                               SECURITY AGREEMENT

         Security Agreement, dated as of June 15, 2001, made by and among U.S.
Plastic Lumber Corp., a Nevada corporation with principal offices at 2300 Glades
Road, Suite 440 West, Boca Raton, Florida 33431 (the "Company"), each of the
undersigned wholly-owned subsidiaries ("Subsidiaries") of the Company with
principal offices at the addresses specified by their respective signatures and
Halifax Fund, L.P., a limited partnership with offices at 195 Maplewood Avenue,
Maplewood, New Jersey 07040 ("Purchaser"). The Company and the Subsidiaries are
sometimes hereinafter referred to as the "Grantors". Purchaser is sometimes
hereafter referred to as the "Secured Party."

         WHEREAS, the parties hereto are entering into the Debenture Purchase
Agreement (the "Debenture Purchase Agreement") of even date herewith, pursuant
to which the Company will sell and issue to Purchaser certain 18% Debentures
(the "Debentures") in the aggregate principal amount of $4,000,000;

         WHEREAS, Section 4.2(g) of the Debenture Purchase Agreement provides
that a condition precedent to Purchaser's obligation to purchase the Debentures
is the execution and delivery by the Grantors of this Security Agreement
granting Purchaser a subordinate lien on all assets of the Grantors for the
purpose of securing the Company's obligations (i) under the Debentures, (ii)
under the Company's outstanding 5% convertible debentures due February 2, 2005
(the "2000 Debentures") and (iii) under the Company's Series D 15% Preferred
Stock, (the "Series D Preferred Stock").

         NOW THEREFORE, in consideration of the foregoing, each of the Grantors
hereby respectively agrees with the Secured Party as follows:

                  SECTION 1.        Grant of Security Interest. As collateral
security for all of the Obligations (as defined in Section 2 hereof), each of
the Grantors hereby respectively pledge and collaterally assign to the Secured
Party, and grant to the Secured Party a continuing security interest in their
respective interests in the following (the "Collateral"):

                  All assets of the Grantors, including without limitation all
                  presently existing and hereafter arising (i) accounts,

                  books and records of the Grantors, including ledgers, records

                  liabilities of the Grantors, or the Collateral, all
                  information relating to the Grantor's business operations or
                  financial condition, all computer programs, disc or tape
                  files, printouts, runs or other computer prepared information,
                  and any equipment containing such information (the Grantors'
                  "Books"); (iii) all of the Grantors' present and hereafter
                  acquired equipment, wherever located, and all attachments,

                  future inventory in which any Grantor has any interest, and
                  all of the present and future raw materials of the Grantors,
                  work in process, finished goods, and packing and shipping

                  representing any of the above ("Inventory"); (v) all of the
                  negotiable collateral of the Grantors, including all of the

                  stock of any subsidiary), documents, personal property leases
                  (where any Grantor is the lessor), chattel paper and the books

                  any Grantor which hereafter come into the possession, custody

                  products, whether tangible or intangible, of any of the
                  foregoing including proceeds of insurance covering any or all
                  of the Collateral, and any and all Accounts, Equipment,
                  General Intangibles, Inventory, Negotiable Collateral, money,
                  deposit accounts or other tangible or intangible, real or
                  personal, property resulting from the sale, exchange,
                  collection or other disposition of the Collateral, or any
                  portion thereof or interest therein, and the proceeds thereof;

in each case howsoever the interest of any Grantor therein may arise or appear
(whether by ownership, security interest, claim or otherwise).

