Overview
 
  We are the largest worldwide independent provider of integrated dialysis
services for patients suffering from chronic kidney failure, also known as end
stage renal disease, or ESRD. We provide dialysis and ancillary services to
more than 41,300 patients through a network of 537 outpatient dialysis
facilities, including approximately 3,000 patients and 35 facilities under
management, in 34 states, Washington D.C., Puerto Rico, Guam, Argentina, and
Europe. Of our 537 facilities, 459 facilities servicing more than 37,500
patients are located in the United States. In addition, we provide inpatient
dialysis services at approximately 290 hospitals. We also offer ancillary
services including ESRD laboratory and pharmacy services, physician network
development and management, pre- and post-transplant services, ESRD clinical
research programs, and vascular access management, which is the care of the
entry site to a patient's bloodstream.
 
  On February 27, 1998, we acquired Renal Treatment Centers, Inc., or RTC, then
the fourth largest provider of integrated dialysis services in the United
States, in a stock-for-stock exchange transaction valued at approximately $1.3
billion. The acquisition added 185 facilities servicing approximately 13,200
patients.
 
Business strategy
 
  We seek to further strengthen our position as the leading independent
provider of integrated dialysis services worldwide and to maximize
profitability through the following strategies:
 
  . Expand through strategic acquisitions, de novo developments and
    management agreements
 
  We believe that significant opportunities continue to exist for growing our
patient base through strategic acquisitions, building our own facilities, which
we refer to as de novo developments, and providing management services to
dialysis facilities, both domestically and internationally. Our strategy is to
buy, build, or manage facilities in order to leverage our operations in regions
where we already have a strong market presence or to establish a strong
presence in new markets by acquiring or developing clusters of facilities that
can support new regional operations. We also actively market our ability to
provide management services that assist dialysis facilities in improving both
their financial performance and quality of care. The table below shows our
implementation of this strategy by presenting the number of facilities added
each year through acquisitions, de novo developments and management agreements:

  . Offer an expanded range of ancillary and "Total Renal Care" services
 
  We are committed to broadening the range of ancillary and "Total Renal Care"
services we provide to our ESRD patients. By providing additional ancillary
services, we add value for our patients by improving the quality of their care.
Such services include ESRD laboratory and pharmacy services, vascular access
management, pre- and post-transplant services, nephrology-related clinical
research and pediatric dialysis programs. We believe that by providing
comprehensive ESRD services, we can generate additional revenues with improved
margins, while also providing higher quality service to our patients.
 
  . Achieve Quality/Value/Growth at all of our facilities
 
  Through our Quality/Value/Growth Program, we seek to improve the quality of
care our patients receive while enhancing operating efficiencies and growing
the patient base at our existing facilities. Our Quality Management Team
strives to improve the quality and outcome of dialysis treatments at our
facilities and trains the staff of our regional facility networks. Our Value
Management Team focuses on improving financial and operational measures while
enhancing the quality of care at each center. By providing high-quality,
efficient care, we can grow our patient base at our existing facilities.
 
  . Form strategic alliances with managed care organizations
 
  We believe we are well-positioned to form strategic alliances with managed
care organizations as a result of our ability to:
 
  (1) Cover a wide geographic area in our markets;
 
  (2) Provide comprehensive, integrated "Total Renal Care" ESRD services; and
 
  (3) Deliver high-quality care while reducing overall healthcare costs.
 
  To date, we have established strategic alliances to provide integrated
dialysis and disease management services with leading managed care
organizations including Kaiser Permanente in San Diego and Northern California,
Group Health Cooperative of Puget Sound, Aetna (New Orleans), and Maxicare (New
Orleans).
 
The dialysis industry
 
 End stage renal disease
 
  ESRD is the state of advanced kidney impairment that is irreversible and
requires routine dialysis treatments or kidney transplantation to sustain life.
Dialysis is the removal of waste from the blood of ESRD patients by artificial
means. Patients suffering from ESRD generally require dialysis three times per
week for their entire lives. We estimate that the United States market for
outpatient and inpatient services to ESRD patients exceeded $16 billion in
1998.
 
 Trends
 
  The following are some general trends in the dialysis industry:
 
  . Stable and predictable growth in patient base
 
  According to figures published by the Health Care Financing Administration,
or HCFA, the number of ESRD patients requiring chronic dialysis services in the
United States has increased at an approximate compounded annual growth rate of
8% from approximately 85,000 patients in 1985 to over 250,000 patients in
March 1999.
 
                                       2
<PAGE>
 
  We expect the number of ESRD patients to continue to grow at approximately
the historical rate for the foreseeable future due to:
 
  (1) The aging of the general population;
 
  (2) Better treatment and longer survival of patients with diseases that
      typically lead to ESRD, including diabetes and hypertension; and
 
  (3) Improved medical and dialysis technology.
 
  We believe that the consistent patient growth rate and the necessity of life-
long treatment for most ESRD patients translate into predictable top-line
revenue for us and the other leading dialysis service providers.
 
  . Significant acquisition opportunities and ongoing industry consolidation
 
  The domestic dialysis services industry has been consolidating, with the five
largest dialysis providers increasing their share of dialysis facilities from
approximately 30% in 1992 to 53% in 1997. However, the absolute number of
facilities owned by parties other than the five largest dialysis providers has
not significantly decreased due to the consistent growth in the patient and
facility bases.
 
  We expect consolidation by the largest dialysis providers to continue due to
their ability to leverage corporate and management resources and increase
operating efficiencies. Moreover, the growth of managed care organizations has
led physician owners of private facilities to sell their facilities to the
multi-facility providers, which are better positioned to meet the challenges of
managed care, including the reporting of quality outcomes measures through
clinical information systems and the lowering of overall healthcare costs
through a reduction in hospitalizations.
 
  . Historically stable Medicare reimbursement environment
 
  Since 1972, reimbursement of dialysis services has been covered universally
by the federal government under Medicare regardless of age or income. Under
this system, Medicare reimbursement rates are established by Congress. Medicare
reimbursement rates for dialysis treatments essentially have been flat since
1983 and have declined over 65% in real dollars since 1972. Although this form
of reimbursement limits the allowable charge per treatment, it provides
dialysis providers with predictable and recurring per treatment revenues and
permits providers to retain any profit earned.
 
  We believe that the fixed-rate, government-reimbursed environment of the
dialysis industry favors large providers, like ourselves, able to spread
overhead costs across a broad patient base. In addition, the multi-facility
providers have adapted to fixed reimbursement by improving operating
efficiency, offering ancillary services and accelerating consolidation.
 
  . Attractive international dialysis market
 
  We estimate that there are currently approximately 550,000 to 650,000 ESRD
patients outside the United States. We also believe that the international
patient base has been growing at a compounded annual growth rate of 8 to 9%. In
addition, the international markets are highly fragmented. We estimate that the
major multi-facility providers serviced only approximately 5% of all non-US
dialysis patients in 1998.
 
  Our international expansion strategy targets countries with dialysis markets
similar to that in the United States, characterized by favorable reimbursement
environments and universal coverage of dialysis services. These countries
include Argentina, Germany, Italy, and the United Kingdom, as well as selected
other European and Far Eastern countries. We seek to improve financial
performance at acquired international facilities primarily through the
application of our purchasing and quality-assurance programs and the
streamlining of less efficient operating cost structures.

 Treatment options for ESRD
 
  Treatment options for ESRD include: (a) hemodialysis; (b) peritoneal
dialysis; and (c) kidney transplantation. ESRD patients are treated
predominantly in outpatient treatment facilities. HCFA estimates that, during
1997, 86.4% of the ESRD patients in the United States received hemodialysis
treatment in outpatient facilities, with 12.8% of the remaining patients using
peritoneal dialysis and 0.8% using home hemodialysis. All ESRD patients require
one of the following treatment options to sustain life:
 
  . Hemodialysis
 
  Hemodialysis, the most common form of ESRD treatment, generally is performed
either in a freestanding facility or in a hospital-based facility. Hemodialysis
uses an artificial kidney, called a dialyzer, to remove certain toxins, fluids
and salt from the patient's blood, combined with a machine to control external
blood flow and to monitor certain vital signs of the patient. The dialysis
process occurs across a semi-permeable membrane that divides the dialyzer into
two distinct chambers. While blood is circulated through one chamber, a pre-
mixed dialyzer fluid is circulated through the other chamber. The toxins and
excess fluid from the blood selectively cross the membrane into the dialyzer
fluid, allowing cleansed blood to return into the patient's body. Each
hemodialysis treatment usually lasts approximately three and one-half hours and
usually is performed three times per week.
 
  . Peritoneal dialysis
 
  Peritoneal dialysis generally is performed by the patient at home. There are
several variations of peritoneal dialysis. The most common are continuous
ambulatory peritoneal dialysis, or CAPD, and continuous cycling peritoneal
dialysis, or CCPD. All forms of peritoneal dialysis use the patient's
peritoneal, or abdominal, cavity to eliminate fluid and toxins from the
patient.
 
  CAPD introduces dialysis solution into the patient's peritoneal cavity
through a surgically placed catheter. Toxins in the blood continuously cross
the peritoneal membrane into the dialysis solution. After several hours, the
patient drains the used dialysis solution and replaces it with fresh solution.
This procedure usually is repeated four times per day.
 
  CCPD is performed in a manner similar to CAPD, but uses a mechanical device
to cycle dialysis solution while the patient is sleeping or at rest.
 
  . Transplantation
 
  An alternative treatment that integrated dialysis service companies do not
provide is kidney transplantation. However, we do provide both pre- and post-
transplant nursing services and transplant pharmaceuticals in selected markets
through our pharmacy.
 
  While transplantation, when successful, is generally the most desirable form
of therapeutic intervention, the shortage of suitable donors, side effects of
immunosuppressive drugs given to transplant recipients and dangers associated
with transplant surgery for certain patient populations limit the availability
of this treatment option. Only approximately 5% of all dialysis patients
received a kidney transplant in 1996 and the number of transplants performed
annually has remained relatively stable over the last ten years.

Operations
 
 Location and capacity of facilities
 
  We operate 537 outpatient dialysis facilities. We own, either directly,
through wholly-owned subsidiary corporations or through joint ventures with
non-physicians, 451 of these facilities. Of the remaining facilities, 32 are
partially owned by us with physicians in the United States, and 19 are
partially owned by us with physicians in Italy, and 35 are managed by us. Our
facilities are located as follows:

  We also provide acute inpatient dialysis services to approximately 290
hospitals. Network-wide, we provide training, supplies and on-call support
services to all of our CAPD and CCPD patients.
 
  We believe we have adequate capacity within our existing facilities network
to accommodate greater patient volume. In addition, we currently are expanding
capacity at certain of our facilities by adding additional dialysis stations to
meet growing demand and building de novo facilities where existing facilities
cannot be expanded.
 
 Operation of facilities
 
  Our dialysis facilities are designed specifically for outpatient hemodialysis
and generally contain, in addition to space for dialysis treatments, a nurses'
station, a patient weigh-in area, a supply room, a water treatment space used
to purify the water used in hemodialysis treatments, a dialyzer reprocessing
room (where, with both the patient's and physician's consent, the patient's
dialyzer is sterilized for reuse), staff work areas, offices and a staff lounge
and kitchen. Many of our facilities also have a designated area for training
patients in home dialysis. Each facility also offers amenities for the
patients, for example a color television with headsets at each dialysis
station.
 
  In accordance with conditions for participation in the Medicare ESRD program,
each facility has a qualified medical director. See the subheading "Physician
relationships." Each facility also has an
 
                                       5
<PAGE>
 
administrator, typically a registered nurse, who supervises the day-to-day
operations of the facility and its staff. The staff of each facility typically
consists of registered nurses, licensed practical or vocational nurses, patient
care technicians, a social worker, a registered dietician, a unit clerk and
bio-medical technicians.
 
  All of our facilities offer high-flux and high-efficiency hemodialysis, which
most physicians practicing at our facilities deem suitable for most of their
patients. High-flux and high-efficiency hemodialysis utilize machinery that
allow patients to dialyze in a shorter period of time per treatment because
such methods cleanse the blood at a faster rate than conventional hemodialysis.
Many of our facilities also offer conventional hemodialysis. We consider the
equipment installed in our facilities to be among the most technologically
advanced equipment currently available to the dialysis industry.
 
  Many of our facilities also offer various forms of home dialysis, primarily
CAPD and CCPD. Home dialysis services consist of providing equipment and
supplies, training, patient monitoring and follow-up assistance to patients who
prefer and are able to receive dialysis treatments in their homes. Patients and
their families or other patient assistants are trained by a registered nurse to
perform either CAPD or CCPD at home. Our training programs for home dialysis
generally last two to three weeks. During 1998, approximately 12% of our
patients received peritoneal dialysis.
 
 Inpatient dialysis services
 
  We provide inpatient dialysis services, excluding physician professional
services, to patients in approximately 290 hospitals. We render these services
for a per-treatment fee individually negotiated with each hospital. When a
hospital requests our services, we administer the dialysis treatment at the
patient's bedside or in a dedicated treatment room in the hospital. Examples of
cases in which such inpatient services are required include patients with acute
kidney failure resulting from trauma or similar causes, patients in the early
stages of ESRD and ESRD patients who require hospitalization for other reasons.
 
 Ancillary services--"Total Renal Care"
 
  We provide a comprehensive range of ancillary services to ESRD patients,
including:
 
  . EPO and other pharmaceuticals. The most significant ancillary service
    that we provide is the administration of pharmaceuticals, including
    erythropoietin, or EPO, calcium and iron supplements, upon a physician's
    prescription. EPO is a genetically-engineered form of a naturally
    occurring protein which stimulates the production of red blood cells and
    is used in connection with all forms of dialysis to treat anemia, a
    medical complication frequently experienced by ESRD patients.
 
  . ESRD laboratory services and facilities. We own two licensed clinical
    laboratories, located in Florida and Minnesota, specializing in ESRD
    patient testing. Our laboratories provide both routine laboratory tests,
    some of which are included in the Medicare composite rate for dialysis,
    and non-routine laboratory tests for which an additional fee is charged.
    Our laboratories provide these tests for both our own and other ESRD
    patients throughout the United States. The types of laboratory tests
    performed at the ESRD laboratories consist of: (a) blood tests to monitor
    the ESRD condition, some of the costs of which are reimbursed as part of
    the dialysis composite rate; and (b) blood tests ordered for diseases
    that the patient has in addition to ESRD. In addition, our Minnesota
    laboratory provides certain highly-specialized tests, including
    therapeutic drug monitoring, bone deterioration and renal stone
    monitoring and certain pre- and post-kidney transplant testing. Our
    Florida laboratory has additional capacity available to accommodate our
    expanding patient base. See the subheading "Investigations" under the
    heading "Risk factors."
 
  . Pharmacy. We opened a licensed pharmacy in California in February 1995
    and acquired an additional pharmacy in Texas in May 1998 that provide a
    comprehensive prescription oral drug program to ESRD patients receiving
    treatments at certain of our facilities. The pharmacies also provide
    immuno- suppressive medications that are required to maintain the viabil-
    ity of a transplant patient's new kidney.
 
                                       6
<PAGE>
 
  . Vascular access management. We are the majority owner of an entity that
    provides vascular access management services to ESRD patients. Clotting
    of the hemodialysis vascular access, the entry site to the bloodstream
    for the dialysis procedure, is one of the most common causes of
    hospitalization for ESRD patients. Our vascular access management program
    uses diagnostic and preventive procedures to help keep the access point
    functioning.
 
  . Transplant services. We have a pre- and post-kidney transplant services
    program in which transplant nurses and coordinators train and counsel
    patients and their families while also assisting them in the continuous
    monitoring required for this population.
 
  . ESRD clinical research programs. Our commitment to improve outcomes,
    reduce costs and enhance the quality of life for ESRD patients includes
    participating in research and development of new products and services.
    Total Renal Research, or TRR, which operated for over 17 years as the
    Drug Evaluation Unit, became our subsidiary in 1997. TRR conducts Phase I
    through Phase IV clinical trials on devices, drugs and new technologies
    in the renal and renal-related fields. This clinical research
    organization has conducted over 200 clinical trials, working with over 50
    drug companies and ten device companies, over the last 12 years.
 
  . Pediatric ESRD services. We are committed to bringing our quality
    programs and expertise to a national network of pediatric dialysis
    centers, and we believe we are currently the only non-hospital based
    provider of comprehensive services to pediatric ESRD patients.
 
  . Ancillary testing. Other ancillary services include doppler flow testing
    of the effectiveness of the patient's vascular access for dialysis and
    blood transfusions, electrocardiograms, studies that examine the degree
    of bone deterioration, and nerve conduction studies that examine the
    degree of deterioration of nerves.
 
 Physician relationships
 
  A key factor in the success of a dialysis facility is our relationship with
local nephrologists. As is often true in the dialysis industry, one or a few
physicians account for all or a significant portion of a dialysis facility's
patient referral base. Therefore, our selection of a location for a dialysis
facility is determined in part by the physician or nephrologist selected to
serve as our medical director. An ESRD patient generally seeks treatment at a
facility that is near to his or her home and at which his or her nephrologist
has practice privileges. Consequently, in order to continue to receive
physician referrals of ESRD patients, we rely on our ability to meet the needs
of referring physicians. We currently have relationships with more than 600
nephrologists in our markets.
 
  The conditions of participation in the Medicare ESRD program mandate that
treatment at a dialysis facility be "under the general supervision of a
director who is a physician." We have engaged qualified physicians or groups of
qualified physicians to serve as medical directors for each of our facilities.
Generally, the medical director must be board eligible or board certified in
internal medicine or nephrology and have had at least 12 months of experience
or training in the care of patients at dialysis facilities. At some facilities,
we also contract with one or more physicians to serve as assistant or associate
medical directors or to direct specific programs, such as home dialysis
training.
 
  Medical directors, associate medical directors and assistant medical
directors enter into written contracts with us for a fixed period of time which
specify their duties and establish their compensation. The compensation of the
medical directors and other physicians under contract is separately negotiated
for each facility and generally depends upon competitive factors in the local
market, the physician's professional qualifications, the specific duties and
responsibilities of the physician, and the size and utilization of the facility
or relevant program.
 
  Generally, we have non-competition agreements with our medical directors or
referring physicians. In all cases in which we acquire a facility from one or
more physicians, or where one or more physicians own interests in facilities as
partners, co-shareholders, or members of a limited liability corporation with
us, these
 
                                       7
<PAGE>
 
physicians have agreed to refrain from owning interests in competing facilities
within a defined geographic area for various periods. While infrequent, we have
from time to time experienced competition from a dialysis facility established
by a former medical director following the termination of his or her
relationship with us.
 
Quality
 
  We believe our leading reputation for quality care is a significant
competitive advantage in attracting patients and physicians and in pursuing
growth in the managed care environment. We engage in organized and systematic
efforts to measure, maintain and improve the quality of services we deliver
through the following quality assurance programs:
 
  . Quality Management Program. We have implemented a Quality Management
    Program designed to measure outcomes and improve the quality of our
    services. Our Quality Management Program and Clinical Information System
    have been developed under the direction of our senior vice president,
    quality management and chief medical officer, who is a clinical professor
    of medicine at the University of California Medical Center in
    San Francisco. The Quality Management Program is implemented by our
    corporate director of quality management and over 30 regional quality
    management coordinators. We also have a corporate director of integrated
    quality development who supervises areas that affect the quality of our
    service like education, training and infection control, adding another
    dimension to our integrated approach to quality. In addition, our
    regional biomedical quality management coordinators audit the technical
    and biomedical quality of our facilities. This corporate quality
    management team works with each facility's multi-disciplinary quality
    management team, including the medical director, to implement the
    program. The Quality Management Program involves all areas of our
    services, monitoring and evaluating all of our activities with a focus on
    continuous improvement. We also compile patient hospitalization and
    related patient treatment outcomes data and have developed standards to
    evaluate such data as part of our national Quality Management Program.
 
  . Clinical Information System. To support the Quality Management Program
    and in response to current payor demands for cost-effective healthcare
    treatments with measurable outcomes, we have developed a proprietary PC-
    based, networked Clinical Information System that provides facilities and
    managed care organizations with detailed patient outcome reports and
    critical clinical information. The Clinical Information System has been
    installed in many of our facilities. Furthermore, we have connected
    Kaiser's information system to our Clinical Information System at our
    three Kaiser-dedicated centers in San Diego.
 
  . H.O.M.E.R. We have entered into a strategic alliance with a software
    company to further the development of Health Outcomes Management,
    Evaluation & Research, or H.O.M.E.R., a system that relates treatment
    parameters to patient problems, creating a versatile outcomes database
    for clinical patient encounters. We believe this system will enhance our
    Clinical Information System through its patient-centered, clinical
    management module and will provide operating efficiencies through its
    financial module.
 
  . Physician Advisory Boards. We have several Physician Advisory Boards
    consisting of nephrologists from facilities located in different regions
    of the country who advise management on our various programs. An Academic
    Advisory Board, containing representatives from each university program
    with which we have a relationship, gives senior management access to
    prominent academic leaders and leading nephrologists who provide advice
    on quality and clinical issues. In addition, certain community physicians
    participate on a Physician Advisory Board made up of two components: (a)
    a Guideline Development Committee that provides assistance with clinical
    guideline development, quality management, and other related issues; and
    (b) a Laboratory Advisory Committee that provides feedback on all matters
    concerning our two clinical laboratories. These boards meet periodically
    to discuss quality and related operational issues. We believe our
    reputation for providing quality care is a competitive advantage in
    attracting new patients and new referring physicians.
 
                                       8
<PAGE>
 
  . Patient satisfaction. Since 1991, we have retained an independent
    consulting firm to conduct annual patient satisfaction surveys. These
    surveys track and identify trends in patient satisfaction indicators that
    are in turn shared with management, medical directors and patients for
    discussion. We recently have decided to provide twice-yearly surveys,
    with rapid feedback to the facilities, in order to enhance this vital
    area of our Quality Management Program.
 
Value
 
 Value Management Team
 
  Our Value Management Team is led by a corporate vice president and a group of
corporate directors who assist our local and regional operations managers in
improving facility operations. The team also includes value management
coordinators who work with and train our local and regional managers to analyze
staffing levels, monitor drug and supply utilization and review other
operational measures. The Value Management Team and Quality Management Team
work together to ensure that facilities improve both the quality of services
provided and the efficiency with which those services are provided.
 
Best Demonstrated Practices Program
 
  We have implemented a Best Demonstrated Practices Program as part of our
Quality/Value/Growth Program. This program creates value by benchmarking the
practices of top performing facilities, analyzing their processes and
disseminating this information to all of our facilities to improve the quality
of care while enhancing operating efficiencies. Our Best Demonstrated Practices
Program assesses the performance of each dialysis center in our entire facility
network across a variety of growth, quality, operational, financial and
customer satisfaction measures. Once a facility has demonstrated proficiency
with a certain practice, information and operational systems supporting this
practice are developed and disseminated throughout the organization by our
quality management coordinators, regional operations managers and value
management coordinators. Some of the key areas of focus are quality
measurements, patient satisfaction, staffing levels and supply utilization.
 
Growth
 
  Our disciplined growth strategy focuses on establishing strong regional
networks of facilities through acquisitions, de novo developments and
management agreements. The regional networks allow us to realize efficiencies
in current operations and to leverage our infrastructure as we expand the
number of facilities we operate. We implement our ancillary services and
Quality/Value/Growth Program at all of our new facilities. Our growth strategy
also focuses on adding additional hospital inpatient contracts in order to
increase the number of patients to whom we provide inpatient dialysis services.
Since 1995, we have added 201 facilities through acquisitions, exclusive of the
merger with RTC in which we added 185 facilities, 48 facilities through de novo
developments, and 35 facilities through management contracts.
 
 Acquisitions
 
  Our acquisition strategy is to leverage our operating infrastructure in
existing regions by acquiring centers where we already have a strong market
presence and to establish a strong presence in new markets by acquiring
clusters of facilities that can support new regional operations. In reviewing a
potential acquisition, our evaluation includes analyzing financial pro formas,
reviewing the local competitive market and assessing the target facility's
reputation for providing quality care.
 
  We typically are able to improve an acquired facility's financial performance
and quality of care by:
 
  . Reducing supply and labor costs;
 
  . Eliminating a majority of the general and administrative and private
    company expenses;
 
                                       9
<PAGE>
 
  . Offering additional ancillary services; and
 
  . Implementing our Quality/Value/Growth Program.
 
 De novo developments
 
  We seek continually to identify locations for de novo developments. We
develop new facilities to:
 
  . Further enhance our regional networks;
 
  . Capitalize on referrals by local nephrologists;
 
  . Better serve the managed care market; and
 
  . Accommodate the growing number of ESRD patients.
 
  By developing 51 facilities since 1995, three of which we manage, we believe
that we have gained an expertise in the design, construction and operation of
new dialysis facilities.
 
  The development of a typical outpatient facility generally requires $1.0
million to $1.2 million for initial construction and equipment and $200,000 to
$300,000 for working capital. Based on our experience, a de novo facility
typically takes six to nine months to open from the date of the signing of the
lease, achieves operating profitability by the ninth to eighteenth month of
operation and reaches maturity within three years.
 
 Management agreements
 
  During 1998, we entered into 32 management agreements to assist academic
medical centers, community and county hospitals, non-profit organizations and
privately owned dialysis facilities to improve both their financial performance
and the quality of care they provide. Many of these dialysis facility operators
seek our expertise to help manage their operations more effectively due to:
 
  . The rising costs of providing dialysis services without corresponding
    increases in prices from government payors; and
 
  . Our ability to bring programs like our Quality/Value/Growth Program to
    local facilities, which would be prohibitively expensive for an
    individual operator to develop and implement.
 
  These management agreements are a cost-effective form of expansion for us
because they require little capital and utilize our existing local
infrastructure.
 
 Academic alliances
 
  Academic alliances help us remain on the leading edge of advances in the care
of ESRD patients by fostering relationships with ESRD specialists in the
academic field. We focus on affiliating with leading nephrologic research
institutions to stay abreast of the most current and important ESRD patient
care issues. We support the research efforts of leading academic nephrologists
by providing these institutions selective access to our Clinical Information
System which contains data on much of our large patient base. We have an
Academic Advisory Board which meets semi-annually to review clinical programs
and to discuss ways in which we and our community physicians can work together
on critical research to improve the well being of the growing ESRD patient
population. We are actively pursuing alliances with academic medical centers
and currently work with the following academic institutions to provide the
highest quality care for their ESRD patients:
 
    Children's Memorial Hospital/Northwestern University--Chicago, IL
    Children's National Medical Center--Washington, D.C.
    Erie County Medical Center/SUNY Buffalo--Buffalo, NY
 
                                       10
<PAGE>
 
    Georgetown University--Washington, D.C.
    Harbor/UCLA Medical Center--Los Angeles, CA
    Louisiana State University--New Orleans, LA
    The Regional Kidney Disease Program/Minneapolis Medical Research
    Foundation--Minneapolis, MN
    The Rogosin Institute/Cornell University Medical Center--New York, NY
    The University of California at Los Angeles--Los Angeles, CA
    The University of Minnesota--Minneapolis, MN
    The University of Southern California--Los Angeles, CA
 
Alliances with managed care organizations and physicians
 
 Managed care organizations
 
  We believe we are well-positioned to form strategic alliances with managed
care organizations as a result of our ability to:
 
  . Provide access to a large number of dialysis facilities in a single
    geographic region. Our regional clusters offer managed care payors broad
    facility networks able to support a large portion of each managed care
    payor's ESRD patient population.
 
  . Provide comprehensive, integrated "Total Renal Care" ESRD services. Our
    array of ancillary services allow managed care payors to contract for
    much of their ESRD patients' healthcare needs through a single contract
    with us.
 
  . Deliver high-quality care while reducing overall healthcare
    costs. Through our Quality/Value/Growth Program, managed care payors are
    assured that their patients will receive high-quality care resulting in
    lower costs through a reduction in hospital and other healthcare
    expenses.
 
  The clustering of our facilities has allowed us to offer managed care payors
broad facility networks that can support a large segment of each managed care
payor's ESRD patient populations within each of our markets. As a result of our
managed care programs and the acquisition of RTC, we have approximately 350
contracts with managed care payors including Kaiser Permanente in San Diego and
Northern California, Group Health Cooperative of Puget Sound, Aetna (New
Orleans), and Maxicare (New Orleans).
 
 Physicians/Networks
 
  We seek to organize and manage networks of nephrologists which further
enhance the ability of these nephrologists to provide integrated ESRD services.
We have entered into long-term management contracts with leading nephrologists
who work in partnership with us to provide high-quality, integrated ESRD
services while reducing total costs. These physician networks market the
services of participating nephrologists to preferred provider organizations,
insurance companies, health maintenance organizations and other third-party
payors for ESRD services, both on a discounted fee-for-service basis and on a
prepaid basis. Through a long-term management services agreement, we are
responsible for providing billing, information systems and other services to
the physician networks in return for a management fee.
 
RTC merger
 
  On February 27, 1998, we acquired RTC, then the fourth largest provider of
integrated dialysis services in the United States, in a stock-for-stock
exchange transaction valued at approximately $1.3 billion. The acquisition
added 185 facilities serving approximately 13,200 patients and strengthened our
position as the largest independent dialysis services provider worldwide. The
acquisition provided us with the following benefits:
 
  . Critical mass, stronger regional networks and greater geographic reach;
 
  . Enhanced purchasing and operating efficiencies;
 
                                       11
<PAGE>
 
  . Improved ability to make strategic acquisitions; and
 
  . A platform for international expansion.
 
  RTC's operations added 13 new markets to our existing domestic operations and
increased our penetration in 11 existing markets. Following the acquisition, we
have strong market positions in: California, Colorado, Florida, Georgia,
Kansas, Maryland, Minnesota, North Carolina, Oklahoma, Pennsylvania and Texas.
Integrating acquired operations such as RTC involves significant challenges,
including the sustainability of synergies or cost savings already achieved, and
may lead to unanticipated costs or a diversion of management's attention. See
the heading "Risks inherent in growth strategy" in the section "Risk factors."
 
  After the merger, we announced that we had undertaken a detailed review of
RTC's accounts receivable and other balance sheet accounts in connection with
the completion of the audit of RTC's financial statements for the fiscal year
ended December 31, 1997. As a result of this review, we filed a Form 10-K/A for
RTC's year ended December 31, 1996 and three 10-Q's for each of RTC's quarters
in 1997, which restated RTC's previously audited and unaudited financial
statements. See our Current Report on Form 8-K dated April 30, 1998. Our
analysis of RTC's accounts receivable continued into the first quarter of 1999.
After concluding this analysis, we provided for an additional allowance for
doubtful accounts of $11.5 million related to the acquired RTC accounts
receivable. As a result, the merger benefits are less than we expected.
 
Corporate compliance program
 
  We have implemented a company-wide corporate compliance program as part of
our commitment to comply fully with all applicable laws and regulations and to
maintain high standards of conduct by all of our employees. This program
undergoes continuous review and is enhanced as necessary. A purpose of the
program is to heighten the awareness of our employees and affiliated
professionals of the importance of complying with all applicable laws and
regulations in an increasingly complicated regulatory environment and to ensure
that steps are taken to resolve instances of non-compliance promptly as they
are identified.
 
  The program has been authorized and mandated by our board of directors and
combines existing company policies and practices with new procedures designed
to address areas of particular sensitivity. As part of the program, we adopted
a code of conduct to be followed by each of our employees and affiliated
professionals. All management personnel have reviewed and agreed to abide by
this code of conduct. The program is administered by our chief compliance
officers and a compliance committee consisting of certain of our officers and
senior managers. The compliance committee reports to our board of directors.
 
Sources of revenue reimbursement
 
  The following table provides information for the periods indicated regarding
the percentage of our net operating revenues, including RTC for all periods,
provided by (a) the Medicare ESRD program; (b) Medicaid; (c)
private/alternative payors, such as private insurance and private funds; (d)
hospital inpatient dialysis services; and (e) international operations.

  Medicare reimburses dialysis providers for the treatment of individuals who
are diagnosed with ESRD and are eligible for participation in the Medicare ESRD
program, regardless of age or financial circumstances. For
 
                                       12

each treatment, Medicare pays 80% of the amount set by the Medicare
reimbursement system. In most cases, a secondary payor, usually Medicare
supplemental insurance or the state Medicaid program, pays approximately 20% of
the amount set by the Medicare reimbursement system. All of the states in which
we operate dialysis facilities provide Medicaid benefits to qualified
recipients to supplement their Medicare entitlement.
 
  If a patient does not qualify for Medicaid based on financial need and does
not purchase secondary insurance through a private insurer, the dialysis
provider may not be reimbursed for the 20% portion of the ESRD composite rate
Medicare does not pay. However, a recent Congressional action will allow
dialysis providers to pay their patients' premiums for secondary insurance.
These premiums are generally less than the 20% co-payment that a private
insurer would pay. Dialysis providers would be allowed to capture, as
incremental profit, the difference between the premiums paid to these secondary
insurers and the reimbursement amounts received from them. We plan to pay for a
patient's secondary insurance premium only if the patient does not qualify for
Medicaid and the patient demonstrates an inability to pay for this insurance.
Dialysis providers will be able to pay directly their patients' premiums for
secondary insurance beginning upon the enactment of regulations implementing
the Congressional action, which is expected in the third quarter of 1999.
 
  ESRD patients receiving dialysis become eligible for Medicare coverage at
various times:
 
  . ESRD patients 65 years of age or older who are not covered by an employer
    group health plan are immediately eligible for Medicare coverage.
 
  . ESRD patients 65 years of age or older who are covered by an employer
    group health plan are eligible for Medicare coverage after a 30-month
    coordination period.
 
  . ESRD patients under 65 years of age who are not covered by an employer
    group health plan must wait 90 days after beginning dialysis treatments
    to be eligible for Medicare benefits. During the first 90 days of
    treatment, the patient, Medicaid or a private insurer is responsible for
    payment. In the case of the individual covered by private insurance, this
    responsibility is limited to the terms of the policy, with the patient
    being responsible for the balance.
 
  . ESRD patients under 65 years of age who are covered by an employer group
    health plan must wait 33 months after beginning dialysis treatments
    before Medicare becomes the primary payor. During the first 33 months of
    treatments, the employer group health plan is responsible for payment at
    its negotiated rate or, in the absence of such a rate, at our usual and
    customary rates. The patient is responsible for any deductibles and co-
    payments under the terms of the employer group health plan.
 
  . ESRD patients with an employer group health plan electing home dialysis
    training during the first 90 days of dialysis have Medicare as their
    primary payor after 30 months. If an ESRD patient without an employer
    group health plan begins home dialysis training during the first three
    months of dialysis, Medicare immediately becomes the primary payor.
 
  In August 1993, the Omnibus Budget Reconciliation Act of 1993, or OBRA 93,
became effective. HCFA originally interpreted certain provisions of OBRA 93 to
require employer group health sponsored insurance plans, or private payors, to
be the primary payor for patients who became dually entitled to Medicare
benefits because they developed ESRD after they had earlier been entitled to
Medicare due to age or disability. In July 1994, HCFA instructed the Medicare
fiscal intermediaries to apply the provisions of OBRA 93 retroactively to
August 10, 1993. Accordingly, we billed the responsible private payors as the
primary payors and recognized these revenues, at the generally higher private
rates, as services were rendered for periods after August 10, 1993.
 
