ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.
 
  On October 15, 1997, Radnor Holdings Corporation (the "Company"), through
certain newly-formed foreign subsidiaries of the Company (StyroChem Finland
Oy, ThermiSol Finland Oy, ThermiSol Sweden AB and ThermiSol Denmark ApS
(collectively, the "Subsidiaries")) acquired substantially all of the tangible
and intangible assets and long-term investments relating to the polystyrene
production and conversion operations of Neste Oy. The acquired assets
included, without limitation, real property, machinery and equipment,
intellectual property rights, permits and licenses, books and records,
contract rights, inventories and receivables. Following the acquisition, the
assets acquired by the Company and the Subsidiaries will continue to be
utilized for polystyrene production and conversion operations. The parties
made the purchase and sale pursuant to a Sale of Assets Agreement dated as of
September 17, 1997, among Neste Oy, Isora Oy, Neste Cellplast AB and Neste
Thermisol A/S and the Subsidiaries and the Company. Except with respect to
certain post-closing contractual arrangements described below, there was and
is no material relationship between any of the sellers and any of the buyers,
including the Company. The cash consideration for the acquired assets was
213.0 million Finnish markkas ($40.8 million as of the date of closing) plus
the value of the net working capital, which included accounts receivable,
inventory, trade accounts payable and accrued liabilities. The net working
capital was estimated to be 60.0 million Finnish markkas ($11.5 million as of
the date of closing), of which 16.5 million Finnish markkas were placed in an
escrow account at closing and 43.5 million Finnish markkas were paid to Neste
Oy at closing. The purchase price will be adjusted on a markka for markka
basis following an audit of net working capital to the extent that the net
working capital as of closing was greater or less than 60.0 million Finnish
markkas. The Company also obtained an option, pursuant to a letter agreement,
to acquire certain assets relating to conversion operations located in Russia
for a price of 2.0 million Finnish markkas, which the Company anticipates
exercising and closing in 1998. The purchase price was based on negotiations
with Neste Oy. Proceeds from the offering of $60.0 million of the Company's
Series B Senior Notes due 2003, issued pursuant to exemptions under the
Securities Act of 1933, as amended, were utilized to pay the cash
consideration.
 
  In connection with the closing of the acquisition, the Company entered into
certain other arrangements with Neste Oy, including: (i) a Land Lease
Agreement; (ii) a Utilities Supply Agreement; (iii) a Neste Service Agreement;
(iv) a Sales and Marketing Agreement and (v) a Personnel Agreement. The Land
Lease Agreement relates to the land on which the principal expandable
polystyrene manufacturing facility in Porvoo, Finland is located and extends
for a period of 30 years for a nominal rent, with an option for the Company to
extend the lease or acquire the leased property following the initial term of
the lease. Through the Utilities Supply Agreement, which extends for a ten-
year term and thereafter continues unless 24 months' prior written notice of
termination is provided by one of the parties, the Company purchases
electricity, nitrogen, steam, drinking water and salt-free water from Neste
Oy. Pursuant to the Neste Service Agreement, Neste Oy provides certain site
services at the Porvoo industrial complex to the Company. The agreement
initially extends for a period of one year and thereafter continues for
additional one-year periods, with specific services subject to termination
upon written notice provided by either party in accordance with the agreement.
The Sales and Marketing Agreement pertains to the employment by the Company of
certain polystyrene products sales persons and brokerage services to be
provided by affiliates of Neste Oy in certain European countries. This
agreement also grants the Company an option to maintain offices and utilize
certain office services at five sales offices of affiliates of Neste Oy
throughout Europe and Russia. The Personnel Agreement separately relates to
the transfer of certain of Neste Oy's employees to the Company.

                   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 polystyrene 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 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 six month
period ended June 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, $624,000 and $575,000 for the years ended December 31,
1994, 1995 and 1996 and the six month periods ended June 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:

(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.

(10) SUBSEQUENT EVENT

to satisfactory resolution of financing, with StyroChem Finland Oy, Thermisol
Finland Oy, Thermisol Sweden AB and Thermisol Denmark ApS (the Purchasers) and

                   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 the 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:

(4) PROPERTY PLANT AND EQUIPMENT
 
  Property, plant and equipment are recorded at cost. Expenditures for
improvements that increase the values or extend the useful life are

of the respective assets, which is 15 years for machinery and equipment and 5
years for other capitalized expenditures.

(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.

                   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 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 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.

(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
 
 Shareholder agreement with Gullfiber AB
 
  Neste Sverige AB has reached an agreement to acquire the minority interest
of Gullfiber AB.
 
 Patent dispute with Sundolitt AB
 
  The Company is involved in a patent dispute with Sundolitt AB, a Swedish
competitor. In 1991, Sundolitt commented 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
claimed damages of $110,000. The Company has 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.
 
  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.
 
(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 EVENT:
 
  On September 17, 1997, Neste Oy, Isora Oy, Neste Cellplast AB and Neste
Thermisol A/S (the Sellers) entered into a sale of assets agreement, subject
to satisfactory resolution of financing, with StyroChem Finland Oy, Thermisol
Finland Oy, Thermisol Sweden AB and Thermisol Denmark ApS (the Purchasers) and
Radnor Holdings Corporation as parent and guarantor concerning the sale and
purchase of certain EPS, PS and HIPS assets in Finland, Sweden and Denmark,
which includes the assets of the Company.

                   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).

(1) ORGANIZATION AND BASIS OF PRESENTATION:
 
 The Business Unit
 
  Neste Thermisol A/S (the Company) is owned by the Finnish concern Neste Oy,
who has activities within chemistry, gas and natural gas. The company is
registered in Denmark.
 
  The Company produces and markets insulation material made of polystyrene for
the Danish and German construction activities, and has considerable market
shares within floor- and roof insulation.
 
 Basis of Presentation
 
  The Company's records are maintained in accordance with Danish law and
reporting requirements. These financial statements have been converted from
Danish GAAP to U.S. GAAP.
 
(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. 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."
 
 Cash
 
  The Company is an operating unit of Neste Oy, and participates in the cash
pool of Neste Oy. All cash requirements of the Company have been funded out of
this cash pool.
 
 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.
 
