                         THE GENERAL CHEMICAL GROUP INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
             FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30, 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 businesses from its
Industrial Chemicals business through a distribution of stock of GenTek Inc.
("GenTek") to stockholders of GCG (the "Spinoff"). Pursuant to the Spinoff, GCG
transferred the Manufacturing and Performance Products businesses to a
wholly-owned subsidiary, GenTek Inc. and distributed the stock of GenTek to
shareholders of GCG. As a result of the Spinoff, 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 business,
and GenTek owns and operates the businesses comprising the Manufacturing and
Performance Products businesses.

         On March 18, 1999, GCG filed with the Securities and Exchange
Commission 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-K are
incorporated herein by reference.

         The Spinoff was treated as a reverse spinoff 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 business. Included in selling, general and administrative
expense in the accompanying consolidated statement of operations for the nine
months ended September 30, 1999 are Spinoff related expenses of $1,900.

         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 nine
months ended September 30, 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 nine
months ended September 30, 1998 and 1999 was $8,634 and $4,369, respectively.

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 September 30, 1998 and 1999 options to purchase 60,000 shares and
1,674,500 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, 2008 and 2009, were still outstanding at September 30, 1999.

         On April 30, 1999, in connection with the Spinoff, the Company's
subsidiary, General Chemical Industrial Products Inc. ("GCIP"), and GCIP's
Canadian subsidiary, General Chemical Canada Ltd., entered into an $85 million
revolving credit facility ("Credit Facility") with certain lenders party
thereto, The Chase Manhattan Bank, as Administrative Agent, The Chase Manhattan
Bank of Canada, as Canadian Administrative Agent, The Bank of Nova Scotia, as
Syndication Agent, and The First National Bank of Chicago as Documentation
Agent. Of this amount, up to $60 million is available for borrowing by the
Canadian subsidiary. In addition, on April 30, 1999, GCIP issued and sold $100
million aggregate principal amount of 10 5/8% Senior Subordinated Notes due
2009.

                                   (UNAUDITED)

The Company applied the proceeds of its initial borrowing under the Credit
Facility and a portion of the proceeds of the offering of its Senior
Subordinated Notes to repay approximately $122 million of pre-Spinoff debt. On
November 9, 1999, GCIP completed its exchange offer pursuant to which all of
GCIP's unregistered 10 5/8% Senior Subordinated Notes due 2009 (issued on April
30, 1999) were exchanged for registered 10 5/8% Senior Subordinated Notes due
2009 that are identical to the terms of the unregistered notes. The Securities
and Exchange Commission declared effective GCIP's Registration Statement on Form
S-4 with respect to such registered notes on October 6, 1999.

         The Senior Subordinated Notes are unsecured while the $85 million
Credit Facility is secured by 100% of the capital stock of GCIP, 100% of the
owned capital stock of, and guarantees from, the direct and indirect domestic
subsidiaries of GCIP, 65% of certain foreign subsidiaries of GCIP and
substantially all of the other assets of GCIP. In addition, the portion of the
Credit Facility available to GCIP's Canadian subsidiary is secured by
substantially all of the assets of the GCIP's Canadian subsidiary. The Senior
Subordinated Notes and the Credit Facility contain certain covenants with
respect to additional indebtedness, and preferred stock by subsidiaries,
restricted payments, transactions with affiliates, liens, dividends and other
payment instructions affecting subsidiaries, consolidations, mergers, the sale
of assets and financial tests.

NOTE 6 - 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 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.

NOTE 7 - RELATED PARTY TRANSACTIONS

MANAGEMENT AGREEMENT

         GCG is party to a management agreement with Latona Associates
("Latona") (which is controlled by a shareholder of GCG) pursuant to which
Latona provides GCG, subject to the direction and supervision of the Board of
Directors of the Company (i) senior corporate functions (including supervision
of the Company's finance, legal and executive recruitment functions) and (ii)
services in connection with acquisition candidates and acquiring financing for
such transactions for a fee. In connection with the Spinoff, Latona agreed to
provide its services separately to GCG and GenTek. GCG's share of this
management fee is $855 and $1,113 for the nine months ended September 30, 1998
and 1999, respectively.

