL STATEMENTS. The Lenders
        shall have received satisfactory (i) Pro Forma Balance Sheets, (ii)
        audited consolidated balance sheets of Holdings as at December 31, 1998,

        the fiscal year ended on such date, reported on by and accompanied by an
        unqualified report from Arthur Andersen LLP, (iii) unaudited

        income and of cash flows for the three-month period ended on such date,
        (v) unaudited consolidating statements of income of Holdings (calculated
        on a business unit basis) for the three-month period ended on March 31,

        as at the end of each month following March 31, 1999 up to the Closing
        Date, and the related unaudited monthly consolidated statements of
        income and of cash flows for the respective one-month periods ended on
        such dates, to the extent such monthly financial statements are
        available.

               (e) APPROVALS. All governmental and third party approvals
        necessary or in the reasonable judgment of the Administrative Agent,
        advisable in connection with the Transactions, the continuing operations
        of Holdings, the Borrower and its Subsidiaries and the financings and
        transactions contemplated hereby shall have been obtained and be in full

hereunder (with accrued interest thereon) and all other amounts owing under this
Agreement and the other Loan Documents (including all amounts of L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters of
Credit shall have presented the documents required thereunder) shall immediately
become due and payable, and (B) if such event is any other Event of Default,
either or both of the following actions may be taken: (i) with the consent of
the Required Lenders, the Administrative Agent may, or upon the request of the
Required Lenders, the Administrative Agent shall, by notice to the Borrower
declare the Revolving Commitments to be terminated forthwith, whereupon the
Revolving

<PAGE>
                                                                              75

Commitments shall immediately terminate; and (ii) with the consent of the
Required Lenders, the Administrative Agent may, or upon the request of the
Required Lenders, the Administrative Agent shall, by notice to the Borrower,
declare the Loans hereunder (with accrued interest thereon) and all other
amounts owing under this Agreement and the other Loan Documents (including all
amounts of L/C Obligations, whether or not the beneficiaries of the then
outstanding Letters of Credit shall have presented the documents required
thereunder) to be due and payable forthwith, whereupon the same shall
immediately become due and payable. With respect to all Letters of Credit with
respect to which presentment for honor shall not have occurred at the time of an
acceleration pursuant to this paragraph, the Borrower shall at such time deposit
in a cash collateral account opened by the Administrative Agent an amount equal
to the aggregate then undrawn and unexpired amount of such Letters of Credit.
Amounts held in such cash collateral account shall be applied by the
Administrative Agent to the payment of drafts drawn under such Letters of
Credit, and the unused portion thereof after all such Letters of Credit shall
have expired or been fully drawn upon, if any, shall be applied to repay other
obligations of the Borrower hereunder and under the other Loan Documents
PROVIDED, HOWEVER, that in the event any and all Events of Default shall have
been waived or cured prior to the application of all amounts held in such cash
collateral account to the payment of drafts drawn under such Letters of Credit
or the repayment of other obligations of the Borrower hereunder and under the
other Loan Documents, such remaining amounts in such cash collateral account
shall be paid back to the Borrower. After all such Letters of Credit shall have
expired or been fully drawn upon, all Reimbursement Obligations shall have been
satisfied and all other obligations of the Borrower hereunder and under the
other Loan Documents shall have been paid in full, the balance, if any, in such
cash collateral account shall be returned to the Borrower (or such other Person
as may be lawfully entitled thereto). Except as expressly provided above in this
Section, presentment, demand, protest and all other notices of any kind are
hereby expressly waived by the Borrower.

                              SECTION 9. THE AGENTS

               9.1 APPOINTMENT. Each Lender hereby irrevocably designates and
appoints the Administrative Agent as the agent of such Lender under this
Agreement and the other Loan Documents, and each such Lender irrevocably
authorizes the Administrative Agent, in such capacity, to take such action on
its behalf under the provisions of this Agreement and the other Loan Documents
and to exercise such powers and perform such duties as are expressly delegated
to the Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein or in the other Loan Documents, or any fiduciary
relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the
Administrative Agent.

               9.2 DELEGATION OF DUTIES. The Administrative Agent may execute
any of its duties under this Agreement and the other Loan Documents by or
through agents or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agents or attorneys
in-fact selected by it with reasonable care.

<PAGE>
                                                                              76

               9.3 EXCULPATORY PROVISIONS. Neither any Agent nor any Co-Lead
Arranger nor any of their respective officers, directors, employees, agents,
attorneys-in-fact or affiliates shall be (i) liable for any action lawfully
taken or omitted to be taken by it or such Person under or in connection with
this Agreement or any other Loan Document (except to the extent that any of the
foregoing are found by a final and nonappealable decision of a court of
competent jurisdiction to have resulted from its or such Person's own gross
negligence or willful misconduct) or (ii) responsible in any manner to any of
the Lenders for any recitals, statements, representations or warranties made by
any Loan Party or any officer thereof contained in this Agreement or any other
Loan Document or in any certificate, report, statement or other document
referred to or provided for in, or received by any of the Agents or the Co-Lead
Arrangers under or in connection with, this Agreement or any other Loan Document
or for the value, validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any other Loan Document or for any failure of
any Loan Party a party thereto to perform its obligations hereunder or
thereunder. The Agents shall not be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of any Loan Party.

               9.4 RELIANCE BY ADMINISTRATIVE AGENT. The Administrative Agent
shall be entitled to rely, and shall be fully protected in relying, upon any
instrument, writing, resolution, notice, consent, certificate, affidavit,
letter, telecopy, telex or teletype message, statement, order or other document
or conversation believed by it to be genuine and correct and to have been
signed, sent or made by the proper Person or Persons and upon advice and
statements of legal counsel (including counsel to Holdings or the Borrower),
independent accountants and other experts selected by the Administrative Agent.
The Administrative Agent may deem and treat the payee of any Note as the owner
thereof for all purposes unless a written notice of assignment, negotiation or
transfer thereof shall have been filed with the Administrative Agent. The
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Required Lenders (or, if so specified
by this Agreement, all Lenders) as it deems appropriate or it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense that may be incurred by it by reason of taking or continuing to take any
such action. The Administrative Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement and the other Loan
Documents in accordance with a request of the Required Lenders (or, if so
specified by this Agreement, all Lenders), and such request and any action taken
or failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Loans.

               9.5 NOTICE OF DEFAULT. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless the Administrative Agent has received notice from a
Lender, Holdings or the Borrower referring to this Agreement, describing such
Default or Event of Default and stating that such notice is a "notice of
default". In the event that the Administrative Agent receives such a notice, the
Administrative Agent shall give notice thereof to the Lenders. The
Administrative Agent shall take such action with respect to such Default or
Event of Default as shall be reasonably directed

<PAGE>
                                                                              77

by the Required Lenders (or, if so specified by this Agreement, all Lenders);
PROVIDED that unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable in the best interests of the
Lenders.

               9.6 NON-RELIANCE ON AGENTS AND OTHER LENDERS. Each Lender
expressly acknowledges that neither the Agents nor any of their respective
officers, directors, employees, agents, attorneys-in-fact or affiliates have
made any representations or warranties to it and that no act by any Agent
hereinafter taken, including any review of the affairs of a Loan Party or any
affiliate of a Loan Party, shall be deemed to constitute any representation or
warranty by any Agent to any Lender. Each Lender represents to the Agents that
it has, independently and without reliance upon any Agent, Co-Lead Arranger or
any other Lender, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of the
Loan Parties and their affiliates and made its own decision to make its Loans
hereunder and enter into this Agreement. Each Lender also represents that it
will, independently and without reliance upon any Agent, Co-Lead Arranger or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Agreement and the other
Loan Documents, and to make such investigation as it deems necessary to inform
itself as to the business, operations, property, financial and other condition
and creditworthiness of the Loan Parties and their affiliates. Except for
notices, reports and other documents expressly required to be furnished to the
Lenders by the Administrative Agent hereunder, the Administrative Agent shall
not have any duty or responsibility to provide any Lender with any credit or
other information concerning the business, operations, property, condition
(financial or otherwise), prospects or creditworthiness of any Loan Party or any
affiliate of a Loan Party that may come into the possession of the
Administrative Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or affiliates.

               9.7 INDEMNIFICATION. The Lenders agree to indemnify each of the
Other Representatives and the Administrative Agent in its capacity as such (to
the extent not reimbursed by Holdings or the Borrower and without limiting the
obligation of Holdings or the Borrower to do so), ratably according to their
respective Aggregate Exposure Percentages in effect on the date on which
indemnification is sought under this Section (or, if indemnification is sought
after the date upon which the Commitments shall have terminated and the Loans
shall have been paid in full, ratably in accordance with such Aggregate Exposure
Percentages immediately prior to such date), from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind whatsoever that may at any time
(whether before or after the payment of the Loans) be imposed on, incurred by or
asserted against such Other Representative or the Administrative Agent in any
way relating to or arising out of, the Commitments, this Agreement, any of the
other Loan Documents or any documents contemplated by or referred to herein or
therein or the transactions contemplated hereby or thereby or any action taken
or omitted by such Other Representative or the Administrative Agent under or in
connection with any of the foregoing; PROVIDED that no Lender shall be liable
for the payment of any portion of such liabilities, obligations, losses,

<PAGE>
                                                                              78

damages, penalties, actions, judgments, suits, costs, expenses or disbursements
that are found by a final and nonappealable decision of a court of competent
jurisdiction to have resulted from such Other Representative's or the
Administrative Agent's gross negligence or willful misconduct. The agreements in
this Section shall survive the payment of the Loans and all other amounts
payable hereunder.

               9.8 AGENT IN ITS INDIVIDUAL CAPACITY. Each of the Other
Representatives, the Administrative Agent and their respective affiliates may
make loans to, accept deposits from and generally engage in any kind of business
with any Loan Party as though such Other Representative or the Administrative
Agent was not an Other Representative or the Administrative Agent, respectively.
With respect to the Loans made or renewed by any of them and with respect to any
Letter of Credit issued or participated in by any of them, each of the Other
Representatives or the Administrative Agent shall have the same rights and
powers under this Agreement and the other Loan Documents as any Lender and may
exercise the same as though it were not an Other Representative or the
Administrative Agent, and the terms "Lender" and "Lenders" shall include each of
the Other Representative or the Administrative Agent in its individual capacity.

               9.9 SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may
resign as Administrative Agent upon 10 days' notice to the Lenders and the
Borrower. If the Administrative Agent shall resign as Administrative Agent under
this Agreement and the other Loan Documents, then the Required Lenders shall
appoint from among the Lenders a successor agent for the Lenders, which
successor agent shall (unless an Event of Default under Section 8(a) or Section
8(f) with respect to the Borrower shall have occurred and be continuing) be
subject to approval by the Borrower (which approval shall not be unreasonably
withheld or delayed), whereupon such successor agent shall succeed to the
rights, powers and duties of the Administrative Agent, and the term
"Administrative Agent" shall mean such successor agent effective upon such
appointment and approval, and the former Administrative Agent's rights, powers
and duties as Administrative Agent shall be terminated, without any other or
further act or deed on the part of such former Administrative Agent or any of
the parties to this Agreement or any holders of the Loans. If no successor agent
has accepted appointment as Administrative Agent by the date that is 10 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Lenders shall assume and perform all of the duties of the Administrative
Agent hereunder until such time, if any, as the Required Lenders appoint a
successor agent as provided for above. After any retiring Administrative Agent's
resignation as Administrative Agent, the provisions of this Section 9 shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Administrative Agent under this Agreement and the other Loan Documents.

               9.10 OTHER REPRESENTATIVES. None of the Other Representatives
shall have any duties or responsibilities hereunder in its capacity as such.

                            SECTION 10. MISCELLANEOUS
<PAGE>
                                                                              79

               10.1 AMENDMENTS AND WAIVERS. Neither this Agreement, any other
Loan Document, nor any terms hereof or thereof may be amended, supplemented or
modified except in accordance with the provisions of this Section 10.1. The
Required Lenders and each Loan Party party to the relevant Loan Document may,
or, with the written consent of the Required Lenders, the Administrative Agent
and each Loan Party party to the relevant Loan Document may, from time to time,
(a) enter into written amendments, supplements or modifications hereto and to
the other Loan Documents for the purpose of adding any provisions to this
Agreement or the other Loan Documents or changing in any manner the rights of
the Lenders or of the Loan Parties hereunder or thereunder or (b) waive, on such
terms and conditions as the Required Lenders or the Administrative Agent, as the
case may be, may specify in such instrument, any of the requirements of this
Agreement or the other Loan Documents or any Default or Event of Default and its
consequences; PROVIDED, HOWEVER, that no such waiver and no such amendment,
supplement or modification shall (i) forgive or reduce the principal amount or
extend the final scheduled date of maturity of any Loan or Reimbursement
Obligation, extend the scheduled date of any amortization payment in respect of
any Term Loan, reduce the stated rate of any interest or fee payable hereunder
or extend the scheduled date of any payment thereof, or increase the amount or
extend the expiration date of any Lender's Revolving Commitment, in each case
without the consent of each Lender directly affected thereby; (ii) eliminate or
reduce any voting rights under this Section 10.1, reduce any percentage
specified in the definition of Required Lenders, consent to the assignment or
transfer by the Borrower of any of its rights and obligations under this
Agreement and the other Loan Documents, release all or substantially all of the
Collateral or release any Subsidiary Guarantor (the release of which could
reasonably be expected to have a Material Adverse Effect) from its obligations
under the Guarantee and Collateral Agreement, in each case without the consent
of all Lenders; (iii) amend, modify or waive any condition precedent to any
extension of credit under the Revolving Facility set forth in Section 5.2
(including in connection with any waiver of an existing Default or Event of
Default) without the written consent of the Majority Facility Lenders in respect
of the Revolving Facility; (iv) amend, modify or waive any provision of Section
2.15 without the consent of each Lender; (v) reduce the amount of Net Cash
Proceeds or Excess Cash Flow required to be applied to prepay Loans under this
Agreement without the consent of the Majority Facility Lenders under each
Facility; (vi) reduce the percentage specified in the definition of Majority
Facility Lenders with respect to any Facility without the consent of all Lenders
under such Facility; (vii) amend, modify or waive any provision of Section 9
without the consent of the Administrative Agent; or (viii) amend, modify or
waive any provision of Section 3 without the consent of the Issuing Lender. Any
such waiver and any such amendment, supplement or modification shall apply
equally to each of the Lenders and shall be binding upon the Loan Parties, the
Lenders, the Administrative Agent and all future holders of the Loans. In the
case of any waiver, the Loan Parties, the Lenders and the Administrative Agent
shall be restored to their former position and rights hereunder and under the
other Loan Documents, and any Default or Event of Default waived shall be deemed
to be cured and not continuing; but no such waiver shall extend to any
subsequent or other Default or Event of Default, or impair any right consequent
thereon.

               10.2 NOTICES. All notices, requests and demands to or upon the
respective parties hereto to be effective shall be in writing (including by

PROVIDED that any notice, request or demand to or upon the Administrative Agent
or the Lenders shall not be effective until received.

               10.3 NO WAIVER; CUMULATIVE REMEDIES. No failure to exercise and
no delay in exercising, on the part of the Administrative Agent or any Lender,
any right, remedy, power or privilege hereunder or under the other Loan
Documents shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, remedy, power or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right, remedy, power or

<PAGE>
                                                                              81

privilege. The rights, remedies, powers and privileges herein provided are
cumulative and not exclusive of any rights, remedies, powers and privileges
provided by law.

               10.4 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties made hereunder, in the other Loan Documents and
in any document, certificate or statement delivered pursuant hereto or in
connection herewith shall survive the execution and delivery of this Agreement
and the making of the Loans and other extensions of credit hereunder.

               10.5 PAYMENT OF EXPENSES AND TAXES. The Borrower agrees (a) to
pay or reimburse each of the Other Representatives and the Administrative Agent
for all their respective out-of-pocket costs and expenses incurred in connection
with the syndication and financing of the Facilities and the development,
preparation and execution of, and any amendment, supplement or modification to,
this Agreement and the other Loan Documents and any other documents prepared in
connection herewith or therewith, the syndication of the Facilities and the
consummation and administration of the transactions contemplated hereby and
thereby, including the reasonable fees and disbursements of counsel to the
Administrative Agent and filing and recording fees and expenses, with statements
with respect to the foregoing to be submitted to the Borrower prior to the
Closing Date (in the case of amounts to be paid on the Closing Date) and from
time to time thereafter on a quarterly basis or such other periodic basis as the
Administrative Agent shall deem appropriate, (b) to pay or reimburse each Lender
and the Administrative Agent for all its costs and expenses incurred in
connection with the enforcement or preservation of any rights under this
Agreement, the other Loan Documents and any such other documents, including the
reasonable fees and disbursements of counsel (including the allocated fees and
expenses of in-house counsel) to each Lender and of counsel to the
Administrative Agent, (c) to pay, indemnify, and hold each Lender and the
Administrative Agent harmless from, any and all recording and filing fees and
any and all liabilities with respect to, or resulting from any delay in paying,
stamp, excise and other taxes, if any, that may be payable or determined to be
payable in connection with the execution and delivery of, or consummation or
administration of any of the transactions contemplated by, or any amendment,
supplement or modification of, or any waiver or consent under or in respect of,
this Agreement, the other Loan Documents and any such other documents, and (d)
to pay, indemnify, and hold each Lender, the Other Representatives, the
Administrative Agent and their respective officers, directors, employees,
affiliates, agents and controlling persons (each, an "INDEMNITEE") harmless from
and against any and all other liabilities, obligations, losses, damages,
penalties, actions, judgments, suits of any kind or nature whatsoever with
respect to the syndication and financing of the Facilities, and the execution,
delivery, enforcement, performance and administration of this Agreement, the
other Loan Documents and any such other documents, including any of the
foregoing relating to the use of proceeds of the Loans or the violation of,
noncompliance with or liability under, any Environmental Law applicable to the
operations of Holdings, the Borrower any of its Subsidiaries or any of the
Properties and the reasonable fees and expenses of legal counsel in connection
with claims, actions or proceedings by any Indemnitee against any Loan Party
under any Loan Document (all the foregoing in this clause (d), collectively, the
"INDEMNIFIED LIABILITIES"), PROVIDED, that the Borrower shall have no obligation
hereunder to any Indemnitee with respect to Indemnified Liabilities to the
extent such Indemnified Liabilities are found by a final and nonappealable
decision of a court of competent jurisdiction to have resulted from the gross
negligence or willful misconduct of such Indemnitee. Without limiting the
foregoing, and

<PAGE>
                                                                              82

to the extent permitted by applicable law, the Borrower agrees not to assert and
to cause its Subsidiaries not to assert, and hereby waives and agrees to cause
its Subsidiaries to so waive, all rights for contribution or any other rights of
recovery with respect to all claims, demands, penalties, fines, liabilities,
settlements, damages, costs and expenses of whatever kind or nature, under or
related to Environmental Laws, that any of them might have by statute or
otherwise against any Indemnitee. All amounts due under this Section 10.5 shall
be payable not later than 10 days after written demand therefor. Statements
payable by the Borrower pursuant to this Section 10.5 shall be submitted to
Chief Financial Officer (Telephone No. 617-367-2163) (Telecopy No.
617-367-8519), at the address of the Borrower set forth in Section 10.2, or to
such other Person or address as may be hereafter designated by the Borrower in a
written notice to the Administrative Agent. The agreements in this Section 10.5
shall survive repayment of the Loans and all other amounts payable hereunder.

               10.6 SUCCESSORS AND ASSIGNS; PARTICIPATIONS AND ASSIGNMENTS. (a)
This Agreement shall be binding upon and inure to the benefit of Holdings, the
Borrower, the Lenders, the Administrative Agent, all future holders of the Loans
and their respective permitted successors and assigns, except that the Borrower
may not assign or transfer any of its rights or obligations under this Agreement
without the prior written consent of each Lender.

               (b) Any Lender may, without the consent of the Borrower or the
Administrative Agent, in accordance with applicable law, at any time sell to one
or more banks, financial institutions or other entities (each, a "PARTICIPANT")
participating interests in any Loan owing to such Lender, any Commitment of such
Lender or any other interest of such Lender hereunder and under the other Loan
Documents. In the event of any such sale by a Lender of a participating interest
to a Participant, such Lender's obligations under this Agreement to the other
parties to this Agreement shall remain unchanged, such Lender shall remain
solely responsible for the performance thereof, such Lender shall remain the
holder of any such Loan for all purposes under this Agreement and the other Loan
Documents, and the Borrower and the Administrative Agent shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Documents. In no event shall
any Participant under any such participation have any right to approve any
amendment or waiver of any provision of any Loan Document, or any consent to any
departure by any Loan Party therefrom, except to the extent that such amendment,
waiver or consent would reduce the principal of, or interest on, the Loans or
any fees payable hereunder, or postpone the date of the final maturity of the
Loans, in each case to the extent subject to such participation. The Borrower
agrees that if amounts outstanding under this Agreement and the Loans are due or
unpaid, or shall have been declared or shall have become due and payable upon
the occurrence of an Event of Default, each Participant shall, to the maximum
extent permitted by applicable law, be deemed to have the right of setoff in
respect of its participating interest in amounts owing under this Agreement to
the same extent as if the amount of its participating interest were owing
directly to it as a Lender under this Agreement, PROVIDED that, in purchasing
such participating interest, such Participant shall be deemed to have agreed to
share with the Lenders the proceeds thereof as provided in Section 10.7(a) as
fully as if it were a Lender hereunder. The Borrower also agrees that each
Participant shall be entitled to the benefits of Sections 2.16, 2.17 and 2.18
with respect to its participation in the Commitments and the Loans outstanding
from time to time as if it was a Lender; PROVIDED that, in the case of Section
2.17, such Participant shall have

<PAGE>
                                                                              83

complied with the requirements of said Section and PROVIDED, FURTHER, that no
Participant shall be entitled to receive any greater amount pursuant to any such
Section than the transferor Lender would have been entitled to receive in
respect of the amount of the participation transferred by such transferor Lender
to such Participant had no such transfer occurred.

               (c) Any Lender (an "ASSIGNOR") may, in accordance with applicable
law, at any time and from time to time assign to any Lender or any Affiliate
thereof or a Related Fund of any Lender or, with the consent of the Borrower and
the Administrative Agent (which, in each case, shall not be unreasonably
withheld or delayed), to an additional bank, financial institution or other
entity (an "ASSIGNEE") all or any part of its rights and obligations under this
Agreement pursuant to an Assignment and Acceptance, executed by such Assignee,
such Assignor and any other Person whose consent is required pursuant to this
paragraph, and delivered to the Administrative Agent for its acceptance and
recording in the Register; PROVIDED that no such assignment to an Assignee
(other than any Lender or any affiliate thereof or any Related Fund) shall be in
an aggregate principal amount of less than $5,000,000 (other than in the case of
an assignment of all of a Lender's interests under this Agreement), unless
otherwise agreed by the Borrower and the Administrative Agent. Any such
assignment need not be ratable as among the Facilities. Upon such execution,
delivery, acceptance and recording, from and after the effective date determined
pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be
a party hereto and, to the extent provided in such Assignment and Acceptance,
have the rights and obligations of a Lender hereunder with a Commitment and/or
Loans as set forth therein, and (y) the Assignor thereunder shall, to the extent
provided in such Assignment and Acceptance, be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering
all of an Assignor's rights and obligations under this Agreement, such Assignor
shall cease to be a party hereto). Notwithstanding any provision of this Section
10.6, the consent of the Borrower shall not be required for any assignment that
occurs when an Event of Default pursuant to Section 8(f) shall have occurred and
be continuing with respect to the Borrower.

               (d) Notwithstanding anything to the contrary contained herein,
any Lender which is a bank (a "GRANTING BANK") may grant to a special purpose
funding vehicle (an "SPC"), identified as such in writing from time to time by
the Granting Bank to the Administrative Agent and the Borrower, the option to
provide to the Borrower all or any part of any Loan which such Granting Bank
would otherwise be obligated to make to the Borrower pursuant to this Agreement;
PROVIDED, THAT (i) nothing herein shall constitute a commitment by any SPC to
make any Loan, (ii) if an SPC elects not to exercise such option or otherwise
fails to provide all or any part of such Loan, the Granting Bank shall be
obligated to make such Loan pursuant to the terms hereof. The making of a Loan
by an SPC hereunder shall utilize the Commitment of the Granting Bank to the
same extent, and as if, such Loan were made by such Granting Bank. Each party
hereto hereby agrees that no SPC shall be liable for any indemnity or similar
payment obligation hereunder (all liability for which shall remain with the
Granting Bank). In furtherance of the foregoing, each party hereto agrees (which
agreement shall survive termination of this Agreement) that in the event of any
such grant by a Granting Bank to an SPC of the option to provide to the Borrower
all or any part of its Loan, (i) such Granting Bank's obligations under this
Agreement to the other parties to this Agreement shall remain unchanged and such
Granting Bank shall remain solely responsible for the performance of such
obligations under this

<PAGE>
                                                                              84

Agreement and the other Loan Documents, (ii) such Granting Bank shall remain the
holder of such Loan for all purposes under this Agreement and the other Loan
Documents and nothing contained in this Section 10.6(d) is intended to excuse
the Granting Bank from the full performance of its obligations hereunder and
thereunder or otherwise diminish the duties and liabilities of the Granting Bank
under this Agreement or the other Loan Documents (other than it being understood
that any payment obligation on the part of such Granting Bank to make a Loan
hereunder shall, if such Loan is made by any SPC, be deemed to have been
satisfied upon the making of such Loan by such SPC), (iii) the Borrower and the
Administrative Agent shall continue to deal solely and directly with such
Granting Bank in connection with such Granting Bank's rights and obligations
under this Agreement and the other Loan Documents, (iv) in no event shall any
SPC have any right to approve any amendment or waiver of any provision of any
Loan Document, or any consent to any departure by any Loan Party therefrom, or
be included in any determination of the Required Lenders or the Majority
Facility Lenders hereunder for any purpose, (v) prior to the date that is one
year and one day after the payment in full of all outstanding commercial paper
or other senior Indebtedness of any SPC, it will not institute against, or join
any other Person in instituting against, such SPC any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings under the
laws of the United States or any State thereof. In addition, notwithstanding
anything to the contrary contained in this Section 10.6(d), any SPC may (X) with
notice to, but without prior written consent of, the Borrower and the
Administrative Agent (subject, however, to the approval of the financial
institution as set forth below), assign all or a portion of its interests in any
Loan to the Granting Bank or to a financial institution (previously approved in
writing by the Borrower and the Administrative Agent) providing liquidity and/or
credit support to or for the account of such SPC to support the funding or
maintenance of the Loans and (Y) subject to Section 10.15 hereof, disclose on a
confidential basis any non-public information relating to its Loans to any
rating agency as specifically provided for in Section 10.15 hereof. This Section
10.6 may not be amended without the prior written consent of the SPC, the
Borrower and the Administrative Agent.

               (e) The Administrative Agent shall, on behalf of the Borrower,
maintain at its address referred to in Section 10.2 a copy of each Assignment
and Acceptance delivered to it and a register (the "REGISTER") for the
recordation of the names and addresses of the Lenders and the Commitment of, and
the principal amount of the Loans owing to, each Lender from time to time. The
entries in the Register shall be conclusive, in the absence of manifest error,
and the Borrower, each other Loan Party, the Administrative Agent and the
Lenders shall treat each Person whose name is recorded in the Register as the
owner of the Loans and any Notes evidencing the Loans recorded therein for all
purposes of this Agreement. Any assignment of any Loan, whether or not evidenced
by a Note, shall be effective only upon appropriate entries with respect thereto
being made in the Register (and each Note, if any, shall expressly so provide).
Any assignment or transfer of all or part of a Loan evidenced by a Note shall be
registered on the Register only upon surrender for registration of assignment or
transfer of the Note evidencing such Loan, accompanied by a duly executed
Assignment and Acceptance, and thereupon one or more new Notes, upon request,
shall be issued to the designated Assignee.

               (f) Upon its receipt of an Assignment and Acceptance executed by
an Assignor, an Assignee and any other Person whose consent is required by
Section 10.6(c), together with payment to the Administrative Agent of a
registration and processing fee of $4,000, the

<PAGE>
                                                                              85

Administrative Agent shall (i) promptly accept such Assignment and Acceptance
and (ii) record the information contained therein in the Register on the
effective date determined pursuant thereto.

               (g) For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this Section 10.6 concerning assignments of
Loans and Notes, if any, relate only to absolute assignments and that such
provisions do not prohibit assignments creating security interests, including
any pledge or assignment by a Lender of any Loan or Note, if any, to any Federal
Reserve Bank or trustee (or similar entity) of a Lender in accordance with
applicable law.

               (h) The Borrower, upon receipt of written notice from the
relevant Lender, agrees to issue Notes to any Lender requiring Notes to
facilitate transactions of the type described in paragraph (g) above.

               10.7 ADJUSTMENTS; SET-OFF. (a) Except to the extent that this
Agreement expressly provides for payments to be allocated to a particular Lender
or to the Lenders under a particular Facility, if any Lender (a "BENEFITTED
LENDER") shall, at any time after the Loans and other amounts payable hereunder
shall immediately become due and payable pursuant to Section 8, receive any
payment of all or part of the Obligations owing to it, or receive any collateral
in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant
to events or proceedings of the nature referred to in Section 8(f), or
otherwise), in a greater proportion than any such payment to or collateral
received by any other Lender, if any, in respect of the Obligations owing to
such other Lender, such Benefitted Lender shall purchase for cash from the other
Lenders a participating interest in such portion of the Obligations owing to
each such other Lender, or shall provide such other Lenders with the benefits of
any such collateral, as shall be necessary to cause such Benefitted Lender to
share the excess payment or benefits of such collateral ratably with each of the
Lenders; PROVIDED, HOWEVER, that if all or any portion of such excess payment or
benefits is thereafter recovered from such Benefitted Lender, such purchase
shall be rescinded, and the purchase price and benefits returned, to the extent
of such recovery, but without interest.

               (b) In addition to any rights and remedies of the Lenders
provided by law, each Lender shall have the right, without prior notice to
Holdings or the Borrower, any such notice being expressly waived by Holdings and
the Borrower to the extent permitted by applicable law, upon any amount becoming
due and payable by Holdings or the Borrower hereunder (whether at the stated
maturity, by acceleration or otherwise), to set off and appropriate and apply
against such amount any and all deposits (general or special, time or demand,
provisional or final), in any currency, and any other credits, indebtedness or
claims, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by such Lender or
any branch or agency thereof to or for the credit or the account of Holdings or
the Borrower, as the case may be. Each Lender agrees promptly to notify the
Borrower and the Administrative Agent after any such setoff and application made
by such Lender, PROVIDED that the failure to give such notice shall not affect
the validity of such setoff and application.

               10.8 COUNTERPARTS. This Agreement may be executed by one or more
of the parties to this Agreement on any number of separate counterparts, and all
of said counterparts taken together shall be deemed to constitute one and the
same instrument. Delivery of an

<PAGE>
                                                                              86

executed signature page of this Agreement by facsimile transmission shall be
effective as delivery of a manually executed counterpart hereof. A set of the
copies of this Agreement signed by all the parties shall be lodged with the
Borrower and the Administrative Agent.

               10.9 SEVERABILITY. Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

               10.10 INTEGRATION. This Agreement and the other Loan Documents
represent the agreement of Holdings, the Borrower, the Administrative Agent and
the Lenders with respect to the subject matter hereof, and there are no
promises, undertakings, representations or warranties by the Administrative
Agent or any Lender relative to subject matter hereof not expressly set forth or
referred to herein or in the other Loan Documents.

               10.11  GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

               10.12  SUBMISSION TO JURISDICTION; WAIVERS.  Each of Holdings and
the Borrower hereby irrevocably and unconditionally:

               (a) submits for itself and its property in any legal action or
        proceeding relating to this Agreement and the other Loan Documents to
        which it is a party, or for recognition and enforcement of any judgment
        in respect thereof, to the non-exclusive general jurisdiction of the
        courts of the State of New York, the courts of the United States for the
        Southern District of New York, and appellate courts from any thereof;

               (b) consents that any such action or proceeding may be brought in
        such courts and waives any objection that it may now or hereafter have
        to the venue of any such action or proceeding in any such court or that
        such action or proceeding was brought in an inconvenient court and
        agrees not to plead or claim the same;

               (c) agrees that service of process in any such action or
        proceeding may be effected by mailing a copy thereof by registered or
        certified mail (or any substantially similar form of mail), postage
        prepaid, to Holdings or the Borrower, as the case may be at its address
        set forth in Section 10.2 or at such other address of which the
        Administrative Agent shall have been notified pursuant thereto;

               (d) agrees that nothing herein shall affect the right to effect
        service of process in any other manner permitted by law or shall limit
        the right to sue in any other jurisdiction; and
<PAGE>
                                                                              87

               (e) waives, to the maximum extent not prohibited by law, any
        right it may have to claim or recover in any legal action or proceeding
        referred to in this Section any special, exemplary, punitive or
        consequential damages.

               10.13  ACKNOWLEDGMENTS.  Each of Holdings and the Borrower hereby
acknowledges that:

               (a) it has been advised by counsel in the negotiation, execution
        and delivery of this Agreement and the other Loan Documents;

               (b) neither the Administrative Agent nor any Lender has any
        fiduciary relationship with or duty to Holdings or the Borrower arising
        out of or in connection with this Agreement or any of the other Loan
        Documents, and the relationship between Administrative Agent and
        Lenders, on one hand, and Holdings and the Borrower, on the other hand,
        in connection herewith or therewith is solely that of debtor and
        creditor; and

               (c) no joint venture is created hereby or by the other Loan
        Documents or otherwise exists by virtue of the transactions contemplated
        hereby among the Lenders or among Holdings, the Borrower and the
        Lenders.

               10.14 RELEASES OF GUARANTEES AND LIENS. (a) Notwithstanding
anything to the contrary contained herein or in any other Loan Document, the
Administrative Agent is hereby irrevocably authorized by each Lender (without
requirement of notice to or consent of any Lender except as expressly required
by Section 10.1) to take any action requested by the Borrower having the effect
of releasing any Collateral or guarantee obligations (i) to the extent necessary
to permit consummation of any transaction not prohibited by any Loan Document or
that has been consented to in accordance with Section 10.1 or (ii) under the
circumstances described in paragraph (b) below.

               (b) At such time as the Loans, the Reimbursement Obligations and
the other obligations under the Loan Documents (other than obligations under or
in respect of Hedge Agreements) shall have been paid in full, the Commitments
have been terminated and no Letters of Credit shall be outstanding, the
Collateral shall be released from the Liens created by the Security Documents,
and the Security Documents and all obligations (other than those expressly
stated to survive such termination) of the Administrative Agent and each Loan
Party under the Security Documents shall terminate, all without delivery of any
instrument or performance of any act by any Person and at such time, the
Administrative Agent agrees to promptly take such action and execute and deliver
such instruments and documents as shall be necessary to release the Liens and
security interests created by the Security Documents, including, without
limitation, any Uniform Commercial Code release or termination statements.

               10.15 CONFIDENTIALITY. Each of the Administrative Agent and each
Lender agrees to keep confidential all non-public information provided to it by
any Loan Party pursuant to this Agreement that is designated by such Loan Party
as confidential; PROVIDED that nothing herein shall prevent the Administrative
Agent or any Lender from disclosing any such information (a) to the
Administrative Agent, any other Lender or any affiliate of any Lender, (b) to
any Transferee

<PAGE>

qualified and is in good standing as a foreign corporation authorized to do
business in each jurisdiction in which such qualification is required, except

is bound, except for any such defaults in (ii) as would not, singly or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

and each of its Subsidiaries, taken as a whole, in each case free and clear of
all Liens, except for Liens under the Senior Credit Facilities or such as do
not, singly or in the aggregate, have a Material Adverse Effect. Any real
property and buildings held under lease by Concentra or any of its Subsidiaries
are held by Concentra or such Subsidiary under valid, subsisting and enforceable

Practices Act or the rules and regulations promulgated thereunder, which

contamination, or, to the Concentra's knowledge, any circumstances forming the
basis of any violation, or alleged violation, of any Environmental Law
(collectively, "ENVIRONMENTAL CLAIMS"), and (C) there are no past or present
actions, activities, circumstances, conditions, events or incidents that could

Effect.

                  Section 3.9 NO BROKERS. There are no contracts, agreements or
understandings between Concentra or any of its Subsidiaries and any person that

with the issuance, purchase and sale of the Units.

