Each party shall bear the costs of the appraiser selected by such party, and the cost of the third appraiser shall be shared equally by Landlord and Tenant. If the three appraisers are unable to agree upon such fair market effective rent within fifteen (15) days of the appointment of the third appraiser, the fair market effective rent shall be that determined by the appraiser not selected by either Landlord or Tenant". 4. Section 4., RENT, is amended by deleting the third sentence in its entirety and inserting the following in its place: "Effective July 1, 1997, the Base Rent shall be Four Hundred Forty-Four thousand One Hundred Fifty-two and 00/100 Dollars ($444,152.00) per year payable in twelve (12) equal installments ("MONTHLY RENT") in check or money order on or before the first day of each calendar month, in the sum of Thirty-Seven Thousand Twelve and 67/100 Dollars ($37,012.67) each.
