Item 1.  Description of Securities to be Registered.

                  On August 7, 1998, the Board of Directors of Sybron
Chemicals Inc. (the "Company") adopted a Shareholder Rights Plan, providing
for a distribution of one preferred stock purchase right (a "Right") for each
share of Common Stock, par value $0.01 per share, of the Company (the "Common
Stock"). Each Right entitles the registered holder to purchase from the
Company a unit (a "Unit") consisting of one ten-thousandth of a share of
Series A Junior Participating Preferred Stock, par value $0.01 per share (the
"Preferred Stock"), at a Purchase Price of $150.00 per Unit (the "Purchase
Price"), subject to adjustment. The description and terms of the Rights are
set forth in the Rights Agreement (the "Rights Agreement"), dated as of August
7, 1998, between the Company and BankBoston, N.A., as Rights Agent (the
"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. The Rights will separate from the Common
Stock and a Distribution Date will occur upon the earlier of (i) ten (10) days
following a public announcement that a person or group of affiliated or
associated persons (an "Acquiring Person") has acquired, or obtained the right
to acquire, beneficial ownership of 20% or more of the outstanding shares of
Common Stock (the "Stock Acquisition Date") or (ii) ten (10) business days
following the commencement of a tender offer or exchange offer that would
result in a person or group beneficially owning 20% or more of the outstanding
shares of Common Stock. The definition of Acquiring Person excludes any
Exempted Person (as defined below). 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 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.

                  Any person who, together with all affiliates and associates
of such person, is, on August 7, 1998, the beneficial owner of Common Stock,
options and/or warrants exercisable for shares of Common Stock representing
20% or more of the shares of Common Stock outstanding on such date, will be an
"Exempted Person." In addition, any person who, together with all affiliates
and associates of such person, becomes the beneficial owner of Common Stock,
options and/or warrants exercisable for shares of Common Stock representing
20% or more of the shares of Common Stock then outstanding as a result of a
purchase by the Company or any of its subsidiaries of shares of Common Stock
will also be an "Exempted Person." However, any such person will no longer be
deemed to be an Exempted Person and will be deemed to be an Acquiring Person
if such person, together with all affiliates and associates of such person,
becomes the beneficial owner, at any time after the date such person became
the beneficial owner of 20% or more of the then outstanding shares of Common
Stock, of additional securities representing 1,000 or more shares of Common
Stock, except if such additional securities are acquired (x) pursuant to the
exercise of options or warrants to purchase


                                       2

<PAGE>



Common Stock outstanding and beneficially owned by such person as of the date
such person became the beneficial owner of 20% or more of the then outstanding
shares of Common Stock or as a result of an adjustment to the number of shares
of Common Stock for which such options or warrants are exercisable pursuant to
the terms thereof, or (y) as a result of a stock split, stock dividend or the
like. A purchaser, assignee or transferee of the shares of Common Stock (or
options or warrants exercisable for Common Stock) from an Exempted Person will
not thereby become an Exempted Person, except that a transferee from the
estate of an Exempted Person who receives Common Stock as a bequest or
inheritance from an Exempted Person shall be an Exempted Person so long as
such transferee continues to be the beneficial owner of 20% or more of the
then outstanding shares of Common Stock.

                  The Rights are not exercisable until the Distribution Date
and will expire at the close of business on August 27, 2008 unless earlier
redeemed by the Company as described below. At no time will the Rights have
any voting power.

                  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 an Acquiring Person becomes the beneficial
owner of 20% or more of the then outstanding shares of Common Stock (unless
such acquisition is made pursuant to a tender or exchange offer for all
outstanding shares of the Company, at a price determined by 75% of the
directors of the Company to be fair and otherwise in the best interest of the
Company and its shareholders after receiving advice from one or more
investment banking firms (a "Qualifying 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. The
Exercise Price is the Purchase Price times the number of Units associated with
each Right (initially, one). Notwithstanding any of the foregoing, following
the occurrence of an Acquiring Person becoming such (the "Flip-In Event"), 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 a
Flip-In Event until such time as the Rights are no longer redeemable by the
Company as set forth below.

                  In the event that following the Stock Acquisition Date, (i)
the Company engages in a merger or business combination transaction in which
the Company is not the surviving corporation (other than a merger consummated
pursuant to a Qualifying Offer); (ii) the Company engages in a merger or
business combination transaction in which the Company is the surviving
corporation and the Common Stock is changed or exchanged; or (iii) 50% or more
of the Company's assets 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


                                       3

<PAGE>



receive, upon exercise of the Right, common stock of the acquiring company
having a value equal to two times the Exercise Price of the Right.

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

                  With certain exceptions, no adjustments in the Purchase
Price will be required until cumulative adjustments amount to at least 1% of
the Purchase Price. No fractional Units will be issued and, in lieu thereof,
an adjustment in cash will be made based on the market price of the Preferred
Stock on the last trading date prior to the date of exercise.

                  At any time after the Stock Acquisition Date, the Board of
Directors of the Company may exchange the Rights (other than Rights owned by
an Acquiring Person), in whole or in part, at an exchange ratio of one share
of Common Stock per Right (subject to adjustment). Any such exchange shall
require the concurrence of 75% of the members of the Board of Directors of the
Company then in office.

                  At any time until ten (10) days following the Stock
Acquisition Date, the Company may redeem the Rights in whole, but not in part,
at a price of $0.001 per Right. Under certain circumstances, the decision to
redeem shall require the concurrence of 75% of the members of 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 $0.001 redemption price.

                  Until a Right is exercised, the holder thereof, as such,
will have no rights as a shareholder 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 shareholders or to the Company,
shareholders 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 as set forth above or in the event the Rights
are redeemed.

                  Other than those provisions relating to the principal
economic terms of the Rights, any of the provisions of the Rights Agreement
may be amended by the Board of Directors of the Company (in certain
circumstances, with the concurrence of 75% of the members of the Board of
Directors) prior to the Distribution Date. After the Distribution Date, the
provisions of the Rights Agreement may be amended by the Board (in certain
circumstances, with the concurrence of 75% of the members of the Board of
Directors) in order to cure any ambiguity, to make changes which do not
adversely affect the interests of holders of Rights


                                       4

(excluding the interests of any Acquiring Person), or to shorten or lengthen
any time period under the Rights Agreement; provided, however, that no
amendment to adjust the time period governing redemption shall be made at such
time as the Rights are not redeemable.

