             THE HERCULES SHAREHOLDERS' COMMITTEE FOR NEW MANAGEMENT
                       17 State Street, New York, NY 10004

                                                                   June 24, 2003

Fellow Hercules Shareholder:

         Joyce's  June  20th  letter to  shareholders  fails to  respond  to the
literally  hundreds of  well-substantiated  FACTS we have cited in our materials
concerning  his record and conduct at Hercules and Union  Carbide.  Instead,  he
continues to rehash the same "red herring" claims as before:

         (1)      It  is  for  some  reason   inappropriate   for  the  Hercules
                  Shareholders'  Committee for NEW Management to be elected to a
                  majority of the Board seats, without a "control premium," as a
                  result of TWO SEPARATE PROXY  CONTESTS  REFLECTING THE WILL OF
                  THE  MAJORITY  OF THE  COMPANY'S  SHAREHOLDERS,  while  it was
                  perfectly  acceptable  for  Joyce to  acquire  control  of the
                  Hercules Board as a result of his APPOINTMENT to the Board and
                  his subsequent  SELECTION of five  handpicked  directors,  ALL
                  WITHOUT SHAREHOLDER APPROVAL;(1) and

         (2)      The Hercules  Shareholders'  Committee for NEW  Management and
                  Mr. Heyman cannot somehow be trusted because as major Hercules
                  shareholders they have a "conflict of interest" - a contention
                  for which he has never offered the slightest substantiation.

         We do  agree  with  Joyce  on one  matter  - and  that is that the most
critical  question  in this proxy  contest is - WHOM CAN  HERCULES  SHAREHOLDERS
TRUST TO MANAGE THE AFFAIRS OF OUR COMPANY IN YOUR OWN BEST INTERESTS?

         SO THAT YOU CAN MAKE YOUR OWN INFORMED  JUDGMENT,  WE ASK YOU TO REVIEW
THE  FOLLOWING  FACTS,  WHICH JOYCE HAS NEVER  DISCLOSED TO  SHAREHOLDERS  AS IS
CONSISTENT  IN OUR VIEW WITH HIS PRACTICE OF TELLING  SHAREHOLDERS  ONLY WHAT HE
WANTS US TO KNOW. AFTER DOING SO, WE URGE YOU TO MAKE UP YOUR MIND WHETHER JOYCE
HAS ACTED WITH YOUR OWN BEST INTERESTS AT HEART.

         No sooner had he concluded the sale of  BetzDearborn to GE on April 29,
2002 DID JOYCE  UNDERTAKE  AN EFFORT TO ACQUIRE  HERCULES IN A LEVERAGED  BUYOUT
TRANSACTION WITH A FINANCIAL PARTNER. Shortly after the BetzDearborn sale, Joyce
retained,  without the knowledge of the Board,  one of the Company's  investment
bankers  to find a  financial  buyer for  Hercules.  To this end,  Joyce and his
banker  initiated  discussions  with a number of LBO firms,  all of which  firms
typically partner with existing managements.

--------
(1) As Hercules shareholders may recall, Joyce was appointed CEO during the 2002
proxy  contest  only two  weeks  before  the  Annual  Meeting,  in an  effort by
incumbent  directors  we believe to deflect our  criticism  that the Company was
being operated on  "autopilot" by a "caretaker"  CEO. Joyce was the sixth CEO in
six years at Hercules.



         On October 24, 2002,  Joyce  informed the Board for the first time that
several LBO firms had expressed preliminary interest in acquiring the Company in
a management-led buyout. Joyce acknowledged at the same time that the LBO buyers
wanted  management to stay and that he was considering  participating as a buyer
in the LBO.  At the  Company's  next Board  meeting,  on  December  12th,  Joyce
reported that one of the firms had expressed a strong interest in moving forward
with a management-led buyout transaction and conducting due diligence.

         BY WAY OF BACKGROUND,  THROUGHOUT THE PROCESS BEGINNING IN OCTOBER, THE
MINORITY  DIRECTORS  TOOK THE POSITION THAT THEY WOULD  SUPPORT ANY  TRANSACTION
DEEMED ADVANTAGEOUS TO HERCULES  SHAREHOLDERS,  INCLUDING A SALE OF THE COMPANY.
BASED  UPON  THEIR OWN  FINANCIAL  ANALYSIS,  HOWEVER,  THE  MINORITY  DIRECTORS
EXPRESSED A HIGH DEGREE OF  SKEPTICISM  THAT A FINANCIAL  BUYER WOULD BE ABLE TO
JUSTIFY AN ACCEPTABLE  PRICE AND FURTHER  POINTED OUT THE ENORMOUS  DAMAGE BEING
DONE TO THE COMPANY AS A RESULT OF THE 2-1/2 YEAR OLD "SALE PROCESS."

