Landlord shall not be required to, but Tenant, unless otherwise agreed by Landlord, may with due dispatch replace or restore forthwith any trade fixture, signs, or other installations theretofore installed by Tenant. Basic Rent payable under this Sublease shall be abated if such fire or other insurable casualty renders the Original Building unusable by Tenant, but if any such casualty is caused by the fault of Tenant, there shall be no abatement of rent. Such abatement shall continue for the period commencing with such casualty and ending with the completion by Landlord of such work or repair and/or reconstruction as Landlord is obligated to do. If, however, the Original Building shall be damaged or destroyed by any cause so that the Landlord shall decide to demolish or abandon, or completely rebuild it, Landlord may, within sixty (60) days after such damage or destruction, give Tenant written notice of such decision, and thereupon this Sublease shall be deemed to have terminated as of the date of the damage or destruction and Tenant shall immediately quit and surrender the demised premises to Landlord; provided that Tenant shall have sixty (60) days thereafter to remove its property from the demised premises." 11.

If Landlord and Tenant are unable to agree on the amount of such reduction within thirty (30) days after the mailing by Landlord of a written notice to Tenant that the premises have been so taken, then the reduction shall be an amount as shall be determined by arbitration as provided in this Sublease."

If Tenant shall not elect to terminate, this Sublease shall continue for the balance of its term as to the part of the demised premises remaining with no adjustment in rents payable hereunder; provided, that if the taking shall render the Improvement unusable by Tenant for the purposes set forth in Article 5 hereof, the Supplemental Rent shall abate."

If, within such thirty-day period, Landlord shall give written notice to Tenant of termination, this Sublease and the term hereof shall terminate and expire on the last day of the calendar month following the month in which such notice shall be given and the Basic Rent, Additional Rent, Supplemental Rent, and other sums or charges in this Sublease provided to be paid by Tenant shall be paid to the date of such termination; provided, that if Tenant shall agree in writing, within twenty (20) days after receiving any such notice of termination from Landlord, to pay the difference by which the cost of such restoration exceeds the sum allowed to Landlord in such condemnation proceeding, less such expenses, then Landlord's notice of termination and right to terminate hereunder shall cease and Landlord shall make such such restoration as herein before required." (d) by changing and amending subpart (e) to read as follows: "(e) Substantially all of the Premises or Original Building. For the purposes of this Article, aubstantially all of the demised premises or of the Original Building shall be deemed to be taken if the portion of the demised premises or Original Building not so taken does not constitute, or cannot be repaired or reconstructed so as to constitute, a complete plot and structures or, in the case of the Original Building, so as to constitute a complete structure, useable by Tenant as an entity for the proper conduct of its business as such business is described in Article 5. In the event of any dispute between Landlord and Tenant as to whether "substantially all" of the demised premises or of the Original Building are taken, such dispute shall be submitted to and determined by arbitration as provided in this Sublease." (e) by changing and amending subpart (f) to read as follows: "(f) Rents During Arbitration. The rents hereunder shall not abate during any arbitration proceeding or pending any arbitration award pursuant to this Article, but an adjustment in such rents, including a retroactive adjustment for any period during which Tenant may have been deprived of the use of either the Improvement or the Original Building, or any part of either, shall be made as soon as the exact amount thereof payable shall have been determined by the arbitration award." 12. Article 16 (Default) is hereby amended by changing and amending subpart (a)(i) thereof to read as follows: "(i) Rent Default. Tenant shall fail to pay installment of any of the rents due hereunder on the date that any thereof is due and such failure shall continue for a period of ten (l0) days after the giving of notice by Landlord of written demand for such payment; provided, however, that three (3) or more successive failures to pay any such rent within ten (10) days of the due date thereof shall constitute an event of default without the necessity of Landlord making any written demand;" 	13. Article 19 (Subordination and Attornment) is hereby amended by changing and amending subparagraph (b) thereof to read as follows: 	"(b) Nondisturbance. So long as Tenant is not in default in the payment of any rents due hereunder or in the performance of any of the terms of this Sublease, the Tenant's possession of the demised premises and the Tenant's rights and privileges under the Sublease or any renewal thereof shall not be diminished or interfered with by the mortgagee." 	14.
