Dear Mr. Alsentzer:

We are writing this letter to confirm our agreement (the "Agreement") that U.S.
Plastic Lumber Corp. et al. (the "Debtors" or the "Company") in the Chapter 11

involving the Company, assisting the Company in a developing and negotiating a
plan of reorganization with its creditors, selling the Company's assets, and/or
raising additional debt/equity capital for the Company, providing turnaround and
crisis management services, and any other tasks that may be requested by the
Company. Triax shall provide the Company with the services of Joseph Sarachek to
serve as Chief Restructuring Officer and at least one additional professional to
work for the Company as set forth below.

This Agreement shall become effective as of July 23, 2004 upon the execution
hereof by both the Company and Triax and approval of the Bankruptcy Court and
shall terminate at any time after thirty (30 days) upon reasonable notice by the
Company or Triax, subject to Bankruptcy Court approval. This agreement shall
supercede any previous agreements executed by the Company. Neither termination

Triax up to the date of termination; b) any compensation which Triax is
otherwise entitled to hereunder; c) the reimbursement of expenses incurred by
Triax up to the date of termination; d) the attached indemnification provisions,
which are incorporated herein, all of which shall remain in full force and

provisions of the Bankruptcy Code and Rules:

I.    The Company shall pay Triax an hourly fee of $375 for senior
      professionals, $250 for junior professionals and $100 for associates
      ("Hourly Fee"), beginning July 23, 2004 with a monthly maximum
      compensation on hourly fees of $75,000 per month.

                                                        U.S. Plastic LumberCorp.

II.   In addition to the Hourly Fee, the Company shall pay Triax a Transaction
      Fee (the "Transaction Fee"), which is contingent upon the consummation of
      a sale or sales of assets, a refinancing or repurchase of the secured
      debt, or any other financial restructuring which provides aggregate gross
      proceeds (whether in cash or other-in-kind consideration, including
      assumption and forgiveness of debt ) as follows:

</TABLE>

III.  In addition to the Hourly Fee and Transaction Fee, the Company shall pay
      Triax a Financing Fee (the "Financing Fee") of 1% of the aggregate amount
      of any Financing, whether it be DIP Financing or exit financing committed
      to the Company. The Financing Fee shall be paid out of the proceeds of any
      Financing.

IV.   Triax shall be reimbursed for all reasonable out-of-pocket expenses
      incurred in carrying out the terms of this Agreement, including telephone,
      travel, facsimile, courier, computer time charges and attorneys' fees (to
      the extent necessary), food, messenger services, postage and copying.

V.    The Transaction Fee and any accrued Hourly Fees that are due and owing,
      shall be paid upon the earlier of i) a plan of reorganization is
      confirmed, ii) a sale of, a portion or, substantially all of the assets;
      or iii) a financing which provides that AMPAC Capital Solutions, LLC. is
      no longer providing debtor in possession financing to the Company; iv) a
      Trustee is appointed or the Company's cases are converted to Chapter 7;
      and v) Triax's services have been terminated pursuant to this agreement.

All compensation and reimbursement of expenses are subject to prior approval of
the Bankruptcy Court in accordance with sections 330 and 331 of the Bankruptcy
Code. Triax agrees to include in its application for approval of compensation a
narrative of services performed and will, to the best of its ability, include
the time spent in connection with such services performed. The Debtors will seek
an order from the Bankruptcy Court to have the non-accrued portion of the Hourly
Fees of Triax be paid on a monthly basis. Payment of all fees and expenses
incurred under this Agreement, are solely the responsibility of the Company,
however Triax shall be granted a carve-out for its professional fees from the
secured claim of APFC. For a period of six months following termination of this
Agreement, Triax shall be entitled to receive the Transaction Fee and Financing
Fee in the event the Company or its successors consummate a Transaction or a
Financing with any party with whom Triax or the Company have contacted during
the term of this Agreement.

time for meetings, conferences, preparation and travel, and all related costs
and expenses, including the reasonable legal fees and expenses of Triax's
counsel.

without release thereof by Triax.

Responsibility for Assignment/Obligations of Triax Solely to the Company

The services herein provided are to be rendered solely to the Company. They are
not being rendered by Triax as an agent or as a fiduciary of the shareholders of
the Company and Triax shall not have any liability or obligation with respect to
its services hereunder to such shareholders or any other person, firm or
corporation other than the Company.

Triax will not be responsible for independently verifying the accuracy of any

                            INDEMNIFICATION AGREEMENT

Appendix A to Letter Engagement Agreement (the "Agreement"), dated June 7, 2005
by and between U.S. Plastic Lumber Corp. and its subsidiaries, affiliates and
related entities (the "Company") and Triax Capital Advisors, LLC ("Triax").

