            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)


     The consolidated financial statements for ISP Chemco Inc. (the "Company")
reflect, in the opinion of management, all adjustments necessary to present
fairly the financial position of the Company and its consolidated subsidiaries
at September 28, 2003, and the results of operations and cash flows for the
three and nine month periods ended September 29, 2002 and September 28, 2003.
All adjustments are of a normal recurring nature. These consolidated financial
statements should be read in conjunction with the annual consolidated financial
statements and notes thereto included in the Company's Annual Report on Form
10-K for the fiscal year ended December 31, 2002 (the "2002 Form 10-K").


NOTE 1.  CHARGE FOR EARLY RETIREMENT OF DEBT

     On January 14, 2002, the Company's indirect parent company, International
Specialty Products Inc. ("ISP"), redeemed the remaining $307.9 million aggregate
principal amount of its 9% Senior Notes due 2003 (the "2003 Notes"), of which
$182.1 million was reflected on the Company's Consolidated Balance Sheet at
December 31, 2001. As a result, the Company recorded an extraordinary loss on
the early retirement of debt of $2.8 million ($4.3 million before income tax
benefit of $1.5 million). In April 2002, the Financial Accounting Standards
Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No.
145, "Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB
Statement No. 13, and Technical Corrections." SFAS No. 145 eliminates the
requirement of SFAS No. 4 that gains and losses on the early extinguishments of
debt be recorded as an extraordinary item unless such gains and losses meet the
criteria of Accounting Principles Board Opinion No. 30 for classification as
extraordinary. The Company adopted SFAS No. 145 effective January 1, 2003 and,
as a result, the Consolidated Statement of Operations for the first nine months
of 2002 was restated to reclassify the pre-tax extraordinary charge of $4.3
million on the early retirement of debt to a separate line item of pre-tax
income. The tax benefit of $1.5 million related to the extraordinary charge has
been reclassified and is included in "Income taxes."


NOTE 2.  ASSET RETIREMENT OBLIGATIONS

     The Company  adopted SFAS  No. 143,  "Accounting for  Asset Retirement
Obligations," effective January 1, 2003. SFAS No. 143 establishes accounting and
reporting standards for legal obligations associated with the retirement of
long-lived assets that result from the acquisition, construction, development
and the normal operation of a long-lived asset. The Company holds long-lived
assets that have legal obligations associated with their retirement. These
assets include deep wells that require capping, minerals quarries that require
reclamation and other plant assets subject to certain environmental regulations.
SFAS No. 143 requires that the fair value of a liability for an asset retirement
obligation ("ARO") be recognized in the period in which it is incurred. Upon
initial recognition of such liability, an entity must capitalize the asset
retirement cost by increasing the carrying amount of the related long-lived
asset and subsequently depreciating the asset retirement cost over the useful
life of the related asset. Subsequent to the initial measurement of the ARO, the
obligation will be adjusted at the end of each period to reflect the passage of
time and changes in the estimated future cash flows underlying the obligation.
If the obligation is settled for other than the carrying amount of the
liability, the Company would then recognize a gain or loss on settlement. As a
result of adopting SFAS No. 143, effective January 1, 2003, the Company
recognized an after-tax charge of $1.0 million ($1.6 million before an income
tax benefit of $0.6 million) as the cumulative effect of a change in accounting
principle, and recorded an ARO of $1.9 million and a net increase in

                                       5

NOTE 2.  ASSET RETIREMENT OBLIGATIONS -- (CONTINUED)

property, plant and equipment of $0.3 million. The ongoing expense on an annual
basis resulting from the initial adoption of SFAS No. 143 is approximately $0.2
million.

      The change in the ARO during the nine months ended September 28, 2003 is
as follows:

                                                                  (Thousands)
       ARO liability recognized as of January 1, 2003............   $  1,871
       Liabilities incurred, nine months ended September 28, 2003         22
       ARO liability accretion...................................        135
                                                                    --------
       ARO liability balance, September 28, 2003.................   $  2,028
                                                                    ========

     The pro forma ARO would have been $1.7 million on January 1, 2002 and $1.8
million on September 29, 2002 if SFAS No. 143 had been applied during all
periods affected.

     For the nine months ended September 29, 2002, the net loss on a pro forma
basis would have been $120.3 million, including an additional $0.1 million due
to additional depreciation and liability accretion from AROs. The net income for
the nine months ended September 28, 2003 would have increased on a pro forma
basis by $1.0 million to $40.4 million due to the elimination of the cumulative
effect of the change in accounting principle recorded on January 1, 2003 on the
adoption of SFAS No. 143. For the third quarter of 2002, the pro forma net
income would have been $40 thousand lower, while for the third quarter of 2003,
actual and pro forma net income are the same.


NOTE 3.  NEW ACCOUNTING STANDARDS


     In June  2002, the FASB  issued SFAS No. 146,  "Accounting for Costs
Associated with Exit or Disposal Activities." SFAS No. 146 addresses financial
accounting and reporting for costs associated with exit or disposal activities
and supercedes Emerging Issues Task Force Issue No. 94-3, "Liability Recognition
for Certain Employee Termination Benefits and Other Costs to Exit an Activity
(including Certain Costs Incurred in a Restructuring)." SFAS No. 146 requires
that a liability for a cost associated with an exit or disposal activity be
recognized when the liability is incurred, and concludes that an entity's
commitment to an exit plan does not by itself create a present obligation that
meets the definition of a liability. This Statement also establishes that fair
value is the objective for initial measurement of the liability. SFAS No. 146 is
effective for exit or disposal activities that are initiated after December 31,
2002. As the Company has no plans at this time for any exit or disposal
activities, the adoption of SFAS No. 146 will not have any immediate effect on
the Company's consolidated financial statements.

