ITEM 5. OTHER EVENTS.

         On May 2, 1997, the Board of Directors of Renal Care Group, Inc. (the
"Corporation") declared a dividend of one preferred stock purchase right (a
"Right") for each outstanding share of common stock, par value $0.01 per share
(the "Common Shares"), of the Corporation. The dividend is payable on June 2,
1997 (the "Record Date") to the stockholders of record on that date. Each Right
entitles the registered holder to purchase from the Corporation one
one-hundredth of a share of Series A Junior Participating Preferred Stock, par
value $0.01 per share (the "Preferred Shares"), of the Corporation, at a price
of $140 per one one-hundredth of a Preferred Share (the "Exercise Price"),
subject to adjustment. The description and terms of the Rights are set forth in
the Shareholder Protection Rights Agreement, as the same may be amended from
time to time (the "Rights Agreement"), dated as of May 2, 1997 between the
Corporation and First Union National Bank of North Carolina, as Rights Agent
(the "Rights Agent").

Separation Time

         Until the date on which certain events take place (the "Separation
Time"), the Rights will be evidenced by, with respect to any Common Share
certificate outstanding on the Record Date, such Common Share and a Summary of
Rights mailed to each holder of record on the Record Date. The term "Separation
Time" means the close of business on the earlier of (a) the tenth business day
(or such earlier or later date as may be determined by the Board of Directors of
the Corporation) following a public announcement by the Corporation that a
person or group of affiliated or associated persons has acquired beneficial
ownership of 15% or more of the outstanding Common Shares (collectively, an
"Acquiring Person") (the "Flip-in Date") or (b) the tenth business day (or
such later date as may be determined by the Board of Directors of the
Corporation) after the date on which any person or group of affiliated or
associated persons commences a tender or exchange offer the consummation of
which would result in the beneficial ownership by such Person of 15% or more of
such outstanding Common Shares.

Transfer of Rights and Certificates

         The Rights Agreement provides that, until the Separation Time, the
Rights will be transferred with and only with the Common Shares. Until the
Separation Time (or the earlier termination or expiration of the Rights), new
Common Share certificates issued after the Record Date upon transfer or new
issuance of Common Shares will contain a notation incorporating the Rights
Agreement by reference. Until the Separation Time (or the earlier termination or
expiration of the Rights), the surrender for transfer of any certificates for
Common Shares outstanding as of the Record Date, even without such notation,
will also constitute the transfer of the Rights associated with the Common
Shares represented by such certificate. As soon as practicable following the
Separation Time, separate certificates evidencing the Rights (the "Right
Certificates") will be mailed to holders of record of the Common Shares as of
the close of business on the Separation Time, and such separate Right
Certificates alone will evidence the Rights.


                                      -2-
<PAGE>   3
Exercise Period

         The Rights are not exercisable until the Separation Time. After the
Separation Time and prior to the Expiration Time, each Right (unless previously
terminated) will entitle the holder to purchase, for the Exercise Price, one
one-hundredth of a share of the Preferred Shares having the rights described
below. The Rights will expire on the Expiration Time, unless the Expiration Time
is extended, or the Rights are earlier terminated by the Corporation. The term
"Expiration Time" is defined in the Rights Agreement and generally means May
2, 2007, unless the Rights are sooner exchanged or terminated.

Adjustments

         The Exercise Price payable, and the number of outstanding Rights and
the number of one one-hundredth interests in Preferred Shares issuable upon
exercise of each Right, are subject to adjustment in the event of a stock split
of the Common Shares or a stock dividend on the Common Shares payable in Common
Shares or subdivisions, consolidations or combinations of the Common Shares
occurring, in any such case, prior to the Separation Time.

         If prior to the Separation Time, the Corporation distributes securities
or assets in exchange for Common Shares (other than regular cash dividends or a
dividend paid solely in Common Shares) whether by dividend, reclassification or
otherwise, the Corporation shall make such adjustments, if any, in the Exercise
Price, number of Rights and otherwise as the Board of Directors deems
appropriate.

Exercise of Rights for Common Stock

         At a Flip-in Date, Rights owned by the Acquiring Person or any
affiliate or associate thereof or any transferee thereof will automatically
become void and, subject to the Exchange Option summarized below, each other
Right will automatically become a right to buy, for the Exercise Price, that
number of Common Shares or, at the option of the Board of Directors, Preferred
Shares designed to have economic and voting terms similar to the Common Shares,
in either case, having a market value of twice the Exercise Price. If any person
or group acquires beneficial ownership of 15% or more of the outstanding Common
Shares without any intent to acquire or affect control of the Corporation, that
acquisition will not result in a Flip-in Date if such acquiror immediately
enters into an irrevocable commitment to promptly divest, and thereafter
promptly divests, sufficient Common Shares so that such 15% or greater
beneficial ownership ceases. After a Flip-in Date occurs, the Corporation may
not consolidate or merge with, or sell 50% or more of its assets or earning
power to, any person, if the Corporation's Board of Directors is controlled by
the Acquiring Person, unless proper provision is made so that each Right would
thereafter become a right to buy, for the Exercise Price, that number of shares
of common stock of such other person having a market value of twice the Exercise
Price.

<PAGE>   4
Optional Exchange of Rights

         At any time after a Flip-in Date occurs and prior to the time a person
or group of persons become the beneficial owner of more than 50% of the
outstanding Common Shares, the Board of Directors of the Corporation may elect
to exchange all of the outstanding Rights (other than Rights owned by such
person or group which have become void), for shares of Common Shares at an
exchange ratio (subject to adjustment) of one Common Share per Right (the
"Exchange Option").

Termination of Rights

         At any time prior to a Flip-in Date, the Board of Directors of the
Corporation may terminate the Rights. Immediately upon any termination of the
Rights, the right to exercise the Rights will terminate.

Amendments

         The Corporation and the Rights Agent may amend the Rights Agreement in
any respect prior to the occurrence of a Flip-in Date. Thereafter, the
Corporation and the Rights Agent may amend the Rights Agreement in any respect
which shall not materially adversely affect the interests of holders of Rights
generally or to cure an ambiguity or to correct or supplement any provision
which may be inconsistent with any other provision or otherwise defective.

Rights Prior to Exercise

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Corporation, including, without limitation, the
right to vote or to receive dividends.

Documents and Effect of This Summary

         A copy of the Rights Agreement is included as an Exhibit to this
Report.  This summary description of the Rights does not purport to be 
complete and is qualified in its entirety by reference to the Rights Agreement,
which is hereby incorporated herein by reference.

                     SHAREHOLDER PROTECTION RIGHTS AGREEMENT


         THIS SHAREHOLDER PROTECTION RIGHTS AGREEMENT (as amended from time to
time, this "Agreement"), is made and entered into as of May 2, 1997, between
Renal Care Group, Inc., a Delaware corporation (the "Company"), and First Union
National Bank of North Carolina, as Rights Agent (the "Rights Agent", which term
shall include any successor Rights Agent hereunder).


                                  WITNESSETH:


         WHEREAS, the Board of Directors of the Company has (a) authorized and
declared a dividend of one right ("Right") in respect of each share of Common
Stock (as hereinafter defined) held of record as of the close of business on 
June 2, 1997 (the "Record Time") and (b) as provided in Section 2.4, authorized
the issuance of one Right in respect of each share of Common Stock issued after
the Record Time and prior to the Separation Time (as hereinafter defined) and,
to the extent provided in Section 5.3, each share of Common Stock issued after
the Separation Time;


         WHEREAS, subject to Sections 3.1, 5.1 and 5.10, each Right entitles the
holder thereof, after the Separation Time, to purchase securities of the Company
(or, in certain cases, of certain other entities) pursuant to the terms and
subject to the conditions set forth herein; and


         WHEREAS, the Company desires to appoint the Rights Agent to act on
behalf of the Company, and the Rights Agent is willing so to act, in connection
with the issuance, transfer, exchange and replacement of Rights Certificates (as
hereinafter defined), the exercise of Rights and other matters referred to
herein;


         NOW THEREFORE, in consideration of the premises and the respective
agreements set forth herein, the parties hereby agree as follows:


