Replacement of Shareholder Rights Plan
- --------------------------------------
      On June 20, 1996, the Board of Directors of Nalco Chemical Company 
(the "Company") declared a dividend distribution of one Right for each 
outstanding share of common stock, par value $0.1875 per share (the "Common 
Stock"), of the Company to shareholders of record at the close of business 
on September 1, 1996 (the "Record Date").  Except as described below, each 
Right, when exercisable, entitles the registered holder to purchase from 
the Company one one-thousandth of a share of Series C Junior Participating 
Preferred Stock, par value $1.00 per share, (the "Preferred Stock"), at a 
price of $125.00 per one one-thousandth of a share (the "Purchase Price"), 
subject to adjustment.  The description and terms of the Rights are set 
forth in a Rights Agreement (the "Rights Agreement") between the Company 
and First Chicago Trust Company, as Rights Agent.

      Initially, the Rights will be attached to all Common Stock 
certificates representing shares then outstanding, and no separate Right 
certificates will be distributed.  Until the earlier to occur of (i) 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 15% or more of the outstanding 
shares of Common Stock (the "Shares Acquisition Date") or (ii) 15 business 
days (or such later date as may be determined by action of the Board of 
Directors of the Company (the "Board of Directors") prior to the time that 
any person becomes an Acquiring Person) following the commencement of (or a 
public announcement of an intention to make) a tender or exchange offer if, 
upon consummation thereof, such person or group would be the  beneficial 
owner of 15% or more of such outstanding shares of Common Stock (the 
earlier of such dates being called the "Distribution Date"), the Rights 
will be evidenced by the Common Stock certificates, together with a copy of 
the Summary of Rights Plan and not by separate certificates.

      The Rights Agreement also provides that, until the Distribution Date, 
the Rights will be transferred with and only with the Common Stock.  Until 
the Distribution Date (or earlier redemption, expiration or termination of 
the Rights), the transfer of any certificates for Common Stock, with or 
without a copy of this Summary of Rights Plan, will also constitute the 
transfer of the Rights associated with the Common Stock represented by such 
certificates.  As soon as practicable following the Distribution Date, 
separate certificates evidencing the Rights ("Right Certificates") will be 
mailed to holders of record of the Common Stock as of the close of business 
on the Distribution Date and, thereafter, such separate Right Certificates 
alone will evidence the Rights.

      The Rights are not exercisable until the Distribution Date and will 
expire at the earliest of (i) August 31, 2006 (the "Final Expiration 
Date"), (ii) the redemption of the Rights by the Company as described below 
and (iii) the exchange of all Rights for Common Stock as described below.

      In the event that any person (other than the Company, its affiliates 
or any person receiving newly-issued shares of Common Stock directly from 
the Company) becomes the beneficial owner of 15% or more of the then 
outstanding shares of Common Stock, each holder of a Right will thereafter 
have the right to receive, upon exercise at the then current exercise price 
of the Right, 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 Rights Agreement contains an exemption 
for any issuance of Common Stock by the Company directly to any person (for 
example, in a private placement or an acquisition by the Company in which 
Common Stock is used as consideration), even if that person would become 
the beneficial owner of 15% or more of the Common Stock, provided that such 
person does not acquire any additional shares of Common Stock.

      In the event that, at any time following the Shares Acquisition Date, 
the Company is acquired in a merger or other business combination 
transaction or 50% or more of the Company's assets or earning power are 
sold, proper provision will be made so that each holder of a Right will 
thereafter have the right to receive, upon exercise at the then-current 
exercise price of the Right, common stock of the acquiring or surviving 
company having a value equal to two times the exercise price of the Right.

      Notwithstanding the foregoing, following the occurrence of any of the 
events set forth in the preceding two paragraphs (the "Triggering Events"), 
any Rights that are, or (under certain circumstances specified in the 
Rights Agreement) were, beneficially owned by any Acquiring Person will 
immediately become null and void.

      The Purchase Price payable, and the number of shares 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, 
among other circumstances, in the event of a stock dividend on, or a 
subdivision, split, combination, consolidation or reclassification of, the 
Preferred Stock or the Common Stock, or a reverse split of the outstanding 
shares of Preferred Stock or the Common Stock.

      At any time after the acquisition by a person or group of affiliated 
or associated persons of beneficial ownership of 15% or more of the 
outstanding Common Stock and prior to the acquisition by such person or 
group of 50% or more of the outstanding Common Stock, the Board of 
Directors may exchange the Rights (other than Rights owned by such person 
or group, which have become void), in whole or in part, at an exchange 
ratio of one share of Common Stock per Right (subject to adjustment).  

      With certain exceptions, no adjustment in the Purchase Price will be 
required until cumulative adjustments require an adjustment of at least 1% 
in the Purchase Price.  The Company will not be required to issue 
fractional shares of Preferred Stock or Common Stock (other than fractions 
in multiples of one one-thousandths of a share of Preferred Stock) and, in 
lieu thereof, an adjustment in cash may be made based on the market price 
of the Preferred Stock or Common Stock on the last trading date prior to 
the date of exercise.

      At any time after the date of the Rights Agreement until the time 
that a person becomes an Acquiring Person, the Board of Directors may 
redeem the Rights in whole, but not in part, at a price of $.01 per Right 
(the "Redemption Price"), which may (at the option of the Company) be paid 
in cash, shares of Common Stock or other consideration deemed appropriate 
by the Board of Directors.  Upon the effectiveness of any 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 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.

      The provisions of the Rights Agreement may be amended by the Company, 
except that any amendment adopted after the time that a person becomes an 
Acquiring Person may not adversely affect the interests of holders of 
Rights.

      As of May 31, 1996, there were 67,370,313 shares of Common 
Stock outstanding.  Each outstanding share of Common Stock on 
September 1, 1996 will receive one Right.  Two hundred thousand
(200,000) shares of Preferred Stock will be reserved for issuance 
in the event of exercise of the Rights.

      The Rights have certain anti-takeover effects.  The Rights will cause 
substantial dilution to a person or group that attempts to acquire the 
Company without conditioning the offer on the Rights being redeemed or a 
substantial number of Rights being acquired, and under certain 
circumstances the Rights beneficially owned by such a person or group may 
become void.  The Rights should not interfere with any merger or other 
business combination approved by the Board of Directors because, if the 
Rights would become exercisable as a result of such merger or business 
combination, the Board of Directors may, at its option, at any time prior 
to the time that any Person becomes an Acquiring Person, redeem all (but 
not less than all) of the then outstanding Rights at the Redemption Price.

      A copy of the Rights Agreement is being filed with the Securities and 
Exchange Commission as an exhibit to this Current Report on Form 8-K.  This 
summary description of the Rights does not purport to be complete and is 
qualified in its entirety by reference to the Rights Agreement.

Bylaw Amendments
- ----------------
      On June 20, 1996, the Board of Directors also adopted certain 
amendments to the Bylaws of the Company.  Among other things, the 
amendments (1) provide that the only business that may be conducted at a 
special meeting is the business specified in the notice of the meeting; (2) 
provide that stockholder proposals and nominations must be given to the 
Company at least 90 days prior to the date of the Company's annual meeting; 
(3) provide that approval of any proposal submitted to stockholders which 
has not been approved by the Board of Directors requires a vote of a 
majority of the voting power of the total shares outstanding rather than 
only a majority of those shares actually voting; (4) update the Bylaws for 
the Series B Preferred Stock held by the ESOP (which carry 20 votes per 
share) to clarify that the required vote of stockholders generally is the 
vote of a majority of the voting power of shares of the Company's 
outstanding voting stock which are voted at the meeting rather than the number 
of shares of voting stock; (5) clarify that, under certain circumstances, 
shares held by a broker or nominee which are present at a meeting but not 
voted for or against a specific proposal because the broker is not 
authorized to vote for or against the proposal shall not be included in 
determining whether a majority of the votes cast have been cast in favor of 
the proposal; and (6) include certain other technical amendments to fix 
improper cross-references and typographical errors.

      The amendments to the Bylaws of the Company are attached hereto as 
Exhibit 3 and are incorporated herein by reference.  The foregoing 
description of the Bylaw amendments does not purport to be complete and is 
qualified in its entirety by reference to Exhibit 3.

                        RIGHTS AGREEMENT


     Rights Agreement, dated as of June 20, 1996 (the
"Agreement"), between Nalco Chemical Company, a Delaware
corporation (the "Company"), and First Chicago Trust Company, a
New York corporation (the "Rights Agent").

                       W I T N E S S E T H:

     WHEREAS, the Board of Directors of the Company has
authorized and declared a dividend of one preferred share
purchase right (a "Right") for each Common Share (as hereinafter
defined) of the Company outstanding as of the close of business
on September 1, 1996 (the "Record Date"), each Right representing
the right to purchase one one-thousandth of a Preferred Share (as
hereinafter defined), upon the terms and subject to the
conditions herein set forth, and has further authorized and
directed the issuance of one Right with respect to each Common
Share that shall become outstanding between the Record Date and
the Expiration Date (as such term is hereinafter defined).

     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:

          "Acquiring Person" shall mean any Person (as such term
is hereinafter defined) who or which, together with all
Affiliates and Associates (as such terms are hereinafter defined)
of such Person, shall be the Beneficial Owner (as such term is
hereinafter defined) of 15% or more of the Common Shares of the
Company then outstanding, but shall not include the Company, any
Subsidiary (as such term is hereinafter defined) of the Company,
any employee benefit plan of the Company or any Subsidiary of the
Company, or any Person holding Common Shares for or pursuant to
the terms of any such plan.  Notwithstanding the foregoing, no
Person shall become an "Acquiring Person" as the result of (a) an
acquisition of Common Shares by the Company which, by reducing
the number of shares outstanding, increases the proportionate
number of shares beneficially owned by such Person to 15% or more
of the Common Shares of the Company then outstanding or (b) the
acquisition by such Person of newly issued Common Shares directly
from the Company (it being understood that a purchase from an
underwriter or other intermediary is not directly from the
Company); provided, however, that if a Person shall become the
Beneficial Owner of 15% or more of the Common Shares of the
Company then outstanding by reason of share purchases by the
Company or the receipt of newly issued Common Shares directly
from the Company and shall, after such share purchases or direct
issuance by the Company, become the Beneficial Owner of any
additional Common Shares of the Company, then such Person shall
be deemed to be an "Acquiring Person"; provided further, however,
that any transferee from such Person who becomes the Beneficial
Owner of 15% or more of the Common Shares of the Company then
outstanding shall nevertheless be deemed to be an "Acquiring
Person."  Notwithstanding the foregoing, if the Board of
Directors of the Company determines in good faith that a Person
who would otherwise be an "Acquiring Person," as defined pursuant
to the foregoing provisions of this paragraph, has become such
inadvertently, and such Person divests as promptly as practicable
(and in any event within ten business days after notification by
the Company) a sufficient number of Common Shares so that such
Person would no longer be an Acquiring Person, as defined
pursuant to the foregoing provisions of this paragraph, then such
Person shall not be deemed to be an "Acquiring Person" for any
purposes of this Agreement.

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

          A Person shall be deemed the "Beneficial Owner" of and
shall be deemed to have "beneficial ownership" of or
"beneficially own" any securities:  

          (a)  which such Person or any of such Person's
     Affiliates or Associates beneficially owns, directly or
     indirectly;
          (b)  which such Person or any of such Person's
     Affiliates or Associates, directly or indirectly, has (A)
     the right to acquire (whether such right is exercisable
     immediately or only after the passage of time) pursuant to
     any agreement, arrangement or understanding, whether written
     or oral (other than customary agreements with and between
     underwriters and selling group members with respect to a
     bona fide public offering of securities), or upon the
     exercise of conversion rights, exchange rights, rights
     (other than these Rights), warrants or options, or
     otherwise; provided, however, that a Person shall not be
     deemed the Beneficial Owner of, or to beneficially own,
     securities tendered pursuant to a tender or exchange offer
     made by or on behalf of such Person or any of such Person's
     Affiliates or Associates until such tendered securities are
     accepted for purchase or exchange; (B) the sole or shared
     right to vote or dispose (including any such right pursuant
     to any agreement, arrangement or understanding, whether
     written or oral); provided, however, that a Person shall not
     be deemed the Beneficial Owner of, or to beneficially own,
     any security if the agreement, arrangement or understanding
     to vote such security (1) arises solely from a revocable
     proxy or consent given to such Person in response to a
     public proxy or consent solicitation made pursuant to, and
     in accordance with, the applicable rules and regulations
     promulgated under the Exchange Act and (2) is not also then
     reportable on Schedule 13D under the Exchange Act (or any
     comparable or successor report); or (C) "beneficial
     ownership" (as determined pursuant to Rule 13d-3 (or any
     successor rule) of the General Rules and Regulations under
     the Exchange Act); or
          (c)  which are beneficially owned, directly or
     indirectly, by any other Person (or any Affiliate or
     Associate thereof) with which such Person or any of such
     Person's Affiliates or Associates has any agreement,
     arrangement or understanding, whether written or oral (other
     than customary agreements with and between underwriters and
     selling group members with respect to a bona fide public
     offering of securities) for the purpose of acquiring,
     holding, voting (except to the extent contemplated by the
     proviso to clause (B) of subparagraph (b) of this
     definition) or disposing of any securities of the Company.

