Upon making such a selection, the Independent Appraiser shall immediately give the Landlord and the Tenant written notice of this selection of the Fair Market Rental Value. The Fair Market Rental Value selected by the Independent Appraiser shall be used to calculate the new Base Monthly Rental which will be in effect during the Extension Option, and such selection by the Independent Appraiser shall be binding and conclusive upon the Landlord and the Tenant.
