in all respects so as to protect and enhance the prestige of the parties, the
Developers, the Titles and the goodwill associated with them. The Units and
Components will be delivered to II free of defects in material and workmanship
in all material respects. II has the right to spot check and inspect the Units
and Components delivered by Affiliate. II may return inspected Units and
Components to Affiliate in cases where II finds reasonably unacceptable defect
rates, which shall be defined as three percent (3%) or more of each shipment.
Affiliate acknowledges that such inspection does not relieve Affiliate of any of
its obligations concerning quality of the Units or the Components.

      4.02  Packaging Design.

      (a) Affiliate shall consult with and obtain II's approval of all packaging
design and artwork prior to manufacturing Units of each Version.
Approval by II shall not be unreasonably withheld.

operating system, operating requirements such as memory, and bar code
information. Affiliate will shrink-wrap or otherwise provide secure closure for
all finished Units delivered to II. If II provides to Affiliate a label that
shows II's name and logo as distributor, Affiliate will affix the label to the
front of the outside of each Unit's packaging, provided that the label does not
obscure the title of the Title or the Affiliate's name or logo and is reasonable
in size.

            (i) Affiliate will provide to II, FOB at II's Designated Warehouse

for the first time in the Territory, no less than twenty-one (21) days in
advance of the Street Date, to enable II to timely distribute those

                                       6
<PAGE>   7
Units to its Customers. In the event those Units or Components are not timely
delivered, the terms of Section 3.01(c) shall also apply with respect to those
Units delivered by Affiliate to II as finished Units.

            (ii) Affiliate shall be responsible for adequately insuring the
Units for shipment FOB to II's warehouse located at Lancaster Distribution
Center, 1800 Cloister Drive, Lancaster, PA ("Designated Warehouse").

            (iii) II may cancel any Units which are to be delivered under any
purchase order, provided notice of cancellation is made in writing, no less than
thirty (30) days prior to the scheduled delivery date.

            (iv) Affiliate agrees to maintain a sufficient inventory of Units or
Components, as applicable, at a level equal to the most recent II forecast of
sales of each Version. In the event Affiliate is unable to provide delivery of a
Version pursuant to a II purchase order within thirty (30) days after receipt of
that order, II may cancel such undelivered purchase order and any or all
subsequent purchase orders for that Version.

      b.) II is not obligated to accept any partial delivery under any order. In
the event II accepts a partial delivery, the portion not shipped will be deemed
a separate order.

      4.04 Technical Support: Affiliate will provide technical support for each
Version in the Territory to II, Customers and End Users. Technical support will
include, without limitation, warranty service and phone support via a local or
toll-free telephone number. Affiliate will have personnel knowledgeable of the
technical and application aspects of each Version available to answer support
questions during regular business hours. During the Term of this Agreement each
party agrees to inform the other promptly of any known defects or operational
errors affecting any Version.

      4.05 Testing. Prior to delivery of Titles to II, Affiliate agrees to test
each Version to make certain that each Version is reasonably bug-free and fully
functional in the different configurations in which the Version is designated to
run and for all peripherals with which each Version is designated to work.
Without limiting the foregoing, if II is providing Manufacturing Services,
Affiliate shall prior to delivery to II so test each Master. Affiliate agrees to
provide II, upon delivery of the Units, or Master, as applicable, with each
Version's configuration testing reports prepared by Affiliate in the normal
course of its business, along with hint sheets and maps for all game, adventure,
simulation and role-playing Titles.

            (i) Advertising and publicizing each Version to Customers and
potential customers in trade publications, promoting each Title on Affiliate's

materials, and deduct an amount equal to the cost of goods from the Reserve or
from any monies otherwise owed to Affiliate under this agreement.

a form reasonably acceptable to II and shall be issued by an insurance company
with a rating of A or better as set forth in the most current Best Insurance
Guide. Affiliate shall add II as an additional insured/ to each policy and will
furnish certificates evidencing that insurance within ten (10) days of the date
first set forth above. In the event there are claims against any existing
insurance policy with respect to any Version, Affiliate will procure additional
insurance coverage which is necessary to maintain the minimum level of coverage
described in this subsection.

5.     TITLE AND RISK OF LOSS

       Title to Units shall pass from Affiliate to II upon shipment to II's
Customers. Risk of loss for Units and Components shall pass to II from Affiliate
upon delivery to II's Designated Warehouse. For Units returned to II by II's
Customers for which title has passed to those Customers, title will pass from
the Customer to Affiliate upon return to II. Risk of loss will remain with II
until re-delivery to Affiliate of returned Units or Components.

                                       9
<PAGE>   10
      6.03 Accounting.

         a.) II shall submit both Proceeds due, if any, and itemized statements
to Affiliate within sixty (60) days after the end of each month of the Term,
regardless of whether any Proceeds are payable to Affiliate for that affected
calendar month. The statements shall contain the following, separately reported
for each Title: Unit sales, Taxes, Returns, MDF, and all other costs permitted
to be deducted under the terms of this agreement. The statements shall otherwise
show separately for each Title in detail all calculations reasonably necessary
for the computation of Proceeds and a cumulative reconciliation of the number of
Units manufactured, Units sold, and Units remaining in inventory. All Proceeds
shall be paid on one hundred percent of all retail sales as reported by II's POS
Customers (currently, principally Wal-Mart, Target and K Mart), less returns,
and on one hundred percent (100%) of shipments to all other Customers, less a
Reserve (as defined below) for returns. In addition, reductions shall be taken
for Taxes, Price Protection and MDF, if applicable, and if returns exceed the
Reserve. Affiliate acknowledges that Units may be returned for any reason,
including overstock or due to defects. At II's option, II will debit against
amounts otherwise due Affiliate during each accounting period, deduct from the
Reserve, or require Affiliate to reimburse II for, all returned Units. Affiliate
will pay all transportation and shipping charges associated with such returns to
Affiliate. In addition, in the event of a recall based solely on errors in the
software code for any Version, Affiliate will pay all costs associated with the
recall including but not limited to Handling Charges, End User notification
costs, Unit replacement costs, and all freight costs. The term "Handling
Charges" will mean, for each Unit returned as the result of a recall, reasonable
labor and administrative costs plus all of II's out-of-pocket costs including,
without limitation, shipping and insurance costs related to the return and, if
applicable, replenishment of such defective Units to and from II to Customers,
and to and from II to Affiliate.

      b.) If the Wholesale Price of Units of any Version is lowered, Affiliate
will credit or refund to II, or II may deduct from monies otherwise payable to
Affiliate under this agreement, at II's option, the amounts credited or refunded
by II to its Customers by reason of the reduced Wholesale Price for the affected
Version ("Price Protection"). Affiliate acknowledges that II is dependent upon
prompt and reliable information from II's Customers to determine the inventory
to which Price Protection should apply. Affiliate agrees that (i) II shall have
the right to determine a good faith estimate of the inventory of its Customers,
and base the amount of Price Protection upon that estimate; and (ii) II may
adjust its estimate on a periodic basis as it receives additional information
from its Customers.

      c.) The amount withheld for the Reserve shall be equal to twenty percent
(20%) of the

                                       10
<PAGE>   11

held in an interest-bearing account and applied by II for returned Units, Price
Protection (as defined in subsection (b) above), co-op advertising and any other
credits, refunds or other amounts owed to II under this agreement, including
those owed upon the expiration or earlier termination of this agreement.

      d.) If II provides Manufacturing Services for any Units, Affiliate shall
pay to II the total Manufacturing Fee for those affected Units. II shall, at its
option, (i) offset the total Manufacturing Fee from Proceeds, in which case II
shall provide a detailed invoice reflecting the calculation of the Manufacturing
Fee along with each statement provided pursuant to subsection (c) above, or (ii)
invoice Affiliate for the total Manufacturing Fee at the end of each month
during which Manufacturing Services are provided. If II invoices Affiliate,
Affiliate shall pay the applicable Manufacturing Fee within forty-five (45) days
of its receipt of each invoice.

6.04 Audit

      II shall maintain for a period of two (2) years after the end of the year
to which they pertain, complete records of the Units sold and distributed by II
in order to calculate and confirm II's payment obligations hereunder. Upon
reasonable prior notice, Affiliate will have the right, exercisable not more
than once every twelve (12) months, at Affiliate's expense, to examine or have
its agents examine, such books, records and accounts during II's normal business
hours to verify the payments due by II to Affiliate herein, subject execution of
II's standard confidentiality agreement by such agents; provided, however, that
execution of such agreement will not preclude such agents from reporting results
to Affiliate. No audit shall take place during the first three (3) weeks of any
quarterly accounting period. If an audit shall reveal an underpayment by II of
ten percent (10%) or more for the period audited, II shall pay to Affiliate the
amount of the underpayment and the reasonable expenses of the audit up to the
amount of the underpayment.

harmless and defend II, its subsidiaries, affiliates and their respective
officers, directors and employees from and against all claims, losses, defense
costs (including reasonable attorneys' fees), judgments and other expenses
related to or arising out of: (a) the breach or alleged breach of its
representations, warranties and covenants; (b) any product liability with
respect to any Title; (c) the alleged infringement or violation of any
trademark, copyright, trade secret, patent or other proprietary

<PAGE>   16
right with respect to any Title; and (d) any unfair trade practice, trade libel
or misrepresentation based on any promotional material, packaging, documentation
or other materials provided by Affiliate with respect to any Title. Provided
that Affiliate is fulfilling its indemnification obligations hereunder in good
faith, Affiliate shall have the right to control the defense and settlement of
any such claim at Affiliate's expense and to choose counsel for such purpose,
provided that Affiliate may not settle any such claim without II's prior written
consent, which will not be unreasonably withheld. II may retain counsel (at II's
sole option and expense) with respect to any such claim, and Affiliate shall
ensure that its counsel reasonably cooperates with II's counsel in the course of
such defense. If Affiliate does not fulfill its indemnification obligations in
good faith, II will have the right to defend and settle any claim for which it
was entitled to indemnification under this agreement and to receive
reimbursement from Affiliate for all of its costs in defending and settling such
claim. In case an infringement claim is finally judicially determined to be an
infringement, Affiliate will, at Affiliate's sole option: (i) procure a license
from any claimants with respect to the challenged Title or any Version that will
enable II to continue marketing that Title or any Version (ii) modify the
Version or Title so as to make it noninfringing, or (iii) buy back all inventory

or Version.

Affiliate, its subsidiaries, affiliates and their respective officers, directors
and employees from and against all claims, losses, defense costs (including
reasonable attorneys' fees), judgments and other expenses arising out of: II's
representations, warranties and covenants. II's obligation to indemnify is
conditioned on Affiliate notifying II of any such claim as to which
indemnification will be sought promptly after Affiliate learns of such claim,
and providing II reasonable cooperation in the defense and settlement thereof.
Provided that II is fulfilling its indemnification obligations hereunder in good
faith, II shall have the right to control the defense and settlement of any such
claim at II's expense and to choose counsel for such purpose, provided that II
may not settle any such claim without Affiliate's prior written consent, which
will not be unreasonably withheld. Affiliate may retain counsel (at Affiliate's
sole option and expense) with respect to any such claim, and II shall ensure
that its counsel reasonably cooperates with Affiliate's counsel in the course of
such defense. If II does not fulfill its indemnification obligations in good
faith, Affiliate will have the right to defend and settle any claim for which it
was entitled to indemnification and to receive reimbursement from II for all of

                           SECOND AMENDED AND RESTATED

                        PREFERRED SHARES RIGHTS AGREEMENT

         This Second Amended and Restated Preferred Shares Rights Agreement (the
"RIGHTS AGREEMENT") between Cyberonics, Inc., a Delaware corporation (the
"COMPANY"), and BankBoston, N.A. (formerly known as The First National Bank of
Boston), a national banking association (the "RIGHTS AGENT") is dated and
effective as of August 21, 2000.

