         2.       Purchase and Sale of Contracts.

                  A.       Subject to the terms and conditions set forth in

         assign, transfer and deliver to Buyer, without recourse, all of
         Seller's right, title and interest in the Contracts described in the
         Schedule of Contracts, in exchange for payment by Buyer to Seller of
         the Purchase Price. Buyer agrees to accept from Seller as of the
         Closing Date, all of Seller's right title, and interest in the
         Contracts without recourse to Seller. Seller and Buyer intend that the
         sale of the Contracts will constitute a sale of each Contract.

                  B.       On the Closing Date, Buyer agrees to pay Seller the

         parties. The consideration payable by Buyer to Seller for the Contracts
         constitutes reasonably equivalent value and fair consideration for the
         Contracts and such consideration is based on terms consistent with an
         arms-length transaction.

                  C.       All sales, transfer, documentary stamp, recording
         and other similar taxes and/or fees which may be due or payable in
         conjunction with this sale shall be borne by, Seller. Buyer will be
         responsible for any expense related to change of lien holder.

         the respective hazard insurance policy for each Contract, which
         notification may accompany or be included in Seller's letters

         and delivered, this Agreement will constitute the legal, valid and
         binding obligation of the Seller, enforceable in accordance with the
         terms, except as enforcement of such terms may be limited by
         Bankruptcy, insolvency, or similar laws affecting the enforcement of
         creditor's rights generally and by the availability of equitable

                  C.       Litigation.  No litigation or administrative
         proceeding of or before any court or governmental body is currently
         pending, or to the knowledge of Seller threatened, against Seller or

         mutually agree, and in all instances in a timely manner in accordance
         with the terms of this Agreement.

                  E.       No Violations.  The execution, delivery and
         performance of this Agreement by the Seller will not violate any
         provision of any existing law or regulation, or any other decree of any
         court applicable to the Seller or the charter or bylaws of the Seller,
         or constitute a material breach of any mortgage, indenture, contract or
         other agreement to which the Seller is a party, or by which the Seller
         may be bound.

         5.       Representations and Warranties with Respect to Contracts.

                  D.       Acceptability of Investment. Seller is unaware of

represents and warrants to Seller, as of the Closing Date as follows:

         performed by it under this Agreement, and has taken all necessary
         corporate action to authorize the execution, delivery and performance
         of this Agreement. When executed, and delivered, this Agreement will
         constitute the legal, valid and binding obligation of the Buyer,
         enforceable in accordance with the terms, except as enforcement of such

         affecting the enforcement of creditor's rights generally and by the
         availability of equitable remedies.

                  C.       No Violations.  The execution, delivery and
         performance of this Agreement by Buyer will not violate any provision
         of any existing law or regulation, or any other decree of any court
         applicable to the Buyer or the certificate or partnership