                  This Summary of 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.

                  RIGHTS AGREEMENT, dated as of August 7, 1998 (the
"Agreement"), between Sybron Chemicals Inc., a Delaware corporation (the
"Company"), and BankBoston, N.A. (the "Rights Agent").

                             W I T N E S S E T H :

                  WHEREAS, on August 7, 1998 (the "Rights Dividend Declaration
Date"), the Board of Directors of the Company authorized and declared a
dividend distribution of one Right ("Rights") for each share of Common Stock,
par value $0.01 per share, of the Company (the "Common Stock") outstanding at
the close of business on August 27, 1998 (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 issued between the Record Date (whether originally issued or
delivered from the Company's treasury) and the Distribution Date (as defined
in Section 3 hereof), each Right initially representing the right to purchase
one ten-thousandth of a share (a "Unit") of Series A Junior Participating
Preferred Stock (the "Preferred Stock") of the Company 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.

                  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 20% 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, (iv) any Person organized, appointed or established by the
Company for or pursuant to the terms of any such plan, or (v) any Exempted
Person.

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

                        (c) 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


                                       1

<PAGE>



immediately or only after the passage of time or the occurrence of an event)
pursuant to any agreement, arrangement or understanding (whether or not in
writing) or upon the exercise of conversion rights, exchange rights, rights,
warrants or options, or otherwise; provided, however, that 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, (C)
securities issuable upon exercise of Rights from and after the occurrence of a
Triggering Event, which Rights were acquired by such Person or any of such
Person's Affiliates or Associates prior to the Distribution Date or pursuant
to Section 3(a) or Section 22 hereof (the "Original Rights") or pursuant to
Section 11(i) hereof in connection with an adjustment made with respect to any
Original Rights, or (D) securities issued or issuable pursuant to any employee
benefit plan of the Company or any Subsidiary of the Company or any employment
agreement, arrangement or other understanding between the Company or any
Subsidiary of the Company and any Person or any of such Person's Affiliates or
Associates; or

                              (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 (A) an agreement, arrangement or understanding to vote such
security if such agreement, arrangement or understanding: (1) 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
(2) is not also then reportable by such Person on Schedule 13D under the
Exchange Act (or any comparable or successor report), or (B) securities issued

Subsidiary of the Company or any employment agreement, arrangement or other
understanding between the Company or any Subsidiary of the Company and any

                              (iii) which are beneficially owned, directly or

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 (c)) or
disposing of any voting securities of the Company;

provided, however, that nothing in this paragraph (c) 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 (40) days after the date of such acquisition; and
provided, further, however, that any stockholder of the Company, with
Affiliates, Associates or

other Person(s) who may be deemed representatives of it serving as director(s)
or officer(s) of the Company, shall not be deemed to beneficially own
securities held by other Persons as a result of (i) Persons affiliated or
otherwise associated with such stockholder serving as director(s) or
officer(s) or taking any action in connection therewith, (ii) discussing the
status of its shares with the Company or other stockholders of the Company
similarly situated or (iii) voting or acting in a manner similar to other
stockholder(s) similarly situated, absent a specific finding by the Board of
Directors of an express agreement among such stockholders to act in concert
with one another as stockholders so as to cause, in the good faith judgment of
the Board of Directors, each such stockholder to be the Beneficial Owner of
the shares held by the other stockholder(s).

stock of such Person with the greatest voting power, or the equity securities
or other equity interest having power to control or direct the management, of

                  Section 3.        Issue of Rights Certificates.

                              (a) Until the earlier of (i) the close of
business on the tenth day after the Stock Acquisition Date (or, if the tenth
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 of Directors of the Company
shall determine without reference to Section 26 hereof) after the date that a
tender or exchange offer by any Person (other than any Exempted Person, the
Company, any Subsidiary of the Company, any employee benefit plan of the
Company or of any Subsidiary of the Company, or any Person 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 be the Beneficial Owner of 20% or more
of the shares of Common Stock then outstanding (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 forms of Exhibit B hereto (the "Rights
Certificates"), evidencing one right for each share of Common Stock so held,
subject to adjustment as provided herein. In the event that an adjustment in
the number of Rights per share of Common Stock has been made pursuant to
Section 11(p) hereof, at the time of distribution of the Rights Certificates,
the Company shall make the necessary and appropriate rounding adjustments (in
accordance with Section 14(a) hereof) so that Rights Certificates representing
only whole numbers of Rights are distributed and cash is paid in lieu of any
fractional Rights. As of and after the Distribution Date, the Rights will be
evidenced solely by such Rights Certificates.

                              (b) As promptly as practicable following the
Record Date, the Company will send a copy of a Summary of Rights, in
substantially the form attached hereto as Exhibit C (the "Summary of Rights"),
by first-class, postage prepaid mail, to each record holder of the Common
Stock as of the close of business on the Record Date, at the address of such
holder shown on the records of the Company. With respect to certificates for
the Common Stock outstanding as of the Record Date, until the Distribution
Date, the Rights will be evidenced by such 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 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.



                                       5

<PAGE>



                              (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 Chemicals Inc. (the "Company") and BankBoston, N.A. (the
"Rights Agent"), dated as of August 7, 1998 (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 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 forms 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
ten-thousandths of a share of Preferred Stock as shall be set forth therein at
the price set forth therein (such exercise price per one ten-thousandth 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) 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,


                                       6

<PAGE>



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
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 such Agreement.

                  Section 5. Countersignature and Registration.

                              (a) The Rights Certificates shall be executed on
behalf of the Company by its Chairman of the Board, its President or any 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 shall keep or cause to be kept, at its principal office or offices
designated as the appropriate place for surrender of Rights Certificates upon
exercise or transfer, books for registration and transfer of the Rights
Certificates issued hereunder. Such books shall show the names and addresses
of the respective holders of the Rights Certificates, the number of Rights
evidenced on its face by each of the Rights Certificates and the date of each
of the Rights Certificates.