 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

 RADNOR HOLDINGS CORPORATION AND SUBSIDIARIES PRO FORMA CONSOLIDATED FINANCIAL
                                     DATA
 
  The following pro forma consolidated financial data have been prepared based

Corporation, the J.R. Foam Container Operations of James River Paper Company,
Inc., SP Acquisition Co. and Subsidiaries, the Neste Oy Polystyrene Upstream
Business in Porvoo and Kokemaki, Isora Oy, Neste Cellplast AB, and Neste
Thermisol A/S, including the notes thereto. The pro forma consolidated
statements of operations reflect the acquisition of the U.S. foam cup and
container operations of James River Paper Company, Inc. (the "J.R. Cup
Acquisition"), the acquisition of SP Acquisition Co. and its subsidiaries (the
"StyroChem Acquisition") and the sale of $100 million of Radnor Holdings
Corporation Senior Notes due 2003 on December 5, 1996 (the "Prior Notes") as
well as the acquisition (the "StyroChem Europe Acquisition") of substantially
all of the polystyrene production and conversion operations of Neste Oy
("StyroChem Europe") and the sale of $60 million of Radnor Holdings
Corporation Series B Senior Notes due 2003 on October 15, 1997 (the "Notes")
as though they had occurred on December 30, 1995. The J.R. Cup Acquisition,
the StyroChem Acquisition and the StyroChem Europe Acquisition are referred to
collectively as the "Acquisitions." The pro forma consolidated balance sheet
reflects the StyroChem Europe Acquisition and the sale of the Notes as though
they had occurred on June 27, 1997. The pro forma consolidated financial data
are based on the assumptions and adjustments described in the accompanying
notes and do not purport to present the results of operations and financial
position of Radnor Holdings Corporation and its Subsidiaries as if the
Acquisitions and the sale of the Prior Notes and the Notes had actually
occurred on such dates, nor are they necessarily indicative of the results of
operations that may be achieved in the future.

    EBITDA is not a measure of financial performance under Generally Accepted
    Accounting Principles ( "GAAP") and should not be considered as an
    alternative either to net income as an indicator of the Company's
    operating performance or to cash flows as a measure of the Company's
    liquidity.

           (iv)  all obligations and liabilities of any kind whatsoever related
                 to, arising out of or under or in respect of the conduct or
                 operation of the BUSINESS or the ownership or utilisation of
                 the ASSETS after the CLOSING;

           (v)   all obligations and liabilities of any kind whatsoever related
                 to, arising out of or under or in respect of the acts or
                 omissions of any of the PURCHASERS and/or their successors and
                 assigns with respect to the BUSINESS and/or the ASSETS after
                 the CLOSING; and

           (vi)  accrued supplemental pension plan liabilities, by means of a
                 transfer by Nesteen Elakesaatio (Neste Pension Fund, herein
                 referred to as "NPF") of the funds of NPF (the approximate
                 amount of which as of June 30, 1997 was FIM 10,500,000)
                 covering the liabilities of NPF calculated according to the
                 Finnish pension legislation and regulations accrued prior to
                 the CLOSING DATE in respect of employees of Neste Oy,
                 transferring to the employment of the PURCHASERS in connection
                 with the TRANSFER, entitled to the benefits of "Category A"
                 (the "Supplemental Pension Liabilities") as defined in the

                 insurance company selected by the PURCHASERS for the purpose of
                 continuing the coverage of the Supplemental Pension Liabilities
                 in respect of such employees after the CLOSING DATE;

           (collectively, the "ASSUMED LIABILITIES").

       c)  Neste Oy shall retain, bear, discharge and perform (i) all CLAIMS

           ASSETS or the BUSINESS other than the ASSUMED LIABILITIES; and (iii)
           all CLAIMS described in Article 4.3 a).


4.4    Nature of the TRANSFER

       Although the SELLERS believe that the ASSETS, when taken in combination
       with the SELLERS' employees to be transferred to the PURCHASERS and other
       items to be acquired by the PURCHASERS together with the procured
       services and utilities, should be sufficient for the PURCHASERS to
       continue the BUSINESS, the SELLERS make no representation or warranty
       that the ASSETS or the SELLERS' use or operation thereof will yield any
       given economic, financial, profit or business result or structure or will
       result in Purchasers Polystyrene Products' business having any given
       standing or position in the Polystyrene Products' markets or industry.
       Although the provisions of Article 8 do not contain any representation
       and warranty from the SELLERS that expressly states that the ASSETS or
       the SELLERS' use or operation thereof will yield any given economic,
       financial, profit or business result or structure or will result in the
       PURCHASERS' Polystyrene Products' business having any given standing or
       position in the Polystyrene Products' markets or industry, the provisions
       of this Article 4.4 shall not prejudice or otherwise affect the
       provisions of Article 8.


4.5    Manner of implementing the TRANSFER

       Unless otherwise agreed between the SELLERS and the PURCHASERS, the
       TRANSFER shall be implemented between the PARTIES as follows:

5. PURCHASE PRICE AND RELATED MATTERS

5.1    PURCHASE PRICE and Payment

       a)  The total purchase price for the ASSETS shall be (i)
           twohundredthirteenmillion Finnish Markkas (FIM 213,000,000), and (ii)
           the value of the NET WORKING CAPITAL as of the CLOSING DATE, as
           determined in accordance with paragraph (b) below (collectively
           referred to as the "PURCHASE PRICE"). As of the CLOSING DATE, the
           PURCHASE PRICE based on SELLERS' estimate of the value of the NET
           WORKING CAPITAL of sixtymillion Finnish Markkas (FIM 60,000,000) as
           of the CLOSING DATE, the details of which are attached hereto as
           Schedule 12, (the "ESTIMATED NET WORKING CAPITAL VALUE"), is expected
           -----------
           to be twohundredseventythreemillion Finnish Markkas (FIM 273,000,000)
           (the "ESTIMATED PURCHASE PRICE"). Schedule 16 contains a complete and
                                             -----------
           accurate list of all ACCOUNTS RECEIVABLE, which list sets forth the
           aging of such ACCOUNTS RECEIVABLE. At the CLOSING, the PURCHASERS
           shall pay to the SELLERS the ESTIMATED PURCHASE PRICE less 16,500,000
           Finnish Markkas (the "ESCROWED AMOUNT") in immediately available
           funds by bank wire transfer to such account(s) and institution(s) as
           may be designated by the SELLERS in a notice to PURCHASERS at least
           seven (7) days prior to the CLOSING. In addition, at the CLOSING the
           PURCHASERS shall pay the ESCROWED AMOUNT to Merita Bank Ltd. or to
           such other institution as shall be agreed among the SELLERS and the
           PURCHASERS under terms reasonably satisfactory to the SELLERS and the
           PURCHASERS pursuant to which the ESCROWED AMOUNT shall be disposed of
           in the manner set forth in Article 5.1 b) (ii) below.

