                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     The consolidated financial statements for International Specialty
Products Inc. (the "Company"), formerly ISP Holdings Inc. ("ISP Holdings")
reflect, in the opinion of management, all adjustments necessary to present
fairly the financial position of the Company at June 28, 1998, and the
results of operations and cash flows for the periods ended June 29, 1997
and June 28, 1998.  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 ISP Holdings' Annual
Report on Form 10-K for the fiscal year ended December 31, 1997 (the "Form
10-K").


Note 1.  Merger of International Specialty Products Inc. into ISP Holdings
         Inc.

     On July 15, 1998, International Specialty Products Inc. ("Old ISP")
merged (the "Merger") with and into ISP Holdings.  In connection with the
Merger, ISP Holdings changed its name to International Specialty Products
Inc.  In the Merger, each outstanding share of Old ISP's common stock,
other than those held by ISP Holdings, was converted into one share of
common stock of the Company, and the outstanding shares of ISP Holdings
were converted into an aggregate of 53,833,333 shares (or approximately
78%) of the outstanding shares of common stock of the Company.


Note 2.  Acquisitions

     Effective April 1, 1998, the Company acquired the remaining 50% interest
in its joint venture with Huls AG, GAF-Huls Chemie GmbH ("GhC").  GhC consists
of a manufacturing facility that produces primarily butanediol and
tetrahydrofuran.  As part of the transaction, the Company also acquired Huls'
production facility that supplies GhC with its primary raw material, acetylene.
The results of GhC are included in the Company's financial statements on a
consolidated basis from the date of acquisition, including sales of $20.0
million and operating income of $6.7 million for the second quarter of 1998.

     In February 1998, the Company acquired Polaroid Corporation's Freetown,
Massachusetts fine chemicals facility.  In connection with the acquisition, the
Company entered into a sale-leaseback arrangement of the facility's equipment
with a third party.  The lease has been accounted for as an operating lease,
with an initial term of four years and, at the Company's option, up to three
one-year renewal periods.  As part of the transaction, the Company entered into
a long-term supply and license agreement with Polaroid for the imaging
chemicals and polymers manufactured at the facility and used by Polaroid in its
instant film business.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


Note 6.  Contingencies

Environmental Litigation

     The Company, together with other companies, is a party to a variety of
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.

     For further information regarding environmental matters, reference is made
to Note 13 to Consolidated Financial Statements contained in the Form 10-K.


Tax Claim against GAF

     Certain subsidiaries of the Company were members of the GAF Corporation
("GAF") consolidated Federal income tax group (the "GAF Group") in 1990 and,
accordingly, would be severally liable for any tax liability of the GAF Group
in respect of such year.  Effective as of January 1, 1997, neither the Company
nor any of its subsidiaries are members of the GAF Group.

     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 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 GFC be unable to satisfy such liability.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


Note 7.  New Accounting Standard

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities."  SFAS No. 133 establishes accounting and
reporting standards requiring that every derivative instrument be recorded in
the balance sheet as either an asset or liability measured at its fair value.
SFAS No. 133 requires that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met.
Special accounting for qualifying hedges allows a derivative's gains and losses
to offset related results on the hedged item in the income statement.

     SFAS No. 133 is effective for fiscal years beginning after June 15, 1999,
but may be adopted earlier.  The Company has not yet determined the effect of
adoption of SFAS No. 133 and has not determined the timing or method of
adoption of the statement.  Adoption of SFAS No. 133 could increase volatility
in earnings and other comprehensive income.


Note 8.  Long-term Debt

     The Company intends to refinance its $200 million 9% Senior Notes due
March 1999; accordingly, such notes are classified as long-term debt on the
Consolidated Balance Sheet.

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

Results of Operations - Second Quarter 1998 Compared With
                        Second Quarter 1997

     The Company recorded second quarter 1998 net income of $19.0 million
(35 cents diluted earnings per share) versus $14.5 million (27 cents
diluted earnings per share) in the second quarter of 1997.  The 31%
increase in net income was attributable to higher operating and other
income.

