                           FORWARD LOOKING STATEMENTS

     When used in this Form 10-Q, the words or phrases "will likely result",
"are expected to", "will continue", "is anticipated", "estimate", "projected",
"intends to" or similar expressions are intended to identify "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. Such statements are subject to certain risks and uncertainties,
including but not limited to risks associated with our credit facilities and
liquidity, the ability to obtain adequate financing on commercially acceptable
terms, economic conditions, the affects of rapid growth upon the Company and the
ability of management to effectively respond to such growth, demand for products
and services of the Company, newly developing technologies, the Company's
ability to compete, regulatory matters, protection of the Company's proprietary
technology, the effects of competition from entities with greater financial
resources than that possessed by the Company and shareholder dilution. Such
factors, which are discussed in "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and the notes to consolidated
financial statements, could affect the Company's financial performance and could
cause the Company's actual results for future periods to differ materially from
any opinions or statements expressed with undue reliance on any such
forward-looking statements, which speak only as of the date made. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

                   U.S. PLASTIC LUMBER CORP. AND SUBSIDIARIES

         NOTES TO CONDENSED UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1.  NATURE OF OPERATIONS AND BASIS OF PRESENTATION

     NATURE OF OPERATIONS

     U.S. Plastic Lumber Corp. and its subsidiaries (collectively the "Company")
are engaged in the manufacturing of recycled plastic lumber and other products
and environmental remediation services, including recycling of soils that have
been exposed to hydrocarbons and the beneficial reuse of dredge materials. The
Company's plastic lumber customers are located throughout the United States,
although some customers are international. The Company's environmental
remediation, dredge and soil recycling customers are located primarily in the
Northeastern United States.

     BASIS OF PRESENTATION

     The Company's consolidated financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
reporting and the regulations of the Securities and Exchange Commission ("SEC")
for quarterly reporting. The interim consolidated financial statements should be
read in conjunction with the consolidated financial statements and notes thereto
included in the Company's annual report on Form 10-K as filed with the SEC for
the year ended December 31, 2000. Management acknowledges its responsibility for
the preparation of the accompanying interim condensed consolidated financial
statements which reflect all adjustments considered necessary, in the opinion of
management, for a fair statement of the results of interim periods presented.
The results of operations for the interim periods are not necessarily indicative
of the results of operations for the entire year. Where appropriate, certain
amounts have been reclassified to conform to the 2001 presentation.

2.  LIQUIDITY AND CAPITAL RESOURCES

     On September 28, 2001, the Company notified all of the banks which
participate in its Senior Credit Facility that due to lower than expected sales
at the plastic lumber division the Company could not make the $2.5 million term
loan payment due September 30, 2001 without jeopardizing its business
operations. In addition, the Company is not in compliance with some of the
covenants under the Senior Credit Facility as of September 30, 2001. The Company
is currently in negotiations for a waiver of its covenant violations and failure
to make the scheduled principal payment, as well as an amendment to the Senior
Credit Facility whereby the lenders under the facility would agree to accept
interest only payments from the Company and allow the Company to defer the
September 30, and December 31, 2001 principal payments until the earlier of
February 28, 2002 or the sale of some of the Company's assets. No assurance can
be given as to whether or in what form this waiver will be obtained.

     On October 4, 2001, the Company requested a suspension of principal
payments on its Master Credit Facility with GE Capital until the earlier of
March 31, 2002 or the sale of some of the Company's assets. Through November 14,
2001, the Company has continued to make all scheduled principal payments on its
Master Credit Facility but is continuing to negotiate the deferral of future
principal payments with GE Capital. As of September 30, 2001, the Company is not
in compliance with its tangible net worth covenant under the Master Credit
Facility. The Company is currently in negotiations with GE Capital to obtain a
waiver of this covenant violation as of September 30, 2001. The Master Credit
Facility contains a provision whereby an event which would accelerate payment
terms of the Company's Senior Credit Facility would also accelerate the payment
terms of the Master Credit Facility to the same due date as the Senior Credit
Facility.

     The Company expects to finalize the waivers and amendments to the Senior
Credit Facility and the Master Credit Facility in the near future. While the
covenant violations and failure to make a principal payment do constitute an
event of default under the respective agreements, as of November 14, 2001
neither lending group has taken any action against the Company. The lending
groups have been negotiating forbearance agreements with the Company, and the
Company believes it will be successful in obtaining the

                                        6

                   U.S. PLASTIC LUMBER CORP. AND SUBSIDIARIES

 NOTES TO CONDENSED UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

necessary waivers and forbearances from its lenders. However, in the event that
waivers and a deferral of principal are not obtained the lenders have the option
of declaring the Company in default and demand immediate repayment of the
outstanding balances of $38,800,000 and $11,899,000 of the Senior Credit
Facility and Master Credit Facility, respectively. The Company currently does
not have the financial resources to repay these debt obligations in the event
that they become immediately due without obtaining new debt and/or equity
capital and/or selling some of the Company's assets. Pursuant to the terms of
the Senior Credit Facility, upon the occurrence of an event of default, the
administrative agent for the lending banks, upon the request of the lending
banks, can declare all commitments terminated, and/or declare all Company loans
and other obligations due and payable.

     The Company's liquidity and ability to meet its financial obligations will
be dependent on among other things, the Company's ability to obtain waivers for
its debt covenant and payment violations as of September 30, 2001 and through
the date of this filing, maintain compliance with future debt covenants and
raise new capital through the issuance of additional equity, new debt financing
and/or sell some of the Company's assets.

     The Company is highly leveraged and during 2000 and the nine months ended
September 30, 2001, the Company suffered significant losses from operations,
primarily resulting from the expenses incurred in its plastic lumber division
related to the expansion and start up of certain manufacturing facilities, the
inefficiencies in the production of certain products, increases in raw material
costs and interest expense. During the third quarter of 2001 the Company closed
three of its plastic lumber manufacturing facilities and agreed to sub-lease two
of its resin processing plants to third party raw material processors. In
connection with the exiting of these facilities, the Company eliminated
approximately 140 full time manufacturing positions, recorded asset impairment
charges of $9,810,000 and recorded a restructuring charge of $1,656,000 (see
Note 6). The Company's accumulated deficit and working capital deficit totaled
approximately $33,932,000 and $49,368,000, respectively, as of September 30,
2001.

     Since its inception, the Company has financed its operations through a
number of stock and debt issuances. During 2000 and the first nine months of
2001, the Company's primary sources of working capital have been the net
proceeds from sales of the Company's convertible preferred and common stock,
proceeds from its Senior Credit Facility, the issuance of convertible
subordinated debentures and direct sales of the Company's products and services
to its customers. As of December 31, 2000, the Company was not in compliance
with certain covenant requirements of its Senior Credit Facility and its Master
Credit Facility. The Company received waivers for these covenant violations as
of December 31, 2000 and entered into amendments to the Senior Credit Facility
and Master Credit Facility (see Note 4).

     The Company's material financial commitments relate principally to its
working capital requirements and obligations to make term loan payments on its
Senior Credit Facility. As of September 30, 2001, the outstanding balance on the
Senior Credit Facility is $38,800,000. Under the terms of the proposed amended
Senior Credit Facility, the $2.5 million principal payments due September 30,
and December 31, 2001 would be deferred until February 28, 2002 or the sale of
some of the Company's assets. Additional principal payments in the amount of
$2.5 million each are due on March 31, and June 30, 2002. The remaining
outstanding balance would have to be refinanced or repaid on or before July 2,
2002. On or before July 1, 2002, the Company is also required to retire its
$4,000,000 convertible debenture issued to the Halifax Fund, L.P. ("Halifax"),
as well as the $5,000,000 convertible debenture payable to the Stout
Partnership, the Company's largest shareholder. Several members of the Company's
Board of Directors and a member of management are affiliated with the Stout
Partnership. The Company currently does not have the financial resources to
retire these debt obligations in 2002 and the Company will need to obtain new
debt and/or equity capital and/or sell certain assets to meet these
requirements.

                                        7

                   U.S. PLASTIC LUMBER CORP. AND SUBSIDIARIES

 NOTES TO CONDENSED UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     Additional financial obligations of the Company include interest payments
on the Senior Credit Facility of approximately $275,000 per month, lease
payments pursuant to certain real property and equipment leases of approximately
$203,000 per month, installment payments for manufacturing equipment of
approximately $240,000 per month, interest payments on the Company's Convertible
Subordinated Debentures of approximately $460,000 quarterly, and dividends on
the Company's Series D and Series E Convertible Preferred Stock of approximately
$231,000 quarterly. As of September 30, 2001 the Company has not made any
dividend payments on its Series D Convertible Preferred Stock. Dividends in
arrears pertaining to the Series D Convertible Preferred Stock amount to
$652,000 at September 30, 2001. There are no dividends in arrears with respect
to the Series E Convertible Preferred Stock.