                                    ARTICLE I

                               CERTAIN DEFINITIONS

         1.1 Certain Definitions. For purposes of this Agreement, the following
terms have the meanings indicated:


         "Acquiring Person" shall mean any Person who is a Beneficial Owner of
15% or more of the outstanding shares of Common Stock; provided, however, that
the term "Acquiring Person" shall not include any Person (i) who is the
Beneficial owner of 15% or more of the outstanding shares of Common Stock on the
date of this Agreement or who shall become the Beneficial Owner of 15% or more
of the outstanding shares of Common Stock solely as a result of an acquisition
by the Company of shares of Common Stock, until such time hereafter or
thereafter as any of such Person shall become the Beneficial Owner (other than
by means of a stock dividend or stock split) of any additional shares of Common
Stock, (ii) who is the Beneficial owner of 15%, or more of the outstanding
shares of Common Stock but who acquired Beneficial Ownership of shares of Common
Stock without any plan or intention to seek or affect control of the Company, if
such Person promptly enters into an irrevocable commitment promptly to divest,
and thereafter promptly divests (without exercising or retaining any power,
including voting
<PAGE>   3
power, with respect to such shares), sufficient shares of Common Stock (or
securities convertible into, exchangeable into or exercisable for Common Stock)
so that such Person ceases to be the Beneficial owner of 15% or more of the
outstanding shares of Common Stock or (iii) who Beneficially Owns shares of
Common Stock consisting solely of one or more of (A) shares of Common Stock
Beneficially Owned pursuant to the grant or exercise of an option granted to
such Person by the Company in connection with an agreement to merge with, or
acquire, the Company entered into prior to a Flip-In Date, (B) shares of Common
Stock (or securities convertible into, exchangeable into or exercisable for
Common Stock), Beneficially Owned by such Person or its Affiliates or Associates
at the time of grant of such option or (C) shares of Common Stock (or securities
convertible into, exchangeable into or exercisable for Common Stock) acquired by
Affiliates or Associates of such Person after the time of such grant which, in
the aggregate, amount to less than 1% of the outstanding shares of Common Stock.
In addition, the Company, any wholly owned Subsidiary of the Company and any
employee stock ownership or other employee benefit plan of the Company or a
wholly owned Subsidiary of the Company shall not be an Acquiring Person.


         "Affiliate" and "Associate" shall have the respective meanings ascribed
to such terms in Rule 12b-2 under the Securities Exchange Act of 1934, as such
Rule is in effect on the date of this Agreement.


         A Person shall be deemed the "Beneficial Owner", and to have
"Beneficial Ownership" of, and to "Beneficially Own", any securities as to which
such Person or any of such Person's Affiliates or Associates is or may be deemed
to be the beneficial owner of pursuant to Rule 13d-3 and 13d-5 under the
Securities Exchange Act, as such Rules are in effect on the date of this
Agreement as well as any securities as to which such Person or any of such
Person's Affiliates or Associates has the right to become Beneficial Owner
(whether such right is exercisable immediately or only after the passage of time
or the occurrence of conditions) pursuant to any agreement, arrangement or
understanding, or upon the exercise of conversion rights, exchange rights,
rights (other than the Rights), warrants or options, or otherwise; provided,
however, that a Person shall not be deemed the "Beneficial Owner", or to have
"Beneficial Ownership" of, or to "Beneficially Own", any security (i) solely
because such security has been tendered pursuant to a tender or exchange offer
made by such Person or any of such Person's Affiliates or Associates until such
tendered security is accepted for payment or exchange or (ii) solely because
such Person or any of such Person's Affiliates or Associates has or shares the
power to vote or direct the voting of such security pursuant to a revocable
proxy given in response to a public proxy or consent solicitation made to more
than ten holders of shares of a class of stock of the Company registered under
Section 12 of the Securities Exchange Act of 1934 and pursuant to, and in
accordance with, the applicable rules and regulations under the Securities
Exchange Act of 1934, except if such power (or the arrangements relating
thereto) is then reportable under Item 6 of Schedule 13D under the Securities
Exchange Act of 1934 (or any similar provision of a comparable or successor
report). Notwithstanding the foregoing, no officer or director of the Company
shall be deemed to Beneficially Own any securities of any other Person by virtue
of any actions such officer or director takes in such capacity. For purposes of
this Agreement, in determining the percentage of the outstanding shares of
Common Stock with respect to which a Person is the Beneficial Owner, all shares
as to which such Person is deemed the Beneficial Owner shall be deemed
outstanding.


         "Business Day" shall mean any day other than a Saturday, Sunday or a
day on which banking institutions in Nashville, Tennessee are generally
authorized or obligated by law or executive order to close.


         "Close of business" on any given date shall mean 5:00 p.m. Nashville,
Tennessee time on such date (or, if such date is not a Business Day, 5:00 p.m.
Nashville, Tennessee time on the next succeeding Business Day).

case of a Flip-Over Transaction or Event described in clause (i) of the
definition thereof, the Person issuing any securities into which shares of
Common Stock are being converted or exchanged and, if no such securities are

the case of a Flip-Over Transaction or Event referred to in clause (ii) of the
definition thereof, the Person receiving the greatest portion of the assets or

corporation shall be the Flip-Over Entity.


         "Flip-Over Stock" shall mean the capital stock (or similar equity
interest) with the greatest voting power in respect of the election of directors
(or other persons similarly responsible for direction of the business and
affairs) of the Flip-Over Entity.

transactions after a Flip-In Date in which, directly or indirectly, (i) the

consolidation, merger or share exchange, the Acquiring Person Controls the Board
of Directors of the Company and either (A) any term of or arrangement concerning
the treatment of shares of capital stock in such consolidation, merger or share
exchange relating to the Acquiring Person is not identical to the terms and

or Associates or otherwise acting in concert, if, at the time of the entry by
the Company (or any such Subsidiary) into an agreement with respect to such sale
or transfer of assets, the Acquiring Person Controls the Board of Directors of
the 


                                      -3-

2.4 hereof shall have caused the closing prices used to determine the Market
Price on any Trading Days during such period of 20 Trading Days not to be fully
comparable with the closing price on such date, each such closing price so used
shall be appropriately adjusted in order to make it fully comparable with the
closing price on such date. The closing price per share of any securities on
any date shall be the last reported sale price, regular way, or, in case no
such sale takes place or is quoted on such date, the average of the closing bid

securities exchange or quoted by any such organization, the average of the

over-the-counter market, the closing price per share of such securities on such
date shall mean the fair value per share of securities on such date as
determined in good faith by the Board of Directors of the Company, after
consultation with a nationally recognized investment banking firm, and set
forth in a certificate delivered to the Rights Agent.

(i) the tenth business day (or such later date as the Board of Directors of the
Company may from time to time fix by resolution adopted prior to the Separation
Time that would otherwise have occurred) after the date on which any Person
commences a tender or exchange offer which, if consummated, would result in such
Person's becoming an Acquiring Person and (ii) the Flip-In Date; provided, that
if the foregoing results in the Separation Time being prior to the Record Time,
the Separation Time shall be the Record Time and provided further, that if any
tender or exchange offer referred to in clause (i) of this paragraph is
canceled, terminated or otherwise withdrawn prior to the Separation Time without
the purchase of any shares of Common Stock pursuant thereto, such offer shall be
deemed, for purposes of this paragraph, never to have been made.

holder of record of Common Stock as of the Record Time, at such holder's address
as shown by the records of the Company.


         2.2 Legend on Common Stock Certificates. Certificates for the Common
Stock issued after the Record Time but prior to the Separation Time shall
evidence one Right for each share of Common Stock represented thereby and shall
have impressed on, printed on, written on or otherwise affixed to them the
following legend:


         "Until the Separation Time (as defined in the Rights Agreement referred
         to below), this certificate also evidences and entitles the holder
         hereof to certain Rights as set forth in a Rights Agreement, dated as
         of May 2, 1997 (as such may be amended from time to time, the
         "Rights Agreement"), between Renal Care Group, Inc. (the "Company") and
         First Union National Bank of North Carolina, as Rights Agent, the terms
         of which are hereby incorporated herein by reference and a copy of
         which is on file at the principal executive offices of the Company.
         Under certain circumstances, as set forth in the Rights Agreement, such
         Rights may be terminated, may become exercisable for securities or
         assets of the Company or of another entity, may be exchanged for shares
         of Common Stock or other securities or assets of the Company, may
         expire, may become void (if they are "Beneficially Owned" by an
         "Acquiring Person" or an Affiliate or Associate thereof, as such terms
         are defined in the Rights Agreement, or by any transferee of any of the
         foregoing) or may be evidenced by separate certificates and may no
         longer be evidenced by this certificate. The Company will mail or
         arrange for the mailing of a copy of the Rights Agreement to the holder
         of this certificate without charge promptly after the receipt of a
         written request therefor."

Certificates representing shares of Common Stock that are issued and outstanding
at the Record Time shall evidence one Right for each share of Common Stock
evidenced thereby notwithstanding the absence of the foregoing legend.


         2.3 Exercise of Rights; Separation of Rights. (a) Subject to Sections
3.1, 5.1 and 5.10 and subject to adjustment as herein set forth, each Right will
entitle the holder thereof, after the Separation Time and prior to the
Expiration Time, to purchase, for the Exercise Price, one one-hundredth
(1/100th) of a share of Preferred Stock.