     In December  2002, the FASB  issued  SFAS No. 148,  "Accounting for
Stock-Based Compensation - Transition and Disclosure," an amendment of SFAS No.
123, "Accounting for Stock-Based Compensation." SFAS No. 148 provides
alternative methods of transition for an entity that voluntarily changes to the
fair value based method of

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)


NOTE 3.  NEW ACCOUNTING STANDARDS -- (CONTINUED)


accounting for stock-based employee compensation. In addition, SFAS No. 148
amends the disclosure requirements of SFAS No. 123 for both annual and interim
reporting periods by requiring disclosures in a tabular format to reconcile net
income as reported to pro forma net income as if the fair value method was used.
Certain of the disclosure modifications required for fiscal years ending after
December 15, 2002 were disclosed in the Company's 2002 Form 10-K. However, as
discussed in Note 4, with the completion of the going private transaction by ISP
in February 2003, the Company's stock-based compensation plans were terminated
and payments were made in accordance with the terms of the merger agreement.
Therefore, the provisions of SFAS No. 148 are no longer applicable to the
Company as it relates to those plans. In addition, the Company currently
accounts for incentive units granted to eligible Company employees pursuant to
ISP's 2000 Long-Term Incentive Plan and 2003 Executive Long-Term Incentive Plan
under the accounting prescribed by FASB Interpretation No. ("FIN") 28,
"Accounting for Stock Appreciation Rights and Other Variable Stock Option and
Award Plans," which requires an entity to measure compensation as the amount by
which the Book Value (as defined) of the incentive units covered by the grant
exceeds the option price or value specified of such incentive units at the date
of grant. Changes, either increases or decreases, in the Book Value of those
incentive units between the date of grant and the measurement date result in a
change in the measure of compensation for the right or award. The Company
expects to continue to account for its long-term incentive units under the
accounting prescribed by FIN 28 and has adopted the additional disclosure
provisions of SFAS No. 148. Since compensation expense related to such incentive
units is included in the actual Consolidated Statements of Operations, the
Company's pro forma net income under SFAS No. 123 would have been the same as
actual net income.

     In November  2002, the FASB  issued FIN 45,  "Guarantor's Accounting and
Disclosure Requirements for Guarantees, Including Indirect Guarantees of
Indebtedness of Others." FIN 45 clarifies the requirements for a guarantor's
accounting for and disclosures of certain guarantees issued and outstanding. The
provisions of FIN 45 apply to guarantee contracts that contingently require the
guarantor to make payments (in cash, financial instruments, other assets, shares
of stock or provision of services) to the guaranteed party for guarantees such
as a financial standby letter of credit, a market value guarantee on either a
financial or nonfinancial asset owned by the guaranteed party and a guarantee of
the collection of the scheduled contractual cash flows from financial assets
held by a special-purpose entity. FIN 45 also applies to indemnification
contracts and indirect guarantees of indebtedness of others. The requirements of
FIN 45 for the initial recognition and measurement of the liability for a
guarantor's obligations are to be applied only on a prospective basis to
guarantees issued or modified after December 31, 2002. The Company currently
does not have any guarantees, indemnification contracts or indirect guarantees
of indebtedness of others that would be subject to the initial recognition and
measurement provisions of FIN 45. As discussed in Note 10, the Company's 10 1/4%
Senior Subordinated Notes due 2011 that were issued in November 2001 are
guaranteed by all of the Company's domestic subsidiaries, other than certain
immaterial subsidiaries and the Company's accounts receivable financing
subsidiary.

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)


NOTE 3.  NEW ACCOUNTING STANDARDS -- (CONTINUED)

     In January  2003, the FASB  issued FIN 46,  "Consolidation of Variable
Interest Entities." In accordance with FIN 46, a variable interest entity will
be consolidated if either the total equity investment at risk is not sufficient
to permit the entity to finance its activities without additional subordinated
financial support from other parties, or as a group, the holders of the equity
investment at risk lack any one of the following three characteristics of a
controlling financial interest: (1) the direct or indirect ability to make
decisions about an entity's activities; (2) the obligation to absorb the
expected losses of the entity if they occur; (3) the right to receive the
expected residual returns of the entity if they occur. All companies with
variable interests in variable interest entities created after January 31, 2003
shall apply the provisions of FIN 46 immediately. A public entity with a
variable interest in a variable interest entity created before February 1, 2003
shall apply the provisions of FIN 46 to that entity no later than the beginning
of the first interim or annual reporting period ending after December 15, 2003,
if such entity has not issued financial statements reporting that variable
interest entity in accordance with FIN 46. The Company does not have an interest
in a variable interest entity. Therefore, the adoption of FIN 46 does not
currently have an impact on the Company's consolidated financial statements.

     In April 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133
on Derivative Instruments and Hedging Activities." SFAS No. 149 amends and
clarifies financial accounting and reporting for derivative instruments and
hedging activities under SFAS No. 133. SFAS No. 149 is effective for contracts
entered into or modified after June 30, 2003 and for hedging relationships
designated after June 30, 2003. The adoption of SFAS No. 149 will not have an
immediate impact on the Company's consolidated financial statements.


NOTE 4.  OTHER OPERATING GAINS AND CHARGES

     On February 28, 2003, ISP completed a going private transaction whereby
stockholders of ISP approved the Agreement and Plan of Merger dated as of
November 8, 2002 of International Specialty Products Holdings Inc. with and into
ISP and pursuant to which holders of ISP common stock received $10.30 per share
in cash for each share of ISP common stock owned (except as otherwise provided
in the merger agreement). As a result of completing this going private
transaction, the Company's stock-based compensation plans were terminated and
payments were made in accordance with the terms of the merger agreement. As a
result, holders of approximately 2.7 million vested, in-the-money stock options
outstanding and exercisable on February 28, 2003 received a cash amount equal to
the excess of $10.30 over the exercise price of such stock options, aggregating
$1.5 million. Compensation expense of $1.5 million related to the payment for
stock option terminations was recorded in the first quarter of 2003 and is
included in "Other operating gains and (charges), net." In addition, outstanding
restricted common stock awards were replaced with long-term incentive units of
comparable vesting and a value equivalent to the previous awards based on the
buyout price of $10.30 per award. First quarter 2002 results included an other
operating gain of $2.8 million for a contract termination related to the sale of
the Company's FineTech business. The Company recorded an additional second
quarter 2002 pre-tax gain, after expenses, of $5.5 million related to this sale.
In the second quarter of 2002, the Company received $4.0 million in settlement
of a

manufacturing and supply contract with a customer of the fine chemicals
business. After related expenses, a pre-tax gain of $3.9 million was recognized.
For additional information, reference is made to Note 6 to Consolidated
Financial Statements contained in the 2002 Form 10-K.


