    WHICH HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

                        [LOGO OF RADNOR APPEARS HERE]
 
        THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., PHILADELPHIA TIME,
                       ON       , 1997, UNLESS EXTENDED.
 
  Radnor Holdings Corporation (the "Company" or "Radnor"), a Delaware
corporation, hereby offers, upon the terms and subject to the conditions set
forth in this Prospectus and the accompanying Letter of Transmittal (which
together constitute the "Exchange Offer"), to exchange an aggregate principal
amount of up to $100 million of 10% Senior Notes due 2003 (the "New Notes") of
the Company, which have been registered under the Securities Act of 1933, as
amended (the "Securities Act"), for a like principal amount of the issued and
outstanding 10% Senior Notes due 2003 (the "Old Notes") of the Company from the
registered holders thereof (the "Holders"). The terms of the New Notes are
identical in all material respects to the Old Notes, except for certain
transfer restrictions relating to the Old Notes. The New Notes will evidence
the same class of debt as the Old Notes and will be issued pursuant to and
entitled to the benefits of, the Indenture governing the Old Notes (the
"Indenture"). As used herein, the term "Notes" means the Old Notes and the New
Notes, treated as a single class.
 
  The Company will accept for exchange any and all Old Notes validly tendered
and not withdrawn prior to 5:00 p.m., Philadelphia time, on       , 1997 unless
extended (as so extended, the "Expiration Date"). Tenders of Old Notes may be
withdrawn at any time prior to the Expiration Date. The Exchange Offer is not
conditioned upon any minimum principal amount of Old Notes being tendered for
exchange pursuant to the Exchange Offer. The Exchange Offer is subject to
certain other customary conditions. See "The Exchange Offer."
 
  On December 5, 1996, the Company issued $100 million principal amount of Old
Notes (the "Offering") pursuant to exemptions from, or in transactions not
subject to, the registration requirements of the Securities Act and applicable
state securities laws.
 
  Interest on the Notes will be payable semi-annually on June 1 and December 1
of each year, commencing June, 1997. The Notes are not redeemable by the
Company prior to December 1, 2000, except that, at any time on or prior to
December 1, 1999, the Company, at its option, may redeem up to $25.0 million
aggregate principal amount of the Notes from the net proceeds of one or more
Public Equity Offerings (as defined) by the Company, at a redemption price of
110% of the principal amount thereof, plus accrued interest to the date of
redemption; provided that at least $75.0 million in aggregate principal amount
of the Notes remains outstanding following such redemption. On and after
December 1, 2000, the Notes will be redeemable at the option of the Company, in
whole or in part, at the redemption prices set forth herein, plus accrued
interest to the date of redemption. In the event of a Change of Control (as
defined), each holder of Notes may require the Company to repurchase all or a
portion of such holder's Notes at 101% of the principal amount thereof, plus
accrued interest to the repurchase date. See "Description of the Notes--
Optional Redemption" and "--Change of Control."

  SEE "RISK FACTORS" ON PAGE 10 OF THIS PROSPECTUS FOR A DESCRIPTION OF CERTAIN
RISKS TO BE CONSIDERED BY HOLDERS WHO TENDER THEIR OLD NOTES IN THE EXCHANGE
OFFER.

 THESE SECURITIES HAVE NOT BEEN APPROVED  OR DISAPPROVED BY THE SECURITIES AND
  EXCHANGE  COMMISSION  OR  ANY  STATE  SECURITIES  COMMISSION  NOR  HAS  THE
    SECURITIES AND EXCHANGE  COMMISSION OR ANY  STATE SECURITIES COMMISSION
     PASSED  UPON  THE  ACCURACY  OR  ADEQUACY  OF  THIS  PROSPECTUS.  ANY
      REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
 
                                  ----------
 
                  The date of this Prospectus is       , 1997.

(Continued from previous page)
 
  The New Notes will be, and the Old Notes are, senior unsecured obligations
of the Company. The New Notes will rank pari passu in right of payment with
all other existing and future senior indebtedness of the Company, including
the Old Notes. The New Notes will be, and the Old Notes are, effectively
subordinated in right of payment to all existing and future secured
indebtedness of the Company and the Company's subsidiaries, including
indebtedness under the Credit Agreements (as defined). The New Notes will be
fully and unconditionally guaranteed on a joint and several basis by
substantially all of the Company's subsidiaries. The New Guarantees will be
effectively subordinated in right of payment to all existing and future
secured indebtedness of the Guarantors, including their obligations in respect
of the Credit Agreements. Under the terms of the Indenture, the Company is
permitted, upon the satisfaction of certain conditions, to incur additional
secured indebtedness. On a pro forma basis after giving effect to the Offering
and the application of the proceeds thereof, as of September 30, 1996, the
Company and its subsidiaries would have had no outstanding indebtedness other
than the Old Notes and approximately $6.7 million outstanding under the Credit
Agreements. See "Pro Forma Consolidated Financial Data" and "Description of
the Company's Credit Facilities."
 
  For each Old Note accepted for exchange, the Holder of such Old Note will
receive a New Note having a principal amount equal to that of the surrendered
Old Note. The New Notes will bear interest from the most recent date to which
interest has been paid on the Old Notes or, if no interest has been paid on
the Old Notes, from December 5, 1996. Old Notes accepted for exchange will
cease to accrue interest from and after the date of consummation of the
Exchange Offer. Holders of Old Notes whose Old Notes are accepted for exchange
will not receive any payment in respect of accrued interest on such Old Notes.
Old Notes not tendered or not accepted for exchange will continue to accrue
interest from and after the date of consummation of the Exchange Offer. The
New Notes are being offered hereunder in order to satisfy certain obligations
of the Company contained in the Registration Rights Agreement (as defined).
Based on interpretations by the staff of the Securities and Exchange
Commission (the "SEC") as set forth in no-action letters issued to third
parties, the Company believes that New Notes issued pursuant to the Exchange
Offer in exchange for Old Notes may be offered for resale, resold and
otherwise transferred by Holders thereof (other than any Holder which is an
"affiliate" of the Company within the meaning of rule 405 under the Securities
Act), without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that such New Notes are acquired in
the ordinary course of such Holders' business and such Holders have no
arrangement or understanding with any person to engage in a distribution of
such New Notes. However, the SEC has not considered the Exchange Offer in the
context of a no-action letter and there can be no assurance that the staff of
the SEC would make a similar determination with respect to the Exchange Offer
as in such other circumstances. Each holder of the Old Notes who wishes to
exchange its Old Notes for New Notes in the Exchange Offer will be required to
make certain representations to the Company, including that (i) any New Notes
to be received by it will be acquired in the ordinary course of its business,
(ii) it has no arrangement or understanding with any person to participate in
a public distribution (within the meaning of the Securities Act) of the New
Notes and (iii) it is not an "affiliate," as defined in Rule 405 of the
Securities Act, of the Company or the Guarantors, or if it is such an
affiliate, that it will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable to it. The Letter
of Transmittal states that by so acknowledging and by delivering a prospectus,
a broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of New Notes received in exchange for Old Notes where such Old
Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities. The Company has agreed that, for a
period of 150 days after the date of this Prospectus, it will make this
Prospectus available to any broker-dealer for use in connection with any such
resale. See "Plan of Distribution."
 
  The Company will not receive any proceeds from the Exchange Offer. The
Company will pay all the expenses incident to the Exchange Offer. In the event
the Company terminates the Exchange Offer and does not accept for exchange any
Old Notes, the Company will promptly return the Old Notes to the Holders
thereof. See "The Exchange Offer."
 
                                       2

  There is no existing trading market for the New Notes, and there can be no
assurance regarding the future development of a market for the New Notes. The
Initial Purchasers (as defined) have advised the Company that they currently
intend to make a market in the New Notes. The Initial Purchasers are not
obligated to do so, however, and any market-making with respect to the New
Notes may be discontinued at any time without notice. The Company does not
intend to apply for listing or quotation of the New Notes on any securities
exchange or stock market.
 
  The Company expects that the New Notes initially will each be represented by
a single global certificate in fully registered form, except that New Notes
issued in exchange for Old Notes (i) originally purchased by institutional
investors that were Institutional Accredited Investors (as defined) who were
not QIBs (as defined) or (ii) held by QIBs who elected to take physical
delivery of these certificates instead of holding their interest through the
Global Note (as defined) (and which were thus ineligible to trade through The
Depository Trust Company) will be issued in registered form.

                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by, and is subject to, the
detailed information, consolidated financial statements and notes thereto
contained elsewhere in this Prospectus. As used herein, unless the context
otherwise requires, "Radnor" and the "Company" refer to Radnor Holdings
Corporation and its subsidiaries and their respective predecessors,"StyroChem"
refers to SP Acquisition Co. and its subsidiaries, and "J.R. Cup" refers to the
foam cup and container manufacturing business acquired (the "J.R. Cup
Acquisition") by Radnor from James River Paper Company, Inc. ("James River").
The term "Acquisitions" collectively refers to the Company's acquisition of SP
Acquisition Co. (the "StyroChem Acquisition") and the J.R. Cup Acquisition. See
"The Company--The Acquisitions."
 
                                  THE COMPANY
 
  The Company is the second largest manufacturer in the U.S. of disposable foam
cup and container products for the foodservice industry, with approximately a
35% share of this market segment in 1995. The Company manufactures foam cups
for hot and cold drinks, foam bowls and containers and thermoformed lids, as
well as the expandable polystyrene ("EPS") beads from which such foam products
are manufactured. The Company's 14 highly automated manufacturing facilities
produced 13 billion foam cups, containers and lids and 115 million pounds of
EPS beads in 1995. The brand names for the Company's foam products enjoy strong
recognition within the industry and include Dixie, COMpac, Profit Pals,
STYROcup, Handi-Kup HK and Simplicity. Through StyroChem, the Company
manufactures EPS beads for its own consumption as well as for third party
manufacturers of foam containers, insulation products and packaging products.
The Company believes that its acquisition of StyroChem, a supplier of EPS beads
to the Company since 1976, will strengthen the Company's competitive position
by lowering raw material costs, improving product quality and enhancing
manufacturing efficiencies. For the nine months ended September 30, 1996, pro
forma for the Acquisitions, the Company had net sales and EBITDA of $172.3
million and $18.6 million, respectively.
 
  Within the foodservice industry, the Company competes primarily in the
disposable cup and container market. An independent industry survey estimated
that this market had more than $2.0 billion of domestic revenues in 1994. The
use of disposable foam cups and containers has increased significantly over the
last two decades, with unit shipments (excluding lids) growing from 13 billion
in 1974 to 28 billion in 1994. Key growth factors for the foam cup and
container segment include the superior insulating quality of foam, lower labor,
maintenance and energy costs as compared to reusable products, sanitary
considerations, the growth in consumption of take-out foods and beverages and
the expansion of fast-food restaurant chains.
 
  The Company sells to more than 1,600 national, institutional and retail
customers located throughout the U.S., in Mexico and in other countries through
its 63-person sales organization and its broad network of more than 50
independent sales representatives. Foam products are sold in the U.S. to nine
of the ten largest foodservice distributors, six of the ten largest supermarket
chains and a number of large national companies and warehouse clubs. Long-term
relationships have been maintained with many of the industry's largest
companies, including Sysco Corporation, Alliant Foodservice Inc. (formerly
known as Kraft Foodservice, Inc.), K-Mart Corporation, WAL-MART Stores, Inc.,

Company also sells foam products for the consumer market through supermarket

COMPETITIVE STRENGTHS
 
  The Company has a strong competitive position in the foam segment of the
disposable cup and container market. The Company attributes its prominent
market position to the following factors:
 
  .  Customer service and quality products. The Company's attention to
     customer service and emphasis on high-quality products allow it to
     continue to meet the needs of its existing customers and attract new
     ones. Customer service is enhanced by the Company's breadth of product
     offerings, extensive order-entry system and strategically located
     manufacturing facilities. These attributes enable the Company to meet
     the national distribution requirements of its customers in an efficient
     and cost-effective manner. The Company also coordinates design efforts
     with its customers to develop new products, such as the new "flare" cup
     that combines an enhanced appearance with a stronger rim construction.
 
  .  Proprietary technology. The Company has developed a broad array of
     proprietary technology that is utilized in various stages of its
     manufacturing operations. Custom-designed and built molding equipment,
     for example, allows the Company to better meet customer requests for
     specialized container designs, custom printing or embossing, as well as
     to maintain high-volume production runs. Other proprietary technology
     includes automated materials handling and auto-case packaging machines.
     With StyroChem, the Company also has the ability to customize EPS bead
     formulations to further enhance manufacturing efficiencies and specific
     product features.
 
  .  Strong customer relationships. Long-term relationships with its
     customers have been an important factor in the Company's success. Of the
     Company's ten largest customers, nine have been purchasing products from
     the Company for more than ten years. The Company works closely with its
     customers to address a variety of needs, including custom product
     development and tooling, seasonal marketing programs and specialized
     printing requirements. The Company believes that the strength of its
     customer relationships results from consistently meeting or exceeding
     customer expectations.
 
  .  Experienced management team. The Company's management team is highly
     experienced, with a majority of the Company's senior sales,
     manufacturing, administration and engineering executives having spent
     more than 20 years in the foodservice industry. The Company's executive
     management also has extensive experience in managing and integrating
     acquisitions of businesses in various industries, including the
     foodservice industry.
 
BUSINESS STRATEGY
 
  The Company's business strategy is to increase revenues and profitability and
to further enhance its market position by emphasizing the following
initiatives:
 
  .  Cost reduction and productivity enhancements. The Company is continuing
     to reduce manufacturing costs by upgrading existing equipment and
     developing new equipment and processes that enhance productivity and
     improve manufacturing quality. Production costs have also been and will
     continue to be reduced by eliminating redundant facilities, lowering
     transportation costs and exploiting economies of scale (including raw
     material pricing) provided by the Company's high-volume production.
 
  .  Integrated manufacturing process. The StyroChem Acquisition will result
     in a more integrated manufacturing process, thereby reducing the
     Company's cost of raw materials and mitigating the impact of raw
     material price fluctuations. Control over EPS bead manufacturing should
     also provide more reliable, consistently high-quality EPS beads,
     improving the Company's overall manufacturing efficiencies.
 
 
                                       2
<PAGE>
 
  .  New markets and improved market position. The Company believes it has a
     significant opportunity to increase its share of the disposable cup and
     container market by positioning its foam products, with their superior
     insulating qualities and lower production costs, as an alternative to
     comparable paper products. The Company is also pursuing opportunities to
     increase sales of its foam products to both current and new customers in
     international markets.
 
  .  Product development and strategic acquisitions. The Company intends to
     pursue further growth opportunities through the introduction of new and
     enhanced products. In addition, the Company will seek strategic
     acquisitions, joint ventures and alliances that may broaden the
     Company's product lines.
 
                                THE ACQUISITIONS
 
  In November 1995, the Company sold its cutlery, straws and plastic cup
operations to James River. Following this divestiture, in January 1996, the
Company entered into the J.R. Cup Acquisition, which included the U.S. foam cup
and container operations of James River and which was completed in December
1996. Through the J.R. Cup Acquisition, the Company doubled its revenues, added
four manufacturing facilities and acquired additional proprietary manufacturing
processes, many of which are being integrated into the Company's existing
facilities. The J.R. Cup Acquisition has also permitted the Company's
management to rationalize its production by eliminating certain redundant
facilities. At the same time, the Company has been able to implement new
procurement programs, realign freight and related distribution arrangements
and, on a combined basis, significantly reduce manufacturing overhead and
selling, general and administrative costs. As a result of these and other
initiatives, these costs would have been reduced on a pro forma basis by
approximately $13.8 million for the year ended December 31, 1995. See "Pro
Forma Consolidated Financial Data" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Certain Effects Resulting from
the Acquisitions." A substantial majority of these cost savings have been
achieved during the first nine months of operations in 1996. See "The Company."
 
  In December 1996, the Company acquired StyroChem, one of the five largest
producers of EPS beads in the U.S. The Company believes that the StyroChem
Acquisition will strengthen its manufacturing operations by providing more
reliable, consistently high-quality EPS beads at lower prices. The StyroChem
Acquisition will also mitigate the Company's exposure to raw material price
fluctuations by allowing the Company greater flexibility in procuring raw
materials. In addition, the StyroChem Acquisition positions the Company as a
supplier of EPS beads to manufacturers of insulation and packaging products. On
a pro forma basis, StyroChem represented 22.0% of the Company's consolidated
sales for the year ended December 31, 1995. See "The Company."

                               THE EXCHANGE OFFER
 
  On December 5, 1996, the Company issued $100 million principal amount of Old
Notes. The Old Notes were sold pursuant to exemptions from, or in transactions
not subject to, the registration requirements of the Securities Act and
applicable state securities laws. Alex. Brown & Sons Incorporated and NatWest
Capital Markets Limited (the "Initial Purchasers"), as a condition to their
purchase of the Old Notes, required that the Company agree to commence the
Exchange Offer following the offering of the Old Notes. The New Notes will
evidence the same class of debt as the Old Notes and will be issued pursuant
to, and entitled to the benefits of, the Indenture. As used herein, the term
"Notes" means the Old Notes and the New Notes, treated as a single class.
 
Securities Offered..........  Up to $100 million aggregate principal amount of
                              Company's 10% Senior Notes Due 2003, which have
                              been registered under the Securities Act (the
                              "New Notes"). The terms of the New Notes and the
                              Old Notes are identical in all material respects
                              (including principal amount, interest rate,
                              maturity and ranking), except for certain
                              transfer restrictions relating to the Old Notes.
 
The Exchange Offer..........  The New Notes are being offered in exchange for a
                              like principal amount of Old Notes. The issuance
                              of the New Notes is intended to satisfy
                              obligations of the Company contained in the
                              Exchange and Registration Rights Agreement, dated
                              December 5, 1996, among the Company, the
                              Guarantors (as defined) and the Initial
                              Purchasers (the "Registration Rights Agreement").
                              For procedures for tendering the Old Notes
                              pursuant to the Exchange Offer, see "The Exchange

                              extended, the "Expiration Date"). A tender of Old
                              Notes pursuant to the Exchange Offer may be

                              freely resell New Notes received in the Exchange
                              Offer) may require the Company and the Guarantors

                              effective, a shelf registration statement under
                              the Securities Act, which would cover resales of
                              Notes by such holders (the "Shelf Registration
                              Statement"). See "The Exchange Offer" and
                              "Registration Rights."
 
Conditions to the Exchange    The Exchange Offer is not conditioned on any
Offer.......................  minimum principal amount of Old Notes being
                              tendered for exchange. The Exchange Offer is
                              subject to certain other customary conditions,
                              each of which may be waived by the Company. See
                              "The Exchange Offer--Certain Conditions to the
                              Exchange Offer."
 
                      CONSEQUENCES OF EXCHANGING OLD NOTES
 
  Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to the restrictions
on transfer of such Old Notes as set forth in the legend thereon as a
consequence of the issuance of the Old Notes pursuant to exemptions from, or in
transactions not subject to, the registration requirements of the Securities
Act and applicable state securities laws. In general, the Old Notes may not be
offered or sold, unless registered under the Securities Act, except pursuant to
an exemption from, or in a transaction not subject to, the Securities Act and
applicable state securities laws. The Company does not currently anticipate
that it will register Old Notes under the Securities Act. See "Description of
the Notes--Exchange Offer" and "Registration Rights." Based on interpretations
by the staff of the SEC, as set forth in no-action letters issued to third
parties, the Company believes that New Notes issued pursuant to the Exchange
Offer in exchange for Old Notes may be offered for resale, resold or otherwise
transferred by holders thereof (other than any holder which is an "affiliate"
of the Company within the meaning of Rule 405 under the Securities Act) without
compliance with the registration and prospectus delivery provisions of the
Securities Act, provided that such New Notes are acquired in the ordinary
course of such holders' business and such holders, other than broker-dealers,
have no arrangement or understanding with any person to participate in the
distribution of such New Notes. However, the SEC has not considered the
Exchange Offer in the context of a no-action letter and there can be no
assurance that the staff of the SEC would make a similar determination with
respect to the Exchange Offer as in such other circumstances. Each holder of
the Old Notes who wishes to exchange its Old Notes for New Notes in the
Exchange Offer will be required to make certain representations to the Company,
including that (i) any New Notes to be received by it will be acquired in the
ordinary course of its business, (ii) it has no arrangement or understanding
with any person to participate in a public distribution (within the meaning of
the Securities Act) of the New Notes and (iii) it is not an "affiliate," as
defined in Rule 405 of the Securities Act, of the Company or the Guarantors, or
if it is such an affiliate, that it will comply with the registration and
prospectus delivery requirements of the Securities Act to the extent applicable
to it. Each broker-dealer that receives New Notes for its own account in
exchange for Old Notes must acknowledge that such Old Notes were acquired by
such broker-dealer as a result of market-making activities or other trading
activities and that it will deliver a prospectus in connection with any resale
of such New Notes. See "Plan of Distribution." In addition, to comply with the
securities laws of certain jurisdictions, it may be necessary to qualify for
sale or register thereunder the New Notes prior to offering or selling such New
Notes. The Company has agreed, pursuant to the Registration Rights Agreement,
subject to certain limitations specified therein, to register or qualify the
New Notes for offer or sale under the securities laws of such jurisdictions as
any holder reasonably requests in writing. Unless a holder so requests, the
Company does not intend to register or qualify the sale of the New Notes in any
such jurisdictions. See "Risk Factors--Consequences of Failure to Exchange" and
"The Exchange Offer--Consequences of Exchanging Old Notes."

                      SUMMARY DESCRIPTION OF THE NEW NOTES
 
  The terms of the New Notes and the Old Notes are identical in all material
respects, except for certain transfer restrictions relating to the Old Notes.
If the Exchange Offer is not consummated by May 4, 1997, the interest rate
borne by the Old Notes will increase by 25 basis points per annum for each 90-
day period following such date until but excluding the date of consummation of
the Exchange Offer, up to a maximum aggregate increase of 100 basis points per
annum. The New Notes will bear interest from the most recent date to which
interest has been paid on the Old Notes or, if no interest has been paid on the
Old Notes, from December 5, 1996. Accordingly, registered holders of New Notes
on the relevant record date for the first interest payment following the
consummation of the Exchange Offer will receive interest accruing from the most
recent date to which interest has been paid on the Old Notes or, if no interest
has been paid, from December 5, 1996. Old Notes accepted for exchange will
cease to accrue interest from and after the date of consummation of the
Exchange Offer. Holders whose Old Notes are accepted for exchange will not
receive any payment in respect of interest on such Old Notes otherwise payable
on any interest payment date the record date for which occurs on or after the
consummation of the Exchange Offer.
 
Notes Offered...............  $100,000,000 aggregate principal amount of 10%

                              Company prior to December 1, 2000, except that,
                              at any time on or prior to December 1, 1999 the
                              Company, at its option, may redeem up to $25.0
                              million aggregate principal amount of the Notes
                              from the net proceeds of one or more Public
                              Equity Offerings by the Company, at a redemption
                              price of 110% of the principal amount thereof,
                              plus accrued interest to the date of redemption;
                              provided that at least $75.0 million in aggregate
                              principal amount of the Notes remains outstanding
                              following such redemption. Thereafter, the New
                              Notes will be redeemable at the option of the
                              Company, in whole or in part, at the redemption
                              prices set forth herein, plus accrued interest to
                              the date of redemption. See "Description of the
                              Notes--Optional Redemption."
 
Change of Control...........  In the event of a Change of Control, each holder
                              of New Notes will have the right to require the
                              Company to repurchase all or a portion of such
                              holder's New Notes then outstanding at a purchase
                              price equal to 101% of the principal amount
                              thereof, plus accrued and unpaid interest, if
                              any, to the repurchase date.
 
Ranking.....................  The New Notes will be senior unsecured
                              obligations of the Company and will rank pari
                              passu in right of payment with all other existing
                              and future senior indebtedness of the Company,
                              including the Old Notes. The New Notes will be
                              effectively subordinated in right of payment to
                              all existing and future secured indebtedness of
                              the Company and the Company's

                              subsidiaries, including indebtedness under the
                              Amended Credit Agreement (as defined) and the
                              Canadian Credit Agreement (as defined)
                              (collectively, the "Credit Agreements"). Under
                              the terms of the Indenture governing the New
                              Notes, the Company will be permitted, upon the
                              satisfaction of certain conditions, to incur
                              additional secured indebtedness. On a pro forma
                              basis after giving effect to the Offering, as of
                              September 30, 1996, the Company and its
                              subsidiaries would have had no outstanding
                              indebtedness other than the Old Notes and
                              approximately $6.7 million outstanding under the
                              Credit Agreements. See "Pro Forma Consolidated
                              Financial Data" and "Description of the Company's
                              Credit Facilities."
 
Guarantees..................  The New Notes will be fully and unconditionally
                              guaranteed on a joint and several basis (the "New
                              Guarantees") by substantially all of the
                              Company's subsidiaries (collectively, the
                              "Guarantors"). The New Guarantees will be
                              effectively subordinated in right of payment to
                              all existing and future secured indebtedness of
                              the Guarantors, including their obligations in
                              respect of the Credit Agreements. See
                              "Description of the Notes--Guarantees."
 
Certain Covenants...........  The Indenture contains certain covenants with
                              respect to the Company and its subsidiaries that
                              will restrict, among other things, (a) the
                              incurrence of additional indebtedness, (b) the
                              payment of dividends and other restricted
                              payments, (c) the creation of certain liens, (d)
                              the use of proceeds from sales of assets and
                              subsidiary stock, (e) sale and leaseback
                              transactions and (f) transactions with
                              affiliates. The Indenture will also restrict the
                              Company's ability to consolidate or merge with or
                              into, or to transfer all or substantially all of
                              its assets to, another person. These restrictions
                              and requirements are subject to a number of
                              important qualifications and exceptions. See
                              "Description of the Notes--Certain Covenants."

Exchange Offer;               
Registration Rights.........  Holders of New Notes (other than as set forth
                              below) are not entitled to any registration
                              rights with respect to the New Notes. Pursuant to
                              the Registration Rights Agreement, the Company
                              and the Guarantors have agreed, for the benefit
                              of the holders of Old Notes, to file an exchange
                              offer registration statement (the "Exchange Offer
                              Registration Statement"). The Registration
                              Statement of which this Prospectus is a part
                              constitutes the Exchange Offer Registration
                              Statement referred to therein. Under certain
                              circumstances described in the Registration
                              Rights Agreement, certain holders of Notes
                              (including holders who may not participate in the
                              Exchange Offer or who may not freely resell New
                              Notes received in the Exchange Offer) may require
                              the Company and the Guarantors to file, and use
                              their best efforts to cause to become effective,
                              the Shelf Registration Statement. If the Shelf

                              Statement is not filed or declared effective or
                              ceases to be effective within the applicable time
                              periods related thereto (each, a "Registration
                              Default"), the interest rate borne by Notes held
                              by such holders will increase by 25 basis points
                              per annum for the 90-day period following such
                              Registration Default. Such interest rate will
                              increase by an additional 25 basis points per
                              annum at the beginning of each subsequent 90-day
                              period, up to a maximum aggregate increase of 100
                              basis points per annum. If, subsequently, such
                              Registration Default is cured, the interest rate
                              borne by such Notes will be reduced by the amount
                              of the related increase in the interest rate. See
                              "Registration Rights."
 
Use of Proceeds.............  The Company will not receive any proceeds from
                              the Exchange Offer. The net proceeds of the
                              Offering were used to repay certain indebtedness
                              of the Joint Venture (as defined) relating to
                              J.R. Cup, to acquire the interest in the Joint
                              Venture not then held by the Company, to purchase
                              the outstanding capital stock of and other equity
                              interests in StyroChem, to redeem certain shares
                              of the Company's preferred stock and certain
                              then-outstanding equity warrants held by a third
                              party and for general corporate purposes.
 
Risk Factors................  Potential investors in the New Notes should
                              carefully consider the matters set forth under
                              the caption "Risk Factors" prior to making an
                              investment decision with respect to the New
                              Notes.

          SUMMARY HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL DATA
 
  The following summary financial, operating and pro forma data were derived
from the consolidated financial statements of Radnor, including the notes
thereto (the "Radnor Financial Statements"), as well as the selected financial,
operating and pro forma information included elsewhere in this Prospectus. The
pro forma consolidated statements of operations data reflect the Acquisitions
and the sale of the Notes as if they had occurred on January 1 of each
respective period. The pro forma consolidated balance sheet data reflect the
StyroChem Acquisition and the sale of the Notes as if they had occurred on
September 30, 1996. 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 the
Company as if the Acquisitions and the sale of 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. The information set forth below should be
read in conjunction with "Pro Forma Consolidated Financial Data," "Selected
Consolidated Financial Data," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and the Financial Statements (as
defined) included elsewhere herein.

(1) The historical financial data include Radnor and its consolidated
    subsidiaries, excluding discontinued operations, for each of the three
    years in the period ended December 31, 1995 and as of and for the nine
    months ended September 30, 1996. The Company's discontinued operations were
    the cutlery, straws and plastic cup operations, which were sold in 1995.
    Prior to January 20, 1996, the Company's results from continuing operations
    do not include the results of J.R. Cup, which was acquired on that date.
(2) The historical financial data for the nine months ended September 30, 1995
    and 1996 are unaudited.
(3) Pro forma interest expense does not include amortization of estimated debt
    issuance costs related to the Credit Agreements and the Notes. The interest
    rate on the Notes is 10%. The assumed interest rate on the Credit
    Agreements is approximately 8.5%.
(4) The Company recorded no federal income tax expense during the periods
    presented due to the incurrence of operating losses or the utilization of
    net operating loss carryforwards during those periods.
(5) EBITDA represents income (loss) from continuing operations before interest,
    income tax expense, depreciation and amortization and restructuring and
    other non-recurring charges. EBITDA is presented here to provide additional
    information about the Company's ability to meet its future debt service,
    capital expenditure and working capital requirements. 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.
(6) Each M Unit consists of 1,000 foam cups, containers or lids.

                                 RISK FACTORS
 
  Potential investors in the New Notes, including Holders of the Old Notes
considering the Exchange Offer, should consider carefully all of the
information set forth in this Prospectus and, in particular, should evaluate
the following before making an investment decision with respect to the New
Notes, although the risk factors set forth below (other than "--Consequences
of Failure to Exchange Old Notes") are generally applicable to the Old Notes
as well as the New Notes.
 
CONSEQUENCES OF FAILURE TO EXCHANGE OLD NOTES
 
  Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to the provisions
in the Indenture regarding transfer and exchange of the Old Notes and the
restrictions on transfer of such Old Notes as set forth in the legend thereon
as a consequence of the issuance of the Old Notes pursuant to exemptions from,
or in transactions not subject to, the registration requirements of the
Securities Act and applicable state securities laws. In general, the Old Notes
may not be offered or sold, unless registered under the Securities Act and
applicable state securities laws. The Company does not currently anticipate
that it will register Old Notes under the Securities Act. See "The Exchange
Offer" and "Registration Rights." Based on interpretations by the staff of the
SEC, as set forth in no-action letters issued to third parties, the Company
believes that New Notes issued pursuant to the Exchange Offer in exchange for
Old Notes may be offered for resale, resold or otherwise transferred by
holders thereof (other than any such holder which is an "affiliate" of the
Company within the meaning of Rule 405 under the Securities Act) without
compliance with the registration and prospectus delivery provisions of the
Securities Act, provided that such New Notes are acquired in the ordinary
course of such holders' business and such holders, other than broker-dealers,
have no arrangement or understanding with any person to participate in the
distribution of such New Notes. However, the SEC has not considered the
Exchange Offer in the context of a no-action letter and there can be no
assurance that the staff of the SEC would make a similar determination with
respect to the Exchange Offer as in such other circumstances. Each holder of
the Old Notes who wishes to exchange its Old Notes for New Notes in the
Exchange Offer will be required to make certain representations to the
Company, including that (i) any New Notes to be received by it will be
acquired in the ordinary course of its business, (ii) it has no arrangement or
understanding with any person to participate in a public distribution (within
the meaning of the Securities Act) of the New Notes and (iii) it is not an
"affiliate," as defined in Rule 405 of the Securities Act, of the Company or
the Guarantors, or if it is such an affiliate, that it will comply with the
registration and prospectus delivery requirements of the Securities Act to the
extent applicable to it. If any Holder is an affiliate of the Company or in
engaged in or intends to engage in or has any arrangement or understanding
with respect to the distribution of the New Notes to be acquired pursuant to
the Exchange Offer, such Holder (i) may not rely on the applicable
interpretations of the staff of the SEC and (ii) must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. Each broker-dealer that receives New
Notes for its own account in exchange for Old Notes pursuant to the Exchange
Offer must acknowledge that such Old Notes were acquired by such broker-dealer
as a result of market-making activities or other trading activities and that
it will deliver a prospectus in connection with any resale of such New Notes.
The Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-
dealer in connection with resales of New Notes received in exchange for Old
Notes where such Old Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities. The Company has agreed
that, for a period of 150 days after the date of this Prospectus, it will make
this Prospectus available to any broker-dealer for use in connection with any
such resale. See "Plan of Distribution." In addition, to comply with the
securities laws of certain jurisdictions, if applicable, the New Notes may not
be offered or sold unless they have been registered or qualified for sale in
such jurisdictions or an exemption from registration or qualification is
available and is complied with. The
 
                                      10
<PAGE>
 
Company has agreed, pursuant to the Registration Rights Agreement, subject to
certain limitations specified therein, to register or qualify the New Notes
for offer or sale under the securities laws of such jurisdictions as any
holder reasonably requests in writing. Unless a holder so requests, the
Company does not currently intend to register or qualify the sale of the New
Notes in any jurisdictions. See "The Exchange Offer."
 
ADDITIONAL LEVERAGE
 
  On a pro forma basis after giving effect to the sale of the Old Notes and
the application of the estimated net proceeds therefrom, the Company's total
debt would have been $106.7 million as of September 30, 1996, the Company's
ratio of pro forma income before taxes to fixed charges would have been 1.4 to
1 for the nine months ended September 30, 1996 and the Company and the
Guarantors would have had, subject to certain restrictions (including
borrowing base limitations), the ability to draw up to $25.0 million of
additional secured senior indebtedness under the Credit Agreements.
 
  A substantial increase in the Company's leverage and obligations could have
important consequences to the holders of Notes, including (i) the impairment
of the Company's ability to obtain additional financing for working capital,
capital expenditures, acquisitions or other purposes, (ii) the use of a
substantial portion of the Company's cash flow from operations for debt
service and (iii) making the Company more vulnerable to economic downturns and
limiting its ability to withstand competitive pressures.
 
  In addition, the Company's operating flexibility with respect to certain
business matters are limited by covenants contained in the Indenture and the
Credit Agreements. Among other things, these covenants limit the ability of
the Company and its subsidiaries to incur additional indebtedness, create
liens upon assets, apply the proceeds from disposal of assets, make dividend
payments and other distributions on capital stock and redeem any capital
stock. There can be no assurance that such covenants will not adversely affect
the Company's ability to finance its future operations or capital needs or to
engage in other business activities that may be in the interest of the
Company. See "Description of the Company's Credit Facilities" and "Description
of the Notes--Certain Covenants."
 
  The Company expects that its cash flow will be sufficient to cover its
expenses, including fixed charges. However, no assurance can be given that the
Company's operating results will be sufficient for the Company to meet such
obligations. The Company's ability to satisfy its obligations will be
dependent upon its future performance, which is subject to prevailing economic
conditions and financial, business and other factors, including factors beyond
the Company's control.
 
RAW MATERIAL PRICE VOLATILITY
 
  The Company's foam products are manufactured from EPS beads, which are
produced from styrene monomer. Styrene monomer is a commodity petrochemical
that is readily available in bulk quantities from numerous large, vertically
integrated chemical companies. Since the consummation of the StyroChem
Acquisition, the Company has purchased styrene monomer to produce EPS beads
for its own consumption and has also continued to purchase EPS beads from Nova
Chemicals, Inc., which has been a long-term supplier to the Company. There are
currently more suppliers of styrene monomer than there are suppliers of cup-
grade EPS beads. Prices for both styrene monomer and EPS beads will fluctuate,
principally due to fluctuations in petrochemical feedstock prices, but also
because of supply and demand in the styrene monomer and EPS bead markets.
 
  If raw material prices increase and the Company is unable to pass such price
increases on to its customers, employ successful hedging strategies, enter
into long-term supply contracts at favorable prices or buy on the spot market
at favorable prices, the Company's profitability may be adversely affected. To
the extent that the Company's supply of raw materials is hindered and no
alternative source can be found, the Company's profitability may be adversely
affected.
 
 
                                      11
<PAGE>
 
  The Company believes that the StyroChem Acquisition and the new long-term
supply agreement with Chevron Chemical Company ("Chevron") for the purchase of
styrene monomer will mitigate the Company's exposure to fluctuations in styrene
monomer prices. The new agreement guarantees a supply of up to 11.6 million
pounds of styrene monomer per month at favorable prices, which include rebates
for all amounts purchased when purchases exceed 120 million pounds per year.
See "Business--Raw Materials."
 
OPERATING LOSSES
 
  The Company had income from continuing operations for the nine months ended
September 30, 1996 of $2.8 million. Before giving effect to any pro forma
adjustments and without regard to income from discontinued operations, the
Company had losses from continuing operations of approximately $4.7 million,
$0.3 million and $7.9 million for the years ended December 31, 1993, 1994 and
1995, respectively. The losses in 1993 and 1994 were primarily attributable to
the high level of fixed costs in relation to sales and the losses in 1995 were
attributable to the industry-wide increase in raw material costs, partially
offset by an increase in selling prices. On a pro forma basis, the Company
would have had a loss of $2.3 million for the year ended December 31, 1995 and
income from continuing operations of $4.1 million for the nine months ended
September 30, 1996, respectively. There can be no assurance that the Company's
future operations will continue to generate operating or net income or
sufficient cash flow to permit the Company to satisfy its obligations. See "Pro
Forma Consolidated Financial Data," "Selected Consolidated Financial Data" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
COMPETITION
 
  The Company competes in the highly competitive foodservice industry. Many of
the Company's competitors are larger and have significantly greater resources
than the Company. Within the foam segment of the disposable cup and container
market, the Company competes principally with Dart Container Corp. ("Dart"),
which has significantly greater financial resources than the Company and
controls the largest share of this market segment. See "Business--Competition."
 
DEPENDENCE ON KEY CUSTOMERS
 
  The Company supplies products to a number of large national companies and to
a number of large foodservice distributors. Pro forma for the Acquisitions, no
customer represented more than 9.0% of the Company's net sales for 1995. In
addition, the five largest accounts represented approximately 30.0% of the
Company's pro forma net sales for the year ended December 31, 1995. Although
the Company has not lost sales from its key customers in 1995, 1996 or 1997 to
date, if any of such customers substantially reduces its level of purchases
from the Company, the Company's profitability may be adversely affected.
Moreover, continued consolidation among distributors in the foodservice
industry could result in an increasingly concentrated customer base or the loss
of certain customers. See "Business--Sales, Marketing and Customers."
 
SUCCESSFUL INTEGRATION OF ACQUISITIONS
 
  The integration of acquired businesses may result in unforeseen difficulties
that require a disproportionate amount of management's attention and the
Company's resources. There can be no assurance that the Company will be able to
achieve the synergies it anticipates from recent and current acquisitions or
that suitable additional acquisitions will be available.
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company is dependent on the management experience and continued services
of the Company's executive officers, including Michael T. Kennedy. The loss of
the services of these officers could have a
 
                                       12
<PAGE>
 
material adverse effect on the Company's business. In addition, the Company's
continued growth depends on its ability to attract and retain experienced key
employees.
 
CONTROL OF THE COMPANY
 
  Michael T. Kennedy, the President, Chief Executive Officer and sole director
of the Company, beneficially owns 85.0% of the voting common stock of the
Company. Consequently, Mr. Kennedy has the ability to control the Company's
management, policies and financing decisions, to elect all of the Company's
directors and to control the vote on all matters coming before the stockholders
of the Company. As a result, circumstances could arise in which the interests
of Mr. Kennedy could be in conflict with the interests of the holders of Notes.
 
ENVIRONMENTAL MATTERS
 
  The Company's operations are subject to federal, state, foreign and local
environmental laws and regulations. As a result, the Company is involved from
time to time in administrative or legal proceedings relating to environmental
matters. There can be no assurance that the aggregate amount of future clean up
costs and other environmental liabilities will not be material. The Company
cannot predict what environmental legislation or regulations will be enacted in
the future, how existing or future laws or regulations will be administered or
interpreted or what environmental conditions may be found to exist. Enactment
of more stringent laws or regulations or more strict interpretation of existing
laws and regulations may require additional expenditures by the Company, some
of which could be material. As part of the StyroChem Acquisition, approximately
$1.4 million of the purchase price has been placed in escrow and may be used by
the Company to offset certain expenses associated with specified environmental
matters relating to StyroChem's Texas and Quebec facilities. However, there can
be no assurance that the escrowed funds will be sufficient to offset all
expenses associated with such environmental matters. See "Business--
Environmental Matters."
 
FORWARD-LOOKING STATEMENTS
 
  All statements contained in this Prospectus that are not historical facts,
including but not limited to the Company's plans for expansion, facility
consolidation and acquisitions, are based on current expectations. These
statements are forward-looking (as defined in the U.S. Private Securities
Litigation Reform Act of 1995) in nature and involve a number of risks and
uncertainties. Actual results may vary materially, as discussed in this "Risk
Factors" section. The factors that could cause actual results to vary
materially include: the availability and pricing of raw materials; the
availability of capital to finance the Company's expansion plans on terms
satisfactory to the Company; the integration of any new businesses acquired by
the Company; general business and economic conditions and other risks that may
be described from time to time in the reports that the Company will be required
to file with the SEC following consummation of the Exchange Offer. The Company
cautions potential investors not to place undue reliance on any such forward-
looking statements.
 
CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control, each holder of Notes may require
the Company to repurchase all or a portion of such holder's Notes. If a Change
of Control were to occur, there can be no assurance that the Company would have
sufficient financial resources, or would be able to arrange financing to pay
the repurchase price for all Notes tendered by holders thereof. Further, the
provisions of the Indenture may not afford holders of Notes protection in the
event of a highly leveraged transaction, reorganization, restructuring, merger
or similar transaction involving the Company that may adversely affect holders
of Notes, if such transaction does not result in a Change of Control. In
addition, the terms of the Credit Agreements may limit the Company's ability to
purchase any Notes and will also identify certain events that would constitute
a Change of Control, as well as certain other events with respect to the
Company or certain of its subsidiaries, that would constitute an event of
default under the Credit
 
                                       13
<PAGE>
 
Agreements. See "Description of the Company's Credit Facilities." Any future
credit agreements or other agreements relating to other indebtedness to which
the Company becomes a party may contain similar restrictions and provisions. In
the event a Change of Control occurs at a time when the Company is prohibited
from purchasing Notes, the Company could seek the consent of its lenders to the
purchase of Notes or could attempt to refinance the borrowings that contain
such prohibition. If the Company does not obtain such consent or repay such
borrowing, the Company would remain prohibited from purchasing Notes. In such
case, the Company's failure to purchase tendered Notes would constitute an
Event of Default under the Indenture, which would, in turn, constitute a
further default under certain of the Company's existing debt agreements and may
constitute a default under the terms of other indebtedness that the Company may
enter into from time to time. See "Description of the Notes--Change of
Control."
 
RANKING OF THE NOTES
 
  The New Notes will be, and the Old Notes are, senior unsecured obligations of
the Company. The New Notes will rank pari passu in right of payment with all
other existing and future senior indebtedness of the Company, including the Old
Notes. The New Notes will be, and the Old Notes are, effectively subordinated
in right of payment to all existing and future secured indebtedness of the
Company and the Company's subsidiaries, including indebtedness under the Credit
Agreements. Loans under the Amended Credit Agreement are secured by the
inventory, accounts receivable, general intangibles, trademarks and licenses
and the proceeds thereof of the Company and its U.S. subsidiaries. Loans under
the Canadian Credit Agreement are secured by all of the material assets of the
Company's Canadian subsidiary. Under the terms of the Indenture, the Company is
permitted, upon the satisfaction of certain conditions, to incur additional
secured indebtedness. See "Description of the Company's Credit Facilities,"
"Description of the Notes--Ranking" and "--Certain Covenants."
 
HOLDING COMPANY STRUCTURE; POSSIBLE INVALIDITY OF GUARANTEES
 
  The Company is a holding company, the assets of which consist principally of
the stock of its subsidiaries through which it conducts its operations. The
Company will be dependent upon dividends and other payments from its
subsidiaries to generate the funds necessary to meet its obligations, including
the payment of principal of and interest on the Notes. Therefore, the Company's
ability to pay interest on the Notes and to satisfy its other obligations will
depend upon the future operating performance of its subsidiaries, which will be
affected by economic conditions, and financial, business and other factors,
some of which are beyond the Company's control. In addition, the ability of the
Company's subsidiaries to make such payments are subject to, among other
things, applicable state laws.
 
  The Company's obligations on the New Notes will be, and the Company's
obligations on the Old Notes are, guaranteed on a joint and several basis by
the Guarantors. The incurrence by the Company and the Guarantors of the
indebtedness evidenced by the Notes, the full and unconditional, joint and
several guarantees by the Guarantors of the Old Notes (the "Old Guarantees")
and the New Guarantees, and the use by the Company of the proceeds of the Old
Notes to effect the Acquisitions, may be subject to review under relevant
federal and state fraudulent conveyance statutes in a bankruptcy or
reorganization case or a lawsuit by or on behalf of creditors of the Company or
the Guarantors. Under these statutes, if a court were to find that at the time
the Notes, or the Old Guarantees or the New Guarantees (collectively, the
"Guarantees"), as the case may be, were issued, (a) the Company or any of the
Guarantors issued the Notes or a Guarantee with the intent of hindering,
delaying or defrauding current or future creditors or (b)(i) the Company or any
of the Guarantors received less than reasonably equivalent value or fair
consideration for issuing the Notes or a Guarantee, as the case may be, and
(ii) the Company or any such Guarantor, as the case may be, (A) was insolvent
or was rendered insolvent by reason of the Acquisitions, the Offering and the
Exchange Offer, (B) was engaged, or was about to engage, in a business or
transaction for which its assets constituted unreasonably small capital or (C)
intended to incur, or believed that it would incur, debts beyond its ability to
pay as such debts matured (as all of the foregoing terms are
 
                                       14
<PAGE>
 
defined in or interpreted under the fraudulent conveyance statutes), such
court could void the Notes or such Guarantee or subordinate such obligations
to presently existing and future indebtedness of the Company and such
Guarantor.
 
  The measure of insolvency for purposes of the foregoing considerations will
vary depending upon the law of the jurisdiction that is being applied in any
such proceeding. Generally, however, the Company and the Guarantors would be
considered insolvent if, at the time they incur or incurred the indebtedness
constituting the Notes or the Guarantees, either (a) the fair market value (or
fair saleable value) of their assets on a going concern basis is less than the
amount required to pay the probable liability on their total existing debts
and liabilities (including contingent liabilities) as they become absolute and
matured or (b) they are incurring debt beyond their ability to pay as such
debt matures.
 
  In addition, the Guarantees may be subject to the claim that, since the
Guarantees were incurred for the benefit of the Company (and only indirectly
for the benefit of the Guarantors), they were incurred for less than
reasonably equivalent value or fair consideration. As described above, a court
could therefore void the Guarantees or subordinate them to other obligations
of the Guarantors.
 
  The Company and the Guarantors believe that, at the time of the issuance of
the Notes and the Guarantees, as the case may be, the Company and the
Guarantors were or will be, as the case may be, (a) neither insolvent nor
rendered insolvent thereby, (b) in possession of sufficient capital to pay
their debts as the same mature or become due and to operate their respective
businesses effectively and (c) incurring debts within their respective
abilities to pay. In reaching the foregoing conclusions, the Company and the
Guarantors have relied upon their analysis of internal cash flow projections
and estimated values of assets and liabilities of the Company and the
Guarantors (including rights of contribution and indemnification in connection
with the Guarantees). There can be no assurance, however, that a court passing
on such questions would reach the same conclusions. See "Description of the
Notes--Guarantees."
 
LACK OF PUBLIC MARKET FOR THE NOTES
 
  The New Notes are being offered to the Holders of the Old Notes. The Old
Notes were issued on December 5, 1996 to qualified institutional buyers and
institutional accredited investors and the Old Notes issued to qualified
institutional buyers are eligible for trading in PORTAL, the National
Association of Securities Dealers' screenbased, automated market for trading
of securities eligible for resale under Rule 144A under the Securities Act. To
the extent that Old Notes are tendered and accepted in the Exchange Offer, the
trading market for the remaining untendered Old Notes could be adversely
affected. There can be no assurance regarding the development of a market for
the New Notes, or the ability of holders of the New Notes to sell their New
Notes or the price at which such holders may be able to sell their New Notes.
If such a market were to develop, the New Notes could trade at prices that may
be higher or lower than their principal amount or purchase price, depending on
many factors, including prevailing interest rates, the Company's operating
results and the market for similar securities. Each Initial Purchaser has
advised the Company that it currently intends to make a market in the New
Notes. The Initial Purchasers are not obligated to do so, however, and any
market-making with respect to the New Notes may be discontinued at any time
without notice. In addition, such market-making activities will be subject to
the limits imposed by the Securities Act and the Exchange Act and may be
limited during the Exchange Offer or the pendency of an applicable Shelf
Registration Statement. Therefore, there can be no assurance as to the
liquidity of any trading market for the New Notes or that an active public
market for the New Notes will develop. The Company does not intend to apply
for listing or quotation of the New Notes on any securities exchange or stock
market.
 
  Historically, the market for noninvestment grade debt has been subject to
disruptions that have caused substantial volatility in the prices of such
securities. There can be no assurance that the market for the New Notes will
not be subject to similar disruptions. Any such disruptions may have an
adverse effect on holders of the New Notes.

                                  THE COMPANY
 
BACKGROUND
 
  The Company was incorporated as a Delaware corporation in November 1991 in
connection with its acquisition of the plastic and foam cup and container
business of Kimberly-Clark Tissue Company formerly known as Scott Paper Company
("KCTC"). In February 1992, the Company, through WinCup Holdings, Inc.
("WinCup"), acquired all of the capital stock of Scott Container Products
Group, Inc. from Scott Paper Company. In November 1995, the Company sold to
James River its cutlery, straws and plastic cup operations. See Note 1 to the
Radnor Financial Statements.
 
  The Company, through WinCup and J.R. Cup, has been manufacturing foam cups
and containers for more than 30 years. The WinCup foam cup and container
business was established in 1961 and began purchasing EPS beads from StyroChem
when that company began operations in 1976. J.R. Cup's predecessor began
manufacturing foam cups and containers in 1963 and was purchased by James River
in 1986. The Company believes that the consolidation of StyroChem and J.R. Cup
with the Company's foam cup and container operations is a significant strategic
opportunity due to the technological synergies, expected cost reductions and
broader geographic distribution of the combined businesses.
 
THE ACQUISITIONS
 
  In January 1996, WinCup acquired substantially all of the assets of the U.S.
foam cup and container operations of James River, which comprised James River's
J.R. Cup division. The J.R. Cup Acquisition was structured as a joint venture
between WinCup and James River known as WinCup Holdings, L.P. (the "Joint
Venture"). The Company used a portion of the proceeds of the Offering to
purchase James River's interest in the Joint Venture and repay certain
subordinated notes issued to James River. See Note 1 to the Radnor Financial
Statements. In connection with the purchase of James River's interest in the
Joint Venture, the Company entered into various agreements with James River,
including five-year extensions of a sales agent agreement, an equipment use
agreement and a license relating to certain trademark rights, a sublease on
manufacturing and warehouse facilities and a settlement of a dispute relating
to certain disability claims. See "Business--Proprietary Technology and
Trademarks," "--Facilities" and "--Legal Proceedings."
 
  Through the J.R. Cup Acquisition, the Company doubled its revenues, added
four manufacturing facilities and acquired proprietary manufacturing processes,
many of which are being integrated into the Company's existing facilities. The
J.R. Cup Acquisition has also permitted the Company's management to rationalize
its production by eliminating certain redundant facilities. At the same time,
the Company has been able to implement new procurement programs, realign
freight and related distribution arrangements and, on a combined basis,
significantly reduce manufacturing overhead and selling, general and
administrative costs. As a result of these and other initiatives, these costs
would have been reduced on a pro forma basis by approximately $13.8 million for
the year ended December 31, 1995. See "Pro Forma Consolidated Financial Data"
and "Management's Discussion and Analysis of Financial Condition and Results of
Operations--Certain Effects Resulting from the Acquisitions." A substantial
majority of these cost savings have been achieved during the first nine months
of operations in 1996.
 
  In December 1996, the Company acquired StyroChem for an aggregate cash
purchase price of $29.0 million plus $2.0 million of assumed indebtedness and
consulting payments. The purchase price is subject to post-closing adjustment
based upon any positive or negative change in StyroChem's net working capital
between August 3, 1996 and the closing date of the acquisition, for which a
$1.0 million escrow account has been created. In addition, approximately $1.4
million of the purchase price has been placed in a separate escrow account, and
may be used by the Company to offset expenses associated with specified
environmental matters relating to StyroChem's Texas and Quebec facilities. See
"Business--Environmental Matters."
 
 
                                       16
<PAGE>
 
  As part of the acquisition, StyroChem's President and majority voting
stockholder entered into an agreement with the Company that prohibits him from
engaging in certain businesses competitive with the Company in the U.S. and
Canada for a period of five years and from interfering with or entering into
employment relationships with StyroChem employees for a period of two years.
StyroChem's President and majority stockholder also entered into a six-month
consulting agreement with the Company pursuant to which he provides up to 40
hours a month of consulting services, as requested by the Company.
 
  The Company believes that the StyroChem Acquisition will strengthen the
Company's manufacturing operations by providing more reliable, consistently
high-quality EPS beads at lower prices and will mitigate the Company's
exposure to raw material price fluctuations by allowing greater flexibility in
procuring raw materials. In addition, the StyroChem Acquisition positions the
Company as a supplier of EPS beads to manufacturers of insulation and
packaging products.
 
GENERAL
 
  The Company's executive offices are located at Three Radnor Corporate
Center, Suite 300, 100 Matsonford Road, Radnor, Pennsylvania 19087, and its
telephone number is (610) 341-9600.

                     PRO FORMA CONSOLIDATED FINANCIAL DATA
 
  The following pro forma consolidated financial data have been prepared by
the Company based on certain adjustments to the Radnor Financial Statements,
the financial statements of the J.R. Cup Foam Container Operations of James
River Paper Company, Inc., including the notes thereto (the "J.R. Cup
Financial Statements") and the consolidated financial statements of StyroChem,
including the notes thereto (the "StyroChem Financial Statements"), all of
which are included elsewhere herein. The Radnor Financial Statements, the J.R.
Cup Financial Statements and the StyroChem Financial Statements are referred
to collectively as the "Financial Statements." The pro forma consolidated
statements of operations reflect the Acquisitions and the sale of the Notes as
if they had occurred on January 1 of each respective period. The pro forma
consolidated balance sheet reflects the StyroChem Acquisition and the sale of
the Notes as if they had occurred on September 30, 1996. 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 the Company as if the Acquisitions and
the sale of 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. See "The Company--The Acquisitions," "Capitalization," "Selected
Consolidated Financial Data," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and the Financial Statements

                     SELECTED CONSOLIDATED FINANCIAL DATA
 
  The selected consolidated financial data presented below as of December 31,
1994 and 1995, and for the years ended December 31, 1993, 1994 and 1995, have
been derived from the audited Radnor Financial Statements and should be read
in conjunction with such audited Radnor Financial Statements which are
included herein. The selected consolidated financial data presented below as
of December 31, 1991, 1992 and 1993 and for the years ended December 31, 1991
and 1992 have been derived from Radnor's and its predecessors' unaudited
consolidated financial statements not included herein. The data as of and for
the nine months ended September 30, 1995 and September 30, 1996 have been
derived from the unaudited Radnor Financial Statements included herein. The
unaudited Radnor Financial Statements have been prepared on the same basis as
the audited Radnor Financial Statements included herein and, in the opinion of
management, include all adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation of the Company's financial
position and results of operations for the period. The results of operations
for interim periods are not necessarily indicative of the results to be
expected for the full year. Financial results for the nine months ended
September 30, 1996 are not fully comparable to the nine months ended September
30, 1995 because of the January 1996 acquisition of the J.R. Cup business. The
nine months ended September 30, 1995 and the years ended December 31, 1993,
1994 and 1995 contain only the results of operations from the Radnor foam cup
and container business and exclude any adjustments to reflect the J.R. Cup
Acquisition. The selected consolidated financial data should be read in
conjunction with "Pro Forma Consolidated Financial Data," "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
the Radnor Financial Statements included elsewhere in this Prospectus.

(1) The historical financial data for the periods prior to February 29, 1992
    and as of December 31, 1991 include only the results of operations and
    balance sheet data of Scott Container Products Group, Inc. which was
    acquired by Radnor from KCTC on February 28, 1992. The Company's financial
    data do not include the results from the cutlery, straws and plastic cup
    operations, which were sold in 1995 and reflected as discontinued
    operations in the Radnor Financial Statements. See Note 1 to the Radnor
    Financial Statements.
(2) The historical financial data include Radnor and its consolidated
    subsidiaries, excluding discontinued operations, as of and for the nine
    months ended September 30, 1996. Prior to January 20, 1996, the Company's
    results from continuing operations do not include the results of J.R. Cup,
    which was acquired on that date.
(3) The Company recorded no federal income tax expense during the periods
    presented due to the incurrence of operating losses or the utilization of
    net operating loss carryforwards during those periods.
(4) EBITDA represents income (loss) from continuing operations before
    interest, income tax expense, depreciation and amortization and
    restructuring and other non-recurring charges. EBITDA is presented here to
    provide additional information about the Company's ability to meet its
    future debt service, capital expenditure and working capital requirements.
    EBITDA is not a measure of financial performance under 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.
(5) For purposes of this computation, fixed charges consist of interest,
    amortization of deferred financing fees and that portion of lease rental
    expense representative of the interest factor (deemed to be one-third of
    lease rental expense). Earnings consist of income from continuing
    operations before income taxes plus fixed charges.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
  The Company is the second largest producer in the U.S. of foam cup and
container products for the foodservice industry. The Company manufactures foam
cups for hot and cold drinks, foam bowls and containers and thermoformed lids
and sells its products to national, institutional and retail customers located
throughout the U.S., in Mexico and in other countries. The Company, through
its predecessors, has been manufacturing foam cups and containers since 1961.
 
  The Company was organized in 1991 to facilitate the acquisition of Scott
Container Products Group, Inc. from KCTC, which occurred in February 1992. In
January 1996, the Company executed a joint venture agreement with James River,
which resulted in the acquisition of its J.R. Cup business. In December 1996,
the Company purchased James River's interest in the Joint Venture and repaid
certain subordinated notes issued to James River. For a further description of
the J.R. Cup Acquisition, see Note 1 to the Radnor Financial Statements. In
addition, at the same time, the Company also purchased the outstanding capital
stock of and other equity interests in StyroChem. StyroChem supplies the
Company with approximately 50% of the EPS beads used in its manufacture of
foam products. See "The Company--The Acquisitions."
 
 Net sales
 
  Net sales represent the gross sales of the Company's products less cash
discounts and allowances, which historically have averaged approximately 2% of
net sales. Sales incentives and volume rebates to customers are classified as
selling expenses and are included in selling, general and administrative
expenses.
 
 Cost of goods sold
 
  Raw material costs represent a large portion of the Company's cost of goods
sold and are susceptible to price fluctuations based upon supply and demand
and general market conditions. Beginning in April 1994 and continuing through
August 1995, prices of raw materials reached historically high levels. Since
that time, raw material prices have declined and are near early 1994 levels.
Although future raw material prices cannot be predicted with accuracy, the
prices for the raw materials used in the Company's products are forecasted by
independent industry surveys and producer reports to remain stable over the
next several years.
 
  In connection with the Company's engineering initiatives, the Company has
invested significant resources in research and development. The Company
expenses all research and development costs in the period incurred and
includes such costs in cost of goods sold. As a percentage of net sales, these
costs have represented 0.6%, 0.5%, 0.9% and 1.1% in 1993, 1994, and 1995 and
for the nine months ended September 30, 1996, respectively.
 
 Distribution expense
 
  The Company ships its products from manufacturing locations using a
combination of common carriers, its own fleet and leased vehicles.
Distribution expense consists of the costs to ship products, including costs
of labor and leased vehicles.
 
 Selling, general and administrative expenses
 
  Selling, general and administrative expenses were partially allocated to the
cutlery, straws and plastic cup operations which were sold and reported as
discontinued operations in 1995. These allocated
 
                                      27
<PAGE>
 
expenses were not eliminated but were absorbed in the remaining business in
anticipation of the J.R. Cup Acquisition in January 1996. The J.R. Cup
Acquisition also required the Company to incur additional sales and marketing
costs.
 
 Restructuring charges
 
  During the first quarter of 1996, the Company closed its Des Plaines,
Illinois manufacturing facility and consolidated those operations into its
West Chicago, Illinois facility. In addition, the Company consolidated certain
warehousing facilities and relocated its executive offices to Radnor,
Pennsylvania. The plant and warehouse consolidations, together with the
relocation of its executive offices, resulted in $0.9 million of restructuring
charges during the nine months ended September 30, 1996.
 
 Net operating loss carryforwards
 
  The Company had net operating loss carryforwards of approximately $11.7
million as of September 30, 1996. The carryforwards expire through 2010.
Management believes that the Company's future taxable income will be
sufficient to use the $11.7 million of net operating loss carryforwards prior
to their expiration; however, there can be no assurance that the Company's net
operating loss carryforwards will become available or that the Company will
generate future taxable income. The benefit of the net operating loss
carryforwards has not been reflected in the Company's financial statements.
 
COMPARABILITY OF PERIODS
 
  Financial results for the nine months ended September 30, 1996 are not fully
comparable to the nine months ended September 30, 1995 because of the January
1996 acquisition of the J.R. Cup business. The nine months ended September 30,
1995 and the years ended December 31, 1993, 1994 and 1995 contain only the
results of operations from the Radnor foam cup and container business and
exclude any adjustments to reflect the J.R. Cup Acquisition.

CERTAIN EFFECTS RESULTING FROM THE ACQUISITIONS
 
  The Company believes that the Acquisitions will result in certain cost
savings, including, but not limited to, the following: (i) the consolidation
of certain manufacturing and administrative functions, (ii) reductions in raw
material costs, (iii) the elimination of redundant facilities and (iv) the
realignment of customer shipping locations. The Company believes that, had
such cost savings been implemented as of January 1, 1995, such savings would
have approximated $16.2 million and $3.5 million in the aggregate for 1995 and
the nine months ended September 30, 1996, respectively, as follows:

</TABLE>
 
  In addition to these cost savings, the Company believes that it may be able
to achieve additional cost savings from (i) reductions in facility costs
arising from renegotiated rents or reduced space, (ii) a reduction in labor
costs from production efficiencies and a reduced number of direct production
employees and (iii) potential further raw materials cost reductions from the
StyroChem Acquisition.

 NINE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 1995
 
  Net sales for the nine months ended September 30, 1996 were $128.1 million,
almost double the net sales of $64.1 million for the nine months ended
September 30, 1995. The increase was due primarily to the acquisition of J.R.
Cup on January 20, 1996.
 
  Costs of goods sold increased to $98.5 million or 76.9% of net sales for the
nine months ended September 30, 1996, from $54.1 million or 84.4% of net sales
for the same period in 1995. The decline in cost of goods sold as a percentage
of net sales was due primarily to a decline in raw material prices resulting
from improved market conditions, the increased purchasing power of the
combined company and reductions in manufacturing overhead as a result of the
J.R. Cup Acquisition.
 
  Gross profit increased to $29.5 million or 23.1% of net sales for the nine
months ended September 30, 1996, from $10.0 million or 15.6% of net sales for
the same period in 1995. The increase in gross profit as a percentage of net
sales was due primarily to lower raw material prices and cost reductions
related to the J.R. Cup Acquisition.
 
  Distribution expense increased to $9.6 million or 7.5% of net sales for the
nine months ended September 30, 1996, from $4.3 million or 6.8% of net sales
for the same period in 1995. The increase in distribution expense as a
percentage of net sales was due primarily to rate increases by freight
carriers and a higher percentage of consumer sales, which require greater
delivery costs. The Company also temporarily incurred additional freight costs
as a result of a plant closure and the realignment of customer shipping
locations.
 
  Selling, general and administrative expenses increased to $12.8 million or
10.0% of net sales for the nine months ended September 30, 1996, from $6.5
million or 10.1% of net sales for the same period in 1995. Selling, general
and administrative expenses were constant as a percentage of net sales due
primarily to the cutlery, straws and plastic cup operations which were sold
and reported as discontinued operations in 1995. These allocated expenses were
not eliminated but were absorbed in the remaining business.
 
                                      30
<PAGE>
 
  Income (loss) from operations increased to $6.3 million or 4.9% of net sales
for the nine months ended September 30, 1996, from a loss from operations of
$0.8 million for the same period in 1995. As noted above, during the nine
months ended September 30, 1996, the Company recorded restructuring charges of
$0.9 million, due primarily to a plant closure and the relocation of its
executive offices.
 
  Interest increased to $3.3 million or 2.6% of net sales for the nine months
ended September 30, 1996, from $2.5 million or 3.9% of net sales for the same
period in 1995 due primarily to an increase in borrowings related to the J.R.
Cup Acquisition.
 
  Other expense, net increased to $0.2 million or 0.1% of net sales for the
nine months ended September 30, 1996 from $0.1 million or 0.2% of net sales
for the same period in 1995. The increase in other expenses, net was due
primarily to bank charges.
 
  Income (loss) from continuing operations increased to $2.8 million or 2.2%
of net sales for the nine months ended September 30, 1996, from a loss from
continuing operations of $3.4 million for the same period in 1995, for the
reasons outlined above.
 
 Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
  Net sales increased to $86.2 million in 1995, representing an increase of
$5.3 million or 6.6% over net sales of $80.9 million in 1994. The increase in
net sales was primarily due to increased selling prices announced in the
fourth quarter of 1994 as a result of rising raw material costs experienced by
the industry. Unit volume for 1995 remained constant due primarily to
increases in consumer product sales, offset by a reduction in institutional
sales volume.
 
  Cost of goods sold increased to $75.7 million or 87.8% of net sales in 1995,
from $64.1 million or 79.3% of net sales in 1994. The increase in cost of
goods sold as a percentage of net sales was due primarily to the industry-wide
rise in raw material costs, which began in April 1994 and continued through
August 1995.
 
  Gross profit decreased to $10.6 million or 12.2% of net sales in 1995, from
$16.8 million or 20.7% of net sales in 1994. The decrease in gross profit as a
percentage of net sales was due primarily to the rise in raw material costs,
which was only partially offset by selling price increases during 1995.
 
  Distribution expense increased slightly to $6.0 million or 7.0% of net sales
in 1995, from $5.6 million or 6.9% of net sales in 1994. The increase in
distribution expense as a percentage of net sales for 1995 was due primarily
to slightly higher freight rates incurred in early 1995.
 
  Selling, general and administrative expenses increased to $9.1 million or
10.5% of net sales in 1995, from $8.2 million or 10.1% of net sales in 1994.
The increase in selling, general and administrative expenses as a percentage
of net sales was due primarily to an increase in commissions related to retail
sales.
 
  Income (loss) from operations declined to a loss from operations of $4.5
million in 1995, from income from operations of $3.0 million in 1994. The
reduction in income from operations was due primarily to the increase in raw
material costs, partially offset by an increase in selling prices.
 
  Interest decreased to $2.8 million or 3.3% of net sales in 1995, from $3.0
million or 3.7% of net sales in 1994. The decrease in interest as a percentage
of net sales was due primarily to lower debt levels as a result of a
divestiture in 1995.
 
  Other expense, net was $0.5 million for 1995, as compared to $0.3 million in
1994.
 
  Loss from continuing operations was $7.9 million in 1995, as compared to
$0.3 million in 1994. The increase in the loss from continuing operations
resulted from the industry-wide increase in raw material costs, partially
offset by an increase in selling prices.

<PAGE>
 
 YEAR ENDED DECEMBER 31, 1994 COMPARED TO YEAR ENDED DECEMBER 31, 1993
 
  Net sales decreased to $80.9 million for 1994, representing a decrease of
$2.7 million over net sales of $83.6 million in 1993. The decline in net sales
was due primarily to a decline in sales volume due to the closure of the
Company's Tinton Falls, New Jersey plant in September 1993.
 
  Cost of goods sold decreased to $64.1 million or 79.3% of net sales in 1994,
from $68.5 million or 81.9% of net sales in 1993. The decline in cost of goods
sold as a percentage of net sales was due primarily to the September 1993
closure of the Tinton Falls plant that had higher manufacturing costs as
compared to the Company's other locations.
 
  Gross profit increased to $16.8 million or 20.7% of net sales in 1994, from
$15.1 million or 18.1% of net sales in 1993. The increase in gross profit as a
percentage of net sales was due primarily to the plant closure described
above.
 
  Distribution expense decreased to $5.6 million or 6.9% of net sales in 1994,
from $6.6 million or 7.9% of net sales in 1993. The increase in distribution
expense as a percentage of net sales was due primarily to a realignment of
customers as a result of the plant closure.
 
  Selling, general and administrative expenses decreased to $8.2 million or
10.1% of net sales in 1994, from $10.3 million or 12.4% of net sales in 1993.
The decrease in selling, general and administrative expenses as a percentage
of net sales was due primarily to a reduction in the number of independent
sales representatives and administrative personnel together with related
overhead expenses.
 
  Income (loss) from operations increased to $3.0 million or 3.7% of net sales
in 1994, from a loss from operations of $1.8 million in 1993. The increase in
income from operations was due primarily to lower operating expenses as a
result of staff reductions and lower manufacturing costs.
 
  Interest increased to $3.0 million or 3.7% of net sales in 1994, from $2.5
million or 3.0% of net sales in 1993. The increase in interest as a percentage
of net sales was due primarily to a higher level of borrowings.
 
  Other expense, net was $0.3 million in 1994 related to the sale of a
manufacturing location, compared to $0.4 million in 1993.
 
  Loss from continuing operations was $0.3 million in 1994, as compared to
$4.7 million in 1993, for the reasons outlined above.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  During the years ended December 31, 1993, 1994 and 1995 and the nine months
ended September 30, 1996, the Company's principal sources of funds consisted
of cash from operations and financing sources. For the nine months ended
September 30, 1996, cash provided by operating activities was $4.3 million
compared to cash provided by operating activities of $2.1 million for the same
period in 1995. While net income for the nine months ended September 30, 1996
was $3.5 million compared to a net loss for the same period in 1995 of $4.9
million, working capital increased by $6.3 million in the nine months ended
September 30, 1996, primarily from an increase of accounts receivable and
inventory due to a higher level of sales following the J.R. Cup Acquisition.
The Company has managed its growth in working capital through a combination of
working capital financing, favorable terms from vendors and proceeds of debt
financing for capital expenditures.
 
  As of September 30, 1996, the outstanding balance under the $28.0 million
Revolver was $18.2 million. In connection with the consummation of the
Offering, the Company entered into the Amended Credit Agreement under which
the Existing Credit Agreement was amended and restated primarily to increase
the revolving credit facility to $30.0 million and to include Radnor, WinCup,
SP Acquisition Co.
 
                                      32
<PAGE>
 
and StyroChem International, Inc. as borrowers. See "Description of the
Company's Credit Facilities--The Amended Credit Agreement." Also, in February
1994, the Company's Canadian subsidiary entered into the Canadian Credit
Agreement, certain terms of which have been amended through an annual review
process. The Canadian Credit Agreement consists of a term loan in the
principal amount of $0.7 million Canadian and a revolving credit facility of
up to $2.5 million Canadian. See "Description of the Company's Credit
Facilities--The Canadian Credit Agreement."
 
  The Company's principal uses of cash for the next several years will be
working capital requirements and capital expenditures. The reduction in debt
service requirements resulting from the offering of the Notes and the
amendment of the Credit Agreements will provide the Company with increased
flexibility to make capital expenditures that management believes will provide
an attractive return on investment. Management expects that annual capital
expenditures will increase from historical levels during the next few years as
the Company pursues new development and cost-reduction opportunities.
Management has identified potential capital investment opportunities of
approximately $6.0 million over the next twelve months, in addition to
approximately $2.0 million of non-discretionary capital expenditures
anticipated during such period.
 
  The Company's capital expenditures for the years ended December 31, 1994 and
1995 and the nine months ended September 30, 1996 were $1.6 million, $5.5
million and $2.6 million, respectively. Total capital expenditures increased
in 1995 due to the implementation of the engineering initiatives, which began
in 1994 and are expected to be approximately $5.0 million for 1996.
 
  Management believes that cash generated from operations plus funds from
revolving credit facilities under the Credit Agreements will be sufficient to
meet the Company's expected operating needs, planned capital expenditures and
debt service requirements. However, there can be no assurance that sufficient
funds will be available from operations or borrowings under the Credit
Agreements to meet the Company's cash needs.

                                   BUSINESS
 
GENERAL
 
  The Company is the second largest manufacturer in the U.S. of disposable
foam cup and container products for the foodservice industry, with
approximately a 35% share of this market segment in 1995. The Company
manufactures foam cups for hot and cold drinks, foam bowls and containers and
thermoformed lids, as well as the EPS beads from which such foam products are
manufactured. The Company's 14 highly automated manufacturing facilities
produced 13 billion foam cups, containers and lids and 115 million pounds of
EPS beads in 1995. Through StyroChem, the Company manufactures EPS beads for
its own consumption as well as for third party manufacturers of foam
containers, insulation products and packaging products. The Company believes
that its acquisition of StyroChem, a supplier of EPS beads to the Company
since 1976, will strengthen the Company's competitive position by lowering raw
material costs, improving product quality and enhancing manufacturing
efficiencies. For the nine months ended September 30, 1996, pro forma for the
Acquisitions, the Company had net sales and EBITDA of $172.3 million and $18.6
million, respectively.
 
HISTORY
 
  The Company, through WinCup and J.R. Cup, has been manufacturing foam cups
and containers for more than 30 years. The WinCup foam cup and container
business was established in 1961 and began purchasing EPS beads from StyroChem
when that company began operations in 1976. J.R. Cup's predecessor began
manufacturing foam cups and containers in 1963 and was purchased by James
River in 1986. The Company believes that the consolidation of StyroChem and
J.R. Cup with the Company's foam cup and container operations is a significant
strategic opportunity due to the technological synergies, economies of scale
and broader geographic distribution of the combined businesses.
 
INDUSTRY OVERVIEW
 
  The Company competes primarily within the disposable cup and container
market of the foodservice industry, which includes products manufactured with
paper, plastic, foam and other materials. A recent independent industry survey
estimated that sales of disposable foodservice products were in excess of $7.0
billion in 1994, with sales of disposable cups and containers estimated to
have been more than $2.0 billion. The foam segment of the disposable cup and
container market, which the Company believes had sales of approximately $550.0
million in 1995, is highly concentrated, with the Company and its primary
competitor accounting for more than 80%. The market for other plastic and
paper cups and containers is more fragmented, with at least six different
manufacturers.
 
  The factors that originally gave rise to the use of disposable products
continue to support the market's growth. These include lower labor,
maintenance and energy costs as compared to reusable products, as well as
sanitary considerations and growth in the consumption of take-out foods and
beverages. The expansion of fast-food restaurant chains and the consolidation
of some foodservice distributors into larger companies with a national
presence have also increased the use of disposable products.
 
  In addition to the factors described above, the use of foam cups and
containers has increased significantly over the last two decades due to the
superior insulating qualities of foam and its lower production costs, as
compared to paper. Industry unit shipments of foam cups and containers grew
from 13 billion in 1974 to 28 billion in 1994. The success of foam cups to
date has been primarily in the hot drink cup segment. The Company believes
there is significant growth opportunity in the sale of foam cold drink cups,
particularly the large (16 through 44 ounce) sizes on which the Company makes
higher margins.

  In addition to being used in the manufacture of foam cups and containers,
EPS beads are also used by manufacturers of insulation products and packaging
products. Insulation products are typically used as insulation materials for
roofs, walls and foundations. Packaging products are usually custom molded and
are used to protect products such as computers, electronic consumer products
and appliances from damage while being shipped.
 
COMPETITIVE STRENGTHS
 
  The Company has a strong competitive position in the foam segment of the
disposable cup and container market. The Company attributes its prominent
market position to the following factors:
 
 .  Customer service and quality products. The Company's attention to customer
   service and emphasis on high-quality products allow it to continue to meet
   the needs of its existing customers and attract new ones. Customer service
   is enhanced by the Company's breadth of product offerings, extensive order-
   entry system and strategically located manufacturing facilities. These
   attributes enable the Company to meet the national distribution
   requirements of its customers in an efficient and cost-effective manner.
   The Company also coordinates design efforts with its customers to develop
   new products, such as the new "flare" cup that combines an enhanced
   appearance with a stronger rim construction.
 
 .  Proprietary technology. The Company has developed a broad array of
   proprietary technology that is utilized in various stages of its
   manufacturing operations. Custom-designed and built molding equipment, for
   example, allows the Company to better meet customer requests for
   specialized container designs, custom printing or embossing, as well as to
   maintain high-volume production runs. Other proprietary technology includes
   automated materials handling and auto-case packaging machines. With
   StyroChem, the Company also has the ability to customize EPS bead
   formulations to further enhance manufacturing efficiencies and specific
   product features.
 
 .  Strong customer relationships. Long-term relationships with its customers
   have been an important factor in the Company's success. Of the Company's
   ten largest customers, nine have been purchasing products from the Company
   for more than ten years. The Company works closely with its customers to
   address a variety of needs, including custom product development and
   tooling, seasonal marketing programs and specialized printing requirements.
   The Company believes that the strength of its customer relationships
   results from consistently meeting or exceeding customer expectations.
 
 .  Experienced management team. The Company's management team is highly
   experienced, with a majority of the Company's senior sales, manufacturing,
   administration and engineering executives having spent more than 20 years
   in the foodservice industry. The Company's executive management also has
   extensive experience in managing and integrating acquisitions of businesses
   in various industries, including the foodservice industry.
 
BUSINESS STRATEGY
 
  The Company's business strategy is to increase its revenues and
profitability and to further enhance its market position by emphasizing the
following initiatives:
 
 .  Cost reduction and productivity enhancements. The Company is continuing to
   reduce manufacturing costs by upgrading existing equipment and developing
   new equipment and processes that enhance productivity and improve
   manufacturing quality. The Company's goal is to move toward a just-in-time
   manufacturing process. Production costs have also been and will continue to
   be reduced by eliminating redundant facilities, lowering transportation
   costs and exploiting economies of scale (including raw material pricing)
   provided by the Company's high-volume production. The Company has closed
   several manufacturing and distribution facilities and the Company continues
   to evaluate consolidation opportunities. In addition, the Company has taken
   advantage of its nationwide network of manufacturing facilities to route
   product shipments from the nearest plant, thereby reducing transportation
   costs.
 
                                      35
<PAGE>
 
 .  Integrated manufacturing process. The StyroChem Acquisition will result in
   a more integrated manufacturing process, thereby reducing the Company's
   cost of raw materials and mitigating the impact of raw material price
   fluctuations. Control over EPS bead manufacturing should also provide more
   reliable, consistently high-quality EPS beads, improving the Company's
   overall manufacturing efficiencies. Following the StyroChem Acquisition,
   the Company has continued to purchase a significant amount of its EPS beads
   requirements from Nova Chemicals, Inc. The Company intends to increase over
   time the amount of EPS beads manufactured for its own internal consumption.
 
 .  New markets and improved market position. The Company believes it has a
   significant opportunity to increase its share of the disposable cup and
   container market by positioning foam products, with their superior
   insulating qualities and lower production costs, as an alternative to
   comparable paper products. The Company is developing new products, such as
   the "flare" cup, that will provide potential customers with an attractive
   low-cost alternative to paper cups. In addition, the Company is pursuing
   opportunities to increase sales of its foam products to both current and
   new customers in international markets. In particular, the Company believes
   that there are significant growth opportunities in European and Asian
   markets. Foam cup and container use in these markets is significantly less
   than in the U.S. The Company has had discussions with suppliers and
   customers regarding expansion in these markets.
 
 .  Product development and strategic acquisitions. The Company intends to
   pursue further growth opportunities through the introduction of new and
   enhanced products. In addition, the Company will seek strategic
   acquisitions, joint ventures and alliances that may broaden the Company's
   product lines.
 
PRODUCTS
 
  The Company manufactures a broad range of foam cups, bowls and containers,
foam packaging products and thermoformed plastic lids. The use of foam
provides an insulating feature to the Company's products, allowing them to be
used for both hot and cold beverages and food products while enhancing comfort
for the end user. Foam cups are manufactured in varying sizes (4 to 44 ounces)
for both hot and cold beverages and are sold under the Dixie, COMpac, Profit
Pals, STYROcup, Handi-Kup HK and Simplicity brand names. Foam bowls and other
containers are made in varying sizes (3.5 to 32 ounces) for both hot and cold
food products and are sold under the STYROcontainers brand name. The Company
also manufactures thermoformed leak-resistant plastic lids for its cups, bowls
and containers. These lids feature a "stacking ring" that minimizes the
shifting of a second cup when placed on top of the first cup. Other enhanced
lid features include vents, tear-away tabs and straw slots, depending on the
intended use. Cups, bowls, containers and lids are designed so that the same
lid can be interchanged with many different cup, bowl or container sizes,
which simplifies inventory and display area requirements.
 
  The Company's cups, bowls and containers are available in both smooth and
patterned designs and are available with custom offset or embossed printing.
The Company also manufactures a broad range of custom-designed foam containers
for many of its large national accounts. A significant component of this line
of business is the manufacture of containers for customers such as Nissin Food
Products Co., Ltd., Maruchan, Inc. and Campbell Soup Co., which use the
containers for dried noodle products sold through retail grocery and
supermarket chains. The Company also supplies its products in private label
packaging for certain of its customers.
 
  The Company works continuously with its customers to develop new products.
The recently introduced "flare" cup design, for example, replaces the heavier
rim typically built into the top of a foam cup with a smooth, flared edge that
improves the stability of the cup's construction. Management believes that the
flare cup has been well-received by customers because it combines the
favorable appearance of paper with the insulating qualities of foam.
 
  StyroChem manufactures EPS beads for the Company's internal consumption, in
addition to selling directly to third party manufacturers of foam containers,
insulation products and packaging products.
 
                                      36
<PAGE>
 
StyroChem has been a long-term supplier of EPS beads to the Company. The EPS
beads are categorized by grade, with the highest grade, cup-grade beads, used
to manufacture foam cups and containers. Block-grade and shape-grade beads are
sold to manufacturers of insulation and packaging products, respectively.
 
SALES, MARKETING AND CUSTOMERS
 
  The Company sells its products through a 63-person sales organization and
through an extensive network of more than 50 independent sales
representatives. Sales and marketing efforts are directed by the Company's
Senior Vice President of Sales and Marketing and are supported by 12 senior
sales managers with an average of more than 14 years' experience in the
foodservice industry. The Company believes its experienced sales team and
long-term representative relationships enhance the Company's ability to
provide high levels of customer service and specialized marketing programs,
including custom-designed foam products. Major end users of the Company's
products include fast-food restaurants, full-service restaurants, hospitals,
nursing homes, educational institutions, airlines, business offices, movie
theaters and other leisure time concessionaires, such as sports stadiums.
 
  The Company sells to more than 1,600 national, institutional and retail
accounts throughout the U.S., in Mexico and in other countries. This customer
base, which includes many of the foodservice industry's largest companies, can
be divided into three major categories:
 
 .  National Accounts. National accounts are customers that utilize foam
   products in the sale of their own products and consist primarily of large
   fast-food restaurant chains and convenience stores. During 1995, sales to
   these customers accounted for approximately 14.5% of the Company's net
   sales pro forma for the Acquisitions, and included Perseco Co. (the
   distribution arm for McDonald's Corporation), Fast Food Merchandisers (the
   distribution arm for Hardee's Food Systems, Inc.), Kentucky Fried Chicken
   Corp., Marriott International, Inc., Dunkin' Donuts Incorporated and The
   Southland Corporation.
 
 .  Institutional Accounts. Institutional accounts are customers that purchase
   foam products with a view toward reselling such products in bulk to
   institutional end users, such as hospitals, nursing homes, educational
   institutions, airlines, movie theaters and similar leisure time
   concessionaires, such as sports stadiums. These customers, representing
   approximately 49.7% of the Company's net sales in 1995 pro forma for the
   Acquisitions, are primarily large foodservice distributors and warehouse
   clubs. Companies such as Sysco Corporation, Alliant Foodservice Inc., U.S.
   Foodservice Inc. and Food Services of America have all been customers for
   more than ten years. This group also includes key buying organizations such
   as ComSource Independent Foodservices Cos., Inc. and Affiliated Paper
   Companies, Inc.
 
 .  Retail Accounts. Retail accounts are customers that purchase foam products
   for resale to actual consumers of the products and consist primarily of
   supermarket chains and discount stores. In 1995, retail customers accounted
   for approximately 12.8% of the Company's net sales pro forma for the
   Acquisitions and also included ten of the largest supermarket chains in the
   U.S. Representative customers include Sam's Club Division, WAL-MART Stores,
   Inc., K-Mart Corporation, Kroger Food Stores, Winn-Dixie Stores, Inc., Food
   Lion, Inc. and Albertson's, Inc.
 
  Pro forma for the Acquisitions, no customer represented more than 9.0% of
the Company's net sales for 1995. In addition, the five largest accounts
represented approximately 30.0% of the Company's pro forma net sales for 1995.
 
  Approximately 10% of the Company's foam product sales are made pursuant to
contracts under which product prices are automatically adjusted based on
changes in EPS bead prices. Substantially all of the Company's other foam
product sales are made pursuant to contracts or other arrangements under which
the Company has the right to change product prices on 30 to 60 days' prior
written notice.
 
                                      37

MANUFACTURING
 
  The Company's highly automated manufacturing facilities produced 13 billion
foam cups, containers and lids and 115 million pounds of EPS beads,
respectively, in 1995. The Company's foam products are made with custom-
designed foam cup molding machines, lid production machines and foam cup and
container printing machines. The Company's ten foam plants, located throughout
the U.S., generally operate 24 hours a day, seven days a week and 355 days a
year. StyroChem operates four plants located in the U.S. and Canada that
manufacture EPS beads from styrene monomer.
 
 Manufacturing Process
 
  The manufacture of EPS beads, the primary raw material in the manufacture of
foam products, has two steps: polymerization and impregnation. In the
polymerization phase, styrene monomer, which is a commodity petrochemical
derived primarily from benzene and ethylene, is suspended in water and then
treated with chemicals and catalysts to produce polystyrene crystal in various
sizes, each of which has different end-use applications. To produce EPS beads,
the crystal is impregnated with a high-purity pentane gas.
 
  The Company manufactures its foam cups and containers utilizing a custom
molding process. First, the cup-grade EPS beads are blended with a lubricating
agent and then pre-expanded so that the EPS beads are of the appropriate
density. These pre-expanded EPS beads are then fed through special screeners
to remove undersized and oversized beads. The pre-expanded EPS beads are then
injected into machine molds and fused by injecting steam into the mold cavity.
After the EPS beads are fused, the mold shells are cooled, the mold halves are
opened and the finished cups are ejected. The finished products are vacuum
tested, counted and packaged.
 
  The Company's lid products are produced from high-impact polystyrene
("HIPS"), which is subjected to heat and pressure, after which the product is
extruded through a thin die. The lids are then trimmed for finished goods
packing, while the scrap is ground and reintroduced into the original material
blend. In order to further reduce costs, the Company intends to examine
whether StyroChem can produce HIPS.
 
 Quality Control
 
  The Company's manufacturing quality control program involves random testing
performed at least hourly at each facility for four attributes: seepage,
weight, appearance and strength. A statistical analysis of these test results
is completed and reviewed by the Company. In addition, each machine operator
and packer performs various quality checks during the production process. The
Company also obtains random samples of finished products from its various
manufacturing facilities and performs an analysis similar to that described
above at its Phoenix laboratory.
 
  In addition to the Company's own programs, certain of the Company's larger
customers have established their own product standards and perform periodic
manufacturing audits at the Company's facilities, either through their own
personnel or through an independent testing group such as the American
Institute of Baking.
 
  The Company utilizes its quality, service, manufacturing and customer
partners to enact and follow through on initiatives consistent with total
quality management and good manufacturing practices. Through these programs,
the Company works with its customers to ensure product quality and to create
new products that reflect the present and future needs of its customers.
 
  StyroChem's quality control laboratory includes infrared spectrograph and
atomic absorption units. Laboratory chemists are capable of performing complex
chemical and atomic analysis of styrene monomer, polystyrene crystal,
expandable polystyrene and all other material components of EPS bead
production. This gives StyroChem the ability to customize EPS bead formulas to
meet any special customer requirements. StyroChem's quality control program
includes testing every production batch of EPS beads to ensure it meets
specific customer requirements. Each batch is tested for particle sizes,
pentane gas volume and, if the EPS beads are to be used for insulation, their
fire retardation capability.
 
                                      38
<PAGE>
 
 Engineering
 
  The Company employs more than 40 full-time technical personnel, including 30
full-time engineers and engineering managers, based in the Phoenix, Corte
Madera and Fort Worth facilities. The engineering staff uses computer-aided
design and computer-aided manufacturing systems to design advanced, three-
dimensional models of products and molds. Once an electronic image of the
machine and mold part design is generated, the part can be custom
manufactured. The Company has the capacity to construct all of the proprietary
equipment and machines used in the production, testing and packaging of its
foam products. The Company has also developed and is installing in its
manufacturing facilities automated materials handling equipment which includes
in-line printing, automatic case packaging equipment and more advanced molding
machines.
 
  The Company continually examines how to improve its manufacturing process
efficiencies. Sophisticated infra-red imaging systems, providing real-time
video displays, are used to evaluate the thermal efficiency of molds and
machines under development. The Company also can create special prototype mold
forms for new lid designs and single-cavity cup and container molds, both of
which enhance the Company's ability to evaluate customer design requests
rapidly.
 
RAW MATERIALS
 
  The Company's foam products are manufactured from EPS beads, which are
produced from styrene monomer. Styrene monomer is a commodity petrochemical
that is readily available in bulk quantities from numerous large, vertically
integrated chemical companies. Styrene monomer prices have fluctuated
significantly as a result of changes in petrochemical prices and the capacity,
supply and demand for styrene monomer. For example, the contract price for
styrene monomer ranged from $.23 to $.25 per pound during 1993, rose to $.40
per pound during 1994 and to $.52 per pound during 1995, before decreasing to
$.29 per pound by the end of 1995. During 1996, styrene monomer prices have
ranged from $.27 to $.30 per pound. Styrene monomer purchases during 1995
represented approximately 34% of the Company's cost of goods sold on a pro
forma basis.
 
  The StyroChem Acquisition will not insulate the Company from price
fluctuations for styrene monomer, although it will mitigate the impact of such
fluctuations by increasing the Company's flexibility to purchase styrene
monomer. StyroChem has historically purchased all of its styrene monomer
pursuant to a contract with Chevron. In December 1996, the Company
renegotiated its contract with Chevron, to provide a long-term supply of
styrene monomer with volume discounts. The initial term of the new contract
will extend for seven years. Under the contract, the Company will be required
to purchase the first 120 million pounds of its styrene monomer requirements
per year from Chevron and will have certain rights to purchase additional
styrene monomer.
 
  The Company also has a short-term supply contract for EPS beads with Nova
Chemicals, Inc. This contract provides that the Company has the obligation to
purchase 16 million pounds of EPS beads at a price based upon a styrene
monomer index published in an industry trade journal by an independent third
party. The Company purchases additional amounts of EPS beads from Nova
Chemicals, Inc. on substantially the same terms as this contract.
 
  StyroChem purchases high-purity pentane, which is used as the expanding
agent in the production of EPS beads, from South Hampton Refining Co. and
Ashland Chemical Company. High-purity pentane is available from a limited
number of suppliers. Should high-purity pentane become unavailable, however,
high-purity butane may be substituted as the expanding agent.
 
  The raw materials used by the Company for the manufacture of thermoformed
lids are primarily plastic resins such as HIPS. The Company's HIPS resin
supplies are purchased under agreements with Huntsman Chemical Corp., Chevron,
BASF Corporation and Fina Oil & Chemical Company. Most of the Company's
agreements to purchase HIPS resin contain minimum and maximum purchase
requirements. Furthermore, with the exception of the Company's agreement with
Chevron, the price the Company pays for HIPS resin is determined at the time
of purchase. Most of the plastic resins used by the Company, including HIPS,
are available from a variety of sources.

PROPRIETARY TECHNOLOGY AND TRADEMARKS
 
  The Company has developed a broad array of proprietary technology that is
utilized in various stages of its manufacturing operations. The Company relies
primarily upon confidentiality agreements and restricted plant access to
protect its proprietary technology. The Company does own or hold license
rights with respect to numerous patents relating to its lid design in
manufacturing, embossed cup design and continuous formed foam cup
manufacturing processes. However, the Company does not consider these patents
material to its operations.
 
  The Company holds approximately 30 registered trademarks. The Company does
not consider these trademarks material to its operations.
 
  Pursuant to a license agreement (the "Dixie Agreement"), James River granted
the Company a royalty-free, non-exclusive, non-transferable license to use the
Dixie name on boxes, packaging materials, plastic drinking cups and lids
manufactured by the Company and sold to Sam's Club Division. The Dixie
Agreement terminates on the expiration of a separate Sales Agent Agreement
between the Company and James River concerning sales to Sam's Club Division.
This Sales Agent Agreement, scheduled to expire on January 20, 1997, has been
extended for a new, five-year term in connection with the purchase of James
River's interest in the Joint Venture and will expire on January 20, 2002.
 
  Pursuant to another license agreement, James River granted the Company a
royalty-free, non-exclusive, non-transferable license to use a patent relating
to a beverage container lift tab lid with an accordion hinge.
 
COMPETITION
 
  The Company competes in the highly competitive foodservice industry. The
foam segment of the disposable cup and container market is highly concentrated
and, within this segment, the Company competes principally with Dart, which
has significantly greater financial resources than the Company and controls
the largest share of this market segment. The Company does not believe that
companies operating in related markets are likely to enter the foam segment
due to the significant investment that would be required.
 
  The Company believes that competition within the foam segment of the market
is based primarily on customer service, product quality and the price at which
products are offered. The Company believes that its market position is
attributable to its high level of customer service and product quality,
strategically located manufacturing facilities, proprietary technology and
experienced management team.
 
  The Company also competes with the paper segment, which is more fragmented
than the foam segment. The Company believes that competition between foam and
paper is based on product appearance, quality and price.
 
  StyroChem also competes in a concentrated industry. Management believes that
each of Nova Chemicals, Inc., Huntsman Chemical Corp. and BASF Corporation,
which are larger and have greater financial resources than the Company,
controls a significant share of the market for supplying EPS beads to
manufacturers of insulation and packaging products. The Company believes that
competition within this industry is primarily based on price, although
customer service and support can be a significant competitive factor,
particularly among the smaller manufacturers of foam insulation and packaging
products.
 
