          Agreement, dated as of August 4, 2000, between Hercules Incorporated,
a Delaware corporation (the "COMPANY"), and ChaseMellon Shareholder Services,
L.L.C., a New Jersey limited liability company, as rights agent (the "RIGHTS
AGENT").

          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 on August 14, 2000 (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 earliest of the Distribution Date,
the Redemption Date and the Final Expiration Date (as such terms are hereinafter
defined).

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

          SECTION 1. DEFINITIONS.  For purposes of this Agreement, the following
terms have the meanings indicated:

          (a) "ACQUIRING PERSON" shall mean any Person who or which, together
with all Affiliates and Associates of such Person, shall be the Beneficial Owner
of 10% or more of the Common Shares of the Company then outstanding, but shall
not include the Company, any Subsidiary of the Company, any employee benefit
plan of the Company or any Subsidiary of the Company, or any entity holding
Common Shares for or pursuant to the terms of any such plan. Notwithstanding the
foregoing, no Person shall become an "Acquiring Person" (i) as the result of an
acquisition of Common Shares by the Company which, by reducing the number of
Com-

<PAGE>

mon Shares of the Company outstanding, increases the proportionate number of
Common Shares of the Company beneficially owned by such Person to 10% or more of
the Common Shares of the Company then outstanding; PROVIDED, HOWEVER, that, if a
Person shall become the Beneficial Owner of 10% or more of the Common Shares of
the Company then outstanding by reason of share purchases by the Company and
shall, after such share purchases by the Company, become the Beneficial Owner of
any additional Common Shares of the Company, then such Person shall be deemed to
be an "Acquiring Person," or (ii) if as of the date of this Agreement such
Person beneficially owned 10% or more of the Common Shares of the Company then
outstanding; PROVIDED, HOWEVER, that if such Person becomes the beneficial owner
of any additional Common Shares of the Company after the date of this Agreement,
then such Person shall 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 (a), has become such
inadvertently, and such Person divests as promptly as practicable 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 (a),
then such Person shall not be deemed to be an "Acquiring Person" for any
purposes of this Agreement.

          (b) "AFFILIATE" shall have the meaning ascribed to such term in Rule
12b-2 of the General Rules and Regulations under the Exchange Act as in effect
on the date of this Agreement.

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

                                      -2-

          (d) A Person shall be deemed the "Beneficial Owner" of and shall be
deemed to "beneficially own" any securities:

          (i) which such Person or any of such Person's Affiliates or Associates
     beneficially owns, directly or indirectly;

          (ii) which such Person or any of such Person's Affiliates or
     Associates has (A) the right to acquire (whether such right is exercisable
     immediately or only after the passage of time) pursuant to any agreement,
     arrangement or understanding (other than customary 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; or (B) the right to vote pursuant to any
     agreement, arrangement or understanding; PROVIDED, HOWEVER, that a Person
     shall not be deemed the Beneficial Owner of, or to beneficially own, any
     security 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

                                      -3-
<PAGE>

          (iii) which are beneficially owned, directly or indirectly, by any
     other Person with which such Person or any of such Person's Affiliates or
     Associates has any agreement, arrangement or understanding (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 Section 1(d)(ii)(B) hereof) 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.

          (e) "BUSINESS DAY" shall mean any day other than a Saturday, a Sunday,
or a day on which banking institutions in New York State are authorized or
obligated by law or executive order to close.

          (f) "CLOSE OF BUSINESS" on any given date shall mean 5:00 P.M., New
York, New York time, on such date; PROVIDED, HOWEVER, that, if such date is not
a Business Day, it shall mean 5:00 P.M., New York, New York time, on the next
succeeding Business Day.

          (g) "COMMON SHARES" when used with reference to the Company shall mean
the shares of common stock, without par value, of the Company. "Common Shares"
when used with reference to any Person other than the Company shall mean the
capital stock (or equity interest) with the greatest voting power of such other
Person or, if such other Person is a Subsidi-

                                      -4-

ary of another Person, the Person or Persons which ultimately control such
first-mentioned Person.

amended.

hereof.

          (k) "FINAL EXPIRATION DATE" shall have the meaning set forth in

<PAGE>

          SECTION 3. ISSUE OF RIGHT CERTIFICATES. (a) Until the earlier of (i)
the tenth day after the Shares Acquisition Date or (ii) the tenth Business Day
(or such later date as may be determined by action of the Board of Directors of

Subsidiary of the Company, any employee benefit plan of the Company or of any
Subsidiary of the Company or any entity holding Common Shares of the Company for
or pursuant to the terms of any such plan) of a tender or exchange offer the

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 of the Company registered in the names of the
holders thereof (which certificates shall also be deemed to be Right
Certificates) and not by separate Right Certificates, and (y) the right to
receive Right Certificates will be transferable only in connection with the
transfer of Common Shares of 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 and provided with the necessary information, send) by
first-class, insured, postage-prepaid mail, to each record holder of Common
Shares of the Company 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.

                                      -7-
<PAGE>

          (b) On the Record Date, or as soon as practicable thereafter, the
Company will send a copy of a Summary of Rights to Purchase Preferred Shares, in
substantially the form of Exhibit C hereto (the "SUMMARY OF RIGHTS"), by
first-class, postage-prepaid mail, to each record holder of Common Shares as of
the Close of Business on the Record Date, at the address of such holder shown on
the records of the Company. With respect to certificates for Common Shares of
the Company 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 a copy of the Summary of Rights attached thereto.
Until the Distribution Date (or the earlier of the Redemption Date or the Final
Expiration Date), the surrender for transfer of any certificate for Common
Shares of the Company outstanding on the Record Date, with or without a copy of
the Summary of Rights attached thereto, shall also constitute the transfer of
the Rights associated with the Common Shares of the Company represented thereby.

          (c) Certificates for Common Shares which become outstanding
(including, without limitation, 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 the
following legend:

     This certificate also evidences and entitles the holder hereof to certain
     Rights as set forth in the Rights Agreement between Hercules Incorporated
     (the "Company") and ChaseMellon Shareholder Services, L.L.C. (the "Rights
     Agent"), dated as of August 4, 2000, as it may be amended from time to
     time (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. Undercertain 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. As set forth in the Rights Agreement, Rights beneficially
     owned by any Person (as defined in the Rights Agreement) who becomes an
     Acquiring Person (as defined in the Agreement) become null and void.

                                      -8-

<PAGE>

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

          SECTION 4. FORM OF RIGHT CERTIFICATES. The Right Certificates (and the
forms of election to purchase Preferred Shares and of assignment to be printed
on the reverse thereof) shall be substantially the same as 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 (but which
do not affect the duties, rights or responsibilities of the Rights Agent) 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 applicable rule or
regulation made pursuant thereto or with any applicable rule or regulation of
any stock exchange or the National Association of Securities Dealers, Inc., or
to conform to usage. Subject to the provisions of 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 number of such one one-thousandths of a Preferred Share and the
Purchase Price shall be subject to adjustment as provided herein.

                                      -9-

<PAGE>

          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, 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 individual 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 individual 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
individual was not such an officer.

          Following the Distribution Date, and receipt by the Rights Agent of
all necessary information, the Rights Agent will keep or cause to be kept, at
its office designated for such purpose (the "Designated Office"), 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.

                                      -10-
<PAGE>

          SECTION 6. TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF RIGHT
CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHT CERTIFICATES. Subject
to the provisions of Section 14 hereof, at any time after the Close of Business
on the Distribution Date, and at or prior to the Close of Business on the
earlier of the Redemption Date or the Final Expiration Date, any Right
Certificate or Right Certificates (other than Right Certificates representing
Rights that have become void pursuant to Section 11(a)(ii) hereof or that have
been exchanged pursuant to Section 24 hereof) 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 one one-thousandths
of a Preferred Share 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 Designated Office of the
Rights Agent. Thereupon the Rights Agent shall 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. The Rights
Agent shall have no duty or obligation under this Section 6 unless and until it
is reasonably satisfied that all such taxes and/or charges have been paid.