         WHEREAS, the Company and the Rights Agent are parties to that certain
Preferred Shares Rights Agreement dated as of March 4, 1997 (the "PRIOR RIGHTS
AGREEMENT"); and

         WHEREAS, on January 29, 1997 (the "RIGHTS DIVIDEND DECLARATION DATE"),
the Board of Directors of the Company authorized and declared a dividend of one
Preferred Share Purchase Right (a "RIGHT") for each Common Share (as hereinafter
defined) of the Company outstanding as of the Close of Business (as hereinafter
defined) on March 10, 1997 (the "RECORD DATE"), each Right representing the
right to purchase one one-thousandths of a share of Series A Participating
Preferred Stock (as such number may be adjusted pursuant to the provisions of
this Rights Agreement), having the rights, preferences and privileges set forth
in the form of Certificate of Designations of Rights, Preferences and Privileges
of Series A Participating Preferred Stock attached hereto as Exhibit A, upon the
terms and subject to the conditions herein set forth, and further authorized and
directed the issuance of one Right (as such number may be adjusted pursuant to
the provisions of this Rights Agreement) with respect to each Common Share that
shall become outstanding between the Record Date and the earlier of the
Distribution Date and the Expiration Date (as such terms are hereinafter
defined), and in certain circumstances after the Distribution Date; and

         WHEREAS, the Company, pursuant to Section 27 of the Prior Rights
Agreement, amended and restated the Prior Rights Agreement without the approval
of the holders of the Rights (as hereinafter defined); and

         WHEREAS, the Company and the Rights Agent are parties to that certain
First Amended and Restated Preferred Shares Rights Agreement, dated February 16,
2000 (the "FIRST AMENDED AND RESTATED RIGHTS AGREEMENT"); and

         WHEREAS, the Company has determined that, pursuant to Section 27 of the
First Amended and Restated Rights Agreement, as set forth herein, without the
approval of the holders of the Rights (as hereinafter defined);

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

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

            (a) "ACQUIRING PERSON" shall mean any Person who or which, together
with all Affiliates and Associates of such Person, shall be the Beneficial Owner
of 15% or more of the Common Shares then outstanding, but shall not include the
Company, any Subsidiary of the

                                        1
<PAGE>   5

Company or any employee benefit plan of the Company or of any Subsidiary of the
Company, or any entity holding Common Shares for, or pursuant to the terms of,
any such plan. Notwithstanding the foregoing, no Person shall be deemed to be an
Acquiring Person as the result of an acquisition of Common Shares by the Company
which, by reducing the number of shares outstanding, increases the proportionate
number of shares beneficially owned by such Person to 15% or more of the Common
Shares of the Company, then outstanding; provided, however, that if a Person
shall become the Beneficial Owner of 15% or more of the Common Shares of the
Company then outstanding by reason of share purchases by the Company and shall,
after such share purchases by the Company, become the Beneficial Owner of any
additional Common Shares of the Company (other than pursuant to a dividend or
distribution paid or made by the Company on the outstanding Common Shares in
Common Shares or pursuant to a split or subdivision of the outstanding Common
Shares), then such Person shall be deemed to be an Acquiring Person unless upon
becoming the Beneficial Owner of such additional Common Shares of the Company
such Person does not beneficially own 15% or more of the Common Shares of the
Company then outstanding. Notwithstanding the foregoing, (i) if the Company's
Board of Directors determines in good faith that a Person who would otherwise be
an "Acquiring Person," as defined pursuant to the foregoing provisions of this
paragraph (a), has become such inadvertently, and if such Person divested or
divests as promptly as practicable a sufficient number or Common Shares so that
such Person would no longer be an "Acquiring Person," as defined pursuant to the
foregoing provisions of this paragraph (a), then such Person shall not be deemed
to be or to have become an "Acquiring Person" for any purposes of this Rights
Agreement, and (ii) if, as of the date hereof, any Person is the Beneficial
Owner of 15% or more of the Common Shares outstanding, such Person shall not be
or become an "Acquiring Person," as defined pursuant to the foregoing provisions
of this paragraph (a), unless and until such time as Person shall become the
Beneficial Owner of additional Common Shares (other than pursuant to a dividend
or distribution paid or made by the Company on the outstanding Common Shares in
Common Shares or pursuant to a split or subdivision of the outstanding Common
Shares), unless, upon becoming the Beneficial Owner of such additional Common
Shares, such Person is not then the Beneficial Owner of 15% or more of the
Common Shares then outstanding.

            (b) "ADJUSTMENT FRACTION" shall have the meaning set forth in
Section 11(a)(i) hereof.

            (c) "AFFILIATE" and "ASSOCIATE" shall have the respective meanings
ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under
the Exchange Act, as in effect on the date of this Rights Agreement.

            (d) A Person shall be deemed the "BENEFICIAL OWNER" of and shall be
deemed to "BENEFICIALLY OWN" any securities:

                (i) which such Person or any of such Person's Affiliates or
Associates beneficially owns, directly or indirectly, for purposes of Section
13(d) of the Exchange Act and Rule 13d-3 thereunder (or any comparable or
successor law or regulation);

                (ii) which such Person or any of such Person's Affiliates or
Associates has (A) the right to acquire (whether such right is exercisable
immediately or only after the passage of time) pursuant to any agreement,
arrangement or understanding (other than customary

                                       -2-
<PAGE>   6

agreements with and between underwriters and selling groups members with respect
to a bona fide public offering of securities), or upon the exercise of
conversion rights, exchange rights, rights (other than the Rights), warrants or
options, or otherwise; provided, however, that a Person shall not be deemed
pursuant to this Section 1(d)(ii)(A) to be the Beneficial Owner of, or to
beneficially own, (1) 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 (2) securities which a Person or any of such Person's Affiliates or
Associates may be deemed to have the right to acquire pursuant to any merger or
other acquisition agreement between the Company and such Person (or one or more
of its Affiliates or Associates) if such agreement between the Company and such
Person (or one or more of its Affiliates or Associates) if such agreement has
been approved by the Board of Directors of the Company prior to there being an
Acquiring Person; or (B) the right to vote pursuant to any agreement,
arrangement or understanding; provided, however, that a Person shall not be
deemed the Beneficial Owner of, or to beneficially own, any security under this
Section 1(d)(ii)(B) if the agreement, arrangement or understanding to vote such
security (1) arises solely from a revocable proxy or consent given to such
Person in response to a public proxy or consent solicitation made pursuant to,
and in accordance with, the applicable rules and regulations of the Exchange Act
and (2) is not also then reportable on Schedule 13D under the Exchange Act (or
any comparable or successor report); or

                (iii) which are beneficially owned, directly or indirectly, by
any other Person (or any Affiliate or Associate thereof) with which such Person

            (a) Until the Distribution Date, (i) the Rights will be evidenced
(subject to the provisions of Sections 3(b) and 3(c) hereof) by the certificates
for Common Shares registered in the names of the holders thereof (which

separately and apart from any transfer of Common Shares, and the holders of such
Rights Certificates as listed

                                       -7-
<PAGE>   11

in the records of the Company or any transfer agent or registrar for the Rights
shall be the record holders thereof.

            (b) On the Record Date or as soon as practicable thereafter, the
Company will send a copy of the Summary of Rights by first-class,
postage-prepaid mail, to each record holder of Common Shares as of the Close of
Business on the Record Date, at the address of such holder shown on the records
of the Company's transfer agent and registrar. With respect to certificates for
Common Shares outstanding as of the Record Date, until the Distribution Date,
the Rights will be evidenced by such certificates registered in the names of the
holders thereof together with the Summary of Rights. Until the Distribution Date
(or, if earlier, the Expiration Date), the surrender for transfer of any
certificate for Common Shares outstanding on the Record Date, with or without a
copy of the Summary of Rights, shall also constitute the transfer of the Rights
associated with the Common Shares represented thereby.

            (c) Unless the Board of Directors by resolution adopted at or before
the time of the issuance of any Common Shares specifies to the contrary, Rights
shall be issued in respect of all Common Shares that are issued after the Record
Date but prior to the earlier of the Distribution Date or the Expiration Date
or, in certain circumstances provided in Section 22 hereof, after the
Distribution Date. Certificates representing such Common Shares shall also be
deemed to be certificates for Rights, and shall bear the following legend;
provided, however, that such certificates issued after the Record Date and prior
to approximately February 16, 2000, shall bear such legend upon transfer or
replacement only, and otherwise shall retain the legend currently thereon
referring to the First Amended and Restated Rights Agreement:

            THIS CERTIFICATE ALSO EVIDENCES AND ENTITLES THE HOLDER HEREOF TO
CERTAIN RIGHTS AS SET FORTH IN A SECOND AMENDED AND RESTATED PREFERRED SHARES
RIGHTS AGREEMENT BETWEEN CYBERONICS, INC. AND FIRST NATIONAL BANK OF BOSTON AS
THE RIGHTS AGENT, DATED AS OF AUGUST, 21 2000 (THE "RIGHTS AGREEMENT"), THE
TERMS OF WHICH ARE HEREBY INCORPORATED HEREIN BY REFERENCE AND A COPY OF WHICH
IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF CYBERONICS, INC. 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. CYBERONICS, INC. WILL MAIL TO THE HOLDER OF THIS CERTIFICATE A COPY
OF THE RIGHTS AGREEMENT WITHOUT CHARGE AFTER RECEIPT OF A WRITTEN REQUEST

ISSUED TO, OR HELD BY, ANY PERSON WHO IS, WAS OR BECOMES AN ACQUIRING PERSON OR
ANY AFFILIATE OR ASSOCIATE THEREOF (AS SUCH TERMS ARE DEFINED IN THE RIGHTS
AGREEMENT), WHETHER CURRENTLY HELD BY OR ON BEHALF OF SUCH PERSON OR BY ANY
SUBSEQUENT HOLDER, MAY BECOME NULL AND VOID.

         With respect to such certificates containing the foregoing legend,
until the earlier of (i) the Distribution Date or (ii) the Expiration Date, the
Rights associated with the Common Shares represented by such certificates shall
be evidenced by such certificates alone, and the

                                       -8-
<PAGE>   12

surrender for transfer of any such certificate shall also constitute the
transfer of the Rights associated with the Common Shares represented thereby.

            (d) In the event that the Company purchases or acquires any Common
Shares after the Record Date but prior to the Distribution Date, any Rights
associated with such Common Shares shall be deemed canceled and retired so that
the Company shall not be entitled to exercise any Rights associated with the
Common Shares which are no longer outstanding.

         4. Form of Rights Certificates

            (a) The Rights Certificates (and the forms of election to purchase
Common Shares and of assignment to be printed on the reverse thereof) shall be
substantially in the form of Exhibit B hereto and may have such marks of
identification or designation and such legends, summaries or endorsements
printed thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Rights Agreement, or as may be required to comply
with any applicable law or with any rule or regulation made pursuant thereto or
with any rule or regulation of any stock exchange or a national market system,
on which the Rights may from time to time be listed or included, or to conform
to usage. Subject to the provisions of Section 11 and Section 22 hereof, the
Rights Certificates, whenever distributed, shall be dated as of the Record Date
(or in the case of Rights issued with respect to Common Shares issued by the
Company after the Record Date, as of the date of issuance of such Common Shares)
and on their face shall entitle the holders thereof to purchase such number of
one-thousandths of a Preferred Share as shall be set forth therein at the price
set forth therein (such exercise price per one one-thousandth of a Preferred
Share being hereinafter referred to as the "EXERCISE PRICE" and the aggregate
Exercise Price of all Preferred Shares issuable upon exercise of one Right being
hereinafter referred to as the "TOTAL EXERCISE PRICE"), but the number and type
of securities purchasable upon the exercise of each Right and the Exercise Price
shall be subject to adjustment as provided herein.