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

                              (a) Subject to the provisions of Section 4(b),
Section 7(e) and Section 14 hereof, at any time after the close of business on
the Distribution Date, and at or prior to the close of business on the
Expiration Date, any Rights Certificate or Certificates may be transferred,
split up, combined or exchanged for another Rights Certificate or
Certificates, entitling the registered holder to purchase a like number of one
ten-thousandths of a share of Preferred Stock (or, following a Triggering
Event, Common Stock, other securities, cash or other assets, as the case may
be) as the Rights Certificate or Certificates surrendered then entitled such
holder (or former holder in the case of a transfer) to purchase. Any
registered holder desiring to transfer, split up, combine or exchange any
Rights Certificate or Certificates shall make such request in writing
delivered to the Rights Agent, and shall surrender the Rights Certificate or
Certificates to be transferred, split up, combined or exchanged at the
principal office or offices of the Rights Agent designated for such purpose.
Neither the Rights Agent nor the Company shall be obligated to take any action
whatsoever with respect to the transfer of any such surrendered Rights
Certificate until the registered holder shall have completed and signed the
certificate contained in the form of assignment on the reverse side of such
Rights Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request. Thereupon the
Rights Agent shall, subject to Section 4(b), Section 7(e) and Section 14
hereof, countersign and deliver to the Person entitled thereto a Rights
Certificate or Rights Certificates, as the case may be, as so requested. The
Company may require payment of a 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 7. Exercise of Rights; Purchase Price; Expiration
Date of Rights.

                              (a) Subject to Section 7(e) hereof, the
registered holder of any Rights Certificate may exercise the Rights evidenced
thereby (except as otherwise provided herein including, without limitation,
the restrictions on exercisability set forth in Section 9(c), Section
11(a)(iii) and Section 23(a) hereof) in whole or in part at any time after the
Distribution Date upon surrender of the Rights Certificate, with the form of
election to purchase and the 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


                                       8

<PAGE>



Price with respect to the total number of one ten-thousandths of a share of
Preferred Stock (or other securities, cash or other assets, as the case may
be) as to which such surrendered Rights are then exercisable, at or prior to
the earlier of (i) the close of business on August 27, 2008 (the "Final
Expiration Date"), or (ii) the time at which the Rights are redeemed as
provided in Section 23 hereof (the earlier of (i) and (ii) being herein
referred to as the "Expiration Date").

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

                              (c) Upon receipt of a Rights Certificate
representing exercisable Rights, with the form of election to purchase and the
certificate duly executed, accompanied by payment, with respect to each Right
so exercised, of the Purchase Price per one ten-thousandth of 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
ten-thousandths 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 ten-thousandths 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 shall 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 would 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 equivalent to the Rights remaining
unexercised shall be issued by the Rights Agent and delivered


                                       9

<PAGE>



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 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 other Person as a result of its failure to make any
determinations with respect to an Acquiring Person or 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 canceled form, or, if surrendered to the Rights Agent,
shall be canceled by it, and no Rights Certificates shall be issued in lieu
thereof except as expressly permitted by any of the provisions of this
Agreement. The Company shall deliver to the Rights Agent for cancellation and
retirement, and the Rights Agent shall so cancel and retire, any other Rights
Certificate purchased or acquired by the Company otherwise than upon the
exercise thereof. The Rights Agent shall deliver all canceled Rights
Certificates to the Company, or shall, at the written request of the Company,
destroy such canceled Rights Certificates, and in such case shall deliver a
certificate of destruction thereof to the Company.

                  Section 9. Reservation and Availability of Capital Stock.

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

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

                              (c) The Company shall use its best efforts to
(i) file, as soon as practicable following the earliest date after the first
occurrence of a Section 11(a)(ii) Event on which the consideration to be
delivered by the Company upon exercise of the Rights has been determined in
accordance with Section 11(a)(iii) hereof, a registration statement under the
Securities Act of 1933 (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 is no longer in effect. 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
ten-thousandths of a share of Preferred Stock (and,


                                      11

<PAGE>



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

                  Section 10. Preferred Stock Record Date. Each Person in
whose name any certificate for a number of one ten-thousandths 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 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 (other than an
Exempted Person, the Company, any Subsidiary of the Company, any employee
benefit plan of the Company or of any Subsidiary of the Company, or any Person
organized, appointed or established by the Company for or pursuant to the
terms of any such plan), alone or together with its Affiliates and Associates,
shall, at any time after the Rights Dividend Declaration Date, become the
Beneficial Owner of 20% or more of the shares of Common Stock then
outstanding, unless the event causing the 20% threshold to be crossed 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 75% of the members of the Board of Directors of the Company, after
receiving advice from one or more investment banking firms, to be (a) at a
price which is fair to stockholders (taking into account all factors which
such members of the Board 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 (hereinafter a "Qualifying
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 ten-thousandths 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 ten-thousandths 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


                                      13

<PAGE>



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 are authorized by the Company's Certificate of
Incorporation but not outstanding or reserved for issuance for purposes other
than upon exercise of the Rights are not sufficient to permit the exercise in
full of the Rights 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 of Directors of
the Company 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 of Directors of the Company 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-day period set forth above may be extended to the extent necessary, but
not more than ninety (90) days after the Section 11(a)(ii) Trigger Date, in
order that the Company may seek stockholder approval for the authorization of
such additional shares (such thirty-day period, as it may be extended, is
herein called the "Substitution Period"). To the extent that action is to 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 stockholder 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
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


                                      14

<PAGE>



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, 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 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


                                      15

<PAGE>



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 high closing bid and low asked prices, regular way, in either
case as reported by the American Stock Exchange ("AMEX") or, if the shares of
such Common Stock are not included for quotation on the AMEX, 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 such Common Stock are listed or admitted to trading or, if the
shares of such 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 NASDAQ or such other system then in use, or, if on any such
date the shares of such 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 such Common Stock selected by the Board of
Directors of the Company. If on any such date no market maker is making a
market in such 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 (which,
for purposes of this Agreement, shall include the NNM and the NASDAQ Stock
Market's SmallCap Market) on which the shares of Common Stock are listed or
admitted to trading is open for the transaction of


                                      16

<PAGE>



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 10,000 (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 of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent and shall be conclusive for all purposes. For all purposes of this
Agreement, the Current Market Price of a Unit shall be equal to the Current
Market Price of one share of Preferred Stock divided by 10,000.

