Tenant's Share Percentages shall be calculated as follows: Tenant's Building Percentage shall be calculated by dividing the number of rentable square feet of the Premises by the total number of rentable square feet in the Building; and Tenant's Project Percentage shall be calculated by dividing the number of rentable square feet of the Premises by the total number of rentable square feet of all buildings in the Project. Consequently, any reference in this Lease to "Tenant's Share Percentage" shall mean and refer to Tenant's Building Percentage or Tenant's Project Percentage, as applicable.
