                                    PART I

Item 1. BUSINESS

      Congoleum Corporation (the "Company") was incorporated in Delaware in
1986, but traces its history in the flooring business back to Nairn Linoleum Co.
which began in 1886. On March 11, 1993 (effective on February 28, 1993), the
business and assets of the Company and those of the Amtico Tile Division of
American Biltrite Inc. (the "Tile Division") were combined (the "Acquisition").
The Acquisition was effected through the organization of a new corporation,
Congoleum Holdings Incorporated ("Congoleum Holdings"), to which Hillside
Industries Incorporated ("Hillside Industries") contributed all of the
outstanding capital stock of Resilient Holdings Incorporated ("Resilient"), the
owner of all of the outstanding capital stock of the Company, and to which
American Biltrite Inc. ("American Biltrite") contributed the assets and certain
liabilities of the Tile Division. Upon consummation of the Acquisition,
Congoleum Holdings owned all of the outstanding capital stock of Resilient,
which, in turn, owned all of the outstanding capital stock of the Company, and
the Company owned the Tile Division. The assets and liabilities comprising the
Tile Division which were acquired by the Company in the Acquisition are held
directly by the Company. On February 8, 1995, the Company completed a public
offering of 4,650,000 shares of Class A Common Stock (the "Offering"). Upon
completion of the Offering, the Company implemented a Plan of Repurchase
pursuant to which its two-tiered holding company ownership structure was
eliminated through the merger of Congoleum Holdings with and into the Company,
with the Company as the surviving corporation.

      Congoleum produces both sheet and tile floor covering products with a wide
variety of product features, designs and colors. Sheet flooring, in its
predominant construction, is produced by applying a vinyl gel to a flexible
felt, printing a design on the gel, applying a wearlayer, heating the gel layer
sufficiently to cause it to expand into a cushioned foam and, in some products,
adding a high-gloss coating. The Company also produces through-chip inlaid
products for both residential and commercial markets. These products are
produced by applying an adhesive coat and solid vinyl colored chips to a felt
backing and laminating the sheet under pressure with a heated drum. Tile
flooring is manufactured by creating a base stock (consisting primarily of
limestone and vinyl resin) which is less flexible than the backings for sheet
flooring, and transferring or laminating to it preprinted colors and designs
followed by a wearlayer and a urethane coating in some cases. Commercial tile is
manufactured by including colored vinyl chips in the pigmented base stock. For
do-it-yourself tile, an adhesive is applied to the back of the tile. The
differences between products within each of the two product lines consist
primarily of content and thickness of wearlayers and coatings, the use of
chemical embossing to impart a texture, the complexity of designs and the number
of colors.

Raw Materials

      The principal raw materials used in the manufacture of sheet and tile
flooring are vinyl resins, plasticizers, latex, limestone, stabilizers,
cellulose paper fibers, urethane and transfer print paper. Most of these raw
materials are purchased from multiple sources. The Company has had no difficulty
in obtaining its requirements for these materials, although significant price
increases in certain materials have been experienced at times.


                                       3
<PAGE>

      The Company believes that alternative suppliers are available for
substantially all of its raw material requirements. However, the Company does
not have readily available alternative sources of supply for specific designs of
transfer print paper, which are produced utilizing print cylinders engraved to
the Company's specifications. Although no loss of this source of supply is
anticipated, replacement could take a considerable period of time and interrupt
production of certain products. The Company maintains a raw material inventory
and has an ongoing program to develop new sources which will provide continuity
of supply for its raw material requirements.

Patents and Trademarks

      The Company believes that the Congoleum brand name, as well as the other
trademarks it holds, are important to maintaining competitive position. In 1993,
the Company sold the rights to the Amtico trademark in the United States and
began selling tile under the Congoleum brand name.

      The Company also believes that patents and know-how play an important role
in maintaining competitive position. In particular, the Company utilizes a
proprietary transfer printing process for certain tile products that it believes
produces visual effects that only one other competitor is presently able to
duplicate.

Distribution

      The Company currently sells its products through approximately 30
distributors providing approximately 90 distribution points in the United States
and Canada, as well as directly to a limited number of mass market retailers.
The sales pattern is seasonal, with peaks in retail sales typically occurring
during March/April/May and September/October. Orders are generally shipped as
soon as a truckload quantity has been accumulated, and backorders can be
canceled without penalty. At December 31, 1998, the backlog of unshipped orders
was $13.9 million, compared to $7.5 million at December 31, 1997.