  In April 1995, HCFA issued instructions of clarification to the fiscal
intermediaries which stated that it had misinterpreted the OBRA 93 provisions,
and that Medicare would continue as the primary payor despite a patient
obtaining dual eligibility status under the Medicare ESRD provisions.
Accordingly, we began recognizing revenues at Medicare rates for all such
patients going forward from April 1995. We also adjusted our financial
statements to reflect revenues earned at Medicare rates for such patients
during the period from
 
                                       13
<PAGE>
 
August 1993 through April 1995. This resulted in a reduction in revenues for
the period August 1993 through April 1995 of approximately $3.1 million as
these revenues had been previously recognized at the generally higher private
rates.
 
  In June 1995, a federal court issued a preliminary injunction against HCFA
prohibiting HCFA from retroactively applying its reinterpretation of the OBRA
93 provisions to periods prior to its April 1995 instructions of clarification.
After the issuance of this preliminary injunction, we determined that a
permanent injunction would likely be issued, and we adjusted our financial
statements to reflect revenues earned during the period from August 1993
through April 1995 at the generally higher private rates. We made no adjustment
to revenues recognized going forward from April 1995 because the injunction did
not prohibit the prospective effect of HCFA's reinterpretation.
 
  In January 1998, a federal court issued a permanent injunction preventing
HCFA from applying its reinterpretation of the OBRA 93 provisions because that
application would be unlawful retroactive rulemaking. We did not adjust our
revenues in January 1998 in response to the permanent injunction because
revenues had already been recognized at the generally higher private rates
after the issuance of the preliminary injunction in June 1995.
 
 Medicare reimbursement
 
  Under the Medicare reimbursement system, the reimbursement rates are fixed in
advance and have been adjusted from time to time by Congress. Although this
form of reimbursement limits the allowable charge per treatment, it provides us
with predictable and recurring per treatment revenues and permits us to retain
any profit earned.
 
  Medicare has established a composite rate set by HCFA that determines the
Medicare reimbursement available for a designated group of dialysis services,
including the dialysis treatment, supplies used for that treatment, certain
laboratory tests and certain medications. The Medicare composite rate is
subject to regional differences based upon certain factors, including regional
differences in wage earnings. Certain other services and items are eligible for
separate reimbursement under Medicare and are not part of the composite rate,
including certain drugs like EPO, Calcijex and iron supplements, blood for
amounts in excess of three units per patient per year, and certain physician-
ordered tests provided to dialysis patients.
 
  Claims for Medicare reimbursement must generally be presented within 15 to 27
months of treatment depending on the month in which the service was rendered.
Claims for Medicaid secondary reimbursement must be presented within 60 to 90
days after payment of the Medicare claim. We generally submit claims monthly
and are usually paid by Medicare within 15 days of submission.
 
  We receive reimbursement for outpatient dialysis services provided to
Medicare-eligible patients at rates that are currently between $117 and $139
per treatment. This rate is subject to change by legislation. The Medicare ESRD
reimbursement rate did not change from commencement of the program in 1972
until 1983. From 1983 through December 1990 numerous Congressional actions
resulted in a net reduction of the average reimbursement rate from a fixed fee
of $138 per treatment in 1983 to approximately $125 per treatment in 1990.
 
  Congress increased the ESRD reimbursement rate, effective January 1, 1991, by
$1.00 per treatment resulting in the current average ESRD reimbursement rate of
$126 per treatment. In 1990, Congress required that the Department of Health
and Human Services, or HHS, and the Medical Payment Assessment Commission, or
MEDPAC, study dialysis costs and reimbursement procedures and make findings as
to the appropriateness of ESRD reimbursement rates. In March 1999, MEDPAC
recommended a 2.4% to 2.9% increase to the reimbursement rate. However,
Congress has not yet acted on this recommendation, is not required to implement
this recommendation and could either raise or lower the reimbursement rate.
 
 
                                       14
<PAGE>
 
  During the last congressional session, there were various proposals for the
reform of numerous aspects of Medicare. We are unable to predict what, if any,
changes may occur in the Medicare composite reimbursement rate. Any reductions
in the Medicare composite reimbursement rate could have a material adverse
effect on our results of operations, financial condition and business.
 
 Demonstration project
 
  In January 1996, HCFA announced a three-year demonstration project involving
the enrollment of ESRD patients in managed care organizations. The
demonstration project is evaluating the appropriateness of capitation for
dialysis services. The project is adjusting capitation rates based upon
treatment status, age groups, and the cause of renal failure. There were
initially four demonstration project sites selected. Two sites are now actually
implementing the pilot program and we are participating in the project with
both HMOs.
 
  The ESRD demonstration project and the analysis of the results of the project
are expected to continue over the next three to four years. Using the
experience of this project, HCFA will seek to evaluate the feasibility of
allowing managed care plans to participate in the Medicare ESRD program on a
capitated basis. The pilot program, if successful, could result in HCFA
allowing ESRD patients to enroll in managed care organizations. The likelihood
and timing of this decision is impossible to predict.
 
 EPO reimbursement
 
  On June 1, 1989, the FDA approved the production and sale of EPO, and HCFA
approved Medicare reimbursement for EPO's use by dialysis patients. EPO
stimulates the production of red blood cells and is beneficial in the treatment
of anemia, with the effect of reducing or eliminating the need for blood
transfusions for dialysis patients. Physicians began prescribing EPO for their
patients in our dialysis facilities in August 1989. Most of our dialysis
patients receive EPO.
 
   Approximately 23% of our net operating revenues in fiscal 1998 was generated
from the administration of EPO, the majority of which was reimbursed through
the Medicare and Medicaid programs. Therefore, EPO reimbursement significantly
impacts our net income. The Office of the Inspector General of HHS has
recommended that Medicare reimbursement for EPO be reduced from the current
amount of $10 to $9 per 1,000 units. HHS has concurred with this
recommendation; however, HHS has not determined whether it will pursue this
change through the rulemaking process. In addition, President Clinton's
proposed budget for fiscal year 2000 includes a reduction in the Medicare
reimbursement for EPO of the same amount. Congress has yet to act on this
budget proposal. EPO reimbursement programs have been, and in the future may
be, subject to these and other legislative or administrative proposals. We
cannot predict whether future rate or reimbursement method changes will be
made. If such changes are made, they could have a material adverse effect on
our business, results of operations or financial condition. Furthermore, EPO is
produced by a single manufacturer, Amgen Corporation, and any interruption of
supply or product cost increases could adversely affect our operations. For
more information, see the subheading "Dependence on Medicare, Medicaid and
other sources of reimbursement" under the heading "Risk factors."
 
  In April 1996, HCFA notified providers that reimbursement of EPO
administration for a patient with a measurement of red blood cell
concentration, known as a hematocrit measurement, exceeding 36% would be
available only if the 90-day rolling hematocrit measurement for such patient
was 36.5% or less. If the 90-day rolling average hematocrit measure exceeded
36.5%, reimbursement for EPO administration would be denied, except in very
limited instances. In connection with this notification, HCFA instructed its
fiscal intermediaries to review the rolling three month hematocrit averages and
to ascertain compliance therewith. The single fiscal intermediaries for Total
Renal Care, Inc., or TRC, and RTC enacted such instructions in December and
September, 1997, respectively. Subsequently, HCFA notified its fiscal
intermediaries that it was changing the
 
                                       15
<PAGE>
 
foregoing reimbursement policy. Effective for monthly billing periods beginning
on or after March 10, 1998, reimbursement will be available when the 90-day
rolling average hematocrit measure exceeds 36.5%, with payment based on the
lower of the actual dosage billed for the current month or 80% of the prior
month's allowable EPO dosage. In addition, in this notice, HCFA reestablished
the authorization to make payment for EPO for a month when the patient's
hematocrit exceeds 36%, when accompanied by documentation establishing medical
necessity. More specifically, Medicare guidelines now enable dialysis providers
to be: (a) fully reimbursed for increased EPO dosage levels when the patient's
hematocrit exceeds 36% and there is a medical justification for such dosage;
and (b) partially reimbursed for increased EPO dosage levels when the patient's
hematocrit exceeds 36% and there is no such medical justification. This change
has resulted in additional revenues for dialysis providers.
 
 Other drugs and services delivered at centers
 
  At our facilities we provide most of our patients with intravenous drugs,
other ancillary services and testing, representing approximately 8% of our net
operating revenues in 1998. The intravenous drugs we administer include
Calcijex, iron supplements, various antibiotics and other medications. The
ancillary services and testing include studies that examine the degree of bone
deterioration, nerve conduction studies that examine the degree of
deterioration of nerves, doppler flow testing of the effectiveness of patients'
vascular access for dialysis and blood transfusions, and electrocardiograms.
 
  Medicare currently reimburses us separately for the intravenous drugs at a
rate of 95% of the average wholesale price of each drug. The Clinton
administration has proposed a reduction in the reimbursement rate for
outpatient prescription drugs to 83% of the actual wholesale price. We cannot
predict whether Congress will approve this rate change, but if such a change is
implemented, it could have a material adverse effect on our business, results
of operations or financial condition.
 
  With appropriate medical justification, Medicare separately reimburses us for
the provision of ancillary services and testing to ESRD patients in accordance
with a prescribed fee schedule.
 
 Medicaid reimbursement
 
  Medicaid programs are state administered programs partially funded by the
federal government. These programs are intended to provide coverage for
patients whose income and assets fall below state defined levels and who are
otherwise uninsured. The programs also serve as supplemental insurance programs
for the Medicare co-insurance portion and provide certain coverages, like oral
medications, that are not covered by Medicare. State regulations generally
follow Medicare reimbursement levels and coverages without any co-insurance
amounts. Certain states, however, require beneficiaries to pay a monthly share
of the cost based upon levels of income or assets. We are a licensed ESRD
Medicaid provider in the states in which we conduct our business.
 
 Hospital inpatient dialysis services
 
  We provide inpatient dialysis services, excluding physician professional
services, to patients in hospitals pursuant to written agreements with the
hospitals. We provide these services for a per-treatment fee which is
individually negotiated with each hospital. Some of these agreements provide
that we are the exclusive provider of dialysis services to the hospital, but
many of them are non-exclusive. Some of these agreements also allow either
party to terminate the agreement without cause. Competition for the provision
of dialysis services at hospitals with which we have a non-exclusive agreement
and the termination of inpatient dialysis services agreements could have an
adverse effect on us.

Government regulation
 
 General
 
  Our dialysis operations are subject to extensive federal, state and local
governmental regulations. These regulations require us to meet various
standards relating to, among other things:
 
  . Premises;
 
  . Management of facilities;
 
  . Personnel;
 
  . The maintenance of proper records;
 
  . Equipment; and
 
  . Quality assurance programs/patient care.
 
  Our dialysis facilities are subject to periodic inspection by state agencies
and other governmental authorities to determine if we satisfy applicable
standards and requirements. All of our dialysis facilities are certified by
HCFA, as is required for receipt of Medicare reimbursement payments.
 
  Our business would be adversely impacted by:
 
  . Any loss or suspension of (a) federal certifications; (b) authorization
    to participate in the Medicare or Medicaid programs; or (c) licenses
    under the laws of any state or governmental authority in which we
    generate substantial revenues; or
 
  .  Reduction of dialysis reimbursement or reduction of or elimination of
    coverage for dialysis services.
 
  To date, we have not had any difficulty in maintaining our licenses or our
Medicare and Medicaid authorizations. However, our industry will continue to be
subject to government regulation, the scope and effect of which are difficult
to predict. This regulation could adversely impact us in a material way. In
addition, we periodically may be reviewed or challenged by various governmental
authorities which could have an adverse effect on our financial position.
 
 Fraud and abuse under federal law
 
  The "antikickback" statute contained in the Social Security Act imposes
criminal and civil sanctions on persons who receive or make payments in return
for:
 
  . The referral of a patient for treatment; or
 
  . The ordering or purchasing of items or services that are paid for in
    whole or in part by Medicare, Medicaid or similar state programs.
 
  Federal penalties for violation of these laws include imprisonment, fines and
exclusion of the provider from future participation in the Medicare and
Medicaid programs. Civil penalties for violation of these laws include
assessments of $2,000 per improper claim for payment plus twice the amount of
the claim and suspension from future participation in Medicare and Medicaid.
Some state antikickback statutes also include criminal penalties. The federal
statute expressly prohibits traditionally criminal transactions, such as
kickbacks, rebates or bribes for patient referrals. Court decisions have also
said that, under certain circumstances, the statute is also violated when a
purpose of a payment is to induce referrals.
 
  In July 1991 and in November 1992, the Secretary of HHS published regulations
that create exceptions or "safe harbors" for certain business transactions.
Transactions structured within these safe harbors do not violate the
antikickback statute. A business arrangement must satisfy each and every
element of a safe harbor to be protected by that safe harbor. Transactions that
do not satisfy all elements of a relevant safe harbor do not
 
                                       17
<PAGE>
 
necessarily violate the antikickback statute but may be subject to greater
scrutiny by enforcement agencies. We believe our arrangements with referring
physicians are in material compliance with these laws. We seek to structure our
various business arrangements to satisfy as many safe harbor elements as is
practical. Certain of our arrangements with referring physicians do not satisfy
all elements of a relevant safe harbor. Although we have never been challenged
under these statutes and believe we materially comply with these and other
applicable laws and regulations, we could in the future be required to change
our practices or experience a material adverse effect as a result of a
challenge.
 
  The conditions of participation in the Medicare ESRD program require that
treatment at a dialysis facility be "under the general supervision of a
director who is a physician." Generally, the medical director must be board
eligible or board certified in internal medicine or pediatrics and have had at
least 12 months of experience or training in the care of patients at ESRD
facilities. We have by written agreement engaged qualified physicians or groups
of qualified physicians to serve as medical directors for our facilities. At
some facilities we also contract with physicians to serve as assistant or
associate medical directors, or to direct specific programs such as home
dialysis training, or, in a few instances, to provide medical director services
for acute dialysis services provided to hospitals. The compensation of the
medical directors and other physicians under contract is separately negotiated
for each facility and generally depends upon competitive factors in the local
market, the physician's professional qualifications, the specific duties and
responsibilities of the physician and the size and utilization of the facility
or relevant program. Written agreements with the medical directors and other
contracted physicians fix their compensation for periods of one year or more.
 
  Because our medical directors and other contract physicians refer patients to
our facilities, the federal antikickback statute may apply. We believe our
arrangements with these physicians materially comply with the antikickback
statute. Among the available safe harbors is one relevant to our arrangements
with our medical directors and the other physicians under contract. The safe
harbor sets forth six requirements. Certain of our agreements with our medical
directors or other physicians under contract do not satisfy all six of these
requirements. We believe that, except in cases where a facility is in
transition from one medical director to another or where the term of an
agreement with a physician has expired and a new agreement is in negotiation,
our agreements with our medical directors and other contract physicians satisfy
at least five of the six requirements for this safe harbor.
 
  At some of our dialysis facilities, physicians who refer patients to the
dialysis facilities hold interests in partnerships or limited liability
companies owning the facilities. The antikickback statute may apply in these
situations. We believe these business arrangements are in material compliance
with the antikickback statute. While none of these arrangements satisfies all
elements of a relevant small entity investment interests safe harbor, we
believe that each of the partnerships and limited liability companies satisfies
a majority of the safe harbor's elements.
 
  We lease some of our dialysis facilities from entities in which interests are
held by physicians who refer patients to those facilities, and we sublease
space to referring physicians at some of our dialysis facilities. In addition,
a medical facility at which we provide ESRD ancillary services is leased from
physicians who refer patients for the ancillary services. The antikickback
statute may apply in these situations. We believe, however, that these leases
are in material compliance with the antikickback statute and that the leases
satisfy in all material respects each of the elements of the space rental safe
harbor applicable to these arrangements.
 
  On July 21, 1994, the Secretary of HHS proposed a rule that it said "would
modify the original set of safe harbor provisions to give greater clarity to
the rulemaking's original intent." The proposed rule would, among other things,
make changes to the safe harbors discussed in the preceding few paragraphs. We
do not believe that our conclusions with respect to the application of these
safe harbors to our current arrangements would change if the proposed rule were
adopted in the form proposed. It is difficult to predict, however, the outcome
of the rulemaking process or whether changes in the safe harbor rules will
affect us.

 Fraud and abuse under state law
 
  In several states (including California, Florida, Georgia, Kansas,
Louisiana, Maryland, New York, Utah and Virginia) in which we operate dialysis
facilities jointly owned with referring physicians, statutes prohibit
physicians from holding financial interests in various types of medical
facilities to which they refer patients. We believe our joint ownership
relationships with these physicians are within the exceptions stated in these
various state laws, as further described below.
 
  . California. A California statute makes it unlawful for a physician (or an
    immediate family member) who has a financial interest in an entity to
    refer a person to that entity for various services, including laboratory
    services. Under the California statute, "financial interest" includes any
    type of ownership interest, lease, compensation or other form of payment
    (whether in money or otherwise) between a physician and the entity to
    which the physician makes a referral. The statute also prohibits the
    entity to which the referral was made from presenting a claim for payment
    to any payor for a service furnished pursuant to a prohibited referral
    and prohibits a payor from paying for such a service. Violation of the
    prohibition on submitting a claim is a misdemeanor that subjects the
    offender to a fine of up to $15,000 for each violation and possible
    action against licensure.
 
   Some of our facilities perform laboratory services incidental to dialysis
   services pursuant to the orders of referring physicians. Although we do
   not believe that the California statute is intended to apply to laboratory
   services that are provided incident to dialysis services, it is possible
   that the California statute could be interpreted to apply to these
   services. While the California statute includes certain exemptions, it
   includes no explicit exemption for medical director services or other
   services for which we contract with and compensate referring physicians in
   California or for partnership interests of the type held by the referring
   physicians in eight of our facilities in California. Thus, if the
   California statute is interpreted to apply to referring physicians with
   whom we contract for medical director and similar services or to referring
   physicians who hold partnership interests, we would be required to
   restructure some or all of our relationships with these referring
   physicians. We cannot predict the consequences of this type of
   restructuring.
 
  . Florida. A Florida statute prohibits healthcare providers, defined to
    include physicians, from referring a patient for the provision of
    designated health services to an entity in which the healthcare provider
    has an investment interest. The term "designated health services"
    includes clinical laboratory services. Further, a healthcare provider may
    not refer a patient for the provision of any healthcare item or service
    that is not a "designated health service" to an entity in which the
    healthcare provider is an investor unless:
 
       (1) The entity is a corporation with shares publicly traded on a
     national exchange or on the over-the-counter market with total assets
     over $50 million or certain disclosure requirements are met;
 
       (2)  No more than 50% of the value of the investment interests are
     held by investors in a position to make referrals to the entity;
 
       (3)  The terms under which an investment interest is offered to an
     investor who is in a position to make referrals to the entity are no
     different from the terms offered to investors who are not in a
     position to make referrals;
 
       (4)  The terms offered to an investor in a position to make
     referrals are not related to the previous or expected volume of
     referrals from that investor to the entity; and
 
       (5) There is no requirement that an investor make referrals or be in
     a position to make referrals to the entity as a condition for becoming
     or remaining an investor.
 
   The disclosure requirements compel a healthcare provider who makes a
   permitted referral to provide the patient with a written disclosure form
   informing the patient of the existence of the investment interest, the
   names and addresses of at least two alternative sources of such services
   and the name and address of
 
                                      19
<PAGE>
 
   each applicable entity in which the referring provider is an investor. The
   Florida statute carries with it penalties of up to $15,000 for each
   service for any person who presents or causes to be presented a bill or
   claim for services that the person knows or should know is prohibited.
   Furthermore, any healthcare provider or other entity that enters into an
   arrangement or scheme which the physician or entity knows or should know
   has a principal purpose of assuring referrals by the physician to a
   particular entity may be subject to a civil penalty of up to $100,000 for
   each arrangement. A violation of the disclosure requirements constitutes a
   misdemeanor and may be grounds for disciplinary action. We believe that we
   and our referring physicians are exempt from the Florida statute.
 
  . Georgia. A Georgia statute prohibits a healthcare provider, defined to
    include physicians, from referring a patient for the provision of
    designated health services to an entity in which the healthcare provider
    has an investment interest, unless the provider satisfies certain
    disclosure requirements. An "investment interest" is defined as an equity
    or debt security issued by an entity, including units or other interests
    in a partnership, but excludes certain investments in publicly-held
    corporations. A "designated health service" is defined to include
    clinical laboratory services, pharmaceutical services and outpatient
    surgical services. To comply with the Georgia statute, the healthcare
    provider must furnish the patient with a written disclosure form approved
    by the provider's board of licensure, informing the patient of:
 
       (1) The existence of the investment interest;
 
       (2) The name and address of each entity in which the referring
     provider is an investor; and
 
       (3) The patient's right to obtain the items or services at the
     location or from the healthcare provider or supplier of the patient's
     choice.
 
   In addition, the provider must post a copy of the disclosure form in a
   conspicuous public place in the provider's office. Neither a healthcare
   provider nor any entity may present a claim for payment to any
   individual, third-party payor or other entity for services provided
   pursuant to a prohibited referral. If the healthcare provider or entity
   improperly collects any amount, the provider or entity must refund the
   amount to the payor. Any provider or other entity that enters into an
   arrangement or scheme which the provider or entity knows or should know
   has a principal purpose of assuring referrals by the provider to a
   particular entity is subject to a civil penalty of up to $50,000 for each
   arrangement or scheme. Furthermore, any person who presents or causes to
   be presented a bill for a claim for services that the person knows or
   should know is for a service for which payment may not be made under the
   Georgia statute is subject to a civil penalty of up to $15,000 for each
   service. We believe that all physicians with an investment interest who
   also refer patients to our dialysis facilities are in compliance with the
   disclosure requirements of the Georgia statute and are thus exempt from
   this statute.
 
  . Kansas. A Kansas statute provides that a licensee's license may be
    revoked, suspended or limited in the event the licensee has committed an
    act of unprofessional conduct. Under the Kansas statute, unprofessional
    conduct includes referring a patient to a healthcare entity for services
    if the licensee, defined to include a physician, has a significant
    investment interest in the healthcare entity, unless the licensee informs
    the patient in writing of the investment interest and the ability of the
    patient to obtain services elsewhere. The Kansas statute defines
    "healthcare entity" to mean any corporation, firm, partnership or other
    business entity which provides services for diagnosis or treatment of
    human health conditions and which is owned separately from a referring
    licensee's principal practice. The Kansas statute also defines
    "significant investment interest" to mean ownership of at least 10% of
    the shares of stock of the corporation which owns or leases the
    healthcare entity. We believe that physicians with a "significant
    investment interest" who also refer patients to our dialysis facilities
    are in compliance with the disclosure requirements of the Kansas statute.
 
  . Louisiana. A Louisiana statute prohibits healthcare providers, defined to
    include physicians, from making referrals outside the same group practice
    as that of the referring healthcare provider to any other healthcare
    provider, licensed healthcare facility or provider of healthcare goods
    and services, including
 
                                       20
<PAGE>
 
   providers of clinical laboratory services, when the referring provider has
   a financial interest served by such referral. An exclusion from the
   prohibition will apply if, in advance of any referral, the referring
   provider discloses to the patient, in writing, the existence of such
   financial interest. The Louisiana statute defines "financial interest" to
   mean a significant ownership or investment interest established through
   debt, equity or other means and held by a healthcare provider or a member
   of a provider's immediate family, as well as any form of direct or
   indirect compensation for referral. Any referring healthcare provider with
   a financial interest who does not comply with the Louisiana statute
   disclosure requirement must refund all sums the provider received in
   payment for the goods and services furnished or rendered without
   disclosure of the financial interest. We believe that all physicians who
   have a "financial interest" and who also refer patients to our dialysis
   facilities are in compliance with the Louisiana statute.
 
  . Maryland. A Maryland statute prohibits healthcare practitioners from
    referring patients to a healthcare entity in which the practitioner or
    the practitioner's immediate family owns a beneficial interest or has a
    compensation arrangement. The term "compensation arrangement" does not
    include an arrangement between a healthcare entity and a healthcare
    practitioner, or immediate family member of a practitioner, as an
    independent contractor, if the arrangement is for identifiable services,
    the amount of the compensation under the arrangement is consistent with
    the fair market value of the service and is not determined in a manner
    that takes into account the volume or value of any referrals by the
    practitioner and the compensation is provided in accordance with an
    agreement that would be commercially reasonable even if no referrals were
    made. We believe that we will be exempt from the Maryland statute.
 
  . New York. Several New York statutes relate to self-referrals. A
    practitioner, defined to include physicians, authorized to order clinical
    laboratory services or certain other referred services generally may not
    make a referral for such services to an authorized healthcare provider
    where such practitioner or an immediate family member has a financial
    relationship with the healthcare provider receiving the referral. The New
    York statutes provide that a healthcare provider or a referring
    practitioner may not present or cause to be presented to any individual
    or third-party payor or other entity a claim or other demand for payment
    for clinical laboratory services that is prohibited. Under the New York
    statutes, a "financial relationship" is defined to mean an ownership
    interest, investment interest or compensation arrangement.
 
   Generally, the New York statutes exempt from the New York referral
   prohibition a practitioner's referral to a healthcare provider in which
   the practitioner or an immediate family member has a financial interest
   for clinical laboratory services if:
 
       (1) It is related to practitioner services personally provided by
     the referring practitioner or provided by a practitioner in the same
     group as the referring practitioner;
 
       (2) It is related to in-office ancillary services;
 
       (3) It is related to a health maintenance organization or other type
     of managed care program;
 
       (4) It is related to inpatient hospital services;
 
       (5) It is related to referrals by a hospital of patients for
     clinical laboratory services to be provided by the hospital;
 
       (6) The financial relationship with the hospital does not relate
     directly to the services for which the referral was made; or
 
       (7) It is determined not to pose a substantial risk of payor or
     patient abuse.
 
   The New York statutes also make an exception to the New York referral
   prohibition in the event of an ownership interest or investment interest
   of the practitioner or immediate family member in a healthcare provider,
   upon proper disclosure being made, if (a) the services provided and the
   practitioner or the
 
                                       21
<PAGE>
 
   patient are located in a rural area; or (b) the ownership interest or
   investment interest is based on the ownership in a general hospital
   itself, and not merely a subdivision thereof.
 
   In addition to providing the exceptions discussed above, the New York
   statutes exclude certain types of relationships from the New York referral
   prohibition. The New York statutes provide that an ownership interest or
   an investment interest generally does not exist based solely on the
   ownership of investment securities of a publicly-traded company with total
   assets of over $100 million. Further, the New York statutes generally
   exclude the following from their definition of "compensation arrangement":
 
       (1) Payments for the rental or lease of space;
 
       (2) Administrative services arrangements between a general hospital
     and a practitioner or immediate family member;
 
       (3) Medical director or medical advisory board services arrangements
     between a healthcare provider, other than a general hospital, and a
     practitioner;
 
       (4) Recruitment arrangements;
 
       (5) Isolated financial transactions;
 
       (6) Compensation arrangements between a group practice and salaried
     practitioner of the group practice; and
 
       (7) Other arrangements that are determined not to pose a substantial
     risk of payor or patient abuse.
 
   A practitioner must disclose to the patient, in the case of referrals not
   subject to the New York referral prohibition, the financial relationship
   prior to making the referral if the financial relationship is either
   (a) an ownership or investment interest in the healthcare provider to
   which the referral is being made; or (b) a compensation arrangement with
   such healthcare provider that is in excess of fair market value or that is
   based upon the volume and value of the providers' services.
 
   Because dialysis itself is not a clinical laboratory service or other
   service covered by the New York referral prohibition, we believe that only
   the New York disclosure requirement should need to be satisfied for those
   joint ownership relationships we maintain with referring physicians. We
   believe that, to the extent only the New York disclosure requirement is
   applicable, all physicians who have a financial interest and who also
   refer patients to the dialysis facilities with which we have consultant
   contracts are in compliance with the New York statutes. The facilities in
   New York with which we have consultant contracts may, however, perform
   laboratory services incidental to dialysis services pursuant to the orders
   of the referring physicians. Although we do not believe that the New York
   referral prohibition is intended to apply to laboratory services provided
   incident to dialysis services, it is possible that the New York referral
   prohibition could be interpreted to apply to these services. There is no
   explicit exception to the New York referral prohibition for medical
   director services or other services for which we contract with and
   compensate referring physicians in New York. Thus, if the New York
   Statutes are interpreted to apply to referring physicians with whom we
   contract, we could be required to restructure these relationships. It is
   difficult to predict the consequences of this restructuring.
 
  . Utah. A Utah statute prohibits physicians from referring patients,
    clients, or customers to any clinical laboratory, ambulatory or surgical
    care facilities, or other treatment or rehabilitation services
    facilities, in which the physician or a member of the physician's
    immediate family has any financial relationship, unless the physician at
    the time of making the referral discloses that relationship, in writing,
    to the patient, client, or customer and such written disclosure states
    that the patient may choose any facility or service center for purposes
    of having the laboratory work or treatment service performed. The Utah
    statute defines "financial relationship" to generally mean any ownership
    or investment interest in an entity or any compensation arrangement with
    an entity. We believe that all physicians who have a "financial
    relationship" and who also refer patients to our dialysis facilities are
    in compliance with the Utah statute.
 
 
                                      22
<PAGE>
 
  . Virginia. A Virginia statute generally prohibits a physician from
    referring a patient for health services to an entity outside the
    physician's office if the physician or any of the physician's immediate
    family members is an investor in that entity unless (a) the physician
    directly provides health services within the entity and will be
    personally involved with the provision of care to the referred patient or
    (b) has been granted an exception by the Virginia Board of Health
    Professions, or the VBHP. Violation of the Virginia statute by the
    physician subjects the entity to a monetary penalty of up to $20,000 per
    referral or claim if the entity knows or has reason to know that the
    referral is prohibited by the Virginia statute. Investment interests
    acquired prior to February 1, 1993, including the minority interests
    which physicians hold in our Virginia facilities, were required to be in
    compliance with the Virginia statute by July 1, 1996.
 
   We believe that physicians who refer patients to dialysis facilities
   directly provide healthcare within such facilities and are "personally
   involved with the provision of care" to such referred patients within the
   meaning of the Virginia statute. We also believe that, as a public policy
   matter, it would be reasonable to argue that the VBHP should grant an
   exception to a physician who is an investor in a dialysis facility to
   which the physician refers his or her patients for care. We are unaware,
   however, of any official interpretation of the Virginia statute or the
   grant of any exception by the VBHP indicating acceptance of these views.
   We believe that the ownership of our Virginia facilities could be
   restructured to conform to the requirements of the Virginia statute if
   necessary due to future official interpretations differing from our
   interpretations.
 
 Stark I / Stark II
 
  The Omnibus Budget Reconciliation Act of 1989 includes certain provisions,
known as Stark I, that restrict physician referrals for clinical laboratory
services to entities with which a physician or an immediate family member has a
"financial relationship." Stark I may be interpreted by HCFA to apply to our
operations. Regulations interpreting Stark I, however, have created an
exception to its applicability regarding services furnished in a dialysis
facility if payment for those services is included in the ESRD composite rate.
We believe that our compensation arrangements with Medical Directors and other
physicians under contract are in material compliance with Stark I.
 
  OBRA 93 contains certain provisions, known as Stark II, that restrict
physician referrals for certain "designated health services" to entities with
which a physician or immediate family member has a "financial relationship."
The entity is prohibited under Stark II, as is the case for entities restricted
by Stark I from claiming payment for such services under the Medicare or
Medicaid programs, is liable for the refund of amounts received pursuant to
prohibited claims, is subject to civil penalties of up to $15,000 per service
and can be excluded from future participation in the Medicare and Medicaid
programs. Comparable provisions applicable to clinical laboratory services
became effective in 1992. Stark II provisions which may be relevant to us
became effective on January 1, 1995.
 
  A "financial relationship" under Stark II is defined as the physician's
ownership or investment interest in, or a compensation arrangement with, the
entity. We have entered into compensation agreements with our medical directors
and other referring physicians. Some of our medical directors own equity
interests in entities which operate our dialysis facilities. Some of our
dialysis facilities are leased from entities in which referring physicians hold
interests, and we sublease space to referring physicians at some of our
dialysis facilities. In addition, some of the medical directors and other
physicians from whom we have acquired dialysis facilities own our common stock
or options to acquire our common stock. We believe that the ownership of the
stock and stock options and the other ownership interests and lease
arrangements for such facilities are in material compliance with Stark II.
Proposed Stark II regulations could require us to restructure the stock and
stock option ownership.
 
                                       23
<PAGE>
 
  Stark II includes certain exceptions. A personal services compensation
arrangement is excepted from Stark II prohibitions if:
 
  . The arrangement is set out in writing, signed by the parties, and
    specifies the services covered by the arrangement;
 
  . The arrangement covers all of the services to be provided by the
    physician, or immediate family member of the physician, to the entity;
 
  . The aggregate services contracted for do not exceed those that are
    reasonable and necessary for the legitimate business purposes of the
    arrangement;
 
  . The term of the arrangement is for at least one year;
 
  . The compensation to be paid over the term of the arrangement is set in
    advance, does not exceed fair market value and is not determined in a
    manner that takes into account the volume or value of any referrals or
    other business generated between the parties;
 
  . The services to be performed do not involve a business arrangement or
    other activity that violates any state or federal law; and
 
  . The arrangement meets other requirements that may be imposed pursuant to
    regulations promulgated by HCFA.
 
  We believe that our compensation arrangements with medical directors and
other contract physicians materially satisfy these exceptions to the Stark II
prohibitions.
 
  Payments made by a lessor to a lessee for the use of premises are excepted
from Stark II prohibitions if:
 
  . The lease is set out in writing, signed by the parties, and specifies the
    premises covered by the lease;
 
  . The space rented or leased does not exceed that which is reasonable and
    necessary for the legitimate business purposes of the lease or rental and
    is used exclusively by the lessee when being used by the lessee, subject
    to certain permitted common areas payments;
 
  . The lease provides for a term of rental or lease of at least one year;
 
  . The rental charges over the term of the lease are set in advance, are
    consistent with fair market value and are not determined in a manner that
    takes into account the volume or value of any referrals or other business
    generated between the parties;
 
  . The lease would be commercially reasonable even if no referrals were made
    between the parties; and
 
  . The lease meets other requirements that may be imposed pursuant to
    regulations promulgated by HCFA.
 
  We believe that our leases with referring physicians materially satisfy these
exceptions to the Stark II prohibitions.
 
  The Stark II exception provisions applicable to physician ownership interests
in entities to which they make referrals do not encompass the kinds of
ownership arrangements that referring physicians hold in certain of our
subsidiaries that operate dialysis facilities.
 
  For purposes of Stark II, "designated health services" include clinical
laboratory services, equipment and supplies, home health services, outpatient
prescription drugs and inpatient and outpatient hospital services. We believe
that the language and legislative history of Stark II and related regulations
indicate that Congress did not intend to include dialysis services and the
services and items provided incident to dialysis services. Our provision of, or
arrangement and assumption of financial responsibility for, outpatient
prescription drugs, including EPO and IDPN, clinical laboratory services,
facility dialysis services and supplies, home dialysis supplies and equipment
and services to hospital inpatients and outpatients under our dialysis services
 
                                       24
<PAGE>
 
agreements with hospitals, include services and items which could, however, be
construed as designated health services within the meaning of Stark II.
Although we do not bill Medicare or Medicaid for hospital inpatient and
outpatient services, our Medical Directors may request or establish a plan of
care that includes dialysis services for hospital inpatients and outpatients
that may be considered a referral within the meaning of Stark II.
 
