                    GENERAL CHEMICAL INDUSTRIAL PRODUCTS INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 2000
                             (DOLLARS IN THOUSANDS)
                                   (UNAUDITED)


NOTE 1 - BASIS OF PRESENTATION

         General Chemical Industrial Products Inc. (the "Company" or "GCIP") is
a leading North American supplier of soda ash and calcium chloride to a broad
range of industrial and municipal customers. The primary end markets for soda
ash include glass production, sodium-based chemicals, powdered detergents, water
treatment and other industrial end uses. Calcium chloride is mainly used for
dust control and roadbed stabilization during the summer and melting ice during
the winter.

         The Company is a wholly-owned subsidiary of The General Chemical
Group Inc ("GCG"). The Company was formed on April 30, 1999 as part of the
separation by GCG of its Manufacturing and Performance Products business from
its soda ash and calcium chloride business through a distribution of stock of
GenTek Inc. ("GenTek") to stockholders of GCG (the "Spinoff"). In connection
with the Spinoff, GCG transferred its soda ash and calcium chloride business
to GCIP and transferred its Manufacturing and Performance Products business to
a wholly-owned subsidiary, GenTek and distributed the stock of GenTek to
shareholders of GCG. On April 30, 1999, GCG and GenTek became separate
publicly-traded companies on the New York Stock Exchange. GCG continues to trade
using the GCG symbol. GCG owns and operates the Company, and GenTek owns and
operates the businesses comprising the Manufacturing and Performance Products
segments.

         These unaudited financial statements have been prepared pursuant to the
rules and regulations of the Securities and Exchange Commission. The financial
statements do not include certain information and footnotes required by
generally accepted accounting principles. In the opinion of management, all
adjustments (consisting only of normal recurring adjustments) considered
necessary for a fair presentation have been included. Operating results for the
six months ended June 30, 2000 are not necessarily indicative of the results
that may be expected for the year ending December 31, 2000. The Company's
financial statements should be read in conjunction with the financial statements
and the notes thereto for the year ended December 31, 1999 included in the Form
10-K.

         In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin: No. 101 - Revenue Recognition in Financial Statements
("SAB 101"), which provides guidance related to revenue recognition based on
interpretation and practices followed by the SEC. SAB 101 is effective for the
Company during the fourth fiscal quarter of the current year. The Company does
not expect the adoption of SAB 101 to have a material effect on the Company's
results of operations or financial condition or cash flows.

         Certain prior-period amounts have been reclassified to conform with the
current-year presentation.

NOTE 2 - COMPREHENSIVE INCOME (LOSS)

         Total comprehensive income (loss) is comprised of net income (loss) and
foreign currency translation gains and (losses). Total comprehensive income
(loss) for the six months ended June 30, 1999 and 2000 was $3,301 and $(1,289),
respectively.

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

June 30, 2000 Compared with December 31, 1999


Financial Condition

         Cash and cash equivalents were $17.3 million at June 30, 2000 compared
with $24.7 million at December 31, 1999. During the first six months of 2000,
the Company used cash flow from operating activities of $1.2 million, and used
cash of $6.3 million for capital expenditures.

         The Company had working capital of $61.5 million at June 30, 2000 as
compared with $59.5 million at December 31, 1999. The increase in working
capital principally reflects higher receivables and other current assets
partially offset by lower cash and inventory balances.

Results of Operations

June 30, 2000 Compared with December 31, 1999

         Net revenues for the three and six month periods ended June 30, 2000
decreased 4.9 percent and 8.1 percent to $65.8 million and $120.0 million,
respectively, from $69.2 million and $130.6 million for the comparable prior
year periods. Net revenues were negatively affected by lower calcium chloride
volumes due to warm winter weather and wet spring weather as well as lower soda
ash prices.

         Gross profit for the three month period ended June 30, 2000 decreased
$6.0 million to $9.2 million from $15.2 million for the comparable prior year
period. Gross profit as a percentage of net revenues for the three-month period
ended June 30, 2000 decreased to 14.0 percent from 22.0 percent for the same
period in 1999. Gross profit for the six- month period ended June 30, 2000
decreased $7.9 million to $17.5 million from $25.4 million for the comparable
prior year period. Gross profit as a percentage of net revenues for the
six-month period ended June 30, 2000 decreased to 14.6 percent from 19.5 percent
for the same period in 1999. These decreases were primarily due to the
above-mentioned decrease in net revenues as well as higher energy costs.

         Selling, general and administrative expense decreased $2.2 million and
$2.0 million for the three and six month periods ended June 30, 2000 as compared
to the prior period principally due to the $1.9 million one-time charge related
to the Spinoff in the second quarter of 1999. Selling, general and
administrative as a percentage of net revenues for the three and six month
period ended June 30, 2000 and 1999 decreased to 6.2 percent from 9.0 percent
and to 6.9 percent from 7.9 percent primarily due to the above-mentioned
one-time charge.

         Interest expense for the three and six month periods ended June 30,
2000 was $3.9 million and $7.8 million, which was $0.5 million and $1.7 million
higher, respectively, than the comparable prior period levels as a result of the
issuance of the Senior Subordinated Notes and borrowings under the Credit
Facility.

         Minority interest for the three and six month periods ended June 30,
2000 was $2.4 million and $5.4 million, respectively, versus $2.9 million and
$5.5 million for the same period in 1999. The decreases in both periods reflect
lower earnings due to lower soda ash pricing of General Chemical (Soda Ash)
Partners.

         Net income (loss) was $0.2 million and ($1.1) million for the three and
six-month periods ended June 30, 2000, respectively, versus net income of $2.3
million and $3.3 million for the comparable prior year periods, for the
foregoing reasons, net of available income tax benefits.

QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

         The Company does not expect to enter into financial instruments for
trading purposes. The Company anticipates periodically entering into interest
rate swap agreements to effectively convert all or a portion of its
floating-rate debt to fixed-rate debt in order to reduce its exposure to
movements in interest rates. Such agreements would involve the exchange of fixed
and floating interest rate payments over the life of the agreement without the
exchange of the underlying principal amounts. The Company also anticipates
periodically entering into currency agreements to partially reduce its exposure
to movements in currency exchange rates. Swap agreements will only be entered
into with strong creditworthy parties.
