_____________________________________________________________________________
                                (Title of Class)

ITEM 1.  DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

     GENERAL.  On May 27, 1998 the Board of Directors (the "BOARD") of Success
Bancshares, Inc. (the "COMPANY") declared a dividend of one preferred stock
purchase right (each a "RIGHT") for each outstanding share of the Company's
common stock, par value $.001 per share (the "COMMON STOCK").  The distribution
is payable on August 10, 1998, to holders of record of Common Stock on that
date. In addition, until the Rights become exercisable as described below and in
certain limited circumstances thereafter, the Company will issue one Right for
each share of Common Stock issued after August 10, 1998.  Each Right, when it
becomes exercisable, will entitle its registered holder to purchase from the
Company one one-hundredth of a share of the Company's Series B Junior
Participating Preferred Stock, par value $.001 ("PREFERRED STOCK"), at a price
of $55.00 (the "EXERCISE PRICE"), subject to adjustment.  The description and
terms of the Rights are set forth in a Rights Agreement (the "RIGHTS
AGREEMENT"), dated as of August 1, 1998, between the Company and Harris Trust
and Savings Bank as Rights Agent.

     DISTRIBUTION DATE.  The Rights will not be exercisable until the
Distribution Date (as defined below).  Prior to the Distribution Date, they will
be evidenced by the Common Stock certificates together with a copy of the
Summary of Rights and will be transferred with and only with the Common Stock.
In general, the Rights will separate from the Common Stock and "Distribution
Date" will occur upon the earlier of the following:  (i) the tenth business day
after the first public disclosure that a person or group of affiliated or
associated persons (an "ACQUIRING PERSON") has acquired beneficial ownership of
15% or more of the outstanding Common Stock (the "SHARE ACQUISITION DATE"), or
(ii) the tenth business day after the commencement of a tender or exchange offer
that, if consummated, would result in one person or group beneficially owning
15% or more of the outstanding Common Stock.  A person or group will not be an
Acquiring Person, however, by acquiring beneficial ownership of 15% or more of
the outstanding shares of Common Stock pursuant to a Permitted Offer (as defined
below), and no Distribution Date will occur following the commencement of a
tender offer or exchange offer that is a Permitted Offer.

     "PERMITTED OFFER" means any tender or exchange offer for all of the
outstanding shares of Common Stock of the Company at a price and on terms
determined, prior to the purchase of shares under such tender or exchange offer
by at least a majority of the members of the Board who are Continuing Directors
(as defined below) and who are not officers of the Company, to be appropriate
(taking into account all factors which such Continuing Directors deem relevant,
including, without limitation, prices reasonably obtainable if the Company or
its assets were sold on an orderly basis designed to realize maximum value) and
otherwise in the best interests of the Company and its stockholders (other than
the Person or any Affiliate or Associate thereof on whose behalf or for whose
benefit such tender or exchange offer is being made).

     On the Distribution Date, each Right will become exercisable to purchase
one one-hundredth share of Preferred Stock until August 10, 2008 (the "FINAL
EXPIRATION DATE"), except as described below, unless the Rights are earlier
redeemed.  As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights (the "RIGHTS CERTIFICATES") will be mailed to
holders of record of the Common Stock as of the close of business on the
Distribution Date.  The separate Rights Certificates will thereafter evidence
ownership of the Rights, which will then trade separately from the Common Stock.

     TERMS OF PREFERRED STOCK.   Dividends on the Preferred Stock will be
payable quarterly in an amount for each one-hundredth of a share of Preferred
Stock equal to the greater of (a) $1.00 and (b) 100 times the aggregate per
share amount of any dividend declared on the Company's 


                                       2
<PAGE>   3


Common Stock (the "DIVIDEND MULTIPLE") for such quarter. Unpaid dividends will
cumulate. The Preferred Stock will not be redeemable. Each one-hundredth share
of Preferred Stock will have the same voting rights as one share of Common
Stock.  The Preferred Stock will have a liquidation preference of an amount
equal to the accrued and unpaid dividends thereon, whether or not declared, plus
an amount equal to the Dividend Multiple per hundredth of a share.

     Pursuant to the Rights Agreement, the exercise price payable, and the
number of shares of Preferred Stock or other securities or property issuable,
upon the 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 the holders of the
Preferred Stock of evidences of indebtedness or assets (excluding regular
quarterly cash dividends), assets or subscription rights or warrants (other than
those referred to above).

     The Preferred Stock may be issued in fractions that are integral multiples
of one one-hundredth of a share.  If the Company shall determine not to issue
fractional shares of Preferred Stock upon any exercise of Rights, in lieu
thereof, an adjustment in cash will be made based on the then current market
price of the Preferred Stock.

     EFFECTS OF "TRIGGERING EVENTS."  Under certain circumstances, the Rights
will entitle their holders to purchase securities other than Preferred Stock. If
any person becomes an Acquiring Person other than pursuant to a Permitted Offer,
each holder of a Right (except Rights that are void as set forth below) will
thereafter have the right to receive, upon exercise, Common Stock (or, in
certain circumstances, cash, property or other securities of the Company) having
a value equal to two times the exercise price of the Right.  However, Rights are
not exercisable in any event until such time as the Rights are no longer
redeemable by the Company as set forth below.

     For example, at an exercise price of $55 per Right, each Right not owned by
an Acquiring Person (or by certain related parties) following an event set forth
in the preceding paragraph would entitle its holder to purchase $110 worth of
Common Stock (or other consideration, as noted above) for $55. Assuming that the
Common Stock had a per share value of $13.75 at such time, the holder of each
valid Right would be entitled to purchase eight shares of Common Stock for $55.

     If at any time following the Share Acquisition Date (i) the Company is
acquired in a merger or other business combination transaction in which the
Common Stock is changed or exchanged or in which the Company is not the
surviving corporation (other than a merger that follows a Permitted Offer and
satisfies certain other requirements), or (ii) 50% or more of the Company's
assets or earning power is sold or transferred, each holder of a Right (except
Rights that are void as set forth below) 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.  The events set forth in
this paragraph and in the second preceding paragraph are referred to as the
"TRIGGERING EVENTS."

     Any Rights that are beneficially owned by a person who is or who later
becomes an Acquiring Person (or any affiliate or associate of an Acquiring
Person) or are owned by certain transferees of an Acquiring Person shall become
void from and after the time such person becomes an Acquiring Person.  Thus, any
holder of such a Right (including any subsequent holder) may be unable to
exercise the Right after the occurrence of a Triggering Event.


                                       3
<PAGE>   4
     REDEMPTION.  At any time before the earlier of (i) the tenth business day
following the Share Acquisition Date, or (ii) August 10, 2008, the Board of
Directors of the Company may redeem all, but not less than all, of the then
outstanding Rights for $.01 per Right (the "REDEMPTION PRICE").  However, any
such redemption may be made only with the concurrence of a majority of the
Continuing Directors (as defined below) if it occurs (i) on or after the time
that any person becomes an Acquiring Person or (ii) on or after the date of a
change (resulting from a proxy or consent solicitation) in a majority of the
directors in office at the commencement of such solicitation if any person who
is a participant in such solicitation has stated (or if the Board believes) that
such person may take action to become an Acquiring Person or otherwise to cause
a Triggering Event.

     "CONTINUING DIRECTOR" means (i) any member of the Board, while such a
member, who is not a Restricted Person, or a representative or nominee of a
Restricted Person, and was a member of the Board prior to the date of this
Agreement and (ii) any individual who subsequently becomes a member of the Board
and is not a Restricted Person, or a representative or nominee of a Restricted
Person, if such individual's nomination for election or election to the Board is
recommended or approved by a majority of the Continuing Directors then in
office.

     If the Board elects to redeem the Rights, the Company will announce the
redemption, the right to exercise the Rights will terminate and the only right
of the holders of Rights will be to receive the Redemption Price.

     AMENDMENTS.  At any time before the Distribution Date, the Company may,
without the approval of any holder of the Rights, amend any provision of the
Rights Agreement, except that the Company cannot change the Redemption Price,
the Final Expiration Date, the Exercise Price or the number of one-hundredths of
a share of Preferred Stock for which a Right is exercisable.  At any time after
the Distribution Date, the Company may amend the Rights Agreement without the
approval of the holders of the Rights to cure any ambiguity, to correct any
defective or inconsistent provision, subject to certain exceptions, to shorten
or lengthen any time period (which may require the concurrence of a majority of
the Continuing Directors) or to change a provision in any manner the Company
deems necessary and that does not adversely affect the interests of the holders
of the Rights.  However, the Company can extend the redemption period only if
the Rights are redeemable at the time of the extension.

     OTHER CONSIDERATIONS.  Until a Right is exercised, its holder, as such,
will have no rights as a stockholder of the Company, such as 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 if the Rights become exercisable upon
the occurrence of a Triggering Event as set forth above.

     The Rights have certain anti-takeover effects.  The Rights may cause
substantial dilution to a person or group that attempts to acquire the Company
without conditioning the offer on the Rights being redeemed or a substantial
number of Rights being acquired, and under certain circumstances the Rights
beneficially owned by such person or group may become void.  However, as
described above, no such event will occur in connection with a Permitted Offer.
Moreover, the Rights should not interfere with a merger or other business
combination approved by the Board, because the Board (under certain
circumstances, with the concurrence of the Continuing Directors) may redeem the
Rights for $.01 per Right as described above.

     As of August 1, 1998, there were 2,951,236 shares of Common Stock
outstanding.  Each such share outstanding as of August 10, 1998 will receive one
Right. Prior to the Distribution Date, the Company will issue one Right for each
such share of Common Stock issued after August 10, 1998.  Ninety thousand
(90,000) shares of Preferred Stock will initially be reserved for issuance upon
exercise of the Rights.

     The terms of the Rights are set forth in the Rights Agreement.  The form of
Rights Agreement, which includes, as Exhibit A, the form of Certificate of
Designations of the Preferred Stock, as Exhibit B, the form of Rights
Certificate, and, as Exhibit C, a Summary of the Rights, is included as Exhibit
1 to this Registration Statement on Form 8-A and is incorporated herein by
reference.  The foregoing description of the Rights does not purport to be
complete and is qualified in its entirety by reference to the Rights Agreement.

                                RIGHTS AGREEMENT


     This Rights Agreement is entered into as of August 1, 1998 (this
"AGREEMENT") between Success Bancshares, Inc., a Delaware corporation (the
"COMPANY"), and Harris Trust and Savings Bank, an Illinois banking corporation
(the "RIGHTS AGENT").

                               R E C I T A L S :

     A.   The Board of Directors of the Company desires to provide all
stockholders of the Company with the opportunity to benefit from the long-term
prospects and value of the Company and to ensure that all such stockholders
receive fair and equal treatment in the event of any proposed takeover of the
Company; and

     B.   On May 27, 1998, the Board of Directors of the Company (the "BOARD")
authorized and declared a dividend of one preferred stock purchase right
(individually a "RIGHT" and collectively the "RIGHTS") for each share of Common
Stock (as hereinafter defined) of the Company outstanding at the Close of
Business on the determined record date (the "RECORD DATE"), each Right
representing the right to purchase one one-hundredth of a Preferred Share (as
hereinafter defined) upon the terms and subject to the conditions herein after
set forth, and contemplates that one Right will be issued with respect to each
share of Common Stock which shall become outstanding after the Record Date and
prior to the earlier of the Redemption Date and the Final Expiration Date (as
such terms are hereinafter defined), including any shares of Common Stock
issued by reason of the exercise of any option, warrant, right (other than the
Rights) or conversion or exchange privilege contained in any option, warrant,
right (other than the Rights) or convertible or exchangeable security issued by
the Company prior to the Distribution Date, unless the Board shall expressly
provide to the contrary at the time of issuance of any such option, warrant,
right or convertible or exchangeable security.

                                C L A U S E S :

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

     SECTION 1. CERTAIN DEFINITIONS.  For all purposes of this Agreement, unless
the context otherwise requires, the following terms shall have the respective
meanings set forth below:

     "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 of the Company then outstanding, but
shall not include (i) the Company, (ii) any Subsidiary of the Company, (iii)
any employee benefit plan or other compensation program or arrangement of the
Company or of any such Subsidiary or (iv) any Person holding such shares of
Common Stock for or pursuant to the terms of any such plan, program or
arrangement (the Persons specified in clauses (i) through (iv) being
hereinafter collectively called "EXEMPT PERSONS").  Notwithstanding the
preceding sentence, no Person shall become an "Acquiring Person" as the result
of (a) being a Beneficial Owner of 15% or more of the outstanding shares of
Common Stock of the Company on the date of this 



                                      1


<PAGE>   5


Agreement, (b) an acquisition by the Company of shares of its Common Stock
which, by reason of reducing the number of its then outstanding shares of Common
Stock, increases the percentage of its then outstanding shares of Common Stock
Beneficially Owned by such Person to 15% or more (c) such Person becoming the
Beneficial Owner of 15% or more of the then outstanding shares of Common Stock
pursuant to a Permitted Offer, or (d) the acquisition by such Person of
newly-issued shares of Common Stock of the Company directly from the Company (it
being understood that a purchase from an underwriter or other intermediary is
not directly from the Company); provided, however, that if such Person shall,
after such acquisition by the Company, become the Beneficial Owner of any
additional shares of Common Stock of the Company, then such Person shall be
deemed to be an "Acquiring Person"; provided, further, however, that any
transferee from such Person who becomes a Beneficial Owner of 15% or more of the
shares of Common Stock of the Company then outstanding shall nevertheless be
deemed to be an "Acquiring Person."  Notwithstanding the foregoing, if the Board
determines in good faith that a Person who would otherwise be an "Acquiring
Person," as defined pursuant to the foregoing provisions of this paragraph, has
become such inadvertently, and such Person divests as promptly as practicable
(and in any event within ten business days after notification by the Company) a
sufficient number of shares of Common Stock so that such Person w no longer be
an Acquiring Person, as defined pursuant to the foregoing provisions of this
paragraph, then such Person shall not be deemed to be an "Acquiring Person" for
any purpose of this Agreement.

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

         "Beneficial Owner" (including the terms "Beneficially Own" and
"BENEFICIAL OWNERSHIP"), when used with respect to any Person, shall be deemed
to include any securities which:

         (i)   such Person or any of such Person's Affiliates or Associates
     beneficially owns, directly or indirectly (determined as provided in Rule
     13d-3, as in effect on the date of this Agreement, under the Exchange Act);

         (ii)  such Person or any of such Person's Affiliates or Associates,
     directly or indirectly, has:

               (A)  the right to acquire (whether such right is exercisable
         immediately or only after the passage of time or upon the satisfaction
         of any conditions, or both) pursuant to any written or oral agreement,
         arrangement or understanding (other than customary agreements with and
         among underwriters and selling group members with respect to a bona
         fide public offering of securities), upon the exercise of any options,
         warrants, rights (other than the Rights) or conversion or exchange
         privileges or otherwise; provided, however, that a Person shall not be
         deemed the Beneficial Owner of, or to Beneficially Own: (I) securities
         tendered pursuant to a tender or exchange offer made by or on behalf of
         such Person or any of such Person's Affiliates or Associates until such
         tendered securities are accepted for purchase or exchange or (II)
         securities issuable upon exercise of the Rights at any time prior to
         the Distribution Date; or




                                      2


<PAGE>   6

execute, the Rights Agent shall countersign and the Company shall deliver or
cause to be delivered (or the Rights Agent shall, if requested, deliver at the
expense of the Company), by first-class mail, postage prepaid, to each record
holder of shares of Common Stock of the Company as of the Close of Business on

the earliest of the Distribution Date, the Redemption Date and the Final

         (c)  Any stock certificate for shares of Common Stock of the Company
which shall be delivered by or on behalf of the Company (including, without
limitation, stock certificates for shares of Common Stock which are reacquired
by the Company and then transferred) after the Record Date and prior to the
earliest of the Distribution Date, the Redemption Date and the Final Expiration
Date shall have impressed, printed or written thereon, or otherwise affixed
thereto, the following legend:

         "This certificate also evidences and entitles the holder hereof
     to certain Rights as set forth in the Rights Agreement dated as of
     August 1, 1998 (the "RIGHTS AGREEMENT") between Success Bancshares,
     Inc. (the "COMPANY") and Harris Trust and Savings Bank, as Rights
     Agent, the terms, provisions and conditions of which are
     incorporated herein by reference and made a part hereof.  The
     Rights Agreement is on file at the principal office of Company and
     the principal office of such Rights Agent, and the Company will
     mail to the holder of this certificate a copy without charge after
     receipt of a written request therefor.  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.  Under certain circumstances, as set
     forth in the Rights Agreement, Rights Beneficially Owned by a
     Restricted Person (as such terms are defined in the Rights
     Agreement), or by specified transferees from a Restricted Person,
     shall be or may become void."

