Fellow Hercules Shareholders:

         Dr. Joyce and  the Hercules Board have refused as of this date to set a
record date for, and schedule,  the Annual Meeting.  In view of this fact, while
the  Committee's  Proxy  Statement  has been  completed,  the  Committee  is not
currently in a position to solicit your proxy. We are  nevertheless  enclosing a
copy which we thought you might wish to see at an early time.

         Should  you  have  any  questions,  please  call  Georgeson Shareholder
Communications, Inc., our proxy solicitation agent, toll-free at 1-866-288-2190.
