                                  THE COMPANY
 
  Total Renal Care Holdings, Inc. is the third largest provider of high-
quality dialysis and related services in the United States for patients
suffering from chronic kidney failure, also known as end stage renal disease
("ESRD"). As of the date of this Prospectus, the Company provides dialysis and
ancillary services to more than 12,900 patients through a network of 167
outpatient dialysis facilities in 17 states, as well as Washington, D.C., Guam
and the United Kingdom. In addition, the Company provides inpatient dialysis
services at 117 hospitals. The Company has implemented an aggressive growth
strategy since its recapitalization and change in ownership in August 1994,
adding 130 outpatient dialysis facilities to its network as well as 61
hospital inpatient contracts. 33 of the outpatient dialysis facilities and 30
of these hospital inpatient contracts have been added in the first six months
of 1997. The Company has also expanded its in-house ancillary services to
include ESRD laboratory and pharmacy facilities, as well as vascular access
management, transplant services programs and ESRD clinical research programs.
The increase in the number of facilities and hospital contracts, combined with
the enhancement of the Company's ancillary businesses, has resulted in an
increase in net operating revenues of 68.8% to $193.8 million in the six
months ended June 30, 1997 as compared to the same period in the previous
year. Since the Company's most recent equity offering in November 1996 the
Company has acquired 79 facilities servicing 3,300 patients, including 3
facilities servicing approximately 230 patients since July 1, 1997.
 
  The Company's growth strategy is focused on establishing strong regional
networks of clustered facilities that provide comprehensive care for ESRD
patients. The Company believes that this approach enhances its operating
efficiency and positions the Company to be a leader in a health care
environment increasingly influenced by managed care. The Company strives to
continue its growth and margin improvement by (i) expanding its existing
networks and by creating new regional facility networks through acquisitions,
the development of new facilities ("de novo" developments) and the formation
of hospital alliances, (ii) forming strategic alliances with physicians and
managed care organizations, (iii) expanding the range of ancillary services it
provides to patients, (iv) continuously improving the quality of care provided
through the Company's Quality Management Program and (v) maximizing operating
efficiencies and utilization. As part of the Company's growth strategy, it has
begun development of operations in various overseas markets.
 
RECENT EVENTS
 
  Six-Month Financial Results. Revenues increased 69% to $193.8 million in the
first six months of 1997 from $114.8 million in the corresponding period of
1996. Earnings increased 67% to $16.7 million, up from $10.0 million for the
corresponding period of 1996, and earnings per share increased 53% to $0.61 on
27.2 million weighted average shares outstanding for the six-month period
ended June 30, 1997, compared with earnings per share of $0.40 on 24.8 million
weighted average shares outstanding for the six-month period ended June 30,
1996.
 
  Acquisitions/New Programs. Since July 1, 1997, the Company has acquired 3
facilities servicing approximately 230 patients in separate transactions. The
Company has also signed definitive agreements to acquire facilities servicing
approximately 660 additional patients. In addition, the Company has entered
into 7 agreements in principle to acquire facilities servicing approximately
1,100 patients. Although there can be no assurance that the transactions will
be consummated, the Company currently expects that each transaction for which
a definitive agreement has been signed will close in the third quarter and the
balance over the remainder of the year.
 
  The Company recently acquired the Drug Evaluation Unit from the Minneapolis
Medical Research Foundation and thereby created Total Renal Pharmaceutical
Research, Inc. ("TRR"). TRR is a leading ESRD clinical research company
specializing in renal and renal-related studies. Headquartered in Minneapolis,
Minnesota, TRR has its core clinical site in the Hennepin County Medical
Center and plans to expand to multiple sites, initially throughout the U.S.
TRR conducts tolerance and pharmokinetics studies as well as Phase I through
IV clinical trials.
 
                                       3
<PAGE>
 
  The Company has recently committed to utilizing, system-wide and worldwide,
Health Outcomes Management Evaluation and Research ("HOMER") software from SSI
Health Systems, Inc. With its process-centered approach, HOMER relates
treatment parameters to patient problems, creating a versatile and powerful
outcomes database for clinical patient encounters. Management expects that
managed care reporting, outcomes analysis and risk assessment will be natural
extensions of HOMER.
 
  Credit Facilities. In August 1997, the Company entered into a commitment to
replace its $400 million bank credit facility with an aggregate of $1 billion
in two senior bank facilities (the "Senior Credit Facilities"). The Senior
Credit Facilities consist of a seven-year $800 million revolving credit
facility and a ten-year $200 million term facility. The Company has also
committed to enter into an additional forward interest swap agreement with a
notional amount of $200 million for a ten-year period beginning September 30,
1997. There can be no assurance that the Company will consummate the
transactions related to the Senior Credit Facilities or the swap agreement. See
"Underwriting."
 
  1997 Federal Budget. The Balanced Budget Act signed August 5, 1997 by
President Clinton included provisions: (1) providing for a permanent extension
to thirty months of the Medicare secondary payor requirement for items and
services furnished to ESRD patients by their existing Employer Group Health
Plan; and (2) specifying that where payment for drugs (other than EPO (defined
below)) is not made on a cost or prospective payment basis, the payment would
equal 95% of the Average Wholesale Price (as defined in federal laws and
regulations).
 
  The Company is a Delaware corporation. The Company's offices are located at
21250 Hawthorne Boulevard, Torrance, California 90503-5517 and its telephone
number is (310) 792-2600.

                                 RISK FACTORS
 
  In evaluating the Company and its business, prospective investors should
carefully consider the following risk factors in addition to the other
information contained herein. This Prospectus and the materials incorporated
herein by reference contain statements that constitute "forward-looking"
statements within the meaning of the Private Securities Litigation Reform Act
of 1995. Such forward-looking statements relate to future events or the future
financial performance of the Company and involve known and unknown risks,
uncertainties and other factors that may cause the actual results, performance
or achievements of the Company to be materially different from any future
results, performance or achievements expressed or implied by such forward-
looking statements. Such factors include, among other things, those discussed
below, and such factors could cause actual results to differ materially from
those indicated by such forward-looking statements. The Company undertakes no
obligation to publicly update or revise any forward-looking statements,
whether as a result of new information, future events or otherwise. In light
of these risks and uncertainties, there can be no assurance that the forward-
looking information contained in this Prospectus or the materials incorporated
herein by reference will in fact transpire.
 
