                              SUBSIDIARY GUARANTEE

         GUARANTEE, dated as of September 24, 2002 ("GUARANTEE"), is being made
by each of the undersigned wholly-owned subsidiaries of U.S. Plastic Lumber
Corp. (each, a "GUARANTOR") in connection with the Exchange and Repurchase
Agreement, dated as of September 24, 2002 (the "EXCHANGE AGREEMENT"), by and
between U.S. Plastic Lumber Corp. (the "COMPANY") and Halifax Fund, L.P. (the
"HOLDER"). Capitalized terms used herein and not otherwise defined shall have
the respective meanings set forth in the Exchange Agreement.

         WHEREAS, subject to the terms and conditions of the Exchange Agreement,
the Holder has agreed to enter into the exchange and repurchase transactions
described therein, pursuant to which the Holder will tender for exchange and
repurchase the securities of the Company then held by the Holder (the "EXISTING
SECURITIES"), and following which the Holder will hold the Company's (i) 10%
Convertible Subordinated Debenture due March 24, 2006 (the "SUBORDINATED
DEBENTURE") and (ii) 10% Subordinated Note due March 24, 2006 (the "SUBORDINATED
NOTE" and, together with the Subordinated Debenture, the "EXCHANGE SECURITIES");

         WHEREAS, the Company owns, directly or indirectly, all of the issued
and outstanding capital stock of each Guarantor;

         WHEREAS, each Guarantor derived substantial direct and/or indirect
benefits from the funding made in connection with the issuance of the Existing
Securities, and will derive similar benefits from the restructuring of the
Company's obligations pursuant to the Exchange Agreement; and

         WHEREAS, it is a condition precedent to the obligations of the Holder
under the Exchange Agreement that the Guarantors shall have executed and
delivered this Guarantee to the Holder.

         NOW, THEREFORE, in order to induce the Holder to enter into the
Exchange Agreement, each Guarantor hereby agrees with the Holder as follows:

1.       DEFINITIONS.

                  1.1 CERTAIN DEFINITIONS. When used herein, the following terms
shall have the respective meanings indicated:

                  "OBLIGATIONS" means all of the obligations and liabilities of
the Company to the Holder relating to the payment of money (including, without
limitation, all of the interest that accrues on the Exchange Securities after
the Exchange Securities become due and payable and all interest that accrues on
the Exchange Securities after the filing of any petition in bankruptcy, or the
commencement of any insolvency, reorganization or similar proceeding, relating
to the Company whether or not a claim for post-filing or post-petition interest
is allowed in such proceeding), whether direct or indirect, absolute or
contingent, due or to become due, now existing or hereafter incurred, that may
arise under, with respect to, or in connection with the Exchange Agreement, any
of the other Transaction Documents or any other document, agreement or

                                      -1-
<PAGE>

instrument made, delivered or given in connection with the Exchange Agreement or
any other Transaction Document, whether on account of principal, interest, fees,
indemnities, costs, expenses or otherwise (including, without limitation, all
fees and expenses of counsel to the Holder that are required to be paid by the
Company pursuant to the terms of the Exchange Agreement, any of the other
Transaction Documents or any other document, agreement or instrument made,
delivered or given in connection with the Exchange Agreement or any other
Transaction Document).

                  "TERMINATION DATE" means the first date on which all of the
Obligations have been finally paid in cash; PROVIDED, HOWEVER, that the
Termination Date shall be deemed extended if the Company enters into any
bankruptcy or similar proceeding at a time when any amount paid to the Holder
could be ordered to be repaid as a preference or pursuant to a similar theory,
and shall not be deemed to occur until the date on which it is finally
determined that no such repayment can be ordered.

                  1.2 OTHER DEFINITIONAL PROVISIONS. Unless otherwise specified
in this Guarantee, the words "hereof," "herein" and "hereunder" and words of
similar import when used in this Guarantee shall refer to this Guarantee as a
whole and not to any particular provision of this Guarantee. The meanings given
to terms defined in this Guarantee shall be equally applicable to both the
singular and plural forms of such terms.

2.       GUARANTEE.

                  2.1 UNCONDITIONAL GUARANTEE. Subject to the provisions of
SECTION 2.2 of this Guarantee, each Guarantor, jointly and severally,
unconditionally and irrevocably guarantees to the Holder the punctual and
complete payment and performance by the Company of each of the Obligations as
and when such Obligation becomes due (whether at stated maturity, by
acceleration or otherwise).

                  2.2 APPLICABLE LAW. Notwithstanding anything in this Guarantee
to the contrary, the maximum liability of each Guarantor under this Guarantee
shall in no event exceed the amount that can be guaranteed by such Guarantor
under applicable federal and state laws (including, without limitation, laws
relating to the insolvency of debtors). Each Guarantor agrees that the aggregate
amount of the Obligations may at any time exceed the maximum amount of such
Guarantor's liability under this Guarantee without affecting this Guarantee or
in any way impairing the rights and remedies of the Holder against any of the
Guarantors under this Guarantee.

                  2.3 COSTS OF COLLECTION. Each Guarantor jointly and severally
agrees to pay all of the fees, expenses and costs (including, without
limitation, all reasonable fees and expenses of counsel) that may be paid or
incurred by the Holder in enforcing or obtaining advice of counsel regarding any
rights with respect to, or collecting, any of the Obligations or enforcing any
rights with respect to, or collecting against, the Guarantors under this
Guarantee.

