ITEM 1. BUSINESS

GENERAL

Building Materials Corporation of America ("BMCA") is a leading national
manufacturer of a broad line of asphalt roofing products and accessories for the
residential and commercial roofing markets. We also manufacture specialty
building products and accessories for the professional and do-it-yourself
remodeling and residential construction industries. BMCA, incorporated under the
laws of Delaware in 1994, is, as of March 24, 2000, a 99.4%-owned subsidiary of
BMCA Holdings Corporation, which is a 97%-owned subsidiary of GAF Building
Materials Corporation. BMCA acquired the operating assets and certain
liabilities of GAF Building Materials Corporation in 1994. GAF Building
Materials Corporation is a wholly-owned subsidiary of GAF Fiberglass
Corporation, which is a wholly-owned subsidiary of G Industries Corp.
G Industries is a wholly-owned subsidiary of G-I Holdings Inc., which is a
wholly-owned subsidiary of GAF Corporation. Samuel J. Heyman, Chairman of the
Board of Directors, President and Chief Executive Officer of GAF Corporation,
G-I Holdings and GAF Fiberglass, Chairman of the Board of Directors and Chief
Executive Officer of BMCA and President and Chief Executive Officer of G
Industries, GAF Building Materials Corporation and BMCA Holdings, beneficially
owns (as defined in Rule 13d-3 of the Exchange Act) approximately 99% of GAF
Corporation. BMCA does business under the name "GAF Materials Corporation."

Effective January 1, 1999, BMCA transferred all of its investment assets
and intellectual property assets to Building Materials Investment Corporation, a
newly-formed, wholly-owned subsidiary of BMCA. In connection with this transfer,
Building Materials Investment Corporation agreed to guarantee all of BMCA's
obligations under its credit agreement and all of its senior notes. BMCA also
transferred all of its manufacturing assets, other than those located in Texas,
to Building Materials Manufacturing Corporation, another newly-formed,
wholly-owned subsidiary of BMCA. In connection with this transfer, Building
Materials Manufacturing Corporation agreed to become a co-obligor on BMCA's 8%
Senior Notes due 2007 and to guarantee BMCA's obligations under its credit
agreement and all of its other senior notes. Building Materials Manufacturing
Corporation and Building Materials Investment Corporation were incorporated in
Delaware in 1998.

On January 1, 1997, GAF Corporation, our indirect parent, completed a
series of transactions involving its subsidiaries, in which among other things,
(1) we transferred our glass fiber manufacturing facility located in Nashville,
Tennessee and certain related assets and liabilities to GAF Fiberglass
Corporation, and (2) U.S. Intec, Inc., an indirect subsidiary of GAF
Corporation, became one of our subsidiaries. In connection with these
transactions, GAF Fiberglass entered into a long-term supply agreement with us
pursuant to which GAF Fiberglass agreed to supply us with glass fiber. Effective
August 18, 1999, GAF Fiberglass, in a series of transactions, contributed to us
certain assets, including the Nashville glass fiber manufacturing facility, and
certain related liabilities. See Item 13, "Certain Relationships and Related
Transactions."

Our executive offices and the executive offices of Building Materials
Manufacturing Corporation are located at 1361 Alps Road, Wayne, New Jersey 07470
and the telephone number is (973) 628-3000. The executive offices of Building
Materials Investment Corporation are located at 300 Delaware Avenue, Suite 303,
Wilmington, Delaware 19801 and the telephone number is (302) 427-5960.

RESIDENTIAL ROOFING

We are a leading manufacturer of a complete line of premium residential
roofing products. Residential roofing product sales represented approximately
65% of our net sales in 1999. We have improved our sales mix of residential
roofing products in recent years by increasing our emphasis on laminated
shingles and accessory products which generally are sold at higher prices with
more attractive profit margins than our standard strip shingle products. We
believe that we are the largest manufacturer of laminated residential roofing
shingles and the second largest manufacturer of strip shingles in the United
States. (Statements contained in this report as to our competitive position are
based on industry information which we believe is reliable.)

1

Our two principal lines of residential roofing shingles are the
Timberline(R) series and the Sovereign(R) series. We also produce certain
specialty shingles principally for regional markets.

The Timberline(R) Series. The Timberline(R) series offers a premium
laminated product line that adds dramatic shadow lines and substantially
improves the appearance of a roof. The series includes:

o the Timberline(R)25 shingle, a mid-weight laminated shingle which serves
as an economic trade-up for consumers, with a 25-year limited warranty;

o the Timberline(R) shingle, with a 30-year limited warranty, offering a
natural random wood shake appearance with superior fire resistance and
durability; and

o the Timberline Ultra(R) shingle, with a 40-year limited warranty, a super
heavyweight laminated shingle with the same design features as the
Timberline(R) 25 shingle, together with added durability.

The Sovereign(R)Series. The Sovereign(R)series includes:

o the standard 3-tab Sentinel(R)shingle with a 20-year limited warranty;

o the Royal Sovereign(R) shingle, a heavier 3-tab shingle with a 25-year
limited warranty, designed to capitalize on the "middle market" for
quality shingles; and

o the Marquis(R) Weathermax(TM) shingle, a superior performing heavyweight
3-tab shingle with a 30-year limited warranty.

Specialty Shingles. Our specialty asphalt shingles include:

o Slateline(R) and Slateline(R) Color Contrast(TM) shingles, offering the
appearance of slate, labor savings in installation because of their
larger size and a 40-year limited warranty;

o the Grand Sequoia(R)shingle, a premier architectural shingle with a
40-year limited warranty; and

o the Country Mansion(TM)shingle, a distinctive high-end architectural
shingle with a limited lifetime warranty.

Weather Stopper(TM) Roofing System. In addition to shingles, we supply all
the components necessary to install a complete roofing system. Our Weather
Stopper(TM) Roofing System begins with Weather Watch(R) and Stormguard(TM)
waterproof underlayments for eaves, valleys and flashings to prevent water
seepage between the roof deck and the shingles caused by ice build-ups and
wind-driven rains. Our Weather Stopper(TM) Roofing System also includes
Shingle-Mate(R) glass reinforced underlayment, Timbertex(R), TimberRidge(TM) and
Timberline(R) Hip and Ridge shingles, which are significantly thicker and larger
than standard hip and ridge shingles and provide dramatic accents to the slopes
and planes of a roof, and the Cobra(R) Ridge Vent, which provides attic
ventilation.

COMMERCIAL ROOFING

We manufacture a full line of modified bitumen and asphalt built-up roofing
products, liquid applied membrane systems and roofing accessories for use in the
application of commercial roofing systems. We also market thermoplastic and
elastomeric single-ply products. Commercial roofing represented approximately
27% of our net sales in 1999. We believe that we are the second largest
manufacturer of asphalt built-up roofing products and the largest manufacturer
of modified bitumen products in the United States.

We manufacture glass membranes under the trademarks GAFGLAS(R) and
Permaglas(R), which are made from asphalt impregnated glass fiber mat for use as
a component in asphalt built-up roofing systems. Most of our GAFGLAS(R) and
Permaglas(R) products are assembled on the roof by applying successive layers of
roofing membrane with asphalt and topped, in some applications, with gravel.
Thermal insulation may be applied beneath the membrane. We also manufacture base
sheets, flashings and other roofing accessories for use in these systems, the
TOPCOAT(R) roofing system, a liquid-applied membrane system designed to protect
and waterproof existing metal roofing, and roof maintenance products. In
addition, we market perlite roofing insulation products, which consist of low
thermal insulation that is installed as part of a commercial roofing application
below the roofing membrane, isocyanurate foam as roofing insulation, packaged
asphalt and accessories such as vent stacks, roof insulation fasteners, cements
and coating.

2

We sell modified bitumen products under the Ruberoid(R) trademark, and U.S.
Intec sells these products under the Brai(R) trademark. Modified bitumen
products are used primarily in re-roofing applications or in combination with
glass membranes in GAF CompositeRoof(TM) systems. These products consist of a
roofing membrane utilizing polymer-modified asphalt, which strengthens and
increases flexibility and is reinforced with a polyester non-woven mat or a
glass mat. Modified bitumen systems provide high strength characteristics, such
as weatherability, water resistance and labor cost savings due to ease of
application.

SPECIALTY BUILDING PRODUCTS AND ACCESSORIES

We manufacture and market a variety of specialty building products and
accessories for the professional and do-it-yourself remodeling and residential
construction industries. Specialty building products and accessories represented
approximately 8% of our net sales in 1999. These products primarily consist of
residential attic ventilation systems, metal and fiberglass air distribution
products for the HVAC industry and ornamental iron security products, including
doors, windows and fencing.

MARKETING AND SALES

We have one of the industry's largest sales forces. A staff of technical
professionals who work directly with architects, consultants, contractors and
building owners provide support to the sales force. We market our roofing and
specialty building products and accessories through our own sales force of
approximately 200 experienced, full-time employees and independent sales
representatives operating from six regional sales offices located across the
United States. A major portion of our roofing product sales are to wholesale
distributors who resell our products to roofing contractors and retailers. We
believe that our nationwide coverage has contributed to certain of our roofing
products being among the most recognized and requested brands in the industry.

Our Customer Advantage(TM) Program offers marketing and support services to
a nationwide network of MasterElite(TM) residential roofing contractors and
Authorized Installers. We view the Master Elite(TM) contractors and Authorized
Installers as an effective extension of our sales force which takes our products
directly to the homeowner. We also have established programs with approved
MasterSelect(TM), Platinum(TM) and Pride (TM) contractors to promote premium
warranty systems and service programs for our commercial roofing products.

No single customer accounted for 10% or more of our net sales in 1999,
except for The Home Depot, Inc. and American Builders & Contractors Supply
Company, Inc., which accounted for approximately 11% and 10%, respectively, of
our 1999 net sales.

RAW MATERIALS

The major raw materials required for the manufacture of our roofing
products are asphalt, mineral stabilizer, glass fiber, glass fiber mat,
polyester mat and granules. Asphalt and mineral stabilizer are available from a
large number of suppliers. We currently have contracts with several of these
suppliers and others are available as substitutes. Prices of most raw materials
have been relatively stable, rising moderately with general industrial prices,
while the price of asphalt tends to move in step with the price of crude oil.

The major raw materials required for the manufacture of our specialty
building products and accessories are steel tubes, sheet metal products,
aluminum motors and cartons. These raw materials, other than motors, are
commodity-type products, the pricing for which is driven by supply and demand.
Prices of other raw materials used in the manufacture of specialty building
products and accessories are more closely tied to movements in inflation rates.
In 1999, substantially all of the motors used in our ventilation products were
purchased from an overseas supplier. All of these raw materials, including
motors, are available from a large number of suppliers.

Five of our roofing plants have easy access to deep water ports thereby
permitting delivery of asphalt by ship, the most economical means of transport.
Our Nashville, Tennessee plant manufactures a significant portion of our glass
fiber requirements for use in our Chester, South Carolina plant which
manufactures glass fiber mat substrate. We purchase all of our requirements for
colored roofing granules from an affiliate, International Specialty Products
Inc., under a requirements contract, except for the requirements of our
California and Oregon roofing plants and a portion of the requirements of our
Indiana roofing plant, which

3

are supplied by a third party. This contract is subject to annual renewal unless
terminated by either party to the agreement.

SEASONAL VARIATIONS AND WORKING CAPITAL

Sales of roofing and specialty building products and accessories in the
northern regions of the United States generally decline during the winter months
due to adverse weather conditions. Generally, our inventory practice includes
increasing inventory levels in the first and the second quarter in order to meet
peak season demand (June through November).

WARRANTY CLAIMS

We provide certain limited warranties covering most of our residential
roofing products for periods generally ranging from 20 to 40 years. Although
terms of warranties vary, we believe that our warranties generally are
consistent with those offered by our competitors. We also offer limited
warranties and guarantees of varying duration on our commercial roofing products
and limited warranties covering most of our specialty building products and
accessories for periods generally ranging from 5 to 10 years. From time to time,
we review the reserves established for estimated probable future warranty
claims.

COMPETITION

The roofing products industry is highly competitive and includes a number
of national competitors. These competitors in the residential roofing and
accessories markets are Owens-Corning, Tamko, Elcor and Celotex, and in the
commercial roofing market are Johns Manville, Firestone and Carlisle. In
addition, there are numerous regional competitors.

