                         ANNUAL MEETING OF SHAREHOLDERS

                                       OF

                              HERCULES INCORPORATED

                        TO BE HELD ON [___________], 2003

                            ________________________


         We are the Hercules Shareholders' Committee for New Management (the
"Committee"). The Committee consists of (i) International Specialty Products
Inc., a Delaware corporation ("ISP") and the second largest shareholder of
Hercules Incorporated, a Delaware corporation ("Hercules" or the "Company"),
(ii) Samuel J. Heyman, Sunil Kumar, Gloria Schaffer and Raymond S. Troubh, four
members of the Company's Board of Directors who were elected at the Hercules'
2001 Annual Meeting of Shareholders (collectively, the "minority directors") and
(iii) Harry Fields, Anthony Kronman, Vincent Tese and Gerald Tsai, Jr., the
Committee's nominees to the Board of Directors.

         This solicitation is being conducted by the Committee and is being
funded by ISP. This proxy statement and the enclosed WHITE proxy card are being
furnished by the Committee to holders of shares of common stock of Hercules,
$25/48 stated value per share (the "Shares" or the "Common Stock"), in
connection with the solicitation of proxies to elect four nominees to the Board
of Directors of Hercules (the "Board of Directors") at Hercules' 2003 Annual
Meeting of Shareholders, and at any and all adjournments, postponements,
continuations or reschedulings thereof (the "2003 Annual Meeting").

         According to the preliminary proxy statement filed by Hercules (the
"Management Preliminary Proxy Statement") with the Securities and Exchange
Commission on [________], 2003, the 2003 Annual Meeting will be held on [_____],
2003 at [_______] a.m., local time, at [_____________], and the record date for
determining shareholders entitled to notice of and to vote at the 2003 Annual
Meeting is [_____], 2003 (the "Record Date").

         According to the Management Preliminary Proxy Statement, at the 2003
Annual Meeting, four members of the Board of Directors will be elected for
three-year terms expiring at the 2006 Annual Meeting of Shareholders (the
"2006 Annual Meeting"). In opposition to the solicitation of proxies by the
Board of Directors, the Committee is proposing and soliciting proxies in
support of a slate of four nominees for the Board of Directors to stand for
election to the Board of Directors. We are soliciting your proxy to vote at
the 2003 Annual Meeting for the election of our nominees, Harry Fields,
Anthony Kronman, Vincent Tese and Gerald Tsai, Jr. (collectively, the
"Nominees") as directors of Hercules in the class with a three-year term
continuing until the 2006 Annual Meeting and until their successors are duly
elected and qualified.


                                      1





         THIS SOLICITATION IS BEING MADE BY THE COMMITTEE AND NOT BY OR ON
BEHALF OF THE BOARD OF DIRECTORS OF HERCULES.

         As discussed in more detail under the heading "QUORUM AND VOTING" in
this proxy statement, shareholders who vote on the WHITE proxy card furnished by
the Committee will be able to vote for the election of the four Nominees. The
Nominees, if elected, together with the minority directors who were nominated by
ISP in 2001 and became directors of the Company following the 2001 Annual
Meeting of Shareholders (the "2001 Annual Meeting"), will constitute a majority
of the members of the Board of Directors and, since the Company's by-laws
provide that action by the Board of Directors requires a majority vote of the
directors present at a meeting at which a quorum is present, the four Nominees,
together with the minority directors, would be able to cause any action to be
taken or not taken by the Board of Directors.

         ISP may be deemed (solely for purposes of Rule 13d-3 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act")) to beneficially own (as
defined in Rule 13d-3 of the Exchange Act) 9,893,700 Shares of Common Stock,
representing approximately 9.1% of the outstanding Shares. Samuel J. Heyman, the
Chairman of the Board of ISP and a director of the Company, may be deemed
(solely for purposes of Rule 13d-3 of the Exchange Act) to beneficially own (as
defined in Rule 13d-3 of the Exchange Act) 100% of the outstanding shares of
common stock of ISP.

         This proxy statement and the enclosed WHITE proxy card are first being
furnished to shareholders on or about [_____], 2003.

         WE URGE YOU TO SIGN, DATE AND RETURN THE ENCLOSED WHITE PROXY CARD IN
FAVOR OF THE ELECTION OF OUR NOMINEES DESCRIBED IN THIS PROXY STATEMENT.

         YOUR VOTE AT THIS YEAR'S ANNUAL MEETING IS VERY IMPORTANT, NO MATTER
HOW MANY OR HOW FEW SHARES YOU OWN. PLEASE SIGN AND DATE THE ENCLOSED WHITE
PROXY CARD AND RETURN IT IN THE ENCLOSED POSTAGE-PAID ENVELOPE PROMPTLY.
PROPERLY VOTING THE ENCLOSED WHITE PROXY CARD WILL REVOKE ANY PROXY PREVIOUSLY
SIGNED BY YOU.

         PLEASE DO NOT RETURN ANY [COLOR] PROXY CARD SENT TO YOU BY HERCULES.
Even if you may have voted on Hercules' [color] proxy card, you can easily
change your vote and revoke that proxy by signing, dating and returning the
enclosed WHITE proxy card. ONLY YOUR LATEST DATED PROXY WILL COUNT AT THE 2003
ANNUAL MEETING.

         If you have any questions or need any assistance in voting your Shares,
please call the firm assisting us in the solicitation of proxies:

                                   BACKGROUND

         By way of background, we have been major Hercules shareholders for
almost three years. As a result of our dissatisfaction with the Hercules Board
and management, ISP waged a proxy contest at the Company's 2001 Annual Meeting,
at which Hercules shareholders elected ISP's four nominees to seats on the
Hercules Board. The minority directors have endeavored to work with Hercules
management and the remaining incumbent directors. Our efforts, however, have
been frustrated by management and the Board's majority directors, who, voting in
lockstep, have rebuffed our almost every initiative.1

         Although we continued to be sharply critical of the majority directors
and management for their conduct of the Company's affairs, which in our view has
contributed to the destruction of shareholder values at the Company, primarily
in order to provide the Company with one last opportunity to do the right thing
for shareholders, we decided not to wage a proxy contest for control of the
Board at the 2002 Annual Meeting. At the Annual Meeting last June, the minority
directors issued the following statement: "Hercules' majority directors and
management still have the opportunity to right themselves and maximize the
potential of the Company and its operating businesses, but they cannot do so
without promptly and fully addressing the issues [we have] outlined. We urge
them to accept that challenge."

         Unfortunately, that challenge continues to go unheeded, and we have
decided to wage a proxy contest this year for the four seats up for election,
because in our view there is no other way in which to help maximize shareholder
values for all Hercules shareholders. The Hercules Shareholders' Committee for
New Management includes our four current Hercules directors ("minority
directors") and four additional director nominees for this year's Annual
Meeting. Our directors and nominees represent the interests of all Hercules
shareholders, including those of the Company's second largest shareholder,
International Specialty Products Inc., which owns almost 10 million shares of
Hercules stock and has an investment in Hercules of more than $140 million.2

         In contrast, the four Hercules incumbent directors running for
reelection this year own in the aggregate only slightly more than 50,000
shares. You should know that Dr. Joyce, Hercules' Chief Executive, owns
157,230 shares, 156,330 of which were given to him in connection with the
Company's bonus program and 900 of which were given to him in the form of a
matching grant in connection with the Company's 401k program. To our
knowledge, Dr. Joyce has not purchased a single share of Hercules stock since
he came to the Company.