     The terms of the Senior Credit Facility also required the Company to raise
$6,500,000 of equity or equity equivalents by February 28, 2002. During February
and March 2001, the Company raised $1 million through the issuance of its Series
"E" Convertible Preferred Stock (see Note 3). In June 2001, the Company raised
$4 million through the issuance of a subordinated convertible debenture, (see
Note 5) due July 1, 2002. Additionally, on July 3, 2001, the Company raised $1
million through the issuance of 952,381 shares of common stock (see Note 3). On
November 1, 2001 the Company raised an additional $800,000 through the issuance
of 1,334,000 shares of common stock. These private placement transactions were
not registered under the Securities and Exchange Act of 1934 (the "Act") in
reliance upon the exemption from registration in Section 4(2) of the Act, as
transactions not involving any public offering. With the completion of the
November 1, 2001 private placement transaction, the Company has now met the
financial covenant contained in the Senior Credit Facility pertaining to the
securing of equity or equity equivalents. However, the Company will also need to
raise additional capital by selling certain assets or obtaining additional
sources of debt or equity in order to meet its financial obligations.

     Some of the Company's debt instruments contain covenants establishing
performance measurement through various financial ratios and operating
restrictions. The Company's failure to comply with any covenant or material
obligation contained in these debt agreements or any of the Company's other debt
agreements, absent a waiver from the lenders, would result in an event of
default which could accelerate debt repayment terms under the debt agreements.
Due to various cross-default provisions contained within some of the Company's
credit agreements, an event of default under the senior debt agreements could
accelerate debt repayment terms under some of the other credit agreements, all
of which would have a material adverse affect on the Company's liquidity and
capital resources.

     Capital requirements relating to the implementation of the Company's
business plan have been and will continue to be significant. The Company
believes that its ability to generate cash from operations is dependent upon,
among other things, increased demand for its products and services and the
successful development of direct marketing, improved manufacturing efficiencies
and product distribution capabilities. There can be no assurance that the
Company will have sufficient capital resources to permit the Company to continue
implementation of its business plan.

     In November of 2000, the Company retained Bank of America Securities to
explore and evaluate strategic alternatives for the Company, which could include
the possible sale of the Company's environmental recycling division, Clean Earth
Inc. ("CEI"). No agreement has been reached with any prospective buyers and
there can be no assurances that an agreement will be reached. Proceeds from the
sale of CEI, if it occurs, would be used to first pay down the Company's Senior
Credit Facility. Any excess proceeds would be applied to some of the Company's
other debt obligations and provide working capital.

     While there can be no assurances, the Company believes its cash flows from
operations, the sale of certain assets, and/or the raising of additional capital
will satisfy its liquidity requirements through September 30, 2002. The Company
is seeking additional sources of financing to supplement its cash flow
requirements, however, there can be no assurance that any additional financing
will be available to the
                                        8

Company on acceptable terms, or at all. If the Company does not obtain the
necessary waivers and amendments from the lending groups for covenant violations
and failure to make scheduled principal payment as of September 30, 2001, comply
in the future with the covenants contained within its debt agreements, and if
adequate cash flow from operations, funds from the capital markets or proceeds
from the sale of assets are not available to finance the Company's operations
and retire its debt obligations as they become due, the Company will be required
to significantly curtail its operations and the Company's ability to continue as
a going concern would be impaired. The accompanying consolidated financial
statements do not include any adjustment that might result from the outcome of
these uncertainties.

     On September of 2001, the Company was advised by the Staff of Nasdaq
National Market that the Company's stock failed to maintain a minimum bid price
of $1.00 over the previous 30 consecutive trading days, and that in accordance
with the Nasdaq Market Place Rules, the Company had 90 calendar days, or until
December 5, 2001, to regain compliance. On September 28, 2001 the Company
received notification from Nasdaq that the listing qualification notice
previously received had been suspended until January 2, 2002. If the bid price
for the Company's common stock is not above $1.00 per share for at least 10
consecutive trading days prior to April 2, 2002, or if the Company fails to
comply with any other requirement for continued listing, the Company's common
stock will be delisted from trading on the Nasdaq National Market, subject to
the Company's right to appeal. If the Company's stock were to be delisted, it
may adversely impact the Company's ability to secure additional equity
financing.

3.  CAPITAL STOCK

     SERIES E CONVERTIBLE PREFERRED STOCK

     During February 2001 and March 2001, the Company issued a total 571,429
shares of its Series 'E" Preferred Stock to the Stout Partnership in exchange
for a payment to the Company of $500,000 on each of the aforesaid dates. The
stock pays a monthly cash dividend at an annual rate of 10%. Each share of
Series E Preferred Stock is convertible into one share of the Company's common
stock at the option of the holder at any time after December 31, 2001, subject
to certain rights of the Company. The Company at its sole option can redeem the
Preferred Stock at 110% of the initial purchase price in cash prior to December
31, 2001. In addition, if the common stock of the Company is trading at an
average closing price of $1.75 per share or higher for 20 consecutive trading
days at any time prior to March 1, 2002, the Company has the right, subject to
certain other conditions, to require conversion of the Series E Preferred Stock
into common stock. Otherwise, the Series E Preferred Stock automatically
converts into common stock on March 1, 2002.

     FUSION CAPITAL FUND II

     On December 7, 2000, the Company entered into a common stock purchase
agreement with Fusion Capital Fund II, LLC pursuant to which Fusion Capital
agreed to purchase up to $6.0 million of the Company's common stock subject to
increase, at the Company's discretion, by an additional $6.0 million, subject to
certain conditions. The $6.0 million of common stock purchasable under the first
tranche of the common stock purchase agreement is to be purchased over a
twelve-month period, subject to a 6-month extension or earlier termination at
the Company's discretion. The selling price of the shares will be equal to the
lesser of (1) $15.00 or (2) a price based upon the future market price of the
common stock without any fixed discount to the market price. Pursuant to the
terms of the agreement with Fusion Capital, the Company may not sell shares to
Fusion Capital until such time as the Securities and Exchange Commission
declares a registration statement effective which registers for resale the
shares Fusion Capital has agreed to purchase. As of September 30, 2001, the
Company had not filed a registration statement with the Securities and Exchange
Commission.

     On March 2, 2001 under the terms of the common stock purchase agreement,
Fusion Capital Fund II, LLC was issued 200,000 shares of the Company's common
stock as a commitment fee. The market value of these shares of $287,000 at the
time of issuance is reflected in prepaid expenses in the Company's balance
sheet. Unless an event of default occurs, these shares must be held by Fusion
Capital until the common stock purchase agreement has been terminated. On August
31, 2001 the common stock purchase agreement was amended whereby the Company
granted Fusion Capital warrants to purchase 100,000 shares of the Company's
common stock at an exercise price of $1.00 per share in exchange for Fusion
Capital's agreement to revise the terms under which Fusion Capital could
terminate the agreement. These warrants were valued at approximately $65,000 and
are being recorded as an additional commitment fee within prepaid expenses in
the Company's balance sheet.

     On July 3, 2001, the Company issued 476,191 shares of common stock to ZLP
Master Fund, LTD. and 476,190 shares of common stock to ZLP Master Technology
Fund, LTD. at a purchase price of $1.05 per share. This private placement
transaction was not registered under the Act in reliance upon the exemption from
registration in Section 4(2) of the Act, as a transaction not involving any
public offering. Net proceeds after issuance costs of approximately $983,000
were used for general corporate purposes. Because the Company did not, within 60
days of July 3, 2001, file a registration statement with the SEC to register the
resale of these shares as required under the stock purchase agreement, the
Company is required to pay a cash penalty fee to the purchasers of these shares
at a rate equal to 1.5% of the outstanding amount purchased for each 30-day
period that a registration statement is not filed. As of September 30, 2001 the
Company had not filed a registration statement to register these shares for
resale and $15,000 has been accrued in connection with this penalty fee.

     WARRANTS

     During the third quarter of 2001, the Company issued 81,250 warrants to
entities providing investment banking and other professional services to the
Company. These warrants were valued at approximately $48,000, which is being
amortized over the related period of services.