          Notwithstanding anything in this definition of
beneficial ownership to the contrary, the phrase "then
outstanding," when used with reference to a Person's beneficial
ownership of securities of the Company, shall mean the number of
such securities then issued and outstanding together with the
number of such securities not then actually issued and
outstanding which such Person would be deemed to own beneficially
hereunder.

          "Business Day" shall mean any day other than a
Saturday, a Sunday, or a day on which banking institutions in
Illinois are authorized or obligated by law or executive order to
close.

          "Close of business" on any given date shall mean
5:00 P.M., Chicago time, on such date; provided, however, that if
such date is not a Business Day it shall mean 5:00 P.M., Chicago
time, on the next succeeding Business Day.

and the Rights Agent hereby accepts such appointment.  The Company
may from time to time appoint such co-Rights Agents as it may deem

     Section 3.  Issue of Right Certificates.

     (a)  Until the earlier of (i) the close of business on the
tenth day after the Shares Acquisition Date or (ii) the close of
business on the fifteenth business day (or such later date as may be
determined by action of the Board of Directors prior to such time as
any Person becomes an Acquiring Person) after the date of the
commencement by any Person (other than the Company, any Subsidiary
of the Company, any employee benefit plan of the Company or of any
Subsidiary of the Company or any entity holding Common Shares for or
pursuant to the terms of any such plan) of, or of the first public
announcement of the intention of any Person (other than the Company,
any Subsidiary of the Company, any employee benefit plan of the
Company or of any Subsidiary of the Company or any entity holding
Common Shares for or pursuant to the terms of any such plan) to
commence, a tender or exchange offer the consummation of which would
result in any Person becoming the Beneficial Owner of Common Shares
aggregating 15% or more of the then outstanding Common Shares
(including any such date which is after the date of this Agreement
and prior to the issuance of the Rights; the earlier of such dates
being herein referred to as the "Distribution Date"), (x) the Rights
will be evidenced (subject to the provisions of Section 3(b) hereof)
by the certificates for Common Shares registered in the names of the
holders thereof (which certificates shall also be deemed 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 Common Shares (including a transfer to the
Company).  As soon as practicable after the Distribution Date, the
Company will prepare and execute, the Rights Agent will countersign,
and the Company will send or cause to be sent (and the Rights Agent
will, if requested, send) by first-class, insured, postage-prepaid
mail, to each record holder of Common Shares as of the close of
business on the Distribution Date, at the address of such holder
shown on the records of the Company, a Right Certificate, in
substantially the form of Exhibit B hereto (a "Right Certificate"),
evidencing one Right for each Common Share so held.  As of the
Distribution Date, the Rights will be evidenced solely by such Right
Certificates.
     (b)  On the Record Date, or as soon as practicable
thereafter, the Company will send a copy of a Summary of Rights
Plan, in substantially the form of Exhibit C hereto (the "Summary
of Rights Plan"), by first class, postage-prepaid mail, to each
record holder of Common Shares as of the close of business on the
Record Date (other than any Acquiring Person or any Associate or
Affiliate of any Acquiring Person), at the address of such holder
shown on the records of the Company.  With respect to
certificates for Common Shares outstanding as of the Record Date,
until the Distribution Date, the Rights will be evidenced by such
certificates registered in the names of the holders thereof
together with the Summary of Rights Plan, and registered holders
of Common Shares shall also be the registered holders of the
associated Rights.  Until the Distribution Date (or the earlier
of the Redemption Date or the Final Expiration Date), the
transfer of any certificate for Common Shares outstanding on the
Record Date, with or without a copy of the Summary of Rights
Plan, shall also constitute the transfer of the Rights associated
with the Common Shares represented thereby.
     (c)  Rights shall be issued in respect of all Common Shares
which are issued (whether originally issued or delivered from the
Company's treasury) after the Record Date but prior to the
earliest of the Distribution Date, the Redemption Date or the
Final Expiration Date.  Certificates representing such Common
Shares shall also be deemed to be certificates for Rights. 
Certificates representing both Common Shares and Rights in
accordance with this Section 3 which are executed and delivered
(whether the Common Shares represented thereby are originally
issued, delivered from the Company's treasury or are presented
for transfer) by the Company (including, without limitation,
certificates representing reacquired Common Shares referred to in
the last sentence of this paragraph (c)) after the Record Date
but prior to the earliest of the Distribution Date, the
Redemption Date or the Final Expiration Date shall have impressed
on, printed on, written on or otherwise affixed to them a legend
substantially equivalent to the following:

     This certificate also evidences and entitles the holder
     hereof to certain rights as set forth in the Rights
     Agreement between Nalco Chemical Company (the
     "Company") and First Chicago Trust Company dated as of
     June 20, 1996 (the "Rights Agreement"), the terms of
     which are hereby incorporated herein by reference and a
     copy of which is on file at the principal offices of
     the Company.  Under certain circumstances, as set forth
     in the Rights Agreement, such Rights will be evidenced
     by separate certificates and will no longer be
     evidenced by this certificate.  The Company will mail
     to the holder of this certificate a copy of the Rights
     Agreement, as in effect on the date of mailing, without
     charge promptly after receipt of a written request
     therefor.  Under certain circumstances set forth in the
     Rights Agreement, Rights issued to, or held by, any
     Person who is, was or becomes an Acquiring Person or an
     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 sub-
     sequent holder, shall become null and void.

Until the Distribution Date, the Rights associated with the
Common Shares shall be evidenced by the certificates representing
the associated Common Shares alone, and the transfer of any such
certificate shall also constitute the transfer of the Rights
associated with the Common Shares represented thereby.  In the
event that the Company purchases or acquires any Common Shares
after the Record Date but prior to the Distribution Date, any
Rights associated with such Common Shares shall be deemed
cancelled and retired so that the Company shall not be entitled
to exercise any Rights associated with the Common Shares which
are no longer outstanding.

     Section 4.  Form of Right Certificates.

     (a)  The Right Certificates (and the forms of election to
purchase Preferred Shares and of assignment to be printed on the
reverse thereof) shall each be substantially in the form set
forth in Exhibit B hereto and may have such marks of
identification or designation and such legends, summaries or
endorsements printed thereon as the Company may deem appropriate
and as are not inconsistent with the provisions of this
Agreement, or as may be required to comply with any applicable
law or with any rule or regulation made pursuant thereto or with
any rule or regulation of any stock exchange on which the Rights
may from time to time be listed, or to conform to usage.  Subject
to the provisions of Section 11 and Section 22 hereof, the Right
Certificates shall entitle the holders thereof to purchase such
number of one one-thousandths of a Preferred Share as shall be
set forth therein at the price per one one-thousandth of a
Preferred Share set forth therein (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 Right 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
such Associate or Affiliate) who becomes a transferee after the
Acquiring Person becomes an Acquiring Person, or (iii) a
transferee of an Acquiring Person (or 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, whether written or oral, regarding the transferred
Rights or (B) a transfer which is part of a plan, arrangement or
understanding, whether written or oral, which has as a primary
purpose or effect avoidance of Section 7(e) hereof, and any Right
Certificate issued pursuant to Section 6 or Section 11 hereof
upon transfer, exchange, replacement or adjustment of any other
Right Certificate referred to in this sentence, shall contain (to
the extent feasible and otherwise reasonably identifiable as
such) the following legend: 

     The Rights represented by this Right 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 Right Certificate
     and the Rights represented hereby may become void in
     the circumstances specified in Section 7(e) of such
     Agreement.

The provisions of Section 7(e) shall apply whether or not any
Right Certificate actually contains the foregoing legend.

     Section 5.  Countersignature and Registration.  The Right
Certificates shall be executed on behalf of the Company by its
Chairman of the Board, its Chief Executive Officer, any Vice
Chairman, its President, any of its Vice Presidents, or its
Treasurer, either manually or by facsimile signature, shall have
affixed thereto the Company's seal or a facsimile thereof, and
shall be attested by the Secretary or an Assistant Secretary of
the Company, either manually or by facsimile signature.  The
Right Certificates shall be manually countersigned by the Rights
Agent and shall not be valid for any purpose unless
countersigned.  In case any officer of the Company who shall have
signed any of the Right Certificates shall cease to be such
officer of the Company before countersignature by the Rights
Agent and issuance and delivery by the Company, such Right
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 Right
Certificates had not ceased to be such officer of the Company;
and any Right Certificate may be signed on behalf of the Company
by any person who, at the actual date of the execution of such
Right Certificate, shall be a proper officer of the Company to
sign such Right Certificate, although at the date of the
execution of this Agreement any such person was not such an
officer.

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

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

     (a)  Subject to the provisions of Sections 4(b), 7(e), 14
and 24 hereof, at any time after the close of business on the
Distribution Date, and at or prior to the close of business on
the earlier of the Redemption Date or the Final Expiration Date,
any Right Certificate or Right Certificates may be transferred,
split up, combined or exchanged for another Right Certificate or
Right Certificates, entitling the registered holder to purchase a
like number of Preferred Shares (or, following a Triggering
Event, Common Shares, other securities or property, as the case
may be) as the Right Certificate or Right Certificates
surrendered then entitled such holder to purchase. Any registered
holder desiring to transfer, split up, combine or exchange any
Right Certificate or Right Certificates shall make such request
in writing delivered to the Rights Agent, and shall surrender the
Right Certificate or Right Certificates to be transferred, split
up, combined or exchanged at the office of the Rights Agent
designated for such purpose.  Neither the Rights Agent nor the
Company shall be obligated to take any action whatsoever with
respect to the transfer of any such surrendered Right Certificate
until the registered holder shall have completed and signed the
certificate contained in the form of assignment on the reverse
side of such Right Certificate accompanied by such documents as
the Rights Agent may deem appropriate and the Company shall have
been provided with 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 Sections 4 and 7
hereof, countersign and deliver to the person entitled thereto a
Right Certificate or Right 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 Right 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 Right Certificate, and, in case of
loss, theft or destruction, of indemnity or security reasonably
satisfactory to them, and, at the Company's request,
reimbursement to the Company and the Rights Agent of all
reasonable expenses incidental thereto, and upon surrender to the
Rights Agent and cancellation of the Right Certificate if
mutilated, the Company will make and deliver a new Right
Certificate of like tenor to the Rights Agent for
countersignature and delivery to the registered holder in lieu of
the Right 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 Right Certificate may exercise the Rights evidenced
thereby (except as otherwise provided herein) in whole or in part
at any time after the Distribution Date upon surrender of the
Right Certificate, with the form of election to purchase on the
reverse side thereof duly executed, to the Rights Agent at the
office of the Rights Agent designated for such purpose, together
with payment of the Purchase Price with respect to each
surrendered Right for the total number of Preferred Shares (or
other securities or property, as the case may be) as to which the
Rights are exercised, at or prior to the earliest of (i) the
close of business on August 31, 2006 (the "Final Expiration
Date"), (ii) the time at which the Rights are redeemed as
provided in Section 23 hereof (the "Redemption Date") (the
earlier of (i) and (ii) being herein referred to as the
"Expiration Date") and (iii) the time at which such Rights are
exchanged as provided in Section 24 hereof.  
     (b)  The Purchase Price for each one one-thousandth of a
Preferred Share pursuant to the exercise of a Right shall
initially be $125.00, shall be subject to adjustment from time to
time as provided in Sections 11 and 13 hereof and shall be
payable in lawful money of the United States of America in
accordance with paragraph (c) below.
     (c)  Upon receipt of a Right Certificate representing
exercisable Rights, with the form of election to purchase and the
certificate on the reverse side of the Right Certificate duly
executed, accompanied by such documents as the Rights Agent may
deem appropriate, payment of the Purchase Price for the shares
(or other securities or property, as the case may be) to be
purchased and an amount equal to any applicable transfer tax
required to be paid by the holder of such Right Certificate in
accordance with Section 9 hereof by certified check, cashier's
check or money order payable to the order of the Company, the
Rights Agent shall thereupon promptly (i) (A) requisition from
any transfer agent of the Preferred Shares (or make available, if
the Rights Agent is the transfer agent of the Preferred Shares)
certificates for the number of Preferred Shares 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 Preferred Shares issuable upon
exercise of the Rights with a depositary agent, requisition from
the depositary agent depositary receipts representing such number
of one one-thousandths of a Preferred Share as are to be
purchased (in which case certificates for the Preferred Shares
represented by such receipts shall be deposited by the transfer
agent with the depositary agent) and the Company will direct the
depositary agent to comply with such request; (ii) when
appropriate, requisition from the Company the amount of cash to
be paid in lieu of issuance of fractional shares in accordance
with Section 14 hereof; (iii) after receipt of such certificates
or depositary receipts, cause the same to be delivered to or upon
the order of the registered holder of such Right Certificate,
registered in such name or names as may be designated by such
holder and (iv) when appropriate, after receipt, deliver such
cash to or upon the order of the registered holder of such Right
Certificate.  In the event that the Company is obligated to issue
other securities (including Common Shares) 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 property are available for
distribution by the Rights Agent, if and when appropriate.
     (d)  In case the registered holder of any Right Certificate
shall exercise less than all the Rights evidenced thereby, a new
Right Certificate evidencing Rights equivalent to the Rights
remaining unexercised shall be issued by the Rights Agent and
delivered to the registered holder of such Right Certificate or
to his duly authorized assigns, subject to the provisions of
Section 14 hereof.

