To the Stockholders of Renal Care Group, Inc.:
 
     You are cordially invited to attend a special meeting of stockholders (the
"Special Meeting") of Renal Care Group, Inc. ("RCG") to be held on September 27,
1996, at 9:30 a.m., local time, at 2100 West End Avenue, Suite 800, Nashville,
Tennessee, 37203.
 
     At this important meeting, you will be asked to consider proposals to (i)
approve and adopt an Agreement and Plan of Merger (the "Merger Agreement") which
provides for the acquisition of RENALWEST, L.C., an Arizona limited liability
company ("RenalWest"), by means of the merger (the "Merger") of three wholly
owned subsidiaries of RCG into the three corporate members ("Members") of
RenalWest, and the issuance of an aggregate of 2,400,000 shares of RCG's common
stock to the stockholders of the Members upon consummation of the Merger and
(ii) amend the Renal Care Group, Inc. 1996 Stock Option Plan to, among other
things, increase the number of shares available for issuance thereunder (the
"Amendment").
 
     If the proposed Merger is consummated, each outstanding share of common
stock of the Members (excluding shares held by stockholders who perfect their
dissenters' rights) will cease to be outstanding and will be converted into
shares of RCG's common stock and RenalWest will become a wholly owned
second-tier subsidiary of RCG. After the Merger, the former stockholders of the
Members of RenalWest are expected to own approximately 19% of the then issued
and outstanding shares of RCG Common Stock. In addition, certain persons
affiliated with RenalWest will be granted options to purchase an aggregate of
270,000 shares of RCG's common stock.
 
     Enclosed are the (i) Notice of Special Meeting, (ii) Proxy Statement and
(iii) Proxy for the Special Meeting. The Proxy Statement describes in more
detail the terms of the Merger and the Amendment and provides certain financial
and other information pertaining to RCG, RenalWest and the Members. Attached as
Appendices to the Proxy Statement are copies of (i) the Merger Agreement, (ii) a
fairness opinion received by the Board of Directors in connection with the
Merger and (iii) the Option Plan, as amended. Please give this information your
careful attention.
 
     THE BOARD OF DIRECTORS IS UNANIMOUSLY OF THE VIEW THAT THE PROPOSED MERGER
AND THE AMENDMENT ARE IN THE BEST INTERESTS OF RCG AND ITS STOCKHOLDERS, AND
UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR APPROVAL OF THE MERGER
AGREEMENT AND THE ISSUANCE OF RCG'S COMMON STOCK PURSUANT THERETO AND FOR
APPROVAL OF THE AMENDMENT.
 
     We urge you to complete, sign, and date the enclosed Proxy and to return it
promptly in the enclosed envelope, whether or not you plan to attend the Special
Meeting. If you attend the Special Meeting, you may revoke your Proxy and vote
in person if you wish.
 
     We look forward to seeing you at the Special Meeting.
 
                                          Sincerely yours,

of the Effective Time (as defined herein), each of the Merger Corps will be
merged into one of the Members and each share of Member Common Stock issued and
outstanding immediately prior to the Merger will be converted into shares of RCG
 
                                        4

Common Stock. An aggregate of 2,400,000 shares of RCG Common Stock will be
issued to the Owners upon consummation of the Merger. The number of shares to be
issued to the Owners was determined based upon the negotiation of an aggregate
purchase price of $72,000,000 divided by $30.00, the average trading price of
the RCG Common Stock for the twenty trading days prior to the date of execution
of the Merger Agreement. The following table shows the aggregate dollar value of
the Merger at various assumed trading prices of the RCG Common Stock:

     In the event RCG changes the number of shares of RCG Common Stock issued
and outstanding prior to the Effective Time as a result of a stock split, stock
dividend, combination of shares or similar recapitalization with respect to such
stock and the record date therefor or, if there is no record date, the effective
date thereof, shall be prior to the Effective Time, then the number of shares to
be issued in the Merger shall be adjusted to appropriately and proportionately
adjust the number of shares of RCG Common Stock into which the shares of Member
Common Stock will be converted.
 
     The Merger Agreement provides that at closing of the Merger, RCG shall
grant options to purchase an aggregate of 270,000 Shares of RCG Common Stock to
certain persons affiliated with the RenalWest Parties. Such options shall be
nonqualified stock options for tax purposes, shall have an exercise price equal
to the closing price of RCG Common Stock on the Nasdaq NMS on the closing date
and shall vest over a five-year period. The additional terms of said options
shall be commensurate with similar stock options granted generally by RCG to
similarly situated employees and affiliates of RCG.
 
  Recommendation of RCG's Board of Directors
 
     RCG's Board of Directors is unanimously of the view that the Merger is in
the best interests of RCG and its stockholders. RCG's Board of Directors has
recommended that RCG's stockholders vote FOR the Merger. The Board of Directors'
recommendation is based upon a number of factors discussed in this Proxy
Statement. See "The Merger -- Reasons for the Merger."
 
  Opinion of Financial Advisor
 
     Equitable Securities Corporation ("Equitable") has acted as financial
advisor to RCG in connection with the Merger and has delivered a written
opinion, dated the date of this Proxy Statement, to the Board of Directors of
RCG to the effect that, as of the date of such opinion and based upon and
subject to certain matters stated therein, the consideration to be received by
RCG in exchange for the shares of RCG Common Stock to be issued in the Merger
was fair, from a financial point of view, to RCG and its stockholders. A copy of
such opinion is attached as Appendix B to this Proxy Statement and should be
read carefully in its entirety. See "The Merger -- Opinion of Financial
Advisor."
 
  Fractional Shares
 
     No fractional shares of RCG Common Stock will be issued in the Merger. Any
fractional share interest which an Owner would otherwise be entitled to receive
shall be rounded up to the nearest whole share if such fraction is .5 or greater
and shall be rounded down to the nearest whole share if such fraction is less
than .5. See "The Merger -- Issuance of Shares in the Merger."

  Effective Time of the Merger
 
     If the Merger is approved by the requisite vote of RCG stockholders and the
other conditions of the Merger are satisfied or waived, the Merger will be
consummated and become effective on the date and at the time the Articles of
Merger become effective with the Secretary of State of the State of Arizona (the
"Effective Time"). Assuming all other conditions of the Merger are satisfied or
waived, the Merger is expected to become effective promptly after obtaining the
necessary approval of RCG stockholders. See "The Merger -- Effective Time of the
Merger."
 
  Operations after the Merger
 
     Following the Merger, RenalWest will be operated as a wholly owned
second-tier subsidiary of RCG and will retain its status as a limited liability
company governed by the laws of the State of Arizona. The Merger Agreement
provides that the main office of RenalWest in Mesa, Arizona will serve as the
executive headquarters of RCG's southwest region, which will include the
existing operations of the RenalWest Parties in Arizona plus all centers newly
developed or acquired in the states of Arizona, New Mexico, Colorado, Utah,
Nevada and California (the "Southwest Region"). John Greksa, the current Chief
Executive Officer of RenalWest, will serve as the Chief Operating Officer of the
Southwest Region while he is employed with RCG. The foregoing covenant expires
upon the later to occur of the fifth anniversary of the closing date or the date
on which Sam A. Brooks, Jr. ceases to serve as the Chief Executive Officer of
RCG.
 
     The Merger Agreement provides that RenalWest and each affiliated physician
practice that has a physician member or employee involved with the use,
operation of or referral of patients to RenalWest's dialysis facilities (the
"Practices"), shall enter into Medical Director Agreements at Closing under
which the Practices shall provide medical director services to RenalWest for the
dialysis facilities operated by RenalWest. Such Medical Director Agreements
shall have an initial term of serve (7) years with renewal terms for additional
three year periods and shall provide for (i) an aggregate annual fee to be paid
by RCG to the Practices of $840,000 (subject to agreed upon modifications) to be
divided among the Practices at their discretion, (ii) certain restrictive
covenants, including but not limited to a covenant not to compete with a
duration of the term of the Medical Director Agreement and three (3) years after
termination of the Medical Director Agreement, and (iii) other customary terms
and conditions.
 
  Interests of Certain Persons in the Merger
 
     Pursuant to the Merger Agreement, RCG shall at the Closing increase the
number of members of its Board of Directors by one and add an individual
specified by the RenalWest Parties as a director, the identity of whom is
subject to the reasonable approval of RCG, to serve an initial term ending on
the date of RCG's 1999 Annual Meeting of its stockholders. Further, RCG's
management will recommend to its stockholders at such 1999 Annual Meeting that
such designee, or such other designee reasonably approved by RCG, serve for an
additional three (3) year term as a member of the Board of Directors of RCG. In
addition, RCG will name a physician specified by the RenalWest Parties to RCG's
Medical Advisory Board, the identity of whom is subject to the reasonable
approval of RCG.
 
  Conditions of Merger; Termination
 
     Consummation of the Merger is conditioned upon the fulfillment or waiver of
certain conditions set forth in the Merger Agreement, including, among other
matters: (i) approval of the Merger by RCG's stockholders; (ii) receipt of a
letter from Ernst & Young LLP to the effect that the Merger may be accounted for
under the pooling-of-interests basis of accounting; (iii) the continued accuracy
of all representations and warranties made in the Merger Agreement, (iv)
obtaining all necessary licenses, consents and permits, (v) the absence of any
material adverse change in the business, assets, liabilities or conditions of
RCG or the RenalWest Companies, (vi) the requisite consent of those stockholders
of RCG who presently have registration rights for the grant of the registration
rights to the Owners, and (vii) no Owner shall have exercised dissenter's
rights. The Merger Agreement may be terminated (i) by mutual written consent of
RCG and the RenalWest Parties, (ii) by either RCG or the RenalWest Parties if
their conditions to the Merger have not been satisfied on or
 
                                        6
<PAGE>   10
 
before October 31, 1996 (provided the satisfaction of such conditions has not
been frustrated or made impossible by the terminating party), and (iii) by RCG
or RenalWest if the Merger has not been completed by November 30, 1996. See "The
Merger -- Conditions to Consummation of the Merger" and "-- Amendments;
Termination."
 
  Accounting Treatment
 
     It is anticipated that the Merger will qualify as a "pooling of interests"
for financial reporting purposes. It is a condition to the obligation of RCG to
consummate the Merger that it shall have received from Ernst & Young LLP a
letter as of the Closing Date to the effect that the Merger may be accounted for
as a pooling of interests by RCG for financial reporting purposes.
 
  Registration Rights Agreement
 
     Under the Merger Agreement, RCG is obligated to undertake reasonable
commercial efforts to file by November 30, 1996 a registration statement under
the Securities Act ("Secondary Offering"), pursuant to which the Owners may
sell, to the extent permissible under the "pooling of interests" rules, up to
forty percent (40%) of their shares of RCG Common Stock. If RCG has not caused
the Secondary Offering to become effective prior to February 7, 1997, then
Owners holding twenty percent (20%) of the shares of RCG Common Stock issued in
the Merger have the right to require RCG to file a registration statement under
the Securities Act for an offering of up to twenty percent (20%) of the RCG
Common Stock originally held by each Owner making such request. In addition, in
the event RCG proposes to register under the Securities Act any RCG Common Stock
for its own account or for the account of others at any time prior to the second
anniversary of the date the shares of RCG Common Stock are issued to the Owners
in the Merger, subject to certain exceptions, the Owners have the right to
require RCG to include up to forty percent (40%) of their shares of RCG Common
Stock in such registration.
 
THE OPTION PLAN
 
     The Option Plan was approved by the sole stockholder of RCG on January 15,
1996. The proposed Amendment to the Option Plan would (i) increase the number of
shares of RCG Common Stock reserved for issuance under the Option Plan from
488,448 shares to 1,000,000 shares and (ii) effect certain technical changes in
light of recent amendments to the rules of the Commission promulgated under
Section 16 of the Exchange Act. A primary reason additional shares are needed
under the Option Plan is to enable RCG to grant options to key employees who
have been or will be employed by RCG in connection with its acquisitions.
Approval of the Amendment by the stockholders of RCG is required pursuant to the
provisions of the Option Plan and the rules of the NASD. In addition,
stockholder approval of the Option Plan is being sought in order to preserve
RCG's federal income tax deduction for compensation that may be earned under the
Option Plan, in accordance with the requirements of the Omnibus Budget
Reconciliation Act of 1993 ("OBRA") and Section 162(m) of the Internal Revenue
Code ("Code"). While no RCG executive's annual compensation has ever approached
$1.0 million, the Board of Directors of RCG has determined to seek stockholder
approval of the Option Plan since it may provide performance based compensation
to senior executives.

     STOCKHOLDERS ARE ADVISED TO OBTAIN CURRENT MARKET QUOTATIONS FOR RCG COMMON
STOCK.  No assurance can be given as to the market price of RCG Common Stock at
the Effective Time or at any other time. As of August 26, 1996, there were
approximately 1,800 beneficial holders of RCG Common Stock.
 
     There is no established public trading market for the Member Common Stock.
As of August 26, 1996, there were approximately 28 holders of record of Member
Common Stock.
 
DIVIDEND POLICY
 
     RCG has never paid any cash dividends on its capital stock. RCG currently
anticipates that all of its earnings will be retained to finance the growth and
development of its business and, therefore, does not anticipate that any cash
dividends will be declared or paid on the RCG Common Stock in the foreseeable
future. Any future declarations of dividends will be subject to the discretion
of RCG's Board of Directors and its review of operations, financial condition,
capital requirements and surplus, contractual restrictions to pay such dividends
and other factors it deems relevant.
 
     RenalWest has from time to time made cash distributions to its Members in
an amount approximating the taxable income of RenalWest. The Members, in turn,
have paid cash dividends to the stockholders of the Members. Under the terms of
the Merger Agreement, the income of RenalWest earned prior to the closing is to
be distributed to the Members in a manner consistent with past practices, and
the Members will distribute such income to the Owners.
 
COMPARATIVE PER SHARE INFORMATION
 
     The following summary presents selected comparative per share information
(i) on a pro forma combined basis for RCG and its subsidiaries for the year
ended December 31, 1995 and the six months ended June 30, 1996 and (ii) on a pro
forma combined basis giving effect to the Merger of RenalWest on a
pooling-of-interest basis for the same periods.
 
     RCG has not paid cash dividends since inception. RenalWest paid cash
dividends to members each year based on the amount of cash available and such
amounts were $4,031,000, $5,094,000 and $2,597,000 for the years ended December
31, 1994 and 1995 and the six months ended June 30, 1996, respectively. It is
anticipated that RCG will retain all earnings for use in the expansion of the
business and therefore does not anticipate paying any cash dividends in the
foreseeable future.
 
     The information shown below is not necessarily indicative of the combined
results of operations or combined financial position that would have resulted
had the Merger been consummated at the beginning of the periods indicated, nor
is it necessarily indicative of the combined results of operations in the future

                              GENERAL INFORMATION
 
THE SPECIAL MEETING
 
     This Proxy Statement is being furnished by RCG to its stockholders in
connection with the solicitation of proxies by the Board of Directors of RCG
from holders of the outstanding shares of RCG Common Stock for use at the
Special Meeting to be held at 2100 West End Avenue, Suite 800, Nashville,
Tennessee 37203, at 9:30 a.m., local time, on September 27, 1996, and at any
adjournments and postponements thereof, to (i) consider and vote upon the
Merger, (ii) consider and vote upon the Amendment to the Option Plan, and (iii)
to transact such other business incidental to the conduct of the Special Meeting
as may properly come before the Special Meeting.
 
     The Merger Agreement provides for the merger of the Merger Corps with and
into the Members, pursuant to which RenalWest will become a wholly owned
second-tier subsidiary of RCG and will continue as a limited liability company
governed by the laws of the State of Arizona. At the Effective Time, each share
of issued and outstanding Member Common Stock shall cease to be outstanding and
shall be converted into RCG Common Stock. An aggregate of 2,400,000 shares of
RCG Common Stock will be issued upon consummation of the Merger. If the Merger
is approved at the Special Meeting, all required consents and approvals are
obtained, and all of the other conditions to the obligations of the parties to
consummate the Merger are either satisfied or waived, the Merger will be
consummated. See "The Merger -- Issuance of Shares in the Merger" and
"-- Effective Time of the Merger."
 
     The proposed Amendment to the Option Plan would (i) increase the number of
shares of RCG Common Stock reserved under the Option Plan from 488,448 shares to
1,000,000 shares and (ii) effect certain technical changes in light of recent
amendments to the rules of the Commission promulgated under Section 16 of the
Exchange Act. Stockholder approval of the Option Plan is being sought in order
to satisfy NASD requirements and preserve RCG's federal income tax deduction for
compensation that may be earned under the Option Plan, in accordance with the
requirements of the Omnibus Budget Reconciliation Act of 1993 ("OBRA") and
Section 162(m) of the Internal Revenue Code ("Code").
 
RECORD DATE AND QUORUM
 
     RCG's Board of Directors has fixed the close of business on August 26,
1996, as the record date for determining RCG stockholders entitled to receive
notice of and to vote at the Special Meeting (the "Record Date"). Only holders
of record of RCG Common Stock as of the Record Date are entitled to vote at the
Special Meeting. At the close of business on the Record Date, there were
10,146,136 shares of RCG Common Stock issued and outstanding and held by
approximately 1,800 beneficial holders. Holders of RCG Common Stock are entitled
to one vote on each matter considered and voted on at the Special Meeting for
each share of RCG Common Stock held of record at the close of business on the
Record Date. The presence, in person or by properly executed proxy, of the
holders of a majority of the outstanding shares of RCG Common Stock entitled to
vote at the Special Meeting is necessary to constitute a quorum at the Special
Meeting. Abstentions and "broker non-votes" (which occur when shares held by
brokers or nominees for beneficial owners are voted on some matters but not on
others) will be counted as shares present for purposes of determining the
presence of a quorum. Broker non-votes will not be counted as votes cast for
purposes of determining whether a proposal has received sufficient votes for
adoption, and as a result will have no effect on the outcome of the vote on the
Proposals. For purposes of determining whether a Proposal has received
sufficient votes for adoption, abstentions will be counted as votes cast and, as
a result, an abstention will have the effect of a vote against the Proposals.
 
SOLICITATION AND REVOCABILITY OF PROXIES
 
     The enclosed proxies are solicited by RCG's Board of Directors. Shares of
RCG Common Stock represented by properly executed proxies, if such proxies are
received in time and are not revoked, will be voted in accordance with the
instructions indicated on the proxies. IF NO INSTRUCTIONS ARE INDICATED, SUCH
 
                                       11
<PAGE>   15
 
PROXIES WILL BE VOTED FOR APPROVAL OF THE PROPOSALS AND AS DETERMINED BY THE
PROXIES AS TO ANY OTHER MATTER INCIDENTAL TO THE CONDUCT OF THE SPECIAL MEETING
THAT MAY PROPERLY COME BEFORE THE SPECIAL MEETING.
 
     An RCG stockholder who has given a proxy may revoke it at any time prior to
its exercise at the Special Meeting by (i) giving written notice of revocation
to the Secretary of RCG, (ii) properly submitting to RCG a duly executed proxy
bearing a later date, or (iii) attending and voting in person at the Special
Meeting. All written notices of revocation and other communications with respect
to revocation of proxies should be addressed to RCG as follows: Renal Care
Group, Inc., 2100 West End Avenue, Suite 800, Nashville, Tennessee 37203,
Attention: Ronald Hinds, Secretary. A proxy appointment will not be revoked by
death or supervening incapacity of the stockholder executing the proxy unless,
before the shares are voted, notice of such death or incapacity is filed with
RCG's Corporate Secretary or other person responsible for tabulating votes on
behalf of RCG.
 
     Any expense of soliciting proxies for the Special Meeting will be paid for
by RCG. RCG will be contacting brokers, dealers, banks or voting trustees or
their nominees who can be identified as record holders of RCG Common Stock. Such
holders, after inquiry by RCG, will provide information concerning the quantity
of proxy and other materials needed to supply such materials to beneficial
owners, and RCG will reimburse them for the expense of mailing the proxy
materials to such persons. RCG does not anticipate retaining a firm to assist in
soliciting proxies for the Special Meeting.
 
VOTE REQUIRED
 
     Approval of the Merger by the stockholders is not required by state law,
but is required pursuant to the rules of the National Association of Securities
Dealers, Inc. ("NASD"). Such approval is being sought solely to comply with such
rules of the NASD. Approval of the Amendment is required by the terms of the
Option Plan as currently in effect and by the rules of the NASD. Approval of
each of the Proposals by the stockholders of RCG requires the presence, in
person or by proxy, of the holders of a majority of all shares entitled to vote
and the affirmative vote of the holders of a majority of the shares present, in
person or by proxy, and entitled to vote on each Proposal. Each share of RCG
Common Stock is entitled to one vote on each matter that comes before the RCG
Special Meeting. As of the RCG Record Date, there were outstanding and entitled
to vote 10,146,136 shares of RCG Common Stock. Accordingly, approval of each
Proposal will require the presence, in person or by proxy, of holders
representing a minimum of 5,073,069 shares of RCG Common Stock and the
affirmative vote, in person or by proxy, of a minimum of 2,536,535 shares of RCG
Common Stock.
 
     If fewer shares are voted in favor of a Proposal than required for its
approval, it is expected that the Special Meeting will be postponed or adjourned
with respect to such Proposal for the purpose of allowing additional time for
obtaining additional proxies or votes. At any subsequent reconvening of the
Special Meeting, all proxies will be voted on the matter(s) to be considered at
the reconvened Special Meeting in the same manner as such proxies would have
been voted on the matter(s) at the original convening of the Special Meeting
(except for any proxies which have theretofore effectively been revoked or
changed), notwithstanding that they may have been effectively voted on the same
or any other matter at a previous meeting. Any such adjournment will require the
affirmative vote of a majority of the shares present at the session of the
Special Meeting to be adjourned. A proxy granting authority to vote upon such
other business incidental to the conduct of the Special Meeting as may properly
come before the Special Meeting will constitute authority to vote in favor of
one or more adjournments of the Special Meeting.
 
     As of the Record Date, the executive officers and directors of RCG
beneficially owned 1,692,231 shares of RCG Common Stock. The executive officers
and directors of RCG have indicated that they intend to vote such shares in
favor of the Proposals. See "-- The Special Meeting," "-- Record Date and
Quorum" and "Ownership of Equity Securities."
 
RECOMMENDATIONS OF RCG'S BOARD
 
     For the reasons described in this Proxy Statement, RCG's Board has approved
the Merger, is unanimously of the view that the Merger is in the best interests
of RCG and its stockholders, and recommends
 
                                       12
<PAGE>   16
 
that RCG stockholders vote FOR approval of the Merger. RCG's Board has also
approved the Amendment and recommends that RCG stockholders vote FOR approval of
the Amendment.
 
                                   PROPOSAL I
 
                                   THE MERGER
 
     The following information describes certain information pertaining to the
Merger. This description does not purport to be complete and is qualified in its
entirety by reference to the Appendices hereto, including the Merger Agreement,
a copy of which is set forth in Appendix A to this Proxy Statement and is
incorporated herein by reference. All stockholders are urged to read the
Appendices in their entirety.
 
GENERAL
 
     Holders of RCG Common Stock are being asked to consider the Merger. The
Merger Agreement provides that the Merger Corps, wholly owned subsidiaries of
RCG, shall merge with and into the Members. The Members shall be the surviving
corporations of the Merger and as a result RenalWest shall become a wholly owned
second-tier subsidiary of RCG and shall continue as a limited liability company
governed by the laws of the State of Arizona. At the time the Merger becomes
effective, each share of issued and outstanding Member Common Stock shall cease
to be outstanding and shall be converted into shares of RCG Common Stock. If the
Merger is approved at the Special Meeting, all required governmental and other
consents and approvals are obtained, and all other conditions to the obligations
of the parties to consummate the Merger are either satisfied or waived, the
Merger will be consummated. A copy of the Merger Agreement is set forth in
Appendix A of this Proxy Statement.
 
BACKGROUND OF THE MERGER
 
     On January 9, 1995, representatives of several privately-owned dialysis
companies met to pursue the concept of combining their respective companies
together in a roll-up transaction. These representatives included, among others,
the Founding Companies of RCG, and representatives of RenalWest. Subsequent
meetings of these companies were held during early 1995, that were attended by
representatives of RenalWest, but RenalWest decided not to participate in the
RCG roll-up transaction. The RCG roll-up transaction proceeded during the latter
part of 1995 and on February 12, 1996, RCG's rollup and initial public offering
were completed. Thereafter Sam A. Brooks, President of RCG, met with several
Board members of RenalWest in Mesa, Arizona, to discuss a possible merger
between RenalWest and RCG. Various telephone conversations ensued between
executive officers of the two companies in which the financial terms of the
potential transaction were discussed, but no terms were agreed upon. On February
22 and 23, Mr. Brooks and Ronald Hinds, Chief Financial Officer of RCG, met with
RenalWest Board members and executive officers at the company's executive
headquarters in Mesa, Arizona to discuss further a possible merger and to obtain
additional financial, operational, and other information relating to RenalWest.
 
     At a regular meeting on February 27, 1996 the RCG Board of Directors
discussed a potential merger transaction with RenalWest. Discussions continued
throughout February and early March, and on March 15, 1996, RCG submitted a
draft letter of intent to RenalWest for its review. Discussions continued but on
March 22, 1996, progress toward a merger stopped when the parties failed to
agree on certain terms. Further conversations were held after this date through
April 9, but no meaningful resolutions of issues occurred during these
discussions. Dr. Harry Jacobson, the Chairman of RCG, called Dr. Kenneth
Johnson, the Chairman of RenalWest, to resume potential merger talks and on May
14, 1996, a draft letter of intent was delivered to RenalWest. The proposed
transaction was discussed and approved by the RCG Board of Directors on June 4,
1996. On June 11, 1996 Dr. Jacobson, Messrs. Brooks and Hinds, and counsel for
RCG, met with the Board members, executives, and counsel for RenalWest in Mesa,
Arizona and discussed the proposed merger arrangements. On June 20, 1996 a
letter of intent, executed by RCG, and approved by the RCG Board of Directors,
was delivered to RenalWest. On August 7, 1996, a definitive merger agreement was
signed by all parties.

REASONS FOR THE MERGER
 
     RCG.  In reaching its decision to approve the Merger Agreement and the
transactions contemplated thereby, the Board of Directors of RCG consulted with
its management team and advisors and independently considered a number of
factors. In view of the variety of factors considered in its evaluation of the
merger, the RCG Board of Directors did not find it practicable to, and did not,
quantify or otherwise attempt to assign relative weights to the specific factors
considered in reaching its determination. Factors considered include the
following:
 
          (i) RCG would obtain a presence in the Southwest from which it can
     acquire and operate additional nephrology businesses in the Western part of
     the United States.
 
          (ii) The merger provides RCG an opportunity to combine with a company
     with a large number of quality, well-managed dialysis centers and hospital
     contracts.
 
          (iii) The opportunities for economies of scale and operating
     efficiencies that should result from the Merger including integration of
     information systems, support functions, and greater purchasing power of the
     two companies.
 
          (iv) RenalWest's significant market position and competitive strength
     in metropolitan Phoenix and the state of Arizona and the favorable
     demographics that exist in its marketplace.
 
          (v) The Merger should better position RCG to deal with Medicare
     capitation which may face the industry in the future.
 
          (vi) RenalWest's business, management team, operational prospects, and
     managed care experience.
 
          (vii) The Merger should enhance RCG's future relationships with
     managed care plans because of broader geographic coverage.
 
          (viii) Based on the relative earnings of both companies and the
     exchange ratio, RCG believes that the Merger will be immediately accretive
     to its current stockholders, and more so in the future assuming certain
     synergies are achieved.
 
          (ix) The condition to the Merger Agreement that the Merger will be
     accounted for under the pooling-of-interests method.
 
          (x) The market capitalization of the combined company will be
     considerably larger than RCG's current market capitalization, which should
     ultimately provide RCG's stockholders with enhanced liquidity.
 
     In addition to the perceived benefits of the proposed Merger, RCG's Board
also considered certain risks, including the risk that RCG would not
successfully integrate the operations of the two businesses in order to
recognize potential cost savings and enhance future earnings prospects. Although
there can be no assurance that such adverse consequences would not occur, RCG's
Board, after consideration, believed that the potential benefits outweighed the
potential risks of the Merger. RCG's Board also considered that after the
proposed transaction the Owners would hold approximately 19% of the outstanding
shares of the Common Stock of RCG. RCG's Board concluded that the significant
post-transaction ownership position of the Owners should not prevent RCG from
proceeding with the transaction.
 
