apply all or any part of any Security Deposit to cure any default of Lessee
under the Lease. If upon final termination of this Schedule, Lessee has
fulfilled all of the terms and conditions hereof, then Lessor shall pay to
Lessee upon Lessee's written request any remaining balance of the Security
Deposit for this Schedule, without interest.

7.  TITLE TO EQUIPMENT; FIRST PRIORITY LIEN. Lessee represents, warrants and
agrees: that Lessee currently is the lawful owner of the Equipment; that good
and marketable title to the Equipment shall remain with Lessee at all times;
that Lessee has granted to Lessor a first priority security interest in the
Equipment and all Proceeds; and that the Equipment and all Proceeds are, and at
all times shall be, free and clear of any Liens other than Lessor's security
interest therein. Lessee at its sole expense will protect and defend Lessor's
first priority security interest in the Equipment against all claims and demands
whatsoever.

8.  CERTAIN DEFINITIONS. "Secured Obligations" means (a) all payments and other
obligations of Lessee under or in connection with this Schedule, and (b) all
payments and other obligations of Lessee (whether now existing or hereafter
incurred) under or in connection with the Master Lease and all present and

liabilities and/or obligations of any kind (whether now existing or hereafter
incurred, absolute or contingent, direct or indirect) of Lessee to Lessor or to