Competition is based largely upon products and service quality,
distribution capability, price and credit terms. We believe that we are well
positioned in the marketplace as a result of our broad product lines in both the
residential and commercial markets, consistently high product quality, strong
sales force and national distribution capabilities. As a result of the growth in
demand for premium laminated shingles, a number of roofing manufacturers,
including our company, have increased their laminated shingle production
capacity in recent years. We have experienced increased competition in this area
due to these factors.

Our specialty roofing products and accessories business is highly
competitive with numerous competitors due to the breadth of the product lines we
market. Major competitors include Certainteed, Solar Group, ATCO Rubber Products
and Standex Air Distribution Products.

RESEARCH AND DEVELOPMENT

We primarily focus our research and development activities on the
development of new products, process improvements and the testing of alternative
raw materials and supplies. Our research and development activities, dedicated
to residential, commercial and fiberglass products, are located at technical
centers at Wayne, New Jersey and Nashville, Tennessee. Our research and
development expenditures were approximately $5.4, $6.0 and $6.5 million in 1997,
1998 and 1999, respectively.

PATENTS AND TRADEMARKS

We own or license approximately 100 domestic and 100 foreign patents or
patent applications. In addition, we own or license approximately 250 domestic
and 80 foreign trademark registrations or applications. While we believe the
patent protection covering certain of our products to be material to those
products, we do not believe that any single patent, patent application or
trademark is material to our business or operations. We believe that the
duration of the existing patents and patent licenses is consistent with our
business needs.

ENVIRONMENTAL COMPLIANCE

Since 1970, federal, state and local authorities have adopted and amended a
wide variety of federal, state and local environmental laws and regulations
relating to environmental matters. These laws and regulations affect us because
of the nature of our operations and that of our predecessor and certain of the
substances

4

that are, or have been used, produced or discharged at our or its plants or at
other locations. We made capital expenditures of approximately $1.4 million in
the aggregate in 1999 relating to environmental compliance in connection with
the two new manufacturing facilities we are building in Shafter, California and
Michigan City, Indiana. In addition, we made capital expenditures of
approximately $1.3 million in the aggregate in 1999 relating to environmental
compliance in all other locations. In 1998 and 1997, we made capital
expenditures of less than $0.6 million in each year relating to environmental
compliance. These expenditures are included in additions to property, plant and
equipment. We anticipate that aggregate capital expenditures relating to
environmental compliance in 2000 and 2001 will be approximately $2.6 and $1.2
million, respectively.

The environmental laws and regulations deal with air and water emissions or
discharges into the environment, as well as the generation, storage, treatment,
transportation and disposal of solid and hazardous waste, and the remediation of
any releases of hazardous substances and materials to the environment. We
believe that our manufacturing facilities comply in all material respects with
applicable laws and regulations. Although we cannot predict whether more
burdensome requirements will be adopted in the future, we believe that any
potential liability for compliance with the laws and regulations will not
materially affect our business, liquidity or financial position.

See Item 3, "Legal Proceedings--Environmental Litigation."

EMPLOYEES

At December 31, 1999, we employed approximately 3,500 people worldwide,
approximately 1,000 of which were subject to 14 union contracts. The contracts
are effective for three- to four-year periods. During 1999, two labor contracts
expired and were renegotiated. We believe that our relations with our employees
and their unions are satisfactory.

ITEM 2. PROPERTIES

Our corporate headquarters and principal research and development
laboratories are located at a 100-acre campus-like office and research park
owned by a subsidiary of International Specialty Products Inc., at 1361 Alps
Road, Wayne, New Jersey 07470. We occupy our headquarters pursuant to our
management agreement with ISP. See Item 13, "Certain Relationships and Related
Transactions."

We own or lease the principal real properties described below. Unless
otherwise indicated, the properties are owned in fee. In addition to the
principal facilities listed below, we maintain sales offices and warehouses,
substantially all of which are in leased premises under relatively short-term
leases.

provide sufficient capacity to meet production requirements. Each plant has
adequate transportation facilities for both raw materials and finished products.
In 1999, we made capital expenditures of $45.3 million relating to plant,
property and equipment.

ITEM 3. LEGAL PROCEEDINGS

Bodily Injury Claims. In connection with its formation, BMCA 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 of its parent, GAF Building Materials Corporation. As of March 30, 1997,
BMCA had paid all of its assumed asbestos-related liabilities. G-I Holdings and
GAF Building Materials Corporation have jointly and severally agreed to
indemnify BMCA against any other existing or future claims related to asbestos-
related liabilities if asserted against BMCA. We frequently refer to
asbestos-related bodily injury claims relating to the inhalation of asbestos
fiber in this report as "Asbestos Claims."

GAF Corporation has advised that, as of December 31, 1999, it was defending
approximately 115,000 pending alleged Asbestos Claims, having received notice of
approximately 43,100 new Asbestos Claims during 1999. GAF has advised that the
Center for Claims Resolution ("CCR"), a non-profit organization set up to
administer and handle asbestos-related personal injury claims against the
participating companies and in

6


which GAF Corporation was a member, terminated GAF's membership, effective
January 17, 2000. GAF has advised the CCR that such termination was unauthorized
and that it intends to take appropriate measures to protect its rights to pursue
claims against the CCR and its member companies arising out of this improper
termination and for other improper actions. Currently, the disputes between GAF
and the CCR are the subject of pending Alternative Dispute Proceedings.

GAF Corporation has confirmed that it has experienced a significant
increase in the rate of new Asbestos Claims, principally involving claimants
without any asbestos-related impairment, and amounts demanded to settle these
claims. GAF anticipates that these trends could well continue for the
foreseeable future, and that the percentage of Asbestos Claims filed by
individuals with no physical impairment will remain high. GAF has advised that
it expects an increasingly adverse litigation environment in particular
jurisdictions. GAF believes that these trends and the CCR's termination of GAF's
membership resulted from, or were induced by, in no small part, retaliatory
actions taken by asbestos lawyers against GAF in connection with GAF's active
support of proposed legislation currently pending in Congress to address the
national asbestos litigation crisis.

GAF Corporation has stated that it is committed to effecting a
comprehensive resolution of Asbestos Claims, and that it is exploring options to
accomplish this resolution, including the support of the proposed Congressional
legislation, but there can be no assurance that these efforts will be
successful.

We believe that we will not sustain any additional liability in connection
with asbestos-related claims. While we cannot predict whether any
asbestos-related claims will be asserted against us or our assets or the outcome
of any litigation relating to those claims, we believe that we have meritorious
defenses to any claim that could be so asserted. In addition, G-I Holdings and
GAF Building Materials Corporation have jointly and severally indemnified us
with respect to asbestos-related claims, and G-I Holdings has advised us that it
believes it has and will have sufficient resources to enable it to satisfy any
indemnification obligations. However, GAF has advised us that depending upon
whether the trends described above continue, whether other retaliatory actions
are taken, the ultimate resolution of the disputes between GAF and the CCR, and
whether the proposed legislation currently pending in Congress is enacted into
law, its financial condition could be materially adversely affected by one or
more of these factors. Should GAF Corporation or GAF Building Materials
Corporation be unable to satisfy judgments against it in asbestos-related
lawsuits, its judgment creditors might seek to enforce their judgments against
the assets of GAF Corporation, including its holdings of G-I Holdings common
stock, or GAF Building Materials Corporation, including its holdings of our
common stock. This enforcement could result in a change of control with respect
to our company. See Notes 10 and 15 to Consolidated Financial Statements.

Asbestos-in-Building Claims. GAF Corporation has also been named as a
co-defendant in asbestos-in-buildings cases for economic and property damage or
other injuries based upon an alleged present or future need to remove asbestos
containing materials from public and private buildings. We refer to the
asbestos-in-building claims in this report as the "Building Claims." Since these
actions were first initiated approximately 18 years ago, GAF Corporation has not
only successfully disposed of approximately 145 of these cases, but is a
co-defendant in only three remaining lawsuits, one of which has been dormant. No
new Building Claims were filed in 1999. BMCA has not assumed any liabilities
with respect to Building Claims, and G-I Holdings and GAF Building Materials
Corporation have jointly and severally agreed to indemnify BMCA against those
liabilities in the event any claims are asserted against it.

Insurance Matters. GAF Corporation and G-I Holdings had available, as of
December 31, 1999, to pay asbestos-related bodily injury claims aggregate
insurance coverage of approximately $84.0 million before discounting certain
coverage, which amount is reduced as asbestos-related liabilities are satisfied.

In January 1993, GAF Corporation filed an action in the United States
District Court in Philadelphia against certain product liability insurers whose
policies will or may be called upon to respond to asbestos-related bodily injury
claims. This action sought a declaratory judgment against various third-party
defendant product liability insurers to the effect that those insurers are
obligated to provide coverage for Asbestos Claims. In March 2000, GAF
Corporation reached a settlement with the final remaining insurer who was a
defendant in GAF Corporation's amended complaint and anticipates that it will
dismiss this action.

7


In October 1983, GAF Corporation filed a lawsuit in Los Angeles, California
Superior Court against its past insurance carriers to obtain a judicial
determination that those carriers were obligated to defend and indemnify it for
Building Claims. GAF Corporation is seeking declaratory relief as well as
compensatory damages. This action is presently in the pre-trial pleading stage.
The parties have agreed to hold this action in abeyance until such time as they
are better able to evaluate developments as they may occur in the Building
Claims. Because this litigation is in the early stages and evidence and
interpretations of important legal questions are presently unavailable, it is
not possible to predict the future of this litigation.

In all the Building Claims, GAF Corporation's defense costs have been paid
by one of its primary carriers. While GAF Corporation expects that this primary
carrier will continue to defend and indemnify GAF Corporation, this primary
carrier has reserved its rights to later refuse to defend and indemnify GAF
Corporation and to seek reimbursement for some or all of the fees paid to defend
and resolve the Building Claims. GAF Corporation believes that it will be able
to resolve those cases for amounts within the total indemnity obligations
available from this primary carrier.

ENVIRONMENTAL LITIGATION

We, together with other companies, are a party to a variety of proceedings
and lawsuits involving environmental matters under the Comprehensive
Environmental Response Compensation and Liability Act and similar state laws, in
which recovery is sought for the cost of cleanup of contaminated sites, a number
of which are in the early stages or have been dormant for protracted periods. We
refer to these proceedings and lawsuits below as "Environmental Claims."

In connection with its formation, BMCA contractually assumed all
environmental liabilities of GAF Building Materials Corporation relating to
existing plant sites and the business of BMCA as then conducted. The estimates
referred to below reflect those environmental liabilities assumed by BMCA and
other environmental liabilities of our company. The environmental liabilities of
GAF Building Materials Corporation which were not assumed by BMCA, for which G-I
Holdings and GAF Building Materials Corporation have agreed to indemnify BMCA,
relate primarily to closed manufacturing facilities. G-I Holdings estimates
that, as of December 31, 1999, its liability in respect of the environmental
liabilities of GAF Building Materials Corporation not assumed by BMCA was
approximately $10.5 million, before insurance recoveries reflected on its
balance sheet of $8.6 million. BMCA estimates its liability as of December 31,
1999 in respect of assumed and other environmental liabilities is $0.8 million,
and expects insurance recoveries reflected on its balance sheet, as discussed
below, of $0.8 million. Insurance recoveries reflected on these balance sheets
relate to both past expenses and estimated future liabilities. We refer to these
recoveries below as "estimated recoveries".

At most sites, BMCA anticipates that liability will be apportioned among
the companies found to be responsible for the presence of hazardous substances
at the site. Although it is difficult to predict the ultimate resolution of
these claims, based on BMCA's evaluation of the financial responsibility of the
parties involved and their insurers, relevant legal issues and cost sharing
arrangements now in place, BMCA estimates that its liability in respect of all
Environmental Claims, including certain environmental compliance expenses, will
be as discussed above. For information relating to other environmental
compliance expenses, see Item 1, "Business--Environmental Compliance."

After considering the relevant legal issues and other pertinent factors,
BMCA believes that it will receive the estimated recoveries and the legal
expenses incurred by GAF Corporation on BMCA's behalf. We also believe that
recoveries could be well in excess of the estimated recoveries for all
Environmental Claims, although there can be no assurances in this regard. BMCA
believes it is entitled to substantially full defense and indemnity under its
insurance policies for most Environmental Claims, although BMCA's insurers have
not affirmed a legal obligation under the policies to provide indemnity for
those claims.

