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

                                                                    July 8, 2003

Dear Hercules Employee/Retiree:

         Joyce's  July 1st  letter is filled  with  assertions  that are  either
false, misleading, or have no bearing on the proxy contest.

         First,  THE  COMMITTEE  IS NOT  ATTACKING  HERCULES  EMPLOYEES OR THEIR
ACCOMPLISHMENTS  BUT  RATHER  JOYCE AND HIS  ASSOCIATES  ON THE  BOARD.  We have
nothing but the greatest respect for Hercules employees, the vast number of whom
are  hard-working,  capable,  and loyal and who have been forced to "soldier on"
over  the  last  several  years  under  two  caretaker  CEO's  -  Joyce  and his
predecessor.

         Second,  you should  know that  there has never  been an issue  between
Joyce and our minority  directors  concerning  employee benefits and pensions at
Hercules. In our June 2nd letter to shareholders, we clearly stated our position
as follows:

         "WITH REGARD TO BENEFIT  PROGRAMS,  THE DIRECTORS ARE IN AGREEMENT THAT
         THE COMPANY'S PENSION  OBLIGATIONS TO RETIREES AND PENSION BENEFITS FOR
         ACTIVES MUST BE PRESERVED AND SAFEGUARDED. THE COMPANY'S DIRECTORS HAVE
         UNANIMOUSLY  APPROVED,  HOWEVER,  COST REDUCTIONS IN HEALTH AND MEDICAL
         PROGRAMS IN KEEPING WITH WHAT HUNDREDS OF OTHER  COMPANIES IN CORPORATE
         AMERICA HAVE ALREADY DONE" (P.19).

While we are frank to state that we did subscribe to management's  position with
respect to medical cost  benefits,  the  minority  directors  have  consistently
supported the  safeguarding of all pensions.  With regard to the former,  we are
not any happier than Joyce about the necessity  for recent  increases in medical
costs to employees  and retirees - but  unfortunately  this has become a fact of
life in corporate America.

         THIRD,  JOYCE'S  REFERENCES  TO ISP ARE  IRRELEVANT.  FOR OUR  MINORITY
DIRECTORS  AND  NOMINEES,  MOST  ALL  OF  WHOM  HAVE  NO  ASSOCIATION  WITH  ISP
WHATSOEVER,  HAVE NO PLAN TO IMPOSE  ISP'S  COMPENSATION  STRUCTURE  ON HERCULES
EMPLOYEES/RETIREES.  Parenthetically,  assuming  that there was any relevance to
the  point,  if one  were to  compare  the two  compensation  programs  in their
entirety, ISP's total compensation and benefits are more than comparable to that
of  Hercules.  For ISP has a generous  401(k) plan in  addition  to  substantial
equity  incentives  for the vast  majority of its  employees.  THE FACT THAT ISP
TAKES  VERY GOOD CARE OF ITS  EMPLOYEES  IS  DEMONSTRATED  BY ITS HIGH  EMPLOYEE
MORALE AND A  VOLUNTARY  TURNOVER  RATE  WHICH IS LESS THAN 1/3 OF THE  NATIONAL
AVERAGE FOR THE U.S. MANUFACTURING INDUSTRY.

         Fourth,  Joyce's contention that the Company is VOLUNTARILY making cash
contributions to shore up its pension plans is PURE NONSENSE. For the Company is
being




FORCED to make these  contributions  to maintain  compliance  with ERISA funding
requirements resulting from Joyce's mismanagement of the plans, which has caused
the Company to take a charge to equity last year of almost $570  million.  Under
the Joyce theory, we suppose,  the more money he loses in the pension plans, the
more money the Company is required to  contribute  to the plans,  and the better
off employees and retirees will be! ASK YOURSELF:  IS JOYCE'S ARGUMENT AN INSULT
TO THE INTELLIGENCE OF HERCULES EMPLOYEES AND RETIREES OR WHAT?

         Finally,  the single  most  critical  issue in this proxy  contest is -
WHETHER HERCULES SHAREHOLDERS, EMPLOYEES, AND RETIREES CAN AFFORD TO CONTINUE TO
ENTRUST  THEIR  INVESTMENTS  AND  FUTURES  TO JOYCE  AND HIS  ASSOCIATES  ON THE
COMPANY'S  BOARD.  IF YOU  BELIEVE,  AS WE DO,  THAT IT IS TIME FOR A CHANGE  AT
HERCULES AND WHAT WE NEED IS A DYNAMIC,  "HANDS-ON"  CHIEF  EXECUTIVE  WHO HAS A
VISION FOR OUR COMPANY AND A LONG TERM STRATEGY FOR ITS  BUSINESSES,  LEADERSHIP
QUALITIES,  AND AN INTEREST IN  ENHANCING  SHAREHOLDER  VALUES FOR ALL  HERCULES
SHAREHOLDERS, WE URGE YOU TO SIGN, DATE AND RETURN OUR WHITE PROXY CARD TODAY!

                                   Sincerely,


             THE HERCULES SHAREHOLDERS' COMMITTEE FOR NEW MANAGEMENT
                                                      ---