3.       SUBROGATION OF RIGHTS.

                  Notwithstanding any payment by any Guarantor under this
Guarantee to the Holder or any set-off or application of any Guarantor's funds
by the Holder, no Guarantor shall be entitled to exercise any right of
subrogation that such Guarantor may have as a result of this Guarantee (whether
contractual, under any provision of the bankruptcy code or any other law, or
otherwise), until after the Termination Date. If any amount is paid to a
Guarantor on account of any subrogation right at any time prior to the
Termination Date, such Guarantor shall promptly (but in no event later than one
(1) Business Day after receipt of any such amount) turn over such amount in full
(in the exact form received by such Guarantor and duly indorsed by such
Guarantor to the Holder if necessary) to the Holder; PROVIDED, HOWEVER, that
until such amount has been turned over to the Holder, (i) the Guarantor shall
hold such amount in trust for the Holder, and (ii) such amount shall be
segregated from all other assets and property of the Guarantor.

4.       AMENDMENT OF TRANSACTION DOCUMENTS; RELEASE OF COLLATERAL.

                  4.1 TRANSACTION DOCUMENTS; COLLATERAL. The Holder may (except
as shall be required by applicable law) at any time and from time to time
without the consent of, or notice to, any Guarantor, without incurring any
liability or responsibility to any Guarantor, and without impairing or releasing
the obligations of any Guarantor under this Guarantee:

                           (i) change the manner, place or terms of payment of,
and/or change or extend the time of payment of, renew, increase, accelerate or
alter, any of the Obligations, any security therefor, or any liability incurred
directly or indirectly in respect of the Obligations, and the guaranty made
pursuant to this Guarantee shall apply to the Obligations as so changed,
extended, renewed or altered;

                           (ii) sell, exchange, release, surrender, realize upon
or otherwise deal with in any manner and in any order any property pledged or
mortgaged to secure the Obligations or any liabilities incurred directly or
indirectly in respect of the Obligations or this Guarantee;

                           (iii) exercise or refrain from exercising any rights
or remedies against the Company or any other Person (including any Guarantor) or
otherwise act or refrain from acting with respect to the Company or other Person
(including without limitation, any Guarantor);

                           (iv) settle or compromise any of the Obligations, any
security therefor or any liability (including any of those under this Guarantee)
incurred directly or indirectly in respect of the Obligations, or subordinate
the payment of all or any part of the Obligations to the payment of any other
liability (whether due or not) of the Company;

                           (v) apply any sums by whomsoever paid or howsoever
realized to any liability or liabilities of the Company to the Holder regardless
of what liabilities of the Company remain unpaid;

                                      -3-
<PAGE>

                           (vi) consent to or waive any breach of, or any act,
omission or default under, any of the Transaction Documents or any of the
documents, instruments or agreements made, delivered or given in connection with
the Transaction Documents, or otherwise amend, modify, supplement, cancel or
terminate any of the Transaction Documents or any of the instruments, documents,
or agreements made, delivered or given in connection with the Transaction
Documents;

                           (vii) act or fail to act in any manner referred to in
this Guarantee which may deprive any Guarantor of its right to subrogation
against the Company or any other Person (including any other Guarantor) to
recover full indemnity for any payments made by such Guarantor pursuant to this
Guaranty; and/or

                           (viii) release or substitute the Company or any
endorser, guarantor or other obligor.

                  4.2 HOLDER ACTION. The Holder shall not have any obligation at
any time to take any action, or expend any funds, to (i) secure or perfect any
Lien that is required to be granted by the Company as collateral security for
the Obligations, or (ii) insure or otherwise protect any assets or property that
is subject to a Lien granted by the Company as collateral security for the
Obligations.

5.       OBLIGATIONS OF GUARANTORS.

                  5.1 GUARANTEE ABSOLUTE AND UNCONDITIONAL. (a) Each Guarantor
hereby waives any and all notice of the creation, renewal, extension or accrual
of any of the Obligations and notice or proof of reliance by the Holder upon
this Guarantee or acceptance of this Guarantee; each Obligation shall
conclusively be deemed to have been created, contracted or incurred, or renewed,
extended, amended or waived in reliance upon this Guarantee; and all dealings
between the Company and the Guarantors, on the one hand, and the Holder, on the
other hand, shall be conclusively presumed to have been consummated in reliance
upon this Guarantee. Each Guarantor understands and agrees that this Guarantee
shall be construed as a continuing, absolute and unconditional guarantee of
payment without regard to (i) the validity or enforceability of (1) the Exchange
Agreement, the Exchange Securities, any of the other Transaction Documents or
any document, instrument or agreement made, delivered or given in connection
with the Exchange Agreement, the Exchange Securities or any other Transaction
Document, (2) any Lien securing the Obligations, (3) any of the collateral
security for, or any guarantee of, the Obligations, or (4) any right of offset
with respect to the Obligations, (ii) any defense, set-off or counterclaim that
may at any time be available to, or be asserted by, the Company against the
Holder, or (iii) any other circumstance whatsoever (including, without
limitation, insolvency or bankruptcy of the Company or any other Person) that
constitutes (or might be construed to constitute) an equitable or legal
discharge of the Obligations or the obligations and liabilities of the
Guarantors under this Guarantee, regardless of whether any Guarantor has notice
or knowledge of any such circumstance.

<PAGE>

                  5.2 OBLIGATIONS NOT AFFECTED. None of the obligations and
liabilities of any of the Guarantors under this Guarantee shall be relieved or
reduced, and none of the rights and remedies of the Holder against the
Guarantors shall be impaired or adversely affected, as a result of (i) any
demand by the Holder for payment of any of the Obligations being subsequently
rescinded, (ii) any amendment, modification, supplement or termination of the
Exchange Agreement, the Exchange Securities, any other Transaction Document or
any document, agreement or instrument made, delivered or given in connection
with the Exchange Agreement, the Exchange Securities or any other Transaction
Document, or (iii) any or all of the collateral security for, or any other
guarantee of, the Obligations or any right of offset with respect to the
Obligations being renewed, extended, amended, modified, accelerated,
compromised, waived, surrendered or released, in whole or in part, by the Holder
at any time.

