<PAGE>

                               Rights Agreement

     Rights Agreement, dated as of May 11, 1999, by and between LifePoint
Hospitals, Inc., a Delaware corporation (the "Company"), and National City Bank
(the "Rights Agent").

     The Board of Directors of the Company has authorized and directed the
issuance of one preferred share purchase right (a "Right") for each Common Share
to be issued in the distribution of Common Shares effective May 11, 1999 (the
"Record Date"), as such distribution is described in the Company's Registration
Statement on Form 10 (File No. 0-29818), dated April 27, 1999 (the "Spin-Off").
Each Right represents the right to purchase one one-thousandth of a Preferred
Share, upon the terms and subject to the conditions herein set forth.  The Board
of Directors of the Company has further authorized and directed the issuance of
one Right with respect to each Common Share that shall become outstanding
between the Record Date and the earliest of the Distribution Date, the
Redemption Date and the Expiration Date.

     Accordingly, in consideration of the premises and the mutual agreements
herein set forth, the parties hereby agree as follows:

     Section 1.  Certain Definitions. For purposes of this Rights Agreement, the
                 -------------------
following terms have the meanings indicated:

     (a)  "Acquiring Person" shall mean any Person who or which, together with
all Affiliates and Associates of such Person, shall be the Beneficial Owner of
15% or more of the Common Shares then outstanding, but shall not include (i) the
Company, any Subsidiary of the Company, any employee benefit plan of the Company
or of any Subsidiary of the Company, or any entity holding Common Shares for or
pursuant to the terms of any such plan, (ii) any Person who or which becomes the
Beneficial Owner of 15% or more of the Common Shares then outstanding as the
result of a reduction in the outstanding Common Shares resulting from
acquisition of Common Shares by the Company approved by the Board of Directors,
unless and until such Person becomes the Beneficial Owner of any additional
Common Shares, other than pursuant to a stock dividend or stock split, (iii) any
Person who or which the Board of Directors of the Company determines, in good
faith, became an Acquiring Person inadvertently, if such Person divests as
promptly as practicable a sufficient number of Common Shares so that such Person
would no longer be an Acquiring Person or (iv) any Person who or which the Board
of Directors of the Company determines, prior to the time such Person would
otherwise be an Acquiring Person, should be exempted from the definition of
Acquiring Person, provided that the Board of Directors may make such exemption
subject to such conditions, if any, which the Board may determine.
Notwithstanding anything in this paragraph (a) to the contrary, neither
Columbia/HCA Healthcare Corporation nor any of its affiliates shall be deemed to
be an Acquiring Person as a result of its ownership of Common Shares prior to
the Spin-Off.
<PAGE>

          (b)  "Affiliate" and "Associate" shall have the respective meanings
ascribed to such terms in Rule 12b-2 under the Exchange Act.

          (c)  A Person shall be deemed the "Beneficial Owner" of and shall be
deemed to "Beneficially Own" any securities:

               (i)    which such Person or any of such Person's Affiliates or
Associates beneficially owns, directly or indirectly;

               (ii)   which such Person or any of such Person's Affiliates or
Associates has (A) the right to acquire (whether such right is exercisable
immediately or only after the passage of time) pursuant to any agreement,
arrangement or understanding (other than customary agreements with and between
underwriters and selling group members with respect to a bona fide public
offering of securities), or upon the exercise of conversion rights,
exchange rights, rights (other than these Rights), warrants or options, or
otherwise; provided, however, that a Person shall not be deemed the
           --------  -------
Beneficial Owner of, or to Beneficially Own, securities tendered pursuant to a
tender or exchange offer made by or on behalf of such Person or any of such
Person's Affiliates or Associates until such tendered securities are accepted
for purchase or exchange or (B) the right to vote pursuant to any agreement,
arrangement or understanding; provided, however, that a Person shall not be
                              --------  -------
deemed the Beneficial Owner of, or to Beneficially Own, any security if the
agreement, arrangement or understanding to vote such security (1) arises solely
from a revocable proxy or consent given to such Person in response to a public
proxy or consent solicitation made pursuant to, and in accordance with, the
applicable rules and regulations promulgated under the Exchange Act and (2) is
not also then reportable on Schedule 13D under the Exchange Act (or any
comparable or successor report); or

               (iii)  which are beneficially owned, directly or indirectly, by
any other Person with which such Person or any of such Person's Affiliates or
Associates has any agreement, arrangement or understanding (other than customary
agreements with and between underwriters and selling group members with respect
to a bona fide public offering of securities) for the purpose of acquiring,
holding, voting (except to the extent contemplated by the proviso to Section
1(c)(ii)(B)) or disposing of any securities of the Company.

     Notwithstanding anything in this definition of Beneficial Ownership to the
contrary, the phrase "then outstanding," when used with reference to a Person's
Beneficial Ownership of securities of the Company, shall mean the number of such
securities then issued and outstanding together with the number of such
securities not then actually issued and outstanding which such Person would be
deemed to Beneficially Own hereunder.

          (d)  A determination, approval, consent or other action of the "Board
     of Directors" shall require approval or consent of a majority of the Board
     of Directors of the Company.

     Section 3. Issue of Right Certificates. (a) Until the earlier of the Close
                ---------------------------
of Business on the tenth day (or such other date as the Board of Directors of
the Company shall determine) after (i) the Stock Acquisition Date or (ii) the
date of the commencement by any Person (other than the Company, any Subsidiary
of the Company, any employee benefit plan of the Company or of any Subsidiary of
the Company or any entity holding Common Shares for or pursuant to the terms of
any such plan) of, or of the first public announcement of the intention of any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or of any Subsidiary of the Company or any entity
holding Common Shares for or pursuant to the terms of any such plan) to
commence, a tender or exchange offer the consummation of which would result in
any Person becoming an Acquiring Person (including any such date which is after
the date of this Rights Agreement and prior to the issuance of the Rights; the
earlier of such dates being herein referred to as the "Distribution Date"), (x)
the Rights will be evidenced (subject to the provisions of Section 3(b) hereof)
by the certificates for Common Shares registered in the names of the holders
thereof (which certificates shall also be deemed to be Right Certificates) and
not by separate Right Certificates and (y) the right to receive Right
Certificates will be transferable only in connection with the transfer of Common
Shares. As soon as practicable after the Distribution Date, the Company will
prepare and execute, the Rights Agent will countersign, and the Company will
send or cause to be sent (and the Rights Agent will, if requested, send) by
first-class, insured, postage-prepaid mail, to each record holder of Common
Shares as of the Close of Business on the Distribution Date, at the address of
such holder shown on the records of the Company, a Right Certificate, in
substantially the form of Exhibit A hereto (a "Right Certificate"), evidencing
one Right for each Common Share so held. As of the Distribution Date, the Rights
will be evidenced solely by such Right Certificates.

          (b)  The Company will make available, as promptly as practicable
following the Record Date, a Summary of Rights to Purchase Preferred Shares, in
substantially the form of Exhibit B hereto, to any holder of Rights who may so
request from time to time prior to the Expiration Date. With respect to
certificates for Common Shares outstanding as of the Record Date, until the
Distribution Date, the Rights will be evidenced by such certificates and the
registered holders of the Common Shares shall also be the registered holders of
the associated Rights. Until the Distribution Date (or the earlier of the
Redemption Date or the Expiration Date), the surrender for transfer of any
certificate for Common Shares in respect of which Rights have been issued shall
also constitute the transfer of the Rights associated with such Common Shares.