         The Secured Party acknowledges that its security interest in the
Collateral is junior to the liens granted to Bank of America, N.A. and the other
lenders set forth in the Credit Agreement (as defined below) (the "Senior
Lender(s)") in the Collateral, pursuant to the Credit Agreement dated as of June
30, 2000, and as subsequently amended by and between the Senior Lender(s) and
the Company (the "Credit Agreement"), and further acknowledges that it is
subject to the Intercreditor Agreement, dated the date hereof (the
"Intercreditor Agreement"), by and between the Secured Party and the Senior
Lender. The Secured Party further acknowledges and agrees that in connection
with a refinancing of the obligations of Grantors to the Senior Lenders, (a) the
security interest in the Collateral granted herein shall be junior to the liens
in favor of such replacement lenders, and (b) in order to evidence such
subordination, the Secured Party shall execute and deliver to such replacement
lenders an intercreditor and subordination agreement substantially the same as
or similar to the Intercreditor Agreement so long as the aggregate debt


                                       2

<PAGE>   3



does not exceed the limitations of Section 3.13 of the Debenture Purchase
Agreement, provided that the Secured Party's refusal to so execute and deliver
an intercreditor and subordination agreement under this Clause (b) shall in no
way limit the validity and enforceability of the foregoing Clause (a).

         SECTION 2.        Security for Obligations. The security interest
created hereby in the Collateral constitutes continuing collateral security for
the prompt payment by the company, as and when due and payable, of all amounts
from time to time owing by it to the Secured Party under the Debenture Purchase
Agreement, the Registration Rights Agreement, dated as of the date hereof
between the Company and the Secured Party, the Debentures, the 2000 Debentures,
the debenture purchase agreement pursuant to which the 2000 Debentures were
issued (the "2000 Debenture Purchase Agreement), and the Company's obligations
in respect of the Series D Preferred Stock (collectively, the "Obligations").

         SECTION 3.        Representation and Warranties. Each of the Grantors
respectively represents and warrants as follows:

                  (a)      The Grantors are and will be at all times the owners
of the Collateral free and clear of any other lien, security interest or other
charge or encumbrance except for the lien in favor of the Senior Lender and
except as described in Section 2.1(aa) of the Debenture Purchase Agreement and
Schedule 2.1(aa) thereof.

                  (b)      The chief executive office location and each
equipment and inventory location of each Grantor are set forth on Schedule 1
hereto.

                  (c)      The state of incorporation of each Grantor is set
forth on Schedule II.

         SECTION 4.        Covenants as to the Collateral. So long as any of the
Obligations shall remain outstanding, unless the Secured Party shall otherwise
consent in writing,

                  (a)      Further Assurances. Promptly after request by the
Secured Party, each Grantor will at its expense, at any time and from time to
time, promptly execute and deliver all further instruments and documents and
take all further action that may be reasonably necessary or desirable (i) to
perfect and protect the security interest to be created hereby in all
jurisdictions containing Collateral; (ii) to enable Secured Party to exercise
and enforce their rights and remedies hereunder in respect of the Collateral; or
(iii) to otherwise effect the purposes of this Agreement. Without limiting the
generality of the foregoing, the Grantors agree, promptly after request by the
Secured Party, to take such further actions as may be necessary to cause the
Secured Party's security interest in the Collateral to remain valid and
perfected after any amendment to Article 9 of the Uniform Commercial Code.

                  (b)      Provisions Concerning the Collateral. Each Grantor
will (A) give Secured Party prompt notice of any change in the Grantor's name,
identity or corporate structure, (B) keep all originals of all documents
relating to the Collateral at such Grantor's principal office, and (C) keep
adequate records concerning the Collateral and permit representatives of Secured
Party at any time during normal business hours on reasonable notice to inspect
such


                                       3

<PAGE>   4



records (provided the Secured Party agree to keep all information inspected
strictly confidential, and provided further that the Secured Party shall only be
entitled to perform such an inspection on a monthly basis so long as no Event of
Default is outstanding).

                  (c)      Transfer. The Grantors will not sell, assign,
exchange or otherwise dispose of any of the Collateral except (a) in the
ordinary course of business, (b) dispositions of worn or obsolete equipment,
provided the proceeds thereof are being used to pay Indebtedness or indebtedness
owed to the Senior Lenders, (c) encumbrances in favor of the Senior Lenders, (d)
encumbrances of specific assets in connection with the purchase money financing
thereof, (e) encumbrances in favor of the other parties which are subordinate to
the Secured Party's liens, subject to the terms of an intercreditor agreement
reasonably satisfactory to Secured Party, and (f) where the Senior Lenders have
consented to such disposition.