In March 1995, GAF Corporation commenced litigation on behalf of itself and
its predecessors, successors, subsidiaries and related corporate entities in the
United States District Court for the District of New Jersey seeking amounts
substantially in excess of the estimated recoveries. The court dismissed this
action in December 1997 for lack of federal jurisdiction, and defendant insurers
appealed the dismissal. The appeal was denied by the Third Circuit Court of
Appeals in March 1999. In June 1997, GAF Corporation

filed a similar action against the insurers in the Superior Court of New Jersey,
Somerset County, which action is pending. While BMCA believes that its claims
are meritorious, there can be no assurance that BMCA will prevail in its efforts
to obtain amounts equal to, or in excess of, the estimated recoveries.

We believe that we will not sustain any liability for environmental
liabilities of GAF Building Materials Corporation other than those that we have
contractually assumed or that relate to the operations of our business. While we
cannot predict whether any claims for non-assumed environmental liabilities will
be asserted against us or our assets, or the outcome of any litigation relative
to those claims, we believe that we have meritorious defenses to those claims.
In addition, G-I Holdings and GAF Building Materials Corporation have jointly
and severally indemnified us with respect to those claims. G-I Holdings has
advised us that it believes it has and will have sufficient resources to enable
it to satisfy these indemnification obligations, if any. For the possible
consequences to us of the failure of G-I Holdings and GAF Building Materials
Corporation to satisfy judgments against them in environmental-related lawsuits
or otherwise, see the last paragraph of "--Bodily Injury Claims" above.

OTHER LITIGATION

Litigation is pending between us and Elk Corporation of Dallas in the
United States District Court for the Northern District of Texas relating to
certain aspects of our laminated shingles, which Elk claims infringe design and
utility patents issued to it. Elk also asserts that we have appropriated the
trade dress of Elk's product. Elk seeks injunctive relief, damages and
attorneys' fees. We have sued for a declaration that Elk's patents are invalid
and unenforceable and that our shingles do not infringe any of Elk's rights, and
have sought money damages for Elk's unfair competition. On October 10, 1997, the
court issued an opinion holding that Elk's design patent is unenforceable
because it was obtained through inequitable conduct. On February 11, 1999, the
United States Court of Appeals for the Federal Circuit affirmed the lower
court's ruling of enforceability. Elk filed a petition for rehearing on February
25, 1999, which was denied by the court, and subsequently filed a petition for a
writ of certiorari in the United States Supreme Court, which also was denied. We
believe that we will prevail on Elk's remaining claims in the United States
District Court.

On or about April 29, 1996, an action was commenced in the Circuit Court of
Mobile County, Alabama against GAF Building Materials Corporation on behalf of a
purported nationwide class of purchasers of, or current owners of, buildings
with certain asphalt shingles manufactured by GAF Building Materials
Corporation. The action alleged, among other things, that those shingles were
defective and sought unspecified damages on behalf of the purported class. On
September 25, 1998, we agreed to settle this litigation on a national,
class-wide basis for asphalt shingles manufactured between January 1, 1973 and
December 31, 1997. Following a fairness hearing, the court granted final
approval of the class-wide settlement in April 1999. Under the terms of the
settlement, we will provide property owners whose shingles were manufactured
during this period and which suffer certain damages during the term of their
original warranty period, and who file a qualifying claim, with an opportunity
to receive certain limited benefits beyond those already provided in their
existing warranty. In October and December 1998, the separate actions commenced
in 1997 in the Superior Court of New Jersey, Middlesex County, the Superior
Court of New Jersey, Passaic County and the Supreme Court of the State of New
York, County of Nassau, and in 1996 in Pointe Coupee Parish, Louisiana, on
behalf of purported classes alleging that our shingles were defective and
seeking unspecified damages, were stayed pending the outcome of the fairness
hearing on the settlement agreement in the Mobile County, Alabama action. The
Middlesex County, New Jersey and the Pointe Coupee Parish, Louisiana actions
have been dismissed in light of the final approval of the settlement agreement
in the Mobile County, Alabama action, and we expect that the remaining two
actions also will be dismissed.

In October 1998, GAF Corporation brought suit in the Superior Court of New
Jersey, Middlesex County, on behalf of itself and on our behalf, against certain
of its insurers for recovery of the defense costs in connection with the Mobile
County, Alabama class action and a declaration that the insurers are obligated
to provide indemnification for all damages paid pursuant to the settlement of
this class action and for other damages. This action is pending.

We believe that the ultimate disposition of the cases described above under
"Environmental Litigation," "Asbestos-in-Building Claims" and "Other Litigation"
will not, individually or in the aggregate, have a material adverse effect on
our liquidity, financial position or results of operations.

TAX CLAIM AGAINST GAF CORPORATION

On September 15, 1997, GAF Corporation received a notice from the Internal
Revenue 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., a partnership in which GAF
Fiberglass held an interest. The claim of the IRS for interest and penalties,
after taking into account the effect on the use of net operating losses and
foreign tax credits, could result in GAF Corporation incurring liabilities
significantly in excess of the deferred tax liability of $131.4 million that it
recorded in 1990 in connection with this matter. GAF Corporation has advised us
that it believes that it will prevail in this matter, although we cannot assure
you that will be the result. We believe that the ultimate disposition of this
matter will not have a material adverse effect on our business, financial
position or results of operations. GAF, G-I Holdings and certain subsidiaries of
GAF Corporation have agreed to jointly and severally indemnify us against any
tax liability associated with the surfactants partnership, for which we would be
severally liable, together with GAF Corporation and several current and former
subsidiaries of GAF Corporation, should GAF Corporation be unable to satisfy
this liability. For the possible consequences to us of the failure of GAF
Corporation to satisfy this liability and other information relating to GAF, see
the last paragraph of "--Bodily Injury Claims" above.

(1) The BMCA preferred stock options represent options to purchase shares of
redeemable convertible preferred stock of BMCA. Each share of preferred
stock is convertible, at the holder's option, into shares of Class A common
stock of BMCA at a formula price based on Book Value (as defined in the
option agreement) as of the date of grant. The options vest over five years
from the date of grant. Dividends will accrue on the preferred stock from
the date of issuance at the rate of 6% per annum. The preferred stock is
redeemable, at BMCA's option, for a redemption price equal to the exercise
price per share plus accrued and unpaid dividends. The Class A common stock
of BMCA issuable upon conversion of the preferred stock is subject to
repurchase by BMCA under certain circumstances at a price equal to its then
current Book Value. The exercise price of the options is equal to the fair
value per share of the preferred stock at the date of grant. The options
expire nine years after the date of grant.

(1) None of the options for 6,453 shares of preferred stock held by Mr. Weinberg
were exercisable at December 31, 1999. The stock appreciation rights
relating to GAF Corporation common stock represent the right to receive a
cash payment based upon the appreciation in value of the specified number of
shares of common stock of GAF Corporation over the determined initial book
value per share of common stock of GAF Corporation, adjusted for the
separation transactions, and interest on such book value at a specified
rate. The GAF Corporation stock appreciation rights vest over a five-year
period, subject to earlier vesting under certain circumstances, including in
connection with a change of control, and have no expiration date.
(2) Options for 12,118, 8,037, 0 and 10,846 shares of preferred stock were

December 31, 1999. None of the options for 6,453 shares of preferred stock
held by Mr. Weinberg were in-the-money at December 31, 1999.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

MANAGEMENT AGREEMENTS

Pursuant to a management agreement which expires December 31, 2000,
International Specialty Products Inc. (of which our Chairman and Chief Executive
Officer, Samuel J. Heyman, beneficially owns (as defined in Rule 13d-3 of the
Exchange Act) approximately 76%) provides certain general management,
administrative, legal, telecommunications, information and facilities services
to us, including the use of our headquarters in Wayne, New Jersey. ISP charged
us $5.3 million in 1999 for providing these services. These charges consist of
management fees and other reimbursable expenses attributable to us, or incurred
by ISP for our benefit. They are based on an estimate of the costs ISP incurs to
provide such services. Effective January 1, 2000, the term of the management
agreement was extended through the end of 2000, and the management fees payable
under the agreement were increased. We also allocate a portion of the management
fees payable by us under the management agreement to separate lease payments for
the use of our headquarters. Based on the services provided by ISP in 1999 under
the management agreement, the aggregate amount payable by us to ISP under the
management agreement for 2000 is expected to be approximately $6.0 million.
Certain of our executive officers receive their compensation from ISP. ISP is
indirectly reimbursed for this compensation through payment of the management
fee and other reimbursable expenses payable under the management agreement.

As of January 1, 1997, we entered into a separate management agreement with
GAF Fiberglass under which we provided certain general management,
administrative and financial services to GAF Fiberglass. Under the management
agreement, which terminated upon the August 1999 contribution by GAF Fiberglass
to us of certain assets, including our Nashville glass fiber manufacturing
facility, and certain related liabilities, GAF Fiberglass paid to us
approximately $0.7 million as a management fee in 1999.

Due to the unique nature of the services provided under the management
agreements, comparisons with third party arrangements are difficult. However, we
believe that the terms of each of the management agreements taken as a whole are
no less favorable to us than could be obtained from an unaffiliated third party.

CERTAIN PURCHASES

We purchase all of our colored roofing granules requirements from ISP under
a requirements contract, except for the requirements of our California and
Oregon roofing plants and a portion of the requirements of our Indiana roofing
plant, which are supplied by a third party. Effective January 1, 1999, this
contract was amended to cover, among other things, purchases of colored roofing
granules by our subsidiaries. This contract is subject to annual renewal, unless
terminated by either party to the agreement. In 1999, BMCA and its subsidiaries
purchased in the aggregate approximately $57.3 million of mineral products from
ISP.

Effective August 18, 1999, GAF Fiberglass, in a series of transactions,
contributed to us certain assets, including the Nashville glass fiber
manufacturing facility, and certain related liabilities. Prior to this
contribution, GAF Fiberglass manufactured a significant portion of our glass
fiber requirements pursuant to a supply agreement on terms which we believe were
at least as favorable to us as could be obtained from an unaffiliated third
party. We purchased approximately $19.6 million of glass fiber from GAF
Fiberglass in 1999.

TAX SHARING AGREEMENT

We have entered into a tax sharing agreement dated January 31, 1994 with
GAF Corporation and G-I Holdings with respect to the payment of federal income
taxes and certain related matters. During the term of the tax sharing agreement,
which is effective for the period during which we or any of our domestic
subsidiaries is included in a consolidated federal income tax return filed by
GAF Corporation, we are obligated to pay G-I Holdings an amount equal to those
federal income taxes we would have incurred if we, on behalf of ourselves and
our domestic subsidiaries, filed our own federal income tax return. Unused tax
attributes will carry forward for use in reducing amounts payable by us to G-I
Holdings in future years, but cannot be carried back. If we ever were to leave
the GAF Corporation consolidated tax group, we would be

17

required to pay to G-I Holdings the value of any tax attributes to which we
would succeed under the consolidated return regulations to the extent the tax
attributes reduced the amounts otherwise payable by us under the tax sharing
agreement. Under certain circumstances, the provisions of the tax sharing
agreement could result in us having a greater liability under the agreement than
we would have had if we and our domestic subsidiaries had filed our own separate
federal income tax return. Under the tax sharing agreement, we and each of our
domestic subsidiaries are responsible for any taxes that would be payable by
reason of any adjustment to the tax returns of GAF Corporation or its
subsidiaries for years prior to the adoption of the tax sharing agreement that
relate to our business or assets or the business or assets of any of our
domestic subsidiaries. Although, as a member of the GAF tax group, we are
severally liable for all federal income tax liabilities of the GAF tax group,
including tax liabilities not related to our business, G-I Holdings and GAF
Corporation have agreed to indemnify us and our subsidiaries for all tax
liabilities of the GAF tax group other than tax liabilities arising from our
operations and the operations of our domestic subsidiaries and tax liabilities
for tax years pre-dating the tax sharing agreement that relate to our business
or assets and the business or assets of any of our domestic subsidiaries. See
Item 3, "Legal Proceedings--Bodily Injury Claims." The tax sharing agreement
provides for analogous principles to be applied to any consolidated, combined or
unitary state or local income taxes. Under the tax sharing agreement, GAF
Corporation makes all decisions with respect to all matters relating to taxes of
the GAF tax group. The provisions of the tax sharing agreement take into account
both the federal income taxes we would have incurred if we filed our own
separate federal income tax return and the fact that we are a member of the GAF
tax group for federal income tax purposes.