         (b) Until the Separation Time, (i) no Right may be exercised and (ii)
each Right will be evidenced by the certificate for the associated share of
Common Stock (together, in the case of certificates issued prior to the Record
Time, with the letter or notice mailed to the record holder thereof pursuant to
Section 2.1) and will be transferable only together with, and will be
transferred by a transfer (whether with or without such letter or notice) of,
such associated share.


         (c) Subject to this Section 2.3 and to Sections 3.1, 5.1 and 5.10,
after the Separation Time and prior to the Expiration Time, the Rights (i) may
be exercised and (ii) may be transferred independent of shares of Common Stock.
Promptly following the Separation Time, the Rights Agent will mail to each
holder of record of Common Stock as of the Separation Time (other than any
Person whose Rights have become void pursuant to Section 3.1(b)), at such
holder's address as shown by the records of the Company (the Company hereby
agreeing to furnish copies of such records to the Rights Agent for this
purpose), (x) a certificate (a "Rights Certificate") in substantially the form
of Exhibit A hereto appropriately completed, representing the number of Rights
held by such holder at the Separation Time and having such marks of
identification or designation and such legends, summaries or endorsements
printed thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Agreement, or as may be required to comply with any
law or with any rule or regulation made pursuant thereto or with any rule or
regulation of any national securities exchange or quotation system on which the
Rights may from time to time be listed or traded, or to conform to usage, and
(y) a disclosure statement describing the Rights.


         (d) Subject to Sections 3.1, 5.1 and 5.10, Rights may be exercised on
any Business Day after the Separation Time and prior to the Expiration Time by
submitting to the Rights Agent the Rights Certificate evidencing such Rights
with an Election to Exercise (an "Election to Exercise" substantially in the
form attached to the Rights Certificate duly completed, accompanied by payment
in cash, or by certified or official bank check or money order payable to the
order of the Company, of a sum equal to the Exercise Price multiplied by the
number of Rights being exercised and a sum sufficient to cover any transfer tax
or charge which may be payable in respect of any transfer involved in the
transfer or delivery of Rights Certificates or the issuance or delivery of
certificates for shares or depository receipts (or both) in a name other than
that of the holder of the Rights being exercised.


         (e) Upon receipt of a Rights Certificate, with an Election to Exercise
accompanied by payment as set forth in Section 2.3(d), and subject to Sections
3.1, 5.1 and 5.10, the Rights Agent will thereupon promptly (i)(A) requisition
from a transfer agent stock certificates evidencing such number of shares or
other securities to be purchased (the Company hereby irrevocably authorizing its
transfer agents to comply with all such requisitions) and (B) if the Company
elects pursuant to Section 5.5 not to issue certificates representing fractional
shares, requisition from the depository selected by the Company depository
receipts representing the fractional shares to be purchased or requisition from
the Company the amount of cash to be paid in lieu of fractional shares in
accordance with Section 5.5 and (ii) after receipt of such certificates,
depository receipts and/or cash, deliver the same to or upon the order of the
registered holder of such 


                                      -6-
<PAGE>   8
Rights Certificate, registered (in the case of certificates or depository
receipts) in such name or names as may be designated by such holder.


         (f) In case the holder of any Rights shall exercise less than all the
Rights evidenced by such holder's Rights Certificate, a new Rights Certificate
evidencing the Rights remaining unexercised will be issued by the Rights Agent
to such holder or to such holder's duly authorized assigns.


         (g) The Company covenants and agrees that it will (i) take all such
action as may be necessary to ensure that all shares delivered upon exercise of
Rights shall, at the time of delivery of the certificates for such shares
(subject to payment of the Exercise Price), be duly and validly authorized,
executed, issued and delivered and fully paid and nonassessable; (ii) take all
such action as may be necessary to comply with any applicable requirements of
the Securities Act of 1933 or the Securities Exchange Act of 1934, and the rules
and regulations thereunder, and any other applicable law, rule or regulation, in
connection with the issuance of any shares upon exercise of Rights; and (iii)
pay when due and payable any and all federal and state transfer taxes and
charges which may be payable in respect of the original issuance or delivery of
the Rights Certificates or of any shares issued upon the exercise of Rights,
provided that the Company shall not be required to pay any transfer tax or
charge which may be payable in respect of any transfer involved in the transfer
or delivery of Rights Certificates or the issuance or delivery of certificates
for shares in a name other than that of the holder of the Rights being
transferred or exercised.


         2.4 Adjustments to Exercise Price; Number of Rights. (a) In the event
the Company shall at any time after the Record Time and prior to the Separation
Time (i) declare or pay a dividend on Common Stock payable in Common Stock, (ii)
subdivide the outstanding Common Stock or (iii) combine the outstanding Common
Stock into a smaller number of shares of Common Stock, (x) the Exercise Price in
effect after such adjustment will be equal to the Exercise Price in effect
immediately prior to such adjustment divided by the number of shares of Common
Stock (the "Expansion Factor") that a holder of one share of Common Stock
immediately prior to such dividend, subdivision or combination would hold
thereafter as a result thereof and (y) each Right held prior to such adjustment
will become that number of Rights equal to the Expansion Factor, and the
adjusted number of Rights will be deemed to be distributed among the shares of
Common Stock with respect to which the original Rights were associated (if they
remain outstanding) and the shares issued in respect of such dividend,
subdivision or combination, so that each such share of Common Stock will have
exactly one Right associated with it. Each adjustment made pursuant to this
paragraph shall be made as of the payment or effective date for the applicable
dividend, subdivision or combination.


         In the event the Company shall at any time after the Record Time and
prior to the Separation Time issue any shares of Common Stock otherwise than in
a transaction referred to in the preceding paragraph, each such share of Common
Stock so issued shall automatically have one new Right associated with it, which
Right shall be evidenced by the certificate representing such share. To the
extent provided in Section 5.3, Rights shall be issued by the Company in respect
of shares of Common Stock that are issued or sold by the Company after the
Separation Time.


         (b) In the event the Company shall at any time after the Record Time
and prior to the Separation Time issue or distribute any securities or assets in
respect of, in lieu of or in exchange for Common Stock (other than pursuant to a
regular periodic cash dividend or a dividend paid solely in Common Stock)
whether by dividend, in a reclassification or recapitalization (including any
such transaction involving a merger, consolidation or share exchange), or
otherwise, the Company shall make such adjustments, if any, in the Exercise
Price, number of Rights and/or securities or other property 


                                      -7-
<PAGE>   9
purchasable upon exercise of Rights as the Board of Directors of the Company, in
its sole discretion, may deem to be appropriate under the circumstances in order
to adequately protect the interests of the holders of Rights generally, and the
Company and the Rights Agent shall amend this Agreement as necessary to provide
for such adjustments.


         (c) Each adjustment to the Exercise Price made pursuant to this Section
2.4 shall be calculated to the nearest cent. Whenever an adjustment to the
Exercise Price is made pursuant to this Section 2.4, the Company shall (i)
promptly prepare a certificate setting forth such adjustment and a brief
statement of the facts accounting for such adjustment and (ii) promptly file
with the Rights Agent and with each transfer agent for the Common Stock a copy
of such certificate. The Rights Agent shall be fully protected in relying on any
such certificate and on any adjustment therein and shall not be deemed to have
knowledge of any such adjustment unless and until it shall have received such a
certificate.


         Rights certificates shall represent the securities purchasable under
the terms of this Agreement, including any adjustment or change in the
securities purchasable upon exercise of the Rights, even though such
certificates may continue to express the securities purchasable at the time of
issuance of the initial Rights Certificates.


         2.5 Date on Which Exercise is Effective. Each person in whose name any
certificate for shares is issued upon the exercise of Rights shall for all
purposes be deemed to have become the holder of record of the shares represented
thereby on the date upon which the Rights Certificate evidencing such Rights was
duly surrendered and payment of the Exercise Price for such Rights (and any
applicable taxes and other governmental charges payable by the exercising holder
hereunder) was made; provided, however, that if the date of such surrender and
payment is a date upon which the stock transfer books of the Company are closed,
such person shall be deemed to have become the record holder of such shares on,
and such certificate shall be dated, the next succeeding Business Day on which
the stock transfer books of the Company are open.


         2.6 Execution, Authentication, Delivery and Dating of Rights
Certificates. (a) The Rights Certificates shall be executed on behalf of the
Company by its Chairman of the Board, President or one of its Vice Presidents,
under its corporate seal reproduced thereon attested by its Secretary or one of
its Assistant Secretaries. The signature of any of these officers on the Rights
Certificates may be manual or facsimile.


         Rights Certificates bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the countersignature and delivery of such Rights
Certificates.


         Promptly after the Separation Time, the Company will notify the Rights
Agent of such Separation Time and will deliver Rights Certificates executed by
the Company to the Rights Agent for countersignature, and, subject to Section
3.1(b), the Rights Agent shall manually countersign and deliver such Rights
Certificates to the holders of the Rights pursuant to Section 2.3(c) hereof. No
Rights Certificate shall be valid for any purpose unless manually countersigned
by the Rights Agent.