          (c)  Rights shall be issued in respect of all Common Shares which are
issued (whether originally issued or from the Company's treasury) after the
Record Date but prior to the earliest of the Distribution Date, the Redemption
Date or the Expiration Date. Certificates representing such Common Shares shall
bear the following legend:

          This certificate also evidences and entitles the holder hereof to
          certain rights as set forth in a Rights Agreement between LifePoint
          Hospitals, Inc. (the "Company") and the Rights Agent thereunder (the
          "Rights Agreement"), the terms of which are hereby incorporated herein
          by

                                       5
<PAGE>

          reference and a copy of which is on file at the principal offices
          of the Company.   Under certain circumstances, as set forth in the
          Rights Agreement, such rights will be evidenced by separate
          certificates and will no longer be evidenced by this certificate.
          The Company will mail to the holder of this certificate a copy of the
          Rights Agreement without charge after receipt of a written request
          therefor.   Under certain circumstances, as set forth in the Rights
          Agreement, rights issued to any person who becomes an Acquiring Person
          (as defined in the rights agreement), including such rights held by a
          subsequent holder, may become null and void.

     With respect to such certificates containing the foregoing legend, until
the Distribution Date, the Rights associated with the Common Shares represented
by such certificates shall be evidenced by such certificates alone, and the
surrender for transfer of any such certificate shall also constitute the
transfer of the Rights associated with the Common Shares represented thereby.
In the event that the Company purchases or acquires any Common Shares after the
Record Date but prior to the Distribution Date, any Rights associated with such
Common Shares shall be deemed cancelled and retired so that the Company shall
not be entitled to exercise any Rights associated with the Common Shares which
are no longer outstanding.

     Section 4. Form of Right Certificates. The Right Certificates (and the
                --------------------------
forms of election to purchase Preferred Shares and of assignment to be printed
on the reverse thereof) shall be substantially the same as Exhibit A hereto and
may have 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 Rights Agreement, or as may be
required to comply with any applicable law or with any rule or regulation made
pursuant thereto or with any rule or regulation of any stock exchange or
automated quotation system on which the Rights may from time to time be listed,
or to conform to usage. Subject to the provisions of Sections 11 and 22 hereof,
the Right Certificates shall entitle the holders thereof to purchase such number
of one one-thousandths of a Preferred Share as shall be set forth therein at the
price per one one-thousandth of a Preferred Share set forth therein, but the
number of one one-thousandths of a Preferred Share and the Purchase Price shall
be subject to adjustment as provided herein.

     Section 5.  Countersignature and Registration. (a) The Right Certificates
                 ---------------------------------
shall be executed on behalf of the Company by its Chairman of the Board, its
Chief Executive Officer, its President, any of its Vice Presidents or its
Treasurer, either manually or by facsimile signature, shall have affixed thereto
the Company's seal or a facsimile thereof, and shall be attested by the
Secretary or an Assistant Secretary of the Company, either manually or by
facsimile signature. The Right Certificates shall be countersigned by the Rights
Agent, either manually or by facsimile signature, and shall not be valid for any
purpose unless so countersigned. In case any officer of the Company who shall
have signed any of the Right Certificates shall cease to be such officer of the
Company before countersignature by the Rights Agent and issuance and delivery by
the Company, such

                                       6
<PAGE>

Right Certificates, nevertheless, may be countersigned by the Rights Agent and
issued and delivered by the Company with the same force and effect as though the
Person who signed such Right Certificates had not ceased to be such officer of
the Company; and any Right Certificate may be signed on behalf of the Company by
any Person who, at the actual date of the execution of such Right Certificate,
shall be a proper officer of the Company to sign such Right Certificate although
at the date of the execution of this Rights Agreement any such Person was not
such an officer.

          (b)  Following the Distribution Date, the Rights Agent will keep or
cause to be kept, at its principal office, books for registration and transfer
of the Right Certificates issued hereunder. Such books shall show the names and
addresses of the respective holders of the Right Certificates, the number of
Rights evidenced on its face by each of the Right Certificates and the date of
each of the Right Certificates.

     Section 6.  Transfer, Split Up, Combination and Exchange of Right
                 -----------------------------------------------------
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.
---------------------------------------------------------------------

          (a)  Subject to the provisions of Section 14 hereof, at any time after
the Close of Business on the Distribution Date, and at or prior to the Close of
Business on the earlier of the Redemption Date or the Expiration Date, any Right
Certificate or Right Certificates (other than Right Certificates representing
Rights that have become void pursuant to Section 11(a)(ii) hereof or that have
been exchanged pursuant to Section 24 hereof) may be transferred, split up,
combined or exchanged for another Right Certificate or Right Certificates
entitling the registered holder to purchase a like number of one one-thousandths
of a Preferred Share as the Right Certificate or Right Certificates surrendered
then entitled such holder to purchase. Any registered holder desiring to
transfer, split up, combine or exchange any Right Certificate or Right
Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the principal office of the
Rights Agent. Thereupon the Rights Agent shall countersign and deliver to the
Person entitled thereto a Right Certificate or Right Certificates, as the case
may be, as so requested. The Company may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates.

          (b)  Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Right Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them, and, at the Company's request,
reimbursement to the Company and the Rights Agent of all reasonable expenses
incidental thereto, and upon surrender to the Rights Agent and cancellation of
the Right Certificate if mutilated, the Company will make and deliver a new
Right Certificate of like tenor to the Rights Agent for delivery to the
registered holder in lieu of the Right Certificate so lost, stolen, destroyed or
mutilated.

                                       7

     Section 7.  Exercise of Rights; Purchase Price; Expiration Date of Rights.
                 -------------------------------------------------------------

          (a)  The registered holder of any Right Certificate may exercise the
Rights evidenced thereby (except as otherwise provided herein), in whole or in
part, at any time after the Distribution Date, upon surrender of the Right
Certificate, with the form of election to purchase on the reverse side thereof
duly executed, to the Rights Agent at the principal office of the Rights Agent,
together with payment of the Purchase Price for each one one-thousandth of a
Preferred Share as to which the Rights are exercised, at or prior to the
earliest of (i) the Expiration Date, (ii) the Redemption Date or (iii) the time
at which such Rights are exchanged as provided in Section 24 hereof.

          (b)  The Purchase Price shall be payable in lawful money of the United
States of America in accordance with paragraph (c) below.

          (c)  Upon receipt of a Right Certificate representing exercisable
Rights, with the form of election to purchase duly executed, accompanied by
payment of the Purchase Price for the shares to be purchased and an amount equal
to any applicable transfer tax required to be paid by the holder of such Right
Certificate in accordance with Section 9 hereof by certified check, cashier's
check or money order payable to the order of the Company, the Rights Agent shall
thereupon promptly (i) (A) requisition from any transfer agent of the Preferred
Shares certificates for the number of Preferred Shares to be purchased and the
Company hereby irrevocably authorizes any such transfer agent to comply with all
such requests or (B) requisition from the depositary agent depositary receipts
representing such number of one one-thousandths of a Preferred Share as are to
be purchased (in which case certificates for the Preferred Shares represented by
such receipts shall be deposited by the transfer agent of the Preferred Shares
with such depositary agent) and the Company hereby directs such depositary agent
to comply with such request; (ii) when appropriate, requisition from the Company
the amount of cash to be paid in lieu of issuance of fractional shares in
accordance with Section 14 hereof; (iii) promptly after receipt of such
certificates or depositary receipts, cause the same to be delivered to or upon
the order of the registered holder of such Right Certificate, registered in such
name or names as may be designated by such holder; and (iv) when appropriate,
after receipt, promptly deliver such cash to or upon the order of the registered
holder of such Right Certificate.

          (d)  In case the registered holder of any Right Certificate shall
exercise less than all the Rights evidenced thereby, a new Right Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent to the registered holder of such Right Certificate or to
such holder's duly authorized assigns, subject to the provisions of Section 14
hereof.