     (e)  Notwithstanding anything in this Agreement to the
contrary, from and after the occurrence of a Triggering Event,
any Rights beneficially owned by (i) an Acquiring Person or an
Associate or Affiliate of an Acquiring Person, (ii) a transferee
of an Acquiring Person (or of any such Associate or Affiliate)
who becomes a transferee after the Acquiring Person becomes an
Acquiring Person, or (iii) a transferee of an Acquiring Person
(or such Associate or Affiliate) who becomes a transferee prior
to or concurrently with the Acquiring Person becoming an
Acquiring Person 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, whether written or oral,
regarding the transferred Rights or (B) a transfer which the
Board of Directors otherwise concludes in good faith is part of a
plan, arrangement or understanding (whether written or oral)
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 any holder of such Rights shall thereupon have no
rights whatsoever with respect to such Rights, whether under any
provision of this Agreement or otherwise, from and after the
occurrence of a Triggering Event.  The Company shall use all
reasonable efforts to ensure that the provisions of this Section
7(e) hereof are complied with, but shall have no liability to any
holder of Rights for the inability 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 the certificate contained in the form of
election to purchase set forth on the reverse side of the Right
Certificate surrendered for such exercise shall have been
completed and signed by the registered holder thereof and the
Company shall have been provided with 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.
     (g)  The Company covenants and agrees that it will cause to
be reserved and kept available out of its authorized and unissued
Preferred Shares (and, following the occurrence of a Triggering
Event, Common Shares and/or other securities) or any Preferred
Shares (and, following the occurrence of a Triggering Event,
Common Shares and/or other securities) held in its treasury, the
number of Preferred Shares (and, following the occurrence of a
Triggering Event, Common Shares and/or other securities) that
will be sufficient to permit the exercise in full of all
outstanding Rights.
     (h)  Notwithstanding any statement to the contrary contained
in this Agreement or in any Right Certificate, if the
Distribution Date or the Shares Acquisition Date shall occur
prior to the Record Date, the provisions of this Agreement,
including (without limitation) Sections 3 and 11(a)(ii), shall be
applicable to the Rights upon their issuance to the same extent
such provisions would have been applicable if the Record Date
were the date of this Agreement.

     Section 8.  Cancellation and Destruction of Right
Certificates.  All Right Certificates surrendered for the purpose
of exercise, transfer, split up, combination or exchange shall,
if surrendered to the Company or to any of its agents, be
delivered to the Rights Agent for cancellation or in cancelled
form, or, if surrendered to the Rights Agent, shall be cancelled
by it, and no Right 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 Right Certificate purchased or acquired by
the Company otherwise than upon the exercise thereof.  The Rights
Agent shall deliver all cancelled Right Certificates to the
Company, or shall, at the written request of the Company, cause
such cancelled Right Certificates to be destroyed, and in such
case cause a certificate of destruction to be delivered to the
Company.

     Section 9.  Availability of Preferred Shares.  The Company
covenants and agrees that it will take all such action as may be
necessary to ensure that all Preferred Shares (and, following the
occurrence of a Triggering Event, Common Shares and/or other
securities) delivered upon exercise of Rights shall, at the time
of delivery of the certificates for such Preferred Shares (and,
following the occurrence of a Triggering Event, Common Shares
and/or other securities), subject to payment of the Purchase
Price, be duly and validly authorized and issued and fully paid
and nonassessable shares.

     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 Right Certificates or of any Preferred Shares (or
Common Shares 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 Right Certificates to a person
other than, or the issuance or delivery of certificates or
depositary receipts for the Preferred Shares (or Common Shares
and/or other securities, as the case may be) in a name other than
that of, the registered holder of the Right Certificate
evidencing Rights surrendered for exercise or to issue or to
deliver any certificates or depositary receipts for Preferred
Shares (or Common Shares and/or other securities, as the case may
be) upon the exercise of any Rights until any such tax shall have
been paid (any such tax being payable by the holder of such Right
Certificate at the time of surrender) or until it has been
established to the Company's reasonable satisfaction that no such
tax is due.

     Section 10.  Preferred Shares Record Date.  Each person in
whose name any certificate for Preferred Shares (or Common Shares
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 the shares or securities
represented thereby on, and such certificate shall be dated, the
date upon which the Right Certificate evidencing such Rights was
duly surrendered and payment of the Purchase Price (and any
applicable transfer taxes) was made; provided, however, that if
the date of such surrender and payment is a date upon which the
Preferred Shares (or Common Shares 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 or securities on, and such certificate shall be dated, the
next succeeding Business Day on which the Preferred Shares (or
Common Shares 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 Right Certificate
shall not be entitled to any rights of a holder of Preferred
Shares (or Common Shares and/or other securities, as the case may
be) 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 of Shares
or Number of Rights.  The Purchase Price, the number of Preferred
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 Shares payable in Preferred Shares, (B)
     subdivide the outstanding Preferred Shares, (C) combine the
     outstanding Preferred Shares into a smaller number of
     Preferred Shares or (D) issue any shares of its capital
     stock in a reclassification of the Preferred Shares
     (including any such reclassification in connection with a
     consolidation or merger in which the Company is the
     continuing or surviving corporation), 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 capital stock issuable on such date, shall be
     proportionately adjusted so that the holder of any Right
     exercised after such time shall be entitled to receive the
     aggregate number and kind of shares of capital stock which,
     if such Right had been exercised immediately prior to such
     date and at a time when the Preferred Shares transfer books
     of the Company were open, he would have owned upon such
     exercise and been entitled to receive by virtue of such
     dividend, subdivision, combination or reclassification;
     provided, however, that in no event shall the consideration
     to be paid upon the exercise of one Right be less than the
     aggregate par value of the shares of capital stock of the
     Company issuable upon exercise of one Right.  If an event
     occurs which would require an adjustment under both Section
     11(a)(i) and Section 11(a)(ii), 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).
          (ii)  Subject to Section 24 of this Agreement, in the
     event any Person becomes an Acquiring Person, each holder of
     a Right, except as provided below and in Section 7(e)
     hereof, shall thereafter have a right to receive, upon
     exercise thereof at a price equal to the then current
     Purchase Price multiplied by the number of one one-
     thousandths of a Preferred Share for which a Right is then
     exercisable, in accordance with the terms of this Agreement
     and in lieu of Preferred Shares, such number of Common
     Shares of the Company as shall equal the result obtained by
     (x) multiplying the then current Purchase Price by the
     number of one one-thousandths of a Preferred Share for which
     a Right is then exercisable and dividing that product by (y)
     50% of the then current per share market price of the
     Company's Common Shares (determined pursuant to Section
     11(d) hereof) on the date of the occurrence of such event. 
     In the event that any Person shall become an Acquiring
     Person and the Rights shall then be outstanding, the Company
     shall not take any action which would eliminate or diminish
     the benefits intended to be afforded by the Rights.
          (iii)  In lieu of issuing Common Shares of the Company
     in accordance with Section 11(a)(ii) hereof, the Company
     may, in the sole discretion of the Board of Directors, elect
     to (and, in the event that the Board of Directors has not
     exercised the exchange right contained in Section 24 hereof
     and there are not sufficient issued but not outstanding and
     authorized but unissued Common Shares to permit the exercise
     in full of the Rights in accordance with the foregoing
     subparagraph (ii), the Company shall) take all such action
     as may be necessary to authorize, issue or pay, upon the
     exercise of the Rights, cash (including by way of a
     reduction of the Purchase Price), property, other securities
     or any combination thereof having an aggregate value equal
     to the value of the Common Shares of the Company which
     otherwise would have been issuable pursuant to Section
     11(a)(ii), which aggregate value shall be determined by a
     majority of the Board of Directors.  For purposes of the
     preceding sentence, the value of the Common Shares shall be
     determined pursuant to Section 11(d) hereof and the value of
     any equity securities which a majority of the Board of
     Directors determines to be a "common stock equivalent"
     (including the Preferred Shares, in such ratio as the Board
     of Directors shall determine) shall be deemed to have the
     same value as the Common Shares.  Any such election by the
     Board of Directors must be made and publicly announced
     within 60 days following the date on which the event
     described in Section 11(a)(ii) shall have occurred. 
     Following the occurrence of the event described in Section
     11(a)(ii), a majority of the Board of Directors then in
     office may suspend the exercisability of the Rights for a
     period of up to 60 days following the date on which the
     event described in Section 11(a)(ii) shall have occurred to
     the extent that such directors have not determined whether
     to exercise the company's right of election under this
     Section 11(a)(iii).  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.
     (b)  In case the Company shall fix a record date for the
issuance of rights, options or warrants to all holders of
Preferred Shares entitling them (for a period expiring within 45
calendar days after such record date) to subscribe for or
purchase Preferred Shares (or shares having the same rights,
privileges and preferences as the Preferred Shares ("equivalent
preferred shares")) or securities convertible into Preferred
Shares or equivalent preferred shares at a price per Preferred
Share or equivalent preferred share (or having a conversion price
per share, if a security convertible into Preferred Shares or
equivalent preferred shares) less than the then current per share
market price of the Preferred Shares (as defined in Section
11(d)) 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
Preferred Shares outstanding on such record date plus the number
of Preferred Shares which the aggregate offering price of the
total number of Preferred Shares and/or equivalent preferred
shares so to be offered (and/or the aggregate initial conversion
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 Preferred Shares outstanding on such
record date plus the number of additional Preferred Shares and/or
equivalent preferred shares to be offered for subscription or
purchase (or into which the convertible securities so to be
offered are initially convertible); provided, however, that in no
event shall the consideration to be paid upon the exercise of one
Right be less than the aggregate par value of the shares of
capital stock of the Company issuable upon exercise of one Right. 
In case such subscription price may be paid in a consideration
part or all of which shall be in a form other than cash, the
value of such consideration shall be as determined in good faith
by 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.  Preferred Shares 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, options 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 the
making of a distribution to all holders of the Preferred Shares
(including any such distribution made in connection with a
consolidation or merger in which the Company is the continuing or
surviving corporation) of evidences of indebtedness or assets
(other than a regular quarterly cash dividend or a dividend
payable in Preferred Shares) 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 then current per share market
price of the Preferred Shares on such record date, less the fair
market value (as determined in good faith by the Board of
Directors of the Company, whose determination shall be described
in a statement filed with the Rights Agent) of the portion of the
assets or evidences of indebtedness so to be distributed or of
such subscription rights or warrants applicable to one Preferred
Share, and the denominator of which shall be such current per
share market price of the Preferred Shares; provided, however,
that in no event shall the consideration to be paid upon the
exercise of one Right be less than the aggregate par value of the
shares of capital stock of the Company to be issued upon exercise
of one Right.  Such adjustments shall be made successively
whenever such a record date is fixed; and in the event that such
distribution is not so made, the Purchase Price shall again be
adjusted to be the Purchase Price which would then be in effect
if such record date had not been fixed.
          (d)  (i)  For the purpose of any computation hereunder,
     other than under Section 11(a)(iii) hereof, the "current per
     share market price" of any security (a "Security" for the
     purpose of this Section 11(d)(i)) on any date shall be
     deemed to be the average of the daily closing prices per
     share of such Security for the 30 consecutive Trading Days
     (as such term is hereinafter defined) immediately prior to
     such date, and for the purpose of any computation under
     Section 11(a)(iii) hereof, the "current per share market
     price" of a Security on any date shall be deemed to be the
     average of the daily closing prices per share of such
     Security for thirty (30) consecutive Trading Days
     immediately following such date; provided, however, that in
     the event that the current per share market price of the
     Security is determined during a period following the
     announcement by the issuer of such Security of (A) a
     dividend or distribution on such Security payable in shares
     of such Security or securities convertible into such shares
     (other than the Rights), or (B) any subdivision, combination
     or reclassification of such Security and prior to the
     expiration of 30 Trading Days after the ex-dividend date for
     such dividend or distribution, or the record date for such
     subdivision, combination or reclassification, then, and in
     each such case, the "current per share market price" shall
     be appropriately adjusted to reflect the current market
     price per share equivalent (ex-dividend) of such Security. 
     The closing price for each day shall be the last sale price,
     regular way, or, in case no such sale takes place on such
     day, the average of the closing bid and asked prices,
     regular way, in either case as reported in the principal
     consolidated transaction reporting system with respect to
     securities listed or admitted to trading on the New York
     Stock Exchange or, if the Security is not listed or admitted
     to trading on the New York Stock Exchange, as reported in
     the principal consolidated transaction reporting system with
     respect to securities listed on the principal national
     securities exchange on which the Security is listed or
     admitted to trading or, if the Security is not listed or
     admitted to trading on any national securities exchange, the
     last quoted price or, if not so quoted, the average of the
     high bid and low asked prices in the over-the-counter
     market, as reported by the National Association of
     Securities Dealers, Inc. Automated Quotation System
     ("NASDAQ") or such other system then in use, or, if on any
     such date the Security is 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 Security selected by the Board of Directors of
     the Company.  If on any such date no market maker is making
     a market in the Security, the fair value of such Security on
     such date (as determined in good faith by the Board of
     Directors of the Company) shall be used.  The term "Trading
     Day" shall mean a day on which the principal national
     securities exchange on which the Security is listed or
     admitted to trading is open for the transaction of business
     or, if the Security is not listed or admitted to trading on
     any national securities exchange, a Business Day.
          (ii)  For the purpose of any computation hereunder, the
     "current per share market price" of the Preferred Shares
     shall be determined in accordance with the method set forth
     in Section 11(d)(i).  If the Preferred Shares are not
     publicly traded, the "current per share market price" of the
     Preferred Shares shall be conclusively deemed to be the
     current per share market price of the Common Shares of the
     Company as determined pursuant to Section 11(d)(i)
     (appropriately adjusted to reflect any stock split, stock
     dividend or similar transaction occurring after the date
     hereof), multiplied by one thousand.  If neither the Common
     Shares of the Company nor the Preferred Shares are publicly
     held or so listed or traded, "current per share market
     price" 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.
     (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 one one-millionth of a
Preferred Share or one ten-thousandth of any other share or
security, 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 years from
the date of the transaction which requires such adjustment or
(ii) the date of the expiration of the right to exercise any
Rights.
     (f)  If as a result of an adjustment made pursuant to
Section 11(a) or Section 13(a) hereof, the holder of any Right
thereafter exercised shall become entitled to receive any shares
of capital stock of the Company other than Preferred Shares,
thereafter the number of such other shares so receivable upon
exercise of any Right 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 Shares contained
in this Section 11, and the provisions of Sections 7, 9, 10, 13
and 14 with respect to the Preferred Shares shall apply on like
terms to any such other shares.
     (g)  All Rights originally issued by the Company subsequent
to any adjustment made to the Purchase Price hereunder shall
evidence the right to purchase, at the adjusted Purchase Price,
the number of one one-thousandths of a Preferred Share
purchasable from time to time hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.
     (h)  Unless the Company shall have exercised its election as
provided in Section 11(i), upon each adjustment of the Purchase
Price as a result of the calculations made in Sections 11(b) and
(c), each Right outstanding immediately prior to the making of
such adjustment shall thereafter evidence the right to purchase,
at the adjusted Purchase Price, that number of one one-
thousandths of a Preferred Share (calculated to the nearest one
one-millionth of a Preferred Share) obtained by (i) multiplying
(x) the number of one one-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 substitution for any adjustment in the number of one one-
thousandths of a Preferred Share purchasable upon the exercise of
a Right.  Each of the Rights outstanding after such adjustment of
the number of Rights shall be exercisable for the number of one
one-thousandths of a Preferred Share for which a Right was
exercisable immediately prior to such adjustment.  Each Right
held of record prior to such adjustment of the number of Rights
shall become that number of Rights (calculated to the nearest one
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 Right Certificates have been issued,
shall be at least 10 days later than the date of the public
announcement.  If Right 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 Right Certificates on such
record date Right 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 Right Certificates held
by such holders prior to the date of adjustment, and upon
surrender thereof, if required by the Company, new Right
Certificates evidencing all the Rights to which such holders
shall be entitled after such adjustment.  Right Certificates so
to be distributed shall be issued, executed and countersigned in
the manner provided for herein and shall be registered in the
names of the holders of record of Right Certificates on the
record date specified in the public announcement.
     (j)  Irrespective of any adjustment or change in the
Purchase Price or the number of one one-thousandths of a
Preferred Share issuable upon the exercise of the Rights, the
Right Certificates theretofore and thereafter issued may continue
to express the Purchase Price and the number of one one-
thousandths of a Preferred Share which were expressed in the
initial Right Certificates issued hereunder.
     (k)  Before taking any action that would cause an adjustment
reducing the Purchase Price below one one-thousandth of the then
par value, if any, of the Preferred Shares issuable upon exercise
of the Rights, the Company shall take any corporate action which
may, in the opinion of its counsel, be necessary in order that
the Company may validly and legally issue fully paid and
nonassessable Preferred Shares at such adjusted 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 issuing to the holder of
any Right exercised after such record date of the Preferred
Shares and other capital stock or securities of the Company, if
any, issuable upon such exercise over and above the Preferred
Shares 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 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 it in its sole discretion shall determine to be
advisable in order that any consolidation or subdivision of the
Preferred Shares, issuance wholly for cash of any Preferred
Shares at less than the current market price, issuance wholly for
cash of Preferred Shares or securities which by their terms are
convertible into or exchangeable for Preferred Shares, dividends
on Preferred Shares payable in Preferred Shares or issuance of
rights, options or warrants referred to hereinabove in Section
11(b), hereafter made by the Company to holders of its Preferred
Shares shall not be taxable to such stockholders.
     (n)  In the event that at any time after the date of this
Agreement and prior to the Distribution Date, the Company shall
(i) declare or pay any dividend on the Common Shares payable in
Common Shares or (ii) effect a subdivision, combination or
consolidation of the Common Shares (by reclassification or
otherwise than by payment of dividends in Common Shares) into a
greater or lesser number of Common Shares, then in any such case
(i) the number of one one-thousandths of a Preferred Share
purchasable after such event upon proper exercise of each Right
shall be determined by multiplying the number of one one-
thousandths of a Preferred Share so purchasable immediately prior
to such event by a fraction, the numerator of which is the number
of Common Shares outstanding immediately before such event, and
the denominator of which is the number of Common Shares
outstanding immediately after such event, and (ii) each Common
Share outstanding immediately after such event shall have issued
with respect to it that number of Rights which each Common Share
outstanding immediately prior to such event had issued with
respect to it.  The adjustments provided for in this
Section 11(n) shall be made successively whenever such a dividend
is declared or paid or such a subdivision, combination or
consolidation is effected.
     (o)  So long as the shares issuable 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.
     (p)  The Company shall use its best efforts to (i) file, as
soon as practicable following the first occurrence of a
Triggering Event, a registration statement under the Securities
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 Securities Act) until the date of the
expiration of the Rights.  The Company will also take such action
as may be appropriate under the blue sky laws of the various
states.  The Company may temporarily suspend, for a period of
time not to exceed 90 days, the exercisability of the Rights in
order to prepare and file such registration statement or in order
to comply with such blue sky laws.  Upon any such suspension, the
Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended.
     Section 12.  Certificate of Adjusted Purchase Price or 
Number of Shares.  Whenever an adjustment is made as provided in
Section 11 or 13 hereof, the Company shall promptly (a) prepare a
certificate setting forth such adjustment, and a brief statement
of the facts accounting for such adjustment, (b) file with the
Rights Agent and with each transfer agent for the Common Shares
or the Preferred Shares a copy of such certificate and (c) mail a
brief summary thereof to each holder of a Right Certificate in
accordance with Section 25 hereof.  The Rights Agent shall be
fully protected in relying on any such certificate and on any
adjustment therein contained and may assume that no adjustment
has been made unless and until it shall have received such
certificate.

