                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by reference to, and
should be read in conjunction with, the more detailed information and financial
statements, including notes thereto, appearing elsewhere in this Prospectus.
Prospective investors should also review carefully the information set forth
under "Risk Factors." Unless otherwise indicated, the information in this
Prospectus assumes no exercise of the Underwriters' over-allotment option.
 
                                  THE COMPANY
 
     Renal Care Group is a specialized provider of nephrology services to
patients with kidney disease, including patients suffering from chronic kidney
failure, also known as end-stage renal disease ("ESRD"). The Company provides
dialysis and ancillary services to approximately 5,000 patients through 77
outpatient dialysis centers in 12 states and manages an additional eight
dialysis centers in five states in affiliation with leading medical centers such
as Vanderbilt University Medical Center and The Cleveland Clinic Foundation. In
addition to its outpatient dialysis center operations, Renal Care Group provides
acute dialysis services through contractual relationships with 42 hospitals,
staff-assisted dialysis services to 37 skilled nursing facilities and physician
practice management services to 16 of the 59 nephrologists who are affiliated
with the Company's outpatient dialysis centers.
 
     Renal Care Group was formed by leading nephrologists with the objective of
creating an entity with the clinical and financial capability to manage the full
range of care for ESRD patients on a cost-effective basis. The Company is
working in conjunction with its affiliated physicians to develop fully
integrated nephrology networks that will implement clinical protocols designed
to improve outcomes and reduce costly medical complications associated with
ESRD.
 
     Nephrology is the specialized practice of medicine dedicated to providing
care to patients with ESRD and other kidney-specific ailments. A key component
of the nephrologist's practice is the dialysis facility, where ESRD patients
receive their dialysis treatments three times per week in a technologically
advanced outpatient setting. Outpatient dialysis facilities generally are owned
by nephrology groups and comprise an integral component of the nephrologist's
practice because of the critical role that dialysis plays in the treatment of
ESRD patients. According to the Health Care Financing Administration ("HCFA"),
there were in excess of 2,800 dialysis centers in the United States at the end
of 1995. The Company believes that approximately 38% were owned by multi-center
dialysis companies, 32% were owned by independent physicians and 30% were
hospital-based centers. Although numerous nephrology groups have in the past
sold their dialysis centers to entities engaged in the business of owning and
operating such facilities, the Company believes that many nephrology groups
recognize the need to affiliate with an entity having broader capabilities that
can provide clinical, financial and business expertise to help them manage the
increasingly complex and time-consuming aspects of both their dialysis center
operations and their nephrology practices. In addition, many hospitals are
motivated to sell or outsource management of their dialysis facilities as they
refocus their resources on their core business in response to increasing
competitive pressures.
 
     ESRD is the state of advanced renal impairment that is irreversible and
imminently lethal. ESRD patients require dialysis or kidney transplantation to
sustain life, with dialysis being the form of treatment provided to
approximately 94% of ESRD patients in 1995. Since 1972, individuals with ESRD
have been entitled to Medicare benefits regardless of age or financial
circumstances. According to data published by HCFA, the number of patients
receiving chronic dialysis services in the United States has grown at a compound
annual growth rate of 8.9%, from 66,000 patients in 1982 to approximately
200,000 in 1995. According to the United States Renal Data System ("USRDS"), the
ESRD incidence rate among Medicare-eligible patients increased by 97.3% from
1984 to 1993. The USRDS estimates that the total direct medical charges for ESRD
were approximately $11.1 billion in 1994. The Company attributes the growth in
the number of ESRD patients principally to the aging of the general population
and better treatment and survival of patients with hypertension, diabetes and
other illnesses that lead to chronic kidney disease. In addition, improved
technology has enabled older patients and those who previously could not
tolerate dialysis due to other illnesses to benefit from this life-sustaining
treatment. The Company believes these trends will result in
 
                                        3
<PAGE>   5
 
continued growth in the number of ESRD patients and increased demand for
dialysis and associated nephrology services.
 
     Renal Care Group's objective is to develop fully integrated nephrology
provider networks to assume and manage the clinical and financial risk
associated with providing renal disease management services on a capitated
basis. The Company seeks to achieve this objective by (i) acquiring, developing
and managing outpatient and university-based dialysis centers, (ii) integrating
its dialysis centers with affiliated nephrology practices, (iii) developing a
protocol-driven ESRD management model to enhance clinical outcomes and (iv)
providing an appropriate range of ancillary services to ESRD patients. The
Company believes an integrated network of nephrologists and dialysis centers,
combined with the Company's clinical expertise, management experience and access
to capital, will provide significant advantages to patients and third-party
payors by improving the quality of care while reducing the overall costs
associated with treating patients with all forms of kidney disease, including
those who have ESRD.
 
                              RECENT DEVELOPMENTS
 
     On September 30, 1996, the Company completed a merger with RenalWest, L.C.
("RenalWest") which was accounted for as a pooling of interests. RenalWest,
which has 18 affiliated nephrologists, operates 19 freestanding hemodialysis
centers and three home peritoneal dialysis centers serving approximately 1,200
patients in the state of Arizona. RenalWest also provides inpatient dialysis
services to 16 acute care hospitals and staff-assisted dialysis services to 37
skilled nursing facilities.

(1) The Combination was accounted for using historical cost, in accordance with
     Securities and Exchange Commission Staff Accounting Bulletin No. 48,
     because no single owner group from any of the Founding Companies held more
     than a 50% equity interest in the Company as of the closing of the
     Company's initial public offering. Accordingly, the Company has recorded
     the net assets acquired at the Founding Companies' historical cost basis,
     as determined by generally accepted accounting principles.
(2) Pro forma information for the year ended December 31, 1995 gives effect to
     (a) the provision for federal and state income taxes as if not-for-profit
     and S-corporations had been subject to such taxes; (b) additional estimated
     corporate overhead of approximately $2.6 million that would have been
     incurred

     Financial Statements of Renal Care Group, Inc. (of Delaware).
(4) The calculation of pro forma earnings per share for the year ended December
     31, 1995 excludes 1,156,000 shares of Common Stock issued in the initial
     public offering. The net proceeds from these shares were used for general
     corporate purposes and therefore are excluded from the calculation. All
     subsequent periods reflect the full impact of all shares issued in the
     initial public offering.
(5) Adjusted to reflect the sale of 1,500,000 shares offered by the Company
     hereby at an assumed public offering price of $36.25 per share and the
     application of the net proceeds therefrom.
(6) Treatments include all hemodialysis treatments provided in outpatient
     facilities, as well as all home dialysis treatments and acute care
     treatments provided in hospitals. Peritoneal dialysis treatments are stated
     in hemodialysis equivalents. Excludes treatments provided at centers
     managed by the Company.
(7) Number of ESRD patients under care of outpatient centers at period-end,
     including patients receiving treatments at the Company's outpatient centers
     and in the patient's homes. Excludes patients receiving care at centers
     managed by the Company.

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, the following risk
factors should be considered carefully in evaluating the Company and its
business before purchasing shares of Common Stock offered hereby. This
Prospectus contains certain forward-looking statements which involve risks and
uncertainties. The Company's actual results could differ materially from the
results anticipated in these forward-looking statements as a result of the risk
factors set forth below and other factors described elsewhere in this
Prospectus.
 
LIMITED COMBINED OPERATING HISTORY
 
     Renal Care Group has conducted operations as a combined entity only since
February 1996, when it acquired the Founding Companies effective upon the
closing of its initial public offering. Since the initial public offering, the
Company has made several additional acquisitions of entities that, in some
cases, have been part of the Company's combined operations for only a few weeks
or months. In particular, the Company's recent acquisition of RenalWest may
place significant demands on the Company's management and other resources, and
there can be no assurance that the Company will be able to integrate the
business operations of RenalWest successfully or that there will be any
operating efficiencies or economies of scale between the businesses. Further,
there can be no assurance that the Company will be able to integrate the
dialysis centers, information systems and related operations of the entities
acquired by it or to continue operating them profitably. Nor can there be any
assurance that the Company's management group will be able to implement
effectively the Company's operating and growth strategy while it is engaged in
acquisition activity. Failure to integrate successfully the centers and other
operations acquired by the Company or to implement effectively the Company's
operating and growth strategy could have a material adverse impact on the
Company's results of operations, financial condition and business. See
"Business -- Strategy."
 
DEPENDENCE ON GOVERNMENT REIMBURSEMENT
 
     Renal Care Group is reimbursed for dialysis services primarily at fixed
rates established under the ESRD program administered by HCFA. Under this
program, once a patient becomes eligible for Medicare reimbursement, Medicare is
responsible for payment of 80% of the composite rate determined by HCFA for
dialysis treatments. Since 1972, qualified patients with ESRD have been entitled
to Medicare benefits regardless of age or financial circumstances. The Company
estimates that approximately 68%, 68% and 67% of its net revenue for the years
ended December 31, 1994 and 1995 and for the six months ended June 30, 1996,
respectively, consisted of reimbursements from Medicare under the ESRD program,
including revenue for the reimbursement of the administration of a
bio-engineered hormone, erythropoietin ("EPO"), to treat anemia. Since 1983,
Congressional actions have resulted in occasional changes in the Medicare
composite reimbursement rate, and the Company is not able to predict whether
future rate changes will be made. In August 1996, HCFA announced that an
increase in the composite rate may be appropriate within the next few years.
However, in making this announcement, HCFA also noted that any rate increase
must be considered in the context of Medicare budgetary concerns. HCFA stated
that it may recommend an update to the composite rate for fiscal year 1998.
Legislation or regulations may be enacted in the future that may significantly
modify the ESRD program or otherwise affect the amount paid for the Company's
services. Any such action could have a material adverse effect on the Company's
results of operations, financial condition and business. Furthermore, increases
in operating costs that are subject to inflation, such as labor and supply
costs, without a compensating increase in prescribed rates, may have a material
adverse effect on the Company's earnings in the future. The Company is also
unable to predict whether certain ancillary services, for which the Company
currently is reimbursed separately, may in the future be included in the
Medicare composite rate. See "Business -- Reimbursement -- Medicare
Reimbursement Rates."
 
     Since June 1, 1989, the Medicare ESRD program has provided reimbursement
for the administration of EPO to dialysis patients. EPO is beneficial in the
treatment of anemia, a medical complication frequently experienced by dialysis
patients. The Company believes that in excess of 80% of its patients receive
EPO. Revenues from the administration of EPO (the substantial majority of which
are reimbursed through Medicare and Medicaid programs) were approximately 18%,
17% and 18% of the net revenue of the Company
 
                                        7
<PAGE>   9
 
for each of the years ended December 31, 1994 and 1995 and for the six months
ended June 30, 1996, respectively. EPO reimbursement significantly affects the
Company's earnings. Any reduction in reimbursement rates for EPO could have a
material adverse effect on the Company's results of operations, financial
condition and business. EPO is produced by a single manufacturer, and any
interruption of supply or product cost increases could have a material adverse
effect on the Company's business. See "Business -- Reimbursement -- Medicare
Reimbursement Rates."
 
     All of the states in which the Company currently operates dialysis centers
provide Medicaid (or comparable) benefits to qualified recipients to supplement
their Medicare entitlement. The Company estimates that approximately 8%, 7% and
7%, of the Company's net revenue for the years ended December 31, 1994 and 1995
and for the six months ended June 30, 1996, respectively, 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. See
"Business -- Reimbursement -- Medicaid Reimbursement" and
"Business -- Government Regulation."
 
DEPENDENCE ON OTHER SOURCES OF REIMBURSEMENT
 
     The Company estimates that approximately 24%, 25% and 26% of its net
revenue for the years ended December 31, 1994 and 1995 and for the six months
ended June 30, 1996, respectively, were derived from sources other than Medicare
and Medicaid. Substantially all of this revenue comes from private insurance for
chronic dialysis treatments and payments from hospitals with which the Company
has contracts for the provision of acute dialysis services. In general, private
insurance reimbursement and payments for treatments performed at hospitals are
at rates significantly higher than Medicare and Medicaid rates. The Company
believes that if Medicare reimbursement for dialysis treatment is reduced in the
future, these private payors may be required to assume a greater percentage of
the costs of dialysis care and, as a result, may focus on reducing dialysis
payments as their overall costs increase. In addition, the Company believes that
health maintenance organizations ("HMOs") and other managed care providers may
have a strong incentive to reduce further the costs of specialty care and may
seek to reduce amounts paid for dialysis. The Company is unable to predict
whether and to what extent changes in these private reimbursement rates may be
made in the future. Any reduction in the rates paid by private insurers and
hospitals or a significant change in the Company's payor mix towards additional
Medicare or Medicaid reimbursement could have a material adverse effect on the
Company's results of operations, financial condition and business. Similarly,
increases in operating costs that are subject to inflation, such as labor and
supply costs, without a compensating increase in private reimbursement rates,
could have a material adverse effect on the Company's results of operations,
financial condition and business. See "Business -- Operations" and "--
Reimbursement."
 
RISKS ASSOCIATED WITH GROWTH STRATEGY
 
     The Company's strategy includes expanding its dialysis business through the
acquisition and development of dialysis centers and the acquisition and
management of nephrology practices. Competition for acquisitions in the dialysis
industry has increased significantly in recent years and, as a result, the cost
of acquiring dialysis centers has increased. There can be no assurance that the
Company will be able to identify, acquire or profitably integrate acquired
dialysis centers and nephrology practices. Acquisitions involve a number of
risks related to integration, including adverse short-term effects on the
Company's reported operating results, diversion of management's attention,
dependence on retention, hiring and training of key personnel, including Medical
Directors for each dialysis center, some or all of which could have a material
adverse effect on the Company's results of operations, financial condition and
business. In addition, there can be no assurance that acquired or managed
dialysis centers will achieve net revenue and earnings that justify the
Company's investment therein or expenses related thereto. In order to implement
its growth strategy, the Company may require substantial capital resources and
need to incur, from time to time, short- and long-term bank indebtedness. The
Company also may need to issue, in public or private transactions, equity or
debt securities, the terms of which will depend on market and other conditions.
There can be no assurance that any such
 
                                        8
<PAGE>   10
 
additional financing will be available on terms acceptable to the Company, if at
all. To the extent that the Company is unable to acquire dialysis centers or
acquire or manage nephrology practices, to integrate such centers and practices
successfully, or to obtain financing on terms acceptable to the Company, its
ability to expand its business could be reduced significantly. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources" and "Business -- Strategy."
 
DEPENDENCE ON PHYSICIAN REFERRALS
 
     The Company's dialysis centers depend upon their Medical Directors and
other local nephrologists for referrals of ESRD patients for treatment and one
or a few physicians typically account for all or a significant portion of the
patient referral base at a center. The loss of one or more referring physicians
at a particular center could have a material adverse effect on the operations of
such center, and the loss of a significant number of referring physicians could
have a material adverse effect on the Company's results of operations, financial
condition and business. The illegal remuneration provisions of the Social
Security Act and similar state laws prohibit the payment of remuneration to
induce referrals. Furthermore, in many instances stockholders of the Company are
the primary referral sources for the dialysis centers operated by the Company.
If such ownership is deemed to violate applicable federal or state law, such
physician owners may be forced to dispose of their stock in the Company. The
Company cannot predict the effect such disposition would have on its business or
stock price. See "Business -- Operations -- Relationships With Referral Sources;
Medical Directors" and "Business -- Government Regulation."
 
OPERATIONS SUBJECT TO EXTENSIVE GOVERNMENT REGULATION
 
     The Company is subject to extensive federal, state and local regulation
regarding, among other things, fraud and abuse, patient referral, health and
safety, environmental compliance and toxic waste disposal. Much of this
regulation, particularly in the area of patient referral, is complex and open to
differing interpretations. There are two general frameworks under which patient
referrals are regulated. First, the illegal remuneration provisions of the
Social Security Act make it illegal for any person to, among other things,
solicit, offer, receive or pay any remuneration in exchange for referring, or to
induce the referral of, a patient for treatment which may be paid for by
Medicare, Medicaid or a similar state program. Second, certain provisions
contained in the Omnibus Budget Reconciliation Act of 1989 and the Omnibus
Budget Reconciliation Act of 1993 ("Stark I" and "Stark II," respectively)
prohibit physician referrals for clinical laboratory services and "designated
health services" (including some of the specific services offered by the
Company) to entities with which a physician or an immediate family member has a
"financial relationship." These laws contain certain statutory exceptions, and
federal agencies have promulgated regulations clarifying certain of these
provisions and exceptions and creating certain additional exceptions, or "safe
harbors," from such prohibitions. Many states have enacted similar provisions of
law, which may not have identical prohibitions or exceptions, but which may
apply regardless of whether Medicare or Medicaid funds are involved. However,
due to the breadth of the statutory provisions and the absence in many instances
of regulations or court decisions addressing the specific arrangements by which
the Company conducts its business, it is possible that some of the Company's
practices might be challenged under these laws. Violations of the federal laws
are punishable by civil sanctions, including disqualification from participation
in the Medicare or Medicaid programs, and, in the case of the federal illegal
remuneration provisions, criminal sanctions. There can be no assurance that the
Company's practices will not be challenged by governmental authorities, or that
the Company will not be subject to sanctions under such laws or be required to
alter or discontinue certain of its practices. In addition, there can be no
assurance that if the Company is required to alter its practices, that it will
be able to do so successfully. The occurrence of any of these events may result
in a material adverse effect on the Company's net revenues and earnings. See
"Business -- Government Regulation."
 
     A number of proposals for health care reform have been made recently to
provide greater governmental control of health care spending and to provide
broader access to health care services. For example, the Health Insurance
Portability and Accountability Act of 1996 was signed into law in August 1996.
This law, among other things, provides for insurance portability for individuals
who lose or change jobs, limit exclusions
 
                                        9
<PAGE>   11
 
for pre-existing conditions, and establish a pilot program for medical savings
accounts. It is uncertain what additional health care reform legislation, if
any, ultimately will be implemented or whether other changes in the
administration or interpretation of governmental health care programs will
occur. The Company cannot predict what effect future health care legislation or
other changes in the administration or interpretation of governmental health
care programs may have on the Company's operations. See "Business -- Government
Regulation -- Health Care Legislation."
 
SUBSTANTIAL COMPETITION
 
     The dialysis industry is fragmented and is consolidating rapidly.
Accordingly, the industry is highly competitive, particularly from the
standpoint of competition for the acquisition of existing dialysis centers and
the development of relationships with referring physicians. Many of the
Company's competitors have substantially greater financial resources and more
established operations and infrastructure than the Company and may compete with
the Company for acquisitions of dialysis centers and nephrology practices. In
addition, the Company may also experience competition from referring physicians
who open their own dialysis centers. There can be no assurance that the Company
will be able to compete effectively with any such competitors. See
"Business -- Competition."
 
DELAYS AND COSTS OF IMPLEMENTING INTEGRATED OPERATING SYSTEMS
 
     The Company is in the process of implementing and integrating certain
information and operating systems for its centers, all of which have been
acquired within the last several months. The Company may experience delays,
complications and expenses in implementing, integrating and operating such
systems, any of which could have a material adverse effect on the Company's
results of operations, financial condition and business. Furthermore, while the
Company believes that the technology that it implements will be adequate for the
Company's current needs, such systems may require modification, improvement or
replacement as the Company expands or if new technologies render the Company's
systems obsolete. Such modifications, improvements or replacements may require
substantial expenditures to design and implement and may require interruptions
in operations during periods of implementation, any of which could have a
material adverse effect on the Company's results of operations, financial
condition and business. See "Business -- Operations."
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company is dependent upon the services of certain key executive
officers and the Chairman of the Board. The Company's growth will depend in part
upon its ability to attract and retain skilled employees, for whom competition
is intense. The Company believes that its future success will also depend on its
ability to attract and retain qualified physicians to serve as Medical Directors
of its dialysis centers. The Company does not carry key-man life insurance on
any of its officers. The loss by the Company of any of its executive officers or
the Chairman of the Board, or the inability to attract and retain qualified
management personnel and Medical Directors, could have a material adverse effect
on the Company's results of operations, financial condition and business. See
"Management."
 
SIGNIFICANT INFLUENCE BY MANAGEMENT AND PHYSICIAN STOCKHOLDERS
 
     Upon completion of the Offering, the Company's directors, executive
officers and physician stockholders will beneficially own approximately      %
of the outstanding shares of Common Stock (      % if the Underwriters'
over-allotment option is exercised in full). The Company's Amended and Restated
Certificate of Incorporation and Bylaws do not provide for cumulative voting.
Although directors, executive officers and physician stockholders do not have
any arrangements or understandings among themselves with respect to the voting
of the shares of Common Stock beneficially owned by such persons, such persons
acting together would be able to significantly influence the election of
directors and might be able to approve or disapprove any matter submitted to a
vote of stockholders, including a change in control in the Company. See
"Management" and "Principal and Selling Stockholders."
 
                                       10
<PAGE>   12
 
POTENTIAL CONFLICTS OF INTEREST
 
     The Company is a party to Medical Director agreements with Stephen D.
McMurray, M.D., W. Tom Meredith, M.D., Thomas A. Lowery, M.D., John D. Bower,
M.D. and Kenneth E. Johnson, M.D., each of whom is a director and stockholder of
the Company. In addition, the Company leases space from Dr. Bower, Dr. Lowery,
and an entity in which Dr. Meredith owns a one-third interest. The chairman of
the Company, Harry R. Jacobson, M.D., serves as Deputy Vice Chancellor of Health
Affairs at Vanderbilt University, and the Company has an agreement with
Vanderbilt University Medical Center to manage its outpatient dialysis facility.
The outside interests of these directors may give rise to certain conflicts of
interest concerning the fulfillment of their responsibilities as directors of
the Company, and such conflicts of interest could result in decisions that may
not reflect the interests of all stockholders equally. See "Certain
Transactions."
 
ANTI-TAKEOVER EFFECTS OF CERTAIN CHARTER AND BYLAW PROVISIONS
 
     The Company's Amended and Restated Certificate of Incorporation and Bylaws
contain a number of provisions that could inhibit a change in control of the
Company by means of a tender offer, merger, proxy contest or otherwise,
including advance notice and super-majority voting provisions, provisions that
establish a classified board of directors, and provisions that enable the Board
of Directors to issue "blank check" preferred stock. See "Description of Capital
Stock -- Special Provisions of the Amended and Restated Certificate of
Incorporation, Bylaws and Delaware Law."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
     The market price of the Common Stock may fluctuate substantially in
response to variations in the Company's operating and financial results, changes
in earnings estimates by securities analysts, general economic and market
conditions, and other factors. See "Price Range of Common Stock."
 
POTENTIAL ADVERSE MARKET IMPACT OF SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of substantial amounts of Common Stock in the public market or the
availability of such shares for sale following the Offering could adversely
affect the prevailing market price for the Common Stock. After completion of the
Offering, the Company will have 14,125,954 shares of Common Stock outstanding
(14,575,954 if the Underwriters' over-allotment option is exercised in full). Of
those shares, approximately 7,485,000 shares, including the 3,000,000 shares
offered hereby (7,935,000 and 3,450,000 shares, respectively, if the
Underwriters' over-allotment option is exercised in full), will be freely
tradeable without restriction or further registration under the Securities Act,
unless purchased by "affiliates" of the Company, as that term is defined in Rule
144 under the Securities Act of 1933, as amended (the "Securities Act"). In
addition, up to 1,831,993 shares of Common Stock are issuable upon the exercise
of options which will be freely tradeable without restriction unless purchased
by an "affiliate." The remaining approximately 6,640,954 shares outstanding,
plus up to 404,000 shares of Common Stock which may be issued upon exercise of
warrants or conversion of convertible securities, will become eligible for
future sale in the public market in accordance with Rule 144 under the
Securities Act, as currently in effect, beginning in February 1998. The Company
has granted certain "piggyback" registration rights with respect to shares of
Common Stock to the holders of a total of approximately 6,640,954 shares of
Common Stock and 220,000 shares issuable upon the conversion of warrants, such
"piggyback" registration rights not being exercisable except in connection with
a Company registration. The Company's officers and directors, and certain
stockholders of the Company, who upon completion of the Offering will own an
aggregate of approximately             shares of Common Stock, have agreed not
to, directly or indirectly, offer, sell, contract to sell, grant any option to

                                  THE COMPANY
 
     Renal Care Group is a specialized provider of nephrology services that was
founded in June 1995 to focus on the provision of care to patients with kidney
disease, including patients suffering from chronic kidney failure. In February
1996, the Company commenced its business with the simultaneous acquisition in
the Combination of the five Founding Companies: Kidney Care, Inc. and Medical
Enterprises Ltd. ("MEL" and collectively "Kidney Care"); D.M.N. Professional
Corporation ("DMN"); Tyler Nephrology Associates ("Tyler"); Kansas Nephrology
Association ("Kansas"); and Renal Care Group, Inc., a Tennessee corporation
("Tennessee"). At the time of the Combination, the Founding Companies had an
aggregate of 41 dialysis centers serving approximately 2,663 patients in eight
states. The aggregate consideration paid by the Company in the Combination was
approximately 4,834,000 shares of Common Stock with an aggregate value at the
time of the Combination of approximately $87.0 million, $32.8 million in cash,
$7.3 million in notes payable and $13.8 million of assumed debt.
 
     On April 26, 1996, the Company completed a merger with Main Line Suburban
Dialysis, Inc. ("Main Line"). Main Line, based in Wynnewood, Pennsylvania,
operates five dialysis centers serving approximately 350 patients in the
suburban Philadelphia area. The Company acquired Main Line in exchange for
shares of Common Stock with an aggregate value of approximately $18.2 million at
the time the Company and Main Line entered into the merger agreement. The merger
was accounted for as a pooling of interests.
 
     On July 1, 1996, the Company completed a merger with The Nephrology
Centers, Inc. ("TNC"), which is based in Pensacola, Florida and operated two
dialysis centers serving approximately 250 patients in the Pensacola and
Crestview, Florida areas. TNC constructed two additional satellite centers which
opened in September 1996. The Company acquired TNC in exchange for shares of
Common Stock with an aggregate value of approximately $10.2 million at the time
the Company and TNC entered into the merger agreement. The merger was accounted
for as a pooling of interests.
 
     On September 30, 1996, the Company completed a merger with RenalWest, which
has 18 affiliated nephrologists and operates 19 freestanding hemodialysis
centers and three home peritoneal dialysis centers serving approximately 1,200
patients in the state of Arizona. RenalWest also provides inpatient dialysis
services to 16 acute care hospitals and staff-assisted dialysis services to 37
skilled nursing facilities. The Company acquired RenalWest in exchange for
shares of Common Stock with an aggregate value of approximately $72.0 million at
the time the Company and RenalWest entered into the merger agreement. The merger
was accounted for as a pooling of interests.
 
     In February 1996, the Company entered into an agreement to develop a
dialysis center for the University of Louisville. In April 1996, the Company
announced an agreement to operate and manage the outpatient dialysis activities
of The Cleveland Clinic Foundation located in Cleveland, Ohio. The Cleveland
Clinic Foundation operates two dialysis facilities staffed by 11 nephrologists
serving approximately 370 patients.
 
     The Company's address is 2100 West End Avenue, Suite 800, Nashville,
Tennessee 37203, and its telephone number is (615) 321-2333.

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 1,500,000 shares of
Common Stock offered by it, at an assumed public offering price of $36.25 per
share, are estimated to be approximately $51.3 million after deducting estimated
underwriting discounts and offering expenses payable by the Company, (or
approximately $66.8 million if the Underwriters' over-allotment option is
exercised in full). The net proceeds will be used for working capital and
general corporate purposes, including the potential acquisition and development
of additional dialysis centers. The Company continually reviews and evaluates
acquisition candidates as part of its growth strategy and is at various stages
of evaluation, discussion or negotiation with a number of such candidates. The
Company is not a party to any definitive agreement or letter of intent regarding
any material acquisition, nor are there any material acquisitions that it
considers probable. Pending application of the net proceeds as described above,
the Company intends to invest the net proceeds in short-term, interest-bearing,
investment-grade securities. The Company will not receive any proceeds from the
sale of shares of Common Stock offered by the Selling Stockholders. See
"Principal and Selling Stockholders."

                                DIVIDEND POLICY
 
     The Company has never paid any cash dividends on its capital stock. The
Company currently anticipates that all of its earnings will be retained to
finance the growth and development of its business and, therefore, does not
anticipate that any cash dividends will be declared or paid on the Common Stock
in the foreseeable future. Any future declaration of dividends will be subject
to the discretion of the Company's Board of Directors and its review of the
Company's results of operations, financial condition, capital requirements and
surplus, contractual restrictions to pay such dividends and other factors it
deems relevant.

                SELECTED HISTORICAL AND COMBINED FINANCIAL DATA
 
     The Selected Historical Financial Data -- Renal Care Group, Inc. represent
the historical results of operations of the Company and includes the results of
operations of Main Line and RenalWest, which were acquired during 1996 in
pooling-of-interests transactions; however, this information does not include
the results of operations for the Founding Companies for any periods prior to
the six months ended June 30, 1996 except on a pro forma basis.
 
     The Selected Combined Financial Data -- Renal Care Group, Inc. and Founding
Companies represent the results of operations had the Founding Companies and the
Company been combined on January 1, 1991 without giving effect to the initial
public offering for periods prior to February 1, 1996 except on a pro forma
basis.
 
     The Combination was accounted for using historical cost, in accordance with
Securities and Exchange Commission Staff Accounting Bulletin No. 48, because no
single owner group from any of the Founding Companies held more than 50% equity
interest in the Company as of the closing of the Company's initial public
offering. Accordingly, the Company has recorded the net assets acquired at the
Founding Companies' historical cost basis, as determined by generally accepted
accounting principles.
 
     The Selected Historical Financial Data -- Renal Care Group, Inc. for the
years ended December 31, 1994 and 1995 and the Selected Combined Financial
Data -- Renal Care Group, Inc. and Founding Companies for the years ended
December 31, 1993, 1994 and 1995 are derived from audited data included
elsewhere in this Prospectus. The unaudited combined financial statements have
been prepared on the same basis as the audited combined financial statements
and, in the opinion of management, contain all adjustments consisting of normal,
recurring accruals necessary for a fair presentation of the combined financial
position and the combined results of operations for the periods presented. The
following data should be read in conjunction with the financial statements and
related notes and "Management's Discussion and Analysis of Financial Condition
and Results of Operations" that appear elsewhere in this Prospectus.

(3) The financial information for the six months ended June 30, 1996 include the
    results of operations for the Founding Companies since February 1996 when
    they were acquired by the Company simultaneously with its initial public
    offering.
(4) Pro forma information for the six months ended June 30, 1996 gives effect to
    the provision for federal and state income taxes as if not-for-profit and
    S-corporations had been subject to such taxes. See Pro Forma Combining

(5) The calculation of pro forma earnings per share for the year ended December
    31, 1995 excludes 1,156,000 shares of Common Stock issued in the initial
    public offering. The net proceeds from these shares were used for general
    corporate purposes and therefore are excluded from the calculation. All
    subsequent periods reflect the full impact of all shares issued in the
    initial public offering.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the financial
information referenced in the Index to Financial Statements, including the notes
thereto, and the other financial information appearing elsewhere in this
Prospectus.
 
OVERVIEW
 
     Renal Care Group is a specialized provider of nephrology services to
patients with kidney disease, including patients suffering from chronic kidney
failure. The Company commenced operations in February 1996 when it acquired the
Founding Companies simultaneous with the completion of its initial public
offering. At the time of the Combination, the Founding Companies were
established businesses engaged in the operation of outpatient dialysis centers
as separate, independent entities for an average of 14 years. For all periods
presented, the Combined Financial Statements include the financial information
of the Founding Companies, Main Line, a merger which was completed in April
1996, and RenalWest, a merger which was completed in September 1996. Both the
Main Line and RenalWest mergers were accounted for as poolings of interests.
RenalWest was organized in September 1993; consequently, the Combined Financial
Statements do not include a full year of operating results for that period.
Because the Founding Companies, Main Line and RenalWest were independent
entities that had not been operated by the Company's management prior to their
respective dates of acquisition, the historical results prior to such times may
not be indicative of future performance. In addition, the Combined Financial
Statements do not give effect to any operating efficiencies prior to such dates
of acquisition that the Company believes typically would be attainable in an
integrated organization.
 
     Renal Care Group believes that its dialysis centers, on an individual
basis, generally did not have the management, capital and other resources prior
to the Combination and the Company's acquisition that are required to generate
sustainable growth in the increasingly competitive dialysis industry. By
combining the dialysis centers under an experienced executive management team
and providing the combined entity with access to greater financial and other
resources, management believes the Company is positioned to pursue an aggressive
growth strategy comprised of increased internal growth and strategic
acquisitions. Significant factors that influence internal growth in the dialysis
industry include the number of nephrologists associated with a company's
dialysis centers and the availability of capital to fund the development of new
centers. The Company plans to increase internal growth by providing management,
capital and other resources required to develop new centers and to recruit
additional nephrologists to increase utilization of the Company's existing
network of dialysis centers. Since the Combination, the Company has completed
four acquisitions, including Main Line and RenalWest, which added approximately
2,000 ESRD patients, and management believes that additional acquisition
candidates will be available as the dialysis industry continues its rapid
consolidation.
 
     Renal Care Group has implemented company-wide supply, insurance and other
agreements that have resulted in lower operating costs for the combined entity.
Other operating efficiencies that the Company has realized include consolidation
of employee benefits, cash management and other similar functions. The Company
believes it will be able to realize economies of scale in both acquired and
managed operations by consolidating corporate and regional management expenses.
However, a portion of any operating efficiencies that may be achieved will be
offset by the need for increased general and administrative expenses as the
Company adds support services at the corporate headquarters.
 
SOURCES OF NET REVENUE
 
     The Company's net revenue has been derived primarily from the following
sources: (i) outpatient hemodialysis services; (ii) ancillary services
associated with dialysis, primarily the administration of EPO; (iii) home
dialysis services; (iv) inpatient hemodialysis services provided pursuant to
contracts with acute care hospitals and skilled nursing facilities; (v)
management contracts with hospital-based and medical university dialysis
programs; and (vi) laboratory services. ESRD patients typically receive 156
dialysis
 
                                       18
<PAGE>   20
 
treatments per year, with reimbursement for services provided primarily by the
Medicare ESRD program based on rates that are established by HCFA. For the six
months ended June 30, 1996, approximately 74% of the Company's net revenue was
derived from reimbursement under the Medicare and Medicaid programs. Medicare
reimbursement is subject to rate and other legislative changes by Congress and
periodic changes in regulations, including changes that may reduce payments
under the ESRD program. For patients with health insurance, dialysis generally
is reimbursed at rates higher than Medicare during the first 18 months of
treatment, after which time Medicare becomes the primary payor. Reimbursement
for dialysis services provided pursuant to a hospital contract is negotiated
with the individual hospital and generally is higher on a per treatment
equivalent basis than the Medicare rate. Because dialysis is a life-sustaining
therapy used to treat this chronic disease, utilization is predictable and is
not subject to seasonal fluctuations.
 
RESULTS OF OPERATIONS
 
     The results of operations for all periods in the table below and in the
period comparisons that follow reflect the historical operations of the Company,
including the operations of Main Line and RenalWest, combined with the
operations of the Founding Companies. However, management of the Company did not
operate the Founding Companies until February 1996, Main Line until April 1996
and RenalWest until September 1996, the respective dates of acquisition of such
companies.
 