ENVIRONMENTAL MATTERS
 
  The Company's facilities are used for manufacturing or warehousing of foam
container products or the EPS beads from which such products are manufactured.
Many of these facilities are subject to federal, state, local and, in one
case, foreign laws and regulations relating to, among other things, emissions
to air, discharges to water and the generation, handling, storage,
transportation and disposal of hazardous and non-hazardous materials and
wastes.
 
                                      40
<PAGE>
 
  Certain of the Company's manufacturing facilities generate air emissions,
including volatile organic compounds and particulate matter, that are
regulated and require permits and/or emissions control equipment. While the
Company believes that the majority of the air emissions from its facilities
are properly permitted and controlled, certain of the Company's facilities
have been cited for instances of noncompliance or have failed to report
certain emissions as required, and it is possible that certain of these
permits do not address all regulated emissions and that certain of the
facilities are not in full compliance with all permit conditions. Although the
Company believes that, based on historical experience, the costs of achieving
and maintaining compliance with laws and regulations regarding air emissions
are unlikely to have a material adverse effect on the Company's financial
condition or operating results, it is possible that the Company could incur
significant fines, penalties or capital costs associated with any confirmed
noncompliance. Furthermore, there can be no assurance that future
environmental laws or regulations, or permit requirements under Title V of the
Clean Air Act, will not require substantial expenditures by the Company or
significant modifications of the Company's operations.
 
  Certain of the Company's manufacturing facilities generate wastewater that
is regulated and requires permits for discharge. While the Company believes
that the majority of the wastewater discharges from its facilities are
properly permitted, certain of the Company's facilities have been cited for
instances of past noncompliance, and it is possible that certain of the
Company's facilities currently lack proper wastewater discharge permits and/or
are not in full compliance with all permit conditions. Although the Company
believes that, based on historical experience, the costs of achieving and
maintaining compliance with laws and regulations regarding wastewater
discharges is unlikely to have a material adverse effect on the Company's
financial condition or operating results, it is possible that the Company
could become subject to significant fines, penalties or capital costs
associated with any confirmed noncompliance. Furthermore, there can be no
assurance that future environmental laws or regulations will not require
substantial expenditures by the Company or significant modifications of the
Company's operations.
 
  The Company generates and handles certain hazardous substances, including
petroleum products, and wastes in connection with its manufacturing processes.
The handling and disposal of these substances and wastes is subject to
federal, state and local regulations, and site contamination originating from
the release or disposal of such substances or wastes can lead to significant
liabilities. It is possible that certain of the Company's current or former
facilities are or were not in full compliance with applicable laws regarding
the handling and disposal of these substances and wastes. The soil and shallow
groundwater at certain of the Company's facilities are known to contain
elevated levels of various contaminants, and the Company is investigating
these conditions to determine whether remedial action is necessary. As such,
the Company may become liable for significant fines or penalties for any
confirmed noncompliance, or for cleanup costs for site contamination. Although
such liability has not had a material adverse effect on the financial
condition or operating results of the Company in the past, and the Company has
no knowledge of claims that could be expected to have a material adverse
effect on its financial condition or operations, there can be no assurance
that the Company will not incur significant costs in connection with
historical on- or off-site handling or disposal of such substances and wastes.
 
  The Company owns and operates underground storage tanks ("USTs") at two of
its facilities for the storage of liquid pentane and diesel fuel. Leak
detection or containment systems are in place at both facilities. One of the
tanks, located at the StyroChem Fort Worth, Texas facility, was recently
pressure tested and no leaks were detected. USTs are generally subject to
federal, state and local laws and regulations that require testing and
upgrading of USTs and remediation of polluted soils and groundwater resulting
from leaking USTs. In addition, if leakage from the Company's UST migrates
onto the property of others, the Company may be subject to civil liability to
third parties for remediation costs or other damages. Based on historical
experience, the Company believes that its liabilities associated with UST
testing, upgrades and remediation are unlikely to have a material adverse
effect on its financial condition or operating results.
 
                                      41
<PAGE>
 
  Certain of the Company's current and former facilities are located in
industrial areas and have been in operation for many years. As a consequence,
it is possible that historical or neighboring activities have affected
properties currently or formerly owned by the Company and that, as a result,
additional environmental issues may arise in the future, the precise nature of
which the Company cannot now predict.
 
  As part of the StyroChem Acquisition, approximately $1.4 million of the
purchase price has been placed in escrow and may be used by the Company to
offset certain expenses associated with specified environmental matters
relating to StyroChem's Texas and Quebec facilities. The categories of
expenses which may be offset with these escrowed funds include consulting
fees, fines and penalties, costs of process changes, costs of changes to and
upgrades, purchases and installation of equipment and/or facilities and any
other capital expenditures for fixed assets, and costs of investigation and
remediation work. The specified environmental matters include matters relating
to compliance with air, wastewater, hazardous and solid waste, and stormwater
permits and laws, as well as matters relating to soil, surface water and
shallow groundwater conditions associated with past operations at StyroChem's
Texas and Quebec facilities and at neighboring properties. However, there can
be no assurance that the escrowed funds will be sufficient to offset all

  The Company's Corte Madera, California facilities are leased by a third
party landlord to James River. In connection with the purchase of James
River's interest in the Joint Venture, the Company and James River entered
into a sublease expiring June 30, 1998 for the Corte Madera facilities. The
Company intends to use reasonable efforts to negotiate a new lease for the
manufacturing and warehouse facilities with the landlord prior to the
expiration of the sublease.
 
  The Company occupies its Baie D'Urfe, Quebec warehouse facility under a
month-to-month sublease that is terminable by either party upon 45 days' prior
notice.
 
  The Company believes that its present facilities are adequate for its
current and projected operations.
 
EMPLOYEES
 
  As of September 30, 1996, Radnor and StyroChem had 1,330 and 148 full-time
employees, respectively. The Company's employees are not represented by any
union. The Company considers its relations with its employees to be good.
 
LEGAL PROCEEDINGS
 
  On November 25, 1996, Jackson National Life Insurance Company ("Jackson")
and Benchmark Holdings, Inc. ("Holdings") filed suit in Cook County, Illinois
Circuit Court against Michael T. Kennedy, Radnor, WinCup, the Joint Venture,
James River and James River Corporation of Virginia. The suit relates to the
November 1995 sale to James River by Holdings of substantially all of
Holdings' assets, consisting of its cutlery and straws operations, and by
WinCup of its plastic cup operations. See Note 1 to the Radnor Financial
Statements. Holdings had issued to Jackson certain shares of nonvoting
preferred stock in connection with the May 1991 acquisition of the cutlery and
straws operations, in which Jackson previously held an unsecured subordinated
debt position.
 
  The suit alleges that, in connection with such sale, (i) certain terms of
the nonvoting preferred stock held by Jackson were breached, (ii) Mr. Kennedy
breached his fiduciary duties to Jackson and Holdings and (iii) Radnor and
certain defendants committed fraud that prevented Jackson from exercising
certain alleged rights as a nonvoting preferred stockholder in a timely manner
so as to prevent the sale from occurring. The suit seeks a broad range of
remedies, including rescission of the November 1995 sale to James River,
payment to Holdings of the profits received by James River and the Joint
Venture since the sale and the Joint Venture's formation, disgorgement of $2.5
million received by certain former key employees of Holdings in consideration
for certain noncompetition covenants, payment by WinCup to Holdings of the $10
million of sale proceeds allocated to the assets sold by WinCup, payment to
Holdings of all funds distributed to WinCup, Radnor and James River in
connection with the formation of the Joint Venture and costs of suit.
Alternatively, the suit seeks actual damages in excess of $30 million and
punitive damages in excess of $10 million, together with costs of suit.
 
  The Company believes that the allegations in the complaint are without
merit. Holdings, through its investment banker, actively solicited a large
number of prospective purchasers regarding the sale of the cutlery and straws
operations. The Company believes that Jackson had no right to prevent the sale
of Holdings' assets. In connection with the sale, Holdings obtained opinions
from independent investment banking firms as to the fairness, from a financial
point of view, of the transaction to Holdings' stockholders and as to the
reasonableness of the negotiated value of the noncompetition agreements. The
proceeds received by Holdings from the sale of the cutlery and straws
operations, together with all remaining assets of Holdings, were significantly
less than the aggregate outstanding indebtedness of Holdings. As a result, no
proceeds were available for distribution to any of Holdings' stockholders,
including Jackson. The Company intends to defend this suit vigorously and does
not believe that the suit will have a material adverse effect on the Company's
financial condition or results of operations.

ordinary course of business, none of which is expected to have a material
adverse effect on the Company's financial condition or results of operations.

LIMITATION OF LIABILITY; INDEMNIFICATION
 
  As permitted by the General Corporation Law of the State of Delaware, the
Company's Certificate of Incorporation provides that directors of the Company
will not be personally liable to the Company or its stockholders for monetary
damages for breach of fiduciary duty as a director, except for liability (i)
for any breach of the director's duty of loyalty to the Company or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) under Section 174
of the General Corporation Law of the State of Delaware, relating to prohibited
dividends, distributions and repurchases or redemptions of stock, or (iv) for
any transaction from which the director derives an improper personal benefit.
However, such limitation of liability would not apply to violations of the
federal securities laws, nor does it limit the availability of non-monetary
relief in any action or proceeding against a director. The Certificate of
Incorporation also includes provisions for indemnification of the Company's
directors and officers to the fullest extent permitted by the General
Corporation Law of the State of Delaware as now or hereafter in effect. Insofar
as indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers or persons controlling the Company pursuant to
the foregoing provisions, the Company has been informed that in the opinion of
the SEC such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable.

                DESCRIPTION OF THE COMPANY'S CREDIT FACILITIES
 
THE AMENDED CREDIT AGREEMENT
 
  On December 5, 1996, the Company entered into an Amended and Restated
Revolving Credit and Security Agreement (the "Amended Credit Agreement") with
The Bank of New York Commercial Corporation, as agent and lender, pursuant to
which the Revolving Credit, Term Loan and Security Agreement dated January 22,
1996 among WinCup, the Joint Venture and the Bank (the "Existing Credit
Agreement") was amended and restated. The Amended Credit Agreement includes
the Company and its U.S. subsidiaries as borrowers.
 
  The Amended Credit Agreement provides for a revolving credit facility in the
aggregate principal amount of up to $30.0 million. Revolving loans under the
Amended Credit Agreement are limited, in the aggregate, to the lesser of the
$30.0 million commitment amount and a "borrowing base" amount less, in each
case, the principal amount of outstanding letters of credit. The borrowing
base may not exceed the sum of: (i) 85% of eligible accounts receivable, plus
(ii) the lesser of $15.0 million or 60% of eligible raw materials and finished
goods inventories of the Company and its U.S. subsidiaries. In addition, there
is a $5.0 million sublimit on standby letters of credit and a $1.0 million
sublimit on documentary letters of credit.
 
  Revolving loans under the Amended Credit Agreement bear interest payable at
the Company's option at a rate not greater than either (i) the sum of 0.25%
plus a rate equal to the greater of (a) Bank of New York's prime rate or (b)
the sum of the federal funds rate plus 0.5% or (ii) the sum of 1.75% plus a
rate equal to the LIBOR rate with respect to the period during which such
interest rate shall be applicable. The revolving loans under the Amended
Credit Agreement will mature on January 22, 2001. In addition, the Amended
Credit Agreement provides for a fee of 0.375% per annum on the undrawn amount
of the credit facility and letter of credit fees of 1.75% and 1.5% of the
aggregate face amount of standby letters of credit and documentary letters of
credit, respectively, under the Amended Credit Agreement. The Amended Credit
Agreement provides for an agency fee, payable annually during the term of the
Amended Credit Agreement, in the amount of $90,000 per year. Under certain
circumstances, if the Company elects to terminate the Amended Credit
Agreement, the Company will incur a prepayment penalty of $1.5 million prior
to January 22, 1997, $1.0 million prior to January 22, 1998 and $500,000 prior
to January 22, 1999.
 
  The Amended Credit Agreement contains certain restrictive covenants that,
among other things, impose limitations upon the Company's ability to merge,
consolidate or dispose of assets; incur liens; make loans and investments;
incur indebtedness; engage in certain transactions with affiliates; incur
certain contingent obligations; pay dividends and other distributions; enter
into lease arrangements; form subsidiaries and make capital expenditures. The
obligations of the Company under the Amended Credit Agreement are secured by a
lien on all of the Company's and its U.S. subsidiaries' inventory, accounts
receivable, general intangibles, trademarks and licenses and the proceeds
thereof.
 
  The Amended Credit Agreement contains events of default customary for
facilities of its type, including without limitation, the Company's failure to
pay principal, interest, fees or other amounts when due; the Company's
material breach of any covenants, representations or warranties; cross-default
and cross-acceleration; change of control of the Company; bankruptcy,
insolvency or similar events involving the Company or its U.S. subsidiaries;
certain adverse events under ERISA plans of the Company or its U.S.
subsidiaries and any of the agreements or liens securing payment of the
obligations under the Amended Credit Agreement ceasing to be enforceable.
 
THE CANADIAN CREDIT AGREEMENT
 
  The Company's Canadian subsidiary has entered into the Agreement Respecting
a Term Loan and other Credit Facilities dated February 25, 1994 between
StyroChem International, Ltd. ("StyroChem Limited") and the Bank of Montreal
(as amended through annual review processes, the "Canadian Credit
 
                                      50
<PAGE>
 
Agreement"). The credit facilities under the Canadian Credit Agreement consist
of the following: (i) a term loan in the principal amount of $0.7 million
Canadian (the "Canadian Term Loan") and (ii) a revolving credit facility with
a borrowing capacity of up to $2.5 million Canadian, that includes a letter of
credit subfacility and a Foreign Exchange Future Contracts subfacility (the
"Canadian Revolver").
 
  Canadian Dollar advances under the Canadian Revolver bear interest at a rate
equal to the Bank of Montreal's prime rate plus 1.0%. U.S. Dollar advances
under the Canadian Revolver bear interest at the Bank of Montreal's U.S. base
rate plus 1.0%. Loans under the Canadian Revolver are payable on demand. The
Canadian Term Loan bears interest at the Bank of Montreal's prime rate plus
1.5% and is payable in equal quarterly installments of $81,250 Canadian
through the last banking day of November 1998. The Canadian Term Loan is
subject to mandatory prepayments in an amount equal to 100% of the net cash
proceeds from the permitted sale or sale/leaseback of any of StyroChem
Limited's fixed assets, to the extent such proceeds are not reinvested in
replacement assets.
 
  The Canadian Credit Agreement contains covenants that, among other things,
impose limitations upon StyroChem Limited's ability to merge, consolidate or
dispose of assets; make loans and investments; incur indebtedness; engage in
certain transactions with affiliates; pay dividends and other distributions;
make capital expenditures and amend certain material contracts to which it is
a party.
 
  The obligations of StyroChem Limited under the Canadian Credit Agreement are
secured by a first priority perfected security interest in all of the material
assets of StyroChem Limited. In addition, SP Acquisition Co. guaranteed the
obligations of StyroChem Limited under the Canadian Credit Agreement up to a
maximum amount of $3.3 million Canadian. SP Acquisition Co. has pledged all of
the issued and outstanding shares of StyroChem Limited as security for its
obligations under its guarantee. Certain long-term advances payable by
StyroChem Limited to SP Acquisition Co. and StyroChem International, Inc. are
subordinated to the obligations of StyroChem Limited under the Canadian Credit
Agreement.
 
  The Canadian Credit Agreement contains customary events of default,
including without limitation, the following: StyroChem Limited's failure to
pay principal, interest, fees or other amounts when due; StyroChem Limited's
violation or material breach of any covenants, representations or warranties;
cross-default and cross-acceleration; change of control of StyroChem Limited;
bankruptcy, insolvency or similar events involving StyroChem Limited;
cessation of StyroChem Limited's business and the levy of certain material
judgments against StyroChem Limited.

                              THE EXCHANGE OFFER
 
TERMS OF THE EXCHANGE OFFER; PERIOD FOR TENDERING OLD NOTES
 
  Upon the terms and subject to the conditions set forth in this Prospectus
and in the accompanying Letter of Transmittal (which together constitute the
Exchange Offer), the Company will accept for exchange Old Notes which are
properly tendered on or prior to the Expiration Date and not withdrawn as
permitted below. As used herein, the term "Expiration Date" means 5:00 p.m.,
Philadelphia time, on     , 1997; provided, however, that if the Company, in
its sole discretion, has extended the period of time during which the Exchange
Offer is open, the term "Expiration Date" means the latest time and date to
which the Exchange Offer is extended.
 
  As of the date of this Prospectus, $100 million aggregate principal amount
of the Old Notes is outstanding. This Prospectus, together with the Letter of
Transmittal, is first being sent on or about      , 1997, to all holders of
Old Notes known to the Company. The Company's obligation to accept Old Notes
for exchange pursuant to the Exchange Offer is subject to certain customary
conditions as set forth under "--Certain Conditions to the Exchange Offer"
below.
 
  The Company expressly reserves the right, at any time or from time to time,
to extend the period of time during which the Exchange Offer is open, and
thereby acceptance for exchange of any Old Notes, by giving oral or written
notice of such extension to the holders thereof as described below. During any
such extension, all Old Notes previously tendered will remain subject to the
Exchange Offer and may be accepted for exchange by the Company. Any Old Notes
not accepted for exchange for any reason will be returned without expense to
the tendering holder thereof as promptly as practicable after the expiration
or termination of the Exchange Offer.
 
  Old Notes tendered in the Exchange Offer must be in denominations of
principal amount of $1,000 or any integral multiple thereof.
 
  The Company expressly reserves the right to amend or terminate the Exchange
Offer, and not to accept for exchange any Old Notes not theretofore accepted
for exchange, upon the occurrence of any of the conditions of the Exchange
Offer specified below under "--Certain Conditions to the Exchange Offer." The
Company will give oral or written notice of any extension, amendment, non-
acceptance or termination to the holders of the Old Notes as promptly as
practicable, such notice in the case of any extension to be issued by means of
a press release or other public announcement no later than 9:00 a.m.,
Philadelphia time, on the next business day after the previously scheduled
Expiration Date.
 
PROCEDURES FOR TENDERING OLD NOTES
 
  Only a registered holder of Old Notes may tender such Old Notes in the
Exchange Offer. The tender to the Company of Old Notes by a holder thereof as
set forth below and the acceptance thereof by the Company will constitute a
binding agreement between the tendering holder and the Company upon the terms
and subject to the conditions set forth in this Prospectus and in the
accompanying Letter of Transmittal. Except as set forth below, a holder who
wishes to tender Old Notes for exchange pursuant to the Exchange Offer must
transmit a properly completed and duly executed Letter of Transmittal,
including all other documents required by such Letter of Transmittal, to First
Union National Bank (the "Exchange Agent") at one of the addresses set forth
below under "Exchange Agent" on or prior to the Expiration Date. In addition,
either (i) certificates for such Old Notes must be received by the Exchange
Agent along with the Letter of Transmittal, (ii) a timely confirmation of a
book-entry transfer ("a Book-Entry Confirmation") of such Old Notes, if such
procedure is available, into the Exchange Agent's account at The Depository
Trust Company (the "Book-Entry Transfer Facility") pursuant to the procedure
for book-entry transfer described below, must be received by the Exchange
Agent prior to the Expiration Date, or (iii) the holder must comply with the
guaranteed delivery procedures described below. THE METHOD OF
 
                                      52
<PAGE>
 
DELIVERY OF OLD NOTES, LETTERS OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS
IS AT THE ELECTION AND RISK OF THE HOLDERS. IF SUCH DELIVERY IS BY MAIL, IT IS
RECOMMENDED THAT REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT
REQUESTED, BE USED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE
TIMELY DELIVERY. NO LETTERS OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO THE
COMPANY.
 
  Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to
tender should contact the registered holder promptly and instruct such
registered holder to tender on such beneficial owner's behalf. If such
beneficial owner wishes to tender on such owner's behalf, such owner must,
prior to completing and executing the Letter of Transmittal and delivering
such owner's Old Notes, either make appropriate arrangements to register
ownership of the Old Notes in such beneficial owner's name or obtain a
properly completed bond power from the registered holder. The transfer of
registered ownership may take considerable time.
 
  Signatures on a Letter of Transmittal or a notice of withdrawal described
below (see "--Withdrawal Rights"), as the case may be, must be guaranteed (see
"--Guaranteed Delivery Procedures") unless the Old Notes surrendered for
exchange pursuant thereto are tendered (i) by a registered holder of the Old
Notes who has not completed the box entitled "Special Issuance Instructions"
or "Special Delivery Instructions" on the Letter of Transmittal or (ii) for
the account of an Eligible Institution (as defined below). In the event that
signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, are required to be guaranteed, such guarantees must be by a financial
institution (including most banks, savings and loan associations and brokerage
houses) that is a participant in the Securities Transfer Agents Medallion
Program, the New York Stock Exchange Medallion Program or the Stock Exchanges
Medallion Program (collectively, "Eligible Institutions"). If Old Notes are
registered in the name of a person other than a signer of the Letter of
Transmittal, the Old Notes surrendered for exchange must be endorsed by or be
accompanied by a written instrument or instruments of transfer or exchange, in
satisfactory form as determined by the Company in its sole discretion, duly
executed by the registered holder exactly as the name or names of the
registered holder or holders appear on the Old Notes with the signature
thereon guaranteed by an Eligible Institution.
 
  All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of Old Notes tendered for exchange will be determined
by the Company in its sole discretion, which determination shall be final and
binding. The Company reserves the absolute right to reject any and all tenders
of any particular Old Notes not properly tendered or not to accept any
particular Old Note which acceptance might, in the judgment of the Company or
its counsel, be unlawful. The Company also reserves the absolute right to
waive any defects or irregularities or conditions of the Exchange Offer as to
any particular Old Notes either before or after the Expiration Date (including
the right to waive the ineligibility of any holder who seeks to tender Old
Notes in the Exchange Offer). The interpretation of the terms and conditions
of the Exchange Offer as to any particular Old Notes either before or after
the Expiration Date (including the Letter of Transmittal and the instructions
thereto) by the Company shall be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of Old Notes
for exchange must be cured within such reasonable period of time as the
Company shall determine. None of the Company, the Exchange Agent or any other
person shall be under any duty to give notification of any defect or
irregularity with respect to any tender of Old Notes for exchange, nor shall
any of them incur any liability for failure to give such notification.
 
  If the Letter of Transmittal or any Old Notes or powers of attorney are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such person should so indicate when signing, and, unless waived by
the Company, proper evidence satisfactory to the Company of their authority to
so act must be submitted with the Letter of Transmittal.
 
 
                                      53
<PAGE>
 
  By tendering, each holder will represent to the Company that, among other
things, the New Notes acquired pursuant to the Exchange Offer are being
obtained in the ordinary course of business of the person receiving such New
Notes, whether or not such person is the holder, and that neither the holder
nor such other person has any arrangement or understanding with any person to
participate in the distribution of the New Notes. If any holder or any such
other person is an "affiliate," as defined under Rule 405 of the Securities
Act, of the Company or is engaged in or intends to engage in, or has an
arrangement or understanding with any person to participate in, a distribution
of such New Notes to be acquired pursuant to the Exchange Offer, such holder
or any such other person (i) may not rely on the applicable interpretation of
the staff of the SEC and (ii) must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction. Each broker-dealer that receives New Notes for its own account in
exchange for Old Notes, where such Old Notes were acquired by such broker-
dealer as a result of market-making activities or other trading activities,
must acknowledge that it will deliver a prospectus in connection with any
resale of such New Notes. See "Plan of Distribution." The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act.
 
ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES
 
  Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
the Company will accept, promptly after the Expiration Date, all Old Notes
properly tendered and will issue the New Notes promptly after acceptance of
the Old Notes. See "--Certain Conditions to the Exchange Offer" below. For
purposes of the Exchange Offer, the Company will be deemed to have accepted
properly tendered Old Notes for exchange when, as and if the Company has given
oral or written notice thereof to the Exchange Agent.
 
  For each Old Note accepted for exchange, the Holder of such Old Note will
receive as set forth below under "Description of the Notes--Book-Entry,
Delivery and Form" a New Note having a principal amount equal to that of the
surrendered Old Note. Accordingly, registered holders of the New Notes on the
relevant record date for the first interest payment date following the
consummation of the Exchange Offer will receive interest accruing from the
most recent date to which interest has been paid on the Old Notes or, if no
interest has been paid, from December 5, 1996. Old Notes accepted for exchange
will cease to accrue interest from and after the date of consummation of the
Exchange Offer. Holders whose Old Notes are accepted for exchange will not
receive any payment in respect of accrued interest on such Old Notes otherwise
payable on any interest payment date the record date for which occurs on or
after consummation of the Exchange Offer. If the Exchange Offer is not
consummated by May 4, 1997, the interest rate borne by the Old Notes shall be
increased by 25 basis points per annum for each 90-day period from and
including May 4, 1997 until but excluding the date of consummation of the
Exchange Offer, up to a maximum aggregate increase of 100 basis points per
annum. Old Notes not tendered or not accepted for exchange will continue to
accrue interest from and after the date of consummation of the Exchange Offer.
 
  In all cases, issuance of New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of certificates for such Old Notes or a timely Book-
Entry Confirmation of such Old Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility, a properly completed and duly executed Letter of
Transmittal and all other required documents. If any tendered Old Notes are
not accepted for any reason set forth in the terms and conditions of the
Exchange Offer or if Old Notes are submitted for a greater principal amount
than the holder desires to exchange, such unaccepted or non-exchanged Old
Notes will be returned without expense to the tendering holder thereof (or, in
the case of Old Notes tendered by book-entry transfer into the Exchange
Agent's account at the Book-Entry Transfer Facility pursuant to the book-entry
procedures described below, such non-exchanged Old Notes will be credited to
an account maintained with such
 
                                      54
<PAGE>
 
Book-Entry Transfer Facility) as promptly as practicable after the expiration
or termination of the Exchange Offer.
 
BOOK-ENTRY TRANSFER
 
  The Exchange Agent will make a request to establish an account with respect
to the Old Notes at the Book-Entry Transfer Facility for purposes of the
Exchange Offer within two business days after the date of this Prospectus, and
any financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of Old Notes by causing the
Book-Entry Transfer Facility to transfer such Old Notes into the Exchange
Agent's account at the Book-Entry Transfer Facility in accordance with such
Book-Entry Transfer Facility's procedures for transfer. However, although
delivery of Old Notes may be effected through book-entry transfer at the Book-
Entry Transfer Facility, the Letter of Transmittal or a facsimile thereof,
with any required signature guarantees and any other required documents, must,
in any case, be transmitted to and received by the Exchange Agent at one of
the addresses set forth below under "--Exchange Agent" on or prior to the
Expiration Date or the guaranteed delivery procedures described below must be
complied with.
 
  DTC's Automated Tender Offer Program ("ATOP") is the only method of
processing exchange offers through DTC. To accept the Exchange Offer through
ATOP, participants in DTC must send electronic instructions to DTC through
DTC's communication system in place of sending a signed, hard copy of the
Letter of Transmittal. DTC is obligated to communicate those electronic
instructions to the Exchange Agent. To tender Old Certificates through ATOP,
the electronic instructions sent to DTC and transmitted by DTC to the Exchange
Agent must contain the character by which the participant acknowledges its
receipt of, agrees to be bound by and confirms the representations, warranties
and other statements made by or deemed to be made by the participant pursuant
to the Letter of Transmittal.
 
GUARANTEED DELIVERY PROCEDURES
 
  If a registered holder of the Old Notes desires to tender such Old Notes and
the Old Notes are not immediately available, or time will not permit such
holder's Old Notes or other required documents to reach the Exchange Agent
before the Expiration Date, or the procedure for book-entry transfer cannot be
completed on a timely basis, a tender may be effected if (i) the tender is
made through an Eligible Institution, (ii) on or prior to 5:00 p.m.,
Philadelphia time, on the Expiration Date, the Exchange Agent receives from
such Eligible Institution a properly completed and duly executed Letter of
Transmittal (or a facsimile thereof) and Notice of Guaranteed Delivery,
substantially in the form provided by the Company (by telegram, telex,
facsimile transmission, mail or hand delivery), setting forth the name and
address of the holder of Old Notes and the amount of Old Notes tendered,
stating that the tender is being made thereby and guaranteeing that within
three New York Stock Exchange ("NYSE") trading days after the date of
execution of the Notice of Guaranteed Delivery, the certificates for all
physically tendered Old Notes, in proper form for transfer, or a Book-Entry
Confirmation, as the case may be, and any other documents required by the
Letter of Transmittal will be deposited by the Eligible Institution with the
Exchange Agent, and (iii) the certificates for all physically tendered Old
Notes, in proper form for transfer, or a Book-Entry Confirmation, as the case
may be, and any other documents required by the Letter of Transmittal will be
deposited by the Eligible Institution within three NYSE trading days after the
date of execution of the Notice of Guaranteed Delivery.
 
WITHDRAWAL RIGHTS
 
  Tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m.,
Philadelphia time, on the Expiration Date. For a withdrawal to be effective, a
written or electronic ATOP transmission (for DTC participants) notice of
withdrawal must be received by the Exchange Agent at one of the addresses set
forth below under "--Exchange Agent." Any such notice of withdrawal must
specify the name of the person being tendered the Old Notes to be withdrawn,
identify the Old Notes to be withdrawn (including
 
                                      55
<PAGE>
 
the principal amount of such Old Notes), and (where certificates for Old Notes
have been transmitted) specify the name in which such Old Notes are registered,
if different from that of the withdrawing holder. If certificates for Old Notes
have been delivered or otherwise identified to the Exchange Agent, then, prior
to the release of such certificates the withdrawing holder must also submit the
serial numbers of the particular certificates to be withdrawn and a signed
notice of withdrawal with signatures guaranteed by an Eligible Institution
unless such holder is an Eligible Institution in which case such guarantee will
not be required. If Old Notes have been tendered pursuant to the procedure for
book-entry transfer described above, any notice of withdrawal must specify the
name and number of the account at the Book-Entry Transfer Facility to be
credited with the withdrawn Old Notes and otherwise comply with the procedures
of such facility. All questions as to the validity, form and eligibility
(including time of receipt) of such notices will be determined by the Company,
whose determination will be final and binding on all parties. Any Old Notes so
withdrawn will be deemed not to have been validly tendered for exchange for
purposes of the Exchange Offer. Any Old Notes which have been tendered for
exchange but which are not exchanged for any reason will be returned to the
holder thereof without cost to such holder (or, in the case of Old Notes
tendered by book-entry transfer into the Exchange Agent's account at the Book-
Entry Transfer Facility pursuant to the book-entry transfer procedures
described above, such Old Notes will be credited to an account maintained with
such Book-Entry Transfer Facility for the Old Notes) as soon as practicable
after withdrawal, rejection of tender or termination of the Exchange Offer.
Properly withdrawn Old Notes may be retendered by following one of the
procedures described under "--Procedures for Tendering Old Notes" above at any
time on or prior to the Expiration Date.
 
CERTAIN CONDITIONS TO THE EXCHANGE OFFER
 
  Notwithstanding any other provisions of the Exchange Offer, and subject to
its obligations pursuant to the Registration Rights Agreement, the Company
shall not be required to accept for exchange, or to issue New Notes in exchange
for, any Old Notes and may terminate or amend the Exchange Offer, if at any
time before the acceptance of such New Notes for exchange, any of the following
event shall occur:
 
    (i) any injunction, order or decree shall have been issued by any court
  or any governmental agency that would prohibit, prevent or otherwise
  materially impair the ability of the Company to proceed with the Exchange
  Offer; or
 
    (ii) the Exchange Offer will violate any applicable law or any applicable
  interpretation of the staff of the SEC.
 
  The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company in whole or in part at any time and from time to time
in its sole discretion. The failure by the Company at any time to exercise any
of the foregoing rights shall not be deemed a waiver of any such right and such
right shall be deemed an ongoing right which may be asserted at any time and
from time to time.
 
  In addition, the Company will not accept for exchange any Old Notes tendered,
and no New Notes will be issued in exchange for any such Old Notes, if at such
time any stop order is threatened by the SEC or in effect with respect to the
Registration Statement of which this Prospectus is a part or the qualification
of the Indenture under the Trust Indenture Act of 1939, as amended.
 
  The Exchange Offer is not conditioned on any minimum principal amount of Old
Notes being tendered for exchange.

  DELIVERY OF THE LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET FORTH
ABOVE OR TRANSMISSION OF INSTRUCTIONS VIA FACSIMILE OTHER THAN AS SET FORTH
ABOVE DOES NOT CONSTITUTE A VALID DELIVERY OF SUCH LETTER OF TRANSMITTAL.
 
FEES AND EXPENSES
 
  The Company will not make any payment to brokers, dealers, or others
soliciting acceptances of the Exchange Offer.
 
  The estimated cash expenses to be incurred in connection with the Exchange
Offer will be paid by the Company and are estimated in the aggregate to be
$150,000.
 
TRANSFER TAXES
 
  Holders who tender their Old Notes for exchange will not be obligated to pay
any transfer taxes in connection therewith, except that holders who instruct
the Company to register New Notes in the name of, or request that Old Notes
not tendered or not accepted in the Exchange Offer be returned to, a person
other than the registered tendering holder will be responsible for the payment
of any applicable transfer tax thereon.
 
CONSEQUENCES OF FAILURE TO EXCHANGE OLD NOTES
 
  Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to the provisions
in the Indenture regarding transfer and exchange of the Old Notes and the
restrictions on transfer of such Old Notes as set forth in the legend thereon
as a consequence of the issuance of the Old Notes pursuant to exemptions from,
or in transactions not subject to, the registration requirements of the
Securities Act and applicable state securities laws. In general, the Old Notes
may not be offered or sold, unless registered under the Securities Act and
applicable state securities laws. The Company does not currently anticipate
that it will register Old Notes under the Securities Act. See " The Exchange
Offer" and "Registration Rights." Based on interpretations by the staff of the
SEC, as set forth in no-action letters issued to third parties, the Company
believes that New Notes issued pursuant to the Exchange Offer in exchange for
Old Notes may be offered for resale, resold or
 
                                      57
<PAGE>
 
otherwise transferred by holders thereof (other than any such holder which is
an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act) without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided that such New Notes are
acquired in the ordinary course or such holders' business and such holders,
other than broker-dealers, have no arrangement or understanding with any person
to participate in the distribution of such New Notes. However, the SEC has not
considered the Exchange Offer in the context of a no-action letter and there
can be no assurance that the staff of the SEC would make a similar
determination with respect to the Exchange Offer as in such other
circumstances. Each holder of the Old Notes who wishes to exchange its Old
Notes for New Notes in the Exchange Offer will be required to make certain
representations to the Company, including that (i) any New Notes to be received
by it will be acquired in the ordinary course of its business, (ii) it has no
arrangement or understanding with any person to participate in a public
distribution (within the meaning of the Securities Act) of the New Notes and
(iii) it is not an "affiliate," as defined in Rule 405 of the Securities Act,
of the Company or the Guarantors, or if it is such an affiliate, that it will
comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable to it. If any holder is an affiliate of
the Company or is engaged in or intends to engage in or has any arrangement or
understanding with respect to the distribution of the New Notes to be acquired
pursuant to the Exchange Offer, such holder (i) may not rely on the applicable
interpretations of the staff of the SEC and (ii) must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. Each broker-dealer that receives New
Notes for its own account in exchange for Old Notes pursuant to the Exchange
Offer must acknowledge that such Old Notes were acquired by such broker-dealer
as a result of market-making activities or other trading activities and that it
will deliver a prospectus in connection with any resale of such New Notes. The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-
dealer in connection with resales of New Notes received in exchange for Old
Notes where such Old Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities. The Company has agreed
that, for a period of 150 days after the date of this Prospectus, it will make
this Prospectus available to any broker-dealer for use in connection with any
such resale. See "Plan of Distribution." In addition, to comply with the
securities laws of certain jurisdictions, if applicable, the New Notes may not
be offered or sold unless they have been registered or qualified for sale in
such jurisdictions or any exemption from registration or qualification is
available and is complied with. The Company has agreed, pursuant to the
Registration Rights Agreement, subject to certain limitations specified
therein, to register or qualify the New Notes for offer or sale under the
securities laws of such jurisdictions as any holder reasonably requests in
writing. Unless a holder so requests, the Company does not currently intend to
register or qualify the sale of the New Notes in any such jurisdictions.

                           DESCRIPTION OF THE NOTES
GENERAL
 
  The Old Notes were issued under an Indenture dated December 5, 1996 (the
"Indenture") among the Company, as issuer, substantially all of the Company's
subsidiaries (collectively, the "Guarantors") and First Union National Bank,
as trustee (the "Trustee"). The terms and conditions of the Notes include
those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (the "Trust Indenture Act") as in
effect on the Issue Date. The Notes are subject to all such terms and
conditions, and reference is made to the Indenture and the Trust Indenture Act
for a statement thereof. The following statements are summaries of the
provisions of the Notes and the Indenture and do not purport to be complete.
Such summaries make use of certain terms defined in the Indenture and are
qualified in their entirety by express reference to the Indenture. Certain of
such defined terms are set forth below under "--Certain Definitions." For
purposes of this "Description of the Notes," the "Company" means Radnor
Holdings Corporation. A copy of the Indenture will be available upon request
to the Company.
 
  The Notes are limited to $100.0 million aggregate principal amount and
issued in fully registered form without coupons in denominations of $1,000 and
any integral multiple of $1,000. In the case of certificated Notes, principal
of, premium, if any, and interest on the Notes are payable, and the Notes are
transferable, at the corporate trust office or agency of the Trustee
maintained for such purposes in Philadelphia, Pennsylvania. Initially, the
Trustee is acting as paying agent and registrar under the Indenture. The
Company may act as paying agent and registrar under the Indenture, and the
Company may change any paying agent and registrar without notice to the
Persons who are registered holders ("Holders") of the Notes. The Company may
pay principal, premium and interest by check and may mail an interest check to
a Holder's registered address. Holders of certificated Notes must surrender
such Notes to the paying agent to collect principal and premium payments. No
service charge will be made for any registration of transfer or exchange of
the Notes, except for any tax or other governmental charge that may be imposed
in connection therewith.
 
PAYMENT TERMS
 
  Interest on the New Notes will accrue from the most recent date to which
interest has been paid on the Old Notes or, if no interest has been paid on
the Old Notes, from December 5, 1996 and will be payable semi-annually on June
1 and December 1 of each year, commencing June 1, 1997, at the rate of 10% per
annum (unless such rate has been temporarily or permanently increased under
the circumstances described in "Registration Rights" below) to holders of the
Notes as of the close of business on the May 15 and November 15 next preceding
the applicable interest payment date. Interest will be computed on the basis
of a 360-day year comprised of twelve 30-day months. The Notes mature on
December 1, 2003.
 
  Payment of the Old Notes is, and payment of the New Notes will be,
guaranteed by the Guarantors, jointly and severally, on a senior basis. See
"--Guarantees."
 
RANKING
 
  The Old Notes are, and the New Notes will be, senior unsecured obligations
of the Company and rank pari passu in right of payment with all other existing
and future senior indebtedness of the Company. The Old Notes are, and the New
Notes will be, effectively subordinated in right of payment to all existing
and future secured indebtedness of the Company and the Company's subsidiaries,
including indebtedness under the Credit Agreements. Loans under the Amended
Credit Agreement are secured by the inventory, accounts receivable, general
intangibles, trademarks and licenses and the proceeds thereof of the Company
and its U.S. subsidiaries. Loans under the Canadian Credit Agreement are
secured by all of the material assets and a pledge of the stock of the
Company's Canadian subsidiary. Pursuant to the
 
                                      59
<PAGE>
 
Indenture governing the Notes, the Company and the Guarantors are permitted,
upon the satisfaction of certain conditions, to incur additional secured
indebtedness or provide guarantees of secured indebtedness. See "Risk
Factors--Ranking of the Notes" and "Description of the Company's Credit
Facilities."
 
  Holders of secured indebtedness of the Company or the Guarantors have claims
with respect to the assets constituting collateral for such indebtedness that
are prior to the claims of Holders of the Notes and the Guarantees,
respectively. In the event of a default on the Notes, or a bankruptcy,
liquidation or reorganization of the Company or the Guarantors, such assets
will be available to satisfy obligations with respect to the indebtedness
secured thereby before any payment therefrom could be made on the Notes or the
Guarantees, as the case may be. To the extent that the value of such
collateral is not sufficient to satisfy the indebtedness secured thereby,
amounts remaining outstanding on such indebtedness would be entitled to share,
together with the indebtedness under the Notes and the Guarantees, as the case
may be, with respect to any other assets of the Company and the Guarantors.
 
GUARANTEES
 
  The Guarantors have, jointly and severally, fully and unconditionally
guaranteed the due and punctual payment of principal of, premium, if any, and
interest on, the Old Notes. The Guarantors will also jointly and severally,
full and unconditionally guarantee the due and punctual payment of principal
of, premium, if any, and interest on the New Notes. The Old Guarantees are,
and the New Guarantees will be, senior unsecured obligations of each
Guarantor, and rank pari passu in right of payment with all other existing and
future senior indebtedness of such Guarantor and senior to all subordinated
indebtedness of such Guarantor. The Old Guarantees are, and the New Guarantees
will be, effectively subordinated in right of payment to all existing and
future secured indebtedness of the Guarantors, including their obligations in
respect of the Credit Agreements.
 
  The Guarantors on the Issue Date included substantially all of the Company's
then existing Subsidiaries and will thereafter include such other Subsidiaries
of the Company that become Guarantors as described under "--Certain
Covenants--Subsidiary Guarantees." The Indenture provides that the obligations
of the Guarantors under their respective Guarantees will be reduced to the
extent necessary to prevent the Guarantees from violating or becoming voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer
or similar laws affecting the rights of creditors generally. See "Risk
Factors--Holding Company Structure; Possible Invalidity of Guarantees."
 
  Upon any sale, exchange, transfer or other disposition, to any Person not an
Affiliate of the Company, of all of the Company's Equity Interest in, or all
or substantially all of the assets of, any Guarantor, which is in compliance
with the Indenture, such Guarantor will be released from all its obligations
under its Guarantee.
 
OPTIONAL REDEMPTION
 
  The Notes are not redeemable at the option of the Company prior to December
1, 2000. On or after that date, the Notes will be redeemable at the option of
the Company, in whole or in part from time to time, on not less than 30 nor
more than 60 days' prior notice, mailed by first-class mail to the Holders'
registered addresses, in cash, at the following redemption prices (expressed
as percentages of the principal amount), if redeemed in the 12-month period
commencing December 1 in the year indicated below, in each case plus accrued
and unpaid interest to the date fixed for redemption:

             ----                                                    ----------

<PAGE>
 
  The Notes are not subject to, or entitled to the benefits of, any sinking
fund.
 
  Notwithstanding the foregoing, at any time on or prior to December 1, 1999,
the Company, at its option, may redeem up to $25.0 million aggregate principal
amount of the Notes from the net proceeds of one or more Public Equity
Offerings by the Company, at a redemption price of 110% of the principal
amount thereof, plus accrued interest to the date of redemption; provided that
at least $75.0 million in aggregate principal amount of the Notes remains
outstanding following such redemption.
 
  Notes may be redeemed or repurchased as set forth below under "--Change of
Control" and "--Certain Covenants--Limitations on Asset Sales" in part in
multiples of $1,000. If less than all the Notes issued under the Indenture are
to be redeemed, the Trustee will select the Notes to be redeemed pro rata, by
lot or by any other method which the Trustee deems fair and appropriate. The
Indenture provides that if any Note is to be redeemed or repurchased in part
only, the notice which relates to the redemption or repurchase of such Note
will state the portion of the principal amount of such Note to be redeemed or
repurchased and will state that on or after the date fixed for redemption or
repurchase a new Note equal to the unredeemed portion thereof will be issued.
 
  On and after the date fixed for redemption or repurchase, interest will
cease to accrue on the Notes or portions thereof called for redemption or
tendered for repurchase.
 
CHANGE OF CONTROL
 
  The Indenture provides that in the event of a Change of Control (the date of
such occurrence being the "Change of Control Date"), the Company will notify
the Holders in writing of such occurrence and will make an irrevocable offer
(the "Change of Control Offer") to purchase on a business day (the "Change of
Control Payment Date") not later than 60 days following the Change of Control
Date, all Notes then outstanding at a purchase price (the "Purchase Price")
equal to 101% of the principal amount thereof plus accrued and unpaid
interest, if any, to the Change of Control Payment Date.
 
  Notice of a Change of Control Offer will be mailed by the Company to the
Holders at their registered addresses not less than 30 days nor more than 60
days before the Change of Control Payment Date. The Change of Control Offer is
required to remain open for at least 20 business days and until 5:00 p.m., New
York City time, on the Change of Control Payment Date. The notice will contain
all instructions and materials necessary to enable Holders to tender (in whole
or in part in a principal amount equal to $1,000 or a whole multiple thereof)
their Notes pursuant to the Change of Control Offer.
 
  The notice, which governs the terms of the Change of Control Offer, will
state: (i) that the Change of Control Offer is being made pursuant to this
covenant as described herein; (ii) the Purchase Price and the Change of
Control Payment Date; (iii) that any Notes not surrendered or accepted for
payment will continue to accrue interest; (iv) that any Notes accepted for
payment pursuant to the Change of Control Offer will cease to accrue interest
after the Change of Control Payment Date; (v) that any Holder electing to have
a Note purchased (in whole or in part) pursuant to a Change of Control Offer
will be required to surrender the Note, with the form entitled "Option of
Holder to Elect Purchase" on the reverse of the Note completed, to the Paying
Agent at the address specified in the notice (or otherwise make effective
delivery of the Note pursuant to book-entry procedures and the related rules
of the applicable depositories) at least five business days before the Change
of Control Payment Date, and (vi) that any Holder will be entitled to withdraw
its election if the Paying Agent receives, not later than three business days
prior to the Change of Control Payment Date, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing its election to have such Note purchased.
 
  On the Change of Control Payment Date, the Company will: (i) accept for
payment the Notes, or portions thereof, surrendered and properly tendered and
not withdrawn, pursuant to the Change of
 
                                      61
<PAGE>
 
Control Offer; (ii) deposit with the Paying Agent money sufficient to pay the
Purchase Price of all the Notes, or portions thereof, so accepted; and (iii)
deliver to the Trustee the Notes so accepted together with an officer's
certificate stating that such Notes have been accepted for payment by the
Company. The Paying Agent will promptly mail or deliver to Holders of Notes so
accepted payment in an amount equal to the Purchase Price. Holders whose Notes
are purchased only in part will be issued new Notes equal in principal amount
to the unpurchased portion of the Notes surrendered.
 
  "Change of Control" is defined in the Indenture to mean the occurrence of
any of the following events: (i) any "person" or "group" (as such terms are
used in Sections 13(d) and 14(d) of the Exchange Act), other than Permitted
Holders (as defined below), is or becomes the "beneficial owner" (as defined
in Rules 13d-3 and 13d-5 under the Exchange Act, except that a Person will be
deemed to have beneficial ownership of all shares that such Person has the
right to acquire, whether such right is exercisable immediately or only after
the passage of time), directly or indirectly, of more than 50% of the voting
power of the total outstanding Voting Stock of the Company voting as one
class; (ii) during any period of two consecutive years, individuals who at the
beginning of such period constituted the Board of Directors of the Company
(together with any new directors whose election to such Board or whose
nomination for election by the stockholders of the Company was approved by a
vote of a majority of the directors then still in office who were either
directors at the beginning of such period or whose election or nomination for
election was previously so approved) for any reason cease to constitute a
majority of such Board of Directors then in office; (iii) the Company
consolidates with or merges with or into any Person or conveys, transfers or
leases all or substantially all of its assets to any Person other than a
wholly-owned Subsidiary (in one transaction or a series of related
transactions), or any corporation consolidates with or merges into or with the
Company, in any such event pursuant to a transaction in which the outstanding
Voting Stock of the Company is changed into or exchanged for cash, securities
or other property, and as a result of such transaction any "person" or
"group," other than Permitted Holders, is or becomes the "beneficial owner"
(as described in clause (i) above) immediately after such transaction,
directly or indirectly, of more than 50% of the voting power of the total
outstanding Voting Stock of the surviving corporation voting as one class; or
(iv) the Company is liquidated or dissolved or adopts a plan of liquidation or
dissolution other than in a transaction which complies with the provisions
described under "--Merger, Consolidation and Sale of Assets."
 
  The Company will comply, to the extent applicable, with the requirements of
Rule 14e-1 under the Exchange Act, any other tender offer rules under the
Exchange Act and other securities laws or regulations in connection with the
offer to repurchase and the repurchase of the Notes as described above.
 
  The Company's ability to repurchase the Notes pursuant to a Change of
Control Offer will be limited by, among other things, the Company's financial
resources at the time of repurchase. There can be no assurance that sufficient
funds will be available at the time of any Change of Control to make any
required repurchases. Furthermore, there can be no assurance that the Company
will be able to fund the repurchase of Notes upon a Change of Control within
the limitations imposed by the terms of other then-existing Senior
Indebtedness. In addition, the terms of the Credit Agreements may limit the
Company's ability to purchase any Notes upon the occurrence of a Change of
Control. In the event a Change of Control occurs at a time when the Company is
prohibited from purchasing Notes, the Company will be required under the
Indenture, within 30 days following a Change of Control to (i) seek the
consent of its lenders to the purchase of the Notes or (ii) refinance the
Indebtedness that prohibits such purchase. If the Company does not obtain such
a consent or refinance such borrowings, the Company will remain prohibited
from repurchasing Notes. The Company's failure to purchase tendered Notes or
make a Change of Control Offer following a Change of Control would constitute
an Event of Default under the Indenture. An amendment of or waiver under the
Indenture may not waive the Company's obligation to make a Change of Control
Offer without the consent of the Holders of at least two-thirds in outstanding
principal amount of the Notes.
 
                                      62
<PAGE>
 
  The existence of the right of Holders to require the Company to repurchase
their Notes upon the occurrence of a Change of Control may deter a third party
from acquiring the Company in a transaction which would constitute a Change of
Control. Subject to certain limitations described below in "--Certain
Covenants," including the limitation on incurrence of additional Indebtedness,
the Company could, in the future, enter into certain transactions, including
acquisitions, refinancings or other recapitalizations, that would not
constitute a Change of Control under the Indenture, but that could increase
the amount of Senior Indebtedness (or any other Indebtedness) outstanding at
such time or otherwise affect the Company's capital structure or credit
ratings. The Change of Control provisions will not prevent a leveraged buyout
led by the Company management, a recapitalization of the Company or a change
in a majority of the members of the Board of Directors of the Company which is
approved by the then-present Board of Directors, as the case may be.
 
  The Indenture provides that the Company will not, and will not permit any of
its Restricted Subsidiaries to, create or permit to exist or become effective
any restriction (other than restrictions not more restrictive than those in
effect under the Credit Agreements or Existing Indebtedness) that would
materially impair the ability of the Company to make a Change of Control Offer
to purchase the Notes or, if such Change of Control Offer is made, to pay for
the Notes tendered for purchase.
 
CERTAIN COVENANTS
 
  The Indenture contains, among others, the following covenants:
 
  Limitations on Indebtedness. The Indenture provides that the Company will
not, and will not permit its Restricted Subsidiaries to, directly or
indirectly, create, incur, issue, assume, guarantee or otherwise become liable
with respect to or become responsible for the payment of, contingently or
otherwise ("incur"), any Indebtedness (including any Acquired Indebtedness);
provided, however, that the Company, or a Restricted Subsidiary of the
Company, may incur Indebtedness if at the time of such incurrence and after
giving pro forma effect thereto, the Company's Interest Coverage Ratio for the
most recently ended four full fiscal quarters for which internal financial
statements are available immediately preceding the date on which such
Indebtedness is incurred, calculated on a pro forma basis as if such
Indebtedness was incurred on the first day of such four full fiscal quarter
period, would be at least 2.0 to 1.0.
 
  The Indenture further provides that notwithstanding the foregoing
limitations, the incurrence of the following will not be prohibited:
 
    (a) Indebtedness of the Company evidenced by the Old Notes and
   Indebtedness of any Guarantor evidenced by the Old Guarantees;
 
    (b) Indebtedness of the Company evidenced by the New Notes and
   Indebtedness of any Guarantor evidenced by the New Guarantees;
 
    (c) Indebtedness of the Company or any Restricted Subsidiary constituting
   Existing Indebtedness and any extension, deferral, renewal, refinancing or
   refunding thereof;
 
    (d) Indebtedness of the Company or any Restricted Subsidiary incurred
   under the Credit Agreements in an aggregate principal amount at any one
   time outstanding not to exceed the greater of (x) $30.0 million and (y) the
   Borrowing Base at the time such Indebtedness was incurred, or any
   refinancing, refunding, deferral, renewal or extension thereof not in
   excess of such amount;
 
    (e) Capitalized Lease Obligations of the Company or any Restricted
   Subsidiary and Indebtedness of the Company or any Restricted Subsidiary
   secured by Liens that secure the payment of all or part of the purchase
   price of assets or property acquired or constructed in the ordinary course
   of business after the Issue Date; provided, however, that the aggregate
   principal amount of such Capitalized Lease Obligations plus such
   Indebtedness of the Company and all of the Restricted Subsidiaries does not
   exceed $3.0 million outstanding at any time;
 
 
                                      63
<PAGE>
 
    (f) Indebtedness of the Company to any Restricted Subsidiary or of any
   Restricted Subsidiary to the Company or another Restricted Subsidiary (but
   only so long as such Indebtedness is held by the Company or a Restricted
   Subsidiary);
 
    (g) Indebtedness in respect of Hedging Obligations; provided, however,
   that the notional principal amount of any such Hedging Obligation does not
   exceed the principal amount of the Indebtedness to which such Hedging
   Obligation relates;
 
    (h) Indebtedness represented by performance, completion, guarantee, surety
   and similar bonds provided by the Company or any Restricted Subsidiary in
   the ordinary course of business consistent with past practice;
 
    (i) In addition to any Indebtedness otherwise permitted to be incurred
   under the Indenture, up to $10.0 million aggregate principal amount of
   Indebtedness at any one time outstanding; and
 
    (j) Any refinancing, refunding, deferral, renewal or extension (each, a
   "Refinancing") of any Indebtedness of the Company or any Restricted
   Subsidiary permitted by the initial paragraph of this covenant (the
   "Refinancing Indebtedness"); provided, however, that (x) such Refinancing
   does not increase the total Consolidated Indebtedness of the Company and
   its Restricted Subsidiaries outstanding at the time of such Refinancing,
   (y) the Refinancing Indebtedness does not provide for any mandatory
   redemption, amortization or sinking fund requirement in an amount greater
   than or at a time prior to the amounts and times specified in the
   Indebtedness being refinanced, refunded, deferred, renewed or extended and
   (z) if the Indebtedness being refinanced, refunded, deferred, renewed or
   extended is subordinated to the Notes, the Refinancing Indebtedness
   incurred to refinance, refund, defer, renew or extend such Indebtedness is
   subordinated in right of payment to the Notes on terms at least as
   favorable to the Holders as those contained in the documentation governing
   the Indebtedness being so refinanced, refunded, deferred, renewed or

  Limitations on Restricted Payments. The Indenture provides that the Company
will not, nor will it cause, permit or suffer any Restricted Subsidiary to,
(i) declare or pay any dividends or make any other distributions (including
through mergers, liquidations or other transactions) on any class of Equity
Interests of the Company or such Restricted Subsidiary (other than dividends
or distributions payable by a wholly-owned Restricted Subsidiary on account of
its Equity Interests held by the Company or another Restricted Subsidiary or
payable in shares of Capital Stock of the Company other than Redeemable
Stock), (ii) make any payment on account of, or set apart money for a sinking
or other analogous fund for, the purchase, redemption or other retirement of
such Equity Interests, (iii) purchase, defease, redeem or otherwise retire any
Indebtedness issued by the Company or any Restricted Subsidiary that is
Subordinated Indebtedness to the Notes, or (iv) make any Restricted
Investment, either directly or indirectly, whether in cash or property or in
obligations of the Company (all of the foregoing being called "Restricted
Payments"), unless, (x) in the case of a dividend, such dividend is payable
not more than 60 days after the date of declaration and (y) after giving
effect to such proposed Restricted Payment, all the conditions set forth in
clauses (1) through (3) below are satisfied (A) at the date of declaration (in
the case of any dividend), (B) at the date of such setting apart (in the case
of any such fund) or (C) on the date of such other payment or distribution (in
the case of any other Restricted Payment) (each such date being referred to as
a "Computation Date"):
 
    (1) no Default or Event of Default has occurred and is continuing or would
   result from the making of such Restricted Payment;
 
    (2) at the Computation Date for such Restricted Payment and after giving
   effect to such Restricted Payment on a pro forma basis, the Company or such
   Restricted Subsidiary could incur $1.00 of additional Indebtedness pursuant
   to the covenant described in the initial paragraph under "--Limitations on
   Indebtedness;" and
 
                                      64
<PAGE>
 
    (3) the aggregate amount of Restricted Payments declared, paid or
   distributed subsequent to the Issue Date (including the proposed Restricted
   Payment) does not exceed the sum of (i) 50% of the cumulative Consolidated
   Net Income of the Company for the period (taken as one accounting period)
   commencing on the first day of the first full quarter after the Issue Date
   to and including the last day of the Company's last fiscal quarter ending
   prior to the Computation Date (each such period to constitute a
   "Computation Period") (or, in the event Consolidated Net Income of the
   Company during the Computation Period is a deficit, then minus 100% of such
   deficit), (ii) the aggregate Net Cash Proceeds of the issuance or sale or
   the exercise (other than to a Subsidiary or an employee stock ownership
   plan or other trust established by the Company or any of its Subsidiaries
   for the benefit of their employees) of the Company's Equity Interests
   (other than Redeemable Stock) subsequent to the Issue Date, and (iii) $3.0
   million.
 
  If no Default or Event of Default has occurred and is continuing or would
occur as a result thereof, the prohibitions set forth above are subject to the
following exceptions: (a) Restricted Investments acquired by the Company in
connection with any Asset Sale consummated in accordance with the covenant
described under "--Limitations on Asset Sales" to the extent such Investments
are permitted under such covenant, provided, however, that such Restricted
Investments will be excluded in the calculation of the amount of Restricted
Payments previously made for purposes of clause (3) of the preceding
paragraph; (b) any purchase or redemption of Equity Interests or Subordinated
Indebtedness made by exchange for, or out of the proceeds of the substantially
concurrent sale of, Equity Interests of the Company (other than Redeemable
Stock and other than Equity Interests issued or sold to a Subsidiary or an
employee stock ownership plan), provided, however, that (x) such purchase or
redemption will be excluded in the calculation of the amount of Restricted
Payments previously made for purposes of clause (3) of the preceding paragraph
and (y) the Net Cash Proceeds from such sale will be excluded for purposes of
clause 3(ii) of the preceding paragraph to the extent utilized for purposes of
such purchase or redemption; (c) any purchase or redemption of Subordinated
Indebtedness of the Company made by exchange for, or out of the proceeds of
the substantially concurrent sale of, Subordinated Indebtedness of the Company
or any Restricted Subsidiary which is permitted to be issued pursuant to the
provisions of the covenant described under "--Limitation on Indebtedness,"
provided, however, that such purchase or redemption will be excluded in the
calculation of the amount of Restricted Payments previously made for purposes
of clause (3) of the preceding paragraph; (d) the purchase of Capital Stock
held by employees of the Company or any Subsidiary pursuant to any employee
stock ownership plan thereof upon the termination, retirement or death of any
such employee in accordance with the provisions of any such plan in an amount
not greater than $500,000 in any calendar year, provided, however, that any
such purchase will be included in the calculation of the amount of Restricted
Payments previously made for purposes of clause (3) of the preceding
paragraph; and (e) Investments described in clause (vi) of the definition of
Permitted Investments, provided, however, that such Investments will be
included in the calculation of the amount of Restricted Payments previously
made for purposes of clause (3) of the preceding paragraph.
 
  For purposes of this covenant, (a) the amount of any Restricted Payment
declared, paid or distributed in property of the Company or any Restricted
Subsidiary will be deemed to be the net book value of any such property that
is intangible property and the Fair Market Value (as determined in good faith
by and set forth in a resolution of the Board of Directors) of any such
property that is tangible property at the Computation Date, in each case,
after deducting related reserves for depreciation, depletion and amortization;
(b) the amount of any Restricted Payment declared, paid or distributed in
obligations of the Company or any Restricted Subsidiary will be deemed to be
the principal amount of such obligations as of the date of the adoption of a
resolution by the Board of Directors or such Restricted Subsidiary authorizing
such Restricted Payment; and (c) a distribution to holders of the Company's
Equity Interests of (i) shares of Capital Stock or other Equity Interests of
any Restricted Subsidiary of the Company or (ii) other assets of the Company,
without, in either case, the receipt of equivalent consideration therefor will
be regarded as the equivalent of a cash dividend equal to the excess of the
Fair Market Value of the Equity Interests or other assets being so distributed
at the time of such distribution over the consideration, if any, received
therefor.

  Limitations on Liens. The Indenture provides that the Company will not, and
will not permit any Restricted Subsidiary to, create, incur, assume or suffer
to exist any Lien upon any of their respective assets or properties now owned
or acquired after the Issue Date, or any income or profits therefrom, unless
the Notes are directly secured equally and ratably (or prior to in the case of
Liens with respect to Indebtedness subordinated to the Notes or the
Guarantees, as the case may be), excluding, however, from the operation of the

   existence on the Issue Date, including the Credit Agreements;
 
    (b) Permitted Liens;
 
    (c) Liens on assets or properties of the Company, or on assets or
   properties of Restricted Subsidiaries, to secure the payment of all or a
   part of the purchase price of assets or property acquired or constructed
   after the Issue Date; provided, however, that (i) the aggregate principal
   amount of Indebtedness secured by such Liens does not exceed the original
   cost or purchase price of the assets or property so acquired or
   constructed, (ii) the Indebtedness secured by such Liens is otherwise
   permitted to be incurred under the Indenture and (iii) such Liens do not
   encumber any other assets or property of the Company or any Restricted
   Subsidiary and the Indebtedness secured by the Lien may not be created more
   than 90 days after the later of the acquisition, completion of
   construction, repair, improvement, addition or commencement of full
   operation of the property subject to the Lien;
 
    (d) Liens on the assets or property acquired by the Company or any
   Restricted Subsidiary after the Issue Date; provided, however, that (i)
   such Liens existed on the date such asset or property was acquired and were
   not incurred as a result of or in anticipation of such acquisition and (ii)
   such Liens do not extend to or cover any property or assets of the Company
   or any Restricted Subsidiary other than the property or assets so acquired;
 
    (e) Liens securing Indebtedness which is incurred to refinance
   Indebtedness which has been secured by a Lien permitted under the Indenture
   and which is permitted to be refinanced under the Indenture; provided,
   however, that such Liens do not extend to or cover any property or assets
   of the Company or any Restricted Subsidiary not securing the Indebtedness
   so refinanced;
 
    (f) Liens on assets or property of the Company or any Restricted
   Subsidiary that is subject to a Sale and Leaseback Transaction, provided,
   that the aggregate principal amount of Attributable Indebtedness in respect
   of all Sale and Leaseback Transactions then outstanding does not at the
   time such a Lien is incurred exceed $5.0 million;
 
    (g) Liens on property or shares of Capital Stock of a Person at the time
   such Person becomes a Restricted Subsidiary; provided, however, that such
   Liens are not created, incurred or assumed in contemplation of the
   acquisition thereof by the Company or a Subsidiary; provided further, that
   such Liens may not extend to any other property owned by the Company or a
   Restricted Subsidiary;
 
    (h) Liens securing Indebtedness of a Restricted Subsidiary owing to the
   Company or a wholly-owned Restricted Subsidiary;
 
    (i) Liens on inventory, accounts receivable, general intangibles,
   trademarks and licenses and the proceeds thereof of the Company or any
   Restricted Subsidiary securing the obligations under clause (d) of the
   covenant described under "--Limitations on Indebtedness;" and
 
    (j) Liens securing Indebtedness in respect of Hedging Obligations
   permitted to be incurred pursuant to the provisions of the covenant
   described under "--Limitations on Indebtedness."
 
  Limitations on Payment Restrictions Affecting Restricted Subsidiaries. The
Indenture provides that the Company will not, and will not permit any
Restricted Subsidiary to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any consensual encumbrance or restriction
of any kind on the ability of any Restricted Subsidiary to (i) pay dividends
or make any other distribution to the Company or its Restricted Subsidiaries
on its Equity Interests, (ii) pay any Indebtedness owed to the Company or any
other Restricted Subsidiary, (iii) make loans or advances to the Company or
any other
 
                                      66
<PAGE>
 
Restricted Subsidiary or (iv) transfer any of its property or assets to the
Company or any other Restricted Subsidiary, except (A) consensual encumbrances
or restrictions contained in or created pursuant to the Credit Agreements and
other Existing Indebtedness listed on a schedule to the Indenture, (B)
consensual encumbrances or restrictions in the Notes and the Indenture, (C)
any restriction, with respect to a Restricted Subsidiary of the Company that
is not a Subsidiary of the Company on the Issue Date, in existence at the time
such entity becomes a Restricted Subsidiary of the Company and not created as
a result of or in anticipation of such entity becoming a Restricted Subsidiary
of the Company; provided that such encumbrance or restriction is not created
in anticipation of or in connection with such entity becoming a Subsidiary of
the Company and is not applicable to any Person or the properties or assets of
any Person other than a Person that becomes a Subsidiary, (D) any encumbrances
or restrictions pursuant to an agreement effecting a refinancing of
Indebtedness referred to in clauses (A) or (C) of this covenant or contained
in any amendment to any agreement creating such Indebtedness, provided that
the encumbrances and restrictions contained in any such refinancing or
amendment are not more restrictive taken as a whole (as determined in good
faith by the chief financial officer of the Company) than those provided for
in such Indebtedness being refinanced or amended, (E) encumbrances or
restrictions contained in any other Indebtedness permitted to be incurred
subsequent to the Issue Date pursuant to the provisions of the covenant
described under "--Limitations on Indebtedness", provided that any such
encumbrances or restrictions are not more restrictive taken as a whole (as
determined in good faith by the chief financial officer of the Company) than
the most restrictive of those provided for in the Indebtedness referred to in
clauses (A) or (C) of this covenant, (F) any such encumbrance or restriction
consisting of customary nonassignment provisions in leases governing leasehold
interests to the extent such provisions restrict the transfer of the lease,
(G) any restriction with respect to a Restricted Subsidiary imposed pursuant
to an agreement entered into for the sale or disposition of all or
substantially all of the Capital Stock or assets of such Restricted Subsidiary
in compliance with the Indenture pending the closing of such sale or
disposition, provided that such restrictions apply solely to the Capital Stock
or assets of such Restricted Subsidiary which are being sold; or (H) any
encumbrance or restriction due to applicable law.
 
  Limitations on Asset Sales. The Indenture provides that the Company will
not, and will not permit any Restricted Subsidiary to, make any Asset Sale
(other than to the Company or another Restricted Subsidiary) unless (i) the
Company or such Restricted Subsidiary receives consideration at the time of
such Asset Sale at least equal to the Fair Market Value of the assets sold or
otherwise disposed of, and at least 85% of the consideration received by the
Company or such Restricted Subsidiary from such Asset Sale is in the form of
cash or Cash Equivalents and (ii) the Net Proceeds received by the Company or
such Restricted Subsidiary from such Asset Sale are applied in accordance with
the following paragraphs.
 
  If all or a portion of the Net Proceeds of any Asset Sale are not required
to be applied to repay permanently any Senior Indebtedness of the Company then
outstanding as required by the terms thereof, or the Company determines not to
apply such Net Proceeds to the permanent prepayment of any Senior Indebtedness
outstanding or if no such Senior Indebtedness is then outstanding, then the
Company may within 180 days of the Asset Sale, invest the Net Proceeds in the
Company or one or more Restricted Subsidiaries. The amount of such Net
Proceeds neither used to permanently repay or prepay Senior Indebtedness nor
used or invested as set forth in this paragraph constitutes "Excess Proceeds."
 
  When the aggregate amount of Excess Proceeds from one or more Asset Sales
equals $5.0 million or more, the Company will apply 100% of such Excess
Proceeds within 180 days subsequent to the consummation of the Asset Sale
which resulted in the Excess Proceeds equaling $5.0 million or more to the
purchase of Notes tendered to the Company for purchase at a price equal to
100% of the principal amount thereof, plus accrued interest, if any, to the
date of purchase pursuant to an offer to purchase made by the Company (an
"Asset Sale Offer") with respect to the Notes. Any Asset Sale Offer may
include a pro rata offer under similar circumstances to purchase other Senior
Indebtedness requiring a similar offer. Any Asset Sale Offer will be made
substantially in accordance with the procedures for a Change of
 
                                      67
<PAGE>
 
Control Offer described under "--Change of Control." Until such time as the
Net Proceeds from any Asset Sale are applied in accordance with this covenant,
such Net Proceeds will be segregated from the other assets of the Company and
the Subsidiaries and invested in cash or Cash Equivalents, except that the
Company or any Restricted Subsidiary may use any Net Proceeds pending the
utilization thereof in the manner (and within the time period) described
above, to repay revolving loans (under the Credit Agreements or otherwise)
without a permanent reduction of the commitment thereunder.
 
  The Company will cause a notice of any Asset Sale Offer to be mailed to the
Holders at their registered addresses not less than 30 days nor more than 60
days before the purchase date. Such notice will contain all instructions and
materials necessary to enable Holders to tender their Notes to the Company.
Upon receiving notice of an Asset Sale Offer, Holders may elect to tender
their Notes in whole or in part in integral multiples of $1,000 in exchange
for cash. To the extent that Holders properly tender Notes in an amount
exceeding the Asset Sale Offer, Notes of tendering Holders will be repurchased
on a pro rata basis (based on amounts tendered).
 
  The Credit Agreements and any future credit agreements to which the Company
becomes a party may restrict the Company's ability to repurchase the Notes
pursuant to an Asset Sale Offer. In the event the Company is required to make
an Asset Sale Offer at a time when the Company is prohibited from making such
Offer, the Company will be required under the Indenture, on or prior to the
date that the Company is required to make an Asset Sale Offer, to (i) seek the
consent of its lenders to repurchase Notes pursuant to such Asset Sale Offer
or (ii) refinance the Indebtedness that prohibits such Asset Sale Offer. If
the Company does not obtain such a consent or refinance such borrowings, the
Company will remain prohibited from making such Offer. The Company's failure
to purchase Notes pursuant to an Asset Sale Offer or make such Asset Sale
Offer would constitute an Event of Default under the Indenture.
 
  The Company will comply, to the extent applicable, with the requirements of
Rule 14e-1 under the Exchange Act, any other tender offer rules under the
Exchange Act and other securities laws or regulations in connection with any
offer to repurchase and the repurchase of the Notes as described above.
 
  The Company will not, and will not permit any of its Restricted Subsidiaries
to, create or permit to exist or become effective any restriction (other than
restrictions not more restrictive than those in effect under the Credit
Agreements or Existing Indebtedness) that would materially impair the ability
of the Company to comply with the provisions of this "Limitations on Asset
Sales" covenant.
 
  Limitations on Sale and Leaseback Transactions. The Indenture provides that
the Company will not, and will not permit any Restricted Subsidiary to, enter
into any Sale and Leaseback Transaction unless (i) at the time of the
occurrence of such transaction and after giving effect to such transaction and
(x) in the case of a Sale and Leaseback Transaction which is a Capitalized
Lease Obligation, giving effect to the Indebtedness in respect thereof, and
(y) in the case of any other Sale and Leaseback Transaction, giving effect to
the Attributable Indebtedness in respect thereof, the Company or such
Restricted Subsidiary could incur $1.00 of additional Indebtedness pursuant to
the covenant described in the initial paragraph under "--Limitations on
Indebtedness," (ii) at the time of the occurrence of such transaction, the
Company or such Restricted Subsidiary could incur Indebtedness secured by a
Lien on property in a principal amount equal to or exceeding the Attributable
Indebtedness in respect of such Sale and Leaseback Transaction pursuant to the
covenant described under "--Limitations on Liens", and (iii) the transfer of
assets in such Sale and Leaseback Transaction is permitted by, and the Company
applies the proceeds of such transaction in compliance with, the covenant
described under "--Limitations on Asset Sales."
 
  Limitations on Mergers; Sales of Assets. The Indenture provides that the
Company will not consolidate with or merge into, or sell, assign, convey,
lease or transfer all or substantially all of its assets and those of its
Subsidiaries taken as a whole to, any Person, unless (i) the resulting,
surviving or transferee Person expressly assumes all the obligations of the
Company under the Notes and the Indenture; (ii) such
 
                                      68
<PAGE>
 
Person is organized and existing under the laws of the United States of
America, a state thereof or the District of Columbia; (iii) at the time of the
occurrence of such transaction and after giving effect to such transaction on
a pro forma basis, such Person could incur $1.00 of additional Indebtedness
pursuant to the covenant described in the initial paragraph under "--
Limitations on Indebtedness"; (iv) at the time of the occurrence of such
transaction and after giving effect to such transaction on a pro forma basis,
the Consolidated Net Worth of such Person is equal to or greater than the
Consolidated Net Worth of the Company immediately prior to such transaction;
(v) each Guarantor, to the extent applicable, will by supplemental indenture
confirm that its Guarantee will apply to such Person's obligations under the
Notes; and (vi) immediately before and immediately after giving effect to such
transaction and treating any Indebtedness which becomes an obligation of the
Company or any of its Subsidiaries or of such Person as a result of such
transaction as having been incurred by the Company or such Subsidiary or such
Person, as the case may be, at the time of such transaction, no Default or
Event of Default has occurred and is continuing.
 
  The Indenture provides that no Guarantor will, and the Company will not
permit a Guarantor to, in a single transaction or series of related
transactions merge or consolidate with or into any other corporation (other
than the Company or any other Guarantor) or other entity, or sell, assign,
convey, transfer, lease or otherwise dispose of all or substantially all of
its properties and assets to any entity (other than the Company or any other
Guarantors) unless at the time and giving effect thereto: (i) either (1) such
Guarantor is the continuing corporation or (2) the entity (if other than such
Guarantor) formed by such consolidation or into which such Guarantor is merged
or the entity which acquires by sale, assignment, conveyance, transfer, lease
or disposition the properties and assets of such Guarantor is a corporation
duly organized and validly existing under the laws of the United States of
America, any state thereof or the District of Columbia and expressly assumes
by a supplemental indenture, executed and delivered to the Trustee, in a form
reasonably satisfactory to the Trustee, all the obligations of such Guarantor
under the Notes and the Indenture; and (ii) immediately before and immediately
after giving effect to such transaction, no Default or Event of Default has
occurred and is continuing. The provisions of this paragraph will not apply to
any transaction (including any Asset Sale made in accordance with "--
Limitations on Asset Sales" above) with respect to any Guarantor if the
Guarantee of such Guarantor is released in connection with such transaction in
accordance with the applicable provisions of the Indenture. Upon any sale,
exchange, transfer or other disposition, to any Person not an Affiliate of the
Company, of all of the Company's or a Restricted Subsidiary's Equity Interests
in, or all or substantially all of the assets of, any Guarantor, which is in
compliance with the Indenture, such Guarantor will be released from all its
obligations under its Guarantee.
 
  In the event of any transaction (other than a lease) described in and
complying with the conditions listed in the immediately preceding paragraphs
in which the Company or any Guarantor is not the continuing corporation, the
successor Person formed or remaining will succeed to, and be substituted for,
and may exercise every right and power of, the Company or such Guarantor, as
the case may be, and the Company or such Guarantor, as the case may be, would
be discharged from its obligations under the Indenture, the Notes or its
Guarantee, as the case may be.
 
  Subsidiary Guarantees. The Indenture provides that if (i) any Subsidiary of
the Company becomes a Restricted Subsidiary after the Issue Date, (ii) the
Company or any Subsidiary of the Company that is a Guarantor transfers or
causes to be transferred, in one transaction or a series of related
transactions, property or assets (including, without limitation, businesses,
divisions, real property, assets or equipment) which in the aggregate have a
value equal to or greater than 15% of the Company's total assets determined on
a consolidated basis as of the time of transfer to any Subsidiary or
Subsidiaries of the Company that is not a Guarantor or are not Guarantors, or
(iii) any Subsidiary of the Company which has a value equal to or greater than
5% of the Company's total assets determined on a consolidated basis as of the
time of determination directly or indirectly guarantees or otherwise becomes
obligated with respect to any Senior Indebtedness of the Company, the Company
will cause such Subsidiary or Subsidiaries to execute and
 
                                      69
<PAGE>
 
deliver to the Trustee a supplemental indenture pursuant to which such
Subsidiary or Subsidiaries will unconditionally guarantee all of the Company's
obligations under the Indenture and the Notes on the same terms as the other
Guarantors, which Guarantee will rank pari passu with any Senior Indebtedness
of such Subsidiary. See "--Guarantees". The provisions of clauses (ii) and
(iii) of this paragraph will not apply to any transaction permitted by the
covenant described under "--Limitations on Asset Sales" above.
 
  Transactions with Affiliates. The Indenture provides that the Company and
its Restricted Subsidiaries will not, directly or indirectly, enter into any
transaction or series of related transactions with or for the benefit of any
of their respective Affiliates other than with the Company or any Restricted
Subsidiaries, except on an arm's-length basis and if (x)(i) in the case of any
such transaction in which the aggregate remuneration, rental value or other
consideration (including the value of a loan), together with the aggregate
remuneration, rental value or other consideration (including the value of a
loan) of all such other transactions consummated in the year during which such
transaction is proposed to be consummated, exceeds $500,000, the Company
delivers board resolutions to the Trustee evidencing that the Board of
Directors and the Independent Directors that are disinterested each have (by a
majority vote) determined in good faith that such transaction is in the best
interests of the Company and that the aggregate remuneration, rental value or
other consideration (including the value of any loan) inuring to the benefit
of such affiliate from any such transaction is not greater than that which
would be charged to or extended by the Company or its Subsidiaries, as the
case may be, on an arm's-length basis for similar properties, assets, rights,
goods or services by or to a Person not affiliated with the Company or its
Subsidiaries, as the case may be, and (ii) in the case of any such transaction
in which the aggregate remuneration, rental value or other consideration
(including the value of any loan), together with the aggregate remuneration,
rental value or other consideration (including the value of any loan) of all
such other transactions consummated in the year during which such transactions
are proposed to be consummated, exceeds $2.5 million, in addition to the
requirements set forth in clause (x)(i) above, the Company delivers to the
Trustee an opinion evidencing that a nationally recognized investment banking
firm, unaffiliated with the Company and the Affiliate which is party to such
transaction, has determined that the aggregate remuneration, rental value or
other consideration (including the value of a loan) inuring to the benefit of
such Affiliate from any such transaction is not greater than that which would
be charged to or extended by the Company or its Subsidiaries, as the case may
be, on an arm's-length basis for similar properties, assets, rights, goods or
services by or to a Person not affiliated with the Company or its
Subsidiaries, as the case may be, and (y) all such transactions referred to in
clauses x(i) and (ii) are entered into in good faith. Any transaction required
to be approved by Independent Directors pursuant to the preceding paragraph
must be approved by at least one such Independent Director.
 
  The provisions of the preceding paragraph do not prohibit (i) any Restricted
Payment permitted to be paid pursuant to the provisions of the covenant
described under "--Limitations on Restricted Payments", (ii) any issuance of
securities, or other payments, awards or grants in cash, securities or
otherwise pursuant to, or the funding of, employment arrangements, stock
options and stock ownership plans approved by the Board of Directors, (iii)
loans or advances to employees in the ordinary course of business consistent
with past practices, not to exceed $500,000 aggregate principal amount
outstanding at any time, and (iv) the payment of fees and compensation to, and
indemnity provided on behalf of, officers, directors, employees or consultants
of the Company or any of its Subsidiaries, as determined by the Board of
Directors in good faith and as paid or provided pursuant to agreements or
arrangements entered into in the ordinary course of business.
 
  Limitation on Issuances and Sales of Capital Stock of Restricted
Subsidiaries. The Indenture provides that the Company (i) will not, and will
not permit any Restricted Subsidiary to, transfer, convey, sell, lease or
otherwise dispose of any Capital Stock of any Restricted Subsidiary to any
person other than the Company or a wholly-owned Restricted Subsidiary, unless
(a) such transfer, conveyance, sale, lease or other disposition is of all the
Capital Stock of such Restricted Subsidiary and (b) the cash Net Proceeds from
such transfer, conveyance, sale, lease or other disposition are applied in
accordance with the
covenant "--Limitation on Asset Sales" covenant, and (ii) will not permit any
Restricted Subsidiary to issue
 
                                      70
<PAGE>
 
any of its Capital Stock (other than directors' qualifying shares) to any
Person other than to the Company or a wholly-owned Restricted Subsidiary.
 
  Limitations on Investments. The Indenture provides that the Company will not,
and will not permit any Restricted Subsidiaries, directly or indirectly, to
make any Investment after the Issue Date, other than (i) Permitted Investments
and (ii) Restricted Investments to the extent permitted pursuant to the
covenant described under "--Limitations on Restricted Payments."
 
  Provision of Financial Statements. The Indenture provides that, whether or
not the Company is subject to Section 13(a) or 15(d) of the Exchange Act, the
Company will, to the extent permitted under the Exchange Act, file with the SEC
the annual reports, quarterly reports and other documents which the Company
would have been required to file with the SEC pursuant to such Section 13(a) or
15(d) if the Company were so subject, such documents to be filed with the SEC
on or prior to the respective dates (the "Required Filing Dates") by which the
Company would have been required so to file such documents if the Company were
so subject. The Company will also in any event (x) within 15 days of each
Required Filing Date (i) transmit by mail to all Holders of Notes, as their
names and addresses appear in the security register, without cost to such
Holders and (ii) file with the Trustee copies of the annual reports, quarterly
reports and other documents which the Company would have been required to file
with the SEC pursuant to Section 13(a) or 15(d) of the Exchange Act if the
Company were subject to such Sections and (y) if filing such documents by the
Company with the SEC is not permitted under the Exchange Act, promptly upon
written request and payment of the reasonable cost of duplication and delivery,
supply copies of such documents to any prospective holder of Notes at the
Company's cost.
 
  Additional Covenants. The Indenture also contains covenants with respect to
the following matters: (i) payment of principal, premium and interest; (ii)
maintenance of an office or agency in the City of New York; (iii) arrangements
regarding the handling of money held in trust; (iv) maintenance of corporate
existence; (v) payment of taxes and other claims; (vi) maintenance of
properties; and (vii) maintenance of insurance.
 
DEFAULTS AND REMEDIES
 
  The Indenture provides that each of the following constitutes an Event of
Default: (i) default for 30 days in payment of Interest on the Notes; (ii)
default in payment of principal of, or premium with respect to, the Notes;
(iii) failure by the Company or a Guarantor, if applicable, to comply with the
covenants entitled "Limitations on Restricted Payments," "Limitations on
Indebtedness," "Subsidiary Guarantees," "Limitations on Liens," "Limitations on
Asset Sales," "Limitations on Sale and Leaseback Transactions," "Limitations on
Issuances and Sales of Capital Stock of Restricted Subsidiaries," "Change of
Control," and "Limitations on Mergers; Sales of Assets;" (iv) failure by the
Company or a Guarantor, if applicable, to comply with any of its other
agreements in the Indenture, or the Notes for a period that continues for 60
days after receipt of written notice from the Trustee or from the Holders of at
least 25% of the aggregate principal amount of the Notes then outstanding,
specifying such default; (v) the Company denies or disaffirms in writing its
obligations under the Indenture or the Notes; (vi) a Guarantor denies or
disaffirms in writing its obligations under its Guarantee, or any Guarantee for
any reason ceases to be, or is asserted in writing by any Guarantor or the
Company not to be, in full force and effect and enforceable in accordance with
its terms, except to the extent contemplated by the Indenture and any such
Guarantee; (vii) a default under any Indebtedness of the Company or any of its
Subsidiaries, which default (A) is caused by a failure to pay the final
scheduled principal installment on such Indebtedness on the stated maturity
date thereof (which failure continues beyond any applicable grace period) or
(B) results in the acceleration of such Indebtedness prior to its express
maturity and, in each case, the principal amount of such Indebtedness, together
with the principal amount of any other such Indebtedness with respect to which
the principal amount remains unpaid at its final maturity or the maturity of
which has been so accelerated, aggregates $5.0 million or more; (viii) final
judgments rendered against the Company or any
 
                                       71
<PAGE>
 
of its Restricted Subsidiaries (other than any judgment as to which and only
to the extent, a reputable insurance company has acknowledged coverage of such
claim in writing) of $5.0 million or more which remain undischarged or
unstayed for a period of 60 days, and (ix) certain events of bankruptcy or
insolvency of the Company or any of the Restricted Subsidiaries.
 
  If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in principal amount of the Notes may declare the Notes due and
payable immediately. However, if an Event of Default resulting from bankruptcy
or insolvency occurs, such amount will be due and payable without any
declaration or any act on the part of the Trustee or the Holders. Such
declaration or acceleration may be rescinded and past defaults may be waived
by the Holders of a majority in principal amount of the Notes upon conditions
provided in the Indenture.
 
  Holders may not enforce the Indenture, or the Notes, except as provided
therein. The Trustee may require an indemnity satisfactory to it before
enforcing the Indenture or the Notes. Subject to certain limitations, Holders
of a majority in principal amount of the Notes will have the right to direct
the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee. The Trustee, however, may refuse to follow any direction that
conflicts with law or such Indenture, that is unduly prejudicial to the rights
of any Holder or that would subject the Trustee to personal liability. The
Trustee may withhold from the Holders of the Notes notice of any continuing
default (except a default in payment of principal, premium, if any, or
interest) if it determines in good faith that withholding notice is in their
interest. The Company is required to file periodic reports with the Trustee as
to the absence of Default. If a Default exists, the Company is required to
describe the Default and efforts undertaken to remedy the Default.
 
  Directors, officers, employees or stockholders, as such, of the Company, the
Guarantors and the other Subsidiaries of the Company will not have any
liability for any obligations of the Company or any Guarantors under the
Notes, any Guarantee or the Indenture or for any claim based on, in respect
of, or by reason of, such obligations. Each Holder of a Note by accepting a
Note waives and releases all such liability. The waiver and release are part
of the consideration for the issue of the Notes. Such waiver may not be
effective to waive liabilities under the Federal securities laws and it is the
view of the SEC that such a waiver is against public policy.
 
TRANSFER AND EXCHANGE
 
  A Holder may transfer or exchange Notes in accordance with the Indenture.
The Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by
law. The Registrar need not transfer or exchange any Note previously selected
for redemption. A registered Holder of a Note will be treated as the owner
thereof for all purposes. No Note will be valid until the Trustee or an
authenticating agent manually signs the certificate of authentication on the
Note. Each Note will become effective on the date upon which it is so signed.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
  Subject to certain exceptions, the Indenture or the Notes may be amended or
supplemented, and any past default or compliance with any provision may be
waived, with the consent of the Holders of a majority in principal amount of
the Notes then outstanding. Without the consent of any Holder, the Company and
the Guarantors may amend or supplement the Indenture or the Notes to comply
with the provisions of the Indenture in the case of a consolidation, merger or
sale of all or substantially all of the assets of the Company and its
Subsidiaries taken as a whole, to provide for uncertificated Notes in addition
to or in place of certificated Notes, to cure any ambiguity, defect or
inconsistency, to comply with any requirement of the SEC in connection with
the qualification of the Indenture under the Trust Indenture Act, to comply
with any requirement of the SEC or applicable law to effectuate the Exchange
Offer, to
 
                                      72
<PAGE>
 
add additional guarantees with respect to the Notes, to further secure the
Notes or the Guarantees, to add to the covenants of the Company or any
Subsidiary for the benefit of the Holders of the Notes, to surrender any right
or power conferred upon the Company or any Subsidiary or to make any other
change that does not adversely affect the rights of any Holder.
 
  Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any Notes held by a non-consenting Holder) (i) reduce the
principal amount of Notes whose Holders must consent to an amendment or
waiver; (ii) reduce the rate of, or change the time for payment of, interest,
including default interest, on any Notes; (iii) reduce the principal of or
change the fixed maturity of any Note(s), or alter the optional redemption
provisions, or alter the price at which the Company will offer to purchase
such Notes pursuant to an Asset Sale Offer or a Change of Control Offer; (iv)
make any Note payable in money other than that stated in such Note; (v) make
any change in the provisions of the Indenture relating to waivers of past
Defaults or the rights of Holders of the Notes to receive payments of
principal of or interest on the Notes; (vi) waive a Default or Event of
Default in the payment of principal of, premium if any, or interest on the
Notes, including any such obligation arising pursuant to an Asset Sale Offer,
a Change of Control Offer (except a rescission of acceleration of the Notes by
the Holders of at least a majority (or, in the case of the failure to make a
Change of Control Offer, two-thirds) in principal amount of the Notes then
outstanding and a waiver of the payment default that resulted from such
acceleration); (vii) waive the obligation to make an Asset Sale Offer or any
payment required to be made pursuant to an Asset Sale Offer, a Change of
Control Offer or a Guarantee; or (viii) make any change in the foregoing
amendment and waiver provisions. An amendment or waiver may not waive the
Company's obligation to make a Change of Control Offer without the consent of
the Holders of at least two-thirds in outstanding principal amount of the
Notes.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
  The Company may, at its option and at any time, elect to have all of the
obligations of the Company and each Guarantor discharged with respect to the
outstanding Notes ("Legal Defeasance") except for (i) the rights of Holders of
outstanding Notes to receive payments in respect of the principal of, premium,
if any, and interest on such Notes when such payments are due but only from
assets deposited by the Company pursuant to clause (i) of the following
paragraph, (ii) the Company's obligations with respect to the Notes concerning
issuing temporary Notes, registration or transfer of Notes, mutilated,
destroyed, lost or stolen Notes and the maintenance of an office or agency for
payment and money for security payments held in trust, (iii) the rights,
powers, trusts, duties and immunities of the Trustee, and the Company's
obligations in connection therewith and (iv) the Legal Defeasance provisions
of the Indenture. In addition, the Company may, at its option and at any time,
elect to have the obligations of the Company and any Guarantor released with
respect to certain covenants that are described in the Indenture ("Covenant
Defeasance") and thereafter any omission to comply with such obligations will
not constitute a Default or Event of Default with respect to the Notes. In the
event Covenant Defeasance occurs, certain events (not including non-payment,
bankruptcy, receivership, rehabilitation and insolvency events) described
under "Events of Default" will no longer constitute an Event of Default with
respect to the Notes.
 
  In order to effect either a Legal Defeasance or a Covenant Defeasance, (i)
the Company must irrevocably deposit with the Trustee, in trust, for the
benefit of the Holders of the Notes, cash in U.S. dollars, non-callable U.S.
Government Obligations, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent
public accountants, to pay the principal of, premium, if any, and interest on
the outstanding Notes on the stated maturity or on the applicable redemption
date, as the case may be, of such principal or installment of principal of,
premium, if any, or interest on the outstanding Notes; (ii) in the case of
Legal Defeasance, the Company will deliver to the Trustee an opinion of
counsel reasonably acceptable to the Trustee confirming that (A) the Company
has received from the Internal Revenue Service a ruling or (B) since the Issue
Date, there has been a change in the applicable Federal income tax law,
including by means of a Revenue Ruling published by the Internal Revenue
Service, in either case to the effect that, and based thereon such
 
                                      73
<PAGE>
 
opinion of counsel will confirm that, the Holders of the outstanding Notes
will not recognize income, gain or loss for Federal income tax purposes as a
result of such Legal Defeasance and will be subject to Federal income tax on
the same amounts, in the same manner and at the same times as would have been
the case if such Legal Defeasance had not occurred; (iii) in the case of
Covenant Defeasance, the Company will deliver to the Trustee an opinion of
counsel reasonably acceptable to the Trustee confirming that the Holders of
the outstanding Notes will not recognize income, gain or loss for Federal
income tax purposes as a result of such Covenant Defeasance and will be
subject to Federal income tax, on the same amounts, in the same manner and at
the same times as would have been the case if such Covenant Defeasance had not
occurred; (iv) no Default or Event of Default has occurred and is continuing
on the date of such deposit or insofar as Events of Default from bankruptcy or
insolvency events are concerned, at any time in the period ending on the 91st
day after the date of deposit; (v) such Legal Defeasance or Covenant
Defeasance will not result in a breach or violation of, or constitute a
default under any material agreement or instrument (other than the Indenture)
to which the Company or any Guarantor is a party or by which the Company or
any Guarantor is bound; (vi) the Company will deliver to the Trustee an
opinion of counsel to the effect that (A) the trust funds will not be subject
to any rights of holders of Senior Indebtedness of the Company or of any
Guarantor and (B) after the 91st day following the deposit, the trust funds
will not be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally; (vii)
the Company will deliver to the Trustee an officers' certificate stating that
the deposit was not made by the Company with the intent of preferring the
Holders of Notes or any Guarantee over the other creditors of the Company or
any Guarantor or with the intent of defeating, hindering, delaying or
defrauding creditors of the Company or any Guarantor or others; and (viii) the
Company will deliver to the Trustee an officers' certificate and an opinion of
counsel, each stating that all conditions precedent provided for relating to
the Legal Defeasance or the Covenant Defeasance have been complied with.
 
THE TRUSTEE
 
  The Indenture provides that, except during the continuance of an Event of
Default, the Trustee will perform only such duties as are specifically set
forth in the Indenture. During the existence of an Event of Default, the
Trustee will exercise such rights and powers vested in it under the Indenture
and use the same degree of care and skill in their exercise as a prudent
Person would exercise under the circumstances in the conduct of such Person's
own affairs.
 
  The Indenture and provisions of the Trust Indenture Act incorporated by
reference therein contain limitations on the rights of the Trustee, should it
become a creditor of the Company or any Guarantor, to obtain payment of claim
in certain cases or to realize on certain property received by it in respect
of any such claim as security or otherwise. The Trustee will be permitted to
engage in other transactions; however, if it acquires any conflicting
interest, it must eliminate such conflict or resign.
 
  The Company or any Guarantor may have customary banking relationships with
the Trustee in the ordinary course of business.
 
BOOK-ENTRY; DELIVERY AND FORM
 
  The certificates representing the New Notes will be issued in fully
registered form. Except as described in the next paragraph, the Company
expects that the New Notes initially will each be represented by a single
global certificate in fully registered form (the "Global Note") and will be
deposited with the Trustee as custodian for The Depository Trust Company
("DTC") and registered in the name of a nominee of DTC.
 
  New Notes issued in exchange for Old Notes (i) originally purchased by
institutional investors that were "accredited investors" (as defined in Rule
501(a)(1),(2),(3) or (7) under the Securities Act) ("Institutional Accredited
Investors") who were not "Qualified Institutional Buyers" (as defined in Rule
 
                                      74
<PAGE>
 
144A under the Securities Act) ("QIBs"), or (ii) held by QIBs who elected to
take physical delivery of their certificates instead of holding their interest
through the Global Note (and which were thus ineligible to trade through DTC)
(collectively referred to herein as the "Non-Global Purchasers") will be
issued in registered form (the "Certificated Notes"). The Company expects that
upon the transfer to a QIB of Certificated Notes initially issued to a Non-
Global Purchaser, such Certificated Notes will, unless the transferee requests
otherwise or the Global Note has previously been exchanged in whole for
Certificated Notes, be exchanged for an interest in the Global Note.
 
