                  THIS AMENDED AND RESTATED RIGHTS AGREEMENT, dated as of
August 1, 2000 (the "Agreement"), between SouthTrust Corporation, a Delaware

                              W I T N E S S E T H:

                  WHEREAS, on February 22, 1989, the Board of Directors of the
Company authorized and declared a dividend distribution of one right for each
share of common stock, par value $2.50 per share, of the Company, each Right
initially representing the right to purchase one one-hundredth of a share of
Series A Junior Participating Preferred Stock of the Company having the rights,
powers and preferences set forth in the form of Certificate of Designation,
Preferences and Rights of Series A Junior Participating Preferred Stock attached
as Exhibit A to that certain Rights Agreement, dated February 22, 1989, by and
between the Company and Mellon Bank, N.A. (the "1989 Rights Plan"); and

                  WHEREAS, the 1989 Rights Plan terminated by its own terms at
the Close of Business on February 22, 1999, and, at a meeting on December 16,
1998, the Board of Directors of the Company deemed it to be in the best interest
of the Company and its stockholders, upon the termination of the 1989 Rights
Plan, to enter into that certain Rights Agreement dated as of January 12, 1999
and effective at the Close of Business (as defined herein) on February 22, 1999
by and between the Company and ChaseMellon Shareholder Services, L.L.C. (the
"1999 Rights Plan"); and

                  WHEREAS, on December 16, 1998 (the "Rights Dividend
Declaration Date"), the Board of Directors of the Company authorized and
declared a dividend distribution of one Right for each share of common stock,
par value $2.50 per share, of the Company (the "Common Stock") outstanding at
the Close of Business on February 22, 1999 (the "Record Date"), and has
authorized the issuance of one Right (as such number may hereinafter be adjusted
pursuant to the provisions of Section 11(p) hereof) for each share of Common
Stock of the Company issued between the Record Date (whether originally issued
or delivered from the Company's treasury) and the Distribution Date, each Right
initially representing the right to purchase one one-hundredth of a share of

of Resolutions attached hereto as Exhibit A, upon the terms and subject to the
conditions hereinafter set forth (the "Rights"); and

                  WHEREAS, the Company has determined that it is in the best
interests of the Company and its stockholders to remove ChaseMellon Shareholder
Services, L.L.C. ("ChaseMellon") as the Rights Agent under the 1999 Rights Plan,
and to substitute in their place and stead, American Stock Transfer & Trust
Company, and to amend and restate the 1999 Rights Plan to reflect such removal
and substitution.

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


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

                           (a)      "Acquiring Person" shall mean any Person who
or which, together with all Affiliates and Associates of such Person, shall be
the Beneficial Owner of 15% or more of the shares of Common Stock then
outstanding, but shall not include (i) the Company, (ii) any Subsidiary of the
Company, (iii) any employee benefit plan of the Company or of any Subsidiary of
the Company, or (iv) any Person or entity organized, appointed or established by
the Company for or pursuant to the terms of any such plan; provided, however,
that if the Board of Directors of the Company determines in good faith that a
Person who would otherwise be an "Acquiring Person" has become such
inadvertently (including, without limitation, because (i) such Person was
unaware that it beneficially owned a percentage of Common Stock that would
otherwise cause such Person to be an "Acquiring Person" or (ii) such Person was
aware of the extent of its Beneficial Ownership of Common Stock but had no
actual knowledge of the consequences of such Beneficial Ownership under this
Rights Agreement) and without any intention of changing or influencing control
of the Company, and such Person, as promptly as practicable divested or divests
himself or itself of Beneficial Ownership of a sufficient number of shares of
Common Stock so that such Person would no longer be an Acquiring Person, then
such Person shall not be deemed to be or to have become 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 shares of
Common Stock by the Company which, by reducing the number of shares outstanding,
increases the proportionate number of shares beneficially owned by such Person
to 15% or more of the shares of Common Stock then outstanding; provided,
however, that if a Person shall become the Beneficial Owner of 15% or more of
the shares of Common Stock then outstanding by reason of such share acquisitions
by the Company and thereafter become the Beneficial Owner of any additional
shares of Common Stock, then such Person shall be deemed to be an "Acquiring
Person" unless, upon the consummation of the acquisition of such additional
shares of Common Stock, such Person does not own 15% or more of the shares of
Common Stock then outstanding. The phrase "then outstanding," when used with
reference to a Person's Beneficial Ownership of securities of the Company, shall
mean the number of such securities then issued and outstanding together with the
number of such securities not then actually issued and outstanding which such
Person would be deemed to own beneficially hereunder.

                           (b)      "Act" shall mean the Securities Act of 1933,
as amended, and any subsequent federal statute succeeding to the provisions
thereof.

                           (c)      "Adjustment Shares" shall have the meaning
set forth in Section 11(a)(ii) hereof.

                           (d)      "Adverse Person" shall mean any person
declared to be an Adverse Person by the Board upon determination that the
criteria set forth in Section 11(a)(ii)(B) apply to such person.


                                        2

<PAGE>   6



                           (e)      "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 and in
effect on the date of this Agreement (the "Exchange Act").

                           (f)      "Agreement" shall mean this Rights Agreement
as originally executed or as it may from time to time be supplemented or amended
pursuant to the applicable provisions hereof.

                           (g)      A Person shall be deemed the "Beneficial
Owner" of, and shall be deemed to "beneficially own," any securities:

                                    (i)     which such Person or any of such
         Person's Affiliates or Associates, directly or indirectly, has the
         right to acquire (whether such right is exercisable immediately or only
         after the passage of time) pursuant to any agreement, arrangement, or
         understanding (whether or not in writing) or upon the exercise of
         conversion rights, exchange rights, rights (other than these Rights),
         warrants or options, or otherwise; provided, however, that a Person
         shall not be deemed the "Beneficial Owner" of, or to "beneficially
         own," (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 are accepted for purchase or exchange,
         or (B) securities issuable upon exercise of Rights at any time prior to
         the occurrence of a Triggering Event, or (C) securities issuable upon
         exercise of Rights from and after the occurrence of a Triggering Event
         which Rights were acquired by such Person or any of such Person's
         Affiliates or Associates prior to the Distribution Date or pursuant to
         Section 3(a) or Section 22 hereof (the "Original Rights") or pursuant
         to Section 11(i) hereof in connection with an adjustment made with
         respect to any Original Rights;

                                    (ii)     which such Person or any of such
         Person's Affiliates or Associates, directly or indirectly, has the
         right to vote or dispose of or has "beneficial ownership" of (as
         determined pursuant to Rule 13d-3 of the General Rules and Regulations
         under the Exchange Act), including pursuant to any agreement,
         arrangement or understanding, whether or not in writing; provided,
         however, that a Person shall not be deemed the "Beneficial Owner" of,
         or to "beneficially own," any security under this subparagraph (ii) 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 public proxy or
         consent solicitation made pursuant to, and in accordance with, the
         applicable provisions of the General Rules and Regulations under the
         Exchange Act, and (B) is not also then reportable by such Person on
         Schedule 13D under the Exchange Act (or any comparable or successor
         report); or

                                    (iii)    which are beneficially owned,
         directly or indirectly, by any other Person (or any Affiliate or
         Associate thereof) 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 (ii) of this paragraph (g))

         however, that nothing in this paragraph (g) shall cause a person
         engaged in business as an underwriter of securities to be the
         "Beneficial Owner" of, or to "beneficially own," any securities
         acquired through such person's participation in good faith in a firm
         commitment underwriting with the Company until the expiration of such

appointment. The Company may from time to time appoint such co-Rights Agents as
it may deem necessary or desirable. The Rights Agent shall have no duty to
supervise, and in no event shall be liable for, the acts or omissions of any
such co-Rights Agent.

                  Section 3.        Issuance of Rights Certificates.

                           (a)      Until the earliest to occur of (i) the Close
of Business on the tenth (10th) day after the Stock Acquisition Date (or, if the
tenth (10th) day after the Stock Acquisition Date occurs before the Record Date,
the Close of Business on the Record Date), or (ii) the Close of Business on the
tenth (10th) Business Day (or such later date as may be determined by action of
the Board of Directors prior to such time as any Person becomes an Acquiring
Person) after the date of the commencement by any Person (other than the
Company, any Subsidiary of the Company, any employee benefit plan of the Company
or of any Subsidiary of the Company or any entity organized, appointed or
established by the Company for or pursuant to the terms of any such employee
benefit plan) of, or of the first public announcement of the intention of any
Person (other than the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or of any Subsidiary of the Company or any entity
organized, appointed or established by the Company for or pursuant to the terms
of any such employee benefit plan) to commence, a tender or exchange offer the
consummation of which would result in any Person becoming the Beneficial Owner
of Common Shares aggregating 15% or more of the then outstanding Common Shares,
or (iii) the Close of Business on the tenth day after the Board determines,
pursuant to the criteria set forth in Section 11(a)(ii)(B) hereof, that a Person
is an Adverse Person (the earliest to occur of the events described in clauses
(i), (ii) and (iii) of this paragraph (a) being herein referred to as the
"Distribution Date"), (x) the Rights will be evidenced (subject to the
provisions of paragraph (b) of this Section 3) by the certificates for the
Common Stock registered in the names of the holders of the Common Stock (which
certificates for Common Stock shall be deemed also to be certificates for
Rights) and not by separate certificates, and (y) the Rights will be
transferrable only in connection with the transfer of the underlying shares of
Common Stock (including a transfer to the Company). As soon as practicable after
the Distribution Date, the Company will prepare and execute, the Rights Agent
will countersign, and the Company will send or cause to be sent (and the Rights
Agent will, if requested and provided with all necessary information, send) by
first-class, insured, postage prepaid mail, to each record holder of the 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 rights
certificates, in substantially the form of Exhibit B hereto (the "Rights
Certificates"), evidencing one Right for each share of Common Stock so held,
subject to adjustment as provided herein. In the event that an adjustment in the
number of Rights per share of 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)      On the Record Date or as promptly as
practicable following the Record Date, the Company will send a copy of a Summary
of Rights, in substantially the form attached hereto as Exhibit C (the "Summary
of Rights"), by first-class, postage prepaid mail, to each record holder of the
Common Stock as of the Close of Business on the Record Date (other than any
Acquiring Person or any Associate or Affiliate of any Acquiring Person), at the
address of such holder shown on the records of the Company. With respect to
certificates for the Common Stock outstanding as of the Record Date, until the
Distribution Date, the Rights will be evidenced by such


                                       7
<PAGE>   11

certificates for the Common Stock and the registered holders of the Common Stock
shall also be the registered holders of the associated Rights. Until the earlier
of the Distribution Date or the Expiration Date, the transfer of any
certificates representing shares of Common Stock in respect of which Rights have
been issued shall also constitute the transfer of the Rights associated with
such shares of Common Stock.

                           (c)      Rights shall be issued in respect of all
shares of Common Stock which are issued or disposed of (whether originally
issued or from the Company's treasury) after the Record Date but prior to the
earlier of the Distribution Date or the Expiration Date. Certificates
representing such shares of Common Stock shall also be deemed to be certificates
for Rights, and all certificates issued after the date of this Agreement
representing shares of Common Stock 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 SouthTrust Corporation (the "Company") and
                  the Rights Agent, dated as of January 12, 1999 and effective
                  at the close of business on February 22, 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
                  offices of the Company. Under certain circumstances, as set
                  forth in the Rights Agreement, such Rights will be evidenced
                  by separate certificates and will no longer be evidenced by
                  this certificate. The Company will mail to the holder of this
                  certificate a copy of the Rights Agreement, 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, an
                  Adverse 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 and will no longer be
                  transferable.

                  With respect to such certificates containing the foregoing
legend, until the earlier of (i) the Distribution Date or (ii) the Expiration
Date, the Rights associated with the Common Stock represented by such
certificates shall be evidenced by such certificates alone and registered
holders of Common Stock shall also be 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 Common Stock represented by such
certificates. In the event that the Company purchases or acquires any Common
Shares after the Record Date but prior to the Distribution Date, any Rights
associated with such Common Shares shall be deemed canceled and retired so that
the Company shall not be entitled to exercise any Rights associated with the
Common Shares which are no longer outstanding.

