     RIGHTS AGREEMENT, dated as of December 11, 2000 (the "Agreement"), between
Sybron International Corporation (proposed to be renamed Apogent Technologies

national banking association (the "Rights Agent").

                               W I T N E S S E T H

     WHEREAS, pursuant to that certain Contribution Agreement, Plan and
Agreement of Reorganization and Distribution, dated as of November 28, 2000, by
and between the Company and Sybron Dental Specialties, Inc. (formerly known as
SDS Holding Co.) ("SDS"), all of SDS's outstanding shares of common stock are,
on the date hereof, being distributed, pro rata, to the shareholders of the
Company (the "Distribution"); and

     WHEREAS, as of December 11, 2000 (the "Rights Dividend Declaration Date"),
the Board of Directors of the Company authorized and declared, in connection
with the completion of the Distribution, a dividend distribution of one Right
(as hereinafter defined) for each share of Common Stock (as hereinafter defined)
of the Company outstanding at the close of business on December 12, 2000 (the
"Record Date"), and has authorized the issuance of one Right (as such number may
hereinafter be adjusted pursuant to the provisions of Section 11(p) hereof) for
each share of Common Stock of the Company issued between the Record Date
(whether originally issued or delivered from the Company's treasury) and the
Distribution Date (as hereinafter defined) each Right initially representing the
right to purchase one one-hundredth of a share of Series A Preferred Stock of
the Company (the "Preferred Stock") having the rights, powers and preferences
set forth in the form of Certificate of Designation, Preferences and Rights
attached hereto as Exhibit A, upon the terms and subject to the conditions
hereinafter set forth (the "Rights");

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

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

          (a) "Acquiring Person" shall mean any Person who or which, together
with all Affiliates and Associates of such Person, shall be the Beneficial Owner
of 15% or more of the shares of Common Stock then outstanding, but shall not
include (i) the Company, (ii) any Subsidiary of the Company, (iii) any employee
benefit plan of the Company, or of any Subsidiary of the Company, or any Person
or entity organized, appointed or established by the

<PAGE>   5

Company for or pursuant to the terms of any such plan, (iv) any Person who
becomes the Beneficial Owner of fifteen percent (15%) or more of the shares of
Common Stock then out standing as a result of a reduction in the number of
shares of Common Stock outstanding due to the repurchase of shares of Common
Stock by the Company unless and until such Person, after becoming aware that
such Person has become the Beneficial Owner of fifteen percent (15%) or more of
the then outstanding shares of Common Stock, acquires beneficial ownership of
additional shares of Common Stock representing one percent (1%) or more of the
shares of Common Stock then outstanding, or (v) any such Person who has reported
or is required to report such ownership (but less than 20%) on Schedule 13G
under the Securities and Exchange Act of 1934, as amended, and in effect on the
date of the Agreement (the "Exchange Act") (or any comparable or successor
report) or on Schedule 13D under the Exchange Act (or any comparable or
successor report) which Schedule 13D does not state any intention to or reserve
the right to control or influence the management or policies of the Company or
engage in any of the actions specified in Item 4 of such schedule (other than
the disposition of the Common Stock) and, within 10 Business Days of being
requested by the Company to advise it regarding the same, certifies to the
Company that such Person acquired shares of Common Stock in excess of 14.9%
inadvertently or without knowledge of the terms of the Rights and who or which,
together with all Affiliates and Associates, thereafter does not acquire
additional shares of Common Stock while the Beneficial Owner of 15% or more of
the shares of Common Stock then outstanding; provided, however, that if the
Person requested to so certify fails to do so within 10 Business Days, then such
Person shall become an Acquiring Person immediately after such 10-Business-Day
period.

          (b) "Act" shall mean the Securities Act of 1933 as amended.

          (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.

          (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, directly or indirectly, has the right to acquire (whether such
     right is exercisable immediately or only after the passage of time)
     pursuant to any agreement, arrangement or understanding (whether or not in
     writing) or upon the exercise of conversion rights, exchange rights, other
     rights, warrants or options, or otherwise; provided, however, that a Person
     shall not be deemed the "Beneficial Owner" of, or to "beneficially own,"
     (A) securities tendered pursuant to a tender or exchange offer made by such
     Person or any of such Person's Affiliates or Associates until such tendered
     securities are accepted for purchase or exchange, (B) securities issuable
     upon exercise of Rights at any time prior to the occurrence of a Triggering
     Event (as hereinafter defined), or (C) securities issuable upon

<PAGE>   6



     exercise of Rights from and after the occurrence of a Triggering Event
     which Rights were acquired by such Person or any of such Person's
     Affiliates or Associates prior to the Distribution Date (as hereinafter
     defined) or pursuant to Section 3(a) or Section 22 hereof (the "Original
     Rights") or pursuant to Section 11(i) hereof in connection with an
     adjustment made with respect to any Original Rights;

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

               (iii) which are beneficially owned, directly or indirectly, by
     any other Person (or any Affiliate or Associate thereof) with which such
     Person (or any of such Person's Affiliates or Associates) has any
     agreement, arrangement or understanding (whether or not in writing), for
     the purpose of acquiring, holding, voting (except pursuant to a revocable
     proxy as described in the proviso to subparagraph (ii) of this paragraph
     (d)) or disposing of any voting securities of the Company; provided,
     however, that nothing in this paragraph (d) shall cause a Person engaged in
     business as an underwriter of securities to be the "Beneficial Owner" of,
     or to "beneficially own," any securities acquired through such Person's
     participation in good faith in a firm commitment underwriting until the
     expiration of forty days after the date of such acquisition, and then only
     if such securities continue to be owned by such Person at such expiration
     of forty days.

          (e) "Business Day" shall mean any day other than a Saturday, Sunday or
a day on which banking institutions in the State of New York are authorized or

York City time, on such date; provided, however, that if such date is not a
Business Day, it shall mean 5:00 P.M., New York City time, on the next
succeeding Business Day.

          Section 3. Issuance of Rights Certificates.

               (a) Until the earlier of (i) the close of business on the tenth
Business Day after the Stock Acquisition Date (or, if the tenth Business Day
after the Stock Acquisition Date occurs before the Record Date, the close of
business on the Record Date), or (ii) the close of business on the tenth
Business Day (or such later date as the Board shall determine) after the date
that a tender or exchange offer by any Person (other than the Company, any
Subsidiary of the Company, any employee benefit plan of the Company or of any
Subsidiary of the Company, or any Person or entity organized, appointed or
established by the Company for or pursuant to the terms of any such plan) is
first published or sent or given within the meaning of Rule 14d-2(a) of the
General Rules and Regulations under the Exchange Act, if upon consummation
thereof, such Person would become an Acquiring Person, in either instance other
than pursuant to a Qualified Offer (the earlier of (i) and (ii) being herein
referred to as the "Distribution Date"), (x) the Rights will be evidenced
(subject to the provisions of paragraph (b) of this Section 3) by the
certificates for the Common Stock registered in the names of the holders of the
Common Stock (which certificates for Common Stock shall be deemed also to be
certificates for Rights) and not by separate certificates, and (y) the Rights
will be transferable only in connection with the transfer of the underlying
shares of Common Stock (including a transfer to the Company). As soon as
practicable after the Distribution Date, the Rights Agent will send by
first-class, insured, postage-prepaid mail, to each record holder of the Common
Stock as of the close of business on the Distribution Date, at the address of
such holder shown on the records of the Company, one or more rights
certificates, in substantially the form of Exhibit B hereto (the "Rights
Certificates"), evidencing one Right for each share of Common Stock so held,
subject to adjustment as provided herein. In the event that an adjustment in the
number of Rights per share of Common Stock has been made pursuant to Section
11(p) hereof, at the time of distribution of the Rights Certificates,

                                       6

<PAGE>   10



the Company shall make the necessary and appropriate rounding adjustments (in
accordance with Section 14(a) hereof) so that Rights Certificates representing
only whole numbers of Rights are distributed and cash is paid in lieu of any
fractional Rights. As of and after the Distribution Date, the Rights will be
evidenced solely by such Rights Certificates.

               (b) The Company will make available, as promptly as practicable
following the Record Date, a copy of a Summary of Rights, in substantially the
form attached hereto as Exhibit C (the "Summary of Rights") to any holder of
Rights who may so request from time to time prior to the Expiration Date. With
respect to certificates for the Common Stock out standing as of the Record Date,
until the Distribution Date, the Rights will be evidenced by such certificates
for the Common Stock and the registered holders of the Common Stock shall also
be the registered holders of the associated Rights. Until the earlier of the
Distribution Date or the Expiration Date (as such term is defined in Section
7(a) hereof), the transfer of any certificates representing shares of Common
Stock in respect of which Rights have been issued shall also constitute the
transfer of the Rights associated with such shares of Common Stock.

               (c) Rights shall be issued in respect of all shares of Common
Stock which are issued (whether originally issued or from the Company's
treasury) after the Record Date but prior to the earlier of the Distribution
Date or the Expiration Date. Certificates representing such shares of Common
Stock shall also be deemed to be certificates for Rights, and shall bear the
following legend:

          This certificate also evidences and entitles the holder hereof to
     certain Rights as set forth in the Rights Agreement between Sybron
     International Corporation [after the name change: "Apogent Technologies
     Inc. (formerly known as Sybron International Corporation)"] (the "Company")
     and the Rights Agent thereunder (the "Rights Agreement"), the terms of
     which are hereby incorporated herein by reference and a copy of which is on
     file at the principal offices of the Rights Agent. Under certain
     circumstances, as set forth in the Rights Agreement, such Rights will be
     evidenced by separate certificates and will no longer be evidenced by this
     certificate. The Rights Agent will mail to the holder of this certificate a
     copy of the Rights Agreement, as in effect on the date of mailing, without
     charge, promptly after receipt of a written request therefor. Under certain
     circumstances set forth in the Rights Agreement, Rights issued to, or held
     by, any Person who is, was or becomes an Acquiring Person or any Affiliate
     or Associate thereof (as such terms are defined in the Rights Agreement),
     whether currently held by or on behalf of such Person or by any subsequent
     holder, may become null and void.