     FOR THE FOREGOING REASONS, AMONG OTHERS, RCG'S BOARD UNANIMOUSLY RECOMMENDS
THAT YOU VOTE FOR THE MERGER.
 
     The RenalWest Parties.  The Boards of Directors of the Members, after
consideration of relevant business, financial, legal and market factors,
including the compatibility of the operations and management of RCG and
RenalWest, and the financial condition and results of operations of RenalWest
and RCG, has concluded that the Merger is in the best interests of the Members
and its stockholders. In reaching their
 
                                       14
<PAGE>   18
 
decision to enter into the Merger Agreement, the Boards of Directors considered
a number of factors, including, without limitation and without assigning
relative weights thereto, the following:
 
          (i) the terms and conditions of the proposed Merger, including the
     value of the consideration to be received by the Owners, the fact that as
     holders of RCG Common Stock, the Owners will have more liquidity, and the
     fact that the Merger is expected to be treated as a tax-free
     reorganization;
 
          (ii) the opportunity for the Owners to continue to share in the
     potential for long-term growth of RenalWest through the ownership of RCG
     Common Stock following the Merger;
 
          (iii) the business reputation and capabilities of RCG and its
     management, the financial strength, prospects, market position and
     strategic objectives of RCG and the historical performance of RCG Common
     Stock; and
 
          (iv) the perceived strengths of RCG and RenalWest combined and the
     belief that RCG and RenalWest are strategically complementary.
 
     The Boards of Directors of the Members also considered certain risks of the
Merger, including the risk that RCG Common Stock has been publicly traded for a
relatively short period of time and that the trading market for such stock has
experienced and may continue to experience some price volatility.
 
ISSUANCE OF SHARES IN THE MERGER
 
     Subject to the terms and conditions set forth in the Merger Agreement, as
of the Effective Time (as defined herein), each of the Merger Corps will be
merged into one of the Members and each share of Members' Common Stock issued
and outstanding (excluding treasury shares) immediately prior to the Merger will
be converted into shares of RCG Common Stock. An aggregate of 2,400,000 shares
of RCG Common Stock will be issued upon consummation of the Merger. The number
of shares to be issued to the former stockholders of the Members was determined
based upon the negotiation of an aggregate purchase price of $72,000,000 divided
by $30.00, the average trading price of the RCG Common Stock for the twenty
trading days prior to the date of execution of the Merger Agreement. The
following table shows the aggregate dollar value of the Merger at various
assumed trading prices of the RCG Common Stock:

      40.00               96,000,000
</TABLE>
 
     In the event RCG changes the number of shares of RCG Common Stock issued
and outstanding prior to the Effective Time as a result of a stock split, stock
dividend, combination of shares or similar recapitalization with respect to such
stock and the record date therefor or, if there is no record date, the effective
date thereof, shall be prior to the Effective Time, then the number of shares to
be issued in the Merger shall be adjusted to appropriately and proportionately
adjust the number of shares of RCG Common Stock into which the shares of Member
Common Stock will be converted.
 
     The Merger Agreement provides that at closing of the Merger, RCG shall
grant options to purchase an aggregate of 270,000 Shares of RCG Common Stock to
certain persons affiliated with the RenalWest Parties. Such options shall be
nonqualified stock options for tax purposes, shall have an exercise price equal
to the closing price of RCG Common Stock on Nasdaq NMS on the closing date and
shall vest over a five-year period. The additional terms of said options shall
be commensurate with similar stock options granted generally by RCG to similarly
situated employees and affiliates of RCG.

OPINION OF FINANCIAL ADVISOR
 
     Equitable Securities Corporation ("Equitable") has provided its oral
opinion to the RCG Board, which is confirmed in a written opinion dated the date
of this Proxy Statement, to the effect that, as of such dates, the
consideration, taken as a whole, to be paid by RCG in the Merger is fair to RCG
and its stockholders from a financial point of view. No limitations were imposed
by the RCG Board with respect to the investigations made of the procedures
followed by Equitable in rendering its opinion. Equitable's opinion was
delivered for the information of the RCG Board and is not a recommendation to
any RCG stockholder as to how such stockholder should vote at the RCG Special
Meeting or any other meeting of RCG stockholders called to consider matters
relating to the Merger.
 
     In arriving at its opinion, Equitable reviewed certain publicly available
business and financial information relating to RCG, certain non-public
information relating to RenalWest, and reviewed the Merger Agreement. Equitable
also reviewed certain other information, including financial forecasts provided
to it by RCG and RenalWest, and met with RCG's and RenalWest's management to
discuss the businesses and prospects of RCG and RenalWest.
 
     Equitable also considered certain financial and stock market data of RCG
and compared that data with similar data for other publicly held companies in
businesses similar to those of RCG, as well as the financial terms of certain
other business combinations and other transactions which have recently been
effected and have considered the financial effects of the Merger on RCG. In
addition, Equitable considered such other information, financial studies,
analyses and investigations and financial, economic and market criteria which it
deemed relevant.
 
     In connection with its review, Equitable did not assume any responsibility
for independent verification of any of the foregoing information and relied on
its being complete and accurate in all material respects. With respect to the
financial forecasts (including without limitation projected operational benefits
and cost savings arising from the Merger), Equitable assumed that they have been
reasonably prepared on bases reflecting the best currently available estimates
and judgments of RenalWest's and RCG's management as to the future financial
performance of RenalWest and RCG. Equitable expressed no view as to such
forecasts or the assumptions on which they are based and there cannot be any
assurance that actual results of RenalWest or RCG will not differ materially
from those reflected in the forecasts. In addition, Equitable did not make an
independent evaluation or appraisal of the assets or liabilities (contingent or
otherwise) of RenalWest or RCG, nor was Equitable furnished with any such
evaluations or appraisals.
 
     The full text of the written opinion of Equitable, dated the date hereof,
which sets forth the assumptions made, procedures followed, matters considered,
limitation on and the scope of the review by Equitable in rendering its opinion,
is attached hereto as Appendix B. RCG stockholders are urged to read Equitable's
opinion in its entirety. The summary of the opinion of Equitable is qualified in
its entirety by reference to the full text of such opinion.
 
     The generally accepted financial analyses Equitable used in reaching its
opinion which it discussed with the RCG Board of Directors included (i)
comparable acquisitions analysis, which consisted of reviewing operating
statistics and purchase price information with respect to selected acquisitions
of businesses similar to those of RenalWest's, (ii) trading analysis of
publicly-traded companies which Equitable considered comparable to the
businesses of RenalWest, (iii) discounted cash flow ("DCF") analysis, which
consisted of discounting to present value the projected cash flows and terminal
values of RenalWest and (iv) an analysis of the pro forma effect of the Merger
on RCG's earnings per share. The material portions of these analyses are
summarized below.
 
  Comparable Acquisitions Analysis
 
     Equitable reviewed acquisitions of companies in the dialysis industry over
the past two years, specifically the acquisition of Caremark Nephrology by Total
Renal Care, the acquisition of REN Corporation -- USA ("REN") by Gambro AB, and
the pending acquisition of W.R. Grace's National Medical Care ("NMC") by
Fresenius AG. For the comparable transactions, Equitable determined the
relationship between the equity
 
                                       16
<PAGE>   20
 
purchase price and net income and between the enterprise value (the equity
purchase price plus debt minus cash and cash equivalents) and revenue and
earnings before interest, taxes, depreciation and amortization ("EBITDA").
Equitable then derived an average of these multiples of net income (16.8x),
revenue (1.4x) and EBITDA (8.6x) and applied these multiples to the financial
data for RenalWest for fiscal year 1996. The reference range of equity value
derived from this analysis was from approximately $46.1 million to approximately
$85.4 million.
 
  Comparable Company Analysis
 
     Equitable reviewed certain financial results of selected public companies
in the dialysis industry deemed to be comparable to RenalWest. Using publicly
available financial and stock price data, Equitable determined the relationship
for these comparable companies between enterprise value (equity value plus debt
minus cash and cash equivalents) and EBITDA. Equitable also compared equity
values as multiples of calendarized projected net income in 1996 and 1997.
Equitable then derived an average of these multiples of EBITDA (20.3x) and
estimated net income for calendar 1996 (35.4x) and net income for calendar 1997
(27.2x). The reference range of enterprise value and equity value derived from
this analysis ranged from approximately $72.1 million to approximately $124.9
million. The comparable companies examined by Equitable included RCG, Rental
Treatment Centers, Inc., Total Renal Care Holdings, Inc., and Vivra.
 
     No company, transaction or business used in the comparable acquisitions,
and comparable company analyses is identical to RenalWest or the Merger.
Accordingly, an analysis of the results of the foregoing is not entirely
mathematical; rather it involves complex considerations and judgments concerning
differences in financial and operating characteristics and other factors that
could affect the acquisition or public trading values of the companies used in
the foregoing analyses or the company to which they are being compared.
 
  Discounted Cash Flow Analyses
 
   
     Equitable's DCF analyses were based on RenalWest management's financial
forecast and a conservative cash forecast prepared in conjunction with RCG
management for each of the five years ended December 31, from 1996 to 2001. The
forecasted RenalWest revenue growth rates approximate RenalWest's recent
historical growth rates. Equitable derived the unlevered "free cash flow" that
RenalWest was expected to generate in each year from 1996 through 2001.
Equitable discounted these cash flows to present values, applying discount rates
ranging from 10.0% to 14.0%. Equitable arrived at this range of appropriate
discount rates based on its analysis of RenalWest's weighted average cost of
capital. To approximate the terminal value of RenalWest in 2001, Equitable
applied terminal multiples of 10.0x to 12.0x "free cash flow" in 2001.
    
 
     Based on the foregoing analysis, Equitable derived an overall reference
range of enterprise value for RenalWest, ranging from approximately $66.3
million to approximately $85.6 million. Equitable then deducted outstanding
indebtedness from the enterprise value in order to arrive at a range of equity
value for RenalWest of approximately $61.1 million to approximately $80.5
million.
 
  Pro Forma Effect of RCG's Fully Diluted Earnings Per Share
 
     Equitable analyzed the pro forma effect on RCG's earnings per share from
the Merger based on RenalWest management's financial forecast and the
conservative case forecast noted above in Discounted Cash Flow Analyses. This
analysis, using the conservative case forecast, indicated that the Merger would
be accretive for RCG for the years analyzed (1996 and 1997).
 
     In arriving at its opinions, Equitable performed a variety of financial
analyses, including those summarized above. The summary set forth in this
section does not purport to be a complete description of Equitable's analyses.
Equitable believes that its analyses and the summary set forth above must be
considered as a whole and that selecting portions of its analyses, without
considering all analyses, or of the summary above, without considering all
factors and analyses, could create an incomplete view of the processes
underlying Equitable's opinion, so that the ranges of valuation resulting from
any particular analysis described above should not be taken to be Equitable's
view of the actual value of RenalWest. Equitable's analyses depend on numerous
assumptions with respect to industry performance, general business, economic,
market
 
                                       17
<PAGE>   21
 
and financial conditions and other matters, many of which are beyond the control
of RenalWest and RCG. Equitable's analyses are not necessarily indicative of
actual values or actual future results that might be achieved and are not and do
not purport to be appraisals or otherwise reflective of prices at which
companies may actually be sold.
 
     Pursuant to an engagement letter with RCG, Equitable will receive a fee of
$125,000 for its opinion. RCG will also reimburse Equitable for its
out-of-pocket expenses, including reasonable fees and disbursements of counsel.
RCG has also agreed to indemnify Equitable and its affiliates, their respective
directors, officers, partners, agents and employees and each person, if any,
controlling Equitable or any of its affiliates against certain liabilities,
including certain liabilities under the federal securities laws, relating to or
arising out of its engagement.
 
     Equitable is an internationally recognized investment banking firm and
regularly engages in the valuation of businesses and their securities in
connection with mergers and acquisitions and for other purposes. The RCG Board
selected Equitable to act as its financial advisor on the basis of Equitable's
reputation and Equitable's prior work with RCG. In the past, Equitable has
provided investment banking services for RCG for which Equitable received
customary compensation. Equitable holds 30,763 shares of RCG Common Stock and
securities exercisable or convertible into 66,667 shares of RCG Common Stock.
Equitable actively trades the equity securities of RCG for its own account and
for the accounts of its customers and, accordingly, may at any time hold a long
or short position in such securities.
 
FRACTIONAL SHARES
 
     No certificates representing fractional shares of RCG Common Stock will be
issued as a result of the Merger. Any fractional share interest to which a
Member stockholder would otherwise be entitled to receive shall be rounded up to
the nearest whole share if such fraction is .5 or greater and shall be rounded
down to the nearest whole share if such fraction is less than .5.
 
EFFECTIVE TIME OF THE MERGER
 
     If the Merger Agreement is approved by the requisite vote of RCG's
stockholders, and all other required consents and approvals are received, and if
the other conditions to the Merger are satisfied or waived (as permitted), the
Merger shall be consummated and effected on the date and at the time properly
executed Articles of Merger become effective with the Secretary of State of the
State of Arizona (the "Effective Time"). See "The Merger -- Conditions to
Consummation."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following is a summary of certain anticipated federal income tax
consequences of the acquisition of all of the issued and outstanding common
stock of the Members. This summary is based on the Internal Revenue Code of
1986, as amended (the "Code"), regulations and rulings as now in effect or
proposed thereunder, current administrative rulings and practice, and judicial
precedent, all of which are subject to change. Any such change, which may or may
not be retroactive, could alter the tax consequences discussed herein.
 
     It is anticipated that the Merger will constitute a "reorganization" for
federal income tax purposes under Section 368(a) of the Code, with the following
federal income tax consequences:
 
          1. No gain or loss will be recognized by RCG as a result of the
     Merger.
 
          2. The aggregate adjusted tax basis of the shares of RCG Common Stock
     received by the Owners in the Merger will be the same, in each instance, as
     the tax basis of the Member Common Stock surrendered in exchange therefor.
 
          3. No gain or loss will be recognized by the Owners as a result of the
     Merger.

RCG stockholders.
 
AMENDMENTS; TERMINATION
 
     The Merger Agreement may be amended by the action of the parties to it, by
action taken by their respective boards of directors, at any time before or
after approval by the stockholders of RCG and the Members. However, after
stockholder approval, the Merger Agreement may not be amended to materially and
adversely affect the rights of the stockholders, without the further approval of
the stockholders. Any amendment to the Merger Agreement must be in writing and
signed by the party against whom or which enforcement of such amendment is
sought.
 
     The Merger Agreement may be terminated (i) by mutual written consent of RCG
and the RenalWest Parties, (ii) by either RCG or the RenalWest Parties if their
conditions to the Merger have not been satisfied on or before October 31, 1996
(provided the satisfaction of such condition has not been frustrated or made
impossible by the terminating party), and (iii) by RCG or RenalWest if the
Merger has not occurred by November 30, 1996. If the Merger Agreement is

the confidentiality obligations of such parties or arising from any breach of
the representations, warranties, covenants or agreements in the Merger
Agreement.

RIGHT OF FIRST REFUSAL
 
     Pursuant to the Merger Agreement, the Owners have granted RCG a right of
first refusal for a period of three years from the Effective Time, with respect
to any contract or other arrangement with a third party for the sale or
management of such Owner's medical practice on the same terms and conditions as
proposed by such third party, provided that such right of first refusal does not
apply to any transaction by which such Owner's medical practice would join the
multispecialty physician group from which such Owner's practice has received
substantially all of its patient referrals.
 
ACQUISITION PROPOSALS
 
     Until termination of the Merger Agreement pursuant to the terms thereof,
the RenalWest Parties and the Owners have agreed not to (i) solicit any offers

participate in any discussions regarding the sale of any equity securities or a
merger, sale of assets or similar transaction involving any of the RenalWest
Parties or (iii) approve or undertake any such transaction.
 
CONFIDENTIALITY, NONCOMPETITION AND NONSOLICITATION
 
     Subject to the condition described below, the Owners have agreed for a
period of ten (10) years following the Effective Time, not in any manner to
directly or indirectly compete with the business of the RenalWest Parties or to
acquire, establish or own an interest in, or to render managerial, marketing or
other business advice to, any entity that competes with the RenalWest Parties,
in either case within a seventy-five (75) mile radius of the current locations
of the RenalWest Parties (the "Territory"). Such Owners have also agreed for a
period of ten (10) years following the Effective Time, (i) not to divulge or

physician stockholders owning at least sixty percent (60%) of the RCG Common
Stock issued to its physician stockholders in connection with the acquisition by
RCG of their dialysis centers (the "Required Physicians"), revisions where

the period of coverage of their Restrictive Covenants to ten (10) years from
their original starting date. In the event the Required Physicians do not agree
to become subject to such ten (10) year period prior to or at the closing of the
Merger, then the Owners shall be subject to the Restrictive Covenants for five
(5) years.
 
MANAGEMENT AND OPERATIONS AFTER THE MERGER
 
     The Members will be the surviving corporations of the Merger and as a
result RenalWest will become a wholly owned second-tier subsidiary of RCG.
RenalWest and the Members will continue to be governed by the laws of the State
of Arizona. The executive officers and directors of the Merger Corps immediately
prior to the Effective Time will become the executive officers and directors of
the Members.
 
     The Merger Agreement provides that the main office of RenalWest in Mesa,
Arizona will serve as the executive headquarters of RCG's southwest region,
which will include the existing operations of the RenalWest Parties in Arizona
plus all centers newly developed or acquired in the states of Arizona, New
Mexico, Colorado, Utah, Nevada and California (the "Southwest Region"), and that
John Greksa, the current Chief Executive Officer of RenalWest, will serve as the
Chief Operating Officer of the Southwest Region while he is employed by RCG. The
foregoing covenant shall expire upon the later to occur of the fifth
 
                                       20
<PAGE>   24
 
anniversary of the closing date or the date on which Sam A. Brooks, Jr. ceases
to serve as the Chief Executive Officer of RCG. See "-- Interests of Certain
Persons in the Merger."
 
     The Merger Agreement provides that RenalWest and each affiliated physician
practice that has a physician member or employee involved with the use,
operation of or referral of patients to RenalWest's dialysis facilities (the
"Practices"), shall enter into Medical Director Agreements at Closing under
which the Practices shall provide medical director services to RenalWest for the
dialysis facilities operated by RenalWest. Such Medical Director Agreements
shall have an initial term of seven (7) years with renewal terms for additional
three year periods and shall provide for (i) an aggregate annual fee to be paid
by RCG to the Practices of $840,000 (subject to agreed upon modifications) to be
divided among the Practices at their discretion, (ii) certain restrictive
covenants, including but not limited to a covenant not to compete with a
duration of the term of the Medical Director Agreement and three (3) years after
termination of the Medical Director Agreement, and (iii) other customary terms
and conditions.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Pursuant to the Merger Agreement, RCG shall at the closing of the Merger
increase the number of members of its Board of Directors by one and add an
individual specified by the RenalWest Parties as a director, the identity of
whom is subject to the reasonable approval of RCG, to serve an initial term
ending on the date of RCG's 1999 Annual Meeting of its stockholders. Further,
RCG's management shall recommend to its stockholders at such 1999 Annual Meeting
that such designee, or such other designee reasonably approved by RCG, serve for
an additional three (3) year term as a member of the Board of Directors of RCG.
Furthermore, RCG agrees to name a physician specified by the RenalWest Parties
to RCG's Medical Advisory Board, the identity of whom is subject to the
reasonable approval of RCG.
 
     Other than as described herein, no director or executive officer of RCG or
RenalWest, and no associate of any such person, has any substantial interest,
direct or indirect, in the Merger, other than an employment interest or an
interest arising from the ownership of RCG Common Stock or Member Common Stock,
in which case the director or officer receives no extra or special benefit not
shared on a pro rata basis by all other holders of RCG Common Stock or Member
Common Stock. For information as to the ownership of RCG Common Stock, see
"Ownership of RCG Equity Securities."
 
INDEMNIFICATION
 
     The Owners have agreed, jointly and severally to indemnify and hold
harmless RCG, the Members and their respective officers, directors, agents or
affiliates, against any losses and expenses, including reasonable attorney's
fees, arising out of (i) the breach of any representation or warranty of the
RenalWest Parties, and (ii) the nonfulfillment of any covenant or agreement of
the RenalWest Parties. In addition, the Owners have agreed, severally and not
jointly, to indemnify and hold harmless RCG, the Members and their respective
officers, directors, agents or affiliates, against any losses and expenses,
including reasonable attorney's fees, arising out of (i) the breach of any
representation or warranty of such Owner, and (ii) the non-fulfillment of any
covenant or agreement of such Owner. RCG has agreed to indemnify and hold
harmless the Owners, and any of their officers, directors, agents or affiliates,
against any losses and expenses, including reasonable attorney's fees, arising
out of (i) the breach of any representation or warranty of RCG, and (ii) the
non-fulfillment of any covenant or agreement of RCG. No initial claim for
indemnification with respect to any alleged misrepresentation or breach of
warranty may be made by any party after (i) thirty days after first publication
by RCG of audited consolidated financial statements covering an accounting
period after the Closing Date for those items that would be expected to be
encountered in the audit process or (ii) one (1) year after the Closing Date for
all other items. In addition, no claim for indemnification with respect to any
alleged misrepresentation or breach of warranty may be brought by any party
until the aggregate amount of any loss or claim for which indemnification is
sought exceeds $200,000, and then indemnification may only be asserted for
amounts in excess of $200,000. No Owner shall be required to satisfy an
indemnification obligation in excess of one hundred percent (100%) of the
aggregate value of the shares of RCG Common Stock (valued at the Average Trading
Price) to be received by such Owner and RCG shall not be required to satisfy an
indemnification obligation in excess of one hundred percent (100%) of the
aggregate value of all of
 
                                       21
<PAGE>   25
 
the shares of RCG Common Stock (valued at the Average Trading Price) issued as
consideration in the Merger. The indemnification obligations under the Merger
Agreement are to be satisfied solely and exclusively by means of delivery of
shares of RCG Common Stock which, when multiplied by the Average Trading Price,
equals the amount of the indemnification obligation to be satisfied. Except in
cases of fraud or intentional misrepresentation, the indemnification obligations
constitute the exclusive remedy for any inaccuracy or breach of a representation
or warranty. The Average Trading Price is $30.00.
 
EXPENSES AND FEES
 
     The Merger Agreement provides that each of the parties to the Merger
Agreement shall bear and pay all costs and expenses incurred by it or on its
behalf in connection with the Merger, provided, however, all legal, accounting
and other fees and expenses incurred by the RenalWest Parties and the Owners
concerning the Merger in excess of $150,000 shall be paid by the Owners at the
closing of the Merger or thereafter when due. See "The Merger -- Amendment;
Termination."
 
ACCOUNTING TREATMENT
 
     Consummation of the Merger is conditioned on the Merger being accounted for
on a pooling-of-interests accounting basis and the receipt by RCG of a letter
from Ernst & Young LLP with respect thereto. See "Conditions to Consummation."
Under this method of accounting, as of the Effective Time, the assets and
liabilities of RenalWest would be added to those of RCG at their recorded book
values and the stockholders' equity accounts of RCG and RenalWest would be
combined on RCG's consolidated balance sheet. Under the pooling-of-interests
accounting method, income and other financial statements of RCG issued after
consummation of the Merger will be restated retroactively to reflect the
combined consolidated financial position and results of operations of RCG and
RenalWest as if the Merger had taken place prior to the periods covered by such
consolidated financial statements and to reflect the accounting policies of RCG.
 
     The unaudited pro forma condensed combined financial statements contained
in this Proxy Statement have been prepared using the pooling-of-interests
accounting basis to account for the Merger. See "Unaudited Pro Forma Condensed
Combined Financial Statements."
 
RESALES OF THE RCG COMMON STOCK ISSUED IN THE MERGER; REGISTRATION RIGHTS
 
     The RCG Common Stock to be issued to the Owners in connection with the
Merger will be "restricted stock" under the Securities Act. Owners may not sell
their shares of RCG Common Stock acquired in connection with the Merger except
pursuant to an effective registration statement under the Securities Act
covering such shares, or in compliance with Rule 144 promulgated under the
Securities Act or another applicable exemption from the registration
requirements of the Securities Act.
 
     As a condition precedent to the obligations of the RenalWest Parties to
consummate the Merger, RCG shall have obtained the requisite approval of its
stockholders currently holding registration rights for the grant of the
registration rights described below to the Owners. Under the Merger Agreement,
RCG is obligated to undertake reasonable commercial efforts to file by November
30, 1996 a registration statement under the Securities Act ("Secondary
Offering"), pursuant to which the Owners may sell, to the extent permissible
under the "pooling of interests" rules, up to forty percent (40%) of their
shares of RCG Common Stock. If RCG has not caused the Secondary Offering to
become effective prior to February 7, 1997, then Owners holding twenty percent
(20%) of the shares of RCG Common Stock issued in the Merger have the right to
require RCG to file a registration statement under the Securities Act for an
offering of not less than an aggregate of ten percent (10%) of the RCG Common
Stock originally held by all Owners and not more than an aggregate of twenty
percent (20%) of the RCG Common Stock originally held by each such Owners making
such request. RCG is obligated to effect only one such registration pursuant to
such a request, subject to certain exceptions. In addition, in the event RCG
proposes to register under the Securities Act any RCG Common Stock for its own
account or for the account of others at any time prior to the second anniversary
of the date the shares of RCG Common Stock are issued to the Owners in the
Merger, subject to certain exceptions, the Owners have the right to require RCG
to include up to forty percent (40%) of their shares of
 
                                       22
<PAGE>   26
 
RCG Common Stock in such registration, subject to the right of any managing
underwriter of the offering to exclude some or all of the shares for marketing
reasons. In general, all fees, costs and expenses of such registrations (other
than underwriting commissions, dealer's fees, brokers' fees and concessions
applicable to shares of RCG Common Stock registered and any counsel for the
selling stockholders) will be borne by RCG. The registration rights granted to
the Owners may be assigned to a permitted transferee or assignee of the RCG
Common Stock from the Owner provided that certain conditions are met.
 
     RCG agrees to undertake reasonable commercial efforts to satisfy its
reporting requirements under the Exchange Act and to take other reasonable and
appropriate actions to enable the Owners to participate in such Secondary
Offering. In the event the Secondary Offering occurs and the Owners are not able
to participate through no fault of them or the RenalWest Parties, RCG has agreed
to provide reasonable assistance to the Owners to aid them in obtaining a loan
or loans from a third party until June 30, 1997 (the "Maturity Date"),
including, if necessary, a guaranty by RCG to such third party lender of up to
an aggregate of $1,500,000 of such loan or loans. Such loans and any guaranty by
RCG are to be secured by an adequate number of the Owners' shares of RCG Common
Stock. If such loan or loans are not available on terms and conditions otherwise
reasonably acceptable to the Owners, RCG has agreed to provide a loan or loans
directly to the Owners of up to an aggregate amount of $1,500,000 (to be
allocated among the Owners at their discretion) which will (i) mature on the
Maturity Date, (ii) contain terms and conditions to the Owners no less favorable
than are available to RCG from its third party lenders, and (iii) be secured by
an adequate number of shares of RCG Common Stock. Any of the foregoing loans
shall be paid prior to the Maturity Date to the extent of first available
proceeds from any resale of the Owner's shares of RCG Common Stock under the
registration rights granted to the Owners.
 
EFFECT OF THE MERGER ON RIGHTS OF RCG STOCKHOLDERS
 
     Consummation of the Merger and issuance of shares of RCG Common Stock in
connection therewith will not result in any change in the rights of RCG
stockholders under the provisions of the General Corporation law of Delaware or
RCG's Certificate of Incorporation or Bylaws. In connection with the Merger, RCG
will issue an aggregate of 2,400,000 shares of RCG Common Stock to the Owners,
which amount will represent approximately 19% of the outstanding shares of RCG
Common Stock after consummation of the Merger.
 
