ITEM 1.  BUSINESS

General
- -------

     Radnor Holdings Corporation (the "Company"), a Delaware corporation formed
in November 1991, is a leading worldwide manufacturer and distributor of
chemical and packaging products for the foodservice, insulation and packaging
industries. The Company, through its WinCup Holdings, Inc. ("WinCup")
subsidiary, is the second largest producer in the United States of foam cup and
container products for the foodservice industry. Through its Radnor Chemical
Corporation subsidiary, the Company is the fifth largest producer worldwide of
expandable polystyrene ("EPS"). The Company has 22 manufacturing facilities
located throughout the United States, Canada and Europe.

     On October 15, 1997, the Company, through its Radnor Chemical Corporation
subsidiary, acquired substantially all of the assets and assumed certain
liabilities of the polystyrene production operations of Neste Oy ("StyroChem
Europe") for $52.3 million. Proceeds from the sale of $60.0 million of the
Company's 10% Series B Senior Notes due 2003 (the "Series B Notes"), issued
pursuant to exemptions under the Securities Act of 1933, as amended, were
utilized to pay the purchase price.

     On December 5, 1996, the Company acquired Radnor Chemical Corporation and
its subsidiaries ("StyroChem"), for $23.5 million of cash plus consulting
payments, a non-compete agreement and $0.9 million of assumed indebtedness.
Effective January 1996, the Company acquired the U.S. foam cup and container
operations of Fort James Corporation, formerly James River Paper Company, Inc.

     The Company, through WinCup, has been manufacturing foam cups and
containers for more than 30 years. The WinCup foam cup and container business
was established in 1961 and began purchasing EPS from StyroChem when that
company began operations in 1976. StyroChem Europe is a leading EPS producer in
Northern Europe and has produced EPS since 1972.

Industry Overview
- -----------------

     An independent industry survey estimated that sales of disposable
foodservice products in the U.S. were in excess of $7.0 billion in 1994, with
sales of disposable cups and containers estimated to have been more than $2.0
billion. The foam segment of the disposable cup and container market, which the
Company believes had sales of approximately $600 million in 1997, is highly
concentrated, with the Company and its primary competitor accounting for more
than 80% of the market segment.

     The EPS industry is generally comprised of three grades of material: block
grade for rigid board insulation and molded parts, shape grade for a broad range
of packaging and specialty applications and T-grade for foodservice containers
and lost foam casting. The North American market for EPS products is estimated
at approximately 940 million pounds annually, including insulation, packaging
and foodservice grades. The European market is estimated at approximately 1.5
billion pounds annually consisting primarily of shape grades. Worldwide, there
are in excess of 20 manufacturers with the top five accounting for approximately
60 percent of the market.

Products
- --------

     The Company manufactures a broad range of foam cups, bowls and containers,
foam packaging products and thermoformed plastic lids. The use of foam provides
an insulating feature to the Company's products, allowing them to be used for
both hot and cold beverages and food products while enhancing comfort for the
end user. Foam cups are manufactured in varying sizes for both hot and cold
beverages and are sold under the Dixie(R), COMpac(TM), Profit Pals(R),
STYROcup(R), Handi-Kup HK(R), and Simplicity(R) brand names. Foam bowls and
other containers are made in varying sizes for both hot and cold food products
and are sold under the STYROcontainers(R) brand name. The Company also
manufactures thermoformed leak-resistant plastic lids for its cups, bowls and
containers.

                                       1
<PAGE>
 
     The Company, through StyroChem, manufactures EPS for its internal
consumption in addition to selling directly to third party manufacturers of foam
containers, insulation products and packaging products. Prior to its acquisition
by the Company, StyroChem had been a long-term supplier of EPS to the Company.

     StyroChem Europe manufactures EPS, general-purpose polystyrene and
high-impact polystyrene ("HIPS"), and also converts a significant portion of its
EPS production into a variety of standard and specialized insulation products.
StyroChem Europe's EPS is made primarily for the insulation and packaging
industries and includes a range of bead sizes and densities for conversion by
customers into light and heavy insulation boards as well as various shape
products, such as insulated fish packaging boxes. StyroChem Europe's foam
insulation operations directly convert internally produced EPS into a full range
of building insulation panels as well as specialized foam insulation products.

Sales, Marketing and Customers
- ------------------------------

     The Company sells its disposable foam packaging products through a
64-person sales organization and through an extensive network of more than 50
independent sales representatives. Sales and marketing efforts are directed by
the Company's Senior Vice President of Sales and Marketing and are supported by
12 senior sales managers with an average of more than 14 years experience in the
foodservice industry. The Company believes its experienced sales team and
long-term representative relationships enhance the Company's ability to provide
high levels of customer service and specialized marketing programs, including
custom-designed foam products. In addition, the Company sells EPS through a
dedicated sales force to manufacturers of foam packaging and insulation
products.

     StyroChem Europe markets its EPS and other polystyrene products throughout
Europe through a combination of its own sales force, sales agency arrangements
with sales offices and personnel of affiliates of Neste Oy and manufacturers'
representatives. In support of these sales and marketing efforts, StyroChem
Europe employs people who are knowledgeable of chemical engineering and
manufacturing processes in order to provide technical assistance to its
customers. StyroChem Europe maintains its own direct sales force for its foam
insulation products. A portion of this foam insulation product sales force is
decentralized, allowing StyroChem Europe to separately market specialized
products in addition to its standard product offerings.

     The Company supplies products to a number of large national companies and
foodservice distributors. No customer represented more than 8.1% of the
Company's net sales for 1997. In addition, the five largest accounts represented
approximately 27.9% of the Company's net sales for 1997. Although the Company
has not lost sales from its key customers in 1995, 1996, 1997 or 1998 to date,
if any of such customers substantially reduces its level of purchases from the
Company, the Company's profitability may be adversely affected. Moreover,
continued consolidation among distributors in the foodservice industry could
result in an increasingly concentrated customer base or the loss of certain
customers.

Manufacturing
- -------------

     The Company's foam products are made with custom-designed foam cup molding
machines, lid production machines and foam cup and container printing machines.
The Company operates ten foam plants located throughout the U.S. and four plants
located in the U.S. and Canada that manufacture EPS from styrene monomer.
StyroChem Europe operates two plants located in Finland that manufacture EPS,
general purpose polystyrene and HIPS from styrene monomer and six plants located
in Finland, Sweden and Denmark that manufacture foam insulation panels from EPS.

                                       2
<PAGE>
 
Raw Materials
- -------------

     The Company's foam products are manufactured from EPS, which is produced
from styrene monomer. Styrene monomer is a commodity petrochemical that is
readily available in bulk quantities from numerous large, vertically integrated
chemical companies. Historically, styrene monomer prices have fluctuated as a
result of changes in petrochemical prices and the capacity, supply and demand
for styrene monomer, although in recent years, such prices have been relatively
stable. Styrene monomer prices during 1996 ranged from $.27 to $.30 per pound.
During 1997 and 1998, styrene monomer prices have ranged from $.28 to $.30 per
pound.

     The StyroChem and StyroChem Europe acquisitions have not insulated the
Company from price fluctuations for styrene monomer, although they mitigate the
impact of such fluctuations by increasing the Company's flexibility to purchase
styrene monomer. Radnor Chemical Corporation, through its subsidiaries,
purchases styrene monomer from various suppliers.

     The raw materials used by the Company for the manufacture of thermoformed
lids are primarily plastic resins such as HIPS. Most of the plastic resins used
by the Company, including HIPS, are available from a variety of sources.

Risks Attendant to Foreign Operations
- -------------------------------------

     The Company conducts its businesses in numerous foreign countries and as a
result is subject to risks of fluctuations in the exchange rates of various
foreign currencies and other political and economic risks associated with
international business. The Company's foreign entities report their assets,
liabilities and results of operations in the currency in which the entity
primarily conducts its businesses. The foreign currencies are ultimately
translated into U.S. dollars for financial reporting purposes.

     See Note 11 to the Company's financial statements included herein for
information with respect to the geographic composition of the Company's
operations and financial position as of and for the year ended December 26,
1997.

Proprietary Technology and Trademarks
- -------------------------------------

     The Company has developed a broad array of proprietary technology that is
utilized in various stages of its manufacturing operations. The Company relies
primarily upon confidentiality agreements and restricted plant access to protect
its proprietary technology. The Company does own or hold license rights with
respect to numerous patents relating to its lid design in manufacturing,
embossed cup design and continuous formed foam cup manufacturing processes.
However, the Company does not consider these patents material to its operations.

     The Company holds approximately 30 registered trademarks and StyroChem
Europe holds approximately 15 trademarks. The Company does not consider these
trademarks material to its operations.

Competition
- -----------

     The Company competes in the highly competitive foodservice industry. The
foam segment of the disposable cup and container market is highly concentrated
and, within this segment, the Company competes principally with Dart Container
Corp., which has significantly greater financial resources than the Company and
controls the largest share of this market segment. The Company does not believe
that companies operating in related markets are likely to enter the foam segment
due to the significant investment that would be required.

     The Company believes that competition within the foam segment of the market
is based primarily on customer service, product quality and the price at which
products are offered. The Company believes that its market position is
attributable to its high level of customer service and product quality,
strategically located manufacturing facilities, proprietary technology and
experienced management team. The Company also competes with the paper 

                                       3
<PAGE>
 
segment, which is more fragmented than the foam segment. The Company believes
that competition between foam and paper is based on product appearance, quality
and price.

     The U.S. EPS industry is highly concentrated. Management believes that each
of Nova Chemicals, Inc., Huntsman Chemical Corp. and BASF Corporation, which are
larger and have greater financial resources than the Company, controls a
significant share of the market for supplying EPS to manufacturers of insulation
and packaging products. The Company believes that competition within this
industry is primarily based on price, although customer service and support can
be significant competitive factors, particularly among the smaller manufacturers
of foam insulation and packaging products.

     StyroChem Europe competes within the highly competitive European EPS
industry. Several companies, including BASF Corporation, Shell Oil Company,
Enichem S.P.A. and Huntsman Chemical Corp., are larger and have more substantial
financial resources than the Company. Management believes that competition is
based primarily on price, although technical support and consistently high
quality beads are important factors to many of StyroChem Europe's customers. The
Company expects that a significant percentage of StyroChem Europe's EPS
production will continue to be used internally for its foam insulation product
operations. These foam insulation product operations are located in Finland,
Sweden and Denmark, and compete primarily against other insulation manufacturers
located in these countries. Foam insulation products generally compete with
insulation products made from other materials such as mineral wool and glass
wool.

Employees
- ---------

      As of December 26, 1997, the Company had approximately 1,800 full-time
employees. Except for StyroChem Europe employees, the Company's employees are
not represented by any union. In Finland, over 90% of StyroChem Europe's
employees are represented by one of five unions and StyroChem Europe is subject
to three collective bargaining agreements. In Sweden, over 90% of StyroChem
Europe's employees are represented by one of four unions and StyroChem Europe is
subject to two collective bargaining agreements. In Denmark, StyroChem Europe's
employees are not represented by any union, nor is StyroChem Europe subject to
any collective bargaining agreement. However, all contracts for white collar
employees in Denmark must include provisions that are at least as favorable as
those provided in the Danish Employees Act. In addition, contracts for blue
collar employees in Denmark must fulfill the requirements of applicable European
Union directives regarding employment. The European Union directives are also
applicable to StyroChem Europe in Finland and Sweden; however, the terms of the
collective bargaining agreements will control employment relationships in these
countries to the extent that these agreements address relevant issues in a more
detailed manner and include benefits exceeding the minimum standards established
by the directives. The Company has never experienced a labor strike or other
labor-related work stoppage and considers its relations with its employees to be
good.

     The Company is dependent on the management experience and continued
services of the Company's executive officers, including Michael T. Kennedy. The
loss of the services of these officers could have a material adverse effect on
the Company's business. The Company is also dependent on the management
experience of the key StyroChem Europe employees who have joined the Company as
part of the StyroChem Europe acquisition. In addition, the Company's continued
growth depends on its ability to attract and retain experienced key employees.

Environmental Matters
- ---------------------

      The Company's facilities are used for manufacturing or warehousing of foam
container products or the EPS from which such products are manufactured. Many of
these facilities are subject to federal, state, foreign and local laws and
regulations relating to, among other things, emissions to air, discharges to
water and the generation, handling, storage, transportation and disposal of
hazardous and non-hazardous materials and wastes.

      Certain of the Company's manufacturing facilities generate air emissions,
including volatile organic compounds and particulate matter, that are regulated
and require permits and/or emissions control equipment. While the Company
believes that the majority of the air emissions from its facilities are properly
permitted and controlled, certain of the Company's facilities have been cited
for instances of noncompliance, although no material 

                                       4
<PAGE>
 
citations were issued within the periods covered by the financial statements
included in this Annual Report and all of these citations have been resolved
without a material adverse effect on the Company's financial condition or
results of operations. Certain of the Company's facilities also have failed to
report certain emissions as required, and it is possible that certain of the
Company's facilities lack proper air emission permits, that these permits do not
address all regulated emissions and/or that certain of the facilities are not in
full compliance with all permit conditions. Certain of the Company's Finnish and
Scandinavian facilities could be required in the future to reduce emissions of
pentane and styrene. The requirement to reduce such air emissions is subject to
negotiation with Finnish and Scandinavian regulatory authorities and could
require significant capital expenditures. The Company believes, however, that
the costs of achieving and maintaining compliance with laws and regulations
regarding air emissions are not reasonably likely to have a material adverse
effect on the Company's financial condition or results of operations, based on
its prior experience in addressing compliance matters that raised potentially
similar issues for other facilities and on the existence of an environmental
escrow account established in connection with the acquisition of StyroChem.
Furthermore, the Company has no knowledge of any claims regarding air emissions
that could be expected to have a material adverse effect on the Company's
financial condition or results of operations. However, it is possible that the
Company could incur significant fines, penalties or capital costs associated
with any confirmed noncompliance. There can be no assurance that future
environmental laws or regulations, or permit requirements under the Title V of
the Clean Air Act, will not require substantial expenditures by the Company or
significant modifications of the Company's operations.

     Certain of the Company's manufacturing facilities generate wastewater that
is regulated and requires permits for discharge. While the Company believes that
the majority of the wastewater discharges from its facilities are properly
permitted, certain of the Company's facilities have been cited for instances of
past noncompliance, although the only material citation issued within the
periods covered by the financial statements included in this Annual Report was
in 1995 for alleged noncompliance by the Fort Worth, Texas facility with a
municipal wastewater discharge ordinance. All of these citations, including the
Fort Worth citation, have been resolved without a material adverse effect on the
Company's financial condition or results of operations. Moreover, one of the
Company's facilities has failed to report wastewater pretreatment system upset
conditions as required, and it is possible that certain of the Company's
facilities currently lack proper wastewater discharge permits and/or are not in
full compliance with all permit conditions. The Company has no knowledge of any
claims regarding wastewater discharge that could be expected to have a material
adverse effect on the Company's financial condition or results of operations.
The Company believes that the costs of achieving and maintaining compliance with
laws and regulations regarding wastewater discharges is not reasonably likely to
have a material adverse effect on the Company's financial condition or results
of operations, based both on the Company's prior experience in obtaining similar
permits or addressing compliance matters that raised potentially similar issues
for other facilities and on preliminary estimates of the cost of addressing such
potential permit issues, which would be within the scope of, and are preliminary
estimated to be significantly less than, the StyroChem environmental escrow.
However, it is possible that the Company could become subject to significant
fines, penalties or capital costs associated with any confirmed noncompliance.
Furthermore, there can be no assurance that future environmental laws or
regulations will not require substantial expenditures by the Company or
significant modifications of the Company's operations.