                  5.3 WAIVER OF NOTICE. Each Guarantor hereby waives (to the
fullest extent permitted by applicable law) notice of (i) acceptance of this
Guarantee and notice of any liability to which it may apply, (ii) promptness,
diligence, presentment, demand of payment or performance, protest, notice of
dishonor, nonpayment or nonperformance of any of the Obligations, and (iii) any
suit or taking of other action by the Holder against, and any other notice to,
any Person liable on or with respect to the Obligations (including such
Guarantor or any other guarantor of the Company). When pursuing any of its
rights and remedies against the Guarantors, the Holder may, but shall be under
no obligation to, pursue any other rights and remedies that it may have against
the Company or any other Person (including any other Guarantor) or against any
collateral security for, or any guarantee of, the Obligations or any right of
offset that it may have with respect to the Obligations; PROVIDED, HOWEVER, that
none of the obligations and liabilities of the Guarantors under this Guarantee
will be relieved or reduced, and none of the rights of the Holder will be
impaired or adversely affected, as a result of any failure by the Holder to (i)
pursue any rights or remedies that it may have against the Company or any other
Person (including any other Guarantor), (ii) collect any amounts that are due
any payable with respect to the Obligations from the Company or any other Person
(including any other Guarantor), or (iii) realize upon any collateral security
or guarantee or exercise any right of offset. Each Guarantor waives any right
(to the fullest extent permitted by applicable law) to require the Holder to:
(i) proceed against the Company, any other Guarantor, any other guarantor of the
Company or any other Person; (ii) proceed against or exhaust any security held
from the Company, any other Guarantor, any other guarantor of the Company or any
other Person; or (iii) pursue any other remedy against the Company, any other
Guarantor, any other guarantor of the Company or any other Person. Each
Guarantor waives (to the fullest extent permitted by applicable law) any defense

                                      -5-
<PAGE>

based on or arising out of any defense of the Company, any other Guarantor, any
other guarantor of the Company or any other Person other than payment in full of
the Obligations, including, without limitation, any defense based on or arising
out of the disability of the Company, any other Guarantor, any other guarantor
of the Company or any other Person, or the unenforceability of the Obligations
or any part thereof from any cause, or the cessation from any cause of the
liability of the Company other than payment in full of the Obligations. The
Holder may, at its election, foreclose on any security held by the Holder by one
or more judicial or nonjudicial sales, or exercise any other right or remedy the
Holder may have against the Company or any other Person, or any security,
without affecting or impairing in any way the liability of any Guarantor under
this Guarantee except to the extent the Obligations have been paid in full. Each
Guarantor waives any defense arising out of any such election by the Holder,
even though such election operates to impair or extinguish any right or
reimbursement or subrogation or other right or remedy of such Guarantor against
the Company or any other Person or any security (to the extent permitted by
applicable law).

                  5.4 NO IMPAIRMENT. The liability of each Guarantor under this
Guarantee is exclusive and independent of any security for or other guaranty of
the Obligations, whether executed by such Guarantor, any other Guarantor, any
other guarantor or by any other Person, and the liability of each Guarantor
under this Guarantee shall not be affected or impaired by (a) any direction as
to application of payment by the Company or by any other Person, (b) any other
continuing or other guaranty, undertaking or maximum liability of a guarantor of
the Company or of any other Person as to the Obligations, (c) any payment on or
in reduction of any such other guaranty or undertaking, (d) any dissolution,
termination or increase, decrease or change in personnel by the Company, (e) any
payment made to the Holder which is repaid to the Company pursuant to a court
order in any bankruptcy, reorganization, arrangement, moratorium or other debtor
relief proceeding, and each Guarantor waives any right to the deferral or
modification to its obligations hereunder by reason of any of such proceeding,
(f) any action or inaction by the Holder, or (g) any invalidity, irregularity or
unenforceability of all or part of the Obligations or of any security therefor.

                  5.5 SEVERABILITY OF OBLIGATIONS; STATUTE OF LIMITATIONS. The
obligations of each Guarantor under this Guarantee are independent of the
obligations of any other Guarantor, any other guarantor of the Company, or any
other Person, and a separate action or actions may be brought and prosecuted
against each Guarantor whether or not action is brought against any other
Guarantor, any other guarantor of the Company or any other Person and whether or
not any other Guarantor, any other guarantor of the Company or any Person be
joined in any such action or actions. Each Guarantor waives, to the fullest
extent permitted by law, the benefit of any statute of limitations affecting its
liability under this Guarantee or the enforcement of any such statute of
limitations. Any payment by the Company or other circumstance that operates to
toll any statute of limitations as to the Company shall operate to toll the
statute of limitations as to each Guarantor.

                  5.6 SUBORDINATION. Any indebtedness of the Company now or
hereafter held by the Guarantors is hereby subordinated in all respects to all
of the Obligations; and if requested by the Holder after an Event of Default
under either or both of the Exchange Securities has occurred and is continuing,
and the obligations of the Company thereunder have been accelerated, the
indebtedness of the Company to any Guarantor shall be collected, enforced and
received by such Guarantor as trustee for the Holder and such Guarantor shall
promptly (but in no event later than one (1) Business Day after receipt of any
such amounts) turn over such amounts to the Holder; PROVIDED, HOWEVER, that no
such collection or enforcement shall in any way affect or impair the liability
of such Guarantor under any of the provisions of this Guarantee. Prior to the
transfer by any Guarantor of any note or negotiable instrument evidencing any
indebtedness of the Company to such Guarantor, such Guarantor shall mark such
note or negotiable instrument with a legend that it is subordinated in all
respects to all of the Obligations.

