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

NOTE 1 - BASIS OF PRESENTATION

     GenTek Inc.'s ("GenTek" or the "Company") manufacturing and performance
products businesses (the "GenTek Business") were formerly part of the businesses
of The General Chemical Group Inc. ("GCG"). GCG separated the GenTek Business
from GCG's soda ash and calcium chloride business (the "Industrial Chemicals
Business") through a spinoff (the "Spinoff"). GCG accomplished the Spinoff by
transferring the GenTek Business to GenTek, and distributing the common stock of
GenTek to GCG's shareholders. The Spinoff was completed on April 30, 1999 (the
"Spinoff Date").

     Since the Spinoff, GCG and GenTek have been two separate, stand-alone
companies; GenTek operates the GenTek Business, and GCG operates the Industrial
Chemicals Business. GenTek's common stock is listed on the New York Stock
Exchange (under the symbol "GK"). GCG's common stock is listed on the New York
Stock Exchange (under the symbol "GCG").

     The Spinoff has been treated as a reverse spinoff for financial statement
purposes because a greater proportion of GCG's assets and operations are being
held by GenTek. Therefore, the Spinoff has been reflected, for financial
statement presentation, as if GenTek formed a new company consisting of the
Industrial Chemicals Segment and distributed the stock of that company as a
dividend to GenTek's stockholders, with the assets and operations of the
Performance Products and Manufacturing Segments remaining with GenTek.
Accordingly, the GenTek financial statements reflect the financial position and
results of operations of the Performance Products and Manufacturing Segments as
continuing operations and the financial position and results of operations of
the Industrial Chemicals Business as discontinued operations.

     For the purpose of governing certain ongoing relationships between GCG and
GenTek after the Spinoff and to provide mechanisms for an orderly transition,
GCG 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.

     The accompanying unaudited consolidated financial statements have been
prepared by the Company pursuant to the rules and regulations of the Securities
and Exchange Commission (the "SEC"). 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 ended
December 31, 1999. These statements should be read in conjunction with the
Amendment No. 2 to the Registration Statement on Form 10 (file no. 001-14789) of
GenTek (the "Form 10") filed with the SEC under the Securities Exchange Act of
1934, which Form 10 is incorporated herein by reference.

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

NOTE 2 - DISCONTINUED OPERATIONS

     Discontinued operations represent the industrial chemical business of the
Company (see Note 1). An allocation of certain assets, liabilities and expenses
has been made related to discontinued operations. In the opinion of management,
expenses have been allocated to the discontinued operations in a reasonable and
consistent basis using management's estimate of services provided to the
discontinued business by the Company. General corporate overhead expenses have
not been allocated to discontinued operations. However, such allocations are not
necessarily indicative of the level of expenses which might have been incurred
had the industrial chemicals business been operating as a stand-alone entity
during the periods presented or expected to be incurred after the Spinoff.

NOTE 3 - 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 $9,732 and $9,214, respectively.

NOTE 4 - 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 also includes
the exercise of all stock options and restricted units, using the treasury stock
method.

     The shares outstanding used for basic 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.

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

NOTE 5 - ACQUISITIONS

     On February 6, 1998, the Company acquired for $6,999 all of the outstanding
stock of Sandco Automotive Ltd. ("Sandco"), a manufacturer of engine parts for
the North American automobile industry and its aftermarket. On April 1, 1998,
the Company acquired for $83,936 all of the outstanding stock of Reheis Inc.
("Reheis"), a 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. On February 23, 1999, the
Company acquired for $58,020 through a cash tender offer, Defiance Inc.
("Defiance"), a manufacturer of specialty antifriction bearings for the
transportation industry and a provider of vehicle testing services, tooling
design and preproduction dies and components primarily for the automotive
industry. On April 6, 1999, the Company acquired for approximately $220,000 Noma
Industries Limited ("Noma"). Noma is a leading North American producer of
insulated wire and wire-related products for the automotive, appliance and
electronic industries. Funding for these transactions was provided by existing
cash and borrowings under GCG's revolving credit facility. The acquisitions are
accounted for under the purchase method, and accordingly, the net assets and
results of operations are included in the financial statements from the date of
their respective acquisitions. The allocation of purchase price of Defiance is
based on valuation information available to the Company which is subject to
change as such information is finalized. Goodwill is being amortized on a
straight line basis over a period which ranges from 25 to 35 years. Had the
acquisitions occurred as of January 1, 1998, net sales would have been $223,911
and $207,139 for the three months ended March 31, 1998 and 1999, respectively.
Net income would have been $12,690 and $9,397 for the three months ended March
31, 1998 and 1999, respectively.