                  Section 3.10 LABOR MATTERS. Concentra has no knowledge of any
actionable violation by Concentra or any of its Subsidiaries of any Federal,

existing with respect to the employees of Concentra or any of its Subsidiaries

Environmental Laws, laws relating to the provisions of occupational healthcare
services, medical review services and the operation of managed care provider
networks as are necessary to own, lease, license and operate its properties and

make any such filing or notice would not, singly or in the aggregate, have a
Material Adverse Effect. Each such permit is valid and in full force and effect

and conditions of its permits and with the rules and regulations of the
authorities and governing bodies having jurisdiction with respect thereto; no

notice or lapse of time or both, would result in any other impairment of the
rights of the holder of any such permit; and such permits contain no
restrictions that are unduly burdensome to Concentra and its Subsidiaries,
except, in each case, where such failure to be valid and in full force and
effect or to be in compliance, the occurrence of any such event or the presence

Adverse Effect.

singly or in the aggregate, have a Material Adverse Effect: (i) Concentra and
its Subsidiaries own or possess, free and clear of all Liens (other than Liens

effect to the offering of the Units as contemplated hereby and the consummation
of the Merger and the transactions contemplated thereby, (i) the present fair
salable value of Concentra's and each of its Subsidiaries' assets shall be more
than the amount that will be required to pay its debts (including contingent and

party does not and will not (i) violate, if such Buyer is a corporation, the
certificate of incorporation or bylaws of such Buyer, if such Buyer is a limited
partnership, the certificate of limited partnership or agreement of limited
partnership of such Buyer, or, if such Buyer is a limited liability company, the
certificate of formation or limited liability company agreement of such Buyer,
(ii) violate any law, rule, regulation, judgment, injunction, order or decree
applicable to or binding upon such Buyer, (iii) require any consent or other
action by any person under, constitute a default under (with due notice or lapse
of time or both), or give rise to any right of termination, cancellation or
acceleration of any right or obligation of such Buyer or to a loss of any
benefit to which such Buyer is entitled under any provision of any agreement or
other instrument binding upon such Buyer or any of its assets or properties or
(iv) result in the creation or imposition of any material Lien on any property
or asset of such Buyer.

                  Section 4.5 PURCHASE FOR INVESTMENT. Such Buyer is purchasing
its Units for investment for its own account and not with a view to, or for sale
in connection with, any distribution thereof.

                  Section 4.6 PRIVATE PLACEMENT. (a) Such Buyer's financial
situation is such that such Buyer can afford to bear the economic risk of
holding its Units for an indefinite period of time, and such Buyer can afford to
suffer the complete loss of the investment in its Units.

                  (b) Such Buyer's knowledge and experience in financial and
business matters are such that it is capable of evaluating the merits and risks
of the investment in its Units or such Buyer has been advised by a
representative possessing such knowledge and experience.

                  (c) Such Buyer understands that the Units acquired hereunder
is a speculative investment which involves a high degree of risk of loss of the
entire investment therein, that there will be substantial restrictions on the
transferability of the Units and that for an indefinite period following the
date hereof there will be no public market for the Units and that, accordingly,
it may not be possible for such Buyer to sell the Units in case of emergency or
otherwise.

                  (d) Such Buyer and its representatives, including, to the
extent it deems appropriate, its professional, financial, tax and other
advisors, have reviewed all documents provided to them in connection with the
investment in the Units, and such Buyer understands and is aware of the risks
related to such investment.

                  (e) Such Buyer and its representatives have been given the
opportunity to examine all documents and to ask questions of, and to receive
answers from, Concentra and its respective representatives concerning the terms
and conditions of the acquisition of the Units and related matters and to obtain
all additional information which such Buyer or its representatives deem
necessary.

                  (f) Except as otherwise disclosed to Concentra, such Buyer is
an "ACCREDITED INVESTOR" as such term is defined in Regulation D under the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder.

                  Section 4.7 LITIGATION. There is no action, suit,
investigation or proceeding pending against, or to the knowledge of such Buyer
threatened against or affecting, such Buyer before any court or arbitrator or
any governmental body, agency or official which would be reasonably likely to
have a Material Adverse Effect.

                  Section 4.8 NO BROKERS. There are no contracts, agreements or
understandings between such Buyer and any person that would give rise to a valid
claim against Concentra, any of its Subsidiaries or any Buyer for a brokerage
commission, finder's fee or like payment in connection with the issuance,
purchase and sale of the Units.

                        COVENANTS OF CONCENTRA AND BUYERS

                  Section 5.1 FURTHER ASSURANCES. Concentra and each Buyer agree

<PAGE>

                  (a) On the Closing Date, the Buyers shall have received an
opinion, dated the Closing Date, of Richard A. Parr II, general counsel for
Concentra, substantially to the effect that:

                           a. Each of the Operative Agreements to which
         Concentra is a party has been duly authorized, executed and delivered
         by Concentra.

                           b. The execution, delivery and performance by
         Concentra of each Operative Document, the issuance and sale of the
         Units, including the Debentures and the Warrants, as contemplated by
         this Agreement and the consummation of the transactions contemplated by
         this Agreement and each other Operative Document will not (i) except to
         the extent such has been obtained, require any consent, approval,
         authorization or other order of, or qualification with, any court or
         governmental body or agency (except such as may be required under the
         securities or Blue Sky laws of the various states and except, in the
         case of the Registration Rights Agreement, such as may be required
         under the Securities Act), (ii) conflict with or constitute a breach of
         any of the terms or provisions of, or a default under (A) the
         organization documents or by-laws or other organizational documents of
         Concentra or any of its Subsidiaries or (B) any indenture, loan
         agreement, mortgage, lease or other agreement or instrument that is
         material to Concentra or any of its Subsidiaries, taken as a whole, to
         which Concentra or any of its Subsidiaries is a party or by which
         Concentra or any of its Subsidiaries or their respective property is
         bound, (iii) to such counsel's knowledge after due inquiry, violate or
         conflict with any applicable law or any rule, regulation, judgment,
         order or decree of any court or any governmental body or agency having
         jurisdiction over Concentra or any of its Subsidiaries or their
         respective property, (iv) result in the imposition or creation of (or
         the obligation to create or impose) a Lien under, any agreement or
         instrument to which Concentra or any of its Subsidiaries is a party or
         by which Concentra or any of its Subsidiaries or their respective
         property is bound, or (v) result in the termination or revocation of
         any permit of Concentra or any of its Subsidiaries or result in any
         other impairment of the rights of the holder of any such permit, except
         in the case of clauses (i), (ii) (B), (iv) and (v), as would not,
         singly or in the aggregate, have a Material Adverse Effect.

                           c. No injunction, restraining order or other order or
         relief of any nature by a federal or state court or other tribunal of
         competent jurisdiction has been issued with respect to Concentra or any
         of its Subsidiaries which would prevent or suspend the issuance or sale
         of the Units, including the Debentures or the Warrants, or the
         consummation of any transaction contemplated by the Operative
         Agreements.

                           d. To the best of counsel's knowledge after due
         inquiry, there is no legal or governmental proceeding pending or
         threatened to which Concentra or any of its Subsidiaries is bound or
         could reasonably be expected to be a party or to which any of their
         respective property is or could reasonably be expected to be subject,
         except for

                                       16

<PAGE>

         any such proceedings as would not, singly or in the aggregate, be
         reasonably expected to have a Material Adverse Effect.

                           e. Neither Concentra nor any of its Subsidiaries is
         in violation of its organizational documents or bylaws or other
         organizational documents and, to the knowledge of such counsel after
         due inquiry, neither Concentra nor any of its Subsidiaries (a) is in
         default in the performance of any obligation, agreement, covenant or
         condition contained in any indenture, loan agreement, mortgage, lease
         or other agreement or instrument that is material to Concentra or any
         of its Subsidiaries, taken as a whole, to which Concentra or any of its
         Subsidiaries is a party or by which Concentra or any of its
         Subsidiaries or their respective property is bound, or (b) is in
         violation of any applicable statute, rule or regulation (including,
         without limitation, any Environmental Law, any Relevant Healthcare Laws
         or any provision of ERISA or the rules and regulations promulgated
         thereunder) or any order, writ or decree of any court or governmental
         agency or body having jurisdiction over Concentra or any of its
         Subsidiaries or their respective property, except in the case of (a)
         and (b), for such violations which, singly or in the aggregate, would
         not have a Material Adverse Effect.

                  (b) On the Closing Date, the Buyers shall have received an
opinion, dated the Closing Date, of Reboul, MacMurray, Hewitt, Maynard &
Kristol, special counsel to Concentra substantially to the effect that:

                           a. All of the outstanding capital stock of Concentra
         issued after the Merger is consummated (i) has been duly authorized and
         validly issued and (ii) is fully paid, nonassessable and, to such
         counsel's knowledge after due inquiry, not subject to preemptive or
         similar rights, except as provided in the Stockholders Agreement, dated
         as of August 17, 1999, by and among Concentra and the several
         purchasers name in Schedule I thereto.

                           b.  Assuming due authorization by Concentra, this
Agreement has been duly executed and delivered by Concentra.

                           c. Assuming the due authorization of the Indenture by
         Concentra and the Trustee, each of the Operative Agreements has been
         duly authorized, executed and delivered by Concentra and, assuming the
         due execution and delivery by the Buyers, is a valid and binding
         agreement of Concentra, enforceable against Concentra in accordance
         with its terms, except (i) as the enforceability thereof may be limited
         by bankruptcy, fraudulent conveyance, insolvency, reorganization,
         moratorium or other similar laws affecting creditors' rights generally,
         (ii) for general principles of equity (regardless of whether
         enforcement is brought in a proceeding at law or in equity), (iii)
         limitations of applicable law regarding the enforceability of any
         rights to contribution or indemnification and (iv) the waiver as to
         stay, extension or usury laws may not be enforceable.

                                       17

<PAGE>



                           d. When executed and authenticated in accordance with
         the provisions of the Indenture and delivered to and paid for by the
         Buyers in accordance with the terms of this Agreement, the Debentures
         will be valid and binding obligations of Concentra, entitled to the
         benefits of the Indenture and enforceable against Concentra in
         accordance with their terms, except (i) as the enforceability thereof
         may be limited by bankruptcy, fraudulent conveyance, insolvency,
         reorganization, moratorium or other similar laws affecting creditors'
         rights generally, (ii) for general principles of equity (regardless of
         whether enforcement is brought in a proceeding at law or in equity) and
         (iii) the waiver as to stay, extension or usury laws may not be
         enforceable.

                           e. The Warrants are convertible into Warrant Shares
         in accordance with their terms and the Warrant Shares have been duly
         authorized and reserved for issuance upon such conversion and, when
         issued upon such conversion, will be validly issued, fully paid and
         nonassessable.

                           f. Each of Concentra and its Subsidiaries is not an
         "investment company," as such term is defined in the Investment Company
         Act of 1940, as amended.

                           g. The Indenture complies as to form in all material
         respects with the requirements of the TIA, and the rules and
         regulations of the Commission applicable to an indenture which is
         qualified thereunder.

                            h. No registration under the Securities Act of the
         Units, including the Debentures and the Warrants, or qualification of
         the Indenture under the TIA is required for the sale of the Units,
         including the Debentures and the Warrants, to the Buyers as
         contemplated by this Agreement, assuming (i) the accuracy of, and
         compliance with, the Buyers' representations and agreements contained
         in Article 4 of this Agreement and (ii) the accuracy of the
         representations and agreements of Concentra set forth in this Agreement
         and (iii) that the offer, sale and delivery of the Units, including the
         Debentures and the Warrants have been made as contemplated by this
         Agreement.

                           i. To such counsel's knowledge after due inquiry, no
         action has been taken and no law, statute, rule or regulation or order
         has been enacted, adopted or issued by any governmental agency or body
         which prevents the execution, delivery or performance of any of the
         Operative Agreements, the consummation of any of the transactions
         contemplated thereunder or the issuance of the Units, including the
         Debentures or the Warrants, or suspends the sale of the Units,
         including the Debentures or the Warrants.

                  (c) Concentra shall have executed and delivered the Operative
Agreements.

                  (d) Concentra and the Trustee shall have executed and
delivered the Indenture.

                                       18
<PAGE>

                  (e) On the Closing Date, the Buyers shall have received a
solvency opinion from Valuation Research, dated the Closing Date, as to the
solvency of Concentra (on a consolidated basis) after giving effect to the
Merger, the transactions contemplated thereby and the financings and
transactions contemplated herein in form and substance reasonably satisfactory
to the Buyers.

                  (f) The Senior Credit Facilities shall have been executed by
the parties thereto and, on the Closing Date, the closing under the Senior
Credit Facilities (including, without limitation, the borrowing of all term
loans thereunder) shall have been consummated simultaneously with the
consummation of the offering of the Units.

                  (g) All of the conditions precedent to the Merger Agreement
shall have been satisfied or waived and the Merger shall have been consummated.

                  Section 6.2 CONDITIONS TO OBLIGATION OF CONCENTRA. The
obligation of Concentra to consummate the transactions contemplated hereby is
subject to the satisfaction of the following further conditions:

                  (a) Each Buyer shall have performed in all material respects
         all of its obligations hereunder required to be performed by it at or
         prior to the Closing Date.

                  (b) Each Buyer shall have executed and delivered the
Registration Rights Agreement and the Warrant Agreement.

                                    ARTICLE 7

           SURVIVAL OF REPRESENTATIONS AND WARRANTIES: INDEMNIFICATION

                  Section 7.1 SURVIVAL. Except for the representations and
warranties contained in Sections 3.1 and 3.3, which shall survive indefinitely,
the representations and warranties of the parties hereto contained in this
Agreement shall survive the Closing until twelve months after the Closing Date,
and thereafter shall terminate and be of no further force or effect.

                  Section 7.2 INDEMNIFICATION. (a) Concentra hereby indemnifies
each Buyer and its affiliates, limited partners, general partners, directors,
officers, trustees and employees against and agrees to hold each of them
harmless from any and all damage, loss, liability and expense (including,
without limitation, reasonable expenses of investigation and reasonable
attorneys' fees and expenses in connection with any action, suit or proceeding)
("DAMAGES") incurred or suffered by any such party arising out of any
misrepresentation or breach of warranty, covenant or agreement made or to be
performed by Concentra pursuant to this Agreement; PROVIDED that with respect to
any Buyer, (i) Concentra shall not be liable under this Section 7.2(a) unless
the aggregate amount of Damages with respect to all matters referred to in this
Section 7.2(a) for

                                       19

<PAGE>

which such Buyer has sought indemnification exceeds $100,000 and then only to
the extent of such excess and (ii) the indemnifying parties' aggregate maximum
liability under this Section 7.2(a) to any Buyer shall not exceed the amount of
the Aggregate Purchase Price paid by such Buyer to Concentra.

                  (b) Each Buyer hereby indemnifies, severally and not jointly,
Concentra and its affiliates, limited partners, general partners, directors,
officers and employees against and agrees to hold each of them harmless from any
and all Damages incurred or suffered by any such party arising out of any
misrepresentation or breach of warranty, covenant or agreement made or to be
performed by such Buyer pursuant to this Agreement; PROVIDED that (i) such Buyer
shall not be liable under this Section 7.2(b) unless the aggregate amount of
Damages with respect to all matters referred to in this Section 7.2(b) exceeds
$100,000 and then only to the extent of such excess and (ii) such Buyer's
maximum liability under this Section 7.2(b) shall not exceed the amount of
Aggregate Purchase Price paid by such Buyer to Concentra.

                  (c) Each Buyer acknowledges that because of the $100,000
threshold established in Section 7.2(a), one or more Buyers may be compensated
under such section while another Buyer or Buyers is not so compensated because
of the operation of such $100,000 threshold. In order to correct the inequities
which might otherwise result, each Buyer agrees to contribute such amounts to
such other Buyers as may be necessary so that, after giving effect to all such
contributions, each Buyer has received (i) the amount it would have received had
there been no $100,000 threshold in Section 7.2(a), (ii) multiplied by a
fraction, the numerator of which is the aggregate of all indemnity payments
actually paid under Section 7.2(a) and the denominator of which is the aggregate
of all indemnity payments actually paid under Section 7.2(a) plus all indemnity
amounts actually offset against the $100,000 threshold.

                  Similarly, each Buyer acknowledges that because of the
$100,000 threshold in Section 7.2(b), one or more Buyers could be required to
make indemnity payments under such section while another Buyer or Buyers is not
so required because of the operation of such $100,000 threshold. Each Buyer
agrees to contribute such amounts to such other Buyers as may be necessary so
that, after giving effect to all such contributions, each Buyer has paid an
indemnity amount equal to (i) the amount it would have paid had there been no
$100,000 threshold in Section 7.2(b), (ii) multiplied by a fraction, the
numerator of which is the aggregate of all indemnity payments actually paid
under Section 7.2(b) and the denominator of which is the aggregate of all
indemnity payments actually paid under Section 7.2(b) plus all indemnity amounts
actually offset against the $100,000 threshold.

                  Concentra shall provide WCAS Capital Partners III, L.P. ("WCAS
CP III") with information relating to any amounts paid or offset under Sections
7.2(a) or 7.2(b), within 30 days of the date of each such payment or offset.
WCAS will provide such information to its independent accountants who will, no
later than February 28 (or 29) of each year determine the contribution amounts,
contribution payors and contribution payees for the previous calendar year and
provide notice to each Buyer as to its determinations under this Section 7.2(c).
Those Buyers

                                       20

<PAGE>

who are required to make contributions shall pay such amounts to WCAS CP III's
independent accountants within 30 days of the receipt of such notice. Such
accountants will in turn, make payments to the contribution payees in accordance
with the determinations set forth in the notice. Buyers agree that the
determination of WCAS CP III's independent accounts as to all matters relating
to this Section 7.2(c) shall be conclusive and binding on all parties, absent
manifest error.

                                    ARTICLE 8

                         TAG-ALONG AND DRAG-ALONG RIGHTS

                  SECTION 8.1 TAG-ALONG RIGHTS.

                  (a) Until the earlier of (1) the second anniversary of the
date the Debentures are first issued and (2) the date the Buyers sell at least
50% of the outstanding Debentures, with respect to any proposed Transfer by WCAS
CP III (the "SELLING DEBENTUREHOLDER") of a majority of the Debentures held by
WCAS CP III to any Person (including an underwriter or an initial purchaser in
connection with an offering pursuant to Rule 144A or Regulation S of the
Securities Act or in a Public Offering pursuant to a bona fide sale to the
public) (any such transaction, a "PROPOSED SALE"), each Buyer (other than WCAS
CP III) (a "TAGGING DEBENTUREHOLDER") will have the right to require the Selling
Debentureholder to include in such Proposed Sale a face amount of the Debentures
equal to up to the product (rounded up to the nearest whole number) of (i) the
quotient determined by dividing (A) the aggregate face amount of the Debentures
owned by such Tagging Debentureholders by (B) the aggregate face amount of the
Debentures owned by WCAS CP III and the Tagging Debentureholders and (ii) the
total face amount of the Debentures proposed to be directly or indirectly
Transferred to the transferee or acquiring Person in the Proposed Sale (a
"PROPOSED TRANSFEREE"), at the same price per face amount of the Debentures and
upon the same terms and conditions (including, without limitation, time of
payment, form of consideration, inclusion of Warrants and adjustments to
purchase price) as the Selling Debentureholder; PROVIDED that in order to be
entitled to exercise its right to sell Debentures to the Proposed Transferee
pursuant to this Section 8.1(a), each Tagging Debentureholder (x) shall agree to
the same covenants with respect to such Tagging Debentureholders, as
appropriate, as the Selling Debentureholder agrees to in connection with the
Proposed Sale; PROVIDED, however, that the aggregate amount of liability of such
Tagging Debentureholder with respect to such covenants shall not exceed the
proceeds to such Tagging Debentureholder in connection with the Proposed Sale,
and (y) shall make such representations and warranties concerning its title to
the Debentures (and Warrants, if applicable) to be sold in connection with the
Proposed Sale and its authority to enter into and consummate the Proposed Sale
as the Selling Debentureholder makes, but shall not be required to make any
other representations and warranties or indemnities other than with respect to
its own representations and warranties.

                  (b) Each Tagging Debentureholder will be responsible for
funding its proportionate share of any escrow arrangements in connection with
the Proposed Sale and for its proportionate share of any withdrawals therefrom,
including without limitation any such

                                       21

<PAGE>


withdrawals that are made with respect to claims arising out of agreements,
covenants, representations, warranties or other provisions relating the Proposed
Sale that were made by the Tagging Debentureholder.

                  (c) Each Tagging Debentureholder will be responsible for its
proportionate share of the reasonable fees, discounts, commissions and other
out-of-pocket expenses (collectively, "COSTS") of the Proposed Sale to the
extent not paid or reimbursed by Concentra, the Proposed Transferee or another
Person (other than the Selling Debentureholder); PROVIDED that the Proposed Sale
is consummated and the liability for such Costs shall not exceed the total
purchase price received by such Tagging Debentureholder for such Debentures (and
Warrants, if applicable). The Selling Debentureholder shall be entitled to
estimate the Tagging Debentureholders' proportionate share of such Costs and to
withhold such amounts from payments to be made to the Tagging Debentureholder at
the time of closing of such Proposed Sale; PROVIDED that (i) such estimate shall
not preclude the Selling Debentureholder from recovering additional amounts from
the Tagging Debentureholder in respect of such Tagging Debentureholder's
proportionate share of such Costs and (ii) the Selling Debentureholder shall
reimburse the Tagging Debentureholder to the extent actual amounts are
ultimately less than the estimated amounts or any such amounts are paid by the
Company, the Proposed Transferee or another Person (other than the Selling
Debentureholder).

                  (d) The Selling Debentureholder will give notice to Concentra
of each Proposed Sale not more than five days after such Selling Debentureholder
has determined to effect a Proposed Sale, setting forth the face amount of
Debentures (and Warrants, if applicable) proposed to be so Transferred, the
manner in which the Proposed Sale will be effected, the name and address of the
Proposed Transferee (if applicable), the proposed amount and form of
consideration (and if such consideration consists in part or in whole of
property other than cash, the Selling Debentureholder will provide such
information, to the extent reasonably available to the Selling Debentureholder,
relating to such non-cash consideration as each of the Tagging Debentureholders
may reasonably request in order to evaluate such non-cash consideration) and
other terms and conditions of the Proposed Sale. If any holders of the
Debentures are given an option as to the form and amount of consideration to be
received, all holders of the Debentures shall be given the same option. In the
event that any of the terms and/or conditions set forth in the notice are
thereafter amended in any respect, the Selling Debentureholder shall also give
written notice of the amended terms and conditions of the Proposed Sale to
Concentra, and each Tagging Debentureholder shall be permitted to cancel its
exercise of its rights under this Section 8.1 upon delivery of written notice to
Concentra to such effect and shall be released from its obligation hereunder.
Upon its receipt of any such notice or amended notice, Concentra shall promptly,
but in all events within three (3) Business Days of its receipt thereof, forward
copies thereof to each of the Tagging Debentureholders. The Selling
Debentureholder will deliver or cause to be delivered to each Tagging
Debentureholder copies of all transaction documents relating to the Proposed
Sale promptly as the same become available. The tag-along rights provided by
this Section 8.1 must be exercised by the Tagging Debentureholders within 10
Business Days following receipt of the notice required by the preceding sentence
by delivery of a

                                       22
<PAGE>


written notice to the Selling Debentureholder indicating its desire to exercise
its rights and specifying the face amount of the Debentures it desires to sell
(the "TAG-ALONG NOTICE"). The Tagging Debentureholders will be entitled under
this Section 8.1 to Transfer to the Proposed Transferee the face amount of the
Debentures calculated in accordance with Section 8.1(a).

                  (e) Any Tagging Debentureholder participating in the Proposed
Sale shall deliver to Concentra, as agent for such Tagging Debentureholder, for
transfer to the Proposed Transferee one or more Debentures (and Warrants, if
applicable), properly endorsed for transfer and with all transfer taxes paid and
stamps affixed, which represent the face amount of the Debentures (and Warrants,
if applicable) that such Tagging Debentureholder elects to dispose of pursuant
to paragraph (d) above. The consummation of such proposed disposition shall be
subject to the sole discretion of the Selling Debentureholder, who shall have no
liability or obligation whatsoever to any Tagging Debentureholder participating
therein other than to obtain for such Tagging Debentureholder the same terms and
conditions as those of the Selling Debentureholder. Upon the consummation of any
such sale, Concentra (i) shall transfer to the Proposed Transferee a Debenture
or Debentures representing the face amount of the Debentures to be disposed of
by any Tagging Debentureholders (and Warrants, if applicable) and (ii) shall
promptly thereafter remit to each Tagging Debentureholder (i) that portion of
the proceeds of the disposition to which such Tagging Debentureholder is
entitled by reason of such participation and (ii) Debentures or Warrants, as the
case may be, representing any balance of face amount of the Debentures or any
number of Warrants that were not so disposed of (or all of the Debentures and
Warrants, in the event the proposed disposition is not consummated).

                  (f) If any Tagging Debentureholder exercises its rights under
this Section 8.1, the closing of the purchase of the Debentures (and Warrants,
if applicable) with respect to which such rights have been exercised will take
place concurrently with the closing of the sale of the Selling Debentureholder's
Debentures (and Warrants, if applicable) to the Proposed Transferee. If by the
end of ninety (90) days following the date of delivery of the notice of the
Proposed Sale provided by Concentra pursuant to Section 8.1(d), the Selling
Debentureholder and the Proposed Transferee have not completed the Proposed
Sale, each Tagging Debentureholder shall be released from its obligations under
this Section 8.1, and the Tag-Along Notices shall be null and void, and it shall
be necessary for the terms of this Section 8.1 to be separately complied with in
order to consummate such Proposed Sale pursuant to this Section 8.1.

                         SECTION 8.2. DRAG-ALONG RIGHTS.

                  (a) Until the earlier of (1) the second anniversary of the
date the Debentures are first issued and (2) the date the Buyers sell at least
50% of the outstanding Debentures, if WCAS CP III (the "DRAGGING
DEBENTUREHOLDER") decides to, and does, sell (including to an underwriter or an
initial purchaser in a Public Offering, pursuant to a bona fide sale to the
public or pursuant to Rule 144A or Regulation S under the Securities Act), all
of the face amount of the Debentures then owned by the Dragging Debentureholder
(a "SECTION 8.2 TRANSFER") then each Buyer (other than the Dragging
Debentureholder) (collectively, the "DRAG-ALONG

                                       23

<PAGE>

DEBENTUREHOLDERS") hereby agrees that, if requested by the Dragging
Debentureholder, it will Transfer in the Section 8.2 Transfer, subject to the
other provisions of this Section 8.2, on the terms of the Section 8.2 Transfer
as finally determined by the Dragging Debentureholder, including, without
limitation, time of payment, form and choice of consideration, inclusion of
Warrants and adjustments to purchase price, the face amount of the Debentures
(and number of Warrants, if applicable) equal to the face amount of the
Debentures (and number of Warrants, if applicable) owned by it multiplied by the
percentage of the then outstanding face amount of Debentures (and number of
Warrants) to which the Section 8.2 Transfer offer is applicable; PROVIDED,
HOWEVER, Chase Equity Associates, L.P. and its transferees and assigns shall
have the right to refuse to participate in any proposed Section 8.2 Transfer
giving rise to the rights of the Dragging Debentureholder set forth in this
Section 8.2(a) within five (5) Business Days following the receipt of the
Drag-Along Notice (as defined below) by sending written notice of its refusal to
the Dragging Debentureholder.

                  (b) The Dragging Debentureholder will give notice (the
"DRAG-ALONG NOTICE") to the Drag-Along Debentureholders of any Section 8.2
Transfer within five (5) Business Days following the Dragging Debentureholder's
determination to effect a Section 8.2 Transfer and, in any event, not less than
ten (10) Business Days prior to the proposed closing date for such Section 8.2
Transfer. The Drag-Along Notice will set forth the face amount of the Debentures
(and number of Warrants, if applicable) proposed to be so Transferred, the
manner in which the Section 8.2 Transfer will be effected, the name of the
proposed Transferee or acquiring Person (if applicable), the proposed amount and
form of consideration (and if such consideration consists in part or in whole of
property other than cash, the Dragging Debentureholder will provide such
information, to the extent reasonably available to the Dragging Debentureholder,
relating to such non-cash consideration as the Drag-Along Debentureholders
together may reasonably request in order to evaluate such non-cash
consideration), the face amount of the Debentures (and number of Warrants, if
applicable) sought and the other terms and conditions of the Section 8.2
Transfer. If any holders of the Debentures are given an option as to the form
and amount of consideration to be received, all holders of the Debentures shall
be given the same option. Each Drag-Along Debentureholder (x) shall agree to the
same covenants with respect to such Drag-Along Debentureholders, as appropriate,
as the Dragging Debentureholder agrees to in connection with the Section 8.2
Transfer; PROVIDED, HOWEVER, that the aggregate amount of liability of such
Drag-Along Debentureholder with respect to such covenants shall not exceed the
proceeds to such Drag-Along Debentureholder in connection with the Section 8.2
Transfer and (y) shall make such representations and warranties concerning its
title to the Debentures (and Warrants, if applicable) to be sold in connection
with the Section 8.2 Transfer and its authority to enter into and consummate the
Section 8.2 Transfer as the Dragging Debentureholder makes, but shall not be
required to make any other representations and warranties or indemnities other
than in respect of its own representations and warranties. If the Dragging
Debentureholder does not request that the Drag-Along Debentureholders
participate in a Section 8.2 Transfer, then each holder of Debentures shall have
the right to participate in such proposed transfer in accordance with its rights
under Section 8.1 above.

                  (c) Each Drag-Along Debentureholder will be responsible for
funding its proportionate share of any escrow arrangements in connection with
the Section 8.2 Transfer and for its proportionate share of any withdrawals
therefrom, including without limitation any such withdrawals that are made with
respect to claims arising out of agreements, covenants, representations,
warranties or other provisions relating the Section 8.2 Transfer that were made
by the Drag-Along Debentureholder.

                  (d) Each Drag-Along Debentureholder will be responsible for
its proportionate share of the Costs of the Section 8.2 Transfer to the extent
not paid or reimbursed by Concentra or another Person (other than the Dragging
Debentureholder); PROVIDED that such Section 8.2 Transfer is consummated and the
liability for such Costs shall not exceed the total purchase price received by
such Drag-Along Debentureholder for such Debentures (and Warrants, if
applicable). The Dragging Debentureholder shall be entitled to estimate the
Drag-Along Debentureholders' proportionate share of such Costs and to withhold
such amounts from payments to be made to the Drag-Along Debentureholder at the
time of closing of the Section 8.2 Transfer; PROVIDED that (i) such estimate
shall not preclude the Dragging Debentureholder from recovering additional
amounts from the Drag-Along Debentureholder in respect of such Drag-Along
Debentureholder's proportionate share of such Costs and (ii) the Dragging
Debentureholder shall reimburse the Drag-Along Debentureholder to the extent
actual amounts are ultimately less than the estimated amounts or any such
amounts are paid by Concentra or another Person (other than the Dragging
Debentureholder). If the Section 8.2 Transfer is not consummated within 180 days
from the date of the Drag-Along Notice, the Dragging Debentureholder must
deliver another Drag-Along Notice in order to exercise its rights under this
Section 8.2 with respect to such Section 8.2 Transfer.

                  (e) At the closing of such Section 8.2 Transfer, each of the
Dragging Debentureholders shall deliver one or more Debentures (and Warrants, if
applicable), properly endorsed for transfer and with all transfer taxes paid and
stamps affixed, which represent the face amount of the Debentures (and Warrants,
if applicable) then held by it and to be sold in such sale, duly endorsed for
transfer, against payment of the purchase price therefor by wire transfer to the
account or accounts specified by such Drag-Along Debentureholder.

                  (f) The proceeds from such Section 8.2 Transfer shall be
allocated among the selling holders of Debentures on a PRO RATA basis, based on
the face amount of the Debentures and number of Warrants then sold by each such
Debentureholder;

Agreement may be amended or waived if, but only if, such amendment or waiver is
in writing and signed in the case of an amendment, by each party to this

consents, and other materials that the Company provides to the members of the

Buyers for all out-of-pocket expenses (including the fees and disbursements of
counsel) reasonably incurred by them. .

                  Section 9.5 SUCCESSORS AND ASSIGNS. The provisions of this
Agreement shall be binding upon any inure to the benefit of the parties hereto
and their respective successors and assigns, PROVIDED that no party may assign,
delegate or otherwise transfer any of its rights or obligations under this
Agreement without the consent of each of the other parties hereto (it being
agreed that a merger (including the Merger) shall not be deemed an assignment
requiring the consent of Buyers). Notwithstanding the foregoing, a Buyer may
assign its rights under this Agreement or the right to receive any of the Units
under this Agreement to any general or limited partner of such Buyer or any
affiliates (as defined in Rule 405 promulgated under the Securities Act) thereof
(collectively, the "BUYER PARTIES" and each a "BUYER PARTY"), who are reasonably
acceptable to Concentra; PROVIDED that any such Buyer Party executes an
assumption agreement reasonably satisfactory in form and substance to Concentra
whereby such Buyer Party makes certain representations and warranties as set
forth in this Agreement and agrees to be bound, to the same extent as its
transferor, by the terms of this Agreement.

matter arising out of or in connection with, this Agreement or the transactions
contemplated hereby may only be brought in the United States District Court for
the Southern District of New York or any New York State court sitting in New
York City, and each of the parties hereby consents to the jurisdiction of such
courts (and of the appropriate appellate courts therefrom) in any such suit,
action or proceeding and irrevocably waives, to the fullest extent permitted by
law, any objection which it may now or hereafter have to the laying of the venue
of any such suit, action or proceeding in any such court or that any such suit,
action or proceeding which is brought in any such court has been brought in an
inconvenient forum. Process in any such suit, action or proceeding may be served
on any party anywhere in the world, whether within or without the jurisdiction
of any such court. Without limiting the foregoing, each party agrees that
service of process on such party as provided in Section 9.1 shall be deemed
effective service of process on such party.

shall be deemed to be excluded from this Agreement and the balance of this
Agreement shall be interpreted as if such provision were so excluded and shall

to any Award always to be a whole number.

stock and stock based awards held by employees of another corporation who
concurrently become employees of the Company as a result of a merger or
consolidation of the employing company with the Company or a Parent or
Subsidiary of the Company or the acquisition by the Company or a Parent or
Subsidiary of the Company of property or stock of the employing corporation. The

               (c) RULE 16b-3. To the extent that the Administrator determines
it to be desirable to qualify transactions hereunder as exempt under Rule 16b-3
of the Exchange Act, the transactions contemplated hereunder shall be structured
to satisfy the requirements for exemption under Rule 16b-3.

                                       4

without limitation, the circumstances under which issued and outstanding shares
of Common Stock owned by a Participant may be used by the Participant to
exercise an Option);

               (g)    to approve forms of agreements for use under the Plan;

               (h) to determine the terms and conditions, not inconsistent with
the terms of the Plan, of any Award granted hereunder, including without
limitation, the exercise price, the time or times when Options may be exercised
(which may be based on performance criteria), any vesting, acceleration or
waiver of forfeiture restrictions and any restriction or limitation regarding
any Award or the shares of Common Stock relating thereto, based in each case on
such factors as the Administrator, in its sole discretion, shall determine;

               (i) to reduce the exercise price of any Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option shall have declined since the date the Option was granted;

               (j)    to construe and interpret the terms of the Plan:

               (k)    to prescribe,  amend and rescind rules and  regulations
relating to the Plan;

                                       5
<PAGE>

               (l)    to modify or amend the terms of any Award;

               (m) to accelerate vesting periods with respect to outstanding

               (n) to authorize any person to execute on behalf of the Company
any instrument required to effect any Award granted by the Administrator; and

               (o) to exercise all other powers granted to the Administrator
under the Plan and make all other determinations deemed necessary or advisable
for administering the Plan.

        4.3. EFFECT OF ADMINISTRATOR'S DECISION. The Administrator's decisions,
determinations and interpretations shall be final and binding on all
Participants and any other holders of Options or Stock awarded under the Plan.

        4.4. EXPENSES, ETC. All expenses and liabilities incurred by the
Administrator in the administration of the Plan shall be borne by the Company.
The Administrator may employ attorneys, consultants, accountants or other

Section 6.8 of the Plan. No person other than an Employee, Consultant or
Non-Employee Director shall have any right to participate in the Plan. Any
person selected by the Administrator for participation during any one period

Participant for any other period. The maximum number of shares of Common Stock
which may be the subject of Awards granted to any one Employee or Consultant
under the Plan during any calendar year shall be 300,000 shares. For this
purpose, the grant of a new Award in substitution for outstanding Awards shall

        Section 6.    OPTIONS.

