                       MEDICAL DIRECTOR SERVICES AGREEMENT

      THIS MEDICAL DIRECTOR SERVICES AGREEMENT (the "Agreement") is made and
entered into this 14th day of August 2003, effective as of the February 12,
2003, by and between RENAL CARE GROUP TEXAS, INC., a Texas corporation (the
"Company"), and TYLER NEPHROLOGY ASSOCIATES, P.A., a Texas professional
corporation (the "Practice"). In addition, each Practice Physician, as defined
below, has executed the attached Physician Joinder and by which each such
Practice Physician has agreed to be bound by certain terms of this Agreement as
provided in the Physician Joinder.

                              W I T N E S S E T H:

      WHEREAS, the Company owns and operates the renal dialysis facilities at
the addresses shown on EXHIBIT A (collectively, the "Facilities" and,
individually, the "Facility"), which provide outpatient and home dialysis
services;

      WHEREAS, the Facilities are outpatient dialysis facilities certified by
the Center for Medicare and Medicaid Services ("CMS") for payment under the
Medicare program, which program requires each Facility to obtain the services of
a physician or group of physicians to perform prescribed medical director
services for such Facility;

      WHEREAS, the Company desires to engage one or more nephrologists skilled
in dialysis center administration to provide medical director services at the
Facilities in accordance with the requirements established by CMS and as
provided in this Agreement;

      WHEREAS, the Practice desires and is qualified to provide the medical
director services contemplated by this Agreement to the Facilities through one
or more of its Practice Physicians, each of whom will be licensed to Practice
medicine and prescribe drugs without restriction in the State of Texas, will
specialize in nephrology and dialysis services and will be experienced in
dialysis center administration.

      NOW, THEREFORE, in consideration of the premises set forth above and the
mutual covenants and agreements of the parties set forth in this Agreement, the
receipt and sufficiency of which are acknowledged, the parties agree as follows:

                                    ARTICLE I
                             ENGAGEMENT AND SERVICES

      1.1 Engagement. The Company engages the Practice to provide, and the
Practice shall provide, services for the Company as medical director of the
Facilities in accordance with the requirements of applicable CMS regulations
(including, without limitation, 42 C.F.R. Section 405.2100 et seq. and any
successor regulations) and all applicable state regulations, as the same may be
amended or supplemented, together with such other services as are customarily
performed by medical directors at high quality dialysis facilities and such
other tasks related to the oversight of dialysis treatments administered at the
Facilities as the Company may from time to time reasonably designate.

      1.2 Responsibilities. Without limiting the generality of this Article I,
the Practice shall provide the medical director services described in EXHIBIT B,
which may be revised and updated from time to time by the Company, provided that
any change that is not a CMS or other legal requirement must first be approved
by the Practice if it increases the medical director duties hereunder.
<PAGE>
      1.3 Principal Contact. The Practice shall from time to time designate in
writing to the Company a Practice Physician to serve as the principal contact at
each Facility and who shall provide or arrange for the provision of the services
required hereunder, and who shall serve as the principal contact for a period of
no less than 12 months. The Practice may change the designation of the principal
contact with the written consent of the Company (such written consent not to be
unreasonably withheld or delayed); provided that the Practice will not change
the principal contact more often than once per 12-month period, unless the
principal contact dies, becomes disabled, leaves the Practice or experiences
other exigent circumstances. The initial principal contact for each Facility is
set forth on Exhibit A.

      1.4 Patient Care Manual.  The Practice shall advise the Company in
developing, maintaining and implementing a patient care policy and procedures
manual for each Facility describing:

          (a) The types of dialysis used in the Facility and the procedures to
be followed in performing each type of dialysis;

          (b) Procedures for implementing universal precautions for the
prevention of disease transmission;

          (c) Procedures for properly handling blood-borne and infectious
pathogens; and

          (d) A disaster readiness plan.

      1.5 Records. The Company and the Practice acknowledge that attending
physicians have medical responsibility for the content of medical records of
each Facility and that the head nurse of each Facility has operational
responsibility for the day-to-day maintenance of such Facility's records. The
Company, through a medical records supervisor designated for the Facility, with
the assistance and support of the Practice, shall oversee the maintenance of
current medical and business records relating to the care and treatment of
patients in the Facilities in accordance with Company policies and applicable
regulations of governmental agencies, including:

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

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

          (c) Progress notes by all patient care staff, and complete and legibly
signed orders and discharge summaries.

      1.6 Documentation. The Practice and Practice Physicians who provide
services hereunder shall maintain, and provide to the Company upon request,
reasonably complete and detailed documentation of the time spent and services
performed in providing medical director services under this Agreement. This
documentation shall be maintained in a form reasonably satisfactory to or
prescribed by the Company.

      1.7 Medical Staff. The Practice shall review the applications of
physicians requesting to attend to patients at each Facility and forward a
recommendation concerning such applications to the body making credentialing
decisions for the Facility under its Professional Staff Bylaws. Subject to each
Facility's Professional Staff Bylaws, the Practice 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.

                                     - 2 -

      1.8 Coverage. The Practice shall make available one or more Practice
Physicians, as appropriate, to provide medical director services at each
Facility for its hours of operation. The Practice and the Company shall confer
from time to time in good faith concerning the appropriate level of physician
coverage to provide medical director services hereunder.

      1.9 Practice Physicians. (a) The Practice represents and warrants that all
physicians who as of the date of this Agreement meet the definition of a
Practice Physician have executed the Physician Joinder attached hereto. As a
condition to engaging any physician in a manner that causes such physician to
become a Practice Physician, the Practice shall obtain the signature of such
physician on the Physician Joinder in consideration for such engagement the fees
payable to the Practice hereunder.

          (b) For purposes of this Agreement, the term "Practice Physician"
means any physician who is a physician performing services on behalf of the
Practice at any of the Facilities (whether as an employee, partner, member,
shareholder or independent contractor of the Practice), any other physician
performing services on behalf of the Practice hereunder (as may be approved by
the Company), and any other physician in any way affiliated or associated with
the Practice, or regularly seeing patients of the Practice (other than on a
covering or locum tenens basis).

      1.10 No Required Referrals. Notwithstanding any other provision of this
Agreement, each of the Company, the Practice and the Practice Physicians
acknowledges and agrees that neither the Practice nor any Practice Physician is
required to make referrals of patients to the Company or any affiliate of the
Company or to the Facilities. Each of the Practice Physicians is free to
maintain professional staff privileges at any dialysis facility, to refer
patients to any other facility for dialysis or other services, and, subject to
Article VII, otherwise to perform professional medical services at or through
any entity, whether or not it is competing with any Facility, the Company or
with any affiliates of the Company.

      1.11 Supervising Nurse. The Company shall provide a full-time nurse to
manage the provision of patient care in each Facility. The Practice may delegate
to the supervising nurse the responsibility for the execution of patient care
policies on a day-to-day basis, and the principal contact will provide medical
guidance to the supervising nurse in the execution of these duties; provided,
however, that the Practice may only delegate to the supervising nurse duties
covered by this Agreement.