      Net sales for the second quarter of 1998 were $219.8 million, an 11%
increase compared with $197.8 million for the second quarter of 1997.  The
increase in sales was primarily attributable to the GhC acquisition (see
Note 2 to Consolidated Financial Statements), which accounted for $20.0
million of the sales increase, and also reflected a $2.1 million (9%)
increase in sales of mineral products due to increased sales volumes,
partially offset by the unfavorable effect of the stronger U.S. dollar
relative to other currencies in certain areas of the world ($3.6 million).
Sales of filter products decreased slightly for the quarter.  The sales
growth in the second quarter resulted from higher sales of specialty
chemicals and mineral products in the U.S. and higher sales of specialty
chemicals in the Western Hemisphere, partially offset by lower sales in the
Asia-Pacific region and Europe (excluding GhC) reflecting the unfavorable
effect of the stronger U.S. dollar.

     Operating income for the second quarter of 1998 was $48.1 million
compared with last year's $39.0 million.  The 23% increase in operating
income primarily resulted from the GhC acquisition, which accounted for
$6.7 million of the increase, as well as the results from the acquisition
of Polaroid Corporation's Freetown, Massachusetts fine chemicals facility
($1.6 million) (see Note 2 to Consolidated Financial Statements).  The
improved operating income also reflected higher gross margins in specialty
chemicals, partially offset by the impact of the stronger U.S. dollar.
Operating income for the mineral products business decreased slightly as
the higher sales levels were offset by lower gross profit margins.

     Interest expense for the second quarter increased slightly to $19.1
million from $18.9 million in the second quarter of 1997.  Other income,
net, for the second quarter of 1998 was $9.7 million compared with $7.3
million in the second quarter of 1997, principally reflecting higher
investment income, partially offset by foreign exchange losses.


Results of Operations - Six Months 1998 Compared With
                        Six Months 1997

     For the first six months of 1998, the Company recorded net income of
$34.7 million (64 cents diluted earnings per share) compared with $26.7
million (50 cents diluted earnings per share), for the first six months of
1997.  The 30% increase in net income was attributable to higher operating
and other income and, to a lesser extent, lower interest expense.







                                      10
<PAGE>
     Net sales for the first six months of 1998 were $420.5 million versus
net sales of $389.0 million for the same period in 1997, with the increase
attributable to the GhC acquisition ($20.0 million) and to increased sales
of specialty chemicals (excluding GhC sales) (up $8.1 million) and mineral
products (up $3.9 million), partially offset by lower filter products sales
(down $0.5 million).  The higher sales of specialty chemicals (excluding
GhC) resulted from increased sales volumes (up $16.1 million), partially
offset by the unfavorable effect of the stronger U.S. dollar ($8.0
million).  The 9% increase in mineral products was due to increased sales
volumes (up $3.2 million) and, to a lesser extent, favorable pricing.  The
sales growth resulted from sales increases in the U.S. and the Western
Hemisphere, partially offset by lower sales in the Asia-Pacific region and
Europe (excluding GhC), reflecting the unfavorable effect of the stronger
U.S. dollar.

     Operating income for the first six months of 1998 was $85.9 million, a
14% increase over the $75.4 million recorded in the first six months of
1997.  The increase in operating income was primarily attributable to the
acquisition of the remaining interest in GhC ($6.7 million) and improved
operating results in all business segments.  Specialty chemicals operating
income (excluding GhC) increased $3.1 million, of which $2.6 million was
attributable to the Freetown, Massachusetts fine chemicals acquisition, and
also reflected higher gross profit margins, offset by the negative impact
of the stronger U.S. dollar.  Operating income for the mineral products
business increased $0.6 million (6%) due to the higher sales levels.

