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


                                                                   July 14, 2003

Fellow Hercules Shareholders:

         While  we  have  been  sharply  critical  of  Joyce  and  his  majority
directors,  we remain convinced that there are still strong underlying values at
Hercules and that the Company's two remaining,  primary businesses,  Aqualon and
Pulp and  Paper,  under the right  direction,  have  substantial  potential  for
growth. As a further  expression of its confidence in the future of the Company,
ISP is  announcing  today its  intention  to purchase an  additional  10 million
shares of Hercules  common stock -- over and above our current  ownership of 9.9
million  Hercules  shares --  conditioned  upon the election of the  Committee's
nominees.

         ISP  intends to  commence  a tender  offer for five  million  shares of
Hercules  at $12 per share in cash and to purchase an  additional  five  million
shares of Hercules common stock through open market purchases thereafter.  ISP's
tender offer will commence promptly after final certification of the election of
the Committee's four nominees and will be conditioned on the Board's elimination
of the poison  pill,  which will be one of the first  actions  taken  should our
nominees be elected to the Board. 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 indicating that it was
considering waging a proxy contest at the Company's 2003 Annual Meeting.

         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. The completion of the tender offer and
the open market purchase  program would increase ISP's holdings in Hercules from
9.9 million shares to 19.9 million shares (or 18% of the outstanding  shares), a
more than 100% increase in ISP's current interest in Hercules.

         Not only does ISP's commitment demonstrate its confidence in the future
of Hercules  under NEW  management,  but it further  aligns the interests of our
Committee members with those of Hercules shareholders, INCREASING OUR INVESTMENT
TO APPROXIMATELY  $250 MILLION AS A RESULT OF ISP'S TENDER OFFER AND OPEN MARKET
PURCHASE PROGRAM.

         COMPARE THIS WITH THE FACT THAT JOYCE HAS NOT  PURCHASED A SINGLE SHARE
IN HERCULES AND ASK YOURSELF:  WHO BETTER  REPRESENTS  THE INTERESTS OF HERCULES
SHAREHOLDERS - THE COMMITTEE,  INCLUDING OUR NOMINEES,  AN OUTSTANDING  GROUP OF
EXPERIENCED  BUSINESS PEOPLE AND PROFESSIONALS,  WITH AN AGGREGATE INVESTMENT IN
HERCULES OF $250 MILLION, WHO ARE COMMITTED TO ENHANCING VALUES FOR ALL HERCULES



SHAREHOLDERS  AS WE HAVE  INVESTED  OUR OWN MONEY IN  HERCULES  AS YOU HAVE,  OR
JOYCE,  WHO HAS NOT  PURCHASED  A SINGLE  SHARE OF  HERCULES  STOCK  AND IS MORE
INTERESTED IN POSITIONS, PARACHUTES AND PERKS?

         On another subject,  several Hercules  shareholders  have expressed the
view that they would like to see  further  assurances  designed  to prevent  the
possibility  of a  conflict  of  interest  between  Hercules  and  ISP  and  its
affiliates,  including Mr. Heyman.  As you may recall from our June 24th letter,
in order to avoid a repeat of Joyce's outrageous self-dealing in connection with
his $9 per share LBO offer,  ISP and Mr.  Heyman  provided a written  commitment
effectively  safeguarding the interests of Hercules shareholders with respect to
any corporate  transaction involving Hercules and ISP, by requiring a two-thirds
vote of Hercules shareholders EXCLUDING the shares of ISP and its affiliates.(1)

         In order  to  remove  even  the  slightest  remaining  appearance  of a
conflict  of   interest,   address  the  stated   concerns  of  these   Hercules
shareholders,  and broaden the shareholder mandate for our Committee's nominees,
the Committee has obtained a further  commitment  from ISP and its affiliates to
enter into a standstill agreement (attached as an exhibit to this letter), which
would become  effective  upon the election of our four  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 the Company's outstanding shares.

