NOTE 1 - BASIS OF PRESENTATION

Overview

         Renal Care Group, Inc. (the "Company") 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"). As of June 30, 1998, the Company provided dialysis and ancillary
services to approximately 10,500 patients through 151 outpatient dialysis
centers in 18 states, and acute dialysis services in 87 hospitals.

         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 erythropoietin
("EPO"), a bio-engineered hormone used to treat anemia; (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 treatments per
year, with reimbursement for services provided primarily through the Medicare
ESRD program based on rates that are established by the Health Care Financing
Administration ("HCFA"). For the six months ended June 30, 1998, approximately
67% 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 private health insurance, effective September 1, 1997, the health insurance
coordination period was extended to 30 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 greater 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.

Interim Financial Statements

         In the opinion of management, the information contained herein reflects
all adjustments necessary to make the results of operations for the interim
periods a fair statement of such operations. All such adjustments are of a
normal recurring nature. Operating results for interim periods are not
necessarily indicative of results which may be expected for the year as a whole.
It is suggested that these financial statements be read in conjunction with the
consolidated financial statements and the related notes thereto included in the
Company's Form 10-K as filed with the Securities and Exchange Commission on
March 31, 1998.

NOTE 2 - SUBSEQUENT EVENTS

         On July 23, 1998, the Board of Directors approved a three-for-two stock
split to be effected in the form of a 50% stock dividend. One additional share
of Common Stock will be issued for every two shares held by shareholders of
record at the close of business on August 7, 1998. The additional shares will be
distributed on August 24, 1998. Financial data included in this filing has
not been retroactively adjusted for this stock split.

NOTE 4 - RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1997, the FASB issued Statement No. 131, "Disclosures about
Segments of an Enterprise and Related Information" ("Statement 131"). Statement
131 establishes standards for the way public business enterprises are to report
information about operating segments in annual financial statements and requires
those enterprises to report selected information about operating segments in
interim financial reports issued to shareholders. It also establishes standards
for related disclosures about products and services, geographic areas and major

Item 2.  MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS


RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 30, 1998 COMPARED TO THREE MONTHS ENDED JUNE 30, 1997

         Net revenue. Net revenue increased from $51,666,000 for the three
months ended June 30, 1997 to $89,510,000 for the three months ended June 30,
1998, an increase of $37,844,000, or 73.2%. This increase resulted primarily
from a 57.5% increase in the number of treatments from 249,139 in the 1997
period to 392,498 in the 1998 period. This growth in treatments is the result of
the acquisition and development of various dialysis facilities and a 10.1%
increase in same-center treatments for the 1998 period over the 1997 period. In
addition, average patient revenue per treatment increased 7.8% from $206 in the
1997 period to $222 in the 1998 period. The remaining revenue increase is a
result of wound care revenues from the December 1997 acquisition of STAT
Healthcare, higher management fees and earnings of 50% owned partnerships in the
1998 period compared to the 1997 period. The revenue per treatment increase is
due to an improvement in the Company's payor mix, increases in EPO and other
drug utilization, the implementation of the Company's in-house laboratory
services and the positive impact of commercial payments of the Medicare
secondary payor provisions of the Balanced Budget Act.

         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
$35,635,000 for the three months ended June 30, 1997 to $59,183,000 for the
three months ended June 30, 1998, an increase of $23,548,000, or 66.1%. This
increase resulted primarily from an increase in the number of treatments
performed during the period which caused a corresponding increase in the use of
labor, drugs and supplies. Patient care costs as a percent of net revenue
decreased from 69.0% in the 1997 period to 66.1% in the 1998 period primarily
due to an increase in net revenues. Patient care costs per treatment increased
from $143 in the 1997 period to $151 in the 1998 period, an increase of $8,
or 5.6%. This increase is due to EPO and other drug utilization costs, the cost
of providing in-house laboratory services and normal healthcare inflation.

         General and Administrative Expenses. General and administrative
expenses include corporate office costs and facility costs not directly related
to the care of patients, including facility administration, accounting, billing
and information systems. General and administrative expenses increased from
$5,206,000 for the three months ended June 30, 1997 to $8,579,000 for the three
months ended June 30, 1998, an increase of $3,373,000, or 64.8%. General and
administrative expenses as a percent of net revenue decreased from 10.1% in the
1997 period to 9.6% in the 1998 period, primarily due to an increase in net
revenue for the 1998 period.

         Provision for Doubtful Accounts. It is the Company's practice to
reserve for doubtful accounts in the period in which the revenue is recognized
based on management's estimate of the net collectibility of the accounts
receivable based upon an analysis of payor mix, billing practices and other
factors. The provision for doubtful accounts increased from $1,230,000 for the
three months ended June 30, 1997 to $2,319,000 for the three months ended June
30, 1998. The provision for doubtful accounts as a percent of net revenue
increased from 2.4% in the 1997 period to 2.6% in the 1998 period, or 0.2%. This
increase in provision for doubtful accounts was due to an increase in reserves
related to the amount of

            MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                     AND RESULTS OF OPERATIONS - (CONTINUED)

net operating revenues generated from non-governmental payor sources, and the
temporary degradation of accounts receivable collections associated with the
conversion of patient billing systems.

         Depreciation and Amortization. Depreciation and amortization increased
from $2,141,000 for the three months ended June 30, 1997 to $4,538,000 for the
three months ended June 30, 1998, an increase of $2,397,000, or 111.9%. This net
increase was due to the start-up of dialysis facilities, the normal replacement
costs of dialysis facilities and equipment, the purchase of information systems
and the amortization of the goodwill associated with the acquisitions accounted
for under the purchase method of accounting.

         Merger Expenses. Merger expenses of $300,000 represented legal,
accounting, employee severance and related benefits and other assimilation and
transitional costs related to the Company's merger with four dialysis facilities
located in Missouri, Kansas and Oklahoma.

         Income from Operations. Income from operations increased from
$7,154,000 for the three months ended June 30, 1997 to $14,591,000 for the three
months ended June 30, 1998, an increase of $7,437,000, or 103.9%. Income from
operations as a percent of net revenue increased from 13.8% in the 1997 period
to 16.3% in the 1998 period. Income from operations increased due to the
increase in net revenue in excess of patient care costs, which was primarily due
to an increase in the number of treatments performed during the period.

         Interest, Net. Interest income was $99,000 for the three months ended
June 30, 1997 and interest expense was $780,000 for the three months ended June
30, 1998. Interest expense is a result of borrowings from the Company's credit
facility. The use of the credit facility increased due to the use of cash in
acquisitions and de novo facilities, the replacement of dialysis facilities and
equipment and the purchase of information systems.

         Minority Interest. Minority interest represents the proportionate
equity interest of other partners in the Company's consolidated entities which
are not wholly-owned. As of June 30, 1998, this was primarily comprised of three
joint venture partnerships.