  HCFA may interpret Stark II to apply to our operations. Consequently, Stark
II may require us to restructure existing compensation agreements with our
medical directors and to repurchase or to request the sale of ownership
interests in subsidiaries and partnerships held by referring physicians or, in
the alternative, to refuse to accept referrals for designated health services
from these physicians. We believe, but cannot assure, that if Stark II is
interpreted to apply to our operations, we will be able to bring our financial
relationships with referring physicians into material compliance with Stark II.
We would be materially impacted if HCFA interprets Stark II to apply to us and
we could not achieve that compliance. A broad interpretation of Stark II to
include items provided incident to dialysis services would apply to our
competitors, as well.
 
 Medicare
 
  Because the Medicare program represents a substantial portion of the federal
budget, Congress takes action in almost every legislative session to modify the
Medicare program for the purpose of, or with the result of, reducing the
amounts payable from the program to healthcare providers. Legislation or
regulations may be enacted in the future that may significantly modify the ESRD
program or substantially reduce the amount paid for our services. Further,
Statutes or regulations may be adopted which impose additional requirements for
eligibility to participate in the federal and state payment programs. Any
legislation or regulations of this type could adversely affect our business
operations in a material way.
 
 International regulation
 
  Our operations are subject to extensive government regulation by virtually
every country in which we operate. Although such regulations differ from
country to country, in general, non-U.S. regulations are designed to accomplish
the same objectives as U.S. regulations regarding the operation of dialysis
centers: the provision of quality healthcare for patients, the maintenance of
occupational, health, safety and environmental standards and the provision of
accurate reporting and billing for government payments and/or reimbursement. In
addition, each country has its own payment and reimbursement rules and
procedures, and some countries prohibit ownership of healthcare providers by
foreign interests or establish other regulatory barriers to direct ownership by
foreign companies. In those countries, we work within the framework of local
laws to establish alternative contractual arrangements for the management of
facilities.
 
  Given the difficulties inherent with any operator entering a market for the
first time, there can be no assurance that we will be able to replicate our
successful history of completing, and integrating, domestic acquisitions. Any
failure to integrate efficiently foreign acquisitions or to realize expected
synergies and cost savings could have a material adverse effect on our
business, results of operations and financial condition.
 
 Florida laboratory payment dispute
 
  Our Florida-based laboratory subsidiary is the subject of a third-party
carrier review relating to certain claims submitted by us for Medicare
reimbursement. We understand that similar reviews have been undertaken with
respect to other providers' laboratory activities in Florida and elsewhere. The
carrier has alleged that 99.3% of the tests performed by this laboratory for
the review period it initially identified, from January 1995 to April 1996,
were not properly supported by the prescribing physicians' medical
justification. The carrier subsequently requested billing records with respect
to the additional period from May 1996 to March 1998. The carrier has issued a
formal overpayment determination in the amount of $5.6 million and has
suspended all payments of claims related to this laboratory. The carrier has
withheld approximately $11 million to date. In addition the carrier has
informed the local offices of the Department of Justice, or DOJ, and HHS of
this matter.
 
                                       25
<PAGE>
 
  We have consulted with outside counsel, reviewed our records, are disputing
the overpayment determination vigorously and have provided extensive supporting
documentation of our claims. We have cooperated with the carrier to resolve
this matter and have initiated the process of a formal review of the carrier's
determination. The first step in this formal review process is a hearing before
a hearing officer at the carrier, which is scheduled for June 1999. We have
received minimal responses from the carrier to our repeated requests for
clarification and information regarding the continuing payment suspension. In
February 1999, our Florida-based laboratory subsidiary filed a complaint
against the carrier and HHS seeking a court order to lift the payment
suspension. We initiated this action only after serious consideration and the
unanimous approval of our board of directors, and we believe it is necessary to
bring a prompt resolution to this payment dispute. We are unable to determine
at this time:
 
  . When this matter will be resolved or when the laboratory's payment
    suspension will be lifted;
 
  . What, if any, of the laboratory claims will be disallowed;
 
  . What action the carrier, DOJ or HHS may take with respect to this matter;
 
  . What the outcome of the carrier's review of the periods from May 1996
    through March 1998 will be and whether it will include the initiation of
    another payment suspension;
 
  . Whether additional periods may be reviewed by the carrier; or
 
  . Any other outcome of this investigation or our lawsuit.
 
  Any determination adverse to us could have an adverse impact on our business,
results of operations or financial condition.
 
 The Health Insurance Portability and Accountability Act of 1996
 
  The Health Insurance Portability and Accountability Act of 1996, or HIPAA,
among other things, allows individuals who lose or change jobs to transfer
their insurance, limits exclusions for preexisting conditions, and establishes
a pilot program for medical savings accounts. In addition, HIPAA also expands
federal attempts to combat healthcare fraud and abuse by making amendments to
the Social Security Act and the federal criminal code. Among other things,
HIPAA creates a new "Health Care Fraud and Abuse Control Account," under which
"advisory opinions" are issued by the Office of the Inspector General, or OIG,
regarding the application of the antikickback statute, certain criminal
penalties for Medicare and Medicaid fraud are extended to other federal
healthcare programs, the exclusion authority of the OIG is expanded, Medicare
and Medicaid civil monetary penalty provisions are extended to other federal
healthcare programs, the amounts of civil monetary penalties are increased, and
a criminal health care fraud statute is established.
 
 The False Claims Act
 
  The federal False Claims Act, or FCA, is another means of policing false
bills or requests for payment in the healthcare delivery system. In part, the
FCA imposes a civil penalty on any person who:
 
  . Knowingly presents, or causes to be presented, to the federal government
    a false or fraudulent claim for payment or approval;
 
  . Knowingly makes, uses, or causes to be made or used, a false record or
    statement to get a false or fraudulent claim paid or approved by the
    federal government;
 
  . Conspires to defraud the federal government by getting a false or
    fraudulent claim allowed or paid; or
 
  . Knowingly makes, uses or causes to be made or used, a false record or
    statement to conceal, avoid, or decrease an obligation to pay or transmit
    money or property to the federal government.
 
  The penalty for a violation of the FCA ranges from $5,000 to $10,000 for each
fraudulent claim plus three times the amount of damages caused by each such
claim. The FCA has been used widely by the federal
 
                                       26
<PAGE>
 
government to prosecute Medicare fraud in areas such as coding errors, billing
for services not rendered, the submission of false cost reports, billing
services at a higher reimbursement rate than is appropriate, billing services
under a comprehensive code as well as under one or more component codes, and
billing for care which is not medically necessary. Although subject to some
dispute, at least two federal district courts have also determined that alleged
violations of the federal antikickback statute or Stark I and Stark II are
sufficient to state a claim for relief under the FCA. In addition to the civil
provisions of the FCA, the federal government can use several criminal statutes
to prosecute persons who submit false or fraudulent claims for payment to the
federal government.
 
 Other regulations
 
  Our operations are subject to various state hazardous waste and non-hazardous
medical waste disposal laws. Those laws do not classify as hazardous most of
the waste produced from dialysis services. Occupational Safety and Health
Administration regulations require employers to provide workers who are
occupationally subject to blood or other potentially infectious materials with
certain prescribed protections. These regulatory requirements apply to all
healthcare facilities, including dialysis facilities, and require employers to
make a determination as to which employees may be exposed to blood or other
potentially infectious materials and to have in effect a written exposure
control plan. In addition, employers are required to provide or employ
hepatitis B vaccinations, personal protective equipment, infection control
training, post-exposure evaluation and follow-up, waste disposal techniques and
procedures and engineering and work practice controls. Employers are also
required to comply with various record-keeping requirements. We believe we are
in material compliance with these laws and regulations.
 
  Some states have established certificate of need programs regulating the
establishment or expansion of healthcare facilities, including dialysis
facilities. We believe we are in material compliance with all applicable state
certificate of need laws.
 
  Although we believe we comply materially with current applicable laws and
regulations, our industry will continue to be subject to substantial
regulation, the scope and effect of which are difficult to predict. We make no
assurance as to whether our activities will be reviewed or challenged by
regulatory authorities in the future.
 
Competition
 
  A significant portion of the dialysis industry consists of many small,
independent facilities. The dialysis industry is highly competitive,
particularly in terms of acquiring existing dialysis facilities and developing
relationships with referring physicians. Competition for qualified physicians
to act as medical directors is also vigorous. We have also, from time to time,
experienced competition from former medical directors or referring physicians
who have opened their own dialysis facilities. A portion of our business
consists of monitoring and providing supplies for ESRD treatments in patients'
homes. Certain physicians also provide similar services, and if the number of
such physicians were to increase, our business, results of operations or
financial condition could be adversely affected.
 
  As the chart below indicates, the market share of the five largest multi-
facility providers has increased significantly over the last five years.
However, the absolute number of dialysis facilities owned by hospitals and
independent physicians has remained fairly constant.

  Large multi-facility dialysis providers that we compete with domestically for
acquisitions include Fresenius Medical Care, Gambro Healthcare, Inc., Renal
Care Group, Inc. and Everest Healthcare Services Corp. In addition, we estimate
that the major international multi-facility providers served only approximately
5% of all non-U.S. dialysis patients in 1998. Certain of our competitors have
substantially greater financial resources than us and may compete with us for
acquisitions and developments of facilities in markets targeted by us. There
are also a number of large healthcare providers that have entered or may decide
to enter the dialysis business. We cannot assure that our facilities will
continue to compete successfully with the facilities of these other companies.
 
Insurance
 
  We carry property and general liability insurance, professional liability
insurance and other insurance coverage in amounts deemed adequate by our
management. However, we cannot assure that any future claims will not exceed
applicable insurance coverage. Furthermore, we cannot assure that malpractice
and other liability insurance will be available at a reasonable cost or that we
will be able to maintain adequate levels of malpractice insurance and other
liability insurance in the future. Physicians practicing at our facilities are
required to maintain their own malpractice insurance, and our medical directors
maintain coverage for their individual private medical practices. We do,
however, provide insurance coverage for our medical directors with respect to
the performance of their duties as medical directors of our facilities.
 
Employees
 
  As of March 15, 1999, we had more than 12,300 employees, including a
professional staff of approximately 8,500 employees, a corporate and regional
staff of approximately 1,200 employees and a facilities support and maintenance
staff of approximately 2,600 employees. Approximately 8,600 of our employees
are employed on a full-time basis. A small number of our employees are party to
collective bargaining agreements. We have experienced limited union organizing
activity. However, in general, we believe that our labor relations are good.
 
Risk factors
 
  In addition to the other information set forth in this Form 10-K, you should
note the following risks related to our business.
 
 Dependence on Medicare and Medicaid--Future declines in reimbursement rates
will affect a substantial portion of our revenues.
 
  We are reimbursed for dialysis services primarily at fixed rates established
in advance under the Medicare ESRD program. Reductions in these rates could
have a material adverse effect on our net operating revenues and profits.
Approximately 51% of our net operating revenues during fiscal 1998 was funded
by Medicare. Since 1983, Congress has changed the Medicare composite
reimbursement rate from a national average of $138 per treatment in 1983 to a
low of $125 per treatment on average in 1986 and to approximately $126 per
treatment on average at present. We cannot predict whether future rate changes
will be made. Also, increases in operating costs that are subject to inflation,
such as labor and supply costs, may occur without a compensating increase in
reimbursement rates.
 
  Since June 1, 1989, the Medicare ESRD program has paid for the administration
of EPO to dialysis patients. Approximately 13% of our net operating revenues in
1998 was generated from EPO reimbursement through Medicare and Medicaid
programs. Consequently, EPO reimbursement through Medicare and Medicaid
programs significantly affects our net income. From time to time, EPO
reimbursement programs have been, and in the future may be, subject to various
legislative or administrative proposals to reduce the EPO reimbursement rate.
For example, HHS and the Clinton administration have endorsed a 10% reduction
in Medicare reimbursement for EPO. We cannot predict whether future rate or
reimbursement method changes will be made. If such changes are implemented,
they could have a material adverse effect on our business, results of
operations or financial condition.
 
 
                                       28
<PAGE>
 
  Medicare separately reimburses us for other outpatient prescription drugs
that we administer to dialysis patients at the rate of 95% of the actual
wholesale price of each drug. The Clinton administration has proposed a
reduction in the reimbursement rate for outpatient prescription drugs to 83% of
actual wholesale price. We cannot predict whether Congress will approve this
rate change, or whether other reductions in reimbursement rates for outpatient
prescription drugs will be made. If such changes are implemented, they could
have a material adverse effect on our business, results of operations or
financial condition.
 
  All of the states in which we operate dialysis facilities currently provide
benefits to qualified patients to supplement their Medicare entitlement.
Approximately 4% of our net operating revenues during fiscal 1998 were funded
by Medicaid or comparable state programs. The Medicaid programs are subject to
statutory and regulatory changes which may have the effect of decreasing
program payments, increasing costs or modifying the way we operate our dialysis
business.
 
  For more details, see the heading "The dialysis industry." Also see the
subheadings "Medicare reimbursement," "EPO reimbursement," "Other drugs and
services delivered at centers" and "Medicaid reimbursement" under the heading
"Sources of revenue reimbursement."
 
 Possible changes in Medicare's method of reimbursement--The inclusion in the
Medicare composite reimbursement rate of certain services which currently are
separately reimbursed or the change to a capitated reimbursement system could
have a material adverse effect on our revenues and profits.
 
  We cannot predict whether certain services, for which we currently are
reimbursed separately, may in the future be included in the Medicare composite
rate. If, in the future, Medicare were to include in its composite
reimbursement rate any of the ancillary services presently reimbursed
separately, we would not be able to seek separate reimbursement for these
services. This would adversely affect our results of operations to the extent a
corresponding increase was not provided in the Medicare composite rate.
 
  HCFA already has initiated a pilot demonstration project to test the
feasibility of allowing managed care plans to participate in the Medicare ESRD
program on a capitated basis. Under a capitated plan we would receive a fixed
periodic payment for servicing all of our Medicare-eligible ESRD patients
regardless of certain fluctuations in the number of services provided in that
period or the number of patients treated.
 
 Other sources of reimbursement--Restrictions on our ability to charge for
current services at current rates could materially affect our business.
 
  Approximately 44% of our net operating revenues during fiscal 1998 were from
sources other than Medicare and Medicaid. These sources include payments from
third-party, non-government payors, at rates that generally exceed the Medicare
and Medicaid rates, payments from hospitals which we contract with to provide
inpatient dialysis treatments and payments from governments and private payors
in overseas markets. Any restriction on our ability to charge for our domestic-
market services at rates in excess of those paid by Medicare would adversely
affect our business, results of operations or financial condition. We are also
a party to nonexclusive agreements with certain third-party payors, and the
termination of certain of these agreements could have an adverse effect on our
business, results of operations or financial condition.
 
 Source of EPO--Only one company manufactures EPO and interruption of supply or
cost increases could materially affect our business.
 
  EPO is produced by a single manufacturer, Amgen Corporation. In the future,
Amgen may be unwilling or unable to supply us with EPO. Additionally, shortages
in the raw materials or other resources necessary to manufacture EPO, or simply
an arbitrary decision on the part of this sole supplier, may result in an
increase in the wholesale price of EPO. Interruptions of the supply of EPO or
increases in the price we pay for EPO could have a material adverse effect on
our financial condition as well as our ability to provide appropriate care to
our patients.
 
                                       29
<PAGE>
 
 Operations subject to government regulation--Our failure to meet current or
future government regulations could cause us to incur sanctions or could
prevent us from participating in certain government programs or operating in
certain geographical areas.
 
  Our dialysis operations are subject to extensive federal, state and local
governmental regulations in the U.S. and to extensive government regulation in
virtually every country in which we operate. U.S. and non-U.S. regulations are
designed to accomplish the same objectives: the provision of quality healthcare
for patients, the maintenance of occupational, health, safety and environmental
standards and the provision of accurate reporting and billing for government
payments and/or reimbursement. Our business would be adversely impacted by any
loss of federal certifications, authorization to participate in the Medicare or
Medicaid programs, or licenses under the laws of any state or governmental
authority in which we generate substantial revenue. Our industry will continue
to be subject to intense governmental regulation at the state and federal
levels, the scope and effect of which are difficult to predict. This regulation
could adversely impact us in a material way. In addition, we periodically may
be reviewed or challenged by various governmental authorities which could have
a material adverse effect on our business, results of operations or financial
condition.
 
  In addition, each foreign country in which we operate has its own payment and
reimbursement rules and procedures. Our failure to understand these
reimbursement systems could cause us to assess the performance of our
operations in other countries incorrectly. Some countries prohibit ownership of
healthcare providers by foreign interests or establish other regulatory
barriers to direct ownership by foreign companies. Failure to comply with these
regulations could have a material adverse effect on our business, results of
operations or financial condition. In addition, the relationships we have
structured, or may structure in the future, to overcome these regulatory
barriers may be challenged. For more details, see the subheading "International
regulation" under the heading "Government regulation."
 
  . Our failure to comply with fraud and abuse statutes could result in
    sanctions
 
  Neither our arrangements with the medical directors of our facilities nor the
minority ownership interests of referring physicians in certain of our dialysis
facilities meet all of the requirements of published safe harbors to the
illegal remuneration provisions of the Social Security Act and similar state
laws. These laws impose civil and criminal sanctions on persons who receive or
make payments for referring a patient for treatment that is paid for in whole
or in part by Medicare, Medicaid or similar state programs. Transactions
structured within published safe harbors are deemed not to violate these
provisions. Transactions that do not fall within a relevant safe harbor may be
subject to greater scrutiny by enforcement agencies. We could in the future be
required to change our practices or relationships with our medical directors or
with referring physicians holding minority ownership interests or could
otherwise be materially affected by any challenge under these statutes.
 
  California law prohibits a physician from making referrals for laboratory
services to entities with which they (or their immediate family members) have a
financial interest. We currently operate a large number of facilities in
California which account for a significant percentage of our business. It is
possible that the California statute could apply to laboratory services
incidental to dialysis services. If so, we would be required to restructure
some relationships with referring physicians who serve as medical directors of
our facilities and with the physicians who hold minority interests in some of
our facilities. We also provide laboratory services incidental to dialysis
services in many other states which have fraud and abuse statutes regulating
our relationships with physicians. For more details, see the subheadings "Fraud
and abuse under federal law" and "Fraud and abuse under state law" under the
heading "Government regulation."
 
  . Our practices may be subject to challenge under Stark I and Stark II
 
  Stark I restricts physicians from making referrals for clinical laboratory
services to entities with which they or their immediate family members have a
"financial relationship." It is unclear whether certain laboratory services
that we provide, which are incidental to dialysis services, fall within the
Stark I prohibition. Stark II restricts physicians from making referrals for
certain "designated health services" to entities with which they or their
immediate family members have a "financial relationship." It is unclear whether
some of the services which we provide fall within the Stark II prohibitions.
 
                                       30
<PAGE>
 
  Violations of Stark I and Stark II are punishable by civil penalties, which
may include exclusion or suspension of the provider from future participation
in Medicare and Medicaid programs and substantial fines. It is possible that
our practices might be challenged under these laws. For more details, see the
subheading "Stark I/Stark II" under the heading "Government regulation."
 
 Reimbursement of transportation costs--ESRD patients may not be able to use
our services if state programs stop reimbursing their transportation costs.
 
  At present, ESRD patients eligible for the Medicaid programs of certain
states, including California, are reimbursed for their transportation costs
relating to ESRD treatments. If this practice is changed or deemed to violate
applicable federal or state law, our patients may no longer receive this
service, and we cannot predict the effect this would have on the desire or
ability of patients to use our services.
 
 Investigations--We continuously are subject to regulatory scrutiny and
payments of revenues under investigation may be suspended and possibly never
collected.
 
  In the ordinary course of business, our operations continuously are subject
to regulatory scrutiny, supervision and control. This regulatory scrutiny often
includes inquiries, investigations, examinations, audits, site visits and
surveys, some of which may be non-routine. If we are found to have engaged in
improper practices, we could be subject to civil, administrative, or criminal
fines, penalties or restitutionary relief, and reimbursement authorities could
also seek our suspension or exclusion from participation in their programs.
 
  Our Florida-based laboratory subsidiary is the subject of a third-party
carrier review relating to certain claims submitted by us for Medicare
reimbursement. We understand that similar reviews have been undertaken with
respect to other providers' laboratory activities in Florida and elsewhere. The
carrier has alleged that 99.3% of the tests performed by this laboratory for
the review period it initially identified, from January 1995 to April 1996,
were not properly supported by the prescribing physicians' medical
justification. The carrier subsequently requested billing records with respect
to the additional period from May 1996 to March 1998. The carrier has issued a
formal overpayment determination in the amount of $5.6 million and has
suspended all payments of claims related to this laboratory. The carrier has
withheld approximately $11 million to date. In addition, the carrier has
informed the local offices of the DOJ and HHS of this matter. In February 1999,
our Florida-based laboratory subsidiary filed a complaint against the carrier
and HHS seeking a court order to lift the payment suspension. Any determination
adverse to us in this, or other potential, future investigations, could have an
adverse impact on our business, results of operations or financial condition.

the heading "Government regulation."
 
 Risks inherent in growth strategy--The acquisition and development of
additional dialysis facilities vital to our business strategy may strain our
existing resources and present integration problems or may never be completed.
 
  Our business strategy depends significantly on our ability to acquire or
develop, and successfully integrate, additional dialysis facilities. This
strategy subjects us to the risk that:
 
  . Suitable acquisition candidates may not be available;
 
  . We may not be able to consummate future acquisitions on acceptable terms;
 
  . We may not be able to integrate future acquisitions successfully;
 
  . We may be inaccurate in assessing the value, strengths and weaknesses of
    acquisition candidates;
 
  . We may be inaccurate in identifying suitable locations to develop
    additional facilities;
 
  . Businesses that we acquire may never achieve revenues and profitability
    that justify our investment in them; and
 
  . Additional financing may not be available to finance future acquisitions.
 
                                       31
<PAGE>
 
  To the extent that we are unable to acquire or develop facilities in a cost-
effective manner, our ability to expand our business and enhance our results of
operations and financial condition could be adversely affected. In addition,
integrating acquired operations, particularly newly acquired regional networks
and large scale acquisitions, such as our acquisition of RTC, present a
significant challenge and may lead to unanticipated costs or a diversion of
management's attention from day-to-day operations. Despite the pooling of
TRCH's and RTC's historical operating results, we have conducted operations as
a combined entity only since February 1998. This pooling of the historic
results of operations and financial condition of TRCH and RTC on a stand-alone
basis may differ from our actual combined results in the future.
 
  Our growth is expected to place significant demands on our financial and
management resources and will require us to develop further the management
skills of our managers and supervisors, and to continue to train, motivate and
effectively manage our employees. There are risks that:
 
  . Our operations and future acquisitions may require additional personnel,
    assets and cash expenditures and we may not be able to manage effectively
    the expansion of our operations;
 
  . We may not be able to anticipate and respond to all of the changing
    demands that our expanding operations, including our acquisition of RTC,
    will and could continue to have on our management, and information,
    financial and operating systems; and
 
  . Acquisitions could result in disruptions and unanticipated expenses.
 
  Our failure to meet the challenges of expansion and to manage our prior and
future growth could have an adverse effect on our business, results of
operations or financial condition. For more details, see the heading "Business
strategy."
 
 Dependence on physician referrals--The loss of key referring physicians could
reduce our patient base and our revenues.
 
  We depend upon referrals of ESRD patients by physicians specializing in
nephrology and practicing in the communities we serve. As generally is true in
the dialysis industry, one or a few physicians refer all or a significant
portion of the patients at each facility. The loss of one or more key referring
physicians at a particular facility could have a material adverse effect on the
operations of that facility and could adversely affect our business, results of
operations or financial condition. Referring physicians own minority interests
in certain of our dialysis facilities. If these interests are deemed to violate
applicable federal or state law, these physicians may be forced to dispose of
their ownership interests. We cannot predict the effect these dispositions
would have on our continuing relationships with these physicians or our
business. For more details, see the subheading "Physician relationships" under
the heading "Operations."
 
 Operations outside the United States--Certain attributes of foreign companies
may make their integration into our operations more difficult.
 
  We are entering certain international markets for the first time and there
can be no assurance that we will be able to integrate international
acquisitions effectively. Certain attributes of foreign companies and their
operations may make their integration into our operations more difficult. These
attributes include:
 
  . Differences in accepted clinical standards and practices;
 
  . Differences in management styles and practices;
 
  . The unfamiliarity of foreign companies with United States generally
    accepted accounting principles; and
 
  . The limiting of employee discharges and disciplinary actions in
    accordance with local laws.
 
  Any failure to integrate efficiently foreign acquisitions or to realize
expected synergies and cost savings could have a material adverse effect on our
business, results of operations and financial condition.
 
                                       32
<PAGE>
 
 Outstanding debt--The large amount of our total outstanding debt and our
obligation to service that debt could divert necessary funds from operations,
limit our ability to obtain financing for future needs and expose us to
interest rate risks, and covenants in our credit facilities may prevent us from
taking advantage of business opportunities.
 
  We are highly leveraged, which means that the amount of our outstanding debt
is large compared to the net book value of our assets, and have substantial
repayment obligations under our outstanding debt. As of December 31, 1998 we
had:
 
  . Total consolidated debt of approximately $1.25 billion; and
 
  . Stockholders' equity of approximately $481.8 million.
 
  In addition, as of December 31, 1998, our borrowing availability under our
credit facilities was approximately $596.4 million.
 
  Our credit facilities contain numerous financial and operating covenants that
limit our ability, and the ability of most of our subsidiaries, to undertake
certain transactions. These covenants require that we meet certain interest
coverage, net worth and leverage tests. The indentures governing our 7%
convertible subordinated notes and RTC's 5 5/8% convertible subordinated notes,
collectively referred to throughout this Form 10-K as our notes, and our credit
facilities permit us and our subsidiaries to incur or guarantee additional
debt, subject to certain limitations in the case of the credit facilities.
 
  Our level of debt and the limitations imposed on us by our debt agreements
could have other important consequences to our stockholders and noteholders,
including the following:
 
  . We will have to use a portion of our cash flow from operations for debt
    service, rather than for our operations;
 
  . We may not be able to obtain additional debt financing for future working
    capital, capital expenditures, acquisitions or other corporate purposes;
 
  . The debt under our credit facilities is at a variable interest rate,
    making us vulnerable to increases in interest rates; and
 
  . We could be less able to take advantage of significant business
    opportunities, such as acquisitions, and react to changes in market or
    industry conditions.
 
 Purchase of notes upon a change of control--We may not have the ability to
raise the funds necessary to satisfy the change of control covenants included
in the indentures governing our notes.
 
  Under the indentures governing our notes, upon the occurrence of a change of
control, as defined in the indentures, our noteholders may require us to
repurchase all or a portion of their notes at 100% of the principal amount of
the notes plus accrued and unpaid interest and any liquidated damages to the
date of purchase. If a change of control occurs, we may not be able to pay the
repurchase price for all of the notes submitted for repurchase. In addition,
the terms of some of our existing debt agreements, including our credit
facilities, prohibit us from purchasing any notes until all debt under these
agreements is paid in full. Our future credit agreements or other agreements
may contain similar provisions. If a change of control occurs while we are
prohibited from purchasing the notes, we could seek the consent of our lenders
to the purchase of the notes. We could also attempt to refinance the borrowings
that contain the prohibition. If we do not obtain a consent or repay the
borrowings, we would remain prohibited from purchasing the notes. In that case,
our failure to purchase submitted notes would constitute an event of default
under the indentures. This, in turn, would constitute a further default under
certain of our existing or future debt agreements, including our credit
facilities. In that case, certain persons could declare all debt under the
notes or our credit facilities due and payable.
 
                                       33
<PAGE>
 
  Our inability to pay all debt under our credit facilities, if accelerated,
would constitute an event of default under the indentures governing our notes,
which could accelerate all debt under the indentures. In the event of a change
of control, we might not be able to refinance our credit facilities, which
would allow us to repay all tendered notes, and we might not have sufficient
assets to satisfy all of our obligations under our credit facilities and the
notes. In addition to the above, if we undergo a change of control portions of
our debt, including our credit facilities, may be accelerated or we may be
required to repurchase such debt.
 
 Antitakeover provisions--Provisions in our charter documents may deter a
change of control which our stockholders may otherwise determine to be in their
best interests.
 
  Our certificate of incorporation and bylaws and the Delaware General
Corporation Law, or DGCL, include provisions which may have the effect of
deterring hostile takeovers, delaying or preventing changes in control or
changes in our management, or limiting the ability of our stockholders to
approve transactions that they may otherwise determine to be in their best
interests. These provisions include:
 
  . A provision requiring that any action required or permitted to be taken
    by our stockholders must be effected at a duly called annual or special
    meeting of our stockholders and may not be effected by written consent;
 
  . A provision requiring at least 60 days' advance notice by a stockholder
    of a proposal or director nomination which such stockholder desires to
    present at any annual or special meeting of stockholders; and
 
  . A provision granting our board of directors the authority to issue up to
    five million shares of preferred stock and to determine the rights and
    preferences of the preferred stock without the need for further
    stockholder approval. The existence of this "blank-check" preferred stock
    could make more difficult or discourage an attempt to obtain control of
    us by means of a tender offer, merger, proxy contest or otherwise.
    Furthermore, this "blank-check" preferred stock may have other rights,
    including economic rights, senior to our common stock, and, therefore,
    issuance of the preferred stock could have an adverse effect on the
    market price of our common stock.
 
  We may, in the future, adopt other measures that may have the effect of
delaying, deferring or preventing an unsolicited takeover, even if such a
change in control were at a premium price or favored by a majority of
unaffiliated stockholders. Certain of these measures may be adopted without any
further vote or action by our stockholders.
 
 Year 2000 issues--We may experience material unanticipated negative
consequences beginning in the year 2000 due to undetected computer defects.
 
  The following discussion about the implementation of our "Year 2000," or Y2K
program, the costs expected to be associated with the program and the results
we expect to achieve constitute forward-looking information. As noted below,
there are many uncertainties involved in the Y2K issue, including the extent to
which we will be able to provide adequately for contingencies that may arise,
as well as the broader scope of the Y2K issue as it may affect third parties.
Accordingly, the costs and results of our Y2K program and the extent of any
impact on our results of operations could vary materially from those disclosed
below.
 
  The Y2K issue concerns the potential exposures related to the automated
generation of misinformation resulting from the use of computer programs which
have been written using two digits, rather than four, to define the applicable
year of business transactions. We are not currently aware of any material
operational issues associated with preparing our internal computer systems,
facilities and equipment for Y2K. We cannot assure you, however, due to the
overall complexity of the Y2K issues and the uncertainty surrounding third
party responses to Y2K issues that we will not experience material
unanticipated negative consequences and/or material costs caused by undetected
errors or defects in our or third party systems or by our failure to adequately
prepare for the results of such errors or defects. The impact of such
consequences could have a material adverse effect on our business, financial
condition or results of operations.
 
                                       34
<PAGE>
 
  The extent and magnitude of the Y2K problem as it will affect us, both
before, and for some period after, January 1, 2000, are difficult to predict or
quantify for a number of reasons. Among the most important are our lack of
control over systems that are used by the third parties who are critical to our
operations, such as telecommunications and utilities companies and governmental
and non-governmental payors, the complexity of testing interconnected networks
and applications that depend on third-party networks and the uncertainty
surrounding how others will deal with liability issues raised by Y2K-related
failures. Moreover, the estimated costs of implementing our plans for fixing
Y2K problems do not take into account the costs, if any, that might be incurred
as a result of Y2K-related failures that occur despite our implementation of
these plans.
 
  For more details see the subheading "Year 2000 considerations" under the
heading "Liquidity and capital resources," in "Item 7. Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
  Goodwill amortization--If our assumptions regarding the beneficial life of
our goodwill prove to be inaccurate, or subsequently change, our current
earnings may be overstated and future earnings may be understated.
 
  Our balance sheet has an amount designated as "goodwill" that represents 49%
of our assets and 197% of our stockholders' equity at December 31, 1998.
Goodwill arises when an acquiror pays more for a business than the fair value
of the tangible and separately measurable intangible net assets. Generally
accepted accounting principles require that goodwill and all other intangible
assets be amortized over the period benefited. The current blended average
useful life is 34 years for our goodwill and 21 years for all of our intangible
assets that relate to business combinations. We have determined that most
acquisitions after December 31, 1996 will continue to provide a benefit to us
for no less than 40 years after the acquisition. In making this determination,
we have reviewed with our independent accountants the significant factors which
we considered in arriving at the consideration to be paid for, and the expected
period of benefit from, acquired businesses.
 
  If the factors we considered, and which give rise to a material portion of
our goodwill, result in an actual beneficial period which is shorter than our
determined useful life, earnings reported in periods immediately following
certain acquisitions would be overstated. In addition, in later years, we would
be burdened by a continuing charge against earnings without the associated
benefit to income. Earnings in later years could also be affected significantly
if we subsequently determine that the remaining balance of goodwill has been
impaired.
 
 Forward-looking statements
 
  This Form 10-K contains statements that are forward-looking statements within
the meaning of the federal securities laws. These include statements about our
expectations, beliefs, intentions or strategies for the future, which we
indicate by words or phrases such as "anticipate," "expect," "intend," "plan,"
"will," "believe" and similar language. These statements involve known and
unknown risks, including risks resulting from economic and market conditions,
the regulatory environment in which we operate, competitive activities and
other business conditions, and are subject to uncertainties and assumptions set
forth elsewhere in this Form 10-K. Our actual results may differ materially
from results anticipated in these forward-looking statements. We base our
forward-looking statements on information currently available to us, and we
assume no obligation to update these statements.
 
Item 2. Properties.
 
  Thirteen of our dialysis facilities are operated on properties that we own.
The remaining 524 dialysis facilities that we operate are located on premises
leased by us or our general partnerships, limited liability companies or
subsidiary corporations or by entities that we manage. We lease at fair market
value certain facilities from entities in which referring physicians hold an
interest. Our leases generally cover periods from
 
                                       35
<PAGE>
 
five to ten years and typically contain renewal options of five to ten years at
the fair rental value at the time of renewal or at rates subject to consumer
price index increases since the inception of the lease. Our facilities range in
size from approximately 500 to 15,900 square feet, with an approximate average
size of 4,900 square feet. We operate our corporate headquarters in
approximately 35,800 square feet of office space in Torrance, California which
we currently lease for a term expiring in 2008. Our general accounting office
in Tacoma, Washington, is leased for a term expiring in 2000. We have entered
into an additional ten year lease in Tacoma, Washington for an 80,000 square
foot facility beginning in April 1999. We maintain a 43,000 square foot
facility in Berwyn, Pennsylvania for additional billing and collections
purposes and limited corporate and regional staff. The Berwyn lease expires in
2001. Our Florida-based laboratory is located in a 30,000 square foot facility
owned by us, with a ground lease, and our Minnesota-based laboratory is located
in a 9,500 square foot facility leased by us.
 