          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 satisfactory to them, and, at the Company's request, reimbursement to
the Company and the Rights Agent of all reasonable expenses inci-

                                      -11-
<PAGE>

dental 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 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) 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
properly and duly executed, to the Rights Agent at the Designated Office of the
Rights Agent, together with payment of the Purchase Price for each one
one-thousandth of a Preferred Share as to which the Rights are exercised, at or
prior to the earliest of (i) the Close of Business on August 4, 2010 (the "FINAL
EXPIRATION Date"), (ii) the time at which the Rights are redeemed as provided in
Section 23 hereof (the "REDEMPTION DATE"), or (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 purchasable pursuant to the exercise of a Right shall initially be $100,
and shall be subject to adjustment from time to time as provided in Section 11
or 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 properly and duly executed,
accompanied by payment of the Purchase Price for the shares to be purchased and
an amount equal to any applicable tax or charge required to be paid by the
holder of such Right Certificate in accordance with Section 9

                                      -12-
<PAGE>

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 certificates for the number of
Preferred Shares to be purchased and the Company hereby irrevocably authorizes
any such transfer agent to comply with all such requests, or (B) 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 of the Preferred Shares with such depositary
agent) and the Company hereby directs such 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) promptly 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, promptly
deliver such cash to or upon the order of the registered holder of such Right
Certificate.

          (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 to the registered holder of such Right Certificate or to
such holder's duly authorized assigns, subject to the provisions of Section 6
and Section 14 hereof.

          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, destroy such cancelled Right Certificates, and, in such
case, shall deliver a certificate of destruction thereof to the Company.

          SECTION 9. AVAILABILITY OF PREFERRED SHARES. The Company covenants and
agrees that it will cause to be reserved and kept available out of its
authorized and unissued Preferred Shares or any Preferred Shares held in its
treasury the number of Preferred Shares that will be sufficient to permit the
exercise in full of all outstanding Rights in accordance with Section 7 hereof.
The Company covenants and agrees that it will take all such action as may be
necessary to ensure that all Preferred Shares delivered upon exercise of Rights
shall, at the time of delivery of the certificates for such Preferred Shares
(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 taxes and charges which may be payable in respect of the
issuance or delivery of the Right Certificates or of any Preferred Shares upon
the exercise of Rights. The Company shall not, however, be required to pay any
tax or charge 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 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 upon the exercise of any Rights until

                                      -14-
<PAGE>

any such tax or charge shall have been paid (any such tax or charge 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 or charge is due.

          SECTION 10. PREFERRED SHARES RECORD DATE. Each Person in whose name
any certificate for Preferred Shares is issued upon the exercise of Rights shall
for all purposes be deemed to have become the holder of record of the Preferred
Shares 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 tax or charge) was made;
PROVIDED, HOWEVER, that, if the date of such surrender and payment is a date
upon which the Preferred Shares transfer books of the Company are closed, such
Person shall be deemed to have become the record holder of such shares on, and
such certificate shall be dated, the next succeeding Business Day on which the
Preferred Shares 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 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.

                                      -15-
<PAGE>

          (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), 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, such holder 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.

          (ii) Subject to Section 24 hereof, in the event any Person becomes an
Acquiring Person, each holder of a Right 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 (A) multiplying the then current
Purchase

                                      -16-
<PAGE>

Price by the number of one one-thousandths of a Preferred Share for which a
Right is then exercisable and dividing that product by (B) 50% of the then
current per share market price of the Common Shares of the Company (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.

          From and after the occurrence of such event, any Rights that are or
were acquired or beneficially owned by any Acquiring Person (or any Associate or
Affiliate of such Acquiring Person) shall be null and void, and any holder of
such Rights shall thereafter have no right to exercise such Rights under any
provision of this Agreement. No Right Certificate shall be issued pursuant to
Section 3 hereof that represents Rights beneficially owned by an Acquiring
Person whose Rights would be null and void pursuant to the preceding sentence or
any Associate or Affiliate thereof; no Right Certificate shall be issued at any
time upon the transfer of any Rights to an Acquiring Person whose Rights would
be null and void pursuant to the preceding sentence or any Associate or
Affiliate thereof or to any nominee of such Acquiring Person, Associate or
Affiliate; and any Right Certificate delivered to the Rights Agent for transfer
to an Acquiring Person whose Rights would be null and void pursuant to the
preceding sentence shall be cancelled.

          (iii) In the event that there shall not be sufficient Common Shares
issued but not outstanding or authorized but unissued to permit the exercise in
full of the Rights in accordance with subparagraph (ii) above, the Company shall
take all such action as may be necessary to authorize additional Common Shares
for issuance upon exercise of the Rights. In the event the Company shall, after
good faith effort, be unable to take all such action as may be necessary to
authorize such additional Common Shares, the Company shall substitute, for each
Common

                                      -17-
<PAGE>

Share that would otherwise be issuable upon exercise of a Right, a number of
Preferred Shares or fraction thereof such that the current per share market
price of one Preferred Share multiplied by such number or fraction is equal to
the current per share market price of one Common Share as of the date of
issuance of such Preferred Shares or fraction thereof.

          (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 (as defined in Section 11(d)) of the Preferred Shares 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

                                      -18-
<PAGE>

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
and holders of the Rights. 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 and shall be binding on the Rights Agent
and holders of the Rights) 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
then-current per share market price of the Preferred Shares on such record date;
PROVIDED, HOWEVER,

                                      -19-
<PAGE>

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, 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
immediately prior to but not including 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, or (B) any subdivision, combination
or reclassification of such Security and prior to the expiration of 30 Trading
Days after but not including 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 of such Security. The closing price for each day shall be the
last sale price, regular way, reported at or prior to 4:00 P.M. Eastern time or,
in case no such sale takes place on such day, the average of the bid and asked
prices, regular way, reported as of 4:00 P.M. Eastern time, 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 se-

                                      -20-
<PAGE>

curities 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
reported at or prior to 4:00 P.M. Eastern time or, if not so quoted, the average
of the high bid and low asked prices in the over-the-counter market, as reported
as of 4:00 P.M. Eastern time by 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. 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 as determined pursuant to Section 11(d)(i) hereof (appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof), multiplied by one hundred. If neither the
Common Shares 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) 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, HOW-

                                      -21-
<PAGE>

EVER, 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)
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 Section 11(a) through (c) hereof, inclusive, and
the provisions of Sections 7, 9, 10 and 13 hereof 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) hereof, upon each adjustment of the Purchase Price as a result
of the calculations made in Sections 11(b) and (c) hereof, each Right
outstanding immediately prior to the making of such

                                      -22-
<PAGE>

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
(A) 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 (B) 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 (with prompt notice thereof to the
Rights Agent) 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

                                      -23-
<PAGE>

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
in 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 (with prompt notice thereof to
the Rights Agent) until the occurrence of such event the issuing to the holder
of any Right exercised after such record date of the Preferred Shares and

                                      -24-
<PAGE>

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 in Section 11(b) hereof, hereafter made by the Company to
holders of the 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, (A)
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

                                      -25-
<PAGE>

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 (B) 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.

          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 the amount of
the adjustment and a brief statement of the facts and computations accounting
for such adjustment (including, without limitation, the record date for the
adjustment), (b) file with the Rights Agent and with each transfer agent for the
Common Shares or the Preferred Shares and the Securities and Exchange Commission
a copy of such certificate and (c) if such adjustment occurs at any time after
the Distribution Date, 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 shall have no duty with respect to and shall not be deemed to have
knowledge of any such adjustment unless and until it shall have received such
certificate.