                                   ARTICLE II
                              TERM AND TERMINATION

      2.1 Initial and Renewal Terms. This Agreement is effective as of February
12, 2003, (the "Effective Date") and shall remain in full force and effect until
12:00 p.m. midnight on the seventh anniversary of the Effective Date (the
"Initial Term"), unless earlier terminated as provided in this Article II. This
Agreement shall automatically renew for additional successive terms of three
years each (the "Renewal Terms"), unless either party gives written notice of
non-renewal to the other party not less than 90 days prior to the expiration of
the Initial Term or then-current Renewal Term, as applicable. If such notice is
given, this Agreement shall expire as of the last day of the Initial Term or the
then-current Renewal Term, as applicable.

this Agreement under this Section 2.3(a)(v); or

              (vi) the existence of an immediate threat to the health or safety
of any patient receiving treatment at the Facility, which threats results from
any act or omission of the Company or any of its employees (and not from any act
or omission of the Practice).

          (b) Upon the occurrence of any event described in Section 2.3(a)(iii),
or 2.3(a)(iv), the Practice shall not terminate this Agreement, if, within 30

breach with reasonable particularity.

          (b) Upon the occurrence of any event described in paragraph (a) of
this Section 2.4 that is the result of an act or omission of one or more
specific Practice Physicians who do not constitute a majority of the Practice
Physicians then providing services hereunder, the Company shall not terminate
this Agreement if, within 30 days after the Company gives the Practice written
notice of the act or omission giving the Company the right to terminate this
Agreement, the Practice agrees that any Practice Physician who is the subject of

      2.5 Effect of Termination or Expiration. Upon and following the expiration
of this Agreement or its termination for any reason, the Practice shall not
interfere with any efforts by the Company to contract with any other individual
or entity for the provision of medical director services. Expiration or
termination of this Agreement shall not affect any rights or obligations of the
parties accruing hereunder through the date of expiration or termination,
including the Company's obligation to compensate Practice for medical director
services pro-rated through such date, and such rights and obligations shall
survive expiration or termination.

                                   ARTICLE III
                                  COMPENSATION

      3.1 Compensation.

          (a) In consideration of the services, covenants, and agreements agreed
to be performed by the Practice during the Initial Term and any Renewal Term,
the Company shall pay the Practice at the rate of $532,000 per year, payable in
substantially equal monthly installments on or before the 15th day of each month
for services rendered during the preceding month. In addition to the monthly
medical director fee prescribed above, the Practice shall be eligible for an
annual bonus of up to 15% of the base medical director compensation paid during
the year based upon the success of the Facilities in meeting annual clinical
outcomes targets and in achieving performance objectives for the Facilities and
the Practice generally prescribed by RCG for its dialysis facilities in the
region in which the Facilities are located. Such annual bonus (if any) shall be
payable on or before July 1 for the prior year's services. The current criteria
for reviewing and determining the bonus amount are attached hereto as EXHIBIT C.
RCG may change such criteria annually, and the Company will provide the revised
criteria to the Practice when adopted. The Practice agrees to accept the payment
under this subsection (a) (as it may be adjusted as provided below) as the total
compensation for all services, covenants and agreements pursuant to this
Agreement.

          (b) (i) Beginning effective as of the second anniversary of the
Effective Date, if either party believes that the fair market value of the
services provided by the Practice under this Agreement has changed in any
material way since the most recent anniversary of the Effective Date, then such
party may notify the other that it believes such a change has occurred and the
Practice and the Company shall negotiate in good faith an adjustment to the
compensation described in Section 3.1(a) above so that it represents fair market
value for the duties and responsibilities of the Practice to be provided during
the next year under this Agreement. Notwithstanding the foregoing, no adjustment
pursuant to this subsection (b)(i) to the compensation payable under this
Agreement shall be effective unless set forth in writing signed by each of the
Practice and the Company, which writing shall be deemed an amendment to this
Agreement. The parties hereto agree that any additional compensation paid to the
Practice pursuant to this Agreement in connection with additional renal dialysis
facilities developed or acquired by the Company after the Effective Date shall
be no less than $30,000 per facility, per annum.

              (ii) If the Practice and the Company are unable to agree on an
adjustment, then either may require that an adjustment of the compensation
hereunder be submitted to a qualified independent third party mutually selected
by both the Practice and the Company to determine the fair market value of the
services required hereunder, the costs and fees of which shall be borne equally
by the Practice and the Company. If the Practice and the Company are unable to
agree on the third party, then each such party shall at its own cost and expense
select its own qualified independent third party and the average of such two
determinations of fair market value shall be the revised compensation unless
such determinations are more than 10% apart, in which case such third parties
shall mutually select an additional qualified independent third party, the fees
and expenses of which shall be shared equally, who shall determine the fair
market

                                     - 6 -
<PAGE>
value of the services hereunder from between the range of the amounts determined
by the first two appraisals. The fair market value of the services as determined
in accordance with the provisions of this subsection (b)(ii) shall be the
compensation payable under this Agreement effective as of the applicable
anniversary of the Effective Date, and such final determination shall be deemed
an amendment to this Agreement.

          (c) Any change to the compensation payable hereunder in accordance
with subsection (b) of this Section 3.1 shall be effective as of the applicable
anniversary of the Effective Date and shall remain effective, and not subject to
adjustment under Section 3.1(b) or otherwise, for at least 12 months from the
effective date of such change.

          (d) In further consideration of the Practice's execution and delivery
of this Agreement and the services, covenants and agreements of the Practice and
the Practice Physicians pursuant to this Agreement, the Company shall pay the
Practice a signing bonus of $600,000 (the "Signing Bonus"). The Signing Bonus
will be payable $100,000 in cash by wire transfer to one or more accounts
designated by the Practice, which wire transfer will be made and upon the
Practice's execution and delivery of this Agreement, and $500,000, plus interest
in the amount of 5% per annum, in substantially equal monthly installments of
$7,066.96, in arrears on or before the 15th of each month during the Initial
Term.

      3.2 Expenses. The Company shall be responsible for all reasonable expenses
incurred in the operation of the Facility and the support of the services
provided by Practice hereunder, including appropriate office space and
secretarial support, and shall reimburse the Practice for all reasonable
out-of-pocket expenses incurred by the Practice in attending meetings outside
the service area of the Facility as required or requested by the Company
pursuant to Article I of this Agreement. The Company and the Practice
acknowledge and agree that attendance by existing medical directors at RCG's
annual medical meeting is not required under this Agreement. The Company will
pay the Practice $1,000 each year to help defray the cost of one or more
Practice Physicians attending RCG's annual medical meeting if one or more
Practice Physicians attend such annual meeting.

                                   ARTICLE IV
                                STATUS OF PARTIES

      4.1 Tax Status. The Company and the Practice acknowledge and agree that
the relationship created under this Agreement between them is that of
independent contractors and that nothing in this Agreement shall be deemed to
render either party the employer or employee of the other, agent or principal of
the other, or joint venturer or partner of the other. The parties acknowledge
and agree that the Practice Physicians will be engaged by the Practice and will
under no circumstances be considered the employee(s) of the Company, RCG or the
Facilities, or any of their affiliates. The Practice shall be responsible for
all withholding, payroll and similar taxes related to its engagement of the
Practice Physicians, and neither the Practice nor the Practice Physicians shall
be entitled to any benefits afforded to the employees of the Company, RCG or the
Facilities, or any of their affiliates. The Practice agrees that (i) neither it
nor any Practice Physician be treated as an employee of the Company for federal
tax purposes; (ii) the Company will not withhold on behalf of the Practice any
sums for income tax, unemployment insurance, social security, or any other
withholding pursuant to any law or requirement of any governmental body; (iii)
all of such taxes, payments and withholdings, if any, are the sole
responsibility of the Practice; and (iv) the Practice will indemnify and hold
the Company and RCG harmless from any and all loss or liability arising with
respect to such benefits, taxes, payments and withholdings, if any. If the
United States Internal Revenue Service ("IRS") should question or challenge the
worker status of the Practice or the Practice Physicians, then the parties agree
that both the Practice and the Company shall have the right to participate in
any discussion or negotiation

                                     - 7 -
<PAGE>
occurring with the IRS, irrespective of which party initiated such discussions
or negotiations, and each party shall notify the other in advance of any planned
meeting or discussion.

