Tenant shall, however, commence paying for utilities from and after the date of this Amendment. The Commencement Date of the Lease shall be March 1, 2018 regardless of whether Landlord’s Work is complete or Tenant has occupied the Premises; provided, however, if Tenant commences business operations in and from any portion of the Premises prior to March 1, 2018, the Commencement Date shall be the date Tenant commences business operations.