     The Company generates and handles certain hazardous substances, including
petroleum products, and wastes in connection with its manufacturing processes.
The handling and disposal of these substances and wastes is subject to federal,
state and local regulations, and site contamination originating from the release
or disposal of such substances or wastes can lead to significant liabilities. It
is possible that certain of the Company's current or former facilities are or
were not in full compliance with applicable laws regarding the handling and
disposal of these substances and wastes. The soil and shallow groundwater at the
Company's domestic EPS facilities are known to contain elevated levels of
various contaminants. However, the Company does not believe, based on the
results of soil and groundwater testing, that material remediation efforts with
respect to these conditions will be required. Although the Company believes that
the elevated levels of various contaminants in the soil and shallow groundwater
at the Company's domestic EPS facilities and any confirmed noncompliance with
applicable laws regarding the handling and disposal of certain hazardous
substances have not had, and are not reasonably likely to have, either
individually or in the aggregate, a material adverse effect on the Company's
financial condition or results of operations, and the Company has no knowledge
of claims that could be expected to have a material adverse effect on its
financial condition or results of operations, there can be no assurance that the
Company will 

                                       5
<PAGE>
 
not incur significant costs, fines or penalties in connection with
historical on- or off-site handling or disposal of such substances and wastes or
cleanup costs for site contamination.

     The Company owns and operates underground storage tanks ("USTs") at three
of its facilities for the storage of liquid pentane. Leak detection or
containment systems are in place at all three facilities. One of the tanks,
located at the Fort Worth, Texas facility, was pressure tested in 1996 and no
leaks were detected. USTs are generally subject to federal, state, local and
foreign laws and regulations that require testing and upgrading of USTs and
remediation of polluted soils and groundwater resulting from leaking USTs. In
addition, if leakage from the Company's USTs migrates onto the property of
others, the Company may be subject to civil liability to third parties for
remediation costs or other damages. Based on historical experience, the Company
believes that its liabilities associated with UST testing, upgrades and
remediation are unlikely to have a material adverse effect on its financial
condition or results of operations.

     Certain of the Company's current and former facilities are located in
industrial areas and have been in operation for many years. As a consequence, it
is possible that historical or neighboring activities have affected properties
currently or formerly owned by the Company and that, as a result, additional
environmental issues may arise in the future, the precise nature of which the
Company cannot now predict.

ITEM 3.    LEGAL PROCEEDINGS

     On November 25, 1996, Jackson National Life Insurance Company ("Jackson")
and Benchmark Holdings, Inc. ("Holdings") filed suit in the Chancery Division of
the Circuit Court of Cook County, Illinois against Michael T. Kennedy, the
Company, WinCup, WinCup Holdings L.P., James River Paper Company, Inc. ("James
River") and James River Corporation of Virginia. The suit related to the
November 1995 sale to James River by Holdings of substantially all of Holdings'
assets, consisting of its cutlery and straws operations, and by WinCup of its
plastic cup operations. See Note 1 to the Company's Consolidated Financial
Statements included herein. Holdings had issued to Jackson certain shares of
nonvoting preferred stock in connection with the May 1991 acquisition of the
cutlery and straws operations, in which Jackson previously held an unsecured
subordinated debt position.

     On February 27, 1998, the court dismissed the suit on the basis of forum
non conveniens. The Company does not know whether Jackson and Holdings will
appeal the court's decision or file an action in a court in another
jurisdiction.

     The Company is also involved in a number of legal proceedings arising in
the ordinary course of business, none of which is expected to have a material
adverse effect on the Company's financial condition or results of operations.

ITEM 4.    SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

ITEM 5.    MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCK MATTERS

Market Information
- ------------------

      There currently exists no established public trading market for the
Company's Voting Common Stock, $.10 par value, Nonvoting Common Stock, $.10 par
value, or Class B Nonvoting Common Stock, $.01 par value. There have been no
sales of shares of any class of the Company's Common Stock by the holders
thereof since the Company's inception.

Holders
- -------

      As of March 20, 1998, there were 3 holders of record of the Company's
Voting Common Stock, 12 holders of record of the Company's Nonvoting Common
Stock and 3 holders of record of the Company's Class B Nonvoting Common Stock.

Dividends
- ---------

      In March 1997, the Company declared and paid a dividend of $480.38 per
share of the Company's Voting Common Stock, Nonvoting Common Stock and Class B
Nonvoting Common Stock. As with any company, the declaration and payment of
dividends are subject to the discretion of the Company's Board of Directors and
will depend on various factors, including the restriction of dividends to 50% of
net income contained in the Company's credit agreements and the indentures
pursuant to which the Company issued its 10% Senior Notes Due 2003 on December
5, 1996 (the "Series A Notes") and its Series B Notes.

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
           RESULTS OF OPERATION

General
- -------

     The Company is a leading worldwide manufacturer and distributor of chemical
and packaging products for the foodservice, insulation and packaging industries.
The Company, through WinCup, is the second largest producer in the United States
of foam cup and container products for the foodservice industry. Through its
Radnor Chemical Corporation subsidiary, the Company is the fifth largest
producer worldwide of EPS. The Company has 22 manufacturing facilities located
throughout the United States, Canada and Europe.

     WinCup manufactures foam cups for hot and cold drinks, foam bowls and
containers and thermoformed lids and sells its products to national,
institutional and retail customers located throughout the U.S., in Mexico and in
other countries. WinCup, through its predecessors, has been manufacturing foam
cups and containers since 1961.

     The Company, through StyroChem, manufactures EPS for its internal
consumption, in addition to selling directly to third party manufacturers of
foam containers, insulation products and packaging products. Prior to its
acquisition by the Company, StyroChem had been a long-term supplier of EPS to
the Company. EPS is categorized by grade, with the highest grade, or cup-grade,
used to manufacture foam cups and containers. Block-grade and shape-grade are
sold to manufacturers of insulation and packaging products, respectively.

     StyroChem Europe manufactures EPS, general-purpose polystyrene and HIPS,
and also converts a significant portion of its EPS production into a variety of
standard and specialized insulation products. StyroChem Europe's EPS is made
primarily for the insulation and packaging industries and includes a range of
bead sizes and densities for conversion by customers into light and heavy
insulation boards as well as various shape products, such as insulated fish
packaging boxes. StyroChem Europe works closely with its customers to
incorporate special product features into its EPS such as fire retardancy,
specialty coatings and higher thermal insulation qualities. StyroChem Europe's
foam insulation operations directly convert internally produced EPS into a full
range of building insulation panels as well as specialized foam insulation
products, such as combined metal and foam sandwich building panels, ship
insulation panels and cold room storage modules. These specialized products are
modified to conform to different building and construction requirements in
different countries.

      Net sales
      ---------

      Net sales represent the gross sales of the Company's products less cash
discounts and allowances, which historically have averaged approximately 2% of
net sales. Sales incentives and volume rebates to customers are classified as
selling expenses and are included in selling, general and administrative
expenses.

      Cost of goods sold
      ------------------

      Raw material costs represent a large portion of the Company's cost of
goods sold and are susceptible to price fluctuations based upon supply and
demand and general market conditions. Beginning in April 1994 and continuing
through August 1995, prices of raw materials reached historically high levels.
Since that time, raw material prices have declined and are near early 1994
levels. Although future raw material prices cannot be predicted with accuracy,
the prices for the raw materials used in the Company's products are forecasted
by independent industry surveys and producer reports to remain stable or decline
over the next several years.

     In connection with the Company's engineering initiatives, the Company has
invested significant resources in research and development. The Company expenses
all research and development costs in the period incurred and includes such
costs in cost of goods sold. As a percentage of net sales, these costs have
represented 0.9%, 1.3% and 1.8% in 1995, 1996 and 1997, respectively.

                                       11
<PAGE>
 
      Distribution expense

      The Company ships its products from manufacturing locations using a
combination of common carriers, its own fleet and leased vehicles. Distribution
expense consists of the costs to ship products, including costs of labor and
leased vehicles.

      Restructuring charges

      During the first quarter of 1996, the Company closed its Des Plaines,
Illinois manufacturing facility and consolidated those operations into its West
Chicago, Illinois facility. In addition, the Company consolidated certain
warehousing facilities and relocated its executive offices to Radnor,
Pennsylvania. The plant and warehouse consolidations, together with the
relocation of its executive offices, resulted in $910,000 of restructuring
charges expensed and paid during the year ended December 27, 1996.

      Net operating loss carryforwards

      As of December 26, 1997, the Company had approximately $20.5 million of
net operating loss carryforwards for federal income tax purposes, which expire
through 2012. A valuation allowance was provided for substantially all of the
loss carryforward tax benefit at December 27, 1996. In 1997, as a result of
management's reevaluation of the Company's future profit outlook, the valuation
allowance has been eliminated and a tax benefit of $4.8 million has been
reflected in the 1997 financial statements. See Note 7 to the Company's 
consolidated financial statements included herein.

      Pending accounting changes

      In July 1997, the FASB issued Statement No. 130, "Reporting Comprehensive
Income", and Statement No. 131, "Disclosures About Segments of an Enterprise and
Related Information". Statement No. 130 establishes standards for reporting
comprehensive income in financial statements. Statement No. 131 expands certain
reporting and disclosure requirements for segments from current requirements.
The Company is not required to adopt these Statements until 1998 and is
currently evaluating the impact, if any, these new standards will have on its
financial reporting practices.

      Year 2000 Compliance

      The Company is currently in the process of evaluating its information
technology infrastructure for Year 2000 compliance. The Company does not
expect that the cost to modify its information technology infrastructure to be
Year 2000 compliant will be material to its financial condition or results of
operations. The Company does not anticipate any material disruptions in its
operations as a result of any failure by the Company to be in compliance. The
Company does not currently have any information concerning the Year 2000
compliance status of its suppliers and customers. In the event that any of the
Company's significant suppliers or customers does not successfully and timely
achieve Year 2000 compliance, the Company's business operations could be
adversely affected.

      Comparability of Periods

      Financial results for 1995, 1996 and 1997 are not fully comparable to each
other because of the January 1996 acquisition of the U.S. foam container
operations of Fort James Corporation, formerly James River Paper Company, Inc.
("J.R. Cup"), the December 1996 acquisition of StyroChem and the October 1997
acquisition of StyroChem Europe.

Results of Operations

      The following discussion and analysis should be read in conjunction with
Item 6, "Selected Financial Data" and Item 8, "Financial Statements and
Supplementary Data" included elsewhere herein.

Year Ended December 26, 1997 Compared to Year Ended December 27, 1996

     Net sales increased to $243.6 million for 1997 from $177.4 million for
1996, an increase of $66.2 million or 37.3%. The increase was due primarily to
the acquisition of StyroChem Europe on October 15, 1997 and the acquisition of
StyroChem on December 5, 1996, as well as growth in the foam packaging business.

     Cost of goods sold decreased to 74.5% of net sales for 1997, from 76.7% of
net sales in 1996. The decline in cost of goods sold as a percentage of sales
was due primarily to reductions in manufacturing overhead as a percentage of net
sales resulting from the acquisition of StyroChem Europe and a decline in raw
material prices resulting from improved market conditions.

     Gross profit increased to $62.2 million or 25.5% of net sales for 1997,
from $41.4 million or 23.3% of net sales in 1996.

     Distribution expense as a percentage of net sales decreased to 7.4% for
1997, from 7.9% of net sales in 1996. This decline in distribution expense as a
percentage of net sales was due primarily to the acquisitions of StyroChem and
StyroChem Europe, which had distribution expense as a percentage of net sales of
3.3% and 7.3% in 1997, respectively.

     Selling, general and administrative expenses increased to $30.1 million or
12.4% of net sales for 1997, from $18.7 million or 10.5% of net sales in 1996.
The increase in selling, general and administrative costs as a percentage of net
sales is attributable to the acquisition of StyroChem Europe, which had selling,
general and administrative expenses as a percentage of net sales of 13.9%, and
an increase in commissions related to retail sales.

     Income from operations increased to $14.0 million or 5.7% of net sales for
1997, from $7.7 million or 4.4% of net sales in 1996.

     Interest increased to $13.0 million for 1997, from $4.5 million in 1996.
This increase was due primarily to an increase in borrowings related to the
acquisitions of J.R. Cup, StyroChem and StyroChem Europe, including the issuance
of the Series A Notes and Series B Notes.

     Income taxes were a benefit of $2.5 million for 1997, compared to an
expense of $0.1 million in 1996. The benefit from income taxes in 1997 relates
to the elimination of the valuation allowance previously provided for net
operating loss carryforwards, partially offset by income taxes of $2.3 million
in 1997.

     Net income increased to $3.6 million or 1.5% of net sales for 1997, from
$1.4 million or 0.8% of net sales for the same period in 1996 due to the reasons
described above.

Year Ended December 27, 1996 Compared to Year Ended December 29, 1995

     Net sales for 1996 were $177.4 million, more than double the net sales of
$86.2 million for 1995. The increase was due primarily to the acquisitions of
J.R. Cup on January 20, 1996 and StyroChem on December 5, 1996.

     Costs of goods sold decreased as a percentage of net sales to 76.7% for
1996, from 87.8% in 1995. The decline in cost of goods sold as a percentage of
net sales was due primarily to a decline in raw material prices resulting from
improved market conditions, the increased purchasing power of the combined
company and reductions in manufacturing overhead as a result of the J.R. Cup
acquisition.

     Gross profit increased to $41.4 million or 23.3% of net sales for 1996,
from $10.5 million or 12.2% of net sales in 1995. The increase in gross profit
as a percentage of net sales was due primarily to lower raw material prices and
cost reductions related to the J.R. Cup acquisition.

                                       13
<PAGE>
 
     Distribution expense increased to $14.1 million or 7.9% of net sales for
1996, from $6.0 million or 7.0% of net sales in 1995. The increase in
distribution expense as a percentage of net sales was due primarily to rate
increases by freight carriers and a higher percentage of consumer sales, which
require greater delivery costs. The Company also temporarily incurred additional
freight costs as a result of a plant closure and the realignment of customer
shipping locations.

     Selling, general and administrative expenses increased to $18.7 million or
10.5% of net sales for 1996, from $9.1 million or 10.5% of net sales in 1995.
Selling, general and administrative expenses were fairly constant as a
percentage of net sales.

     Income (loss) from operations increased to $7.7 million or 4.4% of net
sales for 1996, from a loss from operations of $4.5 million in 1995. As noted
above, during 1996, the Company recorded restructuring charges of $0.9 million,
due primarily to a plant closure and the relocation of its executive offices.

     Interest increased to $4.5 million or 2.5% of net sales for 1996, from $2.8
million or 3.3% of net sales in 1995 due primarily to an increase in borrowings
related to the acquisitions of J.R. Cup and StyroChem.

     Other expense, net decreased to $0.4 million or 0.2% of net sales for 1996
from $0.5 million or 0.6% of net sales in 1995.

     Income (loss) from continuing operations increased to $1.4 million or 0.8%
of net sales for 1996, from a loss from continuing operations of $7.9 million in
1995, for the reasons outlined above.

Liquidity and Capital Resources

     During fiscal years 1996 and 1997, the Company's principal sources of funds
consisted of cash from operations and financing sources. During the year ended
December 26, 1997, after tax cash flow increased to $12.2 million, while working
capital provided cash of $0.8 million. Additional borrowings under the credit
facilities of $12.7 million and proceeds from the Series B Note offering, offset
by an increase in cash of $8.0 million, were used to fund capital expenditures
of $18.4 million, a dividend payment of $3.0 million and the acquisition of
StyroChem Europe in the amount of $52.3 million. The Company has managed its
growth in working capital and capital expenditures through a combination of
working capital financing and proceeds of long-term debt financing.

     As of December 26, 1997, the Company had $16.8 million outstanding and
$15.1 million available under its revolving credit agreements. The Company's
principal uses of cash for the next several years will be working capital
requirements and capital expenditures. The Company's capital expenditures for
fiscal years 1995, 1996 and 1997 were $5.5 million, $4.9 million and $18.4
million, respectively. By completing the sale of the Series A Notes and the
Series B Notes, and by entering into its revolving credit agreements, the
Company believes that it has increased its flexibility over the next five years
to make capital expenditures that management believes will provide an attractive
return on investment.