     Interest expense for the first six months was $37.0 million compared
with $37.5 million in the same period in 1997, with the decrease due
primarily to lower average borrowings.  Other income, net, for the first
six months of 1998 was $19.7 million compared with $13.4 million last year,
principally reflecting higher investment income, partially offset by
foreign exchange losses.


Liquidity and Financial Condition

     During the first six months of 1998, the Company's net cash outflow
before financing activities was $62.9 million, including $114.7 million of
cash generated from operations, the reinvestment of $118.1 million for
capital programs and acquisitions (see below and Note 2 to Consolidated
Financial Statements), $56.1 million of cash generated from a sale-
leaseback related to an acquisition, and the use of $115.5 million of cash
for net purchases of available-for-sale and held-to-maturity securities.

     Cash from operations reflected a $30.6 million cash inflow from net
sales of trading securities and also included $6.1 million of dividends
received from the GhC joint venture prior to the Company's acquisition of
the remaining interest in GhC.  Working capital increased by $3.5 million,
primarily reflecting a $28.1 million increase in receivables due to $33.9
million higher sales in June 1998 versus December 1997 and an increase in
the receivable from the purchaser of the Company's domestic trade accounts
receivable, partially offset by a $0.8 million decrease in inventories and
a $26.4 million increase in payables.

                                       
                                       
                                       
                                      11
<PAGE>
     Net cash provided by financing activities in the six months of 1998
totaled $93.4 million, mainly reflecting a $51.6 million increase in short-term
borrowings, a $38.0 million increase in borrowings under the Company's bank
revolving credit facility and $4.0 million proceeds from the sale of the
Company's accounts receivable.

     As a result of the foregoing factors, cash and cash equivalents increased
by $30.6 million during the first six months of 1998 to $51.1 million
(excluding $314.9 million of trading and available-for-sale securities and
other short-term investments).

     As of June 28, 1998, the Company's scheduled repayments of long-term debt
for the twelve months ending June 30, 1999 aggregated $38.6 million, excluding
$200 million relating to the Company's 9% Senior Notes due March 1999.  The
Company intends to refinance the 9% Senior Notes; accordingly, such notes are
classified as long-term debt on the Consolidated Balance Sheet.

     In February 1998, the Company acquired Polaroid Corporation's Freetown,
Massachusetts fine chemicals facility.  In connection with the acquisition, the
Company entered into a sale-leaseback arrangement of the facility's equipment
with a third party.  The lease has been accounted for as an operating lease,
with an initial term of four years and, at the Company's option, up to three
one-year renewal periods.  As part of the transaction, the Company entered into
a long-term supply and license agreement with Polaroid for the imaging
chemicals and polymers manufactured at the facility and used by Polaroid in its
instant film business.

     Effective April 1, 1998, the Company acquired the remaining 50% interest
in the GhC joint venture.  As part of the transaction, the Company also
acquired Huls' production facility that supplies GhC with its primary raw
material, acetylene.  See Note 2 to Consolidated Financial Statements.

     On July 15, 1998, Old ISP merged with and into the Company.
See Note 1 to Consolidated Financial Statements.

     On July 22, 1998, the Company filed a shelf Registration Statement on Form
S-3 with the U.S. Securities and Exchange Commission for $1 billion of debt and
equity securities.  In addition to debt refinancing, the net proceeds of any
offering, if consummated, are expected to be used for general corporate
purposes.

     The Company is in the process of implementing a new global information
system for capturing, processing and analyzing data relating to manufacturing,
customer service, sales order entry, inventory control and financial systems.
In conjunction with this initiative, the Company is addressing its "Year 2000"
compliance issues and does not believe that the costs associated with, or the
impact of, these issues will have a material adverse effect on the operations,
liquidity or capital resources of the Company.  At this time, the Company is in
the process of reviewing the Year 2000 compliance issues of its major suppliers
and customers.

     See Note 6 to Consolidated Financial Statements for information regarding
contingencies.