     Section 8.  Cancellation and Destruction of Right Certificates. All Right
                 --------------------------------------------------
Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered to the Rights Agent, shall be cancelled by it, and no Right
Certificates shall be issued in lieu thereof except as

                                       8
<PAGE>

expressly permitted by any of the provisions of this Rights Agreement. The
Company shall deliver to the Rights Agent for cancellation and retirement, and
the Rights Agent shall so cancel and retire, any other Right Certificate
purchased or acquired by the Company otherwise than upon the exercise thereof.
The Rights Agent shall deliver all cancelled Right Certificates to the Company,
or shall, at the written request of the Company, destroy such cancelled Right
Certificates, and, in such case, shall deliver a certificate of destruction
thereof to the Company.

     Section 9.  Availability of Preferred Shares.
                 --------------------------------
          (a)    The Company covenants and agrees that it will cause to be
reserved and kept available out of its authorized and unissued Preferred Shares
or any Preferred Shares held in its treasury, the number of Preferred Shares
that will be sufficient to permit the exercise in full of all outstanding Rights
in accordance with Section 7. The Company covenants and agrees that it will take
all such action as may be necessary to ensure that all securities delivered upon
exercise of Rights shall, at the time of delivery of the certificates for such
securities (subject to payment of the Purchase Price), be duly and validly
authorized and issued and fully paid and nonassessable.

          (b)    The Company further covenants and agrees that it will pay when
due and payable any and all federal and state transfer taxes and charges which
may be payable in respect of the issuance or delivery of the Right Certificates
or of any Preferred Shares upon the exercise of Rights. The Company shall not,
however, be required to pay any transfer tax which may be payable in respect of
any transfer or delivery of Right Certificates to a Person other than, or the
issuance or delivery of certificates or depositary receipts for the Preferred
Shares in a name other than that of, the registered holder of the Right
Certificate evidencing Rights surrendered for exercise or to issue or to deliver
any certificates or depositary receipts for Preferred Shares upon the exercise
of any Rights until any such tax shall have been paid (any such tax being
payable by the holder of such Right Certificate at the time of surrender) or
until it has been established to the Company's reasonable satisfaction that no
such tax is due.

          (c)    The Company will use its best efforts to ensure that any
securities issued pursuant hereto are issued in compliance with all applicable
laws.

     Section 10. Preferred Shares Record Date. Each Person in whose name any
                 ----------------------------
certificate for Preferred Shares is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of record of the Preferred
Shares represented thereby on, and such certificate shall be dated, the date
upon which the Right Certificate evidencing such Rights was duly surrendered and
payment of the Purchase Price (and any applicable transfer taxes) was made;
provided, however, that if the date of such surrender and payment is a date upon
--------  -------
which the Preferred Shares 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
Preferred Shares transfer books of the Company are open. Prior to the exercise
of the Rights evidenced thereby, the holder of a Right Certificate shall not be
entitled to any

                                       9
<PAGE>

rights of a holder of Preferred Shares for which the Rights shall be
exercisable, including, without limitation, the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights, and shall
not be entitled to receive any notice of any proceedings of the Company, except
as provided herein.

     Section 11. Adjustment of Purchase Price, Number of Shares or Number of
                 -----------------------------------------------------------
Rights. The Purchase Price, the number of Preferred Shares covered by each Right
------
and the number of Rights outstanding are subject to adjustment from time to time
as provided in this Section 11.

          (a) (i)   In the event the Company shall at any time after the date of
this Rights Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine
the outstanding Preferred Shares into a smaller number of Preferred Shares or
(D) issue any shares of its capital stock in a reclassification of the Preferred
Shares (including any such reclassification in connection with a consolidation
or merger in which the Company is the continuing or surviving corporation),
except as otherwise provided in this Section 11(a), the Purchase Price in effect
at the time of the record date for such dividend or of the effective date of
such subdivision, combination or reclassification, and the number and kind of
shares of capital stock issuable on such date, shall be proportionately adjusted
so that the holder of any Right exercised after such time shall be entitled to
receive the aggregate number and kind of shares of capital stock which, if such
Right had been exercised immediately prior to such date and at a time when the
Preferred Shares transfer books of the Company were open, such holder would have
owned upon such exercise and been entitled to receive by virtue of such
dividend, subdivision, combination or reclassification; provided, however, that
                                                        --------  -------
in no event shall the consideration to be paid upon the exercise of one Right be
less than the aggregate par value of the shares of capital stock of the Company
issuable upon exercise of one Right.

              (ii)  Subject to Section 24 of this Rights Agreement, in the event
any Person becomes an Acquiring Person, each holder of a Right shall thereafter
have a right to receive, upon exercise thereof at a price equal to the then
current Purchase Price multiplied by the number of one one-thousandths of a
Preferred Share for which a Right is then exercisable, in accordance with the
terms of this Rights Agreement and in lieu of Preferred Shares, such number of
Common Shares as shall equal the result obtained by (A) multiplying the then-
current Purchase Price by the number of one one-thousandths of a Preferred Share
for which a Right is then exercisable and dividing that product by (B) 50% of
the then current per share market price of the Company's Common Shares
(determined pursuant to Section 11(d) hereof) on the date of the occurrence of
such event. In the event that any Person shall become an Acquiring Person and
the Rights shall then be outstanding, the Company shall not take any action
which would eliminate or diminish the benefits intended to be afforded by the
Rights.

     Notwithstanding anything in this Agreement to the contrary, from and after
the occurrence of such event, any Rights that are or were acquired or
Beneficially Owned by any Acquiring Person (or any Associate or Affiliate of
such Acquiring Person) shall be

                                      10
<PAGE>

void and any holder of such Rights shall thereafter have no right to exercise
such Rights under any provision of this Rights Agreement. No Right Certificate
shall be issued pursuant to Section 3 that represents Rights Beneficially Owned
by an Acquiring Person whose Rights would be void pursuant to the preceding
sentence or any Associate or Affiliate thereof; no Right Certificate shall be
issued at any time upon the transfer of any Rights to an Acquiring Person whose
Rights would be void pursuant to the preceding sentence or any Associate or
Affiliate thereof or to any nominee of such Acquiring Person, Associate or
Affiliate; and any Right Certificate delivered to the Rights Agent for transfer
to an Acquiring Person whose Rights would be void pursuant to the preceding
sentence shall be cancelled.

               (iii)  If there shall not be sufficient Common Shares issued but
not outstanding or authorized but unissued to permit the exercise in full of the
Rights in accordance with the foregoing subparagraph (ii), the Company shall
take all such action as may be necessary to authorize additional Common Shares
for issuance upon exercise of the Rights. If the Company shall, after good faith
effort, be unable to take all such action as may be necessary to authorize such
additional Common Shares, the Company shall substitute, for each Common Share
that would otherwise be issuable upon exercise of a Right, a number of Preferred
Shares or fraction thereof (or a security with substantially similar rights,
privileges, preferences, voting power and economic rights) such that the current
per share market price of one Preferred Share (or such other security)
multiplied by such number or fraction is equal to the current per share market
price of one Common Share as of the date of issuance of such Preferred Shares or
fraction thereof (or other security).

          (b)  In case the Company shall fix a record date for the issuance of
rights, options or warrants to all holders of Preferred Shares entitling them
(for a period expiring within 45 calendar days after such record date) to
subscribe for or purchase Preferred Shares (or shares having the same rights,
privileges and preferences as the Preferred Shares ("equivalent preferred
shares")) or securities convertible into Preferred Shares or equivalent
preferred shares at a price per Preferred Share or equivalent preferred share
(or having a conversion price per share, if a security convertible into
Preferred Shares or equivalent preferred shares) less than the then current per
share market price of the Preferred Shares on such record date, the Purchase
Price to be in effect after such record date shall be determined by multiplying
the Purchase Price in effect immediately prior to such record date by a
fraction, the numerator of which shall be the number of Preferred Shares
outstanding on such record date plus the number of Preferred Shares which the
aggregate offering price of the total number of Preferred Shares and/or
equivalent preferred shares so to be offered (and/or the aggregate initial
conversion price of the convertible securities so to be offered) would purchase
at such current market price and the denominator of which shall be the number of
Preferred Shares outstanding on such record date plus the number of additional
Preferred Shares and/or equivalent preferred shares to be offered for
subscription or purchase (or into which the convertible securities so to be
offered are initially convertible); provided, however, that in no event shall
                                    --------  -------
the consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. In case such subscription price may be paid in a

                                      11
<PAGE>

consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent and shall be binding on the Rights Agent and the
holders of the Rights. Preferred Shares owned by or held for the account of the
Company shall not be deemed outstanding for the purpose of any such computation.
Such adjustment shall be made successively whenever such a record date is fixed;
and in the event that such rights, options or warrants are not so issued, the
Purchase Price shall be adjusted to be the Purchase Price which would then be in
effect if such record date had not been fixed.