      4.2 No Agency. The Practice shall not have the right or authority to, and
expressly agrees that it will not, enter into any contract in the name of the
Company or otherwise to bind the Company, in any way, without the express
written consent of the Company. The Practice shall indemnify and hold the
Company harmless from any and all loss or liability attributable to a violation
of this covenant.

      4.3 Access to Records. If it is ultimately determined that Section 952 of
the Omnibus Reconciliation Act of 1980 (42 CFR 420.300 et seq.) applies to this
Agreement, then until the expiration of four years after the furnishing of
services provided under this Agreement, the Practice 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 Practice 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.

      4.4 The Company's Work Product. All operating procedures, protocols,
information systems, operating data, databases, reports and other non-public
proprietary business systems or information owned by the Company or RCG shall be
and remain the exclusive property of the Company or RCG, as appropriate. If the
Practice or any Practice Physician modifies, enhances or alters any of such
property such modification, enhancement or alteration will be deemed a
work-for-hire and shall be the property of the Company or RCG, as appropriate.
The Practice or Practice Physician making such modification, enhancement or
alteration will execute all documents reasonably requested by the Company to
vest fully in the Company or RCG title to such modification, enhancement or
alteration.

                                    ARTICLE V
                                    INSURANCE

      5.1 Practice Insurance Coverage. The Practice shall purchase and maintain
at its expense for itself and each of the Practice Physicians professional and
general liability insurance, with an insurance company reasonably acceptable to
the Company, with policy limits of at least $1,000,000 per occurrence and
$3,000,000 in the aggregate for each of the Practice Physicians and policy
limits of at least $200,000 per occurrence and $600,000 in the aggregate for the
Practice, including coverage for acts and omissions in performing services under
this Agreement and in rendering medical services to patients of the Facilities.

      5.2 Company Insurance Coverage. The Company shall procure and maintain
throughout the term of this Agreement professional and general customary
liability insurance (through self-insurance or an insurance carrier) with policy
limits of at least $1,000,000 per occurrence and $3,000,000 in the aggregate.

      5.3 Evidence of Coverage. Upon the execution of this Agreement and
annually thereafter or on reasonable request, the Company and the Practice shall
each provide the other with certificates of insurance or other reasonably
satisfactory evidence of the insurance required to be maintained under Sections
5.1 and 5.2. Each party shall notify the other at least 60 days prior to the
voluntary cancellation or termination of any such coverage and immediately upon
receipt of any notice of involuntary cancellation or termination of any such
coverage.

          (h) The Practice has notified the Company of each action or claim
alleging professional negligence filed or asserted against the Practice or any

                                   ARTICLE VII
                         CONFIDENTIALITY, NONCOMPETITION
                          AND NONSOLICITATION COVENANT

      7.1 Additional Covenants.

          (a) During the term of this Agreement and for a period of two years
after the termination or expiration of this Agreement, the Practice and each
Practice Physician agrees that it, he or she will not in any manner, directly or
indirectly, by itself, himself or herself or in conjunction with any other
person, (i) conduct any of the activities or perform any of the responsibilities
delineated in Article I and EXHIBIT B ("Services") of this Agreement for any
business entity that is competitive with the business of the Company 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 a 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, in either case within a 25-mile radius around each Facility (the
"Territory"). For purposes of this Article, the "business of the Company" means
owning or operating a renal dialysis center, unit or facility or providing
dialysis supplies or services to any other such center, unit or facility to any
home dialysis program, including the provision of pharmaceuticals or laboratory
services related to renal dialysis, but does not include participating, directly
or indirectly, as a limited partner in RCG East Texas, LLP.

          By executing a counterpart of this Agreement and in consideration of
the compensation paid to the Practice hereunder, each Practice Physician agrees
to be bound by the terms of this Article VII. With respect to the Practice
Physicians, the two year time periods applicable to this Article VII shall begin
on the earlier of (i) the termination or expiration of this Agreement, or (ii)
the termination of the employment, independent contractor or other relationship
or affiliation of the Practice Physician with the Practice, such that such
Practice Physician ceases to fall within the definition of a Practice Physician
hereunder and generally ceases to treat patients of the Practice.

          (b) During the term of this Agreement and for a period of two years
after the termination or expiration of this Agreement, the Practice and each
Practice Physician will use all reasonable efforts to keep confidential and not
to divulge, or allow to be divulged to anyone, or use or otherwise appropriate
for its, his or her own benefit or for the benefit of others, any knowledge or
information of a confidential nature with respect to the business of the
Company, 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) information
that is generally available to the public other than as a result of a breach of
a confidentiality agreement, (ii) information available on a non-confidential
basis from a source other than the Company or its affiliates or agents, which
source itself is not bound by a confidentiality agreement, (iii) information
required to be disclosed by law or pursuant to court order, but only to the
extent such disclosure is necessary to respond to such law or court order, or
(iv) disclosure necessary in order for the Practice to perform its obligations
under this Agreement, but only to the extent

                                     - 10 -
<PAGE>
such disclosure is necessary for such performance. Each of the Practice and the
Practice Physician 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 that the Company may have available pursuant to
the laws of any jurisdiction or at common law to prevent the disclosure of
confidential information or trade secrets, and the enforcement by the Company of
its rights and remedies under to this Agreement shall not be construed as a
waiver of any other rights or available remedies that the Company may possess in
law or equity.

          (c) During the term of this Agreement and for a period of two years
after the termination or expiration of this Agreement, neither the Practice nor
any of the Practice Physicians will, for its, his or her 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 payor, physician, provider, managed care organization or
supplier) at any time during the term of this Agreement for the purpose of
assisting or creating such a relationship for any business entity that is
competitive with the business of the Company.

          (d) During the term of this Agreement and for a period of two years
after the termination of this Agreement, no party hereto will hire or attempt to
hire, or induce, or attempt to induce, any employee of another party or any of
its affiliates to terminate his or her association with such other party or any
of its affiliates. If any employee of a party hereto or any of its affiliates
(the "Non-Hiring Party") responds to a general solicitation and seeks employment
with another party or any of its affiliates (the "Hiring Party"), and the Hiring
Party desires to hire such employee, then the Hiring Party shall give notice of
its, his or her desire to hire such employee to the Non-Hiring Party and will
not offer to hire such employee until the earlier of seven days after such
notice is received by the Non-Hiring Party or the date on which the Non-Hiring
Party approves such hiring. If the Hiring Party hires an employee of the
Non-Hiring Party after following the procedures outlined above, the Non-Hiring
Party may request that the employee continue to provide services to the
Non-Hiring Party for up to 30 days to provide for an orderly transition.