NOTE 5.  2003 EXECUTIVE LONG-TERM INCENTIVE PLAN

     In May 2003, ISP adopted the 2003 Executive Long-Term Incentive Plan (the
"Plan"), which authorizes the grant of incentive units ("Incentive Units") to
eligible employees of the Company. The Plan is administered by a committee (the
"Committee") appointed by the Board of Directors of ISP from among the employees
of ISP. The Committee, in its sole discretion, determines the number of
Incentive Units to be granted to each eligible employee. The Plan will terminate
ten years after its effective date of May 15, 2003.


NOTE 6.  GOODWILL AND INTANGIBLE ASSETS

     On June 30, 2001, the FASB issued SFAS No. 142, "Goodwill and Other
Intangible Assets". With the adoption of SFAS No. 142, goodwill is no longer
subject to amortization over its estimated useful life. However, goodwill is
subject to at least an annual assessment for impairment and more frequently if
circumstances indicate a possible impairment. The Company adopted SFAS No. 142
effective as of January 1, 2002. Accordingly, during the second quarter of 2002,
the Company completed a transitional impairment test, effective January 1, 2002,
and recognized a goodwill impairment loss of $155.4 million as the cumulative
effect of a change in accounting principle.

     The following  schedule reconciles  the changes in  the carrying amount of
goodwill, by business segment, for the nine months ended September 28, 2003. See
Note 8 for a discussion of a change in the composition of the Company's business
segments, effective January 1, 2003. Also, see Note 10 for a discussion of the
acquisition of Germinal S.A.

(1)  Effective January 1, 2003, the Company changed the composition of its
     reportable segments to be consistent with the current structure of the
     Company's businesses. Over the last several years, the Company has
     increased its focus on its higher margin consumer-oriented businesses.
     Consistent with that business focus, the Company now reports three business
     segments: Specialty Chemicals, Industrial Chemicals and Mineral Products.
     The Company's Specialty Chemicals segment consists of the personal care,
     pharmaceutical, food, beverage, performance chemicals and fine chemicals
     product lines. Sales and operating income by business segment for the third
     quarter and nine months ended September 29, 2002 have been restated to
     conform to the 2003 presentation.

(2)  Includes sales to Building Materials Corporation of America, an affiliate,
     and its subsidiaries, of $19.1 and $19.5 million for the third quarter of
     2002 and 2003, respectively, and $57.9 and $59.2 for the first nine months
     of 2002 and 2003, respectively.

                                        ========      ========

     At December 31, 2002 and September 28, 2003, $62.0 and $64.5 million,
respectively, of domestic inventories were valued using the LIFO method. If the
FIFO inventory method had been used for these inventories, the value of
inventories would have been $2.8 and $4.5 million higher at December 31, 2002
and September 28, 2003, respectively.


NOTE 10.  ACQUISITION

     In May  2003, the Company  acquired 100% of  the stock  of Germinal S.A.,
a supplier of food ingredients to the meat and dairy industry in southern Latin
America, for $7.3 million in cash, net of $0.4 million cash acquired. Germinal
has a manufacturing facility at its headquarters in Cabreuva, Brazil. In
accordance with SFAS No. 141, "Business Combinations," the purchase price was
allocated on a preliminary basis to the estimated fair value of the identifiable
assets acquired, primarily property plant and equipment, and the excess of $5.5
million was recorded as goodwill. The Company is in the process of evaluating
the fair value of the net assets acquired and, therefore, the purchase price
allocation is subject to refinement. The results of the Germinal business are
included in the Company's results of operations from the date of acquisition and
are not expected to have a material impact on the Company's results of
operations for the year 2003.


NOTE 11. GUARANTOR FINANCIAL INFORMATION

     In 2001, the Company and three of its wholly owned subsidiaries jointly
issued, in three separate transactions, a total of $405.0 million aggregate
principal amount of 10 1/4% Senior Subordinated Notes due 2011 (the "2011
Notes"). The 2011 Notes are guaranteed by all of the Company's domestic
subsidiaries, other than certain immaterial subsidiaries and the Company's
accounts receivable financing subsidiary. These guarantees are full,
unconditional and joint and several.

     ISP Global Technologies Inc., which is a guarantor of the 2011 Notes, is
party to a License and Royalty Agreement with non-guarantor foreign affiliates.
Under this agreement, ISP Global Technologies granted a license to certain
non-guarantor foreign affiliates for the use of the Patent Rights, Know-how and
Trademarks in connection with the manufacture, use and sale of the Company's
products.

NOTE 12.  CONTINGENCIES

Environmental Litigation

     The Company, together with other companies, is a party to a variety of
proceedings and lawsuits involving environmental matters ("Environmental
Claims") under the Comprehensive Environmental Response Compensation and
Liability Act, Resource Conservation and Recovery Act and similar state laws, in
which recovery is sought for the cost of cleanup of contaminated sites or
remedial obligations are imposed. A number of these Environmental Claims are in
the early stages or have been dormant for protracted periods.

     While the Company cannot predict whether adverse decisions or events can
occur in the future, 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 increases in remedial costs,
discovery of new contamination, assertion of natural resource damages, and 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 those 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 21 to Consolidated Financial Statements contained in the 2002 Form 10-K.

Tax Claim Against G-I Holdings Inc.

     The predecessor of ISP and certain of its domestic subsidiaries were
parties to tax sharing agreements with members of a consolidated group for
Federal income tax purposes that included G-I Holdings Inc. (the "G-I Holdings
Group") in certain prior years. Until January 1, 1997, ISP and its domestic
subsidiaries were included in the consolidated Federal income tax returns of the
G-I Holdings Group and, accordingly, would be severally liable for any tax
liability of the G-I Holdings Group in respect of those prior years. Those tax
sharing agreements are no longer applicable with respect to the tax liabilities
of ISP for periods subsequent to January 1, 1997, because neither the Company
nor any of its domestic subsidiaries are members of the G-I Holdings Group for
periods after January 1, 1997. In January 2001, G-I Holdings filed a voluntary
petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code due to
its asbestos-related bodily injury claims relating to the inhalation of asbestos
fiber.

