                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     The consolidated financial statements for International Specialty Products
Inc. (the "Company") reflect, in the opinion of management, all adjustments
necessary to present fairly the financial position of the Company at
December 31, 1996 and September 28, 1997, and the results of operations and
cash flows for the periods ended September 29, 1996 and September 28, 1997.
All adjustments are of a normal recurring nature.  These financial statements
should be read in conjunction with the annual financial statements and notes
thereto included in the Company's Annual Report on Form 10-K for the fiscal
year ended December 31, 1996 (the "Form 10-K").

NOTE A:        In February 1997, the Financial Accounting Standards Board
          issued SFAS No. 128, "Earnings per Share", which is required to be
          adopted in 1998.  Implementation of SFAS No. 128, which will require
          the Company to report "Basic Earnings per Share" and "Diluted
          Earnings per Share", will not have a material impact on the earnings
          per share amounts as currently reported by the Company.

NOTE C:        The Company's parent, ISP Holdings Inc. ("ISP Holdings"), was a
          wholly owned subsidiary of GAF Corporation ("GAF") until January 1,
          1997, when its stock was distributed to the stockholders of GAF in a
          series of transactions involving GAF's subsidiaries.  As a result,
          ISP Holdings and the Company are no longer direct or indirect
          subsidiaries of GAF or its subsidiary, G-I Holdings ("G-I Holdings").

NOTE D:   Contingencies

          Asbestos Litigation Against GAF

               GAF is a defendant in a substantial number of pending lawsuits
          involving asbestos-related bodily injury claims.  GAF and G-I
          Holdings have established reserves for such claims based on certain
          assumptions, one of which was the effectiveness of a class action
          settlement of future asbestos-related bodily injury claims (the
          "Settlement").  On June 25, 1997, the United States Supreme Court
          affirmed the ruling of the United States Court of Appeals for the
          Third Circuit that the class in such action was not certifiable, thus
          rendering the Settlement inoperable.  GAF and G-I Holdings have
          advised the Company that they are presently evaluating the effect of
          this Supreme Court decision on the amount of their reserves for
          asbestos-related liabilities, that such analysis could result in GAF
          and G-I Holdings increasing their estimates of asbestos-related
          liabilities and that it is not currently possible to estimate the
          range or amount, if any, of such possible additional reserves.  GAF
          and G-I Holdings have stated that they remain committed to
          effectuating a comprehensive resolution of asbestos-related bodily
          injury claims, that they are presently exploring a number of options,
          both judicial and legislative, to accomplish such resolution, but
          that there can be no assurance that these efforts will be successful.
          
               Neither the Company nor the assets or operations of the Company,
          which was operated as a division of a corporate predecessor of GAF
          prior to July 1986, have been involved in the manufacture or sale of
          asbestos products.  The Company believes that it should have no legal
          responsibility for damages in connection with asbestos-related
          claims.
          
          
          Environmental Litigation
          
               The Company, together with other companies, is a party to a
          variety of administrative proceedings and lawsuits involving
          environmental matters ("Environmental Claims"), in which recovery is
          sought for the cost of cleanup of contaminated sites, a number of
          which Environmental Claims are in the early stages or have been
          dormant for protracted periods.
          
               In the opinion of the Company's management, the resolution of
          the Environmental Claims should not be material to the business,
          liquidity, results of operations, cash flows or financial position of
          the Company.  However, adverse decisions or events, particularly as
          to the liability and the financial responsibility of the Company's
          insurers and of the other parties involved at each site and their
          insurers, could cause the Company to increase its estimate of its
          liability in respect of such matters.  It is not currently possible
          to estimate the amount or range of any additional liability.

          Tax Claim Against GAF
          
               On September 15, 1997, GAF received a notice from the Internal
          Revenue Service (the "Service") of a deficiency in the amount of
          $84.4 million (after taking into account the use of net operating
          losses and foreign tax credits otherwise available for use in later
          years) in connection with the formation in 1990 of Rhone-Poulenc
          Surfactants and Specialties, L.P. (the "surfactants partnership"), a
          partnership in which a subsidiary of GAF, GAF Fiberglass Corporation
          ("GFC"), holds an interest.  The claim of the Service for interest
          and penalties, after taking into account the effect on the use of net
          operating losses and foreign tax credits, could result in GFC
          incurring liabilities significantly in excess of the deferred tax
          liability of $131.4 million that GAF recorded in 1990 in connection
          with this matter.  GAF has advised the Company that it believes that
          GFC will prevail in this matter, although there can be no assurance
          in this regard.  The Company believes that the ultimate disposition
          of this matter will not have a material adverse effect on its
          financial position or results of operations.  GAF, G-I Holdings and
          certain subsidiaries of GAF have agreed to jointly and severally
          indemnify the Company against any tax liability associated with the
          surfactants partnership, which the Company would be severally liable
          for, together with GAF and several subsidiaries of GAF, should GAF
          and certain of its subsidiaries be unable to satisfy such indemnity.