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

     (a)  If after the Shares Acquisition Date, directly or
indirectly, (x) the Company shall consolidate with, or merge with
and into, any other Person, (y) any Person shall consolidate with
the Company, or merge with and into the Company and the Company
shall be the continuing or surviving corporation of such merger
and, in connection with such merger, all or part of the Common
Shares shall be changed into or exchanged for stock or other
securities of any other Person (or the Company) 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 or more transactions, assets or
earning power aggregating 50% or more of the assets or earning
power of the Company and its Subsidiaries (taken as a whole) to
any Person or Persons other than the Company or one or more of
its wholly-owned Subsidiaries, then, and in each such case,
proper provision shall be made so that (i) each holder of a Right
(except as otherwise provided herein) shall thereafter have the
right to receive, upon the exercise thereof at a price equal to
the then current Purchase Price multiplied by the number of one
one-thousandths of a Preferred Share for which a Right is then
exercisable, in accordance with the terms of this Agreement and
in lieu of Preferred Shares, such number of validly authorized
and issued, fully paid, nonassessable and freely tradeable Common
Shares of the Principal Party (as hereinafter defined), free and
clear of all liens, rights of call or first refusal, encumbrances
or other adverse claims, as shall equal the result obtained by
(A) multiplying the then current Purchase Price by the number of
one one-thousandths of a Preferred Share for which a Right is
then exercisable (or, if such Right is not then exercisable for a
number of one one-thousandths of a Preferred Share, the number of
such fractional shares for which it was exercisable immediately
prior to an event described under Section 11(a)(ii) hereof) and
dividing that product by (B) 50% of the then current per share
market price of the Common Shares of such Principal Party
(determined pursuant to Section 11(d) hereof) on the date of
consummation of such consolidation, merger, sale or transfer;
(ii) such Principal Party shall thereafter be liable for, and
shall assume, by virtue of such consolidation, merger, sale or
transfer, or otherwise, 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; and
(iv) such Principal Party shall take such steps (including, but
not limited to, the reservation of a sufficient number of its
Common Shares in accordance with Section 9 hereof) in connection
with such consummation as may be necessary to assure that the
provisions hereof shall thereafter be applicable, as nearly as
reasonably may be, in relation to its Common Shares thereafter
deliverable upon the exercise of the Rights.  
     (b)  "Principal Party" shall mean:

          (i)  In the case of any transaction described in (x) or
     (y) of the first sentence of Section 13(a), the Person that
     is the issuer of any securities into which Common Shares of
     the Company are converted in such merger or consolidation,
     and if no securities are so issued, the Person that is the
     surviving entity of such merger or consolidation (including
     the Company if applicable); and 
          (ii)  in the case of any transaction described in (z)
     of the first sentence in 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 described in clauses
(b)(i) and (b)(ii):  (1) if the Common Shares of such Person are
not at such time and have not been continuously over the
preceding 12-month period registered under Section 12 of the
Exchange Act, and such Person is a direct or indirect Subsidiary
of another Person the Common Shares of which are and have been so
registered, "Principal Party" shall refer to such other Person;
(2) in case such Person is a Subsidiary, directly or indirectly,
or more than one Person, the Common Shares 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
Shares having the greatest aggregate market value; and (3) in
case such Person is owned, directly or indirectly, by a joint
venture formed by two or more Persons that are not owned,
directly or indirectly, by the same Person, the rules set forth
in (1) and (2) above shall apply to each of the chains of
ownership having an interest in such joint venture as if such
party were a "Subsidiary" of both or all of such joint venturers
and the Principal Parties in each such chain shall bear the
obligations set forth in this Section 13 in the same ratio as
their direct or indirect interests in such Person bear to the
total of such interests.
     (c)  The Company shall not consummate any such
consolidation, merger, sale or transfer unless the Principal
Party shall have sufficient Common Shares authorized to permit
the full exercise of the Rights and 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 Securities 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 Securities Act) until the Expiration Date;
          (ii)  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; and 
          (iii)  take such actions as may be necessary or
     appropriate under the blue sky laws of the various states.  

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

     Section 14.  Fractional Rights and Fractional Shares.  
     (a)  The Company shall not be required to issue fractions of
Rights or to distribute Right Certificates which evidence
fractional Rights.  In lieu of such fractional Rights, there may
be paid to the registered holders of the Right Certificates with
regard to which such fractional Rights would otherwise be
issuable, an amount in cash equal to the same fraction of the
current market value of a whole Right.  For the purposes of this
Section 14(a), the current market value of a whole Right shall be
the closing price of the Rights for the Trading Day immediately
prior to the date on which such fractional Rights would have been
otherwise issuable.  The closing price for any day shall be the
last sale price, regular way, or, in case no such sale takes
place on such day, the average of the closing bid and asked
prices, regular way, in either case as reported in the principal
consolidated transaction reporting system with respect to
securities listed or admitted to trading on the New York Stock
Exchange or, if the Rights are not listed or admitted to trading
on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to
securities listed on the principal national securities exchange
on which the Rights are listed or admitted to trading or, if the
Rights are not listed or admitted to trading on any national
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
Preferred Shares (other than fractions which are integral
multiples of one one-thousandth of a Preferred Share) upon
exercise of the Rights or to distribute certificates which
evidence fractional Preferred Shares (other than fractions which
are integral multiples of one one-thousandth of a Preferred
Share).  Fractions of Preferred Shares in integral multiples of
one one-thousandth of a Preferred Share may, at the election of
the Company, be evidenced by depositary receipts, pursuant to an
appropriate agreement between the Company and a depositary
selected by it; provided, that such agreement shall provide that
the holders of such depositary receipts shall have all the
rights, privileges and preferences to which they are entitled as
beneficial owners of the Preferred Shares represented by such
depositary receipts.  In lieu of fractional Preferred Shares that
are not integral multiples of one one-thousandth of a Preferred
Share, the Company may pay to the registered holders of Right
Certificates at the time such Rights are exercised as herein
provided an amount in cash equal to the same fraction of the
current market value of one one-thousandth of a Preferred Share. 
For the purposes of this Section 14(b), the current market value
of one one-thousandth of a Preferred Share shall be one one-
thousandth of the closing price of a Preferred Share (as
determined pursuant to the second sentence of Section 11(d)(i)
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 Common Shares
upon exercise of the Rights or to distribute certificates which
evidence fractional Common Shares.  In lieu of fractional Common
Shares, the Company may pay to the registered holders of Right
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 Common Share.  For purposes of this
Section 14(c), the current market value of one Common Share shall
be the closing price of one Common Share (as determined pursuant
to the second sentence of Section 11(d)(i) hereof) for the
Trading Day immediately prior to the date of such exercise.
     (d)  The holder of a Right by the acceptance of the Right
expressly waives his right to receive any fractional Rights or
any fractional shares upon exercise of a Right (except as
provided above).