         As one of Hercules' major shareholders, our interests are clearly
aligned with yours, and we are committed to maximize value for all Hercules
shareholders as we have invested our own money in Hercules as you have.

--------

      1       You should know that our experience prompted us prior to the
              2002 Annual Meeting to propose - a proposal which was rebuffed -
              that if Dr. Joyce and his majority directors agreed to elect a
              new Chairman and CEO, acceptable to both majority and minority
              directors, we would abandon consideration of a proxy contest to
              acquire control of the Hercules Board at the 2002 Annual
              Meeting.

      2       ISP's investment is measured at cost.

             The Hercules Shareholders' Committee for New Management

                 The Committee's Four Current Hercules Directors

         The four minority directors who were ISP's nominees at the 2001 Annual
Meeting are:

         Gloria Schaffer - Mrs. Schaffer has had a distinguished career in
Government service, having held major positions in Connecticut, including
Secretary of State, Commissioner of the Department of Consumer Protection, and
State Senator for six terms. Ms. Schaffer was also a Member of the Federal Civil
Aeronautics Board and has served as a Board member of several public and private
companies.

         Raymond S. Troubh - Mr. Troubh has had broad financial experience,
including as a General Partner of Lazard Freres & Co. Mr. Troubh has served as
a Governor of the American Stock Exchange and as a Board member of Time Warner,
Inc., Becton, Dickinson and Company, and Starwood Hotels & Resorts, Inc., among
others. Mr. Troubh currently serves as the Non-executive Chairman of Enron
Corp., having joined that company's Board in the wake of its financial problems
last year. Mr. Troubh also currently serves as a director of Diamond Offshore
Drilling, Inc. and Gentiva Health Services, Inc., among others.

         Sunil Kumar - Mr. Kumar was Executive Vice President of
Bridgestone-Firestone, heading up that company's $3 billion national retail
store operations. Mr. Kumar served for three years as President and Chief
Operating Officer of Building Materials Corporation of America, the nation's
leading manufacturer of residential and commercial roofing. During this period,
BMCA increased its sales and operating income by approximately 60%. Mr. Kumar
has been Chief Executive of ISP, an international specialty chemicals company,
since June 1999.

         Samuel J. Heyman - Mr. Heyman began his career as a lawyer in the
United States Justice Department under Robert F. Kennedy and later served as
Chief Assistant United States Attorney, District of Connecticut (New Haven
Division). In 1968, Mr. Heyman left Government service to run Heyman Properties,
a small but growing family business, which he expanded into a successful,
national real estate development company.

         In 1983, Mr. Heyman and a slate of nominees representing shareholder
interests waged a successful proxy contest for control of GAF, in what Barron's
a leading financial publication, characterized as "one of the most striking
achievements in the annals of corporate finance." (Aug. 8, 1983). Mr. Heyman
served as GAF's Chairman and Chief Executive Officer (1983-2000) and is
currently the Chairman of ISP, a leading international specialty chemicals
company. Hercules shareholders should know that Mr. Heyman has been involved as
a shareholder activist or potential acquirer with respect to five public
companies, helping to create more than $7 billion of increased wealth for
shareholders of those companies, as illustrated below:3

--------

      3       There is, of course, no assurance that either the efforts of the
              Committee or Mr. Heyman will result in similar benefits for
              Hercules shareholders.

The Committee's Four Director-Nominees

         Harry Fields - Mr. Fields served as an executive for more than forty
years at International Flavors and Fragrances Inc., where he served as
President of the International Flavor Division and as a member of its Board of
Directors. He currently is President of Fields Associates, Ltd., a company
specializing in joint ventures between U.S. and foreign companies, and served
as a director of OPTA Food Ingredients, Inc.

         Anthony T. Kronman - Mr. Kronman is currently Dean of Yale Law School.
Mr. Kronman became a director of Adelphia Communications Corporation after its
filing of a voluntary petition for reorganization under Chapter 11 of the
United States Bankruptcy Code.

         Vincent Tese - Mr. Tese has had a distinguished career in Government
service, having held such prominent positions as New York State Superintendent
of Banks, Director of Economic Development for the State of New York, and
Chairman and Chief Executive Officer of the Urban Development Corporation. Mr.
Tese is currently the Chairman of Wireless Cable International Inc. and is a
member of the Board of Directors of Bear Stearns Companies Inc., Bowne & Co.,
Inc., Cablevision Systems Corp. and Mack-Cali Realty Corp., among others.

         Gerald Tsai, Jr. - Mr. Tsai was Chairman and Chief Executive Officer
of Primerica Corporation, a diversified financial services company, and served
as Chairman of the Board, President and Chief Executive Officer of Delta Life
Corporation, a life insurance and annuity company. Mr. Tsai currently serves as
a member of the Board of Directors of Sequa Corporation, Zenith National
Insurance Corporation, Triarc Companies, Inc., and United Rentals, Inc., among
others.


--------

      4       GAF was acquired by Mr. Heyman and a management group in 1989 at
              $53 per share. Union Carbide implemented a recapitalization of
              its own in response to GAF's premium bid for the Company that
              resulted in a market value immediately thereafter of $85 per
              share. Borg Warner, Dexter and Life Technologies were acquired
              by third parties after GAF or ISP made premium offers for those
              companies.


                                      6



         Additional information regarding the nominees is contained in this
proxy statement under the heading "THE NOMINEES."

                          REASONS FOR OUR SOLICITATION

         Under Dr. Joyce's management, the Company's financial and stock price
performance have been in our opinion disastrous. Moreover, we believe that
Hercules has been a case study in the failure of corporate governance. In
addition, we believe that Dr. Joyce and the Hercules Board were responsible for
selling the Company's best business at the worst possible time and that
management's poor business judgment was in no small measure responsible for the
Company's almost $570 million pension fiasco.

         The Committee's four director-nominees, if elected, will, when combined
with our four minority directors, constitute a majority of the Board and will be
in a position to not only avoid the mistakes of the past but cause the Hercules
Board to take positive actions designed to increase shareholder value, such as:

o        Focus on the "hands-on" management of Hercules' businesses and
         successful, bottom-line operating and growth strategies, both short and
         long term, and strengthen the Hercules management team. We intend to
         elect a new, highly qualified, full-time, "roll up your sleeves" Chief
         Executive committed to the turnaround of the Company's businesses, who
         will reside in the Wilmington area and whose compensation will be
         designed to closely align his or her interests with those of Hercules
         shareholders. Finally, we will devote high-level attention to not only
         the turnaround of Hercules' operating businesses but also the
         management of the Company's critical, non-operating issues, such as the
         minimization of its pension exposure.

o        Remove or substantially modify the Company's poison pill, which
         prevented Hercules shareholders, in October 2000, from accepting ISP's
         $17.50 per share offer for 25 million shares - thereby costing Hercules
         shareholders more than $200 million.5

o        Recommend that shareholders remove a Hercules election Bylaw, which the
         Company claims requires the affirmative vote of the holders of a
         majority of all outstanding shares for the election of directors (the
         "Bylaw Vote Provision"). As further detailed in the Section below
         captioned "DR. JOYCE AND THE HERCULES BOARD REFUSE TO NULLIFY A COMPANY
         BYLAW THAT DISENFRANCHISES ITS SHAREHOLDERS", the Bylaw Vote Provision,
         in the Committee's view, disenfranchises shareholders, is highly
         unusual (virtually all companies provide for a plurality vote in the
         election of directors), and is inconsistent with good corporate
         governance. Moreover, the Committee believes that the Bylaw Vote
         Provision can have the effect of entrenching the current Board of
         Directors, because if no nominee receives a majority vote of the
         outstanding Shares, the incumbent directors would remain in place as
         "holdover" directors.