Each stock certificate containing the foregoing legend, until the earliest of
the Distribution Date, the Redemption Date and the Final Expiration Date, shall
be deemed also to constitute a certificate for the Rights associated with the
shares represented thereby, and the registered holder of such shares shall also
be the registered holder of the associated Rights.  Until the earliest of the
Distribution Date, the Redemption Date and the Final Expiration Date, the
surrender for transfer of any such stock certificate shall also constitute the
transfer of the Rights associated with the shares of Common Stock represented
thereby.  The omission of the foregoing legend shall not in any manner
whatsoever affect the application or interpretation of Section 7(d).

         (d)  In the event that the Company shall reacquire any shares of its
Common Stock after the Record Date and prior to the Distribution Date, the
Rights associated with such shares shall be deemed canceled and retired, the
Company not being entitled to exercise any Rights associated with shares of its
Common Stock which are no longer outstanding.

         SECTION 4. FORM OF RIGHTS CERTIFICATES.  (a) The Rights Certificates
(including the forms of election to purchase and assignment to be set forth on
the reverse side thereof) shall be in substantially the form attached hereto as
Exhibit B and may have such marks of identification or designation and such
legends, summaries or endorsements set forth thereon as the Company may deem
appropriate and are not inconsistent with the provisions of this Agreement, or
as may be required to conform to customary practice or to comply with any
applicable law or 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.  Subject to Sections 11 and 22, the Rights Certificates, whenever
distributed, shall be dated as of the Record Date (or, in the case of Rights
with respect to shares of Common Stock issued or becoming outstanding after the
Record Date, the same date as the stock certificate evidencing such shares),
shall entitle the holders thereof to purchase such number of one one-hundredths
of a 


                                      7


<PAGE>   11


Preferred Share at the Exercise Price as shall be set forth therein, but the
number of such one one-hundredths of a Preferred Share or other securities and
the Exercise Price thereof shall be subject to adjustment as provided herein.

         (b)  Any Rights Certificate issued pursuant to Section 3(a) or Section
22 that represents Rights Beneficially Owned by: (i) a Restricted Person, (ii) a
transferee from a Restricted Person who becomes a transferee after the Acquiring
Person or Adverse Person becomes such or (iii) a transferee from a Restricted
Person who becomes a transferee prior to or concurrently with the Acquiring
Person becoming such and receives such Rights pursuant to either (A) a transfer
(whether or not for consideration) from such Acquiring Person (or any Affiliate
or Associate thereof) to holders of equity interests in such Acquiring Person
(or any such Affiliate or Associate) or to any Person with whom such Acquiring
Person (or any such Affiliate or Associate) has any continuing written or oral
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 the avoidance of Section
7(d), and any Rights Certificate issued pursuant to Section 6, 11 or 22 upon the
transfer, exchange, replacement or adjustment of any other Rights Certificate
referred to in this sentence, shall have deleted therefrom the second sentence
of the legend on the Form of Rights Certificate attached hereto as Exhibit B
and, in lieu thereof, shall contain the following two sentences:

         "The Rights represented by this Rights Certificate are or were
     Beneficially Owned by a Restricted Person (as such term is defined
     in such Agreement).  This Rights Certificate and the Rights
     represented hereby shall be or may become void under the
     circumstances specified in Section 7(d) of such Agreement."

The Company shall give prompt written notice to the Rights Agent after becoming
aware of the existence and identity of any Restricted Person.  The failure to
insert the foregoing sentences on any such Rights Certificate or any defect
therein shall not in any manner whatsoever affect the application or
interpretation of Section 7(d).  The Company shall specify to the Rights Agent
in writing which Rights Certificates are to be so legended.

         SECTION 5. COUNTERSIGNATURE AND REGISTRATION.  (a) The Rights
Certificates shall be executed on behalf of the Company by its Chairman of the
Board, its President, or any of its Vice Presidents, either manually or by
facsimile signature, and shall have affixed thereto the Company's seal or a
facsimile thereof attested by its Secretary or any of its Assistant Secretaries,
either manually or by facsimile signature.  The Rights Certificates shall be
manually countersigned by an authorized signatory of the Rights Agent and shall
not be valid or obligatory for any purpose unless so countersigned.  In case any
officer of the Company who shall have executed any Rights Certificate or who
shall have attested the Company's seal thereon shall cease to be such officer of
the Company before such Rights Certificate shall have been countersigned by an
authorized signatory of the Rights Agent and issued and delivered by or on
behalf of the Company, such Rights Certificate, nevertheless, may be
countersigned by the Rights Agent and issued and delivered by or on behalf of
the Company with the same force and effect as though the individual who executed
such Rights Certificate or who attested the Company's seal thereon had not
ceased to be such officer; and any Rights Certificate may be executed on behalf
of the Company and the Company's seal may be attested by any individual who, at
the actual date of such execution or attestation, shall be a proper officer of
the 


                                      8


<PAGE>   12


Company, although at the date of execution of this Rights Agreement such person
was not such an officer.

         (b)  After the Distribution Date, the Rights Agent shall keep or cause
to be kept, at its principal office, 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 Rights Certificate, the date of each Rights
Certificate and (if required by the Company) the date of countersignature by the
Rights Agent.

         SECTION 6. TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF RIGHTS
CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHTS CERTIFICATES.  (a)
Subject to Sections 4(b), 7(d) and 14, at any time after the Close of Business
on the Distribution Date and prior to the Close of Business on the earlier of
the Redemption Date and the Final Expiration Date, any Rights Certificate (other
than any Rights Certificate which shall have been exchanged pursuant to Section
24) may be transferred, split up, combined or exchanged for one or more other
Rights Certificates, entitling the registered holder to purchase the same number
of one one-hundredths of a Preferred Share (or after a Triggering Event, the
securities, cash and other property purchasable in lieu thereof) as the Rights
Certificate or Rights Certificates surrendered entitled such registered holder
to purchase.  Any registered holder desiring to transfer, split up, combine or
exchange one or more Rights Certificates shall make such request in a writing
delivered to the Rights Agent, and shall surrender the Rights Certificates to be
transferred, split up, combined or exchanged, with the form of assignment on the
reverse side thereof duly executed, together with such signature guarantees and
other documentation as the Rights Agent may reasonably request, at the principal
office of the Rights Agent.  Neither the Rights Agent nor the Company shall be
obligated to take any action whatsoever with respect to the transfer of any such
surrendered Right Certificate until the registered holder shall have completed
and signed the certificate contained in the form of assignment on the reverse
side of such Right 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 Company shall prepare and execute, the Rights Agent shall
countersign and the Company shall deliver or cause to be delivered (or the
Rights Agent shall, if requested, deliver), subject to Section 4(b), 7(d) and
14, to the person entitled thereto one or more Rights Certificates as so
requested.  The Company may require payment of a sum sufficient to cover any tax
or governmental charge that may be imposed in connection with any transfer,
split up, combination or exchange of Rights Certificates and reimbursement to
the Company and the Rights Agent of all reasonable expenses incidental thereto.

         (b)  Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Rights Certificate, and, in the case of loss, theft or destruction, of
indemnity or security reasonably satisfactory to them or, in the case of
mutilation, upon surrender to the Rights Agent of the mutilated Rights
Certificate, and, at the Company's request, reimbursement to the Company and the
Rights Agent of all reasonable expenses incidental thereto, the Company shall
prepare and execute, the Rights Agent shall countersign and the Company shall
deliver or cause to be delivered (or the Rights Agent shall, if requested,
deliver) to the registered holder thereof a new Rights Certificate of like tenor
in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated.

         SECTION 7. EXERCISE OF RIGHTS; EXERCISE PRICE; EXPIRATION DATE OF
RIGHTS. (a)  Subject to Section 7(d), the registered holder of any Rights
Certificate may exercise the Rights evidenced thereby (except as otherwise

"FINAL EXPIRATION DATE"), (ii) the time at which the Rights are redeemed as

office, accompanied by payment (as provided in subsection (c) of this Section 7)
of the Exercise Price for each one one-hundredth of a Preferred Share (or after
a Triggering Event, the securities, cash and other property purchasable in lieu
thereof) as to which the surrendered Rights are then being exercised.

         (b)  The price (the "EXERCISE PRICE") for each one one-hundredth of a
Preferred Share purchased upon exercise of the Rights shall initially be $55.00,
shall be subject to adjustment from time to time as provided in Sections 11 and
13 and shall be payable in lawful money of the United States of America in
accordance with subsection (c) of this Section 7.

         (c)  Upon receipt of a Rights Certificate representing then exercisable
Rights, with the form of election to purchase and certification of status on the
reverse side thereof duly executed, together with such signature guarantees and
other documentation as the Rights Agent may reasonably request, accompanied by
payment of the Exercise Price for the number of one one-hundredths of a
Preferred Share (or after a Triggering Event, the securities, cash and other
property purchasable in lieu thereof) being purchased, plus the amount of any
applicable transfer tax (as determined by the Rights Agent) required to be paid
by the holder of such Rights Certificate in accordance with Section 9, the
Rights Agent shall, subject to the terms and conditions of this Agreement,
thereupon promptly (i) requisition from any transfer agent for the Preferred
Shares (or, if the Rights Agent is such a transfer agent, make available) stock
certificates for the number of one one-hundredths of a Preferred Share being
purchased, the Company hereby irrevocably authorizing any such transfer agent to
comply with all such requests, (ii) if the Company shall have elected to deposit
the Preferred Shares issuable upon exercise of the Rights with a depository
agent, requisition from the depository agent depository receipts for the number
of one one-hundredths of a Preferred Share being purchased (in which case stock
certificates for the Preferred Shares represented by such depository receipts
shall be deposited by the transfer agent for the Preferred Shares with the
depository agent), the Company hereby irrevocably authorizing any such
depository agent to comply with all such requests, (iii) after a Triggering
Event, requisition or obtain from the appropriate Person or Persons such
securities, cash and other property as may then be purchasable in lieu of
Preferred Shares, the Company hereby irrevocably authorizing all such requests,
(iv) when appropriate, requisition from the Company the amount of cash to be
paid in lieu of the issuance of any fractional share in accordance with Section
14 and (v) promptly after receipt of such stock certificates, depository
receipts, securities, cash and/or other property, cause the same to be delivered
to or upon the order of the registered holder of such Rights Certificate,
registered (when appropriate) in such name or names as may be designated by such
registered holder.

         (d)  Notwithstanding anything in this Agreement to the contrary, from
and after the first occurrence of any Section 11(a)(ii) Event, any Rights
Beneficially Owned by: (i) a Restricted Person, (ii) a transferee from a
Restricted Person who becomes a transferee after the Acquiring Person becomes
such or (iii) a transferee from a Restricted Person who becomes a transferee
prior to or concurrently with the Acquiring Person becoming such and receives
such Rights pursuant to either (A) a transfer (whether or not for consideration)
from such Acquiring Person (or any Affiliate or Associate thereof) to holders of
equity interests in such Acquiring Person (or any such Associate or Affiliate)
or to any Person with whom such Acquiring Person (or any such Associate or
Affiliate) has any continuing written or oral 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 the avoidance of this Section 7(d), shall be void
without any further action; and no holder of such Rights shall have any rights
whatsoever with respect to such Rights, whether under any provision of this
Agreement or otherwise, from and after such first occurrence. The Company shall
use all reasonable efforts to ensure that the provisions of this Section 7(d)
and Section 4(b) are complied with, but shall have no liability to any holder of
the Rights Certificates or to any other Person as a result of the Company's
failure to make any applicable finding or determination with respect to any
Restricted Person, or any transferee therefrom.

         (e)  Notwithstanding subsection (a) of this Section 7, a Right may be
exercised by the holder thereof on or after the Distribution Date and prior to
the receipt of the associated Rights Certificate by notifying the Rights Agent
in writing and furnishing to the Rights Agent such information and evidence as
to such election as the Rights Agent may reasonably request; provided, however,
that the Rights Agent shall not be required to take any of the actions specified
in subsection (c) of this Section 7 until such holder shall have fully satisfied
the applicable requirements specified therein.

         (f)  Neither the Rights Agent nor the Company shall be obligated to
undertake any action with respect to any Rights or Rights Certificate upon the
purported exercise or transfer thereof unless the registered holder thereof
shall have (i) completed and signed the certification of status following the
form of election to purchase or the form of assignment, as the case may be, set
forth on the reverse side of the Rights Certificate surrendered for such
exercise or transfer and (ii) provided such additional evidence as to the
identity of the Beneficial Owner (or former Beneficial Owner) thereof or the
Affiliates or Associates thereof as the Company shall reasonably request.

         (g)  In case the registered holder of any Rights Certificate shall
exercise less than all of the Rights evidenced thereby, then, subject to the
provisions of Section 14, a new Rights Certificate evidencing the Rights
remaining unexercised shall be prepared and executed by the Company and
countersigned and delivered by the Rights Agent to the registered holder of such
surrendered Rights Certificate or to such registered holder's duly authorized
assigns.

         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 to any of its
agents, be delivered to the Rights Agent for cancellation or in canceled form
or, if surrendered to the Rights Agent, shall be canceled by it; and no Rights
Certificates shall be issued in lieu thereof except as expressly permitted by
this Agreement.  The Company shall deliver to the Rights Agent for cancellation,
and the Rights 



                                     11


<PAGE>   15


Agent shall cancel, any other Rights Certificate purchased or reacquired 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 deliver a
certificate of the destruction thereof to the Company.

         SECTION 9. RESERVATION AND AVAILABILITY OF PREFERRED SHARES.  (a)  The
Company covenants and agrees that it will cause to be reserved and kept
available out of its authorized and unissued Preferred Shares, (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 any authorized and issued
shares held in its treasury), the number of Preferred Shares (and, following the
occurrence of a Triggering Event, Common Stock and/or other securities) required
to permit the exercise in full of all outstanding Rights.

         (b)  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 Preferred Share
delivered upon exercise of the Rights shall, at the time of delivery of the
stock certificates therefor in accordance with Section 7(c) (including the
receipt of payment of the Exercise Price), be duly and validly authorized and
issued and fully paid and nonassessable.

         (c)  The Company covenants and agrees that it will use its best efforts
to cause, from and after such time as the Rights shall become exercisable, all
Preferred Shares issued or reserved for issuance to be listed, upon official
notice of issuance, on the principal national securities exchange, if any, on
which its Common Stock is listed or, if the principal market for Common Stock is
not on any national securities exchange, to be eligible for quotation on the
National Association of Securities Dealers Automated Quotation System ("NASDAQ")
or any successor thereto or other comparable quotation system.