                  Section 4.        Form of Rights Certificates.


                                       8
<PAGE>   12

                           (a)      The Rights Certificates (and the forms of
election to purchase and of assignment to be printed on the reverse thereof)
shall each be substantially in the form set forth in Exhibit B hereto and may
have such marks of identification or designation and such legends, summaries or
endorsements printed thereon as the Company may deem appropriate, which do not
affect the duties or responsibilities of the Rights Agent and as are not
inconsistent with the provisions of this Agreement, or as may be required to
comply with any applicable law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange 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 one one-hundredths
of a share of Preferred Stock as shall be set forth therein at the price set
forth therein (such exercise price per one one-hundredth of a share being called
herein the "Purchase Price"), but the amount and type of securities purchasable
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 to
Section 3(a) or Section 22 hereof that represents Rights beneficially owned by:
(i) an Acquiring Person, an Adverse Person, or any Associate or Affiliate of any
Acquiring Person or an Adverse Person, (ii) a transferee of an Acquiring Person
or an Adverse Person (or of any such Associate or Affiliate) who becomes a
transferee after the Acquiring Person or the Adverse Person becomes such, or
(iii) a transferee of an Acquiring Person or an Adverse Person (or of any such
Associate or Affiliate) who becomes a transferee prior to or concurrently with
the Acquiring Person or the Adverse Person becoming such and receives such
Rights pursuant to either (A) a transfer (whether or not for consideration) from
the Acquiring Person or the Adverse Person to holders of equity interests in
such Acquiring Person or Adverse Person or to any Person with whom such
Acquiring Person or Adverse Person has any continuing agreement, arrangement or
understanding regarding the transferred Rights or (B) a transfer which the Board
has determined is part of a plan, arrangement or understanding which has as a
primary purpose or effect avoidance of the provisions of Section 7(e) hereof,
and any Rights Certificate issued pursuant to Section 6 or Section 11 hereof,
upon transfer, exchange, replacement or adjustment of any other Rights
Certificate referred to in this sentence, shall 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 Adverse Person or any
                      Affiliate or Associate of an Acquiring Person or
                      Adverse 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.


                                       9
<PAGE>   13

                           (a)      The Rights Certificates shall be executed on
behalf of the Company by its Chairman of the Board, its President or any Vice
President, either manually or by facsimile signature, and shall have affixed
thereto the Company's seal or a facsimile thereof which shall be attested by the
Secretary or an Assistant Secretary of the Company, either manually or by
facsimile signature. The Rights Certificates shall be manually countersigned by
the Rights Agent and shall not be valid for any purpose unless so countersigned.
In case any officer of the Company who shall have signed any of the Rights
Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Rights Certificates nevertheless may be countersigned by the Rights Agent
and issued and delivered by the Company with the same force and effect as though
the person who signed such Rights Certificates had not ceased to be such officer
of the Company; and any Rights Certificates may be signed on behalf of the
Company by any person who, at the actual date of the execution of such Rights
Certificate, shall be a proper officer of the Company to sign such Rights
Certificate, although at the date of the execution of this Rights Agreement any
such person was not such an officer.

                           (b)      Following the Distribution Date and receipt
by the Rights Agent of all necessary information, the Rights Agent will keep or
cause to be kept, at its principal office or offices designated as the
appropriate place 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 names and addresses of the respective
holders of the Rights Certificates, the number of Rights evidenced on its face
by each of the Rights Certificates and the date of each of the Rights
Certificates.

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

                           (a)      Subject to the provisions of Section 4(b),
Section 7(e) and Section 14 hereof, at any time after the Close of Business on
the Distribution Date, and at or prior to the Close of Business on the
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 one one-hundredths
of a share of Preferred Stock (or, following a Triggering Event, Common Stock,
other securities, cash or other assets, as the case may be) as the Rights
Certificate or Certificates surrendered then entitled such holder (or former
holder in the case of a transfer) 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 principal office or offices 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
and signed the certificate contained 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) or
Affiliates or Associates thereof as the Company shall reasonably request.
Thereupon the Rights Agent shall, subject to 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.
The Company may require payment of a


                                       10
<PAGE>   14

sum sufficient to cover any tax or charge that may be imposed in connection with
any transfer, split up, combination or exchange of Rights Certificates. The
Rights Agent shall have no duty or obligation under this Section unless and
until it is satisfied that all such taxes and/or charges have been paid.

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

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

                           (a)      Subject to Section 7(e) hereof, the
registered holder of any Rights Certificate may exercise the Rights evidenced
thereby (except as otherwise provided herein including, without limitation, the
restrictions on exercisability set forth in Section 9(c), Section 11(a)(iii),
Section 23(a) and Section 24(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 certificate on the reverse side thereof duly and
properly executed, to the Rights Agent at the principal office or offices of the
Rights Agent designated for such purpose, together with payment of the aggregate
Purchase Price with respect to the total number of one one-hundredth of a share
of Preferred Stock (or other securities, cash or other assets, as the case may
be) as to which such surrendered Rights are then exercisable, at or prior to the
earliest to occur of (i) the Final Expiration Date, (ii) the time at which the
Rights are redeemed as provided in Section 23 hereof or the time at which the
Rights are exchanged as provided in Section 24 hereof or (iii) the expiration of
the Rights pursuant to Section 13(d) (the earliest to occur of the events
described in clauses (i), (ii) and (iii) of this paragraph (a) herein being
referred to as the "Expiration Date").

                           (b)      The Purchase Price for each one
one-hundredth of a share of Preferred Stock (or other securities, cash or other
assets, as the case may be) pursuant to the exercise of a Right shall initially
be $150.00, and shall be subject to adjustment from time to time as provided in
Sections 11 and 13(a) hereof and shall be payable in accordance with paragraph
(c) below.

                           (c)      Upon receipt of a Rights Certificate
representing exercisable Rights, with the form of election to purchase and the
certificate duly and properly executed, accompanied by payment, with respect to
each Right so exercised, of the Purchase Price per one one-hundredth of a share
of Preferred Stock (or other securities, cash or other assets, as the case may
be) to be purchased as set forth below and an amount equal to any applicable tax
or charge, the Rights Agent shall, subject to Section 20(k) hereof, thereupon
promptly (i)(A) requisition from any transfer agent of the shares of Preferred
Stock (or make available, if the Rights Agent is the transfer agent for such
shares) certificates for the total number of one one-hundredths of a share of
Preferred Stock to be purchased, and the Company hereby irrevocably authorizes
its transfer agent to comply with all such


                                       11
<PAGE>   15

requests, or (B) if the Company shall have elected to deposit the total number
of shares of Preferred Stock issuable upon exercise of the Rights hereunder with
a depositary agent, requisition from the depositary agent of depositary receipts
representing such number of one one-hundredths of a share of Preferred Stock as
are to be purchased (in which case certificates for the shares of Preferred
Stock represented by such receipts shall be deposited by the transfer agent with
the depositary agent), 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 certificates or 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. 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 check, cashier's check or money
order payable to the order of the Company. In the event that the Company is
obligated to issue other securities (including Common Stock) 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 other securities, cash
and/or other property are available for distribution by the Rights Agent, if and
when appropriate.

                           (d)      Except as otherwise provided herein, in case
the registered holder of any Rights Certificate shall exercise less than all the
Rights evidenced thereby, a new Rights Certificate evidencing Rights equivalent
to the Rights remaining unexercised shall be issued by the Rights Agent and
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, 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, an Adverse
Person or an Associate or Affiliate of an Acquiring Person or an Adverse Person,
(ii) a transferee of an Acquiring Person or Adverse Person (or of any such
Associate or Affiliate) who becomes a transferee after such Acquiring Person or
Adverse Person becomes such, or (iii) a transferee of any such Acquiring Person
or Adverse Person (or of any such Associate or Affiliate) who becomes a
transferee prior to or concurrently with such Acquiring Person or Adverse Person
becoming such and receives such rights pursuant to either (A) a transfer
(whether or not for consideration) from such Acquiring Person or Adverse Person
to holders of equity interests in such Acquiring Person or Adverse Person or to
any Person with whom such Acquiring Person or Adverse Person has any continuing
agreement, arrangement or understanding regarding the transferred Rights or (B)
a transfer which the Board of Directors of the Company has determined is part of
a plan, arrangement or understanding which has as a primary purpose or effect
the avoidance of this Section 7(e), shall become null, void and nontransferable
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 insure
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 Certificates or other
Person as a result of its failure to make any determinations with respect to an
Acquiring Person or Adverse Person or any of their respective Affiliates,
Associates or transferees hereunder.


                                       12
<PAGE>   16

                           (f)      Notwithstanding anything contained in this
Agreement 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 as set forth in this Section 7 unless such
registered holder shall have (i) completed and signed the certificate contained
in 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) or
Affiliates or Associates thereof as the Company or the Rights Agent 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 any of the provisions of this Agreement. The Company shall deliver
to the Rights Agent for cancellation and retirement, and the Rights Agent shall
so cancel and retire, any other Rights Certificate purchased or 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 covenants and agrees that it
will cause to be reserved and kept available out of its authorized and unissued
shares of Preferred Stock (and, following the occurrence of a Triggering Event,
out of its authorized and unissued shares of Common Stock and/or other
securities or out of its authorized and issued shares held in its treasury), the
number of shares of Preferred Stock (and, following the occurrence of a
Triggering Event, Common Stock and/or other securities) that, as provided in
this Agreement, including Section 11(a)(iii) hereof, will be sufficient to
permit the exercise in full of all outstanding Rights.

                           (b)      So long as the shares of Preferred Stock
(and, following the occurrence of a Triggering Event, Common Stock and/or other
securities) issuable and deliverable upon the exercise of the Rights are to be
listed on any national securities exchange, the Company shall use its best
efforts to cause, from and after such time as the Rights become exercisable, all
shares reserved for such issuance to be listed on such exchange upon official
notice of issuance upon such exercise.

                           (c)      The Company shall use its best efforts to
(i) file, as soon as practicable following the earliest date after the first
occurrence of a Section 11(a)(ii) Event on which the consideration to be
delivered by the Company upon exercise of the Rights has been determined in
accordance with Section 11(a)(iii) hereof, or at such time as is required by law
following the Distribution Date, a registration statement under the Act, with
respect to the securities purchasable upon exercise of the Rights on an
appropriate form, (ii) cause such registration statement to become effective as
soon as practicable after such filing, and (iii) cause such registration
statement to remain


                                       13
<PAGE>   17

effective (with a prospectus at all times meeting the requirements of the Act)
until the earlier of (A) the date as of which the Rights are no longer
exercisable for such securities, and (B) the date of the expiration of the
Rights. The Company will also take such action as may be appropriate under, or
to insure compliance with, the securities or "blue sky" laws of the various
states in connection with the exercisability of the Rights. The Company may
temporarily suspend, for a period of time not to exceed ninety (90) days after
the date set forth in clause (i) of the first sentence of this Section 9(c), the
exercisability of the Rights in order to prepare and file such registration
statement and permit it to become effective. Upon any such suspension, the
Company shall issue a public announcement stating that the exercisability of the
Rights has been temporarily suspended, as well as a public announcement at such
time as the suspension is no longer in effect, with prompt notice thereof to the
Rights Agent. In addition, if the Company shall determine that a registration
statement is required following the Distribution Date, the Company may
temporarily suspend the exercisability of the Rights until such time as a
registration statement has been declared effective. Notwithstanding any
provision of this Agreement to the contrary, the Rights shall not be exercisable
in any jurisdiction if the requisite qualification in such jurisdiction shall
not have been obtained, the exercise thereof shall not be permitted under
applicable law or a registration statement shall not have been declared
effective.

                           (d)      The Company covenants and agrees that it
will take all such action as may be necessary to ensure that all one
one-hundredths of a share of Preferred Stock (and, following the occurrence of a
Triggering Event, Common Stock and/or other securities) delivered upon exercise
of Rights shall, at the time of delivery of the certificates for such shares
(subject to payment of the Purchase Price), be duly and validly authorized and
issued and fully paid and nonassessable.