            (b) Any Rights Certificate issued pursuant to Section 3(a) or
Section 22 hereof that represents Rights beneficially owned by: (i) an Acquiring
Person or any Associate or Affiliate of an Acquiring Person, (ii) a transferee
of an Acquiring Person (or of any such Associate or Affiliate) who becomes a
transferee after the Acquiring Person becomes such or (iii) a transferee of an
Acquiring Person (or of any such Associate or Affiliate) 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 the Acquiring Person to holders of equity interests in such
Acquiring Person or to any Person with whom such Acquiring Person has any
continuing agreement, arrangement or understanding regarding the transferred
Rights or (B) a transfer which a majority of the Company's Board of Directors
has determined is part of a plan, arrangement or understanding which has as a
primary purpose or effect avoidance of Section 7(e) hereof, and any Rights
Certificate issued pursuant to Section 6 or Section 11 hereof upon transfer,
exchange, replacement or adjustment of any other Rights Certificate referred to
in this sentence, shall contain (to the extent feasible) the following legend:

         THE RIGHTS REPRESENTED BY THIS RIGHTS CERTIFICATE ARE OR WERE
BENEFICIALLY OWNED BY A PERSON WHO WAS OR BECAME AN ACQUIRING PERSON OR AN
AFFILIATE OR ASSOCIATE OF AN ACQUIRING PERSON (AS SUCH

                                       -9-
<PAGE>   13

TERMS ARE DEFINED IN THE RIGHTS AGREEMENT). ACCORDINGLY, THIS RIGHTS CERTIFICATE
AND THE RIGHTS REPRESENTED HEREBY MAY BECOME NULL AND VOID IN THE CIRCUMSTANCES
SPECIFIED IN SECTION 7(E) OF THE RIGHTS AGREEMENT.

         5. Countersignature and Registration.

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

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

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

            (a) Subject to the provisions of Sections 7(e), 14 and 24 hereof, at
any time after the Close of Business on the Distribution Date, and at or prior
to the Close of Business on the Expiration Date, any Rights Certificate or
Rights Certificates may be transferred, split up, combined or exchanged for
another Rights Certificate or Rights Certificates, entitling the registered
holder to purchase a like number of one-thousandths of a Preferred Share (or,
following a Triggering Event, other securities, cash or other assets, as the
case may be) as the Rights Certificate or Rights Certificate surrendered then
entitled such holder to purchase. Any registered holder desiring to transfer,
split up, combine or exchange any Rights Certificate or Rights Certificates
shall make such request in writing delivered to the Rights Agent, and shall
surrender the Rights Certificate or Rights Certificates to be transferred, split
up, combined or exchanged at the office of the Rights Agent designated for such
purpose. Neither the Rights Agent nor the Company shall be obligated to take any
action whatsoever with respect to the transfer of any such surrendered Rights
Certificate until the registered holder shall have completed and signed the
certificate contained in the form of assignment on the reverse side of such
Rights Certificate and shall have provided such additional evidence of the
identity of the

                                      -10-
<PAGE>   14

Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates
thereof as the Company shall reasonably request. Thereupon the Rights Agent
shall, subject to Sections 7(e), 14 and 24 hereof, countersign and deliver to
the person entitled thereto a Rights Certificate or Rights Certificates, as the
case may be, as so requested. The Company may require payment of a 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.

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

Event, other securities, cash or other assets as the case may be) as to which

            (b) The Exercise Price for each one-thousandth of a Preferred Share

Fifty Dollars ($150.00), shall be subject to adjustment from time to time as
provided in Sections 11 and 13 hereof and shall be payable in lawful money of
the United States of America in accordance with paragraph (c) below.

            (c) Upon receipt of a Rights Certificate representing exercisable
Rights, with the form of election to purchase duly executed, accompanied by
payment of the Exercise Price for the number of one-thousandths of a Preferred
Share (or, following a Triggering Event, other securities, cash or other assets
as the case may be) to be purchased and an amount equal to any applicable
transfer tax required to be paid by the holder of such Rights Certificate in
accordance with Section 9(e) hereof, the Rights Agent shall, subject to Section
20(k) hereof, thereupon, promptly (i)(A) requisition from any transfer agent of
the Preferred Shares (or make available, if the Rights Agent is the transfer
agent for the Preferred Shares) a certificate or certificates for the number of
one-thousandths of a Preferred Share (or, following a Triggering Event, other
securities, cash or other assets as the case may be) to be purchased and the
Company hereby irrevocably authorizes its transfer agent to comply with all such
requests or (B) if the Company shall have elected to deposit the total number of

securities, cash or other assets as the case may be) issuable upon exercise of
the Rights hereunder with a depositary agent, requisition from the depositary

                                      -11-
<PAGE>   15

agent depositary receipts representing such number of one-thousandths of a
Preferred Share (or, following a Triggering Event, other securities, cash or
other assets as the case may be) as are to be purchased, in which case
certificates for the Preferred Shares (or, following a Triggering Agent, other
securities, cash or other assets as the case may be) represented by such
receipts shall be deposited by the transfer agent with the depositary agent) and
the Company hereby directs the depositary agent to comply with such request,
(ii) when appropriate, requisition from the Company the amount of cash to be
paid in lieu of issuance of fractional shares in accordance with Section 14
hereof, (iii) after receipt of such certificates or depositary receipts, cause
the same to be delivered to or upon the order of the registered holder of such
Rights Certificate, registered in such name or names as may be designated by
such holder and (iv) when appropriate, after receipt thereof, deliver such case
to or upon the order of the registered holder of such Rights Certificate. The
payment of the Exercise Price (as such amount may be reduced (including to zero)
pursuant to Section 11(a)(iii) hereof) and an amount equal to any applicable
transfer tax required to be paid by the holder of such Rights Certificate in
accordance with Section 9(e) hereof, may be made in cash or by certified bank
check, cashier's check or bank draft payable to the order of the Company. In the
event that the Company is obligated to issue securities of the Company other
than Preferred Shares, pay cash and/or distribute other property pursuant to
Section 11(a) hereof, the Company will make all arrangements necessary so that
such other securities, cash and/or other property are available for distribution
by the Rights Agent, if and when appropriate.

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

            (e) Notwithstanding anything in this Rights Agreement to the
contrary, from and after the first occurrence of a Triggering Event, any Rights
beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of an
Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) who becomes a transferee after the Acquiring Person
becomes such (a "POST-EVENT TRANSFEREE"), (iii) a transferee of an Acquiring
Person (or of any such Associate or Affiliate) 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 the
Acquiring Person to holders of equity interests in such Acquiring Person or to
any Person with whom the Acquiring Person has any continuing agreement,
arrangement or understanding regarding the transferred Rights or (B) a transfer
which a majority of the Company's Board of Directors has determined is part of a
plan, arrangement or understanding which has as a primary purpose or effect the
avoidance of this Section 7(e) (a "PRE-EVENT TRANSFER") or (iv) any subsequent
transferee receiving transferred Rights from a Post-Event Transferee or a
Pre-Event Transferee, either directly or through one or more intermediate
transferees, shall become null and void without any further action and no holder
of such Rights shall have any rights whatsoever with respect to such Rights
whether under any provision of this rights Agreement or otherwise. The Company
shall use all reasonable efforts to ensure that the provisions of this Section
7(e) and Section 4(b) hereof are complied with, but shall have no liability to
any holder of Rights Certificates or to any other Person as a

                                      -12-
<PAGE>   16

result of its failure to make any determinations with respect to an Acquiring
Person or any of such Acquiring Person's Affiliates, Associates or transferees
hereunder.

            (f) Notwithstanding anything in this Rights Agreement to the
contrary, neither the Rights Agent nor the Company shall be obligated to
undertaken any action with respect to a registered holder upon the occurrence of
any purported exercise as set forth in this Section 7 unless such registered
holder shall, in addition to having complied with the requirements of Section
7(a) above, have (i) completed and signed the certificate contained in the form
of election to purchase set forth on the reverse side of the Rights Certificate
surrendered for such exercise and (ii) provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request.

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

         9. Reservation and Availability of Preferred Shares.

            (a) The Company covenants and agrees that it will use its best
efforts to cause to be reserved and kept available out of its authorized and
unissued Preferred Shares not reserved for another purpose (and, following the
occurrence of a Triggering Event, out of its authorized and unissued Common
Shares and/or other securities), the number of Preferred Shares (and, following
the occurrence of the Triggering Event, Common Shares and/or other securities )
that will be sufficient to permit the exercise in full of all outstanding
Rights.

            (b) If the Company shall hereafter list any of its Preferred Shares
on a national securities exchange, then so long as the Preferred Shares (and,
following the occurrence of a Triggering Event, Common Shares and/or other
securities) issuable and deliverable upon exercise of the Rights may be listed
on such exchange, the Company shall use its best efforts to cause, from and
after such time as the Rights become exercisable (but only to the extent that it
is reasonably likely that the Rights will be exercised), all shares reserved for
such issuance to be listed on such exchange upon official notice of issuance
upon such exercise.

            (c) The Company shall use its best efforts to (i) file, as soon as
practicable following the earliest date after the first occurrence of a
Triggering Event in which the consideration to be delivered by the Company upon
exercise of the Rights is described in Section 11(a)(ii) or Section 11(a)(iii)
hereof, or as soon as is required by law following the Distribution Date, as the
case may be, a registration statement under the Securities Act with respect to
the

                                      -13-
<PAGE>   17

securities purchasable upon exercise of the Rights on an appropriate form, (ii)
cause such registration statement to become effective as soon as practicable
after such filing and (iii) cause such registration statement to remain
effective (with a prospectus at all times meeting the requirements of the
Securities Act) until the earlier of (A) the date as of which the Rights are no
longer exercisable for such securities and (B) the date of expiration of the
Rights. The Company may temporarily suspend, for a period not to exceed ninety
(90) days after the date set forth in clause (i) of the first sentence of this
Section 9(c), the exercisability of the Rights in order to prepare and file such
registration statement and permit it to become effective. Upon any such
suspension, the Company shall issue a public announcement stating, and notify
the Rights Agent, that the exercisability of the Rights has been temporarily
suspended, as well as a public announcement and notification to the Rights Agent
at such time as the suspension is no longer in effect. The Company will also
take such action as may be appropriate under, or to ensure compliance with, the
securities or "blue sky" laws of the various states in connection with the
exercisability of the Rights. Notwithstanding any provision of this Rights
Agreement to the contrary, the Rights shall not be exercisable in any
jurisdiction, unless the requisite qualification in such jurisdiction shall have
been obtained, or an exemption therefrom shall be available, and until a
registration statement has been declared effective.

            (d) The Company covenants and agrees that it will take all such
action as may be necessary to ensure that all Preferred Shares (or other
securities of the Company) delivered upon exercise of Rights shall, at the time
of delivery of the certificates for such securities (subject to payment of the
Exercise Price), be duly and validly authorized and issued and fully paid and
nonassessable shares.