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


                                       7

<PAGE>   11



transfer of any of such certificates shall also constitute the transfer of the
Rights associated with the Common Stock represented by such certificates.

          Section 4. Form of Rights Certificates.

               (a) The Rights Certificates (and the forms of election to
purchase and of assignment to be printed on the reverse thereof) shall each be
substantially in the form set forth in Exhibit B hereto and may have such marks
of identification or designation and such legends, summaries or endorsements
printed thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Agreement, or as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any stock exchange on which the Rights may from time to
time be listed, or to conform to usage. Subject to the provisions of Section 11
and Section 22 hereof, the Rights Certificates, whenever distributed, shall be
dated as of the Record Date and on their face shall entitle the holders thereof
to purchase such number of one one-hundredths of a share of Preferred Stock as
shall be set forth therein at the price set forth therein (such exercise price
per one one-hundredth of a share, the "Purchase Price"), but the amount and
type of securities purchasable upon the exercise of each Right and the Purchase
Price thereof shall be subject to adjustment as provided herein.

               (b) Any Rights Certificate issued pursuant to Section 3(a),
Section 11(i) 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 the Board of Directors of the Company has
determined is part of a plan, arrangement or understanding which has as a
primary purpose or effect the avoidance of 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 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.

          Section 5. Countersignature and Registration.

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

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

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

               (a) Subject to the provisions of Section 4(b), Section 7(e) and
Section 14 hereof, at any time after the close of business on the Distribution
Date, and at or prior to the close of business on the Expiration Date, any
Rights Certificate or Certificates (other than Rights Certificates representing
Rights that may have been exchanged pursuant to Section 24 hereof) may be
transferred, split up, combined or exchanged for another Rights Certificate or
Certificates, entitling the registered holder to purchase a like number of one
one-hundredths of a share of Preferred Stock (or, following a Triggering Event,
Common Stock, other securities, cash or other assets, as the case may be) as the
Rights Certificate or Certificates surrendered then entitles such holder (or
former holder in the case of a transfer) to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Rights Certificate or
Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Rights Certificate or Certificates to be transferred,
split up, combined or exchanged at the principal office or offices of the Rights
Agent designated for such purpose. Neither the Rights Agent nor the Company
shall be obligated to take any action whatsoever with respect to the transfer of
any such surrendered Rights Certificate until the registered holder shall have
completed and signed the


                                       9
<PAGE>   13



certificate contained in the form of assignment on the reverse side of such
Rights Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request. Thereupon the Rights
Agent shall, subject to Section 4(b), Section 7(e), Section 14 and Section 24
hereof, countersign and deliver to the Person entitled thereto a Rights
Certificate or 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 reimbursement to the Company
and the Rights Agent of all reasonable expenses incidental thereto, and upon
surrender to the Rights Agent and cancellation of the Rights Certificate, if
mutilated, the Company will execute and deliver a new Rights Certificate of like
tenor to the Rights Agent for countersignature and delivery to the registered
owner in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated.

     Section 14. Exercise of Rights; Purchase Price; Expiration Date of Rights.

               (a) Subject to Section 7(e) hereof, at any time after the
Distribution Date the registered holder of any Rights Certificate may exercise
the Rights evidenced thereby (except as otherwise provided herein including,
without limitation, the restrictions on exercisability set forth in Section
9(c), Section 11(a)(iii) and Section 23(a) hereof) in whole or in part upon
surrender of the Rights Certificate, with the form of election to purchase and
the certificate on the reverse side thereof duly executed, to the Rights Agent
at the principal office or offices of the Rights Agent designated for such
purpose, together with payment of the aggregate Purchase Price with respect to
the total number of one one-hundredths of a share (or other securities, cash or
other assets, as the case may be) as to which such surrendered Rights are then
exercisable, at or prior to the earlier of (i) 5:00 P.M., New York City time, on
December 12, 2010, or such later date as may be established by the Board of
Directors prior to the expiration of the Rights (such date, as it may be
extended by the Board, the ("Final Expiration Date"), or (ii) the time at which
the Rights are redeemed or exchanged as provided in Section 23 and Section 24
hereof (the earlier of (i) and (ii) being herein referred to as the "Expiration
Date").

               (b) The Purchase Price for each one one-hundredth of a share of
Preferred Stock pursuant to the exercise of a Right initially shall be $140,
shall be subject to adjustment from time to time as provided in Section 11 and
Section 13(a) hereof and shall be payable in accordance with paragraph (c)
below.

               (c) Upon receipt of a Rights Certificate representing exercisable
Rights, with the form of election to purchase and the certificate duly executed,
accompanied by payment, with respect to each Right so exercised, of the Purchase
Price per one one-hundredth of


                                       10
<PAGE>   14



a share of Preferred Stock (or other shares, securities, cash or other assets,
as the case may be) to be purchased as set forth below and an amount equal to
any applicable transfer tax, the Rights Agent shall, subject to Section 20(k)
hereof, thereupon promptly (i) (A) requisition from any transfer agent of the
shares of Preferred Stock (or make available, if the Rights Agent is the
transfer agent for such shares) certificates for the total number of one
one-hundredths of a share of Preferred Stock to be purchased and the Company
hereby irrevocably authorizes its transfer agent to comply with all such
requests, or (B) if the Company shall have elected to deposit the total number
of shares of Preferred Stock issuable upon exercise of the Rights hereunder with
a depositary agent, requisition from the depositary agent depositary receipts
representing such number of one one-hundredths of a share of Preferred Stock as
are to be purchased (in which case certificates for the shares of Preferred
Stock represented by such receipts shall be deposited by the transfer agent with
the depositary agent) and the Company will direct the depositary agent to comply
with such request, (ii) requisition from the Company the amount of cash, if any,
to be paid in lieu of fractional shares in accordance with Section 14 hereof,
(iii) after receipt of such certificates or depositary receipts, cause the same
to be delivered to or, upon the order of the registered holder of such Rights
Certificate, registered in such name or names as may be designated by such
holder, and (iv) after receipt thereof, deliver such cash, if any, to or upon
the order of the registered holder of such Rights Certificate. The payment of
the Purchase Price (as such amount may be reduced pursuant to Section 11(a)(iii)
hereof) shall be made in cash or by certified bank check or bank draft payable
to the order of the Company. In the event that the Company is obligated to issue
other securities (including Common Stock) of the Company, pay cash and/or
distribute other property pursuant to Section 11(a) hereof, the Company will
make all arrangements necessary so that such other securities, cash and/or other
property are available for distribution by the Rights Agent, if and when
appropriate. The Company reserves the right to require prior to the occurrence
of a Triggering Event that, upon any exercise of Rights, a number of Rights be
exercised so that only whole shares of Preferred Stock be issued.

               (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 remaining unexercised shall be issued by the Rights Agent and
delivered to, or upon the order of, the registered holder of such Rights
Certificate, registered in such name or names as may be designated by such
holder, subject to the provisions of Section 14 hereof.

               (e) Notwithstanding anything in this Agreement to the contrary,
from and after the first occurrence of a Section 11(a)(ii) Event, any Rights
beneficially owned by (i) an Acquiring Person 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, 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
the Acquiring Person has any continuing agreement, arrangement or understanding
regarding the transferred Rights or (B) a transfer which the Board


                                       11

<PAGE>   15



of Directors of the Company has determined is part of a plan, arrangement or
understanding which has as a primary purpose or effect the avoidance of this
Section 7(e), shall become null and void without any further action and no
holder of such Rights shall have any rights whatsoever with respect to such
Rights, whether under any provision of this Agreement or otherwise. The Company
shall use all reasonable efforts to insure that the provisions of this Section
7(e) and Section 4(b) hereof are complied with, but shall have no liability to
any holder of Rights Certificates or any other Person as a result of its failure
to make any determinations with respect to an Acquiring Person or any of its
Affiliates, Associates or transferees hereunder.

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

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

          Section 9. Reservation and Availability of Capital Stock.

               (a) The Company covenants and agrees that it will cause to be
reserved and kept available out of its authorized and unissued shares of
Preferred Stock (and, following the occurrence of a Triggering Event, out of its
authorized and unissued shares of Common Stock and/or other securities or out of
its authorized and issued shares held in its treasury), the number of shares of
Preferred Stock (and, following the occurrence of a Triggering Event, Common
Stock and/or other securities) that, as provided in this Agreement including
Section 11(a)(iii) hereof, will be sufficient to permit the exercise in full of
all outstanding Rights.

               (b) So long as the shares of Preferred Stock (and, following the
occurrence of a Triggering Event, Common Stock and/or other securities) issuable
and deliverable upon the exercise of the Rights may be listed on any national
securities exchange, the
                                       12

<PAGE>   16



Company shall use its best efforts to cause, from and after such time as the
Rights become exercisable, all shares reserved for such issuance to be listed on
such exchange upon official notice of issuance upon such exercise.

               (c) The Company shall use its best efforts to (i) file, as soon
as practicable following the earliest date after the first occurrence of a
Section 11(a)(ii) Event on which the consideration to be delivered by the
Company upon exercise of the Rights has been determined in accordance with
Section 11(a)(iii) hereof, a registration statement under the Act, with respect
to the securities purchasable upon exercise of the Rights on an appropriate
form, (ii) cause such registration statement to become effective as soon as
practicable after such filing, and (iii) cause such registration statement to
remain effective (with a prospectus at all times meeting the requirements of the
Act) until the earlier of (A) the date as of which the Rights are no longer
exercisable for such securities, and (B) the date of the expiration of the
Rights. The Company will also take such action as may be appropriate under, or
to ensure compliance with, the securities or "blue sky" laws of the various
states in connection with the exercisability of the Rights. The Company may
temporarily suspend, for a period of time not to exceed ninety (90) days after
the date set forth in clause (i) of the first sentence of this Section 9(c), the
exercisability of the Rights in order to prepare and file such registration
statement and permit it to become effective. Upon any such suspension, the
Company shall issue a public announcement stating that the exercisability of the
Rights has been temporarily suspended, as well as a public announcement at such
time as the suspension has been rescinded. In addition, if the Company shall
determine that a registration statement is required following the Distribution
Date, the Company may temporarily suspend the exercisability of the Rights until
such time as a registration statement has been declared effective.
Notwithstanding any provision of this Agreement to the contrary, the Rights
shall not be exercisable in any jurisdiction if the requisite qualification in
such jurisdiction shall not have been obtained, the exercise thereof shall not
be permitted under applicable law, or a registration statement shall not have
been declared effective.