         (d)  The Company covenants and agrees that it will use its best efforts
to (i) file, as soon as practicable after the occurrence of any Section
11(a)(ii) Event for which the consideration to be delivered by the Company upon
exercise of the Rights has been determined in accordance with Section
11(a)(iii), or as soon as required by law after the Distribution Date, as the
case may be, a registration statement on an appropriate form under the
Securities Act with respect to the securities purchasable upon exercise of the
Rights, (ii) cause such registration statement to become effective as soon as
practicable after such filing and (iii) cause such registration statement to
remain effective (with a prospectus which at all times meets the requirements of
the Securities Act) until the earliest of (A) the date as of which the Rights
are no longer exercisable for such securities, (B) the Redemption Date and (C)
the Final Expiration Date.  The Company further covenants and agrees that it
will take such action as may be appropriate under, and which will ensure
compliance with, the securities or "blue sky" laws of such jurisdictions as may
be necessary or appropriate in connection with the exercisability of the Rights.
The Company may temporarily suspend, for not more than 90 days after the
applicable date specified in the first sentence of this subsection (d), the
exercisability of the Rights in order to prepare and file such registration
statement and permit it to become effective and to complete such securities or
"blue sky" law action.  Upon such suspension, the Company shall issue a public
announcement stating that the exercisability of the Rights has been temporarily
suspended, and the Company shall also issue a public announcement at such time
as the suspension shall no longer be in effect.  Failure of the Company to
notify the Rights Agent of any such suspension shall not affect the
effectiveness thereof. Notwithstanding any provision of this Agreement to the
contrary, the Rights shall not be exercisable in any 



                                     12


<PAGE>   16


jurisdiction unless the requisite qualification or exemption in such
jurisdiction shall have been effected.  Until otherwise notified in writing by
the Company, the Rights Agent may assume that each purported exercise of the
Rights is permitted by this Agreement and by applicable law, and the Rights
Agent shall not be liable for acting in reliance upon such assumption.

         (e)  The Company covenants and agrees that, subject to Section 6, it
will pay when due and payable any and all federal and state original issue or
transfer taxes and charges which may be payable in respect of the issuance or
delivery of the Rights or the Rights Certificates or of any stock certificate
for Preferred Shares (or Common Stock and/or other securities, as the case may
be) issued upon exercise of the Rights.  The Company shall not, however, be
required to pay any transfer tax which may be payable in respect of any transfer
or delivery of any Rights Certificate to a Person other than, or the issuance of
any stock certificate for Preferred Shares (or Common Stock and/or other
securities, as the case may be) upon exercise of any of the Rights represented
by such Rights Certificate in a name other than, the registered holder of such
Rights Certificate or to issue or deliver any Rights Certificate or stock
certificate for Preferred Shares upon such transfer or exercise until any such
tax shall have been paid (any such tax being payable by the holder of such
Rights Certificate at the time of surrender thereof) or until it has been
established to the Company's reasonable satisfaction that no such tax is due.

         (f)  After a Triggering Event, the provisions of this Section 9 shall
apply, to the extent applicable and appropriate, to all shares of capital stock
and other securities then purchasable upon exercise of the Rights.

         SECTION 10. RECORD DATE OF PREFERRED SHARE OWNERSHIP.  The Person in
whose name any stock certificate for Preferred Shares (or Common Stock and/or
other securities, as the case may be) is issued upon exercise of any of the
Rights shall for all purposes be deemed to have become the holder of record of
the Preferred Shares (or Common Stock and/or other securities, as the case may
be) represented thereby on, and such stock certificate shall be dated, the date
upon which the Rights Certificate evidencing such Rights was duly surrendered to
the Rights Agent with proper payment of the Exercise Price (and all applicable
transfer taxes, if any); provided, however, that if the date of such surrender
and payment shall be a date upon which the registry books of the transfer agent
for the Preferred Shares are closed, such Person shall be deemed to have become
the record holder of such Preferred Shares on, and such stock certificate shall
be dated, the next succeeding Business Day on which such registry books 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 any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.

         SECTION 11. ADJUSTMENT OF EXERCISE PRICE, NUMBER AND KIND OF SHARES AND
NUMBER OF RIGHTS.  The Exercise Price, the number and kind of shares of capital
stock for which each Right is exercisable 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 that the Company shall at any time after the date
of this Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) 


                                     13


<PAGE>   17


subdivide the outstanding Preferred Shares into a greater number of Preferred
Shares, (C) combine or consolidate the outstanding Preferred Shares into a
smaller number of Preferred Shares or (D) issue any shares of capital stock of
any class in a reclassification of the Preferred Shares (including any such
reclassification in connection with a combination 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(d), the Exercise Price in effect at the
Close of Business on the record date for such dividend or at the effective time
of such subdivision, combination, consolidation or reclassification, and the
number and kind of shares of capital stock issuable upon exercise of the Rights
at such date or time, shall be proportionately adjusted so that the registered
holder of each Right exercised after such date or time shall be entitled to
receive the aggregate number and kind of shares of capital stock which, if such
Right had been exercised immediately prior to such date or time and at a time
when the registry books of the transfer agent for the Preferred Shares were
open, such registered holder would have been entitled to receive by reason of
such dividend, subdivision, combination, consolidation or reclassification;
provided, however, that in no event shall the consideration to be paid upon the
exercise of one Right be less than the aggregate par value of the shares of
capital stock of the Company issuable upon the exercise thereof.  If an event
shall occur which would require an adjustment under both this paragraph (i) and
paragraph (ii) of this subsection (a), the adjustment provided for in this
paragraph (i) shall be in addition to, and shall be made prior to, any
adjustment required pursuant to such paragraph (ii).

         (ii)  Subject to Section 24, in the event that any Person, either alone
or together with its Affiliates and Associates, shall become an Acquiring
Person, proper provision shall be made so that the registered holder of each
Right, except as otherwise provided in Section 7(d), shall thereafter have the
right to receive, upon exercise thereof and payment of an amount equal to the
then current Exercise Price, in accordance with this Agreement, in lieu of
Preferred Shares, the number of shares of Common Stock determined by (x)
multiplying the then current Exercise Price by the number of one one-hundredths
of a Preferred Share for which a Right was exercisable immediately prior to a
first occurrence Section 11(a)(ii) Event and (y) dividing such product by 50% of
the Fair Market Value (determined as provided in subsection (d) of this Section
11) of one share of Common Stock on the date of such occurrence (such number of
shares, the "ADJUSTMENT SHARES").

         (iii) In the event that there shall not be sufficient treasury shares
or authorized but unissued (and unreserved) Common Shares to permit the exercise
in full of the Rights in accordance with the foregoing subparagraph (ii) and the
Rights become so exercisable (and the Board has determined to make the Rights
exercisable into fractions of a Preferred Share), notwithstanding any other
provision of this Agreement, to the extent necessary and permitted by applicable
law, each Right shall thereafter represent the right to receive, upon exercise
thereof at the then current Purchase Price in accordance with the terms of this
Agreement, (x) a number of (or fractions of) Common Shares (up to the maximum
number of Common Shares which may permissibly be issued) and (y) a number of one
one-hundredths of a Preferred Share or a number of, or fractions of other equity
securities of the Corporation (or, in the discretion of the Board of Directors,
debt) which the Board of Directors of the Corporation has determined to have the
same aggregate current market value (determined pursuant to Section 11(d)(i) and
(ii) hereof, to the extent applicable,) as one Common Share (such number of, or
fractions of, Preferred Shares, debt, or other equity securities or debt of the
Corporation being referred to as a "CAPITAL STOCK EQUIVALENT"), equal in the
aggregate to the number of Adjustment Shares;



                                     14


<PAGE>   18


provided, however, if sufficient Common Shares and/or capital stock equivalents
are unavailable, then the Company shall, to the extent permitted by applicable
law, take all such action as may be necessary to authorize additional Common
Shares or capital stock equivalents for issuance upon exercise of the Rights,
including the calling of a meeting of stockholders; and provided, further,
however, that if the Company is unable to cause sufficient Common Shares and/or
capital stock equivalents to be available for issuance upon exercise in full of
the Rights, then each Right shall thereafter represent the right to receive the
Adjusted Number of Shares upon exercise at the Adjusted Purchase Price (as such
terms are hereinafter defined).  As used herein, the term "Adjusted Number of
Shares" shall be equal to that number of (or fractions of) Common Shares (and/or
capital stock equivalents) equal to the product of (x) the number of Adjustment
Shares and (y) a fraction, the numerator of which is the number of Common Shares
(and/or capital stock equivalents) available for issuance upon exercise of the
Rights and the denominator of which is the aggregate number of Adjustment Shares
otherwise issuable upon exercise in full of all Rights, assuming there were a
sufficient number of Common Shares available (such fraction being referred to as
the "PRORATION FACTOR").  The "Adjusted Purchase Price" shall mean the product
of the Purchase Price and the Proration Factor. The Board of Directors may, but
shall not be required to, establish procedures to allocate the right to receive
Common Shares and capital stock equivalents upon exercise of the Rights among
holders of Rights.

         (b)  In the event that the Company shall fix a record date for the
making of any distribution to all registered holders of Preferred Shares of
options, warrants or rights entitling them (for a period expiring not later than
45 calendar days after such record date) to subscribe for or purchase Preferred
Shares (or shares of capital stock of any class of the Company having the same
(or more favorable) powers, preferences and rights as the Preferred Shares
("EQUIVALENT PREFERRED SHARES")), or securities convertible into or exchangeable
for Preferred Shares or Equivalent Preferred Shares, at a price per Preferred
Share or per Equivalent Preferred Share (or having a conversion or exchange
price per share, in the case of securities convertible into or exchangeable for
Preferred Shares or Equivalent Preferred Shares) less than the Fair Market Value
(determined as provided in subsection (d) of this Section 11) of one Preferred
Share on such record date, the Exercise Price to be in effect after such record
date shall be determined by multiplying the Exercise Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
number of Preferred Shares outstanding on such record date, plus the number of
Preferred Shares which the aggregate offering price of the total number of
Preferred Shares and/or Equivalent Preferred Shares so to be offered (and/or the
aggregate initial conversion or exchange price, in the case of convertible or
exchangeable securities so to be offered) would purchase at such Fair Market
Value, and the denominator of which shall be the number of Preferred Shares
outstanding on such record date, plus the total number of Preferred Shares
and/or Equivalent Preferred Shares so to be offered (and/or into or for which
the convertible or exchangeable securities so to be offered are initially
convertible or exchangeable); provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
the exercise thereof.  In case all or part of such subscription price may be
paid in a form other than cash, the value of such non-cash consideration shall
be its Fair Market Value (determined as provided in such subsection (d).
Preferred Shares owned by or held for the account of the Company shall not be
deemed outstanding for the purpose of any computation provided for in this
subsection (b).  The adjustment required by this subsection (b) shall be made
successively whenever such a record date is fixed; and in the event that such
distribution is not so made, the Exercise Price shall be 


                                     15


<PAGE>   19


adjusted to the Exercise Price which would have been in effect if such record
date had not been fixed.

         (c)  In the event that the Company shall fix a record date for the
making of any distribution to all registered holders of Preferred Shares
(including any such distribution made in connection with a combination or merger
in which the Company is the continuing or surviving corporation) of cash (other
than a regular quarterly cash dividend), options, warrants, rights (other than
those referred to in subsection (b) of this Section 11), securities, evidences
of indebtedness or other property (excluding any dividend payable in Preferred
Shares, but including any dividend payable in other shares of capital stock),
the Exercise Price to be in effect after such record date shall be determined by
multiplying the Exercise Price in effect immediately prior to such record date
by a fraction, the numerator of which shall be the Fair Market Value (determined
as provided in subsection (d) of this Section 11) of one one-hundredth of a
Preferred Share on such record date, less the Fair Market Value (as so
determined) of the cash, options, warrants, rights, securities, evidences of
indebtedness or other property so to be distributed and properly attributable to
one one-hundredth of a Preferred Share, and the denominator of which shall be
such Fair Market Value of one one-hundredth of a Preferred Share; provided,
however, that in no event shall the consideration to be paid upon the exercise
of one Right be less than the aggregate par value of the shares of capital stock
of the Company issuable upon the exercise thereof.  The adjustment required by
this subsection (c) shall be made successively whenever such a record date is
fixed; and in the event that such distribution is not so made, the Exercise
Price shall be adjusted to the Exercise Price which would have been in effect if
such record date had not been fixed.

         (d)  For the purpose of any computation required under this Agreement,
"Fair Market Value," when used with respect to Preferred Shares or shares of
Common Stock or other capital stock of any class (collectively, a "STOCK"), to
any option, warrant, right or other security or evidence of indebtedness
(collectively, a "SECURITY") or to any other property, shall be determined as
provided in this subsection (d):

         (i)   In the case of any Stock or Security which is publicly traded,
     the Fair Market Value on any date shall be deemed to be the average of the
     daily closing prices per share of such Stock or per unit of such Security
     for the 30 consecutive Trading Days immediately prior to such date;
     provided, however, that in the event that the Fair Market Value per share
     of any Stock is determined during a period commencing after the public
     announcement by its issuer of (A) a dividend or distribution on such Stock
     payable in shares of such Stock or securities convertible into or
     exchangeable for shares of such Stock or (B) a subdivision, combination,
     consolidation or reclassification of such Stock, and ending prior to the
     expiration of the 30 Trading Days after the ex-dividend date for such
     dividend or distribution, or the record date for such subdivision,
     combination, consolidation or reclassification, then, in each such case,
     the Fair Market Value of such Stock shall be properly 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 shall take 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 such Stock or Security is not listed or admitted
     to trading on the New York Stock Exchange, as reported in the principal
     consolidated transaction reporting system with respect to securities listed
     or admitted to trading on the principal national securities 


                                     16


<PAGE>   20


     exchange on which such Stock or Security is listed or admitted to trading;
     or if such Stock or Security is not listed or admitted to trading on any
     national securities exchange, the last quoted price or, if not so quoted,
     the average of the last quoted high bid and low asked prices in the
     over-the-counter market, as reported by NASDAQ or any other similar system
     then in use; or if on any such day no bid for such Stock or Security is
     quoted by any such organization, the average of the closing bid and asked
     prices, as furnished by a professional market maker making a market in such
     Stock or Security selected by the Board.  If during any relevant period no
     market maker is making a market in such Stock or Security, its Fair Market
     Value on a specified date shall be determined reasonably and with utmost
     good faith to the holders of the Rights by the Board; provided, however,
     that if at the time of such determination there shall be an Acquiring
     Person, the Fair Market Value of such Stock or Security on such date shall
     be determined by a nationally recognized investment banking firm selected
     by the Board, which determination shall be described in a statement filed
     with the Rights Agent and shall be binding on the Company, the Rights Agent
     and the holders of the Rights. The term "Trading Day" shall mean a day on
     which the principal national securities exchange on which such Stock or
     Security is listed or admitted to trading is open for the transaction of
     business or, if such Stock or Security is not listed or admitted to trading
     on any national securities exchange, a Business Day.

         (ii)  In the case of any Stock or Security which is not publicly
     traded, the Fair Market Value on any date shall be the fair value per share
     of such Stock or per unit of such Security as determined reasonably and
     with utmost good faith to the holders of the Rights by the Board; provided,
     however, that if at the time of such determination there shall be an
     Acquiring Person, the Fair Market Value of such Stock or Security on such
     date shall be determined by a nationally recognized investment banking firm
     selected by the Board, which determination shall be described in a
     statement filed with the Rights Agent and shall be binding on the Company,
     the Rights Agent and the holders of the Rights.

         (iii) In the case of any property which is not a Stock or a Security,
     the Fair Market Value on any date shall be determined reasonably and with
     utmost good faith to the holders of Rights by the Board; provided, however,
     that if at the time of such determination there shall be an Acquiring
     Person, the Fair Market Value of such property on such date shall be
     determined by a nationally recognized investment banking firm selected by
     the Board, which determination shall be described in a statement filed with
     the Rights Agent and shall be binding on the Company, the Rights Agent and
     the holders of the Rights.

         (e)   No adjustment in the Exercise Price shall be required unless such
adjustment would require an increase or decrease of at least 1% in the Exercise
Price then in effect; provided, however, that any adjustments which by reason of
this subsection (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 whole cent, to the nearest one
ten-thousandth of a share of Common Stock or other capital stock of any class
(other than Preferred Shares) or to the nearest one one-millionth of a Preferred
Share, as the case may be.  Notwithstanding the first sentence of this
subsection (e), any adjustment required by this Section 11 shall be made no
later than the earliest of (i) three years after the date of the 


                                     17


<PAGE>   21


occurrence requiring such adjustment, (ii) the Redemption Date and (iii) the
Final Expiration Date.