          (c)  In case the Company shall fix a record date for the making of a
distribution to all holders of the Preferred Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) or subscription rights or warrants (excluding those referred
to in Section 11(b) hereof), the Purchase Price to be in effect after such
record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the then current per share market price of the Preferred Shares on such
record date, less the fair market value (as determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent and shall be binding on the Rights Agent
and holders of the Rights) of the portion of the assets or evidences of
indebtedness so to be distributed or of such subscription rights or warrants
applicable to one Preferred Share and the denominator of which shall be such
current per share market price of the Preferred Shares; provided, however, that
                                                        --------  -------
in no event shall the consideration to be paid upon the exercise of one Right be
less than the aggregate par value of the shares of capital stock of the Company
to be issued upon exercise of one Right. Such adjustments shall be made
successively whenever such a record date is fixed; and in the event that such
distribution is not so made, the Purchase Price shall again be adjusted to be
the Purchase Price which would then be in effect if such record date had not
been fixed.

          (d)  (i)  For the purpose of any computation hereunder, the "current
per share market price" of any security (a "Security" for the purpose of this
Section 11(d)(i)) on any date shall be deemed to be the average of the daily
closing prices per share of such Security for the 30 consecutive Trading Days
immediately prior to such date; provided, however, that in the event that the
                                --------  -------
current per share market price of the Security is determined during a period
following the announcement by the issuer of such Security of (A) a dividend or
distribution on such Security payable in shares of such Security or securities
convertible into such shares, or (B) any subdivision, combination or
reclassification of such Security and prior to the expiration of 30 Trading Days
after the ex-dividend date for such dividend or distribution, or the record date
for such subdivision, combination or reclassification, then, and in each such
case, the current per share market price shall be appropriately adjusted to
reflect the current market price per share equivalent of such Security. The
closing price for each day shall be the last sale price, regular way, or, in
case no such sale takes place on such day, the average of the

                                      12
<PAGE>

closing bid and asked prices, regular way, in either case, as reported in the
principal consolidated transaction reporting system with respect to securities
listed or admitted to trading on the New York Stock Exchange or, if the Security
is not listed or admitted to trading on the New York Stock Exchange, as reported
in the principal consolidated transaction reporting system with respect to
securities listed on the principal national securities exchange on which the
Security is listed or admitted to trading or, if the Security is not listed or
admitted to trading on any national securities exchange, the last quoted price
or, if not so quoted, the average of the high bid and low asked prices in the
over-the-counter market, as reported by the NASDAQ or such other system then in
use, or, if on any such date the Security is not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Security selected by the Board
of Directors of the Company. If on any such date no such market maker is making
a market in the Security, the fair value of the Security on such date as
determined in good faith by the Board of Directors of the Company shall be used.
The term "Trading Day" shall mean a day on which the principal national
securities exchange on which the Security is listed or admitted to trading is
open for the transaction of business or, if the Security is not listed or
admitted to trading on any national securities exchange, a Business Day.

                    (ii)  For the purpose of any computation hereunder, the
     "current per share market price" of the Preferred Shares shall be
     determined in accordance with the method set forth in Section 11(d)(i). If
     the Preferred Shares are not publicly traded, the "current per share market
     price" of the Preferred Shares shall be conclusively deemed to be the
     current per share market price of the Common Shares as determined pursuant
     to Section 11(d)(i) (appropriately adjusted to reflect any stock split,
     stock dividend or similar transaction occurring after the date hereof),
     multiplied by one thousand. If neither the Common Shares nor the Preferred
     Shares are publicly held or so listed or traded, "current per share market
     price" shall mean the fair value per share as determined in good faith by
     the Board of Directors of the Company, whose determination shall be
     described in a statement filed with the Rights Agent.

               (e)  No adjustment in the Purchase Price shall be required unless
such adjustment would require an increase or decrease of at least 1% in the
Purchase Price; provided, however, that any adjustments which by reason of this
Section 11(e) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations under this Section
11 shall be made to the nearest cent or to the nearest one-millionth of a
Preferred Share or one ten-thousandth of any other share or security as the case
may be. Notwithstanding the first sentence of this Section 11(e), any adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
years from the date of the transaction which requires such adjustment or (ii)
the date of the expiration of the right to exercise any Rights.

               (f)  If, as a result of an adjustment made pursuant to Section
11(a) hereof, the holder of any Right thereafter exercised shall become entitled
to receive any shares of capital stock of the Company other than Preferred
Shares, thereafter the number of such other shares so receivable upon exercise
of any Right shall be subject to

                                      13
<PAGE>

adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the Preferred Shares contained in
Section 11(a) through (c), inclusive, and the provisions of Sections 7, 9, 10
and 13 with respect to the Preferred Shares shall apply on like terms to any
such other shares.

               (g)  All Rights originally issued by the Company subsequent to
any adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of one one-thousandths of a
Preferred Share purchasable from time to time hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

               (h)  Unless the Company shall have exercised its election as
provided in Section 11(i), upon each adjustment of the Purchase Price as a
result of the calculations made in Sections 11(b) and (c), each Right
outstanding immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase, at the adjusted Purchase Price, that number of
one one-thousandths of a Preferred Share (calculated to the nearest one
millionth of a Preferred Share) obtained by (A) multiplying (x) the number of
one one-thousandths of a share covered by a Right immediately prior to this
adjustment by (y) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price and (B) dividing the product so obtained by the
Purchase Price in effect immediately after such adjustment of the Purchase
Price.

               (i)  The Company may elect on or after the date of any adjustment
of the Purchase Price to adjust the number of Rights in substitution for any
adjustment in the number of one one-thousandths of a Preferred Share purchasable
upon the exercise of a Right. Each of the Rights outstanding after such
adjustment of the number of Rights shall be exercisable for the number of one
one-thousandths of a Preferred Share for which a Right was exercisable
immediately prior to such adjustment. Each Right held of record prior to such
adjustment of the number of Rights shall become that number of Rights
(calculated to the nearest one millionth) obtained by dividing the Purchase
Price in effect immediately prior to adjustment of the Purchase Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The
Company shall make a public announcement of its election to adjust the number of
Rights, indicating the record date for the adjustment, and, if known at the
time, the amount of the adjustment to be made. This record date may be the date
on which the Purchase Price is adjusted or any day thereafter, but, if the Right
Certificates have been issued, shall be at least 10 days later than the date of
the public announcement. If Right Certificates have been issued, upon each
adjustment of the number of Rights pursuant to this Section 11(i), the Company
shall, as promptly as practicable, cause to be distributed to holders of record
of Right Certificates on such record date Right Certificates evidencing, subject
to Section 14 hereof, the additional Rights to which such holders shall be
entitled as a result of such adjustment, or, at the option of the Company, shall
cause to be distributed to such holders of record in substitution and
replacement for the Right Certificates held by such holders prior to the date of
adjustment, and upon surrender thereof, if required by the Company, new Right
Certificates evidencing all the Rights to which such holders shall be entitled
after such adjustment. Right Certificates so to be distributed shall be issued,
executed

                                      14
<PAGE>

and countersigned in the manner provided for herein and shall be registered in
the names of the holders of record of Right Certificates on the record date
specified in the public announcement.