INTERCOMPANY BORROWINGS

BMCA makes loans to, and borrows from, G-I Holdings and its subsidiaries
from time to time at prevailing market rates. No loans were made by BMCA to G-I
Holdings during 1999, and no loans were made to BMCA by G-I Holdings and its
subsidiaries during 1999. As of December 31, 1999, no loans were owed to BMCA by
G-I Holdings, and no loans were owed by BMCA to affiliates. In addition, BMCA
makes non-interest bearing advances to affiliates, of which $59.1 million were
outstanding at December 31, 1999. In 1999, BMCA made a distribution of
$60.0 million to its parent company. See Note 14 to Consolidated Financial
Statements.

BUILDING MATERIALS CORPORATION OF AMERICA

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

Building Materials Corporation of America (the "Company"), an indirect
subsidiary of GAF Corporation ("GAF") and G-I Holdings Inc. ("G-I Holdings"),
was formed in January 1994 to acquire the operating assets and certain
liabilities of GAF Building Materials Corporation ("GAFBMC"), a parent of the
Company. See Note 1 to Consolidated Financial Statements.

RESULTS OF OPERATIONS

1999 Compared With 1998

The Company recorded net income in 1999 of $24.0 million compared with a
net loss of $9.8 million in 1998. The net income in 1999 and the net loss in
1998 included pre-tax nonrecurring charges of $2.7 million ($1.7 million
after-tax) and $27.6 million ($17.1 million after-tax), respectively, and
after-tax extraordinary losses of $1.3 million and $18.1 million, respectively.
Excluding the extraordinary losses and nonrecurring charges in both years, net
income would have been $27.0 million in 1999 compared with $25.4 million in
1998, an increase of 6.3%, with the increase primarily attributable to higher
operating income and lower interest expense, partially offset by lower
investment income.

Net sales for 1999 were $1,140.0 million, a 4.8% increase over net sales
for 1998 of $1,088.0 million. The sales growth was primarily due to the
inclusion of the LL Building Products Inc. business, acquired in June 1998, for
the full year (see Note 4 to Consolidated Financial Statements), together with
net sales gains in premium residential roofing products, partially offset by
lower net sales in commercial roofing products. The increase in net sales of
premium residential roofing products resulted from higher sales volumes and
average selling prices, while the decline in net sales of commercial roofing
products resulted from lower average selling prices.

Operating income, before the impact of nonrecurring charges, for 1999 was
$85.7 million, a 14.2% increase over the $75.1 million for 1998 and, as a
percentage of sales, improved to 7.5% in 1999 from 6.9% in 1998. The increase in
operating income in 1999 was primarily attributable to higher net sales for the
Company's premium residential roofing products, the inclusion of the LL Building
Products Inc. business, acquired in June 1998, for the full year, and a modest
improvement in commercial roofing products, primarily the result of lower
selling, general and administrative expenses and manufacturing costs.

The Company recorded pre-tax nonrecurring charges in 1999 of $2.7 million
related to the settlement of a legal matter and, in 1998, $27.6 million, of
which $20.0 million related to the settlement of a national class action lawsuit
involving asphalt shingles, and $7.6 million related to a grant to the Company's
former President and Chief Executive Officer of restricted common stock of the
Company and certain cash payments to be made over a specified period of time
(substantially all of which was earned) in connection with the termination by an
affiliate of preferred stock options and stock appreciation rights held by such
officer (see Note 5 to Consolidated Financial Statements).

Interest expense declined to $48.3 million for 1999 from $50.0 million in
1998, due primarily to a lower average interest rate, partially offset by higher
average borrowings. The lower average interest rate resulted primarily from the
refinancing of $310 million in aggregate principal amount at maturity of the
Company's 11 3/4% Senior Deferred Coupon Notes due 2004 (the "Deferred Coupon
Notes") with substantially all of the net proceeds from the issuances of
$150 million in aggregate principal amount of the Company's 7 3/4% Senior Notes
due 2005 (the "2005 Notes"), $155 million in aggregate principal amount of the
Company's 8% Senior Notes due 2008 (the "2008 Notes") and a $31.9 million Term
Loan (the "Term Loan") in July 1998, December 1998 and August 1999,
respectively. In connection with the above refinancing, the Company recorded
after-tax extraordinary losses of $1.3 million in 1999 and $18.1 million in 1998
related to premiums paid to repurchase the Deferred Coupon Notes.

Other income, net, was $5.4 million in 1999 compared with $15.9 million in
1998. The decline was principally due to $10.3 million lower investment income.

F-2

1998 Compared With 1997

The Company recorded a net loss in 1998 of $9.8 million compared with net
income of $27.8 million in 1997. The net loss in 1998 reflected the impact of
$27.6 million of pre-tax nonrecurring charges ($17.1 million after-tax) and
after-tax extraordinary losses of $18.1 million. Excluding the effect of these
charges and losses, the Company's results reflected higher operating and other
income, partially offset by increased interest expense.

Net sales for 1998 were $1,088.0 million, a 15.2% increase over net sales
for 1997 of $944.6 million, principally due to increased sales in the
residential roofing products and the acquisition of the LL Building Products
Inc. business in June 1998 (see Note 4 to Consolidated Financial Statements),
partially offset by lower sales in commercial roofing products. The increase in
residential roofing sales resulted from higher unit volumes and average selling
prices, while the commercial roofing products experienced declines in both unit
volumes and average selling prices.

Operating income, before the impact of the nonrecurring charges, was
$75.1 million for 1998, a 2.6% increase over the $73.2 million recorded in 1997.
This increase in operating income was primarily attributable to improved gross
profit margins due to increased plant capacity utilization and the inclusion of
the LL Building Products Inc. business after its acquisition in June 1998.
Partially offsetting these improvements were higher distribution costs due to
rail carrier service problems in the first nine months of 1998 and higher
selling, general and administrative expenses resulting from broader marketing
efforts.

The Company recorded pre-tax nonrecurring charges in 1998 (see Note 5 to
Consolidated Financial Statements) aggregating $27.6 million, of which
$20.0 million related to the settlement of a national class action lawsuit
involving asphalt shingles manufactured between January 1, 1973 and
December 31, 1997. Under the terms of the September 1998 settlement, the Company
will provide property owners whose GAF shingles were manufactured during this
period and which suffer certain damages during the term of their original
warranty period, and who file a qualifying claim, with an opportunity to receive
certain limited benefits beyond those already provided in their existing
warranty. In July 1998, the Company recorded a pre-tax nonrecurring charge of
$7.6 million related to a grant to its President and Chief Executive Officer of
30,000 shares of restricted common stock of the Company and related cash
payments to be made over a specified period of time (substantially all of which
was earned) in connection with the termination by an affiliate of preferred
stock options and stock appreciation rights held by such officer.

Interest expense increased from $43.0 million in 1997 to $50.0 million in
1998, primarily due to higher debt levels, partially offset by a lower average
interest rate. The lower average interest rate resulted from the refinancing of
$279.7 million in aggregate principal amount at maturity of the Company's
Deferred Coupon Notes with substantially all of the net proceeds from the
issuances of the 2005 Notes and the 2008 Notes in July and December 1998,
respectively. See the discussion below under Liquidity and Financial Condition.
In connection with these transactions, the Company recorded after-tax
extraordinary losses of $18.1 million related to premiums paid to purchase the
Deferred Coupon Notes.

Other income, net, was $15.9 million in 1998 compared with $15.5 million in
1997, with the improvement due primarily to the absence of a $3.0 million
provision recorded in 1997 for estimated obligations related to product warranty
claims for a discontinued product, and lower other miscellaneous expenses,
partially offset by $4.2 million lower investment income.

LIQUIDITY AND FINANCIAL CONDITION

Net cash inflow during 1999 was $84.8 million before financing activities,
and included $82.5 million of cash generated from operations, the reinvestment
of $45.3 million for capital programs, and the generation of $48.2 million from
net sales of available-for-sale and held-to-maturity securities and other
short-term investments.

Cash invested in additional working capital (excluding the non-cash leasing
transactions described below) totaled $26.2 million during 1999, primarily
reflecting increases in accounts receivable and inventories of $11.3 and
$14.9 million, respectively, and a decrease in accrued liabilities of $11.3
million (after non-cash transactions), partially offset by a $9.9 million
increase in accounts payable. Cash from operating activities also reflected a
$48.8 million cash outflow from related party transactions (net of a
$60 million distribution to parent

F-3

company), a $103.6 million cash inflow from net sales of trading securities, a
$14.3 million cash outflow for product warranty claims and $10.2 million of cash
outflow from a decrease in other assets, other liabilities and other operating
activities, including $2.2 million of capitalized software.

In connection with the construction of two new manufacturing facilities,
the Company entered into two leases for certain machinery and equipment to be
utilized at the Company's plants under construction in Michigan City, Indiana
and Shafter, California, which leases meet the criteria of operating leases
under Statement of Financial Accounting Standards ("SFAS") No. 13 "Accounting
for Leases". In connection therewith, at December 31, 1999, property, plant and
equipment, net, and accrued liabilities included $65.6 million of assets under
such leases. Such amounts will be reversed when the related plants become fully
operational, which is expected to occur in 2000. This $65.6 million increase in
accrued liabilities was offset by other reductions aggregating $10.4 million.

Net cash used in financing activities totaled $53.9 million in 1999. The
Company generated $5.6 million of proceeds from the sale of the Company's trade
receivables and $37.9 million of proceeds from the issuance of long-term debt,
including $31.9 million from the Term Loan used to refinance the remaining
amount of Deferred Coupon Notes outstanding, $3.5 million from an industrial
revenue bond and $1.8 million from a promissory note. Offsetting such cash
inflows was $36.0 million of repayments of long-term debt, principally the
repurchase of the remaining $29.9 million in aggregate principal amount of the
Deferred Coupon Notes, a $60.0 million distribution to parent company, and $2.4
million in financing fees and expenses.

As a result of the foregoing factors, cash and cash equivalents increased
by $31.0 million during 1999 to $56.0 million, excluding $32.0 million of
trading and available-for-sale securities and other short-term investments.

In August 1999, the Company entered into a new three-year bank credit
facility (the "Credit Agreement"). The terms of the Credit Agreement provide for
a $110 million revolving credit facility, the full amount of which is available
for letters of credit, provided that total borrowings and outstanding letters of
credit may not exceed $110 million in the aggregate. As of December 31, 1999,
$27.1 million of letters of credit and no borrowings were outstanding under the
Credit Agreement. Under the terms of the Credit Agreement, the Company is
subject to certain financial covenants, including interest coverage and leverage
ratios, along with a limitation on the amount of dividends and other restricted
payments made to affiliates. As of December 31, 1999, the Company was in
compliance with all such covenants.

Additional borrowings by the Company are subject to certain covenants
contained in the indentures relating to the 8 5/8% Senior Notes due 2006, the 8%
Senior Notes due 2007, the 2005 Notes, the 2008 Notes (collectively, the "Other
Senior Notes"), the Credit Agreement and the Term Loan.

See Note 10 to Consolidated Financial Statements for further information
regarding the debt instruments of the Company.

Upon its formation on January 31, 1994, the Company assumed the first
$204.4 million of GAFBMC's liabilities relating to then-pending cases and
previously settled asbestos-related bodily injury cases, all of which were paid
as of March 30, 1997. See Item 3, "Legal Proceedings" for further information
regarding asbestos-related matters. At December 31, 1999, the Company had total
outstanding consolidated indebtedness of $606.9 million, of which $6.1 million
matures prior to December 31, 2000, and stockholders' equity of $21.7 million.
The Company anticipates funding such obligations principally from its cash and
investments, operations and/or borrowings, which may include borrowings from
affiliates.

In March 1993, the Company sold its trade accounts receivable
("receivables") to a trust, without recourse, pursuant to an agreement which
provided for a maximum of $75 million in cash to be made available to the
Company based on eligible receivables outstanding from time to time. In November
1996, the Company repurchased the receivables sold pursuant to the 1993
agreement and sold them to a special purpose subsidiary of the Company, BMCA
Receivables Corporation, without recourse, which in turn sold them to a new
trust, without recourse, pursuant to new agreements. The new agreements provide
for a maximum of $115 million in cash to be made available to the Company based
on eligible receivables outstanding from time to time. This facility expires in
December 2001.