          SECTION 13. CONSOLIDATION, MERGER OR SALE OR TRANSFER OF ASSETS OR
EARNING POWER. In the event, directly or indirectly, at any time after a Person
has become an Acquiring Person, (a) the Company shall consolidate with, or merge
with and into, any other Person, (b) 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

                                      -26-
<PAGE>

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 (c) the Company shall sell or otherwise transfer
(or one or more of its Subsidiaries shall sell or otherwise transfer), in one or
more transactions, assets or earning power aggregating 50% or more of the assets
or earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person 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 Common Shares of such other Person (including the Company as
successor thereto or as the surviving corporation) 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 and
dividing that product by (B) 50% of the then current per share market price of
the Common Shares of such other Person (determined pursuant to Section 11(d)
hereof) on the date of consummation of such consolidation, merger, sale or
transfer; (ii) the issuer of such Common Shares shall thereafter be liable for,
and shall assume, by virtue of such consolidation, merger, sale or transfer, all
the obligations and duties of the Company pursuant to this Agreement; (iii) the
term "Company" shall thereafter be deemed to refer to such issuer; and (iv) such
issuer 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

                                      -27-
<PAGE>

the Common Shares of the Company thereafter deliverable upon the exercise of the
Rights. The Company shall not consummate any such consolidation, merger, sale or
transfer unless, prior thereto, the Company and such issuer shall have executed
and delivered to the Rights Agent a supplemental agreement so providing. The
Company shall not enter into any transaction of the kind referred to in this
Section 13 if at the time of such transaction there are any rights, warrants,
instruments or securities outstanding or any agreements or arrangements which,
as a result of the consummation of such transaction, would eliminate or
substantially diminish the benefits intended to be afforded by the Rights. The
provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers.

          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 shall 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

                                      -28-
<PAGE>

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 shall 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 Preferred Share. For the purposes of
this Section 14(b), the current market value of a Preferred Share shall be the

                                      -29-
<PAGE>

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) The holder of a Right, by the acceptance of the Right, expressly
waives such holder's right to receive any fractional Rights or any fractional
shares upon exercise of a Right (except as provided above).

          The Rights Agent shall have no duty or obligation with respect to this
Section 14 and Section 24(d) unless and until it has received specific
instructions (and sufficient cash, if required) from the Company with respect to
its duties and obligations under such Sections.

          SECTION 15. RIGHTS OF ACTION. All rights of action in respect of this
Agreement, excepting the rights of action expressly 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 Certificate (or,
prior to the Distribution Date, of the Common Shares), without the consent of
the Rights Agent or of the holder of any other Right Certificate (or, prior to
the Distribution Date, of the Common Shares), may, in such holder's own behalf
and for such holder's own benefit, enforce, and may institute and maintain any
suit, action or proceeding against the Company to enforce, or otherwise act in
respect of, such holder's right to exercise the Rights evidenced by such Right
Certificate in the manner provided in such Right Certificate and in this
Agreement. Without limiting the foregoing or any remedies available to the
holders of Rights, it is specifically acknowledged that the holders of Rights
would not have an adequate remedy at law for any breach of this Agreement, and
will be entitled to specific performance of the obligations under,

                                      -30-
<PAGE>

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 Designated Office of the Rights Agent, duly endorsed or accompanied by a
proper instrument of transfer; and

          (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 Certificate 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.

          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 purpose 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 con-

                                      -31-
<PAGE>

tained 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 incurred in the
administration, preparation, delivery, amendment 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, damage, judgement, fine, penalty, claim, demand, settlement,
cost or expense incurred without gross negligence, bad faith or willful
misconduct (each as finally determined by a court of competent jurisdiction) on
the part of the Rights Agent, for any action taken, suffered or omitted by the
Rights Agent in connection with the acceptance, amendment and administration of
this Agreement, including without limitation the costs and expenses of defending
against any claim of liability arising therefrom directly or indirectly in the
premises. The indemnity provided herein shall survive the termination of this
Agreement and the termination and expiration of the Rights.

          The Rights Agent shall be authorized and protected and shall incur no
liability for, or in respect of any action taken, suffered or omitted by it in
connection with, its administration

                                      -32-
<PAGE>

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 Person into which the Rights Agent or any successor Rights Agent may be
merged or with which it may be consolidated, or any Person resulting from any
merger or consolidation to which the Rights Agent or any successor Rights Agent
shall be a party, or any Person succeeding to the shareholder services business
of the Rights Agent or any successor Rights Agent, shall be the successor to the
Rights Agent under this Agreement without the execution or filing of any paper
or any further act on the part of any of the parties hereto; PROVIDED that such
Person 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.

                                      -33-
<PAGE>

          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 expressly 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 (who may be legal
counsel for the Company), and the advice or opinion of such counsel shall be
full and complete authorization and protection to the Rights Agent as to any
action taken, suffered or omitted by it in accordance with such advice or
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, suffering or omitting any
action hereunder, such fact or matter (unless other evidence in respect thereof
be herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board, the
Chief Executive Officer, 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

                                      -34-
<PAGE>

authorization and protection to the Rights Agent for any action taken or
suffered or omitted by it under the provisions of this Agreement in reliance
upon such certificate.

          (c) The Rights Agent shall be liable hereunder to the Company and any
other Person only for its own gross negligence, bad faith or willful misconduct
(each as finally determined by a court of competent jurisdiction). Anything to
the contrary notwithstanding, in no event shall the Rights Agent be liable for
special, punitive, indirect, consequential or incidental loss or damage of any
kind whatsoever (including but not limited to lost profits), even if the Rights
Agent has been advised of the likelihood of such loss or damage.

          (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 countersignature thereof) or be required to verify the
same, but all such statements and recitals are and shall be deemed to have been
made by the Company only.

          (e) The Rights Agent shall not be under any liability or
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 or liable 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 or liable for any change in
the exercisability of the Rights (including the Rights becoming null and void
pursuant to Section 11(a)(ii) 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 hereof, 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

                                      -35-
<PAGE>

Certificates after actual notice that such change or adjustment is required);
nor shall it by any act hereunder be deemed to make any representation or
warranty as to the authorization or reservation of any Preferred Shares to be
issued pursuant to this Agreement or any Right Certificate or as to whether any
Preferred Shares will, when issued, be validly authorized and issued, fully paid
and nonassessable.

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

          (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
one of the Chairman of the Board, the Chief Executive Officer, the President,
any Vice President, the 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 or omitted by it in
accordance with instructions of any such officer or for any delay in acting
while waiting for those instructions.

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

                                      -36-
<PAGE>

          (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 that reasonable care was exercised in the
selection and continued employment thereof.

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

          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 (which holder
shall, with such notice, submit such holder's

                                      -37-
<PAGE>

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 (i) a Person organized and doing
business and in good standing under the laws of the United States, the State of
New York or of any other state of the United States, so long as such Person is
authorized under such laws to exercise all of the duties of the Rights Agent
under this Agreement and is subject to supervision or examination by federal or
state authority and which has at the time of its appointment as Rights Agent a
combined capital and surplus of at least $50 million or (ii) an Affiliate of
such Person. 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 the Board of Directors of the Company to reflect any
adjustment or change in the Purchase Price and the

                                      -38-
<PAGE>

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 $.001 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 of the Company may be
made effective at such time, on such basis and with such conditions as the Board
of Directors of the Company, in its sole discretion, may establish.

          (b) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights 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 of the
Company ordering the redemption of the Rights, 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. Neither the Company nor

                                      -39-
<PAGE>

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 or in Section 24 hereof, and other than 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 any Person becomes an Acquiring Person,
exchange all or part of the then outstanding and exercisable Rights (which shall
not include Rights that have become null and void pursuant to the provisions of
Section 11(a)(ii) hereof) for Common Shares at an exchange ratio of one Common
Share per Right, appropriately adjusted to reflect any adjustment in the number
of Rights pursuant to Section 11(i) (such exchange ratio being hereinafter
referred to as the "EXCHANGE RATIO"). Notwithstanding the foregoing, the Board
of Directors of the Company shall not be empowered to effect such exchange at
any time after any Person (other than the Company, any Subsidiary of the
Company, any employee benefit plan of the Company or any such Subsidiary, or any
entity holding Common 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 the
holders 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.

                                      -40-
<PAGE>

The Company promptly shall mail a notice of any such exchange to the Rights
Agent and 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 null and void pursuant to the provisions of
Section 11(a)(ii) hereof) held by each holder of Rights.

          (c) In the event that there shall not be sufficient Common Shares
issued but not outstanding or authorized but unissued to permit any exchange of
Rights as contemplated in accordance with this Section 24, the Company shall
take all such action as may be necessary to authorize additional Common Shares
for issuance upon exchange of the Rights. In the event the Company shall, after
good faith effort, be unable to take all such action as may be necessary to
authorize such additional Common Shares, the Company shall substitute, for each
Common Share that would otherwise be issuable upon exchange of a Right, a number
of Preferred Shares or fraction thereof such that the current per share market
price of one Preferred Share multiplied by such number or fraction is equal to
the current per share market price of one Common Share as of the date of
issuance of such Preferred Shares or fraction thereof.