                           (e)      The Company further covenants and agrees
that it will pay when due and payable any and all taxes and charges which may be
payable in respect of the issuance or delivery of the Rights Certificates and of
any certificates for a number of one one-hundredths of a share of Preferred
Stock (or Common Stock and/or other securities, as the case may be ) upon the
exercise of Rights. The Company shall not, however, be required to pay any tax
or charge which may be payable in respect of any transfer or delivery of Rights
Certificates to a Person other than, or the issuance or delivery of a number of
one one-hundredths of a share of Preferred Stock (or Common Stock and/or other
securities, as the case may be) in respect of a name other than that of, the
registered holder of the Rights Certificates evidencing Rights surrendered for
exercise or to issue or deliver any certificates for a number of one
one-hundredths of a share of Preferred Stock (or Common Stock and/or other
securities, as the case may be) in a name other than that of the registered
holder upon the exercise of any Rights until such tax or charge shall have been
paid (any such tax or charge 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 or charge is due.

                  Section 10.       Preferred Stock Record Date. Each person in
whose name any certificate for a number of one one-hundredths of a share of
Preferred Stock (or Common Stock and/or other securities, as the case may be) is
issued upon the exercise of Rights shall for all purposes be deemed to have
become the holder of record of such fractional shares of Preferred Stock (or
Common Stock and/or other securities, as the case may be) represented thereby
on, and such


                                       14
<PAGE>   18

certificate shall be dated the date upon which the Rights Certificate evidencing
such Rights was duly surrendered and payment of the Purchase Price (and all
applicable taxes or charges) was made; provided, however, that if the date of
such surrender and payment is a date upon which the Preferred Stock (or Common
Stock and/or other securities, as the case may be) transfer books of the Company
are closed, such Person shall be deemed to have become the record holder of such
shares (fractional or otherwise) on, and such certificate shall be dated, the
next succeeding Business Day on which the Preferred Stock (or Common Stock
and/or other securities, as the case may be) 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 stockholder of the
Company with respect to shares for which the Rights shall be exercisable,
including, without limitation, the right to vote, to receive dividends or other
distributions or to exercise preemptive rights, if any, 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
shares covered by each Right and the number of Rights outstanding are subject to
adjustment from time to time as provided in this Section 11.

                           (a)(i)   In the event the Company shall at any time
         after the date of this 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 consolidation or merger
         in which the Company is the continuing or surviving corporation),
         except as otherwise provided in this Section 11(a) and in Section 7(e)
         hereof, 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,
         shall be proportionately adjusted so that the holder of any Right
         exercised after such time shall be entitled to receive, upon payment of
         the aggregate adjusted Purchase Price then in effect necessary to
         exercise a Right in full, 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 and at a time
         when the Preferred Stock (or other capital stock, as the case may be)
         transfer books of the Company were open, he would have owned upon such
         exercise and 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.

                           (ii)     Subject to Section 24, in the event:

                                    (A)      any Person shall become an
                  Acquiring Person, unless the event causing such Person to
                  become an Acquiring Person is a transaction set forth in
                  Section 13(a) hereof or is an acquisition of shares of Common
                  Stock pursuant to a tender offer, or an


                                       15
<PAGE>   19

                  exchange offer for all outstanding shares of Common Stock of
                  the Company at a price and on terms determined by at least a
                  majority of the members of the Board of Directors of the
                  Company who are not officers of the Company and who are not
                  representatives, nominees, Affiliates or Associates of an
                  Acquiring Person or an Adverse Person, after receiving advice
                  from one or more investment banking firms, to be (a) at a
                  price which is fair to stockholders (taking into account all
                  factors which such members of the Board of Directors deem
                  relevant, including, without limitation, prices which could
                  reasonably be achieved if the Company or its assets were sold
                  on an orderly basis designed to realize maximum value) and (b)
                  otherwise in the best interests of the Company and its
                  stockholders, or

                           (B)      the Board shall declare any Person to be an
                  Adverse Person, upon a determination by the Board that such
                  Person, alone or together with its Affiliates and Associates,
                  has, at any time after the Rights Dividend Declaration Date,
                  become the Beneficial Owner of an amount of Common Stock which
                  the Board determines to be substantial (which amount shall in
                  no event be less than 10% of the shares of Common Stock then
                  outstanding) and a determination by a majority of the Board
                  who are not officers of the Company, after reasonable inquiry
                  and investigation, including consultation with such Persons as
                  such directors shall deem appropriate, that (a) such
                  Beneficial Ownership by such Person is intended to cause, is
                  reasonably likely to cause, or will cause the Company to
                  repurchase the Common Stock beneficially owned by such Person
                  or to take action or enter into a transaction or series of
                  transactions intended to provide such Person with short-term
                  financial gain under circumstances where the Board determines
                  that the best long-term interests of the Company and its
                  stockholders would not be served by taking such action or
                  entering into such transaction or series of transactions at
                  that time or (b) such Beneficial Ownership is causing or
                  reasonably likely to cause a material adverse impact
                  (including, but not limited to, by jeopardizing the Company's
                  or its Subsidiaries' authorizations from, or relationships
                  with, federal or state regulators, or impairment of the
                  Company's relationships with customers or its ability to
                  maintain its financial or competitive position) on the
                  business or prospects of the Company to the detriment of the
                  Company's stockholders,

then, promptly following the occurrence of any event described in Section
11(a)(ii)(A) or Section 11(a)(ii)(B) hereof, proper provision shall be made so
that each holder of a Right (except as provided below and in Section 7(e)
hereof) shall thereafter have the right to receive, upon exercise thereof at the
then current Purchase Price in accordance with the terms of this Agreement, in
lieu of a number


                                       16
<PAGE>   20

of one one-hundredths of a share of Preferred Stock, such number of shares of
Common Stock of the Company as shall equal the result obtained by (x)
multiplying the then current Purchase Price by the then number of one
one-hundredths of a share of Preferred Stock for which a Right was exercisable
immediately prior to the first occurrence of a Section 11(a)(ii) Event, and (y)
dividing that product (which, following such first occurrence, shall thereafter
be referred to as the "Purchase Price" for each Right and for all purposes of
this Agreement) by 50% of the current market price per share of Common Stock on
the date of such first occurrence (such number of shares being referred to as
the "Adjustment Shares").

                           (iii)    In the event that the number of shares of
Common Stock which are authorized by the Company's Restated Certificate of
Incorporation but not outstanding or reserved for issuance for purposes other
than upon exercise of the Rights is not sufficient to permit the exercise in
full of the Rights in accordance with the foregoing subparagraph (ii) of this
Section 11(a), or in the event that the Board of Directors of the Company
determines to issue Common Stock Equivalents (as defined below) or otherwise to
make alternative provision upon exercise of the Rights, the Company 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 referred to as the "Spread"), and (B) with respect to each Right,
make adequate provision to substitute for the Adjustment Shares, upon payment of
the applicable Purchase Price, if appropriate, (1) cash, (2) a reduction in the
Purchase Price, (3) Common Stock or other equity securities of the Company
(including, without limitation, shares, or units of shares, of preferred stock
which the Board has deemed to have the same value as shares of Common Stock
(such shares of preferred stock being referred to as "Common 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 based upon
the advice of a investment banking firm selected by the Board; provided,
however, if the Company shall not have made adequate provision to deliver value
pursuant to clause (B) above within thirty (30) 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 Common
Stock (to the extent available) and then, if necessary, cash, which shares
and/or cash have an aggregate value equal to the Spread. If the Board shall
determine in good faith that it is likely that sufficient additional shares of
Common Stock could be authorized for issuance upon exercise in full of the
Rights, the thirty (30) day period set forth above may be extended to the extent
necessary, but not more than ninety (90) days after the Section 11(a)(ii)
Trigger Date, in order that the Company may seek stockholder approval for the
authorization of such additional shares (such period, as it may be extended,
being referred to herein as the "Substitution Period"). To the extent that the
Company


                                       17
<PAGE>   21

         determines that some action need be taken pursuant to the first and/or
         second sentences of this Section 11(a)(iii), the Company (x) shall
         provide, subject to Section 7(e) hereof, that such action shall apply
         uniformly to all outstanding Rights, and (y) may suspend the
         exercisability of the Rights until the expiration of the Substitution
         Period in order to seek any authorization of additional shares and/or
         to decide the appropriate form of distribution to be made pursuant to
         such first sentence and to determine the value thereof. In the event of
         any such suspension, the Company shall issue a public announcement
         stating that the exercisability of the Rights has been temporarily
         suspended, as well as a public announcement at such time as the
         suspension is no longer in effect, in each case, with prompt notice
         thereof to the Rights Agent. For purposes of this Section 11(a)(iii),
         the value of the Common Stock shall be the current market price per
         share of the Common Stock on the Section 11(a)(ii) Trigger Date and the
         value of any "Common Stock Equivalent" shall be deemed to have the same
         value as the Common Stock on such date.

                           (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 (45) calendar days after such record date) Preferred Stock (or shares
having the same rights, privileges and preferences as the 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 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 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, 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 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 Preferred Stock (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation) of evidences of indebtedness, cash


                                       18
<PAGE>   22

(other than a regular quarterly cash dividend out of the earnings or retained
earnings of the Company), assets (other than a dividend payable in 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 per share of Preferred Stock on such record date, less the
fair market value (as determined in good faith by the Board, whose determination
shall be described in a statement filed with the Rights Agent) 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 per share of Preferred
Stock. Such adjustments shall be made successively whenever such a record date
is fixed, and in the event that such distribution is not so made, the Purchase
Price shall 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, other than computations made pursuant to Section 11(a)(iii)
         hereof, the "current market price" per share of Common Stock on any
         date shall be deemed to be the average of the daily closing prices per
         share of such Common Stock for thirty (30) consecutive Trading Days
         immediately prior to such date, and for purposes of computations made
         pursuant to Section 11(a)(iii) hereof, the "current market price" per
         share of Common Stock on any date shall be deemed to be the average of
         the daily closing prices per share of such Common Stock for the ten
         (10) consecutive Trading Days immediately following but not including
         such date; provided, however, that in the event that the current market
         price per share of the Common Stock is determined during a period
         following the announcement by the issuer of such Common Stock of (A) a
         dividend or distribution on such Common Stock payable in shares of such
         Common Stock or securities convertible into shares of such Common Stock
         (other than the Rights), or (B) any subdivision, combination or
         reclassification of such Common Stock, and prior to the expiration of
         the requisite thirty (30) Trading Day or ten (10) Trading Day period,
         as set forth above, after but not including the ex-dividend date for
         such dividend or distribution, or the record date for such subdivision,
         or combination or reclassification, then, and in each such case, the
         "current market price" shall be appropriately adjusted to take into
         account ex-dividend trading. The closing price for each day shall be
         the last sale price, regular way, or, in case no such sale takes place
         on such day, the average of the closing bid and asked prices, regular
         way, in either case as reported in the principal consolidated
         transaction reporting system with respect to securities listed or
         admitted to trading on the New York Stock Exchange or, if the shares of
         Common Stock are not listed or admitted to trading on the New York
         Stock Exchange, as reported in the principal consolidated transaction
         reporting system with respect to securities listed on the principal
         national securities exchange on which the shares of Common Stock are
         listed or admitted to trading or, if the shares of Common Stock are not
         listed or admitted to trading on any national securities exchange, the
         last quoted price or, if not so quoted, the average of the high bid and
         low asked prices in the over-the-counter market, as reported by the
         National Association of Securities Dealers, Inc. Automated Quotation
         System - National Market System ("NASDAQ") or such other system then in
         use, or, if on any such date the shares of Common Stock are not quoted
         by any such organization, the average of the closing bid and


                                       19
<PAGE>   23

         asked prices as furnished by a professional market maker making a
         market in the Common Stock selected by the Board. If on any such date
         no market maker is making a market in the Common Stock, the fair value
         of such shares on such date as determined in good faith by the Board
         shall be used. The term "Trading Day" shall mean a day on which the
         principal national securities exchange on which the shares of Common
         Stock are listed or admitted to trading is open for the transaction of
         business or, if the shares of Common Stock are not listed or admitted
         to trading on any national securities exchange, a Business Day. If the
         Common Stock is 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, whose determination shall be
         described in a statement filed with the Rights Agent and shall be
         conclusive for all purposes.