         In yet  another  transparent  election  ploy,  Hercules  late last week
released "earnings guidance" for the second quarter. While the "headline" number
was an estimated 27-29(cent) per share for the quarter, a review of management's
eleventh-hour,  "smoke  and  mirrors"  release  serves  as  an  example  of  how
misleading  management's  earnings reports have really been under Joyce over the
last two years.

o        The  estimate  includes  INCOME of 2(cent) per share for  "Discontinued
         operations," 1(cent) per share for a reversal of "Restructuring costs,"
         and  6(cent)  per share for "Tax  benefit  attributable  to donation of
         intellectual  property"  - FOR A TOTAL OF 9(CENT) PER SHARE OF ONE-TIME
         INCOME ITEMS.

o        With respect to income from ongoing operations,  management  forecasted
         21-23(cent)  per share  which,  based upon the  experience  of our four
         minority directors with management estimates,  MEANS 21(CENT) PER SHARE
         - a 1(cent) increase over the 20(cent) per share reported in the second
         quarter of 2002. WHAT MANAGEMENT HAS FAILED TO


---------------
(1) Contrary to the recent report from Institutional Shareholder Services, these
assurances go well beyond Delaware law and the Company's charter and Bylaws.


                                        2


         DISCLOSE, HOWEVER, IS THAT ALMOST 2 1/2(CENT) PER SHARE OF THE 21(CENT)
         CAME  FROM A  ONE-TIME  INSURANCE  BENEFIT,  AND OF  THE  REMAINING  18
         1/2(CENT)  PER  SHARE,  AT  LEAST  5(CENT)  PER  SHARE WE  ESTIMATE  IS
         ATTRIBUTABLE TO THE IMPACT OF THE LOWER U.S.  DOLLAR.  PUT ANOTHER WAY,
         WITHOUT THE BENEFIT OF THE ONE-TIME  INSURANCE  ITEM AND THE  FAVORABLE
         CURRENCY IMPACT,  INCOME FROM ONGOING OPERATIONS FOR THE SECOND QUARTER
         WOULD HAVE BEEN SHARPLY LOWER THAN THE SAME QUARTER LAST YEAR.

o        Although  reported sales for the Company were projected to be 8% higher
         than the  second  quarter  last  year,  we  estimate  that 6% of the 8%
         resulted from the lower U.S. dollar.

         ASK YOURSELF:

         DOESN'T THIS LATEST EARNINGS  ESTIMATE  ILLUSTRATE THE LACK OF ANY REAL
PROGRESS WITH RESPECT TO THE OPERATING  PERFORMANCE OF THE COMPANY'S  BUSINESSES
UNDER JOYCE?

                                       AND

         ISN'T  JOYCE'S  PENCHANT  FOR  "PRO  FORMA"  EARNINGS,  "NON-RECURRING"
CHARGES, AND "ONE-TIME INCOME ITEMS" RELATED TO HIS REFUSAL FOR ALMOST TWO YEARS
NOW TO HIRE A CHIEF FINANCIAL OFFICER FOR THE COMPANY?

         It is now clear why Joyce pushed his  associates on the Hercules  Board
to  authorize  restricted  stock  grants in the amount of more than one  million
shares to himself and other  executives just prior to the June 6 record date. In
addition to the obvious economic benefit of stock GRANTS rather than OPTIONS, to
add  insult  to  injury,  Joyce is now  claiming  the right to have most all the
shares covered by these unvested, restricted grants voted in the proxy contest.

         WHAT DO YOU  THINK  OF A CHIEF  EXECUTIVE  WHO IS  WILLING  NOT ONLY TO
MISLEAD  SHAREHOLDERS  ABOUT THE PERFORMANCE OF THE COMPANY UNDER HIS MANAGEMENT
BUT TO RESORT TO  "STUFFING  OF THE  BALLOT  BOX" IN AN  ATTEMPT  TO  PERPETUATE
HIMSELF IN OFFICE?

