Item 1. Description of Registrant's Securities to be Registered

         On November 19, 1999 our board of directors approved the adoption of
a rights agreement (commonly known as a "poison pill"). The discussion below
describes the rights agreement entered into between us and SunTrust Bank,
Atlanta, as rights agent, dated as of December 2, 1999, as amended and restated
as of December 13, 1999, (the "Rights Agreement") but is not complete, so you
should read it together with the Rights Agreement. The Rights Agreement is
attached hereto as Exhibit 2.

ISSUANCE OF RIGHTS

         Under the Rights Agreement, we will issue the following stock purchase
rights:

         -        For each share of our Class A Common Stock, no par value per
                  share, outstanding on December 16, 1999 we will issue one
                  right; and

         -        For each share of our Class B Common Stock, no par value per
                  share, outstanding on December 16, 1999 we will issue one
                  right.

         In addition, one right will automatically attach to each share of
common stock that we issue between December 16, 1999 and the time that the
rights become exercisable. When exercised, each right will entitle its holder to
purchase from us one one-hundredth of a share (a "unit") of our Series C Junior
Participating Preferred Stock, no par value per share (the "Series C Preferred
Stock"), at an exercise price of $48.00 per unit, subject to adjustment.

INITIAL EXERCISE OF RIGHTS

         The rights initially will not be exercisable. Instead, the rights will
be attached to and trade with all shares of our common stock outstanding as of,
and issued after, December 16, 1999. The rights will separate from the common
stock and will become exercisable upon the earlier of the following events (the
"distribution date"):

         -        The close of business on the tenth business day (or later day
                  as our board of directors may determine) following the first
                  public announcement that a person or group of affiliated or
                  associated persons (other than certain "exempt persons") has
                  acquired beneficial ownership of 15% or more of our shares of
                  Class A Common Stock then outstanding or 15% or more of our
                  shares of Class B Common Stock then outstanding (an "Acquiring
                  Person"); or

         -        The close of business on the tenth business day (or some later
                  day as our board of directors may determine) following the
                  commencement of a tender offer or exchange offer that could
                  result in a person or group becoming the beneficial owner of
                  15% or more of our shares of Class A Common Stock then
                  outstanding or 15% or more of our shares of Class B Common
                  Stock then outstanding.


                                       2
<PAGE>   3

         The rights will expire at the close of business on December 2, 2009
unless we redeem or exchange the rights as described below.

         The exempt persons who are not considered Acquiring Persons include (1)
Wasatch Advisors, Inc. and (2) Waddell & Reed Investment Management Company,
Waddell & Reed, Inc., Waddell & Reed Financial, Inc., and Waddell & Reed
Financial Services, Inc. (collectively the "Waddell & Reed Companies") Should
Wasatch become the beneficial owner of an additional share of our Class A Common
Stock or an additional share of our Class B Common Stock after the date of the
Rights Agreement it will no longer be an exempt person provided that it then
falls within the definition of Acquiring Person. Should any of the Waddell &
Reed Companies acquire an additional share of our Class B Common Stock after the
date of the Rights Agreement or such additional shares of Class A Common Stock
as would result in any of them becoming the beneficial owner of 15% or more of
our Class A Common Stock then outstanding each of the Waddell & Reed Companies
will no longer be an exempt person provided that it then falls within the
definition of Acquiring Person.

EVIDENCE OF RIGHTS

         Until the rights become exercisable:

         -        The rights will be evidenced by and transferred with our
                  common stock certificates; and

         -        New common stock certificates issued after December 16, 1999
                  will contain a notation incorporating the Rights Agreement by
                  reference; and

         -        Any surrender for transfer of any certificates for our common
                  stock will also constitute the transfer of the rights
                  associated with the common stock represented by those
                  certificates.

         As soon as practicable after the rights become exercisable, we will
mail out rights certificates to the holders of our common stock who are eligible
to receive rights. After we mail them out, the separate rights certificates
alone will represent the rights.

EXERCISE AFTER SOMEONE BECOMES AN ACQUIRING PERSON

         After public announcement that a person has become an Acquiring Person,
each holder of a right will have the right to receive upon exercise of the
rights that number of shares of Class A Common Stock (or in our board's
discretion, some other consideration), having a value of two times the then
current purchase price of the right. However, this will not apply to an
Acquiring Person or their associates or affiliates, whose rights will have
become null and void.

         Under certain circumstances, each holder of a right will have the right
to receive upon exercise of the rights common stock of a company acquiring us
having a value equal to two times the then current purchase price of the right.
Each holder of a right will receive the right contemplated


                                       3
<PAGE>   4



by this paragraph in the event that, at any time on or after the date it is
publicly announced that a person has become an Acquiring Person:

         -        We consolidate with, or merge with and into, any other person,
                  and we are not the continuing or surviving corporation; or

         -        Any person consolidates with us, or merges with us and we are
                  the continuing or surviving corporation of that merger and, in
                  connection with that merger, all or part of the shares of our
                  common stock are changed into or exchanged for stock or other
                  securities of any other person or cash or any other property;
                  or

         -        We sell or transfer 50% or more of our assets or earning
                  power.

         The holder of a right will continue to have this right whether or not
that holder has previously exercised its right in accordance with the first
paragraph of this subsection. Rights that are or were beneficially owned by an
Acquiring Person may (under certain circumstances specified in the Rights
Agreement) become null and void.

EXCHANGE

         At any time after a person becomes an Acquiring Person, we may exchange
all or part of the outstanding and exercisable rights for shares of our Class A
Common Stock at an exchange ratio specified in the Rights Agreement. We
generally may not make an exchange after any person becomes the beneficial owner
of 50% or more of either our Class A Common Stock or Class B Common Stock.

ADJUSTMENT

         The purchase price and the number of shares of Class A Common Stock or
other securities or property issuable upon exercise of the rights is subject to
adjustment from time to time to prevent certain types of dilution. With certain
exceptions, the purchase price of the rights will not be adjusted until
cumulative adjustments amount to at least 1% of the purchase price. We are not
obligated to issue fractional units or shares of Class A Common Stock. If we
decide not to issue fractional units or shares of Class A Common Stock, we will
make an adjustment in cash based on the fair market value of a unit or share on
the last trading date prior to the date of exercise.

REDEMPTION

         We may redeem the rights in whole, but not in part, at a price of
$0.001 per right (payable in cash, preferred stock or other consideration that
we deem appropriate). However, we may only redeem the rights until the earlier
of ten days after someone becomes an Acquiring Person or December 2, 2009.


                                       4
<PAGE>   5



         Once redeemed, the rights will terminate immediately and the only right
of the holders of the rights will be to receive the redemption price.

AMENDMENT OF RIGHTS AGREEMENT

         We may amend the Rights Agreement without the approval of the holders
of our common stock until the distribution date. After the distribution date and
without the approval of the rights holders, we will only be able to amend the
Rights Agreement in order to cure any ambiguity, defect or inconsistency, to
shorten or lengthen any time period, or to make changes that do not adversely
affect the interests of rights holders excluding the interests of an Acquiring
Person or their associates or affiliates. We may only amend the time period
governing redemption of the rights if the rights are presently redeemable.

OTHER

         Until a right is exercised, the holder will have no rights as a
shareholder of ours as a result of the rights. This means, for example, that
until it is exercised, a right will not entitle its holder to vote or receive
dividends like one of our shareholders. The distribution of the rights will not
be taxable to shareholders or to us. However, shareholders may, depending upon
the circumstances, recognize taxable income in the event that the rights become
exercisable for units of Series C Preferred Stock, shares of Class A Common
Stock, other consideration or for common stock of an acquiring company.

         The discussion above describes the rights and the Rights Agreement but
is not complete, so you should read it together with the Rights Agreement. The
Rights Agreement is filed as an exhibit hereto. We have attached to the Rights
Agreement as Exhibits A, B, and C respectively, the form of rights certificate,
the summary of rights and the form of articles of amendment to our amended and
restated charter.

         As of December 2, 1999, 9,746,983 shares of our Class A Common Stock
were issued and outstanding and 4,787,131 shares of our Class B Common Stock
were issued and outstanding. Each share of our common stock outstanding on
December 16, 1999 will receive one right. As long as the rights are attached to
our common stock, we will issue one right for each share of our common stock
issued between the December 16, 1999 and the distribution date. A total of
398,000 shares of Series C Preferred Stock have been reserved for issuance upon
exercise of the rights, subject to adjustment.

         The units of Series C Preferred Stock that may be acquired upon
exercise of the rights will be nonredeemable and subordinate to any other shares
of preferred stock that may be issued by the Company.

         Each unit of Series C Preferred Stock will be entitled to receive,
when, as and if declared, dividends at the same rate as dividends are paid with
respect to the Class A Common Stock.


                                       5
<PAGE>   6



         In the event of liquidation, the holder of a unit of Series C Preferred
Stock will be entitled to share in any assets remaining ratably with the holders
of the Class A Common Stock.

         Each unit of Series C Preferred Stock issued to a holder of our common
stock will have one vote, voting together with our common stock.

         In the event of any merger, share exchange or other transaction in
which shares of our common stock are exchanged, each unit of Series C Preferred
Stock will be entitled to receive the per share amount paid in respect of each
share of Class A Common Stock.

         The rights of holders of the Series C Preferred Stock to dividends,
liquidation and voting, and in the event of mergers and share exchanges, are
protected by customary anti-dilution provisions.

         Because of the nature of the Series C Preferred Stock's dividend,
liquidation and voting rights, the economic value of one unit of Series C
Preferred Stock that may be acquired upon the exercise of each right should
approximate the economic value of one share of Class A Common Stock.

         The rights may have certain anti-takeover effects. The rights will
cause substantial dilution to a person or group that attempts to acquire us on
terms not approved by a majority of our board of directors unless the offer is
conditioned on a substantial number of rights being acquired. However, the
rights should not interfere with any merger or other business combination
approved by our board of directors since the rights may be redeemed by us at
$0.001 per right at any time on or prior to the tenth day following the
announcement that someone has become an Acquiring Person. Thus, the rights are
intended to encourage persons who may seek to acquire control of us to initiate
such an acquisition through negotiations with our board of directors. However,
the effect of the rights may be to discourage a third party from making a
partial tender offer or otherwise attempting to obtain a substantial equity
position in the equity securities of, or seeking to obtain control of, us. To
the extent any potential acquirers are deterred by the rights, the rights may
have the effect of preserving incumbent management in office.

         The form of Rights Agreement between the Company and the rights agent
specifying the terms of the rights, which includes as Exhibit A the form of
rights certificate, is filed herewith as Exhibit 2. The foregoing description of
the rights does not purport to be complete and is qualified in its entirety by
reference to such Exhibit.

                     AMENDED AND RESTATED RIGHTS AGREEMENT

         AMENDED AND RESTATED RIGHTS AGREEMENT, dated this 13th day of December,
1999 (the "Agreement"), between AmSurg Corp., a Tennessee corporation (the
"Company"), and SunTrust Bank, Atlanta (the "Rights Agent").

         WHEREAS, on November 19, 1999 (the "Rights Dividend Declaration Date"),
the Board of Directors of the Company authorized and declared a distribution of
one Right for each share of Class A Common Stock, no par value per share, and
Class B Common Stock, no par value per share, of the Company (the Class A Common
Stock and the Class B Common Stock together, the "Company Common Stock")
outstanding at the Close of Business on December 16, 1999 (the "Record Date"),
subject to the execution of that certain Rights Agreement dated as of December
2, 1999 between the Company and the Rights Agent (the "Initial Rights
Agreement") and to certain other matters, and has authorized the issuance of one
Right (as such number may hereinafter be adjusted pursuant hereto) for each
share of Company Common Stock issued between the Record Date and the
Distribution Date, each Right initially representing the right to purchase upon
the terms and subject to the conditions hereinafter set forth one Unit of Series
C Junior Participating Preferred Stock (the "Right"or collectively, the
"Rights"); and

         WHEREAS, the Company, in accordance with Section 27 of the Initial
Rights Agreement, believes it to be desirable and in the best interests of the
Company and its shareholders that the Initial Rights Agreement be amended and
restated;

         NOW, THEREFORE, 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 Agreement, the
following terms have the meanings indicated:

         (a) "Acquiring Person" shall mean any Person (other than an Exempt
Person, the Company, any Subsidiary of the Company, any employee benefit plan
maintained by the Company or any of its Subsidiaries or any trustee or fiduciary
with respect to such plan acting in such capacity) which shall be the Beneficial
Owner of (i) 15% or more of the shares of Class A Common Stock then outstanding,
or (ii) 15% or more of the shares of Class B Common Stock then outstanding. If
the Board of Directors of the Company determines that a Person who would
otherwise be an "Acquiring Person," as defined pursuant to the foregoing
provisions of this paragraph (a), has become such inadvertently and in good
faith or without knowledge of the terms of this Agreement, and such Person
divests as promptly as practicable (but in no event more than thirty days
following notification of its status as an "Acquiring Person" or such shorter
period as may be determined by the Board of Directors) a sufficient number of
shares of either the Class A Common Stock or Class B Common Stock so that such
Person would no longer, as of the expiration of such divestiture period, be an
"Acquiring Person," as defined pursuant to the foregoing provisions of this
paragraph (a), then such Person shall not be deemed to be an "Acquiring Person"
for any purposes of this Agreement. Notwithstanding the foregoing, no Person
shall become an "Acquiring Person" as the result of an acquisition of Class A
Common Stock or Class B Common Stock by the Company which, by reducing the
number of shares of Class A Common Stock or Class B Common Stock outstanding,
increases the proportionate number of shares of Class A Common Stock or Class B
Common Stock beneficially owned by such Person (alone or together with all
affiliates and associates) to 15% or more of the shares of Class A Common Stock
then outstanding or 15% or more of the shares of Class B Common Stock then
outstanding; provided, however, that if a Person (together with its


<PAGE>   5



Affiliates and Associates) becomes the Beneficial Owner of 15% or more of the
shares of Class A Common Stock then outstanding by reason of share purchases by
the Company, and such Person (or an Affiliate or Associate) subsequently becomes
the Beneficial Owner of any additional share of Class A Common Stock, then such
Person shall be deemed to be an "Acquiring Person;" provided further that if a
Person (together with its Affiliates and Associates) becomes the Beneficial
Owner of 15% or more of the shares of Class B Common Stock then outstanding by
reason of share purchases by the Company, and such Person (or an Affiliate or
Associate) subsequently becomes the Beneficial Owner of any additional share of
Class B Common Stock, then such Person shall be deemed to be an "Acquiring
Person."