         (f)  If as a result of an adjustment required by any Triggering Event
the holder of any Rights thereafter exercised shall become entitled to receive
any shares of capital stock of any class of the Company (other than Preferred
Shares), the number of such other shares so receivable upon exercise of any
Rights shall be subject to adjustment from time to time in a manner and on terms
as nearly equivalent as reasonably possible to the provisions with respect to
the Preferred Shares contained in this Section 11, and the provisions of
Sections 7, 9, 10, 13 and 14 with respect to the Preferred Shares shall apply on
like terms to any such other shares.

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

         (h)  Unless the Company shall have exercised the option provided in
subsection (i) of this Section 11, upon each adjustment of the Exercise Price as
a result of the calculations required by subsection (b) or (c) of this Section
11, each Right outstanding immediately prior to the making of such Exercise
Price adjustment shall thereafter evidence the right to purchase, at the
adjusted Exercise Price, the number of one one-hundredths of a Preferred Share
(calculated to the nearest one one-millionth) determined by (i) multiplying the
number of one one-hundredths of a Preferred Share purchasable upon exercise of
such Right immediately prior to such adjustment by the Exercise Price in effect
immediately prior to such adjustment and (ii) dividing the product so obtained
by the Exercise Price in effect immediately after such adjustment.

         (i)  The Company may elect, on or after the date on which any
adjustment of the Exercise Price is required to be made hereunder, to adjust the
number of Rights outstanding in substitution for making an adjustment in the
number of one one-hundredths of a Preferred Share purchasable upon exercise of
each Right.  Each Right outstanding after such an adjustment in the number of
Rights shall be exercisable for the same number of one one-hundredths of a
Preferred Share as such Right was exercisable for immediately prior to such
adjustment; but each Right held of record prior to such adjustment shall become
the number of Rights (calculated to the nearest one ten-thousandth) determined
by dividing the Exercise Price in effect immediately prior to the occurrence
requiring the adjustment of the Exercise Price by the Exercise Price in effect
immediately after such adjustment of the Exercise Price.  The Company shall make
a prompt public announcement of its election to adjust the number of Rights
outstanding, indicating the record date for the adjustment and, if known at the
time of such announcement, the amount of the adjustment to be made.  Such record
date may be the date on which the Exercise Price is required to be adjusted or
any day thereafter, unless the Rights Certificates shall have been issued, in
which case such record date shall be at least 10 days after the date of such
public announcement.  If the Rights Certificates shall have been issued, upon
each adjustment of the number of Rights outstanding pursuant to this subsection
(i), the Company shall, as promptly as practicable, cause to be distributed to
each registered holder of the Rights Certificates on such record date Rights
Certificates evidencing, subject to Section 14, the additional Rights to which
such registered holder shall be entitled as a result of such adjustment; or, at
its option, the Company shall cause to be distributed to each such 


                                     18


<PAGE>   22


registered holder, in substitution and replacement for the Rights Certificates
held by such registered holder prior to the date of such adjustment, but only
upon surrender thereof (if so required by the Company), new Rights Certificates
evidencing all the Rights to which such registered holder shall be entitled
after such adjustment.  Rights Certificates so distributed shall be executed and
countersigned in the manner provided in Section 5 (and may designate, at the
option of the Company, the adjusted Exercise Price) and shall be registered in
the names of the registered holders of the Rights Certificates on the record
date specified in the aforesaid public announcement.

         (j)  Irrespective of any adjustment or change in the Exercise Price or
the number of one one-hundredths of a Preferred Share issuable upon exercise of
the Rights, the Rights Certificates theretofore and thereafter issued may
continue to designate the Exercise Price and the number of one one-hundredths of
a Preferred Share which were designated in the Rights Certificates originally
issued hereunder.

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

         (l)  In any case in which this Section 11 shall require an adjustment
of the Exercise Price effective as of the record date for a particular event,
the Company may elect to defer until the occurrence of such event the issuing to
the holder of any Rights exercised after such record date of the Preferred
Shares (and/or the other shares of capital stock, securities or other property
of the Company, if any) issuable upon such exercise in excess of the Preferred
Shares (and/or the other shares of capital stock, securities or other property
of the Company, if any) issuable upon such exercise on the basis of the Exercise
Price in effect immediately 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 excess upon the
occurrence of such event.

         (m)  Anything in this Section 11 to the contrary notwithstanding, the
Board shall be entitled to make reductions in the Exercise Price, in addition to
the adjustments expressly required by this Section 11, as and to the extent that
the Board, in its sole discretion, shall determine to be advisable in order that
any dividend on the Preferred Shares payable in Preferred Shares, any
subdivision, combination or consolidation of the Preferred Shares (by
reclassification or otherwise than by payment of dividends in Preferred Shares)
into a greater or lesser number of Preferred Shares, any issuance of Preferred
Shares solely for cash at less than the Fair Market Value thereof, any issuance
solely for cash of Preferred Shares or securities which by their terms are
convertible into or exchangeable for Preferred Shares or any issuance of
options, warrants, rights, securities, evidences of indebtedness or other
property subject to subsection (b) or (c) of this Section 11, hereafter made by
the Company to the holders of the Preferred Shares, shall not be taxable to such
holders.

         (n)  After the Distribution Date, the Company shall not consolidate or
merge with any other Person (other than a wholly-owned Subsidiary of the Company
in a transaction not prohibited by Section 11(o)), or sell or otherwise transfer
(or permit one or more of its Subsidiaries to sell or otherwise transfer), in
one or a series of related transactions, assets or 



                                     19


<PAGE>   23


earning power aggregating 50% or more of the assets or earning power of the
Company and its Subsidiaries (taken as a whole) to any other Person or Persons
(other than the Company or one or more of its wholly-owned Subsidiaries in one
or more transactions, each of which is not prohibited by Section 11(o)), if (i)
at the time of or immediately after the consummation of such transaction there
are any options, warrants, rights, conversion or exchange privileges or
securities outstanding or any written or oral agreements, arrangements or
understandings (including provisions contained in the Company's Certificate of
Incorporation or By-laws) in effect which, as a result of the consummation of
such transaction, would eliminate or substantially diminish the benefits
intended to be afforded by the Rights, or (ii) prior to, at the time of or
immediately after the consummation of such transaction the stockholders of the
Person who constitutes, or would constitute, the Principal Party for the purpose
of subsection (a) of this Section 13 shall have received a distribution of
Rights previously owned by such Person or any of its Affiliates or Associates.

         (o)  Except as permitted by Sections 23 and 27, the Company covenants
and agrees that, after the Distribution Date, it will not take, or permit any of
its Subsidiaries to take, any action if at the time such action would be taken
it is reasonably foreseeable that such action would eliminate or substantially
diminish the benefits intended to be afforded by the Rights.

         (p)  In the event that the Company shall at any time after the date of
this Agreement and prior to the Distribution Date (i) declare a dividend on its
outstanding shares of Common Stock payable in shares of Common Stock or (ii)
effect a subdivision, combination or consolidation of its outstanding shares of
Common Stock (by reclassification or otherwise than by payment of dividends in
shares of Common Stock) into a greater or lesser number of shares of Common
Stock, then, in each such case: (i) the number of one one-hundredths of a
Preferred Share purchasable after such event upon proper exercise of each Right
shall be determined by multiplying the number of one one-hundredths of a
Preferred Share so purchasable immediately prior to such event by a fraction,
the numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event; and (ii)
each share of Common Stock outstanding immediately after such event shall have
issued with respect to it the same number of Rights which each share of Common
Stock outstanding immediately prior to such event had issued with respect to it.
The adjustment required by this subsection (p) shall be made successively
whenever such a dividend is declared or such a subdivision, combination or
consolidation is effected.

         SECTION 12. CERTIFICATE OF ADJUSTED EXERCISE PRICE OR NUMBER OF SHARES.
Whenever any adjustment shall be required by Section 11, 13 or 23(g), the
Company shall promptly (i) prepare a certificate setting forth such adjustment
and a brief statement of the facts requiring such adjustment, (ii) file with the
Rights Agent and with each transfer agent for the Preferred Shares or the Common
Stock of the Company a copy of such certificate and (iii) mail a brief summary
thereof to each registered holder of the Rights in accordance with Section 26.
The Rights Agent shall be fully protected in relying on any such certificate and
on any adjustment described therein and shall not be obligated or responsible
for calculating any adjustment, nor shall it be deemed to have knowledge of any
such adjustment unless and until it shall have received such certificate.

         SECTION 13. CONSOLIDATION, MERGER OR SALE OR TRANSFER OF ASSETS OR
EARNING POWER.  (a)  In the event that, on or after the occurrence of any
Section 11(a)(ii) Event, 


                                     20


<PAGE>   24


directly or indirectly:  (i) the Company shall consolidate with, or merge with
and into, any Interested Stockholder or, if in such consolidation or merger all
holders of the Common Stock of the Company are not treated the same, any other
Person (other than a wholly-owned Subsidiary of the Company in a transaction not
prohibited by Section 11(o)), so that the Company shall not be the continuing or
surviving corporation, (ii) any Interested Stockholder or, if in such merger all
holders of the Common Stock of the Company are not treated the same, any other
Person (other than a wholly-owned Subsidiary of the Company in a transaction not
prohibited by Section 11(o)) shall merge with and into the Company, so that the
Company shall be the continuing or surviving corporation, and in connection with
such merger either (A) all or part of the outstanding shares of Common Stock of
the Company shall be converted or changed into or exchanged for capital stock or
other securities of any other Person (or the Company), cash and/or other
property or (B) such shares of Common Stock shall remain outstanding,
unconverted and unchanged, or (iii) the Company shall sell or otherwise transfer
(or one or more of its Subsidiaries shall sell or otherwise transfer), in one or
a series of related transactions, assets or earning power aggregating 50% or
more of the assets or earning power of the Company and its Subsidiaries (taken
as a whole) to any Interested Stockholder or, if in such transaction or
transactions the holders of the Common Stock of the Company are not treated the
same, any other Person or Persons (other than the Company or one or more of its
wholly-owned Subsidiaries in one or more transactions, each of which is not
prohibited by Section 11(o)), then, in each such case, proper provision shall be
made so that (w) the registered holder of each Right, except as otherwise
provided in Section 7(d), shall thereafter have the right to receive, upon
exercise thereof and payment of an amount equal to the product determined by
multiplying the then current Exercise Price by the number of one one-hundredths
of a Preferred Share for which such Right is then exercisable, in accordance
with this Agreement, in lieu of Preferred Shares, the number of freely tradable
shares (which shall be duly authorized, validly issued, fully paid and
non-assessable) of Common Stock of the Principal Party or, in the case of a
merger described in clause (ii) of this sentence in which the Common Stock of
the Company shall remain outstanding, unconverted and unchanged, of the Company,
free and clear of all rights of call or first refusal, liens, encumbrances or
other adverse claims, determined by dividing such product by 50% of the Fair
Market Value (determined as provided in Section 11(d)) of the shares of Common
Stock of such Principal Party (or, if appropriate, the Company) on the date of
consummation of such Section 13 Event; (x) such Principal Party shall thereafter
be liable for, and shall assume, by reason of the consummation of such Section
13 Event, all the obligations and duties of the Company under this Agreement;
(y) the term "Company" shall thereafter be deemed to refer to such Principal
Party, it being specifically intended that the provisions of Section 11 shall
apply to such Principal Party; and (z) such Principal Party shall take such
steps (including, but not limited to, the reservation of a sufficient number of
its shares of Common Stock to permit exercise of all outstanding Rights in
accordance with this subsection (a) and the distribution of cash, debt
securities, shares and other property in accordance with Section 11(a)(iv)) in
connection with the consummation of such Section 13 Event as may be necessary to
assure that the provisions hereof shall thereafter be applicable, as nearly as
reasonably possible, in relation to the shares of Common Stock thereafter
deliverable upon exercise of the Rights.

         (b)  The Company shall not consummate any Section 13 Event unless prior
thereto (i) 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 (ii) the Company, the Principal Party and each other Person who may become
the Principal Party as a result of the consummation of such 


                                     21


<PAGE>   25


Section 13 Event shall have executed and delivered to the Rights Agent a
supplemental agreement providing (x) for the implementation of all the terms and
conditions set forth in this Section 13 and (y) that, as soon as practicable
after the date of such Section 13 Event, the Principal Party, at its own
expense, shall:

         (A)  prepare and file a registration statement on an appropriate form
     under the Securities Act with respect to the Rights and the securities
     purchasable upon exercise thereof, and use its best efforts to cause such
     registration statement to become effective as soon as practicable after
     such filing and to remain effective (with a prospectus which at all times
     meets the requirements of the Securities Act) until the earliest of the
     date as of which the Rights are no longer exercisable for such securities,
     the Redemption Date and the Final Expiration Date;

         (B)  use its best efforts to qualify or register the Rights and the
     securities purchasable upon exercise thereof under the securities or "blue
     sky" laws of such jurisdictions as may be necessary or appropriate in
     connection with the exercisability of the Rights;

         (C)  use its best efforts to list (or continue the listing of) the
     Rights and the securities purchasable upon exercise thereof on a national
     securities exchange or to meet the eligibility requirements for quotation
     on NASDAQ; and

         (D)  deliver to the registered holders of the Rights historical
     financial statements for the Principal Party and each of its Affiliates
     complying in all material respects with the requirements for registration
     of securities on Form 10 under the Exchange Act.

         (c)  Notwithstanding anything in this Agreement to the contrary,
Section 13 shall not apply to a transaction described in clause (i) or (ii) of
subsection (a) thereof if (i) such transaction is consummated with a Person or
Persons who acquired their shares of Common Stock of the Company pursuant to a
Permitted Offer, (ii) the price per share of Common Stock of the Company
provided in such transaction shall not be less than the price per share of
Common Stock of the Company paid to all holders whose shares were purchased
pursuant to such Permitted Offer and (iii) the form of consideration being
offered to the remaining holders of the Common Stock of the Company pursuant to
such transaction is the same as the form of consideration paid pursuant to such
Permitted Offer.  Upon consummation of any transaction authorized by this
subsection (c), all Rights shall expire.

         (d)  "Principal Party" shall mean:  in the case of any transaction
described in clause (i) or (ii) of subsection (a) of this Section 13, the Person
which is the issuer of the securities into which shares of Common Stock of the
Company are being converted or changed in such transaction or, if there shall be
more than one such issuer, the issuer having shares of Common Stock with the
greatest aggregate market value; or if no securities are being issued in such
transaction for shares of Common Stock of the Company, the Person which is the
other party to such transaction or, if there shall be more than one such Person,
the Person having shares of Common Stock with the greatest aggregate market
value; and in the case of any transaction described in clause (iii) of such
subsection (a), the Person which is the party receiving the greatest portion of
the assets or earning power sold or otherwise transferred pursuant to such
transaction or transactions; provided, however, that in any such case (i) if the
shares of Common Stock of such Person shall not at the time of the consummation
of such 


                                     22


<PAGE>   26


transaction have been continuously registered under Section 12 of the Exchange
Act during the immediately preceding 12-month period, and such Person shall be a
direct or indirect Subsidiary or Affiliate of another Person the shares of
Common Stock of which shall have been so registered, "Principal Party" shall
mean such other Person; and (ii) if such Person shall be a direct or indirect
Subsidiary or Affiliate of more than one other Person, the shares of Common
Stock of two or more of which shall have been so registered, "Principal Party"
shall mean whichever of such other Persons  shall have Common Stock with the
greatest aggregate market value; and (iii) if such Person shall be owned,
directly or indirectly, by a joint venture formed by two or more Persons which
are not owned, directly or indirectly, by the same Person, the rules set forth
in clauses (i) and (ii) of this proviso shall apply to each chain of ownership
of any joint venturer as though such joint venture were a "Subsidiary" of all of
such joint venturers, and the Principal Party in each such chain shall bear the
obligations and duties set forth in this Section 13 in the same proportion as
their direct or indirect ownership interest in such Person bears to the total of
such ownership interests.

         (e)  If, in the case of any transaction described in clause (iii) of
subsection (a) of this Section 13, the Person or Persons to whom assets or
earning power are sold or otherwise transferred are individuals, then, in lieu
of any other payment or distribution required by this Section 13, and the
Company shall require as a condition to such transaction that, such Person or
Persons shall pay to each holder of a Rights Certificate, upon its surrender to
the Rights Agent and in exchange therefor (without requiring any payment by such
holder), cash in the amount determined by multiplying the then current Exercise
Price by the number of one one-hundredths of a Preferred Share for which a Right
is then exercisable.