       b)  (i)  For purposes of determining the ESTIMATED NET WORKING CAPITAL
                and the NET WORKING CAPITAL as of the CLOSING DATE: (i) NET
                WORKING CAPITAL shall mean the sum of the trade accounts
                receivable (which each represent valid obligations due from
                third parties and arising from sales actually made or services
                actually performed in the ordinary course of business by one of
                the SELLERS) (the "ACCOUNTS RECEIVABLE") and inventories, less
                the sum of trade accounts payable and other current liabilities
                incurred in the conduct of the BUSINESS, (ii) cash shall be
                excluded, (iii) ACCOUNTS RECEIVABLE, trade accounts payable and
                other current liabilities shall be valued markka for markka,
                (iv) raw materials and other inventory shall be valued at the
                lower of cost or market on a first-in-first-out basis, and (v)
                all working capital accounts shall be valued in accordance with
                generally accepted accounting principles of the respective
                country concerned and on a consistent basis with prior periods.

           (ii) The SELLERS and the PURCHASERS shall jointly engage Arthur
                Andersen Oy, a firm of chartered accountants, to determine the
                NET WORKING CAPITAL as of the CLOSING DATE, requiring such
                accountants to deliver to the SELLERS and the PURCHASERS within
                sixty (60) days after the CLOSING DATE a statement showing the
                calculation of the NET WORKING CAPITAL as of the CLOSING DATE
                (the "CLOSING STATEMENT"). The SELLERS and the PURCHASERS shall
                each bear 50% of the fees of such accountants. If, within thirty
                (30) days following delivery of the CLOSING STATEMENT to the
                SELLERS and the PURCHASERS, the SELLERS have not given the
                PURCHASERS written notice of any objection to the CLOSING
                STATEMENT and/or the PURCHASERS have not given to the SELLERS
                written notice of any objection to the CLOSING
<PAGE>
 
                                                                              16


                STATEMENT (which notice in each case, must contain a
                statement of the basis of the objection), then the NET WORKING
                CAPITAL reflected in the CLOSING STATEMENT shall be deemed to be
                the NET WORKING CAPITAL of the BUSINESS as of the CLOSING DATE.
                If the SELLERS or the PURCHASERS give such notice of objection
                within the allotted time period and the parties are unable to
                resolve the subject of such objection within thirty (30) days
                after such notice, then the issues in dispute will be submitted
                to Price Waterhouse, London (the "ACCOUNTANTS"), for resolution
                with instructions to the ACCOUNTANTS to resolve such dispute
                within forty-five (45) days. If issues in dispute are submitted
                to the ACCOUNTANTS for resolution, (i) each party will furnish
                to the ACCOUNTANTS such work papers and other documents and
                information relating to the disputed issues as the ACCOUNTANTS
                may request and are available to that party (or its independent
                public accountants) and each party will be afforded the
                opportunity to present to the ACCOUNTANTS any material relating
                to the determination and to discuss the determination with the
                ACCOUNTANTS; (ii) the determination by the ACCOUNTANTS, as set
                forth in a notice delivered to both PARTIES by the ACCOUNTANTS,
                will be binding and conclusive on the PARTIES; and (iii) the
                PURCHASERS and the SELLERS will each bear fifty percent (50%) of
                the fees of the ACCOUNTANTS for such determination.

                If a CLOSING STATEMENT which neither the SELLERS nor the
                PURCHASERS have objected to in accordance with the provisions
                set out above confirms, or if after resolution of all the
                disputes it is determined by the ACCOUNTANTS that the value of
                the NET WORKING CAPITAL as of the CLOSING DATE is more than the
                ESTIMATED NET WORKING CAPITAL, the ESCROWED AMOUNT shall be
                immediately paid to the SELLERS, and in addition the PURCHASERS
                shall immediately pay to the SELLERS in immediately available
                funds the amount of such difference, together with interest on
                such amounts at the prevailing HELIBOR interest rate at 12:00
                noon on the CLOSING DATE for three month deposits (the "INTEREST
                RATE").

                If a CLOSING STATEMENT which neither the SELLERS nor the
                PURCHASERS have objected to in accordance with the provisions
                set out above confirms, or if after resolution of all the
                disputes it is determined by the ACCOUNTANTS that the value of
                the NET WORKING CAPITAL as of the CLOSING DATE is less than the
                ESTIMATED WORKING CAPITAL by more than the ESCROWED AMOUNT, then
                the ESCROWED AMOUNT shall be immediately paid to the PURCHASERS
                and the SELLERS shall immediately pay to the PURCHASERS in
                immediately available funds the amount of such difference,
                together with interest on such amounts at the INTEREST RATE.

                If a CLOSING STATEMENT which neither the SELLERS nor the
                PURCHASERS have objected to in accordance with the provisions
                set out above confirms, or if after resolution of all the
                disputes it is determined by the ACCOUNTANTS that the value of
                the NET WORKING CAPITAL as of the CLOSING DATE is less than the
                ESTIMATED NET WORKING CAPITAL but by an amount (the
                "DIFFERENCE") not exceeding the ESCROWED AMOUNT, that portion of
                the ESCROWED AMOUNT representing the difference between the
                ESCROWED AMOUNT and the DIFFERENCE shall be immediately paid to
                the SELLERS, and the PURCHASERS shall pay to the SELLERS
                interest on such portion at the
<PAGE>
 
                                                                              17


                INTEREST RATE, and the remaining portion of the ESCROWED
                AMOUNT shall be paid to the PURCHASERS.

                Any interest earned on the ESCROWED AMOUNT shall be paid to the
                PURCHASERS at such time as the ESCROWED AMOUNT is paid in
                accordance with the foregoing provisions.


5.2    Allocation of the PURCHASE PRICE

       The PURCHASE PRICE shall be allocated among the ASSETS as stated in
       Schedule 9.
       ----------

5.3    Costs of the TRANSFER

       The PURCHASERS shall pay all taxes, fees and expenses related to the
       TRANSFER, including all notarial fees and expenses, registration taxes,
       fees connected with license transfers, filing fees and recordation
       expenses, but excluding (i) the expenses to be borne by the SELLERS
       referred to in Article 5.5 hereof, (ii) income taxes, capital gains taxes
       and other taxes related to the income of the SELLERS, and (iii) such
       taxes, fees and expenses that by law or regulation, or by virtue of a
       contract between the SELLERS (or any of them) and a third party, must be
       paid by the SELLERS.