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

         10. Record Date. Each Person in whose name any certificate for a number
of one-thousandths of a Preferred Share (or other securities of the Company) is
issued upon the exercise Rights shall for all purposes be deemed to have become
the holder of record of Preferred Shares (or other securities of the Company)
represented thereby on, and such certificate shall be dated, the date upon which
the Rights Certificate evidencing such Rights was duly surrendered and payment
of the Total Exercise Price with respect to which the Rights have been exercised
(and any applicable transfer taxes) was made; provided, however, that if the
date of such surrender and payment is a date upon which the transfer books of
the Company are closed, such Person shall be deemed to have become the record
holder of such shares on, and such certificate shall be dated, the next
succeeding Business Day on which the transfer books of the Company are open.
Prior to the exercise of the

                                      -14-
<PAGE>   18

Rights evidenced thereby, the holder of a Rights Certificate shall not be
entitled to any rights of a holder of Preferred Shares (or other securities of
the Company) 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.

         11. Adjustment of Exercise Price, Number of Shares or Number of Rights.
The Exercise Price, the number and kind of shares or other property covered by
each Right and the number of Rights outstanding are subject to adjustment from
time to time as provided in this Section 11.

                (i) Anything in this Rights Agreement to the contrary
notwithstanding, in the event the Company shall at any time after the date of
this Rights Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine
the outstanding Preferred Shares (by reverse stock split or otherwise) into a
smaller number of Preferred Shares, or (D) issue any shares of its capital stock
in a reclassification of the Preferred Shares (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation), then, in each such event,
except as otherwise provided in this Section 11 and Section 7(e) hereof: (1) the
Exercise Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification shall be
adjusted so that the Exercise Price thereafter shall equal the result obtained
by dividing the Exercise Price in effect immediately prior to such time by a
fraction (the "ADJUSTMENT FRACTION"), the numerator of which shall be the total
number of Preferred Shares (or shares of capital stock issued in such
reclassification of the Preferred Shares) outstanding immediately following such
time and the denominator of which shall be the total number of Preferred Shares
outstanding immediately prior to such time; provided, however, that in no event
shall the consideration to be paid upon the exercise of one Right be less than
the aggregate par value of the shares of capital stock of the Company issuable
upon exercise of such Right; and (2) the number of one-thousandths of a
Preferred Share (or share of such other capital stock) issuable upon the
exercise of each Right shall equal the number of one-thousandths of a Preferred
Share (or share of such other capital stock) as was issuable upon exercise of a
Right immediately prior to the occurrence of the event described in clauses
(A)-(D) of this Section 11(a)(i), multiplied by the Adjustment Fraction;
provided, however, that, no such adjustment shall be made pursuant to this
Section 11(a)(i) to the extent that there shall have simultaneously occurred an
event described in clause (A), (B), (C) or (D) of Section 11(n) with a
proportionate adjustment being made thereunder. Each Common Share that shall
become outstanding after an adjustment has been made pursuant to this Section
11(a)(i) shall have associated with the number of Rights, exercisable at the
Exercise Price and for the number of one-thousandths of a Preferred Share (or
shares of such other capital stock) as one Common Share has associated with it
immediately following the adjustment made pursuant to this Section 11(a)(i).

                (ii) Subject to Section 24 of this Rights Agreement, in the
event a Triggering Event shall have occurred, then promptly following such
Triggering Event each holder of a Right, except as provided in Section 7(e)
hereof, shall thereafter have the right to receive for each Right, upon exercise
thereof in accordance with the terms of this Rights

                                      -15-
<PAGE>   19

Agreement and payment of the Total Exercise Price in effect immediately prior to
the occurrence of the Triggering Event, in lieu of a number of one-thousandths
of a Preferred Share, such number of Common Shares of the Company as shall equal
the result obtained by multiplying the Exercise Price in effect immediately
prior to the occurrence of the Triggering Event by the number of one-thousandths
of a Preferred Share for which a Right was exercisable (or would have been
exercisable if the Distribution Date had occurred) immediately prior to the
first occurrence of a Triggering Event, and dividing that product by 50% of the
Current Per Share Market Price for Common Shares on the date of occurrence of
the Triggering Event; provided, however, that the Exercise Price and the number
of Common Shares of the Company so receivable upon exercise of a Right shall be
subject to further adjustment as appropriate in accordance with Section 11(e)
hereof to reflect any events occurring in respect of the Common Shares of the
Company after the occurrence of the Triggering Event.

                (iii) In lieu of issuing Common Shares in accordance with
Section 11(a)(ii) hereof, the company may, if a majority of the Company's Board
of Directors determines that such action is necessary or appropriate and not
contrary to the interest of holders of Rights (and, in the event that the number
of Common Shares which are authorized by the Company's Certificate of
Incorporation but not outstanding or reserved for issuance for purposes other
than upon exercise of the Rights are not sufficient to permit the exercise in
full of the Rights, or if any necessary regulatory approval for such issuance
has not been obtained by the Company), the Company shall: (A) determine the
excess of (1) the value of the Common Shares issuable upon the exercise of a
Right (the "CURRENT VALUE") over (2) the Exercise Price (such excess, the
"SPREAD") and (B) with respect to each Right, make adequate provision to
substitute for such Common Shares, upon exercise of the Rights, (1) cash, (2) a
reduction in the Exercise Price, (3) other equity securities of the Company
(including, without limitation, shares or units of shares of any series of
preferred stock which a majority of the Company's Board of Directors has deemed
to have the same value as Common Shares (such shares or units of shares of
preferred stock are herein called "COMMON STOCK EQUIVALENTS")), except to the
extent that the Company has not obtained any necessary stockholder or regulatory
approval for such issuance, (4) debt securities of the Company, except to the
extent that the Company has not obtained any necessary stockholder or regulatory
approval for such issuance, (5) other assets or (6) any combination of the
foregoing, having an aggregate value equal to the Current Value, where such
aggregate value has been determined by a majority of the Company's Board of
Directors based upon the advice of a nationally recognized investment banking
firm selected by a majority of the Company's Board of Directors; provided,
however, if the Company shall not have made adequate provision to deliver value
pursuant to clause (B) above within thirty (30) days following the first
occurrence of a Triggering Event (the "SECTION 11(a)(II) TRIGGER DATE"), then
Company shall be obligated to deliver, upon the surrender for exercise of Right
and without requiring payment of the Exercise Price, Common Shares (to the
extent available), except to extent that the Company has not obtained any
necessary stockholder or regulatory approval for such issuance, and then, if
necessary, cash, which shares and/or cash have an aggregate value equal to the
Spread. If a majority of the Company's Board of Directors shall determine in
good faith that it is likely that sufficient additional Common Shares could be
authorized for issuance upon exercise in full of the Rights or that any
necessary regulatory approval for such issuance will be obtained, the thirty
(30) day period set forth above may be extended to the extent necessary, but not
more than ninety (90) days after the Section 11(a)(ii) Trigger Date, in order
that the Company may seek stockholder approval for the authorization of such
additional shares or take action to obtain such

                                      -16-
<PAGE>   20

regulatory approval (such period, as it may be extended, the "SUBSTITUTION
PERIOD"). To the extent that the Company determines that some action need be
taken pursuant to the first and/or second sentences of this Section 11(a)(iii),
the Company (x) shall provide, subject to Section 7(e) hereof, that such action
shall apply uniformly to all outstanding Rights and (y) may suspend the
exercisability of the Rights until the expiration of the Substitution Period in
order to seek any authorization of additional shares, to take any action to
obtain any required regulatory approval and/or to decide the appropriate form of
distribution t be made pursuant to such first sentence and to determine the
value thereof. In the event of any such suspension, the Company shall issue a
public announcement stating that the exercisability of the Rights has been
temporarily suspended, as well as a public announcement at such time as the
suspension is no longer in effect. For purposes of this Section 11(a)(iii), the
value of the Common Shares shall be the Current Per Share Market Price of the
Common Shares on the Section 11(a)(ii) Trigger Date and the value of any Common
Stock Equivalent shall be deemed to have the same value as the Common Shares on
such date.

            (b) In case the Company shall, at any time after the date of this
Rights Agreement, fix a record date for the issuance of rights, options or
warrants to all holders of Preferred Shares entitling such holders (for a period
expiring within forty-five (45) calendar days after such record date) to
subscribe for or purchase Preferred Shares or Equivalent Shares or securities
convertible into Preferred Shares or Equivalent Shares at a price per share (or
having a conversion price per share, if a security convertible into Preferred
Shares or Equivalent Shares) less than the then Current Per Share Market Price
of the Preferred Shares or Equivalent Shares on such record date, then, in each
such case, 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 and Equivalent Shares (if any) outstanding on such record date,
plus the number of Preferred Shares or Equivalent Shares, as the case may be,
which the aggregate offering price of the total number of Preferred Shares or
Equivalent Shares, as the case may be, to be offered or issued (and/or the
aggregate initial conversion price of the convertible securities to be offered
or issued) would purchase at such current market price, and the denominator of
which shall be the number of Preferred Shares and Equivalent Shares (if any)
outstanding on such record date, plus the number of additional Preferred Shares
or Equivalent Shares, as the case may be, to be offered for subscription or
purchase (or into which the convertible securities so to be offered are
initially convertible); provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. In case such subscription price may be paid in a
consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be as determined in good faith by a majority of the
Company's Board of Directors, whose determination shall be described in a
statement filed with the Rights Agent and shall be binding on the Rights Agent
and the holders of the Rights. Preferred Shares and Equivalent Shares owned by
or held for the account of the Company shall no be deemed outstanding for the
purpose of any such computation. Such adjustment shall be made successively
whenever such a record date is fixed, and in the event that such rights, options
or warrants are not so issued, the Exercise Price shall be adjusted to be the
Exercise Price which would then be in effect if such record date had not been
fixed.

                                      -17-
<PAGE>   21

            (c) In case the Company shall, at any time after the date of this
Rights Agreement, fix a record date for the making of a distribution to all
holders of the Preferred Shares or of any class or series of Equivalent Shares
(including any such distribution made in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation) of
evidences of indebtedness or assets (other than a regular quarterly cash
dividend, if any, or a dividend payable in Preferred Shares) or subscription
rights, options or warrants (excluding those referred to in Section 11(b)),
then, in each such case, 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
Current Per Share Market Price of a Preferred Share or an Equivalent Share on
such record date, less the fair market value per Preferred Share or Equivalent
Share (as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent) of the portion of the cash, assets or evidences of indebtedness so to be
distributed or of such subscription rights or warrants applicable to a Preferred
Share or Equivalent Share, as the case may be, and the denominator of which
shall be such Current Per Share Market Price of a Preferred Share or Equivalent
Share on such record date; provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. Such adjustments shall be made successively whenever such
a record date is fixed, and in the event that such distribution is not so made,
the Exercise Price shall be adjusted to be the Exercise Price which would have
been in effect if such record date had not been fixed.

            (d) Anything herein to the contrary notwithstanding, 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; provided, however,
that any adjustments which by reason of this Section 11(d) are not required to
be made shall be carried forward and taken into account in any subsequent
adjustment. All calculations under this Section 11 shall be made to the nearest
cent or to the nearest ten-thousandths of a Common Share or other share or one
hundred-thousandths of a Preferred Share, as the case may be. Notwithstanding
the first sentence of this Section 11(d), any adjustment required by this
Section 11 shall be made no later than the earlier of (i) three (3) years from
the date of the transaction which requires such adjustment or (ii) the
Expiration Date.