CONDUCT OF BUSINESS OF THE RENALWEST PARTIES PENDING THE MERGER
 
     Pursuant to the Merger Agreement, the RenalWest Parties and RCG have agreed
prior to the Effective Time that the RenalWest Parties shall restrict certain of
their activities, except with the prior written consent of RCG and except as
necessary to effect the transactions contemplated in the Merger Agreement. To
this end, the RenalWest Parties shall: (i) operate their businesses in the
usual, regular and ordinary course of business, consistent with past practices;
(ii) use reasonable commercial efforts to preserve intact their business
organization, licenses, permits, government programs, private programs and
customers; (iii) use reasonable commercial efforts to retain the services of its
employees, agents and consultants on terms and conditions not less favorable
than those existing prior to the date of the Merger Agreement and to ensure that
there are no material or adverse changes to employee relations; (iv) keep and
maintain its assets in their present condition, repair and working order, except
for normal depreciation and wear and tear, and maintain its insurance, rights
and licenses; (v) pay all accounts payable of the RenalWest Parties in
accordance with past practice and collect all accounts receivable in accordance
with past practice, but not less than in accordance with prudent business
practices; (vi) consult with RCG prior to undertaking any new business

the date of the Merger Agreement or which become due prior to the Effective Time

the filing deadlines granted); provided, however, that any such tax return shall
not be filed without a reasonable opportunity for prior review and comment by
RCG; (x) as soon as reasonably practicable after they become available, but in
no event more than thirty (30) days following the end of each calendar month,
deliver to RCG true and complete copies of its monthly financial statements for
each calendar month ending subsequent to the date hereof on the format
historically utilized by the RenalWest Parties; (xi) perform in all material
respects all obligations under agreements relating to or affecting its assets,
properties or rights, except for the failure of which performance would not have
a material adverse effect on the business of the RenalWest Parties taken as a
whole, financial or otherwise; (xii) keep in full force and effect present
insurance policies or other comparable insurance coverage; and (xiii) notify RCG
of (i) any event or circumstance which is reasonably likely to have a material
adverse effect on the RenalWest Parties or would cause or constitute a breach of
any of the RenalWest Parties' representations, warranties or covenants contained
in the Merger Agreement; or (ii) any unexpected change in the normal course of
business or in the operation of the assets of the RenalWest Parties' assets, and
of any governmental complaints, investigations or hearings (or communications
indicating that the same may be contemplated), adjudicatory proceedings, budget
meetings or submissions involving any material property. The RenalWest Parties
have agreed to keep RCG fully informed of such events and to permit RCG's
representatives prompt access to all materials prepared in connection therewith.
 
     In addition, the RenalWest Parties have covenanted and agreed that they
will not do any of the following without the prior written consent of the RCG:
(i) take any action which would (a) adversely affect the ability of any party to
the Merger Agreement to obtain any consents required for the transactions
contemplated thereby, or (b) adversely affect the ability of any party hereto to
perform its covenants and agreements under the Merger Agreement and related
documents; (ii) amend any of its organizational or governing documents except as
provided in the Merger Agreement or for the purpose of accomplishing the Merger;
(iii) incur any additional debt obligation or other obligation for borrowed
money in excess of an aggregate of $100,000 except in the ordinary course of the

permit any such lien to exist; (iv) repurchase, redeem, or otherwise acquire or
exchange, directly or indirectly, any equity securities of any RenalWest Party,

$50,000 other than in the ordinary course of business for reasonable and
adequate consideration; (viii) purchase any securities or make any material

to any existing employee benefit plans other than any such change that is

(xv) except in the ordinary course of business and, even if in the ordinary

OWNERS' REPRESENTATIVE
 
     Pursuant to the Merger Agreement, each of the Owners has appointed Jeff
Weintraub as his attorney-in-fact and agent in connection with the transactions
and agreements contemplated by the Merger Agreement with respect to matters
subsequent to the Effective Time (the "Owners' Representative"). The Owners'
Representative has the authority to take all actions contemplated by the Merger
Agreement on behalf of the Owners and to execute and deliver all instruments,
certificates and other documents incident to the Merger.
 
     Each Owner will be bound by all agreements and determinations made by and
documents executed and delivered by the Owners' Representative. The Owners will
indemnify the Owners' Representative for any and all liability, loss, cost,
damage or expense (including attorneys' fees) incurred without bad faith on the
part of the Owner's Representative in connection with his or her duties as
Owners' Representative.
 
                                  PROPOSAL II
 
                     APPROVAL OF PROPOSED AMENDMENT TO THE
                             1996 STOCK OPTION PLAN
 
     The Option Plan was adopted by the Board of Directors and approved by the
sole stockholder of RCG effective as of January 15, 1996. The Board of Directors
has adopted, subject to stockholder approval at the Special Meeting, an
amendment to the Option Plan. If approved by the stockholders, the proposed
Amendment will be effective as of the date of the Special Meeting.
 
     The Board of Directors believes that stock ownership is an important
incentive for key employees, consultants and others in a position to influence
the success of RCG. The purpose of the Option Plan is to provide a means by
which selected key employees of, and consultants and advisors to, RCG and its
affiliates may be given an opportunity to purchase RCG Common Stock.
 
     The following is a summary of the Option Plan and the proposed amendments
thereto (i) to increase from 488,448 to 1,000,000 the number of shares of RCG
Common Stock authorized to be issued upon exercise of options granted under the
plan, and (ii) to eliminate certain plan restrictions that are no longer
necessary in light of recent amendments to the rules of the Commission
promulgated under Section 16 of the Exchange Act. A copy of the full text of the
Option Plan, as amended, is attached hereto as Appendix C.
 
GENERAL
 
     Eligible Participants.  Options may be granted under the plan only to
individuals who are officers or other key employees (including employees who
also are directors or officers) of RCG or a subsidiary, or bona fide
consultants, as determined by the Committee (as defined below). Certain
restrictions apply to holders of ten percent or more of the RCG Common Stock.
The number of eligible participants in the plan as of June 30, 1996 was
approximately 175 persons.
 
                                       25
<PAGE>   29
 
     Administration.  The Option Plan is currently is administered by a
committee (the "Committee") appointed by the Board of Directors from time to
time and consisting of at least two members of the Board, each of whom must be a
"disinterested person" as defined in former Rule 16b-3 under the Exchange Act.
No member of the Committee is eligible to participate in the Option Plan while
serving as a member of the Committee. Rule 16b-3 has recently been amended to
delete the requirement that a qualifying plan be administered by "disinterested
persons" and, instead, to introduce the concept of "non-employee directors" who
may approve options that are exempt from the short-swing liability provisions of
Section 16 of the Exchange Act. Consequently, the Amendment would require that
the Committee consist of at least two members of the Board, each of whom is both
(i) a "non-employee director" as such term is defined in new Rule 16b-3, and
(ii) an "outside director" as that term is used in Section 162 of the Code and
the regulations thereunder. Consistent with the recent amendments to Rule 16b-3,
the Amendment would also omit the current prohibition on Committee members being
participants in the Option Plan.
 
     In the absence of an appointment of a Committee, the RCG Board of Directors
shall serve as the Committee. Subject to the terms of the Option Plan, the
Committee has the exclusive power, authority and discretion to designate
participants; determine the type or types of options to be granted to each
participant; determine the number of options to be granted and the number of
shares of RCG Common Stock to which an option will relate; determine the terms
and conditions of any option granted under the Option Plan, including but not
limited to, the exercise price, any restrictions or limitations on the option,
any schedule for lapse of forfeiture restrictions or restrictions on the
exercisability of an option, and accelerations or waivers thereof, based in each
case on such considerations as the Committee in its sole discretion determines;
determine whether, to what extent, and under what circumstances an option may be
settled in, or the exercise price of an option may be paid in, cash, shares of
RCG Common Stock, or other property, or an option may be canceled, forfeited, or
surrendered; prescribe the form of each option agreement, which need not be
identical for each participant; decide all other matters that must be determined
in connection with an option; establish, adopt or revise any rules and
regulations as it may deem necessary or advisable to administer the Option Plan;
and make all other decisions and determinations that may be required under the
Option Plan or as the Committee deems necessary or advisable to administer the
plan.
 
     Number of Shares Available.  The maximum number of shares of RCG Common
Stock for which options may be granted under the Option Plan currently is
488,448 and, if the proposed Amendment is approved by the stockholders at the
Special Meeting, will be increased to 1,000,000. A primary reason additional
shares are needed under the Option Plan is to enable RCG to grant options to key
employees who have been or will be employed by RCG in connection with its
acquisitions. To the extent that an option is canceled, terminates, expires or
lapses for any reason, any shares of stock subject to the option will again be
available for the grant of options under the plan. (In this regard, the
Amendment would omit certain re-use restrictions that are no longer applicable
under the recent amendments to Rule 16b-3 under the Exchange Act.) The maximum
number of shares of stock with respect to one or more options that may be
granted to any one participant in any one taxable year is 100,000, subject to
adjustment as set forth in the plan. The number of shares of RCG Common Stock
available under the Option Plan is subject to adjustment in the event of a stock
split, stock dividend, recapitalization or other similar action. The shares of
RCG Common Stock distributed pursuant to an option may consist, in whole or in
part, of authorized and unissued stock, treasury stock or stock purchased on the
open market.
 
     Amendment and Termination.  As currently written, the Plan requires
stockholder approval for certain specified plan amendments as required by former
Rule 16b-3 under the Exchange Act. Consistent with the greater flexibility
afforded by recent amendments to such Rule 16b-3, the Amendment would permit the
Committee, at any time with the approval of the Board, to terminate, amend or
modify the Option Plan without stockholder approval; provided, however, that the
Committee may condition any amendment on the approval of stockholders if such
approval is necessary or deemed advisable with respect to tax, securities or
other applicable laws, policies or regulations. No termination, amendment, or
modification of the Option Plan shall adversely affect any option previously
granted under the plan, without the written consent of the option holder.

STOCK OPTIONS
 
     Stock Options.  The Committee is authorized to grant options, which may be
incentive stock options or nonqualified stock options, to participants. All
options will be evidenced by a written option agreement between RCG and the
participant, which will include such provisions as may be specified by the
Committee. The terms of any incentive stock option must meet the requirements of
Sections 421, 422 and 424 of the Code.
 
   
     Option Price.  The exercise price of each incentive stock option granted
under the Option Plan will not be less than 100% of the fair market value of RCG
Common Stock on the date the option is granted. The Committee may elect to grant
non-qualified stock options with an exercise price of less than the fair market
value of RCG Common Stock on the date such option is granted. The closing price
for RCG's Common Stock on the Nasdaq National Market was $34.38 per share as of
September 5, 1996.
    
 
     Duration of Options.  The Committee may provide in the option agreement for
the termination of all or any portion of the options under certain
circumstances, including, without limitation, termination of a participant's
employment, provided that the Committee may distinguish among various causes of
termination as the Committee deems appropriate. In addition, the Committee may
provide that if a Participant's employment is terminated: (i) such participant's
option(s) may be exercised for specified periods thereafter but no later than
the expiration date of such option; (ii) to the extent not fully exercisable on
the date of termination of employment, such option may continue to become
exercisable within the term of the option; or (iii) some or all of the options
not fully exercisable on the date of termination of employment may be deemed
fully exercisable.
 
     Exercise.  Each option may be exercised at such time or times as may be
determined by the Board or the Committee. (In this regard, consistent with
recent amendments to Rule 16b-3 under the Exchange Act, the Amendment would omit
the current plan provision that prohibits certain participants from exercising
an option for six months after grant.) The Committee also shall determine the
performance or other conditions, if any, that must be satisfied before all or
part of an option may be exercised.
 
     Payment.  The Committee shall determine the methods by which the exercise
price of an option may be paid, the form of payment, including, without
limitation, cash, shares of RCG Common Stock, or other property (including
"cashless exercise" arrangements), and the methods by which shares of RCG Common
Stock shall be delivered or deemed to be delivered to participants. The
Committee may, in the exercise of its discretion, allow a participant to pay the
exercise price of an option by directing RCG to withhold from the shares of
stock that would otherwise be issued upon exercise of the option that number of
shares of RCG Common Stock having a fair market value on the exercise date equal
to the exercise price, all as determined pursuant to rules and procedures
established by the Committee.
 
     Restrictions on Transfer.  No right or interest of a participant in any
option granted under the Option Plan may be pledged, encumbered, or hypothecated
to or in favor of, or be subjected to any lien, obligation, or liability of such
participant to, any party other than RCG or a subsidiary. No such option is
assignable or transferable by a participant other than by will or the laws of
descent and distribution or, except in the case of an Incentive Stock Option,
pursuant to a qualified domestic relations order. However, a participant may, in
the manner determined by the Committee, designate a beneficiary to exercise the
rights of the participant upon the participant's death. Any Incentive Stock
Option shall be exercisable during the lifetime of the person to whom the option
is granted only by such person.
 
     Adjustments.  If any change is made in the stock subject to the Option Plan
or subject to any option granted thereunder (through recapitalization,
reclassification, stock split, combination of shares, stock dividend, or
transaction having similar effect), the Option Plan and outstanding options will
be appropriately adjusted.
 
     Acceleration Upon Change in Control.  In the event of a Change in Control
(as defined in the Option Plan) followed by a participant's termination of
employment (other than by reason of the participant's death, disability,
resignation without good reason or termination for cause) within twelve months
thereafter, then all of such participant's unexercised options (whether vested
or not vested) shall automatically vest and become unforfeitable and shall be
cashed out at the greater of (i) the highest closing price per share paid for
the purchase of RCG Common Stock in a national securities market during the 90
day period ending on the date
 
                                       27
<PAGE>   31
 
of the Change in Control (the "Change in Control Price") or (ii) the fair market
value of the RCG Common Stock on the date of such termination. Upon a Change in
Control that results directly or indirectly in the RCG Common Stock (or the
stock of any successor received in exchange therefor) ceasing to be publicly
traded in a national securities market, all unexercised options (whether vested
or not vested) shall automatically vest and become unforfeitable and shall be
cashed out at the Change in Control Price. Upon a Change in Control, no action
may be taken that would adversely affect the rights of any participant or the
operation of the plan with respect to any option to which a participant may be
entitled on or prior to the date, or as a result, of the Change in Control.
Under certain conditions, the Board of Directors may determine that events
otherwise constituting a change in Control shall not be so considered.
Consistent with recent amendments to Rule 16b-3 under the Exchange Act, the
Amendment would omit the current plan provision that prohibits certain
participants from receiving consideration for an option that has been
outstanding for less than six months.
 
     Modification and Renewal.  The Committee may modify, renew or accept the
surrender of outstanding options issued under the Option Plan (or the surrender
of similar grants issued under any other plan of RCG or a subsidiary), including
the acceleration or waiver of any vesting or other restrictions or limitations,
or the conversion of such options (with appropriate adjustments) to be
applicable to the securities of any successor corporation to RCG, and the
Committee may authorize new options pursuant to the Option Plan in substitution
for any outstanding options. Any substituted, modified or converted options may
bear such different or additional terms and conditions as the Committee shall
deem appropriate within the limitations of the Option Plan. The determination of
the Committee as to the terms of any of the foregoing may be made without regard
to whether a Change in Control has or has not occurred (or whether the Board of
Directors has determined that any event shall not be considered to be a Change
in Control) and shall be conclusive and binding notwithstanding the provisions
of the respective option agreements regarding exercisability. No modification of
an option shall, without the consent of the participant, adversely affect the
rights or obligations of such participant with respect to such option.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     Non-qualified Stock Options.  Under present federal income tax regulations,
there will be no federal income tax consequences to either RCG or the
participant upon the grant of a non-discounted non-qualified option. However,
the participant will realize ordinary income on the exercise of a non-qualified
option in an amount equal to the excess of the fair market value of the RCG
Common Stock acquired upon the exercise of such option over the exercise price,
and RCG will receive a corresponding deduction. The gain, if any, realized upon
the subsequent disposition by the participant of the RCG Common Stock will
constitute short- or long-term capital gain, depending on the participant's
holding period. If a non-qualified option is granted with an exercise price
substantially less than the fair market value of the RCG Common Stock on the
date of grant, it is possible that the Internal Revenue Service could take the
position that the participant will realize ordinary income on the date of grant
in an amount equal to the excess of the fair market value of the stock on the
date of grant over the exercise price. If so, RCG should receive a corresponding
deduction.
 
     Incentive Stock Options.  Under present federal income tax regulations,
there will be no federal income tax consequences to either RCG or the
participant upon the grant of an incentive stock option or the exercise thereof
by the participant. If the participant holds the shares for the greater of two
years after the date the option was granted or one year after the acquisition of
such shares (the "required holding period"), the difference between the
aggregate option price and the amount realized upon disposition of the shares
will constitute a long-term capital gain or loss, and RCG will not be entitled
to a federal income tax deduction. If the shares are disposed of in a sale,
exchange or other "disqualifying disposition" during the required holding
period, the grantee will realize taxable ordinary income in an amount equal to
the excess of the fair market value of the shares purchased at the time of
exercise over the aggregate option price and RCG will be entitled to a federal
income tax deduction equal to such amount.

BENEFITS TO NAMED EXECUTIVE OFFICERS AND OTHERS
 
     As of June 30, 1996, stock options had been granted under the Option Plan
to the persons and groups shown in the table below. The Committee has not yet
made any determination as to which eligible participants will be awarded options
under the Option Plan in the future. Consequently, it is not presently possible
to determine, with respect to the persons and groups shown in the table below,
the benefits or amounts that will be received in the future by such persons or
groups pursuant to the Option Plan.

                RCG SELECTED HISTORICAL COMBINED FINANCIAL DATA
 
   
     The Selected Combined Financial Data -- Renal Care Group, Inc. represents
the historical results of operations of the registrant, including the results of
operations of Main Line Suburban Dialysis Centers, Inc. ("Main Line") which was
acquired in April 1996 in a pooling of interests transaction. The registrant in
February 1996 acquired the Founding Companies (Kidney Care, Kansas, DMN, Tyler
and Tennessee) (the "Combination"), when it also completed an initial public
offering of 4,485,000 shares of RCG Common Stock (the "Offering"). Although the
Combination was not a pooling-of-interests transaction, it was accounted for
using historical cost, in accordance with Securities and Exchange Commission
Staff Accounting Bulletin No. 48, as then in effect, because no single owner
group from any of the Founding Companies held more than a 50% equity interest in
RCG as of the closing of the Offering. Accordingly, RCG beginning February 1996
recorded the net assets acquired at the Founding Companies' historical cost
basis, as determined by generally accepted accounting principles.
    
 
   
     The Selected Combined Financial Data -- Founding Companies represents the
combined historical operations of Kidney Care, Kansas, DMN, Tyler and Tennessee
as if they had been combined for periods prior to their acquisition by RCG. Most
of the Founding Companies were either subchapter S corporations or not-
for-profit and thus paid no federal or state income taxes.
    
 
     The Selected Combined Financial Data -- Renal Care Group, Inc. and Founding
Companies Combined represent the results of operations had the Founding
Companies and RCG been combined on January 1, 1991, without giving effect to the
Offering, for periods prior to February 1, 1996.
 
     The selected combined financial data for RCG for the calendar years ended
December 31, 1994 and 1995 and the Founding Companies for the calendar years
ended December 31, 1992, 1993 and 1994 are derived from audited data included
elsewhere in this Proxy Statement. The unaudited combined financial statements

(1) The financial information for each of the years ended December 31, and for
     the six months ended June 30, 1995, include the results of operations of
     Renal Care Group, Inc. and the historical operations of Main Line Suburban
     Dialysis Centers, Inc. ("Main Line"). Main Line was merged into Renal Care
     Group effective April 26, 1996 and was accounted for as a pooling of
     interests.
   
(2) The financial information for the six months ended June 30, 1996, include
     the results of operations for Renal Care Group (of Delaware) since the date
     it began business on February 1, 1996. The information includes the results
     of Main Line and all Founding Companies for the period from February 1,
     1996 to June 30, 1996. All periods prior to January 1, 1996 represent the
     operations of Main Line which was a pooling-of-interests transaction. Main
     Line was a Subchapter S Corporation for income tax purposes and thus there
     is no income tax provision for periods prior to January 1, 1996.

(1) The financial information for each of the years ended December 31 includes
     the results of operations of Kidney Care for the fiscal year ended on
     January 31 following the year indicated.
    
(2) The Combination was accounted for using historical cost, in accordance with
     Securities and Exchange Commission Staff Accounting Bulletin No. 48,
     because no single owner group from any of the Founding Companies will hold
     more than a 50% equity interest in RCG as of the closing of the Offering.
     Accordingly, RCG beginning February, 1996 recorded the net assets acquired
     at the Founding Companies' historical cost basis, as determined by
     generally accepted accounting principles.
(3) The financial information for the six months ended June 30, 1996 represent
     only the historical results of operations of all the Founding Companies for
     the month of January as a result of the Founding Companies being acquired
     by RCG effective February 1, 1996.

(1) The financial information for each of the years ended December 31, includes
    the results of operations of Kidney Care for the fiscal years ended January
    31, following the year indicated.
(2) The Combination is accounted for using historical cost, in accordance with
    Securities and Exchange Commission Staff Accounting Bulletin No. 48, because
    no single owner group from any of the Founding Companies held more than 50%
    equity interest in RCG as of the closing of the Offering. Accordingly, RCG
    has recorded the net assets acquired at the Founding Companies' historical
    cost basis, as determined by generally accepted accounting principles.
(3) For all periods presented, the selective combined financial statements are
    representative of the financial position and results of operations of the
    Founding Companies and RCG and Main Line. Main Line merged with RCG April
    26, 1996 and operates five dialysis centers serving approximately 350
    patients. The transaction is accounted for as a pooling of interests.
   
(4) Pro forma information gives effect to (i) the Combination, (ii) the sale of
    shares of RCG Common Stock in the offering and the application of the net
    proceeds. The pro forma adjustments included in the income statement data
    are as follows:
    
   
    (a) Patient care costs have been decreased due to purchase of facilities
       from the owners of Kansas and Kidney Care.
    
    (b) General and administrative expenses have been increased due to
       additional corporate shared service costs.
   
    (c) Depreciation and amortization has been increased due to additional
       depreciation on facilities purchased from the owners of Kansas and Kidney
       Care and increased amortization as a result of DMN's buyout of a 50%
       interest in a joint venture.
    
    (d) Interest expense has been reduced to reflect the repayment of both
       existing and assumed debt from the net proceeds of the Offering.
(5) Pro forma adjustments are not considered necessary due to the Combination
    being effected on February 1, 1996. Adjustments to the January operating
    results have been determined to be immaterial.

                    RCG MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion should be read in conjunction with the information
contained in the Financial Information referenced in the Index to Financial
Statements, including the Notes thereto, and the other financial information
appearing elsewhere in this Proxy Statement.
 
OVERVIEW
 
     Renal Care Group is a specialized provider of nephrology services that was
founded in June 1995 to focus on the provision of care to patients with kidney
disease, including patients suffering from chronic kidney failure, and to
provide clinical and practice management services to nephrologists. Simultaneous
with the closing of the Offering, RCG acquired the Founding Companies, which
have been operating outpatient dialysis businesses as separate, independent
entities for an average of approximately 14 years. Because the Founding
Companies are independent entities that have not been operated by RCG's
management prior to the Combination, the historical combined results do not
reflect RCG's actual operations on a consolidated basis and therefore may not be
indicative of future performance. For all periods presented, the Combined
Financial Statements include the information of the Founding Companies and Main
Line Suburban Dialysis Centers, Inc. ("Main Line"), a merger completed in April
1996. Main Line, of Wynnewood, Pennsylvania, operates five dialysis centers
serving approximately 350 patients in the suburban Philadelphia area. The
transaction is accounted for as a pooling of interests. The Combined Financial
Statements include the financial information on a historical basis, as if these
groups had always been members of the same operating entity without giving
effect to the Combination, the Offering, or the realization of any operating
efficiencies that RCG believes typically would be attainable in an integrated
organization.
 
     RCG believes that the Founding Companies and Main Line, on an individual
basis, generally have not had the management, capital and other resources
required to generate sustainable internal growth in the increasingly competitive
dialysis industry. As part of its strategy, RCG assembled an experienced
management team that has become the executive management of RCG and which RCG
believes will enable it to pursue a more progressive growth strategy.
Significant factors that influence internal growth in the dialysis industry
include the number of nephrologists associated with a company's dialysis centers
and the availability of capital to fund the development of new centers. A key
component of RCG's strategy is to increase internal growth by providing
management, capital and other resources required to develop new centers and to
recruit additional nephrologists to increase utilization of RCG's existing
network of dialysis centers. In the opinion of management, the information
contained herein related to June 30, 1996 interim financial statements reflects
all adjustments necessary to make the results of operations for the interim
periods a fair statement of such operations. All such adjustments are of a
normal recurring nature. Operating results for the interim period are not
necessarily indicative of results which may be expected for the year as a whole.
 
     Since the Combination, RCG has implemented company-wide supply agreements,
insurance contracts and other such arrangements. Other operating efficiencies
that RCG has initiated include consolidation of employee benefits, insurance,
cash management and other functions. Furthermore, RCG intends to focus on
improving operating performance by implementing previously adopted standard
clinical protocols and operating procedures. RCG cannot presently predict the
future effect, if any, on its financial performance from any of these or other
similar opportunities to improve the operations of the group. RCG believes that
it will be able to realize economies of scale in acquired and managed operations
by consolidating corporate and regional management expenses. However, a portion
of the operating efficiencies that may be achieved in these organizations will
be offset by the need for increased general and administrative expenses at RCG's
corporate headquarters.
 
     Subsequent to the Combination, RCG has focused on expansion of its business
through the acquisition, development and management of dialysis centers in
nephrology practices. In April 1996, RCG announced an agreement to operate and
manage the outpatient dialysis activities of The Cleveland Clinic Foundation
located in Cleveland, Ohio. The Cleveland Clinic Foundation operates two
dialysis facilities staffed by eleven nephrologists serving approximately 370
patients. In April 1996, RCG completed the merger with Main Line.
 
                                       34
<PAGE>   38
 
On July 1, 1996, RCG announced that it had completed a merger with Nephrology
Center, Inc., which currently services approximately 250 patients at locations
in Pensacola and Crestview, Florida.
 
SOURCES OF NET REVENUE
 
     Net revenue of the Founding Companies and Main Line has been derived
primarily from the following sources: (i) outpatient hemodialysis services; (ii)
ancillary services associated with dialysis, primarily the administration of
EPO; (iii) home dialysis services; (iv) inpatient hemodialysis services provided
pursuant to contracts with acute care hospitals; (v) management contracts with
medical university dialysis programs; and (vi) laboratory services. ESRD
patients typically receive 156 dialysis treatments per year, with reimbursement
for these services provided primarily by the Medicare ESRD program based on
rates that are established by HCFA. For the six months ended June 30, 1996,
approximately 78% of RCG's net revenue was derived from reimbursement under the
Medicare and Medicaid programs. Medicare reimbursement is subject to rate and
other legislative changes by Congress and periodic changes in regulations,
including changes that may reduce payments under the ESRD program. For patients
with health insurance, dialysis generally is reimbursed at rates higher than
Medicare during the first 18 months of treatment, after which time Medicare
becomes the primary payor. Reimbursement for dialysis services provided pursuant
to a hospital contract is negotiated with the individual hospital and generally
is higher on a per treatment equivalent basis than the Medicare rate. Because
dialysis is a life-sustaining therapy used to treat a chronic disease,
utilization is predictable and is not subject to seasonal fluctuations.
 
RESULTS OF OPERATIONS
 
     The following table sets forth certain income statement items of the
Founding Companies and Main Line, on a combined basis, expressed as a percentage
of net revenue for the years ended December 31, 1993, 1994 and 1995 and for the
six months ended June 30, 1995 and 1996.

SIX MONTHS ENDED JUNE 30, 1996 COMPARED TO SIX MONTHS ENDED JUNE 30, 1995
 
     Net Revenue.  Net revenue increased from $40.2 million for the six months
ended June 30, 1995 to $45.4 million for the six months ended June 30, 1996, an
increase of $5.2 million or 12.9%. This increase resulted primarily from a 7.7%
increase in the number of treatments from 227,948 in the 1995 period to 245,446
in the 1996 period and a 2.8% increase in the average revenue per treatment from
$176 in 1995 to $181 in 1996. The remaining revenue increase is a result of
management fee income and higher than expected earnings of certain partnerships
in which RCG has a 50% interest. The revenue per treatment increase is due to an
increase in higher revenue generating acute treatments and greater than expected
Erythropoietin ("EPO") utilization.
 
                                       35
<PAGE>   39
 
     Patient Care Costs.  Patient care costs consist of costs directly related
to the care of patients, including direct labor, drugs, and other medical
supplies, and operational costs of facilities. Patient care costs increased from
$29.6 million for the six months ended June 30, 1995 to $33.1 million for the
six months ended June 30, 1996, an increase of $3.5 million or 11.8%. This
increase was due to the increase in the number of associated treatments, which
caused a corresponding increase in the use of drugs and supplies. Patient care
costs as a percent of net revenue decreased from 73.5% in the 1995 period to
73.0% in the 1996 period. Average patient care cost per treatment increased from
$130 in 1995 to $135 in 1996 or 3.8%. This increase is due to normal healthcare
inflation, higher than expected EPO cost, and other non-chargeable drug
utilization costs, and the increase in higher cost acute treatments.
 
