* The initial monthly installment of Base Rent amount was calculated by multiplying the initial monthly Base Rent rate per rentable square foot amount by the number of rentable square feet of space in the Premises, and the annual Base Rent amount was calculated by multiplying the initial monthly installment of Base Rent amount by twelve (12). In all subsequent Base Rent payment periods during the Lease Term commencing on the first (1^st) day of the full calendar month that is Lease month 13, the calculation of each monthly installment of Base Rent amount reflects an annual

increase of three and one-half percent (3-1/2%) and each annual Base Rent amount was calculated by multiplying the corresponding monthly installment of Base Rent amount by twelve (12).

*** Subject to abatement as provided in Article 3 below. The Base Rent for this eight (8) month period is calculated based on 58,421 rentable square feet in the Premises notwithstanding that Tenant is leasing the entire Premises (consisting of 77,929 rentable square feet); provided, however, that Tenant shall pay Tenant's Share of Operating Expenses, Tax Expenses and Utilities Costs based on 77,929 rentable square feet in the Premises for the entire Lease Term.

5.Tenant's Share of Operating Expenses, Tax Expenses and Utilities Costs. Notwithstanding anything to the contrary in the Lease and effective as of the date hereof, Tenant's Share of Operating Expenses, Tax Expenses and Utilities Costs set forth in Section 9 of the Summary of the Lease is hereby deemed increased to 20.81%.

6.Brokers. Each party represents and warrants to the other that, except for Newmark Cornish & Carey ("Landlord's Broker") and Savills Studley ("Tenant's Broker"), it has no dealings with any real estate broker or an agent in connection with negotiating this First Amendment and it knows of no other broker, agent or finder who is entitled to a commission in connection with this First Amendment. Each party further agrees to defend, indemnify and hold harmless the other party from and against any claim for commission or finder's fee by any person or entity (other than Landlord's Broker or Tenant's Broker) who claims or alleges that they were retained or engaged by the first party or at the request of such party in connection with this First Amendment.