          *     *     *     *     *     *     *     *     *     *     *

         The  Hercules  stock  price,   between  the  time  Joyce  became  Chief
Executive,   on  May  8th,  2001  and  the  closing  price  on  July  11th,  has
underperformed  the S&P MidCap  Specialty  Chemicals  Index by almost  30%.  The
Company's RECENT stock price  performance,  however,  measured from 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  for control of the
Hercules Board,  to the close on July 11th, has outpaced,  for the first time in
Joyce's tenure,  the S&P MidCap Specialty  Chemicals Index by approximately 19%.
The improvement of Hercules' stock price performance has come



                                        3



only  in the  wake  of the  Committee's  proxy  campaign,  the  prospect  of new
management and a new direction for the Company,  and the  Committee's  expressed
determination to enhance shareholder values.

         WE ASK YOU TO JUDGE FOR  YOURSELF  WHETHER  THE PRICE OF YOUR  STOCK IS
LIKELY TO BE HIGHER OR LOWER AS A RESULT OF A CHANGE IN  LEADERSHIP AT HERCULES.
PLEASE SIGN, DATE, AND RETURN OUR WHITE PROXY CARD TODAY!

To The Hercules Shareholders' Committee for NEW Management
17 State Street
New York, NY  10004


            While the  undersigned  and our respective  affiliates  (the "Heyman
parties") have no intention of making a proposal to acquire Hercules,  we hereby
agree,  subject to all of the  Committee's  nominees  being elected to Hercules'
Board of Directors, to enter into a standstill agreement with Hercules that will
contain the following terms:

     1.   The  Heyman  parties  will  agree  that for a period of two years (the
          "Term")  they will not  acquire  or agree,  offer,  seek or propose to
          acquire the  Company or  substantially  all of its assets,  by merger,
          tender or  exchange  offer or  consolidation  or to make a proposal to
          acquire any of Hercules' business units or to otherwise enter into any
          other  business  combination  transaction  (in each case,  a "Takeover
          Proposal").

     2.   Notwithstanding  anything  contained  above,  in the event  that (x) a
          third party  proposes to enter into an agreement  with Hercules or any
          of its subsidiaries  with respect to a merger,  consolidation or other
          business  combination  involving  Hercules or any of its subsidiaries,
          (y) a bona fide tender offer or exchange offer is announced by a third
          party which would result, if consummated in accordance with its terms,
          in a change of control of Hercules  or (z) a third  party  proposes to
          enter  into an  agreement  with  Hercules  with  respect  to the sale,
          transfer,  conveyance or other  disposition,  in one  transaction or a
          series of related transactions, of a material portion of the assets of
          Hercules and its subsidiaries taken as a whole or of any business unit
          of Hercules (in each case, an "Acquisition Proposal"), then the Heyman
          parties will be entitled to make a Takeover  Proposal if such Takeover
          Proposal  is a Superior  Proposal  (as defined  below).  Additionally,
          notwithstanding anything contained above, in the event the third party
          Acquisition  Proposal is for assets of Hercules  and its  subsidiaries
          not  constituting all or  substantially  all of such assets,  then the
          Heyman  parties'  Takeover  Proposal,  if any,  shall  not be for more
          assets than those subject to such third party's Acquisition Proposal.


                                       A-1



          As used in this paragraph (2),  "Superior  Proposal" means a bona fide
          written  proposal that is on terms that would, if consummated,  result
          in a transaction that would, or would be reasonably likely to, be more
          favorable  to  Hercules  or its  shareholders  than  the  transactions
          contemplated by the Acquisition Proposal.

     3.   In the event the Heyman  parties  make a permitted  Takeover  Proposal
          pursuant to paragraph  (2) above or after the  expiration of the Term,
          Samuel J. Heyman and Sunil  Kumar  agree to resign  from the  Hercules
          Board upon making such a Takeover Proposal.

     4.   The Heyman parties will agree that,  except as expressly  permitted in
          paragraph  (2) above,  during the Term they will not acquire or agree,
          offer,  seek or propose to acquire more than twenty  percent  (20%) of
          the then outstanding shares of Hercules common stock.

     5.   The  commitments  referred to in  paragraphs  (1),  (2) and (3) are in
          addition  to the  procedural  safeguards  set  forth in the June  24th
          letter from the Heyman  parties to the  Committee,  which  continue in
          full force and effect.



                                   Sincerely,


International Specialty Products Inc.