               (j)  Irrespective of any adjustment or change in the Purchase
Price or the number of one one-thousandths of a Preferred Share issuable upon
the exercise of the Rights, the Right Certificates theretofore and thereafter
issued may continue to express the Purchase Price and the number of one one-
thousandths of a Preferred Share which were expressed in the initial Right
Certificates issued hereunder.

               (k)  Before taking any action that would cause an adjustment
reducing the Purchase Price below one one-thousandth of the then par value, if
any, of the Preferred Shares issuable upon exercise of the Rights, the Company
shall take any corporate action which may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue fully paid and
nonassessable Preferred Shares at such adjusted Purchase Price.

               (l)  In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuing to the holder of any Right exercised after such record date of
the Preferred Shares and other capital stock or securities of the Company, if
any, issuable upon such exercise over and above the Preferred Shares and other
capital stock or securities of the Company, if any, issuable upon such exercise
on the basis of the Purchase Price in effect prior to such adjustment; provided,
however, that the Company shall deliver to such holder a due bill or other
appropriate instrument evidencing such holder's right to receive such additional
shares upon the occurrence of the event requiring such adjustment.

               (m)  Anything in this Section 11 to the contrary notwithstanding,
the Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that, it, in its sole discretion, shall determine to be advisable in
order that any consolidation or subdivision of the Preferred Shares, issuance
wholly for cash of any Preferred Shares at less than the current market price,
issuance wholly for cash of Preferred Shares or securities which by their terms
are convertible into or exchangeable for Preferred Shares, dividends on
Preferred Shares payable in Preferred Shares or issuance of rights, options or
warrants referred to hereinabove in Section 11(b), hereafter made by the Company
to holders of its Preferred Shares shall not be taxable to such stockholders.

               (n)  In the event that at any time after the date of this Rights
Agreement and prior to the Distribution Date, the Company shall (i) declare or
pay any dividend on the Common Shares payable in Common Shares or (ii) effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares)
into a greater or lesser number of Common Shares, then in any such case (A) the
number of one one-thousandths of a Preferred Share purchasable after such event
upon proper exercise of each Right shall be determined by multiplying

                                      15
<PAGE>

the number of one one-thousandths of a Preferred Share so purchasable
immediately prior to such event by a fraction, the numerator of which is the
number of Common Shares outstanding immediately before such event and the
denominator of which is the number of Common Shares outstanding immediately
after such event, and (B) each Common Share outstanding immediately after such
event shall have issued with respect to it that number of Rights which each
Common Share outstanding immediately prior to such event had issued with respect
to it. The adjustments provided for in this Section 11(n) shall be made
successively whenever such a dividend is declared or paid or such a subdivision,
combination or consolidation is effected.

     Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
                 ----------------------------------------------------------
Whenever an adjustment is made as provided in Sections 11 or 13 hereof, the
Company shall promptly (a) prepare a certificate setting forth such adjustment,
and a brief statement of the facts accounting for such adjustment, (b) file with
the Rights Agent and with each transfer agent for the Common Shares or the
Preferred Shares a copy of such certificate and (c) if a Distribution Date has
occurred, mail a brief summary thereof to each holder of a Right Certificate in
accordance with Section 25 hereof.

     Section 13. Consolidation, Merger or Sale or Transfer of Assets or Earning
                 --------------------------------------------------------------
Power. In the event, directly or indirectly, at any time after a Person has
-----
become an Acquiring Person, (a) the Company shall consolidate with, or merge
with and into, any other Person, (b) any Person shall consolidate with the
Company, or merge with and into the Company and the Company shall be the
continuing or surviving corporation of such merger and, in connection with such
merger, all or part of the Common Shares shall be changed into or exchanged for
stock or other securities of any other Person (or the Company) or cash or any
other property or (c) the Company shall sell or otherwise transfer (or one or
more of its Subsidiaries shall sell or otherwise transfer), in one or more
transactions, assets or earning power aggregating 50% or more of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person other than the Company or one or more of its wholly owned
Subsidiaries, then, and in each such case, proper provision shall be made so
that

                 (i)   each holder of a Right (except as otherwise provided
herein) shall thereafter have the right to receive, upon the exercise thereof at
a price equal to the then-current Purchase Price multiplied by the number of one
one-thousandths of a Preferred Share for which a Right is then exercisable, in
accordance with the terms of this Rights Agreement and in lieu of Preferred
Shares, such number of Common Shares of such other Person (including the Company
as successor thereto or as the surviving corporation) as shall equal the result
obtained by (A) multiplying the then current Purchase Price by the number of one
one-thousandths of a Preferred Share for which a Right is then exercisable and
dividing that product by (B) 50% of the then current per share market price of
the Common Shares of such other Person (determined pursuant to Section 11(d)
hereof) on the date of consummation of such consolidation, merger, sale or
transfer;

                                      16
<PAGE>

                 (ii)   the issuer of such Common Shares shall thereafter be
liable for, and shall assume, by virtue of such consolidation, merger, sale or
transfer, all the obligations and duties of the Company pursuant to this Rights
Agreement;

                 (iii)  the term "Company" shall thereafter be deemed to refer
to such issuer; and

                 (iv)   such issuer shall take such steps (including, but not
limited to, the reservation of a sufficient number of its Common Shares in
accordance with Section 9 hereof) in connection with such consummation as may be
necessary to assure that the provisions hereof shall thereafter be applicable,
as nearly as reasonably may be, in relation to the Common Shares thereafter
deliverable upon the exercise of the Rights.

     The Company shall not consummate any such consolidation, merger, sale or
transfer unless prior thereto the Company and such issuer shall have executed
and delivered to the Rights Agent a supplemental agreement so providing.  The
Company shall not enter into any transaction of the kind referred to in this
Section 13 if at the time of such transaction there are any rights, warrants,
instruments or securities outstanding or any agreements or arrangements which,
as a result of the consummation of such transaction, would eliminate or
substantially diminish the benefits intended to be afforded by the Rights.  The
provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers.

     Section 14. Fractional Rights and Fractional Shares.
                 ---------------------------------------

             (a) The Company shall not be required to issue fractions of Rights
or to distribute Right Certificates which evidence fractional Rights. In lieu of
such fractional Rights, there shall be paid to the registered holders of the
Right Certificates with regard to which such fractional Rights would otherwise
be issuable, an amount in cash equal to the same fraction of the current market
value of a whole Right. For the purposes of this Section 14(a), the current
market value of a whole Right shall be the closing price of the Rights for the
Trading Day immediately prior to the date on which such fractional Rights would
have been otherwise issuable. The closing price for any day shall be the last
sale price, regular way, or, in case no such sale takes place on such day, the
average of the closing bid and asked prices, regular way, in either case, as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if the Rights are not listed or admitted to trading on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national securities exchange
on which the Rights are listed or admitted to trading or, if the Rights are not
listed or admitted to trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by NASDAQ or such other
system then in use or, if on any such date the Rights are not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Rights selected by the Board of
Directors of the Company. If on any such

                                      17
<PAGE>

date no such market maker is making a market in the Rights, the fair value of
the Rights on such date as determined in good faith by the Board of Directors of
the Company shall be used.

          (b)  The Company shall not be required to issue fractions of Preferred
Shares (other than fractions which are integral multiples of one one-thousandth
of a Preferred Share) upon exercise of the Rights or to distribute certificates
which evidence fractional Preferred Shares (other than fractions which are
integral multiples of one one-thousandth of a Preferred Share). Fractions of
Preferred Shares in integral multiples of one one-thousandth of a Preferred
Share may, at the election of the Company, be evidenced by depositary receipts,
pursuant to an appropriate agreement between the Company and a depositary
selected by it; provided that such agreement shall provide that the holders of
                --------
such depositary receipts shall have all the rights, privileges and preferences
to which they are entitled as Beneficial Owners of the Preferred Shares
represented by such depositary receipts. In lieu of fractional Preferred Shares
that are not integral multiples of one one-thousandth of a Preferred Share, the
Company shall pay to the registered holders of Right Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of one Preferred Share. For the purposes of
this Section 14(b), the current market value of a Preferred Share shall be the
closing price of a Preferred Share (as determined pursuant to the second
sentence of Section 11(d)(i) hereof) for the Trading Day immediately prior to
the date of such exercise.