                            (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 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-hundred 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 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 ten-thousandths 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 ten-thousandths of a share of Preferred Stock (calculated
to the nearest one-ten millionth) obtained by (i) multiplying (x) the number
of one ten-thousandths 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 ten-thousandths 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 ten-thousandths 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
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.

<PAGE>



                            (j) Irrespective of any adjustment or change in
the Purchase Price or the number of one ten-thousandths 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 ten-thousandth of a share and the number of one
ten-thousandths 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 ten-thousandths 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 ten-
thousandths 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 ten-thousandths 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 ten-thousandths
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 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


                                      19

<PAGE>



more transactions each of which complies with Section 11(o) hereof), if (x) at
the time of or immediately after such consolidation, merger or sale there are
any rights, warrants or other instruments or securities outstanding or
agreements in effect which would substantially diminish or otherwise eliminate
the benefits intended to be afforded by the Rights or (y) prior to,
simultaneously with or immediately after such consolidation, merger or sale,
the stockholders of the Person who constitutes, or would constitute, the
"Principal Party" for purposes of Section 13(a) hereof shall have received a
distribution of Rights previously owned by such Person or any of its
Affiliates and Associates.

                            (o) The Company covenants and agrees that, after
the Distribution Date, it will not, except as permitted by Section 23 or
Section 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) mail a brief summary thereof to each holder of a Rights
Certificate (or, if prior to the Distribution Date, to each holder of a
certificate representing shares of Common Stock) in accordance with Section 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 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


                                                        20

(other than a Subsidiary of the Company in a transaction which complies with
Section 11(o) hereof), and the Company shall not be the continuing or
surviving corporation of such consolidation or merger, (y) any Person (other
than a Subsidiary of the Company in a transaction which complies with Section
11(o) hereof) shall consolidate with, or merge with or into, the Company, and
the Company shall be the continuing or surviving corporation of such
consolidation or merger and, in connection with such consolidation or merger,
all or part of the outstanding shares of Common Stock shall be changed into or
exchanged for stock or other securities of any other Person or cash or any
other property, or (z) the Company shall sell or otherwise transfer (or one or
more of its Subsidiaries shall sell or otherwise transfer), in one transaction
or a series of related transactions, assets or earning power aggregating more
than 50% of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to any Person or 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
ten-thousandths 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 ten-thousandths of a
share for which a Right was exercisable immediately prior to the first
occurrence of a Section 11(a)(ii) Event by the Purchase Price in effect
immediately prior to such first occurrence), and dividing that product (which,
following the first occurrence of a Section 13 Event, shall be referred to as
the "Purchase Price" for each Right and for all purposes of this Agreement) by
(2) 50% of the Current Market Price (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 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 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-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 Stocks of two or more of which are and
have been so registered, "Principal Party" shall refer to whichever of such
Persons is the issuer of the Common Stock having the greatest aggregate market
value.

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

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

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

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 Qualifying Offer (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, there shall be paid to
the registered holders of the Rights Certificates with regard to which such
fractional Rights would otherwise be issuable, an amount in cash equal to the
same fraction of the current market value of a whole Right. For purposes of
this Section 14(a), the current market value of a whole Right shall be the
closing price of the Rights for the Trading Day immediately prior to the date
on which such fractional Rights would have been otherwise issuable. The
closing price of the Rights for any day shall be the last sale price, regular
way, or, in case no such sale takes place on such day, the average of the
closing high bid and low asked prices, regular way, in either case as reported
by the AMEX or, if the Rights are not included for quotation on the AMEX, 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 ten-thousandth 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 ten- thousandth of a share of Preferred Stock). In lieu of fractional
shares of Preferred Stock that are not integral multiples of one
ten-thousandth 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 ten- thousandth of a share of Preferred Stock.
For purposes of this Section 14(b), the current market value of one
ten-


                                      23

<PAGE>

thousandth of a share of Preferred Stock shall be one ten-thousandth 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 (1) share of Common Stock shall be the closing price of
one (1) share of Common Stock (as determined pursuant to Section 11(d)(i)
hereof) for the Trading Day immediately prior to the date of such exercise.

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

                  Section 15. Rights of Action. All rights of action in
respect of this Agreement are vested in the respective registered holders of
the Rights Certificates (and, prior to the Distribution Date, the registered
holders of the Common Stock); and any registered holder of any Rights
Certificate (or, prior to the Distribution Date, of the Common Stock), without
the consent of the Rights Agent or of the holder of any other Rights
Certificate (or, prior to the Distribution Date, of the Common Stock), may, in
such holder's own behalf and for such holder's own benefit, enforce, and may
institute and maintain any suit, action or proceeding against the Company to
enforce, or otherwise act in respect of, such holder's 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


                                      24

<PAGE>



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 ten-thousandths 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 24 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


                                      25

<PAGE>



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 or 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; provided,
however, that such corporation would be eligible for appointment as a
successor Rights Agent under the provisions of Section 21 hereof. In case at
the time such successor Rights Agent shall succeed to the agency created by
this Agreement, any of the Rights Certificates shall have been countersigned
but not delivered, any such successor Rights Agent may adopt the
countersignature of 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:



                                      26

<PAGE>



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

                            (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 or Section 13 hereof or responsible for the
manner, method or amount of any such adjustment or the ascertaining of the
existence of facts that would require any such adjustment (except with respect
to the exercise of Rights evidenced by Rights Certificates after actual notice
of any such adjustment); nor shall it by any act hereunder be deemed to make
any representation or warranty as to the authorization or reservation of any
shares of Common Stock or Preferred Stock to be issued pursuant to this
Agreement or any Rights Certificate or as to whether any shares of Common
Stock or Preferred Stock will, when so issued, be validly authorized and
issued, fully paid and nonassessable.

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

                            (g) The Rights Agent is hereby authorized and
directed to accept instructions with respect to the performance of its duties
hereunder from the Chairman of the Board, the President, any Vice President,
the Secretary, any Assistant Secretary, the Treasurer or any Assistant
Treasurer of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and it shall not be liable for any
action taken 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, 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 of transfer without
first consulting with the Company.