     The following table sets forth, for the periods indicated, the percentage
of net revenue represented by the respective financial items:

</TABLE>
 
SIX MONTHS ENDED JUNE 30, 1996 COMPARED TO SIX MONTHS ENDED JUNE 30, 1995
 
     Net Revenue.  Net revenue increased from $56,253,000 for the six months
ended June 30, 1995 to $62,736,000 for the six months ended June 30, 1996, an
increase of $6,483,000, or 11.5%. This increase resulted primarily from a 7.2%
increase in the number of treatments from 309,162 in the 1995 period to 331,280
in the 1996 period and a 3.3% increase in the average revenue per treatment from
$183 in the 1995 period to $189 in the 1996 period. The revenue per treatment
increase was due to an increase in EPO utilization and acute treatments. The
remaining revenue increase resulted from management fee income.
 
     Patient Care Costs.  Patient care costs consist of costs directly related
to the care of patients, including direct labor, drugs, and other medical
supplies and operational costs of facilities. Patient care costs increased from
$39,137,000 for the six months ended June 30, 1995 to $43,883,000 for the six
months ended June 30, 1996, an increase of $4,746,000, or 12.1%. This increase
was due to the increase in the number of treatments, which caused a
corresponding increase in the use of drugs, supplies and labor. Patient care
costs as a percentage of net revenue increased slightly from 69.6% in the 1995
period to 69.9% in the 1996 period, with such increase caused primarily by
higher patient care costs at Main Line and RenalWest. Average patient care cost
per treatment increased from $127 in the 1995 period to $132 in the 1996 period.
This increase was due to normal health care inflation, increased EPO utilization
and the increase in higher cost acute treatments.
 
     General and Administrative Expenses.  General and administrative expenses
include corporate office costs and clinic costs not directly related to the care
of patients, including clinic administration, accounting,
 
                                       19
<PAGE>   21
 
billing and information systems. General and administrative expenses increased
from $6,346,000 for the six months ended June 30, 1995 to $6,417,000 for the six
months ended June 30, 1996, an increase of $71,000, or 1.1%. General and
administrative expenses as a percentage of revenue decreased from 11.3% in the
1995 period to 10.2% in the 1996 period. The net increase was a result of
increased corporate overhead expenses partially offset by reduced compensation
to prior physician owners.
 
     Provision for Doubtful Accounts.  The provision for doubtful accounts
decreased from $2,031,000 for the six months ended June 30, 1995 to $1,196,000
for the six months ended June 30, 1996. The provision for doubtful accounts as a
percentage of net revenue decreased from 3.6% in the 1995 period to 1.9% in the
1996 period. This decrease represented a return to a normal level of provision
for doubtful accounts in the 1996 period from the 1995 period when additional
expense was recorded due to a deterioration in the aging of accounts receivable.
The provision for doubtful accounts is a function of patient mix, billing
practices and other factors. It is the Company's practice to reserve for
doubtful accounts in the period in which revenue is recognized based on
management's estimate of the net collectibility of accounts receivable.
 
     Depreciation and Amortization.  Depreciation and amortization increased
from $1,648,000 for the six months ended June 30, 1995 to $2,158,000 for the six
months ended June 30, 1996, an increase of $510,000, or 30.9%. This increase was
due to the purchase of patient care facilities previously leased, higher than
normal replacement of dialysis machines and the purchase of a clinical computer
system.
 
     Merger Expenses.  Merger expenses of $680,000 represented legal, accounting
and compensation expenses related to the Main Line acquisition. Merger expenses
for the RenalWest acquisition have not yet been determined.
 
     Income from Operations.  Income from operations increased from $7,091,000
for the six months ended June 30, 1995 to $8,402,000 for the six months ended
June 30, 1996, an increase of $1,311,000, or 18.5%. Income from operations as a
percentage of net revenue increased from 12.6% in the 1995 period to 13.4% in
the 1996 period.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
     Net Revenue.  Net revenue increased from $110,670,000 for the year ended
December 31, 1994 to $115,329,000 for the year ended December 31, 1995, an
increase of $4,659,000, or 4.2%. This increase resulted primarily from a 4.5%
increase in the number of treatments from 598,228 in the 1994 period to 625,413
in the 1995 period. Average revenue per treatment remained constant for the 1994
and 1995 periods at $185.
 
     Patient Care Costs.  Patient care costs increased from $75,366,000 for the
year ended December 31, 1994 to $80,417,000 for the year ended December 31,
1995, an increase of $5,051,000, or 6.7%. This increase was due to the increase
in the number of treatments, which caused a corresponding increase in the use of
drugs, supplies and labor. Patient care costs as a percentage of net revenue
increased from 68.1% in the 1994 period to 69.7% in the 1995 period. Average
patient care costs per treatment increased from $126 in the 1994 period to $129
in the 1995 period. This increase was the net result of normal health care
inflation and lower EPO utilization costs.
 
     General and Administrative Expenses.  General and administrative expenses
increased from $12,616,000 for the year ended December 31, 1994 to $12,866,000
for the year ended December 31, 1995, an increase of $250,000, or 2.0%. General
and administrative expenses as a percentage of net revenue decreased from 11.4%
in the 1994 period to 11.2% in the 1995 period. General and administrative
expenses decreased in the 1995 period due to the growth in revenue during the
period.
 
     Provision for Doubtful Accounts.  The provision for doubtful accounts
increased from $2,914,000 for the year ended December 31, 1994 to $3,995,000 for
the year ended December 31, 1995. The provision for doubtful accounts as a
percentage of net revenue increased from 2.6% in the 1994 period to 3.5% in the
1995 period. This increase was due to additional bad debt expense recorded as a
result of a revision in the estimated collectibility of accounts receivable for
RenalWest to reflect the Company's accounts receivable valuation policy.

     Depreciation and Amortization.  Depreciation and amortization increased
from $3,414,000 for the year ended December 31, 1994 to $3,661,000 for the year
ended December 31, 1995, an increase of $247,000, or 7.2%. Depreciation and
amortization as a percentage of net revenue increased from 3.1% in the 1994
period to 3.2% in the 1995 period.
 
     Income from Operations.  Income from operations decreased from $16,360,000
for the year ended December 31, 1994 to $14,390,000 for the year ended December
31, 1995, a decrease of $1,970,000, or 12.0%. Income from operations as a
percentage of net revenue decreased from 14.8% in the 1994 period to 12.5% in
the 1995 period.
 
YEAR ENDED DECEMBER 31, 1994 COMPARED TO YEAR ENDED DECEMBER 31, 1993
 
     Net Revenue.  Net revenue increased from $80,442,000 for year ended
December 31, 1993 to $110,670,000 for the year ended December 31, 1994, an
increase of $30,228,000, or 37.6%. This increase resulted primarily from a 27.3%
increase in the number of treatments from 470,035 in the 1993 period to 598,228
in the 1994 period, with a significant component of treatment growth resulting
from the full-year impact in 1994 of RenalWest which operated for only four
months in 1993. In addition, the average revenue per treatment increased 7.6%
from $172 in the 1993 period to $185 in the 1994 period due to an increase in
acute treatments and greater EPO utilization.
 
     Patient Care Costs.  Patient care costs increased from $58,314,000 for the
year ended December 31, 1993 to $75,366,000 for the year ended December 31,
1994, an increase of $17,052,000, or 29.2%. This increase was due to the
increase in the number of treatments, which caused a corresponding increase in
the use of labor, drugs and supplies. Patient care costs as a percentage of net
revenue decreased from 72.5% in the 1993 period to 68.1% in the 1994 period.
Average patient care costs per treatment increased 0.8%, from $125 in the 1993
period to $126 in the 1994 period. This increase was due to normal health care
inflation, increased EPO utilization, increased acute treatments and the
inclusion of RenalWest as of September 1993.
 
     General and Administrative Expenses.  General and administrative expenses
increased from $6,799,000 for the year ended December 31, 1993 to $12,616,000
for the year ended December 31, 1994, an increase of $5,817,000, or 85.6%.
General and administrative expenses increased as a percentage of net revenue
from 8.5% in the 1993 period to 11.4% in the 1994 period due primarily to the
inclusion of RenalWest as of September 1993 and increases in compensation to
prior physician owners.
 
     Provision for Doubtful Accounts.  The provision for doubtful accounts
increased from $2,010,000 for the year ended December 31, 1993 to $2,914,000 for
the year ended December 31, 1994. The provision for doubtful accounts as a
percentage of net revenue increased from 2.5% in the 1993 period to 2.6% in the
1994 period.
 
     Depreciation and Amortization.  Depreciation and amortization increased
from $2,416,000 for the year ended December 31, 1993 to $3,414,000 for the year
ended December 31, 1994, an increase of $998,000, or 41.3%. This net increase
was due to the purchase of patient care facilities in the normal course of
business and the inclusion of RenalWest as of September 1993.
 
     Income from Operations.  Income from operations increased from $10,903,000
for the year ended December 31, 1993 to $16,360,000 for the year ended December
31, 1994, an increase of $5,457,000, or 50.1%. Income from operations as a
percentage of net revenue increased from 13.6% in the 1993 period to 14.8% in
the 1994 period.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company requires capital primarily for the acquisition and the
development of dialysis centers, the purchase of property and equipment for
existing centers and to finance working capital requirements. At June 30, 1996,
the Company's working capital was $32,019,000, cash and cash equivalents were
$31,292,000 and the Company's current ratio was 2.2:1.
 
                                       21
<PAGE>   23
 
     The Company's net cash provided by operating activities was $10,767,000 in
the six months ended June 30, 1996. Generally, cash provided by operating
activities resulted from net income before depreciation and amortization
expense, partially offset by increases in accounts receivable. The Company's net
cash used in investing activities was $40,740,000 in the six months ended June
30, 1996. Cash used in investing activities resulted from $39,699,000 of cash,
working capital and certain other distributions to the Founding Companies
(including approximately $6,899,000 in distributions to former stockholders of
the Founding Companies) and $4,972,000 of capital expenditures, partially offset
by the $3,893,000 cash balances of the Founding Companies acquired at the time
of the Combination. Cash provided by financing activities was $59,631,000 for
the six months ended June 30, 1996. The Company's initial public offering in
February 1996 resulted in the sale of 4,485,000 shares from which the Company
received $71,842,000 after offering costs. Long-term debt repayments totaled
$9,694,000 and distributions to owners which occurred prior to the initial
public offering were $2,597,000.
 
     The Company's line of credit allows for borrowings of up to $35,000,000 to
be used for acquisitions, working capital and capital expenditures. The line of
credit requires payments of interest only until May, 1998 with the balance
outstanding at that time amortized quarterly over the next three years. The
credit facility bears interest at one of two floating rates selected by the
Company: (i) the base rate plus a margin ranging from 0.00% to 1.00% or (ii)
LIBOR plus a margin of 0.95% to 2.70%.
 
     At October 8, 1996, the Company had $1,380,000 of outstanding Convertible
Notes due in December 1996 that are convertible into Common Stock at a price of
$7.50 per share.
 
     A significant component of the Company's growth strategy is the acquisition
and development of dialysis centers. The Company believes that the net proceeds
from the Offering, existing cash and funds from operations, together with funds
available under the line of credit, will be sufficient to meet the Company's
acquisition, expansion, capital expenditure and working capital needs through at
least the end of 1997. In order to finance certain large strategic acquisition
opportunities, the Company may incur from time to time additional short and
long-term bank indebtedness and may issue equity or debt securities, the
availability and terms of which will depend on market and other conditions.
There can be no assurance that such additional financing, if required, will be
available on terms acceptable to the Company.
 
IMPACT OF INFLATION
 
     A substantial portion of the Company's net revenue is subject to
reimbursement rates that are regulated by the federal government and do not
automatically adjust for inflation. The Company is unable to increase the amount
it receives for the services provided by its dialysis business that are
reimbursed under the Medicare composite rate. Increased operating costs due to
inflation, such as labor and supply costs, without a corresponding increase in
reimbursement rates, may adversely affect the Company's earnings in the future.

                                    BUSINESS
 
     Renal Care Group is a specialized provider of nephrology services to
patients with kidney disease, including patients suffering from chronic kidney
failure, also known as end-stage renal disease. The Company provides dialysis
and ancillary services to approximately 5,000 patients through 77 outpatient
dialysis centers in 12 states and manages an additional eight dialysis centers
in five states in affiliation with leading medical centers such as Vanderbilt
University Medical Center and The Cleveland Clinic Foundation. In addition to
its outpatient dialysis center operations, Renal Care Group provides acute
dialysis services through contractual relationships with 42 hospitals,
staff-assisted dialysis services to 37 skilled nursing facilities and physician
practice management services to 16 of the 59 nephrologists who are affiliated
with the Company's outpatient dialysis centers.
 
     Renal Care Group was formed by leading nephrologists with the objective of
creating an entity with the clinical and financial capability to manage the full
range of care for ESRD patients on a cost-effective basis. The Company is
working in conjunction with its affiliated physicians to develop fully
integrated nephrology networks that will implement clinical protocols designed
to improve outcomes and reduce costly medical complications associated with
ESRD.
 
     According to HCFA, there were in excess of 2,800 dialysis centers in the
United States at the end of 1995. The Company believes that approximately 38%
were owned by multi-center dialysis companies, 32% were owned by independent
physicians and 30% were hospital-based centers. Although numerous nephrology
groups have in the past sold their dialysis centers to entities engaged in the
business of owning and operating such facilities, the Company believes that many
nephrology groups recognize the need to affiliate with an entity having broader
capabilities that can also provide clinical, financial and business expertise to
help them manage the increasingly complex and time-consuming aspects of both
their dialysis center operations and their nephrology practices. In addition,
many hospitals are motivated to sell or outsource management of their dialysis
facilities as they refocus their resources on their core business in response to
increasing competitive pressures. As a result of these and other factors, the
dialysis services industry is undergoing rapid consolidation.
 
INDUSTRY OVERVIEW
 
  End-Stage Renal Disease
 
     ESRD is the state of advanced renal impairment that is irreversible and
lethal unless treated. This condition is most commonly a result of complications
associated with diabetes, hypertension, certain renal and hereditary diseases,
old age and other factors. In order to sustain life, individuals with ESRD
require either dialysis for the remainder of their lives or successful kidney
transplantation.
 
     According to the USRDS, the total estimated direct medical charges for ESRD
exceeded $11.1 billion during 1994. Of the total direct medical charges for
ESRD, approximately $8.3 billion was paid by the federal government through the
Medicare program. As a result of legislation enacted in 1972, the federal
government provides Medicare funding for patients who are diagnosed with ESRD
regardless of their age or financial circumstances.
 
     Based on Medicare ESRD enrollment data published by HCFA, the number of
ESRD patients in the United States requiring dialysis treatments has grown from
approximately 66,000 at the end of 1982 to approximately 200,000 at the end of
1995. Based on USRDS data, the ESRD incidence rate among Medicare-eligible
patients for all age groups was approximately 219 patients per million in 1993
as compared to 111 patients per million in 1984. Furthermore, USRDS data
indicates that the incidence rate in patients ages 65 to 74 increased 130% from
1984 to 1993, and in patients ages 75 and older the incidence rate increased
189% over the same period.
 
     The Company attributes the growth in the number of ESRD patients
principally to the aging of the general population and the improved treatment
and increased survival rate of patients with diabetes, hypertension and other
illnesses that lead to ESRD. Moreover, improved dialysis technology has enabled
older patients and those who previously could not tolerate dialysis due to other
illnesses to benefit from this treatment.

  Treatment Options for End-Stage Renal Disease
 
     Currently, the three treatment options for ESRD are (i) hemodialysis, which
is performed either in a hospital setting, an outpatient facility or a patient's
home, (ii) peritoneal dialysis, which is generally performed in the patient's
home, and (iii) kidney transplant surgery. According to HCFA data, in 1995
approximately 83% of patients on dialysis in the United States received
outpatient hemodialysis treatment and approximately 17% received hemodialysis or
peritoneal dialysis in their homes.
 
     - Hemodialysis is the most common form of ESRD treatment and is generally
      performed either in a freestanding center or in a hospital. The process of
      hemodialysis uses a dialyzer, essentially an artificial kidney, to remove
      certain toxins, fluid and chemicals from the patient's blood and a device
      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 chambers. While the blood is circulated
      through one chamber, a pre-mixed dialysis fluid is circulated through the
      adjacent chamber. The toxins and excess fluid contained in the blood cross
      the membrane into the dialysis fluid. Hemodialysis treatment usually
      requires approximately four hours and is administered three times per week
      for the life of the patient pursuant to a nephrologist's plan of care.
 
     - Peritoneal dialysis is generally performed by the patient at home and
      uses the patient's peritoneal, or abdominal, cavity to eliminate fluids
      and toxins in the patient's blood. Although there are several variations
      of peritoneal dialysis, continuous ambulatory peritoneal dialysis ("CAPD")
      and continuous cyclic peritoneal dialysis ("CCPD") are the most common.
      CAPD uses a sterile dialysis solution which is introduced through a
      surgically implanted catheter into the patient's peritoneal cavity. Toxins
      in the blood continuously cross the peritoneal membrane into the dialysis
      solution. After several hours, the patient drains the used solution and
      replaces it with fresh solution. CCPD is performed in a manner similar to
      CAPD, but utilizes a mechanical device to cycle dialysis solution through
      the peritoneal membrane while the patient is sleeping or at rest. Patients
      treated at home are monitored monthly either through a visit from a staff
      person from a designated outpatient center or by the patient visiting the
      center.
 
     - Kidney transplantation, when successful, is the most desirable form of
      therapeutic intervention. However, the shortage of suitable donors
      severely limits the availability of this surgical procedure as a treatment
      option. Approximately 6% of patients with ESRD undergo kidney
      transplantation. Typically, transplant surgery is performed by transplant
      surgeons and not nephrologists.
 
  Ancillary Services
 
     Nephrologists provide ancillary services to ESRD patients, the most
significant of which is the administration of EPO. EPO is a bio-engineered
protein that mimics a hormone found in a normal kidney by stimulating the
production of red blood cells. EPO is utilized in connection with all forms of
dialysis to treat anemia, a medical complication experienced by almost all ESRD
patients. EPO reduces or eliminates the need for blood transfusions in these
patients. Other ancillary services provided by nephrologists to or in connection
with ESRD patients may include but are not limited to (i) certain laboratory
tests required by Medicare to determine the effectiveness of dialysis
treatments, (ii) intradialytic parenteral nutrition ("IDPN"), which are
nutrients added to a patient's blood during hemodialysis, (iii) studies to test
the degree of a patient's bone deterioration, an ESRD complication, (iv)
electrocardiograms, (v) nerve conduction studies to test for deterioration of a
patient's nerves, another ESRD complication, (vi) Doppler flow testing for the
effectiveness of the patient's vascular access for dialysis, and (vii) blood
transfusions.
 
  Nephrology Practice
 
     Caring for ESRD patients is the primary clinical activity of nephrologists.
Other clinical activities of a nephrologist include the post-surgical care of
kidney transplant patients, the diagnosis and treatment of kidney diseases in
patients who are at risk for developing ESRD, and the diagnosis, treatment, and
management of clinical disorders including hypertension, kidney stones and
autoimmune diseases. Because of the complexity involved in treating patients
with chronic kidney disease, the nephrologist typically assumes the role of
primary
 
                                       24
<PAGE>   26
 
care physician for the ESRD patient. The Company believes that while some
nephrologists practice independently or are members of multi-specialty groups,
most nephrologists practice in small single-specialty groups. Nephrology groups
typically provide services in relatively large geographic areas, and it is
common for a major part of a metropolitan area to be served by a single
nephrology group. Most nephrologists also have a significant office practice and
consult on numerous hospitalized patients who are not on dialysis. A
nephrologist typically derives income from services rendered (i) during office
visits, (ii) for the treatment of patients in acute care hospitals and (iii) for
the treatment of patients receiving dialysis services. Medicare reimburses
nephrologists based on a fixed fee per month for outpatient services rendered in
treating ESRD patients and based on designated rate schedules for services to
ESRD patients who are hospitalized.
 
STRATEGY
 
     Renal Care Group's objective is to develop fully integrated nephrology
provider networks to assume and manage the clinical and financial risk
associated with providing renal disease management services on a capitated
basis. The Company seeks to achieve this objective by (i) acquiring, developing
and managing outpatient and university-based dialysis centers, (ii) integrating
its dialysis centers with affiliated nephrology practices, (iii) developing a
protocol-driven ESRD management model to enhance clinical outcomes and (iv)
providing an appropriate range of ancillary services to ESRD patients. The
Company believes an integrated network of nephrologists and dialysis centers,
combined with the Company's clinical expertise, management experience and access
to capital, will provide significant advantages to patients and third-party
payors by improving the quality of care while reducing the overall costs
associated with treating patients with all forms of kidney disease, including
those who have ESRD. Following is a discussion of the key components of the
Company's growth strategy.
 
  Acquire, Develop and Manage Outpatient and University-Based Dialysis Centers
 
     Renal Care Group believes that the acquisition and development of dialysis
centers is the first step in the development of a fully integrated nephrology
management company. When considering the acquisition or development of dialysis
centers, the Company's most important criteria are the ability to secure
significant market share, the availability of one or more leading nephrologists
to serve as medical director(s) of the center and the quality of care provided
by such center. In addition, the Company also considers factors such as
financial results and the potential financial impact on the Company, the growth
potential and demographic characteristics of the market, the convenience of the
location for patients and physicians, the condition of the center and its
equipment, the local labor conditions, and the availability of qualified
clinical personnel.
 
     The Company's acquisition and development strategy contains two primary
elements. First, physicians affiliated with the Company explore acquisition
opportunities from among their contacts with nephrologist owners of dialysis
centers throughout the country. Second, the Company seeks to acquire and/or
develop dialysis centers in underserved or expanding population areas that are
contiguous to the present markets of the Company.
 
     In addition to acquiring and developing freestanding centers, the Company
develops and operates dialysis centers by entering into arrangements with
leading hospitals and university medical dialysis programs for the management of
ESRD care. The Company currently has inpatient dialysis contracts with 42
hospitals. The Company also manages dialysis programs in affiliation with
leading medical centers such as Vanderbilt University Medical Center and The
Cleveland Clinic Foundation. The Company believes that contracts with medical
centers and university dialysis programs provide access to relevant studies and
other research that will enable the Company to determine measurable ESRD
outcomes and thereby enhance both the quality and cost-effectiveness of care. In
addition, the Company believes such affiliations may expand relationships with
highly qualified independent nephrologists and result in increased opportunities
to acquire the dialysis centers of such nephrologists. See
"Business -- Operations."
 
                                       25
<PAGE>   27
 
  Integrate Dialysis Centers with Nephrology Practices
 
     Renal Care Group intends to integrate its dialysis centers with affiliated
nephrologists into regional delivery networks. In order to facilitate this
integration, the Company attempts to acquire or enter into management agreements
with the practices of affiliated nephrologists. The Company believes that
increased managed care, capitation and other forms of risk-sharing between
payors and providers will require providers to offer integrated nephrology
services through a network of dialysis centers and nephrology practices. The
Company believes such arrangements will enable nephrologists to coordinate and
manage the delivery of care to ESRD patients more effectively. In addition, the
Company believes that a large, well-managed and well-capitalized nephrology
group will have an advantage in recruiting newly-trained nephrologists.
 
     The Company believes that nephrology groups increasingly are recognizing
the need for professional, management and clinical services to assist in the
management of their practices and in the development and administration of the
most effective care for ESRD patients. The Company believes that nephrologists
typically practice independently or in small groups and lack (i) the capital to
expand or develop information systems, (ii) the ability to realize economies of
scale to manage resources or negotiate with suppliers, and (iii) the ability to
develop cost-effective clinical outcome strategies critical to contracting with
managed care payors.
 
     The Company currently manages the practices of 16 nephrologists who have
practice privileges at 15 of its centers. In addition, the Company has certain
rights of first refusal with respect to any proposed arrangement with a third
party for the sale or management of the practices of 27 additional nephrologists
who have practice privileges at 34 of its centers. The Company provides billing,
information systems and general administrative services to the nephrology
practices it manages and is paid a management fee for such services. See
"Business -- Nephrology Practice Management."
 
  Develop a Protocol-Driven ESRD Management Model to Enhance Clinical Outcomes
 
     Renal Care Group believes that the provision of high quality care to ESRD
patients significantly reduces the aggregate costs associated with ESRD by
decreasing the number of days an ESRD patient spends in the hospital and thereby
limiting the most expensive component of ESRD health care. The Company believes
that access to medical research regarding causes and effects of ESRD, including
causes and lengths of hospitalization and resulting gross and standardized
mortality rates, and different types of treatment outcomes, is crucial to the
successful management of ESRD. The Company believes that its affiliation with
university-based dialysis programs provides it with access to such outcomes
research and to clinically advanced treatment protocols. For example, according
to data published by the USRDS, during 1993, the average number of days spent in
a hospital by dialysis patients less than 65 years of age was 11.5, and for
patients older than 65 years was 12.0. Similarly, the USRDS calculated the
overall mortality rate of dialysis patients during the first year of therapy
(starting in the 91st day after initiation of therapy) to be 25.7% in 1993.
Treatment protocols designed to address such issues as adequacy of dialysis,
nutrition, and management of hemodialysis access complications can significantly
improve mortality and decrease hospitalization rates. The Company believes that
the protocols it has implemented in the dialysis program at Vanderbilt have been
effective in maintaining an overall mortality rate of approximately one-half of
the national average and in reducing the average hospitalization rate for all
age groups to less than 10 days a year per patient. The Company is in the
process of implementing clinical protocols at its centers and believes that such
implementation will enhance outcomes and improve operating efficiencies.
 
  Provide an Appropriate Range of Ancillary Services
 
     Renal Care Group provides a variety of ancillary services necessary for the
treatment of ESRD patients, the most significant of which is the administration
of EPO. EPO is a bio-engineered 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. Other
ancillary services offered by the Company include studies to test the degree of
bone deterioration; electrocardiograms; nerve conduction studies to test the
degree of deterioration of nerves; Doppler flow testing to test the
effectiveness of the patient's vascular
 
                                       26
<PAGE>   28
 
access for dialysis; and blood transfusions. The Company estimates that less
than 0.5% of its net revenue for the six months ended June 30, 1996 was
reimbursement for the administration of IDPN.
 
     In addition, the Company requires the services of a clinical laboratory to
perform certain blood testing in connection with dialysis treatment. Pursuant to
a management contract with Kidney Care, the Company provides certain management
services to and uses as a reference lab a full service laboratory owned by
Kidney Care with capacity to perform clinical testing services for up to
approximately 7,000 ESRD patients. Due to certain regulatory constraints, the
Company was not able to acquire the laboratory at the time of the Combination,
but has an option to purchase the assets of such laboratory expiring in April
1999, by which time the Company expects to be in a position to exercise the
option if it so desires. See "Certain Transactions" and "Business -- Government
Regulation."
 
OPERATIONS
 
  Location, Capacity and Use of Facilities
 
     Renal Care Group operates 77 outpatient dialysis centers in 12 states with
59 affiliated nephrologists and 1,111 certified dialysis stations, excluding
eight centers managed by the Company. The Company leases 58 centers and owns 19
centers. The Company also provides inpatient dialysis services to 42 acute care
hospitals and 37 skilled nursing facilities. Excluding managed centers, 625,413
and 331,280 hemodialysis treatments were provided at the Company's facilities
during the year ended December 31, 1995 and the six months ended June 30, 1996,
respectively.
 
     The Company estimates that its centers were operating at approximately 64%
of capacity as of June 30, 1996, based on the assumption that a dialysis center
is able to provide up to three treatments a day per station, six days a week.
The Company believes it may increase the number of dialysis treatments at its
centers without making additional capital expenditures.
 
  Operation of Facilities
 
     Renal Care Group's dialysis centers provide outpatient hemodialysis and
related services to ESRD patients in a convenient setting. A majority of the
Company's centers utilize volumetric dialysis equipment that accommodates high
flux and high efficiency dialysis treatments. In addition to dialysis stations,
the Company's centers generally contain a nurses' station, a patient waiting
area, examination rooms, a supply room, a water treatment space to purify water
used in hemodialysis treatments, a dialyzer reprocessing room, staff work areas,
offices, and a staff lounge. Many of the Company's centers also have a
designated area for training patients in home dialysis and also offer certain
amenities for the patients.
 
     In accordance with conditions for participation in the Medicare ESRD
program, each of the Company's centers is supervised by a qualified Medical
Director. Each center is managed by an administrator, typically a registered
nurse, who is responsible for the day-to-day operations of the center and its
staff. The staff of each center typically includes registered nurses, licensed
practical or vocational nurses, patient care technicians, social workers,
registered dietitians, a unit clerk, and biomedical equipment technicians. Each
center is staffed in a manner that allows the number of personnel to be adjusted
according to the number of patients receiving treatments.
 
  Home Dialysis
 
     All of Renal Care Group's centers offer various forms of peritoneal and
home hemodialysis, primarily CAPD or CCPD. As of June 30, 1996, approximately
13% of the patients treated by the Company received home dialysis. The Company's
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. The Company intends to expand its
home dialysis program, which the Company believes is important to the
development of a fully integrated nephrology services company.

  Hospital and Skilled Nursing Facility Care
 
     Certain of Renal Care Group's centers provide dialysis services through
contracts with 42 hospitals located within their respective service areas. Under
these contracts, the Company's centers typically provide equipment, supplies and
personnel required to perform hemodialysis and peritoneal dialysis in connection
with the hospital's inpatient services. Such inpatient dialysis services are
required for patients with acute renal failure resulting from accidents, medical
and surgical complications, patients in the early stage of renal failure and
ESRD patients who require hospitalization for other reasons. The terms of these
contracts are individually negotiated and vary by contract. Most of the
Company's hospital contracts specify predetermined fees per dialysis treatment,
although the Company believes that such fees may be subject to negotiation in
the future as the provision of health care services becomes increasingly
influenced by managed care and subject to capitated arrangements.
 
     The Company also provides staff-assisted dialysis services to 37 skilled
nursing facilities in the Phoenix metropolitan area. A central office dispatches
equipment, supplies and personnel required to perform dialysis treatments in
connection with the extended care services of skilled nursing facilities.
 
  University Division
 
     Renal Care Group currently manages the dialysis programs at Vanderbilt
University Medical Center, The Cleveland Clinic Foundation and Case Western
Reserve University, provides home dialysis services for a group of patients at
the University of Arkansas, provides consulting services to the University of
Michigan Medical Center regarding its dialysis program and is developing a
dialysis center for the University of Louisville. The Company intends to expand
its university management program and is currently in various stages of
discussions with a number of university-based dialysis programs. In addition,
the Company also intends to acquire or develop university-based dialysis
centers. The Company believes that its affiliation with leading nephrology
groups will enhance its ability to attract and maintain agreements to manage the
dialysis programs of university medical centers. Furthermore, the Company
expects that affiliation with university medical centers will provide a greater
number of patients, including the potential for the development of new centers
and access to highly qualified Medical Directors and outcomes research.
 
  Relationships with Referral Sources; Medical Directors
 
     A key factor in the success of a dialysis center is its relationship with
local nephrologists. An ESRD patient generally seeks treatment at a center where
the patient's nephrologist has practice privileges. Consequently, Renal Care
Group relies on its ability to attract and to meet the needs of referring
nephrologists in order to receive and gain new referrals.
 
     The Company has engaged practicing, board-eligible or board-certified
nephrologists to serve as Medical Directors for each of its centers. Each of the
Company's Medical Directors provides services pursuant to an independent
contractor agreement between the Company and the physician or his or her
professional practice group. Medical Directors' responsibilities primarily
consist of the administration and monitoring of the Company's patient care
policies, including patient education, administration of dialysis treatment,
development and training programs and assessment of all patients. Coordination
of the delivery of care is important in maintaining ESRD patients' general level
of health and in avoiding medical complications that might necessitate
hospitalization.
 
     The Company typically enters into Medical Director agreements with
nephrologists at each of its centers containing terms of seven years with
three-year renewal options. The Company's Medical Director agreements typically
provide for its Medical Directors to be paid fees for their supervisory services
and include non-competition clauses with specific limitations on their ability
to compete with the Company for certain periods of time and in certain
geographic areas. In consideration for such non-competition agreements, the
Company has granted options to purchase shares of Common Stock to the physicians
serving as Medical Directors or their professional practice groups.
 
                                       28
<PAGE>   30
 
  Nephrology Practice Management
 
     Renal Care Group currently manages the practices of 16 physician
nephrologists pursuant to the terms of management service arrangements. Under
these arrangements, the Company typically provides to the physicians, in
exchange for a management fee, certain equipment, supplies and administrative
services, including billing, collection, accounting, human resources and
information systems. Each physician retains exclusive control of the provision
of medical services to his or her patients.
 
QUALITY ASSURANCE
 
     In order to optimize therapy and improve outcomes, Renal Care Group
establishes and maintains quality criteria for its clinical operations, monitors
patient outcomes in all of its centers, utilizes a Medical Advisory Board to
develop a protocal-driven clinical management model and involves its patients in
their own care.
 
  Quality Criteria
 
     Renal Care Group actively involves its Medical Advisory Board in the
establishment of quality criteria for both owned centers and its acquisition
candidates. Regular evaluation of the prescribed dialysis treatments and the key
physiological parameters of patients constitutes part of the continuous quality
improvement that is the Company's primary clinical objective. The Company
employs a registered nurse as a corporate Quality Assurance Coordinator to
oversee the Company's continuous quality assurance program. In addition, each
center has a quality assurance committee that typically includes the Medical
Director, the center administrator and nurses, as well as other technical
personnel. This committee meets regularly to monitor the quality of care in the
center and to assure compliance with applicable regulations.
 
  Outcomes Data
 
     Renal Care Group believes that an important factor in the successful
management of ESRD is access to a broad database of treatment-specific outcomes
information from which clinical pathways may be defined. The Quality Assurance
Coordinator oversees the collection of patient outcomes and cost data in the
Company's centers to assist in implementing clinical pathways to enhance patient
outcomes while reducing the cost of care. Management believes that the
implementation of such clinical pathways is necessary to improve the overall
quality and operating efficiencies of its dialysis centers and to contract more
effectively with payors in a health care environment increasingly influenced by
managed care.
 
  Medical Advisory Board
 
     Renal Care Group's Medical Advisory Board meets quarterly to monitor the
development and implementation of clinical protocols and to review patient
outcomes. The Medical Advisory Board is chaired by Raymond Hakim, M.D., Ph.D.,
the Company's Chief Medical Officer, and is composed of affiliated
nephrologists. In addition, the Medical Advisory Board is responsible for
establishing, implementing and monitoring the Company's quality assurance
policies and procedures, identifying therapy deficiencies, and evaluating
technological changes. The Medical Advisory Board's principal task is the
development of a protocol-driven clinical management model that will enable the
Company to manage effectively the financial risk associated with ESRD
capitation.
 
  Patient Involvement
 
     The Company also attempts to ensure quality care by instructing all ESRD
patients before and after the initiation of dialytic therapy on methods for
participating in their own care to the fullest extent possible. In addition, in
some of the Company's centers, "self-care" units are formed in which
self-reliance is fostered through instruction and support.

</TABLE>
 
     The Social Security Act (the "Act") provides for Medicare coverage for
certain individuals who are medically determined to have ESRD. Once an
individual is medically determined to have ESRD, the Act specifies that one of
two conditions must be met before entitlement begins: (i) a regular course of
dialysis must begin, or (ii) a kidney transplant must be performed. The Act
provides that entitlement begins the third month after the month in which a
regular course of renal dialysis is initiated. ESRD is currently defined in
federal regulations as that stage of kidney impairment that appears irreversible
and permanent and requires a regular course of dialysis or kidney
transplantation to maintain life.
 
