In the event that any delay in delivery of possession of the Sixth Floor Expansion Space to Tenant past the date set forth in this Section 2(a) as the "Original Sixth Floor Expansion Space Term Commencement Date" is caused by or is attributable to the act or neglect of Tenant, its servants, agents, employees or independent contractors, including without limitation, as a consequence of any change orders to the Sixth Floor Expansion Space Approved Final Plans requested by Tenant and consented to by Landlord (provided that notice of such 8/3/94 anticipated delay shall be given by Landlord to Tenant) (collectively "Tenant's Acts"), the Sixth Floor Expansion Space Term Commencement Date shall be the later of the Original Sixth Floor Expansion Space Term Commencement Date or the date on which possession of the Sixth Floor Expansion Space would have been delivered to Tenant but for the delay caused by Tenant's Acts and Tenant shall be liable for Rent and other obligations under this Lease relating to the Sixth Floor Expansion Space from said Sixth Floor Expansion Space Term Commencement Date.

To the extent that Tenant is permitted by Landlord to enter the Sixth Floor Expansion Space the prior to the Sixth Floor Expansion Space Term Commencement Date to undertake such work as is to be performed by Tenant in order to prepare the Sixth Floor Expansion Space for Tenant's occupancy, such entry shall be deemed to be pursuant to a license from Landlord to Tenant and shall be at the risk of Tenant.