         (b) "Affiliate" and "Associate" shall have the respective meanings
ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as in
effect on the date hereof.

         (c) A Person shall be deemed the "Beneficial Owner" of, and shall be

Associates is considered to be a "beneficial owner" under Rule 13d-3 of the
General Rules and Regulations under the Exchange Act (the "Exchange Act
Regulations") as in effect on the date hereof; provided, however, that a Person
shall not be deemed the "Beneficial Owner" of, or to "beneficially own," any
security under this subparagraph (i) as a result of an agreement, arrangement or
understanding, to vote such security if such agreement, arrangement or
understanding (A) arises solely from a revocable proxy given in response to a
proxy or consent solicitation made pursuant to, and in accordance with, the
applicable provisions of the Exchange Act and the Exchange Act Regulations, and
(B) is not reportable by such Person on Schedule 13D under the Exchange Act (or
any comparable or successor report);

             (ii) which are beneficially owned, directly or indirectly, by any
other Person (or any Affiliate or Associate of such other Person) with which
such Person (or any of such Person's Affiliates or Associates) has any
agreement, arrangement or understanding (whether or not in writing), for the
purpose of acquiring, holding, voting (except pursuant to a revocable proxy as
described in the proviso to subparagraph (i) of this paragraph (c)) or disposing
of such securities; or

             (iii) which such Person or any of such Person's Affiliates or
Associates, directly or indirectly, has the right to acquire (whether such right
is exercisable immediately or only after the passage of time or upon the
satisfaction of conditions) pursuant to any agreement, arrangement or
understanding (whether or not in writing) or upon the exercise of conversion
rights, exchange rights, rights, warrants or options, or otherwise;

provided, however, that under this paragraph (c) a Person shall not be deemed
the "Beneficial Owner" of, or to "beneficially own," (A) securities tendered
pursuant to a tender or exchange offer made by such Person or any of such
Person's Affiliates or Associates until such tendered securities

                                        2

Common Stock from and after which time it shall be deemed to be an Acquiring

and provided further that the Waddell & Reed Companies shall not be deemed to be
Exempt Persons if after the date of this Agreement any of them becomes the
Beneficial Owner of an additional share of Class B Common Stock, or such

         Section 2. Appointment of Rights Agent. The Company hereby appoints the
Rights Agent to act as agent for the Company in accordance with the terms and
conditions hereof, and the Rights Agent hereby accepts such appointment. The
Company may from time to time appoint such Co-Rights Agents as it may deem
necessary or desirable.

         Section 3. Issue of Rights Certificates.

         (a) Until the earlier of (i) the Close of Business on the tenth day
after the Stock Acquisition Date, and (ii) the Close of Business on the tenth
day (or such later date as may be determined by the Board of Directors prior to
such time as any Person becomes an Acquiring Person) after the date that a
tender or exchange offer by any Person (other than the Company, any Subsidiary
of the Company, any employee benefit plan maintained by the Company or any of
its Subsidiaries or any trustee or fiduciary with respect to such plan acting in
such capacity) is first published or sent or given within the meaning of Rule
14d-4(a) of the Exchange Act Regulations, if upon consummation thereof such
Person would be the Beneficial Owner of either (A) 15% or more of the shares of
Class A Common Stock then outstanding or (B) 15% or more of the shares of Class
B Common Stock then outstanding (the earlier of (i) and (ii) above being the
"Distribution Date"), (x) the Rights will be evidenced (subject to the
provisions of paragraph (b) of this Section 3) by the certificates for shares of
Company Common Stock registered in the names of the holders of shares of Company
Common Stock as of and subsequent to the Record Date (which certificates for
shares of Company Common Stock shall be deemed also to be certificates for
Rights) and not by separate certificates, and (y) the Rights will be
transferable only in connection with the transfer of the underlying shares of
Company Common Stock (including a transfer to the Company). As soon as
practicable after the Distribution Date, the Rights Agent will send by
first-class, insured, postage prepaid mail, to each record holder of shares of
Company Common Stock as of the Close of Business on the Distribution Date, at
the address of such holder shown on the records of the Company, one or more
right certificates, in substantially the form of Exhibit A hereto (the "Rights
Certificates"), evidencing one Right for each share of Company Common Stock so
held, subject to adjustment as provided herein. In the event that an adjustment
in the number of Rights per share of Company Common Stock has been made pursuant
to Section 11(p) hereof, at the time of distribution of the Rights Certificates,
the Company shall make the necessary and appropriate rounding adjustments (in
accordance with Section 14(a) hereof) so that Rights Certificates representing
only whole numbers of Rights are distributed and cash is paid in lieu of any
fractional Rights. As of and after the Distribution Date, the Rights will be
evidenced solely by such Rights Certificates.

         (b) As promptly as practicable following the Record Date, the Company
will send a copy of a Summary of Rights to Purchase Preferred Stock, in a form
which may be appended to certificates that represent shares of Company Common
Stock in substantially the form attached hereto as Exhibit B (the "Summary of
Rights"), by first-class, postage prepaid mail, to each record holder of shares
of Company Common Stock as of the Close of Business on the Record Date, at the
address of such holder shown on the records of the Company.

         (c) Rights shall, without any further action, be issued in respect of
all shares of Company Common Stock which are outstanding on the Record Date and
which are issued after the Record Date but prior to the earlier of the
Distribution Date and the Expiration Date. Certificates representing such shares
of Company Common Stock issued after the Record Date shall bear the following
legend:

         "This certificate also evidences and entitles the holder hereof to
         certain Rights as set forth in the Rights Agreement between AmSurg
         Corp. (the "Company") and SunTrust Bank, Atlanta (the "Rights Agent")
         dated December 2, 1999, as amended and restated as of December 13, 1999
         (the "Rights Agreement"), the terms of which are hereby incorporated
         herein by reference and a copy of which is on file at the principal
         office of the stock transfer administration office of the Rights Agent.
         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, as in effect on the
         date of mailing, without charge promptly after receipt of a written
         request therefor. Under certain circumstances set forth in the Rights
         Agreement, Rights issued to, or held by, any Person who is, was or
         becomes an Acquiring Person or any Affiliate or Associate thereof (as
         such terms are defined in the Rights Agreement), whether currently held
         by or on behalf of such Person or by any subsequent holder, may become
         null and void."

With respect to certificates representing shares of Company Common Stock
(whether or not such certificates include the foregoing legend or have appended
to them the Summary of Rights), until the earlier of (i) the Distribution Date
or (ii) the Expiration Date, the Rights associated with the shares of Company
Common Stock represented by such certificates shall be evidenced by such
certificates alone and registered holders of the shares of Company Common Stock
shall also be the registered holders of the associated Rights, and the transfer
of any of such certificates shall also constitute the transfer of the Rights
associated with the shares of Company Common Stock represented by such
certificates.

         Section 4. Form of Rights Certificates.

         (a) The Rights Certificates (and the forms of election to purchase,
assignment and certificate to be printed on the reverse thereof) shall each be
substantially in the form set forth in 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 Agreement, or as may be required to comply with any
applicable law or any rule or regulation thereunder or with any rule or
regulation of any stock exchange on which the Rights may from time to time be
listed or to conform to usage. Subject to the provisions of Section 11 and
Section 22 hereof, the Rights Certificates, whenever distributed, shall be dated
as of the Record Date and on their face shall entitle the holders thereof to
purchase such number of Units of Preferred Stock as shall be set forth therein
at the price set forth therein, but the

                                        6


<PAGE>   10



amount and type of securities, cash or other assets that may be acquired upon
the exercise of each Right and the Purchase Price thereof shall be subject to
adjustment as provided herein.

         (b) Any Rights Certificate issued pursuant hereto that represents
Rights beneficially owned by: (i) an Acquiring Person or any Associate or
Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) which becomes a transferee after the
Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) which becomes a transferee prior to or
concurrently with the Acquiring Person becoming such and which receives such
Rights pursuant to either (A) a transfer (whether or not for consideration) from
the Acquiring Person (or any such Associate or Affiliate) to holders of equity
interests in such Acquiring Person (or such Associate or Affiliate) or to any
Person with whom such Acquiring Person (or such Associate or Affiliate) has any
continuing agreement, arrangement or understanding regarding either the
transferred Rights, shares of Company Common Stock of the Company or (B) a
transfer which the Board of Directors has determined to be part of a plan,
arrangement or understanding which has as a primary purpose or effect the
avoidance of Section 7(e) hereof shall, upon the written direction of the Board
of Directors, contain (to the extent feasible), the following legend:

         The Rights represented by this Rights Certificate are or were
         beneficially owned by a Person who was or became an Acquiring Person or
         an Affiliate or Associate of an Acquiring Person (as such terms are
         defined in the Rights Agreement). Accordingly, this Rights Certificate
         and the Rights represented hereby may become null and void in the
         circumstances specified in Section 7(e) of such Agreement.

         Section 5. Countersignature and Registration.

         (a) Rights Certificates shall be executed on behalf of the Company by
its Chairman of the Board, President or one of its Vice Presidents and shall be
attested by its Secretary or one of its Assistant Secretaries. The signature of
any of these officers on the Rights Certificates may be manual or facsimile.
Rights Certificates bearing the manual or facsimile signatures of the
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the countersignature of such Rights Certificates or
did not hold such offices at the date of such Rights Certificates. No Rights
Certificate shall be entitled to any benefit under this Agreement or be valid
for any purpose unless there appears on such Rights Certificate a
countersignature duly executed by the Rights Agent by manual signature of an
authorized officer, and such countersignature upon any Rights Certificate shall
be conclusive evidence, and the only evidence, that such Rights Certificate has
been duly countersigned as required hereunder.

         (b) Following the Distribution Date, the Rights Agent will keep or
cause to be kept, at its office designated for surrender of Rights Certificates
upon exercise or transfer, books for registration and transfer of the Rights
Certificates issued hereunder. Such books shall show the name

                                        7


<PAGE>   11



and address of each holder of the Rights Certificates, the number of Rights
evidenced on its face by each Rights Certificate and the date of each Rights
Certificate.

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

         (a) Subject to the provisions of Sections 4(b), 7(e) and 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 Expiration Date, any Rights Certificate or
Certificates may be transferred, split up, combined or exchanged for another
Rights Certificate or Certificates, entitling the registered holder to purchase
a like number of Units of Preferred Stock (or, following a Triggering Event,
other securities, cash or other assets, as the case may be) as the Rights
Certificate or Certificates surrendered then entitled such holder to purchase.
Any registered holder desiring to transfer, split up, combine or exchange any
Rights Certificate or Certificates shall make such request in writing delivered
to the Rights Agent, and shall surrender the Rights Certificate or Certificates
to be transferred, split up, combined or exchanged at the office of the Rights
Agent designated for such purpose. Neither the Rights Agent nor the Company
shall be obligated to take any action whatsoever with respect to the transfer of
any such surrendered Rights Certificate until the registered holder shall have
completed the certificate set forth in the form of assignment on the reverse
side of such Rights Certificate and shall have provided such additional evidence
of the identity of the Beneficial Owner (or former Beneficial Owner) of the
Rights represented by such Rights Certificate or Affiliates or Associates
thereof as the Company shall reasonably request; whereupon the Rights Agent
shall, subject to the provisions of Section 4(b), Section 7(e) and Section 14
hereof, countersign and deliver to the Person entitled thereto a Rights
Certificate or Rights Certificates, as the case may be, as so requested.

         (b) If a Rights Certificate shall be mutilated, lost, stolen or
destroyed, upon request by the registered holder of the Rights represented
thereby, there shall be issued, in exchange for and upon cancellation of the
mutilated Rights Certificate, or in substitution for the lost, stolen or
destroyed Rights Certificate, a new Rights Certificate, in substantially the
form of the prior Rights Certificate, of like tenor and representing the
equivalent number of Rights, but in the case of loss, theft or destruction, only
upon receipt of evidence satisfactory to the Company and the Rights Agent of
such loss, theft or destruction of such Rights Certificate and, if requested by
the Company or the Rights Agent, indemnity also satisfactory to it.

