                         THE GENERAL CHEMICAL GROUP INC.
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

                      FOR THE QUARTER ENDED MARCH 31, 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 three months ended March 31, 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 months ended March 31, 1997 and 1998, was $11,650 and $9,647,
respectively.

NOTE 2 - RELATED PARTY TRANSACTIONS

Management Agreement

         The Company is party to a management agreement with Latona Associates
Inc. (a management and advisory company which is controlled by a stockholder of
the Company). Pursuant to the agreement, the Company was charged $1,460 and
$1,481 for the three months ended March 31, 1997 and 1998, respectively, for
corporate supervisory and administrative services and strategic advice and
guidance. The management agreement expires on December 31, 2004.

NOTE 3 - ACQUISITIONS

         On February 6, 1998, the Company's wholly owned subsidiary, Toledo
Technologies, Inc. acquired all of the outstanding stock of Sandco Automotive
Ltd. ("Sandco"), a manufacturer of engine parts for the North American
automobile industry and its aftermarket. Sandco is based in Waterdown, Ontario.
Funding for this transaction was provided with new borrowings. The acquisition
was 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 preliminary 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
net tangible assets acquired is being treated as goodwill. Goodwill is being
amortized on a straight line basis over a period of 25 years. The acquisition
did not have a material pro forma impact on consolidated earnings.

                                   (UNAUDITED)

         On April 1, 1998, the Company's wholly owned subsidiary General
Chemical Corporation ("GCC"), acquired all of the outstanding stock of Reheis
Inc. ("Reheis"). Reheis is headquartered in New Jersey and is the world's
leading producer and supplier of the active chemical ingredients in
antiperspirants and over-the-counter antacids as well as a supplier of
pharmaceutical intermediates and other products. Funding for this transaction
was provided by existing cash and borrowings under GCC's revolving credit
facility. As of March 31, 1998, the Company placed approximately $84,500 in
escrow related to the pending acquisition of Reheis. Such amount is included in
other current assets. The acquisition will be accounted for under the purchase
method, and accordingly, the net assets and results of operations will be
included in the consolidated financial statements from the date of acquisition,
based on valuation information available to GCC, which is subject to change as
such information is finalized. The excess of purchase price over the estimated
fair values of the net tangible assets acquired will be treated as goodwill.
Goodwill will be amortized on a straight line basis over a period of 25 years.

NOTE 7 - COMMITMENTS AND CONTINGENCIES

         Richmond Works July 26, 1993 Incident. On July 26,1993 a pressure
relief device on a railroad tank car containing oleum that was being unloaded at
the Company's Richmond, California, facility, ruptured during the unloading
process, causing the release of a significant amount of sulfur trioxide.
Approximately 150 lawsuits seeking substantial amounts of damages were filed
against the Company on behalf of in excess of 60,000 claimants in municipal and
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 "opt 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.

         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.

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

                      FOR THE QUARTER ENDED MARCH 31, 1998
                             (DOLLARS IN THOUSANDS)
                                   (UNAUDITED)

         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.

March 31, 1998 Compared with December 31, 1997

Financial Condition

          Cash and cash equivalents were $20.5 million at March 31, 1998 as
compared with $21.8 million at December 31, 1997. During the first three months
of 1998 the Company generated cash flow from operating activities of $26.0
million, and used cash of $4.3 million for repayment of long-term debt and $9.6
million for capital expenditures.

          The Company had working capital of $19.4 million at March 31, 1998 as
compared with $50.4 million at December 31, 1997. This decrease in working
capital principally reflects the higher current portion of long-term debt,
partially offset by higher other current assets. The increase in the current
portion of long-term debt reflects the increase in borrowings related to the
Reheis acquisition and the maturity of the Company's U.S. Revolving Credit
Facility on March 31, 1999. The increase in other current assets represents an
escrow deposit related to the pending acquisition of Reheis. The Company has
commenced a $600 million bank financing to improve financial flexibility,
simplify the capital structure and support future growth efforts. This
transaction will refinance certain existing debt and provide substantial funds
for new acquisitions.

Results of Operations

         Net revenues for the three month period ended March 31, 1998 increased
8 percent to $161.5 million, from $149.6 million for the comparable period in
1997. This increase is due to higher sales in both the Manufacturing and
Chemical 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. which was acquired on July 1, 1997, offset by weaker
pricing of soda ash and calcium chloride.

         Gross profit for the three month period ended March 31, 1998 decreased
7 percent to $42.0 million from $45.2 million for the comparable prior year
period. Gross profit as a percentage of sales decreased 4 percent to 26 percent
for the three months ended March 31, 1998 versus 30 percent for the three month
period ended March 31, 1997 primarily due to lower pricing of soda ash and
calcium chloride and higher natural gas costs.

         Selling, general and administrative expense as a percentage of net
revenues was 10 percent for the three months ended March 31, 1997 and 1998.

         Interest expense for the three month period ended March 31, 1998 was
$5.6 million, which was $.3 million higher than the comparable prior year level
as a result of higher outstanding debt balances.

         Interest income for the three month period ended March 31, 1998 was $.4
million, which was $.3 million lower than the comparable prior year level as a
result of lower cash balances in 1998.

         The foreign currency transaction gain for the three month period ended
March 31, 1998 was $.2 million versus a loss of $(.5) million for the comparable
period in 1997, principally due to the impact of exchange rate fluctuations on
the Company's Canadian subsidiary.

         Minority interest for the three month period ended March 31, 1998 was
$4.4 million compared with $6.2 million for the three month period ended March
31,1997, reflecting lower earnings due to lower soda ash pricing of General
Chemical (Soda Ash) Partners.

         Net income was $9.9 million for the three month period ended March 31,
1998, versus $11.7 million for the comparable period in 1997, for the foregoing
reasons.

                           PART II. OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

         The following developments have occurred since the filing of the
Company's Annual Report on Form 10-K for the year ended December 31, 1997:

         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. As these lawsuits have only recently been served on the
Company, no investigation of the allegations has yet been performed. 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.