                  (d)      The Secured Party hereby consents to release its lien
on Collateral the sale or disposition of which (but not encumbrance) has been
approved by the Senior Lenders and the liens of the Senior Lenders on such
Collateral have been released; provided, however, that the Secured Party's lien
on the proceeds thereof shall remain, consistent with the terms of this
Agreement and the Intercreditor Agreement; further provided that the Grantors
may use and apply such proceeds in a manner permitted by the Senior Lenders.

                  (e)      If a Grantor fails to perform any agreement contained
herein, Secured Party may itself perform or cause performance of such agreement
or obligation, and the reasonable expenses of Secured Party incurred in
connection therewith shall be payable by the Company pursuant to Section 5(d)
hereof.

         SECTION 5.        Remedies Upon Default. If any of the Obligations are
not paid when due, or if the Company or any Grantor is in default of (a) any of
its obligations under this Agreement in any material respect, or (b) the
Debenture Purchase Agreement, the Debentures, the 2000 Debentures, the 2000
Debenture Purchase Agreement or Series D Preferred Stock (an "Event of
Default"), and subject to any rights of the Senior Lender:

                  (a)      The Secured Party may exercise in respect of the
Collateral in addition to other rights and remedies the rights and remedies of a
secured party under the Uniform Commercial Code in effect in the states of
Florida, Nevada or any other jurisdiction where Collateral is located (the
"Code") and also may (i) require the Grantors to, and the Grantors hereby agree
that they will at their own expense and upon request of the Secured Party
forthwith, assemble all or part of the Collateral as directed by the Secured
Party and make it available to Secured Party at a place that is reasonably
convenient to both parties to be designated by Secured Party and (ii) upon ten
(10) days' (or such longer period shall be required by law) prior written
notice, sell the Collateral or any part thereof, in one or more parcels at
public or private sale, for cash, on credit or for future delivery, and at such
price or prices and upon such other terms as the Secured Party may determine
(provided that all aspects of any such sale are commercially reasonable). The
Secured Party shall not be obligated to make any sale of Collateral regardless
of notice of sale having been given. The Secured Party may adjourn any public or
private sale from time to time by announcement at the time and placed fixed
therefor, and such sale may, without further notices, be made at the time and
place to which it was so adjourned.

                  (b)      Any cash held by the Secured Party as Collateral and
all cash proceeds received by Secured Party in respect of any sale of,
collection from, or other realization upon, all or any part of the Collateral
shall be applied in whole or in part by Secured Party against, all or any part
of the Obligations in the following order: (i) reasonable costs and expenses
incurred by The Secured Party as of such date in connection with collection of
the Obligations and enforcement of this Agreement, (ii) unpaid interest due and
owing by the Company as of such date and (iii) unpaid principal due and owing by
the Company as of such date. Any surplus of such cash or cash proceeds held by
the Secured Party and remaining after the payment in full of all of the
Obligations shall be paid over to the Company or to such person as may be
lawfully entitled to receive such surplus.

                  (c)      In the event that the proceeds of any such collection
or realization are insufficient to pay all amount to which the Secured Party is
legally entitled, the Company shall be liable for the deficiency, together with
interest thereon at the highest rate specified in the Debentures, 2000
Debentures and Series D Preferred Stock, as the case may be, for interest on
overdue principal thereof, together with the reasonable costs of collection.

                  (d)      The Company will upon demand pay to the Secured Party
the amount of any and all reasonable costs and expenses, including the
reasonable fees and disbursements of the Secured Party' counsel, which the
Secured Party may incur in connection with (i) the sale of, collection from, or
other realization upon, any Collateral, (ii) the exercise or enforcement of any
of the rights of the Secured Party hereunder, or (iii) the failure by any
Grantor to perform or observe any of the provisions hereof.