DEPENDENCE ON MEDICARE, MEDICAID AND OTHER SOURCES OF REIMBURSEMENT
 
  The Company is reimbursed for dialysis services primarily at fixed rates
established in advance under the Medicare End Stage Renal Disease program.
Under this program, once a patient becomes eligible for Medicare
reimbursement, Medicare is responsible for payment of 80% of the composite
rates determined by the Health Care Financing Administration ("HCFA") for
dialysis treatments. Since 1972, qualified patients suffering from ESRD have
been entitled to Medicare benefits regardless of age or financial
circumstances. The Company estimates that approximately 61% of its net patient
revenues during its fiscal year ended December 31, 1996, and approximately 59%
during the six months ended June 30, 1997 were funded by Medicare. Since 1983,
numerous Congressional actions have resulted in changes in 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. The Company is not able to predict
whether future rate changes will be made. Reductions in composite rates could
have a material adverse effect on the Company's revenues and net earnings.
Furthermore, increases in operating costs that are subject to inflation, such
as labor and supply costs, without a compensating increase in prescribed
rates, may adversely affect the Company's earnings in the future. The Company
is also unable to predict whether certain services, as to which the Company is
currently separately reimbursed, may in the future be included in the Medicare
composite rate.
 
  Since June 1, 1989, the Medicare ESRD program has provided reimbursement for
the administration to dialysis patients of erythropoietin ("EPO"). EPO is
beneficial in the treatment of anemia, a medical complication frequently
experienced by dialysis patients. Many of the Company's dialysis patients
receive EPO. Revenues from EPO (the substantial majority of which are
reimbursed through Medicare and Medicaid programs) were approximately $55.1
million, or 20% of net patient revenues, in its fiscal year ended December 31,
1996, and were $38.9 million, or 20% of net patient revenues, during the six
months ended June 30, 1997. EPO reimbursement significantly affects the
Company's net income. Medicare reimbursement for EPO was reduced from $11 to
$10 per 1,000 units for services rendered after December 31, 1993. EPO is
produced by a single manufacturer, and any interruption of supply or product
cost increases could adversely affect the Company's operations. Prices paid
for EPO by the Company, its public competitors, and other dialysis providers
are presently the subject of a pricing survey being conducted on behalf of
HCFA.
 
  All of the states in which the Company currently operates dialysis
facilities provide Medicaid (or comparable) benefits to qualified recipients
to supplement their Medicare entitlement. The Company estimates that
approximately 6% of its net patient revenues during the fiscal year ended
December 31, 1996 and 8% of its net patient revenues during the six month
period ended June 30, 1997 were funded by Medicaid or comparable state
programs. The Medicaid programs are subject to statutory and regulatory
changes, administrative rulings, interpretations of policy and governmental
funding restrictions, all of which may have the effect of decreasing program
payments, increasing costs or modifying the way the Company operates its
dialysis business.
 
                                       5
<PAGE>
 
  Approximately 33% of the Company's net patient revenues during the fiscal
year ended December 31, 1996, and 33% of the Company's net patient revenues
during the six months ended June 30, 1997 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, and payments from hospitals with which the Company has contracts for
the provision of acute dialysis treatments. Any restriction or reduction of
the Company's ability to charge for such services at rates in excess of those
paid by Medicare would adversely affect the Company's net operating revenues
and net income. The Company is unable to quantify or predict the degree, if
any, of the risk of reductions in payments under these various payment plans.
The Company is a party to non-exclusive agreements with certain third-party
payors and termination of such third-party agreements could have an adverse
effect on the Company.
 
OPERATIONS SUBJECT TO GOVERNMENT REGULATION
 
  The Company is subject to extensive regulation by both the federal
government and the states in which the Company conducts its business. The
Company is subject to the illegal remuneration provisions of the Social
Security Act and similar state laws, which impose civil and criminal sanctions
on persons who solicit, offer, receive or pay any remuneration, directly or
indirectly, for referring a patient for treatment that is paid for in whole or
in part by Medicare, Medicaid or similar state programs. In July 1991 and
November 1992, the federal government published regulations that provide
exceptions or "safe harbors" for certain business transactions. Transactions
that are structured within the safe harbors are deemed not to violate the
illegal remuneration provisions. Transactions that do not satisfy all elements
of a relevant safe harbor do not necessarily violate the illegal remuneration
statute, but may be subject to greater scrutiny by enforcement agencies.
Neither the arrangements between the Company and the physician directors of
its facilities ("Medical Directors") nor the minority ownership interests of
referring physicians in certain of the Company's dialysis facilities meet all
of the necessary requirements to obtain full protection afforded by these safe
harbors. Although the Company has never been challenged under these statutes
and believes it complies in all material respects with these and all other
applicable laws and regulations, there can be no assurance that the Company
will not be required to change its practices or relationships with its Medical
Directors or with referring physicians holding minority ownership interests or
that the Company will not experience material adverse effects as a result of
any such challenge.
 
  The Omnibus Budget Reconciliation Act of 1989 includes certain provisions
("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." In August 1995, HCFA published regulations
interpreting Stark I. The regulations specifically provide that services
furnished in an ESRD facility that are included in the composite billing rate
are excluded from the coverage of Stark I. The Company believes that the
language and legislative history of Stark I indicate that Congress did not
intend to include laboratory services provided incidental to dialysis services
within the Stark I prohibition; however, laboratory services not included in
the Medicare composite rate could be included within the coverage of Stark I.
Violations of Stark I are punishable by civil penalties which may include
exclusion or suspension of a provider from future participation in Medicare
and Medicaid programs and substantial fines. Due to the breadth of the
statutory provisions, it is possible that the Company's practices might be
challenged under this law. A broad interpretation of Stark I would apply to
the Company's competitors as well.
 
  The Omnibus Budget Reconciliation Act of 1993 includes certain provisions
("Stark II") that restrict physician referrals for certain "designated health
services" to entities with which a physician or an immediate family member has
a "financial relationship." The Company believes that the language and
legislative history of Stark II indicate that Congress did not intend to
include dialysis services and the services and items provided incident to
dialysis services within the Stark II prohibitions; however, certain services,
including the provision of, or arrangement and assumption of financial
responsibility for, outpatient prescription drugs, including EPO, and clinical
laboratory services, could be construed as designated health services within
the meaning of Stark II. Violations of 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.
Due to the breadth of the statutory provisions and the absence of regulations
or court decisions addressing the specific arrangements
 
                                       6
<PAGE>
 
by which the Company conducts its business, it is possible that the Company's
practices might be challenged under these laws. A broad interpretation of
Stark II to include dialysis services and items provided incident to dialysis
services would apply to the Company's competitors as well.
 
  A California statute that became effective January 1, 1995 makes it unlawful
for a physician who has, or a member of whose immediate family has, a
financial interest with or in an entity to refer a person to that entity for,
among other services, laboratory services. The Company currently operates
centers in California, which account for a significant percentage of net
operating revenues. Although the Company does not believe that the statute is
intended to apply to laboratory services that are provided incident to
dialysis services, it is possible that the statute could be interpreted to
apply to such laboratory services. If the California statute were so
interpreted, the Company would be required to restructure some or all of its
relationships with referring physicians who serve as Medical Directors of the
Company's facilities and with the physicians who hold minority interests in
certain of the Company's facilities. The Company also operates dialysis
facilities and provides laboratory services in Virginia, Georgia, Florida,
Illinois, Minnesota, Maryland, Michigan, New York and Puerto Rico all of which
have so-called "fraud and abuse" statutes which regulate the Company's
relationships with physicians.
 