          Item 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

Results of Operations - Third Quarter 1997 Compared With
                        Third Quarter 1996

     The Company recorded third quarter 1997 net income of $22.9 million (24
cents per share) versus $20.1 million (21 cents per share) in the third quarter
of 1996.  The 13.5% increase in net income was attributable to higher operating
and other income and, to a lesser extent, lower interest expense.

     Net sales for the third quarter of 1997 were $183.6 million, a 6% increase
compared with $173.6 million for the third quarter of 1996.  The higher sales
reflected higher sales of specialty chemicals (up $13.6 million) as a result of
increased sales volumes (up $22.8 million), partially offset by the unfavorable
effect of the stronger U.S. dollar relative to other currencies in certain
areas of the world ($6.6 million), and, to a lesser extent, by unfavorable
selling prices.  Partially offsetting the increased sales of specialty
chemicals were lower sales of mineral products and filter products, down $2.2
and $1.3 million, respectively, primarily as a result of lower sales volumes.
The sales growth in the third quarter reflected increased sales in the U.S.,
the Asia-Pacific region and the Western Hemisphere, partially offset by lower
sales in Europe due primarily to the unfavorable effect of the stronger U.S.
dollar.

     Operating income for the third quarter of 1997 increased by 5% to $35.2
million from last year's $33.5 million.  The increase in operating income
reflected improved income from specialty chemicals (up $2.3 million) as a
result of the increased sales, partially offset by the impact of the stronger
U.S. dollar and lower mineral products results (down $0.7 million).

     Interest expense for the third quarter was $6.4 million compared with $7.0
million in the third quarter of 1996, with the decrease due primarily to lower
average borrowings.  Other income, net, for the third quarter of 1997 was $5.4
million compared with $3.0 million in the third quarter of 1996, due
principally to higher investment income.

Results of Operations - Nine Months 1997 Compared With
                        Nine Months 1996

     For the first nine months of 1997, the Company recorded net income of
$71.6 million (74 cents per share), compared with net income of $62.6 million
(64 cents per share) for the first nine months of 1996.  The 14% increase in
net income was attributable to higher operating and other income and lower
interest expense.










                                       7
<PAGE>
     Net sales for the first nine months of 1997 were $572.6 million versus net
sales of $544.1 million for the same period in 1996.  The higher sales were
attributable to increased sales of specialty chemicals (up $28.9 million) as a
result of increased sales volumes (up $54 million), partially offset by the
unfavorable effect of the stronger U.S. dollar relative to other currencies in
certain areas of the world ($16.6 million), and by unfavorable pricing.  The
sales growth reflected sales increases in the U.S., the Asia-Pacific region and
the Western Hemisphere, partially offset by lower sales in Europe due primarily
to the effect of the stronger U.S. dollar.

     Operating income for the first nine months of 1997 was $111.5 million, a
5.5% increase over the $105.7 million recorded in the first nine months of
1996.  The higher operating income reflected improved results in all business
segments, principally specialty chemicals (up $2.5 million due to the higher
sales) and filter products (up $2.1 million primarily due to favorable
pricing), partially offset by the effects of the stronger U.S. dollar in
certain areas of the world.

     Interest expense for the first nine months of 1997 was $19.9 million
compared with $21.9 million for the same period in 1996.  The lower interest
expense was primarily attributable to lower average borrowings.  Other income,
net, for the first nine months of 1997 was $15.9 million compared with $9.5
million last year, with the increase resulting primarily from higher investment
income.


Liquidity and Financial Condition


     During the first nine months of 1997, the Company generated cash from
operations of $79 million, reinvested $45.8 million for capital programs and
generated $17.3 million from net sales of available-for-sale and
held-to-maturity securities, for a net cash inflow of $50.4 million before
financing activities.  Cash from operations reflected a $27 million cash outlay
for net purchases of trading securities and also included $6.3 million of
dividends received from the GAF-Huls Chemie GmbH joint venture.  Working
capital increased by $13.4 million, primarily reflecting a $9.5 million
increase in trade accounts receivable due to higher sales in September 1997
versus December 1996, a $10.1 million increase in accounts receivable, other,
mainly from the sale of the Company's domestic trade accounts receivable, and a
$4.4 million increase in inventories, partially offset by a $14.7 million
increase in accounts payable and accrued liabilities.

     Net cash used in financing activities in the first nine months of 1997
totaled $39.5 million, mainly reflecting a $21.4 million decrease in borrowings
under the Company's bank revolving credit facility, a $5.7 million reduction in
short-term borrowings, a $3.2 million reduction in borrowings from an affiliate
and $10.2 million of repurchases of common stock pursuant to the Company's
repurchase program.

     As a result of the foregoing factors, cash and cash equivalents increased
by $11 million during the first nine months of 1997 to $28.7 million (excluding
$132.7 million of trading, available-for-sale and held-to-maturity securities
and other short-term investments).

     In June and July of 1997, the Company entered into five-year interest rate
swap contracts with a total notional amount of $100 million to convert its
floating interest rates on $100 million of debt to fixed rates.