F-4

The Company makes loans to, and borrows from, G-I Holdings and its
subsidiaries at prevailing market rates. As of December 31, 1999, no loans were
owed to the Company by G-I Holdings and no loans were owed by the Company to
affiliates. In addition, the Company makes non-interest bearing advances to
affiliates, of which $59.1 million were outstanding at December 31, 1999.

The parent corporations of the Company are essentially holding companies
without independent businesses or operations and, as such, are presently
dependent upon the earnings and cash flows of their subsidiaries, principally
the Company, in order to satisfy their obligations, including asbestos-related
and other claims and certain potential tax liabilities including tax liabilities
relating to Rhone-Poulenc Surfactants & Specialties, L.P., a Delaware limited
partnership which operates, among other businesses, GAF Fiberglass Corporation's
("GFC") former surfactants chemicals business. The parent corporations of the
Company are GAF, G-I Holdings, G Industries Corp., GFC, GAFBMC and BMCA Holdings
Corporation. GAF has advised the Company that it expects to obtain funds to
satisfy such obligations from, among other things, dividends and loans from
subsidiaries, principally the Company, payments pursuant to the Tax Sharing
Agreement between GAF and the Company and proceeds from insurance recoveries.
The indentures relating to the Other Senior Notes, the Credit Agreement and the
Term Loan contain restrictions on the amount of dividends, loans and other
restricted payments, as defined therein, which may be paid by the Company. As of
December 31, 1999, after giving effect to the most restrictive of the
aforementioned restrictions, the Company could have paid dividends and other
restricted payments of up to $76.1 million. The Company does not believe that
the dependence of its parent corporations on the cash flows of their
subsidiaries should have a material adverse effect on the operations, liquidity
or capital resources of the Company. For further information, see Notes 3, 6,
10, 14 and 15 to Consolidated Financial Statements.

The Company uses capital resources to maintain existing facilities, expand
its operations and make acquisitions. In 2000, the Company expects to complete
construction of a new fiberglass roofing mat manufacturing facility in Shafter,
California and a new residential roofing shingle manufacturing facility in
Michigan City, Indiana. In addition, the Company expects to build a
manufacturing facility for a single ply commercial membrane roofing system in
2000. Funding for the Company's capital program is expected to be generated from
results of operations and leasing transactions.

The Company utilizes interest rate swap agreements ("swaps") to lower
funding costs, diversify sources of funding and manage interest rate exposure.
In June 1998, the Company terminated its outstanding swaps related to its
Deferred Coupon Notes with an aggregate ending notional principal amount of
$60.0 million, resulting in gains of $0.7 million. The gains were deferred and
amortized as a reduction of interest expense over the remaining original life of
the swaps. By utilizing swaps, the Company reduced its interest expense by $2.0,
$1.9 and $0.2 million in 1997, 1998 and 1999, respectively. See Note 10 to
Consolidated Financial Statements.

The Company does not believe that inflation has had an effect on its
results of operations during the past three years. However, there can be no
assurance that the Company's business will not be affected by inflation in the
future, or by the increase in cost of asphalt purchases used in the Company's
manufacturing process principally due to rising oil prices.

Market-Sensitive Instruments and Risk Management

The Company's investment strategy is to seek returns in excess of money
market rates on its available cash while minimizing market risks. There can be
no assurance that the Company will be successful in implementing such a
strategy. The Company invests primarily in international and domestic arbitrage
and securities of companies involved in acquisition or reorganization
transactions, including at times, common stock short positions which are offset
against long positions in securities which are expected, under certain
circumstances, to be exchanged or converted into the short positions. With
respect to its equity positions, the Company is exposed to the risk of market
loss. See Note 2 to Consolidated Financial Statements.

F-5

The Company enters into financial instruments in the ordinary course of
business in order to manage its exposure to market fluctuations on its
short-term investments. The financial instruments the Company employs to reduce
market risk include hedging instruments. The counterparties to these financial
instruments are major financial institutions with high credit standings. The
amounts subject to credit risk are generally limited to the amounts, if any, by
which the counterparties' obligations exceed the obligations of the Company. The
Company controls credit risk through credit approvals, limits and monitoring
procedures. The Company does not anticipate nonperformance by counterparties to
these instruments.

All of the financial instruments in the above table have a maturity of less
than one year. As of December 31, 1999, equity-related financial instruments
employed by the Company to reduce market risk include long contracts valued at
$0.9 million, which are marked-to-market each month, with unrealized gains and
losses included in results of operations. As such, there is no economic cost at
December 31, 1999 to terminate these instruments and therefore the fair market
value is zero.

Year 2000 Compliance

During 1999, the Company completed a formal year 2000 program (the "Year
2000 Program") to address the potential issues relating to the inability of some
of its information technology ("IT") and non-IT equipment, including embedded
technology, to accurately read and process certain dates, including dates in the
year 2000 and afterwards (the "Year 2000 Issues"). As part of the Year 2000
Program, the Company also requested information on the Year 2000 Issues of third
parties significant to the Company's business and, accordingly, developed
contingency plans to minimize the impact of Year 2000 Issues on its business.
The costs to complete the Year 2000 Program were not material to the Company's
financial position or results of operations. To date, the Company has not
experienced any significant consequences related to Year 2000 Issues, and the
Company reasonably believes that potential undiscovered Year 2000 Issues will
not have a material effect on its business, financial condition or results of
operations.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Building Materials Corporation of America:

We have audited the accompanying consolidated balance sheets of Building
Materials Corporation of America (a Delaware corporation) and subsidiaries as of
December 31, 1998 and 1999, and the related consolidated statements of
operations, stockholders' equity and cash flows for each of the three years in
the period ended December 31, 1999. These financial statements and the schedule
referred to below are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above, appearing on
pages F-9 to F-40 of this Form 10-K, present fairly, in all material respects,
the financial position of Building Materials Corporation of America and
subsidiaries as of December 31, 1998 and 1999, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1999, in conformity with generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule appearing on page S-1 of
this Form 10-K is presented for the purpose of complying with the Securities and
Exchange Commission's rules and is not part of the basic financial statements.
This schedule has been subjected to the auditing procedures applied in the audit
of the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

BUILDING MATERIALS CORPORATION OF AMERICA

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Building Materials Corporation of America (the "Company") was formed on
January 31, 1994 and is a 99.6%-owned subsidiary of BMCA Holdings Corporation
("BHC"), which is a 97%-owned subsidiary of GAF Building Materials Corporation
("GAFBMC"), which is a wholly-owned subsidiary of GAF Fiberglass Corporation
("GFC"), which is a wholly-owned subsidiary of G Industries Corp. ("G
Industries"), which is a wholly-owned subsidiary of G-I Holdings Inc. ("G-I
Holdings"), which is a wholly-owned subsidiary of GAF Corporation ("GAF").

NOTE 1. FORMATION OF THE COMPANY

Effective as of January 31, 1994, GAFBMC transferred to the Company all of
its business and assets, other than three closed manufacturing facilities,
certain deferred tax assets and receivables from affiliates. The Company
recorded the assets and liabilities related to such transfer at GAFBMC's
historical costs. The Company contractually assumed all of GAFBMC's liabilities,
except (i) all of GAFBMC's environmental liabilities, other than environmental
liabilities relating to the Company's plant sites and its business as
then-conducted, (ii) all of GAFBMC's tax liabilities, other than tax liabilities
arising from the operations or business of the Company and (iii) all of GAFBMC's
asbestos-related liabilities, other than the first $204.4 million of such
liabilities (whether for indemnity or defense) relating to then-pending
asbestos-related bodily injury cases and previously settled asbestos-related
bodily injury cases which the Company contractually assumed and agreed to pay.
G-I Holdings and GAFBMC have agreed, jointly and severally, to indemnify the
Company from liabilities not assumed by the Company, including asbestos-related
and environmental liabilities not expressly assumed by the Company. See Note 3.

In October 1995, G-I Holdings acquired all of the outstanding shares of
U.S. Intec, Inc. ("U.S. Intec"), which manufactures commercial roofing products,
for a purchase price of $27.5 million and assumed $35.0 million of U. S. Intec's
indebtedness. As of January 1, 1997, U.S. Intec became a wholly-owned subsidiary
of the Company through a capital contribution to the Company by G-I Holdings.
Accordingly, the Company's historical consolidated financial statements include
U.S. Intec's results of operations and cash flows from the date of its
acquisition by G-I Holdings (October 20, 1995). The Company recorded the assets
and liabilities of U.S. Intec at G-I Holdings' purchase accounting basis.

On January 1, 1997, GAF effected a series of transactions involving its
subsidiaries (the "Separation Transactions") that resulted in, among other
things, (i) the approximately 83.5% of the issued and outstanding common stock
of International Specialty Products Inc. ("ISP"), an affiliate, owned by a
subsidiary of GAF, being distributed to ISP Holdings Inc., a subsidiary of GAF,
and the capital stock of ISP Holdings being distributed to the stockholders of
GAF, (ii) the Company's glass fiber manufacturing facility in Nashville,
Tennessee (the "Nashville facility"), and certain related assets and
liabilities, being transferred to GAF Fiberglass Corporation ("GFC"),
(iii) U.S. Intec becoming a subsidiary of the Company and (iv) G-I Holdings
making a contribution to the Company in December 1996 of $82.5 million in cash
and short-term investments. As a result of the Separation Transactions, ISP
Holdings and ISP are no longer direct or indirect subsidiaries of GAF, while the
Company and GFC have remained subsidiaries of GAF. On July 15, 1998, ISP merged
with and into ISP Holdings and ISP Holdings changed its name to International
Specialty Products Inc. The Company recorded the transfer of the Nashville
facility as a distribution to its indirect parent, G-I Holdings, at its net book
value. G-I Holdings then made a capital contribution to GFC equal to such net
book value.

Effective August 18, 1999, GFC, in a series of transactions, contributed
certain assets, including the Nashville facility, and certain related
liabilities to the Company. Accordingly, the Company's historical consolidated
financial statements for 1997 and 1998 have been restated to include the results
of operations, cash flows and assets and liabilities of the Nashville facility.
The Nashville facility was included in the Company's financial statements prior
to 1997. For financial reporting purposes, the contribution of the Nashville
facility was recorded by the Company at the historical cost of $9.3 million. The
increase in net income resulting from the contribution of the Nashville facility
for the years ended December 31, 1997 and 1998 was $1.7 and $0.8 million,
respectively.

NOTE 1. FORMATION OF THE COMPANY--(CONTINUED)

The parent corporations of the Company are GAF, G-I Holdings, G Industries,
GFC, GAFBMC and BHC. As a result of the Separation Transactions, dividends from
ISP are not available to GAF and G-I Holdings, and loans from ISP to GAF, G-I
Holdings and the Company are prohibited by certain of ISP's debt instruments.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

All subsidiaries are consolidated and intercompany transactions have been
eliminated.

Financial Statement Estimates

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates.
Actual results could differ from those estimates. In the opinion of management,
the financial statements herein contain all adjustments necessary to present
fairly the financial position and the results of operations and cash flows of
the Company for the periods presented. The Company has a policy to review the
recoverability of long-lived assets and identify and measure any potential
impairments. The Company does not anticipate any changes in management estimates
that would have a material impact on operations, liquidity or capital resources,
subject to the matters discussed in Note 15 (Commitments and Contingencies).

Short-term Investments

For securities classified as "trading" (including short positions),
unrealized gains and losses are reflected in income. For securities classified
as "available-for-sale," unrealized gains and losses, net of income tax effect,
are included in a separate component of stockholders' equity, "Accumulated other
comprehensive loss," and were $(16.9) and $(17.6) million as of December 31,
1998 and 1999, respectively. Investments classified as "held-to-maturity"
securities are carried at amortized cost in the Consolidated Balance Sheets.

"Other income, net" includes $26.4, $21.5 and $12.8 million of net realized
and unrealized gains on securities in 1997, 1998 and 1999, respectively. The
determination of cost in computing realized gains and losses is based on the
specific identification method.

As of December 31, 1998 and 1999, the market value of the Company's equity
securities held long was $172.5 and $30.5 million, respectively, and the Company
had $144.1 and $1.5 million, respectively, of short positions in common stocks,
based on market value. As of December 31, 1998 and 1999, the market value of the
Company's held-to-maturity securities was $6.4 million and $0, respectively. The
Company enters into equity-related financial instruments with off-balance-sheet
risk as a means to manage its exposure to market fluctuations on its short-term
investments. As of December 31, 1998 and 1999, the market value of
equity-related short contracts was $143.2 million and $0, respectively, while
the value of equity-related long contracts was $35.2 and $0.9 million,
respectively, both of which are marked-to-market each month, with unrealized
gains and losses included in results of operations. The market values referred
to above are based on quotations as reported by various stock exchanges and
major broker-dealers. With respect to its investments in securities, the Company
is exposed to the risk of market loss.

