Should Tenant fail to promptly pay to Landlord on demand any costs of the Leasehold Improvements in excess of the TI Allowance, Landlord may, at Landlord’s sole option, in addition to any other remedies available to Landlord under the Lease, at law or in equity, as a result of such default by Tenant, refuse to commence or immediately halt construction of the Leasehold Improvements until payment is received and Tenant shall bear all costs attributable to the stopping and re-starting of construction and any delay in completion thereof Notwithstanding anything to the contrary contained herein, Landlord may, upon notice to Tenant, require such changes to the Leasehold Improvements as Landlord reasonably determines to be appropriate in order to comply with the provisions of the Lease and with all applicable building and safety codes and other governmental and insurance requirements, which costs shall be paid from the TI Allowance or paid by Tenant (if in excess of the TI Allowance).

The foregoing provisions are a material part of the consideration for this Amendment.

Landlord will accommodate Tenant’s expansion request or not.

Notwithstanding the provision as provided below, in such event that the Landlord fails to deliver the space on or before one hundred fifty (150) days after the date the Landlord’s Notice is delivered, then Tenant, at its sole and exclusive remedy for such failure, shall have the right to terminate the Lease with thirty (30) days prior written notice if such notice is delivered prior to delivery of the Expansion Space. In the event Tenant elects to exercise its termination right as aforesaid, then Tenant, as a condition precedent to such exercise, shall pay to Landlord, at the time Tenant delivers the written notice of termination to Landlord, as an early termination fee, the sum of the (i) unamortized portion of the leasing commissions paid by Landlord in connection with this Amendment, plus, (ii) unamortized portion of the TI Allowance, each of (i) and (ii) being amortized at the Amortization Rate over months 8 — 67 of the Second Extended Term. The Expansion Space shall be delivered in its “AS-IS” “WHERE IS” AND “WITH ALL FAULTS” condition as of the Expansion Space Commencement Date.
