Note 3:   Contingencies

Asbestos Litigation Against GAFBMC

     In connection with its formation, the Company contractually assumed and
agreed to pay the first $204.4 million of liabilities for asbestos-related
bodily injury claims relating to the inhalation of asbestos fiber ("Asbestos
Claims") (whether for indemnity or defense) of its parent, GAFBMC, relating to
pending cases and previously settled, but not paid, cases as of January 31,
1994, and no other asbestos liabilities of GAFBMC.  As of March 30, 1997, the
Company had paid all of its assumed asbestos-related liabilities.

Note 3.  Contingencies (Continued)


     GAFBMC has advised the Company that, as of March 28, 1998, it is defending
approximately 98,700 lawsuits involving alleged Asbestos Claims, having
resolved approximately 245,000 Asbestos Claims.  During the first quarter of
1998, GAFBMC resolved approximately 10,500 Asbestos Claims and received notice
of approximately 29,900 new Asbestos Claims.

     GAFBMC has stated that it is committed to effecting a comprehensive
resolution of Asbestos Claims, that it is exploring a number of options, both
judicial and legislative, to accomplish such resolution, but there can be no
assurance that this effort will be successful.

     The Company believes that it will not sustain any additional liability in
connection with asbestos-related claims.  While the Company cannot predict
whether any asbestos-related claims will be asserted against it or its assets,
or the outcome of any litigation relating to such claims, it believes that it
has meritorious defenses to such claims.  Moreover, it has been jointly and
severally indemnified by G-I Holdings and GAFBMC with respect to such claims.

     For further information regarding the history of the foregoing litigation
and asbestos-related matters, see "Item 3. Legal Proceedings" and Note 3 to
Consolidated Financial Statements contained in the Company's Form 10-K.


Environmental Litigation

     The Company, together with other companies, is a party to a variety of
proceedings and lawsuits involving environmental matters ("Environmental
Claims"), in which recovery is sought for the cost of cleanup of contaminated
sites, a number of which Environmental Claims are in the early stages or have
been dormant for protracted periods.  At most sites, the Company anticipates
that liability will be apportioned among the companies found to be responsible
for the presence of hazardous substances at the site.  The Company believes
that the ultimate disposition of such matters will not, individually or in the
aggregate, have a material adverse effect on the business, liquidity, results
of operations, cash flows or financial position of the Company.

     For further information regarding environmental matters and other
litigation, reference is made to "Item 3. Legal Proceedings" contained in the
Company's Form 10-K.

Note 3.  Contingencies (Continued)


Tax Claim Against GAF

     On September 15, 1997, GAF received a notice from the Internal Revenue
Service (the "Service") of a deficiency in the amount of $84.4 million (after
taking into account the use of net operating losses and foreign tax credits
otherwise available for use in later years) in connection with the formation in
1990 of Rhone-Poulenc Surfactants and Specialties, L.P. (the "surfactants
partnership"), a partnership in which a subsidiary of GAF, GAF Fiberglass
Corporation ("GFC"), holds an interest.  The claim of the Service for interest
and penalties, after taking into account the effect on the use of net
operating losses and foreign tax credits, could result in GFC incurring
liabilities significantly in excess of the deferred tax liability of $131.4
million that GAF recorded in 1990 in connection with this matter.  GAF has
advised the Company that it believes that GFC will prevail in this matter,
although there can be no assurance in this regard.  The Company believes that
the ultimate disposition of this matter will not have a material adverse effect
on its financial position or results of operations.  GAF, G-I Holdings and
certain subsidiaries of GAF have agreed to jointly and severally indemnify the
Company against any tax liability associated with the surfactants partnership,
which the Company would be severally liable for, together with GAF and several
current and former subsidiaries of GAF, should GFC be unable to satisfy such
liability.

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


Results of Operations - First Quarter 1998 Compared With
                        First Quarter 1997

     The Company recorded first quarter 1998 net income of $2.2 million
compared with $1.8 million in the first quarter of 1997.  The 22.2% increase in
net income reflected higher investment income, partially offset by lower
operating income and higher interest expense.

     The Company's net sales for the first quarter of 1998 were $212.4 million,
a 9.9% increase over last year's sales of $193.3 million.  The sales growth
occurred in both residential and commercial products.  The increase in
residential product sales reflected higher unit volumes, partially offset by
lower average selling prices.  The increase in commercial product sales
reflected both higher unit volumes and higher average selling prices.

     Gross profit margin decreased slightly to 25.6% in the first quarter of
1998 from 25.9% in the first quarter of 1997, resulting primarily from the
lower average residential selling prices, partially offset by lower
manufacturing costs.

     Operating income for the first quarter of 1998 was $6.0 million compared
with $9.3 million in the first quarter of 1997.  The decline in operating
income was attributable to increased selling, general and administrative
expenses, partially offset by the impact of higher product sales.  Selling,
general and administrative expenses increased by 18.3% to $48.4 million
compared with last year's $40.9 million.  In addition to higher expenses
resulting from increased sales volume, the Company incurred increased
distribution costs due to rail carrier service problems in certain regions of
the country requiring utilization of higher-cost transportation alternatives,
together with higher expenses relating to expanded marketing efforts.

     Interest expense increased to $12.7 million in the first quarter of 1998
from $9.8 million last year due to higher debt levels, mainly reflecting the
issuance in October 1997 of $100 million in aggregate principal amount at
maturity of 8% Senior Notes due 2007.  Other income, net, was $10.3 million for
the quarter compared with $3.4 million last year, reflecting higher investment
income.


Liquidity and Financial Condition

     Net cash inflow during the first quarter of 1998 was $21.6 million before
financing activities, and included the use of $2.6 million of cash for
operations, the reinvestment of $11.7 million for capital programs, and the
generation of $35.9 million from net sales of available-for-sale and held-to-
maturity securities.

                                       
                                       
                                       
                                       
                                       9
<PAGE>
     Cash invested in additional working capital totaled $36.8 million during
the first quarter of 1998, primarily reflecting a seasonal increase in
inventories of $31.8 million and a $28.9 million increase in the receivable
from the trust which purchases the Company's trade accounts receivable,
partially offset by a $25.4 million increase in accounts payable and accrued
liabilities.  Accrued liabilities increased by $14.7 million to $41.0 million
as a result of additional accrued interest payable and seasonal increases in
accrued distribution costs and other plant operating accruals.  Cash from
operating activities also reflected a $10.3 million cash inflow from related
party transactions and a $4.0 million cash inflow from net sales of trading
securities.

     Net cash used in financing activities totaled $22.3 million during the
first quarter of 1998, mainly reflecting a $14.0 million decrease in borrowings
under the Company's bank revolving credit facility and a $10.5 million decrease
in short-term borrowings, partially offset by a $6.2 million cash inflow from
the repayment of a loan to a related party.

     As a result of the foregoing factors, cash and cash equivalents decreased
by $0.7 million during the first quarter to $12.2 million (excluding $194.0
million of trading and available-for-sale securities and other short-term
investments).

     The Company has significantly upgraded its information systems
capabilities and is in the process of finalizing the roll-out of an interactive
network connecting all of its locations.  In conjunction with this initiative,
the Company is addressing its "Year 2000" compliance issues and does not
believe that the costs associated with, or the impact of, these issues will
have a material adverse effect on the operations, liquidity or capital
resources of the Company.  At this time, the Company has no information
concerning the impact of Year 2000 issues on its suppliers and customers.

     See Note 3 to Consolidated Financial Statements for information regarding
contingencies.