4.  NOTES AND CAPITAL LEASES PAYABLE

     On March 15, 2001, the Company entered into a Waiver and Second Amendment
to the Senior Credit Facility ("Waiver and Second Amendment") with its senior
lenders, Bank of America, LaSalle National Bank and Union Planters Bank, in
which they agreed to waive past defaults on its senior credit facility and the
Waiver and First Amendment. The Waiver and Second Amendment required that the
Company maintain its financial condition and operating profit within certain
defined parameters including ratios involving earnings before interest, taxes,
depreciation and amortization and interest expense. In addition, the Waiver and
Second Amendment contains a provision which requires the Senior Credit Facility
be refinanced or paid in full by April 2002.

     On March 30, 2001, the Company entered into an Amendment of the Master
Credit Facility with GE Capital to waive the tangible net worth covenant for the
4th Quarter 2000 and amended the covenant for each quarter in 2001.
Additionally, the Company has agreed to accelerate a portion of its principal
payments. At June 30, 2001, the Company was in compliance with the tangible net
worth covenant.

     On July 13, 2001, the Company entered into a Waiver and Third Amendment to
the Senior Credit Facility ("Waiver and Third Amendment") with its senior
lenders, the primary terms of which were as follows: (i) to extend the required
due date to refinance the Senior Credit Facility until July 1, 2002, (ii) extend
terms relative to the Company's borrowing base as defined in the Amendment and,
(iii) provide
                                        10

for mandatory prepayment when certain outstanding claims of the Company are
collected. The Company was in compliance with its covenants of the Senior Credit
Facility at June 30, 2001.

     On September 28, 2001, the Company notified all of the banks which
participate in its Senior Credit Facility that due to lower than expected sales
at the plastic lumber division the Company could not make the $2.5 million term
loan payment due September 30, 2001 without jeopardizing its business
operations. In addition, the Company is not in compliance with some of the
covenants under the Senior Credit Facility as of September 30, 2001. The Company
is currently in negotiations for a waiver of its covenant and payment defaults
and an amendment to the Senior Credit Facility whereby the lenders under the
facility would agree to accept interest only payments from the Company and allow
the Company to defer the September 30, and December 31, 2001 principal payments
until the earlier of February 28, 2002 or the sale of some of the Company's
assets. No assurance can be given as to whether or in what form this waiver will
be obtained.

     On October 4, 2001, the Company requested a suspension of principal
payments on its Master Credit Facility with GE Capital until the earlier of
March 31, 2002 or the sale of some of the Company's assets. Through November 14,
2001, the Company has continued to make all scheduled principal payments on its
Master Credit Facility but is continuing to negotiate the deferral of future
principal payments with GE Capital. As of September 30, 2001, the Company is not
in compliance with its tangible net worth covenant under the Master Credit
Facility. The Company is currently in negotiations with GE Capital to obtain a
waiver of the covenant default as of September 30, 2001. The Master Credit
Facility contains a provision whereby an event which would accelerate payment
terms of the Company's Senior Credit Facility would also accelerate the payment
terms of the Master Credit Facility to the same due date as the Senior Credit
Facility.

     The Company expects to finalize the waivers and amendments to the Senior
Credit Facility and the Master Credit Facility in the near future. While the
covenant violations and failure to make a principal payment do constitute an
event of default under the respective agreements, as of November 14, 2001
neither lending group has taken any action against the Company. The lending
groups have been negotiating forbearance agreements with the Company, and the
Company believes it will be successful in obtaining the necessary waivers and
forbearances from its lenders. However, in the event that waivers and a deferral
of principal are not obtained the lenders have the option of declaring the
Company in default and demand immediate repayment of the outstanding balances of
$38,800,000 and $11,899,000 of the Senior Credit Facility and Master Credit
Facility, respectively. All indebtedness outstanding at September 30, 2001 under
these credit facilities are reflected as current liabilities as of September 30,
2001 in the accompanying condensed consolidated balance sheets. The Company
currently does not have the financial resources to repay these debt obligations
in the event that they become immediately due without obtaining new debt and/or
equity capital and/or selling some of the Company's assets. Pursuant to the
terms of the Senior Credit Facility, upon the occurrence of an event of default,
the administrative agent for the lending banks, upon the request of the lending
banks, can declare all commitments terminated, and/or declare all Company loans
and other obligations due and payable.

5.  CONVERTIBLE SUBORDINATED DEBENTURES

     On February 20, 2001, the Company received a Put Notice from Halifax
relative to the 5% Convertible Subordinated Debenture issued on February 5, 2000
in the amount of $7,500,000 due February 5, 2005 (the "Fiscal 2000 Debenture").
Pursuant to the Put Notice, the Company had the option to either (a) repurchase
the outstanding principal amount plus all accrued, unpaid interest for a cash
price equal to 110% thereof, or (b) have the Minimum Floating Conversion Price
permanently re-set to zero. Prior to the Put Notice, the Minimum Floating
Conversion Price was $8.25 per share; however, since the stock price of the
Company's common stock had traded for less than $8.25 per share for ten
consecutive trading days ending February 16, 2001, Halifax Fund L.P. had this
right of re-set or buy-out. The Company did not elect to option (a) therefore
the Minimum Floating Conversion Price has permanently re-set to zero. The effect
of re-setting the Minimum Floating Conversion Price to zero is that upon
conversion of the Fiscal 2000 Debenture into common stock the price at which the
common stock of the Company will be issued to Halifax shall be equal to the
lowest trading price of the common stock on the principal trading market for
such common stock (which is currently the NASDAQ National Market) during the
four (4) trading days prior to but not including the holder's conversion date.

     In May 2001, $191,000 of the previously issued convertible subordinated
debentures and $1,000 of unpaid interest were converted into 189,800 shares of
common stock at an average conversion price of $1.02 per share. On June 22, 2001
an additional $2,000,000 of the previously issued convertible subordinated
debentures and $23,000 of unpaid interest were converted into 1,944,942 shares
of common stock at a conversion price of $1.04 per share. Unamortized debenture
issuance costs and debt discounts of $12,475 and $120,558 respectively were
charged to additional paid-in-capital. As a result of the above conversions, the
Company recorded an additional beneficial conversion feature benefit granted to
the holder of approximately $280,000, which was charged to interest expense
during the quarter ended June 30, 2001. As of September 30, 2001, $5,329,746,
net of discounts, is outstanding on the Fiscal 2000 convertible subordinated
debentures.

     On June 15, 2001, the Company issued a convertible subordinated debenture
due May 31, 2002 in the principal amount of $4.0 million (the "Fiscal 2001
Debenture") and a warrant to purchase 250,000 shares of its common stock, at an
initial purchase price of $2.00 per share, (the "Warrant") to Halifax. Halifax
paid the Company $4.0 million for these securities. The principal amount of the
Fiscal 2001 Debenture bears interest at a rate of 18% per year through August
14, 2001. On August 9, 2001, the Company and Halifax amended the Fiscal 2001
Debenture agreement to change the due date from May 31, 2002 to July 1, 2002.

                                        12

                   U.S. PLASTIC LUMBER CORP. AND SUBSIDIARIES

 NOTES TO CONDENSED UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The Company has the option at any time and, upon five business day's
notice, to repurchase all or any part of the Fiscal 2001 Debenture. At August
15, 2001, the Company did not repurchase the Fiscal 2001 Debenture, nor did it
consummate a sale/leaseback of some of its assets under the terms described in
the Fiscal 2001 Debenture Purchase Agreement. As a result, Halifax may convert
the principal amount plus accrued interest and any default payments on the
Fiscal 2001 Debenture into shares of the Company's common stock. The conversion
price of the common stock under the Fiscal 2001 Debenture is a price per share
equal to the average of the lowest trading prices of the common stock on the
principal trading market for the common stock during any three trading days
during the twenty-two trading days immediately prior to the conversion date.
Because the Fiscal 2001 Debenture was not repurchased by August 15, 2001 and the
sale/leaseback was not completed, in accordance with the terms of the Fiscal
2001 Debenture Purchase Agreement the Company: (i) issued to Halifax for no
consideration another Warrant to purchase 250,000 shares of its common stock at
a purchase price per share equal to 120% of the closing market price of such
stock on August 15, 2001, which was $0.90 per share and, (ii) increased the
coupon rate from 18% to 25%. On August 15, 2001, the Company recognized a
beneficial conversion feature in the amount of $534,000 which was recorded as a
discount to the debenture. The $170,000 value assigned to the warrants issued on
August 15, 2001 was recorded as an additional discount to the face value of the
debenture. These discounts are being accreted as interest expense through June
30, 2002. As of September 30, 2001 the outstanding balance on the Fiscal 2001
convertible debenture is $3,360,587, net of discounts.