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

          (f) Nothing in this Article VII shall be deemed to prohibit any
Practice Physician from exercising his or her 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 parties acknowledge
and agree that this Agreement shall in no way be deemed to restrict the right or
ability of the Practice and the Practice Physicians to admit and provide
professional service to patients at facilities and institutions other than the
Facilities or other facilities of the Company or RCG, including without
limitation facilities operated by business entities that are competitive with
the business of the Company. The Practice and the Practice Physicians
acknowledge that enforcement of this covenant will not prevent any physician of
the Practice from earning a living by practicing medicine or nephrology.

                                  ARTICLE VIII
                       CONFIDENTIALITY OF PATIENT RECORDS

                                     - 11 -
<PAGE>
      8.1 Patient Records. (a) All patient medical records shall be and remain
the sole property of the Company and shall be maintained at the Facilities. The
Practice shall assist the Company in implementing procedures to preserve the
confidentiality of patient medical records and shall cooperate in compiling data
regarding patient treatment costs and outcomes.

          (b) Neither the Practice nor any Practice Physician shall disclose to
any third party, except where permitted or required by law or where such
disclosure is expressly approved by the Company in writing, any patient or
medical record information regarding patients of the Company, and the Practice
and the Practice Physicians shall comply with all federal and state laws and
regulations and with the policies of the Company regarding the confidentiality
of such information. Each party acknowledges that in receiving or otherwise
dealing with any records or information from the other party about a Facility's
patients receiving treatment for alcohol or drug abuse, each party are fully
bound by the provisions of the federal regulations governing Confidentiality of
Alcohol and Drug Abuse Patient Records (42 C.F.R. Part 2, as amended from time
to time).

          (c) The Company, the Practice and the Practice Physicians agree to
comply with the applicable provisions of the Administrative Simplification
section of the Health Insurance Portability and Accountability Act of 1996, as
codified at 42 U.S.C. Section 1320d through d-8 ("HIPAA"), and the requirements
of any regulations promulgated thereunder including without limitation the
federal privacy regulations as contained in 45 CFR Part 164 (the "Federal
Privacy Regulations") and the federal security standards as contained in 45 CFR
Part 142 (the "Federal Security Regulations"). The Company, the Practice and the
Practice Physicians agree not to use or further disclose any protected health
information, as defined in 45 CFR 164.504, or individually identifiable health
information, as defined in 42 U.S.C. Section 1320d (collectively, the "Protected
Health Information"), concerning a patient other than as permitted by this
Agreement and the requirements of HIPAA or regulations promulgated under HIPAA
including without limitation the Federal Privacy Regulations and the Federal
Security Regulations. The Practice and the Practice Physicians will assist the
Company in implementing appropriate safeguards to prevent the use or disclosure
of a patient's Protected Health Information other than as provided for by this
Agreement, and the Practice and the Practice Physicians will abide by the
policies and procedures adopted by the Company with respect to the Protected
Health Information of the Facility's patients. Each of the Practice Physicians
and the Practice will promptly report to the other any use or disclosure of a
Company patient's Protected Health Information not provided for by this
Agreement or in violation of HIPAA, the Federal Privacy Regulations, or the
Federal Security Regulations of which the Practice or the Practice Physician
becomes aware. In the event the Practice or any Practice Physician, with the
Company's approval, contracts with any agents to whom the Company provides a
patient's Protected Health Information, the Practice or the Practice Physician
shall include provisions in such agreements whereby the Practice or the Practice
Physician and such agent agree to the same restrictions and conditions that
apply to the Practice and the Practice Physicians with respect to such patient's
Protected Health Information. The Practice and the Practice Physicians will make
their internal practices, books, and records relating to the use and disclosure
of a patient's Protected Health Information available to the Secretary of Health
and Human Services to the extent required for determining compliance with the
Federal Privacy Regulations and the Federal Security Regulations.
Notwithstanding the foregoing, no attorney-client, accountant-client, or other
legal privilege shall be deemed waived by the Company, RCG, the Practice or any
Practice Physician by virtue of this subsection.

          (d) The provisions of this Section 8.1 shall survive expiration or
other termination of this Agreement, regardless of the cause of such
termination.

                                and General Counsel

      Any party hereto may change its address specified for notices herein by
designating a new address by notice in accordance with this Section 9.1.

      9.2 Amendments. Subject to Section 9.4, this Agreement may be amended at
any time by mutual agreement of the Practice and the Company hereto, but any
such amendment shall not be operative or valid unless the same is reduced to
writing and approved by the parties hereto.

      9.3 Assignability. This Agreement shall not be assignable by the Practice,
and the Practice shall not assign any of its rights or obligations under this
Agreement without the written consent of the Company. This Agreement shall not
be assignable by the Company, and the Company shall not assign any of its rights
or obligations under this Agreement without the written consent of the Practice;
provided that, without the consent of Practice, the Company may assign or
transfer this Agreement to an affiliate of the Company or RCG or in connection
with a sale of the Facilities or all or substantially all of the assets or
business of the Company.

      9.4 Contract Modifications; Severability.

          (a) This Agreement shall be construed to the fullest extent possible
to be in compliance with and permitted by all Federal (including Medicare and
Medicaid) and state statutes, rules and regulations. If a Triggering Event (as
defined below) occurs, either the Company or the Practice may by written notice
to the other propose an amendment to this Agreement as necessary to comply with
the item giving rise to the Triggering Event. To the fullest extent possible,
any such amendment shall preserve the responsibilities and duties of the parties
and the underlying economic and financial arrangements between the Company and
the Practice with the least changes to the parties' expectations hereunder. If
the Practice and the Company fail to agree to the form of an amendment within 60
days after the date of such notice, then either of such party may submit the
matter to arbitration as provided in Section 9.9, and any arbitration award
shall comply with

                                     - 13 -
<PAGE>
the second sentence of this Section; provided that if any resulting change to
this Agreement includes a change to the compensation under Section 3.1(a), then
the amount of compensation shall be determined under the procedures in Section
3.1(b). For purposes of this Section 9.4, "Triggering Event" means the
effectiveness of any statute, rule, regulation, order, decree or regulatory
interpretation (i) prohibiting the Practice or any of the Practice Physicians
from referring patients (whether Medicare, Medicaid or otherwise) for renal
dialysis either directly or indirectly to the Facilities; (ii) prohibiting the
Company, the Practice or any Practice Physician from submitting claims or
receiving payment under the Medicare, Medicaid or any other third party payment
programs for services rendered to patients receiving care at the Facilities;
(iii) determining that the amount or method for determining compensation paid to
the Practice hereunder does not reflect fair market value for the services
provided by the Practice under this Agreement without taking into account the
volume or value of referrals made by the Practice Physicians; or (iv) otherwise
rendering illegal the relationship hereunder between the Company, the Practice
and the Practice Physicians.

          (b) Subject to the provisions of subsection (a) of this Section 9.4,
if any provision of this Agreement is held to be illegal, invalid or
unenforceable under present or future laws in effect during the term of this
Agreement, the legality, validity or enforceability of the remaining provisions
of this Agreement shall not be affected thereby.

      9.5 Headings. The headings of this Agreement are inserted for convenience
only and are not to be considered in construction of its provisions.