     On September 15, 1997,  G-I Holdings  received a  notice from the Internal
Revenue Service (the "IRS") 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 G-I Holdings held an
interest. G-I Holdings has advised the Company that it believes that it will
prevail in the tax matter arising out of the surfactants partnership, 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
business, financial position or results of operations. On September 21, 2001,
the IRS filed a proof of claim with respect to

NOTE 12. CONTINGENCIES -- (CONTINUED)

such deficiency against G-I Holdings and one of its subsidiaries, ACI Inc., that
also filed for protection under Chapter 11 of the Bankruptcy Code, in the G-I
Holdings bankruptcy. If such proof of claim is sustained, ISP and/or certain of
its subsidiaries together with G-I Holdings and several current and former
subsidiaries of G-I Holdings would be severally liable for taxes and interest in
an amount of approximately $279 million, computed as of September 28, 2003. On
May 7, 2002, G-I Holdings filed an objection to that proof of claim. Such
objection will be heard by the United States District Court for the District of
New Jersey which oversees the G-I Holdings bankruptcy court. For additional
information relating to G-I Holdings, reference is made to Notes 9 and 21 to
Consolidated Financial Statements contained in the 2002 Form 10-K.

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


     Unless otherwise indicated by the context, "we," "us" and "our" refer to
ISP Chemco Inc. and its consolidated subsidiaries.


RESULTS OF OPERATIONS -- THIRD QUARTER 2003 COMPARED WITH
                         THIRD QUARTER 2002

     We recorded third quarter 2003 net income of $11.1 million compared with
net income of $10.9 million in the third quarter of 2002. The higher results for
the third quarter of 2003 were attributable to $2.3 million lower other expense,
net, and $1.0 million lower interest expense, partially offset by $3.5 million
lower operating income.

     Effective January 1, 2003, we changed the composition of our reportable
segments to be consistent with the current structure of our businesses. Over the
last several years, we have increased our focus on our higher margin
consumer-oriented businesses. Consistent with that business focus, we now report
three business segments: Specialty Chemicals, Industrial Chemicals and Mineral
Products. Our Specialty Chemicals segment consists of the personal care,
pharmaceutical, food, beverage, performance chemicals and fine chemicals product
lines. Sales and operating income by business segment for the third quarter and
nine months ended September 29, 2002 have been restated to conform to the 2003
presentation.

     Net sales for the third quarter of 2003 were $215.1 million compared with
$208.4 million for the third quarter of 2002. The $6.7 million (3%) increase in
sales resulted from higher unit volumes in the Mineral Products segment ($4.0
million) and in the pharmaceutical and food product lines (totaling $4.8
million) and the favorable impact of the weaker U.S. dollar in Europe ($8.1
million). These sales gains were partially offset by lower pricing in Industrial
Chemicals and Mineral Products (totaling $4.0 million) and lower unit volumes in
the fine chemicals product line ($4.2 million).

     The gross margin for the third quarter of 2003 was 34.7% compared with
36.6% in the third quarter of 2002. The reduced margin resulted primarily from
the impact of the unfavorable pricing in Industrial Chemicals and Mineral
Products and unfavorable manufacturing costs in Mineral Products and fine
chemicals (totaling $7.7 million), partially offset by higher unit volumes and
the favorable impact of the weaker U.S. dollar.

     Operating income was $32.1 million in the third quarter of 2003 compared
with $35.6 million in the third quarter of 2002. Operating income for the
Specialty Chemicals segment improved 7% to $29.8 million compared with $27.8
million in the third quarter of 2002. The improved results for Specialty
Chemicals were primarily attributable to the personal care and pharmaceutical
product lines, mainly due to manufacturing efficiencies and the favorable impact
of the weaker U.S. dollar, partially offset by losses in the fine chemicals
product line.

                                       21

<PAGE>

     The Industrial Chemicals segment recorded an operating loss of $1.2 million
in the third quarter of 2003 compared with operating income of $2.1 million in
the third quarter of 2002. The Industrial Chemicals manufacturing operations are
principally based in Europe and costs for this business have been adversely
impacted by the stronger Euro. In addition, the results for the third quarter of
2003 were impacted by lower pricing due to current industry supply/demand
imbalance.

     Operating income for the Mineral Products segment decreased by $2.0 million
(36%) to $3.5 million in the third quarter of 2003 because of unfavorable
manufacturing costs, primarily higher energy costs, as well as lower pricing.

     Selling, general and administrative expenses for the third quarter of 2003
increased by 4% to $42.4 million from $40.6 million in the same period last year
as a result of higher selling and administrative costs, mainly due to the weaker
U.S. dollar. Selling, general and administrative expenses as a percentage of
sales were 19.7% compared with 19.5% in last year's third quarter.

     Interest expense for the third quarter of 2003 was $13.1 million compared
with $14.1 million for the same period last year. The $1.0 million (7%) decrease
was primarily due to lower average borrowings ($0.6 million impact), as well as
lower average interest rates ($0.4 million impact). Other expense, net, for the
third quarter of 2003 was $2.0 million compared with $4.2 million in last year's
third quarter, with the lower expense due primarily to favorable foreign
exchange.

Business Segment Review

     A discussion of operating results for each of our business segments
follows. We operate our business through three reportable business segments:
Specialty Chemicals; Industrial Chemicals; and Mineral Products. As discussed
above, we changed the composition of our reportable segments, effective January
1, 2003. Sales and operating income by business segment for the third quarter of
2002 have been restated to conform to the 2003 presentation. See also Note 8 to
consolidated financial statements.