--------

      5       Cost to Hercules shareholders calculated on the basis of $17.50
              per share less the Company's stock price of $9.44 per share, as
              of April 15, 2003.


                                      7


                    THE COMPANY'S PERFORMANCE IN OUR OPINION
                   HAS GONE FROM BAD TO WORSE UNDER DR. JOYCE

         When measured by virtually any financial yardstick, the Company's
record in recent years under Dr. Joyce and his predecessors, has, in our
opinion, been disastrous.

Consider the Following:

o        After reaching a high of $66.25 on March 19, 1996, Hercules' stock
         price has lost more than 85% of its value, wiping out more than $6
         billion in shareholder value. Since Dr. Joyce was named Chief Executive
         on May 8, 2001, the price of Hercules stock (which has paid no
         dividends since that time), as of April 3, 2003, had lost almost 25% of
         its value, while the S&P MidCap Specialty Chemicals Index increased by
         3.8% (including dividends) over the same period of time.6

o        Hercules' financial performance has in our opinion gone from bad to
         worse under Dr. Joyce, prompting a financial columnist (Christopher
         Byron, February 17, 2003, New York Post) to characterize Hercules as
         "spewing red ink in all directions". Under Dr. Joyce, the Company has
         been unprofitable in 5 out of the last 6 reported quarters, registering
         almost $320 million in after-tax losses (even excluding a $368 million
         write-down of "goodwill"). For the 6 full reported quarters since Dr.
         Joyce became CEO, even adjusting for almost $385 million in net,
         after-tax, "non-recurring" charges, the Company has managed to register
         only $64 million in "pro forma" earnings -- or little more than an
         average of $0.39 per share per annum.

o        Dr. Joyce, operating as his own Chief Financial Officer, has become in
         our opinion the master of the one-time, "non-recurring" charge, taking
         substantial "non-recurring" charges in all 6 full reported quarters
         since he came to Hercules -- and doing so in a manner which implies
         that these charges or "adjustments" are one-time items.

o        Even after adjusting for "one-time" charges and goodwill amortization,
         Hercules' financial performance has been extremely disappointing, with
         2002 earnings being only slightly more than 50% of the results for 2000
         (the last full year prior to Dr. Joyce's arrival at Hercules). Pro
         forma earnings per share for 2000-2002 have been as follows:7

--------

      6       On May 8, 2001, the day Dr. Joyce was elected Chief Executive
              Officer, Hercules shares closed on the New York Stock Exchange
              at $12 per share.

              We believe that the S&P MidCap Specialty Chemicals Index,
              which consists of 8 specialty chemicals companies with a mean
              market capitalization of $1.16 billion, is the most relevant
              index, although it should be noted that Hercules, starting
              more than 20 years ago when it was a completely different and
              much larger company, has been listed in the S&P 500 Chemicals
              Index. We do not believe that that index, which is comprised
              of 14 companies, with Hercules being by far the smallest, and
              includes Dupont and Dow and other companies with a mean market
              capitalization of $8.94 billion, is an appropriate reference
              point with regard to Hercules' performance. Incidentally,
              Hercules' stock price has substantially underperformed even
              the S&P 500 Chemicals Index over the relevant time frame.

      7       The 2000 pro forma earnings per share includes earnings and
              related interest expenses for the BetzDearborn business and
              excludes goodwill amortization consistent with the Company's pro
              forma earnings for 2001 and 2002. The pro forma 2001 and 2002
              earnings per share exclude the earnings and related interest
              expenses for the BetzDearborn business which was sold.

                  2002      $0.63

o        Moreover, Hercules' financial performance (again even after adjustment
         for non-recurring charges and on a pro forma basis) continues to lag
         the specialty chemicals industry (as measured by 8 companies in the S&P
         MidCap Specialty Chemicals Index). In 2002, for example, Hercules
         revenue growth was only 2.5% compared with 5.7% for the weighted
         average of companies in the Index, while its return on assets and sales
         were only approximately 50% and 70%, respectively, of the returns for
         the same 8 companies (excluding goodwill writedowns).

                DR. JOYCE'S RECORD AT UNION CARBIDE - DISASTROUS
                    FINANCIAL PERFORMANCE, BROKEN PROMISES,
                          AND OUTRAGEOUS COMPENSATION

         Prior to coming to Hercules, Dr. Joyce spent his entire business career
at Union Carbide, and you should be aware of these FACTS concerning his record
as Union Carbide's Chief Executive (1995 - 2000):

o        Under Dr. Joyce's leadership, Union Carbide's net income declined from
         $925 million in 1995 to $162 million in 2000 - down an astounding 82%
         - making Union Carbide's performance the worst in the S&P 500
         Chemicals Index (consisting of the 15 largest Chemicals companies at
         that time).

o        Despite Dr. Joyce's cost cutting efforts at Union Carbide, the
         Company's operating margins declined from 16.2% to 2.7% from 1995 to
         2000, regularly ranking the company in the bottom quartile of the S&P
         Chemicals Index for return on assets, including last in Dr. Joyce's
         final year.

o        Dr. Joyce's credibility with Union Carbide shareholders was undermined
         by repeated broken promises.

o        In 1997, Dr. Joyce advised analysts that Union Carbide planned to meet
         or exceed a 15% return on capital over the course of the chemical
         cycle, while earning an 8% return at the trough. In fact, Union
         Carbide's returns on capital were actually 3% at the trough of the
         chemical industry cycle in 2000.

o        In early 1999, Dr. Joyce advised Union Carbide shareholders that the
         Company was "in good shape entering 1999". In fact, operating income
         was down 30% in 1999 compared with the previous year.