     Under the Medicare ESRD program, the reimbursement rates per treatment are
fixed but have been adjusted from time to time by legislation. Although this
form of reimbursement limits the allowable charge per treatment, it provides the
Company with predictable and recurring per treatment revenue. The Medicare
composite rate, set by HCFA, governs the Medicare reimbursement available for a
designated group of dialysis services, including the dialysis treatment,
supplies used for such treatment, certain laboratory tests and medications. The
Medicare composite rate is subject to regional differences based on certain
factors, including regional differences in wages. Certain other services and
drugs are eligible for separate reimbursement under Medicare and are not part of
the composite rate, including certain drugs such as EPO and certain physician
ordered tests provided to dialysis patients. The Company generally submits
Medicare claims monthly and is usually paid within 30 days of the submission.
 
  Medicare Eligibility
 
     Set forth below are summaries of the general requirements for participation
in the Medicare ESRD program:
 
     - Medicare generally covers those who are ages 65 and over, as well as
      those who are under age 65 and who have been medically determined to have
      ESRD. However, Medicare coverage is secondary for some patients who have
      qualifying employer group health insurance.
 
     - For patients eligible for Medicare based solely on ESRD (generally, those
      under age 65), Medicare coverage begins three months after the month in
      which the patient begins dialysis. During this three-month waiting period,
      Medicaid (if the patient is eligible), private insurance, or the patient
      is responsible for payment for dialysis services. This waiting period is
      waived for individuals who participate in a self-care dialysis training
      program.
 
     - For ESRD patients under age 65 who have any employer group health
      insurance coverage (regardless of the size of the employer or the
      individual's employment status), Medicare coverage is secondary to the
      employer coverage during the 18-month period following the establishment
      of Medicare eligibility based on ESRD. Medicare continues to be secondary
      regardless of whether the individual becomes eligible for Medicare based
      on age or disability before the expiration of the 18 months.
 
     - During the period of secondary coverage, the employer group health plan
      is responsible for paying primary benefits at its negotiated rate or, in
      the absence of such a rate, at the Company's usual and customary rates.
      Medicare generally pays the difference between what the employer group
      health plan paid and the gross amount payable by Medicare.
 
                                       30
<PAGE>   32
 
     - For patients over ages 65 for whom Medicare already is the primary payor
      and who later develop ESRD, Medicare remains the primary payor. (Some
      group health coverage does not render Medicare coverage secondary for
      beneficiaries eligible for Medicare based on age or disability.) However,
      if the patient's employer group health coverage already was primary to
      Medicare (based on the size of the employer and the patient's employment
      status), then Medicare remains secondary for the 18-month period.
 
     - When Medicare is the primary payor, it reimburses 80% of the amount set
      by the Medicare prospective reimbursement system for each treatment. The
      beneficiary is responsible for the remaining 20%, as well as any unmet
      Medicare deductible amount, although Medicare supplemental insurance,
      Medicaid, or other private health insurance may pay on the beneficiary's
      behalf.
 
     Following amendments in 1993 to the Medicare Secondary Payor ("MSP")
provisions, HCFA required employer group health plans to serve as the primary
payor during the 18-month period in situations where the beneficiary was
entitled to Medicare Benefits on the basis of both age and ESRD. In April 1995,
HCFA revised its interpretation of the 1993 MSP amendments to require Medicare
to serve as primary payor for the 18 month period only where employer coverage
was already secondary to Medicare for individuals eligible for Medicare benefits
on the basis of both age and ESRD. This change eliminates for some
dually-eligible individuals the 18-month period commencing 90 days after the
start of treatment during which the employer coverage would serve as primary
payor source and reimburse the Company at a rate that the Company believes is
higher than Medicare. Furthermore, HCFA also announced that the revised
interpretation would apply retroactively to August 1993 and, as a result,
amounts collected from employer-based group health plans as primary payors
between August 1993 and April 1995 were to be refunded if the plan was not
already serving as primary payor. In June 1995, the United States District Court
for the District of Columbia issued a preliminary injunction prohibiting HCFA
from applying this revised interpretation retroactively to August 1993, although
a final ruling on the issue has not yet been issued by the court. The Company
has established reserves for the retroactive application of the revised HCFA
interpretation and believes that the amount of such reserves is adequate.
 
  Medicare Reimbursement Rates
 
     The Medicare composite rate for outpatient dialysis services currently
averages $126 per treatment and may vary depending on regional wage differences.
Medicare reimbursement rates are adjusted periodically based on certain factors,
including legislation and executive and congressional budget reduction and
control processes, inflation and costs incurred in rendering the services, but
in the past have had little relationship to the cost of conducting business.
 
     The Medicare ESRD composite reimbursement rate was unchanged from
commencement of the program in 1972 until 1983. From 1983 through December 1990,
numerous Congressional actions resulted in net reductions of the average
composite reimbursement rate from a fixed fee of $138 per treatment in 1983 to
approximately $125 per treatment in 1986. Congress increased the ESRD composite
reimbursement rate, effective January 1991, resulting in an average rate of $126
per treatment.
 
     The Medicare ESRD composite reimbursement rate has been the subject of a
number of reports and studies. In April 1991, the Institute of Medicine, an
organization chartered by the National Academy of Sciences and an advisor to the
federal government, released a report recommending that the composite rate be
adjusted for the effects of inflation. In March 1996, the Prospective Payment
Assessment Commission ("PROPAC") recommended that the ESRD composite
reimbursement rate be increased by 2.0% for freestanding facilities for fiscal
year 1997. In August 1996, and in response to the March 1996 report of PROPAC,
HCFA announced that an increase in the composite rate may be appropriate within
the next few years. In making this announcement HCFA also stated that any rate
increase must be considered in the context of Medicare budgetary concerns.
Nevertheless, HCFA stated that it may recommend an update to the composite rate
for fiscal year 1998. In January 1996, HCFA announced a three-year demonstration
project involving the enrollment of ESRD patients in managed care organizations.
The demonstration project would adjust payment rates based upon treatment
status, age groups, and the cause of renal failure. Based upon the
 
                                       31
<PAGE>   33
 
results of the demonstration project, HCFA has stated it would make
recommendations to Congress concerning the appropriateness of paying for ESRD
services on a capitated basis. Congress is not required to implement these
recommendations and could either raise or lower the reimbursement rate. During
the last congressional session, there were various proposals for the reform of
numerous aspects of Medicare. The Company is unable to predict what, if any,
future changes may occur in the Medicare composite reimbursement rate. Any
reductions in the Medicare composite reimbursement rate could have a material
adverse effect on the Company's results of operations, financial condition and
business.
 
     From June 1989 through December 1990, the Medicare ESRD program added $40
per administration of EPO to the dialysis center's allowable composite rate for
dosages of up to 9,999 units per administration. For higher dosages, an
additional $30 per treatment was allowed. Effective January 1991, the Medicare
allowable prescribed rate for EPO was changed to $11 per 1,000 units, rounded to
the nearest 100 units. Subsequently, legislation was enacted to reduce the
Medicare prescribed rate for EPO by $1 to $10 per 1,000 units for administration
of EPO in 1994. For subsequent periods, the Secretary of the Department of
Health and Human Services ("HHS") is authorized to determine an appropriate
rate, which currently is $10 per 1,000 units administered.
 
  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 (e.g., oral
medications) that are not covered by Medicare. State regulations generally
follow Medicare reimbursement levels and coverages without any coinsurance
amounts. Certain states, however, require beneficiaries to pay a monthly share
of the cost based upon levels of income or assets. The Company is a licensed
ESRD Medicaid provider in all states in which it does business.
 
  Private Reimbursement/Acute Care Contracts
 
     The Company receives reimbursement from private payors for ESRD treatments
prior to Medicare becoming a patient's primary payor at rates significantly
higher than the per treatment rate set by Medicare. After Medicare becomes a
patient's primary payor, private secondary payors generally reimburse the
Company for 20% of the Medicare per treatment rate. The Company has negotiated
managed care contracts with certain payors at rates that are higher than the
Medicare rate. The Company also receives payments from hospitals under 21 acute
care contracts at rates significantly higher than the Medicare composite rate.
 
GOVERNMENT REGULATION
 
  General
 
     The Company's dialysis center operations are subject to extensive
governmental regulation at the federal, state and local levels. These
regulations require the Company to meet various standards relating to, among
other things, the management of centers, personnel, maintenance of proper
records, equipment and quality assurance programs. The dialysis centers are
subject to periodic inspection by state agencies and other governmental
authorities to determine if the premises, equipment, personnel and patient care
meet applicable standards. To receive Medicare reimbursement, the Company's
dialysis centers must be certified by HCFA as meeting certain Medicare
conditions of coverage. All of the Company's dialysis centers are so certified.
HCFA has announced that it is in the process of revising the current Medicare
Conditions of Coverage for ESRD services. The Company is unable to predict what,
if any, future changes may occur in the Medicare Conditions of Coverage for ESRD
facilities.
 
     Any changes to the Medicare Conditions of Coverage, or any loss by the
Company of its federal certifications, its authorization to participate in the
Medicare or Medicaid programs or its licenses under the laws of any state or
other governmental authority from which a substantial portion of its revenues is
derived or a change resulting from health care reform reducing dialysis
reimbursement or reducing or eliminating
 
                                       32
<PAGE>   34
 
coverage for dialysis services would have a material adverse effect on the
Company's operations, revenues and net earnings. To date, the Company and its
subsidiaries have maintained their licenses and their Medicare and Medicaid
authorizations. The Company believes that the health care services industry will
continue to be subject to intense regulation at the federal, state and local
levels, the scope and effect of which cannot be predicted. No assurance can be
given that the activities of the Company will not be reviewed and challenged by
government regulators or that health care reform will not result in a material
adverse change to the Company.
 
     Furthermore, the Company potentially could be held responsible for actions
previously taken by entities it has acquired. As part of its announced
regulatory agenda for 1996, HHS intends to issue a proposed rule that would
automatically assign to the new owner of a Medicare provider or supplier
liability for any Medicare overpayments, violations, or sanctions incurred by or
imposed on, the previous owner. There can be no assurance that previous
operating practices of the Company's acquisitions will not be reviewed and
challenged by government regulators or that the Company will not be liable for
such practices.
 
  Fraud and Abuse
 
     The Company's operations are subject to the illegal remuneration provisions
of the Social Security Act (sometimes referred to as the "anti-kickback"
statute) and similar state laws that impose criminal and civil sanctions on
persons who knowingly and willfully solicit, offer, receive or pay any
remuneration, whether directly or indirectly, in return for, or to induce, the
referral of a patient for treatment, or, among other things, the ordering,
purchasing, or leasing, of items or services that may be paid for in whole or in
part by Medicare, Medicaid or similar state programs.
 
     Federal enforcement officials may attempt to impose civil false claims
liability with respect to claims resulting from an anti-kickback violation.
Violations of the federal anti-kickback statute are punishable by criminal
penalties, including imprisonment, fines and exclusion of the provider from
future participation in the Medicare or Medicaid programs. Civil penalties for
violations of the federal anti-kickback statute are punishable by criminal
penalties, including imprisonment, fines and exclusion of the provider from
future participation in the Medicare or Medicaid programs. Civil suspension from
participation in Medicare or Medicaid for anti-kickback violations also can be
imposed through an administrative process, without the imposition of civil
monetary penalties. Some state statutes also include criminal penalties. While
the federal anti-kickback statute expressly prohibits transactions that have
traditionally had criminal implications, such as kickbacks, rebates or bribes
for patient referrals, its language has been construed broadly and has not been
limited to such obviously wrongful transactions. Court decisions state that,
under certain circumstances, the statute is also violated when one purpose (as
opposed to the "primary" or a "material" purpose) of a payment is to induce
referrals. Congress has frequently considered federal legislation that would
expand the federal anti-kickback statute to include the same broad prohibitions
regardless of payer source. In fact, effective January 1, 1997, the Health
Insurance Portability and Accountability Act of 1996 expands the anti-kickback
statute to certain other "Federal Health Care Programs," such as CHAMPUS.
 
     In July 1991 and in November 1992, the Secretary of HHS published
regulations that create exceptions or "safe harbors" for certain business
transactions. Transactions that satisfy the criteria under applicable safe
harbors will be deemed not to violate the federal anti-kickback statute.
Transactions that do not satisfy all elements of a relevant safe harbor do not
necessarily violate the statute, although such transactions may be subject to
scrutiny by enforcement agencies. The Company seeks to structure its various
business arrangements to satisfy as many safe harbor elements as possible under
the circumstances, although not all of the Company's arrangements satisfy all of
the elements of a safe harbor. Although the Company has never been challenged
under any anti-kickback statute and the Company believes it has a reasonable
basis for concluding that it complies in all material respects with the federal
anti-kickback statute and all other applicable related laws and regulations,
there can be no assurance that the Office of the Inspector General (the "OIG")
within HHS or other governmental agency will not take a contrary position or
that the Company will not be required to change its practices in a manner which
will cause, or will not otherwise experience, a material adverse effect as a
result of any such challenge or any sanction which might be imposed.
 
                                       33
<PAGE>   35
 
     In July 1994, the Secretary of HHS proposed a rule that would modify the
original set of safe harbor provisions to give greater clarity to the rule
making's original intent. The proposed rule would make changes to the safe
harbors on personal services and management contracts, small entity investment
interests and space rentals, among others. The Company does not believe that its
current operations, as set forth above, would change if the proposed rule were
adopted in the form proposed. However, the Company cannot predict the outcome of
the rule making process or whether changes in the safe harbors rule will affect
the Company's position with respect to the federal anti-kickback statute.
 
     Nephrologist Ownership.  At the closing of the Combination and the
Company's recent mergers, shares of Common Stock were issued to certain
nephrologist owners of the facilities. In addition, pursuant to the terms of the
Company's agreements with its Medical Directors or their professional practice
groups, the Company pays fees for medical director services and has granted
options to purchase shares of Common Stock to individual Medical Directors or
their respective practice groups. Because these physicians refer to the
Company's centers, the federal anti-kickback statute could be found to apply to
referrals by nephrologists to the Company's facilities. However, the Company
believes these ownership relationships are in material compliance with the
federal anti-kickback statute. Also, the Company believes that the value of
Common Stock issued and options granted to nephrologists have and will be
consistent with the fair market value of assets transferred to, or services
performed by such nephrologists for, the Company and there is no intent to
induce referrals to the Company's facilities. There is a safe harbor for certain
investments in large public companies, and the Company believes that there are
good arguments that its physician ownership relationships meet at least a
majority of the criteria for this safe harbor. However, these relationships do
not satisfy all of the criteria of a safe harbor and there can be no assurance
that these relationships will not subject the Company to investigation or
prosecution by enforcement agencies.
 
     Medical Director Relationships.  The Conditions of Coverage under the
Medicare ESRD program mandate that treatment at a dialysis center be under the
general supervision of a medical director who is a licensed 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 centers. The Company has engaged
Medical Directors at each of its centers under contracts with physicians,
nephrologists or group practices. The compensation of the Medical Directors and
other physicians under contract with the Company is separately negotiated and
generally depends upon competitive factors in the local market, the physician's
professional qualifications and responsibilities and the size and utilization of
the center or relevant program. The aggregate compensation of the Medical
Directors and other physicians under contract with the Company is generally
fixed in advance for periods of one year or more by written agreement and is set
to reflect the fair market value of the services rendered and does not take into
account the volume or value of patients referred to the Company's facilities.
Because in all cases the Medical Directors and the other physicians under
contract with the Company refer patients to the Company's centers, the federal
anti-kickback statute could be found to apply. However, the Company believes it
has a reasonable basis for concluding that its contractual arrangements with
these physicians are in material compliance with the federal anti-kickback
statute. In all instances, the Company seeks to comply with the requirements of
the personal services and management contract safe harbor when entering into
agreements or contracts with its Medical Directors and other physicians.
 
     Acute Dialysis Services.  Under the Company's acute inpatient dialysis
service arrangements, the Company agrees to provide a hospital with supervised
emergency or acute dialysis services, including qualified nursing and technical
personnel and technical services, and, in some cases, equipment. Because
physicians under contract with the Company may refer patients to hospitals with
which the company has an acute dialysis service arrangement, the federal
anti-kickback statute could be found to apply. However, the Company believes it
has a reasonable basis for concluding that its contractual arrangements with
hospitals for acute inpatient dialysis services are in material compliance with
the federal anti-kickback statute. In all instances, the company seeks to comply
with the requirements of the personal services and equipment lease safe harbors
when entering into agreements or contracts for acute inpatient dialysis
services.
 
     Certain Relationships with Laboratories, IDPN Suppliers, and
Hospitals.  The Company enters into arrangements for purposes of obtaining
laboratory services. Such services include testing currently reimbursed
 
                                       34
<PAGE>   36
 
under the Medicare composite rate, as well as testing reimbursed separately from
the Medicare composite rate. In October 1994, the OIG published a Special Fraud
Alert which stated that the federal anti-kickback statute could be violated when
a dialysis center obtains discounts from a laboratory for testing encompassed
within the Medicare composite rate in return for referring all or most of the
dialysis center's non-composite rate testing to the laboratory. In addition, the
Company enters into arrangements with suppliers of IDPN. In May 1993, the OIG
issued a report indicating its belief that many ESRD patients receive IDPN
despite not meeting Medicare coverage guidelines for the treatment. Furthermore,
in July 1993, the OIG issued a Management Advisory Report indicating that
"administration fees" paid by IDPN suppliers to dialysis centers for
administering IDPN to patients during dialysis could violate the federal
anti-kickback statute where the payments made to the dialysis centers are
unreasonably high (the report cited fees in the range of $30 per administration
as raising anti-kickback law questions). Moreover, the Company enters into acute
inpatient dialysis service arrangements under which the Company agrees to
provide a hospital with supervised emergency or acute inpatient dialysis
services, including qualified nursing and technical personnel and technical
services and, in some cases, equipment and supplies. Because physicians under
contract with the Company may refer patients to hospitals with which the Company
has an acute dialysis service arrangement, the federal anti-kickback statute
could be found to apply.
 
     The Company believes that the current arrangements of the Company with
nephrologist owners, medical directors, laboratories, IDPN suppliers, hospitals,
and other persons or entities who either refer patients to the Company's
dialysis centers or from whom the Company purchases items or services generally
are in material compliance with the federal anti-kickback statute. Specifically,
the Company believes that such arrangements now generally provide, and will
provide for reasonable compensation to or by the Company for the items and
services it buys from or furnishes to such persons or entities. Moreover, the
Company intends that IDPN therapy will be furnished in accordance with specified
utilization protocols consistent with Medicare coverage guidelines, and only to
patients for whom it is deemed medically necessary, as demonstrated by
physician-authorized Certificates of Medical Necessity. However, there can be no
assurance that the Company's future arrangements will not be challenged or
subject to sanctions for any of the Founding Companies' past arrangements. Any
such challenge or change, including any related sanctions which might be
assessed, could have a material adverse effect on the Company's operations, net
revenue and earnings.
 
  Stark II
 
     Provisions enacted as part of the Omnibus Budget Reconciliation Act of 1993
("Stark II") restrict physician referrals for certain designated health services
to entities with which a physician or an immediate family member has a
"financial relationship." The entity is prohibited from claiming payment under
the Medicare or Medicaid programs for services rendered pursuant to a prohibited
referral and is liable for the refund of amounts received pursuant to prohibited
claims. The entity also can incur civil penalties of up to $15,000 per improper
claim and can be excluded from participation in the Medicare or Medicaid
programs. Provisions enacted as part of the Omnibus Budget Reconciliation Act of
1989 ("Stark I") imposing comparable restrictions to clinical laboratory
services became effective in 1992. Stark II provisions applicable to "designated
health services" that may be relevant to the Company became effective in January
1995.
 
     A "financial relationship" under Stark II is defined as an ownership or
investment interest in, or a compensation arrangement between, the physician (or
an immediate family member) and the entity. The company has entered into
compensation agreements with its Medical Directors or their respective
professional practices. The Medical Directors or their professional practices
also will own shares, and options to purchase shares, of Common Stock.
Accordingly, the Medical Directors will have a "financial relationship" with the
company for purposes of Stark II.
 
     For purposes of Stark II, "designated health services" include, among other
things: clinical laboratory services; parenteral and enteral nutrients,
equipment and supplies, including IDPN; prosthetics; orthotics; prosthetic
devices; physical and occupational therapy services; outpatient prescription
drugs; durable medical equipment; and inpatient and outpatient hospital
services. Dialysis is not a designated health service under Stark II. However,
the Stark II definition of "designated health services" includes items and
services that are components of dialysis or that may be provided to a patient in
connection with dialysis, if such items and
 
                                       35
<PAGE>   37
 
services are considered separately rather than collectively as dialysis. Under
the final Stark I regulations published in August 1995, HCFA provided an
exception from Stark I for clinical laboratory services reimbursed under the
Medicare "composite rate" for dialysis. The Company believes it likely that,
when final Stark II regulations are published, they will contain a similar
exception for "designated health services" reimbursed under the composite rate.
However, there can be no assurance that HCFA will adopt such a position. Even if
the final Stark II regulations contain such an exception, the Company's
provision of, or arrangement and assumption of financial responsibility for,
outpatient prescription drugs, including EPO, enteral and parenteral nutrients,
such as IDPN, clinical laboratory services, center dialysis services and
supplies, home dialysis supplies and equipment, and services to hospital
inpatients and outpatients, includes services and items that are reimbursed
separate from the Medicare composite rate and therefore are likely to be
construed to be "designated health services" within the meaning of Stark II. In
addition, the Company obtains clinical laboratory services from the laboratory
that currently is operated by Kidney Care, a tax exempt entity under Section
501(c)(3) of the Internal Revenue Code. The Company holds an option to purchase
the assets of this laboratory. The Company has also entered into a management
agreement under which it provides certain management and administrative
services, equipment and technical support to the laboratory for a fee. The
Company believes, based on the fact that there is no direct or indirect
physician ownership of the laboratory and that the option relates only to the
assets of the laboratory (and not the entity that owns them or any earnings
therefrom) and, with respect to the management agreement, that the terms of the
contract with the laboratory comply with the material provisions of the personal
services and equipment and space lease exceptions under Stark II, that there are
sound arguments that the existence of the option and the management agreement
will not create an indirect ownership or compensation arrangement between the
laboratory and the Company's nephrologist owners or Medical Directors that would
prohibit the Company's dialysis centers from obtaining services from this
laboratory that are reimbursed separate from the Medicare composite rate in the
absence of a Stark II exception. However, there can be no assurance that HCFA or
the OIG would adopt or agree with this position.
 
     Although the Company has learned that HCFA officials responsible for
drafting implementing regulations for Stark II have tentatively taken the
informal position that administration of certain prescription drugs that would
not be needed but for a patient's need for dialysis (e.g., EPO) will not be
treated as outpatient prescription drugs subject to the Stark II prohibition on
self-referral, this informal position is not binding on HCFA, and there can be
no assurance that final Stark II regulations will adopt such a position. With
respect to the other items and services provided by the Company that are likely
to be deemed to be "designated health services" subject to the Stark II
prohibition, the language of Stark II and of the Stark I final regulation
suggest that the Company will not be permitted to offer such services in the
absence of a Stark II exception.
 
     Stark II contains exceptions for ownership or compensation arrangements
that meet certain specific criteria set forth in the statute or in forthcoming
regulations. With respect to ownership, certain qualifying in-office physician
or ancillary services provided by or under the supervision of physicians in a
single group practice are exempt from both ownership and compensation
arrangement restrictions. With respect to compensation arrangements, exceptions
are available for certain qualifying arrangements in the following areas: (a)
bona fide employment relationships; (b) personal services contracts; (c) space
and equipment leasing arrangements; (d) certain group practice arrangements with
a hospital that were in existence prior to December 1989; and (e) purchases by
physicians of laboratory services, or of other items and services at fair market
value. In order to be exempt from the Stark II self-referral prohibition, it is
necessary to meet all of the criteria of a particular exception for each
financial relationship existing between an entity and a referring physician. The
Company believes that several of its financial relationships with referring
physicians will meet the criteria for an exception. For example, the company
believes, based on the language of Stark II, that its agreements with Medical
Directors of their professional practices materially satisfy the exception for
compensation pursuant to a personal services contract. Similarly, the company
believes, based in part on the legislative history to Stark II, that it has a
reasonable basis for concluding that its contractual relationships with
hospitals for acute inpatient dialysis services should be deemed to satisfy the
criteria for the exceptions for personal services or leased equipment
arrangements. In the case of certain other financial arrangements, however,
there may be no exception available.
 
                                       36
<PAGE>   38
 
     Stark II also includes an exception for a physician's ownership or
investment interest in securities listed on an exchange or quoted on the NASDAQ
Stock Market which, in either case, meet certain criteria. Such criteria include
a requirement that the issuer of such securities have at least $75.0 million in
stockholder equity at the end of the issuer's most recent fiscal year or on
average during the previous three (3) fiscal years. Prior to the Offering, the
Company has not had stockholder equity of at least $75.0 million, but expects
that the net proceeds to the Company from the Offering will enable it to meet
that requirement as of the end of 1996.
 
     Because physicians under contract with the Company may refer patients to
hospitals with which the Company has an acute inpatient dialysis service
arrangement, Stark II may be interpreted by HHS to apply to the company's acute
dialysis arrangements with hospitals. However, Stark II contains exceptions for
certain equipment rental and personal services arrangements, and the company
believes it has a reasonable basis for concluding that its contractual
arrangements with hospitals for acute inpatient dialysis services are in
material compliance with the requirements of such exceptions to Stark II.
 
     Consequently, if it were to apply, Stark II may require the Company to
restructure certain existing compensation agreements with its Medical Directors
or, in the alternative, to refuse to accept referrals for designated health
services from such physicians. Moreover, since Stark II prohibits Medicare or
Medicaid reimbursement of items or services provided pursuant to a prohibited
referral, and imposes substantial civil monetary penalties on entities which
present or cause to be presented claims for reimbursement in such cases, the
Company could be required to repay amounts reimbursed for items and services
that HCFA determines to have been furnished in violation of Stark II, and could
be subject to substantial civil monetary penalties, either or both of which
could have a material adverse effect on the Company's operations, net revenue or
earnings. The Company believes that if Stark II is interpreted to apply to the
Company's operations, the Company will be able on a prospective basis to bring
its financial relationships with referring physicians into material compliance
with the provisions of Stark II, including relevant exceptions, although
prospective compliance would not affect amounts or penalties determined to be
owed for past conduct, and there can be no assurance that such prospective
compliance, if possible, will not have a material adverse effect on the
Company's operations, net revenue or earnings. If Stark II is interpreted by HHS
to apply to the Company and the Company is determined to be liable for past
violations of Stark II by itself or one or more of the entities it has acquired,
the application of Stark II could have a material adverse effect on the Company.
 
STATE REFERRAL REGULATIONS
 
     Several states have enacted statutes prohibiting physicians from holding
financial interests in various types of medical centers to which they refer
patients. The Company believes, based on its understanding of such state laws,
that its arrangements with physicians are in material compliance with such state
laws. However, given the recent enactment of such state laws, there is an
absence of definitive interpretative guidance in many areas and there can be no
assurance that one or more of the practices of the Company might not be subject
to challenge under such state laws. If one or more of such state laws is
interpreted to apply to the Company and the Company is determined to be liable
for violations of such state laws by itself or one or more of the entities it
has acquired, the application of such state laws could have a material adverse
effect on the Company.
 
FALSE CLAIMS
 
     The Company is also subject to federal and state laws prohibiting an
individual or entity from knowingly and willfully presenting claims for payment
(by Medicare, Medicaid, or other third party payers) that contain false or
fraudulent information. These laws provide for both criminal and civil
penalties. Furthermore, providers found to have submitted claims which they knew
or should have known were false, fraudulent, or for items or services that were
not provided as claimed, or for medically unnecessary services may be excluded
from Medicare and Medicaid participation, required to repay previously collected
amounts, and/or subject to substantial civil monetary penalties. Although
dialysis centers are generally reimbursed by Medicare based upon prospectively
determined composite rates, the submission of Medicare cost reports and requests
for payments by dialysis centers will be covered by these laws. The Company
believes that it has procedures to
 
                                       37
<PAGE>   39
 
ensure the accurate completion of cost reports and requests for payment.
However, there can be no assurance that cost reports or requests for payment
filed by the Company's dialysis centers will be materially accurate or will not
be subject to challenge under these laws. Furthermore, there can be no assurance
that cost reports or payment requests previously submitted by any of the
entities acquired by the Company will not be challenged under these laws. Any
such challenges, including any related sanctions which might be assessed, could
have a material adverse effect on the Company's operations, net revenue and
earnings.
 
STATE LAWS REGARDING PROVISION OF MEDICINE AND INSURANCE
 
     The laws of many states prohibit physicians from splitting fees with
non-physicians and prohibit non-physician entities from practicing medicine.
These laws vary from state to state and are enforced by the courts and by
regulatory authorities with broad discretion. Although the Company believes its
operations as currently conducted are in material compliance with existing
applicable laws, many aspects of the Company's business operations, including
the structure of the Company's relationship with physicians, have not been the
subject of state of federal regulatory interpretation. There can be no assurance
that review of the Company's business by courts or regulatory authorities will
not result in determinations that could materially adversely affect the
operations, revenues or net earnings of the Company or that the health care
regulatory environment will not change so as to restrict the Company's existing
operations or their expansion. In addition, expansion of the operations of the
Company to certain jurisdictions may require structural modifications of the
Company's form of relationships with physician groups, which could have a
material adverse effect on the operations, revenues and net earnings of the
Company.
 
     Most states have laws regulating insurance companies and HMOs. The Company
is not qualified in any state to engage in the insurance or HMO business. As the
managed care business evolves, state regulators may begin to scrutinize the
practices of, and relationships between, third-party payers, medical service
providers and entities providing management and other services to medical
service providers with respect to the application of insurance and HMO laws and
regulations. The Company believes, based on its general knowledge of the health
care, HMO and insurance industries as operated in the states in which its
centers are located, that its practices are consistent with those of other
health care companies and should not subject it to such laws and regulations.
However, given the limited regulatory history with respect to such practices,
there can be no assurance that states will not attempt to regulate the Company
as an insurer or HMO. If the Company is subject to prosecution or other
enforcement proceeding by state regulatory agencies, it may be required to
change or discontinue certain practices which could have a material adverse
effect on the operations, revenues and net earnings of the Company.
 
HEALTH CARE LEGISLATION
 
     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 reducing the amounts otherwise
payable by the program to health care providers in order to achieve deficit
reduction targets, among other reasons. Legislation or regulations may be
enacted in the future that may significantly modify the Medicare ESRD program or
substantially reduce the amount paid for the Company's services. For example,
the 1995 budget reconciliation bill sent by Congress to the President (and
subsequently vetoed by the President) proposed extending the period during which
Medicare payment for ESRD would be secondary to a patient's employer group
health plan from 18 to 30 months. In addition, the conference report to the
reconciliation bill called for HHS to report to Congress not later than December
31, 1999 with recommendations on expanding the definition of individuals
eligible to enroll in the bill's proposed MedicarePlus managed care plans to
include ESRD patients, and the President's response would have immediately made
such persons eligible for participation in such plans.
 
     The Health Insurance Portability and Accountability Act of 1996, signed
into law in August 1996, will, among other things, provide for insurance
portability for individuals who lose or change jobs, limit exclusions for
preexisting conditions, and establish a pilot program for medical savings
accounts. In addition, this legislation also greatly expands federal efforts at
combating health care fraud and abuse by making numerous amendments to the
Social Security Act and the federal criminal code. Among other things, the new
 
                                       38
<PAGE>   40
 
legislation creates a new "Health Care Fraud and Abuse Control Account,"
provides for the issuance of "advisory opinions" by the OIG regarding the
application of the anti-kickback statute, extends certain criminal penalties for
Medicare and Medicaid fraud to other federal health care programs, expands the
exclusion authority of the OIG, extends Medicare and Medicaid civil monetary
penalty provisions to other federal health care programs, increases the amounts
of civil monetary penalties, and establishes a criminal health care fraud
statute. Most of the Act's fraud and abuse provisions take effect on January 1,
1997.
 
     Furthermore, statutes or regulations may be enacted which impose additional
requirements on the Company to maintain eligibility to participate in the
federal and state payment programs. Such new legislation or regulations may have
a material adverse effect on the Company's operations, revenue or earnings.
 
OTHER REGULATIONS
 
     The Company's operations are subject to various state hazardous waste
disposal laws. Those laws as currently in effect do not classify most of the
waste produced during the provision of dialysis services to be hazardous,
although disposal of non-hazardous medical waste is also subject to regulation.
OSHA regulations require employers of workers who are occupationally subject to
blood or other potentially infectious materials require employers of workers who
are occupationally subject to blood or other potentially infectious materials to
provide those workers with certain prescribed protections against blood borne
pathogens. These regulatory requirements apply to all health care centers,
including dialysis centers, 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 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 certain record-keeping
requirements. Some states have established certificate of need ("CON") programs
regulating the establishment or expansion of health care centers, including
dialysis centers. The Company believes that it is in material compliance with
the foregoing laws and regulations.
 
     The Company believes it is in material compliance with all applicable laws
and regulations. No assurance can be made that in the future the Company's
business arrangements, past or present, will not be the subject of an
investigation or prosecution by a federal or state governmental authority. Such
investigation could result in the imposition of any combination of the penalties
discussed above depending upon the agency involved in such investigation and
prosecution. None of the Company's business arrangements with physicians,
vendors, patients or others have been the subject of investigation by any
governmental authority. No assurance can be given that the Company's activities
will not be reviewed or challenged by regulatory authorities. The Company
monitors legislative developments and would seek to restructure a business
arrangement if the Company determined that one or more of its business
relationships placed it in material noncompliance with such a statute. The
Company believes that in the near future the health care service industry will
continue to be subject to substantial regulation at the federal and state
levels, the scope of which cannot be predicted by the Company. Any loss by the
Company of its various federal certifications, its authorization to participate
in the Medicare and Medicaid programs or its licenses under the laws of any
state or other governmental authority from which a substantial portion of its
revenues are derived would have a material adverse effect on its operations,
revenues and net earnings.
 
COMPETITION
 
     The dialysis industry is fragmented and highly competitive. Competition for
qualified physicians to act as Medical Directors is also significant. According
to HCFA, there were in excess of 2,800 dialysis centers in the United States at
the end of 1995. The Company believes that approximately 38% were owned by
multi-center dialysis companies, 32% were owned by independent physicians and
30% were hospital-based centers. Certain of the Company's competitors have
substantially greater financial resources than the Company and may compete with
the Company for acquisitions, development and/or management of dialysis centers
and nephrology practices. The Company believes that competition for acquisitions
has increased the cost of acquiring dialysis centers and will likely increase
the cost of acquiring nephrology practices. The Company may also experience
competition from centers established by former Medical Directors or other
referring
 
                                       39
<PAGE>   41
 
physicians. There can be no assurance that the Company will be able to compete
effectively with any such competitors.
 
PROPERTIES
 
     Excluding the eight managed centers, the Company operates 77 dialysis
centers in 12 states, of which 58 are located in leased facilities and 19 are
owned. Certain of the premises are leased from physicians who practice at the
center and who are stockholders of the Company. The Company's leases generally
have terms ranging from one to 15 years and typically contain renewal options.
The sizes of the Company's centers range from approximately 400 to 17,000 square
feet. The Company leases office space in Nashville, Tennessee for its corporate
headquarters and university division under leases that expire in 2002 and 1999.
The Company considers its physical properties to be in good operating condition
and suitable for the purposes for which they are being used.
 
     Expansion or relocation of the Company's dialysis centers would be subject
to compliance with conditions relating to participation in the Medicare ESRD
program. In states that require a certificate of need, approval of an
application submitted by the Company would be necessary for expansion or
development of a new dialysis center. The Company generally owns the equipment
used in its outpatient centers. The Company considers its equipment to generally
be in good operating condition and suitable for the purposes for which it is
being used.
 
