16. DAMAGE BY CASUALTY. (a) If, during the Term or previous thereto, the Premises or the building of which said Premises are a part shall be destroyed or so damaged by fire or other casualty as to become untenantable, then in such event, at the option of Lessor, this Lease shall terminate from the date of such damage or destruction. Lessor shall exercise this option to so terminate this Lease by notice in writing delivered to Lessee within thirty (30) days after such damage or destruction. Upon such notice, Lessee shall immediately surrender said Premises and all interest therein to Lessor, and Lessee shall pay rent only to the time of such damage or destruction. If Lessor does not elect to terminate this Lease, this Lease shall continue in full force and effect, and Lessor shall expeditiously repair the Premises, placing the same in as good a condition as they were at the time of the damage or destruction, and for that purpose, may enter said Premises. In that event rent shall abate in proportion to the extent and duration of untenantability. In either event, Lessee shall remove all rubbish, debris, merchandise, furniture, equipment and its other personal property within five days after the request by Lessor. (b) If the Premises shall be slightly damaged by fire or other casualty, so as not to render the same untenantable, then Lessor shall expeditiously repair the same and in that case the rent shall not abate. Except for rent abatement as herein provided, no compensation or claim shall be made by or allowed to Lessee by reason of any inconvenience or loss of business arising from the necessity of repairing any portion of the building or the Premises.