                                      9



o        On July 26, 1999, little more than 60 days before the end of the
         quarter, Dr. Joyce advised Union Carbide shareholders that "prospects
         for improved third quarter

         earnings appear encouraging based upon current conditions." In fact,
         operating income was down in the third quarter compared to both the
         previous quarter and the same quarter in 1998.

o        One commitment that Dr. Joyce staked his reputation on was his
         often-repeated promise that Union Carbide would earn a minimum of $4
         per share in 2000. In a grandstand move, characterized in an October
         13, 1997 Business Week article entitled, "Smoke, Mirrors, and the
         Boss' Paycheck," as "clever public relations .... unlikely to dent
         Joyce's wallet or stoke up Union Carbide's performance," Dr. Joyce
         committed to forfeit his salary if Union Carbide did not earn $4 per
         share in 2000. As it turned out, Union Carbide's earnings for 2000
         were $1.18 per share, and, notwithstanding his public commitment Dr.
         Joyce took his full salary and bonus anyway!

o        Notwithstanding Union Carbide's dismal performance during the five
         years that he was Chief Executive, Dr. Joyce's total annual
         compensation increased from $8.8 million per annum in 1995 to $23.3
         million per annum in 1999 - up more than 165%.8

o        Finally, after five years of Dr. Joyce's leadership at Union Carbide,
         the Company was acquired by Dow Chemical. Of Dr. Joyce's tenure at
         Union Carbide, James Kelleher of Argus Research observed in a Delaware
         News Journal article (May 17, 2001), entitled "Hercules Chief Knows
         Trouble," "I think he had a better reputation as a scientist than an
         administrator. He did virtually nothing with the Company." Similarly,
         in the same article, Paul Leming, an ING Barings security analyst, is
         quoted on the subject of Union Carbide's condition at the end of Dr.
         Joyce's tenure - "Carbide had to do that deal. The wheels were coming
         off." Finally, a Business Week article entitled, "Formula For A
         Perfect Marriage" (Diane Brady, August 16, 1999) observed, "For the
         team in Danbury, the deal is bound to be bittersweet. Union Carbide
         has faced a litany of woes in recent years, from troubled partnerships
         in places like Kuwait to delayed plant openings. Joyce also spent
         heavily on new facilities, but the payoff eluded his company."

               THE BETZDEARBORN SALE - DR. JOYCE AND THE HERCULES
                   BOARD, AFTER REFUSING TO SEEK SHAREHOLDER
                  APPROVAL, SELL WHAT WE SAW AS THE COMPANY'S
                        BEST BUSINESS AT THE WORST TIME

         Last year's sale of the Company's BetzDearborn business to General
Electric was in our view a major strategic mistake. Moreover, this transaction
has unfortunately had the effect of


--------

      8       2000 numbers are not available because of the Dow merger. Total
              annual compensation includes, as per Union Carbide's proxy
              statements, stock option grants, assuming 10% per annum
              appreciation.


                                      10

significantly reducing the future value of the Company and the upside with
respect to all of our investments.

         By way of background, Hercules' $3.1 billion acquisition of
BetzDearborn in 1998, which has been characterized by Paul Leming as "one of the
worst acquisitions in the history of the chemicals industry" (July 18, 2000), is
a dramatic example of the Company's "buy high-sell low" strategy. For the
subsequent sale last year consisted of most of the BetzDearborn businesses
originally acquired by Hercules, with the net sale price being the equivalent of
1.7 x sales compared to the 2.4 x sales paid by Hercules in 1998.

         You should know that last year's decision to sell BetzDearborn was
taken by an 8-5 vote over the objection of the four minority directors and one
incumbent director (not one of Dr. Joyce's hand-picked directors, but rather a
director elected during the term of a previous management). The sale would have
only made sense, in our opinion, had the Company no other way to refinance its
debt. For private sale multiples in the chemicals industry in 2001 (when the
price was established) were at their lowest levels in more than 10 years.

         What Hercules at the time of the sale failed to communicate, to both
its shareholders and Wall Street analysts who follow the Company, is that it had
available what we believe to have been a superior alternative. For, prior to the
Company's decision to sell BetzDearborn, major banks offered the Company an
attractive refinancing package which would not have required the Company to make
ill-timed asset sales.

         Sale proceeds, after taxes and transaction costs, amounted to
approximately 6 x estimated 2002 EBITDA, while the Company's public stock price
at the time was trading at a multiple of approximately 7 x EBITDA -- a move
hardly calculated to increase shareholder value! Moreover, the sale was made at
a time when forward operating profits for the business were estimated by
Hercules to increase substantially as a result of cost reductions already
implemented. Finally, the sale of the business has substantially diluted the
Company's earnings due in part to the fact that Hercules was required to utilize
the net sale proceeds to pay down debt carrying relatively low interest rates
(approximately 5% on average).

         You should know that the Hercules Board action approving the sale was
taken notwithstanding the fact that other major, institutional Hercules
shareholders, together with ourselves, had urged Dr. Joyce to reject the sale
and retain the BetzDearborn business. Moreover, when the minority directors
requested that the motion approving the transaction be amended to require that
the sale be submitted to a shareholders' vote, they were ruled "out of order",
and the issue of shareholder approval was never submitted to a vote of the
Board.

         Don't you believe that, where there is significant question concerning
a course of action involving a substantial sale of assets (at a price the
equivalent, for example, of almost twice the Company's entire market value), Dr.
Joyce and the Board, knowing of significant shareholder opposition, should have
submitted the matter to a vote of Hercules shareholders even when they may not
have been legally required to do so?

                      THE REVOLVING DOOR AT HERCULES - SIX
                         CHIEF EXECUTIVES IN SIX YEARS

         One of the primary responsibilities of a Company's Board of Directors
is to choose, attract, evaluate, retain, properly motivate, and manage by
appropriate objectives capable chief executives. By this standard of
measurement, in our opinion, the Hercules Board in recent years has been an
extraordinary failure.

         Between 1996-2001, Hercules had six different Chief Executives,
awarding one an estimated $14.25 9[fn] million severance package for three
years of service and another a $6 million package after only 16 months on the
job. Dr. Joyce came to Hercules in May, 2001 after having retired from Dow
Chemical upon selling Union Carbide in February 2001, lives in Connecticut
more than 200 miles from the Hercules Wilmington headquarters, and has been
unwilling to relocate to the Wilmington area.

         Finally, the Hercules Board's sorry record in our opinion is most
starkly illustrated by its failure to provide Dr. Joyce with sufficient
guidance and direction in terms of establishing the Chief Executive's
objectives and then holding him accountable for meeting them. In fact, the
objectives set forth by the Board's Compensation Committee were limited almost
exclusively to cost reduction and other measurements directly related thereto.
By way of just one example, management of the Company's two principal
non-operating issues, Hercules' pension and asbestos exposures, which resulted
last year in pre-tax charges to earnings of more than $600 million, were not
even mentioned in Dr. Joyce's 2002 management objectives.

         Consonant with the Board's failure, aside from reductions to an
obviously bloated cost structure, we have seen no evidence of any focus
whatsoever on a turnaround strategy, long range or short term growth strategies,
upgrading of the organization, attracting outstanding people to the Company, or
the hundreds of other matters so basic to operating a large corporation. Even
Dr. Joyce acknowledged in a quarterly earnings call last year that his
management focus has been almost entirely on cost reduction. This short-term
strategy presumably led Leslie Ravitz, a chemicals analyst at Morgan Stanley, to
question Hercules' long-term prospects (November 2, 2001) and has since been
further illustrated by Dr. Joyce's sharp cuts in both research and development
and capital expenditures.