  Certain of our facilities are operating at or near capacity. However, we
believe that we have adequate capacity within most of our existing facilities
to accommodate significantly greater patient volume through increased hours
and/or days of operation, or through the addition of dialysis stations at a
given facility upon obtaining appropriate governmental approvals. In addition,
we have the ability to build de novo facilities if existing facilities reach
capacity. With respect to relocating facilities or building de novo facilities,
we believe that we can generally lease space at economically reasonable rates
in the area planned for each of these facilities. Expansion or relocation of
our facilities would be subject to review for compliance with conditions
relating to participation in the Medicare ESRD program. In states that require
a certificate of need, approval of our application generally would be necessary
for expansion or relocation.
 
Item 3. Legal Proceedings.
 
  Following the announcement on February 18, 1999 of our preliminary results
for the fourth quarter of fiscal 1998 and the full year then ended, several
class action lawsuits were filed against us and certain of our officers in the
U.S. District Court for the Central District of California. The complaints are
similar and allege violations of federal securities laws arising from alleged
false and misleading statements primarily regarding our accounting for the
integration of RTC into TRCH and request unspecified monetary damages. We
believe that all of the claims are without merit and we intend to defend
ourselves vigorously. We anticipate that the attorneys' fees and related costs
of defending these lawsuits should be covered primarily by our directors and
officers insurance policies and we believe that any additional costs will not
have a material impact on our financial condition, results of operations or
cash flows.
 
  In February 1999, our Florida-based laboratory subsidiary filed a complaint
against HHS and a third-party carrier. The carrier has suspended all payments
for certain claims submitted by the laboratory for Medicare reimbursement
pending a review of these claims. The complaint seeks a court order lifting the
payment suspension. See the subheading "Florida laboratory payment dispute"
under the heading "Government regulation."
 
  In addition, we are subject to claims and suits in the ordinary course of
business for which we believe we will be covered by insurance. We do not
believe that the ultimate resolution of these additional pending proceedings,
whether the underlying claims are covered by insurance or not, will have a
material adverse effect on our financial condition, results of operations or
financial condition.

  The closing price of our common stock on March 15, 1999 was $9.25 per share.
As of March 15, 1999 there were approximately 1,937 holders of our common stock
named as holders of record by The Bank of New York, our registrar and transfer
agent. Since our recapitalization in 1994, we have not declared or paid cash
dividends to holders of our common stock. We do not anticipate paying any cash
dividends in the foreseeable future. We are subject to certain restrictions on
our ability to pay dividends on our common stock. For more details, see the
heading "Liquidity and capital resources" under "Item 7. Management's

 (1) In 1995, we changed our fiscal year end to December 31 from May 31.
 
 (2) Our recapitalization in 1994 and subsequent acquisitions have had a
     significant impact on our capitalization and equity securities and on our
     results of operations. Consequently, the balance sheet data as of May 31,
     1995 and as of December 31, 1995, 1996, 1997 and 1998 and the income
     statement data for the fiscal year ended May 31, 1995, for the seven
     months ended December 31, 1995, and the years ended December 31, 1996,
     1997 and 1998 are not directly comparable to corresponding information as
     of prior dates and for prior periods, respectively.
 
 (3) General and administrative expenses for the fiscal year ended May 31, 1994
     include overhead allocations by our former parent of $1,458,000 for the
     period June 1993 through February 1994. No overhead allocation was made
     for the period from March 1994 through our recapitalization in 1994 at
     which time we began to record general and administrative expenses as
     incurred on a stand-alone basis. General and administrative expenses for
     the fiscal year ended May 31, 1994 also reflect $458,000 in expenses
     relating to a terminated equity offering. During the first quarter of 1998
     we recorded an expense of $79,435,000 for merger and related costs
     associated with the RTC merger and during the second quarter we recorded a
     charge in interest expense of $9,823,000 to terminate interest rate swap
     agreements on debt that were refinanced.
 
 (4) In December 1995, we recorded an extraordinary loss of $2,555,000, or
     $0.09 per share, net of tax, on the early extinguishment of debt. In July
     and September 1996, we recorded a combined extraordinary loss of
     $7,700,000 or $0.10 per share net of tax, on the early extinguishment of
     debt. At the time of our merger with RTC we paid off their existing
     revolving credit agreement and the remaining unamortized deferred
     financing costs, net of tax, of $2,812,000 or approximately $0.04 per
     share, was included as an extraordinary loss in 1998. In April 1998 we
     replaced our existing $1.05 billion credit facilities with a combined
     total of $1.35 billion in two senior credit facilities. As a result of
     this refinancing, the remaining net deferred financing costs, net of tax,
     of $9,932,000 or approximately $0.12 per share, was included as an
     extraordinary loss in 1998. See Note 8 of our consolidated financial
     statements.
 
     In the first quarter of 1998 we adopted Statement of Position No. 98-5,
     Reporting on the Costs for Start-up Activities, or SOP 98-5, which
     requires that pre-opening and organization costs previously treated as
     deferred costs should be expensed as incurred. As a result all existing
     remaining unamortized deferred pre-opening and organizational costs was
     taken as a charge, net of tax, of $6,896,000 or approximately $0.08 per
     share, as a cumulative effect of a change in accounting principle. See our
     consolidated financial statements and related notes.
 
 (5) See additional income per share information in our consolidated statements
     of income.
 
 (6) Mandatorily redeemable common stock represents shares of common stock
     issued in certain acquisitions subject to put options that terminated upon
     the completion of our initial public offering.
 
 (7) In connection with our recapitalization in 1994, we paid a special
     dividend to Tenet Healthcare Corporation, or Tenet, of $81.7 million,
     including $75.5 million in cash.
 
 (8) The consolidated income statement data combine our results of operations
     for the years ended May 31, 1994 and 1995, the seven months ended December
     31, 1994 and 1995 and the years ended December 31, 1995, 1996 and 1997
     with RTC's results of operations for the years ended December 31, 1993 and
     1994, the six months ended December 31, 1994 and 1995 and the years ended
     December 31, 1995, 1996 and 1997, respectively.
 
 (9) The consolidated balance sheet data combines our balance sheet as of May
     31, 1994 and 1995 and December 31, 1995, 1996 and 1997 with RTC's balance
     sheet as of December 31, 1993, 1994, 1995, 1996 and 1997, respectively.
 
(10) The ratio of earnings to fixed charges is computed by dividing fixed
     charges into earnings. Earnings is defined as pretax income from
     continuing operations adjusted by adding fixed charges and excluding
     interest capitalized during the period. Fixed charges means the total of
     interest expense and amortization of financing costs and the estimated
     interest component of rental expense on operating leases.

Item 7. Management's Discussion and Analysis of Financial Condition and Results
of Operations.
 
  The following should be read in conjunction with our consolidated financial
statements and the related notes contained elsewhere in this Form 10-K.
 
Background
 
  Our wholly-owned subsidiary TRC, formerly Medical Ambulatory Care, Inc., was
organized in 1979 by Tenet, formerly National Medical Enterprises, Inc., to own
and operate Tenet's hospital-based dialysis services as freestanding dialysis
facilities and to acquire and develop additional dialysis facilities in Tenet's
markets. TRCH was organized to facilitate the 1994 sale by Tenet of
approximately 75% of its ownership interest to DLJ Merchant Banking Partners,
L.P., or DLJMB, and certain of its affiliates, our management and certain
holders of our debt securities.
 
  In connection with our recapitalization in 1994, we paid a special dividend
to Tenet out of the net proceeds from (a) the issuance of units consisting of
$100 million in principal amount at maturity of 12% senior subordinated
discount notes due 2004, which were issued at approximately 70% of par, and
1,000,000 shares of common stock and (b) borrowing under TRC's revolving credit
facility. We raised additional capital to fund the continuation of our growth
strategy through an initial public offering, or IPO, in October 1995 in which
we raised gross proceeds of $107 million. Concurrent with the IPO, we listed
our common stock on the New York Stock Exchange under the symbol "TRL."
Subsequent to the IPO, we changed our fiscal year end from May 31 to December
31.
 
  We raised additional capital to further our growth strategy with two
secondary stock offerings in April and October of 1996 which raised gross
proceeds to us of approximately $135 million. In October of 1996 we increased
our credit facility from $130 million to $400 million. With the proceeds from
the IPO, the April 1996 secondary offering and the credit facility, we were
able to complete the early retirement of the discount notes. In October 1997
and April 1998, we increased our credit facility to an aggregate of $1.05
billion and $1.35 billion respectively in two bank facilities. In November
1998, we sold $345 million of our 7% convertible subordinated notes.
 
  Following our recapitalization in 1994, we implemented a focused strategy to
increase net operating revenues per treatment and improve operating income
margins. We have significantly increased per-treatment revenues through
improved pricing, the addition of in-house clinical laboratory services,
increased utilization of ancillary services and the addition of in-house
pharmacy services and other ancillary programs. To improve operating income, we
began a systematic review of our vendor relations leading to the renegotiation
of a number of supply contracts and insurance arrangements that reduced
operating expenses. In addition, we have focused on improving facility
operating efficiencies and leveraging corporate and regional management. These
improvements have been offset in part by increased amortization of goodwill and
other intangible assets relating to our acquisitions (all of which have been
accounted for as purchase transactions, except the merger with RTC) and start-
up expenses related to de novo developments.
 
  On February 27, 1998, we acquired RTC in a stock for stock transaction valued
at approximately $1.3 billion. The transaction was accounted for as a pooling
of interests. Accordingly, our consolidated financial statements have been
restated to include RTC for all periods presented.
 
Net operating revenues
 
  Net operating revenues are derived primarily from four sources: (a)
outpatient facility hemodialysis services; (b) ancillary services, including
EPO administration and other intravenous pharmaceuticals, clinical laboratory
services, oral pharmaceutical products and other ancillary services; (c) home
dialysis services and related products; (d) inpatient hemodialysis services
provided to hospitalized patients pursuant to arrangements with hospitals; and
(e) international operations. Additional revenues are derived from the
provision of dialysis facility management services to certain subsidiaries and
affiliated and unaffiliated dialysis centers. Our dialysis
 
                                       40
<PAGE>
 
and ancillary services are reimbursed primarily under the Medicare ESRD program
in accordance with rates established by HCFA. Payments are also provided by
other third party payors, generally at rates higher than those reimbursed by
Medicare for up to the first 33 months of treatment as mandated by law. Rates
paid for services provided to hospitalized patients are negotiated with
individual hospitals. For the years ended December 31, 1996, December 31, 1997
and December 31, 1998, approximately 60%, 56% and 51%, respectively, and 4%, 5%
and 4%, respectively of our net patient revenues were derived from
reimbursement under Medicare and Medicaid, respectively. For more information,
see the subheading "Sources of revenue reimbursement" under "Item 1. Business."

Year ended December 31, 1998 compared to year ended December 31, 1997
 
  Net operating revenues. Net operating revenues consist primarily of dialysis
and ancillary fees from patient treatments and reflect the amounts expected to
be realized from governmental third-party payors, patients, hospitals and
others for services provided. Net operating revenues increased $443,897,000 to
$1,204,894,000 for the year ended December 31, 1998 from $760,997,000 for the
year ended December 31, 1997, representing a 58.3% increase. Of this increase,
$341,197,000 was due to increased treatments from acquisitions, existing
facility growth and from de novo developments. The remaining increase of
$102,700,000 resulted from an increase in net operating revenues per treatment
which increased from $224.37 in 1997 to $245.28 in 1998. The increase in net
operating revenues per treatment was attributable to increased ancillary
services utilization of $44,581,000, primarily in the administration of EPO of
$36,147,000, the overall impact of a rate increase of $32,090,000, $21,912,000
resulting from an increase in the number of services reimbursed by private
payors, who pay at higher rates, stemming from HCFA's extension of private
payor primary reimbursement obligations for an additional twelve-month period,
and expanded laboratory services extended to former RTC facilities of
$4,117,000.
 
  Facility operating expenses. Facility operating expenses consist of costs and
expenses specifically attributable to the operation of dialysis facilities,
including operating and maintenance costs of such facilities, equipment, direct
labor, and supply and service costs relating to patient care. Facility
operating expenses increased $261,676,000 to $772,666,000 in 1998 from
$510,990,000 in 1997 and as a percentage of net operating revenues, facility
operating expenses decreased to 64.1% in 1998 from 67.1% in 1997. This decrease
primarily was due to decreases in labor and pharmaceutical costs as a
percentage of revenues partially offset by an increase in other facility
expenses, consisting primarily of rent and medical director fees.

  General and administrative expenses. General and administrative expenses
include headquarters expense and administrative, legal, quality assurance,
information systems and centralized accounting support functions. General and
administrative expenses increased $25,730,000 to $75,829,000 in 1998 from
$50,099,000 in 1997, and as a percentage of net operating revenues, general and
administrative expenses decreased to 6.3% for 1998 from 6.6% in 1997. The
decrease of 0.3% of net operating revenues, or approximately $3,493,000, is a
result of the elimination of duplicate corporate staff and efficiencies
achieved from the RTC merger of $4,100,000 and revenue growth and economies of
scale achieved by the leveraging of corporate staff across a higher revenue
base of $2,693,000, offset by bonus payments of $3,300,000 made in connection
with our merger with RTC.
 
  Provision for doubtful accounts. The provision for doubtful accounts is
influenced by the amount of net operating revenues generated from non-
governmental payor sources in addition to the relative percentage of accounts
receivable by aging category. The provision for doubtful accounts increased
$23,840,000 to $44,365,000 in 1998 from $20,525,000 in 1997. As a percentage of
net operating revenues, the provision for doubtful accounts increased to 3.7%
in 1998 from 2.7% in 1997. This increase was primarily due to an additional
allowance of $11,500,000, taken in the fourth quarter of 1998, as a result of
the most recent analysis of the remaining RTC accounts receivable that were on
the books as of December 31, 1997. The provision for doubtful accounts, as a
percentage of net operating revenues for 1998, before considering the
additional RTC allowance, was 2.7%.
 
  Depreciation and amortization. Depreciation and amortization increased
$37,425,000 to $92,028,000 in 1998 from $54,603,000 in 1997, and as a
percentage of net operating revenues, depreciation and amortization increased
to 7.6% in 1998 from 7.2% in 1997. This increase primarily was attributable to
accelerated depreciation associated with certain incompatible and duplicative
software as a result of the merger with RTC. For systems identified to be
abandoned, the remaining net book value, less depreciation to the expected date
of abandonment, which amounted to approximately $5,900,000, was charged to
merger and related costs.
 
  Merger and related expenses.
 
  Merger and related costs recorded during 1998 include transaction costs
associated with certain integration activities, and costs of employee severance
and amounts due under employment agreements and other compensation programs.
 
  A summary of merger and related costs and accrual activity through December
31, 1998 is as follows:

  Direct transaction costs consist primarily of investment banking fees, legal
and accounting costs and other costs, including the costs of consultants,
printing and registration, which were incurred by both TRCH and RTC in
connection with the merger. During the fourth quarter we concluded negotiations
pertaining to the amount of certain of these fees and subsequently we paid
these amounts.
 
                                       43
<PAGE>
 
Severance and employment costs were incurred for the following:
 
  . Severance pay. The RTC merger constituted a constructive termination of
    employment under various preexisting employment contracts with RTC
    officers. Terminated RTC officers were entitled to severance payments and
    tax gross-up payments of approximately $6,500,000. In addition,
    approximately 80 employees of RTC were informed that their positions
    would be eliminated. Most of these employees were formerly located in
    RTC's administrative office and a laboratory under development. The
    terminations were structured over the integration period, which continued
    through the end of 1998. The accrued severance payments to these
    employees amounted to approximately $1,600,000. The remaining balance of
    severance costs of $600,000 was paid in the first quarter of 1999 and tax
    gross up payments of approximately $3,000,000 are expected to be paid in
    the second quarter of 1999.
 
  . Option exercises. Pre-existing terms of RTC stock option grants permitted
    the exercise of options by tender of RTC shares. Some of the RTC shares
    tendered had been held for less than six months by the option holders
    and, as required by Emerging Issues Task Force Issue 84-18, we recognized
    a noncash expense of approximately $16,000,000 equal to the difference
    between the exercise price of the options and the market value of the
    stock on the date of exercise. We also incurred approximately $600,000 of
    payroll tax related to the exercise of nonqualified stock options.
 
  . Bonuses. RTC and TRCH each awarded special bonuses as a result of the
    merger, paid in the first quarter in 1998, for which approximately
    $16,300,000 was included in merger and related costs.
 
  In connection with the RTC merger, we developed a plan which included
initiatives to integrate the operations of TRCH and RTC, eliminate duplicative
overhead, facilities and systems and improve service delivery. These
integration activities were commenced during the first quarter of 1998 and are
expected to be substantially completed by approximately July 1, 1999.
 
  We eliminated the following RTC departments: human resources, managed care,
laboratory, and all finance functions, with the exception of patient
accounting. The finance functions eliminated included payroll, financial
reporting and analysis, budgeting, general ledger, accounts payable, and tax
functions. The RTC human resources and managed care departments were
discontinued in Berwyn, Pennsylvania and consolidated with our respective
departments in our Torrance, California headquarters as of September 30, 1998.
All finance functions, with the exception of patient accounting, were
consolidated into our Tacoma, Washington business office as of December 31,
1998. RTC's laboratory, located in Las Vegas, Nevada, was closed prior to its
commencement of operation. All laboratory functions were consolidated into our
laboratories in Minnesota and Florida in February 1998.
 
  Costs to integrate operations included the following:
 
  . Laboratory restructuring. As part of our merger integration plan, we
    decided to restructure our laboratories. To optimize post-merger
    operations, we terminated a long-term management services agreement with
    a third party that provided full laboratory management on a contract
    basis. The termination fee of approximately $3,800,000 was negotiated in
    the first quarter of 1998. We also immediately halted development of
    RTC's new laboratory, which was not required for post-merger operations.
    The RTC laboratory, which was being developed in leased space, is now
    vacant and a new sublessee is being sought. As a result of this decision,
    previously capitalized leasehold improvements of $2,600,000 were
    expensed. Additionally, merger and related costs include approximately
    $1,000,000 of pre-opening start up costs incurred during the first
    quarter of 1998 relating to the terminated RTC laboratory and $1,500,000
    of remaining lease payments. The accrual for lease payments was not
    offset by any anticipated sublease income. No such income has been
    received to date and the remaining balance of this accrual at December
    31, 1998 was approximately $1,165,000.
 
  . Initial merger costs. Approximately $5,400,000 was expensed for
    integration activities which occurred at the time of the merger. These
    costs include a special training program held in March 1998 and attended
    by many TRCH and RTC employees, merger related travel costs, consultant
    costs and other costs attributed to the merger.

  The expected savings to be achieved from the elimination of general and
administrative expenses will come in the form of reduced compensation in the
future as follows:

</TABLE>
 
  No assurance can be given that we will achieve these savings.
 
  Additionally, as the merger has resulted in approximately $67,000,000 of non-
recurring cash expenses, there will be an ongoing impact to interest expense of
approximately $5,000,000 per year.
 
  Operating income. Operating income increased $17,038,000 to $141,818,000 in
1998 from $124,780,000 in 1997. As a percentage of net operating revenues,
operating income decreased to 11.8% in 1998 from 16.4% in 1997. This decrease
was due to the costs associated with the RTC merger. Operating income before
the merger costs increased to 18.3%, as a percentage of net operating revenues,
in 1998. This increase primarily was due to increased revenues, and a general
decrease in operating costs partially offset by the additional provision for
doubtful accounts recorded in the fourth quarter.
 
  Interest expense. Interest expense increased $44,590,000 to $72,804,000 in
1998 from $28,214,000 in 1997, and as a percentage of net operating revenues,
interest expense was 6.0% in 1998 and 3.7% in 1997. The increase in interest
expense primarily was due to an increase in borrowings made under our credit
facilities to fund acquisitions.
 
  Interest rate swap-early termination costs. In conjunction with the
refinancing of our credit facilities, two existing forward interest rate swap
agreements were canceled in April 1998. The early termination costs associated
with the cancellation of those swaps was $9,823,000.
 
  Interest income. Interest income is generated as a result of the short-term
investment of surplus cash from operations and excess proceeds from borrowings
under our credit facilities. Interest income increased $1,719,000 to $4,894,000
in 1998 from $3,175,000 in 1997. As a percentage of net operating revenues,
interest income remained at 0.4% for both years.
 
  Provision for income taxes. Provision for income taxes increased $1,368,000
to $41,580,000 in 1998 from $40,212,000 in 1997. The effective income tax rate
after minority interests increased to 73.1% in 1998 from 42.2% in 1997. The
overall increase in the effective tax rate primarily reflects non-deductible
merger and related expenses consisting of certain compensation costs and stock
issuance costs of $36,000,000 as well as non-deductible goodwill associated
with other acquired businesses. Before the non-deductible merger charges, the
effective tax rate after minority interests declined to 39.8% in 1998 from
42.2% in 1997 primarily due to the restructuring of our business in Argentina
to increase our consolidated tax deductible income by increasing equity and
reducing debt in Argentina.
 
  Minority interests. Minority interests represent the pretax income earned by
minority partners who directly or indirectly own minority interests in our
partnership affiliates and the net income in certain of our corporate
subsidiaries. Minority interests increased $2,661,000 to $7,163,000 in 1998
from $4,502,000 in 1997, and as a percentage of net operating revenues,
minority interest amounted to 0.6% for both years.
 
  Extraordinary item. On February 27, 1998, in conjunction with our merger with
RTC, we terminated RTC's revolving credit agreement and recorded all of the
remaining unamortized deferred financing costs as an extraordinary loss of
$2,812,000, net of income tax effect. In April 1998, in conjunction with
replacing our senior credit facilities, we also recorded all of the remaining
related unamortized deferred financing costs as an extraordinary loss of
$9,932,000, net of income tax effect.
 
                                       45

  Cumulative effect of change in accounting principle. Effective January 1,
1998, we adopted SOP 98-5. SOP 98-5 requires that pre-opening and
organizational costs incurred in conjunction with pre-opening activities
associated with our de novo facilities, which previously had been treated as
deferred costs and amortized over five years, should be expensed as incurred.
In connection with this adoption, we recorded a charge of $6,896,000, net of
income tax effect, as a cumulative effect of change in accounting principle.
 
 Year ended December 31, 1997 compared to year ended December 31, 1996
 
  Net operating revenues. Net operating revenues increased $262,973,000 to
$760,997,000 for the year ended December 31, 1997 from $498,024,000 for the
year ended December 31, 1996 representing a 52.8% increase. Of this increase,
$257,113,000 was due to increased treatments from acquisitions, existing
facility growth and de novo developments. The remainder was due to an increase
in net operating revenues per treatment which were $224.37 in 1997 compared to
$222.64 in 1996. The increase in net operating revenues per treatment was due
to increases in ancillary services utilization and in affiliated and
unaffiliated facility management fees.
 
  Facility operating expenses. Facility operating expenses increased
$166,810,000 to $510,990,000 in 1997 from $344,180,000 in 1996 and as a
percentage of net operating revenues, facility operating expenses decreased to
67.1% in 1997 from 69.1% in 1996. This decrease primarily was due to
improvements in labor and pharmaceutical costs as a percentage of revenues
partially offset by an increase in other facility expenses, consisting
primarily of rent and medical director fees. In December 1996, we implemented
our Best Demonstrated Practices Program which focuses primarily upon deriving
efficiencies in labor and supply costs.
 
  General and administrative expenses. General and administrative expenses
increased $17,749,000 to $50,099,000 in 1997 from $32,350,000 in 1996, and as a
percentage of net operating revenues, general and administrative expenses
increased to 6.6% for 1997 from 6.5% in 1996. The increase was due to
additional corporate labor resources added to further our growth via
acquisitions proportionately in excess of revenue growth.
 
  Provision for doubtful accounts. The provision for doubtful accounts
increased $4,788,000 to $20,525,000 in 1997 from $15,737,000 in 1996. As a
percentage of net operating revenues, the provision for doubtful accounts
decreased to 2.7% in 1997 from 3.2% in 1996, due to better management of the
collection process for patient secondary balances remaining after Medicare, as
the primary payor, had paid 80% of the claim.
 
  Depreciation and amortization. Depreciation and amortization increased
$22,158,000 to $54,603,000 in 1997 from $32,445,000 in 1996, and as a
percentage of net operating revenues, depreciation and amortization increased
to 7.2% in 1997 from 6.5% in 1996. This increase was attributable to increased
amortization due to acquisition activity and increased depreciation from new
center leaseholds and routine capital expenditures.
 
  Merger expenses. Merger expenses include investment banking, legal,
accounting and other fees and expenses. There were no merger expenses in 1997,
as compared to $2,808,000 in 1996. In 1996, merger expenses were incurred as a
result of the mergers by RTC which were completed during 1996 and were
accounted for under the pooling-of-interests method of accounting.
 
  Operating income. Operating income increased $54,276,000 to $124,780,000 in
1997 from $70,504,000 in 1996, and as a percentage of net operating revenues,
operating income increased to 16.4% in 1997 from 14.2% in 1996. This increase
in operating income as a percentage of net operating revenues reflected a
decrease in facility operating costs and the provision for doubtful accounts
offset by an increase in general and administrative expenses and depreciation
and amortization.
 
  Interest expense. Interest expense increased $14,797,000 to $28,214,000 in
1997 from $13,417,000 in 1996, and as a percentage of net operating revenues,
interest expense was 3.7% in 1997 and 2.7% in 1996. The increase in interest
expense primarily was due to an increase in borrowings made under our credit
facilities to fund acquisitions.
 
                                       46
<PAGE>
 
  Interest Income. Interest income decreased $683,000 to $3,175,000 in 1997
from $3,858,000 in 1996. This decrease was due to the timing of cash receipts
and additional borrowings and the use of those funds for acquisitions. As a
percentage of net operating revenues, interest income decreased to 0.4% from
0.8% in 1996.
 
  Provision for income taxes. Provision for income taxes increased $17,252,000
to $40,212,000 in 1997 from $22,960,000 in 1996, and the effective income tax
rate after minority interests increased to 42.2% in 1997 from 40.0% in 1996.
The overall increase in the effective tax rate primarily reflected non-
deductible goodwill associated with stock acquired, and to foreign net
operating losses, for which no benefit was recognized during 1997, from
businesses in Argentina.
 
  Minority interests. Minority interests increased $924,000 to $4,502,000 in
1997 from $3,578,000 in 1996, and as a percentage of net operating revenues,
minority interest decreased to 0.6% in 1997 from 0.7% in 1996. This decrease in
minority interest as a percentage of net operating revenues was a result of a
relative proportionate decrease in the formation of partnership affiliates and
subsidiaries as a percentage of total new acquisitions.
 
Liquidity and capital resources
 
 Sources and uses of cash
 
  Our primary capital requirements have been the funding of our growth through
acquisitions and de novo developments and equipment purchases. Net cash
provided by operating activities was $17.6 million for the year ended December
31, 1998 and net cash provided by operating activities was $26.7 million for
the year ended December 31, 1997. Net cash provided by operating activities
consists of our net income (loss), increased by non-cash expenses such as
depreciation, amortization, non-cash interest, the provision for doubtful
accounts, cumulative change in accounting principle, and extraordinary loss,
and adjusted by changes in components of working capital, primarily accounts
receivable, and accrued merger and related expenses in 1998. Accounts
receivable, before allowance for doubtful accounts, increased during 1998 by
$200.3 million, of which approximately $140.6 million was due to the increase
in our revenues; $23.7 million was due to a build up of accounts receivable
with governmental payors which occurs while these payors process a change of
ownership for facilities newly acquired by us, a process that typically can
take from three to twelve months; approximately $11.0 million was due to a
payment suspension imposed on our Florida-based laboratory by its Medicare
carrier; and approximately $9.2 million was due to the change in patient mix
toward commercial insurance from Medicare because of the changes in Medicare
secondary payor extension, resulting in a longer period for receiving
reimbursement because commercial insurance carriers generally process claims
less quickly than Medicare.The remaining $15.8 million was due to unresolved
collections on accounts primarily attributable to third party private payors.
Additionally, the allowance for doubtful accounts increased by $31.2 million,
including $11.5 million related to RTC receivables deemed uncollectible at year
end.
 
  Net cash used in investing activities was $475.1 million in 1998 and $526.2
million in 1997. Our principal uses of cash in investing activities have been
related to acquisitions, purchases of new equipment and leasehold improvements
for our facilities, as well as the development of new facilities. Net cash
provided by financing activities was $492.8 million for 1998 and $484.3 million
in 1997 primarily consisting of borrowings from our credit facilities and the
proceeds from our 7% convertible subordinated notes offering. As of December
31, 1998, we had working capital of $385.1 million, including cash of $41.5
million.
 
  We believe that we will have sufficient liquidity to fund our debt service
obligations and our growth strategy over the next 12 months.
 
 Expansion
 
  Our strategy is to continue to expand our operations both through the
development of de novo facilities and through acquisitions. The development of
a typical facility generally requires $1.0 million to $1.2 million for initial
construction and equipment and $0.2 million to $0.3 million for working
capital. Based on our
 
                                       47
<PAGE>
 
experience, a de novo facility typically achieves operating profitability,
before depreciation and amortization, by the 9th to 18th month of operation.
However, the period of time for a de novo facility to break even depends on
many factors which can vary significantly from facility to facility, and,
therefore, our past experience may not be indicative of the performance of
future developed facilities. In 1998, we developed 27 new facilities, three of
which we manage, and we expect to develop approximately 40 additional new
facilities in 1999. We anticipate that our aggregate capital requirements for
purchases of equipment and leasehold improvements for facilities, including de
novo facilities, will be approximately $75.0 to $100.0 million for 1999.
 
  During 1998, we paid cash of approximately $338.2 million for a pharmacy,
minority interests in certain of our partnerships and 76 facilities. The
operations of six of these facilities were not included in our consolidated
financial statements until January 1, 1999. Since December 31, 1998, we have
acquired 17 additional facilities for approximately $44.6 million.
 
 Credit facilities
 
  In April 1998, we replaced our $1.05 billion bank credit facilities with an
aggregate of $1.35 billion in two senior bank facilities. The credit facilities
consist of a seven-year $950.0 million revolving senior credit facility
maturing on March 31, 2005 and a ten-year $400.0 million senior term facility
maturing on March 31, 2008. As of December 31, 1998 the outstanding principal
amount outstanding under the revolving facility was $353.6 million and under
the term facility was $396.0 million. The term facility requires annual
principal payments of $4.0 million, with the $360.0 million balance due on
maturity. Therefore, we had $596.4 million available for borrowing under the
revolving facility.
 
  The credit facilities contain financial and operating covenants including,
among other things, requirements that we maintain certain financial ratios and
satisfy certain financial tests, and imposes limitations on our ability to make
capital expenditures, to incur other indebtedness and to pay dividends. As of
the date hereof, we are in compliance with all such covenants.
 
 Interest rate swaps
 
  During the quarter ended June 30, 1998, we entered into forward interest rate
cancelable swap agreements with a combined notional amount of $800.0 million.
The lengths of the agreements are between three and ten years with cancellation
clauses at the swap holder's option from one to seven years. The underlying
blended interest rate is fixed at approximately 5.65% plus an applicable margin
based upon our current leverage ratio. Currently, the effective interest rate
for these swaps is 6.90%.
 
 Subordinated notes
 
  The $125.0 million outstanding 5 5/8% convertible subordinated notes due 2006
issued by RTC bear interest at the rate of 5 5/8%, payable semi-annually and
require no principal payments until 2006. The 5 5/8% notes are convertible into
shares of our common stock at an effective conversion price of $25.62 per share
and are redeemable by us beginning in July 1999.
 
  In November we issued 7% convertible subordinated notes due 2009 in the
aggregate principal amount of $345.0 million. The 7% notes are convertible at
any time, in whole or in part, into shares of our common stock at a conversion
price of $32.81 and will be redeemable after November 16, 2001. We used the net
proceeds from the sale of the 7% notes to pay down debt under the revolving
facility, which may be reborrowed.
 
Year 2000 considerations
 
  Since the summer of 1998, all of our departments have been meeting with our
information systems department to determine the extent of our Y2K exposure.
Project teams have been assembled to work on correcting Y2K problems and to
perform contingency planning to reduce our total exposure. Our goal is to have
all corrective action and contingency plans in place by the third quarter of
1999.
 
                                       48
<PAGE>
 
  Software applications and hardware. Each component of our software
application portfolio, or SAP, must be examined with respect to its ability to
properly handle dates in the next millennium. As part of our software
assessment plan, key users will test each and every component of our SAP. These
tests will be constructed to make sure each component operates properly with
the system date advanced to the next millennium.
 
  The major phases of our software assessment plan are as follows:
 
  . Complete SAP inventory;
 
  . Implement Y2K compliant software as necessary;
 
  . Analyze which computers have Y2K problems and the cost to repair;
 
  . Test all vendors' representations; and
 
  . Fix any computer-specific problems.
 
  Our billing and accounts receivable software is known to have a significant
Y2K problem. We have already addressed this issue by obtaining a new, Y2K
compliant version of this software. We expect to complete conversion to this
Y2K compliant version by the end of the third quarter of 1999.
 
  Operating systems. We are also reviewing our operating systems to assess
possible Y2K exposure. We use several different network operating systems, or
NOS, for multi-user access to the software that resides on the respective
servers. Each NOS must be examined with respect to its ability to properly
handle dates in the next millennium. Key users will test each component of our
SAP with a compliant version of the NOS. One level beneath the NOS is a special
piece of software that comes into play when the computer is "booted" that
potentially has a Y2K problem and that is the basic input output system
software, or BIOS. The BIOS takes the date from the system clock and uses it in
passing the date to the NOS which in turn passes the date to the desktop
operating system. The system clock poses another problem in that some system
clocks were only capable of storing a two-digit year while other computer
clocks stored a four-digit year. This issue affects each and every computer we
have purchased. To remedy these problems, we plan to inventory all computer
hardware using a Y2K utility program to determine whether we have a BIOS or a
system clock problem. We then intend to perform a BIOS upgrade or perform a
processor upgrade to a Y2K compliant processor.
 
  Our financial exposure from all sources of SAP and operating system Y2K
issues known to date is approximately $300,000, none of which has been
expended.
 
  Dialysis centers, equipment and suppliers. The operations of our dialysis
centers can be affected by the Y2K problem so a contingency plan must be in
place to prevent the shutdown of these centers. Each center will be responsible
for completing a survey of the possible consequences of a failure of the
information systems of our vendors and formulating a contingency plan by the
third quarter of 1999. Divisional vice presidents will then review these plans
to assure compliance.
 
  All of our biomedical devices, including dialysis machines that have a
computer chip in them will be checked thoroughly for Y2K compliance. We have
contacted or will contact each of the vendors of the equipment we use and ask
them to provide us with documentation regarding Y2K compliance. Where it is
technically and financially feasible without jeopardizing any warranties, we
will test our equipment by advancing the clock to a date in the next
millennium.
 
  In general, we expect to have all of our biomedical devices Y2K compliant by
the third quarter of 1999. We have not yet been able to estimate the costs of
upgrading or replacing certain of our biomedical devices as we do not yet know
which of these machines, if any, are not currently Y2K compliant.
 
  In addition to factors noted above which are directly within our control,
factors beyond our direct control may disrupt our operations. If our suppliers
are not Y2K complaint, we may experience inventory shortages
 
                                       49
<PAGE>
 
and run short of critical supplies. If the utilities companies, transportation
carriers and telecommunications companies which service us experience Y2K
difficulties, our operations will also be adversely affected and some of our
facilities may need to be closed. We are in the process of taking steps to
reduce the impact on our operations in such instances and implementing
contingency plans to address any possible unavoidable affect which these
difficulties would have on our operations.
 