                           (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
         Common Stock in clause (i) of this Section 11(d) (other than the last
         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 number may be appropriately adjusted
         for such events as stock splits, stock dividends and recapitalizations
         with respect to the Common Stock occurring after the date of this
         Agreement) multiplied by the current market price per share of the
         Common Stock. If neither the Common Stock nor the 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, whose determination shall be
         described in a statement filed with the Rights Agent and shall be
         conclusive for all purposes. For all purposes of this Agreement, the
         "current market price" of one one-hundredth of a share 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 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 (3) years from the date of the
transaction which mandates such adjustment, or (ii) the Expiration Date.

                           (f)      If as a result of Section 11(a)(ii) or
Section 13(a) or any adjustment made pursuant to Section 11(a)(ii) or Section
13(a) hereof, the holder of any Right 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


                                       20
<PAGE>   24

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 one
one-hundredths of a share of Preferred Stock purchasable from time to time
hereunder upon exercise of the Rights, all subject to further adjustment as
provided herein.

                           (h)      Unless the Company shall have exercised its
election as provided in Section 11(i), upon each adjustment of the Purchase
Price as a result of the calculations made in Sections 11(b) and (c), each Right
outstanding immediately prior to the making of each adjustment shall thereafter
evidence the right to purchase, at the adjusted Purchase Price, that number of
one one-hundredths of a share of Preferred Stock (calculated to the nearest
one-millionth) obtained by (i) multiplying (x) the number of one one-hundredths
of a share covered by a Right immediately prior to this adjustment, by (y) the
Purchase Price in effect immediately prior to such adjustment of the Purchase
Price, and (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 one one-hundredths of a share of Preferred
Stock purchasable 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 one one-hundredths of a share of Preferred Stock for which a Right was
exercisable immediately prior to such adjustment. Each Right held of record
prior to such adjustment of the number of Rights shall become that number of
Rights (calculated to the nearest one-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, with prompt notice
thereof to the Rights Agent. 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 (10) days later than the
date of the 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 so to be
distributed shall be issued, executed and countersigned in the manner provided
for herein (and may bear, at the option


                                       21
<PAGE>   25

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 one one-hundredths of a share of Preferred
Stock issuable upon the exercise of the Rights, the Rights Certificates
theretofore and thereafter issued may continue to express the Purchase Price per
one one-hundredth of a share and the number of one one-hundredth of a share
which were 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 stated par value, if any,
of the number of one one-hundredths of a share 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 fully paid and nonassessable such number of one
one-hundredths of a share of Preferred Stock 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, with prompt
notice thereof to the Rights Agent, until the occurrence of such event the
issuance to the holder of any Right exercised after such record date the number
of one one-hundredths of a share of Preferred Stock and other capital stock or
securities of the Company, if any, issuable upon such exercise over and above
the number of one one-hundredths of a share of Preferred Stock and other capital
stock or securities of the Company, if any, issuable upon such exercise on the
basis of the Purchase Price in effect prior to such adjustment; provided,
however, that the Company shall deliver to such holder a due bill or other
appropriate instrument evidencing such holder's right to receive such additional
shares (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 its good faith judgment the Board 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 stockholders.

                           (n)      The Company covenants and agrees that it
shall not, at any time after the Distribution Date, (i) consolidate 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 related 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


                                       22
<PAGE>   26

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 consolidation, 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 consolidation, merger or sale, the stockholders of the Person who
constitutes, or would constitute, the "Principal Party" for purposes of Section
13(a) hereof shall have received a distribution of Rights previously owned by
such Person or any of its Affiliates and Associates.

                           (o)      The Company covenants and agrees that, after
the Distribution Date, it will 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 Common stock payable in 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, the
number of Rights associated with each share of 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 Common Stock following any such event shall equal the result
obtained by multiplying the number of Rights associated with each share of
Common Stock immediately prior to such event by a fraction the numerator of
which shall be the total number of shares of Common Stock outstanding
immediately prior to the occurrence of the event and the denominator of which
shall be the total number of shares of Common Stock outstanding immediately
following the occurrence of such event.

                           (q)      The failure by the Board to declare a
Person to be an Adverse Person following such Person becoming the Beneficial
Owner of 10% or more of the outstanding Common Stock shall not imply that such
Person is not an Adverse Person or limit the Board's right at any time in the
future to declare such Person to be an Adverse Person.

                  Section 12.       Certificate of Adjusted Purchase Price or
Number of Shares.

                  Whenever an adjustment is made as provided in Section 11 or
Section 13 hereof, the Company shall (a) promptly prepare a certificate setting
forth such adjustment and a brief statement of the facts and computations
accounting for such adjustment, (b) promptly file with the Rights Agent, and
with each transfer agent for the Preferred Stock and the 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 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 have no duty with
respect to, and shall not be deemed to have knowledge of, any such adjustment
unless and until it shall have received such certification.

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

                           (a)      In the event that, following the Stock
Acquisition Date, directly or indirectly, (x) the Company shall consolidate
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
consolidation or merger, (y) any Person (other than a Subsidiary of the Company
in a transaction which complies with Section 11(o) hereof) shall consolidate
with, or merge with or into, the Company, and the Company shall be the
continuing or surviving corporation of such consolidation or merger and, in
connection with such consolidation or merger, all or part of the outstanding
shares of Common Stock shall be changed 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), in one transaction or a series of related
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
Person or Person (other than the Company or any Subsidiary of the Company in
one or more transactions each of which complies with Section 11(o) hereof),
then, and in each such case (except as may be contemplated by Section 13(d)
hereof), 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 in
accordance with the terms of this Agreement, such number of validly authorized
and issued, fully paid, non-assessable and freely tradeable shares of Common
Stock of the Principal Party, free of all liens, encumbrances, rights of first
refusal or other adverse claims, as shall be equal to the result obtained by
(1) multiplying the then current Purchase Price by the number of one
one-hundredths of a share 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 one one-hundredths of a share for
which a Right was exercisable immediately prior to the first occurrence of a
Section 11(a)(ii) Event by the Purchase Price in effect immediately prior to
such first occurrence), and dividing that product (which, following the first
occurrence of a Section 13 Event, shall be referred to as the "Purchase Price"
for each Right and for all purposes of this Agreement) by (2) 50% of the
current market price 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 assure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation 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 effect
following the first occurrence of any Section 13 Event.

                           (b)      "Principal Party" shall mean


                                      24
<PAGE>   28

                                    (i)     in the case of any transaction
         described in clause (x) or (y) of the first sentence of Section 13(a),
         the Person that is the issuer of any securities into which shares of
         Common Stock of the Company are converted in such merger or
         consolidation, and if no securities are so issued, the Person that is
         the other party to such merger or consolidation; 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 greatest portion of the assets
         or earning power transferred pursuant to such transaction or
         transactions;

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 (12) month period registered under Section 12 of the Exchange Act, and
such Person is a direct or indirect Subsidiary of another Person the Common
Stock of which is and has been so registered, "Principal Party" shall refer to
such other Person; and (2) in case such Person is a Subsidiary, directly or
indirectly, or more than one Person, the Common Stocks of two or more of which
are and have been so registered, "Principal Party" shall refer to whichever of
such Persons is the issuer of the Common Stock having the greatest aggregate
market value.

                           (c)      The Company shall not consummate any such
consolidation, 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 this 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, as soon as practicable after
the date of any consolidation, merger or sale of assets mentioned in paragraph
(a) of this Section 13, the Principal Party will:

                                    (i)      prepare and file a registration
         statement under the Act, with respect to the Rights and the securities
         purchasable upon exercise of the Rights on an appropriate form, and
         will use its best efforts to cause such registration statement to (A)
         become effective as soon as practicable after such filing and (B)
         remain effective (with a prospectus at all times meeting the
         requirements of the Act) until the Expiration Date; 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;

                                    (iii)    use its best efforts to obtain any
         necessary regulatory approvals in respect of the Common Stock of the
         Principal Party subject to purchase upon exercise of outstanding
         Rights; and

                                    (iv)     use its best efforts, if the
         Common Stock of the Principal Party shall be listed or admitted to
         trading on the New York Stock Exchange or on another national
         securities exchange, to list or admit to trading (or continue the
         listing of) the Rights


                                      25
<PAGE>   29

         and the securities purchasable upon exercise of the Rights on the New
         York Stock Exchange or such securities exchange, or, if the Common
         Stock of the Principal Party shall not be listed or admitted to
         trading on the New York Stock Exchange or a national securities
         exchange, to cause the Rights and the securities receivable upon
         exercise of the Rights to be authorized for quotation on NASDAQ or on
         such other system then in use.

                           (d)      Notwithstanding anything in this Agreement
to the contrary, Section 13 shall not be applicable to a transaction described
in subparagraphs (x) and (y) of Section 13(a) if (i) such transaction in
consummated with a Person or Persons who acquired shares of Common Stock
pursuant to a tender offer or exchange offer for all outstanding shares of
Common Stock which complies with that portion of Section 11(a)(ii)(A) relating
to a determination by a majority of the members of the Board who are not
representatives, nominees, Affiliates or Associates of an Acquiring Person and
who are not officers of the Company that such tender offer or exchange offer is
fair to the stockholders and otherwise in the best interests of the Company and
its stockholders, all as set forth in Section 11(a)(ii)(A) hereof (or a wholly
owned subsidiary of any such Person or Persons), (ii) the price per share of
Common Stock offered in such transaction is not less than the price per share
of Common Stock paid to all holders of shares of Common Stock whose shares were
purchased pursuant to such tender offer or exchange offer and (iii) the form of
consideration being offered to the remaining holders of shares of Common Stock
pursuant to such transaction is the same as the form of consideration paid
pursuant to such tender offer or exchange offer. Upon consummation of any such
transaction contemplated by this Section 13(d), all Rights hereunder shall
expire.

                           (e)      The provisions of this Section 13 shall
similarly apply to successive mergers or consolidations or sales 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, except prior to the Distribution Date as provided in
Section 11(p) hereof, or to distribute Rights Certificates which evidence
fractional Rights. In lieu of such fractional Rights, there shall be paid to
the registered holders of the Rights Certificates with regard to which such
fractional Rights would otherwise be issuable, an amount in cash equal to the
same fraction of the current market value of a whole Right. For purposes of
this Section 14(a), the current market value of a whole Right shall be the
closing price of the Rights for the Trading Day immediately prior to the date
on which such fractional Rights would have been otherwise issuable. The closing
price of the Rights for any day shall be the last sale price, regular way, or,
in case no such sale takes place on such day, the average of the closing bid
and asked prices, regular way, in either case as reported in the principal
consolidated transaction reporting system with respect to securities listed or
admitted to trading on the New York Stock Exchange or, if the Rights are not
listed or admitted to trading on the New York Stock Exchange, as reported in
the principal consolidated transaction reporting system with respect to
securities listed on the principal national securities exchange on which the
Rights are listed or admitted to trading, or if the Rights are not listed or
admitted to trading on any national


                                      26
<PAGE>   30

securities exchange, the last quoted price or, if not so quoted, the average of
the high bid and low asked prices in the over-the-counter market, as reported
by NASDAQ or such other system then in use or, if on any such date the Rights
are not quoted by any such organization, the average of the closing bid and
asked prices as furnished by a professional market maker making a market in the
Rights selected by the Board. 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 shall be used.

                           (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 to distribute
certificates which evidence fractional shares of Preferred Stock (other than
fractions which are integral multiples of one one-hundredth of a share of
Preferred Stock). In lieu of fractional shares of Preferred Stock that are not
integral multiples of one one-hundredth of a share of Preferred Stock, 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 current market value of one one-hundredth of a share of
Preferred Stock. For purposes of this Section 14(b), the current market value
of one one-hundredth of a share of Preferred Stock shall be one one-hundredth
of the closing price of a share of Preferred Stock (as determined pursuant to
Section 11(d)(ii) hereof) for the Trading Day immediately prior to the date of
such exercise.