        6.1. AWARD. Subject to the provisions of the Plan, the Administrator may

less than 85% of the Fair Market Value of the Common Stock on the date of grant;
PROVIDED, that (i) in the case of an Incentive Stock Option, the exercise price
shall not be less than 100% of the Fair Market Value of the Common Stock at the

qualify as "performance-based compensation" within the meaning of Section 162(m)
of the Code, the exercise price shall not be less than 100% of the Fair Market
Value at the time of grant.

        6.3. VESTING. Each Option shall be exercisable at such times and subject
to such terms and conditions as the Administrator may specify in the applicable
Option agreement or thereafter. The Administrator may impose such conditions
with respect to the exercise of Options, including conditions relating to
applicable federal or state securities laws, as it considers necessary or
advisable.

        6.4. PAYMENT. Options granted under the Plan may provide for the payment
of the exercise price by delivery of cash or check in an amount equal to the

owned by the optionee, valued at their Fair Market Value on the date of such
option exercise, (b) delivery of a promissory note of the optionee to the
Company on terms determined by the Administrator, (c) delivery of an irrevocable
undertaking by a broker to deliver promptly to the Company sufficient funds to
pay the exercise price or delivery of irrevocable instructions to a broker to
deliver promptly to the Company cash or a check sufficient to pay the exercise
price, (d) payment of such other lawful consideration as the Administrator may
determine, or (e) any combination of the foregoing. In the event an optionee
pays some or all of the exercise price of an Option by delivery of shares of
Common Stock pursuant to clause (a) above, the Administrator may provide for the
automatic award of an Option for up to the number of shares so delivered.

        6.5. TRANSFERABILITY. Except as otherwise specifically approved by the
Administrator, each Option granted under the Plan shall provide that neither it
nor any interest therein may be transferred, assigned, pledged or hypothecated,
by the optionee or by operation of law otherwise than by will, the laws of
descent and distribution or a "qualified domestic relations order" (as defined
in the Code), and shall be exercised during the lifetime of the optionee only by
the optionee or a transferee pursuant to such a "qualified domestic relations
order". No Option or interest therein may be or be made subject to execution,
attachment or similar process.

        6.6 CANCELLATION AND NEW GRANT OF OPTIONS. The Board of Directors shall
have the authority to effect, at any time and from time to time, with the
consent of the affected optionees, (i) the cancellation of any or all
outstanding options under the Plan and the grant in substitution therefor of new
Options under the Plan covering the same or different numbers of shares of


                                       7
<PAGE>

Common Stock and having an option exercise price per share which may be lower or
higher than the exercise price per share of the canceled Options, or (ii) the
amendment of the terms of any and all outstanding Options under the Plan to
provide an option exercise price per share which is higher or lower than the

        6.7. INCENTIVE STOCK OPTIONS. Options granted under the Plan which are
intended to be Incentive Stock Options shall be subject to the following
additional terms and conditions:

               (a) All Incentive Stock Options granted under the Plan shall, at
the time of grant, be specifically designated as such in the option agreement

provisions shall be applicable to the Incentive Stock Option granted to such
individual:

                      (i)    The  purchase  price per share of the Common  Stock
subject to such Incentive Stock Option shall not be less than 110% of the Fair
Market Value of one share of Common Stock at the time of grant; and

                      (ii) The Option exercise period shall not exceed five

               (c) For so long as the Code shall so provide, options granted to
any Employee under the Plan (and any other incentive stock option plans of the
Company or its Subsidiaries) which are intended to constitute Incentive Stock
Options shall not constitute Incentive Stock Options to the extent that such
Options, in the aggregate, become exercisable for the first time in any one
calendar year for shares of Common Stock with an aggregate Fair Market Value
(determined as of the respective date or dates of grant) of more than $100,000.

               (d) No Incentive Stock Option may be exercised unless, at the

                      (i)    an  Incentive  Stock  Option  may be  exercised
(to the extent exercisable on the date the Participant ceased to be an Employee
of the Company or a Parent or Subsidiary) within the period of three months
after the date the Participant ceases to be an employee of the Company or such
Parent or Subsidiary (or within such lesser period as may be specified in the
applicable option agreement); PROVIDED, that the agreement with respect to such
Option may designate a longer exercise period and that the exercise after such
three-month period shall be treated as the exercise of a Non-Qualified Stock
Option under the Plan;

                      (ii) if the Participant dies while in the employ of the
Company, or

                                       8
<PAGE>

within three months after the Participant ceases to be an Employee, the
Incentive Stock Option (to the extent otherwise exercisable on the date of
death) may be exercised by the Participant's Designated Beneficiary within the
period of one year after the date of death (or within such lesser period as may
be specified in the applicable Option agreement); and

                      (iii) if the Participant becomes disabled (within the

while in the employ of the Company, the Incentive Stock Option may be exercised
(to the extent otherwise exercisable on the date of death) within the period of
one year after the date of such disability (or within such lesser period as may
be specified in the Option agreement). In the event of the Participant's death
during this one-year period, the Incentive Stock Option may be exercised by the
Participant's Designated Beneficiary within the period of one year from the date
the Participant became disabled or within such lesser period as may be specified
in the applicable Option agreement.

For all purposes of the Plan and any Option granted hereunder, (i) "employment"
shall be defined in accordance with the provisions of Section 1.421-7(h) of the
Treasury Regulations under the Code (or any successor regulations) and (ii) any
Option may provide that if such Option shall be assumed or a new Option
substituted therefor in a transaction to which Section 424(a) of the Code
applies, employment by such assuming or substituting corporation shall be
considered for all purposes of such Option to be employment by the Company.
Notwithstanding the foregoing provisions, no Incentive Stock Option may be
exercised after its expiration date.

to purchase 1,000 shares of Common Stock on the date of his or her initial
election to the Board of Directors, and an Annual Option to purchase 1,000
shares of Common Stock on the next business day following each annual meeting of
stockholders.

               (c) The exercise price of each Director Option will be 100% of
the Fair Market Value at the time of grant.

               (d) Director Options shall become exercisable six months after

serve as a director of the Company.

               (e) if a Non-Employee Director dies or becomes disabled becomes
disabled (within the meaning of Section 22(e)(3) of the Code or any successor
provision thereto) while a director of the Company, the Option may be exercised
(to the extent otherwise exercisable on the date of disability or death), by
such disabled director or, in the case of death, by the director's Designated
Beneficiary, in each case within the period of one year after the date of
disability or

                                       9

shall not be lower than 85% of Fair Market Value on the date of sale)
Unrestricted Stock to Participants.

        7.4. PAYMENT. The purchase price for each share of Restricted Stock and
Unrestricted Stock shall be determined by the Administrator and may not be less
than the par value of the Common Stock. Such purchase price may be paid in the
form of past services or such other lawful consideration as is determined by the
Board of Directors.

        7.5. CERTIFICATES. Stock certificates representing Shares of Restricted
Stock or Unrestricted Stock shall bear a legend referring to any restrictions

successor provision, and then only with respect to Reporting Persons.

                                       10

        8.2. DOCUMENTATION. Each Award under the Plan shall be evidenced by an
instrument delivered to the Participant specifying the terms and conditions
thereof and containing such other terms and conditions not inconsistent with the
provisions of the Plan as the Administrator considers necessary or advisable.
Such instruments may be in the form of agreements to be executed by both the
Company and the Participant, or certificates, letters or similar documents,
acceptance of which will evidence agreement to the terms thereof and of this
Plan.

        8.3. ADMINISTRATOR DISCRETION. Each type of Award may be made alone, in
addition to or in relation to any other type of Award. The terms of each type of
Award need not be identical, and the Administrator need not treat Participants
uniformly.

        8.4. TERMINATION OF STATUS. Subject to the provisions of Section 6, the
Administrator shall determine the effect on an Award of the disability, death,
retirement, authorized leave of absence or other termination of employment or
other status of a Participant and the extent to which, and the period during
which, the Participant's legal representative, guardian or Designated
Beneficiary may exercise rights under such Award.

        8.5. MERGERS, ETC. In the event of a consolidation or merger or sale of
all or substantially all of the assets of the Company in which outstanding
shares of Common Stock are exchanged for securities, cash or other property of
any other corporation or business entity (an "Acquisition"), the Board of
Directors or the board of directors of any corporation assuming the obligations
of the Company, may, in its discretion, take any one or more of the following
actions as to outstanding Awards: (i) provide that such Awards shall be assumed,
or substantially equivalent Awards shall be substituted, by the acquiring or
succeeding corporation (or an affiliate thereof) on such terms as the Board of
Directors determines to be appropriate; (ii) upon written notice to
Participants, provide that all unexercised Options will terminate immediately
prior to the consummation of such transaction unless exercised by the
Participant within a specified period following the date of such notice; (iii)
in the event of an Acquisition under the terms of which holders of the Common
Stock of the Company will receive upon consummation thereof a cash payment for
each share surrendered in the Acquisition (the "Acquisition Price"), make or
provide for a cash payment to Participants equal to the difference between (A)
the Acquisition Price times the number of shares of Common Stock subject to
outstanding Options (to the extent then exercisable at prices not in excess of
the Acquisition Price) and (B) the aggregate exercise price of all such
outstanding Options in exchange for the termination of such Options; and (iv)
provide that all or any outstanding Awards shall become exercisable or
realizable in full prior to the effective date of such Acquisition.

        8.6. DISSOLUTION OR LIQUIDATION. In the event of the proposed
dissolution or liquidation of the Company, to the extent that an Option has not
been previously exercised, it will terminate immediately prior to the
consummation of such proposed action. The Board of Directors may, in the
exercise of its sole discretion in such instances, declare that any Award shall
terminate as of a date fixed by the Board of Directors and give each Participant
the right to exercise his or her Option as to all or any of the shares subject
thereto, including shares as to which the Option would not otherwise be
exercisable, or may accelerate the termination of the Restricted Period of

                                       11
<PAGE>

any Stock Award.

        8.7. WITHHOLDING. The Participant shall pay to the Company, or make
provision satisfactory to the Administrator for payment of, any taxes required
by law to be withheld in respect of Awards under the Plan no later than the date
of the event creating the tax liability. In the Administrator's discretion, and
subject to such conditions as the Administrator may establish, such tax
obligations may be paid in whole or in part in shares of Common Stock, including
shares retained from the Award creating the tax obligation, valued at their Fair
Market Value. The Company may, to the extent permitted by law, deduct any such
tax obligations from any payment of any kind otherwise due to the Participant.

        8.8. FOREIGN NATIONALS. Awards may be made to Participants who are
foreign nationals or employed outside the United States on such terms and
conditions different from those specified in the Plan as the Administrator
considers necessary or advisable to achieve the purposes of the Plan or comply
with applicable laws.

        8.9. AMENDMENT OF AWARD. The Administrator may amend, modify or
terminate any outstanding Award, including substituting therefor another Award
of the same or a different type, changing the date of exercise or realization
and converting an Incentive Stock Option to a Non-Qualified Stock Option;
PROVIDED, that the Participant's consent to such action shall be required unless
the Administrator determines that the action, taking into account any related
action, would not materially and adversely affect the Participant.

        8.10. CONDITIONS ON DELIVERY OF COMMON STOCK. The Company will not be
obligated to deliver any shares of Common Stock pursuant to the Plan or to
remove restrictions from shares previously delivered under the Plan (i) until
all conditions of the Award have been satisfied or removed; (ii) until, in the
opinion of the Company's counsel, all applicable federal and state laws and
regulations have been complied with; (iii) if the outstanding Common Stock is at
the time listed on any stock exchange or admitted for trading on an automatic
quotation system, until the shares to be delivered have been listed or
authorized to be listed or quoted on such exchange or quotation system upon
official notice of notice of issuance; and (iv) until all other legal matters in
connection with the issuance and delivery of such shares have been approved by
the Company's counsel. If the sale of Common Stock has not been registered under
the Securities Act of 1933, as amended, the Company may require, as a condition
to exercise of the Award, such representations or agreements as the Company may
consider appropriate to avoid violation of such act and may require that the
certificates evidencing such Common Stock bear an appropriate legend restricting
transfer.

        Section 9.    MISCELLANEOUS

        9.1. NO RIGHT TO EMPLOYMENT OR OTHER STATUS. The grant of an Award shall
not be construed as giving a Participant the right to continued employment or
service for the Company. The Company expressly reserves the right at any time to
dismiss a Participant free from any liability or claim under the Plan, except as
expressly provided in the applicable Award.

                                       12
<PAGE>

        9.2. NO RIGHTS AS STOCKHOLDER. Subject to the provisions of the
applicable Award, no Participant or Designated Beneficiary shall have any rights
as a stockholder with respect to any shares of Common Stock to be distributed
under the Plan until he or she becomes the record holder thereof.

        9.3. EXCLUSION FROM BENEFIT COMPUTATIONS. No amounts payable upon
exercise of Awards granted under the Plan shall be considered salary, wages or
compensation to Participants for purposes of determining the amount or nature of
benefits that Participants are entitled to under any insurance, retirement or
other benefit plans or programs of the Company.

        9.4. INABILITY TO OBTAIN AUTHORITY. The inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such shares as to which such requisite
authority shall not have been obtained.

        9.5. GRANTS EXCEEDING ALLOTTED SHARES. If the shares of Common Stock
covered by an Award exceeds, as of the date of grant, the number of Shares which
may be issued under the Plan without additional stockholder approval, such Award
shall be void with respect to such excess stock, unless such additional
stockholder approval is obtained in a timely manner.

        9.6.   EFFECTIVE DATE AND TERM.

               (a) EFFECTIVE DATE. The Plan shall become effective on August 17,
1999, the date of its adoption by the Board of Directors, but no Incentive Stock
Option granted under the Plan shall become exercisable unless and until the Plan
shall have been approved by the Company's stockholders. If such stockholder
approval is not obtained within twelve months after the date of the Board of
Director's adoption of the Plan, no Options previously granted under the Plan
shall be deemed to be Incentive Stock Options and no Incentive Stock Options
shall be granted thereafter under the Plan. Amendments to the Plan not requiring
stockholder approval shall become effective when adopted by the Board of
Directors; amendments requiring stockholder approval shall become effective when
adopted by the Board of Directors, but no Incentive Stock Option granted after
the date of such amendment shall become exercisable (to the extent that such
amendment to the Plan was required to enable the Company to grant such Incentive
Stock Option to a particular optionee) unless and until such amendment shall
have been approved by the Company's stockholders. If such stockholder approval
is not obtained within twelve months of the Board of Director's adoption of such
amendment, any Incentive Stock Options granted on or after the date of such
amendment shall terminate to the extent that such amendment to the Plan was
required to enable the Company to grant such Option to a particular optionee.
Subject to the limitations set forth in this Section 9.6(a), Awards may be made
under the Plan at any time after the effective date and before the date fixed
for termination of the Plan.

               (b) TERMINATION. The Plan shall terminate upon the earlier of (i)
the close of business on the day next preceding the tenth anniversary of the
date of its adoption by the Board of Directors, (ii) the date on which all
shares available for issuance under the Plan shall have

                                       13
<PAGE>

been issued pursuant to Awards under the Plan, or (iii) by action of the Board
of Directors. No Award may be granted hereunder after termination of the Plan.
The termination or amendment of the Plan shall not alter or impair any rights or
obligations under theretofore granted under the Plan.

        9.7. AMENDMENT OF PLAN. The Board of Directors may amend, suspend or
terminate the Plan or any portion thereof at any time; PROVIDED, that no
amendment shall be made without stockholder approval if such approval is
necessary to comply with any applicable tax or regulatory requirement (it being
understood that prior to any such approval, Awards may be made under the Plan
expressly subject to such approval); and PROVIDED FURTHER, that, in accordance
with Section 8.9, the Participant's consent to any such action with respect to
its effect on any outstanding Award shall be required unless the Administrator
determines that the action, taking into account any related action, would not
materially and adversely affect the Participant.

        9.8. GOVERNING LAW. The provisions of the Plan shall be governed by and
interpreted in accordance with the laws of the State of Delaware.

<PAGE>

Company or any of its  subsidiaries  or affiliates  which he may then possess or
have under his control.

        3.     COMPENSATION AND RELATED MATTERS.

               (a) BASE SALARY.  Executive  shall  receive a base salary paid by
the Company  ("Base  Salary") at the annual rate of Two Hundred  Sixty  Thousand
Dollars   ($260,000)  during  each  calendar  year  of  the  Term,   payable  in
substantially  equal monthly  installments (or such other more frequent times as
executives of the Company  normally are paid). In addition,  the Company's Board
of  Directors  or Option and  Compensation  Committee  of the Board of Directors
shall, in good faith,  consider  granting  increases in the Base Salary based on
such factors as Executive's  performance and the growth and/or  profitability of
the Company, but the Company shall have no obligation to grant such increases in
compensation.

               (b) BONUS PAYMENTS.  Executive  shall be entitled to receive,  in
addition  to the Base  Salary,  such  bonus  payments,  if any,  as the Board of
Directors or the Option and Compensation Committee of the Board of Directors may
specify.

               (c)  EXPENSES.  During  the  term  of his  employment  hereunder,
Executive shall be entitled to receive prompt  reimbursement  for all reasonable
expenses  incurred  by him (in  accordance  with  the  policies  and  procedures
established  by the Board of  Directors  for its senior  executive  officers) in
performing  services  hereunder,   provided  that  Executive  properly  accounts
therefor in accordance with Company policy.

               (d) OTHER BENEFITS. The Company shall not make any changes in any
employee  benefit  plans or other  arrangements  in effect on the date hereof or
subsequently  in  effect  in  which   Executive   currently  or  in  the  future
participates (including,  without limitation,  each pension and retirement plan,
supplemental pension and retirement plan, savings and profit sharing plan, stock
or unit ownership plan,  stock or unit purchase plan, stock or unit option plan,
life insurance plan,  medical  insurance  plan,  disability  plan,  dental plan,
health-and-accident  plan, or any other similar plan or arrangement)  that would
adversely affect Executive's rights or benefits  thereunder,  unless such change
occurs  pursuant to a program  applicable  to all  executives of the Company and
does not  result in a  proportionately  greater  reduction  in the  rights of or
benefits to  Executive  as compared  with any other  executive  of the  Company.
Executive  shall be entitled to  participate  in or receive  benefits  under any
employee benefit plan or other  arrangement made available by the Company now or
in the future to its senior  executive  officers and key  management  employees,
subject to and on a basis  consistent  with the terms,  conditions,  and overall
administration of such plan or arrangement.  Nothing paid to Executive under any
plan or arrangement presently in effect or made available in the future shall be
deemed  to be in lieu of the  Base  Salary  payable  to  Executive  pursuant  to
paragraph (a) of this Section 3.

               (e)  VACATIONS.  Executive  shall be  entitled  to ten (10)  paid
vacation days for the period from the date of this  Agreement  through  December
31, 1999.  Executive shall be entitled to twenty (20) paid vacation days in each
calendar year commencing on or after January 1, 2000, or such additional  number
as may be determined by the Board of Directors  from time to


                                       3
<PAGE>

time.  For purposes of this Section 3(e),  weekends  shall not count as vacation
days and  Executive  shall also be  entitled to all paid  holidays  given by the
Company to its senior executive officers.

               (f)  PERQUISITES.  Executive  shall be  entitled  to receive  the
perquisites and fringe benefits appertaining to senior executive officers of the
Company in accordance  with any practice  established by the Board of Directors.
In  the  event  Executive's  employment  hereunder  is  terminated  (whether  by
Executive  or the  Company) for any reason  whatsoever  (other than  Executive's
death), then the Company shall, at Executive's written request and to the extent
permitted by the terms of such policies and applicable law, assign and convey to
Executive any life insurance  policies  maintained by the Company on the life of
Executive,  who shall thereafter be solely responsible,  at his election, to pay
all  premiums  payable  after such  assignment  and  conveyance  to maintain the
coverage under such policies with respect to Executive.  Executive  shall not be
required  to pay any  money or other  consideration  to the  Company  upon  such
assignment  and  conveyance,  it being  acknowledged  and agreed by the  parties
hereto that Executive's  execution and delivery hereof  constitute  adequate and
satisfactory consideration for such assignment and conveyance.

               (g) PRORATION.  Excepting only payments  pursuant to Section 3(b)
for  calendar  year 1999  (which  payments  shall be based upon a full  calendar
year), any payments or benefits payable to Executive hereunder in respect of any
calendar  year during  which  Executive is employed by the Company for less than
the  entire  year,   unless  otherwise   provided  in  the  applicable  plan  or
arrangement,  shall be  prorated in  accordance  with the number of days in such
calendar year during which he is so employed.

        4. EXECUTIVE'S OFFICE AND RELOCATION.  Executive shall primarily perform
his duties and  responsibilities  hereunder at the Company's  offices located at
5080  Spectrum  Drive,  Addison,  Texas (or at such  other  location  within the
Dallas,  Texas,  metropolitan  area,  to which  the  Company  may in the  future
relocate such  principal  executive  offices),  except for  reasonable  required
travel on the Company's  business.  If the Company requests  Executive to report
for the performance of his services hereunder on a regular or permanent basis at
any location or office more than thirty-five (35) miles from the office location
described in the first sentence of this Section 4, and Executive  agrees to such
change,  the Company  shall pay  Executive's  reasonable  relocation  and moving
expenses,  including,  but not  limited  to,  the cost of moving  his  immediate
family,  expenses  incurred  while  seeking  new  housing  (including  travel by
Executive's  spouse) and temporary living expenses  incurred by Executive or his
family for up to one hundred eighty (180) days.

        5. TERMINATION.  Executive's  employment  hereunder may be terminated by
the Company or Executive,  as applicable,  without any breach of this Agreement,
only under the following circumstances.

               (a) DEATH.  Executive's employment hereunder shall terminate upon
his death.

               (b) DISABILITY.  If, as a result of Executive's incapacity due to
physical or mental illness,  Executive  shall have been unable,  with reasonable
accommodation,   to  perform  the



                                       4
<PAGE>

essential functions of his duties and responsibilities  hereunder on a full time
basis for one hundred eighty (180) consecutive  calendar days, and within thirty
(30) days after written  notice of  termination is given (which may occur before
or after the end of such one hundred  eighty (180) day period)  Executive  shall
not have  returned to the  performance  of his  material  managerial  duties and
responsibilities  hereunder  on a full time basis,  the  Company  may  terminate
Executive's employment hereunder.

               (c) CAUSE. Subject to the provisions of Section 7(d), the Company
may terminate  Executive's  employment hereunder for Cause. For purposes of this
Agreement,  the Company shall have "Cause" to terminate  Executive's  employment
hereunder upon:

or gross  negligence  in the  performance  of  Executive's  material  duties and
responsibilities   hereunder  (other  than  any  such  failure   resulting  from
Executive's  incapacity  due to physical or mental illness or any such actual or
anticipated  failure  after the  issuance  of a Notice of  Termination  for Good
Reason (as hereinafter defined) by Executive);

                      (2) The  commission by Executive of dishonesty or fraud of
a material nature in connection with the performance of his duties hereunder, or

performance of his duties hereunder;

                      (3) The conviction of Executive, or the entering of a plea
of nolo contendere by Executive, with respect to a felony;

                      (4)  Unprofessional  or  unethical  conduct  of a material
nature by Executive in connection with the  performance of his duties  hereunder
as determined in a final adjudication of any board, institution, organization or
governmental  agency  having any  privilege or right to pass upon the conduct of
Executive;

                      (5) Intentional,  willful, or grossly negligent conduct by
Executive  which  is  materially  detrimental  to  the  reputation,   character,
business, or standing of the Company, including,  without limitation, the use by
Executive of a controlled substance; or

Section  7(c),  and  at his  option,  Executive  may  terminate  his  employment

               For purposes of this  Agreement,  the  termination of Executive's
employment  hereunder by Executive  because of the occurrence of any one or more
of the following events shall be deemed to have occurred for "Good Reason":

adverse to those existing before such change;

                      (B) any removal by the Company of Executive  from,  or any
failure to reelect  Executive  to, the  positions  indicated in Section 1 hereof
except in connection  with  termination of  Executive's  employment for Cause or

Medical  Officer,  or a  material  change  in  the  nature  or  scope  of any of
Executive's authorities,  status, powers, functions, duties, or responsibilities

by Executive in good faith to be adverse to those existing before such change;

                      (B) a reduction  in  Executive's  Base Salary or any other
failure by the Company to comply with Section 3 hereof that is not  consented to

<PAGE>

                      (D)  a  failure  by  the  Company  or  any  subsidiary  or

        6. COMPENSATION UPON TERMINATION OR FAILURE TO RENEW. Executive shall be
entitled to the following  compensation from the Company upon the termination of
his  employment or upon the Company's  delivery of notice  pursuant to Section 1
that the Term of this Agreement  shall not following any anniversary of the date
hereof be automatically extended for an additional year.

               (a) DEATH.  If  Executive's  employment  shall be  terminated  by
reason of his death,  the  Company  shall pay to such  person as shall have been
designated in a notice filed with the Company prior to Executive's death, or, if
no such person shall be designated,  to his estate as a death benefit,  his Base
Salary to the date of his death in addition to any payments  Executive's spouse,
beneficiaries,  or estate may be entitled to receive  pursuant to any pension or
employee benefit plan or other  arrangement or life insurance policy  maintained
by the Company. In addition,  (x) the Company shall make payments of premiums to
continue the medical and dental  insurance  coverage of  Executive's  spouse and
children  under  age  twenty-five  (25) as in  effect  at and as of the  date of
Executive's  death (or to provide as similar  coverage as possible  for the same
premiums if the continuation of existing  coverage is not permitted) for one (1)
year  after  the date of  Executive's  death,  in each case to the  extent  such
coverage is available, and (y) the Company shall make a lump sum cash payment to
the appropriate  insurance  company(ies)  in an amount  sufficient to fully fund
future premium  payments  pursuant to Executive's  then existing  second-to-die,
split-dollar   insurance   policy(ies)   obtained  through  the  Company  and/or
OccuSystems, Inc.

               (b) DISABILITY. During any period that Executive fails to perform
his material  managerial  duties and  responsibilities  hereunder as a result of
incapacity  due to  physical  or mental  illness,  Executive  shall  continue to
receive his Base Salary and any bonus payments until  Executive's  employment is
terminated  pursuant to Section 5(b) hereof or until  Executive  terminates  his
employment  pursuant to Section  5(d)(2) hereof,  whichever first occurs.  After
such termination, the Company shall pay to Executive, on or before the fifth day
following the Date of Termination  (as  hereinafter  defined) his Base Salary to
the Date of  Termination.  In addition,  (x) the Company  shall make payments of
premiums as necessary to cause  Executive  and  Executive's  spouse and children
under age  twenty-five  (25) to continue to be covered by the medical and dental
insurance  as in effect at and as of the Date of  Termination  (or to provide as
similar  coverage  as possible  for the same  premiums  if the  continuation  of
existing  coverage  is not  permitted)  for  one  (1)  year  after  the  Date of
Termination,  in each case to the extent such coverage is available, and (y) the
Company  shall  make a lump  sum  cash  payment  to  the  appropriate  insurance
company(ies)  in an amount  sufficient  to fully fund  future  premium  payments
pursuant to  Executive's  then existing  second-to-die,  split-dollar  insurance
policy(ies) obtained through the Company and/or OccuSystems, Inc.

               (c) CAUSE.  If  Executive's  employment  shall be terminated  for
Cause,  the Company  shall pay  Executive  his Base  Salary  through the Date of
Termination  at the rate in


                                       7
<PAGE>

effect at the time Notice of  Termination  is given.  Such payments  shall fully
discharge the Company's obligations hereunder.

               (d) BREACH BY THE COMPANY,  FOR GOOD  REASON,  OR UPON FAILURE TO
RENEW.  If  (1) in  breach  of  this  Agreement,  the  Company  shall  terminate
Executive's  employment  (it being  understood  that a purported  termination of
Executive's  employment  by the  Company  pursuant  to  any  provision  of  this
Agreement that is disputed and finally  determined not to have been proper shall
be a termination by the Company in breach of this  Agreement),  or (2) Executive
shall  terminate his employment  for Good Reason,  or (3) the Company shall give
Executive  notice  pursuant  to Section 1 prior to any  anniversary  of the date
hereof that the Term of this Agreement shall not be  automatically  extended for
an  additional  year on any such  anniversary  date,  then the Company shall pay
Executive:

                      (A) his Base Salary through the Date of Termination at the
rate in effect at the time Notice of Termination is given;

                      (B) in lieu of any further  salary  payments to  Executive
for periods  subsequent  to the Date of  Termination,  the Company  shall pay as
severance  pay to  Executive  on or before the fifth day  following  the Date of
Termination  and on the fifth day of each of the eleven (11)  months  thereafter
(amounting  to a  total  of  twelve  (12)  months),  an  amount  in  cash  equal
one-twelfth  (1/12) of  Executive's  annual Base Salary at the rate in effect at
the time the Notice of Termination is given; and

                      (C) all benefits  payable  under the terms of any employee
benefit plan or other arrangement as of the Date of Termination.

               In addition,  (x) the Company  shall make payments of premiums as
necessary to cause  Executive  and  Executive's  spouse and  children  under age
twenty-five  (25) to continue to be covered by the medical and dental  insurance
as in effect at and as of the Date of  Termination  (or to  provide  as  similar
coverage  as possible  for the same  premiums  if the  continuation  of existing
coverage is not  permitted) for one (1) year after the Date of  Termination,  in
each case to the extent such  coverage is  available,  and (y) the Company shall
make a lump sum cash payment to the  appropriate  insurance  company(ies)  in an
amount  sufficient to fully fund future premium payments pursuant to Executive's
then existing second-to-die, split-dollar insurance policy(ies) obtained through
the Company and/or OccuSystems, Inc.

               (e)  MITIGATION.  Executive shall not be required to mitigate the
amount of any payment provided for in this Section 6 by seeking other employment
or  otherwise;   provided,  HOWEVER,  that,  anything  herein  to  the  contrary
notwithstanding, in the event of the termination of Executive's employment prior
to a Change in Control (as defined in the  Concentra  Managed Care,  Inc.,  1997
Long-Term  Incentive Plan) which occurs after the consummation of the Merger (as
defined in that certain Amended and Restated Agreement and Plan of Merger, dated
as of March 24,  1999,  by and  between  Yankee  Acquisition  Corp.,  a Delaware
corporation,  and the Company)  (but not if  Executive's  employment  terminates
after such a Change in Control),  the amount of any payment  pursuant to Section
6(d)(B) and/or  pursuant to the first paragraph of



                                       8
<PAGE>

Section  6(f) shall be reduced by any  compensation  earned by  Executive as the
result of  employment  by another  employer  (whether  as a  director,  officer,
employee,  manager,  owner,  consultant,   independent  contractor,  advisor  or
otherwise)  after  the Date of  Termination  until the end of the  twelve  month
period of clause (B) of Section 6(d) above.

               (f)  ADDITIONAL   REASON.   If  Executive   shall  terminate  his
employment for Additional Reason, as well as for Good Reason,  then, in addition
to and not in lieu of any other  amounts  payable by the  Company  to  Executive
whether  pursuant to Section  6(d) or otherwise  (it being the  intention of the
parties  that,  upon  the  occurrence  of an event or  events  described  in the
definition or "Good Reason" and "Additional  Reason" in Section 5(d),  Executive
may terminate this Agreement for Good Reason AND for  Additional  Reason),  then
the Company shall pay Executive as  additional  severance  pay, on or before the
fifth  day  following  the  Date of  Termination,  a lump  sum in cash  equal to
Executive's full annual Base Salary at the rate in effect at the time the Notice
of  Termination is given (for a total of two (2) times  Executive's  full annual
Base Salary when combined with amounts payable pursuant to Section 6(d)(B)).

               In  addition,  the  Company  shall make  payments  of premiums as
necessary to cause  Executive  and  Executive's  spouse and  children  under age
twenty-five  (25) to continue to be covered by the medical and dental  insurance
as in effect at and as of the Date of  Termination  (or to  provide  as  similar
coverage  as possible  for the same  premiums  if the  continuation  of existing
coverage  is not  permitted)  for one (1) year in  addition  to the one (1) year
provided for under Section 6(d) (for a total of two (2) years) after the Date of
Termination, in each case to the extent such coverage is available.

        7.     OTHER PROVISIONS RELATING TO TERMINATION.

               (a)  NOTICE  OF  TERMINATION.   Any  termination  of  Executive's
employment by the Company or by Executive (other than termination because of the
death of Executive)  shall be  communicated  by written Notice of Termination to
the  other  party  hereto.  For  purposes  of  this  Agreement,   a  "Notice  of
Termination"  shall mean a notice which shall indicate the specific  termination
provision in this Agreement relied upon and shall set forth in reasonable detail
the facts and  circumstances  claimed  to  provide  a basis for  termination  of
Executive's employment under the provision so indicated.

               (b) DATE OF TERMINATION. For purposes of this Agreement, "Date of
Termination"  shall mean:  (1) if  Executive's  employment  is terminated by his
death,  the date of his  death;  (2) if  Executive's  employment  is  terminated
because of a disability  pursuant to Section  5(b),  then thirty (30) days after
Notice of Termination is given  (provided that Executive shall not have returned
to the  performance  of his duties on a full-time  basis during such thirty (30)
day period);  (3) if  Executive's  employment  is  terminated by the Company for
Cause or by  Executive  for Good  Reason  and/or for  Additional  Reason,  then,
subject  to  Sections  7(c)  and  7(d),  the date  specified  in the  Notice  of
Termination;  (4) if the Company gives  Executive  notice  pursuant to Section 1
prior to any  anniversary  of the date  hereof  that the Term of this  Agreement
shall  not  be  automatically  extended  for an  additional  year  on  any  such
anniversary  date, the date upon which



                                       9
<PAGE>

the Term expires; and (5) if Executive's  employment is terminated for any other
reason, the date on which a Notice of Termination is given.

               (c) GOOD REASON AND/OR ADDITIONAL REASON.  Upon the occurrence of
an event described in clauses (A) through (E) of the definition of "Good Reason"
in Section 5(d), and/or upon the occurrence of an event described in clauses (A)
through (D) of the definition of "Additional Reason" in Section 5(d),  Executive
may terminate his employment hereunder for Good Reason and/or Additional Reason,
as  applicable,  within one hundred  eighty  (180) days  thereafter  by giving a
Notice of  Termination  to the  Company  to that  effect.  If the  effect of the
occurrence  of the event  giving rise to Good Reason  and/or  Additional  Reason
under Section 5(d) may be cured,  the Company shall have the opportunity to cure
any  such  effect  for a  period  of  thirty  (30)  days  following  receipt  of
Executive's Notice of Termination. If the Company fails to cure any such effect,
the termination for Good Reason and/or  Additional Reason shall become effective
on the date specified in Executive's  Notice of  Termination.  If Executive does
not give such Notice of  Termination  to the Company,  then this  Agreement will
remain in effect; PROVIDED,  HOWEVER, that the failure of Executive to terminate
this  Agreement for Good Reason and/or  Additional  Reason shall not be deemed a
waiver of  Executive's  right to terminate his employment for Good Reason and/or
Additional Reason upon the occurrence of a subsequent event described in Section
5(d) in accordance with the terms of this Agreement.

               (d) CAUSE. In the case of any termination of Executive for Cause,
the Company will give Executive a Notice of Termination describing in reasonable
detail, the facts or circumstances giving rise to Executive's  termination (and,
if  applicable,  the action  required  to cure same) and will  permit  Executive
thirty  (30)  days  to cure  such  failure  to  comply  or  perform.  Cause  for
Executive's  termination will not be deemed to exist until the expiration of the
foregoing  cure period,  so long as Executive  continues to use his best efforts
during  the cure  period  to cure  such  failure.  If  within  thirty  (30) days
following  Executive's  receipt of a Notice of Termination for Cause,  Executive
has not cured the facts or circumstances giving rise to Executive's  termination
for Cause,  then Executive's  termination for Cause shall be effective as of the
date specified in the Notice of Termination.

               (e)  INTEREST.  Until paid,  all past due amounts  required to be
paid by the Company under any provision of this Agreement shall bear interest at
the highest  non-usurious rate permitted by applicable federal,  state, or local
law.

        8.     SUCCESSORS; BINDING AGREEMENT.

               (a)  SUCCESSORS.  This Agreement shall be binding upon, and inure
to the benefit of, the  Company,  Executive,  and their  respective  successors,
assigns, personal and legal representatives,  executors, administrators,  heirs,
distributees, devisees, and legatees, as applicable.