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

               (e) The Company further covenants and agrees that it will pay
when due and payable any and all federal and state transfer taxes and charges
which may be payable in respect of the issuance or delivery of the Rights
Certificates and of any certificates for a number of one one-hundredths of a
share of Preferred Stock (or Common Stock and/or other securities, as the case
may be) upon the exercise of Rights. The Company shall not, however, be required
to pay any 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 a number of one one-hundredths of a share of Preferred Stock (or
Common Stock and/or other securities, as the case may be) in


                                       13
<PAGE>   17



respect of a name other than that of the registered holder of the Rights
Certificates evidencing Rights surrendered for exercise or to issue or deliver
any certificates for a number of one one-hundredths of a share of Preferred
Stock (or Common Stock and/or other securities, as the case may be) in a name
other than that of the registered holder upon the exercise of any Rights until
such tax shall have been paid (any such tax being payable by the holder of such
Rights Certificates at the time of surrender) or until it has been established
to the Company's satisfaction that no such tax is due.

               Section 10. Preferred Stock Record Date. Each person in whose
name any certificate for a number of one one-hundredths of a share of Preferred
Stock (or Common Stock and/or other securities, as the case may be) is issued
upon the exercise of Rights shall for all purposes be deemed to have become the
holder of record of such fractional shares of Preferred Stock (or Common Stock
and/or other securities, as the case may be) represented thereby on, and such
certificate shall be dated, the date upon which the Rights Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and all applicable transfer taxes) was made; provided, however, that if the
date of such surrender and payment is a date upon which the Preferred Stock (or
Common Stock and/or other securities, as the case may be) transfer books of the
Company are closed, such Person shall be deemed to have become the record holder
of such shares (fractional or otherwise) on, and such certificate shall be
dated, the next succeeding Business Day on which the Preferred Stock (or Common
Stock and/or other securities, as the case may be) transfer books of the Company
are open. Prior to the exercise of the Rights evidenced thereby, the holder of a
Rights Certificate shall not be entitled to any rights of a stockholder of the
Company with respect to shares for which the Rights shall be exercisable,
including, without limitation, the right to vote, to receive dividends or other
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.

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

                    (a)(i) In the event the Company shall at any time after the
     date of this Agreement (A) declare a dividend on the Preferred Stock
     payable in shares of Preferred Stock, (B) subdivide the outstanding
     Preferred Stock, (C) combine the outstanding Preferred Stock into a smaller
     number of shares, or (D) issue any shares of its capital stock in a
     reclassification of the Preferred Stock (including any such
     reclassification in connection with a consolidation or merger in which the
     Company is the continuing or surviving corporation), except as otherwise
     provided in this Section 11(a) and Section 7(e) hereof, the Purchase Price
     in effect at the time of the record date for such dividend or of the
     effective date of such subdivision, combination or reclassification, and
     the number and kind of shares of Preferred Stock or capital stock, as the
     case may be, issuable on such date, shall

                                       14

<PAGE>   18

     be proportionately adjusted so that the holder of any Right exercised after
     such time shall be entitled to receive, upon payment of the Purchase Price
     then in effect, the aggregate number and kind of shares of Preferred Stock
     or capital stock, as the case may be, which, if such Right had been
     exercised immediately prior to such date and at a time when the Preferred
     Stock transfer books of the Company were open, such holder would have owned
     upon such exercise and been entitled to receive by virtue of such dividend,
     subdivision, combination or reclassification. If an event occurs which
     would require an adjustment under both this Section 11(a)(i) and Section
     11(a)(ii) hereof, the adjustment provided for in this Section 11(a)(i)
     shall be in addition to, and shall be made prior to, any adjustment
     required pursuant to Section 11(a)(ii) hereof.

                    (ii) In the event any Person shall, at any time after the
     Rights Dividend Declaration Date, become an Acquiring Person, unless the
     event causing such Person to become an Acquiring Person is a transaction
     set forth in Section 13(a) hereof, or is an acquisition of shares of Common
     Stock pursuant to a tender offer or an exchange offer for all outstanding
     shares of Common Stock at a price and on terms determined by at least a
     majority of the members of the Board of Directors who are not officers of
     the Company and who are not representatives, nominees, Affiliates or
     Associates of an Acquiring Person, after receiving advice from one or more
     investment banking firms, to be (a) at a price which is fair to
     stockholders and not inadequate (taking into account all factors which such
     members of the Board deem relevant, including, without limitation, prices
     which could reasonably be achieved if the Company or its assets were sold
     on an orderly basis designed to realize maximum value) and (b) otherwise in
     the best interests of the Company and its stockholders (a "Qualified
     Offer") then, promptly following the occurrence of such event, proper
     provision shall be made so that each holder of a Right (except as provided
     below and in Section 7(e) hereof) shall thereafter have the right to
     receive, upon exercise thereof at the then current Purchase Price in
     accordance with the terms of this Agreement, in lieu of a number of one
     one-hundredths of a share of Preferred Stock, such number of shares of
     Common Stock of the Company as shall equal the result obtained by (x)
     multiplying the then current Purchase Price by the then number of one one-
     hundredths of a share of Preferred Stock for which a Right was exercisable
     immediately prior to the first occurrence of a Section 11(a)(ii) Event, and
     (y) dividing that product (which, following such first occurrence, shall
     thereafter be referred to as the "Purchase Price" for each Right and for
     all purposes of this Agreement) by 50% of the Current Market Price
     (determined pursuant to Section 11(d) hereof) per share of Common Stock on
     the date of such first occurrence (such number of shares, the "Adjustment
     Shares").

                    (iii) In the event that the number of shares of Common Stock
     which is authorized by the Company's Restated Articles of Incorporation,


                                       15
<PAGE>   19



     but not outstanding or reserved for issuance for purposes other than upon
     exercise of the Rights, is not sufficient to permit the exercise in full of
     the Rights in accordance with the foregoing subparagraph (ii) of this
     Section 11(a), the Company shall (A) determine the value of the Adjustment
     Shares issuable upon the exercise of a Right (the "Current Value"), and (B)
     with respect to each Right (subject to Section 7(e) hereof), make adequate
     provision to substitute for the Adjustment Shares, upon the exercise of a
     Right and payment of the applicable Purchase Price, (1) cash, (2) a
     reduction in the Purchase Price, (3) Common Stock or other equity
     securities of the Company (including, without limitation, shares, or units
     of shares, of preferred stock, such as the Preferred Stock, which the Board
     has deemed to have essentially the same value or economic rights as shares
     of Common Stock (such shares of preferred stock being referred to as
     "Common Stock Equivalents")), (4) debt securities of the Company, (5) other
     assets, or (6) any combination of the foregoing, having an aggregate value
     equal to the Current Value (less the amount of any reduction in the
     Purchase Price), where such aggregate value has been determined by the
     Board based upon the advice of a nationally recognized investment banking
     firm selected by the Board; provided, however, that if the Company shall
     not have made adequate provision to deliver value pursuant to clause (B)
     above within thirty (30) days following the later of (x) the first
     occurrence of a Section 11(a)(ii) Event and (y) the date on which the
     Company's right of redemption pursuant to Section 23(a) expires (the later
     of (x) and (y) being referred to herein as the "Section 11(a)(ii) Trigger
     Date"), then the Company shall be obligated to deliver, upon the surrender
     for exercise of a Right and without requiring payment of the Purchase
     Price, shares of Common Stock (to the extent available) and then, if
     necessary, cash, which shares and/or cash have an aggregate value equal to
     the Spread. For purposes of the preceding sentence, the term "Spread" shall
     mean the excess of (i) the Current Value over (ii) the Purchase Price. If
     the Board determines in good faith that it is likely that sufficient
     additional shares of Common Stock could be authorized for issuance upon
     exercise in full of the Rights, the thirty (30) day period set forth above
     may be extended to the extent necessary, but not more than ninety (90) days
     after the Section 11(a)(ii) Trigger Date, in order that the Company may
     seek shareholder approval for the authorization of such additional shares
     (such thirty (30) day period, as it may be extended, is herein called the
     "Substitution Period"). To the extent that the Company determines that some
     action should be taken pursuant to the first and/or third sentences of this
     Section 11(a)(iii), the Company (1) shall provide, subject to Section 7(e)
     hereof, that such action shall apply uniformly to all outstanding Rights,
     and (2) may suspend the exercisability of the Rights until the expiration
     of the Substitution Period in order to seek such shareholder approval for
     such authorization of additional shares and/or to decide the appropriate
     form of distribution to be made pursuant to such first sentence and to
     determine the value thereof. In the event of any such suspension, the
     Company shall issue a public announcement stating that the exercisability
     of the Rights has been


                                       16
<PAGE>   20



     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 each Adjustment Share shall be the Current Market Price per
     share of the Common Stock on the Section 11(a)(ii) Trigger Date and the per
     share or per unit value of any Common Stock Equivalent shall be deemed to
     equal the Current Market Price per share of the Common Stock on such date.