LEGAL PROCEEDINGS
 
     The Company is subject to claims and suits in the ordinary course of
business, including those arising from patient treatment, which the Company
believes will be covered by malpractice insurance. The Company is not currently
a party to any material legal actions.

Compensation Committee, composed solely of non-employee directors, is
responsible for establishing salaries, bonuses, and other compensation for the
Company's executive officers and administering any stock option and other
employee benefit plans of the Company. The Company's Nominating Committee is
responsible for considering nominations of Directors to the Company's Board of
Directors. The Company's Audit Committee, composed solely of nonemployee
directors, recommends the annual appointment of the Company's auditors, and, in

the Company's Board of Directors. Each non-employee member of the Board of
Directors receives a fee of $2,000 for each meeting of the Board of Directors

Company, including members who are employees, receive reimbursement of
out-of-pocket expenses incurred in connection with attending Board of Directors
or committee meetings thereof. In February 1996, Dr. Jacobson was paid $75,000

(1) The potential realizable value through the expiration date of the options
     has been determined on the basis of the market price per share at the time
     of grant compounded annually over the term of the option, net of the
     exercise price. These values have been determined based upon assumed rates
     of appreciation mandated by the Securities and Exchange Commission and are
     not intended to forecast the possible future appreciation, if any, of the
     price or value of the Common Stock.
(2) The number of options granted to all employees in 1995 includes options to
     purchase 673,948 shares of Common Stock, but does not include options to
     purchase 115,500 shares of the Common Stock of Tennessee granted in April
     1994 and January 1995 that were assumed by the Company in the Combination
     in February 1996 on a share-for-share basis.
(3) Does not include warrants to purchase 90,000 shares of the common stock of
     Tennessee granted in February 1994 at a price of $10.00 per share that were
     assumed by the Company in February 1996 on a share-for-share basis but with
     an exercise price of $7.50 per share. These warrants were exercisable as of
     the grant date.
(4) In the event of certain changes in control of the Company and the
     termination of the employment of the optionee, or in the event of certain
     changes in control of the Company that result in the Common Stock or stock
     of a successor not being traded on a national securities market, these
     options may accelerate and be "cashed out" under the circumstances
     described under "Management -- Stock Option and Stock Purchase
     Plans -- 1996 Stock Option Plan."
(5) Does not include the following options to purchase shares of the common
     stock of Tennessee granted in April 1994 that were assumed by the Company
     in February 1996 on a share-for-share basis: 30,000 shares at an exercise
     price of $7.50 per share; 25,000 shares at an exercise price of $6.00 per
     share; 20,000 shares at an exercise price of $3.50 per share; and 10,000
     shares at an exercise price of $2.00 per share.
(6) Options are exercisable as to 20% of these shares as of the grant date, and
     an additional 20% will vest on each of the first four anniversaries of the
     grant date.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     The members of the Company's Compensation Committee are Joseph C. Hutts,
Stephen D. McMurray, M.D., and W. Tom Meredith, M.D. Mr. Brooks, the Chief
Executive Officer, President and a Director of the Company, is a member of the
board of directors of PhyCor, Inc., of which Mr. Hutts is the Chairman of the
Board, President and Chief Executive Officer. See "Certain Transactions."
 
EMPLOYMENT AGREEMENTS
 
     The Company has entered into or assumed employment and non-competition
agreements with certain of its principal executive officers, including Messrs.
Brooks, Hinds, Brukardt and Cashia and Dr. Hakim, and with certain other key
personnel, except that Dr. Hakim's agreement does not contain non-competition
provisions. The Company has not and does not expect to enter into an employment
agreement with
 
                                       44
<PAGE>   46
 
Dr. Jacobson, the Chairman of the Board, because he does not devote his full
time and attention to the affairs of the Company. Other than Dr. Hakim, each
Named Executive Officer's employment agreement contains restrictive covenants
prohibiting such officer from competing with the Company for a period of one
year after the end of the employment term. The terms of the employment
agreements commenced on February 12, 1996 and will continue for a term of three
years and successive one year renewal terms thereafter, except for Mr. Cashia's
which was assumed by the Company on February 12, 1996 and expires March 31,
1997, and Mr. Brukardt's which commenced on July 22, 1996 and will continue for
a term of three years and successive one year renewal terms thereafter.
 
     The annual salaries of the Named Executive Officers as set forth in the
employment agreements are $250,000, $220,000, $200,000, $184,000 and $200,000
for Messrs. Brooks, Brukardt, Hinds and Cashia, and Dr. Hakim, respectively.
Each Named Executive Officer is eligible under his employment agreement for
bonuses at the sole discretion of the Company (up to a maximum, in Mr. Cashia's
agreement, of $50,000).
 
     The employment agreements of Messrs. Brooks, Brukardt and Hinds, also
provide for severance for each such Named Executive Officer of (i) his salary
for 12 months if such officer is terminated without cause, (ii) his salary for
one month if such officer is terminated for cause, or (iii) his salary for 36
months if such officer is terminated within 12 months of certain changes in
control of the Company either (A) without cause, or (B) by resignation of the
officer as a result of declining to accept reassignment to a job that is not the
equivalent of his then current position. Dr. Hakim's employment agreement
contains similar severance provisions that become operative if he enters into a
non-competition agreement.
 
     In addition to the above provisions, Mr. Brooks' employment agreement also
provides for (i) life insurance coverage of $2.0 million, (ii) long term
disability insurance of 60% of Mr. Brooks' annual base salary, (iii) an annual
bonus of 75% of his annual base salary to be earned if the Company meets or
exceeds its earning per share projections as approved by the Compensation
Committee, (iv) a $100,000 payment for efforts related to the initial public
offering, paid out of the proceeds of the initial public offering, and (v)
severance as provided above but based upon his salary plus his prior year's
bonus instead of just his salary.
 
     The Company assumed the employment agreement between Tennessee and Mr.
Cashia dated April 4, 1994. Mr. Cashia's agreement provides for severance of his
salary for 12 months and the amount of any bonus paid to Mr. Cashia in the prior
year, and medical coverage during such 12 months for himself and his family if
he is terminated without cause (as defined in his agreement).
 
STOCK OPTION AND STOCK PURCHASE PLANS
 
  Amended and Restated 1996 Stock Option Plan
 
     In January 1996, the Company adopted the Renal Care Group, Inc. 1996 Stock
Option Plan (the "Employee Plan"), which was amended and restated effective
September 1996. Under the Employee Plan, options to purchase a total of
1,000,000 shares of Common Stock were reserved for grant to eligible employees
and consultants of the Company. Options granted under the Employee Plan may
qualify as incentive stock options under Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code"), or nonqualified stock options. Any key
employee or consultant of the Company selected by the Compensation Committee
will be eligible for grants under the Employee Plan. The Compensation Committee
will determine the number of shares of Common Stock subject to each grant and
prescribe the other terms and conditions of each grant. Options will become
exercisable and expire at such time and in such installments as the Compensation
Committee shall determine.
 
     The Board of Directors, in its discretion, may amend, terminate or modify
the Employee Plan from time to time without stockholder approval; provided,
however, that the Committee may condition any amendment on the approval of
stockholders if such approval is necessary or deemed advisable with respect to
tax, securities or other applicable laws, policies or regulations. No
termination, amendment or modification of the Employee Plan shall adversely
affect any option previously granted under the plan, without the written consent
of the option holder.
 
                                       45
<PAGE>   47
 
     In the event of a change of control of the Company (as defined in the
Employee Plan), the Employee Plan requires that upon the termination of
employment of any employee option holder within 12 months after such change in
control (except for terminations for death, certain disabilities, cause, or
certain resignations), any vesting of such employee's outstanding options under
the Employee Plan will accelerate and the Company or its successor must "cash
out" such options by paying such employee an amount for each share subject to
such options equal to the difference of (i) the greater of the fair market value
of a share of Common Stock on the date of termination or the highest closing
price per share of Common Stock during the 90 day period ending on the date of
the change in control of the Company, minus (ii) the exercise price. In
addition, upon any such change in control of the Company that results in the
Common Stock or the stock of any successor to the Company ceasing to be publicly
traded in a national securities market, the foregoing acceleration and "cash
out" provisions (except that the "cash out" value is measured solely by the
difference of (i) the highest closing price per share of Common Stock during the
90 day period ending on the date of the change in control of the Company, minus
(ii) the exercise price) will be triggered for all outstanding option holders
under the Employee Plan unless otherwise determined by the Board of Directors.
 
  1996 Stock Option Plan For Outside Directors
 
     In January 1996, the Company adopted the Director Plan and reserved 100,000
shares of Common Stock for issuance to non-employee directors of the Company
thereunder. The Director Plan provides for grants of options to purchase 2,500
shares of Common Stock to "outside directors" who have been directors for at
least six months on the day after each annual meeting of stockholders of the
Company, and for grants of options to purchase 5,000 shares of Common Stock to
"outside directors" on the day such persons first become directors of the
Company. For purposes of the Director Plan, "outside director" means any
non-employee director who is not the Chairman or Vice Chairman of the Board and
who also is not a party to, and whose medical practice is not a party to, a then
currently effective Medical Director Agreement with the Company. The option
price for each option granted under the Director Plan will be equal to 100% of
the fair market value on the date of grant. An option under the Director Plan
will be immediately exercisable and will remain exercisable for ten years from
the date of grant. In the event of a change of control of the Company (as
defined in the Director Plan) that results in the Common Stock or the stock of
any successor to the Company ceasing to be publicly traded or quoted in a
national securities market, the Director Plan requires that the Company or its
successor must "cash out" such options by paying the director an amount for each
share subject to such options equal to the difference of the highest closing
price per share of Common Stock during the 90 day period ending on the date of
the change in control of the Company, minus the exercise price.
 
  Amended and Restated Employee Stock Purchase Plan
 
     The Renal Care Group, Inc. Amended and Restated Employee Stock Purchase
Plan (the "Purchase Plan") was adopted in January 1996 and became effective
February 6, 1996. A total of 300,000 shares of Common Stock have been reserved
for issuance under the Purchase Plan, which is intended to qualify under Section
423 of the Code. The Purchase Plan allows participants to purchase shares of
Common Stock in connection with option periods commencing January 1 and ending
the following December 31 (except the first option period which commenced
February 6, 1996 and ends December 31, 1996).
 
     The Purchase Plan permits eligible employees of the Company and certain of
its subsidiaries to purchase Common Stock through payroll deductions, which may
not exceed 10% of the employee's base compensation, at a price equal to 85% of
the fair market value of the Common Stock at the beginning of the option period
or at the end of the option period, which ever is lower (subject to a minimum
price specified in the Purchase Plan). Employees are eligible to participate in
the Purchase Plan if they are employed by the Company or a participating
subsidiary for at least 20 hours per week and more than five months in any
calendar year and have been employed for at least six months since their last
date of hire, except that credit is given for service with acquired companies.
 
     In the event of a change of control of the Company (as defined in the
Purchase Plan), each option under the Purchase Plan will (if the Company is the
surviving corporation) pertain to and apply to the securities to which a holder
of the number of shares of the Company subject to such option would have been
entitled in such transaction. If the Company is not the surviving corporation in
such change in control, then all options
 
                                       46
<PAGE>   48
 
under the Purchase Plan will terminate, provided that the Compensation Committee
may determine that such options shall be exercisable on the day prior to such
change in control transaction.
 
                              CERTAIN TRANSACTIONS
 
CONSIDERATION FOR FOUNDING COMPANIES
 
     In connection with the Combination, and as consideration for their

5% or more of the Common Stock received cash (excluding $7.0 million of
contingent payments), shares of Common Stock (valued at the initial public
offering price of $18.00 per share) and notes approximately as follows: Harry R.
Jacobson, M.D. (Chairman of the Board) -- $2,674,000; Sam A. Brooks, Jr.
(President, Chief Executive Officer and Director) -- $1,337,000 (received in the

Dr. Meredith -- $6,888,000; Dr. Lowery -- $5,281,000; and Kidney Care --

Founding Companies were obligated approximately as follows: Dr.
Bower -- $2,244,000; Dr. McMurray -- $6,618,000; and Dr. Lowery -- $2,300,000,
all of which indebtedness was repaid with a portion of the proceeds of the
Company's initial public offering.
 
TENNESSEE WARRANTS
 
     Various options and warrants of Tennessee outstanding at the time of the
Combination were assumed by the Company, on a share-for-share basis unadjusted
for the exchange rate in the transactions with Tennessee in the Combination. In
addition, the exercise price of the outstanding warrants of Tennessee was
reduced from $10.00 to $7.50 per share upon consummation of the Combination. Sam
A. Brooks, Jr., and Harry R. Jacobson, M.D., hold warrants for the purchase of
90,000 and 70,000 shares, respectively.
 
ISSUANCE OF CONVERTIBLE NOTES
 
     The Company issued $1.38 million of Convertible Notes on December 7, 1995

$100,000 (7.2% of the outstanding); Dr. McMurray -- $20,000 (1.4% of the
outstanding); Dr. Meredith -- $120,000 (8.7% of the outstanding); Dr.
Lowery -- $100,000 (7.2% of the outstanding); and Kidney Care -- $160,000 (11.6%
of the outstanding). The executive officers and directors as a group purchased
(and currently own) $340,000 of Convertible Notes (24.6% of the outstanding).
The Convertible Notes bear interest at 7.0% and, if not previously converted,
mature on December 7, 1996. The holders may convert the principal balance and
accrued interest into Common Stock at $7.50 per share and the Company may redeem
the Convertible Notes at par plus accrued interest. The shares of Common Stock
into which the Convertible Notes may be converted are eligible for the "piggy
back" registration rights applicable to the shares acquired by such holders in
the Combination.

     The Company believes that each of the foregoing Medical Director Agreements
were obtained on terms no less favorable to the Company than could be obtained
from unaffiliated third parties. The terms of each such Medical Director
Agreement were determined by arm's-length negotiations between the Company and
the practices, and such terms were subject to scrutiny and negotiations with
representatives of the Founding Companies in connection with the Combination.
 
LABORATORY MANAGEMENT AGREEMENT
 
     The Company entered into an agreement with Kidney Care dated February 12,
1996, pursuant to which the Company provides certain business, management,

laboratory located in Jackson, Mississippi. The agreement has a term of one year
with a provision for automatic renewal for an additional one year term. In
consideration for the management services provided by the Company, Kidney Care
has agreed to pay the Company a fixed management fee of $250,000 per year and to
reimburse the Company for its expenses in providing services under the
agreement, including the cost of certain employees, laboratory supplies and

Drs. Bower, Lowery and McMurray, respectively.
 
PURCHASE OF REAL PROPERTY
 
     The Company has purchased certain real property owned by Dr. Bower on which
certain of the centers previously operated by Kidney Care are located. The
purchase price was paid by the Company by the issuance of 68,000 shares of
Common Stock valued at the initial public offering price of $18.00 per share
plus the assumption of approximately $1.1 million of indebtedness incurred by
Dr. Bower to finance such property. The consideration paid to Dr. Bower for the
real estate was determined by arm's-length negotiations between the Company and
Dr. Bower, and such consideration was subject to scrutiny by and negotiations
with representatives of the Founding Companies.

LEASES OF REAL PROPERTY
 
     Pursuant to a lease agreement dated February 12, 1996, the Company leases
from an affiliate of Dr. Bower approximately 20,000 square feet of
administrative and other space used by the Company for the operation of the
centers acquired from KidneyCare. The lease is a triple net lease at a rate of
approximately $6.00 per square foot per year, or a gross payment of
approximately $10,000 per month. The lease contains an initial term of ten years
and two five-year renewal options.
 
     Dr. Lowery owns a 25% interest in certain real property and improvements

rent payable at $12.00 per square foot per year. The Tyler lease requires a
gross payment of $20,092 per month, and the Carthage lease requires a gross
payment of $2,479 per month. Each lease has an initial term of ten years with
two additional five-year renewal options. The amount of rent is subject to a
consumer price index adjustment after the initial five-year period. In addition,
the Company has subleased back to Tyler Nephrology Associates, Inc. a portion of
the Tyler center on terms substantially similar to those contained in the lease
of such center to the Company.
 
     Dr. Meredith owns a one-third interest in a partnership that subleases to
the Company approximately 4,100 square feet for its Dodge City, Kansas center.
The sublease, dated February 12, 1996, has a term of five years, with five
additional options to renew for periods of five years. The sublease is a double
net sublease with a base rent payment of approximately $3,300 per month,
adjusted at the commencement of each extended term by a factor based on the
consumer price index.
 
EMPLOYMENT AGREEMENT
 
     Ann N. Bower, Dr. Bower's daughter, is a party to an employment agreement
dated February 12, 1996 with the Company with an annual base salary of $125,000
and having a term of three years, renewable thereafter for successive one-year
terms. Ms. Bower serves as the chief operating officer of the Company's
Mississippi operations.
 
RELATIONSHIP WITH VANDERBILT UNIVERSITY
 
     Dr. Jacobson currently serves as Deputy Vice Chancellor of Health Affairs
at Vanderbilt University and as Professor of Medicine and Director of the
Division of Nephrology, Department of Medicine, Vanderbilt University. On
February 12, 1996, the Company assumed a Dialysis Center Management Agreement
with Vanderbilt University Medical Center pursuant to which the Company manages
its outpatient dialysis center. The Company received revenues of approximately
$132,500 pursuant to this agreement for the six months ended June 30, 1996. Such
agreement has a one-year term that is automatically renewed each year unless
either party cancels the agreement at least 90 days prior to the end of the
current term. Vanderbilt University owns approximately 247,616 of the
outstanding shares of the Company.
 
SUPPLY RELATIONSHIP
 
     The Company has entered into an agreement dated February 12, 1996, with
Healthcare Suppliers, Inc. ("HSI"), a former affiliate of Kidney Care, pursuant
to which the Company is obligated, for a period of 18 months, to purchase most
of the dialysis and related supplies required for its Kidney Care centers at
pre-determined prices no greater than the best prices available to any other
Founding Company as of November 1995. The Company believes it will purchase
approximately $5.0 million of supplies from HSI during the 18-month term of the
agreement.
 
COMPANY POLICY
 
     The Company has adopted a policy pursuant to which transactions with
affiliates (other than those entered into pursuant to the Combination) must be
reviewed by the Audit Committee and approved by a majority of the disinterested
members of the Board of Directors and will be made on terms no less favorable to
the Company than could be obtained from unaffiliated third parties.

                          DESCRIPTION OF CAPITAL STOCK
 
     The following summary is a description of certain provisions of the
Company's Amended and Restated 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 Company's Amended and Restated Certificate of
Incorporation.
 
     The Company's authorized capital stock consists of 22,000,000 shares, $.01
par value, of Common Stock and 10,000,000 shares of Preferred Stock, $.01 par
value ("Preferred Stock"). Upon completion of the Offering, the Company will
have outstanding 14,125,954 shares of Common Stock (14,575,954 if the
Underwriters' over-allotment option is exercised in full) and no shares of
Preferred Stock. As of October 7, 1996, there are approximately 1,800 record
holders of Common Stock.
 
COMMON STOCK
 
     The holders of Common Stock are entitled to one vote per share on all
matters to be voted on by stockholders and are not entitled to cumulative voting
in the election of directors. The holders of Common Stock are entitled to share
ratably in dividends, if any, as may be declared from time to time by the Board
of Directors in its discretion out of funds legally available therefor. The
Company currently anticipates that all of its earnings will be retained to
finance the growth and development of its business and, therefore, does not
anticipate that any cash dividends will be declared on the Common Stock in the
foreseeable future. The holders of Common Stock are entitled to share ratably in
any assets remaining after satisfaction of all prior claims upon liquidation of
the Company. The Company's Amended and Restated Certificate of Incorporation
gives holders of Common Stock no preemptive or other subscription or conversion
rights, and there are no redemption provisions with respect to such shares. All
outstanding shares of Common Stock are, and the shares offered hereby will be,
when issued and paid for, fully paid and nonassessable. The rights, preferences,
and privileges of holders of Common Stock are subject to, and may be adversely
affected by, the rights of holders of shares of any series of Preferred Stock
which the Company may designate and issue in the future. See "Dividend Policy."
 
PREFERRED STOCK
 
     Subject to conditions specified in the Company's Amended and Restated
Certificate of Incorporation, the Delaware General Corporation Law ("DGCL") and
other applicable law, the Board of Directors has the authority to issue
undesignated Preferred Stock in one or more class or series and to determine the
dividend rights, dividend rate, conversion rights, voting rights, redemption
rights and terms, liquidation preferences, sinking fund provisions, number of
shares constituting any class or series, and designations of such class or
series without any further vote or action by the stockholders of the Company.
The Company has no present intention to issue any shares of Preferred Stock.
 
     One of the effects of undesignated Preferred Stock is to enable the Board
of Directors to render more difficult or to discourage an attempt to obtain
control of the Company by means of a tender offer, proxy contest, merger or
otherwise, and thereby to protect the continuity of the Company's management.
For example, the Company could issue a series of preferred stock having
characteristics that would make a takeover prohibitively expensive. The issuance
of shares of the Preferred Stock pursuant to the Board of Directors' authority
described above may adversely affect the rights of the holders of Common Stock.
For example, Preferred Stock issued by the Company may rank senior to the Common
Stock as to dividend rights, liquidation preference or both, may have full or
unlimited voting rights and may be convertible into shares of Common Stock.
Accordingly, the issuance of shares of Preferred Stock may discourage bids for
the Common Stock or may otherwise adversely affect the market price of the
Common Stock.
 
SPECIAL PROVISIONS OF THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION,
BYLAWS AND DELAWARE LAW
 
     Certain provisions of the Company's Amended and Restated Certificate of
Incorporation and Bylaws may be deemed to have an anti-takeover effect or may
delay, defer or prevent a tender offer or takeover attempt that a stockholder
might consider in such stockholder's best interest, including those attempts
that might result in a premium over the market price for the shares held by a
stockholder.
 
                                       52
<PAGE>   54
 
     Delaware Anti-Takeover Law.  Section 203 of the DGCL ("Section 203")
applies to the Company and generally provides that a person who, together with
affiliates and associates owns, or within three years did own, 15% or more of
the outstanding voting stock of a corporation subject to the statute (an
"Interested Stockholder") but less than 85% of such stock may not engage in
certain business combinations with the corporation for a period of three years
after the date on which the person became an Interested Stockholder unless (i)
prior to such date, the corporation's board of directors approved either the
business combination or the transaction in which the stockholder became an
Interested Stockholder, (ii) the Interested Stockholder acquired 85% or more of
the outstanding voting stock of the corporation in the same transaction that
makes such person an Interested Stockholder (excluding shares owned by persons
who are both officers and directors of the corporation, and shares held by
certain employee stock ownership plans), or (iii) subsequent to such date, the
business combination is approved by the corporation's board of directors and
authorized at a stockholders' meeting by a vote of at least two-thirds of the
corporation's outstanding voting stock not owned by the Interested Stockholder.
Section 203 defines the term "business combination" to encompass a wide variety
of transactions with or caused by an Interested Stockholder, including mergers,
asset sales, and other transactions in which the Interested Stockholder receives
or could receive a benefit on other than a pro rata basis with other
stockholders.
 
     The Company's stockholders, by adopting an amendment to the Certificate of
Incorporation, may elect not to be governed by Section 203, which election would
be effective 12 months after such adoption. Neither the Amended and Restated
Certificate of Incorporation nor the Bylaws presently exclude the Company from
the restrictions imposed by Section 203, and the restrictions imposed by Section
203 apply to the Company. The provisions of Section 203 could delay or frustrate
a change in control of the Company, deny stockholders the receipt of a premium
on their Common Stock and have a depressing effect on the market price of the
Common Stock. The provisions also could discourage, impede or prevent a merger,
tender offer or proxy contest, even if such event would be favorable to the
interests of stockholders.
 
     Classified Board of Directors.  The Amended and Restated Certificate of
Incorporation of the Company provides for the Board of Directors to be divided
into three classes of directors serving staggered three-year terms. A director
may be removed from office prior to the expiration of his or her term only "for
cause," so any person acquiring control of the Company would need three annual
meetings to replace all of the members of the Board of Directors. The classified
board provision of the Company's Amended and Restated Certificate of
Incorporation could have the effect of making the removal of incumbent directors
more time-consuming and difficult, and, therefore discouraging a third party
from making a tender offer or otherwise attempting to obtain control of the
Company, even though such an attempt might be beneficial to the Company and its
stockholders. Thus, the classified board provision could increase the likelihood
that incumbent directors will retain their positions. The Company believes that
a classified Board of Directors will help to assure the continuity and stability
of the Board of Directors and of the business strategies and policies of the
Company as determined by the Board of Directors. See "Management -- Board of
Directors."
 
     Number of Directors; Removal; Filling Vacancies.  The Amended and Restated
Certificate of Incorporation and Bylaws of the Company provide that the number
of directors will be fixed from time to time with the consent of two-thirds of
the Board of Directors. Moreover, the Amended and Restated Certificate of
Incorporation provides that directors may only be removed with cause by the
affirmative vote of the holders of at least a majority of the outstanding shares
of capital stock of the Company then entitled to vote at an election of
directors. This provision prevents stockholders from removing any incumbent
director without cause and allows two-thirds of the incumbent directors to add
additional directors without approval of stockholders until the next annual
meeting of stockholders at which directors of that class are elected.
 
     Advance Notice of Nominations and Stockholder Proposals.  The Company's
Bylaws contain a provision requiring at least 60 but no more than 90 days'
advance notice by a stockholder of a proposal or director nomination that such
stockholder desires to present at any annual or special meeting of stockholders,
which would prevent a stockholder from making a proposal or a director
nomination at a stockholder meeting without the Company having advance notice of
the proposal or director nomination. This provision could make a change in
control more difficult by providing the directors of the Company with more time
to prepare an opposition to a proposed change in control.
 
                                       53
<PAGE>   55
 
     Vote Requirement for Calling Special Meeting.  The Company's Bylaws also
contain a provision requiring the vote of the holders of two-thirds of the
outstanding Common Stock in order to call a special meeting of stockholders.
This provision would prevent a stockholder with less than a two-thirds interest
from calling a special meeting to consider a merger unless such stockholder had
first garnered adequate support from a sufficient number of other stockholders.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
     Limitations of Director Liability.  Section 102(b)(7) of the DGCL ("Section
102(b)") authorizes corporations to limit or to eliminate the personal liability
of directors to corporations and their stockholders for monetary damages for
breach of directors' fiduciary duty of care. Although Section 102(b) does not
change directors' duty of care, it enables corporations to limit available
relief to equitable remedies such as injunction or rescission. The Company's
Amended and Restated Certificate of Incorporation limits the liability of
directors to the Company or its stockholders to the full extent permitted by
Section 102(b). Specifically, directors of the Company are not be personally
liable for monetary damages for breach of a director's fiduciary duty as a
director, except for liability: (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 that involve intentional misconduct or a knowing violation of law,
(iii) for unlawful payments of dividends or unlawful stock repurchases or
redemptions as provided in Section 174 of the DGCL, or (iv) for any transaction
from which the director derived an improper personal benefit.
 
     Indemnification.  To the maximum extent permitted by law, the Amended and
Restated Certificate of Incorporation of the Company provides for mandatory
indemnification of directors and officers of the Company against an expense,
liability and loss to which they may become subject, or which they may incur as
a result of being or having been a director or officer of the Company. In
addition, the Company must advance or reimburse directors and officers for
expenses incurred by them in connection with indemnifiable claims.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Common Stock is First Union
National Bank of North Carolina.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of substantial amounts of Common Stock into the public market after
the Offering, 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 the sale or availability for future sale of shares of
additional Common Stock will have on the market price of the Common Stock
prevailing from time to time.
 
     Upon completion of the Offering, the Company will have 14,125,954 shares of
Common Stock outstanding (assuming no exercise of options or warrants and no
conversion of any Convertible Notes after the date of this Prospectus). The
3,000,000 shares sold in the Offering (plus any additional shares sold upon
exercise of the Underwriters' over-allotment option) and the 4,485,000 shares of
Common Stock sold in the initial public offering are freely tradable, except
that any shares purchased by "affiliates" of the Company, as that term is
defined in Rule 144 under the Securities Act of 1933, as amended,
("Affiliates"), may generally only be sold in compliance with the limitations of
Rule 144 ("Rule 144") under the Securities Act of 1933, as amended (the
"Securities Act"), as described below.
 
     The remaining 6,640,954 shares of Common Stock outstanding are not
registered under the Securities Act, and, accordingly, such shares may not be
sold except in transactions registered under the Securities Act or pursuant to
an exemption from registration. In addition, holders of approximately
shares of Common Stock have agreed not to sell any shares of Common Stock or
other capital stock or any securities convertible into, or exercisable or
exchangeable for, any shares of Common Stock or other capital stock for a period
of 180 days following the Offering, without the prior written consent of
Equitable Securities Corporation. After the expiration of such 180 day period,
all of such shares may be sold in accordance with
 
                                       54
<PAGE>   56
 
Rule 144, subject to the applicable volume, holding period and other limitations
of Rule 144 as described below. These same individuals have entered into a
similar agreement with the Company covering a period until February 7, 1997.
 
     The Company has granted certain registration rights to holders of 8,140,954
shares of restricted stock, of which 1,500,000 shares are being offered hereby.
If any such stockholder who has elected to participate in the Offering is not
able to dispose of 20% of his Common Stock in the Offering (40% in the case of
former stockholders of RenalWest), then such stockholders, upon the request of
persons holding at least 20% of the restricted shares of Common Stock, may
request, at any time prior to the expiration of the two-year holding period
specified in Rule 144 with respect to such shares, that the Company file a
registration statement under the Securities Act for an offering of no less than
10% of the restricted shares of Common Stock held by them. The Company is
obligated to effect only one such registration pursuant to such a request,
subject to certain exceptions. In addition, in the event that the Company
proposes to register under the Securities Act any Common Stock for its own
account or for the account of others at prior to the expiration of the two-year
holding period specified in Rule 144 with respect to such shares, subject to
certain exceptions, such stockholders have the right to require the Company to
include their shares in such registration, subject to the right of any managing
underwriter of the Offering to exclude some or all of the shares for marketing
reasons. In general, all fees, costs and expenses of such registrations (other
than underwriting commissions, dealer's fees, brokers' fees and concessions
applicable to shares of Common Stock registered and any counsel for the selling
stockholders) will be borne by the Company.
 
     In addition to the shares of Common Stock that will be outstanding, an
aggregate of up to 1,831,993 shares of Common Stock may be issued upon exercise
of options that the Company has outstanding. These options and warrants will be
exercisable as follows: (i) options and warrants to purchase up to        shares
of Common Stock are exercisable immediately; (ii) options to purchase up to
       shares of Common Stock will become exercisable on or prior to December
31, 1996; (iii) options to purchase up to        shares of Common Stock will
become exercisable on or prior to December 31, 1997; (iv) options to purchase up
to        shares of Common Stock will become exercisable on or prior to December
31, 1998; (v) options to purchase up to        shares of Common Stock will
become exercisable on or prior to December 31, 1999; and (vi) options to
purchase up to        shares of Common Stock will become exercisable on or prior
to December 31, 2000. The Company has filed a registration statement on Form S-8
under the Securities Act to register all shares of Common Stock subject to these
stock options. The shares covered by these registration statements will be
eligible for sale in the public markets, subject to the lock-up agreements
discussed above, if applicable.
 
     The Company has outstanding warrants to purchase an additional 220,000
shares of Common Stock. The outstanding warrants to purchase shares of Common
Stock grant certain registration rights to their holders that may be acquired
upon exercise of such warrants, which rights under appropriate circumstances
would allow holders of warrants to cause the Company to register such shares,
even if the Company does not elect to effect the registration that it intends to
effect as described above. Upon any such registration, the shares of Common
Stock registered will immediately be eligible for resale in the public market,
unless such shares are purchased by an Affiliate.
 
     Up to 184,000 additional shares may be issued upon conversion of the
Convertible Notes. These shares will not be registered under the Securities Act,
and, accordingly, such shares may not be sold except in transactions registered
under the Securities Act or pursuant to an exemption from registration. In the
event that the Company proposes to register under the Securities Act any Common
Stock for its own account or for the account of others during the first two
years following the completion of the Offering, subject to certain exceptions,
the holders of the Convertible Notes have the right to require the Company to
include their shares in such registration, subject to the right of any managing
underwriter of the offering to exclude some or all of the shares for marketing
reasons.
 
     Any shares of Common Stock that have not been registered under the
Securities Act could be sold under Rule 144. In general, under Rule 144 as
currently in effect, a person (or persons whose shares are aggregated) who has
beneficially owned restricted shares for at least two years, including a person
who may be deemed an
 
                                       55
<PAGE>   57
 
Affiliate, is entitled to sell within any three-month period a number of shares
of Common Stock that does not exceed the greater of 1% of the then-outstanding
shares of Common Stock or the average weekly reported trading volume of the
Common Stock during the four calendar weeks preceding such sale. Sales under
Rule 144 are subject to certain restrictions relating to manner of sale, notice,
and the availability of current public information about the Company. A person
who is not an Affiliate at any time during the three months preceding a sale,
and who has beneficially owned shares for at least three years, would be
entitled to sell such shares immediately following the Offering without regard
to the volume limitations, manner of sale provisions, or notice or other
requirements of Rule 144.
 
     The Securities and Exchange Commission has published a notice of proposed
rulemaking that, if adopted as proposed, would shorten the applicable holding
periods under Rule 144(d) and Rule 144(k) to one and two years, respectively
(from the current two- and three-year periods). The Company cannot predict
whether such amendments will be adopted or the effect thereof on the trading
market for its Common Stock.

     The Representatives have advised the Company that the Underwriters propose
initially to offer the Common Stock to the public on the terms set forth on the
cover page of this Prospectus. The Underwriters may allow selected dealers a
concession of not more than $     per share, and the Underwriters may allow, and
such dealers may reallow, a concession of not more than $     per share to
certain other dealers. After the Offering, the price and concessions and
reallowances to dealers may be changed by the Underwriters. The Common Stock is
offered subject to receipt and acceptance by the Underwriters and to certain
other conditions, including the right to reject orders in whole or in part.
 
     The Company has granted a 30-day option to the Underwriters, to purchase up
to a maximum of 450,000 additional shares of Common Stock to cover
over-allotments, if any, at the same price per share as the initial 3,000,000
shares to be purchased by the Underwriters. To the extent the Underwriters
exercise this option, each of the Underwriters will be committed, subject to
certain conditions, to purchase such additional shares in approximately the same
proportion as set forth in the above table. The Underwriters may purchase such
shares only to cover over-allotments made in connection with the sale of the
shares of the Common Stock offered hereby.
 
     The Underwriting Agreement provides that the Company will indemnify the
Underwriters against certain liabilities, including civil liabilities under the
Securities Act, or will contribute to payments the Underwriters may be required
to make in respect thereof.
 
     The Company, its directors, executive officers, affiliates and other
persons who are holders of        outstanding shares of Common Stock as of the
consummation of the Offering have agreed not to offer, issue, sell, contract to
sell, grant any option for the sale of, or otherwise dispose of, directly or
indirectly, any shares of Common Stock or any securities convertible into or
exchangeable for shares of Common Stock or any rights to acquire Common Stock
for a period of 180 days after the date of this Prospectus, without the prior
written consent of Equitable Securities Corporation. These same individuals have
entered into a similar agreement with the Company covering a period until
February 7, 1997. See "Shares Eligible for Future Sale."
 
     The Representatives have advised the Company that the Underwriters do not
intend to confirm any sales to accounts over which they exercise discretionary
authority.
 