         (b) Each Rights Certificate shall be dated the date of countersignature
thereof.


                                      -8-
<PAGE>   10
         2.7 Registration, Registration of Transfer and Exchange. (a) After the
Separation Time, the Company will cause to be kept a register (the "Rights
Register") in which, subject to such reasonable regulations as it may prescribe,
the Company will provide for the registration and transfer of Rights. The Rights
Agent is hereby appointed "Rights Registrar" for the purpose of maintaining the
Rights Register for the Company and registering Rights and transfers of Rights
after the Separation Time as herein provided. In the event that the Rights Agent
shall cease to be the Rights Registrar, the Rights Agent will have the right to
examine the Rights Register at all reasonable times after the Separation Time.


         After the Separation Time and prior to the Expiration Time, upon
surrender for registration of transfer or exchange of any Rights Certificate,
and subject to the provisions of Section 2.7(c) and (d), the Company will
execute and the Rights Agent will countersign and deliver, in the name of the
holder or the designated transferee or transferees, as required pursuant to the
holder's instructions, one or more new Rights Certificates evidencing the same
aggregate number of Rights as did the Rights Certificate so surrendered.


         (b) Except as otherwise provided in Section 3.1(b), all Rights issued
upon any registration of transfer or exchange of Rights Certificates shall be
the valid obligations of the Company, and such Rights shall be entitled to the
same benefits under this Agreement as the Rights surrendered upon such
registration of transfer or exchange.


         (c) Every Rights Certificate surrendered for registration of transfer
or exchange shall be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company or the Rights Agent, as the case
may be, duly executed by the holder thereof or such holder's attorney duly
authorized in writing. As a condition to the issuance of any new Rights
Certificate under this Section 2.7, the Company may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto.


         (d) The Company shall not be required to register the transfer or
exchange of any Rights after such Rights have become void under Section 3.1(b),
been exchanged under Section 3.1(c) or been terminated under Section 5.1.


         2.8 Mutilated, Destroyed, Lost and Stolen Rights Certificates. (a) If
any mutilated Rights Certificate is surrendered to the Rights Agent prior to the
Expiration Time, then, subject to Sections 3.1(b), 3.1(c) and 5.1, the Company
shall execute and the Rights Agent shall countersign and deliver in exchange
therefor a new Rights Certificate evidencing the same number of Rights as did
the Rights Certificate so surrendered.


         (b) If there shall be delivered to the Company and the Rights Agent
prior to the Expiration Time (i) evidence to their satisfaction of the
destruction, loss or theft of any Rights Certificate and (ii) such security or
indemnity as may be required by them to save each of them and any of their
agents harmless, then, subject to Sections 3.1(b), 3.1(c) and 5.1 and in the
absence of notice to the Company or the Rights Agent that such Rights
Certificate has been acquired by a bona fide purchaser, the Company shall
execute and upon its request the Rights Agent shall countersign and deliver, in
lieu of any such destroyed, lost or stolen Rights Certificate, a new Rights
Certificate evidencing the same number of Rights as did the Rights Certificate
so destroyed, lost or stolen.


                                      -9-
<PAGE>   11
         (c) As a condition to the issuance of any new Rights Certificate under
this Section 2.8, the Company may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Rights
Agent) connected therewith.


         (d) Every new Rights Certificate issued pursuant to this Section 2.8 in
lieu of any destroyed, lost or stolen Rights Certificate shall evidence an
original additional contractual obligation of the Company, whether or not the
destroyed, lost or stolen Rights Certificate shall be at any time enforceable by
anyone, and, subject to Section 3.1(b), shall be entitled to all the benefits of
this Agreement equally and proportionately with any and all other Rights duly
issued hereunder.


         2.9 Persons Deemed Owners. Prior to due presentment of a Rights
Certificate (or, prior to the Separation Time, the associated Common Stock
certificate) for registration of transfer, the Company, the Rights Agent and any
agent of the Company or the Rights Agent may deem and treat the person in whose
name such Rights Certificate (or, prior to the Separation Time, such Common
Stock certificate) is registered as the absolute owner thereof and of the Rights
evidenced thereby for all purposes whatsoever, and neither the Company nor the
Rights Agent shall be affected by any notice to the contrary. As used in this
Agreement, unless the context otherwise requires, the term "holder" of any
Rights shall mean the registered holder of such Rights (or, prior to the
Separation Time, the associated shares of Common Stock).


         2.10 Delivery and Cancellation of Certificates. All Rights Certificates
surrendered upon exercise or for registration of transfer or exchange shall, if
surrendered to any person other than the Rights Agent, be delivered to the
Rights Agent and, in any case, shall be promptly canceled by the Rights Agent.
The Company may at any time deliver to the Rights Agent for cancellation any
Rights Certificates previously countersigned and delivered hereunder which the
Company may have acquired in any manner whatsoever, and all Rights Certificates
so delivered shall be promptly canceled by the Rights Agent. No Rights
Certificates shall be countersigned in lieu of or in exchange for any Rights
Certificates canceled as provided in this Section 2.10, except as expressly
permitted by this Agreement. The Rights Agent shall return all canceled Rights
Certificates to the Company.


         2.11 Agreement of Rights Holders. Every holder of Rights by accepting
the same consents and agrees with the Company and the Rights Agent and with
every other holder of Rights that:


         (a) prior to the Separation Time, each Right will be transferable only
together with, and will be transferred by a transfer of, the associated share of
Common Stock;


         (b) after the Separation Time, the Rights Certificates will be
transferable only on the Rights Register as provided herein;


         (c) prior to due presentment of a Rights Certificate (or, prior to the
Separation Time, the associated Common Stock certificate) for registration of
transfer, the Company, the Rights Agent and any agent of the Company or the
Rights Agent may deem and treat the person in whose name the Rights Certificate
(or, prior to the Separation Time, the associated Common Stock certificate) is
registered as the absolute owner thereof and of the Rights evidenced thereby for
all purposes whatsoever, and neither the Company nor the Rights Agent shall be
affected by any notice to the contrary;


                                      -10-
<PAGE>   12
         (d) Rights beneficially owned by certain Persons will, under the
circumstances set forth in Section 3.1(b), become void; and


         (e) this Agreement may be supplemented or amended from time to time
pursuant to Section 2.4(b) or 5.4 hereof.


                                   ARTICLE III

                          ADJUSTMENTS TO THE RIGHTS IN
                        THE EVENT OF CERTAIN TRANSACTIONS

         3.1 Flip-in. (a) In the event that prior to the Expiration Time a
Flip-In Date shall occur, except as provided in this Section 3.1, each Right
shall constitute the right to purchase from the Company, upon exercise thereof
in accordance with the terms hereof (but subject to Section 5.10), that number
of shares of Common Stock having an aggregate Market Price on the Stock
Acquisition Date equal to twice the Exercise Price for an amount in cash equal
to the Exercise Price (such right to be appropriately adjusted in order to
protect the interests of the holders of Rights generally in the event that on or
after such Stock Acquisition Date an event of a type analogous to any of the
events described in Section 2.4(a) or (b) shall have occurred with respect to
the Common Stock).


         (b) Notwithstanding the foregoing, any Rights that are or were
Beneficially Owned on or after the Stock Acquisition Date by an Acquiring Person
or an Affiliate or Associate thereof or by any transferee, direct or indirect,
of any of the foregoing shall become void and any holder of such Rights
(including transferees) shall thereafter have no right to exercise or transfer
such Rights under any provision of this Agreement. If any Rights Certificate is
presented for assignment or exercise and the Person presenting the same will not
complete the certification set forth at the end of the form of assignment or
notice of election to exercise and provide such additional evidence of the
identity of the Beneficial Owner and its Affiliates and Associates (or former
Beneficial owners and their Affiliates and Associates) as the Company shall
reasonably request, then the Company shall be entitled conclusively to deem the
Beneficial owner thereof to be an Acquiring Person or an Affiliate or Associate
thereof or a transferee of any of the foregoing and accordingly will deem the
Rights evidenced thereby to be void and not transferable or exercisable.


         (c) The Board of Directors of the Company may, at its option, at any
time after a Flip-In Date and prior to the time that an Acquiring Person becomes
the Beneficial owner of more than 50% of the outstanding shares of Common stock,
elect to exchange all (but not less than all) the then outstanding Rights (which
shall not include Rights that have become void pursuant to the provisions of
Section 3.1(b)) for shares of Common Stock at an exchange ratio of one share of
Common Stock per Right, appropriately adjusted in order to protect the interests
of holders of Rights generally in the event that after the Separation Time an
event of a type analogous to any of the events described in Section 2.4(a) or
(b) shall have occurred with respect to the Common Stock (such exchange ratio,
as adjusted from time to time, being hereinafter referred to as the "Exchange
Ratio").