  Global Note. The Company expects that upon the issuance of the Global Note,
DTC or its custodian will credit, on its book-entry registration and transfer
system, the respective principal amount of Notes of the individual beneficial
interests represented by such Global Note to the accounts of Persons who have
accounts with such depositary. Such accounts initially will be designated by
or on behalf of the Initial Purchaser. Ownership of beneficial interests in
the Global Note will be limited to Persons who have accounts with DTC
("participants") or Persons who hold interests through participants. Ownership
of beneficial interests in the Global Note will be shown on, and the transfer
of that ownership will be effected only through, records maintained by DTC or
its nominee (with respect to interests of participants) and the records of
participants (with respect to interests of Persons other than participants).
QIBs may hold their interests in the Global Note directly through DTC if they
are participants in such system, or indirectly through organizations which are
participants in such system.
 
  So long as DTC, or its nominee, is the registered owner or holder of the
Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the Notes represented by such Global Note for all
purposes under the Indenture and the Notes. No beneficial owner of an interest
in the Global Note will be able to transfer that interest except in accordance
with DTC's applicable procedures, in addition to those provided for under the
Indenture.
 
  Payments of the principal of, premium (if any) and interest on, the Global
Note will be made to DTC or its nominee, as the case may be, as the registered
owner thereof. Neither the Company, the Trustee nor any Paying Agent will have
any responsibility or liability for any aspect of the record relating to or
payments made on account of beneficial ownership interests in the Global Note
or for maintaining, supervising or reviewing any record relating to such
beneficial ownership interest.
 
  The Company expects that DTC or its nominee, upon receipt of any payment of
principal, premium, if any, or interest in respect of the Global Note, will
credit participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of such Global Note as
shown on the records of DTC or its nominee. The Company also expects that
payments by participants to owners of beneficial interests in such Global Note
held through such participants will be governed by standing instructions and
customary practice, as is now the case with securities held for the accounts
of customers registered in the names of nominees for such customers. Such
payments will be the responsibility of such participants.
 
  The Company expects that transfers between participants in DTC will be
effected in the ordinary way in accordance with DTC rules and will be settled
in clearinghouse funds. If a holder requires physical delivery of a
Certificated Note for any reason, including to sell Notes to Persons in states
which require physical delivery of such Notes or to pledge such Notes, such
holder must transfer its interest in the Global Note in accordance with the
normal procedures of DTC and the procedures set forth in the Indenture.
 
  DTC has advised the Company that it will take any action permitted to be
taken by a holder of Notes (including the presentation of Notes for exchange
as described below) only at the direction of one or more participants to whose
account the DTC interests in the Global Note is credited and only in respect
of such portion of the aggregate principal amount of Notes as to which such
participant or participants has or have given such direction. However, if
there is an Event of Default under the Notes or the Indenture, DTC will
exchange the Global Note for Certificated Notes, which it will distribute to
its participants.
 
                                      75
<PAGE>
 
  To the Company's knowledge, DTC is a limited purpose trust company organized
under the laws of the State of New York, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the Uniform Commercial
Code and a "Clearing Agency" registered pursuant to the provisions of Section
17A of the Exchange Act. DTC was created to hold securities for its
participants and facilitate the clearance and settlement of securities
transactions between participants through electronic book-entry changes in
accounts of its participants, thereby eliminating the need for physical
movement of certificates. Participants include securities brokers and dealers
(including the Initial Purchasers), banks, trust companies and clearing
corporations and certain other organizations. Indirect access to the DTC
system is available to others such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly ("indirect participants").
 
  Although DTC customarily agrees to the foregoing procedures in order to
facilitate transfers of interests in global notes among participants of DTC,
it is under no obligation to perform such procedures, and such procedures may
be discontinued at any time. Neither the Company nor the Trustee will have any
responsibility for the performance by DTC or its participants or indirect
participants of their respective obligations under the rules and procedures
governing their operations.
 
  Certificated Securities. If DTC is at any time unwilling or unable to
continue as a depositary for the Global Note and a successor depositary is not
appointed by the Company within 90 days, Certificated Notes will be issued in
exchange for the Global Note.

Subsidiary of, such specified Person.
 
  "Affiliate" means, with respect to any party, any Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with such party including any estate or trust under will of such

with"), as used with respect to any Person, means the possession, directly or
indirectly, of the power to direct or cause the direction of the management or
policies of such Person, whether through the ownership of voting securities,
by agreement or otherwise; provided, however, that beneficial ownership of 5%
or more of the voting securities of a Person will be deemed to be control.
 
  "Asset Sale" means, with respect to the Company or any Restricted
Subsidiary, the sale, lease, conveyance or other disposition (including,
without limitation, by way of merger or consolidation, and whether by

Subsidiary's assets (including, without limitation, (x) any sale or other
disposition of Equity Interests of any Restricted Subsidiary and (y) any sale

for which such lease has been extended). As used in the preceding sentence,
the "total net obligations of the lessee for rental payments" under any lease
for any such period means the sum of rental and other payments required to be
paid with respect to such period by the lessee thereunder excluding any
amounts required to be paid by such lessee on account of maintenance and
repairs, insurance, taxes, assessments, water rates or similar charges. In the
case of any lease which is terminable by the lessee upon payment of a penalty,

will be considered as required to be paid under such lease subsequent to the
first date upon which it may be so terminated.

receivable or inventory as of a specific date, the Company may utilize the
most recent available quarterly or annual financial report for purposes of
calculating the Borrowing Base.
 
  "Capital Stock" means, with respect to any Person, any common stock,
preferred stock and any other capital stock of such Person and shares,
interest, participations or other ownership interest (however designated), of

partnership.

  "Consolidated Net Income" means, for any period, and as to any Person, the
aggregate Net Income of such Person and its Subsidiaries (other than, in the
case of the Company, the Unrestricted Subsidiaries of the Company) for such
period determined on a consolidated basis in accordance with GAAP; provided
that (i) the Net Income of any Person which is not a Subsidiary of such Person
but which is consolidated with such Person or is accounted for by such Person
by the equity method of accounting will be included only to the extent of the

retention agreement with respect to property acquired by such Person or
otherwise representing the deferred and unpaid balance of the purchase price
of any such property, including all indebtedness created or arising in the
manner specified in this clause even though the rights and remedies of the
seller or lender under such agreement in the event of default are limited to
repossession or sale of such property; (viii) guarantees, direct or indirect,
of any indebtedness of other Persons referred to in clauses (i) through
(vii) above, or of dividends or leases, taxes or other obligations of other
Persons, excluding any guarantee arising out of the endorsement of negotiable
instruments for collection in the ordinary course of business; (ix) contingent
obligations in respect of, or to purchase or otherwise acquire or be

the foregoing indebtedness (other than letters of credit and Hedging
Obligations) would appear as a liability on the balance sheet of such Person
in accordance with GAAP. For purposes of the foregoing definition, the
"maximum fixed repurchase price" of any Redeemable Stock which does not have a
fixed repurchase price will be calculated in accordance with the terms of such
Redeemable Stock as if such Redeemable Stock were purchased on any date on
which Indebtedness is required to be determined pursuant to the Indenture. As
used herein, Indebtedness with respect to any Hedging Obligation means, with
respect to any specified Person on any date, the net amount (if any) that
would be payable by such specified Person upon the liquidation, close-out or
early termination on such date of such Hedging Obligation. For purposes of the
foregoing, any settlement amount payable upon the liquidation, close-out or
early termination of a Hedging Obligation will be calculated by the Company in
good faith and in a commercially reasonable manner on the basis that such
liquidation, close-out or early termination results from an event of default
or other similar event with respect to such specified Person. Any reference in
this definition to indebtedness will be deemed to include any renewals,
extensions and refundings of any such indebtedness or any indebtedness issued
in exchange for such indebtedness.
 
  "Independent Director" means a director of the Company other than a director

year or (ii) who is a director, an employee, insider, associate or Affiliate

  "Interest Coverage Ratio" as of any date of determination means the ratio of
(i) the aggregate amount of EBITDA for the period of the most recent four
consecutive fiscal quarters for which internal financial statements are
available prior to the date of such determination to (ii) Consolidated
Interest Expense for such four fiscal quarters of the Company and its
Restricted Subsidiaries; provided, however, that (A) if the Company or any
Restricted Subsidiary has incurred any Indebtedness since the beginning of
such period that remains outstanding or if the transaction giving rise to the
need to calculate the Interest Coverage
 
                                      80
<PAGE>
 
Ratio is an incurrence of Indebtedness, or both, EBITDA and Consolidated
Interest Expense for such period will be calculated after giving effect on a
pro forma basis to such Indebtedness as if such Indebtedness had been issued
on the first day of such period and the discharge of any other Indebtedness
repaid, repurchased, defeased or otherwise discharged with the proceeds of
such new Indebtedness as if such discharge had occurred on the first day of
such period, (B) if since the beginning of such period the Company or any
Restricted Subsidiary has made any Asset Sale, EBITDA for such period will be
reduced by an amount equal to EBITDA (if positive), directly attributable to
the assets which are the subject of such Asset Sale for such period, or
increased by an amount equal to EBITDA (if negative), directly attributable
thereto for such period and Consolidated Interest Expense for such period will
be reduced by an amount equal to the Consolidated Interest Expense directly
attributable to any Indebtedness of the Company or any Restricted Subsidiary
repaid, repurchased, defeased or otherwise discharged with respect to the
Company and its continuing Restricted Subsidiaries in connection with any such
sale or other disposition for such period (or, if the Capital Stock of any
Subsidiary is sold, the Consolidated Interest Expense for such period directly
attributable to the Indebtedness of such Subsidiary to the extent the Company
and its continuing Restricted Subsidiaries are no longer liable for such
Indebtedness after such sale), (C) if since the beginning of such period the
Company or any Restricted Subsidiary (by merger or otherwise) has made an
Investment in any Restricted Subsidiary (or any Person which becomes a
Restricted Subsidiary) or an acquisition of assets, including any acquisition
of assets occurring in connection with a transaction causing a calculation to
be made under the Indenture, which constitutes all or substantially all of an
operating unit of a business, EBITDA and Consolidated Interest Expense for
such period will be calculated after giving pro forma effect thereto
(including the incurrence of any Indebtedness) as if such Investment or
acquisition occurred on the first day of such period and (D) in making such
computation, Consolidated Interest Expense attributable to any Indebtedness
incurred under any revolving credit facility will be computed based on the
average daily balance of such Indebtedness during such period. For purposes of
this definition, whenever pro forma effect is to be given to an acquisition of
assets, the amount of income or earnings relating thereto, and the amount of
Consolidated Interest Expense associated with any Indebtedness incurred in
connection therewith, the pro forma calculations will be determined in good
faith by a responsible financial or accounting officer of the Company. If any
Indebtedness bears a floating rate of interest and is being given pro forma
effect, the interest on such Indebtedness will be calculated as if the rate in
effect on the date of determination had been the applicable rate for the
entire period.
 
  "Investment" means any direct or indirect advance, loan, other extension of
credit or capital contribution (by means of any transfer of cash or other

a substantial part of the business, Equity Interests or other evidence of
beneficial ownership of, or any other investment in or guarantee of any
Indebtedness (other than guarantees of Indebtedness of the Company or any
Restricted Subsidiary permitted by the covenant described under "Limitations

customary course of business and on commercially reasonable terms.

of such asset or assets required by GAAP, and (v) all distributions and other

Fair Market Value thereof as determined in good faith by the Board of
Directors of the Company. The amount of any taxes required to be accrued as a
liability under GAAP as a consequence of an Asset Sale will be the amount
thereof as determined in good faith by the Board of Directors of the Company.

                              REGISTRATION RIGHTS
 
  Pursuant to the Registration Rights Agreement, the Company and the
Guarantors agreed, for the benefit of holders of the Old Notes, that they
would, at their expense (i) on or prior to the February 3, 1997, file the
Exchange Offer Registration Statement with the Commission with respect to the
New Notes, which will have terms identical to the Old Notes and will be
guaranteed by the Guarantors on the same terms as the Old Guarantees (except
that the New Notes will not contain terms with respect to the transfer
restrictions or any provision relating to this paragraph) and (ii) use their
best efforts to cause the Exchange Offer Registration Statement to be declared
effective under the Securities Act by April 4, 1997. The Registration
Statement of which this Prospectus is a part constitutes the Exchange Offer
Registration Statement. Upon effectiveness of the Exchange Offer Registration
Statement, the Company and the Guarantors agreed that they would offer to all
holders of the Old Notes an opportunity to exchange their securities for a
like principal amount of the New Notes. The Company and the Guarantors agreed
to keep the Exchange Offer open for acceptance for not less than 20 business
days after the date of this Prospectus, and will comply with Regulation 14E
and Rule 13e-4 under the Exchange Act (other than the filing requirements of
Rule 13e-4). For each Old Note surrendered to the Company for exchange
pursuant to the Exchange Offer, the holder of such Note will receive a New
Note having a principal amount at maturity equal to that of the surrendered
Old Note. Interest on each New Note will accrue from the last interest payment
date on which interest was paid on the Old Note surrendered in exchange
therefor or if no interest has been paid on such Old Note, from December 5,
1996.
 
  Under existing interpretations of the staff of the Commission's Division of
Corporation Finance (the "Staff"), the New Notes will generally be freely
transferable after the Exchange Offer without further registration under the
Securities Act; provided that broker-dealers ("Participating Broker-Dealers")
receiving New Notes in the Exchange Offer will be subject to a prospectus
delivery requirement with respect to resales of such New Notes. To date, the
Staff has taken the position that Participating Broker-Dealers may fulfill
their prospectus delivery requirements with respect to transactions involving
an exchange of securities such as the exchange pursuant to the Exchange Offer
(other than a resale of an unsold allotment from the sale of the Old Notes to
the Initial Purchasers) with this Prospectus. Pursuant to the Registration
Rights Agreement, the Company has agreed to permit Participating Broker-
Dealers and other persons, if any, subject to similar prospectus delivery
requirements to use this Prospectus in connection with the resale of such New
Notes.
 
  Each holder of the Old Notes who wishes to exchange its Old Notes for New
Notes in the Exchange Offer will be required to make certain representations
to the Company, including that (i) any New Notes to be received by it will be
acquired in the ordinary course of its business, (ii) it has no arrangement or
understanding with any person to participate in a public distribution (within
the meaning of the Securities Act) of the New Notes and (iii) it is not an
"affiliate," as defined in Rule 405 of the Securities Act, of the Company or
the Guarantors, or if it is such an affiliate, that it will comply with the
registration and prospectus delivery requirements of the Securities Act to the
extent applicable to it.
 
  In addition, each holder who is not a broker-dealer will be required to
represent that it is not engaged in, and does not intend to engage in, a
public distribution of the New Notes. Each holder who is a broker-dealer and
who receives New Notes for its own account in exchange for Old Notes that were
acquired by it as a result of market-making activities or other trading
activities, will be required to acknowledge that it will deliver a prospectus
in connection with any resale by it of such New Notes.
 
  In the event for any reason the Exchange Offer is not consummated by May 4,
1997, or if the Initial Purchasers so request with respect to the Old Notes
not eligible to be exchanged for New Notes in the Exchange Offer or if any
holder of Old Notes is not eligible to participate in the Exchange Offer or
does not receive freely tradeable New Notes in the Exchange Offer, the Company
and the Guarantors will, at their expense, (a) promptly file a shelf
registration statement (a "Shelf Registration Statement" and together with the
Exchange Offer Registration Statement, the "Registration Statements")
permitting
 
                                      85
<PAGE>
 
resales from time to time of the Notes, (b) use their best efforts to cause
such registration statement to become effective and (c) use their best efforts
to keep such registration statement current and effective until three years
from the date it becomes effective or such shorter period that will terminate
when all the Notes covered by such registration statement have been sold
pursuant thereto. The Company and the Guarantors, at their expense, will
provide to each holder of the Notes copies of the prospectus, which is a part
of the Shelf Registration Statement, notify each such holder when the Shelf
Registration Statement has become effective and take certain other actions as
are required to permit unrestricted resales of the Notes from time to time. A
holder of Notes who sells such Notes pursuant to the Shelf Registration
Statement generally will be required to be named as a selling securityholder
in the related prospectus and to deliver a prospectus to purchasers, will be
subject to certain of the civil liability provisions under the Securities Act
in connection with such sales and will be bound by the provisions of the
Registration Rights Agreement which are applicable to such holder (including
certain indemnification obligations).
 
  In the event that (i) the Exchange Offer is not consummated on or prior to
May 4, 1997, (ii) the Shelf Registration Statement is not filed or declared
effective within the required time periods or (iii) any of the Registration
Statements required by the Registration Rights Agreement is declared effective
but thereafter ceases to be effective (except as specifically permitted
therein) for a period of 15 consecutive days without being succeeded
immediately by any additional Registration Statement filed and declared
effective (each such event, a "Registration Default"), the interest rate borne
by the Notes shall be increased by 25 basis points per annum for the 90-day
period following such Registration Default. Such interest rate will increase
by an additional 25 basis points per annum at the beginning of each subsequent
90-day period following such Registration Default, up to a maximum aggregate
increase of 100 basis points per annum. Upon (x) the consummation of the
Exchange Offer or (y) the filing or the effectiveness of the Shelf
Registration Statement, as the case may be, the interest rate borne by the
Notes will be reduced from and including the date on which any of the events
specified in clauses (x) or (y) above occur by the amount of the related
increase in the interest rate.
 
  The summary herein of certain provisions of the Registration Rights
Agreement does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, all the provisions of the Registration Rights
Agreement, a copy of which is available upon request to the Company.
 
                 CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES
 
  The following general discussion summarizes certain of the material U.S.
federal income tax aspects of the acquisition, ownership and disposition of
the New Notes. This discussion is based upon the Internal Revenue Code of
1986, as amended (the "Code"), Treasury Regulations, Internal Revenue Service
("IRS") rulings and judicial decisions now in effect, all of which are subject
to change (possibly with retroactive effect) or different interpretations.
This discussion is generally limited to the tax consequences to initial
holders and does not purport to deal with all aspects of federal income
taxation that may be relevant to a particular investor's decision to purchase
the New Notes. This discussion is not intended to be wholly applicable to all
categories of investors, some of which, such as dealers in securities, banks,
insurance companies and tax-exempt organizations, may be subject to special
rules. In addition, this discussion is limited to persons that will hold the
New Notes represented thereby as a "capital asset" within the meaning of
section 1221 of the Code.
 
  ALL PROSPECTIVE PURCHASERS OF THE NEW NOTES ARE ADVISED TO CONSULT THEIR OWN
TAX ADVISORS REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES
OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NEW NOTES.
 
  Exchange Offer. The exchange of the New Notes for the Old Notes pursuant to
the Exchange Offer will not be treated as an "exchange" for U.S. federal
income tax purposes because the New Notes will not be considered to differ
materially in kind or extent from the Old Notes. Rather, the New Notes
 
                                      86
<PAGE>
 
received by a holder will be treated as a continuation of the Old Notes in the
hands of such holder. As a result, there will be no U.S. federal income tax
consequences to holders exchanging the Old Notes for the New Notes pursuant to
the Exchange Offer. The holder must continue to include stated interest in
income as if the exchange had not occurred. Similarly, there would be no U.S.
federal income tax consequences to a holder of Old Notes that does not
participate in the Exchange Offer.
 
  Market Discount. Investors acquiring New Notes pursuant to this Prospectus
should note that the resale of the New Notes may be adversely affected by the
market discount provisions of sections 1276 through 1278 of the Code. Under
the market discount rules, if a holder of a New Note (other than a holder who
purchased the New Note upon original issuance) purchases it at a market
discount (i.e., at a price below its stated redemption price at maturity) in
excess of a statutorily-defined de minimis amount and thereafter recognizes
gain upon a disposition or retirement of the New Note, then the lesser of the
gain recognized or the portion of the market discount that accrued on a
ratable basis (or, if elected, on a constant interest rate basis) generally
will be treated as ordinary income at the time of the disposition. Moreover,
any market discount in a New Note may be taxable to an investor to the extent
of appreciation at the time of certain otherwise non-taxable transactions
(e.g., gifts). Absent an election to include market discount in income as it
accrues, a holder of a market discount debt instrument may be required to
defer a portion of any interest expense that otherwise may be deductible on
any indebtedness incurred or maintained to purchase or carry such debt
instrument until the holder disposes of the debt instrument in a taxable
transaction.
 
  Sale, Exchange or Retirement of the New Notes. Each holder of New Notes
generally will recognize gain or loss upon the sale, exchange, repurchase,
redemption, retirement or other disposition of those New Notes measured by the
difference (if any) between (i) the amount of cash and the fair market value
of any property received (except to the extent that such cash or other
property is attributable to the payment of accrued interest not previously
included in income, which amount will be taxable as ordinary income) and (ii)
the holder's adjusted tax basis in those New Notes (including any market
discount previously included in income by the holder). Any such gain or loss
recognized on the sale, exchange, repurchase, redemption, retirement or other
disposition of a New Note should be capital gain or loss (except as discussed
under "Market Discount" above), and would be long-term capital gain or loss if
the New Note had been held for more than one year at the time of the sale or
exchange. An investor's initial basis in a New Note will be the same as such
investor's basis in the Old Note at the time of the Exchange Offer.
 
  Backup Withholding. A holder of New Notes may be subject to "backup
withholding" at a rate of 31% with respect to certain "reportable payments,"
including interest payments and, under certain circumstances, principal
payments on the New Notes. These backup withholding rules apply if the holder,
among other things, (i) fails to furnish a social security number or other
taxpayer identification number ("TIN") certified under penalties of perjury
within a reasonable time after the request therefor, (ii) furnishes an
incorrect TIN, (iii) fails to report properly interest, or (iv) under certain
circumstances, fails to provide a certified statement, signed under penalties
of perjury, that the TIN furnished is the correct number and that such holder
is not subject to backup withholding. A holder who does not provide the
Company with its correct TIN also may be subject to penalties imposed by the
IRS. Any amount withheld from a payment to a holder under the backup
withholding rules is creditable against the holder's federal income tax
liability, provided that the required information is furnished to the IRS.
Backup withholding will not apply, however, with respect to payments made to
certain holders, including corporations, tax-exempt organizations and certain
foreign persons ("exempt recipients"), provided their exemptions from backup
withholding are properly established.
 
  The amount of any "reportable payments" including interest made to the
holders of New Notes (other than to holders which are exempt recipients) and
the amount of tax withheld, if any, with respect to such payments will be
reported to such holders and to the IRS for each calendar year.

  Foreign Holders. The following discussion is a summary of certain U.S.
federal income tax consequences to a Foreign Person that holds a New Note. The
term "Foreign Person" means a nonresident alien individual or foreign
corporation, but only if the income or gain on the New Note is not
"effectively connected with the conduct of a trade or business within the
U.S." If the income or gain on the New Note is "effectively connected with the
conduct of a trade or business within the U.S.," then the nonresident alien
individual or foreign corporation will be subject to tax on such income or
gain in essentially the same manner as a U.S. citizen or resident or a
domestic corporation, as discussed above, and in the case of a foreign
corporation, may also be subject to the branch profits tax.
 
  Under the portfolio interest exception to the general rules for the
withholding of tax on interest paid to a Foreign Person, a Foreign Person will
not be subject to U.S. federal income tax (or to withholding) on interest
payments on a New Note, provided that (i) the Foreign Person does not actually
or constructively own 10% or more of the total combined voting power of all
classes of stock of the Company entitled to vote and is not a controlled
foreign corporation with respect to the U.S. that is related to the Company
through stock ownership, and (ii) the Company, its paying agent or the person
who would otherwise be required to withhold tax receives either (A) a
statement (an "Owner's Statement") signed under penalties of perjury by the
beneficial owner of the New Note in which the owner certifies that the owner
is not a U.S. person and which provides the owner's name and address, or (B) a
statement signed under penalties of perjury by the Financial Institution
holding the New Note on behalf of the beneficial owner, together with a copy
of the Owner's Statement. The term "Financial Institution" means a securities
clearing organization, bank or other financial institution that holds
customers' securities in the ordinary course of its trade or business and that
holds a New Note on behalf of the owner of the New Note. A Foreign Person who
does not qualify for the "portfolio interest" exception, would, under current
law, generally be subject to U.S. federal withholding tax at a flat rate of
30% (or lower applicable treaty rate) on interest payments.
 
  In general, gain recognized by a Foreign Person upon the redemption, sale or
exchange of a New Note (including any gain representing accrued market
discount) will not be subject to U.S. federal income tax. However, a Foreign
Person may be subject to U.S. federal income tax at a flat rate of 30% (unless
exempt by an applicable treaty) on any such gain if the Foreign Person is an
individual present in the U.S. for 183 days or more during the taxable year in
which the New Note is redeemed, sold or exchanged, and certain other
requirements are met.

                             PLAN OF DISTRIBUTION
 
  Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of New Notes received in exchange for Old Notes where
such Old Notes were acquired as a result of market-making activities or other
trading activities. Based on interpretations by the staff of the SEC, as set
forth in no-action letters issued to third parties, the Company believes that
New Notes issued pursuant to the Exchange Offer in exchange for Old Notes may
be offered for resale, resold or otherwise transferred by holders thereof
(other than any such holder which is an "affiliate" of the Company within the
meaning of Rule 405 under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act,
provided that such New Notes are acquired in the ordinary course of such
holders' business and such holders, other than broker-dealers, have no
arrangement or understanding with any person to participate in the
distribution of such New Notes. However, the SEC has not considered the
Exchange Offer in the content of a no-action letter and there can be no
assurance that the staff of the SEC would make a similar determination with
respect to the Exchange Offer as in such other circumstances. Each holder of
the Old Notes who wishes to exchange its Old Notes for New Notes in the
Exchange Offer will be required to make certain representations to the
Company, including that (i) any New Notes to be received by it will be
acquired in the ordinary course of its business, (ii) it has no arrangement or
understanding with any person to participate in a public distribution (within
the meaning of the Securities Act) of the New Notes and (iii) it is not an
"affiliate," as defined in Rule 405 of the Securities Act, of the Company or
the Guarantors, or if it is such an affiliate, that it will comply with the
registration and prospectus delivery requirements of the Securities Act to the
extent applicable to it. If any Holder is an affiliate of the Company or in
engaged in or intends to engage in or has any arrangement or understanding
with respect to the distribution of the New Notes to be acquired pursuant to
the Exchange Offer, such Holder (i) may not rely on the applicable
interpretations of the staff of the SEC and (ii) must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. Each broker-dealer that receives New
Notes for its own account in exchange for Old Notes pursuant to the Exchange
Offer must acknowledge that such Old Notes were acquired by such broker-dealer
as a result of market-making activities or other trading activities and that
it will deliver a prospectus in connection with any resale of such New Notes.
The Company has agreed that, for a period of 150 days after the date of this
Prospectus, it will make this prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale.
 
  The Company will not receive any proceeds from any sale of New Notes by
broker-dealers. New Notes received by broker-dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the New Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at
prices related to such prevailing market prices or negotiated prices. Any such
resale may be made directly to purchasers or to or through brokers or dealers
who may receive compensation in the form of commissions or concessions from
any such broker-dealer or the purchasers of any such New Notes. Any broker-
dealer that resells New Notes that were received by it for its own account
pursuant to the Exchange Offer and any broker or dealer that participates in a
distribution of such New Notes may be deemed to be an "underwriter" within the
meaning of the Securities Act and any profit on any such resale of New Notes
and any commission or concessions received by any such persons may be deemed
to be underwriting compensation under the Securities Act. The Letter of
Transmittal states that, by acknowledging that it will deliver and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act.
 
  The Company has agreed, pursuant to the Registration Rights Agreement, to
pay all expenses incident to the Exchange Offer (including the expenses of one
counsel for all the holders of the Notes as a single
 
                                      89
<PAGE>
 
class) other than commissions or concessions of any brokers or dealers and
will indemnify the holders of the Notes (including any broker-dealers) against
certain liabilities, including liabilities under the Securities Act.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Radnor Holdings Corporation:
 
  We have audited the accompanying consolidated balance sheets of RADNOR
HOLDINGS CORPORATION (a Delaware corporation) (formerly Benchmark Corporation
of Delaware) as of December 31, 1994 and 1995, and the related consolidated
statements of operations, stockholders' (deficit) equity and cash flows for
the years ended December 31, 1993, 1994 and 1995. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Radnor
Holdings Corporation as of December 31, 1994 and 1995, and the results of its
operations and its cash flows for the years ended December 31, 1993, 1994 and
1995, in conformity with generally accepted accounting principles.

               (INCLUDING NOTES APPLICABLE TO UNAUDITED PERIODS)
 
(1) ORGANIZATION, ACQUISITIONS AND DISCONTINUED OPERATIONS:
 
 The Company
 
  Radnor Holdings Corporation (the Company) (formerly Benchmark Corporation of
Delaware) was incorporated in Delaware on November 6, 1991 to acquire the
outstanding stock of Benchmark Holdings, Inc. (Benchmark) and WinCup Holdings,
Inc. (WinCup). The Company manufactures and distributes foam cups and
containers, thermoformed lids and various other products used by the
foodservice industry. The Company's products are primarily sold to national,
institutional and retail customers throughout the U.S., in Mexico and in other
countries. The Company and its subsidiaries market their products under a
variety of brand and trade names, including "WinCup" and "Handi-Kup."
 
  The Company has a number of large national accounts and supplies products to
a number of large foodservice distributors. The five largest accounts
represented approximately 35% and 38% of the Company's net sales for fiscal
year 1995 and the nine months ended September 30, 1996, respectively. Although
the Company has not lost sales from its key customers in fiscal year 1995 or
1996 to date, if any of such customers substantially reduces its level of
purchases from the Company, the Company's profitability could be adversely
affected. Moreover, continued consolidation among distributors in the
foodservice industry could result in an increasingly concentrated customer
base or the loss of certain customers.
 
  As further discussed below, (i) the Company sold substantially all of the
assets of Benchmark's cutlery and straws business as well as the assets of
WinCup's thermoformed cup business pursuant to an Asset Purchase Agreement
dated October 31, 1995, and (ii) the Company acquired the assets of the J. R.
Cup foam cup division (J. R. Cup) of James River Paper Company, Inc. (James
River) through the formation of a joint venture (the Joint Venture) on January
20, 1996.
 
 Joint Venture
 
  On January 20, 1996, WinCup entered into the Joint Venture with James River,
whereby both parties contributed their fixed assets, leasehold improvements,
technology, patents, trademarks, real property and other noncurrent assets
associated with their foam cup and container and thermoformed lid
manufacturing operations and all inventory, spare parts and other current
assets, excluding cash and accounts receivable. The Joint Venture is
structured as a Delaware limited partnership with WinCup as the sole general
partner and James River as the sole limited partner. Ownership interests are
allocated 55% to WinCup and 45% to James River.
 
  The formation and capitalization of the Joint Venture has been accounted for
as a business combination in accordance with Accounting Principles Board
Opinion No. 16 (APB No. 16), Business Combinations. Because WinCup is the sole
general partner of the Joint Venture with a 55% controlling interest, the
contribution of its assets and liabilities has been accounted for at WinCup's
historical cost basis in such assets and liabilities. The contribution of
assets and liabilities by James River has been accounted for as a purchase by
WinCup in accordance with APB No. 16 and, accordingly, the assets and
liabilities of James River have been recorded at their estimated fair values
at the date of the purchase.
 
  The purchase price consisted of approximately (i) $19.1 million of cash,
(ii) $16.8 million of promissory notes (Note 3), (iii) the assumption of $1.0
million of liabilities and (iv) estimated additional consideration of $17.7
million for James River's 45% interest in the Joint Venture which is included
in the accompanying balance sheet as payable to James River.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

  The fair value of the assets acquired has been allocated as follows:

      <S>                                                         <C>
      Inventories................................................    $ 8,200
      Property, plant and equipment..............................     46,400
                                                                     -------
                                                                     $54,600
                                                                     =======
</TABLE>
 
  Pursuant to the Joint Venture Agreement (the Agreement), WinCup has the
option to acquire all or part of James River's interest at the times and for
the applicable prices as set forth in the Agreement. The price for 100% of
James River's interest ranges from $15.0 million at January 20, 1996, to $37.3
million at January 20, 2001. Furthermore, James River may at any time
beginning on the fifth anniversary of the Agreement require WinCup to acquire
its 45% interest for $37.3 million. In either case, the purchase price is
increased by any amounts remaining outstanding to James River under certain
promissory notes discussed in Note 3, except that if WinCup exercises its
option to purchase James River's interest (i) within fifteen months of the
Agreement, $6.0 million of the promissory notes described in Note 3 may be
redeemed at 75% of their face value and (ii) on or before the second
anniversary of the Agreement, the interest on such notes will be forgiven.
 
  As discussed above, James River can require WinCup to acquire its 45%
interest in the Joint Venture at any time after the fifth anniversary of the
Agreement; therefore, the transaction has been accounted for as if WinCup
purchased 100% of the Joint Venture. Furthermore, management anticipates
exercising its option to purchase James River's interest on or before June 30,
1997 at approximately $17.7 million, which is the present value of the price
set forth in the Agreement corresponding to the estimated purchase date.
Management has included the anticipated cost of exercising its option as part
of the purchase price allocated to the net assets acquired. Any change to the
estimated option exercise price due to a change in the timing of the purchase
of James River's interest will be reflected as an increase or decrease to the
cost of net assets acquired.
 
 WinCup
 
  On February 28, 1992, WinCup entered into a Stock Purchase Agreement (the
WinCup Agreement) with Kimberly-Clark Tissue Company, formerly known as Scott
Paper Company (KCTC), for the purchase of Scott Container Products Group, Inc.
(SCPG) and WinCup, Inc. (WinCup, Inc.). The acquisition was accounted for as a
purchase in accordance with APB No. 16 and, accordingly, the purchased assets
and assumed liabilities of SCPG and WinCup, Inc. were recorded at their
estimated fair values at the date of acquisition.
 
  Pursuant to the WinCup Agreement, KCTC was granted warrants (that expire on
April 30, 2002) for the purchase of shares of nonvoting common stock of the
Company representing up to 20 percent of the then outstanding capital stock of
the Company at a price of $25,000 per each 1 percent of the total outstanding
capital stock acquired. Furthermore, depending on the annual performance of
WinCup, additional cash of up to $5.0 million (no more than $1.0 million in
any fiscal year beginning with December 31, 1993 and ending on December 31,
1997) may be paid to KCTC. No amounts have been paid to KCTC pursuant to this
provision of the WinCup Agreement. The Company also indemnified KCTC for up to
$3.0 million related to draws made by WinCup's bank lenders on a letter of
credit issued by KCTC in WinCup's favor. During 1995, KCTC exercised its
indemnification rights under the WinCup Agreement in conjunction with the
formation of the Joint Venture. This $3.0 million was recorded as additional
long-term debt and contributed to the Joint Venture.

 Benchmark
 
  Pursuant to an Asset Purchase Agreement among Benchmark, WinCup and James
River dated as of October 31, 1995, Benchmark and WinCup agreed to sell to
James River all of the assets of Benchmark's cutlery and straws business and
all of the assets of WinCup's thermoformed cup business, except for cash,
accounts receivable and prepaid assets. The only liabilities of Benchmark and
WinCup assumed by James River were obligations arising after the closing under
the assumed leases and assumed material contracts and vacation pay, holiday
pay and sick pay earned or accrued during 1995. The sales price was $51.0
million. The gain on the sale was approximately $2.0 million.
 
  The operations of Benchmark's cutlery and straws business and WinCup's
thermoformed cup business have been accounted for as discontinued operations
in the accompanying consolidated financial statements.
 
  Summary operating results for the operations sold, excluding the gain on
sale, are as follows (in thousands):

</TABLE>
 
 Property, Plant and Equipment
 
  Property, plant and equipment additions are recorded at cost and are
depreciated using the straight-line method over estimated useful lives which
range from 5 to 40 years. Leasehold improvements are amortized over the lesser
of their estimated useful lives or the term of the lease using the straight-
line method. Repair and maintenance costs are expensed as incurred.
 
 Supplies and Spare Mold Parts
 
  Supplies and spare mold parts include maintenance parts maintained in a
central stores location. When parts are needed at the various manufacturing
facilities, the parts are shipped and expensed in that current period.
 
 Organization Costs, Net
 
  Costs incurred to organize the Company have been capitalized and are being
amortized on a straight-line basis over five years. Such costs are net of
accumulated amortization of $1.1 million, $1.4 million and $1.7 million at
December 31, 1994 and 1995 and September 30, 1996, respectively.
 
 Financing Acquisition Costs
 
  Costs of $1.2 million incurred during 1996 in connection with obtaining
long-term financing have been capitalized, are included in other assets in the
accompanying financial statements and are being amortized on a straight-line
basis over the term of the Term Loan and Revolver (Note 3).
 
 Accounts Payable
 
  Included in accounts payable are amounts relating to outstanding checks of
$1.3 million, $1.5 million and $3.4 million at December 31, 1994, 1995, and
September 30, 1996, respectively.
 
 Revenue Recognition
 
  Revenue is recognized when goods are shipped. Sales are recorded gross of
any cash discounts. Any discounts subsequently taken by the customer are
recorded as a reduction to sales revenue.

               (INCLUDING NOTES APPLICABLE TO UNAUDITED PERIODS)
 
 Research and Development
 
  Research and development expenses are charged to expense as incurred.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Fair Value of Financial Instruments
 
  The estimated fair value of financial instruments has been determined by the
Company using the available market information and valuation methodologies.
Considerable judgment is required in estimating fair values. Accordingly, the
estimates may not be indicative of the amounts the Company could realize in a
current market exchange.
 
  The carrying values of cash, accounts receivable, accounts payable and
accrued liabilities approximate fair value due to the short-term maturities of
these instruments.
 
  The carrying amounts of the Company's bank term loans, line of credit and
mortgage note payable approximate fair value because they have variable
interest rates based on either prime rate or LIBOR.
 
  The carrying values of noninterest-bearing subordinated promissory notes A,
B and C approximate their fair values since they have been discounted using
the Company's incremental borrowing rate, which approximates the prime rate.
 
  The carrying values of subordinated promissory notes D, E and F approximate
their fair values as they bear interest at rates based on the prime rate.
 
 Recently Issued Accounting Standards
 
  Statement of Financial Accounting Standards (SFAS) No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of, which was adopted by the Company in 1996, did not have a material effect
on the Company's financial position or its results of operations upon
adoption. SFAS No. 123, Accounting for Stock-Based Compensation, is required
to be adopted by the Company in 1996. Pursuant to the provisions of SFAS No.
123, the Company will continue to account for transactions with its employees
pursuant to Accounting Principles Board Opinion No. 25, Accounting for Stock
Issued to Employees. Therefore, this statement is not expected to have a
material effect on the Company's financial position or its results of
operations when adopted.
 
 Unaudited Interim Consolidated Financial Statements
 
  The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for
interim financial information. In the opinion of management, all adjustments
(which include only normal recurring adjustments) necessary to present fairly
the financial position, results of operations and cash flows for all periods
presented have been made.

 Litigation
 
  The Company is involved in various legal actions arising in the normal
course of business. After taking into consideration legal counsel's evaluation
of such actions, management believes that these actions will not have a
material effect on the Company's financial position or results of operations.
 
  In July 1996, StyroChem (defined below) filed suit in the United States
District Court for the Northern District of Texas against James River for
breach of a supply contract between StyroChem and James River. The contract in
question required James River to purchase from StyroChem all of the expandable
polystyrene bead (EPS) requirements for its foam operations through February
1999, provided that the material satisfied certain product specifications.
Because the product supplied by StyroChem did not meet such specifications,
James River ceased purchasing EPS from StyroChem and did not assign the
contract to the Joint Venture in connection with its formation. The Joint
Venture agreed to indemnify James River for certain liabilities relating to
the failure of James River to assign the contract in question to the Joint
Venture and the Joint Venture has assumed the defense of such litigation,
subject to certain reservations

               (INCLUDING NOTES APPLICABLE TO UNAUDITED PERIODS)
of rights. The lawsuit has been stayed pending the outcome of the acquisition
(see Note 11), and management believes the lawsuit will be dismissed with
prejudice following the consummation of the acquisition. However, in the event
the StyroChem acquisition is not consummated, management does not believe the
ultimate outcome of the lawsuit will have a material effect on the Company's
financial position or results of operations.
 
 Letters of Credit
 
  The Company maintained letters of credit to support various self-insurance
programs in place through December 31, 1994. Letters of credit outstanding
totaled approximately $2.2 million as of December 31, 1994.
 
 Supply Agreement
 
  The Company is committed under a purchase agreement to buy from StyroChem
all of the EPS requirements for the former WinCup plants up to 40 million
pounds of EPS annually plus 75% of those plants' annual requirements in excess
of 40 million pounds at prevailing market prices. The agreement is for an
eight-year period ending February 2000, with options for yearly extensions
thereafter. The Company is currently negotiating to acquire StyroChem. (See
Note 11).
 
(5) REDEEMABLE CONVERTIBLE PREFERRED STOCK AND STOCKHOLDERS' EQUITY:
 
  The Company is authorized to issue up to 11,650 shares of voting common
stock, 5,650 shares of nonvoting common stock and 2,000 shares of redeemable
convertible preferred stock. At September 30, 1996, there are 6,000 shares of
voting common stock, 245 shares of nonvoting common stock and 2,000 shares of
redeemable convertible preferred stock outstanding. All shares have a par
value of $.10.
 
  In January 1996, the holder of the redeemable convertible preferred stock
agreed to modify the optional and mandatory redemption terms of such stock.
Pursuant to the modifications, the Company may at its option at any time
through January 20, 1999, redeem all of the outstanding redeemable convertible
preferred stock for an aggregate price of $2.0 million. On and after January
20, 1999, the holders of the outstanding redeemable convertible preferred
stock have the right to require the Company to redeem all such shares for an
aggregate price of $3.0 million. If the Company fails to pay the mandatory
redemption price, the outstanding redeemable convertible preferred stock is
converted into an unsecured promissory note in an amount equal to the
mandatory redemption price plus interest at 10% per annum. All accrued and
unpaid interest and principal are due two years from the date of the note. The
note shall not be subordinated to any other obligation of the Company.
 
  Prior to the modification of the optional and mandatory redemption terms,
the mandatory redemption price was $3,500 per share which was increased by a
7% return compounded annually. The redeemable convertible preferred stock has
been recorded outside of stockholders' equity at the $3.0 million mandatory
redemption price for all years presented (see Note 11).
 
  The redeemable convertible preferred stock is entitled to a $3,500
liquidating preference, which is increased each year the shares are
outstanding by a 7% compounded annual return, plus any accrued but unpaid
dividends that have been declared. There have been no dividends declared as of
September 30, 1996. The total liquidation value at September 30, 1996, is
approximately $9.6 million.
 
  On March 10, 1993, the Board of Directors, pursuant to a plan, granted
certain members of management the right to purchase up to 620 shares of the
Company's nonvoting common stock. Under

the terms of the grants, the participants could purchase stock for a period of
60 days from the date of grant at $800 per share, the fair value on that date,
for cash or through a note to be repaid through payroll deductions. During
1993, 245 shares were purchased under the plan for $180,000 in cash and
$15,000 in notes. No grants were made or shares purchased under the plan in
1994, 1995 or the nine month period ended September 30, 1996.
 
(6) RELATED PARTY TRANSACTION:
 
  During 1993, the Company paid $125,000 for management services to Trinity
Capital Partners, Inc. of which the President, sole director and majority
stockholder of the Company is the President, a director and sole shareholder.
Certain members of the Joint Venture's board of directors are employed by the
Company's primary legal counsel and the Company's investment banker. Amounts
paid to the law firm since the formation of the Joint Venture are
approximately $313,000. In connection with the formation of the Joint Venture,
the Company paid approximately $550,000 of investment banking fees to its
investment banker.
 
(7) RESTRUCTURING CHARGES:
 
  In connection with the formation of the Joint Venture, the Company accrued
approximately $855,000 in the nine months ended September 30, 1996 for certain
estimated future costs related to the consolidation and restructuring of
certain existing and acquired plants.
 
(8) INCOME TAXES:
 
  The Company accounts for income taxes under SFAS No. 109, Accounting for
Income Taxes. Under SFAS No. 109, deferred tax assets and liabilities are
recorded based on the differences between the financial statement and tax
bases of assets and liabilities at the tax rates in effect when these
differences are expected to reverse. There is no provision for taxes for the
years ended December 31, 1995, 1994 and 1993, as the Company generated net
operating losses for the years then ended.
 
  The provision for income taxes for each of the three years in the period
ended December 31, 1995 and for the nine month periods ended September 30,
1995 and 1996, is as follows (in thousands):

  The Company has recorded a valuation allowance with respect to the
alternative minimum tax and net operating loss carryforwards reflected as
deferred tax assets due to the uncertainty of their ultimate realization.
 
  The Company had net operating loss carryforwards of approximately $11.7
million at September 30, 1996. Net operating loss carryforwards expire through
2010. The Company also had approximately $18.8 million in alternative minimum
tax credit carryforwards at September 30, 1996, which are available
indefinitely.
 
(9) STOCK OPTION PLAN:
 
  The Company adopted the 1992 Stock Option Plan (the Plan), which provides
for the grant of non-qualified options to purchase shares of the nonvoting
common stock subject to certain limitations. Non-qualified stock options are
issuable only to eligible officers and employees of the Company. The Company
has reserved 1,249 shares of its nonvoting common stock for issuance under the
Plan.
 
  The per share exercise price of a stock option may not be less than 75% of
the fair market value of the nonvoting common stock, as determined by the
board of directors, on the date the option is granted. Such options may be
exercised only if the option holder remains continuously associated with the
Company from the date of grant to a date not less than three months prior to
the date of exercise. The exercise date of an option granted under the plan
cannot be later than ten years from the date of the grant. Any options that
expire unexercised or that terminate upon an optionee's ceasing to be employed
by the Company become available once again for issuance.
 
  The following summarizes the stock option activity under the Plan:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
               (INCLUDING NOTES APPLICABLE TO UNAUDITED PERIODS)
 
  The exercise price for all options granted to date is $3,350 per share,
which was the fair market value as determined by the board of directors on the
grant dates.
 
(10) EMPLOYEE BENEFIT PLAN:
 
  The Company sponsors a 401(k) savings and profit-sharing plan, which covers
all employees who have had at least 1,000 hours of service during any year.
The Company will match employee contributions up to 2.8% of an employee's
annual salary. The Company may also, at the discretion of the board of
directors, elect to make a profit-sharing contribution. There have been no
profit-sharing contributions for the three years in the period ended December
31, 1995, or for the nine months ended September 30, 1996. Employer matching
contributions to the plan amounted to approximately $269,000, $111,000,
$99,000 and $318,000 for the years ended December 31, 1993, 1994 and 1995 and
the nine months ended September 30, 1996.
 
(11) SUBSEQUENT EVENTS:
 
 Senior Note Offering
 
  On December 5, 1996, the Company completed a $100.0 million senior note
offering. Net proceeds to the Company from the offering were used to (i) repay
existing indebtedness, including amounts outstanding under the Term Note,
Revolver, the various subordinated notes and the mortgage note payable, (ii)
acquire James River's interest in the Joint Venture, (iii) redeem the
outstanding redeemable convertible preferred stock and warrants, (iv) finance
the StyroChem Acquisition (discussed below) and (v) provide working capital.
It is expected that $6.0 million of the subordinated notes payable will be
redeemed at 75% of their face value and the accrued interest on the notes will
be forgiven as they will be redeemed within certain timeframes as specified in
the Agreement. In addition, it is expected that James River's interest in the
Joint Venture will be acquired for $16.6 million. The difference between the
actual price paid to acquire James River's interest and the $17.7 million
currently recorded in the financial statements will reduce the value of the
original purchase price allocated to property, plant and equipment.
 
 StyroChem Acquisition
 
  On December 5, 1996, the Company acquired all of the issued and outstanding
capital stock of and other equity interests in SP Acquisition Co. (StyroChem),
a Delaware corporation, for an aggregate cash purchase price of approximately
$29.0 million plus $2.0 million of assumed indebtedness and consulting
payments. Pursuant to the Stock Purchase Agreement (the Agreement), the
purchase price is subject to adjustment based on the change in StyroChem's net
working capital, as defined in the Agreement, between August 3, 1996, and the
closing date. StyroChem is a manufacturer of EPS, which is the primary raw
material used in the production of foam cups and containers.
 
(12) UNAUDITED PRO FORMA FINANCIAL INFORMATION:
 
  The following unaudited pro forma information presents a summary of
consolidated results of operations as if the acquisition of J. R. Cup had
occurred at the beginning of each respective period, with adjustments to give
effect to amortization of financing fees, interest expense on acquisition debt
and certain other adjustments. The pro forma financial information is not
necessarily indicative of the results of operations as they would have been
had the transactions been effected on the assumed date.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To James River Paper Company, Inc.
and Radnor Holdings Corporation:
 
  We have audited the accompanying balance sheets of J. R. CUP FOAM CONTAINER
OPERATIONS OF JAMES RIVER PAPER COMPANY, INC. (a Virginia corporation)
(formerly Handi-Kup Foam Container Operations of James River Paper Company,
Inc.), as of December 25, 1994 and December 31, 1995, and the related
statements of operations, changes in owner's investment and cash flows for
each of the three years in the period ended December 31, 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the J. R. Cup Foam
Container Operations of James River Paper Company, Inc. as of December 25,
1994 and December 31, 1995, and the results of its operations for each of the
three years in the period ended December 31, 1995, in conformity with
generally accepted accounting principles.

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

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

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

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

$781,000 at December 25, 1994 and December 31, 1995, respectively, has been
included in other long-term liabilities in the accompanying financial
statements.
 
 Revenue Recognition
 
  Revenue is recognized when goods are shipped. Sales are recorded net of
expected cash discounts.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Fair Value of Financial Instruments
 
  The estimated fair value of financial instruments has been determined by the
Company using the available market information and valuation methodologies.
Considerable judgment is required in estimating fair values. Accordingly, the
estimates may not be indicative of the amounts the Company could realize in a
current market exchange.
 
  The carrying values of accounts receivable, accounts payable and accrued
liabilities approximate fair values due to the short-term maturities of these
financial instruments.
 
(3) COMMITMENTS AND CONTINGENCIES:
 
  The Company leases certain facilities, vehicles and equipment over varying
periods. None of the agreements contain unusual renewal or purchase options.
As of December 31, 1995, future minimum rental payments under noncancelable
operating leases were as follows (in thousands):

  Rent expense totaled $2.2 million, $2.4 million and $2.4 million in 1993,
1994 and 1995, respectively.
 
 Litigation
 
  The Company is involved in various legal actions arising in the normal
course of business. After taking into consideration legal counsel's evaluation
of such actions, management believes that these actions will not have a
significant effect on the Company's financial position or results of
operations.
 
  In July 1996, StyroChem, the Company's primary supplier of expandable
polystyrene beads (EPS) filed suit in the United States District Court for the
Northern District of Texas against James River for breach of a supply contract
between StyroChem and James River. The contract in question required James

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

River to purchase from StyroChem all of the EPS requirements for its foam
operations through February 1999, provided that the material satisfied certain
product specifications. Because the product supplied by StyroChem did not meet
such specifications, James River ceased purchasing EPS from StyroChem and did
not assign the contract to the Joint Venture in connection with its formation.
The Joint Venture agreed to indemnify James River for certain liabilities
relating to the failure of James River to assign the contract in question to
the Joint Venture and the Joint Venture has assumed the defense of such
litigation, subject to certain reservations of rights. The lawsuit has been
stayed pending the outcome of a proposed acquisition of StyroChem by WinCup,
and management expects the lawsuit will be dismissed with prejudice following
the consummation of the acquisition. Management does not believe the ultimate
outcome of the lawsuit will have a material effect on the Company's financial
position or results of operations.
 
(4) RELATED PARTY TRANSACTIONS:
 
  Transactions with other James River locations are reflected as though they
were settled immediately as an addition to or a reduction of James River's
investment and there are no amounts due to or from James River at the end of
any period.
 
(5) INCOME TAXES:
 
  The Company has historically been included in the consolidated federal
income tax return and combined/unitary state income tax returns of James
River. No provision for income taxes has been reflected in the accompanying
financial statements as the Company has historically generated tax losses on a
standalone basis. Deferred income tax assets and liabilities have been
determined at the corporate level and have not been allocated on a standalone
basis. Because the Company is included in the James River consolidated federal
income tax return, net operating loss carryforwards, investment and other tax
credit carryforwards, if any, were utilized by James River. Accordingly, the
Company has no reportable net operating loss or tax credit carryforwards on a
standalone basis.

SP Acquisition Co.
Fort Worth, Texas
 
  We have audited the accompanying consolidated balance sheets of SP
Acquisition Co. and subsidiaries (the Company), as of April 1, 1995 and March
30, 1996 and the related consolidated statements of income, stockholders'
equity and cash flows for the years then ended. The consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on the consolidated financial
statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of SP Acquisition Co. and
subsidiaries as of April 1, 1995 and March 30, 1996 and the results of their
operations and their cash flows for the years then ended in conformity with
generally accepted accounting principles.
 
  On October 30, 1996, as discussed in Note 16, the Company's shareholders
entered into a definitive agreement with Radnor Holdings Corporation (Radnor)
whereby Radnor agreed to acquire all the issued and outstanding capital stock
of and equity interests in the Company, subject to certain conditions.

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

                                                                        24,166
                                                                      --------

</TABLE>
 
  The excess of the fair value of the net assets acquired was accounted for as
a reduction in the fair value allocated to property and equipment.
 
  Fiscal Year--The Company's fiscal year ends on the Saturday nearest March 31
of each year.
 
  Unaudited Interim Financial Statements--The Company's consolidated balance
sheet as of September 28, 1996, and the consolidated statements of income and
cash flows for the six month periods ended  September 30, 1995 and September
28, 1996 have been prepared by the Company without audit. In the opinion of
management, all adjustments (which include only normal, recurring adjustments)
necessary to present fairly the balance sheet of the Company at September 28,
1996 and the results of operations and cash flows of the Company for the six
month periods ended September 30, 1995 and September 28, 1996 have been made.
The results of operations for the interim periods are not necessarily
indicative of the results to be expected for the full year.

  Cash and Cash Equivalents--For the purposes of reporting cash flows, cash
and cash equivalents includes investments readily convertible to cash with
remaining maturities at date of purchase of three months or less.
 
  Financial Instruments--The Company's financial instruments under Statement
of Financial Accounting Standards No. 107, "Disclosure About Fair Value of
Financial Instruments," include cash and cash equivalents, accounts
receivable, accounts payable and long-term debt. The Company believes that the
carrying amounts of cash and cash equivalents, accounts receivable, accounts
payable and long-term debt to banks are a reasonable estimate of their fair
value because of the short-term maturities of such instruments or, in the case
of long-term debt to banks, because of the floating interest rates on such
long-term debt. The fair value and carrying value of notes payable to
stockholders were $1.5 million and $1.0 million, respectively, at March 30,
1996.
 
  Inventories--Inventories are valued at the lower of cost or market with cost
determined using the average cost method. Inventories consist of finished
goods, work-in-process and raw materials. Finished goods costs include raw
materials, direct labor and indirect production and overhead costs. The
Company provides an allowance for obsolescence based on management's
evaluation of future usefulness and salability of inventory.
 
  Property, Plant and Equipment--Property, plant and equipment are recorded at
cost. Depreciation is recorded using the straight-line method over the
estimated useful lives of the assets, as follows:

  Expenditures that result in the enhancement of the assets involved are
capitalized and maintenance and repair costs are expensed when incurred. Upon
sale or other disposition, any gain or loss is included in income.
 
  Property Held for Sale--Land and structures currently being offered for sale
are classified separately from property and equipment. These properties are
currently carried at fair value, which is lower than cost.
 
  Income Taxes--Federal income taxes have been computed in accordance with
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes," which requires income taxes to be accounted for under the liability
method. Income taxes are provided for the tax effects of transactions

reported in the financial statements and consist of taxes currently due plus
deferred income taxes related primarily to differences between the basis of
property, plant and equipment due to depreciation differences and to the
application of the purchase method of accounting for financial statement
purposes but not for tax purposes, and nondeductible asset and liability
reserves for tax purposes. The deferred tax assets and liabilities represent
the future tax return consequences of those differences, which will either be
taxable or deductible when the assets and liabilities are recovered or
settled. Deferred tax assets are evaluated based on the guidelines for
realization and may be reduced by a valuation allowance.
 
  Foreign Currency Translation--The assets and liabilities of the Company's
Canadian subsidiary, StyroChem International, Ltd., whose functional currency
is other than the U.S. dollar are translated at year-end exchange rates.
Revenue and expense accounts are translated using the weighted average
exchange rate during the periods. Translation gains and loses are not included
in determining net income but are accumulated in a separate component of
stockholders' equity, as is required by Statement of Financial Accounting
Standards No. 52, "Foreign Currency Translation."
 
  Research and Development--Research and development expenses are charged to
income as incurred. Total research and development expenses were approximately
$1.3 million and $1.6 million for the years ended April 1, 1995 and March 30,
1996, respectively, and approximately $1.3 million and $1.0 million for the
unaudited six month periods ended September 30, 1995 and September 28, 1996,
respectively.
 
  Accounting Estimates--The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
  Recently Issued Accounting Pronouncements--Statement of Financial Accounting
Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of," requires that long-lived assets and
certain identifiable intangibles to be held and used by an entity be reviewed
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Impairment is evaluated by
comparing future cash flows (undiscounted and without interest charges)
expected to result from the use of the asset and its eventual disposition to
the carrying amount of the asset. This new accounting principle is effective
for the Company's fiscal year ending March 29, 1997. The Company believes that
this new accounting principle will not have a material impact on its
consolidated financial position or results of operations.

  The Company's notes payable and long-term debt agreements contain certain
restrictive covenants. These covenants require that the Company meet certain
requirements such as a minimum current ratio, a minimum trailing twelve-months
operating cash flow, a minimum tangible net worth, a minimum fixed charge
coverage ratio, a maximum ratio of indebtedness to tangible net worth and
maximum dividend distributions. The Company was not in compliance with certain
of these covenants at April 1, 1995 and March 30, 1996, but subsequently
obtained a waiver or an amendment for these instances of noncompliance.
 
  Effective August 31, 1996, the bank term note and line of credit agreement
was amended to revise certain covenants and to extend the final maturities to
September 1, 1998. Under the terms of the loan

agreements, the Company has the option to designate the interest rate for
borrowings under the loan agreements using either a prime plus or London
Interbank Offering Rate (LIBOR) option. The interest rate for domestically
designated borrowings under the bank term note and the line of credit was
adjusted to prime plus 0.25% and prime, respectively. LIBOR designated

  The Company has established a valuation allowance for deferred tax assets of
the Company's Canadian subsidiary. The deferred tax assets represent primarily
the excess of the tax over the book basis of property, plant and equipment.
Because of the operating losses of this subsidiary, the Company has been
unable to determine that it is more likely than not that the net deferred tax
assets of this subsidiary will be realized. Should the Canadian subsidiary
become profitable in future periods, this valuation allowance may be reduced
or eliminated. The Company will continue to review this valuation allowance on
a quarterly basis and make adjustments as appropriate.
 
9. MAJOR SUPPLIER
 
  The Company has agreed to purchase a minimum of 67% of its styrene monomer
used in production from one supplier. The agreement, which is for a five year
period ending February 1999, and is renewable for successive annual terms,
provides for purchases at prevailing market-related prices and for favorable
payment terms.
 
  In connection with this agreement, the Company's majority shareholder
granted this supplier an option to purchase 51,000 shares of common stock held
by the shareholder at the fair market value, as defined, of such shares at the
date of exercise. This option, which is exercisable between March 1, 1997 and
February 28, 1999, also requires this supplier to offer to purchase all the
outstanding shares of the Company's common stock at date of exercise.
 
  During the years ended April 1, 1995 and March 30, 1996, the Company's
purchases from this supplier amounted to approximately $41.0 million and $42.8
million, respectively, and the balance payable to this supplier by the Company
as of April 1, 1995 and March 30, 1996 amounted to approximately $8.6 million
and $8.2 million, respectively. During the unaudited six month periods ended
September 30, 1995 and September 28, 1996, the Company's purchases from this
supplier amounted to approximately $21.4 million and $20.0 million,
respectively. As of September 28, 1996 (unaudited), the balance payable to
this supplier was approximately $11.8 million.

  UNAUDITED SIX MONTH PERIODS ENDED SEPTEMBER 30, 1995 AND SEPTEMBER 28, 1996
 
10. CONCENTRATION OF CREDIT RISK
 
  Financial instruments that potentially subject the Company to concentrations
of credit risk consist principally of accounts receivable. Generally, the
Company does not require collateral to support customer receivables. The
Company follows established credit inquiry and investigation procedures in an
attempt to minimize credit risk associated with customer receivables. The
Company has one related party customer, WinCup Holdings, L.P., a subsidiary of
Radnor Holdings Corporation, which accounted for more than 10% of sales in
both 1995 and 1996. Sales to this customer were approximately $24.0 million
and $23.0 million for the years ended April 1, 1995 and March 30, 1996,
respectively, and approximately $13.1 million and $9.6 million for the
unaudited six month periods ended September 30, 1995 and September 28, 1996,
respectively. As of April 1, 1995, March 30, 1996 and September 28, 1996
(unaudited), outstanding accounts receivable from this customer were
approximately $6.5 million, $4.2 million and $3.8 million, respectively.
 
11. EMPLOYEE BENEFIT PLAN
 
  The Company sponsors a tax-qualified defined contribution plan under Section
401(a) of the Internal Revenue Code covering all full-time employees in the
U.S. who have completed one year of service. This plan includes a 401(k)
arrangement pursuant to which participants may contribute, subject to certain
limitations, a percentage of their salary on a pretax basis. The Company
contributes a matching contribution with respect to the contributions made by
participants at a rate determined by the Board of Directors of the Company
each year. The Company's 401(k) matching contributions were $62,763 and
$64,674 for the years ended April 1, 1995 and March 30, 1996, respectively,
and $43,209 and $48,977 for the unaudited six month periods ended September
30, 1995 and September 28, 1996, respectively.
 
12. RELATED PARTY TRANSACTIONS

14. STOCKHOLDERS' EQUITY
 
  On February 25, 1994, the Company issued to its preferred stockholders
warrants to allow for the purchase of 25,313 shares (the "Warrant Shares") of
the Company's common stock at an exercise price of $.01 per share. The
warrants are not exercisable until the notes to stockholders (the Notes) are
repaid; however, they become immediately exercisable in full on the Company's
capital reorganization, merger or acquisition of the Company. The Warrant
Shares are subject to adjustment or cancellation upon the occurrence of
certain events; including the repayment of the Notes in advance of their
scheduled maturity. In addition, the terms of the warrants provide for
adjustments to the exercise price as a result of stock splits, dividends or
issuances. During 1995, warrants for 12,500 shares of common stock were
canceled as a result of early repayments or payments of certain of the Notes.
At April 1, 1995, March 30, 1996 and September 28, 1996 (unaudited), warrants
for 12,813 shares were outstanding, which expire at March 31, 1999.
 
15. COMMITMENTS AND CONTINGENCIES
 
  Supply Agreement--The Company is committed under a supply agreement to sell
to WinCup Holdings, L.P. all of WinCup's requirements for expandable
polystyrene for certain of its plants at sales prices based on prevailing
market prices for up to 40 million pounds annually, and no less than 75% of
the requirements for those plants in excess of 40 million pounds annually. The
agreement is for an eight-year period ending February 2000, with options for
annual extensions thereafter.

</TABLE>
 
  Rental expense under operating leases for the years ended April 1, 1995 and
March 30, 1996 was approximately $170,000 and $329,000, respectively, and
approximately $215,000 and $158,000 for the unaudited six month periods ended
September 30, 1995 and September 28, 1996, respectively.
 
  Other--The Company is involved in various legal proceedings arising in the
normal course of business. Management believes the outcome of these matters
will not materially affect the consolidated financial position or results of
operations of the Company.
 
  Like other chemical manufacturers, the Company's operations are subject to
extensive and rapidly changing federal and state environmental regulations,
including original and renewal permit application proceedings in connection
with its business operations. These environmental laws and regulations may
require the Company to take action in the future to correct the effects of
prior environmental issues at the Company's facilities, if any. In connection
with the Company's acquisition of its business operations from KCTC on
February 25, 1994, as discussed on Note 1, the Company was indemnified by KCTC
as to environmental matters existing prior to the acquisition date. The extent
of loss related to environmental matters depends on a number of factors,
including technological developments and changes in environmental laws, among
other. Based on currently known facts, management believes that any
environmental costs the Company may incur would not have a material adverse
effect on the consolidated financial position or results of operations of the
Company.
 
  The Company participates in a self-insurance program that provides for the
payment of employee health claims. The program provides for specific excess
loss reinsurance for aggregate claims greater than a specified amount for any
one claimant. The Company accrues the estimated liabilities for the ultimate
costs of both reported claims and incurred but not reported claims.
 
16. SUBSEQUENT EVENT
 
  On October 30, 1996, the Company's shareholders entered into a definitive
agreement with Radnor Holdings Corporation (Radnor) whereby Radnor agreed to
acquire all the issued and outstanding shares of capital stock of and other
equity interests in the Company for an aggregate purchase price of $31.0
million, subject to satisfactory resolution of environmental matters and
financing.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Radnor Holdings Corporation (the "Company"), WinCup Holdings, Inc., SP
Acquisition Co. and Radnor Management, Inc. are Delaware corporations.
Subsection (b)(7) of Section 102 of the Delaware General Corporation Law (the
"DGCL"), enables a corporation in its original certificate of incorporation or
an amendment thereto to eliminate or limit the personal liability of a
director to the corporation or its stockholders for monetary damages for
violations of the director's fiduciary duty, except (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, (iii) pursuant to Section 174 of the DGCL
(providing for liability of directors for unlawful payment of dividends or
unlawful stock purchases or redemptions) or (iv) for any transaction from
which a director derived an improper personal benefit. Article Sixth of the
Company's Restated Certificate of Incorporation, Article Seventh of the
Certificate of Incorporation of WinCup Holdings, Inc., Article VII of the
Certificate of Incorporation of SP Acquisition Co., and Article Seventh of the
Certificate of Incorporation of Radnor Management, Inc. have eliminated the
personal liability of directors to the fullest extent permitted by Subsection
(b)(7) of Section 102 of the DGCL.
 
  Subsection (a) of Section 145 of the DGCL empowers a corporation to
indemnify any director or officer, or former director or officer, who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation)
by reason of the fact that such person is or was a director or officer of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred in connection with such action, suit or proceeding
provided that such director or officer acted in good faith in a manner
reasonably believed to be in, or not opposed to, the best interests of the
corporation, and, with respect to any criminal action or proceeding, provided
further that such director or officer had no reasonable cause to believe his
conduct was unlawful.
 
  Subsection (8) of Section 145 empowers a corporation to indemnify any
director or officer, or former director or officer, who was or is a party or
is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the corporation to procure a judgment in
its favor by reason of the fact that such person acted in any of the
capacities set forth above, against expenses (including attorneys' fees)
actually and reasonably incurred in connection with the defense or settlement
of such action or suit provided that such director or officer acted in good
faith and in a manner he reasonably believed to be in, or not opposed to, the
best interests of the corporation, except that no indemnification may be made
in respect of any claim, issue or matter as to which such director or officer
shall have been adjudged to be liable to the corporation unless and only to
the extent that the Court of Chancery or the court in which such action or
suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all of the circumstances of the case,
such director or officer is fairly and reasonably entitled to indemnity for
such expenses which the Court of Chancery or such other court shall deem
proper.
 
  Section 145 further provides that to the extent a director or officer of a
corporation has been successful in the defense of any action, suit or
proceeding referred to in subsections (a) and (b) or in the defense of any
claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith; that indemnification and advancement of expenses
provided for, by, or granted pursuant to, Section 145 shall not be deemed
exclusive of any other rights to which the indemnified party may be entitled;
and empowers the
 
                                     II-1
<PAGE>
 
corporation to purchase and maintain insurance on behalf of any person who is
or was a director or officer of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against any liability asserted against him or incurred by him in any such
capacity, or arising out of his status as such, whether or not the corporation
would have the power to indemnify him against such liabilities under Section
145.
 
  Article 6 of the By-Laws of the Company, WinCup Holdings, Inc. and Radnor
Management, Inc. and Article VI of the Bylaws of SP Acquisition Co. state that
the corporations shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending, or completed action,
suit or proceeding, by reason of the fact that he is or was a director,
officer or employee of the corporation, or is or was serving at the request of
the corporation as a director, officer or employee of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit
or proceeding if he acted in good faith and in a manner he reasonably believed
to be in, or not opposed to the best interests of, the corporation.
 
  WinCup Holdings, L.P. is a Delaware limited partnership. Section 17-109 of
Delaware Revised Limited Partnership Act provides authority for limited
partnerships to indemnify, subject to such standards and restrictions as are
set forth in the partnership agreement, any partner or other person from and
against any and all claims and demands. Section 3.3.2 of the Amended and
Restated Partnership Agreement of WinCup Holdings, L.P. provides that the
partnership shall indemnify each partner, its shareholders, employees, agents
and affiliates with respect to claims or proceedings arising from or relating
to the partnership, provided that the same were not the result of actions by
the party seeking indemnification taken in bad faith and/or in violation of
the partnership agreement.
 
  Styrochem International, Inc. is a Texas corporation. Article 2.02-1 of the
Texas Business Corporation Act, as amended (the "TBCA"), empowers a Texas
corporation to indemnify its directors, officers, employees and agents in a
variety of circumstances and to purchase and maintain liability insurance for
those persons. Article 2.02-1.B. generally provides a corporation may
indemnify a person who was or is a director if it is determined that the
person (i) conducted himself in good faith, (ii) reasonably believed his
conduct was in the corporation's best interests for actions in his official
capacity or reasonably believed his conduct was at least not opposed to the
corporation's best interests for all other cases, and (iii) in the case of a
criminal proceeding, had no reasonable cause to believe his conduct was
unlawful. A person may be entitled to indemnification against judgments,
penalties (including excise and similar taxes), fines, settlements, and
reasonable expenses actually incurred by the person in connection with a
threatened, pending or completed civil or criminal proceeding or inquiry. A
director may not be indemnified in respect of any proceeding in which he is
found liable on the basis that a personal benefit was improperly received by
him or in which he is found liable to the corporation. Any indemnification or
advance of expenses to a director in accordance with Article 2.02-1 must be
reported to the shareholders with or before the notice of waiver of notice of
the next shareholders' meeting or with or before the next submission of a
consent without a meeting and, in any case, within twelve months following the
date of the indemnification or advance.
 
  A determination whether indemnification is permissible under Article 2.02-
1.B. must be made by a majority vote of a quorum consisting of directors who,
at the time of the vote, are not named defendants or respondents in the
proceeding. If such a quorum cannot be obtained, the determination may be made
by a majority vote of a committee of the board of directors designated to act
so long as the members of the committee are not named defendants or
respondents, by a special legal counsel selected by the directors, or by a
shareholders' vote that excludes the shares held by directors who are named
defendants or respondents. Article 2.02-I.H. provides that a corporation shall
indemnify a director against reasonable expenses incurred in connection with a
proceeding in which he is a named defendant or respondent
 
                                     II-2
<PAGE>
 
because he is or was a director if he has been wholly successful, on the
merits or otherwise, in the proceeding.
 
  An officer of a Texas corporation is also entitled to seek indemnification
from the corporation to the same extent as a director and shall receive
indemnification for reasonable expenses incurred in connection with a
proceeding in which he is a named defendant or respondent because he is or was
an officer if he has been wholly successful in the proceeding. Article 2.02-1
also permits a Texas corporation to indemnify and advance expenses to
employees or agents, or to persons who are not or were not officers, employees
or agents of the corporation but who are or were serving as a functionary of
another enterprise at the request of the corporation, to the same extent that
it may indemnify and advance expenses to directors.
 
  Although Article 2.02-1.U. generally permits a Texas corporation's articles
of incorporation to contain provisions restricting the circumstances under
which the corporation is required or permitted to indemnify a person,
Styrochem International, Inc.'s Articles of Incorporation do not contain such
a restriction.
 
  StyroChem International, Ltd. is subject to the Quebec Companies Act (the
"QCA"). Section 123.87 of the QCA provides that a corporation shall assume the
defense of any officer, director, employee or agent of the corporation in any
proceeding brought against such person in connection with any act done by such
person in the exercise of his or her duties for the corporation, and shall pay
damages, if any, resulting from such act, unless such person has committed a
grievous offense or a personal offense separable from the exercise of his or
her duties; provided however, that in a penal or criminal proceeding the
corporation shall assume the expenses of such person only if he or she had
reasonable grounds to believe that his or her conduct was in conformity with
the law, or if he or she is freed or acquitted.
 
  Article 20 of StyroChem International, Ltd.'s by-laws states that: "Every
director and officer of StyroChem International, Ltd. shall be deemed to have
assumed office on the express understanding and agreement and condition that
he and his heirs, executors and administrators and estate and effects
respectively shall from time to time and at all times be indemnified and saved
harmless out of the funds of StyroChem International, Ltd. from and against
all costs, charges and expenses whatsoever which such director or officer
sustains or incurs in or about any action, suit or proceeding which is
brought, commenced or prosecuted against him or them for or in respect of any
act, deed, matter or thing whatsoever made, done or permitted by him in or
about the execution of the duties of his office, and also from and against all
other costs, charges and expenses which he sustains or incurs in or about or
in relation to the affairs thereof, except such costs, charges or expenses as
are occasioned by his own willful neglect or default."
 
  Article 20 of StyroChem International, Ltd.'s by-laws further states that:
"The directors of StyroChem International, Ltd. may cause the company to give
indemnities to any director or other person who has undertaken or is about to
undertake on behalf of the company or any corporation controlled by it and to
secure such director or other person against loss by mortgage and charge upon
the whole or any part of the real and personal property of the company by way
of security, and any action taken by the directors under this paragraph shall
not require approval or confirmation by the shareholders."

          B.   Common Stock

               Except as set forth below, each share of Common Stock issued and

General Corporation Law, as amended, the holders of shares of Nonvoting Common
Stock and Class B Nonvoting Common Stock shall not be entitled to vote on any
matter submitted to the stockholders of the Corporation for a vote.

shall from time to time be sufficient to effect conversions of the shares of
Nonvoting Common Stock which may be issued from time to time."

however, that the date for such meeting as may be designated by the Board of
Directors must be within 13 months from the later of the date on which the
Corporation has been organized or the date on which the last annual meeting of

state.

     Section 2.3 Special meetings of the stockholders, for any purpose or 
purposes, may be called by the President and shall be called by him or the

represented at any meeting, the chairman of the meeting or the holders of a 
majority of the shares of the stock entitled to vote who are present, in person 
or by proxy, may adjourn the meeting to another place, date or time. When a 
meeting is so adjourned, written notice need not be given of the adjourned 
meeting if the place, date and time thereof are announced at the meeting at 
which the adjournment is taken; provided, however, that if the date of any 
adjourned meeting is more than 30 days after the date for which the meeting was
originally noticed, or if a new record date is fixed for the adjourned meeting,
written notice of the place, date, and time of the adjourned meeting shall be
given in conformity herewith. At any adjourned meeting, any business may be

of stock entitled to vote which is registered in his name on the record date for
the meeting, except as otherwise provided herein or required by law. All
elections of directors by the stockholders shall be by written ballot, and shall
be determined by a plurality of votes cast. All other voting need not be by

which, by express provision of law or of the Certificate of Incorporation or of
these Bylaws, a different vote is required.    

     Section 2.7  At least 10 days before every meeting of stockholders, the 
officer who has charge of the stock ledger of the Corporation shall prepare a 
complete list of the stockholders entitled to vote at such meeting, arranged in 
alphabetical order, and showing the address of each stockholder and the number 
of shares registered in the name of each stockholder. Such list shall be open to

stockholder of the Corporation who is present. The stock ledger of the 
Corporation shall be the only evidence as to the identities of the stockholders 
entitled to examine the list of stockholders required by this Section 2.7 or to 
vote in person or by proxy at any meeting of stockholders.

of Election to act at any meeting of the stockholders or any adjournment
thereof. Judges of Election need not be stockholders, and no person who is a
candidate for corporate office shall act as a Judge of Election. If three Judges
of Election are appointed, such Judges of Election shall act by majority vote.
Judges of Election shall do all acts as are necessary and proper to conduct the
election or vote and all such other acts as may be prescribed by law with
fairness to all stockholders. If requested to do so by the Board of Directors or
the chairman of the meeting at which Judges of Election act, such Judges of
Election shall make a written report of any matter determined by them and shall
execute a certificate as to any fact found by them.

including such regulation of the manner of voting and the conduct of discussion
as he shall deem to be fair and equitable.

     Section 2.10 The stockholders may participate in any meeting by means of
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other, and such participation
shall constitute presence in person at such meeting.

     Section 2.11 Unless otherwise required by the Certificate of Incorporation 
of the Corporation, any action required or permitted to be taken at any meeting 
of the stockholders may be taken without a meeting, without prior notice and 
without a vote, if a written consent setting forth the action so taken shall be 
signed by the holders of outstanding stock having not less than the minimum 
number of votes that would be necessary to authorize or take such action at a 
meeting at which all shares entitled to vote thereon were present and voted. 
Prompt notice of the taking of any corporate action without a meeting by less 
than unanimous written consent shall be given in conformity herewith to those 
stockholders who have not consented thereto in writing.

expressly conferred upon the Board of Directors by these Bylaws, the Board of
Directors may exercise all powers of the Corporation and perform all lawful acts
as are not required to be exercised or performed by the stockholders pursuant to
law, the Certificate of Incorporation of the Corporation or these Bylaws.

     Section 3.2  Directors shall be natural persons who need not be

directors is increased between annual meetings of the stockholders, a majority
of the directors then in office shall have the power to elect such new directors
who shall serve until the next annual meeting of stockholders and until their
successors are duly elected and qualified. Any decrease in the authorized number
of directors shall not become effective until the expiration of the term of the
directors then in office unless, at the time of such decrease, there shall be

                                      -7-
<PAGE>
 
vacancies on the Board of Directors which are being eliminated by such decrease.

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

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

     Section 3.5  Regular meetings of the Board of Directors shall be held 
without call or notice at such time and place as shall from time to time be

the President or the Secretary on the written request of a majority of the
directors then in office, and shall be held at such place, on such date and at
such time as they or he shall designate. Notice of the place, time and date of
each such special meeting shall be given to each director by whom it is not
waived by mailing written notice to each director not less than 2 days before
the meeting or by telegram or telephone not

                                      -8-
<PAGE>
 
less than 48 hours before the meeting. Notice of special meetings of the Board
of Directors need not state the purpose thereof, except as otherwise expressly
provided by law, by the Certificate of Incorporation of the Corporation, or by
these Bylaws. Any and all business may be transacted at a special meeting,
unless otherwise indicated in the notice thereof or provided by law, by the
Certificate of Incorporation of the Corporation or by these Bylaws.

     Section 3.7 Members of the Board of Directors or any committee thereof may 
participate in any meeting of such Board or committee by means of conference 
telephone or similar communications equipment by means of which all persons 
participating in the meeting can hear each other, and such participation shall 
constitute presence in person at such meeting.

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

Directors or committee, as the case may be, consent thereto in writing and such 
consent is filed with the minutes of proceedings of the Board of Directors or 
committee thereof.

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

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

authority of the Board of Directors to declare a dividend or to authorize the 
issuance of stock if the resolution which designates the committee or a 
supplemental resolution of the Board of Directors shall so provide. In the 
absence or disqualification of any member of any committee and any alternate

meeting and not disqualified from voting, whether or not he or they constitute a

writing, and such writing is filed with the minutes of the proceeding of such 
committee.
    
          Section 4.5 Each committee may determine the procedural rules for 
meeting and conducting its business and shall act in accordance therewith, 
except as otherwise provided by law, by the Certificate of Incorporation of the

     Section 5.4  Each officer shall hold office until his successor is duly 
elected and qualified or until his earlier death, resignation, retirement or 
removal. Any officer elected or appointed by the Board of Directors may be

Directors or by the President, taking proper vouchers for such disbursements, 
and shall render to the Board of Directors an account of all such transactions 
and of the financial condition of the Corporation, at such times as the Board of
Directors may require. The Treasurer shall also perform such other duties as the

                           ARTICLE 6 INDEMNIFICATION
                                     ---------------

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

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

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

                                     -17-
<PAGE>
 
the circumstances because he has met the applicable standard of conduct set 
forth in Section 6.1 or Section 6.2 of this Article 6, as the case may be. Such 
determination shall be made (i) by the Board of Directors by a majority vote of 
a quorum consisting of directors who are not parties to such action, suit or 
proceeding, (ii) if such a quorum is not attainable, or, even if attainable, if 
a majority vote of a quorum of disinterested directors so directs, by 
independent legal counsel in a written opinion or (iii) by the stockholders. To 
the extent, however, that a director, officer or employee of the Corporation has
been successful on the merits or otherwise in defense of any action, suit or 
proceeding described above, or in defense of any claim, issue or matter therein,
he shall be indemnified against expenses (including attorneys' fees) actually 
and reasonably incurred by him in connection therewith, without the necessity of
authorization in the specific case.

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

                                     -18-
<PAGE>
 
professionally or expertly competent to prepare such records or books of 
account), or on information supplied to him by the officers of the Corporation 
or another enterprise in the course of their duties, or on the advice of legal 
counsel for the Corporation or another enterprise or on information or records 
given or reports made to the Corporation or another enterprise by an independent
certified public accountant or by an appraiser or other expert selected with 
reasonable care by the Corporation or another enterprise. The term "another 
enterprise" as used in this Section 6.4 shall mean any other corporation or any 
partnership, joint venture, trust or other entity of which such person is or was
serving at the request of the Corporation as a director, officer or employee. 
The provisions of this Section 6.4 shall not be deemed to be exclusive or to 
limit in any way the circumstances in which a person may be deemed to have met 
the applicable standard of conduct set forth in Section 6.1 or 6.2 of this 
Article 6, as the case may be.

      Section 6.5 Notwithstanding any contrary determination in the specific 
case under Section 6.3 of this Article 6, and notwithstanding the absence of any
determination thereunder, any director, officer or employee may apply to any 
court of competent jurisdiction in the State of Delaware for indemnification to 
the extent otherwise permissible under Sections 6.1 and 6.2 of this Article 6. 
The basis of such indemnification by a court shall be a determination by such 
court that indemnification of the director, officer or employee is proper in the
circumstances

                                     -19-
<PAGE>
 
because he has met the applicable standards of conduct set forth in Section 6.1 
or 6.2 of this Article 6, as the case may be. Notice of any application for 
indemnification pursuant to this Section 6.5 shall be given to the Corporation 
promptly upon the filing of such application.
    
        Section 6.6  Expenses incurred in defending or investigating a 
threatened or pending action, suit or proceeding may be paid by the Corporation 
in advance of the final disposition of such action, suit or proceeding as 
authorized by the Board of Directors upon receipt of an undertaking by or on
behalf of the director, officer or employee to repay such amount if it shall 
ultimately be determined that he is not entitled to be indemnified by the 
Corporation as authorized in this Article 6.     

        Section 6.7  The indemnification and advancement of expenses provided 
by, or granted pursuant to, the other sections of this Article 6 shall not be 
deemed exclusive of any other rights to which those seeking indemnification or 
advancement of expenses may be entitled under any by-law, agreement, contract, 
vote of stockholders or disinterested directors or pursuant to the direction 
(howsoever embodied) of any court of competent jurisdiction or otherwise, both
as to action in his official capacity and as to action in another capacity while
holding such office, it being the policy of the Corporation that indemnification
of, and advancement of expenses to, the persons specified in Section 6.1 and 6.2
of this Article 6 shall be made

                                     -20-
<PAGE>
 
to the fullest extent permitted by law. To this end, the provisions of this 
Article 6 shall be deemed to have been amended for the benefit of such persons 
effective immediately upon any modification of the General Corporation Law of 
the State of Delaware which expands or enlarges the power or obligation of 
corporations organized under such law to indemnify, or advance expenses to, such
persons. The provisions of this Article 6 shall not be deemed to preclude the 
indemnification of, or advancement of expenses to, any person who is not 
specified in Section 6.1 or 6.2 of this Article 6 but whom the Corporation has 
the power or obligation to indemnify, or to advance expenses for, under the 
provisions of the General Corporation Law of the State of Delaware or otherwise.
The indemnification and advancement of expenses provided by, or granted pursuant
to, this Article 6 shall, unless otherwise provided when authorized or ratified,
continue as to a person who has ceased to be a director, officer or employee and
shall inure to the benefit of the heirs, executors and administrators of such 
person.      

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

                                     -21-
<PAGE>
 
power or the obligation to indemnify him against such liability under the 
provisions of this Article 6.
     Section 6.9 For purposes of this Article 6, references to the "Corporation"
shall include, in addition to the resulting corporation, any constituent 
corporation (including any constituent of a constituent) absorbed in a 
consolidation or merger which, if its separate existence had continued, would 
have had the power and authority to indemnify its directors, officers and 
employees, so that any person who is or was a director, officer or employee of 
such constituent corporation, or is or was serving at the request of such 
constituent corporation as a director, officer or employee of another 
corporation, partnership, joint venture, trust or other enterprise, shall stand
in the same position under the provisions of this Article 6 with respect to the 
resulting or surviving corporation as he would have with respect to such 
constituent corporation if its separate existence had continued.

                               ARTICLE 7  STOCK
                                          -----

     Section 7.1 The certificates representing shares of stock of the 
Corporation shall be numbered and shall be entered in the books of the 
Corporation as they are issued. Each stockholder shall be entitled to a 
certificate exhibiting such stockholder's name and the number of shares held by 
such stockholder, which certificate shall be signed by the President or any 
Vice-President, and by the Treasurer or the Secretary or any Assistant
Secretary. Any or all of the signatures on such


                                      -22-

<PAGE>
 
certificate may be a facsimile. In case any officer, transfer agent or registrar
who has signed or whose facsimile signature has been placed upon a certificate 
shall have ceased to be such officer, transfer agent or registrar before such 
certificate is issued, such certificate may be issued by the Corporation with 
the same effect as if he were such officer, transfer agent or registrar at the 
date of issue.

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

        Section 7.3 In order that the Corporation may determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any 
adjournment thereof, or to express consent to corporate action in writing 
without a meeting, or entitled to receive payment of any dividend or other 
distribution or allotment of any rights, or entitled to exercise any rights in 
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date, 
which shall not be more than 60 nor less than 10 days before the date of such 
meeting nor more that 60 days prior to any other action. A determination of 
stockholders of record entitled to notice of or to vote at a meeting of 
stockholders shall apply to any adjournment of the

                                     -23-

<PAGE>
 
meeting; provided, however, that the Board of Directors may fix a new record 
date for the adjourned meeting.

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

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

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

                               ARTICLE 8 NOTICES
                                         -------

     Section 8.1 Whenever notice is required to be given to any director, 
committee member, officer, stockholder, employee or

                                     -24-
<PAGE>
 
agent, whether pursuant to law, the Certificate of Incorporation of the 
Corporation or these Bylaws, it shall not be construed to mean personal notice, 
but such notice may be given, in the case of stockholders, in writing, by 
depositing the same in the mail, postage prepaid, addressed to such stockholder 
at his last known address as the same appears on the books of the Corporation, 
and, in the case of directors, committee members, officers, employees and 
agents, by telephone, or by mail, postage prepaid, or by prepaid telegram at his
last known address as the same appears on the books of the Corporation. All 
notices shall be deemed to be given when mailed, telegraphed or telephoned.

         Section 8.2  Whenever notice is required to be given to any 
stockholder, director, committee member, officer, employee or agent, whether 
pursuant to law, the Certificate of Incorporation of the Corporation or these 
Bylaws, a written waiver thereof, signed by the person entitled to notice, 
whether before or after the time stated therein, shall be deemed equivalent to 
notice. Attendance of a person at a meeting shall constitute a waiver of notice 
of such meeting, except as otherwise provided by law. Neither the business to be
transacted at, nor the purpose of, any regular or special meeting of the 
stockholders, directors, or members of a committee of directors need be 
specified in any written waiver of notice unless so required by the Certificate 
of Incorporation of the Corporation or by these Bylaws.

declared by the Board of Directors at any regular or special meeting, pursuant 
to law, and subject to the provisions of the Certificate of Incorporation of the
Corporation. Dividends may be paid in cash, in property or in shares of the 
capital stock of the Corporation.

      Section 9.2   Before payment of any dividend, the Board of Directors may
set aside, out of any funds of the Corporation available for dividends, such
sums as the Board of Directors may deem proper as a reserve fund to meet
contingencies, to equalize dividends, to repair or maintain any property of the
Corporation, or for such other purposes as the Board of Directors may deem to be
in the best interests of the Corporation, and the Board of Directors may reduce
or abolish any such reserve in the manner in which it was created.

evidenced by the corporate seal.

     Section 10.3  The fiscal year of the Corporation shall be as determined by 
the Board of Directors.

     Section 10.4  All checks or demands for money and notes of the Corporation

time to time designate.

     Section 10.5  The Board of Directors shall determine from time to time 
whether, when and under what conditions and regulations, the books and records 
of the Corporation (except such as may by statute be specifically open to 
inspection) shall be open to the inspection of the stockholders, and the 
stockholders' rights in this respect are and shall be restricted and limited 
accordingly.

     Section 10.6  At each annual meeting of the stockholders of the
Corporation, the Board of Directors shall present a full and clear statement of
the business and affairs of the Corporation for the preceding year.

majority of all of the issued and outstanding shares of stock entitled to vote 
at the meeting, present in person or by proxy, shall constitute a quorum for 
all purposes, except to the extent that the presence of a larger number of 
stockholders may be required by law, by the Certificate of Incorporation of the 
Corporation or by these Bylaws. If a quorum shall fail to be present or 
represented at any meeting, the chairman of the meeting or the holders of a 
majority of the shares of the stock entitled to vote who are present, in person 
or by proxy, may adjourn the meeting to another place, date or time. When a 
meeting is so adjourned, written notice need not be given of the adjourned 
meeting at which the adjournment is taken; provided, however, that if the date 
of any adjourned meeting is more than 30 days after the date for which the 
meeting was originally noticed, or if a new record date is fixed for the 
adjourned meeting, written notice of the place, date, and time of the adjourned 
meeting shall be given in conformity herewith. At any adjourned meeting, any 
business may be transacted which might have been transacted at the original 
meeting.

          Section 2.6  At any meeting of the stockholders, every stockholder 
entitled to vote may vote in person or by proxy authorized by an instrument in 
writing executed by such

stockholder and submitted to the Secretary at or before such meeting, but no 
proxy shall be voted or acted upon after 3 years from its date, unless the proxy
provides for a longer period. Each stockholder shall have 1 vote for each share 
of stock entitled to vote which is registered in his name on the record date for
the meeting, except as otherwise provided herein or required by law. All 
elections of directors by the stockholders shall be by written ballot, and shall
be determined by a plurality of the votes cast. All other voting need not be by 
written ballot, except upon demand therefor by the Board of Directors or the 
officer of the Corporation presiding at the meeting of stockholders where the 
vote is to be taken. When a quorum exists at any meeting, the vote of a majority
of the stock having voting power present in person or represented by proxy shall
decide any question bought before such meeting, unless the question is one for
which, by express provision of law or of the Certificate of Incorporation of the
Corporation or of these Bylaws, a different vote is required.

          Section 2.7  At least 10 days before every meeting of stockholders, 
the officer who has charge of the stock ledger of the Corporation shall prepare 
a complete list of the stockholders entitled to vote at such meeting, arranged 
in alphabetical order, and showing the address of each stockholder and the 
number of shares registered in the name of each stockholder. Such list shall be 
open to the examination of any stockholder, for any purpose germane to the 
meeting, during ordinary business hours

                                      -4-

for a period of at least 10 days prior to the meeting, either at a place within
the city where the meeting is to be held, which place shall be specified in the
notice of the meeting, or, if not so specified, at the place where the meeting
is to be held. The list shall also be produced and kept at the time and place of
the meeting during the whole time thereof, and may be inspected by any
stockholder of the Corporation who is present. The stock ledger of the
Corporation shall be the only evidence as to the identities of the stockholders
entitled to examine the list of stockholders required by this Section 2.7 or to
vote in person or by proxy at any meeting of stockholders.

     Section 2.8 The Board of Directors may appoint either one or three Judges
of Election to act at any meeting of the stockholders or any adjournment
thereof. Judges of Election need not be stockholders, and no person who is a
candidate for corporate office shall act as Judge of Election. If three Judges
of Election are appointed, such Judges of Election shall act by majority vote.
Judges of Election shall do all acts as are necessary and proper to conduct the
election or vote and all such other acts as may be prescribed by law with
fairness to all stockholders. If requested to do so by the Board of Directors or
the chairman of the meeting at which Judges of Election act, such Judges of
Election shall make a written report of any matter determined by them and shall
execute a certificate as to any fact found by them.

     Section 2.9  The chairman of any meeting of the stockholders shall 
determine the order of business and the procedure to be followed at such 
meeting, including such regulation of the manner of voting and the conduct of 
discussion as he shall deem to be fair and equitable.

     Section 2.10  The stockholders may participate in any meeting by means of 
conference telephone or similar communications equipment by means of which all 
persons participating in the meeting can hear each other, and such participation
shall constitute presence in person at such meeting.

     Section 2.11  Unless otherwise required by the Certificate of Incorporation
of the Corporation, any action required or permitted to be taken at any meeting 
of the stockholders may be taken without a meeting, without prior notice and 
without a vote, if a written consent setting forth the action so taken shall be 
signed by the holders of outstanding stock having not less than the minimum 
number of votes that would be necessary to authorize or take such action at a 
meeting at which all shares entitled to vote thereon were present and voted. 
Prompt notice of the taking of any corporate action without a meeting by less 
than unanimous written consent shall be given in conformity herewith to those 
stockholders who have not consented thereto in writing.

expressly conferred upon the Board of Directors by these Bylaws, the Board of
Directors may exercise all powers of the Corporation and perform all lawful acts
as are not required to be exercised or performed by the stockholders pursuant to
law, the Certificate of Incorporation of the Corporation or these Bylaws.

     Section 3.2 Directors shall be natural persons who need not be stockholders
of the Corporation. The specific number of directors shall be designated from 
time to time exclusively by the Board of Directors. In the absence of any such 
designation, the Board of Directors shall be composed of not less than one and 
not more than five directors. Each director shall be elected for a term of one 
year and until his successor is duly elected and qualified, subject, however, to
such director's prior death, resignation, retirement, disqualification or
removal from office. Whenever the authorized number of directors is increased
between annual meetings of the stockholders, a majority of the directors then in
office shall have the power to elect such new directors who shall serve until
the next annual meeting of stockholders and until their successors are duly
elected and qualified. Any decrease in the authorized number of directors shall
not become effective until the expiration of the term of the directors then in
office unless, at the time of such decrease, there shall be

                                      -7-
<PAGE>
 
vacancies on the Board of Directors which are being eliminated by such decrease.