     General and Administrative Expenses.  General and administrative expenses
include corporate office costs and clinic costs not directly related to the care
of patients, including clinic administration, accounting, billing and
information systems. General and administrative expenses increased from $3.5
million for the six months ended June 30, 1995 to $3.6 million for the six
months ended June 30, 1996, an increase of $100,000 or 2.9%. General and
administrative expenses decreased as a percent of revenue in the 1996 period by
0.7% primarily due to the higher revenues for the six month period. The increase
is a result of increased corporate overhead expenses partially offset by reduced
management fees paid by Main Line to its owners.
 
     Provision for Doubtful Accounts.  The provision for doubtful accounts
increased from $819,000 for the six months ended June 30, 1995 to $883,000 for
the six months ended June 30, 1996. The provision for doubtful accounts as a
percent of net revenue decreased from 2.1% in the 1995 period to 1.9% in the
1996 period. Provision for doubtful accounts is a function of patient mix,
billing practices and other factors. It is RCG's practice to reserve for
doubtful accounts in the period in which the revenue is recognized based on
management's estimate of the net collectibility of the accounts receivable.
 
     Depreciation and Amortization.  Depreciation and amortization remained
unchanged at $1.2 million for the six months ended June 30, 1995 and for the six
months ended June 30, 1996.
 
     Income from Operations.  Income from operations increased from $5.2 million
for the six months ended June 30, 1995 to $5.8 million for the six months ended
June 30, 1996, an increase of $600,000, or 11.5%. Income from operations as a
percent of net revenue increased from 12.8% in the 1995 period to 12.9% in the
1996 period. Income from operations increased due to the increase in net revenue
in excess of patient care costs, which was primarily due to an increase in the
growth rate of the number and types of treatments.
 
     Interest Income/Expense.  Interest expense decreased from $120,000 for the
six months ended June 30, 1995 to a net interest income of $408,000 for the six
months ended June 30, 1996, a net increase of $528,000. The increase is
primarily due to the investment of the Offering proceeds and the payoff of
substantially all borrowings of the Founding Companies.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
     Net Revenue.  Net revenue increased from $80.0 million for the year ended
December 31, 1994 to $82.6 million for the year ended December 31, 1995, an
increase of $2.6 million, or 3.3%. This increase resulted primarily from a 2.8%
increase in the number of treatments from 454,187 in the 1994 period to 466,994
in the 1995 period and a 0.5% increase in the average revenue per treatment from
$176 in 1994 to $177 in 1995. The revenue per treatment increase is due to EPO
utilization.
 
     Patient Care Costs.  Patient care costs increased from $57.8 million for
the calendar year ended December 31, 1994 to $60.2 million for the calendar year
ended December 31, 1995, an increase of $2.4 million, or 4.2%. This increase was
due to the increase in the number of associated treatments, which caused a
corresponding increase in the use of drugs and supplies. Patient care costs as a
percentage of net revenue increased from 72.2% in 1994 to 72.8% in 1995. Average
patient care costs per treatment increased from $127 in 1994 to $129 in 1995, or
1.6%. This increase is due to normal health care inflation and higher than
expected EPO and other drug utilization costs.
 
     General and Administrative Expenses.  General and administrative expenses
increased from $7.8 million for the calendar year ended December 31, 1994 to
$8.1 million for the calendar year ended December 31,
 
                                       36
<PAGE>   40
 
1995, an increase of $300,000, or 3.8%. General and administrative expenses as a
percentage of net revenue remained constant at 9.8% in 1994 and 1995.
 
     Provision for Doubtful Accounts.  The provision for doubtful accounts
increased from $1.7 million for the calendar year ended December 31, 1994 to
$1.8 million for the calendar year ended December 31, 1995. Provision for
doubtful accounts as a percentage of net revenue remained constant at 2.2% in
1994 and 1995.
 
     Depreciation and Amortization.  Depreciation and amortization remained
unchanged at $2.1 million for the calendar year ended December 31, 1994 and the
calendar year ended December 31, 1995.
 
     Income from Operations.  Income from operations decreased from $10.6
million for the calendar year ended December 31, 1994 to $10.5 million for the
calendar year ended December 31, 1995, a decrease of $100,000, or 0.9%. Income
from operations as a percent of net revenue decreased from 13.2% in the 1994
period to 12.7% in the 1995 period. Income from operations decreased due to
increases in patient care costs in excess of net revenue, which was primarily
due to growth in health care inflation in excess of the growth of revenue per
treatment.
 
     Interest Income/Expense.  Interest expense increased from $317,000 for the
calendar year ended December 31, 1994 to $500,000 for the calendar year ended
December 31, 1995, a net increase of $183,000. This net increase can be
attributed to D.M.N. Professional Corporation's buy out of its hospital
partner's 50% interest in Northeast Indiana Kidney Center through the use of
commercial borrowings and the increase in working capital loans of the Founding
Companies from 1994 to 1995.
 
YEAR ENDED DECEMBER 31, 1994 COMPARED TO YEAR ENDED DECEMBER 31, 1993
 
     Net Revenue.  Net revenue increased from $72.6 million for the calendar
year ended December 31, 1993 to $80.0 million for the calendar year ended
December 31, 1994, an increase of $7.4 million, or 10.2%. This increase resulted
primarily from a 6.3% increase in the number of treatments from 427,270 in the
1993 period to 454,187 in the 1994 period and a 3.5% increase in the average
revenue per treatment from $170 in 1993 to $176 in 1994. The revenue per
treatment increase is due to an increase in higher revenue generating acute
treatments and greater than historical usage of EPO utilization.
 
     Patient Care Costs.  Patient care costs increased from $52.7 million for
the calendar year ended December 31, 1993 to $57.8 million for the calendar year
ended December 31, 1994, an increase of $5.1 million, or 9.7%. This increase is
due to the increase in the number of associated treatments, which caused a
corresponding increase in the use of labor, drugs and supplies. Patient care
costs as a percentage of net revenue decreased from 72.5% in the 1993 period to
72.2% in the 1994 period. Average patient care costs per treatment increased
3.3%, from $123 in 1993 to $127 in 1994. This increase is due to normal health
care inflation, higher than expected EPO costs and the increase in higher cost
acute treatments.
 
     General and Administrative Expenses.  General and administrative expenses
increased from $4.9 million for the calendar year ended December 31, 1993 to
$7.8 million for the calendar year ended December 31, 1994, an increase of $2.9
million, or 59%. General and administrative expenses increased as a percentage
of revenue by 46.3% in the 1994 period due primarily to management fees paid by
Main Line to its owners.
 
     Provision for Doubtful Accounts.  The provision for doubtful accounts
increased from $1.6 million for the calendar year ended December 31, 1993 to
$1.7 million for the calendar year ended December 31, 1994. The provision for
doubtful accounts as a percentage of net revenue remained constant at 2.2% in
1993 and 1994.
 
     Depreciation and Amortization.  Depreciation and amortization increased
from $2.0 million for the calendar year ended December 31, 1993 to $2.1 million
for the calendar year ended December 31, 1994, an increase of $100,000, or 5.0%.
This increase was due to the acquisition of patient care facilities in the
normal course of business.
 
     Income from Operations.  Income from operations decreased from $11.5
million for the calendar year ended December 31, 1993 to $10.6 million for the
calendar year ended December 31, 1994, a decrease of $900,000 or 7.8%. Income
from operations as a percent of net revenue decreased from 15.9% in the 1993
 
                                       37

period to 13.2% in the 1994 period. Income from operations decreased due to
increases in general and administrative costs in excess of net revenue, which
was primarily due to the payment of management fees by Main Line to its owners.
 
     Interest Expense.  Interest expense decreased from $371,000 for the
calendar year ended December 31, 1993 to $317,000 for the calendar year ended
December 31, 1994, a net decrease of $54,000. This net decrease was due to the
payoff of working capital loans in the normal course of business by the Founding
Companies.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     In February 1996, RCG completed its Offering of 4,485,000 shares of common
stock at $18.00 per share. The proceeds, net of underwriting discounts and
expenses of the offering were approximately $75,079,000. Concurrent with the
completion of the offering RCG paid approximately $39,699,000 to the
stockholders of the Founding Companies and issued 4,834,000 shares of its common
stock to such stockholders. In April 1996, RCG issued 528,000 shares of RCG
Common Stock as consideration in the acquisition by merger of Main Line and in
July 1996, RCG issued 298,775 shares of RCG Common Stock as consideration in the
acquisition by merger of The Nephrology Centers, Inc. At August 26, 1996,
10,146,136 shares of RCG Common Stock were outstanding.
    
 
     Working capital at June 30, 1996 was $35,370,000 and cash and cash
equivalents were $31,292,000. Net cash generated from operations during the six
months ended June 30, 1996 was $7,249,000.
 
     Capital expenditures for the six months ended June 30, 1996 were
$3,817,000. RCG repaid $9,021,000 in debt, including, $8,539,000 of debt that
was assumed from the Founding Companies. At June 30, 1996, RCG had $1,380,000 of
outstanding Convertible Senior Subordinated Promissory Notes due in December
1996 that are convertible into RCG Common Stock at $7.50 per share.
 
     RCG has a commitment from a bank to borrow up to $35.0 million to be used
for acquisitions, working capital and capital expenditures. This agreement was
put into place during the second quarter of 1996. Management believes that its
existing cash balances and cash generated from operations will be sufficient to
fund RCG's planned capital expenditures through the remainder of 1996.
 
IMPACT OF INFLATION
 
     A substantial portion of RCG's net revenue is subject to reimbursement
rates that are regulated by the federal government and do not automatically
adjust for inflation. RCG is unable to increase the amount it receives for the
services provided by its dialysis business that are reimbursed under the
Medicare composite rate. Increased operating costs that are subject to
inflation, such as labor and supply costs, without a compensating increase in
reimbursement rates, may adversely affect RCG's earnings in the future.

                                BUSINESS OF RCG
 
   
     Renal Care Group is a specialized provider of nephrology services that was
founded in June 1995 to focus on the provision of care to patients with kidney
disease, including patients suffering from chronic kidney failure. RCG provides
dialysis and ancillary services to approximately 3,280 patients through 51
outpatient dialysis centers in nine states, including five dialysis centers that
are managed but not owned by RCG, one of which is the dialysis program at
Vanderbilt University Medical Center. In addition to its outpatient dialysis
center operations, Renal Care Group provides acute dialysis services through
contractual relationships with 22 hospitals and physician practice management
services to nine of the 41 nephrologists who are affiliated with RCG's
outpatient dialysis centers.
    
 
     End-Stage Renal Disease ("ESRD") is the state of advanced renal impairment
that is irreversible and lethal unless treated. This condition is most commonly
a result of complications associated with diabetes, hypertension, certain renal
and hereditary diseases, old age and a combination of other risk factors. In
order to sustain life, individuals with ESRD require either dialysis for the
remainder of their lives or successful kidney transplantation. Currently, the
three treatment options for ESRD are (i) hemodialysis, which is performed either
in a hospital setting, an outpatient facility or a patient's home, (ii)
peritoneal dialysis, which is generally performed in the patient's home, and
(iii) kidney transplant surgery.
 
     Nephrologists provide ancillary services to ESRD patients, the most
significant of which is the administration of erythropoietin ("EPO"). EPO is a
bio-engineered protein that mimics a hormone found in a normal kidney by
stimulating the production of red blood cells. EPO is utilized in connection
with all forms of dialysis to treat anemia, a medical complication experienced
by almost all ESRD patients. EPO reduces or eliminates the need for blood
transfusions in these patients. Other ancillary services provided by
nephrologists to or in connection with ESRD patients may include but are not
limited to (i) certain laboratory tests required by Medicare to determine the
effectiveness of dialysis treatments, (ii) intra-dialytic parenteral nutrition
("IDPN"), which are nutrients added to a patient's blood during hemodialysis,
(iii) studies to test the degree of a patient's bone deterioration, an ESRD
complication, (iv) electrocardiograms, (v) nerve conduction studies to test for
deterioration of a patient's nerves, another ESRD complication, (vi) Doppler
flow testing for the effectiveness of the patient's vascular access for
dialysis, and (vii) blood transfusions.
 
   
     On February 12, 1996, RCG acquired, in separate transactions, the dialysis
and related business and certain related assets of (i) Kidney Care, Inc. ("KCI")
and Medical Enterprises, Ltd. ("MEL") (KCI and MEL collectively "Kidney Care"),
(ii) D.M.N. Professional Corporation ("DMN"), (iii) Tyler Nephrology Associates,
P.A. ("Tyler"), (iv) Kansas Nephrology Association ("Kansas"), and (v) Renal
Care Group, Inc., a Tennessee corporation ("Tennessee") (Kidney Care, DMN,
Tyler, Kansas and Tennessee collectively the "Founding Companies"). RCG acquired
these five dialysis and related businesses and assets in exchange for shares of
RCG Common Stock, cash, notes payable and the assumption of certain debt (the
"Combination").
    
 
     On February 12, 1996, RCG also successfully completed an initial public
offering of 3,900,000 shares of its RCG Common Stock, all of which were offered
by RCG (the "Offering"). On February 20, 1996, the underwriters completed the
exercise of the overallotment option granted by RCG in the Offering for an
additional 585,000 shares of RCG Common Stock. RCG used approximately $40
million of the approximately $74 million in net proceeds from the Offering to
fund the cash portion of the purchase price for the Founding Companies, to repay
certain assumed indebtedness.
 
     On April 26, 1996, RCG completed a merger with Main Line Suburban Dialysis,
Inc. ("Main Line"), and on July 1, 1996, RCG completed a merger with The
Nephrology Centers, Inc. ("TNC," and together with Main Line and the Founding
Companies, the "Subsidiaries"), each of which will be accounted for as a
pooling-of-interests (the "Recent Mergers"). Main Line, based in Wynnewood,
Pennsylvania, operates five dialysis centers serving approximately 350 patients
in the suburban Philadelphia area. TNC, based in Pensacola, Florida, operates
two dialysis centers, serving approximately 250 patients in the Pensacola and
Crestview, Florida areas. TNC has four additional satellite units under
construction which are scheduled to open by September 1996. RCG acquired these
companies in exchange for shares of RCG Common Stock and the assumption of
certain debt.

OPERATIONS
 
  Location, Capacity and Use of Facilities
 
     RCG operates 51 outpatient dialysis centers with 41 affiliated
nephrologists and 826 certified dialysis stations, including four centers
managed by RCG, one of which is at Vanderbilt and has four affiliated
nephrologists and 26 certified dialysis stations. As of June 30, 1996, 30 of the
centers are leased and 17 of the centers are owned by RCG. The centers contain
between four and 46 stations and are located in nine states. RCG also provides
inpatient dialysis services, pursuant to contracts, to 22 acute-care hospitals.
 
     RCG estimates that its centers were operating at approximately 63% of
capacity as of June 30, 1996 (based on the assumption that a dialysis center is
able to provide up to three treatments a day per station, six days a week).
Accordingly, RCG believes it may increase the number of dialysis treatments up
to its capacity without making additional capital expenditures.
 
  Operation of Facilities
 
     RCG's dialysis centers are designed to provide outpatient hemodialysis and
related services to ESRD patients in a convenient setting. A majority of RCG's
centers utilize volumetric dialysis equipment that accommodates high flux and
high efficiency dialysis treatments. In addition to dialysis stations, RCG's
centers generally contain a nurses' station, a patient waiting area, examination
rooms, a supply room, a water treatment space to purify water used in
hemodialysis treatments, a dialyzer reprocessing room, staff work areas,
offices, and a staff lounge. Many of RCG's centers also have a designated area
for training patients in home dialysis and also offer certain amenities for the
patients.
 
     In accordance with conditions for participation in the Medicare ESRD
program, each of RCG's centers is supervised by a qualified Medical Director.
Each center is managed by an administrator, typically a registered nurse, who is
responsible for the day-to-day operations of the center and its staff. The staff
of each center typically includes registered nurses, licensed practical or
vocational nurses, patient care technicians, social workers, registered
dietitians, a unit clerk, and biomedical equipment technicians. Each center is
staffed in a manner that allows the number of personnel to be adjusted according
to the number of patients receiving treatments.
 
  Home Dialysis
 
     All of RCG's centers offer various forms of peritoneal and home
hemodialysis, primarily CAPD or CCPD. As of June 30, 1996, approximately 13% of
the patients treated by RCG received home dialysis. RCG's home dialysis services
consist of providing equipment and supplies, training, patient monitoring and
follow-up assistance to patients who prefer and are able to receive dialysis
treatments in their homes. RCG intends to expand its home dialysis program,
which RCG believes is important to the development of a fully integrated
nephrology services company.
 
  Hospital Care
 
     Certain of RCG's centers provide dialysis services through contracts with
hospitals located within their respective service areas. Under these contracts,
these centers typically provide equipment, supplies and personnel required to
perform hemodialysis and peritoneal dialysis in connection with the hospital's
inpatient services. Such inpatient dialysis services are required for patients
with acute renal failure resulting from accidents, medical and surgical
complications, patients in the early stage of renal failure and ESRD patients
who require hospitalization for other reasons. The terms of these contracts are
individually negotiated and vary by contract. Currently, most of RCG's hospital
contracts specify predetermined fees per dialysis treatment, although RCG
believes that such fees may be subject to negotiation in the future as the
provision of health care services becomes increasingly influenced by managed
care and subject to capitated arrangements.

  University Division
 
   
     RCG currently manages the dialysis programs at Vanderbilt and the Cleveland
Clinic, provides home dialysis services for a group of patients at the
University of Arkansas and provides consulting services to the University of
Michigan Medical Center regarding its dialysis program. RCG intends to expand
its university management program and is currently in various stages of
discussions with a number of university-based dialysis programs. In addition,
RCG also intends to acquire or develop university-based dialysis centers. RCG
believes that its affiliation with leading nephrology groups will enhance its
ability to attract and maintain agreements to manage the dialysis programs of
university medical centers. Furthermore, RCG expects that affiliation with
university medical centers will provide increased patient census, including the
potential for the development of new centers and access to highly qualified
Medical Directors and outcomes research.
    
 
  Relationships with Referral Sources, Medical Directors
 
     A key factor in the success of a dialysis center is its relationship with
local nephrologists. An ESRD patient generally seeks treatment at a center where
the patient's nephrologist has practice privileges. Consequently, RCG relies on
its ability to attract and to meet the needs of referring nephrologists in order
to receive and gain new referrals.
 
     RCG has engaged qualified physicians to serve as Medical Directors for each
of its centers. Generally, the Medical Director is a practicing, board-eligible
or board-certified nephrologist. Each of RCG's Medical Directors provides
services pursuant to an independent contractor agreement between RCG and the
physician or his or her professional practice group. Medical Directors'
responsibilities primarily consist of the administration and monitoring of RCG's
patient care policies, including patient education, administration of dialysis
treatment, development and training programs and assessment of all patients.
Coordination of the delivery of care is important in maintaining ESRD patients'
general level of health and in avoiding medical complications that might
necessitate hospitalization.
 
   
     As part of the Combination, the former owners of the Founding Companies
(except Tennessee) who are nephrologists entered into Medical Director
agreements with RCG containing terms of seven years with three-year renewal
options. As part of the Main Line Merger, the former owners of Main Line who are
nephrologists entered into similar Medical Director agreements with RCG. In the
case of Kidney Care, which was not owned by the Medical Directors of its
centers, such Medical Directors continue to serve in that capacity at those
facilities under agreements that were assigned to RCG. RCG's Medical Director
agreements typically provide for its Medical Directors to be paid fees for their
supervisory services and include non-competition clauses with specific
limitations on their ability to compete with RCG for certain periods of time and
in certain geographic areas. In consideration for such non-competition
agreements, RCG has granted options to purchase shares of RCG Common Stock to
the physicians serving as Medical Directors or their professional practice
groups.
    
 
  Nephrology Practice Management
 
     RCG currently manages the practices of nine physician nephrologists
pursuant to the terms of management service arrangements. Under these
arrangements, RCG typically provides to the physicians, in exchange for a
management fee, certain equipment, supplies and certain administrative services,
including billing, collection, accounting, human resources, information systems
and contract negotiating services. Each physician retains exclusive control of
the provision of medical services to his or her patients.
 
QUALITY ASSURANCE, IMPROVEMENT OF PATIENT CARE
 
  Improvements of Clinical Protocols Through Research
 
     RCG believes that the provision of high quality care to ESRD patients
reduces the aggregate costs associated with ESRD by decreasing the number of
days an ESRD patient spends in the hospital. RCG believes that access to medical
research regarding causes and effects of ESRD, including causes and lengths of
hospitalization and resulting gross and standardized mortality rates, and
different types of treatment outcomes,
 
                                       41
<PAGE>   45
 
is crucial to the successful management of ESRD. RCG believes that its
affiliation with university-based dialysis programs provides it with access to
such outcomes research and to clinically advanced treatment protocols. For
example, according to data published by the USRDS, during 1992, the average
number of days spent in a hospital by dialysis patients less than 65 years of
age was 12.2, and for patients older than 65 years was 14.1. Similarly, the
USRDS calculated the overall mortality rate of dialysis patients during the
first year of therapy (starting in the 91st day after initiation of therapy) to
be 26.4% in 1992. Treatment protocols designed to address such issues as
adequacy of dialysis, nutrition, and management of hemodialysis access
complications can significantly improve mortality and decrease hospitalization
rates. RCG believes that the protocols it has implemented in the dialysis
program at Vanderbilt have been effective in maintaining an overall mortality
rate of approximately one-half of the national average and in reducing the
average hospitalization rate for all age groups to less than 10 days a year per
patient. RCG intends to implement its most clinically advanced protocols at all
of its centers, as well as at centers that may be acquired, and believes that
such implementation will optimize clinical management of patients and improve
operating efficiencies.
 
  Quality Assurance
 
     In order to optimize therapy and improve outcomes, RCG monitors patient
outcomes in all of its centers. Regular monitoring of the prescribed dialysis
treatments and the key physiological parameters of patients constitutes part of
the continuous quality improvement that is conducted as a matter of RCG policy.
 
     At the center level, pursuant to Medicare requirements, each center has a
quality assurance committee that typically includes the Medical Director, the
center administrator and nurses, as well as other technical personnel. This
committee meets regularly to monitor the quality of care in the center and to
assure compliance with applicable regulations.
 
     At the patient level, RCG attempts to ensure quality care through the
provision of instruction to all ESRD patients before and after the initiation of
dialytic therapy. Patients are encouraged to participate in their own care to
the fullest extent possible. In addition, in some of RCG's centers, "self-care"
units are formed in which self-reliance is fostered through-instruction and
support.
 
  Outcomes Data
 
     RCG believes that an important factor in the successful management of ESRD
is access to a broad database of treatment-specific outcomes information from
which clinical pathways may be defined. RCG has begun the collection of patient
outcomes and cost data which it believes will assist it in implementing clinical
pathways to enhance patient outcomes while reducing the cost of care. Management
believes that the implementation of such clinical pathways will allow it to
improve the overall quality and operating efficiencies of its dialysis centers
and to contract more effectively with payors in a health care environment
increasingly influenced by managed care.
 
  Medical Advisory Board
 
     RCG has established a Medical Advisory Board (the "MAB") that will meet
periodically to evaluate RCG's clinical protocols and review patient outcomes.
The MAB is chaired by Raymond Hakim, M.D., Ph.D., RCG's Chief Medical Officer,
and is composed of affiliated nephrologists, and is expected to include in the
future quality control and health care experts from outside RCG. The MAB's
principal tasks will include identifying therapy deficiencies, developing
solutions and reviewing technological changes. In addition, the MAB will be
responsible for establishing, implementing and monitoring RCG's quality
assurance policies and procedures.

     The Social Security Act (the "Act") provides for Medicare coverage for
certain individuals who are medically determined to have ESRD. Once an
individual is medically determined to have ESRD, the Act specifies that one of
two conditions must be met before entitlement begins: (i) a regular course of
dialysis must begin, or (ii) a kidney transplant must be performed. The Act
provides that entitlement begins the third month after the month in which a
regular course of renal dialysis is initiated. ESRD is currently defined in
federal regulations as that stage of kidney impairment that appears irreversible
and permanent and requires a regular course of dialysis or kidney
transplantation to maintain life.
 
     Under the Medicare ESRD program, the reimbursement rates per treatment are
fixed but have been adjusted from time to time by legislation. Although this
form of reimbursement limits the allowable charge per treatment, it provides RCG
with predictable and recurring per treatment revenue. The Medicare composite
rate, set by HCFA, governs the Medicare reimbursement available for a designated
group of dialysis services, including the dialysis treatment, supplies used for
such treatment, certain laboratory tests and medications. The Medicare composite
rate is subject to regional differences based on certain factors, including
regional differences in wages. Certain other services and drugs are eligible for
separate reimbursement under Medicare and are not part of the composite rate,
including certain drugs such as EPO and certain physician ordered tests provided
to dialysis patients. RCG generally submits Medicare claims monthly and is
usually paid within 30 days of the submission.
 
  Medicare Eligibility
 
     Set forth below are summaries of the general requirements for participation
in the Medicare ESRD program:
 
     - Medicare generally covers those who are ages 65 and over, as well as
      those who are under age 65 and who have been medically determined to have
      ESRD. However, Medicare coverage is secondary for some patients who have
      qualifying employer group health insurance.
 
     - For patients eligible for Medicare based solely on ESRD (generally, those
      under age 65), Medicare coverage begins three months after the month in
      which the patient begins dialysis. During this three-month waiting period,
      Medicaid (if the patient is eligible), private insurance, or the patient
      is responsible for payment for dialysis services. This waiting period is
      waived for individuals who participate in a self-care dialysis training
      program.
 
     - For ESRD patients under age 65 who have any employer group health
      insurance coverage (regardless of the size of the employer or the
      individual's employment status), Medicare coverage is secondary to the
      employer coverage during the 18-month period following the establishment
      of Medicare eligibility based on ESRD. Medicare continues to be secondary
      regardless of whether the individual becomes eligible for Medicare based
      on age or disability before the expiration of the 18 months.
 
     - During the period of secondary coverage, the employer group health plan
      is responsible for paying primary benefits at its negotiated rate or, in
      the absence of such a rate, at RCG's usual and customary
 
                                       43
<PAGE>   47
 
      rates. Medicare generally pays the difference between what the employer
      group health plan paid and the gross amount payable by Medicare.
 
     - For patients over ages 65 for whom Medicare already is the primary payor
      and who later develop ESRD, Medicare remains the primary payor. (Some
      group health coverage does not render Medicare coverage secondary for
      beneficiaries eligible for Medicare based on age or disability.) However,
      if the patient's employer group health coverage already was primary to
      Medicare (based on the size of the employer and the patient's employment
      status), then Medicare remains secondary for the 18-month period.
 
     - When Medicare is the primary payor, it reimburses 80% of the amount set
      by the Medicare prospective reimbursement system for each treatment. The
      beneficiary is responsible for the remaining 20%, as well as any unmet
      Medicare deductible amount, although Medicare supplemental insurance,
      Medicaid, or other private health insurance may pay on the beneficiary's
      behalf.
 
     Following amendments in 1993 to the Medicare Secondary Payor ("MSP")
provisions, HCFA required employer group health plans to serve as the primary
payor during the 18-month period in situations where the beneficiary was
entitled to Medicare Benefits on the basis of both age and ESRD. On April 24,
1995, HCFA revised its interpretation of the 1993 MSP amendments to require
Medicare to serve as primary payor for the 18 month period only where employer
coverage was already secondary to Medicare for individuals eligible for Medicare
benefits on the basis of both age and ESRD. This change eliminates for some
dually-eligible individuals the 18-month period commencing 90 days after the
start of treatment during which the employer coverage would serve as primary
payor source and reimburse RCG at a rate that RCG believes is higher than
Medicare. Furthermore, HCFA also announced that the revised interpretation would
apply retroactively to August 10, 1993 and, as a result, amounts collected from
employer-based group health plans as primary payors between August 10, 1993 and
April 24, 1995 were to be refunded if the plan was not already serving as
primary payor. On June 5, 1995, the United States District Court for the
District of Columbia issued a preliminary injunction prohibiting HCFA from
applying this revised interpretation retroactively to August 10, 1993, although
a final ruling on the issue has not yet been issued by the court. RCG has
established reserves for the retroactive application of the revised HCFA
interpretation and believes that the amount of such reserves is adequate.

     The Medicare composite rate for outpatient dialysis services currently
averages $126 per treatment and may vary depending on regional wage differences.
Medicare reimbursement rates are adjusted periodically based on certain factors,
including legislation and executive and congressional budget reduction and
control processes, inflation and costs incurred in rendering the services, but
in the past have had little relationship to the cost of conducting business.
 