      The Company considers its distribution network very important to
maintaining competitive position. While most of its distributors have marketed
the Company's products for many years, replacements are necessary periodically
to maintain the strength of the distribution network. Although the Company has
more than one distributor in some of its distribution territories and actively
manages its credit exposure to its customers, the loss of a major customer could
have a materially adverse impact on the Company's sales, at least until a
suitable replacement was in place. For the year ended December 31, 1998, two
customers each accounted for over 10% of the Company's sales. These customers
were its distributor to the manufactured housing market, LaSalle-Bristol, and
its distributor in the Western U.S., LD Brinkman & Co. Together, they accounted
for 47% of the Company's net sales in 1998.

Working Capital

      The Company produces goods for inventory and sells on credit to customers.
Generally, the Company's distributors carry inventory as needed to meet local or
rapid delivery requirements. Credit sales are typically subject to a discount if
paid within terms.


                                       4

Product Warranties

      The Company offers a limited warranty on all of its products against
manufacturing defects. In addition, as a part of efforts to differentiate mid
and high-end products through color, design and other attributes, the Company
offers enhanced warranties with respect to wear, moisture discoloration and
other performance characteristics which increase with the price points of such
products.

Competition

      The market for the Company's products is highly competitive. Resilient
sheet and tile compete for both residential and commercial customers primarily
with carpeting, hardwood, melamine laminate and ceramic tile. In residential
applications, both tile and sheet products are used primarily in kitchens,
bathrooms, laundry rooms and foyers and, to a lesser extent, in playrooms and
basements. Ceramic tile is used primarily in kitchens, bathrooms and foyers.
Carpeting is used primarily in bedrooms, family rooms and living rooms. Hardwood
flooring and melamine laminate are used primarily in family rooms, foyers and
kitchens. Commercial grade resilient flooring faces substantial competition from
carpeting, ceramic tile, rubber tile, hardwood flooring and stone in commercial
applications. The Company believes, based upon its market research, that
purchase decisions are influenced primarily by fashion elements such as design,
color and style, durability, ease of maintenance, price and ease of
installation. Both tile and sheet resilient flooring are easy to replace for
repair and redecoration and, in the Company's view, have advantages over other
floor covering products in terms of both price and ease of installation and
maintenance.

      The Company encounters competition from domestic and, to a much lesser
extent foreign manufacturers. Certain of the Company's competitors, including
Armstrong in the resilient category, have substantially greater financial and
other resources than the Company.

Research and Development

      The Company's research and development efforts concentrate on new product
development, trying to increase product durability and expanding technical
expertise in the manufacturing process. Expenditures for research and
development for the year ended December 31, 1998 were $3.8 million, compared to
$3.7 million and $4.6 million for the years ended December 31, 1997 and 1996,
respectively.

Environmental Regulation

      Due to the nature of the Company's business and certain of the substances
which are or have been used, produced or discharged by the Company, the
Company's operations are subject to extensive federal, state and local laws and
regulations relating to the generation, storage, disposal, handling, emission,
transportation and discharge into the environment of hazardous substances. The
Company, pursuant to administrative consent orders signed in 1986 and in
connection with a prior restructuring, is in the process of implementing cleanup
measures at its Trenton sheet facility under New Jersey's Environmental Clean-up
Responsibility Act, as amended by the New Jersey 


                                       5
<PAGE>

Industrial Site Recovery Act. The Company does not anticipate that the
additional costs of these measures will be material. In connection with the
Acquisition of the Tile Division, American Biltrite signed a similar consent
order with respect to the Trenton tile facility, and the Company agreed to be
financially responsible for any cleanup measures required. In 1998, the Company
incurred capital expenditures of approximately $.3 million for environmental
compliance and control facilities.

      The Company has historically expended substantial amounts for compliance
with existing environmental laws and regulations, including those matters
described above. The Company will continue to be required to expend amounts in
the future, due to the nature of historic activities at its facilities, to
comply with existing environmental laws, and those amounts may be substantial
but should not, in the Company's judgment, have a material adverse effect on the
financial position of the Company. Because environmental requirements have grown
increasingly strict, however, the Company is unable to determine the ultimate
cost of compliance with environmental laws and enforcement policies.