  At present, ESRD patients eligible for California's Medicaid program,
MediCal, are reimbursed for their transportation costs relating to ESRD
treatments. If this practice is deemed to violate applicable federal or state
law, the Company may be forced to halt this practice and the Company cannot
predict the effect the foregoing would have on the desire of such patients to
use the Company's services.
 
  The Company's two licensed clinical laboratories are also subject to
extensive federal and state regulation of performance standards, including the
provisions of The Clinical Laboratory Improvement Act of 1967 and The Clinical
Laboratory Improvement Amendments of 1988 Act, as well as the federal and
state regulations described above. The Company's laboratory subsidiary is
presently the subject of a third-party carrier review and a State of Florida
Medicaid review. The reviewing entities have requested medical and billing
records for certain patients, and the Company has provided the requested
records. Neither the third-party carrier nor Florida Medicaid has informed the
Company of the reason for or the nature or scope of its review.
 
  A number of proposals for health care reform have been made in recent years,
some of which have included radical changes in the health care system. Health
care reform could result in material changes in the financing and regulation
of the health care business, and the Company is unable to predict the effect
of such changes on its future operations. It is uncertain what legislation on
health care reform, if any, will ultimately be implemented or whether other
changes in the administration or interpretation of governmental health care
programs will occur. There can be no assurance that future health care
legislation or other changes in the administration or interpretation of
governmental health care programs will not have a material adverse effect on
the results of operations of the Company.
 
RISKS INHERENT IN GROWTH STRATEGY
 
  Beginning after the recapitalization in August 1994, which effected a change
in ownership, the Company has had an aggressive growth strategy. This growth
strategy is dependent on the continued availability of suitable acquisition
candidates and subjects the Company to the risks inherent in assessing the
value, strengths and weaknesses of acquisition candidates, the operations of
acquired companies and identifying suitable locations for additional
facilities. The Company's growth is expected to place significant demands on
the Company's financial and management resources. In recent years, acquisition
prices and competition for facilities has increased. To the extent the Company
is unable to acquire or develop facilities in a cost-effective manner, its
ability to expand its business and enhance results of operations would be
adversely affected. In addition, although the Company believes it has a
demonstrable track record of integrating the operations of acquired companies
with its historic operations, the process for integrating acquired operations,
particularly for newly acquired regional clusters, presents a significant
challenge to the Company's management and may lead to unanticipated costs or a
diversion of management's attention from day-to-day operations. There can be
no assurance that the Company will be able to continue its growth strategy or
that this strategy will ultimately prove successful. A failure to successfully
continue its growth strategy could have an adverse effect on the Company's
results of operations.

COMPETITION
 
  The dialysis industry is fragmented and highly competitive, particularly in
terms of acquisitions of existing dialysis facilities and developing
relationships with referring physicians. Certain of the Company's competitors
have substantially greater financial resources than the Company and may
compete with the Company for acquisitions of facilities in markets targeted by
the Company. Competition for acquisitions has increased the cost of acquiring
existing dialysis facilities. The Company has from time to time experienced
competition from referring physicians who have opened their own dialysis
facilities. A portion of the Company's 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, the Company could be adversely affected.
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company is dependent upon the services and management experience of the
Company's executive officers, and accordingly has entered into employment
agreements with, and provided a variety of equity incentives to, each of these
executives. The Company's continued growth depends upon its ability to attract
and retain skilled employees, in particular highly skilled nurses, for whom
competition is intense. The Company believes that its future success will also
be significantly dependent on its ability to attract and retain qualified
physicians to serve as Medical Directors of its dialysis facilities. The
Company does not carry key-man life insurance on any of its officers.
 
DEPENDENCE ON PHYSICIAN REFERRALS
 
  The Company's facilities are dependent upon referrals of ESRD patients for
treatment by physicians specializing in nephrology and practicing in the
communities served by the Company's dialysis facilities. As is generally true
in the dialysis industry, at each facility one or a few physicians account for
all or a significant portion of the patient referral base. 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
the Company's overall operations. Referring physicians own minority interests
in certain of the Company's dialysis facilities. If such interests are deemed
to violate applicable federal or state law, such physicians may be forced to
dispose of their ownership interests. The Company cannot predict the effect
such dispositions would have on its business. See "--Operations Subject to
Government Regulation."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
  The trading price and volume of the Common Stock historically has been and
could in the future be subject to significant fluctuations in response to many
factors, including quarter-to-quarter variations in operating results, changes
in earnings estimates by analysts, changes in federal or state regulation of
services provided by the Company or reimbursement rates for such services,
competition, general market conditions and other events or factors.
 
ANTITAKEOVER PROVISIONS
 
  The Company's Certificate of Incorporation and Bylaws include several
provisions which may have the effect of deterring hostile takeovers, delaying
or preventing changes in control or changes in management of the Company, or
limiting the ability of stockholders to approve transactions that they may
deem to be in their best interests, including (i) a provision requiring that
any action required or permitted to be taken by stockholders of the Company
must be effected at a duly called annual or special meeting of stockholders
and may not be effected by written consent, and (ii) 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. In addition, pursuant to the Company's Certificate of
Incorporation the Board of Directors has the authority to issue up to
5,000,000 shares of Preferred Stock and to determine the rights and
preferences of such Preferred Stock without the need for further stockholder
approval. The Company has no present plans to issue any shares of Preferred
Stock.

SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
  Substantially all of the shares of Common Stock that are outstanding are
available for immediate sale in the public market (subject to certain resale
limitations under Rule 144 of the Securities Act). Sales of substantial
amounts of Common Stock into the public market or the perception that such
sales could occur, could adversely affect the prevailing market price for the
Common Stock and the ability of the Company to raise equity capital. The
Company can make no prediction as to the effect, if any, that sales of shares
of its Common Stock, or the availability of shares for future sale, will have
on the market price of the Common Stock prevailing from time to time. Such
sales may also make it more difficult for the Company to sell equity
securities or equity-related securities at a time and price that it deems
appropriate. Certain stockholders of the Company are also entitled to
registration rights. See "Selling Stockholders."