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

         (a) Prior to the earlier of (i) the Close of Business on the tenth
anniversary of the Initial Rights Agreement (the "Final Expiration Date"), or
(ii) the time at which the Rights are redeemed as provided in Section 23 hereof
(the earlier of (i) and (ii) being the "Expiration Date"), the registered holder
of any Rights Certificate may, subject to the provisions of Section 7(e) hereof,
exercise the Rights evidenced thereby (except as otherwise provided herein
including, without limitation, the restriction on exercisability set forth in
Section 23(a) hereof) in whole or in part at any time after the Distribution
Date upon surrender of the Rights Certificate, with the form of election to
purchase and the

                                        8


<PAGE>   12



certificate on the reverse side thereof duly executed, to the Rights Agent at
the office of the Rights Agent designated for such purpose, together with
payment of the aggregate Purchase Price (as hereinafter defined) for the number
of Units of Preferred Stock (or, following a Triggering Event, Class A Common
Stock, other securities, cash or other assets, as the case may be) for which
such surrendered Rights are then exercisable.

         (b) The purchase price for each one one-hundredth of a share (each such
one one-hundredth of a share being a "Unit") of Preferred Stock upon exercise of
the Rights shall be $48.00, subject to adjustment from time to time as provided
in Sections 11 and 13(a) hereof (such purchase price, as so adjusted, being the
"Purchase Price"), and shall be payable in accordance with paragraph (c) below.

         (c) As promptly as practicable following the occurrence of the
Distribution Date, the Company shall deposit with a corporation organized under
the laws of the United States or any State of the United States in good
standing, which is authorized under such laws to exercise corporate trust powers
and is subject to supervision or examination by federal or state authority
(which corporation may be a Subsidiary of the Company) (such institution being
the "Depositary Agent") certificates representing the shares of Preferred Stock
that may be acquired upon exercise of the Rights and shall cause such Depositary
Agent to enter into an agreement pursuant to which the Depositary Agent shall
issue receipts representing interests in the shares of Preferred Stock so
deposited. Upon receipt of a Rights Certificate representing exercisable Rights,
with the form of election to purchase and the certificate duly executed,
accompanied by payment, with respect to each Right so exercised, of the Purchase
Price for the Units of Preferred Stock (or, following a Triggering Event, other
securities, cash or other assets, as the case may be) to be purchased thereby as
set forth below and an amount equal to any applicable transfer tax or evidence
satisfactory to the Company of payment of such tax, the Rights Agent shall,
subject to Section 20(j) hereof, thereupon promptly (i) requisition from the
Depositary Agent depositary receipts representing such number of Units of
Preferred Stock as are to be purchased and the Company will direct the
Depositary Agent to comply with such request, (ii) requisition from the Company
the amount of cash, if any, to be paid in lieu of fractional shares in
accordance with Section 14 hereof, (iii) after receipt of such depositary
receipts, cause the same to be delivered to or upon the order of the registered
holder of such Rights Certificate, registered in such name or names as may be
designated by such holder, and (iv) after receipt thereof, deliver such cash, if
any, to or upon the order of the registered holder of such Rights Certificate.
In the event that the Company is obligated to issue Class A Common Stock, other
securities of the Company, pay cash and/or distribute other property pursuant to
Section 11(a) hereof, the Company will make all arrangements necessary so that
such Class A Common Stock, other securities, cash and/or other property are
available for distribution by the Rights Agent, if and when appropriate. The
payment of the Purchase Price (as such amount may be reduced pursuant to Section
11(a)(iii) hereof) may be made in cash or by certified or bank check or bank
draft payable to the order of the Company.

         (d) In case the registered holder of any Rights Certificate shall
exercise less than all the Rights evidenced thereby, a new Rights Certificate
evidencing the Rights remaining unexercised shall be issued by the Rights Agent
and delivered to, or upon the order of, the registered holder of

                                        9


<PAGE>   13



such Rights Certificate, registered in such name or names as may be designated
by such holder, subject to the provisions of Section 14 hereof.

         (e) Notwithstanding anything in this Agreement to the contrary, from
and after the first occurrence of a Section 11(a)(ii) Event, any Rights
beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of an
Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) which becomes a transferee after the Acquiring Person
becomes such, or (iii) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) which becomes a transferee prior to or concurrently with
the Acquiring Person becoming such and which receives such Rights pursuant to
either (A) a transfer (whether or not for consideration) from the Acquiring
Person (or any such Associate or Affiliate) to holders of equity interests in
such Acquiring Person (or any such Associate or Affiliate) or to any Person with
whom the Acquiring Person (or such Associate or Affiliate) has any continuing
agreement, arrangement or understanding regarding the transferred Rights, shares
of Company Common Stock or the Company or (B) a transfer which the Board of
Directors has determined to be part of a plan, arrangement or understanding
which has as a primary purpose or effect the avoidance of this Section 7(e),
shall be null and void without any further action, and no holder of such Rights
shall have any rights whatsoever with respect to such Rights, whether under any
provision of this Agreement or otherwise. The Company shall use all reasonable
efforts to ensure that the provisions of this Section 7(e) and Section 4(b)
hereof are complied with, but shall have no liability to any holder of Rights or
any other Person as a result of its failure to make any determination under this
Section 7(e) or such Section 4(b) with respect to an Acquiring Person or its
Affiliates, Associates or transferees.

         (f) Notwithstanding anything in this Agreement or any Rights
Certificate to the contrary, neither the Rights Agent nor the Company shall be
obligated to undertake any action with respect to a registered holder upon the
occurrence of any purported exercise by such registered holder unless such
registered holder shall have (i) completed and executed the certificate
following the form of election to purchase set forth on the reverse side of the
Rights Certificate surrendered for such exercise, and (ii) provided such
additional evidence of the identity of the Beneficial Owner (or former
Beneficial Owner) of the Rights represented by such Rights Certificate or
Affiliates or Associates thereof as the Company shall reasonably request.

         Section 8. Cancellation and Destruction of Rights Certificates. All
Rights Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or any of its
agents, be delivered to the Rights Agent for cancellation or in canceled form,
or, if surrendered to the Rights Agent, shall be canceled by it, and no Rights
Certificates shall be issued in lieu thereof except as expressly permitted by
this Agreement. The Company shall deliver to the Rights Agent for cancellation
and retirement, and the Rights Agent shall so cancel and retire, any Rights
Certificates acquired by the Company otherwise than upon the exercise thereof.
The Rights Agent shall deliver all canceled Rights Certificates to the Company,
or shall, at the written request of the Company, destroy such canceled Rights
Certificates, and in such case shall deliver a certificate of destruction
thereof to the Company.

         Section 9. Reservation and Availability of Capital Stock.

         (a) The Company shall (i) at all times prior to the Expiration Date
cause to be reserved and kept available out of its authorized and unissued
shares of preferred stock, the number of shares of Preferred Stock that, as
provided in this Agreement, will be sufficient to permit the exercise in full of
all outstanding Rights in accordance with Section 7 and (ii) at all times
following the occurrence of a Section 11(a)(ii) Event, shall so reserve and keep
available a sufficient number of any other securities that may be required to
permit the exercise in full of the Rights pursuant to this Agreement.

         (b) The Company shall use its best efforts (i) as soon as practicable
following the occurrence of a Section 11(a)(ii) Event and a determination by the
Company in accordance with Section 11(a)(iii) hereof of the consideration to be
delivered by the Company upon exercise of the Rights or, if so required by law,
as soon as practicable following the Distribution Date (such date being the
"Registration Date"), to file a registration statement on an appropriate form
under the Securities Act of 1933, as amended (the "Securities Act"), with
respect to the securities that may be acquired upon exercise of the Rights (the
"Registration Statement"), (ii) to cause the Registration Statement to become
effective as soon as practicable after such filing, (iii) to cause the
Registration Statement to continue to be effective (and to include a prospectus
complying with the requirements of the Securities Act) until the earlier of (A)
the date as of which the Rights are no longer exercisable for the securities
covered by the Registration Statement, and (B) the Expiration Date, and (iv) to
take as soon as practicable following the Registration Date such action as may
be required to ensure that any acquisition of securities upon exercise of the
Rights complies with any applicable state securities or "blue sky" laws.

         (c) The Company shall take such action as may be necessary to ensure
that all shares of Preferred Stock (and, following the occurrence of a
Triggering Event, any other securities that may be delivered upon exercise of
Rights) shall be, at the time of delivery of the certificates or depositary
receipts for such securities, duly and validly authorized and issued and fully
paid and nonassessable.

         (d) The Company shall pay any documentary, stamp or transfer tax
imposed in connection with the issuance or delivery of the Rights Certificates
or upon the exercise of Rights; provided, however, the Company shall not be
required to pay any such tax imposed in connection with the issuance or delivery
of Units of Preferred Stock, or any certificates or depositary receipts for such
Preferred Stock (or, following the occurrence of a Triggering Event, any other
securities, cash or assets, as the case may be) to any person other than the
registered holder of the Rights Certificates evidencing the Rights surrendered
for exercise. The Company shall not be required to issue or deliver any
certificates or depositary receipts for Units of Preferred Stock (or, following
the occurrence of a Triggering Event, any other securities, cash or assets, as
the case may be) to, or in a name other than that of, the registered holder upon
the exercise of any Rights until any such tax shall have been paid (any such tax
being payable by the holder of such Rights Certificate at the time of surrender)
or until it has been established to the Company's satisfaction that no such tax
is due.

         Section 10. Preferred Stock Record Date. Each person in whose name any
certificate for shares of Preferred Stock (or, following the occurrence of a
Triggering Event, other securities) is issued upon the exercise of Rights shall
for all purposes be deemed to have become the holder of record of the shares of
Preferred Stock (or, following the occurrence of a Triggering Event, other
securities) represented thereby on, and such certificate shall be dated, the
date upon which the Rights Certificate evidencing such Rights was duly
surrendered and payment of 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 Stock (or, following the occurrence
of a Triggering Event, other securities) transfer books of the Company are
closed, such Person shall be deemed to have become the record holder of such
securities on, and such certificate shall be dated, the next succeeding Business
Day on which the Preferred Stock (or, following the occurrence of a Triggering
Event, other securities) transfer books of the Company are open. Prior to the
exercise of the Rights evidenced thereby, the holder of a Rights Certificate
shall not be entitled to any rights of a shareholder of the Company with respect
to securities 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 and Kind of Shares or
Number of Rights. The Purchase Price, the number and kind of securities 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 Agreement (A) declare a dividend on the Preferred Stock payable in shares
of Preferred Stock, (B) subdivide the outstanding Preferred Stock, (C) combine
the outstanding Preferred Stock into a smaller number of shares, or (D) issue
any shares of its capital stock in a reclassification of the Preferred Stock
(including any such reclassification in connection with a share exchange or
merger in which the Company is the continuing or surviving corporation), except
as otherwise provided in this Section 11(a) and Section 7(e), 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 Preferred Stock or capital stock, as the case may be, issuable
on such date upon exercise of the Rights, shall be proportionately adjusted so
that the holder of any Right exercised after such time shall be entitled to
receive, upon payment of the Purchase Price then in effect, the aggregate number
and kind of shares of Preferred Stock or capital stock, as the case may be,
which, if such Right had been exercised immediately prior to such date, such
holder would have owned upon such exercise and been entitled to receive by
virtue of such dividend, subdivision, combination or reclassification. If an
event occurs which would require an adjustment under both this Section 11(a)(i)
and Section 11(a)(ii) hereof, the adjustment provided for in this Section
11(a)(i) shall be in addition to, and shall be made prior to, any adjustment
required pursuant to Section 11(a)(ii) hereof.

                                       12


<PAGE>   16



                  (ii) Subject to Section 24 of this Agreement, in the event
that any Person shall become an Acquiring Person, other than pursuant to any
transaction set forth in Section 13(a) hereof, then, promptly following the
occurrence of such event (a "Section 11(a)(ii) Event") (except as provided below
and in Section 7(e) hereof) each such holder shall have the right to receive,
upon exercise thereof at a price equal to the then current Purchase Price in
accordance with the terms of this Agreement, in lieu of the number of Units of
Preferred Stock for which a Right was exercisable immediately prior to the first
occurrence of a Section 11(a)(ii) Event, such number of shares of Class A Common
Stock as shall equal the result obtained by (x) multiplying the then current
Purchase Price by the then number of Units of Preferred Stock for which a Right
was exercisable immediately prior to the first occurrence of a Section 11(a)(ii)
Event (such product thereafter being, for all purposes of this Agreement other
than Section 13 hereof, the "Purchase Price"), and (y) dividing that product by
50% of the then current market price (determined pursuant to Section 11(d)
hereof) per share of Class A Common Stock on the date of such first occurrence
(such shares or number of shares being the "Adjustment Shares").