5.4    Apportionments and Prepaid Items

       a)  Costs of a recurrent nature which are incurred in respect of the
           ASSETS and all of which are specified in Schedule 15 and which relate
           to the period both prior to and subsequent to the CLOSING, shall be
           apportioned between the PARTIES according to the number of days in
           the period covered by such items which occurred respectively prior to
           and subsequent to the CLOSING DATE. The PARTIES shall determine the
           respective apportioned amounts and the necessary payments to be made
           between the PARTIES with respect thereto and such payments shall be
           made at the CLOSING or as soon as practicable after the CLOSING.

       b)  In the event that the PARTIES by a date not later than thirty (30)
           days after the CLOSING DATE do not reach an agreement in respect of
           the apportioned amounts and the necessary payments to be made by each
           PARTY in accordance with paragraph a) above, the SELLERS and the
           PURCHASERS shall jointly engage Arthur Andersen Oy, a firm of
           chartered accountants, to determine such amounts and payments to be
           made, requiring such accountants to deliver to the SELLERS and the
           PURCHASERS within thirty (30) days after their engagement a statement
           showing such amounts and payments to be made by each PARTY.

       c)  If, within thirty (30) days following delivery of the statement
           referred to in paragraph b) above to the SELLERS and the PURCHASERS,
           the SELLERS have not given to the PURCHASERS written objection to
           such statement, and/or the PURCHASERS have not given to the SELLERS
           written objection to such statement, then the apportioned amounts and
           the payments specified in such statement shall be deemed accepted by
           all the PARTIES and the payments specified in such statement shall be
           paid within seven (7) days of the date when such period of thirty
           (30) days expired. If the SELLERS or the

                                                                              18


           PURCHASERS give such notice of objection within the allotted time
           period and the parties are unable to resolve the subject of the
           objection within thirty (30) days after such notice, then the issues
           at dispute will be submitted to the ACCOUNTANTS, for resolution with
           instructions to the ACCOUNTANTS to resolve such dispute within forty-
           five (45) days. If the issues in dispute are submitted to the
           ACCOUNTANTS for resolution, (i) each PARTY will furnish to the
           ACCOUNTANTS such work papers and other documents and information
           relating to the disputed issues as the ACCOUNTANTS may request and
           are available to that PARTY (or its independent public accountants)
           and each PARTY will be afforded the opportunity to present the
           ACCOUNTANTS any material relating to the determination and discuss
           the determination with the ACCOUNTANTS; and (ii) the determination by
           the ACCOUNTANTS set forth in a notice delivered to the PARTIES
           involved in such dispute will be binding and conclusive on such
           PARTIES.

       d)  The SELLERS and the PURCHASERS shall each bear 50% of the fees of the
           accountants referred to in paragraph b) above and of the fees of the
           ACCOUNTANTS referred to in paragraph c) above.

       attorneys, consultants, financial advisors, tax advisors and their
       respective employees, servants and agents) incurred by it or on its
       behalf, in connection with the TRANSFER. For the avoidance of doubt,

       1997, or on such other date as the PARTIES may mutually agree, at the
       offices of Neste Oy, Finland. The PARTIES shall act diligently to cause
       the conditions set forth in Articles 6.2 and 6.3 to be satisfied as soon
       as practicable after the date hereof. However, the CLOSING may be held at
       such other time, date and/or place as may be agreed upon by the PARTIES.
       If, at any time, any of the PURCHASERS or the SELLERS has reason to
       believe that the CLOSING cannot be held on October 15, 1997, it shall
       promptly notify the other PARTIES and the PARTIES shall attempt in good
       faith to agree upon and take such actions as may be reasonably necessary
       to conduct the CLOSING as soon as practicable as the then circumstances
       will permit.

       The date of the commencement of the CLOSING is referred to herein as the
       "CLOSING DATE". The CLOSING, when completed, shall be effective as of

       If the CLOSING does not occur by October 31, 1997, each PARTY shall have
       the right to terminate this AGREEMENT forthwith by a written notice to
       the other PARTIES. Termination pursuant to this Article 6.1 shall not
       give the PURCHASERS the right to make claims or demands against the
       SELLERS nor the SELLERS the right to make claims or demands against the
       PURCHASERS, unless the CLOSING does not occur by reason of a PARTY's
       failure to cause the CLOSING to occur by such date.


6.2    Conditions to the PURCHASERS' obligations to complete the CLOSING

       a)  The obligation of the PURCHASERS to complete the CLOSING shall be
           subject to the fulfilment, in a manner satisfactory to the

           following conditions:

           1)   Each of the PURCHASERS having acquired all governmental and
                other consents and approvals which are required for each
                PURCHASER to execute and deliver this AGREEMENT and the CLOSING
                DOCUMENTS and to effectuate its part of the TRANSFER;

           2)   There not having occurred, between the date hereof and the
                CLOSING DATE, any act or omission by any of the SELLERS that
                would constitute a breach of any of the material obligations of
                any of the SELLERS under this AGREEMENT;

           3)   The representations and warranties made by the SELLERS in this
                AGREEMENT and the CLOSING DOCUMENTS being true and correct in
                all material respects (except with respect to (i)
                representations and warranties which are themselves qualified by
                materiality which shall be true and correct in accordance with

              Neste Oy shall so assume such defence and/or intervene, in any
              discussion, suit, action or proceeding which could reasonably be

                     which is below FIM 50,000 and unless the aggregate amount
                     of liability under such Article exceeds FIM 1,500,000 in
                     the aggregate (not including individual claims the
                     indemnifiable amount of which is below FIM 50,000),
                     provided that once the aggregate amount of liability under
                     such Article exceeds FIM 1,500,000 (not including
                     individual claims the indemnifiable amount of which is
                     below FIM 50,000), the PARTY claiming indemnification shall
                     be entitled to the whole amount of all such liability (not
                     including individual claims the indemnifiable amount of
                     which is below FIM 50,000) and not merely the excess.
                     Notwithstanding the foregoing, the limitations set out in
                     paragraphs a) and b) of this Article 7.3 shall not apply to
                     any breach of the representations and warranties set out in
                     Article 8.14 (Taxes), the obligations of the SELLERS
                     pursuant to Article 11.2 (Accounts Receivable), or the
                     obligations of any PARTY under Articles 5.1 b) (ii)
                     (Purchase Price and Payment), 5.3 (Costs of the Transfer),
                     5.4 (Apportionments and Prepaid Items), and 5.5 (Expenses
                     of the Parties).