Specialty Chemicals

     Sales in  the third  quarter of  2003 were  $153.5 million compared with
$149.3 million for the same period last year, while operating income for the
third quarter of 2003 was $29.8 million compared with $27.8 million in last
year's third quarter. The 3% increase in sales was attributable to higher unit
volumes in the pharmaceutical and food product lines (totaling $4.8 million),
and the favorable effect of the weaker U.S. dollar in Europe ($5.9 million).
Partially offsetting these sales increases were lower unit volumes in the fine
chemicals product line ($4.2 million) and lower pricing ($1.0 million),
primarily in the personal care product line, and lower unit volumes in the
personal care and performance chemicals product lines (totaling $2.3 million).
Higher pharmaceutical volumes were primarily attributable to strong growth in
the excipients markets (Plasdones

                                       22

<PAGE>

for tablet binders and Polyplasdones for tablet disintegrants), as well as the
denture adhesives market, while higher food volumes resulted from the Germinal
acquisition in May 2003 (see Note 10 to consolidated financial statements).

     Operating income  for the Specialty  Chemicals segment  increased by 7%
for the third quarter of 2003 to $29.8 million compared with $27.8 million in
last year's third quarter. The improvement resulted primarily from the favorable
effect of the weaker U.S. dollar ($4.7 million) and the impact of favorable
manufacturing efficiencies and lower operating expenses in the personal care and
pharmaceutical product lines (totaling $4.4 million), partially offset by
unfavorable pricing ($1.0 million) and losses incurred in the fine chemicals
product line because of the adverse impact of unfavorable manufacturing costs
($6.6 million).

Industrial Chemicals

     Sales in  the third quarter  of 2003 were  $35.0 million compared with
$34.5 million in the third quarter of 2002. The increase in sales was
attributable to the favorable effect of the weaker U.S. dollar ($2.2 million),
partially offset by lower pricing.

     The Industrial Chemicals segment recorded an operating loss of $1.2 million
in the third quarter of 2003 compared with operating income of $2.1 million in
the third quarter of 2002. The Industrial Chemicals manufacturing operations are
principally based in Europe and costs for this business have been adversely
impacted by the stronger Euro. In addition, the results for the third quarter of
2003 were impacted by the lower pricing ($2.0 million) due to current industry
supply/demand imbalance.

Mineral Products

     Sales for  the Mineral  Products segment  for the third quarter of 2003
were $26.6 million compared with $24.6 million for the third quarter of 2002, as
higher unit volumes ($4.0 million) were partially offset by lower pricing ($2.0
million).

     Operating income for the third quarter of 2003 was $3.5 million compared
with $5.5 million for the third quarter of 2002. The $2.0 million (36%) decrease
in operating income was due to unfavorable manufacturing costs, primarily as a
result of higher energy costs, as well as lower pricing.


RESULTS OF OPERATIONS -- FIRST NINE MONTHS 2003 COMPARED WITH
                         FIRST NINE MONTHS 2002

     We have restated our previously issued consolidated financial statements
for the first nine months of 2002. See Note 1 and Note 9 to consolidated
financial statements for further information.

     For the first nine months of 2003, we recorded net income of $39.3 million
compared with a net loss of $120.2 million in the first nine months of 2002.
First nine months 2003 results include a $1.0 million after-tax charge for the
cumulative effect of a change in accounting principle from the adoption of
Statement of Financial

                                       23

<PAGE>


Accounting Standards, which we refer to as "SFAS," No. 143, "Accounting for
Asset Retirement Obligations." First nine months 2002 results included a $155.4
million goodwill impairment charge, effective January 1, 2002, for the
cumulative effect of a change in accounting principle related to the adoption
of SFAS No. 142, "Goodwill and Other Intangible Assets."

     Income before the cumulative effect of changes in accounting principles was
$40.4 million for the first nine months of 2003 compared with $35.2 million in
the first nine months of 2002. The improved results for the first nine months of
2003 were attributable to $6.1 million lower interest expense and $4.3 million
lower other expense, net, partially offset by $7.1 million lower operating
income. In addition, the results for the first nine months of 2002 included a
$4.3 million pre-tax charge for the early retirement of debt and other operating
gains of $12.2 million, while first nine months 2003 results include an other
operating charge of $1.5 million for stock option payments related to a going
private transaction by our parent company, International Specialty Products
Inc., which we refer to as ISP. The other operating gains of $12.2 million in
the first nine months of 2002 included a $2.8 million gain from a contract
termination related to the sale of our company's FineTech business, a $5.5
million gain on the sale of the FineTech business and a $3.9 million gain on a
contract settlement.

     Net sales for the first nine months of 2003 were $677.2 million compared
with $642.2 million for the first nine months of 2002. The $35.0 million (5.5%)
increase in sales resulted primarily from higher unit volumes in the Industrial
Chemicals and Mineral Products segments (totaling $17.8 million) and in the
pharmaceutical, food and beverage product lines (totaling $14.2 million) and the
favorable impact of the weaker U.S. dollar in Europe ($31.6 million). These
sales gains were partially offset by lower pricing in Industrial Chemicals,
Mineral Products and the personal care product line (totaling $9.9 million) and
lower volumes ($16.2 million) in the fine chemicals product line, mainly as a
result of the loss of sales to Polaroid, which is operating under bankruptcy
court protection.

     The gross margin for the first nine months of 2003 was 35.0% compared with
35.2% in the first nine months of 2002. Lower gross margins for the Mineral
Products and Industrial Chemicals segments were adversely impacted by higher
energy costs and lower pricing. The gross margin for the Specialty Chemicals
segment increased to 43.1% for the first nine months of 2003 from 39.3% for the
first nine months of 2002. The improvement was primarily attributable to
manufacturing efficiencies and the favorable impact of the weaker U.S. dollar.

     Operating income for the first nine months of 2003 was $103.7 million
compared with $110.8 million for the first nine months of 2002. Excluding the
other operating gains and charges in each period mentioned above, operating
income on a comparable basis was $105.2 million and $98.6 million for the first
nine months of 2003 and 2002, respectively (see reconciliation below of non-GAAP
financial measures). The higher comparable operating income for the first nine
months of 2003 includes improved results in the Specialty Chemicals segment,
partially offset by losses in the Industrial Chemicals segment and lower results
in the Mineral Products segment.

                                       24

<PAGE>

     On a comparable basis, excluding the aforementioned other operating gains
and charges, operating income for the Specialty Chemicals segment improved 31%
to $97.8 million compared with $74.9 million in last year's first nine months.
The improved results were primarily attributable to the personal care,
pharmaceutical and beverage product lines, mainly due to manufacturing
efficiencies, higher unit volumes, lower operating expenses and the favorable
impact of the weaker U.S. dollar, partially offset by lower pricing. The
improved results in Specialty Chemicals were adversely impacted by the lack of
sales to Polaroid.

