      3. Disposal Fees.

            3.01 GreenMan shall pay PRR disposal fees of $15.44 per Ton for the
disposal of Waste at the Landfills, inclusive of federal, state and local taxes,
fees or assessments that are levied on PRR with respect to the acceptance and
disposal of such Waste; provided, however, that PRR shall provide to GreenMan
credit for disposal fees equal to $10,000.00; and provided further that any
documented increase over the current level of federal, state and local taxes,
fees or assessments that are currently levied on PRR with respect to the
acceptance and disposal of such Waste during the term of this Agreement shall be
payable by GreenMan in addition to the disposal fees specified herein.

            3.02 Should this Agreement be extended beyond the Initial Term, the
fees provided for in Section 3.01 shall be renegotiated by the parties upon the
expiration of the Initial Term, or any extension thereof, of this Agreement.

            3.03 If PRR performs disposal services outside Regular Business
Hours or any additional services, PRR may adjust the disposal fees to offset the
additional costs in performing such services.

            3.04 PRR shall send GreenMan a monthly invoice for the disposal fees
incurred during the previous month. GreenMan shall pay PRR the full amount
within thirty (30) days of receipt of the invoice. Unpaid invoices shall carry
interest at the rate of one and one half percent (1.5%) per month. The
obligations of GreenMan to pay the disposal fees and other amounts payable
hereunder shall be absolute and unconditional. In the event that GreenMan fails
to timely pay any outstanding amount, PRR may, in addition to any other remedies
available to PRR, terminate this Agreement by giving 15 days written notice to
GreenMan. GreenMan may cure by making full payment within the 15 day period
after receipt of notice.

            3.05 In the event that (i) any Waste requires special handling or
management due to its composition or volume, or (ii) PRR agrees to dispose of
any Unacceptable Waste, GreenMan and PRR shall determine in advance, on a case
by case basis, the charge to GreenMan for PRR's disposal of such wastes. Payment
for such disposal shall be upon the same terms as the payment of other disposal
fees. The parties hereto agree that scrap residual generated by tire processing
activities and sheared pieces of "off-the-road" tires shall not be considered
Unacceptable Waste or Waste requiring special handling or management.

      4. Delivery and Acceptance of Waste.

            4.01 GreenMan agrees to deliver to the Landfill only Waste generated
at and residing at the Lawrenceville Site. PRR represents and warrants that
there is no Unacceptable Waste located at the Lawrenceville Site as of the date
of this Agreement. GreenMan also agrees that it will offer to deliver to PRR any
Waste generated by any other site operated by GreenMan in the state of Georgia

disposal fees for such Waste shall not exceed the amount set forth in Section
3.01 hereof.

            4.02 PRR shall have the right to weigh all vehicles delivering Waste
to the Landfill. At any time, PRR may confirm the tare weight of any vehicle
delivering Waste to the Landfill by or on behalf of GreenMan.

            4.03 GreenMan acknowledges that PRR intends to reject waste that, in
PRR's reasonable determination, would be in violation of the Landfills' then
existing licenses or permits or would result in a violation of applicable
federal, state or local laws, regulations or ordinances. The foregoing
notwithstanding, PRR agrees that it will not reject any Waste from the
Lawrenceville Site that existed prior to the date of this Agreement.

            4.04 Ownership of Waste delivered to the Landfill by or on behalf of
GreenMan shall pass to and be accepted by PRR when the vehicle transporting the
Waste is fully unloaded at the Landfill. Ownership of Unacceptable Waste
delivered to the Landfill by or on behalf of GreenMan shall not pass to PRR at
any time unless PRR agrees in advance to accept such Unacceptable Waste.

            4.05 PRR may detain and inspect the contents of all vehicles owned
or operated by GreenMan that are delivering Waste to the Landfill. GreenMan
agrees to monitor and inspect on a regular basis the contents of its vehicles in
order to ensure that the Waste being delivered to the Landfill contains no
Unacceptable Waste.

            4.06 GreenMan shall not deliver any Unacceptable Waste to the
Landfill. If any Unacceptable Waste is delivered by or on behalf of GreenMan,
PRR shall have the right to refuse or reject such waste, or, if not detected
prior to acceptance at the Landfill, PRR may remove such waste and assure its
proper disposal, all at GreenMan's expense, which expense GreenMan agrees to
promptly pay upon presentation by PRR of an invoice setting forth the costs in
reasonable detail.

            4.07 In addition to other remedies provided in this Agreement, PRR
may terminate this Agreement upon repeated deliveries or the one-time
intentional delivery of Unacceptable Waste by GreenMan. PRR shall notify
GreenMan in writing of its intention to terminate, and termination shall become
effective within 15 days of receipt.

            4.08 PRR shall not be responsible for the transportation of Waste to
the Landfill. PRR shall not be responsible for the transportation or redelivery
to GreenMan, or elsewhere, of any waste, including without limitation
Unacceptable Waste to the Landfill by or on behalf of GreenMan.

      5. Termination. PRR may terminate this Agreement upon (i) any breach or
default of this Agreement by GreenMan or (ii) an event of Force Majeure that
continues unabated for a period of sixty (60) days and renders PRR unable,
wholly or in part, to carry out any of its obligations under this Agreement.

      6. Representations and Warranties of GreenMan. GreenMan represents and

into and to fully and timely perform its obligations under this Agreement;