      9.6 Entire Agreement. This Agreement constitutes the full contract and
agreement of the parties with respect to its subject matter, superseding all
prior or contemporaneous agreements, either oral or written.

      9.7 Construction of the Agreement and Binding Effect. Notwithstanding the
place where this Agreement may be executed by any of the parties hereto, the
parties expressly agree that all terms and conditions of this Agreement shall be
construed under and governed by the laws of the State of Texas. Venue of any
dispute regarding this Agreement (including any mediation or arbitration) shall
be in Smith County, Texas.

      9.8 Non-Waiver. The failure of either party to exercise any of its rights
under this Agreement for a breach thereof shall not be deemed to be a waiver of
such rights or a waiver of any subsequent breach.

      9.9 Disputes. (a) The parties agree that any dispute arising in connection
with, or relating to, this Agreement or the termination of this Agreement (other
than a dispute related to Sections 3.1(b) or 9.4) shall be subject to resolution
through informal methods. If the parties are unable to resolve such dispute
after thirty days of efforts, then such dispute shall be submitted to mediation
with a singe mediator selected by the parties or, failing the parties' agreement
on a mediator, selected by the American Health Lawyers Association Alternative
Dispute Resolution Service (the "AHLA-ADRS"). The mediation shall be conducted
in accordance with the AHLA-ADRS Rules of Procedure for Mediation. If the
parties are unable to resolve the dispute through mediation, they shall retain
all rights and remedied at applicable law, subject to paragraph (b) below.

          (b) Following the procedures outlined in paragraph (a) above, the
parties agree that any dispute arising in connection with, or relating to, this
Agreement or the termination of this Agreement (other than a dispute related to
Section 3.1(b) and, unless the Company so agrees, a dispute under Article VII),
to the maximum extent allowed by applicable law, shall be subject to arbitration
in accordance with the terms of the AHLA-ADRS Rules of Procedure for Arbitration
(the "ADR Procedures"). A single arbitrator shall be

                                     - 14 -
<PAGE>
chosen mutually by the parties pursuant to the ADR Procedures. Notwithstanding
the foregoing, any party hereto may seek all available preliminary injunctive or
other temporary relief pending the issuance of an arbitration award. The award
of the arbitrator shall contain findings of fact and conclusions of law and
shall be binding and conclusive upon the parties.

      9.10 Third Party Beneficiaries. The Practice and the Practice Physicians
agree that RCG and its affiliates are express and intended third party
beneficiaries of this Agreement.

      9.11 Right of First Refusal to Provide Medical Director Services. If the
Company or any affiliate of the Company seeks to establish any de novo or
satellite dialysis facility within the Territory (as defined in Section 7.1),
then the Practice shall have a right of first refusal, but not the obligation,
to provide medical director services to any such facility. The terms and
provisions governing the provision of such services shall be substantially the
same as the terms and provisions of this Agreement, provided that the
compensation for such additional services shall not be less than $30,000 per
facility. The Company will notify the Practice in writing at least 120 days
prior to opening a de novo or satellite facility. Such notice will specify the
medical director fee proposed for such facility. If the Practice declines such
offer or fails to respond to such offer within the applicable 120-day period,
then the Company will be free to engage another physician or practice to provide
such medical director services on substantially the same terms and conditions as
offered by the Company to the Practice.

                       MEDICAL DIRECTOR PERFORMANCE REVIEW

         The annual evaluation of the RCG Facility and Medical Director is
essential to the mission, "to improve the quality of life and to care for those
patients with chronic and acute renal disease." To achieve this mission, all
associates of the Facility must function collaboratively at the highest possible
level, under the leadership of the Medical Director. The Facility/Medical
Director evaluation is conducted annually by the Chief Medical Officer, to whom
the Medical Director is primarily responsible. This evaluation process must be
understood by Medical Directors, since it is an important component of the RCG
policy of continuous quality improvement.

         The Interpretive Guidelines for ESRD Facilities states "Treatment is
under the general supervision of a Director who is a physician. The Medical
Director is responsible for planning, organizing, conducting and directing the
professional ESRD services and must devote sufficient time to carrying out these
responsibilities." The Nephrologist has the medical skills and must develop
leadership and collaborative management skills to fulfill this mandate as
Medical Director. Teamwork and collegiality are highly valued as the leader of
the ESRD team.

         The Practice shall be eligible for an annual bonus of up to 15% of the
base medical director compensation paid during the year based upon the success
of the Facilities in meeting annual clinical outcomes targets and in achieving
performance objectives for the Facilities and the Practice generally prescribed
by RCG for its dialysis facilities in the region in which the Facilities are
located. Each year the base compensation paid to the practice is allocated
between the Facilities as agreed upon by RCG and the Practice. Then, each
Facility is placed in a quartile based on its evaluation. If a Facility is in
the top quartile, then 100% of 15% of the base compensation allocated to that
Facility is paid to the Practice. If a Facility is in the second quartile, then
66.67% of 15% of the base compensation allocated to that Facility is paid to the
Practice. If a Facility is in the third quartile, then 33.33% of 15% of the base
compensation allocated to that Facility is paid to the Practice. If a Facility
is in the fourth quartile, then nothing is paid to the Practice for that
Facility.

         The evaluation is based on an annually updated point system, authorized
and reviewed by the RCG Medical Advisory Board (MAB). The elements measured and
their weight are as follows:

         -        50 % based on Clinical Indicators of the Facility. The
                  Clinical Indicators are measured monthly and reported
                  quarterly. Measurement is based on the RCG one year rolling
                  average. Tracking the Clinical Indicators and observing trends
                  provides opportunities for quality improvement using the CQI
                  process. The market or regional Quality Management Committee
                  is charged with reviewing the outcomes and performance of each
                  Facility and is available as a resource to the Medical
                  Director.

                  The point system has been weighted to encourage reduction of
                  temporary catheters and placement of AV fistulas. Vascular
                  access is the indicator most influenced by the concerted
                  effort of the Medical Director. The literature shows both
                  mortality and morbidity are reduced with early permanent
                  access placement. Reduction of mortality is the most important
                  outcome, but can only occur with improvement in all care
                  processes that impact patient outcomes (such as URR,
                  nutrition, anemia, etc.).
<PAGE>
         -        30 % based on Medical Director administrative duties. Section
                  5 and 6 of this Handbook describe the administrative duties in
                  greater detail. Guidelines have been prepared for the Medical
                  Directors of both Hemodialysis and Home Therapy Facilities. At
                  the back of each section is a grid, which is designed to
                  assist the Medical Director and the Manager of each Facility
                  in the documentation of the performance of these duties. On a
                  monthly basis, the required tasks should be completed and both
                  the Medical Director and the Manager of each Facility should
                  initial the completion at the bottom of the grid. At a
                  minimum, this will document the compliance of the Medical
                  Director with regulatory requirements by Medicare.

                  The CQI process is a vital part of the quality improvement
                  process of the Facility and the Medical Director is expected
                  to participate in this process. Three levels of participation
                  are provided for but a High level of participation is expected
                  as Medical Directors become knowledgeable and proficient with
                  the CQI process. The Chief Medical Officer (CMO) and his staff
                  are available as resources.