     The Industrial Chemicals segment recorded an operating loss of $5.3 million
in the first nine months of 2003 compared with operating income of $5.2 million
in the first nine months of 2002. The results were mainly attributable to lower
pricing and to the adverse impact of the stronger Euro on European-based
manufacturing costs and higher energy costs, partially offset by manufacturing
efficiencies.

     Operating income for the Mineral Products segment decreased by $6.2 million
(34%) to $12.2 million in the first nine months of 2003 due to unfavorable
manufacturing costs, primarily as a result of higher energy costs, as well as
lower pricing.

     Selling, general and administrative expenses for the first nine months of
2003 increased by 3.5% to $131.3 million from $126.8 million in the same period
last year as a result of higher administrative and distribution costs, mainly
due to the weaker U.S. dollar. Selling, general and administrative expenses as a
percentage of sales were reduced to 19.4% compared with 19.8% in last year's
first nine months.

     Interest expense for the first nine months of 2003 was $39.7 million
compared with $45.8 million for the same period last year. The $6.1 million
(13%) decrease was primarily due to lower average borrowings ($3.9 million
impact) and, to a lesser extent, lower average interest rates ($2.2 million
impact). Other expense, net, for the first nine months of 2003 was $1.9 million
compared with $6.2 million in last year's first nine months, with the lower
expense due primarily to favorable foreign exchange.


Business Segment Review

     A discussion of operating results for each of our business segments
follows. We operate our business through three reportable business segments:
Specialty Chemicals; Industrial Chemicals; and Mineral Products. As discussed
above, we changed the composition of our reportable segments, effective January
1, 2003. Sales and operating income by business segment for the first nine
months of 2002 have been restated to conform to the 2003 presentation. See also
Note 8 to consolidated financial statements.

     The business  segment review  below and the  discussion of  operating
income above contain information regarding non-GAAP financial measures contained
within the meaning of Item 10 of Regulation S-K promulgated by the Securities
and Exchange Commission. As used herein, "GAAP" refers to accounting principles
generally accepted in the United States of America.

                                       25

<PAGE>

We use non-GAAP financial measures to eliminate the effect of certain other
operating gains and charges on reported operating income. Management believes
that these financial measures are useful to investors and financial institutions
because such measures exclude transactions that are unusual due to their nature
or infrequency and therefore allow investors and financial institutions to more
readily compare our company's performance from period to period. Management uses
this information in monitoring and evaluating our company's performance and the
performance of individual business segments. The non-GAAP financial measures
included herein have been reconciled to the most directly comparable GAAP
financial measure as is required under Item 10 of Regulation S-K regarding the
use of such financial measures. These non-GAAP measures should be considered in
addition to, and not as a substitute, or superior to, operating income or other
measures of financial performance in accordance with generally accepted
accounting principles.

     sale of the FineTech business and a $3.9 million gain from the settlement
     of a manufacturing and supply agreement with a customer of the fine
     chemicals product line. All non-GAAP adjustments for the first nine months

Specialty Chemicals

     Sales in the  first nine  months of 2003  were $470.4 million  compared
with $455.6 million for the same period last year, while operating income for
the first nine months of 2003 increased by 11% to $96.7 million from $87.1
million in last year's first nine months. The 3% increase in sales was
attributable to the favorable effect of the weaker U.S. dollar ($22.3 million)
and higher unit volumes in the pharmaceutical, food and beverage product lines
(totaling $14.2 million). Partially offsetting these sales increases were lower
unit volumes ($16.2 million) in the fine chemicals product line, primarily as a
result of the loss of sales due to the termination of the supply and license
agreement with Polaroid ($7.3 million), and unfavorable pricing ($4.2 million),
primarily in the personal care product line in both the skin care (sunscreens
markets)and hair care (styling gel/lotion markets). Favorable pharmaceutical
volumes were primarily attributable to strong growth in the excipients markets
(Plasdones for tablet binders and Polyplasdones for tablet disintegrants), as
well as the denture adhesives market, while higher food volumes resulted from
the Germinal acquisition in May 2003 (see Note 10 to consolidated financial
statements).

     Excluding the  other operating  gains and charges  discussed  above,
operating income for the Specialty Chemicals segment increased by 31% for the
first nine months of 2003 to $97.8 million compared with $74.9 million in last
year's first nine months. The improvement resulted primarily from manufacturing
efficiencies ($7.2 million), the favorable effect of the weaker U.S. dollar
($15.5 million), the impact of higher unit volumes in the pharmaceutical, food
and beverage product lines (totaling $5.8 million) and lower operating expenses
($2.6 million), partially offset by unfavorable pricing ($4.2 million). The
improved results for this segment were adversely impacted by the lower volumes
in the fine chemicals product line ($5.2 million), mainly due to the loss of
sales to Polaroid.

Industrial Chemicals

     Sales in  the first nine  months of 2003  were $128.6  million compared
with $112.4 million in the first nine months of 2002. The 14% increase in sales
was attributable to higher unit volumes ($11.7 million) and the favorable effect
of the weaker U.S. dollar ($9.3 million), partially offset by the continuing
adverse effect of unfavorable pricing ($4.9 million).

     The Industrial Chemicals segment recorded an operating loss of $5.3 million
in the first nine months of 2003, compared with operating income of $5.2 million
in the first nine months of 2002. The unfavorable results for this business have
been adversely impacted by the stronger Euro on European-based manufacturing
costs. The unfavorable results also included higher energy costs and operating
expenses ($7.4 million) and unfavorable pricing ($4.9 million), partially offset
by manufacturing efficiencies ($4.9 million) and the impact of higher volumes
($2.2 million).

     There is  ongoing pressure  on our pricing and revenue  related  to
commodity type butanediol and related solvents and intermediates. A key
competitor in this market completed construction of additional production
capacity in Europe for these products during the third quarter of 2002.