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

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

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

the President or the Secretary on the written request of a majority of the 
directors then in office, and shall be held at such place, on such date and at 
such time as they or he shall designate. Notice of the place, time and date of 
each such special meeting shall be given to each director by whom it is not 
waived by mailing written notice to each director not less than 2 days before 
the meeting or by telegram or telephone not

                                      -8-
<PAGE>
 
less than 48 hours before the meeting. Notice of special meetings of the Board
of Directors need not state the purpose thereof, except as otherwise expressly
provided by law, by the Certificate of Incorporation of the Corporation, or by
these Bylaws. Any and all business may be transacted at a special meeting,
unless otherwise indicated in the notice thereof or provided by law, by the
Certificate of Incorporation of the Corporation or by these Bylaws.

     Section 3.7 Members of the Board of Directors or any committee thereof may
participate in any meeting of such Board or committee by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and such participation shall
constitute presence in person at such meeting.

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

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

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

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

committees and any others provided for herein, elect a director or directors to
serve as a member or members and designate, if it desires, one or more directors
as alternate members who may replace any absent or disqualified member at any
meeting of the committee. Any committee so designated may exercise the power and
authority of the Board of Directors to declare a dividend or to authorize the
issuance of stock if the resolution which designates the committee or a
supplemental resolution of the Board of Directors shall so provide. In the
absence or disqualification of any member of any committee and any alternate
member in his place, the member or members of the committee present at any
meeting and not disqualified from voting, whether or not he or they constitute a
quorum, may unanimously appoint another member of the Board of Directors to act
at the meeting in the place of any such absent or disqualified member. The Board
of Directors may, from time to time, suspend, alter, continue or terminate any
committee or the powers and functions thereof.

appointment of, committees consisting of officers or other persons, with 
chairmanships, vice-chairmanships and secretaryships and such duties and powers

and conducting its business and shall act in accordance therewith, except as
otherwise provided by law, by the Certificate of Incorporation of the
Corporation or by these Bylaws. Adequate provision shall be made for notice to
all members of any committee of all meetings of that committee.

                                     -13-

<PAGE>
 
duly elected and qualified or until his earlier death, resignation, retirement

                                     ---------------

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

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

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

                                     -17-
<PAGE>
 
the circumstances because he has met the applicable standard of conduct set 
forth in Section 6.1 or Section 6.2 of this Article 6, as the case may be. Such 
determination shall be made (i) by the Board of Directors by a majority vote of 
a quorum consisting of directors who are not parties to such action, suit or 
proceeding, (ii) if such a quorum is not attainable, or, even if attainable, if 
a majority vote of a quorum of disinterested directors so directs, by 
independent legal counsel in a written opinion or (iii) by the stockholders. To 
the extent, however, that a director, officer or employee of the Corporation has
been successful on the merits or otherwise in defense of any action, suit or 
proceeding described above, or in defense of any claim, issue or matter therein,
he shall be indemnified against expenses (including attorneys' fees) actually 
and reasonably incurred by him in connection therewith, without the necessity of
authorization in the specific case.

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

                                     -18-
<PAGE>
 
professionally or expertly competent to prepare such records or books of 
account), or on information supplied to him by the officers of the Corporation
or another enterprise in the course of their duties, or on the advice of legal
counsel for the Corporation or another enterprise or on information or records
given or reports made to the Corporation or another enterprise by an independent
certified public accountant or by an appraiser or other expert selected with
reasonable care by the Corporation or another enterprise. The term "another
enterprise" as used in this Section 6.4 shall mean any other corporation or any
partnership, joint venture, trust or other entity of which such person is or was
serving at the request of the Corporation as a director, officer or employee.
The provisions of this Section 6.4 shall not be deemed to be exclusive or to
limit in any way the circumstances in which a person may be deemed to have met
the applicable standard of conduct set forth in Section 6.1 or 6.2 of this
Article 6, as the case may be.

     Section 6.5  Notwithstanding any contrary determination in the specific
case under Section 6.3 of this Article 6, and notwithstanding the absence of any
determination thereunder, any director, officer or employee may apply to any
court of competent jurisdiction in the state of Delaware for indemnification to
the extent otherwise permissible under Sections 6.1 and 6.2 of this Article 6.
The basis of such indemnification by a court shall be a determination by such
court that indemnification of the director, officer or employee is proper in the
circumstances

                                     -19-
<PAGE>
 
because he has met the applicable standards of conduct set forth in Section 6.1 
or 6.2 of this Article 6, as the case may be. Notice of any application for 
indemnification pursuant to this Section 6.5 shall be given to the Corporation 
promptly upon filing of such application.

     Section 6.6 Expenses incurred in defending or investigating a threatened or
pending action, suit or proceeding may be paid by the Corporation in advance of 
the final disposition of such action, suit or proceeding as authorized by the 
Board of Directors upon receipt of an undertaking by or on behalf of the 
director, officer or employee to repay such amount if it shall ultimately be 
determined that he is not entitled to be indemnified by the Corporation as 
authorized in this Article 6.

     Section 6.7 The indemnification and advancement of expenses provided by, or
granted pursuant to, the other sections of this Article 6 shall not be deemed 
exclusive of any other rights to which those seeking indemnification or 
advancement of expenses may be entitled under any by-law, agreement, contract, 
vote of stockholders or disinterested directors or pursuant to the direction 
(howsoever embodied) of any court of competent jurisdiction or otherwise, both 
as to action in his official capacity and as to action in another capacity while
holding such office, it being the policy of the Corporation that indemnification
of, and advancement of expenses to, the persons specified in Section 6.1 and 6.2
of this Article 6 shall be made

                                     -20-
<PAGE>
 
to the fullest extent permitted by law. To this end, the provisions of this 
Article 6 shall be deemed to have been amended for the benefit of such persons 
effective immediately upon any modification of the General Corporation Law of 
the State of Delaware which expands or enlarges the power or obligation of 
corporations organized under such law to indemnify, or advance expenses to, such
persons. The provisions of this Article 6 shall not be deemed to preclude the 
indemnification of, or advancement of expenses to, any person who is not 
specified in Section 6.1 or 6.2 of this Article 6 but whom the Corporation has 
the power or obligation to indemnify, or to advance expenses for, under the 
provisions of the General Corporation Law of the State of Delaware or otherwise.
The indemnification and advancement of expenses provided by, or granted pursuant
to, this Article 6 shall, unless otherwise provided when authorized or ratified,
continue as to a person who has ceased to be a director, officer or employee and
shall inure to the benefit of the heirs, executors and administrators of such 
person.

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

                                     -21-


<PAGE>
 
power or the obligation to indemnify him against such liability under the 
provisions of this Article 6.

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

other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not be more than 60 nor less than 10 days before the date of such
meeting nor more than 60 days prior to any other action. A determination of

laws of the State of Delaware.

     Section 7.5  The Board of Directors may authorize the issuance of a new

the Certificate of Incorporation of the Corporation or these Bylaws, a written 
waiver thereof, signed by the person entitled to notice, whether before or after
the time stated therein, shall be deemed equivalent to notice. Attendance of a 
person at a meeting shall constitute a waiver of notice of such meeting, except 
as otherwise provided by law. Neither the business to be transacted at, nor the 
purpose of, any regular or special meeting of the stockholders, directors, or 
members of a committee of directors need be specified in any written waiver of

Delaware a registered office which may, but need not be, the same as its place
of business.

     SECTION 1.2   The Corporation may also have offices at such other places as

Corporation may require.

                            ARTICLE 2  STOCKHOLDERS

     SECTION 2.1   All meetings of the stockholders shall be held at such place,
either within or without the State of Delaware, and at such date and time as may

of the meeting or in a duly executed waiver of notice thereof.

     SECTION 2.2   An annual meeting of the stockholders, for the election of
directors and for the transaction of such other business as may properly be
brought before the meeting, shall be held at such place, date and time as the

May each year on a date to be determined from year to year by the Board of
Directors.

     SECTION 2.3   Special meetings of the stockholders, for any purpose or
purposes, may be called by the Board of Directors or the President and shall be
called by the President or the Secretary at the request in writing of a majority

all special meetings shall be confined to the objects stated in the notice
thereof.

     SECTION 2.4   Written notice of any annual or special meeting of
stockholders shall be mailed to each stockholder entitled to vote thereat at his
address as it appears on the records of the Corporation, not fewer than ten nor

meeting, present in person or by proxy, shall constitute a quorum for all
purposes, except to the extent that the presence of a larger number of
stockholders may be required by law, by the Certificate of Incorporation of the
Corporation or by these By-laws.  If a quorum shall fail to be present or

permitted by law, and submitted to the Secretary at or before such meeting, but
no proxy shall be voted or acted upon after three years from its date, unless
the proxy provides for a longer period. Each stockholder shall have one vote
for each share of stock entitled to vote that is registered in his name on the
record date for the meeting, except as otherwise provided herein or required by
law. All elections of directors by the stockholders shall be by written ballot
and shall be determined by a plurality of the votes cast. All other voting need
not be by written ballot, except upon demand therefor by the Board of Directors
or the officer of the Corporation presiding at the meeting of stockholders where
the vote is to be taken. When a quorum exists at any meeting, the vote of a
majority of the stock having voting power present in person or represented by
proxy shall decide any 

                                      -3-
<PAGE>
 
question brought before such meeting, unless the question is one for which, by
express provision of law or of the Certificate of Incorporation of the
Corporation or of these By-laws, a different vote is required.

     SECTION 2.7   At least ten days before every meeting of stockholders, the
officer who has charge of the stock ledger of the Corporation shall prepare a
complete list of the stockholders entitled to vote at such meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  Such list shall be open
to the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours for a period of at least ten days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held.  The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof and may be inspected by any stockholder of the Corporation who is
present.  The stock ledger of the Corporation shall be the only evidence as to
the identities of the stockholders entitled to examine the list of stockholders
required by this Section 2.7 or to vote in person or by proxy at any meeting of
stockholders.

     SECTION 2.8   The Board of Directors shall appoint either one or three
inspectors of election, in advance of any meeting of stockholders, to act at
such meeting of the stockholders or any adjournment thereof. Inspectors of
election need not be stockholders, and no person who is a candidate for

election are appointed, such inspectors of election shall act by majority vote.
Each inspector of election shall sign an oath faithfully to 

                                      -4-

execute the duties of inspector with strict impartiality and to the best of the
inspector's ability and shall do all acts as are necessary and proper to
conduct the election or vote and all such other acts as may be prescribed by law
with fairness to all stockholders. Such inspectors of election shall make a
written report of any matter determined by them and shall execute a certificate

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

     SECTION 2.10  The stockholders may participate in any meeting by means of
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear one another, and such
participation shall constitute presence in person at such meeting.

     SECTION 2.11  Unless otherwise required by the Certificate of
Incorporation of the Corporation, any action required or permitted to be taken
at any meeting of the stockholders may be taken without a meeting, without prior
notice and without a vote, if a written consent setting forth the action so
taken shall be signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted.  Prompt notice of the taking of any corporate action without a
meeting by less than unanimous written consent shall be given in conformity
herewith to those stockholders who have not consented thereto in writing.

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

     SECTION 3.2   Directors shall be natural persons who need not be
stockholders of the Corporation. The specific number of directors shall be
designated from time to time exclusively by the Board of Directors. In the
absence of any such designation, the Board of Directors shall be composed of one
director. Each director shall be elected for a term of one year and until his
successor is duly elected and qualified, subject, however, to such director's
prior death, resignation, retirement, disqualifica tion or removal from office.
Whenever the authorized number of directors is increased between annual meetings
of the stockholders, a majority of the directors then in office shall have the
power to elect such new directors who shall serve until the next annual meeting
of stockholders and until their successors are duly elected and qualified. Any
decrease in the authorized number of directors shall not become effective until
the expiration of the term of the directors then in office unless, at the time
of such decrease, there shall be vacancies on the Board of Directors that are
being eliminated by such decrease.

     SECTION 3.3   Any vacancy on the Board of Directors occurring by reason of
death, resignation, disqualification, removal or other cause may be filled by a
majority 

                                      -6-
<PAGE>
 
of the directors then in office, although less than a quorum, and each director
elected to fill a vacancy shall serve for the unexpired term of his predecessor
and until his successor is duly elected and qualified.

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

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

     SECTION 3.6   Special meetings of the Board of Directors may be called by
the Chairman of the Board, by the President or by the Secretary upon his own
initiative or upon the written request of a majority of directors then in
office. Notice of the place, time and date of each such special meeting shall be
given to each director by whom it is not waived by mailing written notice to
each director not less than two days before the meeting or by giving notice in
person or by telephone, telegram or facsimile transmission not less than twenty-
four hours before the meeting. Notice of special meetings of the Board of
Directors need not state the purpose thereof, except as otherwise expressly
provided by law, by the Certificate of Incorporation of the Corporation, or by
these By-laws. Any and all business may be transacted at a special meeting,
unless otherwise indicated in the notice thereof or provided by law, by the
Certificate of Incorporation of the Corporation or by these By-laws.

     SECTION 3.7   Members of the Board of Directors or any committee thereof
may

                                      -7-
<PAGE>
 
participate in any meeting of the Board of Directors or such committee, as the
case may be, by means of conference telephone or similar communications
equipment by means of which all persons participating in the meeting can hear
one another, and such participation shall constitute presence in person at such
meeting.

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

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

     SECTION 3.10  Directors, in addition to expenses of attendance, shall be
allowed such compensation for their services as directors, including, without
limitation, their services as members of committees of the Board of Directors,
as may be fixed from time to time by the Board of Directors; provided, that
nothing contained in these By-

                                      -8-
<PAGE>
 
laws shall be construed to preclude any director from serving the Corporation in
any other capacity and receiving compensation therefor.

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

     SECTION 4.1   The Board of Directors, by a vote of a majority of the whole
Board of Directors, may from time to time designate committees of the Board of
Directors, with such lawfully delegable powers and duties as it thereby confers,
to serve at the pleasure of the Board of Directors and shall, for those
committees and any others provided for herein, elect a director or directors to
serve as a member or members and designate, if it desires, one or more directors
as alternate members who may replace any absent or disqualified member at any
meeting of the committee.  Any committee so designated may exercise the power
and authority of the Board of Directors to declare a dividend or to authorize
the issuance of stock if the resolution that designates the committee or a
supplemental resolution of the Board of Directors shall so provide.  In the
absence or disqualification of any member of any committee and any alternate
member in his place, the member or members of the committee present at any
meeting and not disqualified from voting, whether or not he or they 

                                      -9-

constitute a quorum, may unanimously appoint another member of the Board of
Directors to act at the meeting in the place of any such absent or disqualified
member. The Board of Directors may, from time to time, suspend, alter, continue
or terminate any committee or the powers and functions thereof.

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

     SECTION 4.3   One-third of the members of any committee shall constitute a
quorum unless the committee shall consist of one or two members, in which case
one member shall constitute a quorum.  All matters properly brought before any
committee shall be determined by a majority vote of the members present.

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

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

powers or duties of any officer to any other officers or agents, notwithstanding
any provision of these By-laws.

     SECTION 5.5   The Chairman of the Board shall be a director of the 
Corporation. The Chairman of the Board shall preside at all meetings of the

from time to time be assigned to him by the Board of Directors.

     SECTION 5.7   Each Vice President shall have such powers and perform such

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

                                      -12-

perform the preceding duties for any committee of the Board of Directors upon
the request of the Board of Directors or such committee. The Secretary shall

                          ARTICLE 6  INDEMNIFICATION

     SECTION 6.1   Subject to Section 6.3 hereof, the Corporation shall
indemnify any person who was or is a party or has threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, 

                                      -13-
<PAGE>
 
administrative or investigative (other than an action by or in the right of the
Corporation) by reason of the fact that he is or was a director, officer or
employee of the Corporation, or is or was serving at the request of the
Corporation as a director, officer or employee of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in, or not opposed to, the best interests of the Corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
his conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner that he reasonably believed to be in, or
not opposed to, the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had reason able cause to believe that his conduct
was unlawful.

     SECTION 6.2   Subject to Section 6.3 hereof, the Corporation shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of
the Corporation to procure a judgment in its favor by reason of the fact that he
is or was a director, officer or employee of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, or employee of
another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection with the defense or settlement   

                                      -14-
<PAGE>
 
of such action or suit if he acted in good faith and in a manner he reasonably
believed to be in, or not opposed to, the best interests of the Corporation;
except that no indemnification shall be made in respect of any claim, issue or
matter as to which such person shall have been adjudged to be liable to the
Corporation unless and only to the extent that the Court of Chancery or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

     SECTION 6.3   Any indemnification under this Article 6 (unless ordered by a
court) shall be made by the Corporation only as authorized in the specific case
upon a determination that indemnification of the director, officer or employee
is proper in the circumstances because he has met the applicable standard of
conduct set forth in Section 6.1 or Section 6.2 of this Article 6, as the case
may be.  Such determination shall be made (i) by the Board of Directors by a
majority vote of a quorum consisting of directors who are not parties to such
action, suit or proceeding, (ii) if such a quorum is not attainable, or, even if
attainable, if a majority vote of a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion or (iii) by the
stockholders.  To the extent, however, that a director, officer or employee of
the Corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding described above, or in defense of any claim, issue or
matter therein, he shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection therewith, without
the necessity of authori-  

                                      -15-
<PAGE>
 
zation in the specific case.

     SECTION 6.4   For purposes of any determination under Section 6.3 of this
Article 6, a person shall be deemed to have acted in good faith and in a manner
he reasonably believed to be in, or not opposed to, the best interests of the
Corporation, or, with respect to any criminal action or proceeding, to have had
no reasonable cause to believe his conduct was unlawful, if his action is based
on the records or books of account of the Corporation or another enterprise
(provided that such records or books of account have in each case been prepared
by persons whom the person relying thereon reasonably believes to be
professionally or expertly competent to prepare such records or books of
account), or on information supplied to him by the officers of the Corporation
or another enterprise in the course of their duties, or on the advice of legal
counsel for the Corporation or another enterprise or on information or records
given or reports made to the Corporation or another enterprise by an independent
certified public accountant or by an appraiser or other expert selected with
reasonable care by the Corporation or another enterprise.  The term "another
enterprise" as used in this Section 6.4 shall mean any other corporation or any
partnership, joint venture, trust or other entity of which such person is or was
serving at the request of the Corporation as a director, officer or employee.
The provisions of this Section 6.4 shall not be deemed to be exclusive or to
limit in any way the circumstances in which a person may be deemed to have met
the applicable standard of conduct set forth in Section 6.1 or 6.2 of this
Article 6, as the case may be.

     SECTION 6.5   Notwithstanding any contrary determination in the specific
case under Section 6.3 of this Article 6, and notwithstanding the absence of any
determina- 

                                      -16-
<PAGE>
 
tion thereunder, any director, officer or employee may apply to any court of
competent jurisdiction in the State of Delaware for indemnification to the
extent otherwise permissible under Sections 6.1 and 6.2 of this Article 6. The
basis of such indemnification by a court shall be a determination by such court
that indemnification of the director, officer or employee is proper in the
circumstances because he has met the applicable standards of conduct set forth
in Section 6.1 or 6.2 of this Article 6, as the case may be. Notice of any
application for indemnification pursuant to this Section 6.5 shall be given to
the Corporation promptly upon the filing of such application.

     SECTION 6.6   Expenses incurred in defending or investigating a threatened
or pending action, suit or proceeding may be paid by the Corporation in advance
of the final disposition of such action, suit or proceeding as authorized by the
Board of Directors upon receipt of an undertaking by or on behalf of the
director, officer or employee to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by the Corporation as
authorized in this Article 6.

     SECTION 6.7   The indemnification and advancement of expenses provided by,
or granted pursuant to, the other sections of this Article 6 shall not be deemed
exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any by-law, agreement, contract,
vote of stockholders or disinterested directors or pursuant to the direction
(howsoever embodied) of any court of competent jurisdiction or otherwise, both
as to action in his official capacity and as to action in another capacity while
holding such office, it being the policy of the Corporation that indemnification
of, and advancement of expenses to, the persons specified in Sections 6.1 and
6.2 of this Article 6 shall be made to the fullest 

                                      -17-
<PAGE>
 
extent permitted by law. To this end, the provisions of this Article 6 shall be
deemed to have been amended for the benefit of such persons effective
immediately upon any modification of the General Corporation Law of the State of
Delaware which expands or enlarges the power or obligation of corporations
organized under such law to indemnify, or advance expenses to, such persons. The
provisions of this Article 6 shall not be deemed to preclude the indemnification
of, or advancement of expenses to, any person who is not specified in Section
6.1 or 6.2 of this Article 6 but whom the Corporation has the power or
obligation to indemnify, or to advance expenses for, under the provisions of the
General Corporation Law of the State of Delaware or otherwise. The
indemnification and advancement of expenses provided by, or granted pursuant to,
this Article 6 shall, unless otherwise provided when authorized or ratified,
continue as to a person who has ceased to be a director, officer or employee and
shall inure to the benefit of the heirs, executors and administrators of such
person.

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

     SECTION 6.9   For purposes of this Article 6, references to the
"Corporation" 

                                      -18-
<PAGE>
 
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had the power and authority to indemnify its directors, officers and
employees, so that any person who is or was a director, officer or employee of
such constituent corporation, or is or was serving at the request of such
constituent corporation as a director, officer or employee of another
corporation, partnership, joint venture, trust or other enterprise, shall stand
in the same position under the provisions of this Article 6 with respect to the
resulting or surviving corporation as he would have with respect to such
constituent corporation if its separate existence had continued.


                               ARTICLE 7  STOCK

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

                                      -19-
<PAGE>
 
     SECTION 7.2   Transfers of stock shall be made only upon the transfer books
of the Corporation maintained in an office of the Corporation or by transfer
agents designated to transfer shares of the stock of the Corporation, and only
by the person named in the certificate or by his attorney, lawfully constituted
in writing, and upon surrender of the certificate therefor.

     SECTION 7.3   In order that the Corporation may determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not be more than sixty nor less than ten days before the date of
such meeting nor more than sixty days prior to any other action.  A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting; provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

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

     SECTION 7.5   The Board of Directors may authorize the issuance of a new

                                      -20-
<PAGE>
 
certificate representing shares of stock in place of any certificate previously
issued by the Corporation and alleged to have been lost, stolen or destroyed,
pursuant to such regulations as the Board of Directors may establish concerning
proof or advertisement of such alleged loss, theft or destruction and concerning
the giving of a satisfactory bond or bonds sufficient to indemnify the
Corporation against any claim that may be made against it on account of the
alleged loss, theft or destruction of any such certificate.

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


                              ARTICLE 8  NOTICES

     SECTION 8.1   Whenever notice is required to be given to any director,
committee member, officer, stockholder, employee or agent, whether pursuant to
law, the Certificate of Incorporation of the Corporation or these By-laws, it
shall not be construed to mean personal notice, but such notice may be given, in
the case of stockholders, in writing, by depositing the same in the mail,
postage prepaid, or by overnight carrier addressed to such stockholder at his
last known address as the same appears on the books of the Corporation, and, in
the case of directors, committee members, officers, employees and agents, by
telephone, or by mail, postage prepaid, or by prepaid telegram at his last known
address as the same appears on the books of the Corporation. All notices shall
be deemed to be given when mailed, telegraphed or telephoned.

<PAGE>
 
     SECTION 8.2   Whenever notice is required to be given to any stockholder,
director, committee member, officer, employee or agent, whether pursuant to law,
the Certificate of Incorporation of the Corporation or these By-laws, a written
waiver thereof, signed by the person entitled to notice, whether before or after
the time stated therein, shall be deemed equivalent to notice.  Attendance of a
person at a meeting shall constitute a waiver of notice of such meeting, except
as otherwise provided by law.  Neither the business to be transacted at, nor the
purpose of, any regular or special meeting of the stockholders, directors, or
members of a committee of directors need be specified in any written waiver of
notice unless so required by the Certificate of Incorporation of the Corporation
or by these By-laws.

                           ARTICLE 9  MISCELLANEOUS

     SECTION 9.1   Any officer of the Corporation shall, if required by the
Board of Directors, give the Corporation a bond for the faithful performance of
the duties of his office, and for the restoration to the Corporation of all
corporate books, papers, vouchers, money and property of whatever kind in his
possession or under his control. Such bond shall be for a sum and with such
surety or sureties as the Board of Directors may require.

     SECTION 9.2   The corporate seal shall be in the charge of the Secretary
and shall have inscribed thereon the name of the Corporation and the words
"Incorporated 1996 Delaware." If and when so directed by the Board of Directors
or a committee thereof, the Secretary may have duplicates of such seal made and
deposited for use with other officers of the Corporation. It shall not be
necessary to the validity of any 

                                      -22-
<PAGE>
 
instrument executed by any authorized officer or officers of the Corporation
that the execution of such instrument be evidenced by the corporate seal.

     SECTION 9.3   The fiscal year of the Corporation shall be as determined by
the Board of Directors.

     SECTION 9.4   All checks or demands for money and notes of the Corporation
shall be signed by such officer or officers as the Board of Directors may from
time to time designate.

     SECTION 9.5   The Board of Directors shall determine from time to time
whether, when and under what conditions and regulations, the books and records
of the Corporation (except such as may by statute be specifically open to
inspection) shall be open to the inspection of the stockholders, and the
stockholders' rights in this respect are and shall be restricted and limited
accordingly.

     SECTION 9.6   Facsimile signatures of any officer of the Corporation may be
used at such time and in such manner as authorized by the Board of Directors or
a committee thereof.


                             ARTICLE 10  AMENDMENT

majority of the Directors then in office, at any meeting of the Board of
Directors, or (b) by the affirmative vote of the stockholders at any

description of such proposed amendment, suspension or repeal and/or adoption of

otherwise changed liability, and except to the extent a Partner contributes

of any variation between the adjusted basis of such property to the Partnership
for federal income tax purposes and its initial Gross Asset Value in accordance
with Code Section 704(c) and the Regulations thereunder.

                      6.4.6.2  Other Property with Gross Asset Value Different

from Tax Basis. In the event that the Gross Asset Value of any Partnership asset

is adjusted, subsequent allocations of income, gain, loss and deduction with
respect to such asset, as computed for the purpose of determining taxable
income, shall take account of any variation between the adjusted basis of such
asset for federal income tax purposes and its Gross Asset Value in the manner
provided in Regulations Section 1.704-1(b)(4)(i).

                      6.4.6.3  Tax Elections; Effects on Capital Accounts.  Any

manner that reasonably reflects the purposes and intentions of this Agreement.
Allocations made pursuant to this Section 6.4.6 are solely for purposes of
federal, state and local taxes and shall not affect, or be taken into account in
computing, any Partner's Capital Account, share of Profits and Losses, or
distributions pursuant to any provision of this Agreement.

               6.4.7  Compliance with Code and Regulations.  The provisions of
                      ------------------------------------                    
this Agreement that relate to the allocations for federal income tax purposes of
items of Partnership income (including Exempt Income), gain, loss, deduction and
Nondeductible Expenditure (including, without limitation, the allocation of such
items with respect to property having a Gross Asset Value different from
adjusted federal income tax basis), that relate to the determination and
maintenance of Capital Accounts, and that relate to the distribution of
Partnership property upon the liquidation of the Partnership or a Partner's
interest therein, are intended to comply with Regulations Section 1.704-1(b) (to
the extent not superseded by Regulations Section 1.704-2) and Regulations
Section 1.704-2, and with Code Section 704(c) and the Regulations promulgated
thereunder and, except as otherwise provided in the definition of a "Capital
Account" as set forth in Section 1.6 hereof, shall be interpreted and applied in
a manner consistent with such statutory and regulatory provisions, which
statutory and regulatory provisions are expressly incorporated into and made a
part of this Agreement.  Should such statutory and regulatory provisions be
amended, the affected provisions of this Agreement shall be interpreted and
applied in accordance with such amended provisions.

               6.4.8  Allocation in the Event of Transfer.  If an Interest in
                      -----------------------------------                    
the Partnership is transferred in accordance with Article VIII hereof, there
shall be allocated to each Partner which held the transferred interest during
the Fiscal Year of transfer the product of (a) the Partnership's Profits and
Losses allocable to such transferred interest for such Fiscal Year, and (b) a
fraction the numerator of which is the number of days such Partner held the
transferred interest during such Fiscal Year and the denominator of which is the
total number of days in such Fiscal Year; provided however, that the transferor
and transferee may elect to allocate such Profit or Loss by closing the books of
the Partnership immediately after the transfer of an Interest.  If an allocation
is made without a closing of the books of the Partnership, the allocation shall
be made without regard to the date, amount or recipient of any such
distributions which may have been made with respect to such transferred
interest.

distributed between the Partners 55% to the General Partner and 45%to the
Limited Partner.

        7.2    Distributions of Net Proceeds of a Sale Transaction.  Except as
               ---------------------------------------------------

        7.3    Tax Payment Loans.  At the sole option of the General Partner,
               ------------------
the Partnership shall lend each year to the General Partner funds up to the
amount of money equal to the following (the "General Partner's Tax Liability"):
(i) the taxable income allocated to the General Partner for such Fiscal Year as
a result of the Profit allocation pursuant to Section 6.1 hereof multiplied by
(ii) the highest marginal effective Federal and Pennsylvania corporate income
tax rate applicable to the General Partner with respect to that Fiscal Year, as
and when the General Partner shall be obligated to make payments of estimated
tax with respect to the allocation of such Profits but in no event later than
sixty days after the close of the Fiscal Year of the Partnership with respect to
which the allocation of Profit is made. It shall be a condition to the making of
any loan under this Section 7.3 that there shall be sufficient Cash Flow (after
taking into account any loan under this Section 7.3) available for distribution
to the Limited Partner in accordance with Section 7.1 to equal the following
(the "Limited Partner's Tax Liability"): (i) the taxable income allocated to the
Limited Partner for the Fiscal Year as a result of the Profit allocation
pursuant to Section 6.1 hereof multiplied by (ii) the highest marginal statutory
Federal and Delaware corporate income tax rate with respect to that Fiscal Year
(taking into account the deductibility of the Delaware corporate income tax for
purposes of computing Federal taxable income). If there is insufficient Cash
Flow (before taking into account any loan under this Section 7.3) in any Fiscal
Year to equal the sum of the General Partner's Tax Liability and the Limited
Partner's Tax Liability, then the ratio of (i) the loan amount under this
Section 7.3 for the Fiscal Year, to (ii) the total distributions of Cash Flow to
the Limited Partner under Section 7.1 for such Fiscal Year, shall be, as nearly
as possible, the same as the ratio of (i) the General Partner's Tax Liability to
(ii) the Limited Partner's Tax Liability.

        8.1    Restrictions on Transfer.  Except as provided in Article X
               ------------------------
hereof, no Partner may, without the prior written consent (which may be
arbitrarily withheld) of the other Partner, sell, convey, transfer, syndicate,
assign, mortgage, pledge, hypothecate or otherwise encumber in any way
(hereinafter referred to as a "transfer") all or any portion of its Interest in
the Partnership or in any property of the Partnership, or withdraw or retire
from the Partnership, and any such attempted transfer, withdrawal or retirement
not permitted hereunder shall be null and void. Notwithstanding the foregoing
sentence, a Partner shall be permitted to transfer its interest to its parent
corporation or to a wholly-owned subsidiary of such Partner or its parent
corporation; provided however, that such transfer will not cause a termination
of the Partnership for Federal income tax purposes, and, with respect to a
transfer of the General Partner's interest, the consent of the Limited Partner
is received, which consent may not be unreasonably withheld.

        8.2    Survival of Restrictions on Transfer.  In the event of any
               ------------------------------------
transfer pursuant to this Article VIII, the Interest so transferred shall remain
subject to all restrictions and rights contained in this Article VIII and the
transferee shall execute and deliver written instruments, in form and substance
satisfactory to the Partners, agreeing to be bound by all provisions of this
Agreement.

a Partner shall be admitted as a Partner in the Partnership unless the assignee
expressly agrees to be bound by the provisions of this Agreement and to assume
the obligations of its assignor under this Agreement and agrees to pay all
reasonable expenses and legal fees relating to the assignment and its admission
as a Partner in the Partnership. Upon the admission of a substituted Partner,
this Agreement shall be amended to reflect the name and address of the
substituted Partner and eliminate the name and address of the assignor and an
amendment to the certificate of limited partnership of the Partnership shall be
filed, if required by the Act. A Partner who assigns all of its Interest shall
cease to be a Partner and shall no longer have any rights or privileges of a
Partner except that unless and until its assignee is admitted to the Partnership
as a substituted Partner in accordance with this Article VIII, the assignor
Partner shall retain all rights and be subject to all obligations under this
Partnership Agreement and the Act.

have been distributed as provided in this Agreement.  Notwithstanding the
dissolution of the Partnership prior to the termination of the Partnership, as
aforesaid, the business of the Partnership and the affairs of the Partners as
such shall continue to be governed by this Agreement.

               9.1.2   Notwithstanding anything in this Agreement to the
contrary, upon a sale of all or substantially all of the assets of the
Partnership where all or any portion of the consideration payable to the
Partnership is to be received by the Partnership more than ninety (90) days
after the date on which such sale occurs, the Partnership shall continue solely
for purposes of collecting the deferred payments and making distributions to the
Partners. In such event (i) Profits and Losses recognized and Net Proceeds of a
Sale or Refinance Transaction distributed in any year as a result of such sale
shall be allocated and distributed among the Partners in the same proportion as
such Profits and Losses and Net Proceeds of a Sale or Refinance Transaction
would have been allocated and distributed were the entire gain resulting from
such sale required to be recognized for Federal income tax purposes in the year
in which such sale occurred; and (ii) income attributable to interest on any
deferred payments shall be allocated between, and such interest shall be
distributed to, the Partners as if the deferred payment obligations received by
the Partnership had been distributed in-kind to the Partners under Section 9.2
hereof in the proportions provided for in Section 7.2 hereof.

                     9.2.1.1  Any reserves shall be established or continued
which the General Partner deems reasonably necessary for any contingent or
unforeseen liabilities or obligations of the Partnership. Such reserves shall be
held by the Partnership for the payment of any of the aforementioned
contingencies, and at the expiration of such period as the General Partner shall
deem advisable, the Partnership shall distribute the balance thereafter
remaining to the Partners in accordance with Section 7.2 hereof.

              9.2.2  Upon dissolution and liquidation of the Partnership, each

Partner, it shall have no recourse or further right or claim against the

the employment of Executive by Employer and for certain other matters in
connection with such employment, all as set forth more fully in this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein, the parties hereto, intending to be legally bound,
agree as follows:

         1.   Employment.
              ---------- 
<PAGE>
 
          Employer hereby employs Executive and Executive hereby accepts
employment as President, Chief Executive Officer and Chairman of the Board of
Directors ("Board") of Employer in accordance with the terms and conditions
hereinafter set forth.

     2.   Term.
          ---- 

          The term of this Agreement shall be five (5) years commencing on the
date hereof ("Initial Term"), unless earlier terminated pursuant to Paragraph 7
below; provided, however, that unless earlier terminated pursuant to Paragraph 7
below, the Initial Term of this Agreement shall thereafter be renewed from year
to year (each, a "Renewal Term") unless either party gives written notice of
termination to the other at least one hundred eighty (180) days prior to the
expiration of such Initial Term or Renewal Term, as the case may be.  The
Initial Term and any Renewal Term(s) are hereinafter referred to, collectively,
as the "Term."

     3.   Duties.
          ------ 

          Executive is engaged hereunder as President, Chief Executive Officer
and Chairman of the Board of Employer and agrees to perform such duties and
services as are customarily incident to such offices and such other duties and
services as may be assigned to him from time to time by the Board; provided,
however, that it is expressly understood that Executive will not be required to
relocate in order to perform his duties hereunder.  During his employment
hereunder, Executive shall conduct himself at all times so as to advance the
best interests of Employer and shall not undertake or engage in any other
business activity which interferes with the performance of his duties hereunder
without the prior written consent of Employer.  It is expressly understood that
nothing in this Agreement shall preclude Executive from owning not more than
five percent (5%) of the issued and outstanding shares of a class of securities
of a

                                      A-2

corporation the securities of which are traded on a national security exchange
or in the over-the-counter market.

     4.   Compensation.
          ------------ 

          For all services rendered by Executive under this Agreement, Employer
shall pay Executive a base salary of not less than Three Hundred Sixty Thousand
Dollars ($360,000) per annum, payable in equal semi-monthly installments,
together with such additional compensation, including bonus, if any, as the
Board may determine from time to time in its sole discretion (the "Salary").
The Salary shall be reviewed on or about August 1st of each year and may be
increased in the sole discretion of the Board based on corporate policy and
Executive's performance.

     5.   Expenses.
          -------- 

          Executive is authorized to incur reasonable expenses for promoting
Employer's business, including expenses for entertainment, travel, and similar
items.  Employer will reimburse Executive for all such expenses provided such
expenses have been included in an operating plan for Employer which has been
approved by the unanimous consent of the Employer's Board ("Approved Operating
Plan") and provided further Executive shall have presented to Employer
appropriate vouchers itemizing such expenses in a form consistent with
Employer's policy.  Notwithstanding the foregoing, Employer shall pay directly
all expenses, including but not limited to rent, staff salaries, utilities and
other reasonable expenses, incurred in the maintenance of Executive's main
office located in Northeastern Pennsylvania, provided such expenses have been
included in an Approved Operating Plan.

officers.  Executive shall be included in any profit-sharing, pension,
retirement or other employee benefit plan of Employer that may include as
beneficiaries executive officers of Employer, whether now in force or
subsequently implemented by Employer.

      7.   Termination of Employment.   This Agreement may not be terminated
           -------------------------                                        
during the Term, other than as provided below:

          (a) Death of Executive.  In the event of the death of Executive during
              ------------------                                                
the Term, this Agreement shall terminate and Employer shall have no further
obligation or liability hereunder except to pay to Executive's executor or
administrator, within sixty (60) days after the date of death, the portion, if
any, of Executive's Salary for the period through the date of Executive's death,
unless previously paid.

diagnosis of a physician engaged by Employer for that purpose, renders Executive
unable or incompetent to perform his duties hereunder ("Total Disability"),
which condition continues for a period of ninety (90) consecutive days during
the Term of this Agreement, Employer shall have the right to terminate
Executive's employment hereunder by giving Executive ten (10) days' written
notice thereof and, upon expiration of such ten-day period, Employer shall have
no further obligation or

                                      A-4

          (c) Resignation.  Executive may voluntarily terminate his employment
              -----------                                                     
under this Agreement by giving Employer no less than one hundred eighty (180)
days written notice of his intention to do so including the date upon which such
termination shall become effective, which date shall not be sooner than one
hundred eighty (180) days from the date on which such notice is given.
Following the effective date of such resignation, Executive shall have no
further obligation or liability under this Agreement and Employer shall have no
further obligation or liability under this Agreement except to pay to Executive
the same amounts which are payable under Paragraph 7(a).

          (d) Termination for Cause.  The Employer may terminate this Agreement
              ---------------------                                            
at any time for Cause (as hereinafter defined) upon written notice to Executive,
effective upon the date of such written notice.  "Cause" shall be defined as (a)
conviction of the Executive for a felony or misdemeanor involving dishonesty,
fraud or moral turpitude under the laws of the United States or any state
thereof or other jurisdiction in which Executive performs services; (b) breach
of Section 9 hereof; or (c) removal of WinCup as General Partner of Employer
pursuant to Section 8.4 of that certain Limited Partnership Agreement, dated as
of the date hereof, between WinCup and James River.  In the event of termination
for Cause, the Employer shall have no further obligations or liabilities to
Executive hereunder, except that Executive shall be entitled to receive any
accrued but unpaid Salary and expense reimbursement, and to retain all other
amounts received by Executive pursuant to this Agreement prior to such
termination for Cause.

      8.  Non-Disclosure of Trade Secrets and Other Information.
          ----------------------------------------------------- 

          Executive agrees that he will not, during the Term of this Agreement
or at any time thereafter, use for himself or divulge to others any secret or
confidential information, knowledge, or data of Employer, developed by him or
obtained by him as a result of his employment, unless authorized by Employer in
writing.  It is understood that this applies to information of either a
technical or commercial nature, including secret processes, formulas, machinery,
utensils, manufacturing techniques and arts, customer lists, market information
and the like.  The terms 'secret' and 'confidential' shall include all
unpublished information and all information and data known to some but not to
all members of the trade or industry to whom such information or data would be
in any manner useful.

          All memoranda, notes, records, or other documents made or compiled by
Executive, or made available to Executive while employed by Employer, are
Employer's property and all copies thereof shall be delivered to Employer on
termination of Executive's employment or at any other time upon the request of
Employer.

      9.   Restrictive Covenant.
           -------------------- 

           (a)  Non-Competition.
                --------------- 

                Executive agrees that, so long as he is employed by Employer
pursuant to this Agreement and for a period of five (5) years thereafter, he
will not, directly or indirectly, as a sole proprietor, member of a partnership,
stockholder, investor, officer or director of a corporation, or as an employee,
agent, associate or consultant of any person, partnership or corporation other
than Employer or in any other capacity:

                (i)   own, manage, operate, participate in, perform services for
or otherwise carry on a business which sells or manufactures one-piece foam cups
within the

                                      A-6
<PAGE>
 
United States or Canada (the "Territory"); provided that ownership of not more
than five percent (5%) of the issued and outstanding shares of a class of
securities of a corporation the securities of which are traded on a national
security exchange or in the over-the-counter market shall not be deemed
ownership of the issuer of such shares for the purposes of this section;

              (ii)  induce or attempt to persuade any employee of Employer or
any of its affiliates to terminate such employment relationship in order to
enter into any such relationship with such person or to enter into any such
relationship on behalf of any other business organization which sells or
manufactures one-piece foam cups in the Territory;

              (iii) solicit any business related to the manufacture or sale of
one-piece foam cups in the Territory from any clients, customers, or prospective
or former clients or customers of Employer or its affiliates; or

              (iv)  perform services of any nature for any entity which
manufactures or sells one-piece foam cups in the Territory.

          (b) Injunctive Relief.  Without limiting the right of Employer or any
              -----------------                                                
of its successors or permitted assigns to pursue all other legal and equitable
rights available to them for violation of the covenants set forth in
subparagraph 9(a) hereof, it is agreed that such other remedies cannot fully
compensate Employer and its successors and assigns for such a violation and that
Employer and its successors and assigns shall be entitled to injunctive relief
to prevent violation or continuing violation hereof.  It is the intent and
understanding of each party hereto that if, in any action before any court or
agency legally empowered to enforce this covenant, any term, restriction,
covenant or promise is found to be unreasonable and for that reason
unenforceable, then such term, restriction, covenant or promise shall be deemed
modified to the extent necessary to make it enforceable by such a court or
agency.

         10.  Arbitration.
              -----------

claim arising out of or relating to this Agreement or the breach thereof shall
be settled by arbitration in Wilmington, Delaware, in accordance with the rules
of the American Arbitration Association and any decision made in accordance with
such rules shall be binding on all parties in interest, and judgment upon any
award rendered may be entered in any court having jurisdiction thereof.

         11.  Waiver of Breach.
              ---------------- 

              The waiver by Employer or Executive, as the case may be, of a
breach of any provision of this Agreement by Executive or Employer, as the case
may be, will not operate or be construed as a waiver of any subsequent breach by
Executive or Employer, as the case may be.

         12.  Entire Agreement.
              ---------------- 

              This instrument contains the entire Agreement of the parties with
respect to the employment of Executive by Employer.  It may not be changed
orally, but only by an agreement in writing signed by the party against whom
enforcement of any waiver, change, modification, extension or discharge is
sought.

         13.  Severability.
              ------------ 

              If any provision of this Agreement shall be invalid or
unenforceable, in whole or in part, such provision shall be deemed to be
modified or restricted to the extent and in the manner necessary to render the
same valid and enforceable, or shall be deemed excised from this Agreement, as
the case may require, and this Agreement shall be construed and enforced to the
maximum extent permitted by law, as if such provision had been originally
incorporated

                                      A-8

herein as so modified or restricted, or as if such provision had not been
originally incorporated herein, as the case may be.

violation of law, (iii) under Section 174 of the General Corporation Law of the 
State of Delaware, as the same exists or hereafter may be amended, or (iv) for 
any transaction from which such director derived an improper personal benefit.  
If the General Corporation Law of the State of Delaware is amended after the 
filing of this Certificate of Incorporation so as to authorize corporate actions
further eliminating or limiting personal liability of directors, then the 
liability of each director of the corporation shall be eliminated or limited to 
the fullest extent permitted by the law of the State of Delaware as the same 
exists from time to time.  Any repeal or modification of this paragraph by the 
stockholders of the corporation shall be prospective only and shall not 
adversely affect any limitation of the personal liability of a director of the 
corporation existing at the time of such repeal or modification.

            Pursuant to Section 151 of the General Corporation Law
                           of the State of Delaware

                         -----------------------------

     SP Acquisition Co., a Delaware corporation (the "Corporation"), certifies 
that pursuant to the authority contained in Article IV of its Certificate of 
Incorporation and in accordance with Section 151 of the General Corporation Law 
of the State of Delaware, its Board of Directors has adopted the following 
resolution creating a series of its Preferred Stock, par value $0.01 per share 
("Preferred Stock"), designated as Class A Preferred Stock:

     RESOLVED, that a series of the class of authorized Preferred Stock of the 
Corporation be, and it hereby is, created, and that the designation and amount 
thereof and the voting powers, preferences and relative, participating, optional
and other special rights, and the qualifications, limitations or restrictions 
thereof are as follows:

     Section 1.     Designation and Amount.
                    ----------------------

     The shares of such series shall be designated as "Class A Preferred Stock" 
(the "Class A Preferred Stock") and the number of shares constituting such 
series shall be Twenty-Two Thousand Three Hundred Fifteen (22,315), which 
number may be decreased (but not increased) by the Board of Directors without a 
vote of stockholders; provided, however, that such number may not be decreased 
below the number of then outstanding shares of Class A Preferred Stock.

     Section 2.     Dividends and Distributions.
                    ---------------------------

     Each holder of the Class A Preferred Stock shall be entitled to receive 
dividends on each share of Class A Preferred Stock on the same basis, and at the
same times and amounts, as the holder of one share of Common Stock.
<PAGE>
 
     Section 3.      Voting Rights.
                     -------------

     The holders of shares of Class A Preferred Stock, voting in person or by 
proxy, shall be entitled to vote upon all matters submitted to a vote of the 
shareholders of the Corporation and shall be entitled to one vote for each share
of Class A Preferred Stock held. Except as otherwise provided by law, the 
holders of Common Stock and the holders of the Class A Preferred Stock shall 
vote together as one class.

     Section 4.      Shares Acquired or Converted.
                     ----------------------------

     Any shares of the Class A Preferred Stock purchased or otherwise acquired
by the Corporation in any manner whatsoever, or converted in accordance with
Section 6, shall be retired and cancelled promptly after the acquisition or
conversion thereof. Any such shares shall not upon their cancellation be
reissued, and upon compliance with the requirements of the General Corporation
Law of the State of Delaware any such shares may be eliminated as part of the
authorized capital stock of the Corporation.

     Section 5.      Liquidation, Dissolution or Winding Up.
                     --------------------------------------

     (A)  Upon any liquidation, dissolution or winding up of the Corporation, 
whether voluntary or involuntary, no distribution shall be made to the holders 
of Common Stock or any other stock ranking junior (upon liquidation, dissolution
or winding up) to the Class A Preferred Stock unless, prior thereto, the holders
of the Class A Preferred Stock shall have received $22.406453 per share (rounded
to the nearest whole cent) or (B) to the holders of stock ranking on a parity 
(upon liquidation, dissolution or winding up) with the Class A Preferred Stock, 
except distributions made ratably on the Class A Preferred Stock and all other 
such parity stock in proportion to the total amounts to which the holders of all
such shares are entitled upon such liquidation, dissolution or winding up. Upon 
the completion of the distribution required by the immediately preceding 
sentence, if assets remain in the Corporation, the holders of Class A Preferred 
Stock shall be entitled to participate on the basis of the number of shares of 
Common Stock into which a share of Class A Preferred Stock is convertible on the
record date of such action; and

     (B)  Neither the consolidation, merger or other business combination of the
Corporation with or into any other person or persons nor the sale of all of the 
assets of the Corporation shall be deemed to be a liquidation, dissolution or 
winding up of the Corporation for purposes of this Section 5.

                                     - 2 -

     Section 6.     Conversion.
                    ----------

     (A)  Each share of the Class A Preferred Stock shall be convertible at the
option of the holder thereof into one fully paid and nonassessable share of
Common Stock of the Corporation.

     (B)  The holder of any shares of Class A Preferred Stock may exercise his 
right to convert such shares into shares of Common Stock by surrendering for 
such purpose to the Corporation, at its principal office or at such other office
or agency maintained by the Corporation for that purpose, a certificate or 
certificates representing the shares of Class A Preferred Stock to be converted 
accompanied by a written notice stating that such holder elects to convert all 
or a specified whole number of such shares in accordance with the provisions of 
this Section 6 and specifying the name or names in which such holder wishes the 
certificate or certificates for shares of Common Stock to be issued.  In case 
such notice shall specify a name or names other than that of such holder, such 
notice shall be accompanied by payment of all transfer taxes payable upon the 
issuance of shares of Common Stock in such name or names.  Other than such 
taxes, the Corporation will pay any and all issue and other taxes (other than 
taxes based on income) that may be payable in respect of any issue or delivery 
of shares of Common Stock on conversion of Class A Preferred Stock pursuant 
hereto.  As promptly as practicable, and in any event within thirty business 
days after the surrender of such certificate or certificates and the receipt of 
such notice relating thereto and, if applicable, payment of all transfer taxes 
(or the demonstration to the satisfaction of the Corporation that such taxes 
have been paid), the Corporation shall deliver or cause to be delivered (i) 
certificates representing the number of validly issued, fully paid and
nonassessable full shares of Common Stock to which the holder of shares of Class
A Preferred Stock so converted shall be entitled and (ii) if less than the full
number of shares evidenced by the surrendered certificate or certificates are
being converted, a new certificate or certificates, of like tenor, for the
number of shares evidenced by such surrendered certificate or certificates less
the number of shares converted. Such conversion shall be deemed to have been
made at the close of business on the date of giving of such notice and of such
surrender of the certificate or certificates representing the shares of Class A
Preferred Stock to be converted so that the rights of the holder thereof as to
the shares being converted shall cease except for the right to receive shares of
Common Stock in accordance herewith, and the person entitled to receive the
shares of Common Stock shall be treated for all purposes as having become the
record holder of such shares of Common Stock at such time. The Corporation shall
not be required to convert, and no surrender of shares of Class A Preferred
Stock shall be effective for that purpose, while the transfer books of the
Corporation for the Common Stock are closed for any purpose (but not for any
period in excess of 15 days);

                                     - 3 -
<PAGE>
 
but the surrender of shares of Class A Preferred Stock for conversion during any
period while such books are so closed shall become effective for conversion 
immediately upon the reopening of such books, as if the conversion had been made
on the date such shares of Class A Preferred Stock were surrendered.

     (C)  Upon conversion of any shares of Class A Preferred Stock, the holder 
thereof shall be entitled to receive any dividends on such shares of Class A 
Preferred Stock declared prior to such conversion if such holder held such 
shares on the record date fixed for the determination of holders of shares of 
Class A Preferred Stock entitled to receive payment of such dividends.

     (D)  The Corporation shall at all times reserve and keep available out of 
its authorized and unissued Common Stock, solely for the purpose of effecting 
the conversion of the Class A Preferred Stock, such number of shares of Common 
Stock as shall from time to time be sufficient to effect the conversion of all 
then outstanding shares of Class A Preferred Stock.  The Corporation shall from 
time to time, subject to and in accordance with the laws of Delaware (including 
using its best efforts to obtain the requisite consent of the shareholders of 
the Corporation), increase the authorized amount of Common Stock if at any time
the number of authorized shares of Common Stock remaining unissued shall not be
sufficient to permit the conversion at such time of all then outstanding shares
of Class A Preferred Stock.

Designation to be duly executed by its President and attested to by its 
Secretary and has caused its corporate seal to be affixed hereto, this 16th day 
of February, 1994.

Inspectors need not be stockholders.  No director or nominee for the office of 
director shall be appointed such an inspector.

corporation, any constituent corporation (including any constituent of a 
constituent) absorbed in a consolidation or merger which, if its separate

or an Assistant Treasurer of the Corporation, and sealed with the seal of the

                                GENERAL BY LAWS
                                ---------------

                                 SHAREHOLDERS
                                 ------------

1.   Annual meeting.  The annual meeting of the shareholders of the Company 
     --------------
     shall be held on such date, not later than 4 months after the close of the
     Company's preceding financial year, as the directors may from time to time
     by resolution provide, for the election of directors and the transactions
     of such other business as may properly come before the meeting.

          The annual meeting shall be held at the head office of the Company, or
     at such other place as may be fixed by the directors.

2.   Special general meetings.  Special general meetings of shareholders may be 
     ------------------------
     called at any time by order of the Chairman of the Board or the President
     or any Vice-President of the Company or under authority of a resolution of
     the board of directors or shall be called whenever the holders of not less
     than one-tenth of the outstanding shares of the Company carrying voting
     rights at such meeting shall, in writing, request the same. Any such
     order, resolution or request shall specify the object for which the meeting
     is to be called. The notice of a special general meeting shall state in
     general terms the purpose or purposes of the meeting.

          It shall be the duty of the President or, in his absence, of one of 
     the Vice-Presidents, upon adoption of such a resolution or on receipt of
     such a request to cause the meeting to be called by the Secretary or other
     officer of the Company in conformity with the terms of the resolution or
     request. In default of his so doing, any director may call such meeting or
     the same may be called by such shareholders themselves in accordance with
     and

<PAGE>
 
        subject to the provisions of the laws governing the Company.

             Special general meetings of shareholders shall be held at the head 
        office of the Company or at any other place or places within or without 
        Canada previously approved by resolution of the directors or at any 
        other place where all the shareholders of the Company entitled to vote 
        thereat are present in person or represented by proxy or of which all 
        the shareholders of the Company approve.

3.      Notice of meetings.  Notice specifying the place, day and time of each
        ------------------
        annual and of each special general meeting of shareholders shall be
        given by sending the notice to each shareholder entitled to vote at the
        meeting through the post, in a prepaid wrapper or letter not less than
        14 days or more than 60 days before the date of the meeting, to his
        latest address as shown on the books of the Company. Where required by
        law, such notice shall be accompanied by a copy of the Company's
        financial statements and a copy of the auditor's report.

             Notice of the time and place for holding any meeting of 
        shareholders need not be given if all the shareholders of the Company 
        entitled to vote at the meeting waive notice of the meeting in writing.

             Notices with respect to any shares registered in more than one name
        shall be given to whichever of such persons is named first in the books
        of the Company in respect of such joint holding and notice so given 
        shall be sufficient notice to all the holders of such shares.

             Irregularities in the notice or in the giving thereof, as well as 
        the accidental omission to give notice of any meeting to, or the 
        non-receipt of any such notice by any of the shareholders, shall not 
        invalidate any proceedings at any such meeting.  A certificate of the 
        Secretary or of any other duly authorized officer of the Company or of 
        any officer or any transfer agent or registrar of the Company with 
        respect to the mailing of any notice shall be conclusive evidence 
        thereof and shall be binding on every shareholder.
<PAGE>
 
4.      Quorum, voting and adjournments. One or more persons, each of whom shall
        -------------------------------
        be entitled to vote thereat either personally or as proxy or as the
        authorized representative of a corporation holding at least one share
        carrying voting rights thereat, and representing in their own right or
        by proxy or as such authorized representative or representatives not
        less than 50% in number of the outstanding shares of the capital stock
        of the Company carrying voting rights at such meeting, shall constitute
        a quorum for an annual meeting and for a special general meeting,
        provided, however that if, all the shares entitled to vote at a meeting
        are held by one holder, the holder present, in person or by proxy
        constitutes a meeting.

             The act of the holders of a majority of the shares so represented
        and carrying voting rights thereat shall be the act of the shareholders
        except where the vote or consent of the holders of a greater number of
        shares is required by the laws governing the Company, the Articles of
        the Company or by the by-laws of the Company.

             Should a quorum not be present at any meeting of shareholders,
        those present in person and entitled to be counted for the purpose of
        forming a quorum shall have power to adjourn the meeting from time to
        time without notice other than announcement at the meeting until a
        quorum shall be present. At any such adjourned meeting, provided a
        quorum is present, any business may be transacted which might have been
        transacted at the meeting adjourned.

5.      Right to vote and proxies. At any meeting of shareholders, each
        -------------------------
        shareholder entitled to vote thereat, and each authorized representative
        of a corporation holding at least one share carrying voting rights
        thereat, who shall be present at such meeting, shall have on a show of
        hands one vote, and upon a poll each shareholder present in person or
        represented by proxy and the authorized representative of a corporation
        present in person or represented by proxy shall be entitled to one vote
        for each share carrying voting rights at such meeting registered in his
        or its name on the books of the Company unless, under the terms of the
        articles incorporating the Company or any articles thereto, some other
        scale of voting is fixed, in

<PAGE>
 
        which event such scale of voting shall be adopted. Any shareholder or
        proxy or the authorized representative of a corporation entitled to vote
        at any meeting of shareholders may demand a poll in respect of any
        matter submitted to a vote. A poll need not be preceded by a show of
        hands.

                Shareholders (including corporations) entitled to vote may vote
        upon a poll by proxy at any meeting of the shareholders, and the
        representative of a corporation entitled to vote may likewise vote by
        proxy if duly authorized in that behalf by such corporation. The holder
        of any proxy need not himself be a shareholder entitled to vote at the
        meeting.

                The directors may by resolution fix a time not exceeding 48 
        hours, excluding Saturdays and holidays, preceding any meeting or
        adjourned meeting of shareholders before which time proxies to be used
        at that meeting must be deposited with the Company or an agent thereof,
        and any period of time so fixed shall be specified in the notice calling
        the meeting.

6.      Joint shareholders.  Where there are joint registered holders of any 
        ------------------
        share or shares any one of such persons may vote at any meeting either
        personally or by proxy in respect of such share or shares as if he were
        solely entitled thereto unless more than one of such joint holders be
        present or represented by proxy at such meeting, in which event that one
        of such joint holders so present or represented whose name stands first,
        or before the other or others, on the books of the Company in respect of
        such share or shares shall alone be entitled to vote in respect thereof.
        Several executors or administrators of a deceased shareholder in whose
        name any share stands shall for the purpose of this paragraph be deemed
        joint holders thereof.

7.      Procedure at meetings.  The chairman of any meeting of shareholders 
        ---------------------
        shall conduct the procedure thereat in all respects and his decision on
        all matters or things, including, but without in any way limiting the
        generality of the foregoing, any question
<PAGE>
 
     regarding the validity or invalidity of any instruments of proxy, shall be
     conclusive and binding upon the shareholders.

          A declaration by the chairman at any meeting that a resolution has 
     been carried or carried unanimously or carried by any particular majority
     or lost or not carried by a particular majority shall be conclusive
     evidence of the fact.
     
          The chairman at any meeting of shareholders may vote as a shareholder 
     but shall not have a second or casting vote in case of an equality of 
     votes.

8.   Scrutineers.  The chairman at any meeting of shareholders may appoint one 
     -----------
     or more persons (who may but need not be shareholders, directors, officers
     or employees of the Company) to act as scrutineers at such meeting.

9.   Resolutions.  All motions or resolutions of shareholders shall be passed at
     -----------
     duly convened meetings. The signature of all the shareholders of the
     Company entitled to vote thereon to any instrument (which may be signed in
     counterparts) setting out a motion or resolution which might be passed by
     the shareholders shall give to the motion or resolution the same force and
     effect as if it had been unanimously passed by all the shareholders
     entitled to vote at a meeting held to consider the same.

                                   DIRECTORS
                                   ---------

10.  Term of office.  Each director shall (except as herein otherwise provided) 
     --------------
     be elected at the annual meeting of shareholders by a majority of the votes
     cast in respect of such election. It shall not be necessary that the voting
     for the election of directors of the Company be conducted by poll, unless
     voting by poll is demanded by someone present and entitled to vote at such
     meeting. Each director so elected shall hold office until the election of
     his successor unless he shall resign or his office become vacant by death,
     removal or other cause.

<PAGE>
 
11.     General powers of directors. The directors may administer the affairs of
        ---------------------------
        the Company in all things and may make or cause to be made for the
        Company, in its name, any contract which the Company may lawfully enter
        into and generally may exercise all such other powers and do all such
        other acts and things as the Company is by its charter or otherwise
        entitled to exercise and do.

                Without in any way derogating from the foregoing, the directors
        are expressly empowered to purchase, lease or otherwise acquire,
        alienate, sell, exchange or otherwise dispose of shares, stocks, rights,
        warrants, options, bonds, debentures and other securities, lands,
        buildings, patents and any and all other property, moveable or
        immoveable, real or personal, or any right or interest therein, owned by
        the Company, for such consideration and upon such terms and conditions
        as they may deem advisable.

                All acts done by any meeting of directors or by any person
        acting as a director, so long as his successor shall not have been duly
        elected or appointed, shall, notwithstanding that it be afterwards
        discovered that there was some defect in the election of the directors
        or the person acting as aforesaid or that they or any of them were
        disqualified, be as valid as if the directors or such other person, as
        the case may be, had been duly elected and were or was qualified to be
        directors or a director of the Company.

12.     Power to allot stock and grant options. The shares of the Company shall
        --------------------------------------
        be at all times under the control of the directors who may by resolution
        accept subscriptions for, allot, issue, grant options in respect of and
        otherwise dispose of the whole or any part of the unissued shares of the
        Company to such directors, officers, employees, persons, firms,
        companies or corporations on such terms and conditions, for such
        consideration not contrary to law or to the charter of the Company and
        at such times as the directors shall prescribe.

                In respect of any shares issued otherwise than as fully paid,
        and subject to the terms of issue thereof, the directors may make calls
        upon the shareholders in respect of any moneys unpaid upon
        
<PAGE>
 
        such shares. Each shareholder shall pay the amount so called on such
        shares at the time or times and at the place fixed by the directors.
        Interest shall run on the amount of each call at the rate of 6% per
        annum from the date appointed for the payment of such call to the time
        of actual payments.

13.     Power to declare dividends. The directors may, as they deem advisable,
        --------------------------
        declare and pay dividends out of any funds available for dividends to
        the shareholders according to their respective rights and interests
        therein.

                The dividends payable upon any share which is not fully paid
        shall be reduced by a proportion equal to that proportion of the full
        consideration for such share which has not been paid. No amount paid on
        a share in advance of call shall, while carrying interest, be treated
        for the purpose of this by-law as paid on the share.

                The directors may, before declaring any dividend or making any
        distribution of profits, set aside out of the profits of the Company
        such sums as they think proper as a reserve or reserves which shall in
        the absolute discretion of the directors be applicable for any purpose
        which they shall think conducive to the best interest of the Company.

14.     Time of meetings and notices. As soon as may be practicable after the
        -----------------------------
        annual meeting of shareholders in each year there shall be held, without
        notice, a meeting of such of the newly elected directors as are then
        present, provided they shall constitute a quorum, for the election or
        appointment of officers of the Company and for the transaction of such
        other business as may come before the meeting.

                Regular meetings of the directors may be held at such place, at
        such time and upon such notice, if any, as the directors may determine.
<PAGE>
 
                Special meetings of the directors may be called at any time by
        or by order of the Chairman of the Board, the President or any two
        directors, and may be held at the head office of the Company, or at such
        other place as the directors may determine. Notice specifying the
        place, day and time of each such meeting shall be served upon each
        director or left at his usual residence or usual place of business, or
        shall be mailed, telegraphed or cabled prepaid, addressed to each
        director at his address as it appears on the books of the Company at
        least 48 hours prior to the time fixed for such meeting in the case of
        notice served personally or telegraphed or cabled, and at least 72 hours
        prior to the time fixed for such meeting in other cases. 

                No notice of any regular or special meeting of the directors
        need specify the purposes for which it is called or the nature of the
        business to be transacted.

                A meeting of the directors may be held at any time and place and
        for any purpose without notice when all the directors are present or
        when all directors not present shall have, in writing or by telegram or
        cable, waive notice of such meeting either before or after such meeting
        is held.

                The directors may participate in a meeting of the board of
        directors by such means, particularly by telephone, as permit all
        directors participating in the meeting to hear each other and a director
        participating in such meeting by such means is deemed to be present at
        such meeting.

15.     Quorum and voting. The directors may from time to time fix the
        -----------------
        quorum for meetings of directors, but unless so fixed a majority of the
        directors in office shall constitute a quorum.

                Questions arising at any meeting of the directors shall be
        decided by a majority of the votes of those present. The chairman of the
        meeting may vote as a director but shall not have a second or casting
        vote in respect of any matter submitted to the vote of the meeting.


<PAGE>
 
16.     Vacation of office.  The office of a director shall automatically be 
        ------------------
        vacated:

        16.1    if he ceases to be qualified for such office;

        16.2    if by notice in writing to the Company he resigns his office;

        16.3    if he dies; or

        16.4    if he is removed at any meeting of shareholders called for the
        purpose.
        
17.     Vacancies. In the case of a vacancy occurring in the number of directors
        ---------
        as elected by the shareholders, the directors then in office, by the
        affirmative vote of a majority thereof, whether or not such majority
        constitutes a quorum, may elect any other duly qualified person as a
        director and any director so elected shall hold office until the next
        annual meeting of shareholders and shall then be eligible for 
        re-election.

18.     Remuneration of directors. The directors shall have power to fix the
        -------------------------
        remuneration to be paid to directors for their services as such, which
        remuneration shall be in addition to any salary a director may receive
        as an officer or employee of the Company. The directors shall also be
        entitled to be paid their travelling and other expenses properly
        incurred by them in connection with the affairs of the Company, or to
        receive a fixed allowance in respect thereof.

19.     By-laws and resolutions. All by-laws and resolutions of directors shall
        -----------------------
        be enacted or adopted at duly convened meetings.  Notwithstanding the
        foregoing, the signature of all the directors of the Company to any
        instrument (which may be signed in counterparts) setting out a by-law or
        resolution which might be enacted or adopted by the directors shall give
        to such by-law or resolution the same force and effect as if it had been
        unanimously enacted or adopted, as the case may be, by vote of the
        directors at a meeting duly convened and held.

<PAGE>
 
20.   Indemnities of directors and others. Every director and officer of the
      -----------------------------------
      Company shall be deemed to have assumed office on the express
      understanding and agreement and condition that he and his heirs, executors
      and administrators and estate and effects respectively shall from time to
      time and at all times be indemnified and saved harmless out of the funds
      of the Company from and against all costs, charges and expenses whatsoever
      which such director or officer sustains or incurs in or about any action,
      suit or proceeding which is brought, commenced or prosecuted against him
      or them for or in respect of any act, deed, matter or thing whatsoever
      made, done or permitted by him in or about the execution of the duties of
      his office, and also from and against all other costs, charges and
      expenses which he sustains or incurs in or about or in relation to the
      affairs thereof, except such costs, charges or expenses as are occasioned
      by his own wilful neglect or default.

           The directors of the Company may cause the Company to give 
      indemnities to any director or other person who has undertaken or is about
      to undertake any liability on behalf of the Company or any corporation
      controlled by it and to secure such director or other person against loss
      by mortgage and charge upon the whole or any part of the real and personal
      property of the Company by way of security, and any action taken by the
      directors under this paragraph shall not require approval or confirmation
      by the shareholders.


                              EXECUTIVE COMMITTEE
                              -------------------

21.   Election and powers. The board of directors, whenever it consists of more
      ------------------- 
      than six, may elect from time to time from their number an executive
      committee consisting of such number of members (not less than three) as
      the board may by resolution from time to time determine. Each member of
      the executive committee shall hold office during the pleasure of the
      board.

           The board may from time to time by resolution remove any member
      without cause or add to or otherwise change the membership of the
      executive


      

      
<PAGE>
 
        committee and may adopt rules or regulations relating to the calling,
        holding and quorum at meetings of the executive committee and the
        procedure thereat.

             The executive committee shall have and may exercise all the powers 
        of the board of directors; provided, however, that the executive 
        committee shall at no time have power to allot, or grant options with 
        respect to, shares of capital stock, remove or replace directors, 
        declare or authorize payment of dividends or enact, amend or repeal 
        by-laws.

                                   OFFICERS
                                   --------

22.     Officers.  The executive officers of the Company shall be the 
        --------
        President, a Treasurer and a Secretary.  The President, Treasurer and 
        Secretary shall be elected or appointed by the board of directors at its
        first meeting after the first meeting of the shareholders and thereafter
        at the first or any subsequent meeting of the board of directors held
        after each annual meeting of shareholders. The board of directors may
        also elect or appoint at any time and from time to time as officers or
        executive officers a Chairman of the Board, one or more Vice-Presidents,
        one or more Assistant-Secretaries, one or more Assistant-Treasurers, a
        Comptroller, a General Manager or Managing Director and such other
        officers or executive officers as the board of directors, from time to
        time, deem expedient. All officers and executive officers of the Company
        shall hold office until their successors are chosen and, when necessary,
        qualified in their stead, subject always to removal as provided in the
        by-laws of the Company. All officers and executive officers shall
        respectively perform such duties, in addition to those specified in the
        by-laws of the Company, as shall, from time to time, be prescribed by
        the board of directors. The same person may hold more than one office,
        provided, however, that the offices of President and Vice-President
        shall not be held by the same person. None of such officers or executive
        officers of the Company except the Chairman of the Board and the
        President
<PAGE>
 
        and the Managing Director need be a director of the Company.

23.     Chairman of the Board.  The Chairman of the Board shall be chosen from 
        ---------------------
        among the directors. He shall preside at all meetings of shareholders
        and at all meetings of directors and he shall have such other powers and
        duties as the board of directors may determine, from time to time, by
        resolution.

24.     President.  The President shall be chosen from among the directors.  
        ---------
        In the absence of the Chairman of the Board, he shall preside at all
        meetings of the shareholders and at all meetings of the board of
        directors. He shall be the chief executive officer of the Company and,
        if no General Manager or Managing Director is appointed, shall exercise
        a general control of and supervision over its affairs. He shall have
        such other powers and duties as the board of directors may determine,
        from time to time, by resolution.

        as indemnity against any claim that may be made against them or any of
        them for or in respect of the shares represented by the certificate
        alleged to have been lost, stolen, defaced or destroyed, a new
        certificate may be issued in replacement of the one so alleged to have

giving effect on a pro forma basis to such Indebtedness as if such Indebtedness
had been issued on the first day of such period and the discharge of any other
Indebtedness repaid, repurchased, defeased or otherwise discharged with the
proceeds of such new Indebtedness as if such discharge had occurred on the first
day of such period, (B) if since the beginning of such period the Company or any
Restricted Subsidiary has made any Asset Sale, EBITDA for such period shall be

period shall be reduced by an amount equal to the Consolidated Interest Expense

made under the Indenture, which constitutes all or substantially all of an

incurrence of any Indebtedness) as if such Investment or acquisition occurred on
the first day of such period and (D) in making such computation, Consolidated
Interest Expense attributable to any Indebtedness incurred under any revolving
credit facility shall be computed based on the average daily balance of such
Indebtedness during such period.  For purposes of this definition, whenever pro
forma effect is to be given to an acquisition of assets, the amount of income or
earnings relating thereto, and the amount of Consolidated Interest Expense
associated with any Indebtedness incurred in connection therewith, the pro forma
calculations shall be determined in good faith by a responsible financial or
accounting officer of the Company.  If any Indebtedness bears a floating rate of

shall be calculated as if the rate in effect on the date of determination had
been the applicable rate for the entire period.

          (c) a statement that, in the opinion of each such individual, such
     individual has made such examination or investigation as is necessary to
     enable him to express an informed opinion as to whether or not such
     covenant or condition has been complied with; and

          (d) a statement as to whether, in the opinion of each such individual,
     such condition or covenant has been complied with.

          Section 104.   Form of Documents Delivered to Trustee.
                         -------------------------------------- 

          In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

          Any certificate or opinion of an officer of the Company, any Guarantor
or other obligor of the Securities may be based, insofar as it relates to legal
matters, upon a certificate or opinion of, or representations by, counsel,
unless such officer knows that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous.  Any such certificate or opinion may be based, insofar as it relates
to factual matters, upon a certificate or opinion of, or representations by, an
officer or officers of the Company, any Guarantor or other obligor of the
Securities stating that the information with respect to such factual matters is
in the possession of the Company, any Guarantor or other obligor of the
Securities, unless such counsel knows that the certificate or opinion or
representations with respect to such matters are erroneous.  Opinions of Counsel
required to be delivered to the Trustee may have qualifications customary for
opinions of the type required and counsel delivering such Opinions of Counsel
may rely on certificates of the Company or government or other officials
customary for opinions of the type required, including certificates certifying
as to matters of fact, including that various financial covenants have been
complied with.

          Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

          Section 105.   Acts of Holders.
                         --------------- 

          (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly

                                    - 26 -
<PAGE>
 
provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee and, where it is hereby expressly required, to the
Company.  Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the Holders
signing such instrument or instruments.  Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture, if made in the manner provided in this Section.  The
fact and date of the execution by any Person of any such instrument or writing
or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee deems sufficient in accordance with such
reasonable rules as the Trustee may determine.

          (b) The ownership of Securities shall be proved by the Register.

          (c) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any Security shall bind every future
Holder of the same Security or the Holder of every Security issued upon the
transfer thereof or in exchange therefor or in lieu thereof, in respect of
anything done, suffered or omitted to be done by the Trustee, any Paying Agent
or the Company or any Guarantor in reliance thereon, whether or not notation of
such action is made upon such Security.

          (d) If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may,
at its option, by or pursuant to a Board Resolution, fix in advance a record
date for the determination of such Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so.  Notwithstanding Trust Indenture Act
Section 316(c), any such record date shall be the record date specified in or
pursuant to such Board Resolution, which shall be a date not more than 30 days
prior to the first solicitation of Holders generally in connection therewith and
no later than the date such solicitation is completed.

          In the absence of any such record date fixed by the Company,
regardless as to whether a solicitation of the Holders is occurring on behalf of
the Company or any Holder, the Trustee may, at its option, fix in advance a
record date for the determination of such Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other Act, but the
Trustee shall have no obligation to do so.  Any such record date shall be a date
not more than 30 days prior to the first solicitation of Holders generally in
connection

                                     -27-
<PAGE>
 
therewith and no later than a date such solicitation is completed.

          If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be given before or after
such record date, but only the Holders of record at the close of business on
such record date shall be deemed to be Holders for purposes of determining
whether Holders of the requisite proportion of Securities then outstanding have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other Act, and for this purpose the
Securities then Outstanding shall be computed as of such record date; provided
that no such request, demand, authorization, direction, notice, consent, waiver
or other Act by the Holders on such record date shall be deemed effective unless
it shall become effective pursuant to the provisions of this Indenture not later
than six months after the record date.

                         ----------------------------------------------
Subsidiary Guarantor.
- -------------------- 

          Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with:

          (a) the Trustee by any Holder or by the Company or any Guarantor or
     any other obligor of the Securities shall be sufficient for every purpose
     hereunder if in writing (including telecopy, with respect to the Company or
     any Subsidiary Guarantor only) and mailed, first-class postage prepaid,
     telecopied, hand delivered, or delivered by recognized overnight courier,
     to or with the Trustee at First Union National Bank, Broad & Walnut
     Streets, PA1249, Philadelphia, Pennsylvania, Attention: Corporate Trust
     Administration or at any other address previously furnished in writing to
     the Holders, the Company, any Guarantor or any other obligor of the
     Securities by the Trustee; or

          (b) the Company or any Guarantor shall be sufficient for every purpose
     hereunder if in writing (including telecopy) and mailed, first-class
     postage prepaid, telecopied, hand delivered, or delivered by recognized
     overnight courier, to the Company or such Guarantor addressed to it at
     Three Radnor Corporate Center, Suite 300, 100 Matsonford Road, Radnor,
     Pennsylvania, 19087, Attention: Treasurer, telecopy: (610) 995-2697 or at
     any other address previously furnished in writing to the Trustee by the
     Company or such Guarantor.

          Section 107.  Notice to Holders; Waiver.
                        ------------------------- 

          Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, or delivered by
recognized overnight courier, to each Holder affected by such event, at his
address as it appears in the Security Register, not later than the latest date,
and not earlier than the earliest date, prescribed for the giving of such
notice.  In any case where notice to Holders is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders.  Any notice when mailed to a Holder in the aforesaid manner shall
be conclusively deemed to have been received by such Holder whether or not
actually received by such Holder.  Where this Indenture provides for notice in
any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

          In case by reason of the suspension of regular mail service or by
reason of any other cause, it shall be impracticable to mail notice of any event
as required by any provision of this Indenture, then any method of giving such
notice as shall be reasonably satisfactory to the Trustee shall be deemed to be
a sufficient giving of such notice.

          Section 108.   Conflict with Trust Indenture Act.
                         --------------------------------- 

          If any provision hereof limits, qualifies or conflicts with any
provision of the Trust Indenture Act or another provision which is required or
deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, the provision or requirement of the Trust Indenture Act shall
control.  If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or to be
excluded, as the case may be.

          Section 109.   Effect of Headings and Table of Contents.
                         ---------------------------------------- 

          The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

          Section 110.  Successors and Assigns.
                        ---------------------- 

          All covenants and agreements in this Indenture by the Company and the

          Section 111.   Separability Clause.
                         ------------------- 

          In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

          Section 112.   Benefits of Indenture.
                         --------------------- 

          Nothing in this Indenture or in the Securities or the Guarantees,
express or implied, shall give to any Person (other than the parties hereto and
their successors hereunder, any Paying Agent and the Holders) any benefit or any
legal or equitable right, remedy or claim under this Indenture.

          Section 113.   Governing Law.
                         -------------

          Section 114.   Legal Holidays.
                         -------------- 

          In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day, then (notwithstanding any
other provision of this Indenture or of the Securities) payment of interest or
principal or premium, if any, need not be made on such date, but may be made on
the next succeeding Business Day with the same force and effect as if made on
the Interest Payment Date, Redemption Date or at the Stated Maturity and no
interest shall accrue with respect to such payment for the period from and after
such Interest Payment Date, Redemption Date or Stated Maturity, as the case may
be, to the next succeeding Business Day.

          Section 115.   Schedules and Exhibits.
                         ---------------------- 

          All schedules and exhibits attached hereto are by this reference made

                         ------------ 

          This Indenture may be executed in any number of counterparts, each of
which shall be an original; but such

                                    - 30 -

counterparts shall together constitute but one and the same instrument.

          Section 117.   Communication by Holders with Other Holders.
                         ------------------------------------------- 

          Holders may communicate pursuant to Trust Indenture Act Section 312(b)

Securities.  The Company, the Guarantors, the Trustee, the Registrar and anyone
else shall have the protection of Trust Indenture Act Section 312(c).

the Company under the Securities or this Indenture, for any obligation of the
Guarantors under the Guarantees or this Indenture or for any claim based on, in
respect of or by reason of such obligations or their creation.  By accepting a
Security, each Holder shall waive and release all such liability.  The waiver
and release shall be part of the consideration for the issue of the Securities.

                                  ARTICLE TWO

                                 SECURITY FORMS

          Section 201.   Forms Generally.
                         --------------- 

          The Securities, the Guarantees and the Trustee's certificate of
authentication shall be in substantially the forms set forth in this Article,
with such appropriate insertions, omissions, substitutions and other variations
as are required or permitted by the Indenture and may have such letters, numbers
or other marks of identification and such legends or endorsements placed thereon
as may be required to comply with the rules of any securities exchange, any
organizational document or governing instrument or applicable law or as may,
consistently herewith, be determined by the officers executing such Securities,
as evidenced by their execution of the Securities.  Any portion of the text of
any Security may be set forth on the reverse thereof, with an appropriate
reference thereto on the face of the Security.

          Securities offered and sold in reliance on Rule 144A shall be issued
initially in the form of one or more permanent global securities substantially
in the form set forth in this Article (the "U.S. Global Security") deposited
with the Trustee, as custodian for the Depositary, duly executed by the Company
and authenticated by the Trustee as hereinafter provided.  The aggregate
principal amount of the U.S. Global Security may from

                                    - 31 -
<PAGE>
 
time to time be increased or decreased by adjustments made on the records of the
Trustee, as custodian for the Depositary or its nominee, as hereinafter
provided.

          Securities offered and sold other than as described in the preceding
paragraph shall be issued in the form of permanent certificated Securities in
registered form in substantially the form set forth in this Article (the
"Physical Securities").

          The definitive Securities shall be printed, lithographed or engraved
or produced by any combination of these methods or may be produced in any other
manner permitted by the rules of any securities exchange on which the Securities
may be listed, all as determined by the officers executing such Securities, as
evidenced by their execution of such Securities.

          Section 202.   Restrictive Legends.
                         ------------------- 

          Each U.S. Global Security and Physical Security shall bear the
following legend on the face thereof until after the Resale Restriction
Termination Date, unless and until a Security is exchanged for an Exchange Note
in connection with an effective registration pursuant to the Registration Rights
Agreement or another effective registration and resale of the Securities occurs
pursuant to the Registration Rights Agreement:

          THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF
1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS AND
ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING
SENTENCE.  BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A
"QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES
ACT) OR (B) IT IS AN INSTITUTIONAL INVESTOR THAT IS AN "ACCREDITED INVESTOR" (AS
DEFINED IN RULE 501(A)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT) (AN
"INSTITUTIONAL ACCREDITED INVESTOR"), (2) AGREES FOR THE BENEFIT OF THE COMPANY
THAT IT WILL NOT, WITHIN THREE YEARS AFTER THE LATER OF THE ORIGINAL ISSUANCE OF
THIS SECURITY OR THE LAST DATE ON WHICH THIS SECURITY WAS HELD BY AN AFFILIATE
OF THE COMPANY, RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE
COMPANY OR ANY SUBSIDIARY THEREOF, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN
COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) TO AN INSTITUTIONAL
ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO THE TRUSTEE A
SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE
RESTRICTIONS ON TRANSFER OF THIS SECURITY (THE FORM OF WHICH CAN BE OBTAINED
FROM THE TRUSTEE), (D) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY
RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (E) PURSUANT TO AN EFFECTIVE
REGISTRATION STATEMENT UNDER THE SECURITIES ACT, SUBJECT IN EACH OF THE
FOREGOING CASES TO ANY REQUIREMENT OF LAW THAT THE DISPOSITION OF SUCH HOLDER'S
PROPERTY OR THE PROPERTY OF SUCH ACCOUNT AT ALL TIMES BE WITHIN ITS

                                    - 32 -
<PAGE>
 
CONTROL AND TO COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS; AND (3) AGREES
THAT IT WILL DELIVER TO EACH PERSON TO WHOM  THIS SECURITY IS TRANSFERRED A
NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  IN CONNECTION WITH ANY
TRANSFER OF ANY CERTIFICATED SECURITY WITHIN THREE YEARS AFTER THE LATER OF THE
ORIGINAL ISSUANCE OF THE SECURITY OR THE LAST DATE ON WHICH SUCH CERTIFICATED
SECURITY WAS HELD BY AN AFFILIATE OF THE COMPANY, THE HOLDER MUST CHECK THE
APPROPRIATE BOX SET FORTH ON THE REVERSE OF SUCH CERTIFICATED SECURITY RELATING
TO THE MANNER OF SUCH TRANSFER AND SUBMIT SUCH CERTIFICATED SECURITY TO THE
TRUSTEE.  IF ANY PROPOSED TRANSFEREE IS AN ACCREDITED INVESTOR, THE HOLDER MUST,
PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE AND THE COMPANY SUCH
CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY
REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT OR APPLICABLE STATE SECURITIES LAWS.  THE
INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY
TRANSFER OF THIS SECURITY IN VIOLATION OF THE FOREGOING RESTRICTIONS.

          Each U.S. Global Security, whether or not an Exchange Note, shall also
bear the following legend on the face thereof:

     UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
     DEPOSITORY TRUST COMPANY, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF
     TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN
     THE NAME OF CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN
     AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY OR SUCH OTHER
     REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY OR SUCH OTHER NAME AS IS
     REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY
     (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO.), ANY TRANSFER, PLEDGE OR
     OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
     SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

     TRANSFER OF THIS U.S. GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN
     WHOLE, BUT NOT IN PART, TO NOMINEES OF CEDE & CO., OR TO A SUCCESSOR
     THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS U.S.
     GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE
     RESTRICTIONS SET FORTH IN SECTION 307 OF THE INDENTURE.

          Section 203.   Form of Face of Securities.
                         -------------------------- 

          The form of the face of the Securities shall be substantially as
follows:

CUSIP No. __________                                  $___________

          RADNOR HOLDINGS CORPORATION, a Delaware corporation (herein called the
"Company", which term includes any successor Person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
___________ or registered assigns, the principal sum of __________ United States
dollars on December 1, 2003, at the office or agency of the Company referred to
below, and to pay interest thereon from the date of original issuance, or from
the most recent Interest Payment Date to which interest has been paid or duly
provided for, semiannually on June 1 and December 1 in each year, commencing
June 1, 1997 at the rate of 10% per annum (subject to adjustment as provided
below), in United States dollars, until the principal hereof is paid or duly
provided for.

          [In the event that (i) the Exchange Offer Registration Statement is
not filed with the Commission on or prior to the 60th day after the Issue Date
or declared effective on or prior to the 120th day after the Issue Date, (ii)
the Exchange Offer is not consummated on or prior to the 150th day following the
Issue Date, (iii) the Shelf Registration Statement is not filed or declared
effective within the required time periods or (iv) any of the Registration
Statements required by the Registration Rights Agreement is declared effective
but thereafter ceases to be effective (except as specifically permitted therein)
for a period of 15 consecutive days without being succeeded immediately by any
additional Registration Statement filed and declared effective (each such event,
a "Registration Default"), the interest rate borne by the Securities will be
increased by 25 basis points per annum for the 90-day period following such
Registration Default.  Such interest rate shall increase by an additional 25
basis points per annum at the beginning of each subsequent 90-day period
following such Registration Default, up to a maximum aggregate increase of 100
basis points per annum and, accordingly, the maximum interest rate on the
Securities may not exceed 11%.  Upon (x) the filing or the effectiveness of the
Exchange Offer Registration Statement, (y) the consummation of the Exchange
Offer or (z) the filing or the effectiveness of the Shelf Registration
Statement, as the case may be, the interest rate borne by the Securities shall
be reduced from and including the date on which any of the events specified in
clauses (x), (y) or (z) above occur by the amount of the related increase in the
interest rate.

<PAGE>
 
          Notwithstanding the foregoing, the Issuers shall not be required to
pay such additional interest with respect to the Securities held by a Holder if
the applicable Registration Default arises from the failure of the Issuers to
file, or cause to become effective, a Shelf Registration Statement within the
specified time periods by reason of the failure of such Holder to provide such
information as (i) the Company may reasonably request, with reasonable prior
written notice, for use in the Shelf Registration Statement or any prospectus
included therein to the extent the Company reasonably determines that such
information is required to be included therein by applicable law, (ii) the
National Association of Securities Dealers, Inc. or the Commission may request
in connection with such Shelf Registration Statement or (iii) is required to
comply with the agreements of such Holder contained in the penultimate paragraph
of Section 5 of the Registration Rights Agreement to the extent compliance
thereof is necessary for the Shelf Registration Statement to be declared
effective.]/1/

          The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date shall, as provided in such Indenture, be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest, which shall be the May 15 and November 15 next preceding such Interest
Payment Date.  Any such interest not so punctually paid, or duly provided for,
and interest on such defaulted interest at the interest rate borne by the
Securities, to the extent lawful, shall forthwith cease to be payable to the
Holder on such Regular Record Date, and may be paid to the Person in whose name
this Security (or one or more Predecessor Securities) is registered at the close
of business on a Special Record Date for the payment of such defaulted interest
to be fixed by the Trustee, notice whereof shall be given to Holders of
Securities not less than 10 days prior to such Special Record Date, or may be
paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange on which the Securities may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in said Indenture.

          Payment of the principal of, premium, if any, and interest on this
Security shall be made at the office or agency of the Company maintained for
that purpose, in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that payment of interest may be made at the option of the

set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

          This Security is entitled to the benefits of Guarantees by each of the
Guarantors of the punctual payment when due of the Indenture Obligations made in
favor of the Trustee for the benefit of the Holders.  Such Guarantees shall be
senior unsecured obligations of each Guarantor, and will rank pari passu in
right of payment with all other existing and future Senior Indebtedness of such
Guarantor and senior to all Subordinated Indebtedness of such Guarantor.  Such
Guarantees will be effectively subordinated in right of payment to all existing
and future secured indebtedness of the Guarantors.  Reference is hereby made to

appointed as provided in the Indenture by manual signature, this Security shall
not be entitled to any benefit under the Indenture, or be valid or obligatory

          Section 204.   Form of Reverse of Securities.
                         ----------------------------- 

          The form of the reverse of the Securities shall be substantially as
follows:

          This Security is one of a duly authorized issue of Securities of the
Company designated as its 10% Senior Notes due 2003 (herein called the
"Securities"), limited (except as otherwise provided in the Indenture referred
to below) in aggregate principal amount to $100,000,000, which may be issued
under an indenture (herein called the "Indenture") dated as of December 5, 1996,
among the Company, the Guarantors and First Union National Bank, as trustee
(herein called the "Trustee," which term includes any successor trustee under
the Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties, obligations and immunities thereunder of the Company, the
Guarantors, the Trustee and the Holders of the Securities, and of the terms upon
which the Securities and the Guarantees are, and are to be, authenticated and
delivered.

          The Indenture contains provisions for defeasance at any time of (a)
the entire Indebtedness on the Securities and (b) certain restrictive covenants
and related Defaults and Events of Default, in each case upon compliance or
noncompliance with certain conditions set forth therein.

          The Securities shall be senior unsecured obligations of the Company,
and shall rank pari passu with all existing and future Senior Indebtedness of
the Company and senior to all Subordinated Indebtedness of the Company.  The
Securities will be effectively subordinated in right of payment to all existing
and

                                    - 37 -
<PAGE>
 
future secured indebtedness of the Company and the Company's subsidiaries.

          The Securities shall not be redeemable at the option of the Company
prior to December 1, 2000.  On or after that date, the Securities shall be
redeemable at the option of the Company, in whole or in part from time to time,
on not less than 30 nor more than 60 days' prior notice, mailed by first-class
mail to the Holders' registered addresses, in cash, in amounts of $1,000 or an
integral multiple of $1,000 at the following Redemption Prices (expressed as
percentages of the principal amount), if redeemed in the 12-month period
commencing December 1, of the years indicated below:

          Year                      Redemption
          ----                      ----------
          2000                      105.0000%
          2001                      102.5000%
          2002 and thereafter       100.0000%
 
in each case together with accrued and unpaid interest, if any, to the
Redemption Date (subject to the right of Holders of record on relevant record
dates to receive interest due on an Interest Payment Date).  If less than all of
the Securities are to be redeemed, the Trustee shall select the Securities to be
redeemed pro rata, by lot or by any other method the Trustee shall deem fair and
appropriate.

          The Securities shall not be subject to, or entitled to the benefits
of, any sinking fund.

          In addition, at any time on or prior to December 1, 1999, the Company,
at its option, may redeem up to $25,000,000 in aggregate principal amount of the
Securities at a redemption price of 110% of the principal amount thereof, plus
accrued interest, if any, to the Redemption Date, with the net proceeds of one
or more Public Equity Offerings by the Company; provided that at least
$75,000,000 aggregate principal amount of the Securities must remain outstanding
after such redemption.  The Trustee shall select the Securities or portions
thereof to be redeemed pro rata, by lot or by any other method the Trustee shall
deem fair and appropriate.

          Upon the occurrence of a Change of Control, each Holder may require
the Company to repurchase all or a portion of such Holder's Securities in an
amount of $1,000 or integral multiples of $1,000, at a purchase price in cash
equal to 101% of the principal amount thereof, together with accrued and unpaid
interest, if any, to the Change of Control Payment Date.

          Under certain circumstances, in the event the Net Proceeds received by
the Company from one or more Asset Sales, which proceeds are not applied within
180 days subsequent to the

                                    - 38 -
<PAGE>
 
consummation of the Asset Sale to repay permanently any Senior Indebtedness then
outstanding or to an investment in the Company or in one or more Restricted
Subsidiaries, equals or exceeds $5,000,000 the Company shall be required to
apply such proceeds to repurchase the Securities tendered to the Company for
purchase at a price equal to at least 100% of the principal amount thereof, plus
accrued interest, if any, to the date of purchase pursuant to an offer to
purchase made by the Company with respect to the Securities.

          In the case of any redemption or repurchase of Securities, interest
installments whose Stated Maturity is on or prior to the Redemption or
Repurchase Date shall be payable to the Holders of such Securities of record as
of the close of business on the relevant record date referred to on the face
hereof.  Securities (or portions thereof) for whose redemption or repurchase and
payment provision is made in accordance with the Indenture shall cease to bear
interest from and after the date of redemption or repurchase.

          In the event of redemption of this Security in part only, a new
Security or Securities for the unredeemed portion hereof shall be issued in the
name of the Holder hereof upon the cancellation hereof.

          If an Event of Default shall occur and be continuing, the principal
amount of all the Securities may be declared due and payable in the manner and
with the effect provided in the Indenture.

          The Indenture permits, with certain exceptions (including certain
amendments permitted without the consent of any Holders) as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the Guarantors and the rights of the Holders under the Indenture and
the Guarantees at any time by the Company, the Guarantors and the Trustee with
the consent of the Holders of a majority in aggregate principal amount of the
Securities at the time Outstanding.  The Indenture also contains provisions
permitting the Holders of specified percentages in aggregate principal amount of
the Securities at the time Outstanding, on behalf of the Holders of all the
Securities, to waive compliance by the Company and the Guarantors with certain
provisions of the Indenture and the Guarantees and certain past Defaults under
the Indenture and the Guarantees and their consequences.  Any such consent or
waiver by or on behalf of the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof whether or not notation of such consent or waiver is made upon
this Security.

                                    - 39 -
<PAGE>
 
          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, any
Guarantor or any other obligor upon the Securities (in the event such other
obligor is obligated to make payments in respect of the Securities), which is
absolute and unconditional, to pay the principal of, premium, if any, and
interest on this Security at the times, place, and rate, and in the coin or
currency, herein prescribed.

          The Securities are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, the Securities
are exchangeable for a like aggregate principal amount of Securities of a
different authorized denomination, as requested by the Holder surrendering the
same.

          No service charge shall be made for any registration of transfer or
exchange or redemption of the Securities, but the Company may require payment of
a sum sufficient to cover any tax or other governmental charge payable in
connection therewith.

          Prior to and at the time of due presentment of this Security for
registration of transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name this Security is registered as
the owner hereof for all purposes, whether or not this Security is overdue, and
neither the Company, the Trustee nor any agent shall be affected by notice to
the contrary.

          [The Company and the Guarantors have entered into an Exchange and
Registration Rights Agreement dated as of December 5, 1996 (the "Registration
Rights Agreement") with the Initial Purchasers described therein.  Pursuant to
the Registration Rights Agreement, the Company and the Guarantors have agreed,
among other things, for the benefit of the Holders that they shall, at their

best efforts to cause the Exchange Offer Registration Statement to be declared
effective under the Securities Act by the 120th day after the Issue Date and

          Section 301.   Title and Terms.
                         --------------- 

          The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is limited to $100,000,000 in
principal amount of Securities plus any Exchange Securities which may be issued
upon consummation of an Exchange Offer, except for Securities authenticated and
delivered upon registration of transfer of, or in exchange for, or in lieu of,
other Securities pursuant to Section 303, 304, 305, 306, 307, 308, 906, 1009,
1014 or 1108 hereof.

