                         THE GENERAL CHEMICAL GROUP INC.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                      FOR THE QUARTER ENDED MARCH 31, 1999
                             (DOLLARS IN THOUSANDS)
                                   (UNAUDITED)

NOTE 1 - BASIS OF PRESENTATION

         On April 30, 1999, The General Chemical Group Inc. ("GCG") completed
the separation of its Manufacturing and Performance Products Segments from its
Industrial Chemicals Segment through a distribution of stock of GenTek Inc. to
stockholders of GCG (the "Spinoff"). In connection with the Spinoff, GCG
transferred the Manufacturing and Performance Products Segments to a
wholly-owned subsidiary, GenTek Inc. ("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 Industrial
Chemicals Segment, and GenTek owns and operates the businesses comprising the
Manufacturing and Performance Products Segments.

         On March 18, 1999, GCG filed with the Securities and Exchange
Commissions a report on Form 8-K with respect to the Spinoff, and on April 8,
1999 GenTek Inc. filed with the Securities and Exchange Commission an
Amendment No. 2 to Registration Statement on Form 10 to register its common
stock under the Securities Exchange Act of 1934. Both such Form 8-K and Form 10
are incorporated herein by reference.

         The Spinoff was treated as a reverse spin-off for financial statement
purposes because a greater proportion of GCG's assets and operations are held by
GenTek after the Spinoff. Therefore, the Spinoff has been reflected, for
financial statement presentation, as if GCG is a new company consisting of the
Industrial Chemicals Segment.

         The accompanying unaudited consolidated financial statements include
the accounts of GCG and its subsidiaries (collectively, 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, 1999 are not necessarily indicative of the results that
may be expected for the year ending December 31, 1999. The Company's financial
statements should be read in conjunction with the financial statements and the
notes thereto for the Industrial Chemicals Business for the year ended December
31, 1998 included in the Form 8-K and the Form 10.

         For the purpose of governing certain ongoing relationships between the
Company and GenTek after the Spinoff and to provide mechanisms for an orderly
transition, the Company and GenTek have entered into various agreements.
Management believes that the agreements are comparable to those which would have
been reached in arm's length negotiations with unaffiliated parties.

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

NOTE 2 - COMPREHENSIVE INCOME

         Total comprehensive income is comprised of net income and foreign
currency translation gains and losses. Total comprehensive income for the three
months ended March 31, 1998 and 1999 was $1,901 and $963, respectively.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)
                      FOR THE QUARTER ENDED MARCH 31, 1999

                                   (UNAUDITED)

NOTE 3 - EARNINGS PER SHARE

         The computation of basic earnings per share is based on the weighted
average number of common shares and contingently issuable shares outstanding
during the period. The computation of diluted earnings per share assumes the
foregoing and, in addition, the exercise of all stock options and restricted
units, using the treasury stock method.

         The components of the denominator for basic earnings per common share
and diluted earnings per common share are reconciled as follows:

</TABLE>


         At March 31, 1998 and 1999 options to purchase 60,000 shares and
1,704,500 shares of common stock, respectively, were not included in the
computation of diluted earnings per common share because the exercise price was
greater than the average market price of the common shares. The options, which
expire during 2007 and 2008, were still outstanding at March 31, 1999.

NOTE 5 - DIVIDENDS

         On March 10, 1999, GCG's Board of Directors declared a quarterly cash
dividend of $.05 per share, payable April 5, 1999, to shareholders of record on
March 24, 1999. As a consequence of the Spinoff, the Board of Directors of GCG
does not expect to pay dividends in the near future. The dividend policies of
GCG are subject to change and will be based on, among other factors, its 
operating results and financial requirements and the restrictions imposed by
its financing facilities.

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

March 31, 1999 Compared with December 31, 1998


Financial Condition

         Cash and cash equivalents were $1.2 million at March 31, 1999 compared
with $1.1 million at December 31, 1998. During the first three months of 1999,
the Company generated cash flow from operating activities of $12.1 million, and
used cash of $3.3 million for capital expenditures and transferred $8.4 million
to GenTek.

         The Company had working capital of $37.9 million at March 31, 1999 as
compared with $39.9 million at December 31, 1998. This decrease in working
capital principally reflects lower inventories.