  To address the possibility of a physical plant failure, we are contacting the
landlords of each of our facilities to insure that they will provide access to
our staff and any other key service providers. We are also providing written
notification to our utilities companies of the locations, schedules and
emergency services required of each of our dialysis facilities. In case a
physical plant failure should result in an emergency closure of any of our
facilities, we are currently:
 
  . Confirming that backup hospital affiliation agreements are up-to-date and
    complete;
 
  . Reviewing appropriate elements of our disaster preparedness plan with our
   staff and patients;
 
  . Adopting/modifying emergency treatment orders and rationing plans with
    our medical directors to provide patient safety; and
 
  . Conducting patient meetings with social workers and dieticians.
 
  To minimize the affect of any Y2K non-compliance on the part of suppliers, we
are currently taking steps to:
 
  . Identify our critical suppliers and survey each of them to assess their
    Y2K compliance status;
 
  . Identify alternative supply sources where necessary;
 
  . Identify Y2K compliant transportation/shipping companies and establish
    agreements with them to cover situations where our current supplier's
    delivery systems go down;
 
  . Include language in contracts with new suppliers addressing Y2K
    performance obligations, requirements and failures;
 
  . Stock our dialysis facilities with one week of additional inventory; the
    orders will be placed two weeks before January 2000, to ensure receipt;
 
  . Require critical distributors to carry additional inventory earmarked for
    us; and
 
  . Prepare a critical supplier contact/pager list for Y2K emergency supply
    problems and ensure that contact persons will be on call 24 hours a day.
 
  General. The extent and magnitude of the Y2K problem as it will affect us,
both before, and for some period after, January 1, 2000, are difficult to
predict or quantify for a number of reasons. Among the most important are our
lack of control over systems that are used by the third parties who are
critical to our operations, such as telecommunications and utilities companies,
the complexity of testing interconnected networks and applications that depend
on third-party networks and the uncertainty surrounding how others will deal
with liability issues raised by Y2K-related failures. Moreover, the estimated
costs of implementing our plans for fixing Y2K problems do not take into
account the costs, if any, that might be incurred as a result of Y2K-related
failures that occur despite our implementation of these plans.
 
  With respect to third-party non-governmental payors, we are in the process of
determining where our exposure is and developing contingency plans to prevent
the interruption of cash flow. With respect to Medicare payments, neither HCFA
nor its financial intermediaries have any contingency plan in place. However,
HCFA has mandated that its financial intermediaries submit a draft of their
contingency plans to it by March 1999 and that they be prepared to ensure that
no interruption of Medicare payments results from Y2K-related failures of their
systems. With respect to MediCal, the largest of our third-party state payors,
we are already submitting our claims with a four-digit numerical year in
accordance with the current system. We are currently working with our other
state payors individually to determine the extent of their Y2K compliance.

  Although we currently are not aware of any material operational issues
associated with preparing our internal computer systems, facilities and
equipment for Y2K, we cannot assure you, due to the overall complexity of the
Y2K issues and the uncertainty surrounding third party responses to Y2K issues,
that we will not experience material unanticipated negative consequences and/or
material costs caused by undetected errors or defects in our or third party
systems or by our failure to adequately prepare for the results of such errors
or defects, including costs or related litigation, if any. The impact of such
consequences could have a material adverse effect on our business, financial
condition or results of operations.

Interest rate sensitivity
 
  The table below provides information about our derivative financial
instruments and other financial instruments that are sensitive to changes in
interest rates, including interest rate swaps and debt obligations. For debt
obligations, the table presents principal cash flows and related weighted
average interest rates by expected maturity dates. For interest rate swaps, the
table presents notional amounts and weighted average interest rates by
expected, contractual maturity dates. Notional amounts are used to calculate
the contractual payments to be exchanged under the contract. Weighted average
variable rates are based on implied forward rates in the yield curve at the
reporting date.

Exchange rate sensitivity
 
  We have foreign operations in Argentina, Germany, Italy and the United
Kingdom. Because the Argentine Peso trades evenly with the U.S. dollar and
because our operations in Germany, Italy and the United Kingdom are new and
relatively small, we have not experienced significant foreign exchange rate
risk. Through December 31, 1998, we have not utilized any derivative financial
instruments to manage foreign exchange rate risk.

1995. Based solely on our review of the copies of such forms received by us, or
written representations from certain reporting persons that no Form 5's were
required for those persons, we believe that our insiders complied with all
applicable Section 16(a) filing requirements during fiscal 1998.

(1) All options are nonqualified stock options and were granted under our 1997
    Equity Compensation Plan. The options vest over four year periods at an
    annual rate of 25% beginning on the first anniversary of the date of grant.
(2) The estimated grant date present value reflected in the above table was
    determined using the Black-Scholes model. The material assumptions and
    adjustments incorporated in the Black-Scholes model in estimating the value
    of the options reflected in the above table include the following: (a) the
    respective option exercise price for each individual grant, equal to the
    fair market value of the underlying stock on the date of grant; (b) the
    exercise of options within six years of the date that they become
    exerciseable;
 
                                       56

   (c) a risk-free interest rate of 5.632% per annum; (d) volatility of 34.2
   calculated using the daily prices of our common stock; and (e) a dividend
   yield of 0%. The ultimate values of the options will depend on the future
   market price of our common stock, which cannot be forecasted with
   reasonable accuracy. The actual value, if any, an optionee will realize
   upon exercise of an option will depend on the excess of the market value of
   our common stock over the exercise price on the date the option is
   exercised. We cannot assure that the value realized by an optionee will be
   at or near the value estimated by the Black-Scholes model or any other
   model applied to value the options.

(1) Value is determined by subtracting the exercise price from the fair market
    value of $28.3125 per share, the closing price for our common stock as
    reported by the New York Stock Exchange as of December 31, 1998, and
    multiplying the remainder by the number of underlying shares of common
    stock.
 
(2) In February 1999, Mr. Chaltiel voluntarily cancelled 1,166,667 of these
    options to increase the number of options available for grant under our
    existing stock option plans.
 
Employment agreements
 
  Mr. Chaltiel entered into an employment agreement with us on August 14,
1994, pursuant to which he was employed by us for an initial term of three
years, with one year automatic extensions at the end of each year. We may
terminate this agreement at any time, subject, among other things, to
severance payments as provided in the employment agreement. His base salary
paid during fiscal 1998 was $315,026 and is subject to annual review by our
board for possible increases, with a minimum increase tied to the California
consumer price index. Until May 31, 1999, Mr. Chaltiel will be entitled to a
yearly bonus of up to 150% of his base salary based upon our achieving certain
EBITDA performance targets. He also may be awarded an additional bonus at the
discretion of the Board if EBITDA targets are exceeded by more than 15%. After
May 31, 1999, Mr. Chaltiel will be awarded bonuses in a manner as determined
in the sole discretion of the Board, on a basis reasonably consistent with
past bonuses for similar performance.
 
  On March 2, 1998 we amended Mr. Chaltiel's employment agreement to ensure
that any additional compensation payable to Mr. Chaltiel upon a change in
control would not be reduced by certain tax obligations possibly imposed by
sections 280G or 4999 of the Internal Revenue Code of 1986.
 
  Mr. Chaltiel also was granted options pursuant to our 1994 Equity
Compensation Plan representing a total of approximately 1,477,778 shares of
common stock. The options had an exercise price of $0.90. By their terms, half
of the options were to vest over a four-year period and the other half were to
vest on the ninth anniversary of the date of grant, subject to accelerated
vesting in the event that we satisfied certain EBITDA performance targets. On
September 18, 1995, our board and our stockholders approved an agreement dated
as
 
                                      57
<PAGE>
 
of the same date by and between Mr. Chaltiel and us pursuant to which the
vesting schedule for these options was accelerated so that all of Mr.
Chaltiel's outstanding options became vested and exercisable immediately. In
connection with this agreement, Mr. Chaltiel agreed to exercise all of his
options at that time to purchase 1,477,778 shares of common stock at an
exercise price of $0.90 per share. Mr. Chaltiel paid the exercise price
pursuant to a $1,330,000 four-year promissory note bearing interest at the
lesser of the prime rate or 8%. This note was subject to repayment, in part or
in full, to the extent of the receipt of any proceeds received by Mr. Chaltiel
upon disposition of such shares of common stock, and Mr. Chaltiel pledged these
shares as collateral for repayment of this note. Also, in accordance with the
agreement, we agreed to advance Mr. Chaltiel funds of up to $1,521,520
principal amount in the aggregate relating to Mr. Chaltiel's tax liability in
connection with additional taxes associated with the exercise of such options.
Such loans were evidenced by two additional promissory notes executed by Mr.
Chaltiel. The first note for $1,348,447 was executed concurrently with Mr.
Chaltiel's exercise of his options. The second note for $173,073 was executed
as of April 15, 1996. Simultaneously with the execution of the agreement, we
entered into a Release and Pledge Agreement with Mr. Chaltiel whereby we
released 1,855,555 shares of common stock owned by Mr. Chaltiel from a previous
pledge agreement and substituted the newly acquired 1,477,778 shares of common
stock. On March 31, 1998, Mr. Chaltiel repaid his outstanding loan balances
with us and we released those shares held as collateral under the Release and
Pledge Agreement.
 
  On March 2, 1998 we entered into new employment agreements with each of our
executive officers, other than Mr. Chaltiel. These employment agreements
provide for an initial term through December 31, 1998 and will continue
thereafter with no further action by either party for successive one year
terms. Each executive officer's base salary will be subject to annual increases
consistent with the California consumer price index. Each executive officer
also will be entitled to receive a bonus of up to 75% of his base salary each
year. Fifty percent of this bonus will be based upon our achievement of certain
earnings per share targets and 50% will be granted at the discretion of the
compensation committee. In the event of a constructive discharge following a
change in control or a termination for any reason other than material cause,
each executive officer will be entitled to a lump sum payment equal to his
then-current base salary.
 
  Each of Messrs. Frie, Cosgrove, King and Lindenfeld also have been granted
options pursuant to our equity compensation plans. These options vest at a rate
of 25% per year over four years. The exercise price of the options ranges from
$0.90 per share to $32.1875 per share. Upon voluntary termination of
employment, we may have the right to acquire all shares of our common stock
held by the terminated employee at fair market value per share, as defined in
the employment agreement.
 
  On December 14, 1995, our board amended the stock option agreement of each
executive officer, other than Mr. Chaltiel, to provide for the immediate
vesting of all of such officers' stock options at any time following the sale
of 50% or more of our stock or assets, or upon a merger, consolidation or
reorganization in which we do not survive, if any of such officers' employment
is terminated for any reason.
 
Compensation of directors
 
  Directors who are our employees or officers do not receive compensation for
service on the board or any committee of the board. Each of our directors who
is not one of our officers or employees is entitled to receive $20,000 per year
and certain additional compensation for attending more than four board meetings
per year. Our directors also are reimbursed for their reasonable out-of-pocket
expenses in connection with their travel to and attendance at the meetings of
the board. In addition, each director who is not one of our officers or
employees is entitled to receive 25,000 options to purchase shares of our
common stock each year they are elected to serve on our board. These options
have an exercise price equal to the fair market value of our common stock on
the date of grant and generally vest over four year periods at an annual rate
of 25% beginning on the first anniversary of the date of grant.
 
                                       58

Compensation committee interlocks and insider participation
 
  None of our executive officers or directors serves as a member of the board
of directors or compensation committee of any other entity which has one or
more executive officers serving as a member of our board. During fiscal 1998,
Messrs. Chaltiel and Andersons and Dr. Massry were our officers, employees or
consultants. Messrs. Andersons and Grauer and Ms. Herzlinger each served as a
member of the compensation committee of our board of directors during fiscal
1998.
 
Item 12. Security Ownership of Certain Beneficial Owners and Management.
 
  The following table sets forth information regarding the ownership of our
common stock as of March 15, 1999 by (a) all those persons known by us to own
beneficially more than 5% of our common stock, (b) each of our directors and
each executive officers, and (c) all directors and executive officers as a
group. Except as otherwise noted under "Certain Relationships and Related
Transactions," we know of no agreements among our stockholders which relate to
voting or investment power over our common stock or any arrangement the
operation of which may at a subsequent date result in a change of control of
TRCH.

Item 13. Certain Relationships and Related Transactions.
 
  Victor M.G. Chaltiel is our Chairman of the Board, Chief Executive Officer,
President and one of our directors. Pursuant to Mr. Chaltiel's employment
agreement and the 1994 Equity Compensation Plan, Mr. Chaltiel purchased
1,855,557 shares of common stock at $0.90 per share during the year ended May
31, 1995. Mr. Chaltiel paid $835,000 of the purchase price in cash, with the
remainder being evidenced by a four-year promissory note bearing interest at
the lesser of the prime rate or 8% per annum, which note is secured by a pledge
of certain shares of our stock owned by Mr. Chaltiel. In July 1995, the board
approved a one-year deferral of all scheduled principal and accrued interest
payments under all outstanding promissory notes from our officers, including
this four-year promissory note. In September 1995, we entered into an agreement
with Mr. Chaltiel pursuant to which Mr. Chaltiel purchased 1,477,778 shares of
common stock upon exercise of options held by him. Mr. Chaltiel paid for such
shares with a four-year promissory note for $1,330,000 bearing interest at the
lesser of the prime rate or 8%. This note was subject to repayment, in part or
in full, to the extent of the receipt of proceeds received by Mr. Chaltiel upon
disposition of the shares of common stock, and Mr. Chaltiel pledged these
shares as collateral for repayment of this note. We also agreed to advance
Mr. Chaltiel funds of up to $1,521,520 principal amount in the aggregate
relating to Mr. Chaltiel's tax liability in connection with the shares. Such
loans were evidenced by two additional promissory notes executed by
Mr. Chaltiel. The first note for $1,348,447 was executed concurrently with Mr.
Chaltiel's exercise of his options in September 1995. The second note for
$173,073 was executed in April 1996. Simultaneously with the execution of the
agreement, we entered into a Release and Pledge Agreement with Mr. Chaltiel
whereby we released 1,855,557 shares of common stock owned by Mr. Chaltiel from
the previous pledge agreement and substituted the newly acquired 1,477,778
shares of common stock. On March 31, 1998, Mr. Chaltiel repaid his outstanding
loan balance with us and we released those shares held as collateral under the
related Release and Pledge Agreement.
 
  Certain of our officers and employees have received loans from us in
connection with the purchase of shares of our common stock. All of the loans
have similar terms. The loans bear interest at the lower of 8% or the prime
rate, and are secured by all of the borrower's interests in our common stock,
including all vested stock options. When made, the loans had a four-year term
and one quarter of the original principal amount thereof plus all accrued
interest thereon had to be paid annually, subject to the limitation that the
borrower was not required to make any payment that exceeded 50% of the after-
tax proceeds of such borrower's bonus from us, based on maximum tax rates then
in effect. To date, our board has approved deferrals of all scheduled principal
and accrued interest payments under all such loans. No other terms of the loans
have been changed.
 
  As of December 31, 1998, Leonard W. Frie, Barry C. Cosgrove and John E. King
had loans outstanding from us with principal amounts of $100,000, $70,000 and
$25,000, respectively. With respect to Mr. Cosgrove,
 
                                       60
<PAGE>
 
$50,000 was borrowed to purchase shares of common stock and $20,000 was
borrowed for relocation costs. Mr. Chaltiel had an outstanding loan of $835,000
prior to the addition in September 1995 of $2,678,447 pursuant to similar loans
in connection with Mr. Chaltiel's exercise of options for 1,477,778 shares of
common stock and related personal income tax obligations, as described above.
These loans were secured by a pledge of 1,444,445 shares of our common stock.
Mr. Chaltiel received a similar loan from us in April 1996, in the amount of
$173,073, in connection with additional taxes associated with the exercise of
those options. On March 31, 1998, Mr. Chaltiel repaid his outstanding loan
balances with us and we released those shares held as collateral.
 
  Maris Andersons, one of our directors, serves as a consultant to us. He has
been granted options, vesting over four years, to purchase an aggregate of
76,792 shares of our common stock in consideration for these services. As of
December 31, 1998, Mr. Andersons had exercised 41,666 of said options leaving a
balance of 35,126 options to purchase shares of our common stock.
 
  Shaul G. Massry, one of our directors, serves as a consultant to us. In
addition to certain compensation as a member of the board, Dr. Massry also
receives $120,000 per year and has been granted options, vesting over four
years, to purchase an aggregate of 44,722 shares of our common stock in
consideration for these services. As of December 31, 1998, Dr. Massry had
exercised 11,110 of such options leaving a balance of 33,612 options to
purchase shares of our common stock.
 
  We entered into a shareholders' agreement with DLJ Merchant Banking Partners,
L.P., or DLJMBP, certain members of management and NME Properties Corporation,
a wholly-owned subsidiary of Tenet, in August 1994 pursuant to which, among
other provisions, DLJMBP had the right to nominate four of the five members of
our board. Although this right has terminated, an affiliate of DLJMBP, Peter T.
Grauer, continues to serve on our board. The shareholders' agreement further
provides for certain registration rights and for restrictions on transfers of
our common stock, certain rights of first refusal in favor of DLJMBP in the
event NME proposes to transfer shares of our common stock and certain rights
and obligations of NME to participate in transfers of shares by DLJMBP. DLJ and
certain of its affiliates from time to time perform various investment banking
and other services for us, for which we pay customary consideration.
 
  We have entered into indemnity agreements with each of our directors and all
of our officers, which agreements require us, among other things, to indemnify
them against certain liabilities that may arise by reason of their status or
service as our directors, officers, employees or agents, other than liabilities
arising from conduct in bad faith or which is knowingly fraudulent or
deliberately dishonest, and, under certain circumstances, to advance their
expenses incurred as a result of proceedings brought against them.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
Total Renal Care Holdings, Inc.
 
  In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, of stockholders' equity, and of cash flows
present fairly, in all material respects, the financial position of Total Renal
Care Holdings, Inc. and its subsidiaries at December 31, 1997 and 1998, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1998 in conformity with generally accepted
accounting principles. 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 of these
statements in accordance with generally accepted auditing standards which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

1. Organization and summary of significant accounting policies
 
 Organization
 
  We operate kidney dialysis facilities and provide related medical services in
Medicare certified dialysis facilities in various geographic sectors of the
United States and also in Argentina, Puerto Rico, Europe and Guam.
 
  On February 27, 1998 we acquired Renal Treatment Centers, Inc., or RTC, with
headquarters in Berwyn, Pennsylvania in a merger. In connection with the
merger, we issued 34,565,729 shares of our common stock in exchange for all of
the outstanding shares of RTC common stock. RTC stockholders received 1.335
shares of our common stock for each share of RTC common stock that they owned.
We also issued 2,156,424 options in substitution for previously outstanding RTC
stock options, including 1,662,354 of the vested options that were exercised on
the merger date or shortly thereafter. In addition, we guaranteed $125,000,000
of RTC's 5 5/8% subordinated convertible notes. In conjunction with this
transaction, our board of directors and our stockholders authorized an
additional 140,000,000 shares of common stock.
 
  The RTC merger transaction was accounted for as a pooling of interests and as
such, these consolidated financial statements have been restated to include RTC
for all periods presented. There were no transactions between RTC and us prior
to the combination and no adjustments were necessary to conform RTC's
accounting policies to ours. Certain reclassifications also were made to the
RTC financial statements to conform to our presentations.
 
  The results of operations for Total Renal Care Holdings, Inc., or TRCH, and
the combined amounts presented in the consolidated financial statements follow:

  As a result of the merger, RTC's revolving credit agreement was terminated
and the outstanding balance of approximately $297,228,000 was paid off through
additional borrowings under our credit facilities. The remaining net
unamortized deferred financing costs in the amount of $4,392,000, less tax of
$1,580,000, related to RTC's revolving credit agreement were recognized as an
extraordinary loss during 1998.
 
  In connection with the merger, we developed a plan which included initiatives
to integrate our operations with those of RTC, eliminate duplicative overhead,
facilities and systems and improve service delivery. These integration
activities were commenced during the first quarter of 1998 and are expected to
be substantially completed by approximately July 1, 1999.

  Merger and related costs recorded during the first quarter of 1998 include
costs associated with certain of the integration activities, transaction costs
and costs of employee severance and amounts due under employment agreements and
other compensation programs. These amounts are more fully described below and
are based on our estimates of those costs.
 
  A summary of merger and related costs and accrual activity through December

  Direct transaction costs consist primarily of investment banking fees, legal
and accounting costs and other direct transaction costs, including the costs of
consultants, printing and registration, which were incurred by both TRCH and
RTC in connection with the merger. We concluded negotiations as to certain
amounts due in the fourth quarter of 1998 and subsequently we paid these
amounts.
 
  Severance and employment costs were incurred for the following:
 
  . Severance pay--The merger constituted a constructive termination of
    employment under various preexisting employment contracts with RTC
    officers. Terminated RTC officers were entitled to severance payments and
    tax gross-up payments of approximately $6,500,000. In addition,
    approximately 80 employees of RTC were informed that their positions
    would be eliminated. Most of these employees were formerly located in
    RTC's administrative office and a laboratory under development. The
    terminations were structured over the integration period, which continued
    through the end of 1998. The accrued severance payments to these
    employees amounted to approximately $1,600,000. The remaining balance of
    such severance costs of $600,000 was paid in the first quarter of 1999
    and tax gross up payments of approximately $3,000,000 are expected to be
    paid in the second quarter of 1999.
 
  . Option exercises--Pre-existing terms of RTC stock option grants permitted
    the exercise of options by tender of RTC shares. Some of the RTC shares
    tendered had been held less than six months by the option holders and, as
    required by Emerging Issues Task Force Issue 84-18, we recognized a
    noncash expense of approximately $16,000,000 equal to the difference
    between the exercise price of the options and the market value of the
    stock on the date of exercise. We also incurred approximately $600,000 of
    payroll tax related to the exercise of nonqualified stock options.
 
  . Bonuses--RTC and TRCH each awarded special bonuses as a result of the
    merger, paid in the first quarter of 1998, for which approximately
    $16,300,000 was included in merger and related costs.
 
  In connection with the RTC merger, we developed a plan which included
initiatives to integrate the operations of TRCH and RTC, eliminate duplicative
overhead, facilities and systems and improve service

delivery. These integration activities were commenced during the first quarter
of 1998 and are expected to be substantially completed by approximately July 1,
1999.
 
  We eliminated the following RTC departments: human resources, managed care,
laboratory, and all finance functions, with the exception of patient
accounting. The finance functions eliminated included payroll, financial
reporting and analysis, budgeting, general ledger, accounts payable, and tax
functions. The RTC human resources and managed care departments were
discontinued in Berwyn, Pennsylvania and consolidated with our respective
departments in our Torrance, California headquarters as of September 30, 1998.
All finance functions, with the exception of patient accounting, were
consolidated into our Tacoma, Washington business office as of December 31,
1998. RTC's laboratory, located in Las Vegas, Nevada, was closed prior to its
commencement of operation. All laboratory functions were consolidated into our
laboratories in Minnesota and Florida in February 1998.
 
  Costs to integrate operations include the following:
 
  . Laboratory restructuring--As part of our merger integration plan, we
    decided to restructure our laboratories. To optimize post-merger
    operations, we terminated a long-term management services agreement with
    a third party that provided full laboratory management on a contract
    basis. The termination fee of approximately $3,800,000 was negotiated in
    the first quarter of 1998. We also immediately halted development of
    RTC's new laboratory, which was not required for post-merger operations.
    The RTC laboratory, which was being developed in leased space, is now
    vacant and a new sublessee is being sought. As a result of this decision,
    previously capitalized leasehold improvements of $2,600,000 were
    expensed. Additionally, merger and related costs include approximately
    $1,000,000 of pre-opening start up costs incurred during the first
    quarter of 1998 relating to the terminated RTC laboratory and $1,500,000
    of remaining lease payments. The accrual for lease payments was not
    offset by any anticipated sublease income. No such income has been
    received to date and the remaining balance of this accrual at December
    31, 1998 was approximately $1,165,000.
 
  . Initial merger costs--Approximately $5,400,000 was expensed for
    integration activities which occurred at the time of the merger. Such
    costs include a special training program held in March 1998 and attended
    by many of our employees, including former RTC employees, merger related
    travel costs, consultant costs and other costs attributed to the merger.
 
  During the fourth quarter of 1998 we reduced the remaining balance of the
accrual by $1,247,000 representing differences between initial estimates and
actual amounts of expenses incurred.
 
  The accrued merger and related costs initially reported by us in the first
quarter of 1998 amounted to $92,835,000. As discussed in Note 17, we have
received comments from the Securities and Exchange Commission and have revised
our financial reporting relating to certain costs initially included in our
merger and related costs and accrual as follows:

 Basis of presentation
 
  Our consolidated financial statements include our accounts and those of our
wholly owned and majority-owned corporate subsidiaries and partnership
investments, including certain majority-owned and 50% owned partnerships where
we have control. All significant intercompany transactions and balances have
been eliminated in consolidation. The results of operations of our foreign-
based entities are included through November 30, 1998.
 
  At December 31, 1998 we, through our direct and indirect subsidiaries, were
the general partner in 24 partnerships which own and operate 59 dialysis
facilities. We consolidate our majority and 50% owned partnership investments
because we exercise control through direct ownership and/or the rights to
manage the daily operations of the business and the 50% or minority partners
have only protective rights on the partnership. Minority-owned partnership
investments are recorded under the equity method of accounting.
 
  In February 1996, RTC acquired, through two separate transactions,
Intercontinental Medical Services, Inc., or IMS, and Midwest Dialysis Unit and
its affiliates, or MDU. In July 1996, RTC acquired Panama City Artificial
Kidney Center, Inc. and North Florida Artificial Kidney Center, Inc., or the
Kidney Center Group. Accordingly, the consolidated financial statements have
been prepared to give retroactive effect to these mergers. Each of the
transactions was separately accounted for as a pooling-of-interests. The
consolidated financial statements include the results of IMS, MDU and the
Kidney Center Group as of January 1, 1996.
 
 Net operating revenues
 
  Revenues are recognized when services and related products are provided to
patients in need of ongoing life sustaining kidney dialysis treatments.
Operating revenues consist primarily of dialysis and ancillary fees from
patient treatments. These amounts are reported at the amounts expected to be
realized from governmental and third-party payors, patients and others for
services provided. Appropriate allowances are established based upon credit
risk of specific third-party payors, historical trends and other factors and
are reflected in the provision for doubtful accounts as a component of
operating expenses in the consolidated statements of income.
 
  During 1996, 1997 and 1998, we received approximately 64%, 61% and 56%
respectively, of our dialysis revenues from Medicare and Medicaid programs.
Accounts receivable from Medicare and Medicaid amounted to $205,564,000 and
$204,770,000 as of December 31, 1997 and 1998, respectively. Medicare
historically pays approximately 80% of government established rates for
services provided by us. The remaining 20% typically is paid by state Medicaid
programs, private insurance companies or directly by the patients receiving the
services.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
  Medicare and Medicaid programs funded by the U.S. government generally
reimburse us under prospective payment systems at amounts different from our
established private rates. Revenues under these programs are generally
recognized at prospective rates which are subject to periodic adjustment by
federal and state agencies. We bill non-governmental third-party payors at
established private rates. We have contracts for the provision of dialysis
services to members of certain managed care organizations which generally
include rate provisions at less than the established private rates.
 
  In August 1993, the Omnibus Budget Reconciliation Act of 1993, or OBRA 93,
became effective. The Healthcare Financing Administration, or HCFA, originally
interpreted certain provisions of OBRA 93 to require employer group health
sponsored insurance plans, or private payors, to be the primary payor for
patients who became dually entitled to Medicare benefits because they developed
ESRD after they had earlier been entitled to Medicare due to age or disability.
In July 1994, HCFA instructed the Medicare fiscal intermediaries to apply the
provisions of OBRA 93 retroactively to August 10, 1993. Accordingly, we billed
the responsible private payors as the primary payors and recognized these
revenues, at the generally higher private rates, as services were rendered for
periods after August 10, 1993.
 
  In April 1995, HCFA issued instructions of clarification to the fiscal
intermediaries which stated that it had misinterpreted the OBRA 93 provisions,
and that Medicare would continue as the primary payor despite a patient
obtaining dual eligibility status under the Medicare ESRD provisions.
Accordingly, we began recognizing revenues at Medicare rates for all such
patients going forward from April 1995. We also adjusted our financial
statements to reflect revenues earned at Medicare rates for such patients
during the period from August 1993 through April 1995. This resulted in a
reduction in revenues for the period August 1993 through April 1995 of
approximately $3.1 million as these revenues had been previously recognized at
the generally higher private rates.
 
  In June 1995, a federal court issued a preliminary injunction against HCFA
prohibiting HCFA from retroactively applying its reinterpretation of the OBRA
93 provisions to periods prior to its April 1995 instructions of clarification.
After the issuance of this preliminary injunction, we determined that a
permanent injunction would likely be issued, and we adjusted our financial
statements to reflect revenues earned during the period from August 1993
through April 1995 at the generally higher private rates. We made no adjustment
to revenues recognized going forward from April 1995 because the injunction did
not prohibit the prospective effect of HCFA's reinterpretation.
 
  In January 1998, a federal court issued a permanent injunction preventing
HCFA from applying its reinterpretation of the OBRA 93 provisions because that
application would be unlawful retroactive rulemaking. We did not adjust our
revenues in January 1998 in response to the permanent injunction because
revenues had already been recognized at the generally higher private rates
after the issuance of the preliminary injunction in June 1995.
 
  As a Medicare and Medicaid provider, we are subject to extensive regulation
by both the federal government and the states in which we conduct our business.
Due to heightened awareness of federal and state budgets, scrutiny is being
placed on the health care industry, potentially subjecting us to regulatory
investigation and changes in billing procedures (see Note 13).
 
  The provisions of the Kennedy-Kassebaum legislation issued January 1, 1997
may limit our ability to pay for policy premiums for patients even with proven
financial hardship. However, we believe that the bill did not intend to limit
our ability to pay premiums for insurance coverage to third-party or
governmental payors. In the fall of 1997, the Office of Inspector General of
the Department of Health and Human Services, of HHS, issued an advisory opinion
which would allow us to make grants to a foundation that may provide for these
premium payments on behalf of eligible ESRD patients. Furthermore, a recent
Congressional action will allow dialysis

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
providers to pay their patients' insurance premiums for secondary insurance.
These premiums are generally less than the 20% co-payment that a private
insurer would pay. Dialysis providers would be allowed to capture as
incremental profit the difference between the premiums paid to these secondary
insurers and the reimbursement amounts received from them. We plan to pay for a
patient's secondary insurance premium only if the patient does not qualify for
Medicaid and the patient demonstrates an inability to pay for this insurance.
Dialysis providers will be able to pay directly their patients' premiums for
secondary insurance beginning upon the enactment of regulations implementing
the Congressional action, which is expected in the third quarter of 1999.
 
  We provide management services to dialysis facilities that we do not own
under long-term and short-term agreements. Our fees typically are determined as
a percentage of the facilities' patient revenues or operating results. The net
fee due us is included in our net operating revenues as earned. Any costs
incurred in performing these management services are recognized in facility
operating and general and administrative expenses.
 
 Cash and cash equivalents
 
  Cash equivalents are highly liquid investments with original maturities of
three months or less.
 
  As part of our cash management strategy, we utilize a zero-balance
disbursement account that resulted in a cash overdraft of $10,392,000 as of
December 31, 1998. This overdraft has been reclassified and included in other
accrued liabilities in these financial statements.
 
 Inventories
 
  Inventories are stated at the lower of cost (first-in, first-out) or market
and consist principally of drugs and dialysis related supplies.
 
  Supplier rebates associated with medical supplies inventory are based on a
percentage of purchases during the contract period and generally are paid to us
on a quarterly or semi-annual basis. The percentage rate of rebate recognized
by us is based upon expected purchase thresholds to be achieved during the
contract period. We recognize supplier rebates in the same period that the
related inventory expense is recognized and they are included in facility
operating expenses in the consolidated statement of income. A corresponding
rebate receivable is included in other current assets in the consolidated
balance sheet.
 
 Property and equipment
 
  Property and equipment are stated at cost. Maintenance and repairs are
charged to expense as incurred. Depreciation and amortization expense are
computed using the straight-line method over the useful lives of the assets
estimated as follows: buildings, 20 to 40 years; leaseholds and improvements,
over the shorter of their estimated useful life or the lease term; and
equipment, 3 to 15 years.
 
 Capitalized interest
 
  We capitalize interest associated with the costs of significant facility
expansion and construction. Interest is capitalized by using an interest rate
which is equal to the weighted average borrowing rate on our long-term debt.
Approximately $685,000 and $804,000 in interest expense was capitalized during
1997 and 1998, respectively.
 
 Intangible assets
 
  Business acquisition costs allocated to patient lists are amortized generally
over five to eight years using the straight-line method. Business acquisition
costs allocated to covenants not to compete are amortized over the terms of the
agreements, typically three to eleven years, using the straight-line method.
Deferred debt issuance costs are amortized over the term of the debt using the
effective interest method. Pre-opening and development costs are expensed as
incurred during 1998.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 
  The excess of aggregate purchase price over the fair value of net assets of
businesses acquired is recorded as goodwill. Goodwill is amortized over 15 to
40 years using the straight-line method. Currently, the blended average life of
our goodwill is 34 years.
 
 Impairment of Property and Equipment and Intangible Assets
 
  The carrying value of property and equipment and intangible assets are
assessed for any permanent impairment by evaluating the operating performance
and future undiscounted cash flows from operations of the underlying
businesses. Adjustments are made if the sum of the expected future undiscounted
net cash flows is less than book value. Statement of Financial Accounting
Standards No. 121, Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed of, or SFAS 121, requires that long-lived
assets be reviewed for impairment whenever events or changes in circumstances
indicate that the carrying amount of assets may not be recoverable.
 
 Income taxes
 
  We account for income taxes using an asset and liability approach, which
requires recognition of deferred income taxes for all temporary differences
between the tax and financial reporting bases of our assets and liabilities
based on enacted tax rates applicable to the periods in which the differences
are expected to be recovered or settled.
 
 Minority interests
 
  Minority interests represent the proportionate equity interest of other
partners and stockholders in our consolidated entities which are not wholly
owned. As of December 31, 1998, these included 24 active partnerships and
corporations.
 
 Stock-based compensation
 
  Statement of Financial Accounting Standards No. 123, Accounting for Stock-
Based Compensation, or SFAS 123, requires us to elect to account for stock-
based compensation on a fair value based model or an intrinsic value based
model. We currently use the intrinsic value based model which is the accounting
principle prescribed by Accounting Principles Board No. 25, Accounting for
Stock Issued to Employees, or APB 25. Under this model, compensation cost is
the excess of the quoted market price of the stock at the date of grant or
other measurement date over the amount an employee must pay to acquire the
stock. The fair value based model prescribed by SFAS 123 requires us to value
stock-based compensation using an accepted valuation model. Compensation cost
is measured at the grant date based on the value of the award and would be
recognized over the service period which is usually the vesting period. SFAS
123 requires us to either reflect the results of the valuation in the
consolidated financial statements or alternatively continue to apply the
provisions of APB 25 and make appropriate disclosure of the impact of such
valuation in the accompanying notes to consolidated financial statements.
 