(1) In 1995, the Company changed its fiscal year end to December 31 from May
    31.
(2) The organization of the holding company and sale of approximately 75% of
    the Company in August 1994 by Tenet to DLJMBP and certain of its
    affiliates, management of the Company and certain holders of debt
    securities of the Company (the "August 1994 Transaction") and subsequent
    acquisitions had a significant impact on the Company's capitalization and
    equity securities and on the Company's results of operations.
    Consequently, the Balance Sheet Data as of May 31, 1995, as of December
    31, 1995 and 1996 and as of June 30, 1997 and the Income Statement Data
    for the fiscal year ended May 31, 1995, for the seven months ended
    December 31, 1995, the year ended December 31, 1996 and the six month
    periods ended June 30, 1996 and 1997 are not directly comparable to
    corresponding information as of prior dates and for prior periods,
    respectively.
(3) General and administrative expenses for the fiscal years ended May 31,
    1992, 1993 and 1994 include overhead allocations by the Company's former
    parent of $662,000, $235,000 and $1,458,000, respectively. The overhead
    allocations for the fiscal years ended May 31, 1992 and 1993 were made
    using a different methodology than that used in the fiscal year ended May
    31, 1994 and the substantial increase in that year reflects this change in
    methodology rather than a change in the level of services provided. No
    overhead allocation was made for the period from March 1, 1994 through the
    closing of the August 1994 Transaction, at which time the Company 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 reflect $458,000 in expenses relating to a terminated equity
    offering.
(4) In December 1995, the Company recorded an extraordinary loss of
    $2,555,000, or $0.14 per share, net of tax, on the early extinguishment of
    debt. In July and September 1996, the Company recorded a combined
    extraordinary loss of $7,700,000 or $0.30 per share, net of tax, on the
    early retirement of the remaining outstanding Senior Subordinated Discount
    Notes.
(5) Income per share before extraordinary item for the year ended May 31, 1995
    and for the seven months ended December 31, 1994 is presented on a pro
    forma basis to give effect to the August 1994 Transaction as if it had
    occurred on June 1, 1994.
(6) Represents dialysis treatments provided in outpatient facilities, at home
    and in acute care hospitals. Home dialysis treatments are stated in
    hemodialysis equivalents. Only treatments rendered by the Company after
    the acquisition of a facility are included.
(7) Mandatorily redeemable Common Stock represents shares of Common Stock
    issued in certain acquisitions subject to put options that terminated upon
    the completion of its initial public offering of Common Stock in October
    1995.
(8) In connection with the August 1994 Transaction, the Company paid a
    dividend to Tenet of $75.5 million.

                         DESCRIPTION OF CAPITAL STOCK
 
  The following summary is a description of certain provisions of the
Company's Certificate of Incorporation, as amended and restated (the
"Certificate of Incorporation"). Such summary does not purport to be complete
and is subject to, and is qualified in its entirety by, all of the provisions
of the Certificate of Incorporation.
 
  The Company's authorized capital stock consists of 55,000,000 shares of
Common Stock, $0.001 par value, and 5,000,000 shares of Preferred Stock,
$0.001 par value ("Preferred Stock").
 
COMMON STOCK
 
  As of August 1, 1997, there were 26,662,657 shares of Common Stock issued
and outstanding. The Company does not anticipate paying any cash dividends on
the Common Stock in the foreseeable future. The Company is subject to certain
restrictions on its ability to pay dividends on the Common Stock under the
Senior Credit Facility.
 
  Holders of Common Stock are entitled to one vote for each share held of
record on all matters submitted to a vote of stockholders. There are no
cumulative voting rights applicable to the Common Stock.
 
  Subject to the preferences applicable to shares of Preferred Stock
outstanding at any time, holders of shares of Common Stock are entitled to
dividends, if, when and as declared by the Board of Directors from funds
legally available therefor and are entitled, in the event of liquidation, to
share ratably in all assets remaining after payment of liabilities and
preferred stock preferences, if any.
 
  The authorized but unissued shares of Common Stock are available for
issuance without further action by the Company's stockholders, unless such
action is required by applicable law or the rules of any stock exchange on
which the Common Stock may be listed. Shares of Common Stock are not
redeemable and there are no sinking fund provisions.
 
PREFERRED STOCK
 
  The Certificate of Incorporation authorizes the Company's Board of Directors
to establish series of Preferred Stock and to determine, with respect to any
series of Preferred Stock, the voting powers, or no voting powers, and such
designations, preferences and relative, participating, optional or other
special rights and such qualifications, limitations or restrictions thereof,
as are stated in the resolutions of the Board of Directors providing for such
series.
 
  The authorized but unissued shares of Preferred Stock are available for
issuance without further action by the Company's stockholders. This will allow
the Company to issue shares of Preferred Stock without the expense and delay
of a special stockholders' meeting, unless such action is required by
applicable law or the rules of any stock exchange on which the Company's
securities may be listed. The Company believes that the Preferred Stock will
provide flexibility in structuring possible future financing and acquisitions,
and in meeting other corporate needs. Although the Company's Board of
Directors has no intention at the present time of doing so, it could issue a
series of Preferred Stock, the terms of which, subject to certain limitations
imposed by the securities laws, impede the completion of a merger, tender
offer or other takeover attempt. The Company's Board of Directors will make
any determination to issue such shares based on its judgment as to the best
interests of the Company and its stockholders at the time of issuance. The
Company's Board of Directors, in so acting, could issue Preferred Stock having
terms that could discourage an acquisition attempt or other transaction that
some, or a majority, of the stockholders might believe to be in their best
interests or in which stockholders might receive a premium for their stock
over the then market price of such stock.
 
TRANSFER AGENT
 
  The Company's registrar and transfer agent for the Common Stock is The Bank
of New York.

                                 UNDERWRITING
 
  Subject to the terms and conditions contained in the Underwriting Agreement
(the "Underwriting Agreement"), DLJ (the "Underwriter") has agreed to purchase
from the Selling Stockholders an aggregate of 2,595,524 shares of Common
Stock.
 
  The Underwriting Agreement provides that the obligations of the Underwriter
to accept delivery of the shares of Common Stock offered hereby are subject to
approval of certain legal matters by counsel and to certain other conditions.
If any shares of Common Stock are purchased by the Underwriter pursuant to the
Underwriting Agreement, all such shares must be purchased.
 
  The Underwriter has advised the Selling Stockholders that it proposes to
offer the shares of Common Stock in part directly to the public initially at
the Price to the Public set forth on the cover page of this Prospectus and in
part to certain dealers at such price less a concession not in excess of $
per share; that the Underwriter may allow, and such dealers may reallow, a
concession not in excess of $   per share on sales to other dealers; and that
after this offering, the Price to the Public, concession and discount to
dealers may be changed by the Underwriter.
 
  The Company and the Selling Stockholders have agreed to indemnify the
Underwriter against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments that the Underwriter may be
required to make in respect thereof.
 
  Subject to certain exceptions (including certain issuances by the Company of
Common Stock in connection with acquisitions), the Company, all of its
executive officers and directors and certain stockholders of the Company each
have agreed not to, directly or indirectly, offer, sell, contract to sell,
grant any option to purchase or otherwise dispose of any Common Stock or any
securities convertible into or exercisable or exchangeable for such Common
Stock or cause to be filed with the Securities and Exchange Commission a
registration statement under the Securities Act to register any shares of the
Common Stock or, in any manner, transfer all or a portion of the economic
consequences associated with the ownership of the Common Stock without the
prior written consent of DLJ for a period of 90 days after the date of this
Prospectus.
 