                  Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon thirty (30) days' notice in writing mailed to the Company, and
to each transfer agent of the Common Stock and Preferred Stock, by registered
or certified mail, and to the holders of the Rights Certificates by
first-class mail. The Company may, in its sole discretion, remove the Rights
Agent or any successor Rights Agent upon thirty (30) days' notice in writing,
mailed to the Rights Agent or successor Rights Agent, as the case may be, and
to each transfer agent of the Common Stock and Preferred Stock, by registered
or certified mail, and to the holders of the Rights Certificates by
first-class mail. If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent. If the Company


                                      28

<PAGE>



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 corporation organized
and doing business under the laws of the United States or of any state of the
United States, in good standing, which is authorized under such laws to
exercise corporate trust powers and is subject to supervision or examination
by federal or state authority and which has at the time of its appointment as
Rights Agent a combined capital and surplus of at least $100,000,000. After
appointment, the successor Rights Agent shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally named as
Rights Agent without further act or deed; but the predecessor Rights Agent
shall deliver and transfer to the successor Rights Agent any property at the
time held by it hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose. Not later than the
effective date of any such appointment, the Company shall file notice thereof
in writing with the predecessor Rights Agent and each transfer agent of the
Common Stock and the Preferred Stock, and mail a notice thereof in writing to
the registered holders of the Rights Certificates. Failure to give any notice
provided for in this Section 21, however, or any defect therein, shall not
affect the legality or validity of the resignation or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

                  Section 22. Issuance of New Rights Certificates.
Notwithstanding any of the provisions of this Agreement or of the Rights to
the contrary, the Company may, at its option, issue new Rights Certificates
evidencing Rights in such form as may be approved by its Board 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 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 twentieth day following the Record Date), or (ii) the Final
Expiration Date, redeem all but not less than all the then outstanding Rights
at a redemption price of $0.001 per Right, as such amount may be appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such redemption price being hereinafter
referred to as the "Redemption Price"); provided, however, if the Board of
Directors of the Company authorizes redemption of the Rights in either of the
circumstances set forth in clauses (i) and (ii) below, such authorization
shall require the approval of at least 75% of the members of the Board of
Directors then in office: (i) such authorization occurs on or after the time a
Person becomes an Acquiring Person, or (ii) such authorization occurs (A) on
or after the date of a change (resulting from a proxy or consent solicitation
or an action by written consent of stockholders, whether or not made pursuant
to, and in accordance with, the applicable provisions of the General Rules and
Regulations under the Exchange Act) in a majority of the directors in office
at the commencement of such solicitation or action by written consent, or (B)
prior to such written consent, if any Person who is a participant in such
solicitation, or who signed such consent, has stated (or, if upon the
commencement of such solicitation, a majority of the members of the Board of
Directors of the Company has determined in good faith) that such Person (or
any of its Affiliates or Associates) intends to take, or may consider taking,
any action which would result in such Person becoming an Acquiring Person or
which would cause the occurrence of a Triggering Event unless, concurrent with
such solicitation, such Person (or one or more of its Affiliates or
Associates) is making a cash tender offer pursuant to a Schedule 14D-1 (or any
successor form) filed with the Securities and Exchange Commission for all
outstanding shares of Common Stock not beneficially owned by such Person (or
by its Affiliates or Associates). 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.

                            (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


                                      30

<PAGE>



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.       Notice of Certain Events.

                            (a) In case the Company shall propose, at any time
after the Distribution Date, (i) to pay any dividend payable in stock of any
class to the holders of Preferred Stock or to make any other distribution to
the holders of Preferred Stock (other than a regular quarterly cash dividend
out of earnings or retained earnings of the Company), or (ii) to offer to the
holders of Preferred Stock rights or warrants to subscribe for or to purchase
any additional shares of Preferred Stock or shares of stock of any class or
any other securities, rights or options, or (iii) to effect any
reclassification of its Preferred Stock (other than a reclassification
involving only the subdivision of outstanding shares of Preferred Stock), or
(iv) to effect any consolidation or merger into or with any other Person
(other than a Subsidiary of the Company in a transaction which complies with
Section 11(o) hereof), or to effect any sale or other transfer (or to permit
one or more of its Subsidiaries to effect any sale or other transfer), in one
transaction or a series of related transactions, of more than 50% of the
assets or earning power of the Company and its Subsidiaries (taken as a whole)
to any other Person or Persons (other than the Company and/or any of its
Subsidiaries in one or more transactions each of which complies with Section
11(o) hereof), or (v) to effect the liquidation, dissolution or winding up of
the Company, then, in each such case, the Company shall give to each holder of
a Rights Certificate, to the extent feasible and in accordance with Section 25
hereof, a notice of such proposed action, which shall specify the record date
for the purposes of such stock dividend, distribution of rights or warrants,
or the date on which such reclassification, consolidation, merger, sale,
transfer, liquidation, dissolution, or winding up is to take place and the
date of participation therein by the holders of the shares of Preferred Stock,
if any such date is to be fixed, and such notice shall be so given in the case
of any action covered by clause (i) or (ii) above at least twenty (20) days
prior to the record date for determining holders of the shares of Preferred
Stock for purposes of such action, and in the case of any such other action,
at least twenty (20) days prior to the date of the taking of such proposed
action or the date of participation therein by the holders of the shares of
Preferred Stock whichever shall be the earlier.