                           (c)      Following the occurrence of a Triggering
Event, the Company shall not be required to issue fractions of shares of Common
Stock upon exercise of the Rights or to distribute certificates which evidence
fractional shares of Common Stock. In lieu of fractional shares of Common
Stock, 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 current market value of one (1) share of Common
Stock. For purposes of this Section 14(c), the current market value of one
share of Common Stock shall be the closing price of one share of Common Stock
(as determined pursuant to Section 11(d)(i) hereof) for the Trading Day
immediately prior to the date of such exercise or exchange.

                           (d)      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 are vested in the respective registered holders of
the Rights Certificates (and, prior to the Distribution Date, the registered
holders of the Common Stock); and any registered holder of any Rights
Certificate (or, prior to the Distribution Date, of the 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 the 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 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


                                      27
<PAGE>   31

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
will be transferable only in connection with the transfer of 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 principal office or offices of the Rights Agent designated
for such purposes, duly endorsed or accompanied by a proper instrument of
transfer and with appropriate forms and certificates fully executed;

                           (c)      subject to the provisions of 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, the associated 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
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 required
to be affected by any notice to the contrary; and

                           (d)      notwithstanding anything in this Agreement
to the contrary, neither the Company nor the Rights Agent shall have any
liability to any holder of a Right or 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 obligations; provided,
however, the Company must use its best efforts to have any such order, decree
or ruling lifted or otherwise overturned as soon as possible.

                  Section 17.       Rights Certificate Holder Not Deemed a
Stockholder. 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 one one-hundredths of a share 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 stockholder of the Company or any right to vote
for the election of directors or upon any matter submitted to stockholder at
any meeting thereof, or to give or withhold consent to any corporate action, or
to receive notice of meetings or other actions affecting stockholders (except
as provided in Section 25 hereof), or to receive dividends or subscription
rights, or otherwise, until the Right or Rights


                                      28
<PAGE>   32

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 and
counsel fees and disbursements and other disbursements incurred in the
administration, preparation, delivery, amendment and execution of this
Agreement and the exercise and performance of its duties hereunder. The Company
also agrees to indemnify the Rights Agent for, and to hold it harmless against,
any loss, liability, damage, judgment, fine, penalty, claim, demand,
settlement, cost or expense, incurred without gross negligence, bad faith or
willful misconduct on the part of the Rights Agent, for any action taken,
suffered or omitted by the Rights Agent in connection with the acceptance and
administration of this Agreement, including, without limitation, the costs and
expenses of defending against any claim of liability in the premises. The
indemnity provided herein shall survive the termination of this Agreement and
the termination and expiration of the Rights. The reasonable costs and expenses
incurred in enforcing this right of indemnification shall be paid by the
Company. Anything to the contrary notwithstanding, in no event shall the Rights
Agent be liable for special, punitive, indirect, consequential or incidental
loss or damage of any kind whatsoever (including but not limited to lost
profits), even if the Rights Agent has been advised of the likelihood of such
loss or damage.

                           (b)      The Rights Agent shall be authorized and
protected and shall incur no liability for or in respect of any action taken,
suffered or omitted by it in connection with its administration of this
Agreement in reliance upon any Rights Certificate or certificate for 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 be signed, executed and, where necessary, verified or
acknowledged, by the proper Person or Persons, or otherwise upon the advice of
counsel as set forth in Section 20 hereof.

                  Section 19.       Merger or Consolidation or Change of Name of
Rights Agent.

                           (a)      Any Person into which the Rights Agent or
any successor Rights Agent may be merged or with which it may be consolidated,
or any corporation resulting from any merger or consolidation to which the
Rights Agent or any successor Rights Agent shall be a party, or any Person
succeeding to the shareholder services business of the Rights Agent or any
successor Rights Agent, shall be the successor to the Rights Agent under this
Agreement without the execution of filing of any paper or any further act on
the part of any of the parties hereto; provided, however, that such Person
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 a 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


                                      29
<PAGE>   33

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 only the duties and obligations expressly imposed by this Agreement
upon the following terms and conditions, by all of which the Company and the
holders of Rights Certificates, by their acceptance thereof, shall be bound:

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

                           (b)      Whenever in the performance of its duties
under this Agreement the Rights Agent shall deem it necessary or desirable that
any fact or matter (including, without limitation, the identity of any
Acquiring Person or Adverse Person and the determination of "current market
price") be proved or established by the Company prior to taking, suffering or
omitting any action hereunder, such fact or matter (unless other evidence in
respect thereof be herein specifically prescribed) may be deemed to be
conclusively proved and established by a certificate signed by the Chairman of
the Board, the President, any Vice President, the Treasurer, or the Secretary
of the Company and delivered to the Rights Agent; and such certificate shall be
full authorization and protection to the Rights Agent and the Rights Agent
shall incur no liability for or in respect of any action taken, suffered or
omitted in good faith by it under the provisions of this Agreement in reliance
upon such certificate.

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

                           (d)      The Rights Agent shall not be liable for or
by reason of any of the statements of fact or recitals contained in this
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.

                           (e)      The Rights Agent shall not be under any
liability or responsibility in respect of the validity of this Agreement or the
execution and delivery hereof (except the due execution hereof by the Rights
Agent) or in respect of the validity or execution of any Rights


                                      30
<PAGE>   34

Certificate (except its countersignature thereof); nor shall it be responsible
for any breach by the Company of any covenant or condition 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
responsible for the manner, method or amount of any such adjustment or the
ascertaining of the existence of facts that would require any such adjustment
(except with respect to the exercise of Rights evidenced by Rights Certificates
after actual notice of any such adjustment); 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 Common Stock or Preferred Stock to be issued
pursuant to this Agreement or any Rights Certificate or as to whether any
shares of Common Stock or Preferred Stock will, when so issued, be validly
authorized and issued, fully paid and nonassessable.

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

                           (g)      The Rights Agent is hereby authorized and
directed to accept instructions with respect to the performance of its duties
hereunder from any Person reasonably believed by the Rights Agent to be 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 for any action taken, suffered or omitted by
it in good faith in accordance with instructions of any such officer or for any
delay in acting while waiting for those instructions.

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

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

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


                                      31
<PAGE>   35

                           (k)      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 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.

                  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 (30) days' notice in writing mailed to the Company,
and to each transfer agent of the Common Stock and Preferred 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 (30) days' notice in writing, mailed to the Rights
Agent or successor Rights Agent, as the case may be, and to each transfer agent
of the Common Stock and Preferred 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 (30) days after giving
notice of such removal or after it has been notified in writing of such
resignation or incapacity by the resigning or incapacitated Rights Agent or by
the holder of a 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) an entity organized
and doing business under the laws of the United States or the laws of any state
of the United States, or District of Columbia, in good standing, which is
authorized under such laws to exercise the powers of the Rights Agent
contemplated by this Agreement and is subject to supervision or examination by
federal or state authority or (b) an Affiliate of a corporation described in
clause (a) of this sentence. After appointment, the successor Rights Agent
shall be vested with the same powers, rights, duties and responsibilities as if
it had been originally named as Rights Agent without further act or deed; but
the predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver
any further assurance, conveyance, act or deed necessary for the purpose. Not
later than the effective date of any such appointment, the Company shall file
notice thereof in writing with the predecessor Rights Agent and each transfer
agent of the Common Stock and Preferred 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, as the case may
be.

                  Section 22.       Issuance of New Rights Certificates.
Notwithstanding any of the provisions of this Agreement or of the Rights to the
contrary, the Company may, at its option, issue new Rights Certificates
evidencing Rights in such form as may be approved by its Board to reflect any
adjustment or change in the Purchase Price and the number or kind or class of
shares or other securities or property purchasable under the Rights
Certificates made in accordance with the provisions of this Agreement. In
addition, in connection with the issuance or sale of shares of Common Stock
following the Distribution Date and prior to the redemption or expiration of
the Rights, the Company (a) shall, with respect to shares of Common Stock so
issued or sold pursuant


                                      32
<PAGE>   36

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, 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 its counsel that such issuance would create a significant
risk of material adverse tax 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)      The Board of Directors may, at its option,
at any time prior to the earlier of (i) the Close of Business on the tenth
(10th) day following the Stock Acquisition Date (or, if the Stock Acquisition
Date shall have occurred prior to the Record Date, the Close of Business on the
tenth (10th) day following the Record Date), or (ii) the Final Expiration Date,
redeem all but not less than all the then outstanding Rights at a redemption
price of $0.01 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 hereinafter referred to as the
"Redemption Price"). Notwithstanding the foregoing, the Board may not redeem
any Rights following its determination that any Person is an Adverse Person.
If, following the occurrence of a Stock Acquisition Date and following the
expiration of the right of redemption hereunder but prior to any Triggering
Event, (i) a Person who is an Acquiring Person shall have transferred or
otherwise disposed of a number of shares of Common Stock in one transaction or
series of transactions, not directly or indirectly involving the Company or any
of its Subsidiaries, which did not result in the occurrence of a Triggering
Event such that such Person is thereafter a Beneficial Owner of 10% or less of
the outstanding shares of Common Stock, (ii) there are no other Persons,
immediately following the occurrence of the event described in clause (i), who
are Acquiring Persons, and (iii) the Board shall so approve, then the right of
redemption shall be reinstated and thereafter be subject to the provisions of
this Section 23(a). Notwithstanding anything contained 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. The Company may, at its option, pay the Redemption Price
in cash, shares of Common Stock (based on the Current Market Price of the
Common Stock at the time of redemption) or any other form of consideration
deemed appropriate by the Board of Directors.

                           (b)      Immediately upon the action of the Board of
Directors ordering the redemption of the Rights, evidence of which shall have
been 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 the Common
Stock; provided, however, that the failure to


                                      33
<PAGE>   37

give, or any defect in, such notice shall not affect the validity of such
redemption. 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.

         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 or any Person
is determined to an Adverse Person under Section 11(a)(ii)(B), exchange all or
part of the then outstanding and exercisable Rights (which shall not include
Rights that have become null and void pursuant to the provisions of Section
7(e) hereof) for Common Shares at an exchange ratio of one Common Share 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 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 of any such
Subsidiary, or any entity holding Common Shares for or pursuant to the terms of
any such plan), together with all Affiliates and Associates of such Person,
becomes the Beneficial Owner of 50% or more of the Common Shares then
outstanding.

                  (b)      Immediately upon the action of the Board of
Directors of the Company ordering the exchange of any Rights pursuant to
paragraph (a) of this Section 24 and without any further action and without any
notice, the right to exercise such Rights shall terminate and the only right
thereafter of holders of such Rights shall be to receive that number of Common
Shares equal to the number of such Rights held by such holder multiplied by the
Exchange Ratio. The Company shall promptly give public notice of any such
exchange with prompt notice thereof to the Rights Agent; provided, however,
that the failure to give, or any defect in, such notice shall not affect the
validity of such exchange. The Company promptly shall mail a notice of any such
exchange to all of the holders of such Rights at their last addresses as they
appear upon the registry books of the Rights Agent. Any notice which is mailed
in the manner herein provided shall be deemed given, whether or not the holder
receives the notice. Each such notice of exchange will state the method by
which the exchange of the Common Shares for Rights will be effected and, in the
event of any partial exchange, the number of Rights which will be exchanged.
Any partial exchange shall be effected pro rata based on the number of Rights
(other than Rights which have become null and void pursuant to the provisions
of Section 7(e)) held by each holder of Rights.

                  (c)      In any exchange pursuant to this Section 24, the
Company, at its option, may substitute Preferred Shares (or equivalent
preferred shares) for Common Shares exchangeable for Rights, at the initial
rate of one one-hundredth of a Preferred Share (or equivalent preferred share)
for each Common Share, as appropriately adjusted to reflect the adjustments in
the voting rights of the Preferred Shares pursuant to the terms thereof, so
that the fraction of a Preferred Share delivered in lieu of each Common Share
shall have the same voting rights as one Common Share. The Company may also, at
its option, substitute for each Common Share that would otherwise be issuable
upon exchange of a Right a number of Preferred Shares (or equivalent preferred
shares) or fraction thereof such that the current per share market price of one
Preferred Share multiplied by


                                      34
<PAGE>   38

such number of fraction is equal to the current per share market price of one
Common Share as of the date of issuance of such Preferred Shares or fraction
thereof.