                                      -6-
<PAGE>

                  5.7 AUTHORITY. It shall not be necessary for the Holder to
inquire into the authority, capacity or powers of the Company or any of its
Subsidiaries or the officers, directors, partners or agents acting or purporting
to act on its behalf, and any indebtedness made or created in reliance upon the
professed exercise of such powers shall be guaranteed under this Guarantee.

                  5.8 REINSTATEMENT. Notwithstanding any other provision of this
Guarantee to the contrary, if any payment with respect to the Obligations is
rescinded or required to be restored or returned by the Holder for any reason
whatsoever (including, without limitation, as a result of the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Company or the
appointment of a receiver, intervenor or conservator of, or trustee or similar
officer for, the Company or any of its assets or properties), this Guarantee
shall continue to be effective, and shall be reinstated if previously
terminated, as though such payment had not been made.

                  5.9 PAYMENTS. Each Guarantor hereby covenants and agrees that
all amounts due and payable by such Guarantor under this Guarantee shall be paid
to the Holder without set-off or counterclaim by wire transfer of immediately
available United States dollar funds to such account as the Holder may designate
in writing to such Guarantor from time to time.

6.       REPRESENTATIONS AND WARRANTIES.

                  6.1 REPRESENTATIONS AND WARRANTIES. Each Guarantor hereby

delay in exercising, any right, power or privilege of the Holder under this
Guarantee, any other Transaction Document or any document, agreement or
instrument made, delivered or given in connection with this Agreement or the
other Transaction Documents shall operate as a waiver of any such right, power
or privilege. No single or partial exercise of any right, power or privilege
under this Guarantee, any other Transaction Document or any document, agreement
or instrument made, delivered or given in connection with this Agreement or the
other Transaction Documents shall preclude any other or further exercise of any
other right, power or privilege. A waiver by the Holder of any right or remedy
under this Guarantee, any other Transaction Document or any other document or
instrument made, delivered or given in connection with this Agreement or the
other Transaction Documents on any one occasion shall not be construed as a bar
to any right or remedy that the Holder would otherwise have on any future
occasion.

                  7.6 CUMULATIVE REMEDIES. The rights and remedies provided in
this Guarantee are cumulative, may be exercised singly or concurrently, and are
not exclusive of any other rights or remedies provided by law.

                  7.7 SECTION HEADINGS. The section headings used in this
Guarantee are for convenience of reference only and are not to affect the
construction of this Guarantee or be taken into consideration in the
interpretation of this Guarantee.

                  7.8 INDEMNIFICATION. Each Guarantor agrees to jointly and
severally indemnify and hold harmless the Holder and each of its directors,
officers, employees, advisors and agents (each, an "INDEMNIFIED PERSON") from
and against, and shall pay each Indemnified Person as and when incurred, all
claims, damages, losses, liabilities, costs and expenses of any kind whatsoever,
including reasonable fees and expenses of attorneys and paralegals, that such
Indemnified Person may incur as a result of third party claims (or that may be
claimed against such Indemnified Person by any Person), together with all costs
and expenses resulting from the compromise or defense of any claims or
liabilities, by reason of or in connection with (i) the preparation, execution,
delivery, validity, enforceability or performance of this Guarantee, the other
Transaction Documents to which such Guarantor is a party and the other
documents, agreements and instruments made, delivered or given by such Guarantor
in connection with this Agreement or any of the other Transaction Documents,
(ii) any action taken by any Indemnified Person pursuant to, or in connection
with, this Guarantee, any of the other Transaction Documents to which such
Guarantor is a party or any other document, agreement or instrument made,
delivered or given by such Guarantor in connection with this Agreement or any of
the other Transaction Documents, (iii) any breach by such Guarantor of any
warranty, covenant, term or condition in, or the occurrence of any default
under, this Guarantee, any of the other Transaction Documents to which such
Guarantor is a party or any other document, agreement or instrument made,

                                      -10-
<PAGE>

delivered or given by such Guarantor in connection with this Agreement or any of
the other Transaction Documents, and (iv) any inquiry, investigation,
litigation, proceeding or other action related to or arising out of this
Guarantee, any of the other Transaction Documents to which such Guarantor is a
party or any other document, agreement or instrument made, delivered or given by
such Guarantor in connection with this Agreement or any of the other Transaction
Documents (whether or not such Indemnified Party is a party to such
investigation, litigation, proceeding or other action and whether any such
investigation, litigation or proceeding or other action is brought by the
Company, such Guarantor, any shareholder or creditor of the Company or such
Guarantor or any other Person); PROVIDED, HOWEVER, that such Guarantor shall not
be required to indemnify an Indemnified Person for any claims, damages, losses,
liabilities, costs or expenses to the extent, but only to the extent, caused
solely by the gross negligence or willful misconduct of such Indemnified Person
(as determined in a final, non-appealable judgment in a court of competent
jurisdiction). In case any action or proceeding is brought against an
Indemnified Person in respect of which indemnity may be sought under this
Guarantee, such Indemnified Person shall promptly give notice of any such action
or proceeding to each Guarantor and may require each Guarantor, upon such
notice, to assume the defense of the action or proceeding, PROVIDED that the
failure of an Indemnified Person to give such notice shall not relieve any
Guarantor of its obligations under this SECTION 7.8. Upon receipt of notice from
an Indemnified Person requesting that the Guarantors assume the defense of any
action or proceeding, each Guarantor shall resist and defend such action or
proceeding at its sole cost and expense. The obligations of the Guarantors under
this SECTION 7.8 shall survive the termination of this Guarantee.