          (c)  The Company shall not be required to issue fractions of Common
Shares or to distribute certificates which evidence fractional Common Shares. In
lieu of such fractional Common Shares, the Company shall pay to the registered
holder of the Right Certificates at the time such Rights are exercised as herein
provided an amount of cash equal to the same fraction of the current market
value of a whole Common Share. For the purpose of this Section 14(c), the
current market value of a Common Share (as defined pursuant to Section 11(d)(i)
hereof) for the Trading Day immediately prior to the date of such exercise.

          (d)  The holder of a Right by the acceptance of the Right expressly
waives such holder's right to receive any fractional Rights or any fractional
shares upon exercise of a Right (except as expressly provided above).

     Section 15. Rights of Action. All rights of action in respect of this
                 ----------------
Rights Agreement, except the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Right Certificate (or, prior to
the Distribution Date, of the Common Shares), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Common Shares), may, in such holder's own behalf and
for such holder's own benefit, 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 exercise the Rights evidenced by such Right

                                      18

Certificate in the manner provided in such Right Certificate and in this Rights
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 Rights 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 Rights Agreement.

     Section 16.    Agreement of Right Holders. Every holder of a Right, by
                    --------------------------
accepting the same, consents and agrees with the Company and the Rights Agent
and with every other holder of a Right that:

             (a)    prior to the Distribution Date, the Rights will be
transferable only in connection with the transfer of the Common Shares;

             (b)    after the Distribution Date, the Right Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the principal office of the Rights Agent, duly endorsed or accompanied by a
proper instrument of transfer; and

             (c)    the Company and the Rights Agent may deem and treat the
Person in whose name the Right Certificate (or, prior to the Distribution Date,
the associated Common Shares certificate) is registered as the absolute owner
thereof and of the Rights evidenced thereby (notwithstanding any notations of
ownership or writing on the Right Certificate or the associated Common Shares
certificate made by anyone other than the Company or the Rights Agent) for all
purposes whatsoever, and neither the Company nor the Rights Agent shall be
affected by any notice to the contrary.

     Section 17.    Right Certificate Holder Not Deemed a Stockholder. No
                    -------------------------------------------------
holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the Preferred Shares or any
other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Right Certificate shall have been exercised in accordance with the
provisions hereof.

     Section 18.    Concerning the Rights Agent. (a)  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 Rights Agreement and the exercise and performance of its
duties hereunder. The Company also agrees to indemnify the Rights Agent for, and
to hold it harmless against, any loss,

                                      19
<PAGE>

liability or expense incurred without negligence, bad faith or willful
misconduct on the part of the Rights Agent, for anything done or omitted by the
Rights Agent in connection with the acceptance and administration of this Rights
Agreement, including the costs and expenses of defending against any claim of
liability in the premises.

             (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 Rights Agreement in reliance upon
any Right Certificate or certificate for the Preferred Shares or Common Shares
or 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, or otherwise upon the advice of counsel as set
forth in Section 20 hereof.

     Section 19.    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 shall be a party, or any corporation succeeding to the stock
transfer or corporate trust powers of the Rights Agent or any successor Rights
Agent, shall be the successor to the Rights Agent under this Rights 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 21
hereof.  In case at the time such successor Rights Agent shall succeed to the
agency created by this Rights Agreement, any of the Right Certificates shall
have been countersigned but not delivered, any such successor Rights Agent may
adopt the countersignature of the predecessor Rights Agent and deliver such
Right Certificates so countersigned; and, in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor Rights Agent; and in all such cases such
Right Certificates shall have the full force provided in the Right Certificates
and in this Rights Agreement.

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

     Section 20.    Duties of Rights Agent. The Rights Agent undertakes the
                    ----------------------
duties and obligations imposed by this Rights Agreement upon the following terms
and

                                      20
<PAGE>

conditions, by all of which the Company and the holders of Right 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 opinion of such counsel shall 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 opinion.

             (b)    Whenever in the performance of its duties under this Rights
Agreement the Rights Agent shall deem 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 any one of the Chairman of the Board, the
Chief Executive Officer, the President, any Vice President, the Treasurer or the
Secretary of the Company and delivered to the Rights Agent; and such certificate
shall be full authorization to the Rights Agent for any action taken or suffered
in good faith by it under the provisions of this Rights Agreement in reliance
upon such certificate.

             (c)    The Rights Agent shall be liable hereunder to the Company
and any other Person only for its own negligence, bad faith or willful
misconduct.

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

             (e)    The Rights Agent shall not be under any responsibility in
respect of the validity of this Rights Agreement or the execution and delivery
hereof (except the due execution hereof by the Rights Agent) or in respect of
the validity or execution of any Right Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Rights Agreement or in any Right
Certificate; nor shall it be responsible for any change in the exercisability of
the Rights (including the Rights becoming void pursuant to Section 11(a)(ii)
hereof) or any adjustment in the terms of the Rights (including the manner,
method or amount thereof) provided for in Section 3, 11, 13, 23 or 24, or the
ascertaining of the existence of facts that would require any such change or
adjustment (except with respect to the exercise of Rights evidenced by Right
Certificates after actual notice that such change or adjustment is required);
nor shall it by any act hereunder be deemed to make any representation or
warranty as to the authorization or reservation of any Preferred Shares to be
issued pursuant to this Rights Agreement or any Right Certificate or as to
whether any Preferred Shares will, when issued, be validly authorized and
issued, fully paid and nonassessable.

                                      21
<PAGE>

             (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 Rights Agreement.

             (g)    The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
one of the Chairman of the Board, the Chief Executive Officer, the President,
any Vice President, the Secretary or the Treasurer of the Company, and to apply
to such officers 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 officer or for any delay in acting
while waiting for those instructions.

             (h)    The Rights Agent and any stockholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the 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 Rights 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 shall 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 reasonable care was exercised in the selection
and continued employment thereof.

     Section 21.    Change of Rights Agent. The Rights Agent or any successor
                    ----------------------
Rights Agent may resign and be discharged from its duties under this Rights
Agreement upon 30-days' notice in writing mailed to the Company and to each
transfer agent of the Common Shares or Preferred Shares by registered or
certified mail, and to the holders of the Right Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
30-days' notice in writing, mailed to the Rights Agent or successor Rights
Agent, as the case may be, and to each transfer agent of the Common Shares or
Preferred Shares by registered or certified mail, and to the holders of the
Right Certificates by first-class mail. If the Rights Agent shall resign or be
removed or shall otherwise become incapable of acting, the Company shall appoint
a successor to the Rights Agent. If the Company shall fail to make such
appointment within a period of 30 days after giving notice of 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 a Right Certificate
(who or which shall, with such notice, submit such holder's Right Certificate
for inspection by the Company), then the registered holder of any Right
Certificate 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

                                      22
<PAGE>

such a court, shall be a corporation organized and doing business under the laws
of the United States or of the State of New York (or of any other state of the
United States so long as such corporation is authorized to do business as a
banking institution in the State of New York, in good standing, having an office
in the State of New York, which is authorized under such laws to exercise
corporate trust or stock transfer powers 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
million. After appointment, the successor Rights Agent shall 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 shall file notice thereof in writing
with the predecessor Rights Agent and each transfer agent of the Common Shares
or Preferred Shares, and mail a notice thereof in writing to the registered
holders of the Right Certificates. Failure to give any notice provided for in
this Section 21, 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.