  The provisions of Rule 2720 of the Conduct Rules of the National Association
of Securities Dealers, Inc. (the "NASD") apply to this offering. Under such
rules, when a NASD member such as DLJ distributes an affiliated company's
equity securities, one of the following two criteria must be met: (1) the
price of such equity security can be no higher than that recommended by a
"qualified independent underwriter" or (2) the offering is of a class of
equity securities for which a "bona fide independent market" exists. See
"Selling Stockholders." Because the shares of Common Stock are traded on the
New York Stock Exchange, the aggregate trading volume for the twelve months
immediately preceding the filing of the registration statement of which this
Prospectus forms a part was at least 100,000 shares and the Company had
outstanding for the twelve month period immediately preceding the filing of
such registration statement a minimum of 250,000 publicly held shares, a "bona
fide independent market" exists. Accordingly, the price of the Common Stock
will not be passed upon by a "qualified independent underwriter."
 
  Pursuant to the provisions of Rule 2720 of the Conduct Rules, NASD members
may not execute transactions in the shares of Common Stock offered hereby in
discretionary accounts without the prior written approval of the customer.
 
  DLJ and certain of its affiliates from time to time perform various
investment banking and other services for the Company, for which the Company
pays customary consideration. See "Selling Stockholders." An affiliate of DLJ
is presently a participant in and/or co-lead agent for certain of the
Company's bank financing arrangements, for which it received customary
consideration, and expects to do so in connection with certain proposed
refinancings thereof. See "The Company."
 
  In connection with this offering, the Underwriter may engage in transactions
that stabilize, maintain or otherwise affect the price of the Common Stock.
Specifically, the Underwriter may bid for and purchase shares
 
                                      14
<PAGE>
 
of Common Stock in the open market to stabilize the price of the Common Stock.
These activities may stabilize or maintain the price of the Common Stock.
These activities may stabilize or maintain the price of the Common
Stock above independent market levels. The Underwriter is not required to
engage in these activities, and may end these activities at any time.
 
                                 LEGAL MATTERS
 
  Certain legal matters with respect to the legality of the Shares offered
hereby will be passed upon for the Company by Barry C. Cosgrove, General
Counsel of the Company. Certain legal matters will be passed upon for the
Underwriter by Skadden, Arps, Slate, Meagher & Flom LLP, Los Angeles,
California.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 of the Delaware Corporation Law provides that a Delaware
corporation may indemnify any person against expenses, judgments, fines and
settlements actually and reasonably incurred by any such person in connection
with a threatened, pending or completed action, suit or proceeding in which he
is involved by reason of the fact that he is or was director, officer,
employee or agent of such corporation, provided that (i) he acted in good
faith and in a manner reasonably believed to be in or not opposed to the best
interests of the corporation and (ii) with respect to any criminal action or
proceeding, he had no reasonable cause to believe his conduct was unlawful. If
the action or suit is by or in the name of the corporation, the corporation
may indemnify any such person against expense actually and reasonably incurred
by him in connection with the defense or settlement of such action or suit if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation, except that no
indemnification may be made in respect to any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation for
negligence or misconduct in the performance of his duty to the corporation,
unless and only to the extent that the Delaware Court of Chancery or the court
in which the action or suit is brought determines upon application that,
despite the adjudication of liability but in view of all of the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for
such expense as the court deems proper.
 
  Article XI, Section 1 of the Company's By-Laws provides for indemnification
of its directors and officers to the fullest extent permitted by the Delaware
Corporation Law. In accordance with the Delaware Corporation Law, the
Company's Certificate of Incorporation, as amended, limits the personal
liability of its directors for violations of their fiduciary duty. The
Certificate of Incorporation eliminates each director's liability to the
Company or its stockholders for monetary damages except (i) for any breach of
the director's duty of loyalty to the Company or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, (iii) under the section of the Delaware law
providing for liability of directors for unlawful payment of dividends or
unlawful stock purchases or redemptions, or (iv) for any transaction from
which a director derived any improper personal benefit. The effect of this
provision is to eliminate the personal liability of directors for monetary
damages for actions involving a breach of their fiduciary duty of care,
including any such actions involving gross negligence.
 
  This provision will not, however, limit in any way the liability of
directors for violations of the Federal officers to indemnify them to the
maximum extent permitted by Delaware law.
 
  The form of Underwriting Agreement, filed as Exhibit 1 hereto, provides for
the indemnification of the Company, its control persons, its directors and
certain of its officers by the Underwriters against certain liabilities,
including liabilities under the Securities Act.

    (iii) To include any material information with respect to the plan of
  distribution not previously disclosed in the registration statement or any
  material change to such information in the registration statement.
 
Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Securities and Exchange Commission by the registrant pursuant to Section 13 or
Section 15(d) of the Exchange Act that are incorporated by reference in the
registration statement.
 
  (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
  (3) To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.
 
  (4) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
  (5) To deliver or cause to be delivered with the prospectus, to each person
to whom the prospectus is sent or given, the latest annual report to security
holders that is incorporated by reference in the prospectus and furnished
pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the
Exchange Act.
 
  (6) That for purposes of determining any liability under the Securities Act,
the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in the form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective; and

  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

its properties as described in the Registration Statement and Prospectus, and
each corporate Subsidiary is duly qualified and is in good standing as a foreign
corporation and each Subsidiary is authorized to do business in each
jurisdiction in which the nature of its business or its ownership or leasing of
property requires such qualification or authorization, except here the failure
to be so qualified and be in good standing could not, in the aggregate,
reasonably be expected to have a material adverse effect on the business,
operations, properties, or financial or other condition of the Company and its
Subsidiaries, considered as a whole.

          (f) Except as disclosed in the Prospectus, (i) all of the outstanding
shares of capital stock of each the Company's corporate Subsidiaries have been
duly authorized and validly issued and are fully paid and non-assessable and, in
the case of Total Renal Care, Inc., a California corporation ("TRC"), are wholly

free and clear of any security interest, claim, lien, encumbrance or adverse
interest of any nature ("Liens") and (ii) all of the outstanding partnership
interests in each of the Company's partnership Subsidiaries have been duly
authorized by its respective partnership agreement and validly issued and the
partnership interests in such partnerships that are not owned by unaffiliated
third parties are owned directly or indirectly by the Company, free and clear of
any Liens, and any partnership capital contribution obligations of 

                                       11
<PAGE>
 
the Company in each partnership Subsidiary have been satisfied.

          (g) All the outstanding shares of capital stock of the Company

fully paid, non-assessable and not subject to any preemptive or similar rights.

          (h) The authorized capital stock of the Company, including the Common

          (i) Neither the Company nor any of its Subsidiaries is in violation of

in default in any material respect, and no condition exists that with notice or
lapse of time or both would  constitute a material default in the performance of
any material obligation, agreement or condition contained in  any bond,
debenture, note or any other evidence of indebtedness or in any other material
agreement, indenture or instrument to which the Company or any of its
Subsidiaries is a party or by which it or any of is Subsidiaries or their
respective property is bound except to the extent such violation or default, if
any, could not reasonably be expected to have a material adverse effect on the
business, operations, properties or financial or other condition of the Company
and its Subsidiaries, considered as a whole.