                  7.9 SUCCESSORS AND ASSIGNS. This Guarantee shall be binding
upon each Guarantor and its successors and assigns and this Guarantee shall
inure to the benefit of the Holder and its successors, indorsees, transferees
and assigns. No Guarantor may assign any of its rights under, or delegate any of
its duties or obligations under, this Guarantee without the prior written
consent of the Holder.

                  7.10 SETOFF AND ADJUSTMENTS. In addition to any right now or
hereafter granted under applicable law, upon the occurrence and during the
continuance of an Event of Default under the Exchange Securities, the Holder is
hereby authorized at any time or from time to time, without notice to any
Guarantor or to any other Person (any such notice being expressly waived by all
of the Guarantors) to setoff and to appropriate and apply any and all deposits
(general or special) and any other indebtedness at any time held or owing by the
Holder to or for the credit or the account of such Guarantor, against and on
account of the obligations and liabilities of such Guarantor to the Holder under
this Guaranty, irrespective of whether or not (i) the Holder shall have made any
demand under this Guarantee, or (ii) such obligations and liabilities are
contingent or unmatured.

                  7.11 GOVERNING LAW. This Agreement shall be governed by and
construed under the laws of the State of New York applicable to contracts made
and to be performed entirely within the State of New York.

                  7.12 SUBMISSION TO JURISDICTION; WAIVERS. Each Guarantor
hereby irrevocably and unconditionally:

                           (a) submits itself and its property to any legal
action or proceeding relating to this Guarantee, any of the other Transaction
Documents or any document, agreement or instrument made, delivered or given in

instrument, to the non-exclusive general jurisdiction of the courts of the State
of New York, the courts of the United States of America for the Southern
District of New York, and the appellate courts for such state and federal
courts;

                           (b) consents that any such action or proceeding may
be brought in such courts and waives any objection that it may now or hereafter
have to the venue of any such action or proceeding in any such court or that
such action or proceeding was brought in an inconvenient court and agrees not to
plead or claim the same;

                           (c) agrees that service of process in any such action
or proceeding may be effected by registered or certified mail (or any
substantially similar form of mail), postage prepaid to such Guarantor at its
address set below its signature to this Guarantee or at such other address as
such Guarantor shall have notified the Holder pursuant to the terms of this
Guarantee;

                           (d) agrees that nothing in this Guarantee shall
affect the right of the Holder to effect service of process in any other manner
permitted by law or shall limit the right of the Holder to sue in any other
jurisdiction; and

                           (e) waives, to the fullest extent permitted by law,
any right any Guarantor may have to claim or recover any special exemplary,
punitive or consequential damages in any legal action or proceeding that relates
to, or that arises from, this Guarantee, any of the other Transaction Documents
or any other document, agreement or instrument made, delivered or given in
connection with this Guarantee or any of the other Transaction Documents.

                  7.13 WAIVERS OF JURY TRIAL. Each Guarantor hereby irrevocably
and unconditionally waives trial by jury in any legal action or proceeding
relating to this Guarantee or any other Transaction Document to which it is a
party and for any counterclaim therein.

                  7.14 COMPLIANCE WITH EXCHANGE AGREEMENT. Each Guarantor
covenants and agrees that on and after the date hereof and until all Obligations
have been paid in full, such Guarantor shall take, or will refrain from taking,
all actions that are necessary to be taken or not taken so that no violation of
any covenant or agreement of the Company contained in the Exchange Agreement is
caused by the actions of such Guarantor or any of its Subsidiaries. The
Guarantors hereby jointly and severally agree to pay all reasonable
out-of-pocket costs and expenses of the Holder in connection with the
enforcement of this Guarantee and any amendment, waiver or consent relating
hereto (including, without limitation, reasonable legal fees and disbursements).

         2.3 PAYMENTS. (a) Notwithstanding any provision of this Agreement to
the contrary, (i) at all times prior to the earlier to occur of (x) the
commencement of any Proceeding and (y) the receipt by Halifax of notice from
Agent of the commencement of any other Senior Enforcement Action, Halifax and
Holders may accept from any Credit Party regularly scheduled payments of
principal and/or interest at the respective times and in the respective amounts
required pursuant to the Halifax Documents without regard to whether such
payments constitute proceeds of Senior Bank Collateral (IT BEING UNDERSTOOD that
during the period beginning on the date of issue of the Subordinated Debenture
and the Subordinated Note and ending on the second anniversary of such issue
date, USPL may elect to pay interest that becomes due on a Scheduled Payment
Date (as defined in the Subordinated Debenture and the Subordinated Note) by
increasing the principal balance of such notes); (ii) the Halifax Indebtedness
may be converted into or exchanged for Junior Securities; and (iii) Halifax may
receive and retain any payment made solely in Junior Securities.