RESULTS OF OPERATIONS

SIX MONTHS ENDED JUNE 30, 1998 COMPARED TO SIX MONTHS ENDED JUNE 30, 1997

         Net revenue. Net revenue increased from $97,775,000 for the six months
ended June 30, 1997 to $169,973,000 for the six months ended June 30, 1998, an
increase of $72,198,000, or 73.8%. This increase resulted primarily from a 59.6%
increase in the number of treatments from 473,307 in the 1997 period to 755,403
in the 1998 period. This growth in treatments is the result of the acquisition
and development of various dialysis facilities and a 10.1% increase in
same-center treatments for the 1998 period over the 1997 period. In addition,
average patient revenue per treatment increased 6.8% from $205 in the 1997
period to $219 in the 1998 period. The remaining revenue increase is a result of
hyperbaric and wound care revenues as a result of the STAT acquisition, higher
management fees and earnings of 50% owned partnerships in the 1998 period
compared to the 1997 period. The revenue per

            MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                     AND RESULTS OF OPERATIONS - (CONTINUED)

treatment increase is due to an improvement in the Company's payor mix,
increases in EPO and other drug utilization, the implementation
of the Company's in-house laboratory services and the positive impact on
commercial payments of the Medicare Secondary Payor Provisions of the Balanced
Budget Act.

         Patient Care Costs. Patient care costs increased from $67,569,000 for
the six months ended June 30, 1997 to $112,723,000 for the six months ended June
30, 1998, an increase of $45,154,000, or 66.8%. This increase was due to the
increase in the number of associated treatments, which caused a corresponding
increase in the use of labor, drugs and supplies. Patient care costs as a
percent of net revenue decreased from 69.1% in the 1997 period to 66.3% in the
1998 period. Patient care costs per treatment increased from $143 in the 1997
period to $149 in the 1998 period, an increase of $6 or 4.2%. This increase is
due to greater EPO and other drug utilization costs, the cost of providing
in-house laboratory services and normal healthcare inflation.

         General and Administrative Expenses. General and administrative
expenses increased from $10,008,000 for the six months ended June 30, 1997 to
$16,428,000 for the six months ended June 30, 1998, an increase of $6,420,000,
or 64.1%. General and administrative expenses as a percent of net revenue
decreased from 10.2% for the 1997 period to 9.7% in the 1998 period, primarily
as a result of higher net revenues for the 1998 period.

         Provision for Doubtful Accounts. The provision for doubtful accounts
increased from $2,172,000 for the six months ended June 30, 1997 to $4,420,000
for the six months ended June 30, 1998, an increase of $2,248,000, or 103.5%.
The provision for doubtful accounts as a percent of net revenue increased from
2.2% for the six months ended June 30, 1997 to 2.6% for the six months ended
June 30, 1998, or 0.4%. The increase in the provision for doubtful accounts was
influenced by the amount of net operating revenues generated from
non-governmental payor sources and the temporary degradation of accounts
receivable collections due to the conversion of patient billing systems.

         Depreciation and Amortization. Depreciation and amortization increased
from $4,105,000 for the six months ended June 30, 1997 to $8,475,000 for the six
months ended June 30, 1998, an increase of $4,370,000, or 106.5%. This net
increase was due to the acquisition and start-up of dialysis facilities, the
normal replacement costs of dialysis facilities and equipment, the purchase of
information systems and the amortization of the goodwill associated with
the acquisitions accounted for under the purchase method of accounting.

         Merger Expenses. Merger expenses of $1,000,000 represented legal,
accounting, employee severance and related benefits and other assimilation and
transitional costs related to the Company's merger of the operations of thirteen
dialysis facilities located in Arkansas, Missouri, Kansas and Oklahoma.

         Income from Operations. Income from operations increased from
$13,621,000 for the six months ended June 30, 1997 to $26,927,000 for the six
months ended June 30, 1998, an increase of $13,306,000, or 97.7%. Income from
operations as a percent of net revenue increased from 13.9% in the 1997 period
to 15.8% in the 1998 period. Income from operations increased due to the
increase in net

revenue in excess of patient care costs, which was primarily due to an increase
in the number of treatments performed during the period.

         Interest, Net. Interest income was $503,000 for the six months ended
June 30, 1997 and interest expense was $1,342,000 for the six months ended June
30, 1998. Interest expense is a result of borrowings from the Company's credit
facility. The use of the credit facility increased due to the use of cash in
acquisitions and de novo facilities, the replacement of dialysis facilities and
equipment and the purchase of information systems.

         Minority Interest. Minority interest represents the proportionate
equity interest of other partners in the Company's consolidated entities which
are not wholly-owned. As of June 30, 1998, this was primarily comprised of three
joint venture partnerships.

LIQUIDITY AND CAPITAL RESOURCES

         The Company requires capital primarily for the acquisition and the
development of dialysis facilities, the purchase of property and equipment for
existing facilities and to finance working capital requirements. At June 30,
1998, the Company's working capital was $38,739,000, cash and cash equivalents
were $16,026,000 and the Company's current ratio was 1.7 to 1.

         The Company's net cash provided by operating activities was $9,104,000
for the six months ended June 30, 1998. Cash provided by operating activities
consists of net income before depreciation and amortization expense, partially
offset by increases in accounts receivable and other current assets. The
Company's net cash used in investing activities was $38,703,000 for the six
months ended June 30, 1998. Cash used in investing activities resulted primarily
from $32,238,000 of cash paid for acquisitions, net of cash acquired, and
$10,090,000 of capital expenditures, partially offset by a $3,625,000 decrease
in investments.

         Cash provided by financing activities was $36,487,000 for the six
months ended June 30, 1998. Cash provided by financing activities resulted
primarily from $35,385,000 in net borrowings under the line of credit in
connection with certain acquisitions and $4,069,000 in proceeds from the
exercise of stock options, offset by $2,717,000 in debt paid in connection with
merger transactions.

         A significant component of the Company's growth strategy is the
acquisition and development of dialysis facilities. The Company believes that
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 for the foreseeable future.
However, 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.

            MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                     AND RESULTS OF OPERATIONS - (CONTINUED)

         Capital expenditures of approximately $28,000,000, primarily for
equipment replacement, expansion of existing dialysis facilities and
construction of de novo facilities are planned in 1998. The Company has made
capital expenditures to date of $10,090,000. The Company expects that such
capital expenditures will be funded with cash provided by operating activities
and available lines of credit. The Company believes that capital resources
available to it will be sufficient to meet the needs of its business, both on a
short- and long-term basis.