          The Securities shall be known and designated as the "10% Senior Notes
due 2003" of the Company.  The Stated Maturity of the principal amount of the
Securities shall be December 1,

                                    - 44 -
<PAGE>
 
2003, and the Securities shall each bear interest at the rate of 10% from the
Issue Date or from the most recent Interest Payment Date to which interest has
been paid, as the case may be, payable on June 1, 1997 and semiannually
thereafter on May 15 and November 15, in each year, until the principal thereof
is paid or duly provided for.  If a Registration Default shall occur, the
interest rate borne by the Securities shall be increased by 25 basis points per
annum at the beginning of each 90-day period commencing at the date of any such
Registration Default, up to a maximum aggregate increase of 100 basis points per
annum and, accordingly, the maximum interest rate on the Notes may not exceed
11%.  Upon (x) the filing or the effectiveness of the Exchange Offer
Registration Statement, (y) the consummation of the Exchange Offer or (z) the
filing or the effectiveness of the Shelf Registration Statement, as the case may
be, the interest rate borne by the Securities shall be reduced from and
including the date on which any of the events specified in clauses (x), (y) or
(z) above occur by the amount of the related increase in the interest rate set
forth above.  Notwithstanding the foregoing, the Issuers shall not be required
to pay such additional interest with respect to the Securities held by a Holder
if the applicable Registration Default arises from the failure of the Issuers to
file, or cause to become effective, a Shelf Registration Statement within the
specified time periods by reason of the failure of such Holder to provide such
information as (i) the Company may reasonably request, with reasonable prior
written notice, for use in the Shelf Registration Statement or any prospectus
included therein to the extent the Company reasonably determines that such
information is required to be included therein by applicable law, (ii) the
National Association of Securities Dealers, Inc. or the Commission may request
in connection with such Shelf Registration Statement or (iii) is required to
comply with the agreements of such Holder contained in the penultimate paragraph
of Section 5 of the Registration Rights Agreement to the extent compliance
thereof is necessary for the Shelf Registration Statement to be declared
effective.

          The principal and interest on the U.S. Global Security shall be
payable to the Depositary or its nominee, as the case may be, as the sole
registered owner and the sole Holder of the U.S. Global Security represented
thereby.  The principal of, premium, if any, and interest on the Securities
shall be payable at the office or agency of the Company maintained for such
purpose; provided, however, that at the option of the Company interest may be
         --------  -------                                                   
paid by check mailed to addresses of the Persons entitled thereto as such
addresses shall appear on the Security Register.

          The Securities shall be redeemable as provided in Article Eleven.

                                    - 45 -

          At the election of the Company, the entire Indebtedness on the
Securities or certain of the Company's obligations and covenants and certain
Events of Default thereunder may be defeased as provided in Article Four.

                         ------------- 

          The Securities shall be issuable only in registered form without
coupons and only in denominations of $1,000 and any integral multiple thereof.

          Section 303.   Execution, Authentication, Delivery and Dating.
                         ---------------------------------------------- 

          The Securities shall be executed on behalf of the Company by one of
its Chairman of the Board, its President or one of its Vice Presidents under its
corporate seal reproduced thereon and attested by its Secretary or one of its
Assistant Secretaries.

          Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices on the date of such Securities.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as
provided in this Indenture and not otherwise.

          Upon a Company Order, the Trustee shall authenticate and deliver an
additional series of notes in an aggregate principal amount not to exceed
$100,000,000 for issuance in exchange for all or a portion of the Initial
Securities previously issued and surrendered for cancellation pursuant to an
exchange offer registered under the Securities Act, in accordance with the
Registration Rights Agreement.  The Exchange Notes may have such distinctive
series designation and such changes in the form thereof as are specified in the
Company Order referred to in the preceding sentence, and shall be guaranteed by
the Guarantors on substantially identical terms as the Initial Securities.

          Each Security shall be dated the date of its authentication.

                                    - 46 -
<PAGE>
 
          No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein duly
executed by the Trustee by manual signature of an authorized signatory, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.

          In case the Company or any Guarantor, pursuant to Article Eight, shall
be consolidated, merged with or into any other Person or shall sell, assign,
convey, transfer or lease substantially all of its properties and assets to any
Person, and the successor Person resulting from such consolidation, or surviving
such merger, or into which the Company or such Guarantor shall have been merged,
or the Person which shall have received a sale, assignment, conveyance, transfer
or lease as aforesaid, shall have executed an indenture supplemental hereto with
the Trustee pursuant to Article Eight, any of the Securities authenticated or
delivered prior to such consolidation, merger, sale, assignment, conveyance,
transfer or lease may, from time to time, at the request of the successor
Person, be exchanged for other Securities executed in the name of the successor
Person with such changes in phraseology and form as may be appropriate, but
otherwise in substance of like tenor as the Securities surrendered for such
exchange and of like principal amount; and the Trustee, upon Company Request of
the successor Person, shall authenticate and deliver Securities as specified in
such request for the purpose of such exchange.  If Securities shall at any time
be authenticated and delivered in any new name of a successor Person pursuant to
this Section in exchange or substitution for or upon registration of transfer of
any Securities, such successor Person, at the option of the Holders but without
expense to them, shall provide for the exchange of all Securities at the time
Outstanding for Securities authenticated and delivered in such new name.

          The Trustee (at the expense of the Company) may appoint an
authenticating agent acceptable to the Company to authenticate Securities on
behalf of the Trustee.  Unless limited by the terms of such appointment, an
authenticating agent may authenticate Securities whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent.  An authenticating agent has the same rights as
any Security Registrar or Paying Agent to deal with the Company and its
Affiliates.

          Section 304.   Temporary Securities.
                         -------------------- 

          Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed,

                                    - 47 -
<PAGE>
 
lithographed, typewritten or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities.

          After the preparation of definitive Securities, the temporary
Securities shall be exchangeable for definitive Securities upon surrender of the
temporary Securities at the office or agency of the Company designated for such
purpose pursuant to Section 1002 hereof, without charge to the Holder.  Upon
surrender for cancellation of any one or more temporary Securities the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of authorized
denominations.  Until so exchanged the temporary Securities shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities.

          Section 305.   Registration of Transfer and Exchange.
                         ------------------------------------- 

          All provisions of this Section 305 shall be subject to Section 307
hereof.

          The Company shall cause to be kept at the Corporate Trust Office of
the Trustee, or such other office as the Trustee may designate, a register (the
register maintained in such office and in any other office or agency designated
pursuant to Section 1002 hereof being herein sometimes referred to as the
"Security Register") in which, subject to such reasonable regulations as the
Security Registrar may prescribe, the Company shall provide for the registration
of Securities and of transfers of Securities.  The Trustee or an agent thereof
or of the Company shall initially be the "Security Registrar" for the purpose of
registering Securities and transfers of Securities as herein provided.

          Upon surrender for registration of transfer of any Security at the
office or agency of the Company designated pursuant to Section 1002 hereof, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series of any authorized denomination or denominations, of a like
aggregate principal amount.

          Any Holder of the U.S. Global Security shall, by acceptance of such
U.S. Global Security, agree that transfers of beneficial interests in such U.S.
Global Security may be effected only through a book-entry system maintained by
the Holder of such U.S. Global Security (or its agent), and that ownership of a

                                    - 48 -
<PAGE>
 
beneficial interest in the Security shall be required to be reflected in a book
entry.

          At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denomination or denominations (including an
exchange of Initial Securities for Exchange Notes), of a like aggregate
principal amount, upon surrender of the Securities to be exchanged at such
office or agency.  Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities of the same series which the Holder making the exchange is entitled
to receive; provided that no exchanges of Initial Securities for Exchange Notes
shall occur until a Registration Statement shall have been declared effective by
the Commission and that any Initial Securities that are exchanged for Exchange
Notes shall be canceled by the Trustee.

          All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
Indebtedness, and entitled to the same benefits under this Indenture, as the
Securities surrendered upon such registration of transfer or exchange.

          Every Security presented or surrendered for registration of transfer,
or for exchange or redemption shall (if so required by the Company or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer
in form satisfactory to the Company and the Security Registrar, duly executed by
the Holder thereof or his attorney duly authorized in writing.

          No service charge shall be made to a Holder for any registration of
transfer or exchange or redemption of Securities, but the Company may require
payment of a sum sufficient to pay all documentary, stamp or similar issue or
transfer taxes or other governmental charges that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges of Initial Securities for Exchange Notes and exchanges pursuant to
Section 303, 304, 305, 306, 307, 308, 906, 1009, 1014 or 1108 hereof not
involving any transfer.

          The Company shall not be required (a) to issue, register the transfer
of or exchange any Security during a period beginning at the opening of business
(i) 15 days before the date of selection of Securities for redemption under
Section 1104 hereof and ending at the close of business on the day of such
mailing or (ii) 15 days before an Interest Payment Date and ending on the close
of business on the Interest Payment Date, or (b) to register the transfer of or
exchange any Security so selected for redemption in whole or in part, except the
unredeemed portion of Securities being redeemed in part.

          Section 306.  Book-Entry Provisions for U.S. Global Security.
                        ---------------------------------------------- 

          All provisions of this Section 306 shall be subject to Section 307
hereof.

          (a)  The U.S. Global Security initially shall (i) be registered in the
name of the Depositary for such U.S. Global Security or the nominee of such
Depositary, (ii) be delivered to the Trustee as custodian for such Depositary
and (iii) bear legends as set forth in Section 202 hereof.

          Members of, or participants in, the Depositary ("Agent Members") shall
have no rights under this Indenture with respect to any U.S. Global Security
held on their behalf by the Depositary, or the Trustee as its custodian, or
under the U.S. Global Security, and the Depositary may be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the absolute
owner of such U.S. Global Security for all purposes whatsoever.  Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Trustee or any
agent of the Company or the Trustee, from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or
impair, as between the Depositary and its Agent Members, the operation of
customary practices governing the exercise of the rights of a Holder of any
Security.

          (b)  Transfers of the U.S. Global Security shall be limited to
transfers of such U.S. Global Security in whole, but not in part, to the
Depositary, its successors or their respective nominees.  Interests of
beneficial owners in the U.S. Global Security may be transferred in accordance
with the rules and procedures of the Depositary and the provisions of Section
307 hereof.  Beneficial owners may obtain Physical Securities in exchange for
their beneficial interests in the U.S. Global Security upon request in
accordance with the Depositary's and the Registrar's procedures.  In addition,
Physical Securities shall be transferred to all beneficial owners in exchange
for their beneficial interests in the U.S. Global Security if (i) the Depositary
notifies the Company that it is unwilling or unable to continue as Depositary
for the U.S. Global Security or ceases to be a "clearing agency" registered
under the Exchange Act and a successor depositary is not appointed by the
Company within 90 days of such notice or (ii) an Event of Default has occurred
and is continuing and the Security Registrar, the Depositary and the Company
have, through Agent Members, received a request in writing from Holders of
beneficial interests in the U.S. Global Note with interests aggregating not less
than a majority that the continuation of a book-entry system through the
Depositary or its successors is no longer in their best interest.

<PAGE>
 
          (c)  In connection with any transfer of a portion of the beneficial
interest in the U.S. Global Security to beneficial owners pursuant to Subsection
(b) of this Section, the Security Registrar shall reflect on its books and
records the date and a decrease in the principal amount of the U.S. Global
Security in an amount equal to the principal amount of the beneficial interest
in the U.S. Global Security to be transferred, and the Company shall execute,
and the Trustee shall authenticate and deliver, one or more Physical Securities
of like tenor and amount.

          (d)  In connection with the transfer of the entire U.S. Global
Security to beneficial owners pursuant to Subsection (b) of this Section, the
U.S. Global Security shall be surrendered to the Trustee for cancellation, and
the Company shall execute, and the Trustee shall authenticate and deliver, to
each beneficial owner identified by the Depositary in exchange for its
beneficial interest in the U.S. Global Security, an equal aggregate principal
amount of Physical Securities of authorized denominations.

          (e)  Any Physical Security delivered in exchange for an interest in
the U.S. Global Security pursuant to Subsection (b) or Subsection (c) of this
Section shall, except as otherwise provided by Subsection (a)(i)(x) and
Subsection (d) of Section 307 hereof, bear the applicable legend regarding
transfer restrictions applicable to the Physical Security set forth in Section
202 hereof.

          (f)  The registered Holder of the U.S. Global Security may grant
proxies and otherwise authorize any person, including Agent Members and persons
that may hold interests through Agent Members, to take any action which a Holder
is entitled to take under this Indenture or the Securities.

          Section 307.   Special Transfer Provisions.
                         --------------------------- 

          Unless and until an Initial Security is exchanged for an Exchange Note

Securities and an Initial Security is sold pursuant to the plan of distribution
thereunder, the following provisions shall apply:

          bears the Private Placement Legend, if (x) the requested transfer is

          proposed transferee has delivered to the Security Registrar a letter
          containing certain representations and agreements substantially in the
          form of Exhibit A hereto.
                  ---------        

               (ii)  If the proposed transferor is an Agent Member holding a

          Security Registrar of (x) the documents, if any, required by paragraph
          (i) and (y) instructions given in accordance with the Depositary's and
          the Security Registrar's procedures, the Security Registrar shall
          reflect on its books and records the date and a decrease in the
          principal amount of the U.S. Global Security in an amount equal to the
          principal amount of the beneficial interest in the U.S. Global
          Security to be transferred, and the Company shall execute, and the
          Trustee shall authenticate and deliver, one or more Physical
          Securities of like tenor and amount.

          (b)  Transfers to QIBs.  The following provisions shall apply with

     respect to the registration of any proposed transfer of a Security to a
     QIB:

               (i)  If the Security to be transferred consists of Physical
          Securities, the Security Registrar shall register the transfer if such
          transfer is being made by a proposed transferor who has checked the
          box provided for on the form of Security stating, or has otherwise
          advised the Company and the Security Registrar in writing, that the
          sale has been made in compliance with the provisions of Rule 144A to a
          transferee who has signed the certification provided for on the form

          Security Registrar in writing, that it is purchasing the Security for
          its own account or an account with respect to which it exercises sole
          investment discretion and that it and any such account is a QIB within
          the meaning of Rule 144A, and is aware that the sale to it is being
          made in reliance on Rule 144A and acknowledges that it has received
          such information regarding the Company as it has requested pursuant to
          Rule 144A or has determined not to request such information and that
          it is aware that the transferor is relying upon its foregoing
          representations in order to claim the exemption from registration
          provided by Rule 144A.

               (ii)  If the proposed transferee is an Agent Member, and the
          Security to be transferred consists of Physical Securities, upon
          receipt by the Security Registrar of instructions given in accordance
          with the Depositary's and the Security Registrar's procedures, the

          therewith the Company shall have received an Opinion of Counsel, at
          its expense, in form and substance reasonably satisfactory to the
          Company, to the effect that such Security to be issued upon such
          transfer or exchange may be so issued without such legend because (A)
          such Security is being exchanged for an Exchange Note, (B) such
          Security shall have been registered under the Securities Act, the
          registration statement in connection therewith shall have been

          Officers' Certificate directing the Trustee and the Security Registrar
          to deliver an unlegended Security in connection with such transfer or

               (ii)  the transfer or exchange of a Security not bearing such
          legend.

          (d)  General.
               ------- 

               (i)  By its acceptance of any Security bearing the Private
          Placement Legend, each Holder of such a Security acknowledges the
          restrictions on transfer of such Security set forth in this Indenture
          and in the Private Placement Legend and agrees that it shall

          for another legended Security, the Company shall have received an
          opinion of counsel of the Holder (which may include in-house counsel
          of such Holder experienced in matters of Federal securities law), at
          its expense, in form and substance reasonably satisfactory to the
          Company to the effect that such transfer does not require registration

          Trustee and the Security Registrar a copy of such opinion of counsel
          of the Holder together with an Officers' Certificate directing the

          Section 308.   Mutilated, Destroyed, Lost and Stolen Securities.
                         ------------------------------------------------ 

          If (a) any mutilated Security is surrendered to the Trustee, or (b)
the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and there is delivered to the
Company, each Guarantor and the Trustee, such security or indemnity, in each
case, as may be required by them to save each of them harmless, then, in the
absence of notice to the Company, any Guarantor or the Trustee that such
Security has been acquired by a bona fide purchaser, the Company shall execute
and upon its written request the Trustee shall authenticate and deliver, in
exchange for any such mutilated Security or in lieu of any such destroyed, lost
or stolen Security, a replacement Security of like tenor and principal amount,
bearing a number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a replacement Security, pay such Security.

                                    - 54 -

          Upon the issuance of any replacement Securities under this Section,
the Company may require the payment of a sum sufficient to pay all documentary,
stamp or similar issue or transfer taxes or other governmental charges that may

expenses of the Trustee) connected therewith.

any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company and the Guarantors, whether or not the
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder.

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

          Section 309.   Payment of Interest; Interest Rights Preserved.
                         ----------------------------------------------

duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security is registered at the close of business on the Regular
Record Date for such interest.

          Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date and interest on such
defaulted interest at the then applicable interest rate borne by the Securities,
to the extent lawful (such defaulted interest and interest thereon herein
collectively called "Defaulted Interest") shall forthwith cease to be payable to
the Holder on the Regular Record Date; and such Defaulted Interest may be paid
by the Company, at its election in each case, as provided in Subsection (a) or
(b) below:

          (a)  the Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Securities are registered at the close of
     business on a Special Record Date for the payment of such Defaulted
     Interest, which shall be fixed in the following manner.  The Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each Security and the date (not less than 30 days after such
     notice) of the proposed payment, and at the same time the Company shall
     deposit with the Trustee an amount of money equal to the aggregate amount
     proposed to be paid in respect of such Defaulted Interest or shall make
     arrangements satisfactory

                                    - 55 -

     to the Trustee for such deposit prior to the date of the proposed payment,
     such money when deposited to be held in trust for the benefit of the
     Persons entitled to such Defaulted Interest as in this Subsection provided.
     Thereupon the Trustee shall fix a Special Record Date for the payment of
     such Defaulted Interest which shall be not more than 15 days and not less
     than 10 days prior to the date of the proposed payment and not less than 10
     days after the receipt by the Trustee of the notice of the proposed
     payment.  The Trustee shall promptly notify the Company in writing of such
     Special Record Date.  In the name and at the expense of the Company, the
     Trustee shall cause notice of the proposed payment of such Defaulted
     Interest and the Special Record Date therefor to be mailed, first-class
     postage prepaid, to each Holder at his address as it appears in the
     Security Register, not less than 10 days prior to such Special Record Date.
     Notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor having been so mailed, such Defaulted Interest shall
     be paid to the Persons in whose names the Securities are registered on such
     Special Record Date and shall no longer be payable pursuant to the
     following Subsection (b).

          (b)  The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Securities may be listed, and upon such
     notice as may be required by such exchange, if, after written notice given
     by the Company to the Trustee of the proposed payment pursuant to this
     Subsection, such payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security (including any Exchange Security issued in
exchange for an Initial Security) shall carry the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Security.

                         -------------------------------------------------
Defeasance.
- ---------- 

          The Company may, at its option by Board Resolution, at any time, with
respect to the Securities, elect to have either Section 402 or Section 403
hereof be applied to all of the Outstanding Securities (the "Defeased
Securities"), upon compliance with the conditions set forth below in this
Article Four.

          Section 402.   Defeasance and Discharge.
                         ------------------------ 

          Upon the Company's exercise under Section 401 hereof of the option
applicable to this Section 402, the Company, each of the Guarantors and any
other obligor upon the Securities, if any, shall be deemed to have been
discharged from its obligations with respect to the Defeased Securities on the
date the conditions set forth below are satisfied (hereinafter, "defeasance").
For this purpose, such defeasance means that the Company shall be deemed to have
paid and discharged the entire Indebtedness represented by the Defeased
Securities, which shall thereafter be deemed to be "Outstanding" only for the
purposes of Section 405 hereof and the other Section of this Indenture referred
to in (a) and (b) below, and to have satisfied all its other obligations under
such Securities and this Indenture insofar as such Securities are concerned (and
the Trustee, at the expense of the Company, and, upon written request, shall
execute proper instruments acknowledging the same), except for the following
which shall survive until otherwise terminated or discharged hereunder:  (a) the
rights of Holders of Defeased Securities to receive, solely from the trust fund
described in Section 404 hereof and as more fully set forth in such Section,
payments in respect of the principal of, premium if any, and interest on such
Securities when such payments are due, (b) the Company's obligations with
respect to such Defeased Securities under Sections 304, 305, 308, 1002 and 1018
hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee
hereunder including, without limitation, the Trustee's rights under Section 606
hereof and the Company's obligations in connection therewith, and (d) this
Article Four.  Subject to compliance with this Article Four, the Company may
exercise its option under this Section 402 notwithstanding the prior exercise of
its option under Section 403 hereof with respect to the Securities.

          Section 403.   Covenant Defeasance.
                         ------------------- 

          Upon the Company's exercise under Section 401 hereof of the option
applicable to this Section 403, the Company and each

                                    - 58 -
<PAGE>
 
Guarantor shall be released from its obligations under any covenant or provision
contained or referred to in Sections 1004, 1005, 1006, 1007, 1008, 1009, 1010,
1011, 1012, 1014, 1015, 1016, 1019 and 1020 hereof with respect to the Defeased
Securities on and after the date the conditions set forth below are satisfied
(hereinafter, "covenant defeasance"), and the Defeased Securities shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"Outstanding" for all other purposes hereunder.  For this purpose, such covenant
defeasance means that, with respect to the Defeased Securities, the Company and
each Guarantor may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such Section or Article,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such Section or Article or by reason of any reference in any such Section or
Article to any other provision herein or in any other document and such omission
to comply shall not constitute a Default or an Event of Default under Section
501(3) or (4) hereof but, except as specified above, the remainder of this
Indenture and such Defeased Securities shall be unaffected thereby.

          Section 404.   Conditions to Defeasance or Covenant Defeasance.
                         -----------------------------------------------

402 or Section 403 hereof to the Defeased Securities:

          (1)  The Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee satisfying the requirements
     of Section 608 hereof who shall agree to comply with the provisions of this
     Article Four applicable to it) as trust funds in trust for the purpose of
     making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of such Securities, (a)
     United States dollars in an amount, or (b) U.S. Government Obligations
     which through the scheduled payment of principal and interest in respect
     thereof in accordance with their terms shall provide, not later than one
     day before the due date of any payment, money in an amount, or (c) a
     combination thereof, sufficient, in the opinion of a nationally recognized
     firm of independent public accountants or a nationally recognized
     investment banking firm expressed in a written certification thereof
     delivered to the Trustee, to pay and discharge and which shall be applied
     by the Trustee (or other qualifying trustee) to pay and discharge the
     principal of, premium, if any, and interest on the Defeased Securities on
     the Stated Maturity of such principal or installment of principal or

                                    - 59 -
<PAGE>
 
     interest (such date being referred to as the "Defeasance Redemption Date"),
     if when exercising under Section 401 hereof either its option applicable to
     Section 402 hereof or its option applicable to Section 403 hereof, the
     Company shall have delivered to the Trustee an irrevocable notice to redeem
     all of the Outstanding Securities on the Defeasance Redemption Date);
     provided that the Trustee shall have been irrevocably instructed to apply
     such United States dollars or the proceeds of such U.S. Government
     Obligations to said payments with respect to the Securities.

          (2)  In the case of an election under Section 402 hereof, the Company
     shall have delivered to the Trustee an Opinion of Independent Counsel in
     the United States of America stating that (A) the Company has received from
     the Internal Revenue Service a ruling or (B) since the Issue Date, there
     has been a change in the applicable federal income tax law, including by
     means of a Revenue Ruling published by the Internal Revenue Service, in
     either case to the effect that, and based thereon such Opinion of
     Independent Counsel in the United States of America shall confirm that, the
     Holders of the Outstanding Securities will not recognize income, gain or
     loss for federal income tax purposes as a result of such defeasance and
     will be subject to federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such defeasance
     had not occurred.

          (3)  In the case of an election under Section 403 hereof, the Company
     shall have delivered to the Trustee an Opinion of Independent Counsel in
     the United States of America to the effect that the Holders of the
     Outstanding Securities will not recognize income, gain or loss for federal
     income tax purposes as a result of such covenant defeasance and will be
     subject to federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such covenant defeasance
     had not occurred.

          (4)  No Default or Event of Default shall have occurred and be
     continuing on the date of such deposit or insofar as Subsection 501(9) or
     (10) hereof is concerned, at any time during the period ending on the 91st
     day after the date of deposit.

          (5)  Such defeasance or covenant defeasance shall not result in a
     breach or violation of, or constitute a Default under, any material
     agreement or instrument (other than this Indenture) to which the Company or
     any Guarantor is a party or by which it is bound.

                                    - 60 -

          (6)  The Company shall have delivered to the Trustee an Opinion of
     Independent Counsel to the effect that (A) the trust funds will not be
     subject to any rights of holders of Senior Indebtedness of the Company or
     of any Guarantor and (B) after the 91st day following the deposit, the
     trust funds will not be subject to the effect of any applicable bankruptcy,
     insolvency, reorganization or similar laws affecting creditors' rights
     generally.

          (7)  The Company shall have delivered to the Trustee an Officers'
     Certificate stating that the deposit was not made by the Company with the
     intent of preferring the Holders of the Securities or any Guarantee over
     the other creditors of the Company or any Guarantor with the intent of
     defeating, hindering, delaying or defrauding creditors of the Company, any
     Guarantor or others.

          (8)  The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Independent Counsel, each stating that all
     conditions precedent provided for relating to either the defeasance under
     Section 402 hereof or the covenant defeasance under Section 403 hereof (as
     the case may be) have been complied with as contemplated by this Section
     404.

Opinions of Counsel or Opinions of Independent Counsel required to be delivered
under this Section may have qualifications customary for opinions of the type
required and counsel delivering such opinions may rely on certificates of the
Company or government or other officials customary for opinions of the type
required, including certificates certifying as to matters of fact, including
that various financial covenants have been complied with.

          Section 405.   Deposited Money and U.S. Government Obligations to Be
                         -----------------------------------------------------
Held in Trust; Other Miscellaneous Provisions.
- --------------------------------------------- 

          Subject to the provisions of the last paragraph of Section 1018
hereof, all United States dollars and U.S. Government Obligations (including the
proceeds thereof) deposited with the Trustee (or other qualifying trustee--
collectively for purposes of this Section 405, the "Trustee") pursuant to
Section 404 hereof in respect of the Defeased Securities shall be held in trust
and applied by the Trustee, in accordance with the provisions of such Securities
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities of all sums due and to become due
thereon in respect of principal, premium, if any, and interest, but such money
need not be segregated from other funds except to the extent required by law.

                                    - 61 -
<PAGE>
 
          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 404 hereof or the principal and interest received
in respect thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of the Defeased Securities.

          Anything in this Article Four to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any United States dollars or U.S. Government Obligations held by it as
provided in Section 404 hereof which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, are in excess of the amount thereof which
would then be required to be deposited to effect defeasance or covenant
defeasance.

          Section 406.   Reinstatement.
                         ------------- 

          If the Trustee or Paying Agent is unable to apply any United States
dollars or U.S. Government Obligations in accordance with Section 402 or 403
hereof, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's and each Guarantor's obligations under this
Indenture and the Securities (including, without limitation, the provisions of
Article Thirteen hereof) shall be revived and reinstated as though no deposit
had occurred pursuant to Section 402 or 403 hereof, as the case may be, until
such time as the Trustee or Paying Agent is permitted to apply all such United
States dollars or U.S. Government Obligations in accordance with Section 402 or
403 hereof, as the case may be; provided, however, that if the Company makes any
                                --------  -------                               
payment to the Trustee or Paying Agent of principal of, premium, if any, or
interest on any Security following the reinstatement of its obligations, the
Trustee or Paying Agent shall promptly pay any such amount to the Holders of the
Securities and the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money held by the Trustee or
Paying Agent.

          Section 407.   Repayment of the Company.
                         ------------------------ 

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of, premium, if any,
or interest on any Security and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Company on its written request or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Security shall
thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all

                                    - 62 -
<PAGE>
 
liability of the Trustee or such Paying Agent with respect to such trust money,
shall thereupon cease, provided, however, that the Trustee or such Paying Agent,
                       --------  -------                                        
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in the New York Times and The Wall Street
Journal (national edition), notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than thirty (30) days
from the date of such notification or publication, any unclaimed balance of such
money then remaining shall promptly be repaid to the Company.

          Section 501.   Events of Default.
                         ----------------- 

          An "Event of Default" shall occur if:

          (1)  there shall be a default in the payment of interest on any
     Security when the same becomes due and payable and the Default continues
     for a period of thirty (30) days;

          (2)  there shall be a default in the payment of the principal of, or
     premium with respect to, any Security when the same becomes due and
     payable, at maturity, upon redemption, in connection with a Change of
     Control, an Asset Sale or otherwise;

          (3)  the Company or any Guarantor fails to observe or perform any
     covenant, condition or agreement on the part of the Company or such
     Guarantor to be observed or performed pursuant to Section 1006, 1008, 1009,
     1010, 1012, 1014, 1019, 1020 or Article Eight hereof;

          (4)  the Company or any Guarantor fails to observe or perform any
     other covenant, condition or agreement in this Indenture or the Securities
     and such failure continues for the period and after the notice specified
     below;

          (5)  the Company denies or disaffirms its obligations under this
     Indenture or the Securities;

          (6) a Guarantor denies or disaffirms its obligations under its
     Guarantee, or any Guarantee for any reason ceases to be, or is asserted in

     and enforceable in accordance with its terms, except to the extent
     contemplated by this Indenture and any such Guarantee;

                                    - 63 -
<PAGE>
 
          (7)  a default occurs under any Indebtedness of the Company or any of
     its Subsidiaries (other than the Securities or the Guarantees), whether
     such Indebtedness now exists or is created after the Closing Date if either
     (A) such default results from the failure to pay the final scheduled
     principal installment in respect of any such Indebtedness on the stated
     maturity date thereof (after giving effect to any grace period) or (B) as a
     result of such default, the maturity of such Indebtedness has been
     accelerated prior to its express maturity and, in each case, the principal
     amount of such Indebtedness, together with the principal amount of all
     other Indebtedness with respect to which the principal amount remains
     unpaid at its final maturity (after giving effect to any grace period in
     respect of such final scheduled principal installment) or the maturity of
     which has been so accelerated, aggregates $5,000,000 or more;

          (8)  a final judgment or final judgments for the payment of money are
     entered by a court or courts of competent jurisdiction against the Company
     or any of its Restricted Subsidiaries and such judgment or judgments remain
     undischarged, unbonded or unstayed for a period of sixty (60) days,
     provided that the aggregate of all such judgments (other than any judgment
     as to which and only to the extent, a reputable insurance company has
     acknowledged coverage of such claim in writing) exceeds $5,000,000;

          (9)  the Company, any Guarantor or any other Restricted Subsidiary
     pursuant to or within the meaning of any Bankruptcy Law:

               (a)  commences a voluntary case,

               (b)  consents to the entry of an order for relief against it in
          an involuntary case in which it is a debtor,

               (c)  consents to the appointment of a Custodian of it or for all
          or substantially all of its property,

               (d)  makes a general assignment for the benefit of its creditors,
          or

               (e) admits in writing its inability to pay debts as the same
          become due; or

                                    - 64 -
<PAGE>
 
          (10)  a court of competent jurisdiction enters an order or decree
     under any Bankruptcy Law that:

               (a) is for relief against the Company, any Guarantor or any other
          Restricted Subsidiary in an involuntary case in which it is a debtor,

               (b) appoints a Custodian of the Company, any Guarantor or any
          other Restricted Subsidiary or for all or substantially all of their
          property,

               (c) orders the liquidation of the Company, any Guarantor or any
          other Restricted Subsidiary,

     and the order or decree remains unstayed and in effect for sixty (60) days.

          The term "Custodian" means any receiver, trustee, assignee, liquidator
or similar official under any Bankruptcy Law.

          A Default under clause (4) is not an Event of Default until the
Trustee notifies the Company, or the Holders of at least 25% in principal amount
of the Securities then Outstanding notify the Company and the Trustee, of the
Default and the Company does not cure the Default within sixty (60) days after
receipt of such notice.  The notice must specify the Default, demand that it be
remedied and state that the notice is a "Notice of Default."

          The failure to make any payment on the Securities when due shall,
after the expiration date of any applicable grace period, constitute an Event of
Default under this Indenture.

          Section 502.   Acceleration.
                         ------------ 

          If an Event of Default (other than an Event of Default specified in
clauses (9) and (10) of Section 501 hereof) occurs and is continuing, the
Trustee by notice to the Company, or the Holders of at least 25% in principal
amount of the Securities then Outstanding by written notice to the Company and
the Trustee, may declare the unpaid principal of and any accrued interest on all
the Securities to be due and payable.  Upon such declaration the principal and
interest shall be due and payable immediately.  If an Event of Default specified
in clause (9) or (10) of Section 501 hereof occurs, such an amount shall ipso
                                                                         ----
facto become and be immediately due and payable without any declaration or other
- -----                                                                           
act on the part of the Trustee or any Holder.  The Holders of a majority (or, in
the case of the failure to make a Change of Control Offer pursuant to Section
1014 hereof, two-thirds) in principal amount of Securities then Outstanding by
written notice to the Trustee may

                                    - 65 -
<PAGE>
 
rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if:

          (a) the Company has paid or deposited with the Trustee a sum
     sufficient to pay

               (i)  all sums paid or advanced by the Trustee under this
          Indenture and the reasonable compensation, expenses, disbursements and
          advances of the Trustee, its agents and counsel,

              (ii)  all overdue interest on all Securities,

             (iii)  the principal of and premium, if any, on any Securities
          which have become due otherwise than by such declaration of
          acceleration and interest thereon at a rate borne by the Securities,
          and

              (iv)  to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate borne by the Securities;
          and

          (b) all Events of Default, other than the non-payment of principal of
     the Securities which have become due solely by such declaration of
     acceleration, have been cured or waived as provided in Section 504 hereof.
     No such rescission shall affect any subsequent Default or impair any right
     consequent thereon provided in Section 504 hereof.

          Section 503.   Other Remedies.
                         -------------- 

          If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy (under this Indenture or otherwise) to collect the
payment of principal, premium, if any, or interest on the Securities or to
enforce the performance of any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default.

          No right or remedy herein conferred upon or reserved to the Trustee or
to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall

                                    - 66 -
<PAGE>
 
not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

          Section 504.   Waiver of Past Defaults.
                         ----------------------- 

          Holders of a majority (or, in the case of the failure by the Company
to make a Change of Control Offer pursuant to Section 1014 hereof, two-thirds)
in aggregate principal amount of the Securities then Outstanding by notice to
the Trustee may waive an existing Default or Event of Default and its conse
quences, except a continuing Default or Event of Default in the payment of the
principal of or interest on any Security held by a non-consenting Holder.  Upon
any such waiver, such Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

          Section 505.   Control by Majority.
                         ------------------- 

          The Holders of a majority in principal amount of the Securities then
Outstanding may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power
conferred on it.  However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture, that the Trustee determines may be unduly
prejudicial to the rights of other Holders, or that may involve the Trustee in
personal liability.

          Section 506.   Limitation on Suits.
                         ------------------- 

          A Holder may pursue a remedy with respect to this Indenture or the
Securities only if:

          (1)  the Holder gives to the Trustee written notice of a continuing
     Event of Default;

          (2)  the Holders of at least 25% in principal amount of the Securities
     then Outstanding make a written request to the Trustee to pursue the
     remedy;

          (3)  such Holder or Holders offer and, if requested, provide to the
     Trustee indemnity satisfactory to the Trustee against any loss, liability
     or expense;

          (4)  the Trustee does not comply with the request within sixty (60)
     days after receipt of the request and the offer and, if requested, the
     provision of the indemnity; and

          (5)  during such sixty (60) day period the Holders of a majority in
     principal amount of the Securities then

                                    - 67 -

to obtain a preference or priority over another Holder.

          Section 507.   Rights of Holders to Receive Payment.
                         ------------------------------------ 

          Notwithstanding any other provision of this Indenture, but subject to
Article Thirteen the right of any Holder of a Security to receive payment of
principal, premium, if any, and interest on the Security, on or after the
respective due dates expressed in the Security (or, in the case of redemption or
repurchase, on the Redemption Date or repurchase date), or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of the Holder, subject to Article
Thirteen.

          Section 508.   Collection Suit by Trustee.
                         -------------------------- 

          If an Event of Default specified in Section 501(1) or (2) hereof
occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company or any Guarantor
for the whole amount of principal, premium, if any, and interest remaining
unpaid on the Securities and interest on overdue principal and, to the extent
lawful, premium and interest and such further amount as shall be sufficient to
cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, subject to Article Thirteen.

          If the Company or any Guarantor, as the case may be, fails to pay such
amounts forthwith upon such demand, the Trustee, in its own name and as trustee
of an express trust, may institute a judicial proceeding for the collection of
the sums so due and unpaid and may prosecute such proceeding to judgment or
final decree, and may enforce the same against the Company or any Guarantor or
any other obligor upon the Securities and collect the moneys adjudged or decreed
to be payable in the manner provided by law out of the property of the Company
or any Guarantor or any other obligor upon the Securities, wherever situated.

          If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders under this Indenture or the Guarantees by such appropriate private or
judicial proceedings as the Trustee shall deem most effectual to protect and
enforce such rights, including, seeking recourse against any Guarantor pursuant
to the terms of any Guarantee, whether for the specific

                                    - 68 -
<PAGE>
 
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein or therein, or to enforce any other proper
remedy, including, without limitation, seeking recourse against any Guarantor
pursuant to the terms of a Guarantee, or to enforce any other proper remedy,
subject however to Section 505 hereof.

          Section 509.   Trustee May File Proofs of Claim.
                         -------------------------------- 

          The Trustee is authorized to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims
of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders allowed in any judicial proceedings relative to the Company or any
Guarantor or any other obligor upon the Securities, their creditors or their
property and shall be entitled and empowered, subject to Article Thirteen, to
collect, receive and distribute any money or other property payable or
deliverable on any such claims and any Custodian in any such judicial proceeding
is hereby authorized by each Holder to make such payments to the Trustee, and in
the event that the Trustee shall consent to the making of such payments directly
to the Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 606 hereof.  To
the extent that the payment of any such compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 606 hereof out of the estate in any such proceeding
shall be denied for any reason, payment of the same shall be secured by a Lien
on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties which the Holders of the Securities may be
entitled to receive in such proceeding whether in liquidation or under any plan
of reorganization or arrangement or otherwise.  Nothing herein contained shall
be deemed to authorize the Trustee to authorize or consent to or accept or adopt
on behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

     liabilities incurred, and all

     advances made, by the Trustee and the costs and expenses of collection;

          Second:  subject to Article Thirteen, to Holders for amounts due and

     ratably, without preference or priority of any kind, according to the
     amounts due and payable on the Securities for principal, premium, if any,
     and interest, respectively;

          Third:  subject to Article Thirteen, without duplication, to Holders
     for any other Indenture Obligations owing to the Holders under this
     Indenture or the Securities; and

          Fourth:  subject to Article Thirteen, to the Company or to such party
     as a court of competent jurisdiction shall direct.

          The Trustee may fix a record date and payment date for any payment to
Holders.

                         --------------------- 

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.

any Holder for the enforcement of the payment of the principal of, premium, if
any, or interest on any Security on or after the respective Stated Maturities
expressed in such Security (or, in the case of redemption or repurchase, on or
after the Redemption Date or repurchase date).

                         ----------------------------------------

          Each of the Company and any Guarantor covenants (to the extent that it
may lawfully do so) that it shall not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law or any usury or other law wherever enacted, now or at any time
hereafter in force, which would prohibit or forgive the Company or any Guarantor
from paying all or any portion of the principal of, premium, if any, or interest
on the Securities contemplated

of any power herein granted to the Trustee, but shall suffer and permit the
execution of every such power as though no such law had been enacted.

          The Company covenants and agrees to pay to the Trustee from time to
time, and the Trustee shall be entitled to, reasonable compensation for all
services rendered by it hereunder, subject to the terms of any written agreement
by the Trustee concerning the amount of its compensation (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust) and the Company covenants and agrees to pay or reimburse the
Trustee and each predecessor Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by or on behalf of it in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all agents and other persons not regularly in its employ) except any such
expense, disbursement or advance as may arise from its negligence or bad faith.
The Company also covenants to indemnify the Trustee and each predecessor Trustee
for, and to hold it harmless against, any loss, liability, tax, assessment or
other governmental charge (other than taxes applicable to the Trustee's
compensation hereunder) or expense incurred without gross negligence or bad
faith on such Trustee's part, arising out of or in connection with the

survive the satisfaction and discharge of this Indenture, or the resignation or

Trustee shall have a Lien prior to the Securities on all money or property held

property held in trust to pay principal of or interest on particular Securities.

with an Event of Default specified in Section 501(9) or 501(10) hereof the
expenses and the compensation for the services shall be preferred over the
status of Holders in any proceeding under any Bankruptcy Law and are intended to

reasonably acceptable to the Company to conduct any activities which the Trustee
may be required under this Indenture to conduct in The City of Philadelphia.  If

be its combined capital and surplus as set forth in its most recent report of
condition so published.  If at any time the Trustee shall cease to be eligible
in accordance with the provisions of this Section, the Trustee shall resign

          (a)  No resignation or removal of the Trustee and no appointment of a
successor trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor trustee under Section 610 hereof.

          (b)  The Trustee, or any trustee or trustees hereafter appointed, may
at any time resign by giving written notice thereof to the Company.  Upon
receiving such notice of resignation, the Company shall promptly appoint a
successor trustee by written instrument executed by authority of the Board of
Directors, a copy of which shall be delivered to the resigning Trustee and a
copy to the successor trustee.  If an instrument of acceptance by a successor
trustee shall not have been delivered to the Trustee within thirty (30) days
after the giving of such notice of resignation, the resigning Trustee may, or
any Holder who has been a bona fide Holder of a Security for at least


                                    - 75 -

six months may, on behalf of himself and all others similarly situated, petition

Such court may thereupon, after such notice, if any, as it may deem proper,
appoint a successor trustee.

          (c)  The Trustee may be removed at any time by an Act of the Holders
of not less than a majority in aggregate principal amount of the Outstanding
Securities, delivered to the Trustee and to the Company.

               (1)  the Trustee shall fail to comply with the provisions of
          Trust Indenture Act Section 310(b) after written request therefor by
          the Company or by any Holder who has been a bona fide Holder of a
          Security for at least six months, or

               (2)  the Trustee shall cease to be eligible under Section 608
          hereof and shall fail to resign after written request therefor by the
          Company or by any Holder who has been a bona fide Holder of a Security
          for at least six months, or

               (3)  the Trustee shall become incapable of acting or shall be
          adjudged a bankrupt or insolvent, or a receiver of the Trustee or of
          its property shall be appointed or any public officer shall take
          charge or control of the Trustee or of its property or affairs for the
          purpose of rehabilitation, conservation or liquidation,

then, in any case, (i) the Company by a Board Resolution may remove the Trustee,
or (ii) subject to Section 511 hereof, the Holder of any Security who has been a
bona fide Holder of a Security for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor trustee.  Such
court may thereupon, after such notice, if any, as it may deem proper and
prescribe, remove the Trustee and appoint a successor trustee.

          (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor trustee.  If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor trustee so
appointed shall, forthwith upon its


                                    - 76 -
<PAGE>
 
acceptance of such appointment, become the successor trustee and supersede the
successor trustee appointed by the Company.  If no successor trustee shall have
been so appointed by the Company or the Holders of the Securities and accepted
appointment in the manner hereinafter provided, the Holder of any Security who
has been a bona fide Holder for at least six months may, subject to Section 511
hereof, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the appointment of a successor trustee.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee and each appointment of a successor trustee by mailing written
notice of such event by first-class mail, postage prepaid, to the Holders of
Securities as their names and addresses appear in the Security Register.  Each
notice shall include the name of the successor trustee and the address of its
Corporate Trust Office or agent hereunder.

          Every successor trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee as if originally named as Trustee hereunder;
but, nevertheless, on the written request of the Company or the successor
trustee, upon payment of its charges then unpaid, such retiring Trustee shall,
pay over to the successor trustee all moneys at the time held by it hereunder
and shall execute and deliver an instrument transferring to such successor
trustee all such rights, powers, duties and obligations.  Upon request of any
such successor trustee, the Company shall execute any and all instruments for
more fully and certainly vesting in and confirming to such successor trustee all
such rights and powers.  Any Trustee ceasing to act shall, nevertheless, retain
a prior claim upon all property or funds held or collected by such Trustee or
such successor trustee to secure any amounts then due such Trustee pursuant to
the provisions of Section 606 hereof.

          No successor trustee with respect to the Securities shall accept
appointment as provided in this Section 610 unless at the time of such
acceptance such successor trustee shall be eligible to act as trustee under the
provisions of Trust Indenture Act Section 310(a) and this Article Six and shall
have a combined capital and surplus of at least $50,000,000 or which shall be a
wholly owned subsidiary of a company that has a combined capital and surplus of
at least $50,000,000 and have a Corporate Trust Office or an agent selected in
accordance with Section 608 hereof.

          Upon acceptance of appointment by any successor trustee as provided in
this Section 610, the Company shall give notice thereof to the Holders of the
Securities, by mailing such notice to such Holders at their addresses as they
shall appear on the Security Register.  If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the preceding sentence may be combined with the notice called for by Section
609 hereof.  If the Company fails to give such notice within ten (10) days after
acceptance of appointment by the successor trustee, the successor trustee shall
cause such notice to be given at the expense of the Company.

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be eligible under Trust Indenture Act Section
310(a) and this Article Six and shall have a combined capital and surplus of at
least $50,000,000 or which shall be a wholly owned subsidiary of a company that
has a combined capital and surplus of at least $50,000,000 and have a Corporate
Trust Office or an agent selected in accordance with Section 608 hereof without
the execution or filing of any paper or any further act on the part of any of
the parties hereto.

          In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor Trustee and deliver such
Securities so authenticated; and, in case at that time any of the Securities
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor hereunder or in the name
of the successor trustee; and in all such cases such certificate shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have; provided that the right to adopt
the certificate of authentication of any predecessor Trustee or to authenticate
Securities in the name of any predecessor Trustee shall apply only to its
successor or successors by merger, conversion or consolidation.

          If and when the Trustee shall be or become a creditor of the Company
(or other obligor under the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).  A Trustee who has resigned or been

          (a) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture, and no implied covenants
     or obligations shall be read into this Indenture against the Trustee; and

          (b) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture, but in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     be under a duty to examine the same to determine whether or not they
     conform to the requirements of this Indenture but shall not be required to
     verify the contents thereof.

          (2) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

Commission is not permitted under the Exchange Act, promptly upon written
request and payment of the reasonable cost of duplication and delivery, supply
copies of such documents to any prospective Holder of Securities at the
Company's cost.

          (b)  For so long as any of the Securities remain outstanding and are

          Section 1006.  Limitations on Restricted Payments.
                         ---------------------------------- 

          Subject to the other provisions of this Section 1006, the Company
shall not, nor shall it cause, permit or suffer any Restricted Subsidiary to,
(i) declare or pay any dividends or make any other distributions (including
through mergers, liquidations or other transactions) on any class of Equity
Interests of the Company or such Restricted Subsidiary (other than dividends or
distributions payable by a wholly-owned Restricted Subsidiary on account of its
Equity Interests held by the Company or another Restricted Subsidiary or payable
in shares of Capital Stock of the Company other than Redeemable Stock), (ii)
make any payment on account of, or set apart money for a sinking or other
analogous fund for, the purchase, redemption or other retirement of such Equity
Interests, (iii) purchase, defease, redeem or otherwise retire any Indebtedness
issued by the Company or any Restricted Subsidiary that is Subordinated
Indebtedness to the Securities, or (iv) make any Restricted Investment, either
directly or indirectly, whether in cash or property or in obligations of the
Company (all of the foregoing being called "Restricted Payments"), unless (x) in
the case of a dividend, such dividend is payable not more than 60 days after the
date of declaration and (y) after giving effect to such proposed Restricted
Payment, all the conditions set forth in

                                    - 89 -
<PAGE>
 
clauses (1) through (3) below are satisfied (A) at the date of declaration (in
the case of any dividend), (B) at the date of such setting apart (in the case of
any such fund) or (C) on the date of such other payment or distribution (in the
case of any other Restricted Payment) (each such date being referred to as a
"Computation Date"):

          (1)  no Default or Event of Default shall have occurred and be
     continuing or would result from the making of such Restricted Payment;

          (2)  at the Computation Date for such Restricted Payment and after
     giving effect to such Restricted Payment on a pro forma basis, the Company
     or such Restricted Subsidiary could incur $1.00 of additional Indebtedness
     pursuant to the covenant described in the initial paragraph under Section
     1008 hereof; and

          (3)  the aggregate amount of Restricted Payments declared, paid or
     distributed subsequent to the Issue Date (including the proposed Restricted
     Payment) shall not exceed the sum of (i) 50% of the cumulative Consolidated
     Net Income of the Company for the period (taken as one accounting period)
     commencing on the first day of the first full quarter after the Issue Date
     to and including the last day of the Company's last fiscal quarter ending
     prior to the Computation Date (each such period to constitute a
     "Computation Period") (or, in the event Consolidated Net Income of the
     Company during the Computation Period is a deficit, then minus 100% of such
     deficit), (ii) the aggregate Net Cash Proceeds of the issuance or sale or
     the exercise (other than to a Subsidiary or an employee stock ownership
     plan or other trust established by the Company or any of its Subsidiaries
     for the benefit of their employees) of the Company's Equity Interests
     (other than Redeemable Stock) subsequent to the Issue Date, and (iii) $3.0
     million.

          If no Default or Event of Default has occurred and is continuing or
would occur as a result thereof, the prohibitions set forth above are subject to
the following exceptions:  (a) Restricted Investments acquired by the Company in
connection with any Asset Sale consummated in accordance with Section 1009,
hereof, to the extent such Investments are permitted under such covenant,
provided, however, that such Restricted Investments shall be excluded in the

clause (3) of the preceding paragraph; (b) any purchase or redemption of Equity
Interests or Subordinated Indebtedness made by exchange for, or out of the
proceeds of the substantially concurrent sale of, Equity Interests of the
Company (other than Redeemable Stock and other than Equity Interests issued or
sold to a Subsidiary or an employee stock ownership plan), provided, however,

that (x) such

purchase or redemption shall be excluded in the calculation of the amount of
Restricted Payments previously made for purposes of clause (3) of the preceding
paragraph and (y) the Net Cash Proceeds from such sale shall be excluded for
purposes of clause 3(ii) of the preceding paragraph to the extent utilized for
purposes of such purchase or redemption; (c) any purchase or redemption of
Subordinated Indebtedness of the Company made by exchange for, or out of the
proceeds of the substantially concurrent sale of, Subordinated Indebtedness of
the Company or any Restricted Subsidiary which is permitted to be issued
pursuant to the provisions of Section 1008 hereof, provided, however, that such
                                                   --------  -------           
purchase or redemption shall be excluded in the calculation of the amount of
Restricted Payments previously made for purposes of clause (3) of the preceding
paragraph; (d) the purchase of Capital Stock held by employees of the Company or
any Subsidiary pursuant to any employee stock ownership plan thereof upon the
termination, retirement or death of any such employee in accordance with the
provisions of any such plan in an amount not greater than $500,000 in any
calendar year, provided, however, that any such purchase shall be included in
               --------  -------                                             
the calculation of the amount of Restricted Payments previously made for
purposes of clause (3) of the preceding paragraph; and (e) Investments described
in clause (vi) of the definition of Permitted Investments, provided, however,
                                                           --------  ------- 
that such Investments shall be included in the calculation of the amount of
Restricted Payments previously made for purposes of clause (3) of the preceding
paragraph.

          For purposes of this Section 1006, (a) the amount of any Restricted
Payment declared, paid or distributed in property of the Company or any
Restricted Subsidiary shall be deemed to be the net book value of any such
property that is intangible property and the Fair Market Value (as determined in
good faith by and set forth in a resolution of the Board of Directors) of any
such property that is tangible property at the Computation Date, in each case,
after deducting related reserves for depreciation, depletion and amortization;
(b) the amount of any Restricted Payment declared, paid or distributed in
obligations of the Company or any Restricted Subsidiary shall be deemed to be
the principal amount of such obligations as of the date of the adoption of a
resolution by the Board of Directors or such Restricted Subsidiary authorizing
such Restricted Payment; and (c) a distribution to holders of the Company's
Equity Interests of (i) shares of Capital Stock or other Equity Interests of any
Restricted Subsidiary of the Company or (ii) other assets of the Company,
without, in either case, the receipt of equivalent consideration therefor shall
be regarded as the equivalent of a cash dividend equal to the excess of the Fair
Market Value of the Equity Interests or other assets being so distributed at the
time of such distribution over the consideration, if any, received therefor.

                         ---------------------------------------------
Restricted Subsidiaries.
- ----------------------- 

          The Company shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, create or otherwise cause or suffer to exist or
become effective any consensual encumbrance or restriction of any kind on the
ability of any Restricted Subsidiary to (i) pay dividends or make any other
distribution to the Company or its Restricted Subsidiaries on its Equity
Interests, (ii) pay any Indebtedness owed to the Company or any other Restricted
Subsidiary, (iii) make loans or advances to the Company or any other Restricted

other Restricted Subsidiary, except (A) consensual encumbrances or restrictions
contained in or created pursuant to the Credit Agreements and Existing
Indebtedness listed on Schedule 1 hereto, (B) consensual encumbrances or
restrictions in the Securities and the Indenture, (C) any restriction, with
respect to a Restricted Subsidiary of the Company that is not a Subsidiary of
the Company on the Issue Date, in existence at the time such entity becomes a
Restricted Subsidiary of the Company and not created as a result of or in
anticipation of such entity becoming a Restricted Subsidiary of the Company;
provided that such encumbrance or restriction is not created in anticipation of
or in connection with such entity becoming a Subsidiary of the Company and is
not applicable to any Person or the properties or assets of any Person other
than a Person that becomes a Subsidiary, (D) any encumbrances or restrictions
pursuant to an agreement effecting a refinancing of Indebtedness referred to in
clauses (A) or (C) of this Section 1007 or contained in any amendment to any
agreement creating such Indebtedness, provided that the encumbrances and
restrictions contained in any such refinancing or amendment are not more
restrictive taken as a whole (as determined in good faith by the chief financial
officer of the Company) than those provided for in such Indebtedness being
refinanced or amended, (E) encumbrances or restrictions contained in any other
Indebtedness permitted to be incurred subsequent to the Issue Date pursuant to
Section 1008, provided that any such encumbrances or restrictions are not more
restrictive taken as a whole (as determined in good faith by the chief financial
officer of the Company) than the most restrictive of those provided for in the
Indebtedness referred to in clauses (A) or (C) of this Section 1007, (F) any
such encumbrance or restriction consisting of customary nonassignment provisions
in leases governing leasehold interests to the extent such provisions restrict
the transfer of the lease, (G) any restriction with respect to a Restricted
Subsidiary imposed pursuant to an agreement entered into for the sale or
disposition of all or substantially all of the Capital Stock or assets of such
Restricted Subsidiary in compliance with the Indenture pending the closing of
such sale or disposition, provided that such restrictions apply solely to the
Capital Stock or assets of such Restricted Subsidiary which are

                                    - 92 -

being sold; or (H) any encumbrance or restriction due to applicable law.

          Section 1008.  Limitations on Indebtedness.
                         --------------------------- 

          The Company shall not, and shall not permit its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become liable with respect to or become responsible for the payment
of, contingently or otherwise ("incur"), any Indebtedness (including any
Acquired Indebtedness); provided, however, that the Company, or a Restricted
                        --------  -------                                   
Subsidiary of the Company, may incur Indebtedness if at the time of such
incurrence and after giving pro forma effect thereto, the Company's Interest
Coverage Ratio for the most recently ended four full fiscal quarters for which
internal financial statements are available immediately preceding the date on
which such Indebtedness is incurred, calculated on a pro forma basis as if such
Indebtedness was incurred on the first day of such four full fiscal quarter
period, would be at least 2.0 to 1.0.

          Notwithstanding the foregoing, the limitations of this Section 1008
shall not apply to the incurrence of Permitted Indebtedness.

          Section 1009.  Limitations on Asset Sales.
                         -------------------------- 

          (a)  The Company shall not, and shall not permit any Restricted
Subsidiary to, make any Asset Sale (other than to the Company or another
Restricted Subsidiary) unless (i) the Company or such Restricted Subsidiary
receives consideration at the time of such Asset Sale at least equal to the Fair
Market Value of the assets sold or otherwise disposed of, and at least 85% of
the consideration received by the Company or such Restricted Subsidiary from
such Asset Sale is in the form of cash or Cash Equivalents and (ii) the Net
Proceeds received by the Company or such Restricted Subsidiary from such Asset
Sale are applied in accordance with the following paragraphs.

          (b)  (i)  If all or a portion of the Net Proceeds of any Asset Sale
     are not required to be applied to repay permanently any Senior Indebtedness
     of the Company then outstanding as required by the terms thereof, or the
     Company determines not to apply such Net Proceeds to the permanent
     prepayment of any Senior Indebtedness outstanding or if no such Senior
     Indebtedness is then outstanding, then the Company may within 180 days of
     the Asset Sale, invest the Net Proceeds in the Company or one or more
     Restricted Subsidiaries.  The amount of such Net Proceeds neither used to
     permanently repay or prepay Senior Indebtedness nor used or invested as set
     forth in this paragraph constitutes "Excess Proceeds."

                                    - 93 -
<PAGE>
 
          (ii)  When the aggregate amount of Excess Proceeds from one or more
     Asset Sales equals $5,000,000 or more, the Company shall apply 100% of such
     Excess Proceeds within 180 days subsequent to the consummation of the Asset
     Sale which resulted in the Excess Proceeds equalling $5,000,000 or more to
     the purchase of Securities tendered to the Company for purchase at a price
     (the "Asset Sale Purchase Price") equal to 100% of the principal amount
     thereof, plus accrued interest, if any, to the date of purchase pursuant to
     an offer to purchase made by the Company (an "Asset Sale Offer") with
     respect to the Securities. Any Asset Sale Offer may include a pro rata
     offer under similar circumstances to purchase other Senior Indebtedness
     requiring a similar offer.

          (c)  Until such time as the Net Proceeds from any Asset Sale are
applied in accordance with this Section 1009, such Net Proceeds shall be
segregated from the other assets of the Company and the Subsidiaries and
invested in cash or Cash Equivalents, except that the Company or any Restricted
Subsidiary may use any Net Proceeds pending the utilization thereof in the
manner (and within the time period) described above, to repay revolving loans
(under the Credit Agreements or otherwise) without a permanent reduction of the
commitment thereunder.

          (d)  Any Asset Sale Offer shall be made substantially in accordance
with the procedures described under Section 1109 hereof.  The Company shall
cause a notice of any Asset Sale Offer to be mailed to the Holders at their
registered addresses not less than 30 days nor more than 60 days before the
purchase date.  Such notice shall contain all instructions and materials
necessary to enable Holders to tender their Securities to the Company.  Upon
receiving notice of an Asset Sale Offer, Holders may elect to tender their
Securities in whole or in part in integral multiples of $1,000 in exchange for
cash.  To the extent that Holders properly tender Securities in an amount
exceeding the Asset Sale Offer, Securities of tendering Holders shall be
repurchased on a pro rata basis (based on amounts tendered).

          (e)  In the event the Company is required to make an Asset Sale Offer
at a time when the Company is prohibited from making such Offer, the Company
shall, on or prior to the date that the Company is required to make an Asset
Sale Offer, to (i) seek the consent of its lenders to repurchase the Securities
pursuant to such Asset Sale Offer or (ii) refinance the Indebtedness that
prohibits such Asset Sale Offer; provided, however, that the failure to make or
                                 --------  -------                             
consummate the Asset Sale Offer as provided herein shall constitute an Event of
Default.

          (f)  The Company shall comply, to the extent applicable, with the
requirements of Rule 14e-1 under the Exchange Act, any other tender offer rules
under the Exchange Act

                                    - 94 -
<PAGE>
 
and other securities laws or regulations in connection with any offer to
repurchase and the repurchase of the Securities as described above.

          (g)  The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, create or permit to exist or become effective any consensual
restriction (other than restrictions not more restrictive taken as a whole (as
determined in good faith by the chief financial officer of the Company) than
those in effect under Existing Indebtedness, and Indebtedness under the Credit
Agreements) that would materially impair the ability of the Company to comply
with the provisions of this Section 1009.

          Section 1010.  Limitations on Sale and Leaseback Transactions.
                         ---------------------------------------------- 

          The Company shall not, and shall not permit any Restricted Subsidiary
to, enter into any Sale and Leaseback Transaction unless at the time of the
occurrence of such transaction and after giving effect to such transaction and
(x) in the case of a Sale and Leaseback Transaction which is a Capitalized Lease
Obligation, giving effect to the Indebtedness in respect thereof, and (y) in the
case of any other Sale and Leaseback Transaction, giving effect to the
Attributable Indebtedness in respect thereof, the Company or such Restricted
Subsidiary could incur $1.00 of additional Indebtedness pursuant to the covenant
described in the initial paragraph under Section 1008 hereof, (ii) at the time
of the occurrence of such transaction, the Company or such Restricted Subsidiary
could incur Indebtedness secured by a Lien on property in a principal amount
equal to or exceeding the Attributable Indebtedness in respect of such Sale and
Leaseback Transaction pursuant to Section 1012 hereof, and (iii) the transfer of
assets in such Sale and Leaseback Transaction is permitted by, and the Company
applies the proceeds of such transaction in compliance with, Section 1009.

          Section 1011.  Limitations on Transactions With Affiliates.
                         ------------------------------------------- 

          (a)  The Company and its Restricted Subsidiaries shall not, directly
or indirectly, enter into any transaction or series of related transactions with
or for the benefit of any of their respective Affiliates other than with the
Company or any Restricted Subsidiaries, except on an arm's-length basis and if
(x)(i) in the case of any such transaction in which the aggregate remuneration,
rental value or other consideration (including the value of a loan), together
with the aggregate remuneration, rental value or other consideration (including
the value of a loan) of all such other transactions consummated in the year
during which such transaction is proposed to be consummated,

exceeds $500,000, the Company delivers board resolutions to the Trustee
evidencing that the Board of Directors and the Independent Directors that are
disinterested each have (by a majority vote) determined in good faith that such
transaction is in the best interests of the Company and that the aggregate
remuneration, rental value or other consideration (including the value of any
loan) inuring to the benefit of such affiliate from any such transaction is not
greater than that which would be charged to or extended by the Company or its
Subsidiaries, as the case may be, on an arm's-length basis for similar
properties, assets, rights, goods or services by or to a Person not affiliated
with the Company or its Subsidiaries, as the case may be, and (ii) in the case
of any such transaction in which the aggregate remuneration, rental value or
other consideration (including the value of any loan), together with the
aggregate remuneration, rental value or other consideration (including the value
of any loan) of all such other transactions consummated in the year during which
such transactions are proposed to be consummated, exceeds $2.5 million, in
addition to the requirements set forth in clause (x)(i) above, the Company
delivers to the Trustee an opinion evidencing that a nationally recognized
investment banking firm, unaffiliated with the Company and the Affiliate which
is party to such transaction, has determined that the aggregate remuneration,
rental value or other consideration (including the value of a loan) inuring to
the benefit of such Affiliate from any such transaction is not greater than that
which would be charged to or extended by the Company or its Subsidiaries, as the
case may be, on an arm's-length basis for similar properties, assets, rights,
goods or services by or to a Person not affiliated with the Company or its
Subsidiaries, as the case may be, and (y) all such transactions referred to in
clauses x(i) and (ii) of this Section 1011 are entered into in good faith.  Any
transaction required to be approved by Independent Directors pursuant to the
preceding paragraph must be approved by at least one such Independent Director.

          (b)  The provisions of the preceding paragraph do not prohibit (i) any
Restricted Payment permitted to be paid pursuant to the provisions of Section
1006 hereof, (ii) any issuance of securities, or other payments, awards or
grants in cash, securities or otherwise pursuant to, or the funding of,
employment arrangements, stock options and stock ownership plans approved by the
Board of Directors, (iii) loans or advances to employees in the ordinary course
of business consistent with past practices, not to exceed $500,000 aggregate
principal amount outstanding at any time, and (iv) the payment of fees and
compensation to, and indemnity provided on behalf of, officers, directors,
employees or consultants of the Company or any of its Subsidiaries, as
determined by the Board of Directors in good faith and as paid or provided
pursuant to agreements or arrangements entered into in the ordinary course of
business.

                         -------------------- 

          The Company shall not, and shall not permit any Restricted Subsidiary
to, create, incur, assume or suffer to exist any Lien upon any of their
respective assets or properties now owned or acquired after the Issue Date, or
any income or profits therefrom, unless the Securities are directly secured
equally and ratably (or prior to in the case of Liens with respect to

Company is prohibited from purchasing Securities, the Company shall, within
thirty (30) days following a Change of Control (i) seek the consent of its
lenders to the purchase of the Securities or (ii) refinance the Indebtedness

Subsidiaries to, create or permit to exist or become effective any restriction
(other than restrictions not more restrictive taken as a whole (as determined in
good faith by the chief financial officer of the Company) than those in effect
under Existing Indebtedness and Indebtedness under the Credit Agreements) that
would materially impair the ability of the Company to make a Change of Control
Offer to purchase the Securities or, if such Change of Control Offer is made, to
pay for the Securities tendered for purchase.

          If the Company shall at any time act as its own Paying Agent, it
shall, on or before each due date of the principal of, premium, if any, or
interest on any of the Securities, segregate and hold in trust for the benefit
of the Holders entitled thereto a sum sufficient to pay the principal, premium,
if any, or interest so becoming due until such sums shall be paid to such
Persons or otherwise disposed of as herein provided, and shall promptly notify

premium, if any, or interest on any Securities, deposit with a Paying Agent a
sum in same-day funds sufficient to pay the principal, premium, if any, or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such Paying
Agent is the Trustee) the Company shall promptly notify the Trustee of such
action or any failure so to act.

          If the Company is not acting as Paying Agent, the Company shall cause
each Paying Agent other than the Trustee to execute and deliver to the Trustee
an instrument in which such Paying Agent shall agree with the Trustee, subject
to the provisions of this Section, that such Paying Agent shall:

          (a)  hold all sums held by it for the payment of the principal of,
     premium, if any, or interest on Securities in trust for the benefit of the
     Persons entitled thereto until such sums shall be paid to such Persons or
     otherwise disposed of as herein provided;

          (b)  give the Trustee notice of any Default by the Company or any
     Guarantor (or any other obligor upon the

                                    - 102 -
<PAGE>
 
     Securities) in the making of any payment of principal, premium, if any, or
     interest;

          (c)  at any time during the continuance of any such Default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent; and

          (d)  acknowledge, accept and agree to comply in all aspects with the
     provisions of this Indenture relating to the duties, rights and
     disabilities of such Paying Agent.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of, premium, if any,
or interest on any Security and remaining unclaimed for two years after such
principal and premium, if any, or interest has become due and payable shall
promptly be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
                                --------  -------                          
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in the New York Times and The
Wall Street Journal (national edition), notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than thirty
(30) days from the date of such notification or publication, any unclaimed
balance of such money then remaining shall promptly be repaid to the Company.

transaction or a series of related transactions, property or assets (including,

obligations under the Indenture and the Securities on the same terms as the
other Guarantors, which Guarantee shall rank pari passu with any Senior
Indebtedness of such Subsidiary.  The provisions of clauses (ii) and (iii) of
this paragraph shall not apply to any transaction permitted by Section 1009.

such Guarantee is referred to as a "Guarantor."  Notwithstanding the foregoing,
any Guarantee shall be automatically and unconditionally released and discharged
upon any sale, exchange or transfer, to any Person not an Affiliate of the
Company, of all of the Company's Equity Interest in (or if such Subsidiary is
owned by a Restricted Subsidiary, of all of such Restricted Subsidiary's Equity
Interest in), or all or substantially all the assets of, such Subsidiary, which
is in compliance with this Indenture.

     upon surrender of such Security, new Security or Securities in the
     aggregate principal amount equal to the unredeemed portion thereof will be
     issued;

          (e)  that Securities called for redemption must be surrendered to the
     Paying Agent to collect the Redemption Price;

          (f)  that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security or portion thereof, and that (unless
     the Company shall default in payment of the Redemption Price) interest

          Section 1106.  Deposit of Redemption Price.
                         --------------------------- 

          On or prior to 10:00 a.m. New York City time on any Redemption Date,
the Company shall deposit with the Trustee or with a Paying Agent (or if the

to pay the Redemption Price of and (except if the Redemption Date shall be an
Interest Payment Date) accrued interest on, all the Securities or portions
thereof which are to be redeemed on that date.  When the Redemption Date falls
on an Interest Payment Date, payments of interest due on such date are

                                    - 107 -

                         ------------------------------------- 

          Notice of redemption having been given as aforesaid, the Securities so

interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price together with accrued interest to
the Redemption Date; provided, however, that installments of interest whose
                     --------  -------                                     
Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such on the relevant Regular Record Dates according to the terms and the
provisions of Section 309 hereof.

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and premium, if any, shall,
until paid, bear interest from the Redemption Date at the rate borne by such
Security.

          Section 1108.  Securities Redeemed or Purchased in Part.
                         ---------------------------------------- 

          Any Security which is to be redeemed or purchased only in part shall
be surrendered to the Paying Agent at the office or agency maintained for such
purpose pursuant to Section 1002 hereof (with, if the Company, the Security
Registrar or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company, the Security
Registrar or the Trustee duly executed by, the Holder thereof or such Holder's
attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities, of any authorized denomination as
requested by such Holder in aggregate principal amount equal to, and in exchange
for, the unredeemed portion of the principal of the Security so surrendered that
is not redeemed or purchased.

          Section 1109.  Asset Sale Offers.
                         ----------------- 

          In the event that the Company shall commence an Asset Sale Offer
pursuant to Section 1009 hereof, it shall follow the procedures specified below.

          The Asset Sale Offer shall remain open for twenty (20) Business Days
after the date on which such Asset Sale Offer is

                                    - 108 -
<PAGE>
 
commenced (the "Commencement Date") except to the extent required to be extended
pursuant to applicable law (as so extended, the "Asset Sale Offer Period").  No
later than one Business Day after the termination of the Asset Sale Offer Period
(the "Asset Sale Purchase Date"), the Company shall purchase the principal
amount (the "Asset Sale Offer Amount") of Securities required pursuant to
Section 1009 hereof to be purchased in such Asset Sale Offer or, if less than
the Asset Sale Offer Amount has been tendered, all Securities tendered in
response to the Asset Sale Offer.

          If the Asset Sale Purchase Date is on or after a Regular Record Date
and on or before the related Interest Payment Date, any accrued interest shall
be paid to the Person in whose name a Security is registered at the close of
business on such Regular Record Date, and no additional interest shall be
payable to Holders who tender Securities pursuant to the Asset Sale Offer.

          On any Commencement Date, the Company shall send or cause to be sent,
by first class mail, a notice to each of the Holders, with a copy to the
Trustee.  Such notice, which shall govern the terms of the Asset Sale Offer,
shall contain all instructions and materials necessary to enable the Holders to
tender Securities pursuant to the Asset Sale Offer and shall state:

          (1)  that the Asset Sale Offer is being made pursuant to Section 1009
     hereof and this Section 1109 and the length of time the Asset Sale Offer
     shall remain open;

          (2)  the Asset Sale Offer Amount, the Asset Sale Purchase Price and
     the Asset Sale Purchase Date;

          (3)  that any Security not tendered or accepted for payment shall
     continue to accrue interest in accordance with this Indenture;

          (4)  that, unless the Company defaults in the payment of the Asset
     Sale Purchase Price, all Securities accepted for payment pursuant to the
     Asset Sale Offer shall cease to accrue interest after the Asset Sale
     Purchase Date;

          (5)  that Holders electing to have Securities purchased pursuant to
     any Asset Sale Offer shall be required to surrender the Security, with the
     form entitled "Option of Holder to Elect Purchase" on the reverse of the
     Security completed, to the Company, a depositary, if appointed by the
     Company, or a Paying Agent at the address specified in the notice prior to
     the close of business on the Business Day preceding the Asset Sale Purchase
     Date;

                                    - 109 -
<PAGE>
 
          (6)  that Holders shall be entitled to withdraw their election if the
     Company, Depositary or Paying Agent, as the case may be, receives not later
     than the close of business on the Business Day preceding the termination of
     the Asset Sale Offer Period, a telegram, telex, facsimile transmission or
     letter setting forth the name of the Holder, the principal amount of the
     Security the Holder delivered for purchase, the certificate number on the
     Security and a statement that such Holder is withdrawing his election to
     have the Security purchased;

          (7)  that, if the aggregate principal amount of Securities surrendered
     by Holders exceeds the Asset Sale Offer Amount, the Company shall select
     the Securities to be purchased on a pro rata basis (with such adjustments
     as may be deemed appropriate by the Company so that only Securities in
     denominations of $1,000, or integral multiples thereof, shall be
     purchased); and

          (8)  that Holders whose Securities are purchased only in part shall be
     issued new Securities equal in principal amount to the unpurchased portion
     of the Securities surrendered, which unpurchased portion must be equal to
     $1,000 principal amount or an integral multiples thereof.

          On or before 10:00 a.m. New York City time on each Asset Sale Purchase
Date, the Company shall irrevocably deposit with the Trustee or Paying Agent in
immediately available funds the aggregate Asset Sale Purchase Price with respect
to a principal amount of Securities equal to the Asset Sale Offer Amount,
together with accrued interest thereon, to be held for payment in accordance
with the terms of this Section 1109.  On the Asset Sale Purchase Date, the
Company shall, to the extent lawful, (i) accept for payment, on a pro rata basis
to the extent necessary, an aggregate principal amount equal to the Asset Sale
Offer Amount of Securities tendered pursuant to the Asset Sale Offer, or if less
than the Asset Sale Offer Amount has been tendered, all Securities or portions
thereof tendered, (ii) deliver, or cause the Paying Agent or depositary, as the
case may be, to deliver to the Trustee Securities so accepted and (iii) deliver
to the Trustee an Officers' Certificate stating that such Securities or portions
thereof were accepted for payment by the Company in accordance with the terms of
this Section 1109.  The Company, a depositary or Paying Agent, as the case may
be, shall promptly (but in any case not later than two (2) Business Days after
the Asset Sale Purchase Date) mail or deliver to each tendering Holder an amount
equal to the Asset Sale Purchase Price with respect to the Securities tendered
by such Holder and accepted by the Company for purchase, and the Company shall
promptly issue a new Security, and the Trustee shall authenticate and mail or
deliver such new Security, to such Holder, equal in principal amount to any
unpurchased portion of

                                    - 110 -
<PAGE>
 
such Holder's Securities surrendered.  Any Security not accepted in the Asset
Sale Offer shall be promptly mailed or delivered by the Company to the Holder
thereof.  The Company shall publicly announce in a newspaper of general
circulation the results of the Asset Sale Offer on the Asset Sale Purchase Date.

          The Asset Sale Offer shall be made by the Company in compliance with
all applicable laws, including, without limitation, the requirements of Rule
14e-1 under the Exchange Act, any other tender offer rules under the Exchange
Act and all other applicable federal and state securities laws.

          Subject to applicable escheat laws, as provided in the Securities, the
Trustee and the Paying Agent shall return to the Company any cash that remains
unclaimed, together with interest, if any, thereon, held by them for the payment
of the Asset Sale Purchase Price; provided, however, that (x) to the extent that
                                  --------  -------                             
the aggregate amount of an Asset Sale Offer exceeds the aggregate Asset Sale
Purchase Price of the Securities or portions thereof to be purchased, the
Trustee shall hold such excess for the Company and (y) unless otherwise directed
by the Company in writing, promptly after the Business Day following the Asset
Sale Purchase Date the Trustee shall return any such excess to the Company
together with interest or dividends, if any, thereon.

          Other than as specifically provided in this Section 1109, each
purchase pursuant to this Section 1109 shall be made pursuant to the provisions
of Sections 1101 through 1108 hereof.

Indenture Obligations (which for purposes of this Guarantee shall also be deemed
to include all commissions, fees, charges, costs and other expenses (including
reasonable legal fees and disbursements of one counsel) arising out of or
incurred by the Trustee or the Holders in connection with the enforcement of

performance for all Indenture Obligations and shall remain in full force and
effect until the payment in full of all of the Indenture Obligations and shall
apply to and secure any ultimate balance due or remaining unpaid to the Trustee
or the Holders; and this Guarantee shall not be considered as wholly or
partially satisfied by the payment or liquidation at any time or from time to
time of any sum of money for the time being due or remaining unpaid to the
Trustee or the Holders.  Each Guarantor, jointly and severally, covenants and
agrees to comply with all obligations, covenants, agreements and provisions
applicable to it in this Indenture including those set forth in Article Eight.
Without limiting the generality of the foregoing, each of the Guarantors'
liability shall extend to all amounts which constitute part of the Indenture
Obligations and would be owed by the Company under this Indenture and the
Securities but for the fact that they are unenforceable, reduced, limited,
impaired, suspended or not allowable due to the existence of a

bankruptcy, reorganization or similar proceeding involving the Company.

Indenture Obligations shall be paid strictly in accordance with their terms
regardless of any law, regulation or order now or hereafter in effect in any
jurisdiction affecting any of such terms or the rights of the Holders of the
Securities.

          (d) Each Guarantor's liability to pay or perform or cause the
performance of the Indenture Obligations under this Guarantee shall arise
forthwith after demand for payment or performance by the Trustee has been given
to the Guarantors in the manner prescribed in Section 106 hereof.

          (e) Except as provided herein, the provisions of this Article Thirteen
cover all agreements between the parties hereto relative to this Guarantee and
none of the parties shall be bound by any representation, warranty or promise
made by any Person relative thereto which is not embodied herein; and it is
specifically acknowledged and agreed that this Guarantee has been delivered by
each Guarantor free of any conditions whatsoever and that no representations,
warranties or promises have been made to any Guarantor affecting its liabilities
hereunder, and that the Trustee shall not be bound by any representations,
warranties or promises now or at any time hereafter made by the Company to any
Guarantor.

                         -------------------------------- 

          In the event of any demand for payment or performance by the Trustee

Indenture Obligations have been paid in full, and the Guarantors shall continue
to be jointly and severally liable hereunder for any balance which may be owing

upon foreclosure thereon, shall not, as between the Trustee and any Guarantor,
unless otherwise agreed in writing by the Trustee, be considered as a purchase
of such security, or as payment, satisfaction or reduction of the Indenture
Obligations due to the Trustee or the Holders by the Company or any part
thereof.

          Section 1305.  Waivers.
                         ------- 

          (a) Each Guarantor hereby expressly waives (to the extent permitted by
law) notice of the acceptance of this Guarantee and notice of the existence,
renewal, extension or the non-performance, non-payment, or non-observance on the
part of the Company of any of the terms, covenants, conditions and provisions of
this Indenture or the Securities or any other notice whatsoever to or upon the
Company or such Guarantor with respect to the Indenture Obligations.  Each
Guarantor hereby acknowledges communication to it of the terms of this Indenture
and the Securities and all of the provisions therein contained and consents to
and approves the same.  Each Guarantor hereby expressly waives (to the extent
permitted by law) diligence, presentment, protest and demand for payment.

          (b) Without prejudice to any of the rights or recourses which the
Trustee or the Holders may have against the Company, each Guarantor hereby
expressly waives (to the extent permitted by law) any right to require the
Trustee or the Holders to:

          (i)  initiate or exhaust any rights, remedies or recourse against the
     Company, any Guarantor or any other Person;

         (ii)  value, realize upon, or dispose of any security of the Company or
     any other Person held by the Trustee or the Holders; or

        (iii)  initiate or exhaust any other remedy which the Trustee or the
     Holders may have in law or equity;

                                    - 117 -

before requiring or becoming entitled to demand payment from such Guarantor
under this Guarantee.

          Section 1306.  The Guarantors Remain Obligated in Event the Company Is
                         -------------------------------------------------------
No Longer Obligated to Discharge Indenture Obligations.
- ------------------------------------------------------ 

          It is the express intention of the Trustee and the Guarantors that if
for any reason the Company has no legal existence, is or becomes under no legal
obligation to discharge the Indenture Obligations owing to the Trustee or the
Holders by the Company or if any of the Indenture Obligations owing by the
Company to the Trustee or the Holders become irrecoverable from the Company by
operation of law or for any reason whatsoever, this Guarantee and the covenants,
agreements and obligations of the Guarantors contained in this Article Thirteen
shall nevertheless be binding upon the Guarantors, as principal debtor, until
such time as all such Indenture Obligations have been paid in full to the
Trustee and all Indenture Obligations owing to the Trustee or the Holders by the
Company have been discharged, or such earlier time as Section 402 hereof shall
apply to the Securities and the Guarantors shall be responsible for the payment
thereof to the Trustee or the Holders upon demand.

          Section 1307.  Fraudulent Conveyance; Subrogation.
                         ---------------------------------- 

          (a) Any term or provision of this Guarantee to the contrary
notwithstanding, the aggregate amount of the Indenture Obligations guaranteed
hereunder shall be reduced to the extent necessary to prevent this Guarantee
from violating or becoming voidable under applicable law relating to fraudulent
conveyance or fraudulent transfer or similar laws affecting the rights of
creditors generally, including without limitation, Section 123.66 of the Quebec
Companies Act.

          (b) Each Guarantor hereby waives until repayment in full of the
Indenture Obligations and except as provided in Section 1309, all rights of
subrogation or contribution, whether arising by contract or operation of law
(including, without limitation, any such right arising under federal bankruptcy
law) or otherwise by reason of any payment by it pursuant to the provisions of
this Article Thirteen.

          Section 1308.  Guarantee Is in Addition to Other Security.
                         ------------------------------------------ 

          This Guarantee shall be in addition to and not in substitution for any
other guarantees or other security which the Trustee may now or hereafter hold
in respect of the Indenture Obligations owing to the Trustee or the Holders by
the Company and (except as may be required by law) the Trustee shall be under no
obligation to marshal in favor of each of the Guarantors any

                                    - 118 -
<PAGE>
 
other guarantees or other security or any moneys or other assets which the
Trustee may be entitled to receive or upon which the Trustee or the Holders may
have a claim.

          Section 1309.  Contribution.
                         ------------ 

          In order to provide for just and equitable contribution among the
Guarantors, the Guarantors agree, inter se, that in the event any payment or
                                  ----- --                                  
distribution is made by any Guarantor (a "Funding Guarantor") under its
Guarantee, such Funding Guarantor shall be entitled to a contribution from all
other Guarantors in a pro rata amount based on the "Adjusted Net Assets" (as
                      --- ----                                              
defined below) of each Guarantor (including the Funding Guarantor) for all
payments, damages and expenses incurred by that Funding Guarantor in discharging
the Company's obligations with respect to the Securities or any other
Guarantor's obligation with respect to its Guarantee.  "Adjusted Net Assets"
means, with respect to any Guarantor, at any date, the lesser of the amount by
which (x) the fair value of the property of such Guarantor exceeds the total
amount of liabilities, including, without limitation, contingent liabilities
(after giving effect to all other fixed and contingent liabilities incurred or
assumed on such date), but excluding liabilities under the Guarantee, of such
Guarantor at such date and (y) the present fair salable value of assets of such
Guarantor at such date exceeds the amount that shall be required to pay the
probable liability of such Guarantor on its debts (after giving effect to all
other fixed and contingent liabilities incurred or assumed on such date),
excluding debt in respect of its Guarantee, as they become absolute and matured.

          Section 1310.  No Bar to Further Actions.
                         ------------------------- 

          Except as provided by law, no action or proceeding brought or
instituted under Article Thirteen and this Guarantee and no recovery or judgment
in pursuance thereof shall be a bar or defense to any further action or
proceeding which may be brought under Article Thirteen and this Guarantee by
reason of any further default or defaults under Article Thirteen and this
Guarantee or in the payment of any of the Indenture Obligations owing by the
Company.

          Section 1311.  Failure to Exercise Rights Shall Not Operate as a
                         -------------------------------------------------
Waiver.
- ------ 

          No failure to exercise and no delay in exercising, on the part of the
Trustee or the Holders, any right, power, privilege or remedy under this Article
Thirteen and this Guarantee shall operate as a waiver thereof, nor shall any
single or partial exercise of any rights, power, privilege or remedy preclude
any other or further exercise thereof, or the exercise of any other rights,
powers, privileges or remedies.  The rights

                                    - 119 -
<PAGE>
 
and remedies herein provided for are cumulative and not exclusive of any rights
or remedies provided in law or equity.

          Section 1312.  Trustee's Duties; Notice to Trustee.
                         ----------------------------------- 

          (a) Any provision in this Article Thirteen or elsewhere in this
Indenture allowing the Trustee to request any information or to take any action
authorized by, or on behalf of any Guarantor, shall be subject to Section 602(d)
and shall be permissive and shall not be obligatory on the Trustee except as the
Holders may direct in accordance with the provisions of this Indenture or where
the failure of the Trustee to request any such information or to take any such
action arises from the Trustee's gross negligence, bad faith or willful
misconduct.

          (b) The Trustee shall not be required to inquire into the existence,
powers or capacities of the Company, any Subsidiary Guarantor or the officers,
directors or agents acting or purporting to act on their respective behalf.

          Section 1313.  Successors and Assigns.
                         ---------------------- 

          All terms, agreements and conditions of this Article Thirteen shall
extend to and be binding upon each Guarantor and its successors and permitted
assigns and shall enure to the benefit of and may be enforced by the Trustee and
its successors and assigns; provided, however, that the Guarantors may not
                            --------  -------                             
assign any of their rights or obligations hereunder other than in accordance
with Article Eight.

          Section 1314.  Release of Guarantee.
                         -------------------- 

          Concurrently with the payment in full of all of the Indenture
Obligations, the Guarantors shall be released from and relieved of their
obligations under this Article Thirteen.  Upon the delivery by the Company to
the Trustee of an Officers' Certificate and, if requested by the Trustee, an
Opinion of Counsel to the effect that the transaction giving rise to the release
of this Guarantee was made by the Company in accordance with the provisions of
this Indenture and the Securities, the Trustee shall execute any documents
reasonably required in order to evidence the release of the Guarantors from
their obligations under this Guarantee.  If any of the Indenture Obligations are
revived and reinstated after the termination of this Guarantee, then all of the
obligations of the Guarantors under this Guarantee shall be revived and
reinstated as if this Guarantee had not been terminated until such time as the
Indenture Obligations are paid in full, and each Guarantor shall enter into an
amendment to this Guarantee, reasonably satisfactory to the Trustee, evidencing
such revival and reinstatement.

                                    - 120 -
<PAGE>
 
          This Guarantee shall terminate with respect to each Guarantor and
shall be automatically and unconditionally released and discharged as provided
in Section 1019(b) hereof.

          Section 1315.  Execution of Guarantee.
                         ---------------------- 

          To evidence the Guarantee, each Guarantor hereby agrees to execute the
guarantee substantially in the form set forth in Section 206 hereof, to be
endorsed on each Security authenticated and delivered by the Trustee and that
this Indenture shall be executed on behalf of each Guarantor by its Chairman of
the Board, its President, or one of its Vice Presidents, under its corporate
seal reproduced thereon attested by its Secretary or one of its Assistant
Secretaries.  The signature of any of these officers on the Securities may be
manual or facsimile.

          If an officer whose signature is on this Indenture no longer holds
that office at the time the Trustee authenticates a Security on which a
Guarantee is endorsed, such Guarantee shall be valid nevertheless.

          Section 1316.  Payment Permitted by Each of the Subsidiary Guarantors
                         ------------------------------------------------------
if No Default.
- ------------- 

          Nothing contained in this Article, elsewhere in this Indenture or in
any of the Securities shall affect the obligation of any Guarantor to make, or
prevent any Guarantor from making at any time, payments pursuant to the
Securities.

          Section 1317.  Notice to Trustee by Each of the Guarantors.  Each
                         -------------------------------------------       
Guarantor shall give prompt written notice to the Trustee of any fact known to
such Guarantor which would prohibit the making of any payment to or by the
Trustee in respect of the Guarantee.  Notwithstanding the provisions of this
Article or any provision of this Indenture, the Trustee shall not be charged
with knowledge of the existence of any facts which would prohibit the making of
any payment to or by the Trustee in respect of the Securities, unless and until
the Trustee shall have received written notice thereof from any Guarantor or any
trustee, fiduciary or agent therefor; and, prior to the receipt of any such
written notice, the Trustee shall be entitled in all respects to assume that no
such facts exist; provided, however, that if the Trustee shall not have received
                  --------  -------                                             
the notice provided for in this Section at least three (3) Business Days prior
to the date upon which by the terms hereof any money may become payable for any
purpose (including, without limitation, the payment of the principal of,
premium, if any, or interest on any Security or any other Indenture
Obligations), then, anything herein contained to the contrary notwithstanding,
the Trustee shall have full power and authority to receive such money and to
apply the same to the purpose for which such money was received and shall not be
affected by any notice to the contrary which may be received by

                                    - 121 -
<PAGE>
 
it after such date; nor shall the Trustee be charged with knowledge of the
curing of any such default or the elimination of the act or condition preventing
any such payment unless and until the Trustee shall have received an Officers'
Certificate to such effect.

          Section 1318.  Article Applicable to Paying Agents.
                         ----------------------------------- 

          In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting under this Indenture, the term
"Trustee" as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this Article in addition to or in place of the Trustee; provided,
                                                                      -------- 
however, that this Section 1318 shall not apply to the Company or any Affiliate
- -------                                                                        
of the Company if it or such Affiliate acts as Paying Agent.

          Section 1319.  No Suspension of Remedies.
                         ------------------------- 

          Nothing contained in this Article shall limit the right of the Trustee
or the Holders of Securities to take any action to accelerate the maturity of
the Securities pursuant to the provisions described under Article Five and as
set forth in this Indenture or to pursue any rights or remedies hereunder or
under applicable law.

                                    - 122 -

          IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed, all as of the day and year first above written.

Dear Ladies and Gentlemen:

          In connection with our proposed purchase of $________ aggregate
principal amount of 10% Senior Notes due 2003 (the "Notes") of Radnor Holdings
                                                    -----                     
Corporation, a Delaware corporation (the "Company"), we confirm that:
                                          -------                    

          1.  We understand that the Notes and the Guarantees thereon (together,
     the "Securities") have not been registered under the Securities Act of
          ----------                                                       
     1933, as amended (the "Securities Act") or under the securities laws of any
                            --------------                                      
     state and, unless so registered, may not be sold except as permitted in the
     following sentence.  We agree on our own behalf and on behalf of any
     investor account for which we are purchasing Securities to offer, sell or
     otherwise transfer such Securities prior to the date which is three years
     after the later of the date of original issue and the last date on which
     the Company or any affiliate of the Company was the owner of such
     Securities (or any predecessor thereto) (the "Resale Restriction
                                                   ------------------

     ----------------                                                          
     statement which has been declared effective under the Securities Act, (c)
     so long as the Securities are eligible for resale pursuant to Rule 144A
     under the Securities Act, to a person we reasonably believe is a qualified
     institutional buyer under Rule 144A (a "QIB") that purchases for its own
                                             ---                             
     account or for the account of a QIB and to whom notice is given that the
     transfer is being made in reliance on Rule 144A, (d) pursuant to offers and
     sales to non-U.S. persons that occur outside the United States of America
     within the meaning of Regulation S under the Securities Act, (e) to an
     institutional "accredited investor" within the meaning of subparagraph
     (a)(1), (2), (3) or (7) of Rule 501 under the
<PAGE>
 
                                      A-2

     Securities Act that is purchasing for his own account or for the account of
     such an institutional "accredited investor," in each case in a minimum
     principal amount of Senior Notes of $250,000, for investment purposes and
     not with a view to, or for offer or sale in connection with, any
     distribution thereof in violation of the Securities Act or (f) pursuant to
     any other available exemption from the registration requirements of the
     Securities Act, subject in each of the foregoing cases to any requirement
     of law that the disposition of our property or the property of such
     investor account or accounts be at all times within our or their control
     and to compliance with any applicable state securities laws.  The foregoing
     restrictions on resale shall not apply subsequent to the Resale Restriction
     Termination Date.  If any resale or other transfer of the Securities is
     proposed to be made pursuant to clause (e) above prior to the Resale
     Restriction Termination Date, the transferor shall deliver a letter from
     the transferee substantially in the form of this letter to the Trustee,
     which shall provide, among other things, that the transferee is an
     institutional "accredited investor" within the meaning of subparagraph
     (a)(1), (2), (3) or (7) of Rule 501 under the Securities Act and that it is
     acquiring such Securities for investment purposes and not for distribution
     in violation of the Securities Act.  We acknowledge on our own behalf and
     on behalf of any investor account for which we are purchasing Securities
     that the Company and the Trustee reserve the right prior to any offer, sale
     or other transfer prior to the Resale Restriction Termination Date of the
     Securities pursuant to clauses (d), (e) or (f) above to require the
     delivery of an opinion of counsel, certifications and/or other information
     satisfactory to the Company and the Trustee.

          2.  We are an institutional "accredited investor" (as defined in Rule
     501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act)
     purchasing for our own account or for the account of such an institutional
     "accredited investor," and we are acquiring the Securities for investment
     purposes and not with a view to, or for offer or sale in connection with,
     any distribution in violation of the Securities Act and we have such
     knowledge and experience in financial and business matters as to be capable

          --------------------------------------------------                 
pursuant to the Securities Act in which securities of the Company are sold to an
underwriter for reoffering to the public.