                            (b) In case any of the events set forth in Section
11(a)(ii) hereof shall occur, then, in any such case, (i) the Company shall as
soon as practicable thereafter give to each holder of a Rights Certificate, to
the extent feasible and in accordance with Section 25 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 25. 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


                                      31

Company shall be sufficiently given or made if sent by first-class mail,
postage prepaid, addressed (until another address is filed in writing with the
Rights Agent) as follows:

                           Attention:  President

Subject to the provisions of Section 21, any notice or demand authorized by
this Agreement to be given or made by the Company or by the holder of any
Rights Certificate to or on the Rights Agent shall be sufficiently given or
made if sent by first-class mail, postage prepaid, addressed (until another
address is filed in writing with the Company) as follows:

                           Attention:  Client Administration

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

                  Section 26. Supplements and Amendments. Prior to the
Distribution Date and subject to the penultimate sentence of this Section 26,
the Company and the Rights Agent shall, if the Company so directs, supplement
or amend any provision of this Agreement without the approval of any holders
of certificates representing shares of Common Stock; provided, however, that
following the first occurrence of an event set forth in clauses (i) and (ii)
of the first proviso of Section 23(a) hereof, any supplement or amendment of
this Agreement which shortens or lengthens any time period hereunder or
adversely affects the interests of the holders of Rights Certificates (other
than an Acquiring Person or an Affiliate or Associate of an Acquiring Person)
shall require the approval of at least 75% of the members of the Board of
Directors then in office. From and after the Distribution Date and subject to
the penultimate sentence of this Section 26, the Company and the Rights Agent
shall, if the Company so directs, supplement or amend this Agreement without
the approval of any holders of Rights Certificates in order (i) to cure any
ambiguity, (ii) to correct or supplement any provision contained herein which
may be defective or inconsistent with any other provisions herein, (iii) to
shorten or lengthen any time period hereunder (which lengthening or
shortening, following the first occurrence of an event set forth in clauses
(i) and (ii) of the first proviso to Section 23(a) hereof, shall require the
approval of at least 75% of the members of the Board of Directors then in
office), 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


                                      32

<PAGE>



(other than an Acquiring Person or an Affiliate or Associate of an Acquiring
Person); provided, however, this Agreement may not be supplemented or amended
to lengthen, whether prior to, from or after the Distribution Date, pursuant
to clause (iii) of this sentence or otherwise, (A) a time period relating to
when the Rights may be redeemed at such time as the Rights are not then
redeemable, or (B) any other time period unless such lengthening is for the
purpose of protecting, enhancing or clarifying the rights of, and/or the
benefits to, the holders of Rights. 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 26, the Rights
Agent shall execute such supplement or amendment. Notwithstanding anything
contained in this Agreement to the contrary, no supplement or amendment shall
be made which changes the Redemption Price, the Final Expiration Date, the
Purchase Price or the number of one ten-thousandths of a share of Preferred
Stock for which a Right is exercisable. Prior to the Distribution Date, the
interests of the holders of Rights shall be deemed coincident with the
interests of the holders of Common Stock.

                  Section 27.       Exchange.

                            (a)   (i) The Company may, at its option, at any
time after the Stock Acquisition Date, upon resolution by the Board of
Directors of the Company, 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 of this Agreement (such exchange ratio being hereinafter
referred to as the "Section 27(a) Exchange Ratio"). Notwithstanding the
foregoing, the Company may not effect such exchange at any time after any
Acquiring Person becomes the Beneficial Owner of 50% or more of the shares of
Common Stock then outstanding.

                                   (ii) Notwithstanding anything contained in
this Section 27(a) to the contrary, the Company may not exchange any Rights
pursuant to this Section 27(a) unless such exchange is approved by at least
75% of the members of the Board of Directors then in office.

                            (b) Immediately upon the action of the Board of
Directors of the Company ordering the exchange of any Rights pursuant to
paragraph (a) of this Section 27 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 Section 27(a) 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


                                      33

<PAGE>



exchange will state the method by which the exchange of the shares of Common
Stock for Rights will be effected and, in the event of any partial exchange,
the number of Rights which will be exchanged. Any partial exchange shall be
effected pro rata based on the number of Rights (other than Rights which have
become void pursuant to the provisions of Section 7(e) hereof) held by each
holder of Rights.

                            (c) In the event that there shall not be
sufficient 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 27, the Company shall make adequate provision to substitute, to
the extent that there are insufficient shares of Common Stock available (1)
cash, (2) other equity securities of the Company, (3) debt securities of the
Company, (4) other assets or (5) any combination of the foregoing, having an
aggregate value per Right equal to the then current per share market price
(determined pursuant to Section 11(d) hereof) of the Common Stock multiplied
by the Section 27(a) Exchange Ratio. To the extent that the Company determined
that any such substitution must be made, the Company shall provide, subject to
Section 7(e) hereof, that such substitution shall apply uniformly to all
outstanding Rights.

                            (d) 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, the Company shall pay 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 paragraph (d), 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) hereof) for the Trading Day
immediately prior to the date of the exchange pursuant to this Section 27.

                  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 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 (subject to, where specifically provided for herein, the
requirement of approval by at least 75% of the members of the Board of
Directors then in office) shall have the exclusive power and authority to
administer this Agreement and to exercise all rights and powers specifically
granted to the Board (subject to, where specifically provided for herein, the
requirement of approval by at least 75% of the members of the Board of
Directors then in office) 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


                                      34

<PAGE>



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 (subject
to, where specifically provided for herein, the requirement of approval by at
least 75% of the members of the Board of Directors then in office) in good
faith, shall (x) be final, conclusive and binding on the Company, the Rights
Agent, the holders of the Rights and all other parties, and (y) not subject
the Board 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 twentieth day following the date of
such determination by the Board of Directors.

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

                  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.

                  Pursuant to Section 151 of the General Corporation Law of
the State of Delaware, the undersigned officers of Sybron Chemicals Inc., a
corporation organized and existing under the General Corporation Law of the
State of Delaware (the "Corporation"), in accordance with the provisions of
Section 103 thereof, DO HEREBY CERTIFY:

                  That pursuant to the authority conferred upon the Board of
Directors by the Certificate of Incorporation of the Corporation, as amended,
the Board of Directors on August 7, 1998 adopted the following resolution
creating a series of 2,000 shares of Preferred Stock designated as Series A
Junior Participating Preferred Stock:

                  RESOLVED, that pursuant to the authority vested in the Board
of Directors of this Corporation in accordance with the provisions of its
Restated Certificate 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 Junior Participating Preferred Stock" and the
number of shares constituting such series shall be 2,000.

                  Section 2.        Dividends and Distributions.

