Note 2.   Contingencies

Asbestos Litigation Against G-I Holdings

     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") of its parent, G-I Holdings. As of March 30, 1997, the Company had paid
all of its assumed asbestos-related liabilities. In January 2001, G-I Holdings
filed a voluntary petition for reorganization under Chapter 11 of the U.S.
Bankruptcy Code due to its Asbestos Claims. This proceeding remains pending.

     Claimants in the G-I Holdings bankruptcy, including judgment creditors,
might seek to satisfy their claims by asking the bankruptcy court to require the
sale of G-I Holdings' assets, including its holdings of BHC's common stock and
its indirect holdings of the Company's common stock. That action could result in
a change of control of the Company. In addition, those claimants may seek to
file Asbestos Claims against the Company (with approximately 1,900 alleged
Asbestos Claims pending against the Company as of September 29, 2002). The
Company believes that it will not sustain any liability in connection with

     these or any other asbestos-related claims. Furthermore, on February 2,
2001, the United States Bankruptcy Court for the District of New Jersey issued a
temporary restraining order enjoining any existing or future claimant from
bringing Asbestos Claims against the Company. On June 22, 2001, following a
hearing, the Bankruptcy Court converted the temporary restraining order into a
preliminary injunction, which is expected to remain in effect pending
confirmation of a Chapter 11 plan of reorganization for the G-I Holdings estate.
On February 7, 2001, G-I Holdings and the Company filed a defendant class action
in the United States Bankruptcy Court for the District of New Jersey seeking a
declaratory judgment that the Company has no successor liability for Asbestos
Claims against G-I Holdings and that it is not the alter ego of G-I Holdings. No
trial date has been set by the court. As a result, it is not possible to predict
the outcome of this litigation. On May 3, 2002, G-I Holdings and the Company
filed a summary judgment motion seeking entry of judgment against the Named
Defendants in the action declaring that BMCA is not liable to them under any
theory of successor liability or alter ego. On July 1, 2002, the statutory
creditors' committee (the "Committee") appointed by the G-I Holdings bankruptcy
court filed a motion with the U.S. District Court to withdraw the reference of
the declaratory judgment motion to the bankruptcy court. There has been no court
ruling on either the motion for summary judgment or the motion to withdraw the
reference. On October 18, 2002, the Bankruptcy Court granted the motions filed
by G-I Holdings and the Company to file an amended complaint to add as a
defendant the legal representative of future demands in the G-I Holdings
bankruptcy and to remove the class action allegations, on which motions the
court has not ruled. While the Company cannot predict whether any additional
Asbestos Claims will be asserted against it, or the outcome of any litigation
relating to those claims, the Company believes that it has meritorious defenses
to any claim that it has asbestos-related liability, although there can be no
assurances in this regard.

     On February 8, 2001, the Committee established in G-I Holdings' bankruptcy
case filed a complaint in the United States Bankruptcy Court for the District of
New Jersey against G-I Holdings and the Company. The complaint requests
substantive consolidation of the Company with G-I Holdings or an order directing
G-I Holdings to cause the Company to file for bankruptcy protection. The Company
and G-I Holdings intend to vigorously defend the lawsuit. The Company believes
that no basis exists for the court to grant the relief requested. The plaintiffs
also filed for interim relief absent the granting of their requested relief
described above. On March 21, 2001, the Bankruptcy Court refused to grant the
requested interim relief.

     For a further discussion with respect to the history of the foregoing
litigation and asbestos-related matters, see Item 3,"Legal Proceedings," and
Notes 3, 11 and 16 to Consolidated Financial Statements contained in the
Company's Form 10-K.

Note 2.   Contingencies (Continued)

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 or remedial obligations are imposed, 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 liquidity, financial position or results of operations 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.

Tax Claim Against G-I Holdings

     The Company and certain of its subsidiaries were members of the
consolidated group (the "G-I Holdings Group") for Federal income tax purposes
that included G-I Holdings in certain prior years and, accordingly, would be
severally liable for any tax liability of the G-I Holdings Group in respect of
those prior years.