                  (iii) In the event that the number of shares of Class A Common
Stock which are authorized by the Company's charter but not outstanding or
reserved for issuance for purposes other than upon exercise of the Rights are
not sufficient to permit the exercise in full of the Rights in accordance with
the foregoing subparagraph (ii) of this Section 11(a), the Company, by a vote of
the Board of Directors, shall: (A) determine the excess of (1) the value of the
Adjustment Shares issuable upon the exercise of a Right (the "Current Value")
over (2) the Purchase Price (such excess being the "Spread"), and (B) with
respect to each Right, make adequate provision to substitute for such Adjustment
Shares, upon payment of the applicable Purchase Price, (1) cash, (2) a reduction
in the Purchase Price, (3) other equity securities of the Company (such other
equity securities being referred to as "capital stock equivalents"), (4) debt
securities of the Company, (5) other assets, or (6) any combination of the
foregoing, having an aggregate value equal to the Current Value, where such
aggregate value has been determined by the Board of Directors, after receiving
advice from a nationally recognized investment banking firm; provided, however,
that if the Company shall not have made adequate provision to deliver value
pursuant to clause (B) above within thirty days following the later of (x) the
first occurrence of a Section 11(a)(ii) Event and (y) the date on which the
Company's right of redemption pursuant to Section 23(a) expires (the later of
(x) and (y) being referred to herein as the "Section 11(a)(ii) Trigger Date"),
then the Company shall be obligated to deliver, upon the surrender for exercise
of a Right and without requiring payment of the Purchase Price, shares of Class
A Common Stock (to the extent available), "capital stock equivalents," and then,
if necessary, cash, which shares or "capital stock equivalents," and/or cash
shall have an aggregate value equal to the Spread. To the extent that the
Company determines that some action need be taken pursuant to the first sentence
of this Section 11(a)(iii), the Company shall provide, subject to Section 7(e)
hereof, that such action shall apply uniformly to all outstanding Rights. For
purposes of this Section 11(a)(iii), the value of the Class A Common Stock shall
be the current market price (as determined pursuant to Section 11(d) hereof) per
share of Class A Common Stock on the Section 11(a)(ii) Trigger Date and the
value of any "capital stock equivalent" shall be deemed to have the same value
as the Class A Common Stock on such date.

                                       13


<PAGE>   17



         (b) In case the Company shall fix a record date for the issuance of
rights, options or warrants to all holders of Preferred Stock entitling them to
subscribe for or purchase (for a period expiring within forty-five calendar days
after such record date) shares of Preferred Stock (or shares having the same
rights, privileges and preferences as shares of Preferred Stock ("equivalent
preferred stock")) or securities convertible into Preferred Stock or equivalent
preferred stock at a price per share of Preferred Stock or per share of
equivalent preferred stock (or having a conversion price per share, if a
security convertible into Preferred Stock or equivalent preferred stock) less
than the current market price (as determined pursuant to Section 11(d) hereof)
per share of Preferred Stock 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 sum of the number of shares of Preferred Stock
outstanding on such record date plus the number of shares of Preferred Stock
which the aggregate offering price of the total number of shares of Preferred
Stock and/or equivalent preferred stock 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 shares of Preferred Stock outstanding on such record date plus the
number of additional shares of Preferred Stock and/or equivalent preferred stock
to be offered for subscription or purchase (or into which the convertible
securities so to be offered are initially convertible). In case such
subscription price may be paid by delivery of consideration part or all of which
may be in a form other than cash, the value of such consideration shall be as
determined in good faith by the Board of Directors, 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. Shares of Preferred Stock owned by
or held for the account of the Company or any Subsidiary 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 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 a distribution to
all holders of shares of Preferred Stock (including any such distribution made
in connection with a share exchange or merger in which the Company is the
continuing corporation) of evidences of indebtedness, cash (other than a regular
quarterly cash dividend out of the earnings or retained earnings of the
Company), assets (other than a dividend payable in shares of Preferred Stock but
including any dividend payable in stock other than Preferred Stock) 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 current market
price (as determined pursuant to Section 11(d) hereof) per share of Preferred
Stock on such record date less the fair market value (as determined in good
faith by the Board of Directors, 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) of the portion of the cash, assets or evidences
of indebtedness so to be distributed or of such subscription rights or warrants
applicable to a share of Preferred Stock and the denominator of which shall be
such current market price (as determined pursuant to Section 11(d) hereof) per
share of Preferred Stock. Such adjustments shall be made successively whenever
such a record date is

                                       14


<PAGE>   18



fixed, and in the event that such distribution is not so made, the Purchase
Price shall be adjusted to be the Purchase Price which would have been in effect
if such record date had not been fixed.

         (d)(i) For the purpose of any computation hereunder, the "current
market price" per share of the Class A Common Stock on any date shall be deemed
to be the average of the daily closing prices per share of such shares for the
ten consecutive Trading Days (as such term is hereinafter defined) immediately
prior to such date; provided, however, if prior to the expiration of such
requisite ten Trading Day period the issuer announces either (A) a dividend or
distribution on such shares payable in such shares or securities convertible
into such shares (other than the Rights), or (B) any subdivision, combination or
reclassification of such shares, then, following the ex-dividend date for such
dividend or the record date for such subdivision, as the case may be, the
"current market price" shall be properly adjusted to take into account such
event. The closing price for each day shall be, if the shares are listed and
admitted to trading on a national securities exchange, as reported in the
principal consolidated transaction reporting system with respect to securities
listed on the principal national securities exchange on which such shares are
listed or admitted to trading or, if such shares are not listed or admitted to
trading on any national securities exchange, the last quoted sales 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 National Association of Securities
Dealers, Inc. Automated Quotation System ("NASDAQ") or such other system then in
use, or, if on any such date such shares 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 such shares selected by the Board
of Directors. If on any such date no market maker is making a market in such
shares, the fair value of such shares on such date as determined in good faith
by a majority of the Board of Directors shall be used. If such shares are not
publicly held or not so listed or traded, "current market price" per share shall
mean the fair value per share as determined in good faith by the Board of
Directors, whose determination shall be described in a statement filed with the
Rights Agent and shall be conclusive for all purposes. The term "Trading Day"
shall mean regular trading hours on a Business Day or, if such shares are listed
or admitted to trading on any national securities exchange, a day on which the
principal national securities exchange on which such shares are listed or
admitted to trading is open for the transaction of business.

                  (ii) For the purpose of any computation hereunder, the
"current market price" per share of Preferred Stock shall be determined in the
same manner as set forth above for the Class A Common Stock in clause (i) of
this Section 11(d) (other than the fourth sentence thereof). If the current
market price per share of Preferred Stock cannot be determined in the manner
provided above or if the Preferred Stock is not publicly held or listed or
traded in a manner described in clause (i) of this Section 11(d), the "current
market price" per share of Preferred Stock shall be conclusively deemed to be an
amount equal to 100 (as such amount may be appropriately adjusted for such
events as stock splits, stock dividends and recapitalizations with respect to
Company Common Stock occurring after the date of this Agreement) multiplied by
the current market price per share of the Class A Common Stock. If neither the
Class A Common Stock nor Preferred Stock is publicly held or so listed or
traded, "current market price" per share of the Preferred Stock shall mean the
fair value per share as determined in good faith by the Board of Directors whose
determination shall be

                                       15


<PAGE>   19



described in a statement filed with the Rights Agent and shall be binding on the
Rights Agent and the holders of the Rights. For all purposes of this Agreement,
the "current market price" of a Unit of Preferred Stock shall be equal to the
"current market price" of one share of Preferred Stock divided by 100.

         (e) Anything herein to the contrary notwithstanding, no adjustment in
the Purchase Price shall be required unless such adjustment would require an
increase or decrease of at least one percent (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 ten-thousandth of a share of Company
Common Stock or Common Stock or other share or one-millionth of a share of
Preferred Stock, 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
mandates such adjustment or (ii) the Expiration Date.

         (f) If as a result of an adjustment made pursuant to Sections 11(a)(ii)
or 13(a) hereof, the holder of any Right thereafter exercised shall become
entitled to receive any shares of capital stock other than Preferred Stock,
thereafter the number of such other shares so receivable upon exercise of any
Right and the Purchase Price thereof shall be subject to adjustment from time to
time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to the Preferred Stock contained in Sections 11(a), (b),
(c), (e), (g), (h), (i), (j), (k), and (m), and the provisions of Sections 7, 9,
10, 13 and 14 hereof with respect to the Preferred Stock 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 Units of Preferred Stock
(or other securities or amount of cash or combination thereof) that may be
acquired 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 Units of Preferred
Stock (or other securities) (calculated to the nearest one-millionth of a share)
obtained by (i) multiplying (x) the number of Units of Preferred Stock (or other
securities) 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 (ii) 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 lieu of any adjustment in the
number of Units of Preferred Stock

                                       16


<PAGE>   20



(or other securities) that may be acquired upon the exercise of a Right. Each of
the Rights outstanding after the adjustment in the number of Rights shall be
exercisable for the number of Units of Preferred Stock (or other securities) 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 ten-thousandth) 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 Rights Certificates have been issued, shall be at least
ten days later than the date of such public announcement. If Rights 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 Rights Certificates on such record date
Rights 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 Rights Certificates held by
such holders prior to the date of adjustment, and upon surrender thereof, if
required by the Company, new Rights Certificates evidencing all the Rights to
which such holders shall be entitled after such adjustment. Rights Certificates
to be so distributed shall be issued, executed and countersigned in the manner
provided for herein (and may bear, at the option of the Company, the adjusted
Purchase Price) and shall be registered in the names of the holders of record of
Rights 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 Units of Preferred Stock (or other securities) issuable upon the
exercise of the Rights, the Rights Certificates theretofore and thereafter
issued may continue to express the Purchase Price per Unit and the number of
Units of Preferred Stock which was expressed in the initial Rights Certificates
issued hereunder.

         (k) Before taking any action that would cause an adjustment reducing
the Purchase Price below the then par value of the number of Units of Preferred
Stock 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 such fully paid and nonassessable number
of Units of Preferred Stock (or other securities) 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 issuance to the holder of any Right exercised after such record date
of that number of Units of Preferred Stock and shares of other capital stock or
securities of the Company, if any, issuable upon such exercise over and above
the number of Units of Preferred Stock and shares of 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

                                       17


<PAGE>   21



Company shall deliver to such holder a due bill or other appropriate instrument
evidencing such holder's right to receive such additional shares (fractional or
otherwise) or securities 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 in their good faith judgment the Board of Directors shall
determine to be advisable in order that any (i) consolidation or subdivision of
the Preferred Stock, (ii) issuance wholly for cash of any shares of Preferred
Stock at less than the current market price, (iii) issuance wholly for cash of
shares of Preferred Stock or securities which by their terms are convertible
into or exchangeable for shares of Preferred Stock, (iv) stock dividends or (v)
issuance of rights, options or warrants referred to in this Section 11,
hereafter made by the Company to holders of its Preferred Stock, shall not be
taxable to such holders or shall reduce the taxes payable by such holders.

         (n) The Company shall not, at any time after the Distribution Date, (i)
effect a share exchange with any other Person (other than a Subsidiary of the
Company in a transaction which complies with Section 11(o) hereof), (ii) merge
with or into any other Person (other than a Subsidiary of the Company in a
transaction which complies with Section 11(o) hereof), or (iii) sell or transfer
(or permit any Subsidiary to sell or transfer), in one transaction, or a series
of transactions, assets or earning power aggregating more than 50% of the assets
or earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person or Persons (other than the Company and/or any of its Subsidiaries
in one or more transactions each of which complies with Section 11(o) hereof),
if (x) at the time of or immediately after such share exchange, merger or sale
there are any rights, warrants or other instruments or securities outstanding or
agreements in effect which would substantially diminish or otherwise eliminate
the benefits intended to be afforded by the Rights or (y) prior to,
simultaneously with or immediately after such share exchange, merger or sale,
the Person which constitutes, or would constitute, the "Principal Party" for
purposes of Section 13(a) hereof shall have distributed or otherwise transferred
to its shareholders or other persons holding an equity interest in such Person
Rights previously owned by such Person or any of, its Affiliates and Associates;
provided, however, this Section 11(n) shall not affect the ability of any
Subsidiary of the Company to effect a share exchange with, merge with or into,
or sell or transfer assets or earning power to, any other Subsidiary of the
Company.

         (o) After the Distribution Date, the Company shall not, except as
permitted by Section 23 or Section 27 hereof, take (or permit any Subsidiary to
take) any action if at the time such action is taken it is reasonably
foreseeable that such action will diminish substantially or otherwise eliminate
the benefits intended to be afforded by the Rights.

         (p) Anything in this Agreement to the contrary notwithstanding, in the
event that the Company shall at any time after the Rights Dividend Declaration
Date and prior to the Distribution Date (i) declare a dividend on the
outstanding shares of Company Common Stock payable in shares of Company Common
Stock, (ii) subdivide the outstanding shares of Company Common Stock, (iii)

                                       18

combine the outstanding shares of Company Common Stock into a smaller number of
shares, or (iv) issue any shares of its capital stock in a reclassification of
Company Common Stock (including any such reclassification in connection with a
share exchange or merger in which the Company is not the continuing or surviving
corporation), the number of Rights associated with each share of Company Common
Stock then outstanding, or issued or delivered thereafter but prior to the
Distribution Date, shall be proportionately adjusted so that the number of
Rights thereafter associated with each share of Company Common Stock following
any such event shall equal the result obtained by multiplying the number of
Rights associated with each share of Company Common Stock immediately prior to
such event by a fraction the numerator of which shall be the total number of
shares of Company Common Stock outstanding immediately prior to the occurrence
of the event and the denominator of which shall be the total number of shares of
Company Common Stock outstanding immediately following the occurrence of such
event.

         Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Section 11 and Section 13 hereof,
the Company shall (a) promptly prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) promptly file with the Rights Agent, and with each transfer agent for the
Preferred Stock and the Company Common Stock, a copy of such certificate, and
(c) mail a brief summary thereof to each holder of a Rights Certificate (or, if
prior to the Distribution Date, to each holder of a certificate representing
shares of Company Common Stock) in accordance with Section 26 hereof. The Rights
Agent shall be fully protected in relying on any such certificate and on any
adjustment therein contained and shall not be deemed to have knowledge of any
such Adjustment unless and until it shall have received such certificate.

         Section 13. Share Exchange, Merger or Sale or Transfer of Assets or
Earning Power.