                                       27

<PAGE>


Another competitor is expected to complete construction of additional capacity
in Asia during the fourth quarter of 2003. With the opening of these two
facilities, the increase in the supply of these products to the merchant market
is resulting in increased downward pressure on pricing.

Mineral Products

     Sales for  the Mineral Products  segment for  the first  nine months of
2003 were $78.3 million compared with $74.3 million for the first nine months of
2002. The 5% increase was due to higher unit volumes ($6.1 million) and included
$2.7 million (16%) in higher third party sales and $1.3 million (2%) in higher
sales to Building Materials Corporation of America, an affiliate, which we refer
to as BMCA.

     Operating income for the first nine months of 2003 was $12.2 million
compared with $18.4 million for the first nine months of 2002. The $6.2 million
(34%) decrease in operating income was due to unfavorable manufacturing costs,
primarily as a result of higher energy costs and, to a lesser extent,
unfavorable pricing ($2.1 million).


LIQUIDITY AND FINANCIAL CONDITION

Cash Flow and Cash Position

     During the  first nine  months of 2003,  our net cash  flow  before
financing activities was $8.2 million and included $57.8 million of cash
generated from operations and the reinvestment of $49.7 million for capital
programs and the acquisition of Germinal S.A. (see Note 10 to consolidated
financial statements). Cash generated from operations in the first six months of
2003 of $57.8 million included a cash outflow of $13.1 million due to an
increase in receivables from related parties, primarily related to an
acquisition by our parent company, ISP. Cash invested in additional working
capital items totaled $32.2 million during the first six months of 2003,
including a $19.1 million increase in receivables as a result of higher sales, a
$6.3 million increase in inventories and an $8.2 million decrease in payables
and accrued liabilities, primarily related to payments of accrued interest.

     Net cash  used in financing  activities during  the first six  months of
2003 totaled $0.2 million and included repayments of long-term debt totaling
$1.6 million, offset by a $1.5 million capital contribution from ISP for the
payment of stock option terminations related to ISP's going private transaction
in February 2003.

     As a  result of  the foregoing  factors, cash  and cash  equivalents
increased by $11.0 million during the first nine months of 2003 to $44.3
million.

Current Maturities of Long-Term Debt

     As of September 28, 2003, our current maturities of long-term debt,
scheduled to be repaid during the twelve month period ended September 2004,
totaled $2.7 million, including $2.3 million related to the term loan under our
senior credit facilities.

                                       28

Freetown Facility

     As part of our acquisition of our Freetown, Massachusetts plant in 1998, we
entered into a multi-year agreement to supply the imaging dyes and polymers used
by Polaroid in its instant film business. In October 2001, Polaroid filed for
protection under Chapter 11 of the U.S. Bankruptcy Code. In the third quarter of
2002, the majority of Polaroid's assets were acquired by a new owner, and the
new owner did not assume our long-term supply contract with Polaroid. These
events negatively impacted the sale of our fine chemicals products and reduced
the utilization of our Freetown plant. We have since increased the utilization
of the Freetown facility, primarily from additional production of personal care
products.

     An operating lease related to equipment at the Freetown facility was
entered into as part of a 1998 sale-leaseback transaction. The lease had an
initial term of four years and, at our option, up to three one-year renewal
periods. The first renewal term commenced during the first quarter of 2002. The
lease provides for a substantial guaranteed payment by us, adjusted at the end
of each renewal period, and includes purchase and return options at fair market
values determined at the inception of the lease. We have the right to exercise a
purchase option with respect to the leased equipment, or the equipment can be
returned to the lessor and sold to a third party. We are obligated to pay a
maximum guaranteed payment amount upon the return of the equipment, currently
$32.6 million, reduced by 50% of any proceeds from the subsequent sale of the
equipment in excess of $4.8 million.

Contractual Obligations

     We have a contract with a multinational supplier to supply a substantial
amount of our acetylene needs to our Texas City, Texas facility. This supplier
generates this raw material as a by-product from the manufacture of ethylene.
Pricing under the contract is on a fixed basis and we are obligated to purchase
a specified amount of acetylene under the contract. This supplier has closed its
operation that was the primary source of acetylene for our Texas City facility.
The supplier has an obligation to provide product to us until the end of March
2004 and has confirmed that it will meet this obligation through that date by
delivering product from another of its facilities. We have identified several
alternative sources of supply of acetylene for the Texas City facility for the
period after March 2004. The annualized, incremental cost of acetylene from
these sources is estimated to be less than $2.0 million. Although we believe
that these alternative sources of supply will be sufficient for our projected
needs, there can be no assurance in this regard.

     We also had a contract with another supplier for the delivery of additional
amounts of acetylene to our Texas City facility, which expired on June 30, 2003.
We have entered into a five-year contract with an alternative source under which
we are obligated to purchase specified quantities of acetylene. Pricing is fixed
with escalators tied to the Producer Price Index.

     In May 2003, we entered into a long-term contract with BMCA to supply BMCA
and its subsidiaries substantially all of their colored roofing granules and
algae-resistant granules requirements, except for the requirements of certain of
their roofing plants that are supplied by third

                                       29

<PAGE>

parties. The contract includes pricing discounts based on volume purchase
targets, which, if the highest discount levels are reached over the term of the
contract, could adversely impact gross margins for the Mineral Products segment.
Our supply arrangements with BMCA and its subsidiaries are at prices and on
terms that we believe are no less favorable to it than could be obtained from
an unaffiliated third party.

New Accounting Standards

     In June  2002, the FASB  issued SFAS No. 146,  "Accounting  for Costs
Associated with Exit or Disposal Activities." SFAS No. 146 addresses financial
accounting and reporting for costs associated with exit or disposal activities
and supercedes Emerging Issues Task Force Issue No. 94-3, "Liability Recognition
for Certain Employee Termination Benefits and Other Costs to Exit an Activity
(including Certain Costs Incurred in a Restructuring)." SFAS No. 146 requires
that a liability for a cost associated with an exit or disposal activity be
recognized when the liability is incurred, and concludes that an entity's
commitment to an exit plan does not by itself create a present obligation that
meets the definition of a liability. This Statement also establishes that fair
value is the objective for initial measurement of the liability. SFAS No. 146 is
effective for exit or disposal activities that are initiated after December 31,
2002. As we have no plans at this time for any exit or disposal activities, the
adoption of SFAS No. 146 will not have any immediate effect on our consolidated
financial statements.