          (j) The execution, delivery and performance of this Agreement,
compliance by the Company with all the provisions hereof and the consummation of
the transactions contemplated hereby will not require any  consent, approval,
authorization or other order of any court, regulatory body, administrative 
agency or other governmental body (except as such may be required under the
securities or Blue Sky laws of the various states) and will not conflict with or
constitute a breach of any 

                                       12
<PAGE>
 
of the terms or provisions of, or a default under, the charter or by-laws of the
Company or any of its subsidiaries or any agreement, indenture or other
instrument to which it or any of its subsidiaries is party or by which it or any
of its subsidiaries or their respective property is bound, or violate or
conflict with any laws, administrative regulations or rulings or court decrees
applicable to the Company, any of its subsidiaries or their respective property.

          (k) Except as otherwise set forth in the Prospectus, there are no
material legal or governmental  proceedings pending to which the Company or any
of its subsidiaries is a party or of which any of their respective property is
the subject, and, to the best of the Company's knowledge, no such proceedings
are threatened or contemplated.  No contract or document of a character required
to be described in the Registration Statement or the Prospectus or to be filed
as an exhibit to the Registration Statement is not so described or filed as
required.

          (l) Neither the Company nor any of its  subsidiaries has violated any
foreign, federal, state or  local law or regulation relating to the protection
of human health and safety, the environment or hazardous or toxic substances or
wastes, pollutants or contaminants ("Environmental Laws"), nor any federal or
state law relating to discrimination in the hiring, promotion or pay of
employees nor any applicable federal or state wages and hours laws, nor any
provisions of the Employee Retirement Income Security Act or the rules and
regulations promulgated thereunder, which in each case might result in any
material adverse change in the business, prospects, financial condition or
results of operation of the Company and its subsidiaries, taken as a whole.

          (m) The Company and each of its subsidiaries has such permits,
licenses, franchises and authorizations of governmental or regulatory
authorities ("permits") including, without limitation, under any applicable
Environmental Laws, as are necessary to own, lease and operate its respective
properties and to conduct its business; the Company and each of its subsidiaries
has fulfilled and performed all of its material obligations with respect to such
permits and no event has occurred which allows, or after notice or lapse of time

                                       13
<PAGE>
 
would allow, revocation or termination thereof or results in any other material
impairment of the rights of the holder of any such permit; and, except as
described in the Prospectus, such permits contain no restrictions that are
materially burdensome to the Company or any of its subsidiaries.

          (n) In the ordinary course of its business, the Company conducts a
periodic review of the effect of Environmental Laws on the business, operations
and properties of the Company and its subsidiaries, in the course of which it
identifies and evaluates associated costs and liabilities (including, without
limitation, any capital or operating expenditures required for clean-up, closure
of properties or compliance with Environmental Laws or any permit, license or
approval, any related constraints on operating activities and any potential
liabilities to third parties).  On the basis of such review, the Company has
reasonably concluded that such associated costs and liabilities would not,
singly or in the aggregate, have a material adverse effect on the Company and
its subsidiaries, taken as a whole.

          (o) Except as otherwise set forth in the prospectus or such as are not
material to the business, prospectus, financial condition or results of
operation  of the Company and its Subsidiaries, taken as a whole, the Company
and each of its Subsidiaries has good and marketable title, free and clear of
all Liens, claims, encumbrances and restrictions except Liens for taxes not yet
due and payable, to all property and assets described in the Registration
Statement as being owned by it.  All leases to which the Company or any of its
subsidiaries is a party are valid and binding and no default has occurred or is
continuing thereunder, which might result in any material adverse change in the
business, prospects, financial condition or results of operation of the Company
and its Subsidiaries taken as a whole, and the Company and its Subsidiaries
enjoy a peaceful and undisturbed possession under all such leases to which any
of them is a party as lessee with such exceptions as do not materially interfere
with the use made by the Company or such Subsidiary.

          (p) The Company and each of its Subsidiaries maintains reasonably
adequate insurance.

1994 and 1993, KPMG Peat Marwick, LLP was, an independent public accountant with
respect to the Company as required by the Act.

          (r) The financial statements, together with related schedules and

Prospectus, subject to such qualifications as may be set forth in the
Prospectus; the Company and each of its Subsidiaries has fulfilled and performed

may be set forth in the Prospectus; and, except as described in the Prospectus,
such permits contain no restrictions that are materially burdensome to the
Company or any of its Subsidiaries.

waived.

ment") and to sell, assign, transfer and deliver which Shares in the manner
provided herein and therein, and this Agreement and the Custody Agreement, if
any, have been duly authorized, executed and delivered by such Selling
Stockholder and each of this Agreement and the Custody Agreement is a valid and
binding agreement such Selling Stockholder enforceable in accordance with its
terms, except as rights to indemnity and contribution hereunder may be limited
by applicable law.

          (d) The power of attorney signed by such Selling Stockholder
appointing Leonard W. Frie, Barry C. Cosgrove and John E. King, or any one of
them, as his attorney-in-fact to the extent set forth therein with regard to the
transactions contemplated hereby and by the Registration Statement and the
Custody Agreement, if any, has been duly authorized, executed and delivered by
or on behalf of such Selling Stockholder and is a valid and binding instrument
of such Selling Stockholder enforceable in accordance with its terms, and,
pursuant to such power of attorney, such Selling Stockholder has authorized
Leonard W. Frie, Barry C. Cosgrove and John. E. King, or any one of them, to
execute and deliver on his behalf this Agreement and any other document
necessary or desirable in connection with transactions contemplated hereby and
to deliver the Shares to be sold by such Selling Stockholder pursuant to this

          (e) Such Selling Stockholder has not taken, and will not take,
directly or indirectly, any action designed to, or which might reasonably be

          (f) The execution, delivery and performance of this Agreement by such
Selling Stockholder, compliance by such Selling Stockholder with all the
provisions thereof and the consummation of the transactions contemplated hereby

<PAGE>
 
mental body (except as such may be required under the Act, state securities laws
or Blue Sky laws) and will not conflict with or constitute a breach of any of
the terms or provisions of, or a default under, organizational documents of such
Selling Stockholder, if not an individual, or any agreement, indenture or other
instrument to which such Selling Stockholder is a party or by which such Selling
Stockholder or property of such Selling Stockholder is bound, or violate or
conflict with any laws, administrative regulation or ruling or court decree
applicable to such Selling Stockholder or property of such Selling Stockholder.

          (g) Such parts of the Registration Statement under the caption

          ---------------                                                 
harmless the Underwriter and each person, if any, who controls the Underwriter
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act,
from and against any and all losses, claims, damages, liabilities and judgments
caused by any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement or the Prospectus (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) or any preliminary prospectus, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or judgments are caused by any such untrue
statement or omission or alleged untrue statement or omission based upon
information relating to the Under-

                                       18
<PAGE>
 
writer furnished in writing to the Company by the Underwriter expressly for use
therein.