          (d) The Company shall not be required to issue fractions of Common
Shares or to distribute certificates which evidence fractional Common Shares. In
lieu of such fractional Common Shares, 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

                                      -41-
<PAGE>

equal to the same fraction of the current market value of a whole Common Share.
For the purposes of this paragraph (d), 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,
at any time after the Distribution Date, propose (i) to pay any dividend payable
in stock of any class to the holders of the Preferred Shares or to make any
other distribution to the holders of the Preferred Shares (other than a regular
quarterly cash dividend), (ii) to offer to the holders of the 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 the 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 the Rights Agent and 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,
consolidation, merger,

                                      -42-
<PAGE>

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 the event 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

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

Agreement by or for the benefit of the Company or the Rights Agent shall bind

shall be construed to give to any Person 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 the registered holders of
the Right Certificates (and, prior to the Distribution Date, the Common Shares).

          SECTION 30. SEVERABILITY. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or

                              HERCULES INCORPORATED

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

                             -----------------------

          Hercules Incorporated, a corporation organized and existing under the
General Corporation Law of the State of Delaware (hereinafter called the
"Corporation"), hereby certifies that the following resolution was adopted by
the Board of Directors of the Corporation as required by Section 151 of the
General Corporation Law at a meeting duly called and held on August 4, 2000:

          RESOLVED, that pursuant to the authority granted to and vested in the
Board of Directors of this Corporation (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Certificate
of Incorporation, the Board of Directors hereby creates a series of Preferred
Stock, without par value, of the Corporation (the "Preferred Stock"), and hereby
states the designation and number of shares, and fixes the relative rights,
preferences, and limitations thereof as follows:

          Series A Junior Participating Preferred Stock:

          SECTION 1. DESIGNATION AND AMOUNT. The shares of such series shall be
designated as "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting the Series A Preferred
Stock shall be 125,000. Such number of shares may be increased or decreased by
resolution of the Board of Directors; PROVIDED, that no decrease shall reduce
the number of shares of Series A Preferred Stock to a number less than the
number of shares then outstanding plus the number of shares reserved for
issuance upon the exercise of outstanding options, rights or warrants or upon
the conversion of any outstanding securities issued by the Corporation
convertible into Series A Preferred Stock.

          SECTION 2. DIVIDENDS AND DISTRIBUTIONS.

          (A) Subject to the rights of the holders of any shares of any series
     of Preferred Stock (or any similar stock) ranking prior and superior to the
     Series A Preferred Stock

                                       A-1
<PAGE>

     with respect to dividends, the holders of shares of Series A Preferred
     Stock, in preference to the holders of Common Stock, without par value (the
     "Common Stock"), of the Corporation, and of any other junior stock, shall
     be entitled to receive, when, as and if declared by the Board of Directors
     out of funds legally available for the purpose, quarterly dividends payable
     in cash on the first day of March, June, September and December in each
     year (each such date being referred to herein as a "Quarterly Dividend
     Payment Date"), commencing on the first Quarterly Dividend Payment Date
     after the first issuance of a share or fraction of a share of Series A
     Preferred Stock, in an amount per share (rounded to the nearest cent) equal
     to the greater of (a) $1 or (b) subject to the provision for adjustment
     hereinafter set forth, 1000 times the aggregate per share amount of all
     cash dividends, and 1000 times the aggregate per share amount (payable in
     kind) of all non-cash dividends or other distributions, other than a
     dividend payable in shares of Common Stock or a subdivision of the
     outstanding shares of Common Stock (by reclassification or otherwise),
     declared on the Common Stock since the immediately preceding Quarterly
     Dividend Payment Date or, with respect to the first Quarterly Dividend
     Payment Date, since the first issuance of any share or fraction of a share
     of Series A Preferred Stock. In the event the Corporation shall at any time
     declare or pay any dividend on the Common Stock payable in shares of Common
     Stock, or effect a subdivision or combination or consolidation of the
     outstanding shares of Common Stock (by reclassification or otherwise than
     by payment of a dividend in shares of Common Stock) into a greater or
     lesser number of shares of Common Stock, then in each such case the amount
     to which holders of shares of Series A Preferred Stock were entitled
     immediately prior to such event under clause (b) of the preceding sentence
     shall be adjusted by multiplying such amount by a fraction, the numerator
     of which is the number of shares of Common Stock outstanding immediately
     after such event and the denominator of which is the number of shares of
     Common Stock that were outstanding immediately prior to such event.

          (B) The Corporation shall declare a dividend or distribution on the
     Series A Preferred Stock as provided in paragraph (A) of this Section
     immediately after it declares a dividend or distribution on the Common
     Stock (other than a dividend payable in shares of Common Stock); provided
     that, in the event no dividend or distribution shall have been declared on
     the Common Stock during the period between any Quarterly Dividend Payment
     Date and the next subsequent Quarterly Dividend Payment Date, a dividend of
     $1 per share on the Series A Preferred Stock shall nevertheless be payable
     on such subsequent Quarterly Dividend Payment Date.

          (C) Dividends shall begin to accrue and be cumulative on outstanding
     shares of Series A Preferred Stock from the Quarterly Dividend Payment Date
     next preceding the date of issue of such shares, unless the date of issue
     of such shares is prior to the record date for the first Quarterly Dividend
     Payment Date, in which case dividends on such shares shall begin to accrue
     from the date of issue of such shares, or unless the date of issue is a
     Quarterly Dividend Payment Date or is a date after the record date for the
     determination of holders of shares of Series A Preferred Stock entitled to
     receive a quarterly dividend and before such Quarterly Dividend Payment
     Date, in either of which events such dividends shall begin to accrue and be
     cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid
     dividends shall not bear interest. Dividends paid on the shares of Series A
     Preferred Stock in an amount less than the total amount of such

                                      A-2
<PAGE>

     dividends at the time accrued and payable on such shares shall be allocated
     pro rata on a share-by-share basis among all such shares at the time
     outstanding. The Board of Directors may fix a record date for the
     determination of holders of shares of Series A Preferred Stock entitled to
     receive payment of a dividend or distribution declared thereon, which
     record date shall be not more than 60 days prior to the date fixed for the
     payment thereof.

          SECTION 3. VOTING RIGHTS. The holders of shares of Series A Preferred
Stock shall have the following voting rights:

          (A) Subject to the provision for adjustment hereinafter set forth,
     each share of Series A Preferred Stock shall entitle the holder thereof to
     1000 votes on all matters submitted to a vote of the stockholders of the
     Corporation. In the event the Corporation shall at any time declare or pay
     any dividend on the Common Stock payable in shares of Common Stock, or
     effect a subdivision or combination or consolidation of the outstanding
     shares of Common Stock (by reclassification or otherwise than by payment of
     a dividend in shares of Common Stock) into a greater or lesser number of
     shares of Common Stock, then in each such case the number of votes per
     share to which holders of shares of Series A Preferred Stock were entitled
     immediately prior to such event shall be adjusted by multiplying such
     number by a fraction, the numerator of which is the number of shares of
     Common Stock outstanding immediately after such event and the denominator
     of which is the number of shares of Common Stock that were outstanding
     immediately prior to such event.

          (B) Except as otherwise provided herein, in any other Certificate of
     Designations creating a series of Preferred Stock or any similar stock, or
     by law, the holders of shares of Series A 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 stockholders of the Corporation.

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

          SECTION 4. CERTAIN RESTRICTIONS.

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

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

               (ii) declare or pay dividends, or make any other distributions,
          on any shares of stock ranking on a parity (either as to dividends or
          upon liquidation, dis-

                                      A-3
<PAGE>

          solution or winding up) with the Series A Preferred Stock, except
          dividends paid ratably on the Series A Preferred Stock and all such
          parity stock on which dividends are payable or in arrears in
          proportion to the total amounts to which the holders of all such
          shares are then entitled;

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

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

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

          SECTION 5. REACQUIRED SHARES. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
subject to the conditions and restrictions on issuance set forth herein, in the
Certificate of Incorporation, or in any other Certificate of Designations
creating a series of Preferred Stock or any similar stock or as otherwise
required by law.