         (a) In the event that, following the Stock Acquisition Date, directly
or indirectly, either (x) the Company shall effect a share exchange with, or
merge with and into, any other Person (other than a Subsidiary of the Company in
a transaction which complies with Section 11(o) hereof), and the Company shall
not be the continuing or surviving corporation of such share exchange or merger,
(y) any Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof) shall effect a share exchange with, or merge
with or into, the Company, and the Company shall be the continuing or surviving
corporation of such share exchange or merger and, in connection with such share
exchange or merger, all or part of the outstanding shares of Company Common
Stock shall be converted into or exchanged for stock or other securities of any
other Person or cash or any other property, or (z) the Company shall sell or
otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise
transfer) to any Person or Persons (other than the Company or any of its
Subsidiaries in one or more transactions each of which complies with Section
11(o) hereof), in one or more transactions, assets or earning power aggregating
more than 50% of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) (any such event being a "Section 13 Event"), then, and in
each such case, proper provision shall be made so that: (i) each holder of a
Right, except as provided in Section 7(e) hereof, shall thereafter have the
right to receive, upon the exercise thereof at the then current Purchase Price,
such number of validly

                                       19


<PAGE>   23



authorized and issued, fully paid and nonassessable shares of Common Stock of
the Principal Party (as such term is hereinafter defined), which shares shall
not be subject to any liens, encumbrances, rights of first refusal, transfer
restrictions or other adverse claims, as shall be equal to the result obtained
by (1) multiplying the then current Purchase Price by the number of Units of
Preferred Stock for which a Right is exercisable immediately prior to the first
occurrence of a Section 13 Event (or, if a Section 11(a)(ii) Event has occurred
prior to the first occurrence of a Section 13 Event, multiplying the number of
such Units for which a Right would be exercisable hereunder but for the
occurrence of such Section 11(a)(ii) Event by the Purchase Price which would be
in effect hereunder but for such first occurrence) and dividing that product
(which, following the first occurrence of a Section 13 Event, shall be the
"Purchase Price" for all purposes of this Agreement) by (2) 50% of the current
market price (determined pursuant to Section 11(d) hereof) per share of the
Common Stock of such Principal Party on the date of consummation of such Section
13 Event; (ii) such Principal Party shall thereafter be liable for, and shall
assume, by virtue of such Section 13 Event, all the obligations and duties of
the Company pursuant to this Agreement; (iii) the term "Company" shall
thereafter be deemed to refer to such Principal Party, it being specifically
intended that the provisions of Section 11 hereof shall apply only to such
Principal Party following the first occurrence of a Section 13 Event; (iv) such
Principal Party shall take such steps (including, but not limited to, the
reservation of a sufficient number of shares of its Common Stock) in connection
with the consummation of any such transaction as may be necessary to ensure that
the provisions of this Agreement shall thereafter be applicable to its shares of
Common Stock thereafter deliverable upon the exercise of the Rights; and (v) the
provisions of Section 11(a)(ii) hereof shall be of no further effect following
the first occurrence of any Section 13 Event.

         (b) "Principal Party" shall mean:

             (i) in the case of any transaction described in clause (x) or (y)
of the first sentence of Section 13(a), (A) the Person that is the issuer of any
securities into which shares of Company Common Stock are converted in such
merger or share exchange, or, if there is more than one such issuer, the issuer
of Common Stock that has the highest aggregate current market price (determined
pursuant to Section 11(d) hereof); and (B) if no securities are so issued, the
Person that is the other party to such merger or share exchange, or, if there is
more than one such Person, the Person the Common Stock of which has the highest
aggregate current market price (determined pursuant to Section 11(d) hereof);
and

             (ii) in the case of any transaction described in clause (z) of the
first sentence of Section 13(a), the Person that is the party receiving the
largest portion of the assets or earning power transferred pursuant to such
transaction or transactions, or, if each Person that is a party to such
transaction or transactions receives the same portion of the assets or earning
power transferred pursuant to such transaction or transactions or if the Person
receiving the largest portion of the assets or earning power cannot be
determined, whichever Person the Common Stock of which has the highest aggregate
current market price (determined pursuant to Section 11(d) hereof); provided,
however, that in any such case, (1) if the Common Stock of such Person is not at
such time and has not been continuously over the preceding twelve-month period
registered under Section 12 of the

                                       20


<PAGE>   24



Exchange Act ("Registered Common Stock"), or such Person is not a corporation,
and such Person is a direct or indirect Subsidiary of another Person that has
Registered Common Stock outstanding, "Principal Party" shall refer to such other
Person; (2) if the Common Stock of such Person is not Registered Common Stock or
such Person is not a corporation, and such Person is a direct or indirect
Subsidiary of another Person but is not a direct or indirect Subsidiary of
another Person which has Registered Common Stock outstanding, "Principal Party"
shall refer to the ultimate parent entity of such first-mentioned Person; (3) if
the Common Stock of such Person is not Registered Common Stock or such Person is
not a corporation, and such Person is directly or indirectly controlled by more
than one Person, and one or more of such other Persons has Registered Common
Stock outstanding, "Principal Party" shall refer to whichever of such other
Persons is the issuer of the Registered Common Stock having the highest
aggregate current market price (determined pursuant to Section 11(d) hereof);
and (i) if the Common Stock of such Person is not Registered Common Stock or
such Person is not a corporation, and such Person is directly or indirectly
controlled by more than one Person, and none of such other Persons have
Registered Common Stock outstanding, "Principal Party" shall refer to whichever
ultimate parent entity is the corporation having the greatest stockholders
equity or, if no such ultimate parent entity is a corporation, shall refer to
whichever ultimate parent entity is the entity having the greatest net assets.

         (c) The Company shall not consummate any such share exchange, merger,
sale or transfer unless the Principal Party shall have a sufficient number of
authorized shares of its Common Stock which have not been issued or reserved for
issuance to permit the exercise in full of the Rights in accordance with Section
13, and unless prior thereto the Company and such Principal Party shall have
executed and delivered to the Rights Agent a supplemental agreement providing
for the terms set forth in paragraphs (a) and (b) of this Section 13 and further
providing that the Principal Party will:

             (i)(A) file on an appropriate form, as soon as practicable
following the execution of such agreement, a registration statement under the
Securities Act with respect to the Common Stock that may be acquired upon
exercise of the Rights, (B) cause such registration statement to remain
effective (and to include a prospectus complying with the requirement of the
Securities Act) until the Expiration Date, and (C) as soon as practicable
following the execution of such agreement, take such action as may be required
to ensure that any acquisition of such Common Stock upon the exercise of the
Rights complies with any applicable state security or "blue sky" laws; and

             (ii) will deliver to holders of the Rights historical financial
statements for the Principal Party and each of its Affiliates which comply in
all respects with the requirements for registration on Form 10 under the
Exchange Act.

         (d) In case the Principal Party which is to be a party to a transaction
referred to in this Section 13 has a provision in any of its authorized
securities or in its charter or bylaws or other instrument governing its
corporate affairs, which provision would have the effect of (i) causing such
Principal Party to issue, in connection with, or as a consequence of, the
consummation of a transaction referred to in this Section 13, shares of Common
Stock of such Principal Party at less

                                       21


<PAGE>   25



than the then current market price per share (determined pursuant to Section
11(d) hereof) or securities exercisable for, or convertible into, Common Stock
of such Principal Party at less than such then current market price (other than
to holders of Rights pursuant to this Section 13) or (ii) providing for any
special payment, tax or similar provisions in connection with the issuance of
the Common Stock of such Principal Party pursuant to the provisions of Section
13; then, in such event, the Company shall not consummate any such transaction
unless prior thereto the Company and such Principal Party shall have executed
and delivered to the Rights Agent a supplemental agreement providing that the
provision in question of such Principal Party shall have been canceled, waived
or amended, or that the authorized securities shall be redeemed, so that the
applicable provision will have no effect in connection with, or as a consequence
of, the consummation of the proposed transaction.

         (e) The provisions of this Section 13 shall similarly apply to
successive mergers or share exchanges or mergers or other transfers. In the
event that a Section 13 Event shall occur at any time after the occurrence of a
Section 11(a)(ii) Event, the Rights which have not theretofore been exercised
shall thereafter become exercisable in the manner described in Section 13(a).

         Section 14. Fractional Rights and Fractional Shares.

         (a) The Company shall not be required to issue fractions of Rights or
to distribute Rights Certificates which evidence fractional Rights. In lieu of
such fractional Rights, there shall be paid to the Persons to which such
fractional Rights would otherwise be issuable, an amount in cash equal to such
fraction of the market value of a whole Right. For purposes of this Section
14(a), the 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 of the
Rights for any day shall be, if the Rights are listed or admitted to trading on
a national securities 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 sales 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. If on any such 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 shall be used
and such determination shall be described in a statement filed with the Rights
Agent and the holders of the Rights.

         (b) The Company shall not be required to issue fractions of shares of
Preferred Stock (other than fractions which are integral multiples of one
one-hundredth of a share of Preferred Stock) (or other securities) upon exercise
of the Rights or to distribute certificates which evidence such fractional
shares of Preferred Stock (other than fractions which are integral multiples of
one one-hundredth of a share of Preferred Stock) (or other securities). In lieu
of such fractional shares of

                                       22


<PAGE>   26



Preferred Stock that are not integral multiples of one one-hundredth of a share
(or other securities), the Company may pay to the registered holders of Rights
Certificates at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of the then current market value of one
one-hundredth of a share of Preferred Stock (or other securities). For purposes
of this Section 14(b), the current market value of one one-hundredth of a share
of Preferred Stock (or other securities) shall be the closing price of one
one-hundredth of a share of Preferred Stock (or other securities) (as the term
"closing price" is used in Section 11(d) hereof) for the Trading Day immediately
prior to the date of such exercise.

         (c) The holder of a Right by the acceptance of the Rights expressly
waives his right to receive any fractional Rights or any fractional shares upon
exercise of a Right, except as permitted by this Section 14.

         Section 15. Rights of Action. All rights of action in respect of this
Agreement, other than rights of action vested in the Rights Agent pursuant to
Section 18 hereof, are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of
certificates representing shares of Company Common Stock); and any registered
holder of a Rights Certificate (or, prior to the Distribution Date, of a
certificate representing shares of Company Common Stock), without the consent of
the Rights Agent or of the holder of any other Rights Certificate (or, prior to
the Distribution Date, of a certificate representing shares of Company Common
Stock), may, in his own behalf and for his own benefit, enforce, and may
institute and maintain any suit, action or proceeding against the Company or any
other Person to enforce, or otherwise act in respect of, his right to exercise
the Rights evidenced by such Rights Certificate in the manner provided in such
Rights Certificate and in this Agreement. Without limiting the foregoing or any
remedies available to the holders of Rights, it is specifically acknowledged
that the holders of Rights would not have an adequate remedy at law for any
breach of this Agreement and shall be entitled to specific performance of the
obligations hereunder and injunctive relief against actual or threatened
violations of the obligations hereunder of any Person subject to this Agreement.

         Section 16. Agreement of Rights 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 shall be transferable
only in connection with the transfer of Company Common Stock;

         (b) after the Distribution Date, the Rights Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the office of the Rights Agent designated for such purposes, duly endorsed or
accompanied by a proper instrument of transfer and with the appropriate forms
and certificates duly executed;

         (c) subject to Section 6(a) and Section 7(f) hereof, the Company and
the Rights Agent may deem and treat the person in whose name a Rights
Certificate (or, prior to the Distribution Date,

                                       23


<PAGE>   27



the associated Company Common Stock certificate) is registered as the absolute
owner thereof and of the Rights evidenced thereby (notwithstanding any notations
of ownership or writing on the Rights Certificates or the associated Company
Common Stock certificate made by anyone other than the Company or the Rights
Agent) for all purposes whatsoever, and neither the Company nor the Rights
Agent, subject to the last sentence of Section 7(e) hereof, shall be affected by
any notice to the contrary; and

         (d) notwithstanding anything to the contrary, neither the Company nor
the Rights Agent shall have any liability to any holder of a Right or any other
Person as a result of its inability to perform any of its obligations under this
Agreement by reason of any preliminary or permanent injunction or other order,
decree or ruling issued by a court of competent jurisdiction or by a
governmental, regulatory or administrative agency or commission, or any statute,
rule, regulation or executive order promulgated or enacted by any governmental
authority, prohibiting or otherwise restraining performance of such obligation;
provided, however, the Company must use its best efforts to have any such order,
decree or ruling lifted or otherwise overturned as promptly as practicable.

         Section 17. Rights Certificate Holder Not Deemed a Shareholder. No
holder, as such, of any Rights Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the number of shares of
Preferred Stock 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 Rights Certificate be construed to confer upon the
holder of any Rights Certificate, as such, any of the rights of a shareholder of
the Company or any right to vote for the election of directors or upon any
matter submitted to shareholders at any meeting thereof, or to give or withhold
consent to any corporate action, or, except as provided in Section 25 hereof, to
receive notice of meetings or other actions affecting shareholders, or to
receive dividends or subscription rights, or otherwise, until the Right or
Rights evidenced by such Rights 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, including reasonable
fees and disbursements of its counsel, incurred in connection with the execution
and administration of this Agreement and the exercise and performance of its
duties hereunder. The Company shall indemnify the Rights Agent for, and hold it
harmless against, any losses, expenses, claims, damages or liabilities incurred
without gross 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 Agreement and performance
hereunder, including without limitation the costs and expenses of defending
against any claim of liability therefrom, directly or indirectly and will
promptly reimburse the Rights Agent for legal and other expenses reasonably
incurred in defending any such loss, expense, claim, damage or liability.