     Section 22.    Issuance of New Right Certificates. Notwithstanding any of
                    ----------------------------------
the provisions of this Rights Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Right Certificates evidencing Rights in
such form as may be approved by the Board of Directors of the Company to reflect
any adjustment or change in the Purchase Price and the number or kind or class
of shares or other securities or property purchasable under the Right
Certificates made in accordance with the provisions of this Rights Agreement.

     Section 23.    Redemption. (a) The Board of Directors of the Company may,
                    ----------
at its option, at any time prior to the Distribution Date, redeem all but not
less than all the then outstanding Rights at a redemption price of $.01 per
Right, appropriately adjusted to reflect any stock split, stock combination,
stock dividend or similar transaction occurring after the date hereof (such
redemption price being hereinafter referred to as the "Redemption Price"). The
redemption of the Rights by the Board of Directors of the Company may be made
effective at such time, on such basis and with such conditions as the Board of
Directors of the Company, in its sole discretion, may establish. Notwithstanding
anything to the contrary in this Agreement, the Rights shall not be exercisable
after the first occurrence of the event described in Section 11(a)(ii) until
such time as the Company's right of redemption hereunder has expired. The
Company may, at its option, pay the Redemption Price in cash, Common Shares
(based on the current market price at the time of redemption) or any other form
of consideration deemed appropriate by the Board of Directors.

             (b)    Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights pursuant to paragraph (a) of this
Section 23, and without any further action and without any notice, the right to
exercise the Rights

                                      23
<PAGE>

will terminate and the only right thereafter of the holders of Rights shall be
to receive the Redemption Price. The Company shall promptly give public notice
of any such redemption; provided, however, that the failure to give, or any
                        --------  -------
defect in, any such notice shall not affect the validity of such redemption.
Within 10 days after such action of the Board of Directors of the Company
ordering the redemption of the Rights, the Company shall mail a notice of
redemption to all the holders of the then outstanding Rights at their last
addresses as they appear upon the registry books of the Rights Agent or, prior
to the Distribution Date, on the registry books of the transfer agent for the
Common Shares. Any notice which is mailed in the manner herein provided shall be
deemed given, whether or not the holder receives the notice. Each such notice of
redemption will state the method by which the payment of the Redemption Price
will be made. Neither the Company nor any of its Affiliates or Associates may
redeem, acquire or purchase for value any Rights at any time in any manner other
than that specifically set forth in this Section 23 or in Section 24 hereof, and
other than in connection with the purchase of Common Shares prior to the
Distribution Date.

     Section 24.    Exchange. (a) The Board of Directors of the Company may, at
                    --------
its option, at any time after any Person becomes an Acquiring Person, exchange
all or part of the then outstanding and exercisable Rights (which shall not
include Rights that have become void pursuant to the provisions of Section
11(a)(ii) hereof) for Common Shares at an exchange ratio of one Common Share per
Right, appropriately adjusted to reflect any adjustment in the number of Rights
pursuant to Section 11(i) (such exchange ratio being hereinafter referred to as
the "Exchange Ratio"). Notwithstanding the foregoing, the Board of Directors of
the Company shall not be empowered to effect such exchange at any time after any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or any such Subsidiary, or any entity holding Common
Shares for or pursuant to the terms of any such plan), together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or
more of the Common Shares then outstanding.

             (b)    Immediately upon the action of the Board of Directors of the
Company ordering the exchange of any Rights pursuant to paragraph (a) of this
Section 24 and without any further action and without any notice, the right to
exercise such Rights shall terminate and the only right thereafter of a holder
of such Rights shall be to receive that number of Common Shares equal to the
number of such Rights held by such holder multiplied by the Exchange Ratio. The
Company shall promptly give public notice of any such exchange; provided,
however, that the failure to give, or any defect in, such notice shall not
affect the validity of such exchange. The Company promptly shall mail a notice
of any such exchange to all of the holders of such Rights at their last
addresses as they appear upon the registry books of the Rights Agent. Any notice
which is mailed in the manner herein provided shall be deemed given, whether or
not the holder receives the notice. Each such notice of exchange will state the
method by which the exchange of the Common Shares for Rights will be effected
and, in the event of any partial exchange, the number of Rights which will be
exchanged. Any partial exchange shall be effected pro rata based on the number
of Rights (other than Rights which have

                                      24
<PAGE>

become void pursuant to the provisions of Section 11(a)(ii) hereof) held by each
holder of Rights.

             (c)    In the event that there shall not be sufficient Common
Shares issued but not outstanding or authorized but unissued to permit any
exchange of Rights as contemplated in accordance with this Section 24, the
Company shall take all such action as may be necessary to authorize additional
Common Shares for issuance upon exchange of the Rights. In the event the Company
shall, after good faith effort, be unable to take all such action as may be
necessary to authorize such additional Common Shares, the Company shall
substitute, for each Common Share that would otherwise be issuable upon exchange
of a Right, a number of Preferred Shares or fraction thereof (or a security with
substantially similar rights, privileges, preferences, voting power and economic
rights) such that the current per share market price of one Preferred Share (or
other such security) multiplied by such number or fraction is equal to the
current per share market price of one Common Share as of the date of issuance of
such Preferred Shares or fraction thereof (or other such security).

             (d)    The Company shall not be required to issue fractions of
Common Shares or to distribute certificates which evidence fractional Common
Shares. In lieu of such fractional Common Shares, the Company shall pay to the
registered holders of the Right Certificates with regard to which such
fractional Common Shares would otherwise be issuable an amount in cash equal to
the same fraction of the current market value of a whole Common Share. For the
purposes of this paragraph (d), the current market value of a whole Common Share
shall be the closing price of a Common Share (as determined pursuant to the
second sentence of Section 11(d)(i) hereof) for the Trading Day immediately
prior to the date of exchange pursuant to this Section 24.

     Section 25.    Notice of Certain Events. (a) In case the Company, at any
                    ------------------------
time after the Distribution Date, shall propose (i) to pay any dividend payable
in stock of any class to the holders of its Preferred Shares or to make any
other distribution to the holders of its Preferred Shares (other than a regular
quarterly cash dividend), (ii) to offer to the holders of its Preferred Shares
rights or warrants to subscribe for or to purchase any additional Preferred
Shares or shares of stock of any class or any other securities, rights or
options, (iii) to effect any reclassification of its Preferred Shares (other
than a reclassification involving only the subdivision of outstanding Preferred
Shares), (iv) to effect any consolidation or merger into or with, or to effect
any sale or other transfer (or to permit one or more of its Subsidiaries to
effect any sale or other transfer), in one or more transactions, of 50% or more
of the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to, any other Person, (v) to effect the liquidation, dissolution or
winding up of the Company, or (vi) to declare or pay any dividend on the Common
Shares payable in Common Shares or to effect a subdivision, combination or
consolidation of the Common Shares (by reclassification or otherwise than by
payment of dividends in Common Shares), then, in each such case, the Company
shall give to each holder of a Right Certificate, in accordance with Section 26
hereof, a notice of such proposed action, which shall specify the record date
for the purposes of such stock dividend, or distribution of rights or warrants,
or the date on which such reclassification,

                                      25
<PAGE>

consolidation, merger, sale, transfer, liquidation, dissolution, or winding up
is to take place and the date of participation therein by the holders of the
Common Shares and/or Preferred Shares, if any such date is to be fixed, and such
notice shall be so given in the case of any action covered by clause (i) or (ii)
above at least 10 days prior to the record date for determining holders of the
Preferred Shares for purposes of such action, and in the case of any such other
action, at least 10 days prior to the date of the taking of such proposed action
or the date of participation therein by the holders of the Common Shares and/or
Preferred Shares, whichever shall be the earlier.