  We have elected to continue to apply the provisions of APB 25 to our employee
stock-based compensation plans and have included the required disclosure of the
pro forma impact on net income and earnings per share of the difference between
compensation expense using the intrinsic value method and the fair value method
(see Note 10).
 
  Options granted to non-employees subsequent to December 15, 1998 are recorded
at the fair value based upon the fair value criteria of SFAS 123.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 
 Earnings per share
 
  In February 1997, the Financial Accounting Standards Board issued the
Statement of Financial Accounting Standards No. 128, Earnings Per Share, or
SFAS 128. SFAS 128 establishes standards for computing and presenting earnings
per share. Basic earnings per share is calculated by dividing net income before
extraordinary item and net income by the weighted average number of shares of
common stock outstanding. Earnings per common share assuming dilution includes
the dilutive effects of stock options and warrants, using the treasury stock
method, in determining the weighted average number of shares of common stock
outstanding. Not currently used in the calculation is the effect of our
convertible debt. For 1997 and 1998, the effect of our convertible debt is
antidilutive and as such, is not to be included in the diluted EPS calculation.
Earnings per share for all periods presented have been restated following the
provisions of SFAS 128.
 
 Interest rate swap agreements
 
  We have entered into interest rate swap agreements (see Note 8) as a means of
managing our interest rate exposure. We have not entered these agreements for
trading or speculative purposes. These agreements have the effect of converting
our line of credit obligation from a variable rate to a fixed rate. Net amounts
paid or received are reflected as adjustments to interest expense. The
counterparties to these agreements are large international financial
institutions. These interest rate swap agreements subject us to financial risk
that will vary during the life of the agreements in relation to the prevailing
market interest rates. We are also exposed to credit loss in the event of non-
performance by these counterparties. However, we do not anticipate non-
performance by the other parties, and no material loss would be expected from
non-performance by the counterparties.
 
 Financial instruments
 
  Our financial instruments consist primarily of cash, accounts receivable,
notes receivable, accounts payable, employee compensation and benefits, and
other accrued liabilities. These balances, as presented in the financial
statements at December 31, 1997 and 1998, approximate their fair value.
Borrowings under our credit facilities, of which $749,575,000 was outstanding
as of December 31, 1998, reflect fair value as they are subject to fees and
rates competitively determined in the marketplace. The fair value of the
interest rate swap agreements is based on the present value of expected future
cash flows from the agreement and was in a net payable position of $31,300,000
at December 31, 1998. The fair value of our 7% convertible subordinated notes
was equal to the carrying book value because of the proximity in the time
between the issue date of these notes and December 31, 1998; the fair value of
the RTC 5 5/8% convertible subordinated notes was approximately $124,000,000 at
December 31, 1998.
 
 Foreign currency translation
 
  Our principal operations outside of the United States are in Argentina and
are relatively self-contained and integrated within Argentina. The currency in
Argentina, which is considered the functional currency, floats with the U.S.
dollar, therefore, there are no significant foreign currency translation
adjustments. Our operations in Europe were nominal through December 31, 1998.
 
 Comprehensive income
 
  In June 1997, the Financial Accounting Standards Board, or FASB, issued
Statement of Financial Accounting Standards No. 130, Reporting Comprehensive
Income, or SFAS 130, which was adopted by us in the first quarter of 1998. SFAS
130 establishes standards for reporting and displaying comprehensive income and
its components (revenues, expenses, gains and losses) in a full set of general-
purpose financial statements
 
                                      F-13
<PAGE>
 
                        TOTAL RENAL CARE HOLDINGS, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
or as additional line items within the current set of financial statements.
Comprehensive income as defined includes certain changes in stockholders'
equity during a period from non-income sources. Such items may include foreign
currency translation adjustments, unrealized gains/losses from investing and
hedging activities, and other transactions. SFAS 130 requires that all items
that are required to be recognized under accounting standards as components of
comprehensive income be reported in a financial statement that is displayed
with the same prominence as other financial statements. As we have no
components of other comprehensive income through December 1998, there were no
disclosure requirements involved in our adoption of SFAS 130. In the future, we
are likely to have other comprehensive income that SFAS 130 will require us to
disclose.
 
 Segment information
 
  In June 1997, the FASB issued Statement of Financial Accounting Standards No.
131, Disclosures about Segments of an Enterprise and Related Information, which
requires that we report financial and descriptive information about our
reportable operating segments. We have determined that we do not have any
separately reportable segments.
 
 Derivative instruments and hedging activities
 
  In June 1998, the FASB issued Statement of Financial Accounting Standards No.
133, Accounting for Derivative Instruments and Hedging Activities, or SFAS 133.
SFAS 133 is effective for all fiscal quarters of all fiscal years beginning
after June 15, 1999. Accordingly, for us, SFAS 133 will become effective
January 1, 2000. SFAS 133 requires that all derivative instruments be recorded
on the balance sheet at their fair value. Changes in the fair value of
derivatives are recorded each period in current earnings or other comprehensive
income, depending on whether a derivative is designated as part of a hedge
transaction and, if it is, the type of hedge transaction. For fair-value hedge
transactions in which we are hedging changes in an asset's, liability's, or
firm commitment's fair value, changes in the fair value of the derivative
instrument will generally be offset in the income statement by changes in the
hedged item's fair value. For cash-flow hedge transactions, in which we are
hedging the variability of cash flows related to a variable-rate asset,
liability, or a forecasted transaction, changes in the fair value of the
derivative instrument will be reported in other comprehensive income. The gains
and losses on the derivative instrument that are reported in other
comprehensive income will be reclassified as earnings in the periods in which
earnings are impacted by the variability of the cash flows of the hedged item.
The ineffective portion of all hedges will be recognized in current-period
earnings.
 
  We have not yet determined the impact that the adoption of SFAS 133 will have
on our earnings or statement of financial position.
 
 Use of estimates
 
  The preparation of financial statements in conformity with generally accepted
accounting principles requires us 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 the reported
amounts of revenues and expenses during the reporting period. Actual results
could differ from those estimates.
 
 Reclassifications
 
  Certain prior year balances have been reclassified to conform to the current
year presentation.

  In April 1998, Statement of Position No. 98-5, Reporting on the Costs of
Start-up Activities, or SOP 98-5, was issued. We adopted SOP 98-5 effective
January 1, 1998. SOP 98-5 requires that pre-opening and organization costs,
incurred in conjunction with facility pre-opening activities, which previously
had been treated as deferred costs and amortized over five years, should be
expensed as incurred. As a result of the adoption of SOP 98-5, all remaining
unamortized pre-opening, development and organizational costs existing prior to
January 1, 1998 of $11,196,000 were recognized, net of tax of $4,300,000, as
the cumulative effect of a change in accounting principle in 1998.

 Credit facilities
 
  At December 31, 1998 and 1997, we had outstanding borrowings under our
revolving credit facility of $353,575,000 and $353,000,000, respectively, and
at December 31, 1998, $396,000,000 was outstanding under our fixed term loan.
 
  On April 30, 1998, we replaced our existing $1,050,000,000 credit facilities
with an aggregate of $1,350,000,000 in two senior bank facilities. These credit
facilities consist of a seven-year $950,000,000 revolving senior credit
facility and a ten-year $400,000,000 senior term facility. Up to $75,000,000
may be utilized for foreign financing. In general, borrowings under the credit
facilities bear interest at one of two floating rates selected by us: (a) the
Alternate Base Rate (defined as the higher of The Bank of New York's prime rate
or the federal funds rate plus 0.5%); or (b) Adjusted LIBOR (defined as the 30-
, 60-, 90- or 180-day London Interbank Offered Rate, adjusted for statutory
reserves) plus a margin that ranges from 0.45% to 1.75% depending on our
leverage ratio. As a result of this financing, remaining net deferred financing
costs in the amount of approximately $16,019,000, less tax of $6,087,000, were
recognized as an extraordinary loss in 1998.
 
  Maximum borrowings under the $950,000,000 revolving credit facility will be
reduced by $89,100,000 on September 30, 2001, $148,400,000 on September 30,
2002, and another $237,500,000 on September 30, 2003, and the revolving credit
facility terminates on March 31, 2005. Under the $400,000,000 term facility,
payments of $4,000,000 shall be made each consecutive year beginning on
September 30, 1998 and continuing through September 30, 2007. The remaining
balance of $360,000,000 is due on March 31, 2008 when the term facility
terminates. The credit facilities contain financial and operating covenants
including, among other things, requirements that we maintain certain financial
ratios and satisfy certain financial tests, and impose limitations on our
ability to make capital expenditures, to incur other indebtedness and to pay
dividends. We are in compliance with all such covenants.
 
  Certain of our subsidiaries, including Total Renal Care, Inc., or TRC, TRC
West, Inc., Total Renal Care Acquisition Corp., RTC, Renal Treatment Centers-
Mid Atlantic, Inc., Renal Treatment Centers-Northeast, Inc., Renal Treatment
Centers-California, Inc., Renal Treatment Centers-West, Inc. and Renal
Treatment Centers-Southeast, Inc., have guaranteed our obligations under the
credit facilities on a senior basis.
 
  RTC also had a credit agreement which provided for a $350,000,000 revolving
credit/term facility available to fund acquisitions and general working capital
requirements, of which $237,000,000 was outstanding as of December 31, 1997.
The RTC credit agreement was terminated and repaid with borrowings under our
credit facilities on February 27, 1998 in connection with the completion of our
merger with RTC. The remaining net amortized deferred financing costs in the
amount of $4,392,000 related to the RTC credit agreement were recognized as an
extraordinary loss, net of tax effect of $1,580,000, in 1998.
 
 5 5/8% convertible subordinated notes
 
  In June 1996, RTC issued $125,000,000 of 5 5/8% convertible subordinated
notes due 2006. These notes are convertible, at the option of the holder, at
any time after August 12, 1996 through maturity, unless previously redeemed or
repurchased, into our common stock at a conversion price of $25.62 principal
amount per share, subject to certain adjustments. At any time on or after July
17, 1999, all or any part of these notes will be redeemable at our option on at
least 15 and not more than 60 days' notice as a whole or, from time to time, in
part at redemption prices ranging from 103.94% to 100% of the principal amount
thereof, depending on the year of redemption, together with accrued interest
to, but excluding, the date fixed for redemption. These notes are guaranteed by
TRCH.

 7% convertible subordinated notes
 
  In November 1998, we issued $345,000,000 of 7% convertible subordinated notes
due 2009, or the 7% notes, in a private placement offering. The 7% notes are
convertible, at the option of the holder, at any time into common stock at a
conversion price of $32.81 principal amount per share. We may redeem the
7% notes on or after November 15, 2001. The 7% notes are general, unsecured
obligations junior to all of our existing and future senior debt and,
effectively all existing and future liabilities of ours and our subsidiaries.
We subsequently filed a registration statement covering the resale of the 7%
notes which has not yet been declared effective by the Securities and Exchange
Commission (see Note 17).

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 
 Acquisition obligations
 
  In 1994, pursuant to a business acquisition, RTC entered into an agreement to
pay $7,364,100 in annual installments commencing June 1995 through June 1998.
Interest on the unpaid principal amount of the note accrued at an annual rate
of 6.5%, payable in arrears each June 1 from 1995 from 1998. The note allowed
the seller to convert the principal amount of the note into that number of
shares of common stock of RTC based upon the average daily closing sale price
of RTC stock during December 1994. During 1997, the note payable was paid in
full through the issuance of common stock.
 
  In 1996, pursuant to a business acquisition, RTC entered into an agreement to
pay a total of $8,050,000 to the seller in a single installment in January
1997. During 1997, pursuant to several business acquisitions, RTC entered into
several other agreements to pay the various sellers a total of $24,468,000 in
single installments in January 1998.
 
  In conjunction with certain facility acquisitions, we have issued three
letters of credit. Two of these were released on April 1, 1997. The remaining
letter of credit of $3,000,000 is being released to the seller in three annual
principal installments of $1,000,000 commencing January 1997. We have also
agreed to pay the seller interest at 6.50% on the outstanding principal. As of
December 31, 1997 and December 31, 1998 the aggregate amount outstanding,
including accrued interest, was $2,183,000 and $1,106,000 respectively.
 
  In December 1998, we purchased two facilities for a combined total of
$15,223,000 with a short term loan made to the sellers, which subsequently has
been repaid. Because of its short term maturity it has been included in other
accrued liabilities as of December 31, 1998.
 
 Interest rate swap agreements
 
  On November 25, 1996, we entered into a seven-year interest rate swap
agreement involving the exchange of fixed and floating interest payment
obligations without the exchange of the underlying principal amounts. At
December 31, 1997, the total notional principal amount of this interest rate
swap agreement was $100,000,000 and the effective interest rate thereon was
7.57%. On July 24, 1997, we entered into a ten-year interest rate swap
agreement. At December 31, 1997, the total notional principal amount of this
interest rate swap agreement was $200,000,000 and the effective interest rate
thereon was 7.77%. In April 1998, in conjunction with the refinancing of our
senior credit facilities, these two forward interest rate swap agreements were
cancelled. The loss associated with the early cancellation of those swaps was
approximately $9,823,000.
 
  In May 1998, we entered into forward interest rate cancelable swap
agreements, with a combined notional amount of $800,000,000. The lengths of the
agreements are between three and ten years with cancellation clauses at the
swap holders' option from one to seven years. The underlying blended rate is
fixed at approximately 5.65% plus an applicable margin based upon our current
leverage ratio. At December 31, 1998, the effective interest rate for
borrowings under the swap agreement is 6.90%.
 
9. Leases
 
  We lease the majority of our facilities under noncancelable operating leases
expiring in various years through 2021. Most lease agreements cover periods
from five to ten years and contain renewal options of five to ten years at the
fair rental value at the time of renewal or at rates subject to consumer price
index increases since the inception of the lease. In the normal course of
business, operating leases are generally renewed or replaced by other similar
leases.

  The net book value of fixed assets under capital lease was $5,649,000 and
$4,314,000 at December 31, 1997 and 1998, respectively. Capital lease
obligations are included in long-term debt (see Note 8).
 
10. Stockholders' equity
 
 Public offerings of common stock
 
  On April 3, 1996, and October 31, 1996 we completed equity offerings of
13,416,667 and 4,166,667 shares of our common stock, respectively; 5,833,333
and 833,334, respectively, of which were sold for our account and 7,583,333 and
3,333,333 respectively, of which were sold by certain of our stockholders. The
net proceeds received by us of $109,968,000 and $18,350,000, respectively, were
used to repay borrowings incurred under our credit facilities in connection
with acquisitions, to repurchase and subsequently retire our 12% senior
subordinated notes, to finance other acquisitions and de novo developments and
for working capital and other corporate purposes.
 
 Change in shares, stock splits and dividends
 
  Dividend distributions paid during 1996 were to the former shareholders of
entities acquired by RTC in transactions accounted for as poolings of interests
as described in Note 1.
 
  On September 30, 1997 we announced a common stock dividend to all
stockholders of record as of October 7, 1997, to be paid on October 20, 1997.
Each stockholder received two additional shares of common stock for each three
shares held. Fractional shares calculated as a result of the stock dividend
were paid out in cash in the amount of approximately $14,000. As such, all
share and per share amounts presented in the financial statements and related
notes thereto have been retroactively restated to reflect this dividend which
was accounted for as a stock split.

 Stock-based compensation plans
 
  At December 31, 1998, we had four stock-based compensation plans, which are
described below.
 
  1994 plan. In August 1994, we established the Total Renal Care Holdings, Inc.
1994 Equity Compensation Plan which provides for awards of nonqualified stock
options to purchase our common stock and other rights to purchase shares of our
common stock to certain of our employees, directors, consultants and facility
medical directors.
 
  Under terms of the 1994 plan, we may grant awards for up to 8,474,078 shares
of our common stock. Original options granted generally vest on the ninth
anniversary of the date of grant, subject to accelerated vesting in the event
that we meet certain performance criteria. In April 1996, we changed the
vesting schedule for new options granted so that options vest over four years
from the date of grant. The exercise price of each option equals the market
price of our stock on the date of grant, and an option's maximum term is ten
years.
 
  Purchase rights to acquire 1,314,450 common shares for $0.90-$3.60 per share
have been awarded to certain employees under the 1994 plan. All of these rights
were exercised and we received notes for the uncollected portion of the
purchase proceeds. These notes bear interest at the lesser of The Bank of
New York's prime rate or 8%, are full recourse to the employees, and are
secured by the employees' stock. The notes are repayable four years from the
date of issuance, subject to certain prepayment requirements. At December 31,
1997 and 1998 the outstanding notes plus accrued interest totaled $212,000 and
$215,000, respectively.

  During fiscal 1995, 1,477,778 of the options issued to purchase our common
stock were issued to Victor M.G. Chaltiel. These options originally vested 50%
over four years and 50% in the same manner as other options granted under the
1994 plan. In September 1995, our board of directors and stockholders agreed to
accelerate Mr. Chaltiel's vesting period and all of the options became 100%
vested. Pursuant to this action, Mr. Chaltiel exercised all of the stock
options through the issuance of a full recourse note of $1,330,000 bearing
interest at the lesser of prime or 8%. Additionally, Mr. Chaltiel executed a
full recourse note for $1,349,000 bearing interest at the lesser of prime or 8%
per annum to meet his tax liability in connection with the stock option
exercise. In April 1996, this note was increased by an additional $173,000.
These notes were secured by other shares of company stock and matured in
September 1999 or upon disposition of the common stock by Mr. Chaltiel. During
1998, this note was repaid in full.
 
  1995 plan. In November 1995, we established the Total Renal Care Holdings,
Inc. 1995 Equity Compensation Plan which provides awards of stock options and
the issuance of our common shares, subject to certain restrictions, to certain
employees, directors and other individuals providing services to us. There are
1,666,667 common shares reserved for issuance under the 1995 plan. Options
granted generally vest over four years from the date of grant and an option's
maximum term is ten years, subject to certain restrictions. We generally issue
awards with the exercise prices equal to the market price of our stock on the
date of grant.
 
  1997 plan. In July 1997, we established the Total Renal Care Holdings, Inc.
1997 Equity Compensation Plan which provides awards of stock options and the
issuance of our common shares, subject to certain restrictions, to certain
employees, directors and other individuals providing services to us. In
February 1998, we increased the shares reserved for issuance under the 1997
plan to 7,166,667 common shares. Options granted generally vest over four years
from the date of grant and an option's maximum term is ten years. We generally
issue awards with the exercise prices equal to the market price of our stock on
the date of grant.
 
  The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following assumptions used for
grants for 1996, 1997, and 1998, respectively: dividend yield of 0% for all
periods; weighted average expected volatility of 36.35%, 35.12% and 33.98%;
risk-free interest rates of 6.56%, 6.40% and 5.51% and expected lives of six
years for all periods.
 
  A combined summary of the status of the 1994 plan, the 1995 plan, and the
1997 plan as of and for the years ended December 31, 1996, 1997 and 1998 is

  RTC plans. In September 1990, RTC established a stock plan, which provided
for awards of incentive and nonqualified stock options to certain directors,
officers, employees and other individuals. In 1995 and 1996, the stock plan was
amended to increase the number of RTC common shares available for grant to
3,253,395 and 4,321,395 respectively. In addition, in 1996, RTC established an
option plan for outside directors pursuant to which nonqualified stock options
to purchase up to 80,100 shares of RTC common stock were reserved for issuance.
 
  Options granted under RTC's plans generally vest from three to five years and
an option's maximum term is ten years, subject to certain restrictions.
Incentive stock options were granted at an exercise price not less than the
fair market value of RTC's common stock on the date of grant. Nonqualified
stock options were permitted to be granted as low as 50% of market value,
subject to certain floor restrictions. Accordingly, compensation expense for
the difference between the fair market value and the exercise price for
nonqualified stock options is recorded over the vesting period of these
options.
 
  In May 1995, RTC granted 559,557 incentive stock options to certain
directors, officers and employees of RTC. These options were granted at an
exercise price equal to the fair market value of RTC's common stock on the date
of the grant. These options vest over three years. Certain options totaling
407,175 vest upon the earlier of attainment of predetermined earnings per share
targets or nine years.
 
  In March 1996, RTC granted 821,495 incentive stock options to certain
directors, officers and employees of RTC. These options were granted at an
exercise price equal to the fair market value of RTC's common stock on the date
of the grant and vest over four years. Certain options aggregating 231,398 vest
upon the earlier of attainment of predetermined earnings per share targets or
nine years.
 
  In December 1996, RTC granted 133,500 incentive stock options to one of its
officers. These options were granted at an exercise price equal to the fair
market value of RTC's common stock on the date of the grant and were fully
vested on the grant date.
 
  Also in December 1996, RTC granted 40,050 non-qualified stock options in
connection with the release of RTC from certain obligations. The options were
granted at an exercise price equal to the fair market value of RTC's common
stock on the date of grant and were fully vested as of December 31, 1997.

  During 1997, RTC granted 1,182,543 incentive stock options to certain
directors, officers and employees. These options were granted at an exercise
price equal to the fair market value of RTC's common stock on the dates of the
grants and vest in two to five years.
 
  In 1997 RTC granted 26,700 options to acquisition consultants for covenants
not to compete. These options were granted at a price equal to the fair market
values of RTC's common stock on the date of the grant and were valued at
$235,000.
 
  Upon consummation of our merger with RTC, all outstanding options were
converted to Total Renal Care Holdings Inc. Special Purpose Option Plan
options. This plan provides for awards of incentive and nonqualified stock
options in exchange for outstanding RTC stock plan options. Options under this
plan have the same provisions and terms provided for in the RTC stock plan,
including acceleration provisions upon certain sale of assets, mergers and
consolidations. On the merger date, there was a conversion of 2,156,426 of
RTC's options. Further, options for 1,305,738 shares became fully vested due to
change in control accelerated vesting provisions which were contained in the
original grants. Options for 1,662,356 shares were exercised subsequent to the
merger date. Our Stock Plan Committee has the option of accelerating the
remaining options upon certain sales of assets, mergers and consolidations.
 
  The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following assumptions used for
1996 and 1997, respectively: dividend yield of 0% for all periods; weighted
average expected volatility of 29.3% and 43%; risk free interest rates of 6.18%
and 6.55%; and expected lives of 5.63 and 4.29 years.

  Stock Purchase Plan. In November 1995, we established the Total Renal Care
Holdings, Inc. Employees Stock Purchase Plan which entitles qualifying
employees to purchase up to $25,000 of common stock during each calendar year.
The amounts used to purchase stock are typically accumulated through payroll
withholdings and through an optional lump sum payment made in advance of the
first day of the plan. The plan allows employees to purchase stock for the
lesser of 100% of the fair market value on the first day of the purchase right
period or 85% of the fair market value on the last day of the purchase right
period. Each purchase right period begins on January 1 or July 1, as selected
by the employee and ends on December 31. Payroll withholdings related to the
plan, included in accrued employee compensation and benefits, were $1,120,000
and $1,892,000 at December 31, 1997, and 1998 respectively. Subsequent to
December 31, 1996, and December 31, 1997, 174,775 and 49,060 shares,
respectively were issued to satisfy our obligations under the plan.
 
  For the November 1995 and July 1996 purchase right periods the fair value of
the employees' purchase rights were estimated on the beginning date of the
purchase right period using the Black-Scholes model with the following
assumptions for grants on November 3, 1995, July 1, 1996, January 1, 1997 and
July 1, 1997, respectively: dividend yield of 0% for all periods; expected
volatility of 36.6% in 1995 and 1996 and 34.23% in 1997; risk-free interest
rate of 5.5%, 6.6%, 6.8% and 6.8% and expected lives of 1.2, 0.5, 1.0, and 0.5
years. Using these assumptions, the weighted-average fair value of purchase
rights granted were $2.86, $7.37, $15.31, and $11.17, respectively.
 
  The fair value of the January 1, 1998 and July 1, 1998 purchase right periods
were not estimated at December 31, 1998 because of the employees' ability to
withdraw from participation through December 31.

  Pro forma net income and earnings per share. We applied APB Opinion No. 25
and related interpretations in accounting for all of our plans. Accordingly, no
compensation cost has been recognized for our fixed stock option plans and our
stock purchase plan. Had compensation cost for our stock-based compensation
plans been determined consistent with SFAS 123, our net income and earnings per
share would have been reduced to the pro forma amounts indicated below:

11. Transactions with related parties
 
 Tenet
 
  Tenet Healthcare Corporation, or Tenet, owns less than 5% of our common stock
and we provide dialysis services to Tenet hospital patients under agreements
with terms of one to three years. The contract terms are comparable to
contracts with unrelated third parties. Included in the receivable from Tenet
are amounts related to these services of $534,000 and $350,000 at December 31,
1997 and 1998, respectively. Net operating revenues received from Tenet for
these services were $2,260,000, $2,640,000 and $2,424,000 for 1996, 1997 and
1998, respectively.
 
 DLJ
 
  A managing director of Donaldson, Lufkin & Jenrette, or DLJ, serves on our
board of directors and, prior to August 1997, an affiliate of DLJ held an
ownership interest in us. During 1996 DLJ was one of several underwriters for
two public stock offerings in which we issued 11,666,667 and 833,334 shares,
respectively. Fees for these transactions to DLJ or its affiliates were
$5,075,000, and $780,000, respectively. Effective with the August 1997 public
offering of common stock, DLJ and its affiliates no longer own an interest in
us. During 1998, DLJ advised us on our acquisition of RTC and assisted us in
the issuance of the 7% notes.

12. Employee benefit plan
 
  We have a savings plan for substantially all employees, which has been
established pursuant to the provisions of Section 401(k) of the Internal
Revenue Code, or IRC. The plan provides for employees to contribute from 1% to
15% of their base annual salaries on a tax-deferred basis not to exceed IRC
limitations. We may make a contribution under the plan each fiscal year as
determined by our board of directors. We made matched contributions of $58,000,
in accordance with specific state requirements, in 1998.
 
  RTC had a defined contribution savings plan covering substantially all of its
employees. RTC's contributions under the plan were approximately $548,000, and
$1,069,000 and $641,000 for years ended December 31, 1996, 1997 and 1998,
respectively. Effective July 1, 1998, the plan was terminated and merged into
our plan.
 
13. Contingencies
 
  Our Florida-based laboratory subsidiary is presently the subject of a
Medicare carrier review. The carrier has requested certain medical and billing
records for certain patients and we have provided the requested records. The
carrier has suspended further payments to the laboratory subsidiary, amounting
to approximately $11 million at December 31, 1998, and made a formal
overpayment determination. We are appealing the overpayment determination and
have filed a suit to lift the payment suspension.
 
  Following the announcement on February 18, 1999 of our preliminary results of
the fourth quarter of fiscal 1998 and the full year then ended, several class
action lawsuits were filed against us and certain of our officers in the U.S.
District Court for the Central District of California. The complaints are
similar and allege violations of federal securities laws arising from alleged
false and misleading statements primarily regarding our accounting for the
integration of RTC into TRCH and request unspecified monetary damages. We
believe that all of the claims are without merit and we intend to defend
ourselves vigorously. We anticipate that the attorneys' fees and related costs
of defending these lawsuits should be covered primarily by our directors and
officers insurance policies and we believe that any additional costs will not
have a material impact on our financial condition, results of operations or
cash flows.
 
  In addition, we are subject to claims and suits in the ordinary course of
business for which we believe we will be covered by insurance. We do not
believe that the ultimate resolution of these additional pending proceedings,
whether the underlying claims are covered by insurance or not, will have a
material adverse effect on our financial condition, results of operations or
cash flows.
 
14. Mergers and acquisitions
 
 Mergers
 
  During the fiscal year 1996, RTC completed the following three mergers:
 
  . The Kidney Center Group
 
  On July 23, 1996, RTC acquired the Kidney Center Group. The two dialysis
facilities acquired are located in Florida and serviced a total of
approximately 185 patients as of the acquisition date. The transaction was
accounted for under the pooling-of-interests method of accounting. In the
transaction, RTC issued 482,377 shares of its common stock in exchange for all
of the outstanding stock of the Kidney Center Group.
 
  . MDU
 
  On February 29, 1996, RTC acquired MDU. The 11 dialysis facilities acquired
are located in Oklahoma and serviced a total of approximately 317 patients as
of the acquisition date. The transaction was accounted for

under the pooling-of-interests method of accounting. In the transaction, RTC
issued 767,168 shares of its common stock in exchange for all of the
outstanding stock of MDU.
 
  . IMS
 
  On February 20, 1996, RTC acquired IMS. The four dialysis facilities acquired
are located in Hawaii and serviced a total of approximately 444 patients as of
the acquisition date. The transaction was accounted for under the pooling-of-
interests method of accounting. In the transaction, RTC issued 1,047,464 shares
of its common stock in exchange for all of the outstanding stock of IMS.
 
  The consolidated financial statements give retroactive effect to the mergers
with the Kidney Center Group, IMS and MDU and include the Kidney Center Group,
IMS and MDU for all periods presented. The following is a summary of the
separate and combined results of operations for 1996:

 Acquisitions
 
  We have implemented an acquisition strategy which, through December 31, 1998,
has resulted in the acquisition of (a) 396 facilities providing services to
ESRD patients; (b) two laboratories; (c) a pharmacy; (d) a vascular access
management company; and (e) a clinical research company specializing in renal
and renal-related services. The following is a summary of acquisitions that
were accounted for as purchases for 1996, 1997 and 1998.

17. Subsequent events
 
  During 1999, we received a comment letter from the SEC related to the
registration statement for our $345 million 7% convertible subordinated notes.
We responded to the initial comment letter and recently received a second
comment letter from the SEC which requires further analysis and response by us.
Based on the results of this process to date, we have made adjustments to our
accrual for merger and related charges as described in Note 1 and Note 16. The
SEC comment process is not complete and its resolution could require further
revisions to our financial statements.

                    SECOND AMENDMENT TO EMPLOYMENT AGREEMENT
 
  This Second Amendment (this "Amendment") to Employment Agreement is made
effective as of March 2, 1998 by and between Total Renal Care Holdings, Inc.
(the "Company"), a Delaware corporation, and Victor M.G. Chaltiel (the
"Executive").
 
                               W I T N E S E T H:
 
  WHEREAS, the Company and the Executive are parties to that certain Employment
Agreement dated as of August 11, 1994, as amended on that same date (the
"Agreement"); and
 
  WHEREAS, the Company and the Executive desire by this Amendment to clarify
and amend certain provisions of the Agreement all as more fully hereinafter set
forth.
 
  NOW, THEREFORE, in consideration of the mutual covenants and agreements
hereinafter set forth and for other good and valuable consideration, the
receipt of which the parties hereby acknowledge, the parties hereto, intending
to be legally bound hereby, agree as follows:
 
  1. Amendment.
 
  (a) The Company and the Executive agree that the definition of "Change of
Control" in Section 1 of the Agreement is hereby amended and restated as
follows:
 
    "Change of Control" shall mean (1) any transaction or series of
  transactions in which any person or group (within the meaning of Rule 13d-5
  under the Exchange Act and Sections 13(d) and 14(d) under the Exchange Act)
  becomes the direct or indirect "beneficial owner" (as defined under Rule
  13d-3 under the Exchange Act), by way of a stock issuance, tender offer,
  merger, consolidation, other business combination or otherwise, of greater
  than 50% of the total voting power (on a fully diluted basis as if all
  convertible securities had been converted and all warrants and options had
  been exercised) entitled to vote in the election of directors of the
  Company (including any transaction in which the Company becomes a wholly
  owned or majority owned subsidiary of another corporation), (ii) any merger
  or consolidation or reorganization in which the Company does not survive,
  (iii) any merger or consolidation in which the Company survives, but the
  shares of the Company's Common Stock outstanding immediately prior to such
  merger or consolidation represent 50% or less of the voting power of the
  Company after such merger or consolidation, and (iv) any transaction in
  which more than 50% of the Company's assets are sold.
 
  (b) The Company and the Executive agree that Section 5 of the Agreement is
hereby amended and restated as follows:
 
    5. Excess Parachute Payment. In the event that any payment or benefit
  received or to be received by Executive in connection with a Change of
  Control, whether payable pursuant to the terms of this Agreement or any
  other plan, arrangement or agreement by the Company, any predecessor or
  successor to the Company or any corporation affiliated with the Company or
  which becomes so affiliated pursuant to the transactions resulting in a
  Change of Control, both within the meaning of Section 1504 of the Internal
  Revenue Code of 1986, as amended (the "Code") (collectively all such
  payments are hereinafter referred to as the "Total Payments") is deemed to
  be an "Excess Parachute Payment" (in whole or in part) to Executive as a
  result of Section 280G and/or 4999 of the Code, as in effect at such time,
  no change shall be made to the Total Payments to be made in connection with
  the Change of Control, except that, in addition to all other amounts to be
  paid to Executive by the Company hereunder, the Company shall, within
  thirty (30) days of the date on which any Excess Parachute Payment is made,
  pay to Executive, in addition to any other payment, coverage or benefit due
  and owing hereunder, an amount determined by
<PAGE>
 
  (i) multiplying the rate of excise tax then imposed by Code Section 4999 by
  the amount of the "Excess Parachute Payment" received by Executive
  (determined without regard to any payments made to Executive pursuant to
  this Section 5) and (ii) dividing the product so obtained by the amount
  obtained by subtracting (A) the aggregate local, state and Federal income
  tax rates (including the value of the loss of itemized deductions under
  Section 68 of the Internal Revenue Code) applicable to the receipt by
  Executive of the "Excess Parachute Payment" (taking into account the
  deductibility for Federal income tax purposes of the payment of state and
  local income taxes thereon) from (B) the amount obtained by subtracting
  from 1.00 the rate of excise tax then imposed by Section 4999 of the Code.
  It is the Company's intention that Executive's net after-tax position be
  identical to that which would have obtained had Sections 280G and 4999 not
  been part of the Code. For purposes of implementing this Section 5, (i) no
  portion, if any, of the Total Payments, the receipt or enjoyment of which
  Executive shall have effectively waived in writing prior to the date of
  payment of the Total Payments, shall be taken into account, and (ii) the
  value of any non-cash benefit or any deferred cash payment included in the
  Total Payments shall be determined by the Company's independent auditors in
  accordance with the principles of Sections 280G(d)(3) and (4) of the Code.
 
  2. Ratification and Confirmation. All other terms and conditions of the
Agreement are hereby ratified and confirmed and shall continue in full force
and effect.
 
  3. Miscellaneous. This Amendment may be executed in two or more counterparts,
and by different parties on different counterparts, each of which shall be
deemed an original and in making proof of this Amendment it shall be necessary
only to produce sufficient counterparts. This Amendment and the rights and
obligations of the parties hereunder shall be construed in accordance with and
shall be governed by the laws of the State of California, conflict of laws
provisions notwithstanding.
 
  IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of the
day and year first above written.

                       AMENDMENT NO. 1 AND CONSENT NO. 1
                                       TO
                AMENDED AND RESTATED REVOLVING CREDIT AGREEMENT
 
  AMENDMENT NO. 1 AND CONSENT NO. 1 (this "Amendment"), dated as of August 5,
1998, to the Amended and Restated Revolving Credit Agreement (the "Revolving
Credit Agreement"), dated as of April 30, 1998, by and among TOTAL RENAL CARE
HOLDINGS, INC., a Delaware corporation (the "Borrower"), the lenders party
thereto (the "Lenders"), DLJ CAPITAL FUNDING, INC., as Syndication Agent (the
"Syndication Agent"), FIRST UNION NATIONAL BANK, as Documentation Agent, and
THE BANK OF NEW YORK, as administrative agent (in such capacity, the
"Administrative Agent").
 