              b)     Any claims for damages under Articles 7.1 (i), 7.1 (ii), or
                     7.1 (iii) or 7.2 (i) or 7.2 (ii) may not exceed an amount
                     equivalent to 75% of the PURCHASE PRICE in the aggregate.
                     The provisions in this Article 7 shall be the exclusive
                     remedy (other than proceedings for injunctive or other
                     equitable relief) of a PARTY for any breach of any of the
                     representations, warranties, covenants or agreements of the
                     other PARTY in this AGREEMENT.

              c)     Each PARTY shall endeavour to take all reasonable measures
                     within its control to mitigate damages arising in
                     connection with any breach of representation or warranty
                     under this Agreement. For the avoidance of doubt, any costs
                     incurred by a PARTY in connection with the mitigation of
                     damages caused by the breach of representations and
                     warranties by any other PARTY shall be included in the
                     CLAIMS to be indemnified under Article 7.1 (ii) or 7.2
                     (ii), as the case may be.

              d)     Notwithstanding any other provisions in this AGREEMENT, the
                     SELLERS shall not be liable to the PURCHASERS, and the
                     PURCHASERS shall not be liable to the SELLERS, for any

                     event that would otherwise give the right to seek

7.4           Right to Information about Liabilities

              Each PARTY shall furnish from time to time the other PARTY with
              such information as such other PARTY may reasonably request with
              respect to the satisfaction and discharge of all acts, duties,
              liabilities and obligations that are assumed or retained by or are
              to be performed or satisfied by or on behalf of such PARTY
              hereunder or in connection herewith (including the items referred
              to in Articles 4.3 (a) - (c) hereof, as the case may be).


7.5           Notice and Assistance

              a)     If, after the CLOSING, any PARTY becomes aware of any
                     matter or event, or becomes a participant in any suit,
                     action or proceeding (whether legal, administrative,
                     arbitration or other) which could reasonably be expected to
                     result in a CLAIM indemnified against hereunder, then such
                     PARTY shall promptly notify the other PARTY thereof. Upon
                     the reasonable request of the PARTY giving such notice (the

                     with the Requestor, at the Requestor's expense, in any
                     legal action or defense undertaken by or against the
                     Requestor relating to such event, suit, action and/or
                     proceeding and in which such other PARTY does not have an
                     adverse interest to that of the Requestor.

              b)     The PURCHASERS must notify Neste Oy, as to each claim for
                     indemnification under Article 7.2(ii) other than
                     indemnification based on Articles 8.14 or 8.25, within
                     eighteen (18) months from the CLOSING DATE.

              c)     The PURCHASERS must notify Neste Oy, as to each claim for

                     (Environmental, Health and Safety Matters), within five (5)
                     years from the CLOSING DATE.

              d)     The PURCHASERS must notify Neste Oy, as to each claim for

                     (18) months from the CLOSING DATE


7.6           For the avoidance of doubt, to the extent a CLAIM can be asserted
              both as a breach of representations and warranties of the SELLERS
              hereunder, and as a liability to be retained or assumed by the
              SELLERS in accordance with Article 4.3, such CLAIM shall be
              asserted as a liability to be retained or assumed by the SELLERS
              in accordance with Article 4.3.


8. REPRESENTATIONS AND WARRANTIES OF THE SELLERS

                     absolute and complete bar to the exercise of all rights,
                     remedies and causes of action of every kind which the

              effectuation by the SELLERS of their part of the TRANSFER results
              in or constitutes or will result in or will constitute a default
              or an event that, with notice or lapse of time or both, would be a
              default, breach or violation of (i) the articles of association or

              contract, agreement or instrument or any judgement, decree or

              The SELLERS' use and operation of the ASSETS and their conduct of

              ASSETS free and clear of all ENCUMBRANCES except the PERMITTED
              ENCUMBRANCES and when the TRANSFER shall have been completed, the
              SELLERS will have conveyed to the PURCHASERS valid and legal title
              and possession to the ASSETS free and clear of all ENCUMBRANCES
              except the PERMITTED ENCUMBRANCES.


8.9           Completeness and condition of the ASSETS

              The ASSETS comprise all the assets used by SELLERS in the

              sound, in good operating condition and repair, and adequate for
              the uses to which they are being put, and are not in need of
              maintenance or repairs except for ordinary, routine maintenance
              and repairs that are not material in nature or cost. The ASSETS
              are in good operating condition and repair and are sufficient for

              substantially the same manner as conducted prior to the CLOSING
              excepting ordinary wear and tear.

                     the consummation of the TRANSFER will, directly or
                     indirectly (with or without notice or lapse of time) cause
                     the PURCHASERS or the BUSINESS to become subject to, or to
                     become liable for the payment of, any TAX (except those
                     TAXES for which the PURCHASERS are responsible under
                     Article 5.3).


8.15          Contracts

              The SELLERS are not a party to any material contract or agreement

8.16          Absence of breaches and defaults

              None of the SELLERS is in material default or material breach or

              investigation, capable of being declared in material default or
              material breach of any of the CONTRACTS, and none of the SELLERS
              is in default or breach under any of the CONTRACTS which default
              or breach constitutes a reason under which any other party under
              such CONTRACT is entitled to terminate the CONTRACT or exercise
              other remedies under the written terms of such CONTRACT, and all
              of the CONTRACTS are now in good standing and each of the SELLERS
              is entitled to all benefits under the CONTRACTS to which such
              SELLER is a party.


8.17          Agreements with labour unions/employee associations

              None of the SELLERS is bound by or has made any collective

              to or conducted negotiations in respect of material commitments
              with any labour union or employee association except those
              specified in Schedule 19.

8.18          Absence of other agreements for sale of BUSINESS

              The SELLERS have not since June 10, 1997 entered into any
              agreements with any party other than the PURCHASERS relating to
              the sale or other disposition of all or a substantial part of the
              BUSINESS.


8.19          SELLERS' right to intellectual property

              The INTELLECTUAL PROPERTY ASSETS are all those necessary for the
              operation of the BUSINESS as currently conducted. The SELLERS have
              the full right, title, and interest to the INTELLECTUAL PROPERTY
              being transferred hereunder and full right, title and interest
              thereto is being transferred to the PURCHASERS with the exception
              of the office application computer software referred to in Article
              11.7.


8.20          Completeness of RECORDS

              The RECORDS are true, complete and not misleading in any material
              respects.