     As part of the financing, the Company also granted a subordinate lien on
all its assets to Halifax through a Security Agreement. The lien not only
secures the Company's obligations under the Fiscal 2001 Debenture, but it also
secures the Company's obligations under the Fiscal 2000 Debenture due February
5, 2005 and the $1.0 million stated value of the Company's Series D Convertible
Preferred Stock previously sold to Halifax. In addition, the Fiscal 2001
Debenture Purchase Agreement with Halifax required that the shares and
associated warrants underlying the Fiscal 2001 Debenture be registered within 90
days of the June 15, 2001 closing date of the agreement. The Fiscal 2001
Debenture Purchase Agreement provides that the Company pay in cash a default
payment of 2.5% of the sum of the outstanding principal amount of the Fiscal
2001 Debenture plus the accrued interest for each thirty day period that the
shares are not registered. As of September 30, 2001 the Company had not filed a
registration to register these shares and the Company has accrued $50,000 in
penalties due Halifax as a result of the Company's failure to register these
shares.

6.  RESTRUCTURING CHARGES

     In September of 2001 the Company announced the closing of three of its
manufacturing facilities and the leasing of two of its resin processing plants
to third parties in an effort to reduce fixed costs, improve customer service
and narrow management's focus to a smaller number of manufacturing facilities,
without reducing total manufacturing capacity. The Fontana, California, Denton,
Maryland, and Trenton, Tennessee plants were closed on September 28, 2001 and
the equipment and manufacturing processes at these plants will be transferred to
the Chicago, Illinois and Ocala, Florida manufacturing locations. The Company is
currently attempting to obtain a buyout or sublease of the closed facilities. In
addition, the Company has discontinued raw material processing at its Auburn,
Massachusetts and Chino, California resin plants and has agreed to lease these
operations to other raw material processors. The Company will continue raw
material processing for its own use at the Chicago and Ocala plants.
Approximately 140 full time manufacturing and administrative positions were
eliminated in connection with the reduction in facilities. The plan of
restructure

was adopted by management and the board of directors and communicated to
employees in late September of 2001. As a result of this restructuring, the
Company recorded the following charges:

<Table>
<S>                                                           <C>
Write-down for equipment impairment.........................  $ 8,694,000
Write-down for goodwill impairment..........................    1,116,000
Lease termination, severance and other exit costs...........    1,656,000
                                                              -----------
  Total restructuring and asset impairment charges..........  $11,466,000
                                                              ===========
</Table>

During the third quarter, the Company paid approximately $196,000 in employee
termination and other expenses in connection with the restructuring and
approximately $1,460,000 remains in the accrual as of September 30, 2001,
primarily for lease termination expenses.

     In the fourth quarter of 2000, the Company committed to a plan to
restructure and to consolidate some of its smaller plants within the plastic
lumber division. Specifically, the Company closed its Reidsville, North Carolina
facility in the fourth quarter of 2000, its Green Bay, Wisconsin and Vernon,
California facilities in January 2001 and its Sweetser, Indiana facility early
in the third quarter of 2001. As a result, the Company recorded a charge of
$3,417,000 in the fourth quarter of 2000 for equipment impairment and lease
termination costs in connection with the restructuring. As of December 31, 2000,
the Company had accrued $1,098,000 in connection with the lease termination
costs and anticipates making lease termination payments throughout 2001 as it
completes its restructuring plan. During the nine months ended September 30,
2001, the Company paid approximately $457,000 in lease termination payments and
charged this amount against the accrual. As of September 30, 2001, the Company
has approximately $631,000 remaining in its restructuring accrual for lease
termination payments.

     During 2000 and early 2001, the Company eliminated approximately 300
employees as part of this restructuring plan. The severance component of the
restructuring plan was communicated to the employees in early January 2001. As a
result, the Company recorded a charge of approximately $182,000 during the three
months ended March 31, 2001 in connection with severance. During the nine months
ended September 30, 2001 the entire $182,000 was paid and no balance remains in
this accrual.

7.  LEGAL PROCEEDINGS

     In April 2001, the Company was served with an arbitration demand from
Southern Wood Services seeking an award of $3,328,000 due to the failure to
abide by the terms of a contract relative to the purchase of wood flour. On
September 12, 2001, the Company received a copy of an arbitration award in favor
of Southern Wood Services in the amount of $1,759,822, inclusive of arbitration
costs and expenses.

     The Company filed a motion to vacate the award based on the principle that
the award does not reflect any evidence presented at the hearing nor is the
award based on current case law on damages in similar cases in the United
States. The Company anticipates that it will be several months before a trial
court will hear the company's motion. Due to the fact that this is not a
judgement, the Company is not required to post a bond.

     The Company intends to vigorously contest this case and will appeal any
adverse ruling as it believes the law on damage awards in similar contracts in
the United States is clear and that arbitrators must base their decision on
existing legal authority. The Company cannot at this time predict the outcome of
the appeal or the amount of any liability, if any that would result in a
judgment by the courts.

8.  DERIVATIVES

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133.
In June 2000, the FASB issued SFAS No. 138, "Accounting for Certain Derivative
Instruments and Certain Hedging Activities, an

                                        14
<PAGE>
                   U.S. PLASTIC LUMBER CORP. AND SUBSIDIARIES

 NOTES TO CONDENSED UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Amendment of SFAS 133". SFAS No. 133 and SFAS No. 138 standardize the accounting
for derivative instruments, including certain derivative instruments embedded in
other contracts. Under the standards, entities are required to carry all
derivative instruments on the balance sheet at fair value. The accounting for
changes in the fair value (i.e., gains or losses) of a derivative instrument
depends on whether it has been designated and qualifies as part of a hedging
relationship and, if so, on the reason for holding it. If certain conditions are
met, entities may elect to designate a derivative instrument as a hedge of
exposures to changes in fair values, cash flows, or foreign currencies. If the
hedged exposure is a fair value exposure, the gain or loss on the derivative
instrument is recognized in earnings in the period of change, together with the
offsetting loss or gain on the hedged item attributable to the risk being
hedged. If the hedged exposure is a cash flow exposure, the effective portion of
the gain or loss on the derivative instrument is reported initially as a
component of other comprehensive income (outside earnings), and subsequently
reclassified into earnings when the forecasted transaction affects earnings. Any
amounts excluded from the assessment of hedge effectiveness, as well as the
ineffective portion of the gain or loss are reported in earnings immediately. If
the derivative instrument is not designated as a hedge, the gain or loss is
recognized in earnings in the period of change.

     As part of its overall interest rate risk management activities, the
Company utilizes interest rate related derivatives to manage its exposure to
various types of interest rate risks. The Company does not speculate using
derivative instruments.

     The Company's risk management policies emphasize the management of interest
rate risk within acceptable guidelines. The Company's objective in maintaining
these policies is to limit volatility arising from changes in interest rates.
Risks to be managed are primarily cash flow risks. Utilization of derivative
financial instruments provides a valuable tool to assist in the management of
these risks.

     The Company is exposed to interest rate cash flow risk due to loans under
its Senior Credit Facility whose interest payments are based on floating rate
indices. The Company continually monitors changes in these exposures and their
impact on its risk management activities. The Company has entered into interest
rate swap agreements under which the Company pays a fixed rate of interest and
receives a floating rate of interest over the term of the interest rate swap
agreement without the exchange of the underlying notional amounts. These
agreements allow the Company to offset the variability of floating rate loan
interest with the variable interest payments due on the interest rate swaps. The
Company assesses the effectiveness of these hedges by comparing the timing,
frequency, and magnitude of changes in its interest rate to that of the interest
rate referenced in the swap agreements.

     Under SFAS No. 133 and SFAS No. 138, changes in the fair value of interest
rate swaps designated as hedges of the variability of cash flows associated with
floating rate debt are reported in other comprehensive income. These amounts are
subsequently reclassified into interest income as a yield adjustment of the
hedged loans.

     The Company adopted SFAS No. 133 and SFAS No. 138 on January 1, 2001. In
accordance with the transition provisions of SFAS No. 133, the Company recorded
a net-of-tax cumulative-effect loss of $453,615 in accumulated other
comprehensive income to recognize at fair value two interest-rate swap
derivatives that are designated as a cash-flow hedging instruments. As of
September 30, 2001, the net-of-tax fair value of these derivatives carried as a
component of other comprehensive loss was $1,123,891.