          (b) The Selling Stockholders hereby severally and not jointly agree
to indemnify and hold harmless the Underwriter and each person, if any, who
controls the Underwriter within the meaning of Section 15 of the Act or Section
20 of the Exchange Act, from and against any and all losses, claims, damages,
liabilities and judgments caused by any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement or the
Prospectus (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto) or any preliminary prospectus, or caused by
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading; 
provided, however, that such agreement of each Selling Stockholder to indemnify
- --------  -------           
and hold harmless shall be limited to losses, claims, damages, liabilities or
judgments caused by any untrue statement or omission or alleged untrue statement
or omission based upon information furnished in writing to the Company by or on
behalf of such Selling Stockholder expressly for use in the Registration 
Statement; provided, further, that the aggregate liability of any Selling 
           --------  ------- 
Stockholder pursuant to the provisions of this paragraph shall be limited to an
amount equal to the aggregate purchase price received by such Selling
Stockholder from the sale of such Selling Stockholder's Shares hereunder.

          (c) In case any action shall be brought against the Underwriter or any
person controlling the Underwriter, based upon any preliminary prospectus, the
Registration Statement or the Prospectus or any amendment or supplement thereto
and with respect to which indemnity may be sought against the Company or the
Selling Stockholders, the Underwriter shall promptly notify the Company and the
Selling Stockholders in writing and the Company and/or the Selling Stockholders
shall assume the defense thereof, including the employment of counsel reasonably
satisfactory to such indemnified party and payment of all fees and expenses.
The Underwriter or any such controlling person shall have the right to employ
separate counsel in any such action and partici-

                                       19
<PAGE>
 
pate in the defense thereof, but the fees and expenses of such counsel shall be
at the expense of the Underwriter or such controlling person unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the Company, (ii) the Company and/or the Selling Stockholders shall have failed
to assume the defense and employ counsel or (iii) the named parties to any such
action (including any impleaded parties) include both the Underwriter or such
controlling person and the Company or any Selling Stockholder, as the case may
be, and the Underwriter or such controlling person shall have been advised by
such counsel that there may be one or more legal defenses available to it which
are different from or additional to those available to the Company or the
Selling Stockholders, as the case may be (in which case the Company and the
Selling Stockholders shall not have the right to assume the defense of such
action on behalf of the Underwriter or such controlling person, it being
understood, however, that the Company and the Selling Stockholders shall not, in
connection with any one such action or separate but substantially similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the fees and expenses of more than
one separate firm of attorneys (in addition to any local counsel) for the
Underwriter and its controlling persons, which firm shall be designated in
writing by the Underwriter and that all such fees and expenses shall be
reimbursed as they are incurred). Neither the Company nor a Selling Stockholder
shall be liable for any settlement of any such action effected without its
written consent, but if settled with its written consent, the Company and/or
such Selling Stockholder agrees to indemnify and hold harmless the Underwriter
and any such controlling person from and against any loss or liability by reason
of such settlement, subject in the case of the Selling Stockholders to the
limits set forth in subsection (b) above. Notwithstanding the immediately
preceding sentence, if in any case where the fees and expenses of counsel are at
the expense of the indemnifying party and an indemnified party shall have
requested the indemnifying party to reimburse the indemnified party for such
fees and expenses of counsel as incurred, such indemnifying party agrees that it
shall be liable for any settle-

                                       20
<PAGE>
 
ment of any action effected without a written consent if (i) such settlement is
entered into more than ten business days after the receipt by such indemnifying
party of the aforesaid request and (ii) such indemnifying party shall have
failed to reimburse the indemnified party in accordance with such request for
reimbursement prior to the date of such settlement. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

          (d) The Underwriter agrees to indemnify and hold harmless the Company,
its directors, its officers who sign the Registration Statement, any person
controlling the Company within the meaning of Section 15 of the Act or Section
20 of the Exchange Act, each Selling Stockholder and each person, if any,
controlling such Selling Stockholder within the meaning of Section 15 of the Act
or Section 20 of the Exchange Act to the same extent as the foregoing indemnity
to the Underwriter but only with reference to information relating to the
Underwriter furnished in writing by Underwriter expressly for use in the
Registration Statement, the Prospectus or any preliminary prospectus. In case
any action shall be brought against the Company, any of its directors, any such
officer or and person controlling the Company or any Selling Stockholder or any
person controlling such Selling Stockholder based on the Registration Statement,
the Prospectus or any preliminary prospectus and in respect of which indemnity
may be sought against the Underwriter, the Underwriter shall have the rights and
duties given to the Company and/or the Selling Stockholders (except that if the
Company or any Selling Stockholder shall have assumed the defense thereof, the
Underwriter shall not be required to do so, but may employ separate counsel
therein and participate in the defense thereof but the fees and expenses of such
counsel shall be at the expense of the Underwriter), and the Company, its
directors, any such officers and any person controlling the Company and the
Selling Stockhold-

                                       21
<PAGE>
 
ers and any person controlling such Selling Stockholders shall have the rights
and duties given to the Underwriter, by Section 8(c) hereof.

          (e) If the indemnification provided for in this Section 8 is
unavailable to an indemnified party in respect of any losses, claims, damages,
liabilities or judgments referred to therein, then each indemnifying party, in
lieu of indemnifying such indemnified party, shall contribute to the amount paid
or payable by such indemnified party as a result of such losses, claims,
damages, liabilities and judgments (i) in such proportion as is appropriate to
reflect the relative benefits received by the Company and the Selling
Stockholders on the one hand and the Underwriter on the other hand from the
offering of the Shares or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Company, the Selling Stockholders and the Underwriter in
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations. The relative benefits received by the Company and the
Selling Stockholders and the Underwriter shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) received by the Selling Stockholders, and the total underwriting
discounts and commissions received by the Underwriter, bear to the total price
to the public of the Shares, in each case as set forth in the table on the cover
page of the Prospectus. The relative fault of the Company and the Selling
Stockholders and the Underwriter shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission to state a material fact relates to information supplied by the
Company, the Selling Stockholders or the Underwriter and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

          The Company, the Selling Stockholders and the Underwriter agree that
it would not be just and equitable if contribution pursuant 

                                       22
<PAGE>
 
to this Section 8(e) were determined by pro rata allocation or by any other
method of allocation which does not take account of the equitable considerations
referred to in the immediately preceding paragraph. The amount paid or payable
by an indemnified party as a result of the losses, claims, damages, liabilities
or judgments referred to in the immediately preceding paragraph shall be deemed
to include, subject to the limitations set forth above any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 8, (a) the Underwriter shall not be required to
contribute any amount in excess of the amount by which the total price at which
the Shares were offered to the public exceeds the amount of any damages which
the Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission and (b) no Selling
Stockholder shall be required to contribute any amount in excess of the amount
of the aggregate purchase price received by such Selling Stockholder for the
sale of such Selling Stockholder's Shares hereunder. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Selling Stockholders' obligations to
contribute pursuant to this Section 8(e) are several in proportion to the
respective number of such Selling Stockholder's Shares sold hereunder.

