are obtained and insurance on the Aircraft is made valid.

     Lessee will not directly or indirectly create, incur, assume or suffer to
exist any lien on or with respect to the Aircraft.  Lessee will promptly, at its
own expense, take such

all salvage from broken or worn out parts. The workmen who inspect, maintain,
and repair the Aircraft on Lessee's behalf shall not be employees of Lessor, but