         Immediately upon the action of the Board of Directors of the Company
electing to exchange the Rights, without any further action and without any
notice, the right to exercise the Rights will terminate and each Right (other
than Rights that have become void pursuant to Section 3.1(b)) will thereafter
represent only the right to receive a number of shares of Common Stock equal to
the Exchange Ratio. Promptly after the action of the Board of Directors electing
to exchange the Rights, the Company shall give notice thereof (specifying the
steps to be taken to receive shares of Common Stock in exchange for


                                      -11-
<PAGE>   13
Rights) to the Rights Agent and the holders of the Rights (other than Rights
that have become void pursuant to Section 3.1(b)) outstanding immediately prior
thereto by mailing such notice in accordance with Section 5.9.


         Each Person in whose name any certificate for shares is issued upon the
exchange of Rights pursuant to this Section 3.1(c) or Section 3.1(d) shall for
all purposes be deemed to have become the holder of record of the shares
represented thereby on, and such certificate shall be dated, the date upon which
the Rights Certificate evidencing such Rights was duly surrendered and payment
of any applicable taxes and other governmental charges payable by the holder was
made; provided, however, that if the date of such surrender and payment is a
date upon which the stock transfer books of the Company are closed, such Person
shall be deemed to have become the record holder of such shares on, and such
Certificate shall be dated, the next succeeding Business Day on which the stock
transfer books of the Company are open.


         (d) Whenever the Company shall become obligated under Section 3.1(a) or
(c) to issue shares of Common Stock upon exercise of or in exchange for Rights,
the Company, at its option, may substitute therefor shares of Preferred Stock,
at a ratio of one one-hundredth (1/100th) of a share of Preferred Stock for each
share of Common Stock so issuable.


         (e) In the event that there shall not be sufficient treasury shares or
authorized but unissued shares of Common Stock or Preferred Stock of the Company
to permit the exercise or exchange in full of the Rights in accordance with
Section 3.1(a) or (c), the Company shall either (i) call a meeting of
shareholders seeking approval to cause sufficient additional shares to be
authorized (provided that if such approval is not obtained the Company will take
the action specified in clause (ii) of this sentence) or (ii) take such action
as shall be necessary to ensure and provide, to the extent permitted by
applicable law and any agreements or instruments in effect on the Stock
Acquisition Date to which it is a party, that each Right shall thereafter
constitute the right to receive, (x) at the Company's option, either (A) in
return for the Exercise Price, debt or equity securities or other assets (or a
combination thereof) having a fair value equal to twice the Exercise Price, or
(B) without payment of consideration (except as otherwise required by applicable
law), debt or equity securities or other assets (or a combination thereof)
having a fair value equal to the Exercise Price, or (y) if the Board of
Directors of the Company elects to exchange the Rights in accordance with
Section 3.1(c), debt or equity securities or other assets (or a combination
thereof) having a fair value equal to the product of the Market Price of a share
of Common Stock on the Flip-In Date times the Exchange Ratio in effect on the
Flip-In Date, where in any case set forth in (x) or (y) above the fair value of
such debt or equity securities or other assets shall be as determined in good
faith by the Board of Directors of the Company, after consultation with a
nationally recognized investment banking firm.


         3.2 Flip-over. (a) Prior to the Expiration Time, the Company shall not
enter into any agreement with respect to, consummate or permit to occur any
Flip-Over Transaction or Event unless and until it shall have entered into a
supplemental agreement with the Flip-Over Entity, for the benefit of the holders
of the Rights, providing that, upon consummation or occurrence of the Flip-Over
Transaction or Event (i) each Right shall thereafter constitute the right to
purchase from the Flip-Over Entity, upon exercise thereof in accordance with the
terms hereof, that number of shares of Flip-Over Stock of the Flip-Over Entity
having an aggregate Market Price on the date of consummation or occurrence of
such Flip-Over Transaction or Event equal to twice the Exercise Price for an
amount in cash equal to the Exercise Price (such right to be appropriately
adjusted in order to protect the interests of the holders of Rights generally in
the event that after such date of consummation or occurrence an event of a type
analogous to any of the events described in Section 2.4(a) or (b) shall have
occurred with respect to the Flip-Over Stock) and (ii) the Flip-Over Entity
shall thereafter be liable for, and shall assume, by virtue of such Flip-


                                      -12-
<PAGE>   14
Over Transaction or Event and such supplemental agreement, all the obligations
and duties of the Company pursuant to this Agreement. The provisions of this
Section 3.2 shall apply to successive Flip-Over Transactions or Events.


         (b) Prior to the Expiration Time, unless the Rights will be terminated
pursuant to Section 5.1 hereof in connection therewith, the Company shall not
enter into any agreement with respect to, consummate or permit to occur any
Flip-Over Transaction or Event if at the time thereof there are any rights,
warrants or securities outstanding or any other arrangements, agreements or
instruments that would eliminate or otherwise diminish in any material respect
the benefits intended to be afforded by this Rights Agreement to the holders of
Rights upon consummation of such transaction.


                                   ARTICLE IV

                                THE RIGHTS AGENT

         4.1 General. (a) The Company hereby appoints the Rights Agent to act as
agent for the Company in accordance with the terms and conditions hereof, and
the Rights Agent hereby accepts such appointment. The Company agrees to pay to
the Rights Agent reasonable compensation for all services rendered by it
hereunder and, from time to time, on demand of the Rights Agent, its reasonable
expenses and counsel fees and other disbursements incurred in the administration
and execution of this Agreement and the exercise and performance of its duties
hereunder. The Company also agrees to indemnify the Rights Agent, its directors,
officers, employees and agentsfor, and to hold each of them harmless against,
any loss, liability, or expense, incurred without gross negligence, bad faith or
willful misconduct on the part of the Rights Agent or such indemnified party,
for anything done or omitted to be done by the Rights Agent in connection with
the acceptance and administration of this Agreement or the exercise or
performance of its duties hereunder, including the costs and expenses of
defending against any claim of liability. The indemnity provided in this Section
4.1(a) shall survive the expiration of the Rights and the termination of this
Agreement.


         (b) The Rights Agent shall be protected and shall incur no liability
for or in respect of any action taken, suffered or omitted by it in connection
with its administration of this Agreement or the exercise or performance of its
duties hereunder in reliance upon any certificate for securities purchasable
upon exercise of Rights, Rights Certificate, certificate for other securities of
the Company, instrument of assignment or transfer, power of attorney,
endorsement, affidavit, letter, notice, direction, consent, certificate,
statement, or other paper or document believed by it to be genuine and to be
signed, executed and, where necessary, verified or acknowledged, by the proper
person or persons.


         4.2 Merger or Consolidation or Change of Name of Rights Agent. (a) Any
corporation into which the Rights Agent or any successor Rights Agent may be
merged or with which it may be consolidated, or any corporation resulting from
any merger or consolidation to which the Rights Agent or any successor Rights
Agent is a party, or any corporation succeeding to the shareholder services
business of the Rights Agent or any successor Rights Agent, will be the
successor to the Rights Agent under this Agreement without the execution or
filing of any paper or any further act on the part of any of the parties hereto,
provided that such corporation would be eligible for appointment as a successor
Rights Agent under the provisions of Section 4.4 hereof. In case at the time
such successor Rights Agent succeeds to the agency created by this Agreement any
of the Rights Certificates have been countersigned but not delivered, any such
successor Rights Agent may adopt the countersignature of the predecessor Rights
Agent and deliver such Rights Certificates so countersigned; and in case at that
time any of the Rights Certificates have not been countersigned, any successor
Rights Agent may countersign such Rights Certificates either in the name of the
predecessor Rights Agent or in the name of the successor Rights 


                                      -13-

Agent; and in all such cases such Rights Certificates will have the full force
provided in the Rights Certificates and in this Agreement.


         (b) In case at any time the name of the Rights Agent is changed and at
such time any of the Rights Certificates shall have been countersigned but not
delivered, the Rights Agent may adopt the countersignature under its prior name
and deliver Rights Certificates so countersigned; and in case at that time any
of the Rights Certificates shall not have been countersigned, the Rights Agent
may countersign such Rights Certificates either in its prior name or in its
changed name; and in all such cases such Rights Certificates shall have the full
force provided in the Rights Certificates and in this Agreement.


         4.3 Duties of Rights Agent. The Rights Agent undertakes the duties and
obligations imposed by this Agreement upon the following terms and conditions,
by all of which the Company and the holders of Rights Certificates, by their
acceptance thereof, shall be bound:


         (a) The Rights Agent may consult with legal counsel (who may be legal
counsel for the Company), and the advice or opinion of such counsel will be full
and complete authorization and protection to the Rights Agent as to any action
taken or omitted by it in good faith and in accordance with such advice or
opinion.