     The Medicare ESRD composite reimbursement rate was unchanged from
commencement of the program in 1972 until 1983. From 1983 through December 1990,
numerous Congressional actions resulted in net reductions of the average
composite reimbursement rate from a fixed fee of $138 per treatment in 1983 to
approximately $125 per treatment in 1986. Congress increased the ESRD composite
reimbursement rate, effective January 1, 1991, resulting in an average rate of
$126 per treatment.
 
     The Medicare ESRD composite reimbursement rate has been the subject of a
number of reports and studies. In April 1991, the Institute of Medicine, an
organization chartered by the National Academy of Sciences and an advisor to the
federal government, released a report recommending that the composite rate be
adjusted for the effects of inflation. In March 1995, after conducting a study
on dialysis costs and reimbursement at the request of Congress, the Prospective
Payment Assessment Commission ("PROPAC") recommended no changes be made in the
ESRD composite reimbursement rate. Congress is not required to implement either
of these recommendations and could either raise or lower the reimbursement rate.
Furthermore, as part of the deliberations in Congress over the 1996 federal
budget, there were various proposals for the reform of numerous aspects of
Medicare. RCG is unable to predict what, if any, future
 
                                       44
<PAGE>   48
 
changes may occur in the Medicare composite reimbursement rate. Any reductions
in the Medicare composite reimbursement rate could have a material adverse
effect on RCG's revenues and net earnings.
 
     From June 1, 1989 through December 31, 1990, the Medicare ESRD program
added $40 per administration of EPO to the dialysis center's allowable composite
rate for dosages of up to 9,999 units per administration. For higher dosages, an
additional $30 per treatment was allowed. Effective January 1, 1991, the
Medicare allowable prescribed rate for EPO was changed to $11 per 1,000 units,
rounded to the nearest 100 units. Subsequently, legislation was enacted to
reduce the Medicare prescribed rate for EPO by $1 to $10 per 1,000 units for
administration of EPO in 1994. For subsequent periods, the Secretary of the
Department of Health and Human Services ("HHS") is authorized to determine an
appropriate rate, which currently is $10 per 1,000 units administered.
 
  Medicaid Reimbursement
 
     Medicaid programs are state administered programs partially funded by the
federal government. These programs are intended to provide coverage for patients
whose income and assets fall below state defined levels and who are otherwise
uninsured. The programs also serve as supplemental insurance programs for the
Medicare co-insurance portion and provide certain coverages (e.g., oral
medications) that are not covered by Medicare. State regulations generally
follow Medicare reimbursement levels and coverages without any coinsurance
amounts. Certain states, however, require beneficiaries to pay a monthly share
of the cost based upon levels of income or assets. RCG is a licensed ESRD
Medicaid provider in all states in which it does business.
 
  Private Reimbursement/Acute Care Contracts
 
     RCG receives reimbursement from private payors for ESRD treatments prior to
Medicare becoming a patient's primary payor at rates significantly higher than
the per treatment rate set by Medicare. After Medicare becomes a patient's
primary payor, private secondary payors generally reimburse RCG for 20% of the
Medicare per treatment rate. RCG has negotiated managed care contracts with
certain payors at rates that are higher than the Medicare rate. RCG also
receives payments from hospitals under 21 acute care contracts at rates
significantly higher than the Medicare composite rate.
 
GOVERNMENT REGULATION
 
  General
 
     RCG's dialysis center operations are subject to extensive governmental
regulation at the federal, state and local levels. These regulations require RCG
to meet various standards relating to, among other things, the management of
centers, personnel, maintenance of proper records, equipment and quality
assurance programs. The dialysis centers are subject to periodic inspection by
state agencies and other governmental authorities to determine if the premises,
equipment, personnel and patient care meet applicable standards. To receive
Medicare reimbursement, RCG's dialysis centers must be certified by HCFA. All of
RCG's dialysis centers are so certified.
 
     Any loss by RCG of its federal certifications, its authorization to
participate in the Medicare or Medicaid programs or its licenses under the laws
of any state or other governmental authority from which a substantial portion of
its revenues is derived or a change resulting from health care reform reducing
dialysis reimbursement or reducing or eliminating coverage for dialysis services
would have a material adverse effect on RCG's operations, revenues and net
earnings. To date, the Subsidiaries have maintained their licenses and their
Medicare and Medicaid authorizations. RCG believes that the health care services
industry will continue to be subject to intense regulation at the federal, state
and local levels, the scope and effect of which cannot be predicted. No
assurance can be given that the activities of RCG will not be reviewed and
challenged by government regulators or that health care reform will not result
in a material adverse change to RCG.
 
     Furthermore, RCG potentially could be held responsible for actions
previously taken by the RenalWest Parties. As part of its announced regulatory
agenda for 1996, HHS intends to issue a proposed rule that would
 
                                       45
<PAGE>   49
 
automatically assign to the new owner of a Medicare provider or supplier
liability for any Medicare overpayments, violations, or sanctions incurred by or
imposed on, the previous owner. There can be no assurance that previous
operating practices of the RenalWest Parties will not be reviewed and challenged
by government regulators or that RCG will not be liable for such practices.
 
  Fraud and Abuse
 
     RCG's operations are subject to the illegal remuneration provisions of the
Social Security Act (sometimes referred to as the "anti-kickback" statute) and
similar state laws that impose criminal and civil sanctions on persons who
knowingly and willfully solicit, offer, receive or pay any remuneration, whether
directly or indirectly, in return for, or to induce, the referral of a patient
for treatment, or, among other things, the ordering, purchasing, or leasing, of
items or services that may be paid for in whole or in part by Medicare, Medicaid
or similar state programs. At the closing of the Combination and the Recent
Mergers, shares of Common Stock were issued to certain nephrologist owners of
the Subsidiaries. In addition, pursuant to the terms of RCG's agreements with
its Medical Directors or their professional practice groups, RCG pays fees for
medical director services and has granted options to purchase shares of RCG
Common Stock to individual Medical Directors or their respective practice
groups. Because these physicians refer to RCG's centers, the federal
anti-kickback statute could be found to apply to referrals by nephrologists to
RCG's facilities. However, RCG believes these ownership relationships are in
material compliance with the federal anti-kickback statute. Also, RCG believes
that the value of RCG Common Stock issued and options granted to nephrologists
have and will be consistent with the fair market value of assets transferred to,
or services performed by such nephrologists for, RCG and there is no intent to
induce referrals to RCG's facilities. There is a safe harbor for certain
investments in large public companies, and RCG believes that there are good
arguments that its physician ownership relationships meet at least a majority of
the criteria for this safe harbor. However, these relationships do not satisfy
all of the criteria of a safe harbor and there can be no assurance that these
relationships will not subject RCG to investigation or prosecution by
enforcement agencies. RCG believes that the RenalWest Parties' arrangements and
RCG's current arrangements with nephrologist owners, medical directors,
laboratories, IDPN suppliers, hospitals, and other persons or entities who
either refer patients to RCG's dialysis centers or from whom RCG purchases items
or services generally are, and that comparable future arrangements of RCG will
be, in material compliance with the federal anti-kickback statute.
 
  Stark II
 
     Provisions of the Omnibus Budget Reconciliation Act of 1993 ("Stark II")
prohibits physician referrals for certain "designated health services" to
entities with which a physician or an immediate family member has a "financial
relationship." While dialysis is not a designated health service under Stark II,
the definition of "designated health services" includes items and services that
are components of dialysis or that may be provided to a patient in connection
with dialysis, if such items are considered separately rather than collectively
as dialysis. Because of its broad language, Stark II may be interpreted by HHS
to apply to certain of RCG's operations or the Merger. Under the final
regulations for the Omnibus Budget Reconciliation Act of 1989 ("Stark I")
published in August 1995, HCFA provided an exception from Stark I for clinical
laboratory services reimbursed under the Medicare "composite rate" for dialysis.
RCG believes it likely that, when final Stark II regulations are published, they
will contain a similar exception for "designated health services" billed under
the composite rate. However, there can be no assurance that HCFA will adopt such
a position, and if such a position is taken, the Company's provision of, or
arrangement and assumption of financial responsibility for, services and items
that are reimbursed separate from the Medicare composite rate are likely to be
construed to be "designated health services" within the meaning of Stark II.
 
     Consequently, Stark II may require RCG to restructure certain existing
compensation agreements with its Medical Directors or, in the alternative, to
refuse to accept referrals for designated health services from such physicians.
Moreover, since Stark II prohibits Medicare or Medicaid reimbursement of items
or services provided pursuant to a prohibited referral, and imposes substantial
civil monetary penalties on entities which present or cause to be presented
claims for reimbursement in such cases, RCG could be required to repay
 
                                       46
<PAGE>   50
 
amounts reimbursed for items and services that HCFA determines to have been
furnished in violation of Stark II, and could be subject to substantial civil
monetary penalties, either or both of which could have a material adverse effect
on RCG's operations, net revenue or earnings. RCG believes that if Stark II is
interpreted to apply to RCG's operations or the Merger, RCG will be able on a
prospective basis to bring its financial relationships with referring physicians
into material compliance with the provisions of Stark II, including relevant
exceptions, although prospective compliance would not affect amounts or
penalties determined to be owed for past conduct, and there can be no assurance
that such prospective compliance, if possible, will not have a material adverse
effect on RCG's operations, net revenue or earnings. If Stark II is interpreted
by HHS to apply to RCG or the Merger and RCG is determined to be liable for past
violations of Stark II by itself or one or more of the Subsidiaries or the
RenalWest Parties, the application of Stark II could have a material adverse
effect on RCG.
 
COMPETITION
 
     The dialysis industry is fragmented and highly competitive. Competition for
qualified physicians to act as Medical Directors is also high. According to the
USRDS, there were in excess of 2,500 dialysis centers in the United States at
the end of 1993. Based on published reports, RCG believes that approximately 35%
were owned by independent physicians, 29% were hospital-based, and 36% were
owned by six major multicenter dialysis providers, the largest of which is
National Medical Care, Inc. ("NMC"), a wholly-owned subsidiary of W.R. Grace &
Co. Certain of RCG's competitors have substantially greater financial resources
than RCG and may compete with RCG for acquisitions, development and/or
management of dialysis centers and nephrology practices. RCG believes that
competition for acquisitions has increased the cost of acquiring dialysis
centers and will likely increase the cost of acquiring nephrology practices. RCG
may also experience competition from centers established by former Medical
Directors or other referring physicians. There can be no assurance that RCG will
be able to compete effectively with any such competitors.
 
PROPERTIES
 
   
     Excluding the five managed centers, RCG operates 46 dialysis centers, of
which 30 are located in leased facilities, and 16 are owned. RCG's facilities
are located in Arkansas, Indiana, Kansas, Louisiana, Mississippi, Ohio,
Pennsylvania, Tennessee and Texas. Certain of the leased premises are leased
from former owners of Founding Companies. RCG's leases generally have terms
ranging from one to fifteen years and typically contain renewal options. The
sizes of RCG's centers range from approximately 400 to 17,000 square feet. RCG
leases office space in Nashville, Tennessee for its University division and
corporate headquarters under leases that expire in 1999 and 2002. RCG considers
its physical properties to be in good operating condition and suitable for the
purposes for which they are being used.
    
 
     Expansion or relocation of RCG's dialysis centers would be subject to
compliance with conditions relating to participation in the Medicare ESRD
program. In states that require a CON, approval of an application submitted by
RCG would be necessary for expansion or development of a new dialysis center.
 
     RCG generally owns the equipment used in its outpatient centers. RCG
considers its equipment to generally be in good operating condition and suitable
for the purposes for which it is being used.
 
LEGAL PROCEEDINGS
 
     RCG is subject to claims and suits in the ordinary course of business,
including those arising from patient treatment, which RCG believes will be
covered by malpractice insurance. RCG is not currently a party to any material
legal actions. However, certain of the Founding Companies are parties to
litigation that RCG did not assume and is indemnified against, subject to
certain limitations, by the Founding Companies and their owners pursuant to the
Combination agreements.

(1) The potential realizable value through the expiration date of the options
     has been determined on the basis of the Offering price of $18.00 per share
     compounded annually over the term of the option, net of the exercise price.
     These values have been determined based upon assumed rates of appreciation
     mandated by the Securities and Exchange Commission and are not intended to
     forecast the possible future appreciation, if any, of the price or value of
     the RCG Common Stock.
(2) The number of options granted to all employees in 1995 includes options to
     purchase 673,948 shares of RCG Common Stock, but does not include options
     to purchase 115,500 shares of the Common Stock of Tennessee that were
     assumed by the Company upon the closing of the Offering on a
     share-for-share basis.
(3) Does not include warrants to purchase 90,000 shares of the common stock of
     Tennessee granted in February 1994 at a price of $10.00 per share that were
     assumed by RCG on a share-for-share basis but with an exercise price of
     $7.50 per share.
(4) In the event of certain changes in control of RCG and the termination of the
     employment of the optionee, or in the event of certain changes in control
     of RCG that result in the RCG Common Stock or stock of a successor not
     being traded on a national securities market, these options may accelerate

(5) Does not include the following options to purchase shares of the common
     stock of Tennessee granted in April 1994, that were assumed by RCG on a
     share-for-share basis: 30,000 shares at an exercise price of $7.50 per
     share; 25,000 shares at an exercise price of $6.00 per share; 20,000 shares
     at an exercise price of $3.50 per share; and 10,000 shares at an exercise
     price of $2.00 per share.
(6) Option was exercisable as to twenty percent (20%) of these shares as of the
     grant date, and an additional twenty percent (20%) will vest on each of the
     first four anniversaries of the Offering.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     The members of RCG's Compensation Committee are Joseph C. Hutts, Steven D.
McMurray, M.D., and W. Tom Meredith, M.D. Mr. Brooks, the Chief Executive
Officer, President and a Director of RCG, is a member of the board of directors
of PhyCor, Inc., of which Mr. Hutts is the Chairman of the Board, President and
Chief Executive Officer.
 
EMPLOYMENT AGREEMENTS
 
     RCG has entered into or assumed employment and non-competition agreements
with its principal executive officers, including Mr. Brooks, Mr. Hinds, Dr.
Hakim and Mr. Cashia, and with certain of the principal operating officers of
each Founding Company. RCG has not and does not expect to enter into an
employment agreement with Dr. Jacobson, the Chairman of the Board, because he
does not devote his full time and attention to the affairs of RCG. Each Named
Executive Officer's employment agreement contains restrictive covenants
prohibiting such officer from competing with RCG for a period of one year after
the end of the employment term. The terms of the employment agreements commenced
on February 12, 1996 and will continue for a term of three years and successive
one year renewal terms thereafter, except for Mr. Cashia's which was assumed by
RCG on February 12, 1996 and expires March 31, 1997.
 
     The annual salaries of the Named Executive Officers as set forth in the
employment agreements are $250,000, $182,500, $184,000 and $200,000 for Messrs.
Brooks, Hinds and Cashia, and Dr. Hakim, respectively. Each Named Executive
Officer is eligible under his employment agreement for bonuses at the sole
discretion of RCG (up to a maximum, in Mr. Cashia's agreement, of $50,000).
 
     The employment agreements of Messrs. Brooks and Hinds, and Dr. Hakim, also
provide for severance for each such Named Executive Officer of (i) his salary
for 12 months if such officer is terminated without cause, (ii) his salary for
one month if such officer is terminated for cause, or (iii) his salary for 36
months is such officer is terminated within 12 months of certain changes in
control of RCG either (A) without cause, or (B) by resignation of the officer
himself from a decline reassignment of a job that is not the equivalent of his
then current position (in responsibility, compensation or geographic area of
service).
 
     In addition to the above provisions, Mr. Brooks' employment agreement also
provides for (i) life insurance coverage of $2,000,000, (ii) long term
disability insurance of 60% of Mr. Brooks' annual base salary, (iii) an annual
bonus of 75% of his annual base salary to be earned if RCG meets or exceeds its
earning per share projections as approved by the Compensation Committee, (iv) a
$100,000 payment for efforts related to the Offering, payable out of the
proceeds of the Offering, and (v) severance as provided above but based upon his
salary plus his prior year's bonus instead of just his salary.
 
     RCG assumed the employment agreement between Tennessee and Mr. Cashia dated
April 4, 1994. Mr. Cashia's agreement provides for severance of his salary for
12 months and the amount of any bonus paid to Mr. Cashia in the prior year, and
medical coverage for himself and his family if he is terminated without cause
(as defined in his agreement).

STOCK OPTION AND STOCK PURCHASE PLANS
 
  1996 Stock Option Plan
 
   
     In January 1996, RCG adopted the Renal Care Group, Inc. 1996 Stock Option
Plan (the "Option Plan"). See "Proposal II -- Approval of Proposed Amendment to
the 1996 Stock Option Plan" for a description of the terms of the Option Plan
and the proposed Amendment thereto.
    
 
  1996 Stock Option Plan for Outside Directors
 
     In January 1996, RCG adopted the Director Plan and reserved 100,000 shares
of RCG Common Stock for issuance to non-employee directors of RCG thereunder.
The Director Plan provides for grants of options to purchase 2,500 shares of RCG
Common Stock to "outside directors" who have been directors for at least six
months on the day after each annual meeting of stockholders of RCG, and for
grants of options to purchase 5,000 shares of RCG Common Stock to "outside
directors" on the day such persons first become directors of RCG. For purposes
of the Director Plan, "outside director" means any non-employee director who is
not the Chairman or Vice Chairman of the Board and who also is not a party to,
and whose medical practice is not a party to, a then currently effective Medical
Director Agreement with RCG. The option price for each option granted under the
Director Plan will be equal to 100% of the fair market value on the date of
grant. An option under the Director Plan will be immediately exercisable and
will remain exercisable for ten years from the date of grant. In the event of a
change of control of RCG (as defined in the Director Plan) that results in the
RCG Common Stock or the stock of any successor to RCG ceasing to be publicly
traded in a national securities market, the Director Plan requires that RCG or
its successor must "cash out" such options by paying the director an amount for
each share subject to such options equal to the difference of the highest
closing price per share of RCG Common Stock during the ninety day period ending
on the date of the change in control of RCG, minus the exercise price.
 
  Employee Stock Purchase Plan
 
     The Renal Care Group, Inc. Employee Stock Purchase Plan (the "Purchase
Plan") was adopted in January 1996. A total of 300,000 shares of RCG Common
Stock have been reserved for issuance under the Purchase Plan, which is intended
to qualify under Section 423 of the Code. The Purchase Plan allows participants
to purchase shares of RCG Common Stock in connection with option periods
commencing July 1 and ending the following June 30 (except the first option
period which commenced the date of the Offering and ended June 30, 1996).
 
     The Purchase Plan permits eligible employees of RCG and certain of its
subsidiaries to purchase RCG Common Stock through payroll deductions, which may
not exceed 10% of the employee's base compensation, at a price equal to 85% of
the fair market value of the RCG Common Stock at the beginning of the option
period or at the end of the option period, whichever is lower (subject to a
minimum price specified in the Purchase Plan).
 
     In the event of a change of control of RCG (as defined in the Purchase
Plan), each option under the Purchase Plan will (if RCG is the surviving
corporation) pertain to and apply to the securities to which a holder of the
number of shares of RCG subject to such option would have been entitled in such
transaction. If RCG is not the surviving corporation in such change of control,
then all options under the Purchase Plan will terminate provided that the
Compensation Committee may determine that such options shall be exercisable on
the day prior to such change in control transaction.

                 RENALWEST MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
SIX MONTHS ENDED JUNE 30, 1996 COMPARED TO SIX MONTHS ENDED JUNE 30, 1995
 
     Net Revenue.  Net revenue increased $1.1 million to $17.4 million for the
six months ended June 30, 1996 compared to $16.3 million for the six months
ended June 30, 1995, representing a 6.7% increase. The increase is due primarily
to an increase in treatments of 7,422 or 9.4% to 86,172 for the six months ended
June 30, 1996 from 78,750 for the six months ended June 30, 1995. For the six
months ended June 30, 1996, net revenue on a per treatment basis was $202
compared to $207 for the six months ended June 30, 1995. The decrease in net
revenue per treatment is primarily due to a decrease in administration of EPO to
$33 per treatment in 1996 from $38 in 1995.
 
   
     Patient Care Costs.  Patient care costs increased $1.6 million to $10.8
million for the six months ended June 30, 1996 from $9.2 million for the six
months ended June 30, 1995. The increase is due to an increase in treatments of
7,422 or 9.4%, to 86,172 for the six months ended June 30, 1996 from 78,750 for
the six months ended June 30, 1995. On a per treatment basis, patient care costs
increased $9.00 to $125 for the six months ended June 30, 1996 from $116 for the
six months ended June 30, 1995. The increase is due to increased labor costs
resulting from the training involved in computerizing its clinics as well as
general inflationary increases.
    
 
     General and Administrative Expenses.  General and administrative expenses
decreased $300,000 or 10.5% from $3.1 million for the six months ended June 30,
1995 to $2.8 million for the six months ended June 30, 1996. This decrease was
due primarily to a reduction in compensation expense recognized during 1995 for
the admission of new members into RenalWest. General and administrative expenses
as a percentage of net revenue decreased from 19.1% in 1995 to 16.0% in 1996.
General and administrative expenses decreased as a percentage of revenue for the
1996 period because of the increase in revenue without incurring additional
general and administrative expenses.
 
     Provision for Doubtful Accounts.  The provision for doubtful accounts
decreased approximately $1.3 million to $313,000 for the six months ended June
30, 1996 from $1.6 million for the six months ended June 30, 1995. As a
percentage of net revenue, the provision for doubtful accounts decreased to 1.8%
for the six months ended June 30, 1996 from 10.1% for the six months ended June
30, 1995. During the six months ended June 30, 1995, management changed its
estimation of the collectability of certain older accounts resulting in an
increase to the provision for doubtful accounts of $1.3 million. No such
increase was necessary for the six months ended June 30, 1996.
 
     Depreciation and Amortization.  Depreciation and amortization increased
$334,000 or 53.7% to $955,000 for the six months ended June 30, 1996 from
$621,000 for the six months ended June 30, 1995. This increase was attributable
to depreciation on the clinical computer system purchased in 1996 and
amortization from new center leasehold improvements and routine capital
expenditures.
 
     Income from Operations.  Income from operations increased $900,000 to $2.6
million for the six months ended June 30, 1996 from $1.7 million for the six
months ended June 30, 1995 As a percentage of net revenues, income from
operations increased to 14.8% for the six months ended June 30, 1996 from 10.7%
for the six months ended June 30, 1995. The increase in income from operations
is due primarily to the decrease in the provision for doubtful accounts offset
by increased depreciation and amortization.
 
     Interest Expense, net.  Interest expense, net increased $58,000 or 28.4% to
$262,000 for the six months ended June 30, 1996 from $204,000 for the six months
ended June 30, 1995. As a percentage of net revenue, interest expense, net
increased to 1.5% for the six months ended June 30, 1996 from 1.3% for the six
months ended June 30, 1995. Interest expense, net increased due to the financing
of the clinical computer system purchased in 1996, leasehold improvements and
routine capital expenditures as well as increased short-term borrowings on the
revolving line of credit.

<PAGE>   56
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
     Net Revenue.  Net revenue increased $1,343,000 to $32.0 million for the
year ended December 31, 1995 from $30.7 million for year ended December 31, 1994
representing a 4.2% increase. The increase is due primarily to an increase in
treatments of 13,957 or 9.7%, to 158,044 in the year ended December 31, 1995,
from 144,087 in the year ended December 31, 1994. For the year ended December
31, 1995, net revenue on a per treatment basis was $203 compared to $213 for the
year ended December 31, 1994. The decrease in net revenue per treatment is
primarily due to an increase in the percentage of Medicare patients as Medicare
pays lower rates, a reduction in the number of and average charge for acute
treatments, a reduction in the amount of EPO used per treatment, a shift of
peritoneal dialysis patients to a lower reimbursement and the discontinuation of
a certain diagnostic test.
 
     Patient Care Costs.  Patient care costs increased $1.4 million to $19.0
million in the year ended December 31, 1995 from $17.6 million in the year ended
December 31, 1994. The increase is due primarily to an increase in treatments of
13,957 to 158,044 in the year ended December 31, 1995 from 144,087 in the year
ended December 31, 1994. On a per treatment basis, patient care costs decreased
to $121 in the year ended December 31, 1995 from $122 in the year ended December
31, 1994. The decrease in primarily due to a decrease in EPO usage per treatment
and a reduction in labor costs per treatment.
 
     General and Administrative Expenses.  General and administrative expenses
increased $1.3 million or 27.1% from $4.8 million for the year ended December
31, 1994 to $6.1 million for the year ended December 31, 1995. General and
administrative expenses as a percentage of net revenue increased from 15.5% in
1994 to 18.6% in 1995. General and administrative expenses increased in 1995 due
to costs related to the remaining rent payments on a dialysis facility that was
vacated, the addition of new management positions to prepare for managed care,
and increases in salary for certain administrative personnel.
 
     Provision for Doubtful Accounts.  The provision for doubtful accounts
increased $900,000 to $2.1 million for the year ended December 31, 1995 from
$1.2 million for the year ended December 31, 1994. As a percentage of net
revenue, the provision for doubtful accounts increased to 6.7% for the year
ended December 31, 1995 from 3.9% in the year ended December 31, 1994. This
increase was attributable to a change in management's estimation of the
collectability of certain older accounts.
 
     Depreciation and Amortization.  Depreciation and amortization increased
$100,000 or 7.7% to $1.4 million for the year ended December 31, 1995 from $1.3
million for the year ended December 31, 1994. As a percentage of net revenue,
depreciation and amortization increased to 4.4% in the year ended December 31,
1995 from 4.3% in the year ended December 31, 1994. This increase was
attributable to increased amortization from new center leasehold improvements
and routine capital expenditures.
 
     Income from Operations.  Income from operations decreased $2.4 million to
$3.4 million for the year ended December 31, 1995 from $5.8 million for the year
ended December 31, 1994. As a percentage of net operating revenues, income from
operations decreased to 10.7% for the year ended December 31, 1995 from 18.9%
for the year ended December 31, 1994. The decrease in income from operations is
due primarily to the increase in general and administrative expenses and the
provision for doubtful accounts.
 
     Interest Expense, net.  Interest expense, net increased $80,000 or 24.2% to
409,000 for the year ended December 31, 1995 from $329,000 for the year ended
December 31, 1994. As a percentage of net revenue, interest expense, net
increased to 1.3% in the year ended December 31, 1995 from 1.1% in the year
ended December 31, 1994. Interest expense, net increased due to higher average
interest rates in 1995 over 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Net cash provided by operating activities was $3.5 million for the six
months ended June 30, 1996 and $8.4 million for the year ended December 31,
1995. Cash used for investing activities included capital expenditures of $1.2
million for the six months ended June 30, 1996 and $4.7 million for the year
ended December 31, 1995. Net borrowing from bank loans and lines of credit was
reduced by $588,000 for the six months ended June 30, 1996 compared to the
corresponding period in 1995, and increased by $602,000 for the year ended
December 31, 1995 over the prior year.

     RenalWest has commitments from a commercial bank to lend up to $2,000,000
for equipment financing through May 28, 1997 and to provide a revolving line of
credit of $1,500,000. As of June 30, 1996, RenalWest had borrowed $368,000 under
the equipment line and had $329,000 outstanding under the revolving line of
credit. Management believes that its existing cash balances, available bank
commitments and cash generated from operations will be sufficient to fund
RenalWest's planned capital expenditures and operating expenses through the
remainder of 1996.

                             BUSINESS OF RENALWEST
 
   
     RenalWest, L.C. ("RenalWest") is the largest provider of kidney dialysis
services in the state of Arizona. RenalWest provides dialysis and ancillary
services to approximately 1,200 patients through 19 freestanding outpatient
hemodialysis centers and 3 home peritonealdialysis centers throughout Arizona.
RenalWest also provides acute dialysis services through contractual
relationships with 16 hospitals and staff-assisted dialysis services to 37
skilled nursing facilities. RenalWest was founded in 1993 through the
combination of 14 separate dialysis facilities.
    
 
OPERATIONS
 
  Locations, Capacity and Use of Facilities
 
   
     RenalWest operates 19 freestanding outpatient hemodialysis centers and
three home peritonealdialysis centers with 18 affiliated nephrologists and 285
certified dialysis stations in the state of Arizona. RenalWest's centers contain
between 9 and 21 dialysis stations. RenalWest also provides inpatient dialysis
services, pursuant to contracts, with 16 acute-care hospitals and staff-assisted
dialysis services and 37 skilled nursing facilities.
    