          SECTION 6. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any
liquidation, dissolution or winding up of the Corporation, no distribution shall
be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
Preferred Stock shall have received $1000 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series A
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 1000
times the aggregate amount to be distributed per share to holders of shares of
Common Stock, or (2) to the holders of shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the
Series A Preferred Stock, except distributions made ratably on the Series A
Preferred Stock and all such parity stock in proportion to the total

                                      A-4

<PAGE>

amounts to which the holders of all such shares are entitled upon such
liquidation, dissolution or winding up. In the event the Corporation shall at
any time declare or pay any dividend on the Common Stock payable in shares of
Common Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the aggregate amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under the proviso in clause (1) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

          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 each share of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 1000 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 declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

          SECTION 8. NO REDEMPTION. The shares of Series A Preferred Stock shall
not be redeemable.

          SECTION 9. RANK. The Series A Preferred Stock shall rank, with respect
to the payment of dividends and the distribution of assets, junior to all series
of any other class of the Corporation's Preferred Stock.

          SECTION 10. AMENDMENT. The 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 A Preferred Stock
so as to affect them adversely without the affirmative vote of the holders of at
least two-thirds of the outstanding shares of Series A Preferred Stock, voting
together as a single class.

Share (the "Purchase Price"), upon presentation and surrender of this Right
Certificate with the Form of Election to Purchase duly executed. The number of
Rights evidenced by this Right Certificate (and the number of one
one-thousandths of a Preferred Share which may be purchased upon exercise
hereof) set forth above, and the Purchase Price set forth above, are the number
and Purchase Price as of August ___, 2000, based on the Preferred Shares as

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 Agreement, which terms, provisions and conditions are hereby

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

INTRODUCTION

          On August 4, 2000, the Board of Directors of our Company, Hercules
Incorporated, a Delaware corporation, declared a dividend of one preferred share
purchase right (a "Right") for each outstanding share of common stock, without
par value. The dividend is payable on August 14, 2000 to the stockholders of
record on August 14, 2000.

          Our Board has adopted this Rights Agreement to protect stockholders
from coercive or otherwise unfair takeover tactics. In general terms, it works
by imposing a significant penalty upon any person or group which acquires 10% or
more of our outstanding common stock without the approval of our Board. The
Rights Agreement should not interfere with any merger or other business
combination approved by our Board.

          For those interested in the specific terms of the Rights Agreement as
made between our Company and ChaseMellon Shareholder Services, L.L.C., as the
Rights Agent, on August 4, 2000, we provide the following summary description.
Please note, however, that this description is only a summary, and is not
complete, and should be read together with the entire Rights Agreement, which
has been filed with the Securities and Exchange Commission as an exhibit to a
Registration Statement on Form 8-A dated August ___, 2000. A copy of the
agreement is available free of charge from our Company.

THE RIGHTS. Our Board authorized the issuance of a Right with respect to each
outstanding share of common stock on August 14, 2000. The Rights will initially
trade with, and will be inseparable from, the common stock. The Rights are
evidenced only by certificates that represent shares of common stock. New Rights
will accompany any new shares of common stock we issue after August 14, 2000
until the Distribution Date described below.

EXERCISE PRICE. Each Right will allow its holder to purchase from our Company
one one-thousandth of a share of Series A Junior Participating Preferred Stock
("Preferred Share") for $100, once the Rights become exercisable. This portion
of a Preferred Share will give the stockholder approximately the same dividend,
voting, and liquidation rights as would one share of common stock. Prior to
exercise, the Right does not give its holder any dividend, voting, or
liquidation rights.

EXERCISABILITY. The Rights will not be exercisable until

o  10 days after the public announcement that a person or group has become an
   "Acquiring Person" by obtaining beneficial ownership of 10% or more of our
   outstanding common stock, or, if earlier,

o  10 business days (or a later date determined by our Board before any person
   or group becomes an Acquiring Person) after a person or group begins a tender
   or exchange offer which, if completed, would result in that person or group
   becoming an Acquiring Person.

                                      C-1
<PAGE>

          We refer to the date when the Rights become exercisable as the
"Distribution Date." Until that date, the common stock certificates will also
evidence the Rights, and any transfer of shares of common stock will constitute
a transfer of Rights. After that date, the Rights will separate from the common
stock and be evidenced by book-entry credits or by Rights certificates that we
will mail to all eligible holders of common stock. Any Rights held by an
Acquiring Person are void and may not be exercised.

CONSEQUENCES OF A PERSON OR GROUP BECOMING AN ACQUIRING PERSON.

o  FLIP IN. If a person or group becomes an Acquiring Person, all holders of
   Rights except the Acquiring Person may, for $100, purchase shares of our
   common stock with a market value of $200, based on the market price of the
   common stock prior to such acquisition.

o  FLIP OVER. If our Company is later acquired in a merger or similar
   transaction after the Rights Distribution Date, all holders of Rights except
   the Acquiring Person may, for $100, purchase shares of the acquiring
   corporation with a market value of $200 based on the market price of the
   acquiring corporation's stock, prior to such merger.

PREFERRED SHARE PROVISIONS.

Each one one-thousandth of a Preferred Share, if issued:

o  will not be redeemable.

o  will entitle holders to quarterly dividend payments of $.001 per share, or an
   amount equal to the dividend paid on one share of common stock, whichever is
   greater.

o  will entitle holders upon liquidation either to receive $1 per share or an
   amount equal to the payment made on one share of common stock, whichever is
   greater.

o  will have the same voting power as one share of common stock.

o  if shares of our common stock are exchanged via merger, consolidation, or a
   similar transaction, will entitle holders to a per share payment equal to the
   payment made on one share of common stock.

The value of one one-thousandth interest in a Preferred Share should approximate
the value of one share of common stock.

EXPIRATION.  The Rights will expire on August 4, 2010.

REDEMPTION. Our Board may redeem the Rights for $.001 per Right at any time
before any person or group becomes an Acquiring Person. If our Board redeems any
Rights, it must redeem all of the Rights. Once the Rights are redeemed, the only
right of the holders of Rights will be to receive the redemption price of $.001
per Right. The redemption price will be adjusted if we have a stock split or
stock dividends of our common stock.

                                      C-2
<PAGE>

EXCHANGE. After a person or group becomes an Acquiring Person, but before an
Acquiring Person owns 50% or more of our outstanding common stock, our Board may
extinguish the Rights by exchanging one share of common stock or an equivalent
security for each Right, other than Rights held by the Acquiring Person.

ANTI-DILUTION PROVISIONS. Our Board may adjust the purchase price of the
Preferred Shares, the number of Preferred Shares issuable and the number of
outstanding Rights to prevent dilution that may occur from a stock dividend, a
stock split, a reclassification of the Preferred Shares or common stock. No
adjustments to the Exercise Price of less than 1% will be made.

AMENDMENTS. The terms of the Rights Agreement may be amended by our Board
without the consent of the holders of the Rights. After a person or group
becomes an Acquiring Person, our Board may not amend the agreement in a way that
adversely affects holders of the Rights.

                                      C-3REPLACEMENT REVOLVING NOTE

$25,000,000                                            Dated as of June 28, 2000
                                                             Due:  June 28, 2001

         On  or  before  June  28,  2001,  CDW  COMPUTER   CENTERS,   INC.  (the
"Undersigned"), for value received, promises to pay to the order of LASALLE BANK
NATIONAL  ASSOCIATION,  formerly  known as  LaSalle  National  Bank,  a national
banking  association  (hereinafter,  together  with any holder  thereof,  called
"Bank"),  whose address is 135 S. LaSalle Street,  Chicago,  Illinois 60603, the
principal  sum of Twenty Five  Million and 00/100  Dollars  ($25,000,000)  or if
less, the aggregate unpaid principal amount of all loans made by the Bank to the
Undersigned  hereunder (this "Note").  The unpaid  principal amount hereof shall
bear interest at the Undersigned's option of the following:

         (i) a  fixed  rate  equal  to the  greater  of  (A)  the  "Prime  Rate"
(hereinafter  defined) minus two and one-half  percent (- 2 1/2%) per annum,  or
(B) the "Federal Funds Rate" (hereinafter  defined) plus one-half of one percent
(+ 1/2%) per annum,  for borrowings not to exceed thirty (30) days, such rate to
be fixed  at the  beginning  of the term of such  borrowing  (the  "Fixed  Prime
Rate"); or

         (ii) a floating  rate equal to the  greater of (A) the Prime Rate minus
two and one-half percent (-2 1/2%) per annum, or (B) the Federal Funds Rate plus
one-half of one percent (+ 1/2%) per annum,  for  borrowings in excess of thirty
(30) days (the  "Floating  Prime Rate");  the Floating  Prime Rate and the Fixed
Prime Rate are referred to herein collectively as the "Prime Rate"); or

         (iii)    "Adjusted LIBOR" (hereinafter defined).