RISK FACTORS

         In evaluating the Company and its business, prospective investors
should carefully consider the following risk factors in addition to the other
information contained herein. This quarterly report contains statements that
constitute "forward-looking" statements within the meaning of the Private
Securities Litigation Reform Act of 1995. Such forward-looking statements relate
to future events or the future financial performance of the Company and involve
known and unknown risks, uncertainties and other factors that may cause the
actual results, performance or achievements of the Company to be materially
different from any future results, performance or achievements expressed or
implied by such forward-looking statements. Such factors include, among other
things, those discussed below, and such factors could cause actual results to
differ materially from those indicated by such forward-looking statements. The
Company undertakes no obligation to publicly update or revise any
forward-looking statements, whether as a result of new information, future
events or otherwise. In light of these risks and uncertainties, there can be no
assurance that the forward-looking information contained in this quarterly
report or the materials incorporated herein by reference will in fact transpire.

         Limited Combined Operating History. The Company has conducted
operations as a combined entity only since February 1996, 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. 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 effect on the Company's results of
operations, financial condition or business.

         Dependence On Government Reimbursement. The Company estimates that
approximately 68%, 63% and 61% of its net revenue for the years ended December
31, 1996 and 1997, and the six months ended June 30, 1998, respectively,
consisted of reimbursements from Medicare under the ESRD program, including
revenue for the reimbursement of the administration of EPO. 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. 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




                                       11
<PAGE>   14

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.

         Revenues from the administration of EPO (the substantial majority of
which are reimbursed through Medicare and Medicaid programs) were approximately
19%, 21% and 23% of the net revenue of the Company for the years ended December
31, 1996 and 1997, and the six months ended June 30, 1998, respectively. EPO
reimbursement significantly affects the Company's earnings. The President has
included in his 1999 budget a proposal to decrease Medicare reimbursement for
EPO. Any reduction in reimbursement rates for EPO could have a material adverse
effect on the Company's results of operations, financial condition or 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
results of operations, financial condition or business.

         The Company estimates that approximately 6%, 7% and 6% of the Company's
net revenue for the years ended December 31, 1996 and 1997, and the six months
ended June 30, 1998, 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.

         Dependence On Other Sources Of Reimbursement. The Company estimates
that approximately 26%, 30% and 33% of its net revenue for the years ended
December 31, 1996 and 1997, and the six months ended June 30, 1998,
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 toward 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 or business.

         Risks Associated With Growth Strategy. The Company's strategy includes
expanding its dialysis business through the acquisition and development of
dialysis centers and the 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



                                       12
<PAGE>   15

dialysis center, some or all of which could have a material adverse effect on
the Company's results of operations, financial condition or 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 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.

         Risks Associated With Liabilities Of Acquired Businesses. The Company
has acquired and will continue to acquire businesses with prior operating
histories. Acquired companies may have unknown or contingent liabilities,
including liabilities for failure to comply with health care laws and
regulations, such as billing and reimbursement, fraud and abuse and similar
anti-referral laws. The Company has from time to time identified certain past
practices of acquired companies that do not conform to its standards. Although
the Company institutes policies designed to conform such practices to its
standards following completion of acquisitions, there can be no assurance that
the Company will not become liable for past activities that may later be
asserted to be improper by private plaintiffs or government agencies. Although
the Company generally seeks to obtain indemnification from prospective sellers
covering such matters, there can be no assurance that any such matter will be
covered by indemnification or, if covered, that the liability sustained will not
exceed contractual limits or the financial capacity of the indemnifying party.

         Dependence On Physician Referrals. The Company's dialysis centers
depend upon 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 conditions and business. 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 as the illegal remuneration provisions of the Social Security
Act and similar state laws which prohibit the payment of remuneration to induce
referrals, such physician owners may be forced to dispose of their stock in the
Company.

         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, false claims, health and safety,
environmental compliance and toxic waste disposal. Much of this regulation,
particularly in the areas of fraud and abuse and patient referral, is complex
and open to differing interpretations. First, the illegal remuneration
provisions of the Anti-Kickback Statute 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, the Stark Law
prohibits physician referrals for "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 exemptions, 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




                                       13
<PAGE>   16

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. Sanctions for violating these federal and state laws may include
civil monetary fines, disqualification from participation in the Medicare or
Medicaid programs and 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 could
result in a material adverse effect on the Company's results of operations,
financial condition or business.

         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, HIPAA, among other things,
provides for insurance portability for individuals who lose or change jobs,
limits exclusions for pre-existing conditions and establishes a pilot program
for medical savings accounts. HIPAA also amends existing crimes and criminal
penalties for Medicare fraud and enacts new federal health care fraud crimes. 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 statutes,
regulations, or programs may have on the Company's operations.

         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.

         Dependence On Key Personnel. The Company is dependent upon the services
of certain key executive officers. 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 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 or business.

                             RENAL CARE GROUP, INC.
                      NON-QUALIFIED STOCK OPTION AGREEMENT
                                FOR SAM A. BROOKS


         1. Exercise of Option. This Option may be exercised in whole or in
part, but in no less than one hundred (100) share lots, by written notice, in
substantially the form as Exhibit 1hereto, directed to the Secretary of the
Company at its principal place of business, accompanied by payment of the
Exercise Price for the number of shares purchased. Payment shall be made in
cash, by check, or in shares of Common Stock already held by the Optionee prior
to the exercise of the Option. In the event that all or part of the Exercise
Price is paid in shares of Common Stock, the value of such shares shall be equal
to the Fair Market Value of such shares on the date of exercise of the Option,
and the Optionee shall deliver to the Company a certificate or certificates for
such shares.

         2. Issuance of Option Shares. Upon a valid exercise of this Option, the
Company shall, or shall direct its transfer agent to, make delivery of the
Option Shares as soon as reasonably possible; provided, however, that the
Company shall not be required to issue or deliver any certificates for Option
Shares pursuant to this Option prior to (a) the completion of any registration
or qualification of such shares under any federal or state law, or any ruling or
regulation of any governmental body which the Board shall, in its sole
discretion, determine to be necessary or advisable, and/or (b) the Optionee
making at the time of exercise any reasonable representations and warranties
requested by the Company in order to qualify the issuance of the Option Shares
for exemptions from registration under state or federal securities laws. The
Option Shares issued on the exercise of this Option, when paid for as herein
provided, will be fully paid and non-assessable.

         3. Termination of Employment or Death.

                  (a) In the event of a termination of Optionee's employment or
consulting services for any reason (other than a termination of an Optionee
employee by his or her death or disability), (i) except as provided in clause
(ii) of this sentence this Option shall

terminate as of the day of notice of such termination by either party, but in no
event later than the Expiration Date, and (ii) any unexercised portion of this
Option which is otherwise exercisable on the date of termination may be
exercised by Optionee at any time within three (3) months following the date of
such termination, unless Optionee dies during such three (3) month period, but
in no event later than the Expiration Date. If Optionee is an employee, whether
military, government or other service by Optionee or other leave of absence
granted to Optionee shall constitute such a termination shall be determined in
each case by the Board at its discretion, and any determination by the Board
shall be final and conclusive. If the Board determines that such absence does
not constitute such a termination, however, Optionee may exercise his or her
option only with the consent of the Board.