 
     RenalWest estimates that its centers are operating at approximately 68% of
capacity as of July 1996 (based on the assumption that a dialysis center is able
to provide up to three treatments per day per station, six days a week).
Accordingly, RenalWest believes it may increase the number of dialysis
treatments up to its capacity without making additional capital expenditures in
the existing centers.
 
  Operation of Facilities
 
   
     RenalWest's dialysis centers are designed to provide outpatient
hemodialysis and related services, and home training and support services to
ESRD patients in a convenient setting and location. All of RenalWest's centers
utilize volumetric dialysis equipment that accommodate high flux and high
efficiency dialysis treatments. In addition to dialysis stations, RenalWest's
centers generally contain a nurses' station, a patient waiting area, examination
room, supply room, water treatment space to purify water used in hemodialysis
treatments, a dialyzer reprocessing room, staff work areas, offices, and a staff
lounge. Three of RenalWest's centers are solely designed for the training,
ongoing support and clinic visits for the home dialysis patients. These centers
also contain a patient waiting area, supply room, staff work areas, offices, a
staff lounge and certain amenities that enhance the learning environment for
patients.
    
 
     In accordance with conditions for participation in the Medicare ESRD
program, each of RenalWest's centers is supervised by a qualified Medical
Director. Each center is managed by an Clinical Manager (a registered nurse),
who is responsible for the day-to-day operations of the center and its staff.
The staff of each center typically includes registered nurses, licensed
practical nurses, patient care technicians, operations specialists, a social
worker, a dietitian, a unit secretary, and biomedical equipment support. Each
center is staffed in a manner that allows the number of personnel to be adjusted
according to the number of patients receiving treatments.
 
  Home Dialysis
 
     Three of RenalWest's centers offer various forms of peritoneal and home
hemodialysis, primarily CAPD or CCPD. These centers are solely designed for the
training, ongoing support and clinic visits for home dialysis patients. During
the year ended December 31, 1995, approximately 19% of the patients treated by
RenalWest received home dialysis. RenalWest's home dialysis services consist of
providing equipment and supplies, training, patient monitoring and followup
assistance to patients who prefer and are able to receive dialysis treatments in
their homes.
 
  Hospital Care
 
     RenalWest provides inpatient dialysis services, pursuant to contracts, to
16 acute-care hospitals in the Phoenix metropolitan area. Under these contracts,
a central office/warehouse operation dispatches equipment,
 
                                       55
<PAGE>   59
 
supplies and personnel required to perform dialysis treatments in connection
with the hospital's inpatient services. Such inpatient dialysis services are
required for patients with acute renal failure resulting from accidents, medical
and surgical complications, patients in the early stage of renal failure and
ESRD patients who require hospitalization for other reasons. The terms of these
contracts are individually negotiated and vary by contract. Currently,
RenalWest's hospital contracts specify predetermined fees per dialysis
treatment, although RenalWest believes that such fees may be subject to
negotiation in the future as provision of health care services becomes
increasingly influenced by managed care and subject to capitated arrangements.
 
  Staff Assisted Dialysis
 
   
     RenalWest provides staff-assisted dialysis services, pursuant to contracts,
with 37 skilled nursing facilities in the Phoenix metropolitan area. Such
dialysis services are required for patients who have been discharged to skilled
nursing facilities prior to being discharged to home and for other residential
alternative sites. Under these contracts, a central office/warehouse operation
dispatches equipment, supplies and personnel required to perform dialysis
treatments in connection with the skilled nursing facilities inpatient services.
The terms of these contracts are individually negotiated and vary by contract.
Currently, RenalWest staff assisted contracts specify predetermined fees per
dialysis treatment, although RenalWest believes that such fees may be subject to
negotiation in the future as provision of health care services becomes
increasingly influenced by managed care and subject to capitated arrangements.
    
 
  Relationships with Referral Sources, Medical Directors
 
     A key factor in the success of a dialysis center is its relationship with
local nephrologists. An ESRD patient generally seeks treatment at a center where
the patient's nephrologist has practice privileges. Consequently, RenalWest
relies on its ability to attract and to meet the needs of referring
nephrologists in order to receive and gain new referrals.
 
     RenalWest has engaged qualified physicians to serve as Medical Directors
for each of its centers. Generally, the Medical Director is a practicing,
board-eligible or board-certified nephrologist. Medical Directors'
responsibilities primarily consist of the administration and monitoring of
RenalWest's patient care policies, including patient education, administration
of dialysis treatment, development and training programs and assessment of all
patients. Coordination of the delivery of care is important in maintaining ESRD
patients' general level of health and in avoiding medical complications that
might necessitate hospitalization.
 
QUALITY ASSURANCE, IMPROVEMENT OF PATIENT CARE
 
  Improvements of Clinical Protocols Through Computerized Records
 
     RenalWest believes that the provision of high quality care to ESRD patients
reduces the aggregate costs associated with ESRD, and improves the patient's
quality of life by decreasing the number of days an ESRD patient spends in the
hospital. RenalWest believes that its implementation of a computerized, clinical
records system will provide it with timely access to information about causes
and lengths of hospitalization, resulting gross and standardized mortality
rates, as well as different types of treatment outcomes. This information is
used to assess care in individual centers and identify centers with excellent
outcomes so that standardized clinical protocols can be implemented, based on
those shown to result in positive outcomes and improved operating efficiencies.
 
  Quality Assurance
 
     In order to optimize therapy and improve outcomes, RenalWest monitors
patient outcomes in all of its centers. Regular monitoring of the prescribed
treatments and the key physiological parameters of patients constitutes part of
the continuous quality improvement that is conducted as a matter of RenalWest
policy.
 
     At the center level, pursuant to Medicare requirements, each center has a
quality assurance committee that typically includes the Medical Director,
Program Director, Clinical Manager, Dietitian, Social Worker
 
                                       56

and Operations Specialist. This committee meets regularly to monitor the quality
of care in the center and to assure compliance with applicable regulations.
 
   
     At the patient level, RenalWest attempts to ensure quality care through the
provision of instruction to all ESRD patients before and after the initiation of
dialytic therapy. Patients are encouraged to participate in their own care to
the fullest extent possible. In addition, in some of RenalWest's centers,
"self-care" units are formed in which self-reliance is fostered through
instruction and support.
    
 
  Outcomes Data
 
     RenalWest believes that an important factor in the successful management of
ESRD is access to a broad database of treatment-specific outcomes information
from which clinical pathways may be defined. RenalWest has begun the collection
of patient outcomes and cost data which it believes will assist it in
implementing clinical protocols to enhance patient outcomes while reducing the
cost of care. Management believes that the implementation of such protocols will
allow it to improve the overall quality and operating efficiencies of its
dialysis centers and to contract more effectively with payors in a health care
environment increasingly influenced by managed care.
 
  Medical Advisory Board
 
     The role of RenalWest's Medical Advisory Board is filled by the physician
members of the Board of Directors. A portion of the routine monthly Board
meeting is devoted to review of patient outcomes and assessment of clinical
protocols.
 
COMPETITION
 
   
     Although RenalWest presently has the largest market share in the
metropolitan Phoenix area and in the state of Arizona, it competes with many of
the nation's largest chain dialysis providers in its markets, several of which
have substantially greater financial and other resources than RenalWest. Its
principal competitors are National Medical Care, Total Renal Care, Vivra and
Ren/Gambro HealthCare.
    
 
PROPERTIES
 
   
     RenalWest operates 19 outpatient and three home dialysis centers, of which
20 are located in leased facilities and two of which are owned. RenalWest's
facilities are located exclusively in Arizona. RenalWest's leases generally have
terms ranging from five to seven years and contain renewal options. The sizes of
RenalWest's centers range from approximately 2,800 to 6,500 square feet, with an
average size of approximately 5,000 square feet. Additionally, RenalWest leases
three sites of approximately 1,100, 1,800 and 2,500 square feet to house its
biomedical repair department, facility maintenance department and acute dialysis
services warehouse. RenalWest leases office space in Mesa, Arizona for its
corporate headquarters under a lease that expires in 1999. RenalWest considers
its physical properties to be in good operating condition and suitable for the
purposes for which they are being used.
    
 
MEDICAID REIMBURSEMENT
 
     The Arizona Health Care Cost Containment System ("AHCCCS") is Arizona's
alternative to Medicaid. AHCCCS is funded through federal, state and county
governments. Unlike the traditional Medicaid model which pays a fee for service,
AHCCCS pays a monthly per capita amount to health plans who are responsible for
meeting the medical needs of those enrolled. The program also serves as a
supplement insurance program for the Medicare co-insurance portion and provides
certain coverages (e.g. oral medications) that are not covered by Medicare.
State regulations generally follow Medicare reimbursement levels and coverages
without any coinsurance amounts. RenalWest is a licenses ESRD AHCCCS provider in
Arizona.
 
                                       57
<PAGE>   61
 
PRIVATE REIMBURSEMENTS/ACUTE CARE CONTRACTS
 
     RenalWest receives reimbursement from private payors for ESRD treatments
prior to Medicare becoming a patient's primary payor at rates significantly
higher than the per treatment rate set by Medicare. After Medicare becomes a
patient's primary payor, private secondary payors generally reimburse RenalWest
for 20% of the Medicare per treatment rate. RenalWest has negotiated managed
care contracts with certain payors at rates that are equal to or higher than the
Medicare rate. RenalWest also receives payments from hospitals under 16 acute
care contracts at rates higher than the Medicare composite rate.
 
LEGAL PROCEEDINGS
 
     RenalWest is subject to claims and suits in the ordinary course of
business, including those arising from patient treatment which RenalWest
believes will be covered by malpractice insurance.

           UNAUDITED PROFORMA CONDENSED COMBINED FINANCIAL STATEMENTS
             OF RENAL CARE GROUP, INC., AND RENALWEST L.C., ET AL.
 
     The following unaudited pro forma condensed combined financial statements
are presented assuming the Merger will be accounted for as a pooling of
interests.
 
   
     The unaudited pro forma condensed combined balance sheet reflects the
combined historical balance sheets of Renal Care Group, Inc., at June 30, 1996
and RenalWest L.C. et al. ("RenalWest") at June 30, 1996. The unaudited pro
forma condensed combined income statements for the years ended December 31,
1993, 1994, 1995 and for the six months ended June 30, 1995 and 1996 reflect the
historical operating results of Renal Care Group, Inc. for such periods combined
with the historical operating results of RenalWest L.C. for such periods. The
historical operating results of Renal Care Group, Inc. give effect to the merger
with MainLine Suburban Dialysis Centers, Inc. The merger was effective April 26,
1996 and was accounted for as pooling-of-interests. As described more fully in
the notes accompanying the unaudited pro forma condensed combined financial
statements, the historical operations for the year ended December 31, 1993 of
RenalWest L.C. et al. represent operations from September 1, 1993 (date of
inception) through December 31, 1993.
    
 
     For all applicable periods presented in the pro forma condensed combined
income statements, shares used in the computation of earnings per share give
effect to the shares exchanged in the Merger.
 
     The pro forma financial statements are not necessarily indicative of the
results that would have been obtained had the Merger occurred on the dates
indicated. These pro forma financial statements should be read in conjunction
with the related historical financial statements and notes thereto of Renal Care
Group, Inc. and RenalWest.

                      RENAL CARE GROUP, INC. AND RENALWEST
 
      NOTES TO UNAUDITED PROFORMA CONDENSED COMBINED FINANCIAL STATEMENTS
                                 (IN THOUSANDS)
 
NOTE 1 -- BASIS OF PRESENTATION
 
     For accounting purposes, the Merger will be accounted for as a pooling of
interests. Accordingly, the accompanying unaudited pro forma combined financial
statements give retroactive effect to the Merger and include the combined
operations of RCG and RenalWest for all periods presented.
 
   
     In February 1996, RCG acquired simultaneously with the closing of the
Offering, five companies: Kidney Care, Inc. ("KCI"), and Medical Enterprises,
Ltd. ("MEL"), (KCI and MEL, collectively "Kidney Care"), D.M.N. Professional
Corporation ("DMN"), Tyler Nephrology Associates, P.A. ("TNA"), Kansas
Nephrology Association ("KNA"), and Renal Care Group, Inc., a Tennessee
Corporation ("RCG"). Effective April 26, 1996, the Company merged with MainLine
Suburban Dialysis Centers, Inc. The Company issued 528,000 shares in connection
with the Merger that was accounted for as a pooling-of-interests. The
accompanying statements of operations assume RCG had no operations prior to the
Offering in February 1996.
    
 
     Certain reclassifications have been made to the audited financial
statements to conform to the Renal Care Group, Inc. presentation.
 
NOTE 2 -- PRO FORMA ADJUSTMENTS
 
     The adjustment to the pro forma financial statements is as follows:
 
        (a)  To reflect the issuance of 2,400,000 shares in connection with the
             Merger resulting in an increase in common stock and corresponding
             reductions in additional paid-in capital.
 
NOTE 3 -- INCOME TAXES
 
     Estimated provision for income taxes related to pro forma adjustments are
provided assuming a combined federal and state income tax rate of 38%.
 
NOTE 4 -- EARNINGS PER SHARE
 
     Earnings per share for the period ended June 30, 1996 is based on the
weighted average number of shares outstanding during the period including the
dilutive effect of options and warrants. For all other periods presented,
weighted average shares outstanding represents the number of shares issued by
Renal Care Group, Inc. and the merger of RenalWest and Main Line Suburban
Dialysis Centers, Inc.
 
NOTE 5 -- MERGER EXPENSES
 
     No provision has been reflected in the unaudited pro forma condensed
combined financial statements for expenses expected to be incurred by RCG and
RenalWest in connection with the Merger. These expenses, consisting primarily of
investment advisory and professional fees, and expenses for printing and
distributing proxy materials, will be charged to expense upon completion of the
Merger.

1. ORGANIZATION AND BASIS OF PRESENTATION
 
     Renal Care Group, Inc. (of Delaware) (the "Company") was formed in June
1995, primarily for the purpose of acquiring four dialysis businesses and Renal
Care Group, Inc. (of Tennessee) ("Tennessee"), in exchange for shares of its
Common Stock, cash, notes payable and the assumption of certain debt (the
"Combination"). As discussed more fully in Note 6, on February 6, 1996, the
Company closed an initial public offering of 3,900 shares of its Common Stock
and simultaneously consummated the Combination. The four related businesses
acquired in the Combination, which are comprised of numerous legal entities,
conduct business as Kidney Care, Inc. and certain operating divisions of Medical
Enterprises, Ltd. and Health Care Suppliers, Inc. ("KCI"), Northeast Indiana
Kidney Center ("NEI"), Tyler Nephrology Associates, P.A. ("Tyler"), and Kansas
Nephrology Associates, P.A. ("KNA") and Kansas Dialysis Supply, Inc. ("KDS,"
combined, "Kansas"). Tennessee and the four unrelated businesses acquired are
based in Tennessee, Mississippi, Indiana, Texas, and Kansas.
 
     As mentioned above, on February 6, 1996, the Company completed an initial
public offering of 3,900 shares of Common Stock and on February 20, 1996, the
underwriters of the offering fully exercised their over allotment option for an

     On December 7, 1995, the Company issued an aggregate of principal amount of
$1,380 of Convertible Senior Subordinated Promissory Notes to provide funds to
complete the initial public offering. Such notes bear interest at a rate of 7%
per annum, mature on the first anniversary of their issuance, and the principal
and accrued interest thereof is convertible into shares of Common Stock of the
Company, beginning 180 days after the closing of the initial public offering, at
a conversion price of $7.50 per share. The Company offered such securities

3,900 shares of Common Stock and on February 20, 1996, the underwriters of the
offering fully exercised their over allotment option for an additional 585

exchanged 4,831 shares of Common Stock, plus cash, notes payable and the
assumption of certain debt for either stock or selected assets and liabilities

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1994
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
  Organization and Basis of Presentation
 
     Main Line Suburban Dialysis Centers, Inc. ("the Company") is a group of
five dialysis centers located in the greater Philadelphia area. Prior to 1994,
these five dialysis centers functioned as individual entities all owned by the
same parties. These companies consisted of Bryn Mawr Dialysis Services, P.C. and
Valley Forge Dialysis Center, P.C. both organized as subchapter-S corporations
and Main Line Dialysis Services, Ltd., Haverford Dialysis Unit, Ltd., and
Dialysis Center of Montgomery, Ltd. which were organized as professional
corporations. Effective January 1, 1994, four of these individual centers were
combined into the remaining center, Haverford Dialysis Unit, Ltd. which was
renamed Main Line Suburban Dialysis Centers, Inc. and converted to subchapter-S
status. The shareholders and partners of the previous five entities dissolved
their respective interests in these individual entities in exchange for shares
of common stock of the Company. The assets and liabilities of the Company,
effective January 1, 1994 are the same as the combined assets and liabilities of
the individual entities.
 
  Net Patient Service Revenue
 
     Net patient service revenue is reported on the accrual basis in the period
in which services are provided at established rates, net of contractual
adjustments and other discounts. The majority of patient services are rendered
through Medicare under which reimbursement is based on specific rates for
services rendered.
 
  Leasehold Improvements and Equipment
 
     Leasehold improvements and equipment are recorded at cost. When an asset is
sold, retired or otherwise disposed of, the cost of the asset and related
accumulated depreciation is removed from the respective accounts, and any
resulting gains or losses are reflected as other revenue.
 
     Depreciation is provided over the estimated useful lives of fixed assets on
the straight-line method.
 
  Supplies
 
     Supplies are carried at the lower of cost or market based on the first-in,
first-out method.
 
2. PENSION PLAN
 
     The Company has a 401(k) plan covering substantially all employees.
Annually, the Company contributes to the plan three percent of the gross
compensation of each eligible participant. Participants in the plan may also
elect to contribute between five and fifteen percent of their gross annual
compensation. For those participants who elect to contribute, the Company will
fund up to an additional three percent of these participants' gross annual
compensation. During 1994, the Company contributed $246,000 to the 401(k) plan.
 
3. RELATED PARTY TRANSACTIONS
 
     Physician services are provided to the Company by Nephrology Associates,
Inc. a physician group whose shareholders are also shareholders of Main Line
Suburban Dialysis Centers, Inc. This group provides management, training,
billing, and medical services for the Company under a management agreement which
is renewable annually. Nephrology Associates, Inc. maintains professional
malpractice liability insurance for each of its physicians. During 1994 the
Company paid Nephrology Associates, Inc. $2,332,000 for physician services and
executive management fees pursuant to a management agreement with Nephrology
Associates, Inc. The Company also paid Nephrology Associates, Inc. $221,250 for
administrative services during 1994.

Inc. to continue as a going concern. Substantially all of the dialysis
treatments performed by the Company are referred by the physicians of Nephrology
Associates, Inc.
 
     The shareholders of the Company have also established an organization named
Main Line Medical Leasing from which the Company has borrowed amounts to
purchase equipment. At December 31, 1994 the Company had $211,681 due to Main
Line Medical Leasing which was included in long-term debt.
 
     During 1994 the Company loaned Nephrology Associates, Inc. $75,000. There

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
1. SIGNIFICANT ACCOUNTING POLICIES:
 
  Organization and Basis of Presentation:
 
     Main Line Suburban Dialysis Centers, Inc., ("the Company") is a group of
five dialysis centers located in the greater Philadelphia area. Prior to 1994,
these five dialysis centers functioned as individual entities all owned by the
same parties. These companies consisted of Bryn Mawr Dialysis Services, P.C. and
Valley Forge Dialysis Center, P.C. both organized as subchapter-S corporations
and Main Line Dialysis Services, Ltd., Haverford Dialysis Unit, Ltd., and
Dialysis Center of Montgomery, Ltd. which were organized as professional
corporations. Effective January 1, 1994, four of these individual centers were
combined into the remaining center, Haverford Dialysis Unit, Ltd. which was
renamed Main Line Suburban Dialysis Centers, Inc. and converted to subchapter-S
status. The shareholders and partners of the previous five entities dissolved
their respective interests in these individual entities in exchange for shares
of common stock of the Company. The assets and liabilities of the Company,
effective January 1, 1994 are the same as the combined assets and liabilities of
the individual entities.
 
  Net Patient Service Revenue:
 
     Net patient service revenue is reported on the accrual basis in the period
in which services are provided at established rates, net of contractual
adjustments and other discounts. The majority of patient services are rendered
through Medicare under which reimbursement is based on specific rates for
services rendered.
 
  Leasehold Improvements and Equipment:
 
     Leasehold improvements and equipment are recorded at cost. When an asset is
sold, retired or otherwise disposed of, the cost of the asset and related
accumulated depreciation is removed from the respective accounts, and any
resulting gains or losses are reflected as other revenue.
 
     Depreciation is provided over the estimated useful lives of fixed assets on
the straight-line method.
 
  Supplies:
 
     Supplies are carried at the lower of cost or market based on the first-in,
first-out method.
 
  Use of Estimates:
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
2. PENSION PLAN:
 
     The Company has a 401(k) plan covering substantially all employees.
Annually, the Company contributes to the plan three percent of the gross
compensation of each eligible participant. Participants in the plan may also
elect to contribute between five and fifteen percent of their gross annual
compensation. For those participants who elect to contribute, the Company will
fund up to an additional three percent of these participants' gross annual
compensation. The Company's contribution totals $103,241 for 1995.

Inc. a physician group whose shareholders are also shareholders in Main Line
Suburban Dialysis Centers, Inc. This group provides management, training,
billing, and medical services for the Company under a management agreement which
is renewable annually. Nephrology Associates, Inc. maintains professional
malpractice liability insurance for each of its physicians. During 1995 the
Company incurred $786,594 for physician services and executive management fees
pursuant to a management agreement with Nephrology Associates, Inc. The Company
also incurred $242,844 for administrative services during 1995.
 
     The Company is dependent upon the relationship with Nephrology Associates,
Inc. to continue as a going concern. Substantially all of the dialysis
treatments performed by the Company are referred by the physicians of Nephrology
Associates, Inc.
 
     The shareholders of the Company have also established an organization named
Main Line Medical Leasing from which the Company has borrowed amounts to
purchase equipment. At December 31, 1995 the Company had $177,358 due to Main
Line Medical Leasing which was included in long term debt.
 
     During 1995, Nephrology Associates, Inc. loaned the Company $20,000. There
are no terms or interest rates associated with this loan.
 
4. INSURANCE PROGRAMS:
 
     The Company purchases individual occurrence basis professional liability
insurance for all of the nurses and dialysis technicians with a commercial
carrier. The Company also maintains general liability insurance through a claims
made insurance policy. As of December 31, 1995, management is unaware of any

</TABLE>
 
     The Company has an unsecured line of credit available for $20,000 from a
local bank. At December 31, 1995 no amounts were outstanding relative to this
line of credit.
 
6. INCOME TAXES:
 
     The shareholders of the Company have elected subchapter S status of the
Internal Revenue Code. Accordingly, there has been no provision made for Federal
and state income taxes as the liability for such taxes, if any, is attributed to
the individual shareholders.
 
7. LEASES:
 
     The Company rents office space from Lankenau Hospital on a year to year
basis, for which the current monthly rental is $11,575. The Company rents space
at Bryn Mawr Hospital on a monthly basis, for which the current monthly rental
is $6,673. During 1995, the company entered into a seven-year lease with
Montgomery Hospital for the rent of medical office space for the period November
1, 1995 to October 31, 2002, for which the currently scheduled monthly payment
is $4,386.
 
     The Company occupies space in the Phoenixville Medical Building located at
Phoenixville Hospital, and is currently paying rent pursuant to a lease
agreement an affiliate has with the landlord of Phoenixville Medical Building.
It is management's intention that the payment of rent on behalf of the affiliate
is being made pursuant to a sublease agreement between the Company and the
affiliate. It is also management's intention that the terms of the sublease
include provisions that would obligate the Company to make required rent
payments over a period of years to the affiliate, in the same way and under the
same terms as the affiliate is obligated to the landlord of Phoenixville Medical
Building. However, such a sublease would not eliminate the obligations the
affiliate has under the terms of its lease with the landlord of Phoenixville
Medical Building. The sublease agreement between the Company and its affiliate
is currently an oral agreement. The current monthly rent is $4,292.
 
     Total payments made under these leases totaled $325,747 in 1995. Future
minimum rental payments under these leases are as follows:

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The monthly rent payment for the Phoenixville Medical Building generally
increases each year, and is scheduled to increase to $4,588 effective February
1, 1996. The schedule of minimum rental payments above reflects the intentions
of management regarding the oral sublease agreement, and does not reflect future
annual increases above the $4,588 monthly rent.
 
     The Company also reimburses Nephrology Associates, Inc., an affiliated
corporation, for office space shared at Lankenau Hospital. The Company paid
Nephrology Associates, Inc. $21,899 in 1995.
 
8. CONCENTRATIONS OF CREDIT RISK:
 
     The Company maintains its cash in bank deposit accounts which, at times,
may exceed federally insured limits. At December 31, 1995, the Company's
uninsured cash balances totaled $549,021.
 
9. SIGNIFICANT ESTIMATES:
 
  Accounts Receivable:
 
     Patient accounts receivable totals $2,872,484 at December 31, 1995, of
which $830,981 has aged 120 or more days. Management estimates that at most
approximately 98% of these accounts will be uncollectible. The allowance for
doubtful accounts of $814,231 as of December 31, 1995 represents approximately
98% of the accounts aged 120 or more days.
 
     The Company's policy is to record patient service revenue net of
contractual adjustments and other discounts. Management estimates that the
contractual adjustments recorded for accounts aged less than 120 days has in
effect stated these accounts at their net realizable value; and therefore,
management believes that an additional allowance for doubtful accounts is not
warranted.
 
     It is at least reasonably possible that a change in the estimate of the
probability of collecting patient accounts receivable existing as of December
31, 1995 will occur in the near term. However, in the opinion of management,
this estimate at December 31, 1995 is reasonable.
 
  Accrued Vacation and Sick Pay:
 
     The Company has adopted a policy whereby all full-time and "part-time with
benefits" employees with one or more years of service are eligible for paid
absences. These absences are categorized as either "basic leave" or "extended
illness leave".
 
     Basic leave includes scheduled vacation days and short-term illnesses.
Extended illness leave includes absences caused by illness that for full-time
employees begins on the fourth consecutive work day of illness, and for eligible
part-time employees begins on the sixth consecutive calendar day of any illness.
Basic leave, within certain limits, may be carried over from one year to the
next. In addition, employees may, within certain limits, opt to receive wages
for basic leave days earned, and may be paid for unused basic leave days upon
termination of employment. Unused extended illness leave is not paid upon
termination.
 
     The estimated maximum vacation and sick pay related to the basic leave is
$128,355 as of December 31, 1995. Since employees may from time to time opt to
receive wages for basic leave days earned, and employees may carry over unused
basic leave days earned, management has accrued 100% of the value of the basic
leave days earned.
 
     The estimated maximum sick pay related to the extended illness leave is
$393,684 as of December 31, 1995. Management has assessed the probability of
incurring the maximum cost at 10%. Accordingly, management has accrued $39,368,
or 10% of the value of the estimated maximum extended illness leave.

     It is at least reasonably possible that a change in the estimate of the
maximum vacation and sick pay, or the probability of incurring the maximum cost,
will occur in the near term. However, in the opinion of management, these
estimates at December 31, 1995 are reasonable.
 
  Restatement of Shareholders' Equity:
 
     As of December 31, 1994, the Company had stock subscriptions outstanding
totaling $38,254; and effective December 31, 1994, the Company had purchased
4 1/2 shares of stock from its shareholders at a total cost of $6,478. Neither
transaction was reflected in the financial statements for the year ended
December 31, 1994. As a result, total shareholders' equity was understated by
$31,776. Accordingly, the statement of changes in shareholders' equity for the
year ended December 31, 1995 includes an adjustment to restate the balance of
shareholders' equity as of December 31, 1994.

1. SIGNIFICANT ACCOUNTING POLICIES:
 
  Organization and Basis of Presentation:
 
     Main Line Suburban Dialysis Centers, Inc., ("the Company") is a group of
five dialysis centers located in the greater Philadelphia area. Prior to 1994,
these five dialysis centers functioned as individual entities all owned by the
same parties. These companies consisted of Bryn Mawr Dialysis Services, P.C. and
Valley Forge Dialysis Center, P.C. both organized as subchapter-S corporations
and Main Line Dialysis Services, Ltd., Haverford Dialysis Unit, Ltd., and
Dialysis Center of Montgomery, Ltd. which were organized as professional
corporations. Effective January 1, 1994, four of these individual centers were
combined into the remaining center, Haverford Dialysis Unit, Ltd. which was
renamed Main Line Suburban Dialysis Centers, Inc. and converted to subchapter-S
status. The shareholders and partners of the previous five entities dissolved
their respective interests in these individual entities in exchange for shares
of common stock of the Company. The assets and liabilities of the Company,
effective January 1, 1994 are the same as the combined assets and liabilities of
the individual entities.
 