     In connection with the Offering, certain Underwriters and selling group
members (if any) or their respective affiliates who are qualified registered
market makers on the Nasdaq Stock Market may engage in passive market making on
the Nasdaq Stock Market in accordance with rule 10b-6A under the Securities and
Exchange Act of 1934, as amended, during the two business day period before the
commencement of the offers or sales of the Common Stock. The passive market
making transactions must comply with the applicable volume and price limits and
be identified as such. In general, a passive market maker may display its bid at
a price not in excess of the highest independent bid for such security; if all
independent bids are lowered before the passive market maker's bid, however,
such bid must then be lowered when certain purchase limits are exceeded.

     On December 7, 1995, Equitable Securities Corporation ("Equitable")
purchased in a private placement an aggregate principal amount of $50,000 of
Convertible Notes from the Company. The Convertible Notes mature on December 7,
1996, bear interest at a rate of 7.0% per annum, and the principal and accrued
interest thereof are convertible at a conversion price of $7.50 per share. The
Convertible Notes, and the Common Stock into which the Convertible Notes are
convertible, will not be sold, transferred, assigned, pledged or hypothecated by
Equitable prior to February 6, 1997. The Convertible Notes provide that
Equitable has the same "piggyback" registration rights applicable to the former
owners of the Founding Companies in connection with the Common Stock received by
such persons in the Combination. As a result of the purchase of such Convertible
Notes, Equitable will be deemed to have received additional compensation in
connection with the Offering. Equitable also acted as financial advisor to Renal
Care Group and rendered a fairness opinion in connection with the acquisition of
RenalWest in September 1996 and received a fee for such services.
 
                                 LEGAL MATTERS

                  PRO FORMA COMBINING FINANCIAL STATEMENTS OF
                      RENAL CARE GROUP, INC. (OF DELAWARE)
 
     The following unaudited pro forma combining financial statements give
effect to the acquisition by Renal Care Group, Inc., a Delaware Corporation
("RCG" or the "Company"), of Kidney Care, Inc. et al. ("KCI") and Renal Care
Group, Inc. (of Tennessee) and Three Unrelated Businesses to be Acquired
("Tennessee") which occurred on February 6, 1996 contemporaneously with an
initial public offering of RCG's stock (the "Combination"). The Combination was
accounted for using historical cost basis, in accordance with Securities and
Exchange Commission Staff Accounting Bulletin No. 48. The historical financial
statements of RCG also include the results of operations of Main Line Suburban
Dialysis Centers, Inc. and RenalWest L.C., et al both accounted for as poolings
of interest. The unaudited pro forma combining financial statements have been
prepared by the Company based on the historical financial statements of RCG,
KCI, and Tennessee included elsewhere in this Prospectus, and certain
preliminary estimates and assumptions deemed appropriate by management of the
Company. These pro forma combining financial statements may not be indicative of
actual results as if the transactions had occurred on the dates indicated or
which may be realized in the future. The pro forma combining statements of
operations for the six months ended June 30, 1996 and year ended December 31,
1995, assume the Company had completed the Combination on January 1, 1996 and
1995, respectively. The pro forma combining statement of operations for the year
ended December 31, 1995 includes the results of operations of KidneyCare for the
twelve months ended on January 31, 1996.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors
Renal Care Group, Inc.
 
     We have audited the accompanying supplemental consolidated balance sheets
of Renal Care Group, Inc. (formed as a result of the merger of Renal Care Group,
Inc. and RenalWest L.C., et al.) as of December 31, 1994 and 1995, and the
related supplemental consolidated income statements, statements of changes in
owners' equity, and cash flows for each of the two years in the period ended
December 31, 1995. The supplemental consolidated financial statements and
schedule give retroactive effect to the merger of Renal Care Group, Inc. and
RenalWest L.C., et al. consummated on September 30, 1996, which has been
accounted for using the pooling-of-interests method as described in the notes to
the supplemental consolidated financial statements. These supplemental financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these supplemental financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the supplemental financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Renal Care Group, Inc. at December 31, 1994 and 1995 and the consolidated
results of operations and cash flows for each of the two years ended December
31, 1995 after giving retroactive effect to the merger of RenalWest L.C., et
al., as described in the notes to the supplemental consolidated financial
statements, in conformity with generally accepted accounting principles.

            NOTES TO SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENTS
                   (IN THOUSANDS, EXCEPT FOR PER SHARE DATA)
                               DECEMBER 31, 1995
 
1. ORGANIZATION AND BASIS OF PRESENTATION
 
     Renal Care Group, Inc. (of Delaware) (the "Company") was formed in June
1995, primarily for the purpose of acquiring four dialysis businesses and Renal
Care Group, Inc. (of Tennessee) ("Tennessee"), in exchange for shares of its
Common Stock, cash, notes payable and the assumption of certain debt (the
"Combination"). As discussed more fully in Note 12, on February 6, 1996, the
Company closed an initial public offering of 3,900 shares of its Common Stock
and simultaneously consummated the Combination. The four related businesses
acquired in the Combination, which are comprised of numerous legal entities,
conduct business as Kidney Care, Inc. and certain operating divisions of Medical
Enterprises, Ltd. and Health Care Suppliers, Inc. ("KCI"), DMN Professional
Corporation ("DMN"), Tyler Nephrology Associates, P.A. ("Tyler"), and Kansas
Nephrology Associates, P.A. ("KNA") and Kansas Dialysis Supply, Inc. ("KDS,"
combined, "Kansas"). Tennessee and the four unrelated businesses acquired are
based in Tennessee, Mississippi, Indiana, Texas, and Kansas.
 
     The Combination is being accounted for utilizing the historical cost basis
in accordance with Securities and Exchange Commission Staff Accounting Bulletin
No. 48 with the stock being valued at the historical cost of the net assets
exchanged. Cash consideration given in the Combination is treated for accounting
purposes as a dividend from the Company to Tennessee, KCI, DMN, Tyler, Kansas,
and their owners.
 
     In April 1996, the Company acquired Main Line Suburban Dialysis Centers,
Inc. ("Main Line") in a merger accounted for as a pooling-of-interests through
the exchange of 528 shares of the Company's Common Stock. In September 1996, the
Company acquired RenalWest, L.C., et al ("RenalWest") in a merger accounted for
as a pooling-of-interests through the exchange of 2,400 shares of the Company's
common stock. Generally accepted accounting principles proscribe giving effect
to a consummated business combination accounted for by the pooling-of-interests
method in financial statements that do not include the date of consummation.
These financial statements do not extend through the date of consummation of the
RenalWest merger; however, they will become the historical consolidated
financial statements of the Company after the financial statements including the
date of consummation of the RenalWest merger are issued. These financial
statements reflect the restated consolidated financial statements of the Company
effecting this pooling-of-interest.
 
     As mentioned above, on February 6, 1996, the Company completed an initial
public offering of 3,900 shares of Common Stock and on February 20, 1996, the
underwriters of the offering fully exercised their over allotment option for an
additional 585 shares. The 4,485 shares were issued at the initial public
offering price of $18 per share.
 
     Physician services are provided to the Company by stockholders or legal
entities owned by stockholders of the Company. Substantially all of the dialysis
treatments performed by the Company are referred by these related physician
groups.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company.
Significant intercompany transactions and accounts have been eliminated in
consolidation.
 
CASH EQUIVALENTS
 
     The Company considers all highly-liquid investments with original
maturities of three months or less to be cash equivalents.

     NOTES TO SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
INVENTORIES
 
     Inventories consist of drugs, supplies and parts consumed in dialysis
treatments and is stated at the lower of cost (using the average method and the
first-in, first-out method) or market.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost. Depreciation is provided by the
straight-line method over the useful lives of the related assets, generally
three to five years. Leasehold improvements are amortized using the
straight-line method over the related lease terms. Maintenance and repair costs
are charged to operations as incurred.
 
OTHER ASSETS
 
     Other assets at December 31, 1994 and 1995 consist primarily of costs
related to the Company's initial public offering. These costs were capitalized
and recorded as a reduction in proceeds from the initial public offering in
February 1996.
 
USE OF ESTIMATES
 
     The preparation of the Company's combined financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect amounts reported in the combined
financial statements and accompanying notes. Actual results could differ from
those estimates. During 1995, the Company changed its assumptions in estimating
the accounts receivable allowance for doubtful accounts, resulting in a $1,680
increase in the provision for doubtful accounts.
 
NET REVENUE
 
     Accounts receivable and net revenue are recorded at the estimated net
realizable amount from Medicare, Medicaid, patients, commercial insurers and
other third-party payors for services rendered. The Medicare and Medicaid
programs reimburse the Company at amounts that are different from the Company's
established rates. Contractual adjustments under these programs represent the
difference between the amounts billed for these services and the amounts that
are reimbursable by third party payors. A summary of the basis for reimbursement
with these payors follows:
 
  Medicare
 
     The Company is paid by the Medicare program on a prospective payment system
for dialysis services. Each facility receives a composite rate that is adjusted
to account for geographic differences in the cost of labor. The prospectively
determined composite rates are subject to retroactive adjustments.
 
  Medicaid
 
     Medicaid is a state administered program with reimbursements varying by
state. The Medicaid programs administered in each state in which the Company
operates reimburse the Company for dialysis services rendered.
 
  Other
 
     Other payments from patients, commercial insurers and other third-party
payors are received pursuant to a variety of reimbursement arrangements, which
are generally higher than those payments received from the Medicare and Medicaid
programs.
 
     The allowance for doubtful accounts represent management's estimate of
potential credit losses associated with amounts due from patients, commercial
insurers and other third-party payors. Management of

                             RENAL CARE GROUP, INC.
 
     NOTES TO SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
the Company does not believe that receivables from the Medicare and Medicaid
programs represent any credit risk.
 
     Reimbursements from Medicare and Medicaid at established rates approximated
83%, 78% and 71% for the years ended December 31, 1993 (unaudited -- Note 12),
1994 and 1995, respectively.
 
INCOME TAXES
 
     Prior to the Combination and mergers, KCI, DMN, Tyler, Kansas, Main Line
and RenalWest operated as not-for-profits, S Corporations or partnerships;
accordingly, income tax liabilities were the responsibility of the respective
owners or partners. Under these provisions, the entities did not pay corporate
income taxes; rather the income or loss was allocated to each stockholder for
inclusion in their respective income tax returns. Because of this practice,
provisions for income taxes and deferred tax assets and liabilities of these
taxable entities have not been reflected in these supplemental consolidated
financial statements.
 
     Tennessee and the Company are C Corporations and account for income taxes
under the liability method. Under this method, deferred tax assets and
liabilities are determined based upon differences between financial reporting
and tax basis assets and liabilities and are measured using the enacted tax laws
that will be in effect when the differences are expected to reverse.
 
ESTIMATED MEDICAL PROFESSIONAL LIABILITY CLAIMS
 
     The Company is insured for medical professional liability claims through
retrospectively rated commercial insurance policies. It is its policy that
provision for estimated premium adjustments to medical professional liability
costs be made for asserted and unasserted claims based on its experiences.
Provision for such professional liability claims included estimates of the
ultimate costs of such claims. To date, the Company's experience with such
claims has not been significant; accordingly, no such provision has been made.
 
OWNERS' EQUITY
 
     Owners' equity includes capital stock, additional paid-in capital and
retained earnings of the Company.
 
EARNINGS PER SHARE (UNAUDITED)
 
     Earnings per share for the six months ended June 30, 1996 is based on the
weighted average number of shares outstanding during the period including the
dilutive effect of options and warrants and the 2,928 shares issued in
connection with the Main Line and RenalWest mergers.
 
NEWLY ISSUED ACCOUNTING STANDARDS
 
     The Company has considered the impact of newly issued accounting
pronouncements, principally Statement of Financial Accounting Standards No 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of," and does not believe that adoptions of this and any other newly
issued pronouncements would have a significant impact on the consolidated
financial statements.
 
MARKET VALUE OF FINANCIAL INSTRUMENTS
 
     The Company's financial instruments include cash and cash equivalents,
long-term debt and capital lease obligations. The market values for these
financial instruments approximates their carrying value at December 31, 1994 and
1995.

3. MERGERS
 
     On April 26, 1996, the Company completed a merger with Main Line through
the exchange of shares of the Company's Common Stock with an aggregate value of
approximately $18,200 at the date of the merger agreement.
 
     On August 7, 1996, the Company entered into a definitive agreement to merge
with RenalWest, L.C. et al. This transaction was completed on September 30,
1996. Each share of RenalWest common stock then issued and oustanding was
canceled and retired then converted into one share of RenalWest common stock.
Renal Care Group, Inc. exchanged 2,400 shares of its common stock for the one
share of RenalWest common stock.
 
     The Main Line and RenalWest mergers have been accounted for as a
pooling-of-interests, and accordingly, the supplemental consolidated financial
statements give retroactive effect to the combined operations of Renal Care
Group, Inc. for all periods presented. The following is a summary of the results
of operations of the separate entities for periods prior to the Main Line and
RenalWest mergers:

their S Corporation status. The Company had operating income for income tax
purposes of $131, $4,641, and $2,990 for the years ending December 31, 1993,

Standard No. 109 would have been $50, $1,764, and $1,136 for the years ending
December 31, 1993, 1994 and 1995, respectively.
 
     At the date of termination of S Corporation status, the Company was
required to provide for a deferred tax liability for cumulative temporary
differences between financial reporting and tax reporting. Such deferred taxes
are based on the cumulative temporary difference at the date of termination of S
Corporation status. If the termination of S Corporation status had occurred at
December 31, 1995, the deferred income tax liability would have been $192. The
effect of recognizing the deferred taxes will be included in income from
continuing operations in the year of termination of S Corporation status.

RECAPITALIZATION AND INITIAL PUBLIC OFFERING
 
     On February 6, 1996, the Company completed an initial public offering of
3,900 shares of Common Stock and on February 20, 1996, the underwriters of the
offering fully exercised their over allotment option for an additional 585

exchanged 4,834 shares of Common Stock, plus cash, notes payable and the
assumption of certain debt for either stock or selected assets and liabilities
of KCI, NEI, Tyler, Kansas and Tennessee in accordance with executed combination
agreements. The exchange is being accounted for utilizing the historical cost
basis in accordance with Securities and Exchange Commission Staff Accounting

assets exchanged. Cash consideration given in these acquisitions is treated for
accounting purposes as a dividend from the Company to Tennessee and the four
unrelated businesses acquired to their owners.

Stock with the Securities and Exchange Commission on Form S-8 for the following

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors and Stockholders
Renal Care Group, Inc.
 
     We have audited the accompanying combined balance sheets of Renal Care
Group, Inc. (of Tennessee) and Three Unrelated Businesses to be Acquired, as
identified in Note 1, as of December 31, 1994 and 1995, and the related combined
statements of operations, changes and owners' equity and cash flows for each of
the three years in the period ended December 31, 1995. These financial
statements are the responsibility of the companies' management. Our
responsibility is to express an opinion on these financial statements based on
our audits. We did not audit the 1993 and 1994 financial statements of Tyler
Nephrology Associates, P.A. and the combined financial statements of Kansas
Nephrology Associates, P.A. and Kansas Dialysis Supply, Inc., which statements
reflect total assets constituting 57% as of December 31, 1994 and total revenues
constituting 68% for the two years in the period ended December 31 1994. Those
statements were audited by other auditors whose reports have been furnished to
us, and our opinion, insofar as it relates to data included for Tyler Nephrology
Associates, P.A. and the combined financial statements of Kansas Nephrology
Associates, P.A. and Kansas Dialysis Supply, Inc., is based solely on the
reports of the other auditors.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits and the reports of other auditors provide a
reasonable basis for our opinion.
 
     In our opinion, based on our audits and the reports of other auditors, the
financial statements referred to above present fairly, in all material respects,
the combined financial position of Renal Care Group, Inc. (of Tennessee) and
Three Unrelated Businesses to be Acquired at December 31, 1994 and 1995, and the
combined results of their operations and their cash flows for each of the three
years in the period ended December 31, 1995, in conformity with generally
accepted accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
                               DECEMBER 31, 1995
 
1.  ORGANIZATION AND BASIS OF PRESENTATION
 
     Renal Care Group, Inc. (of Delaware) ("the Company") was formed in June
1995, primarily for the purpose of acquiring four dialysis businesses and Renal
Care Group, Inc. (of Tennessee) ("Tennessee"), in exchange for shares of its
Common Stock, cash, notes payable and the assumption of certain debt (the
"Combination"). The Combination was effected in accordance with executed
combination agreements with the four dialysis businesses and Tennessee and
occurred concurrently with the closing of the initial public offering of the
Company (the "Offering") in February 1996. Kidney Care, Inc. and certain
operating divisions of Medical Enterprises, Ltd. and Health care Suppliers, Inc.
(collectively "KidneyCare") has been designated as the Predecessor and thus
KidneyCare's financial statements are not included in these combined financial
statements. The Three Unrelated Businesses to be Acquired, which comprise
numerous legal entities, conduct business as Northeast Indiana Kidney Center
("NEI"), Tyler Nephrology Associates, P.A. ("Tyler"), and Kansas Nephrology
Associates, P.A. ("KNA") and Kansas Dialysis Supply, Inc. ("KDS," and with KNA,
"Kansas"). Tennessee and Three Unrelated Businesses to be Acquired are based in
Tennessee, Indiana, Texas, and Kansas. Effective July 31, 1995, D.M.N.
Professional Corporation, which is owned by the physician owners of NEI, bought
the remaining 50% ownership interest in NEI from its former joint venture
partner (See Note 3). The joint venture which is NEI is included in these
combined financial statements.
 
     Physician services are provided to the Three Unrelated Businesses to be
Acquired by physician groups, which comprise shareholders, partners or legal
entities owned by shareholders or partners of the Three Unrelated Businesses to
be Acquired. Substantially all of the dialysis treatments performed by the Three
Unrelated Businesses to be Acquired are referred by these related physician
groups.
 
     Tennessee and the Three Unrelated Businesses to be Acquired previously have
operated as separate independent entities. Their historical financial positions,
results of operations and cash flows have been combined in the accompanying
financial statements and do not reflect any adjustments relating to the
Combination or the impacts that may have occurred if the operations of Tennessee
and the Three Unrelated Businesses to be Acquired had been combined. All
significant intercompany accounts and transactions have been eliminated.
 
     Two of the Three Unrelated Businesses to be Acquired maintain their books
and records on the cash basis of accounting. The accompanying financial
statements have been prepared on the accrual basis of accounting. These combined
financial statements have been prepared to show the combined operations and
combined financial position of Tennessee and Three Unrelated Businesses to be
Acquired. Certain entities are not required to pay federal or state income taxes
(due to their status as partnerships, S Corporations and corporations managed to
result in taxes being the responsibility of the respective owners), as further
described in Note 2.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
NET REVENUE
 
     Accounts receivable and net revenue are recorded at the estimated net
realizable amount from Medicare, Medicaid, patients, commercial insurers, and
other third-party payors for services rendered. The Medicare and Medicaid
programs reimburse Tennessee and Three Unrelated Businesses to be Acquired at
amounts that are different from the Company's established rates. Contractual
adjustments under these programs represent the
 
                                      F-26
<PAGE>   86
 
                   RENAL CARE GROUP, INC. (OF TENNESSEE) AND
                   THREE UNRELATED BUSINESSES TO BE ACQUIRED
 
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
difference between the amounts billed for these services and the amounts that
are reimbursable by third-party payors. A summary of the basis for reimbursement
with these payors follows:
 
  Medicare
 
          Tennessee and Three Unrelated Businesses to be Acquired are paid by
     the Medicare program on a prospective payment system for dialysis services.
     Each facility receives a composite rate that is adjusted to account for
     geographic differences in the cost of labor. The prospectively determined
     composite rates are not subject to retroactive adjustments.
 
  Medicaid
 
          Medicaid is a state administered program with reimbursements varying
     by state. The Medicaid programs administered by each of Indiana, Ohio,
     Texas, Kansas and Tennessee, reimburse Tennessee and the respective Three
     Unrelated Businesses to be Acquired.
 
  Other
 
          Other payments from patients, commercial insurers, and other
     third-party payors are received pursuant to a variety of reimbursement
     arrangements, which are generally higher than those payments received from
     the Medicare and Medicaid programs.
 
          The allowance for doubtful accounts represents management's estimate
     of potential credit losses associated with amounts due from patients,
     commercial insurers, and other third-party payors. Management of Tennessee
     and Three Unrelated Businesses to be Acquired does not believe that
     receivables from the Medicare and Medicaid programs represent any
     significant credit risk.
 
          Reimbursements from Medicare and Medicaid at established rates
     approximated 68%, 64%, and 69% of patient service revenue for the years
     ended December 31, 1993, 1994 and 1995, respectively.
 
CASH AND CASH EQUIVALENTS
 
     For the purpose of the combined statements of cash flows, cash and cash
equivalents include demand deposits and money market accounts at a financial
institution. All highly liquid investments with a maturity of three months or
less when purchased are considered to be cash equivalents. The carrying amount
reflected on the balance sheet at December 31, 1994 and 1995 is equal to
approximate fair value.
 
HELD-TO-MATURITY SECURITIES
 
     Management determines the appropriate classification of debt securities at
the time of purchase and reevaluates such designation as of each balance sheet
date. Debt securities are classified as held-to-maturity when there is the
positive intent and ability to hold the securities to maturity. Held-to-maturity
securities are stated at cost, adjusted for amortization of premium and
accretion of discount to maturity. Any such amortization is included in interest
income. Any interest received on securities classified as held-to-maturity is
included in interest income. All held-to-maturity securities mature within one
year of the balance sheet date.
 
INVENTORIES
 
     Inventories consist of dialysis supplies and are stated at the lower of
cost or market under the first-in, first-out method or market.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment are stated at cost and depreciated using the
straight-line method over the estimated useful lives of the assets. The general
range of useful lives is five to 40 years for buildings and leasehold
improvements (limited to the terms of the lease including expected renewal
periods), and five to
 
                                      F-27

                   THREE UNRELATED BUSINESSES TO BE ACQUIRED
 
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
15 years for furniture, fixtures and equipment. Routine maintenance and repairs
are expensed as incurred, while costs of betterments and renewals are
capitalized.
 
OTHER ASSETS
 
     Included in other assets are escrow deposits related to a performance
guarantee agreement between Kansas and a local hospital, which originated in
1986. Such agreement requires Kansas to deposit $8 per month with a designated
money manager until 1996, at which time Kansas will have unrestricted use of the
amounts deposited and any earnings thereon if it has fulfilled certain
obligations thereto. In the opinion of management of Kansas, the assets relating
to this guarantee are deemed fully collectible.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
INCOME TAXES
 
     The Three Unrelated Businesses to be Acquired are S Corporations or
partnerships; accordingly, income tax liabilities are the responsibility of the
respective owners or partners. Under these provisions, the Three Unrelated
Businesses to be Acquired generally do not pay corporate income taxes; rather
the income or loss is allocated to each stockholder for inclusion in their
respective income tax returns. Because of this practice, provisions for income
taxes and deferred tax assets and liabilities of these taxable entities have not
been reflected in these combined financial statements.
 
     Tennessee is a C Corporation and accounts for income taxes under the
liability method. Under this method, deferred tax assets and liabilities are
determined based upon differences between financial reporting and tax basis of
assets and liabilities and are measured using the enacted tax and laws that will
be in effect when the differences are expected to reverse.
 
ESTIMATED MEDICAL PROFESSIONAL LIABILITY CLAIMS
 
     Tennessee and each of the Three Unrelated Businesses to be Acquired are
insured for medical professional liability claims through retrospectively rated
commercial insurance policies. It is their respective policies that provision
for estimated premium adjustments to medical professional liability costs be
made for asserted and unasserted claims and based upon their experiences.
Provision for such professional liability claims includes estimates of the
ultimate costs of such claims. To date, their experiences with such claims has
not been significant. Accordingly, no such provision has been made.
 
OWNERS' EQUITY
 
     Owners' equity includes the respective capital stock, additional paid-in
capital, partnership capital, and retained earnings of the various legal
entities reflected herein. The Three Unrelated Businesses to be Acquired have
multiple owners, various types of agreements exist among the owners which call
for the transfer of a physician's ownership interest by the continuing owners in
the case of certain events such as the owner's retirement or death. Frequently,
the existing owners are required to pay the departed owner for his interest.
 
NEWLY ISSUED ACCOUNTING STANDARDS
 
     Tennessee and each of the Three Unrelated Businesses to be Acquired have
considered the impact of newly issued financial accounting pronouncements,
principally Statement of Financial Accounting Standards
 
                                      F-28

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of," and do not believe that adoption of this and any
other newly issued pronouncements would have a significant impact on the
combined financial statements.
 
3.  ACQUISITION OF PARTNERSHIP INTEREST
 
     Effective July 31, 1995, the 50% physician owners of NEI bought out the
remaining 50% ownership interest of its joint venture partner for $4,200, which
was paid from the proceeds of new debt. This transaction was accounted for using
purchase accounting which resulted in the recognition of approximately $2,900 of
goodwill which is being amortized over forty years.
 
4.  CASH, CASH EQUIVALENTS AND HELD-TO-MATURITY SECURITIES
 
     In May 1993, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 115, "Accounting for Certain Investments in
Debt and Equity Securities." Tennessee adopted the provisions of the new
standard for investments held as of or acquired after January 1, 1994. In
accordance with the Statement, prior period financial statements have not been
restated to reflect the change in accounting principle. There was no cumulative
effect of adopting Statement 115 as of January 1, 1994. The following is a
summary of cash, cash equivalents, and investments in held-to-maturity
securities as of:

contributions related to these plans totaling $251, $351 and $414 in 1993, 1994
and 1995, respectively.
 
     Tennessee and Three Unrelated Businesses to be Acquired do not typically
provide employees any post-retirement benefits other than pensions and,

9.  ADVANCES RECEIVED AND PREFERRED STOCK
 
     Tennessee is authorized to issue 1,000 shares of Preferred Stock at $.01
par value per share. Tennessee has designated as Series A Preferred Stock, 667
shares, $.01 par value per share. The remaining 333 shares of the Preferred
Stock may be issued from time to time in one or more series, each such series to
be so designated as to distinguish the shares from the shares of all other
series or classes. The Board of Directors has the authority to divide the
Preferred Stock into series and determine the preferences, limitations and
relative rights.
 
     The holders of the Series A Preferred Stock have voting rights and receive
dividends, if any, share for share, with Common Stock. The holders of Series A
Preferred Stock vote as a class with respect to amending the charter of
Tennessee, approving a consolidation or merger of Tennessee, changing the
preferences of the Series A Preferred Stock, and effecting an exchange of the
Series A Preferred Stock. The holders of Series A Preferred Stock have no
preferences with respect to dividends. The Series A Preferred Stock is
convertible into Common Stock and will receive a preference distribution equal
to its purchase price upon liquidation or sale of Tennessee. The holders shall
be entitled to a Preference Amount of $7.50. The number of shares of Common
Stock issuable will equal the result obtained by dividing the Preference Amount
by the Current Conversion Price. The Initial Conversion Price is set at $7.50
and shall be adjusted to the Current Conversion Price, as defined. In the event
of a public offering of Tennessee's Common Stock, the Series A Preferred Stock
will have the right to convert to Common Stock at anytime. In the event that
prior to May 6, 1999, Tennessee has neither sold shares in an initial public
offering nor effected a merger or consolidation, at the option of the holder of
Series A Preferred Stock, the shares become redeemable at $10.50 per share plus
an amount equal to $.0016438 per day for each day after May 6, 1999.
 
     In April and May 1994, Tennessee received $2,449, net of commissions and
legal fees of $51, relating to the subscription of Series A Preferred Stock. On
June 22, 1995, the stock was issued to the subscribers. Such proceeds are
classified as advances received at December 31, 1994 and as redeemable preferred
stock at December 31, 1995.

conversion price of $7.50 per share. The Company offered such securities solely
to "accredited investors" (as defined in Regulation D promulgated under the

                                 (IN THOUSANDS)
                                JANUARY 31, 1996
 
1. ORGANIZATION AND BASIS OF PRESENTATION
 
     Kidney Care, Inc., et al. ("Kidney Care") consists of Kidney Care, Inc.
("KC") and certain operating divisions of its affiliates, Medical Enterprises,
Ltd. ("MEL") and Health Care Suppliers, Inc. ("HSI"). Kidney Care operates
dialysis treatment centers and provides outpatient and home patient dialysis
services in the southern United States. The combined financial statements
present the operating results and financial position of the divisions of those
entities affiliated with KC that became part of a combination referred to in
Note 12. KC, MEL and HSI have common management and members of the Boards of
Directors. All significant intercompany transactions between KC and the
operating divisions of MEL and HSI have been eliminated in the combination.
 
     MEL and HSI provide various administrative services to Kidney Care
including data processing, accounting, personnel, purchasing and customer
service. It is Kidney Care's policy to charge the expenses of MEL and HSI first
on the basis of direct usage when identifiable, with the remainder allocated on
the basis of time spent by the service departments on Kidney Care matters.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Net Revenue
 
     Net revenue is recorded as services are rendered at established rates net
of contractual adjustments. During the years ended January 31, 1994, 1995, and
1996, Kidney Care received approximately 86% of its net revenue from Medicare
and Medicaid reimbursement programs which reimburse dialysis services on a
prospective payment system. Contractual adjustments arise due to the terms of
certain reimbursement and managed care contracts. Such adjustments represent the
difference between charges at established rates and estimated amounts to be
reimbursed to Kidney Care and are recognized when the services are rendered. Any
differences between estimated contractual adjustments and actual final
settlements under reimbursement contracts are recognized when the final
settlements are made.
 
     Kidney Care provides charity care to certain patients who are identified
based on financial information provided. Charity care patient service revenue,
which is not material, is recorded when payment is received.
 
  Cash and Cash Equivalents
 
     Cash equivalents are highly liquid investments with original maturity of
three months or less.
 
  Short-term Government Securities
 
     Short-term government securities are stated at cost, which approximates
market, and consist of U.S. Government agencies securities with maturities of
one year or less.
 
  Inventories
 
     Inventories are stated at cost (first-in, first-out method) and consist of
kidney dialysis supplies, drugs and raw materials and supplies used in the
production of dialysis concentrate.
 
  Depreciation and Amortization
 
     Depreciation and amortization are provided on the straight-line method over
the estimated useful lives of the assets which range from five to ten years for
furniture, fixtures and equipment and five to thirty-one years for leasehold
improvements and buildings. Repairs and maintenance costs are expensed as they
are incurred, while costs of betterments and renewals are capitalized.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Estimated Medical Professional Liability Claims
 
     Kidney Care is insured for medical professional liability claims through a
retrospectively rated commercial insurance policy. It is Kidney Care's policy
that provision for estimated premium adjustments to medical professional
liability costs be made for asserted and unasserted claims and based upon Kidney
Care's experience. Provision for such professional liability claims includes
estimates of the ultimate costs of such claims. To date, Kidney Care's
experience with such claims has not been significant. Accordingly, no such
provision has been made.
 
  Income Taxes
 
     KC is a not-for-profit corporation as described in Section 501(c)(3) of the
Internal Revenue Code, as amended (the "Code") and is exempt from federal and
state income taxes on related income pursuant to Section 501(a) of the Code.
Consequently, the accompanying combined statements of revenues, expenses and
changes in net assets do not include provisions for income taxes from KC's
operations. Income taxes have been provided by the liability method on earnings
of the operating divisions of MEL and HSI included therein in accordance with
the provisions of Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes."
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the dates of the financial
statements and the reported amounts of revenues and expenses during the reported
periods. Actual results could differ from those estimates.
 
3. ACCOUNTS RECEIVABLE
 
     Accounts receivable, net at January 31, 1995 and 1996 of $7,814 and $8,348,
respectively, includes an allowance for contractual adjustments of $9,284 and
$10,724, respectively, and an allowance for doubtful accounts of $2,616 and
$1,855, respectively.
 
4. RECOVERABLE SALES TAX
 
     On January 5, 1994, the Mississippi State Tax Commission principally
granted Kidney Care an exemption from Mississippi sales taxes. Kidney Care
recovered sales tax of $1,727 principally applicable to supply purchases from
February 1, 1990 through December 31, 1994. Supplies and drugs expense included
in patient care costs in the accompanying combined statements of revenues,
expenses and changes in net assets is included net of the sales taxes recovered
applicable to the respective fiscal years.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Kidney Care is involved from time to time in claims and routine litigation
in the normal course of its business. Management is of the opinion, based on the
advice of counsel, that the outcome of any matters presently pending will not
have a material adverse effect on the combined financial position or operations
of Kidney Care.
 
12. ASSET TRANSFER AGREEMENTS
 
     On July 31, 1995, KC entered into an agreement with Renal Care Group, Inc.
("RCG") whereby RCG agreed to purchase substantially all of KC's assets and
assume certain of KC's liabilities. On November 14, 1995, MEL entered into an
agreement with RCG whereby MEL agreed to be acquired by RCG in a merger, prior
to which MEL's assets that are unrelated to its dialysis business will be spun
off into a separate entity.
 
     Effective February 6, 1996, RCG completed an initial public offering of
3,900 shares of Common Stock. Simultaneous with the consummation of the
offering, a combination was consummated which included provisions for the
transfer agreements between RCG, KC and MEL described above.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Company's Amended and Restated Certificate of Incorporation provides
that the Company shall, to the fullest extent permitted by Section 145 of the
General Corporation Law of the State of Delaware, as amended from time to time,
indemnify its officers and directors.
 
     Section 145 of the General Corporation Law of the State of Delaware permits
a corporation, under specified circumstances, to indemnify its directors,
officers, employees or agents against expenses (including attorney's fees),
judgments, fines and amounts paid in settlements actually and reasonably
incurred by them in connection with any action, suit or proceeding brought by
third parties by reason of the fact that they were or are directors, officers,
employees or agents of the corporation, if such directors, officers, employees
or agents acted in good faith and in a manner they reasonably believed to be in
or not opposed to the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reason to believe their conduct was
unlawful. In a derivative action, i.e., one by or in the right of the
corporation, indemnification may be made only for expenses actually and
reasonably incurred by directors, officers, employees or agents in connection
with the defense or settlement of an action or suit, and only with respect to a
matter as to which they shall have acted in good faith and in a manner they
reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification shall be made if such person shall
have been adjudged liable to the corporation, unless and only to the extent that
the court in which the action or suit was brought shall determine upon
application that the defendant directors, officers, employees or agents are
fairly and reasonably entitled to indemnify for such expenses despite such
adjudication of liability.
 
     The Company's Amended and Restated Certificate of Incorporation contains a
provision which eliminates, to the fullest extent permitted by the General
Corporation Law of Delaware, director liability for monetary damages for
breaches of the fiduciary duty of care or any other duty as a director.
 
     Reference is hereby made to the Underwriting Agreement, the form of which
is filed as Exhibit 1.1 hereto, in which the Company agrees to indemnify the
Underwriters and certain other persons against certain civil liabilities.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES
 
     Since its incorporation on June 20, 1995, the Company has issued the
following securities:
 
          (A) On June 22, 1995, Sam A. Brooks purchased one share of Common
     Stock for $10.00. Such sale was made in reliance upon the exemption from
     registration contained in Section 4(2) of the Securities Act.
 
          (B) At various times between July 19, 1995, and November 4, 1995, the
     Company granted options to purchase 1,076,448 shares of Common Stock to
     various consultants, directors and officers of the Company. Such grants
     were made in reliance upon the exemption from registration contained in
     Section 4(2) of the Securities Act and Rule 701 as promulgated thereunder.
 