         SECTION 5A.       Power of Attorney. Each Grantor hereby irrevocably
makes, constitutes, and appoints Secured Party (and all of the Secured Party's
general partners, officers, employees, or agents designated by the Secured
Party) as its true and lawful attorney, with power to: (i) sign the Grantor's
name on any of the documents described hereunder or on any other similar
documents to be executed, recorded, or filed in order to perfect or continue
perfection of the Secured Party's security interest in the Collateral if such
Grantor has not complied with its obligations under Section 4(a) herein; (ii) at
any time that an Event of Default has occurred and is continuing, execute, sign
and endorse the Grantor's name on any invoice or bill of lading relating to any
Account, drafts against Account debtors, schedules and assignments of Accounts,
verifications of Accounts, and notices to Account debtors; (iii) send requests
for verification of Accounts; (iv) at any time that any Event of Default has
occurred and is continuing, execute, sign and endorse the Grantor's name on any
checks, notices, instruments, acceptances, money orders, drafts, warrants or
other item of payment or security that may come into the Secured Party's
possession; (v) at any time that an Event of Default has occurred and is
continuing, demand, collect, receive, receipt for, sue and recover all sums of
money or other property which may now or hereafter become due, owing or payable
from the Collateral; (vi) at any time that any Event of Default has occurred and
is continuing, file any claim or claims or, following an Event of Default, take
any action or institute or take part in any proceedings, either in its own name
or in the name of the Grantor, or otherwise, which in the discretion of the
Secured Party may seem to be necessary or advisable; (vii) at any time that an
Event of Default has occurred and following acceleration of the Indebtedness,
direct the Account debtors and other persons sending mail to the Grantor to send
all mail relating to the Collateral to the Secured Party; (viii) at any time
that an Event of Default has occurred and is continuing, make, settle, and


                                       5

<PAGE>   6


adjust all claims under the Grantor's policies of insurance and make all
determinations and decisions with respect to such policies of insurance; and
(ix) at any time that an Event of Default has occurred and following
acceleration of the Indebtedness, settle and adjust disputes and claims
respecting the Accounts directly with Account debtors, for reasonable amounts
and upon reasonable terms, and the Secured Party may cause to be executed and
delivered any documents and releases which Secured Party reasonably determines
to be necessary. The appointment of the Secured Party as the Grantor's attorney,
and each and every one of the Secured Party's rights and powers, being coupled
with an interest, is irrevocable and shall remain in full force and effect until
all of the Indebtedness has been fully repaid and performed and the Secured
Party renounces such appointment.

required or permitted to be given hereunder shall be in writing by facsimile,

         SECTION 7.        Miscellaneous.


                  (a)      No amendment of any provision of this Agreement shall
be effective unless it is in writing and signed by the Grantors and the Secured
Party, and no waiver of any provision of this Agreement shall be effective

                  (b)      No failure on the part of the Secured Party to
exercise, and no delay in exercising, any right hereunder or under any other
document relating hereto shall operate as a waiver thereof; nor shall any single

thereof or the exercise of any other right. The rights and remedies of the
Secured Party provided herein and in the Debentures, 2000 Debentures and Series
D Preferred Stock are cumulative and are in addition to, and not exclusive of,
any rights or remedies provided by law.

                  (c)      Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining portions hereof or thereof or affecting the validity
or enforceability of such provision in any other jurisdiction.

                  (d)      This Agreement shall create a continuing security
interest in the Collateral and shall (i) remain in full force and effect until
the payment in full or release of the Obligations and (ii) be binding on the
Grantors and their respective successors and assigns and shall inure, together
with all rights and remedies hereunder, to the benefit of the Secured Party and
their successors, transferee and assigns.

                  (e)      This Agreement shall be governed by and construed in

by mandatory provisions of law and except to the extent that the validity and
perfection and the effect of perfection or non-perfection of the security
interest created hereby, or remedies hereunder, in respect of any particular
Collateral are governed by the law of a jurisdiction other than the State of New
York. The parties hereby consent to the exclusive jurisdiction of any New York
State or Federal court in New York City in any action or proceeding arising
hereunder.

                  (f)      The actions of the holders of a majority-in-interest