2. UNAUDITED INTERIM FINANCIAL INFORMATION
 
     The balance sheet as of June 30, 1995 and related statements of operations
and cash flows for the period ended June 30, 1995 have been prepared by
management and are unaudited. The interim financial statements include all
adjustments, consisting of only normal recurring adjustments necessary for a
fair presentation of the interim results.
 
     Certain information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted from the interim financial statements. The

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors
RENALWEST L.C.
 
     We have audited the accompanying combined balance sheets of RENALWEST L.C.,
et al. (see Note 1) as of December 31, 1995 and 1994, and the related combined
income statements, statements of changes in owners' equity, and cash flows for
the years then ended. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the combined financial position of RENALWEST L.C., et
al. at December 31, 1995 and 1994, and the combined results of their operations
and their cash flows for the years then ended, in conformity with generally
accepted accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
1. ORGANIZATION AND BASIS OF PRESENTATION
 
     RENALWEST L.C., et al. (the "Company") consists of RENALWEST L.C.
("RENALWEST") its owner members, including 9-CO., Inc., and 3-CO., Inc., and its
wholly owned subsidiary RENALWEST Health Supply L.C. 9-CO., Inc. and 3-CO., Inc.
are both organized as S Corporations.
 
     RENALWEST, a limited liability company, was formed on September 1, 1993
from the combination of assets and liabilities of 13 commonly-owned S
corporations. RENALWEST provides dialysis services for patients with End Stage
Renal Disease (ESRD) in an outpatient setting, in a patient's residence or in a
hospital. At December 31, 1995, RENALWEST operated 17 outpatient hemodialysis
facilities, three peritoneal dialysis training centers, and a staff-assisted
hemodialysis program, and had contracts for inpatient dialysis at 17 hospitals.
 
     The owner members of RENALWEST are not liable for any debts, liabilities or
other obligations of RENALWEST except as agreed upon by all owner members. As
currently structured, RENALWEST must dissolve by December 31, 2050.
 
     Approximately 60 and 70 percent of the Company's accounts receivable at
December 31, 1994 and 1995, respectively, are from Medicare and the Arizona
Healthcare Cost Containment System (AHCCCS). Accordingly, revenues and cash
flows are dependent upon the rates set by, and the promptness of payment from,
Federal and State administered programs, and in management's opinion do not
create a significant credit risk to the Company.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Combination
 
     The combined financial statements include the accounts of the Company.
Significant intercompany transactions and accounts have been eliminated in
combination.
 
  Cash Equivalents
 
     The Company considers all highly-liquid investments with original
maturities of three months or less to be cash equivalents.
 
  Inventory
 
     Inventory consists of drugs, supplies and parts consumed in dialysis
treatments and is stated at the lower of cost (using the average method) or
market.
 
  Property and Equipment
 
     Property and equipment are stated at cost. Depreciation is provided by the
straight-line method over the useful lives of the related assets, generally

11. INSURANCE
 
     Health care companies are subject to medical malpractice, personal injury
and other liability claims that are customary risks inherent in the operation of
health facilities and are generally covered by insurance. The Company maintains
property, liability and professional malpractice insurance policies through
commercial carriers on a claims made basis in amounts and with such coverages
and deductibles that are deemed appropriate by management, based upon historical
claims, industry standards and the nature and risks of its business. There can
be no assurance that a future claim will not exceed available insurance
coverages or that such coverages will continue to be available for the same
scope of coverages at reasonable premium rates. Any substantial increase in the
cost of such insurance or the unavailability of any such coverages could have an
adverse effect on the Company's business.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                                 JUNE 30, 1996
 
1. ORGANIZATION AND BASIS OF PRESENTATION
 
     RENALWEST L.C., et al. (the "Company") consists of RENALWEST L.C.
("RENALWEST") its owner members, including 9-CO., Inc., and 3-CO., Inc., and its
wholly owned subsidiary RENALWEST Health Supply L.C. 9-CO., Inc. and 3-CO., Inc.
are both organized as S Corporations.
 
     RENALWEST, a limited liability company, was formed on September 1, 1993
from the combination of assets and liabilities of 13 commonly-owned S
corporations. RENALWEST provides dialysis services for patients with End Stage
Renal Disease (ESRD) in an outpatient setting, in a patient's residence, or in a
hospital. At December 31, 1995, RENALWEST operated 17 outpatient hemodialysis
facilities, three peritoneal dialysis training centers, and a staff-assisted
hemodialysis program, and had contracts for inpatient dialysis at 17 hospitals.
 
     The owner members of RENALWEST are not liable for any debts, liabilities or
other obligations of RENALWEST except as agreed upon by all owner members. As
currently structured, RENALWEST must dissolve by December 31, 2050.

nephrology services founded in June 1995. The Company provides dialysis and
ancillary services to approximately 3,600 patients through 52 outpatient
dialysis centers in twelve states. In consideration for this transaction, the

3. UNAUDITED INTERIM FINANCIAL INFORMATION
 
     The balance sheet as of June 30, 1996 and the statements of operations and
cash flows for the six months ended June 30, 1996 and 1995 (interim financial
statements) have been prepared by management and are unaudited. The interim
financial statements include all adjustments, consisting of only normal
recurring adjustments necessary for a fair presentation of the interim results.
 
     Certain information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted from the interim financial statements. The
interim financial statements should be read in conjunction with the December 31,
1994 and 1995 audited combined financial statements appearing herein. The
results of the six months ended June 30, 1995 and 1996 may not be indicative of
operating results for the full respective years.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors and Stockholders
Renal Care Group, Inc.
 
     We have audited the accompanying combined balance sheets of Renal Care
Group, Inc. (of Tennessee) and Three Unrelated Businesses to be Acquired, as
identified in Note 1, as of December 31, 1993 and 1994 and June 30, 1995, and
the related combined statements of operations, owners' equity and cash flows for
each of the three years in the period ended December 31, 1994 and the six months
ended June 30, 1995. These financial statements are the responsibility of the
companies' management. Our responsibility is to express an opinion on these
financial statements based on our audits. We did not audit the financial
statements of Tyler Nephrology Associates, P.A. and the combined financial
statements of Kansas Nephrology Associates, P.A. and Kansas Dialysis Supply,
Inc., which statements reflect total assets constituting 63% in 1993, 57% in
1994, and 53% in 1995 and total revenues constituting 71% in 1992, 68% in 1993,
68% in 1994, and 66% for the six months ended June 30, 1995 of the related
combined totals. Those statements were audited by other auditors whose reports
have been furnished to us, and our opinion, insofar as it relates to data
included for Tyler Nephrology Associates, P.A. and the combined financial
statements of Kansas Nephrology Associates, P.A. and Kansas Dialysis Supply,
Inc., is based solely on the reports of the other auditors.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits and the reports of other auditors provide a
reasonable basis for our opinion.
 
     In our opinion, based on our audits and the reports of other auditors, the
financial statements referred to above present fairly, in all material respects,
the combined financial position of Renal Care Group, Inc. (of Tennessee) and
Three Unrelated Businesses to be Acquired at December 31, 1993 and 1994 and June
30, 1995, and the combined results of their operations and their cash flows for
each of the three years in the period ended December 31, 1994 and six months
ended June 30, 1995, in conformity with generally accepted accounting
principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
                                 JUNE 30, 1995
 
1. ORGANIZATION AND BASIS OF PRESENTATION
 
   
     Renal Care Group, Inc. (of Delaware) ("the Company") was formed in June
1995, primarily for the purpose of acquiring four dialysis businesses and Renal
Care Group, Inc. (of Tennessee) ("Tennessee"), in exchange for shares of its
Common Stock, cash, notes payable and the assumption of certain debt (the
"Combination"). The Combination is to be effected in accordance with executed
combination agreements with the four dialysis businesses and Tennessee and is
subject to the closing of the initial public offering of the Company (the
"Offering"). Kidney Care, Inc. and certain operating divisions of Medical
Enterprises, Ltd. and Health care Suppliers, Inc. (collectively "Kidney Care")
has been designated as the Predecessor and thus Kidney Care's financial
statements are not included in these combined financial statements. The Three
Unrelated Businesses to be Acquired, which comprise numerous legal entities,
conduct business as Northeast Indiana Kidney Center ("NEI"), Tyler Nephrology
Associates, P.A. ("Tyler"), and Kansas Nephrology Associates, P.A. ("KNA") and
Kansas Dialysis Supply, Inc. ("KDS," and with KNA, "Kansas"). Tennessee and
Three Unrelated Businesses to be Acquired are based in Tennessee, Indiana,
Texas, and Kansas. Effective July 31, 1995, D.M.N. Professional Corporation,
which is owned by the physician owners of NEI, bought the remaining 50%
ownership interest in NEI from its former joint venture partner (See Note 13).
The joint venture which is NEI is included in these combined financial
statements.
    
 
     Physician services are provided to the Three Unrelated Businesses to be
Acquired by physician groups, which comprise shareholders, partners or legal
entities owned by shareholders or partners of the Three Unrelated Businesses to
be Acquired. Substantially all of the dialysis treatments performed by the Three
Unrelated Businesses to be Acquired are referred by these related physician
groups.
 
     Tennessee and the Three Unrelated Businesses to be Acquired previously have
operated as separate independent entities. Their historical financial positions,
results of operations and cash flows have been combined in the accompanying
financial statements and do not reflect any adjustments relating to the
Combination or the impacts that may have occurred if the operations of Tennessee
and the Three Unrelated Businesses to be Acquired had been combined. All
significant intercompany accounts and transactions have been eliminated.
 
     Two of the Three Unrelated Businesses to be Acquired maintain their books
and records on the cash basis of accounting. The accompanying financial
statements have been prepared on the accrual basis of accounting. These combined
financial statements have been prepared to show the combined operations and
combined financial position of Tennessee and Three Unrelated Businesses to be
Acquired. Certain entities are not required to pay federal or state income taxes
(due to their status as partnerships, S Corporations and corporations managed to
result in taxes being the responsibility of the respective owners), as further
described in Note 2.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
NET REVENUE
 
     Accounts receivable and net revenue are recorded at the estimated net
realizable amount from Medicare, Medicaid, patients, commercial insurers, and
other third-party payors for services rendered. The Medicare and Medicaid
programs reimburse Tennessee and Three Unrelated Businesses to be Acquired at
amounts that are different from the Company's established rates. Contractual
adjustments under these programs represent the difference between the amounts
billed for these services and the amounts that are reimbursable by third-party
payors. A summary of the basis for reimbursement with these payors follows:
 
                                      F-64

                   THREE UNRELATED BUSINESSES TO BE ACQUIRED
 
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Medicare
 
     Tennessee and Three Unrelated Businesses to be Acquired are paid by the
Medicare program on a prospective payment system for dialysis services. Each
facility receives a composite rate that is adjusted to account for geographic
differences in the cost of labor. The prospectively determined composite rates
are not subject to retroactive adjustments.
 
  Medicaid
 
     Medicaid is a state administered program with reimbursements varying by
state. The Medicaid programs administered by each of Indiana, Ohio, Texas,
Kansas and Tennessee, reimburse Tennessee and the respective Three Unrelated
Businesses to be Acquired.
 
     Other payments from patients, commercial insurers, and other third-party
payors are received pursuant to a variety of reimbursement arrangements, which
are generally higher than those payments received from the Medicare and Medicaid
programs.
 
     The allowance for doubtful accounts represents management's estimate of
potential credit losses associated with amounts due from patients, commercial
insurers, and other third-party payors. Management of Tennessee and Three
Unrelated Businesses to be Acquired does not believe that receivables from the
Medicare and Medicaid programs represent any significant credit risk.
 
     Reimbursements from Medicare and Medicaid at established rates approximated
68%, 68%, and 64% of patient service revenue for the years ended December 31,
1992, 1993 and 1994, respectively, and 67% for the six months ended June 30,
1995.
 
CASH AND CASH EQUIVALENTS
 
     For the purpose of the combined statements of cash flows, cash and cash
equivalents include demand deposits and money market accounts at a financial
institution. All highly liquid investments with a maturity of three months or
less when purchased are considered to be cash equivalents. The carrying amount
reflected on the balance sheet at December 31, 1993 and 1994 and June 30, 1995
is equal to approximate fair value.
 
HELD-TO-MATURITY SECURITIES
 
     Management determines the appropriate classification of debt securities at
the time of purchase and reevaluates such designation as of each balance sheet
date. Debt securities are classified as held-to-maturity when there is the
positive intent and ability to hold the securities to maturity. Held-to-maturity
securities are stated at cost, adjusted for amortization of premium and
accretion of discount to maturity. Any such amortization is included in interest
income. Any interest received on securities classified as held-to-maturity is
included in interest income. All held-to-maturity securities mature within one
year of the balance sheet date.
 
INVENTORIES
 
     Inventories consist of dialysis supplies and are stated at the lower of
cost under the first-in, first-out method or market.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment are stated at cost and depreciated using the
straight-line method over the estimated useful lives of the assets. The general
range of useful lives is five to 40 years for buildings and leasehold
improvements (limited to the terms of the lease including expected renewal
periods), and five to 15 years for furniture, fixtures and equipment. Routine
maintenance and repairs are expensed as incurred, while costs of betterments and
renewals are capitalized.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
OTHER ASSETS
 
     Included in other assets are escrow deposits related to a performance
guarantee agreement between Kansas and a local hospital, which originated in
1986. Such agreement requires Kansas to deposit $8 per month with a designated
money manager until 1996, at which time Kansas will have unrestricted use of the
amounts deposited and any earnings thereon if it has fulfilled certain
obligations thereto. In the opinion of management of Kansas, the assets relating
to this guarantee are deemed fully collectible.
 
INCOME TAXES
 
     The Three Unrelated Businesses to be Acquired are S Corporations or
partnerships; accordingly, income tax liabilities are the responsibility of the
respective owners or partners. Under these provisions, the Three Unrelated
Businesses to be Acquired generally do not pay corporate income taxes; rather
the income or loss is allocated to each stockholder for inclusion in their
respective income tax returns. Because of this practice, provisions for income
taxes and deferred tax assets and liabilities of these taxable entities have not
been reflected in these combined financial statements.
 
     Tennessee is a C Corporation and accounts for income taxes under the
liability method. Under this method, deferred tax assets and liabilities are
determined based upon differences between financial reporting and tax basis of
assets and liabilities and are measured using the enacted tax and laws that will
be in effect when the differences are expected to reverse.
 
ESTIMATED MEDICAL PROFESSIONAL LIABILITY CLAIMS
 
     Tennessee and each of the Three Unrelated Businesses to be Acquired are
insured for medical professional liability claims through retrospectively rated
commercial insurance policies. It is their respective policies that provision
for estimated premium adjustments to medical professional liability costs be
made for asserted and unasserted claims and based upon their experiences.
Provision for such professional liability claims includes estimates of the
ultimate costs of such claims. To date, their experiences with such claims has
not been significant. Accordingly, no such provision has been made.
 
OWNERS' EQUITY
 
     Owners' equity includes the respective capital stock, additional paid-in
capital, partnership capital, and retained earnings of the various legal
entities reflected herein. The Three Unrelated Businesses to be Acquired have
multiple owners, various types of agreements exist among the owners which call
for the transfer of a physician's ownership interest by the continuing owners in
the case of certain events such as the owner's retirement or death. Frequently,
the existing owners are required to pay the departed owner for his interest.
 
3. CASH, CASH EQUIVALENTS AND HELD-TO-MATURITY SECURITIES
 
     In May 1993, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 115, "Accounting for Certain Investments in
Debt and Equity Securities." Tennessee adopted the provisions of the new
standard for investments held as of or acquired after January 1, 1994. In
accordance with the Statement, prior period financial statements have not been
restated to reflect the change in

facility with a bank leasing interest at the bank's reference rate (8.5% at
December 31, 1994 and 9.35% at June 30, 1995), in the amount of $500. There were
no borrowings at December 31, 1994 and June 30, 1995.
 
     Certain debt obligations contain covenants that require maintenance of
certain financial ratios. Default of any covenant could affect the ability of
individual entities to borrow under the agreements and, if not waived or
corrected, could accelerate the maturity of any borrowings outstanding under the
agreements. As of June 30, 1995, Tennessee and each of the Three Unrelated
Businesses to be Acquired had complied with existing loan covenants. Various of
these debt instruments are guaranteed by the respective owners or related

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
PRO FORMA INCOME TAX INFORMATION (UNAUDITED)
 
     As discussed in Note 2, the Three Unrelated Businesses to be Acquired
operate under Subchapter S of the Internal Revenue Code and are not subject to
corporate federal income tax. In connection with the contemplated initial public
offering (see Note 13), the Subchapter S election will be terminated. As a
result, the Three Unrelated Businesses to be Acquired will be subject to
corporate income taxes subsequent to the termination of S Corporation status.
Tennessee and Three Unrelated Businesses to be Acquired had net operating income
for income tax purposes of $5,366, $5,963, and $6,341 and $2,160 for 1992, 1993,
1994, and the six months ended June 30, 1995, respectively. Had Tennessee and
Three Unrelated Businesses to be Acquired filed federal and state income tax
returns as a regular corporation for 1992, 1993, 1994, and the six months ended
June 30, 1995, income tax expense under the provisions of Financial Accounting
Standard No. 109 would have been $2,162, $2,457, $2,455, and $949, respectively.
 
     At the date of termination of S Corporation status, Tennessee and Three
Unrelated Businesses to be Acquired will be required to provide for a deferred
tax liability for cumulative temporary differences between financial reporting
and tax reporting. Such deferred taxes will be based on the cumulative temporary
difference at the date of termination of S Corporation status. The effect of
recognizing the deferred taxes will be included in income from continuing
operations. If the termination of S Corporation status had occurred at June 30,
1995, the deferred income tax liability would have been approximately $181.

statements based on our audits.
    
 
     We conducted our audits in accordance with generally accepted auditing

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

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

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

     Kidney Care, Inc., et al. ("Kidney Care") consists of Kidney Care, Inc.
("KC") and certain operating divisions of its affiliates, Medical Enterprises,
Ltd. ("MEL") and Health Care Suppliers, Inc. ("HSI"). Kidney Care operates

calendar days) after the Effective Time, RCG and the Company shall cause the
exchange agent selected by RCG (the "Exchange Agent") to mail to the former
holders of Member Common Stock appropriate transmittal materials (which shall
specify that delivery shall be effected, and risk of loss and title to the
certificates theretofore representing shares of Member Common Stock shall pass,
only upon proper delivery of such certificates to the Exchange Agent).  After

shares to be canceled pursuant to Section 3.3 of this Agreement) issued and
outstanding at the Effective Time shall surrender the certificate or
certificates representing such shares to the Exchange Agent and shall promptly
upon surrender thereof receive in exchange therefor the consideration provided
in Section 3.1 of this Agreement.  RCG shall not be obligated to deliver the
consideration to which any former holder of Member Common Stock is entitled as
a result of the Merger until such holder surrenders his certificate or
certificates representing the shares of Member Common Stock for exchange as

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

Company and the Owners, there are no encroachments, leases, easements,
covenants, restrictions, reservations or other burdens of any nature which
might impair in any material respect the use of any leased real property in a
manner consistent with past practices nor does any part of any building
structure or any other improvement thereon encroach on any other property.

     (c) The present zoning, subdivision, building and other ordinances and
regulations applicable to the leased real property permit the continued
operation, use, occupancy and enjoyment of such real property consistent with
past practices, and each Company is in compliance with, and has received no
notices of violations of, any applicable zoning, subdivision or building
regulation, ordinance or other law, regulation, or requirement.  Each Company
has all rights and easements necessary for public ingress thereto and egress
therefrom and for the provision of all utility services thereto, including any
required curb cut or street opening permits or licenses for vehicular access
over presently existing roads and driveways.

     (d) Each Company's assets (including all buildings and improvements in
connection therewith) are in good operating condition and repair, ordinary wear
and tear excepted (and except where the failure to be in such condition and
repair, either individually or in the aggregate, would not have a material
adverse effect on the Companies taken as a whole, financial or otherwise), and
such assets include all rights, properties, interests in properties, and assets
necessary to permit  the Companies to continue their business after the Closing
Date as presently conducted, with the Members becoming wholly owned
subsidiaries of RCG.

technology rights and licenses, know-how, software and patents, registrations
thereof and applications therefor, and any other intellectual property used in
the business of each Company, together with a complete list of all licenses
granted by or to each Company with respect to any of the foregoing.  Neither
the Company nor any of the Owners is currently in receipt of any notice of any
violation of, and each has no reason to believe that the Company's operations
are violating, the rights of others with respect to any such matter, and the
Company has taken reasonable measures to protect its rights with respect to any
such matters as are proprietary to the Company.

     5.13 Contracts and Commitments.  (a)  Schedule 5.13 contains a complete
and accurate list of all contracts, agreements, commitments, instruments and

     (b) Each Company has delivered to RCG true and complete copies of all of
its Company Agreements.  Except as indicated on Schedule 5.13, the Company
Agreements are valid and effective in accordance with their terms, and there is
not under any of such Company Agreements (i) any existing or claimed default by
any Company or event which with the notice or lapse of time, or both, would
constitute a material default by such Company or (ii) to the knowledge of the
Companies and the Owners, any existing or claimed default by any other party or
event which with notice or lapse of time, or both, would constitute a material
default by any such party.  Except as indicated on Schedule 5.13, the
continuation, validity and effectiveness of the Company Agreements will not be
affected by the Mergers and the Mergers will not result in a breach of or
default under, or require the consent of any other party to, any of the Company
Agreements.  There is no actual or, to the knowledge of the Companies and the
Owners, threatened termination, cancellation or limitation of any Company
Agreements that would have a material adverse effect on the Companies taken as
a whole, financial or otherwise.  To the knowledge of the Companies and the
Owners, there is no pending or threatened bankruptcy, insolvency or similar
proceeding with respect to any other party to the Company Agreements.

applicable laws respecting employment and employment practices, terms and

as a whole, financial or otherwise, and, to the knowledge of the Companies and
the Owners, no basis for any such matter exists;

     (ii) to the knowledge of the Companies and the Owners, there are no
inquiries, investigations or monitoring of activities of any licensed,

     5.16 Insurance Policies.  Except as described on Schedule 5.16, all of the
assets and business of each Company are insured in such amounts and against
such losses, casualties or risks as are customary for similar properties and
businesses, and the Company has maintained such insurance continuously from the
earlier of (i) the date of its inception and (ii) the date of inception of any
of its predecessors.  Schedule 5.16 sets forth a complete and accurate list and
description of all insurance policies in force naming each Company, or any
employee thereof, as an insured or beneficiary or as a loss payee or for which
the Company has paid or is obligated to pay all or part of the premiums,
including, without limitation, all liability, malpractice, fire, health and
life insurance policies.  All such policies are in full force and effect and

otherwise) with respect thereto, and, to the knowledge of the Companies and the
Owners, each Company is in compliance with all conditions contained therein.
Except as set forth on Schedule 5.16, there are no pending claims against such
insurance by any Company as to which insurers are defending under reservation
of rights or have denied liability, and except as set forth on Schedule 5.16,
there exists no claim under such insurance that has not been properly filed by
any Company.  To the knowledge of the Companies and the Owners, there are no
outstanding or unfulfilled requirements or recommendations of any insurance
company insuring any Company regarding any repairs to or work to be performed
with respect to the assets of such Company.  Each Company has complied with any
such requirements and recommendations as to which the Company has received
notice.  Schedule 5.16 contains a listing of all claims made and loss histories
in respect of any insurance maintained by each Company or any predecessor
during the past three (3) years.

the assets of any Company may suffer or be subjected to any lien, encumbrance
or restriction of any nature, or (b) any noncompliance with any federal, state
or local environmental law, rule, regulation or order as a result of or in
connection with any of the foregoing.

     5.18 Accounts Receivable and Payable.  To the knowledge of the Companies
and the Owners, except as set forth on Schedule 5.18.1, the accounts receivable
outstanding as of the Effective Time will be subject to no defenses,

accounts payable of any Company will be over 45 days old at any Closing Date,

federal, state and local tax returns and tax reports required to be filed prior
to the date hereof with respect to any Company have been filed (other than

Revenue Service (the "IRS") or the appropriate state agencies for any fiscal
year or period ended prior to the date hereof, and no Company is presently
under, nor has received notice of any, contemplated investigation or audit by
the IRS or any state agency concerning any fiscal year or period ended prior to
the date hereof.  Except as listed on Schedule 5.19, no Company has executed
any extension or waivers of any statute of limitations on the assessment or
collection of any tax due that is currently in effect.

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

     (d) From its inception, each Member has been a validly electing S
corporation as defined in Section 1361 of the Code and corresponding provisions
of state and local income tax law in all jurisdictions in which it is required
to report its business operations.  No Member or Owner has received any notice
from the IRS challenging such status and no Member or Owner is aware of any
circumstances that would be a basis for challenging such status.

     (f) The Owners shall cause to be prepared and filed, at their expense, a
short period tax return of each Company ending on the Closing Date.  Such
returns shall be provided for RCG's prior review and approval, which approval

corporation for that short period for each Member and as a partnership for
RenalWest.  RCG shall make available any information in its or the Companies'
possession which is reasonably required by the Owners to complete such returns
at no cost to the Owners.

     (g) Except as disclosed on Schedule 5.19, there is no liability for taxes

current or a future taxable period, (ii) that is wholly or partly a consequence
of a transaction or occurrence, or transactions or occurrences, one or more of
which occurred before the date hereof, and (iii) that is not fully reserved on
the Financial Statements.  In addition, except as disclosed on Schedule 5.19,
there are no joint venture, partnership or other arrangements or contracts to
which any Company or any of their subsidiaries is a party and that could be
treated as a partnership for federal income tax purposes.

     (h) For purposes hereof, "taxes" shall mean any federal, state, county,
local, foreign or other tax, charge, imposition or other levy (including
interest or penalties thereon) including without limitation, income taxes

     5.20 Licenses, Authorizations and Provider Programs.  (a)  Each Company is
the holder of all valid licenses and other rights and authorizations required
by law, ordinance, regulation or ruling of any governmental regulatory
authority necessary to operate its business.  RenalWest is certified for
participation and reimbursement under Titles XVIII and XIX of the Social

referred to collectively as the "Government Programs") and has current provider

which the Company directly or indirectly is presently receiving payments (such
non-governmental programs herein referred to as "Private Programs").  Set forth

violation, default, order or deficiency exists with respect to any of the items
listed on Schedule 5.20.1.  None of the Companies or the Owners has received
any notice of any action pending or recommended by any state or federal
agencies having jurisdiction over the items listed on Schedule 5.20.1, either
to revoke, withdraw or suspend any license, right or authorization, or to
terminate the participation of any Company in any Government or Private
Program.  To the knowledge of the Companies and the Owners, no event has
occurred which, with the giving of notice, the passage of time, or both, would
constitute grounds for a material violation, order or deficiency with respect
to any of the items listed on Schedule 5.20.1 or to revoke, withdraw or suspend
any such license, or to terminate or modify the participation of any Company 



                                   - 12 -

the Owners, there has been no decision not to renew any provider or 
third-party payor agreement of any Company.  Except as listed on Schedule
5.20.2, no consent or approval of, prior filing with or notice to, or any
action by, any governmental body or agency or any other third party is required
in connection with any such license, right or authorization, or Government or
Private Program, by reason of the consummation of the Mergers, and the
continued operation of the business of the Companies thereafter on a basis
consistent with past practices.

     (c) Each Company has timely filed all cost reports and other reports
required to be filed by it prior to the date hereof with respect to the
Government and Private Programs, all fiscal intermediaries and other insurance
carriers and all such reports are complete and accurate in all material
respects and have been prepared in material compliance with all applicable
laws, regulations, and principles governing reimbursement and payment claims.
True and complete copies of such cost reports filed by each Company for the
most recent cost-reporting year, if applicable, have heretofore been delivered

in the Financial Statements all known and undisputed refunds, overpayments,
discounts or adjustments which have become due pursuant to such reports and has
no liability under any Government or Private Program (known or unknown,
contingent or otherwise) for any refund, overpayment, discount or adjustment
other than in the ordinary course, and no interest or penalties accruing with
respect thereto, except as has been specifically reserved for in the Financial
Statements or disclosed herein or in the Schedules hereto.  To the knowledge of
the Companies and Owners, except as set forth on Schedule 5.20.3, there are no
pending appeals, adjustments, challenges, audits, litigation, or notices of
intent to reopen any closed cost reports.  There are no other reports required
to be filed by any Company in order to be paid under any Government or Private
Program for services rendered, except for cost reports not yet due.