     On September 15, 1997, G-I Holdings received a notice from the Internal
Revenue Service (the "IRS") 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., a
partnership in which G-I Holdings held an interest. G-I Holdings has advised the
Company that it believes that it will prevail in this tax 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
business, financial position or results of operations. On September 21, 2001,
the Internal Revenue Service filed a proof of claim with respect to such
deficiency against G-I Holdings in the G-I Holdings bankruptcy. On May 7, 2002,
G-I Holdings filed an objection to that proof of claim. On July 13, 2002, the
IRS filed a motion with the U.S. District Court for a withdrawal of the
reference of G-I Holdings' objection to the proof of claim to the bankruptcy
court. If the IRS's proof of claim is sustained, the Company and/or certain of
the Company's subsidiaries together with G-I Holdings and several current and
former subsidiaries of G-I Holdings would be severally liable for a portion of
those taxes and interest. If the IRS were to prevail for the years in which the
Company and/or certain of its subsidiaries were part of the G-I Holdings Group,
the Company would be severally liable for approximately $40.0 million in taxes
plus interest, although this calculation is subject to uncertainty depending
upon various factors including G-I Holdings' ability to satisfy its tax
liabilities and the application of tax credits and deductions.

Note 3.    New Accounting Standards

     On June 30, 2001, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 142, "Goodwill and Other
Intangible Assets". With the adoption of SFAS No. 142, effective January 1,
2002, goodwill is no longer subject to amortization over its estimated useful
life. However, goodwill will be subject to at least an annual assessment for
impairment and more frequently if circumstances indicate a possible impairment.
The Company performed an initial fair-value-based goodwill impairment test in
the second quarter of 2002. This test resulted in an evaluation that there was
no impairment as of January 1, 2002.

     Net income exclusive of amortization expense for goodwill no longer being
amortized is as follows:

Note 4.  Subsequent Event

     On October 4, 2002, the Company exercised an Early Buyout Option amounting
to $9.4 million in connection with its sale-leaseback of certain equipment
located at its Baltimore, Maryland roofing facility which had been accounted for
as a capital lease.

Note 5.  Guarantor Financial Information

     All of the Company's subsidiaries, other than BMCA Receivables Corporation,
are guarantors under the Company's $100 million secured bank credit facility,
the amended and restated $110 million secured bank credit facility, the 10 1/2%
Senior Notes due 2003, the 7 3/4% Senior Notes due 2005, the 8 5/8% Senior Notes
due 2006, the 8% Senior Notes due 2007 (the "2007 Notes"), and the 8% Senior

fee stated as a percentage of net sales. The license agreements are for a period
of one year and are subject to automatic renewal unless either party terminates
with 60 days written notice. Also, effective January 1, 1999, BMMC sells all
finished goods to the Company at a manufacturing profit. Such transactions have
been eliminated in consolidation.

information for the Company, the guarantor subsidiaries and the non-guarantor
subsidiary is not included herein because management has determined that such
information is not material to investors.

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

Results of Operations -  Third Quarter 2002 Compared With
                         Third Quarter 2001

     We recorded net income in the third quarter of 2002 of $15.7 million
compared with net income of $16.9 million in the third quarter of 2001. The
decline in net earnings in the third quarter of 2002 was primarily due to lower
operating income partially offset by lower interest expense.

     Net sales for the third quarter of 2002 were $357.1 million, a decrease
from last year's net sales of $376.3 million, with the decline primarily due to
lower net sales of residential roofing products. The decrease in net sales of
residential roofing products in the third quarter of 2002 reflected lower unit
volumes as the harsh winter in 2001 caused a delay in demand in colder climates
resulting in unusually strong sales in the third quarter of 2001, partially
offset by slightly higher average selling prices. Net sales of commercial
roofing products for the third quarter of 2002 were relatively flat compared to
2001.

     Operating income in the third quarter of 2002 was $40.1 million compared
with $43.6 million in the third quarter of 2001. The decrease in operating
income was primarily attributable to lower net sales of residential roofing
products, as discussed above. The third quarter of 2002 also reflected lower
manufacturing costs and lower selling, general and administrative expenses that
essentially offset the impact of higher asphalt costs due to higher oil prices.
As a result of the initial adoption of Statement of Financial Accounting
Standards ("SFAS") No. 142, "Goodwill and Other Intangible Assets", goodwill
amortization, which amounted to $0.5 million in the third quarter of 2001, no
longer is being amortized in 2002.