               (b) ASSUMPTION.  The Company will require any successor  (whether
direct or indirect, by purchase of securities,  merger,  consolidation,  sale of
assets,  or otherwise) to all or substantially  all of the business or assets of
the Company,  by an agreement in form and substance



                                       10
<PAGE>

reasonably  satisfactory to Executive, to expressly assume this Agreement and to
agree to perform  this  Agreement in the same manner and to the same extent that
the  Company  would be required  to perform it if no such  succession  had taken
place.   Failure  of  the  Company  to  obtain  such  agreement   prior  to  the
effectiveness  of any such  succession  shall be a breach of this  Agreement and
shall entitle  Executive to compensation from the Company in the same amount and
on the same terms as he would be  entitled to  hereunder  if he  terminated  his
employment for Good Reason (and, if such  succession  occurs on or before August
17,  2000,  in the same  amount and on the same terms as he would be entitled to
hereunder if he terminated his employment  for Additional  Reason),  except that
for  purposes  of  implementing  the  foregoing,  the  date on  which  any  such
succession becomes effective shall be deemed the Date of Termination.

               (c) CERTAIN  PAYMENTS.  If Executive should die while any amounts
would still be payable to him  hereunder if he had  continued to live,  all such
amounts,  unless otherwise provided herein, shall be paid in accordance with the
terms of this Agreement to Executive's  devisee,  legatee, or other designee or,
if there be no such designee, to Executive's estate.

        9.  NOTICE.  For purposes of this  Agreement,  all notices and all other
communications  provided for in this Agreement  shall be in writing and shall be
deemed  to have been  duly  given  when (a)  delivered  personally,  (b) sent by
facsimile or similar electronic device and confirmed, (c) delivered by overnight
express, or (d) if sent by any other means, upon receipt.  Notices and all other
communications provided for in this Agreement shall be addressed as follows:

        10.  MISCELLANEOUS.  No  provision  of this  Agreement  may be modified,
waived, or discharged unless such waiver,  modification,  or discharge is agreed
to in a written  instrument  signed by Executive  and the Company.  No waiver by
either party hereto of, or compliance  with,  any condition or provision of this
Agreement  to be  performed  by such  other  party  shall be  deemed a waiver of
similar or  dissimilar  provisions  or conditions at the same or at any prior or
subsequent time. No agreements or representations, oral or otherwise, express or
implied,  with  respect to the  subject  matter  hereof have been made by either
party  which  are not set  forth  expressly  in this  Agreement.  The  validity,
interpretation,  construction,  and  performance  of  this  Agreement  shall  be
governed  by the laws of the  State of  Delaware,  excluding  any  choice-of-law
provisions thereof.

        11.  ATTORNEY  FEES.  All legal fees and costs  incurred by Executive in
connection  with  the  resolution  of any  dispute  or  controversy  under or in
connection  with this Agreement  shall be reimbursed by the Company to Executive
as bills for such  services are  presented  by Executive to the Company,  unless
such dispute or  controversy  is found to have been brought not in good faith or
without merit by a court of competent jurisdiction.

        12.  VALIDITY.  The invalidity or  unenforceability  of any provision or
provisions of this Agreement shall not affect the validity or  enforceability of
any other  provision  of this  Agreement,  which shall  remain in full force and
effect.

        13.   COUNTERPARTS.   This   Agreement   may  be   executed  in  several
counterparts,  each of which shall be deemed to be an original, but all of which
together will constitute one and the same agreement.

        14. ENTIRE AGREEMENT; EFFECTIVENESS. This Agreement shall be of no force

certain Amended and Restated Agreement and Plan of Merger, dated as of March 24,
1999, by and between Yankee Acquisition Corp., a Delaware  corporation,  and the
Company,  as such  agreement  may be  amended  from  time to  time);  upon  such
consummation,  this Agreement shall be in full force and effect.  This Agreement
constitutes the entire agreement between the parties with respect to the subject
matter  hereof  and  supersedes  in all  respects  any and all prior  employment
agreements  and/or severance  protection  letters,  agreements,  or arrangements
between Executive,  on the one hand, and the Company or any other predecessor in
interest  thereto or any of their  respective  subsidiaries,  on the other hand,
which  prior  employment   agreements  and/or  severance   protection   letters,
agreements,  and  arrangements,  if any, are hereby  cancelled and of no further
force or effect.

        15. RIGHT AND OPTION OF COMPANY TO REPURCHASE SHARES UPON TERMINATION OF
Employment.

               (a) In the event that, prior to an initial public offering of the
Company's  equity  securities,   Executive's  employment  with  the  Company  is
terminated  for any  reason,  the  Company



                                       12
<PAGE>

shall thereupon have the right and option,  but not the obligation,  to purchase
from Executive all or any part of the shares of common stock, par value $.01 per
share,  of  the  Company  (the  "Shares")  held  by  Executive  as of  the  date
Executive's employment so ceases at a purchase price equal to the greater of (1)
Sixteen and 50/100 Dollars ($16.50) per Share, and (2) the fair market value (as
hereinafter  defined) of such Shares as of the date  Executive's  employment  so
ceases.

               (b) The Company  may  exercise  the right and option  provided in
Section  15(a) above by giving  Executive a written  notice of such  election to
purchase  at any time  within  ninety  (90)  days  after  the  date  Executive's
employment  so ceases.  The closing for the  purchase by the Company of any such
Shares  pursuant to the provisions of said Section 15(a) shall take place at the
offices of the Company on the date specified in such written notice,  which date
shall be a  business  day not later  than  sixty  (60) days  after the date such
notice  is  given.  At such  closing,  Executive  will  deliver  or  cause to be
delivered  such Shares,  duly  endorsed  for  transfer,  against  payment of the
applicable  purchase  price  therefor.  Such purchase  price shall be payable to
Executive  in cash or other  immediately  available  funds.  To the  extent  the

<PAGE>

Company or any of its  subsidiaries  or affiliates  which he may then possess or
have under his control.

        3.     COMPENSATION AND RELATED MATTERS.

               (a) BASE SALARY.  Executive  shall  receive a base salary paid by
the Company ("Base Salary") at the annual rate of Two Hundred  Seventy  Thousand
Dollars   ($270,000)  during  each  calendar  year  of  the  Term,   payable  in
substantially  equal monthly  installments (or such other more frequent times as
executives of the Company  normally are paid). In addition,  the Company's Board
of  Directors  or Option and  Compensation  Committee  of the Board of Directors
shall, in good faith,  consider  granting  increases in the Base Salary based on
such factors as Executive's  performance and the growth and/or  profitability of
the Company, but the Company shall have no obligation to grant such increases in
compensation.

               (b) BONUS PAYMENTS.  Executive  shall be entitled to receive,  in
addition  to the Base  Salary,  such  bonus  payments,  if any,  as the Board of
Directors or the Option and Compensation Committee of the Board of Directors may
specify.

               (c)  EXPENSES.  During  the  term  of his  employment  hereunder,
Executive shall be entitled to receive prompt  reimbursement  for all reasonable
expenses  incurred  by him (in  accordance  with  the  policies  and  procedures
established  by the Board of  Directors  for its senior  executive  officers) in
performing  services  hereunder,   provided  that  Executive  properly  accounts
therefor in accordance with Company policy.

               (d) OTHER BENEFITS. The Company shall not make any changes in any
employee  benefit  plans or other  arrangements  in effect on the date hereof or
subsequently  in  effect  in  which   Executive   currently  or  in  the  future
participates (including,  without limitation,  each pension and retirement plan,
supplemental pension and retirement plan, savings and profit sharing plan, stock
or unit ownership plan,  stock or unit purchase plan, stock or unit option plan,
life insurance plan,  medical  insurance  plan,  disability  plan,  dental plan,
health-and-accident  plan, or any other similar plan or arrangement)  that would
adversely affect Executive's rights or benefits  thereunder,  unless such change
occurs  pursuant to a program  applicable  to all  executives of the Company and
does not  result in a  proportionately  greater  reduction  in the  rights of or
benefits to  Executive  as compared  with any other  executive  of the  Company.
Executive  shall be entitled to  participate  in or receive  benefits  under any
employee benefit plan or other  arrangement made available by the Company now or
in the future to its senior  executive  officers and key  management  employees,
subject to and on a basis  consistent  with the terms,  conditions,  and overall
administration of such plan or arrangement.  Nothing paid to Executive under any
plan or arrangement presently in effect or made available in the future shall be
deemed  to be in lieu of the  Base  Salary  payable  to  Executive  pursuant  to
paragraph (a) of this Section 3.

               (e)  VACATIONS.  Executive  shall be  entitled  to ten (10)  paid
vacation days for the period from the date of this  Agreement  through  December
31, 1999.  Executive shall be entitled to twenty (20) paid vacation days in each
calendar year commencing on or after January 1, 2000, or such additional  number
as may be determined by the Board of Directors  from time to



                                       3
<PAGE>

time.  For purposes of this Section 3(e),  weekends  shall not count as vacation
days and  Executive  shall also be  entitled to all paid  holidays  given by the
Company to its senior executive officers.

               (f)  PERQUISITES.  Executive  shall be  entitled  to receive  the
perquisites and fringe benefits appertaining to senior executive officers of the
Company in accordance  with any practice  established by the Board of Directors.
In  the  event  Executive's  employment  hereunder  is  terminated  (whether  by
Executive  or the  Company) for any reason  whatsoever  (other than  Executive's
death), then the Company shall, at Executive's written request and to the extent
permitted by the terms of such policies and applicable law, assign and convey to
Executive any life insurance  policies  maintained by the Company on the life of
Executive,  who shall thereafter be solely responsible,  at his election, to pay
all  premiums  payable  after such  assignment  and  conveyance  to maintain the
coverage under such policies with respect to Executive.  Executive  shall not be
required  to pay any  money or other  consideration  to the  Company  upon  such
assignment  and  conveyance,  it being  acknowledged  and agreed by the  parties
hereto that Executive's  execution and delivery hereof  constitute  adequate and
satisfactory consideration for such assignment and conveyance.

               (g) PRORATION.  Excepting only payments  pursuant to Section 3(b)
for  calendar  year 1999  (which  payments  shall be based upon a full  calendar
year), any payments or benefits payable to Executive hereunder in respect of any
calendar  year during  which  Executive is employed by the Company for less than
the  entire  year,   unless  otherwise   provided  in  the  applicable  plan  or
arrangement,  shall be  prorated in  accordance  with the number of days in such
calendar year during which he is so employed.

        4. EXECUTIVE'S OFFICE AND RELOCATION.  Executive shall primarily perform
his duties and  responsibilities  hereunder at the Company's  offices located at
5080  Spectrum  Drive,  Addison,  Texas (or at such  other  location  within the
Dallas,  Texas,  metropolitan  area,  to which  the  Company  may in the  future
relocate such  principal  executive  offices),  except for  reasonable  required
travel on the Company's  business.  If the Company requests  Executive to report
for the performance of his services hereunder on a regular or permanent basis at
any location or office more than thirty-five (35) miles from the office location
described in the first sentence of this Section 4, and Executive  agrees to such
change,  the Company  shall pay  Executive's  reasonable  relocation  and moving
expenses,  including,  but not  limited  to,  the cost of moving  his  immediate
family,  expenses  incurred  while  seeking  new  housing  (including  travel by
Executive's  spouse) and temporary living expenses  incurred by Executive or his
family for up to one hundred eighty (180) days.

accommodation,   to  perform  the

essential functions of his duties and responsibilities  hereunder on a full time
basis for one hundred eighty (180) consecutive  calendar days, and within thirty

responsibilities  hereunder  on a full time basis,  the  Company  may  terminate
Executive's employment hereunder.

               (c) CAUSE. Subject to the provisions of Section 7(d), the Company
may terminate  Executive's  employment hereunder for Cause. For purposes of this

reason of his death,  the  Company  shall pay to such  person as shall have been
designated in a notice filed with the Company prior to Executive's death, or, if
no such person shall be designated,  to his estate as a death benefit,  his Base
Salary to the date of his death in addition to any payments  Executive's spouse,
beneficiaries,  or estate may be entitled to receive  pursuant to any pension or
employee benefit plan or other  arrangement or life insurance policy  maintained
by the Company. In addition,  (x) the Company shall make payments of premiums to
continue the medical and dental  insurance  coverage of  Executive's  spouse and
children  under  age  twenty-five  (25) as in  effect  at and as of the  date of

year  after  the date of  Executive's  death,  in each case to the  extent  such
coverage is available, and (y) the Company shall make a lump sum cash payment to
the appropriate  insurance  company(ies)  in an amount  sufficient to fully fund

OccuSystems, Inc.

               (b) DISABILITY. During any period that Executive fails to perform
his material  managerial  duties and  responsibilities  hereunder as a result of
incapacity  due to  physical  or mental  illness,  Executive  shall  continue to

following the Date of Termination  (as  hereinafter  defined) his Base Salary to
the Date of  Termination.  In addition,  (x) the Company  shall make payments of

similar  coverage  as possible  for the same  premiums  if the  continuation  of
existing  coverage  is not  permitted)  for  one  (1)  year  after  the  Date of
Termination,  in each case to the extent such coverage is available, and (y) the
Company  shall  make a lump  sum  cash  payment  to  the  appropriate  insurance
company(ies)  in an amount  sufficient  to fully fund  future  premium  payments
pursuant to  Executive's  then existing  second-to-die,  split-dollar  insurance
policy(ies) obtained through the Company and/or OccuSystems, Inc.

RENEW.  If  (1) in  breach  of  this  Agreement,  the  Company  shall  terminate
Executive's  employment  (it being  understood  that a purported  termination of
Executive's  employment  by the  Company  pursuant  to  any  provision  of  this
Agreement that is disputed and finally  determined not to have been proper shall
be a termination by the Company in breach of this  Agreement),  or (2) Executive
shall  terminate his employment  for Good Reason,  or (3) the Company shall give
Executive  notice  pursuant  to Section 1 prior to any  anniversary  of the date
hereof that the Term of this Agreement shall not be  automatically  extended for

                      (B) in lieu of any further  salary  payments to  Executive
for periods  subsequent  to the Date of  Termination,  the Company  shall pay as
severance  pay to  Executive  on or before the fifth day  following  the Date of
Termination  and on the fifth day of each of the eleven (11)  months  thereafter
(amounting  to a  total  of  twelve  (12)  months),  an  amount  in  cash  equal
one-twelfth  (1/12) of  Executive's  annual Base Salary at the rate in effect at
the time the Notice of Termination is given; and

                      (C) all benefits  payable  under the terms of any employee
benefit plan or other arrangement as of the Date of Termination.

               In addition,  (x) the Company  shall make payments of premiums as
necessary to cause  Executive  and  Executive's  spouse and  children  under age
twenty-five  (25) to continue to be covered by the medical and dental  insurance
as in effect at and as of the Date of  Termination  (or to  provide  as  similar
coverage  as possible  for the same  premiums  if the  continuation  of existing
coverage is not  permitted) for one (1) year after the Date of  Termination,  in
each case to the extent such  coverage is  available,  and (y) the Company shall
make a lump sum cash payment to the  appropriate  insurance  company(ies)  in an
amount  sufficient to fully fund future premium payments pursuant to Executive's
then existing second-to-die, split-dollar insurance policy(ies) obtained through
the Company and/or OccuSystems, Inc.

               (e)  MITIGATION.  Executive shall not be required to mitigate the
amount of any payment provided for in this Section 6 by seeking other employment
or  otherwise;   provided,  HOWEVER,  that,  anything  herein  to  the  contrary
notwithstanding, in the event of the termination of Executive's employment prior
to a Change in Control (as defined in the  Concentra  Managed Care,  Inc.,  1997
Long-Term  Incentive Plan) which occurs after the consummation of the Merger (as
defined in that certain Amended and Restated Agreement and Plan of Merger, dated
as of March 24,  1999,  by and  between  Yankee  Acquisition  Corp.,  a Delaware
corporation,  and the Company)  (but not if  Executive's  employment  terminates
after such a Change in Control),  the amount of any payment  pursuant to Section
6(d)(B) and/or  pursuant to the first paragraph of



                                       8
<PAGE>

Section  6(f) shall be reduced by any  compensation  earned by  Executive as the
result of  employment  by another  employer  (whether  as a  director,  officer,
employee,  manager,  owner,  consultant,   independent  contractor,  advisor  or
otherwise)  after  the Date of  Termination  until the end of the  twelve  month
period of clause (B) of Section 6(d) above.

               (f)  ADDITIONAL   REASON.   If  Executive   shall  terminate  his
employment for Additional Reason, as well as for Good Reason,  then, in addition
to and not in lieu of any other  amounts  payable by the  Company  to  Executive
whether  pursuant to Section  6(d) or otherwise  (it being the  intention of the
parties  that,  upon  the  occurrence  of an event or  events  described  in the
definition or "Good Reason" and "Additional  Reason" in Section 5(d),  Executive
may terminate this Agreement for Good Reason AND for  Additional  Reason),  then
the Company shall pay Executive as  additional  severance  pay, on or before the
fifth  day  following  the  Date of  Termination,  a lump  sum in cash  equal to
Executive's full annual Base Salary at the rate in effect at the time the Notice
of  Termination is given (for a total of two (2) times  Executive's  full annual
Base Salary when combined with amounts payable pursuant to Section 6(d)(B)).

               In  addition,  the  Company  shall make  payments  of premiums as
necessary to cause  Executive  and  Executive's  spouse and  children  under age
twenty-five  (25) to continue to be covered by the medical and dental  insurance
as in effect at and as of the Date of  Termination  (or to  provide  as  similar
coverage  as possible  for the same  premiums  if the  continuation  of existing
coverage  is not  permitted)  for one (1) year in  addition  to the one (1) year
provided for under Section 6(d) (for a total of two (2) years) after the Date of
Termination, in each case to the extent such coverage is available.

        7.     OTHER PROVISIONS RELATING TO TERMINATION.

               (a)  NOTICE  OF  TERMINATION.   Any  termination  of  Executive's
employment by the Company or by Executive (other than termination because of the
death of Executive)  shall be  communicated  by written Notice of Termination to
the  other  party  hereto.  For  purposes  of  this  Agreement,   a  "Notice  of
Termination"  shall mean a notice which shall indicate the specific  termination
provision in this Agreement relied upon and shall set forth in reasonable detail
the facts and  circumstances  claimed  to  provide  a basis for  termination  of
Executive's employment under the provision so indicated.

               (b) DATE OF TERMINATION. For purposes of this Agreement, "Date of
Termination"  shall mean:  (1) if  Executive's  employment  is terminated by his
death,  the date of his  death;  (2) if  Executive's  employment  is  terminated
because of a disability  pursuant to Section  5(b),  then thirty (30) days after
Notice of Termination is given  (provided that Executive shall not have returned
to the  performance  of his duties on a full-time  basis during such thirty (30)
day period);  (3) if  Executive's  employment  is  terminated by the Company for
Cause or by  Executive  for Good  Reason  and/or for  Additional  Reason,  then,
subject  to  Sections  7(c)  and  7(d),  the date  specified  in the  Notice  of
Termination;  (4) if the Company gives  Executive  notice  pursuant to Section 1
prior to any  anniversary  of the date  hereof  that the Term of this  Agreement
shall  not  be  automatically  extended  for an  additional  year  on  any  such
anniversary  date, the date upon which



                                       9
<PAGE>

the Term expires; and (5) if Executive's  employment is terminated for any other
reason, the date on which a Notice of Termination is given.

               (c) GOOD REASON AND/OR ADDITIONAL REASON.  Upon the occurrence of
an event described in clauses (A) through (E) of the definition of "Good Reason"
in Section 5(d), and/or upon the occurrence of an event described in clauses (A)
through (D) of the definition of "Additional Reason" in Section 5(d),  Executive
may terminate his employment hereunder for Good Reason and/or Additional Reason,
as  applicable,  within one hundred  eighty  (180) days  thereafter  by giving a
Notice of  Termination  to the  Company  to that  effect.  If the  effect of the
occurrence  of the event  giving rise to Good Reason  and/or  Additional  Reason
under Section 5(d) may be cured,  the Company shall have the opportunity to cure
any  such  effect  for a  period  of  thirty  (30)  days  following  receipt  of
Executive's Notice of Termination. If the Company fails to cure any such effect,
the termination for Good Reason and/or  Additional Reason shall become effective
on the date specified in Executive's  Notice of  Termination.  If Executive does
not give such Notice of  Termination  to the Company,  then this  Agreement will
remain in effect; PROVIDED,  HOWEVER, that the failure of Executive to terminate
this  Agreement for Good Reason and/or  Additional  Reason shall not be deemed a
waiver of  Executive's  right to terminate his employment for Good Reason and/or
Additional Reason upon the occurrence of a subsequent event described in Section
5(d) in accordance with the terms of this Agreement.

               (d) CAUSE. In the case of any termination of Executive for Cause,
the Company will give Executive a Notice of Termination describing in reasonable
detail, the facts or circumstances giving rise to Executive's  termination (and,
if  applicable,  the action  required  to cure same) and will  permit  Executive
thirty  (30)  days  to cure  such  failure  to  comply  or  perform.  Cause  for
Executive's  termination will not be deemed to exist until the expiration of the
foregoing  cure period,  so long as Executive  continues to use his best efforts
during  the cure  period  to cure  such  failure.  If  within  thirty  (30) days
following  Executive's  receipt of a Notice of Termination for Cause,  Executive
has not cured the facts or circumstances giving rise to Executive's  termination
for Cause,  then Executive's  termination for Cause shall be effective as of the
date specified in the Notice of Termination.

               (e)  INTEREST.  Until paid,  all past due amounts  required to be
paid by the Company under any provision of this Agreement shall bear interest at
the highest  non-usurious rate permitted by applicable federal,  state, or local
law.

        8.     SUCCESSORS; BINDING AGREEMENT.

               (a)  SUCCESSORS.  This Agreement shall be binding upon, and inure
to the benefit of, the  Company,  Executive,  and their  respective  successors,
assigns, personal and legal representatives,  executors, administrators,  heirs,
distributees, devisees, and legatees, as applicable.

               (b) ASSUMPTION.  The Company will require any successor  (whether
direct or indirect, by purchase of securities,  merger,  consolidation,  sale of
assets,  or otherwise) to all or substantially  all of the business or assets of
the Company,  by an agreement in form and substance



                                       10
<PAGE>

reasonably  satisfactory to Executive, to expressly assume this Agreement and to
agree to perform  this  Agreement in the same manner and to the same extent that
the  Company  would be required  to perform it if no such  succession  had taken
place.   Failure  of  the  Company  to  obtain  such  agreement   prior  to  the
effectiveness  of any such  succession  shall be a breach of this  Agreement and
shall entitle  Executive to compensation from the Company in the same amount and
on the same terms as he would be  entitled to  hereunder  if he  terminated  his
employment for Good Reason (and, if such  succession  occurs on or before August
17,  2000,  in the same  amount and on the same terms as he would be entitled to
hereunder if he terminated his employment  for Additional  Reason),  except that
for  purposes  of  implementing  the  foregoing,  the  date on  which  any  such
succession becomes effective shall be deemed the Date of Termination.

               (c) CERTAIN  PAYMENTS.  If Executive should die while any amounts
would still be payable to him  hereunder if he had  continued to live,  all such
amounts,  unless otherwise provided herein, shall be paid in accordance with the
terms of this Agreement to Executive's  devisee,  legatee, or other designee or,
if there be no such designee, to Executive's estate.

        9.  NOTICE.  For purposes of this  Agreement,  all notices and all other
communications  provided for in this Agreement  shall be in writing and shall be
deemed  to have been  duly  given  when (a)  delivered  personally,  (b) sent by
facsimile or similar electronic device and confirmed, (c) delivered by overnight
express, or (d) if sent by any other means, upon receipt.  Notices and all other
communications provided for in this Agreement shall be addressed as follows:

or to such other  address  as either  party may have  furnished  to the other in
writing in accordance herewith.

        10.  MISCELLANEOUS.  No  provision  of this  Agreement  may be modified,
waived, or discharged unless such waiver,  modification,  or discharge is agreed
to in a written  instrument  signed by Executive  and the Company.  No waiver by
either party hereto of, or compliance  with,  any condition or provision of this
Agreement  to be  performed  by such  other  party  shall be  deemed a waiver of
similar or  dissimilar  provisions  or conditions at the same or at any prior or
subsequent time. No agreements or representations, oral or otherwise, express or
implied,  with  respect to the  subject  matter  hereof have been made by either
party  which  are not set  forth  expressly  in this  Agreement.  The  validity,
interpretation,  construction,  and  performance  of  this  Agreement  shall  be
governed  by the laws of the  State of  Delaware,  excluding  any  choice-of-law
provisions thereof.

        11.  ATTORNEY  FEES.  All legal fees and costs  incurred by Executive in
connection  with  the  resolution  of any  dispute  or  controversy  under or in
connection  with this Agreement  shall be reimbursed by the Company to Executive
as bills for such  services are  presented  by Executive to the Company,  unless
such dispute or  controversy  is found to have been brought not in good faith or
without merit by a court of competent jurisdiction.

        12.  VALIDITY.  The invalidity or  unenforceability  of any provision or
provisions of this Agreement shall not affect the validity or  enforceability of
any other  provision  of this  Agreement,  which shall  remain in full force and
effect.

        13.   COUNTERPARTS.   This   Agreement   may  be   executed  in  several
counterparts,  each of which shall be deemed to be an original, but all of which
together will constitute one and the same agreement.

        14. ENTIRE AGREEMENT; EFFECTIVENESS. This Agreement shall be of no force
or effect  unless and until the  consummation  of the Merger (as defined in that
certain Amended and Restated Agreement and Plan of Merger, dated as of March 24,
1999, by and between Yankee Acquisition Corp., a Delaware  corporation,  and the
Company,  as such  agreement  may be  amended  from  time to  time);  upon  such
consummation,  this Agreement shall be in full force and effect.  This Agreement
constitutes the entire agreement between the parties with respect to the subject
matter  hereof  and  supersedes  in all  respects  any and all prior  employment
agreements  and/or severance  protection  letters,  agreements,  or arrangements
between Executive,  on the one hand, and the Company or any other predecessor in
interest  thereto or any of their  respective  subsidiaries,  on the other hand,
which  prior  employment   agreements  and/or  severance   protection   letters,
agreements,  and  arrangements,  if any, are hereby  cancelled and of no further
force or effect.

        15. RIGHT AND OPTION OF COMPANY TO REPURCHASE SHARES UPON TERMINATION OF
Employment.

               (a) In the event that, prior to an initial public offering of the
Company's  equity  securities,   Executive's  employment  with  the  Company  is
terminated  for any  reason,  the  Company



                                       12
<PAGE>

shall thereupon have the right and option,  but not the obligation,  to purchase
from Executive all or any part of the shares of common stock, par value $.01 per
share,  of  the  Company  (the  "Shares")  held  by  Executive  as of  the  date
Executive's employment so ceases at a purchase price equal to the greater of (1)
Sixteen and 50/100 Dollars ($16.50) per Share, and (2) the fair market value (as
hereinafter  defined) of such Shares as of the date  Executive's  employment  so
ceases.

               (b) The Company  may  exercise  the right and option  provided in
Section  15(a) above by giving  Executive a written  notice of such  election to
purchase  at any time  within  ninety  (90)  days  after  the  date  Executive's
employment  so ceases.  The closing for the  purchase by the Company of any such
Shares  pursuant to the provisions of said Section 15(a) shall take place at the
offices of the Company on the date specified in such written notice,  which date
shall be a  business  day not later  than  sixty  (60) days  after the date such
notice  is  given.  At such  closing,  Executive  will  deliver  or  cause to be
delivered  such Shares,  duly  endorsed  for  transfer,  against  payment of the
applicable  purchase  price  therefor.  Such purchase  price shall be payable to
Executive  in cash or other  immediately  available  funds.  To the  extent  the
Company  chooses not to exercise  such right and option under said Section 15(a)
to purchase any Shares,  such Shares shall  thereupon cease to be subject to the
provisions of this Section 15.

               (c) For the purposes of this Agreement,  "fair market value" of a
Share as of any date shall mean the value of such  stock as  determined  in good
faith by the Board of  Directors of the Company on a basis  consistent  with the
manner of  determining  the fair market value of the Company's  common stock for
purposes of offering the Company's common stock to equity investors.

        IN WITNESS  WHEREOF,  the parties have executed this Agreement as of the
date and year first above written.

prosecution of any legal action or proceeding initiated by Executive against the
Company or any  subsidiary  or  affiliate  of the  Company or the defense of any
legal action or  proceeding  initiated  against  Executive in his capacity as an
employee  or  director  of the Company or any  subsidiary  or  affiliate  of the
Company. Executive shall, at any time requested by the Company (either during or
after his  employment  with the  Company),  promptly  deliver to the Company all
memoranda,  notes, reports,  lists, and other documents (and all copies thereof)
relating to the business of the

                                       2

Company or any of its  subsidiaries  or affiliates  which he may then possess or
have under his control.

         3.       COMPENSATION AND RELATED MATTERS.

                  (a) BASE SALARY. Executive shall receive a base salary paid by
the Company  ("Base  Salary") at the annual rate of Two Hundred  Fifty  Thousand
Dollars   ($250,000)  during  each  calendar  year  of  the  Term,   payable  in
substantially  equal monthly  installments (or such other more frequent times as
executives of the Company  normally are paid). In addition,  the Company's Board
of  Directors  or Option and  Compensation  Committee  of the Board of Directors
shall, in good faith,  consider  granting  increases in the Base Salary based on
such factors as Executive's  performance and the growth and/or  profitability of
the Company, but the Company shall have no obligation to grant such increases in
compensation.

                  (b) BONUS PAYMENTS. Executive shall be entitled to receive, in
addition  to the Base  Salary,  such  bonus  payments,  if any,  as the Board of
Directors or the Option and Compensation Committee of the Board of Directors may
specify.

                  (c)  EXPENSES.  During the term of his  employment  hereunder,
Executive shall be entitled to receive prompt  reimbursement  for all reasonable
expenses  incurred  by him (in  accordance  with  the  policies  and  procedures
established  by the Board of  Directors  for its senior  executive  officers) in
performing  services  hereunder,   provided  that  Executive  properly  accounts
therefor in accordance with Company policy.

                  (d) OTHER BENEFITS.  The Company shall not make any changes in
any employee benefit plans or other arrangements in effect on the date hereof or
subsequently  in  effect  in  which   Executive   currently  or  in  the  future
participates (including,  without limitation,  each pension and retirement plan,
supplemental pension and retirement plan, savings and profit sharing plan, stock
or unit ownership plan,  stock or unit purchase plan, stock or unit option plan,
life insurance plan,  medical  insurance  plan,  disability  plan,  dental plan,
health-and-accident  plan, or any other similar plan or arrangement)  that would
adversely affect Executive's rights or benefits  thereunder,  unless such change
occurs  pursuant to a program  applicable  to all  executives of the Company and
does not  result in a  proportionately  greater  reduction  in the  rights of or
benefits to  Executive  as compared  with any other  executive  of the  Company.
Executive  shall be entitled to  participate  in or receive  benefits  under any
employee benefit plan or other  arrangement made available by the Company now or
in the future to its senior  executive  officers and key  management  employees,
subject to and on a basis  consistent  with the terms,  conditions,  and overall
administration of such plan or arrangement.  Nothing paid to Executive under any
plan or arrangement presently in effect or made available in the future shall be
deemed  to be in lieu of the  Base  Salary  payable  to  Executive  pursuant  to
paragraph (a) of this Section 3.

                  (e)  VACATIONS.  Executive  shall be entitled to ten (10) paid
vacation days for the period from the date of this  Agreement  through  December
31, 1999.  Executive shall be entitled to twenty (20) paid vacation days in each
calendar year commencing on or after January 1, 2000, or such additional  number
as may be determined by the Board of Directors  from time to time.

                                       3
<PAGE>

For purposes of this Section 3(e), weekends shall not count as vacation days and
Executive  shall also be entitled to all paid  holidays  given by the Company to
its senior executive officers.

                  (f)  PERQUISITES.  Executive  shall be entitled to receive the
perquisites and fringe benefits appertaining to senior executive officers of the
Company in accordance  with any practice  established by the Board of Directors.
In  the  event  Executive's  employment  hereunder  is  terminated  (whether  by
Executive  or the  Company) for any reason  whatsoever  (other than  Executive's
death), then the Company shall, at Executive's written request and to the extent
permitted by the terms of such policies and applicable law, assign and convey to
Executive any life insurance  policies  maintained by the Company on the life of
Executive,  who shall thereafter be solely responsible,  at his election, to pay
all  premiums  payable  after such  assignment  and  conveyance  to maintain the
coverage under such policies with respect to Executive.  Executive  shall not be
required  to pay any  money or other  consideration  to the  Company  upon  such
assignment  and  conveyance,  it being  acknowledged  and agreed by the  parties
hereto that Executive's  execution and delivery hereof  constitute  adequate and
satisfactory consideration for such assignment and conveyance.

                  (g)  PRORATION.  Excepting  only payments  pursuant to Section
3(b) for calendar year 1999 (which  payments shall be based upon a full calendar
year), any payments or benefits payable to Executive hereunder in respect of any
calendar  year during  which  Executive is employed by the Company for less than
the  entire  year,   unless  otherwise   provided  in  the  applicable  plan  or
arrangement,  shall be  prorated in  accordance  with the number of days in such
calendar year during which he is so employed.

         4. EXECUTIVE'S OFFICE AND RELOCATION. Executive shall primarily perform
his duties and  responsibilities  hereunder at the Company's  offices located at
5080  Spectrum  Drive,  Addison,  Texas (or at such  other  location  within the
Dallas,  Texas,  metropolitan  area,  to which  the  Company  may in the  future
relocate such  principal  executive  offices),  except for  reasonable  required
travel on the Company's  business.  If the Company requests  Executive to report
for the performance of his services hereunder on a regular or permanent basis at
any location or office more than thirty-five (35) miles from the office location
described in the first sentence of this Section 4, and Executive  agrees to such
change,  the Company  shall pay  Executive's  reasonable  relocation  and moving
expenses,  including,  but not  limited  to,  the cost of moving  his  immediate
family,  expenses  incurred  while  seeking  new  housing  (including  travel by
Executive's  spouse) and temporary living expenses  incurred by Executive or his
family for up to one hundred eighty (180) days.

         5. TERMINATION.  Executive's  employment hereunder may be terminated by
the Company or Executive,  as applicable,  without any breach of this Agreement,
only under the following circumstances.

                  (a)   DEATH.  Executive's employment hereunder shall terminate
upon his death.

                  (b) DISABILITY.  If, as a result of Executive's incapacity due
to physical or mental illness, Executive shall have been unable, with reasonable
accommodation,   to  perform  the

                                       4
<PAGE>

essential functions of his duties and responsibilities  hereunder on a full time
basis for one hundred eighty (180) consecutive  calendar days, and within thirty
(30) days after written  notice of  termination is given (which may occur before
or after the end of such one hundred  eighty (180) day period)  Executive  shall
not have  returned to the  performance  of his  material  managerial  duties and
responsibilities  hereunder  on a full time basis,  the  Company  may  terminate
Executive's employment hereunder.

                  (c) CAUSE.  Subject to the  provisions  of Section  7(d),  the
Company may terminate  Executive's  employment hereunder for Cause. For purposes

perform or gross  negligence in the  performance of Executive's  material duties
and  responsibilities  hereunder  (other than any such  failure  resulting  from
Executive's  incapacity  due to physical or mental illness or any such actual or
anticipated  failure  after the  issuance  of a Notice of  Termination  for Good
Reason (as hereinafter defined) by Executive);

                           (2) The  commission  by  Executive of  dishonesty  or

                           (3) The conviction of Executive, or the entering of a
plea of nolo contendere by Executive, with respect to a felony;

                           (4) Unprofessional or unethical conduct of a material
nature by Executive in connection with the  performance of his duties  hereunder
as determined in a final adjudication of any board, institution, organization or
governmental  agency  having any  privilege or right to pass upon the conduct of
Executive;

                           (5)  Intentional,   willful,   or  grossly  negligent
conduct  by  Executive  which  is  materially  detrimental  to  the  reputation,
character,  business, or standing of the Company, including, without limitation,
the use by Executive of a controlled substance; or

                           (6)  The  continued  breach  by  Executive  of any of

                           (B) any removal by the Company of Executive  from, or
any failure to reelect Executive to, the positions indicated in Section 1 hereof
except in connection  with  termination of  Executive's  employment for Cause or

be entitled to the following  compensation from the Company upon the termination
of his employment or upon the Company's delivery of notice pursuant to Section 1
that the Term of this Agreement  shall not following any anniversary of the date
hereof be automatically extended for an additional year.