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

     Section 16.  Agreement of Right Holders.  Every holder of a
Right, by accepting the same, consents and agrees with the
Company and the Rights Agent and with every other holder of a
Right that:
     (a)  prior to the Distribution Date, the Rights will be
transferable only in connection with the transfer of the Common
Shares;
     (b)  after the Distribution Date, the Right Certificates are
transferable only on the registry books of the Rights Agent if
surrendered at the office of the Rights Agent designated for such
purposes, duly endorsed or accompanied by a proper instrument of
transfer and with appropriate forms and certificates fully
executed; 
     (c)  the Company and the Rights Agent may deem and treat the
person in whose name the Right Certificate (or, prior to the
Distribution Date, the associated Common Shares certificate) is
registered as the absolute owner thereof and of the Rights
evidenced thereby (notwithstanding any notations of ownership or
writing on the Right Certificates or the associated Common Shares
certificate made by anyone other than the Company or the Rights
Agent) for all purposes whatsoever, and neither the Company nor
the Rights Agent shall be affected by any notice to the contrary;
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 any 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.

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

     Section 18.  Concerning the Rights Agent.  The Company
agrees to pay to the Rights Agent reasonable compensation for all
services rendered by it hereunder and, from time to time, on
demand of the Rights Agent, its reasonable expenses and counsel
fees and other disbursements (including any taxes other than
income taxes) 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 negligence, bad faith or willful
misconduct on the part of the Rights Agent, for anything done or
omitted by the Rights Agent in connection with the acceptance and
administration of this Agreement, including the costs and
expenses of defending against any claim of liability arising,
directly or indirectly, therefrom.

     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 Right Certificate or certificate
for the Preferred Shares or Common Shares or for other securities
of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, direction,
consent, certificate, statement or other paper or document
believed by it to be genuine and to be signed, executed and,
where necessary, verified or acknowledged by the proper person or
persons, or otherwise upon the advice of counsel as set forth in
Section 20 hereof.

     Section 19.  Merger or Consolidation or Change of Name of
Rights Agent.  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
stock transfer or corporate trust business of the Rights Agent or
any successor Rights Agent, shall be the successor to the Rights
Agent under this Agreement without the execution or filing of any
paper or any further act on the part of any of the parties
hereto; provided, that such corporation would be eligible for
appointment as 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 Right Certificates shall have been countersigned but not
delivered, any such successor Rights Agent may adopt the
countersignature of the predecessor Rights Agent and deliver such
Right Certificates so countersigned; and in case at that time any
of the Right Certificates shall not have been countersigned, any
successor Rights Agent may countersign such Right Certificates
either in the name of the predecessor Rights Agent or in the name
of the successor Rights Agent; and in all such cases such Right
Certificates shall have the full force provided in the Right
Certificates and in this Agreement.

     In case at any time the name of the Rights Agent shall be
changed and at such time any of the Right Certificates shall have
been countersigned but not delivered, the Rights Agent may adopt
the countersignature under its prior name and deliver Right
Certificates so countersigned; and in case at that time any of
the Right Certificates shall not have been countersigned, the
Rights Agent may countersign such Right Certificates either in
its prior name or in its changed name; and in all such cases such
Right Certificates shall have the full force provided in the
Right 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 Right Certificates, by their
acceptance thereof, shall be bound:
     (a)  The Rights Agent may consult with legal counsel
satisfactory to it (who may be legal counsel for the Company),
and the opinion of such counsel shall be full and complete
authorization and protection to the Rights Agent, and the Rights
Agent shall incur no liability or responsibility to the Company
or to any holder of any Right Certificate in respect of 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 be proved or established by the Company
prior to taking or suffering or omitting 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 any one of the
Chairman of the Board, the Chief Executive Officer, any Vice
Chairman, the President, any Vice President, the Treasurer or the
Secretary of the Company and delivered to the Rights Agent; and
such certificate shall be full authorization to the Rights Agent
for any action taken, suffered or omitted in good faith by it
under the provisions of this Agreement in reliance upon such
certificate.
     (c)  The Rights Agent shall be liable hereunder to the
Company only for, and shall indemnify and hold harmless the
Company from and against, any and all losses, liabilities, costs,
damages and expenses (including attorneys' fees) arising out of
or in connection with the Rights Agent's 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 Right Certificates (except its countersigna-
ture thereof) or be required to verify the same, but all such
statements and recitals are and shall be deemed to have been made
by the Company only.
     (e)  The Rights Agent shall not be under any responsibility
in respect of the validity of this 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 Right
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 Right
Certificate; nor shall it be responsible for any change in the
exercisability of the Rights (including the Rights becoming void
pursuant to Section 7(e) hereof) or any adjustment in the terms
of the Rights (including the manner, method or amount thereof)
provided for in Section 3, 11, 13, 23 or 24, or the ascertaining
of the existence of facts that would require any such change or
adjustment (except with respect to the exercise of Rights
evidenced by Right Certificates after receipt of a certificate
furnished pursuant to Section 12 describing a change or
adjustment); nor shall it by any act hereunder be deemed to make
any representation or warranty as to the authorization or
reservation of any Preferred Shares or Common Shares to be issued
pursuant to this Agreement or any Right Certificate or as to
whether any Preferred Shares or Common Shares will, when issued,
be validly authorized and issued, fully paid and nonassessable.
     (f)  The Company agrees that it will perform, execute,
acknowledge and deliver or cause to be performed, executed,
acknowledged and delivered all such further and other acts,
instruments and assurances as may reasonably be required by the
Rights Agent for the carrying out or performing by the Rights
Agent of the provisions of this Agreement.
     (g)  The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties
hereunder from any one of the Chairman of the Board, the Chief
Executive Officer, any Vice Chairman, the President, any Vice
President, the Secretary or the 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 by it in good faith in accordance with instructions
of any such officer or for any delay in acting while waiting for
those instructions.  Any application by the Rights Agent for
written instructions from the Company may, at the option of the
Rights Agent, set forth in writing any action proposed to be
taken or omitted by the Rights Agent under this Agreement and the
date on and/or after which such action shall be taken or such
omission shall be effective.  The Rights Agent shall not be
liable for any action taken by, or omission of, the Rights Agent
in accordance with a proposal included in any such application on
or after the date specified in such application (which date shall
not be less than five Business Days after the date such
application is given, unless any such officer shall have
consented in writing to an earlier date) unless, prior to taking
any such action (or the effective date in the case of an
omission), the Rights Agent shall have received written
instructions in response to such application specifying the
action to be taken or omitted.
     (h)  The Rights Agent and any stockholder, director, officer
or employee of the Rights Agent may buy, sell or deal in any of
the Rights or other securities of the Company or its Subsidiaries
or become pecuniarily interested in any transaction in which the
Company or its Subsidiaries may be interested, or contract with
or lend money to the Company or its Subsidiaries 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 its Subsidiaries
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 reasonable care was
exercised in the selection and continued employment thereof.
     (j)  If, with respect to any Rights Certificate surrendered
to the Rights Agent for exercise, transfer, split up, combination
or exchange, 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, transfer, split
up, combination or exchange without first consulting with the
Company.
     (k)  The Rights Agent shall not be under any duty or
responsibility to ensure compliance with any applicable federal
or state securities laws in connection with the issuance,
transfer or exchange of Right Certificates.
     (l)  The Rights Agent shall be under no obligation to
institute any action, suit or legal proceeding or to take any
other action likely to involve expense unless the Company or one
or more holders of Right Certificates shall furnish the Rights
Agent with security and indemnity to its satisfaction for any
costs and expenses which may be incurred.
     (m)  The Rights Agent shall not be liable for failure to
perform any duties except as specifically set forth herein, and
no implied covenants or obligations shall be read into this
Agreement against the Rights Agent whose duties and obligations
are ministerial and shall be determined solely by the express
provisions hereof.

     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 30 days' notice in writing
mailed to the Company and to each transfer agent of the Common
Shares or Preferred Shares by registered or certified mail, and
to the holders of the Right Certificates by first-class mail. 
The Company may remove the Rights Agent or any successor Rights
Agent upon 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 Shares or Preferred Shares by
registered or certified mail, and to the holders of the Right
Certificates by first-class mail.  If the Rights Agent shall
resign or be removed or shall otherwise become incapable of
acting, the Company shall appoint a successor to the Rights
Agent.  If the Company shall fail to make such appointment within
a period of 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 Right Certificate (who shall, with such notice, submit his
Right Certificate for inspection by the Company), then the
registered holder of any Right 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 or bank
organized and doing business under the laws of the United States
or of any other state of the United States, which is authorized
under such laws to exercise corporate trust or stock transfer
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
million.  After appointment, the successor Rights Agent shall be
vested with the same powers, rights, duties and responsibilities
as if it had been originally named as Rights Agent without
further act or deed; but the predecessor Rights Agent shall
deliver and transfer to the successor Rights Agent any property
at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the
purpose.  Not later than the effective date of any such
appointment, the Company shall file notice thereof in writing
with the predecessor Rights Agent and each transfer agent of the
Common Shares or Preferred Shares, and mail a notice thereof in
writing to the registered holders of the Right 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 Right Certificates. 
Notwithstanding any of the provisions of this Agreement or of the
Rights to the contrary, the Company may, at its option, issue new
Right 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
Right Certificates made in accordance with the provisions of this
Agreement.
     Section 23.  Redemption.  
     (a)  The Board of Directors of the Company may, at its
option, at any time prior to such time as any Person becomes an
Acquiring Person, redeem all but not less than all the then
outstanding Rights at a redemption price of $.01 per Right,
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").  The redemption of the Rights by the Board of Directors
may be made effective at such time, on such basis and with such
conditions as the Board of Directors in its sole discretion may
establish.  If redemption of the Rights is to be effective as of
a future date, the Rights shall continue to be exercisable,
subject to Section 7 hereof, until the effective date of the
redemption, provided that nothing contained herein shall preclude
the Board of Directors from subsequently causing the Rights to be
redeemed at a date earlier than the previously scheduled
effective date of the redemption.  The Company may, at its
option, pay the Redemption Price in cash, Common Shares (based on
the current per share market price of the Common Shares 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 (or at the
effective time of such redemption established by the Board of
Directors of the Company pursuant to paragraph (a) of this
Section 23), and without any further action and without any
notice, the right to exercise the Rights will terminate and the
only right thereafter of the holders of Rights shall be to
receive the Redemption Price.  The Company shall promptly give
public notice of any such redemption; provided, however, that the
failure to give, or any defect in, any such notice shall not
affect the validity of such redemption.  Within 10 days after
such action of the Board of Directors ordering the redemption of
the Rights or, if later, the effectiveness of the redemption of
the Rights pursuant to paragraph (a) of this Section 23, the
Company shall mail a notice of redemption to all the holders of
the then outstanding Rights at their last addresses as they
appear upon the registry books of the Rights Agent or, prior to
the Distribution Date, on the registry books of the transfer
agent for the Common Shares.  Any notice which is mailed in the
manner herein provided shall be deemed given, whether or not the
holder receives the notice.  Each such notice of redemption will
state the method by which the payment of the Redemption Price
will be made.  The Company may, at its option, discharge all of
its obligations with respect to the Rights by (i) issuing a press
release announcing the manner of redemption of the Rights, (ii)
depositing with a bank or trust company having a capital and
surplus of at least $100,000,000, funds necessary for such
redemption, in trust, to be applied to the redemption of the
Rights so called for redemption and (iii) arranging for the
mailing of the Redemption Price to the registered holders of the
Rights; then, and upon such action, all outstanding Rights
Certificates shall be null and void without further action by the
Company.  Neither the Company nor any of its Affiliates or
Associates may redeem, acquire or purchase for value any Rights
at any time in any manner other than that specifically set forth
in this Section 23, in Section 24 hereof, or in connection with
the purchase of Common Shares prior to the Distribution Date.

     Section 24.  Exchange.  
     (a)  The Board of Directors of the Company may, at its
option, at any time after a Triggering Event, 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 Shares at an
exchange ratio of one Common Share per Right, appropriately
adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof (such exchange ratio
being hereinafter referred to as the "Exchange Ratio"). 
Notwithstanding the foregoing, the Board of Directors shall not
be empowered to effect such exchange at any time after any Person
(other than the Company, any Subsidiary of the Company, any
employee benefit plan of the Company or any such Subsidiary, or
any entity holding Common Shares for or pursuant to the terms of
any such plan), together with all Affiliates and Associates of
such Person, becomes the Beneficial Owner of 50% or more of the
Common Shares then outstanding.
     (b)  Immediately upon the action of the Board of Directors
of the Company ordering the exchange of any Rights pursuant to
paragraph (a) of this Section 24 and without any further action
and without any notice, the right to exercise such Rights shall
terminate and the only right thereafter of a holder of such
Rights shall be to receive that number of Common Shares equal to
the number of such Rights held by such holder multiplied by the
Exchange Ratio.  The Company shall promptly give public notice of
any such exchange; provided, however, that the failure to give,
or any defect in, such notice shall not affect the validity of
such exchange.  The Company promptly shall mail a notice of any
such exchange to all of the holders of such Rights at their last
addresses as they appear upon the registry books of the Rights
Agent.  Any notice which is mailed in the manner herein provided
shall be deemed given, whether or not the holder receives the
notice.  Each such notice of exchange will state the method by
which the exchange of the Common Shares for Rights will be
effected and, in the event of any partial exchange, the number of
Rights which will be exchanged.  Any partial exchange shall be
effected pro rata based on the number of Rights (other than
Rights which have become void pursuant to the provisions of
Section 7(e) hereof) held by each holder of Rights.
     (c)  In any exchange pursuant to this Section 24, the
Company, at its option, may substitute Preferred Shares (or
equivalent preferred shares, as such term is defined in Section
11(b) hereof) for Common Shares exchangeable for Rights, at the
initial rate of one one-thousandth of a Preferred Share (or
equivalent preferred share) for each Common Share, as
appropriately adjusted to reflect adjustments in the voting
rights of the Preferred Shares pursuant to the terms thereof, so
that the fraction of a Preferred Share delivered in lieu of each
Common Share shall have the same voting rights as one Common
Share.
     (d)  In the event that there shall not be sufficient Common
Shares or Preferred Shares issued but not outstanding or
authorized but unissued to permit any exchange of Rights as
contemplated in accordance with this Section 24, the Company
shall take all such action as may be necessary to authorize
additional Common Shares or Preferred Shares for issuance upon
exchange of the Rights.
     (e)  The Company shall not be required to issue fractions of
Common Shares or to distribute certificates which evidence
fractional Common Shares.  In lieu of such fractional Common
Shares, the Company shall pay to the registered holders of the
Right Certificates with regard to which such fractional Common
Shares would otherwise be issuable an amount in cash equal to the
same fraction of the current market value of a whole Common
Share.  For the purposes of this paragraph (e), the current
market value of a whole Common Share shall be the closing price
of a Common Share (as determined pursuant to the second sentence
of Section 11(d)(i) hereof) for the Trading Day immediately prior
to the date of exchange pursuant to this Section 24.