         (b) Whenever in the performance of its duties under this Agreement the
Rights Agent deems it necessary or desirable that any fact or matter be proved
or established by the Company prior to taking or suffering any action hereunder,
such fact or matter (unless other evidence in respect thereof be herein
specifically prescribed) may be deemed to be conclusively proved and established
by a certificate signed by a person believed by the Rights Agent to be the
Chairman of the Board, the President or any Vice President and by the Treasurer
or any Assistant Treasurer or the Secretary or any Assistant Secretary of the
Company and delivered to the Rights Agent; and such certificate will be full
authorization to the Rights Agent for any action taken or suffered in good faith
by it under the provisions of this Agreement in reliance upon such certificate.


         (c) The Rights Agent will be liable hereunder only for its own gross
negligence, bad faith or willful misconduct.


         (d) The Rights Agent will not be liable for or by reason of any of the
statements of fact or recitals contained in this Agreement or in the
certificates for securities purchasable upon exercise of Rights or the Rights
Certificates (except its countersignature thereof) or be required to verify the
same, but all such statements and recitals are and will be deemed to have been
made by the Company only.


         (e) The Rights Agent will not be under any responsibility in respect of
the validity of any provision of this Agreement or the execution and delivery
hereof (except the due authorization, execution and delivery hereof by the
Rights Agent) or in respect of the validity or execution of any certificate for
securities purchasable upon exercise of Rights or Rights Certificate (except its
countersignature thereof); nor will it be responsible for any breach by the
Company of any covenant or condition contained in this Agreement or in any
Rights Certificate; nor will it be responsible for any change in the
exercisability of the Rights (including the Rights becoming void pursuant to
Section 3.1(b) hereof) or any adjustment required under any provision of this
Agreement or responsible for the manner, method or amount of any such adjustment
or the ascertaining of the existence of facts that would require any such
adjustment (except with respect to the exercise of Rights after receipt of the
certificate contemplated by Section 2.4 


                                      -14-
<PAGE>   16
describing any such adjustment); nor will it by any act hereunder be deemed to
make any representation or warranty as to the authorization or reservation of
any securities purchasable upon exercise of Rights or any Rights or as to
whether any securities purchasable upon exercise of Rights will, when issued, be
duly and validly authorized, executed, issued and delivered and fully paid and
nonassessable.


         (f) The Company agrees that it will perform, execute, acknowledge and
deliver or cause to be performed, executed, acknowledged and delivered all such
further and other acts, instruments and assurances as may reasonably be required
by the Rights Agent for the carrying out or performing by the Rights Agent of
the provisions of this Agreement.


         (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
person believed by the Rights Agent to be the Chairman of the Board, the
President or any Vice President or the Secretary or any Assistant Secretary or
the Treasurer or any Assistant Treasurer of the Company, and to apply to such
persons for advice or instructions in connection with its duties, and it shall
not be liable for any action taken or suffered by it in good faith in accordance
with instructions of any such person, or for any delay in acting while awaiting
instructions. Any application by the Rights Agent for written instructions from
the Company may, at the option of the Rights Agent, set forth in writing any
action proposed to be taken or omitted by the Rights Agent under this Agreement
and the date on or after which such action shall be taken or such omission shall
be effective. The Rights Agent shall not be liable for any action taken by, or
omission of, the Rights Agent in accordance with a proposal included in any such
application on or after the date specified in such application (which date shall
not be less than five Business Days after the date any officer of the Company
actually receives such application, unless any such officer shall have consented
in writing to an earlier date) unless, prior to taking any such action (or the
effective date in the case of an omission), the Rights Agent shall have received
written instructions in response to such application specifying the action to be
taken or omitted.


         (h) The Rights Agent and any shareholder, director, officer or employee
of the Rights Agent may buy, sell or deal in Common Stock, Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to the
Company or otherwise act as fully and freely as though it were not Rights Agent
under this Agreement. Nothing herein shall preclude the Rights Agent from acting
in any other capacity for the Company or for any other legal entity.


         (i) The Rights Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys or agents, and the Rights Agent will not be answerable or
accountable for any act, default, neglect or misconduct of any such attorneys or
agents or for any loss to the Company resulting from any such act, default,
neglect or misconduct, provided the Rights Agent was not grossly negligent in
the selection and continued employment thereof.


         (j) The Rights Agent undertakes only the express duties and obligations
imposed on it by this Agreement and no implied duties or obligations shall be
read into this Agreement against the Rights Agent.


         (k) Anything in this Agreement to the contrary notwithstanding, in no
event shall the Rights Agent be liable for special, indirect or consequential
loss or damage of any kind whatsoever (including but not limited to lost
profits).


                                      -15-
<PAGE>   17
         (l) No provision of this Agreement shall require the Rights Agent to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or in the exercise of its rights if
there shall be reasonable grounds for believing that repayment of such funds or
adequate indemnification against such risk or liability is not reasonably
assured to it.


         4.4 Change of Rights Agent. The Rights Agent may resign and be
discharged from its duties under this Agreement upon 90 days notice (or such
lesser notice as is acceptable to the Company) in writing mailed to the Company
and to each transfer agent of Common Stock by registered or certified mail, and
to the holders of the Rights in accordance with Section 5.9. The Company may
remove the Rights Agent upon 30 days notice in writing, mailed to the Rights
Agent and to each transfer agent of the Common Stock by registered or certified
mail, and to the holders of the Rights in accordance with Section 5.9. If the
Rights Agent should resign or be removed or otherwise become incapable of
acting, the Company will appoint a successor to the Rights Agent. If the Company
fails to make such appointment within a period of 30 days after such removal or
after it has been notified in writing of such resignation or incapacity by the
resigning or incapacitated Rights Agent or by the holder of any Rights (which
holder shall, with such notice, submit such holder's Rights Certificate for
inspection by the Company), then the holder of any Rights may apply to any court
of competent jurisdiction for the appointment of a new Rights Agent. Any
successor Rights Agent, whether appointed by the Company or by such a court,
shall be (a) a corporation organized and doing business under the laws of the
United States or of the State of Georgia or any other State of the United
States, in good standing, which is authorized under such laws to exercise the
powers of the Rights Agent contemplated by this Agreement and is subject to
supervision or examination by federal or state authority and which has at the
time of its appointment as Rights Agent a combined capital and surplus of at
least $50,000,000 or (b) an affiliate of a corporation described in the
immediately preceding clause (a). After appointment, the successor Rights Agent
will be vested with the same powers, rights, duties and responsibilities as if
it had been originally named as Rights Agent without further act or deed; but
the predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company will file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Common Stock, and mail a notice thereof in writing to the holders of the
Rights. Failure to give any notice provided for in this Section 4.4, however, or
any defect therein, shall not affect the legality or validity of the resignation
or removal of the Rights Agent or the appointment of the successor Rights Agent,
as the case may be.

                                  MISCELLANEOUS

         5.1 Termination. (a) The Board of Directors of the Company may, at its
option, at any time prior to the close of business on the Flip-In Date, elect to
terminate the Rights without any payment to any holder thereof.


         (b) Immediately upon the action of the Board of Directors of the
Company electing to terminate the Rights (or, if the resolution of the Board of
Directors electing to terminate the Rights states that the termination will not
be effective until the occurrence of a specified future time or event, upon the
occurrence of such future time or event), without any further action and without
any notice, the right to exercise the Rights will terminate and each Right will
thereafter be null and void.


                                      -16-
<PAGE>   18
         5.2 Expiration. The Rights and this Agreement shall expire at the
Expiration Time and no Person shall have any rights pursuant to this Agreement
or any Right after the Expiration Time, except, if the Rights are exchanged, as
provided in Section 3.1 hereof.


         5.3 Issuance of New Rights Certificate. Notwithstanding any of the
provisions of this Agreement or of the Rights to the contrary, the Company may,
at its option, issue new Rights Certificates evidencing Rights in such form as
may be approved by its Board of Directors to reflect any adjustment or change in
the number or kind or class of shares of stock purchasable upon exercise of
Rights made in accordance with the provisions of this Agreement. In addition, in
connection with the issuance or sale of shares of Common Stock by the Company
following the Separation Time and prior to the Expiration Time pursuant to the
terms of securities convertible or redeemable into shares of Common Stock or to
options, in each case issued or granted prior to, and outstanding at, the
Separation Time, the Company shall issue to the holders of such shares of Common
Stock, Rights Certificates representing the appropriate number of Rights in
connection with the issuance or sale of such shares of Common Stock; provided,
however, in each case, (i) no such Rights Certificate shall be issued, if, and
to the extent that, the Company shall be advised by counsel that such issuance
would create a significant risk of material adverse tax consequences to the
Company or to the Person to whom such Rights Certificates would be issued, (ii)
no such Rights Certificates shall be issued if, and to the extent that,
appropriate adjustment shall have otherwise been made in lieu of the issuance
thereof, and (iii) the Company shall have no obligation to distribute Rights
Certificates to any Acquiring Person or Affiliate or Associate of an Acquiring
Person or any transferee of any of the foregoing.