                  (a) DEATH.  If Executive's  employment  shall be terminated by
reason of his death,  the  Company  shall pay to such  person as shall have been
designated in a notice filed with the Company prior to Executive's death, or, if
no such person shall be designated,  to his estate as a death benefit,  his Base
Salary to the date of his death in addition to any payments  Executive's spouse,
beneficiaries,  or estate may be entitled to receive  pursuant to any pension or
employee benefit plan or other  arrangement or life insurance policy  maintained
by the Company. In addition,  (x) the Company shall make payments of premiums to
continue the medical and dental  insurance  coverage of  Executive's  spouse and
children  under  age  twenty-five  (25) as in  effect  at and as of the  date of
Executive's  death (or to provide as similar  coverage as possible  for the same
premiums if the continuation of existing  coverage is not permitted) for one (1)
year  after  the date of  Executive's  death,  in each case to the  extent  such
coverage is available, and (y) the Company shall make a lump sum cash payment to
the appropriate  insurance  company(ies)  in an amount  sufficient to fully fund
future premium  payments  pursuant to Executive's  then existing  second-to-die,
split-dollar   insurance   policy(ies)   obtained  through  the  Company  and/or
OccuSystems, Inc.

                  (b)  DISABILITY.  During any period  that  Executive  fails to
perform his  material  managerial  duties and  responsibilities  hereunder  as a
result of incapacity due to physical or mental illness, Executive shall continue
to receive his Base Salary and any bonus payments until  Executive's  employment
is terminated pursuant to Section 5(b) hereof or until Executive  terminates his
employment  pursuant to Section  5(d)(2) hereof,  whichever first occurs.  After
such termination, the Company shall pay to Executive, on or before the fifth day
following the Date of Termination  (as  hereinafter  defined) his Base Salary to
the Date of  Termination.  In addition,  (x) the Company  shall make payments of
premiums as necessary to cause  Executive  and  Executive's  spouse and children
under age  twenty-five  (25) to continue to be covered by the medical and dental
insurance  as in effect at and as of the Date of  Termination  (or to provide as
similar  coverage  as possible  for the same  premiums  if the  continuation  of
existing  coverage  is not  permitted)  for  one  (1)  year  after  the  Date of
Termination,  in each case to the extent such coverage is available, and (y) the
Company  shall  make a lump  sum  cash  payment  to  the  appropriate  insurance
company(ies)  in an amount  sufficient  to fully fund  future  premium  payments
pursuant to  Executive's  then existing  second-to-die,  split-dollar  insurance
policy(ies) obtained through the Company and/or OccuSystems, Inc.

                  (c) CAUSE. If Executive's  employment  shall be terminated for
Cause,  the Company  shall pay  Executive  his Base  Salary  through the Date of
Termination  at the rate in

                                       7
<PAGE>

effect at the time Notice of  Termination  is given.  Such payments  shall fully
discharge the Company's obligations hereunder.

                  (d) BREACH BY THE COMPANY, FOR GOOD REASON, OR UPON FAILURE TO
RENEW.  If  (1) in  breach  of  this  Agreement,  the  Company  shall  terminate
Executive's  employment  (it being  understood  that a purported  termination of
Executive's  employment  by the  Company  pursuant  to  any  provision  of  this
Agreement that is disputed and finally  determined not to have been proper shall
be a termination by the Company in breach of this  Agreement),  or (2) Executive
shall  terminate his employment  for Good Reason,  or (3) the Company shall give
Executive  notice  pursuant  to Section 1 prior to any  anniversary  of the date
hereof that the Term of this Agreement shall not be  automatically  extended for
an  additional  year on any such  anniversary  date,  then the Company shall pay
Executive:

                           (A) his Base Salary  through the Date of  Termination
at the rate in effect at the time Notice of Termination is given;

                           (B)  in  lieu  of  any  further  salary  payments  to
Executive for periods subsequent to
the Date of Termination,  the Company shall pay as severance pay to Executive on
or before the fifth day following the Date of  Termination  and on the fifth day
of each of the eleven (11)  months  thereafter  (amounting  to a total of twelve
(12) months),  an amount in cash equal one-twelfth  (1/12) of Executive's annual
Base  Salary  at the rate in effect at the time the  Notice  of  Termination  is
given; and

                           (C) all  benefits  payable  under  the  terms  of any
employee benefit plan or other arrangement as of the Date of Termination.

                  In addition,  (x) the Company  shall make payments of premiums
as necessary to cause  Executive and  Executive's  spouse and children under age
twenty-five  (25) to continue to be covered by the medical and dental  insurance
as in effect at and as of the Date of  Termination  (or to  provide  as  similar
coverage  as possible  for the same  premiums  if the  continuation  of existing
coverage is not  permitted) for one (1) year after the Date of  Termination,  in
each case to the extent such  coverage is  available,  and (y) the Company shall
make a lump sum cash payment to the  appropriate  insurance  company(ies)  in an
amount  sufficient to fully fund future premium payments pursuant to Executive's
then existing second-to-die, split-dollar insurance policy(ies) obtained through
the Company and/or OccuSystems, Inc.

                  (e)  MITIGATION.  Executive  shall not be required to mitigate
the  amount of any  payment  provided  for in this  Section 6 by  seeking  other
employment  or  otherwise;  PROVIDED,  HOWEVER,  that,  anything  herein  to the
contrary  notwithstanding,  in the  event  of  the  termination  of  Executive's
employment  prior to a Change in Control  (as defined in the  Concentra  Managed
Care,  Inc., 1997 Long-Term  Incentive Plan) which occurs after the consummation
of the Merger (as defined in that  certain  Amended and Restated  Agreement  and
Plan of Merger,  dated as of March 24, 1999, by and between  Yankee  Acquisition
Corp.,  a  Delaware  corporation,  and  the  Company)  (but  not if  Executive's
employment terminates after such a Change in Control), the amount of any payment
pursuant to Section  6(d)(B) and/or  pursuant to the first  paragraph of


                                       8
<PAGE>

Section  6(f) shall be reduced by any  compensation  earned by  Executive as the
result of  employment  by another  employer  (whether  as a  director,  officer,
employee,  manager,  owner,  consultant,   independent  contractor,  advisor  or
otherwise)  after  the Date of  Termination  until the end of the  twelve  month
period of clause (B) of Section 6(d) above.

                  (f)  ADDITIONAL  REASON.  If  Executive  shall  terminate  his
employment for Additional Reason, as well as for Good Reason,  then, in addition
to and not in lieu of any other  amounts  payable by the  Company  to  Executive
whether  pursuant to Section  6(d) or otherwise  (it being the  intention of the
parties  that,  upon  the  occurrence  of an event or  events  described  in the
definition or "Good Reason" and "Additional  Reason" in Section 5(d),  Executive
may terminate this Agreement for Good Reason AND for  Additional  Reason),  then
the Company shall pay Executive as  additional  severance  pay, on or before the
fifth  day  following  the  Date of  Termination,  a lump  sum in cash  equal to
Executive's full annual Base Salary at the rate in effect at the time the Notice
of  Termination is given (for a total of two (2) times  Executive's  full annual
Base Salary when combined with amounts payable pursuant to Section 6(d)(B)).

                  In addition,  the Company  shall make  payments of premiums as
necessary to cause  Executive  and  Executive's  spouse and  children  under age
twenty-five  (25) to continue to be covered by the medical and dental  insurance
as in effect at and as of the Date of  Termination  (or to  provide  as  similar
coverage  as possible  for the same  premiums  if the  continuation  of existing
coverage  is not  permitted)  for one (1) year in  addition  to the one (1) year
provided for under Section 6(d) (for a total of two (2) years) after the Date of
Termination, in each case to the extent such coverage is available.

         7.       OTHER PROVISIONS RELATING TO TERMINATION.

                  (a) NOTICE OF  TERMINATION.  Any  termination  of  Executive's
employment by the Company or by Executive (other than termination because of the
death of Executive)  shall be  communicated  by written Notice of Termination to
the  other  party  hereto.  For  purposes  of  this  Agreement,   a  "Notice  of
Termination"  shall mean a notice which shall indicate the specific  termination
provision in this Agreement relied upon and shall set forth in reasonable detail
the facts and  circumstances  claimed  to  provide  a basis for  termination  of
Executive's employment under the provision so indicated.

                  (b) DATE OF TERMINATION. For purposes of this Agreement, "Date
of Termination"  shall mean: (1) if Executive's  employment is terminated by his
death,  the date of his  death;  (2) if  Executive's  employment  is  terminated
because of a disability  pursuant to Section  5(b),  then thirty (30) days after
Notice of Termination is given  (provided that Executive shall not have returned
to the  performance  of his duties on a full-time  basis during such thirty (30)
day period);  (3) if  Executive's  employment  is  terminated by the Company for
Cause or by  Executive  for Good  Reason  and/or for  Additional  Reason,  then,
subject  to  Sections  7(c)  and  7(d),  the date  specified  in the  Notice  of
Termination;  (4) if the Company gives  Executive  notice  pursuant to Section 1
prior to any  anniversary  of the date  hereof  that the Term of this  Agreement
shall  not  be  automatically  extended  for an  additional  year  on  any  such
anniversary  date, the date upon which


                                       9
<PAGE>

the Term expires; and (5) if Executive's  employment is terminated for any other
reason, the date on which a Notice of Termination is given.

                  (c) GOOD REASON AND/OR ADDITIONAL REASON.  Upon the occurrence
of an event  described  in clauses (A) through  (E) of the  definition  of "Good
Reason" in Section 5(d),  and/or upon the  occurrence  of an event  described in
clauses (A)  through (D) of the  definition  of  "Additional  Reason" in Section
5(d),  Executive may terminate his  employment  hereunder for Good Reason and/or
Additional  Reason,  as  applicable,   within  one  hundred  eighty  (180)  days
thereafter by giving a Notice of Termination  to the Company to that effect.  If
the effect of the  occurrence  of the event  giving rise to Good  Reason  and/or
Additional  Reason under  Section 5(d) may be cured,  the Company shall have the
opportunity  to cure any such effect for a period of thirty (30) days  following
receipt of Executive's  Notice of Termination.  If the Company fails to cure any
such effect,  the  termination  for Good Reason and/or  Additional  Reason shall
become effective on the date specified in Executive's Notice of Termination.  If
Executive  does not give such Notice of  Termination  to the Company,  then this
Agreement  will  remain  in  effect;  PROVIDED,  HOWEVER,  that the  failure  of
Executive to terminate this Agreement for Good Reason and/or  Additional  Reason
shall not be deemed a waiver of  Executive's  right to terminate his  employment
for Good Reason  and/or  Additional  Reason upon the  occurrence of a subsequent
event described in Section 5(d) in accordance with the terms of this Agreement.

                  (d) CAUSE.  In the case of any  termination  of Executive  for
Cause,  the Company will give  Executive a Notice of  Termination  describing in
reasonable  detail,  the  facts  or  circumstances  giving  rise to  Executive's
termination  (and,  if  applicable,  the action  required to cure same) and will
permit  Executive  thirty  (30) days to cure such  failure to comply or perform.
Cause  for  Executive's  termination  will  not be  deemed  to exist  until  the
expiration of the foregoing cure period,  so long as Executive  continues to use
his best efforts  during the cure period to cure such failure.  If within thirty
(30) days following  Executive's  receipt of a Notice of Termination  for Cause,
Executive has not cured the facts or  circumstances  giving rise to  Executive's
termination for Cause, then Executive's termination for Cause shall be effective
as of the date specified in the Notice of Termination.

                  (e) INTEREST.  Until paid, all past due amounts required to be
paid by the Company under any provision of this Agreement shall bear interest at
the highest  non-usurious rate permitted by applicable federal,  state, or local
law.

         8.       SUCCESSORS; BINDING AGREEMENT.

                  (a)  SUCCESSORS.  This  Agreement  shall be binding upon,  and
inure  to  the  benefit  of,  the  Company,   Executive,  and  their  respective
successors,   assigns,   personal   and   legal   representatives,    executors,
administrators, heirs, distributees, devisees, and legatees, as applicable.

                  (b)  ASSUMPTION.   The  Company  will  require  any  successor
(whether direct or indirect, by purchase of securities,  merger,  consolidation,
sale of assets,  or  otherwise) to all or  substantially  all of the business or
assets  of the  Company,  by an  agreement  in  form  and  substance


                                       10
<PAGE>

reasonably  satisfactory to Executive, to expressly assume this Agreement and to
agree to perform  this  Agreement in the same manner and to the same extent that
the  Company  would be required  to perform it if no such  succession  had taken
place.   Failure  of  the  Company  to  obtain  such  agreement   prior  to  the
effectiveness  of any such  succession  shall be a breach of this  Agreement and
shall entitle  Executive to compensation from the Company in the same amount and
on the same terms as he would be  entitled to  hereunder  if he  terminated  his
employment for Good Reason (and, if such  succession  occurs on or before August
17,  2000,  in the same  amount and on the same terms as he would be entitled to
hereunder if he terminated his employment  for Additional  Reason),  except that
for  purposes  of  implementing  the  foregoing,  the  date on  which  any  such
succession becomes effective shall be deemed the Date of Termination.

                  (c)  CERTAIN  PAYMENTS.  If  Executive  should  die  while any
amounts would still be payable to him hereunder if he had continued to live, all
such amounts, unless otherwise provided herein, shall be paid in accordance with
the terms of this Agreement to Executive's  devisee,  legatee, or other designee
or, if there be no such designee, to Executive's estate.

         9. NOTICE.  For purposes of this  Agreement,  all notices and all other
communications  provided for in this Agreement  shall be in writing and shall be
deemed  to have been  duly  given  when (a)  delivered  personally,  (b) sent by
facsimile or similar electronic device and confirmed, (c) delivered by overnight

waived, or discharged unless such waiver,  modification,  or discharge is agreed
to in a written  instrument  signed by Executive  and the Company.  No waiver by
either party hereto of, or compliance  with,  any condition or provision of this
Agreement  to be  performed  by such  other  party  shall be  deemed a waiver of
similar or  dissimilar  provisions  or conditions at the same or at any prior or
subsequent time. No agreements or representations, oral or otherwise, express or
implied,  with  respect to the  subject  matter  hereof have been made by either
party  which  are not set  forth  expressly  in this  Agreement.  The  validity,
interpretation,  construction,  and  performance  of  this  Agreement  shall  be
governed  by the laws of the  State of  Delaware,  excluding  any  choice-of-law
provisions thereof.

         11.  ATTORNEY  FEES.  All legal fees and costs incurred by Executive in
connection  with  the  resolution  of any  dispute  or  controversy  under or in
connection  with this Agreement  shall be reimbursed by the Company to Executive

without merit by a court of competent jurisdiction.

         12. VALIDITY.  The invalidity or  unenforceability  of any provision or
provisions of this Agreement shall not affect the validity or  enforceability of
any other  provision  of this  Agreement,  which shall  remain in full force and

March 24, 1999, by and between Yankee Acquisition Corp., a Delaware corporation,
and the Company,  as such agreement may be amended from time to time); upon such
consummation,  this Agreement shall be in full force and effect.  This Agreement
constitutes the entire agreement between the parties with respect to the subject
matter  hereof  and  supersedes  in all  respects  any and all prior  employment
agreements  and/or severance  protection  letters,  agreements,  or arrangements
between Executive,  on the one hand, and the Company or any other predecessor in
interest  thereto or any of their  respective  subsidiaries,  on the other hand,
which  prior  employment   agreements  and/or  severance   protection   letters,
agreements,  and  arrangements,  if any, are hereby  cancelled and of no further
force or effect.

         15. RIGHT AND OPTION OF COMPANY TO REPURCHASE  SHARES UPON  TERMINATION
OF EMPLOYMENT.

                  (a) In the event that,  prior to an initial public offering of
the Company's  equity  securities,  Executive's  employment  with the Company


                                       12
<PAGE>

is terminated  for any reason,  the Company shall  thereupon  have the right and
option,  but not the  obligation,  to purchase from Executive all or any part of
the  shares of common  stock,  par value  $.01 per share,  of the  Company  (the
"Shares") held by Executive as of the date Executive's employment so ceases at a
purchase price equal to the greater of (1) Sixteen and 50/100  Dollars  ($16.50)
per Share, and (2) the fair market value (as hereinafter defined) of such Shares
as of the date Executive's employment so ceases.

                  (b) The Company may exercise the right and option  provided in
Section  15(a) above by giving  Executive a written  notice of such  election to
purchase  at any time  within  ninety  (90)  days  after  the  date  Executive's
employment  so ceases.  The closing for the  purchase by the Company of any such
Shares  pursuant to the provisions of said Section 15(a) shall take place at the
offices of the Company on the date specified in such written notice,  which date
shall be a  business  day not later  than  sixty  (60) days  after the date such
notice  is  given.  At such  closing,  Executive  will  deliver  or  cause to be
delivered  such Shares,  duly  endorsed  for  transfer,  against  payment of the
applicable  purchase  price  therefor.  Such purchase  price shall be payable to
Executive  in cash or other  immediately  available  funds.  To the  extent  the
Company  chooses not to exercise  such right and option under said Section 15(a)
to purchase any Shares,  such Shares shall  thereupon cease to be subject to the
provisions of this Section 15.

                  (c) For the purposes of this Agreement, "fair market value" of
a Share as of any date shall mean the value of such stock as  determined in good
faith by the Board of  Directors of the Company on a basis  consistent  with the
manner of  determining  the fair market value of the Company's  common stock for
purposes of offering the Company's common stock to equity investors.

         IN WITNESS WHEREOF,  the parties have executed this Agreement as of the
date and year first above written.

<PAGE>


Company or any of its  subsidiaries  or affiliates  which he may then possess or
have under his control.

         3.  COMPENSATION AND RELATED MATTERS.

             (a) BASE SALARY.  Executive shall receive a base salary paid by the
Company  ("Base  Salary") at the annual rate of Four  Hundred  Thousand  Dollars
($400,000) during each calendar year of the Term, payable in substantially equal
monthly  installments  (or such other more  frequent  times as executives of the
Company  normally are paid).  In addition,  the Company's  Board of Directors or
Option and  Compensation  Committee  of the Board of  Directors  shall,  in good
faith,  consider granting  increases in the Base Salary based on such factors as
Executive's  performance and the growth and/or profitability of the Company, but
the Company shall have no obligation to grant such increases in compensation.

             (b) BONUS  PAYMENTS.  Executive  shall be entitled  to receive,  in
addition  to the Base  Salary,  such  bonus  payments,  if any,  as the Board of
Directors or the Option and Compensation Committee of the Board of Directors may
specify.

             (c)  EXPENSES.   During  the  term  of  his  employment  hereunder,
Executive shall be entitled to receive prompt  reimbursement  for all reasonable
expenses  incurred  by him (in  accordance  with  the  policies  and  procedures
established  by the Board of  Directors  for its senior  executive  officers) in
performing  services  hereunder,   provided  that  Executive  properly  accounts
therefor in accordance with Company policy.

             (d) OTHER  BENEFITS.  The Company shall not make any changes in any
employee  benefit  plans or other  arrangements  in effect on the date hereof or
subsequently  in  effect  in  which   Executive   currently  or  in  the  future
participates (including,  without limitation,  each pension and retirement plan,
supplemental pension and retirement plan, savings and profit sharing plan, stock
or unit ownership plan,  stock or unit purchase plan, stock or unit option plan,
life insurance plan,  medical  insurance  plan,  disability  plan,  dental plan,
health-and-accident  plan, or any other similar plan or arrangement)  that would
adversely affect Executive's rights or benefits  thereunder,  unless such change
occurs  pursuant to a program  applicable  to all  executives of the Company and
does not  result in a  proportionately  greater  reduction  in the  rights of or
benefits to  Executive  as compared  with any other  executive  of the  Company.
Executive  shall be entitled to  participate  in or receive  benefits  under any
employee benefit plan or other  arrangement made available by the Company now or
in the future to its senior  executive  officers and key  management  employees,
subject to and on a basis  consistent  with the terms,  conditions,  and overall
administration of such plan or arrangement.  Nothing paid to Executive under any
plan or arrangement presently in effect or made available in the future shall be
deemed  to be in lieu of the  Base  Salary  payable  to  Executive  pursuant  to
paragraph (a) of this Section 3.

             (e)  VACATIONS.  Executive  shall  be  entitled  to ten  (10)  paid
vacation days for the period from the date of this  Agreement  through  December
31, 1999.  Executive shall be entitled to twenty (20) paid vacation days in each
calendar year commencing on or after January 1, 2000, or such additional  number
as may be determined by the Board of Directors  from time to

                                       3

<PAGE>

time.  For purposes of this Section 3(e),  weekends  shall not count as vacation
days and  Executive  shall also be  entitled to all paid  holidays  given by the
Company to its senior executive officers.

             (f)  PERQUISITES.  Executive  shall  be  entitled  to  receive  the
perquisites and fringe benefits appertaining to senior executive officers of the
Company in accordance  with any practice  established by the Board of Directors.
In  the  event  Executive's  employment  hereunder  is  terminated  (whether  by
Executive  or the  Company) for any reason  whatsoever  (other than  Executive's
death), then the Company shall, at Executive's written request and to the extent
permitted by the terms of such policies and applicable law, assign and convey to
Executive any life insurance  policies  maintained by the Company on the life of
Executive,  who shall thereafter be solely responsible,  at his election, to pay
all  premiums  payable  after such  assignment  and  conveyance  to maintain the
coverage under such policies with respect to Executive.  Executive  shall not be
required  to pay any  money or other  consideration  to the  Company  upon  such
assignment  and  conveyance,  it being  acknowledged  and agreed by the  parties
hereto that Executive's  execution and delivery hereof  constitute  adequate and
satisfactory consideration for such assignment and conveyance.

             (g) PRORATION. Excepting only payments pursuant to Section 3(b) for
calendar year 1999 (which  payments  shall be based upon a full calendar  year),
any  payments  or  benefits  payable to  Executive  hereunder  in respect of any
calendar  year during  which  Executive is employed by the Company for less than
the  entire  year,   unless  otherwise   provided  in  the  applicable  plan  or
arrangement,  shall be  prorated in  accordance  with the number of days in such
calendar year during which he is so employed.

      4. EXECUTIVE'S  OFFICE AND RELOCATION.  Executive shall primarily  perform
his duties and  responsibilities  hereunder at the Company's  offices located at
5080 Spectrum Drive, Addison, Texas, and 312 Union Wharf, Boston,  Massachusetts
(or  at  such  other  location   within  the  Dallas,   Texas,   and/or  Boston,
Massachusetts,  metropolitan  areas,  to which  the  Company  may in the  future
relocate such  principal  executive  offices),  except for  reasonable  required
travel on the Company's  business.  If the Company requests  Executive to report
for the performance of his services hereunder on a regular or permanent basis at
any  location  or office  more  than  thirty-five  (35)  miles  from the  office
locations  described  in the first  sentence  of this  Section 4, and  Executive
agrees to such change, the Company shall pay Executive's  reasonable  relocation
and  moving  expenses,  including,  but not  limited  to, the cost of moving his
immediate family,  expenses incurred while seeking new housing (including travel
by Executive's  spouse) and temporary  living expenses  incurred by Executive or
his family for up to one hundred eighty (180) days.

      5. TERMINATION.  Executive's employment hereunder may be terminated by the
Company or Executive, as applicable,  without any breach of this Agreement, only
under the following circumstances.

             (a) DEATH.  Executive's  employment  hereunder shall terminate upon
his death.

<PAGE>

             (b)  DISABILITY.  If, as a result of Executive's  incapacity due to
physical or mental illness,  Executive  shall have been unable,  with reasonable
accommodation,   to  perform  the   essential   functions   of  his  duties  and
responsibilities  hereunder  on a full time basis for one hundred  eighty  (180)
consecutive  calendar  days, and within thirty (30) days after written notice of
termination  is given  (which  may  occur  before  or after  the end of such one
hundred  eighty  (180) day  period)  Executive  shall not have  returned  to the
performance of his material managerial duties and responsibilities  hereunder on
a full time basis, the Company may terminate Executive's employment hereunder.

             For purposes of this  Agreement,  the  termination  of  Executive's
employment  hereunder by Executive  because of the occurrence of any one or more

                  (D) the  relocation  of  Executive's  office at which he is to

                  (C) the  relocation  of  Executive's  office at which he is to
perform his duties and  responsibilities  hereunder to a location outside of the

adverse  alteration in the office space within which Executive is to perform his
duties and  responsibilities  hereunder or in the secretarial and administrative
support provided to Executive; or

                                       6

                  (D) a failure by the Company or any subsidiary or affiliate of

     6.  COMPENSATION  UPON TERMINATION OR FAILURE TO RENEW.  Executive shall be
entitled to the following  compensation from the Company upon the termination of
his  employment or upon the Company's  delivery of notice  pursuant to Section 1
that the Term of this Agreement  shall not following any anniversary of the date
hereof be automatically extended for an additional year.

             (a) DEATH. If Executive's  employment shall be terminated by reason
of his death, the Company shall pay to such person as shall have been designated
in a notice filed with the Company prior to  Executive's  death,  or, if no such
person shall be designated, to his estate as a death benefit, his Base Salary to
the  date  of  his  death  in  addition  to  any  payments  Executive's  spouse,
beneficiaries,  or estate may be entitled to receive  pursuant to any pension or
employee benefit plan or other  arrangement or life insurance policy  maintained
by the Company. In addition,  (x) the Company shall make payments of premiums to
continue the medical and dental  insurance  coverage of  Executive's  spouse and
children  under  age  twenty-five  (25) as in  effect  at and as of the  date of
Executive's  death (or to provide as similar  coverage as possible  for the same
premiums if the continuation of existing  coverage is not permitted) for one (1)
year  after  the date of  Executive's  death,  in each case to the  extent  such
coverage is available, and (y) the Company shall make a lump sum cash payment to
the appropriate  insurance  company(ies)  in an amount  sufficient to fully fund
future premium  payments  pursuant to Executive's  then existing  second-to-die,
split-dollar   insurance   policy(ies)   obtained  through  the  Company  and/or
OccuSystems, Inc.

             (b)  DISABILITY.  During any period that Executive fails to perform
his material  managerial  duties and  responsibilities  hereunder as a result of
incapacity  due to  physical  or mental  illness,  Executive  shall  continue to
receive his Base Salary and any bonus payments until  Executive's  employment is
terminated  pursuant to Section 5(b) hereof or until  Executive  terminates  his
employment  pursuant to Section  5(d)(2) hereof,  whichever first occurs.  After
such termination, the Company shall pay to Executive, on or before the fifth day
following the Date of Termination  (as  hereinafter  defined) his Base Salary to
the Date of  Termination.  In addition,  (x) the Company  shall make payments of
premiums as necessary to cause  Executive  and  Executive's  spouse and children
under age  twenty-five  (25) to continue to be covered by the medical and dental
insurance  as in effect at and as of the Date of  Termination  (or to provide as
similar  coverage  as possible  for the same  premiums  if the  continuation  of
existing  coverage  is not  permitted)  for  one  (1)  year  after  the  Date of
Termination,  in each case to the extent such coverage is available, and (y) the
Company  shall  make a lump  sum  cash  payment  to  the  appropriate  insurance
company(ies)  in an amount  sufficient  to fully fund  future  premium  payments
pursuant to  Executive's  then existing  second-to-die,  split-dollar  insurance
policy(ies) obtained through the Company and/or OccuSystems, Inc.

             (c) CAUSE. If Executive's employment shall be terminated for Cause,
the Company shall pay Executive his Base Salary  through the Date of Termination
at the rate in

                                       7

<PAGE>

effect at  the  time Notice of Termination  is given.  Such payments shall fully
discharge the Company's obligations hereunder.

             (d) BREACH BY THE  COMPANY,  FOR GOOD  REASON,  OR UPON  FAILURE TO
RENEW.  If  (1) in  breach  of  this  Agreement,  the  Company  shall  terminate
Executive's  employment  (it being  understood  that a purported  termination of
Executive's  employment  by the  Company  pursuant  to  any  provision  of  this
Agreement that is disputed and finally  determined not to have been proper shall
be a termination by the Company in breach of this  Agreement),  or (2) Executive
shall  terminate his employment  for Good Reason,  or (3) the Company shall give
Executive  notice  pursuant  to Section 1 prior to any  anniversary  of the date
hereof that the Term of this Agreement shall not be  automatically  extended for
an  additional  year on any such  anniversary  date,  then the Company shall pay
Executive:

                  (A) his Base  Salary  through the Date of  Termination  at the
rate in effect at the time Notice of Termination is given;

                  (B) in lieu of any further  salary  payments to Executive  for
periods  subsequent  to the  Date  of  Termination,  the  Company  shall  pay as
severance  pay to  Executive  on or before the fifth day  following  the Date of
Termination  and on the  fifth  day of  each  of the  twenty-three  (23)  months
thereafter (amounting to a total of twelve (24) months), an amount in cash equal
one-twelfth  (1/12) of  Executive's  annual Base Salary at the rate in effect at
the time the Notice of  Termination is given (for a total of two (2) year's Base
Salary); and

                  (C) all  benefits  payable  under  the  terms of any  employee
benefit plan or other arrangement as of the Date of Termination.

             In  addition,  (x) the Company  shall make  payments of premiums as
necessary to cause  Executive  and  Executive's  spouse and  children  under age
twenty-five  (25) to continue to be covered by the medical and dental  insurance
as in effect at and as of the Date of  Termination  (or to  provide  as  similar
coverage  as possible  for the same  premiums  if the  continuation  of existing
coverage is not  permitted) for one (1) year after the Date of  Termination,  in
each case to the extent such  coverage is  available,  and (y) the Company shall
make a lump sum cash payment to the  appropriate  insurance  company(ies)  in an
amount  sufficient to fully fund future premium payments pursuant to Executive's
then existing second-to-die, split-dollar insurance policy(ies) obtained through
the Company and/or OccuSystems, Inc.

             (e)  MITIGATION.  Executive  shall not be required to mitigate  the
amount of any payment provided for in this Section 6 by seeking other employment
or  otherwise;   PROVIDED,  HOWEVER,  that,  anything  herein  to  the  contrary
notwithstanding, in the event of the termination of Executive's employment prior
to a Change in Control (as defined in the  Concentra  Managed Care,  Inc.,  1997
Long-Term  Incentive Plan) which occurs after the consummation of the Merger (as
defined in that certain Amended and Restated Agreement and Plan of Merger, dated
as of March 24,  1999,  by and  between  Yankee  Acquisition  Corp.,  a Delaware
corporation,  and the Company)  (but not if  Executive's  employment  terminates
after such a Change in Control),  the amount of any payment  pursuant to Section
6(d)(B) and/or  pursuant to the first paragraph of

                                       8

<PAGE>

Section  6(f) shall be reduced by any  compensation  earned by  Executive as the
result of  employment  by another  employer  (whether  as a  director,  officer,
employee,  manager,  owner,  consultant,   independent  contractor,  advisor  or
otherwise) after the Date of Termination  until the end of the twenty-four month
period of clause (B) of Section 6(d) above.

             (f) ADDITIONAL  REASON. If Executive shall terminate his employment
for Additional Reason, as well as for Good Reason,  then, in addition to and not
in lieu of any  other  amounts  payable  by the  Company  to  Executive  whether
pursuant to Section  6(d) or  otherwise  (it being the  intention of the parties
that,  upon the occurrence of an event or events  described in the definition or
"Good Reason" and "Additional  Reason" in Section 5(d),  Executive may terminate
this  Agreement  for Good Reason AND for  Additional  Reason),  then the Company
shall pay  Executive  as  additional  severance  pay, on or before the fifth day
following the Date of Termination, a lump sum in cash equal to one-half (1/2) of
Executive's  annual  Base Salary at the rate in effect at the time the Notice of
Termination is given (for a total of two and one-half (2 1/2) times  Executive's
full annual Base Salary when combined with amounts  payable  pursuant to Section
6(d)(B)).

             In  addition,  the  Company  shall make  payments  of  premiums  as
necessary to cause  Executive  and  Executive's  spouse and  children  under age
twenty-five  (25) to continue to be covered by the medical and dental  insurance
as in effect at and as of the Date of  Termination  (or to  provide  as  similar
coverage  as possible  for the same  premiums  if the  continuation  of existing
coverage  is not  permitted)  for one (1) year in  addition  to the one (1) year
provided for under Section 6(d) (for a total of two (2) years) after the Date of
Termination, in each case to the extent such coverage is available.

         7.  OTHER PROVISIONS RELATING TO TERMINATION.

             (a)  NOTICE  OF   TERMINATION.   Any   termination  of  Executive's
employment by the Company or by Executive (other than termination because of the
death of Executive)  shall be  communicated  by written Notice of Termination to
the  other  party  hereto.  For  purposes  of  this  Agreement,   a  "Notice  of
Termination"  shall mean a notice which shall indicate the specific  termination
provision in this Agreement relied upon and shall set forth in reasonable detail
the facts and  circumstances  claimed  to  provide  a basis for  termination  of
Executive's employment under the provision so indicated.

             (b) DATE OF TERMINATION.  For purposes of this Agreement,  "Date of
Termination"  shall mean:  (1) if  Executive's  employment  is terminated by his
death,  the date of his  death;  (2) if  Executive's  employment  is  terminated
because of a disability  pursuant to Section  5(b),  then thirty (30) days after
Notice of Termination is given  (provided that Executive shall not have returned
to the  performance  of his duties on a full-time  basis during such thirty (30)
day period);  (3) if  Executive's  employment  is  terminated by the Company for
Cause or by  Executive  for Good  Reason  and/or for  Additional  Reason,  then,
subject  to  Sections  7(c)  and  7(d),  the date  specified  in the  Notice  of
Termination;  (4) if the Company gives  Executive  notice  pursuant to Section 1
prior to any  anniversary  of the date  hereof  that the Term of this  Agreement
shall  not  be  automatically  extended  for an  additional  year  on  any  such
anniversary  date, the date upon which

                                       9

<PAGE>

the Term expires;  and (5) if Executive's employment is terminated for any other
reason,  the date on which a Notice of Termination is given.

             (c) GOOD REASON AND/OR ADDITIONAL REASON. Upon the occurrence of an
event described in clauses (A) through (E) of the definition of "Good Reason" in
Section 5(d),  and/or upon the  occurrence of an event  described in clauses (A)
through (D) of the definition of "Additional Reason" in Section 5(d),  Executive
may terminate his employment hereunder for Good Reason and/or Additional Reason,
as  applicable,  within one hundred  eighty  (180) days  thereafter  by giving a
Notice of  Termination  to the  Company  to that  effect.  If the  effect of the
occurrence  of the event  giving rise to Good Reason  and/or  Additional  Reason
under Section 5(d) may be cured,  the Company shall have the opportunity to cure
any  such  effect  for a  period  of  thirty  (30)  days  following  receipt  of
Executive's Notice of Termination. If the Company fails to cure any such effect,
the termination for Good Reason and/or  Additional Reason shall become effective
on the date specified in Executive's  Notice of  Termination.  If Executive does
not give such Notice of  Termination  to the Company,  then this  Agreement will
remain in effect; PROVIDED,  HOWEVER, that the failure of Executive to terminate
this  Agreement for Good Reason and/or  Additional  Reason shall not be deemed a
waiver of  Executive's  right to terminate his employment for Good Reason and/or
Additional Reason upon the occurrence of a subsequent event described in Section
5(d) in accordance with the terms of this Agreement.

             (d) CAUSE.  In the case of any  termination of Executive for Cause,
the Company will give Executive a Notice of Termination describing in reasonable
detail, the facts or circumstances giving rise to Executive's  termination (and,
if  applicable,  the action  required  to cure same) and will  permit  Executive
thirty  (30)  days  to cure  such  failure  to  comply  or  perform.  Cause  for
Executive's  termination will not be deemed to exist until the expiration of the
foregoing  cure period,  so long as Executive  continues to use his best efforts
during  the cure  period  to cure  such  failure.  If  within  thirty  (30) days
following  Executive's  receipt of a Notice of Termination for Cause,  Executive
has not cured the facts or circumstances giving rise to Executive's  termination
for Cause,  then Executive's  termination for Cause shall be effective as of the
date specified in the Notice of Termination.

             (e) INTEREST.  Until paid, all past due amounts required to be paid
by the Company under any provision of this Agreement  shall bear interest at the
highest non-usurious rate permitted by applicable federal, state, or local law.

        8. SUCCESSORS; BINDING AGREEMENT.

             (a) SUCCESSORS.  This Agreement shall be binding upon, and inure to
the  benefit  of,  the  Company,  Executive,  and their  respective  successors,
assigns, personal and legal representatives,  executors, administrators,  heirs,
distributees, devisees, and legatees, as applicable.