</TABLE>

     In connection with the Spinoff, GenTek and GCG arranged for separate credit
facilities, the proceeds of which were used to repay outstanding borrowings of
GCG under its existing credit facilities prior to the Spinoff. On April 30,
GenTek put in place, with a syndicate of banks and other financial institutions,
credit facilities totaling $550,000, consisting of a $300,000 revolving credit
facility maturing in 2005 and term loans of $100,000 and $150,000 maturing in
2005 and 2007, respectively.

NOTE 8 - 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.

NOTE 9 - RELATED PARTY TRANSACTIONS

MANAGEMENT AGREEMENT

     The Company is party to a management agreement with Latona Associates
("Latona") which is controlled by a stockholder of the Company under which the
Company receives corporate supervisory and administrative services and strategic
guidance. Prior to the Spinoff, Latona provided these services to the GenTek
Business pursuant to its agreement with GCG. The Company was charged $1,195 and
$1,368 for the three months ended March 31, 1998 and 1999, respectively.

     In connection with the Spinoff, Latona agreed to provide its services
separately to GenTek and GCG. GenTek will pay Latona, subsequent to the Spinoff,
a quarterly fee of $1,125, to be adjusted after 1999 for increases in U.S. CPI.
In addition, if Latona provides advisory services to GenTek in connection with
any acquisition, business combination or other strategic transaction, GenTek
will pay Latona Associates additional fees comparable with fees received by
investment banking firms for such services. During 1998, the Company paid Latona
$500 in connection with the acquisition of Reheis and during the first quarter
of 1999 paid Latona a fee of $600 in connection with the acquisition of
Defiance. This agreement expires on December 31, 2004.

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 $34.5 million at March 31, 1999 compared
with $61.3 million at year-end 1998 with the decline related to the February
1999 acquisition of Defiance Inc., which was funded with cash and bank
borrowings. During the first three months of 1999, the Company generated cash
flow from continuing operations activities of $4.2 million, had net proceeds
from debt of $27.0 million and cash flow from discontinued operations of $10.4
million, which was used to fund acquisitions of $57.7 million and capital
expenditures of $8.3 million.

     The Company had working capital of $12.4 million at March 31, 1999 as
compared with $17.3 million at December 31, 1998. This decrease in working
capital principally reflects lower cash balances due to the acquisition of
Defiance partially offset by the working capital of Defiance.

     The increases in property, plant and equipment, goodwill and long-term debt
reflect the assets and debt related to the Defiance acquisition.

Results of Operations

     Net revenues for the three month period ended March 31, 1999 increased 27
percent to $127.8 million, from $100.5 million for the comparable period in
1998. This increase is due to higher sales in both the Manufacturing and
Performance Products Segments related to the acquisitions of Defiance in
February 1999 and Reheis in April 1998.

     Gross profit for the three month period ended March 31, 1999 increased 21
percent to $34.8 million from $28.8 million for the comparable prior year
period. Gross profit as a percentage of sales decreased by two percentage points
to 27 percent for the three months ended March 31,1999 versus 29 percent for the
three month period ended March 31, 1998, principally due to lower margins in the
acquired businesses and pricing pressures in certain of the Company's
performance chemical markets.

     Selling, general and administrative expense was $16.6 million for the three
months ended March 31, 1999 as compared to $12.3 million for the first three
months of 1998 principally due to the inclusion of Reheis and Defiance that were
not in the 1998 period.

     Interest expense for the three month period ended March 31, 1999 was $4.3
million, which was $1.6 million higher than the comparable prior year level as a
result of higher outstanding debt balances following 1998 and 1999 acquisitions.

Liquidity and Capital Resources

     In connection with the Spinoff, GenTek and GCG arranged for separate credit
facilities, the proceeds of which were used to repay outstanding borrowings of
GCG under its existing credit facilities prior to the Spinoff. On April 30,
GenTek put in place, with a syndicate of banks and other financial institutions,
credit facilities totaling $550 million, consisting of a $300 million revolving
credit facility maturing in 2005 and term loans of $100 million and $150 million
maturing in 2005 and 2007, respectively. The related agreements contain certain
restrictive covenants related to maximum leverage and minimum interest coverage
to be maintained by the Company.

YEAR 2000 ISSUE

     The Company has implemented a program to assess, mitigate and remediate the
potential impact of the Year 2000 problem. A Year 2000 problem can 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.