                    (b) In case the Company shall fix a record date for the
issuance of rights (other than the Rights), options or warrants to all holders
of Preferred Stock entitling them to subscribe for or purchase (for a period
expiring within forty-five (45) calendar days after such record date) Preferred
Stock (or shares having the same rights, privileges and preferences as the
shares of Preferred Stock ("Equivalent Preferred Stock")) or securities
convertible into Preferred Stock or Equivalent Preferred Stock at a price per
share of Preferred Stock or per share of Equivalent Preferred Stock (or having
a conversion price per share, if a security convertible into Preferred Stock or
Equivalent Preferred Stock) less than the Current Market Price (as determined
pursuant to Section 11(d) hereof) per share of Preferred Stock on such record
date, the Purchase Price to be in effect after such record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the number of shares
of Preferred Stock outstanding on such record date, plus the number of shares of
Preferred Stock which the aggregate offering price of the total number of shares
of Preferred Stock and/or Equivalent Preferred Stock so to be offered (and/or
the aggregate initial conversion price of the convertible securities so to be
offered) would purchase at such Current Market Price, and the denominator of
which shall be the number of shares of Preferred Stock outstanding on such
record date, plus the number of additional shares of Preferred Stock and/or
Equivalent Preferred Stock to be offered for subscription or purchase (or into
which the convertible securities so to be offered are initially convertible).
In case such subscription price may be paid by delivery of consideration, part
or all of which may be in a form other than cash, the value of such
consideration shall be as determined in good faith by the Board of Directors of
the Company, whose determination shall be described in a statement filed with
the Rights Agent and shall be binding on the Rights Agent and the holders of the
Rights. Shares of Preferred Stock owned by or held for the account of the
Company shall not be deemed outstanding for the purpose of any such computation.
Such adjustment shall be made successively whenever such a record date is fixed,
and in the event that such rights or warrants are not so issued, the Purchase
Price shall be adjusted to be the Purchase Price which would then be in effect
if such record date had not been fixed.

                    (c) In case the Company shall fix a record date for a
distribution to all holders of Preferred Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of evidences of indebtedness, cash (other than a regular
quarterly cash dividend out of the earnings or retained earnings of the
Company), assets (other than a dividend payable in Preferred Stock, but
including any dividend payable in stock other than Preferred Stock) or evidences
of indebtedness, or of subscription rights or warrants (excluding those referred
to in Section 11(b) hereof), the Purchase

Price to be in effect after such record date shall be determined by multiplying
the Purchase Price in effect immediately prior to such record date by a
fraction, the numerator of which shall be the Current Market Price (as
determined pursuant to Section 11(d) hereof) per share of Preferred Stock on
such record date, less the fair market value (as determined in good faith by the
Board of Directors 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 share of Preferred Stock, and the denominator of which
shall be such Current Market Price (as determined pursuant to Section 11(d)
hereof) per share of Preferred Stock. Such adjustments shall be made
successively whenever such a record date is fixed, and in the event that such
distribution is not so made, the Purchase Price shall be adjusted to be the
Purchase Price which would have been in effect if such record date had not been
fixed.

                    (d)(i) For the purpose of any computation hereunder, other
than computations made pursuant to Section 11(a)(iii) hereof, the Current Market
Price per share of Common Stock on any date shall be deemed to be the average of
the daily closing prices per share of such Common Stock for the thirty (30)
consecutive Trading Days immediately prior to such date, and for purposes of
computations made pursuant to Section 11(a)(iii) hereof, the Current Market
Price per share of Common Stock on any date shall be deemed to be the average of
the daily closing prices per share of such Common Stock for the ten (10)
consecutive Trading Days immediately following such date; provided, however,
that in the event that the Current Market Price per share of the Common Stock is
determined during a period following the announcement by the issuer of such
Common Stock of (A) a dividend or distribution on such Common Stock payable in
shares of such Common Stock or securities convertible into shares of such Common
Stock (other than the Rights), or (B) any subdivision, combination or
reclassification of such Common Stock, and the ex-dividend date for such
dividend or distribution, or the record date for such subdivision, combination
or reclassification shall not have occurred prior to the commencement of the
requisite thirty (30) Trading Day or ten (10) Trading Day period, as set forth
above, then, and in each such case, the Current Market Price shall be properly
adjusted to take into account ex-dividend trading. The closing price for each
day shall be the last sale price, regular way, or, in case no such sale takes
place on such day, the average of the closing bid and asked prices, regular way,
in either case as reported in the principal consolidated transaction reporting
system with respect to securities listed or admitted to trading on the New York
Stock Exchange or, if the shares of Common Stock are not listed or admitted to
trading on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to securities listed on
the principal national securities exchange on which the shares of Common Stock
are listed or admitted to trading or, if the shares of Common Stock are not
listed or admitted to trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by the National Association
of Securities Dealers Automated Quotation System ("NASDAQ") or such other
system then in use, or, if on any such date the shares of Common Stock are not
quoted by any such organization, the average of the closing bid and asked prices
as furnished by a professional market maker making a market in the


                                       18

<PAGE>   22



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

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

               (e) Anything herein to the contrary notwithstanding, no
adjustment in the Purchase Price shall be required unless such adjustment would
require an increase or decrease of at least one percent (1%) in the Purchase
Price; provided, however, that any adjustments which by reason of this Section
11(e) are not required to be made shall be carried forward and taken into
account in any subsequent adjustment. All calculations under this Section 11
shall be made to the nearest cent or to the nearest ten-thousandth of a share of
Common Stock or other share or one-millionth of a share of Preferred Stock, as
the case may be. Notwithstanding the first sentence of this Section 11(e), any
adjustment required by this Section 11 shall be made no later than the earlier
of (i) three (3) years from the date of the transaction which mandates such
adjustment, or (ii) the Expiration Date.

               (f) If as a result of an adjustment made pursuant to Section
11(a)(ii) or Section 13(a) hereof, the holder of any Right thereafter exercised
shall become entitled to receive any shares of capital stock other than
Preferred Stock, thereafter the number of such other shares so receivable upon
exercise of any Right and the Purchase Price thereof shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the


                                       19
<PAGE>   23



provisions with respect to the Preferred Stock contained in Sections 11(a), (b),
(c), (e), (g), (h), (i), (j), (k) and (m), and the provisions of Sections 7, 9,
10, 13 and 14 hereof with respect to the Preferred Stock shall apply on like
terms to any such other shares.

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

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

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


                                       20

<PAGE>   24



may bear, at the option of the Company, the adjusted Purchase Price) and shall
be registered in the names of the holders of record of Rights Certificates on
the record date specified in the public announcement.

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

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

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

               (m) Anything in this Section 11 to the contrary notwithstanding,
the Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that in their good faith judgment the Board of Directors of the
Company shall determine to be advisable in order that any (i) consolidation or
subdivision of the Preferred Stock, (ii) issuance wholly for cash of any shares
of Preferred Stock at less than the Current Market Price, (iii) issuance wholly
for cash of shares of Preferred Stock or securities which by their terms are
convertible into or exchangeable for shares of Preferred Stock, (iv) stock
dividends or (v) issuance of rights, options or warrants referred to in this
Section 11, hereafter made by the Company to holders of its Preferred Stock
shall not be taxable to such stockholders.

               (n) The Company covenants and agrees that it shall not, at any
time after the Distribution Date, (i) consolidate with any other Person (other
than a Subsidiary of the Company in a transaction which complies with Section
11(o) hereof), (ii) merge with or into any


                                       21

<PAGE>   25



other Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof), or (iii) sell or transfer (or permit any
Subsidiary to sell or transfer), in one transaction, or a series of related
transactions, assets or earning power aggregating more than 50% of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person or Persons (other than the Company and/or any of its Subsidiaries
in one or more transactions each of which complies with Section 11(o) hereof),
if (x) at the time of or immediately after such consolidation, merger or sale
there are any rights, warrants or other instruments or securities outstanding or
agreements in effect which would substantially diminish or otherwise eliminate
the benefits intended to be afforded by the Rights or (y) prior to,
simultaneously with or immediately after such consolidation, merger or sale, the
shareholders of the Person who constitutes, or would constitute, the "Principal
Party" for purposes of Section 13(a) hereof shall have received a distribution
of Rights previously owned by such Person or any of its Affiliates and
Associates.

               (o) The Company covenants and agrees that, after the
Distribution Date, it will not, except as permitted by Section 23 or Section 26
hereof, take (or permit any Subsidiary to take) any action if at the time such
action is taken it is reasonably foreseeable that such action will diminish
substantially or otherwise eliminate the benefits intended to be afforded by the
Rights.

               (p) Anything in this Agreement to the contrary notwithstanding,
in the event that the Company shall at any time after the Rights Dividend
Declaration Date and prior to the Distribution Date (i) declare a dividend on
the outstanding shares of Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding shares of Common Stock, or (iii) combine the
outstanding shares of Common Stock into a smaller number of shares, the number
of Rights associated with each share of Common Stock then outstanding, or issued
or delivered thereafter but prior to the Distribution Date, shall be
proportionately adjusted so that the number of Rights thereafter associated with
each share of Common Stock following any such event shall equal the result
obtained by multiplying the number of Rights associated with each share of
Common Stock immediately prior to such event by a fraction the numerator which
shall be the total number of shares of Common Stock outstanding immediately
prior to the occurrence of the event and the denominator of which shall be the
total number of shares of Common Stock outstanding immediately following the
occurrence of such event.