Employees

      At December 31, 1998, the Company employed a total of 1,250 personnel
compared to 1,234 employees at December 31, 1997.

      The Company has entered into collective bargaining agreements with hourly
employees at three of its plants and with the drivers of the trucks that provide
interplant transportation. These agreements cover approximately 702 of the
Company's employees. The Trenton tile plant has a five-year collective
bargaining agreement which expires in May 2003. The Marcus Hook plant has a
five-year collective bargaining agreement which expires in November 2003. The
Trenton sheet plant has a five-year collective bargaining agreement which
expires in February 2001. The Finksburg plant has no union affiliation. In the
past five years, there have been no significant strikes by employees at the
Company and the Company believes that its employee relations are satisfactory.

Item 2. PROPERTIES

      The Company owns four manufacturing facilities located in Maryland,
Pennsylvania and New Jersey and leases corporate and marketing offices in
Mercerville, New Jersey, where it has a lease expiring in 2000, as well as
storage space in Trenton, New Jersey, which are described below:

    Location                 Owned/Leased  Usage                Square Feet
    --------                 ------------  -----                -----------

    Finksburg, MD            Owned         Felt                   107,000
    Marcus Hook, PA          Owned         Sheet Flooring       1,000,000
    Trenton, NJ              Owned         Sheet Flooring       1,050,000
    Trenton, NJ              Owned         Tile Flooring          282,000
    Trenton, NJ              Leased        Warehousing             20,000
    Mercerville, NJ          Leased        Corporate Offices       33,597

      The Finksburg facility consists primarily of a 16-foot wide felt
production line.

      The Marcus Hook facility is capable of manufacturing rotogravure printed
sheet flooring in widths of up to 16 feet. Major production lines at this
facility include a 12-foot wide oven, two 16-foot wide ovens, a 12-foot wide
printing press and a 16-foot wide printing press.

      The Trenton sheet facility is capable of manufacturing rotogravure printed
and through-chip inlaid sheet products in widths up to 6 feet. Major production
lines, all six-foot wide, include an oven, a rotary laminating line and a press.
The examination, packing and warehousing of all sheet products (except products
for the manufactured housing segment) occur at the Trenton plant distribution
center.

      The Trenton tile facility consists of three major production lines, a
four-foot wide commercial tile line, a two-foot wide residential tile line and a
one-foot wide residential tile line.

      Productive capacity and extent of utilization of the Company's facilities
are dependent on a number of factors, including the size, construction, and
quantity of product being manufactured, some of which also dictate which
production line(s) must be utilized to make a given product. The Company's major
production lines were operated an average of 76% of the hours available on a
five-day, three-shift basis in 1998, with the corresponding figure for
individual production lines ranging from 13% to 120%.

      Although many of the Company's manufacturing facilities have been
substantially depreciated, the Company has generally maintained and improved the
productive capacity of these facilities over time through a program of regular
capital expenditures. The Company considers its manufacturing facilities to be
adequate for its present and anticipated near-term production needs.