1. For purposes hereof the following terms shall have the following definitions:

"Prime  Rate" shall mean the rate in effect from time to time as set by the Bank
and called its Prime Rate.  The effective  date of any change in said Prime Rate
shall for purposes  hereof be the date the rate is changed by the Bank. The Bank
shall not be obligated to give notice of any change in the Prime Rate.

"Federal Funds Rate" shall mean, for any day, the daily effective  Federal Funds
rate  for such day as  published  in the  Federal  Reserve  Statistical  Release
H.15("H.15")  (or, if such Release is not  published,  the successor  thereto or
closest approximation thereto, as determined by the Bank) for such day; provided
that,  the Federal  Funds Rate for any day on which the Federal  Reserve Bank of
New York,  (the "New York Fed") is not open for  business  shall be the  Federal
Funds  Rate for the next  preceding  day on which  the New York Fed was open for
business;  and provided,  further,  that if the Bank determines,  in good faith,
that it is unable to determine the Federal Funds Rate on the basis of H.15, then
the Bank shall determine the Federal Funds Rate based on the quotations of three
(3) dealers in Federal  Funds in New York City,  as  reasonably  selected by the
Bank, and the Bank's  determination of such rate shall be binding and conclusive
absent manifest error.

"Adjusted  LIBOR"  means a rate of  interest  equal to  one-half  of one percent
(1/2%)  per  annum in excess of the per annum  rate of  interest  at which  U.S.
dollar  deposits in an amount  comparable  to the amount of the relevant  "LIBOR
Loan"  (hereinafter  defined) and for a period  equal to the relevant  "Interest
Period" (hereinafter defined) are offered generally to the Bank (rounded upward,
if necessary,  to the nearest 1/16 of 1.00%) in the London Interbank  Eurodollar
market  at  11:00  a.m.  (London  time)  two  (2)  banking  days  prior  to  the
commencement  of each  Interest  Period,  such  rate to  remain  fixed  for such
Interest Period.

"Interest  Period"  shall mean  successive  one, two or  three-month  periods as
selected  from time to time by the  Undersigned  by notice given to the Bank not
less than  three (3)  business  days  prior to the first day of each  respective
Interest  Period;  provided that:  (i) each such one, two or three-month  period
occurring  after such initial period shall commence on the day on which the next
preceding period expires;  (ii) the final Interest Period shall be such that its
expiration  occurs on or before the stated  maturity date of the Note; and (iii)
if for any reason the Undersigned shall fail to select timely a period,  then it
shall be deemed to have  selected  a LIBOR  Loan  with a one(1)  month  Interest
Period; provided that, at any time any Interest Period expires less than one (1)
month before the maturity of the Note,  then, for the period  commencing on such
expiration date and ending on the maturity date such LIBOR Loan shall convert to
a loan bearing interest at the Floating Prime Rate.

         2. Interest on that portion of the outstanding  principal amount hereof
bearing interest at the Prime Rate shall be payable from the date hereof on such
aggregate unpaid  principal amount on the last day of each month,  commencing on
June 30, 2000, and at maturity  hereof.  Interest on LIBOR  borrowings  shall be
payable at the end of each respective  Interest Period.  Interest after maturity
(whether by reason of  acceleration  or  otherwise)  shall be paid on the unpaid
balance at the rate of the  Floating  Prime Rate plus two percent (2%) per annum
(the  "Default  Rate").  Interest  shall  be  computed  on the  basis  of a year
consisting  of 360 days and shall be paid for the actual number of days elapsed,
unless otherwise specified herein.

         3. Each LIBOR  borrowing  hereunder  (each,  a "LIBOR Loan") must equal
$100,000 or an integral multiple  thereof.  Interest on each LIBOR Loan shall be
payable on the last banking day of each  Interest  Period with respect  thereto,
commencing  on the first such date to occur after the date hereof,  at maturity,
after  maturity on demand,  and on the date of any payment  hereon on the amount
paid. The Undersigned  hereby further  promises to pay to the order of the Bank,
on demand,  interest  on the  unpaid  principal  amount  hereof  after  maturity
(whether by acceleration or otherwise) at the Default Rate.

         4. Provisions  applicable to LIBOR Loans: (a) The Bank's  determination
of Adjusted LIBOR as provided above shall be conclusive,  absent manifest error.
Furthermore, if the Bank determines, in good faith (which determination shall be
conclusive,  absent manifest  error),  prior to the commencement of any Interest
Period that (a) U.S.  dollar  deposits of  sufficient  amount and  maturity  for
funding  any LIBOR Loan are not  available  to the Bank in the London  Interbank
Eurodollar  market  in the  ordinary  course  of  business,  or (b) by reason of
circumstances  affecting the London Interbank  Eurodollar  market,  adequate and
fair means do not exist for  ascertaining  the rate of interest to be applicable
to the relevant LIBOR Loan, the Bank shall promptly  notify the  Undersigned and
such LIBOR Loan shall automatically  convert on the last day of its then-current
Interest Period to a loan bearing interest at the Floating Prime Rate.

(b) If,  after  the date  hereof,  the  introduction  of,  or any  change in any
applicable law, treaty,  rule,  regulation or guideline or in the interpretation
or administration  thereof by any governmental  authority or any central bank or
other fiscal,  monetary or other authority having  jurisdiction over the Bank or
its lending office (a "Regulatory Change"),  shall, in the opinion of counsel to
the Bank,  makes it  unlawful  for the Bank to make or  maintain  any LIBOR Loan
evidenced  hereby,  then the Bank shall promptly notify the Undersigned and such
LIBOR  Loan  shall  automatically  convert  on the last day of its  then-current
Interest Period to a loan bearing interest at the Floating Prime Rate.

(c) If, for any reason, any LIBOR Loan is paid prior to the last business day of
its then-current  Interest Period,  the Undersigned agrees to indemnify the Bank
against any loss (including any loss on redeployment of the funds repaid),  cost
or expense incurred by the Bank as a result of such prepayment.

(d) If any Regulatory  Change (whether or not having the force of law) shall (a)
impose,  modify or deem applicable any assessment,  reserve,  special deposit or
similar requirement against assets held by, or deposits in or for the account of
or loans by, or any other  acquisition of funds or  disbursements  by, the Bank;
(b) subject the Bank or any LIBOR Loan to any tax,  duty,  charge,  stamp tax or
fee or change the basis of  taxation of  payments  to the Bank of  principal  or
interest due from the Undersigned to the Bank hereunder  (other than a change in
taxation of the  overall net income of the Bank);  or (c) impose on the Bank any
other condition regarding such LIBOR Loan or the Bank's funding thereof, and the
Bank shall determine (which  determination shall be conclusive,  absent manifest
error) that the result of the  foregoing  is to increase the cost to the Bank of
making or  maintaining  such LIBOR Loan or to reduce the amount of  principal or
interest  received by the Bank hereunder,  then the Undersigned shall pay to the
Bank, on demand and presentation of satisfactory  documentation  therefor,  such
additional  amounts  as the  Bank  shall,  from  time  to  time,  determine  are
sufficient to  compensate  and  indemnify  the Bank for such  increased  cost or
reduced amount.

         5. The Undersigned  hereby authorizes the Bank to charge any account of
the  Undersigned  for all sums due hereunder.  Principal  payments  submitted in
funds not  available  until  collected  shall  continue to bear  interest  until
collected. If payment hereunder becomes due and payable on a Saturday, Sunday or
legal holiday under the laws of the United States or the State of Illinois,  the
due date  thereof  shall be extended to the next  succeeding  business  day, and
interest shall be payable thereon at the rate specified during such extension.