                                    RECITALS
 
  I. Capitalized terms used herein which are not otherwise defined herein shall
have the respective meanings ascribed thereto in the Revolving Credit
Agreement.
 
  II. The Borrower has requested that the Administrative Agent and the Lenders
agree to amend the Revolving Credit Agreement upon the terms and conditions
contained herein, and the Administrative Agent and the Required Lenders are
willing to so agree.
 
  Accordingly, in consideration of the Recitals and the covenants and
conditions hereinafter set forth, and for other good and valuable
consideration, the receipt and adequacy of which are hereby acknowledged, the
parties hereto hereby agree as follows:
 
  1. Section 4.19 of the Revolving Credit Agreement is amended and restated in
its entirety to read as follows:
 
  The facilities operated by the Borrower and its Subsidiaries (the
  "Facilities") are qualified for participation in the Medicare and Medicaid
  programs (together with their respective intermediaries or carriers, the
  "Government Reimbursement Programs") and are entitled to reimbursement
  under the Medicare program for services rendered to qualified Medicare
  beneficiaries, and comply in all material respects with the conditions of
  participation in all Government Reimbursement Programs. There is no pending
  or, to Borrower's knowledge, threatened proceeding or investigation by any
  of the Government Reimbursement Programs with respect to (i) the Borrower's
  or any of its Subsidiaries' qualification or right to participate in any
  Government Reimbursement Program, (ii) the compliance or non-compliance by
  the Borrower or any of its Subsidiaries with the terms or provisions of any
  Government Reimbursement Program, or (iii) the right of the Borrower or any
  of its Subsidiaries to receive or retain amounts received or due or to
  become due from any Government Reimbursement Program, which proceeding or
  investigation, together with all other such proceedings and investigations,
  could reasonably be expected to have a Material Adverse Effect.
 
  2. Section 9.1(p) of the Revolving Credit Agreement is amended and restated
in its entirety to read as follows:
 
    (p) The Borrower or any Subsidiary, in each case to the extent it is
  engaged in the business of providing services for which Medicare or
  Medicaid reimbursement is sought, shall for any reason, including, without
  limitation, as the result of any finding, designation or decertification,
  lose its right or authorization, or otherwise fail to be eligible, to
  participate in Medicaid or Medicare programs or to accept assignments or
  rights to reimbursements under Medicaid regulations or Medicare
  regulations, or the Borrower or any Subsidiary has, for any reason, had its
  right to receive reimbursements under Medicaid or Medicare regulations
  suspended, and such loss, failure or suspension (together with all such
  other losses, failures and suspensions continuing at such time) shall have
  resulted in a Material Adverse Effect.
<PAGE>
 
  3. The Administrative Agent and the Lenders, to the extent their consent is
required, hereby consent to the amendment of the Term Loan Facility in a manner
substantially similar to this Amendment (the "First Term Loan Amendment").
 
  4. Paragraphs 1 through 3 of this Amendment shall become and shall be deemed
effective as of April 30, 1998 upon the prior or simultaneous satisfaction of
the following condition:
 
    (a) The First Term Loan Amendment shall have become effective, and the
  Administrative Agent shall have received a copy of the executed First Term
  Loan Amendment.
 
  5. On the date hereof, each Credit Party hereby (a) reaffirms and admits the
validity and enforceability of the Loan Documents (as amended by this
Amendment) and all of its obligations thereunder, (b) agrees and admits that it
has no defenses to or offsets against any such obligation, and (c) represents
and warrants that, after giving effect to the effectiveness of this Amendment,
no Default or Event of Default has occurred and is continuing, and that each of
the representations and warranties made by it in the Loan Documents (as amended
by this Amendment) to which it is a party is true and correct with the same
effect as though such representation and warranty had been made on the date
hereof.
 
  6. In all other respects, the Loan Documents shall remain in full force and
effect, and no amendment in respect of any term or condition of any Loan
Document contained herein shall be deemed to be an amendment in respect of any
other term or condition contained in any Loan Document.
 
  7. This Amendment may be executed in any number of counterparts all of which,
taken together, shall constitute one Amendment. In making proof of this
Amendment, it shall only be necessary to produce the counterpart executed and
delivered by the party to be charged.
 
  8. THIS AMENDMENT IS BEING EXECUTED AND DELIVERED IN, AND IS INTENDED TO BE
PERFORMED IN, THE STATE OF NEW YORK AND SHALL BE CONSTRUED AND ENFORCEABLE IN
ACCORDANCE WITH, AND BE GOVERNED BY, THE INTERNAL LAWS OF THE STATE OF NEW
YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS.

                AMENDED AND RESTATED REVOLVING CREDIT AGREEMENT
 
  AMENDMENT NO. 2 (this "Amendment"), dated as of November 12, 1998, to the
Amended and Restated Revolving Credit Agreement, as amended by Amendment No. 1
and Consent No. 1, dated as of August 5, 1998 (the "Revolving Credit
Agreement"), dated as of April 30, 1998, by and among TOTAL RENAL CARE
HOLDINGS, INC., a Delaware corporation (the "Borrower"), the lenders party
thereto (the "Lenders"), DLJ CAPITAL FUNDING, INC., as Syndication Agent (the
"Syndication Agent"), FIRST UNION NATIONAL BANK, as Documentation Agent, and
THE BANK OF NEW YORK, as administrative agent (in such capacity, the
"Administrative Agent").
 
                                    RECITALS
 
  I. Capitalized terms used herein which are not otherwise defined herein shall
have the respective meanings ascribed thereto in the Revolving Credit
Agreement.
 
  II. The Borrower has requested that the Administrative Agent and the Lenders
agree to amend the Revolving Credit Agreement upon the terms and conditions
contained herein, and the Administrative Agent and the Required Lenders are
willing to so agree.
 
  Accordingly, in consideration of the Recitals and the covenants and
conditions hereinafter set forth, and for other good and valuable
consideration, the receipt and adequacy of which are hereby acknowledged, the
parties hereto hereby agree as follows:
 
  1. Section 2.6(d) of the Revolving Credit Agreement is amended to replace the
amount "$200,000,000" with the following:
 
  the sum of $200,000,000 plus the face principal amount of Subordinated
  Indebtedness issued by the Borrower in November, 1998 (such sum not to
  exceed $500,000,000 in the aggregate).
 
  2. Section 4.19 of the Revolving Credit Agreement is amended and restated in
its entirety to read as follows:
 
  The facilities operated by the Borrower and its Subsidiaries (the
  "Facilities") are qualified for participation in the Medicare and Medicaid
  programs (together with their respective intermediaries or carriers, the
  "Government Reimbursement Programs") and are entitled to reimbursement
  under the Medicare program for services rendered to qualified Medicare
  beneficiaries, and comply in all material respects with the conditions of
  participation in all Government Reimbursement Programs. There is no pending
  or, to Borrower's knowledge, threatened proceeding or investigation by any
  of the Government Reimbursement Programs with respect to (i) the Borrower's
  or any of its Subsidiaries' qualification or right to participate in any
  Government Reimbursement Program, (ii) the compliance or non-compliance by
  the Borrower or any of its Subsidiaries with the terms or provisions of any
  Government Reimbursement Program, or (iii) the right of the Borrower or any
  of its Subsidiaries to receive or retain amounts received or due or to
  become due from any Government Reimbursement Program, which proceeding or
  investigation, together with all other such proceedings and investigations,
  could reasonably be expected to (x) have a Material Adverse Effect or (y)
  result in Consolidated net operating revenues for any (including any
  future) four fiscal quarter period of the Borrower constituting less than
  95% of Consolidated net operating revenues for the immediately preceding
  four fiscal quarter period of the Borrower.
 
                                       i
<PAGE>
 
  3. Section 8.9 of the Revolving Credit Agreement is amended to add a new
subsection (e) at the end thereof as follows:
 
    (e) The Borrower will not voluntarily prepay, redeem or repurchase any
  Subordinated Indebtedness, except that if such Subordinated Indebtedness is
  convertible into common stock of the Borrower, the Borrower may exercise
  any right it may have to redeem at any time after November 1, 2001 all or
  any part of such Subordinated Indebtedness if on the Determination Date the
  Applicable Premium is at least 1.05. For purposes of this subsection
  8.9(e):
 
    "Determination Date" shall mean, as applicable, either (i) the date on
  which such Subordinated Indebtedness is redeemed if no prior notice of
  redemption must be given or (ii) if the Borrower is required under the
  terms of such Subordinated Indebtedness to give prior irrevocable notice of
  redemption, the date (which date shall not be more than 45 days prior to
  the redemption date) on which such notice is given;
 
    "Applicable Premium" shall mean the fraction (i) the numerator of which
  is the "Average Market Value" and (ii) the denominator of which is the then
  applicable conversion price under the terms of such Subordinated
  Indebtedness; and
 
    "Average Market Value" shall mean the average of the last sale price of
  the Borrower's common stock as reported on the New York Stock Exchange (or
  if not listed for trading thereon, then on the principal national
  securities exchange or the principal automated quotation system on which
  such common stock is listed or admitted to trading) for the period of 10
  trading days ended two trading days prior to the date of redemption or the
  date on which notice of redemption is given, whichever is applicable with
  respect to such Subordinated Indebtedness.
 
  4. Section 9.1(p) of the Revolving Credit Agreement is amended and restated
in its entirety to read as follows:
 
    (p) The Borrower or any Subsidiary, in each case to the extent it is
  engaged in the business of providing services for which Medicare or
  Medicaid reimbursement is sought, shall for any reason, including, without
  limitation, as the result of any finding, designation or decertification,
  lose its right or authorization, or otherwise fail to be eligible, to
  participate in Medicaid or Medicare programs or to accept assignments or
  rights to reimbursements under Medicaid regulations or Medicare
  regulations, or the Borrower or any Subsidiary has, for any reason, had its
  right to receive reimbursements under Medicaid or Medicare regulations
  suspended, and such loss, failure or suspension (together with all such
  other losses, failures and suspensions continuing at such time) shall have
  resulted in (x) a Material Adverse Effect or (y) Consolidated net operating
  revenues for the immediately preceding four fiscal quarter period of the
  Borrower constituting less than 95% of Consolidated net operating revenues
  for any preceding four fiscal quarter period of the Borrower.
 
  5. This Amendment shall become and shall be deemed effective as of the date
hereof upon the prior or simultaneous satisfaction of the following conditions:
 
    (a) Receipt by each Lender that shall have executed and delivered this
  Amendment (without any reservation or condition) to the Administrative
  Agent before 3:00 p.m. (New York City time) on November 12, 1998 of a non-
  refundable fee in an amount equal to 0.25% of the Revolving Credit
  Commitment of such Lender.
 
  6. On the date hereof, each Credit Party hereby (a) reaffirms and admits the
validity and enforceability of the Loan Documents (as amended by this
Amendment) and all of its obligations thereunder, (b) agrees and admits that it
has no defenses to or offsets against any such obligation, and (c) represents
and warrants that, after giving effect to the effectiveness of this Amendment,
no Default or Event of Default has occurred and is continuing, and that each of
the representations and warranties made by it in the Loan Documents (as amended
by this Amendment) to which it is a party is true and correct with the same
effect as though such representation and warranty had been made on the date
hereof.
 
                                       ii

  7. In all other respects, the Loan Documents shall remain in full force and
effect, and no amendment in respect of any term or condition of any Loan
Document contained herein shall be deemed to be an amendment in respect of any
other term or condition contained in any Loan Document.
 
  8. This Amendment may be executed in any number of counterparts all of which,
taken together, shall constitute one Amendment. In making proof of this
Amendment, it shall only be necessary to produce the counterpart executed and
delivered by the party to be charged.
 
  9. THIS AMENDMENT IS BEING EXECUTED AND DELIVERED IN, AND IS INTENDED TO BE
PERFORMED IN, THE STATE OF NEW YORK AND SHALL BE CONSTRUED AND ENFORCEABLE IN
ACCORDANCE WITH, AND BE GOVERNED BY, THE INTERNAL LAWS OF THE STATE OF NEW
YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS.

                          SUBSIDIARY PLEDGE AGREEMENT
 
  This SUBSIDIARY PLEDGE AGREEMENT (as it may be amended, supplemented or
otherwise modified from time to time, this "Agreement") is dated as of February
27, 1998 and entered into by and between RENAL TREATMENT CENTERS, INC. a

AGENT (as hereinafter defined), the ACKNOWLEDGING INTEREST RATE EXCHANGERS (as
hereinafter defined) and the ACKNOWLEDGING CURRENCY EXCHANGERS (as hereinafter

  A. Pledgor is the legal and beneficial owner of the shares of Stock described
in Schedule I annexed hereto and issued by the corporations named therein.

24, 1997, with the financial institutions parties thereto (the "Revolving
Lenders"), DLJ Capital Funding Inc., as Syndication Agent, First Union National
Bank, as Documentation Agent, and The Bank of New York, as administrative agent
(the "Revolving Agent") (said Revolving Credit Agreement, as amended and as it
may hereafter be amended, supplemented or otherwise modified from time to time,
being the "Revolving Credit Agreement"), pursuant to which the Revolving
Lenders have made certain commitments, subject to the terms and conditions set
forth in the Revolving Credit Agreement, to extend certain credit facilities to
Borrower.
 
  C. Borrower has entered into that certain Term Loan Agreement dated as of
October 24, 1997, with the financial institutions parties thereto (the "Term
Lenders"), DLJ Capital Funding Inc., as Syndication Agent, and The Bank of New
York, as administrative agent (the "Term Agent") (said Term Loan Agreement, as
amended and as it may hereafter be amended, supplemented or otherwise modified
from time to time, being the "Term Loan Agreement"), pursuant to which Term
Lenders have extended or will extend credit, subject to the terms and
conditions set forth in the Term Loan Agreement, to Borrower.
 
  D. It is contemplated that the Borrower may from time to time enter into one
or more Interest Rate Agreements with one or more Revolving Lenders or Term
Lenders or their respective Affiliates (collectively, the "Interest Rate
Exchangers") and it is desired that the obligations of the Borrower under such
Interest Rate Agreements, including the obligation to make payments in the
event of early termination thereunder, be secured by the collateral described
herein; provided that any Interest Rate Exchanger desiring the benefit of such
security shall deliver to the Collateral Agent an acknowledgement to the
Intercreditor Agreement executed by such Interest Rate Exchanger and the
Borrower, pursuant to which such Interest Rate Exchanger agrees to be bound by
the terms thereof. Each Interest Rate Exchanger that has executed and delivered
to the Collateral Agent an acknowledgement to the Intercreditor Agreement is
referred to herein as an "Acknowledging Interest Rate Exchanger", and each
Interest Rate Agreement with an Acknowledging Interest Rate Exchanger is
referred to herein as a "Secured Interest Rate Agreement".
 
  E. It is contemplated that the Borrower may from time to time enter into one
or more Currency Agreements with one or more Revolving Lenders or Term Lenders
or their respective Affiliates (collectively, the "Currency Exchangers") and it
is desired that the obligations of the Borrower under such Currency Agreements,
including the obligation to make payments in the event of early termination
thereunder be secured by the collateral described herein; provided that any
Currency Exchanger desiring the benefit of such security shall deliver to the

to herein as an "Acknowledging Currency Exchanger" and each Currency Agreement
with an Acknowledging Currency Exchanger is referred to herein as a "Secured
Currency Agreement".

be advanced to Pledgor and thus the Secured Obligations (as hereinafter
defined) are being incurred for and will inure to the benefit of Pledgor (which
benefits are hereby acknowledged).
 
  G. Collateral Agent has been appointed as collateral agent hereunder pursuant
to the Intercreditor Agreement by the Revolving Agent on behalf of the
Revolving Lenders, the Term Agent on behalf of the Term Lenders, and each
Interest Rate Exchanger and Currency Exchanger signing an acknowledgement to
the Intercreditor Agreement.
 
  H. Borrower has covenanted and agreed under the Revolving Loan Agreement and
the Term Loan Agreement to cause Pledgor to grant the security interests and
undertake the obligations contemplated by this Agreement.
 
  NOW, THEREFORE, in consideration of the premises and in order to induce the
Revolving Lenders to make and continue their respective loans to, and issue
Letters of Credit (as hereinafter defined) for the account of, the Borrower,
and to induce the Term Lenders to make and continue their respective loans to

Secured Parties, a security interest in, all of Pledgor's right, title and
interest in and to the following, in each case whether now owned or existing or
hereafter arising or acquired, whether tangible or intangible and wherever
located (the "Pledged Collateral"):
 
    (a) all shares of Stock of any Person that is on the date hereof or
  hereafter becomes a First-Tier wholly-owned Subsidiary of Pledgor or a
  First-Tier Domestic Subsidiary of Pledgor that is a Guarantor (whether or
  not wholly-owned by Pledgor) (such shares being the "Pledged Shares"), all
  securities convertible into and warrants, options and other rights to
  purchase or otherwise acquire, any Pledged Shares, the certificates or
  other instruments representing such Pledged Shares, securities, warrants,
  options or other rights and any interest of Pledgor in the entries on the
  books of any financial intermediary pertaining to such shares, and all
  dividends, cash, warrants, rights, instruments and other property or
  proceeds from time to time received, receivable or otherwise distributed in
  respect of or in exchange for any or all of such Pledged Shares,
  securities, warrants, options or other rights; provided that Pledgor shall
  not be required to pledge more than the Maximum Percentage (as hereinafter
  defined) of the shares of Stock of any Foreign Subsidiary;
 
    (b) all additional shares of, and all securities convertible into and
  warrants, options and other rights to purchase or otherwise acquire, Stock
  of any issuer of the Pledged Shares from time to time acquired by Pledgor
  in any manner (which shares shall be deemed to be part of the Pledged
  Shares), the certificates or other instruments representing such additional
  shares, securities, warrants, options or other rights and any interest of
  Pledgor in the entries on the books of any financial intermediary
  pertaining to such additional shares, and all dividends, cash, warrants,
  rights, instruments and other property or proceeds from time to time
  received, receivable or otherwise distributed in respect of or in exchange
  for any or all of such additional shares, securities, warrants, options or
  other rights;
 
    (c) to the extent not covered by clauses (a) through (b) above, all
  proceeds of any or all of the foregoing Pledged Collateral. For purposes of
  this Agreement, the term "proceeds" has the meaning assigned to it under
  Article 9 of the New York Uniform Commercial Code and to the extent not
  otherwise included, shall include whatever is receivable or received when
  Pledged Collateral or proceeds are sold, exchanged, collected or otherwise
  disposed of, whether such disposition is voluntary or involuntary, and
  includes, without limitation, proceeds of any indemnity or guaranty payable
  to Pledgor or Collateral Agent from time to time with respect to any of the
  Pledged Collateral.
 
  SECTION 3. Security for Obligations. This Agreement secures, and the Pledged
Collateral is collateral security for, the prompt payment or performance in
full when due, whether at stated maturity, by required prepayment, declaration,
acceleration, demand or otherwise (including the payment of amounts that would
become due but for the operation of the automatic stay under Section 362(a) of
the Bankruptcy Code, 11 U.S.C. (S)362(a)), of all obligations and liabilities
of every nature of Borrower now or hereafter existing under or arising out of
or in connection with the Financing Documents, whether for principal, interest
(including without limitation interest that, but for the filing of a petition
in bankruptcy with respect to Borrower, would accrue on such obligations),
reimbursement of amounts drawn under Letters of Credit, fees,
<PAGE>
 
expenses, indemnities or otherwise, whether voluntary or involuntary, direct or
indirect, absolute or contingent, liquidated or unliquidated, whether or not
jointly owed with others, and whether or not from time to time decreased or
extinguished and later increased, created or incurred, and all or any portion
of such obligations or liabilities that are paid, to the extent all or any part
of such payment is avoided or recovered directly or indirectly from Collateral
Agent or any Secured Party as a preference, fraudulent transfer or otherwise
(all such obligations and liabilities being the "Underlying Debt"), and all
obligations of every nature of Pledgor now or hereafter existing under this
Agreement (all such obligations of Pledgor, together with the Underlying Debt,
being the "Secured Obligations").
 
  SECTION 4. Delivery of Pledged Collateral. All certificates or instruments
representing or evidencing the Pledged Collateral shall be delivered to and
held by or on behalf of Collateral Agent pursuant hereto and shall be in
suitable form for transfer by delivery or, as applicable, shall be accompanied
by Pledgor's endorsement, where necessary, or duly executed instruments of
transfer or assignment in blank, all in form and substance satisfactory to
Collateral Agent. Collateral Agent shall have the right, at any time in its
discretion and without notice to Pledgor, to transfer to or to register in the
name of Collateral Agent or any of its nominees any or all of the Pledged
Collateral, subject only to the revocable rights specified in Section 8(a). In
addition, Collateral Agent shall have the right at any time to exchange
certificates or instruments representing or evidencing Pledged Collateral for
certificates or instruments of smaller or larger denominations.
 
  Collateral Agent acknowledges that, notwithstanding Pledgor's representation
and warranty in Section 5(b) hereof, Pledgor may deliver to Collateral Agent
stock certificates, together with undated stock powers, representing less than
100% (but no less than 66%) of the outstanding shares of stock of the Foreign
Subsidiaries; all outstanding shares of the Foreign Subsidiaries being referred
to herein as the "Foreign Shares". Because the intent of Pledgor and Collateral
Agent is to grant a security interest in a percentage of the Foreign Shares
equal to 66% or such other percentage as is the maximum percentage of the
Foreign Shares that can be pledged to the Collateral Agent without constituting
an investment of earnings in U.S. property under Section 956 (or any successor
provision) of the Code that would trigger an increase in the gross income of
Pledgor pursuant to Section 951 (or any successor provision) of the Code (such
percentage being the "Maximum Percentage"), Collateral Agent hereby confirms
that the Pledged Shares of the Foreign Subsidiaries shall refer only to, and
the grants of security interests created hereby shall extend only to, the
Maximum Percentage of the Foreign Shares.
 
  If Collateral Agent shall take any action to foreclose on the Foreign Shares,
Collateral Agent hereby agrees to act only with regard to the Maximum
Percentage of the Foreign Shares; provided, however, that nothing herein shall
preclude Collateral Agent from exercising the stock powers with respect to all
outstanding Foreign Shares to take such action as may be necessary to transfer
the Foreign Shares (the "Remaining Shares") to Pledgor or to such other person
or entity as Pledgor designates. The parties hereto agree that Collateral Agent
has no fiduciary or other responsibilities or duties with regard to the
Remaining Shares and that Collateral Agent is serving only as custodian with
respect to the Remaining Shares.
 
  SECTION 5. Representations and Warranties. Pledgor represents and warrants as
follows:
 
    (a) Due Authorization, etc. of Pledged Collateral. All of the Pledged
  Shares have been duly authorized and validly issued and are fully paid and
  non-assessable.
 
    (b) Description of Pledged Collateral. The Pledged Shares (other than the
  Foreign Shares) constitute 100% of the issued and outstanding shares of
  Stock of each issuer thereof, and there are no outstanding warrants,
  options or other rights to purchase, or other agreements outstanding with
  respect to, or property that is now or hereafter convertible into, or that
  requires the issuance or sale of, any Pledged Shares. The Pledged Shares of
  each Foreign Subsidiary represent the Maximum Percentage of the issued and
  outstanding shares of Stock of such Foreign Subsidiary.
 
    (c) Ownership of Pledged Collateral. Pledgor is the legal, record and
  beneficial owner of the Pledged Collateral free and clear of any Lien
  except for the security interest created by this Agreement
<PAGE>
 
  and as otherwise permitted under the Revolving Credit Agreement or the Term
  Loan Agreement, as the case may be.
 
    (d) Governmental Authorizations. Except as may be disclosed on Schedule
  5(d) with respect to Pledged Shares of a Foreign Subsidiary (which Schedule
  5(d) may be supplemented from time to time in connection with a pledge
  hereunder of Pledged Shares of a new Foreign Subsidiary) and provided that
  with respect to any matters disclosed on Schedule 5(d) Pledgor shall as
  soon as reasonably practicable obtain all such authorizations and
  approvals, make all such notifications or filings and take all such other
  actions as may be so disclosed and required under the laws governing such
  Foreign Subsidiary in connection with the actions described in the
  following clauses (i)-(iii), no authorization, approval or other action by,
  and no notice to or filing with, any governmental authority or regulatory
  body is required for either (i) the pledge by Pledgor of the Pledged
  Collateral pursuant to this Agreement and the grant by Pledgor of the
  security interest granted hereby, (ii) the execution, delivery or
  performance of this Agreement by Pledgor, or (iii) the exercise by
  Collateral Agent of the voting or other rights, or the remedies in respect
  of the Pledged Collateral, provided for in this Agreement (except as may be
  required in connection with a disposition of Pledged Collateral by laws
  affecting the offering and sale of securities generally).
 
    (e) Perfection. The pledge of the Pledged Collateral pursuant to this
  Agreement creates a valid and perfected and, except as otherwise permitted
  under the Revolving Credit Agreement or the Term Loan Agreement, as the
  case may be, first priority security interest in the Pledged Collateral,
  securing the payment of the Secured Obligations.
 
    (f) Margin Regulations. The pledge of the Pledged Collateral pursuant to
  this Agreement does not violate Regulation G, T, U or X of the Board of
  Governors of the Federal Reserve System.
 
    (g) Other Information. All information heretofore, herein or hereafter
  supplied to Collateral Agent by or on behalf of Pledgor with respect to the
  Pledged Collateral is accurate and complete in all material respects.
 
  SECTION 6. Transfers and Other Liens; Additional Pledged Collateral;
etc. Pledgor shall:
 
    (a) not, except as expressly permitted by Section 8.7 of the Revolving
  Credit Agreement and Section 8.7 of the Term Loan Agreement, (i) sell,
  assign (by operation of law or otherwise) or otherwise dispose of, or grant
  any option with respect to, any of the Pledged Collateral, (ii) create or
  suffer to exist any Lien upon or with respect to any of the Pledged
  Collateral, except for the security interest under this Agreement, or (iii)
  permit any issuer of Pledged Shares to merge or consolidate unless all the
  outstanding capital stock of the surviving or resulting corporation is,
  upon such merger or consolidation, pledged hereunder and no cash,
  securities or other property is distributed in respect of the outstanding
  shares of any other constituent corporation; provided that in the event
  Pledgor makes a sale or disposition permitted by the Revolving Credit
  Agreement and the Term Loan Agreement and the assets subject to such sale
  or disposition are Pledged Shares, Collateral Agent shall release the
  Pledged Shares that are the subject of such sale or disposition to Pledgor
  free and clear of the lien and security interest under this Agreement
  concurrently with the consummation of such sale or disposition; provided,
  further that, as a condition precedent to such release, Collateral Agent
  shall have received evidence satisfactory to it that arrangements
  satisfactory to it have been made for delivery to the Revolving Agent and
  the Term Agent of the proceeds of such sale or disposition to the extent
  required by the Revolving Credit Agreement and the Term Loan Agreement;
 
    (b)(i) cause each issuer of Pledged Shares not to issue any Stock or
  other securities in addition to or in substitution for the Pledged Shares
  issued by such issuer, except to Pledgor, and (ii) pledge hereunder,
  immediately upon its acquisition (directly or indirectly) thereof, any and
  all additional shares of Stock or other securities of each issuer of
  Pledged Shares, (iii) pledge hereunder, immediately upon its acquisition
  (directly or indirectly) thereof, any and all shares of Stock of any Person
  that, after the date of this Agreement, becomes, as a result of any
  occurrence, a First-Tier wholly-owned Domestic Subsidiary of Pledgor, and
  (iv) pledge hereunder, immediately upon its acquisition (directly or
  indirectly) thereof, the
<PAGE>
 
  Maximum Percentage of shares of Stock or any Person that, after the date of
  this Agreement, becomes, as a result of any occurrence, a First-Tier
  Foreign Subsidiary of Pledgor;
 
    (c) promptly notify Collateral Agent of any event of which Pledgor
  becomes aware causing loss of the Pledged Collateral;
 
    (d) promptly deliver to Collateral Agent all written notices received by
  it with respect to the Pledged Collateral; and
 
    (e) pay promptly when due all taxes, assessments and governmental charges
  or levies imposed upon, and all claims against, the Pledged Collateral,
  except to the extent the validity thereof is being contested in good faith;
  provided that Pledgor shall in any event pay such taxes, assessments,
  charges, levies or claims not later than five days prior to the date of any
  proposed sale under any judgment, writ or warrant of attachment entered or
  filed against Pledgor or any of the Pledged Collateral as a result of the
  failure to make such payment.
 
  SECTION 7. Further Assurances; Pledge Amendments.
 
  (a) Pledgor agrees that from time to time, at the expense of Pledgor, Pledgor
will promptly execute and deliver all further instruments and documents, and
take all further action, that may be necessary or desirable, or that Collateral
Agent may request, in order to perfect and protect any security interest
granted or purported to be granted hereby or to enable Collateral Agent to
exercise and enforce its rights and remedies hereunder with respect to any
Pledged Collateral. Without limiting the generality of the foregoing, Pledgor
will: (i) execute and file such financing or continuation statements, or
amendments thereto, and such other instruments or notices, as may be necessary
or desirable, or as Collateral Agent may request, in order to perfect and
preserve the security interests granted or purported to be granted hereby and
(ii) at Collateral Agent's request, appear in and defend any action or
proceeding that may affect Pledgor's title to or Collateral Agent's security
interest in all or any part of the Pledged Collateral.
 
  (b) Pledgor further agrees that it will, upon obtaining any additional shares
of Stock or other securities required to be pledged hereunder as provided in
Section 6(b), promptly (and in any event within thirty Business Days) deliver
to Collateral Agent a Pledge Amendment, duly executed by Pledgor, in
substantially the form of Schedule II annexed hereto (a "Pledge Amendment"), in
respect of the additional Pledged Shares to be pledged pursuant to this
Agreement. Pledgor hereby authorizes Collateral Agent to attach each Pledge
Amendment to this Agreement and agrees that all Pledged Shares listed on any
Pledge Amendment delivered to Collateral Agent shall for all purposes hereunder
be considered Pledged Collateral; provided that the failure of Pledgor to
execute a Pledge Amendment with respect to any additional Pledged Shares
pledged pursuant to this Agreement shall not impair the security interest of
Collateral Agent therein or otherwise adversely affect the rights and remedies
of Collateral Agent hereunder with respect thereto.
 
  SECTION 8. Voting Rights; Dividends; Etc.
 
  (a) So long as no Event of Default shall have occurred and be continuing:
 
    (i) Pledgor shall be entitled to exercise any and all voting and other
  consensual rights pertaining to the Pledged Collateral or any part thereof
  for any purpose not inconsistent with the terms of this Agreement, the
  Revolving Credit Agreement or the Term Loan Agreement; provided, however,
  that Pledgor shall not exercise or refrain from exercising any such right
  if Collateral Agent shall have notified Pledgor that, in Collateral Agent's
  judgment, such action would have a material adverse effect on the value of
  the Pledged Collateral or any part thereof; and provided, further, that
  Pledgor shall give Collateral Agent at least five Business Days' prior
  written notice of the manner in which it intends to exercise, or the
  reasons for refraining from exercising, any such right. It is understood,
  however, that neither (A) the voting by Pledgor of any Pledged Shares for
  or Pledgor's consent to the election of directors at a regularly scheduled
  annual or other meeting of stockholders or with respect to incidental
  matters at any such meeting nor (B) Pledgor's consent to or approval of any
  action otherwise permitted under this Agreement, the Revolving Credit
  Agreement and the Term Loan Agreement shall be deemed inconsistent with the
  terms of this Agreement, the Revolving Credit Agreement or the Term Loan
  Agreement within the
<PAGE>
 
  meaning of this Section 8(a)(i), and no notice of any such voting or
  consent need be given to Collateral Agent;
 
    (ii) Pledgor shall be entitled to receive and retain, and to utilize free
  and clear of the lien of this Agreement, any and all dividends and interest
  paid in respect of the Pledged Collateral; provided, however, that any and
  all
 
      (A) dividends and interest paid or payable other than in cash in
    respect of, and instruments and other property received, receivable or
    otherwise distributed in respect of, or in exchange for, any Pledged
    Collateral,
 
      (B) dividends and other distributions paid or payable in cash in
    respect of any Pledged Collateral in connection with a partial or total
    liquidation or dissolution or in connection with a reduction of
    capital, capital surplus or paid-in-surplus, and
 
      (C) cash paid, payable or otherwise distributed in respect of
    principal or in redemption of or in exchange for any Pledged
    Collateral,
 
shall be, and shall forthwith be delivered to Collateral Agent to hold as,
Pledged Collateral and shall, if received by Pledgor, be received in trust for
the benefit of Collateral Agent, be segregated from the other property or funds
of Pledgor and be forthwith delivered to Collateral Agent as Pledged Collateral
in the same form as so received (with all necessary indorsements); and
 
    (iii) Collateral Agent shall promptly execute and deliver (or cause to be
  executed and delivered) to Pledgor all such proxies, dividend payment
  orders and other instruments as Pledgor may from time to time reasonably
  request for the purpose of enabling Pledgor to exercise the voting and
  other consensual rights which it is entitled to exercise pursuant to
  paragraph (i) above and to receive the dividends, principal or interest
  payments which it is authorized to receive and retain pursuant to paragraph
  (ii) above.
 
  (b) Upon the occurrence and during the continuation of an Event of Default:
 
    (i) upon written notice from Collateral Agent to Pledgor, all rights of
  Pledgor to exercise the voting and other consensual rights which it would
  otherwise be entitled to exercise pursuant to Section 8(a)(i) shall cease,
  and all such rights shall thereupon become vested in Collateral Agent which
  shall thereupon have the sole right to exercise such voting and other
  consensual rights;
 
    (ii) all rights of Pledgor to receive the dividends and interest payments
  which it would otherwise be authorized to receive and retain pursuant to
  Section 8(a)(ii) shall cease, and all such rights shall thereupon become
  vested in Collateral Agent which shall thereupon have the sole right to
  receive and hold as Pledged Collateral such dividends and interest
  payments; and
 
    (iii) all dividends, principal and interest payments which are received
  by Pledgor contrary to the provisions of paragraph (ii) of this Section
  8(b) shall be received in trust for the benefit of Collateral Agent, shall
  be segregated from other funds of Pledgor and shall forthwith be paid over
  to Collateral Agent as Pledged Collateral in the same form as so received
  (with any necessary indorsements).
 
  (c) In order to permit Collateral Agent to exercise the voting and other
consensual rights which it may be entitled to exercise pursuant to Section
8(b)(i) and to receive all dividends and other distributions which it may be
entitled to receive under Section 8(a)(ii) or Section 8(b)(ii), (i) Pledgor
shall promptly execute and deliver (or cause to be executed and delivered) to
Collateral Agent all such proxies, dividend payment orders and other
instruments as Collateral Agent may from time to time reasonably request and
(ii) without limiting the effect of the immediately preceding clause (i),
Pledgor hereby grants to Collateral Agent an irrevocable proxy to vote the
Pledged Shares and to exercise all other rights, powers, privileges and
remedies to which a holder of the Pledged Shares would be entitled (including,
without limitation, giving or withholding written consents of shareholders,
calling special meetings of shareholders and voting at such meetings), which
proxy shall be effective, automatically and without the necessity of any action
(including any transfer of any Pledged Shares on the record books of the issuer
thereof) by any other Person (including the issuer of the Pledged Shares or any
officer or agent thereof), upon the occurrence of an Event of Default and which
proxy shall only terminate upon the payment in full of the Secured Obligations.