                            (A) The holders of shares of Series A Junior
Participating Preferred Stock shall be entitled to receive, when, as and if
declared by the Board of Directors out of funds legally available for the
purpose, quarterly dividends payable in cash on the last 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 Junior Participating Preferred Stock, in an amount per share
(rounded to the nearest cent) equal to the greater of (a) $0.001 or (b)
subject to the provision for adjustment hereinafter set forth, 10,000 times
the aggregate per share amount of all cash dividends, and 10,000 times the
aggregate per share amount (payable in kind) of all non-cash dividends or
other distributions other than a dividend


                                      A-1

<PAGE>



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 $0.01 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 Junior Participating Preferred
Stock. In the event the Corporation shall at any time after August 27, 1998
(the "Rights Declaration Date") (i) declare any dividend on Common Stock
payable in shares of Common Stock, (ii) subdivide the outstanding Common
Stock, or (iii) combine the outstanding Common Stock into a smaller number of
shares, then in each such case the amount to which holders of shares of Series
A Junior Participating Preferred Stock were entitled immediately prior to such
event under clause (b) of the preceding sentence shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                            (B) The Corporation shall declare a dividend or
distribution on the Series A Junior Participating Preferred Stock as provided
in Paragraph (A) above immediately after it declares a dividend or
distribution on the Common Stock (other than a dividend payable in shares of
Common Stock); provided that, in the event no dividend or distribution shall
have been declared on the Common Stock during the period between any Quarterly
Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date,
a dividend of $0.001 per share on the Series A Junior Participating Preferred
Stock shall nevertheless be payable on such subsequent Quarterly Dividend
Payment Date.

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

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


                                      A-2

<PAGE>



                            (A) Subject to the provision for adjustment
hereinafter set forth, each share of Series A Junior Participating Preferred
Stock shall entitle the holder thereof to a number of votes, if any, on all
matters submitted to a vote of the holders of Common Stock equal to the
product of 10,000 times the number of votes to which each share of Common
Stock shall entitle the holder thereof. In the event the Corporation shall at
any time after the Rights Declaration Date (i) declare any dividend on Common
Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common
Stock, or (iii) combine the outstanding Common Stock into a smaller number of
shares, then in each such case the number of votes per share to which holders
of shares of Series A Junior Participating Preferred Stock were entitled
immediately prior to such event shall be adjusted by multiplying such number
by a fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to
such event.

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

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

                                   (ii) During any default period, such voting
right of the holders of Series A Junior Participating Preferred Stock may be
exercised initially at a special meeting called pursuant to subparagraph (iii)
of this Section 3(C) or at any annual meeting of stockholders, and thereafter
at annual meetings of stockholders, provided that such voting right shall not
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.


                                      A-3

<PAGE>



After the holders of the Preferred Stock shall have exercised their right to
elect Directors in any default period and during the continuance of such
period, the number of Directors shall not be increased or decreased except by
vote of the holders of Preferred Stock as herein provided or pursuant to the
rights of any equity securities ranking senior to or pari passu with the
Series A Junior Participating 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 such holder at such
holder's last address as the same appears on the books of the Corporation.
Such meeting shall be called for a time not earlier than twenty (20) days and
not later than sixty (60) days after such order or request, or in default of
the calling of such meeting within sixty (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 sixty (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 Restated
Certificate of Incorporation or By-laws of the Corporation 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 Certificate of Incorporation or By-laws of the


                                      A-4

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

                  Section 4.        Certain Restrictions.

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

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

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

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

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

<PAGE>



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

                  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 Junior Participating
Preferred Stock unless, prior thereto, the holders of shares of Series A
Junior Participating Preferred Stock shall have received an amount equal to
$1,500,000 per share of Series A Junior Participating Preferred 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 Junior Participating 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) 10,000 (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 Junior Participating Preferred Stock and Common Stock, respectively,
holders of Series A Junior Participating 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
one 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 (either as to dividends or
upon liquidation, dissolution or winding up) with the Series A Junior
Participating 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 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 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 Junior Participating Preferred Stock shall at
the same time be similarly exchanged or changed in an amount per share
(subject to the provision for adjustment hereinafter set forth) equal to
10,000 times the aggregate amount of stock, securities, cash and/or any other
property (payable in kind), as the case may be, into which or for which each
share of Common Stock is changed or exchanged. In the event the Corporation
shall at any time after the Rights Declaration Date (i) declare any dividend
on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock, or (iii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the amount set forth in the
preceding sentence with respect to the exchange or change of shares of Series
A Junior Participating Preferred Stock shall be adjusted by multiplying such
amount by a fraction the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior
to such event.

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

                  Section 9. Amendment. The Certificate of Incorporation of
the Corporation shall not be further amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Series A Junior Participating Preferred Stock so as to affect them adversely
without the affirmative vote of the holders of a majority or more of the
outstanding shares of Series A Junior Participating Preferred Stock, voting
separately as a class.

                  Section 10. Fractional Shares. Series A Junior Participating
Preferred Stock may be issued in fractions of a share which shall entitle the
holder, in proportion to such holders fractional shares, to exercise voting
rights, receive dividends, participate in distributions and to have the
benefit of all other rights of holders of Series A Junior Participating
Preferred Stock.

Agreement), and (ii) the Final Expiration Date. In addition, 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


                                      B-2

<PAGE>



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. Under certain
circumstances set forth in the Rights Agreement, the decision to redeem the
Rights shall require the approval of at least 75% of the directors of the
Company then in office.

                  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 ten-thousandth 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.

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

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

                                                                     Exhibit C


                         SUMMARY OF RIGHTS TO PURCHASE
                 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

                  On August 7, 1998, the Board of Directors of Sybron
Chemicals Inc. (the "Company") adopted a Stockholder Rights Plan, providing
that one Right (a "Right") shall be attached to each share of common stock,
par value $0.01 per share, of the Company (the "Common Stock"). Each Right
entitles the registered holder to purchase from the Company a unit (a "Unit")
consisting of one ten-thousandth of a share of Series A Junior Participating
Preferred Stock, par value $0.01 per share (the "Preferred Stock"), at a
Purchase Price of $150.00 per Unit (the "Purchase Price"), subject to
adjustment. The description and terms of the Rights are set forth in the
Rights Agreement (the "Rights Agreement"), dated as of August 7, 1998, between
the Company and BankBoston, N.A., as Rights Agent (the "Rights Agent").