10.  RECENT ACCOUNTING PRONOUNCEMENTS

     In July 2001, the Financial Accounting Standards Board ("FASB") issued
Statement No. 141, Business Combinations ("SFAS No. 141"), and Statement No.
142, Goodwill and Other Intangible Assets ("SFAS No. 142"). SFAS No. 141
requires that the purchase method of accounting be used for all business
combinations initiated after June 30, 2001 as well as all purchase method
business combinations completed after June 30, 2001. SFAS No. 141 also specifies
criteria intangible assets acquired in a purchase method business combination
must meet to be recognized and reported apart from goodwill, noting that any
purchase price allocable to an assembled workforce may not be accounted for
separately. SFAS No. 142 will require that goodwill and intangible assets with
indefinite useful lives no longer be amortized, but instead tested for
impairment at least annually in accordance with the provisions of SFAS No. 142.
SFAS No. 142 will also require that intangible assets with definite useful lives
be amortized over their respective estimated useful lives to their estimated
residual values, and reviewed for impairment in accordance with SFAS No. 121,
Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of.

     The Company is required to adopt the provisions of SFAS No. 141 immediately
and SFAS No. 142 effective January 1, 2002. Goodwill and intangible assets
acquired in business combinations completed before July 1, 2001 will continue to
be amortized prior to the adoption of SFAS No. 142.

     SFAS No. 141 will require upon adoption of SFAS No. 142 that the Company
evaluate its existing intangible assets and goodwill that were acquired in a
prior purchase business combination, and to make any necessary reclassifications
in order to conform with the new criteria in SFAS No. 141 for recognition apart
from goodwill. Upon adoption of SFAS No. 142, the Company will be required to
reassess the useful lives and residual values of all intangible assets acquired
in purchase business combinations, and make any necessary amortization period
adjustments by the end of the first interim period after adoption. In addition,
to the extent an intangible asset is identified as having an indefinite useful
life, the Company will be required to test the intangible asset for impairment
in accordance with the provisions of SFAS No. 142 within the first interim
period. Any impairment loss will be measured as of the date of adoption and
recognized as the cumulative effect of a change in accounting principle in the
first interim period.

     In connection with the transitional goodwill impairment evaluation, SFAS
No. 142 will require the Company to perform an assessment of whether there is an
indication that goodwill is impaired as of the date of adoption. To accomplish
this, the Company must identify its reporting units and determine the carrying
value of each reporting unit by assigning the assets and liabilities, including
the existing goodwill and intangible assets, to those reporting units as of the
date of adoption. The Company will then have up to six months from the date of
adoption to determine the fair value of each reporting unit and compare it to
the reporting unit's carrying amount. To the extent a reporting unit's carrying
amount exceeds its fair value, an indication exists that the reporting unit's
goodwill may be impaired and the Company must perform the second step of the
transitional impairment test. In the second step, the Company must compare the
implied fair value to all of its

                                        16

assets (recognized and unrecognized) and liabilities in a manner similar to a
purchase price allocation in accordance with SFAS No. 141, to its carrying
amount, both of which would be measured as of the date of adoption. Any
transitional impairment loss will be recognized as the cumulative effect of a
change in accounting principle in the Company's statement of operations.

     As of the date of adoption, the Company expects to have unamortized
goodwill in the amount of approximately $25,283,000, and an unamortized permit
in the amount of $9,344,000, which will be subject to the transition provisions
of SFAS No. 141 and 142. Amortization expense related to goodwill and the permit
was approximately $1,665,000 and $1,090,000 for the year ended December 31, 2000
and nine months ended September 30, 2001, respectively.

     Because of the extensive effort needed to comply with adopting Statements
141 and 142, it is not practicable to reasonably estimate the impact of adopting
these Statements on the Company's financial statements at the date of this
report, including whether any transitional impairment losses will be required to
be recognized as the cumulative effect of a change in accounting principle.

     Also, in July the FASB issued Statement No. 143 ("SFAS No. 143"),
Accounting for Asset Retirement Obligations ("SFAS No. 143"). That standard
requires entities to record the fair value of a liability for an asset
retirement obligation in the period in which it is incurred. When the liability
is initially recorded, the entity will capitalize a cost by increasing the
carrying amount of the related long-lived asset. Over time, the liability is
accreted to its present value each period, and the capitalized cost is
depreciated over the useful life of the related asset. Upon settlement of the
liability, an entity either settles the obligation for its recorded amount or
incurs a gain or loss upon settlement. The standard is effective for fiscal
years beginning after June 15, 2002, with earlier adoption permitted. Due to the
extensive effort needed to comply with adopting SFAS No. 143, it is not
practicable to reasonably estimate the impact of adopting this statement as of
the date of this report.

     On October 3, 2001, the FASB issued Statement No. 144, Accounting for the
Impairment or Disposal of Long-Lived Assets, ("SFAS No 144") which addresses
financial accounting and reporting for the impairment or disposal of long-lived
assets. While Statement No. 144 supersedes FASB Statement No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of, it retains many of the fundamental provisions of that Statement. Statement
No. 144 also supersedes the accounting and reporting provisions of APB Opinion
No. 30, Reporting the Results of Operations -- Reporting the Effects of Disposal
of a Segment of a Business, and Extraordinary, Unusual and Infrequently
Occurring Events and Transactions, for the disposal of a segment of a business.
However, it retains the requirement in Opinion No. 30 to report separately
discontinued operations and extends that reporting to a component of an entity
that either has been disposed of (by sale, abandonment, or in a distribution to
owners) or is classified as held for sale. The provisions of SFAS No. 144 become
effective for fiscal years beginning after December 15, 2001 and must be adopted
as of the beginning of a fiscal year. Early adoption is encouraged but not
required. Due to the extensive effort needed to comply with adopting SFAS No.
144, it is not practicable to reasonably estimate the impact of adopting this
statement as of the date of this report.

11.  SEGMENT REPORTING

     The Company has two reportable operating segments. The Plastic lumber
division manufactures structural and non-structural plastic lumber and a variety
of accessory products such as park and site amenities. The Environmental
recycling division provides environmental recycling services including
environmental construction services, upland disposal of dredge materials,
beneficial re-use of industrial wastes and on-site recycling services. In the
third quarter of 2001, the Plastic lumber division recorded restructuring and
asset impairment charges of $11,466,000. In the first quarter of 2001 the
Plastic lumber division recorded a

                   U.S. PLASTIC LUMBER CORP. AND SUBSIDIARIES

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

LIQUIDITY AND CAPITAL RESOURCES

     Cash and cash equivalents totaled $1,035,000 at September 30, 2001, a
decrease of $1,176,000 from the $2,211,000 at December 31, 2000. Cash provided
by operating activities amounted to $1,867,000 for the first nine months of 2001
while cash used in operating activities for the comparable period in 2000
amounted to $11,285,000. The change is primarily due to decreases in receivable
and inventory balances of $1,428,000 and $2,219,000 respectively in 2001,
compared to increases in receivables and inventories of $16,072,000 and
$3,595,000 respectively in 2000, partially offset by a smaller increase in
payables and lower earnings in the 2001 period as compared to 2000.

     Cash used in investing activities was $2,314,000 in the first nine months
of 2001, a decrease of $17,963,000 from the prior year. The decrease is
primarily due to a significant reduction in capital expenditures at the Plastic
lumber division, whose major capital expansion was completed during 2000.

     Cash used in financing activities totaled $730,000 for the nine months
ending September 30, 2001. During this period, $3,732,000 in net proceeds from
the sale of an 18% convertible debenture, $999,000 in net proceeds from the
issuance of convertible preferred stock, $983,000 in net proceeds from the sale
of common stock, and $1,200,000 in additional borrowings under existing credit
agreements were offset by $7,652,000 of principal payments on existing notes and
capital leases payable, including net repayments of $3,600,000 on the Senior
Credit Facility.