     On October 15, 1997, the Company issued $60.0 million of Series B Notes.
The net proceeds to the Company from the offering in the amount of $60.6 million
were used to repay existing indebtedness under the Company's revolving credit
agreements and to finance the acquisition of StyroChem Europe. The Company also
amended its current credit facility, which increased the aggregate commitment to
$40.0 million and included a $10.0 million sub-limit for the StyroChem Europe
subsidiaries.

     The Company has had an increase in annual debt service requirements from
historical levels, due primarily to the acquisitions of StyroChem Europe,
StyroChem and J.R. Cup. As a holding company, the Company is dependent upon
dividends and other payments from its subsidiaries to generate the funds
necessary to meet its obligations. Subject to certain limitations, the Company
is, and will continue to be, able to control its receipt of dividends and other
payments from its subsidiaries. Management believes that cash generated from
operations, together with available borrowings under its revolving credit
facilities will be sufficient to meet the Company's expected operating needs,
planned capital expenditures and debt service requirements. However, there can
be no assurance 

                                       14
<PAGE>
 
that sufficient funds will be available from operations or borrowings under its
credit agreements to meet the Company's cash needs.

     The statements contained in this Annual Report that are not historical
facts, including but not limited to the Company's plans for expansion, facility
consolidation, acquisition and raw material prices, are based on current
expectations. These statements are forward looking (as defined in the U.S.
Private Securities Litigation Reform Act of 1995) in nature and involve a number
of risks and uncertainties. Actual results may vary materially due to risks
relating to raw material price volatility, dependence on key customers,
international operations, dependence on key personnel and environmental matters,
as well as general business and economic conditions, both domestic and
international, and other risks that may be described from time to time in the
reports that the Company files with the Securities and Exchange Commission. See

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS




To Radnor Holdings Corporation:


We have audited the accompanying consolidated balance sheets of Radnor Holdings
Corporation (a Delaware corporation) and subsidiaries as of December 27, 1996
and December 26, 1997, and the related consolidated statements of income,
stockholders' (deficit) equity and cash flows for each of the three years in the
period ended December 26, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits 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 present fairly, in
all material respects, the financial position of Radnor Holdings Corporation and
subsidiaries as of December 27, 1996 and December 26, 1997, and the results of
their operations and their cash flows for each of the three years in the period
ended December 26, 1997, in conformity with generally accepted accounting
principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  ------------------------------------------


1.  ORGANIZATION, ACQUISITIONS AND DISCONTINUED OPERATIONS:
    ------------------------------------------------------ 

The Company
- -----------

Radnor Holdings Corporation ("Radnor") was incorporated in Delaware on November
6, 1991 to acquire the outstanding stock of Benchmark Holdings, Inc.
("Benchmark") and WinCup Holdings, Inc. ("WinCup"). Radnor, through its WinCup
subsidiary, is the second largest producer in the United States of foam cups and
containers for the foodservice industry. Through its Radnor Chemical Corporation
subsidiary, Radnor is the fifth largest worldwide producer of expandable
polystyrene ("EPS"). Radnor and its subsidiaries (collectively the "Company")
sell their products primarily to national, institutional, retail and
wholesale customers throughout the U.S., Canada, Mexico, and Europe. The Company
markets their products under a variety of brand and trade names, including
"WinCup", "Handi-Kup", "StyroChem" and "ThermiSol."

The Company has a number of large national accounts and supplies products to a
number of large foodservice distributors. The five largest accounts represented
approximately 37% and 28% of the Company's net sales for fiscal years 1996 and
1997, respectively. Although the Company has not lost sales from its key
customers in fiscal years 1996 and 1997, if any of such customers substantially
reduces its level of purchases from the Company, the Company's profitability
could be adversely affected. Moreover, continued consolidation among
distributors in the foodservice industry could result in an increasingly
concentrated customer base or the loss of certain customers.

StyroChem Europe Acquisition
- ----------------------------

On October 15, 1997, the Company acquired the polystyrene production and
conversion operations of Neste Oy ("StyroChem Europe"). The acquisition was
accounted for as a purchase and, accordingly, the purchased assets and assumed
liabilities of StyroChem Europe were recorded at estimated fair values at the
date of acquisition. The purchase price was 213.0 million Finnish Markkas
(approximately $40.8 million as of the date of closing) plus the net working
capital, estimated to be 60.0 million Finnish Markkas (approximately $11.5
million as of the date of closing). The purchase price was allocated to accounts
receivable ($13.8 million), inventory ($6.5 million), property, plant and
equipment ($40.8 million), accounts payable ($6.4 million) and accrued
liabilities ($2.4 million). A portion of the proceeds from the Company's
offering of $60.0 million 10% Series B Senior Notes due 2003 was utilized to
fund the purchase price.

StyroChem Acquisition
- ---------------------

On December 5, 1996, the Company acquired all of the issued and outstanding
capital stock of and other equity interests in Radnor Chemcial Corporation,
formerly SP Acquisition Co. ("StyroChem"), a Delaware corporation. The
acquisition was accounted for as a purchase and, accordingly, the purchased
assets and assumed liabilities of StyroChem were recorded at estimated fair
values at the date of acquisition.

The purchase price consisted of approximately $23.5 million of cash plus $0.9
million of assumed indebtedness and consulting payments. The purchase price was
allocated to cash ($2.4 million), accounts receivable ($11.5 million), inventory
($7.3 million), property, plant and equipment ($23.5 million), other assets
($1.0 million), accounts payable ($16.3 million) and accrued liabilities ($5.0
million). Approximately $1.4 million of the purchase price has been placed in a
separate escrow account, and may be used by the Company to satisfy obligations
associated with specified environmental matters relating to StyroChem's Texas
and Quebec facilities. In addition, the former owner was paid $4.8 million in
connection with a five-year agreement not to compete.

J.R. Cup Acquisition
- --------------------

On January 20, 1996, WinCup entered into an agreement (the "Agreement") with
Fort James Corporation, formerly James River Paper Company, Inc. ("Fort James"),
whereby both parties contributed their fixed assets, leasehold improvements,
technology, patents, trademarks, real property and other noncurrent assets
associated with their foam cup and container and thermoformed lid manufacturing
operations and all inventory, spare parts and other current assets, excluding
cash and accounts receivable to WinCup Holdings, L.P. This new entity was
structured as a Delaware limited partnership with WinCup as the sole general
partner and Fort James as the sole limited partner. Ownership interests were
allocated 55% to WinCup and 45% to Fort James. The WinCup contribution of assets
and liabilities was accounted for at historical cost.

The acquisition of assets and liabilities from Fort James has been accounted for
as a purchase by the partnership in accordance with APB Opinion No. 16 and,
accordingly, the assets and liabilities of Fort James have been recorded at
estimated fair values at the date of the purchase. The purchase price consisted
of approximately (i) $19.1 million of cash, (ii) $16.8 million of promissory
notes (Note 3), (iii) the assumption of $1.0 million of liabilities and (iv) the
45% equity interest in the partnership valued at $17.7 million. This partnership
equity transaction resulted in an increase in WinCup's pro rata share (55%) of
the underlying equity in the partnership which has been recorded as an addition
to paid-in capital. The purchase price was allocated to inventories ($8.2
million) and property, plant and equipment ($46.4 million). At January 20, 1996
the minority interest in the partnership was reflected in the Company's
consolidated balance sheet at approximately $9.1 million. For the period January
20, 1996 through December 5, 1996, the minority interest (45%) in the income of
the partnership was approximately $1.3 million and this amount has been
reflected in the consolidated statement of operations.

Pursuant to the Agreement, the Company had the option to acquire Fort James's
partnership interest at the times and for the applicable prices set forth in the
Agreement, 
                                      F-8
<PAGE>
 
ranging from $15.0 million at January 20, 1996, to $37.3 million at
January 20, 2001. Furthermore, Fort James could at any time beginning on the
fifth anniversary of the Agreement have required the Company to acquire its
interest for $37.3 million. On December 5, 1996, Radnor exercised the option and
acquired the 45% partnership interest from Fort James. The price paid by Radnor
to acquire the 45% interest exceeded the carrying value of the minority interest
by approximately $7.3 million, and this amount has been allocated to fixed
assets in the consolidated balance sheet as of December 27, 1996.

Pro Forma Results of Operations

Operating results of the acquired businesses are included in consolidated
results only from the date of acquisition. Unaudited pro forma data reflecting
results as if the acquisitions were effective at the beginning of 1996 follow
(in thousands):

       Income before extraordinary item                3,606             6,811

Pro forma results are unaudited and are based on historical results, adjusted
for the impact of certain acquisition related items, such as: increased
depreciation of property, plant and equipment, increased interest expense on
acquisition debt, and the related income tax effects. Pro forma results do not
reflect any synergies that might be achieved from combined operations and
therefore, in management's opinion, are not indicative of what actual results
would have been if the acquisitions had occurred at the beginning of 1996. In
addition, they are not intended to be a projection of future results.

Discontinued Operations
- -----------------------

Pursuant to an Asset Purchase Agreement among Benchmark, WinCup and Fort James
dated as of October 31, 1995, Benchmark and WinCup agreed to sell to Fort James
all of the assets of Benchmark's cutlery and straws business and all of the
assets of WinCup's thermoformed cup business, except for cash, accounts
receivable and prepaid assets. The only liabilities of Benchmark and WinCup
assumed by Fort James were obligations arising after the closing under the
assumed leases and assumed material contracts and vacation pay, holiday pay and
sick pay earned or accrued during 1995. The sale price was $51.0 million. The
gain on the sale was approximately $2.0 million.

The operations of Benchmark's cutlery and straws business and WinCup's
thermoformed cup business have been accounted for as discontinued operations in
the accompanying consolidated financial statements.

The Company used a portion of the proceeds from the sale to retire certain
outstanding debt totaling approximately $48.0 million. An additional $23.8
million of principal and accrued interest was forgiven by the bank lender as
part of this transaction. As a result, at the closing of this transaction, the
total amount of debt outstanding to the Company's primary bank was reduced to
$9.0 million. During 1996, the bank was paid $8.3 million in full satisfaction
of this obligation. The extinguishment gains resulting from these transactions
have been presented as extraordinary items in the accompanying financial
statements.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
    ------------------------------------------

Fiscal Year
- -----------

The Company's fiscal year is the fifty-two or fifty-three week period which ends
on the last Friday of December of each year. The fiscal years ended December 29,
1995, December 27, 1996 and December 26, 1997 are fifty-two week periods.

Principles of Consolidation
- ---------------------------

The accompanying consolidated financial statements include the accounts of
Radnor and all of its majority-owned subsidiaries. All material intercompany
balances and transactions have been eliminated in consolidation. Certain
reclassifications were made to the prior year financial statements to conform to
the 1997 presentation. The equity method of accounting is used when the Company
has a 20% to 50% ownership interest in other companies. Under the equity method,
original investments are recorded at cost and adjusted for the Company's share
of undistributed earnings or losses of these companies.

Accounts Receivable, Net
- ------------------------

Accounts receivable are net of allowances for doubtful accounts of $713,000 and
$829,000 at December 27, 1996 and December 26, 1997, respectively. Bad debt 
expense was $135,000, $120,000 and $179,000 for fiscal years 1995, 1996 and 
1997, respectively. The related writeoffs of accounts receivable were $57,000, 
$112,000 and $63,000 for those years, respectively. Additional a reserve of 
$209,000 was acquired in 1996 as part of the StyroChem Acquisition.

Inventories
- -----------

Inventories are recorded at the lower of cost (first-in, first-out) or market.
Inventories at December 27, 1996 and December 26, 1997, consist of the following
(in thousands):

                                                     1996             1997

       Finished goods                                  12,333           17,536
                                               --------------   --------------
                                      
                                               $       19,078   $       28,451
                                               ==============   ==============

Property, Plant and Equipment
- -----------------------------

Property, plant and equipment are stated at cost and depreciated using the
straight-line method over estimated useful lives which range from 5 to 40 years.
Leasehold improvements are amortized over the lesser of their estimated useful
lives or the term of the lease using the straight-line method. Maintenance and
repairs are charged to operations currently, and replacements and significant
improvements are capitalized. Depreciation expense in fiscal 1995, 1996, and
1997 was $2,057,000, $4,451,000 and $7,504,000, respectively.

Supplies and Spare Mold Parts
- -----------------------------

Supplies and spare mold parts include maintenance parts maintained in a central
stores location. When needed at the manufacturing facilities, parts are shipped
and expensed.

Other Assets
- ------------

Other assets include deferred financing costs of $3.8 million and $6.8 million
as of December 27, 1996 and December 26, 1997, respectively, related to the
financing arrangements and note offerings executed in 1996 and 1997. Such costs
are being amortized over the terms of the related debt instruments. Amortization
of deferred financing costs of $232,000 and $836,000 is included in interest
expense for the years ended December 27, 1996 and December 26, 1997,
respectively. In addition, other assets include a noncompete agreement of $3.8
million, net of amortization of $1.0 million, resulting from the StyroChem
Acquisition, which is being amortized over five years.

Environmental Expenditures
- --------------------------

Environmental expenditures that relate to an existing condition caused by past
operations and that do not contribute to current or future revenue generation
are expensed. Liabilities are recorded when environmental assessments and/or
cleanups are probable, and the costs can be reasonably estimated.

                                      F-11
<PAGE>
 
Income Taxes
- ------------

The Company accounts for income taxes under the liability method. Under this
method, deferred tax assets and liabilities are recognized for the tax effects
of temporary differences between the financial reporting and tax bases of assets
and liabilities using enacted tax law and statutory tax rates applicable to the
periods in which the temporary differences are expected to affect taxable
income.

Revenue Recognition
- -------------------

Revenue is recognized when goods are shipped.

Currency Translation
- --------------------

The Company conducts business in a number of foreign countries and as a result
is subject to the risk of fluctuations in foreign currency exchange rates and
other political and economic risks associated with international business. The
Company's foreign entities report their assets, liabilities and results of
operations in the currency in which the entity primarily conducts its business.
Adjustments resulting from the translation of the financial statements are
reflected as a currency translation adjustment in stockholders' equity. Currency
transaction gains and losses, which are included in operating results, are not
significant.

Research and Development
- ------------------------

Research and development costs are charged to expense as incurred and are
included in cost of goods sold. These costs have represented 0.9%, 1.3% and 1.8%
of net sales in 1995, 1996 and 1997, respectively.

Use of Estimates
- ----------------

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Fair Value of Financial Instruments
- -----------------------------------

The estimated fair value of financial instruments was determined by the Company
using market quotes, if available, or discounted cash flows using market
interest rates. The carrying values of cash, accounts receivable, accounts
payable and accrued liabilities approximate fair value due to the short-term
nature of these items. The carrying amounts of the Company's bank term loan and
the lines of credit approximate fair value because they have variable interest
rates based on either the prime rate or LIBOR. The fair value of the senior
notes was $166 million at December 26, 1997.

      under the Amended Credit Agreement will mature on October 15, 2002. 
      All the obligations of the Company under the Amended Credit Agreement

On October 15, 1997, the Company completed a $60 million Series B Senior Note
offering. The proceeds were used to finance the StyroChem Europe acquisition and
repay a portion of the outstanding principal and accrued interest under the
revolving credit facility.

On December 5, 1996, the Company completed a $100 million Series A Senior Note
offering. The proceeds were used to (i) repay existing indebtedness, including
amounts outstanding under the Term Note, Revolver, the various subordinated
notes and mortgage note payable; (ii) repay certain J.R. Cup acquisition
obligations; (iii) redeem the outstanding redeemable convertible Preferred stock
and warrants; (iv) finance the StyroChem Acquisition; and, (v) provide working
capital.