         (f)  In no event shall the Rights Agent have any obligations or duties
in respect of any Section 13 Event, except as expressly set forth in this
Agreement.  The Rights Agent may rely, and shall be fully protected in relying
upon, a certificate of the Company stating that the provisions of this Section
13 have been fulfilled.  The prior written consent of the Rights Agent shall be
required in connection with any supplemental agreement which alters or impairs
the rights, obligations, duties or immunities of the Rights Agent hereunder.

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

         SECTION 14. FRACTIONAL RIGHTS AND FRACTIONAL SHARES.  (a)  The Company
shall not be required to issue fractional Rights or to distribute Rights
Certificates which evidence fractional Rights.  If the Company shall determine
not to issue fractional Rights, the Company shall pay, in lieu of issuing
fractional Rights, to the registered holders of the Rights with respect to which
fractional Rights would otherwise be issuable an amount in cash equal to the
same fraction of the Fair Market Value (determined as provided in Section 11(d)
for the Trading Day immediately prior to the date on which such fractional
Rights would otherwise have been issued) of one Right.

         (b)  The Company shall not be required to issue fractional Preferred
Shares (other than fractions which are multiples of one one-hundredth of a
Preferred Share) upon exercise of the Rights or to distribute stock certificates
which evidence fractional Preferred 



                                     23


<PAGE>   27


Shares (other than fractions which are multiples of one one-hundredth of a
Preferred Share).  If the Company shall determine not to issue fractional
Preferred Shares that are not multiples of one one-hundredth of a Preferred
Share, the Company shall pay to the registered holders of the Rights
Certificates at the time Rights represented thereby are exercised, in lieu of
such fractional Preferred Shares, an amount in cash equal to the same fraction
of the Fair Market Value (determined as provided in Section 11(d) for the
Trading Day immediately prior to the date of such exercise) of one one-hundredth
of a Preferred Share.

         (c)  Following the occurrence of a Triggering Event, the Company, at
its option, 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.

         (d)  Each holder of a Right, by accepting the same, expressly waives
such holder's right to receive or exercise any fractional Right or to receive
any fractional Preferred Share upon the exercise of such Right (except as
provided in this Section 14).

         SECTION 15. RIGHTS OF ACTION.  All rights of action in respect of this
Agreement, other than rights of action which the Rights Agent may have under
Sections 18 and 20, are vested in the registered holders of the Rights
Certificates (or, prior to the Distribution Date, the registered holders of the
Common Stock of the Company); and the registered holder of any Rights
Certificate (or, prior to the Distribution Date, of any stock certificate for
shares of such 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
any other stock certificate for shares of Common Stock), may, on such registered
holder's own behalf and for such registered holder's own benefit, enforce, and
may institute and maintain any suit, action or proceeding against the Company to
enforce, or otherwise act in respect of, such registered holder's right to
exercise the Rights evidenced by such Rights Certificate (or, prior to the
Distribution Date, such stock certificate) in the manner provided in such Rights
Certificate and in this Agreement.  Without limiting the generality of the
foregoing or any remedies available to the holders of the Rights, it is
specifically acknowledged that the registered holders of the Rights would not
have an adequate remedy at law for any breach of this Agreement and will be
entitled to specific performance of the obligations and duties under, and
injunctive relief against any actual or threatened violations of the obligations
and duties of any Person subject to, this Agreement.

         SECTION 16. AGREEMENTS OF HOLDERS OF RIGHTS.  Each 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:

         (i)   prior to the Distribution Date, the Rights shall be
     transferable only simultaneously and together with the transfer of
     shares of Common Stock of the Company;



                                     24


<PAGE>   28


         (ii)  after the Distribution Date, the Rights Certificates
     shall be transferable on the registry books of the Rights Agent
     only if surrendered at the principal office of the Rights Agent,
     with the Form of Assignment and Certification of Status on the
     reverse side thereof duly executed, together with such signature
     guarantees and other documentation as the Rights Agent may
     reasonably request;

         (iii) subject to Sections 6 and 7(d), the Company and the
     Rights Agent may deem and treat the Person in whose name any Rights
     Certificate (or, prior to the Distribution Date, any stock
     certificate for Common Stock of the Company) is registered as the
     absolute owner thereof and of the Rights represented thereby
     (notwithstanding any notations of ownership or other writing on
     such Rights Certificate or 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 shall be affected by
     any notice to the contrary; and

         (iv)  neither the Company nor the Rights Agent shall have any
     liability to any holder of a Right or to any other Person because
     of its inability to perform any of its obligations or duties under
     this Agreement by reason of any applicable law, 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 rule, regulation or
     executive order promulgated or enacted by any such governmental
     authority prohibiting or otherwise restraining performance of any
     such obligation or duty; provided, however, that the Company shall
     use its best efforts to have any such injunction, order, decree or
     ruling lifted or otherwise overturned as soon as reasonably
     possible.

         SECTION 17. RIGHTS CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER.  No
holder, as such, of any Rights Certificate shall be entitled to vote, to receive
dividends or other distributions on or to exercise any preemptive rights with
respect to, or shall be deemed for any other purpose to be the holder of, the
Preferred Shares or other shares of capital stock of any class of the Company
which may at the time be issuable upon 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 other matter submitted to stockholders at any
meeting thereof, to give or withhold consent to any corporate action, to receive
notice of meetings or other actions affecting stockholders (except as provided
in Section 25) or to receive dividends, subscription rights or other
distributions, until the Rights represented by such Rights Certificate shall
have been exercised, in whole or in part, in accordance with the provisions
hereof.

         SECTION 18. CONCERNING THE RIGHTS AGENT.  (a) The Company covenants and
agrees to pay to the Rights Agent reasonable compensation for all services
rendered by it hereunder and, from time to time on the written request of the
Rights Agent, to reimburse it for all reasonable expenses and counsel fees
incurred in connection with the acceptance and administration of this Agreement
and the performance of its obligations and duties hereunder.  The Company also
covenants and agrees to indemnify the Rights Agent for, and to hold it harmless
against, any loss, liability or expense, incurred without negligence, bad faith
or willful 


                                     25


<PAGE>   29


misconduct on its part, for any action taken, suffered or omitted by it in
connection with the acceptance and administration of this Agreement and the
performance of its obligations and duties hereunder, including the costs and
expenses of defending against any claim of liability arising therefrom, directly
or indirectly.  The indemnity provided for herein shall survive the expiration
of the Rights, the termination of this Agreement, and the resignation or removal
of the Rights Agent.  The costs and expenses of enforcing this right of
indemnification shall also be paid by the Company.

         (b)  The Rights Agent may conclusively rely upon and shall be protected
and shall incur no liability for, or in respect of, any action taken, suffered
or omitted by it in connection with its administration of this Agreement in
reliance upon any Rights Certificate, stock certificate for Preferred Shares,
Common Stock or other shares of capital stock of the Company, instrument of
assignment or transfer, power of attorney, endorsement, affidavit, notice,
direction, consent, certificate, statement or other paper or document believed
by it to be genuine and to be executed and, where necessary, verified or
acknowledged by the proper Person or Persons.

         (c)  Notwithstanding anything in this Agreement to the contrary, in no
event shall the Rights Agent be liable for special, indirect or consequential
loss or damage of any kind whatsoever (including but not limited to lost
profits), even if the Rights Agent has been advised of the likelihood of such
loss or damage and regardless of the form of the action.

         SECTION 19. MERGER OR CONSOLIDATION OF THE RIGHTS AGENT.  (a) Any
corporation into which the Rights Agent or any successor Rights Agent may be
merged or with which it may be consolidated, or any corporation resulting from
any merger or consolidation to which the Rights Agent or any successor Rights
Agent shall be a party, or any corporation succeeding to the stockholder
services or corporate trust business of the Rights Agent or any successor Rights
Agent, shall be the successor to the Rights Agent under this Agreement without
the execution or filing of any paper or any further act on the part of any of
the parties hereto, provided that such corporation would be eligible for
appointment as successor Rights Agent under Section 21.  In case at the time any
successor Rights Agent shall succeed to the agency created by this Agreement any
of the Rights Certificates countersigned by its predecessor Rights Agent shall
not have been delivered, such successor Rights Agent may adopt the
countersignature of its predecessor Rights Agent and deliver the Rights
Certificates so countersigned; or in case at such time any of the Rights
Certificates shall not have been countersigned, such successor Rights Agent may
countersign such Rights Certificates either in the name of its predecessor
Rights Agent or in the name of such successor Rights Agent; and in all such
cases, such Rights Certificates shall have the full force and effect provided
therein 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 the Rights Certificates so countersigned; or in case at
such 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 and effect provided therein and in this Agreement.

         SECTION 20. DUTIES OF THE RIGHTS AGENT.  The Rights Agent undertakes
the obligations and duties imposed by this Agreement upon the following terms
and conditions, by all of which the Company and the holders of the Rights
Certificates (or, prior to the Distribution Date, the stock certificates for
Common Stock of the Company), by accepting the same, shall be bound, and no
implied obligations or duties shall be read into this Agreement against the
Rights Agent:

         (i)   before the Rights Agent acts or refrains from acting, the
     Rights Agent may consult with legal counsel (who may be legal
     counsel for the Company), and the written opinion of such legal
     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 opinion;

         (ii)  whenever in the performance of its duties under this
     Agreement the Rights Agent shall deem it necessary or desirable
     that any fact or matter be proved or established by the Company
     prior to taking, 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 executed by any one of 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 and complete
     authorization and protection to the Rights Agent as to any action
     taken, suffered or omitted by it in good faith in reliance upon
     such certificate;

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

         (iv)  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 (except its
     countersignature thereon) or be required to verify the same, but
     all such statements and recitals are and shall be deemed to have
     been made by the Company only;

         (v)   the Rights Agent shall not be responsible for the
     validity of this Agreement or the execution and delivery hereof
     (except for its due execution hereof) or for the validity or
     execution of any Rights Certificate (except for its
     countersignature thereon); nor shall the Rights Agent be
     responsible for any breach by the Company of any covenant or
     condition contained in this Agreement or in any Rights Certificate;
     nor shall the Rights Agent be responsible for any change in the
     exercisability of the Rights (including Rights becoming void
     pursuant to Section 7(d)), for any adjustment or change (or for the
     manner or method of determining same) in the terms of the Rights
     (including any adjustment or change in the Exercise Price or in the
     number or kind of shares, securities or other property issuable
     upon the exercise thereof) required by Section 11, 13, 23 or 24 or
     for ascertaining the existence of facts which would require any
     such change or adjustment (except with respect to the exercise of
     Rights evidenced by Rights Certificates after actual notice, in the
     manner provided in Section 12, that such change or adjustment is
     required); nor shall the Rights Agent by any act hereunder be
     deemed to have made any representation 



                                     27


<PAGE>   31


     or warranty as to the authorization or reservation of any Preferred
     Shares or shares of Common Stock to be issued pursuant to this
     Agreement or any Rights Certificate or as to whether any Preferred
     Shares or shares of Common Stock will, when issued, be validly
     authorized and issued and fully paid and nonassessable;

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

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

         (viii) the Rights Agent and any stockholder, director, officer
     or employee of the Rights Agent may buy, sell or deal in the Rights
     or in any other securities of the Company (including the Preferred
     Shares and its Common Stock) or become pecuniarily interested in
     any transaction in which the Company (or any of its Subsidiaries)
     may be interested, or contract with or lend money to the Company
     (or any of its Subsidiaries), and may otherwise act as fully and
     freely as though it were not the Rights Agent under this Agreement;
     and nothing herein shall preclude the Rights Agent from acting in
     any other capacity for the Company, any of its Subsidiaries or any
     other entity;

         (ix)   the Rights Agent may execute and exercise any of the
     rights or powers hereby vested in it or perform any of its
     obligations or duties hereunder either directly 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 attorney or agent or for any loss to the
     Company resulting from any 



                                     28


<PAGE>   32


     such act, default, neglect or misconduct, provided the Rights Agent
     exercised reasonable care in the selection and continued employment
     of such attorney or agent;

         (x)   if, with respect to any Rights Certificate surrendered to
     the Rights Agent for exercise or transfer, the Form of Certification
     of Status attached to the Form of Election to Purchase or the Form of
     Assignment, as the case may be, has either not been completed or
     indicates an affirmative response to Question 1 and/or 2 thereof, the
     Rights Agent shall not take any further action with respect to the
     requested exercise or transfer without first consulting with the
     Company;

         (xi)  no provision of this Agreement shall require the Rights
     Agent to expend or risk its own funds or otherwise incur any
     financial liability in the performance of any of its obligations or
     duties or in the exercise of its rights or powers hereunder 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; and

         (xii) the Rights Agent shall not be required to take notice or
     be deemed to have notice of any fact, event or determination
     (including, without limitation, any dates or events defined in this
     Agreement or the designation of any Person as an Acquiring Person,
     Affiliate or Associate) under this Agreement unless and until the
     Rights Agent shall be specifically notified in writing by the
     Company of such fact, event or determination.

         SECTION 21. RESIGNATION OR REMOVAL OF THE RIGHTS AGENT.  The Rights
Agent or any successor Rights Agent may resign and be discharged from its
obligations and duties under this Agreement upon 30 days' prior notice to the
Company and to each transfer agent for the Preferred Shares and for the Common
Stock of the Company, sent by registered or certified mail, postage prepaid,
and, at the expense of the Company, to each registered holder of the Rights
Certificates, sent by first-class mail, postage prepaid.  The Company may remove
the Rights Agent or any successor Rights Agent upon 30 days' prior notice to the
Rights Agent or successor Rights Agent, as the case may be, and to each transfer
agent for the Preferred Shares and for the Common Stock of the Company, sent by
registered or certified mail, postage prepaid, and to each registered holder of
the Rights Certificates, sent by first-class mail, postage prepaid.  If the
Rights Agent or any successor Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor
Rights Agent.  If the Company shall fail to make such appointment within 30 days
after giving notice of such removal or after receiving notice of such
resignation or incapacity, either from the resigning or incapacitated Rights
Agent or from the registered holder of any Rights Certificate (who shall, with
such notice, submit its Rights Certificate for inspection by the Company), then
the incumbent Rights Agent or the registered holder of any Rights Certificate
may apply to any court of competent jurisdiction for the appointment of a
successor Rights Agent.  Any successor Rights Agent, whether appointed by the
Company or by such a court, shall be either (a) a corporation organized and
doing business under the laws of the United States of America, the State of
Delaware, the State of New York or the State of Illinois (or of any other state
so long as such corporation is authorized to do business as a banking
institution in the State of Delaware, the State of New York or the State of
Illinois), be in good standing under the laws of the jurisdiction of its
incorporation, have an office in the State of Delaware, 



                                     29


<PAGE>   33


the State of New York or the State of Illinois, be authorized under such laws to
exercise corporate trust or stock transfer powers, be subject to supervision or
examination by federal or state authority and have at the time of its
appointment as Rights Agent a combined capital and surplus of at least
$50,000,000 or (b) an Affiliate of such a corporation.  After its appointment,
the successor Rights Agent shall be vested with the same rights, powers,
obligations, duties and immunities 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 for the Preferred Shares and
for the Common Stock of the Company, and mail notice thereof 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 any successor
Rights Agent or the appointment of any successor thereto.