                  (b) If Optionee is an employee, upon termination of Optionee's
employment with the Company (including its subsidiaries) as result of a
permanent disability (as defined by Section 22(e)(3) of the Code), (i) except as
provided in clause (ii) of this sentence, this Option shall terminate and be
unexercisable on the date of such termination, but in no event later than the
Expiration Date, and (ii) any unexercised portion of this Option which is
otherwise exercisable on the date of such termination may be exercised by
Optionee at any time within six (6) months following the date of such
termination, unless Optionee dies during such six (6) month period, but in no
event later than the Expiration Date.

                  (c) If Optionee is an employee, upon termination of his or her
employment by the Company without Cause, if there is a written employment
agreement between Optionee and the Company, this Option shall cease to vest in
accordance with the Vesting Schedule regardless of any salary continuation
specified by such employment agreement as a result of such termination. Upon
termination of his or her employment with the Company, (i) except as provided in
clause (ii) of this sentence, this Option shall terminate and be unexercisable
as to unvested options on the date of termination, but in no event later than
the Expiration Date, and (ii) any unexercised portion of this Option which is
otherwise exercisable as of such termination date may be exercised by Optionee
at any time within three (3) months following such termination date, unless
Optionee dies during such three (3) month period such option may be exercised
pursuant to subparagraph (d) below, but in no event later than the Expiration
Date. If there is no

                                                [OFFICERS/EMPLOYEES/CONSULTANTS]


written employment agreement between Optionee and the Company, upon termination
of his or her employment by the Company without Cause any unexercised portion of
this Option shall terminate in accordance with Section 3(a) above, but in no
event later than the Expiration Date.

                  (d) If Optionee dies, (i) except as provided in clause (ii) of
this sentence, this Option shall terminate and be unexercisable on the date of
death, and (ii) any unexercised portion of this Option, if otherwise exercisable
at the date of death, may be exercised by his or her personal representatives,
heirs, or legatees at any time prior to the expiration of one (1) year after the
date of Optionee's death, but in no event later than the Expiration Date.

         4. Full Information. Optionee represents that he or she is familiar
with the business and affairs of the Company and realizes that the receipt of
the Option and Option Shares is a speculative investment and that any possible
profit therefrom is uncertain. Optionee further represents that he or she has
had the opportunity to ask questions of and receive answers from the Company and
any person acting on its behalf and to obtain all information available with
respect to the Company and its affairs, and has received all information and
data with respect to the Company that he or she has requested and which he or
she has deemed relevant in connection with his or her receipt of the Option and
the Option Shares subject to the Option.

         5. No Rights in Option Stock. Optionee shall have no rights as a
stockholder with respect to any of the Option Shares prior to the date of
issuance to the Optionee of a certificate or certificates for such shares.
Optionee shall have no rights with respect to such shares not expressly
conferred by this Agreement.

         6. Stock Reserved. The Company shall at all times during the term of
this Agreement reserve and keep available such number of shares of the Common
Stock as will be sufficient to satisfy the requirements of this Agreement, and
shall pay all original issue taxes on the exercise of this Option, and all other
fees and expenses necessarily incurred by the Company in connection therewith.

         7. Nonassignability. This Option shall not be encumbered or transferred
in whole or in part except by will or the laws of descent and distribution and
is exercisable during the lifetime of the Optionee only by the Optionee.

         8. No Employment. This Agreement shall not give Optionee a right to
employment by, or membership on the board of directors of, the Company or its
subsidiaries.

         9. Non-Qualified Option. It is the intent of the parties hereto that
this Option be a non-qualified stock option and subject to all of the applicable
provisions of the Internal Revenue Code of 1986, as amended. The Company
recognizes that the Optionee may be subject to restrictions regarding his or her
right to trade Common Stock under applicable securities laws. Accordingly, the
Optionee may want to consider making an election to be taxed upon exercise of
this Option under Section 83(b) of the Code. The Optionee shall have sole
discretion to make such an election and shall be solely responsible for
complying with the Code and all relevant rules and regulations in connection
with such election. The Optionee shall provide written notice to the Company of
such election immediately after making such election.

         10. Share Adjustments. If the Company's outstanding shares of Common
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

         11. Changes in Control.

                  (a) Change in Control. Subject to Section 12, in the event
that a Change in Control shall occur, then (i) this Option (whether vested or
not vested) shall automatically become one hundred percent (100%) vested
immediately, and (ii) no other terms, conditions, restrictions or limitations
shall be imposed upon this Option after such

date, and in no circumstance shall this Option be forfeited on or after such
date.

                  (b) Automatic Acceleration and Cash-Out. Subject to Section
12, upon a Change in Control that results directly or indirectly in the Common
Stock (or the stock of any successor the Company received in exchange for Common
Stock) ceasing to be publicly traded on a national securities market at any
time, (i) this Option shall automatically become one hundred percent (100%)
vested immediately with respect to the Option Shares, (ii) no other terms,
conditions, restrictions or limitations shall be imposed upon this Option after
such date, and in no circumstance shall this Option be forfeited on or after
such date, and (iii) this Option shall be valued and cashed out on the basis of
the Change in Control Price.

                  (c) Section 16 Insider. Notwithstanding anything herein to the
contrary, if the Optionee is subject to the reporting requirements of Section 16
of the Exchange Act with respect to the Company, and on the date of the Change
in Control this Option has not been outstanding for a period of at least six
months from the Date of Grant, the Optionee shall not be paid the consideration
described in this Section 11 above until the first day next following the end of
such six-month period.

         12. Modification, Extension and Renewal. The Board may modify, renew or
accept the surrender of this Option, including the acceleration or waiver of any
vesting or other restrictions or limitations, or the conversion of this Option
(with appropriate adjustments) to be applicable to the securities of any
successor corporation to the Company or parent of any such successor, and the
Board may authorize new options in substitution for the Option. Any substituted,
modified or converted options may bear such different or additional terms and
conditions as the Board shall deem appropriate. The determination of the Board
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 Board has determined
that any event shall not be considered to be a Change in Control) and shall be
conclusive and binding notwithstanding the provisions hereof regarding
exercisability. Any fractional shares resulting from any of the foregoing
adjustments under this Section shall be disregarded and eliminated. However, no
modification of this Option shall, without the consent of

                         ADDITIONAL TERMS AND CONDITIONS
                             RENAL CARE GROUP, INC.
                      NON-QUALIFIED STOCK OPTION AGREEMENT
                              FOR GARY A. BRUKARDT


           1. Exercise of Option. This Option may be exercised in whole or in
  part, but in no less than one hundred (100) share lots, by written notice, in
  substantially the form as Exhibit 1hereto, directed to the Secretary of the
  Company at its principal place of business, accompanied by payment of the
  Exercise Price for the number of shares purchased. Payment shall be made in
  cash, by check, or in shares of Common Stock already held by the Optionee
  prior to the exercise of the Option. In the event that all or part of the
  Exercise Price is paid in shares of Common Stock, the value of such shares
  shall be equal to the Fair Market Value of such shares on the date of exercise
  of the Option, and the Optionee shall deliver to the Company a certificate or
  certificates for such shares.