                                       24


<PAGE>   28



         (b) The Rights Agent shall be protected by the indemnity provided by
this Section and shall incur no liability for or in respect of any action taken,
suffered or omitted by it in connection with its administration of this
Agreement in reliance upon any Rights Certificate or certificate for Company
Common Stock 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 have been signed, executed and, where necessary, verified or
acknowledged by the proper Person or Persons.

         Section 19. Merger or Share Exchange 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 effect a share exchange, or any
corporation resulting from any merger or share exchange to which the Rights
Agent or any successor Rights Agent shall be a party, or any corporation
succeeding to the corporate trust or shareholder services businesses of the
Rights Agent or any successor Rights Agent, shall be the successor to the Rights
Agent under this Agreement without the execution or filing of any document or
any further act on the part of any of the parties hereto; provided, however,
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 Agreement,
any of the Rights Certificates shall have been countersigned but not delivered,
any such successor Rights Agent may adopt the countersignature of predecessor
Rights Agent and deliver such Rights Certificates so countersigned; and in case
at that time any of the Rights Certificates shall not have been countersigned,
any successor Rights Agent may countersign such Rights Certificates either in
the name of the predecessor or in the name of the successor Rights Agent; and in
all such cases such Rights Certificates shall have the full force provided in
the Rights Certificates and in this Agreement.

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

         Section 20. Duties of Rights Agent. The Rights Agent undertakes the
duties and obligations imposed by this Agreement upon the following terms and
conditions, by all of which the Company and the holders of Rights Certificates,
by their acceptance thereof, shall be bound:

         (a) The Rights Agent may consult with legal counsel (who may be legal
counsel for the Company), and the 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.

                                       25


<PAGE>   29



         (b) Whenever in the performance of its duties under this Agreement the
Rights Agent shall deem it necessary or desirable that any fact or matter
(including, without limitation, the identity of any Acquiring Person and the
determination of "current market price") 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 specified herein) may be deemed to be
conclusively proved and established by a certificate signed by the Chairman of
the Board, the President, any Vice President, the Treasurer, any Assistant
Treasurer, the Secretary or any Assistant Secretary of the Company and delivered
to the Rights Agent; provided, however, that so long as any Person is an
Acquiring Person hereunder, such certificate shall be signed and delivered by
the Board of Directors; 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 Agreement in reliance upon such certificate.

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

         (d) The Rights Agent shall not have any responsibility for the validity
or legality of this Agreement or the execution and delivery hereof (except the
due execution hereof by the Rights Agent) or for the validity, legality or
execution of any Rights Certificate (except its countersignature thereof); nor
shall it be responsible for any breach by the Company of any covenant or failure
by the Company to satisfy conditions contained in this Agreement or in any
Rights Certificate; nor shall it be responsible for any adjustment required
under the provisions of Section 11 or Section 13 hereof or for the manner,
method or amount of any such adjustment or the ascertaining of the existence of
facts that would require any such adjustment (except with respect to the
exercise of Rights evidenced by Rights Certificates after receipt by the Rights
Agent of the certificate describing any such adjustment contemplated by Section
12); nor shall it by any act hereunder be deemed to make any representation or
warranty as to the authorization or reservation of any shares of Class A Common
Stock or any other securities to be issued pursuant to this Agreement or any
Rights Certificate or as to whether any shares of Class A Common Stock or any
other securities will, when so issued, be validly authorized and issued, fully
paid and nonassessable.

         (e) The Company shall perform, execute, acknowledge and deliver or
cause to be performed, executed, acknowledged and delivered all such further
acts, instruments and assurances as may reasonably be required by the Rights
Agent for the performance by the Rights Agent of its duties under this
Agreement.

         (f) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from the
Chairman of the Board, the President, any Vice President, the Secretary, any
Assistant Secretary, the Treasurer or any Assistant 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 to the Company, the holder of any Rights
Certificate or any shareholder of the Company for any action taken or suffered
to be taken by it in good faith in accordance with

                                       26


<PAGE>   30



instructions of any such officer; provided, however, that so long as any Person
is an Acquiring Person hereunder, the Rights Agent shall accept such
instructions and advice only from the Board of Directors and shall not be liable
for any action taken or suffered to be taken by it in good faith in accordance
with such instructions of the Board of Directors. Any application by the Rights
Agent for written instructions from the Company may, at the option of the Rights
Agent, set forth in writing any action proposed to be taken or omitted by the
Rights Agent under this Rights Agreement and the date on and/or after which such
action shall be taken or such omission shall be effective. The Rights Agent
shall not be liable for any action taken by, or omission of, the Rights Agent in
accordance with a proposal included in any such application on or after the date
specified in such application (which date shall not be less than five Business
Days after the date any such officer of the Company actually receives such
application, unless any such officer shall have consented in writing to an
earlier date) unless, prior to taking any such action (or the effective date in
the case of an omission), the Rights Agent shall have received written
instructions in response to such application specifying the action to be taken
or omitted.

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

         (h) 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 if reasonable care was exercised in the selection and
continued employment thereof.

         (i) No provision of this Agreement shall require the Rights Agent to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties or in the exercise of its rights hereunder if
the Rights Agent in its sole judgment shall have reasonable grounds for
believing that repayment of such funds or adequate indemnification against such
risk or liability is not reasonably assured to it.

         (j) If, with respect to any Rights Certificate surrendered to the
Rights Agent for exercise or transfer, the certificate attached to the form of
assignment or form of election to purchase, as the case may be, has either not
been completed, not signed or indicates an affirmative response to clause 1
and/or 2 thereof, the Rights Agent shall not take any further action with
respect to such requested exercise of transfer without first consulting with the
Company. If such certificate has been completed and signed, the Rights Agent may
assume without further inquiry that the Rights Certificate is not owned by a
person described in Section 4(b) or Section 7(e) hereof and shall not be charged
with any knowledge to the contrary.

         Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon thirty days' notice in writing mailed to the Company, and to each transfer
agent of the Preferred Stock and the Company Common Stock, by registered or
certified mail, and to the holders of the Rights Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
thirty 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 Preferred Stock and
the Company Common Stock, by registered or certified mail, and to the holders of
the Rights 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 thirty 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 Rights
Certificate (who shall, with such notice, submit his Rights Certificate for
inspection by the Company), then any registered holder of any Rights 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
such a court, shall be a corporation organized and doing business under the laws
of the United States or any state of the United States in good standing and may
be the Company or a Subsidiary of the Company. 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 Preferred Stock and the Company Common Stock, and
mail a notice thereof in writing to the registered holders of the Rights
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.

         Section 22. Issuance of New Rights Certificates. Notwithstanding any of
the provisions of this Agreement or the Rights to the contrary, the Company may,
at its option, issue new Rights Certificates evidencing Rights in such form as
may be approved by the Board of Directors to reflect any adjustment or change
made in accordance with the provisions of this Agreement in the Purchase Price
or the number or kind or class of shares or other securities or property that
may be acquired under the Rights Certificates. In addition, in connection with
the issuance or sale of shares of Company Common Stock following the
Distribution Date and prior to the Expiration Date, the Company (a) shall, with
respect to shares of Company Common Stock so issued or sold pursuant to the
exercise of stock options or under any employee plan or arrangement, or upon the
exercise, conversion or exchange of securities hereinafter issued by the
Company, and (b) may, in any other case, if deemed necessary or appropriate by
the Board of Directors, issue Rights Certificates representing the appropriate
number of Rights in connection with such issuance or sale; provided, however,
that (i) no such Rights Certificate shall be issued if, and to the extent that,
the Company shall be advised by counsel that such issuance would create a
significant risk of material adverse tax

                                       28


<PAGE>   32



consequences to the Company or the person to whom such Rights Certificate would
be issued, and (ii) no such Rights Certificate shall be issued if, and to the
extent that, appropriate adjustment shall otherwise have been made in lieu of
the issuance thereof.

         Section 23. Redemption and Termination.

         (a) Subject to Section 31 hereof, the Company may, at its option, by
action of the Board of Directors, at any time prior to the earlier of (i) the
Close of Business on the tenth day following the Stock Acquisition Date, or (ii)
the Final Expiration Date, redeem all but not less than all of the then
outstanding Rights at a redemption price of $0.001 per Right, as such amount may
be appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof (such redemption price being the
"Redemption Price"), and the Company may, at its option, by action of the Board
of Directors, pay the Redemption Price either in shares of Class A Common Stock
(based on the "current market price," as defined in Section 11(d) hereof, of the
shares of Class A Common Stock at the time of redemption) or cash; provided that
if the Company elects to pay the Redemption Price in shares of Class A Common
Stock, the Company shall not be required to issue fractional shares of Class A
Common Stock. In lieu of such fractional shares of Class A Common Stock, the
Company shall pay to the registered holders of the Right Certificates with
regard to which such fractional shares of Class A Common Stock would otherwise
be issuable an amount of cash equal to the same fraction of the current per
share market price of a whole share of Class A Common Stock. Notwithstanding
anything in this Agreement to the contrary, the Rights shall not be exercisable
after the first occurrence of a Section 11(a)(ii) Event until such time as the
Company's right of redemption hereunder has expired.

         (b) Immediately upon the action of the Board of Directors ordering the
redemption of the Rights, evidence of which shall be filed with the Rights
Agent, and without any further action and without any notice, the right to
exercise the Rights will terminate and the only right thereafter of the holders
of Rights shall be to receive the Redemption Price for each Right so held.
Promptly after the action of the Board of Directors ordering the redemption of
the Rights, the Company shall give notice of such redemption to the Rights Agent
and the holders of the then outstanding Rights by mailing such notice to all
such holders at each holder's last address as it appears upon the registry books
of the Rights Agent or, prior to the Distribution Date, on the registry books of
the transfer agent for Company Common Stock. 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 shares
of Company Common Stock prior to the Distribution Date.

                                       29

         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 provisions of Section 7(e) hereof) for Class A
Common Stock at an exchange ratio of one share of Class A Common Stock per
Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (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 Company Common Stock for or pursuant to the terms of any such
plan), together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of fifty percent (50%) or more of the Company Common Stock then
outstanding.

         (b) Immediately upon the action of the Board of Directors of the
Company ordering the exchange of any Rights pursuant to subsection (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 shares of Class A Common Stock
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 Company. 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 Class A Common Stock 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 become void pursuant to
the provisions of Section 7(e) hereof) held by each holder of Rights.

         (c) In the event that there shall not be sufficient Class A Common
Stock 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
shares of Class A Common Stock for issuance upon exchange of the Rights. In the
event that the Company shall, after good faith effort, be unable to take all
such action as may be necessary to authorize such additional shares of Class A
Common Stock, the Company shall substitute, for each share of Class A Common
Stock that would otherwise be issuable upon exchange of a Right, a number of
shares of Preferred Stock or fraction thereof such that the current per share
market price of one share of Preferred Stock multiplied by such number or
fraction is equal to the current per share market price of one share of Class A
Common Stock as of the date of issuance of such shares of Preferred Stock or
fraction thereof.

                                       30


<PAGE>   34



         (d) The Company shall not be required to issue fractional shares of
Class A Common Stock or to distribute certificates which evidence fractional
shares of Class A Common Stock. In lieu of such fractional shares of Class A
Common Stock, the Company shall pay to the registered holders of the Right
Certificates with regard to which such fractional shares of Class A Common Stock
would otherwise be issuable an amount in cash equal to the same fraction of the
current per share market price of a whole share of Class A Common Stock. For the
purposes of this paragraph (d), the current market price of a whole share of
Class A Common Stock shall be the closing price of a share of Class A Common
Stock (as determined pursuant to Section 11(d) 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 shall propose, at any time after the
Distribution Date, (i) to pay any dividend payable in stock of any class to the
holders of Preferred Stock or to make any other distribution to the holders of
Preferred Stock (other than a regular quarterly cash dividend out of earnings or
retained earnings of the Company), (ii) to offer to the holders of Preferred
Stock rights or warrants to subscribe for or to purchase any additional shares
of Preferred Stock or shares of stock of any class or any other securities,
rights or options, (iii) to effect any reclassification of its Preferred Stock
(other than a reclassification involving only the subdivision of outstanding
shares of Preferred Stock), (iv) to effect any share exchange or merger into or
with any other Person (other than a Subsidiary of the Company in a transaction
which complies with Section 11(o) hereof), 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 more than 50% of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person or Persons (other than the Company and/or any of its Subsidiaries
in one or more transactions each of which complies with Section 11(o) hereof),
or (v) to effect the liquidation, dissolution or winding up of the Company,
then, in each such case, the Company shall give to each holder of a Rights
Certificate, to the extent feasible and 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, distribution of rights or warrants, or the date
on which such reclassification, share exchange, merger, sale, transfer,
liquidation, dissolution, or winding up is to take place and the date of
participation therein by the holders of the shares of Preferred Stock, 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 twenty (20) days prior to
the record date for determining holders of the shares of Preferred Stock for
purposes of such action, and in the case of any such other action, at least
twenty (20) days prior to the date of the taking of such proposed action or the
date of participation therein by the holders of the shares of Preferred Stock
whichever shall be the earlier; provided, however, no such notice shall be
required pursuant to this Section 25, if any Subsidiary of the Company effects a
share exchange or merger with or into, or effects a sale or other transfer of
assets or earnings power to, any other Subsidiary of the Company.