On October 15, 1997, the Company also entered into the Second Amended Credit
Agreement with two banks, as agents and lenders, pursuant to which the Amended
and Restated Revolving Credit and Security Agreement dated as of December 5,
1996 was amended and restated. The Amended Credit Agreement includes the Company
and certain of its U.S. subsidiaries as borrowers. The Amended Credit Agreement
provides for a fee of 0.375% per annum on the undrawn amount of the credit
facility and letter of credit fees of 1.75% or 1.5% of the aggregate face
amounts of standby letters of credit and documentary letters of credit,
respectively. There is a $5 million sublimit on standby letters of credit and a
$1 million sublimit on documentary letters of credit. At December 27, 1996 and
December 26, 1997, the Company had outstanding $1.7 million and $1.9 million of
letters of credit, respectively.

Each of the above agreements contain certain restrictive covenants which
include, among other things, restrictions on the declaration or payment of
dividends, the repurchase of stock, the incurrence of additional debt, the
amount of capital expenditures and additional investments and the sale or
disposition of assets. The Company is also required to maintain a minimum net
worth and certain financial ratios including debt to equity, current, debt
coverage and earnings to interest expense. The Company is currently in
compliance with all financial covenants.

Rental expense for all operating leases was $4,545,000, $4,148,000 and
$6,144,000 for fiscal years 1995, 1996 and 1997, respectively.

Litigation
- ----------

The Company is involved in various legal actions arising in the normal course of
business. After taking into consideration legal counsel's evaluation of such
actions, management believes that these actions will not have a material effect
on the Company's financial position or results of operations.

Supply Agreements
- -----------------

In December 1996, in connection with the StyroChem Acquisition, the Company
renegotiated its contract with Chevron Chemical Company to provide a long-
term supply of styrene monomer with volume discounts. The initial term of the
new contract extends for seven years. Under the contract, the Company is
required to purchase the first 120 million pounds of its domestic styrene
monomer requirements per year from Chevron and has certain rights to purchase
additional styrene monomer.

In October 1997, in connection with the StyroChem Europe Acquisition, the
Company negotiated a contract with Elf AtoChem S.A. to provide a long-term
supply of styrene monomer at a reduced price and with volume discounts. The
initial term of the new agreement extends for three years. Under the agreement,
StyroChem Europe has the right to purchase up to 110 million pounds of styrene
monomer per year.

5. STOCKHOLDERS' EQUITY:
   --------------------

The Company is currently authorized to issue up to 11,650 shares of Voting
Common Stock, 5,400 shares of Class B Nonvoting Common Stock, 5,650 shares of
Nonvoting Common Stock and 2,000 shares of series Preferred stock. At December
26, 1997, there are issued and outstanding 600 shares of Voting Common Stock, 
5,400 shares of Class B

                                      F-15
<PAGE>
 
Nonvoting Common Stock and 245 shares of Nonvoting Common Stock. All shares have
a par value of $.10 except for shares of Class B Nonvoting Common Stock, which
have a par value of $.01. In October 1996, the Company completed a
recapitalization in which each outstanding share of Voting Common Stock was
converted into 0.1 shares of Voting Common Stock and 0.9 shares of Class B
Nonvoting Common Stock.

The Company's principal stockholder transferred ownership of 60 shares of Voting
Common Stock and 540 shares of Class B Nonvoting Common Stock to an officer of
the Company, and the estimated fair value of such stock has been reflected as
compensation expense in the 1997 financial statements.

6.  RESTRUCTURING CHARGES:
    ---------------------

In connection with the J.R. Cup Acquisition, the Company incurred certain
restructuring costs related principally to plant closures and severance
payments. These costs were incurred and paid during the year ended December 27,
1996.

As of December 26, 1997, the Company had approximately $20.5 million of net
operating loss carryforwards for federal income tax purposes, which expire
through 2012. A valuation allowance was provided for substantially all of the
loss carryforward tax benefit at December 27, 1996. In 1997, as a result of
management's reevaluation of the Company's future profitability outlook, the
valuation allowance has been eliminated and a tax benefit of $4.8 million has
been reflected in the 1997 financial statements.

8.  STOCK OPTION PLAN:
    -----------------

The 1992 Equity Incentive Plan (the "Plan") provides for the grant of non-
qualified options to purchase shares of the Nonvoting Common Stock subject to
certain limitations. Non-qualified stock options are issuable only to eligible
officers and employees of the Company. The Company has reserved 1,249 shares of
its Nonvoting Common Stock for issuance under the Plan.

                                      F-17
<PAGE>
 
The per share exercise price of a stock option may not be less than 75% of the
fair market value of the Nonvoting Common Stock, as determined by the board of
directors, on the date the option is granted. Such options may be exercised only
if the option holder remains continuously associated with the Company from the
date of grant to a date not less than three months prior to the date of
exercise. The exercise date of an option granted under the plan cannot be later
than ten years from the date of the grant. Any options that expire unexercised
or that terminate upon an optionee's ceasing to be employed by the Company
become available once again for issuance.

The following summarizes the stock option activity under the Plan:

</TABLE> 

The exercise price for all options granted prior to 1997 is $3,350 per share
while the exercise price for all shares granted during 1997 is $6,985. These
amounts represent the fair market value as determined by the board of directors
on the grant dates.

The Company applies Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees," and related interpretations in accounting for its
stock options plans. Accordingly, no compensation expense has been recognized
related to the plans described above. If compensation cost for these plans had
been determined using the fair-value method prescribed by SFAS No. 123,
"Accounting for Stock Based Compensation," the Company's net income would have
been reduced to the pro forma amounts indicated below.


                      (in thousands)                          1997

                      Net income - pro forma                    3,492

This pro forma impact may not be representative of the effects for future years
and is likely to increase as additional options are granted and amortized over
the vesting period.

As the Company's stock is not publicly traded, the fair value of each option was
estimated on the grant date using the minimum value method (which excludes a
volatility assumption), with the following assumptions:

                                                                    EXHIBIT 3.13

                         CERTIFICATE OF INCORPORATION

                                      OF

                             RADNOR DELAWARE, INC.

       FIRST:     The name of the corporation is RADNOR DELAWARE, INC.

       SECOND:    The registered office of the corporation in the State of
Delaware is located at 1209 Orange Street, Wilmington, Delaware, 19801, County
of New Castle.  The registered agent of the corporation at that address is The
Corporation Trust Company.

       THIRD:     The purpose of the corporation is to engage in any lawful act
or activity for which corporations may be organized under the General
Corporation Law of the State of Delaware; provided that the corporation's
activities shall be confined to the maintenance and management of its intangible
investments and the collection and distribution of the income from such
investments or from tangible property physically located outside Delaware, all
as defined in such manner to qualify for exemption from income taxation under,
Section 1902(b)(8) of Title 30 of the Delaware Code, or under the corresponding
provision of any subsequent law.

       FOURTH:    The corporation shall have authority to issue One Thousand
(1,000) shares of common stock, having a par value of $.001 per share.

       FIFTH:     The corporation shall indemnify directors and officers of the
corporation to the fullest extent permitted by law.

       SIXTH:     The directors of the corporation shall incur no personal
liability to the corporation or its stockholders for monetary damages for any
breach of fiduciary duty as a director; provided, however, that the directors of
the corporation shall continue to be subject to liability (i) for any breach of
their duty of loyalty to the corporation or its stockholders, (ii) for acts or
omissions not in good faith or which
<PAGE>
 
involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the General Corporation Law of the State of Delaware, or (iv) for
any transaction from which the directors derived an improper personal benefit.
In discharging the duties of their respective positions, the board of directors,
committees of the board, individual directors and individual officers may, in
considering the best interest of the corporation, consider the effects of any
action upon employees, suppliers and customers of the corporation, communities
in which officers or other establishments of the corporation are located, and
all other pertinent factors. In addition, the personal liability of directors
shall further be limited or eliminated to the fullest extent permitted by any
future amendments to Delaware law.

       SEVENTH:   The business and affairs of the corporation shall be managed
by or under the direction of the board of directors, the number of members of
which shall be set forth in the bylaws of the corporation.  The directors need
not be elected by ballot unless required by the bylaws of the corporation.

       EIGHTH:    Meetings of the stockholders will be held within the State of
Delaware.  The books of the corporation will be kept (subject to the provisions
contained in the General Corporation Law) in the State of Delaware at such place
or places as may be designated from time to time by the board of directors or in
the bylaws of the corporation.

       NINTH:     In the furtherance and not in limitation of the object,
purposes and powers prescribed herein and conferred by the laws of the State of
Delaware, the board of directors is expressly authorized to make, amend and
repeal the bylaws.

       TENTH:     The corporation reserves the right to amend or repeal any
provision contained in this Certificate of Incorporation in the manner now or
hereinafter prescribed by the laws of the State of Delaware.  All rights herein
conferred are granted subject to this reservation.

       ELEVENTH:  The corporation shall have no power and may not be authorized
by its stockholders or directors (i) to perform or omit to do any act that would
prevent, inhibit, or cause the corporation to lose its status as a corporation

                                      -2-
<PAGE>
 
exempt from the Delaware Corporation Income Tax under Section 1902(b)(8) of
Title 30 of the Delaware Code, or under the corresponding provision of any
subsequent law, or (ii) to conduct any activities in any state other than
Delaware which could result in the corporation being subject to the taxing
jurisdiction of any state other than Delaware.

       TWELFTH:   The name and mailing address of the incorporator is Donna
Juhrden, 314 South State Street, Dover, Delaware 19901.

       THIRTEENTH:  The powers of the incorporator shall terminate upon the
election of directors.

       I, THE UNDERSIGNED, being the incorporator, for the purpose of forming a
corporation under the laws of the State of Delaware do make, file and record
this Certificate of Incorporation, and, accordingly, have hereunto set my hand
and seal this 12th day of January, 1998.

                              ARTICLE 1  OFFICES
     
     SECTION 1.1  The Corporation shall have and maintain in the State of 
Delaware a registered office which may, but need not be, the same as its place
of business.

                            ARTICLE 2  STOCKHOLDERS

     SECTION 2.1  All meetings of the stockholders shall be held at such place
within the State of Delaware, and at such date and time as may be designated by
the Board of Directors and as shall be specified in the notice of the meeting or
in a duly executed waiver of notice thereof.

     SECTION 2.2  An annual meeting of the stockholders, for the election of
directors and for the transaction of such other business as may properly be
brought before the meeting, shall be held at such place within the State of
Delaware and at such, date and time as the Board of Directors may designate and
as shall be specified in the notice of the meeting or in a duly executed waiver
of notice thereof.

     SECTION 2.3  Special meetings of the stockholders, for any purpose or
purposes, may be called by the Board of Directors or the President and shall be
called by the President or the Secretary at the request in writing of a majority
of the members of the Board of Directors then in office. Such request shall
state the purpose or purposes
<PAGE>
 
of the proposed meeting. Business transacted at all special meetings shall be
confined to the objects stated in the notice thereof.

     SECTION 2.4  Written notice of any annual or special meeting of
stockholders shall be mailed to each stockholder entitled to vote thereat at his
address as it appears on the records of the Corporation, not fewer than ten nor
more than sixty days before the date of such meeting. Such notice shall be
deemed to be given when deposited in the United States mail, postage prepaid,
directed to each stockholder at his address as it last appears on the records of
the Corporation. Such notice shall state the place within the State of Delaware
and the date and hour of the meeting, and, in the case of a special meeting,
shall state the purpose or purposes for which the meeting is called.

     SECTION 2.5  At any meeting of the stockholders, the holders of a majority
of all of the issued and outstanding shares of stock entitled to vote at the
meeting, present in person or by proxy, shall constitute a quorum for all
purposes, except to the extent that the presence of a larger number of
stockholders may be required by law, by the Certificate of Incorporation of the
Corporation or by these By-laws. If a quorum shall fail to be present or
represented at any meeting, the chairman of the meeting or the holders of a
majority of the shares of the stock entitled to vote who are present, in person
or by proxy, may adjourn the meeting to another place, date or time. When a
meeting is so adjourned, written notice need not be given of the adjourned
meeting if the place, date and time thereof are announced at the meeting at
which the adjournment is taken; provided, however, that if the date of any 
adjourned meeting is more than thirty days after the date for which the meeting
was

                                      -2-
<PAGE>
 
originally noticed, or if a new record date is fixed for the adjourned meeting,
written notice of the place, date, and time of the adjourned meeting shall be
given in conformity herewith. At any adjourned meeting, any business may be
transacted that might have been transacted at the original meeting.

     SECTION 2.6  At any meeting of the stockholders, every stockholder entitled
to vote may vote in person or by proxy authorized by an instrument in writing or
any complete and reliable copy, facsimile telecommunication or other
reproduction of the writing executed by such stockholder or by an authorized
officer, director, employee or agent of such stockholder, to the extent
permitted by law, and submitted to the Secretary at or before such meeting, but
no proxy shall be voted or acted upon after three years from its date, unless
the proxy provides for a longer period.  Each stockholder shall have one vote
for each share of stock entitled to vote that is registered in his name on the
record date for the meeting, except as otherwise provided herein or required by
law.  All elections of directors by the stockholders shall be by written ballot
and shall be determined by a plurality of the votes cast.  All other voting need
not be by written ballot, except upon demand therefor by the Board of Directors
or the officer of the Corporation presiding at the meeting of stockholders where
the vote is to be taken.  When a quorum exists at any meeting, the vote of a
majority of the stock having voting power present in person or represented by
proxy shall decide any question brought before such meeting, unless the question
is one for which, by express provision of law or of the Certificate of
Incorporation of the Corporation or of these By-laws, a different vote is
required.

                                      -3-
<PAGE>
 
     SECTION 2.7    The Board of Directors shall appoint either one or three
inspectors of election, in advance of any meeting of stockholders, to act at
such meeting of the stockholders or any adjournment thereof. Inspectors of
election need not be stock holders, and no person who is a candidate for
corporate office shall act as an inspector of election. If three inspectors of
election are appointed, such inspectors of election shall act by majority vote.
Each inspector of election shall sign an oath faithfully to execute the duties
of inspector with strict impartiality and to the best of the inspector's
ability and shall do all acts as are necessary and proper to conduct the
election or vote and all such other acts as may be prescribed by law with
fairness to all stockholders. Such inspectors of election shall make a written
report of any matter determined by them and shall execute a certificate as to
any fact found by them.

     SECTION 2.8    The chairman of any meeting of the stockholders shall
determine the order of business and the procedure to be followed at such
meeting, including such regulation of the manner of voting and the conduct of
discussion as he shall deem to be fair and equitable.

     SECTION 2.9    The stockholders may participate in any meeting by means of
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear one another, and such
participation shall constitute presence in person at such meeting; provided that
a quorum of stockholders is physically present in the State of Delaware.

     SECTION 2.10   Unless otherwise required by the Certificate of
Incorporation of the Corporation, any action required or permitted to be taken
at any meeting of the stockholders may be taken without a meeting, without prior
notice and without a vote, 

                                      -4-
<PAGE>
 
if a written consent setting forth the action so taken shall be signed by the
holders of outstanding stock having not less than the minimum number of votes
that would be necessary to authorize or take such action at a meeting at which
all shares entitled to vote thereon were present and voted. Prompt notice of the
taking of any corporate action without a meeting by less than unanimous written
consent shall be given in conformity herewith to those stockholders who have not
consented thereto in writing.

                         ARTICLE 3  BOARD OF DIRECTORS

     SECTION 3.1  The business and affairs of the Corporation shall be managed
by or under the direction of a Board of Directors. In addition to the powers
expressly conferred upon the Board of Directors by these By-laws, the Board of
Directors may exercise all powers of the Corporation and perform all lawful acts
as are not required to be exercised or performed by the stockholders pursuant to
law, the Certificate of Incorporation of the Corporation or these By-laws.