         -        20 % based on patient satisfaction with the Facility. The
                  Patient Satisfaction Survey will be conducted in the spring of
                  each year and the results made available to the Facility and
                  Medical Directors. The Medical Director, as the clinical
                  leader, and the Manager of each Facility, are held responsible
                  for the performance of the staff of the Facility. Although not
                  directly under the control of the Medical Director, he/she is
                  expected to be a positive influence on the staff and their
                  performance in the Facility.

         Completion of the duties should be documented in some manner, in
addition to a check mark on the grid sheet, further described in Section 5.
Common tools of documentation include minutes from meetings, a personal Medical
Director notebook, or dictated notes kept in the Facility. The Manager of each
Facility (or an RCG designee) must concur that the line item on the check list
was completed and initial the monthly grid sheet with the Medical Director. This
indicates that the line item was completed to the satisfaction of both parties.
The grid sheet and related documentation is the property of the Medical
Director. A copy of the grid sheet should be forwarded monthly to the office of
the Associate Medical Officer for monitoring purposes and for use in the annual
Medical Director evaluation. The Medical Director will be held accountable for
meeting facility outcome criteria. Failure to improve outcomes, as measured by
the annual Medical Director evaluation, especially when in the 4th Quartile of
performance, will result in a request for a written explanation to the Chief
Medical Officer.

Combination Hemodialysis & Peritoneal Medical Director

For those physicians who oversee both modalities, each is evaluated using the
above criteria. The overall Clinical Quality is then a composite of these,
weighted to reflect the numbers of patients in each modality.

MEDICAL DIRECTOR ADMINISTRATIVE TASKS (30 %)

The completion of administrative tasks must be documented by the Medical
Director on a monthly basis. It is important that both the Manager of each
Facility and the Medical Director document completion of the required tasks.
Other Medical Director functions including such things as meeting with surgeons
regarding access, goals, attendance at medical meetings and literature review
regarding ESRD issues, etc, should also be noted in this record as well, since
this contributes to a high quality Facility.

Participation in monthly review:

         -        Review staffing & training issues impacting patient outcomes
                  with Manager

         -        Review water quality

         -        Review dialyzer reuse at the Facility

         -        Review monthly lab of patients below quality goals & develop
                  plan

         -        Review trend in hospitalizations, infections

         -        Review temporary catheter usage & trend

         -        Review patient incident reports & trends

         -        Monitor staff physician patient rounding process
<PAGE>
         -        Adequacy of staff physician medical documentation

Participation in CQI process:

         -        The CQI process should be a routine process in the Facility
                  striving to improve its outcomes. As physicians learn this
                  process, Medical Directors are expected to participate at
                  higher levels. In the meantime, Low, Medium and High
                  participation levels may be chosen on the Performance grid,
                  depending on the physician's comfort with the process.

Participation in Professional Staff process:

         -        Participate in the Quarterly Quality conference calls, which
                  have physician CME available.

Annual checklist:

         -        Review and approve Facility Policy and Procedures and make
                  necessary modifications; review and approve clinical
                  protocols. - Review patient satisfaction data annually and in
                  concert with the Manager of the Facility make recommendations
                  for improvement.

         -        Participate with the Manager in the Budget process for the
                  Facility - Participate in Facilities' surveys by regulatory
                  agencies.

Patient Satisfaction Surveys (PSS) (20 %)

The Satisfaction Survey will be conducted in the spring of each year and results
forwarded to each Facility for review and discussion regarding potential areas
of improvement.

                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT is made and entered into effective as of the 3rd day of
November 2003, by and between RENAL CARE GROUP, INC., a Delaware corporation
(the "Company"), and DAVID M. DILL (hereinafter "Employee").

                                   WITNESSETH:

         WHEREAS, Employee is currently Senior Vice President, Finance, and the
Company desires to employ and retain Employee to act as its Executive Vice
President and Chief Financial Officer; and

         WHEREAS, Employee desires to remain an employee of the Company on the
terms and conditions contained in this Agreement; and

         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.

                  The Company employs Employee and Employee accepts employment
with the Company under the terms of this Agreement effective as of November 3,
2003 (the "Effective Date").

         2.       Term.

                  The term of this Agreement shall begin on the Effective Date
and shall continue for an initial term of approximately three years and two
months, ending on December 31, 2006 (the "Initial Period"), subject to earlier
termination by Employee or the Company as hereinafter provided. Unless one party
gives the other notice of non-renewal not less than 60 days prior to the
expiration of the Initial Period or an additional term, this Agreement shall
renew for additional terms of 12 months each, subject to earlier termination as
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 a
base salary at an annual rate of $275,000 from the Effective Date through March
31, 2004 (the "Base Compensation"). Such Base Compensation may be adjusted as
provided herein. The Base Compensation is payable according to the pay periods
of the Company as may be in effect from time to time. Such payments will be
prorated for periods less than a full pay period. The Base Compensation will be
subject to withholding for federal, state and local payroll and all other taxes
or withholdings applicable to Employee. Any increases of the Base Compensation
will be at the discretion of the Company, provided that the Company may not
decrease the then current Base Compensation without the consent of Employee. The
Base Compensation and target percentage for the Annual Bonus (as defined below)
will be reviewed annually by the Compensation Committee of the Company.

                  (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 senior management

<PAGE>

employees of the Company, as such benefits may be determined from time to time
by the Company. Employee may take vacations at times and for periods that are
approved from time to time by the Company's President and Chief Executive
Officer in his reasonable discretion, Employee not accruing any vacation time
for purposes of compensation upon termination of employment. The Company and
Employee acknowledge and agree that vacation time of at least four weeks per
calendar year is expected, but that such amount may be more or less in any
specific. In addition, during the term of this Agreement, the Company will
provide to Employee term life insurance coverage of $1,000,000 on Employee's
life payable to one or more beneficiaries designated by Employee from time to
time.

                  (c)      Annual Bonuses. In addition to the Base Compensation,
Employee will be entitled to an annual bonus (the "Annual Bonus"), with a target
amount equal to 75% of the Base Compensation for such year. The actual amount of
the Annual Bonus paid will be determined based on the Company's and Employee's
achievement of performance goals reasonably established by the Compensation
Committee of the Company and, in the case of performance goals established
specifically for Employee, agreed to by Employee. The Company agrees that the
Company-related performance goals for Employee shall be substantially similar to
those established for other members of senior management.

                  (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 employed as Executive Vice President and Chief
Financial Officer of the Company. As such, Employee will perform such duties and
responsibilities as are typically incident thereto and will perform in a
faithful and competent manner such additional duties as may be reasonably
assigned from time to time by the Company. Throughout the term of this
Agreement, Employee will report to the Chief Executive Officer and President of
the Company. Employee's duties for the Company will be performed on a full-time
basis at the Company's corporate 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 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 will devote all of Employee's business time,
attention, knowledge, and skill solely to the business and interest of the
Company, and the Company will 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
Employee may terminate Employee's employment under this Agreement at any time
for any reason or no reason upon 30 days' 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" means: (i) Employee is convicted of, pleads guilty to, or
confesses to a felony or any crime involving any act of dishonesty,