     Pursuant to agreements entered into in connection with the Spinoff, GenTek
provides GCG with MIS and MIS-supported functions, including MIS personnel,
hardware and software on a service contract basis. GenTek will provide these
services to GCG through approximately December 2001. During this period, GenTek
will provide to New GCG the services related to the mitigation and remediation
of the potential impact of Year 2000 problems on the Industrial Chemicals
Business.

     The Company completed its assessment of its Year 2000 compliance status in
early 1997 and began work on its remediation program immediately thereafter. The
Company's remediation program has been structured to address its information and
non-information technology hardware, software, facilities and equipment
(collectively, "Systems"). GenTek has spent approximately $1.0 million to
replace or reprogram existing Systems for the Year 2000 compliance program. All
material Systems were Year 2000 compliant by March 31, 1999 and substantially
all Systems will be Year 2000 compliant by December 31, 1999. In the event that
the Company's 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 has implemented a program to determine the Year
2000 compliance status of its material vendors, suppliers, service providers and
customers, including the railroad and trucking companies used to ship its
products or to transport raw materials to its manufacturing facilities. Based on
currently available information, the Company 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. The Company believes there exists a sufficient
number of suppliers of raw materials for the Company so that if any supplier is
unable to deliver raw materials due to Year 2000 problems, alternate sources
will be available and that any supply interruption will not be material to the
Company. There can be no assurances, however, that the Company would be able to
obtain all of its supply requirements from such alternate sources in a timely
manner or on terms comparable with those of its current suppliers. If the
railroads or trucking companies that ship its products or raw materials fail to
be year 2000 compliant, the Company may not be able to arrange alternative and
timely means to ship its goods or raw materials, 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 materials 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 tranporters.

     Before proceeding with the acquisitions of Defiance and Noma and as part of
its acquisition-related due diligence, the Company reviewed Year 2000-related
concerns for Defiance and Noma and received assurances from their respective
managements that their businesses are, or prior to year-end 1999 will be,
materially Year 2000 compliant. As part of its pre-acquisition due diligence,
the Company reviewed, for Defiance, the assessments and reports prepared by its
outside consultants and, for Noma, the periodic internal reports prepared by MIS
personnel for senior management. The Company began its own Year 2000 assessment
for Defiance following the closing of its acquisition and has started its Year
2000 assessment for Noma. In the event that the material systems for Defiance or
Noma are not Year 2000 compliant, the affected company may experience reductions
or interruptions in operations which could have a material adverse effect on the
results of operations or financial condition of the Company.

QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company's cash flows and earnings are subject to fluctuations resulting
from changes in interest rates and changes in foreign currency exchange rates
and the Company selectively uses financial instruments to manage these risks.
The Company's objective in managing its exposure to changes in foreign currency
exchange rates and interest rates is to reduce volatility on earnings and cash
flow associated with such changes. The Company has not entered, and does not
intend to enter, into financial instruments for speculation or trading purposes.

     The Company measures the market risk related to its holding of financial
instruments based on changes in interest rates and foreign currency rates using
a sensitivity analysis. The sensitivity analysis measures the potential loss in
fair values, cash flows and earnings based on a hypothetical 10 percent change
in interest and currency exchange rates. The Company used current market rates
on its debt and derivative portfolio to perform the sensitivity analysis. Such
analysis indicates that a hypothetical 10 percent change in interest rates or
foreign currency exchange rates would not have a material impact on the fair
values, cash flows or earnings of the Company. However, the recent acquisition
of Noma could have a material impact on the Company's exposure in the future to
fluctuations in the C$/US$ exchange rate.

                           PART II. OTHER INFORMATION


ITEM 5. OTHER INFORMATION

     On February 26, 1999, GCG reported that it had entered into an acquisition
agreement with Noma Industries Limited ("Noma"), a corporation incorporated
under the laws of Ontario, Canada. In April 1999, GCG acquired all of the issued
and outstanding Class A and B shares of capital stock at CDN $9.25 per share.
The aggregate purchase price will total approximately CDN $330. This transaction
is described in the Form 8-K filed by GCG with the SEC on February 26, 1999,
which Form 8-K is incorporated herein by reference.

     On March 18, 1999, GCG filed a Form 8-K with the SEC to report the
separation of its manufacturing and performance products segments from its
industrial chemicals segment through the Spinoff. GCG accomplished the Spinoff
by transferring its manufacturing and performance products segments to its
subsidiary, GenTek Inc., and distributing the stock of GenTek Inc. to
shareholders of GCG. As a result of the Spinoff, completed on April 30, 1999,
GCG and GenTek Inc. became separate, independent companies. This transaction
is described in the Form 10 filed with the SEC on April 8, 1999, which is
incorporated herein by reference.