     In December  2002, the FASB  issued SFAS  No. 148,  "Accounting for
Stock-Based Compensation - Transition and Disclosure," an amendment of SFAS No.
123, "Accounting for Stock-Based Compensation." SFAS No. 148 provides
alternative methods of transition for an entity that voluntarily changes to the
fair value based method of accounting for stock-based employee compensation. In
addition, SFAS No. 148 amends the disclosure requirements of SFAS No. 123 for
both annual and interim reporting periods by requiring disclosures in a tabular
format to reconcile net income as reported to pro forma net income as if the
fair value method was used. Certain of the disclosure modifications required for
fiscal years ending after December 15, 2002 were disclosed in our 2002 Form
10-K. However, as discussed above, with the completion of the going private
transaction by ISP in February 2003, our stock-based compensation plans were
terminated and payments were made in accordance with the terms of the merger
agreement. Therefore, the provisions of SFAS No. 148 are no longer applicable to
us as it relates to those plans. In addition, we currently account for incentive
units granted to our eligible employees pursuant to ISP's 2000 Long-Term
Incentive Plan and 2003 Executive Long-Term Incentive Plan under the accounting
prescribed by FASB Interpretation No. 28, which we refer to as FIN 28,
"Accounting for Stock Appreciation Rights and Other Variable Stock Option and
Award Plans," which requires an entity to measure compensation as the amount by
which the Book Value of the incentive units covered by the grant exceeds the
option price or value specified of such incentive units at the date of grant.
Changes, either increases or decreases, in the Book Value of those incentive
units between the date of grant and the measurement date result in a change in
the measure of compensation for the right or award. We expect to continue to
account for our long-term incentive units under the accounting prescribed by FIN
28 and have adopted the additional disclosure provisions of SFAS No. 148. Since
compensation expense related to such incentive units is included in the actual
consolidated statements of operations, our pro

forma net income under SFAS No. 123 would have been the same as actual net
income.

    In November  2002, the FASB  issued FIN 45,  "Guarantor's Accounting  and
Disclosure Requirements for Guarantees, Including Indirect Guarantees of
Indebtedness of Others." FIN 45 clarifies the requirements for a guarantor's
accounting for and disclosures of certain guarantees issued and outstanding. The
provisions of FIN 45 apply to guarantee contracts that contingently require the
guarantor to make payments (in cash, financial instruments, other assets, shares
of stock or provision of services) to the guaranteed party for guarantees such
as a financial standby letter of credit, a market value guarantee on either a
financial or nonfinancial asset owned by the guaranteed party and a guarantee of
the collection of the scheduled contractual cash flows from financial assets
held by a special-purpose entity. FIN 45 also applies to indemnification
contracts and indirect guarantees of indebtedness of others. The requirements of
FIN 45 for the initial recognition and measurement of the liability for a
guarantor's obligations are to be applied only on a prospective basis to
guarantees issued or modified after December 31, 2002. We currently do not have
any guarantees, indemnification contracts or indirect guarantees of indebtedness
of others that would be subject to the initial recognition and measurement
provisions of FIN 45. Our 10 1/4% Senior Subordinated Notes due 2011 that were
issued in November 2001 are guaranteed by all of our domestic subsidiaries,
other than certain immaterial subsidiaries and our accounts receivable financing
subsidiary.

     In January  2003, the FASB  issued FIN 46,  "Consolidation of  Variable
Interest Entities." In accordance with FIN 46, a variable interest entity will
be consolidated if either the total equity investment at risk is not sufficient
to permit the entity to finance its activities without additional subordinated
financial support from other parties, or as a group, the holders of the equity
investment at risk lack any one of the following three characteristics of a
controlling financial interest: (1) the direct or indirect ability to make
decisions about an entity's activities; (2) the obligation to absorb the
expected losses of the entity if they occur; (3) the right to receive the
expected residual returns of the entity if they occur. All companies with
variable interests in variable interest entities created after January 31, 2003
shall apply the provisions of FIN 46 immediately. A public entity with a
variable interest in a variable interest entity created before February 1, 2003
shall apply the provisions of FIN 46 to that entity no later than the beginning
of the first interim or annual reporting period ending after December 15, 2003,
if such entity has not issued financial statements reporting that variable
interest entity in accordance with FIN 46. We do not have an interest in a
variable interest entity. Therefore, the adoption of FIN 46 does not currently
have an impact on our consolidated financial statements.

     In April 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133
on Derivative Instruments and Hedging Activities." SFAS No. 149 amends and
clarifies financial accounting and reporting for derivative instruments and
hedging activities under SFAS No. 133. SFAS No. 149 is effective for contracts
entered into or modified after June 30, 2003 and for hedging relationships
designated after June 30, 2003. The adoption of SFAS No. 149 will not have an
immediate impact on our consolidated financial statements.

               ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES
                              ABOUT MARKET RISK

     Reference is made to Management's Discussion and Analysis of Financial
Condition and Results of Operations in our Annual Report on Form 10-K for the
fiscal year ended December 31, 2002, for a discussion of "Market-Sensitive
Instruments and Risk Management." At December 31, 2002 and September 28, 2003,
there were no equity-related financial instruments employed by us to reduce
market risk.


                         ITEM 4. CONTROLS AND PROCEDURES

     Disclosure Controls  and Procedures:  Our management, with  the
participation of the Chief Executive Officer and Chief Financial Officer,
conducted an evaluation of the effectiveness of our disclosure controls and
procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of the end
of the period covered by this report. Based on this evaluation, the Chief
Executive Officer and Chief Financial Officer have concluded that, as of the end
of such period, our disclosure controls and procedures are effective in
recording, processing, summarizing and reporting, on a timely basis, information
required to be disclosed by us in the reports filed, furnished or submitted
under the Exchange Act.

     Internal Control  Over Financial Reporting:  There have  not been  any
changes in our internal control over financial reporting during the fiscal
quarter to which this report relates that have materially affected, or are
reasonably likely to materially affect, our internal control over financial
reporting.