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

                  Section 25.       Notice of Certain Events.

                           (a)      In case the Company 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), or (ii) to offer to the
holders of the 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, or (iii) to effect any
reclassification of its Preferred Stock (other than a reclassification
involving only the subdivision of outstanding shares of Preferred Stock ), or
(iv) to effect any consolidation 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
transaction or a series of related 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 and the Rights Agent, 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, consolidation, 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.

                           (b)      In case any of the events set forth in
Section 11(a)(ii) hereof shall occur, then, in any such case, (i) 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 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,
and (ii) all references in the preceding


                                      35
<PAGE>   39

paragraph to Preferred Stock shall be deemed thereafter to refer to Common
Stock and/or, if appropriate, other securities.

                  Section 26.       Notices. Notices or demands authorized by
this Agreement to be given or made by the Rights Agent or by the holder of any
Rights Certificate to or on the Company shall be sufficiently given or made if
sent by first-class mail, postage prepaid, addressed (until another address is
filed in writing with the Rights Agent) as follows:

Subject to the provisions of Section 21, any notice or demand authorized by
this Agreement to be given or made by the Company or by the holder of any
Rights Certificate to or on the Rights Agent shall be sufficiently given or

                           Attention: Relationship Manager

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 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 Company.

                  Section 27.       Supplements and Amendments. Prior to the
Distribution Date and subject to the other provisions 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 Common Stock or holders of Rights. From and
after the Distribution Date and subject to the other provisions 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
not adversely affect the interest of the holders of Rights Certificates (other
than an Acquiring Person, an Adverse Person, or an Affiliate or Associate of an
Acquiring Person or Adverse Person); provided, however, this Agreement may not
be supplemented or amended to lengthen, pursuant to clause (iii) of this
sentence, (A) a time period relating to when the Rights may


                                      36
<PAGE>   40

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. Upon the delivery of a certificate from an appropriate officer of the
Company which states that the proposed supplement or amendment is in compliance
with the terms of this Section 27, and such supplement or amendment does not
change or increase the Rights Agent's duties, liabilities or obligations, 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 Final
Expiration Date, the Purchase Price or the number of one one-hundredths of a
share of Preferred Stock for which a Right is exercisable. Furthermore, the
Company may not amend this Agreement following the determination that any
Person is an Adverse Person. Prior to the Distribution Date, the interests of
the holders of Rights shall be deemed coincident with the interests of the
holders of 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. Except as otherwise provided herein, for all purposes of this
Agreement, any calculation of the number of shares of Common Stock outstanding
at any particular time, including for purposes of determining the particular
percentage of such outstanding shares of 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 General Rules and Regulations under the Exchange
Act. The Board shall have the exclusive power and authority to administer this
Agreement and to exercise all rights and powers specifically granted to the
Board or to the Company, or as may be necessary or advisable in the
administration of this Agreement, including, without limitation, the right and
power to (i) interpret the provisions of this Agreement and (ii) make all
determinations deemed necessary or advisable for the administration of this
Agreement (including a determination to redeem or not redeem the Rights, to
declare that a Person is an Adverse Person or to amend the 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 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 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 the 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 of the Rights Certificates (and, prior to the Distribution
Date, registered holders of the 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


                                      37
<PAGE>   41

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 determines in its good faith
judgment that severing the invalid language from this Agreement would adversely
affect the purpose or effect of this Agreement, 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 (10th) day following the date of such
determination by the Board.

                  Section 32.       Governing Law. This Agreement, each Right
and each Rights Certificate issued hereunder shall be deemed to be a contract
made under the laws of the State of Delaware, without regard to its principles
of conflicts of laws, and for all purposes shall be governed by and construed
in accordance with the laws of the State of Delaware applicable to contracts
made and to be performed entirely within the State of Delaware.

                  Section 33.       Counterparts. This Agreement may be executed
in any number of counterparts and each of such counterparts shall for all
purposes be deemed to be an original, and all such counterparts shall together
constitute but one and the same instrument.

                  Section 34.       Descriptive Headings. Descriptive headings
of several Sections of this Agreement are inserted for convenience only and
shall not control or affect the meaning or construction of any of the
provisions hereof.

                   CERTIFICATE OF DESIGNATION, PREFERENCES AND
           RIGHTS OF SERIES 1999 JUNIOR PARTICIPATING PREFERRED STOCK

                                       of

                             SOUTHTRUST CORPORATION

             Pursuant to Section 151 of the General Corporation Law
                            of the State of Delaware


                  We, Wallace D. Malone, Jr., the Chairman of the Board of
Directors of SouthTrust Corporation, a Delaware corporation (the "Corporation"),
and Alton E. Yother, the Secretary of the Corporation, in accordance with the
provisions of Section 103 of the General Corporation Law of the State of
Delaware, DO HEREBY CERTIFY:

                  That pursuant to the authority conferred upon the Board of
Directors by the Restated Certificate of Incorporation of the Corporation, the
Board of Directors on December 16, 1998 adopted the following resolutions
creating a series of 2,000,000 shares of Preferred Stock designated as Series
1999 Junior Participating Preferred Stock:

                  RESOLVED, that subject to the filing of this resolution with
the appropriate officials in accordance with Delaware law, and in accordance
with the authority granted by Article IV of the Restated Certificate of
Incorporation of the Corporation, as amended, a series of Preferred Stock, par
value $1.00 per share, consisting of 2,000,000 shares, is hereby established and
authorized to be issued, such Preferred Stock to have the following designation,
powers, preferences and relative, participating, optional and other special
rights, the qualifications, limitations and restrictions:

                  Section 1.        Designation and Amount. The shares of such
series shall be designated as the "Series 1999 Junior Participating Preferred
Stock" and the number of shares constituting such series shall be 2,000,000.

                  Section 2.        Dividends and Distributions.

                  (a)      Subject to the prior and superior rights of the
holders of any shares of any series of Preferred Stock ranking prior and
superior to the shares of Series 1999 Junior Participating Preferred Stock with
respect to dividends, the holders of shares of Series 1999 Junior Participating
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, quarterly
dividends payable in cash on the 30th day of March, June, September and December
in each year (each such date being referred to herein as a "Quarterly Dividend
Payment Date"), commencing on the first Quarterly Dividend Payment Date after
the first issuance of a share or fraction of a share of Series 1999 Junior
Participating Preferred Stock, in an amount per share (rounded to the nearest
cent) equal to the greater of (a) $10.00 or (b)


                                      A-1
<PAGE>   44

subject to the provision for adjustment hereinafter set forth, 100 times the
aggregate per share amount of all cash dividends, and 100 times the aggregate
per share amount (payable in kind) of all non-cash dividends or other
distributions other than a dividend payable in shares of Common Stock or a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise), declared on the Common Stock, par value $2.50 per share, of the
Corporation (the "Common Stock") since the immediately preceding Quarterly
Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment
Date, since the first issuance of any share or fraction of a share of Series
1999 Junior Participating Preferred Stock. In the event the Corporation shall at
any time after the Close of Business on February 22, 1999 (the "Rights
Declaration Date") (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then, in each such
case, the amount to which holders of shares of Series 1999 Junior Participating
Preferred Stock were entitled immediately prior to such event under clause (b)
of the preceding sentence shall be adjusted by multiplying such amount by a
fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

                  (b)      The Corporation shall declare a dividend or
distribution on the Series 1999 Junior Participating Preferred Stock as provided
in paragraph (a) above immediately after it declares a dividend or distribution
on the Common Stock (other than a dividend payable in shares of Common Stock);
provided that, in the event no dividend or distribution shall have been declared
on the Common Stock during the period between any Quarterly Dividend Payment
date and the next subsequent Quarterly Dividend Payment Date, a dividend of
$10.00 per share on the Series 1999 Junior Participating Preferred Stock shall
nevertheless be payable on such subsequent Quarterly Dividend Payment Date.

                  (c)      Dividends shall begin to accrue and be cumulative on
outstanding shares of Series 1999 Junior Participating Preferred Stock from the
Quarterly Dividend Payment Date next preceding the date of issue of such shares
of Series 1999 Junior Participating Preferred Stock, unless the date of issue of
such shares is prior to the record date for the first Quarterly Dividend Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a date after the record date for the determination of holders
of shares of Series 1999 Junior Participating Preferred Stock entitled to
receive a quarterly dividend and before such Quarterly Dividend Payment Date, in
either of which events such dividends shall begin to accrue and be cumulative
from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall
not bear interest. Dividends paid on the shares of Series 1999 Junior
Participating Preferred Stock in an amount less than the total amount of such
dividends at the time accrued and payable on such shares shall be allocated pro
rata on a share by share basis among all such shares at the time outstanding.
The Board of Directors may fix a record date for the determination of holders of
shares of Series 1999 Junior Participating Preferred Stock entitled to receive
payment of a dividend or distribution declared thereon, which record date shall
be no more than 60 days prior to the date fixed for the payment thereof.

                  Section 3.        Voting Rights.  The holders of shares of
Series 1999 Junior Participating Preferred Stock shall have the following voting
rights:

                  (a)      Subject to the provision for adjustment hereinafter
set forth, each share of Series 1999 Junior Participating Preferred Stock shall
entitle the holder thereof to 100 votes on all matters submitted to a vote of
the stockholders of the Corporation. In the event the Corporation shall at any
time after the Rights Declaration Date (i) declare any dividend on Common Stock
payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock,
or (iii) combine the outstanding Common Stock into a smaller number of shares,
then, in each such case, the number of votes per share to which holders of
shares of Series 1999 Junior Participating Preferred Stock were entitled
immediately prior to such event shall be adjusted by multiplying such number by
a fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

                  (b)      Except as otherwise provided herein or by law, the
holders of shares of Series 1999 Junior Participating Preferred Stock and the
holders of shares of Common Stock shall vote together as one class on all
matters submitted to a vote of stockholders of the Corporation.

                  (c)      (i)      If at any time dividends on any Series 1999
Junior Participating Preferred Stock shall be in arrears in an amount equal to
six (6) quarterly dividends thereon, the occurrence of such contingency shall
mark the beginning of a period (herein called a "default period") which shall
extend until such time when all accrued and unpaid dividends for all previous
quarterly dividend periods and for the current quarterly dividend on all shares
of Series 1999 Junior Participating Preferred Stock then outstanding shall have
been declared and paid or set apart for payment. During each default period, all
holders of Preferred Stock (including holders of the Series 1999 Junior
Participating Preferred Stock) with dividends in arrears in an amount equal to
six (6) quarterly dividends thereon, voting as a class, irrespective of series,
shall, in addition to all other voting rights which the holders of shares of the
Series 1999 Junior Participating Preferred Stock may have, have the right to
elect two (2) Directors.

                           (ii)     During any default period, such voting
rights of the holders of Series 1999 Junior Participating Preferred Stock may be
exercised initially at a special meeting called pursuant to subparagraph (iii)
of this Section 3(c) or at any annual meeting of stockholders, and thereafter at
annual meetings of stockholders, provided that neither such voting rights nor
the right of the holders of any other series of Preferred Stock, if any, to
increase, in certain cases, the authorized number of Directors shall be
exercised unless the holders of not less than ten percent (10%) in number of
shares of Preferred Stock outstanding shall be present in person or by proxy at
such meeting. The absence of a quorum of the holders of Common Stock shall not
affect the exercise by the holders of Preferred Stock of such voting rights. At
any meeting at which the holders of Preferred Stock shall exercise such voting
rights initially during an existing default period, they shall have the right,
voting as a class, to elect Directors to fill such vacancies, if any, in the
Board of Directors as may then exist up to two (2) Directors or, if such right
is exercised at an annual meeting, to elect two (2) Directors. If the number
which may be so elected at any special meeting does not amount to the required
number, the holders of the Preferred Stock shall have the


                                      A-3
<PAGE>   46

right to make such increase in the Directors as shall be necessary to permit the
election by them of the required number. After the holders of the Preferred
Stock shall have exercised their right to elect Directors in any default period
and during the continuance of such period, the number of Directors shall not be
increased or decreased except by vote of the holders of Preferred Stock as
herein provided or pursuant to the rights of any equity securities ranking
senior to or pari passu with the Series 1999 Junior Participating Stock.