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

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

          (a) In the event that, following the Stock Acquisition Date, directly
or indirectly, (x) the Company shall consolidate with, or merge with and into,
any other Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof), and the Company shall not be the continuing
or surviving corporation of such consolidation or merger, (y) any Person (other
than a Subsidiary of the Company in a transaction which complies with Section
11(o) hereof) shall consolidate with, or merge with or into, the Company, and
the Company shall be the continuing or surviving corporation of such
consolidation or merger and, in connection with such consolidation or merger,
all or part of the outstanding shares of Common Stock shall be changed into or
exchanged for stock or other securities of any other Person or cash or any other
property, or (z) the Company shall sell or otherwise transfer (or one or more of
its Subsidiaries shall sell or otherwise transfer), in one transaction or a
series of related transactions, assets, cash flow or earning power aggregating
more than 50% of the assets, cash flow or earning power of the Company and its
Subsidiaries (taken as a whole) to any Person or Persons (other than the Company
or any Subsidiary of the Company in one or more transactions each of which
complies with Section 11(o) hereof), then, and in each such case (except as may
be contemplated by Section 13(d) hereof), proper provision shall be made so
that: (i) each holder of a Right, except as provided in Section 7(e) hereof,
shall thereafter have the right to receive, upon the exercise thereof at the
then current Purchase Price in accordance with the terms of this Agreement, such
number of validly authorized and issued, fully paid, non-assessable and freely
tradeable shares of Common Stock of the Principal Party (as such term is
hereinafter defined), not subject to any liens, encumbrances, rights of first
refusal or other adverse claims, as shall be equal to the result obtained by (1)
multiplying the then current Purchase Price by the number of one one-hundredths
of a share of Preferred Stock for which a Right is exercisable immediately prior
to the first occurrence of a Section 13 Event (or, if a Section 11(a)(ii) Event
has occurred prior to the first occurrence of a Section 13 Event, multiplying
the number of such one one-hundredths of a share for which a Right was
exercisable immediately prior to the first occurrence of a Section 11(a)(ii)
Event by the Purchase Price in effect immediately prior to such first occurrence
of a Section 11(a)(ii) Event, and (2) dividing that product (which, following
the first occurrence of a Section 13 Event, shall be referred to as the
"Purchase Price" for each Right and for all purposes of this Agreement) by 50%
of the Current Market Price (determined pursuant to Section 11(d)(i) hereof) per
share of the Common Stock of such Principal Party on the date of consummation of
such Section 13 Event; (ii) such Principal Party shall thereafter be liable for,
and shall assume, by virtue of such Section 13 Event, all the obligations and
duties of the Company pursuant to this Agreement; (iii) the term "Company" shall
thereafter be deemed to refer to such Principal Party, it being specifically
intended that the provisions of Section 11 hereof shall apply only to such
Principal Party following the first occurrence of a Section 13 Event; (iv) such
Principal Party shall take such steps (including, but not limited to, the
reservation of a sufficient number of shares of its Common Stock) in connection
with the consummation of any such transaction as may be necessary to assure that
the provisions hereof shall thereafter be applicable, as nearly as


                                       23

<PAGE>   27



reasonably may be, in relation to its shares of Common Stock thereafter
deliverable upon the exercise of the Rights; and (v) the provisions of Section
11(a)(ii) hereof shall be of no effect following the first occurrence of any
Section 13 Event.

               (b) "Principal Party" shall mean:

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

                    (ii) in the case of any transaction described in clause (z)
     of the first sentence of Section 13(a), the Person that is the party
     receiving the greatest portion of the assets, cash flow or earning power
     transferred pursuant to such transaction or transactions;

provided, however, that in any such case, (1) if the Common Stock of such Person
is not at such time and has not been continuously over the preceding twelve (12)
month period registered under Section 12 of the Exchange Act, and such Person is
a direct or indirect Subsidiary of another Person the Common Stock of which is
and has been so registered, "Principal Party" shall refer to such other Person;
and (2) in case such Person is a Subsidiary, directly or indirectly, of more
than one Person, the Common Stock of two or more of which are and have been so
registered, "Principal Party" shall refer to whichever of such Persons is the
issuer of the Common Stock having the greatest aggregate market value.

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

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


                                       24
<PAGE>   28



                    (ii) take all such other action as may be necessary to
     enable the Principal Party to issue the securities purchasable upon
     exercise of the Rights, including but not limited to the registration or
     qualification of such securities under all requisite securities laws of
     jurisdictions of the various states and the listing of such securities on
     such exchanges and trading markets as may be necessary or appropriate; and

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

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

               (d) Notwithstanding anything in this Agreement to the contrary,
Section 13 shall not be applicable to a transaction described in subparagraphs
(x) and (y) of Section 13(a) if (i) such transaction is consummated with a
Person or Persons who acquired shares of Common Stock pursuant to a tender offer
or exchange offer for all outstanding shares of Common Stock which is a
Qualified Offer as such term is defined in Section 11(a)(ii) hereof (or a wholly
owned subsidiary of any such Person or Persons), (ii) the price per share of
Common Stock offered in such transaction is not less than the price per share of
Common Stock paid to all holders of shares of Common Stock whose shares were
purchased pursuant to such tender offer or exchange offer and (iii) the form of
consideration being offered to the remaining holders of shares of Common Stock
pursuant to such transaction is the same as the form of consideration paid
pursuant to such tender offer or exchange offer. Upon consummation of any such
transaction contemplated by this Section 13(d), all Rights hereunder shall
expire.

          Section 14. Fractional Rights and Fractional Shares.

               (a) The Company shall not be required to issue fractions of
Rights, except prior to the Distribution Date as provided in Section 11(p)
hereof, or to distribute Rights Certificates which evidence fractional Rights.
In lieu of such fractional Rights, the Company shall pay to the registered
holders of the Rights Certificates with regard to which such fractional Rights
would otherwise be issuable, an amount in cash equal to the same fraction of the
current market value of a whole Right. For purposes of this Section 14(a), the
current market value of a whole Right shall be the closing price of the Rights
for the Trading Day immediately prior to the date on which such fractional
Rights would have been otherwise issuable. The closing price of the Rights for
any day shall be the last sale price, regular way, or, in case no such sale
takes place on such day, the average of the closing bid and asked prices,
regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities


                                       25

<PAGE>   29



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

               (b) The Company shall not be required to issue fractions of
shares of Preferred Stock (other than fractions which are integral multiples of
one one-hundredth of a share of Preferred Stock) upon exercise of the Rights or
to distribute certificates which evidence fractional shares of Preferred Stock
(other than fractions which are integral multiples of one one-hundredth of a
share of Preferred Stock). In lieu of fractional shares of Preferred Stock that
are not integral multiples of one one-hundredth of a share of Preferred Stock,
the Company may pay to the registered holders of Rights Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of one one-hundredth of a share of
Preferred Stock. For purposes of this Section 14(b), the current market value of
one one-hundredth of a share of Preferred Stock shall be one one-hundredth of
the closing price of a share of Preferred Stock (as determined pursuant to
Section 11(d)(ii) hereof) for the Trading Day immediately prior to the date of
such exercise.

               (c) Following the occurrence of a Triggering Event, the Company
shall not be required to issue fractions of shares of Common Stock upon exercise
of the Rights or to distribute certificates which evidence fractional shares of
Common Stock. In lieu of fractional shares of Common Stock, the Company may pay
to the registered holders of Rights Certificates at the time such Rights are
exercised as herein provided an amount in cash equal to the same fraction of the
current market value of one (1) share of Common Stock. For purposes of this
Section 14(c), the current market value of one share of Common Stock shall be
the closing price per share of Common Stock (as determined pursuant to Section
11(d)(i) hereof) on the Trading Day immediately prior to the date of such
exercise.

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

          Section 15. Rights of Action. All rights of action in respect of this
Agreement are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Stock); and any registered holder of any


                                       26

<PAGE>   30



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

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

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

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

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

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

          Section 17. Rights Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Rights Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the number of one
one-hundredths of a share of Preferred Stock or any other securities of the
Company which may at any time be issuable on the exercise of the Rights
represented thereby, nor shall anything contained herein or in any Rights
Certificate be construed to confer upon the holder of any Rights Certificate, as
such, any of the rights of a stockholder of the Company or any right to vote for
the election of directors or upon any matter submitted to 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.

          Section 18. Concerning the Rights Agent.

               (a) The Company agrees to pay to the Rights Agent reasonable
compensation for all services rendered by it hereunder and, from time to time,
on demand of the Rights Agent, its reasonable expenses and counsel fees and
disbursements and other disbursements incurred in the administration and
execution of this Agreement and the exercise and performance of its duties
hereunder. The Company also agrees to indemnify the Rights Agent for, and to
hold it harmless against, any loss, liability, 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 Agreement, including the costs and
expenses of defending against any claim of liability in the premises.

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

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

               (a) Any corporation into which the Rights Agent or any successor
Rights Agent may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which the Rights Agent
or any successor Rights Agent shall be a party, or any corporation succeeding to
the corporate trust, stock transfer or other shareholder services business of
the Rights Agent or any successor Rights Agent, shall be the successor to the
Rights Agent under this Agreement without the execution or filing of any paper
or any further act on the part of any of the parties hereto; but only if such
corporation would be eligible


                                       28

<PAGE>   32



for appointment as a successor Rights Agent under the provisions of Section 21
hereof. In case at the time such successor Rights Agent shall succeed to the
agency created by this Agreement, any of the Rights Certificates shall have been
countersigned but not delivered, any such successor Rights Agent may adopt the
countersignature of a predecessor Rights Agent and deliver such Rights
Certificates so countersigned; and in case at that time any of the Rights
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Rights Certificates either in the name of the predecessor or in
the name of the successor Rights Agent; and in all such cases such Rights
Certificates shall have the full force provided in the Rights Certificates and
in this Agreement.

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

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

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

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

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



                                       29
<PAGE>   33



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

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

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

               (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from the
Chairman of the Board, the Chief Executive Officer, the President, any Vice
President, the Chief Financial Officer, the Chief Operating Officer, the
Secretary, any Assistant Secretary, the Treasurer or any Assistant Treasurer of
the Company, and to apply to such officers for advice or instructions in
connection with its duties, and it shall not be liable for any action taken or
suffered to be taken by it in good faith in accordance with instructions of any
such officer.

               (h) The Rights Agent and any stockholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to the
Company or otherwise act as fully and freely as though it were not Rights Agent
under this 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,


                                       30

<PAGE>   34



default, neglect or misconduct of any such attorneys or agents or for any loss
to the Company resulting from any such act, default, neglect or misconduct;
provided, however, reasonable care was exercised in the selection and continued
employment thereof.

               (j) No provision of this Agreement shall require the Rights Agent
to expend or risk its own funds or otherwise incur any financial liability in
the performance of any of its duties 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.

          Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon thirty (30) days' notice in writing mailed to the Company, and to each
transfer agent of the Common Stock and Preferred Stock, by registered or
certified mail, and, if such resignation occurs after the Distribution Date, to
the registered holders of the Rights Certificates by first-class mail. The
Company may remove the Rights Agent or any successor Rights Agent upon thirty
(30) days' notice in writing, mailed to the Rights Agent or successor Rights
Agent, as the case may be, and to each transfer agent of the Common Stock and
Preferred Stock, by registered or certified mail, and, if such removal occurs
after the Distribution Date, to the holders of the Rights Certificates by
first-class mail. If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent. If the Company shall fail to make such appointment within a
period of thirty (30) days after giving notice of such removal or after it has
been notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of a Rights Certificate (who shall,
with such notice, submit his Rights Certificate for inspection by the Company),
then any registered holder of any Rights Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent. Any successor
Rights Agent, whether appointed by the Company or by such a court, shall be (a)
a legal business entity 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 stock transfer or
shareholder services powers or (b) an affiliate of a legal business entity
described in clause (a) of this sentence. After appointment, the successor
Rights Agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named as Rights Agent without
further act or deed; but the prede cessor 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


                                       31

<PAGE>   35



Company shall file notice thereof in writing with the predecessor Rights Agent
and each transfer agent of the Common Stock and the Preferred Stock, and, if
such appointment occurs after the Distribution Date, mail a notice thereof in
writing to the registered holders of the Rights Certificates. Failure to give
any notice provided for in this Section 21, however, or any defect therein,
shall not affect the legality or validity of the resignation or removal of the
Rights Agent or the appointment of the successor Rights Agent, as the case may
be.

          Section 22. Issuance of New Rights Certificates. Notwithstanding any
of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Rights Certificates evidencing Rights in
such form as may be approved by the Board of Directors to reflect any adjustment
or change in the Purchase Price and the number or kind or class of shares or
other securities or property purchasable under the Rights Certificates made in
accordance with the provisions of this Agreement. In addition, in connection
with the issuance or sale of shares of Common Stock following the Distribution
Date and prior to the redemption or expiration of the Rights, the Company (a)
shall, with respect to shares of Common Stock so issued or sold pursuant to the
exercise of stock options or under any employee plan or arrangement, granted or
awarded as of the Distribution Date, 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 if, and to the extent that, the Company shall
be advised by counsel that such issuance would create a significant risk of
material adverse tax consequences to the Company or the Person to whom such
Rights Certificate would be issued, and (ii) no such Rights Certificate shall be
issued if, and to the extent that, appropriate adjustment shall otherwise have
been made in lieu of the issuance thereof.

          Section 23. Redemption and Termination.

               (a) The Board of Directors of the Company may, at its option, at
any time prior to the earlier of (i) the close of business on the tenth Business
Day following the Stock Acquisition Date (or, if the Stock Acquisition Date
shall have occurred prior to the Record Date, the close of business on the tenth
Business Day following the Record Date), or (ii) the Final Expiration Date,
redeem all but not less than all of the then outstanding Rights at a redemption
price of $.01 per Right, as such amount may be appropriately adjusted to reflect
any stock split, stock dividend or similar transaction occurring after the date
hereof (such redemption price being hereinafter referred to as the "Redemption
Price"). Notwithstanding anything contained in this Agreement to the contrary,
the Rights shall not be exercisable after the first occurrence of a Section
11(a)(ii) Event until such time as the Company's right of redemption hereunder
has expired. The Company may, at its option, pay the Redemption Price in cash,
shares of Common Stock (based on the Current Market Price, as defined in Section
11(d)(i) hereof, of the Common Stock at the time of redemption) or any other
form of consideration deemed appropriate by the Board of Directors.



                                       32

<PAGE>   36



               (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 for
each Right so held. Promptly after the action of the Board of Directors ordering
the redemption of the Rights, the Company shall give notice of such redemption
to the Rights Agent and the holders of the then outstanding Rights by mailing
such notice to all such holders at each holder's last address as it appears upon
the registry books of the Rights Agent or, prior to the Distribution Date, on
the registry books of the transfer agent for the Common Stock. Any notice which
is mailed in the manner herein provided shall be deemed given, whether or not
the holder receives the notice. Each such notice of redemption will state the
method by which the payment of the Redemption Price will be made.

          Section 24. Exchange.

               (a) The Board of Directors of the Company may, at its option, at
any time after any Person becomes an Acquiring Person, exchange all or part of
the then outstanding and exercisable Rights (which shall not include Rights that
have become void pursuant to the provisions of Section 7(e) hereof) for Common
Stock at an exchange ratio of one share of Common Stock per Right, appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such exchange ratio being hereinafter referred
to as the "Exchange Ratio"). Notwithstanding the foregoing, the Board of
Directors of the Company shall not be empowered to effect such exchange at any
time after any Person (other than the Company, any Subsidiary of the Company,
any employee benefit plan of the Company or any such Subsidiary, or any entity
holding Common Stock for or pursuant to the terms of any such plan), together
with all Affiliates and Associates of such Person, becomes the Beneficial Owner
of 50% or more of the Common Stock then outstanding.

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



                                       33

<PAGE>   37



               (c) In any exchange pursuant to this Section 24, the Company, at
its option, may substitute Preferred Stock (or Equivalent Preferred Stock, as
such term is defined in paragraph (b) of Section 11 hereof) for Common Stock
exchangeable for Rights, at the initial rate of one one-hundredth of a share of
Preferred Stock (or Equivalent Preferred Stock) for each share of Common Stock,
as appropriately adjusted to reflect stock splits, stock dividends and other
similar transactions after the date hereof.

               (d) In the event that there shall not be sufficient shares of
Common Stock issued but not outstanding or authorized but unissued to permit any
exchange of Rights as contemplated in accordance with this Section 24, the
Company shall take all such action as may be necessary to authorize additional
shares of Common Stock for issuance upon exchange of the Rights.

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

     Section 25. Notice of Certain Events.

               (a) In case the Company shall propose, at any time after the
Distribution Date, (i) to pay any dividend payable in stock of any class to the
holders of Preferred Stock or to make any other distribution to the holders of
Preferred Stock (other than a regular quarterly cash dividend out of earnings or
retained earnings of the Company), (ii) to offer to the holders of Preferred
Stock rights or warrants to subscribe for or to purchase any additional shares
of Preferred Stock or shares of stock of any class or any other securities,
rights or options, (iii) to effect any reclassification of its Preferred Stock
(other than a reclassification involving only the subdivision of outstanding
shares of Preferred Stock), (iv) to effect any consolidation or merger into or
with any other Person (other than a Subsidiary of the Company in a transaction
which complies with Section 11(o) hereof), or to effect any sale or other
transfer (or to permit one or more of its Subsidiaries to effect any sale or
other transfer), in one transaction or a series of related transactions, of more
than 50% of the assets, cash flow or earning power of the Company and its
Subsidiaries (taken as a whole) to any other Person or Persons (other than the
Company and/or any of its Subsidiaries in one or more transactions each of which
complies with Section 11(o) hereof), or (v) to effect the liquidation,
dissolution or winding up of the Company, then, in each such case, the Company
shall give to each holder of a Rights Certificate, to the extent feasible and in
accordance with Section 26 hereof, a notice of such proposed action, which shall
specify the record date for the purposes of such stock dividend, distribution of
rights or warrants,



                                       34

<PAGE>   38



or the date on which such reclassification, consolidation, merger, sale,
transfer, liquidation, dissolution, or winding up is to take place and the date
of participation therein by the holders of the shares of Preferred Stock, if any
such date is to be fixed, and such notice shall be so given in the case of any
action covered by clause (i) or (ii) above at least twenty (20) days prior to
the record date for determining holders of the shares of Preferred Stock for
purposes of such action, and in the case of any such other action, at least
twenty (20) days prior to the date of the taking of such proposed action or the
date of participation therein by the holders of the shares of Preferred Stock,
whichever shall be the earlier.

               (b) In case any of the events set forth in Section 11(a)(ii)
hereof shall occur, then, in any such case, (i) the Company shall as soon as
practicable thereafter give to each holder of a Rights Certificate, to the
extent feasible and in accordance with Section 26 hereof, a notice of the
occurrence of such event, which shall specify the event and the consequences of
the event to holders of Rights under Section 11(a)(ii) hereof, and (ii) all
references in the preceding paragraph to Preferred Stock shall be deemed
thereafter to refer to Common Stock and/or, if appropriate, other securities.

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

of Rights Certificates in order (i) to cure any ambiguity, (ii) to correct or
supplement any provision contained herein which may be defective or inconsistent
with any other provisions herein, (iii) to shorten or lengthen any time period
hereunder, or (iv) to change or supplement the provisions hereunder in any
manner which the Company may deem necessary or desirable and which shall not
adversely affect the interests of the holders of Rights Certificates (other than
an Acquiring Person or an Affiliate or Associate of an Acquiring Person);
provided, this Agreement may not be supplemented or amended, pursuant to clause
(iii) of this sentence to lengthen, (A) any time period relating to when the
Rights may be redeemed at such time as the Rights are not then redeemable, or
(B) any other time period unless such lengthening is for the purpose of
protecting, enhancing or clarifying the rights of, and/or the benefits to, the
holders of Rights. Upon the delivery of a certificate from an appropriate
officer of the Company which states that the proposed supplement or amendment is
in compliance with the terms of this Section 27, 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 Stock. Notwithstanding anything herein to the contrary, this
Agreement may not be amended at a time when the Rights are not redeemable.

