                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

                FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 1998
                             (DOLLARS IN THOUSANDS)
                                   (UNAUDITED)

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

        The accompanying unaudited consolidated financial statements include the
accounts of The General Chemical Group Inc. and its subsidiaries (the
"Company"). These unaudited financial statements have been prepared by the
Company 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 of normal recurring adjustments)
considered necessary for a fair presentation have been included. Operating
results for the six months ended June 30, 1998 are not necessarily indicative of
the results that may be expected for the year ending December 31, 1998. The
Company's financial statements should be read in conjunction with the financial
statements and the notes thereto included in the Company's Annual Report on Form
10-K for the year ended December 31, 1997.

        In 1997, The Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" ("FAS
130") which the Company adopted for both interim and fiscal years beginning
after December 31, 1997. FAS 130 requires the reporting and display of
comprehensive income and its components. The Company's foreign currency
translation adjustments, which were previously reported as a separate component
of equity, are now included in Accumulated other comprehensive income within the
equity section of the Consolidated Balance Sheets. Comprehensive income for the
three and six months ended June 30, 1997 was $17,279 and $28,929, respectively.
Comprehensive income for the three and six months ended June 30, 1998 was
$11,119 and $20,766, respectively.

        In June 1998, The Financial Accounting Standards Board issued 
Statement of Financial Accounting Standards No. 133, 'Accounting for Derivative
Instruments and Hedging Activities' ('FAS 133'). FAS 133 requires that all 
derivative instruments be measured at fair value and recognized in the balance
sheet as either assets or liabilities. The Company is currently evaluating the
impact FAS 133 will have on its consolidated financial statements.

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

NOTE 2 - RELATED PARTY TRANSACTIONS

Inc. (a management and advisory company which is controlled by a stockholder of

                                   (UNAUDITED)

        The acquisitions are being accounted for under the purchase method,
and accordingly, the net assets and results of operations are included in the
consolidated financial statements from the date of acquisition, based on
valuation information available to the Company, which is subject to change as
such information is finalized. The excess of purchase price over the estimated
fair values of the tangible assets acquired is being treated as goodwill.
Goodwill is being amortized on a straight line basis over a period of 25 years.
The acquisitions did not have a material pro forma impact on consolidated
earnings.

superior courts of California (Contra Costa and San Francisco Counties) and in
federal court (United States District Court for the Northern District of
California). All state court cases were coordinated before a coordination trial
judge (In Re GCC Richmond Works Cases, JCCP No. 2906) and the federal court
cases were stayed until completion of the state court cases.

        After several months of negotiation under the supervision of a
settlement master, the Company and a court-approved plaintiffs' management
committee executed a comprehensive settlement agreement which resolved the
claims of approximately 95 percent of the claimants who filed lawsuits arising
out of the July 26th incident, including the federal court cases. After a final
settlement approval hearing on October 27, 1995, the coordination trial judge
approved the settlement on November 22, 1995. Pursuant to the terms of the
settlement agreement, the Company, with funds to be provided by its insurers
pursuant to the terms of its insurance policies, has agreed to make available a
maximum of $180,000 to implement the settlement. In addition, the settlement
agreement provides, among other things, that while claimants may Aopt out@ of
the compensatory damages portion of the settlement and pursue their own cases
separate and apart from the class settlement mechanism, they have no right to
opt out of the punitive damages portion of the settlement. Consequently, under
the terms of the settlement, no party may seek punitive damages from the Company
outside of those provided by the settlement.

        Notices of appeal of all or portions of the settlement approved by the
court were filed by five law firms representing approximately 2,750 claimants,
with approximately 2,700 of these claimants represented by the same law firm.
Virtually all of these claimants have not specified the amount of their claims
in court documents, although the Company believes that their alleged injuries
are no different in nature or extent than those alleged by the settling
claimants. On May 8, 1996, the California Court of Appeals dismissed each of the
appeals that had been filed challenging the trial court's approval of the class
action settlement. The Court of Appeals dismissed the appeal relating to the
trial court's rulings on plaintiffs' attorney's fees on the ground that the
appealing attorneys lacked standing to appeal. The Court of Appeals also
dismissed each of the other pending appeals, ruling that the trial court's
orders and rulings approving the settlement were not presently appealable, if at
all, by the appealing claimants since they had all elected to opt out of the
settlement. The appealing attorneys and some of the appealing claimants then
filed a petition for review with the California Supreme Court which, on August
15, 1996, elected not to review the Court of Appeals' decision.