         (b) Except as provided in SECTION 2.3(a)(ii) and (iii), no direct or
indirect payment (including by way of set-off) by any Credit Party in respect of
the Halifax Indebtedness, whether upon acceleration or otherwise, shall be made
if at the time of such payment there exists (x) a default in the payment when
due (whether upon acceleration or otherwise) of any principal of, or any
interest on or fees included in, any Senior Indebtedness; or (y) subject to the
following sentences of this paragraph, a matured event of default (other than a
default specified in the preceding CLAUSE (X)) under the Senior Credit Agreement
(an "OTHER SENIOR DEFAULT") and Halifax and USPL have received notice from Agent
or any Senior Bank, in the manner specified in SECTION 16 hereof, of such event
of default (a "SENIOR DEFAULT NOTICE"). With respect to any Other Senior
Default, the period during which no payment on account of Halifax Indebtedness
may be made to or retained by Halifax shall commence only upon giving of a
Senior Default Notice as provided above and shall end at the first to occur of
(x) completion of the 180th day after the beginning of such period, (y) the cure
or waiver of all defaults existing at the time of the applicable Senior Default
Notice or (z) the payment in full in cash of the Senior Indebtedness (the
"PAYMENT BLOCKAGE PERIOD"). Upon termination of any Payment Blockage Period,
USPL may resume payments on account of the Halifax Indebtedness (including any
missed payments) subject to the provisions of SECTION 2.3(a). Only one Senior
Default Notice may be given in any period of 360 consecutive days, and no Other
Senior Default which was in existence on the date of a Senior Default Notice may
be used as the basis for a subsequent Senior Default Notice (it being understood
that any action, or breach of a financial covenant, which occurs after the date
on which a Senior Default Notice is given that, in either case, would give rise
to a matured event of default pursuant to any provision of the Senior Credit
Agreement under which a matured event of default existed shall constitute a new
matured event of default for purposes of this paragraph).

         SECTION 3. ENFORCEMENT.

indefeasible payment in full in cash of all Senior Indebtedness and the Senior
Credit Documents and all Senior Commitments thereunder shall have terminated
pursuant to the respective terms and provisions thereof, except for its receipt
of payments expressly permitted by SECTION 2.3, neither Halifax nor any other
Holder shall exercise any right or remedy in respect of all or any part of the
Senior Bank Collateral and Halifax and each Holder agrees not to take or receive
from any Credit Party, directly or indirectly, in cash or other Property or by
set-off or in any other manner, whether pursuant to any enforcement, collection,
execution, levy or foreclosure proceeding or otherwise, all or any part of the
Senior Bank Collateral. Without limiting the generality of the foregoing, unless
and until Agent and each Senior Bank shall have received indefeasible payment in
full in cash of all Senior Indebtedness and the Senior Credit Documents and all
Senior Commitments thereunder shall have terminated pursuant to the respective
terms and provisions thereof, (i) neither Halifax nor any other Holder shall
exercise or otherwise assert any right or remedy in respect of all or any part
of the Senior Bank Collateral or any Lien thereon; (ii) the sole right of
Halifax with respect to the Senior Bank Collateral shall be to hold a Lien
thereon to the extent granted pursuant to the Halifax Documents and to receive
proceeds thereof remaining after such payment and termination; and (iii) without
the prior written consent of Agent, neither Halifax nor any other Holder shall
exercise any right Halifax may have under the Halifax Documents or under the UCC
or other applicable law to deliver any notices to account debtors informing them
of Halifax's interest in any accounts of any Credit Party or directing such
account debtors to make payments in any particular manner of amounts due in
respect of any such account.

         3.2 COOPERATION. Halifax agrees that, unless and until Agent and each
Senior Bank shall have received indefeasible payment in full in cash of all
Senior Indebtedness and the Senior Credit Documents and all Senior Commitments
thereunder shall have terminated pursuant to the respective terms and provisions
thereof, neither Halifax nor any other Holder will commence, or join with any
creditor other than Agent in commencing, any enforcement, collection, execution,
levy or foreclosure proceeding with respect to any Lien held by it in, or
otherwise with respect to, all or any part of the Senior Bank Collateral,
including, without limitation, petitioning, filing or joining in any involuntary
Proceeding pursuant to Section 303 of the Bankruptcy Code.

         3.3 JUDGMENT LIENS. Notwithstanding the provisions of SECTION 3.1 and
3.2, if Halifax obtains a final judgment against any Credit Party for any unpaid
amount payable in respect of the Halifax Indebtedness and, as a result of such
judgment, Halifax obtains a judgment Lien on any property of any Credit Party,
then Halifax may take any action permitted by applicable law to enforce such
judgment Lien against such property (subject, if such property constitutes
Senior Bank Collateral, to the rights of the Agent arising under applicable law
with respect to such property).

         SECTION 4. LIQUIDATION; DISSOLUTION; BANKRUPTCY. In the event of any
Proceeding involving any Credit Party, or any sale, transfer or other
disposition of all or substantially all of the assets of any Credit Party:

                                      -6-
<PAGE>

         (a) Halifax agrees:

                  (i) that Senior Banks may consent to the use of cash
collateral or the provision of financing to Credit Parties on such terms and
conditions and in such amounts as Senior Banks, in their sole discretion, may
decide and that, in connection with such cash collateral usage or such
financing, as the case may be, each Credit Party (or a trustee appointed for the
estate of any Credit Party) may grant to Agent, for the benefit of Agent and
Senior Banks, Liens on all of such Credit Party's Property, which Liens (x)
shall secure payment, performance and observance of all Senior Indebtedness
(whether such Senior Indebtedness arose prior to the commencement of any
Proceeding or at any time thereafter) and (y) shall be superior in priority to
the Liens in favor of Halifax on any Property of any Credit Party;

                  (ii) that it will not object to or oppose a sale or other
disposition of any Property of any Credit Party securing all or any part of the
Senior Indebtedness free and clear of Liens or other claims of Halifax under
Section 363 of the Bankruptcy Code or any other provision of the Bankruptcy Code
if Senior Banks have consented to such sale or disposition;