           2. Issuance of Option Shares. Upon a valid exercise of this Option,
  the Company shall, or shall direct its transfer agent to, make delivery of the
  Option Shares as soon as reasonably possible; provided, however, that the
  Company shall not be required to issue or deliver any certificates for Option
  Shares pursuant to this Option prior to (a) the completion of any registration
  or qualification of such shares under any federal or state law, or any ruling
  or regulation of any governmental body which the Board shall, in its sole
  discretion, determine to be necessary or advisable, and/or (b) the Optionee
  making at the time of exercise any reasonable representations and warranties
  requested by the Company in order to qualify the issuance of the Option Shares
  for exemptions from registration under state or federal securities laws. The
  Option Shares issued on the exercise of this Option, when paid for as herein
  provided, will be fully paid and non-assessable.

           3. Termination of Employment or Death.

                    (a) In the event of a termination of Optionee's employment
  or consulting services for any reason (other than a termination of an Optionee
  employee by his or her death or disability), (i) except as provided in clause
  (ii) of this sentence this Option shall

  terminate as of the day of notice of such termination by either party, but in
  no event later than the Expiration Date, and (ii) any unexercised portion of
  this Option which is otherwise exercisable on the date of termination may be
  exercised by Optionee at any time within three (3) months following the date
  of such termination, unless Optionee dies during such three (3) month period,
  but in no event later than the Expiration Date. If Optionee is an employee,
  whether military, government or other service by Optionee or other leave of
  absence granted to Optionee shall constitute such a termination shall be
  determined in each case by the Board at its discretion, and any determination
  by the Board shall be final and conclusive. If the Board determines that such
  absence does not constitute such a termination, however, Optionee may exercise
  his or her option only with the consent of the Board.

                    (b) If Optionee is an employee, upon termination of
  Optionee's employment with the Company (including its subsidiaries) as result
  of a permanent disability (as defined by Section 22(e)(3) of the Code), (i)
  except as provided in clause (ii) of this sentence, this Option shall
  terminate and be unexercisable on the date of such termination, but in no
  event later than the Expiration Date, and (ii) any unexercised portion of this
  Option which is otherwise exercisable on the date of such termination may be
  exercised by Optionee at any time within six (6) months following the date of
  such termination, unless Optionee dies during such six (6) month period, but
  in no event later than the Expiration Date.

                    (c) If Optionee is an employee, upon termination of his or
  her employment by the Company without Cause, if there is a written employment
  agreement between Optionee and the Company, this Option shall cease to vest in
  accordance with the Vesting Schedule regardless of any salary continuation
  specified by such employment agreement as a result of such termination. Upon
  termination of his or her employment with the Company, (i) except as provided
  in clause (ii) of this sentence, this Option shall terminate and be
  unexercisable as to unvested options on the date of termination, but in no
  event later than the Expiration Date, and (ii) any unexercised portion of this
  Option which is otherwise exercisable as of such termination date may be
  exercised by Optionee at any time within three (3) months following such
  termination date, unless Optionee dies during such three (3) month period such
  option may be exercised pursuant to subparagraph (d) below, but in no event
  later than the Expiration Date. If there is no

  written employment agreement between Optionee and the Company, upon
  termination of his or her employment by the Company without Cause any
  unexercised portion of this Option shall terminate in accordance with Section
  3(a) above, but in no event later than the Expiration Date.

                    (d) If Optionee dies, (i) except as provided in clause (ii)
  of this sentence, this Option shall terminate and be unexercisable on the date
  of death, and (ii) any unexercised portion of this Option, if otherwise
  exercisable at the date of death, may be exercised by his or her personal
  representatives, heirs, or legatees at any time prior to the expiration of one
  (1) year after the date of Optionee's death, but in no event later than the
  Expiration Date.

           4. Full Information. Optionee represents that he or she is familiar
  with the business and affairs of the Company and realizes that the receipt of
  the Option and Option Shares is a speculative investment and that any possible
  profit therefrom is uncertain. Optionee further represents that he or she has
  had the opportunity to ask questions of and receive answers from the Company
  and any person acting on its behalf and to obtain all information available
  with respect to the Company and its affairs, and has received all information
  and data with respect to the Company that he or she has requested and which he
  or she has deemed relevant in connection with his or her receipt of the Option
  and the Option Shares subject to the Option.

           5. No Rights in Option Stock. Optionee shall have no rights as a
  stockholder with respect to any of the Option Shares prior to the date of
  issuance to the Optionee of a certificate or certificates for such shares.
  Optionee shall have no rights with respect to such shares not expressly
  conferred by this Agreement.

           6. Stock Reserved. The Company shall at all times during the term of
  this Agreement reserve and keep available such number of shares of the Common
  Stock as will be sufficient to satisfy the requirements of this Agreement, and

           7. Nonassignability. This Option shall not be encumbered or
  transferred in whole or in part except by will or the laws of descent and
  distribution and is exercisable during the lifetime of the Optionee only by
  the Optionee.

           8. No Employment. This Agreement shall not give Optionee a right to
  employment by, or membership on the board of directors of, the Company or its
  subsidiaries.

           9. Non-Qualified Option. It is the intent of the parties hereto that
  this Option be a non-qualified stock option and subject to all of the
  applicable provisions of the Internal Revenue Code of 1986, as amended. The
  Company recognizes that the Optionee may be subject to restrictions regarding
  his or her right to trade Common Stock under applicable securities laws.
  Accordingly, the Optionee may want to consider making an election to be taxed
  upon exercise of this Option under Section 83(b) of the Code. The Optionee
  shall have sole discretion to make such an election and shall be solely
  responsible for complying with the Code and all relevant rules and regulations
  in connection with such election. The Optionee shall provide written notice to
  the Company of such election immediately after making such election.

           10. Share Adjustments. If the Company's outstanding shares of Common
  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 the number and kind of shares that
  are subject to this Option and the Exercise Price Per Share, without any
  change in the aggregate price to be paid therefor upon exercise of this
  Option.

           11. Changes in Control.

                    (a) Change in Control. Subject to Section 12, in the event
  that a Change in Control shall occur, then (i) this Option (whether vested or
  not vested) shall automatically become one hundred percent (100%) vested
  immediately, and (ii) no other terms, conditions, restrictions or limitations
  shall be imposed upon this Option after such

  date, and in no circumstance shall this Option be forfeited on or after such
  date.

