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

                                                                   June 30, 2003

Dear Hercules Employee Plan Participant:

         You should  know that we have  received  numerous  calls from  Hercules
employees and retirees who own Hercules stock and have expressed support for our
nominees.  Others have called to ask very  legitimate  questions  with regard to
issues involved in the proxy contest.

         While we have attempted to spell out our strong  disagreement  with the
way in which Joyce has managed the Company, The Hercules Shareholders' Committee
for NEW  Management  believes  that both parties owe you the courtesy of a fully
informative  meeting which would provide you with the  opportunity  to hear from
both  sides.  To this  end,  in a June  16th  letter to  Joyce,  we  proposed  a
discussion  between Joyce and a representative of our Committee,  which would be
open to all Hercules  Employee Plan  participants,  in  Wilmington.  APPARENTLY,
JOYCE  BELIEVES THAT HE IS  ACCOUNTABLE  TO NO ONE - NOT EVEN YOU - BECAUSE,  AT
LEAST AS OF THE DATE OF THIS LETTER, HE HAS NOT RESPONDED.

         While we have all been adversely  affected as Hercules  shareholders by
Joyce's  mismanagement  of the  Company  in our  view,  we know  that you have a
special  interest  in the  outcome  of the proxy  contest  either  as  employees
concerned about the future of your Company and your jobs or as retirees in terms
of your pensions and other benefits.

         ASK YOURSELF: ARE YOU BETTER OFF TODAY THAN YOU WERE WHEN JOYCE CAME TO
THE COMPANY TWO YEARS AGO? In doing so, we ask you to consider what has happened
at Hercules over the last two years:

    o    More than 1,800 employees have lost their jobs.

    o    Many  remaining  employees  have had their  salaries  frozen or capped,
         while Joyce and senior  executives  continue to receive huge  salaries,
         bonuses, stock grants, and golden parachutes.

    o    Hercules has sold one of its best  businesses  in our view at the worst
         possible time - reducing the size of our Company almost in half.

    o    Under  Joyce,  the  Company's  pension  funds  have  been  invested  in
         accordance  with an  inappropriate  and unduly  risky asset  allocation
         policy.  As a result,  the  Company  was  required  last year to take a
         charge to equity of almost $570 million.

    o    Joyce is essentially a caretaker CEO, with no business  strategy and no
         vision, who is unwilling to make investments for the future in terms of
         human resources, R&D, and capital expenditures.




    o    The  Company  under  Joyce  is  in  our  view  in a  virtual  state  of
         stagnation, and employee morale is at an all-time low.

         You  should be aware of Joyce's  history  as a manager,  for he did the
same thing to Union  Carbide that he is now doing to  Hercules.  We believe that
voting for the Board's  nominees  and  allowing  Joyce to remain at Hercules for
another  year is like  renewing  his  driver's  license on the basis of his poor
accident record.  Please help end the long nightmare  Hercules  shareholders and
employees have experienced under Joyce and his predecessors.

         Your vote is all the more important  because of the Company's  director
election Bylaw,  which the majority directors claim requires an affirmative vote
of a majority of ALL OUTSTANDING  SHARES to unseat an incumbent  director.  This
means in effect that A VOTE NOT CAST is the  equivalent  of A VOTE TO PERPETUATE
JOYCE'S TEAM IN OFFICE. Regardless of the number of shares you own, we urge you,
in your own best interest,  to support our shareholder  nominees for election as
Hercules directors. PLEASE SIGN, DATE AND RETURN OUR WHITE PROXY CARD TODAY!

                                   Sincerely,

             THE HERCULES SHAREHOLDERS' COMMITTEE FOR NEW MANAGEMENT
                                                      ---