                  (iii) agrees that it will not seek to have the automatic stay
lifted with respect to any Senior Bank Collateral, to appoint a Chapter 11
trustee under Section 1104 of the Bankruptcy Code or to convert or dismiss such
Proceeding under Section 1112 of the Bankruptcy Code, in each case without the
prior written consent of Agent;

                  (iv) to waive in any Proceeding under the Bankruptcy Code any
claim it may now or hereafter have under Section 1111(b)(2) of the Bankruptcy
Code, including, without limitation, any such claim arising out of the election
by Senior Banks of the application of Section 1111(b)(2) of the Bankruptcy Code,
and/or any borrowing or grant of a security interest under Section 364 of the
Bankruptcy Code by any Credit Party, as debtor in possession; and

                  (v) that to the extent it receives any "adequate protection"
for any interest it may have in any Senior Bank Collateral in any Proceeding, it
will (A) if such "adequate protection" is in the form of cash or cash
equivalents, deliver such "adequate protection" to the Agent to be applied to,
or held as collateral for (and, if liquidated, applied against), the Senior
Indebtedness, and (B) if such "adequate protection" is in any other form, assign
such "adequate protection" to the Agent to be held as collateral for (and, if
liquidated, to be applied against) the Senior Indebtedness, in each case until
all Senior Indebtedness has been fully satisfied or is no longer outstanding.

         (b) Halifax shall not, directly or indirectly, take any action or vote
in any way that would be in violation of, or inconsistent with, or result in a
breach of, this Agreement or challenge or contest in any Proceeding, or in
connection with any other enforcement, collection, execution, levy or
foreclosure proceeding or otherwise, (i) the validity, perfection, priority or
enforceability of any Liens held by Agent or any Senior Bank to secure the
payment, performance or observance of all or any part of the Senior
Indebtedness, (ii) the rights of Agent and Senior Banks set forth in any of the
Senior Credit Documents with respect to such Liens, or (iii) the validity or
enforceability of any of the Senior Credit Documents or any term, condition or
provision of this Agreement.

                                      -7-
<PAGE>

         (c) Subject to the limitations set forth in this Agreement, Halifax may
file proofs of claim and other pleadings and motions with respect to the Senior
Bank Collateral in such Proceeding.

         (d) Halifax shall execute and deliver to Agent all such instruments and
other documentation confirming the above authorizations and all such proofs of
claim, assignments of claim and other instruments and documentation, and shall
take all such other action as may be reasonably requested by Agent to enforce
such claims and carry out the purpose of this SECTION 4.

         (e) The agreements of Halifax set forth in this SECTION 4 are solely
for the benefit of the Agent and each Senior Bank. Without limiting the
foregoing, no agreement of Halifax set forth in this SECTION 4, and no action or
inaction of Halifax in accordance with the terms hereof (including, without
limitation, any failure to object to any sale or other disposition of property
or any waiver of any right) shall constitute a relinquishment by Halifax of any
Lien it may have on any property of any Credit Party (other than property which
has been sold or otherwise disposed of by such Credit Party as provided above)
or a waiver by Halifax of any priority it may have over any other creditor of
any Credit Party.

         SECTION 5. INSURANCE AND CONDEMNATION; RELEASES OF LIENS; EFFECT OF
REFINANCING.

         (a) Unless and until Agent and each Senior Bank shall have received
indefeasible payment in full in cash of all Senior Indebtedness and the Senior
Credit Documents and all Senior Commitments thereunder shall have terminated
pursuant to the respective terms and provisions thereof, (i) Halifax agrees that
Agent shall have the sole and exclusive right to adjust settlement with respect
to any insurance coverage for any Senior Bank Collateral and (ii) all proceeds
of any insurance policy, and proceeds of any condemnation or similar proceeding,
covering all or any part of the Senior Bank Collateral shall be paid to Agent
for application pursuant to the Senior Credit Documents. If Senior Banks allow
any portion of any proceeds of any insurance, condemnation or similar award with
respect to any Senior Bank Collateral to be used by any Credit Party to repair
or replace the Senior Bank Collateral affected, Halifax agrees to take promptly
all action reasonably requested by Agent to permit such use.

         (b) If Agent releases any of its Liens on all or any part of the Senior
Bank Collateral in connection with the sale or other disposition thereof
(including the sale of all or a portion of the stock or assets of USPL and/or
any subsidiary thereof) or pursuant to any Senior Enforcement Action by Agent or
any Senior Bank or otherwise (other than in connection with a refinancing as
described in SECTION 5(c) below), Halifax shall thereupon promptly execute and
deliver to Agent such termination statements and releases as Agent shall
reasonably request to effect the release of Halifax's Lien thereon. In
furtherance of the foregoing, Halifax hereby appoints Agent as its
attorney-in-fact, with full authority in the place and stead of Halifax and full
power of substitution and in the name of Halifax or otherwise, to execute and
deliver any document or instrument which Halifax is required to deliver pursuant
to this SECTION 5(b), such appointment being coupled with an interest and
irrevocable.

         (c) Halifax agrees that if the Senior Indebtedness is refinanced, (i)
all Liens of Halifax on the Senior Bank Collateral will continue to be junior
and subordinate to the Liens of

                                      -8-
<PAGE>

the replacement lender or lenders (or any agent therefor) and (ii) in order to
evidence such subordination, Halifax shall, upon the request of any Credit Party
or such replacement lender or lenders (or any agent therefor), execute and
deliver to such replacement lender or lenders (or any agent therefor) a
subordination and intercreditor agreement containing terms no less favorable to
Halifax than this Agreement (and prior to such execution and delivery, all of
the terms of this Agreement shall inure to the benefit of such replacement
lender or lenders (or such agent) as if such Person or Persons were the original
Senior Banks hereunder).

