            (the "Joint Written Direction"), substantially in the form attached

            Cents ($3,789,474) of the Tranche C Loan (as defined in the Term

            Supplier a participation agreement in substantially the form
            attached hereto as Exhibit F (the "Participation Agreement")
            evidencing the Supplier's Participation and Supplier hereby agrees
            to execute and deliver the Participation Agreement to RBC together

            Supplier in accordance with the Joint Written Direction in partial
            satisfaction of the amounts owing for the Pre-Petition Work.

            balance of the amounts owing for the Pre-Petition Work shall be
            extinguished on the Effective Date. Supplier acknowledges that
            Purchaser has submitted the Term Sheet to Supplier together with a
            draft of the CIM and that Supplier has had sufficient time to review
            the Term Sheet and the CIM. The final terms of the Term Loan
            Agreement shall be substantially consistent with the Term Sheet.

                  (2) Post-Petition Work. The price for the Work to be performed

            Twenty-Three Thousand Nine Hundred Forty-Five Dollars and 28/100

            certain Post-Petition Work performed by Supplier subsequent to the
            Filing Date. On the Funding Date, Purchaser shall deposit Ninety Six
            Thousand Forty-Two Dollars and 49/100 Cents ($96,042.49) (the
            "Post-Petition Partial Payment

            Amount") with the Escrow Agent to be held and released in accordance
            with the terms of the Joint Written Direction. The Escrow Agent
            shall release the Post-Petition Partial Payment Amount to Supplier
            in accordance with the Joint Written Direction on account of the
            remainder of the amounts owing from Purchaser to Supplier on account
            of certain Post-Petition Work that was performed by Supplier
            subsequent to the Filing Date. The remaining Post-Petition Price of
            Two Million Four Hundred Seventy-Nine Thousand Four Hundred
            Sixty-Eight Dollars and 54/100 Cents ($2,479,468.54) (which
            represents the balance of the Post-Petition Work to be performed by
            Supplier subsequent to the Filing Date) shall be paid to Supplier
            (subject to Supplier's rights explicitly set forth herein to
            withhold amounts) in installments within thirty (30) days from each
            date that Supplier submits an invoice to Purchaser with five percent
            (5%) of the amount of each invoice retained (the "Retainage") by
            Purchaser to secure Supplier's obligations hereunder. Each invoice
            submitted by Supplier to Purchaser for Post-Petition Work shall
            describe and set forth all Work milestones achieved or reached
            according to the schedule attached hereto as Exhibit B (the "Project
            Schedule") and the sum of all prior payments made by Purchaser to
            Supplier through the last day of the previous month. Invoices for
            the Post-Petition Work shall be submitted by Supplier to Purchaser
            no more often than once a month.

                  (3) Release of Retainage. The Retainage shall be released to
            Supplier on the earlier of (a) thirty (30) days after Final
            Acceptance, (b) ninety (90) days after the later of (i) the final
            shipment of all of the Equipment (other than minor items of the
            Equipment that do not affect the performance or safe and continuous
            operation of the Project), and (ii) the completion of the field
            machining of Purchaser's mill housings, and (c) June 1, 2004 if
            Final Acceptance has not occurred prior to such date through no
            fault of Supplier. Supplier acknowledges and agrees that in the
            event amounts are owing from Supplier to Purchaser as a result of a
            breach or default by Supplier hereunder or the failure of Supplier
            to otherwise fulfill any of its obligations and agreements
            hereunder, Purchaser shall have the right to retain such reasonable
            amounts from the Retainage prior to releasing the Retainage to
            Supplier."