         6. This Note  evidences  a  revolving  line of credit  under  which the
Undersigned is indebted to the Bank and evidences the aggregate unpaid principal
amount of all advances made or to be made by the Bank to the  Undersigned  under
the Note. All advances and repayments hereunder shall be evidenced by entries on
the books and  records of the Bank which  shall be  presumptive  evidence of the
principal  amount and interest  owing and unpaid on this Note, or any renewal or
extension  hereof.  The  failure  to so record  any such  amount or any error so
recording  any such amount shall not,  however,  limit or  otherwise  affect the
obligations of the Undersigned hereunder or under any not to repay the principal
amount of the liabilities together with all interest accruing thereon. This Note
may be used for direct  advances  or letters  of credit.  Each  letter of credit
requested by the Undersigned shall be subject to the terms and conditions of the
Bank's standard letter of credit application,  which application is incorporated
herein by this reference.  The amount  available to the  Undersigned  under this
Note  shall be reduced by the face  amount of all  letters of credit  issued and
outstanding  hereunder.  All letters of credit  issued  hereunder  shall have an
expiry date no later than June 28, 2001. The Undersigned and the Bank agree that
each draw under any letter of credit shall constitute, and shall be repaid by, a
direct  advance under this Note on the date of such draw.  Each letter of credit
requested by the  Undersigned  hereunder  shall be issued by the Bank only after
the Bank has  received  a fully  executed  letter of credit  application  on the
Bank's  standard form and the Bank's  customary  fees for issuance of letters of
credit.

         7.  Advances  under this Note may be made by the Bank upon the  written
request of any two (2) authorized officers of the Undersigned whose authority to
so act has not been revoked by the Undersigned in writing  theretofore  received
by the Bank at its main office. Any such advances shall be conclusively presumed
to have  been made by the Bank to or for the  benefit  of the  Undersigned.  The
Undersigned  does  hereby  irrevocably  confirm,  ratify  and  approve  all such
advances  by the Bank and  does  hereby  indemnify  the  Bank  against  loss and
reasonable expenses (including court costs, attorneys' and paralegals' fees) and
shall hold the Bank harmless with respect thereto.

         8. The  Undersigned  shall be in default  hereunder  if: (a) any amount
payable  on this  and  any  and all  other  liabilities  or  obligations  of the
Undersigned to the Bank,  howsoever created,  arising or evidenced,  whether now
existing or hereafter arising, whether now due or to become due, whether direct,
indirect,  absolute,  contingent,  joint, several or joint and several (all such
liabilities and obligations, including this Note, are hereinafter referred to as
the "Obligations") or on the obligations of any obligor  hereunder,  it not paid
within five (5) days of when due; or (b) the Undersigned shall otherwise fail to
perform any of the  promises to be  performed  by the  Undersigned  hereunder or
under any other security agreement or other agreement with the Bank and the same
is not cured within  thirty (30) days of notice  thereof by the Bank; or (c) the
Undersigned,  or any other party liable with respect to the Obligations,  or any
guarantor  or  accommodation  endorser  or third party  pledgor,  shall make any
assignment  for the  benefit  of  creditors,  or there  shall be  commenced  any
bankruptcy, receivership, insolvency, reorganization, dissolution or liquidation
proceedings  by or  against,  or the entry of any  judgment,  levy,  attachment,
garnishment or other process,  or the filing of any lien against the Undersigned
or any guarantor, or any other party liable with respect to the Obligations,  or
accommodation  endorser or third party pledgor for any of the Obligations  which
has a material  adverse effect on such party;  or (d) the  determination  by the
Bank that a material  adverse change has occurred in the financial  condition of
the  Undersigned  from the  condition  set  forth in the most  recent  financial
statement  of the  Undersigned  furnished  to the  Bank,  or from the  financial
condition of the Undersigned  most recently  disclosed to the Bank in any manner
and the same is not cured within thirty (30) days of notice thereof by the Bank;
or (e) any oral or written warranty, representation, certificate or statement of
the Undersigned to the Bank is untrue in any material respect; or (f) failure of
the Undersigned, within thirty (30) days after a request by the Bank, to furnish
financial  information or to permit  inspection by the Bank of the Undersigned's
books and records;  or (g) the  occurrence  of any material  adverse event which
causes a change in the financial  condition of the  Undersigned,  or which would
have a material  adverse effect on the business of the  Undersigned and the same
is not cured  within  thirty (30) days notice  thereof by the Bank;;  or (h) the
Undersigned  fails  to have,  at the end of each of its  fiscal  quarters  (1) a
Tangible Net Worth of at least  $100,000,000,  or (2) a ratio of  Liabilities to
Tangible Net Worth of no greater than 2.0:1.0 and a default of either (1) or (2)
shall not be cured by the Undersigned within thirty (30) days.

         9. For  purposes  hereof,  "Tangible  Net Worth"  shall mean the sum of
shareholders' equity plus debt subordinated to the Undersigned's  liabilities to
the Bank, minus intangibles,  including, but not limited to, goodwill,  customer
lists,  prepaid  items,  deferred  charges,  debts  owed by  officers  and other
affiliates and such "Other  Assets" as set forth on the financial  statements of
the  Undersigned.  "Liabilities"  shall mean all  liabilities of the Undersigned
that would be shown on a balance sheet of the Undersigned prepared in accordance
with generally accepted accounting principles consistently applied.

         10. Whenever the Undersigned shall be in default as aforesaid,  without
demand or notice of any kind  except as set  forth  herein,  the  entire  unpaid
amount of all Obligations shall become immediately due and payable, and the Bank
may exercise, from time to time, any and all rights and remedies available to it
under the Uniform  Commercial  Code of Illinois,  or otherwise,  including those
available  under any written  instrument  (in addition to this Note) relating to
any of  the  Obligations  and  may,  without  demand  or  notice  of  any  kind,
appropriate  and apply  toward the payment of such of the  Obligations,  whether
matured or unmatured,  including  reasonable  costs of collection and reasonable
attorneys'  and  paralegals'  fees, and in such order of application as the Bank
may, from time to time,  elect,  any balances,  credits,  deposits,  accounts or
monies of the Undersigned in possession, control or custody of, or in transit to
the Bank.

         11. THE UNDERSIGNED  WAIVES THE BENEFIT OF ANY LAW THAT WOULD OTHERWISE
RESTRICT  OR LIMIT  THE BANK IN THE  EXERCISE  OF ITS  RIGHTS,  WHICH IS  HEREBY
ACKNOWLEDGED,  TO APPROPRIATE  WITHOUT  NOTICE,  AT ANY TIME  FOLLOWING  DEFAULT
(AFTER  GIVING  EFFECT  TO  APPLICABLE  GRACE  OR CURE  PERIODS,  IF  ANY),  ANY
INDEBTEDNESS MATURED OR UNMATURED,  OWING FROM THE BANK TO THE UNDERSIGNED.  THE
BANK MAY, FROM TIME TO TIME,  WITHOUT DEMAND OR NOTICE OF ANY KIND,  APPROPRIATE
AND APPLY  TOWARD THE PAYMENT OF SUCH OF THE  OBLIGATIONS,  AND IN SUCH ORDER OF
APPLICATION,  AS THE  BANK  MAY,  FROM  TIME TO  TIME,  ELECT  ANY AND ALL  SUCH
BALANCES, CREDITS, DEPOSITS, ACCOUNTS, MONIES, CASH EQUIVALENTS AND OTHER ASSETS
OF OR IN THE NAME OF THE UNDERSIGNED, THEN OR THEREAFTER WITH THE BANK.