         After  Joyce  reported  at the  December  12th  Board  meeting  that he
believed  there to be a 75% chance that a transaction  would  materialize  at an
attractive price for Hercules shareholders, the Board unanimously authorized the
due  diligence  process  requested  by the LBO firm.  While the LBO firm made it
clear that it required management continuity,  Joyce continued to insist that he
had had no discussions with the buyer with regard to his own role. Joyce further
argued that, since his participation in the  management-led  buyout had not been
specifically discussed, he should continue to be involved in the ongoing process
representing the interests of the Company.

         In view of the virtual  certainty that he would be participating in any
ultimate  transaction  as a buyer and after the minority  directors  objected to
Joyce's  "sitting  on both sides of the table," on  February  21st,  the outside
Board  members,  excluding  Joyce,  assumed  responsibility  for  overseeing the
process. SEVERAL WEEKS LATER, AFTER THREE MONTHS OF INTENSIVE DUE DILIGENCE, THE
LBO FIRM MADE A "TAKEUNDER"  PROPOSAL TO ACQUIRE THE COMPANY FOR $9 PER SHARE IN
A LEVERAGED BUYOUT TRANSACTION TO BE LED BY JOYCE AND OTHER UNSPECIFIED  MEMBERS
OF SENIOR  MANAGEMENT.  THE PROPOSAL WAS MADE SUBJECT TO FURTHER DUE  DILIGENCE,
WITH PROVISIONS FOR THE COMPANY'S  REIMBURSEMENT  OF THE BUYERS'  EXPENSES AND A
"BREAK-UP"  FEE OF $60 MILLION.  FORTUNATELY,  EVEN FOR THE MAJORITY  DIRECTORS,
THIS WAS A  "BRIDGE  TOO  FAR,"  AND  THEY  JOINED  OUR  MINORITY  DIRECTORS  IN
UNANIMOUSLY REJECTING THE PROPOSAL ON MARCH 14TH.

         You should  know that,  without the sale of  BetzDearborn,  a leveraged
buyout  transaction could not have been even contemplated in our view because of
the amount of equity  which would have been  required for such a  transaction  -
raising  serious  question  we  believe  as to  the  motivation  behind  JOYCE'S
SINGLE-MINDED EFFORT TO ENGINEER THE BETZDEARBORN SALE.

         While on the subject of the  BetzDearborn  sale, if there was any doubt
as to the  extraordinary  mistake that Joyce and the majority  directors made in
selling that business,  it

                                       2


was  eliminated  when,  at a GE investor  conference  last week (June 20) on the
subject  of  the  Company's  "new  growth  platforms,"   leading  GE  executives
reaffirmed  how well  they  were  doing  with  BetzDearborn.  For they  informed
investors at the conference that operating profits for BetzDearborn for the last
eight months of 2002 under GE's  ownership  had been up 20% over the same period
in the prior year,  and that they are  currently  projecting  a further  15%-20%
year-over-year  increase in 2003.  Assuming the low end of this projection,  had
Hercules retained  BetzDearborn,  we estimate that Hercules'  earnings this year
would  have been an  estimated  $1.39 per share,  more than 90% higher  than the
current Wall Street  consensus  estimate  for Hercules of $0.72 per share.  A GE
executive  further observed that one of the reasons for the dramatic  turnaround
was that GE had made the requisite  commitment -- which Joyce apparently had not
-- to the business in terms of investing in growth, technology, and people.

         KNOWING WHAT YOU NOW KNOW ABOUT HIS ROLE IN THE PROPOSED "TAKEUNDER" OF
OUR  COMPANY  AT A PRICE OF $9 PER SHARE,  WHAT DO YOU THINK  ABOUT  JOYCE,  HIS
CONTINUED  PURSUIT OF HIS OWN  SELF-INTEREST,  AND  WHETHER HE CAN BE TRUSTED TO
REPRESENT THE INTERESTS OF HERCULES SHAREHOLDERS?

         When Joyce  packed the  Hercules  Board with his  handpicked  directors
without seeking shareholder approval - WAS HE ACTING IN HIS INTERESTS OR YOURS?

         When Joyce engineered the BetzDearborn sale without seeking shareholder
approval - WAS HE ACTING IN HIS INTERESTS OR YOURS?

         When Joyce refused to consider a voluntary cut in his  compensation  to
match the financial  sacrifices asked of thousands of other Hercules  employees,
including  even the  Company's  directors  for a short  period  of time - WAS HE
ACTING IN HIS INTERESTS OR YOURS?