          (C) Between November 16, 1995 and December 8, 1995, the security
     holders of the Founding Companies made their investment decision to
     purchase 4,381,000 shares of Common Stock upon the closing of the initial
     public offering. Obtaining such investment decisions and the ultimate sale
     of such shares of Common Stock at the closing of the initial public
     offering were made in reliance upon the exemption from registration set
     forth in Section 4(2) of the Securities Act. Such shares of Common Stock
     (along with certain cash payments and assumptions of liabilities by the
     Company) were issued in exchange for the Founding Companies as described in
     "The Company" and "Certain Transactions."
 
          (D) On December 7, 1995, the Company sold an aggregate principal
     amount of $1,380,000 of Convertible Senior Subordinated Promissory Notes to
     17 owners of certain of the Founding Companies in a private placement
     pursuant to the exemption from registration set forth in Section 4(2) of
     the Securities Act. Such notes bear interest at a rate of 7.0% per annum,
     mature on December 7, 1996, and the principal and accrued interest thereon
     are convertible into shares of Common Stock of the Company at a conversion
     price of $7.50 per share.
 
          (E) On February 12, 1996, the Company issued 4,381,000 shares of
     Common Stock to the former owners of the Founding Companies in a private
     placement pursuant to the exemption from registration set forth in Section
     4(2) of the Securities Act.
 
          (F) On April 26, 1996, the Company issued 528,245 shares of Common
     Stock to the former owners of Main Line Suburban Dialysis Centers, Inc. in
     a private placement pursuant to the exemption from registration set forth
     in Section 4(2) of the Securities Act.
 
          (G) On July 1, 1996, the Company issued 298,775 shares of Common Stock
     to the former owners of The Nephrology Centers, Inc. in a private placement
     pursuant to the exemption from registration set forth in Section 4(2) of
     the Securities Act.
 
          (H) On September 30, 1996, the Company issued 2,400,000 shares of
     Common Stock to the former owners of RenalWest, L.C. in a private placement
     pursuant to the exemption from registration set forth in Section 4(2) of
     the Securities Act.
 
          (I) On September 30, 1996, the Company issued 70,000 shares of Common
     Stock to the former owner of Northeast Alabama Kidney Center, Inc. in a
     private placement pursuant to the exemption from registration set forth in
     Section 4(2) of the Securities Act.
 
     No underwriters were engaged in connection with the foregoing sales of
securities.

ITEM 17.  UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company 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 of
1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the Company
of expenses incurred or paid by a director, officer or controlling person of the
Company in the
 
                                      II-4

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 Company 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 of 1933 and will be governed by the
final adjudication of such issue.
 
     The Company hereby undertakes to provide to the Representative of the
Underwriters at the closing specified in the underwriting agreements
certificates in such denominations and registered in such names as required by
the Representative of the Underwriters to permit prompt delivery to each
purchaser.
 
     The Company hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part
     of this Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus 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.

1994 and 1995 and for each of the three years in the period ended December 31,
1995, and have issued our report thereon dated September 30, 1996 (included

financial statement schedule listed in Item 16(b) of this Registration

Kansas Dialysis Supply, Inc. which statements reflect total assets constituting
57% as of December 31, 1994 and total revenues constituting 68% for the two
years in the period ended December 31, 1994. We have been furnished with the
report of other auditors with respect to Schedule II of Renal Care Group, Inc.

     In our opinion, based on our audits and the reports of other auditors, the

all material respects the information set forth therein.

                          AGREEMENT AND PLAN OF MERGER


     THIS AGREEMENT AND PLAN OF MERGER (this "Agreement") is made and entered
into as of August 7, 1996, by and among RENAL CARE GROUP, INC. ("RCG"), a
Delaware corporation; RCG THREE CORP. ("RCG Three"), an Arizona corporation,
RCG NINE CORP. ("RCG Nine"), an Arizona corporation, RCG FOUR CORP. ("RCG
Four"), an Arizona corporation; RENALWEST, L.C., an Arizona limited liability
company ("RenalWest"); 3-CO., Inc., an Arizona corporation ("Three Co"); 9-CO.,
Inc., an Arizona corporation ("Nine Co"), 4-CO., Inc., an Arizona corporation
("Four Co"), and those parties listed on the signature pages hereto as the
shareholders of  Three Co,  Nine Co and Four Co (the "Owners") (RCG Three,  RCG
Nine, and RCG Four together the "Merger Corps" and individually a "Merger
Corp.;" Three Co.,  Nine Co. and Four Co together the "Members" and
individually a "Member"; the Members and RenalWest together the "Companies" and
individually a "Company").


                                    PREAMBLE

     The Merger Corps are wholly-owned subsidiaries of RCG and the Members are
the sole owners of RenalWest.  The Boards of Directors of RCG, the Merger
Corps, and the Members, and RenalWest and the Owners are of the opinion that
the transactions described herein are in the best interests of the parties and
their respective shareholders, as applicable.  This Agreement provides for the
acquisition of the Companies by RCG pursuant to the simultaneous mergers of (i)
RCG Three with and into Three Co, (ii) RCG Nine with and into Nine Co and (iii)
RCG Four with and into Four Co.  At the Effective Time of such mergers, the
outstanding shares of the capital stock of each of Three Co,  Nine Co and Four
Co shall be converted into the right to receive shares of the common stock of
RCG (except as provided herein).  As a result, the Owners shall become
shareholders of RCG and each of Three Co,  Nine Co and Four Co shall continue
to conduct its business and operations as a wholly owned subsidiary of RCG, and
RenalWest shall continue to be owned by Three Co,  Nine Co and Four Co.  It is
the intention of the parties to this Agreement that the mergers qualify (i) as
a "reorganization" within the meaning of Section 368(a) of the Code for federal
income tax purposes, and (ii) for treatment as a pooling of interests for
accounting purposes.

     Certain terms used in this Agreement are defined in Article 14 of this
Agreement.

     NOW, THEREFORE, in consideration of the above and the mutual warranties,
representations, covenants and agreements set forth herein, the parties agree
as follows:

of Three Co,  Nine Co and Four Co shall be the Surviving Corporation resulting
from the Mergers and shall continue in existence as a wholly owned Subsidiary
of RCG and shall continue to be governed by the Laws of the State of Arizona.
The Mergers shall be consummated pursuant to the terms of this Agreement, which
has been approved and adopted by the respective Boards of Directors of RCG, the
Merger Corps and the Members.

immediately prior to the Effective Time shall be amended and restated,

     3.1 Conversion of Shares.  Subject to the provisions of this Article 3, at
the Effective Time, by virtue of the Mergers and without any action on the part
of the parties hereto or the shareholders of any of the parties, the shares of
the constituent corporations of the Mergers shall be converted as follows:

     (a) Each share of each Merger Corp. Common Stock issued and outstanding at

2,400,000 shares of RCG Common Stock to be distributed to Owners as set forth
on Schedule 3.1(b) hereto (the "Merger Consideration").

     3.2 Anti-Dilution Provisions.  In the event RCG changes the number of
shares of RCG Common Stock issued and outstanding prior to the Effective Time
as a result of a stock split, stock dividend, combination of shares or other
similar recapitalization with respect to such stock (an "Anti-Dilution Event")
and the record date therefor or, if there is no record date, the effective date
thereof, shall be prior to the Effective Time, then the Average Trading Prices
and the numbers of shares specified in Section 3.1 shall be adjusted to
appropriately and proportionately adjust the number of shares of RCG Common
Stock into which the shares of Member Common Stock will be converted pursuant
to Section 3.1.

     3.3 Shares Held by the Company.  Each share of Member Common Stock held in
treasury by the Members, shall be canceled and retired at the Effective Time
and no consideration shall be issued in exchange therefor.

fraction is less than .5.


                                   ARTICLE 4

specify that delivery shall be effected, and risk of loss and title to the
certificates theretofore representing shares of Member Common Stock shall pass,
only upon proper delivery of such certificates to the Exchange Agent).  After
the Effective Time, each holder of shares of Member Common Stock (other than
shares to be canceled pursuant to Section 3.3 of this Agreement) issued and
outstanding at the Effective Time shall surrender the certificate or
certificates representing such shares to the Exchange Agent and shall promptly
upon surrender thereof receive in exchange therefor the consideration provided
in Section 3.1 of this Agreement.  RCG shall not be obligated to deliver the
consideration to which any former holder of Member Common Stock is entitled as
a result of the Merger until such holder surrenders his certificate or
certificates representing the shares of Member Common Stock for exchange as
provided in this Section 4.1 or such holder provides an appropriate affidavit
regarding loss of such certificate and an indemnification for loss in favor of
RCG.  The certificate or certificates of Member Common Stock so surrendered
shall be duly endorsed as the Exchange Agent may require.  Any other provision
of this Agreement notwithstanding, neither RCG, the Surviving Corporation nor
the Exchange Agent shall be liable to a holder of Member Common Stock for any
amounts paid or property delivered in good faith to a public official pursuant
to any applicable abandoned property Law.

     4.2 Rights of Former Member Shareholders.  At the Effective Time, the
stock transfer books of the Members shall be closed and no transfer of Member
Common Stock by any such holder shall thereafter be made or recognized.  Until
surrendered in accordance with the provisions of Section 4.1 of this Agreement,
each certificate theretofore representing shares of Member Common Stock (other
than shares to be canceled pursuant to Section 3.3 of this Agreement) shall
from and after the Effective Time represent for all purposes only the right to
receive the consideration provided in Section 3.1 of this Agreement in exchange
therefor.  To the extent permitted by Law, former shareholders of record of the
Members shall be entitled to vote after the Effective Time at any meeting of
RCG shareholders the number of whole shares of RCG Common Stock into which
their respective shares of Member Common Stock are converted.  Whenever a
dividend or other distribution is declared by RCG on the RCG Common Stock, the
record date for which is at or after the Effective Time, the declaration shall
include dividends or other distributions on all shares issuable pursuant to
this Agreement, but no dividend or other distribution payable to the holders of
record of RCG Common Stock as of any time subsequent to the Effective Time
shall be delivered to the holder of any certificate representing shares of
Member Common Stock issued and outstanding at the Effective Time until such
holder surrenders such certificate for exchange as provided in Section 4.1 of
this Agreement.  However, upon surrender of such certificate, the RCG Common
Stock certificate (together with all such undelivered dividends or other
distributions without interest) shall be delivered and paid with respect to
each share represented by such certificate.

     The foregoing documents together with the exhibits thereto (which will be

the "RCG Documents."  The RCG Documents include accurate and complete copies of
each and every (i) report and registration statement filed with the SEC ("SEC
Documents") and (ii) publicly disseminated press release of RCG during the past
twelve months ("Press Releases").  As of the time each SEC Document was filed
with the SEC, such SEC Document did not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.

     7.9 Absence of Changes.  Except as set forth on Schedule 7.9, since March
31, 1996 (the date of last financial statements), RCG has not suffered any
material adverse change in its working capital, condition (financial or
otherwise), assets, liabilities, reserves, business or operations.

     7.10 No Undisclosed Liabilities.  Except as listed on Schedule 7.10, and
except for liabilities and obligations reflected in the most recent financial
statements of RCG contained in the RCG Documents or incurred in the ordinary
course of its business since the date of RCG's most recent balance sheet
included in the RCG Documents, RCG has no material liabilities or obligations,
whether accrued, absolute, contingent or otherwise.

     7.11. No Liabilities of Merger Corps.  Except for the obligations
hereunder, the Merger Corps. are not subject to any liabilities, obligations or
claims, whether accrued, absolute, contingent, liquidated or unliquidated, or
otherwise.  Each Merger Corp. was formed solely for the purpose of consummating
the Mergers contemplated by this Agreement and each Merger Corp. has not
engaged in any business or other activity for any other purpose.

     7.12 Compliance with Legal Requirements.  To the knowledge of RCG, RCG and
each Merger Corp. are in compliance with all applicable legal requirements,
except where the failure to comply with such legal requirements has not had and
could not reasonably be expected to have a material adverse effect on RCG or
the Company.  RCG has not received any notice or any communication from any
governmental authority regarding any actual or possible violation of, or
failure to comply with, any legal requirement, except where failure to comply
with such legal requirement has not had and could not reasonably be expected to
have a material adverse effect on RCG.

     7.13 Employee Benefits.  RCG agrees that after the Mergers it will cause
the Members to cause RenalWest to credit RenalWest employees with service for
eligibility and vesting purposes, as applicable, 


                                   - 19 -

<PAGE>   21


under the benefit plans in which they participate after the Closing Date 
and that such employees will receive such RCG benefits as are provided to
similarly situated employees of RCG.

     7.14 Taxes.  (a)  Except as reflected in RCG's financial statements
included in the RCG Documents (the "RCG Financial Statements"), there does not
exist any material liability for taxes that may be asserted by any taxing
authority against, and no lien or other encumbrance for any such taxes will
attach to, RCG, any subsidiary ("Subsidiary") of RCG, or any assets of RCG or
any Subsidiary, other than taxes due in respect of periods for which tax
returns are not yet due and for which adequate accruals have been made in the
RCG Financial Statements.  All federal, foreign, state, county, and local tax
returns and tax reports required to be filed prior to the date hereof with
respect to RCG or any Subsidiary have been timely filed (other than returns for
which extensions to file have been granted) with the appropriate governmental
agencies in all jurisdictions in which such returns and reports are required to
be filed, all of which are true, correct, and complete, and all amounts shown
as owing thereon have been timely paid.

     (b) Neither RCG nor any Subsidiary has received notice of any tax claims
being asserted or any proposed assessment by any taxing authority and neither
RCG nor any Subsidiary is presently under, nor has received notice of, any
contemplated investigation or audit by the IRS or any other taxing authority
concerning any fiscal year or period ended prior to the date hereof.  Neither
RCG nor any Subsidiary has executed any extensions or waivers of any statute of
limitations on the assessment or collection of any tax due that is currently in
effect.

     (c) RCG and each Subsidiary, as well as any of their predecessors in
interest, have withheld or collected from each payment made to each of their
employees the amount of all taxes required to be withheld or collected
therefrom and have paid the same to the proper tax depositories or collecting
authorities.

     (d) Neither RCG nor any Subsidiary is or has ever been an includible
corporation in an affiliated group of corporations, within the meaning of
Section 1504 of the Code, other than in the affiliated group of which RCG is
the common parent corporation.

     (e) Neither RCG nor any Subsidiary is now or has ever been a party to any
tax-sharing agreements or similar arrangements, other than with respect to the
federal income tax returns for the affiliated group of which RCG is the common
parent corporation.

     (f) For purposes hereof, "tax" or "taxes" shall have the meaning
prescribed for "taxes" in section 5.19(g) of this Agreement.

     (g) RCG has no intention to cause or permit the liquidation or merging out
of existence of the Members.

     (h) RCG has no intention following the Mergers to sell or otherwise
dispose of its ownership of the Members, except for transfers of stock to
corporations controlled by RCG, as "control" is defined in section 368(c) of
the Code, or to cause the Members to sell or otherwise dispose of any of their
assets or of any of the assets acquired from any of the Merger Corps, except
for dispositions made in the ordinary course of business or transfers of assets
to a corporation controlled by RCG, as "control" is defined in section 368(c)
of the Code.

     (i) Except as disclosed on Schedule 7.14, there is no liability for taxes
on the part of RCG or any Subsidiary (excluding transactions for which the
financial reporting gain would exceed applicable income tax liability related
to such transaction) (i) that will arise with respect to a current or a future
taxable period, (ii) that is wholly or partly a consequence of a transaction or
occurrence, or transactions or occurrences, one or more of which occurred
before the date hereof, and (iii) that is not fully reserved on the RCG
Financial Statements.  In addition, except as disclosed on Schedule 7.14, there
are no

joint venture, partnership or other arrangements or contracts to which
RCG or any Subsidiary is a party and that could be treated as a partnership for
federal income tax purposes.

        (iv) take any action, or omit to take any action, which would cause any

     8.7 Confidentiality, Public Announcements.  The parties hereby affirm and
ratify the terms of that certain letter agreement, dated June 27, 1996, among
them concerning confidentiality, public announcements and related matters,
which agreement remains valid and binding among the parties notwithstanding
Section 15.9 hereof.

     8.8 Confidentiality, Noncompetition and Nonsolicitation.  (a)  Each Owner
agrees that, for a period of ten (10) years after the Effective Time, Owner
will not in any manner, directly or indirectly, by himself or herself or in
conjunction with any other person, conduct activities that are competitive with
the business of the Companies or acquire, establish or own any financial,
beneficial or other interest in (other than an interest consisting of less than
one percent (1%) of a class of publicly traded security), make any loan to or
for the benefit of, or render any managerial, marketing or other business
advice, to any entity that is then conducting activities that are competitive
with the business of the Companies, in either case within a geographic
territory defined as the seventy-five (75) mile radius of the Companies'
current locations (the "Territory").  For purposes of this Section the
"business of the Companies" shall mean owning or operating a renal dialysis
center, unit or facility or providing renal dialysis supplies or services to
any other center, unit or facility or any acute care facility or any home renal
dialysis patient, including the provision of pharmaceuticals or laboratory
services.

     (b) Each Owner further agrees that, for a period of ten (10) years after
the Effective Time, Owner will keep confidential and not directly or indirectly
divulge to anyone or use or otherwise appropriate for Owner's own benefit or
for the benefit of others, any knowledge or information of a confidential
nature with respect to the business of the Companies, RCG, or any of their
affiliates, including all trade secrets, pricing information, marketing
information or technical information (hereinafter referred to as the
"Confidential Data"), except for (i) a disclosure that is required by law; or
(ii) information that has been made generally available to the public by the
act of one who has the right to disclose such information.   Each Owner hereby
acknowledges and agrees that the prohibitions against disclosure of
Confidential Data recited herein are in addition to, and not in lieu of, any
rights or remedies which RCG may have available pursuant to the laws of any
jurisdiction or at common law to prevent the disclosure of confidential
information, and the enforcement by RCG of its rights and remedies pursuant
hereto shall not be construed as a waiver of any other rights or available
remedies which RCG may possess in law or equity.  Each Owner acknowledges that
RCG has taken reasonable and appropriate steps to ensure the confidentiality
and non-disclosure of all such Confidential Data.

     (c) Each Owner also agrees that, for a period of ten (10) years after the
Effective Time, Owner will not, for his or her own benefit or the benefit of
others, solicit any person or entity that has 


                                     - 25 -



<PAGE>   27


had, or disrupt or attempt to disrupt, any relationship, contractual or
otherwise (including with any patient, payor, physician, provider, managed care
organization or supplier), with RCG or any of its affiliates (including the
Companies), for the purpose of assisting, or creating such a relationship for,
any business entity that is conducting activities competitive with the business
of the Companies within the Territory.

     (d) Each Owner further agrees that, for a period of ten (10) years after
the Effective Time, Owner shall not induce, nor attempt to induce, any employee
of RCG, or any of its affiliates (including the Companies), to terminate his or
her association with any such party.

     (e) The covenants contained in this Section 8.8 are considered by the
parties hereto to be fair, reasonable and necessary for the protection of RCG
and the Companies.  The parties mutually agree that if a violation of any
covenant contained in this Section 8.8 occurs, such violation or threatened
violation will cause irreparable injury to RCG and the Companies and the remedy
at law for any such violation or threatened violation will be inadequate.  Each
Owner therefore agrees that RCG shall be entitled to appropriate equitable
relief, including but not limited to a temporary restraining order or a
preliminary injunction, in addition to any other remedy that might be available
at law or in equity.

     (f) Nothing in this Section 8.8 shall be deemed to prohibit any Owner who
is a physician from exercising his or her medical judgment concerning the
treatment of his or her patient in any manner whatsoever in any location
whatsoever, and shall not be deemed to require the referral of any such patient
to any facility of RCG  or any of its affiliates.

     (g) The foregoing ten (10) year periods in this Section 8.8 are subject to
RCG obtaining from its physician stockholders owning at least sixty percent
(60%) of the RCG Common Stock issued to its physician stockholders in
connection with the acquisition by RCG of their dialysis centers (the "Required
Physicians"), revisions where needed to similar agreements with such Required
Physician extending their corresponding periods of coverage to ten (10) years
from their original starting date.  In the event that the Required Physicians
are not subject to such ten year periods prior to or at the Closing, then the
foregoing ten (10) year periods in this Section 8.8 shall be reduced to the
longest corresponding period of time to which the Required Physicians are or
become subject.

     8.9 Medical Director Agreements.  The parties hereto agree that the
Company and each affiliated physician practice that has a physician member or
employee involved with the use, operation of or referral of patients to the
Company's dialysis facilities (the "Practices"), shall enter into a Medical
Director Agreement at Closing under which the Practices shall provide medical
director services to the Company for the dialysis facilities operated by the
Company.  Such Medical Director Agreement shall have an initial term of seven
(7) years with renewal terms for additional three year periods and shall
provide for (i) an aggregate annual fee to be paid by RCG to the Practices of
$840,000 (subject to agreed upon modifications) to be divided among the
Practices at the Practices' discretion, (ii) certain restrictive covenants,
including but not limited to a covenant not to compete with a duration of the
term of the Medical Director Agreement and three (3) years after termination of
the Medical Director Agreement, and (iii) other customary terms and conditions.
The Owners agree that a Medical Director Agreement substantially in the form
of Exhibit 8.9 attached hereto will be entered into at the Closing by them and
their practices.

     8.10 Right of First Refusal.  The Owners recognize the opportunities to
provide care for End Stage Renal Disease in an integrated manner and agree to
work in good faith with RCG to pursue opportunities for RCG and its affiliates
to offer the full range of dialysis services, including physician and
transplant services, to payors, health maintenance and other managed care
organizations.  Furthermore, the Owners agree to work in good faith with RCG or
any of its affiliates for the provision of medical director services for
dialysis treatment and for the provision of nephrology physician services at
the facilities of RCG acquired from or operated through the Company after the
Closing, and agree that for a period of three years from the Closing Date, the
Owners will allow RCG to have a right of first refusal with respect to any
proposed contract or other arrangement with a third party for the sale or
management of the Owner's medical practice on the same terms and conditions as
proposed by such third party, provided that such offer 


                                   - 26 -


<PAGE>   28

specified in paragraph (d) of Rule 144 under the 1933 Act with respect to the
Registrable Securities, as said Rule may be amended after the date hereof.

Owners and their transferees as defined in this Agreement) proposing to
distribute their Registrable Securities shall be prevented from including at
least eighty percent (80%) of the Registrable Securities proposed to be
distributed by them, then RCG shall be obligated to effect one (1) additional
demand registration pursuant to Section 1.2 upon the request of Holders.

        (vi) Notwithstanding Section 1.3 of Appendix A, the Holders shall have
the right to include up to forty percent (40%) of their aggregate Registrable

assignee of Registrable Securities, provided that RCG is given written notice
by such Holder at the time of or within a reasonable time of after such
transfer, stating the name and address of said transferee or assignee and
identifying the Registrable Securities with respect to which such registration
rights are being assigned.  Any transferee shall, as a condition of such
transfer, agree that all transferred Registrable Securities are subject to the
terms, conditions, provisions and agreement of this Agreement.

reporting requirements described in Section 8.14 in a manner to enable the
Owners to participate in the Secondary Offering described above and to take
other reasonable and appropriate actions to enable the owners to participate in
such Secondary Offering.  In the event that such Secondary Offering occurs and
the Owners are not able to participate through no fault of them or the
Companies, then RCG agrees to provide reasonable assistance to the Owners to
aid them in obtaining a loan or loans from a third party (such loan secured by
an adequate amount of their shares of Common Stock) until June 30, 1997 (the
"Maturity Date"), including, if necessary, a guaranty by RCG to such third
party lender of up to an aggregate of $1,500,000 of such loan or loans (such
guaranty by RCG to be secured by an adequate number of the Owners' shares of
RCG Common Stock and allocated among such Owner loans at their discretion).  If
such loan or loans are not available on terms and conditions otherwise
reasonably acceptable to the Owners, RCG agrees to provide a loan or loans
directly to the Owners of up to an aggregate amount of $1,500,000 (to be
allocated among the Owners at their discretion) which (i) mature on the
Maturity Date (ii) contain terms and

conditions to the Owners no less favorable than are available to RCG
from its third party lenders, and (iii) are secured by an adequate number of
shares of RCG Common Stock.  Either of the loan or loans described in this
Section 13.1(d) shall be paid prior to the Maturity Date to the extent of the
first available proceeds from any resale of the Owner's shares of RCG Common
Stock under the registration rights provided herein.

                             EMPLOYMENT AGREEMENT


     THIS AGREEMENT is made and entered into as of February 6, 1996, by and
between RENAL CARE GROUP, INC., a Delaware corporation (the "Company"), and RON
HINDS (hereinafter "Employee").


                                 WITNESSETH:

     
     WHEREAS, the Company desires to employ Employee, and Employee desires to
be employed by the Company, on the terms and conditions contained herein; and

     WHEREAS, in serving as an employee of the Company, Employee has and will
participate in the use and development of confidential proprietary information
about the Company, its customers and suppliers, and the methods used by the
Company and its employees in competition with other companies, as to which the
Company desires to protect fully its rights; and

     WHEREAS, the Company wishes to enter into an agreement with Employee
whereby Employee shall agree not to compete with the Company in any current or
future business activity conducted or entered into by the Company and to hold
certain information obtained by and through Employee's employment in
confidence.

     NOW, THEREFORE, in consideration of the compensation payable to Employee
by the Company pursuant to this Agreement, and the mutual promises, covenants,
representations and warranties contained herein, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto do agree as follows:

     1.  Employment.

         Effective on February 6, 1996, the Company hereby employs Employee, and
Employee hereby agrees to accept employment with the Company, upon the terms and
conditions hereinafter set forth.

     2.  Term.

         This Agreement shall begin on February 6, 1996 (the "Effective Date"),
and shall continue for an initial period of thirty-six (36) months (the
"Initial Period"), subject to earlier termination by employee or the Company as
hereinafter provided.  This Agreement shall renew for additional terms of
twelve (12) months each, subject to earlier termination hereinafter provided,
on the same terms and conditions (subject to mutually agreeable modifications,
if any).

       3.     Compensation and Benefits

              (a)    Base Compensation: The Company shall pay Employee an annual
salary of One Hundred Seventy-Five Thousand Dollars ($175,000), as may be
adjusted as provided herein (the "Base Compensation"), payable according to the
pay periods of the Company as may be in effect from time to time.  Such payment
shall be prorated for periods less than a full pay period.  The Base
Compensation shall be subject to withholding for federal, state and local
payroll and all other taxes or withholdings applicable to Employee.  Any
increase of the Base Compensation shall be at the discretion of the Company,
provided that any decreases to the then current Base Compensation shall require
the consent of the Employee.

              (b)    Benefits:  During the term of this Agreement, Employee
shall also be entitled to participate in the insurance and other fringe benefits
made available generally to similar employees of the Company, as such benefits
may be determined from time to time by the Company, provided that Employee shall
have at least four (4) weeks of paid vacation time.

              (c)    Bonuses:  In addition to the Base Compensation payable to
the Employee pursuant to the Section 3(a) above, from time to time Employees may
be entitled to an annual bonus as determined in the sole discretion of the
Company.

              (d)    Expenses:  The Company shall reimburse Employee for any and
all expenses reasonably incurred by employee incident to the performance of the
duties imposed upon Employee hereunder.

       4.     Duties, Extent of Services.

              Employee is engaged as Executive Vice President and Chief
Financial Officer and shall perform such duties and responsibilities as are
typically incident thereto, and shall perform in a faithful and competent manner
such additional duties as may be reasonably assigned from time to time by the
Company.  Such duties shall be performed on a full-time basis for the Company at
the Company's offices in Nashville, Tennessee.  Employee may be required, from
time to time, to perform his duties temporarily hereunder at such other place or
places as the Company shall reasonably require, provided that such period does
not exceed thirty (30) consecutive days without Employee's consent and that
during any such period Employee is able to return to Nashville, Tennessee at the
Company's expense for weekends.

       Employee shall devote all of Employee's business time, attention,
knowledge, and skill solely to the business and interest of the Company, and the
Company shall be entitled to all the benefits, profits, and other issues arising
from, or incident to, all work, services, and advice of Employee.

       5.     Termination.

              This Agreement may be terminated by the parties in the manners
specified below:

              (a)    Termination without Cause.  Either the Company or the
employee may terminate Employee's employment under this Agreement at any time
for any reason upon thirty (30) day's prior written notice to the other party.

              (b)    Termination for Cause.

                     The Company may terminate this Agreement on written notice
at any time for "cause".  For purposes of this Agreement, "cause" shall mean:
(i) Employee is convicted of, pleads guilty to, or confesses to a felony or any
crime involving any act of dishonesty, fraud, misappropriation, embezzlement or
moral turpitude, in which event the Company may terminate this Agreement
immediately, (ii) the misconduct or gross negligence by Employee in connection
with the performance of Employee's duties hereunder, (iii) the engaging by
Employee in any fraudulent, disloyal or unprofessional conduct which results in
an injury to the Company, its affiliates or any of its or their centers,
monetarily or otherwise, (iv) Employee breaches any provision of Section 6 of
this Agreement, or (v) the failure by Employee to otherwise substantially
perform his duties with the Company (other than any such failure resulting from
the disability of Employee under Section 5(c)(i)) or the breach of any provision
of this Agreement other than Section 6.  In the event of any termination for
cause pursuant to the provisions of (ii), (iii), (iv) or (v) of this subsection,
the Company shall give Employee written notice prior to such termination
detailing the specific acts, actions, failures, or events upon which the
forecast termination is based, and Employee shall have fifteen (15) days after
such written notice to cease such actions or otherwise correct any such failure
or breach.  If Employee does not cease such action or otherwise correct such
failure or breach within such fifteen day time period, or having once received
such written notice and ceased such actions or corrected such failure or breach,
Employee at any time thereafter again so acts, fails or breaches, the Company
may terminate this Agreement immediately.

              (c)    Involuntary Termination.

                     The employment of Employee hereunder shall be automatically
terminated by the death or disability of Employee as outlined below.

                     (i)    Disability.  The Company may terminate this
Agreement at the time Employee shall have been Disabled for a continuous period
of six (6) months during any continuous twelve month period.  For purposes of
this Paragraph 5(c)(i), the term "Disabled" shall mean Employee's inability to
perform the essential functions of his duties, with or without reasonable
accommodation.  During Employee's six month period of Disability or such longer
wait period as may be provided for in any policy of disability that may be
maintained by the Company for the benefit of Employee, the Company agrees to
continue to pay Employee's Base


                                       3
<PAGE>   4
Compensation (less regular withholdings for payroll or other taxes and other
required or proper items, and less any payments from all disability plans
provided by the Company).  In the event of a termination of Employee on account
of Disability, however, the Company shall be obligated to pay only Employee's
Base Compensation that has been earned through the effective date of termination
(less regular withholdings for payroll or other taxes and other required or
proper times, and less any payments from all disability plans provided by the
Company).

                     (ii)   Death.  In the event Employee shall die during the
term of this Agreement, this Agreement shall terminate and Employee's estate
shall receive the remainder of the Base Compensation set forth in Section 3(a)
hereof accrued to the last day of the month in which death occurs.

              (d)    Post-Termination Compensation.  Except as provided in
Section 5(c) above, upon termination of this Agreement, the Company shall be
relieved of all of its obligations hereunder notwithstanding any period of time
remaining under the initial or any renewal term, subject to the following:

                     (i)    Termination without Cause.  In the event that the
Company terminates Employee's employment hereunder without Cause under Section
5(a) above, then Employee shall, after the effective date of such termination,
as Employee's sole and exclusive remedy, receive the Base Compensation (as then
in effect) for a period of twelve (12) months after the termination date.  If
the Employee's employment is terminated by the Company without Cause, the
Employee shall be under no duty to seek or accept other employment; but if he
shall do so, any compensation he shall receive therefrom shall not diminish the
Company's obligation to make payments required to the Employee hereunder.  In
the event that Employee terminates his or her employment under Section 5(a)
above, the Company's obligation to pay Employee's Base Compensation shall
terminate as of the date of termination.

                     (ii)   Termination for Cause.  In the event that the
Company terminates Employee's employment hereunder with Cause under Section 5(b)
above, then Employee shall, after the effective date of such termination, as
Employee's sole and exclusive remedy, receive the Base Compensation (as then in
effect) for a period of one (1) month after the termination date.

                     (iii)  Termination following Change in Control.  If within
twelve (12) months following a Change in Control (as defined below), either (A)
the Company terminates the employment of Employee hereunder without Cause under
Section 5(a) above or (B) Employee resigns from a declined reassignment of a job
that is not reasonably equivalent in responsibility or compensation or that is
not in the same geographical area, then, in lieu of any other compensation that
may be specified herein, Employee shall continue to receive the Base
Compensation (as then in effect) for a period of thirty-six (36) months from the
date of termination payable in the same manner as it was being paid as of the
date of termination, provided, however, that the salary payment provided for
hereunder may at the option of the Company be paid in a single lump-sum payment,
to be paid not later than thirty (30) days after termination.  In the event such
payment obligation arises, no compensation received from other


                                       4
<PAGE>   5
employment (or otherwise) shall reduce the obligation to make the payment(s)
described in this paragraph.

              (e)    Change in Control.  "Change in Control" means a change in
control of the Company of a nature that would be required to be reported
(assuming such event has not been "previously reported") in response to Item
1(a) of a Current Report on Form 8-K pursuant to Section 13 of 15(d) of the
Exchange Act of 1934 (the "Exchange Act"); provided that, without limitation, a
Change in Control shall also be deemed to have occurred at such time as:

                     (i)    any "person" within the meaning of Section 14(d) of
the Exchange Act, other than the Company; a subsidiary, or any employee benefit
plan(s) sponsored by the Company or any Subsidiary, is or has become the
"beneficial owner," as defined in rule 13d-3 under the Exchange Act, directly or
indirectly, of 25% or more of the combined voting power of the outstanding
securities of the Company ordinarily having the right to vote at the election of
directors, or

                     (ii)   individuals who constitute the Board immediately
prior to any meeting of stockholders (the "Incumbent Board") have ceased for any
reason to constitute at least a majority thereof, provided that any person
becoming a director whose election, or nomination for election by the Company's
stockholders, was approved by a vote of at least three-quarters (3/4) of the
directors comprising the Incumbent Board (either by a specific vote or by
approval of the proxy statement of the Company in which such person is named as
a nominee for director without objection to such nomination) shall be, for
purposes of this Agreement, considered as though such person were a member of
the Incumbent Board; or

                     (iii)  upon approval by the Company's stockholders of a
reorganization, merger, share exchange or consolidation, other than one with
respect to which those persons who were the beneficial owners, immediately prior
to such reorganization, merger, share exchange or consolidation, or outstanding
securities of the Company ordinarily having the right to vote in the election of
directors own, immediately after such transaction, more than 75% of the
outstanding securities of the resulting corporation ordinarily having the right
to vote in the election of directors; or

                     (iv)   upon approval by the Company's stockholders of a
complete liquidation and dissolution of the Company or the sale or other
disposition of all or substantially all of the assets of the Company other than
to a Subsidiary.

       Notwithstanding the occurrence of any of the foregoing, the Board may
determine, if it deems it to be in the best interest of the Company and
consistent with a good faith interpretation of this Agreement, that an event or
events otherwise constituting a Change in Control shall not be so considered.
Such determination shall only be effective (A) if it is made by the Board prior
to the occurrence of an event that otherwise would be or probably will lead to a
Change in Control or after such event if made by the Board a majority of which
is composed of directors who were


                                      5
<PAGE>   6
members of the Board immediately prior to the event that otherwise would be or
probably will lead to a Change in Control and 75% or more of such directors vote
in favor of such determination, and (B) if it is made with respect to all
executive officers of the Company.  Upon such determination, such event or
events shall not be deemed to be in Change in Control for any purposes
hereunder.