         5.4 Supplements and Amendments. The Company and the Rights Agent may
from time to time supplement or amend this Agreement without the approval of any
holders of Rights (i) prior to the close of business on the Flip-In Date, in any
respect and (ii) after the close of business on the Flip-In Date, to make any
changes that the Company may deem necessary or desirable and which shall not
materially adversely affect the interests of the holders of Rights generally or
in order to cure any ambiguity or to correct or supplement any provision
contained herein which may be inconsistent with any other provisions herein or
otherwise defective. The Rights Agent will duly execute and deliver any
supplement or amendment hereto requested by the Company upon receipt of a
certificate from the Company that such supplement or amendment satisfies the
terms of the preceding sentence. Notwithstanding anything contained in this
Agreement to the contrary, no supplement or amendment that changes the rights
and duties of the Rights Agent under this Agreement shall be effective without
the consent of the Rights Agent.


         5.5 Fractional Shares. If the Company elects not to issue certificates
representing fractional shares upon exercise of Rights, the Company shall, in
lieu thereof, in the sole discretion of the Board of Directors, either (a)
evidence such fractional shares by depository receipts issued pursuant to an
appropriate agreement between the Company and a depository selected by it,
providing that each holder of a depository receipt shall have all of the rights,
privileges and preferences to which such holder would be entitled as a
beneficial owner of such fractional share, or (b) sell such shares on behalf of
the holders of Right and pay to the registered holder of such Rights the
appropriate fraction of price per share received upon such sale.


         5.6 Rights of Action. Subject to the terms of this Agreement (including
Section 3.1(b)), rights of action in respect of this Agreement, other than
rights of action vested solely in the Rights Agent, are vested in the respective
holders of the Rights; and any holder of any Rights, without the consent of the
Rights Agent or of the holder of any other Rights, may, on such holder's own
behalf and for such holder's own benefit and the benefit of other holders of
Rights, enforce, and may institute and maintain any suit, action or proceeding
against the Company to enforce, or otherwise act in respect of, such holder's
right to 


                                      -17-
<PAGE>   19
exercise such holder Rights in the manner provided in such holder's Rights
Certificate and in this Agreement. Without limiting the foregoing or any
remedies available to the holders of Rights, it is specifically acknowledged
that the holders of Rights would not have an adequate remedy at law for any
breach of this Agreement and will be entitled to specific performance of the
obligations under, and injunctive relief against actual or threatened violations
of, the obligations of any Person subject to this Agreement.


         5.7 Holder of Rights Not Deemed a Shareholder. No holder, as such, of
any Rights shall be entitled to vote, receive dividends or be deemed for any
purpose the holder of shares or any other securities which may at any time be
issuable on the exercise of such Rights, nor shall anything contained herein or
in any Rights Certificate be construed to confer upon the holder of any Rights,
as such, any of the rights of a shareholder of the Company or any right to vote
for the election of directors or upon any matter submitted to shareholders at
any meeting thereof, or to give or withhold consent to any corporate action, or
to receive notice of meetings or other actions affecting shareholders (except as
provided in Section 5.8 hereof), or to receive dividends or subscription rights,
or otherwise, until such Rights shall have been exercised or exchanged in
accordance with the provisions hereof.


         5.8 Notice of Proposed Actions. In case the Company shall propose after
the Separation Time and prior to the Expiration Time (i) to effect or permit
occurrence of any Flip-Over Transaction or Event or (ii) to effect the
liquidation, dissolution or winding up of the Company, then, in each such case,
the Company shall give to each holder of a Right, in accordance with Section 5.9
hereof, a notice of such proposed action, which shall specify the date on which
such Flip-Over Transaction or Event, liquidation, dissolution, or winding up is
to take place, and such notice shall be so given at least 20 Business Days prior
to the date of the taking of such proposed action.

         THE RIGHTS ARE SUBJECT TO TERMINATION OR MANDATORY EXCHANGE, AT THE
         OPTION OF THE COMPANY, ON THE TERMS SET FORTH IN THE RIGHTS AGREEMENT.
         RIGHTS BENEFICIALLY OWNED BY ACQUIRING PERSONS OR AFFILIATES OR

                             RENAL CARE GROUP, INC.

         This certifies that _______________________, or registered assigns, is
the registered holder of the number of Rights set forth above, each of which
entitles the registered holder thereof, subject to the terms, provisions and
conditions of the Shareholder Protection Rights Agreement, dated as of May 2,
1997 (as amended from time to time, the "Rights Agreement"), between Renal Care
Group, Inc., a Delaware corporation (the "Company"), and First Union National
Bank of North Carolina, as Rights Agent (the "Rights Agent," which term shall
include any successor Rights Agent under the Rights Agreement), to purchase from
the Company at any time after the Separation Time (as such term is defined in
the Rights Agreement) and prior to the close of business on May 2, 2007, one
one-hundredth (1/100th) of a fully paid share of Series A Junior Participating
Preferred Stock, par value $0.01 per share (the "Preferred Stock"), of the
Company (subject to adjustment as provided in the Rights Agreement) at the
Exercise Price referred to below, upon presentation and surrender of this Rights
Certificate with the Form of Election to Exercise duly executed at the principal
office of the Rights Agent. The Exercise Price shall initially be $____ per
Right and shall be subject to adjustment in certain events as provided in the
Rights Agreement.

         In certain circumstances described in the Rights Agreement, the Rights
evidenced hereby may entitle the registered holder thereof to purchase
securities of an entity other than the Company or securities or assets of the
Company other than Preferred Stock, all as provided in the Rights Agreement.

         This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities hereunder of the
Rights Agent, the Company and the holders of the Rights Certificates. Copies of
the Rights Agreement are on file at the principal office of the Company and are
available without cost upon written request.

         This Rights Certificate, with or without other Rights Certificates,
upon surrender at the office of the Rights Agent designated for such purpose,
may be exchanged for another Rights Certificate or Rights Certificates of like
tenor evidencing an aggregate number of Rights equal to the aggregate number of
Rights evidenced by the Rights Certificate or Rights Certificates surrendered.
If this Rights Certificate shall be exercised in part, the registered holder
shall be entitled to receive, upon surrender hereof, another Rights Certificate
or Rights Certificates for the number of whole Rights not exercised.

         Subject to the provisions of the Rights Agreement, each Right evidenced
by this Certificate may be (a) terminated by the Company under certain
circumstances, at its option, or (b) exchanged by the Company 
<PAGE>   24
under certain circumstances, at its option, for one share of Common Stock or one
one-hundredth (1/100th) of a share of Preferred Stock per Right (or, in certain
cases, other securities or assets of the Company), subject in each case to
adjustment in certain events as provided in the Rights Agreement.

                                       OF

                             RENAL CARE GROUP, INC.

                        Pursuant to Section 151 of the
                       Delaware General Corporation Law

                  Renal Care Group, Inc., a corporation organized under the laws
of the State of Delaware (the "Corporation"), hereby certifies that, pursuant to
the authority conferred upon the Board of Directors by the Certificate of
Incorporation, as amended, of the Corporation, the Board of Directors on May
2, 1997, adopted the following resolution creating a series of 400,000 shares
of Preferred Stock designated as Series A Junior Participating Preferred Stock:

         RESOLVED, that pursuant to the authority granted to and vested in the
Board of Directors of this Corporation (the "Board") in accordance with the
provisions of its Certificate of Incorporation, as amended, a series of
Preferred Stock of the Corporation be and it hereby is created, and that the
designation and amount thereof and the voting rights or powers, preferences and
relative, participating, optional and other special rights of the shares of such
series, and the qualifications, limitations or restrictions thereof are as
follows:


                  1. Series A Participating Preferred Stock. There is hereby
established a series of Preferred Stock, par value $0.01 per share, of the
Corporation, and the designation and certain terms, powers, preferences and
other rights of the shares of such series, and certain qualifications,
limitations and restrictions thereon, are hereby fixed as follows:

                           (i) The distinctive serial designation of this series
shall be "Series A Junior Participating Preferred Stock" (hereinafter called
"this Series"). Each share of this Series shall be identical in all with the
other shares of this Series except as to the dates from and after which
dividends thereon shall be cumulative.

                           (ii) The number of shares in this Series shall
initially be 400,000, which number may from time to time be increased or
decreased (but not below the number then outstanding) by the Board of Directors.
Shares of this Series purchased by the Corporation shall be canceled and shall
revert to authorized but unissued shares of Preferred Stock undesignated as to
series. Shares of this Series may be issued in fractional shares, which
fractional shares shall entitle the holder, in proportion to such holder's
fractional share, to all rights of a holder of a whole share of this Series.