          (f) Each Selling Stockholder hereby designates the Company as its
authorized agent, upon which process may be served in any action, suit or
proceeding which may be instituted in any state or federal court in the State of
New York by the Underwriter or person controlling the Underwriter asserting a
claim for indemnification or contribution under or pursuant to this Section 8,
and each Selling Stockholder will accept the jurisdiction of such court in such
action, and waives, to the fullest extent permitted by applicable law, any
defense based upon lack of personal 

                                       23
<PAGE>
 
jurisdiction or venue. A copy of any such process shall be sent or given to such
Selling Stockholder, at the address for notices specified in Section 13 hereof.

          9.   Conditions of Underwriter's Obligations. The obligations of the
               ---------------------------------------

          (g) You shall have received on the Closing Date an opinion
(satisfactory to you and counsel for the Underwriter), dated the Closing Date,
of Barry C. Cosgrove, General Counsel of the Company, to the effect that:

              i)   the Company is duly incorporated, validly existing and in
good standing as a corporation under the laws of the State of Delaware and has
the corporate power and authority required to carry on its business as it is
currently being conducted and to own, lease and operate its properties;

              ii)  each Subsidiary of the Company has been duly incorporated or
formed, is validly existing as a corporation in good standing under the laws of
its jurisdiction of incorporation or as a partnership duly formed and has the
corporate or partnership power and authority, as the case may be, to carry on
its business as it is currently being conducted and to own, lease and operate
its properties, and, to such counsel's knowledge after due inquiry, each
corporate Subsidiary is duly qualified and is in good standing as a foreign
corporation and each Subsidiary is authorized to do business in each
jurisdiction in which the nature of its business or its ownership or leasing of
property requires such qualification or authorization, except where the failure
to be so qualified or authorized and be in good standing could not, in the
aggregate, reasonably be expected to have a material adverse effect on the
business, operations, properties, or financial or other condition of the Company
and its Subsidiaries, considered as a whole;

              iii) except as disclosed in the Prospectus,(i) all of the
outstanding shares of capital stock of each of the Company's corporate
Subsidiaries have been duly authorized and validly issued and are fully paid and

indirectly by the Company, free and clear of any Liens and (ii) all of the

Subsidiaries have been duly authorized by its respective partner-

                                       29
<PAGE>
 
ship agreement and validly issued and to such counsel's knowledge after due
inquiry the partnership interests in such partnerships that are not owned by
unaffiliated third parties are owned directly or indirectly by the Company, free
and clear of any Liens and, to such counsel's knowledge, any partnership capital
contribution obligations of the Company in each partnership Subsidiary have been
satisfied;

               iv) all the outstanding shares of Common Stock have been duly
authorized and validly issued and are fully paid, non-assessable and not subject
to any preemptive or similar rights;

                v) neither the Company nor any of its Subsidiaries is in
violation of its respective charter, by-laws or partnership agreement, as the
case may be, and, to the best of such counsel's knowledge after due inquiry,
neither the Company nor any of its Subsidiaries is in default in any material
respect, and no condition exists that with notice or lapse of time or both would
constitute a material default, in the performance of any material obligation,
agreement or condition contained in any bond, debenture, note or any other
evidence of indebtedness or in any other agreement, indenture or instrument to
which the Company or any of its Subsidiaries is a party or by which it or any of
its Subsidiaries or their respective property is bound except to the extent such
violation or default, if any, could not reasonably be expected to have a
material adverse effect on the business, operations, properties or financial or
other condition of the Company and its Subsidiaries, considered as a whole;

               vi) the execution, delivery and performance of this Agreement,
compliance by the Company with all the provisions hereof and the consummation of
the transactions contemplated hereby will not conflict with or constitute a
breach of any of the terms or provisions of, or a default under any agreement,

a party or by which the Company or any of its subsidiaries or their respective
properties are bound, or violate or conflict with any laws, administrative
regulations or rulings or court decrees applicable to the Company or any of its
subsidiaries or their respective properties, except to the extent such
violation, 

                                       30
<PAGE>
 
conflict, breach or default, if any, could not reasonably be expected to have a
material adverse effect on the business, operations, properties or financial or
other condition of the Company and its Subsidiaries, considered as a whole;

              vii) after due inquiry, such counsel does not know of any legal or
governmental proceeding pending or threatened to which the Company or any of its
Subsidiaries is a party or to which any of their respective property is subject
which is required to be described in the Registration Statement or the
Prospectus and is not so described, or of any contract or other document which
is required to be described in the Registration Statement or the Prospectus or
is required to be filed as an exhibit to the Registration Statement which is not
described or filed as required;

             viii) other than as set forth in the Shareholders Agreement or
otherwise described in the Prospectus, to the best of such counsel's knowledge,
after due inquiry, no holder of any security of the Company has any right to
require registration of shares of Common Stock or any other security of the
Company;

               ix) to the best of such counsel's knowledge, after due inquiry,

result in any material adverse change in the business, prospects, financial
condition or results of operation of the Company and its subsidiaries taken as a
whole, and the Company and its subsidiaries enjoy peaceful and undisturbed
possession under all such leases to which any of them is a party as lessee with
such exceptions as do not materially interfere with the use made by the Company
or such subsidiary;

                x) each of the Facilities has such licenses, certifications and
authorizations of governmental or regulatory authorities which are required in
connection with the provision by the Facilities of dialysis services under
applicable licensure, Medicare or Medicaid laws in the manner described in the
Prospectus and which are required to be held by the Facilities as providers of
dialysis services under the Medicare or Medicaid programs; and

                                       31
<PAGE>
 
              xi)(1) each document filed pursuant to the Exchange Act and
incorporated by reference in the Registration Statement and the Prospectus

respects with the Exchange Act and the applicable rules and regulations of the
Commission thereunder, (2) the Registration Statement and the Prospectus and any

the documents incorporated by reference therein) and the prospectus included
therein at the time the Registration Statement became effective did not contain
any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not

                                August 11, 1997

                                                                      21-163-001


Ladies and Gentlemen:

          I am the General Counsel of Total Renal Care Holdings, Inc., a
Delaware corporation (the "Company").  I am delivering this opinion in
connection with the registration under the Securities Act of 1933, as amended
(the "1933 Act"), of the sale in an underwritten public offering of up to
2,750,000 shares of the Common Stock, $0.001 par value per share up (the
"Shares").  This opinion is delivered in connection with that certain
Registration Statement on Form S-3 (the "Registration Statement") to be filed
with the Securities and Exchange Commission (the "Commission") under the 1933
Act.

          In rendering the opinion set forth herein, I have made such
investigations of fact and law, and examined such documents and instruments, or
copies thereof established to my satisfaction to be true and correct copies
thereof, as I have deemed necessary under the circumstances.

          Based upon the foregoing and such other examination of law and fact as
I have deemed necessary, and in reliance thereon, I am of the opinion that the