            (e) If as a result of an adjustment made pursuant to Section 11(a)
or 13(a) hereof, the holder of any Right thereafter exercised shall become
entitled to receive any shares of capital stock other than Preferred Shares,
thereafter the number of such other shares so receivable upon exercise of any
Right and, if required, the Exercise Price thereof, shall be subject to
adjustments from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the Preferred Shares contained in
Sections 11(a), 11(b), 11(c), 11(d), 11(g), 11(h), 11(i), 11(j), 11(k) and
11(l), 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.

            (f) 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-thousandths of a
Preferred Share purchasable from time to time hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

                                      -18-
<PAGE>   22

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

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

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

            (j) Before taking any action that would cause an adjustment reducing
the Exercise Price below the par or stated value, if any, of the number of
one-thousandths of a Preferred Share 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

                                      -19-
<PAGE>   23

validly and legally issue as fully paid and nonassessable shares such number of
one-thousandths of a Preferred Share at such adjusted Exercise Price.

            (k) In any case in which this Section 11 shall require that an
adjustment in the Exercise Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuing to the holder of any Right exercised after such record date of
the number of one-thousandths of a Preferred Share and other capital stock or
securities of the Company, if any, issuable upon such exercise over and above
the number of one-thousandths of a Preferred Share and other capital stock or
securities of the Company, if any, issuable upon such exercise on the basis of
the Exercise Price in effect prior to such adjustment; provided, however, that
the Company shall deliver to such holder a due bill or other appropriate
instrument evidencing such holder's right t receive such additional shares
(fractional or otherwise) upon the occurrence of the event requiring such
adjustment.

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

            (m) The Company covenants and agrees that, after the Distribution
Date, it will not, except as permitted by Sections 23, 24 or 27 hereof, take (or
permit to be taken) any action if at the time such action is taken it is
reasonably foreseeable that such actions will diminish substantially or
otherwise eliminate the benefits intended to be afforded by the Rights.

            (n) In the event the Company shall at any time after the date of
this Rights Agreement (A) declare a dividend on the Common Shares payable in
Common Shares, (B) subdivide the outstanding Common Shares, (C) combine the
outstanding Common Shares (by reverse stock split or otherwise) into a smaller
number of Common Shares, or (D) issue any shares of its capital stock in a
reclassification of the Common Shares (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
or surviving corporation), then, in each such event, except as otherwise
provided in this Section 11(a) and Section 7(e) hereof: (1) each Common Share
(or shares of capital stock issued in such reclassification of the Common
Shares) outstanding immediately following such time shall have associated with
it the number of Rights as were associated with one Common Share immediately
prior to the occurrence of the event described in clauses (A)-(D) above; (2) the
Exercise Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification shall be
adjusted so that the Exercise Price thereafter shall equal the result obtained
by multiplying the Exercise Price in effect immediately prior to such time by a
fraction, the numerator of which shall be the total number of Common Shares
outstanding immediately prior to the event described in clauses (A)-(D) above,
and the denominator of which shall be the total number of Common Shares
outstanding

                                      -20-
<PAGE>   24

immediately after such event; provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of such Right; and (3) the number of one-thousandths of a Preferred
Share (or shares of such other capital stock) issuable upon the exercise of each
Right outstanding after such event shall equal the number of one-thousandths of
a Preferred Share (or shares of such other capital stock) as were issuable with
respect to one Right immediately prior to such event. Each Common Share that
shall become outstanding after an adjustment has been made pursuant to this
Section 11(n) shall have associated with it the number of Rights, exercisable at
the Exercise Price and for the number of one-thousandths of a Preferred Share
(or shares of such other capital stock) as one Common Share has associated with
it immediately following the adjustment made pursuant to this Section 11(n). If
an event occurs which would require an adjustment under both this Section 11(n)
and Section 11(a)(ii) hereof, the adjustment provided for in this Section 11(n)
shall be in addition to, and shall be made prior to, any adjustment required
pursuant to Section 11(a(ii))hereof.

         12. Certificate of Adjusted Exercise Price or Number of Shares.
Whenever an adjustment is made as provided in Sections 11 and 13 hereof, the
Company shall promptly (a) prepare a certificate setting forth such adjustment
and a brief statement of the facts accounting for such adjustment, (b) file with
the Rights Agent and with each transfer agent for the Preferred Shares a copy of
such certificate and (c) mail a brief summary thereof to each holder of a Rights
Certificate in accordance with Section 26 hereof. Notwithstanding the foregoing
sentence, the failure of the Company to make such certification or give such
notice shall not affect the validity of such adjustment or the force or effect
of the requirement for such adjustment. The Right Agent shall be fully protected
in relying on any such certificate and on any adjustment contained therein and
shall not be deemed to have knowledge of such adjustment unless and until it
shall have received such certificate.

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

            (a) In the event that, following a Triggering Event, directly or
indirectly:

                (i) the Company shall consolidate with, or merge with and into,
any other Person (other than a wholly-owned Subsidiary of the Company in a
transaction the principal purpose of which is to change the state of
incorporation of the Company and which complies with Section 11(m), 11(n)
hereof);

                (ii) any Person shall consolidate with the Company, or merge
with and into the Company and the Company shall be the continuing or surviving
corporation of such consolidation or merger and, in connection with such merger,
all or part of the Common Shares shall be changed into or exchanged for stock or
other securities of any other person (or of the Company); or

                (iii) the Company shall sell or otherwise transfer (or one or
more of its Subsidiaries shall sell or otherwise transfer), in one or more
transactions, assets or earning power aggregating 50% or more of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person or Persons (other than the Company or one or more of its

                                      -21-
<PAGE>   25

wholly-owned Subsidiaries in one or more transactions, each of which
individually (and together) complies with Section 11(m) hereof).

         then, concurrent with and in each such case,

                    (1) each holder of a Right (except as provided in Section
7(e) hereof) shall thereafter have the right to receive, upon the exercise
thereof at a price equal to the Exercise Price applicable immediately prior to
the occurrence of the Section 13 Event in accordance with the terms of this
Rights Agreement, such number of validly authorized and issued, fully paid,
nonassessable and freely tradable Common Shares of the Principal Party (as
hereinafter defined), free of any liens, encumbrances, rights of first refusal
or other adverse claims, as shall be equal to the result obtained by dividing
such Exercise Price by 50% of the Current Per Share Market Price of the Common
Shares of such Principal Party on the date of consummation of such Section 13
Event, provided, however, that the Exercise Price and the number of Common
Shares of such Principal Party so receivable upon exercise of a Right shall be
subject to further adjustment as appropriate in accordance with Section 11(e)
hereof.

                    (2) such Principal Party shall thereafter be liable for, and
shall assume, by virtue of such Section 13 Event, all the obligations and duties
of the Company pursuant to this Rights Agreement;

                    (3) the term "Company shall thereafter be deemed to refer to
such Principal Party, it being specifically intended that the provisions of
Section 11 hereof shall apply only to such Principal Party following the first
occurrence of a Section 13 Event;

                    (4) such Principal Party shall take such steps (including,
but not limited to, the reservation of a sufficient number of it s Common
Shares) in connection with the consummation of any such transaction as may be
necessary to ensure that the provisions hereof shall thereafter be applicable,
as nearly as reasonably may be, in relation to its Common Shares thereafter
deliverable upon the exercise of the Rights; and

                    (5) upon the subsequent occurrence of any consolidation,
merger, sale or transfer of assets or other extraordinary transaction in respect
of such Principal Party, each holder of a Right shall thereupon be entitled to
receive, upon exercise of a Right and payment of the Exercise Price as provided
in this Section 13(a), such cash, shares, rights, warrants and other property
which such holder would have been entitled to receive had such holder, at the
time of such transaction, owned the Common Shares of the Principal Party
receivable upon the exercise of such Right pursuant to this Section 13(a), and
such Principal Party shall take such steps (including, but not limited to,
reservation of shares of stock) as may be necessary to permit the subsequent
exercise of the Rights in accordance with the terms hereof for such cash,
shares, rights, warrants and other property.

                    (6) for purposes hereof, the "earning power" of the Company
and its Subsidiaries shall be determined in good faith by the Company's Board of
Directors on the basis of the operating earnings of each business operated by
the Company and its Subsidiaries during the three fiscal years preceding the
date of such determination (or, in the case of any business not operated by the
Company or any Subsidiary during three full fiscal years

                                      -22-
<PAGE>   26

preceding such date, during the period such business was operated by the Company
or any Subsidiary).

            (b) For purposes of this Rights Agreement, the term "PRINCIPAL
PARTY" shall mean:

                (i) in the case of any transaction described in clause (i) or
(ii) of Section 13(a) hereof: (A) the Person that is the issuer of the
securities into which the Common Shares are converted in such merger or
consolidation, or, if there is more than one such issuer, the issuer the Common
Shares of which have the greatest aggregate market value of shares outstanding,
or (B) if no securities are so issued, (x) the Person that is the other party to
the merger, if such Person survives said merger, or, if there is more than one
such Person, the Person the Common Shares of which have the greatest aggregate
market value of shares outstanding or (y) if the Person that is the other party
to the merger does not survive the merger, the Person that does survive the
merger (including the Company if it survives) or (z) the Person resulting from
the consolidation; and

                (ii) in the case of any transaction described in clause (iii) of
Section 13(a) hereof, the Person that is the party receiving the greatest
portion of the assets or earning power transferred pursuant to such transaction
or transactions, or, if more than one Person that is a party to such transaction
or transactions receives the same portion of the assets or earning power so
transferred and each such portion would, were it not for the other equal
portions, constitute the greatest portion of the assets or earning power so
transferred, or if the Person receiving the greatest portion of the assets or
earning power cannot be determined, whichever of such Persons is the issuer of
Common Shares having the greatest aggregate market value of shares outstanding;

provided, however, that in any such case described in the foregoing clause
(b)(i) or (b)(ii), if the Common Shares of such Person are not at such time or
have not been continuously over the preceding 12-month period registered under
Section 12 of the Exchange Act, then (1) if such Person is a direct or indirect
Subsidiary of another Person the Common Shares of which are and have been so
registered, the term "Principal Party" shall refer to such other Person, or (2)
if such Person is a Subsidiary, directly or indirectly, of more than one Person,
the Common Shares of which are and have been so registered, the term "Principal
Party" shall refer to whichever of such Persons is the issuer of Common Shares
having the greatest aggregate market value of shares outstanding, or (3) if such
Person is owned, directly or indirectly, by a joint venture formed by two or
more Persons that are not owned, directly or indirectly by the same Person, the
rules set forth in clauses (1) and (2) above shall apply to each of the owners
having an interest in the venture as if the Person owned by the joint venture
was a Subsidiary of both or all of such joint venturers, and the Principal Party
in each such case shall bear the obligations set forth in this Section 13 in the
same ratio as its interest in such Person bears to the total of such interests.

            (c) The Company shall not consummate any Section 13 Event unless the
Principal Party shall have a sufficient number of authorized Common Shares that
have not been issued or reserved for issuance to permit the exercise in full of
the Rights in accordance with this Section 13 and unless prior thereto the
Company and such issuer shall have executed and delivered to the Rights Agent a
supplemental agreement confirming that such Principal Party

                                      -23-
<PAGE>   27

shall, upon consummation of such Section 13 Event, assume this Rights Agreement
in accordance with Sections 13(a) and 13(b) hereof, that all rights of first
refusal or preemptive rights in respect of the issuance of Common Shares of such
Principal Party upon exercise of outstanding Rights have been waived, that there
are no rights, warrants, instruments or securities outstanding or any agreements
or arrangements which, as a result of the consummation of such transaction,
would eliminate or substantially diminish the benefits intended to be afforded
by the Rights and that such transaction shall not result in a default by such
Principal Party under this Rights Agreement, and further providing that, as soon
as practicable after the date of such Section 13 Event, such Principal Party
will:

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

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

                (iii) deliver to holders of the Rights historical financial
statement for such Principal Party which comply in all respects with the
requirements for registration on Form 10 (or any successor form) under the
Exchange Act.