          2.   Exchange Offer
               --------------

          (a)  The Issuers shall file with the SEC, no later than the Filing
Date, a registration statement under the Securities Act with respect to a
registered offer to exchange (the "Exchange Offer") any and all of the
                                   -------- -----                     
Registrable Securities (other than Private Exchange Securities, if any) for a
like aggregate principal amount of debt securities of the Company which are
identical in all material respects to the Notes (the "Exchange Notes"), and
                                                      --------------       
which will be fully and unconditionally guaranteed on the same basis as the
Guarantees by the Guarantors (such guarantees, together with the Exchange Notes,
the "Exchange Securities") except that the Exchange Securities shall have been
     -------------------                                                      
registered pursuant to an effective Registration Statement under the Securities
Act and shall contain no restrictive legend thereon, and which are entitled to
the benefits of the Indenture or a trust indenture which is identical in all
material respects to the Indenture (other than such changes to the Indenture or
any such identical trust indenture as are necessary to comply with any
requirements of the SEC to effect or maintain the qualification thereof under
the TIA) and which, in either case, has been qualified under the TIA.  The
Exchange Offer shall be registered under the Securities Act on an appropriate
form under the Securities Act (the "Exchange Offer Registration Statement") and
                                    -------------------------------------      
shall comply with Regulation 14E and Rule 13e-4 under the Exchange Act (other
than the filing requirements of Rule 13e-4).  The Issuers shall use their best
efforts to cause the Exchange Offer Registration Statement to be declared
effective under the Securities Act on or before the Effectiveness Date.  Upon
the Exchange Offer Registration Statement being declared effective, the Issuers
will offer the Exchange Securities in exchange for surrender of the Registrable
Securities.  The Issuers will keep the Exchange Offer open for at least 20
Business Days (or longer if required by applicable law) after the commencement
of the Exchange Offer.  For purposes of this Section 2(a) only, if after such
Exchange Offer Registration Statement is initially declared effective by the
SEC, the Exchange Offer or the issuance of the Exchange Securities thereunder is
interfered with by any stop order, injunction or other similar order or
requirement of the SEC or any other governmental agency or court, such Exchange
Offer Registration Statement shall be deemed not to have become effective for
purposes of this Agreement during the period that such stop order, injunction or
other similar order or requirement shall remain in effect.  Each Holder who
participates in the Exchange Offer will be required to represent that any
Exchange Securities received by it will be acquired in the ordinary course of
its business, that at the time of the consummation of the

                                       5
<PAGE>
 
Exchange Offer such Holder will have no arrangement or understanding with any
Person to participate in the distribution (within the meaning of the Securities
Act) of the Exchange Securities, and that such Holder is not an affiliate of the
Company or any of the Guarantors within the meaning of the Securities Act, or if
it is such an affiliate, that it will comply with the registration and
prospectus delivery requirements of the Securities Act to the extent applicable
to it.  Upon consummation of the Exchange Offer in accordance with this Section
2, the provisions of this Agreement shall continue to apply, mutatis mutandis,
                                                             ------- -------- 
solely with respect to Registrable Securities that are Private Exchange
Securities and Exchange Securities held by Participating Broker-Dealers, and the
Issuers shall have no further obligation to register Registrable Securities
pursuant to Section 3 hereof (other than Private Exchange Securities and other
than in respect of any Exchange Securities as to which Section 2(c)(iv) hereof
applies).  No securities other than the Exchange Securities shall be included in
the Exchange Offer Registration Statement.

          (b)  The Issuers shall include within the Prospectus contained in the
Exchange Offer Registration Statement certain information necessary to allow a
broker-dealer who holds Securities that were acquired for its own account as a
result of marketmaking activities or other ordinary course trading activities
(other than Securities acquired directly from the Issuers or one of the Issuers'
affiliates) to exchange such Securities pursuant to the Exchange Offer and to
satisfy the prospectus delivery requirements in connection with resales of
Exchange Securities received by such broker-dealer in the Exchange Offer,
including a section entitled "Plan of Distribution," reasonably acceptable to
the Initial Purchasers, which shall contain a summary statement of the positions
taken or policies made by the Staff of the Division of Corporation Finance of
the SEC (the "Staff") with respect to the potential "underwriter" status of any
              -----                                                            
broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the
Exchange Act) of Exchange Securities received by such broker-dealer in the
Exchange Offer (a "Participating Broker-Dealer"), whether such positions or
                   ---------------------------                             
policies have been publicly disseminated by the Staff or such positions or
policies, in the judgment of the Initial Purchasers and the Company, represent
the prevailing views of the Staff, including a statement that any such broker-
dealer who receives Exchange Securities for Registrable Securities pursuant to
the Exchange Offer may be deemed to be an "underwriter" within the meaning of
the Securities Act and must deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of such Exchange Securities, which
prospectus delivery requirement may be satisfied by the delivery of the final
Prospectus contained in the Exchange Offer Registration Statement.  Such "Plan
of Distribution" section shall also state that the delivery by a Participating
Broker-Dealer of the final Prospectus relating to the Exchange Offer in
connection with resales of Exchange Securities shall not be deemed to be an
admission by such Participating Broker-Dealer

                                       6
<PAGE>
 
that it is an "underwriter" within the meaning of the Securities Act, and shall
contain all other information with respect to resales of the Exchange Securities
by Participating Broker-Dealers that the SEC may require in connection
therewith, but such "Plan of Distribution" shall not name any such Participating
Broker-Dealer or disclose the principal amount of Exchange Securities held by
any such Participating Broker-Dealer, except to the extent required by the
Staff. Such "Plan of Distribution" section shall also expressly permit the use
of the Prospectus by all Persons subject to the prospectus delivery requirements
of the Securities Act, including all Participating Broker-Dealers, and include a
statement describing the means by which Participating Broker-Dealers may resell
the Exchange Securities.  Each broker-dealer that receives Exchange Securities
for its own account in exchange for Securities where such Securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities must acknowledge that it will comply with any prospectus
delivery requirements under the Securities Act in connection with any resale of
Exchange Securities.

          The Issuers shall use their best efforts to keep the Exchange Offer
Registration Statement effective and to amend and supplement the Prospectus
contained therein, in order to permit such Prospectus to be lawfully delivered
by all Persons subject to the prospectus delivery requirements of the Securities
Act for such period of time as is necessary to comply with applicable law in
connection with any resale of the Exchange Securities; provided, however, that
                                                       --------  -------      
such period shall not exceed 150 days after the Exchange Offer Registration
Statement is declared effective (or such longer period if extended pursuant to
the last paragraph of Section 5 hereof) (the "Applicable Period").
                                              -----------------   

          If, prior to consummation of the Exchange Offer, either Initial
Purchaser holds any Securities acquired by it and having, or which are
reasonably likely to be determined to have, the status of an unsold allotment in
the initial distribution, or any other Holder is not entitled to participate in
the Exchange Offer, the Issuers upon the request of the Initial Purchasers or
any such Holder shall simultaneously with the delivery of the Exchange
Securities in the Exchange Offer, issue and deliver to such Initial Purchaser
and any such Holder, in exchange (the "Private Exchange") for such Securities
                                       ----------------                      
held by such Initial Purchaser and any such Holder, a like principal amount of
debt securities of the Company and guarantees of the Guarantors with respect
thereto that are identical in all material respects to the Exchange Notes and
the guarantees with respect thereto, except for any such restrictions on
transfer that, in the opinion of counsel for the Issuers, are required under the
Securities Act (the "Private Exchange Securities"), and which are issued
                     ---------------------------                        
pursuant to the same indenture as the Exchange Securities; provided, however,
                                                           --------  ------- 
the Issuers shall not be required to effect such exchange if, in the written
opinion of counsel for the Issuers (a copy of which shall be delivered to such
Initial Purchaser and any Holder affected thereby), such exchange cannot

                                       7
<PAGE>
 
be effected without registration under the Securities Act.  The Private Exchange
Securities shall bear the same CUSIP number as the Exchange Securities.

          Interest on the Exchange Securities and the Private Exchange
Securities will accrue from (A) the later of (i) the last interest payment date
on which interest was paid on the Securities surrendered in exchange therefor or
(ii) if the Securities are surrendered for exchange on a date in a period which
includes the record date for an interest payment date to occur on or after the
date of such exchange and as to which interest will be paid, the date of such
interest payment date or (B) if no interest has been paid on the Securities,
from the Issue Date.

          In connection with the Exchange Offer, the Company shall:

          (1)  mail to each Holder a copy of the Prospectus forming part of the
     Exchange Offer Registration Statement, together with an appropriate letter
     of transmittal and related documents;

          (2)  utilize the services of a depositary for the Exchange Offer with
     an address in The City of New York;

          (3)  permit Holders to withdraw tendered Securities at any time prior
     to the close of business, New York time, on the last Business Day on which
     the Exchange Offer shall remain open, by sending to the institution
     specified in the notice, a telegram, telex, facsimile transmission or
     letter setting forth the name of the Holder, the principal amount of
     Securities delivered for exchange, and a statement that such Holder is
     withdrawing its election to have such Securities or a portion thereof
     exchanged;

          (4) notify each Holder that any Security not tendered will remain
     outstanding and continue to accrue interest, but will not retain any rights
     under this Agreement (except in the case of the Initial Purchasers and
     Participating Broker-Dealers as provided herein); and

          (5)  otherwise comply in all material respects with all applicable
     laws, rules and regulations.

          As soon as practicable after the expiration of the Exchange Offer or
the Private Exchange, as the case may be, the Company shall:

          (1)  accept for exchange all Securities properly tendered and not
     validly withdrawn pursuant to the Exchange Offer or the Private Exchange;

          (2)  deliver to the Trustee for cancellation all Securities so
     accepted for exchange; and

                                       8
<PAGE>
 
          (3)  cause the Trustee to authenticate and deliver promptly to each
     Holder of Securities, Exchange Securities or Private Exchange Securities,
     as the case may be, equal in principal amount to the Securities of such
     Holder so accepted for exchange.

          The Exchange Offer and any Private Exchange shall not be subject to
any conditions, other than that the Exchange Offer or such Private Exchange, as
the case may be, does not violate applicable law including, without limitation,
the Securities Act or the Exchange Act, or any applicable interpretation of the
Staff.

          The Exchange Securities and any Private Exchange Securities may be
issued under (i) the Indenture or (ii) an indenture identical in all material
respects to the Indenture, which in either event shall provide that the Exchange
Securities shall not be subject to the transfer restrictions set forth in the
Indenture (and that the Private Exchange Securities shall be subject only to any
such restrictions on transfer that, in the opinion of counsel for the Issuers,
are required under the Securities Act).  The Indenture or such indenture shall
provide that the Exchange Securities, any Private Exchange Securities and the
Securities shall vote and consent together on all matters as one class and that
neither the Exchange Securities, any Private Exchange Securities or the
Securities will have the right to vote or consent as a separate class on any
matter.

          (c)  If (i) the Company determines in reasonably good faith that (x)
because of any change in law or in the applicable interpretations of the Staff,
the SEC is not likely to permit the Issuers to effect the Exchange Offer prior
to the Effectiveness Date, or (y) that the Exchange Securities would not be
tradeable upon receipt by the Holders that participate in the Exchange Offer
without restriction under applicable state and Federal securities laws (other
than due solely to the status of a Holder as an affiliate of the Company or any
of the Guarantors within the meaning of the Securities Act or by breach by a
Holder of its representation described in the third to the last sentence of
Section 2(a) hereof), (ii) the Exchange Offer is not consummated within 150 days
after the Issue Date, (iii) any holder of Private Exchange Securities so
requests, or (iv) in the case of any Holder that participates in the Exchange
Offer, such Holder does not receive Exchange Securities on the date of the
exchange that may be sold without restriction under state and Federal securities
laws (other than due solely to the status of such Holder as an affiliate of the
Company or any of the Guarantors within the meaning of the Securities Act or by
breach by such Holder of its representation described in the third to the last
sentence of Section 2(a) hereof) and so notifies the Company within 60 days
after such Holder first becomes aware of any such restriction and concurrently
therewith provides the Company with a reasonable basis for its conclusion, then,
in the case of each of clauses (i), (ii), (iii) and (iv) of this sentence, the
Issuers shall promptly deliver to the Holders of Registrable

                                       9

Securities and the Trustee written notice thereof (the "Shelf Notice") and shall

               ------------------

          If a Shelf Notice is delivered as contemplated by Section 2(c) hereof,
then:

          (a)  Shelf Registration.  The Issuers shall as promptly as practicable
               ------------------                                               
file with the SEC a Registration Statement for an offering to be made on a
continuous basis pursuant to Rule 415 covering all of the Registrable Securities
(the "Shelf Registration Statement").  If the Issuers shall not have filed an
      ----------------------------                                           
Exchange Offer Registration Statement, the Issuers shall use their best efforts
to file with the SEC the Shelf Registration Statement on or prior to the Filing
Date.  Otherwise, the Issuers shall use their best efforts to file with the SEC
the Shelf Registration Statement on or prior to the 30th day after the delivery
of the Shelf Notice (the "Shelf Filing Date").  The Shelf Registration Statement
                          -----------------                                     
shall be on Form S-1 or another appropriate form under the Securities Act
permitting registration of such Registrable Securities for resale by Holders in
the manner or manners designated by them (including, without limitation, one or
more underwritten offerings).  The Issuers shall not permit any securities other
than the Registrable Securities to be included in the Shelf Registration
Statement or any Subsequent Shelf Registration Statement.

          The Issuers shall use their best efforts to cause the initial Shelf
Registration Statement to be declared effective under the Securities Act on or
before the 120th day after the Shelf Filing Date and to keep the Shelf
Registration Statement continuously effective under the Securities Act until the
date which is 36 months from its effective date, subject to extension pursuant
to the last paragraph of Section 5 hereof (the "Effectiveness Period"), or such

shorter period ending when (i) all Registrable Securities covered by the Shelf
Registration Statement have been sold in the manner set forth and as
contemplated in the initial Shelf Registration Statement or (ii) a Subsequent
Shelf Registration Statement covering all of the Registrable Securities has been
declared effective under the Securities Act.

          (b)  Subsequent Shelf Registrations.  If the initial Shelf
               ------------------------------                       
Registration Statement or any Subsequent Shelf Registration Statement ceases to
be effective for any reason at any time during the Effectiveness Period (other
than because of the sale of all of the securities registered thereunder), the
Issuers shall use their best efforts to obtain the prompt withdrawal of any
order suspending the effectiveness thereof, and in any event shall within 15
days of such cessation of effectiveness amend the Shelf Registration Statement
in a manner to obtain the withdrawal of the order suspending the effectiveness
thereof, or file an additional "shelf" Registration Statement pursuant to Rule
415

- ----------------------

Registration to be declared effective under the Securities Act as soon as
practicable after such filing and to keep such Registration Statement
continuously effective for a period equal to the number of days in the
Effectiveness Period less the aggregate number of days during which the Shelf
Registration Statement and any other Subsequent Shelf Registration was
previously continuously effective.  As used herein the term "Shelf Registration

supplement and amend the Shelf Registration Statement if required by the rules,

Shelf Registration Statement, if required by the Securities Act, or if requested
by the Holders of a majority in aggregate principal amount of the Registrable
Securities covered by such Registration Statement or by any underwriter of such
Registrable Securities, and the Issuers agree to furnish to the Holders of
Registrable Securities copies of any such supplement or amendment promptly after

          (d)  Hold-Back Agreements
               --------------------

          (1)  Restrictions on Public Sale by Holders of Registrable Securities.
               ---------------------------------------------------------------- 
     Each Holder of Registrable Securities whose Registrable Securities are
     covered by a Shelf Registration Statement filed pursuant to this Section 3
     (which Registrable Securities are not being sold in the underwritten
     offering described below) agrees, if requested (pursuant to a timely
     written notice) by the Issuers or the managing underwriter or underwriters
     in an underwritten offering, not to effect any public sale or distribution
     of any of the Registrable Securities or a similar security of the Company,
     including a sale pursuant to Rule 144 or Rule 144A (except as part of such
     underwritten offering), during the period beginning 20 days prior to, and
     ending 90 days after, the closing date of each underwritten offering made
     pursuant to such Shelf Registration Statement, to the extent timely
     notified in writing by the Issuers or by the managing underwriter or
     underwriters; provided, however, that each holder of Registrable Securities
                   --------  -------                                            
     shall be subject to the holdback restrictions of this Section 3(d)(1) only
     once during the term of this Agreement.

          The foregoing provisions shall not apply to any Holder if such Holder
     is prevented by applicable statute or regulation from entering into any
     such agreement; provided, however, that any such Holder shall undertake, in
                     --------  -------

     of securities covered by such Shelf Registration Statement (except as part
     of such underwritten offering) during such period unless it has provided 30
     days' prior written notice of such sale or distribution to the Issuers or
     the managing underwriter or underwriters, as the case may be.

          (2)  Restrictions on the Issuers and Others.  The Issuers agree (A)
               --------------------------------------                        
     not to effect any public or private sale or distribution (including,
     without limitation, a sale pursuant to Regulation D under the Securities
     Act) of any securities of the same class as or similar to those covered by
     a Shelf Registration Statement filed pursuant to this Section 3, or any
     securities convertible into or exchangeable or exercisable for such
     securities, during the period beginning 20 days prior to, and ending 90
     days after, the commencement of an underwritten public distribution of
     Registrable Securities, where the managing underwriter or underwriters of
     such distribution so requests; (B) to include in any agreements entered
     into by the Issuers on or after the date of this Agreement (other than any
     underwriting agreement relating to a public offering registered under the
     Securities Act) pursuant to which the Issuers issue or agree to issue
     securities of the same class as or similar to the Securities a provision
     that each holder of such securities that are of the same class as or
     similar to Securities issued at any time on or after the date of this
     Agreement agrees not to effect any public or private sale or distribution,
     or request or demand the registration, of any such securities (or any
     securities convertible into or exchangeable or exercisable for such
     securities) during the period referred to in clause (A) of this Section
     3(d)(2), including any sale pursuant to Rule 144 or Rule 144A; and (C) not
     to grant or agree to grant any "piggy-back registration" or other similar
     rights to any holder of the Issuers' or any of their respective

          4.   Additional Interest
               -------------------

          (a)  The Issuers and the Initial Purchasers agree that the Holders of
Securities will suffer damages if the Issuers fail to fulfill their obligations
under Section 2 or Section 3 hereof and that it would not be feasible to
ascertain the extent of such damages with precision.  Accordingly, the Issuers
jointly and severally agree to pay, as liquidated damages and as set forth in
the Indenture and the Notes, additional interest on the Notes ("Additional
                                                                ----------
Interest") under the circumstances and to the extent set forth below (each such
- --------                                                                       
event referred to in clauses (i) through (v) below, a "Registration Default"):
                                                       --------------------   

               (i) if the Exchange Offer Registration Statement has not been
     filed on or prior to the Filing Date;

                                      12
<PAGE>
 
               (ii)   if the Exchange Offer Registration Statement has not been
     declared effective on or prior to the Effectiveness Date;

               (iii)  if the Exchange Offer has not been consummated within 150
     days after the Closing Date;

               (iv)   if the Shelf Registration has not been filed on or prior
     to the Shelf Filing Date or declared effective within 120 days following
     the delivery of the Shelf Notice, as the case may be; or

               (v)    if (A) the Exchange Offer Registration Statement has been
     declared effective but ceases to be effective for a period of 15
     consecutive days without being succeeded immediately by any additional
     Registration Statement filed with the SEC and declared effective at any
     time prior to the time that the Exchange Offer is consummated or (B) the
     Shelf Registration or any Subsequent Shelf Registration has been declared
     effective and such Shelf Registration ceases to be effective at any time
     during the Effectiveness Period for a period of 15 consecutive days without
     being succeeded immediately by any additional Registration Statement filed
     and declared effective,

then Additional Interest shall be accrued on the Notes over and above the
interest rate then applicable to the Notes on each day during the first 90-day
period immediately following the occurrence of such Registration Default, at a
rate equal to 25 basis points (0.25%) per annum.  The amount of Additional
Interest will increase by an additional 25 basis points (0.25%) per annum during
each subsequent 90-day period until the applicable Registration Statement is
filed, the applicable Registration Statement is declared effective, the Exchange
Offer is consummated or the applicable Registration Statement again becomes
effective, as the case may be, provided, however, that the Additional Interest
                               --------  -------                              
rate on the Notes may not exceed 100 basis points (1.00%) per annum and,
accordingly, the maximum interest rate on the Notes may not exceed 11%; and
provided, further, that (1) upon the filing of the Exchange Offer Registration
- --------  -------                                                             
Statement (in the case of (i) above), (2) upon the effectiveness of the Exchange
Offer Registration Statement (in the case of (ii) above), (3) upon the
consummation of the Exchange Offer (in the case of (iii) above), (4) upon the
filing of the Shelf Registration or upon the effectiveness of a Shelf
Registration, as applicable (in the case of (iv) above), or (5) upon the
effectiveness of the Exchange Offer Registration Statement which had ceased to
remain effective (in the case of (v)(A) above), or upon the effectiveness of the
Shelf Registration which had ceased to remain effective (in the case of (v)(B)
above), the interest rate borne by the Notes, including Additional Interest,
will be reduced by the amount of Additional Interest on the Notes as a result of
such clause (i), (ii), (iii), (iv) or (v) (or the relevant subclause thereof),
as the case may be.

                                      13
<PAGE>
 
          Notwithstanding the foregoing, the Issuers shall not be required to
pay such Additional Interest with respect to the Registrable Securities held by
a Holder if the applicable Registration Default arises from the failure of the
Issuers to file, or cause to become effective, a Shelf Registration Statement
within the time periods specified in this Section 4 by reason of the failure of
such Holder to provide such information as (i) the Company may reasonably
request, with reasonable prior written notice, for use in the Shelf Registration
Statement or any Prospectus included therein to the extent the Company
reasonably determines that such information is required to be included therein
by applicable law, (ii) the NASD or the SEC may request in connection with such
Shelf Registration Statement or (iii) is required to comply with the agreements
of such Holder contained in the penultimate paragraph of Section 5 to the extent
compliance thereof is necessary for the Shelf Registration Statement to be
declared effective.

          (b)  The Company shall notify the Trustee within three Business Days
after each Registration Default (an "Event Date"). Any amounts of Additional
                                     ----------                             
Interest due pursuant to clause (i), (ii), (iii), (iv) or (v) of Section 4(a)
hereof will be payable in cash semi-annually on each June 1 and December 1 (to
the holders of record on the May 15 and November 15 immediately preceding such
dates), commencing with the first such date occurring after any such Additional
Interest commences to accrue.  The amount of Additional Interest will be
determined by multiplying the applicable Additional Interest rate by the
principal amount of the Notes making up the Registrable Securities, multiplied
by a fraction, the numerator of which is the number of days such Additional
Interest rate was applicable during such period (determined on the basis of a
360-day year comprised of twelve 30-day months and, in the case of a partial
month, the actual number of days elapsed), and the denominator of which is 360.

          5.   Registration Procedures
               -----------------------

          In connection with the filing of any Registration Statement pursuant
to Section 2 or 3 hereof, the Issuer shall effect such registrations to permit
the sale of the securities covered thereby in accordance with the intended
method or methods of disposition thereof, and pursuant thereto and in connection
with any Registration Statement filed by the Issuers hereunder the Issuers
shall:

          (a)  Prepare and file with the SEC on or prior to the Filing Date (in
the case of an Exchange Offer Registration Statement) or the Shelf Filing Date
(in the case of a Shelf Registration Statement), a Registration Statement or
Registration Statements as prescribed by Sections 2 or 3 hereof, and use its
best efforts to cause each such Registration Statement to become effective and
remain effective as provided herein; provided, however, that, if (1) such filing
                                     --------  -------                          
is pursuant to Section 3 hereof, or (2) a Prospectus contained in an Exchange
Offer

                                      14
<PAGE>
 
Registration Statement filed pursuant to Section 2 hereof is required to be
delivered under the Securities Act by any Par ticipating Broker-Dealer who seeks
to sell Exchange Securities during the Applicable Period, before filing any
Registration Statement or Prospectus or any amendments or supplements thereto,
the Issuers shall furnish to and afford the Holders of the Registrable
Securities covered by such Registration Statement or each such Participating
Broker-Dealer, as the case may be, one counsel selected by the Holders of a
majority in aggregate principal amount of the Registrable Securities (the
"Holders' Counsel"), counsel for such Participating Broker-Dealer and the
- -----------------                                                        
managing underwriters, if any, a reasonable opportunity to review copies of all
such documents (including copies of any documents to be incorporated by
reference therein and all exhibits thereto) proposed to be filed (in each case
at least five Business Days prior to such filing, or such later date as is
reasonable under the circumstances) and, in the event the Initial Purchasers are
participating in such Registration Statement, use their best efforts to reflect
in each such document, when filed with the SEC, such comments as the Initial
Purchasers or their counsel may reasonably propose.  The Issuers shall not file
any Registration Statement or Prospectus or any amendments or supplements
thereto if the Holders of a majority in aggregate principal amount of the
Registrable Securities covered by such Registration Statement and the Holders'
Counsel, or any such Participating Broker-Dealer and its counsel, as the case
may be, or the managing underwriters, if any, shall reasonably object.

          (b)  Prepare and file with the SEC such amendments and post-effective
amendments to each Shelf Registration Statement or Exchange Offer Registration
Statement, as the case may be, as may be necessary to keep such Registration
Statement continuously effective for the Effectiveness Period or the Applicable
Period, as the case may be; cause the related Prospectus to be supplemented by
any prospectus supplement required by applicable law, and as so supplemented to
be filed pursuant to Rule 424 promulgated under the Securities Act (as such Rule
may be amended from time to time, or any similar rule or regulation hereafter
adopted by the SEC); and comply with the provisions of the Securities Act and
the Exchange Act applicable to it with respect to the disposition of all
securities covered by such Registration Statement as so amended or in such
Prospectus as so supplemented and with respect to the subsequent resale of any
securities being sold by a Participating Broker-Dealer covered by any such
Prospectus.

          The Issuers shall be deemed not to have used their best efforts to
cause a Registration Statement to become effective or to keep a Registration
Statement effective during the Applicable Period or the Effectiveness Period, as
the case may be, if any of them voluntarily takes any action that would result
in selling Holders of the Registrable Securities covered thereby or
Participating Broker-Dealers seeking to sell Exchange Securities not being able
to sell such Registrable Securities or such Exchange Securities during that
period unless (i) such action is

                                      15
<PAGE>
 
required by applicable law or (ii) such action is taken by the Issuers in good
faith and for valid business reasons (not including avoidance of the Issuers'
obligations hereunder), including the acquisition or divestiture of assets.

          (c)  If (1) a Shelf Registration Statement is filed pursuant to
Section 3 hereof, or (2) a Prospectus contained in an Exchange Offer
Registration Statement filed pursuant to Section 2 hereof is required to be
delivered under the Securities Act by any Participating Broker-Dealer who seeks
to sell Exchange Securities during the Applicable Period, notify the selling
Holders of Registrable Securities and Holders' Counsel, or each such
Participating Broker-Dealer and their counsel, as the case may be, and the
managing underwriters, if any, promptly (but in any event within two Business
Days), (i) when a Prospectus or any prospectus supplement or post-effective
amendment has been filed, and, with respect to a Registration Statement or any
post effective amendment, when the same has become effective under the
Securities Act (including in such notice a written statement that any Holder
may, upon request, obtain, at the sole expense of the Issuers, one conformed
copy of such Registration Statement or post-effective amendment including
financial statements and schedules, documents incorporated or deemed to be
incorporated by reference therein and exhibits thereto), (ii) of the issuance by
the SEC or any state securities authority of any stop order suspending the
effectiveness of a Registration Statement or of any order preventing or
suspending the use of any preliminary Prospectus or the initiation of any
proceedings for that purpose, (iii) if at any time when a Prospectus is required
by the Securities Act to be delivered in connection with sales of the
Registrable Securities or resales of Exchange Securities by Participating
Broker-Dealers the representations and warranties of the Issuers contained in
any agreement (including any underwriting agreement) contemplated by Section
5(n) hereof, to the knowledge of the Company, cease to be true and correct in
all material respects, (iv) of the receipt by the Issuers of any notification
with respect to the suspension of the qualification or exemption from
qualification of a Registration Statement or any of the Registrable Securities
or the Exchange Securities to be sold by any Participating Broker-Dealer for
offer or sale in any jurisdiction, or the initiation or threatening of any
proceeding for such purpose, (v) of the happening of any event, or any
information becoming known that makes any statement made in such Registration
Statement or related Prospectus or any document incorporated or deemed to be
incorporated therein by reference untrue in any material respect or that
requires the making of any changes in or amendments or supplements to such
Registration Statement, Prospectus or documents so that, in the case of the
Registration Statement, it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, and that in the case of
the Prospectus, it will not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in

                                      16
<PAGE>
 
the light of the circumstances under which they were made, not misleading, (vi)
of any request by the SEC or any state securities authority for amendments or
supplements to the Registration Statement or Prospectus (including schedules and
exhibits thereto), and (vii) of the Company's determination that a post-
effective amendment to a Registration Statement would be appropriate.

          (d)  If (1) a Shelf Registration Statement is filed pursuant to
Section 3 hereof, or (2) a Prospectus contained in an Exchange Offer
Registration Statement filed pursuant to Section 2 hereof is required to be
delivered under the Securities Act by any Participating Broker-Dealer who seeks
to sell Exchange Securities during the Applicable Period, use their best efforts
to prevent the issuance of any order suspending the effectiveness of a
Registration Statement or of any order preventing or suspending the use of a
Prospectus or suspending the qualification (or exemption from qualification) of
any of the Registrable Securities or the Exchange Securities to be sold by any
Participating Broker-Dealer, for sale in any jurisdiction, and, if any such
order is issued, use their best efforts to obtain the withdrawal of any such
order at the earliest possible moment.

          (e)  If a Shelf Registration Statement is filed pursuant to Section 3
hereof and if requested by the managing underwriter or underwriters (if any),
the Holders of a majority in aggregate principal amount of the Registrable
Securities being sold in connection with an underwritten offering or any
Participating Broker-Dealer, (i) promptly incorporate in a prospectus supplement
or post-effective amendment such information as the managing underwriter or
underwriters (if any), their counsel, such Holders, Holders' Counsel, any
Participating Broker-Dealer or their counsel reasonably request to be included
therein and (ii) make all required filings of such prospectus supplement or such
post-effective amendment as soon as practicable after the Company has received
notification of the matters to be incorporated in such prospectus supplement or
post-effective amendment.

          (f)  If (1) a Shelf Registration Statement is filed pursuant to
Section 3 hereof, or (2) a Prospectus contained in an Exchange Offer
Registration Statement filed pursuant to Section 2 hereof is required to be
delivered under the Securities Act by any Participating Broker-Dealer who seeks
to sell Exchange Securities during the Applicable Period, furnish to each
selling Holder of Registrable Securities, Holders' Counsel and to each such
Participating Broker-Dealer who so requests and its counsel and each managing
underwriter, if any, at the sole expense of the Issuers, one conformed copy of
the Registration Statement or Registration Statements and each post-effective
amendment thereto, including financial statements and schedules, and, if
requested, all documents incorporated or deemed to be incorporated by reference
therein and all exhibits thereto.

          (g)  If (1) a Shelf Registration Statement is filed pursuant to
Section 3 hereof, or (2) a Prospectus contained in an Exchange Offer
Registration Statement filed pursuant to Section 2 hereof is required to be
delivered under the Securities Act by any Participating Broker-Dealer who seeks
to sell Exchange Securities during the Applicable Period, deliver to each
selling Holder of Registrable Securities and Holders' Counsel, or each such

Prospectus or Prospectuses (including each form of preliminary prospectus) and
each amendment or supplement thereto and any documents incorporated by reference
therein as such Persons may reasonably request; and, subject to the last
paragraph of this Section 5, the Issuers hereby consent to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders of Registrable Securities or each such Participating Broker-Dealer, as
the case may be, and the underwriters or agents, if any, and dealers, if any, in
connection with the offering and sale of the Registrable Securities covered by,
or the sale by Participating Broker-Dealers of the Exchange Securities pursuant
to, such Prospectus and any amendment or supplement thereto.

          (h)  Prior to any public offering of Registrable Securities or any
delivery of a Prospectus contained in the Exchange Offer Registration Statement
by any Participating Broker-Dealer who seeks to sell Exchange Securities during
the Applicable Period, use their best efforts to register and qualify, and to
cooperate with the selling Holders of Registrable Securities and Holders'
Counsel or each such Participating Broker-Dealer and its counsel, as the case

connection with the registration or qualification (or exemption from such
registration or qualification) of, such Registrable Securities for offer and
sale under the securities or Blue Sky laws of such jurisdictions within the
United States as any selling Holder, Participating Broker-Dealer, or the

Securities are offered other than through an underwritten offering, the Issuers
agree to cause the Issuers' counsel to perform Blue Sky investigations and file

5(h); keep each such registration or qualification (or exemption therefrom)
effective during the period such Registration Statement is required to be kept

Securities held by Participating Broker-Dealers or the Registrable Securities
covered by the applicable Registration Statement; provided, however, that none
                                                  --------  -------           
of the Issuers shall be required to (A) qualify generally to do business in any
jurisdiction where such Issuer is not then so qualified, (B) take any action
that would subject such Issuer to general service of process in any such

the seller or sellers thereof or the underwriter or underwriters, if any, to
consummate the disposition of such Registrable Securities, except as may be
required solely as a consequence of the nature of such selling Holder's
business, in which case the Issuers will cooperate in all reasonable respects
with the filing of such Registration Statement and the granting of such
approvals; provided, however, that none of the Issuers shall be required to (A)
           --------  -------                                                   
qualify generally to do business in any jurisdiction where such Issuer is not
then so qualified, (B) take any action that would subject it to general service
of process in any such jurisdiction where it is not then so subject or (C)
subject itself to taxation in excess of a nominal dollar amount in any such
jurisdiction where such Issuer is not then so subject.

          (k)  If (1) a Shelf Registration Statement is filed pursuant to
Section 3 hereof, or (2) a Prospectus contained in an Exchange Offer
Registration Statement filed pursuant to Section 2 hereof is required to be
delivered under the Securities Act by any Participating Broker-Dealer who seeks
to sell Exchange Securities during the Applicable Period, upon the occurrence of
any event contemplated by Section 5(c)(v), 5(c)(vi) or 5(c)(vii) hereof, as
promptly as practicable prepare and (subject to Section 5(a) hereof) file with
the SEC, at the sole expense of the Issuers, a supplement or post-effective
amendment to the Registration Statement or a supplement to the related
Prospectus or any document incorporated or deemed to be incorporated therein by
reference, or file any other required document so that, as thereafter delivered
to the purchasers of the Registrable Securities being sold thereunder or to the
purchasers of the Exchange Securities to whom such Prospectus will be delivered
by a Participating Broker-Dealer, any such Prospectus will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

                                      19

          (l)  Use its best efforts to cause the Registrable Securities covered
by a Registration Statement or the Exchange Securities, as the case may be, to
continue to be rated by the rating agencies which initially rated the
Securities, during the period the Registration Statement is required to remain
effective hereunder.

          (m)  Prior to the effective date of the first Registration Statement
relating to the Registrable Securities, (i) provide the Trustee with
certificates for the Registrable Securities in a form eligible for deposit with
The Depository Trust Company and (ii) obtain a CUSIP number for the Registrable
Securities.

          (n)  In connection with any underwritten offering of Registrable
Securities pursuant to a Shelf Registration Statement, enter into an
underwriting agreement as is customary in underwritten offerings of debt
securities similar to the Notes and take all other actions in order to expedite
or facilitate the registration or the disposition of such Registrable Securities
and, in such connection, (i) make such representations and warranties to, and
covenants with, the Holders of such Registrable Securities and the underwriters
with respect to the business of the Company and its subsidiaries (including any
acquired business, properties or entity, if applicable) and the Registration
Statement, Prospectus and documents, if any, incorporated or deemed to be
incorporated by reference therein, in each case, as are customarily made by
issuers to underwriters in underwritten offerings of debt securities similar to
the Notes, and confirm the same in writing if and when requested; (ii) obtain
the written opinions of counsel to the Issuers and written updates thereof in
form, scope and substance reasonably satisfactory to the managing underwriter or
underwriters, addressed to each Holder of such Registrable Securities and the
underwriters covering the matters customarily covered in opinions given in
underwritten offerings and such other matters as may be reasonably requested by
the managing underwriter or underwriters; (iii) obtain "comfort" letters and
updates thereof in form, scope and substance reasonably satisfactory to the
managing underwriter or underwriters from the independent certified public
accountants of the Company (and, if necessary, any other independent certified
public accountants of any subsidiary of the Company or of any business acquired
by the Company for which financial statements and financial data are, or are
required to be, included or incorporated by reference in the Registration
Statement), addressed to each selling Holder of such Registrable Securities and
the underwriters, such letters to be in customary form and covering matters of
the type customarily covered in "comfort" letters in connection with
underwritten offerings and such other matters as may be reasonably requested by
the managing underwriter or underwriters; (iv) if an underwriting agreement is
entered into, the same shall contain indemnification and contribution provisions
and procedures no less favorable than those set forth in Section 7 hereof (or
such other provisions and procedures acceptable to Holders of a majority in
aggregate

                                      20
<PAGE>
 
principal amount of Registrable Securities covered by such Registration
Statement and the managing underwriter or underwriters or agents) with respect
to all parties to be indemnified pursuant to said Section 7; and (v) deliver
such documents and certificates as may be reasonably requested by the Holders of
a majority in aggregate principal amount of all of the Registrable Securities
being sold and the managing underwriter or underwriters, if any, to evidence
compliance with any customary conditions contained in the underwriting agreement
or any other agreement entered into by the Issuers.  The above shall be done at
each closing under such underwriting agreement, or as and to the extent required
thereunder.

          (o)  If (1) a Shelf Registration Statement is filed pursuant to
Section 3 hereof, or (2) a Prospectus contained in an Exchange Offer
Registration Statement filed pursuant to Section 2 hereof is required to be
delivered under the Securities Act by any Participating Broker-Dealer who seeks
to sell Exchange Securities during the Applicable Period, make available for
inspection by any selling Holder of such Registrable Securities being sold, or
each such Participating Broker-Dealer, as the case may be, any underwriter
participating in any such disposition of Registrable Securities, if any, and any
attorney or accountant retained by any such selling Holder or each such
Participating Broker-Dealer, as the case may be, or underwriter (collectively,
the "Inspectors"), at the offices where normally kept, during business hours,
     ----------                                                              
all financial and other records, pertinent corporate documents and instruments
of the Company and its subsidiaries (collectively, the "Records") as shall be
                                                        -------              
reasonably necessary to enable them to exercise any applicable due diligence
responsibilities, and cause the officers, directors and employees of the Company
and its subsidiaries to supply all information reasonably requested by any such
Inspector in connection with such Registration Statement; provided, however,
                                                          --------  ------- 
that all information shall be kept confidential by each such Inspector, except
to the extent that (i) the disclosure of such Records is necessary to avoid or
correct a misstatement or omission in such Registration Statement, (ii) the
release of such Records is ordered pursuant to a subpoena or other order from a
court of competent jurisdiction, (iii) disclosure of such information is, in the
opinion of counsel for any Inspector, necessary or advisable in connection with
any action, claim, suit or proceeding, directly or indirectly, involving or
potentially involving such Inspector and arising out of, based upon, relating
to, or involving this Agreement, or any transactions contemplated hereby or
arising hereunder; provided, however, that prior notice be provided, to the
                   --------  -------                                       
Company as soon as practicable and in any event not less than three business
days before any such disclosure, of the potential disclosure of any information
by such Inspector pursuant to clause (ii) or this clause (iii) to permit the
Company to obtain a protective order (or waive the provisions of this Section
5(o)) and that such Inspector shall take such actions as are reasonably
necessary to protect the confidentiality of such information to the extent such
action is otherwise not inconsistent with an impairment of, or in

                                      21
<PAGE>
 
derogation of, the rights and interests of the Holders or any Inspector, or (iv)
the information in such Records has been made generally available to the public.
Each selling Holder of such Registrable Securities and each such Participating
Broker-Dealer will be required to agree that information obtained by it as a
result of such inspections shall be deemed confidential, shall be used only for
due diligence purposes pursuant to this Section 5(o) and shall not be used by it
as the basis for any market transactions in the securities of the Issuers unless
and until such information is made generally available to the public.  Each
selling Holder of such Registrable Securities and each such Participating
Broker-Dealer will be required to further agree that it will, upon learning that
disclosure of such Records is sought in a court of competent jurisdiction, give
notice to the Company and allow the Company to undertake appropriate action to
prevent disclosure of the Records deemed confidential at the Company's sole
expense.

          (p)  Provide an indenture trustee for the Registrable Securities or
the Exchange Securities, as the case may be, and cause the Indenture or the
trust indenture provided for in Section 2(a) hereof, as the case may be, to be
qualified under the TIA not later than the effective date of the Exchange Offer
Registration Statement or the first Registration Statement relating to the
Registrable Securities; and in connection therewith, cooperate with the trustee
under any such indenture and the Holders of the Registrable Securities, to
effect such changes to such indenture as may be required for such indenture to
be so qualified in accordance with the terms of the TIA; and execute, and use
its best efforts to cause such trustee to execute, all documents as may be
required to effect such changes, and all other forms and documents required to
be filed with the SEC to enable such indenture to be so qualified in a timely
manner.

          (q)  Use their best efforts to comply with all applicable rules and
regulations of the SEC and make generally available to its securityholders
earnings statements satisfying the provisions of Section 11(a) of the Securities
Act and Rule 158 thereunder (as such Rule may be amended from time to time, or
any similar rule or regulation hereafter adopted by the SEC) no later than 45
days after the end of any 12-month period (or 90 days after the end of any 12-
month period if such period is a fiscal year) (i) commencing at the end of any
fiscal quarter in which Registrable Securities are sold to underwriters in a
firm commitment or best efforts underwritten offering and (ii) if not sold to
underwriters in such an offering, commencing on the first day of the first
fiscal quarter of the Company after the effective date of a Registration
Statement, which statements shall cover said 12-month periods.

          (r)  Upon consummation of an Exchange Offer or a Private Exchange,
obtain an opinion of counsel to the Issuers, in a form customary for
underwritten transactions, addressed to the Trustee for the benefit of all
Holders of Registrable Securities

                                      22
<PAGE>
 
participating in the Exchange Offer or the Private Exchange, as the case may be,
that the Exchange Securities or Private Exchange Securities, as the case may be,
and the related indenture constitute legal, valid and binding obligations of the
Issuers, enforceable against the Issuers in accordance with their respective
terms, subject to customary exceptions and qualifications.

          (s)  If the Exchange Offer or a Private Exchange is to be consummated,
upon delivery of the Registrable Securities by Holders to the Company (or to
such other Person as directed by the Company) in exchange for the Exchange
Securities or the Private Exchange Securities, as the case may be, the Company
shall mark, or cause to be marked, on such Registrable Securities that such
Registrable Securities are being canceled in exchange for the Exchange
Securities or the Private Exchange Securities, as the case may be; in no event
shall such Registrable Securities be marked as paid or otherwise satisfied.

          (t)  If a Shelf Registration Statement is filed pursuant to Section 3
hereof, a reasonable time prior to the filing of any document which is to be
incorporated by reference into a Registration Statement or Prospectus after the
initial filing of a Shelf Registration Statement, provide a reasonable number of
copies of such document to the Initial Purchasers on behalf of the Holders of
Registrable Securities covered thereby, and make available such of the
representatives of the Company and its subsidiaries as shall be reasonably
requested by such Holders or the Initial Purchasers on behalf of such Holders
for discussion of such document.

          (u)  Cooperate with each seller of Registrable Securities covered by
any Registration Statement, Holders' Counsel and each underwriter, if any,
participating in the disposition of such Registrable Securities and its counsel
in connection with any filings required to be made with the NASD (including,
without limitation, engaging and cooperating with a "qualified independent
underwriter" if required by the Rules of Fair Practice and the By-Laws of the
NASD).

          (v)  Use its reasonable best efforts to take all other steps necessary
or advisable to effect the registration of the Exchange Securities and/or
Registrable Securities covered by a Registration Statement contemplated hereby.

          The Company may require each seller of Registrable Securities or
Participating Broker-Dealer as to which any registration is being effected to
furnish to the Company such information regarding such seller or Participating
Broker-Dealer and the distribution of such Registrable Securities or Exchange
Securities to be sold by such Participating Broker-Dealer, as the case may be,
as the Company may, from time to time, reasonably request, including, without
limitation, a written representation to the Issuers (which may be contained in
the letter of transmittal contemplated by the Exchange Offer Registration

                                      23
<PAGE>
 
Statement or Shelf Registration Statement, as applicable) stating (A) that it is
not an affiliate of any of the Issuers, within the meaning of the Securities
Act, (B) that it is acquiring the Exchange Securities in the ordinary course of
business, (C) the amount of Registrable Securities held by such Holder prior to
the Exchange Offer and the amount of Registrable Securities owned by such Holder
to be exchanged in the Exchange Offer, and (D) if such Holder is not a broker-
dealer, that such Holder is not engaged in, and does not intend to engage in,
and has no arrangement or understanding with any Person to participate in, a
distribution of the Exchange Securities to be issued, within the meaning of the
Securities Act and if such Holder is a broker-dealer, that it will receive
Exchange Securities for its own account in exchange for Registrable Securities
that were acquired as a result of market-making activities or other trading
activities and that it will be required to acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities.  The
Company may exclude from such registration the Registrable Securities of any
seller or Participating Broker-Dealer who fails to furnish such information or
to make such representations within a reasonable time after receiving such
request.  Each seller as to which any registration pursuant to a Shelf
Registration Statement is being effected agrees to furnish promptly to the
Company all information required to be disclosed in order to make the
information previously furnished to the Company by such seller not materially
misleading.

          Each Holder of Registrable Securities and each Participating Broker-
Dealer will agree by acquisition of such Registrable Securities or Exchange
Securities to be sold by such Participating Broker-Dealer, as the case may be,
that upon actual receipt of any notice from the Company of the happening of any
event of the kind described in Section 5(c)(ii), 5(c)(iii), 5(c)(iv), 5(c)(v),
5(c)(vi) or 5(c)(vii) hereof, such Holder will forthwith discontinue disposition
of such Registrable Securities covered by such Registration Statement or
Prospectus or Exchange Securities to be sold by such Holder or Participating
Broker-Dealer, as the case may be, until such Holder's or Participating Broker-
Dealer's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 5(k) hereof, or until it is advised in writing (the
"Advice") by the Company that the use of the applicable Prospectus may be
- -------                                                                  
resumed, and has received copies of any amendments or supplements thereto.  If
so directed by the Company, each Holder will deliver to the Company all copies
(other than permanent file copies then in such Holder's possession) of the
Prospectus covering the Registrable Securities that was current at the time of
receipt of such notice.  In the event the Company shall give any such notice,
each of the Effectiveness Period and the Applicable Period shall be extended by
the number of days during such periods from and including the date of the giving
of such notice to and including the date when each seller of Registrable
Securities covered by such Registration Statement or Exchange Securities to be
sold by such Participating Broker-Dealer, as the case may be, shall have

                                      24
<PAGE>
 
received (x) the copies of the supplemented or amended Prospectus contemplated
by Section 5(k) hereof or (y) the Advice.

          6.   Registration Expenses
               ---------------------

          (a) All fees and expenses incident to the performance of or compliance
with this Agreement by the Issuers shall be borne jointly and severally by the
Issuers whether or not the Exchange Offer Registration Statement or a Shelf
Registration Statement is filed or becomes effective, including, without
limitation, (i) all registration and filing fees (including, without limitation,
(A) fees with respect to filings required to be made with the NASD in connection
with an underwritten offering and (B) fees and expenses of compliance with state

disbursements of counsel in connection with Blue Sky qualifications of the
Registrable Securities or Exchange Securities and determination of the
eligibility of the Registrable Securities or Exchange Securities for investment
under the laws of such jurisdictions (x) where the holders of Registrable
Securities are located, in the case of the Exchange Securities, or (y) as
provided in Section 5(h) hereof, in the case of Registrable Securities or
Exchange Securities to be sold by a Participating Broker-Dealer during the
Applicable Period)), (ii) printing expenses, including, without limitation,
expenses of printing certificates for Registrable Securities or Exchange
Securities in a form eligible for deposit with The Depository Trust Company and
of printing prospectuses if the printing of prospectuses is requested by the
managing underwriter or underwriters, if any, by the Holders of a majority in
aggregate principal amount of the Registrable Securities included in any
Registration Statement or in respect of Registrable Securities or Exchange
Securities to be sold by any Participating Broker-Dealer during the Applicable
Period, as the case may be, (iii) messenger, telephone and delivery expenses,
(iv) fees and disbursements of counsel for the Issuers and reasonable fees and
disbursements of Holders' Counsel (subject to the provisions of Section 6(b)
hereof), (v) fees and disbursements of all independent certified public
accountants referred to in Section 5(n)(iii) hereof (including, without
limitation, the expenses of any special audit and "comfort" letters required by
or incident to such performance), (vi) rating agency fees, (vii) Securities Act
liability insurance, if the Company desires such insurance, (viii) fees and
expenses of all other Persons retained by the Company, (ix) internal expenses of
the Company (including, without limitation, all salaries and expenses of
officers and employees of the Issuers performing legal or accounting duties),
(x) the expense of any annual audit, (xi) the fees and expenses incurred in
connection with the listing of the securities to be registered on any securities
exchange, if applicable, and (xii) the expenses relating to printing, word

                                      25
<PAGE>
 
          (b)  The Issuers shall reimburse the Holders of the Registrable
Securities being registered in a Shelf Registration Statement for the reasonable
fees and disbursements of Holders' Counsel (in addition to appropriate local
counsel) and other reasonable out-of-pocket expenses of such Holders of
Registrable Securities incurred in connection with the registration and sale of
the Registrable Securities.

          7.   Indemnification
               ---------------

          (a)  The Issuers jointly and severally agree to indemnify and hold
harmless each Holder of Registrable Securities (including each Initial
Purchaser, if such Initial Purchaser holds Registrable Securities or Private
Exchange Securities for its own account) and each Participating Broker-Dealer
selling Exchange Securities during the Applicable Period, the officers and
directors of each such Person, and each Person, if any, who controls any such
Person within the meaning of either Section 15 of the Securities Act or Section
20 of the Exchange Act (each, a "Participant"), from and against any and all
                                 -----------                                
losses, claims, damages and liabilities (including, without limitation, and
subject to Section 7(c) below, any legal fees and other expenses reasonably
incurred by such Participant in connection with preparing to defend, defending,
investigating or appearing as a third-party witness in connection with any such
action or claim), joint or several, caused by, arising out of or based upon any
untrue statement or alleged untrue statement of a material fact contained in any
Registration Statement (or any amendment thereto) or Prospectus (as amended or
supplemented if the Issuers shall have furnished any amendments or supplements
thereto), or caused by, arising out of or based upon any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus, in the
light of the circumstances under which they were made) not misleading, except
insofar as such losses, claims, damages, liabilities or expenses are caused by
any untrue statement or omission or alleged untrue statement or omission made in
any Registration Statement or Prospectus, or amendment or supplement thereto,
made in reliance upon and in conformity with information relating to any
Participant furnished to the Company in writing by such Participant expressly
for use therein; provided, however, that the Issuers shall not be required to
                 --------  -------                                           
indemnify any such Person if such untrue statement or omission or alleged untrue
statement or omission was contained or made in any preliminary prospectus and
corrected in the Prospectus or any amendment or supplement thereto and the
Prospectus does not contain any other untrue statement or omission or alleged
untrue statement or omission of a material fact that was the subject matter of
the related proceeding and any such loss, claim, damage, liability or expense
suffered or incurred by the Participants resulted from any action, claim or suit
by any Person who purchased Registrable Securities or Exchange Securities which
are the subject thereof from such Participant and it is established in the
related proceeding that such Participant failed to deliver or provide a copy of
the Prospectus

                                      26
<PAGE>
 
(as amended or supplemented) to such Person with or prior to the confirmation of
the sale of such Registrable Securities or Exchange Securities sold to such
Person if required by applicable law, unless such failure to deliver or provide
a copy of the Prospectus (as amended or supplemented) was a result of
noncompliance by the Issuers with Section 5 hereof.

          (b)  The Issuers may require, as a condition to including any
Registrable Securities or Exchange Securities in any Registration Statement
filed pursuant to this Agreement that each Participant shall agree, severally
and not jointly, to indemnify and hold harmless the Issuers, their respective
officers and directors, and each Person who controls the Issuers within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the foregoing indemnity from the Issuers to each Participant,
but only with reference to information relating to such Participant furnished to
the Company in writing by such Participant expressly for use in any Registration
Statement or Prospectus or any amendment or supplement thereto.  The liability
of any Participant under such agreement shall in no event exceed the proceeds
received by such Participant from sales of Registrable Securities or Exchange
Securities giving rise to such obligations.

          (c)  If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be instituted or asserted
against any Person in respect of which indemnity may be sought pursuant to
either of paragraph (a) or (b) above, such Person (the "Indemnified Person")
                                                        ------------------  
shall promptly notify the Person against whom such indemnity may be sought (the
"Indemnifying Person") in writing; provided, however, that the failure to so
 -------------------               --------  -------                        
notify the Indemnifying Person shall not relieve it of any obligation or
liability which it may have hereunder or otherwise (unless and only to the
extent that such failure directly results in the loss or compromise of any
material rights or defenses by the Indemnifying Person and the Indemnifying
Person was not otherwise aware of such action or claim).  The Indemnifying
Person, upon request of the Indemnified Person, shall assume the defense
thereof, including the employment of counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may reasonably designate in such proceeding and shall pay
the reasonable fees and expenses actually incurred by such counsel related to
such action or proceeding.  In any such action or proceeding, any Indemnified
Person shall have the right to retain its own counsel, but the fees and expenses
of such counsel shall be at the expense of such Indemnified Person unless (i)
the Indemnifying Person and the Indemnified Person shall have mutually agreed in
writing to the contrary, (ii) the Indemnifying Person shall have failed within a
reasonable period of time to retain counsel reasonably satisfactory to the
Indemnified Person or (iii) the named parties to any such proceeding (including
any impleaded parties) include both the Indemnifying Person and the Indemnified
Person or any affiliate of either and representation of both parties by the same
counsel would be inappropriate due to

                                      27
<PAGE>
 
actual or potential differing interests between them.  It is understood that,
unless there exists a conflict among Indemnified Persons, the Indemnifying
Person shall not, in connection with any one such proceeding or separate but
substantially similar related proceedings in the same jurisdiction, be liable
for the fees and expenses of more than one separate firm (in addition to any
appropriate local counsel) for all Indemnified Persons, and that all such
reasonable fees and expenses shall be reimbursed promptly after receipt of the
invoice therefor as they are incurred.  Any such separate firm for the
Participants and such control Persons of Participants shall be designated in
writing by Participants who sold a majority in aggregate principal amount of
Registrable Securities and Exchange Securities sold by all such Participants and
any such separate firm for the Issuers, their respective directors, their
respective officers and such control Persons of the Issuers shall be designated
in writing by the Company.  The Indemnifying Person shall not be liable for any
settlement of any proceeding effected without its prior written consent (which
consent shall not be unreasonably withheld), but if settled with such consent or
if there be a final judgment for the plaintiff for which the Indemnified Person
is entitled to indemnification pursuant to this Agreement, the Indemnifying
Person agrees to indemnify and hold harmless each Indemnified Person from and
against any loss or liability by reason of such settlement or judgment.  No
Indemnifying Person shall, without the prior written consent of the Indemnified
Persons (which consent shall not be unreasonably withheld), effect any
settlement or compromise of any pending or threatened proceeding in respect of
which any Indemnified Person is or could have been a party, or indemnity could
have been sought hereunder by such Indemnified Person, unless such settlement or
compromise includes an unconditional written release of such Indemnified Person,
in form and substance reasonably satisfactory to such Indemnified Person, from
all liability on claims that are the subject matter of such proceeding or such
Indemnifying Person indemnifies the Indemnified Person in writing and posts a
bond for an amount equal to the maximum liability for all such claims as
contemplated above.

          (d)  If the indemnification provided for in paragraphs (a) and (b) of
this Section 7 is for any reason unavailable to (other than by reason of
exceptions provided therein), or insufficient to hold harmless, an Indemnified
Person in respect of any losses, claims, damages or liabilities (or actions in
respect thereof) referred to therein, then each Indemnifying Person under such
paragraphs, in lieu of indemnifying such Indemnified Person thereunder and in
order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect
(i) the relative benefits received by the Indemnifying Person or Persons on the
one hand and the Indemnified Person or Persons on the other hand from the
offering of the Securities or (ii) if the allocation provided by the foregoing
clause (i) is not permitted by applicable law, not only

                                      28
<PAGE>
 
such relative benefits but also the relative fault of the Indemnifying Person or
Persons on the one hand and the Indemnified Person or Persons on the other hand
in connection with the statements or omissions or alleged statements or
omissions that resulted in such losses, claims, damages or liabilities (or
actions in respect thereof) as well as any other relevant equitable
considerations.  The relative benefits received by the Issuers on the one hand
and the Participants on the other hand shall be deemed to be in the same
proportion as the total proceeds from the offering of the Securities (net of
discounts and commissions but before deducting expenses) received by the Issuers
bears to the total proceeds received by such Participant from the sale of
Registrable Securities or Exchange Securities, as the case may be.  The relative
fault of the parties shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Issuers on the one hand or such Participant or such other
Indemnified Person, as the case may be, on the other hand, the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission, and any other equitable considerations appropriate
in the circumstances.

          (e)  The parties agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
                                                           --- ----           
(even if the Participants were treated as one entity for such purpose) or by any
other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph.  The amount
paid or payable by an Indemnified Person as a result of the losses, claims,
damages or liabilities (or actions in respect thereof) referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal fees or other expenses reasonably
incurred by such Indemnified Person in connection with defending or
investigating any such action or claim.  Notwithstanding the provisions of this
Section 7, in no event shall a Participant be required to contribute any amount
in excess of the amount by which proceeds received by such Participant from
sales of Registrable Securities or Exchange Securities, as the case may be,
exceeds the amount of any damages that such Participant has otherwise been
required to pay or has paid by reason of such untrue or alleged untrue statement
or omission or alleged omission.  No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.  The amount paid or payable by any party as a
result of this Section 7(e) shall be deemed to include any legal or other
expenses reasonably incurred by such party in connection with investigating,
preparing to defend or defending such claim.

          (f)  The indemnity and contribution agreements contained in this
Section 7 will be in addition to any liability

                                      29
<PAGE>
 
which the Indemnifying Persons may otherwise have to the Indemnified Persons
referred to above.

          8.   Rules 144 and 144A
               ------------------

          The Issuers covenant to file with the Trustee copies of the annual
reports and of the information, documents and other reports which the Issuers
may be required to file with the SEC pursuant to Section 13 or Section 15(d) of
the Exchange Act, within 15 days after the Issuers are required to file the same
with the SEC.  If, during any period in which Registrable Securities are
outstanding, the Issuers are not obligated to file annual reports, documents or
other reports with the SEC pursuant to Section 13 or 15(d) of the Exchange Act,
the Issuers will furnish to the Trustee the same such annual reports documents
or other reports as if the Issuers were so subject.  The Issuers further
covenant, for so long as any Registrable Securities remain outstanding, to make
available to any Holder or beneficial owner of Registrable Securities in
connection with any sale thereof and any prospective purchaser of such
Registrable Securities from such Holder or beneficial owner, the information
required by Rule 144A(d)(4) under the Securities Act in order to permit resales
of such Registrable Securities pursuant to Rule 144A, unless the Issuers are
then subject to Section 13 or 15(d) of the Exchange Act and reports filed
thereunder satisfy the information requirements of Rule 144A(d)(4) as then in
effect.

          9.   Underwritten Registrations
               --------------------------

          If any of the Registrable Securities covered by any Shelf Registration
Statement are to be sold in an underwritten offering, the investment banker or
investment bankers and manager or managers that will manage the offering will be
selected by the Holders of a majority in aggregate principal amount of such
Registrable Securities included in such offering and shall be reasonably
acceptable to the Company.

          No Holder of Registrable Securities may participate in any
underwritten registration hereunder unless such Holder (a) agrees to sell such
Holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements, and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements.

          10.  Miscellaneous
               -------------

          (a)  No Inconsistent Agreements.  The Issuers have not, as of the date
               --------------------------                                       
hereof, and the Issuers shall not after the date of this Agreement, enter into
any agreement with respect to any of its securities that is inconsistent with
the rights granted to the Holders of Registrable Securities in this Agreement or
otherwise conflicts with the provisions hereof.  The rights granted to the
Holders hereunder do not in any way conflict with

                                      30
<PAGE>
 
and are not inconsistent with the rights granted to the holders of the Issuers'
other issued and outstanding securities under any such agreements.  The Issuers
have not entered and will not enter into any agreement with respect to any of
their securities which will grant to any Person "piggy-back" registration rights
with respect to a Registration Statement.

          (b)  Adjustments Affecting Registrable Securities.  The Issuers shall
               --------------------------------------------                    
not, directly or indirectly, take any action with respect to the Registrable
Securities as a class that would adversely affect the ability of the Holders of
Registrable Securities to include such Registrable Securities in a registration
undertaken pursuant to this Agreement.

          (c)  Amendments and Waivers.  The provisions of this Agreement may not
               ----------------------                                           
be amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, otherwise than with the prior written
consent of (A) the Holders of not less than a majority in aggregate principal
amount of the then outstanding Registrable Securities and (B) in circumstances
that would adversely affect the Participating Broker-Dealers, the Participating
Broker-Dealers holding not less than a majority in aggregate principal amount of
the Exchange Securities held by all Participating Broker-Dealers; provided,
                                                                  -------- 
however, that Section 7 hereof and this Section 10(c) may not be amended,
- -------                                                                  
modified or supplemented without the prior written consent of each Holder and
each Participating Broker-Dealer (including any person who was a Holder or
Participating Broker-Dealer of Registrable Securities or Exchange Securities, as
the case may be, disposed of pursuant to any Registration Statement).
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
Holders of Registrable Securities whose securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect, impair,
limit or compromise the rights of other Holders of Registrable Securities may be
given by Holders of at least a majority in aggregate principal amount of the
Registrable Securities being sold by such Holders pursuant to such Registration
Statement.

          (d)  Notices.  All notices and other communications (including without
               -------

Securities, each in definitive form, without interest coupons, registered in
such names and in such denominations as you may request in writing at least two
full business days prior to the Closing Date, in the principal amounts
corresponding to the aggregate principal amount of the Securities sold to
institutional "accredited investors" (as defined in Section 5 below) who are not

           ---------------------                                            
Issuers to you for your respective accounts against payment by you of the
purchase price therefor by wire transfer of immediately available funds to an
account specified by the Company by written notice to the Initial Purchasers,
for the purchase price of the Securities being sold by the Issuers in
Philadelphia, Pennsylvania, at 9:30 A.M., Philadelphia time, on December 5,
1996, or at such other time, date and place as you and the Company may agree
upon in writing, such time and date being herein called the "Closing Date."  The

Initial Purchasers and the Company have determined that it is not feasible to
close at an earlier date.  The Issuers agree to reimburse the Initial Purchasers
by offset against the purchase price for the incremental cost of providing
immediately available funds over the cost of obtaining New York Clearing House
funds.

          (b)  Certificates for the Securities so to be delivered will be in
good delivery form, and will be made available for checking and packaging in
Philadelphia, Pennsylvania, at least 24 hours prior to the Closing Date.

          (c)  It is understood that each certificate evidencing Securities
shall bear the following legend, until in the opinion of counsel to the Issuers
such legend is no longer necessary or

                                      17

advisable because such Securities are no longer subject to the restrictions on
transfer described therein:

          THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF
     1933, AS AMENDED (THE "SECURITIES ACT") OR ANY STATE SECURITIES LAWS AND
     ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE
     FOLLOWING SENTENCE.  BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS
     THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A
     UNDER THE SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL INVESTOR THAT IS AN
     "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7) UNDER
     THE SECURITIES ACT) (AN "INSTITUTIONAL ACCREDITED INVESTOR");  (2) AGREES
     FOR THE BENEFIT OF RADNOR HOLDINGS CORPORATION THAT IT WILL NOT, WITHIN
     THREE YEARS AFTER THE LATER OF THE ORIGINAL ISSUANCE OF THIS SECURITY OR
     THE LAST DATE ON WHICH THIS SECURITY WAS HELD BY AN AFFILIATE OF RADNOR
     HOLDINGS CORPORATION, RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A)
     TO RADNOR HOLDINGS CORPORATION OR ANY SUBSIDIARY THEREOF, (B) TO A
     QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE
     SECURITIES ACT, (C) TO AN INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO
     SUCH TRANSFER, FURNISHES TO THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN
     REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF
     THIS SECURITY (THE FORM OF WHICH CAN BE OBTAINED FROM THE TRUSTEE), (D)
     PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
     SECURITIES ACT (IF AVAILABLE) OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION
     STATEMENT UNDER THE SECURITIES ACT,  SUBJECT IN EACH OF THE FOREGOING CASES
     TO ANY REQUIREMENT OF LAW THAT THE DISPOSITION OF SUCH HOLDER'S PROPERTY OR
     THE PROPERTY OF SUCH HOLDER'S ACCOUNT AT ALL TIMES BE WITHIN ITS CONTROL
     AND TO COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS; AND (3) AGREES
     THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A
     NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  IN CONNECTION WITH ANY
     TRANSFER OF ANY CERTIFICATED SECURITY WITHIN THREE YEARS AFTER THE LATER OF
     THE ORIGINAL ISSUANCE OF THE SECURITY OR THE LAST DATE ON WHICH SUCH
     CERTIFICATED SECURITY WAS HELD BY AN AFFILIATE OF RADNOR HOLDINGS
     CORPORATION, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE
     REVERSE OF SUCH CERTIFICATED SECURITY RELATING TO THE MANNER OF SUCH
     TRANSFER AND SUBMIT SUCH CERTIFICATED SECURITY TO THE TRUSTEE.  IF ANY
     PROPOSED TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR, THE HOLDER
     MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE AND RADNOR HOLDINGS
     CORPORATION, SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS
     EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS
     BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT
     TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OR APPLICABLE STATE
     SECURITIES LAWS.  THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE
     TO REFUSE TO REGISTER ANY

                                                                ----         
     the meaning of Rule 144A under the Securities Act in transactions meeting
     the requirements of Rule 144A and to a limited number of institutional
     "accredited investors" (as defined in Rule 501(a)(1), (2), (3) or (7) under
     the Securities Act) that, prior to their purchase of the Securities,
     deliver to such Initial Purchaser a letter containing the representations
     and agreements set forth in Exhibit A hereto;
                                 ---------        

          (b)  Such Initial Purchaser has not and will not offer or sell the

     including but not limited to, the methods described in Rule 502(c) under
     the Securities Act;

          (c)  Such Initial Purchaser agrees that, prior to or simultaneously
     with the confirmation of sale to any purchaser of any of the Securities
     purchased by such Initial Purchaser from the Issuers pursuant hereto,
     provided that the Issuers have complied with their obligations under
     Section 6(a) hereof, such Initial Purchaser shall furnish to that purchaser
     a copy of the Final Offering Memorandum (and any amendment thereof or
     supplement thereto that the Issuers shall have furnished to such Initial
     Purchaser prior to the date of such confirmation of sale); and

          (d)  Such Initial Purchaser understands that the Issuers, and, for
     purposes of the opinions to be delivered to the Initial Purchasers pursuant
     to Section 7 hereof, Duane, Morris & Heckscher, counsel to the Issuers, and
     Milbank, Tweed, Hadley & McCloy, counsel to the Initial Purchasers, will
     rely upon the accuracy and truth of the foregoing representations and such
     Initial Purchaser hereby consents to such reliance.

     Purchasers reasonably object;

          (c) If, at any time prior to the completion of the distribution of the
     Securities by the Initial Purchasers, any event occurs as a result of which
     the Final Offering Memorandum as then amended or supplemented would include
     any untrue statement of a material fact, or omit to state a material fact
     necessary to make the statements therein, in the light of the circumstances
     under which they were made, not misleading, or if for any other reason it
     is necessary at any time to amend or supplement the Final Offering
     Memorandum to comply with applicable law, the Issuers will promptly notify
     the Initial Purchasers thereof and will prepare, at the expense of the
     Issuers, an amendment or supplement to the Final Offering Memorandum that

     none of the Issuers shall be obligated to file any general consent to
     service of process or to qualify as a foreign corporation or as a dealer in

     Securities Act) which could be integrated with the sale of the Securities
     in a manner which would require the registration under the Securities Act
     of such Securities;

          (f) Except following the effectiveness of the Exchange Offer
     Registration Statement, not to solicit any offer to buy or offer to sell
     the Securities by means of any form of general solicitation or general

     Act) or in any manner involving a public offering within the meaning of
     Section 4(2) of the Securities Act;

          (g) While any of the Securities remain outstanding, to make available,

     of the Company and certain of the Issuers, the Securities, the Final
     Offering Memorandum, the Indenture, the Registration Rights Agreement and
     other related matters as the Initial Purchasers may reasonably request.

          (j)  (i)  The Initial Purchasers shall have received on each of the
     date hereof and the Closing Date a letter, dated the date hereof or the
     Closing Date, as the case may be, in form and substance satisfactory to

     or any material change in the short-term debt, of the Company or any of the
     Guarantors nor any material change otherwise than as set forth or
     contemplated in the Final Offering Memorandum, the effect of which, in any
     such case described in clause (i) or (ii), is in the judgment of the
     Initial Purchasers so material and adverse as to make it impracticable or
     inadvisable to proceed with the offering or the delivery of the Securities
     on the terms and in the manner contemplated in the Final Offering
     Memorandum.

          (l)  Subsequent to the execution and delivery of this Agreement (i)

                                       25
<PAGE>
 
     have occurred any material adverse change in the financial or securities
     markets in the United States or in political, financial or economic
     conditions in the United States or any outbreak or material escalation of
     hostilities or other calamity or crisis, the effect of which is such as to
     make it, in the reasonable judgment of the Initial Purchasers,
     impracticable to market the Securities or to enforce contracts for the
     resale of Securities and (iii) no event shall have occurred resulting in
     (A) trading in securities generally on the New York Stock Exchange, the
     American Stock Exchange or on any automated quotation system or over-the-
     counter market regulated by the NASD being suspended or materially limited

     such exchange, system or market) or minimum or maximum prices being
     generally established on such exchange, or (B) additional material
     governmental restrictions, not in force on the date of this Agreement,
     being imposed upon trading in securities generally by such exchange or by
     order of the Commission or any court or other governmental authority or (C)
     a general banking moratorium being declared by either Federal or New York
     authorities.

          (m)  The Issuers shall have furnished or caused to be furnished to the
     Initial Purchasers at the Closing Date any additional certificates signed
     by the secretary or by the chief executive officer and the chief financial
     officer of the Company or any Guarantor, on behalf of the Issuers,
     satisfactory to the Initial Purchasers as to such matters as the Initial
     Purchasers may reasonably request.

          (n)  The Issuers and the Initial Purchasers shall have entered into
     the Registration Rights Agreement.

          (o) The Credit Agreements shall have been executed and delivered by
     each of the parties thereto and shall be in full force and effect and the
     Company shall have availability under the Credit Agreements to borrow the
     amount necessary to consummate the transactions contemplated by the Final
     Offering Memorandum.

          (p) All of the elements of the StyroChem Acquisition and the Other
     Financings to be consummated on or prior to the Closing Date shall have
     been consummated, including without limitation the execution of the non-
     competition agreement between the Company and Richard Davidovich and the
     execution of the consulting agreement between the Company and Richard
     Davidovich.

          (q) The Company shall have consummated the J.R. Cup Acquisition and
     shall have entered into such agreements in connection therewith as are
     described in each Memorandum, including without limitation five-year
     extensions of a sales agent agreement, an equipment use agreement and a
     license

                                       26

     relating to certain trademark rights, a sublease on manufacturing and
     warehouse facilities and a settlement of a dispute relating to certain
     disability claims.

          (r) The Notes shall have been designated for trading on PORTAL.

          (s) All legal opinions and accountants' "comfort" letters received in
     connection with the Acquisitions, whose form and substance shall have been
     determined by the Company, shall be addressed to, or permit reliance on by,
     and delivered to the Initial Purchasers.

          8.   Indemnity and Contribution.  (a)  Each of the Issuers jointly and
               --------------------------                                       
severally agree to indemnify and hold harmless each Initial Purchaser, its
officers, authorized representatives and directors (such officers, authorized
representatives and directors of the Initial Purchasers being referred to in
this Section 8(a) as "affiliated persons") and each person, if any, who controls
                      ------------------                                        
the Initial Purchasers within the meanings of Section 15 of the Securities Act
or Section 20 of the Exchange Act, against any losses, claims, damages or
liabilities ("Losses"), joint or several, to which the Initial Purchasers or any
              ------                                                            
such controlling or affiliated person may become subject, under the Securities
Act, the Exchange Act, any other Federal or state statutory law or regulation,
at common law or otherwise, insofar as such Losses (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in any Memorandum, or any amendment or
supplement thereto, or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
made therein, in the light of the circumstances under which they were made, not
misleading, and will reimburse the Initial Purchasers and such controlling or
affiliated persons for any legal or other expenses reasonably incurred by the
Initial Purchasers and such controlling or affiliated person in connection with
investigating, preparing to defend, defending or appearing as a third-party
witness in connection with any such action or claim; provided, however, that
                                                     --------  -------      
none of the Issuers shall be liable in any such case to the extent that such
Losses arise out of or are based upon an untrue statement or alleged untrue
statement or omission or alleged omission relating to the Initial Purchasers
made in any Memorandum, or any amendment or supplement in reliance upon and in
conformity with written information furnished to the Issuers by Alex. Brown &
Sons Incorporated expressly for use therein; provided, further, that the
                                             --------  -------          
indemnity obligations arising under this Section 8(a) with respect to the
Preliminary Offering Memorandum shall not inure to the Initial Purchasers'
benefit or that of any such controlling or affiliated person if the person
asserting any such Losses purchased the Securities from the Initial Purchasers
and if a copy (provided that the Issuers have complied with their obligations
under Section 5(a) hereof) of the Final Offering

                                       27
<PAGE>
 
Memorandum was not sent or given by the Initial Purchasers or on the Initial
Purchasers' behalf to such person at or prior to the written confirmation of the
sale of the Securities to such person, and if the Final Offering Memorandum
would have cured the untrue statement or omission giving rise to such Losses.

          The indemnity agreement in this Section 8(a) shall be in addition to
any liability which any of the Issuers may otherwise have.

          (b) The Initial Purchasers will indemnify and hold harmless each
Issuer, its officers, authorized representatives and directors (such officers,
authorized representatives and directors of the Issuers being referred to in
this Section 8(b) as "affiliated persons") and each person, if any, who controls
                      ------------------                                        
any of the Issuers within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act, against any Losses to which the Issuers may
become subject, under the Securities Act, the Exchange Act, any Federal or state
statutory law or regulation, at common law or otherwise, insofar as such Losses
(or actions in respect thereof) arise out of or are based upon (i) any untrue
statement or alleged untrue statement made by the Initial Purchasers in Section
4 hereof or (ii) an untrue statement or alleged untrue statement of a material
fact contained in any Memorandum, or any amendment or supplement thereto, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in any Memorandum or such amendment or supplement in reliance
upon and in conformity with written information relating to the Initial
Purchasers furnished to the Issuers by the Initial Purchasers expressly for use
therein, and will reimburse the Issuers and such controlling persons for any
legal or other expenses reasonably incurred by any of the Issuers and such
controlling or affiliated persons in connection with investigating, preparing to
defend, defending or appearing as a third-party witness in connection with any
such action or claim.

          The indemnity agreement in this Section 8(b) shall be in addition to
any liability which the Initial Purchasers may otherwise have.

          (c) Promptly after receipt by an indemnified party under Section 8(a)
or 8(b) of notice of the commencement of any action (including any governmental
investigation), such indemnified party shall, if a claim in respect thereof is
to be made against the indemnifying party under such subsection, notify the
indemnifying party in writing of the commencement thereof; but the omission so
to notify the indemnifying party shall not relieve it from any liability which
it may have to any

                                       28
<PAGE>
 
indemnified party under Section 8(a) or 8(b), except to the extent it was
unaware of such action and has been prejudiced in any material respect by such
failure, or from any liability which it may have to any indemnified party
otherwise than under such Section 8(a) or 8(b).  In case any such action shall
be brought against any indemnified party and it shall notify the indemnifying
party of the commencement thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it shall wish, jointly with any
other indemnifying party similarly notified, to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified party, and after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party shall not be liable to such
indemnified party under such subsection for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation.  If, however, (i) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party or (ii) an indemnified party
shall have reasonably concluded that representation of such indemnified party
and the indemnifying party by the same counsel would be inappropriate under
applicable standards of professional conduct due to actual or potential
differing interests between them and the indemnified party so notifies the
indemnifying party, then the indemnified party shall be entitled to employ
counsel different from counsel for the indemnifying party at the expense of the
indemnifying party and the indemnifying party shall not have the right to assume
the defense of such indemnified party.  In no event shall the indemnifying
parties be liable for fees and expenses of more than one counsel (in addition to
local counsel) for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same set of allegations or circumstances.  The counsel with respect to which
fees and expenses shall be so reimbursed shall be designated in writing by the
Initial Purchasers in the case of parties indemnified pursuant to Section 8(a)
and by Radnor Holdings Corporation in the case of parties indemnified pursuant
to Section 8(b).

          The Issuers shall not be liable for any settlement of any such action
or proceeding effected without the Company's written consent (not to be
unreasonably withheld) and if settled with its written consent or if there is a
final judgment for the plaintiff, the Issuers agree to indemnify and hold
harmless each Initial Purchaser, its officers, authorized representatives and
directors and each person, if any, who controls the Initial Purchasers within
the meaning of Section 15 of the Securities Act and Section 20 of the Exchange
Act to the extent provided in this Agreement.  Without limiting the generality
of the foregoing, no indemnifying party shall, without the prior written consent
of the indemnified party, effect any settlement of any pending or threatened
proceeding in respect of which any indemnified party is or has been threatened
to be made a party by such indemnified

                                       29
<PAGE>
 
party and to which the indemnity herein is applicable; provided, however, that
                                                       --------  -------      
an indemnifying party may effect such a settlement without the consent of the
indemnified party if such settlement includes an unconditional release of such
indemnified party from all liability for claims that are the subject matter of
such proceeding or the indemnifying party indemnifies the indemnified party in
writing and posts a bond for an amount equal to the maximum liability for all
such claims as contemplated above.

          (d) If the indemnification provided for in paragraphs (a) and (b) of
this Section 8 is for any reason unavailable to (other than by reason of
exceptions provided therein), or insufficient to hold harmless, an indemnified
party in respect of any losses, claims, damages or liabilities (or actions in
respect thereof) referred to therein, then each indemnifying party under such
paragraphs, in lieu of indemnifying such indemnified party thereunder and in
order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect
(i) the relative benefits received by the indemnifying party or parties on the
one hand and the indemnified party or parties on the other hand from the
offering of the Securities or (ii) if the allocation provided by the foregoing
clause (i) is not permitted by applicable law, not only such relative benefits
but also the relative fault of the indemnifying party or parties on the one hand
and the indemnified party or parties on the other hand in connection with the
statements or omissions or alleged statements or omissions that resulted in such
losses, claims, damages or liabilities (or actions in respect thereof) as well
as any other relevant equitable considerations.  The relative benefits received
by the Issuers on the one hand and the Initial Purchasers on the other hand
shall be deemed to be in the same proportion as the total proceeds from the
offering of the Securities (net of discounts and commissions but before
deducting expenses) received by the Issuers bears to the total discounts and
commissions received by the Initial Purchasers, as set forth on the cover page
of the Final Offering Memorandum.  The relative fault of the parties shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Issuers, on the one hand
or in writing by the Initial Purchasers, on the other hand, the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission, and any other equitable considerations
appropriate in the circumstances.

          (e) The parties agree that it would not be just and equitable if
contribution pursuant to this Section 8 were determined by pro rata allocation
                                                           --- ----           
(even if the Issuer and the Initial Purchasers were treated as one entity for
such purpose) or by any other method of allocation that does not take account of
the equitable considerations referred to in the immediately

                                       30
<PAGE>
 
preceding paragraph.  The amount paid or payable by an indemnified party as a
result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to in Section 8(d) shall be deemed to include, subject to the
limitations set forth above, any legal fees or other expenses reasonably
incurred by such indemnified party in connection with defending or investigating
any such action or claim.  Notwithstanding the provisions of this Section 8, in
no event shall the Initial Purchasers be required to contribute any amount in
excess of the Initial Purchasers' discounts and commissions applicable to the
Notes.  No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
Person who was not guilty of such fraudulent misrepresentation.  The amount paid
or payable by any party as a result of this Section 8(e) shall be deemed to
include any legal or other expenses reasonably incurred by such party in
connection with investigating, preparing to defend or defending such claim.

          (f) Promptly after receipt by any party to this Agreement of notice of
the commencement of any action, suit or proceeding, such party will, if a claim
for contribution in respect thereof is to be made against another party (the
"contributing party"), notify the contributing party of the commencement
 ------------------                                                     
thereof; but the omission so to notify the contributing party will not relieve
it from any liability which it may have to any other party for contribution
under the Securities Act, the Exchange Act or otherwise, except to the extent it
was unaware of such action and has been prejudiced in any material respect by
such failure or from any liability which it may have to any other party other
than for contribution under the Securities Act, the Exchange Act or otherwise.
In case any such action, suit or proceeding is brought against any party, and
such party notifies a contributing party of the commencement thereof, the
contributing party will be entitled to participate therein with the notifying
party and any other contributing party similarly notified.

          9.   Survival of Representations and Warranties.  The respective
               ------------------------------------------                 
indemnities, agreements, representations, warranties and other statements of the
Issuers and the Initial Purchasers, as set forth in this Agreement or made by or
on behalf of them, respectively, pursuant to this Agreement, shall remain in
full force and effect, regardless of any investigation (or any statement as to
the results thereof) made by or on behalf of the Initial Purchasers or any
controlling person of the Initial Purchasers, any of the Issuers, or an officer
or director or controlling person of any of the Issuers, and shall survive
delivery of and payment for the Securities.

          10.  Termination.  The obligations of the Initial Purchasers hereunder
               -----------                                                      
may be terminated by the Initial Purchasers by notice given to and received by
the Company prior to delivery of and payment for the Securities, if, prior to
that time, any of

                                       31
<PAGE>
 
the events described in Section 7(d), 7(k) or 7(l) shall have occurred or if the
Initial Purchasers shall decline to purchase the Securities for any reason
permitted under this Agreement.

          11.  Default by Initial Purchasers.  (a)  If any Initial Purchaser
               -----------------------------                                
shall default in its obligation to purchase the Securities which it has agreed
to purchase hereunder, the non-defaulting Initial Purchaser may in its
discretion arrange for it or another party or other parties to purchase such
Securities on the terms contained herein.  If within 24 hours after such default
by any Initial Purchaser the non-defaulting Initial Purchaser does not arrange
for the purchase of such Securities, then the Issuers shall be entitled to a
further period of 24 hours within which to procure another party or other
parties satisfactory to the non-defaulting Initial Purchaser to purchase such
Securities on such terms.  In the event that, within the respective prescribed
periods, the non-defaulting Initial Purchaser notifies the Issuers that it has
so arranged for the purchase of such Securities, or the Issuers notify the non-
defaulting Initial Purchaser that they have so arranged for the purchase of such
Securities, the non-defaulting Initial Purchaser or the Issuers shall have the
right to postpone the Closing Date for a period of not more than seven days, in
order to effect whatever changes may thereby be made necessary in the Final
Offering Memorandum or in any other documents or arrangements, and the Issuers
agree to prepare promptly any amendments or supplements to the Final Offering
Memorandum which in the opinion of the non-defaulting Initial Purchaser may
thereby be made necessary.  The term "Initial Purchasers" as used in this
Agreement shall include any person substituted under this Section with like
effect as if such person had originally been a party to this Agreement with
respect to such Securities.

          (b)  If, after giving effect to any arrangements for the purchase of
the Securities of a defaulting Initial Purchaser by the non-defaulting Initial
Purchaser or the Issuers as provided in subsection (a) above, the aggregate
principal amount of such Securities which remain unpurchased exceeds one-
eleventh of the aggregate principal amount of all the Securities, then this
Agreement shall thereupon terminate without liability on the part of any non-
defaulting Initial Purchaser or the Issuers, except for the expenses to be borne
by the Issuers as provided in Section 7 and the indemnity agreement in Section
8, but nothing herein shall relieve a defaulting Initial Purchaser from
liability for its default.

          12.  Default by the Issuers.  If (a) the Issuers shall fail to tender
               ----------------------                                          
the Securities for delivery to the Initial Purchasers for any reason or (b) the
Initial Purchasers shall decline to purchase the Securities for any reason
permitted under this Agreement (including the termination of this Agreement
pursuant to Section 10), the Issuers shall jointly and severally reimburse the
Initial Purchasers for the reasonable fees and expenses of its counsel and for
such other reasonable out-of-

                                       32
<PAGE>
 
pocket expenses as shall have been incurred by it in connection with this
Agreement and the proposed purchase of the Securities, and upon demand the
Issuers shall jointly and severally pay the full amount of such fees and
expenses to the Initial Purchasers.

          13.  Notices.  All statements, requests, notices and agreements
               -------                                                   
hereunder shall be in writing or by written telecommunication, and shall be
sufficient in all respects if delivered or sent by registered mail, if to the
Initial Purchasers, to Alex. Brown & Sons Incorporated at 1290 Avenue of the
Americas, 10th Floor, New York, New York 10104, Attention:  High Yield
Department; and if to any of the Issuers, to Radnor Holdings Corporation, 3
Radnor Corporate Center, Suite 300, 100 Matsonford Road, Radnor, PA 19087,
Attention:  Treasurer.

          14.  Parties.  This Agreement shall be binding upon, and inure solely
               -------                                                         
to the benefit of, the Initial Purchasers, the Issuers, and, to the extent
provided in Section 8 hereof, the officers and directors of the Issuers and each
person who controls the Issuers or the Initial Purchasers and their respective
heirs, executors, administrators, successors and assigns, and no other person
shall acquire or have any right under or by virtue of this Agreement.  No
purchaser of any of the Securities from the Initial Purchasers shall be deemed a
successor or assign by reason merely of such purchase.

          15.  Headings.  The headings of the sections of this Agreement have

of this Agreement.

          16.  Time of Essence.  Time shall be of the essence of this Agreement.

Dear Ladies and Gentlemen:

          In connection with our proposed purchase of $________ aggregate
principal amount of 10% Senior Notes due 2003 (the "Notes") of Radnor Holdings
                                                    -----                     
Corp., a Delaware corporation (the "Company"), we confirm that:
                                    -------                    

          1.  We understand that the Senior Notes and the Guarantees thereon
     (together, the "Securities") have not been registered under the Securities
                     ----------                                                
     Act of 1933, as amended (the "Securities Act") or under the securities laws
                                   --------------                               
     of any state and, unless so registered, may not be sold except as permitted
     in the following sentence.  We agree on our own behalf and on behalf of any
     investor account for which we are purchasing Securities to offer, sell or
     otherwise transfer such Securities prior to the date which is three years
     after the later of the date of original issue and the last date on which
     the Company or any affiliate of the Company was the owner of such
     Securities (or any predecessor thereto) (the "Resale Restriction
                                                   ------------------
     Termination Date") only (a) to the Company, (b) pursuant to a registration
     ----------------                                                          
     statement which has been declared effective under the Securities Act, (c)
     so long as the Securities are eligible for resale pursuant to Rule 144A
     under the Securities Act, to a person we reasonably believe is a qualified
     institutional buyer under Rule 144A (a "QIB") that purchases for its own
                                             ---                             
     account or for the account of a QIB and to whom notice is given that the
     transfer is being made in reliance on Rule 144A, (d) pursuant to offers and
     sales to non-U.S. persons that occur outside the United States within the
     meaning of Regulation S under the Securities Act, (e) to an institutional
     "accredited investor" within the meaning of subparagraph (a)(1), (2), (3)
     or (7) of Rule 501 under the Securities Act that is purchasing for his own
     account or for the account of

                                      A-1
<PAGE>
 
     such an institutional "accredited investor," in each case in a minimum
     principal amount of Senior Notes of $250,000, for investment purposes and
     not with a view to, or for offer or sale in connection with, any
     distribution thereof in violation of the Securities Act or (f) pursuant to
     any other available exemption from the registration requirements of the
     Securities Act, subject in each of the foregoing cases to any requirement
     of law that the disposition of our property or the property of such
     investor account or accounts be at all times within our or their control
     and to compliance with any applicable state securities laws.  The foregoing
     restrictions on resale will not apply subsequent to the Resale Restriction
     Termination Date.  If any resale or other transfer of the Securities is
     proposed to be made pursuant to clause (e) above prior to the Resale
     Restriction Termination Date, the transferor shall deliver a letter from
     the transferee substantially in the form of this letter to the Trustee,
     which shall provide, among other things, that the transferee is an
     institutional "accredited investor" within the meaning of subparagraph
     (a)(1), (2), (3) or (7) of Rule 501 under the Securities Act and that it is
     acquiring such Securities for investment purposes and not for distribution
     in violation of the Securities Act.  We acknowledge on our own behalf and
     on behalf of any investor account for which we are purchasing Securities
     that the Company and the Trustee reserve the right prior to any offer, sale
     or other transfer prior to the Resale Restriction Termination Date of the
     Securities pursuant to clauses (d), (e) or (f) above to require the
     delivery of an opinion of counsel, certifications and/or other information
     satisfactory to the Company and the Trustee.

          2.  We are an institutional "accredited investor" (as defined in Rule
     501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act)
     purchasing for our own account or for the account of such an institutional
     "accredited investor," and we are acquiring the Securities for investment
     purposes and not with a view to, or for offer or sale in connection with,
     any distribution in violation of the Securities Act and we have such
     knowledge and experience in financial and business matters as to be capable
     of evaluating the merits and risks of our investment in the Securities, and
     we and any accounts for which we are acting are each able to bear the
     economic risk of our or its investments.

          3.  We are acquiring at least $250,000 principal amount of the Senior
     Notes and we are acquiring the Securities purchased by us for our own
     account or for one or more accounts as to each of which we exercise sole
     investment discretion.

existing as a corporation or a limited partnership in good standing under the

<PAGE>
 
          (d) The Indenture has been duly authorized, executed and delivered by
the Company and each of the Delaware Subsidiaries and, assuming due
authorization, execution and delivery by the other parties thereto, is a legal,
valid and binding agreement of the Company and the Guarantors enforceable
against the Company and each of the Guarantors in accordance with its terms,
except as may be limited by bankruptcy, insolvency, reorganization, moratorium,
fraudulent conveyance or fraudulent transfer or other similar laws relating to
or affecting the enforcement of creditors' rights generally and except as the
enforceability of the Indenture is subject to the application of general
principles of equity (regardless of whether considered in a proceeding in at law
or in equity) including, without limitation, (i) the possible unavailability of
specific performance, injunctive relief or any other equitable remedy and (ii)
concepts of materiality, reasonableness, good faith and fair dealing.  The
Indenture conforms in all material respects to the description thereof set forth
in the Final Offering Memorandum.

          (e) The Notes have been duly and validly authorized and, when executed
and authenticated in accordance with the terms of the Indenture and delivered to
and paid for by the Initial Purchasers in accordance with the terms of the
Purchase Agreement, (i) will be legal, valid and binding obligations of the
Company enforceable against the Company in accordance with their terms, except
as may be limited by bankruptcy, insolvency, reorganization, moratorium,
fraudulent conveyance or fraudulent transfer or other similar laws relating to
or affecting the enforcement of creditors' rights generally and except as the
enforceability of the Notes is subject to the application of general principles
of equity (regardless of whether considered in a proceeding at law or in equity)
including, without limitation, (A) the possible unavailability of specific
performance, injunctive relief or any other equitable remedy and (B) concepts of
materiality, reasonableness, good faith and fair dealing and (ii) will be
entitled to the benefits of the Indenture.  The Securities conform in all
material respects to the description thereof set forth in the Final Offering
Memorandum under the heading "Description of the Notes."

          (f) The Guarantees have been duly and validly authorized by the
Delaware Subsidiaries and, when the Notes have been executed by the Company and
authenticated, and the Guarantees have been executed by the Guarantors, in
accordance with the terms of the Indenture and the Guarantees have been
delivered to the Initial Purchasers in accordance with the terms of the Purchase
Agreement, the Guarantees (i) will be legal, valid and binding obligations of
the Guarantors enforceable against the Guarantors in accordance with their
terms, except as may be limited by bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance or fraudulent transfer or other similar laws
relating to or affecting the enforcement of creditors' rights generally and
except as the enforceability of the Guarantees is subject to the application of
general

                                      B-2
<PAGE>
 
principles of general equity (regardless of whether considered in a proceeding
at law or in equity) including, without limitation, (i) the possible
unavailability of specific performance, injunctive relief or any other equitable
remedy and (ii) concepts of materiality, reasonableness, good faith and fair
dealing and (ii) will be entitled to the benefits of the Indenture.  Such
counsel may assume, in rendering the opinion expressed in this paragraph (f),
that, at the time of the execution and delivery by each of the Guarantors of the
Guarantees, each Guarantor is, and after giving effect to any payment by such
Guarantor under the Guarantee (or any other provision of the Indenture under
which such Guarantor agrees to be liable for the payment of principal of,
premium, if any, and interest on the Notes) such Guarantor will be, Solvent and
that adequate consideration exists, in the case of each Guarantor, for its
execution, delivery and performance of the Guarantee (and its agreements in
respect of any such other provision).

          (g) The Registration Rights Agreement has been duly authorized,
executed and delivered by the Company and each of the Delaware Subsidiaries and,
assuming due authorization, execution and delivery by the other parties thereto,
is a legal, valid and binding agreement of the Company and the Guarantors
enforceable against the Company and the Guarantors in accordance with its terms,
except (i) as may be limited by bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance or fraudulent transfer or other similar laws
relating to or affecting the enforcement of creditors' rights generally and
except as the enforceability of the Registration Rights Agreement is subject to
the application of general principles of equity (regardless of whether
considered in a proceeding at law or in equity) including, without limitation,
(A) the possible unavailability of specific performance, injunctive relief or
any other equitable remedy and (B) concepts of materiality, reasonableness, good
faith and fair dealing, and (ii) for limitations on the enforceability of
indemnification provisions imposed by law or public policy.  The Registration
Rights Agreement conforms in all material respects to the description thereof
set forth in the Final Offering Memorandum.

          (h)  The execution, delivery and performance by the Company and each
of the Guarantors of the Purchase Agreement, the Indenture, the Securities and
the Registration Rights Agreement, in each case to the extent the Company and
each of the Guarantors is a party, and the performance by the Company and each
of the Guarantors of its obligations thereunder, including, without limitation,
the issuance, sale and delivery of the Securities, the performance by the
Company and each of the Guarantors of its obligations on or prior to the Closing
Date with respect to the Acquisitions and the Other Financings, and the
execution, delivery and performance by the Company or any Guarantor of the Other
Transaction Documents, do not and will not (1) to our knowledge, result in a
breach or violation of any of the terms or provisions of, or constitute a
default under, any indenture,

                                      B-3

mortgage, deed of trust, bank loan or credit agreement, lease or other agreement
or instrument to which the Company or any Guarantor is a party or by which the
Company or any Guarantor is bound or to which any of the property or assets of
the Company or any Guarantor is subject, (2) result in any violation of the
provisions of the Certificate of Incorporation or Certificate of Limited

Company or any Guarantor of any court or governmental agency or body having
jurisdiction over the Company or any Guarantor or any of its properties (other
than state securities or Blue Sky laws, as to which such counsel need express no
opinion), (4) to our knowledge, result in or require the creation or imposition
of any Lien upon or with respect to any of the properties of the Company or any
Guarantor, except pursuant to the terms of the Indenture or the Credit
Agreements, or (5) to our knowledge, constitute a default under any ordinance,
license or permit, except, in the case of the events specified in clauses (1),
(4) and (5) above, for such breaches, conflicts, violations or defaults which
would not have a Material Adverse Effect.