TRANSITION SUPPORT AGREEMENT

         GCG and GenTek have entered into various transition agreements that
provide mechanisms for an orderly transition after the Spinoff. For the period
from April 30, 1999 to September 30, 1999, GenTek charged GCG $1,534 related to
these transition agreements.

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

Financial Condition

September 30, 1999 Compared with December 31, 1998

         Cash and cash equivalents were $35.0 million at September 30, 1999
compared with $1.1 million at December 31, 1998. During the first nine months of
1999, the Company generated cash flow from operating activities of $25.5 million
and received net proceeds from debt of $145.4 million, and used cash of $14.3
million for capital expenditures and transferred $122.5 million to GenTek for
repayment of preSpinoff debt.

         The Company had working capital of $ 64.9 million at September 30, 1999
as compared with $39.9 million at December 31, 1998. This increase in working
capital principally reflects higher cash balances due to the proceeds from debt
partially offset by the transfer to GenTek for repayment of preSpinoff debt.

Results of Operations

September 30, 1999 Compared with September 30, 1998

         Net revenues for the three month period ended September 30, 1999 were
essentially unchanged at $64.1 million as compared to $64.2 million in the
comparable prior period. Net revenues were negatively affected by lower soda ash
prices, partially offset by higher sales volume of soda ash. Net revenues for
the nine month period ended September 30, 1999 decreased 1% to $194.8 million
from $197.6 million for the comparable period in 1998. This decrease is due to
lower soda ash prices partially offset by higher sales of calcium chloride and
soda ash.

         Gross profit for the three month period ended September 30, 1999
decreased $2.1 million to $12.4 million from $14.5 million for the comparable
prior year period. Gross profit as a percentage of net revenues for the three
month period ended September 30, 1999 decreased to 19 percent from 23 percent
for the same period in 1998. Gross profit for the nine month period ended
September 30, 1999 decreased $7.1 million to $37.9 million from $45.0 million
for the comparable prior year period. Gross profit as a percentage of net
revenues for the nine month period ended September 30, 1999 decreased to 19
percent from 23 percent for the same period in 1998. These decreases were
primarily due to the above-mentioned lower soda ash prices.

         Selling, general and administrative expense increased $0.1 million and
$2.3 million for the three and nine month periods ended September 30, 1999 as
compared to the prior period principally due to the $1.9 million one-time charge
related to legal, audit, actuarial and other Spinoff related charges in the
second quarter. Selling, general and administrative expense as a percentage of
net revenues for the nine month period ended September 30, 1999 and 1998
increased to 8 percent from 6 percent for the same period in 1998 primarily due
to the above-mentioned one-time charge.

         Interest expense for the three and nine month periods ended September
30, 1999 was $3.8 million and $9.8 million, which was $0.9 million and $1.0
million higher, respectively, than the comparable prior period level as a result
of the issuance of the Senior Subordinated Notes and borrowings under the Credit
Facility.

         Interest income for the three and nine month periods ended September
30, 1999 was $0.4 million and $0.9 million, respectively, versus $0.3 million
and $0.6 million for the same periods in 1998 as a result of the net proceeds
from the issuance of the Senior Subordinated Notes.

         Minority interest for the three and nine month periods ended September
30, 1999 was $3.5 million and $9.0 million, respectively, versus $3.6 million
and $11.8 million for the same periods in 1998. The decreases in both periods
reflect lower earnings due to weaker soda ash pricing of General Chemical (Soda
Ash) Partners.


                                      -10-




<PAGE>


         Net income was $1.1 million and $4.4 million for the three and nine
month periods ended September 30, 1999, respectively, versus $2.9 million and
$8.8 million for the comparable periods in 1998, for the foregoing reasons.