The Company agrees to indemnify and hold Triax and its affiliates, control
persons, directors, officers, employees and agents (each an "Indemnified
Person") harmless from and against all losses, claims, damages, liabilities,
costs or expenses, including those resulting from any threatened or pending
investigation, action, proceeding or dispute whether or not Triax or any such
other Indemnified Person is a party to such investigation, action, proceeding or
dispute, arising out of Triax's entering into or performing services under this
Agreement, or arising out of any matter referred to in this Agreement. This
indemnity shall also include Triax's and/or any such other Indemnified Person's
reasonable attorneys' and accountants' fees and out-of-pocket expenses incurred
in, and the cost of Triax's personnel whose time is spent in connection with,
such investigations, actions, proceedings or disputes which fees, expenses and
costs shall be periodically reimbursed to Triax and/or to any such other
Indemnified Person by the Company as they are incurred; provided, however, that
in no event shall Triax and its affiliates, control persons, directors,
officers, employees and agents be indemnified in the case of its or their own
bad-faith, self-dealing, breach of fiduciary duty, gross negligence, reckless or
willful misconduct or malpractice arising from the foregoing (except ordinary
negligence). A court of competent jurisdiction shall make such a determination,
(but pending any such final determination the indemnification and reimbursement
provisions hereinabove set forth shall apply and the Company shall perform its
obligations hereunder to reimburse Triax and/or each such other Indemnified
Person as described herein). In no event shall Triax, its affiliates, control
persons, directors, officers, employees or agents be indemnified if the Company
asserts a claim for, and a court determines by final order that such claim arose
out of Triax, its affiliates, control persons, directors, officers, employees or
agents own bad-faith, self-dealing, breach of fiduciary duty, gross negligence,
reckless or willful misconduct or malpractice arising from the foregoing (except
ordinary negligence).

The Company also agree that no Indemnified Person shall have any liability
(whether direct or indirect, in contract or tort or otherwise) to the Company
for or in connection with any act or omission to act as a result of its
engagement under this Agreement except for any such liability for losses,
claims, damages, liabilities or expenses incurred by the Company that is found
in a final determination by a court of competent jurisdiction to have resulted
from Triax, its affiliates, control persons, directors, officers, employees or
agents own bad-faith, self-dealing, breach of fiduciary duty, gross negligence,
reckless or willful misconduct or malpractice arising from the foregoing (except
ordinary negligence).

If for any reason, the foregoing indemnification is unavailable to Triax or any
such other Indemnified Person or insufficient to hold it harmless, then the
Company shall contribute to the amount paid or payable by Triax or any such
other Indemnified Person as a result of such loss, claim, damage or liability in
such proportion as is appropriate to reflect not only the relative benefits
received by the Company on the one hand and Triax or any such other Indemnified
Person on the other hand, but also the relative fault of the Company and Triax
or any such other Indemnified Person, as well as any relevant equitable
considerations; provided that in no event

will the aggregate contribution by Triax and any such other Indemnified Person
hereunder exceed the amount of fees actually received by Triax pursuant to this
Agreement. The reimbursement, indemnity and contribution obligations of the
Company hereinabove set forth shall be in addition to any liability which the
Company may otherwise have and these obligations and the other provisions
hereinabove set forth shall be binding upon and inure to the benefit of any
successors, assigns, heirs and personal representatives of the Company, Triax
and any other Indemnified Person.

Nothing herein shall be construed to impose any liability on any officers,
directors or shareholders of the Company.

The terms and conditions hereinabove set forth in this Appendix A. shall survive
the termination and expiration of this Agreement and shall continue indefinitely
thereafter.

agreement, indebtedness, lease, encumbrance, commitment, license, franchise,
permit, authorization or concession to which

                                       7
<PAGE>

Purchaser is a party or by which the Purchaser is bound, which breach of default
would have a material adverse effect on the business or financial condition of
Purchaser or its ability to Order or award, which violation would have a
material adverse effect on the business or financial condition of Purchaser or
its ability to consummate the Transaction.

            d.    Consents and Approvals. No consent, approval or authorization
of, or declaration, filing or registration with, any Governmental Authority, or

may, within five (5) days after receipt of such notice, at Purchaser's option,
notify Seller of termination of this Agreement in which case Stichter shall
return the Deposit to Purchaser and this Agreement shall thereafter be null and
void. If Purchaser does not so terminate this Agreement, the Closing shall occur
with no diminution of the Purchase Price, and Purchaser shall be entitled to
receive, at Closing, all insurance proceeds resulting therefrom which are
payable either before or after Closing (less any amounts Seller may have paid in
repairing or restoring the Property).