         SECTION 22. ISSUANCE OF NEW RIGHTS CERTIFICATES.  Notwithstanding any
provision of this Agreement or of the Rights Certificates to the contrary, the
Company may, at its option, issue new Rights Certificates evidencing the Rights
in such form as may be approved by the Board to reflect any adjustment or change
in the Exercise Price or in the number or kind of shares, securities or other
property issuable upon exercise of the Rights in accordance with the provisions
of this Agreement; provided, however, that (i) no such Rights Certificates shall
be issued if, and to the extent that, the Company shall be advised by counsel
that such issuance could create a significant risk of material adverse tax
consequences to the Company or to the Persons to whom such Rights Certificates
would be issued and (ii) no such Rights Certificates 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.  (a)  The Board may, at its option, at any time
prior to the earliest of (i) the Close of Business on the 10th Business Day
after the Share Acquisition Date (or, if the Share Acquisition Date shall have
occurred prior to the Record Date, the Close of Business on the 10th Business
Day after the Record Date), or (ii) the Final Expiration Date, redeem all, but
not less than all, of the then outstanding Rights at a redemption price of $.001
per Right, adjusted as provided in subsection (g) of this Section 23 (such
redemption price being hereinafter called the "REDEMPTION PRICE"); provided,
however, that if the Board shall authorize the redemption of the Rights in the
circumstances set forth in either clause (A) or (B) below, there must be
Continuing Directors then in office and such authorization shall require the
concurrence of at least a majority of such Continuing Directors: (A) such
authorization shall occur on or after the date a Person becomes an Acquiring
Person or (B) such authorization shall occur on or after the date of a change
(resulting from a solicitation of either proxies or one or more written
stockholder consents) in a majority of the directors in office at the
commencement of such solicitation if any Person who shall be a participant in
such solicitation has stated (or, if upon the commencement of such solicitation,
at least a majority of the Continuing Directors shall have determined in good
faith) that such Person (or any of its Affiliates or Associates) intends to
take, or may consider taking, any action which would result in such Person
becoming an Acquiring Person or which would cause the occurrence of a Triggering
Event.




                                     30


<PAGE>   34


         (b)  In addition to the right of redemption reserved in the first
sentence of subsection (a) of this Section 23, if there shall be Continuing
Directors then in office, the Board may redeem, with the concurrence of at least
a majority of the Continuing Directors, all, but not less than all, of the then
outstanding Rights at the Redemption Price after the Share Acquisition Date, but
prior to the occurrence of any Section 13 Event, if either (i) the Person who is
an Acquiring Person shall have transferred or otherwise disposed of (either
alone or together with its Affiliates and Associates) such number of shares of
Common Stock of the Company, in one or a series of related transactions not
directly or indirectly involving the Company or any of its Subsidiaries or the
occurrence of any Section 13 Event, as shall result in such Person thereafter
being a Beneficial Owner of less than 15% of the then outstanding shares of
Common Stock of the Company, and after such transfer or other disposition there
is no other Acquiring Person, or (ii) in connection with any Section 13 Event
which shall not involve an Interested Stockholder and in which all holders of
the Common Stock of the Company are treated the same.

         (c)  Notwithstanding any other provision of this Agreement, the Rights
shall not be exercisable after the first occurrence of any Section 11(a)(ii)
Event until such time as the Company's right of redemption under this Section 23
shall have expired.

         (d)  In considering whether to redeem the Rights, the Board and the
Continuing Directors may consider the best long-term and short-term interests of
the Company and its stockholders, including, without limitation, the effects of
the redemption of the Rights upon employees, creditors, suppliers and customers
of the Company or of its Subsidiaries and upon the communities in which offices
or other establishments of the Company and such Subsidiaries are located and all
other pertinent factors.  The redemption of the Rights by the Board may be made
effective at such time, on such basis and with such conditions as the Board, in
its sole discretion, may establish.

         (e)  Immediately after action by the Board directing the redemption of
the Rights pursuant to subsection (a) or (b) of this Section 23, and without any
further action and without any notice, the right to exercise the Rights shall
terminate, and thereafter each registered holder of the Rights shall only be
entitled to receive the Redemption Price therefor. The Company shall give prompt
written notice to the Rights Agent and prompt public notice to the holders of
the Rights of any such redemption; provided, however, that the failure to give,
or any defect in, any such notice shall not affect the validity of such
redemption.  Within 10 days after action by the Board directing the redemption
of the Rights, the Company shall mail (or cause the Rights Agent to mail) a
notice of redemption to each registered holder of the then outstanding Rights,
at its last address appearing on 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 of the Company.  Any notice which is mailed in the manner
provided in this subsection (e) shall be deemed given, whether or not received
by the registered holder to whom sent.  Each notice of redemption shall state
the method by which payment of the Redemption Price is to be made.  Neither the
Company nor any of its Affiliates or Associates may at any time redeem, acquire
or purchase for value any Rights other than in the manner set forth in this
Section 23 and Section 24 or in connection with any purchase of outstanding
shares of its Common Stock prior to the Distribution Date.



                                     31


<PAGE>   35


         (f)  The Company may, at its option, pay the Redemption Price in cash,
shares of Common Stock based on its Fair Market Value (determined as provided in
Section 11(d)) as of the date of redemption or any other form of consideration
deemed appropriate by the Board.

         (g)  In the event that the Company shall at any time after the date of
this Agreement (i) declare a dividend on its outstanding shares of Common Stock
payable in shares of Common Stock or (ii) effect a subdivision, combination or
consolidation of its outstanding shares of Common Stock (by reclassification or
otherwise than by payment of dividends in shares of Common Stock) into a greater
or lesser number of shares of Common Stock, then, in each such case, the
Redemption Price after such event shall equal the Redemption Price in effect
immediately prior to such event multiplied by a fraction, the numerator of which
shall be the number of shares of Common Stock outstanding immediately prior to
such event and the denominator of which shall be the number of shares of Common
Stock outstanding immediately after such event; provided, however, that such
adjustment shall be made only if the amount of the Redemption Price would be
reduced or increased by at least $0.001 per Right.

         SECTION 24. EXCHANGE.  (a)  The Board may, at its option, at any time
on or after the occurrence of any Section 11(a)(ii) Event, exchange all or any
part of the then outstanding and exercisable Rights (which shall not include any
Rights which have become void pursuant to Section 7(d)) for shares of Common
Stock of the Company at an exchange rate of one share of Common Stock per Right,
appropriately adjusted to reflect any event specified in clauses (A) through
(D), inclusive, of the first sentence of Section 11(a)(i) or in Section 11(n)
occurring after the date hereof (such exchange rate being hereinafter called the
"EXCHANGE RATE"); provided, however, that the Board shall not be authorized to
effect such an exchange at any time after any Person (other than an Exempt
Person), together with the Affiliates and Associates of such Person, shall have
become the Beneficial Owner of 50% or more of the then outstanding shares of
Common Stock of the Company.

         (b)  Immediately after action by the Board directing the exchange of
any Rights pursuant to subsection (a) of this Section 24, and without any
further action and without any notice, the right to exercise such Rights shall
terminate, and thereafter each registered holder of such Rights shall only be
entitled to receive the number of shares of Common Stock of the Company which
shall equal the number of such Rights held by such registered holder multiplied
by the Exchange Rate then in effect.  The Company shall give prompt written
notice to the Rights Agent and prompt public notice to the holders of the Rights
of any such exchange; provided, however, that the failure to give, or any defect
in, any such notice shall not affect the validity of such exchange. Within 10
days after action by the Board directing the exchange of any Rights, the Company
shall mail (or cause the Rights Agent to mail) a notice of exchange to each
registered holder of such Rights, at its last address appearing on 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 of the Company.  Any notice
which is mailed in the manner provided in this subsection (b) shall be deemed
given, whether or not received by the registered holder to whom sent. Each
notice of exchange shall state the method by which the exchange of shares of
Common Stock for Rights will be effected and, in the event of any partial
exchange, the number of Rights which will be exchanged.  Any partial exchange
shall be effected pro rata among the registered holders of the Rights based upon
the number of Rights held (excluding Rights which shall have become void
pursuant to Section 7(d)); and, in such case, a new Rights Certificate
evidencing the Rights not being exchanged shall be prepared and executed by the




                                     32


<PAGE>   36


Company and countersigned and delivered by the Rights Agent to the registered
holder of such Rights.

         (c)  In any exchange pursuant to this Section 24, the Company, at its
option, may substitute Preferred Shares (or Equivalent Preferred Shares) for
shares of Common Stock in effecting an exchange for Rights, at the initial rate
of one one-hundredth of a Preferred Share (or Equivalent Preferred Share) for
each share of Common Stock, appropriately adjusted to reflect any adjustments in
the voting rights of the Preferred Shares pursuant to the Certificate of
Designations attached hereto as Exhibit A, so that the fractional Preferred
Share delivered in lieu of each share of Common Stock shall have the same voting
rights as one share of Common Stock.

         (d)  In the event that there shall not be sufficient authorized and
unissued or treasury shares of Common Stock or Preferred Shares (or Equivalent
Preferred Shares) to permit the exchange of Rights directed by the Board, the
Company shall take all necessary action to authorize and reserve for issuance
such number of additional shares of Common Stock or Preferred Shares (or
Equivalent Preferred Shares) as may be required for issuance upon such exchange
and, if necessary, shall use its best efforts to obtain stockholder approval
thereof.

         (e)  The Company shall not be required to issue fractional shares of
Common Stock in exchange for Rights or to distribute stock certificates which
evidence fractional shares of Common Stock.  If the Company shall determine not
to issue fractional shares of Common Stock, the Company shall pay to the
registered holders of the Rights with respect to which such fractional shares
would otherwise be issuable an amount in cash equal to the same fraction of the
Fair Market Value (determined as provided in Section 11(d) for the Trading Day
immediately prior to the date of such exchange) of one share of Common Stock.

         SECTION 25. NOTICE TO HOLDERS OF RIGHTS CERTIFICATES OF CERTAIN EVENTS.
(a)  In the event that at any time after the Distribution Date, the Company
shall propose:  (i) to pay any dividend payable in shares of capital stock of
any class of the Company to the holders of Preferred Shares or to make any other
cash distribution to the holders of Preferred Shares (other than a regular
quarterly cash dividend); (ii) to effect any reclassification of the Preferred
Shares (other than a reclassification involving only the subdivision of the
outstanding Preferred Shares); (iii) to make any distribution to the holders of
Preferred Shares described in subsection (b) or (c) of Section 11; (iv) to
effect any Section 13 Event; (v) to pay any dividend on its shares of Common
Stock payable in shares of Common Stock or to effect a subdivision, combination
or consolidation of its outstanding shares of Common Stock (by reclassification
or otherwise than by payment of dividends in shares of Common Stock); or (vi) to
effect the liquidation, dissolution or winding up of the Company; then, in each
such case, the Company shall give to the Rights Agent and each registered holder
of the Rights, in the manner provided in Section 26, written notice of such
proposed action, which shall specify the record date for such stock dividend or
distribution or the date on which such reclassification, Section 13 Event,
liquidation, dissolution or winding up is expected to occur (and the date for
participation therein by the holders of the Common Stock and/or Preferred Shares
if any such date is to be fixed).  Such notice shall be given, in the case of
any action described in clause (i) or (iii) of the preceding sentence, at least
10 days prior to the record date and, in the case of any other such action, at
least 10 days prior to the date of taking of such proposed action or the date
for participation therein by the holders of Preferred Shares, whichever shall be
the earlier.


                                     33


<PAGE>   37


         (b)  In case any Section 11(a)(ii) Event shall occur, the Company
shall, as soon as practicable thereafter, give to the Rights Agent and each
registered holder of the Rights, in the manner provided in Section 26, written
notice of the occurrence thereof, which notice shall describe such occurrence
and its consequences in reasonable detail.

         SECTION 26. OTHER NOTICES.  Except as otherwise provided herein,
notices or demands authorized by this Agreement to be given or made by the
Rights Agent or by the registered holder of any Rights, Rights Certificate or
stock certificate for shares of Common Stock of the Company to or on the Company

Agreement to be given or made by the Company or by the registered holder of any

Except as otherwise provided herein, notices or demands authorized by this
Agreement to be given or made by the Company or the Rights Agent to the
registered holder of any Rights, Rights Certificate or stock certificate for

sent by first-class mail, postage prepaid, addressed to such holder at its last
address appearing on 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 of the Company.

         SECTION 27. SUPPLEMENTS AND AMENDMENTS.  Prior to the Distribution
Date, the Company may (and the Rights Agent, if so directed in writing by the
Company, shall) supplement or amend any term, provision or condition of this
Agreement, without the approval of the registered holders of the stock
certificates representing the Common Stock and the Rights.  From and after the
Distribution Date, but subject to the penultimate sentence of this Section 27,
the Company may (and the Rights Agent, if so directed in writing by the Company
shall) supplement or amend this Agreement, without the approval of the
registered holders of the Rights (however represented), in order: (i) to cure
any ambiguity, (ii) to correct or supplement any term, provision or condition of
this Agreement which may be defective or inconsistent with any other term,
provision or condition hereof, (iii) to shorten or lengthen any 


                                     34


<PAGE>   38



time period specified herein (except that after the first occurrence of an event
described in either clause (A) or (B) of the proviso in the first sentence of
Section 23(a), there must be Continuing Directors then in office and any such
shortening or lengthening shall require the concurrence of at least a majority
of such Continuing Directors) or (iv) to change or supplement one or more of the
terms, provisions or conditions hereof in any manner which the Company may deem
necessary or desirable and which shall not adversely affect, as determined by
the Board (with the concurrence of at least a majority of the Continuing
Directors), the interests of the holders (other than any Restricted Person or
the transferees therefrom specified in Section 7(d)) of the Rights (however
represented); provided, however, that this Agreement may not be supplemented or
amended pursuant to clause (iii) of this sentence (A) to lengthen any time
period (except as permitted by Section 3(a)(ii)) unless (I) approved by at least
a majority of the Continuing Directors and (II) such lengthening is for the
purpose of protecting, enhancing or clarifying the rights of, and/or the
benefits to, the holders (other than any Restricted Person or the transferees
therefrom specified in Section 7(d)) of the Rights or (B) to lengthen any time
period relating to when the Rights may be redeemed if at such time the Rights
are not then redeemable.  Upon the delivery of a certificate from an appropriate
officer of the Company stating that the proposed supplement or amendment is in
compliance with the terms of this Section 27, the Rights Agent shall execute
such supplement or amendment; provided, however, that the Rights Agent shall not
be required to execute any supplement or amendment which affects any of the
Rights Agent's rights, powers, obligations, duties or immunities under this
Agreement.  On and after the Distribution Date, no supplement or amendment shall
be made which changes the Exercise Price, the number of one one-hundredths of a
Preferred Share for which a Right is exercisable, the Redemption Price or the
Final Expiration Date.  Prior to the Distribution Date, the interests of the
holders of the Rights shall be deemed coincident with the interests of the
holders of the Common Stock of the Company.

         SECTION 28. SUCCESSORS.  All of the terms, provisions and conditions 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.

         SECTION 29. CERTAIN DETERMINATIONS AND ACTIONS BY THE BOARD.  For all
purposes of this Agreement, any calculation of the number of shares of Common
Stock outstanding at any particular time, including the determination of the
percentage of such outstanding shares of which any Person is the Beneficial
Owner, shall be made in accordance with the last sentence of Rule
13d-3(d)(1)(i), as in effect on the date hereof, under the Exchange Act.  The
Board (or, as and when set forth herein, the Continuing Directors) shall have
the exclusive power and authority to interpret 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 make all determinations
deemed necessary or advisable for such administration, including, without
limitation, a determination to redeem or not to redeem the Rights, to exchange
or not to exchange the Rights, or to supplement or amend this Agreement.  All
such calculations, determinations, interpretations and exercises (including, for
purposes of clause (ii) below, all omissions with respect to the foregoing)
which are done or made by the Board (or the Continuing Directors) in good faith
shall (i) be final, conclusive and binding on the Company, the Rights Agent, the
holders of the Rights and all other Persons and (ii) not subject any director
(including any Continuing Director) to any liability to the holders of the
Rights or to any other Person.

         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, the registered holders of the stock certificates for the
Common Stock of the Company) 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, the registered holders of the
stock certificates for the Common Stock of the Company).

         SECTION 31. SEVERABILITY.  If any term, provision or condition of this
Agreement shall be held by a court of competent jurisdiction or other lawful
authority to be invalid, void or unenforceable, the remaining terms, provisions,
and conditions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated; provided, however, that if any
such term, provision or condition is held by such court or authority to be
invalid, void or unenforceable and the Board (with the concurrence of at least a
majority of the Continuing Directors then in office) shall determine in good
faith that severing the same from this Agreement would adversely affect the
purposes or effect of this Agreement, the right of redemption set forth in
Section 23 shall be reinstated and shall not expire until the Close of Business
on the 10th day following the date of such determination by the Board.