                    (b) Automatic Acceleration and Cash-Out. Subject to Section
  12, upon a Change in Control that results directly or indirectly in the Common
  Stock (or the stock of any successor the Company received in exchange for
  Common Stock) ceasing to be publicly traded on a national securities market at
  any time, (i) this Option shall automatically become one hundred percent
  (100%) vested immediately with respect to the Option Shares, (ii) no other
  terms, conditions, restrictions or limitations shall be imposed upon this
  Option after such date, and in no circumstance shall this Option be forfeited
  on or after such date, and (iii) this Option shall be valued and cashed out on
  the basis of the Change in Control Price.

                    (c) Section 16 Insider. Notwithstanding anything herein to
  the contrary, if the Optionee is subject to the reporting requirements of
  Section 16 of the Exchange Act with respect to the Company, and on the date of
  the Change in Control this Option has not been outstanding for a period of at
  least six months from the Date of Grant, the Optionee shall not be paid the
  consideration described in this Section 11 above until the first day next
  following the end of such six-month period.

           12. Modification, Extension and Renewal. The Board may modify, renew
  or accept the surrender of this Option, including the acceleration or waiver
  of any vesting or other restrictions or limitations, or the conversion of this
  Option (with appropriate adjustments) to be applicable to the securities of
  any successor corporation to the Company or parent of any such successor, and
  the Board may authorize new options in substitution for the Option. Any
  substituted, modified or converted options may bear such different or
  additional terms and conditions as the Board shall deem appropriate. The
  determination of the Board 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 Board has determined that any event shall not be considered to be
  a Change in Control) and shall be conclusive and binding notwithstanding the
  provisions hereof regarding exercisability. Any fractional shares resulting
  from any of the foregoing adjustments under this Section shall be disregarded
  and eliminated. However, no modification of this Option shall, without the
  consent of

                         ADDITIONAL TERMS AND CONDITIONS
                             RENAL CARE GROUP, INC.
                      NON-QUALIFIED STOCK OPTION AGREEMENT
                             FOR RAYMOND HAKIM, M.D.


           1. Exercise of Option. This Option may be exercised in whole or in
  part, but in no less than one hundred (100) share lots, by written notice, in
  substantially the form as Exhibit 1 hereto, directed to the Secretary of the
  Company at its principal place of business, accompanied by payment of the
  Exercise Price for the number of shares purchased. Payment shall be made in
  cash, by check, or in shares of Common Stock already held by the Optionee
  prior to the exercise of the Option. In the event that all or part of the
  Exercise Price is paid in shares of Common Stock, the value of such shares
  shall be equal to the Fair Market Value of such shares on the date of exercise
  of the Option, and the Optionee shall deliver to the Company a certificate or
  certificates for such shares.

           2. Issuance of Option Shares. Upon a valid exercise of this Option,
  the Company shall, or shall direct its transfer agent to, make delivery of the
  Option Shares as soon as reasonably possible; provided, however, that the
  Company shall not be required to issue or deliver any certificates for Option
  Shares pursuant to this Option prior to (a) the completion of any registration
  or qualification of such shares under any federal or state law, or any ruling
  or regulation of any governmental body which the Board shall, in its sole
  discretion, determine to be necessary or advisable, and/or (b) the Optionee
  making at the time of exercise any reasonable representations and warranties
  requested by the Company in order to qualify the issuance of the Option Shares
  for exemptions from registration under state or federal securities laws. The
  Option Shares issued on the exercise of this Option, when paid for as herein
  provided, will be fully paid and non-assessable.

           3. Termination of Employment or Death.

                    (a) In the event of a termination of Optionee's employment
  or consulting services for any reason (other than a termination of an Optionee
  employee by his or her death or disability), (i) except as provided in clause
  (ii) of this sentence this Option shall

  terminate as of the day of notice of such termination by either party, but in
  no event later than the Expiration Date, and (ii) any unexercised portion of
  this Option which is otherwise exercisable on the date of termination may be
  exercised by Optionee at any time within three (3) months following the date
  of such termination, unless Optionee dies during such three (3) month period,
  but in no event later than the Expiration Date. If Optionee is an employee,
  whether military, government or other service by Optionee or other leave of
  absence granted to Optionee shall constitute such a termination shall be
  determined in each case by the Board at its discretion, and any determination
  by the Board shall be final and conclusive. If the Board determines that such
  absence does not constitute such a termination, however, Optionee may exercise
  his or her option only with the consent of the Board.

                    (b) If Optionee is an employee, upon termination of
  Optionee's employment with the Company (including its subsidiaries) as result
  of a permanent disability (as defined by Section 22(e)(3) of the Code), (i)
  except as provided in clause (ii) of this sentence, this Option shall
  terminate and be unexercisable on the date of such termination, but in no
  event later than the Expiration Date, and (ii) any unexercised portion of this
  Option which is otherwise exercisable on the date of such termination may be
  exercised by Optionee at any time within six (6) months following the date of
  such termination, unless Optionee dies during such six (6) month period, but
  in no event later than the Expiration Date.

                    (c) If Optionee is an employee, upon termination of his or
  her employment by the Company without Cause, if there is a written employment
  agreement between Optionee and the Company, this Option shall cease to vest in
  accordance with the Vesting Schedule regardless of any salary continuation
  specified by such employment agreement as a result of such termination. Upon
  termination of his or her employment with the Company, (i) except as provided
  in clause (ii) of this sentence, this Option shall terminate and be
  unexercisable as to unvested options on the date of termination, but in no
  event later than the Expiration Date, and (ii) any unexercised portion of this
  Option which is otherwise exercisable as of such termination date may be
  exercised by Optionee at any time within three (3) months following such
  termination date, unless Optionee dies during such three (3) month period such
  option may be exercised pursuant to subparagraph (d) below, but in no event
  later than the Expiration Date. If there is no

  written employment agreement between Optionee and the Company, upon
  termination of his or her employment by the Company without Cause any
  unexercised portion of this Option shall terminate in accordance with Section
  3(a) above, but in no event later than the Expiration Date.

                    (d) If Optionee dies, (i) except as provided in clause (ii)
  of this sentence, this Option shall terminate and be unexercisable on the date
  of death, and (ii) any unexercised portion of this Option, if otherwise
  exercisable at the date of death, may be exercised by his or her personal
  representatives, heirs, or legatees at any time prior to the expiration of one
  (1) year after the date of Optionee's death, but in no event later than the
  Expiration Date.

           4. Full Information. Optionee represents that he or she is familiar
  with the business and affairs of the Company and realizes that the receipt of
  the Option and Option Shares is a speculative investment and that any possible
  profit therefrom is uncertain. Optionee further represents that he or she has
  had the opportunity to ask questions of and receive answers from the Company
  and any person acting on its behalf and to obtain all information available
  with respect to the Company and its affairs, and has received all information
  and data with respect to the Company that he or she has requested and which he
  or she has deemed relevant in connection with his or her receipt of the Option
  and the Option Shares subject to the Option.