YEAR 2000 ISSUE

         Following the Spinoff, GenTek provides us with management information
systems and related functions, including personnel, hardware and software,
through December 31, 2001 on a service contract basis. During this period, as
provided in the transition support agreement, GenTek will provide us services
related to the remediation of the Year 2000 problem for our business. A Year
2000 problem can occur where date-sensitive software uses two digit year date
fields, sorting the Year 2000 ("00") before the 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, including non-information technology
equipment and systems. The failure of such systems to properly recognize dates
after December 31, 1999 could result in data corruption and processing errors.

         The transition support agreement provides that generally GenTek will
not be liable to us for any costs, losses, damages or claims related to any Year
2000 services provided by it under the transition support agreement, other than
for gross negligence or willful misconduct. We intend to work with GenTek on the
separation of management information systems functions after resolution of Year
2000 problems. We anticipate that we will recruit our own staff for this work
during 2001 and that by approximately December 2001 a separation of our and
GenTek's functions will be completed.

         We completed an assessment of our business' Year 2000 compliance status
in early 1997. This assessment found that the majority of our systems were Year
2000 compliant. The assessment revealed some minor problems with the maintenance
management and order processing systems and several process control systems.
Immediately thereafter, we began a remediation program to correct these material
systems. We did not entirely replace any systems necessary to the operation of
our facilities.

         We completed the majority of our remediation efforts in 1998 and
completed the remaining work in the third quarter of 1999. The following
schedule describes our progress by phase and the final completion date with
respect to our material systems.

</TABLE>

         As of September 30, 1999, a total of approximately $1.0 million had
been spent in connection with the Year 2000 program for our business and
GenTek's business. We believe that as of August 31, 1999 all material systems
were Year 2000 compliant and, therefore, we expect no additional expenditures
relating to the material systems of our business. We have used and will continue
to use funds from operations to bring our systems into Year 2000 compliance. In
the event that material systems of our business do not prove to be Year 2000
compliant, we may experience reductions or interruptions in operations which
could have a material adverse effect on our results of operations.

         We have also evaluated critical vendors, suppliers and service
providers for Year 2000 compliance, including the railroad and trucking
companies we use to ship our products. This evaluation included sending out
letters with questionnaires to all key suppliers together with follow-up
telephone calls and additional

                                      -11-




<PAGE>

correspondence to complete the evaluation. Based upon the information we
obtained from those suppliers, we do not anticipate that the failure of any
of our key suppliers will have a material impact to our business operations.
However, the process of evaluating the Year 2000 compliance of material third
parties is continually ongoing and, therefore, we can make no guaranty or
warranty as to such third parties' future compliance status or its potential
effect on us.

         We have developed preliminary contingency plans to deal with three
worst case Year 2000 scenarios:

(1) We cannot obtain sufficient critical raw materials over an extended period
    of time;

(2) Intermittent power outages occur at our facilities; and/or

(3) Railcars become difficult to obtain due to congestion in the railcar system.

         Our preliminary contingency plan consists of the following:

         First, to insure that our facilities will have sufficient raw
materials, we expect to build up critical supplies and develop alternate sources
of raw material suppliers as we approach year-end. This has been a regular
practice at both our facilities due to the harsh winter climate. Second, we
believe that as both our facilities have capacity to generate electrical power,
they may be able to sustain operations through short-term power outages. Lastly,
we expect to build inventories of railcars at our rail sidings and arrange to
use truck carriers to deliver products although any such arrangements are likely
only to address short-term congestion in the railcar system.

         There can be no assurance, however, that we will be able to
successfully carry out our contingency plans, that our contingency plans will
adequately address the above worst case Year 2000 scenarios, or that these
contingency plans will address every Year 2000 problem resulting from the
failure of our suppliers to be Year 2000 compliant. As a result, we are likely
to experience interruptions, slowdowns or increased costs in our business if our
suppliers fail to be Year 2000 compliant.

ITEM 3.  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.