         In the event that at any time after the occurrence of a Triggering
Event some or all of the Rights shall not have been exercised at the time of a
transaction described in this Section 13, the Rights which have not theretofore
been exercised shall thereafter be exercisable in the manner described in
Section 13(a) (without taking into account any prior adjustments required by
Section 11(a)(ii)).

            (d) In case the "Principal Party" for purposes of Section 13(b)
hereof has provision in any of its authorized securities or in its certificate
of incorporation or by-laws or other instrument governing its corporate affairs,
which provision would have the effect of (i) causing such Principal Party to
issue (other than to holders of Rights pursuant to Section 13 hereof), in
connection with, or as a consequence of, the consummation of a Section 13 Event,
Common Shares or Equivalent Shares of such Principal Party at less than the then
Current Per Share Market Price thereof or securities exercisable for, or
convertible into, Common Shares or Equivalent Shares of such Principal Party at
less than such then Current Per Share Market Price, or (ii) providing for any
special payment, tax or similar provision in connection with the issuance of the
Common Shares of such Principal Party pursuant to the provisions of Section 13
hereof, then, in such event, the Company hereby agrees with each holder of
Rights that it shall not consummate any such transaction unless prior thereto
the Company and such Principal Party shall have executed and delivered to the
Rights Agents a supplemental agreement providing that the provision in question
of such Principal Party shall have been canceled, waived or amended,

                                      -24-
<PAGE>   28

or that the authorized securities shall be redeemed, so that the applicable
provision will have no effect in connection with or as a consequence of, the
consummation of the proposed transaction.

            (e) The Company covenants and agrees that it shall not, at any time
after the Distribution Date, effect or permit to occur any Section 13 Event, if
(i) at the time or immediately after such Section 13 Event there are any rights,
warrants or other instruments or securities outstanding or agreements in effect
which would substantially diminish or otherwise eliminate the benefits intended
to be afforded by the Rights, (ii) prior to, simultaneously with or immediately
after such Section 13 Event, the stockholders of the Person who constitutes, or
would constitute, the "Principal Party" for purposes of Section 13(b) hereof
shall have received a distribution of Rights previously owned by such Person or
any of its Affiliates or Associates or (iii) the form or nature of organization
of the Principal Party would preclude or limit the exercisability of the Rights.

            (f) The provisions of this Section 13 shall similarly apply to
successive mergers or consolidations or sales or other transfers.

         14. Fractional Rights and Fractional Shares.

            (a) The Company shall not be required to issue fractions of Rights
or to distribute Rights Certificates which evidence fractional Rights. In lieu
of such fractional Rights, there shall be paid to the registered holders of the
Rights Certificates with regard to which such fractional Rights would otherwise
be issuable, an amount in cash equal to the same fraction of the current market
value of a whole Right. For the purposes of this Section 14(a), the current
market value of a whole Right shall be the closing price of the Rights for the
Trading Day immediately prior to the date on which such fractional Rights would
have been otherwise issuable, as determined pursuant to the second sentence of
Section 1(j) hereof.

            (b) The Company shall not be required to issue fractions of
Preferred Shares (other than fractions that are integral multiples of one
one-thousandth of a Preferred Share) upon exercise of the Rights or to
distribute certificates which evidence fractional Preferred Shares (other than
fractions that are integral multiples of one one-thousandth of a Preferred
Share). Interests in fractions of Preferred Shares in integral multiples of one
one-thousandth of a Preferred Share may, at the election of the Company, be
evidenced by depositary receipts, pursuant to an appropriate agreement between
the Company and a depositary selected by it; provided, that such agreement shall
provide that the holders of such depositary receipts shall have all the rights,
privileges and preferences to which they are entitled as beneficial owners of
the Preferred Shares represented by such depositary receipts. In lieu of
fractional Preferred Shares that are not integral multiples of one
one-thousandth of a Preferred Share, the Company shall pay to the registered
holders of 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 a Preferred Share. For purposes of this Section 14(b), the current
market value of a Preferred Share shall be one thousand times the closing price
of a Common Share (as determined pursuant to the second sentence of Section 1(j)
hereof) for the Trading Day immediately prior to the date of such exercise.

                                      -25-
<PAGE>   29

            (c) The Company shall not be required to issue fractions of Common
Shares or to distribute certificates which evidence fractional Common Shares
upon the exercise or exchange of Rights. In lieu of such fractional Common
Shares, the Company shall 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 a Common Share. For purposes
of this Section 14(c), the current market value of a Common Shares shall be the
closing price of a Common Share (as determined pursuant to the second sentence
of Section 1(j) hereof for the Trading Day immediately prior to the date of such
exercise.

            (d) The holder of a Right by the acceptance of the Right expressly
waives his or her right to receive any fractional Rights or any fractional
shares (other than fractions that are integral multiple of one one-thousandth of
a Preferred Share) upon exercise of a Right.

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

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

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

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

            (c) subject to Sections 6(a) and 7(f) hereof, the Company and the
Rights Agent may deem and treat the person in whose name the Rights Certificates
(or, prior tot he Distribution Date, the associated Common Shares certificate)
is registered as the absolute owner thereof and of the Rights evidenced thereby
(notwithstanding any notations of ownership or writing on the Rights
Certificates or the associated Common Shares certificate made by anyone other
than the Company or the Rights Agent) for all purposes whatsoever, and neither
the Company nor the Rights Agent shall be affected by any notice to the
contrary.

                                      -26-
<PAGE>   30

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

         18. Concerning the Rights Agent.

            (a) The Company agrees to pay to the Rights Agent reasonable
compensation for all services rendered by it hereunder and, from time to time,
on demand of the Rights Agent, its reasonable expenses and counsel fees and
other disbursements incurred in the administration and execution of this Rights
Agreement and the exercise and performance of its duties hereunder. The Company
also agrees to indemnify the Rights Agent for, and to hold it harmless against,
any loss, liability or expense, incurred without gross negligence, bad faith or
willful misconduct on the part of the Rights Agent, for anything done or omitted
by the Rights Agent in connection with the acceptance and administration of this
Rights Agreement, including the costs and expenses of defending against any
claim of liability in the premises. In no event will the Rights Agent be liable
for special, indirect, incidental or consequential loss or damage of any kind
whatsoever, even if the Rights Agent has been advised of the possibility of such
loss or damage.

            (b) The Rights Agent shall be protected and shall incur no liability
for, or in respect of any action taken, suffered or omitted by it in connection
with, its administration of this Rights Agreement in reliance upon any Rights
Certificate or certificate for the Preferred Shares or Common Shares or for
other securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, direction, consent,
certificate, statement or other paper or document reasonably believe by it to be
genuine and to be signed, executed and, where necessary, verified or
acknowledged by the proper Person or Persons, or otherwise upon the advice of
counsel as set forth in Section 20 hereof.

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

            (a) Any corporation into which the Rights Agent or any successor
Rights Agent may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which the Rights Agent
or any successor Rights Agents shall be a party, or any corporation succeeding
to the corporate trust business of the Rights Agent or any successor Rights
Agent, shall be the successor to the Rights Agent under this Rights Agreement
without the execution or filing of any paper or any further act on the part of
any of the parties hereto; provided, however, that such corporation would be
eligible for appointment as a successor Rights Agent under the provisions of
Section 21 hereof. In case at the time such successor Rights Agent shall succeed
to the agency created by this Rights Agreement, any of the

                                      -27-
<PAGE>   31

Rights Certificates shall have countersigned but not delivered, any such
successor Rights Agent may adopt the countersignature of the predecessor Rights
Agent and deliver such Rights Certificates so countersigned; and in case at that
time any of the Rights Certificates shall not have been countersigned, any
successor Rights Agent may countersign such Rights Certificates either in the
name of the predecessor Rights Agent or in the name of the successor Rights
Agent; and in all such cases such Rights Certificates shall have the full force
provided in the Rights Certificates and in this Rights Agreement.

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

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

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

            (b) Whenever in the performance of its duties under this Rights
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including, without limitation, the identity of any Acquiring Person and
the determination of Current Per Share Market Price) be proved or established by
the Company prior to taking or suffering any actions hereunder, such fact or
matter (unless other evidence in respect thereof be herein specifically
prescribed) may be deemed to be conclusively proved and established by a
certificate signed by any one of the Chairman of the Board, the Chief Executive
Officer, the President, any Vice President, the Chief Financial Officer, the
Secretary or any Assistant Secretary of the Company and delivered to the Rights
Agent; and such certification shall be full authorization to the Rights Agent
for any action taken or suffered in good faith by it under the provisions of
this Rights Agreement in reliance upon such certificate.

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

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

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

                                      -28-
<PAGE>   32

hereby by the Rights Agent) or in respect of the validity or execution of any
Rights Certificate (except its countersignature thereof); nor shall it be
responsible for any breach by the Company of any covenant or condition contained
in this Rights Agreement or in any Rights Certificate; nor shall it be
responsible for any change in the exercisability of the Rights or any adjustment
in the terms of the Rights (including the manner, method or amount thereof)
provided for in Sections 3, 11, 13, 23 or 24, or the ascertaining of the
existence of facts that would require any such change or adjustment (except with
respect to the exercise of Rights evidenced by Rights Certificates after receipt
by the Rights Agent of a certificate furnished pursuant to Section 12 describing
such change or adjustment); nor shall it by any act hereunder be deemed to make
any representation or warranty as to the authorization or reservation of any
Preferred Shares to be issued pursuant to this Rights Agreement or any Rights
Certificate or as to whether any Preferred Shares will, when issued, be validly
authorized and issued, fully paid and nonassessable.

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

            (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
one of the Chairman of the Board, the Chief Executive Officer, the President,
any Vice President, the Chief Financial Officer, the Secretary or any Assistant
Secretary of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and it shall not be liable for any
action taken or suffered by it in good faith in accordance with instructions of
any such officer or for any delay in acting while waiting for those
instructions. Any application by the Rights Agent for written instructions from
the Company may, at the option of the Rights Agent, set forth in writing any
action proposed to be taken or omitted by the Rights Agent under this Rights
Agreement and the date on and/or after which such action shall be taken by, or
omission of, the Rights Agent in accordance with a proposal included in any such
application on or after the date specified in such application (which date shall
not be less than five (5) Business Days after the date any officer of the
Company actually receives such application, unless any such officer shall have
consented in writing to an earlier date) unless, prior to taking any such action
(or the effective date in the case of an omission), the Rights Agent shall have
received written instructions in response to such application specifying the
action to be taken or omitted.

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

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

                                      -29-
<PAGE>   33

such act, default, neglect or misconduct, provided reasonable care was exercised
in the selection and continued employment thereof.

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

            (k) If, with respect to any Rights Certificate surrendered to the
Rights Agent for exercise or transfer, the certificate attached to the form of
assignment or form of election to purchase, as the case may be, has either not
been completed or indicates an affirmative response to clause 1 and/or 2
thereof, the Rights Agent shall not take any further action with respect to such
requested exercise or transfer without first consulting with the Company.