8.21          Valid PERMITS

              The PERMITS constitute the material licenses, permits and
              consents, and the licences, permits and consents the absence of
              which would cause the PURCHASERS or any of their directors,
              officers or employees to be subject to fines or other criminal or
              administrative sanctions, which are required for the operation of
              the BUSINESS, including the operation of the PLANTS, provided that
              the foregoing shall not apply to licences, permits or consents
              relating to the EXCLUDED ASSETS. To the actual knowledge of the
              SELLERS after reasonable investigation, there is no pending or
              threatened material breach or material default by any party under
              any of the PERMITS or any breach or default that would cause the
              PURCHASERS or any of their directors, officers or employees to be
              subject to fines or other criminal or administrative sanctions.
              The PERMITS are in full force and effect. Except as set forth in
              Schedule 4, no SELLER is or will be required to give any notice to
              ----------
              or obtain any consent from any person with respect to the PERMITS
              in connection with the execution and delivery of this AGREEMENT or
              the consummation or performance of the TRANSFER. To the actual
              knowledge of SELLERS after reasonable investigation, the PERMITS
              are readily transferable to PURCHASERS or capable of being
              re-issued in the name of the PURCHASERS prior to or immediately
              after the CLOSING DATE without unreasonable efforts on the part of
              SELLERS or PURCHASERS.


8.22          Absence of non-competition restrictions

              The BUSINESS is not subject to restrictions, contractual or, to
              the actual knowledge of the SELLERS, after reasonable
              investigation, otherwise, preventing the owner and operator of the
              BUSINESS to compete in the fields of business in which the
              BUSINESS is presently conducted.

8.23          Labour relations

              There have been no strikes or work stoppages by employees of the
              BUSINESS nor any other labour grievances at any of the facilities
              comprising the BUSINESS, including any of the PLANTS, at any time

              -----------


8.24          Accuracy

              No representation or warranty of the SELLERS in this AGREEMENT or
              any Schedule hereto or other documents executed in connection
              herewith nor any certificate furnished or to be furnished by the
              SELLERS to PURCHASERS pursuant hereto or in connection with the
              transactions contemplated hereby, when taken as a whole with any
              information contained in this AGREEMENT or any such Schedule,
              document or certificate, contains any untrue or misleading
              statement of any material fact or omits to state any material fact
              necessary to make the statements contained therein, under the
              circumstances in which they are made, not misleading in any
              material respect.

                     of such allegation; and

                     period specified in Article 7.5 (e) above, shall be an
                     absolute and complete bar to the exercise of all rights,
                     remedies and causes of action of every kind which the

                     warranty.

              Subject to the subparagraphs (i) - (ii) above, the PURCHASERS
              represent and warrant to the SELLERS the following, as of the date

                     information of the SELLERS which comprise the purchased
                     ASSETS, and have had the opportunity to ask questions of,

                     officers of the SELLERS regarding the ASSETS and the
                     BUSINESS.

              b)     (i)  If any RADNOR Specified Person (as hereinafter
                          defined) has or obtains actual knowledge at any time
                          on or prior to four (4) BUSINESS DAYS prior to the

                          respect any representation and warranty made by the
                          SELLERS in this AGREEMENT, the PURCHASERS will, as

                          the use of their best reasonable efforts, to remedy
                          such inaccuracy, and if the PURCHASERS nevertheless
                          decide to complete the CLOSING, the inaccuracy shall
                          be deemed to have been waived and the PURCHASERS will
                          not be entitled to indemnification in respect of such
                          inaccuracy.

              and good will with suppliers, customers, landlords, creditors,

11.2          Accounts Receivable

              a)     From the date of the CLOSING until a date 180 days after
                     the CLOSING DATE (the "COLLECTION PERIOD"), the PURCHASERS
                     shall scrupulously and consistent with customary collection
                     practices for the BUSINESS, attempt to collect all ACCOUNTS
                     RECEIVABLE. The SELLERS shall when needed cooperate and
                     consult with the PURCHASERS in such collection measures. It
                     is expressly agreed that the PURCHASERS shall not be
                     required to use any method of collection different from
                     that customarily used by the BUSINESS in the collection of
                     accounts. It is further agreed that the PURCHASERS shall
                     have no obligation to institute legal proceedings to
                     collect all or any portion of the ACCOUNTS RECEIVABLE.

              b)     During the COLLECTION PERIOD, the PURCHASERS shall not have
                     the right to settle, release or otherwise compromise any
                     ACCOUNTS RECEIVABLE without the prior written consent of
                     the SELLERS, which consent shall not be unreasonably
                     withheld, unless such settlement, release or compromise
                     results in the immediate payment to the PURCHASERS in full
                     of the amount outstanding on such ACCOUNT RECEIVABLE.

              c)     During the COLLECTION PERIOD, the PURCHASERS shall provide
                     the SELLERS upon reasonable request of the SELLERS with a
                     status report as to the collection of the ACCOUNTS
                     RECEIVABLE, which report shall include reasonable details
                     regarding the collection efforts by the PURCHASERS and the
                     debtor's response.

              d)     To the extent any debtor on any of the ACCOUNTS RECEIVABLE
                     is also a debtor to the PURCHASERS for debts incurred after
                     the CLOSING DATE, a remittance by such debtor shall be
                     deemed to be on account of the earliest unpaid invoice for
                     such debtor. Notwithstanding the foregoing, if any such
                     debtor disputes a specific ACCOUNT RECEIVABLE attributable
                     to such debtor (based on a claim of product defect,
                     non-delivery, double payment or other legitimate reason for
                     nonpayment) and requests that the remittance be credited
                     against one or more debts incurred by such debtor after the
                     CLOSING DATE, the remittance shall be credited in
                     accordance with the debtor's instructions.

              e)     Upon the expiration of the COLLECTION PERIOD, Neste Oy
                     shall purchase from the PURCHASERS, for full face amount
                     together with interest thereon accrued thereon at the
                     INTEREST RATE, all of the ACCOUNTS RECEIVABLE which the
                     PURCHASERS have not been able to collect in full in
                     accordance with the provisions of this Article 11.2, as
                     shown on a statement issued by the PURCHASERS and including
                     the details referred to in paragraph c) above with respect
                     to the date when the COLLECTION PERIOD expires. Such
                     payment shall be made to an account specified by the
                     PURCHASERS within ten (10) days after the expiration of the
                     COLLECTION PERIOD.

