There can be little doubt that the refinancing option was available to the Company, and I trust that the information we forwarded has been helpful to you. On another issue, in what one would ordinarily assume to be a simple matter of fact, Hercules senior management has apparently advised ISS, if I understood the point correctly, that the Company has a very productive R&D effort and that 18% of its current sales are from new products introduced in the last five years. Contrary to that assertion, the Company's R&D effort is substantially below the specialty chemical industry average, and we are simply not generating anywhere near that amount of sales from "new products," as that term is commonly used in industry. This is further evidenced by the low rate of sales growth at the Company for 2002 (about 50% of the industry average). While these two isolated issues may not drive your decision, I write to you about them because they raise a more fundamental question - to what extent can ISS, any other impartial rating agency, or arbiter in a contested matter rely on the unsubstantiated assertions of a party whose claims in connection with a whole host of matters have to be regarded as suspect? In this connection, despite the fact that we have called to the attention of Hercules shareholders the many misleading and factually incorrect statements coming from management, the Company has made little effort - nor could it - to rebut our contentions. You should know that we have accepted the offer of Hercules' largest shareholder, Mario Gabelli, to debate/discuss any of the issues with Bill Joyce before institutional shareholders. We have also challenged Joyce to a debate/discussion before Hercules employees and retirees in Wilmington to address unfounded management assertions which could vitally affect Hercules employees and retirees. To date, Joyce has not responded to either invitation. In this regard should ISS also so desire, we would be more than willing to be part of any meeting with ISS, Joyce and representatives of our Committee face-to-face to address any other issues of concern or in conflict in connection with your process. Sincerely, /s/SAMUEL J. HEYMAN ---------------------- Samuel J. Heyman SJH:kjc