         21. Change of Rights Agent. The Rights Agent or any successor Rights
Agent may resign and be discharged from its duties under this Rights Agreement
upon thirty (30) days' notice in writing mailed to the Company and to each
transfer agent of the Preferred Shares and the Common Shares by registered or
certified mail, and to the holders of the Rights Certificates by first-class
mail. If the Rights Agent shall resign or be removed or shall otherwise become
incapable of acting, the Company shall appoint a successor to the Rights Agent.
If the Company shall fail to make such appointment within a period of thirty
(30) days after giving notice of such removal or after it has been notified in
writing of such resignation or incapacity by the resigning or incapacitated
Rights Agent or by the holder of a Rights Certificate (who shall, with such
notice, submit his or her Rights Certificate for inspection by the Company),
then the registered holder of any Rights Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent. Any successor
Rights Agent, whether appointed by the Company or by such a court, shall be a
corporation organized and doing business under the laws of the United States or
of any state of the United States, in good standing, which is authorized under
such laws to exercise corporate trust or stockholder services powers and is
subject to supervision or examination by federal or state authority and which
has at the time of its appointment as Rights Agent a combined capital and
surplus of at least $50 million. After appointment, the successor Rights Agent
shall be vested with the same powers, rights, duties and responsibilities as if
it had been originally named as Rights Agent without further act or deed; but
the predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Preferred Shares and the Common Shares, and mail a notice thereof in writing
to the registered holders of the Rights Certificates. Failure to give any notice
provided for in this Section 21, however, or any defect therein, shall not
affect the legality or validity of the resignation or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

         22. Issuance of New Rights Certificates. Notwithstanding any of the
provisions of this Rights Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Rights Certificates evidencing Rights in
such form as may be approved by its Board of

                                      -30-
<PAGE>   34

Directors to reflect any adjustment or change in the Exercise Price and the
number or kind or class of shares or other securities or property purchasable
under the Rights Certificates made in accordance with the provisions of this
Rights Agreement. In addition, in connection with the issuance or sale of Common
Shares following the Distribution Date and prior to the redemption or expiration
of the Rights, the Company (a) shall, with respect to Common Shares so issued or
sold pursuant to the exercise of stock options or under any employee plan or
arrangement or upon the exercise, conversion or exchange of other securities of
the Company outstanding at the date hereof or upon the exercise, conversion or
exchange of securities hereinafter issued by the Company and (b) may, in any
other case, if deemed necessary or appropriate by the Board of Directors of the
Company, issue Rights Certificates representing the appropriate number of Rights
in connection with such issuance or sale; provided, however, that (i) no such
Rights Certificate shall be issued and this sentence shall be null and void ab
initio if, and to the extent that, such issuance or this sentence would create a
significant risk of or result in material adverse tax consequences to the
Company or the Person to whom such Rights Certificate would be issued or would
create a significant risk or result in such options' or employee plans' or
arrangements' failing to qualify for otherwise available special tax treatment
and (ii) no such Rights Certificate shall be issued if, and to the extent that,
appropriate adjustment shall otherwise have been made in lieu of the issuance
thereof.

         23. Redemption.

            (a) The Company may, at its option and with the approval of the
Board of Directors, at any time prior to the occurrence of a Triggering Event,
redeem all but not less than all the then outstanding Rights at a redemption
price of $0.01 per Right, appropriately adjusted to reflect any stock split,
stock dividend or similar transaction occurring after the date hereof (such
redemption price being herein referred to as the "REDEMPTION PRICE") and the
Company may, at its option, pay the Redemption Price either in Common Shares
(based on the Current Per Share Market Price thereof at the time of redemption)
or cash. Such redemption of the Rights by the Company may be made effective at
such time, on such date on which the Board of Directors elects to make the
redemption effective shall be referred to as the "REDEMPTION DATE".

            (b) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights, evidence of which shall have been
filed with the Rights Agent, and without any further action and without any
notice, the right to exercise the Rights will terminate and the only right
thereafter of the holders of Rights shall be to receive the Redemption Price.
The Company shall promptly give public notice of any such redemption; provided,
however, that the failure to give or any defect in, any such notice shall not
affect the validity of such redemption. Within ten (10) days after the action of
the Board of Directors ordering the redemption of the Rights, the Company shall
give notice of such redemption to the Rights Agent and the holders of the then
outstanding Rights by mailing such notice to all such holders at their last
addresses as they appear upon the registry books of the Rights Agent or, prior
to the Distribution Date, on the registry books of the transfer agent for the
Common Shares. Any notice which is mailed in the manner herein provided shall be
deemed given, whether or not the holder receives the notice. Each such notice of
redemption will state the method by which the payment of the Redemption Price
will be made. Neither the Company nor any of its Affiliates or Associates may
redeem, acquire or purchase for value any Rights at any time in any manner

                                      -31-
<PAGE>   35

other than that specifically set forth in this Section 23 or in Section 24
hereof and other than in connection with the purchase of Common Shares prior to
the Distribution Date.

         24. Exchange.

            (a) Subject to applicable laws, rules and regulations, and subject
to subsection 24(c) below, the Company may, at its option, by action of the
Board of Directors, at any time after the occurrence of a Triggering Event,
exchange all or put of the then outstanding and exercisable Rights (which shall
not include Rights that have become void pursuant to the provisions of Section
7(e) hereof) for Common Shares at an exchange ratio of one Common Share per
Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (such exchange ratio being
hereinafter referred to as the "EXCHANGE RATIO"). Notwithstanding the foregoing,
the Board of Directors shall not be empowered to effect such exchange at any
time after any Person (other than the Company, any Subsidiary of the Company,
any employee benefit plan of the Company or any such Subsidiary, or any entity
holding Common Shares for or pursuant to the terms of any such plan), together
with all Affiliates and Associates of such Person, becomes the Beneficial Owner
of 50% or more of the Common Shares then outstanding.

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

            (c) In the event that there shall not be sufficient Common Shares
issued but not outstanding or authorized but unissued to permit any exchange of
Rights as contemplated in accordance with Section 24(a), the Company shall
either take such action as may be necessary to authorize additional Common
Shares for issuance upon exchange of the Rights or alternatively, at the option
of a majority of the Board of Directors, with respect to each Right (i) pay cash
in an amount equal to the Current Value (as hereinafter defined), in lieu of
issuing Common Shares in exchange therefor, or (ii) issue debt or equity
securities or a combination thereof, having a value equal to the Current Value,
in lieu of issuing Common Shares in exchange for each such Right, where the
value of such securities shall be determined by a nationally recognized
investment banking firm selected by majority vote of the Board of Directors, or
(iii) deliver any combination of cash, property, Common Shares and/or other
securities having a value equal to the Current Value in exchange for each Right.
For purposes of this Section 24(c) only, the Current Value

                                      -32-
<PAGE>   36

shall mean the product of the Current Per Share Market Price of Common Shares on
the date of the occurrence of the event described above in subparagraph (a),
multiplied by the number of Common Shares for which the Right otherwise would be
exchangeable if there were sufficient shares available. To the extent that the
Company determines that some action need be taken pursuant to clauses (i), (ii)
or (iii) of this Section 24(c), the Board of Directors may temporarily suspend
the exercisability of the Rights for a period of up to sixty (60) days following
the date on which the event described in Section 24(a) shall have occurred, in
order to seek any authorization of additional Common Shares and/or to decide the
appropriate form of distribution to be made pursuant to the above provision and
to determine the value thereof. In the event of any such suspension, the Company
shall issue a public announcement stating that the exercisability of the Rights
has been temporarily suspended.

            (d) The Company shall not be required to issue fractions of Common
Shares or to distribute certificates which evidence fractional Common Shares. In
lieu of such fractional Common Shares, there shall be paid to the registered
holders of the Rights Certificates with regard to which such fractional Common
Shares would otherwise be issuable, an amount in cash equal to the same fraction
of the current market value of a whole Common Share (as determined pursuant to
the second sentence of Section 1(j) hereof).

            (e) The Company may, at its option, by majority vote of the Board of
Directors, at any time before any Person has become an Acquiring Person,
exchange all or part of the then outstanding Rights for rights of substantially
equivalent value, as determined reasonably and with good faith by the Board of
Directors, based upon the advice of one or more nationally recognized investment
banking firms.

            (f) Immediately upon the action of the Board of Directors ordering
the exchange of any Rights pursuant to subsection 24(e) of this Section 24 and
without any further action and without any notice, the right to exercise such
Rights shall terminate and the only right thereafter of a holder of such Rights
shall be to receive that number of rights in exchange therefor as has been
determined by the Board of Directors in accordance with subsection 24(c) above.
The Company shall give public notice of any such exchange; provided, however,
that the failure to give, or any defect in, such notice shall not affect the
validity of such exchange. The Company shall mail a notice of any such exchange
to all of the holders of such Rights at their last addresses as they appear upon
the registry books of the transfer agent for the Common Shares of the Company.
Any notice which is mailed in the manner herein provided shall be deemed given,
whether or not the holder receives the notice. Each such notice of exchange will
state the method by which the exchange of the Rights will be effected.

         25. Notice of Certain Events.

            (a) In case the Company shall propose to effect or permit to occur
any Triggering Event or Section 13 Event, the Company shall give notice thereof
to each holder of Rights in accordance with Section 26 hereof at least twenty
(20) days prior to occurrence of such Triggering Event or such Section 13 Event.

            (b) In case any Triggering Event or Section 13 Event shall occur,
then, in any such case, the Company shall as soon as practicable thereafter give
to each holder of a Rights

                                      -33-
<PAGE>   37

Certificate, in accordance with Section 26 hereof, a notice of the occurrence of
such event, which shall specify the event and the consequences of the event to
holders of Rights under Sections 11(a)(ii) and 13 hereof.

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

shall be sufficiently given or made if sent by first-class mail, postage
prepaid, addressed to such holder at the address of such holder as shown on the

         27. Supplements and Amendments. Prior to the occurrence of a Triggering
Event, the Company may supplement or amend this Rights Agreement in any respect
without the approval of any holders of Rights, and the Rights Agent shall, if
the Company so directs, execute such supplement or amendment. From and after the
occurrence of a Triggering Event, the Company and the Rights Agent may from time
to time supplement or amend this Rights Agreement without the approval of any
holders of Rights in order to (i) cure any ambiguity, (ii) correct or supplement
any provision contained herein which may be defective or inconsistent with any
other provisions herein, (iii) shorten or lengthen any time period hereunder, or
(iv) to change or supplement the provisions hereunder in any manner that the
Company may deem necessary or

                                      -34-
<PAGE>   38

desirable and that shall not adversely affect the interests of the holders of
Rights (other than an Acquiring Person or an Affiliate or Associate of an
Acquiring Person); provided, this Rights Agreement may not be supplemented or
amended to lengthen, pursuant to clause (iii) of this sentence, (A) a time
period relating to when the Rights may be redeemed at such time as the Rights
were not then redeemable or (B) any other time period unless such lengthening is
for the purpose of protecting, enhancing or clarifying the rights of, and/or the
benefits to, the holders of Rights (other than Acquiring Person or an Affiliate
or Associate of an Acquiring Person). Upon the delivery of a certificate from an
appropriate officer of the Company that states that the proposed supplement or
amendment is in compliance with the terms of this Section 27, the Rights Agent
shall execute such supplement or amendment. Prior to the Distribution Date, the
interests of the holders of Rights shall be deemed coincident with the interests
of the holders of Common Shares.

