Tenant shall not permit any mechanic’s, materialmen’s or other liens (each, a “ Lien ”) to be filed against the Building, the Premises or Tenant’s leasehold interest therein. Tenant, at its sole expense, or at the expense of Subtenant if such Lien arises as the result of materials or labor furnished for or on behalf of Subtenant, shall cause any such Lien to be released or shall obtain a surety bond in the minimum amount required by law to discharge any such Lien in accordance with the provisions in Article 15 of the OCOM Sublease. If Tenant fails to cause any such Lien to be so released or bonded within thirty (30) days after Tenant’s receipt of notice thereof, Landlord, without waiving its rights and remedies based on such failure, may cause such Lien to be released by any means Landlord reasonably deems proper, including payment in satisfaction of any claim giving rise to such Lien. Tenant shall pay or shall cause Subtenant to pay to Landlord as Additional Rent, within thirty (30) days after Tenant’s receipt of an invoice from Landlord, any sum paid by Landlord to remove any such Lien, together with interest at the rate prescribed herein from the date of such payment by Landlord until paid by Tenant. Tenant shall have the right to contest any such Lien in good faith provided that Tenant provides reasonable security in connection therewith. Notice is hereby given that Landlord shall not be liable or responsible to persons who furnish materials or labor for or in connection with the Premises or the Building on behalf of Tenant, and Landlord shall have the right at all reasonable times to post on the Premises or the Building and record any notices of non-responsibility which it deems necessary for protection from such Liens.