     SECTION 3.2  Directors shall be natural persons who need not be
stockholders of the Corporation. The specific number of directors shall be
designated from time to time exclusively by the Board of Directors. In the
absence of any such designation, the Board of Directors shall be composed of one
(1) director. Each director shall be elected for a term of one year and until
his successor is duly elected and qualified, subject, however, to such
director's prior death, resignation, retirement, disqualification or removal
from office. Whenever the authorized number of directors is increased between
annual meetings of the stockholders, a majority of the directors then in office
shall have the power to elect such new directors who shall serve until the next
annual

                                      -5-

meeting of stockholders and until their successors are duly elected and
qualified. Any decrease in the authorized number of directors shall not become
effective until the expiration of the term of the directors then in office
unless, at the time of such decrease, there shall be vacancies on the Board of
Directors that are being eliminated by such decrease.

     SECTION 3.3  Any vacancy on the Board of Directors occurring by reason of
death, resignation, disqualification, removal or other cause may be filled by a
majority of the directors then in office, although less than a quorum, and each
director elected to fill a vacancy shall serve for the unexpired term of his
predecessor and until his successor is duly elected and qualified.

     SECTION 3.4  The organizational meeting of each newly elected Board of
Directors may be held immediately following the stockholders' meeting at which
such directors were duly elected without the necessity of notice to such
directors or at such time, and at such place within the State of Delaware, as
may be fixed by notice or a duly executed waiver of notice thereof.

     SECTION 3.5  Regular meetings of the Board of Directors shall be held
without call or notice at such time, and at such place within the State of
Delaware, as shall from time to time be fixed by the Board of Directors.

     SECTION 3.6  Special meetings of the Board of Directors may be called by
the Chairman of the Board, by the President or by the Secretary upon his own
initiative or upon the written request of a majority of directors then in
office. Notice of the place, within the State of Delaware, and the time and date
of each such special meeting shall be given to each director by whom it is not
waived by mailing written

                                      -6-
<PAGE>
 
notice to each director not less than two days before the meeting or by giving
notice in person or by telephone, telegram or facsimile transmission not less
than twenty-four hours before the meeting. Notice of special meetings of the
Board of Directors need not state the purpose thereof, except as otherwise
expressly provided by law, by the Certificate of Incorporation of the
Corporation, or by these By-laws. Any and all business may be transacted at a
special meeting, unless otherwise indicated in the notice thereof or provided by
law, by the Certificate of Incorporation of the Corporation or by these By-laws.

     SECTION 3.7  Members of the Board of Directors or any committee thereof may
participate in any meeting of the Board of Directors or such committee, as the
case may be, by means of conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
one another, and such participation shall constitute presence in person at such
meeting; provided that a quorum of directors is physically present in the State
of Delaware.

     SECTION 3.8  At any meeting of the Board of Directors, the presence of a
majority of the total number of directors shall constitute a quorum for the
transaction of business, and the vote of a majority of the directors present at
a meeting at which a quorum is present shall be the act of the Board of
Directors, unless otherwise provided by law, by the Certificate of Incorporation
of the Corporation or by these By-laws.  If a quorum shall not be present at any
meeting of the Board of Directors, a majority of the directors present may
adjourn the meeting to any place, date or time, without notice other than
announcement at the meeting, until a quorum shall be present.

     SECTION 3.9   Unless otherwise provided by law, by the Certificate of
Incorporation of the Corporation or these By-laws, any action required or
permitted to be taken at any meeting of the Board of Directors or of any
committee thereof may be taken without a meeting if all members of the Board of
Directors or such committee, as the case may be, consent thereto in writing and
such consent is filed with the minutes of proceedings of the Board of Directors
or committee thereof.

     SECTION 3.10  Directors, in addition to expenses of attendance, shall be
allowed such compensation for their services as directors, including, without
limitation, their services as members of committees of the Board of Directors,
as may be fixed from time to time by the Board of Directors; provided, that
nothing contained in these By-laws shall be construed to preclude any director
from serving the Corporation in any other capacity and receiving compensation
therefor.

     SECTION 3.11  A member of the Board of Directors or of any committee
thereof shall, in the performance of his duties, be fully protected in relying
in good faith upon the books of account or reports made to the Corporation by
any of its officers, or by an independent certified public accountant, or by an
appraiser selected with reasonable care by the Board of Directors or by any
committee thereof, or in relying in good faith upon other records of the
Corporation.

                             ARTICLE 4  COMMITTEES

     SECTION 4.1  The Board of Directors, by a vote of a majority of the whole
Board of Directors, may from time to time designate committees of the Board of
Directors, with such lawfully delegable powers and duties as it thereby confers,
to serve at the pleasure of the Board of Directors and shall, for those
committees and any others provided for herein, elect a director or directors to
serve as a member or members and designate, if it desires, one or more directors
as alternate members who may replace any absent or disqualified member at any
meeting of the committee.  In the absence or disqualification of any member of
any committee and any alternate member in his place, the member or members of
the committee present at any meeting and not disqualified from voting, whether
or not he or they constitute a quorum, may unanimously appoint another member of
the Board of Directors to act at the meeting in the place of any such absent or
disqualified member.  The Board of Directors may, from time to time, suspend,
alter, continue or terminate any committee or the powers and functions thereof.

     SECTION 4.2  The Board of Directors may appoint committees consisting of
officers or other persons, with chairmanships, vice chairmanships and
secretaryships and such duties and powers as the Board of Directors may from
time to time designate and prescribe.  The Board of Directors may from time to
time suspend, alter, continue or terminate any of such committees or the powers
and functions thereof.

     SECTION 4.3  One-third of the members of any committee shall constitute a
quorum unless the committee shall consist of one or two members, in which case
one 

                                      -9-
<PAGE>
 
member shall constitute a quorum. All matters properly brought before any 
committee shall be determined by a majority vote of the members present.

     SECTION 4.4  Any action that may be taken by a committee at a meeting may
be taken without a meeting if all members thereof consent thereto in writing and
such writing is filed with the minutes of the proceedings of such committee.

     SECTION 4.5  Each committee may determine the procedural rules for meeting
and conducting its business and shall act in accordance therewith, except as
otherwise provided by law, by the Certificate of Incorporation of the
Corporation or by these By-laws.  Adequate provision shall be made for notice to
all members of any committee of all meetings of that committee.

                              ARTICLE 5  OFFICERS

     SECTION 5.1  The officers of the Corporation shall consist of a Chairman of
the Board, a President, one or more Vice Presidents, a Secretary and a
Treasurer. Officers shall be appointed from time to time by the Board of
Directors.  No officer except the Chairman of the Board need be a member of the
Board of Directors.  Any number of offices may be held by the same person.

     SECTION 5.2  The Board of Directors may appoint such other officers,
including assistant officers, and agents as it shall deem necessary, who shall
hold their offices for such terms and shall exercise such powers and perform
such duties as shall be determined from time to time by the Board of Directors.

     SECTION 5.3  Each officer shall hold office until his successor is duly
elected and qualified or until his earlier death, resignation, retirement or
removal.  Any officer 

                                      -10-
<PAGE>
 
appointed by the Board of Directors may be removed at any time by the Board of
Directors without prejudice to his contract rights. If the office of any officer
becomes vacant for any reason, such vacancy shall be filled by the Board of
Directors. Any officer appointed to fill such a vacancy shall hold office until
his successor is duly elected and qualified or until his earlier death,
resignation, retirement or removal.

     SECTION 5.4  The Board of Directors may from time to time delegate the
powers or duties of any officer to any other officers or agents, notwithstanding
any provision of these By-laws.

     SECTION 5.5  The Chairman of the Board shall be a director of the 
Corporation. The Chairman of the Board shall preside at all meetings of the
stockholders and of the Board of Directors and shall perform such duties and
have such powers as may from time to time be assigned to him by the Board of
Directors.

     SECTION 5.6  The President shall be the chief executive officer of the
Corporation and, subject to the provisions of these By-laws and to the
direction of the Board of Directors, he shall have responsibility for the
general management and control of the business and affairs of the Corporation.
Unless otherwise directed by the Board of Directors from time to time, the
President shall have the power to vote and otherwise act on behalf of the
Corporation, in person or by proxy, at any meeting of stockholders of or with
respect to any action of stockholders of any other corporation in which the
Corporation may hold securities and otherwise to exercise any and all rights and
powers which the Corporation may possess by reason of its ownership of
securities in such other corporation.  The President shall perform the duties
and exercise the powers of the Chairman of the Board in the absence or
disability of the 

                                      -11-
<PAGE>
 
Chairman.

     SECTION 5.7  Each Vice President shall have such powers and perform such
duties as may be delegated to him by the Board of Directors or by the President.
In the absence or disability of the Chairman of the Board and the President, any
Vice President who is also a director of the Corporation may preside at meetings
of the stockholders and the Board of Directors to the extent and in the manner
authorized by a resolution of the Board of Directors.

     SECTION 5.8  The Secretary shall attend all meetings of the Board of
Directors and of the stockholders and shall record all votes and the minutes of
all proceedings at such meetings in a book to be kept for that purpose and shall
perform such other duties as the Board of Directors may from time to time

the Board of Directors upon the request of the Board of Directors or such
committee. The Secretary shall give or cause to be given notice of all meetings
of the stockholders and the Board of Directors. The Secretary shall have charge
of the seal of the Corporation, and, where required, shall have the authority to
affix such seal to any instrument. In the absence or disability of the
Secretary, any Assistant Secretary shall perform the duties and exercise the

     SECTION 5.9  The Treasurer shall have the custody of the Corporation's
funds and securities and shall deposit all monies and other valuable effects in
the name and to the credit of the Corporation, in such depositories as may be
designated by the Board of Directors. The Treasurer shall make such
disbursements of the Corporation's funds as are authorized by the Board of
Directors or by the President, taking proper

                                      -12-
<PAGE>
 
vouchers for such disbursements, and shall render to the Board of Directors an
account of all such transactions and of the financial condition of the
Corporation, at such times as the Board of Directors may require. The Treasurer
shall also perform such other duties as the Board of Directors may from time to
time prescribe. In the absence or disability of the Treasurer, any Assistant
Treasurer shall perform the duties and exercise the powers of the Treasurer.

                          ARTICLE 6  INDEMNIFICATION

     SECTION 6.1  Subject to Section 6.3 hereof, the Corporation shall indemnify
any person who was or is a party or has threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the Corporation) by reason of the fact that he is or was a director,
officer or employee of the Corporation, or is or was serving at the request of
the Corporation as a director, officer or employee of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in, or not opposed to, the best interests of the Corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
his conduct was unlawful.  The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a 

                                      -13-
<PAGE>
 
manner that he reasonably believed to be in, or not opposed to, the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

     SECTION 6.2  Subject to Section 6.3 hereof, the Corporation shall indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
Corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer or employee of the Corporation, or is or was serving
at the request of the Corporation as a director, officer, or employee of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in, or not opposed to,
the best interests of the Corporation; except that no indemnification shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the Corporation unless and only to the extent that
the Court of Chancery or the court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses which the Court of Chancery
or such other court shall deem proper.

     SECTION 6.3  Any indemnification under this Article 6 (unless ordered by a
court) shall be made by the Corporation only as authorized in the specific case
upon a determination that indemnification of the director, officer or employee
is proper in 

                                      -14-
<PAGE>
 
the circumstances because he has met the applicable standard of conduct set
forth in Section 6.1 or Section 6.2 of this Article 6, as the case may be. Such
determination shall be made (i) by the Board of Directors by a majority vote of
a quorum consisting of directors who are not parties to such action, suit or
proceeding, (ii) if such a quorum is not attainable, or, even if attainable, if
a majority vote of a quorum of disinterested directors so directs, by
independent legal counsel in a written opinion or (iii) by the stockholders. To
the extent, however, that a director, officer or employee of the Corporation has
been successful on the merits or otherwise in defense of any action, suit or
proceeding described above, or in defense of any claim, issue or matter therein,
he shall be indemnified against expenses (including attorneys' fees) actually
and reasonably incurred by him in connection therewith, without the necessity of
authorization in the specific case.

     SECTION 6.4  For purposes of any determination under Section 6.3 of this
Article 6, a person shall be deemed to have acted in good faith and in a manner
he reasonably believed to be in, or not opposed to, the best interests of the
Corporation, or, with respect to any criminal action or proceeding, to have had
no reasonable cause to believe his conduct was unlawful, if his action is based
on the records or books of account of the Corporation or another enterprise
(provided that such records or books of account have in each case been prepared
by persons whom the person relying thereon reasonably believes to be
professionally or expertly competent to prepare such records or books of
account), or on information supplied to him by the officers of the Corporation
or another enterprise in the course of their duties, or on the advice of legal
counsel for the Corporation or another enterprise or on information or records

                                      -15-
<PAGE>
 
given or reports made to the Corporation or another enterprise by an independent
certified public accountant or by an appraiser or other expert selected with
reasonable care by the Corporation or another enterprise. The term "another
enterprise" as used in this Section 6.4 shall mean any other corporation or any
partnership, joint venture, trust or other entity of which such person is or was
serving at the request of the Corporation as a director, officer or employee.
The provisions of this Section 6.4 shall not be deemed to be exclusive or to
limit in any way the circumstances in which a person may be deemed to have met
the applicable standard of conduct set forth in Section 6.1 or 6.2 of this
Article 6, as the case may be.

     SECTION 6.5  Notwithstanding any contrary determination in the specific
case under Section 6.3 of this Article 6, and notwithstanding the absence of any
determination thereunder, any director, officer or employee may apply to any
court of competent jurisdiction in the State of Delaware for indemnification to
the extent otherwise permissible under Sections 6.1 and 6.2 of this Article 6.
The basis of such indemnification by a court shall be a determination by such
court that indemnification of the director, officer or employee is proper in the
circumstances because he has met the applicable standards of conduct set forth
in Section 6.1 or 6.2 of this Article 6, as the case may be. Notice of any
application for indemnification pursuant to this Section 6.5 shall be given to
the Corporation promptly upon the filing of such application.

     SECTION 6.6  Expenses incurred in defending or investigating a threatened
or pending action, suit or proceeding may be paid by the Corporation in advance
of the final disposition of such action, suit or proceeding as authorized by the
Board of Directors upon receipt of an undertaking by or on behalf of the
director, officer or

                                      -16-
<PAGE>
 
employee to repay such amount if it shall ultimately be determined that he is
not entitled to be indemnified by the Corporation as authorized in this Article
6.

     SECTION 6.7  The indemnification and advancement of expenses provided by,
or granted pursuant to, the other sections of this Article 6 shall not be deemed
exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any by-law, agreement, contract,
vote of stockholders or disinterested directors or pursuant to the direction
(howsoever embodied) of any court of competent jurisdiction or otherwise, both
as to action in his official capacity and as to action in another capacity while
holding such office, it being the policy of the Corporation that indemnification
of, and advancement of expenses to, the persons specified in Sections 6.1 and
6.2 of this Article 6 shall be made to the fullest extent permitted by law. To
this end, the provisions of this Article 6 shall be deemed to have been amended
for the benefit of such persons effective immediately upon any modification of
the General Corporation Law of the State of Delaware which expands or enlarges
the power or obligation of corporations organized under such law to indemnify,
or advance expenses to, such persons. The provisions of this Article 6 shall not
be deemed to preclude the indemnification of, or advancement of expenses to, any
person who is not specified in Section 6.1 or 6.2 of this Article 6 but whom the
Corporation has the power or obligation to indemnify, or to advance expenses
for, under the provisions of the General Corporation Law of the State of
Delaware or otherwise. The indemnification and advancement of expenses provided
by, or granted pursuant to, this Article 6 shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a director,
officer or employee

                                      -17-
<PAGE>
 
and shall inure to the benefit of the heirs, executors and administrators of
such person.

     SECTION 6.8  The Corporation may purchase and maintain insurance on behalf
of any person who is or was a director, officer or employee of the Corporation,
or is or was serving at the request of the Corporation as a director, officer or
employee of another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against him and incurred by him in any
such capacity, or arising out of his status as such, whether or not the
Corporation would have the power or the obligation to indemnify him against such
liability under the provisions of this Article 6.