             (b)  ASSUMPTION.  The Company will require any  successor  (whether
direct or indirect, by purchase of securities,  merger,  consolidation,  sale of
assets,  or otherwise) to all or substantially  all of the business or assets of
the Company,  by an agreement in form and substance

                                       10

<PAGE>

reasonably  satisfactory to Executive, to expressly assume this Agreement and to
agree to perform  this  Agreement in the same manner and to the same extent that
the  Company  would be required  to perform it if no such  succession  had taken
place.   Failure  of  the  Company  to  obtain  such  agreement   prior  to  the
effectiveness  of any such  succession  shall be a breach of this  Agreement and
shall entitle  Executive to compensation from the Company in the same amount and
on the same terms as he would be  entitled to  hereunder  if he  terminated  his
employment for Good Reason (and, if such  succession  occurs on or before August
17,  2000,  in the same  amount and on the same terms as he would be entitled to
hereunder if he terminated his employment  for Additional  Reason),  except that
for  purposes  of  implementing  the  foregoing,  the  date on  which  any  such
succession becomes effective shall be deemed the Date of Termination.

             (c) CERTAIN  PAYMENTS.  If  Executive  should die while any amounts
would still be payable to him  hereunder if he had  continued to live,  all such
amounts,  unless otherwise provided herein, shall be paid in accordance with the
terms of this Agreement to Executive's  devisee,  legatee, or other designee or,
if there be no such designee, to Executive's estate.

     9.  NOTICE.  For  purposes  of this  Agreement,  all  notices and all other
communications  provided for in this Agreement  shall be in writing and shall be
deemed  to have been  duly  given  when (a)  delivered  personally,  (b) sent by
facsimile or similar electronic device and confirmed, (c) delivered by overnight
express, or (d) if sent by any other means, upon receipt.  Notices and all other
communications provided for in this Agreement shall be addressed as follows:

                  If to Executive:

or to such other  address  as either  party may have  furnished  to the other in
writing in accordance herewith.

         10.  MISCELLANEOUS.  No  provision of this  Agreement  may be modified,
waived, or discharged unless such waiver,  modification,  or discharge is agreed
to in a written  instrument  signed by Executive  and the Company.  No waiver by
either party hereto of, or compliance  with,  any condition or provision of this
Agreement  to be  performed  by such  other  party  shall be  deemed a waiver of
similar or  dissimilar  provisions  or conditions at the same or at any prior or
subsequent time. No agreements or representations, oral or otherwise, express or
implied,  with  respect to the  subject  matter  hereof have been made by either
party  which  are not set  forth  expressly  in this  Agreement.  The  validity,
interpretation,  construction,  and  performance  of  this  Agreement  shall  be
governed  by the laws of the  State of  Delaware,  excluding  any  choice-of-law
provisions thereof.

connection  with  the  resolution  of any  dispute  or  controversy  under or in
connection  with this Agreement  shall be reimbursed by the Company to Executive
as bills for such  services are  presented  by Executive to the Company,  unless
such dispute or  controversy  is found to have been brought not in good faith or
without merit by a court of competent jurisdiction.

         12. VALIDITY.  The invalidity or  unenforceability  of any provision or
provisions of this Agreement shall not affect the validity or  enforceability of
any other  provision  of this  Agreement,  which shall  remain in full force and
effect.

         13.   COUNTERPARTS.   This   Agreement   may  be  executed  in  several
counterparts,  each of which shall be deemed to be an original, but all of which

that certain  Amended and  Restated  Agreement  and Plan of Merger,  dated as of
March 24, 1999, by and between Yankee Acquisition Corp., a Delaware corporation,
and the Company,  as such agreement may be amended from time to time); upon such
consummation,  this Agreement shall be in full force and effect.  This Agreement
constitutes the entire agreement between the parties with respect to the subject
matter  hereof  and  supersedes  in all  respects  any and all prior  employment
agreements  and/or severance  protection  letters,  agreements,  or arrangements
between Executive,  on the one hand, and the Company or any other predecessor in
interest  thereto or any of their  respective  subsidiaries,  on the other hand,
which  prior  employment   agreements  and/or  severance   protection   letters,
agreements,  and  arrangements,  if any, are hereby  cancelled and of no further
force or effect.

         15. RIGHT AND OPTION OF COMPANY TO REPURCHASE  SHARES UPON  TERMINATION
OF EMPLOYMENT.

                  (a) In the event that,  prior to an initial public offering of

shall thereupon have the right and option,  but not the obligation,  to purchase
from Executive all or any part of the shares of common stock, par value $.01 per
share,  of  the  Company  (the  "Shares")  held  by  Executive  as of  the  date
Executive's employment so ceases at a purchase price equal to the greater of (1)
Sixteen and 50/100 Dollars ($16.50) per Share, and (2) the fair market value (as
hereinafter  defined) of such Shares as of the date  Executive's  employment  so
ceases.

             (b) The  Company  may  exercise  the right and option  provided  in
Section  15(a) above by giving  Executive a written  notice of such  election to
purchase  at any time  within  ninety  (90)  days  after  the  date  Executive's
employment  so ceases.  The closing for the  purchase by the Company of any such
Shares  pursuant to the provisions of said Section 15(a) shall take place at the

delivered  such Shares,  duly  endorsed  for  transfer,  against  payment of the
applicable  purchase  price  therefor.  Such purchase  price shall be payable to
Executive  in cash or other  immediately  available  funds.  To the  extent  the
Company  chooses not to exercise  such right and option under said Section 15(a)

provisions of this Section 15.

             (c) For the purposes of this  Agreement,  "fair market  value" of a
Share as of any date shall mean the value of such  stock as  determined  in good
faith by the Board of  Directors of the Company on a basis  consistent  with the
manner of  determining  the fair market value of the Company's  common stock for
purposes of offering the Company's common stock to equity investors.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
and year first above written.

<PAGE>


Company or any of its subsidiaries or affiliates which he may then possess or
have under his control.

     3.   COMPENSATION AND RELATED MATTERS.

          (a)  BASE SALARY. Executive shall receive a base salary paid by the
Company ("Base Salary") at the annual rate of Two Hundred Twenty-Five Thousand
Dollars ($225,000) during each calendar year of the Term, payable in
substantially equal monthly installments (or such other more frequent times as
executives of the Company normally are paid). In addition, the Company's Board
of Directors or Option and Compensation Committee of the Board of Directors
shall, in good faith, consider granting increases in the Base Salary based on
such factors as Executive's performance and the growth and/or profitability of
the Company, but the Company shall have no obligation to grant such increases in
compensation.

          (b)  BONUS PAYMENTS. Executive shall be entitled to receive, in
addition to the Base Salary, such bonus payments, if any, as the Board of
Directors or the Option and Compensation Committee of the Board of Directors may
specify.

          (c)  EXPENSES. During the term of his employment hereunder, Executive
shall be entitled to receive prompt reimbursement for all reasonable expenses
incurred by him (in accordance with the policies and procedures established by
the Board of Directors for its senior executive officers) in performing services
hereunder, provided that Executive properly accounts therefor in accordance with
Company policy.

          (d)  OTHER BENEFITS. The Company shall not make any changes in any
employee benefit plans or other arrangements in effect on the date hereof or
subsequently in effect in which Executive currently or in the future
participates (including, without limitation, each pension and retirement plan,
supplemental pension and retirement plan, savings and profit sharing plan, stock
or unit ownership plan, stock or unit purchase plan, stock or unit option plan,
life insurance plan, medical insurance plan, disability plan, dental plan,
health-and-accident plan, or any other similar plan or arrangement) that would
adversely affect Executive's rights or benefits thereunder, unless such change
occurs pursuant to a program applicable to all executives of the Company and
does not result in a proportionately greater reduction in the rights of or
benefits to Executive as compared with any other executive of the Company.
Executive shall be entitled to participate in or receive benefits under any
employee benefit plan or other arrangement made available by the Company now or
in the future to its senior executive officers and key management employees,
subject to and on a basis consistent with the terms, conditions, and overall
administration of such plan or arrangement. Nothing paid to Executive under any
plan or arrangement presently in effect or made available in the future shall be
deemed to be in lieu of the Base Salary payable to Executive pursuant to
paragraph (a) of this Section 3.

          (e)  VACATIONS. Executive shall be entitled to ten (10) paid vacation
days for the period from the date of this Agreement through December 31, 1999.
Executive shall be entitled to twenty (20) paid vacation days in each calendar
year commencing on or after January 1, 2000, or such additional number as may be
determined by the Board of Directors from time to


                                       3
<PAGE>


time. For purposes of this Section 3(e), weekends shall not count as vacation
days and Executive shall also be entitled to all paid holidays given by the
Company to its senior executive officers.

          (f)  PERQUISITES. Executive shall be entitled to receive the
perquisites and fringe benefits appertaining to senior executive officers of the
Company in accordance with any practice established by the Board of Directors.
In the event Executive's employment hereunder is terminated (whether by
Executive or the Company) for any reason whatsoever (other than Executive's
death), then the Company shall, at Executive's written request and to the extent
permitted by the terms of such policies and applicable law, assign and convey to
Executive any life insurance policies maintained by the Company on the life of
Executive, who shall thereafter be solely responsible, at his election, to pay
all premiums payable after such assignment and conveyance to maintain the
coverage under such policies with respect to Executive. Executive shall not be
required to pay any money or other consideration to the Company upon such
assignment and conveyance, it being acknowledged and agreed by the parties
hereto that Executive's execution and delivery hereof constitute adequate and
satisfactory consideration for such assignment and conveyance.

          (g)  PRORATION. Excepting only payments pursuant to Section 3(b) for
calendar year 1999 (which payments shall be based upon a full calendar year),
any payments or benefits payable to Executive hereunder in respect of any
calendar year during which Executive is employed by the Company for less than
the entire year, unless otherwise provided in the applicable plan or
arrangement, shall be prorated in accordance with the number of days in such
calendar year during which he is so employed.

     4.   EXECUTIVE'S OFFICE AND RELOCATION. Executive shall primarily perform
his duties and responsibilities hereunder at the Company's offices located at
5080 Spectrum Drive, Addison, Texas, and 312 Union Wharf, Boston, Massachusetts
(or at such other location within the Dallas, Texas, and Boston, Massachusetts,
metropolitan areas, to which the Company may in the future relocate such
principal executive offices), except for reasonable required travel on the
Company's business. If the Company requests Executive to report for the
performance of his services hereunder on a regular or permanent basis at any
location or office more than thirty-five (35) miles from the office locations
described in the first sentence of this Section 4, and Executive agrees to such
change, the Company shall pay Executive's reasonable relocation and moving
expenses, including, but not limited to, the cost of moving his immediate
family, expenses incurred while seeking new housing (including travel by
Executive's spouse) and temporary living expenses incurred by Executive or his
family for up to one hundred eighty (180) days.

     5.   TERMINATION. Executive's employment hereunder may be terminated by the
Company or Executive, as applicable, without any breach of this Agreement, only
under the following circumstances.

          (a)  DEATH. Executive's employment hereunder shall terminate upon his
death.

physical or mental illness, Executive shall have been unable, with reasonable
accommodation, to perform the essential functions of his duties and
responsibilities hereunder on a full time basis for one hundred eighty (180)
consecutive calendar days, and within thirty (30) days after written notice of
termination is given (which may occur before or after the end of such one
hundred eighty (180) day period) Executive shall not have returned to the
performance of his material managerial duties and responsibilities hereunder on
a full time basis, the Company may terminate Executive's employment hereunder.

          (c)  CAUSE. Subject to the provisions of Section 7(d), the Company may
terminate Executive's employment hereunder for Cause. For purposes of this
Agreement, the Company shall have "Cause" to terminate Executive's employment
hereunder upon:

               (1)  Executive's willful or intentional failure to perform or
gross negligence in the performance of Executive's material duties and
responsibilities hereunder (other than any such failure resulting from
Executive's incapacity due to physical or mental illness or any such actual or
anticipated failure after the issuance of a Notice of Termination for Good
Reason (as hereinafter defined) by Executive);

               (2)  The commission by Executive of dishonesty or fraud of a
material nature in connection with the performance of his duties hereunder, or

               (3)  The conviction of Executive, or the entering of a plea of
nolo contendere by Executive, with respect to a felony;

               (4)  Unprofessional or unethical conduct of a material nature by
Executive in connection with the performance of his duties hereunder as
determined in a final adjudication of any board, institution, organization or
governmental agency having any privilege or right to pass upon the conduct of
Executive;

               (5)  Intentional, willful, or grossly negligent conduct by
Executive which is materially detrimental to the reputation, character,
business, or standing of the Company, including, without limitation, the use by
Executive of a controlled substance; or

               (6)  The continued breach by Executive of any of Executive's
material obligations under this Agreement.

          (d)  TERMINATION BY EXECUTIVE. Subject to the provisions of Section
7(c), and at his option, Executive may terminate his employment hereunder (1)
for Good Reason and/or for Additional Reason, or (2) if his health should become

          For purposes of this Agreement, the termination of Executive's

               (D)  a failure by the Company or any subsidiary or affiliate of
the Company to comply with any other material term or provision hereof or of any
other written agreement between Executive and the Company or any such subsidiary
or affiliate.

     6.   COMPENSATION UPON TERMINATION OR FAILURE TO RENEW. Executive shall be
entitled to the following compensation from the Company upon the termination of
his employment or upon the Company's delivery of notice pursuant to Section 1
that the Term of this Agreement shall not following any anniversary of the date
hereof be automatically extended for an additional year.

          (a)  DEATH. If Executive's employment shall be terminated by reason of
his death, the Company shall pay to such person as shall have been designated in
a notice filed with the Company prior to Executive's death, or, if no such
person shall be designated, to his estate as a death benefit, his Base Salary to

employee benefit plan or other arrangement or life insurance policy maintained
by the Company. In addition, (x) the Company shall make payments of premiums to
continue the medical and dental insurance coverage of Executive's spouse and
children under age twenty-five (25) as in effect at and as of the date of
Executive's death (or to provide as similar coverage as possible for the same
premiums if the continuation of existing coverage is not permitted) for one (1)
year after the date of Executive's death, in each case to the extent such
coverage is available, and (y) the Company shall make a lump sum cash payment to
the appropriate insurance company(ies) in an amount sufficient to fully fund
future premium payments pursuant to Executive's then existing second-to-die,
split-dollar insurance policy(ies) obtained through the Company, if any.

          (b)  DISABILITY. During any period that Executive fails to perform his
material managerial duties and responsibilities hereunder as a result of
incapacity due to physical or mental illness, Executive shall continue to
receive his Base Salary and any bonus payments until Executive's employment is
terminated pursuant to Section 5(b) hereof or until Executive terminates his
employment pursuant to Section 5(d)(2) hereof, whichever first occurs. After
such termination, the Company shall pay to Executive, on or before the fifth day
following the Date of Termination (as hereinafter defined) his Base Salary to
the Date of Termination. In addition, (x) the Company shall make payments of
premiums as necessary to cause Executive and Executive's spouse and children
under age twenty-five (25) to continue to be covered by the medical and dental
insurance as in effect at and as of the Date of Termination (or to provide as
similar coverage as possible for the same premiums if the continuation of
existing coverage is not permitted) for one (1) year after the Date of
Termination, in each case to the extent such coverage is available, and (y) the
Company shall make a lump sum cash payment to the appropriate insurance
company(ies) in an amount sufficient to fully fund future premium payments
pursuant to Executive's then existing second-to-die, split-dollar insurance
policy(ies) obtained through the Company, if any.

          (c)  CAUSE. If Executive's employment shall be terminated for Cause,
the Company shall pay Executive his Base Salary through the Date of Termination
at the rate in


                                       7
<PAGE>


effect at the time Notice of Termination is given. Such payments shall fully
discharge the Company's obligations hereunder.

          (d)  BREACH BY THE COMPANY, FOR GOOD REASON, OR UPON FAILURE TO RENEW.
If (1) in breach of this Agreement, the Company shall terminate Executive's
employment (it being understood that a purported termination of Executive's
employment by the Company pursuant to any provision of this Agreement that is
disputed and finally determined not to have been proper shall be a termination
by the Company in breach of this Agreement), or (2) Executive shall terminate
his employment for Good Reason, or (3) the Company shall give Executive notice
pursuant to Section 1 prior to any anniversary of the date hereof that the Term
of this Agreement shall not be automatically extended for an additional year on
any such anniversary date, then the Company shall pay Executive:

               (A)  his Base Salary through the Date of Termination at the rate
in effect at the time Notice of Termination is given;

               (B)  in lieu of any further salary payments to Executive for
periods subsequent to the Date of Termination, the Company shall pay as
severance pay to Executive on or before the fifth day following the Date of
Termination and on the fifth day of each of the eleven (11) months thereafter
(amounting to a total of twelve (12) months), an amount in cash equal
one-twelfth (1/12) of Executive's annual Base Salary at the rate in effect at
the time the Notice of Termination is given; and

               (C)  all benefits payable under the terms of any employee benefit
plan or other arrangement as of the Date of Termination.

          In addition, (x) the Company shall make payments of premiums as
necessary to cause Executive and Executive's spouse and children under age
twenty-five (25) to continue to be covered by the medical and dental insurance
as in effect at and as of the Date of Termination (or to provide as similar
coverage as possible for the same premiums if the continuation of existing
coverage is not permitted) for one (1) year after the Date of Termination, in
each case to the extent such coverage is available, and (y) the Company shall
make a lump sum cash payment to the appropriate insurance company(ies) in an
amount sufficient to fully fund future premium payments pursuant to Executive's
then existing second-to-die, split-dollar insurance policy(ies) obtained through
the Company, if any.

          (e)  MITIGATION. Executive shall not be required to mitigate the
amount of any payment provided for in this Section 6 by seeking other employment
or otherwise; PROVIDED, HOWEVER, that, anything herein to the contrary
notwithstanding, in the event of the termination of Executive's employment prior
to a Change in Control (as defined in the Concentra Managed Care, Inc., 1997
Long-Term Incentive Plan) which occurs after the consummation of the Merger (as
defined in that certain Amended and Restated Agreement and Plan of Merger, dated
as of March 24, 1999, by and between Yankee Acquisition Corp., a Delaware
corporation, and the Company) (but not if Executive's employment terminates
after such a Change in Control), the amount of any payment pursuant to Section
6(d)(B) and/or pursuant to the first paragraph of


                                       8
<PAGE>


Section 6(f) shall be reduced by any compensation earned by Executive as the
result of employment by another employer (whether as a director, officer,
employee, manager, owner, consultant, independent contractor, advisor or
otherwise) after the Date of Termination until the end of the twelve month
period of clause (B) of Section 6(d) above.

          (f)  ADDITIONAL REASON. If Executive shall terminate his employment
for Additional Reason, as well as for Good Reason, then, in addition to and not
in lieu of any other amounts payable by the Company to Executive whether
pursuant to Section 6(d) or otherwise (it being the intention of the parties
that, upon the occurrence of an event or events described in the definition or
"Good Reason" and "Additional Reason" in Section 5(d), Executive may terminate
this Agreement for Good Reason AND for Additional Reason), then the Company
shall pay Executive as additional severance pay, on or before the fifth day
following the Date of Termination, a lump sum in cash equal to Executive's full
annual Base Salary at the rate in effect at the time the Notice of Termination
is given (for a total of two (2) times Executive's full annual Base Salary when
combined with amounts payable pursuant to Section 6(d)(B)).

          In addition, the Company shall make payments of premiums as necessary
to cause Executive and Executive's spouse and children under age twenty-five
(25) to continue to be covered by the medical and dental insurance as in effect
at and as of the Date of Termination (or to provide as similar coverage as
possible for the same premiums if the continuation of existing coverage is not
permitted) for one (1) year in addition to the one (1) year provided for under
Section 6(d) (for a total of two (2) years) after the Date of Termination, in
each case to the extent such coverage is available.

     7.   OTHER PROVISIONS RELATING TO TERMINATION.

          (a)  NOTICE OF TERMINATION. Any termination of Executive's employment
by the Company or by Executive (other than termination because of the death of
Executive) shall be communicated by written Notice of Termination to the other
party hereto. For purposes of this Agreement, a "Notice of Termination" shall
mean a notice which shall indicate the specific termination provision in this
Agreement relied upon and shall set forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of Executive's
employment under the provision so indicated.

          (b)  DATE OF TERMINATION. For purposes of this Agreement, "Date of
Termination" shall mean: (1) if Executive's employment is terminated by his
death, the date of his death; (2) if Executive's employment is terminated
because of a disability pursuant to Section 5(b), then thirty (30) days after
Notice of Termination is given (provided that Executive shall not have returned
to the performance of his duties on a full-time basis during such thirty (30)
day period); (3) if Executive's employment is terminated by the Company for
Cause or by Executive for Good Reason and/or for Additional Reason, then,
subject to Sections 7(c) and 7(d), the date specified in the Notice of
Termination; (4) if the Company gives Executive notice pursuant to Section 1
prior to any anniversary of the date hereof that the Term of this Agreement
shall not be automatically extended for an additional year on any such
anniversary date, the date upon which


                                       9
<PAGE>


the Term expires; and (5) if Executive's employment is terminated for any other
reason, the date on which a Notice of Termination is given.

          (c)  GOOD REASON AND/OR ADDITIONAL REASON. Upon the occurrence of an
event described in clauses (A) through (E) of the definition of "Good Reason" in
Section 5(d), and/or upon the occurrence of an event described in clauses (A)
through (D) of the definition of "Additional Reason" in Section 5(d), Executive
may terminate his employment hereunder for Good Reason and/or Additional Reason,
as applicable, within one hundred eighty (180) days thereafter by giving a
Notice of Termination to the Company to that effect. If the effect of the
occurrence of the event giving rise to Good Reason and/or Additional Reason
under Section 5(d) may be cured, the Company shall have the opportunity to cure
any such effect for a period of thirty (30) days following receipt of
Executive's Notice of Termination. If the Company fails to cure any such effect,
the termination for Good Reason and/or Additional Reason shall become effective
on the date specified in Executive's Notice of Termination. If Executive does
not give such Notice of Termination to the Company, then this Agreement will
remain in effect; PROVIDED, HOWEVER, that the failure of Executive to terminate
this Agreement for Good Reason and/or Additional Reason shall not be deemed a
waiver of Executive's right to terminate his employment for Good Reason and/or
Additional Reason upon the occurrence of a subsequent event described in Section
5(d) in accordance with the terms of this Agreement.

          (d)  CAUSE. In the case of any termination of Executive for Cause, the
Company will give Executive a Notice of Termination describing in reasonable
detail, the facts or circumstances giving rise to Executive's termination (and,
if applicable, the action required to cure same) and will permit Executive
thirty (30) days to cure such failure to comply or perform. Cause for
Executive's termination will not be deemed to exist until the expiration of the
foregoing cure period, so long as Executive continues to use his best efforts
during the cure period to cure such failure. If within thirty (30) days
following Executive's receipt of a Notice of Termination for Cause, Executive
has not cured the facts or circumstances giving rise to Executive's termination
for Cause, then Executive's termination for Cause shall be effective as of the
date specified in the Notice of Termination.

          (e)  INTEREST. Until paid, all past due amounts required to be paid by
the Company under any provision of this Agreement shall bear interest at the
highest non-usurious rate permitted by applicable federal, state, or local law.

     8.   SUCCESSORS; BINDING AGREEMENT.

          (a)  SUCCESSORS. This Agreement shall be binding upon, and inure to
the benefit of, the Company, Executive, and their respective successors,
assigns, personal and legal representatives, executors, administrators, heirs,
distributees, devisees, and legatees, as applicable.

          (b)  ASSUMPTION. The Company will require any successor (whether
direct or indirect, by purchase of securities, merger, consolidation, sale of
assets, or otherwise) to all or substantially all of the business or assets of
the Company, by an agreement in form and substance


                                       10
<PAGE>


reasonably satisfactory to Executive, to expressly assume this Agreement and to
agree to perform this Agreement in the same manner and to the same extent that
the Company would be required to perform it if no such succession had taken
place. Failure of the Company to obtain such agreement prior to the
effectiveness of any such succession shall be a breach of this Agreement and
shall entitle Executive to compensation from the Company in the same amount and
on the same terms as he would be entitled to hereunder if he terminated his
employment for Good Reason (and, if such succession occurs on or before August
17, 2000, in the same amount and on the same terms as he would be entitled to
hereunder if he terminated his employment for Additional Reason), except that
for purposes of implementing the foregoing, the date on which any such
succession becomes effective shall be deemed the Date of Termination.

          (c)  CERTAIN PAYMENTS. If Executive should die while any amounts would
still be payable to him hereunder if he had continued to live, all such amounts,
unless otherwise provided herein, shall be paid in accordance with the terms of
this Agreement to Executive's devisee, legatee, or other designee or, if there
be no such designee, to Executive's estate.

     9.   NOTICE. For purposes of this Agreement, all notices and all other

certain Amended and Restated Agreement and Plan of Merger, dated as of March 24,
1999, by and between Yankee Acquisition Corp., a Delaware corporation, and the
Company, as such agreement may be amended from time to time); upon such
consummation, this Agreement shall be in full force and effect. This Agreement

matter hereof and supersedes in all respects any and all prior employment
agreements and/or severance protection letters, agreements, or arrangements
between Executive, on the one hand, and the Company or any other predecessor in
interest thereto or any of their respective subsidiaries, on the other hand,
which prior employment agreements and/or severance protection letters,
agreements, and arrangements, if any, are hereby cancelled and of no further
force or effect.

     15.  RIGHT AND OPTION OF COMPANY TO REPURCHASE SHARES UPON TERMINATION OF
EMPLOYMENT.

          (a)  In the event that, prior to an initial public offering of the
Company's equity securities, Executive's employment with the Company is
terminated for any reason, the Company


                                       12
<PAGE>


shall thereupon have the right and option, but not the obligation, to purchase
from Executive all or any part of the shares of common stock, par value $.01 per
share, of the Company (the "Shares") held by Executive as of the date
Executive's employment so ceases at a purchase price equal to the greater of (1)
Sixteen and 50/100 Dollars ($16.50) per Share, and (2) the fair market value (as
hereinafter defined) of such Shares as of the date Executive's employment so
ceases.

          (b)  The Company may exercise the right and option provided in Section
15(a) above by giving Executive a written notice of such election to purchase at
any time within ninety (90) days after the date Executive's employment so
ceases. The closing for the purchase by the Company of any such Shares pursuant
to the provisions of said Section 15(a) shall take place at the offices of the
Company on the date specified in such written notice, which date shall be a
business day not later than sixty (60) days after the date such notice is given.
At such closing, Executive will deliver or cause to be delivered such Shares,
duly endorsed for transfer, against payment of the applicable purchase price
therefor. Such purchase price shall be payable to Executive in cash or other
immediately available funds. To the extent the Company chooses not to exercise
such right and option under said Section 15(a) to purchase any Shares, such
Shares shall thereupon cease to be subject to the provisions of this Section 15.

          (c)  For the purposes of this Agreement, "fair market value" of a
Share as of any date shall mean the value of such stock as determined in good
faith by the Board of Directors of the Company on a basis consistent with the
manner of determining the fair market value of the Company's common stock for
purposes of offering the Company's common stock to equity investors.

          IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date and year first above written.

        AGREEMENT. THE HOLDER OF THIS CERTIFICATE, BY ACCEPTANCE OF THIS
        CERTIFICATE, AGREES TO BE BOUND BY ALL OF THE PROVISIONS OF SUCH
        STOCKHOLDERS AGREEMENT."

The Legend will be removed by the Company by the delivery of substitute
certificates without such Legend in the event of (i) a Transfer permitted by
this Agreement and in which the Transferee is not required to enter into an
Assumption Agreement or (ii) the termination of Section II pursuant to the terms
hereof.

               (4) TRANSFERS TO PERMITTED TRANSFEREES. The Stockholders and
their Permitted Transferees may Transfer, for no more than cost, any or all of
the shares of Company Capital Stock or, on or after the Debenture Sale, Warrants
held by any of them to any Designated Affiliate who duly executes and delivers
an Assumption Agreement; PROVIDED that in connection therewith the Company, if
it so requests promptly following its receipt of such Assumption Agreement (and,
in such event, such Assumption Agreement shall not be effective unless and until
this proviso has been satisfied), has been furnished with an opinion in form and
substance reasonably satisfactory to the Company of counsel reasonably
satisfactory to the Company that such Transfer is exempt from or not subject to
the provisions of Section 5 of the Securities Act and any other applicable
securities laws; and, PROVIDED, FURTHER, that no Transfer under this Section
II(4) shall be permitted if such Transfer would require the Company to register
a class of equity securities under Section 12 of the Exchange Act under
circumstances where the Company does not then have securities of any class
registered under Section 12 of the Exchange Act and such Transfer would cause
such registration to be required.

               (5) WCAS shall give written notice to FFT not less than 10
Business Days nor more than 20 Business Days in advance of any distribution by
any Schedule I Purchaser to its limited partners or members if either (a) any
recipient of such distribution is not obligated to sign an Assumption Agreement,
or (b) upon consummation of such distribution this Agreement (other


                                       5
<PAGE>

than the provisions of Section VIII(2), VIII (3), VIII (4) and VIII (5)) will
terminate in accordance with Section IX.

               SECTION III. TAG-ALONG RIGHTS.

               (1) So long as this Agreement remains in effect, with respect to
any proposed Transfer by WCAS or any of its Designated Affiliates (collectively,
the "SELLING STOCKHOLDER") of shares of Company Capital Stock and/or Warrants to
any Person who is not a Permitted Transferee, other than in a Public Offering,
pursuant to a bona fide sale to the public pursuant to Rule 144 under the
Securities Act or pursuant to any agreement or plan of merger or combination,
including any tender or exchange offer in respect thereof, that is approved by
the Board and that provides for equal treatment of all outstanding shares of
Company Capital Stock and Warrants (any such transaction, a "PROPOSED SALE"),
each Schedule I Purchaser (other than WCAS), FFT Purchaser and each of their
Permitted Transferees will have the right to require the proposed Transferee or
acquiring Person to purchase from each such Stockholder and each Permitted
Transferee who exercises its rights under this Section III(1) in accordance with
this Section III(1) (a "TAGGING STOCKHOLDER") a number of shares of Company
Capital Stock and Warrants up to the product (rounded up to the nearest whole
number) of (i) the quotient determined by dividing (A) the aggregate number of
shares of Company Capital Stock and Warrants owned by such Tagging Stockholders
by (B) the aggregate number of shares of Company Capital Stock and Warrants
owned by WCAS and its Designated Affiliates and the Tagging Stockholders and
(ii) the total number of shares of Company Capital Stock and Warrants proposed
to be directly or indirectly Transferred to the transferee or acquiring Person
in the Proposed Sale (a "PROPOSED TRANSFEREE"), at the same price per share of
Company Capital Stock and Warrants and upon the same terms and conditions
(including, without limitation, time of payment, form of consideration and
adjustments to purchase price) as the Selling Stockholder; PROVIDED that in
order to be entitled to exercise its right to sell shares of Company Capital
Stock and Warrants to the Proposed Transferee pursuant to this Section III(1),
each Tagging, Stockholder (x) shall agree to the same covenants with respect to
such Tagging Stockholders, as appropriate, as the Selling Stockholder agrees to
in connection with the Proposed Sale; PROVIDED, HOWEVER, that the aggregate
amount of liability of such Tagging Stockholder with respect to such covenants
shall not exceed the proceeds to such Tagging Stockholder in connection with the
Proposed Sale, and (y) shall make such representations and warranties concerning
its title to the shares of Company Capital Stock and Warrants to be sold in
connection with the Proposed Sale and its authority to enter into and consummate
the Proposed Sale as the Selling Stockholder makes, but shall not be required to
make any other representations and warranties or indemnities other than with
respect to its own representations and warranties.

               (2) Each Tagging Stockholder will be responsible for funding its
proportionate share of any escrow arrangements in connection with the Proposed
Sale and for its proportionate share of any withdrawals therefrom, including
without limitation any such withdrawals that are made with respect to claims
arising out of agreements, covenants, representations, warranties or other
provisions relating the Proposed Sale that were made by the Tagging Stockholder.


                                       6
<PAGE>

               (3) Each Tagging Stockholder will be responsible for its
proportionate share of the reasonable fees, commissions and other out-of-pocket
expenses (collectively, "COSTS") of the Proposed Sale to the extent not paid or
reimbursed by the Company, the Proposed Transferee or another Person (other than
the Selling Stockholder); PROVIDED that the Proposed Sale is consummated and the
liability for such Costs shall not exceed the total purchase price received by
such stockholder for such shares. The Selling Stockholder shall be entitled to
estimate the Tagging Stockholders' proportionate share of such Costs and to
withhold such amounts from payments to be made to the Tagging Stockholder at the
time of closing of such Proposed Sale; PROVIDED that (i) such estimate shall not
preclude the Selling Stockholder from recovering additional amounts from the
Tagging Stockholder in respect of such Tagging Stockholder's proportionate share
of such Costs and (ii) the Selling Stockholder shall reimburse the Tagging
Stockholder to the extent actual amounts are ultimately less than the estimated
amounts or any such amounts are paid by the Company, the Proposed Transferee or
another Person (other than the Selling Stockholder).

               (4) The Selling Stockholder will give notice to the Company of
each Proposed Sale not more than five days after the execution of the definitive
agreement relating to the Proposed Sale, setting forth the number of shares of
Company Capital Stock and Warrants proposed to be so Transferred, the name and
address of the Proposed Transferee, the proposed amount and form of
consideration (and if such consideration consists in part or in whole of
property other than cash, the Selling Stockholder will provide such information,
to the extent reasonably available to the Selling Stockholder, relating to such
non-cash consideration as each of the Tagging Stockholders, may reasonably
request in order to evaluate such non-cash consideration) and other terms and
conditions of payment offered by the Proposed Transferee. If any holders of
Company Capital Stock and Warrants are given an option as to the form and amount
of consideration to be received, all holders of Company Capital Stock and
Warrants shall be given the same option. In the event that any of the terms
and/or conditions set forth in the notice are thereafter amended in any respect,
the Selling Stockholder shall also give written notice of the amended terms and
conditions of the Proposed Sale to the Company, and each Tagging Stockholder
shall be permitted to cancel its exercise of its rights under this Section III
upon delivery of written notice to the Company to such effect and shall be
released from its obligation hereunder. Upon its receipt of any such notice or
amended notice, the Company shall promptly, but in all events within three (3)
Business Days of its receipt thereof, forward copies thereof to each of the
Tagging Stockholders. The Selling Stockholder will deliver or cause to be
delivered to each Tagging Stockholder copies of all transaction documents
relating to the Proposed Sale promptly as the same become available. The
tag-along rights provided by this Section III must be exercised by the Tagging
Stockholders within 10 Business Days following receipt of the notice required by
the preceding sentence by delivery of a written notice to the Selling
Stockholder indicating its desire to exercise its rights and specifying the
number of shares of Company Capital Stock and Warrants it desires to sell (the
"TAG-ALONG NOTICE"). The Tagging Stockholders will be entitled under this
Section III to Transfer to the Proposed


                                       7
<PAGE>

Transferee the number of shares of Company Capital Stock and Warrants calculated
in accordance with Section III(1).

               (5) Any Tagging Stockholder participating in the proposed
disposition shall deliver to the Company, as agent for such Tagging Stockholder,
for transfer to the Proposed Transferee one or more certificates, properly
endorsed for transfer and with all stock transfer taxes paid and stamps affixed,
which represent the number of shares of Company Capital Stock and Warrants that
such Tagging Stockholder elects to dispose of pursuant to paragraph 4 above. The
consummation of such proposed disposition shall be subject to the sole
discretion of the Selling Stockholder, who shall have no liability or obligation
whatsoever to any Tagging Stockholder participating therein other than to obtain
for such Tagging Stockholder the same terms and conditions as those of the
Selling Stockholder. Upon the consummation of any such sale, the Company (i)
shall transfer to the Proposed Transferee a stock certificate or certificates
representing the number of shares of Company Capital Stock and Warrants to be
disposed of by any Tagging Stockholders and (ii) shall promptly thereafter remit
to each Tagging Stockholder (i) that portion of the proceeds of the disposition
to which such Tagging Stockholder is entitled by reason of such participation
and (ii) a stock certificate representing any balance of shares of Company
Capital Stock and Warrants that were not so disposed of (or all shares of
Company Capital Stock and Warrants, in the event the proposed disposition is not
consummated).

               (6) If any Tagging Stockholder exercises its rights under this
Section III, the closing of the purchase of the Company Capital Stock and
Warrants with respect to which such rights have been exercised will take place
concurrently with the closing of the sale of the Selling Stockholder's Company
Capital Stock and Warrants to the Proposed Transferee. If by the end of ninety
(90) days following the date of delivery of the notice of the Proposed Sale
provided by the Company pursuant to Section III(4), the Selling Stockholder and
the Proposed Transferee have not completed the Proposed Sale, each Tagging
Stockholder shall be released from its obligations under this Section III, and
the Tag-Along Notices shall be null and void, and it shall be necessary for the
terms of this Section III to be separately complied with in order to consummate
such Proposed Sale pursuant to this Section III.