       6.     Nondisclosure, Confidentiality; Competition.

              (a)    Employee agrees that, during the term of this Agreement and
of Employee's employment by the Company, and for a period twelve (12) months
after the termination of Employee's employment with the Company, Employee will
not in any manner, directly or indirectly, by himself or in conjunction with any
other person, (i) conduct any of the activities or perform any of the
responsibilities or duties that Employee provided the Company during his
employment by the Company for any business entity that is competitive with the
business of the Company or its affiliates or (ii) establish or own any
financial, beneficial or other interest in (other than an interest consisting of
less than one percent (1%) of a class of publicly traded security), make any
loan to or for the benefit of, or render any managerial, marketing or other
business advice, to any entity that is then conducting activities that are
competitive with those of the business of the Company or its affiliates, in
either case with a geographic territory defined as the greater of (i) a
seventy-five (75) miles radius of any renal dialysis center, unit or facility
owned or operated by the Company or an affiliate of the Company (an "RCG
Center"), or (ii) the geographic area, as narrowly construed as is practicable,
from which the Company received patients at each of the RCG Centers.  For
purposes of this Section, the "business of the Company or its affiliates" shall
mean owning or operating a renal dialysis center, unit or facility, and
providing practice management services to nephrologists.

       (b)    Employee further agrees that, for a period of three (3) years

reasonable care to be divulged to anyone, or use or otherwise appropriate for
Employee's own benefit or for the benefit of others, any knowledge or
information of a confidential nature with respect to the Company's and its
affiliates' current business, the Company itself, or any of its affiliates,
including all trade secrets, pricing information, marketing information or 
technical information (hereinafter referred to as the "Confidential Data"),
except for (i) a disclosure that is required by law; or (ii) information that
has been made generally available to the public by the act of one who has the
right to disclose such information; or (iii) information that has become part
of the public domain through no fault of the Employee; and (iv) was known to
the Employee prior to June 1995.  Employee hereby acknowledges and agrees that
the prohibitions against disclosure of Confidential Data recited herein are in
addition to, and not in lieu of, any rights or remedies which the Company may
have available pursuant to the laws of any jurisdiction or at common law to
prevent the disclosure of confidential information, and the enforcement by the
Company of its rights and remedies pursuant hereto shall not be construed as a
waiver of any other rights or available remedies which the Company may possess
in law or equity.  Employee acknowledges that the Company has



                                       6


<PAGE>   7
taken reasonable and appropriate steps to ensure the confidentiality and
non-disclosure of all such Confidential Data. For purposes of this Section the
Company's and its affiliates' "current business" shall mean owning or opening a
renal dialysis center, unit or facility.

       (c)    Employee further agrees that, for a period of three (3) years 
after the termination of Employee's employment with the Company, Employee will
not, for his own benefit or the benefit of others, solicit any person or entity
that has or has had, or disrupt or attempt to disrupt, any relationship,
contractual or otherwise, with the Company or an affiliate of the Company
(including any patient, payor, physician, provider, managed care organization
or supplier) or any time during Employee's employment with the Company, for the
purpose of assisting, or creating such a relationship for, any business entity
that is competitive with the Company or an affiliate of the Company.  For
purposes of this Section, a business entity is competitive with the Company or
an affiliate of the Company if it provides or offers any renal dialysis service
that is provided by the Company or an affiliate of the Company.

       (d)    Employee further agrees that, for a period of three (3) years
after the termination of Employee's employment with the Company, Employee shall
not induce, nor attempt to induce, any employee of the Company, or any of its
affiliates, to terminate such employee's association with the Company or any of
its affiliates.

       (e)    These post-employment covenants are considered by the parties
hereto to be fair, reasonable and integral for the protection of the Company.
The parties mutually agree that if a violation of any of these covenants occurs,
such violation or any threatened violation will cause irreparable injury to the
Company and the remedy at law for any such violation will cause irreparable
injury to the Company and the remedy at law for any such violation or threatened
violation will be inadequate.  The parties acknowledge that these covenants will
survive, and remain in effect and enforceable after, termination of this
Agreement.

       (f)    Employee agrees to indemnify and hold harmless the Company from
and against any and all claims, causes of action, damages and/or any other
losses suffered or incurred by the Company as a result of any breach or
purported breach by Employee of any agreement applicable to Employee which
existed prior to the time of the entering into of this Agreement.  Such
obligations of Employee to indemnify and hold the Company harmless shall include
any and all costs of defense of any such claim or threatened claim, including
reasonable attorneys' fees.

       7.     Severability.

              The parties hereto hereby expressly agree and contract that it is
not the intention of either party to violate any public policy, or any statutory
or common law, and that if any paragraph, sentence, clause or combination of 
the same of this Agreement shall be in violation of the laws of any state where
applicable, such paragraph, sentence, clause or the combination of the same 
shall be void in the jurisdictions where it is unlawful, and the remainder
thereof shall remain binding on the parties hereto.  It is the intention of the
parties to make the covenants of




                                       7
<PAGE>   8

this Agreement binding only to the extent that they may be lawfully done under
existing applicable laws.  In the event that any part of any term or covenant
of this Agreement is determined by a court of law or equity to be overly broad
or otherwise unenforceable, the parties hereto agree that such court shall be
empowered to substitute, and it is the intent of the parties hereto that such
court substitute, a reasonably judicially enforceable term or limitation in the
place of such unenforceable term or covenant, and that as so modified this
Agreement shall be fully enforceable.

        8.      Entire Agreement; Modification.

                This Agreement constitutes the entire agreement between the
parties and supersedes any and all prior understandings or agreements, and any
changes or additions hereto must be in writing and signed by both parties.

        9.      Assignment.

                (a)     The rights and benefits of Employee under this
Agreement, other than accrued and unpaid amounts due under Section 3(a) hereof,
are personal to Employee and shall not be assignable.

                (b)     This Agreement may not be assigned by the Company
except to an affiliate of the Company, provided that such affiliate assumes the
Company's obligations under this Agreement; provided, further, that if the
Company shall merge or effect a consolidation or share exchange with or into,
or sell or otherwise transfer substantially all its assets to, another business
entity, the Company may assign its rights hereunder to that business entity
without the consent of the Employee provided that it causes such business
entity to assume the Company's obligations under this Agreement.

        10.     Notice.

                The references to the notice periods of certain "days"
contained in this Agreement shall mean calendar days.  Any notice provided for
in this Agreement shall be delivered to Employee at the most recent address of
employee listed in the Company's then current employment records.  Notice to
the Company shall be delivered to the following address: c/o Renal Care Group,
Inc., 2100 West End Avenue, Suite 800, Nashville, Tennessee 37203, Attention:
President.

        11.     Waiver.

        The waiver by any party to this Agreement of a breach of any of the
provisions contained herein shall not operate or be construed as a waiver of
any subsequent breach.

        12.     Disputes and Governing Law.

        The Company and employee agree that any dispute arising in connection
with, or relating to, this Agreement or the termination of this Agreement, to
the maximum extent allowed by applicable law, shall be subject to resolution
through informal methods and, failing such efforts, through arbitration. 
Either party may notify the other party of the existence of a dispute by
written notice to the address indicated above in Section 10.  The parties shall
thereafter attempt in good faith to resolve their differences within thirty 
(30) days after the receipt of such notice.  If the dispute cannot be resolved
within such 30-day period, either party may file a written demand for
arbitration with the other party.  The arbitration shall proceed in accordance
with the terms of the Federal Arbitration Act and the rules and procedures of
the American Arbitration Association.  A single arbitrator shall be appointed
through the American Arbitration Association's procedures to resolve the 
dispute.

        The parties agree that in the event arbitration is necessary, the laws
of the State of Tennessee and any applicable federal law shall apply.  The
place of the arbitration shall be Nashville, Tennessee.   

        The award of the arbitrator shall be binding and conclusive upon the
parties.  Either party shall have the right to have the award made the
judgement of a court of competent jurisdiction in the State of Tennessee.

        In the event of a dispute arising under this Agreement, the prevailing
party shall be entitled to all reasonable attorneys' fees incurred in
connection with such dispute.  The Company agrees, to the maximum extent
permitted by law and the By-laws of the Company, to defend and indemnify the
Employee against and to hold the Employee harmless from any and all claims,
suits, losses, liabilities, and expenses (including disputes arising under this
Agreement and including reasonable attorney's fees and payment of reasonable
expenses incurred in defending against such claim or suite as such expenses are
incurred) asserted against the Employee for actions taken or omitted to be
taken by the Employee in good faith and within the scope of his
responsibilities as an officer or employee of the Company.  If requested by the
Employee, the Company shall advance to the Employee, promptly following the
Company's receipt of any such request, any and all expenses for which
indemnification is available hereunder.

flexibility to the Company in its ability to motivate, attract, and retain the
services of employees and consultants upon whose judgment, interest, and special
effort the successful conduct of the Company's operation is largely dependent.
Accordingly, the Plan permits the grant of stock option awards from time to time
to selected officers and key employees and consultants.

                                 STOCK OPTIONS
 
     7.1. GENERAL.  The Committee is authorized to grant Options to Participants
on the following terms and conditions:
 
          (a) Exercise Price.  The exercise price per share of Stock under an
     Option shall be determined by the Committee. The Committee may elect to
     grant Non-Qualified Stock Options with an exercise price per share of Stock
     less than the Fair Market Value of a share of Stock on the date any such
     Non-Qualified Stock Option is granted.
 
          (b) Time and Conditions of Exercise.
 
             (i) The Committee shall determine the time or times at which an
        Option may be exercised in whole or in part. The Committee also shall
        determine the performance or other conditions, if any, that must be
        satisfied before all or part of an Option may be exercised.
 
             (ii) In connection with the grant of any Options, the Committee may
        provide in the Option Agreement for the termination of all or any
        portion of the Options under certain circumstances, including, without
        limitation, termination of a Participant's employment, provided that the
        Committee may distinguish among various causes of termination as the
        Committee deems appropriate. In
 
                                        4
<PAGE>   5
 
        addition, the Committee may provide, through the Option Agreement or
        otherwise, that if a Participant's employment is terminated: (i) such
        Participant's Option(s) may be exercised for specified periods
        thereafter but no later than the expiration date of such Option; (ii) to
        the extent not fully exercisable on the date of termination of
        employment, such Option may continue to become exercisable within the
        term of the Option; or (iii) some or all of the Options not fully
        exercisable on the date of termination of employment may be deemed fully
        exercisable. A Participant's employment shall be deemed to terminate on
        the last date for which he or she receives a regular wage or salary
        payment (excluding severance payments unless otherwise provided in the
        Option Agreement). Whether military, government or other service or
        other leave of absence shall constitute a termination of employment
        shall be determined in each case by the Committee at its discretion, and
        any determination by the Committee shall be final and conclusive. A
        termination of employment shall not occur where the Participant
        transfers from the Company to one of its Subsidiaries, transfers from a
        Subsidiary to the Company or transfers from one Subsidiary to another
        Subsidiary.
 
          (c) Payment.  The Committee shall determine the methods by which the
     exercise price of an Option may be paid, the form of payment, including,
     without limitation, cash, shares of Stock, or other property (including
     "cashless exercise" arrangements), and the methods by which shares of Stock
     shall be delivered or deemed to be delivered to Participants. Without
     limiting the power and discretion conferred on the Committee pursuant to
     the preceding sentence, the Committee may, in the exercise of its
     discretion, but need not, allow a Participant to pay the exercise price of
     an Option by directing the Company to withhold from the shares of Stock
     that would otherwise be issued upon exercise of the Option that number of
     shares having a Fair Market Value on the exercise date equal to the
     exercise price, all as determined pursuant to rules and procedures
     established by the Committee.
 
          (d) Evidence of Grant.  All Options shall be evidenced by a written
     Option Agreement between the Company and the Participant. The Option
     Agreement shall include such provisions as may be specified by the
     Committee.
 
     7.2. INCENTIVE STOCK OPTIONS.  The terms of any Incentive Stock Options
granted under the Plan must comply with the following additional rules:
 
          (a) Exercise Price.  The exercise price per share of Stock shall be
     set by the Committee, provided that the exercise price for any Incentive
     Stock Option shall not be less than the Fair Market Value as of the date of
     the grant.
 
          (b) Exercise.  In no event may any Incentive Stock Option be
     exercisable for more than ten years from the date of its grant.
 
          (c) Individual Dollar Limitation.  The aggregate Fair Market Value
     (determined as of the time an Option is made) of all shares of Stock with
     respect to which Incentive Stock Options are first exercisable by a
     Participant in any calendar year may not exceed $100,000.
 
          (d) Ten Percent Owners.  No Incentive Stock Option shall be granted to
     any individual who, at the date of grant, owns stock possessing more than
     ten percent of the total combined voting power of all classes of stock of
     the Company or any Subsidiary unless the exercise price per share of such
     Option is at least 110% of the Fair Market Value per share of Stock at the
     date of grant and the Option expires no later than five years after the
     date of grant.
 
          (e) Expiration of Incentive Stock Options.  No award of an Incentive
     Stock Option may be made pursuant to the Plan on or after the tenth
     anniversary of the Effective Date.
 
          (f) Right To Exercise.  During a Participant's lifetime, an Incentive
     Stock Option may be exercised only by the Participant.
 
          (g) Interpretation of Incentive Stock Options.  In interpreting this
     Section 7.2 of the Plan and the provisions of individual Option Agreements
     granting Incentive Stock Options, the Committee shall be
 
                                        5
<PAGE>   6
 
     governed by the principles and requirements of Sections 421, 422 and 424 of
     the Code, and applicable Treasury Regulations.
 
                                   ARTICLE 8
 
                    GENERAL PROVISIONS APPLICABLE TO OPTIONS
 
     8.1. STAND-ALONE, TANDEM, AND SUBSTITUTE OPTIONS.  Options granted under
the Plan may, in the discretion of the Committee, be granted either alone or in
addition to, in tandem with, or in substitution for, any other Option granted
under the Plan. If an Option is granted in substitution for another Option, the
Committee may require the surrender of such other Option in consideration of the
grant of the new Option. Options granted in addition to or in tandem with other
Options may be granted either at the same time as or at a different time from
the grant of such other Options.
 
     8.2. EXCHANGE PROVISIONS.  The Committee may at any time offer to exchange
or buy out any previously granted Option for a payment in cash, Stock, or
another Option (subject to Section 8.1), based on the terms and conditions the
Committee determines and communicates to the Participant at the time the offer
is made.
 
     8.3. TERM OF OPTION.  The term of each Option shall be for the period as
determined by the Committee, provided that in no event shall the term of any
Incentive Stock Option exceed a period of ten years from the date of grant.
 
     8.4. LIMITS ON TRANSFER.  No right or interest of a Participant in any
Option may be pledged, encumbered, or hypothecated to or in favor of any party
other than the Company or a Subsidiary, or shall be subject to any lien,
obligation, or liability of such Participant to any other party other than the
Company or a Subsidiary. No Option shall be assignable or transferable by a
Participant other than by will or the laws of descent and distribution or,
except in the case of an Incentive Stock Option, pursuant to a domestic
relations order as defined in Section 414(p)(1)(B) of the Code, if the order
satisfies Section 414(p)(1)(A) of the Code.
 
     8.5. STOCK CERTIFICATES.  All Stock certificates delivered under the Plan
are subject to any stop-transfer orders and other restrictions as the Committee
deems necessary or advisable to comply with federal or state securities laws,
rules and regulations and the rules of any national securities exchange or
automated quotation system on which the Stock is listed, quoted, or traded. The
Committee may place legends on any Stock certificate to reference restrictions
applicable to the Stock.
 
     8.6. CHANGES IN CONTROL.
 
          (a) Change in Control Followed by Employment Termination.  In the
     event that a Change in Control shall occur and an employee Participant's
     employment shall terminate, except as provided in the next sentence, within
     twelve (12) months after the Change in Control, then (i) all unexercised
     Options (whether vested or not vested) shall automatically become one
     hundred percent (100%) vested immediately, (ii) no other terms, conditions,
     restrictions or limitations shall be imposed upon any such Options after
     such date, and in no circumstance shall an Option be forfeited on or after
     such date, and (iii) all such Options shall be valued on the basis of the
     greater of the Change in Control Price or the Fair Market Value on the date
     of such termination, and such value shall promptly be paid to the
     Participant in cash by the Company or its successor. The foregoing shall
     not apply if employment termination is due to (i) death, (ii) disability
     entitling the Participant to benefits under the Company's or its
     successor's long-term disability plan, (iii) Cause, or (iv) resignation
     (other than (A) resignation from a declined reassignment to a job that is
     not reasonably equivalent in responsibility or compensation or that is not
     in the same geographic area, or (B) resignation within 30 days following a
     reduction in base pay).
 
          (b) Automatic Acceleration and Cash-Out.  Upon a Change in Control
     that results directly or indirectly in the Stock (or the stock of any
     successor to the Company received in exchange for Stock) ceasing to be
     publicly traded in a national securities market, (i) all unexercised
     Options (whether vested or not vested) shall automatically become one
     hundred percent (100%) vested immediately, (ii) no other
 
                                        6
<PAGE>   7
 
     terms, conditions, restrictions or limitations shall be imposed upon any
     such Options after such date, and in no circumstance shall an Option be
     forfeited on or after such date, and (iii) all such Options shall be valued
     on the basis of the Change in Control Price, and such value shall promptly
     be paid to the Participant in cash by the Company or its successor.
 
          (c) Miscellaneous.  Upon a Change in Control, no action, including,
     without limitation, the amendment, suspension or termination of the Plan,
     shall be taken that would adversely affect the rights of any Participant or
     the operation of the Plan with respect to any Option to which a Participant
     may have become entitled hereunder on or prior to the date of the Change in
     Control or to which such Participant may become entitled as a result of
     such Change in Control.
 
     8.7. MODIFICATION, EXTENSION AND RENEWAL.  The Committee may modify, renew
or accept the surrender of outstanding Options issued under the Plan (or the
surrender of similar grants issued under any other plan of the Company or a
Subsidiary), including the acceleration or waiver of any vesting or other
restrictions or limitations, or the conversion of such Options (with appropriate
adjustments) to be applicable to the securities of any successor corporation to
the Company, and the Committee may authorize new Options pursuant to the Plan in
substitution for any outstanding Options. Any substituted, modified or converted
Options may bear such different or additional terms and conditions as the
Committee shall deem appropriate within the limitations of the Plan. The
determination of the Committee as to the terms of any of the foregoing may be
made without regard to whether a Change in Control has or has not occurred (or
whether the Committee has determined that any event shall not be considered to
be a Change in Control) and shall be conclusive and binding notwithstanding the
provisions of the respective agreements regarding exercisability. Any fractional
shares resulting from any of the foregoing adjustments under this Section shall
be disregarded and eliminated. However, no modification of an Option shall,
without the consent of the Participant holding the Option, adversely affect the
rights or obligations of such Participant with respect to such Option.
 
                                   ARTICLE 9
 
                          CHANGES IN CAPITAL STRUCTURE
 
     9.1. GENERAL.  If the Company's outstanding shares of Stock are increased
or decreased or changed into or exchanged for a different number or kind of
shares or other securities of the Company by reason of any recapitalization,
reclassification, stock split, combination of shares, stock dividend, or
transaction having similar effect, the Board shall proportionately and
appropriately adjust (i) the number of shares of Stock authorized and reserved
for grants under the Plan as set forth in Section 5.1, (ii) the number of shares
of Stock that may be subject to one or more Options granted to any one
Participant in any one taxable year as set forth in Section 5.4, and (iii) the
number and kind of shares that are subject to each Option and the exercise price
per share, without any change in the aggregate price to be paid therefor upon
exercise of each Option.
 
                                   ARTICLE 10
 
                    AMENDMENT, MODIFICATION AND TERMINATION
 
     10.1. AMENDMENT, MODIFICATION AND TERMINATION.  With the approval of the
Board, at any time and from time to time, the Committee may terminate, amend or
modify the Plan without stockholder approval; provided, however, that the
Committee may condition any amendment on the approval of stockholders of the
Company if such approval is necessary or deemed advisable with respect to tax,
securities or other applicable laws, policies or regulations.
 
     10.2 OPTIONS PREVIOUSLY GRANTED.  No termination, amendment, or
modification of the Plan shall adversely affect any Option previously granted
under the Plan, without the written consent of the Participant.

                                   ARTICLE 11
 
                               GENERAL PROVISIONS
 
     11.1. NO RIGHTS TO OPTIONS.  No Participant or employee shall have any
claim to be granted any Option under the Plan, and neither the Company nor the
Committee is obligated to treat Participants and employees uniformly.
 
     11.2. NO STOCKHOLDER RIGHTS.  No Option gives the Participant any of the
rights of a stockholder of the Company unless and until shares of Stock are in
fact issued to such person in connection with such Option.
 
     11.3. WITHHOLDING.  The Company or any Subsidiary shall have the authority
and the right to deduct or withhold, or require a Participant to remit to the
Company, an amount sufficient to satisfy federal, state, and local taxes
(including the Participant's FICA obligation) required by law to be withheld
with respect to any taxable event arising as a result of the Plan. With respect
to withholding required upon any taxable event under the Plan, the Committee
may, at the time the Option is granted or thereafter, require that any such
withholding requirement be satisfied, in whole or in part, by withholding shares
of Stock having a Fair Market Value on the date of withholding equal to the
amount to be withheld for tax purposes, all in accordance with such procedures
as the Committee establishes.
 
     11.4. NO RIGHT TO EMPLOYMENT.  Nothing in the Plan or any Option Agreement
shall interfere with or limit in any way the right of the Company or any
Subsidiary to terminate any Participant's employment at any time, nor confer
upon any Participant any right to continue in the employ of the Company or any
Subsidiary.
 
     11.5. UNFUNDED STATUS.  The Plan is intended to be an "unfunded" plan for
incentive and deferred compensation. With respect to any payments not yet made
to a Participant pursuant to the Plan, nothing contained in the Plan or any
Option Agreement shall give the Participant any rights that are greater than
those of a general creditor of the Company or any Subsidiary.
 
     11.6. RELATIONSHIP TO OTHER BENEFITS.  No payment under the Plan shall be
taken into account in determining any benefits under any pension, retirement,
savings, profit sharing, group insurance, welfare or benefit plan of the Company
or any Subsidiary.
 
     11.7. EXPENSES.  The expenses of administering the Plan shall be borne by
the Company and its Subsidiaries.
 
     11.8. TITLES AND HEADINGS.  The titles and headings of the Sections in the
Plan are for convenience of reference only, and in the event of any conflict,
the text of the Plan, rather than such titles or headings, shall control.
 
     11.9. GENDER AND NUMBER.  Except where otherwise indicated by the context,
any masculine term used herein also shall include the feminine; the plural shall
include the singular and the singular shall include the plural.
 
     11.10. FRACTIONAL SHARES.  No fractional shares of Stock shall be issued
and the Committee shall determine, in its discretion, whether cash shall be
given in lieu of fractional shares or whether such fractional shares shall be
eliminated by rounding up.
 
     11.11. SECURITIES LAW COMPLIANCE.  It is intended that the provisions of
the Plan and any grant of Options hereunder shall comply in all respects with
the terms and conditions of Rule 16b-3 under the Exchange Act, or any successor
provisions, as it relates to persons subject to the reporting requirements of
Section 16(a) of the Exchange Act. Any agreement granting any Options shall
contain such provisions as are necessary or appropriate to assure such
compliance. To the extent that any provision hereof is found not to be in
compliance with such Rule as it relates to such Act, such provision shall be
deemed to be modified so as to be in compliance with such Rule, or if such
modification is not possible, shall be deemed to be null and void, as it relates
to such Participant.

<PAGE>   9
 
     11.12. GOVERNMENT AND OTHER REGULATIONS.  The obligation of the Company to
make payment of awards in Stock or otherwise shall be subject to all applicable
laws, rules, and regulations, and to such approvals by government agencies as
may be required. The Company shall be under no obligation to register under the
Securities Act any of the shares of Stock paid under the Plan. If the shares
paid under the Plan may in certain circumstances be exempt from registration
under the Securities Act, the Company may restrict the transfer of such shares
in such manner as it deems advisable to ensure the availability of any such
exemption.
 
     11.13. GOVERNING LAW.  To the extent not governed by federal law, the Plan
and all Option Agreements shall be construed in accordance with and governed by
the laws of the State of Delaware.
 
     IN WITNESS WHEREOF, Renal Care Group, Inc., acting by and through its duly
authorized officers, has executed this instrument as of the      day of
            , 1996.

                            AMENDMENT NO. 1 TO THE
              RENAL CARE GROUP, INC. EMPLOYEE STOCK PURCHASE PLAN
 
 
        The Renal Care Group, Inc. Employee Stock Purchase Plan (the "Plan") be
and hereby is amended as follows:
 
        1.      Section 1.1 of the Plan is hereby deleted in its entirety and 
the following is hereby inserted in lieu thereof:
 
        1.1.    "Anniversary Date" shall mean January 1 of each year. 
 
        2.      Section 1.14 of the Plan is hereby deleted in its entirety and 
the following is hereby inserted in lieu thereof:
 
        1.14.   "Normal Monthly Pay" for purposes of determining the amount of 
a Participant's contributions for any Plan Year shall be (i) for hourly paid
Employees an amount computed by annualizing the Participant's hourly base pay
and his regular scheduled hours of work as of December 1 of the preceding Plan
Year and dividing by twelve (12), and (ii) for salaried employees, their
regular monthly base pay as of December 1 of the preceding Plan Year. For
purposes of computing a Participant's "Normal Monthly Pay" for contributions
during the first Plan Year, a Participant's hourly base pay and regular
scheduled hours of regular monthly base pay as applicable shall be determined
as of the later of (i) February 6, 1996, or (ii) his date of employment.
 
        3.      Section 1.19 of the Plan is hereby deleted in its entirety and 
the following is hereby inserted in lieu thereof:
 
        1.19.   "Plan Year" shall mean a twelve (12) month period beginning on 
the first day of January and ending on the last day of December of each year;
provided, however, that in the year of adoption, Plan Year shall mean the
period commencing on the Effective Date and ending on the last day of December,
1996.
 
        4.      Section 3.1 of the Plan is hereby deleted in its entirety and 
the following is hereby inserted in lieu thereof:
 
        3.1.    Every Employee who becomes an Employee during the first Plan 
Year (i.e., the Plan Year beginning on the Effective Date) and whose customary
employment is at least twenty (20) hours per week and more than five (5) months
in a calendar year shall be eligible to participate as of the date he or she
first becomes an Employee. Every other Employee whose customary employment is
at least twenty (20) hours per week and more than five (5) months in a calendar
year shall be eligible to participate as of any Anniversary 

<PAGE>   2

Date coincident with or immediately following his completion of at least six
(6) months of Continuous Service. An Employee shall not be eligible to
participate, however, if immediately after the Options are granted such
Employee would own stock possessing five percent (5%) or more of the total
combined voting power or value of all classes of the Sponsoring Employer or a
subsidiary corporation or parent corporation (as those terms are defined in
Section 424(e) and (f) of the Code). For purposes of this paragraph, the
ownership attribution rules of Section 424(d) of the Code shall apply in
determining the stock ownership of an Employee and stock which the Employee may
purchase under outstanding options (under this or any other plan or agreement)
shall be treated as stock owned by the Employee.
 
        5.      Section 4.2 of the Plan is hereby deleted in its entirety and 
the following is hereby inserted in lieu thereof:
 
        4.2.    With respect to the first Plan Year only, in addition to or in 
lieu of payroll contributions, a Participant may make cash contributions to his
or her Contribution Account, which, together with any payroll contributions
during the first Plan Year, do not exceed the product of (i) 10% of the
Participant's Normal Monthly Pay, and (ii) the number of partial or full months
in the first Plan Year (i.e., eleven). An election to make a cash contribution
shall be in writing on such form as provided by the Committee, and must be
received by the Employer no later than December 31, 1996. For all purposes of
this Plan, a Participant's cash contributions shall be allocated to and deemed
a part of the Participant's Contribution Account. No interest shall accrue or
be paid on any cash contributions under the Plan.
 
        6.      Section 5.2 of the Plan is hereby deleted in its entirety and 
the following is hereby inserted in lieu thereof:
 
        5.2.    The Issue Price of the Sponsoring Employer Stock under this Plan
shall be equal to the lesser of: (i) eighty-five percent (85%) of the Market
Price on the Exercise Date of each Plan Year; or (ii) eighty-five percent (85%)
of the Market Price on the Grant Date of each Plan Year. The Issue Price is
subject, however, to a "Minimum Issue Price" for each Plan Year. The "Minimum
Issue Price" for any Plan Year shall be the book value of the Sponsoring
Employer Stock as of the December 31 for the calendar year preceding the
calendar year during which the Grant Date for the Plan Year occurs.
Notwithstanding any provision to the contrary, if the Issue Price for any Plan
Year is less than the Minimum Issue Price, the Options granted for that Plan
Year shall be considered null and void and the payroll deductions credited to
the Participant's Contribution Account shall be returned to the Participant.

                               STATUS OF PARTIES

       5.1  INDEPENDENT CONTRACTOR STATUS.  It is mutually understood and agreed
that the PHYSICIAN is an independent contractor in his performance of the
professional services, duties and obligations contemplated by this Agreement.
The COMPANY shall neither have nor exercise any control or direction over the
methods or manner by which the PHYSICIAN performs his professional services and
functions.  Except for requiring the coverage of services called for in the
Agreement, the COMPANY shall not set nor shall it have the right to set, the
specific working hours of the PHYSICIAN.  The PHYSICIAN shall not be subject to
any policies or procedures applicable to the COMPANY except those required of
the COMPANY for it to be in compliance with governmental laws and regulations;
nor shall he be entitled to employee benefits including vacation pay, sick
leave, retirement benefits, Social Security, Workers' Compensation, disability
or unemployment insurance benefits that may be provided to the COMPANY's
employees.  The terms of this Agreement shall take precedence over any
inconsistent terms which may be found in the policies, PHYSICIAN applications,
or otherwise of the COMPANY as presently existing or as amended.

       5.2  PAYMENT OF TAXES.  The PHYSICIAN acknowledges that he will have sole
responsibility for the payment of all federal, state and local estimated,
withholding and employment taxes arising out of its relationship with and the
performance of the professional services for the COMPANY.  The PHYSICIAN
acknowledges and agrees that the COMPANY will not withhold on his behalf any
sums for income tax, unemployment insurance, social security or any other
withholding pursuant to any law or requirement of any governmental body, nor
will the COMPANY make available to the PHYSICIAN any of the benefits afforded to
employees of the COMPANY.  Each and every one of such payments, withholding and
benefits, if any, is the sole responsibility of the PHYSICIAN.  The PHYSICIAN
agrees to indemnify and hold the COMPANY harmless from any and all loss or
liability arising with respect to such payments, withholdings and benefits, if
any.  In the event the United States Internal Revenue Service ("IRS") should
question or challenge the


                                      4
<PAGE>   6
worker status of the PHYSICIAN, the parties hereto mutually agree that both the
PHYSICIAN and the COMPANY shall have the right to participate in any discussion
or negotiation occurring with the IRS, irrespective of or by whom such
discussions or negotiations are initiated; and, each party shall notify the
other in advance of any planned meeting or discussion.

     5.3 NO AGENCY.  The PHYSICIAN shall not have the right or authority and
hereby expressly covenants not to enter into a contract in the name of the
COMPANY or otherwise bind the COMPANY, in any way, without the express written
consent of the COMPANY. The PHYSICIAN shall hold the COMPANY harmless from any
loss attributable to a violation of this covenant.  However, PHYSICIAN shall
advise and assist the COMPANY in securing and retaining contracts in the name
and for the account of the COMPANY with such individuals or entities necessary
for the proper and efficient functioning of the COMPANY.

     5.4  ACCESS TO RECORDS.  If it is ultimately determined that Section 952
of the Omnibus Reconciliation Act of 1980 applies to this Agreement, the
PHYSICIAN will make available to the Secretary of the United States Department
of Health and Human Services, the United States Comptroller General, and their
representatives, this Agreement and all books, documents and records necessary
to certify the nature and extent of the costs of those services.  If the
PHYSICIAN carries out the duties of this Agreement through a subcontract worth
$10,000 or more over a twelve-month period with a related organization, the
subcontract will also contain an access clause to permit access by the
Secretary, Comptroller General, and their representatives to the related
organizations's books, documents and records.

of One Million Dollars ($1,000,000) per claim and Three Million Dollars
($3,000,000) in the aggregate per year, (the "Minimum Coverage").

     6.2  CONTINUING COVERAGE.  If the PHYSICIAN either changes insurance
carriers for any reason or switches from "claims made" to "occurrence"
coverage, or has the Minimum Coverage terminated for any reason, then the
PHYSICIAN shall obtain the requisite Minimum Coverage with prior acts coverage
containing a retroactive date sufficient to cover any claims arising out of
acts which occurred from the Effective Date of this Agreement through and
including the expiration date of the current coverage.

     6.3  EVIDENCE OF COVERAGE.  On execution of this Agreement and annually
thereafter or on reasonable request, the PHYSICIAN shall provide the COMPANY
with a certificate of insurance or other written instrument acceptable to the
COMPANY evidencing purchase of the requisite Minimum Coverage.  The PHYSICIAN
shall notify the COMPANY at least thirty (30) days prior

            (q) Cooperate with the COMPANY's insurance carriers and/or its

            (a) Patient long-term care plans, patient short-term care plans and
medical histories;

            (b) Results of physical examinations and laboratory tests; and

requesting to attend to patients at the Facility and forward a recommendation
concerning such applications to the COMPANY's Medical Advisory Board. The GROUP
shall maintain oversight of all disciplinary actions with regard to any matter
of such physicians or patient care personnel as needed to assure the quality of
services and conformity to COMPANY and Facility rules and policies.

        1.6 COVERAGE. The GROUP shall make available one or more physicians, at
a minimum, to provide services at each site for their respective hours of
operation. Should the Facility's patient case load increase, the COMPANY may
increase the GROUP's on-site obligation coverage accordingly and the GROUP shall
provide such coverage.

compensation for all services, covenants and agreements pursuant to this
Agreement; provided however, ninety (90) days prior to each annual anniversary
of the Effective Date of the Initial Term and any Renewal Term, the parties
shall discuss in good faith whether any adjustment to the compensation described

provided hereunder by the GROUP and the medical director services required by
the Facility for each year of this Agreement and to reflect any changes in
reimbursement levels for services provided by the Facilities or the economics of
owning and operating the facilities in each case with a view to determining the
fair market value of the services provided herein. No change to the compensation

employees of the COMPANY. The GROUP agrees to indemnify and

<PAGE>   8

respect to such payments, withholdings and benefits, if any. In the event the
United States Internal Revenue Service ("IRS") should question or challenge the
worker status of the GROUP or its physicians, the parties hereto mutually agree
that both the GROUP and the COMPANY shall have the right to participate in any
discussion or negotiation occurring with the IRS, irrespective of or by whom
such discussions or negotiations are initiated; and, each party shall notify

of its responsibilities as set forth in Section 1.2, the GROUP shall not have
the right or authority and hereby expressly covenants not to enter into a
contract in the name of the COMPANY or otherwise bind the COMPANY, in any way,
without the express written consent of the COMPANY. The GROUP shall hold the
COMPANY harmless from any loss attributable to a violation of this covenant.
However, GROUP shall advise and assist the COMPANY in securing and retaining
contracts in the name and for the account of the COMPANY with such individuals
or entities necessary for the proper and efficient functioning of the
Facilities.