     Interest expense for the third quarter of 2002 decreased to $13.8 million
from $15.1 million for the same period in 2001, primarily due to lower average
borrowings and a lower average interest rate. Other expense, net was $1.8
million for the third quarter of 2002 compared with $1.8 million for the same
period in 2001.

Results of Operations - Nine Months 2002 Compared With
                        Nine Months 2001

     For the first nine months of 2002, we recorded net income of $36.1 million
compared with net income of $21.7 million in the first nine months of 2001,
representing an increase of 66.4%. The increased net earnings in 2002 was
primarily the result of higher operating income on higher net sales and lower
manufacturing costs together with lower interest expense.

     Net sales for the first nine months of 2002 were $1,045.8 million, compared
with $996.2 million in the same period of 2001, representing an increase of
5.0%. Net sales gains of residential roofing products were partially offset by
lower net sales of commercial roofing products. The increase in net sales of
residential roofing products reflected higher average selling prices and higher
unit volumes, while the decline in net sales of commercial roofing products was
attributable to lower average selling prices and slightly lower unit volumes.

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

     Operating income for the first nine months of 2002 was $104.1 million
compared with $85.4 million in 2001, representing an increase of 21.9%. The
increase in operating income was primarily attributable to higher net sales of
residential roofing products together with lower manufacturing costs, partially
offset by higher selling, general and administrative expenses and lower net
sales of commercial roofing products. As a result of the adoption of SFAS No.
142, goodwill amortization, which amounted to $1.5 million in the first nine
months of 2001, no longer is being amortized in 2002.

     Interest expense for the first nine months of 2002 decreased to $41.5
million from $45.7 million for the same period in 2001, primarily due to lower
average borrowings and a lower average interest rate. Other expense, net was
$6.1 million for the first nine months of 2002 compared with $5.3 million for
the same period in 2001.


Liquidity and Financial Condition

     Net cash inflow during the first nine months of 2002 was $16.8 million,
before financing activities, and included $32.6 million of cash generated from
operations and the reinvestment of $15.8 million for capital programs.

     Cash invested in additional working capital totaled $73.2 million during
the first nine months of 2002, primarily reflecting seasonal increases in
accounts receivable of $71.3 million and $25.7 million in inventories, partially
offset by a $23.5 million increase in accounts payable and accrued liabilities.
Cash from operating activities also included $15.3 million of net proceeds from
the sale of accounts receivable to a third party in connection with our Accounts
Receivable Securitization Agreement and a $4.2 million net increase in the net
payable to related parties/parent corporations.

     Net cash used in financing activities totaled $6.6 million during the first
nine months of 2002, reflecting $4.3 million in repayments of long-term

forward-looking statements. All statements other than statements of historical
fact are, or may be deemed to be, forward-looking statements within the meaning
of section 27A of the Securities Act of 1933 and section 21E of the Securities
Exchange Act of 1934. These forward-looking statements are only predictions and
generally can be identified by use of statements that include phrases such as
"believe," "expect," "anticipate," "intend," "plan," "foresee" or other words or
phrases. Similarly, statements that describe the Company's objectives, plans or
goals also are forward-looking statements. The Company's operations are subject
to certain risks and uncertainties that could cause actual results to differ
materially from those contemplated by the relevant forward-looking statement.
The forward-looking statements included herein are made only as of the date of
this Quarterly Report on Form 10-Q and the Company undertakes no obligation to
publicly update forward-looking statements to reflect subsequent events or
circumstances. No assurances can be given that projected results or events will
be achieved.

     The Company's Chief Executive Officer and Chief Financial Officer are
responsible for the design, maintenance and effectiveness of disclosure controls
and procedures (as defined in the Rules 13a-14(c) and 15d-14(c) of the
Securities Exchange Act of 1934).

     The effectiveness of the disclosure controls and procedures have been
evaluated by the Chief Executive Officer and Chief Financial Officer within 90
days of the filing date of this report. Based on this evaluation, the Chief
Executive Officer and Chief Financial Officer have concluded that the disclosure
controls and procedures are adequate and effective.

     There have been no significant changes in internal controls or in other
factors that could significantly affect these internal controls subsequent to
the date of the evaluation in connection with the preparation of this quarterly
report on Form 10-Q.