"Other short-term investments" are investments in limited partnerships
which are accounted for by the equity method. Gains and losses are reflected in
"Other income, net." Liquidation of partnership interests generally require a 30
to 45 day notice period.

Cash and cash equivalents include cash on deposit and debt securities
purchased with original maturities of three months or less.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)

Inventories

Inventories are stated at the lower of cost or market. The LIFO (last-in,
first-out) method is utilized to determine cost for a portion of the Company's
inventories. All other inventories are determined principally based on the FIFO
(first-in, first-out) method.

Property, Plant and Equipment

Property, plant and equipment is stated at cost less accumulated
depreciation. Depreciation is computed principally on the straight-line method
based on the estimated economic lives of the assets. The Company uses an
economic life of 5-25 years for land improvements, 10-40 years for buildings and
building equipment and 3-20 years for machinery and equipment, which includes
furniture and fixtures. Certain interest charges are capitalized during the
period of construction as part of the cost of property, plant and equipment.

Excess of Cost Over Net Assets of Businesses Acquired ("Goodwill")

Goodwill is amortized on the straight-line method over a period of
approximately 40 years. The Company believes that the goodwill is recoverable.
To determine if goodwill is recoverable, the Company compares the net carrying
amount to undiscounted projected cash flows of the underlying businesses to
which the goodwill pertains. If goodwill is not recoverable, the Company would
record an impairment based on the difference between the net carrying amount and
fair value.

Debt Issuance Costs

Debt issuance costs are amortized to expense over the life of the related
debt.

Software Development Costs

Included in other assets at December 31, 1998 and 1999 were $1.7 and
$3.3 million, respectively, of capitalized software development costs. Such
costs are amortized over a 5 year period. For 1998 and 1999, the Company
amortized $0.2 and $0.6 million, respectively, related to such costs.

Revenue Recognition

Revenue is recognized at the time products are shipped to the customer.

Interest Rate Swaps

Gains (losses) on interest rate swap agreements ("swaps") are deferred and
amortized as a reduction (increase) of interest expense over the shorter of the
remaining life of the swaps or the remaining period to maturity of the debt
issue with respect to which the swaps were entered.

Research and Development

Research and development expenses are charged to operations as incurred and
were $5.4, $6.0 and $6.5 million in 1997, 1998 and 1999, respectively.

Warranty Claims

The Company provides certain limited warranties covering most of its
residential roofing products for periods ranging from 20 to 40 years. The
Company also offers limited warranties and guarantees of varying duration on its
commercial roofing products and limited warranties covering most of its
specialty building products and accessories for periods ranging from 5 to 10
years. Income from warranty contracts related to

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)

commercial roofing products is recognized over the life of the agreements. The
Company believes that the reserves established for estimated probable future
warranty claims are adequate.

The Company's 1997 Consolidated Statement of Operations includes a
provision of $3.0 million in connection with the Company's estimated obligations
related to product warranty claims for a discontinued product. See also Note 5.

Environmental Liability

The Company, together with other companies, is a party to a variety of
proceedings and lawsuits involving environmental matters. The Company estimates
that its liability in respect of such environmental matters, and certain other
environmental compliance expenses, as of December 31, 1999, is $0.8 million,
before reduction for insurance recoveries reflected on its balance sheet of $0.8
million. The Company's liability is reflected on an undiscounted basis. See Item
3, "Legal Proceedings--Environmental Litigation," which is incorporated herein
by reference, for further discussion with respect to environmental liabilities
and estimated insurance recoveries.

Accumulated Other Comprehensive Income

In 1997, the Financial Accounting Standards Board (the "FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income," which establishes standards for reporting comprehensive
income and its components in annual and interim financial statements. In the
Company's case, comprehensive income includes net income, unrealized gains and
losses from investments in available-for-sale securities, net of income tax
effect, and minimum pension liability adjustments. The Company has chosen to
disclose comprehensive income in the Consolidated Statements of Stockholders'
Equity.

Changes in the components of "Accumulated other comprehensive income
(loss)" for the years 1997, 1998 and 1999 are as follows:



UNREALIZED GAINS MINIMUM ACCUMULATED

New Accounting Standard

In 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 establishes accounting and
reporting standards requiring that every derivative instrument be recorded in
the balance sheet as either an asset or liability measured at its fair value.
SFAS No. 133 requires that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. Special
accounting for qualifying hedges allows a derivative's gains and losses to
offset related results on the hedged item in the income statement.

SFAS No. 133, as amended by SFAS No. 137, is effective for fiscal years
beginning after June 15, 2000, but may be adopted earlier. The Company has not
yet determined the effect of adoption of SFAS No. 133 and has not determined the
timing or method of adoption of the statement.

Reclassifications

Certain reclassifications have been made to conform to current year
presentation.

NOTE 3. RESERVE FOR ASBESTOS-RELATED BODILY INJURY CLAIMS

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, GAFBMC. As of March 30, 1997, the Company had paid all
of its assumed asbestos-related liabilities. See also Note 1. G-I Holdings and
GAFBMC have jointly and severally agreed to indemnify the Company against any
other existing or future claims related to asbestos-related liabilities if
asserted against the Company.

GAF has advised the Company that, as of December 31, 1999, it is defending
approximately 115,000 pending alleged Asbestos Claims, having received notice of
approximately 43,100 new Asbestos Claims during 1999. GAF has advised that the
Center for Claims Resolution ("CCR"), a non-profit organization set up to
administer and handle asbestos-related personal injury claims against the
participating companies and in which GAF was a member, terminated GAF's
membership, effective January 17, 2000. GAF has advised the CCR that such
termination was unauthorized and that it intends to take appropriate measures to
protect its rights to pursue claims against the CCR and its member companies
arising out of this improper termination and for other improper actions.
Currently, the disputes between GAF and the CCR are the subject of pending
Alternative Dispute Proceedings.

GAF has confirmed that it has experienced a significant increase in the
rate of new Asbestos Claims, principally involving claimants without any
asbestos-related impairment, and amounts demanded to settle these claims. GAF
anticipates that these trends could well continue for the foreseeable future,
and that the percentage of Asbestos Claims filed by individuals with no physical
impairment will remain high. GAF has advised that it expects an increasingly
adverse litigation environment in particular jurisdictions. GAF believes that
these trends and the CCR's termination of GAF's membership resulted from, or
were induced by, in no small part, retaliatory actions taken by asbestos lawyers
against GAF in connection with GAF's active support of proposed legislation
currently pending in Congress to address the national asbestos litigation
crisis.

GAF has stated that it is committed to effecting a comprehensive resolution
of Asbestos Claims and that it is exploring options to accomplish such
resolution, including the support of the proposed Congressional legislation, but
there can be no assurance that these efforts 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 those claims, the Company believes
that it has meritorious defenses to any claim that could be so asserted. In
addition, G-I Holdings and GAFBMC have jointly and severally indemnified the
Company with respect to asbestos-related claims, and G-I Holdings has advised
the Company that it believes it has and will have sufficient resources to enable
it to satisfy any indemnification obligations. However, GAF has advised the
Company that depending upon whether the trends described above continue, whether
other retaliatory actions are taken, the ultimate resolution of the disputes
between GAF and the CCR, and whether the proposed legislation currently pending
in Congress is enacted into law, its financial condition could be materially
adversely affected by one or more of these factors. Should GAF or GAFBMC be
unable to satisfy judgments against it in asbestos-related lawsuits, its
judgment creditors might seek to enforce their judgments against the assets of
GAF, including its holdings of G-I Holdings common stock, or GAFBMC, including
its holdings of the Company's common stock. This enforcement could result in a
change of control with respect to the Company. See Notes 10 and 15 regarding the
Company's debt instruments and facilities and contingencies.

NOTE 4. ACQUISITIONS AND DISPOSITION

On March 14, 1997, the Company acquired the assets of the Leatherback
Industries division of Hollinee Corporation, which is engaged in the manufacture
and sale of asphalt-saturated felts and other felt and construction paper
products. The acquisition was accounted for under the purchase method of
accounting. Accordingly, the purchase price was allocated to the estimated fair
values of the identifiable net assets acquired, and the excess was recorded as
goodwill. The results of the Leatherback business, including net sales of
$30.2 million for 1997, are included from the date of acquisition. The net
effects of this acquisition were not material to 1997 results of operations.

Effective June 1, 1998, the Company purchased for approximately $43.5
million substantially all of the assets of Leslie-Locke Inc. ("LL Building
Products Inc."), a wholly-owned subsidiary of Leslie Building Products Inc.,
which manufactures and markets a variety of specialty building products and
accessories for the professional and do-it-yourself remodeling and residential
construction industries from manufacturing facilities in Burgaw, North Carolina
and Compton, California. The acquisition was accounted for under the purchase
method of accounting. Accordingly, the purchase price was allocated to the
estimated fair values of the identifiable net assets acquired, and the excess
was recorded as goodwill. The results of the LL Building Products Inc. business,
including net sales of $53.3 million for 1998, are included from the date of
acquisition. The net effects of this acquisition were not material to 1998
results of operations.

Effective December 1, 1998, the Company sold its perlite insulation
manufacturing assets to Johns Manville Corporation for net cash proceeds of
approximately $29.0 million. The pre-tax gain as a result of this sale was not
significant to the Company's results of operations. In addition, as part of the
transaction, Johns Manville and the Company entered into a long-term agreement
to supply the Company with perlite insulation products, which will enable the
Company to continue to serve its commercial roofing customers. As a result, the
sale did not have a material impact on the Company's results of operations.

NOTE 5. NONRECURRING CHARGES

The Company recorded pre-tax nonrecurring charges in the third quarter of
1998 aggregating $27.6 million, of which $20.0 million related to the settlement
of a national class action lawsuit involving asphalt shingles manufactured
between January 1, 1973 and December 31, 1997. Following a fairness hearing, the
court granted final approval of the class-wide settlement in April 1999. Under
the terms of the September 1998 settlement, the Company will provide property
owners whose GAF shingles were manufactured during this period and which suffer
certain damages during the term of their original warranty period, and who file
a qualifying claim, with an opportunity to receive certain limited benefits
beyond those already provided in their existing warranty. Two of the four
separate class actions that had been brought against GAFBMC and stayed pending
the outcome of the fairness hearing have been dismissed in light of the final
approval of the settlement agreement described above, and the Company expects
that the remaining two actions also will be dismissed.

In July 1998, the Company recorded a pre-tax nonrecurring charge of
$7.6 million related to a grant to its former President and Chief Executive
Officer of 30,000 shares of restricted common stock of the Company (a portion of
which such officer transferred to trusts for the benefit of his children) and
related cash payments to be made over a period of time (substantially all of
which was earned) in connection with the termination by an affiliate of
preferred stock options and stock appreciation rights held by such officer. Of
the $7.6 million charge, $2.5 million represented the value as of the date of
grant of the 30,000 shares of restricted common stock, and $5.1 million
represented the aggregate amount of the cash payments to which such officer was
entitled (subject to certain future vesting requirements). The shares of
restricted stock were subject to certain rights of the Company to purchase, and
of such officer and the trusts to sell to the Company, such shares at Book Value
(as defined).

F-19

BUILDING MATERIALS CORPORATION OF AMERICA

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

NOTE 5. NONRECURRING CHARGES--(CONTINUED)

Effective June 30, 1999, such officer terminated his employment with the
Company. For 1999, through the date of his termination, the net book value of
the 30,000 shares of restricted common stock held by such officer appreciated
$0.6 million. In connection with this termination, the Company's obligation to
such officer to pay an aggregate of $3.0 million (representing the balance of
the cash payments described above) was cancelled and was treated as an
additional capital contribution.

Effective September 30, 1999, the agreement between the Company and such
former officer and the trusts relating to the restricted common stock was
terminated. Such officer and the trusts contributed such stock to BHC in
consideration for equity interests in BHC. As a result of this transaction, the
$0.6 million appreciation in the net book value of the restricted common stock
described above, was treated as an additional capital contribution.

In connection with the settlement of a legal matter, the Company recorded a
nonrecurring charge of $2.7 million in September 1999. Such amount includes
legal expenses incurred to defend such action.