     Section 25.  Notice of Certain Events.  
     (a)  In case the Company shall propose at any time after the
Distribution Date (i) to pay any dividend payable in stock of any
class to the holders of its Preferred Shares or to make any other
distribution to the holders of its Preferred Shares (other than a
regular quarterly cash dividend), (ii) to offer to the holders of
its Preferred Shares rights or warrants to subscribe for or to
purchase any additional Preferred Shares or shares of stock of
any class or any other securities, rights or options, (iii) to
effect any reclassification of its Preferred Shares (other than a
reclassification involving only the subdivision of outstanding
Preferred Shares), (iv) to effect any consolidation or merger
into or with, 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 or more transactions, of 50% or more of
the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to, any other Person, (v) to effect the
liquidation, dissolution or winding up of the Company, or (vi) to
declare or pay any dividend on the Common Shares payable in
Common Shares or to effect a subdivision, combination or
consolidation of the Common Shares (by reclassification or
otherwise than by payment of dividends in Common Shares), then,
in each such case, the Company shall give to each holder of a
Right Certificate, in accordance with Section 26 hereof, a notice
of such proposed action, which shall specify the record date for
the purposes of such stock dividend, or distribution of rights or
warrants, or the date on which such reclassification, consoli-
dation, merger, sale, transfer, liquidation, dissolution or
winding up is to take place and the date of participation therein
by the holders of the Common Shares and/or Preferred Shares, 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 10 days prior to the record date for determining holders of
the Preferred Shares for purposes of such action, and in the case
of any such other action, at least 10 days prior to the date of
the taking of such proposed action or the date of participation
therein by the holders of the Common Shares and/or Preferred
Shares, whichever shall be the earlier.
     (b)  In case any of the events set forth in Section
11(a)(ii) hereof shall occur, then the Company shall, as soon as
practicable thereafter, give to each holder of a Right
Certificate, in accordance with Section 26 hereof, a notice of
the occurrence of such event, which notice shall describe such
event and the consequences of such event to holders of Rights
under Section 11(a)(ii) hereof.

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

     Section 27.  Supplements and Amendments.  The Company may
from time to time supplement or amend this Agreement without the
approval of any holders of Right Certificates in order to cure
any ambiguity, to correct or supplement any provision contained
herein which may be defective or inconsistent with any other
provisions herein, or to make any other provisions with respect
to the Rights which the Company may deem necessary or desirable,
any such supplement or amendment to be evidenced by a writing
signed by the Company and the Rights Agent; provided, however,
that from and after such time as any Person becomes an Acquiring
Person, this Agreement shall not be amended in any manner which
would adversely affect the interests of the holders of Rights.  

     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.  Benefits of This Agreement.  Nothing in this
Agreement shall be construed to give to any person or corporation
other than the Company, the Rights Agent and the registered
holders of the Right Certificates (and, prior to the Distribution
Date, the Common Shares) 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

      CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS
                            OF 
        SERIES C JUNIOR PARTICIPATING PREFERRED STOCK

                            OF

                  NALCO CHEMICAL COMPANY

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

     The undersigned duly authorized officers of Nalco Chemical
Company, a Delaware corporation (the "Corporation"), in
accordance with the provisions of Section 151 of the General
Corporation Law of the State of Delaware, DO HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of
Directors by the Restated Certificate of Incorporation of the
Corporation, the Board of Directors on June 20, 1996, at a
meeting duly called and held, adopted the following resolution
creating a series of 200,000 shares of Preferred Stock, par value
$1.00 per share, designated as Series C Junior Participating
Preferred Stock:

     RESOLVED, that pursuant to the authority granted to and
vested in the Board of Directors by the Amended and Restated
Certificate of Incorporation, as amended, of the Corporation, the
Board of Directors hereby creates a series of preferred stock,
par value $1.00 per share, of the Corporation (such preferred
stock being herein referred to as "Preferred Stock," which term
shall include any additional shares of preferred stock of the
same class heretofore or hereafter authorized to be issued by the
Corporation), consisting of 200,000 shares, and hereby fixes the
designation and the voting powers, preferences and relative,
participating, optional or other special rights, and the
qualifications, limitations or restrictions thereof, as follows:

     Section 1.  Designation and Amount.  There shall be a series
of Preferred Stock of the Corporation which shall be designated
as "Series C Junior Participating Preferred Stock," par value
$1.00 per share, (hereinafter called "Series C Preferred Stock"),
and the number of shares constituting such series shall be
200,000.  Such number of shares may be increased or decreased by
resolution of the Board of Directors and by the filing of a
certificate pursuant to the provisions of the General Corporation
Law of the State of Delaware stating that such increase or
reduction has been so authorized; provided, however, that no
decrease shall reduce the number of shares of Series C Preferred
Stock to a number less than that of the shares then outstanding
plus the number of shares of Series C Preferred Stock issuable
upon exercise of outstanding rights, options or warrants or upon
conversion of outstanding securities issued by the Corporation.

     Section 2.  Dividends and Distributions.

     (A)  Subject to the prior and superior rights of the holders
of any shares of any series of Preferred Stock ranking prior and
superior to the shares of Series C Preferred Stock with respect
to dividends, the holders of shares of Series C 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 to holders of record
on the last business day of March, June, September and December
in each year (each such date being referred to herein as a
"Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of a
share or fraction of a share of Series C Preferred Stock, in an
amount per share (rounded to the nearest cent) equal to the
greater of (a) $10.00 or (b) subject to the provision for
adjustment hereinafter set forth, 1,000 times the aggregate per
share amount of all cash dividends, and 1,000 times the aggregate
per share amount (payable in kind) of all non-cash dividends or
other distributions other than a dividend payable in shares of
Common Stock (hereinafter defined) or a subdivision of the
outstanding shares of Common Stock (by reclassification or
otherwise), declared on the common stock, par value $0.1875 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 C
Preferred Stock.  In the event the Corporation shall at any time
following September 1, 1996 (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 C Preferred Stock
were entitled immediately prior to such event under clause (b) of
the preceding sentence shall be adjusted by multiplying each 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 C Preferred Stock as provided in
paragraph (A) above at the time it declares a dividend or
distribution on the Common Stock (other than a dividend payable
in shares of Common Stock).

     (C)  No dividend or distribution (other than a dividend
payable in shares of Common Stock) shall be paid or payable to
the holders of shares of Common Stock unless, prior thereto, all
accrued but unpaid dividends to the date of such dividend or
distribution shall have been paid to the holders of shares of
Series C Preferred Stock.

     (D)  Dividends shall begin to accrue and be cumulative on
outstanding shares of Series C Preferred Stock from the Quarterly
Dividend Payment Date next preceding the date of issue of such
shares of Series C 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 C 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 C 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 C Preferred
Stock entitled to receive payment of a dividend or distribution
declared thereon, which record date shall be no more than 30 days
prior to the date fixed for the payment thereof.

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

     (A)  Subject to the provision for adjustment hereinafter set
forth, each one one-thousandth of a share of Series C Preferred
Stock shall entitle the holder thereof to one vote on all matters
submitted to a vote of the shareholders of the Corporation.  In
the event the Corporation shall at any time following September
1, 1996 (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 C 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 C Preferred Stock and the holders of
shares of Common Stock and any other capital stock of the
Corporation having general voting rights shall vote together as
one class on all matters submitted to a vote of shareholders of
the Corporation.

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

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

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

     (D)  Except as set forth herein, holders of Series C
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 C Preferred Stock as provided
in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on
shares of Series C 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 C 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 C Preferred Stock, except
     dividends paid ratably on the Series C 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 C 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 C Preferred Stock;
     or

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

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

     Section 5.  Reacquired Shares.  Any shares of Series C
Preferred Stock purchased or otherwise acquired by the
Corporation in any manner whatsoever shall be retired and
cancelled promptly after the acquisition thereof.  All such
shares shall upon their cancellation become authorized but
unissued shares of Preferred Stock and may be reissued as part of
a new series of Preferred Stock to be created by resolution or
resolutions of the Board of Directors, subject to the conditions
and restrictions on issuance set forth herein.

     Section 6.  Liquidation, Dissolution or Winding Up. 

     (A)  Upon any voluntary liquidation, 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 C
Preferred Stock unless, prior thereto, the holders of shares of
Series C Preferred Stock shall have received $10.00 per share,
plus an amount equal to accrued and unpaid dividends and
distributions thereon, whether or not declared, to the date of
such payment (the "Series C Liquidation Preference").  Following
the payment of the full amount of the Series C Liquidation
Preference, no additional distributions shall be made to the
holders of shares of Series C 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 C Liquidation
Preference by (ii) 1,000 (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 C
Liquidation Preference and the Common Adjustment in respect of
all outstanding shares of Series C Preferred Stock and Common
Stock, respectively, holders of Series C 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, on a per share basis, of the Adjustment Number to 1
with respect to such Preferred Stock and Common Stock, on a per
share basis, respectively.

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

     (C)  In the event the Corporation shall at any time
following September 1, 1996 (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 C 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
1,000 times the aggregate amount of stock, securities, cash
and/or any other property (payable in kind), as the case may be,
into which or for which each share of Common Stock is changed or
exchanged.  In the event the Corporation shall at any time (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 C 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.  Redemption.  The shares of a Series C Preferred
Stock shall not be redeemable by the Corporation.  The preceding
sentence shall not limit the ability of the Corporation to
purchase or otherwise deal in such shares of stock to the extent
permitted by law.

     Section 9.  Ranking.  The Series C Preferred Stock shall
rank junior to all other series of the Corporation's preferred
stock (whether with or without par value) as to the payment of
dividends and the distribution of assets, unless the terms of any
such series shall provide otherwise.

     Section 10.  Amendment.  The Restated Certificate of
Incorporation of the Corporation shall not be amended in any
manner which would materially alter or change the powers,
preferences or special rights of the Series C 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
C Preferred Stock, voting separately as a class.

     Section 11.  Fractional Shares.  Series C Preferred Stock
may be issued in fractions of a share which shall entitle the
holder, in proportion to such holder's fractional shares, to
exercise voting rights, receive dividends, participate in
distributions and to have the benefit of all other rights of
holders of Series C Preferred Stock.

     3.   The Restated Certificate of Incorporation is amended so
that the designation and number of shares of the class and series
acted upon in the forgoing resolution, and the relative rights,
preferences and limitations of such class and series, are as
stated in the resolution.

corporate seal to be hereunto affixed and this Certificate to be
signed by the undersigned corporate officer and the same to be

     Upon the occurrence of a Triggering Event, if the Rights

an Acquiring Person or an Affiliate or Associate of any such
Acquiring Person (as such terms are defined in the Rights
Agreement), (ii) under certain circumstances specified in the
Rights Agreement, a transferee of any such Acquiring Person,
Associate or Affiliate, or (iii) under certain circumstances
specified in the Rights Agreement, a transferee of a person who,
after such transfer, became an Acquiring Person, or an Affiliate
or Associate of an Acquiring Person, such Rights shall become
null and void and no holder hereof shall have any right with
respect to such Rights from and after the occurrence of any such
Triggering Event.

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

     This Right Certificate is subject to all of the terms,
provisions and conditions of the Rights Agreement, which terms,
provisions and conditions are hereby incorporated herein by
reference and made a part hereof and to which Rights Agreement
reference is hereby made for a full description of the rights,

of the Rights Agreement are available upon written request to the
Rights Agent.

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

     Subject to the provisions of the Rights Agreement, the
Rights evidenced by this Certificate may be redeemed by the
Company at its option at a redemption price of $.01 per Right at
any time prior to the earlier of the close of business on (i) the
Shares Acquisition Date and (ii) the Final Expiration Date.

