This Amendment No. 4 ("Amendment No. 4") amends the
Statement on Schedule 13D (the "Schedule 13D") originally filed on July 3, 1991
by Samuel J. Heyman, GAF Corporation, G-I Holdings Inc., G Industries Corp. and
GAF Fiberglass Corporation (formerly known as GAF Chemicals Corporation), as
amended by Amendment No. 1 filed on January 9, 1997, Amendment No. 2 filed on

stock, par value $.01 per share (the "Common Stock"), of International Specialty
Products Inc., a Delaware corporation (the "Company"). Capitalized terms used
herein and not defined herein have the meanings ascribed thereto in the Schedule
13D, as amended. This Amendment No. 4 is being filed to report a change in the
beneficial ownership of Common Stock by the Reporting Persons resulting solely
from a reduction in the number of outstanding shares of Common Stock.

the Reporting Persons may be deemed to own beneficially (as that term is defined
in Rule 13d-3 of the Securities Exchange Act of 1934, as amended), in the
aggregate, 52,567,240 shares of Common Stock (of which 239,200 represent shares
underlying options awarded to Mr. Heyman under the Company's stock option plan
that are exercisable within 60 days of the filing of this Amendment No. 4),
representing approximately 77.0% of the Common Stock outstanding on August 25,