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

         29. Determinations and Actions by the Board of Directors, etc. For all
purposes of this Rights Agreement, any calculation of the number of Common
Shares outstanding at any particular time, including for purposes of determining
the particular percentage of such outstanding Common 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) of the General Rules and Regulations under the Exchange Act.
The Board of Directors of the Company shall have the exclusive power and
authority to administer this Rights Agreement and to exercise all rights and
powers specifically granted to the Board, or the Company, or as may be necessary
or advisable in the administration of this Rights Agreement, including, without
limitation, the right and power to (i) interpret the provisions of this Rights
Agreement and (ii) make all determinations deemed necessary or advisable for the
administration of this Rights Agreement (including a determination to redeem or
not redeem the Rights or to amend the Rights Agreement). All such actions,
calculations, interpretations and determinations (including. for purposes of
clause (y) below, all omissions with respect to the foregoing) which are done or
made by the Board in good faith, shall (x) be final, conclusive and binding on
the Company, the Rights Agent, the holders of the Rights Certificates; and all
other parties and (y) not subject the Board to any liability to the holders of
the Rights.

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

         31. Severability. If any term, provision, covenant or restriction of
this Rights Agreement is held by a court of competent jurisdiction or other
authority to be invalid, void or unenforceable, the remainder of the terms,
provisions, covenants and restrictions of this Rights Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
provided, however, that notwithstanding anything in this Rights Agreement to the

                                      -35-
<PAGE>   39

contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing the
invalid language from this Rights Agreement would adversely affect the purpose
or effect of this Rights Agreement, the right of redemption set forth in Section
23 hereof shall be reinstated and shall not expire until the Close of Business
on the tenth day following the date of such determination by the Board of
Directors.

         32. Governing Law. This Rights Agreement and each Right 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 to
be made and performed entirely within such State.

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

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

                               OF CYBERONICS, INC.

The undersigned, Robert P. Cummins and Reese S. Terry, Jr., do hereby certify:

1. That they are the duly elected and acting Chief Executive Officer and
Secretary, respectively, of Cyberonics, Inc., a Delaware corporation (the
"CORPORATION").

2. That pursuant to the authority conferred upon the Board of Directors by the
Restated Certificate of Incorporation of the said Corporation, the said Board of
Directors on January 29, 1997 adopted the following resolution creating a series
of 50,000 shares of Preferred Stock designated as Series A Participating
Preferred Stock:

"RESOLVED, that pursuant to the authority vested in the Board of Directors of
the corporation by the Restated Certificate of Incorporation, the Board of
Directors does hereby provide for the issue of a series of Preferred Stock of
the Corporation and does hereby fix and herein state and express the
designations, powers, preferences and relative and other special rights and the
qualifications, limitations and restrictions of such series of Preferred Stock
as follows:

                 Designation and Amount. The shares of such series shall be
                 designated as "SERIES A PARTICIPATING PREFERRED STOCK." The
                 Series A Participating Preferred Stock shall have a par value
                 of $0.01 per share, and the number of shares constituting such
                 series shall be 50,000.

                 Proportional Adjustment. In the event the Corporation shall at
                 any time after the issuance of any share or shares of Series A
                 Participating Preferred Stock (i) declare any dividend on
                 Common Stock of the Corporation ("COMMON STOCK") payable in
                 shares of Common Stock, (ii) subdivide the outstanding Common
                 Stock or (iii) combine the outstanding Common Stock into a
                 smaller number of shares, then in each such case the
                 Corporation shall simultaneously effect a proportional
                 adjustment to the number of outstanding shares of Series A
                 Participating Preferred Stock.

             Dividends and Distributions.

                 Subject to the prior and superior right of the holders of any
                 shares of any series of Preferred Stock ranking prior and
                 superior to the shares of Series A Participating Preferred
                 Stock with respect to dividends, the holders of shares of
                 Series A Participating Preferred Stock shall be entitled to
                 receive when, as and if declared by the Board of Directors out
                 of funds legally available for that purpose, quarterly
                 dividends payable in cash on the last day of January, April,
                 July and October in each

                                      -38-

                 year (each such date being referred to herein as a "QUARTERLY
                 DIVIDEND PAYMENT DATE"), commencing on the first Quarterly
                 Dividend Payment Date after the first issuance of a share or
                 fraction of a share of Series A Participating Preferred Stock,
                 in an amount per share (rounded to the nearest cent) equal to
                 1,000 times the aggregate per share amount of all cash
                 dividends, and 1,000 times the aggregate per share amount
                 (payable in kind) of all non-cash dividends or other
                 distributions other (except as provided in Section 2 hereof)
                 than a dividend payable in shares of Common Stock or a
                 subdivision of the outstanding shares of Common Stock (by
                 reclassification or otherwise), declared on the Common Stock
                 since the immediately preceding Quarterly Dividend Payment
                 Date, or, with respect to the first Quarterly Dividend Payment
                 Date, since the first issuance of any share or fraction of a
                 share of Series A Participating Preferred Stock.

                 The Corporation shall declare a dividend or distribution on the
                 Series A Participating Preferred Stock as provided in paragraph
                 (a) above immediately after it declares a dividend or
                 distribution on the Common Stock (other than a dividend payable
                 in shares of Common Stock).

                 Dividends shall begin to accrue on outstanding shares of Series
                 A Participating Preferred Stock from the Quarterly Dividend
                 Payment Date next preceding the date of issue of such shares of
                 Series A Participating Preferred Stock, unless the date of
                 issue of such shares is prior to the record date for the first
                 Quarterly Dividend Payment Date, in which case dividends on
                 such shares shall begin to accrue from the date of issue of
                 such shares, or unless the date of issue is a Quarterly
                 Dividend Payment Date or is a date after the record date for
                 the determination of holders of shares of Series A
                 Participating Preferred Stock entitled to receive a quarterly
                 dividend and before such Quarterly Dividend Payment Date, in
                 either of which events such dividends shall begin to accrue
                 from such Quarterly Dividend Payment Date. Accrued but unpaid
                 dividends shall not bear interest. Dividends paid on the shares
                 of Series A Participating Preferred Stock in an amount less
                 than the total amount of such dividends at the time accrued and
                 payable on such shares shall be allocated pro rata on a
                 share-by-share basis among all such shares at the time
                 outstanding. The Board of Directors may fix a record date for
                 the determination of holders of shares of Series A
                 Participating Preferred Stock entitled to receive payment of a
                 dividend or distribution declared thereon, which record date
                 shall be no more than 30 days prior to the date fixed for the
                 payment thereof.

                 Voting Rights.  The holders of shares of Series A Participating
                 Preferred Stock shall have the following voting rights:

                 (i) Each share of Series A Participating Preferred Stock shall
                 entitle the holder thereof to 1,000 votes on all matters
                 submitted to a vote of the stockholders of the Corporation.

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

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

              Certain Restrictions.

                 The Corporation shall not declare any dividend on, make any
                 distribution on, or redeem or purchase or otherwise acquire for
                 consideration any shares of Common Stock after the first
                 issuance of a share or fraction of a share of Series A
                 Participating Preferred Stock unless concurrently therewith it
                 shall declare a dividend on the Series A Participating
                 Preferred Stock as required by Section 3 hereof.

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

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

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

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

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

                 The Corporation shall not permit any subsidiary of the
                 Corporation to purchase or otherwise acquire for consideration
                 any shares of stock of the Corporation unless the Corporation
                 could, under paragraph (a) of this Section 5, purchase or
                 otherwise acquire such shares at such time and in such manner.

                 Reacquired Shares. Any shares of Series A Participating
                 Preferred Stock purchased or otherwise acquired by the
                 Corporation in any manner whatsoever shall be retired and
                 canceled promptly after the acquisition thereof. All such
                 shares shall upon their cancellation become authorized but
                 unissued shares of Preferred Stock and may be reissued as part
                 of a new series of Preferred Stock to be created by resolution
                 or resolutions of the Board of Directors, subject to the
                 conditions and restrictions on issuance set forth herein and,
                 in the Restated Certificate of Incorporation, as then amended.

                 Liquidation, Dissolution or Winding Up. Upon any liquidation,
                 dissolution or winding up of the Corporation, the holders of
                 shares of Series A Participating Preferred Stock shall be
                 entitled to receive an aggregate amount per share equal to 1000
                 times the aggregate amount to be distributed per share to
                 holders of shares of Common Stock plus an amount equal to any
                 accrued and unpaid dividends on such shares of Series A
                 Participating Preferred Stock.

                 Consolidation, Merger, etc. In case the Corporation shall enter
                 into any consolidation, merger, combination or other
                 transaction in which the shares of Common Stock are exchanged
                 for or changed into other stock or securities, cash and/or any
                 other property, then in any such case the shares of Series A
                 Participating Preferred Stock shall at the same time be
                 similarly exchanged or changed in an amount per share equal to
                 1,000 times the aggregate amount of stock, securities, cash
                 and/or any other property (payable in kind), as the case may
                 be, into which or for which each share of Common Stock is
                 changed or exchanged.

                 No Redemption. The shares of Series A Participating Preferred
                 Stock shall not be redeemable.

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

                 Amendment. The Restated Certificate of Incorporation of the
                 Corporation shall not be further amended in any manner which
                 would materially alter or change the powers, preference or
                 special rights of the Series A Participating Preferred Stock so
                 as to affect them adversely without the affirmative vote of the
                 holders of a majority of the outstanding shares of Series A
                 Participating Preferred Stock, voting separately as a class.

                 Fractional Shares. Series A Participating Preferred Stock may
                 be issued in fractions of a share which shall entitle the
                 holder, in proportion to such holder's fractional shares,

                  distributions and to have the benefit of all other rights of
                  holders of Series A Participating Preferred Stock.

RESOLVED FURTHER, that the President or any Vice President and the Secretary or
any Assistant Secretary of this corporation be, and they hereby are, authorized

provisions of Delaware law and to take such actions as they may deem necessary

Transfer of Rights                      right (a "Right") for each share of Cyberonics, Inc.
Rights Certificate                      common stock, par value $0.01 per share (the "Common Shares").
                                        Prior to the Distribution Date (as defined below) the Rights
                                        will be evidenced by and trade with the certificates for the Common

                                        will mail Rights certificates to the Company's stockholders and the
                                        Rights will become transferable apart from the Common Shares.

Distribution Date                       Rights will separate from the Common Shares and become
                                        exercisable following (a) the tenth day after a person or group

                                        after a person or group announces a tender or exchange offer, the
                                        consummation of which would result in ownership by a person or group of
                                        15% or more of the Company's Common Shares (each a "Distribution Date").

Common Shares:                          more of the Company's Common Shares, then each Right
                                        (other than Rights owned by an Acquiring Person or its
                                        affiliates) will entitle the holder thereof to
                                        purchase, for the Exercise Price, a number of shares of
                                        the Company's Common Shares having a then current market

                                Price, a number of shares of common stock of the

Terms of Rights:                        amended in any respect without the consent of the
                                        Rights holders on or prior to a Triggering Event;
                                        thereafter, the terms of the Rights and the Rights
                                        Agreement may be amended without the consent of the
                                        Rights holders in order to cure any ambiguities or to
                                        make changes which do not adversely affect the
                                        interests of Rights holders (other than the Acquiring
                                        Person).

Voting Rights:                          Rights will not have any voting rights.

                                        federal income tax purposes.  However, following an
                                        event which renders the Rights exercisable or upon
                                        redemption of the Rights, stockholders may recognize
                                        taxable income.