Results of Operations

         Net revenues for the three month period ended March 31, 1999 were $61.5
million, versus $62.3 million for the comparable period in 1998. This decrease
is due to lower soda ash prices partially offset by higher calcium chloride
volumes.

         Gross profit for the three month period ended March 31, 1999 decreased
$3.0 million to $10.2 million from $13.2 million for the comparable prior year
period. Gross profit as a percentage of sales decreased 4 percent to 17 percent
for the three months ended March 31, 1999 versus 21 percent for the three month
period ended March 31, 1998 primarily due to the above-mentioned lower soda ash
prices.

         Selling, general and administrative expense as a percentage of net
revenues was 6 percent and 7 percent for the three months ended March 31, 1998
and 1999, respectively.

         Interest expense for the three month period ended March 31, 1999 was
$2.7 million, which was $.2 million lower than the
comparable prior year level.

         Interest income for the three month period ended March 31, 1999 was $.4
million, which was $.3 million higher than the comparable prior year level.

         Minority interest for the three month period ended March 31, 1999 was
$2.6 million compared with $4.4 million for the three month period ended March
31, 1998, reflecting lower earnings due to weaker soda ash pricing of General
Chemical (Soda Ash) Partners.

         Net income was $1.0 million for the three month period ended March 31,
1999, versus $1.9 million for the comparable period in 1998, for the foregoing
reasons.

YEAR 2000 ISSUE

         Following the Spinoff, GenTek provides GCG with MIS and
MIS-supported functions, including MIS personnel, hardware and software on a
service contract basis through approximately December 31, 2001. During this
period, GenTek provides to the Company the services related to the
remediation of the Year 2000 problem. A Year 2000 problem will occur where
date-sensitive software uses two digit year date fields, sorting the Year 2000
("00") before Year 1999 ("99"). The Year 2000 problem can arise in hardware,
software or any other equipment or process that uses embedded software or other
technology. The failure of such systems to properly recognize dates after
December 31, 1999 could result in data corruption and processing errors.

         The Company completed an assessment of its Year 2000 compliance status
in early 1997 and began work on its remediation program immediately thereafter.
GenTek, which is principally responsible for overseeing the MIS functions
through 2001, intends to continue the Year 2000 remediation program for both
GenTek and the Company and is expected to effect all conversion efforts needed
to prevent the potential impact of Year 2000 problems. The Company intends to
work on the separation of MIS functions after resolution of Year 2000 problems.
The Company anticipates that it will recruit its own MIS staff during 2001 and
that by approximately December, 2001 a separation of its MIS functions will be
completed.

         The remediation program has been structured to address its Systems. The
Company has spent approximately $1.0 million to replace or reprogram existing
Systems and complete the Year 2000 compliance program for the MIS functions
serving both GenTek and the Company. All material Systems are Year 2000
compliant as of March 31, 1999 and substantially all Systems will be Year 2000
compliant by December 31, 1999. In the event that material Systems are not Year
2000 compliant, the Company may experience reductions or interruptions in
operations which could have a material adverse effect on the Company's results
of operations.

         In addition, the Company is working with GenTek to determine the Year
2000 compliance status of its material vendors, suppliers and service providers,
including the railroad and trucking companies used to ship its products. Based
on currently available information, management does not anticipate any material
impact to the Company based on the failure of such third parties to be Year 2000
compliant. However, the process of evaluating the Year 2000 compliance status of
material third parties is continually ongoing and, therefore, no guaranty or
warranty can be made as to such third parties' future compliance status or its
potential effect on the Company. Management believes there exists a sufficient
number of suppliers of raw materials so that alternate sources will be available
if any supplier is unable to deliver raw materials due to the Year 2000 issue.
There can be no assurances, however, that such alternate sources will be able to
supply all the requirements in a timely manner or on terms comparable with those
of its current suppliers. If the railroads or trucking companies that ship the
Company's products fail to be Year 2000 compliant, the Company may not be able
to arrange alternative and timely means to ship its goods, which could lead to
interruptions or slowdowns in its business. The Company is preparing for the
possible use of alternative suppliers and means of transportation, possible
adjustment of raw material and product inventory levels and contingencies with
respect to potential energy source interruptions, all in an effort to minimize
the effects, if any, of Year 2000 related interruptions or slowdowns caused by
suppliers and transporters.

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.