                  ii.   Risk of Loss by Condemnation. The risk of condemnation
of the Property prior to the Closing shall be on Seller. If such condemnation

      19.   Termination. This Agreement may be terminated, and the Transaction
may be abandoned: (i) at any time before the Closing, by mutual written
agreement of Seller and Purchaser; (ii) at any time before the Closing, by
Seller and Purchaser, in the event that the Final Order cannot be obtained or
any other final, nonappealable order or any law becomes effective restraining,
enjoining or otherwise prohibiting or making illegal the consummation of the
Transaction upon notification of the non-terminating party by the terminating
party; (iii) by Purchaser as provided in Section 4(b); (iv) by Seller as
provided in Section 21b; (v) by Purchaser pursuant to Sections 15(e), 18(c)(i)
and 18(c)(ii); (vi) as provided in Paragraph 15f, (vii) by Seller in the event
Purchaser fails to post the Increased Deposit by January 12, 2005 pursuant to
Paragraph 3a, and (viii) by February 28, 2005 in the event the Final Order has
not been obtained by said date.

      20.   Effect of Termination. If this Agreement is terminated pursuant to
Section 19, this Agreement will forthwith become null and void and (i) there

or affiliates); and (ii) the Deposit shall be paid to Purchaser.

      21.   Failure to Close.

            a.    Seller Default. If the Closing shall not have occurred due to
Seller's default hereunder and this Agreement shall not have been terminated
pursuant to Section 19, Purchaser will be entitled, at its election and its sole
and exclusive remedy, either (a) to receive the return of the Deposit or (b) to
enforce specific performance of this Agreement. The foregoing remedies or the
sole remedies granted to Purchaser in the event Closing does not occur due to
Seller's default hereunder, and the Purchaser hereby waives any additional or
other rights or remedies to which Purchaser might otherwise be entitled.

            b.    Purchaser Default; Liquidated Damages. If the Closing shall
not have occurred due to Purchaser's default hereunder, Seller will be entitled,
at its election and as its sole and exclusive remedy, either (a) to receive the
Deposit as liquidated damages and thereupon

                                       11
<PAGE>

terminate this Agreement or (b) to enforce specific performance of this
Agreement. The foregoing remedies are the sole remedies granted to Seller in the
event the Closing does not occur due to Purchaser's default hereunder, and
Seller hereby waives any additional or other rights or remedies to which Seller
might otherwise be entitled. The parties acknowledge that Seller's actual
damages, in the event of a failure to consummate the Transaction due to
Purchaser's default, would be extremely difficult or impracticable to determine.
After negotiation, the parties have agreed that, considering all the
circumstances existing on the Effective Date, the amount of the Deposit is a
reasonable estimate of the damages that Seller would incur in such event.

      22.   Dispute Resolution Procedures. Either party may require that any
controversy, claim or dispute arising out of the terms of this Agreement shall
be submitted for resolution to the Bankruptcy Court.

      24.   Overbid and Breakup Fee. Subject to approval by the Bankruptcy Court
any interested third party may offer to buy the Property on similar terms and
conditions described herein; provided, however, any third party purchaser must
offer a purchase price greater than that which Purchaser has proposed to pay
Seller pursuant to the terms hereof. In such event the offer to purchase
("Overbid Offer") must (i) be in writing signed by the third party offeror; (ii)
be for a cash purchase price of at least THIRTY-TWO THOUSAND FIVE HUNDRED
DOLLARS ($32,500.00) more than the Purchase Price to be paid by Purchase (the
"Initial Overbid") (iii) be accompanied by a ONE HUNDRED FIFTY THOUSAND DOLLARS
($150,000.00) deposit by way of cashier's check or certified funds; (iv) be
delivered to counsel for Seller at least three (3) business days prior to the
date of the hearing to approve the sale; and (v) be delivered to Purchaser
concurrent with the delivery of the Overbid Offer to counsel for Seller. In the
event the Real Property is sold to a third party purchaser, any funds deposited
by Purchaser, including but not limited to, the Deposit, shall promptly be
returned to Purchaser and Seller shall be required to immediately pay to
Purchaser the additional sum of one percent (1%) of the Purchase Price to
compensate Purchaser for its out-of-pocket expenses, reasonable attorneys' fees
and related costs. Seller shall seek Bankruptcy Court approval of such overbid
procedures in advance of the hearing on any sale motion.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the Effective
Date.