           5. No Rights in Option Stock. Optionee shall have no rights as a
  stockholder with respect to any of the Option Shares prior to the date of
  issuance to the Optionee of a certificate or certificates for such shares.
  Optionee shall have no rights with respect to such shares not expressly
  conferred by this Agreement.

           6. Stock Reserved. The Company shall at all times during the term of
  this Agreement reserve and keep available such number of shares of the Common
  Stock as will be sufficient to satisfy the requirements of this Agreement, and
  shall pay all original issue taxes on the exercise of this Option, and all
  other fees and expenses necessarily incurred by the Company in connection
  therewith.

           7. Nonassignability. This Option shall not be encumbered or
  transferred in whole or in part except by will or the laws of descent and
  distribution and is exercisable during the lifetime of the Optionee only by
  the Optionee.

           8. No Employment. This Agreement shall not give Optionee a right to
  employment by, or membership on the board of directors of, the Company or its
  subsidiaries.

           9. Non-Qualified Option. It is the intent of the parties hereto that
  this Option be a non-qualified stock option and subject to all of the
  applicable provisions of the Internal Revenue Code of 1986, as amended. The
  Company recognizes that the Optionee may be subject to restrictions regarding
  his or her right to trade Common Stock under applicable securities laws.
  Accordingly, the Optionee may want to consider making an election to be taxed
  upon exercise of this Option under Section 83(b) of the Code. The Optionee
  shall have sole discretion to make such an election and shall be solely
  responsible for complying with the Code and all relevant rules and regulations
  in connection with such election. The Optionee shall provide written notice to
  the Company of such election immediately after making such election.

           10. Share Adjustments. If the Company's outstanding shares of Common
  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 the number and kind of shares that
  are subject to this Option and the Exercise Price Per Share, without any
  change in the aggregate price to be paid therefor upon exercise of this
  Option.

           11. Changes in Control.

                    (a) Change in Control. Subject to Section 12, in the event
  that a Change in Control shall occur, then (i) this Option (whether vested or
  not vested) shall automatically become one hundred percent (100%) vested
  immediately, and (ii) no other terms, conditions, restrictions or limitations
  shall be imposed upon this Option after such

  date, and in no circumstance shall this Option be forfeited on or after such
  date.

                    (b) Automatic Acceleration and Cash-Out. Subject to Section
  12, upon a Change in Control that results directly or indirectly in the Common
  Stock (or the stock of any successor the Company received in exchange for
  Common Stock) ceasing to be publicly traded on a national securities market at
  any time, (i) this Option shall automatically become one hundred percent
  (100%) vested immediately with respect to the Option Shares, (ii) no other
  terms, conditions, restrictions or limitations shall be imposed upon this
  Option after such date, and in no circumstance shall this Option be forfeited
  on or after such date, and (iii) this Option shall be valued and cashed out on
  the basis of the Change in Control Price.

                    (c) Section 16 Insider. Notwithstanding anything herein to
  the contrary, if the Optionee is subject to the reporting requirements of
  Section 16 of the Exchange Act with respect to the Company, and on the date of
  the Change in Control this Option has not been outstanding for a period of at
  least six months from the Date of Grant, the Optionee shall not be paid the
  consideration described in this Section 11 above until the first day next
  following the end of such six-month period.

           12. Modification, Extension and Renewal. The Board may modify, renew
  or accept the surrender of this Option, including the acceleration or waiver
  of any vesting or other restrictions or limitations, or the conversion of this
  Option (with appropriate adjustments) to be applicable to the securities of
  any successor corporation to the Company or parent of any such successor, and
  the Board may authorize new options in substitution for the Option. Any
  substituted, modified or converted options may bear such different or
  additional terms and conditions as the Board shall deem appropriate. The
  determination of the Board 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 Board has determined that any event shall not be considered to be
  a Change in Control) and shall be conclusive and binding notwithstanding the
  provisions hereof regarding exercisability. Any fractional shares resulting
  from any of the foregoing adjustments under this Section shall be disregarded
  and eliminated. However, no modification of this Option shall, without the
  consent of

                         ADDITIONAL TERMS AND CONDITIONS
                             RENAL CARE GROUP, INC.
                      NON-QUALIFIED STOCK OPTION AGREEMENT
                                FOR RONALD HINDS


           1. Exercise of Option. This Option may be exercised in whole or in
  part, but in no less than one hundred (100) share lots, by written notice, in
  substantially the form as Exhibit 1 thereto, directed to the Secretary of the
  Company at its principal place of business, accompanied by payment of the
  Exercise Price for the number of shares purchased. Payment shall be made in
  cash, by check, or in shares of Common Stock already held by the Optionee
  prior to the exercise of the Option. In the event that all or part of the
  Exercise Price is paid in shares of Common Stock, the value of such shares
  shall be equal to the Fair Market Value of such shares on the date of exercise
  of the Option, and the Optionee shall deliver to the Company a certificate or
  certificates for such shares.

           2. Issuance of Option Shares. Upon a valid exercise of this Option,
  the Company shall, or shall direct its transfer agent to, make delivery of the
  Option Shares as soon as reasonably possible; provided, however, that the
  Company shall not be required to issue or deliver any certificates for Option
  Shares pursuant to this Option prior to (a) the completion of any registration
  or qualification of such shares under any federal or state law, or any ruling
  or regulation of any governmental body which the Board shall, in its sole
  discretion, determine to be necessary or advisable, and/or (b) the Optionee
  making at the time of exercise any reasonable representations and warranties
  requested by the Company in order to qualify the issuance of the Option Shares
  for exemptions from registration under state or federal securities laws. The
  Option Shares issued on the exercise of this Option, when paid for as herein
  provided, will be fully paid and non-assessable.

           3. Termination of Employment or Death.

                    (a) In the event of a termination of Optionee's employment
  or consulting services for any reason (other than a termination of an Optionee
  employee by his or her death or disability), (i) except as provided in clause
  (ii) of this sentence this Option shall

                                                [OFFICERS/EMPLOYEES/CONSULTANTS]


  terminate as of the day of notice of such termination by either party, but in
  no event later than the Expiration Date, and (ii) any unexercised portion of
  this Option which is otherwise exercisable on the date of termination may be
  exercised by Optionee at any time within three (3) months following the date
  of such termination, unless Optionee dies during such three (3) month period,
  but in no event later than the Expiration Date. If Optionee is an employee,
  whether military, government or other service by Optionee or other leave of
  absence granted to Optionee shall constitute such a termination shall be
  determined in each case by the Board at its discretion, and any determination
  by the Board shall be final and conclusive. If the Board determines that such
  absence does not constitute such a termination, however, Optionee may exercise
  his or her option only with the consent of the Board.