                         THE GENERAL CHEMICAL GROUP INC.
          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS - (CONCLUDED)

                FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 1998
                             (DOLLARS IN THOUSANDS)
                                   (UNAUDITED)

        On March 11, 1997, the coordination judge dismissed the material claims
of 1,269 of the approximately 2,750 opt-out claimants, primarily on the grounds
that they had failed to comply with previous pre-trial orders. On April 8, 1997,
the California Court of Appeals denied a petition for review of the dismissals
filed by attorneys for the dismissed opt-out claimants, and on June 8, 1997, the
California Supreme Court denied the same attorneys' petition for review of the
California Court of Appeals' denial of their prior petition. On March 20, 1998,
the coordination judge dismissed the material claims of an additional 167 of the
opt-out claimants. As of June 30, 1998, as a result of these dismissals and
various settlements, there are approximately 1,000 opt-out claimants remaining.

         It is possible that one or more of the appealing claimants, once their
opt-out cases are finally litigated through trial, may attempt to refile all or
a portion of the appeals that were dismissed by the Court of Appeals. While
there can be no assurances regarding how an appellate court might rule in the
event of such a refiling, the Company believes that the settlement will be
upheld on appeal. If the settlement is upheld on appeal, the Company believes
that any further liability in excess of the amounts made available under the
settlement agreement will not exceed the available insurance coverage, if at
all, by an amount that could be material to its financial condition or results
of operations. In the event of a reversal or modification of the settlement on
appeal, with respect to lawsuits by any then remaining claimants (opt-outs and
settling claimants who have not signed releases) the Company believes that,
whether or not it elects to terminate the settlement in the event it is reversed
or modified on appeal, it will have adequate resources from its available
insurance coverage to vigorously defend these lawsuits through their ultimate
conclusion, whether by trial or settlement. However, in the event the settlement
is overturned or modified on appeal, there can be no assurance that the
Company's ultimate liability resulting from the July 26, 1993 incident would not
exceed the available insurance coverage by an amount which could be material to
its financial condition or results of operations, nor is the Company able to
estimate or predict a range of what such ultimate liability might be, if any.

         The Company has insurance coverage relating to this incident which
totals $200,000. The first two layers of coverage total $25,000 with a sublimit
of $12,000 applicable to the July 26, 1993 incident, and the Company also has
excess insurance policies of $175,000 over the first two layers. The Company
reached an agreement with the carrier for the first two layers whereby the
carrier paid the Company $16,000 in settlement of all claims the Company had
against that carrier. In the third quarter of 1994, the Company recorded a
$9,000 charge to earnings for costs which the Company incurred related to this
matter. The Company's excess insurance policies, which are written by two
Bermuda-based insurers, provide coverage for compensatory as well as punitive
damages. Both insurers have executed agreements with the Company confirming
their respective commitments to fund the settlement as required by their
insurance policies with the Company and as described in the settlement
agreement. In addition, these same insurers currently continue to provide
substantially the same insurance coverage to the Company.

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

June 30, 1998 Compared with December 31, 1997

Financial Condition

         Cash and cash equivalents were $38.2 million at June 30, 1998 as
compared with $21.8 million at December 31, 1997. During the first six months of
1998 the Company generated cash flow from operating activities of $32.7 million,
and received net proceeds from debt of $91.4 million, which was used to finance
acquisitions and capital expenditures of $83.2 million and $23.4 million,
respectively.

         The Company had working capital of $54.4 million at June 30, 1998 as
compared with $50.4 million at December 31, 1997. This increase in working
capital primarily reflects higher cash, accounts receivable and inventory offset
by higher current portion of long-term debt.

         During the second quarter of 1998, the Company completed a $600 million
refinancing plan to improve financial flexibility, simplify the capital
structure, support future growth efforts, refinance certain existing debt and
provide substantial funds for new acquisitions.