     SECTION 6.9  For purposes of this Article 6, references to the
"Corporation" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued, would
have had the power and authority to indemnify its directors, officers and
employees, so that any person who is or was a director, officer or employee of
such constituent corporation, or is or was serving at the request of such
constituent corporation as a director, officer or employee of another
corporation, partnership, joint venture, trust or other enterprise, shall stand
in the same position under the provisions of this Article 6 with respect to the
resulting or surviving corporation as he would have with respect to such
constituent corporation if its separate existence had continued.

                               ARTICLE 7  STOCK

     SECTION 7.1  The certificates representing shares of stock of the
Corporation shall be numbered and shall be entered in the books of the
Corporation as they are issued. Each stockholder shall be entitled to a
certificate exhibiting such stockholder's name and the number of shares held by
such stockholder, which certificate shall be signed by the Chairman of the Board
or the President or any Vice President, and by the Treasurer or the Secretary or
any Assistant Secretary. Any or all of the signatures on such certificate may
be a facsimile. In case any officer, transfer agent or registrar who has signed
or whose facsimile signature has been placed upon a certificate shall have
ceased to be such officer, transfer agent or registrar before such certificate
is issued, such certificate may be issued by the Corporation with the same
effect as if he were such officer, transfer agent or registrar at the date of
issue.

     SECTION 7.2  Transfers of stock shall be made only upon the transfer books
of the Corporation maintained in an office of the Corporation or by transfer
agents designated to transfer shares of the stock of the Corporation, and only
by the person named in the certificate or by his attorney, lawfully constituted
in writing, and upon surrender of the certificate therefor.

     SECTION 7.3  In order that the Corporation may determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors 

                                      -19-
<PAGE>
 
may fix, in advance, a record date, which shall not be more than sixty nor less
than ten days before the date of such meeting nor more than sixty days prior to
any other action. A determination of stockholders of record entitled to notice
of or to vote at a meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the Board of Directors may fix a new record
date for the adjourned meeting.

     SECTION 7.4  The Corporation shall be entitled to treat the holder of
record of any share or shares of stock as the holder in fact thereof and
accordingly shall not be bound to recognize any equitable or other claim to or
interest in such share or shares on the part of any other person, whether or not
it shall have express or other notice thereof, save as expressly provided by the
laws of the State of Delaware.

     SECTION 7.5  The Board of Directors may authorize the issuance of a new
certificate representing shares of stock in place of any certificate previously
issued by the Corporation and alleged to have been lost, stolen or destroyed,
pursuant to such regulations as the Board of Directors may establish concerning
proof or advertisement of such alleged loss, theft or destruction and concerning
the giving of a satisfactory bond or bonds sufficient to indemnify the
Corporation against any claim that may be made against it on account of the
alleged loss, theft or destruction of any such certificate.

     SECTION 7.6  The issue, transfer, conversion and registration of
certificates of stock of the Corporation shall be governed by such other
regulations as the Board of Directors may from time to time establish.

                        ARTICLE 8  PURPOSES AND POWERS

     SECTION 1.   The purpose of the Corporation is to engage in any lawful act
or activity for which corporations may be organized under the General
Corporation Law of the State of Delaware; provided that the Corporation's
activities shall be confined to the maintenance and management of its intangible
investments and the collection and distribution of the income from such
investments or from tangible property physically located outside Delaware, all
as defined in, and in such manner to qualify for exemption from income taxation
under, Section 1902(b)(8) of Title 30 of the Delaware Code, or under the
corresponding provision of any subsequent law; provided further that the
Corporation shall be empowered to conduct such other activities as permitted by
said Section 1902(b)(8) or the corresponding provision of any subsequent law in
such manner to qualify for exemption from income taxation under said Section
1902(b)(8) or the corresponding provision of any subsequent law. For purposes of
this Section "intangible investments" shall include, without limitation,
investments in stocks, bonds, notes and other debt obligations (including debt
obligations of affiliated corporations), patents, patent applications,
trademarks, trade names and similar types of intangible assets.

                               ARTICLE 9  NOTICES

     SECTION 9.1  Whenever notice is required to be given to any director, 
committee member, officer, stockholder, employee or agent, whether pursuant to
law, the Certificate of Incorporation of the Corporation or these By-laws, it
shall not be construed to mean personal notice, but such notice may be given, in
the case of stockholders, in writing, by depositing the same in the mail,
postage prepaid, or by

                                      -21-
<PAGE>
 
overnight carrier addressed to such stockholder at his last known address as the
same appears on the books of the Corporation, and, in the case of directors,
committee members, officers, employees and agents, by telephone, or by mail,
postage prepaid, or by prepaid telegram at his last known address as the same
appears on the books of the Corporation. All notices shall be deemed to be given
when mailed, telegraphed or telephoned.

     SECTION 9.2   Whenever notice is required to be given to any stockholder,
director, committee member, officer, employee or agent, whether pursuant to law,
the Certificate of Incorporation of the Corporation or these By-laws, a written
waiver thereof, signed by the person entitled to notice, whether before or after
the time stated therein, shall be deemed equivalent to notice.  Attendance of a
person at a meeting shall constitute a waiver of notice of such meeting, except
as otherwise provided by law.  Neither the business to be transacted at, nor the
purpose of, any regular or special meeting of the stockholders, directors, or
members of a committee of directors need be specified in any written waiver of
notice unless so required by the Certificate of Incorporation of the Corporation
or by these By-laws.

                           ARTICLE 10  MISCELLANEOUS

     SECTION 10.1  Any officer of the Corporation shall, if required by the
Board of Directors, give the Corporation a bond for the faithful performance of
the duties of his office, and for the restoration to the Corporation of all
corporate books, papers, vouchers, money and property of whatever kind in his
possession or under his control. Such bond shall be for a sum and with such
surety or sureties as the Board of 

                                      -22-
<PAGE>
 
Directors may require.

     SECTION 10.2  The corporate seal shall be in the charge of the Secretary
and shall have inscribed thereon the name of the Corporation and the words

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To James River Paper Company, Inc.
and Radnor Holdings Corporation:
 
  We have audited the accompanying balance sheets of J.R. CUP FOAM CONTAINER
OPERATIONS OF JAMES RIVER PAPER COMPANY, INC. (a Virginia corporation)
(formerly Handi-Kup Foam Container Operations of James River Paper Company,
Inc.), as of December 25, 1994 and December 31, 1995, and the related
statements of operations, changes in owner's investment and cash flows for
each of the three years in the period ended December 31, 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements 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 present fairly,
in all material respects, the financial position of the J.R. Cup Foam
Container Operations of James River Paper Company, Inc. as of December 25,
1994 and December 31, 1995, and the results of its operations for each of the
three years in the period ended December 31, 1995, in conformity with
generally accepted accounting principles.

                     J.R. CUP FOAM CONTAINER OPERATIONS OF
                        JAMES RIVER PAPER COMPANY, INC.
 
                         NOTES TO FINANCIAL STATEMENTS
 
(1) ORGANIZATION AND BASIS OF PRESENTATION:
 
 The Company
 
  As of the dates and for the periods presented, J.R. Cup Foam Container
Operations (the Company) (formerly Handi-Kup Foam Container Operations of
James River Paper Company, Inc.) was an operating unit of James River Paper
Company, Inc. (James River). The Company manufactures and distributes foam
cups, containers and thermoformed lids primarily to national, institutional
and retail customers throughout the U.S.
 
 Basis of Presentation
 
  On January 20, 1996, James River entered into a Joint Venture with WinCup
Holdings, Inc. (WinCup), another foam cup manufacturer, whereby both parties
contributed their fixed assets, leasehold improvements, technology, patents,
trademarks, real property and other noncurrent assets associated with their
foam cup and container and thermoformed lid manufacturing operations and all
inventory, spare parts and other current assets, excluding cash and accounts
receivable, to the Joint Venture.
 
  The Joint Venture is structured as a Delaware limited partnership with
WinCup as the sole general partner and James River as the sole limited
partner. Ownership interests are allocated 55% to WinCup and 45% to James
River.
 
  The financial statements include certain amounts that have been allocated to
the Company by James River. Specifically, these allocations include general
and administrative expenses and accruals for advertising, market survey,
promotion, legal fees and customer performance allowances. Management believes
that the allocation methodologies used to allocate these corporate centrally
managed costs to the Company represent a reasonable basis for allocation.
Included in selling, general and administrative expenses are $3.0 million,
$2.6 million and $2.7 million in customer performance allowances allocated to
the Company by James River for the periods ended December 26, 1993, December
25, 1994 and December 31, 1995, respectively. All other expenses allocated
from James River are included in allocation from James River in the
accompanying statements of operations.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Fiscal Year
 
  The Company's fiscal year includes the 52 or 53 weeks ending on the last
Sunday in December. The year ended December 31, 1995 included 53 weeks while
the years ended December 25, 1994 and December 26, 1993 each included 52
weeks.
 
 Cash
 
  Prior to the date of its acquisition by WinCup, the Company was a
participant in the cash pool of James River. All of the cash of the James
River subsidiaries was deposited into a single account. All cash requirements
of James River and its subsidiaries were then funded out of this cash pool. As
a result, the Company had no cash balances recorded on its books prior to its
acquisition by WinCup.
 
 Inventories, Net
 
  Inventories are stated at the lower of cost (first-in, first-out) or market
and include the cost of materials, labor and manufacturing overhead.
Inventories consist of the following at December 25, 1994 and December 31,
1995:

 Property, Plant and Equipment
 
  Property, plant and equipment is stated at cost, less accumulated
depreciation. Expenditures for improvements that increase the values or extend
the useful life are capitalized and maintenance repair costs are expensed as
incurred. For financial reporting purposes, depreciation is computed using the
straight-line method over the useful lives of the respective assets, which
range from 20 to 45 years for buildings and 5 to 20 years for machinery and
equipment. Leasehold improvements are amortized over the lesser of their
estimated useful lives or the term of the lease using the straight-line
method.
 
 Supplies and Spare Mold Parts
 
  Supplies and spare mold parts include maintenance parts maintained in a
central stores location. When parts are needed at the various manufacturing
facilities, the parts are shipped and expensed in that period.
 
 Accrued Liabilities
 
  The components of accrued liabilities are as follows at December 25, 1994
and December 31, 1995:

</TABLE>
 
 Pension Assets and Post Retirement Benefits Other than Pensions
 
  James River sponsors various contributory and noncontributory pension plans.
Benefits under the plans are primarily based on years of service and
compensation. An allocation of the total James River net pension asset
exclusive of the net minimum liabilities of $123,000 and $70,000 at December
25, 1994 and December 31, 1995, respectively, has been included in other
assets in the accompanying financial statements of the Company.
 
  James River provides certain medical and life insurance benefits to eligible
employees upon retirement. An allocation of the amounts attributable to the
Company's employees of $716,000 and $781,000 at December 25, 1994 and December
31, 1995, respectively, has been included in other long-term liabilities in
the accompanying financial statements.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Fair Value of Financial Instruments
 
  The estimated fair value of financial instruments has been determined by the
Company using the available market information and valuation methodologies.
Considerable judgment is required in estimating fair values. Accordingly, the
estimates may not be indicative of the amounts the Company could realize in a
current market exchange.
 
  The carrying values of accounts receivable, accounts payable and accrued
liabilities approximate fair values due to the short-term maturities of these
financial instruments.
 
(3) COMMITMENTS AND CONTINGENCIES:
 
  The Company leases certain facilities, vehicles and equipment over varying
periods. None of the agreements contain unusual renewal or purchase options.
As of December 31, 1995, future minimum rental payments under noncancelable
operating leases were as follows (in thousands):

  Rent expense totaled $2.2 million, $2.4 million and $2.4 million in 1993,
1994 and 1995, respectively.
 
 Litigation
 
  The Company is involved in various legal actions arising in the normal
course of business. After taking into consideration legal counsel's evaluation
of such actions, management believes that these actions will not have a
significant effect on the Company's financial position or results of
operations.
 
  In July 1996, StyroChem, the Company's primary supplier of expandable
polystyrene beads (EPS) filed suit in the United States District Court for the
Northern District of Texas against James River for breach of a supply contract
between StyroChem and James River. The contract in question required James
River to purchase from StyroChem all of the EPS requirements for its foam
operations through February 1999, provided that the material satisfied certain
product specifications. Because the product supplied by StyroChem did not meet
such specifications, James River ceased purchasing EPS from StyroChem and did
not assign the contract to the Joint Venture in connection with its formation.
The Joint Venture agreed to indemnify James River for certain liabilities
relating to the failure of James River to assign the contract in question to
the Joint Venture and the Joint Venture has assumed the defense of such
litigation, subject to certain reservations of rights. The lawsuit has been
stayed pending the outcome of a proposed acquisition of StyroChem by WinCup,
and management expects the lawsuit will be dismissed with prejudice following
the consummation of the acquisition. Management does not believe the ultimate
outcome of the lawsuit will have a material effect on the Company's financial
position or results of operations.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
(4) RELATED PARTY TRANSACTIONS:
 
  Transactions with other James River locations are reflected as though they
were settled immediately as an addition to or a reduction of James River's
investment and there are no amounts due to or from James River at the end of
any period.
 
(5) INCOME TAXES:
 
  The Company has historically been included in the consolidated federal
income tax return and combined/unitary state income tax returns of James
River. No provision for income taxes has been reflected in the accompanying
financial statements as the Company has historically generated tax losses on a
standalone basis. Deferred income tax assets and liabilities have been
determined at the corporate level and have not been allocated on a standalone
basis. Because the Company is included in the James River consolidated federal
income tax return, net operating loss carryforwards, investment and other tax
credit carryforwards, if any, were utilized by James River. Accordingly, the
Company has no reportable net operating loss or tax credit carryforwards on a
standalone basis.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To SP Acquisition Co.:
 
  We have audited the accompanying consolidated balance sheet of SP
Acquisition Co. (a Delaware Corporation) and subsidiaries as of December 5,
1996 and the related consolidated statements of income, stockholders' equity
and cash flows for the eight month period then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
  We conducted our audit 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 audit provides a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of SP
Acquisition Co. and subsidiaries as of December 5, 1996, and the results of
their operations and cash flows for the eight month period then ended in
conformity with generally accepted accounting principles.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  BUSINESS--SP Acquisition Co. (SPAC) and subsidiaries develop, manufacture
and market a broad line of crystal polystyrene and expandable polystyrene for
sale to manufacturers of foam cups and containers and insulation and packaging
products.
 
  BASIS OF CONSOLIDATION--The accompanying consolidated financial statements
include the accounts of SP Acquisition Co. and its wholly-owned subsidiaries,
StyroChem International, Inc. and StyroChem International, Ltd. (collectively,
the Company). All significant intercompany accounts and transactions have been
eliminated in consolidation.
 
  ACQUISITION--SPAC was incorporated on January 18, 1994 for the sole purpose
of acquiring certain operations of Kimberly-Clark Tissue Company, formerly
known as Scott Paper Company (KCTC). On February 25, 1994, SPAC acquired all
of the outstanding shares of common stock of StyroChem International, Inc. and
StyroChem International, Ltd. from KCTC for an aggregate cash purchase price,
including costs and expenses of approximately $14.5 million, subject to
adjustment for certain contingent consideration. The acquisition was funded by
the proceeds from the issuance of common and preferred stock of SPAC, along
with borrowings under term loans by SPAC and each of the Company's
subsidiaries.
 
  The acquisition was accounted for using the purchase method of accounting
and, accordingly, the purchase price has been allocated to the assets acquired
and liabilities assumed based on their relative fair market values. As of the
acquisition date, assets acquired and liabilities assumed were as follows (in
thousands):

</TABLE>
 
  The excess of the fair value of the net assets acquired was accounted for as
a reduction in the fair value allocated to property and equipment.
 
  FISCAL YEAR--The Company's fiscal year ends on the Saturday nearest March 31
of each year.
 