         SECTION 32. GOVERNING LAW.  This Agreement and each Rights Certificate
issued hereunder shall be deemed to be a contract made under the laws of the
State of Delaware and for all purposes shall be governed by and construed in
accordance with the laws of such State applicable to contracts made and to be
performed entirely within such State, except as to the rights and obligations of
the Rights Agent, which shall be governed by and construed in accordance with
the laws of the State of Illinois.

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

         SECTION 34. DESCRIPTIVE HEADINGS; REFERENCES.  Descriptive headings of
the 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

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




         Success Bancshares, Inc., a corporation organized and existing under
the General Corporation Law of the State of Delaware (the "CORPORATION"), does
hereby certify that, pursuant to authority conferred upon its Board of Directors
(the "BOARD OF DIRECTORS") by its Certificate of Incorporation, as amended, and
by the provisions of Section 151 of the General Corporation Law of the State of
Delaware, the following resolution was adopted by its Board of Directors by
unanimous written consent on May 27, 1998.

         RESOLVED, that, pursuant to the authority conferred upon the Board of
Directors by the provisions of the Certificate of Incorporation, as amended, of
the Corporation and by the provisions of Section 151 of the General Corporation
Law of the State of Delaware, there is hereby created a series of Preferred
Stock of the Corporation, which series shall have the following powers,
designations, preferences and relative, participating, optional and other
special rights, and the qualifications, limitations or restrictions thereof, in
addition to those set forth in the Second Restated Certificate of Incorporation
of the Corporation:

         Section 1.  Designation of Series; Number of Shares.  The series of
Preferred Stock established hereby shall be designated the "Series B Junior
Participating Preferred Stock" (the "SERIES B PREFERRED STOCK"), par value $.001
per share, and the authorized number of shares constituting the Series B
Preferred Stock shall be 90,000.  Such number of authorized shares may be
increased or decreased, from time to time, by resolution of the Board of
Directors; provided, however, that no such decrease shall reduce the number of
authorized shares of the Series B Preferred Stock to a number less than the
number of shares of the Series B Preferred Stock then outstanding, plus the
number of shares of the Series B Preferred Stock then reserved for issuance upon
the exercise of any outstanding options, warrants or 


                                     A-1


<PAGE>   42


rights or the exercise of any conversion or exchange privilege contained in any
outstanding security issued by the Corporation.

         Section 2.  Dividends and Distributions. (A) Subject to the rights of
the holders of shares of any other series of the Preferred Stock (or shares of
any other class of capital stock of the Corporation) ranking senior to the
Series B Preferred Stock with respect to dividends, the holders of shares of the
Series B Preferred Stock, in preference to the holders of shares of Common Stock
and of any other class of capital stock of the Corporation ranking junior to the
Series B Preferred Stock with respect to dividends, shall be entitled to
receive, when, as and if declared by the Board of Directors out of funds legally
available therefor, quarterly dividends payable in cash on the first day of
July, October, January and April in each year (each such date being a "DIVIDEND
PAYMENT DATE"), commencing on the first Dividend Payment Date after the initial
issuance of a share or fractional share of the Series B Preferred Stock, in an
amount per share (rounded to the nearest whole cent) equal to the greater of (a)
$1.00 and (b) 100 times the aggregate per share amount of all cash dividends,
plus 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 distribution in connection with the subdivision of the
outstanding shares of Common Stock, by reclassification or otherwise), declared
on the Common Stock since the immediately preceding Dividend Payment Date or,
with respect to the first Dividend Payment Date, since the initial issuance of a
share or fractional share of the Series B Preferred Stock.  The multiple of 100
(the "DIVIDEND MULTIPLE") set forth in the preceding sentence shall be adjusted
from time to time as hereinafter provided in this paragraph (A).  In the event
that the Corporation shall at any time after the effective date hereof (i)
declare or pay any dividend on the Common Stock payable in shares of Common
Stock or (ii) effect a subdivision, 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 Dividend Multiple
thereafter applicable to the determination of the amount of dividends per share
which the holders of shares of the Series B Preferred Stock shall be entitled to
receive shall be the Dividend Multiple in effect immediately prior to such event
multiplied by a fraction, the numerator of which shall be the number of shares
of Common Stock outstanding immediately after such event and the denominator of
which shall be the number of shares of Common Stock that were outstanding
immediately prior to such event.  As used herein, the term "effective date
hereof" shall mean August 10, 1998.

         (B)  The Board of Directors shall declare, out of funds legally
available therefor, a dividend or distribution on the Series B Preferred Stock,
as provided in paragraph (A) of this Section 2, immediately after it has
declared a dividend or distribution on the Common Stock (other than a dividend
payable in shares of Common Stock); provided, however, that, in the event that
no dividend or distribution shall have been declared on the Common Stock during
the period between any Dividend Payment Date and the next subsequent Dividend
Payment Date, a dividend of $1.00 per share on the Series B Preferred Stock less
an amount equal to the dividends already paid on the Series B Preferred Stock
during such period shall nevertheless be payable on such subsequent Dividend
Payment Date.

         (C)  Dividends shall begin to accrue and be cumulative on the
outstanding shares of the Series B Preferred Stock from the Dividend Payment
Date next preceding the date of issuance of such shares, unless such date of
issuance shall be prior to the record date for the first Dividend Payment Date,
in which case dividends on such shares shall begin to 


                                     A-2


<PAGE>   43


accrue and be cumulative from the date of issuance of such shares, or
unless such date of issuance shall be after the close of business on the record
date with respect to any Dividend Payment Date and on or prior to such Dividend
Payment Date, in which case dividends on such shares shall begin to accrue and
be cumulative from such Dividend Payment Date.  Accrued but unpaid dividends
shall not bear interest.  Dividends paid on shares of the Series B Preferred
Stock in an amount less than the total amount of dividends then accrued shall be
allocated pro rata among such shares.  The Board of Directors may fix a record
date for the determination of the holders of shares of the Series B Preferred
Stock entitled to receive payment of any dividend or distribution declared
thereon, which record date shall be not more than the number of days prior to
the date fixed for such payment permitted by applicable law.

     Section 3.  Voting Rights.  In addition to any other voting rights
required by applicable law, the holders of shares of the Series B Preferred
Stock shall have the following voting rights:

     (A) Each share of the Series B Preferred Stock shall entitle the holder
thereof to 100 votes on all matters submitted to a vote of the stockholders of
the Corporation.  The multiple of 100 (the "VOTING MULTIPLE") set forth in the
preceding sentence shall be adjusted from time to time as hereinafter provided
in this paragraph (A).  In the event that the Corporation shall at any time
after the effective date hereof (i) declare or pay any dividend on the Common
Stock payable in shares of Common Stock or (ii) effect a subdivision,
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 Voting Multiple thereafter applicable to the determination of
the number of votes per share to which the holders of shares of the Series B
Preferred Stock shall be entitled shall be the Voting Multiple in effect
immediately prior to such event multiplied by a fraction, the numerator of
which shall be the number of shares of Common Stock outstanding immediately
after such event and the denominator of which shall be the number of shares of
Common Stock that were outstanding immediately prior to such event.

     (B) Except as otherwise provided herein, in any other resolution of the
Board of Directors establishing another series of the Preferred Stock (or any
series of any other class of capital stock of the Corporation) or by applicable
law, the holders of the Series B Preferred Stock, the holders of the Common
Stock and the holders of any other class of capital stock of the Corporation
having general voting rights shall vote together as a single class on all
matters submitted to a vote of the stockholders of the Corporation.

     (C) (i) Whenever, at any time or times, dividends payable on any share or
shares of Series B Preferred Stock shall be in arrears in an amount equal to at
least six full quarterly dividends (whether or not declared and whether or not
consecutive), the holders of record of the outstanding Series B Preferred Stock
shall have the exclusive right, voting separately as a single class, to elect
two directors of the Corporation at a special meeting of stockholders of the
Corporation or at the Corporation's next annual meeting of stockholders, and at
each subsequent annual meeting of stockholders, as provided below.  At
elections for such directors, the holders of shares of Series B Preferred Stock
shall be entitled to cast one vote for each one one-hundredth of a share of
Series B Preferred Stock held.



                                      A-3


<PAGE>   44


         (ii)  Upon the vesting of such right of the holders of the Series B
Preferred Stock, the maximum authorized number of members of the Board of
Directors shall automatically be increased by two and the two vacancies so
created shall be filled by vote of the holders of the outstanding Series B
Preferred Stock as hereinafter set forth.  A special meeting of the stockholders
of the Corporation then entitled to vote shall be called by the Chairman or the
President or the Secretary of the Corporation, if requested in writing by the
holders of record of not less than 10% of the Series B Preferred Stock then
outstanding.  At such special meeting, or, if no such special meeting shall have
been called, then at the next annual meeting of stockholders of the Corporation,
the holders of the shares of the Series B Preferred Stock shall elect, voting as
above provided, two directors of the Corporation to fill the aforesaid vacancies
created by the automatic increase in the number of members of the Board of
Directors.  At any and all such meetings for such election, the holders of a
majority of the outstanding shares of the Series B Preferred Stock shall be
necessary to constitute a quorum for such election, whether present in person or
by proxy, and such two directors shall be elected by the vote of at least a
plurality of shares held by such stockholders present or represented at the
meeting.  Any director elected by holders of shares of the Series B Preferred
Stock pursuant to this Section may be removed at any annual or special meeting,
by vote of a majority of the stockholders voting as a class who elected such
director, with or without cause.  In case any vacancy shall occur among the
directors elected by the holders of the Series B Preferred Stock pursuant to
this Section, such vacancy may be filled by the remaining director so elected,
or his successor then in office, and the director so elected to fill such
vacancy shall serve until the next meeting of stockholders for the election of
directors.  After the holders of the Series B 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 further
increased or decreased except by vote of the holders of Series B Preferred Stock
as herein provided or pursuant to the rights of any equity securities ranking
senior to or pari passu with the Series B Preferred Stock.

         (iii) The right of the holders of the Series B Preferred Stock, voting
separately as a class, to elect two members of the Board of Directors of the
Corporation as aforesaid shall continue until, and only until, such time as all
arrears in dividends (whether or not declared) on the Series B Preferred Stock
shall have been paid or declared and set apart for payment, at which time such
right shall terminate, except as herein or by law expressly provided, subject to
revesting in the event of each and every subsequent default of the character
above-mentioned.  Upon any termination of the right of the holders of the shares
of the Series B Preferred Stock as a class to vote for directors as herein
provided, the term of office of all directors then in office elected by the
holders of Series B Preferred Stock pursuant to this Section shall terminate
immediately.  Whenever the term of office of the directors elected by the
holders of the Series B Preferred Stock pursuant to this Section shall terminate
and the special voting powers vested in the holders of the Series B Preferred
Stock pursuant to this Section shall have expired, the maximum number of members
of the Board of Directors of the Corporation shall be such number as may be
provided for in the By-laws of the Corporation irrespective of any increase made
pursuant to the provisions of this Section.

     (D) Except as otherwise provided herein or by applicable law, the holders
of the Series B Preferred Stock shall have no special voting rights and their
consent shall not be required (except to the extent provided in paragraph (B)
of this Section 3) for the taking of any corporate action.

     Section 4.  Certain Restrictions.

     (A) Whenever dividends or other distributions payable on the Series B
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
outstanding shares of the Series B Preferred Stock shall have been paid in
full, the Corporation shall not:

         (i)   declare or pay dividends, or make any other distributions, on any
shares of any class of capital stock of the Corporation ranking junior (either
as to dividends or upon liquidation, dissolution or winding up of the
Corporation) to the Series B Preferred Stock;

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

         (iii) redeem, purchase or otherwise acquire for consideration any
shares of any class of capital stock of the Corporation ranking junior (either
as to dividends or upon liquidation, dissolution or winding up of the
Corporation) to the Series B Preferred Stock, except that the Corporation may at
any time redeem, purchase or otherwise acquire any shares of such junior stock
in exchange for other shares of any class of capital stock of the Corporation
ranking junior (both as to dividends and upon dissolution, liquidation or
winding up of the Corporation) to the Series B Preferred Stock; or

         (iv)  purchase or otherwise acquire for consideration any shares of the
Series B Preferred Stock or any shares of any class of capital stock of the
Corporation ranking on a parity (either as to dividends or upon liquidation,
dissolution or winding up of the Corporation) with the Series B Preferred Stock,
or redeem any shares of such parity stock, except in accordance with a purchase
offer made in writing or by publication (as determined by the Board of
Directors) to the holders of all such shares upon such terms and conditions as
the Board of Directors, after taking into consideration the respective annual
dividend rates and the other relative powers, preferences and rights of the
respective series and classes of such shares, shall determine in good faith will
result in fair and equitable treatment among the respective holders of shares of
all such series and classes.

     (B) The Corporation shall not permit any subsidiary of the Corporation to
purchase or otherwise acquire for consideration any shares of any class of
capital stock of the Corporation unless the 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 the Series B Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and canceled promptly after such purchase or acquisition. All
such canceled shares shall thereupon become authorized and unissued shares of
Preferred Stock and may be reissued as part of any new series of the Preferred
Stock, subject to the conditions and restrictions on issuance set forth in the
Certificate of Incorporation of the Corporation, as amended from time to time,
in any other resolution of the Board of Directors establishing another series
of the 



                                      A-5


<PAGE>   46


Preferred Stock (or any series of any other class of capital stock of the
Corporation) or in any applicable law.

     Section 6.  Liquidation, Dissolution or Winding Up.  Upon any liquidation
(whether voluntary or otherwise), dissolution or winding up of the Corporation,
no distribution shall be made (a) to the holders of shares of any class of
capital stock of the Corporation ranking junior (either as to dividends or upon
liquidation, dissolution or winding up of the Corporation) to the Series B
Preferred Stock unless, prior thereto, the holder of each outstanding share of
the Series B Preferred Stock shall have received an amount equal to the accrued
and unpaid dividends and distributions thereon, whether or not declared, to the
date of such payment, plus an amount equal to the Dividend Multiple (the
"SERIES B LIQUIDATION PREFERENCE").  Following payment in full of the Series B
Liquidation Preference, no additional distributions shall be made to the
holders of the Series B Preferred Stock unless, prior thereto, the holders of
the Common Stock shall have received an amount per share (the "COMMON
ADJUSTMENT") equal to the quotient obtained by dividing (i) the Series B
Liquidation Preference by (ii) the Dividend Multiple.  Following payment in
full of the Series B Liquidation Preference and the Common Adjustment in
respect of all outstanding shares of Series B Preferred Stock and Common Stock,
respectively, holders of the Series B Preferred Stock and holders of Common
Stock shall receive their relative and proportionate share of the remaining
assets to be distributed to them in the ratio of the Dividend Multiple to one
with respect to such Series B Preferred Stock and Common Stock, on a per-share
basis.

     Section 7.  Consolidation, Merger, etc.  In the event that the Corporation
shall be a party to any consolidation, merger, combination or other transaction
in which the outstanding shares of Common Stock are converted or changed into
or exchanged for other capital stock, securities, cash or other property, or
any combination thereof, then, in each such case, each share of the Series B
Preferred Stock shall at the same time be similarly converted or changed into
or exchanged for an aggregate amount, subject to adjustment as hereinafter
provided in this Section 7, equal to 100 times the aggregate amount of capital
stock, securities, cash and/or other property (payable in kind), as the case
may be, into which or for which each share of Common Stock is being converted
or changed or exchanged.  In the event that the Corporation shall at any time
after the effective date hereof (a) declare or pay any dividend on the Common
Stock payable in shares of Common Stock or (b) effect a subdivision,
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 per share which the holders of shares of the
Series B Preferred Stock shall thereafter be entitled to receive pursuant to
the preceding sentence shall be the aggregate amount per share in effect
pursuant to such sentence immediately prior to such event multiplied by a
fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately after such event and the denominator of which shall be
the number of shares of Common Stock that were outstanding immediately prior to
such event.