         To add insult to injury, in February of this year, after the Company
had posted a loss of $248 million (excluding a $368 million write-down of
goodwill) for the 2002 year, and Hercules shareholders had lost another
approximately $400 million during the previous year, the Hercules Board, over
the objection of the minority directors, awarded executive bonuses to 135 senior
executives in the amount of almost $10 million (representing 193% of their
targeted bonuses) - including a $1.9 million bonus for Dr. Joyce! This followed
action by the Hercules Board in the previous year, notwithstanding the Company's
$58 million loss in 2001, awarding, again over our objection, executive bonuses
to 214 senior executives of almost $9 million - including a $1 million bonus for
Dr. Joyce for his seven months on the job in 2001!

                      HERCULES' $570 MILLION PENSION FIASCO

         Over the last three years, including almost two full years under Dr.
Joyce's management, Hercules pension plans, in addition to their failure to earn
their minimum investment hurdle rate, have in fact lost more than $250 million
as a result of negative investment returns. This enormous loss required the
Company earlier this year to take a pre-tax charge to equity of almost $570
million, which has now resulted in a negative equity for the Company of $123
million.

         While other Companies to be sure have been plagued in past years by
investment underperformance in their pension plans, the seriousness of the
Hercules' situation was underscored late last year in a Credit Suisse First
Boston report entitled, "The Magic of Pension Accounting," which estimates that
of 360 S&P 500 companies with defined benefit pension plans, Hercules'
underfunded status ranks it in the 14th worst position when compared to its
equity market capitalization. In addition, the report predicted that Hercules
may very well be required to incur the 5th largest after tax charge as a
percentage of equity in the fourth quarter of 2002.10

         Hercules' pension performance over the last several years is in no
small measure the result of management's asset allocation decision to invest
approximately 70% of its pension assets in equities, including almost 30% of
that amount in international equities. Incredibly enough, Hercules' investment
policy has allocated nothing to alternative assets, hedge funds, or so-called
"market neutral" investments, which tend to focus on delivering consistent
absolute returns with low correlation to the U.S. stock market or other asset
classes. When one considers the size of the Company's pension assets compared
with the size of Hercules, the fact that the Company's pension liabilities are
essentially fixed and relatively mature inasmuch as retirees and inactives
outnumber actives in the plan by an 8-to-1 ratio, Hercules' asset allocation
policy has been in our opinion wholly inappropriate and unduly risky.

         You should know the Hercules pension plan has been largely run on
autopilot for at least the last 10 years. Despite the importance of the pension
plan's performance to the overall financial performance of the Company as a
result of the size of the plan, there is in our view no one at Hercules that has
demonstrated the slightest expertise in this area. What is more, during Dr.
Joyce's tenure, until this issue reached crisis proportions, neither the Board
nor its Finance Committee had ever conducted a meaningful review of management's
investment decisions. While companies normally make pension asset allocation
decisions on as often as a quarterly or at least annual basis, Hercules,
seemingly oblivious to the vicissitudes of the investment climate over the last
10 years, had made no significant change to its investment policy during this
entire period of time, including the last two years under Dr. Joyce. At the very
least, this underscores the Company's need for a CFO, which we urged upon Dr.
Joyce and the Board almost two years ago.

--------

      10      The size of Hercules' fourth quarter charge has now materialized
              almost as predicted, but whether this charge amounts to the
              fifth largest cannot be easily ascertained.


                                      13


                      DR. JOYCE PACKS THE BOARD WITH FIVE
                             HANDPICKED DIRECTORS


         The record over the years at Hercules is replete with examples of
Boards who in our opinion do very little to safeguard the interests of the
Company's shareholders and are almost always supportive of whatever the Chief
Executive wants, failed Chief Executives who receive what we view as exorbitant
parachute payments, and Board members who until well after our 2001 proxy
contest were permitted to fund with Company monies million dollar gifts to their
favorite charities.11

         Taking advantage of a charter provision which permits the addition of
new directors without shareholder approval, no sooner had the votes been
counted in connection with the 2001 proxy contest, when Dr. Joyce, whose own
"election" was not originally submitted to shareholders either, together with
the nominating committee, thumbed their noses at Hercules shareholders by
choosing Paula Sneed, an incumbent director who had been defeated in that
contest for reelection, to fill an existing Board opening. Since that time,
Dr. Joyce, acting in concert with the Board's nominating committee, has
handpicked Messrs. Wyatt, Kennedy, Lipton, and Hunter (three of whom are
former or current executives in the commodity chemicals industry), to either
replace departing directors or fill existing openings. We believe that these
four directors have one common qualification for the job, a close relationship
with Dr. Joyce, and it should not surprise you that none of the five
handpicked directors (including Paula Sneed who resigned earlier this year)
have voted against Dr. Joyce's positions on a single issue.

         As further evidence of Dr. Joyce's view of shareholder democracy, at
the minority directors' first Board meeting in June, 2001, the Nominating
Committee proposed that seven of the eight then majority incumbent directors
each be given one of two major committee assignments - Audit or Compensation.
None of the four minority directors were proposed for membership on either of
these committees.12 When the minority members protested that they were the only
Hercules directors with a real mandate from the Company's shareholders, they
were told that this was the way committee assignments were made at Hercules and
that Board members had, in words to the effect "work their way up" to qualify
for major committee assignments. Parenthetically, Lipton and Kennedy, who were
elected to the Board after the four minority directors, were appointed shortly
thereafter to the Audit and Compensation Committees - so much for the Hercules
seniority system!

--------

      11      This last practice was stopped at the insistence of our minority
              directors some months after we joined the Board in 2001.

      12      At a later time, one of our minority directors received major
              committee assignments, although the three other minority
              directors still have not.

                      HERCULES' POISON PILL COSTS HERCULES
                       SHAREHOLDERS MORE THAN $200 MILLION

         In October 2000, in order to increase its investment in the Company,
ISP proposed a tender offer to all Hercules shareholders to purchase 25 million
additional shares of Hercules stock for $17.50 per share in cash. However,
because of the Company's poison pill, its offer required Board consent. Despite
repeated requests that Hercules permit it to proceed, the Board refused to do so
- thereby costing Hercules shareholders more than $200 million.

         You should know that the Hercules poison pill, with its unusually low
10% trigger point, was adopted in August, 2000, less than two weeks after ISP
publicly reported acquiring 9.9% of Hercules shares, notwithstanding the fact
that Hercules shareholders in the past had voiced strong opposition to the
poison pill. In 1991, a non-binding proposal to redeem Hercules' then-existing
poison pill, or submit it to a shareholder vote, was approved by shareholders.
Despite this earlier shareholder vote, the Hercules Board refused to seek
shareholder approval for the current pill adopted in 2000.

         Ask yourself whether the poison pill device is in your best interest
and whether you need to be "protected" from making your own decision to sell
your shares. We believe that it is paramount that YOU have the right to consider
for yourself the merits of offers for your shares. Our nominees will advocate
that the Board remove, or substantially revise, barriers to offers for your
shares so that you can make your own decisions.

              DR. JOYCE AND THE HERCULES BOARD REFUSE TO NULLIFY A
              COMPANY BYLAW THAT DISENFRANCHISES ITS SHAREHOLDERS

         The disregard of Dr. Joyce and the Hercules Board for the interests of
the Company's shareholders is dramatically demonstrated by their refusal to
rescind a Hercules election Bylaw which the Board claims requires an affirmative
vote of the holders of a majority of all outstanding shares for the election of
directors, instead of the greatest number of votes actually cast at an Annual
Meeting (a plurality vote). This means, for example, that if each Committee
nominee receives 50 million votes and each incumbent director receives only 10
million votes, the incumbents would retain their seats on the Board because the
Committee nominees would not have received a majority vote of approximately 108
million outstanding shares of Hercules common stock.