          (i)  No consent, approval, authorization, order, registration or
qualification of or with any court or governmental agency or body is required
for the issue and sale of the Securities or the performance by the Company and
each of the Guarantors of its obligations under the Purchase Agreement, the
Indenture and the Registration Rights Agreement or the consummation of the
Acquisitions or the Other Financings, including, without limitation, the
issuance, sale and delivery of the Securities and the execution, delivery and
performance by the Company and the Guarantors of the Other Transaction
Documents, except such consents, approvals, authorizations, registrations or
qualifications as have been obtained or as may be required under state
securities or Blue Sky laws in connection with the offer and sale of the
Securities, and as may be required by the Securities Act, the securities or Blue
Sky laws of the various states and the Trust Indenture Act in conjunction with
an exchange offer for, or registered resale of, the Securities pursuant to the
Registration Rights Agreement; and the Company and each Delaware Subsidiary has
corporate or partnership power and authority to enter into and perform its
obligations under the Purchase Agreement, the Indenture, the Registration Rights
Agreement and the Other Transaction Documents and to issue, sell and deliver the
Securities to be sold by the Issuers to the Initial Purchasers as provided in
the Purchase Agreement.

          (j)  The Stock Purchase Agreement, the Non-Competition Agreement, the
Consulting Agreement and Partnership Interest Purchase Agreement, Sales Agent
Extension and Modification

                                      B-4
<PAGE>
 
Agreement, License Extension and Modification Agreement, the Equipment Use
Extension and Modification Agreement, assuming due authorization, execution and
delivery by Richard Davidovich, James River Paper Company and the other parties
thereto, as the case may be, are legal, valid and binding agreements of the
Company and each Guarantor that is a party thereto, enforceable against each of
them in accordance with their terms, except as may be limited by bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance or fraudulent
transfer or other similar laws relating to or affecting the enforcement of
creditors' rights generally and except as the enforceability of such agreements
is subject to the application of general principles of equity (regardless of
whether in a proceeding at law or in equity) including, without limitation, (i)
the possible unavailability of specific performance, injunctive relief or any
other equitable remedy and (ii) concepts of materiality, reasonableness, good
faith and fair dealing.

          (k)  Such counsel has no knowledge of any legal or governmental
proceedings pending or threatened to which the Company or any Guarantor is a
party or of which any property of the Company or any Guarantor is the subject
that could reasonably be expected to have, individually or in the aggregate, a
Material Adverse Effect.

          (l) Such counsel has no knowledge that any of the Company or any
Delaware Subsidiary is in violation of any term or provision of its Certificate
of Incorporation or Certificate of Limited Partnership or By-Laws or Agreement
of Limited Partnership, as the case may be, in each case as amended to the date
hereof.

          (m) Such counsel has no knowledge of any legal or governmental
proceedings, Material Licenses, contracts or documents of a character required
by the representations of the Company or the Delaware Subsidiaries in the
Purchase Agreement to be described in the Final Offering Memorandum which are
not described as required.

          (n) Neither the Company nor any of the Guarantors is an "investment
company" or an entity "controlled" by an "investment company," as such terms are
defined in the Investment Company Act and the rules and regulations of the
Commission promulgated thereunder.

          (o) Assuming that the representations and warranties of the Initial
Purchasers set forth in the Purchase Agreement are true and correct, the
representations and warranties of the Issuers set forth in Section 1(aa) through
1(ag) of the Purchase Agreement are true and correct and, with respect to any
institutional "accredited investors," the representations and warranties
contained in the Transferee Letter of Representations set forth in Exhibit A to
the Purchase Agreement are true and correct, it is not necessary in connection
with the offer, sale

                                      B-5
<PAGE>
 
and delivery of the Securities to the Initial Purchasers or in connection with
the initial resale of the Securities, in each case in the manner contemplated by
the Purchase Agreement and the Final Offering Memorandum, to register the
Securities under the Securities Act or to qualify the Indenture under the Trust
Indenture Act.  The Indenture is in sufficient form in all material respects for
qualification under the Trust Indenture Act and the rules and regulations of the
Commission promulgated thereunder.

          (p) When the Securities are issued and delivered pursuant to the
Purchase Agreement, the Securities will not be of the same class (within the
meaning of Rule 144A under the Securities Act) as securities of the Issuers, if
any, which are listed on a national securities exchange registered under Section
6 of the Exchange Act and the rules and regulations of the Commission
promulgated thereunder or quoted in a U.S. automated interdealer quotation
system.  Accordingly, the offer and sale of the Securities in the manner
contemplated by the Purchase Agreement and the Final Offering Memorandum will be
in compliance with paragraph (d)(3) of Rule 144A under the Securities Act.

          (q) The Final Offering Memorandum appears on its face to comply as to
form in all material respects with the applicable requirements of paragraph
(d)(4) of Rule 144A under the Securities Act (except that such counsel need
express no opinion or belief as to the financial statements or other financial
data included in or omitted from the Final Offering Memorandum).

          (r)  The statements set forth in the Final Offering Memorandum under
the caption "Certain Federal Income Tax Considerations" are accurate and
complete in all material respects and fairly present the information set forth
therein.

          In addition, such counsel shall state that they have participated in
conferences with officers and representatives of the Issuers, representatives of
Arthur Andersen LLP and Deloitte & Touche LLP, independent auditors for the
Company and StyroChem, respectively, and representatives of the Initial
Purchasers and their counsel at which conferences the contents of the Final
Offering Memorandum were discussed.  Although such counsel has not investigated
or verified independently, and does not pass upon or assume any responsibility
for, the accuracy, completeness or fairness of the statements contained in the
Final Offering Memorandum, such counsel shall state that, based upon the
foregoing, they have no knowledge that the Final Offering Memorandum, as of its
date and as of the Closing Date, contained or contains an untrue statement of a
material fact or omitted or omits to state a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.  Such counsel need express no view as to the
financial statements and other financial data included in or omitted from the
Final Offering Memorandum.

                                      B-6
<PAGE>
 
          Such counsel need express no opinion as to the laws of any
jurisdiction other than the laws of the State of New York, the General
Corporation Law of the State of Delaware, the Delaware Revised Uniform Limited
Partnership Act and the federal laws of the United States.  In addition to
relying on Texas and Quebec counsel as contemplated by Section 7(h) of the
Purchase Agreement, such counsel may also rely on the opinion delivered by
counsel to the Sellers pursuant to the Stock Purchase Agreement with respect to
the opinions in paragraphs (b)(iii), (b)(v), (j) and (k) hereof.

          Such counsel may also state that, when reference is made in such
opinion to such counsel's "knowledge", such reference means the actual knowledge
attributable to such counsel's representation of the Company of only those
attorneys who have given substantive attention to the transactions contemplated
by the Purchase Agreement and the Other Transaction Documents.

          Such counsel may also state that, in rendering the opinions set forth
in paragraphs (d), (e), (f), (g) and (j) above, such counsel expresses no
opinion with respect to (i) any provision of any of the Indenture, the
Registration Rights Agreement and the Stock Purchase Agreement insofar as it
provides for the payment or reimbursement of costs and expenses or
indemnification for claims, losses, or liabilities in excess of a reasonable
amount determined by a court or other tribunal, (ii) the ability of any party to
collect attorneys' fees and costs in an action involving any of the Indenture,
the Registration Rights Agreement and the Stock Purchase Agreement if such party
is not the prevailing party in such action or to the extent such fees and costs
are greater than such fees and costs as may be determined to be reasonable by a
court or other tribunal or (iii) any provisions of the Indenture, the
Registration Rights Agreement and the Stock Purchase Agreement providing for
liquidated damages, if the amount of such damage is found to be in the nature of
a penalty.

Ladies and Gentlemen:
 
  Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned tenders to the Issuer the principal amount of Old Notes indicated
above. Subject to, and effective upon, the acceptance for exchange of the Old
Notes tendered with this Letter, the undersigned exchanges, assigns and
transfers to, or upon the order of, the Issuer all right, title and interest
in and to the Old Notes tendered.
 
  The undersigned constitutes and appoints the Exchange Agent as his or her
agent and attorney-in-fact (with full knowledge that the Exchange Agent also
acts as the agent of the Issuer) with respect to the tendered Old Notes, with
full power of substitution, to: (a) deliver certificates for such Old Notes;
(b) deliver Old Notes and all accompanying evidence of transfer and
authenticity to or upon the order of the Issuer upon receipt by the Exchange
Agent, as the undersigned's agent, of the New Notes to which the undersigned
is entitled upon the acceptance by the Issuer of the Old Notes tendered under
the Exchange Offer; and (c) receive all benefits and otherwise exercise all
rights of beneficial ownership of the Old Notes, all in accordance with the
terms of the Exchange Offer. The power of attorney granted in this paragraph
shall be deemed irrevocable and coupled with an interest.
 
  The undersigned hereby represents and warrants that he or she has full power
and authority to tender, exchange, assign and transfer the Old Notes tendered
hereby and that the Issuer will acquire good and unencumbered title thereto,
free and clear of all liens, restrictions, charges and encumbrances and not
subject to any adverse claim. The undersigned will, upon request, execute and
deliver any additional documents deemed by the Issuer to be necessary or
desirable to complete the assignment and transfer of the Old Notes tendered.
 
  The undersigned agrees that acceptance of any tendered Old Notes by the
Issuer and the issuance of New Notes (together with the New Guarantees of the
Guarantors (as defined in the Prospectus) with respect thereto) in exchange
therefor shall constitute performance in full by the Issuer and the Guarantors
of their obligations under the Registration Rights Agreement (as defined in
the Prospectus) and that, upon the issuance of the New Notes, the Issuer and
the Guarantors will have no further obligations or liabilities thereunder
(except in certain limited circumstances). By tendering Old Notes, the
undersigned certifies (a) that it is not an affiliate of the Issuer, that it
is not a broker-dealer that owns Old Notes acquired directly from the Issuer
or an affiliate of the Issuer, that it is acquiring the New Notes offered
hereby in the ordinary course of the undersigned's business and that the
undersigned has no arrangement or understanding with any person to participate
in the distribution of such New Notes; (b) that it is an affiliate of the
Issuer or of the initial purchaser of the Old Notes in the Offering and that
it will comply with the registration and prospectus delivery requirements of
the Securities Act to the extent applicable to it; or (c) that it is a
Participating Broker-dealer (as defined in the Registration Rights Agreement)
and that it will deliver a prospectus in connection with any resale of the New
Notes.
 
  The undersigned acknowledges that, if it is a broker-dealer that will
receive New Notes for its own account, it will deliver a prospectus in
connection with any resale of such New Notes. By so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act.
 
  The undersigned understands that the Issuer may accept the undersigned's
tender by delivering written notice of acceptance to the Exchange Agent, at
which time the undersigned's right to withdraw such tender will terminate.
 
  All authority conferred or agreed to be conferred by this Letter shall
survive the death or incapacity of the undersigned, and every obligation of
the undersigned under this Letter shall be binding upon the undersigned's
heirs, personal representatives, successors and assigns. Tenders may be
withdrawn only in accordance with the procedures set forth in the Instructions
contained in this Letter.
 
  Unless otherwise indicated under "Special Delivery Instructions" below, the
Exchange Agent will deliver New Notes (and, if applicable, a certificate for
any Old Notes not tendered but represented by a certificate also encompassing
Old Notes which are tendered) to the undersigned at the address set forth in
Box 1.

         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER
 
  1. DELIVERY OF THIS LETTER AND CERTIFICATES. Certificates for Old Notes or a
Book-Entry Confirmation, as the case may be, as well as a properly completed
and duly executed copy of this Letter and any other documents required by this
Letter, must be received by the Exchange Agent at its address set forth herein
on or before the Expiration Date. The method of delivery of this Letter,
certificates for Old Notes or a Book-Entry Confirmation, as the case may be,
and any other required documents is at the election and risk of the tendering
holder, but except as otherwise provided below, the delivery will be deemed
made when actually received by the Exchange Agent. If delivery is by mail, the
use of registered mail with return receipt requested, properly insured, is
suggested.
 
  If tendered Old Notes are registered in the name of the signer of the Letter
of Transmittal and the New Notes to be issued in exchange therefore are to be
issued (and any untendered Old Notes are to be reissued) in the name of the
registered holder, the signature of such signer need not be guaranteed. In any
other case, the tendered Old Notes must be endorsed or accompanied by written
instruments of transfer in form satisfactory to the Issuer and duly executed by
the registered holder and the signature on the endorsement or instrument of
transfer must be guaranteed by a bank, broker, dealer, credit union, savings
association, clearing agency or other institution (each an "Eligible
Institution") that is a member of a recognized signature guarantee medallion
program within the meaning of Rule 17Ad-15 under the Exchange Act. If the New
Notes and/or Old Notes not exchanged are to be delivered to an address other
than that of the registered holder appearing on the note register for the Old
Notes, the signature on the Letter of Transmittal must be guaranteed by an
Eligible Institution.
 
  Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to
tender Old Notes should contact such holder promptly and instruct such holder
to tender Old Notes on such beneficial owner's behalf. If such beneficial owner
wishes to tender such Old Notes himself, such beneficial owner must, prior to
completing and executing the Letter of Transmittal and delivering such Old
Notes, either make appropriate arrangements to register ownership of the Old
Notes in such beneficial owner's name or follow the procedures described in the
immediately preceding paragraph. The transfer of record ownership may take
considerable time.
 
  Holders whose Old Notes are not immediately available or who cannot deliver
their Old Notes or a Book-Entry Confirmation, as the case may be, and all other
required documents to the Exchange Agent on or before the Expiration Date may
tender their Old Notes pursuant to the guaranteed delivery procedures set forth
in the Prospectus. Pursuant to such procedure: (i) tender must be made by or
through an Eligible Institution; (ii) prior to the Expiration Date, the
Exchange Agent must have received from the Eligible Institution a properly
completed and duly executed Notice of Guaranteed Delivery (by telegram, telex,
facsimile transmission, mail or hand delivery) (x) setting forth the name and
address of the holder, the description of the Old Notes and the principal
amount of Old Notes tendered, (y) stating that the tender is being made thereby
and (z) guaranteeing that, within five New York Stock Exchange trading days
after the date of execution of such Notice of Guaranteed Delivery, this Letter
together with the certificates representing the Old Notes or a Book-Entry
Confirmation, as the case may be, and any other documents required by this
Letter will be deposited by the Eligible Institution with the Exchange Agent;
and (iii) the certificates for all tendered Old Notes or a Book-Entry
Confirmation, as the case may be, as well as all other documents required by
this Letter, must be received by the Exchange Agent within five New York Stock
Exchange trading days after the date of execution of such Notice of Guaranteed
Delivery, all as provided in the Prospectus under the caption "The Exchange
Offer--Procedures for Tendering Old Notes."
 
  The method of delivery of Old Notes and all other documents is at the
election and risk of the holder. If sent by mail, it is recommended that
registered mail, return receipt requested, be used, proper insurance be
obtained, and the mailing be made sufficiently in advance of the Expiration
Date to permit delivery to the Exchange Agent on or before the Expiration Date.
 
 
                                       8
<PAGE>
 
  Unless an exemption applies under the applicable law and regulations
concerning "backup withholding" of federal income tax, the Exchange Agent will
be required to withhold, and will withhold, 31% of the gross proceeds otherwise
payable to a holder pursuant to the Exchange Offer if the holder does not
provide his or her taxpayer identification number (social security number or
employer identification number) and certify that such number is correct. Each
tendering holder should complete and sign the main signature form and the
Substitute Form W-9 included as part of the Letter of Transmittal, so as to
provide the information and certification necessary to avoid backup
withholding, unless an applicable exemption exists and is proved in a manner
satisfactory to the Issuer and the Exchange Agent.
 
  If a holder desires to accept the Exchange Offer and time will not permit a
Letter of Transmittal or Old Notes to reach the Exchange Agent before the
Expiration Date, a tender may be effected if the Exchange Agent has received at
its office listed on the back cover hereof on or prior to the Expiration Date a
letter, telegram or facsimile transmission from an Eligible Institution setting
forth the name and address of the tendering holder, the principal amount of the
Old Notes being tendered, the names in which the Old Notes are registered and,
if possible, the certificate numbers of the Old Notes to be tendered, and
stating that the tender is being made thereby and guaranteeing that within
three New York Stock Exchange trading days after the date of execution of such
letter, telegram or facsimile transmission by the Eligible Institution, the Old
Notes, in proper form for transfer, will be delivered by such Eligible
Institution together with a properly completed and duly executed Letter of
Transmittal (and any other required documents). Unless Old Notes being tendered
by the above-described method (or a timely Book-Entry Confirmation) are
deposited with the Exchange Agent within the time period set forth above
(accompanied or preceded by a properly completed Letter of Transmittal and any
other required documents), the Issuer may, at its option, reject the tender.
Copies of a Notice of Guaranteed Delivery which may be used by Eligible
Institutions for the Purposes described in this paragraph are available from
the Exchange Agent.
 
  A tender will be deemed to have been received as of the date when the
tendering holder's properly completed and duly signed Letter of Transmittal
accompanied by the Old Notes (or a timely Book-Entry Confirmation) is received
by the Exchange Agent. Issuances of New Notes in exchange for Old Notes
tendered pursuant to a Notice of Guaranteed Delivery or letter, telegram or
facsimile transmission to similar effect (as provided above) by an Eligible
Institution will be made only against deposit of the Letter of Transmittal (and
any other required documents) and the tendered Old Notes (or a timely Book-
Entry Confirmation).
 
  All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Old Notes will be determined by
the Issuer, whose determination will be final and binding. The Issuer reserves
the absolute right to reject any or all tenders that are not in proper form or
the acceptance of which, in the opinion of the Issuer's counsel, would be
unlawful. The Issuer also reserves the right to waive any irregularities or
conditions of tender as to particular Old Notes. All tendering holders, by
execution of this Letter, waive any right to receive notice of acceptance of
their Old Notes. The Issuer's interpretation of the terms and conditions of the
Exchange Offer (including the Letter of Transmittal and the instructions
thereto) will be final and binding.
 
  Neither the Issuer, the Exchange Agent nor any other person shall be
obligated to give notice of defects or irregularities in any tender, nor shall
any of them incur any liability for failure to give any such notice.
 
  2. PARTIAL TENDERS; WITHDRAWALS. If less than the entire principal amount of
any Old Note evidenced by a submitted certificate or by a Book-Entry
Confirmation is tendered, the tendering holder must fill in the principal
amount tendered in the fourth column of Box 1 above. All of the Old Notes
represented by a certificate or by a Book-Entry Confirmation delivered to the
Exchange Agent will be deemed to have been tendered unless otherwise indicated.
A certificate for Old Notes not tendered will be sent to the holder, unless
otherwise provided in Box 5, as soon as practicable after the Expiration Date,
in the event that less than the entire principal amount of Old Notes
represented by a submitted certificate is tendered (or, in the case of Old
Notes tendered by book-entry transfer, such non-exchanged Old Notes will be
credited to an account maintained by the holder with the Book-Entry Transfer
Facility).
 
 
                                       9
<PAGE>
 
  If not yet accepted, a tender pursuant to the Exchange Offer may be withdrawn
prior to the Expiration Date. To be effective with respect to the tender of Old
Notes, a notice of withdrawal must: (i) be received by the Exchange Agent
before the Issuer notifies the Exchange Agent that it has accepted the tender
of Old Notes pursuant to the Exchange Offer; (ii) specify the name of the
person who tendered the Old Notes; (iii) contain a description of the Old Notes
to be withdrawn, the certificate numbers shown on the particular certificates
evidencing such Old Notes and the principal amount of Old Notes represented by
such certificates; and (iv) be signed by the holder in the same manner as the
original signature on this Letter (including any required signature guarantee).
 
  For a withdrawal to be effective, a written or facsimile transmission notice
of withdrawal must be timely received by the Exchange Agent at its address set
forth on the back cover of the Prospectus prior to the Expiration Date. Any
such notice of withdrawal must specify the person named in the Letter of
Transmittal as having tendered Old Notes to be withdrawn, the certificate
numbers of Old Notes to be withdrawn, the principal amount of Old Notes to be
withdrawn, a statement that such holder is withdrawing his election to have
such Old Notes exchanged, and the name of the registered holder of such Old
Notes, and must be signed by the holder in the same manner as the original
signature on the Letter of Transmittal (including any required signature
guarantees) or be accompanied by evidence satisfactory to the Issuer that the
person withdrawing the tender has succeeded to the beneficial ownership of the
Old Notes being withdrawn. The Exchange Agent will return the properly
withdrawn Old Notes promptly following receipt of notice of withdrawal. All
questions as to the validity of notices of withdrawals, including time of
receipt, will be determined by the Issuer, and such determination will be final
and binding on all parties.
 
  3. SIGNATURES ON THIS LETTER; ASSIGNMENT: GUARANTEE OF SIGNATURES. If this
Letter is signed by the holder(s) of Old Notes tendered hereby, the signature
must correspond with the name(s) as written on the face of the certificate(s)
for such Old Notes, without alteration, enlargement or any change whatsoever.
 
  If any of the Old Notes tendered hereby are owned by two or more joint
owners, all owners must sign this Letter. If any tendered Old Notes are held in
different names on several certificates, it will be necessary to complete, sign
and submit as many separate copies of this Letter as there are names in which
certificates are held.
 
  If this Letter is signed by the holder of record and (i) the entire principal
amount of the holder's Old Notes are tendered; and/or (ii) untendered Old
Notes, if any, are to be issued to the holder of record, then the holder of
record need not endorse any certificates for tendered Old Notes, nor provide a
separate bond power. In any other case, the holder of record must transmit a
separate bond power with this Letter.
 
  If this Letter or any certificate or assignment is signed by trustees,
executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing and proper evidence satisfactory to the
Issuer of their authority to so act must be submitted, unless waived by the
Issuer.
 
  Signatures on this Letter must be guaranteed by an Eligible Institution,
unless Old Notes are tendered: (i) by a holder who has not completed the Box
entitled "Special Delivery Instructions" on this Letter; or (ii) for the
account of an Eligible Institution. In the event that the signatures in this
Letter or a notice of withdrawal, as the case may be, are required to be
guaranteed, such guarantees must be by an eligible guarantor institution which
is a member of The Securities Transfer Agents Medallion Program (STAMP), The
New York Stock Exchanges Medallion Signature Program (MSP) or The Stock
Exchanges Medallion Program (SEMP). If Old Notes are registered in the name of
a person other than the signer of this Letter, the Old Notes surrendered for
exchange must be endorsed by, or be accompanied by a written instrument or
instruments of transfer or exchange, in satisfactory form as determined by the
Issuer, in its sole discretion, duly executed by the registered holder with the
signature thereon guaranteed by an Eligible Institution.
 
  4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. Tendering holders should
indicate, in Box 4 or 5, as applicable, the name and address to which the New
Notes or certificates for Old Notes not exchanged are to be issued or sent, if
different from the name and address of the person signing this Letter. In the
case of issuance in a different name, the tax identification number of the
person named must also be indicated. Holders tendering Old
 
                                       10
<PAGE>
 
Notes by Book-Entry transfer may request that Old Notes not exchanged be
credited to such account maintained at the Book-Entry Transfer Facility as such
holder may designate.
 
  5. TAX IDENTIFICATION NUMBER. Federal income tax law requires that a holder
whose tendered Old Notes are accepted for exchange must provide the Exchange
Agent (as payor) with his or her correct taxpayer identification number
("TIN"), which, in the case of a holder who is an individual, is his or her
social security number. If the Exchange Agent is not provided with the correct
TIN, the holder may be subject to a $50 penalty imposed by the Internal Revenue
Service. In addition, delivery to the holder of the New Notes pursuant to the
Exchange Offer may be subject to back-up withholding. (If withholding results
in overpayment of taxes, a refund may be obtained.) Exempt holders (including,
among others, all corporations and certain foreign individuals) are not subject
to these back-up withholding and reporting requirements. See the enclosed
Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9 for additional instructions.
 
  Under federal income tax laws, payments that may be made by the Issuer on
account of New Notes issued pursuant to the Exchange Offer may be subject to
back-up withholding at a rate of 31%. In order to prevent back-up withholding,
each tendering holder must provide his or her correct TIN by completing the
"Substitute Form W-9" referred to above, certifying that the TIN provided is
correct (or that the holder is awaiting a TIN) and that: (i) the holder has not
been notified by the Internal Revenue Service that he or she is subject to
back-up withholding as a result of failure to report all interest or dividends;
(ii) the Internal Revenue Service has notified the holder that he or she is no
longer subject to back-up withholding; or (iii) in accordance with the
Guidelines, such holder is exempt from back-up withholding. If the Old Notes
are in more than one name or are not in the name of the actual owner, consult
the enclosed Guidelines for information on which TIN to report.
 
  6. TRANSFER TAXES. The Issuer will pay all transfer taxes, if any, applicable
to the transfer of Old Notes to it or its order pursuant to the Exchange Offer.
If, however, the New Notes or certificates for Old Notes not exchanged are to
be delivered to, or are to be issued in the name of, any person other than the
record holder, or if tendered certificates are recorded in the name of any
person other than the person signing this Letter, or if a transfer tax is
imposed by any reason other than the transfer of Old Notes to the Issuer or its
order pursuant to the Exchange Offer, then the amount of such transfer taxes
(whether imposed on the record holder or any other person) will be payable by
the tendering holder. If satisfactory evidence of payment of taxes or exemption
from taxes is not submitted with this Letter, the amount of transfer taxes will
be billed directly to the tendering holder.
 
  Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the certificates listed in this Letter.
 
  7. WAIVER OF CONDITIONS. The Issuer reserves the absolute right to amend or
waive any of the specified conditions in the Exchange Offer in the case of any
Old Notes tendered.
 
  8. MUTILATED, LOST, STOLEN OR DESTROYED CERTIFICATES. Any holder whose
certificates for Old Notes have been mutilated, lost, stolen or destroyed
should contact the Exchange Agent at the address indicated above, for further
instruction.
 
  9. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions relating to the
procedure for tendering, as well as requests for additional copies of the
Prospectus or this Letter, may be directed to the Exchange Agent.
 
  IMPORTANT: THIS LETTER (TOGETHER WITH CERTIFICATES REPRESENTING TENDERED OLD
NOTES OR A BOOK-ENTRY CONFIRMATION AND ALL OTHER REQUIRED DOCUMENTS) MUST BE
RECEIVED BY THE EXCHANGE AGENT ON OR BEFORE THE EXPIRATION DATE (AS DEFINED IN
THE PROSPECTUS).

1933, as amended (the "Old Notes").
 
  The material is being forwarded to you as the beneficial owner of Old Notes
carried by us for your account or benefit but not registered in your name. A
tender of any Old Notes may be made only by us as the registered holder and
pursuant to your instructions. Therefore, the Issuer urges beneficial owners
of Old Notes registered in the name of a broker, dealer, commercial bank,
trust company or other nominee to contact such registered holder promptly if
they wish to tender Old Notes in the Exchange Offer.
 
  Accordingly, we request instructions as to whether you wish us to tender any
or all Old Notes, pursuant to the terms and conditions set forth in the
Prospectus and Letter of Transmittal. We urge you to read carefully the
Prospectus and Letter of Transmittal before instructing us to tender your Old

Date"). Old Notes tendered pursuant to the Exchange Offer may be withdrawn,
subject to the procedures described in the Prospectus, at any time prior to
the Expiration Date.
 
  Your attention is directed to the following:
 
  1. The Exchange Offer is for the exchange of $1,000 principal amount at
maturity of the New Notes for each $1,000 principal amount at maturity of the
Old Notes, of which $100,000,000 aggregate principal amount of the Old Notes
was outstanding as of      , 1997. The terms of the New Notes are
substantially identical (including principal amount, interest rate, maturity,
security and ranking) to the terms of the Old Notes, except that the New Notes
are freely transferrable by holders thereof (except as provided in the
Prospectus).
 
  2. THE EXCHANGE OFFER IS SUBJECT TO CERTAIN CONDITIONS. SEE "THE EXCHANGE
OFFER--CERTAIN CONDITIONS TO THE EXCHANGE OFFER" IN THE PROSPECTUS.

tendering Holder to the Issuer will be paid by the Issuer, except as provided
in the Prospectus and the Letter of Transmittal.
 
  The Exchange Offer is not being made to nor will exchange be accepted from
or on behalf of holders of Old Notes in any jurisdiction in which the making
of the Exchange Offer or the acceptance thereof would not be in compliance
with the laws of such jurisdiction.
 
  If you wish to have us tender any or all of your Old Notes held by us for
your account or benefit, please so instruct us by completing, executing and

The Adjustment Amount (which may be a positive or negative number) will be equal
to the Company's net working capital as of the Closing Date calculated in
accordance with GAAP on a consolidated basis, minus the Company's net working
                                              -----                          
capital as of August 3, 1996 as set forth on Schedule 2.6 to this Agreement,
                                             ------------                   
provided that for purposes of determining the Adjustment Amount the balance
sheet as of the Closing Date will be compared to Schedule 2.6 with respect to
the asset and liability accounts shown on Schedule 2.6.

     2.7  Adjustment Procedure
          --------------------

     (a)  Buyer will cause Arthur Andersen LLP, the Buyer's certified public
accountants, to determine the consolidated net working capital of the Company as
of the close of business on the Closing Date in accordance with GAAP and to
determine the Adjustment Amount based on the consolidated net working capital of
the Company as so determined as of the close of business on the Closing Date as
compared to the consolidated net working capital of the Company as shown on
Schedule 2.6, based on the asset and liability accounts specified on Schedule
2.6 and subject to the instructions provided in Schedule 2.6, but not subject to
any disclosures or statements made in the Disclosure Letter delivered to Sellers
pursuant to this Agreement. Buyer will deliver the statement prepared by Arthur
Andersen LLP showing the calculation of the Adjustment Amount ("Closing
Statement") to Davidovich within sixty (60) days after the Closing Date,
together with copies of Buyer's and Arthur Andersen LLP's work papers, and other
documents and information, used to prepare the Closing Statement. If, within
sixty (60) days following delivery of the Closing Statement and related
documents and information, Davidovich has not given Buyer notice of his
objection to the Closing Statement (such notice must contain a statement of the
basis of Davidovich's objection), then the Company's net working capital
reflected in the Closing Statement will be used in computing the Adjustment
Amount. Buyer agrees upon reasonable notice to make available to Davidovich at
the offices of the Acquired Companies the books and records of the Acquired
Companies as required by Davidovich to verify the determination reflected in the
Closing Statement. If Davidovich gives such notice of objection, 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 Ernst &
Young, certified public accountants (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 workpapers and other documents
and information relating to the disputed issues as the Accountants may request
and

                                       12
<PAGE>
 
are available to that party or its Subsidiaries (or its independent public
accountants), and 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) Buyer and Sellers will each bear 50% of the
fees of the Accountants for such determination.

     (b)  The final determination of the Adjustment Amount shall occur on the
earliest of (i) sixty (60) days after delivery of the Closing Statement to
Davidovich without objection, (ii) written agreement of Davidovich and Buyer to
the Closing Statement or any modification thereof, or (iii) written
determination by the Accountants.  On the tenth (10th) Business Day following
the final determination of the Adjustment Amount, (i) if the Adjustment Amount
is a negative number and greater than negative $1,000,000, the Escrowed Funds
shall be paid to Buyer, and the Sellers shall pay to Buyer (in proportion to the
relative percentage of the Purchase Price payable to each Seller under Section
2.5(b)(iii) (such relative proportions, hereinafter, a "Pro Rata Basis")) an
amount equal to the amount by which the negative Adjustment Amount exceeds
negative $1,000,000, (ii) if the Adjustment Amount is a negative number and less
than or equal to negative $1,000,000, an amount equal to the negative Adjustment
Amount shall be paid to Buyer out of the Escrowed Funds, and the balance of the
Escrowed Funds, if any, shall be paid to the Sellers, and (iii) if the
Adjustment Amount is zero or a positive number, all of the Escrowed Funds shall
be paid to the Sellers, and Buyer shall pay to the Sellers an amount equal to
the positive Adjustment Amount, if any.  All payments of the Escrowed Funds will
be made together with interest at the rate earned thereon.  Payments must be
made in immediately available funds by wire transfer to such bank account as the
party entitled to receive such funds shall specify.  Payments made to Sellers
under this Section and under Section 2.5(b)(iii) shall be paid on a Pro Rata
Basis in accordance with Schedule 2.5(b)(iii), and payments made to Davidovich
on behalf of Sellers other than JR shall be paid to Davidovich and then
distributed by Davidovich to such Sellers in accordance with Schedule
2.5(b)(iii).  Any portion of the Adjustment Amount which is not disputed under
the procedures set forth above shall be paid to the party or parties entitled
thereto in accordance with the provisions of this Section 2.7, and the remaining
portion of the Adjustment Amount shall be paid when any dispute has been
resolved in accordance with the provisions of this Section 2.7.  An example of
the calculation of the amount payable to Sellers at Closing and the calculation
and payment of the Adjustment Amount is set forth on Exhibit 2.7(b) attached
hereto (the assumptions set forth therein being arbitrary and used for
illustrative purposes only).

     2.8  Tax Matters
          -----------

The following provisions shall govern the allocation of responsibility as
between Buyer and Sellers for certain tax matters following the Closing Date:

                                       13
<PAGE>
 
     (a)  Tax Periods Ending on or Before the Closing Date.  Buyer shall prepare
          ------------------------------------------------                      
or cause to be prepared and file or cause to be filed all Tax Returns for the
Acquired Companies for all periods ending on or prior to the Closing Date which
are filed after the Closing Date. Buyer shall permit Davidovich to review and
comment on each such Tax Return described in the preceding sentence prior to
filing and shall make such revisions to such Tax Returns as are reasonably
requested by Davidovich.  Davidovich shall reimburse Buyer for Taxes of the
Acquired Companies with respect to such periods within fifteen (15) days after
payment by Buyer or the Acquired Companies of such Taxes to the extent such
Taxes are not reflected in the reserve for Tax Liability (rather than any
reserve for deferred Taxes established to reflect timing differences between
book and Tax income) shown on the Closing Statement.

     (b)  Tax Periods Beginning Before and Ending After the Closing Date.  Buyer
          --------------------------------------------------------------        
shall prepare or cause to be prepared and file or cause to be filed any Tax
Returns of the Acquired Companies for Tax periods which begin before the Closing
Date and end after the Closing Date in a manner reasonably consistent with past
tax returns.  Buyer shall permit Davidovich to review and comment on each such
Tax Return described in the preceding sentence prior to filing and shall make
such revisions to such Tax Returns as are reasonably requested by Davidovich.
Davidovich shall pay to Buyer within fifteen (15) days after the date on which
Taxes are paid with respect to such periods an amount equal to the portion of
such Taxes which relates to the portion of such Taxable period ending on the
Closing Date to the extent such Taxes are not reflected in the reserve for Tax
Liability (rather than any reserve for deferred Taxes established to reflect
timing differences between book and Tax income) shown on the Closing Statement.
For purposes of this Section, in the case of any Taxes that are imposed on a
periodic basis and are payable for a Taxable period that includes (but does not
end on) the Closing Date, the portion of such Tax which relates to the portion
of such Taxable period ending on the Closing Date shall (x) in the case of any
Taxes other than Taxes based upon or related to income or receipts, be deemed to
be the amount of such Tax for the entire Taxable period multiplied by a fraction
the numerator of which is the number of days in the Taxable period ending on the
Closing Date and the denominator of which is the number of days in the entire
Taxable period, and (y) in the case of any Tax based upon or related to income
or receipts be deemed equal to the amount which would be payable if the relevant
Taxable period ended on the Closing Date.  All determinations necessary to give
effect to the foregoing allocations shall be made in a manner consistent with
prior practice of the Acquired Companies.

     (c)  Refunds and Tax Benefits.  Any Tax refunds that are received by Buyer
          ------------------------                                             
or the Acquired Companies, and any amounts credited against Tax to which Buyer
or the Acquired Companies become entitled, that relate to Tax periods or
portions thereof ending on or before the Closing Date shall be for the account
of Sellers, and Buyer shall pay over to Sellers on a Pro Rata Basis any such
refund or the amount of any such credit within fifteen (15) days after receipt
or entitlement thereto, unless Sellers have received credit therefor on the
Closing Statement. In addition, to the extent that a claim for refund or a
proceeding results in a payment or credit against Tax by a taxing authority to
the Buyer or the Acquired Companies

                                       14
<PAGE>
 
of any amount accrued on the Closing Statement, the Buyer shall pay such amount
to Sellers on a Pro Rata Basis within fifteen (15) days after receipt or
entitlement thereto.

     (d)  Cooperation on Tax Matters.
          -------------------------- 

          (i)  Buyer and Sellers shall cooperate fully, as and to the extent
     reasonably requested by the other party, in connection with the filing of
     Tax Returns pursuant to this Section and any audit, litigation or other
     proceeding with respect to Taxes. Such cooperation shall include the
     retention and (upon the other party's request) the provision of records and
     information which are reasonably relevant to any such audit, litigation or
     other proceeding and making employees available on a mutually convenient
     basis to provide additional information and explanation of any material
     provided hereunder.  Buyer and Sellers agree (A) that Buyer will cause the
     Acquired Companies to retain all books and records with respect to Tax
     matters pertinent to the Acquired Companies relating to any taxable period
     beginning before or including the Closing Date until the expiration of the
     statute of limitations (and, to the extent notified by Buyer or Sellers,
     any extensions thereof) of the respective taxable periods, and to abide by
     all record retention agreements entered into with any taxing authority, and
     (B) to give the other party reasonable written notice prior to
     transferring, destroying or discarding any such books and records and, if
     the other party so requests, Buyer will cause the Acquired Companies to
     allow the other party to take possession of such books and records.

          (ii) Buyer and Sellers further agree, upon request, to use their best
     efforts to obtain any certificate or other document from any governmental
     authority or any other Person as may be necessary to mitigate, reduce or
     eliminate any Tax that could be imposed (including, but not limited to,
     with respect to the transactions contemplated hereby).

     (e)  Any dispute between the parties regarding the matters set forth in
this Section 2.8 shall be submitted to the Accountants for resolution in
accordance with the procedures set forth in Section 2.7 above.

     2.9  Environmental Escrow
          --------------------

At the Closing, Buyer will pay $1,375,000 to the Escrow Agent to be held and
disbursed pursuant to the Environmental Escrow Agreement.  Buyer shall have no
claim against Davidovich for breach of any representation or warranty related to
the matters specified on Exhibit A to the Environmental Escrow Agreement, other
than the right which Buyer has under the Escrow Agreement to apply the escrowed
funds to correct and address the matters specified on Exhibit A.  Prior to
Closing, Buyer and Sellers will mutually agree on the independent consultant to
serve as contemplated by the Environmental Escrow Agreement.

     3.6  Title to Properties; Encumbrances
          ---------------------------------

Part 3.6 of the Disclosure Letter contains a complete and accurate list of all
real and immoveable property, real property leaseholds, or other interests
therein owned by any Acquired Company.  The Acquired Companies own (with good
and indefeasible title in the case of real and immoveable property, subject only

assets (whether real and immoveable, personal and moveable, or mixed and whether
tangible or intangible) that they purport to own located in the facilities owned
or operated by the Acquired Companies or reflected as owned in the books and
records of the Acquired Companies, including all of the properties and assets
reflected in the Interim Balance Sheets and including all Intellectual Property
Assets (as hereinafter defined) (except for (i) assets held under capitalized
leases disclosed or not required to be disclosed in Part 3.6 of the Disclosure
Letter, (ii) personal and moveable property sold since the dates of the Interim
Balance Sheets, as the case may be, in the Ordinary Course of Business and (iii)
certain real and immoveable property and improvements thereon located in Keller,
Texas and identified in Part 3.6 of the Disclosure Letter as sold prior to
Closing, and all of the properties and assets purchased or otherwise acquired by
the Acquired Companies since the date of the Interim Balance Sheets (except for
personal and moveable property acquired and sold since the date of the Interim
Balance Sheets in the Ordinary Course of Business and consistent with past
practice), which subsequently purchased or acquired properties and assets (other
than inventory and short-term investments) are listed in Part 3.6 of the
Disclosure Letter.  All material properties and assets reflected in the Interim
Balance Sheets and all Intellectual Property Assets are free and clear of all
Encumbrances except, with respect to all such properties and assets, (a)
mortgages, hypothecs or security interests shown on the Interim Balance Sheets
as securing specified liabilities or obligations, (b) mortgages, hypothecs or
security interests incurred in connection with the purchase of property or
assets after the date of the Interim Balance Sheets (such mortgages, hypothecs
and security interests being limited to the property or assets so acquired), (c)
liens for current taxes not yet due or the validity of which is being contested
in good faith by appropriate legal proceedings, (d) statutory liens (including
materialmen's, mechanic's, repairmen's, landlord's, and other similar liens)
arising in connection with the Ordinary Course of Business securing payments not
yet due and payable or, if due and payable, the validity of which is being
contested in good faith by appropriate legal proceedings, and (e) such
imperfections or irregularities of title, if any, as (A) are not substantial in
character, amount, or extent and do not materially detract from the value of the
property subject thereto, (B) do not materially interfere with either the
present or intended use of such property, and (C) do not, individually or in the
aggregate, materially interfere with the conduct of the Acquired Companies
normal operations or otherwise have a Material Adverse Effect.

     3.7  Condition and Sufficiency of Assets
          -----------------------------------

Except as disclosed in Part 3.7 of the Disclosure Schedule, to the knowledge of
Management, the buildings, plants, structures, and equipment of the Acquired
Companies are structurally sound, are in good operating condition and repair,
and are adequate for the uses to which they are being put, and none of such
buildings, plants, structures, or equipment is in need of maintenance or repairs
(except for ordinary, routine maintenance and repairs). The building, plants,
structures, and equipment of the Acquired Companies are sufficient for the
continued conduct of the Acquired Companies' businesses after the Closing in
substantially the same manner as conducted prior to the Closing.

     3.8  Accounts Receivable
          -------------------

All accounts receivable of the Acquired Companies that are reflected on the
Interim Balance Sheets or on the Closing Statement and the accounting records of
the Acquired Companies as of the Closing Date (collectively, the "Accounts
Receivable") represent or will represent valid obligations arising from sales
actually made or services actually performed in the Ordinary Course of Business.
Unless paid prior to the Closing Date, the Accounts Receivable are or will be as
of the Closing Date current and collectible net of the reserves, if any, shown
on the Closing Statement (which reserves, if any, are adequate consistent with
past practice and will not represent a material adverse change in the
composition of such Accounts Receivable in terms of aging).  Subject to such
reserves, if any, each of the Accounts Receivable either has been or will be
collected in full, without any set-off, within 180 days after the day on which
it first becomes due and payable.  There is no contest, claim, or right of set-
off, other than returns in the Ordinary Course of Business, under any Contract
with any obligor of an Accounts Receivable relating to the amount or validity of
such Accounts Receivable.  Part 3.8 of the Disclosure Letter contains a complete
and accurate list of all Accounts Receivable as of the date of the Interim
Balance Sheets, which list sets forth the aging of such Accounts Receivable.

     3.9  Inventory
          ---------

Except as stated in Part 3.4 of the Disclosure Letter: All inventory of the
Acquired Companies, whether or not reflected in the Interim Balance Sheets,
consists of a quality and quantity useable and salable in the Ordinary Course of
Business. Inventories will be valued in accordance with GAAP applied on a
consistent basis, net of any reserves required in accordance with GAAP. Raw
materials, work in process and finished goods will be valued at the lower of
cost or market, with cost being calculated on an average cost basis, the lower
of cost or market test for raw materials and work in process will be determined
on a FIFO basis using the most current invoice and the next prior invoice(s)
unit all pounds of raw material and WIP have been valued. The amount of overhead
and labor added to work in process and finished goods is based on the direct
cost method where all material costs directly related to the production process
along with direct labor, depreciation, utilities, and repairs and maintenance
are capitalized into inventory and is

                                       20
<PAGE>
 
consistent with the prior periods. Non-prime inventory will be stated at the net
realizable value, using the average sales price of the last 90 days actual sales
of the specific product. The Acquired Companies will try to sell all non-prime
inventory prior to Closing.

     3.10  No Undisclosed Liabilities
           --------------------------

Except as set forth in Part 3.10 of the Disclosure Letter, the Acquired
Companies have no liabilities or obligations of any nature (whether known or
unknown and whether absolute, accrued, contingent, or otherwise) except for
liabilities or obligations reflected or reserved against in the Interim Balance
Sheets and current liabilities incurred in the Ordinary Course of Business since
the respective dates thereof which, if still outstanding on the Closing  Date,
will be reflected in the Closing Statement; provided, however, the foregoing
representation does not apply to or cover any liabilities or obligations that
are generally the subject of any other representation or warranty made by
Davidovich in this Agreement, whether or not such liabilities or obligations
would be required to be disclosed under the express terms of such other
representation or warranty.

     3.11  Taxes
           -----

     (a) Except as set forth in Part 3.11 of the Disclosure Letter, the Acquired
Companies have filed or caused to be filed on a timely basis since February 25,
1994 all Tax Returns that are or were required to be filed by or with respect to
any of them, either separately or as a member of a group of corporations,
pursuant to applicable Legal Requirements.  The Acquired Companies have paid, or
made provision for the payment of, all Taxes that have or may have become due
pursuant to those Tax Returns or otherwise (since February 25, 1994), or
pursuant to any assessment received by Sellers or any Acquired Company, except
such Taxes, if any, as are listed in Part 3.11 of the Disclosure Letter and are
being contested in good faith and as to which adequate reserves (determined in
accordance with GAAP) have been provided in the Interim Balance Sheets.  Each of
the Acquired Companies has paid adequate and timely installments of taxes.

     (b) Part 3.11 of the Disclosure Letter contains a complete and accurate
list of all audits of all Tax Returns filed since February 25, 1994.  All
deficiencies proposed as a result of such audits have been paid, reserved
against, settled, or, as described in Part 3.11 of the Disclosure Letter, are
being contested in good faith by appropriate proceedings.  Part 3.11 of the
Disclosure Letter describes all adjustments to the United States federal income
Tax Returns and Canadian (federal and provincial) income Tax Returns filed by
any Acquired Company or any group of corporations including any Acquired Company
for all taxable years since February 25, 1994, and the resulting deficiencies
proposed by the IRS or Canadian Revenue Authorities, as the case may be.  Except
as described in Part 3.11 of the Disclosure Letter, neither Seller nor any
Acquired Company has given or been requested to give waivers or extensions (or
is or would be subject to a waiver or extension given by any other Person) of
any statute of limitations relating to the payment of Taxes of any Acquired
Company or 

                                       21
<PAGE>
 
for which any Acquired Company may be liable for any Tax Return filed after
February 25, 1994.

     (c) The charges, accruals, and reserves with respect to Taxes on the
respective books of each Acquired Company are adequate (determined in accordance
with GAAP) and are at least equal to that Acquired Company's liability for Taxes
for any Tax Return filed after February 25, 1994.  To Management's Knowledge,
there exists no proposed tax assessment against any Acquired Company except as
disclosed in the Interim Balance Sheets or in Part 3.11 of the Disclosure Letter
for any Return filed after February 25, 1994.  No consent to the application of
Section 341(f)(2) of the IRC or any similar provision of the ITA has been filed
with respect to any property or assets held, acquired, or to be acquired by any
Acquired Company.  All Taxes that any Acquired Company is or was required by
Legal Requirements to withhold or collect after February 25, 1994 have been duly
withheld or collected and, to the extent required, have been paid to the proper
Governmental Body or other Person.

     (d) All Tax Returns filed since February 25, 1994 by (or that include on a
consolidated basis) any Acquired Company are true, correct, and complete in all
material respects.  There is no tax sharing agreement that will require any
payment by any Acquired Company after the date of this Agreement.  During the
consistency period (as defined in Section 338(h)(4) of the IRC or any equivalent
provision of the ITA with respect to the sale of the Shares to Buyer), no
Acquired Company or target affiliate (as defined in Section 338(h)(6) of the IRC
or any equivalent provision of the ITA with respect to the sale of the Shares to
Buyer) has sold or will sell any property or assets to Buyer or to any member of
the affiliated group (as defined in Section 338(h)(5) of the IRC or any
equivalent provision of the ITA) that includes Buyer.  Part 3.11 of the
Disclosure Letter lists all such target affiliates.

     (e) The paid-up capital for tax purposes of 10 shares of common stock, par
value $10.00 per share, of StyroChem International Ltd. is no less than its
stated capital for corporate purposes.

     3.12  No Material Adverse Change
           --------------------------

Except as set forth in Part 3.12 of the Disclosure Letter, since the date of the
Interim Balance Sheets, there has not been any material adverse change in the
business, operations, properties, prospects, assets, or condition of any
Acquired Company that would have a Material Adverse Effect, and, to the
Knowledge of Management, no event has occurred or circumstance exists that may
result in such a Material Adverse Effect.

          ------------

Between the date of this Agreement and the Closing Date, each Seller will
promptly notify Buyer in writing if such Seller or any Acquired Company becomes
aware of any fact or condition that causes or constitutes a Breach of any of
Sellers' representations and warranties as of the date of this Agreement, or if
such Seller or any Acquired Company becomes aware of the occurrence after the
date of this Agreement of any fact or condition that would (except as expressly
contemplated by this Agreement) cause or constitute a Breach of any such
representation or warranty had such representation or warranty been made as of
the time of occurrence or discovery of such fact or condition.  Should any such
fact or condition require any change in the Disclosure Letter if the Disclosure
Letter were dated the date of the occurrence or discovery of any such fact or
condition, Sellers will promptly deliver to Buyer a supplement to the Disclosure
Letter specifying such change.  During the same period, each Seller will
promptly notify Buyer of the occurrence of any Breach of any covenant of Sellers
in this Section 5 or of the occurrence of any event that may make the
satisfaction of the conditions in Section 7 impossible or unlikely.  No
supplement to the Disclosure Letter may be delivered by Sellers after the

any inquiries or proposals from, discuss or negotiate with, provide any non-
public information to, or consider the merits of any unsolicited inquiries or
proposals from, any Person (other than Buyer) relating to any transaction
involving the sale of the business or assets (other than in the Ordinary Course
of Business) of 

                                       47

Between the date of this Agreement and the Closing Date, Buyer will promptly
notify Davidovich in writing if Buyer becomes aware of any fact or condition
that causes or constitutes a Breach of any of Buyer's representations and
warranties as of the date of this Agreement, or if Buyer becomes aware of the
occurrence after the date of this Agreement of any fact or condition that would
(except as expressly contemplated by this Agreement) cause or constitute a
Breach of any such representation or warranty had such representation or
warranty been made as of the time of occurrence or discovery of such fact or

     6A.3 Accounts receivable of the Acquired Companies which are reflected in
the Closing Statement as collectible and not reserved against, and which are in

doing business with the account debtors and (ii) Buyer has received payment from
Davidovich for such accounts receivable by way of indemnification with respect
to the breach of the representation and warranty made by Davidovich in Section
3.8 hereof.  Davidovich will attempt to collect any accounts receivable assigned

          ---------------------

                                       53
<PAGE>
 
Each party's right of termination under Section 9.1 is in addition to any other
rights it may have under this Agreement and the exercise of a right of
termination will not be an election of remedies; provided, however, the
foregoing shall not apply in the event of the non-satisfaction of the conditions
in Sections 7.1 or 8.1 (unless the Breach of the representation or warranty
which caused such non-satisfaction was intentional or fraudulent), in which case
the parties agree that termination of this Agreement shall be the sole and
exclusive remedy of either party prior to the Closing due to the non-
satisfaction of the conditions set forth in Sections 7.1 or 8.1.  If this
Agreement is terminated pursuant to Section 9.1, all further obligations of the
parties under this Agreement will terminate, except that the obligations in
Sections 11.1 and 11.3 will survive; provided, however, that if this Agreement
is terminated by a party because of the Breach of the Agreement by the other
party or because one or more of the conditions to the terminating party's

capable of being acquired) at any time, whether before or after the execution
and delivery of this Agreement or the Closing Date, with respect to the accuracy
or inaccuracy of or compliance with, any such representation, warranty,
covenant, or obligation.  The waiver of any condition based on the accuracy of
any representation or warranty, or on the performance of or compliance with any
covenant or obligation, will not affect the right to indemnification, payment of
Damages, or other remedy based on such representations, warranties, covenants,
and obligations.

claim specifying the factual basis of that claim in reasonable detail to the
extent then known by Buyer, except that (i) any claims with respect to Sections
3.8 and 3.9 shall be made in connection with the determination of the Adjustment

the Closing Date, Sellers notify Buyer of a claim specifying the factual basis
of that claim in reasonable detail to the extent then known by Sellers, except
that a claim for indemnification or reimbursement not based upon any

     (a)  Davidovich will not have liability (for indemnification or otherwise)
with respect to the matters described in Section 10.3 until the total of all
Damages with respect to such matters exceeds $350,000 (the "Basket') and then
only for the amount by which such Damages exceed the Basket.  Damages arising
from a single matter will not subject Davidovich to such liability for
indemnification, or be counted toward the Basket, unless they exceed $10,000,
but if they exceed $10,000 for a single matter, the entire amount of Damages for
such matter shall be counted toward the Basket and will subject Davidovich to
liability for indemnification to the extent the Basket is exceeded.

                                       56
<PAGE>
 
     10.7 Limitations on Amount--Buyer
          ----------------------------

Buyer will have no liability (for indemnification or otherwise) with respect to
the matters described in clause (a) or (b) of Section 10.4 until the total of
all Damages with respect to such matters exceeds $350,000, and then only for the
amount by which such Damages exceed $350,000.  However,  this Section 10.7 will
not apply to any Breach of any of Buyer's representations and warranties of
which Buyer had Knowledge at any time prior to the date on which such
representation and warranty is made or any intentional Breach by Buyer of any
covenant or obligation, and Buyer will be liable for all Damages with respect to
such Breaches.

     10.8 Procedure for Indemnification--Third Party Claims
          -------------------------------------------------

     (a)  Promptly after receipt by an indemnified party under Section 10.2,
10.3, or 10.4  of notice of the commencement of any Proceeding against it, such
indemnified party will, if a claim is to be made against an indemnifying party
under such Section, give notice to the indemnifying party of the commencement of
such claim, but the failure to notify the indemnifying party will not relieve
the indemnifying party of any liability that it may have to any indemnified
party, except to the extent that the indemnifying party demonstrates that the
defense of such action is prejudiced by the indemnifying party's failure to give
such notice.

     (b)  If any Proceeding referred to in Section 10.8(a) is brought against an
indemnified party and it shall give written notice to the indemnifying party of
the commencement thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it may wish, to assume the defense
thereof with counsel reasonably satisfactory to such indemnified party.  If the
indemnifying party elects to assume the defense of such action, the indemnified
party shall have the right to employ separate counsel at its own expense and to
participate in the defense thereof.  If the indemnifying party elects not to
assume (or fails to assume) the defense of such action, the indemnified party
shall be entitled to assume the defense of such action with counsel of its own
choice, at the expense of the indemnifying party.  If the action is asserted
against both the indemnifying party and the indemnified party and there is a
conflict of interests which renders it inappropriate for the same counsel to
represent both the indemnifying party and the indemnified party, the
indemnifying party shall be responsible for paying for separate counsel for the
indemnified party.  If the indemnifying party elects to assume the defense of
such action, (a) no compromise or settlement thereof may be effected by the
indemnifying party without the indemnified party's written consent (which shall
not be unreasonably withheld) unless the sole relief provided is monetary
damages that are paid in full by the indemnifying party and (b) the indemnifying
party shall have no liability with respect to any compromise or settlement
thereof effected without its written consent (which shall not be unreasonably
withheld).  If notice is given to an indemnifying party of the commencement of
any Proceeding and the indemnifying party does not, within ten days after the
indemnified party's notice is given, give notice to the indemnified party of its
election to assume the defense of 

                                       57
<PAGE>
 
such Proceeding, the indemnifying party will be bound by any determination made
in such Proceeding or any compromise or settlement effected by the indemnified
party.

     (c)  Sellers hereby consent to the non-exclusive jurisdiction of any court
in which a Proceeding is brought against any Indemnified Person for purposes of
any claim that an Indemnified Person may have under this Agreement with respect
to such Proceeding or the matters alleged therein, and agree that process may be
served on Sellers with respect to such a claim anywhere in the world.

     10.9  Procedure for Indemnification--Other Claims
           -------------------------------------------

A claim for indemnification for any matter not involving a third-party claim may
be asserted by notice to the party from whom indemnification is sought.

     10.10 Limitations of Liability
           ------------------------

The indemnification obligations of the parties hereto pursuant to this Section
10 shall be subject to the following limitations:

     (a)   The amount of Damages required to be paid by any party to indemnify
any other party pursuant to this Section 10 as a result of any claim for
indemnification shall be reduced to the extent of any amounts actually received
by such other party after the Closing Date pursuant to the terms of the
insurance policies (if any) covering such claim, and each party shall pursue
available claims against such insurance policies in good faith.

     (b)  The amount of Damages required to be paid by any party to indemnify
any other party pursuant to this Section 10 as a result of any claim shall be
reduced by the amount of any Tax benefit actually realized by such other party
as a result of such claim, provided that such reduced amount shall be increased
by the amount of any Taxes actually payable by such other party as a result of
the payment to such other party of Damages for such claim (the net reduction is
hereinafter referred to in this paragraph as the "Claim Reduction Amount"). The
Claim Reduction Amount shall be calculated by the indemnified party on a present
value basis using the appropriate applicable federal rate for the month that the
claim will be paid as specified under Section 1274(d) of the IRC. Any factual
assumptions, Tax rate assumptions, assumptions relating to the appropriate
applicable federal rate, or assumptions relating to the appropriate Tax
treatment of a particular item shall be made by the indemnified party. The
indemnified party shall supply to the indemnifying party such information as the
indemnifying party may reasonably request to support the indemnified party's
assumptions and calculations. If the indemnifying party believes that the
overall calculation is unreasonable, the parties shall submit the issue to an
independent public accounting firm of recognized national standing mutually
agreeable to the parties for determination as to whether such calculation is in
fact reasonable on an overall basis. If such firm determines that the
calculation is not reasonable, such firm shall modify whichever assumptions it
deems necessary to make the overall calculation reasonable. The 

                                       58
<PAGE>
 
determinations of such firm shall be final and conclusive as to any dispute
regarding the Claim Reduction Amount. The costs and expenses of such firm in
connection with its determinations pursuant to this paragraph shall be borne
equally by the parties. Each party shall be solely responsible for all other
costs and expenses incurred by such party pursuant to this paragraph.

     (c)   No indemnification shall be required to be made by any indemnifying
party pursuant to this Section 10 with respect to any claims for indemnification
to the extent that the aggregate amount of Damages incurred by the indemnified
party with respect to all such claims (whether asserted, resulting, imposed, or
incurred before, on, or after the Closing Date) exceeds $4,000,000.

     (d)   The indemnification obligations of the parties pursuant to this
Section 10 (including the definition of the term "Damages" as provided herein)
shall be limited to actual and direct damages and shall not, except in the case
of a willful Breach of this Agreement or fraud, include consequential, punitive,
or exemplary damages or damages based on lost profits or lost opportunities.

     10.11 Sole and Exclusive Remedies
           ---------------------------

The parties hereto agree that, in relation to any Breach of any representation,
warranty, covenant, or agreement made or entered into by a party hereto pursuant
to this Agreement or any certificate, instrument, or document delivered pursuant
hereto, the only sole and exclusive relief and remedies available to the other
party hereto in respect of such Breach (regardless of any other rights and
remedies provided by law or in equity) shall be:

     (a)   termination, but only if said termination is expressly permitted
under the provisions of Section 9.1;

     (b)   damages, but only to the extent properly claimable hereunder and as
provided and limited pursuant to this Section 10 and by Section 9.2;

     (c)   specific performance if a court of competent jurisdiction in its
discretion grants the same; and

     (d)   injunctive or declaratory relief if a court of competent jurisdiction
in its discretion grants the same.

The parties hereto hereby expressly (i) waive and forego any other rights and
remedies other than the foregoing, whether provided by law or in equity, and
(ii) agree that no action for termination or rescission, or claiming
repudiation, of this Agreement may be brought or maintained by either party
against the other following the Closing Date no matter how severe, grave, or
fundamental any such Breach may be by one party.  Accordingly, the parties
hereby also expressly waive and forego any and all rights they may possess to
bring any such action.

party.

     11.2 Public Announcements
          --------------------

Any public announcement or similar publicity with respect to this Agreement or
the Contemplated Transactions will be issued, if at all, at such time and in
such manner as Buyer and Davidovich mutually agree.  Unless consented to by the
other party in advance or required by Legal Requirements, prior to the Closing
each party hereto shall, keep this Agreement strictly confidential and may not
make any disclosure of this Agreement to any Person, other than to their
financial advisors, legal counsel, accountants, bankers and others with a "need
to know" in order for the parties to carry out the Contemplated Transactions.
Sellers and Buyer will consult with each other concerning the means by which the
Acquired Companies' employees, customers, and suppliers and others having
dealings with the Acquired Companies will be informed of the Contemplated
Transactions, and Buyer will have the right to be present for any such
communication.

     11.3 Confidentiality
          ---------------

The Buyer's obligations with respect to the confidentiality of all Evaluation

officers, employees, agents, and advisors of Sellers and the Acquired Companies
to maintain in confidence, any written, oral or other information obtained in
confidence from Buyer or any subsidiary of Buyer in connection with this
Agreement on the Contemplated Transactions unless (a) such information is
already known to such party or to others not bound by a duty of confidentiality
or such information becomes publicly available through no fault of such party,
(b) the use of such information is necessary or appropriate in making any filing
or obtaining any consent or approval required for the consummation of the
Contemplated Transaction, or (c) the furnishing or use of such information is
required by legal proceedings.  If the Contemplated Transactions are not

                                       60

consummated, each party will return or destroy as much of such written

           --------------------------------

Any action or proceeding seeking to enforce any provision of, or based on any
right arising out of, this Agreement may be brought against any of the parties
in the courts of the State of Delaware, County of New Castle, or, if it has or
can acquire jurisdiction, in the United States District Court for the District
of Delaware, and each of the parties consents to the jurisdiction of such courts
(and of the appropriate appellate courts) in any such action or proceeding and
waives any objection to venue laid therein.  Process in any action or proceeding
referred to in the preceding sentence may be served on any party anywhere in the
world.

     11.6  Further Assurances
           ------------------

The parties agree (a) to furnish upon request to each other such further
information, (b) to execute and deliver to each other such other documents, and

documents referred to in this Agreement.

     11.7  Waiver
           ------

The rights and remedies of the parties to this Agreement are cumulative and not
alternative. Neither the failure nor any delay by any party in exercising any
right, power, or privilege under this Agreement or the documents referred to in
this Agreement will operate as a waiver of such right, power, or privilege, and
no single or partial exercise of any such right, power, or privilege will
preclude any other or further exercise of such right, power, or privilege or the
exercise of any other right, power, or privilege.  To the maximum extent
permitted by applicable law, (a) no claim or right arising out of this Agreement
or the documents referred to in this Agreement can be discharged by one party,
in whole or in part, by a waiver or renunciation of  the claim or right unless
in writing signed by the other party; (b) no waiver that may be given by a party
will be applicable except in the specific instance for which it is given; and
(c) no notice to or demand on one party will be deemed to be a waiver of any
obligation of such party or of the right of the party giving such notice or
demand to take further action without notice or demand as provided in this
Agreement or the documents referred to in this Agreement.

     11.8  Entire Agreement and Modification
           ---------------------------------

to its subject matter and constitutes (along with the documents referred to in
this Agreement) a complete and exclusive statement of the terms of the agreement
between the parties with respect to its subject matter.  This Agreement may not
be amended except by a written agreement executed by the party to be charged
with the amendment.

     11.9  Disclosure Letter
           -----------------

     (a) Except as otherwise provided in the Disclosure Letter, the disclosures
in the Disclosure Letter, and those in any supplement thereto, must relate only
to the representations and warranties in the Section of the Agreement to which
they expressly relate and not to any other representation or warranty in this
Agreement.

     (b) In the event of any inconsistency between the statements in the body of
this Agreement and those in the Disclosure Letter, and those in any supplement
thereto, (other than an exception expressly set forth as such in the Disclosure

Agreement will control.

     11.10 Assignments, Successors, and No Third-Party Rights

Neither party may assign any of its rights under this Agreement without the
prior consent of the other parties, which will not be unreasonably withheld,
except that Buyer may assign any of its rights under this Agreement to any
Subsidiary of Buyer, provided, however, that no such assignment shall be
effective to release or discharge Buyer from any of its obligations or
liabilities hereunder.  Subject to the preceding sentence, this Agreement will
apply to, be binding in all respects upon, and inure to the benefit of the
successors and permitted assigns of the parties.  Nothing expressed or referred
to in this Agreement will be construed to give any Person other than the parties
to this Agreement any legal or equitable right, remedy, or claim under or with
respect to this Agreement or any provision of this Agreement.  Except as
otherwise expressly provided in Section 10, this Agreement and all of its
provisions and conditions are for the sole and exclusive benefit of the parties
to this Agreement and their successors and assigns.

           ------------

of competent jurisdiction, the other provisions of this Agreement will remain in
full force and effect.  Any provision of this Agreement held invalid or
unenforceable only in part or degree will remain in full force and effect to the
extent not held invalid or unenforceable.

11.  Any refund due which will be received by any of the Acquired Companies for

              ------------

business transacted in connection with the Transferred Assets, and, except as
otherwise provided in this Agreement, all obligations accruing in connection
with the Transferred Assets and Assumed Liabilities, shall be for the account of
the Partnership.

     1.7  Post-Closing Adjustments.
          ------------------------

          (a) The value of the inventory (including raw materials, work in
process, finished goods, spare parts, supplies and stores inventory) contributed
by James River on the Closing Date is estimated to be Eight Million Three
Hundred Thousand Dollars ($8,300,000). As provided in Section 1.3(b), the
Payment shall take into account any Inventory Deficiency determined in
accordance with Section 1.7(b) below.

          (b)  Inventory Level Adjustment.
               -------------------------- 

               (1) The Partnership caused its auditors, on November 18 and 19,
1995, to conduct a physical inventory of the inventory contributed by James
River pursuant to Section 1.1(b) of the Agreement, which physical inventory the
Partnership shall roll forward to the Closing Date (as rolled forward, the "JR
Inventory"). As promptly as practical, but in any event not more than thirty
(30) days after the Closing, the Partnership shall cause its auditors to
prepare, on the basis of such physical inventory and the rolling forward of such
physical inventory, and deliver to James River a draft of a statement of the "JR
Inventory Value" as of the commencement of business on the Closing Date (the
"Preliminary Closing Statement"). "JR Inventory Value" shall mean the value of
the JR Inventory on hand as of the Closing Date calculated as set forth in this
Section 1.7(b). JR Inventory on hand as of the Closing Date, as determined by
the physical inventory and rolling forward of the physical

                                      -4-
<PAGE>
 
inventory referred to above, will include items which have historically been
carried on the books of James River and held for sale in the ordinary course of
James River's business. Raw materials, WIP and finished goods inventory will be
valued at the lower of cost or market determined in accordance with generally
accepted accounting principles applied on a consistent basis.  Cost for raw
materials, WIP and finished goods will be calculated to reflect raw material
prices as of the Closing Date.  Supplies, store and spare parts will be valued
at cost as of the Closing Date.  Finished goods inventory will be reduced for
obsolete, slow-moving or damaged inventory.  Spare parts will be reduced for
obsolete spare parts.  The use of the term "slow moving" with respect to
inventory shall mean all inventory in excess of the most recent total of twelve
(12) months' external customer shipments in cases before the Closing Date, which
slow moving inventory shall be valued at fifty percent (50%) of cost. The use of
the term "obsolete" with respect to inventory shall mean all inventory where the
most recent total of twelve (12) months before the Closing Date for all external
customer shipments in cases is zero, except for newly introduced products, which
obsolete inventory shall be valued at zero.  The use of the term "damaged" with
respect to inventory shall mean all inventory contributed by James River which
is ripped, torn, defaced or squashed, which damaged inventory shall be valued at
zero.  The term "obsolete" with respect to spare parts shall mean those spare
parts which are no longer used in the production process, which obsolete spare
parts shall be valued at zero.

               (2) During the ten (10) days following the receipt by James River
of the draft of the Preliminary Closing Statement and the report of the
Partnership's auditors with respect thereto, James River shall be permitted to
review the working papers of the Partnership's auditors relating to the draft of
the Preliminary Closing Statement and shall have such access to the
Partnership's personnel as may be reasonably necessary to permit it to review in
detail the manner in which the draft was prepared. Before the end of such ten
(10) day period, James River shall give any comments or objections it has with
respect to the draft of the Preliminary Closing Statement to the Partnership.
Such comments or objections, insofar as they relate to the valuation of the JR
Inventory, shall be resolved without regard to any materiality standard, and the
Final Closing Statement delivered to James River pursuant to the provisions of
the next paragraph shall reflect such resolution.

               (3) Within ten (10) days after the expiration of such ten-day
period described in the preceding paragraph, the Partnership shall deliver to
James River a Final Closing Statement (the "Final Closing Statement")
accompanied by a definitive report of the Partnership's auditors with respect
thereto. Within five (5) business days after receipt of such Final Closing
Statement and report, James River shall deliver a letter to the Partnership
stating whether they concur with such report and their exceptions thereto, if
any, together with the reasons therefor. If such objections cannot be resolved
between the Partnership and James River within five (5) business days after
delivery of such letter to the Partnership by James River, the question or
questions in dispute shall then be submitted, as soon as practicable, to a
mutually acceptable firm of independent public accountants of nationally
recognized standing, the decision of which as to such question or questions in
dispute shall be made within ten (10) days thereafter and shall be final and
binding upon the parties hereto.

<PAGE>
 
               (4) If the Final Closing Statement, after the resolution of all
disputes, indicates that the value of the JR Inventory is less than Eight
Million Three Hundred Thousand Dollars ($8,300,000) ("Inventory Deficiency"),
the Partnership shall amend the $4,400,000 Note to deduct from the payments due
thereunder the amount of such Inventory Deficiency.

               (5) The fees of James River (including the fees of any auditors
independently retained by James River) incurred in connection with the
preparation of the Preliminary and Final Closing Statements shall be reimbursed
by the Partnership in accordance with Section 1.8 below.  The fees of any
independent accounting firm appointed pursuant to Paragraph (3) of this Section
1.7(b) shall be paid one-half by the Partnership and one-half by James River.

     1.8  Reimbursement of Expenses. The Partnership shall reimburse James
          -------------------------                                       
River for all fees and expenses incurred by James River for its legal counsel,
accountants (for fees associated with conducting physical inventories and
preparing inventory valuations and financial statements in connection with the
formation of the Partnership and excluding fees incurred in connection with the
consummation of the transactions contemplated by  that certain Asset Purchase
Agreement, dated as of October 31, 1995, among WinCup, Benchmark Holdings, Inc.
and James River) and investment bankers, in connection with the negotiation,
documentation and consummation of the transactions contemplated by this
Agreement and the other documents executed in connection herewith.  Attached
hereto as Schedule 1.8 is an itemization of all such fees and expenses paid or
estimated to be due by James River, all of which are deemed to be reasonable.
The Partnership shall reimburse James River for all such fees and expenses as
promptly as practicable after receipt by the Partnership of sufficient evidence
supporting the payment by James River of such fees and expenses.  The estimated
amounts listed on Schedule 1.8 shall be adjusted from time to time after the
Closing, either upward or downward, to the extent required to reflect the actual
fees and expenses paid by James River and reimburseable pursuant to this Section
1.8.  To the extent permitted under the Capital Expenditure Loans (as defined in
that certain Revolving Credit, Term Loan and Security Agreement, dated as of the
date hereof, among the Partnership, WinCup and The Bank of New York Commercial
Corporation (as Lender and as Agent)), the Partnership shall draw on amounts
from such loan and pay such drawed amounts to James River to reimburse James
River for all capital expenditures incurred by James River within ninety (90)
days prior to Closing and related to any engineering projects undertaken for the
benefit of the Partnership and its business.

     1.9  Retention of Books and Records; Availability of Employees.
          --------------------------------------------------------

James River will retain and maintain, in an organized and retrievable manner,
all material documents and records pertaining to the Foam Business for periods
prior to the Closing Date. James River agrees to make available to the
Partnership all such documents and records, including, without limitation, such
documents and records as the Partnership shall reasonably require to compile the
previous three years audited financials, as well as such employees of James
River, as may be reasonably requested by the Partnership in order to comply with
all

                                      -6-
<PAGE>
 
pertinent requests from the Internal Revenue Service and state taxing
authorities which relate to periods prior to the Closing or as the Partnership
otherwise deems necessary to the efficient operation of the Partnership's
business, which shall be deemed to include any refinancing of the Partnership's
indebtedness.

and assessments) shall be subject to the following terms and conditions:

               (i)   The indemnified party shall give prompt written notice to

of this Article VI, which notice shall state the nature and basis of the
assertion and the amount thereof, to the extent known, provided, however, that

indemnifying party has sufficient financial resources to defend and fulfill its
indemnification obligation with respect to the Legal Action; (c) if the Legal
Action involves other than money damages and seeks injunctive or other equitable
relief; or (d) if a judgment against the indemnified party in the Legal Action

precedent which will be materially adverse to the best interest of its
continuing business, the indemnifying party shall not be entitled to assume the
defense of the Legal Action and the defense shall be handled by the indemnified
party.  If the defense of the Legal Action is handled by the indemnified party
under the provisions of this subsection, the indemnifying party shall pay all
legal and other expenses reasonably incurred by the indemnified party in
conducting such defense;

                (iv)  In any Legal Action initiated by a third party and

settlement of any claim without the written consent of the indemnified party,
which consent shall not be unreasonably withheld. Without limiting the
generality of the foregoing, it shall not be deemed unreasonable to withhold
consent to a settlement involving injunctive or other equitable relief against
the indemnified party or its assets, employees or business, or relief which the
indemnified party reasonably believes could establish a custom or precedent
which will be materially adverse to the best interests of its continuing
business.

to indemnification thereunder only for the aggregate amount of such liability in
excess of $50,000 or (2) except as set forth in clause (1), unless and to the
extent the aggregate amount of liability under such Section (including any

investigation by any party and shall not terminate until eighteen (18) months
after the Closing Date.   With respect to any claim asserted by the Partnership
with respect to the liabilities retained by James River pursuant to Section
1.3(f), the right of indemnification provided for in Section 6.1(a)(iv) shall
survive for a period of five (5) years from the Closing Date.  Notwithstanding
the provisions of the preceding sentences, any representation or warranty in
respect of which indemnification may be sought under Section 6.l(a)(i) or
6.1(b)(i) and any claim in respect of which indemnification may be sought
pursuant to Section 6.1(a)(iii) or 6.1(a)(iv) shall survive the applicable
termination date set forth in the preceding sentences if written notice, given
in good faith, of a specific breach thereof is given to the indemnifying party
on or before such termination date, whether or not liability has actually been
incurred.

<PAGE>
 
          (b)  Inventory Level Adjustment.
               --------------------------

               (1) The Partnership caused its auditors, on November 18 and 19,
1995, to conduct a physical inventory of the inventory contributed by WinCup
pursuant to Section 1.1(b) of the Agreement, which physical inventory the
Partnership shall roll forward to the Closing Date (as rolled forward, the
"WinCup Inventory"). As promptly as practical, but in any event not more than
thirty (30) days after the Closing, the Partnership shall cause its auditors to
prepare, on the basis of such physical inventory and the rolling forward of such
physical inventory, and deliver to WinCup a draft of a statement of the "WinCup
Inventory Value" as of the commencement of business on the Closing Date (the
"Preliminary Closing Statement"). "WinCup Inventory Value" shall mean the value
of the WinCup Inventory on hand as of the Closing Date calculated as set forth
in this Section 1.7(b). WinCup Inventory on hand as of the Closing Date, as
determined by the physical inventory and rolling forward of the physical
inventory referred to above, will include items which have historically been
carried on the books of WinCup and held for sale in the ordinary course of
WinCup's business. Raw materials, WIP and finished goods inventory will be
valued at the lower of cost or market determined in accordance with generally
accepted accounting principles applied on a consistent basis. Cost for raw
materials, WIP and finished goods will be calculated to reflect raw material
prices as of the Closing Date. Supplies, store and spare parts will be valued at
cost as of the Closing Date. Finished goods inventory will be reduced for
obsolete, slow-moving or damaged inventory. Spare parts will be reduced for
obsolete spare parts. The use of the term "slow moving" with respect to
inventory shall mean all inventory in excess of the most recent total of twelve
(12) months' external customer shipments in cases before the Closing Date, which
slow moving inventory shall be valued at fifty percent (50%) of cost. The use of
the term "obsolete" with respect to inventory shall mean all inventory where the
most recent total of twelve (12) months before the Closing Date for all external
customer shipments in cases is zero, except for newly introduced products, which
obsolete inventory shall be valued at zero. The use of the term "damaged" with
respect to inventory shall mean all inventory contributed by WinCup which is
ripped, torn, defaced or squashed, which damaged inventory shall be valued at
zero. The term "obsolete" with respect to spare parts shall mean those spare
parts which are no longer used in the production process, which obsolete spare
parts shall be valued at zero.

               (2) During the ten (10) days following the receipt by WinCup of
the draft of the Preliminary Closing Statement and the report of the
Partnership's auditors with respect thereto, WinCup shall be permitted to review
the working papers of the Partnership's auditors relating to the draft of the
Preliminary Closing Statement and shall have such access to the Partnership's
personnel as may be reasonably necessary to permit it to review in detail the
manner in which the draft was prepared. Before the end of such ten (10) day
period, WinCup shall give any comments or objections it has with respect to the
draft of the Preliminary Closing Statement to the Partnership. Such comments or
objections, insofar as they relate to the valuation of the WinCup Inventory,
shall be resolved without regard to any materiality standard, and the Final
Closing Statement delivered to WinCup pursuant to the provisions of the next
paragraph shall reflect such resolution.

                                      -5-
<PAGE>
 
               (3) Within ten (10) days after the expiration of such ten-day
period described in the preceding paragraph, the Partnership shall deliver to
WinCup a Final Closing Statement (the "Final Closing Statement") accompanied by
a definitive report of the Partnership's auditors with respect thereto. Within
five (5) business days after receipt of such Final Closing Statement and report,
WinCup shall deliver a letter to the Partnership stating whether they concur
with such report and their exceptions thereto, if any, together with the reasons
therefor. If such objections cannot be resolved between the Partnership and
WinCup within five (5) business days after delivery of such letter to the
Partnership by WinCup, the question or questions in dispute shall then be
submitted, as soon as practicable, to a mutually acceptable firm of independent
public accountants of nationally recognized standing, the decision of which as
to such question or questions in dispute shall be made within ten (10) days
thereafter and shall be final and binding upon the parties hereto.

               (4) If the Final Closing Statement, after the resolution of all
disputes, indicates that the value of the WinCup Inventory is less than Ten
Million Three Hundred Thousand Dollars ($10,300,000) ("Inventory Deficiency"),
the Partnership shall amend the $1,000,000 Note to deduct from the payments due
thereunder the amount of such Inventory Deficiency.

               (5) The fees of WinCup (including the fees of any auditors
independently retained by WinCup) incurred in connection with the preparation of
the Preliminary and Final Closing Statements shall be reimbursed by the
Partnership in accordance with Section 1.8 below. The fees of any independent
accounting firm appointed pursuant to Paragraph (3) of this Section 1.7(b) shall
be paid one-half by the Partnership and one-half by WinCup.

     1.8  Reimbursement of Expenses. The Partnership shall reimburse WinCup for
          -------------------------
all fees and expenses incurred by WinCup for its legal counsel, accountants (for
fees associated with conducting physical inventories and preparing inventory
valuations and audited financial statements in connection with the formation of
the Partnership and excluding fees incurred in connection with the consummation
of the transactions contemplated by the Asset Purchase Agreement) and Alex.
Brown & Sons, Inc., in connection with the negotiation, documentation and
consummation of the transactions contemplated by this Agreement and the other
documents executed in connection herewith; provided, however, that the
Partnership shall be responsible for the payment of no more than $550,000 of the
fees payable to Alex. Brown & Sons, Inc. for arranging the bank financing
entered into in connection with the transactions contemplated hereby, the
balance of which fees and all other fees payable to Alex. Brown & Sons, Inc.
shall be the sole responsibility of WinCup. Attached hereto as Schedule 1.8 is
an itemization of all such fees and expenses paid or estimated to be due by
WinCup, all of which are deemed to be reasonable. The Partnership shall
reimburse WinCup for all such fees and expenses as promptly as practicable after
receipt by the Partnership of sufficient evidence supporting the payment by
WinCup of such fees and expenses. The estimated amounts listed on Schedule 1.8
shall be adjusted from time to time after Closing, either

                                      -6-
<PAGE>
 
upward or downward, to the extent required to reflect the actual fees and
expenses paid by WinCup and reimburseable pursuant to this Section 1.8. To the
extent permitted under the Capital Expenditure Loans (as defined in that certain
Revolving Credit, Term Loan and Security Agreement, dated as of the date hereof,
among the Partnership, WinCup and The Bank of New York Commercial Corporation
(as Lender and as Agent)), the Partnership shall draw on amounts from such loan
and pay such drawed amounts to WinCup to reimburse WinCup for all capital
expenditures incurred by WinCup within the ninety (90) days prior to Closing and
related to any engineering projects undertaken for the benefit of the
Partnership and its business.


     1.9  Retention of Books and Records; Availability of Employees.
          ---------------------------------------------------------
WinCup will retain and maintain, in an organized and retrievable manner, all
material documents and records pertaining to the Foam Business for periods prior
to the Closing Date.  WinCup agrees to make available to the Partnership all
such documents and records, as well as such employees of WinCup, as may be
reasonably requested by the Partnership in order to comply with all pertinent
requests from the Internal Revenue Service and state taxing authorities which
relate to periods prior to the Closing or as the Partnership otherwise deems
necessary to the efficient operation of the Partnership's business.

     (c)  Third Party Claims. The obligation of an indemnifying party to
          ------------------  
indemnify another party to this Agreement under the provisions of this Article
VI with respect to claims resulting from the assertion of liability by those not
parties to this Agreement (including governmental claims for penalties, fines
and assessments) shall be subject to the following terms and conditions:

               (i)   The indemnified party shall give prompt written notice to
the indemnifying party of any assertion of liability by a third party which
might give rise to a claim for indemnification based on the foregoing provisions
of this Article VI, which notice shall state the nature and basis of the
assertion and the amount thereof, to the extent known, provided, however, that
no delay on the part of the indemnified party in giving notice shall relieve the
indemnifying party of any obligation to indemnify unless (and then solely to the
extent that) the indemnifying party is prejudiced by such delay;

               (ii)  If any action, suit or proceeding (a "Legal Action") is
brought against an indemnified party with respect to which the indemnifying
party may have liability under the foregoing provisions of this Article VI, the
Legal Action shall be defended (such defense to include all proceedings for
appeal or review which counsel for the indemnified party shall deem appropriate)
by the indemnifying party;

               (iii) Notwithstanding the provisions of the previous subsection
of this Agreement, until the indemnifying party shall have assumed the defense
of any such Legal Action, the defense shall be handled by the indemnified party.
Furthermore, (a) if the indemnified party shall have reasonably concluded that
there are likely to be defenses available to the indemnified party that are
different from or in addition to those available to the indemnifying party; 
(b) if the indemnifying party fails to provide the indemnified party

                                      -15-
<PAGE>
 
with evidence reasonably acceptable to the indemnified party that the
indemnifying party has sufficient financial resources to defend and fulfill its
indemnification obligation with respect to the Legal Action; (c) if the Legal
Action involves other than money damages and seeks injunctive or other equitable
relief; or (d) if a judgment against the indemnified party in the Legal Action
will, in the good faith opinion of the indemnified party, establish a custom or
precedent which will be materially adverse to the best interest of its
continuing business, the indemnifying party shall not be entitled to assume the
defense of the Legal Action and the defense shall be handled by the indemnified
party. If the defense of the Legal Action is handled by the indemnified party
under the provisions of this subsection, the indemnifying party shall pay all
legal and other expenses reasonably incurred by the indemnified party in
conducting such defense;

               (iv)  In any Legal Action initiated by a third party and defended
by the indemnifying party (a) the indemnified party shall have the right to be
represented by advisory counsel and accountants, at its own expense, (b) the
indemnifying party shall keep the indemnified party fully informed as to the
status of such Legal Action at all stages thereof, whether or not the
indemnified party is represented by its own counsel, (c) the indemnifying party
shall make available to the indemnified party, and its attorneys, accountants
and other representatives, all books and records of the indemnifying party
relating to such Legal Action and (d) the parties shall render to each other
such assistance as may be reasonably required in order to ensure the proper and
adequate defense of such Legal Action; and

               (v)   In any Legal Action initiated by a third party and defended
by the indemnifying party, the indemnifying party shall not make any settlement
of any claim without the written consent of the indemnified party, which consent
shall not be unreasonably withheld. Without limiting the generality of the
foregoing, it shall not be deemed unreasonable to withhold consent to a
settlement involving injunctive or other equitable relief against the
indemnified party or its assets, employees or business, or relief which the
indemnified party reasonably believes could establish a custom or precedent
which will be materially adverse to the best interests of its continuing
business.

     (d)  Limitations on Indemnification.
          ------------------------------

          (i)  Notwithstanding the foregoing provisions of this Article VI,
WinCup shall not be liable to the Partnership under Section 6.l(a)(i) and the
Partnership shall not be liable to WinCup under Section 6.1(b)(i), (1) with
respect to any single claim, or series of claims arising from a single
occurrence, unless and to the extent the liability under such claim or series of
claims exceeds $50,000, and thereafter the indemnified party shall be entitled
to indemnification thereunder only for the aggregate amount of such liability in
excess of $50,000 or (2) except as set forth in clause (1), unless and to the
extent the aggregate amount of liability under such Section (including any
amounts for which liability is determined under clause (1) above) exceeds
$250,000, and thereafter the indemnified party

("Buyer"), RICHARD DAVIDOVICH, an individual ("Davidovich"), and DUANE, MORRIS &

                                 RECITALS
                                 --------

          WHEREAS, Buyer, Davidovich, James River Paper Company, Inc., Grupo
Industrial Hermes, S.A. de C.V., and the Rosenthal Group (as such term is
defined in the Stock Purchase Agreement) are parties to a Stock Purchase
Agreement, dated as of October 30, 1996 (the "Stock Purchase Agreement"),
pursuant to which Buyer is acquiring all of the outstanding shares of common and

preferred capital stock, of SP Acquisition Co., a Delaware corporation;

          WHEREAS, the Stock Purchase Agreement provides that certain monies
shall be placed into escrow as more fully described herein and that Buyer and

the respective meanings ascribed to such terms in the Stock Purchase Agreement.

          NOW, THEREFORE, the parties hereto, intending to be legally bound,
agree as follows:

                                 AGREEMENT
                                 ---------

investment.

          4.  Termination of Escrow.  This Agreement shall terminate at such

              ------------ 

              5.1  General.  The Escrow Agent shall act as escrow agent and hold

              5.2  Liquidation of Investments.  When necessary to provide funds
                   --------------------------
in order to make any payments required by Section 2, the Escrow Agent shall

              5.3  Limited Duties and Responsibilities.
                   -----------------------------------
                   
                   (a) This Agreement expressly sets forth all the duties of the
Escrow Agent with respect to any and all matters pertinent hereto. No implied
duties or obligations shall be read into this Agreement against the Escrow
Agent. The Escrow Agent, in its capacity as such, shall not be bound by the
provisions of any Agreement among the parties to this Agreement and shall have
no duty to inquire into, or to take into account its knowledge of, the terms and
conditions of any Agreement made or entered into in connection with this

                                       2
<PAGE>
 
Agreement, including without limitation the Stock Purchase Agreement. The Escrow
Agent shall incur no liability whatsoever to Buyer, Davidovich or any other
Seller, except for its own bad faith or willful misconduct in its capacity as
escrow agent.

          (b) The Escrow Agent's sole responsibility upon receipt of any notice
requiring any payment to Buyer or Davidovich on behalf of the Sellers pursuant
to the terms of this Agreement, is to pay the applicable Escrow Fund to Buyer
and/or Davidovich on behalf of the Sellers, as the case may be, and the Escrow
Agent shall have no duty to determine (and shall not be affected by any
knowledge concerning) the validity, authenticity or enforceability of any
specification or certification made in such notice.

     5.4  Reliance on Notices; Court Orders.
          --------------------------------- 

          (a) The Escrow Agent may rely, and shall be protected in acting or
refraining from action, upon any written notice, instruction or request
furnished to it hereunder and believed by it to be genuine and to have been
signed or presented by the proper party or parties.  The Escrow Agent may
conclusively presume that the undersigned have full power and authority to
instruct the Escrow Agent on behalf of Buyer and Sellers, respectively.
Notwithstanding any other provisions herein contained, the Escrow Agent may at
all times act upon and in accordance with the joint written instructions of
Buyer and Davidovich, on behalf of Sellers.  The Escrow Agent shall not be
liable for any act done or omitted by it in accordance with such instructions or
the exercise of its own best judgment or pursuant to the advice of counsel of
its selection.

          (b) If any property subject hereto is at any time attached, garnished
or levied upon under any court order, or in case the payment, assignment,
transfer, conveyance or delivery of any such property shall be stayed or
enjoined by any court order, or in case any order, judgment or decree shall be
made or entered by any court affecting such property or any part thereof, then
and in any of such events the Escrow Agent is authorized, in its sole
discretion, to rely upon and comply with any such order, writ, judgment or
decree which the Escrow Agent is advised by legal counsel of its own choosing is
binding upon it; and if the Escrow Agent complies with any such order, writ,
judgment or decree, it shall not be liable to any of the parties hereto or to
any other person, firm or corporation by reason of such compliance even though
such order, writ, judgment or decree may be subsequently reversed, modified,
annulled, set aside or vacated.

     5.5  Action in Good Faith.  The Escrow Agent shall not be liable for any
          --------------------
action taken by it in good faith and believed by it to be authorized or within
the rights or powers conferred upon it by this Agreement, and may consult with
counsel of its own choice and shall have full and complete authorization and
protection for any action taken or suffered by it hereunder in good faith and in
accordance with the opinion of such counsel.

     5.6  Resignation; Successor Escrow Agent.  The Escrow Agent may resign and
          -----------------------------------
be discharged from its duties or obligations hereunder by giving 30 days advance
written

<PAGE>
 
notice of such resignation to Buyer and Davidovich, specifying a date upon which
such resignation shall take effect, whereupon a successor escrow agent shall be
appointed by Buyer and Davidovich. The Escrow Agent shall be entitled to pay the
Escrow Fund to any successor escrow agent so appointed. If no successor escrow
agent has been appointed as of the effective date specified in the Escrow
Agent's notice of resignation, the Escrow Agent shall be entitled to deliver the
Escrow Fund into federal or state court in the Commonwealth of Pennsylvania and,
upon giving notice to Buyer and Davidovich of such action, shall thereupon be
relieved of all further responsibility hereunder.

          5.7  Indemnification.  Buyer and Davidovich hereby jointly and
               ---------------                                          
severally agree to indemnify the Escrow Agent for, and to hold it harmless
against, any loss, liability, damage or expense incurred without bad faith or
willful misconduct on the part of the Escrow Agent arising out of or in
connection with its entering into and or performing under this agreement,
including the cost and expense (including, but not limited to, attorneys' fees)
of defending itself against any claim or liability.

          5.8  Escrow Agent as Counsel to Buyer.  Davidovich acknowledges that
               --------------------------------                               
he is aware that the Escrow Agent is acting as counsel to Buyer and its
affiliates in connection with the Stock Purchase Agreement, this Agreement and
other matters, and agrees that the Escrow Agent's acting under this Agreement
shall not affect its ability to act as counsel to Buyer and its affiliates in
any matter, including, but not limited to, any claim, action or proceeding with
respect to this Agreement or the disposition of or entitlement to the Escrow
Fund, provided that nothing in this Section 5.8 shall limit, modify or affect
the duties of the Escrow Agent under Section 2.

          5.9  Expenses.  The Escrow Agent shall be entitled to reimbursement
               --------
for expenses incurred by it to employ such legal counsel and other experts as it
may deem necessary to advise it properly in connection with its obligations
hereunder and may rely on the advice of such counsel and may pay them reasonable
compensation therefor.  All fees and expenses of the Escrow Agent and such legal
counsel and other experts shall be borne equally by Buyer and Davidovich.

     NOW, THEREFORE, for good and valuable consideration, the receipt and

                                   AGREEMENT

2.   Confidential Information

or obtained by him, whether before or after the date hereof, is the property of
the Acquired Companies. Therefore, Davidovich agrees that he will not, at any
time, disclose to any unauthorized Persons or use for his own account or for the
benefit of any third party any Confidential Information, whether Davidovich has
such information in his memory or embodied in writing or other physical form,
without Buyer's written consent, unless and to the extent that the Confidential
Information is or becomes generally known to and available for use by the public
other than as a result of Davidovich's fault or the fault of any other Person
bound by a duty of confidentiality to Buyer or the Acquired Companies.
Davidovich agrees to deliver to Buyer at the time of execution of this
Agreement, and at any other time Buyer may request, all documents, memoranda,

<PAGE>
 
photocopies of documents which support or relate to the Disclosure Letter
provided by the Sellers pursuant to the Stock Purchase Agreement.

3.   Noncompetition
     --------------

     As an inducement for Buyer to enter into the Stock Purchase Agreement and
in consideration for the amount to be paid to Davidovich under this Agreement,
Davidovich agrees that:

     (a)   For a period of five (5) years after the Closing:

           (i)  Davidovich will not, directly or indirectly, engage or invest
in, own, manage, operate, finance, control, or participate in the ownership,
management, operation, financing, or control of, be employed by, associate in
business with, or in any manner connected with, lend his credit to, or render
services or advice to, any business whose products or activities include the
manufacture, sale or distribution of expandable polystyrene, foam cups or
containers (hereinafter the "Business"), anywhere within the United States or
Canada; provided, however, that Davidovich may purchase or otherwise acquire up
to (but not more than) one percent (1%) of any class of securities of any
enterprise (but without otherwise participating in the activities of such
enterprise) if such securities are listed on any national or regional securities
exchange or have been registered under Section 12(g) of the Securities Exchange
Act of 1934 and provided further that nothing herein shall prohibit Davidovich
from engaging in a block and shape business, excluding the manufacture of
expandable polystyrene. Davidovich agrees that this covenant is reasonable with
respect to its duration, geographical area, and scope;

           (ii)  Davidovich will not, directly or indirectly, either for himself
or any other Person, solicit the business of any Person known to Davidovich to
be a customer of an Acquired Company, whether or not Davidovich had personal
contact with such Person, with respect to products or activities which compete
in whole or in part with the products or activities of the Company.

     (b)   For a period of two (2) years after the Closing, Davidovich will not,
directly or indirectly, either for himself or any other Person, (A) induce or
attempt to induce any employee of an Acquired Company to leave the employ of
such Acquired Company, (B) in any way interfere with the relationship between an
Acquired Company and any employee of such Acquired Company, (C) employ, or
otherwise engage as an employee, independent contractor, or otherwise, any
employee of an Acquired Company, or (D) induce or attempt to induce any
customer, supplier, licensee, or business relation of an Acquired Company to
cease doing business with such Acquired Company, or in any way interfere with
the relationship between any customer, supplier, licensee, or business relation
of an Acquired Company.