NOTE 6. INCOME TAXES

Income tax provision, which has been computed on a separate return basis,

As of December 31, 1999, the Company had $47.8 million of net operating
loss carryforwards available to offset future taxable income, as follows:

Management has determined, based on the Company's history of prior earnings
and its expectations for the future, that future taxable income will more likely
than not be sufficient to utilize fully the deferred tax assets recorded.

The Company and its subsidiaries entered into a tax sharing agreement (the
"Tax Sharing Agreement") dated January 31, 1994 with GAF and G-I Holdings under
which the Company is obligated to pay G-I Holdings an amount equal to those
Federal income taxes the Company would have incurred if the Company (on behalf
of itself and its subsidiaries) filed its own Federal income tax return. Unused
tax attributes will carry forward for use in reducing amounts payable by the
Company to G-I Holdings in future years, but cannot be carried back. If the
Company were no longer a member of the GAF consolidated tax group (the "GAF
Group"), it would be required to pay to G-I Holdings the value of any tax
attributes it would succeed to under the consolidated return regulations to the
extent such attributes reduced the amounts otherwise payable by the Company
under the Tax Sharing Agreement. Under certain circumstances, the provisions of
the Tax Sharing Agreement could result in the Company having a greater liability
thereunder than it would have had if it (and its subsidiaries) had filed its own
separate Federal income tax return. Under the Tax Sharing Agreement, the Company
and each of its subsidiaries are responsible for any taxes that would be payable
by reason of any adjustment to the tax returns of GAF or its subsidiaries for
years prior to the adoption of the Tax Sharing Agreement that relate to the
business or assets of the Company or any subsidiary of the Company. Although, as
a member of the GAF Group, the Company is severally liable for all Federal
income tax liabilities of every member of the GAF Group, including tax
liabilities not related to the business of the Company, G-I Holdings and GAF
have agreed to indemnify the Company and its subsidiaries for all tax
liabilities of the GAF Group other than tax liabilities (i) arising from the
operations of the Company and its subsidiaries and (ii) for tax years pre-dating
the Tax Sharing Agreement that relate to the business or assets of the Company
and its subsidiaries. The Tax Sharing Agreement provides for analogous
principles to be applied to any consolidated, combined or unitary state or local
income taxes. Under the Tax Sharing Agreement, GAF makes all decisions with
respect to all matters relating to taxes of the GAF Group. The provisions of the
Tax Sharing Agreement take into account both the Federal income taxes the
Company would have incurred if it filed its own separate Federal income tax
return and the fact that the

F-21

NOTE 6. INCOME TAXES--(CONTINUED)

Company is a member of the GAF Group for Federal income tax purposes. In
accordance with the Tax Sharing Agreement, effective January 31, 1994, tax
benefits generated by net operating losses and credits will reduce future tax
sharing payments to G-I Holdings.

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, GFC, held 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 GAF incurring liabilities significantly in excess of the
deferred tax liability of $131.4 million that it recorded in 1990 in connection
with this matter. GAF has advised the Company that it believes that it will
prevail in this matter, although there can be no assurance in this regard.
However, if GAF is unsuccessful in challenging its tax deficiency notice, the
ability of GAF to satisfy its tax obligation would be dependent on the cash
flows of the Company and GFC. 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. 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 GAF be unable to satisfy such liability. See
Note 3.

NOTE 7. SALE OF ACCOUNTS RECEIVABLE

In March 1993, the Company sold its trade accounts receivable
("receivables") to a trust, without recourse, pursuant to an agreement which
provided for a maximum of $75 million in cash to be made available to the
Company based on eligible receivables outstanding from time to time. In November
1996, the Company entered into new agreements, pursuant to which it sold the
receivables to a special purpose subsidiary of the Company, BMCA Receivables
Corporation, without recourse, which in turn sold them to a new trust, without
recourse. The new agreements provide for a maximum of $115 million in cash to be
made available to the Company based on eligible receivables outstanding from
time to time. This facility expires in December 2001. The excess of accounts
receivable sold over the net proceeds received is included in "Accounts
receivable, other." The effective cost to the Company varies with LIBOR and is
included in "Other income, net" and amounted to $5.1, $5.1 and $5.5 million in
1997, 1998 and 1999, respectively.

NOTE 8. INVENTORIES

At December 31, 1998 and 1999, $10.2 and $8.9 million, respectively, of

Included in the net book value of machinery and equipment at December 31,
1998 and 1999 was $12,468 and $10,508, respectively, for assets under capital
leases.

During 1999, in connection with the construction of two new manufacturing
facilities, the Company entered into two leases for certain machinery and
equipment, which leases meet the criteria of operating leases under SFAS No. 13
"Accounting for Leases." In connection therewith, at December 31, 1999,
property, plant, and equipment, net, and accrued liabilities included
$65.6 million of assets under such leases. Such amounts will be reversed when
the manufacturing facilities become fully operational, which is expected to
occur in 2000. These leases require quarterly rental payments and are for a
ten-year period expiring in December 2009.

In August 1999, the Company entered into a $31.9 million bank term loan
maturing on July 1, 2004 (the "Term Loan"). The Term Loan bears interest at a
floating rate based on the bank's base rate, the federal funds rate, or LIBOR,
at the option of the Company. Under the Term Loan, the principal amount
outstanding will convert, subject to the satisfaction of certain conditions, no
later than July 6, 2000, to senior notes with a maturity date of December 1,
2008. The senior notes will bear interest at a rate that will be set at the
time of conversion. The Company used all of the net proceeds of the Term Loan to
purchase, and subsequently cancel, the remaining $29.9 million in aggregate

F-23

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

NOTE 10. LONG-TERM DEBT--(CONTINUED)

principal amount of the Company's outstanding 11 3/4% Senior Deferred Coupon
Notes due 2004 (the "Deferred Coupon Notes"). The redemption price was 105.875%
of the principal amount outstanding, and the premium was recorded as an
extraordinary loss, net of tax, of approximately $1.3 million.

On December 3, 1998, the Company issued $155 million in aggregate principal
amount of 8% Senior Notes due 2008 (the "2008 Notes"). The Company used
substantially all of the net proceeds from such issuance to purchase, and
subsequently cancel, $147.1 million in aggregate principal amount at maturity of
the Company's Deferred Coupon Notes. In connection with this purchase, the
Company recorded an after-tax extraordinary loss of $8.8 million.

On July 17, 1998, the Company issued $150 million in aggregate principal
amount of 7 3/4% Senior Notes due 2005 (the "2005 Notes"). The Company used
substantially all of the net proceeds from such issuance to purchase, and
subsequently cancel, $132.6 million in aggregate principal amount at maturity of
the Company's Deferred Coupon Notes. In connection with this purchase, the
Company recorded an after-tax extraordinary loss of $9.3 million.

In October 1997, the Company issued $100 million in aggregate principal
amount of 8% Senior Notes due 2007 (the "2007 Notes"). In December 1996, the
Company issued $100 million in aggregate principal amount of 8 5/8% Senior Notes
due 2006 (the "2006 Notes"). Holders of the 2005 Notes, the 2007 Notes, the 2008
Notes and the 2006 Notes have the right under the indentures governing such
notes to require the Company to purchase the 2005 Notes, the 2007 Notes, the
2008 Notes and the 2006 Notes (collectively, the "Other Senior Notes") at a
price of 101% of the principal amount thereof, and the Company has the right to
redeem the Other Senior Notes at a price of 101% of the principal amount
thereof, plus, in each case, the Applicable Premium (as defined therein),
together with any accrued and unpaid interest, in the event of a Change of
Control (as defined therein).

The indentures relating to the Other Senior Notes, the Credit Agreement
(see below) and the Term Loan contain covenants that, among other things, limit
the ability of the Company and its subsidiaries to pay certain dividends or make
certain other restricted payments and restricted investments, incur liens,
engage in transactions with affiliates, and agree to certain additional
limitations on dividends and other payment restrictions affecting subsidiaries.
As of December 31, 1999, after giving effect to the most restrictive of the
aforementioned restrictions, the Company could have paid dividends and made
other restricted payments of up to $76.1 million. Additional borrowings by the
Company are subject to certain covenants contained in the indentures relating to
the Other Senior Notes, the Credit Agreement and the Term Loan.

In connection with the Deferred Coupon Notes, the Company entered into
interest rate swap agreements ("swaps") with banks, with an aggregate ending
notional principal amount of $142.0 million and a final maturity of July 1,
1999, all of which were terminated as of June 28, 1998. In 1997, the Company
terminated swaps with an aggregate ending notional principal amount of $82.0
million, resulting in gains totaling $2.1 million. In June 1998, the Company
terminated swaps with an aggregate ending notional principal amount of $60.0
million, resulting in gains of $0.7 million. The gains were deferred and were
amortized as a reduction of interest expense over the remaining original life of
the swaps. As a result of the swaps, the effective interest cost to the Company
of the portion of the Deferred Coupon Notes covered by the swaps varied at a
fixed spread over LIBOR.

In August 1999, the Company entered into a new three-year bank credit
facility (the "Credit Agreement"). The terms of the Credit Agreement provide for
a $110 million revolving credit facility, the full amount of which is available
for letters of credit, provided that total borrowings and outstanding letters of
credit may not exceed $110 million in the aggregate. As of December 31, 1999,
$27.1 million of letters of credit and no borrowings were outstanding under the
Credit Agreement. Under the terms of the Credit Agreement, the Company is
subject to certain financial covenants, including interest coverage and leverage
ratios, along with a limitation on the amount of dividends and other restricted
payments made to affiliates. Additionally, if a change of control (as defined in
the Credit Agreement) occurs, the Credit Agreement could be terminated and the
loans thereunder accelerated by the lenders party thereto, an event which could
also cause the Company's outstanding senior notes

F-24

BUILDING MATERIALS CORPORATION OF AMERICA

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

NOTE 10. LONG-TERM DEBT--(CONTINUED)

to be accelerated. As of December 31, 1999, the Company was in compliance with
all such covenants. The Credit Agreement replaced a previous bank credit
facility which provided up to $75 million in total borrowings and outstanding
letters of credit.

In December 1995, the Company consummated a $40 million sale-leaseback of
certain equipment located at its Chester, South Carolina roofing facility, in a
transaction accounted for as a capital lease, and the gain has been deferred.
The lessor was granted a security interest in certain equipment at the Chester
facility. The lease term extends to December 2005. In December 1994, the Company
consummated a $20.4 million sale-leaseback of certain equipment located at its
Baltimore, Maryland roofing facility, in a transaction accounted for as a
capital lease, and the gain has been deferred. The lessor was granted a security
interest in the land, buildings and certain equipment at the Baltimore facility.
The lease term extends to December 2004. In December 1993, the Company obtained
a loan of $7.3 million, which is secured by manufacturing equipment located at
its Dallas plant. The loan is being repaid over a seven-year period and has a
fixed interest rate. The Company has four industrial revenue bond issues
outstanding, which bear interest at short-term floating rates. Interest rates on
the foregoing obligations ranged between 3.80% and 5.20% as of December 31,
1999.

The Company believes that the fair value of its non-public indebtedness
approximates the book value of such indebtedness, because the interest rates on
substantially all such indebtedness are at floating short-term rates. With
respect to the Company's publicly traded debt securities, the Company has
obtained estimates of the fair values from an independent source believed to be
reliable. The estimated fair value of the Company's indebtedness at December 31,
1998 and 1999 are as follows:

NOTE 11. BENEFIT PLANS

Eligible, full-time employees of the Company are covered by various benefit
plans, as described below.

Defined Contribution Plan

The Company provides a defined contribution plan for eligible employees.
The Company contributes up to 7% of participants' compensation and also
contributes fixed amounts, ranging from $50 to $750 per year depending on age,
to the accounts of participants who are not covered by a Company-provided
postretirement medical benefit plan. The aggregate contributions by the Company
were $3.5, $4.2 and $4.4 million for 1997, 1998 and 1999, respectively.

U.S. Intec provides a defined contribution plan for eligible employees.
U.S. Intec may contribute a discretionary matching contribution equal to 100% of
each participant's eligible contributions each year up to a maximum of $750 for
each participant. Such contributions by U.S. Intec were $0.1, $0.1 and
$0.2 million for 1997, 1998 and 1999, respectively.