               SECTION IV.  DRAG-ALONG RIGHTS.

               (1) So long as this Agreement remains in effect, if WCAS or any
of its Designated Affiliates (collectively, the "DRAGGING STOCKHOLDER") receives
an offer from a Person other than any of their Designated Affiliates (a "THIRD
PARTY") to purchase (in a transaction of a type referred to in the first
sentence of Section III(1)) at least a majority of the shares of Company Capital
Stock then outstanding and such offer is accepted by the Dragging Stockholder,
then each Schedule I Purchaser (other than WCAS), FFT Purchaser and each of
their Permitted Transferees (collectively, the "DRAG-ALONG STOCKHOLDERS") hereby
agrees that, if requested by the Dragging Stockholder, it will Transfer to such
Third Party, subject to the other provisions of this Section IV, on the terms of
the offer so accepted by the Dragging Stockholder, including, without
limitation, time of payment, form and choice of consideration and adjustments to
purchase price,


                                       8
<PAGE>

the number of shares of Company Capital Stock and Warrants equal to the number
of shares of Company Capital Stock and Warrants owned by it multiplied by the
percentage of the then outstanding shares of Company Capital Stock and Warrants
to which the Third Party offer is applicable.

               (2) The Dragging Stockholder will give notice (the "DRAG-ALONG
NOTICE") to the Drag-Along Stockholders of any proposed Transfer giving rise to
the rights of the Dragging Stockholder set forth in Section IV(1) (a "SECTION IV
TRANSFER") within five (5) Business Days following the Dragging Stockholder's
acceptance of the offer referred to in Section IV(1) and, in any event, not less
than 10 Business Days prior to the proposed closing date for such Section IV
Transfer. The Drag-Along Notice will set forth the number of shares of Company
Capital Stock and Warrants proposed to be so Transferred, the name of the
proposed Transferee or acquiring Person, the proposed amount and form of
consideration (and if such consideration consists in part or in whole of
property other than cash, the Dragging Stockholder will provide such
information, to the extent reasonably available to the Dragging Stockholder,
relating to such non-cash consideration as the Drag-Along Stockholders together
may reasonably request in order to evaluate such non-cash consideration), the
number of shares of Company Capital Stock and Warrants sought and the other
terms and conditions of the offer. If any holders of Company Capital Stock
and/or Warrants are given an option as to the form and amount of consideration
to be received, all holders of Company Capital Stock and/or Warrants shall be
given the same option. Each Drag-Along Stockholder (x) shall agree to the same
covenants with respect to such Drag-Along Stockholders, as appropriate, as the
Dragging Stockholder agrees to in connection with the Section IV Transfer;
PROVIDED, HOWEVER, that the aggregate amount of liability of such Drag-Along
Stockholder with respect to such covenants shall not exceed the proceeds to such
Drag-Along Stockholder in connection with the Section IV Transfer and (y) shall
make such representations and warranties concerning its title to the shares of
Company Capital Stock and/or Warrants to be sold in connection with the Section
IV Transfer and its authority to enter into and consummate the Section IV
Transfer as the Dragging Stockholder makes, but shall not be required to make
any other representations and warranties or indemnities other than in respect of
its own representations and warranties. If a Dragging Stockholder does not
request that the Drag-Along Stockholders participate in a Section IV Transfer,
then each Stockholder shall have the right to participate in such proposed
transfer in accordance with its rights under Section III above.

               (3) Each Drag-Along Stockholder will be responsible for funding
its proportionate share of any escrow arrangements in connection with the
Section IV Transfer and for its proportionate share of any withdrawals
therefrom, including without limitation any such withdrawals that are made with
respect to claims arising out of agreements, covenants, representations,
warranties or other provisions relating the Section IV Transfer that were made
by the Drag-Along Stockholder.

               (4) Each Drag-Along Stockholder will be responsible for its
proportionate share of the Costs of the Section IV Transfer to the extent not
paid or reimbursed by the


                                       9
<PAGE>

Company, the Third Party or another Person (other than the Dragging
Stockholder); PROVIDED that such Section IV Transfer is consummated and the
liability for such Costs shall not exceed the total purchase price received by
such Drag-Along Stockholder for such shares and/or Warrants. The Dragging
Stockholder shall be entitled to estimate the Drag-Along Stockholders'
proportionate share of such Costs and to withhold such amounts from payments to
be made to the Drag-Along Stockholder at the time of closing of the Section IV
Transfer; PROVIDED that (i) such estimate shall not preclude the Dragging
Stockholder from recovering additional amounts from the Drag-Along Stockholder
in respect of such Drag-Along Stockholder's proportionate share of such Costs
and (ii) the Dragging Stockholder shall reimburse the Drag-Along Stockholder to
the extent actual amounts are ultimately less than the estimated amounts or any
such amounts are paid by the Company, the Third Party or another Person (other
than the Dragging Stockholder). If the Section IV Transfer is not consummated
within 180 days from the date of the Drag-Along Notice, the Dragging Stockholder
must deliver another Drag-Along Notice in order to exercise its rights under
this Section IV with respect to such Section IV Transfer.

               (5) At the closing of such Section IV Transfer, each of the
Dragging Stockholders shall deliver certificates evidencing the Company Capital
Stock and/or Warrants, as the case may be, then held by it and to be sold in
such sale, duly endorsed for transfer or accompanied by stock powers executed in
blank, against payment of the purchase price therefor by wire transfer to the
account or accounts specified by such Drag-Along Stockholder.

               (6) The proceeds from such Section IV Transfer (and, in the case
of a sale of less than all of the outstanding shares of Company Capital Stock
and Warrants, the number of shares and Warrants to be sold by each Stockholder)
shall be allocated among the Stockholders on a PRO RATA basis, based on the
number of shares of Company Capital Stock and Warrants (treating all "in the
money" options and warrants as the number of shares of Company Common Stock
issuable upon the exercise thereof, less such number of shares of Company Common
Stock and Warrants the aggregate fair market value of which (based on the value
attributed in such sale) would be required to pay the aggregate exercise price
therefor, and treating any shares of convertible preferred stock or debt of the
Company on an "as-converted" basis) then held by each Stockholder.

               SECTION V. CUSTODY AGREEMENT AND POWER OF ATTORNEY. Upon
delivering a Tag Along Notice or receiving a Drag-Along Notice, each Schedule I
Purchaser (other than WCAS), FFT Purchaser and each of their Permitted
Transferees will, if requested by the Selling Stockholder or the Dragging
Stockholder, as the case may be, execute and deliver a custody agreement and
power of attorney in form and substance reasonably satisfactory to the Selling
Stockholder or the Dragging Stockholder, as the case may be, and to such
Schedule I Purchaser, FFT Purchaser or their Permitted Transferees, as the case
may be, with respect to the shares of Company Capital Stock and/or Warrants that
are to be sold by such Stockholders and Permitted Transferees pursuant hereto (a
"CUSTODY AGREEMENT AND POWER OF ATTORNEY"). The Custody Agreement and Power of
Attorney will provide, among other things, that each such Stockholder and
Permitted Transferee will deliver to and deposit in custody with the custodian
and attorney-in-fact named therein a certificate or certificates representing
such shares of Company Capital Stock and Warrants (each duly endorsed in blank
by the registered owner or owners thereof) and irrevocably appoint said
custodian and attorney-in-fact as its agent and attorney-


                                       10
<PAGE>

in-fact with full power and authority to act under the Custody Agreement and
Power of Attorney on its behalf with respect to (and subject to the terms and
conditions of) the matters specified in Section III or Section IV, as the case
may be.

               SECTION VI.  PREEMPTIVE RIGHTS.

               (1) Until the later of (i) the fifth anniversary of the Effective
Date and (ii) the consummation of a Public Offering, the Company hereby grants
to each Stockholder the right to purchase such Stockholder's Proportionate
Percentage (as hereinafter defined) of any future Eligible Offering (as
hereinafter defined). For the purposes of this Section VI, the following terms
shall have the meanings set forth below:

               "PROPORTIONATE PERCENTAGE" means, with respect to any Stockholder
        as of any date, the result (expressed as a percentage) obtained by
        dividing (i) the number of shares of Company Capital Stock owned by such
        Stockholder as of such date by (ii) the total number of shares of
        Company Capital Stock outstanding as of such date.

               "ELIGIBLE OFFERING" means an offer by the Company to sell to any
        person or persons (including any of the Stockholders) for cash, cash
        equivalents, property or indebtedness any equity securities of the
        Company, or any security convertible into or exchangeable for, or
        carrying rights or options to purchase, equity securities of the
        Company, other than an offering by the Company:

                      (i) of shares of Company Common Stock or options to
               purchase shares of Company Common Stock in connection with or
               pursuant to any stock option or stock purchase plan approved by
               the Board to full-time employees, officers, directors,
               consultants and/or advisors to the Company or its subsidiaries;

                      (ii) of securities (x) to the seller(s) of a business in
               connection with an acquisition of such seller's business or (y)
               to a joint venture, in connection with a joint venture project
               (PROVIDED that such seller of joint venture is not an Affiliate
               of the Company;

                      (iii)  pursuant to the Unit Purchase Agreement;

                      (iv) of shares of Company Common Stock in a sale or sales
               to officers and employees in an amount not to exceed, in the
               aggregate, 242,424 shares of Company Common Stock; and

                      (v) in a Public Offering.


                                       11
<PAGE>

               (2) The Company shall, before issuing any securities pursuant to
an Eligible Offering, give written notice thereof to each Stockholder. Such
notice shall specify the security or securities the Company proposes to issue,
the proposed date of issuance, the consideration that the Company intends to
receive therefor and all other material terms and conditions of such proposed
issuance. For a period of 15 days following the date of such notice, each
Stockholder shall be entitled, by written notice to the Company, to elect to
purchase all or any part of such Stockholder's Proportionate Percentage of the
securities being sold in the Eligible Offering; PROVIDED, HOWEVER, that if two
or more securities shall be proposed to be sold as a "unit" in an Eligible
Offering, any such election must relate to such unit of securities. To the
extent that elections pursuant to this Section VI(2) shall not be made with
respect to any securities included in an Eligible Offering within such 15-day
period, then the Company may issue such securities, but only for consideration
not less than, and otherwise on no less favorable terms to the Company than,
those set forth in the Company's notice and only within 60 days after the end of
such 15-day period. In the event that any such offer is accepted by a
Stockholder or Stockholders, the Company shall sell to such Stockholder or
Stockholders, and such Stockholder or Stockholders shall purchase from the
Company, for the consideration and on the terms set forth in the notice as
aforesaid, the securities that such Stockholder or Stockholders shall have
elected to purchase.

               SECTION  VII.  RIGHT OF FIRST OFFER.

               (1) If, after the lapse of restrictions on transfer contained in
Section II, any Schedule I Purchaser or FFT Purchaser or any of their Permitted
Transferees (for purposes of this Section VII, a "SELLER") desires to sell,
exchange or in any other manner dispose of (other than in a manner permitted by
Sections II(1), II(4), III or IV) any shares of Company Capital Stock held by
it, then such Seller shall give to the Company a written notice (a "NOTICE OF
DESIRE TO SELL") which shall set forth in reasonable detail the class and number
of shares of capital stock which it desires to sell (the "SUBJECT SHARES") and
may, if the Seller so chooses to specify, set forth any other terms and
conditions of the desired disposition. The Company shall deliver such Notice of
Desire to Sell to WCAS and FFT promptly upon receipt thereof. A Seller may
deliver a Notice of Desire to Sell whether or not such Seller has received an
offer from a third party to purchase such shares of Company Capital Stock.

               (2) WCAS, FFT and their Designated Affiliates (the "OFFEREES")
shall have the right, exercisable upon written notice to the Seller within 15
days after receipt of any Notice of Desire to Sell (the "OFFER NOTICE"), to
offer to purchase any or all Subject Shares proposed to be sold by the Seller at
a purchase price equal to the proposed purchase price specified in the Notice of
Desire to Sell if so specified, or as proposed in the Offer Notice if not
specified in the Notice of Desire to Sell, and otherwise on the terms and
conditions specified in the Notice of Desire to Sell to the extent so specified
and any additional terms and conditions proposed in the Offer Notice
(collectively, including with respect to purchase price, the "OFFER TERMS").
Each Offer Notice shall state the number of shares to be purchased by the
Offerees delivering such Offer Notice (the "PURCHASING STOCKHOLDERS") and that
the Purchasing Stockholders will purchase such


                                       12
<PAGE>

shares within 45 days thereafter (or such longer period as is necessary to
obtain any necessary consents or approvals or to otherwise comply with
applicable law). In the event that more than one Person exercises its right to
offer to purchase pursuant to this paragraph (2), the allocation among such
Purchasing Stockholders of any shares actually sold pursuant to this paragraph
(2) shall be as agreed by such Purchasing Stockholders; PROVIDED, HOWEVER, if
the number of shares that the Purchasing Stockholders offer to purchase exceeds
the number of Subject Shares and the Purchasing Stockholders do not agree on the
allocation of the Subject Shares prior to the expiration of the 15-day period
specified in this paragraph (2) then the Subject Shares shall be allocated
ratably between Purchasing Stockholders based on the number of shares of Company
Capital Stock owned by such Purchasing Stockholder on the date of such Offer
Notice out of the total outstanding shares of Company Capital Stock on that date
owned by all of the Purchasing Stockholders; PROVIDED FURTHER that any such
Subject Shares allocated to the FFT Purchasers may be allocated among the FFT
Purchasers as such parties may agree.

               (3) If the Offerees deliver, within the period specified in
paragraph (2) above, an Offer Notice with respect to Subject Shares, the Seller
shall sell such Subject Shares to such Purchasing Stockholders on the Offer
Terms within the 45-day period specified in paragraph (2) above (or such longer
period as is necessary to obtain any necessary consents or approvals or to
otherwise comply with applicable law). Following the period specified in
paragraph (2) above, the Seller may (subject to any other applicable
restrictions hereunder) transfer such Subject Shares with respect to which no
Offer Notice was received to any third party; PROVIDED that the Seller may not
sell such shares with respect to which no Offer Notice was received to such
third party on material terms that are the same as or more favorable, in the
aggregate, to such third party than the material terms set forth in the Offer
Terms, in the aggregate. Any such sale with respect to which definitive
documentation is not entered into within 60 days after the expiration of the
period specified in paragraph (2) above, or which is not consummated within 60
days of the execution of such definitive documentation (or such longer period as
is necessary to obtain any necessary consents or approvals or to otherwise
comply with applicable law) shall again be subject to the requirements of this
Section VII.

               SECTION VIII.  FINANCIAL AND OTHER INFORMATION; CONFIDENTIALITY.

               (1) Until the earlier of (i) the date of the first occurrence of
a Public Offering and (ii) the date on which any Stockholder no longer holds at
least 25% of the Company Capital Stock (including for purposes hereof any shares
of Company Common Stock obtained through the conversion of such Stockholders'
shares of Company Class A Common Stock) held by such Stockholder as of the
Effective Date, the Company shall furnish to such Stockholder:

               (a) within 95 days after the end of each fiscal year of the
        Company, a consolidated balance sheet of the Company and its
        subsidiaries as of the end of such fiscal year and the related
        consolidated statements of operations, changes in stockholders' equity
        and consolidated statement of cash flows of the Company and its
        subsidiaries for the fiscal year then ended, together with supporting
        notes thereto, certified without


                                       13
<PAGE>

        qualification as to scope of audit by a firm of independent certified
        public accountants of recognized national standing selected by the
        Board;

               (b) within 50 days after the end of each quarter in each fiscal
        year (other than the last quarter in each fiscal year), a consolidated
        balance sheet of the Company and its subsidiaries and the related
        consolidated statements of operations, changes in stockholders' equity
        and consolidated statement of cash flows of the Company and its
        subsidiaries for the quarter then ended, unaudited but certified by the
        principal financial officer of the Company, such balance sheet to be as
        of the end of such quarter and such statements of operations, changes in

PROVIDED that each such Stockholder shall cause all Confidential Information
relating to the Company to be held in strict confidence in accordance with the
provisions of this Section VIII. After any Stockholder no longer holds 25% of
the Company Capital Stock and or Warrants held by such Stockholder on the date
hereof, but before the first occurrence of a Public Offering, the


                                       14
<PAGE>

Company shall only be obligated pursuant to this Section VIII(1) to furnish to
such Stockholder one annual report per year containing at least the information
described in (a) above.

               (2) Each Stockholder and Permitted Transferee agrees that it will
not use at any time any Confidential Information (as defined below) of which any
such Stockholder or any Permitted Transferee is or becomes aware except in
connection with its investment in the Company.

               (3) Each Stockholder and Permitted Transferee further agrees that
the Confidential Information will be kept strictly confidential and will not be
disclosed by it or its Representatives (as defined below), except (i) as
required by applicable law, regulation or legal process or in response to any
inquiry from a regulatory authority having jurisdiction over such Stockholder,
and only after compliance with Section VIII(4); PROVIDED that this clause (i)
may not be relied upon to the extent any action is taken by a Stockholder or
Permitted Transferee which requires such disclosure and, but for such action,
such disclosure would not have been required) and (ii) that it may disclose the
Confidential Information or portions thereof to those of its officers,
employees, directors and representatives of its legal, accounting and financial
advisors (the persons to whom such disclosure is permissible being
"REPRESENTATIVES") who need to know such information in connection with the
investment by the Stockholder and the Permitted Transferees in the Company;
PROVIDED that such Representatives (x) are informed of the confidential and
proprietary nature of the Confidential Information and (y) agree to be bound by
and perform the provisions of this Section VIII. Each Stockholder agrees to be
responsible for any breach of this Section VIII by its Representatives other
than those Representatives who after the date hereof execute a separate
confidentiality agreement with the Company (it being understood that such
responsibility shall be in addition to and not by way of limitation of any right
or remedy the Company may have against such Representatives with respect to any
such breach).

               (4) If any Stockholder, Permitted Transferee or Representative
becomes legally compelled (including by deposition, interrogatory, request for
documents, subpoena, civil investigative demand or similar process) to disclose
any of the Confidential Information, such Stockholder, Permitted Transferee or
Representative shall provide the Company with prompt and, if legally
permissible, prior written notice of such requirement to disclose such
Confidential Information. Upon receipt of such notice, the Company may seek a
protective order or other appropriate remedy. If such protective order or other
remedy is not obtained, such Stockholder, Permitted Transferee or Representative
agrees to disclose only that portion of the Confidential Information which is
legally required to be disclosed and to take all reasonable steps to preserve
the confidentiality of the Confidential Information; PROVIDED that the
Stockholder is not required to incur any costs in connection therewith. In
addition, such Stockholder, Permitted Transferee and Representative will not
oppose any action (and will, if and to the extent requested by the Company and
is legally permitted to do so, cooperate with and assist the Company, at the
Company's expense and on a reasonable basis, in any reasonable action) by the
Company to obtain an appropriate protective order or other reliable assurance
that confidential treatment will be accorded the Confidential Information.

               (5) "CONFIDENTIAL INFORMATION" means oral and written information
concerning the Company and its subsidiaries furnished to any Stockholder or
Permitted Transferee by or on behalf of the Company (irrespective of the form of
communication and whether such information is so furnished before, on or after
the date hereof), and all analyses, compilations, data, studies, notes,
interpretations, memoranda or other documents prepared by any Stockholder or
Permitted Transferee or any Representative containing or based in whole or in
part on any such furnished information. The term "Confidential Information" does
not include any information which (i) at the time of disclosure or thereafter is
generally available to the public (other than as a result of a disclosure
directly or indirectly by any Stockholder, Permitted Transferee or
Representative in violation hereof), (ii) is or becomes available to any
Stockholder or Permitted Transferee on a nonconfidential basis from a source
other than the Company or its advisors, provided that such source was not known
by the Stockholders or Permitted Transferees to be prohibited from disclosing
such information to it by a legal, contractual or fiduciary obligation owed to
the Company or (iii) is already in the possession of any Stockholder or
Permitted Transferee (other than information furnished by or on behalf of the
Company).

               (6) Until the earlier to occur of (i) the tenth anniversary of
the date of this Agreement and (ii) the date of first occurrence of a Public
Offering, the Company shall allow non-voting observers (the "BOARD OBSERVERS"
and each a "BOARD OBSERVER"), appointed as set forth in this Section VIII(6), to
attend each and every meeting of the Board. During such period, (i) A.S.F.
Co-Investment Partners, L.P. shall have the right to appoint one Board Observer
and (ii) each of California Public Employees' Retirement System, California
Teachers' Retirement System, Chase Equity Partners III, L.P., GS Private Equity
Partners III, L.P., on behalf of itself and the other Affiliates of Goldman,
Sachs & Co., and BT Capital Investors, L.P. shall have the right, on a rotating
annual basis, to appoint the other Board Observers for a one year term.
California Public Employees' Retirement System and California Teachers'
Retirement System shall appoint the first two of such Board Observers to serve
one-year terms. GS Private Equity Partners III, L.P., on behalf of itself and
the other Affiliates of Goldman, Sachs & Co. that are parties hereto, Chase
Capital Partners and BT Capital Investors, L.P. shall appoint the next three of
such Board Observers to serve one-year terms following the expiration of the
previous Board Observers' terms. It is understood that the number of Board
Observers appointed pursuant to clause (ii) above shall alternate between two
and three each year. The appointment and removal of each Board Observer shall be
by written notice from the appropriate Stockholder to the Company and shall take
effect upon the delivery of written notice thereof at the Company's registered
office. Each Board Observer and each Stockholder that has the right to appoint a
Board Observer shall receive copies of all notices, minutes, consents, and other
materials that the Company provides to the members of the Board, PROVIDED,
HOWEVER, that the Company reserves the right to exclude any of the Board
Observers from access to any meeting or any materials if it is reasonably
believed, upon advice of counsel, that such exclusion is necessary to preserve
any privilege or to protect confidential information. Except to the extent so
excluded, the Board Observers may participate in discussions of any and all
matters brought before any meeting it attends as a non-voting observer.

               SECTION IX. DURATION OF AGREEMENT. This Agreement (other than the
provisions of Section VIII(2), VIII(3), VIII(4) and VIII(5)) shall terminate
upon the earlier to occur of (1) the tenth anniversary of the Effective Date and
(2) the consummation of (x) one or more Public Offerings by the Company of
Common Stock having an aggregate offering price to the public of not less than
$100,000,000, or (y) the sale, transfer or other disposition (including a
distribution by a limited partnership to its partners) by the Schedule I
Purchasers to persons or entities not required to become parties hereto of at
least 75% of the shares of Company Common Stock held by the Schedule I
Purchasers on the Effective Date.

               SECTION X.     REGULATORY COMPLIANCE.

               (a)    Regulatory Compliance Cooperation.

                      (i) In the event that a Regulated Holder reasonably
        determines that it has a Regulatory Problem, the Company agrees to take
        all such actions as are reasonably requested by such Regulated Holder in
        order (A) to effectuate and facilitate any transfer by the Regulated
        Holder of any securities of the Company then held by the Regulated
        Holder to any Person designated by the Regulated Holder, (B) to permit
        the Regulated Holder (or any of its Affiliates) to exchange all or any
        portion of the voting Securities then held by such Person on a
        share-for-share basis for shares of a class of non-voting Securities of
        the Company, which non-voting Securities shall be identical in all
        respects to such voting Securities, except that such new Securities
        shall be non-voting and shall be convertible into voting Securities on
        such terms as are requested by the Regulated Holder and reasonably
        acceptable to the Company in light of regulatory considerations then
        prevailing, and (C) to continue and preserve the respective allocation
        of the voting interests with respect to the Company arising out of the
        Regulated Holder's ownership of voting Securities and/or provided for in
        this Agreement before the transfers and amendments referred to above
        (including entering into such additional agreements as are requested by
        the Regulated Holder to permit any Person(s) designated by the Regulated
        Holder to exercise any voting power which is relinquished by the
        Regulated Holder upon any exchange of voting Securities for non-voting
        Securities of the Company). If the Regulated Holder elects to transfer
        Securities of the Company to another Regulated Holder in order to avoid
        a Regulatory Problem, the Company and such other Regulated Holder shall
        enter into such mutually acceptable agreements as such other Regulated
        Holder may reasonably request in order to assist such Regulated Holder
        in complying with applicable laws and regulations to which it is
        subject. Such agreements may include restrictions on the redemption,
        repurchase or retirement of Securities of the Company that would result
        or be reasonably expected to result in such Regulated Holder's holding
        more voting securities or total securities (equity and debt) than it is
        permitted to hold under such laws and regulations.


                                       17
<PAGE>

                      (ii) In the event a Regulated Holder has the right to
        acquire any of the Company's securities from the Company or any other
        Person (as the result of a preemptive offer, pro rata offer or
        otherwise), and a Regulated Holder reasonably determines that it has a
        Regulatory Problem, at the Regulated Holder's request the Company will
        offer to sell to the Regulated Holder non-voting securities (or, if the
        Company is not the proposed seller, will arrange for the exchange of any
        voting securities for non-voting securities immediately prior to or
        simultaneous with such sale) on the same terms as would have existed had
        the Regulated Holder acquired the securities so offered and immediately
        requested their exchange for non-voting securities pursuant to
        subsection (i) above.

                      (iii) In the event that any Affiliate of the Company ever
        offers to issue any of its Securities to the Regulated Holder, then the
        Company will cause such Affiliate to enter into agreements with the
        Regulated Holder substantially similar to this Section X.

               (b)    DEFINITIONS.

                      (i) "Regulated Holder" means any holder of the Company's

        controls such Person) is not entitled to hold, or exercise any material
        right with respect to, all or any portion of the Securities of the
        Company which such Person holds or (ii) when such Person and its
        Affiliates would own, control or have power (including voting rights)
        over a greater quantity of Securities of the Company than is permitted
        under any law or regulation or any requirement of any governmental
        authority applicable to such Person or to which such Person is subject.

           WHEREAS, the Company and each of the Stockholders desire to provide
for certain registration matters relating to their respective holdings of
Company Capital Stock;

           NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements herein contained, the parties hereto hereby agree as
follows:

           1. CERTAIN DEFINITIONS. In addition to the terms defined elsewhere
herein, the following terms shall have the following respective meanings when
used herein with initial capital letters:

           "AFFILIATE" shall have the meaning given to that term in Rule 405
      promulgated under the Securities Act and shall include members of a
      Person's immediate family or trusts for the benefit of members of the
      immediate family of such Person; PROVIDED that officers, directors or
      employees of the Company will not be deemed to be Affiliates of a
      stockholder of the Company for purposes hereof solely by reason of being
      officers, directors or employees of the Company.

           "BOARD" means the Board of Directors of the Company.

           "COMMISSION" shall mean the Securities and Exchange Commission, or
      any other federal agency at the time administering the Securities Act.

           "EXCHANGE ACT" shall mean the Securities Exchange Act of 1934 or any
      similar federal statute, and the rules and regulations of the Commission
      thereunder, all as the same shall be in effect at the time.

           "PUBLIC OFFERING" means the sale of shares of Company Common Stock to
      the public pursuant to an effective registration statement (other than a
      registration statement on Form S-4 or S-8 or any similar or successor
      form) filed under the Securities Act.

           "REGISTRATION EXPENSES" shall mean the expenses so described in
      Section 8 hereof.

           "RESTRICTED STOCK" shall mean any shares of Company Capital Stock,
      the certificates for which are required to bear the legend set forth in
      Section 2 hereof, held by any party to this Agreement.

                                       2
<PAGE>

           "SECURITIES ACT" shall mean the Securities Act of 1933 or any similar
      federal statute, and the rules and regulations of the Commission
      thereunder, all as the same shall be in effect at the time.

           "SELLING EXPENSES" shall mean the expenses so described in Section 8
      hereof.

           2. RESTRICTIVE LEGEND. Each certificate representing shares of
Company Capital Stock, other than shares of Company Capital Stock transferred in
a public sale or as otherwise permitted by Section 3 hereof, shall be stamped or
otherwise imprinted with a legend substantially in the following form:

          "THE SHARES OF [COMMON STOCK][CLASS A COMMON STOCK] EVIDENCED BY THIS
          CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
          AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS THEY
          HAVE BEEN REGISTERED UNDER THAT ACT OR AN EXEMPTION FROM REGISTRATION
          IS AVAILABLE."

           3. NOTICE OF PROPOSED TRANSFER. In addition to any restrictions set
forth in the Stockholders Agreement, dated as of the date hereof among the
Company and the Purchasers, prior to any proposed transfer of any Restricted
Stock (other than under the circumstances described in Sections 4, 5 or 6
hereof), the holder thereof shall give written notice to the Company of its
intention to effect such transfer. Each such notice shall describe the manner of
the proposed transfer and, if reasonably requested by the Company, shall be
accompanied by an opinion of counsel reasonably satisfactory to the Company to
the effect that the proposed transfer of the Restricted Stock may be effected
without registration under the Securities Act, whereupon the holder of such
Restricted Stock shall be entitled to transfer such Restricted Stock in
accordance with the terms of its notice; PROVIDED, HOWEVER, that no such opinion
or other documentation shall be required if such notice shall cover a pro rata
distribution (without payment of additional consideration) by any Purchaser that
is a partnership or limited liability company to its partners or members, as the
case may be. Each certificate for Restricted Stock transferred as above provided
shall bear the legend set forth in Section 2, unless (i) such transfer is in
accordance with the provisions of Rule 144 (or any other rule permitting public
sale without registration under the Securities Act or is pursuant to an
effective registration under the Securities Act) or (ii) the opinion of counsel
referred to above is to the further effect that (or, if no opinion is required,
the Company determines that) the transferee and any subsequent transferee (other
than an affiliate of the Company) would be entitled to transfer such securities
in a public sale without registration under the Securities Act.

               The foregoing restrictions on transferability of Restricted Stock
shall terminate as to any particular shares of Restricted Stock when such shares
shall have been effectively registered under the Securities Act and sold or
otherwise disposed of in accordance with the


                                       3
<PAGE>

intended method of disposition by the seller or sellers thereof set forth in the
registration statement concerning such shares. Whenever a holder of Restricted
Stock is able to demonstrate to the Company (and its counsel) that the
provisions of Rule 144(k) of the Securities Act are available to such holder
without limitation, such holder of Restricted Stock shall be entitled to receive
from the Company, without expense, a new certificate not bearing the restrictive
legend set forth in Section 2.

           4. REQUIRED REGISTRATION.

           (a) At any time after the Effective Date, the holders of a majority
      of the outstanding Restricted Stock then held by the Schedule I Purchasers
      may request the Company to register under the Securities Act all or any
      portion of the Restricted Stock held by such requesting holder or holders
      for sale in the manner specified in such notice; PROVIDED, HOWEVER, that
      the Schedule I Purchasers may not request registration pursuant to this
      Section 4 more than once every six months.

           (b) Promptly following receipt of any notice under this Section 4,
      the Company shall immediately notify any holders of Restricted Stock from
      whom notice has not been received and shall use its best efforts to
      register as soon as possible under the Securities Act, for public sale in
      accordance with the method of disposition specified in such notice from
      the original requesting holders, the number of shares of Restricted Stock
      specified in such notice (and in any notices received from other holders
      of Restricted Stock within 20 days after their receipt of such notice from
      the Company); PROVIDED, HOWEVER, that if the proposed method of
      disposition specified by the original requesting holders shall be an
      underwritten Public Offering, the number of shares of Restricted Stock to
      be included in such an offering may be reduced (PRO RATA among the
      requesting holders of Restricted Stock based on the number of shares of
      Restricted Stock owned by any such holder on the date of such request out
      of the total outstanding shares of Company Capital Stock on that date) if
      and to the extent that the managing underwriter shall be of the opinion
      that such inclusion would adversely affect the marketing of the Restricted
      Stock to be sold. In the event that the proposed method of disposition
      specified by the original requesting holders shall be an underwritten
      Public Offering, the original requesting holders may choose the managing
      underwriter (which shall be a nationally recognized investment banking
      firm), subject to the consent of the Company (which shall not be
      unreasonably withheld). Notwithstanding anything to the contrary contained
      herein, the obligation of the Company under this Section 4 shall be deemed
      satisfied only when a registration statement covering all shares of
      Restricted Stock specified in notices received as aforesaid (subject to
      any cutbacks as contemplated hereinabove), for sale in accordance with the
      method of disposition specified by the requesting holder, shall have
      become effective and, if such method of disposition is a firm commitment
      underwritten Public Offering, all such shares shall have been sold
      pursuant thereto.



                                       4
<PAGE>


           (c) The Company shall be entitled to include in any registration
      statement referred to in this Section 4, for sale in accordance with the
      method of disposition specified by the requesting holders, shares of
      Company Common Stock to be sold by the Company for its own account, except
      as and to the extent that, in the opinion of the managing underwriter (if
      such method of disposition shall be an underwritten Public Offering), such
      inclusion or the inclusion of shares of any other holders would adversely
      affect the marketing of the Restricted Stock to be sold (and in such
      event, such shares to be sold by the Company for its own account or any
      other holders shall be reduced or eliminated before any reduction in the
      number of shares to be sold by requesting holders pursuant to Section
      4(b)). Except as provided in this paragraph (c), the Company will not
      effect any other registration of Company Common Stock, whether for its own
      account or that of other holders, from the date of receipt of a notice
      from requesting holders pursuant to this Section 4 until the completion of
      the period of distribution of the registration contemplated thereby.

           (d) The Company shall not be obligated to file a registration
      statement relating to any registration request under this Section 4:

                 (i) if with respect thereto the managing underwriter, the
           Commission, the Securities Act or the rules and regulations
           thereunder, or the form on which the registration statement is to be
           filed, would require the conduct of an audit other than the regular
           audit conducted by the Company at the end of its fiscal year, in
           which case the filing may be delayed until the completion of such
           audit (and the Company shall, upon request of the parties demanding
           registration pursuant to this Section 4, use its reasonable efforts
           to cause such audit to be completed expeditiously and without
           unreasonable delay); or

                 (ii) if the Company is in possession of material non-public
           information and the Board determines in good faith that disclosure of
           such information would not be in the best interests of the Company
           and its stockholders, in which case the filing of the registration
           statement may be delayed until the earlier of (i) the second business
           day after such conditions shall have ceased to exist and (ii) the
           90th day after receipt by the Company of the written request from the
           holders of a majority of the outstanding Restricted Stock then held
           by the Schedule I Purchasers to register Restricted Stock under this
           Section 4.

           5. PIGGYBACK REGISTRATION. (a) If the Company at any time (other than
pursuant to Section 4 hereof) proposes to register any Company Common Stock
under the Securities Act for sale to the public, whether for its own account or
for the account of other securityholders or both (except with respect to
registration statements on Form S-4 or S-8 or another form not available for
registering the Restricted Stock for sale to the public), it will give written
notice at such time to all holders of outstanding Restricted Stock of its
intention to do so.


                                       5
<PAGE>

Upon the written request of any such holder, given within 20 days after receipt
of any such notice by the Company, to register any of its Restricted Stock
(which request shall state the intended method of disposition thereof), the
Company will use its best efforts to cause the Restricted Stock, as to which
registration shall have been so requested, to be included in the securities to
be covered by the registration statement proposed to be filed by the Company,
all to the extent required to permit the sale or other disposition by the holder
(in accordance with its written request) of such Restricted Stock so registered;
PROVIDED that nothing herein shall prevent the Company from abandoning or
delaying such registration at any time; PROVIDED FURTHER that the only
securities the Company shall be required to register pursuant hereto shall be
shares of Company Common Stock. In the event that any registration pursuant to
this Section 5 shall be, in whole or in part, an underwritten Public Offering of
Company Common Stock, any request by a holder pursuant to this Section 5 to
register Restricted Stock shall specify that either (i) such Restricted Stock is
to be included in the underwriting on the same terms and conditions as the
shares of Company Common Stock otherwise being sold through underwriters under
such registration or (ii) such Restricted Stock is to be sold in the open market
without any underwriting, on terms and conditions comparable to those normally
applicable to offerings of common stock in reasonably similar circumstances. The
number of shares of Restricted Stock to be included in such an underwriting may
be reduced (PRO RATA among the holders of Restricted Stock requesting
registration pursuant to this Section 5 based on the number of shares of
Restricted Stock owned by any such holder on the date of such request out of the
total outstanding shares of Company Capital Stock on that date) if and to the
extent that the managing underwriter shall be of the opinion that such inclusion
would adversely affect the marketing of the securities to be sold by the Company
therein; PROVIDED, HOWEVER, that such number of shares of Restricted Stock shall
not be reduced if any shares are to be included in such underwriting for the
account of any person other than the Company and the holders of Restricted
Stock; PROVIDED FURTHER that the number of shares of Restricted Stock held by
the FFT Purchasers that this Section 5 permits to be included in a registration
may be allocated among the FFT Purchasers as such parties shall agree.