     5.21 Inspections and Investigations.  Except as set forth and described in
Schedule 5.21, (i) neither any of the Company's right nor, to the knowledge of

affected as a result of any investigation or action whether by any federal or
state governmental regulatory authority or other third party, (ii) no Company,

individual, nor has any Company received any notice of deficiency during the
past three years in connection with its operations, (iii) there are not
presently, and at the Effective Time there will not be, any outstanding
deficiencies or work orders of any governmental authority having jurisdiction
over any Company, or other third party, requiring conformity to any applicable

to, the Government and Private Programs, and (iv) there is not any notice of
any claim, requirement or demand of any licensing or certifying agency or other
third party supervising or having authority over any Company or their
operations to rework or redesign any part thereof or to provide additional
furniture, fixtures, equipment, appliances or inventory so as to conform to or
comply with any existing law, code, rule, regulation or standard.  Attached as

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

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

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

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


                                     - 25 -



<PAGE>   178


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

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

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

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

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

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

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


                                   - 26 -


<PAGE>   179

shall not apply to any a transaction in which the Owner's medical practice  
would join the multispecialty physician group from which the Owner's
practice has received substantially all of its patient referrals.  RCG or any
of its affiliates may accept the offer by giving written notice of such
acceptance at any time within 20 days following receipt of written notice of
the offer. No activities of any Owner under this Section 8.10 shall be deemed a
violation of Section 8.8 hereof.

     8.11 Delivery of Schedules.  As soon as reasonably practical following the
execution hereof, the Companies and the Owners shall deliver all Schedules to
be delivered by them to RCG and its counsel accompanied by a certificate,
executed by the Companies and the Owners stating that all Schedules required to
be delivered by them hereunder have been delivered.  The Companies and the
Owners understand and acknowledge that RCG's obligation to consummate the
Closing is subject to its satisfactory review of said Schedules as contemplated
by Section 9.6 hereof.  After receipt of all such Schedules and the
certificate, RCG shall complete its review of said Schedules and notify the
Company of its satisfaction with said Schedules at least ten (10) days prior to
Closing.

     8.12 Availability of Rule 144 Information.  For so long as RCG is subject
to the 1934 Act, RCG shall take all actions necessary to enable the Owners to
sell any shares of RCG Stock received by them without registration under the
1933 Act within the limitations of the exemption provided by Rule 144 under the
1933 Act, as such rule may be amended from time to time, or any similar rule or
regulation hereafter adopted by the Securities and Exchange Commission,
including filing on a timely basis all reports required to be filed by the 1934
Act.  Upon the request of an Owner, RCG shall deliver to such Owner a written
statement as to whether it has complied with such requirements.

     8.13 Approval of Transactions.  Subject to Article 11 hereof, each Owner,
through the execution and delivery of this Agreement, irrevocably votes for and
approves the Merger in its capacity as a holder of Company Equity Securities
and each such Owner does hereby waive any required notice for any meeting
concerning such matters.  Subject to Article 11 hereof, at any further meeting
of the Owners of the Company called to vote on the Mergers or in any other
circumstances upon which a vote, consent or other approval with respect to the
Mergers is sought, such Owner shall vote (or cause to be voted), such Owner's
Company Equity Securities in favor of the Mergers and the execution, delivery
and performance by the Companies of the Merger Documents.  Each Owner
acknowledges and agrees that he, she or it has had adequate opportunity to
review the terms and conditions of the Mergers and to seek independent legal,
tax and financial advice.

     8.14 Accounting and Tax Treatment.  Each of the parties undertakes and
agrees to use its reasonable efforts to cause the Mergers, and to take no
action which would cause the Mergers not, to qualify for pooling-of-interests
accounting treatment and treatment as a "reorganization" within the meaning of
Section 368(a) of the Code for federal income tax purposes.  Each Owner agrees
that he will not sell, transfer, or otherwise dispose of his interests in, or
reduce his risk relative to, any of the shares of RCG Common Stock into which
his shares of Company Common Stock are converted upon consummation of the
Merger until such time as the requirements of SEC Accounting Series Release
Nos. 130 and 135 ("ASR 130 and 135") have been met.  Each Owner understands
that ASR 130 and 135 relate to publication of financial results of post-Merger
combined operations of RCG and the Companies.  RCG agrees to promptly notify
the Owners following satisfaction of the requirements of ASR 130 and 135.

     8.15 Resignation and Releases.  Simultaneously with the execution and
delivery of this Agreement, each officer, director and Owner of the Companies
shall deliver a Resignation and Release, to be effective as of the Closing, in
the form of Exhibit 8.15 to this Agreement.

     8.16 Representations on RCG Board of Directors and Medical Advisory Board.
RCG agrees that it shall at the Closing increase the number of members to its
Board of Directors by one and add an individual specified by the Companies as a
new member, with such member subject to the reasonable approval of RCG, to
serve an initial term ending on the date of RCG's 1999 Annual Meeting of its
stockholders.  Further, RCG shall recommend to its stockholders at such 1999
Annual Meeting that such

who shall be subject to the reasonable approval of RCG, as a member of RCG's
Medical Advisory Board.

     8.17 Grant of Options.  At Closing, RCG shall grant options to purchase an

Such options shall (i) to the extent possible be granted under RCG's 1996 Stock

mutually agreed with RCG prior to the Closing, (iv) vest over a five-year

Mesa, Arizona, will serve as the executive headquarters of RCG's southwest

RenalWest earned prior to the Closing shall be distributed to the Members and
that the Members shall distribute such income to the Owners.  Such
distributions by RenalWest shall be made in accordance with the respective
ownership interests therein of the Members and such distributions to the Owners

of which shall be consistent with past practices.  The Owners agree that they

Party may settle or compromise such claim without the Indemnifying Party's

Indemnifying Party for this purpose) shall be required to indemnify the
Indemnified Party (with the Owners as a group deemed as a single Indemnifying
Party for this purpose) unless the amount of the loss or claim for which
indemnification is sought, when aggregated with all other losses and claims for
which indemnification is sought by the Indemnified Party (with the Owners as a
group deemed as a single Indemnifying Party for this purpose), exceeds
$200,000, at which time rights to indemnification for losses and claims may be
asserted for any amounts in excess of $200,000.

     12.5 Indemnification Limit.

solely and exclusively by means of delivery by the Indemnifying Party to the
Indemnified Party of shares of RCG Common Stock whose Average Trading Price
equals the amount for which the Indemnified Party is entitled to be
indemnified, provided that the Owners shall be obligated to satisfy their
indemnification obligation in cash to the extent that they no longer hold a
sufficient number of shares of RCG Common Stock to satisfy their obligation.

     12.6 Survival, Exclusivity and Insurance.  The representations and
warranties of the parties contained in the Merger Documents or in any document
or instrument delivered in connection therewith shall survive the Closing and

set forth in this Article 12 shall constitute the sole and exclusive remedy for
any inaccuracy or breach of any such representation or warranty.  The
limitations contained in this Article 12 shall not apply to fraud or
intentional misrepresentation.

such RCG Common Stock and (ii) the term "Holder" means the Owners or a
transferee of Registrable Securities to which the Owners may transfer their

conditions as granted by RCG to its existing stockholders (the "Founding
Stockholders"), a copy of which registration rights is attached hereto as

                                   - 34 -


<PAGE>   187


        (i) RCG will undertake reasonable commercial efforts to file a
registration statement for the Secondary Offering described in Section 1.2(a)
of Appendix A with the SEC by November 30, 1996 and thereafter to take
reasonable commercial efforts to have said registration statement declared
effective by the SEC as soon as practicable.

        (ii) To the extent permissible under the "pooling of interests" rules
described in Section 8.14 of this Agreement, the Owners shall have the right to
include up to forty percent (40%) of their aggregate Registrable Securities in
any such Secondary Offering, provided that said Registrable Securities are
allocated among the Owners in a manner reasonably acceptable to RCG.

        (iii) The Owners, acting by a majority in interest, shall have the
right independently to elect the demand registration rights described in
Section 1.2(a) of Appendix A and shall have the right to include up to twenty
percent (20%) of their Registrable Securities in any such demand registration.

Registrable Securities, as said Rule may be amended after the date hereof.

        (v) Notwithstanding Section 1.2(c) of Appendix A, if Holders (i.e.,
Owners and their transferees as defined in this Agreement) proposing to
distribute their Registrable Securities shall be prevented from including at
least eighty percent (80%) of the Registrable Securities proposed to be

demand registration pursuant to Section 1.2 upon the request of Holders.

        (vi) Notwithstanding Section 1.3 of Appendix A, the Holders shall have

        (vii) Notwithstanding Section 1.9 of Appendix A, any Holder's
registration rights hereunder may be assigned to a permitted transferee or
assignee of Registrable Securities, provided that RCG is given written notice
by such Holder at the time of or within a reasonable time of after such
transfer, stating the name and address of said transferee or assignee and
identifying the Registrable Securities with respect to which such registration
rights are being assigned.  Any transferee shall, as a condition of such
transfer, agree that all transferred Registrable Securities are subject to the
terms, conditions, provisions and agreement of this Agreement.

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

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

        (b) Any party hereto may change its address specified for notices
herein by designating a new address by notice in accordance with this Section
15.1.

     15.2 Owner's Representative.  (a)  The Owners have and do hereby
irrevocably make, constitute and appoint Jeff Weintraub as their agent (the
"Owner's Representative") and authorize and empower him to fulfill the role of
Owner's Representative hereunder.  In the event of the resignation of the
Owner's Representative, the resigning Owner's Representative shall appoint a
successor from among the Owners and who shall agree in writing to accept such
appointment.  If the Owner's Representative should die or become incapacitated,
his successor shall be appointed within 15 days of his death or incapacity by a
majority of the Owners, and such successor shall be a Owner.  The choice of a
successor Owner's Representative appointed in any manner permitted above shall
be final and binding upon all of the Owners.  The decisions and actions of any
successor Owner's Representative shall be, for all purposes, those of a Owner's
Representative as if originally named herein.

        (b) Each Owner has made, constituted and appointed and by the execution
of this Agreement hereby irrevocably makes, constitutes and appoints the
Owner's Representative as such person's true and lawful attorney in fact and
agent, for such person and in such person's name, place and stead for all
purposes necessary or desirable in order for the Owner's Representative to take
the actions contemplated by

the Merger Documents on behalf of the Owners, with the ability to execute and
deliver all instruments, certificates and other documents of every kind
incident to the foregoing to all intents and purposes and with the same effect
as such Owner could do personally, and each such Owner hereby ratifies and
confirms as his, her, or its own act, all that the Owner's Representative shall
do or cause to be done pursuant to the provisions hereof.  All Claim Notices
and all other notices and communications directed to Owners under this
Agreement shall be given to the Owner's Representative.

        (c) The death or incapacity of any Owner shall not terminate the
authority and agency of the Owner's Representative.

        (d) The Owners hereby agree to indemnify the Owner's Representative and
to hold him or her harmless against any and all loss, liability or expense
incurred without bad faith on the part of the Owner's Representative and
arising out of or in connection with his or her duties as Owner's
Representative, including the reasonable costs and expenses incurred by the
Owner's Representative in defending against any claim or liability in
connection herewith.

     15.3 Expenses.  Each of the parties hereto shall bear and pay all costs
and expenses incurred by it or on its behalf in connection with the
transactions contemplated hereunder, provided, however, all legal, accounting
and other fees and expenses incurred by the Companies and the Owners concerning
the transactions contemplated hereby in excess of $150,000 shall be paid by the
Owners at the Closing or thereafter when due.

     15.4 Further Assurances.  Each party covenants that at any time, and from
time to time, after the Closing, it will execute such additional instruments
and take such actions as may be reasonably requested by the other parties to
confirm or perfect or otherwise to carry out the intent and purposes of this
Agreement.

     15.5 Waiver.  Any failure on the part of any party to comply with any of
its obligations, agreements or conditions hereunder may be waived by any other
party to whom such compliance is owed.  No waiver of any provision of this
Agreement shall be deemed, or shall constitute, a waiver of any other
provision, whether or not similar, nor shall any waiver constitute a continuing
waiver.

     15.6 Assignment.  This Agreement shall not be assignable by any of the
parties hereto without the written consent of all other parties.

     15.7 Binding Effect.  This Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective heirs, legal
representatives, executors, administrators, successors and assigns.  This
Agreement shall survive the Closing and not be merged therein.

     15.8 Headings.  The section and other headings in this Agreement are
inserted solely as a matter of convenience and for reference, and are not a
part of this Agreement.

     15.9 Entire Agreement.  This Agreement and the Exhibits, Schedules,
certificates and other documents delivered pursuant hereto or incorporated
herein by reference, contain and constitute the entire agreement among the
parties and supersede and cancel any prior agreements, representations,
warranties, or communications, whether oral or written, among the parties
relating to the transactions contemplated by this Agreement.  Neither this
Agreement nor any provision hereof may be changed, waived, discharged or
terminated orally, but only by an agreement in writing signed by the party
against whom or which the enforcement of such change, waiver, discharge or
termination is sought.

     15.10 Governing Law; Severability.  This Agreement shall be governed by
and construed in accordance with the Laws of the State of Delaware, without
regard to any applicable conflicts of Laws; provided, however, that the
effectiveness and validity of the Mergers and Section 8.7 hereof shall be
governed by the Laws of the State of Arizona.  The provisions of this Agreement
are severable and the

invalidity of one or more of the provisions herein shall not have any effect
upon the validity or enforceability of any other provision.

     15.11 Counterparts.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

     15.12 No Brokers.  The Owners, the Companies and RCG each represent to the
others that no broker or finder has been employed in connection with the
transactions hereunder.

     15.13 Schedules and Exhibits.  All Schedules and Exhibits attached to this
Agreement are by reference made a part hereof.

stockholders of Renal Care Group, Inc. (the "Company") from a financial point of
view, of the consideration to be paid by them pursuant to an Agreement and Plan
of Merger dated as of August 7, 1996 (the "Merger Agreement"), involving the
Company and RENALWEST, L.C. ("RenalWest"). Pursuant to the terms of the Merger
Agreement, RenalWest will become a wholly owned second-tier subsidiary of the
Company by means of the merger (the "Merger") of three wholly owned subsidiaries
of the Company into 3-CO, Inc., 4-CO, Inc., and 9-CO, Inc., the three members of
RenalWest (the "Members"), and the issuance of an aggregate of 2,400,000 shares
of the Company's common stock to the shareholders of the Members upon
consummation of the Merger. The Merger is expected to be tax-free to the
shareholders of RenalWest and will be accounted for as a pooling of interests.
    
 
   
     In arriving at our opinion, we have reviewed certain publicly available
business and financial information relating to the Company and RenalWest. We
have reviewed certain other information, including financial forecasts and other
internal financial analyses, provided to us by the Company and RenalWest, and we
have met with the managements of both the Company and RenalWest to discuss the
business prospects of their respective companies and the joint prospects of a
combined company. In addition, we have: (i) reviewed the reported price and
trading activity for the common stock of the Company; (ii) compared certain
financial and stock market information for the Company and RenalWest with
similar information for certain other comparable companies whose securities are
publicly traded; and (iii) performed such other studies and analyses as we
considered appropriate.
    
 
     We have assumed and relied upon, without independent verification, the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the financial projections used in our analyses, we
have assumed that they have been reasonably prepared on bases reflecting the
best currently available estimates and judgments of the respective senior
managements of the Company and RenalWest as to the likely future financial
performance of their respective companies. In addition, we have not made an
independent valuation or appraisal of the assets of the Company or RenalWest.
Our opinion is based on market, economic, and other conditions as they exist and
can be evaluated as of the date of this letter.
 
   
     Equitable Securities Corporation has acted as financial advisor to the
Company in connection with the Merger and has received a fee for rendering this
opinion, a portion of which is contingent upon the consummation of the Merger.
We regularly publish research reports regarding the health care industry and the
businesses and securities of publicly owned companies in that industry,
including the Company. We own for
    
 
<PAGE>   197
 
   
investment 30,763 shares of the Company's common stock and securities
exercisable or convertible into 66,667 shares of the Company's common stock. We
acted as managing underwriter in February 1996 in connection with the Company's
initial public offering of common stock, and we received customary compensation
for our services. In the ordinary course of our business as broker-dealers, we
maintain a market in and actively trade the common stock of the Company for our
own account and for the accounts of customers and, accordingly, may at any time
hold a long or short position in such securities.
    
 
   
     Based on the analysis described above and subject to the foregoing
limitations and qualifications, it is our opinion that, as of the date hereof,
the consideration to be issued by the Company pursuant to the Merger Agreement
is fair from a financial point of view to the Company's shareholders.
    
 
     It is understood that this letter is for the information of the Board of
Directors of the Company and is not to be quoted or referred to, in whole or in
part, without our written consent; provided, however, that we hereby consent to
the inclusion of this opinion in any registration or proxy statement used in
connection with the Merger, so long as the opinion is quoted in full in such
registration or proxy statement.
 
   
Very truly yours,

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

                                 STOCK OPTIONS
 
     7.1. GENERAL.  The Committee is authorized to grant Options to Participants
on the following terms and conditions:
 
          (a) Exercise Price.  The exercise price per share of Stock under an
     Option shall be determined by the Committee. The Committee may elect to
     grant Non-Qualified Stock Options with an exercise price per share of Stock
     less than the Fair Market Value of a share of Stock on the date any such
     Non-Qualified Stock Option is granted.
 
          (b) Time and Conditions of Exercise.
 
             (i) The Committee shall determine the time or times at which an
        Option may be exercised in whole or in part. The Committee also shall
        determine the performance or other conditions, if any, that must be
        satisfied before all or part of an Option may be exercised.
 
             (ii) In connection with the grant of any Options, the Committee may
        provide in the Option Agreement for the termination of all or any
        portion of the Options under certain circumstances, including, without
        limitation, termination of a Participant's employment, provided that the
        Committee may distinguish among various causes of termination as the
        Committee deems appropriate. In
 
                                        4
<PAGE>   202
 
        addition, the Committee may provide, through the Option Agreement or
        otherwise, that if a Participant's employment is terminated: (i) such
        Participant's Option(s) may be exercised for specified periods
        thereafter but no later than the expiration date of such Option; (ii) to
        the extent not fully exercisable on the date of termination of
        employment, such Option may continue to become exercisable within the
        term of the Option; or (iii) some or all of the Options not fully
        exercisable on the date of termination of employment may be deemed fully
        exercisable. A Participant's employment shall be deemed to terminate on
        the last date for which he or she receives a regular wage or salary
        payment (excluding severance payments unless otherwise provided in the
        Option Agreement). Whether military, government or other service or
        other leave of absence shall constitute a termination of employment
        shall be determined in each case by the Committee at its discretion, and
        any determination by the Committee shall be final and conclusive. A
        termination of employment shall not occur where the Participant
        transfers from the Company to one of its Subsidiaries, transfers from a
        Subsidiary to the Company or transfers from one Subsidiary to another
        Subsidiary.
 
          (c) Payment.  The Committee shall determine the methods by which the
     exercise price of an Option may be paid, the form of payment, including,
     without limitation, cash, shares of Stock, or other property (including
     "cashless exercise" arrangements), and the methods by which shares of Stock
     shall be delivered or deemed to be delivered to Participants. Without
     limiting the power and discretion conferred on the Committee pursuant to
     the preceding sentence, the Committee may, in the exercise of its
     discretion, but need not, allow a Participant to pay the exercise price of
     an Option by directing the Company to withhold from the shares of Stock
     that would otherwise be issued upon exercise of the Option that number of
     shares having a Fair Market Value on the exercise date equal to the
     exercise price, all as determined pursuant to rules and procedures
     established by the Committee.
 
          (d) Evidence of Grant.  All Options shall be evidenced by a written
     Option Agreement between the Company and the Participant. The Option
     Agreement shall include such provisions as may be specified by the
     Committee.
 
     7.2. INCENTIVE STOCK OPTIONS.  The terms of any Incentive Stock Options
granted under the Plan must comply with the following additional rules:
 
          (a) Exercise Price.  The exercise price per share of Stock shall be
     set by the Committee, provided that the exercise price for any Incentive
     Stock Option shall not be less than the Fair Market Value as of the date of
     the grant.
 
          (b) Exercise.  In no event may any Incentive Stock Option be
     exercisable for more than ten years from the date of its grant.
 
          (c) Individual Dollar Limitation.  The aggregate Fair Market Value
     (determined as of the time an Option is made) of all shares of Stock with
     respect to which Incentive Stock Options are first exercisable by a
     Participant in any calendar year may not exceed $100,000.
 
          (d) Ten Percent Owners.  No Incentive Stock Option shall be granted to
     any individual who, at the date of grant, owns stock possessing more than
     ten percent of the total combined voting power of all classes of stock of
     the Company or any Subsidiary unless the exercise price per share of such
     Option is at least 110% of the Fair Market Value per share of Stock at the
     date of grant and the Option expires no later than five years after the
     date of grant.
 
          (e) Expiration of Incentive Stock Options.  No award of an Incentive
     Stock Option may be made pursuant to the Plan on or after the tenth
     anniversary of the Effective Date.
 
          (f) Right To Exercise.  During a Participant's lifetime, an Incentive
     Stock Option may be exercised only by the Participant.
 
          (g) Interpretation of Incentive Stock Options.  In interpreting this
     Section 7.2 of the Plan and the provisions of individual Option Agreements
     granting Incentive Stock Options, the Committee shall be
 
                                        5
<PAGE>   203
 
     governed by the principles and requirements of Sections 421, 422 and 424 of
     the Code, and applicable Treasury Regulations.

                    GENERAL PROVISIONS APPLICABLE TO OPTIONS
 
     8.1. STAND-ALONE, TANDEM, AND SUBSTITUTE OPTIONS.  Options granted under
the Plan may, in the discretion of the Committee, be granted either alone or in
addition to, in tandem with, or in substitution for, any other Option granted
under the Plan. If an Option is granted in substitution for another Option, the
Committee may require the surrender of such other Option in consideration of the
grant of the new Option. Options granted in addition to or in tandem with other
Options may be granted either at the same time as or at a different time from
the grant of such other Options.
 
     8.2. EXCHANGE PROVISIONS.  The Committee may at any time offer to exchange
or buy out any previously granted Option for a payment in cash, Stock, or
another Option (subject to Section 8.1), based on the terms and conditions the
Committee determines and communicates to the Participant at the time the offer
is made.
 
     8.3. TERM OF OPTION.  The term of each Option shall be for the period as
determined by the Committee, provided that in no event shall the term of any
Incentive Stock Option exceed a period of ten years from the date of grant.
 
     8.4. LIMITS ON TRANSFER.  No right or interest of a Participant in any
Option may be pledged, encumbered, or hypothecated to or in favor of any party
other than the Company or a Subsidiary, or shall be subject to any lien,
obligation, or liability of such Participant to any other party other than the
Company or a Subsidiary. No Option shall be assignable or transferable by a
Participant other than by will or the laws of descent and distribution or,
except in the case of an Incentive Stock Option, pursuant to a domestic
relations order as defined in Section 414(p)(1)(B) of the Code, if the order
satisfies Section 414(p)(1)(A) of the Code.
 
     8.5. STOCK CERTIFICATES.  All Stock certificates delivered under the Plan
are subject to any stop-transfer orders and other restrictions as the Committee
deems necessary or advisable to comply with federal or state securities laws,
rules and regulations and the rules of any national securities exchange or
automated quotation system on which the Stock is listed, quoted, or traded. The
Committee may place legends on any Stock certificate to reference restrictions
applicable to the Stock.
 
     8.6. CHANGES IN CONTROL.
 
          (a) Change in Control Followed by Employment Termination.  In the
     event that a Change in Control shall occur and an employee Participant's
     employment shall terminate, except as provided in the next sentence, within
     twelve (12) months after the Change in Control, then (i) all unexercised
     Options (whether vested or not vested) shall automatically become one
     hundred percent (100%) vested immediately, (ii) no other terms, conditions,
     restrictions or limitations shall be imposed upon any such Options after
     such date, and in no circumstance shall an Option be forfeited on or after
     such date, and (iii) all such Options shall be valued on the basis of the
     greater of the Change in Control Price or the Fair Market Value on the date
     of such termination, and such value shall promptly be paid to the
     Participant in cash by the Company or its successor. The foregoing shall
     not apply if employment termination is due to (i) death, (ii) disability
     entitling the Participant to benefits under the Company's or its
     successor's long-term disability plan, (iii) Cause, or (iv) resignation
     (other than (A) resignation from a declined reassignment to a job that is
     not reasonably equivalent in responsibility or compensation or that is not
     in the same geographic area, or (B) resignation within 30 days following a
     reduction in base pay).
 
          (b) Automatic Acceleration and Cash-Out.  Upon a Change in Control
     that results directly or indirectly in the Stock (or the stock of any
     successor to the Company received in exchange for Stock) ceasing to be
     publicly traded in a national securities market, (i) all unexercised
     Options (whether vested or not vested) shall automatically become one
     hundred percent (100%) vested immediately, (ii) no other
 
                                        6
<PAGE>   204
 
     terms, conditions, restrictions or limitations shall be imposed upon any
     such Options after such date, and in no circumstance shall an Option be
     forfeited on or after such date, and (iii) all such Options shall be valued
     on the basis of the Change in Control Price, and such value shall promptly
     be paid to the Participant in cash by the Company or its successor.
 
          (c) Miscellaneous.  Upon a Change in Control, no action, including,
     without limitation, the amendment, suspension or termination of the Plan,
     shall be taken that would adversely affect the rights of any Participant or
     the operation of the Plan with respect to any Option to which a Participant
     may have become entitled hereunder on or prior to the date of the Change in
     Control or to which such Participant may become entitled as a result of
     such Change in Control.
 
     8.7. MODIFICATION, EXTENSION AND RENEWAL.  The Committee may modify, renew
or accept the surrender of outstanding Options issued under the Plan (or the
surrender of similar grants issued under any other plan of the Company or a
Subsidiary), including the acceleration or waiver of any vesting or other
restrictions or limitations, or the conversion of such Options (with appropriate
adjustments) to be applicable to the securities of any successor corporation to
the Company, and the Committee may authorize new Options pursuant to the Plan in
substitution for any outstanding Options. Any substituted, modified or converted
Options may bear such different or additional terms and conditions as the
Committee shall deem appropriate within the limitations of the Plan. The
determination of the Committee as to the terms of any of the foregoing may be
made without regard to whether a Change in Control has or has not occurred (or
whether the Committee has determined that any event shall not be considered to
be a Change in Control) and shall be conclusive and binding notwithstanding the
provisions of the respective agreements regarding exercisability. Any fractional
shares resulting from any of the foregoing adjustments under this Section shall
be disregarded and eliminated. However, no modification of an Option shall,
without the consent of the Participant holding the Option, adversely affect the
rights or obligations of such Participant with respect to such Option.
 
                                   ARTICLE 9
 
                          CHANGES IN CAPITAL STRUCTURE
 
     9.1. GENERAL.  If the Company's outstanding shares of Stock are increased
or decreased or changed into or exchanged for a different number or kind of
shares or other securities of the Company by reason of any recapitalization,
reclassification, stock split, combination of shares, stock dividend, or
transaction having similar effect, the Board shall proportionately and
appropriately adjust (i) the number of shares of Stock authorized and reserved
for grants under the Plan as set forth in Section 5.1, (ii) the number of shares
of Stock that may be subject to one or more Options granted to any one
Participant in any one taxable year as set forth in Section 5.4, and (iii) the
number and kind of shares that are subject to each Option and the exercise price
per share, without any change in the aggregate price to be paid therefor upon
exercise of each Option.
 
                                   ARTICLE 10
 
                    AMENDMENT, MODIFICATION AND TERMINATION
 
     10.1. AMENDMENT, MODIFICATION AND TERMINATION.  With the approval of the
Board, at any time and from time to time, the Committee may terminate, amend or
modify the Plan without stockholder approval; provided, however, that the
Committee may condition any amendment on the approval of stockholders of the
Company if such approval is necessary or deemed advisable with respect to tax,
securities or other applicable laws, policies or regulations.
 
     10.2 OPTIONS PREVIOUSLY GRANTED.  No termination, amendment, or
modification of the Plan shall adversely affect any Option previously granted
under the Plan, without the written consent of the Participant.

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

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