       1. BOA hereby consents to the FINOVA Lease Transaction and to the
exercise of FINOVA's rights under the agreements, instruments and documents
executed in connection therewith.

       2. Notwithstanding the provisions of applicable law with respect to the

liens, security interests and other interests held by BOA in and to the FINOVA
Equipment, to the interest of FINOVA (the "FINOVA Interest") in and to the
FINOVA Equipment, which FINOVA Interest shall be senior and superior to those
held by BOA in and to the FINOVA Equipment.

and shall be promptly paid and delivered by BOA to FINOVA in the same form

under any state or federal bankruptcy or insolvency law.

       6. This Agreement is intended solely to establish the respective rights
as between FINOVA and BOA; shall not in any way affect or impair the validity or
enforceability of their respective security interests as against any other
person or entity; and no such other person or entity (whether a trustee in
bankruptcy or otherwise) shall have any rights or benefits hereunder.

       7. BOA acknowledges that Borrower is not in default or breach of any
provision contained in any agreement and the consummation and execution of the
FINOVA Lease Transaction will not be a breach or default under any such
agreement.

       8. THIS AGREEMENT SHALL BE BINDING UPON THE SUCCESSORS AND ASSIGNS OF THE