         This voting requirement disenfranchises shareholders, is highly unusual
if not unique, and in our view is inconsistent with good corporate governance.
In fact, we are unaware of a single other public company that has such a
provision with regard to election of directors. In our view, the Hercules Bylaw,
as interpreted by the Company, serves as a mechanism to entrench the current
Board, because if no nominee receives a majority vote of the outstanding shares,
the incumbent directors would remain in place beyond their three-year term, even
if our nominees received a plurality vote.

         As early as 2001, after calling to Hercules' attention this obvious
inequity and requesting that it take the necessary action to remedy this
situation in connection with the 2001 Annual Meeting, the Hercules Board



                                      15





refused to do so. As it turned out, three of the four minority directors were
elected at the 2001 Annual Meeting by more than 50% of the outstanding shares,
and Hercules agreed to seat the fourth minority director, who had won by a
plurality of those voting, in order to avoid a court test. After joining the
Board, the minority directors again proposed that Dr. Joyce and the Hercules
Board take action to effectively nullify the Bylaw, but they have refused to
do so.

         You should know that in a Delaware News Journal article (March 14,
2001) entitled, "Hercules' Election Method Is Fought", the Hercules voting
requirement prompted the following comments from a Wall Street analyst as well
as a corporate governance expert: Gary Hindes, Managing Director of New York's
Deltec Asset Management stated that, "These people [referring to the Hercules
directors] have managed to destroy what was a wonderful company," and is further
reported to have stated that Hercules should be asking for the resignation of
its directors, not supporting them for re-election; and Charles Elson, Director
of the Center for Corporate Governance at the University of Delaware,
characterized Hercules' voting provision as "highly unusual" and further stated,
"In all my years [of tracking corporate policies], I have not seen that with the
election of a board."

                       THE COMMITTEE'S PROGRAM TO REALIZE
                           HERCULES' UNDERLYING VALUES

         The Committee is convinced that there are strong underlying values at
Hercules and that the Company's two remaining, primary businesses, the pulp and
paper and Aqualon businesses, under the right direction, have substantial
potential for growth. As major shareholders, we are determined to maximize our
Company's underlying values for all Hercules shareholders.

         To this end, we would pursue the following program:

      (1)   Conduct a thorough search for a new, highly qualified, full-time,
            "roll up your sleeves" Chief Executive committed to the turnaround
            of the Company's businesses, who will reside in the Wilmington area
            and whose compensation will be designed to closely align his or her
            interests with those of Hercules shareholders. By making the right
            selection and establishing comprehensive goals and objectives, we
            intend to avoid the extraordinarily harmful turnover of Chief
            Executives at Hercules over the last six years.

      (2)   Rebuild management ranks which have been allowed to atrophy under
            the current Chief Executive and his predecessors. This will include
            the election of a first rate Chief Financial Officer, a position
            which Dr. Joyce and the Board have inexplicably refused to fill
            during his two-year term at the Company despite Hercules' myriad
            financial challenges.

      (3)   Eliminate excessive compensation and bonuses as have been enjoyed
            by Dr. Joyce and his other Board members and make certain that in
            the future compensation arrangements at Hercules provide that
            executive salaries, bonuses, and benefits be closely related to
            overall corporate, individual, and stock performance. In this
            regard, it is our view that an effective belt-tightening program
            must start at



                                      16




            the top, and that the kind of compensation enjoyed by Dr. Joyce is
            not only unwarranted in and of itself, but serves also to stiffen
            the resistance of others at Hercules to the kinds of cost-cutting
            measures which may be necessary.

      (4)   Despite the axiom that businesses cannot "cost cut their way to
            prosperity" and that successful turnaround strategies can never
            rely on cost reduction alone, management's overriding
            preoccupation, as acknowledged by Dr. Joyce, has unfortunately been
            on cost reduction alone. But dynamic leadership isn't just about
            cutting costs or staying afloat. In addition to cost-reduction, we
            would focus on new products, acquisitions, expanded field technical
            services, new alliances with other manufacturers to add
            complementary products, and a rational pricing strategy which
            places a high priority on profitability rather than on small market
            share gains.

      (5)   We believe that incumbent management has neither the qualifications
            nor the expertise to address the Company's two principal
            non-operating issues - the minimization of its pension and asbestos
            exposures. While current management in our view has given these
            critical issues short shrift, we would focus the attention of
            senior management, assisted by the best outside professionals, on
            these areas.

                                     GENERAL

Proxy Information

         As of the Record Date, ISP may be deemed (solely for purposes of Rule
13d-3 of the Exchange Act) to be the beneficial owner of 9,893,700 Shares. The
Shares beneficially owned by ISP represent approximately 9.1% of the Shares
outstanding and entitled to vote on the Record Date. Samuel J. Heyman, ISP's
Chairman and a director of the Company, may be deemed (solely for purposes of
Rule 13d-3 of the Exchange Act) to beneficially own 100% of the outstanding
shares of common stock of ISP. Additional information relating to the ownership
of Shares by the other members of the Committee is set forth in Annex A.

         The Shares represented by each WHITE proxy card which is properly
executed and returned will be voted at the 2003 Annual Meeting in accordance
with the instructions marked thereon. Executed but unmarked WHITE proxy cards
will be voted FOR the election of the four Nominees and will ABSTAIN with
respect to the ratification of PricewaterhouseCoopers LLP ("PWC") as the
independent public accountants of Hercules for 2003. An "Abstain" vote on the
ratification of PWC as Hercules' independent public accountants will have the
same effect as a vote against such matter. If any other matter properly comes
before the 2003 Annual Meeting, the named proxies will vote all proxies granted
to them in their sole discretion.

Proxy Revocation

         Whether or not you plan to attend the 2003 Annual Meeting, the
Committee urges you to vote FOR the election of the Nominees by signing, dating
and returning to Georgeson Shareholder Communications Inc. ("Georgeson") the
WHITE proxy card in the enclosed envelope. You can do this even if you may have
voted on the [color] proxy card solicited by the Board of Directors. It is only
the latest dated proxy that counts.

         Execution of a WHITE proxy card will not affect your right to attend
the 2003 Annual Meeting and vote in person. Any shareholder granting a proxy
(including a proxy given to Hercules) may revoke it at any time before it is
voted by (i) submitting a duly executed new proxy bearing a later date, (ii)
attending and voting at the 2003 Annual Meeting in person, or (iii) at any time
before a previously executed proxy is voted, giving written notice of revocation
either to Hercules Shareholders' Committee for New Management c/o Georgeson
Shareholder Communications Inc., 17 State Street, New York, NY 10004, or to
Hercules, 1313 North Market Street, Wilmington, Delaware, 19894-0001, Attention:
Corporate Secretary. Merely attending the 2003 Annual Meeting without voting at
the 2003 Annual Meeting will not revoke any previous proxy which has been duly
executed by you.