  UNAUDITED SUMMARY OPERATING RESULTS--Summary operating results of the
Company for the unaudited three month period ended March 30, 1996 are as

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
           FOR THE YEARS ENDED APRIL 1, 1995 AND MARCH 30, 1996 AND
                 THE EIGHT MONTH PERIOD ENDED DECEMBER 5, 1996
 
  CASH AND CASH EQUIVALENTS--For the purposes of reporting cash flows, cash
and cash equivalents includes investments readily convertible to cash with
remaining maturities at date of purchase of three months or less.
 
  FINANCIAL INSTRUMENTS--The Company's financial instruments under Statement
of Financial Accounting Standards No. 107, "Disclosure About Fair Value of
Financial Instruments," include cash and cash equivalents, accounts
receivable, accounts payable and long-term debt. The Company believes that the
carrying amounts of cash and cash equivalents, accounts receivable, accounts
payable and long-term debt to banks are a reasonable estimate of their fair
value because of the short-term maturities of such instruments or, in the case
of long-term debt to banks, because of the floating interest rates on such
long-term debt.
 
  INVENTORIES--Inventories are valued at the lower of cost or market with cost
determined using the average cost method. Inventories consist of finished
goods, work-in-process and raw materials. Finished goods costs include raw
materials, direct labor and indirect production and overhead costs. The
Company provides an allowance for obsolescence based on management's
evaluation of future usefulness and salability of inventory.
 
  PROPERTY, PLANT AND EQUIPMENT--Property, plant and equipment are recorded at
cost. Depreciation is recorded using the straight-line method over the
estimated useful lives of the assets, as follows:

                                                                 ---------------
      <S>                                                        <C>

      Machinery and equipment...................................      3-10
      Furniture and fixtures....................................      5-10
</TABLE>
 
  Expenditures that result in the enhancement of the assets involved are
capitalized and maintenance and repair costs are expensed when incurred. Upon
sale or other disposition, any gain or loss is included in income.
 
  PROPERTY HELD FOR SALE--Land and structures currently being offered for sale
are classified separately from property and equipment.
 
  INCOME TAXES--Federal income taxes have been computed in accordance with
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes," which requires income taxes to be accounted for under the liability
method. Income taxes are provided for the tax effects of transactions reported
in the financial statements and consist of taxes currently due plus deferred
income taxes related primarily to differences between the basis of property,
plant and equipment due to depreciation differences and to the application of
the purchase method of accounting for financial statement purposes but not for
tax purposes, and nondeductible asset and liability reserves for tax purposes.
The deferred tax assets and liabilities represent the future tax return
consequences of those differences, which will either be taxable or deductible
when the assets and liabilities are recovered or settled. Deferred tax assets
are evaluated based on the guidelines for realization and may be reduced by a
valuation allowance.
 
  FOREIGN CURRENCY TRANSLATION--The assets and liabilities of the Company's
Canadian subsidiary, StyroChem International, Ltd., whose functional currency
is other than the U.S. dollar are translated at year-end exchange rates.
Revenue and expense accounts are translated using the weighted average
exchange rate during the periods. Translation gains and losses are not
included in determining net income but are accumulated in a separate component
of stockholders' equity, as is required by Statement of Financial Accounting
Standards No. 52, "Foreign Currency Translation."
 
  RESEARCH AND DEVELOPMENT--Research and development expenses are charged to
income as incurred. Total research and development expenses were approximately
$1.3 million and $1.6 million for the years ended

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
           FOR THE YEARS ENDED APRIL 1, 1995 AND MARCH 30, 1996 AND
                 THE EIGHT MONTH PERIOD ENDED DECEMBER 5, 1996
 
April 1, 1995 and March 30, 1996, respectively, and approximately $1.5 million
for the eight month period ended December 5, 1996.
 
  ACCOUNTING ESTIMATES--The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
  RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS--Statement of Financial Accounting
Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of," requires that long-lived assets and
certain identifiable intangibles to be held and used by an entity be reviewed
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Impairment is evaluated by
comparing future cash flows (undiscounted and without interest charges)
expected to result from the use of the asset and its eventual disposition to
the carrying amount of the asset. The Company adopted this pronouncement
during the eight month period ended December 5, 1996 and the adoption did not
have a material impact on its consolidated financial position or results of
operations.

  The Company's notes payable and long-term debt agreements contain certain
restrictive covenants. These covenants require that the Company meet certain
requirements such as a minimum current ratio, a minimum trailing twelve-months
operating cash flow, a minimum tangible net worth, a minimum fixed charge
coverage ratio, a maximum ratio of indebtedness to tangible net worth and
maximum dividend distributions. The Company was not in compliance with certain
of these covenants at April 1, 1995 and March 30, 1996, but subsequently
obtained a waiver or an amendment for these instances of noncompliance.
 
  Effective August 31, 1996, the bank term note and line of credit agreement
was amended to revise certain covenants and to extend the final maturities to
September 1, 1998. Under the terms of the loan agreements, the Company has the
option to designate the interest rate for borrowings under the loan agreements
using either a prime plus or London Interbank Offering Rate (LIBOR) option.
The interest rate for domestically designated borrowings under the bank term
note and the line of credit was adjusted to prime plus 0.25% and prime,
respectively. LIBOR designated borrowings under the bank term note and line of
credit agreement bear interest at LIBOR plus 2% and LIBOR plus 1.75%,
respectively. In addition, effective November 1996, the commitment fee was
reduced to 0.25% of the unused balance of the line of credit which is payable
quarterly.

  The Company has established a valuation allowance for deferred tax assets of
the Company's Canadian subsidiary. The deferred tax assets represent primarily
the excess of the tax over the book basis of property, plant and equipment.
Because of the past operating losses of this subsidiary, the Company has been
unable to determine that it is more likely than not that the net deferred tax
assets of this subsidiary will be realized.
 
9. MAJOR SUPPLIER
 
  The Company agreed to purchase a minimum of 67% of its styrene monomer used
in production from one supplier. The agreement was for a five year period
ending February 1999, was renewable for successive annual terms, and provided
for purchases at prevailing market-related prices and for favorable payment
terms.
 
  In connection with this agreement, the Company's majority shareholder
granted this supplier an option to purchase 51,000 shares of common stock held
by the shareholder at the fair market value, as defined, of such shares at the
date of exercise. This option, which is exercisable between March 1, 1997 and
February 28, 1999, also requires this supplier to offer to purchase all the
outstanding shares of the Company's common stock at date of exercise.
 
  During the years ended April 1, 1995 and March 30, 1996, the Company's
purchases from this supplier amounted to approximately $41.0 million and $42.8
million, respectively, and the balance payable to this supplier by the Company
as of April 1, 1995 and March 30, 1996 amounted to approximately $8.6 million
and $8.2 million, respectively. During the eight month period ended December
5, 1996, the Company's purchases from this supplier amounted to approximately
$31.3 million. As of December 5, 1996, the balance payable to this supplier
was approximately $13.4 million.
 
10. CONCENTRATION OF CREDIT RISK
 
  Financial instruments that potentially subject the Company to concentrations
of credit risk consist principally of accounts receivable. Generally, the
Company does not require collateral to support customer receivables. The
Company follows established credit inquiry and investigation procedures in an
attempt to minimize credit risk associated with customer receivables. The
Company has one related party customer,

14. STOCKHOLDERS' EQUITY
 
  On February 25, 1994, the Company issued to its preferred stockholders
warrants to allow for the purchase of 25,313 shares (the "Warrant Shares") of
the Company's common stock at an exercise price of $.01 per share. The
warrants are not exercisable until the notes to stockholders (the Notes) are
repaid; however, they become immediately exercisable in full on the Company's
capital reorganization, merger or acquisition of the Company. The Warrant
Shares are subject to adjustment or cancellation upon the occurrence of
certain events; including the repayment of the Notes in advance of their
scheduled maturity. In addition, the terms of the warrants provide for
adjustments to the exercise price as a result of stock splits, dividends or
issuances. During 1995, warrants for 12,500 shares of common stock were
canceled as a result of early repayments or payments of certain of the Notes.
At April 1, 1995, March 30, 1996 and December 5, 1996, warrants for 12,813
shares were outstanding, which expire at March 31, 1999.
 
15. COMMITMENTS AND CONTINGENCIES
 
  SUPPLY AGREEMENT--The Company is committed under a supply agreement to sell
to WinCup Holdings, L.P. all of WinCup's requirements for expandable
polystyrene for certain of its plants at sales prices based on prevailing
market prices for up to 40 million pounds annually, and no less than 75% of
the requirements for those plants in excess of 40 million pounds annually. The
agreement is for an eight-year period ending February 2000, with options for
annual extensions thereafter.

  Rental expense under operating leases for the years ended April 1, 1995 and
March 30, 1996 was approximately $170,000 and $329,000, respectively, and
approximately $263,000 for the eight month period ended December 5, 1996.
 
  OTHER--The Company is involved in various legal proceedings arising in the
normal course of business. Management believes the outcome of these matters
will not materially affect the consolidated financial position or results of
operations of the Company.
 
  Like other chemical manufacturers, the Company's operations are subject to
extensive and rapidly changing federal and state environmental regulations,
including original and renewal permit application proceedings in connection
with its business operations. These environmental laws and regulations may
require the Company to take action in the future to correct the effects of
prior environmental issues at the Company's facilities, if any. In connection
with the Company's acquisition of its business operations from KCTC on
February 25, 1994, as discussed in Note 1, the Company was indemnified by KCTC
as to environmental matters existing prior to the acquisition date. The extent
of loss related to environmental matters depends on a number of factors,
including technological developments and changes in environmental laws, among
others. Based on currently known facts, management believes that any
environmental costs the Company may incur would not have a material adverse
effect on the consolidated financial position or results of operations of the
Company.
 
  The Company participates in a self-insurance program that provides for the
payment of employee health claims. The program provides for specific excess
loss reinsurance for aggregate claims greater than a specified amount for any
one claimant. The Company accrues the estimated liabilities for the ultimate
costs of both reported claims and incurred but not reported claims.
 
16. ACQUISITION BY RADNOR HOLDINGS CORPORATION
 
  On October 30, 1996, the Company's shareholders entered into a definitive
agreement with Radnor Holdings Corporation (Radnor) whereby Radnor agreed to
acquire all the issued and outstanding shares of capital stock of and other
equity interests in the Company for an aggregate purchase price of $31.0
million, subject to satisfactory resolution of environmental matters and
financing and subject to certain adjustments, as defined. The closing of the
acquisition occurred on December 5, 1996.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Neste Oy:
 
  We have audited the accompanying balance sheets of NESTE OY POLYSTYRENE
UPSTREAM BUSINESS IN PORVOO AND KOKEMAKI (an operating unit of the NESTE Oy
Chemicals division) as of December 31, 1995 and 1996, and the related
statements of operations, changes in owner's investment and cash flows for
each of the three years in the period ended December 31, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits 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 present fairly,
in all material respects, the financial position of NESTE OY POLYSTYRENE
UPSTREAM BUSINESS IN PORVOO AND KOKEMAKI as of December 31, 1995 and 1996, and
the results of its operations and its cash flows for each of the three years
in the period ended December 31, 1996, in conformity with generally accepted
accounting principles (see Note 1).

                         NOTES TO FINANCIAL STATEMENTS
               (INCLUDING NOTES APPLICABLE TO UNAUDITED PERIODS)
 
(1) ORGANIZATION AND BASIS OF PRESENTATION:
 
 The Business Unit
 
  Neste Oy (Neste) is an international oil, exploration and production, energy
and chemicals company, which is registered in Espoo, Finland and the shares of
which are quoted on the Helsinki stock exchange. The Neste Oy Polystyrene
Upstream Business in Porvoo and Kokemaki (the Company) has been an operating
unit of the Neste Oy Chemicals division.
 
  The production and sales of the Company consist of polystryrene resins
including expandable polystyrene (EPS), general purpose polystyrene (PS) and
high-impact polystyrene (HIPS). EPS is manufactured in the Porvoo and Kokemaki
plants and PS and HIPS are manufactured in the Porvoo plant. EPS is sold
through Neste Oy Chemicals' European sales network mainly to construction
applications and approximately 30% is sold for packaging uses. Approximately
70% of the PS and HIPS grades are sold in Finland through the Company's
salespeople. The remainder of the PS and HIPS is sold by the Neste Oy
Chemicals sales force.
 
  Neste is establishing a production base in St. Petersburg, Russia where
exploratory marketing efforts have been underway since 1994, using products
exported from Finland. The St. Petersburg plant started operations in the
spring of 1997. These financial statements do not include the St. Petersburg
conversion business.
 
 Basis of Presentation
 
  Neste Oy's records are maintained in accordance with Finnish law and
reporting requirements. These financial statements have been converted from
Finnish generally accepted accounting principles (GAAP) to U.S. GAAP.
 
  The financial statements of the Company include certain amounts that have
been allocated to the Company by Neste Oy. These allocations include general
and administrative expenses incurred at the Porvoo site, but do not include
expenses incurred in the Espoo headquarters. The balance sheet includes a
share of common facilities at the Porvoo site. The definition of common
facilities and the method of allocating them has changed during 1997 such that
these costs are invoiced, not allocated, directly to the Company. Management
believes that the allocation methodologies used to allocate these costs and
corresponding assets to the Company represent a reasonable basis for
allocation. The amounts of the allocations have been shown as separate line
items in the balance sheets and statements of operations in 1994, 1995 and
1996 and are included in selling, general and administrative in the nine month
period ended September 30, 1997.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Fiscal year
 
  The fiscal year of the Company presented in the financial statements is the
calendar year.
 
 Foreign Currency Translation
 
  The assets and liabilities of the Company, whose functional currency is
other than the U.S. dollar, are translated into U.S. dollars at year end
exchange rates. Revenues and expense accounts are translated using the
weighted average exchange rate during the periods indicated. The functional
currency of the Company is the Finnish markka and the exchange rates used were
those quoted by the Bank of Finland. Translation gains and losses are not
included in determining net income but are accumulated in a separate component
of owner's investment, as is required by Statement of Financial Accounting
Standards No. 52, "Foreign Currency Translation."

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 Cash
 
  The Company is an operating unit of the Neste Oy Chemicals division, and
participates in the cash pool of Neste Oy. All cash requirements of the
Company have been funded out of this cash pool. As a result, the entity has no
cash balances recorded on its books.
 
 Revenue Recognition
 
  Revenue is recognized when goods are shipped. Sales are recorded gross
before cash and other discounts, which are deducted from the value of sales,
when the customer fulfills the terms of trade agreed upon.
 
 Research and Development
 
  Research and development expenses are charged to operations as incurred.
Total research and development expenses were approximately $859,000,
$1,233,000, $1,206,000, $885,000 and $861,000 for the years ended December 31,
1994, 1995 and 1996 and the nine month periods ended September 30, 1996 and
1997, respectively.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with U.S. GAAP
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of financial statements and the reported amounts of
revenues and expenses during the reported period. Actual results could differ
from those estimates.
 
 Fair Value of Financial Instruments
 
  The fair value of financial instruments, including accounts receivable and
accounts payable, approximate their recorded values due primarily to the
short-term nature of their maturities.
 
(3) ACCOUNTS RECEIVABLE
 
  Accounts receivable include the following balances due from affiliated
companies:

recorded using the straight-line method over the useful lives of the
respective assets, which range from 20 to 40 years for buildings, 5 to 20
years for machinery and equipment and 5 to 10 years for other property and
equipment.
 
  The share of common facilities allocated from Neste has been shown as a
separate line item, net of accumulated depreciation, in the balance sheets. In
addition to an allocated share of common facilities it includes spare parts
stored in a central stores location, but apportioned to the Company in the
Neste Oy stock records. The amount of spare parts at December 31, 1995 was
$565,000, at December 31, 1996 was $502,000, and at September 30, 1997 was
$419,000. Spare parts are expensed in the period they are needed and shipped

(7) PENSION COSTS
 
  The pensions of the Company personnel are covered by the Joint Pension
Foundation of Neste Corporation (the Foundation) in accordance with the local
laws and practices. The Foundation has been able to offer pension services at
lower annual fees than the market prices of pension insurance companies. The
compulsory deficit of the foundation is immaterial but has been provided for
in the accounts of Neste Oy. Under Finnish GAAP the future salary increases
have not been taken into account when calculating the pension liability. U.S.
GAAP calculations have been prepared only for that part of pension liability
that exceeds the normal pension liability stipulated by law. The calculations
are at the level of total Neste Corporation only, and show that at December
31, 1996 the local method had resulted in a somewhat higher pension liability
and somewhat higher annual pension cost than the U.S. GAAP method.
 
