Hazardous Materials. Tenant fails to perform or breaches any agreement or covenant to be performed or observed by Tenant under Paragraph 4.4 above and such failure or breach continues for more than ten (10) days after Landlord gives written notice thereof to Tenant; provided, however, that if, by the nature of such agreement or covenant, such failure or breach cannot reasonably be cured within such period of ten (10) days, an Event of Default shall not exist as long as Tenant commences the curing of such failure or breach within such period of ten (10) days and, having so commenced, thereafter prosecutes such cure with diligence and dispatch to completion as soon as may be reasonably practicable thereafter.

Tenant shall not cause or permit any Hazardous Materials (as defined below) to be brought upon, kept or used in or about the Premises, the Building or the Project in violation of Applicable Laws by Tenant or any of its employees, agents, contractors or invitees (collectively with Tenant, each a “Tenant Party”). If # Tenant breaches such obligation, # the presence of Hazardous Materials as a result of such a breach results in contamination of the Project, any portion thereof, or any adjacent property, # contamination of the Premises otherwise occurs during the Term or any extension or renewal hereof or any holding over by Tenant hereunder or # contamination of the Project occurs as a result of Hazardous Materials that are placed on or under or are released into the Project by a Tenant Party, then Tenant shall Indemnify the Landlord Indemnitees from and against any and all Claims of any kind or nature, including # diminution in value of the Project or any portion thereof, # damages for the loss or restriction on use of rentable or usable space or of any amenity of the Project, # damages arising from any adverse impact on marketing of space in the Project or any portion thereof and # sums paid in settlement of Claims that arise before, during or after the Term as a result of such breach or contamination. This Indemnification by Tenant includes costs incurred in connection with any investigation of site conditions or any clean-up, remedial, removal or restoration work required by any Governmental Authority because of Hazardous Materials present in the air, soil or groundwater above, on, under or about the Project. Without limiting the foregoing, if the presence of any Hazardous Materials in, on, under or about the Project, any portion thereof or any adjacent property caused or permitted by any Tenant Party results in any contamination of the Project, any portion thereof or any adjacent property, then Tenant shall promptly take all actions at its sole cost and expense as are necessary to return the Project, any portion thereof or any adjacent property to its respective condition existing prior to the time of such contamination; provided that Landlord’s written approval of such action shall first be obtained, which approval Landlord shall not unreasonably withhold; and provided, further, that it shall be reasonable for Landlord to withhold its consent if such actions could have a material adverse long-term or short-term effect on the Project, any portion thereof or any adjacent property. Tenant’s obligations under this Section shall not be affected, reduced or limited by any limitation on the amount or type of damages, compensation or benefits payable by or for Tenant under workers’ compensation acts, disability benefit acts, employee benefit acts or similar legislation. Notwithstanding the foregoing, Landlord shall Indemnify the Tenant Parties from and against any and all Claims arising from the presence of Hazardous Materials at the Project in violation of Applicable Laws as of the Execution Date, unless placed at the Project by a Tenant Party.