                           (iii)    Unless the holders of Preferred Stock shall,
during an existing default period, have previously exercised their right to
elect Directors, the Board of Directors may order, or any stockholder or
stockholders owning in the aggregate not less than ten percent (10%) of the
total number of shares of Preferred Stock outstanding, irrespective of series,
may request, the calling of a special meeting of the holders of Preferred Stock,
which meeting shall thereupon be called by the Chairman of the Board of
Directors, the President, a Vice-President or the Secretary of the Corporation.
Notice of such meeting and of any annual meeting at which holders of Preferred
Stock are entitled to vote pursuant to this paragraph (c)(iii) shall be given to
each holder of record of Preferred Stock by mailing a copy of such notice to him
at his last address as the same appears on the books of the Corporation. Such
meeting shall be called for a time not earlier than 20 days and not later than
60 days after such order or request; or in default of the calling of such
meeting within 60 days after such order or request, such meeting may be called
on similar notice by any stockholder or stockholders owning in the aggregate not
less than ten percent (10%) of the total number of shares of Preferred Stock
outstanding. Notwithstanding the provisions of this paragraph (c)(iii), no such
special meeting shall be called during the period within 60 days immediately
preceding the date fixed for the next annual meeting of the stockholders.

                           (iv)     In any default period, the holders of Common
Stock, and other classes of stock of the Corporation if applicable, shall
continue to be entitled to elect the whole number of Directors until the holders
of Preferred Stock shall have exercised their right to elect two (2) Directors
voting as a class, after the exercise of which right (x) the Directors so
elected by the holders of Preferred Stock shall continue in office until their
successors shall have been elected by such holders or until the expiration of
the default period, and (y) any vacancy in the Board of Directors may (except as
provided in paragraph (c)(ii) of this Section 3) be filled by vote of a majority
of the remaining Directors theretofore elected by the holders of the class of
stock which elected the Director whose office shall become vacant. References in
this paragraph (c) to Directors elected by the holders of a particular class of
stock shall include Directors elected by such Directors to fill vacancies as
provided in clause (y) of the foregoing sentence.

                           (v)      Immediately upon the expiration of a default
period, (x) the right of the holders of Preferred Stock as a class to elect
Directors shall cease, (y) the term of any Directors elected by the holders of
Preferred Stock as a class shall terminate, and (z) the number of Directors
shall be such number as may be provided for in the Restated Certificate of
Incorporation or Bylaws irrespective of any increase made pursuant to the
provisions of paragraph (c)(ii) of this Section 3 (such number being subject,
however, to change thereafter in any manner provided by law or in the Restated
Certificate of Incorporation or Bylaws). Any vacancies in the Board of Directors
effected by the provisions of clauses (y) and (z) in the preceding sentence may
be filled by a majority of the remaining Directors.

<PAGE>   47

                  (d)      Except as set forth herein, holders of Series 1999
Junior Participating 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 Common Stock as set forth herein) for taking any corporate
action.

                  Section 4.        Certain Restrictions.

                  (a)      Whenever quarterly dividends or other dividends or
distributions payable on the Series 1999 Junior Participating Preferred Stock as
provided in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of Series
1999 Junior Participating Preferred Stock outstanding shall have been paid in
full, the Corporation shall not

                           (i)      declare or pay dividends on, make any other
distributions on, or redeem or purchase or otherwise acquire for consideration
any shares of stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up of the Corporation) to the Series 1999 Junior
Participating Preferred Stock;

                           (ii)     declare or pay dividends on or make any
other distributions on any shares of stock ranking on a parity (either as to
dividends or upon liquidation, dissolution or winding up of the Corporation)
with the Series 1999 Junior Participating Preferred Stock, except dividends paid
ratably on the Series 1999 Junior Participating Preferred Stock and all such
parity stock on which dividends are payable or in arrears in proportion to the
total amounts to which the holders of all such shares are then entitled;

                           (iii)    redeem or purchase or otherwise acquire for
consideration shares of any stock ranking on a parity (either as to dividends or
upon liquidation, dissolution or winding up of the Corporation) with the Series
1999 Junior Participating Preferred Stock, provided that the Corporation may at
any time redeem, purchase or otherwise acquire shares of any such parity stock
in exchange for shares of any stock of the Corporation ranking junior (either as
to dividends or upon dissolution, liquidation or winding up) to the Series 1999
Junior Participating Preferred Stock; or

                           (iv)     purchase or otherwise acquire for
consideration any shares of Series 1999 Junior Participating Preferred Stock, or
any shares of stock ranking on a parity with the Series 1999 Junior
Participating Preferred Stock, except in accordance with a purchase offer made
in writing or by publication (as determined by the Board of Directors) to all
holders of such shares upon such terms as the Board of Directors, after
consideration of the respective annual dividend rates and other relative rights
and preferences of the respective series and classes, shall determine in good
faith will result in fair and equitable treatment among the respective series or
classes.

                  (b)      The Corporation shall not permit any subsidiary of
the Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the


                                      A-5
<PAGE>   48

Corporation could, under paragraph (a) of this Section 4, purchase or otherwise
acquire such shares at such time and in such manner.

                  Section 5.        Reacquired Shares. Any shares of Series 1999
Junior Participating Preferred Stock purchased or otherwise acquired by the
Corporation in any manner whatsoever shall be retired and canceled promptly
after the acquisition thereof. All such shares shall upon their cancellation
become authorized but unissued shares of Preferred Stock and may be reissued as
part of a new series of 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 or in the Restated Certificate of
Incorporation of the Corporation.

                  Section 6.        Liquidation, Dissolution or Winding Up. Upon
any voluntary or involuntary liquidation, dissolution or winding-up of the
Corporation, no distribution shall be made (i) to the holders of shares of
Common Stock or any other stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding-up) to the Series 1999 Junior Participating
Preferred Stock unless prior thereto, the holders of shares of Series 1999
Junior Participating Preferred Stock shall have received the higher of $100.00
per share, plus an amount equal to accrued and unpaid dividends and
distributions thereon, whether or not declared, to the date of such payment, or
an aggregate amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 100 times the aggregate amount to be distributed
per share to the holders of Common Stock; nor (ii) to the holders of stock
ranking on a parity (either as to dividends or upon liquidation, dissolution or
winding-up) with the Series 1999 Junior Participating Preferred Stock, except
distributions made ratably on the Series 1999 Junior Participating Preferred
Stock and all other such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding-up. In the event the Corporation shall at any time
declare or pay any dividend on Common Stock payable in shares of Common Stock,
or effect a subdivision or combination or consolidation of the outstanding
shares of Common Stock (by reclassification or otherwise than by payment of a
dividend in shares of Common Stock) into a greater or lesser number of shares of
Common Stock, then, in each such case, the aggregate amount to which holders of
shares of Series 1999 Junior Participating Preferred Stock were entitled
immediately prior to such event under the provision in clause (i) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

                  Section 7.        Consolidation, Merger, etc. In case the
Corporation shall enter into any consolidation, merger, combination or other
transaction in which the shares of Common Stock are exchanged for or changed
into other stock or securities, cash and/or any other property, then in any such
case the shares of Series 1999 Junior Participating Preferred Stock shall at the
same time be similarly exchanged or changed in an amount per share (subject to
the provision for adjustment hereinafter set forth) equal to 100 times 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 changed or exchanged. In the event the Corporation shall at any time after
the Rights Declaration Date (i) declare any dividend on Common Stock payable in
shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
combine the outstanding Common Stock into


                                      A-6
<PAGE>   49

a smaller number of shares, then, in each such case, the amount set forth in the
preceding sentence with respect to the exchange or change of shares of Series
1999 Junior Participating Preferred Stock shall be adjusted by multiplying such
amount by a fraction the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

                  Section 8.        No Redemption. The shares of Series 1999
Junior Participating Preferred Stock shall not be redeemable.

                  Section 9.        Ranking. The Series 1999 Junior
Participating Preferred Stock shall rank junior to all other series of the
Corporation's Preferred Stock as to the payment of dividends and the
distribution of assets, unless the terms of any such series shall provide
otherwise.

                  Section 10.       Amendment. The Restated Certificate of
Incorporation of the Corporation shall not be amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Series 1999 Junior Participating Preferred Stock so as to affect them adversely
without the affirmative vote of the holders of a majority or more of the

                  This certifies that _________________________________, or
registered assigns, is the registered owner of the number of Rights set forth
above, each of which entitles the owner thereof, subject to the terms,
provisions and conditions of the Rights Agreement dated as of ________________,
199__ (the "Rights Agreement"), between SouthTrust Corporation, a Delaware
corporation (the "Company"), and _____________ , a _____________ (the "Rights
Agent"), to purchase from the Company at any time prior to 5:00 p.m.
(Birmingham, Alabama time) on February 22, 2009 at the office or offices of the
Rights Agent designated for such purpose, or its successors as Rights Agent, one
one-hundredth of a fully paid, non-assessable share of Series 1999 Junior
Participating Preferred Stock (the "Preferred Stock") of the Company, at a
purchase price of $150.00 per one one-hundredth of a share (the "Purchase
Price"), upon presentation and surrender of this Rights Certificate with the
Form of Election to Purchase and related Certificate duly executed. The number
of rights evidenced by this Rights Certificate (and the number of shares which
may be purchased upon exercise thereof) set forth above, and the Purchase Price
set forth above, are the number and Purchase Price as of the Close of Business
(as defined in the Rights Agreement) on February 22, 1999, based on the
Preferred Stock as constituted at such date.

                  Upon the occurrence of a Section 11(a)(ii) Event (as such term
is defined in the Rights Agreement), if the Rights evidenced by this Rights
Certificate are beneficially owned by (i) an Acquiring Person, an Adverse Person
or an Associate or Affiliate of any such Person (as such terms are defined in
the Rights Agreement), which the Company's Board of Directors, in its sole
discretion, determines is or was involved in or caused or facilitated, directly
or indirectly (including through any change in the Board), such Section
11(a)(ii) Event, (ii) a transferee of any such Acquiring Person, Adverse Person,
Associate or Affiliate who becomes a transferee after such Acquiring Person,
Adverse Person, Associate or Affiliate becomes such, or (iii) under certain
circumstances specified in the Rights Agreement, a transferee of any such
Acquiring Person, Adverse Person, Associate or Affiliate who becomes a
transferee prior to or concurrently with such Acquiring Person or Adverse Person
becoming such, 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 11(a)(ii) Event.

         As provided in the Rights Agreement, the Purchase Price and the number
and kind of shares of Preferred Stock or other securities, which may be
purchased upon the exercise of the Rights evidenced by this Rights Certificate
are subject to modification and adjustment upon the happening of certain events,
all as specified in the Rights Agreement.

         This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities hereunder of the
Rights Agent, the Company and the holders or the Rights Certificates, which
limitations of rights include the temporary suspension of the exercisability of
such Rights under the specific circumstances set forth in the Rights Agreement.
Copies of the Rights Agreement are on file at the above-mentioned office of the
Rights Agent and are also available upon written request to the Rights Agent.


                                      B-2
<PAGE>   52

         This Rights Certificate, with or without other Rights Certificates,
upon surrender at the principal office or offices of the Rights Agent designated
for such purpose, may be exchanged for another Rights Certificate or Rights
Certificates of like tenor and date evidencing Rights entitling the holder to
purchase a like aggregate number of one one-hundredths of a share of Preferred
Stock as the Rights evidenced by the Rights Certificate or Rights Certificates
surrendered shall have entitled such holder to purchase. If this Rights
Certificate shall be exercised in part, the holder shall be entitled to receive
upon surrender hereof another Rights Certificate or Rights Certificates for the
number of whole Rights not exercised.

         Subject to the provisions of the Rights Agreement, the Rights evidenced
by this Certificate may (unless the Board of Directors shall have made a
determination that a Person is an Adverse Person) be redeemed by the Company at
its option at a redemption price of $0.01 per Right at any time prior to the
earlier of the close of business on (i) the twentieth day following the Stock
Acquisition Date (as such time period may be extended pursuant to the Rights
Agreement), and (ii) the Final Expiration Date (as defined in the Rights
Agreement). After the expiration of the redemption period, the Company's right
of redemption may be reinstated if an Acquiring Person reduces his beneficial
ownership to 10% or less of the outstanding shares of Common Stock in a
transaction or series of transactions not involving the Company, and such
reinstatement is approved by the Company's Board of Directors.