         After signing the enclosed WHITE proxy card, do not sign or return the
[color] proxy card unless you intend to change your vote, because only your
latest dated proxy card will be counted.

         Please review this document and the enclosed materials carefully. YOUR
VOTE IS VERY IMPORTANT, no matter how many or how few Shares you own.

         If you have any questions about giving your proxy or require
assistance, please call:

                                QUORUM AND VOTING

Voting Procedures

         You are eligible to execute a WHITE proxy only if you owned the Common
Stock on the Record Date. According to the Management Preliminary Proxy
Statement, the Board of Directors has set [____], 2003 as the Record Date for
determining those shareholders who will be entitled to notice of and to vote at
the 2003 Annual Meeting. Shareholders will have one vote for each Share of
Common Stock they own with respect to all matters to be considered at the 2003
Annual Meeting. You will retain the right to execute a proxy card in connection
with this proxy solicitation even if you sell your shares after the Record Date.
Accordingly, it is important that you vote the Shares held by you on the Record
Date, or grant a proxy to vote such Shares on the WHITE proxy card, even if you
sell such Shares after the Record Date.

         Unless otherwise indicated, the WHITE proxy authorizes the persons
named in the proxy to vote, and such persons will vote, properly executed and
duly returned proxies FOR the Nominees. If no instruction is given on your
executed WHITE proxy with respect to the ratification of the appointment of
Hercules' independent public accountants, the persons named in the WHITE proxy
will abstain from voting on such matter.

Vote Required

         Hercules will furnish shareholders with a definitive proxy statement
(the "Management Proxy Statement") in connection with the Board of Directors'
solicitation of proxies at the 2003 Annual Meeting. Information concerning the
number of Shares of Common Stock outstanding and entitled to vote on the Record
Date is required to be set forth in the Management Proxy Statement and, in
accordance with Rule 14a-5(c) under the Exchange Act, reference is made to the
Management Proxy Statement for such information. Only shareholders of record at
the close of business on the Record Date are entitled to notice of and to vote
on matters that come before the 2003 Annual Meeting.

         According to Hercules' by-laws, a quorum will exist at the 2003 Annual
Meeting if holders of not less than a majority of the Shares of Common Stock
issued and outstanding and entitled to vote at the 2003 Annual Meeting are
present in person or by proxy. If a quorum is present, the election of directors
requires the following vote:

         o       Hercules' claims that its by-laws require that in order to be
                 elected, nominees for director must receive the affirmative
                 vote of a majority of all issued and outstanding Shares
                 entitled to vote at the meeting. The Committee disagrees with
                 this interpretation and believes that the four nominees who
                 receive the greatest numbers of votes cast at the 2003 Annual
                 Meeting should be elected as directors.

                                      20


Method of Counting Votes

         The holders of not less than a majority of the number of Shares of
Common Stock issued and outstanding and entitled to vote at the 2003 Annual
Meeting must be represented in person or by proxy in order to constitute a
quorum for the transaction of business. Abstentions and broker non-votes, if
any, will be counted for purposes of determining whether a quorum exists.

         Assuming a quorum is determined to exist at the 2003 Annual Meeting,
because Hercules' by-laws require nominees to receive the affirmative vote of a
majority of the outstanding Shares, abstentions, withhold votes and broker
non-votes, if any, with respect to the election of directors will have the same
effect as voting against the election of directors.

         Required information concerning the necessary vote to ratify the
selection of auditors at the 2003 Annual Meeting and the effects, if any, of
abstentions and broker non-votes on such matter, will be set forth in the
Management Proxy Statement and, in accordance with Rule 14a-5(c) under the
Exchange Act, reference is made to the Management Proxy Statement for such
information.

                   THE COMMITTEE STRONGLY RECOMMENDS THAT YOU
                     VOTE "FOR" THE ELECTION OF ITS NOMINEES

                              ELECTION OF DIRECTORS

         The Committee is soliciting your proxy for the election of its Nominees
as directors of the Company to serve for a three-year term expiring at the 2006
Annual Meeting and until their successors are duly elected and qualified. We are
soliciting proxies in support of the election to the Board of Directors of the
following Nominees and until their respective successors are duly elected and
qualified: Harry Fields, Anthony Kronman, Vincent Tese and Gerald Tsai, Jr.

          In accordance with Hercules Restated Certificate of Incorporation and
by-laws and the Delaware General Corporation Law, the Board of Directors is to
consist of not less than seven and not more than eighteen directors, the exact
number to be specified by the Board of Directors. The directors are to be
divided into three classes as nearly equal in number as possible. At each annual
meeting of shareholders, members of one of the classes, on a rotating basis, are
elected for a three-year term. According to the Management Preliminary Proxy
Statement, thirteen directors currently serve on the Board of Directors, and
four of these directors have terms that expire in 2003, and four directors are
to be elected at the 2003 Annual Meeting. Messrs. Harry Fields, Anthony Kronman,
Vincent Tese and Gerald Tsai, Jr., if elected, would serve for terms expiring at
the 2006 Annual Meeting. Each of the Nominees has consented to serve as a
Nominee, be named in the Committee's proxy soliciting materials as such and
serve as a director of Hercules, if elected.

         If any Nominee is unable to serve or otherwise unavailable to stand for
election as a director at the 2003 Annual Meeting, the Committee intends to
nominate a replacement nominee for election. Should one or more replacement
nominees be required, the named proxies will exercise their discretionary
authority to vote for any replacement nominee selected by the Committee. If any
additional directorships are to be voted upon at the 2003 Annual Meeting, the
Committee reserves the right to nominate additional persons to fill such
positions. The


                                      21




Committee does not expect that the Nominees will be unable to stand for
election but, in the event that any Nominee is unable to do so, Shares
represented by WHITE proxy cards will be voted for the other Nominees and any
replacement nominee. In addition, the Committee reserves the right to nominate
substitute or additional persons if the Company makes or announces any changes
to its by-laws or takes or announces any other action that has, or if
consummated would have, the effect of disqualifying any of the Nominees.

         If the Nominees are elected and take office as directors, they intend
to discharge their duties as directors of the Company in compliance with all
applicable legal requirements, including the fiduciary obligations imposed on
corporate directors under Delaware law.

         If all of the Nominees are elected to the Board of Directors, the
Nominees, together with the minority directors, would constitute a majority of
the thirteen members serving on the Board of Directors and, since the Company's
by-laws provide that action by the Board of Directors requires a majority vote
of the directors present at a meeting at which a quorum is present, the four
Nominees, together with the minority directors, would be able to cause any
action to be taken or not taken by the Board of Directors.

                                  THE NOMINEES

         Set forth below are the names of, and certain biographical information

         Each Nominee, if elected, will be entitled to receive compensation
customarily paid by Hercules to its independent directors, which is described in
the Management Proxy Statement.

         The Committee reserves the right to nominate substitute persons as
Nominees if Hercules makes or announces any changes to the by-laws or takes or
announces any other action that has, or if consummated would have, the effect of
disqualifying any of the Nominees. In addition, if Hercules causes any
additional directorships to be voted upon at the 2003 Annual Meeting, the
Committee reserves the right to nominate additional persons to fill the added
positions. Shares represented by the Committee's WHITE proxy cards will be voted
for any such substitute or additional nominees of the Committee.