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

     No holder of this Right Certificate, as such, shall be
entitled to vote or receive dividends or be deemed for any
purpose the holder of Preferred Shares 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 shareholder of the Company or any right to
vote for the election of directors or upon any matter submitted
to shareholders at any meeting thereof; or to give or withhold
consent to any corporate action; or to receive notice of meetings
or other actions affecting shareholders (except as provided in
the Rights Agreement); or to receive dividends or subscription
rights, or otherwise, until the Right or Rights evidenced by this
Right Certificate shall have been exercised as provided in the
Rights Agreement.

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

                     SUMMARY OF RIGHTS PLAN
                     ----------------------

     On June 20, 1996, the Board of Directors of Nalco Chemical
Company (the "Company") declared a dividend distribution of one
Right for each outstanding share of common stock, par value
$0.1875 per share (the "Common Stock"), of the Company to
shareholders of record at the close of business on September 1,
1996 (the "Record Date").  Except as described below, each Right,
when exercisable, entitles the registered holder to purchase from
the Company one one-thousandth of a share of Series C Junior
Participating Preferred Stock, par value $1.00 per share, (the
"Preferred Stock"), at a price of $125.00 per one one-thousandth
of a share (the "Purchase Price"), subject to adjustment.  The
description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and First
Chicago Trust Company, as Rights Agent.

     Initially, the Rights will be attached to all Common Stock
certificates representing shares then outstanding, and no
separate Right certificates will be distributed.  Until the
earlier to occur of (i) 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 15% or more of the outstanding
shares of Common Stock (the "Shares Acquisition Date") or (ii) 15
business days (or such later date as may be determined by action
of the Board of Directors of the Company (the "Board of
Directors") prior to the time that any person becomes an
Acquiring Person) following the commencement of (or a public
announcement of an intention to make) a tender or exchange offer
if, upon consummation thereof, such person or group would be the 
beneficial owner of 15% or more of such outstanding shares of
Common Stock (the earlier of such dates being called the
"Distribution Date"), the Rights will be evidenced by the Common
Stock certificates, together with a copy of the Summary of Rights
Plan and not by separate certificates.

     The Rights Agreement also provides that, until the
Distribution Date, the Rights will be transferred with and only
with the Common Stock.  Until the Distribution Date (or earlier
redemption, expiration or termination of the Rights), the
transfer of any certificates for Common Stock, with or without a
copy of this Summary of Rights Plan, will also constitute the
transfer of the Rights associated with the Common Stock
represented by such certificates.  As soon as practicable
following the Distribution Date, separate certificates evidencing
the Rights ("Right Certificates") will be mailed to holders of
record of the Common Stock as of the close of business on the
Distribution Date and, thereafter, such separate Right
Certificates alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date
and will expire at the earliest of (i) August 31, 2006 (the
"Final Expiration Date"), (ii) the redemption of the Rights by
the Company as described below and (iii) the exchange of all
Rights for Common Stock as described below.

     In the event that any person (other than the Company, its
affiliates or any person receiving newly-issued shares of Common
Stock directly from the Company) becomes the beneficial owner of
15% or more of the then outstanding shares of Common Stock, each
holder of a Right will thereafter have the right to receive, upon
exercise at the then current exercise price of the Right, 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 Rights Agreement contains an
exemption for any issuance of Common Stock by the Company
directly to any person (for example, in a private placement or an
acquisition by the Company in which Common Stock is used as
consideration), even if that person would become the beneficial
owner of 15% or more of the Common Stock, provided that such
person does not acquire any additional shares of Common Stock.

     In the event that, at any time following the Shares
Acquisition Date, the Company is acquired in a merger or other
business combination transaction or 50% or more of the Company's
assets or earning power are sold, proper provision will be made
so that each holder of a Right will thereafter have the right to
receive, upon exercise at the then-current exercise price of the
Right, common stock of the acquiring or surviving company having
a value equal to two times the exercise price of the Right.

     Notwithstanding the foregoing, following the occurrence of
any of the events set forth in the preceding two paragraphs (the
"Triggering Events"), any Rights that are, or (under certain
circumstances specified in the Rights Agreement) were,
beneficially owned by any Acquiring Person will immediately
become null and void.

     The Purchase Price payable, and the number of shares 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, among other circumstances, in the event
of a stock dividend on, or a subdivision, split, combination,
consolidation or reclassification of, the Preferred Stock or the
Common Stock, or a reverse split of the outstanding shares of
Preferred Stock or the Common Stock.

     At any time after the acquisition by a person or group of
affiliated or associated persons of beneficial ownership of 15%
or more of the outstanding Common Stock and prior to the
acquisition by such person or group of 50% or more of the
outstanding Common Stock, the Board of Directors may exchange the
Rights (other than Rights owned by such person or group, which
have become void), in whole or in part, at an exchange ratio of
one share of Common Stock per Right (subject to adjustment).  

     With certain exceptions, no adjustment in the Purchase Price
will be required until cumulative adjustments require an
adjustment of at least 1% in the Purchase Price.  The Company
will not be required to issue fractional shares of Preferred
Stock or Common Stock (other than fractions in multiples of one
one-thousandths of a share of Preferred Stock) and, in lieu
thereof, an adjustment in cash may be made based on the market
price of the Preferred Stock or Common Stock on the last trading
date prior to the date of exercise.

     At any time after the date of the Rights Agreement until the
time that a person becomes an Acquiring Person, the Board of
Directors may redeem the Rights in whole, but not in part, at a
price of $.01 per Right (the "Redemption Price"), which may (at
the option of the Company) be paid in cash, shares of Common
Stock or other consideration deemed appropriate by the Board of
Directors.  Upon the effectiveness of any 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 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.

     The provisions of the Rights Agreement may be amended by the
Company, except that any amendment adopted after the time that a
person becomes an Acquiring Person may not adversely affect the
interests of holders of Rights.

     As of May 31, 1996, there were 67,370,313 shares of
Common Stock outstanding.  Each outstanding share of Common Stock 
on September 1, 1996 will receive one Right.  Two hundred thousand
(200,000) shares of Preferred Stock will be reserved for issuance 
in the event of exercise of the Rights.

     The Rights have certain anti-takeover effects.  The Rights
will cause substantial dilution to a person or group that
attempts to acquire the Company without conditioning the offer on
the Rights being redeemed or a substantial number of Rights being
acquired, and under certain circumstances the Rights beneficially
owned by such a person or group may become void.  The Rights
should not interfere with any merger or other business
combination approved by the Board of Directors because, if the
Rights would become exercisable as a result of such merger or
business combination, the Board of Directors may, at its option,
at any time prior to the time that any Person becomes an
Acquiring Person, redeem all (but not less than all) of the then
outstanding Rights at the Redemption Price.

     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.  This summary description of
the Rights does not purport to be complete and is qualified in
its entirety by reference to the Rights Agreement.


        CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS
                               OF 
           SERIES C JUNIOR PARTICIPATING PREFERRED STOCK

                               OF

                      NALCO CHEMICAL COMPANY

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

     The undersigned duly authorized officers of Nalco Chemical
Company, a Delaware corporation (the "Corporation"), in
accordance with the provisions of Section 151 of the General
Corporation Law of the State of Delaware, DO HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of
Directors by the Restated Certificate of Incorporation of the
Corporation, the Board of Directors on June 20, 1996, at a
meeting duly called and held, adopted the following resolution
creating a series of 200,000 shares of Preferred Stock, par value
$1.00 per share, designated as Series C Junior Participating
Preferred Stock:

     RESOLVED, that pursuant to the authority granted to and
vested in the Board of Directors by the Amended and Restated
Certificate of Incorporation, as amended, of the Corporation, the
Board of Directors hereby creates a series of preferred stock,
par value $1.00 per share, of the Corporation (such preferred
stock being herein referred to as "Preferred Stock," which term
shall include any additional shares of preferred stock of the
same class heretofore or hereafter authorized to be issued by the
Corporation), consisting of 200,000 shares, and hereby fixes the
designation and the voting powers, preferences and relative,
participating, optional or other special rights, and the
qualifications, limitations or restrictions thereof, as follows:

     Section 1.  Designation and Amount.  There shall be a series
of Preferred Stock of the Corporation which shall be designated
as "Series C Junior Participating Preferred Stock," par value
$1.00 per share, (hereinafter called "Series C Preferred Stock"),
and the number of shares constituting such series shall be
200,000.  Such number of shares may be increased or decreased by
resolution of the Board of Directors and by the filing of a
certificate pursuant to the provisions of the General Corporation
Law of the State of Delaware stating that such increase or
reduction has been so authorized; provided, however, that no
decrease shall reduce the number of shares of Series C Preferred
Stock to a number less than that of the shares then outstanding
plus the number of shares of Series C Preferred Stock issuable
upon exercise of outstanding rights, options or warrants or upon
conversion of outstanding securities issued by the Corporation.

     Section 2.  Dividends and Distributions.

     (A)  Subject to the prior and superior rights of the holders
of any shares of any series of Preferred Stock ranking prior and
superior to the shares of Series C Preferred Stock with respect
to dividends, the holders of shares of Series C 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 to holders of record
on the last business day of March, June, September and December
in each year (each such date being referred to herein as a
"Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of a
share or fraction of a share of Series C Preferred Stock, in an
amount per share (rounded to the nearest cent) equal to the
greater of (a) $10.00 or (b) subject to the provision for
adjustment hereinafter set forth, 1,000 times the aggregate per
share amount of all cash dividends, and 1,000 times the aggregate
per share amount (payable in kind) of all non-cash dividends or
other distributions other than a dividend payable in shares of
Common Stock (hereinafter defined) or a subdivision of the
outstanding shares of Common Stock (by reclassification or
otherwise), declared on the common stock, par value $0.1875 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 C
Preferred Stock.  In the event the Corporation shall at any time
following September 1, 1996 (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 C Preferred Stock
were entitled immediately prior to such event under clause (b) of
the preceding sentence shall be adjusted by multiplying each 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 C Preferred Stock as provided in
paragraph (A) above at the time it declares a dividend or
distribution on the Common Stock (other than a dividend payable
in shares of Common Stock).

     (C)  No dividend or distribution (other than a dividend
payable in shares of Common Stock) shall be paid or payable to
the holders of shares of Common Stock unless, prior thereto, all
accrued but unpaid dividends to the date of such dividend or
distribution shall have been paid to the holders of shares of
Series C Preferred Stock.

     (D)  Dividends shall begin to accrue and be cumulative on
outstanding shares of Series C Preferred Stock from the Quarterly
Dividend Payment Date next preceding the date of issue of such
shares of Series C 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 C 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 C 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 C Preferred
Stock entitled to receive payment of a dividend or distribution
declared thereon, which record date shall be no more than 30 days
prior to the date fixed for the payment thereof.

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

     (A)  Subject to the provision for adjustment hereinafter set
forth, each one one-thousandth of a share of Series C Preferred
Stock shall entitle the holder thereof to one vote on all matters
submitted to a vote of the shareholders of the Corporation.  In
the event the Corporation shall at any time following September
1, 1996 (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 C 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 C Preferred Stock and the holders of
shares of Common Stock and any other capital stock of the
Corporation having general voting rights shall vote together as
one class on all matters submitted to a vote of shareholders of
the Corporation.

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

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

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

     (D)  Except as set forth herein, holders of Series C
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 C Preferred Stock as provided
in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on
shares of Series C 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 C 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 C Preferred Stock, except
     dividends paid ratably on the Series C 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 C 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 C Preferred Stock;
     or

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

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

     Section 5.  Reacquired Shares.  Any shares of Series C
Preferred Stock purchased or otherwise acquired by the
Corporation in any manner whatsoever shall be retired and
cancelled promptly after the acquisition thereof.  All such
shares shall upon their cancellation become authorized but
unissued shares of Preferred Stock and may be reissued as part of
a new series of Preferred Stock to be created by resolution or
resolutions of the Board of Directors, subject to the conditions
and restrictions on issuance set forth herein.

     Section 6.  Liquidation, Dissolution or Winding Up. 

     (A)  Upon any voluntary liquidation, 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 C
Preferred Stock unless, prior thereto, the holders of shares of
Series C Preferred Stock shall have received $10.00 per share,
plus an amount equal to accrued and unpaid dividends and
distributions thereon, whether or not declared, to the date of
such payment (the "Series C Liquidation Preference").  Following
the payment of the full amount of the Series C Liquidation
Preference, no additional distributions shall be made to the
holders of shares of Series C 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 C Liquidation
Preference by (ii) 1,000 (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 C
Liquidation Preference and the Common Adjustment in respect of
all outstanding shares of Series C Preferred Stock and Common
Stock, respectively, holders of Series C 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, on a per share basis, of the Adjustment Number to 1
with respect to such Preferred Stock and Common Stock, on a per
share basis, respectively.

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

     (C)  In the event the Corporation shall at any time
following September 1, 1996 (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 C 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
1,000 times the aggregate amount of stock, securities, cash
and/or any other property (payable in kind), as the case may be,
into which or for which each share of Common Stock is changed or
exchanged.  In the event the Corporation shall at any time (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 C 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.  Redemption.  The shares of a Series C Preferred
Stock shall not be redeemable by the Corporation.  The preceding
sentence shall not limit the ability of the Corporation to
purchase or otherwise deal in such shares of stock to the extent
permitted by law.

     Section 9.  Ranking.  The Series C Preferred Stock shall
rank junior to all other series of the Corporation's preferred
stock (whether with or without par value) as to the payment of
dividends and the distribution of assets, unless the terms of any
such series shall provide otherwise.