                           (iii) The holders of full or fractional shares of
this Series shall be entitled to receive, when and as declared by the Board of
Directors, but only out of funds legally available therefor, dividends, (A) on
each date that dividends or other distributions payable in Common Stock of the
Corporation are payable on or in respect of Common Stock comprising part of the
Reference Package (as defined below), in an amount per whole share of this
Series equal to the aggregate amount of dividends or other distributions (other
than dividends or distributions payable in Common Stock of the Corporation) that
would be payable on such date to a holder of the Reference Package and (B) on
the last day of March, June,
<PAGE>   30
September and December in each year, in an amount per whole share of this Series
equal to the excess (if any) of $1.00 over the aggregate dividends paid per
whole share of this Series during the three-month period ending on such last
day. Each such dividend shall be paid to the holders of record of shares of this
Series on the date, not exceeding sixty days preceding such dividend or
distribution payment date, fixed for that purpose by the Board of Directors in
advance of payment of each particular dividend or distribution. Dividends on
each full and each fractional share of this Series shall be cumulative from the
date such full or fractional share is originally issued; provided that any such
full or fractional share originally issued after a dividend record date and on
or prior to the dividend payment date to which such record date relates shall
not be entitled to receive the dividend payable on such dividend payment date or
any amount in respect of the period from such original issuance to such dividend
payment date.

                  The term "Reference Package" shall initially mean 100 shares
of Common Stock, par value $0.01 per share ("Common Stock"), of the Corporation.
In the event the Corporation shall at any time (A) declare or pay a dividend on
any Common Stock payable in Common Stock, (B) subdivide any Common Stock or (C)
combine any Common Stock into a smaller number of shares, then and in each such
case the Reference Package after such event shall be the Common Stock that a
holder of the Reference Package immediately prior to such event would hold
thereafter as a result thereof.

                  Holders of shares of this Series shall not be entitled to any
dividends, whether payable in cash, property or stock, in excess of full
cumulative dividends, as herein provided on this Series.

                  So long as any shares of this Series are outstanding, no
dividend (other than a dividend in Common Stock or in any other stock ranking
junior to this Series as to dividends and upon liquidation) shall be declared or
paid or set aside for payment or other distribution declared or made upon the
Common Stock or upon any other stock ranking junior to this Series as to
dividends or upon liquidation, nor shall any Common Stock nor any other stock of
the Corporation ranking junior to or on a parity with this Series as to
dividends or upon liquidation be redeemed, purchased or otherwise acquired for
any consideration (or any moneys be paid to or made available for a sinking fund
for the redemption of any shares of any such stock) by the Corporation (except
by conversion into or exchange for stock of the Corporation ranking junior to
this Series as to dividends and upon liquidation), unless, in each case, the
full cumulative dividends (including the dividend to be due upon payment of such
dividend, distribution, redemption, purchase or other acquisition) on all
outstanding shares of this Series shall have been, or shall contemporaneously
be, paid.

                  (iv) In the event of any merger, consolidation,
reclassification or other transaction in which the shares of Common Stock are
exchanged for or changed into other stock or securities, cash and/or any other
property, then in any such case the shares of this Series shall at the same time
be similarly exchanged or changed in an amount per whole share equal to the
aggregate amount of stock, securities, cash and/or any other property (payable
in kind), as the case may be, that a holder of the Reference Package would be
entitled to receive as a result of such transaction.

                  (v) In the event of any liquidation, dissolution or winding up
of the affairs of the Corporation, whether voluntary or involuntary, the holders
of full and fractional shares of this Series shall be entitled, before any
distribution or payment is made on any date to the holders of the Common Stock
or any other stock of the Corporation ranking junior to this Series upon
liquidation, to be paid in full an amount per whole share of this Series equal
to-the greater of (A) $1.00 or (B) the aggregate amount distributed or to be
distributed prior to such date in connection with such liquidation, dissolution
or winding up to a holder of the Reference Package (such greater amount being
hereinafter referred to as the "Liquidation Preference"), together with accrued
dividends to such distribution or payment date, whether or not earned or
declared. If such payment shall have been made in full to all holders of shares
of this Series, the holders of shares of this Series as such shall have no right
or claim to any of the remaining assets of the Corporation.

                  In the event the assets of the Corporation available for
distribution to the holders of shares of this Series upon any liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
shall be insufficient to pay in full all amounts to which such holders are
entitled pursuant to the first paragraph of this Section (v), no such
distribution shall be made on account of any shares of any other class or series
of Preferred Stock ranking on a parity with the shares of this Series upon such
liquidation, dissolution or winding up unless proportionate distributive amounts
shall be paid on account of the shares of this Series, ratably in proportion to
the full distributable, amounts for which holders of all such parity shares are
respectively entitled upon such liquidation, dissolution or winding up.

                  Upon the liquidation, dissolution or winding up of the
Corporation, the holders of shares of this Series then outstanding shall be
entitled to be paid out of assets of the Corporation available for distribution
to its stockholders all amounts to which such holders are entitled pursuant to
the first paragraph of this Section (v) before any payment shall be made to the
holders of Common Stock or any other stock of the Corporation ranking junior
upon liquidation to this Series.

                  For the purposes of this Section (v), the consolidation or
merger of, or binding share exchange by, the Corporation with any other
corporation shall not be deemed to constitute a liquidation, dissolution or
winding up of the corporation.

                  (vi)  The shares of this Series shall not be redeemable.

                  (vii) In addition to any other vote or consent of
stockholders required by law or by the Certificate of Incorporation, as
amended, of the Corporation, each whole share of this Series shall, on any
matter, vote as a class with any other capital stock comprising part of the
Reference Package and voting on such matter and shall have the number of votes
thereon that a holder of the Reference Package would have.

                
                  IN WITNESS WHEREOF, Renal Care Group, Inc. has caused this
Certificate of Designation to be executed as of May ____, 1997.

RENAL CARE GROUP, INC. ADOPTS SHAREHOLDER PROTECTION RIGHTS AGREEMENT

         Nashville, Tennessee. May 2, 1997. Renal Care Group, Inc. today
announced that its Board of Directors has adopted a shareholder protection
rights agreement designed to enhance the ability of all shareholders to realize
the long-term value of their investment in the Company.

         The rights plan provides that one preferred stock purchase right will
be distributed as a dividend on each outstanding share of common stock of the
Company held of record as of the close of business on June 2, 1997.

         Sam A. Brooks, Jr., President and Chief Executive Officer of the
Company, said: "The rights plan does not prevent a takeover, but it is
designed to protect shareholders' interests by encouraging anyone seeking
control of the Company to negotiate with the Board of Directors." A spokesman
also noted that such plans have been adopted by a significant number of public
corporations in recent years. The Board's action came after consulting with
legal and other advisors.

         Each right will entitle holders of a share of common stock to purchase
one one-hundredth of a new series of junior participating preferred stock of the
Company at an exercise price of $140. Each such fractional share of preferred
stock is equivalent in voting power to one share of Company common stock and
would be paid dividends equal to the dividends paid on each share of common
stock. The rights will be exercisable only if a person or group acquires
beneficial ownership of 15% or more of the Company's common stock, or announces
a tender or exchange offer upon consummation of which, such person or group
would beneficially own 15% or more of the common shares of the Company. The
rights are not triggered by present beneficial holders of 15% or more of the
common stock unless they subsequently increase their beneficial holdings.

         If a person or group becomes a beneficial owner of 15% or more of the
Company's common shares, then each right not owned by the person or group
entitles its holder to purchase shares of Company common stock at the right's
then current exercise price (or in certain circumstances as determined by the
Company, a combination of cash, property, common shares or other securities),
having a value of twice the right's exercise price of $140. (For example, at a
market price of $30 per share, each right would entitle its holder to purchase
approximately nine shares of Company common stock.) For purposes of determining
the value of the participating preferred stock, each one one-hundredth of a
share will be considered to be equivalent in value to one share of Company
common stock.

         In addition, if the Company is involved in a merger or business
combination transaction with another person in which the Company is not the
surviving corporation, each right that has not previously been exercised will
entitle its holder to purchase, at the
<PAGE>   3
right's then-current exercise price, common shares of such other person having a
value of twice the right's exercise price.

         The Company may terminate the rights, without payment to the holders,
at any time until the close of business on the tenth business day following an
announcement by the Company that a person or group has become the beneficial
owner of 15% or more of the Company's common stock.

         Details of the shareholder protection rights agreement are outlined in
a letter which will be mailed to all shareholders of record at the close of
business on June 2, 1997.

         Renal Care Group, Inc. is a nephrology services company 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. The Company

in addition to providing acute dialysis services in 51 hospitals.
