              (iii) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
                    CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NORTH
                    CAROLINA.

     6.   Mandatory Prepayments. If an Event of Default under the Stock Pledge
          occurs, the principal and all accrued and unpaid interest on the
          Extension Note shall without further act become immediately due and
          payable in full.

          The following shall constitute "Prepayment Events"; (i) Purchaser or
          any of its subsidiaries shall incur any indebtedness for borrowed
          money, (other than under their respective working capital facilities
          (a "Debt Event"), (ii) Purchaser or any of its Subsidiaries shall
          issue any capital stock for cash (a "Stock Event"), or (iii) Purchaser
          or any of its Subsidiaries, shall sell any asset, other than in the
          ordinary course of business (an "Asset Sale"). "Net Proceeds" shall
          mean (i) in the case of a Debt Event, all cash loan proceeds, less
          reasonable transactions expenses, (ii) in the case of a Stock Event,
          all cash proceeds, less reasonable transaction expenses and (iii) in
          the case of an Asset Sale, all net cash proceeds, after payment of
          reasonable transactions expenses and indebtedness required to be
          repaid by any lien attached to the related asset, and, only in the
          case of a sale of the Pocono facility, the payment of indebtedness to
          Agro Power Development, Inc. related to the Pocono facility.
          "Available Net Proceeds" shall mean the excess of Net Proceeds over
          the amounts utilized to prepay the Note from Net Proceeds as required
          by Section 10 of the Stock Purchase Agreement.

          On the day that a Prepayment Event occurs, Purchaser shall pay over to
          Seller as a prepayment on the Extension Note, the lesser of the
          Available Net Proceeds related to such Prepayment Event and the
          principal and interest the outstanding on the Extension Note. Amounts
          received by Seller shall be applied first against accrued interest and
          the balance against the remaining principal outstanding. If any such
          payment shall be sufficient to pay the Extension Note in full, Seller
          shall on receipt of such payment, mark the Extension Note as cancelled
          and return the same to Purchaser. If such payment is not sufficient to
          pay the Extension Note in full, Seller shall, on receipt of a new
          Extension Note, in the form of Exhibit B in a principal amount equal
          to the outstanding principal after such payment, surrender to
          Purchaser the Extension Note then held by Seller.