  SECTION 9. Collateral Agent Appointed Attorney-in-Fact. Pledgor hereby
irrevocably appoints Collateral Agent as Pledgor's attorney-in-fact, with full
authority in the place and stead of Pledgor and in the name of Pledgor,
Collateral Agent or otherwise, from time to time in Collateral Agent's
discretion to take any action and to execute any instrument that Collateral
Agent may deem necessary or advisable to accomplish the purposes of this
Agreement, including without limitation:
 
    (a) to file one or more financing or continuation statements, or
  amendments thereto, relative to all or any part of the Pledged Collateral
  without the signature of Pledgor;
 
    (b) after and during the continuance of an Event of Default, to ask,
  demand, collect, sue for, recover, compound, receive and give acquittance
  and receipts for moneys due and to become due under or in respect of any of
  the Pledged Collateral;
 
    (c) after and during the continuance of an Event of Default, to receive,
  endorse and collect any instruments made payable to Pledgor representing
  any dividend, principal or interest payment or other distribution in
  respect of the Pledged Collateral or any part thereof and to give full
  discharge for the same; and
 
    (d) after and during the continuance of an Event of Default, to file any
  claims or take any action or institute any proceedings that Collateral
  Agent may deem necessary or desirable for the collection of any of the
  Pledged Collateral or otherwise to enforce the rights of Collateral Agent
  with respect to any of the Pledged Collateral.
 
  SECTION 10. Collateral Agent May Perform. If Pledgor fails to perform any
agreement contained herein after the period in which such performance is
required, Collateral Agent may itself perform, or cause performance of, such
agreement, and the expenses of Collateral Agent incurred in connection
therewith shall be payable by Pledgor under Section 15(b).
 
  SECTION 11. Standard of Care. The powers conferred on Collateral Agent
hereunder are solely to protect its interest in the Pledged Collateral and
shall not impose any duty upon it to exercise any such powers. Except for the
exercise of reasonable care in the custody of any Pledged Collateral in its
possession and the accounting for moneys actually received by it hereunder,
Collateral Agent shall have no duty as to any Pledged Collateral, it being
understood that Collateral Agent shall have no responsibility for (a)
ascertaining or taking action with respect to calls, conversions, exchanges,
maturities, tenders or other matters relating to any Pledged Collateral,
whether or not Collateral Agent has or is deemed to have knowledge of such
matters, (b) taking any necessary steps (other than steps taken in accordance
with the standard of care set forth above to maintain possession of the Pledged
Collateral) to preserve rights against any parties with respect to any Pledged
Collateral, (c) taking any necessary steps to collect or realize upon the
Secured Obligations or any guarantee therefor, or any part thereof, or any of
the Pledged Collateral, or (d) initiating any action to protect the Pledged
Collateral against the possibility of a decline in market value. Collateral
Agent shall be deemed to have exercised reasonable care in the custody and
preservation of Pledged Collateral in its possession if such Pledged Collateral
is accorded treatment substantially equal to that which Collateral Agent
accords its own property consisting of negotiable securities.
 
  SECTION 12. Remedies.
 
  (a) If any Event of Default shall have occurred and be continuing, Collateral
Agent may exercise in respect of the Pledged Collateral, in addition to all
other rights and remedies provided for herein or otherwise available to it, all
the rights and remedies of a secured party on default under the Uniform
Commercial Code as in effect in any relevant jurisdiction (the "UCC") (whether
or not the UCC applies to the affected Pledged Collateral), and Collateral
Agent may also in its sole discretion, without notice except as specified
below, sell the Pledged Collateral or any part thereof in one or more parcels
at public or private sale, at any exchange or broker's board or at any of
Collateral Agent's offices or elsewhere, for cash, on credit or for future
delivery, at such time or times and at such price or prices and upon such other
terms as Collateral Agent may deem commercially reasonable, irrespective of the
impact of any such sales on the market price of the Pledged
 
                                       8
<PAGE>
 
Collateral. Collateral Agent may be the purchaser of any or all of the Pledged
Collateral at any such public sale and, to the extent permitted by law, private
sale, and Collateral Agent, as agent for and representative of Secured Parties
(but not any Secured Party or Secured Parties in its or their respective
individual capacities unless Requisite Obligees shall otherwise agree in
writing), shall be entitled, for the purpose of bidding and making settlement
or payment of the purchase price for all or any portion of the Pledged
Collateral sold at any such public sale, to use and apply any of the Secured
Obligations as a credit on account of the purchase price for any Pledged
Collateral payable by Collateral Agent at such sale. Each purchaser at any such
sale shall hold the property sold absolutely free from any claim or right on
the part of Pledgor, and Pledgor hereby waives (to the extent permitted by
applicable law) all rights of redemption, stay and/or appraisal which it now
has or may at any time in the future have under any rule of law or statute now
existing or hereafter enacted. Pledgor agrees that, to the extent notice of
sale shall be required by law, at least ten days' notice to Pledgor of the time
and place of any public sale or the time after which any private sale is to be
made shall constitute reasonable notification. Collateral Agent shall not be
obligated to make any sale of Pledged Collateral regardless of notice of sale
having been given. Collateral Agent may adjourn any public or private sale from
time to time by announcement at the time and place fixed therefor, and such
sale may, without further notice, be made at the time and place to which it was
so adjourned. Pledgor hereby waives any claims against Collateral Agent arising
by reason of the fact that the price at which any Pledged Collateral may have
been sold at such a private sale was less than the price which might have been
obtained at a public sale, even if Collateral Agent accepts the first offer
received and does not offer such Pledged Collateral to more than one offeree.
If the proceeds of any sale or other disposition of the Pledged Collateral are
insufficient to pay all the Secured Obligations, Pledgor shall be liable for
the deficiency and the fees of any attorneys employed by Collateral Agent to
collect such deficiency.
 
  (b) Pledgor recognizes that, by reason of certain prohibitions contained in
the Securities Act of 1933, as from time to time amended (the "Securities
Act"), and applicable state securities laws, Collateral Agent may be compelled,
with respect to any sale of all or any part of the Pledged Collateral conducted
without prior registration or qualification of such Pledged Collateral under
the Securities Act and/or such state securities laws, to limit purchasers to
those who will agree, among other things, to acquire the Pledged Collateral for
their own account, for investment and not with a view to the distribution or
resale thereof. Pledgor acknowledges that any such private sales may be at
prices and on terms less favorable than those obtainable through a public sale
without such restrictions (including, without limitation, a public offering
made pursuant to a registration statement under the Securities Act) and,
notwithstanding such circumstances and the registration rights granted to
Collateral Agent by Pledgor pursuant to Section 13, Pledgor agrees that the
effect of the foregoing in respect of any such private sale shall not be deemed
per se to cause such private sale to have not been made in a commercially
reasonable manner and that Collateral Agent shall have no obligation to engage
in public sales and no obligation to delay the sale of any Pledged Collateral
for the period of time necessary to permit the issuer thereof to register it
for a form of public sale requiring registration under the Securities Act or
under applicable state securities laws, even if such issuer would, or should,
agree to so register it.
 
  (c) If Collateral Agent determines to exercise its right to sell any or all
of the Pledged Collateral, upon written request, Pledgor shall and shall cause
each issuer of any Pledged Shares to be sold hereunder from time to time to
furnish to Collateral Agent all such information as Collateral Agent may
request in order to determine the number of shares and other instruments
included in the Pledged Collateral which may be sold by Collateral Agent in
exempt transactions under the Securities Act and the rules and regulations of
the SEC thereunder, as the same are from time to time in effect.
 
  SECTION 13. Registration Rights. If Collateral Agent shall determine to
exercise its right to sell all or any of the Pledged Collateral pursuant to
Section 12, Pledgor agrees that, upon request of Collateral Agent (which
request may be made by Collateral Agent in its sole discretion), Pledgor will,
at its own expense:
 
    (a) execute and deliver, and use its best efforts to cause each issuer of
  the Pledged Collateral contemplated to be sold and the directors and
  officers thereof to execute and deliver, all such instruments and
  documents, and do or cause to be done all such other acts and things, as
  may be necessary or, in the
 
                                       9
<PAGE>
 
  opinion of Collateral Agent, advisable to file a registration statement
  covering such Pledged Collateral under the provisions of the Securities Act
  and to use its best efforts to cause the registration statement relating
  thereto to become effective and to remain effective for such period as
  prospectuses are required by law to be furnished, and to make all
  amendments and supplements thereto and to the related prospectus which, in
  the opinion of Collateral Agent, are necessary or advisable, all in
  conformity with the requirements of the Securities Act and the rules and
  regulations of the SEC applicable thereto;
 
    (b) use its best efforts to qualify the Pledged Collateral under all
  applicable state securities or "Blue Sky" laws and to obtain all necessary
  governmental approvals for the sale of the Pledged Collateral, as requested
  by Collateral Agent;
 
    (c) cause each such issuer to make available to its security holders, as
  soon as practicable, an earnings statement which will satisfy the
  provisions of Section 11(a) of the Securities Act;
 
    (d) use its best efforts to do or cause to be done all such other acts
  and things as may be necessary to make such sale of the Pledged Collateral
  or any part thereof valid and binding and in compliance with applicable
  law; and
 
    (e) bear all costs and expenses, including reasonable attorneys' fees, of
  carrying out its obligations under this Section 13.
 
  Pledgor further agrees that a breach of any of the covenants contained in
this Section 13 will cause irreparable injury to Collateral Agent, that
Collateral Agent has no adequate remedy at law in respect of such breach and,
as a consequence, that each and every covenant contained in this Section 13
shall be specifically enforceable against Pledgor, and Pledgor hereby waives
and agrees not to assert any defenses against an action for specific
performance of such covenants except for a defense that no default has occurred
giving rise to the Secured Obligations becoming due and payable prior to their
stated maturities. Nothing in this Section 13 shall in any way alter the rights
of Collateral Agent under Section 12.
 
  SECTION 14. Application of Proceeds. Except as expressly provided elsewhere
in this Agreement, all proceeds received by Collateral Agent in respect of any
sale of, collection from, or other realization upon all or any part of the
Pledged Collateral may, in the discretion of Collateral Agent, be held by
Collateral Agent as Pledged Collateral for, and/or then, or at any time
thereafter, applied in full or in part by Collateral Agent against, the Secured
Obligations in the following order of priority:
 
    First: To the payment of all costs and expenses of such sale, collection
  or other realization, including reasonable compensation to Collateral Agent
  and its agents and counsel, and all other expenses, liabilities and
  advances made or incurred by Collateral Agent in connection therewith, and
  all amounts for which Collateral Agent is entitled to indemnification
  hereunder and all advances made by Collateral Agent hereunder for the
  account of Pledgor, and to the payment of all costs and expenses paid or
  incurred by Collateral Agent in connection with the exercise of any right
  or remedy hereunder, all in accordance with Section 15;
 
    Second: To the payment of all other Secured Obligations in the order
  described in Section 3 of the Intercreditor Agreement; and
 
    Third: To the payment to or upon the order of Pledgor, or to whosoever
  may be lawfully entitled to receive the same or as a court of competent
  jurisdiction may direct, of any surplus then remaining from such proceeds.
 
  SECTION 15. Indemnity and Expenses.
 
    (a) Pledgor agrees to indemnify Collateral Agent and each other Secured
  Party from and against any and all claims, losses and liabilities in any
  way relating to, growing out of or resulting from this Agreement and the
  transactions contemplated hereby (including, without limitation,
  enforcement of this Agreement), except to the extent such claims, losses or
  liabilities result solely from Collateral Agent's or such other Secured
  Party's gross negligence or willful misconduct as finally determined by a
  court of competent jurisdiction.
 
                                       10
<PAGE>
 
  (b) Pledgor shall pay to Collateral Agent upon demand the amount of any and
all costs and expenses, including the reasonable fees and expenses of its
counsel and of any experts and agents, that Collateral Agent may incur in
connection with (i) the administration of this Agreement, (ii) the custody or
preservation of, or the sale of, collection from, or other realization upon,
any of the Pledged Collateral, (iii) the exercise or enforcement of any of the
rights of Collateral Agent hereunder, or (iv) the failure by Pledgor to perform
or observe any of the provisions hereof.
 
  (c) In the event of any public sale described in Section 13, Pledgor agrees
to indemnify and hold harmless Collateral Agent and each of Collateral Agent's
directors, officers, employees and agents from and against any loss, fee, cost,
expense, damage, liability or claim, joint or several, to which Collateral
Agent or such other persons may become subject or for which any of them may be
liable, under the Securities Act or otherwise, insofar as such losses, fees,
costs, expenses, damages, liabilities or claims (or any litigation commenced or
threatened in respect thereof) arise out of or are based upon an untrue
statement or alleged untrue statement of a material fact contained in any
preliminary prospectus, registration statement, prospectus or other such
document published or filed in connection with such public sale, or any
amendment or supplement thereto, 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 Collateral Agent and such other persons for any legal or other
expenses reasonably incurred by Collateral Agent and such other persons in
connection with any litigation, of any nature whatsoever, commenced or
threatened in respect thereof (including without limitation any and all fees,
costs and expenses whatsoever reasonably incurred by Collateral Agent and such
other persons and counsel for Collateral Agent and such other persons in
investigating, preparing for, defending against or providing evidence,
producing documents or taking any other action in respect of, any such
commenced or threatened litigation or any claims asserted). This indemnity
shall be in addition to any liability which Pledgor may otherwise have and
shall extend upon the same terms and conditions to each person, if any, that
controls Collateral Agent or such persons within the meaning of the Securities
Act.
 
  SECTION 16. Suretyship Waivers; Other Limitations.
 
  (a) Pledgor agrees that its obligations hereunder are irrevocable, absolute,
independent and unconditional and shall not be affected by any circumstance
which constitutes a legal or equitable discharge of a guarantor or surety other
than payment in full of the Underlying Debt. In furtherance of the foregoing
and without limiting the generality thereof, Pledgor agrees as follows: (i)
Collateral Agent or any other Secured Party may from time to time, without
notice or demand and without affecting the validity or enforceability of this
Agreement or giving rise to any limitation, impairment or discharge of
Pledgor's liability hereunder, (A) renew, extend, accelerate or otherwise
change the time, place, manner or terms of payment of the Underlying Debt, (B)
settle, compromise, release or discharge, or accept or refuse any offer of
performance with respect to, or substitutions for, the Underlying Debt or any
agreement relating thereto and/or subordinate the payment of the same to the
payment of any other obligations, (C) request and accept guaranties of the
Underlying Debt and take and hold other security for the payment of the
Underlying Debt, (D) release, exchange, compromise, subordinate or modify, with
or without consideration, any other security for payment of the Underlying
Debt, any guaranties of the Underlying Debt, or any other obligation of any
Person with respect to the Underlying Debt, (E) enforce and apply any other
security now or hereafter held by or for the benefit of Collateral Agent or any
other Secured Party in respect of the Underlying Debt and direct the order or
manner of sale thereof, or exercise any other right or remedy that Collateral
Agent or other Secured Parties, or any of them, may have against any such
security, as Collateral Agent in its discretion may determine consistent with
the Revolving Credit Agreement and any applicable security agreement, including
foreclosure on any such security pursuant to one or more judicial or
nonjudicial sales, whether or not every aspect of any such sale is commercially
reasonable, and (F) exercise any other rights available to Collateral Agent or
other Secured Parties, or any of them, under the Financing Documents, at law or
in equity; and (ii) this Agreement and the obligations of Pledgor hereunder
shall be valid and enforceable and shall not be subject to any limitation,
impairment or discharge for any reason (other than payment in full of the
Underlying Debt), including without limitation the occurrence of any of the
following, whether or not Pledgor shall have had notice or knowledge of any of
them: (A) any failure to assert
 
                                       11
<PAGE>
 
or enforce or agreement not to assert or enforce, or the stay or enjoining, by
order of court, by operation of law or otherwise, of the exercise or
enforcement of, any claim or demand or any right, power or remedy with respect
to the Underlying Debt or any agreement relating thereto, or with respect to
any guaranty of or other security for the payment of the Underlying Debt, (B)
any rescission, waiver, amendment or modification of, or any consent to
departure from, any of the terms or provisions (including without limitation
provisions relating to events of default) of any of the Financing Documents or
any agreement or instrument executed pursuant thereto, or of any guaranty or
other security for the Underlying Debt, in each case whether or not in
accordance with the terms of any Financing Document or any agreement relating
to such guaranty or other security, (C) the Underlying Debt, or any agreement
relating thereto, at any time being found to be illegal, invalid or
unenforceable in any respect, (D) the application of payments received from any
source (other than payments received pursuant to the other Financing Documents
or from the proceeds of any security for the Secured Obligations, except to the
extent such security also serves as collateral for indebtedness other than the
Secured Obligations) to the payment of indebtedness other than the Underlying
Debt, even though Collateral Agent or other Secured Parties, or any of them,
might have elected to apply such payment to any part or all of the Underlying
Debt, (E) any Secured Party's consent to the change, reorganization or
termination of the corporate or other structure or existence of Borrower or any
of its Subsidiaries and to any corresponding restructuring of the Secured
Obligations; (F) any failure to perfect or continue perfection of a security
interest in any other collateral which secures any of the Underlying Debt, (G)
any defenses, set-offs or counterclaims which Borrower may allege or assert
against Collateral Agent or any other Secured Party in respect of the
Underlying Debt, including but not limited to failure of consideration, breach
of warranty, payment, statute of frauds, statute of limitations, accord and
satisfaction and usury, and (H) any other act or thing or omission, or delay to
do any other act or thing, which may or might in any manner or to any extent
vary the risk of Pledgor as an obligor in respect of the Underlying Debt.
 
  (b) Pledgor hereby waives, for the benefit of other Secured Parties and
Collateral Agent: (i) any right to require Collateral Agent or other Secured
Parties, as a condition of payment or performance by Pledgor, to (A) proceed
against Borrower, any guarantor of the Underlying Debt or any other Person, (B)
proceed against or exhaust any other security held from Borrower, any guarantor
of the Underlying Debt or any other Person, (C) proceed against or have resort
to any balance of any deposit account or credit on the books of Collateral
Agent or any other Secured Party in favor of Borrower or any other Person, or
(D) pursue any other remedy in the power of Collateral Agent or any other
Secured Party whatsoever; (ii) any defense arising by reason of the incapacity,
lack of authority or any disability or other defense of Borrower including,
without limitation, any defense based on or arising out of the lack of validity
or the unenforceability of the Underlying Debt or any agreement or instrument
relating thereto or by reason of the cessation of the liability of Borrower
from any cause other than payment in full of the Underlying Debt; (iii) 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; (iv) any defense based upon
Collateral Agent's or any other Secured Party's errors or omissions in the
administration of the Underlying Debt, except behavior which amounts to bad
faith; (v) (A) any principles or provisions of law, statutory or otherwise,
which are or might be in conflict with the terms of this Agreement and any
legal or equitable discharge of Pledgor's obligations hereunder, (B) the
benefit of any statute of limitations affecting Pledgor's liability hereunder
or the enforcement hereof, (C) any rights to set-offs, recoupments and
counterclaims, and (D) promptness, diligence and any requirement that
Collateral Agent or any other Secured Party protect, secure, perfect or insure
any other security interest or lien or any property subject thereto; (vi)
notices, demands, presentments, protests, notices of protest, notices of
dishonor and notices of any action or inaction, notices of default under the
Revolving Credit Agreement, the Term Loan Agreement or any agreement or
instrument related thereto, notices of any renewal, extension or modification
of the Underlying Debt or any agreement related thereto, notices of any
extension of credit to Borrower and notices of any of the matters referred to
in the preceding paragraph and any right to consent to any thereof; and (vii)
to the fullest extent permitted by law, any defenses or benefits that may be
derived from or afforded by law which limit the liability of or exonerate
guarantors or sureties, or which may conflict with the terms of this Agreement.
 
                                       12
<PAGE>
 
  (c) Until the Underlying Debt shall have been paid in full and the
commitments to extend credit under the Financing Documents shall have
terminated and all Letters of Credit shall have expired or been cancelled,
Pledgor shall withhold exercise of (i) any claim, right or remedy, direct or
indirect, that Pledgor now has or may hereafter have against Borrower or any of
its assets in connection with this Agreement or the performance by Pledgor of
its obligations hereunder, in each case whether such claim, right or remedy
arises in equity, under contract, by statute (including without limitation
under California Civil Code Section 2847, 2848 or 2849), under common law or
otherwise and including without limitation (A) any right of subrogation,
reimbursement or indemnification that Pledgor now has or may hereafter have
against Borrower, (B) any right to enforce, or to participate in, any claim,
right or remedy that Collateral Agent or any Secured Party now has or may
hereafter have against Borrower, and (C) any benefit of, and any right to
participate in, any other collateral or security now or hereafter held by
Collateral Agent or any other Secured Party, and (ii) any right of contribution
Pledgor may have against any guarantor of any of the Underlying Debt. Pledgor
further agrees that, to the extent the waiver of its rights of subrogation,
reimbursement, indemnification and contribution as set forth herein is found by
a court of competent jurisdiction to be void or voidable for any reason, any
rights of subrogation, reimbursement or indemnification Pledgor may have
against Borrower or against any other collateral or security, and any rights of
contribution Pledgor may have against any such guarantor, shall be junior and
subordinate to any rights Collateral Agent or other Secured Parties may have
against Borrower, to all right, title and interest Collateral Agent or other
Secured Parties may have in any such other collateral or security, and to any
right Collateral Agent or other Secured Parties may have against any such
guarantor.
 
  (d) Other Secured Parties and Collateral Agent shall have no obligation to
disclose or discuss with Pledgor their assessment, or Pledgor's assessment, of
the financial condition of Borrower. Pledgor has adequate means to obtain
information from Borrower on a continuing basis concerning the financial
condition of Borrower and its ability to perform its obligations under the
Financing Documents, and Pledgor assumes the responsibility for being and
keeping informed of the financial condition of Borrower and of all
circumstances bearing upon the risk of nonpayment of the Underlying Debt.
Pledgor hereby waives and relinquishes any duty on the part of Collateral Agent
or any other Secured Party to disclose any matter, fact or thing relating to
the business, operations or condition of Borrower now known or hereafter known
by Collateral Agent or any other Secured Party.
 
  (e) As used in this subsection 16(f), any reference to "the principal"
includes Borrower, and any reference to "the creditor" includes each Secured
Party. In accordance with Section 2856 of the California Civil Code:
 
    (i) each Pledgor agrees (i) to waive any and all rights of subrogation
  and reimbursement against Borrower or against any collateral or security
  granted by Borrower for any of the Secured Obligations and (ii) to withhold
  the exercise of any and all rights of subrogation, reimbursement and
  contribution against Borrower, against any other provider of collateral
  support for the Secured Obligations and against any collateral or security
  granted by any such other provider of collateral support for the Secured
  Obligations until the Secured Obligations shall have been paid in full and
  the Revolving Credit Commitments, the Swing Line Commitment and the Term
  Loan Commitments shall have terminated and all Letters of Credit shall have
  expired or been cancelled;
 
    (ii) each Pledgor waives any and all other rights and defenses available
  to such Pledgor by reason of Sections 2787 to 2855, inclusive, 2899 and
  3433 of the California Civil Code, including without limitation any and all
  rights or defenses such Pledgor may have by reason of protection afforded
  to the principal with respect to any of the Secured Obligations, or to any
  other provider of collateral support for the Secured Obligations or
  guarantor of any of the Secured Obligations (including any other Pledgor)
  with respect to any of such Person's credit support obligations, in either
  case pursuant to the antideficiency or other laws of the State of
  California limiting or discharging the principal's indebtedness or such
  Person's credit support obligations, including without limitation Section
  580a, 580b, 580d, or 726 of the California Code of Civil Procedure; and
 
                                       13
<PAGE>
 
    (iii) each Pledgor waives all rights and defenses arising out of an
  election of remedies by the creditor, even though that election of
  remedies, such as a nonjudicial foreclosure with respect to security for
  any Secured Obligation, has destroyed such Pledgor's rights of subrogation
  and reimbursement against the principal by the operation of Section 580d of
  the California Code of Civil Procedure or otherwise; and even though that
  election of remedies by the creditor, such as nonjudicial foreclosure with
  respect to security for an obligation of any other provider of collateral
  support for the Secured Obligations or guarantor of any of the Secured
  Obligations (including any other Pledgor), has destroyed such Pledgor's
  rights of contribution against such other Person.
 
  No other provision of this Agreement shall be construed as limiting the
generality of any of the covenants and waivers set forth in this subsection
16(f). In accordance with subsection 25 below, this Agreement shall be governed
by, and shall be construed and enforced in accordance with, the internal laws
of the State of New York, without regard to conflicts of laws principles. This
subsection 16(f) is included solely out of an abundance of caution, and shall
not be construed to mean that any of the above-referenced provisions of
California law are in any way applicable to this Agreement or to any of the
Secured Obligations.
 
  (f) Anything contained in this Agreement to the contrary notwithstanding, if
any Fraudulent Transfer Law (as hereinafter defined) is determined by a court
of competent jurisdiction to be applicable to the obligations of any Pledgor
under this Agreement, such obligations of such Pledgor hereunder shall be
limited to a maximum aggregate amount equal to the largest amount that would
not render its obligations hereunder subject to avoidance as a fraudulent
transfer or conveyance under Section 548 of Title 11 of the United States Code
or any applicable provisions of comparable state law (collectively, the
"Fraudulent Transfer Laws"), in each case after giving effect to all other
liabilities of such Pledgor, contingent or otherwise, that are relevant under
the Fraudulent Transfer Laws (specifically excluding, however, any liabilities
of such Pledgor (x) in respect of intercompany indebtedness to Borrower or
other affiliates of Borrower to the extent that such indebtedness would be
discharged in an amount equal to the value contributed by such Pledgor
hereunder and (y) under any credit support of Subordinated Indebtedness which
credit support contains a limitation as to maximum amount similar to that set
forth in this subsection, pursuant to which the liability of such Pledgor
hereunder is included in the liabilities taken into account in determining such
maximum amount) and after giving effect as assets to the value (as determined
under the applicable provisions of the Fraudulent Transfer Laws) of any rights
to subrogation, reimbursement, indemnification or contribution of such Pledgor
pursuant to applicable law or pursuant to the terms of any agreement.
 
  SECTION 17. Continuing Security Interest; Transfer of Loans. This Agreement
shall create a continuing security interest in the Pledged Collateral and shall
(a) remain in full force and effect until either (i) the payment in full of all
Secured Obligations, the cancellation or termination of the Revolving Credit
Commitments, the Swing Line Commitment, the Term Loan Commitments and the
cancellation or expiration of all outstanding Letters of Credit or (ii) the
termination of this Agreement pursuant to Section 18, (b) be binding upon
Pledgor, its successors and assigns, and (c) inure, together with the rights
and remedies of Collateral Agent hereunder, to the benefit of Collateral Agent
and its successors, transferees and assigns. Without limiting the generality of
the foregoing clause (c), but subject to the provisions of Section 11.7 of the
Revolving Credit Agreement and Section 11.7 of the Term Loan Agreement, any
Secured Party may assign or otherwise transfer any Secured Obligations held by
it to any other Person, and such other Person shall thereupon become vested
with all the benefits in respect thereof granted to Secured Parties herein or
otherwise. Upon either (i) the payment in full of all Secured Obligations, the
cancellation or termination of the Revolving Credit Commitments, the Swing Line
Commitment, the Term Loan Commitments and the cancellation or expiration of all
outstanding Letters of Credit or (ii) the termination of this Agreement
pursuant to Section 18, the security interest granted hereby shall terminate
and all rights to the Pledged Collateral shall revert to Pledgor. Upon any such
termination Collateral Agent will, at Pledgor's expense, execute and deliver to
Pledgor such documents as Pledgor shall reasonably request to evidence such
termination and Pledgor shall be entitled to the return, upon its request and
at its expense, against receipt and without recourse to Collateral Agent, of
such of the Pledged Collateral as shall not have been sold or otherwise applied
pursuant to the terms hereof.

  SECTION 18. Termination of Security Interest.
 
  At any time after January 1, 1999, Pledgor may request the release of the
Pledged Collateral and the termination of the Collateral Agent's security
interest therein by delivering an officers' certificate from the Pledgor
certifying that (i) the Leverage Ratio (as such term is defined in the
Revolving Credit Agreement) is less than 3.50:1.00 as calculated at the end of
each fiscal quarter for the immediately preceding four consecutive fiscal
quarters, (ii) no Default or Event of Default exists or would exist immediately
before or after giving effect to such release, and (iii) all representations
and warranties made by the Credit Parties in the Revolving Loan Documents and
the Term Loan Documents are true and correct on the date of such certificate
immediately before or after giving effect thereto as though made on that date,
except to the extent such representations and warranties specifically related
to an earlier date, in which case they were true and correct on such earlier
date. Upon receipt by the Collateral Agent of evidence satisfactory to it that
the foregoing certifications are true, the Collateral Agent will, at Pledgor's
expense, execute and deliver to Pledgor such documents as Pledgor shall
reasonably request to evidence the termination of the security interest granted
hereby and Pledgor shall be entitled to the return, upon its request and at its
expense, against receipt and without recourse to Collateral Agent, of such of
the Pledged Collateral as shall not have been sold or otherwise applied
pursuant to the terms hereof. Upon such receipt by Pledgor of such remaining
Pledged Collateral, the security interest granted hereby shall terminate and
all rights to the Pledged Collateral shall revert to Pledgor.
 
  SECTION 19. Collateral Agent.
 
  (a) Collateral Agent has been appointed to act as Collateral Agent hereunder
pursuant to the Intercreditor Agreement by the Revolving Agent on behalf of the
Revolving Lenders, the Term Agent on behalf of the Term Lenders, each
Acknowledging Interest Rate Exchanger and each Acknowledging Currency
Exchanger, and shall be entitled to the benefits of the Intercreditor
Agreement. Collateral Agent shall be obligated, and shall have the right
hereunder, to make demands, to give notices, to exercise or refrain from
exercising any rights, and to take or refrain from taking any action
(including, without limitation, the release or substitution of Pledged
Collateral), solely in accordance with this Agreement, the Intercreditor
Agreement and the Financing Documents.
 
  (b) The Collateral Agent may resign or be removed and a successor Collateral
Agent may be appointed in the manner provided in the Intercreditor Agreement.
Resignation by the Collateral Agent pursuant to subsection 6(g) of the
Intercreditor Agreement shall also constitute notice of resignation as
Collateral Agent under this Agreement; removal of the Collateral Agent pursuant
to subsection 6(g) of the Intercreditor Agreement shall also constitute removal
as Collateral Agent under this Agreement; and appointment of a successor
Collateral Agent pursuant to subsection 6(g) of the Intercreditor Agreement
shall also constitute appointment of a successor Collateral Agent under this
Agreement. Upon the acceptance of any appointment as Collateral Agent under
subsection 6(g) of the Intercreditor Agreement by a successor Collateral Agent,
that successor Collateral Agent shall thereupon succeed to and become vested
with all the rights, powers, privileges and duties of the retiring or removed
Collateral Agent under this Agreement, and the retiring or removed Collateral
Agent under this Agreement shall promptly (i) transfer to such successor
Collateral Agent all sums, securities and other items of Collateral held
hereunder, together with all records and other documents necessary or
appropriate in connection with the performance of the duties of the successor
Collateral Agent under this Agreement, and (ii) execute and deliver to such
successor Collateral Agent such amendments to financing statements, and take
such other actions, as may be necessary or appropriate in connection with the
assignment to such successor Collateral Agent of the security interests created
hereunder, whereupon such retiring or removed Collateral Agent shall be
discharged from its duties and obligations under this Agreement. After any
retiring or removed Collateral Agent's resignation or removal hereunder as
Collateral Agent, the provisions of this Agreement shall inure to its benefit
as to any actions taken or omitted to be taken by it under this Agreement while
it was Collateral Agent hereunder.
 
  SECTION 20. Amendments; Etc. No amendment, modification, termination or
waiver of any provision of this Agreement, and no consent to any departure by
Pledgor therefrom, shall in any event be effective unless
 
                                       15

such party's name on the signature pages hereof or, as to either party, such
other address as shall be designated by such party in a written notice
delivered to the other party hereto.
 
  SECTION 22. Failure or Indulgence Not Waiver; Remedies Cumulative. No failure
or delay on the part of Collateral Agent in the exercise of any power, right or
privilege hereunder shall impair such power, right or privilege or be construed
to be a waiver of any default or acquiescence therein, nor shall any single or
partial exercise of any such power, right or privilege preclude any other or
further exercise thereof or of any other power, right or privilege. All rights
and remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.
 
  SECTION 23. Severability. In case any provision in or obligation under this
Agreement shall be invalid, illegal or unenforceable in any jurisdiction, the
validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction,
shall not in any way be affected or impaired thereby.
 
  SECTION 24. Headings. Section and subsection headings in this Agreement are
included herein for convenience of reference only and shall not constitute a
part of this Agreement for any other purpose or be given any substantive
effect.
 
  SECTION 25. Governing Law; Terms. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE

terms used in Articles 8 and 9 of the Uniform Commercial Code in the State of

to so serve, as its agent to receive on its behalf service of all process in
any such proceedings in any such court, such service being hereby acknowledged
by Pledgor to be effective and binding service in every respect. Nothing herein
shall affect the right to serve process in any other manner permitted by law or
shall limit the right of Collateral Agent to bring proceedings against Pledgor
in the courts of any other jurisdiction.
 
  SECTION 27. Waiver of Jury Trial. PLEDGOR AND COLLATERAL AGENT HEREBY WAIVE
THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED

be all-encompassing of any and all disputes that may be filed in any court and
that relate to the subject matter of this transaction, including without
limitation contract claims, tort claims, breach of duty claims, and all other
common law and statutory claims. Pledgor and Collateral Agent each acknowledge
that this waiver is a material inducement for Pledgor and Collateral Agent to
enter into a business relationship, that Pledgor and Collateral Agent have
already relied on this waiver in entering into this Agreement and that each
will continue to rely on this waiver in their related future dealings. Pledgor
and Collateral Agent further warrant and represent that each has reviewed this
waiver with its legal counsel, and that each knowingly and voluntarily waives
its jury trial rights following consultation with legal counsel. THIS WAIVER IS
IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING,
AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS
OR MODIFICATIONS TO THIS AGREEMENT. In the event of litigation, this Agreement
may be filed as a written consent to a trial by the court.

                       RATIO OF EARNINGS TO FIXED CHARGES
 
  The ratio of earnings to fixed charges is computed by dividing fixed charges
into earnings. Earnings is defined as pretax income from continuing operations
adjusted by adding fixed charges and excluding interest capitalized during the
period. Fixed charges means the total of interest expense and amortization of
financing costs, and the estimated interest component of rental expense on
operating leases. In 1995, we changed our fiscal year end to December 31 from
May 31.