     At September 30, 2001, the Company's current liabilities exceeded current
assets by $49,368,000, compared to net working capital of $10,965,000 at
December 31, 2000. The change is due primarily to the entire Senior Credit
facility of $38,800,000 maturing in less than one year as of September 30, 2001,
as compared to $7,500,000 as of December 31, 2000, and to convertible
subordinated debentures, net of discounts, of $3,361,000 and $4,956,000 due to
Halifax and the Stout Partnership respectively maturing on July 1, 2002. The
Stout Partnership is the Company's largest shareholder. Several members of the
Company's Board of Directors and a member of management are affiliated with the
Stout Partnership. In addition, certain cross-default provisions contained in
the Master Credit Facility with GE Capital require the classification of the
entire Master Credit Facility of $11,899,000 as current portion of long term
debt. In addition, the Company is currently not in compliance with the tangible
net worth covenant of the Master Credit Facility as of September 30, 2001. The
remainder of the difference is due to increases in accounts payable and accrued
expenses and decreases in inventory and accounts receivable.

     Capital expenditures in the first nine months of 2001 amounted to
$2,578,000, a decrease of $18,171,000 over the same period in 2000. The decrease
is primarily due to the completion of the Plastic lumber division's major
capital expansion during 2000. Capital expenditures in 2001 consisted primarily
of $1,363,000 to expand capacity at the Environmental recycling division and
$1,212,000 for purchases of manufacturing equipment for the Plastic lumber
division. Capital expenditures for the remainder of 2001 are expected to be
approximately $1,250,000.

     On September 28, 2001, the Company notified all of the banks which
participate in its Senior Credit Facility that due to lower than expected sales
at the plastic lumber division the Company could not make the $2.5 million term
loan payment due September 30, 2001 without jeopardizing its business
operations. In addition, the Company is not in compliance with some of its
covenants under the Senior Credit Facility as of September 30, 2001. The Company
is currently in negotiations for a waiver of its covenant violations and failure
to make the scheduled principal payment, as well as an amendment to the Senior
Credit Facility whereby the lenders under the facility would agree to accept
interest only payments from the Company and allow the Company to defer the
September 30, and December 31, 2001 principal payments until the earlier of
February 28, 2002 or the sale of some of the Company's assets. No assurance can
be given as to whether or in what form this waiver will be obtained.

                                        19
<PAGE>

     On October 4, 2001, the Company requested a suspension of principal
payments on its Master Credit Facility with GE Capital until the earlier of
March 31, 2002 or the sale of some of the Company's assets. Through November 14,
2001, the Company has continued to make all scheduled principal payments on its
Master Credit Facility but is continuing to negotiate the deferral of future
principal payments with GE Capital. As of September 30, 2001, the Company is not
in compliance with its tangible net worth covenant under the Master Credit
Facility. The Company is currently in negotiations with GE Capital to obtain a
waiver for this covenant violation as of September 30, 2001. The Master Credit
Facility contains a provision whereby an event which would accelerate payment
terms of the Company's Senior Credit Facility would also accelerate the payment
terms of the Master Credit Facility to the same due date as the Senior Credit
Facility.

     The Company expects to finalize the waivers and amendments to the Senior
Credit Facility and the Master Credit Facility in the near future. While the
covenant violations and failure to make a principal payment do constitute events
of default under the respective agreements, as of November 14, 2001 neither
lending group has taken any action against the Company. The lending groups have
been negotiating forbearance agreements with the Company, and the Company
believes it will be successful in obtaining the necessary waivers and
forbearances from its lenders. However, in the event that waivers and a deferral
of principal are not obtained the lenders have the option of declaring the
Company in default and demand immediate repayment of the outstanding balances of
$38,800,000 and $11,899,000 of the Senior Credit Facility and Master Credit
Facility, respectively. The Company currently does not have the financial
resources to repay these debt obligations in the event that they become
immediately due without obtaining new debt and/or equity capital and/or selling
some of the Company's assets. Pursuant to the terms of the Senior Credit
Facility, upon the occurrence of an event of default, the administrative agent
for the lending banks, upon the request of the lending banks, can declare all
commitments terminated, and/or declare all Company loans and other obligations
due and payable.

     The Company's liquidity and ability to meet its financial obligations will
be dependent on among other things, the Company's ability to obtain waivers for
its debt covenant and payment violations as of September 30, 2001 and through
the date of this filing, maintain compliance with future debt covenants and
raise new capital through the issuance of additional equity, new debt financing
and/or sell some of the Company's assets.

     The Company is highly leveraged and during 2000 and the nine months ended
September 30, 2001, the Company suffered significant losses from operations,
primarily resulting from the expenses incurred in its plastic lumber division
related to the expansion and start up of certain manufacturing facilities, the
inefficiencies in the production of certain products, increases in raw material
costs and interest expense. During the third quarter of 2001 the Company closed
three of its plastic lumber manufacturing facilities and agreed to sub-lease two
of its resin processing plants to third party raw material processors. In
connection with the exiting of these facilities, the Company eliminated
approximately 140 full time manufacturing positions, recorded asset impairment
charges of $9,810,000 and recorded a restructuring charge of $1,656,000 (see
Note 6). The Company's accumulated deficit totaled approximately $33,932,000 as
of September 30, 2001.

     Since its inception, the Company has financed its operations through a
number of stock and debt issuances. During 2000 and the first nine months of
2001, the Company's primary sources of working capital have been the net
proceeds from sales of the Company's convertible preferred and common stock,
proceeds from its Senior Credit Facility, the issuance of convertible
subordinated debentures and direct sales of the Company's products and services
to its customers. As of December 31, 2000, the Company was not in compliance
with certain covenant requirements of its Senior Credit Facility and its Master
Credit Facility. The Company received waivers for these covenant violations as
of December 31, 2000 and entered into amendments to the Senior Credit Facility
and Master Credit Facility (see Note 4).

     The Company's material financial commitments relate principally to its
working capital requirements and obligations to make term loan payments on its
Senior Credit Facility. As of September 30, 2001, the outstanding balance on the
Senior Credit Facility is $38,800,000. Under the terms of the proposed amended
Senior Credit Facility, the $2.5 million principal payments due September 30,
and December 31, 2001 would be deferred until February 28, 2002 or the sale of
some of the Company's assets. Additional principal

                                        20
<PAGE>

payments in the amount of $2.5 million each are due on March 31, and June 30,
2002. The remaining outstanding balance would have to be refinanced or repaid on
or before July 2, 2002. On or before July 1, 2002, the Company is also required
to retire its $4,000,000 convertible debenture issued to the Halifax Fund, L.P.
("Halifax"), as well as its $5,000,000 convertible debenture payable to the
Stout Partnership. Several members of the Company's Board of Directors and a
member of management are affiliated with the Stout Partnership. The Company
currently does not have the financial resources to retire these debt obligations
in 2002 and the Company will need to obtain new debt and/or equity capital
and/or sell certain assets to meet these requirements.

     Additional financial obligations of the Company include interest payments
on the Senior Credit Facility of approximately $275,000 per month, lease
payments pursuant to certain real property and equipment leases of approximately
$203,000 per month, installment payments for manufacturing equipment of
approximately $240,000 per month commencing March 31, 2002, interest payments on
the Company's Convertible Subordinated Debentures of approximately $460,000
quarterly, and dividends on the Company's Series D and Series E Convertible
Preferred Stock of approximately $231,000 quarterly. As of September 30, 2001
the Company has not made any dividend payments on its Series D Convertible
Preferred Stock. Dividends in arrears pertaining to the Series D Convertible
Preferred Stock amount to $652,000 at September 30, 2001. There are no dividends
in arrears with respect to the Series E Convertible Preferred Stock.

     The terms of the Senior Credit Facility also required the Company to raise
$6,500,000 of equity or equity equivalents by February 28, 2002. During February
and March 2001, the Company raised $1 million through the issuance of its Series
"E" Convertible Preferred Stock. In June 2001, the Company raised $4 million
through the issuance of a subordinated convertible debenture, due July 1, 2002.
Additionally, on July 3, 2001, the Company raised $1 million through the
issuance of 952,381 shares of common stock. This private placement transaction
was not registered under the Securities and Exchange Act of 1934 (the "Act") in
reliance upon the exemption from registration in Section 4(2) of the Act, as a
transaction not involving any public offering. The offering was completed
without any general or public solicitation to a very limited number of entities
with strong knowledge and experience in business and financial matters. Their
knowledge and experience enabled them to evaluate the risks and merits of the
investment. On November 1, 2001 the Company raised an additional $800,000
through the issuance of 1,334,000 shares of common stock in a private placement
with reliance upon the exemption from registration similar to that of the July
3rd private placement. With the completion of this transaction, the Company has
now met the financial covenant contained in the Senior Credit Facility
pertaining to the securing of equity or equity equivalents. However, the Company
will also need to raise additional capital by selling certain assets and/or
obtaining additional sources of debt and/or equity in order to meet its
financial obligations.