                  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 (excluding Rights held by an
Acquiring Person or Adverse Person that have become null and void) for shares of
Common Stock at an exchange ratio of one share of Common Stock per Right,
appropriately adjusted to reflect any stock split, stock dividend, or similar
transaction. Notwithstanding the foregoing, the Board of Directors cannot effect
such exchange at any time after any person, together with all affiliates and
associates of such person, becomes the beneficial owner of 50% or more of the
shares of Common Stock then outstanding. Immediately upon the action of the
Board of Directors of the Company ordering the exchange of any Rights and
without any further action and without any notice, the right to exercise such
Rights will terminate and the only right thereafter of a holder of such Rights
will be to receive that number of shares of Common Stock equal to the number of
such Rights held by such holder multiplied by the exchange ratio described
above. The Company will not issue fractions of shares of Common Stock or
distribute certificates which evidence fractional shares of Common Stock. In
lieu of such fractional shares of Common Stock, the Company will pay to the
registered holders of the Right certificates with regard to which such
fractional shares of Common Stock would otherwise be issuable an amount in cash
equal to the same fraction of the current market value of a whole share of
Common Stock.

                  No fractional share of Preferred Stock will be issued upon the
exercise of any Right or Rights evidenced hereby (other than fractions which are
integral multiples of one one-hundredth of a share of preferred Stock, which
may, at the election of the Company, be evidenced by depository receipts), but
in lieu thereof a cash payment will be made, as provided in the Rights
Agreement.

         No fractional shares of Preferred Stock will be issued upon the
exercise of any Right or Rights evidenced hereby (other than fractions which are
integral multiples of one one-hundredth of a share of preferred Stock, which
may, at the election of the Company, be evidenced by depository receipts), but
in lieu thereof a cash payment will be made, as provided in the Rights
Agreement.

                  No holder of this Rights Certificate shall be entitled to vote
or receive dividends or be deemed for any purpose the holder of shares of
Preferred Stock or of any other securities of the Company which may at any time
be issuable on the exercise hereof, nor shall anything contained in the Rights
Agreement or herein be construed to confer upon the holder hereof, as such, any
of the rights of a stockholder of the Company or any right to vote for the
election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or, to
receive notice of meetings or other actions affecting stockholders (except as
provided in the Rights Agreement), or to receive dividends or subscription
rights, or otherwise, until the Right or Rights evidenced by this Rights
Certificate shall have been exercised as provided in the Rights Agreement.

                  This Rights Certificate shall not be valid or obligatory for
any purpose until it shall have been countersigned by the Rights Agent.

                                                                       EXHIBIT C

                          SUMMARY OF RIGHTS TO PURCHASE
                                 PREFERRED STOCK


         On December 16, 1998, the Board of Directors of SouthTrust Corporation
(the "Company") declared a dividend distribution of one Right for each
outstanding share of Common Stock of the Company to stockholders of record at
the close of business on February 22, 1999. Each Right will, when exercisable,
entitle the registered holder to purchase from the Company a unit consisting of
one one-hundredth of a share (a "Unit") of Series 1999 Junior Participating
Preferred Stock, par value $1.00 per share (the "Preferred Stock"), at a
purchase price of $150.00 per Unit, subject to adjustment (the "Purchase
Price"). The terms of the Preferred Stock are such that one Unit is essentially
equivalent to one share of Common Stock. Preferred Stock, rather than Common
Stock, is used to implement the plan in order to avoid having to reserve a large
amount of Common Stock for the Rights. Upon certain events described below, the
Rights entitle the holder to receive Common Stock of the Company or securities
of an acquiring company. The description and terms of the Rights are set forth
in an Amended and Restated Rights Agreement (the "Rights Agreement") between the
Company and American Stock Transfer & Trust Company, as Rights Agent.

         Until the Distribution Date (defined below):

         (i)      the Rights will be evidenced by the Common Stock certificates
                  and will be transferred with and only with the Common Stock
                  certificates and no separate Rights Certificates will be
                  distributed,

         (ii)     new Common Stock certificates issued after close of business
                  on February 22, 1999 will contain a notation incorporating the
                  Rights Agreement by reference, and

         (iii)    the surrender for transfer of any certificates for Common
                  Stock outstanding will also constitute the transfer of the
                  Rights associated with the Common Stock represented by such
                  certificate.

The Rights will not be exercisable until the Distribution Date and will expire
at the close of business on February 22, 2009, unless earlier redeemed by the
Company as described below (the "Expiration Date").

         Unless previously redeemed, the Rights will separate from the Common
Stock and a Distribution Date will occur upon the earlier to occur of:

         (i)      The tenth day after a public announcement that a person (an
                  "Acquiring Person") or any associate or affiliate of an
                  Acquiring Person has acquired, or obtained the right to
                  acquire, beneficial ownership of 15% or more of the
                  outstanding shares of Common Stock,


                                      C-1
<PAGE>   60

         (ii)     The tenth business day after the commencement of, or public
                  announcement of an intention to commence, a tender offer or
                  exchange offer that would result in a person or group
                  beneficially owning 15% or more of the outstanding shares of
                  Common Stock, or

         (iii)    The tenth day after the Board of Directors of the Company
                  declares any person to be an Adverse Person, upon a
                  determination by the Board of Directors that such person,
                  alone or together with its affiliates and associates, has
                  become the beneficial owner of an amount of Common Stock which
                  is substantial (which amount shall in no event be less than
                  10% of the shares of Common Stock then outstanding) and that
                  (a) such person's ownership is intended to cause the Company
                  to repurchase the Common Stock owned by such person or to take
                  other action to provide such person with short-term financial
                  gain where the best long-term interests of the Company and its
                  stockholders would not be served by taking such action at that
                  time or (b) such person's ownership may cause a material
                  adverse impact (including by jeopardizing the Company's
                  authorizations from, or relationships with, federal or state
                  regulators, or impairment of the Company's relationships with
                  customers or its ability to maintain its financial or
                  competitive position) on the business or prospects of the
                  Company to the detriment of the Company's stockholders.

         As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to holders of record of the Common Stock as of the close of
business on the Distribution Date (other than any Acquiring Person or any
associate or affiliate of any Acquiring Person) and, thereafter, the separate
Rights Certificates alone will represent the Rights. Except as otherwise
determined by the Board of Directors, only shares of Common Stock issued prior
to the earlier of the Distribution Date or the Expiration Date will be issued
with Rights.

         Subject to the right of the Board of Directors to redeem or exchange
the Rights (as described more fully below), in the event that

         (i)      the Board of Directors determines that a 10% or more
                  stockholder is an Adverse Person, or

         (ii)     a person becomes an Acquiring Person (except pursuant to an
                  offer for all outstanding shares of Common Stock which the
                  independent directors determine to be fair to and otherwise in
                  the best interests of the Company and its stockholders -- a
                  "Fair Offer"),

each holder of a Right will thereafter have the right to receive, upon exercise,
Common Stock (or, in certain circumstances, cash, property or other securities
of the Company or a reduction in the Purchase Price) having a market value of
twice the Purchase Price of the Right. In other words, the Rights holders other
than the Acquiring Person may purchase shares of Common Stock at a 50% discount.

         The Stock Acquisition Date is the date of public announcement that an
Acquiring Person, or any associate or affiliate of an Acquiring Person, has
acquired or obtained the right to acquire beneficial ownership of 15% or more of
the outstanding shares of Common Stock. In the event that, at any time following
the Stock Acquisition Date,

         (i)      the Company is acquired in a merger or other business
                  combination transaction in which the Company is not the
                  surviving corporation or in which the Company's Common Stock
                  is changed into or exchanged for stock or other securities of
                  any other person, cash or any other property (other than a
                  merger which follows, and is at the same price as, a Fair
                  Offer), or

         (ii)     50% or more of the Company's assets or earning power of the
                  Company and its subsidiaries taken as a whole is sold or
                  transferred,

each holder of a Right (except Rights which previously have been voided as set
forth above) shall thereafter have the right to receive, upon exercise, common
stock of the acquiring company having a value equal to two times the exercise
price of the Right. In other words, the Rights holders may purchase the
acquiring company's stock at a 50% discount.

         In general, the Company may redeem the Rights in whole, but not in
part, at any time until ten days following the Stock Acquisition Date (unless
the ten-day period is extended pursuant to the amendment provisions discussed
below), at a price of $0.01 per Right (payable in cash, Common Stock, or other
consideration deemed appropriate by the Board of Directors). The Company may not
redeem the Rights if the Board of Directors has previously declared a person to
be an Adverse Person. After the redemption period has expired, the Company's
right of redemption may be reinstated if an Acquiring Person reduces its
beneficial ownership to 10% or less of the outstanding shares of Common Stock in
a transaction or series of transactions not involving the Company. Immediately
upon the action of the Board of Directors ordering redemption of the Rights, the
Rights will terminate and the only right of the holders of Rights will be to
receive the $0.01 per Right redemption price.

         The Board of Directors of the Company may, at its option, at any time
after any person becomes an Acquiring Person or is determined to be an Adverse
Person, exchange all or part of the then outstanding and exercisable Rights
(excluding Rights held by an Acquiring Person or Adverse Person that have become
null and void) for shares of Common Stock at an exchange ratio of one share of
Common Stock per Right, appropriately adjusted to reflect any stock split, stock
dividend, or similar transaction. Notwithstanding the foregoing, the Board of
Directors cannot effect such exchange at any time after any person, together
with all affiliates and associates of such person, becomes the beneficial owner
of 50% or more of the shares of Common Stock then outstanding. Immediately upon
the action of the Board of Directors of the Company ordering the exchange of any
Rights and without any further action and without any notice, the right to
exercise such Rights will terminate and the only right thereafter of a holder of
such Rights will be to receive that number of shares of Common Stock equal to
the number of such Rights held by such holder multiplied by the exchange ratio
described above. The Company will not issue fractions of shares of Common Stock
or distribute certificates which evidence fractional shares of Common Stock. In
lieu of such

fractional shares of Common Stock, the Company will pay to the registered
holders of the Right certificates with regard to which such fractional shares of
Common Stock would otherwise be issuable an amount in cash equal to the same
fraction of the current market value of a whole share of Common Stock.

         Other than those provisions relating to the principal economic terms of
the Rights (Purchase Price, expiration date, redemption price), any of the
provisions of the Rights Agreement may be amended by the Board of Directors of
the Company prior to the Distribution Date. After the Distribution Date, the
provisions of the Rights Agreement may be amended by the Board of Directors in
order to cure any ambiguity, to make changes which do not adversely affect the
interests of holders of Rights (excluding the interests of any Acquiring Person
or any Adverse Person), or to shorten or lengthen any time period under the
Rights Agreement; provided, however, that no amendment to adjust the time period
governing a redemption shall be made at such time as the Rights are not
redeemable.

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends. While the distribution of the Rights will not
be taxable to stockholders or to the Company, stockholders may, depending upon
the circumstances, recognize taxable income in the event that the Rights become
exercisable for Common Stock (or other consideration) of the Company or for
securities of the acquiring company as set forth above.

         The Purchase Price payable, and the number of Units of Preferred Stock
or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Stock, (ii) if holders of the Preferred Stock are granted certain
rights or warrants to subscribe for Preferred Stock or convertible securities at
less than the current market price of the Preferred Stock, or (iii) upon the
distribution to holders of the Preferred Stock of evidence of indebtedness or
assets (excluding regular quarterly cash dividends) or of subscription rights or
warrants (other than those referred to above).

         A copy of the Rights Agreement will be filed with the Securities and
Exchange Commission as an Exhibit to a Registration Statement on Form 8-A. A
copy of the Rights Agreement is available free of charge from the Company. This
summary description of the Rights does not purport to be complete and is
qualified in its entirety by reference to the Rights Agreement, which is
incorporated herein by reference.