           (b) Notwithstanding anything to the contrary contained in Section 4,
5 or 6 hereof, in the event that there is a firm commitment underwritten Public
Offering of securities of the Company pursuant to a registration covering
Restricted Stock and a holder of Restricted Stock does not elect to sell his
Restricted Stock to the underwriters of the Company's securities in connection
with such offering, such holder shall, to the extent required by such
underwriters with respect to all holders of Restricted Stock, refrain from
selling such Restricted Stock during the period of distribution of the Company's
securities by such underwriters and the period in which the underwriting
syndicate participates in the after market; PROVIDED, HOWEVER, that such holder
shall, in any event, be entitled to sell its Restricted Stock commencing on the
120th day after the effective date of such registration statement.

           6. DEMAND REGISTRATION. (a) At any time after the 180th day following
the initial Public Offering, upon the written request of WCAS or FFT (the
Purchaser or Purchasers making such request, a "DEMAND PARTY") requesting that
the Company effect the registration

                                       6
<PAGE>


under the Securities Act of all or part of such Demand Party's Restricted Stock
and specifying the amount and intended method of disposition thereof, the
Company will promptly give written notice of such requested registration to the
other holders of outstanding Restricted Stock and thereupon will, as
expeditiously as possible, file a registration statement to effect the
registration under the Securities Act of:

           (i) such shares of Restricted Stock which the Company has been so
      requested to register by the Demand Party; and

           (ii) the other shares of Restricted Stock which the Company has been
      requested to register by written request given to the Company within 20
      days after the giving of such written notice by the Company (which request
      shall specify the amount and intended method of disposition of such
      securities);

all to the extent necessary to permit the disposition (in accordance with the
intended method thereof as aforesaid) of the Restricted Stock so to be
registered; PROVIDED that the Company shall not be required to effect the
registration of Restricted Stock at the request of FFT under this Section 6 on
more than one occasion, except as provided in Section 6(d); and PROVIDED,
FURTHER, that the Company shall not be obligated to file a registration
statement relating to any registration request under this Section 6(a):

           (x) within a period of 180 days (or such lesser period as the
      managing underwriters in an underwritten offering may permit) after the
      effective date of any other registration statement relating to any
      registration request under Sections 4, 5 or 6 hereof;

           (y) if with respect thereto the managing underwriter, the Commission,
      the Securities Act or the rules and regulations thereunder, or the form on
      which the registration statement is to be filed, would require the conduct
      of an audit other than the regular audit conducted by the Company at the
      end of its fiscal year, in which case the filing may be delayed until the
      completion of such audit (and the Company shall, upon request of the
      Demand Parties, use its reasonable efforts to cause such audit to be
      completed expeditiously and without unreasonable delay); or

           (z) if the Company is in possession of material non-public
      information and the Board determines in good faith that disclosure of such
      information would not be in the best interests of the Company and its
      stockholders, in which case the filing of the registration statement may
      be delayed until the earlier of (i) the second business day after such
      conditions shall have ceased to exist and (ii) the 90th day after receipt
      by the Company of the written request from a Demand Party to register
      Restricted Stock under this Section 6(a).

Nothing in this Section 6(a) shall operate to limit the right of a Purchaser to
request the registration of Restricted Stock that consists of Company Common
Stock issuable upon

                                       7
<PAGE>

conversion, exercise or exchange of Company Class A Common Stock held by such
Purchaser notwithstanding the fact that at the time of request such Purchaser
holds only Company Class A Common Stock ; PROVIDED that the only securities the
Company shall be required to register pursuant hereto shall be shares of Company
Common Stock. The number of shares of Restricted Stock to be included in such an
underwriting may be reduced (PRO RATA among the holders of Restricted Stock
requesting registration pursuant to this Section 6 based on the number of shares
of Restricted Stock owned by any such holder on the date of such request out of
the total outstanding shares of Company Capital Stock on that date) if and to
the extent that the managing underwriter shall be of the opinion that such
inclusion would adversely affect the marketing of the Restricted Stock to be
sold by the Company therein; PROVIDED, HOWEVER, that such number of shares of
Restricted Stock shall not be reduced if any shares are to be included in such
underwriting for the account of any person other than the Company and the
holders of Restricted Stock; PROVIDED FURTHER that any securities that the
Company proposes to sell for its own account under such registration statement
shall be reduced prior to any reduction of Restricted Stock held by such
Purchaser; PROVIDED FURTHER that the number of shares of Restricted Stock held
by the FFT Purchasers that this Section 6 permits to be included in a
registration may be allocated among the FFT Purchasers as such parties shall
agree. In the event that the number of shares of Restricted Stock requested to
be included in such registration is less than the number which, in the opinion
of the managing underwriter, can be sold, the Company may include in such
registration securities it proposes to sell for its own account up to the number
of securities that, in the opinion of the underwriter, can be sold.

           (b) EFFECTIVE REGISTRATION STATEMENT. A registration requested
pursuant to this Section 6 will not be deemed to have been effected unless it
has become effective; PROVIDED that, if, within 180 days after it has become
effective, the offering of Restricted Stock pursuant to such registration is
interfered with by any stop order, injunction or other order or requirement of
the Commission or other governmental agency or court, then such registration
will be deemed not to have been effected.

           (c) SELECTION OF UNDERWRITERS. If a requested registration pursuant
to this Section 6 involves an underwritten offering and neither the Company nor
any of the Schedule I Purchasers (or Affiliates thereof) are registering any
securities therein, the Demand Parties shall have the right to select the
investment banker or bankers and managers to administer the offering, including
the lead managing underwriter; PROVIDED, HOWEVER, that such investment banker or
bankers and managers shall be reasonably satisfactory to the Company. If a
requested registration pursuant to this Section 6 involves an underwritten
offering and either the Company or any of the Schedule I Purchasers (or their
Affiliates) are registering any securities therein, the Company shall have the
right to select the investment banker or bankers and managers to administer the
offering, including the lead managing underwriter; PROVIDED, HOWEVER, that a
majority in interest of the holders of the Restricted Stock held by all
Purchasers participating in such registration shall have the right to select one
co-manager that is an investment banking firm of nationally recognized standing
to participate in the administration of the offering. Any underwriting agreement
relating to an underwritten public offering shall have representations and

                                       8
<PAGE>

warranties by any Purchaser only to the extent relating to the Purchasers
selling Restricted Stock pursuant to such underwritten offering.

           (d) ADDITIONAL REQUESTS. If as a result of the priority provisions
set forth in Section 6(a), (i) the number of shares of Restricted Stock
registered pursuant to this Section 6 is less than 75% of the number of shares
of Restricted Stock set forth in the first request made by FFT under this
Section 6 and (ii) FFT shall have already requested registration under this
Section 6 on one occasion, then FFT shall have the right to make one or more
additional requests for registration under this Section 6 until such time as at
least 75% of the number of shares of Restricted Stock set forth in such first
request under this Section 6 made by FFT have been registered under this Section
6.

           7. REGISTRATION PROCEDURES. If and whenever the Company is required
by the provisions of Sections 4, 5 or 6 hereof to use its best efforts to effect
the registration of any of the Restricted Stock under the Securities Act, the
Company will, as expeditiously as possible:

           (a) in accordance with the Securities Act and all applicable rules
      and regulations, prepare (and afford counsel for the selling holders
      reasonable opportunity to review and comment thereon) and file with the
      Commission a registration statement (which, in the case of an underwritten
      Public Offering pursuant to Section 4 hereof, shall be on Form S-1, S-3 or
      another form of general applicability satisfactory to the managing
      underwriter selected as therein provided) with respect to such securities
      and use its best efforts to cause such registration statement to become
      and remain effective for the period of the distribution contemplated
      thereby (determined as hereinafter provided);

           (b) prepare (and afford counsel for the selling holders reasonable
      opportunity to review and comment thereon) and file with the Commission
      such amendments and supplements to such registration statement and the
      prospectus used in connection therewith and any documents incorporated by
      reference therein and file such other documents as may be necessary to
      keep such registration statement effective for the period specified in
      paragraph (a) above and to comply with the provisions of the Securities
      Act with respect to the disposition of all Restricted Stock covered by
      such registration statement in accordance with the sellers' intended
      method of disposition set forth in such registration statement for such
      period;

           (c) furnish to each seller and to each underwriter such number of
      copies of the registration statement and the prospectus included therein
      (including each preliminary prospectus), and all amendments, supplements,
      and exhibits thereto, and such other documents as such persons may
      reasonably request in order to facilitate the public sale or other
      disposition of the Restricted Stock covered by such registration statement
      (and the Company hereby consents to the use of any such prospectus,
      together with such supplements and amendments, by the sellers and
      underwriters, if any, in connection with the offer and sale covered
      thereby);

                                       9
<PAGE>


           (d) use its best efforts to register or qualify the Restricted Stock
      covered by such registration statement under the securities or blue sky
      laws of such jurisdictions as the sellers of Restricted Stock or, in the
      case of an underwritten Public Offering, the managing underwriter, shall
      reasonably request (provided that the Company will not be required to (i)
      qualify generally to do business in any jurisdiction where it would not
      otherwise be required to qualify but for this paragraph (d), (ii) subject
      itself to taxation in any such jurisdiction or (iii) consent to general
      service of process in any jurisdiction);

           (e) immediately notify each seller under such registration statement
      and each underwriter, (i) when such registration statement or any
      post-effective amendment or supplement thereto becomes effective or a
      supplement to any prospectus forming a part of such registration statement
      has been filed; (ii) of the issuance by the Commission or any state
      securities authority of any stop order, injunction or other order or
      requirement suspending the effectiveness of such registration statement
      (and the Company shall use best efforts to prevent the initiation of
      proceedings for, prevent the entry of and/or remove such order or
      requirement); (iii) of the happening of any event as a result of which
      such registration statement, as then in effect, the prospectus contained
      therein or any document incorporated by reference therein includes an
      untrue statement of a material fact or omits to state any material fact
      required to be stated therein or necessary to make the statements therein
      not misleading in the light of the circumstances then existing; or (iv) of
      any request by the Commission for the amending or supplementing of such
      registration statement or prospectus or for additional information;

           (f) use its best efforts to furnish, at the request of any seller, on
      the date that Restricted Stock is delivered to the underwriters for sale
      pursuant to such registration, if such securities are being sold through
      underwriters, or on the date that the registration statement becomes
      effective, if such securities are not being sold through underwriters: (i)
      an opinion dated such date of counsel representing the Company for the
      purposes of such registration, addressed to the underwriters, if any, and
      to such seller, stating that such registration statement has become
      effective under the Securities Act and that (A) to the best knowledge of
      such counsel, no stop order suspending the effectiveness thereof has been
      issued and no proceedings for that purpose have been instituted or are
      pending or contemplated under the Securities Act, (B) the registration
      statement, the related prospectus, and each amendment or supplement
      thereof, comply as to form in all material respects with the requirements
      of the Securities Act and the applicable rules and regulations of the
      Commission thereunder (except that such counsel need express no opinion as
      to financial statements, the notes thereto, and the financial schedules
      and other financial and statistical data contained therein) and (C) to
      such other effects as may reasonably be requested by counsel for the
      underwriters or by such seller or its counsel, and (ii) a letter dated
      such date from the independent public accountants retained by the Company,
      addressed to the underwriters, if any, and to such sellers stating that
      they are independent public accountants within the meaning of the
      Securities Act and that, in the opinion of such accountants, the financial
      statements of the Company included in the

                                       10
<PAGE>
     registration statement or the prospectus, or any amendment or supplement
     thereof, comply as to form in all material respects with the applicable
     accounting requirements of the Securities Act, and such letter shall
     additionally cover such other financial matters (including information as
     to the period ending no more than five business days prior to the date of
     such letter) with respect to the registration in respect of which such
     letter is being given as such underwriters or sellers may reasonably
     request;

           (g) take such actions as may be necessary or appropriate to obtain a
      CUSIP number (if none exists) for the Company Common Stock, and make all
      filings and secure all approvals required pursuant to the regulations of
      the National Association of Securities Dealers, Inc. in connection with
      such registration;

           (h) take such actions as may be necessary or appropriate to cause the
      Restricted Stock so to be registered to be listed on the principal
      securities exchange (or on the NASDAQ National Market System, as the case
      may be) on which shares of Company Common Stock are then traded (or, in
      the case of an initial Public Offering, on such national securities
      exchange (or on the NASDAQ National Market System) as the Company shall
      elect);

           (i) use its best efforts to comply with all applicable rules and
      regulations of the Commission, and make available to any holder of
      Restricted Stock, as soon as reasonably practicable (but not more than 15
      months) after the effective date of the registration statement, an
      earnings statement which shall satisfy the provisions of Section 11(a) of
      the Securities Act and the rules and regulations promulgated thereunder;
      and

           (j) make available for inspection by each seller, any underwriter
      participating in any distribution pursuant to such registration statement,
      and any attorney, accountant or other agent retained by such seller or
      underwriter, all financial and other records, pertinent corporate
      documents and properties of the Company, and cause the Company's officers,
      directors and employees to supply all information reasonably requested by
      any such seller, underwriter, attorney, accountant or agent in connection
      with such registration statement and permit such seller, attorney,
      accountant or agent to participate in the preparation of such registration
      statement.

For purposes of paragraphs (a) and (b) above and of Section 4(c) hereof, the
period of distribution of Restricted Stock in a firm commitment underwritten
Public Offering shall be deemed to extend until each underwriter has completed
the distribution of all securities purchased by it, and the period of
distribution of Restricted Stock in any other registration shall be deemed to
extend until the earlier of the sale of all Restricted Stock covered thereby or
six months after the effective date thereof.

           In connection with each registration hereunder, the selling holders
of Restricted Stock will furnish to the Company in writing such information with
respect to themselves and

                                       11
<PAGE>


the proposed distribution by them as shall be reasonably necessary in order to
assure compliance with federal and applicable state securities laws.

           In connection with each registration pursuant to Sections 4, 5 and 6
hereof covering an underwritten Public Offering, the Company agrees to enter
into a written agreement with the managing underwriter selected in the manner
herein provided in such form and containing such provisions as are customary in
the securities business for such an arrangement between major underwriters and
companies of the Company's size and investment stature; PROVIDED, HOWEVER, that
such agreement shall not contain any such provision applicable to the Company
which is inconsistent with the provisions hereof and PROVIDED, FURTHER, HOWEVER,
that the time and place of the closing under said agreement shall be as mutually
agreed upon among the Company, such managing underwriter and the selling holders
of Restricted Stock.

           8. EXPENSES. All expenses incurred by the Company in complying with
Sections 4, 5 or 6 hereof, including, without limitation, all registration,
listing and filing fees, printing expenses, fees and disbursements of counsel
and independent public accountants for the Company (including with respect to
any special audit or "cold comfort" letters), fees of the National Association
of Securities Dealers, Inc., transfer taxes and fees of transfer agents and
registrars, as well as reasonable fees and out-of pocket expenses of not more
than one counsel for all the Schedule I Purchasers and one counsel for all the
FFT Purchasers, but excluding any Selling Expenses, are herein called
"REGISTRATION EXPENSES." All underwriting discounts and selling commissions
applicable to the sale of Restricted Stock are herein called "SELLING EXPENSES."

           The Company will pay all Registration Expenses in connection with
each registration statement filed pursuant to Sections 4, 5 or 6 hereof. All
Selling Expenses in connection with any registration statement filed pursuant to
Sections 4, 5 or 6 hereof shall be borne by the participating sellers in
proportion to the number of shares sold by each, or by such persons other than
the Company (except to the extent the Company shall be a seller) as they may
agree.

           9. INDEMNIFICATION. In the event of a registration of any of the
Restricted Stock under the Securities Act pursuant to Sections 4, 5 or 6 hereof,
the Company will indemnify and hold harmless, to the fullest extent permitted by
law, each seller of such Restricted Stock thereunder, each underwriter of
Restricted Stock thereunder, each of their respective affiliates, each of their
and their affiliates' respective directors, officers, fiduciaries, trustees,
agents, employees, stockholders, general and limited partners and members, and
each other person, if any, who controls such seller or underwriter within the
meaning of the Securities Act, against any losses, claims, damages or
liabilities, joint or several, actions or proceedings (whether commenced or
threatened) in respect thereof (all of the foregoing, collectively, "CLAIMS")
and expenses (including fees and expenses of counsel, and amounts paid in any
settlement effected with the Company's consent, which consent shall not be
unreasonably withheld or delayed) to which such indemnified party may become
subject under the Securities Act or otherwise, insofar


                                       12
<PAGE>

as such Claims or expenses arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in any registration
statement under which such Restricted Stock was registered under the Securities
Act pursuant to Sections 4, 5 or 6, any preliminary prospectus, summary or final
prospectus contained therein, or any amendment or supplement of any thereof, or
any documents incorporated by reference therein, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and will reimburse each such indemnified party for any legal or other expenses
incurred by them in connection with investigating or defending any such Claim;
PROVIDED, HOWEVER, that the Company will not be liable to any such indemnified
party if and to the extent that any such Claim or expense arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission so made in conformity with information pertaining to such
indemnified party furnished by such indemnified party in writing specifically
for use in such registration statement or prospectus.

           In the event of a registration of any of the Restricted Stock under
the Securities Act pursuant to Sections 4, 5 or 6 hereof, each seller of such
Restricted Stock thereunder, severally and not jointly, will indemnify and hold
harmless, to the fullest extent permitted by law, the Company and each person,
if any, who controls the Company within the meaning of the Securities Act, each
officer of the Company who signs the registration statement, each director of
the Company, each underwriter and each person who controls any underwriter
within the meaning of the Securities Act, each other stockholder selling
Restricted Stock under such registration statement and each affiliate, officer,
director, fiduciary, trustee, agent, employee, stockholder, general or limited
partner or member of such selling stockholder against all Claims and expenses
(including fees and expenses of counsel, and amounts paid in any settlement
effected with the indemnifying party's consent, which consent shall not be
unreasonably withheld or delayed) to which the Company or such officer or
director or underwriter or controlling person may become subject under the
Securities Act or otherwise, insofar as such Claims or expenses arise out of or
are based upon any untrue statement or alleged untrue statement of any material
fact contained in the registration statement under which such Restricted Stock
was registered under the Securities Act pursuant to Sections 4, 5 or 6, any
preliminary prospectus, summary or final prospectus contained therein, or any
amendment or supplement of any thereof, or any documents incorporated by
reference therein, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Company and each such indemnified party for any legal or other expenses incurred
by them in connection with investigating or defending any such Claim; PROVIDED,
HOWEVER, that such seller will be liable hereunder to any such indemnified party
if and only to the extent that any such Claim or expense arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in reliance upon and in conformity with information
pertaining to such seller, as such, furnished in writing to the Company by such
seller specifically for use in such registration statement or prospectus;
PROVIDED, FURTHER, HOWEVER, that the liability of each seller


                                       13
<PAGE>


hereunder shall be limited to the proceeds (net of underwriting discounts and
commissions) received by such seller from the sale of Restricted Stock covered
by such registration statement.

           Promptly after receipt by an indemnified party hereunder of notice of
the commencement of any action, such indemnified party shall, if a claim in
respect thereof is to be made against the indemnifying party hereunder, notify
the indemnifying party in writing thereof, but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
such indemnified party under this Section 9 except to the extent such
indemnifying party is materially prejudiced thereby, and in any event will not
relieve such indemnifying party from any liability which it may have to any
indemnified party other than under this Section 9. In case any such action shall
be brought against any indemnified party and it shall notify the indemnifying
party of the commencement thereof, the indemnifying party shall be entitled to
participate in and, to the extent it shall wish, to assume and undertake the
defense thereof with counsel satisfactory to such indemnified party, and, after
notice from the indemnifying party to such indemnified party of its election so
to assume and undertake the defense thereof, the indemnifying party shall not be
liable to such indemnified party under this Section 9 for any legal expenses
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation and of liaison with counsel
so selected; PROVIDED, HOWEVER, that, if the defendants in any such action
include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be reasonable
defenses available to it which are different from or additional to those
available to the indemnifying party, or if the interests of the indemnified
party reasonably may be deemed to conflict with the interests of the
indemnifying party, or if the indemnifying party shall not diligently continue
such defense in good faith, the indemnified party shall have the right to select
a separate counsel and to assume such legal defenses and otherwise to
participate in the defense of such action, with the expenses and fees of such
separate counsel and other expenses related to such participation to be
reimbursed by the indemnifying party as incurred.

           Notwithstanding the foregoing, any indemnified party shall have the
right to retain its own counsel in any such action, but except as set forth
above the fees and disbursements of such counsel shall be at the expense of such
indemnified party unless (i) the indemnifying party shall have failed to retain
counsel for the indemnified person as aforesaid or (ii) the indemnifying party
and such indemnified party shall have mutually agreed to the retention of such
counsel. It is understood that the indemnifying party shall not, in connection
with any action or related actions in the same jurisdiction, be liable for the
fees and disbursements of more than one firm (together with local counsel) to
act as counsel for the indemnified party. The indemnifying party shall not be
liable for any settlement of any proceeding effected without its written consent
(which shall not be unreasonably withheld or delayed), but if settled with such
consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party from and against any loss or
liability by reason of such settlement or judgment. No indemnifying party shall,
without the written consent of the indemnified party (which shall not be
unreasonably withheld or delayed), effect the settlement or compromise of, or
consent to the entry of any judgment with respect to, any pending or threatened
action in respect of which indemnification may be sought hereunder (whether or
not the indemnified party is an actual or


                                       14
<PAGE>

potential party to such action) unless such settlement, compromise or judgment
(i) includes an unconditional release of such indemnified party from all
liability arising out of such action and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of
such indemnified party.

           If for any reason the indemnification provided for in the first two
paragraphs of this Section 9 is unavailable or insufficient to hold harmless an
indemnified party under such paragraphs in respect of any Claims or expenses in
respect thereof referred to therein, then each indemnifying party shall in lieu
of indemnifying such indemnified party contribute to the amount paid or payable
by such indemnified party as a result of such Claims or expenses in such
proportion as appropriate to reflect the relative fault of the Company, on the
one hand, and the underwriters and the sellers of such Restricted Stock, on the
other, in connection with the statements or omissions which resulted in such
Claims or expenses as well as any other relevant equitable considerations,
including the failure to give any notice under the third paragraph of this
Section 9. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact
relates to information supplied by the indemnifying party, on the one hand, or
the indemnified party, on the other, and to the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and each of you agree that it would not be
just and equitable if contributions pursuant to this paragraph were determined
by PRO RATA allocation (even if all of the sellers of such Restricted Stock were
treated as one entity for such purpose) or by any other method of allocation
which did not take account of the equitable considerations referred to above in
this paragraph. The amount paid or payable by an indemnified party as a result
of the Claims and expenses in respect thereof, referred to above in this
paragraph, shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim. Notwithstanding the provisions of this paragraph, no
seller of such Restricted Stock or related indemnified party shall be required
to contribute any amount in excess of the amount of proceeds (net of
underwriting discounts and commissions) received by such seller from the sale of
Restricted Stock covered by such registration statement. No person guilty of
fraudulent misrepresentations (within the meaning of Section 11(f) of the
Securities Act), shall be entitled to contribution from any person who is not
guilty of such fraudulent misrepresentation.

           The indemnification of underwriters provided for in this Section 9
shall be on such other terms and conditions as are at the time customary and
reasonably required by such underwriters. In that event the indemnification of
the sellers of Restricted Stock in such underwriting shall at the sellers'
request be modified to conform to such terms and conditions.

           The indemnification and contribution agreements contained herein
shall be in addition to any other rights to indemnification and contribution
which any indemnified party may have pursuant to law or contract or otherwise,
shall remain operative and in full force and effect regardless of any
investigation made or omitted by or on behalf of any indemnified party and shall
survive the transfer of Restricted Stock by any such party.


                                       15

           10 CHANGES IN COMPANY CAPITAL STOCK. If, and as often as, there are
any changes in Company Capital Stock by way of stock split, stock dividend,
combination or reclassification, or through merger, consolidation,
reorganization or recapitalization, or by any other means, appropriate
adjustment shall be made by the Board in the provisions hereof, as may be
required, so that the rights and privileges granted hereby shall continue with
respect to the Company Capital Stock as so changed.

           11 REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
represents and warrants to each of the Purchasers as follows:

           (a) The execution, delivery and performance of this Agreement by the

      result in a breach of or constitute (with due notice or lapse of time or
      both) a default under any such indenture, agreement or other instrument,
      or result in the creation or imposition of any lien, charge or encumbrance
      of any nature whatsoever upon any of the properties or assets of the

<PAGE>

      rule or regulation of the Commission allowing a holder of Restricted
      Stock to sell any such securities without registration.

           13 MISCELLANEOUS.

           (a) All covenants and agreements contained in this Agreement by or on
      behalf of any of the parties hereto shall bind and inure to the benefit of
      the respective successors and permitted assigns of the parties hereto
      whether so expressed or not. Without limiting the generality of the
      foregoing: (i) any holder of Restricted Stock may assign rights hereunder
      with respect to any of its Restricted Stock to any transferee of such
      Restricted Stock, provided that such transferee agrees in writing to

           (c) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
      WITH THE LAWS OF THE STATE OF NEW YORK.

           (d) This Agreement constitutes the entire agreement of the parties
      with respect to the subject matter hereof and may not be modified or
      amended except by an instrument in writing signed by, and the Company will
      not grant any registration rights, with respect to the equity securities
      of the Company, to any other person without the consent of, the Company
      and (i) the holders of a majority in interest of the Restricted Stock held

           (e) This Agreement shall be of no force or effect unless and until
      the consummation of the Merger (the "EFFECTIVE DATE"); upon such
      consummation, this Agreement shall be in full force and effect.

           (f) This Agreement may be executed in two or more counterparts, each
      of which shall be deemed an original, but all of which together shall
      constitute one and the same instrument.

           (g) Headings and section reference numbers in this Agreement are for
      reference purposes only and shall not in any way affect the meaning or
      interpretation of this Agreement.

           (h) In the event that any one or more of the provisions set forth
      herein shall, for any reason, be held to be invalid, illegal or
      unenforceable in any respect, such invalidity, illegality or
      unenforceability shall not affect any other provision of this Agreement.

           (i) Except as specifically set forth in Section 9 hereof, this
      Agreement is not intended to confer any rights or remedies upon any person
      other than the parties hereto.

           (j) Each party hereto agrees that a remedy at law for any breach or
      threatened breach by such party of this Agreement would be inadequate and
      therefore agrees that any other party hereto shall be entitled to specific
      performance of this Agreement in addition to any other available rights
      and remedies in case of any such breach or threatened breach.

         The  undersigned  acknowledges  receipt of the Prospectus  dated      ,
1999  (the  "Prospectus  "),  of  Concentra  Operating  Corporation,   a  Nevada
corporation  (the  "Issuer"),  and this Letter of  Transmittal  (the  "Letter of
Transmittal"), which together with the Prospectus constitutes the Issuer's offer
(the "Exchange  Offer ") to exchange $1,000  principal  amount of its 13% Senior
Subordinated  Notes due  2009,  Series B (the "New  Notes  "),  for each  $1,000
principal amount of their  outstanding 13% Senior  Subordinated  Notes due 2009,
Series  A (the  "Old  Notes").  Recipients  of the  Prospectus  should  read the
requirements  described  in such  Prospectus  with  respect  to  eligibility  to
participate in the Exchange Offer. Capitalized terms used but not defined herein
have the meaning given to them in the Prospectus.

         The   undersigned   hereby  tenders  the  Old  Notes   described  under
"Description of Old Notes" below pursuant to the terms and conditions  described
in the  Prospectus  and this  Letter  of  Transmittal.  The  undersigned  is the
registered owner of all the Old Notes.

         This Letter of  Transmittal  is to be used by a holder of Old Notes (i)
if certificates  representing  Old Notes are to be forwarded  herewith,  (ii) if
delivery  of Old  Notes is to be made by  book-entry  transfer  to the  Exchange
Agent's  account  at The  Depository  Trust  Company  ("DTC"),  pursuant  to the
procedures  set forth in the section of the  Prospectus  entitled  "The Exchange
Offer," and an Agent's  Message (as defined herein) is not delivered or (iii) if
a tender is made pursuant to the guaranteed  delivery  procedures in the section
of the Prospectus entitled "The Exchange Offer."

         Any  beneficial  owner whose Old Notes are  registered in the name of a
broker,  dealer,  commercial bank, trust company or other nominee and who wishes
to tender  should  contact  such  registered  holder of Old Notes  promptly  and
instruct  such  registered  holder  of Old  Notes to  tender  on  behalf  of the
beneficial  owner. If such beneficial  owner wishes to tender on its own behalf,
such  beneficial  owner must,  prior to completing  and executing this Letter of
Transmittal and delivering its Old Notes,  either make appropriate  arrangements
to register ownership of the Old Notes in such beneficial owner's name or obtain
a properly  completed  bond power from the registered  holder of Old Notes.  The
transfer of record ownership may take considerable time.

         In order to properly  complete this Letter of Transmittal,  a holder of
Old Notes must (i) complete the box entitled "Description of Old Notes," (ii) if
appropriate,  check and  complete  the boxes  relating to  book-entry  transfer,
guaranteed  delivery,   Special  Issuance   Instructions  and  Special  Delivery
Instructions,  (iii)  sign the  Letter  of  Transmittal  by  completing  the box
entitled "Sign Here" and (iv) complete the  Substitute  Form W-9. Each holder of
Old  Notes  should  carefully  read the  detailed  instructions  below  prior to
completing the Letter of Transmittal.

         Holders of Old Notes who desire to tender  their Old Notes for exchange
and (i) whose Old Notes are not immediately available or (ii) who cannot deliver
their Old Notes,  this Letter of Transmittal  and all other  documents  required
hereby to the Exchange Agent on or prior to the Expiration Date, must tender the
Old  Notes  pursuant  to the  guaranteed  delivery  procedures  set forth in the
section of the Prospectus entitled "The Exchange Offer." See Instruction 2.

         Holders  of Old Notes who wish to tender  their Old Notes for  exchange
must complete columns (1) through (3) in the box below entitled  "Description of
Old Notes,"  complete the boxes  entitled and sign the box below  entitled "Sign
Here." If only those columns are  completed,  such holder of Old Notes will have
tendered for exchange all Old Notes listed in column (3) below. If the holder of
Old Notes wishes to tender for exchange less than all of such Old Notes,  column
(4) must be  completed  in full.  In such case,  such holder of Old Notes should
refer to Instruction 5.

Ladies and Gentlemen:

     By executing this Letter of Transmittal and subject to and effective upon
acceptance for exchange of the Old Notes tendered for exchange herewith, the
undersigned will have irrevocably sold, assigned, transferred and exchanged, to
the Issuer, all right, title and interest in, to and under all of the Old Notes
tendered for exchange hereby, and hereby will have appointed the Exchange Agent
as the true and lawful agent and attorney-in-fact (with full knowledge that the
Exchange Agent also acts as agent of the Issuer) of such holder of Old Notes
with respect to such Old Notes, with full power of substitution to (i) deliver
certificates representing such Old Notes, or transfer ownership of such Old

(iii) receive all benefits and otherwise exercise all rights and incidents of
beneficial ownership with respect to such Old Notes, in accordance with the

shall be deemed to be irrevocable and complete with an interest.

     The undersigned hereby represents and warrants that (i) the undersigned is
the owner; (ii) the undersigned has full power and authority to tender,
exchange, assign and transfer the Old Notes and (iii) that when such Old Notes
are accepted for exchange by the Issuer, the Issuer will acquire good and
marketable title thereto, free and clear of all liens, restrictions, charges and

assignment and transfer of the Old Notes tendered for exchange hereby.

     By tendering, the undersigned hereby further represents to the Issuer that

connection with the Exchange Offer will be acquired by the undersigned and such
beneficial owner(s) in the ordinary course of business of the undersigned, (ii)
the undersigned have no arrangement or understanding with any person to
participate in the distribution of the New Notes, (iii) the undersigned and each

connection with any resale of such New Notes; however, by so acknowledging and
by delivering a prospectus, the undersigned will not be deemed to admit that it

accepted for exchange, and to have exchanged, validly tendered Old Notes, if, as
and when the Issuer give oral or written notice thereof to the Exchange Agent.

Date.

     The undersigned acknowledges that the Issuer's acceptance of Old Notes

the section of the Prospectus entitled "The Exchange Offer" and in the
instructions hereto will constitute a binding agreement among the undersigned
and the Issuer upon the terms and subject to the conditions of the Exchange
Offer.

Eligible Institution (unless signed by an Eligible Institution).

     7. TRANSFER TAXES. Except as set forth in this Instruction 7, the Issuer
will pay all transfer taxes, if any, applicable to the exchange of Old Notes
pursuant to the Exchange Offer. If, however, a transfer tax is imposed for any
reason other than the exchange of the Old Notes pursuant to the Exchange Offer,
then the amount of any such transfer taxes (whether imposed on the registered
holder or any other persons) will be payable by the tendering holder. If
satisfactory evidence of payment of such taxes or exemptions therefrom is not
submitted with this Letter of Transmittal, the amount of such transfer taxes
will be billed directly to such tendering holder.

     8. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. If the New Notes are to be
issued, or if any Old Notes not tendered for exchange are to be issued or sent
to someone other than the holder of Old Notes or to an address other than that
shown above, the appropriate boxes on this Letter of Transmittal should be
completed. Holders of Old Notes tendering Old Notes by book-entry transfer may

(including time of receipt), compliance with conditions, acceptance and
withdrawal of tendered Old Notes will be determined by the Issuer in its sole
discretion, which determination will be final and binding. The Issuer reserve
the absolute right to reject any and all Old Notes not properly tendered or any
Old Notes the Issuer's acceptance of which would, in the opinion of counsel for

cured within such time as the Issuer shall determine. Although the Issuer intend
to notify holders of defects or irregularities with respect to tenders of Old
Notes, neither the Issuer, the Exchange Agent nor any other person shall incur
any liability for failure to give such notification. Tenders of Old Notes will
not be deemed to have been made until such defects or irregularities have been
cured or waived. Any Old Notes received by the Exchange Agent that are not
properly tendered and as to which the defects or irregularities have not been
cured or waived will be returned by the Exchange Agent to the tendering holders,
unless otherwise provided in this Letter of Transmittal, as soon as practicable
following the Expiration Date.

     10. WAIVER OF CONDITIONS. The Issuer reserves the right to waive, amend or

                            IMPORTANT TAX INFORMATION

     Under current federal income tax law, a holder of Old Notes whose tendered
Old Notes are accepted for exchange may be subject to backup withholding unless
the holder provides the Issuer (as payor), through the Exchange Agent, with
either (i) such holder's correct taxpayer identification number ("TIN") on
Substitute Form W-9 attached hereto, certifying that the TIN provided on
Substitute Form W-9 is correct (or that such holder of Old Notes is awaiting a
TIN) and that (A) the holder of Old Notes has not been notified by the Internal
Revenue Service that he or she is subject to backup withholding as a result of a
failure to report all interest or dividends or (B) the Internal Revenue Service
has notified the holder of Old Notes that he or she is no longer subject to
backup withholding; or (ii) an adequate basis for exemption from backup
withholding. If such holder of Old Notes is an individual, the TIN is such
holder's social security number. If the Exchange Agent is not provided with the
correct taxpayer identification number, the holder of Old Notes may be subject
to certain penalties imposed by the Internal Revenue Service.

     Certain holders of Old Notes (including, among others, all corporations and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements. Exempt holders of Old Notes should indicate their exempt
status on Substitute Form W-9. A foreign individual may qualify as an exempt
recipient by submitting to the Exchange Agent a properly completed Internal
Revenue Service Form W-8 (which the Exchange Agent will provide upon request)
signed under penalty of perjury, attesting to the holder's exempt status. See
the enclosed Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9 (the "Guidelines") for additional instructions.

     If backup withholding applies, the Issuer is required to withhold 31% of
any payment made to the holder of Old Notes or other payee. Backup withholding
is not an additional federal income tax. Rather, the federal income tax
liability of persons subject to backup withholding will be reduced by the amount
of tax withheld. If withholding results in an overpayment of taxes, a refund may
be obtained from the Internal Revenue Service.

     The holder of Old Notes is required to give the Exchange Agent the TIN
(e.g., social security number or employer identification number) of the record
owner of the Old Notes. If the Old Notes are held in more than one name or are
not held in the name of the actual owner, consult the enclosed Guidelines for
additional guidance regarding which number to report.