                    (b) If Optionee is an employee, upon termination of
  Optionee's employment with the Company (including its subsidiaries) as result
  of a permanent disability (as defined by Section 22(e)(3) of the Code), (i)
  except as provided in clause (ii) of this sentence, this Option shall
  terminate and be unexercisable on the date of such termination, but in no
  event later than the Expiration Date, and (ii) any unexercised portion of this
  Option which is otherwise exercisable on the date of such termination may be
  exercised by Optionee at any time within six (6) months following the date of
  such termination, unless Optionee dies during such six (6) month period, but
  in no event later than the Expiration Date.

                    (c) If Optionee is an employee, upon termination of his or
  her employment by the Company without Cause, if there is a written employment
  agreement between Optionee and the Company, this Option shall cease to vest in
  accordance with the Vesting Schedule regardless of any salary continuation
  specified by such employment agreement as a result of such termination. Upon
  termination of his or her employment with the Company, (i) except as provided
  in clause (ii) of this sentence, this Option shall terminate and be
  unexercisable as to unvested options on the date of termination, but in no
  event later than the Expiration Date, and (ii) any unexercised portion of this
  Option which is otherwise exercisable as of such termination date may be
  exercised by Optionee at any time within three (3) months following such
  termination date, unless Optionee dies during such three (3) month period such
  option may be exercised pursuant to subparagraph (d) below, but in no event
  later than the Expiration Date. If there is no

                                                [OFFICERS/EMPLOYEES/CONSULTANTS]


  written employment agreement between Optionee and the Company, upon
  termination of his or her employment by the Company without Cause any
  unexercised portion of this Option shall terminate in accordance with Section
  3(a) above, but in no event later than the Expiration Date.

                    (d) If Optionee dies, (i) except as provided in clause (ii)
  of this sentence, this Option shall terminate and be unexercisable on the date
  of death, and (ii) any unexercised portion of this Option, if otherwise
  exercisable at the date of death, may be exercised by his or her personal
  representatives, heirs, or legatees at any time prior to the expiration of one
  (1) year after the date of Optionee's death, but in no event later than the
  Expiration Date.

           4. Full Information. Optionee represents that he or she is familiar
  with the business and affairs of the Company and realizes that the receipt of
  the Option and Option Shares is a speculative investment and that any possible
  profit therefrom is uncertain. Optionee further represents that he or she has
  had the opportunity to ask questions of and receive answers from the Company
  and any person acting on its behalf and to obtain all information available
  with respect to the Company and its affairs, and has received all information
  and data with respect to the Company that he or she has requested and which he
  or she has deemed relevant in connection with his or her receipt of the Option
  and the Option Shares subject to the Option.

           5. No Rights in Option Stock. Optionee shall have no rights as a
  stockholder with respect to any of the Option Shares prior to the date of
  issuance to the Optionee of a certificate or certificates for such shares.
  Optionee shall have no rights with respect to such shares not expressly
  conferred by this Agreement.

           6. Stock Reserved. The Company shall at all times during the term of
  this Agreement reserve and keep available such number of shares of the Common
  Stock as will be sufficient to satisfy the requirements of this Agreement, and
  shall pay all original issue taxes on the exercise of this Option, and all
  other fees and expenses necessarily incurred by the Company in connection
  therewith.

           7. Nonassignability. This Option shall not be encumbered or
  transferred in whole or in part except by will or the laws of descent and
  distribution and is exercisable during the lifetime of the Optionee only by
  the Optionee.

           8. No Employment. This Agreement shall not give Optionee a right to
  employment by, or membership on the board of directors of, the Company or its
  subsidiaries.

           9. Non-Qualified Option. It is the intent of the parties hereto that
  this Option be a non-qualified stock option and subject to all of the
  applicable provisions of the Internal Revenue Code of 1986, as amended. The
  Company recognizes that the Optionee may be subject to restrictions regarding
  his or her right to trade Common Stock under applicable securities laws.
  Accordingly, the Optionee may want to consider making an election to be taxed
  upon exercise of this Option under Section 83(b) of the Code. The Optionee
  shall have sole discretion to make such an election and shall be solely
  responsible for complying with the Code and all relevant rules and regulations
  in connection with such election. The Optionee shall provide written notice to
  the Company of such election immediately after making such election.

           10. Share Adjustments. If the Company's outstanding shares of Common
  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 the number and kind of shares that
  are subject to this Option and the Exercise Price Per Share, without any
  change in the aggregate price to be paid therefor upon exercise of this
  Option.

           11. Changes in Control.

                    (a) Change in Control. Subject to Section 12, in the event
  that a Change in Control shall occur, then (i) this Option (whether vested or
  not vested) shall automatically become one hundred percent (100%) vested
  immediately, and (ii) no other terms, conditions, restrictions or limitations
  shall be imposed upon this Option after such 





                                       6

  date, and in no circumstance shall this Option be forfeited on or after such
  date.

                    (b) Automatic Acceleration and Cash-Out. Subject to Section
  12, upon a Change in Control that results directly or indirectly in the Common
  Stock (or the stock of any successor the Company received in exchange for
  Common Stock) ceasing to be publicly traded on a national securities market at
  any time, (i) this Option shall automatically become one hundred percent
  (100%) vested immediately with respect to the Option Shares, (ii) no other
  terms, conditions, restrictions or limitations shall be imposed upon this
  Option after such date, and in no circumstance shall this Option be forfeited
  on or after such date, and (iii) this Option shall be valued and cashed out on
  the basis of the Change in Control Price.

                    (c) Section 16 Insider. Notwithstanding anything herein to
  the contrary, if the Optionee is subject to the reporting requirements of
  Section 16 of the Exchange Act with respect to the Company, and on the date of
  the Change in Control this Option has not been outstanding for a period of at
  least six months from the Date of Grant, the Optionee shall not be paid the
  consideration described in this Section 11 above until the first day next
  following the end of such six-month period.

           12. Modification, Extension and Renewal. The Board may modify, renew
  or accept the surrender of this Option, including the acceleration or waiver
  of any vesting or other restrictions or limitations, or the conversion of this
  Option (with appropriate adjustments) to be applicable to the securities of
  any successor corporation to the Company or parent of any such successor, and
  the Board may authorize new options in substitution for the Option. Any
  substituted, modified or converted options may bear such different or
  additional terms and conditions as the Board shall deem appropriate. The
  determination of the Board 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 Board has determined that any event shall not be considered to be
  a Change in Control) and shall be conclusive and binding notwithstanding the
  provisions hereof regarding exercisability. Any fractional shares resulting
  from any of the foregoing adjustments under this Section shall be disregarded
  and eliminated. However, no modification of this Option shall, without the
  consent of