Defined Benefit Plans

The Company provides noncontributory defined benefit retirement plans for
certain hourly and salaried employees (the "Retirement Plans"). Benefits under
these plans are based on stated amounts for each year of service. In 1998, the
Company acquired LL Building Products Inc. which has pension plans for its
hourly and salaried employees. The LL Building Products Inc. plans were
curtailed in 1998. The Company's funding policy is consistent with the minimum
funding requirements of ERISA.

The Company's net periodic pension cost for the Retirement Plans included

expected long-term rate of return on assets, used in determining net periodic
pension cost, was 11% for 1998 and 1999.

The Company also provides a nonqualified defined benefit retirement plan
for certain key employees. Expense accrued for this plan was immaterial for
1997, 1998 and 1999.

Book Value Appreciation Unit Plan

A Book Value Appreciation Unit Plan was implemented effective January 1,
1996. Under the plan, employees were granted units which vest over five years.
Upon exercise, employees were entitled to receive a cash payment based on the
increase in Book Value (as defined in the plan). This plan was terminated in
1999 with all eligible employees receiving their respective vested cash
payments. Expense accrued under this plan was $0.4, $1.3 and $1.2 million for
1997, 1998 and 1999, respectively.

Postretirement Medical and Life Insurance

The Company generally does not provide postretirement medical and life
insurance benefits, although it subsidizes such benefits for certain employees
and certain retirees. Such subsidies were reduced or ended as of January 1,

NOTE 11. BENEFIT PLANS--(CONTINUED)

For purposes of calculating the accumulated postretirement benefit
obligation, the following assumptions were made. Retirees as of December 31,
1999 who were formerly salaried employees (with certain exceptions) were assumed
to receive a Company subsidy of $700 to $1,000 per year. For retirees over age
65, this subsidy may be replaced by participation in a managed care program.
With respect to retirees who were formerly hourly employees, most such retirees
are subject to a $5,000 per person lifetime maximum benefit. Subject to such
lifetime maximum, an 11% and 6% annual rate of increase in the Company's per
capita cost of providing postretirement medical benefits was assumed for 2000
for such retirees under and over age 65, respectively. To the extent that the
lifetime maximum benefits have not been reached, the foregoing rates were
assumed to decrease gradually to an ultimate rate of 7% and 6%, respectively, by
the year 2003 and remain at that level thereafter. The weighted average assumed
discount rate used in determining the accumulated postretirement benefit
obligation was 7% and 7.75% for 1998 and 1999, respectively.

The health care cost trend rate assumption has an effect on the amounts
reported. To illustrate, increasing the assumed health care cost trend rates by
one percentage point in each year would increase the accumulated postretirement
benefit obligation as of December 31, 1998 and 1999 by $90,000 and $76,000,
respectively, and the aggregate of the service and interest cost components of
the net periodic postretirement benefit cost for the years 1998 and 1999 by
$6,000 and $5,000, respectively. A decrease of one percentage point in each year
would decrease the accumulated postretirement benefit obligation as of December
31, 1998 and 1999 by $80,000 and $68,000, respectively, and the aggregate of the
service and interest cost components of the net periodic postretirement benefit
cost for the years 1998 and 1999 by $6,000 and $5,000, respectively.

NOTE 12. PREFERRED STOCK OPTION PLAN

On January 1, 1996, the Company established a plan to issue options to
certain employees to purchase shares of redeemable convertible preferred stock
("Preferred Stock") of the Company, exercisable at a price of $100 per share.
Each share of Preferred Stock is convertible, at the holder's option, into
shares of common stock of the Company at a formula price based on Book Value (as
defined in the option agreement) as of the date of grant. The options vest
rateably over five years and expire after nine years. Dividends will accrue on
the Preferred Stock from the date of issuance at the rate of 6% per annum. The
Preferred Stock is redeemable, at the Company's option, for a redemption price
equal to $100 per share plus accrued and unpaid dividends. The Preferred Stock,
and common stock issuable upon conversion of Preferred Stock into common stock,
is subject to repurchase by the Company under certain circumstances, at a price
equal to current Book Value (as defined in the option agreement). The exercise
price of the options to purchase Preferred Stock was equal to the estimated fair
value per share of the Preferred Stock at the date of grant. The options
exercised in 1999 were converted into 4,611 shares of common stock. No expense
is recorded in connection with the Preferred Stock options.

The following is a summary of transactions pertaining to the plan:

NOTE 13. BUSINESS SEGMENT INFORMATION

The Company is a leading national manufacturer of a broad line of asphalt
roofing products and accessories for the residential and commercial roofing
markets. The Company also manufactures and markets specialty building products
and accessories for the professional and do-it-yourself remodeling and
residential construction industries. The residential roofing product line
primarily consists of premium laminated shingles, strip shingles and certain
specialty shingles principally for regional markets. Sales of residential
roofing products represented approximately 65% of the Company's net sales in
1999. The Company's commercial roofing product line includes a full line of
modified bitumen products, asphalt built-up roofing, liquid applied membrane and
roofing accessories. Sales of commercial roofing products and accessories
represented approximately 27% of the Company's net sales in 1999. Sales of the
specialty building products and accessories product line represented
approximately 8% of the Company's net sales in 1999.

In 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information," which establishes standards for companies
to report information about operating segments in annual financial statements,
based on the approach that management utilizes to organize the segments within
the Company for management reporting and decision making. In accordance with the
provisions of SFAS No. 131, the Company aggregates the residential and
commercial product lines into one operating segment, since they have similar
economic characteristics and are similar in each of the following areas:
(i) the nature of the products and services are similar in that they perform the
same function--the protection and covering of residential and commercial roofs;
(ii) the nature of the production processes are similar; (iii) the type or class
of customer for their products and services are similar; (iv) the residential
and commercial products have the same distribution channels, whereby the main
customers are wholesalers or distributors; and (v) regulatory requirements are
generally the same for both the residential and commercial product lines. The
specialty building products and accessories product line did not meet
quantitative thresholds in 1999 to be considered as a reportable segment.

Net revenues included sales to The Home Depot, Inc. in 1999 and American
Builders & Contractors Supply Co., Inc. in 1998 and 1999, which accounted for
approximately 11%, and 11% and 10%, respectively, of the Company's net sales. No
other customer accounted for as much as 10% of net sales in 1998 or 1999.

NOTE 14. RELATED PARTY TRANSACTIONS

Included in the Consolidated Balance Sheets are the following receivable
(payable) balances with related parties, which arise from operating and
financing transactions between the Company and its affiliates:



DECEMBER 31,

The Company makes loans to, and borrows from, G-I Holdings and its
subsidiaries at prevailing market rates (between 5.82% and 5.96% during 1998).
The highest amount of loans made by the Company to G-I Holdings during 1998 and
1999 was $6.2 million and $0, respectively. No loans were made to the Company by
G-I Holdings and its subsidiaries during 1998 and 1999. In addition, the Company
advances funds on a non-interest bearing basis to GAF, G-I Holdings and their
subsidiaries. The net balance of such advances as of December 31, 1998 and 1999
was $0.9 and $59.1 million, respectively. During 1998 and 1999, the Company made
distributions of $0 and $60.0 million, respectively, to its parent company.

F-30

BUILDING MATERIALS CORPORATION OF AMERICA

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

NOTE 14. RELATED PARTY TRANSACTIONS--(CONTINUED)

Mineral Products: The Company and its subsidiaries purchase all of their
colored roofing granules requirements (except for the requirements of its
California and Oregon roofing plants and a portion of the requirements of its
Indiana roofing plant, which are supplied by a third party) from ISP under a
requirements contract. This contract is subject to annual renewal unless
terminated by either party to such agreement. Such purchases by the Company and
its subsidiaries totaled $51.1, $62.6 and $57.3 million for 1997, 1998 and 1999,
respectively. The amount payable to ISP at December 31, 1998 and 1999 for such
purchases was $4.9 and $2.9 million, respectively.

Management Agreements: The Company is a party to a Management Agreement
with ISP (the "Management Agreement"), which expires December 31, 2000, pursuant
to which ISP provides certain general management, administrative, legal,
telecommunications, information and facilities services to the Company
(including the use of the Company's headquarters in Wayne, New Jersey). Charges
to the Company by ISP for providing such services aggregated $4.8, $4.3 and
$5.3 million for 1997, 1998 and 1999, respectively. Such charges consist of
management fees and other reimbursable expenses attributable to, or incurred by
ISP for the benefit of, the Company. Effective January 1, 2000, the term of the
Management Agreement was extended through the end of 2000, and the management
fees payable thereunder were increased. The Company and ISP also allocate a
portion of the management fees payable by the Company under the Management
Agreement to separate lease payments for the use of BMCA's headquarters. Based
on the services provided by ISP to the Company in 1999 under the Management
Agreement, the aggregate amount payable by the Company to ISP under the
Management Agreement for 2000 is expected to be approximately $6.0 million.
Certain of the Company's executive officers receive their compensation from ISP,
with ISP being indirectly reimbursed therefore by virtue of the management fee
and other reimbursable expenses payable under the Management Agreement.

Tax Sharing Agreement: See Note 6.

NOTE 15. COMMITMENTS AND CONTINGENCIES

The discussions as to legal matters involving the Company contained in
Item 3, "Legal Proceedings--Environmental Litigation" and--"Other Litigation"
are incorporated herein by reference.

GAF, G-I Holdings, G Industries, GFC, GAFBMC, and BHC are presently
dependent upon the earnings and cash flows of their subsidiaries, principally
the Company, in order to satisfy their net obligations, including the
asbestos-related liability (discussed in Note 3), various tax and other
liabilities (net of certain insurance receivables), including tax liabilities
relating to the surfactants partnership (discussed in Note 6) and advances
payable to the Company (discussed in Note 14). GAF has advised the Company that
it expects to obtain funds to satisfy such obligations from, among other things,
dividends and loans from subsidiaries (principally the Company), as to which
there are restrictions under the indentures relating to the Other Senior Notes,
the Credit Agreement and the Term Loan, from payments pursuant to the Tax
Sharing Agreement between GAF and the Company and from proceeds from insurance
recoveries. During the twelve months ending December 31, 2000, the Company
expects to make distributions and/or advances to its parent to satisfy the
obligations discussed above. The Company does not believe that the dependence of
its parent corporations on the cash flows of their subsidiaries should have a
material adverse effect on the operations, liquidity or capital resources of the
Company. See Notes 3, 6 and 10.

The leases for certain property, plant and equipment at certain of the
Company's roofing facilities are accounted for as capital leases (see Note 10).
The Company is also a lessee under operating leases principally for warehouses,
production machinery and equipment, and transportation and computer equipment.
Rental expense on operating leases was $9.2, $11.0 and $15.5 million for 1997,
1998 and 1999, respectively. Future minimum

NOTE 16. GUARANTOR FINANCIAL INFORMATION

Effective January 1, 1999, Building Materials Corporation of America (the
"Company" or "Parent Company") transferred all of its investment assets and
intellectual property assets to Building Materials Investment Corporation
("BMIC"), a newly-formed, wholly-owned subsidiary. In connection with this
transfer, BMIC agreed to guarantee all of the Company's obligations under the
Company's then existing bank credit facility and the Other Senior Notes. The
Company also transferred all of its manufacturing assets, other than those
located in Texas, to Building Materials Manufacturing Corporation ("BMMC"),
another newly-formed, wholly-owned subsidiary. In connection with this transfer,
BMMC agreed to become a co-obligor on the 2007 Notes and to guarantee the
Company's obligations under the then existing credit facility, the Deferred
Coupon Notes and the Other Senior Notes. In addition, in August 1999, BMIC and
BMMC guaranteed the Company's obligations under the Credit Agreement and the
Term Loan. The guarantees of BMIC and BMMC are full, unconditional and joint and
several.

In addition, in connection with the above transactions, the Company and
BMMC entered into license agreements, effective January 1, 1999, for the right
to use intellectual property, including patents, trademarks, know-how, and
franchise rights owned by BMIC for a license fee stated as a percentage of net
sales. The license agreements are for a period of one year and can be terminated
with 60 days written notice. Also, effective January 1, 1999, BMMC will sell all
finished goods to the Company at a manufacturing profit.

Presented below is condensed consolidating financial information for BMIC
and BMMC, prepared on a basis which retroactively reflects the formation of such
companies, as discussed above, for all periods presented. This financial
information should be read in conjunction with the Consolidated Financial
Statements and other notes related thereto. Separate financial information for
BMIC and BMMC is not included herein because management has determined that such
information is not material to investors.