         (b) In case any of the events set forth in Section 11(a)(ii) hereof
shall occur, then, in any such case, the Company shall as soon as practicable
thereafter give to each holder of a Rights Certificate, to the extent feasible
and in accordance with Section 26 hereof, a notice of the

                                       31


<PAGE>   35



occurrence of such event, which shall specify the event and the consequences of
the event to holders of Rights under Section 11(a)(ii) hereof.

         Section 26. Notices. All notices and other communications provided for
hereunder shall, unless otherwise stated herein, be in writing (including by
telex, telegram or cable) and mailed or sent or delivered, if to the Company, at
its address at:

         AmSurg Corp.
         20 Burton Hills Boulevard
         Nashville, TN 37215
         Attention: Chief Executive Officer

And if to the Rights Agent, at its address at:

         SunTrust Bank, Atlanta                  SunTrust Bank, Atlanta
         Attn: Department Manager                Attn: Department Manager
         P.O. Box 4625                           58 Edgewood Avenue

                                                 Atlanta, GA 30303

Notices or demands authorized by this Agreement to be given or made by the
Company or the Rights Agent to the holder of any Rights Certificate (or, if
prior to the Distribution Date, to the holder of certificates representing
shares of Company Common Stock) shall be sufficiently given or made if sent by
first-class mail, postage prepaid, addressed to such holder at the address of
such holder as shown on the registry books of the Rights Agent or, if prior to
the Distribution Date on the registry books of the transfer agent for Company
Common Stock.

         Section 27. Supplements and Amendments. Prior to the Distribution Date
and subject to the penultimate sentence of this Section 27, the Company and the
Rights Agent shall, if the Company so directs, supplement or amend any provision
of this Agreement without the approval of any holders of certificates
representing shares of Company Common Stock; provided, however, that any
supplement or amendment which changes the rights, duties, liabilities, and
indemnification of the Rights Agent under this Agreement shall be effective only
with the consent of the Rights Agent. From and after the Distribution Date and
subject to the penultimate sentence of this Section 27, the Company and the
Rights Agent shall, if the Company so directs, supplement or amend this
Agreement without the approval of any holders of Rights Certificates in order
(i) to cure any ambiguity, (ii) to correct or supplement any provision contained
herein which may be defective or inconsistent with any other provisions herein,
(iii) to shorten or lengthen any time period hereunder, or (iv) to change or
supplement the provisions hereunder in any manner which the Company may deem
necessary or desirable and which shall be consistent with, and for the purpose
of fulfilling, the objectives of the Board of Directors adopting this Agreement;
provided, however, that from and after such time as any Person becomes an
Acquiring Person, this Agreement shall not be amended in any manner which would
adversely affect the interests of the holders of Rights, and provided, however,

                                       32


<PAGE>   36



this Agreement may not be supplemented or amended to lengthen, pursuant to
clause (iii) of this sentence, (A) subject to Section 31 hereof, a time period
relating to when the Rights may be redeemed at such time as the Rights are not
then redeemable, or (B) any other time period unless such lengthening is for the
purpose of protecting, enhancing or clarifying the rights of, and/or the
benefits to, the holders of Rights. Without limiting the foregoing, the Company
may at any time prior to such time as any Person becomes an Acquiring Person
amend this Agreement to change the Purchase Price hereunder. Upon the delivery
of a certificate from an appropriate officer of the Company or, so long as any
Person is an Acquiring Person hereunder, from the Board of Directors which
states that the proposed supplement or amendment is in compliance with the terms
of this Section 27, the Rights Agent shall execute such supplement or amendment.
Notwithstanding anything contained in this Agreement to the contrary, no
supplement or amendment shall be made which changes the Redemption Price, the
Purchase Price, the Expiration Date or the number of Units of Preferred Stock
for which a Right is exercisable without the approval of a majority of the Board
of Directors. Prior to the Distribution Date, the interests of the holders of
Rights shall be deemed coincident with the interests of the holders of Company
Common Stock.

         Section 28. Successors. All the covenants and provisions of this
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. Determinations and Actions by the Board of Directors, etc.
For all purposes of this Agreement, any calculation of the number of shares of
Company Common Stock outstanding at any particular time, including for purposes
of determining the particular percentage of such outstanding shares of Company
Common Stock of which any Person is the Beneficial Owner, shall be made in
accordance with the last sentence of Rule 13d-3(d)(1)(i) of the Exchange Act
Regulations as in effect on the date hereof. Except as otherwise specifically
provided herein, the Board of Directors of the Company shall have the exclusive
power and authority to administer this Agreement and to exercise all rights and
powers specifically granted to the Board of Directors or to the Company, or as
may be necessary or advisable in the administration of this Agreement,
including, without limitation, the right and power (i) to interpret the
provisions of this Agreement, and (ii) to make all determinations deemed
necessary or advisable for the administration of this Agreement. All such
actions, calculations, interpretations and determinations (including, for
purposes of clause (y) below, all omissions with respect to the foregoing) which
are done or made by the Board of Directors in good faith shall (x) be final,
conclusive and binding on the Company, the Rights Agent, the holders of the
Rights and all other parties, and (y) not subject the Board of Directors or any
member thereof to any liability to the holders of the Rights.

         Section 30. Benefits of this Agreement. Nothing in this Agreement shall
be construed to give to any Person other than the Company, the Rights Agent and
the registered holders of the Rights Certificates (and, prior to the
Distribution Date, registered holders of shares of Company Common Stock) any
legal or equitable right, remedy or claim under this Agreement; but this
Agreement shall be for the sole and exclusive benefit of the Company, the Rights
Agent and the registered holders

                                       33


<PAGE>   37



of the Rights Certificates (and, prior to the Distribution Date, registered
holders of shares of Company Common Stock).

         Section 31. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors determines in its good faith judgment that severing the invalid
language from this Agreement would adversely affect the purpose or effect of
this Agreement and the Rights shall not then be redeemable, the right of
redemption set forth in Section 23 hereof shall be reinstated and shall not
expire until the Close of Business on the tenth day following the date of such
determination by the Board of Directors.

         Section 32. Governing Law. This Agreement, each Right and each Rights
Certificate issued hereunder shall be governed by, and construed in accordance
with, the laws of the State of Tennessee applicable to contracts executed in and
to be performed entirely in such State.

         Section 33. Counterparts. This Agreement may be executed in one or more
counterparts, and by the different parties hereto in separate counterparts, each
of which when executed shall be deemed to be an original, but all of which taken
together shall constitute one and the same instrument.

         Section 34. Descriptive Headings. The headings contained in this
Agreement are for descriptive purposes only and shall not affect in any way the
meaning or interpretation of this Agreement.

designated for such purpose, one one-hundredth of a fully paid nonassessable
share of Series C Junior Participating Preferred Stock, no par value (the
"Preferred Stock"), of the Company at the Purchase Price initially of $______
per one one-hundredth of a share (each such one one-hundredth of a share being a
"Unit") of Preferred Stock, upon presentation and surrender of this Rights
Certificate with the Election to Purchase and related certificate duly executed.
The number of Rights evidenced by this Rights Certificate (and the number of
Units which may be purchased upon exercise thereof) set forth above, and the
Purchase Price per Unit set forth above shall be subject to adjustment in
certain events as provided in the Rights Agreement.

         Upon the occurrence of a Section ll(a)(ii) Event (as such term is
defined in the Rights Agreement), if the Rights evidenced by this Rights
Certificate are beneficially owned by an Acquiring Person or an Affiliate or
Associate of any such Acquiring Person (as such terms are defined in the Rights
Agreement) or, under certain circumstances described in the Rights Agreement, a
transferee of any such Acquiring Person, Associate or Affiliate, such Rights
shall become null and void and no holder hereof shall have any right with
respect to such Rights from and after the occurrence of such Section ll(a)(ii)
Event.

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

         This Rights Certificate is subject to all of the terms and conditions
of the Rights Agreement, which terms and conditions are hereby incorporated

holders of the Rights Certificates. Copies of the Rights Agreement are on file
at the principal office of the Company and are available from the Company upon
written request.

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

                                                                       EXHIBIT B


                  Summary of Rights to Purchase Preferred Stock

         On November 19, 1999 our board of directors approved the adoption of
a rights agreement (commonly known as a "poison pill"). The discussion below
describes the rights agreement entered into between us and SunTrust Bank,
Atlanta, as rights agent, dated as of December 2, 1999, as amended and restated
as of December 13, 1999, (the "Rights Agreement") but is not complete, so you
should read it together with the Rights Agreement which you may obtain from us
free of charge.

ISSUANCE OF RIGHTS

         Under the Rights Agreement, we will issue the following stock purchase
rights:

         -        For each share of our Class A Common Stock, no par value per
                  share, outstanding on December 16, 1999 we will issue, one
                  right; and

         -        For each share of our Class B Common Stock, no par value per
                  share, outstanding on December 16, 1999 we will issue one
                  right.

         Rights will only be issued to stockholders of record as of the close of
business on December 16, 1999. In addition, one right will automatically attach
to each share of common stock that we issue between December 16, 1999 and the
time that the rights become exercisable. When exercised, each right will entitle
its holder to purchase from us one one-hundredth of a share (a "unit") of our
Series C Junior Participating Preferred Stock, no par value per share (the
"Series C Preferred Stock"), at an exercise price of $48.00 per unit, subject to
adjustment.

INITIAL EXERCISE OF RIGHTS

         The rights initially will not be exercisable. Instead, the rights will
be attached to and trade with all shares of our common stock outstanding as of,
and issued after December 16, 1999. The rights will separate from the common
stock and will become exercisable upon the earlier of the following events (the
"distribution date"):

         -        The close of business on the tenth business day (or later day
                  as our board of directors may determine) following the first
                  public announcement that a person or group of affiliated or
                  associated persons (other than certain "exempt persons") has
                  acquired beneficial ownership of 15% or more of our shares of
                  Class A Common Stock then outstanding or 15% or more of our
                  shares of Class B Common Stock then outstanding (an "Acquiring
                  Person"); or

         -        The close of business on the tenth business day (or some later
                  day as our board of directors may determine) following the
                  commencement of a tender offer or exchange offer that could
                  result in a person or group becoming the beneficial owner of
                  15% or more of our shares of Class A Common Stock then
                  outstanding or 15% or more of our shares of Class B Common
                  Stock then outstanding.



<PAGE>   48




         The rights will expire at the close of business on December 2, 2009,
unless we redeem or exchange the rights as described below.

         The exempt persons who are not considered Acquiring Persons include (1)
Wasatch Advisors, Inc. and (2) Waddell & Reed Investment Management Company,
Waddell & Reed, Inc., Waddell & Reed Financial, Inc., and Waddell & Reed
Financial Services, Inc. (collectively the "Waddell & Reed Companies") Should
Wasatch become the beneficial owner of an additional share of our Class A Common
Stock or an additional share of our Class B Common Stock after the date of the
Rights Agreement it will no longer be an exempt person provided that it then
falls within the definition of Acquiring Person. Should any of the Waddell &
Reed Companies become the beneficial owner of an additional share of our Class B
Common Stock after the date of the Rights Agreement or such additional shares of
Class A Common Stock as would result in any of them becoming the beneficial
owner of 15% or more of our Class A Common Stock then outstanding, each of the
Waddell & Reed Companies will no longer be an exempt person provided that it
then falls within the definition of Acquiring Person.

EVIDENCE OF RIGHTS

         Until the rights become exercisable:

         -        The rights will be evidenced by and transferred with our
                  common stock certificates; and

         -        New common stock certificates issued after December 16, 1999
                  will contain a notation incorporating the Rights Agreement by
                  reference; and

         -        Any surrender for transfer of any certificates for our common
                  stock will also constitute the transfer of the rights
                  associated with the common stock represented by those
                  certificates.

         As soon as practicable after the rights become exercisable, we will
mail out rights certificates to the holders of our common stock who are eligible
to receive rights. After we mail them out, the separate rights certificates
alone will represent the rights.

EXERCISE AFTER SOMEONE BECOMES AN ACQUIRING PERSON

         After public announcement that a person has become an Acquiring Person,
each holder of a right will have the right to receive upon exercise of the
rights that number of shares of Class A Common Stock (or in our board's
discretion, some other consideration), having a value of two times the then
current purchase price of the right. However, this will not apply to an
Acquiring Person or their associates or affiliates, whose rights will have
become null and void.

         Under certain circumstances, each holder of a right will have the right
to receive upon exercise of the rights common stock of a company acquiring us
having a value equal to two times the then current purchase price of the right.
Each holder of a right will receive the right contemplated

                                       B-2


<PAGE>   49



by this paragraph in the event that, at any time on or after the date it is
publicly announced that a person has become an Acquiring Person:

         -        We consolidate with, or merge with and into, any other person,
                  and we are not the continuing or surviving corporation; or

         -        Any person consolidates with us, or merges with us and we are
                  the continuing or surviving corporation of that merger and, in
                  connection with that merger, all or part of the shares of our
                  common stock are changed into or exchanged for stock or other
                  securities of any other person or cash or any other property;
                  or

         -        We sell or transfer 50% or more of our assets or earning
                  power.

         The holder of a right will continue to have this right whether or not
that holder has previously exercised its right in accordance with the first
paragraph of this subsection. Rights that are or were beneficially owned by an
Acquiring Person may (under certain circumstances specified in the Rights
Agreement) become null and void.

EXCHANGE

         At any time after a person becomes an Acquiring Person, we may exchange
all or part of the outstanding and exercisable rights for shares of our Class A
Common Stock at an exchange ratio specified in the Rights Agreement. We
generally may not make an exchange after any person becomes the beneficial owner
of 50% or more of either our Class A Common Stock or Class B Common Stock.