             (b)    In case the event set forth in Section 11(a)(ii) hereof
shall occur, then the Company shall as soon as practicable thereafter give to
each holder of a Right Certificate, in accordance with Section 26 hereof, a
notice of the occurrence of such event, which notice shall describe such event
and the consequences of such event to holders of Rights under Section 11(a)(ii)
hereof.

     Section 26.    Notices. Notices or demands authorized by this Rights
                    -------

                    --------------------------
Company may from time to time supplement or amend this Rights Agreement without
the approval of any holders of Right Certificates in order to cure any
ambiguity, to correct or supplement any provision contained herein which may be
defective or inconsistent with any other provisions herein, or to make any other
provisions with

                                      26
<PAGE>

respect to the Rights which the Board of Directors of the Company may deem
necessary or desirable, any such supplement or amendment to be evidenced by a
writing signed by the Company and the Rights Agent, provided, however, after the
Distribution Date, this Rights Agreement shall not be amended in any manner
which would adversely affect the interests of the holders of Rights (other than
an Acquiring Person or Affiliate or Associate thereof).

     Section 28.    Successors. All the covenants and provisions of this Rights
                    ----------
Agreement by or for the benefit of the Company or the Rights Agent shall bind
and inure to the benefit of their respective successors and assigns hereunder.

     Section 29.    Benefits of this Rights Agreement. Nothing in this Rights
                    ---------------------------------
Agreement shall be construed to give to any Person, other than the Company, the
Rights Agent and the registered holders of the Right Certificates (and, prior to
the Distribution Date, the Common Shares) any legal or equitable right, remedy
or claim under this Rights Agreement; but this Rights Agreement shall be for the
sole and exclusive benefit of the Company, the Rights Agent and the registered
holders of the Right Certificates (and, prior to the Distribution Date, the
Common Shares).

     Section 30.    Severability. If any term, provision, covenant or
                    ------------
restriction of this Rights Agreement is held by a court of competent
jurisdiction or other authority to be invalid, void or unenforceable, the

                         SUMMARY OF RIGHTS TO PURCHASE
                               PREFERRED SHARES

          On May 11, 1999, the Board of Directors of LifePoint Hospitals, Inc.
(the "Company") authorized and declared the issuance of one preferred share
purchase right (a "Right") for each share of common stock, par value $.01 per
share (the "Common Shares"), of the Company to be issued in the distribution of
Common Shares effective May 11, 1999 (the "Record Date"), as such distribution
is described in the Registration Statement on Form 10 (File No. 0-29818) dated
April 27, 1999 (the "Spin-Off").  Each Right entitles the registered holder to
purchase from the Company one one-thousandth of a share of Series A Junior
Participating Preferred Stock of the Company, par value $.01 per share (the
"Preferred Shares"), at a price of $35 per one one-thousandth of a Preferred
Share (the "Purchase Price"), subject to adjustment.  The description and terms
of the Rights are set forth in a Rights Agreement (the "Rights Agreement")
between the Company and National City Bank as Rights Agent (the "Rights Agent").

Distribution Date; Exercisability
---------------------------------

          Initially, the Rights will be attached to all Common Share
certificates and no separate Rights certificates will be issued.  Separate
certificates evidencing the Rights ("Right Certificates") will be mailed to
holders of record of the Common Shares as of the close of business on the
earlier to occur of the tenth day (or such other date as the Board of Directors
of the Company shall determine) after (i) a public announcement that a person or
group of affiliated or associated persons (an "Acquiring Person") has acquired
beneficial ownership of 15% or more of the outstanding Common Shares or (ii) the
commencement of, or announcement of an intention to make, a tender offer or
exchange offer the consummation of which would result in the beneficial
ownership by a person or group of 15% or more of the outstanding Common Shares
(the earlier of such dates being the "Distribution Date").

          The Rights Agreement provides that, until the Distribution Date (or
earlier redemption or expiration of the Rights), (i) the Rights will be
transferred with and only with the Common Shares, (ii) 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 and (iii) the surrender for transfer of any certificates for Common
Shares outstanding as of the Record Date will also constitute the transfer of
the Rights associated with the Common Shares represented by such certificate.

          The Rights are not exercisable until the Distribution Date.  The
Rights will expire on May 7, 2009 (the "Expiration Date"), unless the Expiration
Date is extended or unless the Rights are earlier redeemed or exchanged by the
Company, in each case, as described below.

                                      B-1
<PAGE>

Flip-In
-------

     If a person or group becomes an Acquiring Person, each holder of a Right
will thereafter have the right to receive, upon exercise, Common Shares (or, in
certain circumstances, Preferred Shares or other similar securities of the
Company) having a value equal to two times the exercise price of the Right.
Notwithstanding any of the foregoing, following the existence of an Acquiring
Person, all Rights that are, or (under certain circumstances specified in the
Rights Agreement) were, beneficially owned by any Acquiring Person will be null
and void.

     For example, at an exercise price of $50.00 per Right, each Right not owned
by an Acquiring Person following an event set forth in the preceding paragraph
would entitle its holder to purchase $100.00 worth of Common Shares (or other
consideration, as noted above) for $50.00.  Assuming a value of $25.00 per
Common Share at such time, the holder of each valid Right would be entitled to
purchase four Common Shares for $50.00.

Flip-Over
---------

          In the event that the Company is acquired in a merger or other
business combination transaction or 50% or more of its consolidated assets or
earning power are sold after a person or group has become an Acquiring Person,
proper provision will be made so that each holder of a Right will thereafter
have the right to receive, upon the exercise thereof at the then current
exercise price of the Right, that number of shares of common stock of the
acquiring company which at the time of such transaction will have a market value
of two times the exercise price of the Right.  In the event that any person or
group becomes an Acquiring Person, proper provision shall be made so that each
holder of a Right, other than Rights beneficially owned by the Acquiring Person
(which will thereafter be void), will thereafter have the right to receive upon
exercise that number of Common Shares having a market value of two times the
exercise price of the Right.

Exchange
--------

          At any time after any person or group becomes an Acquiring Person and
prior to the acquisition by such person or group of 50% or more of the
outstanding Common Shares, the Board of Directors of the Company may exchange
the Rights (other than Rights owned by such person or group which will have
become void), in whole or in part, at an exchange ratio of one Common Share, or
one one-thousandth of a Preferred Share (or of a share of a class or series of
the Company's preferred stock having equivalent rights, preferences and
privileges), per Right (subject to adjustment).

Redemption
----------

          At any time prior to the Distribution Date, the Board of Directors of
the Company may redeem the Rights, in whole but not in part, at a price of $.01
per Right (the "Redemption Price"). The redemption of the Rights may be made
effective at such time on such basis with such conditions as the Board of
Directors, in its sole discretion, may establish. Immediately upon any
redemption of the Rights, the right to exercise the Rights will terminate and
the only right of the holders of Rights will be to receive the

                                      B-2
<PAGE>

Redemption Price. The Rights are not exercisable after the first occurrence of
"flip-in" event (described above) until such time as the Company's right of
redemption has expired.

Amendment
---------

          The terms of the Rights may be amended by the Board of Directors of
the Company without the consent of the holders of the Rights, except that after
the Distribution Date no such amendment may adversely affect the interests of
the holders of the Rights (other than the Acquiring Person).

Adjustment
----------

          The number of outstanding Rights and the number of one one-thousandths
of a Preferred Share issuable upon exercise of each Right are subject to
adjustment under certain circumstances.

Preferred Stock
---------------

          Because of the nature of the Preferred Shares' dividend, liquidation
and voting rights, the value of the one one-thousandth interest in a Preferred
Share purchasable upon exercise of each Right should approximate the value of
one Common Share.

Rights of Holders
-----------------

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

Further Information
-------------------

          A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to a Registration Statement on Form 10 dated
April 27, 1999.  A copy of the Rights Agreement is available free of charge from
the Company.  This summary description of the Rights does not purport to be
complete and is qualified in its entirety by reference to the Rights Agreement,