         On April 1, 1998, the previously-announced acquisition of Reheis, Inc.
("Reheis") by a subsidiary of the Company was closed. Funding for this
transaction was provided with existing cash and borrowings from the Company's
revolving credit facility.

Results of Operations

        Net revenues for the three and six month periods ended June 30, 1998
increased 14 percent and 11 percent to $188.1 million and $349.5 million,
respectively, from $165.0 million and $314.5 million for the comparable periods
in 1997. This increase is due to higher sales in the Chemical and Manufacturing
Segments. The increase in the Manufacturing Segment primarily reflects higher
volumes. The increase in the Chemical Segment is due primarily to sales of
Peridot Holdings, Inc. ("Peridot") and Reheis, Inc. which were acquired on July
1, 1997 and April 1, 1998, respectively, offset by weaker pricing for Industrial
Chemicals and lower export soda ash volumes to Asia.

        Gross profit for the three month periods ended June 30, 1998 decreased 3
percent to $53.1 million from $54.6 million for the same period in 1997. Gross
profit for the six month period ended June 30, 1998 decreased 5 percent to $95.1
million from $99.8 million for the same period in 1997. These decreases were
primarily related to the lower pricing for Industrial Chemicals partially offset
by acquisition related sales increases and higher Manufacturing Segment sales.

        Gross profit as a percentage of sales for the three months ended June
30, 1998 decreased to 28 percent from 33 percent for the same period in 1997.
Gross profit as a percentage of sales for the six months ended June 30, 1998
decreased to 27 percent from 32 percent for the same period in 1997. These
decreases are primarily due to the lower pricing for Industrial Chemicals.

        Selling, general and administrative expense compared with the prior year
increased $2.6 million and $3.4 million, respectively, for the three and six
month periods ended June 30, 1998. This increase is due primarily to the
abovementioned acquisitions of Peridot and Reheis.

        Interest expense for the three and six month periods ended June 30, 1998
was $6.8 million and $12.4 million, which was $1.7 million and $2.0 million
higher, respectively, than the comparable prior year levels as a result of
higher outstanding debt balances.

                                      -8-

<PAGE>


        Interest income for the three and six month periods ended June 30, 1998
was $.2 million and $.7 million, respectively, versus $.6 million and $1.3
million for the same periods in 1997 as a result of lower average cash balances.

        The foreign currency transaction loss for the three and six month
periods ended June 30, 1998 was $.6 million and $.4 million, respectively. There
was no foreign currency transaction (gain) loss for the three months ended June
30, 1997. The foreign currency loss for the six months ended June 30, 1997 was
$.4 million. These amounts are principally due to the impact of exchange rate
fluctuations on the Company's Canadian subsidiary.

        Minority interest for the three and six month periods ended June 30,
1998 was $3.7 million and $8.1 million, respectively, versus $6.1 million and
$12.3 million for the comparable periods in 1997. The decrease in both periods
reflect lower earnings due to lower soda ash pricing of General Chemical (Soda
Ash) Partners.

        Net income was $11.0 million and $20.9 million for the three and six
month periods ended June 30, 1998, respectively, versus $17.3 million and $29.0
million for the comparable periods in 1997, for the foregoing reasons and a $3.7
million extraordinary item related to the early extinguishment of debt recorded
during the second quarter of 1998.

                           PART II. OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

        The following developments have occurred with respect to this matter
since the filing of the Company's Quarterly Report on Form 10-Q for the period
ended March 31, 1998:

        In April of 1998, approximately 40 employees (and their respective
spouses) of the Sun Company, Inc. refinery in Marcus Hook, Pennsylvania, filed
lawsuits in the Court of Common Pleas, Delaware County, Pennsylvania, against
the Company, alleging that sulfur dioxide (SO2) and sulfur trioxide (SO3)
releases from the Company's Delaware Valley facility caused various respiratory
and pulmonary injuries. Unspecified damages in excess of $50,000 for each
plaintiff are sought. The Company has answered the complaints and will
vigorously defend itself in this matter. The Company believes that its available
insurance provides adequate coverage in the event of an adverse result in this
matter and that, based on currently-available information, this matter will not
have a material adverse effect on the Company's financial condition or results
of operations.