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

          Section 29. Determinations and Actions by the Board of Directors, etc.
For all purposes of this Agreement, any calculation of the number of shares of
Common Stock or any other class of capital stock outstanding at any particular
time, including for purposes of determining the particular percentage of such
outstanding shares of Common Stock of which any Person is the Beneficial Owner,
shall be made in accordance with the last sentence of Rule 13d-3(d)(1)(i) of
the General Rules and Regulations under the Exchange Act. The Board of Directors
of the Company shall have the exclusive power and authority to administer this
Agreement and to exercise all rights and powers specifically granted to the
Board or to the Company, or as may be necessary or advisable in the
administration of this Agreement, including, without limitation, the right and
power to (i) interpret the provisions of this Agreement, and (ii) make all
determinations deemed necessary or advisable for the administration of this
Agreement (including a determination to redeem or not redeem the Rights or to
amend the Agreement). All such actions, calculations, interpretations and
determinations (including, for purposes of clause (y) below, all omissions with
respect to the foregoing) which are done or made by the Board in



                                       36

good faith, shall (x) be final, conclusive and binding on the Company, the
Rights Agent, the holders of the Rights and all other parties, and (y) not
subject the Board, or any of the directors on the Board to any liability to the
holders of the Rights.

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

          Section 31. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing the
invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, the right of redemption set forth in Section 23 hereof
shall be reinstated and shall not expire until the close of business on the
tenth Business Day following the date of such determination by the Board of
Directors. Without limiting the foregoing, if any provision requiring a specific
group of Directors of the Company to act is held to by any court of competent
jurisdiction or other authority to be invalid, void or unenforceable, such
determination shall then be made by the Board of Directors of the Company in
accordance with applicable law and the Company's Restated Articles of
Incorporation and By-laws.

          Section 32. Governing Law. This Agreement, each Right and each Rights
Certificate issued hereunder shall be deemed to be a contract made under the
laws of the State of Wisconsin and for all purposes shall be governed by and
construed in accordance with the laws of such State applicable to contracts made
and to be performed entirely within such State.

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

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

                        SYBRON INTERNATIONAL CORPORATION


     Pursuant to Section 180.0602 of the Wisconsin Business Corporation Law


     We, Kenneth F. Yontz, Chairman of the Board, President and Chief Executive
Officer, and R. Jeffrey Harris, Vice President-General Counsel and Secretary,
the undersigned officers of Sybron International Corporation, a corporation
organized and existing under the Wisconsin Business Corporation Law, in
accordance with the provisions of Section 180.0602 thereof, DO HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of Directors by the
Restated Articles of Incorporation of the said Corporation, the said Board of
Directors as of December 11, 2000, adopted the following resolution creating a
series of 2,500,000 shares of Preferred Stock, par value $0.01 per share,
designated as Series A Preferred Stock (of which none of the shares of such
series has been issued):

     RESOLVED, that pursuant to the authority vested in the Board of Directors
of this Corporation in accordance with the provisions of its Restated Articles
of Incorporation, a series of Preferred Stock of the Corporation be and it
hereby is created, and that the designation and amount thereof and the voting
powers, preferences and relative, participating, optional and other special
rights of the shares of such series, and the qualifications, limitations or
restrictions thereof are as follows:

     Section 1. Designation and Amount. The shares of such series shall be
designated as "Series A Preferred Stock" and the number of shares constituting
such series shall be 2,500,000.

     Section 2. Dividends and Distributions.

     (A) The holders of shares of Series A Preferred Stock shall be entitled to
receive, when, as and if declared by the Board of Directors out of funds legally
available for the purpose, quarterly dividends payable in cash on the last
business day of March, June, September and December in each year (each such date
being referred to herein as a "Quarterly Dividend Payment Date"), commencing on
the first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series A Preferred Stock, in an amount per share (rounded
to the nearest




<PAGE>   43



cent) equal to the greater of (a) $1.00 or (b) subject to the provision for
adjustment hereinafter set forth, 100 times the aggregate per share amount of
all cash dividends, and 100 times the aggregate per share amount (payable in
kind) of all non-cash dividends or other distributions other than a dividend
payable in shares of Common Stock or a subdivision of the outstanding shares of
Common Stock (by reclassification or otherwise), declared on the Common Stock,
par value $.01 per share, of the Corporation (the "Common Stock") since the
immediately preceding Quarterly Dividend Payment Date, or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Preferred Stock. In the event the Corporation
shall at any time after December 11, 2000 (the "Rights Dividend Declaration
Date") (i) declare any dividend on Common Stock payable in shares of Common
Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the amount to which holders of shares of Series A Preferred Stock were entitled
immediately prior to such event under clause (b) of the preceding sentence shall
be adjusted by multiplying such amount by a fraction the numerator of which is
the number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     (B) The Corporation shall declare a dividend or distribution on the Series
A Preferred Stock as provided in Paragraph (A) above immediately after it
declares a dividend or distribution on the Common Stock (other than a dividend
payable in shares of Common Stock); provided that, in the event no dividend or
distribution shall have been declared on the Common Stock during the period
between any Quarterly Dividend Payment Date and the next subsequent Quarterly
Dividend Payment Date, a dividend of $1.00 per share on the Series A Preferred
Stock shall nevertheless be payable on such subsequent Quarterly Dividend
Payment Date.

     (C) Dividends shall begin to accrue and be cumulative on outstanding shares
of Series A Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares of Series A 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 Preferred Stock entitled
to receive a quarterly dividend and before such Quarterly Dividend Payment Date,
in either of which events such dividends shall begin to accrue and be cumulative
from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall
not bear interest. Dividends paid on the shares of Series A 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 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.

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

                                       2

<PAGE>   44



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

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

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

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



                                       3
<PAGE>   45

     tors in any default period and during the continuance of such period, the
     number of directors shall not be increased or decreased except by vote of
     the holders of Preferred Stock as herein provided or pursuant to the rights
     of any equity securities ranking senior to or pari passu with the Series A
     Preferred Stock.

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

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

              (v) Immediately upon the expiration of a default period, (x) the
     right of the holders of Preferred Stock as a class to elect directors shall
     cease, (y) the term of any directors elected by the holders of Preferred
     Stock as a class shall terminate, and (z) the number of directors shall be
     such number as may be provided for in the articles of incorporation or
     by-laws irrespective of any increase made pursuant to the provisions of
     Paragraph (C)(ii) of this Section 3 (such number being subject, however,
     to change thereafter in any manner provided by law or in the articles of
     incorpora-



                                       4
<PAGE>   46

     tion or by-laws). Any vacancies in the Board of Directors effected by the
     provisions of clauses (y) and (z) in the preceding sentence may be filled
     by a majority of the remaining directors.

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

          Section 4. Certain Restrictions.

          (A) Whenever quarterly dividends or other dividends or distributions
payable on the Series A 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 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 Preferred Stock;

               (ii) declare or pay dividends on or make any other distributions
     on any shares of stock ranking on a parity (either as to dividends or upon
     liquidation, dissolution or winding up) with the Series A Preferred Stock,
     except dividends paid ratably on the Series A 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 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 Preferred Stock; or

               (iv) purchase or otherwise acquire for consideration any shares
     of Series A Preferred Stock, or any shares of stock ranking on a parity
     with the Series A 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.



                                       5
<PAGE>   47

          (B) The Corporation shall not permit any subsidiary of the Corporation
to purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under Paragraph (A) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

          Section 5. Reacquired Shares. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof. All such
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.

          Section 6. Liquidation, Dissolution or Winding Up. (A) Upon any
liquidation (voluntary or otherwise), dissolution or winding up of the
Corporation, no distribution shall be made to the holders of shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Preferred Stock unless, prior thereto, the holders
of shares of Series A Preferred Stock shall have received an amount equal to
$100 per share of Series A Stock, plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment (the "Series A Liquidation Preference"). Following the payment of
the full amount of the Series A Liquidation Preference, no additional
distributions shall be made to the holders of shares of Series A Preferred Stock
unless, prior thereto, the holders of shares of Common Stock shall have received
an amount per share (the "Common Adjustment") equal to the quotient obtained by
dividing (i) the Series A Liquidation Preference by (ii) 100 (as appropriately
adjusted as set forth in subparagraph (C) below to reflect such events as stock
splits, stock dividends and recapitalizations with respect to the Common Stock)
(such number in clause (ii), the "Adjustment Number"). Following the payment of
the full amount of the Series A Liquidation Preference and the Common Adjustment
in respect of all outstanding shares of Series A Preferred Stock and Common
Stock, respectively, holders of Series A Preferred Stock and holders of shares
of Common Stock shall receive their ratable and proportionate share of the
remaining assets to be distributed in the ratio of the Adjustment Number to 1
with respect to such Preferred Stock and Common Stock, on a per share basis,
respectively.

          (B) In the event, however, that there are not sufficient assets
available to permit payment in full of the Series A Liquidation Preference and
the liquidation preferences of all other series of preferred stock, if any,
which rank on a parity with the Series A Preferred Stock, then such remaining
assets shall be distributed ratably to the holders of such parity shares in
proportion to their respective liquidation preferences. In the event, however,
that there are not sufficient assets available to permit payment in full of the
Common Adjustment, then such remaining assets shall be distributed ratably to
the holders of Common Stock.

          (C) In the event the Corporation shall at any time after the Rights
Dividend Declaration Date (i) declare any dividend on Common Stock payable in
shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
combine the outstanding Common Stock into a smaller number of shares, then in
each such case the Adjustment Number in effect immediately prior to such event
shall be adjusted by multiplying such Adjustment Number by a fraction the


                                       6
<PAGE>   48



numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

          Section 7. Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case the shares of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed in an amount per share (subject to the provision for adjustment
hereinafter set forth) equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time after the Rights Dividend
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the amount set forth in the preceding sentence with respect to the exchange or
change of shares of Series A Preferred Stock shall be adjusted by multiplying
such amount by a fraction the numerator of which is the number of shares of
Common Stock outstanding immediately after such event and the denominator of
which is the number of shares of Common Stock that were outstanding immediately
prior to such event.

          Section 8. Ranking. The Series A Preferred Stock shall rank junior to
all other series of the Corporation's Preferred Stock as to the payment of
dividends and the distribution of assets, unless the terms of any such series
shall provide otherwise.

          Section 9. No Redemption. The shares of Series A Preferred Stock shall
not be redeemable.