ADJUSTMENT

         The purchase price and the number of shares of Class A Common Stock or
other securities or property issuable upon exercise of the rights is subject to
adjustment from time to time to prevent certain types of dilution. With certain
exceptions, the purchase price of the rights will not be adjusted until
cumulative adjustments amount to at least 1% of the purchase price. We are not
obligated to issue fractional units or shares of Class A Common Stock. If we
decide not to issue fractional units or shares, we will make an adjustment in
cash based on the fair market value of a unit or share on the last trading date
prior to the date of exercise.

REDEMPTION

         We may redeem the rights in whole, but not in part, at a price of
$0.001 per right (payable in cash, preferred stock or other consideration that
we deem appropriate). However, we may only redeem the rights until the earlier
of ten days after someone becomes an Acquiring Person or December 2, 2009.

                                       B-3


<PAGE>   50



         Once redeemed, the rights will terminate immediately and the only right
of the holders of the rights will be to receive the redemption price.

AMENDMENT OF RIGHTS AGREEMENT

         We may amend the Rights Agreement without the approval of the holders
of our common stock until the distribution date. After the distribution date, we
will only be able to amend the Rights Agreement in order to cure any ambiguity,
defect or inconsistency, to shorten or lengthen any time period, or to make
changes that do not adversely affect the interests of rights holders excluding
the interests of an Acquiring Person or their associates or affiliates. We may
only amend the time period governing redemption of the rights if the rights are
presently redeemable.

OTHER

         Until a right is exercised, the holder will have no rights as a
shareholder of ours as a result of the rights. This means, for example, that
until it is exercised, a right will not entitle its holder to vote or receive
dividends like one of our shareholders. The distribution of the rights will not
be taxable to shareholders or to us. However, shareholders may, depending upon
the circumstances, recognize taxable income in the event that the rights become
exercisable for units of Series C Preferred Stock, shares of Class A Common
Stock, other consideration or for common stock of an acquiring company.

         The discussion above describes the rights and the Rights Agreement but
is not complete, so you should read it together with the Rights Agreement, which
you may obtain from us upon request.

         As of December 2, 1999, 9,746,983 shares of our Class A Common Stock
were issued and outstanding and 4,787,131 shares of our Class B Common Stock
were issued and outstanding. Each share of our common stock outstanding on
December 16, 1999 will receive one right. As long as the rights are attached to
our common stock, we will issue one right for each share of our common stock
issued between the December 16, 1999 and the distribution date. A total of
398,000 shares of Series C Preferred Stock have been reserved for issuance upon
exercise of the rights, subject to adjustment.

         The units of Series C Preferred Stock that may be acquired upon
exercise of the rights will be nonredeemable and subordinate to any other shares
of preferred stock that may be issued by the Company.

         Each unit of Series C Preferred Stock will be entitled to receive,
when, as and if declared, dividends at the same rate as dividends are paid with
respect to the Class A Common Stock.

         In the event of liquidation, the holder of a unit of Series C Preferred
Stock will be entitled to share in any assets remaining ratably with the holders
of the Class A Common Stock.

                                       B-4


<PAGE>   51


         Each unit of Series C Preferred Stock issued to a holder of our common
stock will have one vote, voting together with our common stock.

         In the event of any merger, share exchange or other transaction in
which shares of our common stock are exchanged, each unit of Series C Preferred
Stock will be entitled to receive the per share amount paid in respect of each
share of Class A Common Stock.

         The rights of holders of the Series C Preferred Stock to dividends,
liquidation and voting, and in the event of mergers and share exchanges, are
protected by customary anti-dilution provisions.

         Because of the nature of the Series C Preferred Stock's dividend,
liquidation and voting rights, the economic value of one unit of Series C
Preferred Stock that may be acquired upon the exercise of each right should
approximate the economic value of one share of Class A Common Stock.

         The rights may have certain anti-takeover effects. The rights will
cause substantial dilution to a person or group that attempts to acquire us on
terms not approved by a majority of our board of directors unless the offer is
conditioned on a substantial number of rights being acquired. However, the
rights should not interfere with any merger or other business combination
approved by our board of directors since the rights may be redeemed by us at
$0.001 per right at any time on or prior to the tenth day following the
announcement that someone has become an Acquiring Person. Thus, the rights are
intended to encourage persons who may seek to acquire control of us to initiate
such an acquisition through negotiations with our board of directors. However,
the effect of the rights may be to discourage a third party from making a
partial tender offer or otherwise attempting to obtain a substantial equity
position in the equity securities of, or seeking to obtain control of, us. To
the extent any potential acquirers are deterred by the rights, the rights may
have the effect of preserving incumbent management in office.

                                  AMSURG CORP.

         Pursuant to the provisions of Section 48-16-102 of the Tennessee
Business Corporation Act, the undersigned corporation adopts the following
articles of amendment to its charter:

1.       The name of the Corporation is: AmSurg Corp.

2.       The text of each amendment adopted is:

         The first paragraph of Article 7 shall be deleted and replaced in its
         entirety with the following:

                  The aggregate number of shares of capital stock the
         Corporation is authorized to issue is 44,800,000 shares, of which
         35,000,000 shares shall be Class A Common Stock, no par value,
         4,800,000 shares shall be Class B Common Stock, no par value
         (collectively the "Common Stock"), and 5,000,000 shares shall be
         preferred stock, no par value (the "Preferred Stock") of which 500,000
         shares are designated as Series A Redeemable Preferred Stock, 416,666
         shares are designated as Series B Convertible Preferred Stock and
         398,000 are designated as Series C Junior Participating Preferred
         Stock. The Board of Directors may determine, in whole or in part, the
         preferences, limitations, and relative rights of any class of shares
         before the issuance of any shares of that class or one or more series
         within a class before the issuance of any shares within that series.

         The following shall be inserted following Article 7(3):

                  (4) Series C Junior Participating Preferred Stock. Pursuant to
         the authority vested in the Board of Directors in accordance with the
         provisions of this Article 7 of the Charter, the Board of Directors
         does hereby create, authorize and provide for the issuance of the
         Series C Junior Participating Preferred Stock out of the class of
         5,000,000 shares of Preferred Stock, having the voting powers,
         designation, relative, participating, optional and other special
         rights, preferences, and qualifications, limitations and restrictions
         thereof that are set forth as follows:

                  (a) Designation and Amount. The shares of such series shall be
         designated as Series C Junior Participating Preferred Stock ("Series C
         Preferred Stock") and the number of shares constituting such series
         shall be 398,000. Such number of shares may be adjusted by appropriate
         action of the Board of Directors.

                  (b) Dividends and Distributions. Subject to the prior and
         superior rights of the holders of any shares of any other series of
         Preferred Stock or any other shares of Preferred


<PAGE>   53



         Stock of the Corporation ranking prior and superior to the shares of
         Series C Preferred Stock with respect to dividends, each holder of one
         one-hundredth (1/100) of a share (a "Unit") of Series C Preferred Stock
         shall be entitled to receive, when, as and if declared by the Board of
         Directors out of funds legally available for that purpose, dividends at
         the same rate as dividends are paid with respect to the Common Stock.
         In the event that the Corporation shall at any time after November 19,
         1999 (the "Rights Dividend Declaration Date") (i) declare or pay any
         dividend on outstanding shares of Common Stock payable in shares of
         Common Stock; (ii) subdivide outstanding shares of Common Stock; or
         (iii) combine outstanding shares of Common Stock into a smaller number
         of shares, then in each such case the amount to which the holder of a
         Unit of Series C Preferred Stock was entitled immediately prior to such
         event pursuant to the preceding sentence shall be adjusted by
         multiplying such amount by a fraction the numerator of which shall be
         the number of shares of Common Stock that are outstanding immediately
         after such event and the denominator of which shall be the number of
         shares of Common Stock that were outstanding immediately prior to such
         event.

                  (c) Voting Rights. The holders of Units of Series C Preferred
         Stock shall have the following voting rights:

                           (i) Subject to the provision for adjustment
                  hereinafter set forth, each Unit of Series C Preferred Stock
                  shall entitle the holder thereof to one vote on all matters
                  submitted to a vote of the shareholders of the Corporation. In
                  the event the Corporation shall at any time after the Rights
                  Dividend Declaration Date (i) declare any dividend on
                  outstanding shares of Common Stock payable in shares of Common
                  Stock; (ii) subdivide outstanding shares of Common Stock; or
                  (iii) combine the outstanding shares of Common Stock into a
                  smaller number of shares, then in each such case the number of
                  votes per Unit to which holders of Units of Series C Preferred
                  Stock were entitled immediately prior to such event shall be
                  adjusted by multiplying such number by a fraction the
                  numerator of which shall be the number of shares of Common
                  Stock that are outstanding immediately after such event and
                  the denominator of which shall be the number of shares of
                  Common Stock that were outstanding immediately prior to such
                  event.

                           (ii) Except as otherwise provided herein or by law,
                  the holders of Units of Series C Preferred Stock and the
                  holders of shares of Common Stock shall vote together as one
                  class on all matters submitted to a vote of shareholders of
                  the Corporation.

                           (iii) Except as set forth herein or required by law,
                  holders of Units of Series C Preferred Stock shall have no
                  special voting rights and their consent shall not be required
                  (except to the extent they are entitled to vote with holders
                  of shares of Common Stock as set forth herein) for the taking
                  of any corporate action.

                  (d) Reacquired Shares. Any Units of Series C Preferred Stock
         purchased or otherwise acquired by the Corporation in any manner
         whatsoever shall be retired and cancelled promptly after the
         acquisition thereof. All such Units shall, upon their cancellation,
         become authorized but unissued Units of Series C Preferred Stock to be
         created by resolution or resolutions of the Board of Directors, subject
         to the conditions and restrictions on issuance set forth herein.

                  (e) Liquidation. Upon any liquidation, dissolution or winding
         up of the Corporation, whether voluntary or involuntary, the holders of
         Units of Series C Preferred Stock shall be entitled to share in any
         assets remaining ratably with the holders of the Common Stock. In the
         event the Corporation shall at any time after the Rights Dividend
         Declaration Date (i) increase by way of stock split or similar
         transaction the number of outstanding shares of Common Stock; (ii)
         subdivide the outstanding shares of Common Stock; or (iii) combine the
         outstanding shares of Common Stock into a smaller number of shares,
         then in each such case the aggregate amount to which holders of Units
         of Series C Preferred Stock were entitled prior to such event shall be
         adjusted by multiplying such amount by a fraction, the numerator of
         which shall be the number of shares of Common Stock that are
         outstanding immediately after such event and the denominator of which
         shall be the number of shares of Common Stock that were outstanding
         immediately prior to such event.

                  (f) Share Exchange, Merger, Etc. In case the Corporation shall
         enter into any share exchange, merger, combination or other transaction
         in which the shares of Common Stock are exchanged for or converted into
         other stock or securities, cash and/or any other property, then in any
         such case Units of Series C Preferred Stock shall at the same time be
         similarly exchanged for or converted into an amount per Unit (subject
         to the provision for adjustment hereinafter set forth) equal to the
         aggregate amount of stock, securities, cash and/or any other property
         (payable in kind), as the case may be, into which or for which each
         share of Common Stock is converted or exchanged. In the event the
         Corporation shall at any time after the Rights Dividend Declaration
         Date (i) declare any dividend on outstanding shares of Common Stock
         payable in shares of Common Stock; (ii) subdivide outstanding shares of
         Common Stock; or (iii) combine outstanding shares of Common Stock into
         a smaller number of shares, then in each such case the amount set forth
         in the immediately preceding sentence with respect to the exchange or
         conversion of Units of Series C Preferred Stock shall be adjusted by
         multiplying such amount by a fraction the numerator of which shall be
         the number of shares of Common Stock that are outstanding immediately
         after such event and the denominator of which shall be the number of
         shares of Common Stock that were outstanding immediately prior to such
         event.

                  (g) Redemption. The Units of Series C Preferred Stock shall
         not be redeemable at the option of the Corporation or any holder
         thereof. Notwithstanding the foregoing sentence of this Section, the
         Corporation may acquire Units of Series C Preferred Stock in any other
         manner permitted by law and the Charter or Bylaws of the Corporation.

                  (h) Ranking. The Units of Series C Preferred Stock shall rank
         junior to all other series of the Preferred Stock and to any other
         class of Preferred Stock that hereafter may be issued by the
         Corporation as to the payment of dividends and the distribution of
         assets, unless the terms of any such series or class shall provide
         otherwise.

                  (i) Amendment. The Charter, including without limitation the
         provisions hereof, shall not hereafter be amended, either directly or
         indirectly, or through merger or share exchange with another
         corporation, in any manner that would alter or change the powers,
         preferences or special rights of the Series C Preferred Stock so as to
         affect the holders thereof adversely without the affirmative vote of
         the holders of a majority or more of the outstanding Units of Series C
         Preferred Stock, voting separately as a class.

                  (j) Fractional Shares. The Series C Preferred Stock may be
         issued in Units or other fractions of a share, which Units or fractions
         shall entitle the holder, in proportion to such holder's fractional
         shares, to exercise voting rights, receive dividends, participate in
         distributions and to have the benefit of all other rights of holders of
         Series C Preferred Stock.

3.       The amendment was duly adopted on November 19, 1999 by the Board of
         Directors at a duly called meeting of the Board of Directors. The
         amendment was adopted without shareholder action since shareholder
         action was not required.