                                       -2-

<PAGE>

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 material failure by
Employee otherwise substantially to perform his duties with the Company (other
than any such failure resulting from the disability of Employee under Section
5(d)(i)) or the breach of any provision of this Agreement other than Section 6.
If the Company terminates this Agreement for Cause pursuant to the provisions of
(ii), (iii), (iv) or (v) of this subsection (b), then the Company will give
Employee written notice prior to such termination detailing the specific acts,
actions, failures, or events upon which the forecast termination is based.
Employee will have 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 15-day 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)      Termination for Good Reason. Employee may terminate
this Agreement on written notice at any time for "Good Reason". For purposes of
this Agreement, "Good Reason" means: (i) without the express written consent of
Employee, a material diminution of his position, duties, responsibilities and
status with the Company as in effect as of the Effective Date, a change in
Employee's reporting responsibilities, a material reduction of Employee's titles
or offices as in effect on the date of this Agreement, or the removal of
Employee from, or failure to re-elect Employee to, any position referred to in
Section 4 of this Agreement, except in connection with the termination of this
Agreement for Cause; (ii) any reduction of the Base Compensation; (iii) the
requirement that Employee relocate outside of the Nashville, Tennessee
metropolitan area; (iv) the material breach by the Company of any material
provision of this Agreement, which breach continues uncorrected and uncured for
15 days after Employee gives notice of such breach to the Company; or (v) the
termination of this Agreement by written notice from Employee to the Company
during the 30-day period immediately following the first anniversary of a Change
in Control (as defined below).

                  (d)      Involuntary Termination. The employment of Employee
hereunder will be automatically terminated by the death or disability of
Employee as outlined below.

                           (i)      Disability. The Company may terminate this
Agreement at such time as Employee shall have been Disabled (as defined below)
for a continuous period of six months during any continuous 12-month period. For
purposes of this Section 5(d)(i), the term "Disabled" means Employee's inability
to perform the essential functions of his duties, with or without reasonable
accommodation. During Employee's six-month period of Disability, the Company
will continue to pay Employee's Base Compensation (less regular withholdings for
payroll or other taxes and other required or proper items, and less proceeds
from all disability insurance policies or plans provided or made available by
the Company). In the event of a termination of Employee on account of
Disability, the Company will pay Employee's Base Compensation for a period of
six months following the effective date of termination (less regular
withholdings for payroll or other taxes and other required or proper times, and
less proceeds from all disability insurance policies or plans provided or made
available by the Company). In addition, any provisions in the relevant stock
option agreements notwithstanding, all outstanding stock options granted to
Employee by the Company will vest immediately upon termination pursuant to this
Section 5(d)(i).

                           (ii)     Death. If Employee dies during the term of
this Agreement, this Agreement shall terminate and Employee's estate shall
receive the remainder of the Base Compensation

                                       -3-

<PAGE>

set forth in Section 3(a) hereof accrued to the last day of the month in which
death occurs. In addition, any provisions in the relevant stock option
agreements notwithstanding, all outstanding stock options granted to Employee by
the Company will vest immediately upon termination pursuant to this Section
5(d)(i).

                  (e)      Post-Termination Compensation. Except as provided in
Section 5(d) 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 or with Good
Reason. If the Company terminates Employee's employment hereunder without Cause
under Section 5(a) above or if Employee terminates Employee's employment
hereunder with Good Reason under Section 5(c) above or if this Agreement expires
as a result of the Company's giving notice of non-renewal as contemplated by
Section 2 above, then the Company will pay to Employee, after the effective date
of such termination, as Employee's sole and exclusive remedy, (A) an amount
equal to the Base Compensation (as then in effect) plus an amount of Annual
Bonus equal to the target percentage of Base Compensation (as then in effect),
and (B) any unpaid bonus payable for the most recently completed calendar year.
If the Company terminates Employee's employment without Cause or if Employee
terminates Employee's employment hereunder with good reason or if this Agreement
expires as a result of the Company's giving notice of non-renewal, Employee
shall be under no duty to seek or accept other employment; but if he shall do
so, any compensation he shall receive from such other employment will not
diminish the Company's obligation to make payments required to the Employee
hereunder.

                           (ii)     Termination without Good Reason. If Employee
terminates his employment under Section 5(a) above, then the Company's
obligation to pay Employee's Base Compensation will terminate as of the date of
termination.

                           (iii)    Termination for Cause. If the Company
terminates Employee's employment with Cause under Section 5(b) above, then the
Company will pay Employee, after the effective date of such termination, the
Base Compensation (as then in effect) for a period of one month after the
termination date.

                           (iv)     Termination following Change in Control. If,
within twelve (12) months following a Change in Control, either (A) the Company
terminates the employment of Employee hereunder without Cause under Section 5(a)
above or (B) Employee terminates his employment for Good Reason under Section
5(c) above (except for a termination under clause (v) of Section 5(c)), then, in
lieu of any other compensation that may be specified in this Agreement, the
Company will pay Employee an amount equal to (i) the Base Compensation (as then
in effect) plus an amount of Annual Bonus equal to the target percentage of Base
Compensation (as then in effect) multiplied by (ii) three. If Employee
terminates his employment for Good Reason under clause (v) of Section 5(c)
above, then, in lieu of any other compensation that may be specified herein, the
Company will pay Employee an amount equal to (i) the Base Compensation (as then
in effect) plus an amount of Annual Bonus equal to the target percentage of Base
Compensation (as then in effect) multiplied by (ii) two. The Company will make
any payment due under this clause (iv) in a single lump-sum payment not later
than 30 days after termination. If any payment obligation under this Section
5(e) arises, no compensation received from other employment (or otherwise) will
reduce the Company's obligation to make the payment(s) described in this
paragraph.

                  (f)      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 or 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 l3d-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) will 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 a
reorganization, merger, share exchange or consolidation with respect to which
those persons who were the beneficial owners, immediately prior to such
reorganization, merger, share exchange or consolidation, of 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.

         6.       Nondisclosure, Confidentiality; Competition.

                  (a)      Subject to Section 6(f) below, Employee agrees that,
during the term of this Agreement and of Employee's employment by the Company,
and for a period 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 a 75-mile radius of any
renal dialysis center, unit or facility owned or operated by the Company or an
affiliate of the Company. For purposes of this Section, the "business of the
Company or its affiliates" means owning or operating a renal dialysis center,
unit or facility. The parties acknowledge and agree that nothing in this Section
6(a) shall be deemed to restrict any firm of accountants of or with which
Employee becomes an employee, partner, shareholder or otherwise

                                       -5-

<PAGE>

associated or affiliated from rendering accounting services to any business
entity or entities that are competitive with the business of the Company or its
affiliates, so long as Employee does not perform services for any such business
entity and that such entity or entities do not represent more than fifty percent
(50%) of the revenue of such firm in any twelve (12)-month period.

                  (b)      Employee further agrees that, for a period of three
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 Employee. Employee 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 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 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" means owning or operating a renal dialysis
center, unit or facility.

                  (c)      Subject to Section 6(f) below, Employee further
agrees that, for a period of three 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)      Subject to Section 6(f) below, Employee further
agrees that, for a period of three 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)      The Company agrees that the forgoing covenants in
subsections (a), (c) and (d) of this Section 6 shall be null and void as to any
period following termination of Employee's employment if such termination occurs
within 13 months following a Change in Control through either (A) a

                                       -6-

<PAGE>

termination by the Company without Cause under Section 5(a) above or (B) a
resignation by Employee for any reason.

                  (g)      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. The
obligations of Employee to indemnify and hold the Company harmless include any
and all costs of defense of any such claim or threatened claim, including
reasonable attorneys' fees.

