Tenant shall not permit mechanic's or other liens to be placed upon the Property, Building, Premises or Tenant's leasehold interest in connection with any work or service done or purportedly done by or for the benefit of Tenant, including without limitation the Tenant Work and any Alteration. If a lien is so placed, Tenant shall, within 20 days of demand from Landlord, fully discharge the lien by settling the claim which resulted in the lien or by bonding or insuring over the lien in the manner prescribed by the applicable lien Law. If Tenant fails to discharge the lien within such 20 days, then, in addition to any other right or remedy of Landlord, Landlord may bond or insure over the lien or otherwise discharge the lien. Tenant shall, within 30 days after receipt of an invoice from Landlord, reimburse Landlord for any amount paid by Landlord, including reasonable attorneys' fees, to bond or insure over the lien or discharge the lien.