          Section 10. Amendment. At any time when any shares of Series A
Preferred Stock are outstanding, neither the Restated Articles of Incorporation
of the Corporation nor this Certificate of Designation shall be amended in any
manner which would materially alter or change the powers, preferences or special
rights of the Series A Preferred Stock so as to affect them adversely without

Bank, a national banking association (the "Rights Agent"), to purchase from the
Company at any time prior to 5:00 P.M. (New York City time) on December 12, 2010
(unless such date is extended prior thereto by the Board of Directors) at the
office or offices of the Rights Agent designated for such purpose, or its
successors as Rights Agent, one one-hundredth of a fully paid, non-assessable
share of Series A Preferred Stock (the "Preferred Stock") of the Company, at a
purchase price of $140 per one one-hundredth of a share (the "Purchase Price"),
upon presentation and surrender of this Rights Certificate with the Form of
Election to Purchase and related Certificate duly executed. The number of Rights
evidenced by this Rights Certificate (and the number of shares which may be
purchased upon exercise thereof) set forth above, and the Purchase Price per
share set forth above, are the number and Purchase Price as of December 12,
2000, based on the Preferred Stock as constituted at such date. The Company
reserves the right to require prior to the occurrence of a Triggering Event (as
such term is defined in the Rights Agreement) that a number of Rights be
exercised so that only whole shares of Preferred Stock will be issued.

     Upon the occurrence of a Section 11(a)(ii) Event (as such term is defined
in the Rights Agreement), if the Rights evidenced by this Rights Certificate are
beneficially owned by (i) an Acquiring Person or an Affiliate or Associate of
any such Acquiring Person (as such terms are defined in the Rights Agreement),
(ii) a transferee of any such Acquiring Person, Associate or Affiliate, or (iii)
under certain circumstances specified in the Rights Agreement, a transferee of a
person who, after such transfer, became an Acquiring Person, or an Affiliate or
Associate of an Acquiring Person, such Rights shall become null and void and no
holder hereof shall have any right with respect to such Rights from and after
the occurrence of such Section 11(a)(ii) Event.

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

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

     This Rights Certificate, with or without other Rights Certificates, upon
surrender at the principal office or offices of the Rights Agent designated for
such purpose, may be exchanged for another Rights Certificate or Rights
Certificates of like tenor and date evidencing Rights entitling the holder to
purchase a like aggregate number of one one-hundredths of a share of Preferred
Stock as the Rights evidenced by the Rights Certificate or

Rights Certificates surrendered shall have entitled such holder to purchase. If
this Rights Certificate shall be exercised in part, the holder shall be entitled
to receive upon surrender hereof another Rights Certificate or Rights
Certificates for the number of whole Rights not exercised.

     Subject to the provisions of the Rights Agreement, the Rights evidenced by
this Certificate may be redeemed by the Company at its option at a redemption
price of $.01 per Right at any time prior to the earlier of the close of
business on (i) the tenth Business Day following the Stock Acquisition Date (as
such time period may be extended pursuant to the Rights Agreement), and (ii) the
Final Expiration Date. In addition, under certain circum stances following the
Stock Acquisition Date, the Rights may be exchanged, in whole or in part, for
shares of the Common Stock, or shares of preferred stock of the Company having
essentially the same value or economic rights as such shares. Immediately upon
the action of the Board of Directors of the Company authorizing any such
exchange, and without any further action or any notice, the Rights (other than
Rights which are not subject to such exchange) will terminate and the Rights
will only enable holders to receive the shares issuable upon such exchange.

     No fractional shares of Preferred Stock will be issued upon the exercise of
any Right or Rights evidenced hereby (other than fractions which are integral
multiples of one one-hundredth of a share of Preferred Stock, which may, at the
election of the Company, be evidenced by depositary receipts), but in lieu
thereof a cash payment will be made, as provided in the Rights Agreement. The
Company, at its election, may require that a number of Rights be exercised so
that only whole shares of Preferred Stock would be issued.

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

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

                          SUMMARY OF RIGHTS TO PURCHASE
                                 PREFERRED STOCK


     As of December 11, 2000, the Board of Directors of Sybron International
Corporation (proposed to be renamed Apogent Technologies Inc.) (the "Company")
declared a dividend distribution of one Right for each outstanding share of
Company Common Stock to stockholders of record at the close of business on
December 12, 2000 (the "Record Date"). Each Right entitles the registered holder
to purchase from the Company a unit consisting of one one-hundredth of a share
(a "Unit") of Series A Preferred Stock, par value $0.01 per share (the "Series A
Preferred Stock"), at a Purchase Price of $140 per Unit, subject to adjustment.
The description and terms of the Rights are set forth in a Rights Agreement (the
"Rights Agreement") between the Company and Fleet National Bank, as Rights
Agent.

     Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Rights Certificates will
be distributed. Subject to certain exceptions specified in the Rights Agreement,
the Rights will separate from the Common Stock and a Distribution Date will
occur upon the earlier of (i) ten business days following a public announcement
that a person or group of affiliated or associated persons (an "Acquiring
Person") has acquired beneficial ownership of 15% or more of the outstanding
shares of Common Stock (the "Stock Acquisition Date"), other than as a result of
repurchases of stock by the Company or certain inadvertent actions by
institutional or certain other stockholders or (ii) 10 business days (or such
later date as the Board shall determine) following the commencement of a tender
offer or exchange offer that would result in a person or group becoming an
Acquiring Person. Until the Distribution Date, (i) the Rights will be evidenced
by the Common Stock certificates and will be transferred with and only with such
Common Stock certificates, (ii) new Common Stock certificates issued after the
Record Date will contain a notation incorporating the Rights Agreement by
reference and (iii) the surrender for transfer of any certificates for Common
Stock outstanding will also constitute the transfer of the Rights associated
with the Common Stock represented by such certificate. Pursuant to the Rights
Agreement, the Company reserves the right to require prior to the occurrence of
a Triggering Event (as defined below) that, upon any exercise of Rights, a
number of Rights be exercised so that only whole shares of Series A Preferred
Stock will be issued.

     The Rights are not exercisable until the Distribution Date and will expire
at 5:00 P.M. (New York City time) on December 12, 2010, unless such date is
extended or the Rights are earlier redeemed or exchanged by the Company as
described below.

<PAGE>   61



     As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to holders of record of the Common Stock as of the close of
business on the Distribution Date and, thereafter, the separate Rights
Certificates alone will represent the Rights. Except as otherwise determined by
the Board of Directors, only shares of Common Stock issued prior to the
Distribution Date will be issued with Rights.

     In the event that a Person becomes an Acquiring Person, except pursuant to
an offer for all outstanding shares of Common Stock which the independent
directors determine to be fair and not inadequate to and to otherwise be in the
best interests of the Company and its stockholders, after receiving advice from
one or more investment banking firms (a "Qualified Offer"), each holder of a
Right will thereafter have the right to receive, upon exercise, Common Stock
(or, in certain circumstances, cash, property or other securities of the
Company) having a value equal to two times the exercise price of the Right.
Notwithstanding any of the foregoing, following the occurrence of the event set
forth in this paragraph, all Rights that are, or (under certain circumstances
specified in the Rights Agreement) were, beneficially owned by any Acquiring
Person will be null and void. However, Rights are not exercisable following the
occurrence of the event set forth above until such time as the Rights are no
longer redeemable by the Company as set forth below.

     For example, at an exercise price of $140 per Right, each Right not owned
by an Acquiring Person (or by certain related parties) following an event set
forth in the preceding paragraph would entitle its holder to purchase $280 worth
of Common Stock (or other consideration, as noted above) for $140. Assuming that
the Common Stock had a per share value of $35 at such time, the holder of each
valid Right would be entitled to purchase 8 shares of Common Stock for $140.

     In the event that, at any time following the Stock Acquisition Date, (i)
the Company engages in a merger or other business combination transaction in
which the Company is not the surviving corporation (other than with an entity
which acquired the shares pursuant to a Qualified Offer), (ii) the Company
engages in a merger or other business combination transaction in which the
Company is the surviving corporation and the Common Stock of the Company is
changed or exchanged, or (iii) 50% or more of the Company's assets, cash flow
or earning power is sold or transferred, each holder of a Right (except Rights
which have previously been voided as set forth above) shall thereafter have the
right to receive, upon exercise, common stock of the acquiring company having a
value equal to two times the exercise price of the Right. The events set forth
in this paragraph and in the second preceding paragraph are referred to as the
"Triggering Events."

     At any time after a person becomes an Acquiring Person and prior to the
acquisition by such person or group of fifty percent (50%) or more of the
outstanding Common Stock, the Board may exchange the Rights (other than Rights
owned by such person or group which have become void), in whole or in part, at
an exchange ratio of one share of Common Stock, or one one-hundredth of a share
of Series A Preferred Stock (or of


                                       2

<PAGE>   62



a share of a class or series of the Company's preferred stock having equivalent
rights, preferences and privileges), per Right (subject to adjustment).

     At any time until ten business days following the Stock Acquisition Date,
the Company may redeem the Rights in whole, but not in part, at a price of $.01
per Right (payable in cash, Common Stock or other consideration deemed
appropriate by the Board of Directors). Immediately upon the action of the Board
of Directors ordering redemption of the Rights, the Rights will terminate and
the only right of the holders of Rights will be to receive the $.01 redemption
price.

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

     Any of the provisions of the Rights Agreement may be amended by the Board
of Directors of the Company prior to the Distribution Date. After the
Distribution Date, the provisions of the Rights Agreement may be amended by the
Board in order to cure any ambiguity, to make changes which do not adversely
affect the interests of holders of Rights, or to shorten or lengthen any time
period under the Rights Agreement. The foregoing notwithstanding, no amendment
may be made at such time as the Rights are not redeemable.

     A copy of the Rights Agreement is being filed with the Securities and
Exchange Commission as an Exhibit to the Company's Registration Statement on
Form 8-A relating to the Rights and its Current Report on Form 8-K dated
December 11, 2000. A copy of the Rights Agreement is available free of charge
from the Rights Agent. This summary description of the Rights does not purport
to be complete and is qualified in its entirety by reference to the Rights
Agreement, which is incorporated herein by reference.