     Some of the Company's debt instruments contain covenants establishing
performance measurement through various financial ratios and operating
restrictions. The Company's failure to comply with any covenant or material
obligation contained in these debt agreements or any of the Company's other debt
agreements, absent a waiver from the lenders, would result in an event of
default which could accelerate debt repayment terms under the debt agreements.
Due to various cross-default provisions contained within some of the Company's
credit agreements, an event of default under the senior debt agreements could
accelerate debt repayment terms under some of the other credit agreements, all
of which would have a material adverse affect on the Company's liquidity and
capital resources..

     Capital requirements relating to the implementation of the Company's
business plan have been and will continue to be significant. The Company
believes that its ability to generate cash from operations is dependent upon,
among other things, increased demand for its products and services and the
successful development of direct marketing, improved manufacturing efficiencies
and product distribution capabilities. There can be no assurance that the
Company will have sufficient capital resources to permit the Company to continue
implementation of its business plan.

     In November of 2000, the Company retained Bank of America Securities to
explore and evaluate strategic alternatives for the Company, which could include
the possible sale of the Company's environmental recycling division, Clean Earth
Inc. ("CEI"). No agreement has been reached with any prospective buyers

                                        21

and there can be no assurances that an agreement will be reached Proceeds from
the sale of CEI, if it occurs, would be used to first pay down the Company's
Senior Credit Facility. Any excess proceeds would be applied to some the
Company's other debt obligations and provide working capital.

     While there can be no assurances, the Company believes its cash flows from
operations, the sale of certain assets, and/or the raising of additional capital
will satisfy its liquidity requirements through September 30, 2002. The Company
is seeking additional sources of financing to supplement its cash flow
requirements, however, there can be no assurance that any additional financing
will be available to the Company on acceptable terms, or at all. If the Company
does not obtain the necessary waivers and amendments from the lending groups for
covenant violations and failure to make the scheduled principal payment as of
September 30, 2001, comply in the future with the covenants contained within its
debt agreements, or if adequate cash flow from operations, funds from the
capital markets or proceeds from the sale of assets are not available to finance
the Company's operations and retire its debt obligations as they become due, the
Company will be required to significantly curtail its operations and the
Company's ability to continue as a going concern would be impaired.

     On September of 2001, the Company was advised by the Staff of Nasdaq
National Market that the Company's stock failed to maintain a minimum bid price
of $1.00 over the previous 30 consecutive trading days, and that in accordance
with the Nasdaq Market Place Rules, the Company had 90 calendar days, or until
December 5, 2001, to regain compliance. On September 28, 2001 the Company
received notification from Nasdaq that the listing qualification notice
previously received had been suspended until January 2, 2002. If the bid price
for the Company's common stock is not above $1.00 per share for at least 10
consecutive trading days prior to April 2, 2002, or if the Company fails to
comply with any other requirement for continued listing, the Company's common
stock will be delisted from trading on the Nasdaq National Market, subject to
the Company's right to appeal. If the Company's stock were to be delisted, it
may adversely impact the Company's ability to secure additional equity
financing.

INTERIM RESULTS OF OPERATIONS

     COMPARISON OF THE THREE MONTHS ENDED SEPTEMBER 30, 2001 AND 2000

     Net sales in the third quarter of 2001 were $46,823,000, a decrease of
$3,265,000, or 6.5%, as compared to the third quarter of 2000. Plastic lumber
division revenues decreased by 21.5% in the quarter to $15,323,000, as a result
of the Company's decision to exit the lower margin resin business. Environmental
recycling division revenues increased by 3% to $31,500,000 in the second quarter
of 2001.

     Gross profit in the third quarter 2001 increased by $495,000, or 8%, as
compared to the third quarter of 2000. The increase was primarily due to product
returns and associated inventory write-downs in the Plastic lumber division
during the third quarter of 2000. Gross profit margin as a percent of revenues
in the Plastic lumber division increased in the third quarter of 2001 to 9.7%,
as compared to 2.1% in the third quarter of 2000. Gross profit at the
Environmental recycling division decreased by $586,000, or 10.3%, to $5,122,000
versus the same quarter in 2000. The Environmental recycling division's gross
profit as a percent of revenue decreased to 16.3% in 2001 from 18.7% in 2000,
due primarily to a shift in revenue mix to the dredging and construction
services group, whose revenues traditionally have lower margins.

     Selling, general and administrative expenses ("SG&A), excluding
restructuring and asset impairment charges of $11,466,000, remained flat in the
third quarter of 2001, as increases in legal and insurance expenses were largely
offset by cost reduction efforts at both the Plastic lumber and Environmental
recycling divisions. As a percentage of net sales, SG&A increased to 16.7% in
the three months ended September 30, 2001 as compared to 15.6% in the three
months ended September 30, 2000, mainly due to lower sales.

     The third quarter of 2001 produced an operating loss of $12,669,000 as
compared to $1,692,000 for the same quarter in 2000. Excluding the restructuring
and asset impairment charges in 2001, operating loss was $1,204,000. Operating
income decreased by $517,000 at the Environmental recycling division due to
lower gross margins. Operating loss at the Plastic lumber division, excluding
restructuring and asset impairment

                                        22
<PAGE>

charges, improved by $1,522,000 as compared with the same quarter in 2000 due to
higher gross margins and reduced SG&A expenses.

     Interest expense increased by $1,109,000 for the third quarter of 2001,
mainly due to higher interest rates incurred by the Company in 2001 and
increased amortization of debt discounts and deferred financing costs as
compared to 2000, partially offset by lower debt levels.

     Income tax expense in the third quarter of 2001 was $710,000 as compared to
income tax benefit of $1,101,000 in the third quarter of 2000, as the Company
concluded in the current quarter that it was more likely than not that the
Company would fail to generate sufficient future taxable income to utilize all
of its deferred tax assets.

     COMPARISON OF THE NINE MONTHS ENDED SEPTEMBER 30, 2001 AND 2000

     Net sales for the first nine months of 2001 were $136,210,000, an increase
of $11,458,000, or 9.2%, over the same period of 2000. Plastic lumber division
revenues decreased by 17% in the period to $47,533,000, as a result of the
Company's decision to exit the lower margin resin business. Environmental
recycling division revenues increased by 35.4% to $88,677,000 due to an increase
in major projects in the dredging and construction services group, as compared
to the same period in 2000.

     Gross profit in the first nine months of 2001 decreased by $3,075,000, or
14.4%, compared with the first nine months of 2000. The decrease was primarily
due to lower revenue and underabsorption of manufacturing overhead costs at the
Plastic lumber division. Gross profit margin as a percent of revenues in the
Plastic lumber division decreased from 15.1% in the first nine months of 2000 to
10.1% in the first nine months of 2001. Gross profit margin at the Environmental
recycling division decreased to 15.1% in 2001 from 18.8% in 2000 primarily due
to the increase in the lower margin project work. Gross profit at the
Environmental recycling division increased by $1,078,000, or 8.9%, due to the
overall increased revenue volume in the first nine months of 2001.

     SG&A expenses, excluding restructuring and asset impairment charges,
increased by $749,000 in the first nine months of 2001, primarily due to
increases in marketing expenses in the Plastic lumber division and support for
the higher revenue experienced at the Environmental recycling division. As a
percentage of net sales, SG&A, excluding restructuring and asset impairment
charges, decreased to 14.4% in 2001 from 17.0% in 2000, primarily due to
increased sales volume at the Environmental recycling division.

     The first nine months of 2001 produced an operating loss of $13,049,000, as
compared to operating income of $2,424,000 for the same period in 2000.
Excluding the asset impairment and restructuring charges, operating loss in 2001
would have been $1,401,000, primarily due to the decline in revenue and gross
margins in the Plastic lumber division. Operating income increased by $458,000
at the Environmental recycling division, while operating loss at the Plastic
lumber division increased by $3,394,000 to $4,593,000, excluding the
restructuring and asset impairment charges of $11,648,000.

     Interest expense increased by $3,943,000 for the first nine months of 2001,
mainly due to higher interest rates incurred by the Company in 2001 and
increased amortization of debt discounts and deferred financing costs as
compared to 2000, partially offset by lower debt levels.

SEASONALITY

     The Company experiences a seasonal slow down during the winter months
because its environmental operations are located in the Northeast United States
where adverse weather and normal ground freezing can impact the Company's
performance. Additionally, sales of certain plastic lumber products slow
significantly in the winter months.