     (c)   In the event of a breach by Davidovich of any covenant set forth in
Subsection 

                                      -3-
<PAGE>
 
3(a) of this Agreement, the term of such covenant will be extended by the period
of the duration of such breach;

     (d)   Davidovich will not, at any time during or after the five (5) year
period, disparage Buyer or the Acquired Companies, or any of their shareholders,
directors, officers, employees, or agents; and

     (e)   Davidovich will, for a period of five (5) years after the Closing,
within ten (10) days after accepting employment with any employer, advise Buyer
of the identity of such employer. Buyer or an Acquired Company may serve notice
upon each such employer that Davidovich is bound by this Agreement and may
furnish each such employer with a copy of this Agreement or relevant portions
thereof.

4.   Compensation
     ------------

     As consideration for the covenants of Davidovich in Sections 2 and 3 of
this Agreement, the Company will pay Davidovich the sum of Four Million Seven
Hundred Sixty Thousand Dollars ($4,760,000) at the Closing of the Stock Purchase
Agreement by wire transfer of immediately available funds to an account
designated by Davidovich.

5.   Remedies
     --------

     If Davidovich breaches the covenants set forth in Sections 2 or 3 of this
Agreement, Buyer and the Acquired Companies will be entitled to the following
remedies:

     (a)  Damages from Davidovich; and

     (b) In addition to their rights to damages and any other rights they may
have, to obtain injunctive or other equitable relief to restrain any breach or
threatened breach or otherwise to specifically enforce the provisions of
Sections 2 and 3 of this Agreement, it being agreed that money damages alone
would be inadequate to compensate the Buyer and the Acquired Companies and would
be an inadequate remedy for such breach.

The rights and remedies of the parties to this Agreement are cumulative and not
alternative.

6.   Successors and Assigns
     ----------------------

     This Agreement will be binding upon Buyer and Davidovich and will inure to
the benefit of Buyer and the Acquired Companies and their affiliates, successors
and assigns and Davidovich and Davidovich's assigns, heirs and legal
representatives.

7.   Waiver
     ------

     The rights and remedies of the parties to this Agreement are cumulative and
not 

                                      -4-
<PAGE>
 
alternative. Neither the failure of, nor any delay by, any party in exercising
any right, power, or privilege under this Agreement will operate as a waiver of
such right, power, or privilege, and no single or partial exercise of any such
right, power, or privilege will preclude any other or further exercise of such
right, power, or privilege or the exercise of any other right, power, or
privilege. To the maximum extent permitted by applicable law, (a) no claim or
right arising out of this Agreement can be discharged by one party, in whole or
in part, by a waiver or renunciation of the claim or right unless in writing
signed by the other party; (b) no waiver that may be given by a party will be
applicable except in the specific instance for which it is given; and (c) no
notice to or demand on one party will be deemed to be a waiver of any obligation
of such party or of the right of the party giving such notice or demand to take
further action without notice or demand as provided in this Agreement.

8.   Governing Law
     -------------

     This Agreement will be governed by the laws of the State of Delaware,
without regard to conflicts of laws principles.

9.   Jurisdiction; Service of Process
     --------------------------------

     Any action or proceeding seeking to enforce any provision of, or based on
any right arising out of, this Agreement may be brought against any of the
parties in the courts of the State of Delaware, County of New Castle, or, if it
has or can acquire jurisdiction, in the United States District Court for the
District of Delaware, and each of the parties consents to the jurisdiction of
such courts (and of the appropriate appellate courts) in any such action or
proceeding and waives any objection to venue laid therein.  Process in any
action or proceeding referred to in the preceding sentence may be served on any
party anywhere in the world.

10.  Severability
     ------------

     Whenever possible, each provision and term of this Agreement will be
interpreted in a manner to be effective and valid but if any provision or term
of this Agreement is held to be prohibited or invalid, then such provision or
term will be ineffective only to the extent of such prohibition or invalidity,
without invalidating or affecting in any manner whatsoever the remainder of such
provision or term or the remaining provisions or terms of this Agreement.  If
any of the covenants set forth in Section 3 of this Agreement are held to be
unreasonable, arbitrary, or against public policy, such covenants will be
considered divisible with respect to scope, time, and geographic area, and in
such lesser scope, time and geographic area, will be effective, binding and
enforceable against Davidovich.

11.  Counterparts
     ------------

     This Agreement may be executed in one or more counterparts, each of which
will be deemed to be an original copy of this Agreement and all of which, when
taken together, will 

                                      -5-

be deemed to constitute one and the same agreement.

                               SUBLEASE AGREEMENT
                               ------------------


       THIS SUBLEASE AGREEMENT ("Sublease") is made as of the 20th day of
January, 1996, between JAMES RIVER PAPER COMPANY, INC., a Virginia corporation
("Sublandlord") and WINCUP HOLDINGS, L.P., a Delaware limited partnership
("Subtenant").

       A.   Hunt Brothers Leasing, a partnership, d/b/a Hunt Plaza ("Landlord"),
as landlord, and Sublandlord, as tenant, entered into that certain Office
Building Lease dated as of November 8, 1989, as amended by First Addendum to
Leases of August, 1992; by Second Addendum to Lease effective April 4, 1994; by
Third Addendum to Lease effective August 24, 1994; and by Fourth Addendum to
Lease effective May 2, 1995 (as further amended, supplemented or otherwise
modified from time to time, the "Prime Lease"), whereby Landlord leased to
Sublandlord certain premises commonly known as 240 Tamal Vista Boulevard, Corte
Madera, California, as more particularly described in the Prime Lease (the
"Premises").  A copy of the Prime Lease is attached hereto as Exhibit A.
                                                              ----------

       B.   Subtenant desires to sublease from Sublandlord, and Sublandlord is
willing to sublease to Subtenant, the Premises upon the terms and conditions set
forth in this Sublease.

                                   AGREEMENT
                                   ---------

       NOW THEREFORE, Sublandlord and Subtenant agree as follows:

       1.   Subleased Premises.  Subject to the terms and conditions set forth
            -------------------                                               
in this Sublease, Sublandlord hereby subleases to Subtenant, and Subtenant
hereby subleases from Sublandlord, the Premises together with all easements,
rights, privileges and interests appurtenant thereto provided for under the
Prime Lease (the "Subleased Premises").

       2.   Term. The term of this Sublease (the "Sublease Term") shall commence
            -----                                                               
on the date hereof (the "Commencement Date") and shall end on June 29, 1998 (the
day before the expiration of the Prime Lease) (the "Expiration Date"), unless
sooner terminated as set forth herein.

       3.   Rent.

          (a) Subtenant, beginning on the Commencement Date and continuing
throughout the Sublease Term, shall pay to Sublandlord a monthly rental for the

Monthly Rental").  Base Monthly Rental shall be paid to Sublandlord at the
address set forth in Paragraph 6 hereof on the first day of every calendar month
during the Sublease Term (each, a "Due Date") without deduction, offset, prior
notice or demand.  If the Commencement Date or the Expiration Date is a day
other than the first day of a calendar month, the first payment of Base Monthly
Rental and/or the last

the number of days contained in such fractional month. Any payment of Base
Monthly Rental made more than seven (7) days after the Due Date with respect to
such payment shall bear interest at the rate of one and one-half percent 
(1-1/2%) per month until paid.

            (b) In addition to Base Monthly Rental, Subtenant shall pay to
Sublandlord as additional rent hereunder ("Additional Rent") all additional rent
and other charges payable from time to time by Sublandlord under the Prime Lease
including, without limitation, Sublandlord's obligations under Sections 22 and
27 of the Prime Lease.  Payment of Additional Rent shall commence on the
Commencement Date and shall be made on the dates provided in, and in all other
respects in accordance with the terms of, the Prime Lease.

       4.   Inspection.  Subtenant shall, at its sole expense, submit to
            -----------

compliance by Subtenant with all of the terms and conditions of the Prime Lease,
including, but not limited to, all laws, ordinances and regulations applicable
to Subtenant in its operations at the Premises, and including, but not limited
to, those concerning environmental matters.  Landlord, Sublandlord and Subtenant
shall be copied on all inspection reports, and, to the extent required by the
Lease, Sublandlord shall require Subtenant to promptly remedy any issues raised
by any such inspection to the satisfaction of Sublandlord in consultation with
Landlord.  Subtenant shall reimburse Sublandlord within thirty (30) days of
receipt of invoice for all costs and expenses incurred by Sublandlord in

otherwise set forth herein all references in the Incorporated Provisions to the
"Lease," the "Premises," "Landlord," and "Tenant" shall be deemed to refer to
this Sublease, the Subleased Premises, Sublandlord and Subtenant, respectively.

            (b) If there shall be any inconsistency between the Incorporated
Provisions and the express provisions of this Sublease, such provisions of this

                               SUBLEASE AGREEMENT
                               ------------------


       THIS SUBLEASE AGREEMENT ("Sublease") is made as of the 20th day of
January, 1996, between JAMES RIVER PAPER COMPANY, INC., a Virginia corporation
("Sublandlord") and WINCUP HOLDINGS, L.P., a Delaware limited partnership
("Subtenant").

       A.   Hunt Brothers Leasing, a partnership, d/b/a Hunt Plaza ("Landlord"),
as landlord, and Sublandlord, as tenant, entered into that certain Plant Lease
dated as of November 8, 1989, as amended by First Addendum to Leases of August,
1992 (as further amended, supplemented or otherwise modified from time to time,
the "Prime Lease"), whereby Landlord leased to Sublandlord certain premises
commonly known as 195 Tamal Vista Boulevard, Corte Madera, California, as more
particularly described in the Prime Lease (the "Premises").  A copy of the Prime
Lease is attached hereto as Exhibit A.
                            ----------

       B.   Subtenant desires to sublease from Sublandlord, and Sublandlord is
willing to sublease to Subtenant, the Premises upon the terms and conditions set
forth in this Sublease.

                                   AGREEMENT
                                   ---------

       NOW THEREFORE, Sublandlord and Subtenant agree as follows:

       1.   Subleased Premises.  Subject to the terms and conditions set forth
            -------------------                                               
in this Sublease, Sublandlord hereby subleases to Subtenant, and Subtenant
hereby subleases from Sublandlord, the Premises together with all easements,
rights, privileges and interests appurtenant thereto provided for under the
Prime Lease (the "Subleased Premises").

       2.   Term. The term of this Sublease (the "Sublease Term") shall commence
            -----                                                               
on the date hereof (the "Commencement Date") and shall end on June 29, 1998 (the
day before the expiration of the Prime Lease) (the "Expiration Date"), unless
sooner terminated as set forth herein.

       3.   Rent.
            -----
 
            (a)   Subtenant, beginning on the Commencement Date and continuing
throughout the Sublease Term, shall pay to Sublandlord a monthly rental for the

Monthly Rental").  Base Monthly Rental shall be paid to Sublandlord at the
address set forth in Paragraph 6 hereof on the first day of every calendar month
during the Sublease Term (each, a "Due Date") without deduction, offset, prior
notice or demand.  If the Commencement Date or the Expiration Date is a day
other than the first day of a calendar month, the first payment of Base Monthly
Rental and/or the last payment of Base Monthly Rental shall be the pro-rata
portion of such rent for the number of days contained in such fractional month.

interest at the rate of one and one-half percent (1-1/2%) per month until paid.

            (b)   In addition to Base Monthly Rental, Subtenant shall pay to
Sublandlord as additional rent hereunder ("Additional Rent") all additional rent
and other charges payable from time to time by Sublandlord under the Prime Lease
including, without limitation, Sublandlord's obligations under Sections 22 and
26 of the Prime Lease.  Payment of Additional Rent shall commence on the
Commencement Date and shall be made on the dates provided in, and in all other
respects in accordance with the terms of, the Prime Lease.

       4.   Inspection.  Subtenant shall, at its sole expense, submit to
            -----------

compliance by Subtenant with all of the terms and conditions of the Prime Lease,
including, but not limited to, all laws, ordinances and regulations applicable
to Subtenant in its operations at the Premises, and including, but not limited
to, those concerning environmental matters.  Landlord, Sublandlord and Subtenant
shall be copied on all inspection reports, and, to the extent required by the
Lease, Sublandlord shall require Subtenant to promptly remedy any issues raised
by any such inspection to the satisfaction of Sublandlord in consultation with
Landlord.  Subtenant shall reimburse Sublandlord within thirty (30) days of

this Sublease, the Subleased Premises, Sublandlord and Subtenant, respectively.

            (b)   If there shall be any inconsistency between the Incorporated
Provisions and the express provisions of this Sublease, such provisions of this
Sublease shall govern, but only as between Sublandlord and Subtenant.

to any specific provisions of the Prime Lease shall mean all terms, covenants,
conditions and provisions of the Prime Lease.

c/o Radnor Holdings Corporation

Radnor, PA  19087
Attention:  Michael T. Kennedy, Chairman

Dear Mr. Kennedy:

     Notwithstanding any language to the contrary in those certain Sublease
Agreements (collectively, the "Subleases"), each dated as of January 20, 1996,
and entered into between James River Paper Company, Inc. ("James River"), and
WinCup Holdings, L.P. ("WinCup L.P."), with respect to the premises located
generally in Corte Madera, California, or any of the Prime Leases referred to
therein, leased from Hunt Brothers Leasing, L.L.C. ("Landlord"), the
undersigned, intending to be legally bound hereby, agrees as follows:

     1.  Notwithstanding any provision to the contrary in the Subleases, WinCup
L.P. shall not be deemed to have assumed, and does not assume, any liabilities
for matters disclosed by any inspections of the Subleased Premises other than as
set forth in (a) Paragraph 2 below and (b) Section 1.3(a) of that certain JR
Capital Contribution Agreement, dated as of January 20, 1996, between WinCup
L.P. and James River (the "JR Contribution Agreement").

     2.  WinCup L.P. shall be required to reimburse James River, within thirty
(30) days of receipt of invoice from James River, for amounts required to be
paid by James River to Landlord (as defined in the Subleases) for costs and
expenses incurred by Landlord in conducting inspections (other than (a)
environmental inspections relating to "Retained Liabilities", as hereinafter
defined, and as contemplated in Paragraph 8 of that certain Landlord's Consent
to Subleases dated as of January 23, 1996 between Landlord and James River (the
"Consent") and (b) roof inspections to the extent contemplated in Paragraph 7
below) of the Subleased Premises, as well as causing compliance with Section 4
of the Subleases.

     3.  To the extent any compliance with Section 4 of the Subleases relates to
liabilities or obligations which James River has retained under the JR Capital
Contribution Agreement ("Retained Liabilities"), James River shall indemnify
WinCup L.P. as provided in the JR Capital Contribution Agreement.  Additionally,
James River shall bear any costs and expenses incurred by James River in
conducting any inspections of the Subleased Premises, to the extent any such
actions are taken upon James River's initiative or in response to an inspection
undertaken by Landlord or its agents for the sole purpose of investigating
Retained Liabilities.
<PAGE>
 
     4.  If WinCup L.P. fails to vacate any of the Subleased Premises (as
defined in the Subleases) on the Expiration Date (as defined in the Subleases),
the Sublease governing such Subleased Premises shall continue on a month-to-
month basis upon the terms and conditions set forth in the Holding Over
provision of the governing Prime Lease, provided, however, WinCup L.P. shall be
liable for any loss, cost, damage or expense payable by James River to Landlord
as a result of such holding over.

     5.  James River agrees to pay to Landlord late charges paid pursuant to
paragraph 5 of the Consent; provided, however, that such late charges result
from James River's failure timely to turn over to Landlord amounts paid timely
by WinCup L.P. to James River for the benefit of Landlord.  WinCup L.P. agrees
that any rent payments or other amounts due to Landlord made to James River for
the benefit of Landlord shall be delivered to James River so as to be received
by it at least one (1) business day prior to the date such amounts are due to
Landlord.

     6.  Pursuant to paragraph 7 of the Consent, at the expiration of the
Subleases, James River shall take all actions required by Landlord with respect
to unauthorized alterations on the roof of the factory building, but only to the
extent such alterations are the result of James River's conduct prior to the
Closing Date (as defined in the JR Contribution Agreement).

         In the event the foregoing is acceptable to you, kindly indicate your
agreement by signing and dating both copies of this side letter agreement in the
spaces provided and return one fully executed copy to James River for its files.

                    ---------------------
Agreement at any time for Cause (as hereinafter defined) upon written notice to
Executive, effective upon the date of such written notice. "Cause" shall be
defined as (a) conviction of the Executive for a felony or misdemeanor involving
dishonesty, fraud or moral turpitude under the laws of the United States or any
state thereof or other jurisdiction in which Executive performs services; (b)
breach of Section 9 hereof; or (c) removal of WinCup as General Partner of
Employer pursuant to Section 8.4 of that certain Limited Partnership Agreement,
dated as of the date hereof, between WinCup and James River. In the event of
termination for Cause, the Employer shall have no further obligations or
liabilities to Executive hereunder, except that Executive shall be entitled to
receive any accrued but unpaid Salary and expense reimbursement, and to retain
all other amounts received by Executive pursuant to this Agreement prior to such
termination for Cause.

          8.   Non-Disclosure of Trade Secrets and Other Information.
               ----------------------------------------------------- 

          Executive agrees that he will not, during the Term of this Agreement

writing.  It is understood that this applies to information of

                                      -6-
<PAGE>
 
either a technical or commercial nature, including secret processes, formulas,
machinery, utensils, manufacturing techniques and arts, customer lists, market
information and the like.  The terms 'secret' and 'confidential' shall include
all unpublished information and all information and data known to some but not
to all members of the trade or industry to whom such information or data would
be in any manner useful.

          All memoranda, notes, records, or other documents made or compiled by
Executive, or made available to Executive while employed by Employer, are
Employer's property and all copies thereof shall be delivered to Employer on
termination of Executive's employment or at any other time upon the request of
Employer.

          9.  Restrictive Covenant.
              -------------------- 
                                         
              (a)  Non-Competition. 
                   ---------------  
                   Executive agrees that, so long as he is employed by Employer
pursuant to this Agreement and for a period of five (5) years thereafter, he
will not, directly or indirectly, as a sole proprietor, member of a partnership,
stockholder, investor, officer or director of a corporation, or as an employee,
agent, associate or consultant of any person, partnership or corporation other
than Employer or in any other capacity:

                   (i)  own, manage, operate, participate in, perform
services for or otherwise carry on a business which sells or manufactures one-
piece foam cups within the United States or

                                      -7-
<PAGE>
 
Canada (the "Territory"); provided that ownership of not more than five percent
(5%) of the issued and outstanding shares of a class of securities of a
corporation the securities of which are traded on a national security exchange
or in the over-the-counter market shall not be deemed ownership of the issuer of
such shares for the purposes of this section;

                   (ii)   induce or attempt to persuade any employee of
Employer or any of its affiliates to terminate such employment relationship in
order to enter into any such relationship with such person or to enter into any
such relationship on behalf of any other business organization which sells or
manufactures one-piece foam cups in the Territory;

                   (iii)  solicit any business related to the manufacture or
sale of one-piece foam cups in the Territory from any clients, customers, or
prospective or former clients or customers of Employer or its affiliates; or

                   (iv)   perform services of any nature for any entity
which manufactures or sells one-piece foam cups in the Territory.

               (b) Injunctive Relief. Without limiting the right of Employer or
                   -----------------
any of its successors or permitted assigns to pursue all other legal and
equitable rights available to them for violation of the covenants set forth in
subparagraph 9(a) hereof, it is agreed that such other remedies cannot fully
compensate Employer and its successors and assigns for such a violation and

                                      -8-
<PAGE>
 
that Employer and its successors and assigns shall be entitled to injunctive
relief to prevent violation or continuing violation hereof.  It is the intent
and understanding of each party hereto that if, in any action before any court
or agency legally empowered to enforce this covenant, any term, restriction,
covenant or promise is found to be unreasonable and for that reason
unenforceable, then such term, restriction, covenant or promise shall be deemed
modified to the extent necessary to make it enforceable by such a court or
agency.

          10.  Arbitration.
               ----------- 

               Except as provided in subparagraph 9(b) hereof, any controversy
or claim arising out of or relating to this Agreement or the breach thereof
shall be settled by arbitration in Wilmington, Delaware, in accordance with the
rules of the American Arbitration Association and any decision made in
accordance with such rules shall be binding on all parties in interest, and
judgment upon any award rendered may be entered in any court having jurisdiction
thereof.

          11.  Waiver of Breach.
               ---------------- 

               The waiver by Employer or Executive, as the case may be, of a
breach of any provision of this Agreement by Executive or Employer, as the case
may be, will not operate or be construed as a waiver of any subsequent breach by
Executive or Employer, as the case may be.

          12.  Entire Agreement.
               ---------------- 

               This instrument contains the entire Agreement of

                                      -9-

               FIRST AMENDMENT TO EXECUTIVE EMPLOYMENT AGREEMENT
               -------------------------------------------------

     THIS FIRST AMENDMENT TO EXECUTIVE EMPLOYMENT AGREEMENT ("Amendment") is
made as of October __, 1995 between BENCHMARK CORPORATION OF DELAWARE, a
Delaware corporation (the "Company") and RICHARD HUNSINGER (the "Executive").

                              W I T N E S S E T H:

WHEREAS, the Company and Executive are parties to a certain Executive Employment
Agreement, dated as of May 1, 1993 (as amended and/or modified, the
"Agreement");

WHEREAS, the Executive desires to continue his employment by the Company and the
Company desires to continue the employment of the Executive; and

WHEREAS, the Company and the Executive desire to amend the Agreement as more
particularly set forth herein.

NOW THEREFORE, in consideration of the mutual promises and covenants contained
herein, and intending to be legally bound hereby, the parties hereto agree as
follows:

1.   Amendments.
     ---------- 

     (a) The first sentence of Section 1.1 of the Agreement is hereby amended
and restated to read in its entirety as follows:

         1.1 Position and Duties. During the term of this Agreement, the
             ------------------- 
         Executive shall serve on a full-time basis as Senior Vice President of
         Sales and Marketing of the Company, with such powers and
         responsibilities as are customarily incident to such office.

     (b) The first sentence of Section 1.3(a) of the Agreement is hereby amended
and restated to read in its entirety as follows:

         (a) Subject to the termination provisions of Article II hereof, the
         initial term of this Agreement shall begin on May 1, 1993 and shall
         expire on November 6, 2000.

     (c) Section 1.4(a) of the Agreement is hereby amended and restated to read
in its entirety as follows:

         (a) Salary. During the term of this Agreement, the Company shall pay to
             ------   
         the Executive a base salary (the "Base Salary") at the rate of not less
         than $145,000
<PAGE>
 
         per annum, which shall be subject to increase as provided in the
         following sentence. Every twelve months, the Base Salary shall be
         reviewed and increased by an amount equal to the product obtained by
         multiplying $145,000 by the percentage change in the CPI-U from the
         first full calendar month of the first year of the term to the first
         full calendar month of the subject year of the term. As used herein
         "CPI-U" shall mean "Consumer Price Index -- Seasonally Adjusted U.S.
         City Average For All Items For All Urban Consumers (1982-84 = 100),"
         published monthly in the "Monthly Labor Review" of the Bureau of Labor
         Statistics of the United States Department of Labor. If the base year
         "(1982-84 = 100)" or other base year used in computing the CPI-U is
         changed, the figures used in making the adjustment shall be changed
         accordingly, so that all increases in the CPI-U are taken into account
         notwithstanding any such change in the base year. In no event shall the
         percentage increase in the Base Salary for any year of the term be less
         than three and one-half percent (3.5%) of the Base Salary for the
         previous year. The Base Salary shall be payable in semi-monthly
         installments.

     (d) Section 1.4(c)(ii) of the Agreement is hereby amended and restated in
its entirety as follows:

         (ii) During the term of the Agreement, the Company shall provide the
         Executive with an automobile at the Company's expense.

     (e) A new sentence is hereby added to Section 1.5 of the Agreement to read
in its entirety as follows:

         The Company shall, at its sole cost and expense, provide the Executive
         with satisfactory legal counsel to defend any action, suit or
         proceeding commenced against Executive during the term of this
         Agreement with respect to any antitrust matters related to Executive's
         employment with the Company.

     (f) Section 2.3 of the Agreement is hereby amended to delete paragraphs (b)
and (e) thereof and the remaining paragraphs of Section 2.3 of the Agreement are
hereby renumbered accordingly.

2.   Ratification and Confirmation.  The terms and conditions of the Agreement,
     -----------------------------                                             
as amended by this Amendment, are hereby ratified and confirmed and shall
continue in full force and effect.

3.   Miscellaneous. This Amendment shall have effect as of this date.  This
     -------------                                                         
Amendment may be executed in two or more

counterparts, and by different parties on different counterparts, each of which
shall be deemed an original and in making proof of this Amendment it shall be
necessary only to produce sufficient counterparts.  This Amendment and the
rights and obligations of the parties hereunder shall be construed in accordance
with and shall be governed by the laws of the Commonwealth of Pennsylvania.

     IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of

of this Agreement, the Executive shall not, without the prior written consent of
the Company, engage directly or indirectly in any business (either financially 
or as a shareholder, employee, officer, partner, independent contractor or 
owner, or in any other capacity calling for the rendition of personal services 
or acts of management, operation or control)

                                     - 6 -

which is competitive with the business of the Company in any geographical area 
in which such entity engages in business.  Furthermore, the Executive agrees 
that for so long as this Agreement is in effect and for a period of two (2) 
years following the termination of this Agreement for any reason whatsoever, the
Executive shall not hire, as employee, consultant, agent or otherwise, nor shall
he solicit the participation in any business activity that is competitive with 
the business of the Company (as owner, part-owner, shareholder, partner, 
director, officer, trustee, employee, agent or consultant or in any other 
capacity) of any person who is an employee, consultant or agent of the Company, 
or who was such an employee, consultant or agent within one year preceding the
date of the termination of the Executive's employment with the Company.

       3.2  Non-Disclosure.  The Executive recognizes and acknowledges that he 
            --------------
will have access to certain confidential information of the Company and that 
such information constitutes valuable, special and unique property of the 
Company.  The Executive agrees that he will not, for any reason or purpose 
whatsoever, during or after the term of this Agreement, disclose any of such 
confidential information to any party without the express authorization of the 
Company except as necessary in the ordinary course of performing his duties 
hereunder.  The Executive acknowledges and agrees that all papers, documents, 
writings and other materials produced by him or coming into his

                                     - 7 -

possession during his employment hereunder will at all times remain the property
of the Company and upon termination of this Agreement the Executive shall 
surrender all such materials to the Company.

     3.3   Injunctive Relief; Consideration for Enforcement.
           ------------------------------------------------
           The Executive acknowledges that his compliance with the agreements in
Sections 3.1 and 3.2 hereof is necessary to protect the goodwill and other 
proprietary interests of the Company and that during the performance of his 
duties under this Agreement he will become conversant with the affairs, trade 
secrets, customers and other proprietary information of the Company. The 
Executive acknowledges that a breach of his agreement in Sections 3.1 and 3.2 
hereof will result in irreparable and continuing damage to the Company for which
there will be no adequate remedy at law; and the Executive agrees that in the 
event of any breach of the aforesaid agreements, the Company and its successors 
and assigns shall be entitled to injunctive relief and to such other and further
relief as may be proper; provided, however, that the Company shall not be
entitled to enforce the Executive's agreements in Section 3.1 hereof unless the
Company shall first notify the Executive in writing of its intention to do so
and, in consideration for the obligations of the Executive not to compete as
provided in Section 3.1 hereof, the Company shall pay the Executive his Base
Salary in accordance with the terms of Section 1.4(a) hereof for the period
during which the Company elects to enforce the Executive's
                                     - 8 -
<PAGE>
 
compliance with Section 3.1, which period shall not exceed two (2) years 
immediately following the termination of the Agreement. If the Company 
materially fails to comply with the payment obligation required by the

outstanding principal hereunder at an annual rate of ten percent (10%) for the
first two (2) years and twelve percent (12%) thereafter.  For the first two (2)
years, accrued interest shall be compounded quarterly and added to the principal
on the first day of each July, October, January and April. Thereafter, but only
to the extent that (i) all sums due and owing under that certain Senior
Promissory Note, dated the date hereof, issued by Maker in favor of Payee, in
the original principal amount of Seven Million Dollars ($7,000,000) (the "JR
$7,000,000 Note") shall have been satisfied in full; (ii) all sums due and owing

satisfied in full; and (v) all sums due and owing under that certain

the month after all sums due and owing under the JR $7,000,000 Note, the WinCup
$1,800,000 Note, the JR $4,400,000 Note, the Scott $300,000 Note, the JR

the Payee in the amount of Four Hundred Fifteen Thousand Six Hundred Twenty-Five
Dollars ($415,625) each, with a final payment on the fifth anniversary hereof in
an amount equal to the remaining unpaid principal balance and all accrued
interest thereon; provided, however, to the extent there are insufficient funds
available to pay in full any scheduled principal payment due hereunder (other
than the final payment) and the principal payment due on the same date under the
Scott $2,700,000 Note, such scheduled principal payment due hereunder shall be
ratably reduced to an amount equal to (1) the ratio of (a) the scheduled
principal payment due hereunder relative to (b) the aggregate of the scheduled
principal payment due hereunder plus the scheduled principal payment due under
the Scott $2,700,000 Note, multiplied by (2) the funds available to make such
principal payment. Subject to the terms of the Subordination Agreements (as
hereinafter defined), this Note may be prepaid at any time without penalty or
prepayment charge.

                         Calculation of Purchase Price

     An example of the Purchase Price for a Closing occurring after December 31,
1996 would be as follows:

     1.  Closing Date -- July 15, 1997
 
     2.  Applicable Call Exercise Price -- $17,737,500 (Call Date = 
         June 30, 1997)
 
     3.  Calculation of applicable Per Diem Increment:
 
          a.  $18,356,250 - $17,737,500 = $618,750 (September 30, 1997 Call 
              Exercise Price less June 30, 1997 Call Exercise Price)
 
          b.  Per Diem Increment:  $618,750 / 90 days = $6,875
 
          c.  Number of days between Closing Date (July 15, 1997) and Date of  
              Applicable Call Exercise Price (June 30, 1997) = 15
 
          d.  $6,875 X 15 days = $103,125
 
     4.   Aggregate Purchase Price for July 15, 1996 Closing = $18,140,625
          ($17,737,500 + $300,000 + $103,125)

c/o Radnor Holdings Corporation

Radnor, PA  19087
Attention:  Michael T. Kennedy, Chairman

Dear Mr. Kennedy:

     Notwithstanding any language to the contrary in those certain Sublease
Agreements (collectively, the "Subleases"), each dated as of January 20, 1996,
and entered into between James River Paper Company, Inc. ("James River"), and
WinCup Holdings, L.P. ("WinCup L.P."), with respect to the premises located
generally in Corte Madera, California, or any of the Prime Leases referred to
therein, leased from Hunt Brothers Leasing, L.L.C. ("Landlord"), the
undersigned, intending to be legally bound hereby, agrees as follows:

     1.   Notwithstanding any provision to the contrary in the Subleases, WinCup
L.P. shall not be deemed to have assumed, and does not assume, any liabilities
for matters disclosed by any inspections of the Subleased Premises other than as
set forth in (a) Paragraph 2 below and (b) Section 1.3(a) of that certain JR
Capital Contribution Agreement, dated as of January 20, 1996, between WinCup
L.P. and James River (the "JR Contribution Agreement").

     2.   WinCup L.P. shall be required to reimburse James River, within thirty
(30) days of receipt of invoice from James River, for amounts required to be
paid by James River to Landlord (as defined in the Subleases) for costs and
expenses incurred by Landlord in conducting inspections (other than 
(a) environmental inspections relating to "Retained Liabilities", as hereinafter
defined, and as contemplated in Paragraph 8 of that certain Landlord's Consent
to Subleases dated as of January 23, 1996 between Landlord and James River (the
"Consent") and (b) roof inspections to the extent contemplated in Paragraph 7
below) of the Subleased Premises, as well as causing compliance with Section 4
of the Subleases.

     3.   To the extent any compliance with Section 4 of the Subleases relates
to liabilities or obligations which James River has retained under the JR
Capital Contribution Agreement ("Retained Liabilities"), James River shall
indemnify WinCup L.P. as provided in the JR Capital Contribution Agreement.
Additionally, James River shall bear any costs and expenses incurred by James
River in conducting any inspections of the Subleased Premises, to the extent any
such actions are taken upon James River's initiative or in response to an
inspection undertaken by Landlord or its agents for the sole purpose of
investigating Retained Liabilities.
<PAGE>
 
     4.   If WinCup L.P. fails to vacate any of the Subleased Premises (as
defined in the Subleases) on the Expiration Date (as defined in the Subleases),
the Sublease governing such Subleased Premises shall continue on a month-to-
month basis upon the terms and conditions set forth in the Holding Over
provision of the governing Prime Lease, provided, however, WinCup L.P. shall be
liable for any loss, cost, damage or expense payable by James River to Landlord
as a result of such holding over.

     5.   James River agrees to pay to Landlord late charges paid pursuant to
paragraph 5 of the Consent; provided, however, that such late charges result
from James River's failure timely to turn over to Landlord amounts paid timely
by WinCup L.P. to James River for the benefit of Landlord.  WinCup L.P. agrees
that any rent payments or other amounts due to Landlord made to James River for
the benefit of Landlord shall be delivered to James River so as to be received
by it at least one (1) business day prior to the date such amounts are due to
Landlord.

     6.   Pursuant to paragraph 7 of the Consent, at the expiration of the
Subleases, James River shall take all actions required by Landlord with respect
to unauthorized alterations on the roof of the factory building, but only to the
extent such alterations are the result of James River's conduct prior to the
Closing Date (as defined in the JR Contribution Agreement).

          In the event the foregoing is acceptable to you, kindly indicate your
agreement by signing and dating both copies of this side letter agreement in the
spaces provided and return one fully executed copy to James River for its files.

                               EXHIBIT VII(5)(B)

                        LANDLORD'S CONSENT TO SUBLEASES


     THIS AGREEMENT IS MADE as of the 23rd day of January, 1996, between JAMES
RIVER PAPER CO., INC., a Virginia corporation ("Tenant") and HUNT BROTHERS
LEASING, L.L.C., successor in interest to HUNT BROTHERS LEASING, a partnership
("Landlord").

     WHEREAS, Tenant is entering into a joint venture with WinCup Holdings,
L.P., a Delaware limited partnership; and

     WHEREAS, in connection therewith, it is necessary for Tenant to enter into
certain subleasing transactions, which require Landlord's consent, all as more
hereinafter described and set forth; and

     WHEREAS, Landlord is willing to consent to Tenant's entering to said
subleases, but only upon the terms and conditions hereinafter set forth.

     NOW, THEREFORE, for good and valuable consideration, the receipt of which
is hereby acknowledged, Landlord and Tenant hereby agree as follows:

     1.   Consent to Subleasing.  In connection with that certain Office
          ---------------------                                         
Building Lease, Plant Lease, Warehouse Lease, and Engineering Lease
(collectively, the "Leases"), all dated November 8, 1989, as subsequently
amended and pertaining to premises commonly known as 240 Tamal Vista Boulevard,
195 Tamal Vista Boulevard, 205 Tamal Vista Boulevard, and 201 Tamal Vista
Boulevard, respectively, all located in Corte Madera, California, Landlord
hereby consents to Tenant's subleasing the premises to WinCup Holdings, L.P., a
Delaware limited partnership, pursuant to the terms and conditions to those
certain Sublease Agreements dated January 20, 1996, copies of which are attached
hereto as Exhibit A and incorporated herein for all purposes.

     2.   No Changes to Leases.  Notwithstanding Landlord's consent to the
          --------------------                                            
hereinabove described subleasing transactions, except as hereinafter
specifically set forth, all of the rights and/or obligations of Landlord and
Tenant under the Leases shall remain unamended and in full and effect and
Landlord's consent to the subleasing described herein shall not constitute
consent to any subsequent assignment or subleasing without Landlord's prior
written consent and approval.

     3.   Insurance Throughout the Term of the Sublease.  All insurance
          ---------------------------------------------                
currently provided by Tenant shall continue to be provided by Tenant throughout
the term of the subleases (with the same quality of provider and scope of
coverage).  Landlord shall be provided with at least thirty (30) days' written
notice prior to the change of any insurance currently in effect.

                                       40
<PAGE>
 
     4.   Security Deposit.  Upon Tenant's execution hereof, Tenant shall
          ----------------                                               
deposit with Landlord a sum equal to one (1) month's current rent under the
Leases as security for Tenant's and Subtenant's faithful performance of their
obligations under the Leases.  Landlord and  Tenant agree that the security
deposit may be commingled with funds of Landlord and Landlord shall have no
obligation or liability for payment of interest on such deposit.  Tenant shall
not mortgage, assign, transfer, or encumber the security deposit and any attempt
by Tenant to do so shall be void, without force or effect and shall not be
binding upon Landlord.

     If Tenant fails to pay any amount when due and payable under the Leases, or
fails to perform any of the terms and conditions of the Leases or the additional
terms and conditions as set forth herein, Landlord may appropriate and apply or
use all or any portion of the security deposit to cure the default, and Landlord
may so apply or use the deposit without prejudice to any other remedy Landlord
may have on account of Tenant's default or breach.  If Landlord so uses any of
the security deposit, Tenant shall, within ten (10) days after written demand
therefor, restore the security deposit to the full amount originally deposited;
Tenant's failure to do so shall constitute an act of default under the Leases.
Within fifteen (15) days after the term of the Leases has expired and Tenant has
vacated the Premises, provided Tenant is not then in default on any of its
obligations thereunder, Landlord shall return the security deposit to Tenant.

     5.   Late Charge.  If Tenant shall fail to pay within ten (10) days from
          -----------                                                        
when due and payable any rent or other amounts or charges which Tenant is
obligated to pay under the Leases, Tenant shall pay a late charge equal to ten
percent (10%) of such amount that is due.  Tenant acknowledges that any late
payments will cause Landlord to incur costs and expenses not contemplated under
the Leases, including, but not limited to, administrative and collection costs
in processing any accounting expenses, the exact amount of which is extremely
difficult to fix.  Therefore, Tenant agrees that the late charge described
herein represents a reasonable estimate of such costs and expenses and is fair
compensation to Landlord for the loss suffered by such non-timely payment.
Acceptance of any late charge will not constitute a waiver of Tenant's default
with respect to such non-payment by Tenant or prevent Landlord from exercising
any rights or remedies available to Landlord under the Leases.

     6.   Pending Environmental Matters.  On or before June 1, 1996, Tenant
          -----------------------------                                    
shall obtain final governmental closure both for the storm drain and the
underground storage tank, as described in Patrick McHugh's letter to John Jang
of the California Regional Quality Control Board dated October 16, 1995.  Any
storm drain work associated therewith shall be completed by Tenant at its sole
cost and expense on or before February 1, 1997.  Copies of any correspondence
sent or received by Tenant or subtenant in connection with the matters described
in this paragraph shall be immediately delivered to Landlord.


                                       2

<PAGE>
 
     7.   Unauthorized Alterations.  Tenant acknowledges that it has made
          ------------------------                                       
numerous alterations, including the installation of pollution equipment, on the
roof of the factory building, without Landlord's knowledge or prior approval as
was required by the Leases.  Landlord shall assess all such work at the
expiration of the Leases, and Tenant shall take such measures as Landlord may
request, to remove said alterations and/or correct any damage occasioned
thereby.

     8.   Environmental Inspection.  As set forth in the subleases, Landlord
          ------------------------                                          
shall have the right to have environmental inspections performed upon the
Premises.  The costs of such inspections shall be paid for by Tenant and any
work recommended thereunder shall be performed in a prompt and timely manner, as
an obligation of Tenant at Tenant's sole cost and expense.

     9.   Financial Statements.  Tenant shall provide Landlord with Subtenant's
          --------------------                                                 
quarterly financial statements throughout the term of the subleases.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first set forth above.

                            -----------------------
                           RECORDS MANAGEMENT POLICY
                           -------------------------


                 RECORDS CREATION, RETENTION AND DISTRIBUTION
                 --------------------------------------------

    PURPOSE: To establish a uniform James River policy for creating,
distributing, retrieving, preserving, protecting, storing and disposing of
company records.

    SCOPE:  The policy enunciated in this Policy Statement is applicable to
corporate headquarters and all business groups, plants and offices in the United
States, and it should apply to all James River records, whether maintained in
central files, offices or homes, regardless of form (e.g., hard copy, microfilm
                                                     ----
or electronic format).


    POLICY GOAL:  To eliminate the cost of unnecessary records.

    POLICY APPROACH: Only records expressly and regularly required by
business needs or legal obligations shall be maintained, and then only for the
periods of time actually required. All other records shall be discarded
immediately after use.

    POLICY COMPONENTS:  This purpose will be accomplished by:

    A.  Limiting the records created within James River to those necessary
for James River's ongoing business;

    B.  Encouraging James River personnel to strive for accuracy and brevity
in writings;

    C.  Limiting the circulation of documents to people who genuinely need
the information;

    D.  Encouraging the immediate disposal of routine, irrelevant or
marginally useful documents;

    E.  Discouraging the creation and retention of large numbers of personal
files;

    F.  Maintaining truly important records in accessible central files or
        organized records storage areas; and

    G.  Establishing and following timetables for the timely disposal of all
records.

                                 BACKGROUND
                                 ----------

    Modern businesses generate and retain large volumes of records with
inadequate thought to their clarity or ultimate usefulness. Frequently these
records are distributed to people who cannot practically use the information.

    The cost of such practices, including reading, filing and storing
originals and multiple copies, is enormous.

    Further complications arise because records often outlast the
recollections of their authors or recipients. Poorly worded documents require
expensive research to clarify ambiguities, and the outcome of lawsuits sometimes
hinges on uncertainties caused by innocent but unclear writings.

    These costs and risks are best addressed by a records management program
which establishes guidelines for the creation and circulation of documents,
encourages quick disposal of routine and marginally relevant records and
provides for careful organization and retention of truly important records in
central, readily available files. It is the purpose of this policy to create,
implement and maintain such a program.

                                     VI-3
<PAGE>
 
                                   OVERVIEW
                                   --------

1.  RECORD CREATION AND CIRCULATION

    A.  Purpose
        -------
    The legitimate purposes of any record, whether in paper or electronic
format, are to communicate facts or positions or maintain a record of facts or
positions.

    Written documents and other records are expensive to create and maintain.

    Where the purpose of a document is to communicate, you should first ask
whether you can use less expensive methods, such as telephone or face-to-face
meetings. 

    Where the purpose is to preserve factual understandings or positions,
consider whether that purpose justifies a writing.

    Create written records only when necessary.

    B.  Methods
        -------

    When a written record does become necessary, you must understand that your
writing may remain in some file long after it has served its usefulness, and it
may be read by someone with no knowledge of the immediate circumstances.  To
avoid later misreadings of your intentions, do not impute bad motives to others,
overstate a position, exaggerate dangers or otherwise write in a way that would
mislead a later reader (in-jokes, posturing, and cryptic messages are best left
to voice communications, if at all).

    When writing, focus on the facts or company position required to be
                               -----    ----------------
communicated or preserved. Strive for accuracy and clarity. Whenever possible,
recheck factual statements for accuracy or qualify as necessary.

    Clear writing also demands that you reread your work to ensure that it is
clear of ambiguities and possible misunderstandings.

    C.  Circulation
        -----------

    Circulate your writings only to people who have a genuine need to know the
facts or positions stated. Addressees should not further distribute documents
unless the 

                                     VI-4
<PAGE>
 
potential recipient meets the test of the original addressee, i.e., a person
with a genuine need to know the facts or positions stated.

2.  RECORD RETENTION

    A.  Purpose
        -------

    The purpose of a Records Management Program is to effect an orderly
transition of records from creation to disposal. The goal is to create only
necessary records and keep those records only as required for operations or
legal compliance. Because a record might be useful at some unspecified future
                                   -----
time does not, when multiplied by a million records created each year within
James River, justify keeping it.

    When a record is not legally required to be kept and there is serious doubt
about a record's future usefulness, discard or recycle it.

    B.  Methods
        -------

    This Program addresses the specific problems and policies applicable to
different functional categories within James River and the records typically
handled within those functions.  This Program establishes retention practices
applicable to each record category, regardless of the form in which it is
maintained (e.g., hard copy, computer tape, disk or hard drive, microfiche or
            ----
film, laser disk or by means of any other technology).

    Consistent adherence to these practices is a major step toward properly
managing James River's records.

    C.  Retention Times
        ---------------

    Each functional category addresses specific record categories and assigns a
retention period to each.

    Any period stated in years (e.g., "3 years") refers to fiscal years. Thus, a
                                ----
record with a three year period created during 1991 should be discarded for
recycling at the end of the third full fiscal year after its creation (e.g.,
                                                                       ----
December 31, 1994).

    "Current", "discard after completion" and similar terms mean that there are
no legal retention requirements and that the record should be discarded when it
is no longer being actively used, unless there are unresolved issues, such as
dissatisfaction on the part of the customer, supplier or James River that may
lead to legal claims.

    D.  Decision Making
        ---------------

    1)  Author

        The author should normally determine whether a record should be
    retained, unless it was created at someone else's express directions, in
    which case that person must determine whether (and where) to retain that
    record.

    2)  Recipients of James River Records

        Recipients of James River records (unless created at the recipient's
    request) should assume that the author will take responsibility for
    retaining the record.

    3)  Recipients of Non-James River Records

        The addressee or first recipient of a record from outside of James River
    should determine whether (and, if so, where) to retain the record.

        Since this category would include "junk mail" and large quantities of
    routine correspondence without any lasting importance, much can be disposed
    of after reading. Discretion must be used, and no document legally required
    to be kept (see below) or which states a legal or factual position likely to
    be contradictory to or confirmatory of a James River position or
    understanding should be summarily discarded, i..e., documents that might be
    received from a supplier, customer or contractor relating to prices, quality
    or other contract or warranty claims.


E.  Government Inquiries and Investigations; Litigation
    ---------------------------------------------------

    Any document which comes from a court or governmental agency must be treated
as one required to be kept. Unless the document is a type which is routinely
received and handled within a location (such as garnishments or subpoenaes for
an employee's earnings), a copy should be immediately forwarded to the James
River Legal Department, outside lawyers already working on the matter, or a
James River task force or group already working on the matter (e.g., tax
                                                               ----
returns, confirmations of environmental filings, etc.).

                                     VI-6
<PAGE>
 
    When James River receives notice of any legal matter, including a subpoena
                                        ---
of James River files, lawsuit, government investigation, a government charge or
threatened action, immediately use the Records Retention Suspension Notice form
to suspend routine disposal of documents relating to that matter, notify the
Legal Department immediately and follow the attorneys' specific recommendations
regarding the management of the affected records.

    F.  Confidentiality
        ---------------

    Every author, recipient or record custodian must consider the sensitive
nature of the documents in his possession and act accordingly. For example,
highly confidential, proprietary records may require limited access storage and
secure disposal. The law will usually grant no greater protection to a company's
records than the company itself takes, and some courts have held that records
left in public areas or discarded intact in trash are not legally protected.

    G.  Drafts
        ------
    Except in rare cases, such as contract negotiations, drafts should not be
retained.  The final version alone has operative force, and no purpose is served
by keeping drafts.

    H.  Copies
        ------

    Copies should be made sparingly and seldom retained. If the author fulfills
his responsibility of filing the original in a central file, it will be
available as necessary. Accordingly, retain copies only in special situations,
such as retaining a copy as a format sample or guide, for ready reference on an
active matter (see 3[C]) or when two locations must have ready reference.
               ---

    Except in these special circumstances, the recipient or holder of a copy
should read and discard.

3.  RECORD LOCATION

    A.  Central Files
        -------------

                                     VI-7
<PAGE>
 
    The most efficient filing systems use central files in locations accessible
to all who need the information. On occasions, there may be a temporary need for
a desk or personal file, such as when a specific matter is receiving a high
level of attention, but as soon as the matter is resolved or becomes routine,
documents required to be kept should be merged into the central file and
duplicates and other unnecessary documents discarded for recycling.

    B.  Personal Files
        --------------

    In one sense, there are no "personal" files relating to James River's
business. Even files kept in employees' homes may be considered company files
that must be produced to government investigators and courts.

    Moreover, personal files usually duplicate central files and increase
difficulty and cost of locating all relevant files.

    Accordingly, no file relating to James River's business should be considered
personal, and desk or "personal" files should be created only when necessary and
merged with the central files when the immediate need has ended (see 3[A]).
                                                                 ---

    C.  Computer Files and Purchased Software
        -------------------------------------

    Information stored or produced on personal computers are "records" covered
by the Records Management Program. When the records have been downloaded to
floppy disks or long-term storage medium, the medium itself should be either
discarded or reformatted at the end of the applicable retention period. When
records have been retained on hard drives, they should be erased or reformatted
as appropriate unless more specific instructions are subsequently issued.

    The Records Management Committee will issue specific instructions applicable
to records maintained on central computers or in central long-term storage.

    Purchased Software Packages contain a License Agreement specifying the terms
and conditions in which you must comply in order to legally use the product. In
regard to product upgrades, upon receipt of a new release of the software, all
prior releases should be destroyed within 90 days.

                                     VI-8
<PAGE>
 
    D.  Duplicate Files
        ---------------

    Rarely is it necessary to have full duplicate files unless one is a backup
while the primary file is unavailable (for example, during tax audits). It may,
however, be necessary for different files to contain some duplication. This
should not be done thoughtlessly, but especially with financial and personnel
matters and information required by government regulations, it may occasionally
be more efficient to have some duplication. (Adherence to the retention periods
will help reduce the volume and search time.)

4.  OTHER MATTERS

    A.  Exemptions
        ----------

    Where there is a genuine need to retain documents beyond the retention
period, an exemption may be granted by the James River Records Management
Committee. Requests must be made on the appropriate form. The exemption, if
granted, will be in writing and must be attached to the applicable records. If
the exemption establishes a revised retention date, it must be followed.

    B.  Contractual Requirements
        ------------------------

    Bond and trust agreements and documents related to mergers, asset sales and
acquisitions occasionally impose special record-keeping requirements.

    In order for James River to apply this Program without compromising its
contractual undertakings, anyone aware of current contractual commitments or who
has responsibility for such contractual undertakings in the future must
immediately notify the Records Management Committee and include copies of the
pertinent contractual provisions.

    The Committee will provide guidance and, where necessary, the appropriate
written exemption from the Program.

    C.  Record Types Not Addressed
        --------------------------

    Because of the pervasive nature of government regulations, some locations
may generate highly specialized documents subject to national, state or even
local government retention requirements, which are not addressed by this
Program.

                                     VI-9
<PAGE>
 
    If you are aware of laws or regulations applicable to any James River
operations and which impose special retention requirements not addressed in this
Program, notify the Records Management Committee at once and include a copy or
reference to the law or regulation (if possible). The Committee will promptly
address your request and, if necessary, amend the Program.

                                     VI-10
<PAGE>
 
                           CONTRACTS AND AGREEMENTS
                           ------------------------


1.  SCOPE

    As used in the James River Records Management Program, "contracts" and
"agreements" are used interchangeably to describe legal arrangements between
James River and other parties for the sale, lease or exchange of goods or
services.  The arrangements may be identified as distributorship agreements,
broker contracts, supply agreements, leases, advertising contracts, consulting
agreements, license agreements, secrecy or confidentiality agreements, purchase
orders, sales orders, order acknowledgments, and confirmations, to name only a
few.

    Agreements and contracts include not only formal documents signed by all
parties, such as long-term supply agreements, but also informal writings that
confirm, reflect or contain terms of an oral contract or that explain, amend,
extend or terminate contracts.

    This section addresses the retention periods for all James River contracts
and agreements except for those related to the sale or leasing of real property
or timber (see "Leases, Deeds, Timber Purchases and Other Real Estate"),
individual non-compete, confidentiality, employment or consulting agreements
(see "Human Resources"), and routine sales of James River products (see "Sales
and Distribution").

2.  PURPOSE

    The purposes of this section are, first, to ensure that James River enters
into, amends and enforces such agreements consciously and carefully and, second,
to ensure that there exists a single file containing all documents reflecting
the formation, interpretation and administration of each James River contract.

3.  CONSIDERATIONS

    Since contracts create legal rights and obligations, James River must retain
all documents which contain contract terms, interpretations, and performance.

                                     VI-11
<PAGE>
 
    Due to the changing and sometimes informal nature of business relationships,
contracts may be made on the basis of a handshake, be modified by
correspondence, orders or "redi memos", and be changed if one party knowingly
allows the other to alter without challenge the nature or extent of performance
required by the express terms of the contract.

4.  MANDATORY RECORDS

    Except in the case of routine sales or specialized documents, such as real
estate transactions, every location or department actively involved in creating
or administering a contract should maintain a file for each contract which
contains all documents required to be kept.

    A.  Documents to Be Kept
        --------------------

        1)  Documents formally designated as legally binding (these are usually
negotiated by the parties and signed by each party's representatives);

        2)  Purchase orders, invoices, correspondence and similar documents
exchanged by James River and a vendor or customer which contain or reflect the
terms of a contract (for example, a letter suggesting a consulting relationship
and a purchase order would constitute a contract);

        3)  Documents exchanged between James River and a third party which
interpret a contract (this would include letters explaining the terms of earlier
documents or adding to or relaxing contract terms); and

        4)  Documents which reflect the other party's performance or
    nonperformance. (In this category, discretion is necessary. For example, if
    the contract is an elaborate construction agreement, detailed administrative
    records reflecting performance, including deadlines, changes, extras and the
    like, must be kept. If the contract is a distributor agreement, routine
    invoices and shipping records kept by the Financial Department need not be
    kept in the distributor file.)*

- ---------------------------------

    *Note: If the distributor (or customer) sends a purchase order, confirmation
or other writing that attempts to change the terms of the order or limitations
in James River's invoice, this writing could change the terms of sale. Such
documents must be 

                                     VI-12
<PAGE>
 
    B.  Retention Period
        ----------------

    All nonduplicative documents described above should be kept for six years
after the contract has been completed.

5.  DOCUMENTS TO BE RETAINED ONLY IN LIMITED CIRCUMSTANCES

    A.  Proposals That Do Not Ripen Into A Contract
        -------------------------------------------

    Routine preprinted or form proposals should be discarded so long as no
action has been taken to accept them.

    Proposals that grow out of discussions with vendors or customers may be
discarded if they do not ripen into a contract, provided all parties
                                                --------
acknowledged that there are no further obligations.  If the words or actions of
the other party suggest it believes that James River has either made an oral
agreement or has some continuing obligations related to the proposals, you
should retain the file intact and seek guidance from the James River Legal
Department.

    B.  Drafts
        ------

    The final document is the only one with legal authority.  Drafts exchanged
between parties are useful only as they reflect the intent or goal of one of the
parties, the meaning of a particular phrase or the additional terms, or if the
                                                                        --
contract fails to include language that the written contract is the final
agreement which supersedes all discussions and negotiations.  Only in these
cases should drafts or proposals received from the other parties be kept as
required by 4(A).  Drafts created by James River and only circulated internally
should be promptly discarded.



- --------------------------------------------------------------------------------
promptly and closely examined and, if appropriate, brought to the attention of
the James River Legal Department.

                                ENVIRONMENTAL
                                -------------


1.  SCOPE

    James River generates, collects and maintains numerous documents relating to
the possible impact of its operations on the physical environment, including
operations of environmental control equipment and production equipment and
disposal of manufacturing by-products. This Program is directed to those
functions and records.

2.  CONSIDERATIONS

    Federal and state government agencies have enacted numerous environmental
requirements which control manufacturing and disposal activities and impose
numerous record-keeping and reporting requirements.  These requirements are
strictly enforced.    

    There is an enforcement trend toward seeking criminal sanctions or severe
civil sanctions for alleged violations believed to be "willful" or "knowing",
and liability often depends on either repeated activities or documents which
seem to reveal an illegal corporate "state of mind". To maintain its position as
an environmentally sensitive company, James River will continue to emphasize
strict compliance with all laws and create and retain required environmental
records in accordance with this Program.

    This Program is not intended to identify every record required to be created
and maintained. Rather, the purpose of this Program is to identify those records
which have identifiable minimum retention periods or which James River should
maintain beyond minimum retention periods.

    The minimum retention periods expressed in this Program reflect primarily
federal considerations.  On occasions, state or local retention requirements may
exceed the retention periods stated for these records.  It is the responsibility
of each facility to determine state and local requirements and notify the
Records Management Committee of those requirements.

    While there are minimum legal retention times for certain documents, James
River should retain certain specific records indefinitely to address issues of
future liability or establish baselines for future permits or decisions.
Examples of records which should be kept indefinitely are those related to waste
disposal. Examples of

                                     VI-14
<PAGE>
 
records which should be kept longer than the statutory period are those that
serve as a baseline for pollution prevention measurements or for future permits.

1.   SCOPE

     James River generates, collects and maintains numerous financial records of
financial and related activities of the company.  Financial records, in addition
to recording all revenue and payment actions, are necessary to:

     A.   Ensure accurate recording of all transactions in accordance with
     generally accepted accounting principles, sound internal controls and
     proper business practices;

     B.  Allow the company to meet external reporting requirements;

     C.  Assist management in making business decisions based upon economic 
     facts;

     D.  Allow management to interpret business performance in light of business
     plans and controls; and

     E.  Minimize the company's tax burden through preparation of accurate tax
     returns and successful defense of audits.

     This section is directed to all activities relating to or supporting
financial activities except for specific categories such as "Contracts and
Agreements", "Sales and Distribution", and "Leases, Deeds and Other Real
Estate".

2.   CONSIDERATIONS

     The financial activities of the company are governed by numerous federal
and state agencies. They are also regulated by generally accepted accounting
principles and the Financial Accounting Standards Board (FASB), which
establishes rules regarding the recordation, presentation and disclosure of
financial events. The company also has expressed and implied fiduciary
responsibilities to control and protect the assets of the company and to
properly document all financial transactions.

     In order to comply with these laws and standards, James River will maintain
all financial and supporting documentation as required.

                                HUMAN RESOURCES
                                ---------------


1.   SCOPE

     The Human Resources Department generates and maintains personnel records
necessary to process employment actions and implement personnel procedures,
including hiring, promotions, layoffs, transfers, payroll transactions and
withholding obligations.  The Human Resources Department also manages and
administers James River's pension and welfare plans.  It is to persons involved
in these procedures and processes that this section is directed, whether they
are Human Resources or Industrial/Employee Relations personnel.

2.   CONSIDERATIONS

     Employment and labor matters are heavily regulated.  Federal, state and,
sometimes, local government agencies enforce a wide range of laws and
regulations affecting wages and hours, equal employment, employee organizational
activities, workplace health and safety, and employee benefits.  Many of these
regulations also impose record-keeping and reporting requirements.  (See
                                                                     ---
Appendix A.)  State common law may also create various contractual rights for
employees and provide remedies for such employment-related conduct as wrongful
discharge, defamation and infliction of emotional distress./1/

     Compliance within these many laws and regulations is often established
through records created or maintained by the Human Resources group. Thus,
thoughtful adherence to the following guidelines is essential.

     With few exceptions (noted below), government regulations do not dictate
the manner in which required information is to be organized and stored.
Similarly, James River has not created a single, organized records system for
each Human Resources office, and the current organizational arrangement at each
location reflects the history

- --------------------
     /1/Federal statutes and regulations are the primary sources of legal
requirements for the retention of employment-related records and are the focus
of these guidelines. State laws in this area tend to parallel corresponding
federal laws. If you are aware of state or local requirements that may be
different from those listed in this Program, immediately notify the Records
Management Committee using the Form on Page XIV-1.

                                     VI-27
<PAGE>
 
of that location, the make-up of the work force and the individual programs in
place (which may often be affected by the presence of one or more unions). This
Program, therefore, addresses Human Resources record keeping from a functional
point of view. It does assume, however, that each Human Resources office will
maintain separate files on each current and former employee ("personnel files")
which will contain a large amount of the required information. Timecards,
arbitration files, job postings, required reports and other matters of general
applicability are usually kept separate, but the form and arrangements of such
files may be determined by each office's needs. Records of EAP referrals,
medical records, and I-9s must be kept separately in files with limited
accessibility.

     Some general files will duplicate information in personnel files, and the
general rule against having more than one copy can be relaxed where it is
necessary to access information both by general categories and by employee name
or position.  Extensive use of multiple copies, however, makes it more difficult
to follow retention schedules and defeats a purpose of the Records Management
Program.

3.   MANDATORY RECORDS/2/

     The retention periods listed below are separated by the stage of employment
for ease of application. The use of these categories does not imply that a Human
Resources office must keep information in separate files by the particular
                 ----
heading (e.g., exit interviews).
         ----

                                                       Retention Periods
                                                       (years after close
                                                       of fiscal year)
                                                       ---------------

     A.  Pre-employment
         --------------

- --------------------
     /2/In addition to the foregoing, disposal of affected record categories
must cease once James River receives (i) notice of a scheduled Office of Federal
Contract Compliance Programs ("OFCCP") or Wage and Hour Division ("W&H") audit;
(ii) notice of a charge filed with the National Labor Relations Board ("NLRB"),
the Equal Employment Opportunity Commission ("EEOC") or similar state or local
agency; (iii) notice of a lawsuit; or (iv) James River becomes aware of an
actual or threatened investigation or other legal action. In all such cases, you
must immediately suspend disposal of any records relating to the matter and
contact the James River Legal Department for further guidance.

                                  APPENDIX A

     The most significant federal laws and regulations affecting human resources
(personnel) records are the following:

     A.   Fair Labor Standards Act ("FLSA") - establishes overtime and minimum
wage requirements. The FLSA requires retention of payroll records, labor
contracts, employment contracts, wage rate schedules, work schedules, time cards
and the like. The Department of Labor's Wage and Hour Division enforces the FLSA
regulations in this area found at 29 CFR 516.

     B.   Equal Pay Act - prohibits discrimination in wages between male and
female employees performing the same work. FLSA record-keeping requirements
apply. In addition, employers must retain any records explaining wage
differentials for employees of the opposite sex.

     C.   Federal Insurance Contribution Act ("FICA") and Federal Unemployment
Tax Act ("FUTA") - regulations implementing these statutes require retention of
records related to Social Security contributions and unemployment tax payments,
respectively. The record-keeping requirements are enforced by the Internal
Revenue Service and are found at 26 CFR 31.6001-1 and 31.6001-4.

     D.   Title VII of the Civil Rights Act of 1964 ("Title VII") - prohibits
employment discrimination based on race, sex, religion and national origin.
Regulations implemented by the Equal Employment Opportunity Commission ("EEOC")
require retention of various personnel documents, including applications,
training and selection materials (29 CFR 1627).

     E.   The Age Discrimination in Employment Act ("ADEA") - prohibits
workplace discrimination on the basis of age (over 40). EEOC regulations under
the ADEA require retention of records pertaining to such areas as promotions,
advertisements, and payroll information.


                                     VI-37
<PAGE>
 
     F.   Americans with Disabilities Act ("ADA") - effective July 26, 1992 for
employers of 25 or more employees and effective July 26, 1994 for employers of
15 or more employees, Title I of the ADA prohibits employment discrimination
against persons with disabilities. The EEOC has proposed to amend its
regulations on record-keeping and reporting under Title VII to add record-
keeping and reporting requirements under the ADA. The EEOC has said that the
public record-keeping burden will not increase as a result of the amendments
because all employers affected by them are already required to retain these
records for the same time periods under Title VII.

     G.   Rehabilitation Act of 1973* - prohibits discrimination against
individuals with handicaps by employers with federal contracts over $2,500.

     H.   Executive Order 11246* - requires federal contractors to take
affirmative action to prevent discrimination against employees on the basis of
race, sex, religion, color or national origin.

     I.   Vietnam-Era Veterans' Readjustment Assistance Act of 1974* - requires
employers with federal contracts in excess of $10,000 to take affirmative action
in hiring and promoting Vietnam-era and disabled veterans.

     J.   Employee Retirement Income Security Act ("ERISA") - establishes a
comprehensive statutory framework regulating retirement and welfare benefit
programs, establishes the Pension Benefit Guaranty Corporation to insure
benefits under defined benefit plans, and imposes extensive disclosure and
reporting requirements on employers maintaining such plans. Records relative to
complying with ERISA must be retained by statute a minimum of six years.

     The record retention requirements of the employment statutes cited above
overlap in many respects. The longest retention period specified by any single
regulation or statute is what is required by the James River Program.
- -------------------- 

*Although statute requires affirmative action by all covered employers, only
those with 50 or more employees and federal contracts of at least $50,000 are
required to maintain written affirmative action programs.  These statutes are
enforced by the U.S. Department of Labor's Office of Federal Contract Compliance
Programs ("OFCCP").

                         INSURANCE AND RISK MANAGEMENT
                         -----------------------------


1.   SCOPE

     As used in the James River Records Management Program, "insurance and risk
management" includes all formal insurance, reinsurance and risk management
programs which either attempt systematically to reduce the risk of third party
losses or provide for third party claims management, defense or payment.
Insurance and risk management do not include employee claims related to working
conditions (see "Human Resources" and "Safety and Health"), product research,
            ---
design and manufacturing (see "Product Development, Research and Testing"), or
                          --- 
environmental claims growing out of manufacturing processes that may impact the
environment, unless such claims are covered by insurance policies (see
                                                                   --- 
"Environmental").

2.   PURPOSE

     The purposes of this section are to insure that James River retains the
originals of all insurance policies (unless the transfer or disposal has been
specifically directed by the James River Legal Department) and to provide for
the organization and resolution of claims and the retention of records important
to the investigation and resolution of subsequent claims.

3.   CONSIDERATIONS

     Insurance contracts represent legal protection that James River has
purchased, and contracts often include reciprocal obligations of the company.
Because of these obligations, the long potential useful life of some equipment
and the lengthening of time in which certain classes of claims may be asserted,
James River must exercise particular care to retain the originals of all
insurance contracts and correspondence relating to coverage for the required
periods. Moreover, due to the sometimes cumulative nature of certain product- or
conduct-related claims, ready access to previous files may expedite the
investigation and resolution of subsequent claims. Accordingly, it is important
to keep files related to the insurance contracts themselves, their
interpretation and amendments, and the resolution of potentially recurring
claims.

                       -------------------------------
                             AND OTHER REAL ESTATE
                             ---------------------

1.   SCOPE

     As used in the James River Records Management Program, "real property
documents" are documents that evidence or establish James River's rights or
obligations related to real estate and related property, including land,
buildings and improvements, water and riparian rights, and timber and timber-
cutting rights. It does not include equipment, furniture, and other items that
are readily movable without damaging the affected land or building. These rights
or obligations can include the ownership, occupation, management, use,
acquisition or disposition of such property interests.

2.   CONSIDERATIONS

     Documents that evidence or establish James River's rights or obligations
with respect to property typically have long-lasting or permanent effects and as
a general rule should be retained permanently.

3.   RECORDATION

     Documents that meet the requirements for being recorded or filed in local
land records offices (which usually include, at a minimum, notarized documents)
must be recorded whenever recordation is necessary to secure James River's
interest (such as deeds and lease memoranda).*

4.   MANDATORY RECORDS

     A file should be maintained for each piece of property in which James River
claims an interest or bears any obligation. (If two or more property interests
are affected by the same real estate documents [such as parcels of land that
came into James River's ownership by separate deeds, but that were subsequently
made the subjects of the same leases or operating agreements], it may be
practical to maintain one comprehensive file that covers the consolidated
property interests.)

- ----------------------

     *If there is any doubt regarding whether a document should be recorded,
contact the James River Legal Department.


                                     XIV-2
<PAGE>
 
     Property files must be retained for the period during which James River has
rights or obligations plus seven years, and they may thereafter be discarded
with the approval of the James River Legal Department.

     Each file should contain the following:

     A.   Original documents that establish the interest or obligation. This
category includes original deeds, original leases, nondisturbance or recognition
agreements (establishing direct relationships between mortgagees and tenants or
between landlords and subtenants), maintenance agreements, easement agreements
(agreements that create perpetual property interests, other than ownership
interests--such as right-of-way agreements) and license agreements (usually
temporary or revocable agreements, often requiring periodic fee payments but
which technically may not create real property interests under applicable state
law). If the original is unavailable, the file should contain the best copy
available together with a notation of the location of the original and any
recording information.

     B.   The agreements pursuant to which the property was purchased or sold
and related correspondence.

     C.   Documents that evidence James River's expenditures or receipts with
respect to the property interest or obligation, such as settlement statements,
recordation receipts and costs of capital improvements.

     D.   Original policies of title insurance.

     E.   Documents that describe or identify the real property, such as plats,
maps, surveys or legal descriptions. Information identifying the preparer of
plats or surveys should be retained as well, since professional surveyors often
retain permanent files that include field notes.

     F.   Documents that evidence or establish value, such as appraisals
(including those made for purposes of tax contests and those made with a view
toward acquisition or disposition) and tax assessment notices.

5.   DUPLICATES


                                     XIV-3
<PAGE>
 
     There may be a legitimate need to retain multiple copies of some documents.
For example, it might be practical to maintain one file containing copies of all
leases and deeds for real estate used in a particular operation or business
unit.

     A.   In some cases James River may elect to keep copies of leases and
similar agreements for precedential value when dealing with the same contracting
party in the future.

                                   MARKETING
                                   ---------


1.   SCOPE

     As used in the James River Records Management Program, "marketing" includes
all efforts to identify and develop a market for James River's products,
including identifying markets for current and potential products, assessing the
current state of the market (including competitive prices and strategies),
product advertising, assessing competitive alternatives and devising sales and
marketing strategies. Marketing effectively fills the functional area between
manufacturing (see "Product Development, Research and Testing") and sales and
               --- 
distribution (see "Sales and Distribution"). It does not include institutional
              --- 
advertising (see "Public, Governmental and Investor Relations"). This section is
             ---
directed to persons and records associated with marketing.

2.   CONSIDERATIONS

     James River's markets are dynamic and fast-moving. Out-of-date marketing
information is seldom useful and infrequently used. Accordingly, except in
special circumstances described below, keep only current marketing data, plans
and projections and contractual documents indicated below.

3.   MANDATORY RECORDS

     To the extent that the marketing function is involved in the creation of
the following records, they must be retained as follows:

     A.   Contracts and Agreements
          ------------------------

     Records relating to contracts for market research or with consultants and
other third party contractors who undertake marketing or related work for James
River are records that must be retained as specified in "Contracts and
Agreements".

     B.   Product Descriptions
          --------------------

     Written or pictorial representations of the characteristics or performance
of products manufactured or sold by James River which may have been distributed
outside of James River to potential purchasers or users must be retained as
specified in "Sales


                                     XIV-5
<PAGE>
 
and Distribution". Records supporting product or performance representations
must be kept as specified in "Product Development, Research and Testing".

4.   DOCUMENTS TO BE RETAINED ONLY IN LIMITED SITUATIONS

     A.   Field or Sales Reports
          ----------------------

     Routine sales reports should be read and discarded within 90 days unless
                                                                       ------
they contain specific information describing the performance or creditworthiness
of a distributor or customer or contain competitive market information.
Distributor or customer information should be maintained in the dealer files or
by the Credit Department (see "Sales and Distribution" and "Financial Records").
                          ---  
     Information about and materials created by competitors, such as product
descriptions, prices, price lists, trade programs and similar information, must
be obtained only from customers, distributors, suppliers, and similar sources.
Immediately initial, date and identify such information by source (e.g.,
                                                                   -----
"Received 6/12/__ from XYZ Supplier, Atlanta, GA.  JEC").  Except when such
information is used to support a reduced price or enhanced service to meet a
competitive offer, these materials should be discarded when no longer used (see
                                                                            ---
Meeting Competition Documents in "Sales and Distribution").

     B.   Market Analysis
          ---------------

     James River records which assess market shares or attempt to identify
competitors' strategies, prices or support programs should be discarded when no
longer current unless they become Meeting Competition Documents (see above) or
               ------
were used to justify significant changes in prices, programs or practices (these
records should be kept for four years).

     C.   Annual, Five-Year, etc. Marketing Plans
          ---------------------------------------

     Keep only the current plan. Upon adoption of a plan, all drafts and
supporting research should be discarded (the final thoughts and goals are
embodied in the plan), and copies of previous plans should similarly be disposed
of since they have been replaced by the new plan.

     D.   Sales Projections
          -----------------

     Handle as Annual Marketing Plans (see above).

                   PRODUCT DEVELOPMENT, RESEARCH AND TESTING
                   -----------------------------------------


1.   SCOPE

     As used in the James River Records Management Program, "product
development, research and testing" includes all efforts to design, engineer and
manufacture James River's current and potential products, as well as its ongoing
quality and safety evaluations of these products. It does not cover patent and
intellectual property files maintained by or under the supervision of the James
River Patent Department.

2.   CONSIDERATIONS

     The purpose of this section is to ensure that James River retains for an
appropriate period records which substantiate the history and development of its
products, the care exercised in product testing and manufacture, the
consideration given to product warnings and related communications, and to
document the component materials utilized by James River in product manufacture.
This information could be relevant to product liability claims or consumer
advisory matters.

3.   MANDATORY RECORDS

     James River markets products with varying periods of useful life. For the
purposes of this Records Management Program, James River's products may be
divided into four categories: (1) chemically inert consumables, such as towels,
tissues, and business papers;* (2) machinery; (3) products subject to FDA
requirements; and (4) chemically active products.

     For chemically inert consumables and machines, the product-related records
listed below should be retained six years beyond the foreseeable commercially
useful life of these products.  Example:  Documents relating to a tissue
production run should be retained for six years after the fiscal year in which
the tissue was produced.  Documents relating to a machine with an expected
useful life of 10 years (including 

- -------------------------

     *Note:  Any product that contains a measurable quantity of any chemical
listed by EPA, FDA or OSHA must be treated as "chemically active" for the
purpose of this Records Management Program.



                                     XIV-7
<PAGE>
 
rebuilds) should be kept for 16 years after the fiscal year in which the machine
was manufactured.

     For products and processes representing potentially patentable inventions,
the product-related records listed below, especially research and development
log books, should be maintained for fifteen years.

     For products subject to FDA requirements, product-related records listed
below should be retained for ten years, except that FDA guarantee letters should
be retained for fifteen years after their expiration.

     For chemically active products, product-related records should be retained
permanently.

     The required product-related records are as follows:

     a.   Design manuals
     b.   Documents noting compliance with industry, voluntary and governmental
          manufacturing and safety standards
     c.   Engineering change orders, including reasons for changes
     d.   Engineering drawings and blueprints
     e.   Finished product inspection reports
     f.   Instrument or equipment calibration and inspection records
     g.   Manufacturing specifications, including work orders, quality control
and inspection records, etc.
     h.   Packaging requirements
     i.   Positive and negative feedback concerning the product
     j.   Product testing data, including tests by outside laboratories
     k.   Purchase order specifications
     l.   Quality control manuals
     m.   Records concerning product serial numbers, data codes, etc.
     n.   Records concerning components utilized in the manufacturing process,
including vendor purchase orders, component specifications, etc.
     o.   Research and development log books


                                     XIV-8
<PAGE>
 
     p.   Warranties, warnings, any instructions issued with products, and
          advertising copy referring to product safety or performance

     Note:  Except when different, longer periods are specified elsewhere (e.g.,
                                                                           -----
"Financial Records"), after five years, mandatory records can be transferred to
microfilm, computer output microfilm, electronic imaging or similar recording
system, provided that the system documentation is followed.
        --------

4.   GENERAL RULE

     All other documents concerning product development, research and testing,
not listed above, should be discarded upon their last use. Research and testing
files relating to potential products, which were rejected before being marketed
commercially, can be discarded as the projects are abandoned.

                  PUBLIC, GOVERNMENTAL AND INVESTOR RELATIONS
                  -------------------------------------------


1.   SCOPE

     James River generates numerous documents and records relating to its
activities involving the general public, governments and James River's equity
and debt investors.

     This section is directed to all non-litigation activities relating to
relations and communications with the public, governments and investors, except
for specific categories such as "Environmental", "Human Resources", "Product
Development, Research and Testing", and "Safety and Health".

     Retention and dissemination of such materials and information are
frequently mandated by law, such as the securities laws, and also may be
required by contractual arrangements with holders of debt or equity securities
of the company.

2.   CONSIDERATIONS

     Proper record-keeping is necessary to establish compliance with statutory,
regulatory and contractual requirements; allow management to prepare additional
documents or update documents based upon previously prepared materials; and
allow management to interpret business performance and to make business
decisions based upon the public's response to company actions.  In addition,
retaining public documents provides a useful record of James River's history and
assists the company in responding to future inquiries.

3.   MANDATORY RECORDS

     The following is a list of the records that must be maintained and the
applicable retention periods.  Except in rare cases, drafts should not be
retained.  The final version alone has operative force, and no useful purpose is
served by keeping drafts.

                               -----------------


1.   SCOPE

     The Occupational Safety and Health Administration (OSHA) has statutory
authority to regulate workplace safety. Employer obligations include the
collection and retention of specific safety and health information. This Program
is directed to these obligations.

2.   CONSIDERATIONS

     Penalties under the Occupational Safety and Health Act are increasing
markedly as a result of legislative and enforcement changes. OSHA has also
reemphasized record-keeping requirements and frequently cites employers for
"willful" OSHA violations and violations of other criminal laws.

</TABLE> 

4.   GENERAL MANDATORY RECORDS

     General records of employee exposure and medical records ((S) 1910.20) must
be retained for a period of thirty years. In addition to this general
requirement, there are more specific requirements associated with chemical-
specific standards - i.e., the lead standard (29 C.F.R. (S) 1910.1025). If your
                     ----
employees are exposed or potentially exposed to chemicals for which OSHA has
issued a specific standard, the record-keeping requirements for that standard
must be reviewed and followed. Specific questions regarding specific standards
or requirements should be directed to James River Corporate Safety and Health or
James River Legal Departments.

5.   DOCUMENTS TO BE RETAINED ONLY IN LIMITED SITUATIONS

     Non-mandatory safety and health records relating to non-employment-related
medical claims should be kept for two years after the matters are resolved.
Workers Compensation claims should be kept for the longer of three years after
all claims are resolved or the time limit in your state for reopening claims.

6.   GENERAL RULE

     All records not identified above should be discarded when no longer used.
Superseded abatement plans should be discarded when replaced.  Drafts and
surveys should be discarded when the contents have been transferred to reports.
Any records that relate to a matter in litigation should be retained
permanently.  If a document may be involved in litigation, contact the James
River Legal Department for guidance.

                            SALES AND DISTRIBUTION
                            ----------------------

1.   SCOPE

     As used in the James River Records Management Program, "sales" includes all
efforts to identify and sell a particular product to a customer for consumption
by the customer, resale in modified form or resale in combination with other
products.  "Distribution" includes marketing a product to or through a customer,
which resells or distributes it relatively intact.  In this section, dealer and
distributor will be used interchangeably.

2.   CONSIDERATIONS

     Because sales and distribution directly affect James River's products and
customers, they are key components in James River's external relations.  Thus,
documents which either make representations about a product's performance or
define James River's legal or other obligations regarding a product or a
customer should be carefully maintained for the specified periods.

     Documents which describe, interpret or alter distributor agreements should
also be maintained. If there is no single document which constitutes the
distributor agreement, all documents which define James River's obligations and
the distributor's performance should be maintained.

3.   MANDATORY RECORDS

     A.   Product Descriptions
          --------------------

     Written or pictorial representations of the characteristics or performance
of products manufactured or sold by James River should be dated and retained for
six years after the useful life of the product (including rebuilds). Documents
supporting product characteristics or performance claimed by James River should
be retained for the same period (see "Product Development, Research and 
                                 ---
Testing").

     B.   Contracts
          ---------

     Copies of all current distributor agreements and all letters and other
external correspondence which interpret, explain or apply the current agreement
should be maintained for six years after the agreement is replaced by a new
agreement or 

                                    XIV-15
<PAGE>
 
otherwise terminated. If the agreement contains a warranty or limitation of
rights or remedies against James River, it should be kept for the longer of six
years after the useful life of the product (including rebuilds) or six years
after the agreement is replaced by a new agreement.

     Where no single document constitutes the distributor agreement, the
distributor's file should contain all records describing or referring in any way
to the dealer's obligations and limitations on the dealer for the greater of two
years after James River issues the dealer a new agreement or six years after
James River terminates or declines to renew the agreement.

     C.   Dealer Performance
          ------------------

     All documents which contain specific information evaluating or reporting on
the dealer's performance should be kept for two years after James River issues
the dealer a new agreement and six years after James River terminates or
declines to renew the agreement.

     Where there is no written dealer agreement, all documents which contain
specific information on the dealer's performance should be kept for six years.

     D.   Other Contracts
          ---------------

     Non-dealer contracts relating to sales and distribution services must be
retained as described in "Contracts and Agreements".

4.   DOCUMENTS TO BE RETAINED ONLY IN LIMITED SITUATIONS

     A.   Routine Sales Reports
          ---------------------

     Routine sales reports should be read and discarded within 90 days unless
                                                                       ------
they contain specific competitive information or information on the performance
or creditworthiness of a dealer or a customer or record specific conversations
with a dealer or customer regarding legal relations, contract meaning or
performance. Such documents dealing with the dealer or contract should be
maintained in the dealer files (see 3[C]). Competitive information should be
                                ---
maintained as Competitive Information (see below).

     B.   Competitive Information
          -----------------------

                                    XIV-16
<PAGE>
 
     General information received from customers or similar sources (but never
directly from competitors) should immediately be identified by the source and
date received.  Such information should be kept while current, unless it is used
to justify a lower price in order to meet competition (see Meeting Competition
                                                       ---
Materials).

     Materials created by competitors, such as product descriptions, price lists
and the like, should be obtained only from customers, distributors, suppliers,
and similar sources. Such information should be immediately initialed, dated and
identified by source (e.g., "Received 6/12/__ from XYZ Supplier, Atlanta, GA.
                      ----
JEC").  Except when such information becomes Meeting Competition Materials (see
below), these materials should be discarded when no longer used.

     C.   Meeting Competition Materials
          -----------------------------

     Antitrust laws permit a company to charge competing customers different
prices for several reasons, including good faith attempts to meet competing
prices from competitors. This is called "good faith meeting competition".

     Where James River offers a customer better terms in a good faith effort to
meet competition, reports of competitive activity and other information
describing the offer being met or offering a basis for believing the customer's

     The Records Management Committee has addressed numerous requests for

identify every record to be created and maintained, the Committee has deemed
that it would be useful to periodically publish Guidelines documenting its

harmless the Company, WinCup and the Partnership from and against all demands,
claims, actions, assessments, losses, damages, liabilities, costs and expenses,
including without limitation attorney's fees and expenses, arising out of or
related to the breach or inaccuracy of any representation or warranty made by
KCTC herein.

         5.2  By the Company. The Company hereby agrees to indemnify, defend and
              --------------

losses, damages, liabilities, costs and expenses, including without limitation
attorney's fees and expenses, arising out of or related to the breach or
inaccuracy of any representation or warranty made by the Company, WinCup or the

         5.3  Procedure.  A party seeking indemnification hereunder (the

"Indemnified Party") shall give the other party (the "Indemnifying Party")
prompt notice of any claim for indemnity hereunder, and the Indemnifying Party
shall thereafter undertake the defense, settlement or compromise thereof by
representatives chosen by it.  The failure of the Indemnified Party to promptly
notify the Indemnifying Party shall not relieve the Indemnifying Party of its
obligations hereunder unless such failure adversely prejudices the Indemnifying
Party's ability to defend such claim.  If the Indemnifying Party, within a
reasonable time after notice of any such claim, fails to defend, the Indemnified
Party will (upon further notice to the Indemnifying Party) have the right to
undertake the defense,

                                      -8-
<PAGE>
 
compromise or settlement of such claim on behalf of, and for the account and
risk of, the Indemnifying Party, subject to the right of the Indemnifying Party
to assume the defense of such claim at anytime prior to settlement, compromise
or final determination thereof. Notwithstanding the foregoing, (a) if there is a
reasonable probability that a claim may materially and adversely affect the
Indemnified Party other than as a result of money damages or other money
payments, the Indemnified Party shall have the right, at the Indemnifying
Party's cost and expense, to defend, compromise or settle such claims and (b)
the Indemnifying Party shall not, without the written consent of the Indemnified
Party, settle or compromise any claim or consent to the entry of any judgment
which does not include as an unconditional term thereof a release of the
Indemnified Party from all liability in respect of such claim.

     6.  Miscellaneous.

Documents and any renewals, extensions and modifications thereof (all of the
foregoing obligations being hereinafter collectively referred to as the
"Obligations").

          2.  Modification.  From and after the Effective Date, and subject to

the provisions of Section 4 of the Note, the outstanding principal balance of
the Indebtedness shall bear interest at a rate equal to 100 basis points higher
than the rate set forth in the Term Loan Notes by the Transferee as maker
delivered pursuant to the Revolving Credit, Term Loan and Security Agreement
dated as of the date hereof among Transferee, Transferor, NationsBank, N.A. and
Bank of New York Commercial Corporation, as lender and as agent (the "Term
Notes"), as such rate is adjusted from time to time as set forth in such Term
Notes; provided, however, that if the Transferee and Transferor satisfy their
obligations in full under the Term Notes at any time while there remains any
principal outstanding under the Note, such unpaid principal shall bear interest
at an annual rate equal to the prime rate, as published in The Wall Street
Journal three business days prior to the last day of each calendar quarter, plus
200 basis points.  Such interest shall be payable as follows:

              (a) Interest. Interest accrued on the Indebtedness through the

Transferor making any payment to James River Paper Company, Inc. or any
successor thereto or any person or entity to whom James River Paper Company,
Inc. may assign its interest in Transferee (James River Paper Company, Inc. or
any such successor or assignee being hereinafter referred to as "JR") in
connection with either (i) the exercise by JR of its right to require Transferor
to redeem all of JR's interest in Transferee commencing five years from the
Effective Date or on such earlier date as Transferor may permit JR to exercise
such right, as set forth in Transferee's Agreement of Limited Partnership dated
as of the Effective Date between Transferor and JR (the "Partnership Agreement)
or (ii) the exercise by Transferor of its right to acquire all of JR's interest
in Transferee under the Partnership Agreement.

          The foregoing terms shall be set forth in an allonge to be affixed to

                             EMPLOYMENT AGREEMENT
                             --------------------


         THIS AGREEMENT is made as of this 5th day of April, 1996, by and among

         The parties hereto desire to enter into this Agreement to provide for

Term(s) are hereinafter referred to, collectively, as the "Term."

         3.   Duties.
              ------ 

              Executive is engaged hereunder as Vice President and Treasurer of
Employer and agrees to perform such duties and services as are customarily
incident to such offices and such other duties and services as may be assigned
to him from time to time by the Board.  During his employment hereunder,

of Employer; and shall not undertake or engage in any other business activity
which interferes with the performance of his duties without the prior written
consent of Employer, except as stated in Paragraph 9(a)(v) below.

         4.   Compensation.

this Agreement by all the parties hereto, (b) a base salary of One Hundred
Twenty Five Thousand Dollars ($125,000) per annum, payable in equal semi-monthly

                                      -2-

Salary shall be reviewed annually during the Term and may be increased in the
sole and absolute discretion of the Board based on corporate policy and
Executive's performance.

         5.   Expenses.
              -------- 

              Executive is authorized to incur reasonable expenses for promoting
Employer's business, including expenses for entertainment, travel, and similar
items.  Employer will reimburse Executive for all such expenses upon
presentation by Executive of appropriate vouchers itemizing such expenditures in

entitled to such benefits of employment with Employer as are now or may
hereafter be in effect for salaried officers and employees of Employer including
without limitation such insurance, disability, medical, dental and other benefit
plans or programs as are now or hereafter established or maintained by Employer

reasonable moving expenses and relocation costs arising on account of any
relocation of Executive's residence within the first year of this contract.

cartage company charges, hotel charges and meal costs. Relocation costs include,
but are not limited to, broker's commissions, loan closing costs, discount
points and other costs incident to the sale of Executive's current residence and

         7.   Termination of Employment.
              ------------------------- 

              a.   Death of Executive.  In the event of the death of Executive
                   ------------------                                         
during the Term, this Agreement shall terminate and Employer shall have no
further obligation or liability hereunder except to pay to Executive's executor
or administrator the portion, if any, of the Compensation earned by Executive
for the period through the date of Executive's death, unless previously paid.

              b.   Total Disability.  In the event of a mental or physical
                   ----------------                                       
condition which in the reasonable opinion of the Board, based upon the
independent medical diagnosis of a physician engaged by Employer for that
purpose, renders Executive unable or incompetent to perform his duties hereunder
("Total Disability"), which condition continues for a period of ninety (90)
consecutive days during the Term of this Agreement, Employer shall have the
right to terminate Executive's employment hereunder by giving

                                      -4-
<PAGE>
 
Executive ten (10) days' written notice thereof and, upon expiration of such
ten-day period, Employer shall have no further obligation or liability under
this Agreement except to pay to Executive the portion, if any, of Executive's
Compensation for the period through the date of termination which is due and
remains unpaid.

              c.   Resignation.  Executive may voluntarily terminate his
                   -----------                                          
employment under this Agreement by giving Employer written notice effective at
the end of the current Term, not less than ninety (90) days prior to the
expiration thereof.  Following the effective date of such resignation, Employer
shall have no further obligation or liability under this Agreement except to pay
to Executive the unpaid portion, if any, of the Executive's Compensation for the
period through the effective date of Executive's resignation which is due and
remains unpaid.

              d.   Discharge for Cause.  The Employer may discharge Executive
                   -------------------                                       
and thereby immediately terminate his employment under this Agreement at any
time for Cause (as hereinafter defined).  "Cause" shall be defined as (a) gross
negligence of Executive; (ii) willful failure by the Executive to perform his
duties under this Agreement or material breach of any agreement made by
Executive herein which breach continues uncured for a period of thirty (30) days
after Executive has received written notice thereof; (iii) embezzlement or
conversion by Executive to his own use of any funds of Employer or any client of
Employer; (iv) destruction or conversion to his own use by

                                      -5-
<PAGE>
 
Executive of any property of Employer, without Employer's consent; (v)
Executive's conviction of a felony; (vi) Executive's adjudication as an
incompetent; (vii) Executive's habitual intoxication; or (viii) Executive's drug
addiction. Employer's determination that Cause for termination of Executive's
employment hereunder exists shall be made in good faith by a majority of its
directors (other than Executive in the event Executive shall be a director of
Employer) based upon reasonable evidence presented to such directors. In the
event of termination for Cause, the Employer shall have no further obligations
or liabilities to Executive hereunder, except to pay to Executive, subject to
any claim which Employer may have against Executive for damages, the portion, if
any, of Executive's Compensation for the period through the date of termination
which is due and remains unpaid.

         8.   Non-Disclosure of Trade Secrets and Other Information.
              ----------------------------------------------------- 

              Executive agrees that he will not, during the Term of this
Agreement or at any time thereafter, use for himself or divulge to others any
secret or confidential information, knowledge, or data of Employer, developed by
him or obtained by him as a result of his employment, unless authorized by
Employer in writing. It is understood that this applies to information of either
a technical or commercial nature, including secret processes, formulas,
machinery, utensils, manufacturing techniques and arts, customer lists, market
information and the like. The terms 'secret' and 'confidential' shall include
all

                                      -6-
<PAGE>
 
unpublished information and all information and data known to some but not to
all members of the trade or industry to whom such information or data would be
in any manner useful, but not information which Executive obtained, knew or
developed prior to commencing employment with Employer, whether published or
not.

              All memoranda, notes, records, or other documents made or compiled
by Executive, or made available to Executive while employed by Employer, are
Employer's property and all copies thereof shall be delivered to Employer on
termination of Executive's employment or at any other time upon the request of
Employer.

         9.   Restrictive Covenant.
              -------------------- 

              a.   Non-Competition.
                   --------------- 

                   Executive agrees that, so long as he is employed by Employer
pursuant to this Agreement, he will not, directly or indirectly, as a sole
proprietor, member of a partnership, stockholder, investor, officer or director
of a corporation, or as an employee, agent, associate or consultant of any
person, partnership or corporation other than Employer or in any other capacity
except as provided in Paragraph 9(a)(v) below:

                   (i)   own, manage, operate, participate in, perform services
for or otherwise carry on a business similar to or competitive with the business
of Employer within the United States; provided that ownership of not more than
five percent (5%) of the issued and outstanding shares of a class of securities
of a corporation the securities of which are traded on

                                      -7-
<PAGE>
 
a national security exchange or in the over-the-counter market shall not be
deemed ownership of the issuer of such shares for the purposes of this section;

                   (ii)  induce or attempt to persuade any employee of Employer
or any of its affiliates to terminate such employment relationship in order to
enter into any such relationship with such person or to enter into any such
relationship on behalf of any other business organization in competition with
Employer or any of its affiliates;

                   (iii) solicit any business related to the business conducted
by Employer from any clients, customers, or prospective or former clients or
customers of Employer or its affiliates; or

                   (iv)  perform services of any nature for any entity which
engages in or conducts any business that competes with, restricts or interferes
with the business of Employer.

                   (v)   Nothing in this Paragraph 9(a) shall be construed to
prevent the Executive from taking advantage or developing corporate
opportunities which have first been presented to Employer for development, but
which Employer elects not to pursue.

                                      -8-
<PAGE>
 
              b.   Injunctive Relief.  Without limiting the right of Employer or
                   -----------------                                            
any of its successors or permitted assigns to pursue all other legal and
equitable rights available to it for violation of the covenants set forth in
subparagraph 9(a) hereof, it is agreed that such other remedies cannot fully
compensate Employer and its successors and assigns for such a violation and that
Employer and its successors and assigns shall be entitled to injunctive relief
to prevent violation or continuing violation hereof.  It is the intent and
understanding of each party hereto that if, in any action before any court or
agency legally empowered to enforce this covenant, any term, restriction,
covenant or promise is found to be unreasonable and for that reason
unenforceable, then such term, restriction, covenant or promise shall be deemed
modified to the extent necessary to make it enforceable by such a court or
agency.

         10.  Arbitration.
              ----------- 

              Except as provided in subparagraph 9(b) hereof, any controversy or
claim arising out of or relating to this Agreement or the breach thereof shall
be settled by arbitration in Philadelphia, Pennsylvania, in accordance with the
rules of the American Arbitration Association and any decision made in
accordance with such rules shall be binding on all parties in interest, and
judgment upon any award rendered may be entered in any court having jurisdiction
thereof.

                                      -9-
<PAGE>
 
         11.  Waiver of Breach.
              ---------------- 

              The waiver by Employer or Executive, as the case may be, of a
breach of any provision of this Agreement by Executive or Employer, as the case
may be, will not operate or be construed as a waiver of any subsequent breach by
Executive or Employer, as the case may be.

         12.  Entire Agreement.
              ---------------- 

              This instrument contains the entire Agreement of the parties with
respect to the employment of Executive by Employer.  It may not be changed
orally, but only by an agreement in writing signed by the party against whom
enforcement of any waiver, change, modification, extension or discharge is
sought.

         13.  Severability.
              ------------ 

              If any provision of this Agreement shall be invalid or
unenforceable, in whole or in part, such provision shall be deemed to be
modified or restricted to the extent and in the manner necessary to render the
same valid and enforceable, or shall be deemed excised from this Agreement, as
the case may require, and this Agreement shall be construed and enforced to the
maximum extent permitted by law, as if such provision had been originally
incorporated herein as so modified or restricted, or as if such provision had
not been originally incorporated herein, as the case may be.