        4.3 ACCESS TO RECORDS. If it is ultimately determined that ss. 952 of
the Omnibus Reconciliation Act of 1980 applies to this Agreement, then until the
expiration of four (4) years after the furnishing of services provided under
this Agreement, the GROUP will make available to the Secretary of the United
States Department of Health and Human Services, the United States Comptroller
General, and their representatives, this Agreement and all books, documents and
records necessary to certify the nature and extent of the costs of those
services. If the GROUP carries out the duties of this Agreement through a
subcontract worth $10,000 or more over a twelve-month period with a related
organization, the subcontract will also contain an access clause to permit
access by the Secretary, Comptroller General, and their representatives to the
related organization's books, documents and records.

                                   ARTICLE V
                                   INSURANCE

        5.1 MINIMUM INSURANCE COVERAGE. The GROUP shall purchase and maintain at
its expense for itself and each of the physicians professional and general

Three Million Dollars ($3,000,000) in the aggregate per year, (the "Minimum
Coverage") or such greater amount required by a governmental entity.

        5.2 CONTINUING COVERAGE. In the event that the GROUP switches from its
present "occurrence" coverage to "claims made" coverage and then if the GROUP
thereafter either changes insurance carriers for any reason or switches from
"claims made" to "occurrence" coverage, or has the Minimum Coverage terminated
for any reason, then the GROUP shall obtain the requisite Minimum Coverage with
prior acts coverage containing a retroactive date sufficient to cover any claims
arising out of acts which occurred from the Effective Date of this Agreement
through and including the expiration date of the current coverage.

        5.3 EVIDENCE OF COVERAGE. On execution of this Agreement and annually
thereafter or on reasonable request, the GROUP shall provide the COMPANY with
certificates of insurance or other written instruments acceptable to the COMPANY
evidencing purchase of the requisite Minimum Coverage for itself and each of the
GROUP's physicians. The GROUP shall notify the COMPANY at least sixty (60) days
prior to the voluntary cancellation or termination of any Minimum Coverages and
immediately upon receipt of any notice of involuntary cancellation or
termination of any Minimum Coverages.

                         AND NONSOLICITATION COVENANT

            (a) The GROUP agrees that, during the term of this Agreement and
for a period of three (3) years after the termination of this Agreement, the
GROUP will not in any manner, directly or indirectly, by itself or in
conjunction with any other person, (i) conduct any of the activities or perform

COMPANY, in either case within a seventy-five (75) mile radius of the Facility.
For purposes of this Article, the "business of the COMPANY" shall mean owning
or operating a renal dialysis center, unit or facility or providing renal
dialysis supplies or services to any other center, unit or facility or any
acute care facility or any home renal dialysis patient, including the provision
of pharmaceuticals or laboratory services.

        The terms and provisions of this Article VII shall also apply to each
physician of the GROUP or other physician performing services on behalf of the
GROUP hereunder (as may be approved by the COMPANY), any member or shareholder
of any professional corporation or association of which a GROUP is a shareholder
or any person with whom the GROUP is associated in partnership and in or with
respect to which by virtue of said professional corporation or partnership the
GROUP receives an indirect financial benefit. With respect to the persons
identified in this paragraph, the time periods applicable to this Article VII
shall begin on the earlier of (i) the termination or expiration of this
Agreement or (ii) a physician's departure from the GROUP or a physician
cessation of services hereunder on behalf of the GROUP.

            (b) The GROUP further agrees that during the term of this Agreement
and for a period of three (3) years after the termination of this Agreement,
the GROUP will keep confidential and not directly divulge, or allow through
reasonable care to be divulged to anyone, or use or otherwise appropriate for
the GROUP's own benefit or for the benefit of others, any knowledge or
information of a confidential nature with respect to the business of the
COMPANY, COMPANY itself, or any of its affiliates, including all trade secrets,
pricing information, marketing information or technical information
(hereinafter referred to as the "Confidential Data"), except for (i) a
disclosure that is required by law; or (ii) information that has been made
generally available to the public by the act of one who has the right to
disclose such information. The GROUP hereby acknowledges and agrees that the
prohibitions against disclosure of Confidential Data recited herein are in
addition to, and not in lieu of, any rights or remedies which the COMPANY may
have available pursuant to 



                                     - 8 -
<PAGE>   11

the laws of any jurisdiction or at common law to prevent the disclosure of
confidential information, and the enforcement by the COMPANY of its rights and
remedies pursuant hereto shall not be construed as a waiver of any other rights
or available remedies which the COMPANY may possess in law or equity. The GROUP
acknowledges that the COMPANY has taken reasonable and appropriate steps to
ensure the confidentiality and non-disclosure of all such Confidential Data.

            (c) The GROUP also agrees that during the term of this Agreement
and for a period of three (3) years after the termination of this Agreement,
the GROUP will not, for its own benefit or the benefit of others, solicit any
person or entity that has or has had, or disrupt or attempt to disrupt, any
relationship, contractual or otherwise, with the COMPANY (including any
patient, payor, physician, provider, managed care organization or supplier) at

or any of its affiliates, to terminate his or her association with the COMPANY
or any of its affiliates.

            (e) These covenants are considered by the parties hereto to be
fair, reasonable and integral for the protection of the COMPANY. The parties
mutually agree that if a violation of any of these covenants occurs, such
violation or any threatened violation will cause irreparable injury to the
COMPANY and the remedy at law for any such violation or threatened violation
will be inadequate. The parties acknowledge that these covenants will survive,
and remain in effect and enforceable after, termination of this Agreement.

            (f) Nothing in these covenants shall be deemed to prohibit the
physicians of the GROUP from exercising their medical judgment concerning the
medical treatment of a patient in any manner whatsoever in any location
whatsoever, and shall not be deemed to require the referral of any such patient
to any facility of the COMPANY or any of its affiliates. The GROUP acknowledges
that enforcement of this covenant will not prevent a physician of the GROUP
from earning a living by practicing medicine or nephrology.

            (g) The GROUP hereby further agrees that prior to the engagement of
any physician as an independent contractor or the employment of a physician to
perform services for the patients or medical practice of the GROUP, the GROUP
will require as a condition of said physician's engagement or employment that
the physician enter into a supplemental non-compete agreement with the COMPANY
like the one contained within. It is expressly understood and agreed by the
GROUP that its promises in this subparagraph (g) have served as a material
inducement to the COMPANY to enter into this Agreement.

                              EMPLOYMENT AGREEMENT


       THIS AGREEMENT is made and entered into as of June 30, 1996, by and
between RENAL CARE GROUP, INC., a Delaware corporation (the "Company"), and GARY
BRUKARDT (hereinafter "Employee").



                                  WITNESSETH:

       WHEREAS, the Company desires to employ Employee, and Employee desires to
be employed by the Company, on the terms and conditions contained herein; and

       WHEREAS, in serving as an employee of the Company, Employee has and will
participate in the use and development of confidential proprietary information
about the Company, its customers and suppliers, and the methods used by the
Company and its employees in competition with other companies, as to which the
Company desires to protect fully its rights; and

       WHEREAS, the Company wishes to enter into an agreement with Employee
whereby Employee shall agree not to compete with the Company in any current or
future business activity conducted or entered into by the Company and to hold
certain information obtained by and through Employee's employment in confidence.

       NOW, THEREFORE, in consideration of the compensation payable to
Employee by the Company pursuant to this Agreement, and the mutual promises,
covenants, representations and warranties contained herein, the receipt and

provided herein (the "Base Compensation"), payable according to the pay periods
of the Company as may be in effect from time to time.  Such payments shall be
prorated for periods less than a full pay period.  The Base Compensation
shall be subject to withholding for federal, state and local payroll and all
other taxes or withholdings applicable to Employee.  Any increase of the Base
Compensation shall be at the discretion of the Company, provided that any
decreases to the then current Base Compensation shall require the consent of
Employee.

          (b)  Benefits:  During the term of this Agreement, Employee shall

at least four (4) weeks of paid vacation time.  In addition, Employee shall be
entitled to those other benefits described on the exhibit attached hereto and
incorporated herein by reference.

          (c)  Bonuses:  In addition to the Base Compensation payable to

incorporated herein by reference.

              (d)  Expenses:  The Company shall reimburse Employee for any and
all expenses reasonably incurred by employee incident to the performance of the
duties imposed upon Employee hereunder.

       4.  Duties, Extent of Services:

           Employee is engaged as Executive Vice President and Chief Operating
Officer and shall perform such duties and responsibilities as are typically
incident thereto, and shall perform in a faithful and competent manner such
additional duties as may be reasonably assigned from time to time by the
Company.  Such duties shall be performed on a full-time basis for the Company
at the Company's offices in Nashville, Tennessee.  Employee may be required,
from time to time, to perform his duties temporarily hereunder at such other
place or places as the Company shall reasonably require, provided that such
period does not exceed thirty (30) consecutive days without Employee's consent
and that during any such period Employee is able to return to Nashville,
Tennessee at the Company's expense for weekends.

       Employee shall devote all of Employee's business time, attention,
knowledge, and skill solely to the business and interest of the Company, and the
Company shall be entitled to all the benefits, profits, and other issues arising
from, or incident to, all work, services, and advice of Employee.

     5.  Termination.

         This Agreement may be terminated by the parties in the manners 
specified below: 

         (a)  Termination without Cause.  Either the Company or the employee
may terminate Employee's employment under this Agreement at any time for any
reason upon thirty (30) day's prior written notice to the other party.

         (b)  Termination for Cause.

              The Company may terminate this Agreement on written notice at any
time for "cause".  For purposes of this Agreement, "cause" shall mean: (i)
Employee is convicted of, pleads guilty to, or confesses to a felony or any
crime involving any act of dishonesty, fraud, misappropriation, embezzlement or
moral turpitude, in which event the Company may terminate this Agreement
immediately, (ii) the gross misconduct or gross negligence by Employee in
connection with the performance of Employee's duties hereunder, (iii) the
engaging by Employee in any fraudulent, disloyal or unprofessional conduct
which results in a material injury to the Company, its affiliates or any of its
or their centers, monetarily or otherwise, (iv) Employee breaches any provision
of Section 6 of this Agreement, or (v) the failure by Employee to otherwise
substantially perform his duties with the Company (other than any such failure
resulting from the disability of Employee under Section 5(c)(i)) or the breach
of any provision of this Agreement other than Section 6.  In the event of any
termination for cause pursuant to the provisions of (ii), (iii), (iv) or (v) of
this subsection, the Company shall give Employee written notice prior to such
termination detailing the specific acts, actions, failures, or events upon
which the forecast termination is based, and Employee shall have fifteen (15)
days after such written notice to cease such actions or otherwise correct any
such failure or breach.  If Employee does not cease such action or otherwise
correct such failure or breach within such fifteen day time period, or having
once received such written notice and ceased such actions or corrected such
failure or breach, Employee at any time thereafter again so acts, fails or
breaches, the Company may terminate this Agreement immediately.

         (c)  Involuntary Termination.

              The employment of Employee hereunder shall be automatically
terminated by the death or disability of Employee as outlined below.

              (i)  Disability.  The Company may terminate this Agreement at the
time Employee shall have been Disabled for a continuous period of six (6)
months during any continuous twelve month period.  For purposes of this
Paragraph 5(c)(i), the term "Disabled" shall mean Employee's inability to
perform the essential functions of his duties, with or without reasonable
accommodation.  During Employee's six month period of Disability or such longer

                                      3
<PAGE>   4
wait period as may be provided for in any policy of disability that may be
maintained by the Company for the benefit of Employee, the Company agrees to
continue to pay Employee's Base Compensation (less regular withholdings for
payroll or other taxes and other required or proper items, and less any
payments from all disability plans provided by the Company).  In the event of
a termination of Employee on account of Disability, however, the Company shall
be obligated to pay only Employee's Base Compensation that has been earned
through the effective date of termination (less regular withholdings for
payroll or other taxes and other required or proper times, and less any
payments from all disability plans provided by the Company).

        (ii)    Death.  In the event Employee shall die during the term of this
Agreement, this Agreement shall terminate and Employee's estate shall receive
the remainder of the Base Compensation set forth in Section 3(a) hereof accrued
to the last day of the month in which death occurs.

    (d) Post-Termination Compensation.  Except as provided in Section 5(c)
above, upon termination of this Agreement, the Company shall be relieved of all
of its obligations hereunder notwithstanding any period of time remaining under
the initial or any renewal term, subject to the following:

        (i)     Termination without Cause.  In the event that the Company
terminates Employee's employment hereunder without Cause under Section 5(a)
above, then Employee shall, after the effective date of such termination, as
Employee's sole and exclusive remedy, receive the Base Compensation (as then in
effect) for a period of twelve (12) months after the termination date.  If the
Employee's employment is terminated by the Company without Cause, the Employee
shall be under no duty to seek or accept other employment; but if he shall do
so, any compensation he shall receive therefrom shall not diminish the
Company's obligation to make payments required to the Employee hereunder.  In
the event that Employee terminates his or her employment under Section 5(a)
above, the Company's obligation to pay Employee's Base Compensation shall
terminate as of the date of termination.

        (ii)    Termination for Cause.  In the event that the Company
terminates Employee's employment hereunder with Cause under Section 5(b) above,
then Employee shall, after the effective date of such termination, as
Employee's sole and exclusive remedy, receive the Base Compensation (as then in
effect) for a period of one (1) month after the termination date.

        (iii)   Termination following Change in Control.  If within twelve (12)
months following a Change in Control (as defined below), either (A) the Company
terminates the employment of Employee hereunder without Cause under Section
5(a) above or (B) Employee resigns from a declined reassignment of a job that
is not reasonably equivalent in responsibility or compensation that is not in
the same geographic area, then, in lieu of any other compensation that may be
specified herein, Employee shall continue to receive the Base Compensation (as
then in effect) for a period of thirty-six (36) months from the date of
termination payable in the same manner as it was being paid as of the date of
termination, provided, however, that the salary payment provided for hereunder
may at the option of the


                                      4




<PAGE>   5
Company be paid in a single lump-sum payment, to be paid not later than thirty
(30) days after termination.  In the event such obligation arises, no
compensation received from other employment (or otherwise) shall reduce the
obligation to make the payment(s) described in this paragraph.

       (e)    Change in Control.  "Change in Control" means a change in control
of the Company of a nature that would be required to be reported (assuming such
event has not been "previously reported") in response to Item 1(a) of a Current
Report on Form 8-K pursuant to Section 13 of 15(d) of the Exchange Act of 1934
(the "Exchange Act"); provided that, without limitation, a Change in Control
shall also be deemed to have occurred at such time as:

              (i)    any "person" within the meaning of Section 14(d) of the
Exchange Act, other than the Company; a subsidiary, or any employee benefit
plan(s) sponsored by the Company or any Subsidiary, is or has become the
"beneficial owner," as defined in rule 13d-3 under the Exchange Act, directly or
indirectly, of 25% or more of the combined voting power of the outstanding
securities of the Company ordinarily having the right to vote at the election of
directors, or

              (ii)   individuals who constitute the Board immediately prior to
any meeting of stockholders (the "Incumbent Board") have ceased for any reason
to constitute at least a majority thereof, provided that any person becoming a
director whose election, or nomination for election by the Company's
stockholders, was approved by a vote of a least three-quarters (3/4 )of the
directors comprising the Incumbent Board (either by a specific vote or by
approval of the proxy statement of the Company in which such person is named as
a nominee for director without objection to such nomination shall be, for
purposes of this Agreement, considered as though such person were a member of
the Incumbent Board; or

              (iii)  upon approval by the Company's stockholders of a
reorganization, merger, share exchange or consolidation, other than one with
respect to which those persons who were the beneficial owners, immediately
prior to such reorganization, merger, share exchange or consolidation, or
outstanding securities of the Company ordinarily having the right to vote in the
election of directors own, immediately after such transaction, more than 75% of
the outstanding securities of the resulting corporation ordinarily having the
right to vote in the election of directors; or

              (iv)   upon approval by the Company's stockholders of a complete
liquidation and dissolution of the Company or the sale or other disposition of
all or substantially all of the assets of the Company other than to a
Subsidiary.

       Notwithstanding the occurrence of any of the foregoing, the Board may
determine, if it deems it to be in the best interest of the Company and
consistent with a good faith interpretation of this Agreement, that an event
otherwise constituting a Change in Control shall not be so considered.  Such
determination shall only be effective (A) if it is made by the Board prior to


                                       5

<PAGE>   6

the occurrence of an event that otherwise would be or probably will lead to a
Change in Control or after such event if made by the Board a majority of which
is composed of directors who were members of the Board immediately prior to the
event that otherwise would be or probably will lead to a Change in Control and
75% or more of such directors vote in favor of such determination, and (B) if it
is made with respect to all executive officers of the Company.  Upon such
determination, such event or events shall not be deemed to be a Change in
Control for any purposes hereunder.

       6.     Nondisclosure, Confidentiality; Competition.

              (a)    Employee agrees that, during the term of this Agreement and
of Employee's employment by the Company, and for a period twelve (12) months
after the termination of Employee's employment with the Company, Employee will
not in any manner, directly or indirectly, by himself or in conjunction with any
other person, (i) conduct any of the activities or perform any of the
responsibilities or duties that Employee provided the Company during his
employment by the Company for any business entity that is competitive with the
business of the Company or its affiliates or (ii) establish or own any
financial, beneficial or other interest in (other than an interest consisting of
less than one percent (1%) of a class of publicly traded security), make any
loan to or for the benefit of, or render any managerial, marketing or other
business advice, to any entity that is then conducting activities that are
competitive with those of the business of the Company or its affiliates, in
either case within a geographic territory defined as the greater of (i) a
seventy-five (75) mile radius of any renal dialysis center, unit or facility
owned or operated by the Company or an affiliate of the Company (an "RCG
Center"), or (ii) the geographic area, as narrowly construed as is practicable,
from which the Company received patients at each of the RCG Centers.  For
purposes of this Section, the "business of the Company or its affiliates" shall
mean owning or operating a renal dialysis center, unit or facility, and
providing practice management services to nephrologists.

       (b)    Employee further agrees that, for a period of three (3) years
after the termination of Employee's employment with the Company, Employee will
keep confidential and not directly divulge, or allow through a lack of
reasonable care to be divulged to anyone, or use or otherwise appropriate for
Employee's own benefit or for the benefit of others, any knowledge or
information of a confidential nature with respect to the Company's and its
affiliates' current business, the Company itself, or any of its affiliates,
including all trade secrets, pricing information, marketing information or
technical information (hereinafter referred to as the "Confidential Data"),
except for (i) a disclosure that is required by law; or (ii) information that
has been made generally available to the public by the act of one who has the
right to disclose such information; or (iii) information that has become part of
the public domain through no fault of the Employee; and (iv) was known to the
Employee prior to June 1996.  Employee hereby acknowledges and agrees that the
prohibitions against disclosure of Confidential Data recited herein are in
addition to, and not in lieu of, any rights or remedies which the Company may
have available pursuant to the laws of any jurisdiction or at common law to
prevent the disclosure of confidential information, and the enforcement by the
Company of its rights and remedies


                                       6

<PAGE>   7

pursuant hereto shall not be construed as a waiver of any other rights or
available remedies which the Company may possess in law or equity.  Employee
acknowledges that the Company has taken reasonable and appropriate steps to
ensure the confidentiality and non-disclosure of all such Confidential Data.
For purposes of this Section the Company's and its affiliates' "current 
business" shall mean owning or opening a renal dialysis center, unit or
facility.

       (c)    Employee further agrees that, for a period of three (3) years
after the termination of Employee's employment with the Company, Employee will
not, for his own benefit or the benefit of others, solicit any person or entity
that has or has had, or disrupt or attempt to disrupt, any relationship,
contractual or otherwise, with the Company or an affiliate of the Company
(including any patient, payor, physician, provider, managed care organization or
supplier) at any time during Employee's employment with the Company, for the
purpose of assisting, or creating such a relationship for, any business entity
that is competitive with the Company or an affiliate of the Company.  For
purposes of this Section, a business entity is competitive with the Company or
an affiliate of the Company if it provides or offers any renal dialysis service
that is provided by the Company or an affiliate of the Company.

       (d)    Employee further agrees that, for a period of three (3) years
after the termination of Employee's employment with the Company, Employee shall
not induce, nor attempt to induce, any employee of the Company, or any of its
affiliates, to terminate such employee's association with the Company or any of
its affiliates.

       (e)    These post-employment covenants are considered by the parties
hereto to be fair, reasonable and integral for the protection of the Company.
The parties mutually agree that if a violation of any of these covenants occurs,
such violation or any threatened violation will cause irreparable injury to the
Company and the remedy at law for any such violation or threatened violation
will be inadequate.  The parties acknowledge that these covenants will survive,
and remain in effect and enforceable after, termination of this Agreement.

       (f)    Employee agrees to indemnify and hold harmless the Company from
and against any and all claims, causes of action, damages and/or any other
losses suffered or incurred by the Company as a result of any breach or
purported breach by Employee of any agreement applicable to Employee which
existed prior to the time of the entering into of this Agreement.  Such
obligations of Employee to indemnify and hold the Company harmless shall include
any and all costs of defense of any such claim or threatened claim, including
reasonable attorneys' fees.

       7.     Severability.

              The parties hereto hereby expressly agree and contract that it is
not the intention of either party to violate any public policy, or any statutory
or common law, and that if any paragraph, sentence, clause or combination of the
same of this Agreement shall be in violation of the laws of any state where
applicable, such paragraph, sentence, clause or the combination of


                                       7


<PAGE>   8
the same shall be void in the jurisdictions where it is unlawful, and
the remainder thereof shall remain binding on the parties hereto.  It is the 
intention of the parties to make the covenants of this Agreement binding only
to the extent that they may be lawfully done under existing applicable laws. 
In the event that any part of any term or covenant of this Agreement is
determined by a court of law or equity to be overly broad or otherwise
unenforceable, the parties hereto agree that such court shall be empowered to
substitute, and it is the intent of the parties hereto that such court
substitute, a reasonably judicially enforceable term or limitation in the place
of such unenforceable term or covenant, and that as so modified this Agreement
shall be fully enforceable.

       8.     Entire Agreement; Modification.

              This Agreement constitutes the entire agreement between the
parties and supersedes any and all prior understandings or agreements, and any
changes or additions hereto must be in writing and signed by both parties.

       9.     Assignment.

              (a)    The rights and benefits of Employee under this Agreement,
other than accrued and unpaid amounts due under Section 3(a) hereof, are
personal to Employee and shall not be assignable.

              (b)    This Agreement may not be assigned by the Company except to
an affiliate of the Company, provided that such affiliate assumes the Company's
obligations under this Agreement; provided, further, that if the Company shall
merge or effect a consolidation or share exchange with or into, or sell or
otherwise transfer substantially all its assets to, another business entity, the
Company may assign its rights hereunder to that business entity without the
consent of the Employee provided that it causes such business entity to assume
the Company's obligations under this Agreement.

       10.    Notice.

              The references to the notice periods of certain "days" contained
in this Agreement shall mean calendar days.  Any notice provided for in this
Agreement shall be delivered to Employee at the most recent address of employee
listed in the Company's then current employment records.  Notice to the Company
shall be delivered to the following address: c/o Renal Care Group, Inc., 2100
West End Avenue, Suite 800, Nashville, Tennessee 37203, Attention: President.

       11.    Waiver.

       The waiver by any party to this Agreement of a breach of any of the
provisions contained herein shall not operate or be construed as a waiver of any
subsequent breach.

<PAGE>   9
       12.    Disputes and Governing Law.

       The Company and employee agree that any dispute arising in connection
with, or relating to, this Agreement or the termination of this Agreement, to
the maximum extent allowed by applicable law, shall be subject to resolution
through informal methods and, failing such efforts, through arbitration.
Either party  may notify the other party of the existence of a dispute by
written notice to the address indicated above in Section 10.  The parties shall
thereafter attempt in good faith to resolve their differences within thirty
(30) days after the receipt of such notice.  If the dispute cannot be resolved
within such 30-day period, then the parties will submit the dispute for
mediation.  If mediation efforts are not successful, then either party may file
a written demand for arbitration with the other party.  The arbitration shall
proceed in accordance with the terms of the Federal Arbitration Act and the
rules and procedures of the American Arbitration Association.  A single
arbitrator shall be appointed through the American Arbitration Association's
procedures to resolve the dispute.

       The parties agree that in the event arbitration is necessary, the laws of
the State of Tennessee and any applicable federal law shall apply.  The place of
the arbitration shall be Nashville, Tennessee.

       The award of the arbitrator shall be binding and conclusive upon the
parties.  Either party shall have the right to have the award made the judgment
of a court of competent jurisdiction in the State of Tennessee.

       In the event of a dispute arising under this Agreement, the prevailing
party shall be entitled to all reasonable attorney's fees incurred in connection
with such dispute.  The Company agrees, to the maximum extent permitted by law
and the By-laws of the Company, to defend and indemnify the Employee against and
to hold the Employee harmless from any and all claims, suits, losses,
liabilities, and expenses (including disputes arising under this Agreement and
including reasonable attorneys' fees and payment of reasonable expenses incurred
in defending against such claim or suite as such expenses are incurred) asserted
against the Employee for actions taken or omitted to be taken by the Employee in
good faith and within the scope of his responsibilities as an officer or
employee of the Company.  If requested by the Employee, the Company shall
advance to the Employee, promptly following the Company's receipt of any such
request, any and all expenses for which indemnification is available hereunder.

                               DIALYSIS PROGRAM
                             MANAGEMENT AGREEMENT


THIS AGREEMENT is made effective this 1st day of March, 1996 ("Effective Date")
by and between The Cleveland Clinic Foundation, an Ohio non-profit corporation,
and Renal Care Group, Inc., a Tennessee corporation ("Management Company").

                                 WITNESSETH:

        WHEREAS, Management Company is engaged in the business of managing
dialysis units; and

        WHEREAS, The Cleveland Clinic Foundation desires that Management
Company manage its current outpatient dialysis services program ("UNIT")
pursuant to this Agreement; and

        WHEREAS, Management Company agrees to manage the UNIT under the name,
The Cleveland Clinic Foundation;

        NOW, THEREFORE, in consideration of the mutual covenants and
undertakings contained in this Agreement, The Cleveland Clinic Foundation and
Management Company agree as follows:

                         I.  AUTHORITY OF THE PARTIES

        1.1     Ultimate Control.  The Cleveland Clinic Foundation shall at all
times exercise ultimate authority and control over the policies and assets of

accordance with the intent of the parties, Management Company shall, subject to
the approval of The Cleveland Clinic Foundation, establish general
administrative policies which shall be carried out by Management Company as

<PAGE>   2

     1.3     Relationship of the Parties.  The parties hereto intend by this
Agreement solely to effect the appointment of Management Company for
administrative management of UNIT as described herein, and does not extend to
or involve any other activities of either The Cleveland Clinic Foundation or
Management Company, except as set forth in Section 1.4 herein.  No other
relationship is intended to be created between the parties hereto and nothing
in this Agreement shall be construed as to make either party hereto the
employer or employee of the other, agent or principal of the other, the joint
venturer or partner of the other, or have the right to, or control of, or in any
manner conduct the other's business; other than as is herein explicitly
provided.

     1.4     Exclusivity.  Without the prior consent of The Cleveland Clinic
Foundation, Management Company shall not provide outpatient dialysis management
services other than to The Cleveland Clinic Foundation during the term of this
Agreement within the area outlined on Exhibit A attached hereto and made a part
hereof; provided, however, that this shall not prohibit the Management Company
from providing such services to MetroHealth System (which shall include its
affiliated entities) in Cleveland, Ohio.

                           II. MANAGEMENT PERSONNEL

     2.1     Administrator.

          2.1.1     Management Company shall hire and appoint an administrator 
for the UNIT ("Administrator"), who shall be an employee of Management Company.
Notwithstanding the above, the appointment of the Administrator shall be
subject to the approval of The Cleveland Clinic Foundation.

          2.1.2     The Administrator shall have general day-to-day 
responsibility for the management of the UNIT, other than those duties 
specifically delegated to the Medical Director pursuant to this Agreement.


     2.2     Medical Director.

          2.2.1     The Cleveland Clinic Foundation, on the recommendation of

          2.2.2     The Medical Director shall supervise all professional

of utilization review, quality assurance, and related functions as directed by

as The Cleveland Clinic Foundation may deem appropriate, and which do not
interfere with the performance of the Medical Director's duties under this
agreement.  The Cleveland Clinic Foundation shall be responsible for the

<PAGE>   3


compensation, including fringe benefits, expenses, including professional
liability insurance, and other support and operating costs of the Medical
Director.
     2.3     Other Personnel.  The Cleveland Clinic Foundation and Management
Company each shall, at its sole expense, employ, pay, and supervise some other
personnel reasonably necessary to perform each party's duties under this
Agreement, and in such party's discretion may remove and/or reassign such other

however, that Management Company shall be reimbursed by The Cleveland Clinic
Foundation, as set forth in the Annual Operating Plan, approved by The
Cleveland Clinic pursuant to Section 3.2 hereon, for the cost of the Management
Company Health Care Personnel assigned to and performing services at the Unit.

     2.4     In the event either party reasonably determines that any personnel
provided by the other party should be terminated or re-assigned as a result of
lack of competence, conduct or behavior detrimental to patient care, the party
employing such individual shall promptly review such determination and make
reasonable best efforts to take appropriate personnel action, in accordance
with its customary personnel policies and procedures.

                         III. ADMINISTRATIVE SERVICES

     3.1     General Responsibilities and Services.  Management Company shall
perform those services as set forth in this Article III, and all related
functions as are reasonably necessary for the effective management of the
operations of the UNIT.  Management Company shall establish operational
policies for the UNIT, subject to The Cleveland Clinic Foundation's approval,
and shall implement those policies.  Management Company shall perform its

                6.2.3     The Cleveland Clinic Foundation shall defend or settle

the ownership of the Marks.

                        VII.  INSURANCE AND INDEMNIFICATION

        7.1     Each party (the"Indemnitor") shall indemnify, save and hold
harmless the other party (the "Indemnitee") from and against any and all
judgments, damages, costs and expenses, including reasonable attorney's fees,
paid or incurred by the Indemnitee in any claim, action or proceeding for damage
to property, injury or death to person, or otherwise, arising solely out of the
proven negligent acts or omissions of Indemnitor in Indemnitor's performance
under this Agreement.  Indemnitee obligations as set forth in the preceding
sentence are conditioned upon (i) Indemnitee promptly notifying Indemnitor of
any claim, demand or action, or any incident of which Indemnitee has actual and
constructive knowledge, which may reasonably result in a claim, demand or
action, and for which Imdemnite will look to Indemnitor for indemnification
under this Section, (ii) Indemnitee, its directors, officers, employees and
servants, shall reasonably and in good-faith cooperate with Indemnitor in
Indemnitor's investigation and review of any such claim, demand, action or
incident, and (iii) Indemnitee not entering into any admissions, agreements or
settlements which may affect the rights of Indemnitee or Indemnitor without the
prior written consent and approval of Indemnitor.  Indemnitor reserves the
right, in its sole discretion, to assume the defense of Indemnitee in any such
claim, action or proceeding.       

        7.2     The Indemnitee shall have the right to employ separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnitee unless (a)
employment of such counsel and payment of the fees and expenses thereof by the
Indemnitor has been specifically authorized by the Indemnitor, or (b) in the
reasonable judgment of such Indemnitee, employment of such counsel is necessary
because the claim or defense for which such counsel is employed is inconsistent
or in conflict with the claims or defenses of the Indemnitor, or (c) the
Indemnitee shall have reasonably concluded that there may be claims or defenses
available to it that are different from or in addition to those available to
the Indemnitor, in any of which events such fees and expenses shall be borne by
the Indemnitor, but in any such event, the Indemnitor shall not have the right
to direct the defense of such action on behalf of the Indemnitee.  The
Indemnitor shall not be liable for any settlement of any such action effected
without the Indemnitor's consent by the Indemnitee, but if settled with consent
of the Indemnitor or if there shall be a final judgment for the plaintiff in
such action against the Indemnitee or the Indemnitor with or without the
consent of Indemnitor, the Indemnitor agrees to indemnity and hold harmless the
Indemnitee to the extent provided herein.

        7.3     Each party shall procure and maintain for the term of this
Agreement professional liability insurance in a minimum amount of $3,000,000

a claims-made form following termination of this Agreement, coverage shall
survive for a period of no less than five (5) years.  Coverage shall provide
for a retroactive date of placement coinciding with the Effective Date of this
Agreement.  The Cleveland Clinic Foundation shall reimburse Management Company

on a full-time basis at the UNIT, provided such costs are set forth in the
Annual Operating Plan, approved by The Cleveland Clinic Foundation, pursuant to
Section 3.2 hereof.

        The Cleveland Clinic Foundation, at its expense, will provide
professional liability insurance coverage for the Medical Director of the UNIT
and for its other employees providing services to the UNIT hereunder.

compensation, termination and all matters relating to any persons, companies or
corporations employed by Management Company, for any reason whatsoever in
regard hereto, arising herefrom or otherwise, and shall indemnify and hold The
Cleveland Clinic Foundation harmless from any liability arising from the
employment by Management Company of any such persons or companies, including
any liability arising under the Civil Rights Act of 1964, as amended, the
Americans with Disabilities Act of 1990, the Age Discrimination in Employment
Act, and any other relevant federal, state, and local laws or regulations.

        7.6     No individual whose compensation for services is paid by
Management Company shall be in any way, directly or indirectly, expressly or by
implication, deemed an employee of The Cleveland Clinic Foundation or any
related entity, nor shall any such individual, be deemed to be employed by The

pleading admitting or failing to deny or to contest the material allegations of
the petition filed against it in any such proceeding; its seeking or consent
to, or acquiescence in the appointment of, any trustee, receiver, or liquidator
of it or any material part of its property; or the commencement against it of
any involuntary case under the Bankruptcy Code, or a proceeding under any
receivership, composition, readjustment, liquidation, insolvency, dissolution,
or like law or statute, which case or proceeding is not dismissed or vacated
within sixty (60) days from commencement.

                8.2.2     Termination for Breach or Default.  If either party

following the giving of the Notice of Default, the Defaulting Party in good
faith commences to cure the default, and thereafter diligently and continuously
pursues the curing to completion within thirty (30) days of such notice, unless
the default is impossible to cure within thirty (30) days, in which event the
defaulting party must continuously and diligently pursue a cure to completion
within a reasonable time, it shall be deemed that the Notice of Default has not
been given and the 

                                      10
<PAGE>   11
Defaulting Party shall not lose any of its rights under this Agreement by
reason thereof, although such Defaulting Party may be required to pay interest
relating to such default if so required by the terms of this Agreement.  If,
within the ten (10) day notice period, the Defaulting Party does not commence
in good faith the curing to the default or does not thereafter diligently and
continuously prosecute and achieve the curing to completion within the
applicable cure period, the Non-Defaulting Party shall have the right to
terminate this Agreement upon ten (10) days' written notice to the Defaulting
Party.

consultation with Management Company, The Cleveland Clinic Foundation shall have
the right to solicit all non-officer Management Company employees in the event
of a termination by Management Company hereunder.  Such assistance shall be
rendered in a manner consistent with usual and customary practice and The
Cleveland Clinic Foundation's needs.

unlicensed persons or relationships between management corporations and
physicians; or (b) any party to this Agreement has reasonable belief that such
findings may be made, then the Management Company and The Cleveland Clinic
Foundation shall use their best efforts to reform or reorganize the structure
of their relationship described in this Agreement so that such violation or
alleged violation no longer exists; provided, however, that notwithstanding
such efforts and reformation or reorganization, in the event of (a) above,
either party may elect to terminate this Agreement by proving sixty (60) days
prior written notice, and upon such termination, neither party shall have any
liability to the other party with respect to this Agreement except incurred
prior to termination or with respect to such violation or alleged violation to 
the extent that Hospital and Foundation restructure or reorganize their
relationship, they  shall do so to preserve to the greatest extent possible the
economic relationship between them.

        IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the date first above written.