         7.       Certain Additional Payments by the Company.

                  (a)      Anything in this Agreement to the contrary
notwithstanding and except as set forth below, if any payment or distribution by
the Company to or for the benefit of Employee (whether paid or payable or
distributed or distributable pursuant to the terms of this Agreement or
otherwise, but determined without regard to any additional payments required
under this Section 7) (a "Payment") would be subject to the excise tax imposed
by Section 4999 of the Code or any interest or penalties are incurred by
Employee with respect to such excise tax (such excise tax, together with any
such interest and penalties, are hereinafter collectively referred to as the
"Excise Tax"), then the Company will make an additional payment (a "Gross-Up
Payment") to Employee in an amount such that after payment by Employee of all
taxes (including any interest or penalties imposed with respect to such taxes),
including, without limitation, any income taxes (and any interest and penalties
imposed with respect thereto) and Excise Tax imposed upon the Gross-Up Payment,
Employee retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Payments.

                  (b)      Subject to the provisions of Section 7(c), all
determinations required to be made under this Section 7, including whether and
when a Gross-Up Payment is required and the amount of such Gross-Up Payment and
the assumptions to be utilized in arriving at such determination, will be made
by Ernst & Young LLP or such other certified public accounting firm as may be
designated by Employee (the "Accounting Firm") which shall provide detailed
supporting calculations both to the Company and Employee within 15 business days
of the receipt of notice from Employee that there has been a Payment, or such
earlier time as is requested by the Company. In the event that the Accounting
Firm is serving as accountant or auditor for the individual, entity or group
effecting the Change in Control, Employee shall appoint another nationally
recognized accounting firm to make the determinations required hereunder (which
accounting firm shall then be referred to as the Accounting Firm hereunder). All
fees and expenses of the Accounting Firm shall be borne solely by the Company.
Any Gross-Up Payment, as determined pursuant to this Section 7, shall be paid by
the Company to Employee within five business days of the receipt of the
Accounting Firm's determination. Any determination by the Accounting Firm shall
be binding upon the Company and Employee. It is possible (due to the uncertainty
in the application of Section 4999 of the Code at the time of the initial
determination by the Accounting Firm hereunder) that Gross-Up Payments will not
have been made by the Company which it is ultimately determined should have been
made ("Underpayment"), consistent with the calculations required to be made
hereunder. Consequently, if the Company exhausts its remedies pursuant to
Section 7(c) and Employee thereafter is required to make a payment of any Excise
Tax, the Accounting Firm shall determine the amount of the Underpayment that has
occurred and the Company will promptly pay any such Underpayment to or for the
benefit of Employee.

                  (c)      Employee will notify the Company in writing of any
claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Gross-Up Payment. Such notification shall be given
as soon as practicable but no later than 10 business days after

                                       -7-

Employee is informed in writing of such claim, and such notification will
apprise the Company of the nature of such claim and the date on which such claim
is requested to be paid. Employee will not pay such claim prior to the
expiration of the 30-day period following the date on which Employee gives such
notice to the Company (or such shorter period ending on the date that any
payment of taxes with respect to such claim is due). If the Company notifies
Employee in writing prior to the expiration of such period that it desires to
contest such claim, Employee will:

                           (i)      Give the Company any information reasonably
requested by the Company relating to such claim,

                           (ii)     Take such action in connection with
contesting such claim as the Company reasonably requests in writing from time to
time, including, without limitation, accepting legal representation with respect
to such claim by an attorney reasonably selected by the Company,

                           (iii)    Cooperate with the Company in good faith in
order effectively to contest such claim, and

                           (iv)     Permit the Company to participate in any
proceedings relating to such claim;

provided, however, that the Company will bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and will indemnify and hold Employee harmless, on an after-tax
basis, for any Excise Tax or income tax (including interest and penalties with
respect thereto) imposed as a result of such representation and payment of costs
and expenses. Without limitation of the foregoing provisions of this Section
7(c), the Company will control all proceedings taken in connection with such
contest and, at its sole option, may pursue or forgo any and all administrative
appeals, proceedings, hearings and conferences with the taxing authority in
respect of such claim and may, at its sole option, either direct Employee to pay
the tax claimed and sue for a refund or contest the claim in any permissible
manner, and Employee agrees to prosecute such contest to a determination before
any administrative tribunal, in a court of initial jurisdiction and in one or
more appellate courts, as the Company may determine; provided, however, that if
the Company directs Employee to pay such claim and sue for a refund, the Company
will advance the amount of such payment to Employee, on an interest-free basis
and will indemnify and hold Employee harmless, on an after-tax basis, from any
Excise Tax or income tax (including interest or penalties with respect thereto)
imposed with respect to such advance or with respect to any imputed income with
respect to such advance; provided, further, that any extension of the statute of
limitations relating to payment of taxes for the taxable year of Employee with
respect to which such contested amount is claimed to be due is limited solely to
such contested amount. Furthermore, the Company's control of the contest will be
limited to issues with respect to which a Gross-Up Payment would be payable
hereunder and Employee will be entitled to settle or contest, as the case may
be, any other issue raised by the Internal Revenue Service or any other taxing
authority.

                  (d)      If, after the receipt by Employee of an amount
advanced by the Company pursuant to Section 7(c), Employee becomes entitled to
receive any refund with respect to such claim, Employee will (subject to the
Company's complying with the requirements of Section 7(c)) promptly pay to the
Company the amount of such refund (together with any interest paid or credited
thereon after taxes applicable thereto). If, after the receipt by Employee of an
amount advanced by the Company pursuant to Section 7(c), a determination is made
that Employee is not entitled to any refund with respect to such claim and the
Company does not notify Employee in writing of its intent to contest such denial
of refund prior to the expiration of thirty (30) days after such determination,
then such advance will be forgiven

                                       -8-

and Employee shall not be required to repay and the amount of such advance will
offset, to the extent thereof, the amount of Gross-Up Payment required to be
paid.

         8.       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 will be in violation of the laws of
any state where applicable, such paragraph, sentence, clause or the combination
of the same will 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 will be fully
enforceable.

         9.       Entire Agreement; Modification.

                  This Agreement constitutes the entire agreement between the
parties and supersedes any and all prior understandings or agreements. Any
changes or additions to this Agreement must be in writing and signed by both
parties. If there is any conflict between the terms of this Agreement and any
stock option agreement or other agreement between Employee and the Company
(including any agreement entered into after the date of this Agreement), then
this Agreement will control unless there is specific reference to superseding
this Agreement in such other agreement or in this Agreement.

         10.      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 are not 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 merges or effects a consolidation or share exchange with or into, or
sells or otherwise transfers 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 and provided, further,
that the provisions of Section 5 remain in full force and effect following such
assignment.

         11.      Notice.

                  Unless otherwise specifically provided, references to notice
periods of a certain number of "days" contained in this Agreement are references
to 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., 2525 West End Avenue, Suite 600,
Nashville, Tennessee 37203, Attention: General Counsel.

         12.      Waiver.

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

         13.      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, will 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 11. The
parties will thereafter attempt in good faith to resolve their differences
within 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 Commercial Arbitration
Rules 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 attorneys' fees incurred in
connection with such dispute. The Company and Employee are parties to an
Indemnification Agreement effective as of August 13, 2002, which the parties
specifically ratify and confirm by this reference.