         When Joyce  opposed the effort of the minority  directors  last year to
redeem,  or relax the  provisions  of,  the  poison  pill  unless  the  minority
directors  agreed to endorse his re-election to the Board - WAS HE ACTING IN HIS
INTERESTS OR YOURS?

         When  Joyce,  with  the  assistance  of his  "enablers,"  the  majority
directors, gave himself two golden parachute agreements, outlandish bonuses, and
other  compensation  which would  entitle him, had he completed the $9 per share
LBO or should he be repudiated in this proxy contest,  to almost $30 million for
his two years on the job - WAS HE ACTING IN HIS INTERESTS OR YOURS?

         When Joyce attempted with a financial  partner to take over the Company
from  its  shareholders  at a  price  of $9 per  share  - WAS HE  ACTING  IN HIS
INTERESTS OR YOURS?

         FINALLY,  ASK  YOURSELF:  WHAT IS IT ABOUT  JOYCE,  HIS  ACTIONS OR HIS
RECORD THAT WOULD  WARRANT YOUR WANTING TO ENTRUST THE AFFAIRS OF THE COMPANY TO
HIM?

         As major Hercules shareholders, the interests of our Committee members,
as well as Mr. Heyman and his affiliates,  are fully aligned with yours,  and we
would never

                                       3


countenance  conduct  similar to that of Joyce.  IN ORDER TO LAY TO REST FOR ALL
TIME JOYCE'S "RED HERRING" CLAIMS AND TO AVOID THE SLIGHTEST POSSIBILITY OR EVEN
APPEARANCE  OF A CONFLICT OF INTEREST,  WE HAVE  RECEIVED A COMMITMENT  FROM MR.
HEYMAN AND HIS AFFILIATES, AS SHOWN ON THE FOLLOWING PAGE, THAT THE INTERESTS OF
HERCULES SHAREHOLDERS WILL BE SAFEGUARDED WITH RESPECT TO ANY CORPORATE TAKEOVER
TRANSACTION.

         While  it  should  be  underscored  that  neither  Mr.  Heyman  nor his
affiliates  intend  to  acquire  Hercules,  this  commitment  provides  concrete
assurance  that  under new  management  there  will not be a repeat  of  Joyce's
outrageous  self-dealing.  If  elected,  the  Committee  members  pledge to have
Hercules promptly enter into an agreement with Mr. Heyman and his affiliates, as
outlined in the commitment letter.

         IN YOUR  OWN BEST  INTEREST,  WE URGE YOU TO  SUPPORT  THE  COMMITTEE'S
NOMINEES FOR ELECTION AS HERCULES  DIRECTORS.  PLEASE SIGN,  DATE AND RETURN OUR
WHITE PROXY CARD TODAY!


                                   Sincerely,

To The Hercules Shareholders' Committee for NEW Management
17 State Street
New York, NY  10004


         While we have no intention of making a proposal to acquire Hercules, in
order to avoid any  possible  conflict of interest or even the  appearance  of a
possible  conflict,  the undersigned and our respective  affiliates (the "Heyman
parties"),  hereby agree,  subject to the Committee's  nominees being elected to
Hercules' Board of Directors,  to support and abide by the following  procedural
safeguards  in  connection  with any future  acquisition  proposal  made for the
Company.

         o    In the event that any acquisition proposal is made for Hercules by
              the Heyman parties:

              o   The Heyman  parties  would  support the formation of a Special
                  Committee  to respond to and, if  appropriate,  negotiate  any
                  acquisition  proposal.  The Special Committee would consist of
                  solely independent and disinterested directors, represented by
                  independent financial advisors and legal counsel.

              o   The Heyman parties would not pursue any  acquisition  proposal
                  for Hercules that is not recommended by the Special Committee.

              o   The Heyman  parties  would only  proceed  with an  acquisition
                  transaction  for  Hercules if approved  by  two-thirds  of the
                  shares (excluding those shares owned by the Heyman parties).

              o   The Heyman  parties  would  support a competing  proposal by a
                  third party if the Special  Committee  decides the third party
                  proposal is superior.

         o    In the  event a third  party  makes an  acquisition  proposal  for
              Hercules and the Heyman parties have not:

              o   The Heyman parties would tender all shares  beneficially owned
                  by them  into any  tender  or  exchange  offer,  if  Hercules'
                  disinterested   and  independent   directors   recommend  that
                  shareholders accept such offer; and


                                      A-1




              o   If any vote of  Hercules  shareholders  is held in  connection
                  with a third party  acquisition  proposal,  the Heyman parties
                  would vote all shares  beneficially  owned by them in the same
                  proportion as the votes of the other Hercules shareholders.



                                   Sincerely,


International Specialty Products Inc.