Item 3. LEGAL PROCEEDINGS

      As of December 31, 1998 the Company was named as a defendant, together in
most cases with numerous other defendants, in approximately 657 pending lawsuits
(including workers' compensation cases) involving approximately 1,984
individuals alleging personal injury from exposure to asbestos or
asbestos-containing products. The plaintiffs in these cases seek compensation
for injuries sustained in the course of their employment by third parties (or,
in the workers' compensation cases, by the Company) as a result of exposure to
asbestos in products manufactured by the Company or the Tile Division of
American Biltrite. The Company discontinued the manufacture of
asbestos-containing sheet vinyl flooring products in 1983 and the Tile Division
ceased manufacturing asbestos-containing vinyl tile flooring products in 1984.
In general, asbestos-containing products have not been found to pose a health
risk unless significant amounts of free asbestos fibers become airborne. All of
the asbestos in the asbestos-containing products previously sold by the Company
and the Tile Division was fully bonded or encapsulated during the manufacturing
process. During 1998 approximately 200 personal injury cases involving the
Company were either settled or dismissed and approximately 203 new cases were
commenced against the Company. The total indemnity costs incurred during 1998 to
settle personal injury claims involving the Company (other than the cost of the
partial settlement in the personal injury case described below) was
approximately $2.2 million. All of these costs were paid by the Company's
insurance carriers. The average indemnity cost per resolved personal injury
claim was $11 thousand in 1998. Costs per claim vary depending on a number of
factors, including the number of plaintiffs, the nature of their alleged
exposure and the forum in which the claim is brought. In 1997 a judgment was
entered by the Superior Court of California in Los Angeles following a jury
trial holding the Company and another defendant jointly and severally liable for
$3.3 million in damages, subject to any applicable setoffs for previous
settlements and proportionate liability under California law. The jury found
that the Company was only liable for 25% of the non-economic damages sustained
by the plaintiff. However, as a result of post-verdict motions the court ruled
that California Proposition 51 establishing proportionate liability for
non-economic damages did not apply. The Company has appealed this decision to
the Court of Appeals of the State of California. The Company's insurance carrier
has paid the Company's defense costs in this matter and has indicated that it
would be responsible for paying the ultimate judgment in this case, subject to
the insurance carrier's denial of liability with respect to a partial settlement
of certain related claims effected by the Company which the company is
contesting. Although there can be no assurance, the Company believes, based upon
the nature of the asbestos-containing products formerly manufactured by the
Company and the Tile Division and its experience with cases to date, that any
potential liabilities it may have with respect to these personal injury cases
will not have a material adverse effect on the results of operations or
financial condition of the Company.

      Together with a large number (in most cases, hundreds) of other companies,
the Company is named as a "Potentially Responsible Party" ("PRP") in pending
proceedings under the federal Comprehensive Environmental Response, Compensation
and Liability Act ("CERCLA") and similar state laws. In two instances, although
not named as a PRP, the Company has received a request for information. These
pending proceedings currently relate to seven disposal sites in New Jersey,
Pennsylvania, Maryland, Connecticut and Delaware in which recovery from
generators of hazardous substances is sought for the cost of cleaning up the
contaminated waste sites. The Company's ultimate liability, if any, in
connection with these sites will depend on many factors, including the 


                                       10
<PAGE>

volume of material contributed to the site, the number of other PRPs and their
financial viability, the remediation methods and technology to be used and the
extent to which costs may be recoverable from insurance. However, under CERCLA
and certain other laws, as a PRP the Company could be held jointly and severally
liable for all remediation costs associated with a site.

      The most significant disposal site environmental matter in which the
Company has been named as a PRP relates to a recycling facility in Elkton,
Maryland. Two removal actions are substantially complete as of December 31,
1998, however, the groundwater remediation phase has not begun and the remedial
investigation/feasibility study related to the groundwater remediation has not
been approved. The PRP group for this site has estimated that the future costs
of groundwater remediation would be approximately $26 million of which, based on
waste allocations among members of the PRP group, the Company's share was
estimated to be approximately 5.5%. At December 31, 1998, the Company believes
its probable liability with respect to this site, based upon present facts and
circumstances, will be approximately $.5 million ($2 million estimated liability
net of anticipated insurance recoveries of $1.5 million). Although there can be
no assurance, the Company does not believe, based upon present facts and
circumstances, that its probable liability with respect to any of the other
pending disposal site environmental remediation matters to which it is a party
will be material to the results of operations or financial condition of the
Company.

      The Company is also a party to a pending proceeding relating to the
investigation and potential remediation of soil and groundwater contamination at
its manufacturing facility located at 1945 East State Street in Trenton, New
Jersey. The investigation of the nature and extent of any contamination at this
site has not been completed and the Company is therefore unable to estimate the
amount, if any, of its probable liability with respect to the potential
remediation of this site.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      The Company is exposed to changes in prevailing market interest rates
affecting the return on its investments but does not consider this interest rate
market risk exposure to be material to its financial condition or results of
operations. The Company invests primarily in highly liquid debt instruments with
strong credit ratings and short-term (less than one year) maturities. The
carrying amount of these investments approximates fair value due to the
short-term maturities. Substantially all of the Company's outstanding long-term
debt as of December 31, 1998 consisted of indebtedness with a fixed rate of
interest which is not subject to change based upon changes in prevailing market
interest rates. Under its current policies, the Company does not use derivative
financial instruments, derivative commodity instruments or other financial
instruments to manage its exposure to changes in interest rates, foreign
currency exchange rates, commodity prices or equity prices.
