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 April 1, 1998, Amendment No. 3 filed on July 24, 1998, Amendment No. 4 filed on August 25, 2000, Amendment No. 5 filed on April 6, 2001, Amendment No. 6 filed on August 21, 2001, Amendment No. 7 filed on March 27, 2002 and Amendment No. 8 filed on July 9, 2002. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. The aggregate transaction consideration described below in Item 4 is expected to be approximately $130 million.

Item 4 is amended and supplemented to include the following information: Going Private Transaction On November 7, 2002, ISP issued the Press Release included as Exhibit E to this Schedule 13D, which is incorporated by reference herein. Mr. Heyman (the "Stockholder") and a Special Committee of the Board of Directors of ISP have reached an agreement on a going private transaction in which the holders of ISP's publicly traded shares would receive $10.30 in cash per share. The agreement followed a determination by the Special Committee that the transaction consideration is fair to ISP's public shareholders. The Special Committee, which consists of ISP directors who are not officers of ISP, has been negotiating with the Stockholder regarding his previously announced proposal of $10 per share. Lehman Brothers Inc. served as financial advisor to the Special Committee. The transaction is expected to proceed as a merger and is subject to the approval by ISP's Board of Directors and execution of a definitive merger agreement. ISP's Board of Directors is expected to meet to consider approval of a definitive merger agreement within the next few days. If the merger agreement is approved by ISP's Board of Directors as anticipated, completion of the merger will be subject to certain closing conditions, including approval by holders of a majority of ISP's shares and approval by holders of a majority of the votes cast by holders of shares not beneficially owned by the Stockholder or the directors or officers of ISP. The Stockholder beneficially owns approximately 80.9% of ISP's outstanding shares of stock. It is anticipated that, upon consummation of the transaction, the ISP common stock would be delisted from trading on the New York Stock Exchange and deregistered with the Securities and Exchange Commission. Other than changes in the capitalization, corporate structure and/or governing documents resulting from the transaction, and other than the intention to cause the Board of Directors of ISP following consummation of the proposed transaction to be comprised solely of the Stockholder and certain members of ISP's Board of Directors who are also members of ISP's management, the Stockholder has no present plans or proposals with respect to any other action referred to in instructions (a) through (j) of Item 4 of the form of Schedule 13D. The Stockholder expressly reserves the right to change its business plans, operations and management arrangements with respect to ISP based on future developments. In addition, the Stockholder reserves the right to make dispositions from time to time prior to the closing of the transaction of shares of common stock owned by Heyman Joint Ventures II LLC (up to 114,336 shares) to the extent permitted by the transaction agreements and applicable law.