              f)     Upon payment of the purchase price referred to in paragraph
                     e) above, the PURCHASERS shall assign the ACCOUNTS
                     RECEIVABLE to be purchased under such paragraph e) to the
                     SELLERS.

              after the date hereof the PURCHASERS shall hold and cause each
              person receiving from or on behalf of the PURCHASERS any part of

              connection herewith (such person being a "Recipient"), including

              Sterns, and the respective parents, subsidiaries, affiliates,
              directors, members, partners, officers, employees, servants and
              agents of the PURCHASERS and such law and investment banking firms
              to hold such information in strict confidence and not disclose the
              same to any person without the prior written approval of the
              SELLERS in each instance except and unless (i) such disclosure is
              compelled by law or a valid court order, provided all reasonable
              efforts (e.g. protective orders) have been made to preserve the
              confidentiality or trade secret status of such information, (ii)
              the part of such information to be disclosed has become generally
              available to the public other than as a result of a disclosure by
              the PURCHASERS, or (iii) the part of such information to be
              disclosed has become available to the PURCHASERS on a
              non-confidential basis from a source other than the SELLERS,
              unless the PURCHASERS knew or reasonably should have known, that
              such source owed to the SELLERS and/or any of its respective
              subsidiaries or affiliates a confidentiality or non-disclosure
              obligation relating to such information and in all instances, the
              PURCHASERS shall make reasonable inquiries to ascertain whether
              such source owes or owed such an obligation. If the TRANSFER is
              not effectuated, then the PURCHASERS shall cause all originals and
              all copies of all tangible items (including books, records,
              documents, blueprints and drawings) possessed by or on behalf of
              the PURCHASERS or a Recipient and containing such information to
              be promptly delivered to the SELLERS, provided however that the
              foregoing provisions shall not create any obligation for the
              PURCHASERS to return to the SELLERS the Letter of Intent dated 10
              July 1997 between Neste Oy and RADNOR (the "Letter of Intent") nor
              any document containing professional advice received by RADNOR in

11.4          Secrecy obligations of the SELLERS

              If the TRANSFER is effectuated, the SELLERS covenant that, for a
              period of five (5) years after the date hereof the SELLERS shall
              hold in strict confidence and not disclose to any third person
              information or trade secrets relating to or belonging to the
              BUSINESS unless (i) such disclosure is compelled by law or a valid
              court order, provided all reasonable efforts (e.g. protective
              orders) have been made to preserve the confidentiality or trade
              secret status of such information, or (ii) the part of such
              information to be disclosed has become generally available to the
              public other than as a result of a disclosure by the SELLERS.


11.5          Post-CLOSING Identification

              As soon as may be practicable after the effectuation of the
              TRANSFER, and in any event no later than six (6) months from the
              CLOSING DATE, the PURCHASERS shall take all steps necessary to
              print over, mask with an adhesive label, or otherwise obliterate
              all references to the trade name "NESTE" on all existing
              literature, forms and stationary supplied to third parties and on
              all labels and shipping containers. Except as provided in this
              Article 11.5 no other right or license to use the name "NESTE" is

              a letter to be sent by the SELLERS and the PURCHASERS jointly to
              the customers of the BUSINESS as soon as practicable after the
              signing of this AGREEMENT by the PARTIES.


11.7          Office application software

              If the transfer of any office application software (e.g. Microsoft
              Windows) included in the INTELLECTUAL PROPERTY requires the
              consent or approval of any third party to the transfer thereof to
              the PURCHASERS or is subject to other restrictions on transfer set
              forth in any license agreement or otherwise, then the SELLERS
              shall use their reasonable best efforts to obtain such consent,
              approval or waiver of such restriction on transfer (but without
              the obligation to expend any money in connection therewith),
              provided, that if the payment of any money is needed to effectuate
              such transfer then the SELLERS shall notify the PURCHASERS thereof
              and shall give the PURCHASERS the right to make such payment to
              effectuate such transfer.


11.8          Transition support services

              If after the date hereof the PURCHASERS determine that they will
              reasonably require the SELLERS to continue to provide any
              administrative, data systems or other support services that are
              currently being provided by the SELLERS to the BUSINESS, such
              services being in addition to the services to be provided under
              the terms of the SERVICE AGREEMENTS, then the PURCHASERS shall
              notify the SELLERS accordingly and the SELLERS shall provide such
              services for the period reasonably required by the PURCHASERS on
              the following basis:

                                                                              41

              a)     during the period of the first thirty (30) days (the
                     "Initial Period") after the PURCHASERS notify the SELLERS
                     in accordance with the foregoing with respect to a specific
                     service, such service shall be provided free of charge,
                     other than the SELLERS' reasonable out-of-pocket expenses
                     paid to third parties which shall be reimbursed by the
                     PURCHASERS to the SELLERS;

              b)     during the period of the first two (2) months after the
                     expiration of the Initial Period, such service shall be
                     provided at the SELLERS' direct cost;

              c)     during the period of the third (3rd), fourth (4th) and
                     fifth (5th) month after the expiration of the Initial
                     Period, such service shall be provided at the SELLERS'
                     direct cost plus 15%;

              d)     notwithstanding anything to the contrary, in no event shall
                     the services described in this Article 11.8 be provided for
                     longer than a six (6) month period of transition
                     immediately after the CLOSING; and

              e)     such support services shall be provided on such other terms
                     as are currently applicable to the provision of such
                     services to the BUSINESS.


11.9          Corrections to Inaccuracies or Omissions in certain Schedules

              At any time not later than the fourth (4th) BUSINESS DAY prior to
              the CLOSING DATE, the SELLERS may provide to the PURCHASERS one or
              more notices (if any) setting forth corrections in respect of
              inaccuracies or omissions in any Schedule to this Agreement (other
              than Schedules 9, 11, 12 and 18 - 22), and the relevant Schedule
              shall thereby be deemed to be amended to incorporate such
              correction; provided, however, that no such notice shall qualify
              or amend any of the representations or warranties of SELLERS under
              Article 8.