         SECTION 6. WHEN PROCEEDS MUST BE PAID OVER. If any proceeds of Senior
Bank Collateral are received by Halifax or any Holder for application to the
Halifax Indebtedness other than as expressly permitted by the terms of this
Agreement, such proceeds shall be received by such Person in trust for the
benefit of Agent and Senior Banks and such Person shall promptly turn over such
proceeds to Agent (in the same form as received, with any necessary
endorsement), for application (in the case of cash) to, or as Senior Bank
Collateral (in the case of non-cash Property or securities) for, the payment or
prepayment of the Senior Indebtedness remaining unpaid to the extent necessary
to pay such Senior Indebtedness in full in cash in accordance with its terms. In
the event Halifax or any Holder fails to provide any endorsement, as
contemplated by the preceding sentences, Agent, or any of its officers or
employees, is hereby irrevocably authorized to make the same (which
authorization, being coupled with an interest, is irrevocable).

         SECTION 7. SUBROGATION. Halifax hereby waives all rights of subrogation
to the claims of Agent or any of the Senior Banks against any Credit Party, and
waives all rights of recourse to any security for any Senior Indebtedness, until
such time as all Senior Indebtedness shall have been indefeasibly paid in full
in cash and the Senior Credit Documents and all Senior Commitments thereunder
shall have terminated pursuant to the respective terms and provisions thereof;
PROVIDED that if any payment to Agent or any Senior Bank is rescinded as a
result of a Proceeding or otherwise, the subrogation of Halifax as provided
herein shall likewise be rescinded until all of the Senior Indebtedness is
indefeasibly paid in full in cash.

         SECTION 8. NO IMPAIRMENT OF SUBORDINATION. No right of Agent or any
Senior Bank to enforce the subordination of the Liens on Senior Bank Collateral
securing all or any part of the Halifax Indebtedness shall be impaired by any
act or failure to act by any Credit Party or by its failure to comply with this
Agreement. Without limiting the generality of the foregoing, the rights of Agent
and Senior Banks under this Agreement shall remain in full force and effect
without regard to, and shall not be impaired by: (a) any act or failure to act
of any Credit Party, Halifax or any other Holder, or any noncompliance by any
Credit Party, Halifax or any other Holder with any agreement or obligation,
regardless of any knowledge thereof which Agent or any Senior Bank may have or
with which Agent or any Senior Bank may be charged, (b) the validity or
enforceability of any of the Senior Credit Documents, (c) any extension or
indulgence in respect of any payment or prepayment of the Senior Indebtedness or
any part thereof or in respect of any other amount payable to Agent or any
Senior Bank, (d) any amendment, modification or waiver of any of the terms of
the Senior Credit Documents or the Halifax Documents, (e) any exercise, delayed
exercise or non-exercise by Agent or any Senior Bank of any right, power,
privilege or remedy under or in respect of any Senior Indebtedness, the Senior
Bank Collateral or this Agreement, (f) any other action of Agent or any Senior
Bank permitted under the Senior Credit Documents or this Agreement or (g) the
absence of any notice to, or knowledge by, Halifax or any other Holder of the
existence, creation or non-payment of all or any part of the Senior
Indebtedness, or the occurrence of any of the matters or events set forth in the
foregoing CLAUSES (a) through (f), except as such notice shall be specifically
required pursuant to the terms hereof.

         SECTION 9. WAIVERS AND CONSENTS OF HALIFAX.

existence or creation or non-payment of all or any part of the Senior
Indebtedness, (iii) all diligence in collection or protection of or realization

Lien or any Property subject thereto or exhaust any right or take any action
against any Credit Party or any other Person or any such Property, and (iv)
promptness, diligence, notice of acceptance and any other notice with respect to
any of the Senior Indebtedness.

         (b) Halifax agrees that Agent and Senior Banks may each, at any time
and from time to time, in their sole discretion, without the consent of or

Halifax or any other Holder, and without impairing or releasing the
subordination provided for herein or the obligations of Halifax or any other
Holder to Agent or any Senior Bank hereunder, amend, restate, supplement or
otherwise modify the Senior Credit Agreement or any of the other Senior Credit
Documents in any way whatsoever, including, without limitation, the following:
(i) shorten the final maturity of all or any part of the Senior Indebtedness,

Senior Indebtedness, (iii) increase the principal amount of Senior Indebtedness,

Indebtedness, (v) impose any additional fee or penalty upon any Credit Party or

Credit Documents, (vi) retain or obtain a Lien on any Property to secure any of
the Senior Indebtedness, (vii) enter into new Senior Credit Documents with any
Credit Party or any of its direct or indirect subsidiaries, (viii) change the

deal with any Property at any time pledged, assigned or mortgaged to secure or
otherwise securing all or any part of the Senior Indebtedness, (xiii) release

time received to the Senior Indebtedness in such manner such as such Person
shall determine and (xvii) otherwise manage and supervise the Senior
Indebtedness in accordance with such Person's usual practices, modified from
time to time as such Person deems appropriate under the circumstances.

         SECTION 10. REPRESENTATIONS AND WARRANTIES OF HALIFAX. Halifax hereby
represents and warrants to Agent and each Senior Bank that all material

bankruptcy or reorganization of any Credit Party, all as though such payment had
not been made.

         SECTION 14. SPECIFIC PERFORMANCE. Agent and each Senior Bank is hereby
authorized to demand specific performance of the provisions of this Agreement,
at any time when Halifax or any other Holder shall have failed to comply with