         12. THE UNDERSIGNED WAIVES EVERY DEFENSE, CAUSE OF ACTION, COUNTERCLAIM
OR SET OFF  WHICH  THE  UNDERSIGNED  MAY NOT HAVE OR  HEREAFTER  MAY HAVE TO ANY
ACTION BY BANK IN ENFORCING THIS NOTE OR ANY OF THE OTHER OBLIGATIONS,  RATIFIES
AND  CONFIRMS  WHATEVER  THE BANK MAY DO PURSUANT TO THE TERMS HEREOF AND AGREES
THAT BANK SHALL NOT BE LIABLE FOR ANY ERROR OF  JUDGMENT  OR MISTAKES OF FACT OR
LAW EXCEPT FOR THOSE  ERRORS OR  MISTAKES  WHICH  RESULT  FROM THE BANK'S  GROSS
NEGLIGENCE  OR  WILLFUL  MISCONDUCT.  THE BANK AND THE  UNDERSIGNED,  KNOWINGLY,
VOLUNTARILY  AND  INTENTIONALLY  WAIVE  IRREVOCABLY THE RIGHT EITHER MAY HAVE TO
TRIAL BY JURY WITH RESPECT TO ANY LEGAL PROCEEDING BASED HEREON,  OR ARISING OUT
OF, UNDER OR IN CONNECTION  WITH THIS NOTE OR ANY OF THE OTHER  OBLIGATIONS,  OR
ANY AGREEMENT,  EXECUTED OR CONTEMPLATED TO BE EXECUTED IN CONJUNCTION  HEREWITH
OR ANY  COURSE  OF  CONDUCT  OR  COURSE  OF  DEALING  IN WHICH  THE BANK AND THE
UNDERSIGNED ARE ADVERSE PARTIES. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE
BANK GRANTING ANY FINANCIAL ACCOMMODATION TO THE UNDERSIGNED.

         13. The  Undersigned,  and any other party  liable with  respect to the
Obligations,   including  any   guarantors,   and  any  and  all  endorsers  and
accommodation  parties,  and each one of them,  waive  any and all  presentment,
demand,  notice of  dishonor,  protest,  and all other  notices  and  demands in
connection  with the  enforcement  of the  Bank's  right  hereunder,  and hereby
consent to, and waive notice of release, with or without  consideration,  of the
Undersigned.  No default shall be waived by the Bank except in writing. No delay
on the part of the Bank in the exercise of any right or remedy shall  operate as
a waiver thereof,  and no single or partial exercise by the Bank of any right or
remedy shall preclude other or further exercise thereof,  or the exercise of any
other  right or remedy.  This Note:  (I) is valid,  binding and  enforceable  in
accordance  with  its  provisions,   and  no  conditions   exist  to  the  legal
effectiveness  of this Note;  (ii)  contains  the entire  agreement  between the
Undersigned and the Bank; (iii) is the final expression of the intentions of the
Undersigned and the Bank; and (iv) supersedes all negotiations, representations,
warranties, commitments, offers, contracts (of any kind or nature, whether or al
or written) prior to or  contemporaneous  with the execution hereof. No prior or
contemporaneous representation, warranties, understandings, offers or agreements
of any kind or nature,  whether  oral or written,  have been made by the Bank or
relied upon by the  Undersigned  in  connection  with the execution  hereof.  No
modification,  discharge,  termination or waiver of any of the provisions hereof
shall be binding upon the Bank,  except as expressly set forth in a writing duly
signed and delivered on behalf of the Bank.

         14. The  Undersigned  agrees to pay all  reasonable  costs,  reasonable
legal expenses,  reasonable  attorneys fees and paralegals'  fees of every kind,
paid or incurred by the Bank in enforcing its rights hereunder,  including,  but
not limited to,  litigation  or  proceedings  initiated  under the United States
Bankruptcy Code, or in respect to any other of the Obligations,  or in defending
against any defense, cause of action, counterclaim,  set off or crossclaim based
on any act of  commission  or omission by the Bank with  respect to this Note or
any other of the  Obligations,  promptly  on demand of the Bank or other  person
paying or incurring the same.

         15. TO INDUCE THE BANK TO MAKE THE LOAN  EVIDENCED  BY THIS  NOTE,  THE
UNDERSIGNED  IRREVOCABLY  AGREES THAT ALL ACTIONS ARISING DIRECTLY OR INDIRECTLY
AS A RESULT OR IN CONSEQUENCE OF THIS NOTE OR ANY OTHER  AGREEMENT WITH THE BANK
SHALL BE  INSTITUTED  AND  LITIGATED  ONLY IN COURTS HAVING SITUS IN THE CITY OF
CHICAGO,  ILLINOIS,  AND  THE  UNDERSIGNED  HEREBY  CONSENTS  TO  THE  EXCLUSIVE
JURISDICTION  AND VENUE OF ANY STATE OR  FEDERAL  COURT  LOCATED  AND HAVING ITS
SITUS IN SAID CITY, AND WAIVES ANY OBJECTION BASED ON FORUM NON CONVENIENS.  THE
UNDERSIGNED HEREBY WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS,  AND CONSENTS
THAT ALL SUCH SERVICE OF PROCESS MAY BE MADE BY CERTIFIED  MAIL,  RETURN RECEIPT
REQUESTED,  DIRECTED TO THE  UNDERSIGNED AT THE ADDRESS  INDICATED IN THE BANK'S
RECORDS IN THE MANNER  PROVIDED BY  APPLICABLE  STATUTE,  LAW,  RULE OF COURT OF
OTHERWISE.

         16.  The loan  evidenced  hereby  has been  made and this Note has been
delivered at the Bank's main office.  This Note shall be governed and  construed
in accordance with the laws of the State of Illinois, in which state it shall be
performed,  and shall be binding upon the  Undersigned  and its  successors  and
assigns. If this Note contains any blanks when executed by the Undersigned,  the
Bank is hereby  authorized,  without notice to the Undersigned,  to complete any
such blanks  according  to the terms upon which the loan or loans were  granted.
Wherever  possible,  each  provision of this Note shall be  interpreted  in such
manner as to be effective and valid under  applicable  law, but if any provision
of this Note shall be prohibited by or be invalid under such law, such provision
shall be severable,  and be deemed ineffective to the extent of such prohibition
or invalidity  without  invalidating  the remaining  provisions of this Note. If
more than one party shall  execute  this Note,  the term  "Undersigned"  as used
herein shall mean all parties signing this Note and their respective  successors
and  assigns,  and  such  parties  shall,  as the case may be,  be  jointly  and
severally obligated hereunder.

         17.  The  Undersigned  represents  and  warrants  to the Bank  that the
execution  and  delivery of this Note has been duly  authorized  by  resolutions
heretofore  adopted by its Board of Directors and in accordance with law and its
bylaws,  that said resolutions  have not been amended or rescinded,  are in full
force and effect and that the officer or officers  executing and delivering this
Note for and on behalf of the  Undersigned  are duly  authorized  so to act. The
Bank, in extending  financial  accommodations  to the Undersigned,  is expressly
acting and relying upon the aforesaid representations and warranties.

         18.  The   Undersigned   acknowledges   and  agrees  that  the  lending
relationship  hereby  created with the Bank is and has been conducted on an open
and arm's  length basis in which no  fiduciary  relationship  exits and that the
Undersigned has not relied and is not relying on any such fiduciary relationship
in consummating the loan evidenced by this Note.

         19.  As used  herein,  all  provisions  shall  include  the  masculine,
feminine,  neuter,  singular and plural thereof,  wherever the context and facts
require such construction and in particular the word  "Undersigned"  shall be so
construed.

         20. The  Undersigned  has  reviewed  the areas  within its business and
operations  which  could be  adversely  affected  by,  and has  developed  or is
developing a program to address on a timely basis, the "Year 2000 Problem" (that
is, the risk that computer applications used by the Undersigned may be unable to
recognize and perform properly date-sensitive  functions involving certain dates
prior to and any date after December 31, 1999), and has made related appropriate
inquiry of material suppliers and vendors. Based on such review and program, the
Undersigned believes that the Year 2000 Problem will not have a material adverse
effect on the  Undersigned.  Upon the request of the Bank from time to time, the
Undersigned   shall   provide  the  Bank  with  such  updated   information   or
documentation  as the Bank may request  indicating  the status of its efforts to
resolve the Year 2000 Problem.

         21.  This  Note  is in  replacement  and  substitution  for,  but not a
repayment of, that certain $25,000,000  Revolving Note dated as of June 28, 1999
of the  Undersigned  payable to the order of the Bank and does not and shall not
be deemed to constitute a novation therefor.

         IN WITNESS WHEREOF,  the Undersigned has executed this Note on the date
above set forth.
