Each portion of the leased Property will be subject to a 3% annual rent increase following availability. In addition to such base monthly rent, we will be obligated to pay triple net lease charges for operating expenses, taxes, insurance and utilities applicable to the leased Property. The Lease will expire on January 31, 2018 with respect to the entire premises.