(8) INCOME TAXES
 
  The Company, having legally been part of Neste Oy, has been included in the
tax return of Neste Oy. The tax in the statements of operations has been
calculated by applying the general company tax rate of 28% to the income
before income taxes. No possible tax losses, accelerated depreciation or other
similar effects, which usually have been considered at the level of Neste Oy
only, have been reflected in the calculations. Accordingly no deferred tax
assets or liabilities have been recorded. All taxes are paid by the parent
company.
 
(9) COMMITMENTS AND CONTINGENCIES
 
  The Company is a party to various legal actions arising in the ordinary
course of its business. The liability, if any, associated with these matters
will not have a material adverse effect upon financial condition, results of
operations or cash flows of the Company.
 
  The Company is also subject to environmental regulations, including rules
relating to air and water pollution and the storage and disposal of chemicals
and waste. The Company believes it complies in all material respects with
applicable laws.
 
  It has been Neste Oy's policy to not make use of leased assets except for
minor office equipment.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Isora Oy:
  We have audited the accompanying balance sheets of ISORA OY (a Finnish Joint
Stock company) as of December 31, 1995 and 1996, and the related statements of
operations, changes in stockholder's equity and cash flows for each of the
three years in the period ended December 31, 1996. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits 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 present fairly,
in all material respects, the financial position of ISORA OY as of December
31, 1995 and 1996, and the results of its operations and its cash flows for
each of the three years in the period ended December 31, 1996, in conformity
with generally accepted accounting principles (see Note 1).

                         NOTES TO FINANCIAL STATEMENTS
               (INCLUDING NOTES APPLICABLE TO UNAUDITED PERIODS)
 
(1) ORGANIZATION AND BASIS OF PRESENTATION:
 
 The Business Unit
 
  Isora Oy (the Company) is a Finnish Joint Stock company 100% owned by Neste
Oy.
 
  Isora has three production sites--Nurmijarvi, Vammala and Pietarsaari.
Nurmijarvi is an almost fully automated site for standard insulation products.
Vammala produces standard as well as special products. Pietarsaari, located on
the northwest coast, covers the northern region. In addition to its EPS
conversion business, Isora also produces and markets patented EPS sandwich
elements for a broad range of construction applications. Sales are carried out
through Isora's sales organization located at the three sites.
 
  Neste is establishing a production base in St. Petersburg, Russia where
exploratory marketing efforts have been underway since 1994, using products
exported from Finland. The plant started operations in spring 1997. These
statements do not include any part of the St. Petersburg conversion business.
 
 Basis of Presentation
 
  Isora Oy's records are maintained in accordance with Finnish law and
reporting requirements. These financial statements have been converted from
Finnish generally accepted accounting principles (GAAP) to U.S. GAAP.
 
  The following adjustments have been made to Finnish GAAP amounts to comply
with U.S. GAAP requirements:
 
  . Voluntary provisions (difference between fiscal depreciation and the
    planned depreciation) have been transferred to stockholder's equity.
    Deferred tax at 28% has been deduced from the difference and added to
    long-term liabilities. The change of deferred tax is included in the
    statements of operations (provision for income taxes). The Company has
    accumulated tax losses from fiscal years 1992 and 1994, which can be
    deducted from future taxable profits. Deferred tax on accumulated tax
    losses has not been calculated as the effect on income of 1994 is not
    material.
 
  . Obligatory provisions have been classified as long term liabilities.
 
  . In 1994 Neste Oy paid a group contribution of $305,000 to Isora Oy. In
    these statements the amount has been reflected as a capital contribution,
    so that it has no effect on the income of 1994.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Fiscal year
 
  The fiscal year of the Company presented in the financial statements is the
calendar year.
 
 Foreign Currency Translation
 
  The assets and liabilities of the Company, whose functional currency is
other than the U.S. dollar, are translated into U.S. dollars at year end
exchange rates. Revenues and expense accounts are translated using the
weighted average exchange rate during the periods. The functional currency of
the Company is the Finnish markka and the exchange rates used were those
quoted by the Bank of Finland. Translation gains and losses are not included
in determining net income but are accumulated in a separate component of
owner's investment, as is required by Statement of Financial Accounting
Standards No. 52, "Foreign Currency Translation."

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 Revenue Recognition
 
  Revenue is recognized when goods are shipped. Sales are recorded gross
before cash and other discounts, which are deducted from the value of sales,
when the customer fulfils the terms of trade agreed upon.
 
Use of Estimates
 
  The preparation of financial statements in conformity with U.S. GAAP
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of financial statements and the reported amounts of
revenues and expenses during the reported period. Actual results could differ
from those estimates.
 
 Fair Value of Financial Instruments
 
  The fair value of financial instruments, including accounts receivables and
accounts payable, approximate their recorded values due primarily to the
short-term nature of their maturities.
 
(3) INVENTORIES
 
  Inventories are stated at the lower of cost (first-in, first-out) or market
and consist of the following:

(8) PENSION COSTS
 
  The pensions of the personnel have been covered by the Joint Pension
Foundation of Neste Corporation in line with the local laws and practices. The
foundation has been able to offer pension services at lower annual fees than
the market prices of pension insurance companies. The compulsory deficit of
the foundation, which is immaterial, has been provided for in the accounts of
the company. In Finnish GAAP the future salary increases have not been taken
into account when calculating the pension liability. U.S. GAAP calculations
have been prepared only for that part of pension liability that exceeds the
normal pension liability stipulated by law. The calculations are at the level
of total Neste Corporation only, and show, that at December 31, 1996 the local
method had resulted in a somewhat higher pension liability and somewhat higher
annual pension cost than the U.S. GAAP method.
 
(9) INCOME TAXES
 
  The tax in the statements of operations has been calculated by applying the
general company tax rate of 28% to the income before taxes (according to
Finnish GAAP). Deferred taxes on the differences between the fiscal and
planned depreciation has been added.
 
(10) COMMITMENTS AND CONTINGENCIES
 
  The Company is a party to various legal actions arising in the ordinary
course of its business. The liability, if any, associated with these matters
will not have a material adverse effect upon financial condition, results of
operations or cash flows of the Company.
 
  The Company is also subject to environmental regulations, including rules
relating to air and water pollution and the storage and disposal of chemicals
and waste. The Company believes it complies in all material respects with
applicable laws.

however be transferred to a third party without the consent of the lessor. The
Pietarsaari production facilities have been rented from a third party at an
annual rent of $65,000. The rental period ends 12th of April 2000, but notice
can be given by both parties any time upon six months notice. The contract

party. The contract cannot be transferred to a third party without the consent
of the lessor.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Neste Cellplast AB:
 
  We have audited the accompanying balance sheet of NESTE CELLPLAST AB (a
Swedish Corporation and subsidiary of Neste Sverige AB) as of December 31,
1996, and the related statements of operations, changes in stockholders'
equity and cash flows for the year ended December 31, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
  We conducted our audit 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 present fairly,
in all material respects, the financial position of NESTE CELLPLAST AB as of
December 31, 1996, and the results of its operations and its cash flows for
the year ended December 31, 1996, in conformity with generally accepted
accounting principles (see Note 2).
 
  The financial statements of Neste Cellplast AB for the two years ended
December 31, 1994 and 1995 were audited by other auditors whose reports dated
February 17, 1995 and February 21, 1996, respectively, expressed unqualified
opinions on these statements. The opinion of such auditors, however, does not
cover the restatement of those financial statements as described in Note 2.
 
  We have also audited the adjustments described in Note 2 that were applied
to restate the December 31, 1994 and December 31, 1995 financial statements.
In our opinion, such adjustments are appropriate and have been properly
applied.

                         NOTES TO FINANCIAL STATEMENTS
 
               (INCLUDING NOTES APPLICABLE TO UNAUDITED PERIODS)
 
(1) ORGANIZATION
 
 The Company
 
  Neste Cellplast AB (the Company), a Swedish company, is owned by Neste
Sverige AB (91%) and Gullfiber AB (9%). Neste Sverige AB is a wholly owned
subsidiary of the Finnish oil-chemistry and energy company, Neste Oy. The
Company carries on thermisol manufacturing for insulation purposes in the
building and packaging industry. The Company has two manufacturing plants, one
in Norrtalje, and one in Vargarda. The Company's headquarters are located in
Norrtalje.
 
 Intercompany transaction
 
  For 1995 and 1996 91% and 89%, respectively, of total purchases were made
from other group companies, and 1% and 0%, respectively, of total sales were
made to group companies.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of presentation
 
  The Company's records are maintained in accordance with Swedish laws and
reporting requirements. These financial statements have been prepared in
accordance with United States generally accepted accounting principles ("U.S.
GAAP") and have been translated into U.S. dollars.
 
  For Swedish statutory reporting purposes, operating expenses in the
statement of operations include cost of goods sold, distribution cost and
selling, general and administration costs. For U.S. GAAP purposes these costs
have been separated.
 
 Foreign currency translation
 
  The functional currency for the Company's operations is Swedish krona. The
translation from Swedish krona to U.S. dollars is performed for the balance
sheet accounts using the exchange rates in effect at the balance sheet date
and for revenue and expense accounts using a weighted average exchange rate
during the period. Translation gains and losses are not included in
determining net income but are accumulated in a separate component of
stockholders' equity, as is required by Statement of Financial Accounting
Standards No. 52, "Foreign Currency Translation."
 
 Contributions to Neste Sverige AB
 
  The Company has given group contribution to Neste Sverige AB during each of
the three years ended December 31, 1994, 1995 and 1996. Group contributions
are principally made to transfer taxable income from one group entity with the
objective of reducing the group's total current tax expenses. These
contributions lead to a taxable income for the recipient and a taxable expense
for the donor. The Company's annual current tax expense has therefore been
impacted by the group contributions. Since the contributions are permanent
differences for tax purposes, no deferred tax accounting related to group
contribution has been made.
 
  For Swedish statutory reporting purposes, group contributions are accounted
for as an appropriation in the statement of operations. This accounting
methodology is utilized primarily to obtain an agreement between a company's
financial statement income and taxable income. Group contributions are thus
not related to a company's operations. For U.S. GAAP purposes, group
contributions provided have been treated as a transfer from stockholders'
equity.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Cash
 
  Cash is deposited on a group account held by the Swedish parent company
Neste Sverige AB. The Company has access to these accounts. For Swedish
statutory purposes these liquid funds are disclosed as a short-term receivable
from the parent company. For U.S. GAAP purposes the item is restated to cash.
 
 Revenue Recognition
 
  Revenue is recognized when goods are shipped.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with U.S. GAAP
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of financial statements and the reported amounts of
revenues and expenses during the reported period. Actual results could differ
from those estimates.
 
 Fair Value of Financial Instruments
 
  The fair value of financial instruments is determined by reference to
various market data and other valuation techniques, as appropriate. Unless
otherwise disclosed, the fair value of financial instruments, including
accounts receivable and accounts payable, approximate their recorded values
due primarily to the short-term nature of their maturities.
 
(3) INVENTORY
 
  Inventories are valued at the lower of cost (first-in, first-out) or market.
Provision for obsolescence has been calculated based on review of individual
items. Inventories at December 31, 1995 and 1996, and for the nine month
period ended September 30, 1997 consist of the following items:

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
(5) PROVISION FOR PENSION LIABILITIES
 
  Providing for future pension liabilities, two main systems are used in
Sweden. One where actuarially computed premiums are currently paid to an
independent pension insurance company, and the other where an independent body
computes the actuarial liability for unfunded pensions which a company has to
include among long-term liabilities (the book reserve method).
 
  When a company uses the method by paying premiums to an insurance company
there is no remaining risk or cost to the company for benefits earned to date
once the premium is paid. It is only benefits financed by the book reserve
method that has to be actuarially valued according to FAS 87.
 
  The Company is paying a fixed premium to a Swedish independent insurance
company, SPP. The Company has therefore no pension liability to provide for
and no restatement is to be made according to FAS 87.
 
(6) INCOME TAXES
 
  Deferred income taxes are provided under the asset and liability method.
This method requires recognition of deferred tax liabilities and assets for
the expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this period, deferred income taxes
are determined based on the difference between the financial statement and tax
basis of assets and liabilities using enacted tax rates in effect for the year
in which the differences are expected to reverse. Valuation allowances are
established when necessary to reduce deferred tax assets to the amounts
expected to be realized. Income tax expense consists of the Company's current
liability for income taxes and the change in the Company's deferred tax assets
and liabilities.
 
  The provision for income taxes varies from the amount of income tax
determined by applying the applicable domestic statutory tax rate to pre-tax
income as a result of the following:

(7) COMMITMENTS AND CONTINGENCIES
 
 Patent dispute with Sundolitt AB
 
  The Company is involved in a patent dispute with Sundolitt AB, a Swedish
competitor. In 1991, Sundolitt commenced a patent infringement for the product
"Makribbdack". In 1995, the Swedish Patent and Registration Office accorded
another patent for the product to Sundolitt AB. In November 1995, Sundolitt AB
claimed damages of $110,000. The Company filed an objection towards the patent
to the Swedish Patent and Registration Office in June 1997. The dispute is
expected to be settled in 1997. If the Company loses the dispute, they are to
pay $110,000 in damages to Sundolitt AB.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The Company is also subject to environmental regulations, including rules
relating to air and water pollution and the storage and disposal of chemicals
and waste. The Company believes it complies in all material respects with
applicable laws.
 
(8) EMPLOYEE BENEFIT PLAN:
 
  The Company has a profit sharing plan, which covers all employees. The
Company will pay the employees a total annual bonus amounting to 10% of income
after depreciation. The profit sharing plan exists on a voluntary basis and
the management is free to abolish the plan from one year to another. The board
of directors has decided that a bonus will be paid to the employees according
to the plan in 1997. The bonus amounted to $82,000, $29,000 and $38,000 in
1996, 1995 and 1994, respectively. The amount for 1997 has not yet been
decided upon.
 
(9) RESTRICTIONS ON RETAINED EARNINGS
 
  Retained earnings available for dividends are based upon statutory financial
statements. Under the provisions of the Swedish Companies Act a legal reserve
must be established in an amount equal to 20% of the share capital. This
reserve is established by appropriating 10% of the statutory net income each
year until the prescribed amount has been appropriated. The legal reserve may
be used to absorb deficit, but usually may not be distributed as dividends.
 
  Retained earnings available for dividends were $905,000 at December 31,
1996.
 
(10) SUBSEQUENT EVENTS:
 
  On October 15, 1997, Neste Oy, Isora Oy, Neste Cellplast AB and Neste
Thermisol A/S sold certain EPS, PS and HIPS assets in Finland, Sweden and
Denmark, which include the assets of the Company, to StyroChem Finland Oy,
ThermiSol Finland Oy, ThermiSol Sweden AB and ThermiSol Denmark ApS and Radnor
Holdings Corporation as parent and guarantor.
 
  On October 15, 1997, the minority interest of Gullfiber AB was acquired by
Neste Sverige AB.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Neste Thermisol A/S:
 
  We have audited the accompanying balance sheets of NESTE THERMISOL A/S as of
December 31, 1995 and 1996, and the related statements of operations, changes
in shareholder's equity and cash flows for each of the three years in the
period ended December 31, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits 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 present fairly,
in all material respects, the financial position of NESTE Thermisol A/S as of
December 31, 1995 and 1996, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1996, in
conformity with generally accepted accounting principles (see Note 1).
