Fire and Other Casualty In the event that at any time during the term hereof (including any extended term) the Leased Premises are totally damaged or destroyed by fire or other casualty or substantially damaged so as to render them or a material portion thereof untenantable, then there shall be a just and proportionate abatement of the Rent payable hereunder until the Leased Premises are made suitable for Tenant’s occupancy, and the Lease Term shall be extended, without the necessity of further action by any party, for a period equal to the time during which Rent so abated. In the event of such substantial (or total) damage to the Leased Premises, Landlord shall proceed at its expense and with reasonable diligence to repair and restore the Leased Premises to substantially the same condition they were in immediately prior to such casualty. Notwithstanding the foregoing, if Landlord in its sole discretion determines that timely restoration is not possible or practical or that there are or will be insufficient insurance proceeds available to Landlord to accomplish same, then Landlord shall have the right to terminate this Lease by written notice given to Tenant within ninety (90) days after the occurrence of such casualty. If Landlord proceeds with the repair and restoration of the Leased Premises, in the event the Leased Premises have not been restored to a condition substantially suitable for their intended purpose within one hundred eighty (180) days following said casualty, then either Landlord or Tenant shall have the right to terminate this Lease by giving notice thereof to the other party within thirty (30) days after the expiration of such period (as so extended) provided that such restoration is not completed within such period. This Lease shall cease and come to an end without further liability or obligation on the part of either party thirty (30) days after such giving of notice unless within such thirty-day period Landlord substantially completes such restoration. Such right of termination shall be Tenant’s sole and exclusive remedy at law or in equity for Landlord’s failure so to complete such restoration, and time shall be of the essence with respect thereto.