     Section 8.  No Redemption.  The shares of the Series B Preferred Stock
shall not be redeemable at any time.

     Section 9.  Rank.  Unless otherwise provided in the resolution of the
Board of Directors establishing another series of the Preferred Stock after the
effective date hereof, the Series B Preferred Stock shall rank, as to the
payment of dividends and the making of any 


                                      A-6


<PAGE>   47


other distribution of assets of the Corporation, senior to the Common Stock, but
junior to all other series of the Preferred Stock.

         Section 10.  Amendments.  The Certificate of Incorporation of the
Corporation shall not be amended in any manner which would materially alter or
change the powers, preferences and rights of the Series B Preferred Stock so as
to adversely affect any thereof without the affirmative vote of the holders of
a majority of the outstanding shares of the Series B Preferred Stock, voting
separately as a single class.

         Section 11.  Fractional Shares.  Fractional shares of the Series B
Preferred Stock may be issued, but, unless the Board of Directors shall
otherwise determine, only in multiples of one one-hundredth of a share.  The
holder of any fractional share of the Series B Preferred Stock shall be
entitled to receive dividends, participate in distributions, exercise voting
rights and have the benefit of all other powers, preferences and rights
relating to the Series B Preferred Stock in the same proportion as such
fractional share bears to a whole share.

of Designations to be executed and attested by its duly authorized officers

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

appropriate by the Board) or (ii) under certain circumstances, may be
exchanged, in whole or in part, at the direction of the Board, for shares of
Common Stock of the Company or Preferred Shares at an exchange rate (subject to
adjustment) of one share of Common Stock or one one-hundredth of a Preferred
Share per Right.

     No fractional Preferred Share will be issued upon the exercise of any
Rights represented hereby (other than fractions which are a multiple of one
one-hundredth of a Preferred Share), but in lieu thereof a cash payment will be
made as provided in the Rights Agreement.

     No holder, as such, of this Rights Certificate shall be entitled to vote,
to receive dividends or other distributions on or to exercise any preemptive
rights with respect to, or shall be deemed for any other purpose to be the
holder of, the Preferred Shares or other shares of capital stock of any class
of the Company which may at any time be issuable upon exercise hereof; nor
shall anything contained herein or in the Rights Agreement 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
other matter submitted to stockholders at any meeting thereof, to give or
withhold consent to any corporate action, to receive notice of meetings or
other actions affecting stockholders (except as provided in the Rights
Agreement) or to receive dividends, subscription rights or other distributions,
until the Rights evidenced by this Rights Certificate shall have been
exercised, in whole or in part, in accordance with the provisions of 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 SHARES OF PREFERRED STOCK

     The Board of Directors (the "Board") of Success Bancshares, Inc., a
Delaware corporation (the "Company"), has declared a dividend of one preferred
stock purchase right (a "Right") for each outstanding share of Common Stock of
the Company (the "Common Stock").  The dividend is payable on August 10, 1998
("Record Date") to the holders of record of the Common Stock at the Close of
Business on such date.  Each Right entitles the holder thereof (except as
described below) to purchase from the Company one one-hundredth of a share of
the Series B Junior Participating Preferred Stock, $0.01 par value (the
"Preferred Shares"), of the Company at a price (the "Exercise Price") of $55.00
per one one-hundredth of a Preferred Share, subject to adjustment.  The terms
of the Rights are set forth in the Rights Agreement, dated August 1, 1998 (the
"Rights Agreement"), between the Company and Harris Trust and Savings Bank, as
Rights Agent (the "Rights Agent").  The capitalized terms not defined herein
have the respective meanings specified in the Rights Agreement.

     Distribution Date; Transfer of Rights.
     ------------------ -------------------

     Initially, the Rights associated with the Common Stock outstanding as of
the Record Date will be evidenced solely by the stock certificates for such
Common Stock, with a copy of this Summary of Rights attached thereto.  The
Rights will separate from the Common Stock upon the earliest to occur of (i) 10
Business Days after the first public announcement that any Person (other than
an Exempt Person (as hereinafter defined)) has become an Acquiring Person (as
hereinafter defined), and (ii) 10 Business Days (or such other Business Day as
may be determined by action of the Board prior to the time that any Person
shall become an Acquiring Person) after the commencement by any Person (other
than an Exempt Person) of, or the first public announcement of its intention to
commence, a tender or exchange offer if, upon the consummation thereof, such
Person would be the Beneficial Owner of 15% or more of the outstanding shares
of Common Stock (the earliest of the dates specified in clauses (i) and (ii)
being hereinafter called the "Distribution Date"). After the Distribution Date,
the Rights will be evidenced solely by separate certificates and will trade
independently from the Common Stock.

     An "Acquiring Person" is any Person who or which, together with its
Affiliates and Associates, has acquired 15% or more of the shares of Common
Stock then outstanding, but does not include (i) the Company, (ii) any
Subsidiary of the Company, (iii) any employee benefit plan or other
compensation program or arrangement of the Company or of any such Subsidiary or
(iv) any Person holding shares of Common Stock for or pursuant to the terms of
any such plan, program or arrangement (the Persons specified in clauses (i)
through (iv) being herein collectively called "Exempt Persons").  A "Continuing
Director" is (i) any member of the Board who is not a Restricted Person (as
hereinafter defined), or a representative or nominee of a Restricted Person,
and was a member of the Board prior to the date of the Rights Agreement and
(ii) any individual who subsequently becomes a member of the Board and is not a
Restricted Person, or a representative or nominee of a Restricted Person, and
whose nomination for election to the Board is recommended or approved by a
majority of the Continuing Directors then in office.  A "Restricted Person" is
an Acquiring Person, or any Affiliate or Associate thereof.



                                      C-1


<PAGE>   55


     The Rights Agreement provides that, until the Distribution Date (or the
earlier redemption or expiration of the Rights), the Rights may be transferred
only with the associated shares of Common Stock.  Until the Distribution Date
(or the earlier redemption or expiration of the Rights), stock certificates for
Common Stock issued after the Record Date, either upon transfer of outstanding
shares or original issuance of additional shares of Common Stock, will contain a
legend incorporating the Rights Agreement by reference.  Until the Distribution
Date (or the earlier redemption or expiration of the Rights), the surrender for
transfer of any stock certificate for shares of Common Stock, with or without
such legend and whether or not a copy of this Summary of Rights is attached
thereto, will also constitute the transfer of the Rights associated with the
shares of Common Stock represented by such stock certificate.

     As soon as practicable after the Distribution Date, separate certificates
evidencing the Rights ("Rights Certificates") will be mailed to the holders of
record of the Common Stock as of the Close of Business on the Distribution Date,
which thereafter will constitute the sole evidence of the Rights.  Each share of
Common Stock issued by the Company after the Record Date and prior to the
earlier redemption or expiration of the Rights, including any shares of Common
Stock issued by reason of the exercise of any option, warrant, right (other than
the Rights) or conversion or exchange privilege (however evidenced) issued by
the Company prior to the Distribution Date, will be accompanied by a Right
(unless the Board expressly provides to the contrary at the time of issuance of
any such option, warrant, right or privilege), and Rights Certificates
evidencing such Rights will be issued at the same time as the stock certificates
for the associated shares of Common Stock.

     The Rights are not exercisable until the Distribution Date.  Moreover, the
time when the Rights may be exercised is restricted as described in the next
paragraph.  The Rights will expire in ten (10) years (the "Final Expiration
Date"), unless the Final Expiration Date is extended or unless the Rights are
earlier redeemed or exchanged by the Company, in each case as described below.

     Exercise of Rights Under Certain Circumstances.

     In the event that any Person (other than the Company, its affiliates and
any Person receiving newly-issued shares of Common Stock directly from the
Company) becomes an Acquiring Person, proper provision will be made so that the
registered holder of each Right (other than Rights Beneficially Owned as
described in the next sentence) will thereafter have the right to receive, upon
exercise thereof, the number of shares of Common Stock which, at the time of the
occurrence of such event, will have a market value equal to two times the then
current Exercise Price.  After the first occurrence of either of the events
described in the preceding sentence, all Rights which are, or (under certain
circumstances specified in the Rights Agreement) were, Beneficially Owned by a
Restricted Person or specified transferees therefrom will be void. Under no
circumstances may a Right be exercised after the occurrence of either such event
unless the Company's right to redeem the Rights (as described below) has
expired.

     If, on or after the date on which any Person has become an Acquiring
Person, any of the following transactions occur:  (i) the Company merges into or
consolidates with an Interested Stockholder (as hereinafter defined) or, unless
all holders of the Company's outstanding shares of Common Stock are treated the
same, another Person (with limited 
 


                                     C-2


<PAGE>   56


designated exceptions); (ii) an Interested Stockholder or, unless all holders of
the Company's outstanding shares of Common Stock are treated the same, another
Person (with limited designated exceptions) merges into the Company and either
(A) all or part of the outstanding shares of Common Stock of the Company are
converted into capital stock or other securities of any other Person (or the
Company), cash and/or other property or (B) such shares remain outstanding,
unconverted and unchanged; or (iii) the Company sells or transfers 50% or more
of its consolidated assets or earning power to an Interested Stockholder (as
hereinafter defined) or, unless all holders of the Company's outstanding shares
of Common Stock are treated the same, another Person (with limited designated
exceptions); proper provision will be made so that the registered holder of each
Right (other than Rights which have become void) will thereafter have the right
(the "Flip-Over Right") to receive, upon exercise thereof, the number of common
shares of the acquiror (or of another Person affiliated therewith) which, at the
time of consummation of such transaction, will have a market value equal to two
times the then current Exercise Price.  An "Interested Stockholder" is any
Restricted Person or any Affiliate or Associate of any other Person in which
such Restricted Person has an interest, or any Person acting, directly or
indirectly, on behalf of or in concert with any such Restricted Person.

     Adjustments to Exercise Price and Stock Purchasable Upon Exercise.

     The Exercise Price payable, the number and kind of shares of capital stock
issuable upon exercise of the Rights and the number of Rights outstanding are
subject to adjustment from time to time to prevent dilution (i) in the event of
a dividend payable in Preferred Shares on, or a subdivision, combination or
reclassification of, the Preferred Shares, (ii) upon the grant to the holders of
the Preferred Shares of certain options, warrants or rights to subscribe for or
purchase Preferred Shares at a price, or securities convertible into or
exchangeable for Preferred Shares with a conversion or exchange price, less than
the then Fair Market Value of the Preferred Shares or (iii) upon the
distribution to the holders of the Preferred Shares of cash, securities,
evidences of indebtedness or other property (other than a regular quarterly cash
dividend or a dividend payable in Preferred Shares) or options, warrants or
rights (other than those referred to in clause (ii) above).

     The number of outstanding Rights and the number of one one-hundredths of a
Preferred Share issuable upon exercise of each Right are also subject to
adjustment in the event of a dividend on the Common Stock payable in shares of
Common Stock or a subdivision, combination or reclassification of the Common
Stock occurring, in any such case, prior to the Distribution Date.

     With certain specified exceptions, no adjustment in the Exercise Price will
be made until the cumulative adjustments required equal at least 1% of the
Exercise Price.  The Company is not required to issue fractional Preferred
Shares (other than fractions which are multiples of one one-hundredth of a
Preferred Share), but in lieu thereof the Company would be required to make a
cash payment based on the Fair Market Value of the Preferred Shares on the
trading day immediately preceding the date of exercise.

     Terms of Preferred Shares.

     The Preferred Shares receivable upon exercise of the Rights will not be
redeemable.  Each Preferred Share will entitle the holder thereof to receive a
preferential quarterly dividend equal to the greater of (i) $1.00 and (ii) 100
times the aggregate per share 
 


                                     C-3


<PAGE>   57


amount of all cash dividends, plus 100 times the aggregate per share amount
(payable in kind) of all non-cash dividends and other distributions (other than
in shares of Common Stock), declared on the Common Stock during such quarter,
adjusted to give effect to any dividend on the Common Stock payable in shares of
Common Stock or any subdivision, combination or reclassification of the Common
Stock (a "Dilution Event").  Each Preferred Share will entitle the holder
thereof to 100 votes on all matters submitted to a vote of the stockholders of
the Company, voting together as a single class with the holders of the Common
Stock and the holders of any other class of capital stock having general voting
rights, adjusted to give effect to any Dilution Event.  In the event of
liquidation of the Company, the holder of each Preferred Share will be entitled
to receive a preferential liquidation payment equal to 100 times the aggregate
per share amount to be distributed to the holders of the Common Stock, adjusted
to give effect to any Dilution Event, plus an amount equal to accrued and unpaid
dividends and distributions on such Preferred Share, whether or not declared, to
the date of such payment.  In the event of any merger, consolidation or other
transaction in which the outstanding shares of Common Stock of the Company are
exchanged for or converted into other capital stock, securities, cash and/or
other property, each Preferred Share will be similarly exchanged or converted
into 100 times the per share amount applicable to the Common Stock, adjusted to
give effect to any Dilution Event.

     Because of the nature of the dividend, voting, liquidation and other rights
accorded to each Preferred Share, the value of the one one-hundredth of a
Preferred Share receivable upon the exercise of each Right should approximate
the value of one share of Common Stock.

     Redemption of Rights.

     At any time prior to the earliest of (i) 10 Business Days after the first
public announcement that any Person (other than an Exempt Person) has become an
Acquiring Person, (ii) the occurrence of any transaction which permits the
exercise of the Flip-Over Right and (iii) the Final Expiration Date, the Board
may redeem all, but not less than all, of the Rights at the redemption price of
$.001 per Right, adjusted to give effect to any Dilution Event (the "Redemption
Price"); provided, however, that, under certain circumstances specified in the
Rights Agreement, the Rights may not be redeemed unless there are Continuing
Directors in office and such redemption is approved by at least a majority of
such Continuing Directors.  The redemption of the Rights may be made effective
at such time, on such basis and with such conditions as the Board, in its sole
discretion, may establish.  After the redemption period has expired, the
Company's right of redemption may be reinstated, under the circumstances
specified in the Rights Agreement, which include the concurrence of at least a
majority of the Continuing Directors, if either (i) the Person who became an
Acquiring Person shall reduce, in one or a series of related transactions not
involving the Company or any Subsidiary or the occurrence of any transaction
which permits the exercise of the Flip-Over Right, its Beneficial Ownership of
the outstanding shares of Common Stock to less than 15% of such outstanding
shares or (ii) in connection with any transaction which permits the exercise of
the Flip-Over Right, which does not involve an Interested Stockholder and in
which all holders of the Common Stock are treated the same.  Immediately after
action by the Board directing the redemption of the Rights, the option to
exercise the Rights will terminate, and thereafter each registered holder of the
Rights will only be entitled to receive the Redemption Price therefor.

     Exchange of Rights.

 

                                     C-4


<PAGE>   58


     At any time after any Person has become an Acquiring Person and prior to
the time that any Person (other than an Exempt Person), together with its
Affiliates and Associates, has become the Beneficial Owner of 50% or more of the
outstanding shares of Common Stock, the Board may direct that all or any part of
the outstanding Rights (other than Rights which have become void) be exchanged
for shares of Common Stock at the exchange rate of one share of Common Stock (or
one one-hundredth of a Preferred Share or of another share of capital stock of
the Company having equivalent rights, preferences and privileges) per Right,
adjusted to give effect to any Dilution Event.

     Amendment of the Rights and the Rights Agreement.

     Prior to the Distribution Date, the terms of the Rights and the Rights
Agreement may be supplemented or amended by the Board in any manner.  From and
after the Distribution Date, the Rights may be supplemented or amended by the
Board, without the approval of the holders of the Rights, in certain respects
which do not adversely affect, as determined by the Board (with the concurrence
of at least a majority of the Continuing Directors), the interests of such
holders; provided, however, that the Rights Agreement cannot be amended to
lengthen (i) any time period unless (A) such lengthening is approved by at least
a majority of the Continuing Directors and (B) such lengthening is for the
benefit of the holders of the Rights or (ii) any time period relating to when
the Rights may be redeemed if at such time the Rights are not then redeemable.

     Miscellaneous.

     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.

     A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission and 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 hereby
incorporated herein by reference.