RECENTLY ISSUED ACCOUNTING STANDARDS

     In July 2001, the FASB issued Statement No. 141, Business Combinations
("SFAS No. 141"), and Statement No. 142, Goodwill and Other Intangible Assets
("SFAS No. 142"). SFAS No. 141 requires that

                                        23
<PAGE>

the purchase method of accounting be used for all business combinations
initiated after June 30, 2001 as well as all purchase method business
combinations completed after June 30, 2001. SFAS No. 141 also specifies criteria
intangible assets acquired in a purchase method business combination must meet
to be recognized and reported apart from goodwill, noting that any purchase
price allocable to an assembled workforce may not be accounted for separately.
SFAS No. 142 will require that goodwill and intangible assets with indefinite
useful lives no longer be amortized, but instead tested for impairment at least
annually in accordance with the provisions of SFAS No. 142. SFAS No. 142 will
also require that intangible assets with definite useful lives be amortized over
their respective estimated useful lives to their estimated residual values, and
reviewed for impairment in accordance with SFAS No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of.

     The Company is required to adopt the provisions of SFAS No. 141 immediately
and SFAS No. 142 effective January 1, 2002. Goodwill and intangible assets
acquired in business combinations completed before July 1, 2001 will continue to
be amortized prior to the adoption of SFAS No. 142.

     SFAS No. 141 will require upon adoption of SFAS No. 142 that the Company
evaluate its existing intangible assets and goodwill that were acquired in a
prior purchase business combination, and to make any necessary reclassifications
in order to conform with the new criteria in SFAS No. 141 for recognition apart
from goodwill. Upon adoption of SFAS No. 142, the Company will be required to
reassess the useful lives and residual values of all intangible assets acquired
in purchase business combinations, and make any necessary amortization period
adjustments by the end of the first interim period after adoption. In addition,
to the extent an intangible asset is identified as having an indefinite useful
life, the Company will be required to test the intangible asset for impairment
in accordance with the provisions of SFAS No. 142 within the first interim
period. Any impairment loss will be measured as of the date of adoption and
recognized as the cumulative effect of a change in accounting principle in the
first interim period.

     In connection with the transitional goodwill impairment evaluation, SFAS
No. 142 will require the Company to perform an assessment of whether there is an
indication that goodwill is impaired as of the date of adoption. To accomplish
this, the Company must identify its reporting units and determine the carrying
value of each reporting unit by assigning the assets and liabilities, including
the existing goodwill and intangible assets, to those reporting units as of the
date of adoption. The Company will then have up to six months from the date of
adoption to determine the fair value of each reporting unit and compare it to
the reporting unit's carrying amount. To the extent a reporting unit's carrying
amount exceeds its fair value, an indication exists that the reporting unit's
goodwill may be impaired and the Company must perform the second step of the
transitional impairment test. In the second step, the Company must compare the
implied fair value to all of its assets (recognized and unrecognized) and
liabilities in a manner similar to a purchase price allocation in accordance
with SFAS No. 141, to its carrying amount, both of which would be measured as of
the date of adoption. This second step is required to be completed as soon as
possible, but no later than the end of the year of adoption. Any transitional
impairment loss will be recognized as the cumulative effect of a change in
accounting principle in the Company's statement of operations.

     As of the date of adoption, the Company expects to have unamortized
goodwill in the amount of approximately $25,283,000, and an unamortized permit
in the amount of $9,344,000, which will be subject to the transition provisions
of SFAS No. 141 and 142. Amortization expense related to goodwill and the permit
was approximately $1,665,000 and $1,090,000 for the year ended December 31, 2000
and nine months ended September 30, 2001, respectively.

     Because of the extensive effort needed to comply with adopting Statements
141 and 142, it is not practicable to reasonably estimate the impact of adopting
these Statements on the Company's financial statements at the date of this
report, including whether any transitional impairment losses will be required to
be recognized as the cumulative effect of a change in accounting principle.

     Also, in July the FASB issued Statement No. 143 ("SFAS No. 143"),
Accounting for Asset Retirement Obligations ("SFAS No. 143"). That standard
requires entities to record the fair value of a liability for an asset
retirement obligation in the period in which it is incurred. When the liability
is initially recorded, the entity will capitalize a cost by increasing the
carrying amount of the related long-lived asset. Over time, the
                                        24
<PAGE>

liability is accreted to its present value each period, and the capitalized cost
is depreciated over the useful life of the related asset. Upon settlement of the
liability, an entity either settles the obligation for its recorded amount or
incurs a gain or loss upon settlement. The standard is effective for fiscal
years beginning after June 15, 2002, with earlier adoption permitted. Due to the
extensive effort needed to comply with adopting SFAS No. 143, it is not
practicable to reasonably estimate the impact of adopting this statement as of
the date of this report.

     On October 3, 2001, the FASB issued Statement No. 144, Accounting for the
Impairment or Disposal of Long-Lived Assets, ("SFAS No. 144") which addresses
financial accounting and reporting for the impairment or disposal of long-lived
assets. While Statement No. 144 supersedes FASB Statement No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of, it retains many of the fundamental provisions of that Statement. Statement
No. 144 also supersedes the accounting and reporting provisions of APB Opinion
No. 30, Reporting the Results of Operations -- Reporting the Effects of Disposal
of a Segment of a Business, and Extraordinary, Unusual and Infrequently
Occurring Events and Transactions, for the disposal of a segment of a business.
However, it retains the requirement in Opinion No. 30 to report separately
discontinued operations and extends that reporting to a component of an entity
that either has been disposed of (by sale, abandonment, or in a distribution to
owners) or is classified as held for sale. The provisions of SFAS No. 144 become
effective for fiscal years beginning after December 15, 2001 and must be adopted
as of the beginning of a fiscal year. Early adoption is encouraged but not
required. Due to the extensive effort needed to comply with adopting SFAS No.
144, it is not practicable to reasonably estimate the impact of adopting this
statement as of the date of this report.

                           PART II. OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

     In April 2001, the Company was served with an arbitration demand from
Southern Wood Services seeking an award of $3,328,000 due to the failure to
abide by the terms of a contract relative to the purchase of wood flour. The
Company utilizes wood flour for the production of its SmartDeck composite
product. The arbitration hearing took place in the first week of August 2001 in
Atlanta, Georgia in accordance with the rules and procedures of the American
Arbitration Association. On September 12, 2001 the Company received a copy of an
arbitration award in favor of Southern Wood Services in the amount of
$1,759,822, inclusive of arbitration costs and expenses.

     The Company filed a motion to vacate the award based on the principle that
the award does not reflect any evidence presented at the hearing nor is the
award based on current case law on damages in similar cases in the United
States. The Company anticipates that it will be several months before a trial
court will hear the company's motion. Due to the fact that this is not a
judgement, the Company is not required to post a bond.

     The Company intends to vigorously contest this case and will appeal any
adverse ruling as it believes the law on damage awards in similar contracts in
the United States is clear and that arbitrators must base their decision on
existing legal authority. The Company cannot at this time predict the outcome of
the appeal or the amount of any liability, if any that would result in a
judgment by the courts.

     From time to time, the Company is involved as plaintiff or defendant in
various legal proceedings arising in the normal course of its business. While
the ultimate outcome of these various legal proceedings cannot be predicted with
certainty, it is the opinion of management that the resolution of these legal
actions should not have a material effect on the Company's financial position,
results of operations or liquidity.

ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS

     Issuances of Common Stock in private offerings during the three months
ended September 30, 2001 are listed in the following paragraphs.

     On July 3, 2001, the Company issued 476,191 shares of common stock to ZLP
Master Fund, LTD. and 476,190 shares of common stock to ZLP Master Technology
Fund, LTD. at a purchase price of $1.05 per share. This private placement
transaction was not registered under the Act in reliance upon the exemption from
registration in Section 4(2) of the Act, as transaction not involving any public
offering. The offering was completed without any general or public solicitation
to a very limited number of entities who have strong knowledge and experience in
business and financial matters. Their knowledge and experience enabled them to
evaluate the risks and merits of the investment. The Company also issued 35,000
shares as compensation for professional services in connection with this
transaction.

     During the third quarter of 2001, the Company issued 100,000 warrants to
purchase shares of the Company's common stock to Fusion Capital in exchange for
Fusion Capital's agreement to amend the common stock purchase agreement between
Fusion Capital and the Company. Also during the third quarter of 2001, the
Company issued 81,250 warrants to entities providing investment banking and
other professional services to the Company.