12. OBLIGATION TO USE THE PLANTS AND DISPOSAL OF THE ASSETS

12.1          The PURCHASERS will endeavour to use the PLANTS after the CLOSING

                                 of the five (5) year term of this Article 13.4,
                                 then the provisions of this sub-paragraph e) i)
                                 shall thereupon be void; and

                     (ii) NCT Holland B.V. and its subsidiaries, branches and
                          group of companies ("NCT") may purchase, sell and
                          trade the PRODUCTS; provided, however, that NCT will
                          not sell any of the PRODUCTS in Finland, Sweden,
                          Norway, Denmark, Poland, Latvia, Estonia or Lithuania
                          at any time during the five (5) year term of this

              f)     The term "CUSTOMERS" shall mean the PURCHASERS' customers
                     as of the date of this AGREEMENT and the PURCHASERS' actual

                     Article 13.4.

              g)     After the CLOSING DATE, the SELLERS shall cease using the
                     business names, trademarks, tradenames, designs and models
                     listed in Schedule 3, and shall not use confusingly similar
                               ----------
                     trademarks, tradenames, designs and models in connection
                     with their business or otherwise; provided, however, that
                     nothing herein shall restrict or limit in any way the
                     SELLERS' right to use the name "Neste" and the Isora Oy
                     logo or the shape thereof (but not the name "Isora").

              h)     The non-compete obligation set forth in paragraph a) above
                     does not apply if Neste Oy or its AFFILIATE acquires a
                     business in a larger acquisition, where the volume of the
                     POLYSTYRENE PRODUCTS and/or CONVERTED PRODUCTS does not
                     amount to more than 20% of the total sales volume acquired,
                     provided that Neste Oy or its AFFILIATE divests such
                     POLYSTYRENE PRODUCTS and/or CONVERTED PRODUCTS business to
                     a party other than an AFFILIATE of Neste Oy or to an entity
                     50% of the capital stock or voting rights of which are
                     owned or controlled by Neste Oy within a period of nine (9)
                     months from the date of such acquisition, and prior to any
                     divestment of such business shall first offer to RADNOR the
                     opportunity to acquire such business.

              i)     In the event that Neste Oy or any of its AFFILIATES or
                     divisions is acquired by or merged with a company that
                     operates a business which competes with the BUSINESS, the
                     non-compete obligation set forth in paragraph a) shall not
                     apply to the resulting merged, acquired or acquiring
                     company.

              j)     Neste Oy and its AFFILIATES may acquire and hold directly
                     or indirectly up to 10% of the shares of a publicly traded
                     or floated company as a financial investment even though
                     activities of such company compete with the BUSINESS.

              k)     Without affecting the provisions in Article 13.9, the
                     PARTIES hereby agree that should the duration or the
                     geographic scope of the obligations of the SELLERS as
                     defined in paragraph a) above be prohibited or not
                     enforceable in any jurisdiction, then such obligations
                     shall remain in force to the fullest extent permitted by
                     law.


13.5          Successors and Assigns

              a)     This AGREEMENT shall be binding upon and shall inure to the
                     benefit of the PARTIES and their respective successors and
                     assigns, but neither PARTY may, directly or indirectly,
                     assign or transfer this AGREEMENT or any right, obligation
                     or interest herein in whole or in part without the prior
                     written consent of the other PARTY in each instance.
                     Regardless of any such written consent which may be
                     granted, no assignment or transfer shall be binding and
                     valid until and unless the assignee or transferee shall
                     have assumed in writing all of the duties and obligations
                     of the assignor or transferor hereunder and furthermore the
                     assignor or transferor shall remain primarily liable
                     hereunder. Any attempted assignment or transfer in
                     violation of this Article 13.5 shall be null and void.

              b)     Notwithstanding the foregoing, any PARTY may assign its
                     rights and obligations under this AGREEMENT to an AFFILIATE
                     of such PARTY, provided that no assignment or transfer
                     shall be binding and valid until and unless the assignee or
                     transferee shall have assumed in writing all of the duties
                     and obligations of the assignor or transferor hereunder and
                     furthermore the assignor or transferor shall remain
                     primarily liable hereunder and provided further that Neste
                     Oy may not assign its obligations under Article 7 of this
                     AGREEMENT to an AFFILIATE, and RADNOR may not assign its
                     obligations under Article 14 of this AGREEMENT to an
                     AFFILIATE, and no such assignment by Neste Oy and RADNOR of
                     such respective obligations shall be permitted.


13.6          Discharge, Amendments, etc.

              (i)    This AGREEMENT may not be released, discharged, abandoned,
                     changed, amended or modified in any manner in any instance,
                     except by a written document signed by the PARTY sought to
                     be charged thereby.

              (ii)   The failure of any PARTY to enforce at any time any of the
                     provisions of this AGREEMENT shall in no way be construed
                     to be a waiver of any such provision, nor in any way to
                     affect the validity of this AGREEMENT or any part thereof
                     or the right of any party thereafter to enforce each and
                     every such provision.

              (iii)  No waiver of any provision (whether in whole or in part) of
                     this AGREEMENT in any instance shall be held to be a waiver
                     of any other similar or dissimilar provision, part or
                     instance.

              (iv)   The exercise by any PARTY of a right to terminate this
                     AGREEMENT in itself shall not create or give rise to any
                     obligation by such PARTY to the other PARTY as a result of
                     such termination.


13.7          Governing Law

              This AGREEMENT shall be governed by the law of Finland without
              giving effect to any principle of law which would result in the
              application of the law of some other jurisdiction.


13.8          Resolution of Disputes

              All disputes arising in connection with this AGREEMENT shall be
              finally settled under the Rules of Conciliation and Arbitration of
              the International Chamber of Commerce by three arbitrators
              appointed in accordance with the said Rules, provided, however,
              that the SELLERS may appoint jointly only one arbitrator and,
              correspondingly, the PURCHASERS and RADNOR may jointly appoint
              only one arbitrator. The arbitration shall be held in London,
              England, unless otherwise agreed among the PARTIES, and shall be
              conducted in the English language. Each PARTY shall use its best
              reasonable efforts to take all action which it reasonably can take
              or cause to be taken to facilitate the conduct of the arbitration
              and the rendering of the arbitral award at the earliest possible
              date.


13.9          Severability

              Any provision of this AGREEMENT which is prohibited or
              unenforceable in any jurisdiction, shall be ineffective to the
              extent of such prohibition or unenforceability without affecting,
              impairing or invalidating the remaining provisions hereof or the
              enforceability of such provision in such jurisdiction or any other
              jurisdiction.


13.10         Counterparts

              This AGREEMENT may be executed in one or more counterparts, each
              of which shall be deemed to be an original and all of which shall
              constitute one and the same instrument.


13.11         This AGREEMENT shall not confer any rights or remedies upon any
              person or entity other than the PARTIES hereto the persons and
              entities indemnified in Article 7 (provided that such persons and
              entities shall assert any claims through the PARTIES) and their
              respective successors and permitted assigns.