                 THE COMMITTEE STRONGLY RECOMMENDS THAT YOU VOTE
                       "FOR" THE ELECTION OF THE NOMINEES

                     CERTAIN EFFECTS OF A CHANGE OF CONTROL

         If all of the Nominees are elected to the Board of Directors, a "Change
of Control" (as such term is defined in the Indenture (the "Indenture") dated as
of November 14, 2000 between the Company and Wells Fargo Bank Minnesota, N.A.,
as Trustee, with respect to the Company's 11 1/8% Senior Notes due 2007 (the
"Notes")) will occur. According to the Company's public filings, as of September
30, 2002 there was $400 million principal amount of the Notes outstanding.
Pursuant to the terms of the Indenture, if a "Change of Control" occurs each
noteholder shall have the right on the Change of Control Payment Date (as such
term is defined in the Indenture which date shall be no earlier than 30 days and
no later than 60 days after notice is mailed to the holders notifying them of a
change of control) to require the Company to repurchase all or any part of that
holder's Notes at a repurchase price equal to 101% of the aggregate principal
amount of Notes repurchased, plus accrued and unpaid interest and liquidated
damages. As of April 15, 2003, the last reported trading price of the Notes
in the over-

                                      23




the-counter market was $110.5 per $100 principal amount of the Notes, a price
in excess of the repurchase price. As a result, the Committee believes it is
unlikely that noteholders will exercise this right.

         The Company has entered into employment agreements with several of its
senior executives. Under these agreements, the election of the Nominees would
constitute a "Change of Control" and therefore in the event that the executive's
employment is terminated during the three-year period following a "Change in
Control" either by the executive with Good Reason or by Hercules other than for
Cause, death or disability (as each such term is defined in the agreements) and,
in certain cases, if the executive terminates his employment with 180 days'
notice for any reason after a "Change in Control", the executive would be
entitled to cash severance equal to three times (two times, in some cases) the
sum of his base salary and the higher of his target annual bonus or the actual
bonus paid or payable in the most recently completed year. The executive would
further be entitled to continued welfare and fringe benefits for three years
(two years, in some cases) following termination of employment. Certain of these
agreements also provide for a cash payment equal to the amount the executive
would have received under Hercules' pension plans (including its supplemental
pension plan) if Hercules had contributed to those plans for an additional three
years. These executives would also be entitled to "gross-up" payments in the
event that any payments or benefits they receive in connection with a change in
control would be subject to "golden parachute" excise taxes imposed under
section 4999 of the Internal Revenue Code of 1986, as amended.

         If the Nominees are elected, it would also constitute a "Change in
Control" under the Company's Nonemployee Director Stock Accumulation Plan. Under
such plan, in the event of a "Change in Control", all outstanding options
immediately vest and become exercisable, unless otherwise directed by the
Hercules Board prior to such "Change in Control". In addition, all exchanged
shares and cash balances of all deferral accounts become immediately vested and
payable.

                    CERTAIN INTERESTS IN THE PROPOSALS AND
                           IN SECURITIES OF HERCULES

         Other than certain compensation as disclosed in the Management Proxy
Statement that is received by the minority directors for their service as
directors of the Company, including certain equity awards, to the knowledge of
the Committee, there are no contracts, arrangements, understandings or
relationships (legal or otherwise) among any member of the Committee or its
associates with respect to any securities of Hercules. Reference is hereby made
to such information which, to the extent it may be deemed required, is
incorporated herein pursuant to Rule 14a-5(c) under the Exchange Act.

         Each Nominee has entered into a letter agreement with ISP. Pursuant to
the letter agreement, each Nominee will receive a fee of $35,000 from ISP for
serving as a nominee which amount is payable when the Committee files with
the Securities and Exchange Commission its definitive proxy statement. This fee
is not refundable or contingent in any manner in connection with the outcome of
the Committee's proxy solicitation or otherwise. The letter agreement also
provides that ISP will indemnify and hold harmless the Nominee from any and all


                                      24



liabilities, losses, claims, damages and out-of-pocket expenses (including
reasonable attorneys' fees and expenses) (collectively, "Losses") based upon
or arising out of the solicitation of proxies from Hercules' shareholders and
the willingness of the Nominee to stand for election as a director of
Hercules, except to the extent that any such Losses (i) may arise out of
inaccurate written information supplied by the Nominee in connection with the
solicitation of proxies or (ii) are found in a final judgment by a court, not
subject to further appeal, to have resulted from bad faith, willful misconduct
or gross negligence on the part of the Nominee.

                        SOLICITATION OF PROXIES; EXPENSES

         The total cost of this proxy solicitation (including fees of attorneys,
proxy solicitors and printing and mailing expenses) will be borne by ISP and is
estimated to be approximately $[________]. Approximately $[________] of such
costs have been incurred to date. The entire expense of the Committee's proxy
solicitation is being borne by ISP. Neither ISP nor the Committee will seek
reimbursement from Hercules for the costs of this proxy solicitation, including
the fees being paid by ISP to the Nominees.

         Proxies may be solicited by mail, telephone, telefax, telegraph,
Internet, e-mail, in person or by similar means. Officers and certain employees
of ISP and its affiliates and the other participants listed on Annex A hereto,
may assist in the solicitation of proxies without any additional remuneration.
Proxies will be solicited from individuals, brokers, banks, bank nominees and
other institutional holders. ISP has requested banks, brokerage houses and other
custodians, nominees and fiduciaries to forward all solicitation materials to

(1)      ISP Investco LLC ("Investco") has the sole power to vote, direct the voting of, dispose of and direct
         the disposition of the Hercules Common Stock. International Specialty Holdings Inc., by virtue of it
         being the sole member of Investco, may be deemed to own beneficially (solely for purposes of Rule
         13d-3) the Hercules Common Stock owned by Investco. International Specialty Products Inc., by virtue
         of its ownership of all of the outstanding common stock of IS Holdings, may be deemed to own
         beneficially (solely for purposes of Rule 13d-3) the Hercules Common Stock owned by Investco. Mr.
         Heyman, by virtue of his beneficial ownership (as defined in Rule 13d-3) of approximately 100% of the
         capital stock of ISP, may be deemed to own beneficially (solely for purposes of Rule 13d-3) the
         Hercules Common Stock owned by Investco.

                                     A-4


(2)      In the ordinary course of its business, Investco purchases securities for its investment portfolio
         with funds obtained from the working capital of Investco, loans from affiliates and borrowings
         pursuant to standard margin arrangements. Because the securities from multiple investments are pooled
         in one account, the amount of margin indebtedness incurred by ISP in connection with its purchases of
         Hercules Common Stock, which purchases were numerous and made over several months, is impossible to
         determine with any degree of certainty.

(3)      Includes with respect to Mr. Heyman 8,498, Mr. Kumar 22,987, Mr. Troubh 16,948 and Mrs. Schaffer
         4,828 shares of the Company's common stock acquired and/or granted to each of them in connection with
         their service as members of the Board of Directors of the Company.

         are exercisable between 11/5/02 and 11/5/11 at an exercise price of $8.52.
