connection with the bankruptcy of the Tenant.

     f.   A failure to vacate the Premises upon termination of this Lease.

No payment by Tenant or receipt by Landlord of an amount less than the required
payment set forth to the Lease, shall be considered as anything other than a
partial payment of the amount due.  No endorsement or statement to the contrary

Tenant to the possession of the Premises shall immediately terminate, and the

termination of this Lease, to which event Landlord shall have the right to relet
the Premises as the agent for the Tenant and to hold the Tenant responsible for

entry or repossession by the Landlord shall serve to terminate this Lease,
unless the Landlord so elects in writing, nor shall it release Tenant from any
liability for the payment at any rent stipulated to be paid pursuant to this
Lease or for the performance or fulfillment of any other term or condition
provided herein.

     c.   Landlord may declare all the installments of rent for the whole term
of this lease to be immediately due and payable at once without further demand,

date of default at the highest rate permitted by law.

     d.   Landlord shall have the right to take no immediate action and to hold
the Tenant responsible for the rent as it becomes due.

     e.   Any Base Minimum Rent which was abated or waived by Landlord shall
also be immediately due and payable by Tenant to Landlord.

     f.   In the event of a holdover by Tenant after the termination of this
Lease, Landlord shall have the right to collect double (200%) the amount of Base
Minimum Rent. In addition, Tenant shall be responsible for any cost or expenses
incurred by Landlord as a result of such holdover, including but not limited to