                  Initially, the Rights will be attached to all Common Stock
certificates representing shares then outstanding and no separate Rights
Certificate will be distributed. The Rights will separate from the Common
Stock and a Distribution Date will occur upon the earlier of (i) ten (10) days
following a public announcement that a person or group of affiliated or
associated persons (an "Acquiring Person") has acquired, or obtained the right
to acquire, beneficial ownership of 20% or more of the outstanding shares of
Common Stock (the "Stock Acquisition Date") or (ii) ten (10) business days (or
such later date as may be determined by the Board of Directors) following the
commencement of a tender offer or exchange offer that would result in a person
or group beneficially owning 20% or more of such outstanding shares of Common
Stock. The definition of Acquiring Person excludes any Exempted Person (as
defined below). 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 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.

                  Any person who, together with all affiliates and associates
of such person, is the beneficial owner of Common Stock, options and/or
warrants exercisable for shares of Common Stock representing 20% or more of
the shares of Common Stock outstanding on the date the Board of Directors
authorizes the rights dividend (the "Rights Dividend Declaration Date"), will
be an "Exempted Person." In addition, any person who, together with all
affiliates and associates of such person, becomes the beneficial owner of
Common Stock, options and/or warrants exercisable for shares of Common Stock
representing 20% or more of the shares of Common Stock then outstanding as a
result of a purchase by the Company or any of its Subsidiaries of shares of
Common Stock will also be an "Exempted Person." However, any such person will
no longer be deemed to be an Exempted Person and will be deemed to be an
Acquiring Person if such person, together with all affiliates and associates
of such person, becomes the beneficial owner, at any time after the date such
person became the beneficial


                                      C-1

<PAGE>



owner of 20% or more of the then outstanding shares of Common Stock, of
additional securities representing 1,000 or more shares of Common Stock,
except if such additional securities are acquired (x) pursuant to the exercise
of options or warrants to purchase Common Stock outstanding and beneficially
owned by such person as of the date such person became the beneficial owner of
20% or more of the then outstanding shares of Common Stock or as a result of
an adjustment to the number of shares of Common Stock for which such options
or warrants are exercisable pursuant to the terms thereof, or (y) as a result
of a stock split, stock dividend or the like. A purchaser, assignee or
transferee of the shares of Common Stock (or options or warrants exercisable
for Common Stock) from an Exempted Person will not thereby become an Exempted
Person, except that a transferee from the estate of an Exempted Person who
receives Common Stock as a bequest or inheritance from an Exempt Person shall
be an Exempt Person so long as such transferee continues to be the beneficial
owner of the requisite percentage of shares.

                  The Rights are not exercisable until the Distribution Date
and will expire at the close of business on August 27, 2008 unless earlier
redeemed by the Company as described below. At no time will the Rights have
any voting power.

                  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 prior to the
Distribution Date will be issued with Rights.

                  In the event that an Acquiring Person, other than an
Exempted Person, becomes the beneficial owner of 20% or more of the then
outstanding shares of Common Stock (unless such acquisition is made pursuant
to a tender or exchange offer for all outstanding shares of the Company, at a
price determined by at least 75% of the directors of the Company then in
office to be fair and otherwise in the best interest of the Company and its
stockholders after receiving advice from one or more investment banking firms
(a "Qualifying 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. The Exercise Price is the Purchase Price
times the number of shares of Common Stock associated with each Right
(initially, one). Notwithstanding any of the foregoing, following the
occurrence of the events set forth in this paragraph (the "Flip-In Events"),
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
Flip-In Events set forth above until such time as the Rights are no longer
redeemable by the Company as set forth below.

                  In the event that following the Stock Acquisition Date, (i)
the Company engages in a merger or business combination transaction in which
the Company is not the surviving corporation (other than a merger consummated
pursuant to a Qualifying Offer); (ii) the Company engages in a merger or
business combination transaction in which the Company is the surviving
corporation and the Common Stock is changed or exchanged; or (iii) 50% or more
of the


                                      C-2

<PAGE>



Company's assets 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 of the Right, common
stock of the acquiring company having a value equal to two times the Exercise
Price of the Right.

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

                  With certain exceptions, no adjustments in the Purchase
Price will be required until cumulative adjustments amount to at least 1% of
the Purchase Price. No fractional Units will be issued and, in lieu thereof,
an adjustment in cash will be made based on the market price of the Preferred
Stock on the last trading date prior to the date of exercise.

                  At any time after the Stock Acquisition Date and prior to
the acquisition by the Acquiring Person of 50% or more of the then outstanding
shares of Common Stock, the Board of Directors of the Company may exchange the
Rights (other than Rights owned by an Acquiring Person), in whole or in part,
at an exchange ratio equal to one share of Common Stock per Right (subject to
adjustment). Any such exchange shall require approval of at least 75% of the
directors of the Company then in office.

                  At any time until ten (10) days following the Stock
Acquisition Date, the Company may redeem the Rights in whole, but not in part,
at a price of $0.001 per Right. Under certain circumstances, the decision to
redeem shall require the approval of at least 75% of the directors of the
Company then in office. Immediately upon the action of the Board of Directors
ordering redemption of the Rights, the Rights will terminate and the only
right of the holders of Rights will be to receive the $0.001 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 as set forth above or in the event the Rights
are redeemed.

                  Other than those provisions relating to the principal
economic terms of the Rights, any of the provisions of the Rights Agreement
may be amended by the Board of Directors of the Company (in certain
circumstances with the approval of 75% of the directors of the Company then in
office) prior to the Distribution Date. After the Distribution Date, the
provisions of the


                                      C-3

<PAGE>


Rights Agreement may be amended by the Board (in certain circumstances, with
the approval of at least 75% of the directors of the Company then in office)
in order to cure any ambiguity, to make changes which do not adversely affect
the interests of holders of Rights (excluding the interest of any Acquiring
Person), or to shorten or lengthen any time period under the Rights Agreement;
provided, however, that no amendment to adjust the time period governing
redemption shall 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 a Registration Statement
on Form 8-A. A copy of the Rights Agreement is available free of charge from
the Company. This Summary of 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.