     Section 10.  Amendment.  The Restated Certificate of
Incorporation of the Corporation shall not be amended in any
manner which would materially alter or change the powers,
preferences or special rights of the Series C 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
C Preferred Stock, voting separately as a class.

     Section 11.  Fractional Shares.  Series C Preferred Stock
may be issued in fractions of a share which shall entitle the
holder, in proportion to such holder's fractional shares, to
exercise voting rights, receive dividends, participate in
distributions and to have the benefit of all other rights of
holders of Series C Preferred Stock.

     3.   The Restated Certificate of Incorporation is amended so
that the designation and number of shares of the class and series
acted upon in the forgoing resolution, and the relative rights,
preferences and limitations of such class and series, are as
stated in the resolution.


     IN WITNESS WHEREOF, Nalco Chemical Company has caused its
corporate seal to be hereunto affixed and this Certificate to be
signed by the undersigned corporate officer and the same to be
attested by its Corporate Secretary, this 21st day of June, 1996.

      RESOLVED, that the Bylaws of the Corporation be, and they hereby are, 
amended by amending and restating Article II, Section 5 to read as set 
forth below (with deletions shown in double brackets and additions in 
double carets):

           Section 5.  Record Date.  In order that the Corporation may

      meeting of stockholders or any adjournment thereof, [[or to express 
      consent to corporate action in writing without a meeting,]] or

      allotment of any rights, or entitled to exercise any rights in 
      respect of any change, conversion or exchange of stock or for the 
      purpose of any other lawful action <<(other than action by written

      which shall not be more than 60 or less than 10 days before the date 
      of such meeting, nor more than 60 days prior to any other action.

      RESOLVED, that the Bylaws of the Corporation be, and they hereby are,

      majority of the <<votes of all>> outstanding shares of capital stock 
      [[entitled to vote at the meeting]], represented in person or by 
      proxy, shall constitute a quorum at a meeting of stockholders.  In 
      the absence of a quorum, a meeting may be adjourned from time to time 
      without notice to the stockholders.

      RESOLVED, that the Bylaws of the Corporation be, and they hereby are, 
amended by amending and restating Article II, Sections 9 and 10 to read as 
set forth below (with deletions shown in double brackets and additions in 
double carets):

           Section 9.  Notice of Stockholder Business at Annual Meeting.  
      At an annual meeting of the stockholders, only such business shall be 
      conducted as shall have been brought before the meeting (a) by or at 
      the direction of the Board of Directors or (b) by any stockholder of 
      the Corporation who complies with the notice procedures set forth in 
      this Section 9.  For business to be properly brought before an annual 
      meeting by a stockholder, the stockholder must have given timely 
      notice thereof in writing to the Secretary of the Corporation.  To be 
      timely, a stockholder's notice must be delivered to or mailed and 
      received at the principal executive offices of the Corporation, not 
      less than [[30]] <<90>> days [[nor more than 60 days]] prior to the 
      <<anniversary date of the prior year's annual>> meeting[[; provided, 
      however, that in the event that less than 40 days' notice or prior 
      public disclosure of the date of the meeting is given or made to 
      stockholders, notice by the stockholder to be timely must be received 
      not later than the close of business on the tenth day following the 
      day on which such notice of the date of the annual meeting was mailed 
      or such public disclosure was made]].  A stockholder's notice to the 
      Secretary shall set forth as to each matter the stockholder proposes 
      to bring before the annual meeting (a) a brief description of the 
      business desired to be brought before the annual meeting and the 
      reasons for conducting such business at the annual meeting, (b) the 
      name and address, as they appear on the Corporation's books, of the 
      stockholder proposing such business, (c) the class and number of 
      shares of the Corporation which are beneficially owned by the 
      stockholder and (d) any material interest of the stockholder in such 
      business.  Notwithstanding anything in these By-laws to the contrary, 
      no business shall be conducted at an annual meeting except in 
      accordance with the procedures set forth in this Section 9.  The 
      Chairman of an annual meeting shall, if the facts warrant, determine 
      and declare to the meeting that business was not properly brought 
      before the meeting and in accordance with the provisions of this 
      Section 9, and if he should so determine, he shall so declare to the 
      meeting and any such business not properly brought before the meeting 
      shall not be transacted.

           Section 10.  <<Required>> Vote [[at Meetings]]. [[When a quorum 
      is present at any meeting, the vote of the holders of a majority of 
      the stock having voting power present in person or represented by 
      proxy shall decide any question brought before such meeting, unless]] 
      <<Unless>> the question is one upon which by express provision of the 
      [[statutes]] <<Delaware General Corporation Law,>> [[or of]] the 
      certificate of incorporation <<or these Bylaws>>[[,]] a different 
      vote is required <<(>>in which case such express provision shall 
      govern and control the decision of such question<<), action by the 
      stockholders of the Corporation shall require (a) with respect to the 
      election of directors at a meeting of stockholders, a plurality of 
      the votes of the shares present in person or represented by proxy at 
      the meeting and entitled to vote on the election of directors, (b) 
      with respect to any other matter which is to be decided by 
      stockholders at a meeting of stockholders and which matter has 
      received the prior approval or recommendation of the Corporation's 
      Board of Directors, the affirmative vote of holders of shares 
      constituting a majority of the votes cast with respect to such 
      matter, or (c) with respect to any other matter, the affirmative vote 
      of holders of shares constituting a majority of the voting power of 
      all of the Corporation's outstanding shares>>.


      RESOLVED, that the Bylaws of the Corporation be, and they hereby are, 
amended by amending and restating Article II, Section 12 to read as set 
forth below (with deletions shown in double brackets and additions in 
double carets):

           Section 12.  [[(a)]] Consent Without a Meeting.  <<(a)>> 
      Whenever the vote of stockholders at a meeting thereof is required or 
      permitted to be taken for or in connection with any corporate action 
      by any provision of the statutes, the meeting and vote of 
      stockholders may be dispensed with if the certificate of 
      incorporation authorizes the action to be taken with the written 
      consent of the holders of less than all of the stock who would have 
      been entitled to vote upon the action if a meeting were held, on the 
      written consent of the stockholders having not less than such 
      percentage of the number of votes as may be authorized in the 
      certificate of incorporation; provided that in no case shall the 
      written consent be by the holders of stock having less than the 
      minimum percentage of the vote required by statute for the proposed 
      corporate action, and provided that prompt notice must be given to 
      all stockholders of the taking of corporate action without a meeting. 

           (b)  The record date for determining stockholders entitled to 
      express consent to corporate action in writing without a meeting 
      shall be fixed by the Board of Directors.  Any stockholder of record 
      seeking to have the stockholders authorize or take corporate action 
      by written consent without a meeting shall, by written notice to the 
      Secretary, request the Board of Directors to fix a record date.  Upon 
      receipt of such a request, the Secretary shall place such request 
      before the Board of Directors at its next regularly scheduled 
      meeting, provided, however, that if the stockholder represents in 
      such request that he intends, and is prepared, to commence a consent 
      solicitation as soon as is permitted by the Securities Exchange Act 
      of 1934, as amended, and the regulations thereunder and other 
      applicable law, the Secretary shall as promptly as practicable call a 
      special meeting of the Board of Directors, which meeting shall be 
      held as promptly as practicable <<but in all events within ten days 
      after the date on which the stockholder's request was received>>.  At 
      such regular or special meeting, the Board of Directors shall fix a 
      record date as provided in [[Article II, Section 6 of these By-laws 
      and]] Section 213([[a]]<<b>>) (or its successor provision) of the 
      Delaware General Corporation Law.  Should the Board of Directors fail 
      to fix a record date as provided for in this Section [[13]] <<12>>, 
      [[then the record date shall be the day on which the first written 
      consent is expressed]] <<the record date for determining the 
      stockholders entitled to consent to corporate action in writing 
      without a meeting, when no prior action by the Board of Directors is 
      required by applicable law, shall be the first date on which a signed 
      written consent setting forth the action taken or proposed to be 
      taken is delivered to the Corporation by delivery to its registered 
      office in the State of Delaware, its principal place of business, or 
      an officer or agent of the Corporation having custody of the records 
      in which proceedings of stockholders meetings are recorded, to the 
      attention of the Secretary of the Corporation.  Delivery shall be by 
      hand or by certified or registered mail, return receipt requested.  
      If no record date has been fixed by the Board of Directors and prior 
      action by the Board of Directors is required by applicable law, the 
      record date for determining stockholders entitled to consent to 
      corporate action in writing without a meeting shall be at the close 
      of business on the date on which the Board of Directors adopts the 
      resolution taking such prior action>>.

           (c)        In the event of the delivery to the Corporation of 
      written consents purporting to represent the requisite voting power 
      to authorize or take corporate action and/or related revocations, the 
      Secretary of the Corporation shall provide for the safekeeping of 
      such consents and revocations and shall, as promptly as practicable, 
      engage nationally recognized independent inspectors of elections for 
      the purpose of promptly performing a ministerial review of the 
      validity of the consents and revocations.  No action by written 
      consent and without a meeting shall be effective until such 
      inspectors have completed their review, determined that the requisite 
      number of valid and unrevoked consents has been obtained to authorize 
      or take the action specified in the consents, and certified such 
      determination for entry in the records of the Corporation kept for 
      the purpose of recording the proceedings of meeting of stockholders.


      RESOLVED, that the Bylaws of the Corporation be, and they hereby are, 
amended by amending and restating Article III, Section 3 to read as set 
forth below (with deletions shown in double brackets and additions in 
double carets):

           Section 3.  Notice of Stockholder Nominees.  Only persons who 
      are nominated in accordance with the procedures set forth in these 
      By-laws shall be eligible for election as directors.  Nominations of 
      persons for election to the Board of Directors of the Corporation may 
      be made at a meeting of stockholders (a) by or at the direction of 
      the Board of Directors or (b) by any stockholder of the Corporation 
      entitled to vote for the election of Directors at the meeting who 
      complies with the notice procedures set forth in this Section 3.  
      Such nominations, other than those made by or at the direction of the 
      Board of Directors, shall be made pursuant to timely notice in 
      writing to the Secretary of the Corporation.  To be timely, a 
      stockholder's notice shall be delivered to or mailed and received at 
      the principal executive offices of the Corporation not less than 
      [[30]] <<90>> days [[nor more than 60 days]] prior to the 
      <<anniversary date of the prior year's annual>> meeting[[; provided, 
      however, that in the event that less than 40 days' notice or prior 
      public disclosure of the date of the meeting is given or made to 
      stockholders, notice by the stockholder to be timely must be so 
      received not later than the close of business on the tenth day 
      following the day on which such notice of the date of the meeting was 
      mailed or such public disclosure was made]].  Such stockholder's 
      notice shall set forth (a) as to each person whom the stockholder 
      proposes to nominate for election or re-election as a director, all 
      information relating to such person that is required to be disclosed 
      in solicitations of proxies for election of directors, or is 
      otherwise required, in each case pursuant to Regulation 14A under the 
      Securities Exchange Act of 1934, as amended (including such person's 
      written consent to being named in the proxy statement as a nominee 
      and to serving as a director if elected); and (b) as to the 
      stockholder giving the notice (i) the name and address, as they 
      appear on the Corporation's books, of such stockholder and (ii) the 
      class and number of shares of the Corporation which are beneficially 
      owned by such stockholder.  At the request of the Board of Directors 
      any person nominated by the Board of Directors for election as a 
      director shall furnish to the Secretary of the Corporation that 
      information required to be set forth in a stockholder's notice of 
      nomination which pertains to the nominee.  No person shall be 
      eligible for election as a director of the Corporation unless 
      nominated in accordance with the procedures set forth in the By-laws. 
      The Chairman of the meeting shall, if the facts warrant, determine 
      and declare to the meeting that a nomination was not made in 
      accordance with the procedures prescribed by these By-laws, and if he 
      should so determine, he shall so declare to the meeting and the 
      defective nomination shall be disregarded.




          NALCO CHEMICAL COMPANY REPLACES EXPIRING SHAREHOLDER 
                      RIGHTS PLAN AND AMENDS BYLAWS


Naperville, Ill., June 20, 1996 -- Nalco Chemical Company (NYSE: NLC) 
announced today that its Board of Directors has adopted a new shareholder 
rights plan.  The plan replaces the Company's existing shareholder rights 
plan which expires on August 31, 1996.  The Company also announced that its 
Board of Directors has adopted certain amendments to the Company's bylaws.

      Commenting on the shareholder rights plan, Nalco Chairman and Chief 
Executive Officer E.J. Mooney stated that, "The Rights are not being 
distributed in response to any specific effort to acquire control of the 
Company.  More than 1700 other companies have similar plans."

      Under the shareholder rights plan, each stockholder of record on 
September 1, 1996 will receive a distribution of one Right for each share 
of the Company's outstanding common stock.  The Rights distribution is not 
taxable to shareholders.  Initially, the Rights are represented by the 
Company's common stock certificates and are not exercisable.  

      The new Rights will be exercisable only if a person acquires, or 
announces a tender offer which would result in, ownership of 15 percent or 
more of the Company's common stock.  The exercise price will be $125 per 
Right, subject to adjustment.  If a person acquires beneficial ownership of 
15 percent or more of the Company's common stock, all holders of Rights 
other than the acquiring person will be entitled to purchase the Company's 
common stock at half price.  The Company may redeem the Rights at $.01 per 
Right at any time before someone becomes a 15 percent beneficial owner.
