            INTERNATIONAL SPECIALTY PRODUCTS ANNOUNCES ITS INTENTION
                     TO PURCHASE TEN MILLION HERCULES SHARES
                        UPON ELECTION OF THE NOMINEES OF
             THE HERCULES SHAREHOLDERS' COMMITTEE FOR NEW MANAGEMENT
             ------------------------------------------------------

WAYNE, NJ, JULY 14, 2003 - International Specialty Products Inc. (ISP) today
announced that it intends, either directly or through an affiliate, upon the
election of the nominees of The Hercules Shareholders' Committee for NEW
Management, to acquire an additional ten million shares of Hercules Incorporated
(NYSE: HPC) common stock -- over and above its current ownership of 9.9 million
Hercules shares.

ISP intends to commence a tender offer for five million shares at $12 per share
in cash and purchase an additional five million shares of Hercules common stock
through open market purchases thereafter. The tender offer would commence after
the election at Hercules' 2003 Annual Meeting of Shareholders, which is
scheduled for July 25, 2003, of all four Committee nominees and would begin
promptly after certification of the shareholders' vote. The $12 price represents
an almost 50% premium over Hercules' closing price of $8.12 per share on
February 11, 2003 -- the day prior to ISP's filing of an amendment to its
Schedule 13D which indicated that it was considering waging a proxy contest at
Hercules 2003 Annual Meeting. The tender offer would be conditioned on the
Hercules Board eliminating Hercules' "poison pill", which has been one of the
stated intentions of the Committee.

After completion of its tender offer, ISP intends to purchase an additional five
million shares of Hercules common stock in the open market during the following
twelve-month period. These purchases would be made from time to time on the open
market at prevailing market prices or in privately negotiated transactions. ISP,
which has previously satisfied the requirements of the Hart-Scott-Rodino
Antitrust Improvements Act for the purchase of up to 15% of Hercules common
stock, intends to apply for clearance under such Act, promptly following
completion of its tender offer, to purchase up to 20% of Hercules shares. ISP
currently beneficially owns approximately 9% of the outstanding shares of
Hercules common stock and, upon completion of the tender offer and its open
market purchase program, would own 18% of Hercules common stock.

ISP also announced that, together with its Chairman, Samuel J. Heyman, it has
committed to enter into a standstill agreement, which would become effective
upon the election of all four of the Committee's nominees to the Hercules Board.
Pursuant to the standstill agreement, ISP and Mr. Heyman would agree, for a
period of two years, not to make any acquisition or merger proposal for Hercules
or any of its business units, unless a third party makes an




acquisition proposal first, and to otherwise limit their ownership in Hercules'
stock to 20% of Hercules' outstanding shares.

Mr. Heyman stated that "we have made these commitments today following
consultation with several major Hercules shareholders. Our intention to commence
the tender offer and the follow-on open market purchase program, which would
increase our ownership interest in the Company by more than 100%, demonstrates
our commitment to Hercules and is an expression of our confidence in its ability
to grow under the right leadership. The tender offer will also provide those
Hercules shareholders who wish to sell at least a portion of their shares now
with an opportunity to do so at a premium above the current market price."

Mr. Heyman further noted that "we have agreed to enter into the proposed
standstill agreement in order to remove even the slightest remaining appearance
of a conflict of interest, address the stated concerns of several Hercules
shareholders, and broaden the shareholder mandate for our Committee's nominees.
This is in addition to the previously announced procedural safeguards with
respect to any acquisition proposal which we committed to in our June 24th
letter to the Committee."

ISP urges shareholders to sign, date and return the WHITE proxy card voting FOR
The Hercules Shareholders' Committee for NEW Management's director nominees.
Shareholders with questions or in need of assistance in voting their shares
should contact Georgeson Shareholder Communications Inc., the Committee's proxy
solicitation agent, toll free, at (866) 288-2190 (banks and brokerage firms
please call (212) 440-9800).
